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. This type of electric reel incorporates a so-called spool-in type in which a drive motor for winding and driving the spool is incorporated in the reel body, and the drive motor is housed in the internal space of the spool, and the drive motor is mounted on the reel body in front of the spool. A so-called spool-out type, which is accommodated in a cylindrical motor case formed between side plates, is known.

  In any type of electric reel, the drive motor has a configuration in which a stator and an armature are accommodated in a cylindrical motor housing. The drive motor unitized in this way is a motor provided in the reel body. Housed in a case.

  By the way, such electric reels can handle winding operations for relatively shallow fish layers and motor failures without any problems, in addition to the electric winding drive mainly for deep fish layers. The manual-use type electric fishing reel that can be wound up with a manual handle is the mainstream.

As disclosed in Patent Literature 1 and Patent Literature 2, the power transmission system of this manual combined type electric fishing reel is configured to spool one-way rotation (forward rotation) of the motor via a speed reduction mechanism including a planetary gear. In addition, the rotation of the motor rotating shaft in the other direction (reverse rotation) is blocked by a rolling one-way clutch in order to transmit the handle rotation during manual winding operation to the spool.
No. 7-46150 Registered Utility Model No. 2586330

  Such a rolling one-way clutch for controlling the rotation of a motor is generally provided between an end portion of a motor rotation shaft and a support portion fixed to a reel body different from the motor housing. Therefore, the concentricity between the end of the motor rotation shaft and the support portion of the reel body is difficult to obtain with high accuracy, and the high-speed rotation of the motor rotation shaft also affects the durability of the rolling one-way clutch. However, there is a problem that the wedge action acting on the roller of the one-way clutch at the time of manual winding drive is hindered.

  Further, in the conventional drive motor structure described above, the end of the motor rotating shaft that is supported by the bearing in the motor housing and protrudes in the axial direction is fitted into a rolling one-way clutch provided on the support portion fixed to the reel body. In addition, since the one-way rotation mechanism of the motor rotation shaft is configured, the length of the motor rotation shaft becomes long, and there is a limit to the miniaturization of the whole electric reel for manual use type fishing. It is left.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is to obtain a concentricity with respect to the one-way clutch of the rotation shaft of the drive motor with high accuracy and to rotate the drive motor. An object of the present invention is to provide an electric fishing reel suitable for downsizing that can reduce the length of the shaft.

  In order to achieve the above-described object, the present invention provides a fishing electric motor having a spool that is rotatably supported between side plates of a reel body, and a drive motor that is provided on the reel body and rotationally drives the spool. In the reel, a recess is formed in the reel body, an armature is rotatably provided in the recess, and a magnet constituting a field is attached to the inner surface of the recess facing the armature. A drive motor for rotating the spool is configured, and the opening of the recess is covered with a cover body, and the cover body rotatably supports the motor rotating shaft on which the armature is mounted. And a one-way clutch that allows rotation in one direction and prevents rotation in the other direction.

  According to the above configuration, since the bearing supporting the motor rotation shaft and the one-way clutch are held inside the cover body that covers the opening of the recess, the bearing is positioned in the motor housing as in the past. Compared to the structure in which the one-way clutch is positioned outside the motor housing, the bearing and the one-way clutch are close to each other, and the motor rotation shaft is supported in the vicinity of the one-way clutch coaxially therewith. The concentricity with respect to the one-way clutch of the motor rotation shaft can be obtained with high accuracy. That is, the wedge action of the one-way clutch (the wedge action acting on the roller) at a position where the concentricity of the motor rotation shaft can be obtained with high accuracy is possible. As a result, it is possible to obtain a wedge action that is reliable and free of trouble during manual winding operation, and the durability of the one-way clutch is also improved.

  In the above configuration, the drive motor is not incorporated in the reel body as an integral unit as in the prior art, but individual parts constituting the drive motor are arranged in the recesses of the reel body. The reel body has a structure that also serves as a motor housing, and the one-way clutch is held inside the cover body that covers the opening of the recess, so that the one-way clutch is built in the motor housing of the conventional drive motor. Therefore, it is not necessary to extend the motor rotation shaft to the outside of the motor housing as in the prior art. For this reason, the length of the motor rotation shaft can be shortened to reduce the size of the entire reel.

  In addition, when the individual parts constituting the drive motor are arranged in the recesses of the reel body as in the above configuration, so that the reel body also serves as a motor housing, at least a conventional drive motor is constructed. Therefore, the reel body can be downsized while maintaining the output, or the output of the drive motor can be improved while maintaining the size of the reel body.

  The recess formed in the reel body described above is a portion to which a magnet constituting a field magnet is attached on the inner surface, and the shape, size, and installation location can be appropriately modified. is there. In the above configuration, the one-way clutch is preferably disposed closer to the armature side than the bearing. If it does in this way, the concentricity with respect to the one-way clutch of a motor rotating shaft can further be raised.

  ADVANTAGE OF THE INVENTION According to this invention, the concentricity with respect to the one-way clutch of the rotating shaft of a drive motor can be obtained with high precision, and the length of the rotating shaft of a drive motor can be shortened. Electric reels can be provided.

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 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, A magnet 33 constituting a field is attached to the inner surface 32a along the circumferential direction. 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. Further, the magnet 33 has a cylindrical yoke (a yoke) 33a that forms a magnetic circuit on its outer side to prevent leakage of magnetic force, and functions as such a yoke on the frame 3c. May be given.

  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, and the drive shaft 31 is interposed via a bearing 34 at the center of the bottom wall 3d. Is supported rotatably.

  The drive shaft 31 is mounted with an armature 35 (coil facing the magnet 33), which is a constituent member of the drive motor 30, facing 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 side of the armature 35 in the axial direction.

  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 as a cover body 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.

  In addition, the end cover 40 has 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 31 in order from the inner side in the axial direction. It has been incorporated. 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. Only in the drive shaft 31 (allowing rotation in one direction and preventing rotation in the other direction). In particular, in this embodiment, it is arranged closer to the armature 35 side than the bearing 47. It is installed.

  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.

  As described above, in the present embodiment, the bearing 47 and the one-way clutch 46 that support the drive shaft (motor rotating shaft) 31 are held inside the end cover 40 that covers the opening of the recess 32. Therefore, the bearing 47 and the one-way clutch 46 are close to each other and the drive shaft 31 is only one in comparison with the conventional structure in which the bearing is located in the motor housing and the one-way clutch is located outside the motor housing. The bearing is coaxially supported in the vicinity of the direction clutch 46, and the concentricity of the drive shaft 31 with respect to the one-way clutch 46 can be obtained with high accuracy. That is, the wedge action of the one-way clutch 46 (the wedge action acting on the roller) at a position where the concentricity of the drive shaft 31 can be obtained with high accuracy is possible. As a result, a wedge action that is reliable and free of trouble during manual winding driving can be obtained, and the durability of the one-way clutch 46 is improved.

  In the above configuration, the drive motor is not integrated into the reel body as an integral unit as in the prior art, but the individual parts 33 and 35 constituting the drive motor 30 are placed in the recess 32 of the reel body 5. By arranging the reel body 5 to serve as a motor housing, the one-way clutch 46 is held inside the end cover 40 that covers the opening of the recess 32, so that the motor of the conventional drive motor is provided. Since the same configuration as that in which the one-way clutch 46 is built in the housing is realized, it is not necessary to extend the drive shaft 31 to the outside of the motor housing as in the prior art. Therefore, the length of the drive shaft 31 can be shortened to reduce the size of the entire reel.

  Further, in the above-described configuration, the drive motor 30 that rotationally drives the spool 7 has a magnet 33 that constitutes a field that is a constituent member thereof attached to the inner surface of the recess 32 formed in the reel body 5, In addition, 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 of the drive motor 30 (casing that generates a field). However, this makes it possible to omit the housing portion that constitutes the drive motor used in the conventional electric reel, and the reel body 5 can be reduced in size while maintaining the output, or the reel body. While maintaining the size of 5, the armature 35 constituting the drive motor 30 can be enlarged 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 addition, the conventional electric reel has a so-called dual structure because the drive motor having the housing is housed in a case formed in the reel body. However, 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, it becomes easy to configure the portion where the recess that becomes the housing is directly in contact with the outside air, and it is possible to improve the heat dissipation and to ensure the trouble due to heat generation. It becomes possible to prevent.

  In addition, the above-mentioned recess 32 should just be a part in which the magnet 33 which comprises a field magnet is attached to the inner surface, About the shape, a magnitude | size, and an installation location, it can change suitably. It is. 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.

  In the above-described configuration, it is preferable that the seal member 52 is installed in various places 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.

Further, the magnet 33 may have a yoke (yoke) constituting a magnetic circuit attached to the outside thereof, or the protruding portion 3e may have a function as such a yoke.

  The protrusion 3e in which the recess 32 is formed has an opening on the left side plate as it is, and a bottom wall 3f is formed on the right side plate side, and a drive motor 30 via a bearing 34 at the center of the bottom wall 3f. The drive shaft 31 is rotatably supported.

  The drive shaft 31 is mounted with an armature 35 (coil facing the magnet 33), which is a constituent member of the drive motor 30, facing 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 outer side in the axial direction of the armature 35. In the left frame 3a on which the protruding portion 3e is formed, a brush 41 that flows in contact with the commutator 37 and a brush holder 42 that holds the brush are incorporated and fixed by 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.
