Description

  The present invention relates to an electric fishing reel provided with a drive motor that rotationally drives a spool that is rotatably supported by a reel body.

In general, when fishing for a deep fish layer such as boat fishing, an electric fishing reel (hereinafter also referred to as an electric reel) is frequently used. In this type of electric reel, a drive motor that winds and drives the spool is incorporated in the reel body, and in order to achieve a sufficient spool winding capacity of the spool and downsizing of the entire reel, for example, as shown in Patent Document 1 A configuration (spool-out type) is known in which the drive motor is housed and held in a cylindrical motor case formed between the side plates of the reel body in front of the spool instead of inside the spool.
Japanese Patent No. 3159619

  As disclosed in Patent Document 1 described above, a drive motor for a general spool-out type electric reel is unitized by accommodating a stator and an armature in a cylindrical housing. The drive motor that is unitized is accommodated and held in a cylindrical case integrally formed in front of the spool of the frame constituting the reel body.

  However, the adoption of such a motor housing structure inevitably increases the size of the cylindrical case of the frame, which necessitates a space in the vertical direction and the front-rear direction in front of the spool, and the front side of the reel body is large. It tends to become.

  In addition, the position setting that reduces the fishing line resistance (release and guidance) depends on the size of the reel body as well as being restricted by the mounting position of the level wind mechanism due to the positional relationship with the rod attachment part (detachment operation to the fishing rod). There will be cases where it will be difficult.

  The present invention has been made on the basis of the above-described problem, and is a fishing electric reel in which a drive motor is mounted between side plates on the front side of the spool. For fishing, the reel body on the front side of the spool can be shortened. An object is to provide an electric reel.

  In order to achieve the above object, an electric fishing reel according to the present invention is provided in a spool rotatably supported between side plates of a reel body and a reel body in front of the spool, and rotates the spool. A drive motor for driving, a recess having a flat portion on a part of the inner surface is formed between side plates of the reel body in front of the spool, and an armature is rotatably provided in the recess. The drive motor is configured by attaching a magnet constituting a field magnet at a position excluding the flat portion on the inner surface of the recess.

  According to the above configuration, in the drive motor disposed on the front side of the spool, the magnet constituting the field that is the component member is attached to the inner surface of the recess formed in the reel body, and The armature is disposed in the recess, and the constituent members of the reel body are part of the constituent members of the drive motor. Thereby, at least the housing part which comprises the conventional drive motor is abbreviate | omitted, and it becomes possible to miniaturize the front side of the spool of a reel main body. In this case, the recess has a flat portion on a part of the inner surface, and since the magnet is not attached to the flat portion, the recess can be made as small as possible. Thus, the front side of the spool is shortened in the vertical direction or the front-rear direction, and the reel body can be downsized to improve the holding performance and operability.

  According to the present invention, in a fishing electric reel in which a drive motor is mounted between side plates in front of the spool, the reel body on the front side of the spool can be shortened.

The pulley 16a rotates integrally with the output shaft 31, the pulley 16b rotates integrally with the spool shaft 7s, and the power transmission belt 16c wound around the pulleys 16a, 16b. The second speed reduction mechanism 17 is constituted by a known planetary gear mechanism installed between the spool shaft 7s and the spool 7, and the manual power transmission unit 18 is a drive mounted rotatably on the handle shaft 6a. A gear 18a and a pinion gear 18b meshing with the gear 18a are provided.

  A known drag mechanism 20 is disposed between the handle shaft 6a and the drive gear 18a. By rotating the drag knob 20a installed on the handle shaft 6a, a desired rotation of the spool 7 can be achieved. A braking force is applied. Further, the handle shaft 6a is provided with a reverse rotation prevention mechanism 6b, and when the drive motor 30 is driven to rotate, the manual handle 6 is prevented from interlocking rotation.

  The pinion gear 18b is rotatably disposed in an extending portion on the right side plate side of the spool shaft 7s and is movable in the axial direction, and a known clutch mechanism 22 is engaged with an outer peripheral portion thereof. . The pinion gear 18b is configured such that the clutch operating member 22a slides in the axial direction by the operation of an operation lever (not shown), whereby the pinion gear 18b is engaged / not engaged with the carrier of the second reduction gear mechanism (planetary gear mechanism). As a result, the transmission of the driving force to the spool 7 is succeeded and disengaged.

  Next, the configuration of the drive motor 30 will be described in detail.

  In the drive motor 30 according to the present invention, a recess is formed in a member constituting the reel body 5, a magnet constituting a field is attached to the inner surface of the recess, and an armature is disposed on the inside thereof. Configured. That is, the recess formed in the reel body has a function as a casing to which a magnet that generates a magnetic field that is a constituent member of the drive motor is attached.

  Specifically, in the present embodiment, a recess 32 that defines a substantially cylindrical space is formed in the front frame 3c (the reel body located on the front side of the spool 7) constituting the reel body 5. Yes. As shown in FIG. 4, the front frame 3 c forming the recess 32 has a flat portion 32 b in a part thereof (in this embodiment, the vertical direction of the reel body). In the side view, it has a circular shape whose upper and lower directions are crushed. As a result, compared with a recess formed in a circular shape, the vertical direction can be shortened.

  A magnet 33 constituting a field magnet is attached to the inner surface 32a of the recess along the circumferential direction at a position excluding the flat portion 32b. In this case, the magnet 33 may be fixed to the inner surface 32a with an adhesive or the like, or may be locked by a holding means. Further, the magnet 33 is spaced at a predetermined interval along the circumferential direction. It may be attached. The magnet 33 is provided with a yoke 33a that constitutes a magnetic circuit outside thereof to prevent leakage of magnetic force, but the frame 3c has a function as such a yoke. May be.

  The front frame 3c in which the recess 32 is formed has an opening on the right side plate side as it is, and a bottom wall 3d is formed on the left side plate side. The drive shaft is connected to the center portion of the bottom wall 3d via a bearing 34. 31 is rotatably supported.

  The drive shaft 31 is mounted with an armature 35 (having a coil 35a facing the magnet 33) which is a constituent member of the drive motor 30 so as to face the magnet 33 attached to the inner surface 32a of the recess 32. A commutator 37 that supplies current to the armature 35 is mounted on the right side plate in the axial direction of the armature 35.

  The commutator 37 protrudes from the opening on the right side plate side of the front frame 3c (opening of the recess 32), and this opening portion is fixed by a fixing screw 39 screwed to the right frame 3b in the vicinity of the front frame 3c. An end cover 40 is attached to the front frame 3c so as to be detachable. The end cover 40 is configured in advance as a single unit, and a brush 41 that flows current in contact with the commutator 37 and a brush holder 42 that holds the brush are incorporated inside the end cover 40 in the radial direction. And fixed with screws 39a. A terminal 43 is integrally incorporated in the brush holder 42 and is connected to an external power source via a lead wire 44.

  The end cover 40 includes a holding body 48 that holds a one-way clutch 46 that rotatably supports the drive shaft 31 and a bearing 47 that rotatably supports the drive shaft in order from the inner side in the axial direction. It is. In this case, the one-way clutch 46 moves the drive shaft 31 in one direction so as not to idle when the manual handle 6 is wound up and to transmit power to the spool 7 side when the drive motor is driven. It is allowed to rotate only.

  The first speed reduction mechanism 15 configured by the planetary gear mechanism described above is installed on the outer side in the axial direction with respect to the bottom wall 3d, and is closed by an end cover 50 attached to the front frame.

  In addition, a level wind mechanism 60 that winds a fishing line around the spool 7 in parallel is provided between the left and right frames 3a and 3b. The level wind mechanism 60 is disposed on the front side of the spool 7 and, as is well known, via a transmission gear mechanism (not shown) by a drive gear 18a or a gear 7d integrally formed on the side of the spool 7. A worm shaft 61 that is rotationally driven, and a fishing line guide body 65 that engages with the worm shaft 61 and is slidably driven in the left-right direction while being prevented from rotating around the shaft 62 are provided. The fishing line guide body 65 has a fishing line conduction hole 65a through which the fishing line is inserted. The fishing line is guided by the fishing line conduction hole 65a and wound around the spool 7.

  By the way, the above-described fishing line guide body 65 is a part that slides the fishing line through the fishing line conduction hole 65a and gives resistance to the fishing line, so that it can be installed at an optimal position where the fishing line resistance is reduced. preferable. As described above, in the present embodiment, since the flat portion 32 b is formed in the recess 32, a large space exists above the flat portion 32 b, and the fishing line guide body that is a constituent member of the level wind mechanism 60. 65 is installed in the position which opposes the flat part 32b above the said recess 32 used as the optimal position which reduced the fishing line resistance. Specifically, part of the constituent members of the level wind mechanism 60 (such as the shaft 62 and the fishing line guide body 65) are positioned within the range of the width W in the front-rear direction of the flat portion 32b formed in the recess 32. Is installed.

  As described above, the drive motor 30 that rotationally drives the spool 7 includes the inner surface 32a excluding the flat portion 32b of the recess 32 formed in the reel main body 5 with the magnet 33 that constitutes the field as a constituent member thereof. The armature 35 is disposed in the recess 32, and the constituent member (frame 3) of the reel body 5 is part of the constituent member (field field) of the drive motor 30. Casing).

  For this reason, the housing part which comprises the drive motor used for the conventional electric reel is abbreviate | omitted, and the reel main body 5 can be reduced in size while maintaining the output, or the size of the reel main body 5 is maintained, The armature 35 constituting the drive motor 30 can be increased in size to improve the output. Further, since the casing is integrated with the frame, a lightweight and compact electric reel can be obtained, and the operability and handling at the fishing spot can be improved. In particular, since the flat portion 32b is formed in the recess 32, the region facing the flat portion can be shortened as a whole as compared with a circular configuration, so that the size can be reduced more effectively. It becomes possible to plan.

  Further, since the flat portion 32b is formed in the recess 32, as described above, a space (a space in the vertical direction) can be effectively formed between the side plates in front of the spool. The related constituent members (at least a part of the constituent parts of the level wind mechanism 60) can be arranged in an optimum state. That is, the degree of freedom in design can be improved, for example, by installing the fishing line guide body 65 at a position where the sliding resistance of the fishing line is minimized.

  Furthermore, the conventional electric reel has a structure in which the drive motor having the housing is accommodated in a case formed in the reel body, so that it has a so-called double structure, but by adopting the structure as described above, The drive motor part has a single structure, and the area that directly contacts the outside air of the part that acts to dissipate heat (the frame part that constitutes the motor housing) can be increased, so that the heat dissipation can be improved. As a result, problems due to heat accumulation can be avoided, and the durability and winding efficiency of the drive motor can be improved. In particular, in the spool-out type electric reel as in the present invention, it is easy to configure the portion where the recess 32 serving as the housing is directly in contact with the outside air, and the heat dissipation can be further improved. It is possible to reliably prevent problems due to heat generation.

  As shown in FIG. 4, in the configuration in which the front frame 3c constituting the drive motor 30 is directly exposed, the front cover 70 may be separately attached to the front portion serving as the exposed portion. good.

  Further, in the above-described configuration, it is preferable that the seal member 52 is installed in each place on the reel body 5 so that the water tightness of the drive motor 30 can be improved. Such a seal member 52 can be constituted by, for example, an O-ring or a cover body made of a rubber-based or silicon-based material. In the present embodiment, the seal member 52 is provided between the end cover 40 and the front frame 3c, between the end cover 40 and the lead wire 44, between the end cover 50 and the front frame 3c, and between the end cover. 50 and the drive shaft 31.

  Such a seal member 52 is disposed at an appropriate position so that the inside of the recess in which the armature portion of the drive motor 30 is installed can be kept watertight, and the formation position, size, shape, and drive of the recess It is appropriately modified according to the installation mode of the constituent members of the motor.

  Next, a second embodiment of the present invention will be described with reference to FIG.

  In this embodiment, the flat portion 32b of the recess 32 formed in the front frame 3c is formed in the front-rear direction, whereby the drive motor 30 disposed on the front side of the spool 7 is moved in the front-rear direction. It is configured to be shortened.

  According to such a configuration, a space in the front-rear direction is created in front of the spool 7, and at least a part of the components of the level wind mechanism 60 is disposed in this space in the same manner as in the above-described embodiment. It becomes possible to make it a proper installation state.

  Thus, the recess 32 formed in the reel body 5 forms a flat portion 32b on the inner surface thereof, and is a portion where the magnet 33 constituting the field magnet is attached at a position excluding the flat portion. The shape and size of the recess, and the position where the flat portion 32b is formed can be appropriately modified.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the structure of above-described embodiment, A various deformation | transformation is possible. For example, the above-described driving force transmission mechanism 12 can be variously modified such as a power transmission structure using a gear train or a concentrated arrangement of driving force transmission systems on one side plate side. As for the drive motor, it is only necessary that the magnet generating the field is attached to the inner surface except for the flat portion of the recess formed in the reel body. Regarding the configuration and arrangement method of other components, It can be modified as appropriate. Moreover, about the structure of the drag mechanism 20 or the clutch mechanism 22, and its arrangement | positioning aspect, it can change suitably. In addition to the above-described frame, the portion forming the recess may be formed integrally with the outer plate, or may be formed over the frame 3 and the outer plate 4.
