Description

Electric fishing reel

The present invention relates to an electric fishing reel.

As one of the fishing reels, electric fishing reels (hereinafter referred to as electric reels) are well known. In general, such electric reels are divided into two types: one in which the motor is arranged inside the reel and the other in which the motor is arranged further in front of the reel (the side in which the fishing line is continuously released).

Regardless of the form, the motor is housed in the motor housing portion formed in the cable reel body, and is kept housed in the motor housing portion by a cover-shaped motor base that closes the opening of the motor housing portion. At this time, the motor base needs to be firmly fixed to the cable reel body because it is easy to receive the thrust load from the motor and the radial load caused by the rotational torque. In the past, the motor base was often screwed to the cable reel body using fastening members such as screws and bolts (for example, refer to Patent Document 1).

[Patent Document 1] Japanese Patent Publication No. 2008-200025

However, when the motor base is screwed to the reel body, a flange with a screw insertion hole needs to be provided on the motor base side, and the flange is combined on the reel body side, and a screw receiving portion with a screw hole needs to be provided. In particular, the flange and the screw receiving portion need to be provided closer to the outer side in the radial direction than the opening of the motor housing portion. Therefore, not only will the size of the motor base itself be easily enlarged, but in order to cope with the enlargement, the size of the reel body is also easily enlarged. In particular, when the motor is arranged on the front side of the reel, there is a tendency for the size of the motor base, etc. to be easily enlarged.

Due to these circumstances, it is difficult to further miniaturize the electric cable reel, and there is room for improvement. In addition, in order to fix the motor base to the cable reel body, fastening components such as screws and bolts are required, which increases the number of parts and makes it difficult to achieve cost reduction and improve maintainability.

This invention was developed in view of this situation, and its purpose is to provide an electric fishing reel that can be miniaturized and have a reduced number of parts.

(1) The electric fishing reel of the present invention comprises: a reel body having a rotatable reel; a motor disposed in a motor housing tube provided in the reel body to drive the reel in rotation; and a motor base, which is combined with the reel body to seal the motor housing tube and fix the motor to the reel body, wherein the reel body comprises: a body frame having a side wall frame, the side wall frame being provided with the motor housing tube and forming an opening of the motor housing tube The motor base comprises: a cover body for sealing the opening of the motor storage tube; and a clamping part, which is formed in a manner of protruding from the cover body toward the radial outer side of the motor storage tube, and can be clamped in the circumferential direction of the motor storage tube with respect to the clamped part formed on the side wall frame or the side cover. The motor base is interposed between the side wall frame and the side cover to limit the movement of the motor in the motor axis direction.

When assembling the electric fishing reel according to the present invention, in order to seal the opening of the motor storage tube with the cover body, the motor base is assembled to the side wall frame, and then the side cover is assembled to the main body frame to cover the side wall frame. In this way, the motor base can be separated between the side wall frame and the side cover to limit the movement in the motor axis direction. That is, by separating the motor base between the side wall frame and the side cover, the motor base can be limited to move in the motor axis direction, and the opening of the motor storage tube can be sealed by the motor base.

Thus, when the motor disposed in the motor housing tube is driven, even if the thrust load caused by the drive is transmitted from the motor to the motor base, the motor base is restricted from moving in the motor axis direction, so it can receive the thrust load.

Furthermore, the motor base is not simply clamped between the side wall frame and the side cover, but also engages with the engaged portion formed on the side wall frame or the side cover in the circumferential direction of the motor housing tube on the radial outer side of the motor housing tube. Therefore, the movement of the motor base in the circumferential direction, that is, the movement of the motor base rotating around the motor axis is suppressed. Thus, when the motor is driven, even if the radial load around the motor axis caused by the rotational torque is transmitted from the motor to the motor base, the radial load can be received.

Due to the above situation, the motor base can not only correctly receive the thrust load and radial load from the motor, but also seal the opening of the motor housing tube, so that the motor arranged in the motor housing tube can be stably fixed.

In particular, when the motor base is assembled with the reel body, there is no need to use fastening components such as screws and bolts, so a large number of parts required for such fastening can be omitted. Therefore, the number of parts can be reduced, which helps to reduce the cost and improve the maintainability of the entire electric fishing reel. In addition, since there is no need for space for setting fastening components and there is no need to set components such as flanges for fastening, it is easy to set the motor base tightly, which helps to miniaturize the entire electric fishing reel.

(2) The aforementioned engaged portions are formed in a plurality of ways at intervals in the aforementioned circumferential direction, and the aforementioned engaging portion is preferably engaged with at least one of the aforementioned engaged portions in the aforementioned circumferential direction.

In this case, since a plurality of engaging parts are formed, when the motor base is assembled to the side wall frame, the engaging part can be engaged with the engaging part selected according to, for example, the assembly condition. Therefore, the assembly becomes easy and the assembly efficiency can be improved.

(3) The aforementioned engaging portion corresponds to the plurality of aforementioned engaged portions, and is formed in the aforementioned circumferential direction in a plurality of ways at intervals, and it is also preferred that the plurality of aforementioned engaged portions are engaged in the aforementioned circumferential direction.

In this case, since the motor base can be assembled while the engaged portion and the engaging portion are engaged at multiple locations, the radial load transmitted from the motor to the motor base can be received at multiple locations. Therefore, the posture of the motor base can be made more stable, and the motor can be fixed more stably. In addition, since the radial load is received at multiple locations, the load burden applied to the engaging portion of each location of the engaged portion and the engaging portion can be reduced. Therefore, the motor base can be assembled stably for a long time, which helps to improve the reliability of the product.

(4) The aforementioned engaged portion is formed on the aforementioned side wall frame, and a limiting member may also be provided on the aforementioned side cover, wherein the limiting member is between the aforementioned side wall frame and limits the movement of at least one of the aforementioned engaged portions in the direction of the motor axis.

In this case, when the motor base is assembled to the side wall frame, the engaging portion formed on the side wall frame can be engaged in the circumferential direction. In this way, the motor base can be assembled while suppressing the movement of rotation around the motor axis. In particular, since the engaging portion is formed on the side wall frame constituting the main body frame, the main body frame with high rigidity can block the radial load transmitted from the motor to the motor base, and the posture of the motor base can be more easily stabilized.

Furthermore, by assembling the side cover to the main body frame to cover the side wall frame, the motor base can be separated between the side wall frame and the side cover, and the movement of the engaging part itself in the motor axis direction can be restricted by the restricting member. Therefore, the thrust load and radial load transmitted to the motor base can be efficiently received through the engaging part at the same time.

According to the present invention, an electric fishing reel can be made that can be miniaturized and have a reduced number of parts.

The following is a description of the implementation of the electric fishing reel of the present invention with reference to the drawings. In this implementation, a double-bearing fishing reel is used as an example for explanation.

As shown in Fig. 1 to Fig. 4, the electric reel (the electric reel for fishing of the present invention) 1 of the present embodiment mainly comprises: a reel body 2 which can be mounted on a fishing rod (not shown); a handle 3 which can be mounted on the reel body 2 so as to be rotatable around a handle axis O1; a reel 4 which can be rotated around a reel axis O2 which is parallel to the handle axis O1 and around which a fishing line (not shown) is wound on the reel body 2; and a clutch mechanism 6 having a clutch operating rod 5.

Moreover, the electric cable reel 1 of this embodiment is shown in FIG. 5 to FIG. 7 and comprises: a motor 8 disposed in a motor housing tube 7 provided in the cable reel body 2 to drive the reel 4 to rotate; and a motor base 9, which is combined with the cable reel body 2 to seal the motor housing tube 7 and fix the motor 8 to the cable reel body 2.

In this embodiment, the handle axis O1 and the reel axis O2 are arranged parallel to each other, and the direction along these axes is defined as the left-right direction L1. In addition, the direction perpendicular to the left-right direction L1 and along the direction in which the fishing line wound on the reel 4 is continuously released is defined as the front-back direction L2.

Furthermore, the direction in which the fishing line is continuously released from the reel 4 in the front-rear direction L2 is defined as the front, and the opposite direction is defined as the rear, and the viewpoint of viewing the electric reel 1 from the rear side (the angler's side) is defined as the left and right. Therefore, for example, FIG1 is a three-dimensional view of the electric reel 1 viewed from the upper left rear.

(Reel body)

As shown in FIGS. 1 to 4 , the cable reel body 2 includes a body frame 10 , side covers 20 covering the left and right sides of the body frame 10 , and a front cover 30 covering the front side of the body frame 10 .

The main body frame 10 is a molded member made of, for example, synthetic resin or metal (e.g., aluminum die casting). The main body frame 10 includes: a first side wall 11 and a second side wall 12 arranged to face each other in the left-right direction L1 across the reel 4; and a connecting member 13 connecting the first side wall 11 and the second side wall 12 to each other in the left-right direction L1.

The first side wall (the side wall frame of the present invention) 11 is a left side wall arranged on the left side (LH) for the roll 4. In contrast, the second side wall 12 is a right side wall arranged on the right side (RH) for the roll 4. Furthermore, the handle 3 is arranged on the right side (RH) of the second side wall 12 and is mounted on the main body frame 10 using the second side wall 12.

Therefore, the electric reel 1 of this embodiment is a right-handle type reel. Furthermore, the second side wall 12 is formed to protrude further downward than the first side wall 11 in order to provide the connector portion 23 described later.

The connecting member 13 is formed into a plate shape that connects the first side wall 11 and the second side wall 12 to each other in the left-right direction L1, and is arranged near the lower part of the first side wall 11. Thus, the first side wall 11 and the second side wall 12 are strongly connected via the connecting member 13.

Furthermore, a mounting leg 14 for mounting the electric reel 1 on the fishing rod is formed in the central portion of the connecting structure 13 in the left-right direction L1, and extends along the front-rear direction L2.

In the main body frame 10 constructed as described above, between the first side wall 11 and the second side wall 12, at least a motor housing tube 7 for arranging the motor 8 inside, a drum 4, and a clutch operating rod 5 are arranged.

The reel 4 is disposed between the first side wall 11 and the second side wall 12 so as to be located further rearward than the handle axis O1. The motor storage tube 7 is disposed between the first side wall 11 and the second side wall 12 so as to be located further forward than the handle axis O1. Therefore, the electric cable reel 1 of this embodiment is a so-called spool-out motor type in which the motor 8 is disposed further forward than the reel 4.

Furthermore, the motor housing tube 7 is disposed between the first side wall 11 and the second side wall 12 in a manner such that the opening portion 62 is formed on the first side wall 11.

The side cover 20 includes: a first side cover (the side cover of the present invention) 21 assembled to the main body frame 10 in a manner of covering the first side wall 11 on which the opening of the motor housing tube 7 is formed from the left side (LH); and a second side cover 22 assembled to the main body frame 10 in a manner of covering the second side wall 12 from the right side (RH).

The first side cover 21 is formed in a manner that expands toward the left side (LH) and is fixed to the first side wall 11, for example, by screws. Thereby, a predetermined storage space is formed between the first side cover 21 and the first side wall 11. In addition, the first side cover 21 will be described in detail later.

The second side cover 22 is formed in a manner that expands toward the right side (RH) and is fixed to the second side wall 12 by, for example, screws. Thus, a predetermined storage space is formed between the second side cover 22 and the second side wall 12.

In the lower front portion of the second side cover 22, a power reel cord for supplying power from an external power source or a connector 23 for connecting a portable battery is installed with the unillustrated connection end facing downward. In addition, in each figure, the connection end is protected by a protective cover 24.

The front cover 30 is assembled to the main body frame 10 in a manner that covers the front part of the main body frame 10 from the front. Specifically, the front cover 30 is assembled to the front part of the first side wall 11 and the second side wall 12 in a manner that covers the motor storage tube 7 from the front, and the first side wall 11 and the second side wall 12 are fixed, for example, by screws. Furthermore, the front cover 30 is installed so as not to block the moving area of the uniform winding frame 55 described later.

(Counter Box)

A counter box 40 is provided on the upper portion of the main body frame 10 constructed as described above. The counter box 40 is arranged between the first side wall 11 and the second side wall 12 and is fixed to the upper portion of the first side wall 11 and the upper portion of the second side wall 12 by, for example, screw fixing.

The counter box 40 mainly comprises: a thin outer shell body 41 which is longer in the front-rear direction L2 than in the left-right direction L1; a display unit 42 provided in the outer shell body 41; and a motor control unit (not shown) provided in the outer shell body 41.

The display unit 42 is constituted by, for example, a liquid crystal display, and is exposed on the upper surface of the housing body 41 while being protected by a glass cover. The motor control unit is constituted by a microcomputer equipped with, for example, a CPU, and controls the motor 8 and performs display control such as displaying various information on the display unit 42.

The motor control unit receives control signals from a plurality of (three in the illustrated example) operation buttons 43 disposed on the upper surface of the housing body 41, a control signal from an operation switch 44 disposed on the upper surface of the housing body 41, and a control signal from a reel sensor (e.g., a sensor for detecting the rotation speed and rotation direction of the reel 4) not shown in the diagram.

Thus, the motor control unit can display various information such as the time of the fishing group being put into the water, the water depth of the fishing group, the winding speed or winding torque of the motor 8 on the display unit 42 according to various control signals, and can also control the rotation of the motor 8 in response to the operation of the operating switch 44, and arbitrarily adjust the winding speed or winding acceleration, etc.

Therefore, the angler can perform manual reeling operation by operating the handle and automatic reeling operation by operating the switch 44.

[Handle]

The handle 3 is arranged on the right side (RH) of the main body frame 10 and the first side cover 21. The handle 3 has: a handle axis 50 rotatably arranged around the handle axis O1; a handle arm 51 non-rotatably mounted on the handle axis 50; and a handle knob 52 rotatably mounted on the end of the handle arm 51 around an axis parallel to the handle axis O1.

Between the handle arm 51 and the first side cover 21, there is a drag part 53 (star-shaped fishing force valve) coaxially arranged with the handle axis O1. When winding the fishing line, the drag part 53 applies an arbitrary drag force to the reel 4 to brake the rotation of the reel 4, thereby playing a role in preventing the fishing line from being cut.

The rotational torque from the handle 3 constructed in this way is directly transmitted to the reel 4 through a rotation transmission mechanism (not shown) when the clutch mechanism 6 is in the clutched and opened state.

Furthermore, in this embodiment, a so-called single handle type in which a handle knob 52 is installed at one end of the handle arm 51 is used as an example for explanation, but it is not limited to such a case. For example, it is also possible to be a so-called double handle type electric cable reel 1 in which handle knobs 52 are installed at both ends of the handle arm 51 and the central part of the handle arm 51 is non-rotatably installed on the handle shaft 50.

(Reel)

The reel 4 is disposed between the first side wall 11 and the second side wall 12 of the frame body, and is supported by the first side wall 11 and the second side wall 12 respectively so as to be rotatable around the reel axis O2 via bearings not shown.

The reel 4 includes: a reel rotating shaft (not shown) that can rotate around the reel axis O2; and a reel main body 4a that is coaxially arranged with the reel rotating shaft and rotates in conjunction with the reel rotating shaft.

(Clutch mechanism)

The clutch mechanism 6 can switch between a clutch open state in which the rotational torque from the handle 3 can be transmitted to the reel 4 via a rotation transmission mechanism (not shown) and a clutch closed state in which the rotational torque cannot be transmitted by operating the clutch operating lever 5. Therefore, in the clutch open state, by rotating the handle 3, the rotational torque accompanying the rotational operation of the handle 3 can be transmitted to the reel 4, and the reel 4 can be rotated around the reel axis O2. In this way, manual reeling operation can be performed.

Furthermore, when the clutch mechanism 6 is in the clutch-off state, the rotational torque accompanying the rotational operation of the handle 3 will not be transmitted to the reel 4, and the reel 4 becomes a freely rotatable state (reel free state).

The clutch operating lever 5 is a switching lever used to switch the clutch mechanism 6 between the clutch open state and the clutch closed state. The clutch operating lever 5 is disposed further behind the drum 4, between the first side wall 11 and the second side wall 12, and moves up and down in a manner that allows it to swing around the drum axis O2.

Furthermore, the rotation transmission mechanism transmits the rotation torque to the reel 4 while accelerating the rotation of the handle 3. Moreover, when the clutch mechanism 6 is in the clutch open state, the rotation transmission mechanism transmits the rotation torque accompanying the rotation operation of the handle 3 not only to the reel 4, but also to the uniform winding mechanism (not shown) having the uniform winding frame 55.

Furthermore, the uniform winding frame 55 is arranged between the motor storage tube 7 and the counter box 40, between the first side wall 11 and the second side wall 12, and can reciprocate in the left and right direction L1 along with the rotation of the reel 4 (refer to Figure 3). In this way, the fishing line can be evenly wound around the reel 4 without bias.

Furthermore, when the clutch mechanism 6 is in the clutch open state and the motor 8 is driven, the rotational torque accompanying the driving of the motor 8 can be transmitted to the reel 4. In this way, automatic winding operation can be performed. Furthermore, the rotational transmission mechanism transmits the rotational torque to the reel 4 while decelerating the rotation of the motor 8.

(Motor storage tube)

As shown in FIG3 , the motor housing tube 7 is disposed between the first side wall 11 and the second side wall 12 at the front side of the handle axis O1 and is formed into a topped cylinder coaxially disposed with the motor axis O3 extending in the left-right direction L1.

Specifically, the motor housing tube 7 is formed into a bottomed cylinder as shown in Figures 5 to 8, and has a cylindrical housing tube body 60 formed in a cylindrical shape with the motor axis O3 as the center; and a bottom wall 61 that closes the right side opening 62 of the housing tube body 60. Thus, the motor housing tube 7 has an opening 62 on the first side wall 11, which opens to the left side (LH).

Furthermore, in the example shown in the figure, the storage tube body 60 and the bottom wall 61 are formed integrally, but the present invention is not limited to this case. For example, the storage tube body 60 and the bottom wall 61 may be formed separately, and the storage tube body 60 and the bottom wall 61 may be combined integrally by screw connection, threading, or fitting.

Furthermore, in this embodiment, when viewed from the motor axis O3 direction, the direction intersecting the motor axis O3 is called the radial direction, and the direction surrounding the motor axis O3 is called the circumferential direction.

As shown in FIG3 , the storage tube body 60 is arranged below the uniform winding frame 55 and is located between the front portion of the first side wall 11 and the front portion of the second side wall 12. Therefore, the motor storage tube 7 is arranged to be exposed to the front. The motor storage tube 7 is partially protected from the front side by the front cover 30.

As shown in Figures 5 to 8, a portion of the housing tube body 60 located on the side of the opening portion 62 is formed with an expansion tube 63 having a larger diameter than other portions. Therefore, the motor housing tube 7 is integrally formed on the first side wall 11 via the expansion tube 63. In addition, a cylindrical hub 64 is formed in the central portion of the bottom wall 61, which protrudes toward the right side (RH).

Here, the first side wall 11 constituting the main frame 10 is described in detail.

As shown in FIG5 , the first side wall 11 functions as the left side wall of the main body frame 10 and is normally covered by the first side cover 21. The first side wall 11 is formed longer in the front-rear direction L2 than in the up-down direction. As mentioned above, the motor housing cylinder 7 is integrally formed on the front side, and the contour of the lower front side of the main body frame 10 is formed concentrically with the motor housing cylinder 7. The rear side of the first side wall 11 is formed in a semicircular shape in the side view angle that expands toward the rear.

As described above, a counter box 40 is arranged above the first side wall 11. The counter box 40 is screwed to the upper side of the first side wall 11 by fixing screws 70. In the example shown in the figure, the counter box 40 is fixed by two fixing screws 70 arranged at intervals in the front-rear direction L2.

Various components (such as bearings, gears, receiving components, etc.) constituting the electric reel 1 are arranged in the first side wall 11, which is located further rearward than the motor housing tube 7. In addition, at the outer peripheral portion of the first connecting wall, an edge 71 protruding toward the left side (LH) is continuously formed in a manner extending along the outer peripheral portion.

Furthermore, a connecting screw 72, a screw hole 73 and a receiving tube 74 are formed on the first side wall 11 for mounting the first side cover 21.

As shown in FIG. 5 and FIG. 6 , two connecting screws 72 are formed on the upper side of the first side wall 11 in a manner separated in the front-rear direction L2 with two fixing screws 70 for mounting the counter box 40 in between. The connecting screws 72 are installed from the side of the storage tube body 60 and protrude to the left side (LH). Furthermore, the number of connecting screws 72 is not limited to two and can be changed as appropriate.

The screw hole 73 is formed at the lower side of the first side wall 11 and is located in the central part of the front-rear direction L2. The receiving cylinder 74 is a cylinder component with a hollow interior and an opening toward the left side (LH), and is formed in the first side wall 11 and is located in front of the screw hole 73.

(Motor)

As shown in Figures 7 and 9, the motor 8 is housed in the motor housing tube 7 and has: a motor output shaft 80 that rotates around the motor axis O3; and a motor body 81 that is used to rotate and drive the motor output shaft 80.

The motor output shaft 80 is arranged coaxially with the motor axis O3 in such a way that the motor body 81 is passed through in the direction of the motor axis O3. At this time, the motor output shaft 80 is formed to protrude to the left (LH) of the first side wall 11 and to the right (RH) of the hub 64. In addition, the motor output shaft 80 is simplified in each figure.

The motor output shaft 80 is stably supported by a plurality of bearings including a bearing 83 installed on the inner side of the hub 64. Furthermore, an annular motor waterproof seal 84 is installed on the inner side of the hub 64, adjacent to the right side (RH) of the bearing 83. The motor waterproof seal 84 is an inner peripheral portion slidingly connected to the entire outer peripheral surface of the motor output shaft 80. This can limit water or dust from entering the motor storage tube 7.

At the left end of the motor output shaft 80, a sawtooth groove (sawtooth-shaped groove) 85 is formed on the outer side (left side (LH)) of the first side wall 11. The sawtooth groove 85 is coupled with a one-way clutch 86 installed on the motor base 9 described later. Thereby, the motor output shaft 80 is restricted from rotating (reversing) in the direction of continuously releasing the fishing line. Therefore, the motor 8 is only allowed to rotate in one direction for winding the fishing line. Furthermore, the installation position of the one-way clutch 86 is not limited to the motor base 9, and can be appropriately changed.

The motor body 81 comprises: a bottomed cylindrical outer shell body 81a opened to the left (LH); and an end cap 81b sealing the left opening of the outer shell body 81a. In the end cap 81b, a connecting cable 87 is inserted at intervals in the circumferential direction, for example, and the connecting cable connects the motor body 81 to the motor control unit arranged in the counter box 40. In the example shown in the figure, two connecting cables 87 are arranged at equal intervals in the circumferential direction (specifically, arranged to face each other in the radial direction across the motor axis O3).

Moreover, the motor body 81 mainly comprises: a rotor, which is fixed to the motor output shaft 80 and has, for example, a coil; a stator, which is arranged in the outer shell body 81a in a manner of surrounding the rotor from the outer side in the radial direction and has a permanent magnet; a commutator; and a brush.

The motor 8 constructed as described above is electrically connected to the motor control unit (see FIG. 5 ) via the connecting cable 87 , and the drive is controlled by the motor control unit.

Furthermore, the space of the motor housing tube 7 located to the right (RH) of the bottom wall 61 is provided with a deceleration mechanism (not shown) that decelerates the rotational torque of the motor output shaft 80 and transmits it to the reel 4. Furthermore, the structure of the motor 8 can be appropriately changed, and a brushless motor, for example, can also be used.

(1st side cover)

The first side cover 21 is described in detail.

As shown in Figures 1 to 4 and 10, the first side cover 21 is a cover member corresponding to the shape of the first side wall 11, which is formed to be longer in the front-rear direction L2 than in the up-down direction, and covers the first side wall 11 from the left side (LH). More specifically, the first side cover 21 is not only the first side wall 11, but also a part of the motor base 9, the front cover 30, and the counter box 40 installed to seal the motor storage tube 7 from the left side (LH), and is assembled on the main body frame 10.

The first side cover 21 includes: a cover body 90 formed to expand toward the left side (LH); and a peripheral portion 91 bent toward the right side (the first side wall 11 side) from the outer peripheral portion of the cover body 90 over the entire periphery of the outer peripheral portion.

The peripheral portion 91 of the first side cover 21 can contact the edge 71 of the first side wall 11, the side edge of the front cover 30, and the side surface of the counter box 40 without any gap. In this way, a structure can be made that makes it difficult for water, dust, etc. to enter the interior of the first side cover 21. In addition, the peripheral portion 91 at the lower side of the front portion of the first side cover 21 cooperates with the main body frame 10 to form a concentric circle with the motor housing tube 7.

Furthermore, the cover body 90 has a receiving cylinder 92 and a connecting pin 93 protruding toward the first side wall 11, and an insertion hole 95 for inserting a connecting screw 94 is formed.

Two screw receiving barrels 92 are provided corresponding to the two connecting screws 72 formed on the first side wall 11, and are arranged at intervals in the front-rear direction L2 in a manner that the connecting screws 72 face each other in the left-right direction L1. The screw receiving barrels 92 are barrel components with female threaded portions formed on the inner circumference and opening toward the right side (the first side wall 11 side), which can be threaded with the connecting screws 72.

The connecting pin 93 is arranged to face the receiving tube 74 formed on the first side wall 11 in the left-right direction L1, and is formed to protrude to the right side (RH). The connecting pin 93 is formed, for example, in a cylindrical shape and can enter the inside of the receiving tube 74 formed on the first side wall 11. The insertion hole 95 is arranged to face the screw hole 73 formed on the first side wall 11 in the left-right direction L1, and is formed to penetrate the cover body 90 in the left-right direction L1.

When the first side cover 21 constructed as described above is assembled to the main body frame 10, the first side wall 11 is covered from the left side (LH) while the connecting pin 93 is inserted into the receiving tube 74 formed on the first side wall 11. At this time, the first side cover 21 can be guided by inserting the connecting pin 93 into the receiving tube 74, so that the first side cover 21 is correctly assembled to the main body frame 10, and thus the side cover 20 can be easily and correctly covered. After the first side cover 21 covers the main body frame 10, the connecting screw 94 is screwed into the screw hole 73 from the left side (LH) of the first side cover 21 through the insertion hole 95, and the connecting screw 72 is screwed into the female threaded portion in the screw receiving cylinder 92 of the first side cover from the right side (RH) while passing through the main body frame 10.

Thus, the first side cover 21 can be screwed to the main body frame 10 while the peripheral portion 91 of the first side cover 21 contacts the edge 71 of the first side wall 11, the side edge of the front cover 30, and the side surface of the counter box 40 without any gap.

Furthermore, since the contour of the lower front side of the first side cover 21 is formed to be roughly concentric with the motor housing tube 7, that is, the motor 8, it is formed into an outer shape corresponding to the shape of the motor 8, etc., and can be made into a shape that eliminates unnecessary molded parts. Therefore, it is possible to seek to improve the appearance and design.

(Motor base)

As shown in Figures 5 to 7, 11 and 12, the motor base 9 is assembled on the first side wall 11 of the reel body 2 to seal the motor housing tube 7, and plays the role of fixing the motor 8 to the reel body 2.

The motor base 9 is provided with: a top cylindrical cover 100 that seals the opening 62 of the motor housing tube 7; and a locking protrusion (locking part of the present invention) 101 that is formed in a manner of protruding outward in the radial direction from the cover 100 and can be locked in the circumferential direction with the locking recess (locked part of the present invention) 120 formed on the first side wall 11.

The cover 100 is arranged coaxially with the motor axis O3, and has: a fitting tube 102, which fits into the inner side of the expansion tube 63 of the motor storage tube 7; and a closing wall 103, which is used to close the left side opening of the fitting tube 102. In addition, a storage tube portion 104 with a top cylinder is formed in the central part of the closing wall 103 in a manner coaxially arranged with the motor axis O3, and it protrudes to the left side (LH). Thereby, the cover 100 is formed into a top cylinder with the central part of the closing wall 103 partially expanding toward the left side (LH).

An annular groove 105 that is recessed inward in the radial direction is formed on the outer circumference of the fitting tube 102 over the entire circumference. An O-ring 106 (see FIG. 7 ) is installed in the annular groove 105 to form a close contact with the inner circumference of the expansion tube 63. In this way, the O-ring 106 can be used to properly seal the fitting tube 102 and the expansion tube 63, and water or dust can be prevented from entering the motor housing tube 7 from the first side wall 11.

Furthermore, the annular groove 105 does not necessarily have to be formed on the outer peripheral surface of the fitting tube 102, but can also be formed on the inner peripheral surface of the expansion tube 63. Even in this case, the O-ring 106 can be used to properly seal the fitting tube 102 and the expansion tube 63.

Furthermore, the fitting tube 102 is not entirely arranged on the inner side of the expanding diameter tube 63, but a part of it is arranged on the outer side (left side (LH)) of the expanding diameter tube 63, and serves as a slightly expanded large diameter tube 107. The large diameter tube 107 is continuously arranged on the outer peripheral portion of the closing wall 103. In addition, the large diameter tube 107 contacts the first side wall 11 from the left side (LH). In this way, the fitting tube 102 can be correctly embedded in the expanding diameter tube 63.

The closed wall 103 is provided with a through hole 108 for inserting the connection cable 87 for connecting the motor 8 to the motor control unit, which penetrates the closed wall 103. In the example shown in the figure, four through holes 108 are formed at equal intervals in the circumferential direction, and two of the through holes 108 are respectively inserted with two connection cables 87 for inserting the end cap 81b. In this way, the connection cable 87 can be wired between the motor 8 and the motor control unit.

Furthermore, motor fixing screws 109 are installed in the remaining two through holes 108, which are used to be screwed into the screw holes 109a formed in the end cover 81b (refer to Figure 9). Thereby, the motor body 81 is fixed to the motor base 9.

Therefore, after the motor base 9 and the motor body 81 are fixed to each other, the motor body 81 can be accommodated in the motor accommodating tube 7. Furthermore, FIG. 9 shows the state where the motor base 9 is intentionally removed from the state shown in FIG. 6.

The aforementioned one-way clutch 86 is installed on the inner side of the storage cylinder 104, and the left end of the motor output shaft 80 is stored.

The engaging protrusion 101 is formed to protrude outward in the radial direction from the outer peripheral surface of the large diameter cylinder 107. In this embodiment, two engaging protrusions 101 are formed at equal intervals in the circumferential direction. That is, the engaging protrusion 101 is composed of a first engaging protrusion 111 and a second engaging protrusion 112. Thus, the first engaging protrusion 111 and the second engaging protrusion 112 are arranged to face each other in the radial direction across the motor axis O3.

The first engaging protrusion 111 and the second engaging protrusion 112 can engage with the engaging recess 120 formed on the first side wall 11 in the circumferential direction.

Next, the engaging recess 120 will be described.

As shown in Figs. 6, 7 and 9, a first engaging recess 121 is formed in the portion of the edge 71 of the first side wall 11 that is located further forward than the motor base 9 and is recessed toward the right side (RH). The first engaging protrusion 111 is engaged in the circumferential direction by being inserted into the first engaging recess 121 from the left side (LH).

In addition, a locking plug 125 is fixed to the portion of the first side wall 11 that is located on the opposite side of the first locking recess 121 in the radial direction across the motor axis O3. The locking plug 125 can be formed integrally with the first side wall 11, or can be formed as a separate body and assembled to the first side wall 11.

The engaging plug 125 is provided with: a base end portion 127 positioned at the first side wall 11 by a positioning pin 126; and an engaging claw portion 128 formed in a double fork shape. Moreover, the inner side of the engaging claw portion 128 is a second engaging recess 122 opened toward the motor base 9. The second engaging protrusion 112 is engaged in the circumferential direction by being inserted into the second engaging recess 122 from the left side (LH). Furthermore, a screw hole 129 is formed at the base end portion 127.

As described above, the engaging recess 120 (i.e., the first engaging recess 121 and the second engaging recess 122) is formed with two engaging protrusions 101 (i.e., the first engaging protrusion 111 and the second engaging protrusion 112) in the circumferential direction, and the two engaging protrusions 101 (i.e., the first engaging protrusion 111 and the second engaging protrusion 112) can engage with the engaging recess 120 in the circumferential direction.

The motor base 9 constructed as described above is limited in movement toward the motor axis O3 by being separated between the first side wall 11 and the first side cover 21 as shown in FIG13. Specifically, a limiting protrusion (limiting member of the present invention) 130 is provided on the first side cover 21, which limits the movement of the motor base 9 toward the motor axis O3 by pressing the first engaging protrusion 111 from the left side (LH) between the first side wall 11.

As shown in FIG10 , the limiting protrusion 130 is formed in a manner of protruding from the inner side of the peripheral portion 91 of the first side cover 21 toward the first engaging protrusion 111. When the first side cover 21 is assembled to the main frame 10 (refer to FIG13 ), the first engaging protrusion 111 is pressed from the left side (LH). Thus, the limiting protrusion 130 can be used to prevent the first engaging protrusion 111 from being disengaged from the first engaging recess 121, and the motor base 9 can be clamped between the first side wall 11 and the first side cover 21 to limit its movement in the direction of the motor axis O3.

In addition, in this embodiment, as shown in FIG. 5 to FIG. 7, a limiting screw 135 is also provided, which is screwed into a screw hole 129 formed at a base end portion 127 of the engaging plug 125, and the limiting screw 135 is used to press the second engaging protrusion 112 from the left side (LH). That is, for the engaging protrusion 101, the limiting screw 135 can be used to limit the engaging protrusion 101 (the second engaging protrusion 112) different from the engaging protrusion 101 (the first engaging protrusion 111) that is limited by the limiting protrusion 130 to move in the direction of the motor axis O3.

Specifically, the head of the limiting screw 135 is used to limit the movement of the second engaging protrusion 112 in the direction of the motor axis O3.

(The function of electric reel)

Next, the use of the electric wire reel 1 constructed as described above will be described.

In this electric cord reel 1, a power cord electrically connected to an external power source or a portable storage battery is electrically connected to the connector portion 23. This allows power to be supplied to the motor 8, and the motor 8 can be driven.

Furthermore, by operating the clutch operating lever 5, the clutch mechanism 6 is made into the clutch closed state, and the reel 4 can be rotated freely, so that the fishing line can be continuously fed out and the fishing group can be thrown into the water. Then, the clutch operating lever 5 is operated to switch the clutch mechanism 6 to the clutch open state, and then the reel 4 can be rotated by rotating the handle 3, for example, to perform manual winding of the fishing line. Alternatively, by operating the switch 44, the motor 8 is driven to rotate the reel 4, thereby performing automatic winding of the fishing line. In this way, the electric reel 1 can be used for fishing.

Furthermore, when assembling the electric cable reel 1 according to the present embodiment, in order to seal the opening 62 of the motor housing tube 7 with the cover 100, after assembling the motor base 9 to the first side wall 11, as shown in FIGS. 1 to 4, the first side cover 21 is assembled with the main body frame 10 to cover the first side wall 11.

In this way, the motor base 9 can be clamped between the first side wall 11 and the first side cover 21, and as shown in FIG13, the first engaging protrusion 111 can be pressed from the left side (LH) by using the limiting protrusion 130 to limit the movement of the motor base 9 in the direction of the motor axis O3. In this way, the movement of the motor base 9 in the direction of the motor axis O3 can be limited, and the opening 62 of the motor housing tube 7 can be sealed by the motor base 9.

Therefore, when the motor 8 disposed in the motor housing tube 7 is driven, even if the thrust load caused by the driving is transmitted from the motor 8 to the motor base 9, the motor base 9 is restricted from moving in the direction of the motor axis O3, so the thrust load can be received.

Furthermore, as shown in FIG6 and FIG7, the motor base 9 engages the engaging recess 120 (i.e., the first engaging recess 121, the second engaging recess 122) formed on the first side wall 11 and the engaging protrusion 101 (i.e., the first engaging protrusion 111, the second engaging protrusion 112) in the circumferential direction. Therefore, the movement of the motor base 9 in the circumferential direction, that is, the movement of the motor base 9 rotating around the motor axis O3 is suppressed. Thus, when the motor 8 is driven, even if the radial load around the motor axis O3 caused by the rotational torque is transmitted from the motor 8 to the motor base 9, the radial load can be received.

Due to the above situation, the motor base 9 can not only correctly receive the thrust load and radial load from the motor 8, but also seal the opening 62 of the motor housing tube 7, so that the motor 8 disposed in the motor housing tube 7 can be stably fixed.

In particular, when the motor base 9 is assembled with the cable reel body 2, it is not necessary to use fastening components such as screws and bolts, so a large number of parts required for such fastening can be omitted. Therefore, the number of parts can be reduced, which helps to reduce the cost and improve the maintainability of the entire electric cable reel 1. In addition, since there is no need for a space for setting fastening components and there is no need to set components such as flanges for fastening, it is easy to tightly set the motor base 9, which helps to miniaturize the entire electric cable reel 1.

In particular, when the motor 9 is arranged at the lower front side of the reel body 10, as described above, since the peripheral portion 91 at the lower front side of the first side cover 21 is formed concentrically with the motor housing tube 7, redundant molded parts can be eliminated, which can improve the appearance and design.

Therefore, the electric wire reel 1 according to this embodiment can be used as an easy-to-use electric wire reel 1 that can be miniaturized and have a reduced number of parts.

In this case, since the motor base 9 can be assembled by the engagement of the first engagement recess 121 with the first engagement protrusion 111 and the engagement of the second engagement recess 122 with the second engagement protrusion 112, the radial load transmitted from the motor 8 to the motor base 9 can be received at multiple locations (two locations). Therefore, the posture of the motor base 9 can be made more stable, and the motor 8 can be fixed more stably. In addition, since the radial load is received at multiple locations (two locations), the load burden applied to the engagement portion of each location can be reduced. Therefore, the motor base 9 can be assembled stably for a long time, which helps to improve the reliability of the product.

Furthermore, when the motor base 9 is assembled to the first side wall 11, the first engaging recess 121 and the second engaging recess 122 formed on the first side wall 11 are engaged with the first engaging protrusion 111 and the second engaging protrusion 112 in the circumferential direction. Thus, the motor base 9 can be assembled while suppressing the movement of the motor rotating around the motor axis O3.

In particular, since the first engaging recess 121 and the second engaging recess 122 are formed on the first side wall 11 constituting the main frame 10, the main frame 10 having high rigidity can block the radial load transmitted from the motor 8 to the motor base 9, and the posture of the motor base 9 can be more easily stabilized.

Furthermore, since the limiting protrusion 130 can limit the movement of the first engaging protrusion 111 itself toward the motor axis O3, the thrust load and radial load transmitted to the motor base 9 can be efficiently received through the first engaging protrusion 111 at the same time.

Furthermore, since the limiting screw 135 can limit the movement of the second engaging protrusion 112 itself toward the motor axis O3, the thrust load and radial load transmitted to the motor base 9 can be efficiently received through the second engaging protrusion 112 at the same time.

The above describes the implementation forms of the present invention, but these implementation forms are examples of the present invention and are not used to limit the scope of the invention. The implementation forms can be implemented in various other forms, and various omissions, substitutions, changes, etc. can be made without exceeding the scope of the idea of the present invention. The implementation forms and their variations include, for example, those that are easy for the industry to think of, those that are substantially the same, and those of equal scope, etc.

For example, in the aforementioned embodiment, a separate motor type in which the motor storage tube 7 is arranged in front of the reel 4 is used as an example for explanation, but this is not limited to the case, and a spool-in motor type in which the motor storage tube 7 is stored inside the reel 4 may also be used.

Furthermore, in the above-mentioned embodiment, the motor housing tube 7 is opened toward the first side wall 11 as a right-handle type. However, the motor housing tube 7 may be opened toward the second side wall 12 as a left-handle type. In this case, the same effect can be obtained.

In addition, in the above-mentioned embodiment, the case where two engaging recesses 120 and two engaging protrusions 101 are formed respectively is described as an example, but it is not limited to this case. For example, the engaging recess 120 and the engaging protrusion 101 may be formed as one each, or may be formed as three or more each.

Furthermore, the number of the engaging recesses 120 and the number of the engaging protrusions 101 do not necessarily have to be the same, and for example, one engaging protrusion 101 may be formed, and in contrast, two or more engaging recesses 120 may be formed. In this case, when the motor base 9 is assembled to the first side wall 11, the engaging protrusion 101 may be engaged with the engaging recess 120 selected in response to, for example, the assembly condition. Therefore, assembly becomes easier, which can help improve assembly efficiency.

Furthermore, in the above-mentioned embodiment, the case where the engaging recess 120 is formed on the first side wall 11 is described as an example, but it is not limited to this case, and it can also be formed on the first side cover 21. Even in this case, when the first side cover 21 is assembled to the main frame 10, the engaging recess 120 and the engaging protrusion 101 can be engaged in the circumferential direction, so the same effect can be achieved.

However, the above-mentioned embodiment is more ideal because the engaging recess 120 is formed on the first side wall 11, and the engaging recess 120 and the engaging protrusion 101 can be properly engaged in the circumferential direction before the first side cover 21 is assembled.

Furthermore, in the aforementioned embodiment, the limiting protrusion 130 is used to limit the movement of the motor base 9 in the direction of the motor axis O3, but this is not limited to the case. For example, the first side cover 21 itself can clamp the motor base 9 between the first side wall 11 to limit the movement of the motor base 9 in the direction of the motor axis O3.
