Description

[Technical field]

[0001] The present invention relates to an electric fishing reel that winds a fishing line onto a spool using the output from a drive motor supported on a reel body. [Background technology]

[0002] Typically, electric fishing reels are structured to rotate a spool by driving a drive motor supported on a frame of a reel body to wind up a fishing line, as disclosed in Patent Document 1, for example. The output from the drive motor is reduced through a reduction mechanism such as a planetary gear mechanism and transmitted to the drive shaft of the spool. The drive motor is housed in a motor case supported on a frame, and a set plate that supports the planetary gear mechanism, bearing parts, etc. that constitute the reduction mechanism is attached to the frame.

[0003] [Patent Document 1] Patent Publication No. 2007-252330 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, electric fishing reels have been made smaller so that they can be operated by hand, and it is preferable not to reduce the output of the drive motor as much as possible. However, in conventional electric fishing reels, as described above, the set plate is attached to the motor case supported by the frame, which increases the cumulative tolerance (the tolerances from the motor case to the frame and from the frame to the set plate are cumulative), making it difficult to bring out the coaxial shaft. Therefore, the output of the drive motor is likely to decrease to the extent that the coaxial shaft cannot be brought out.

[0005] The present invention has been made in view of the above-mentioned problems, and has an object to provide an electric fishing reel in which a drop in output from the drive motor is less likely to occur. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the electric fishing reel of the present invention is equipped with a drive motor that is mounted on a frame of a reel body and rotates a spool around which fishing line is wound, and is characterized in having a motor case that houses motor components of the drive motor and is attached to the frame, a set plate that is attached to the frame, and a fitting structure that fits the motor case into the set plate.

[0007] In the electric fishing reel described above, by fitting the motor case to the set plate, it is possible to reduce the cumulative tolerance. In other words, if the tolerance is large, the efficiency of transmitting the driving force will decrease, for example, because parts such as bearings become slightly eccentric with respect to the output shaft of the drive motor, but by integrating the motor case and the set plate with a fitting structure as described above, it becomes easier to achieve a coaxial relationship between the output shaft of the drive motor and the reduction mechanism and bearing parts, etc., disposed on the set plate, and it is possible to suppress a decrease in the output of the drive motor when transmitting the driving force. Effect of the Invention

[0008] According to the present invention, an electric fishing reel is obtained in which a drop in output from a drive motor is less likely to occur. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An embodiment of an electric fishing reel according to the present invention will be described below with reference to Figures 1 to 8. In the following description, the front-rear direction, left-right direction, and up-down direction are defined as the directions shown in Figure 1, the front-rear direction is defined as the axial direction of the fishing rod when the fishing rod is attached, the left-right direction is defined as the axial direction of the output shaft of the drive motor, and the up-down direction is defined as the direction perpendicular to the front-rear direction and the left-right direction.

[0011] As shown in Figures 1 to 5, an electric fishing reel 1 according to this embodiment has a reel body 5 equipped with left and right side plates 5A, 5B formed by attaching left and right covers 4a, 4b to left and right frames 3a, 3b. The left and right frames 3a, 3b are connected in the left-right direction to form an integrated structure as shown in Figures 2 and 3 (the integrated structure is also referred to as frame 3).

[0012] A manual handle 6 for winding is provided on one of the side plates (right side plate 5B) constituting the reel body 5, and a spool 7 around which the fishing line is wound is rotatably supported between the left and right side plates 5A, 5B. In this embodiment, a drive motor 8 is held between the left and right frames 3a, 3b on the front side of the spool 7 (FIGS. 2 to 5). The spool 7 is rotated in the fishing line winding direction by the winding operation of the manual handle 6 and the rotational drive of the drive motor 8. Incidentally, the drive motor 8 may be configured to be installed inside the spool 7, but by installing it in front of the spool 7 as in this embodiment, it is possible to make the reel body 5 as compact as possible while ensuring the amount of line wound on the spool 7.

[0013] A box-shaped control case 10 that houses a control unit that controls the drive motor 8 is disposed above the spool 7 between the left and right side plates 5A, 5B. An operating member 12 that adjusts the output of the drive motor 8 is disposed in the rear portion of the control case 10. The operating member 12 in this embodiment is in the form of a dial provided on a support shaft that is rotatably supported at the rear of the control case 15, and is configured so that the output of the drive motor can be adjusted by rotating the operating member 12 in the front-rear direction.

[0014] Further, a known clutch mechanism 17 (FIGS. 2 and 3) for switching the spool 7 between a fishing line winding state and a free rotation state is disposed on the frame 3 (right frame 3b in this embodiment). This clutch mechanism 17 has a function of connecting and disconnecting the power transmission from the manual handle 6 and the drive motor 8 to the spool 7, and is configured to switch from the clutch ON state to the clutch OFF state with a clutch operating member 18 disposed on the rear side of the spool 7 so as to be displaceable in the up and down direction. That is, when the clutch operating member 18 is pressed down in the clutch ON state (power transmission state) shown in FIG. 1, the clutch is switched to the clutch OFF state.

[0015] Incidentally, the return from the clutch-off state to the clutch-on state can be performed automatically by winding the manual handle 6, driving the drive motor 8, or the like.

[0016] A set plate 20, which will be described later, is disposed between the right frame 3b and the right cover 4b. An engagement hole 22 is formed on the rear end side of the set plate 20, and the engagement hole 22 is fitted into a protrusion 3d formed on the right frame 3b to perform identification, and in this state, a plurality of screws 23a to 23d are screwed from the outside into screw holes (which may be screw holes formed in bosses) 3f to 3i formed in the right frame 3b, thereby preventing the set plate from rotating and fixing it to the right frame 3b.

[0017] Next, the configurations of the drive motor 8 and the set plate 20 will be described with reference to FIGS. As is well known, the drive motor 8 includes motor components such as a magnet that forms a field magnet along the circumferential direction, an armature with a coil wound so as to face the magnet, and a commutator attached to the end of the output shaft 8a, and these motor components are housed inside the radial direction of a motor case 8A formed in a substantially cylindrical shape. The output from the output shaft 8a of the drive motor 8 is reduced in speed by a reduction mechanism 30 installed on the right frame side, and transmitted to the spool 7 via a power transmission mechanism 40.

[0018] The set plate 20 accommodates the reduction gear mechanism 30 on the right frame side, and supports the gears 41, 42 and bearing parts 50 that constitute the power transmission mechanism 40. That is, the set plate 20 of this embodiment includes an accommodation portion 20A that accommodates the reduction gear mechanism 30 provided on the output shaft 8a of the drive motor 8, and a gear support portion 20B that supports the gears 41, 42 that constitute the power transmission mechanism.

[0019] The motor case 8A is open on both axial sides, with the right frame side closed by a set plate 20 and the left frame side closed by a lid member 26 fixed to the left frame 3a. The output from the output shaft 8a of the drive motor 8 is reduced in speed reduction mechanism 30 installed on the right frame side and transmitted to the spool 7 via a power transmission mechanism 40.

[0020] Moreover, the motor case 8A is not formed integrally with the frame 3, but is formed into a cylindrical shape as a separate member from the frame, using a material such as a metal, such as aluminum, titanium, or magnesium, a resin, or FRP. In other words, it can be formed from a material different from that of the frame 3, and the above-mentioned output shaft 8a and motor components such as a magnet, an armature, and a commutator are mounted inside such a motor case.

[0021] The housing portion 20A is formed in a substantially cylindrical shape bulging in the axial direction with respect to the gear support portion 20B, and the reduction mechanism 30 is housed in its internal space. As is well known, the reduction mechanism 30 of this embodiment includes a planetary gear mechanism (two stages) attached to the output shaft 8a of the drive motor 8, and includes sun gears 31a and 31b attached to the output shaft 8a, planetary gears 32a and 32b meshing with the sun gears 31a and 31b, and an internal gear 33 having internal teeth 33a meshing with the planetary gears 32a and 32b. External teeth 33b are formed on the outer circumferential surface of the internal gear 33, and the rotational drive reduced by the reduction mechanism 30 is output to gears 41 and 42 constituting the power transmission mechanism 40 via the external teeth 33b.

[0022] Normally, the side plate (the cover) is an exterior component and is often constructed with curved surfaces, so the reduction gear mechanism 30 and the power transmission mechanism 40 cannot be fixed and positioned appropriately using only the side plate. In contrast, by providing the set plate 20 as described above, the reduction gear mechanism 30 and the power transmission mechanism 40 can be positioned appropriately, and ease of installation and maintenance can be improved. In addition, by providing the set plate 20 with a bulging housing portion 20A that houses the reduction gear mechanism 30, the width direction of the reel body can be made more compact.

[0023] The motor case 8A and the set plate 20 have a fitting structure for fitting the motor case 8A into the set plate 20. That is, in the present invention, the motor case 8A is configured to be fitted into the set plate 20, rather than supporting the motor case on a frame and fixing the set plate to the frame as in the conventional case.

[0024] In this way, by fitting the motor case 8A to the set plate 20, it is possible to reduce the cumulative tolerance from the motor case to the frame and from the frame to the set plate, which was previously the case, and it becomes easier to achieve a coaxial connection between the output shaft 8a of the drive motor 8 and the reduction mechanism 30, bearing parts, etc., making it possible to suppress a reduction in motor output.

[0025] In the fitting structure in this embodiment, a convex portion 8b is formed on the motor case 8A side, and a concave portion 20b into which the convex portion 8b can be fitted is formed on the set plate 20 side. In this case, since the motor case 8A is configured in a cylindrical shape with a cross section having a substantially circular shape centered on the output shaft 8a, the convex portion 8b is formed in an annular shape with the outer end edge having the maximum diameter extending in the axial direction. In addition, the concave portion 20b on the set plate 20 side is configured as an annular groove extending in the axial direction on the inner surface of the inner tip edge portion so that the accommodating portion 20A is formed in a similar circular shape and the annularly formed convex portion 8b can be fitted therein.

[0026] Specifically, the fitting structure of this embodiment is composed of the outer peripheral surface of an annular convex portion 8b and the inner peripheral surface of an annular concave portion 20b, and both the convex portion 8b and the concave portion 20b are configured in a circular shape centered on the output shaft 8a of the drive motor 8.

[0027] According to such a circular fitting structure, the orbit of the reduction mechanism 30 such as a planetary gear connected to the output shaft 8a becomes circular, so that it is possible to realize a fitting structure that ensures the minimum space required for rotation. Also, by making the fitting portion an annular convex portion formed on the radially outer end of the end of the motor case 8A, it becomes easy to install it into the concave portion 20b, and since it fits at the position of maximum diameter, a stable fixed state without rattling can be obtained.

[0028] In this embodiment, since an internal gear 33 that outputs power to the outside is arranged inside the storage section 20A, an arc-shaped cutout portion 20d is formed on the outer circumferential surface of the storage section 20A so that the external teeth 33b can mesh with the gear 41 (Figures 6 and 7).

[0029] Further, in this embodiment, the protrusion 8b formed on the motor case 8A serves as an assembly mark for positioning the set plate 20 attached to the frame 3. As shown in FIG. In this way, by making the motor case 8A also function as the assembly mark for positioning the set plate 20 relative to the frame 3, there is no need to provide a separate boss or the like to position the set plate 20 on the frame 3, and the internal structure can be simplified to make it smaller and lighter.

[0030] As described above, in this embodiment, the protrusions 8b of the motor case 8A serve as proof of assembly of the set plate 20 to the frame 3. In such a configuration, it is preferable to further configure the motor case 8A so that it can be stably fixed to the frame 3. For example, by forming two arc-shaped protrusions 8e along the circumferential direction on the outer circumferential surface of the motor case 8A and spaced apart in the axial direction, and forming grooves 3e in the frame 3 into which the protrusions 8e fit, it becomes possible to stably hold the motor case 8A on the frame 3.

[0031] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. The fitting structure between the motor case 8A and the set plate 20 may be a structure other than the annular protrusion 8b and the annular recess 20b having the notch 20d, such as a simple recess-protrusion fit. Also, a structure in which a recess is formed on the motor case side and a protrusion is formed on the set plate side, or a structure in which the inner peripheral surface of the protrusion 8b of the motor case 8A fits into the outer peripheral surface of the accommodation portion 20A of the set plate 20 may be used.

[0032] Moreover, the power transmission mechanism 40 supported by the set plate 20 can be modified in various ways, for example by transmitting power by a transmission belt, etc., so long as it has the function of transmitting the rotational driving force of the drive motor 8 to the spool 7 side. The set plate 20 and the manual handle 6 may be disposed on the left side plate side. Furthermore, the clutch mechanism can also be modified in various ways. [Explanation of symbols]
