Description

Technical Field

[0001] The present invention relates to an electric fishing reel for winding a fishing line onto a spool by output from a driving motor supported on a reel body. Background Art

[0002] Generally, as disclosed in Patent Document 1, the structure of an electric fishing reel is such that a driving reel is rotated and a fishing line is wound up by driving a driving motor supported on a frame of the reel body. The output from the driving motor is decelerated by a speed reduction mechanism such as a planetary gear mechanism and transmitted to the driving shaft of the reel.

[0003] Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2007-252330 Summary of the invention

[0004] Recently, electric fishing reels are being miniaturized to enable handheld operation, but it is preferred to minimize the output of the drive motor. However, as described above, since conventional electric fishing reels have a mounting plate mounted on a motor housing supported on a frame, there is a problem that the cumulative tolerance during assembly increases (accumulated tolerances from the motor housing to the frame, and from the frame to the mounting plate), and the transmission efficiency of the motor drive force decreases due to a decrease in coaxiality.

[0005] The present invention has been made in view of the above-mentioned problems, and the technical problem to be solved is to provide an electric fishing reel that can suppress a reduction in the output of a driving motor.

[0006] In order to achieve the above-mentioned object, the electric fishing reel of the present invention is an electric fishing reel having a drive motor for rotationally driving a reel around which a fishing line is wound, and is characterized in that: The invention comprises: a frame constituting a main body of the cable reel; a motor housing accommodating motor components of the driving motor; and a mounting plate mounted on the frame. The mounting plate contains power transmission parts including a speed reduction mechanism. The motor housing and the mounting plate are respectively composed of separate parts. One axial end of the motor housing is supported on the frame, and the other axial end is supported on the mounting plate. The motor housing and the mounting plate are engaged with each other through an engaging structure.

[0007] According to the above-mentioned electric fishing reel, by using the interlocking structure to interlock the motor housing and the mounting plate, the accumulated tolerance during assembly can be reduced. That is, when the tolerance is large, parts such as bearings will be slightly eccentric relative to the output shaft of the drive motor, which will cause the transmission efficiency of the drive force to decrease. However, according to the present invention, by using the interlocking structure to integrate the motor housing and the mounting plate, the coaxiality between the output shaft of the drive motor and the power transmission parts including the speed reduction mechanism accommodated in the mounting plate can be improved, and when transmitting the motor driving force, the decrease in the output of the drive motor can be suppressed.

[0008] As described above, according to the present invention, an electric fishing reel capable of suppressing a decrease in the output of a drive motor can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] Below, refer to Figures 1 to 8 An embodiment of the electric fishing reel according to the present invention is described. Figure 1The directions described are used to define the front-to-back direction, left-to-right direction, and up-down direction. The front-to-back direction is defined by the axial direction of the fishing rod when the fishing rod is installed, the left-to-right direction is defined by the axial direction of the output shaft of the driving motor, and the up-down direction is defined by the direction orthogonal to the front-to-back direction and left-to-right direction.

[0011] like Figures 1 to 5 As shown, the electric fishing reel 1 according to the present embodiment includes a reel body 5, which includes a left side plate 5A and a right side plate 5B formed by attaching a left cover 4a and a right cover 4b to a left frame 3a and a right frame 3b. Figures 2 to 3 As shown, the left frame 3a and the right frame 3b are connected to form an integrated structure (the integrated structure is also referred to as the frame 3).

[0012] A manual handle 6 for winding up is provided on one side plate (right side plate 5B) constituting the reel body 5, and a reel 7 for winding up the fishing line is rotatably supported between the left side plate 5A and the right side plate 5B. In the present embodiment, a drive motor 8 is held between the left frame 3a and the right frame 3b on the front side of the reel 7 ( Figures 2 to 5 ) By the winding operation of the manual handle 6 and the rotational drive of the drive motor 8, the reel 7 is rotationally driven in the fishing line winding direction. The drive motor 8 may be arranged inside the winding drum 7, but by arranging it in front of the winding drum 7 as in the present embodiment, the winding amount of the winding drum 7 can be ensured and the reel body 5 can be made as compact as possible.

[0013] A box-shaped control box 10 for accommodating a control unit for controlling the drive motor 8 is disposed above the reel 7 disposed between the left side plate 5A and the right side plate 5B. In addition, an operating member 12 for adjusting the output of the drive motor 8 is disposed on the rear portion of the control box 10. The operating member 12 of this embodiment is in the form of a dial disposed on a support shaft that is rotatably supported at the rear of the control box 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] In addition, if Figure 2 , Figure 3 As shown, a clutch mechanism 17 that can switch the spool 7 to a fishing line winding state or a free rotation state is arranged on the frame 3 (the right frame 3b in this embodiment). The 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 between a clutch ON state and a clutch OFF state on the rear side of the spool 7 by a clutch operating member 18, and the clutch operating member 18 is arranged to be displaceable in the up and down directions. Figure 1The clutch-ON state (power transmission state) is shown, and the clutch operating member 18 can be switched to the clutch-OFF state by pressing the clutch operating member 18 .

[0015] Furthermore, the clutch OFF state can be automatically reset to the clutch ON state by the retracting operation of the manual handle 6 , the driving of the driving motor 8 , and the like.

[0016] Between the right frame 3b and the right cover 4b, a mounting plate 20 described later is provided. An engaging hole 22 is formed on the rear end side of the mounting plate 20, and positioning can be performed by fitting the engaging hole 22 with a convex portion 3d formed on the right frame 3b. In this state, by screwing a plurality of screws 23a to 23d from the outside into screw holes (or screw holes formed on the protrusion) 3f to 3i formed on the right frame 3b, the mounting plate 20 can be fixed to the right frame 3b without rotation.

[0017] Next, refer to Figures 6 to 8 The configuration of the drive motor 8 and the mounting plate 20 will be described. The drive motor 8 includes motor components such as a magnet that forms a magnetic field along the circumferential direction, an armature on which a coil is wound in a manner opposite to the magnet, and a commutator mounted on the end of the output shaft 8a, and these motor components are accommodated in a motor case 8A formed in a substantially cylindrical shape. In addition, the output from the output shaft 8a of the drive motor 8 is decelerated by the speed reduction mechanism 30 provided on the right frame 3b side, and is transmitted to the reel 7 through the power transmission mechanism 40.

[0018] The mounting plate 20 accommodates the power transmission parts including the speed reduction mechanism 30 on the right frame 3b side and supports the two gears 41, 42 and the bearing parts 50 etc. constituting the power transmission mechanism 40. That is, the mounting plate 20 of the present embodiment includes: a housing portion 20A for accommodating the speed reduction mechanism 30 provided on the output shaft 8a of the drive motor 8; and a gear support portion 20B for supporting the two gears 41, 42 constituting the power transmission mechanism.

[0019] The motor case 8A is open on both sides in the axial direction. The right frame 3 b side is closed by the mounting plate 20 , and the left frame 3 a side is closed by a cover member 26 fixed to the left frame 3 a .

[0020] The motor case 8A is formed of a raw material such as a metal such as aluminum, titanium, or magnesium, a resin, or FRP, and is formed into a cylindrical body that is a separate component from the frame 3. The motor case 8A is formed of a material different from that of the frame 3, and contains the above-mentioned output shaft 8a, magnets, armatures, commutators, and other motor components.

[0021] The housing portion 20A is formed into a substantially cylindrical shape that is raised in the axial direction relative to the gear support portion 20B, and the speed reduction mechanism 30 is housed in the internal space thereof. The speed reduction mechanism 30 of the present embodiment includes a planetary gear mechanism (two-stage) mounted on the output shaft 8a of the drive motor 8, and includes two sun gears 31a and 31b mounted on the output shaft 8a, two planetary gears 32a and 32b meshing with the two sun gears 31a and 31b, and an internal gear 33 having internal teeth 33a meshing with each of the planetary gears 32a and 32b. In addition, external teeth 33b are formed on the outer peripheral surface of the internal gear 33, and the rotational drive decelerated by the speed reduction mechanism 30 is output to the two gears 41 and 42 constituting the power transmission mechanism 40 through the external teeth 33b.

[0022] Usually, since the side cover (cover) is an exposed exterior part and is mostly composed of a curved surface, it is impossible to fix and arrange the speed reduction mechanism 30 or the power transmission mechanism 40 in an appropriate position only on the side cover. On the contrary, by providing the above-mentioned mounting plate 20, the speed reduction mechanism 30 and the power transmission mechanism 40 can be arranged in an appropriate position, and the assembly and maintenance can be improved. In addition, by providing a raised receiving portion 20A for accommodating the speed reduction mechanism 30 on the mounting plate 20, the width direction of the reel body can be made compact.

[0023] The motor case 8A and the mounting plate 20 have a fitting structure for fitting the motor case 8A and the mounting plate 20. That is, in the prior art, the motor case is supported on a frame and the mounting plate is fixed to the frame, but in the embodiment of the present invention, the motor case 8A is fitted to the mounting plate 20.

[0024] In this way, by making the motor housing 8A fit with the mounting plate 20, the accumulated tolerance from the motor housing to the frame and from the frame to the mounting plate as in the past can be reduced, the coaxiality between the output shaft 8a of the drive motor 8 and the reduction mechanism 30, bearing parts, etc. can be improved, and the reduction in motor output can be suppressed.

[0025] The fitting structure in this embodiment is that the convex portion 8b is formed on the motor housing 8A side, and the concave portion 20b that can fit the convex portion 8b is formed on the mounting plate 20 side. At this time, since the motor housing 8A is formed into a cylindrical shape with a substantially circular cross section centered on the output shaft 8a, the convex portion 8b is formed into a ring shape in which the outer edge with the largest diameter extends in the axial direction. In addition, the concave portion 20b on the mounting plate 20 side is composed of an annular groove formed in the same circle as the accommodating portion 20A and extending in the axial direction on the inner surface of the inner top edge so as to be able to fit with the convex portion 8b formed in a ring shape.

[0026] Specifically, the fitting structure of the present embodiment is constituted by the outer peripheral surface of the annular convex portion 8b and the inner peripheral surface of the annular concave portion 20b, and both the convex portion 8b and the concave portion 20b are constituted by a circle centered on the output shaft 8a of the drive motor 8.

[0027] According to such a circular fitting structure, since the orbit of the reduction mechanism 30 such as the planetary gear connected to the output shaft 8a is circular, it is possible to form a fitting structure that ensures the minimum space required for rotation. In addition, by forming the fitting portion as an annular convex portion formed on the radially outer end of the end of the motor housing 8A, it is easy to install it relative to the recessed portion 20b, and since it is fitted at the position of the maximum diameter, a stable fixed state can be obtained without loosening.

[0028] In addition, if Figure 6 , Figure 7 As shown, in this embodiment, since the internal gear 33 outputting power to the outside is arranged in the housing portion 20A, an arc-shaped cutout portion 20d is formed on the outer peripheral surface of the housing portion 20A so that the external teeth 33b and the gear 41 are engaged.

[0029] Furthermore, the convex portion 8 b formed on the motor case 8A in the present embodiment has a function of positioning the mounting plate 20 mounted on the frame 3 . In this way, since the motor case 8A has a positioning function for the mounting plate 20 relative to the frame 3, there is no need to provide a separate protrusion or the like to position the mounting plate 20 on the frame 3, so that the internal structure can be simplified and reduced in size and weight.

[0030] As described above, in this embodiment, the convex portion 8b of the motor housing 8A has a positioning function for the mounting plate 20 relative to the frame 3. In addition, in order to stably fix the motor housing 8A to the frame 3, for example, arc-shaped convex portions 8e may be formed in advance on the outer peripheral surface of the motor housing 8A in the circumferential direction and separated in the axial direction at two locations, and a groove 3e that fits with the convex portion 8e may be formed on the frame 3. According to this configuration, the motor housing 8A can be stably held 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-described embodiment, and various modifications are possible. The fitting structure between the motor housing 8A and the mounting plate 20 may be formed by a simple concave-convex fitting other than the annular convex portion 8b and the annular concave portion 20b having the cutout portion 20d. In addition, a structure may be formed in which a concave portion is formed on the motor housing side and a convex portion is formed on the mounting plate side, or an inner peripheral surface of the convex portion 8b of the motor housing 8A is fitted with an outer peripheral surface of the accommodating portion 20A of the mounting plate 20.

[0032] In addition, the power transmission mechanism 40 supported on the mounting plate 20 only needs to have the function of transmitting the rotational driving force of the drive motor 8 to the reel 7 side, and various changes can be made, for example, by transmitting power through a transmission belt, etc. In addition, the mounting plate 20 and the manual handle 6 mentioned above can also be arranged on the left side of the plate 5A. In addition, various changes can also be made to the clutch mechanism.
