Description

  The present invention relates to a motor used for a fishing reel.

  2. Description of the Related Art Conventionally, some fishing reels include a drive component that is electrically driven. In such a fishing reel, a motor for driving the drive component is incorporated.

  For example, in a fishing electric reel (hereinafter also referred to as an electric reel) that winds and drives a spool as a driving component, a motor for rotating the spool is incorporated in the reel body.

  Such a motor is generally provided with a yoke (magnetic-shielding ring) that has an armature disposed inside a magnet that constitutes a field, and a yoke that forms a magnetic circuit outside the magnet to prevent magnetic leakage. (See, for example, Patent Document 1), for example, a cylindrical motor case that is accommodated in the inner space of the spool (so-called spool-in type) or formed between the side plates of the reel body in front of the spool. Housed inside (so-called spool-out type).

  By the way, the yoke disposed on the outer periphery of the magnet generally has a cylindrical shape with a circular cross section, but the cross section has a different shape from a circular shape such as a drum shape for the purpose of downsizing the reel. In any case, it is integrally formed in a cylindrical shape as a whole.

Japanese Patent Laid-Open No. 2003-134776

  As described above, when the yoke is integrally formed in a cylindrical shape, a yoke having a long dimension (or a wide width) is formed (generally, forming by pultrusion molding, pipe molding, or the like). It is technically difficult, and there is a limit to the high thickness of the magnetic shield, which is expensive. Further, it becomes difficult to form the yoke into a deformed cross section such as a drum shape for the purpose as described above. In other words, it is difficult to make the yoke integrally formed in a cylindrical shape long and thick, or to have a deformed cross section, and if such a form is obtained, the manufacturing cost increases. .

  The present invention has been made by paying attention to the above-described problems, and provides a fishing reel motor with an inexpensive yoke with a high degree of design freedom that can be easily formed in various lengths, thicknesses, and cross-sectional shapes. The purpose is to do.

  In order to achieve the above-described object, the present invention provides a fishing reel motor for driving a fishing reel drive component, comprising a magnet constituting a field and an inner side of the magnet. And a cylindrical yoke that is attached to the outside of the magnet and forms a magnetic circuit to prevent leakage of magnetic force, and the yoke includes a plurality of yoke segments divided in the circumferential direction. The yoke segments are combined and formed into a cylindrical shape.

  According to the above configuration, the cylindrical yoke for preventing leakage of magnetic force is formed of a plurality of yoke segments divided in the circumferential direction, and these yoke segments are combined to form a cylindrical shape. It can be easily formed in a long length, a thick wall, and a cross-sectional shape. In other words, when the yoke is integrally formed as a cylindrical single body, it is technically difficult to form a yoke having a long dimension (or a wide width), and the thickness is made to be a high-thickness dimension that is expensive in terms of magnetic shielding. However, it is difficult to mold the yoke into an irregular cross section such as a drum shape, but the yoke is formed in a cylindrical shape by combining a plurality of yoke segments divided in the circumferential direction as in the above configuration. Then, each yoke segment itself can be easily formed in various shapes, lengths, and thicknesses by pressing, deep drawing, etc., so the yokes can be formed in various lengths, thicknesses, and cross-sectional shapes by combining these yoke segments. It becomes easy to form. Therefore, a fishing reel motor with an inexpensive yoke having a high degree of design freedom can be realized.

  According to the fishing reel of the present invention, the cylindrical yoke for preventing the leakage of magnetic force is composed of a plurality of yoke segments divided in the circumferential direction, and these yoke segments are combined to form a cylindrical shape. Therefore, it is possible to realize an inexpensive yoke with a high degree of design freedom that can be easily formed in various lengths, thicknesses, and cross-sectional shapes.

  A rotational drive force from the manual handle 6 and the drive motor 30 is input to the spool 7 via the drive power transmission mechanism 12. Hereinafter, a schematic configuration of the driving force transmission mechanism 12 will be described.

  The driving force transmission mechanism 12 of the present embodiment is configured to be distributed to the left frame 3a and the right frame 3b, and on the left frame 3a side, a first reduction mechanism 15 that decelerates the output of the drive motor 30, An electric power transmission unit 16 that transmits the rotational driving force decelerated by the first reduction mechanism 15 to the spool shaft 7s is provided. Further, on the right frame 3b side, the second reduction mechanism 17 that decelerates the rotational driving force of the spool shaft 7s and transmits it to the spool 7, and the rotational driving force of the driving shaft (handle shaft) 6a of the manual handle 6 are the first. A manual power transmission unit 18 that transmits to the spool 7 via the two speed reduction mechanism 17 is provided.

  In this case, the first speed reduction mechanism 15 is configured by a known planetary gear mechanism that is installed between the output shaft (drive shaft) 31 of the drive motor 30 and the front frame 3c, and the electric power transmission unit 16 includes the output shaft The pulley 16a rotates integrally with the pulley 31, the pulley 16b rotates integrally with the spool shaft 7s, and the power transmission belt 16c wound around the pulleys 16a and 16b.

  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, the spool 7 can be controlled in a desired manner. Power 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 the 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 the outer peripheral portion thereof. The pinion gear 18b can be engaged / disengaged with the carrier of the second reduction gear mechanism (planetary gear mechanism) when the clutch operating member 22a slides in the axial direction by operation of an operation lever (not shown). As a result, transmission of the driving force to the spool 7 is succeeded and disengaged.

  As shown in FIG. 2, a level wind mechanism 60 that winds a fishing line around the spool 7 in parallel is provided between the left and right frames 3 a and 3 b. 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 formed integrally with the side portion of the spool 7.

The fishing line is guided by the fishing line conduction hole 65a and wound around the spool 7.

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

  For example, the drive motor 30 according to the present embodiment forms a recess in a member constituting the reel body 5 and is accommodated in the recess. Specifically, in the present embodiment, as clearly shown in FIG. 2, the front frame 3 c constituting the reel body 5 (between the side plates of the reel body located on the front side of the spool 7) is substantially cylindrical ( A recess 32 defining a space having a substantially circular cross section is formed, and the drive motor 30 is fitted and mounted in the recess 32. That is, the recess 32 formed in the reel body 5 has a function as a casing for attaching the drive motor 30.

  As clearly shown in FIGS. 2 and 3, the drive motor 30 disposed in the recess 32 of the front frame 3 c is opposed to the cylindrical magnet 33 constituting the field and the inside of the magnet 33. An armature 35 (having a coil 35a facing the magnet 33) that is disposed and mounted on the drive shaft 31 of the motor and is fitted and attached to the outside of the magnet 33 to form a magnetic circuit to form a magnetic force And a cylindrical yoke 90 (a yoke; iron containing carbon). Here, the magnet 33 is fixed to the inner surface of the yoke 90 by, for example, an adhesive. In this embodiment, the yoke 90 is formed separately from the front frame 3c, but the front frame 3c may also serve as the yoke.

  In the present embodiment, the yoke 90 is composed of a plurality of yoke segments 90A and 90B divided in the circumferential direction, and these yoke segments 90A and 90B are combined to form a cylinder (see FIGS. 2 and 3). ). In this embodiment, two semicircular yoke segments 90A and 90B having a predetermined thickness are joined by bonding or the like to form a cylindrical yoke 90. The number of divisions in the circumferential direction of the yoke 90, that is, the yoke segment The number is not limited to two, and can be arbitrarily set to three, four, and the like. In the structure in which the drive motor 30 is mounted in the reel body 5 (in the recess 32) as in the present embodiment, it is possible to realize the effect of preventing magnetic leakage by joining the yoke segments together in a cylindrical shape by bonding or the like. Although relatively easy, it is preferable to minimize the number of divisions of the yoke 90 in order to ensure the effect of preventing magnetic leakage.

  The front frame 3c forming the recess 32 has an opening on the right side plate 4b as it is, and a bottom wall 3d formed on the left side plate 4a side. The drive shaft 31 is rotatably supported. 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 3c. Yes.

  Here, a commutator 37 for supplying a current to the armature 35 is attached to the right side plate in the axial direction of the armature 35 attached to the drive shaft 31.

  This 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 as a single unit in advance, and a brush 41 that flows current in contact with the commutator 37 and a brush holder 42 that holds the brush 41 are incorporated inside the end cover 40 in the radial direction. And fixed with screws. A terminal 43 is integrally incorporated in the brush holder 42, and the terminal 43 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 30 is driven. It is allowed to rotate only.

  As described above, according to the present embodiment, the cylindrical yoke 90 that prevents leakage of magnetic force includes the plurality of yoke segments 90A and 90B divided in the circumferential direction, and these yoke segments 90A and 90B. Therefore, the yoke 90 can be easily formed in various lengths, thicknesses, and cross-sectional shapes. That is, when the yoke 90 is integrally formed as a cylindrical single body, it is technically difficult to form a yoke having a long dimension (or a wide width), and the thickness is high and the magnetic shield is expensive. However, it is difficult to form the yoke 90 into an irregular cross section such as a drum shape (see the second embodiment described later), but a plurality of yokes divided in the circumferential direction as in this embodiment. If the yoke 90 is formed in a cylindrical shape by combining the segments 90A and 90B, the yoke segments 90A and 90B themselves can be easily formed in various shapes, lengths, and thicknesses by pressing, deep drawing, or the like. The combination of these yoke segments 90A and 90B makes it easy to form the yoke 90 in various lengths, thicknesses, and cross-sectional shapes. Therefore, the fishing reel drive motor 30 with an inexpensive yoke 90 with a high degree of design freedom can be realized.

  In the configuration described above, it is preferable that seal members 52 (see FIG. 1) are 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.

  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.

  FIG. 4 shows a second embodiment of the present invention. As shown in the drawing, in this embodiment, the front frame 3c forming the recess 32 for accommodating the drive motor 30A has a flat portion 32b on a part thereof (in the vertical direction of the reel body 5 in this embodiment). Thus, the recess 32 has a circular shape whose upper and lower directions are crushed in a side view. As a result, as compared with the recess formed in a circular shape as in the first embodiment, the vertical shortening can be achieved.

  In addition, along with the formation of the flat portion 32b of the recess 32, the upper and lower portions of the outer periphery of the yoke 90 of the drive motor 30A fitted in the recess 32 correspond to the position of the flat portion 32b. A flat portion 91 is formed on the surface. Also in the present embodiment, the yoke 90 is composed of a plurality of yoke segments 90A and 90B divided in the circumferential direction, and these yoke segments 90A and 90B are combined to be formed into a cylindrical shape. It is possible to easily form a cross section having an irregular shape other than a circular shape having

  Further, in the drive motor 30A of this embodiment with the yoke 90 having the flat portion 91, the magnet 33 constituting the field is attached to the inner surface of the yoke 90 along the circumferential direction at a position excluding the flat portion 91. Yes. In this case, the magnet 33 may be fixed to the inner surface of the yoke 90 by an adhesive or the like, or may be locked by a holding means. Furthermore, the magnet 33 is spaced at a predetermined interval along the circumferential direction. It may be attached. In the configuration in which the magnet 33 is divided into two parts as in the present embodiment, the divided part of the yoke 90 (joint part between the yoke segment 90A and the yoke segment 90B) is arranged in the vicinity of the center part in the circumferential direction of each magnet 33. It is preferable to be located at.

  As described above, also in the present embodiment, the yoke 90 is composed of a plurality of yoke segments 90A and 90B divided in the circumferential direction, and these yoke segments 90A and 90B are combined to form a cylindrical shape. The same effects as those of the first embodiment can be obtained, and the flat portions 32b and 91 are formed in the recess 32 and the yoke 90. Therefore, the regions facing the flat portions 32b and 91 are circular. As a whole, it can be shortened as compared with the configuration, and it becomes possible to achieve a more compact size.

  Further, by forming the flat portion 32b in the recess 32, a space (a space in the vertical direction) can be effectively formed between the side plates 4a and 4b in front of the spool 7, and this space is used, The related constituent members can be arranged in an optimum state. That is, for example, as shown in FIG. 4, at least a part of the components of the level wind mechanism 60, specifically, the fishing line guide body 65 is placed at a position where the sliding resistance of the fishing line is minimized (the upper side of the recess 32. The degree of freedom in design can be improved, for example, by being installed at a position facing the flat portion 32b.

  FIG. 5 shows a third embodiment of the present invention. In the above-described embodiment, the drive motor 30 is disposed on the front side of the spool 7 of the reel body 5, but in the present embodiment, the drive motor 30 is installed inside the spool 7 ( So-called spool-in type).
