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 motor supported on a frame of the reel body drives the reel to rotate and reel in the fishing line. 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. In addition, the driving motor is accommodated in a motor housing integrally formed on the frame, and a mounting plate is mounted on the frame to support the planetary gear mechanism and bearing parts constituting the speed reduction mechanism.

[0003] Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2010-51272 Summary of the invention

[0004] As described above, by integrally forming the motor housing on the frame, the inner diameter of the portion that accommodates the motor components can be maximized, and the motor output can be improved. In addition, since the frame and the motor housing are integrated, the accuracy of the output shaft of the motor can be easily obtained.

[0005] On the other hand, in the case of manufacturing an electric fishing reel at a low cost, when the motor housing and the frame are integrated, it is necessary to simultaneously form the motor housing and the frame structure by resin molding or die casting. However, in such a method, burrs are generated due to mold reasons such as strength and durability, which leads to an increase in the overall weight of the reel. In addition, there is the following problem, that is, since the motor housing and the frame are integrated, when the molding and processing steps of the frame are not completed, the motor components cannot be installed, resulting in a delay in the overall production process. Furthermore, since the motor case and the frame are integrally formed, it is difficult to make the motor case an exposed exterior component (designed component).

[0006] The present invention is made in view of the above problems, and the technical problem to be solved is to provide an electric fishing reel that is lightweight, has high production efficiency, and has excellent design (creativity).

[0007] In order to achieve the above-mentioned purpose, the electric fishing reel involved in the present invention is a driving motor for rotating a reel for winding a fishing line, characterized in that it has a reel body and a frame constituting the reel body and a motor housing that accommodates the motor components of the driving motor inside, the motor housing and the frame are formed by separate bodies and constitute exposed appearance parts, and the motor housing is embedded and supported on the frame through the two side ends in the axial direction.

[0008] According to the electric fishing reel of the present invention, since the motor housing and the frame that house the components of the drive motor are formed separately, the efficiency of the production process can be achieved by performing the production processes of the two separately. In addition, since only a frame with less burrs can be formed by die casting or the like (only a frame without a motor housing), the overall weight of the reel can be reduced. In addition, since the motor housing can be an exposed appearance part, the design (creativity) can be improved.

[0009] According to the present invention as described above, it is possible to obtain an electric fishing reel that is lightweight, has high productivity, and is excellent in design. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] Below, refer to Figures 1 to 9 An embodiment of the electric fishing reel according to the present invention is described. Figure 1 The 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.

[0012] like Figures 1 to 6 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 4 to 6 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).

[0013] A manual handle 6 for winding and reeling is provided on one side plate (right side plate 5B) constituting the reel body 5, and a reel 7 for winding the fishing line is rotatably supported between the left side plate 5A and the right side plate 5B. In the present embodiment, a driving motor 8 is held between the left frame 3a and the right frame 3b in front of the reel 7 (see FIG. Figures 2 to 6 ) 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.

[0014] 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.

[0015] In addition, the frame 3 (the right frame 3b in this embodiment) is provided with a clutch mechanism 17 (see FIG. 1 ) which can switch the reel 7 to a fishing line winding state or a free rotation state. Figure 4 and Figure 5 The clutch mechanism 17 has the function of connecting and disconnecting the power transmission from the manual handle 6 and the drive motor 8 to the reel 7, and is configured to switch between the clutch ON state and the clutch OFF state on the rear side of the reel 7 through a clutch operating member 18, and the clutch operating member 18 is configured to be displaceable in the up-down direction. Figure 1 The 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 .

[0016] Furthermore, the clutch OFF state can be automatically reset to the clutch ON state by retracting the manual handle 6 , driving the drive motor 8 , and the like.

[0017] 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.

[0018] Next, refer to Figures 7 to 9 The configuration of the drive motor 8 and the mounting plate 20 will be described. The drive motor 8 includes motor components such as magnets that form a magnetic field along the circumferential direction, an armature with coils wound in a manner opposite to the magnets, and a commutator mounted on the end of the output shaft 8a. These motor components are housed inside a motor case 8A formed in a roughly cylindrical shape.

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

[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] As described above, the motor housing 8A of the drive motor 8 and the frame 3 are formed as separate bodies. Since the frame 3 and the motor housing 8A are not formed integrally as in the past, the production processes can be managed in parallel. In addition, since the motor housing 8A does not have burrs due to being formed integrally with the frame, and the raw materials can be freely selected, it is possible to achieve effects such as light weight (thin wall) and reduced friction. And, as Figure 2 As shown, since it can be an exposed design part that can be visually recognized from the outside, it is possible to add color, pattern, etc., so that the design can be improved.

[0022] The mounting plate 20 accommodates 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 has both the function of a housing portion 20A for accommodating the speed reduction mechanism 30 provided on the output shaft 8a of the drive motor 8 and the function of a gear support portion 20B for supporting the two gears 41, 42 constituting the power transmission mechanism.

[0023] 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 sun gears 31a and 31b, and an internal gear 33 having internal teeth 33a meshing with 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.

[0024] Usually, since the side cover (cover) is an exposed exterior part and most of them have 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.

[0025] 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.

[0026] 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.

[0027] The fitting structure in this embodiment is that the convex part 8b is formed on the motor housing 8A side, and the concave part 20b that can fit the convex part 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 part 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 part 20b on the mounting plate 20 side is formed by an annular groove formed in the same circle as the accommodating part 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 part 8b formed in the ring shape.

[0028] 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.

[0029] 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.

[0030] like Fig. 9As shown, in this embodiment, a surplus space G serving as a relief portion is formed between the axial end surface of the convex portion 8b and the receiving surface of the concave portion 20b of the housing portion 20A. Figure 5 As shown, the mounting plate 20 is positioned and fixed relative to the right frame 3b through the reference surface by screwing a plurality of screws 23a to 23d from the outside. If the convex portion 8b and the concave portion 20b are received in the circumferential and axial directions, it may not be well fixed due to the relationship with some parts such as the speed reduction mechanism, but by providing the above-mentioned remaining space G, the convex portion 8b and the concave portion 20b do not contact in the axial direction but are received in the circumferential direction, so that the mounting plate 20 can be stably fixed.

[0031] In addition, if Figure 7 , Figure 8 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.

[0032] In addition, the convex portion 8b formed on the motor housing 8A in this embodiment has the function of positioning the mounting plate 20 mounted on the frame 3. Fig. 9 As shown, in this embodiment, the protrusion 8 b of the motor case 8A protrudes axially outward from the frame 3 , so that the mounting plate 20 can be positioned relative to the frame 3 reliably and easily.

[0033] 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.

[0034] The opening of the motor case 8A on the left frame 3 a side is closed by a cover member 26 fixed to the left frame 3 a. like Figure 3 As shown in (b), the end of the left frame 3a side of the motor housing 8A protrudes axially from the surface of the left frame 3a, and the opening on the left side of the housing 8A is closed and fixed by abutting the cover part 26 on the axial end face of the protruding part.

[0035] That is, a plurality of protrusions 8d are formed in the circumferential direction of the motor housing 8A, and radially protruding protrusions 26a are formed at corresponding positions on the cover member 26. By aligning the screw holes provided on both and screwing the screws 27 in from the outside, the cover member 26 can be fixed to the motor housing 8A (closing the opening on the left frame 3a side of the motor housing 8A).

[0036] The cover member 26 preferably closes the opening of the motor case 8A and is positioned and fixed relative to the right frame 3 a in the axial direction and the rotational direction. For example, Figure 3 As shown in (a), by forming a protrusion 8d' on the cover member 26 in advance, the protrusion 8d' is formed with a through hole penetrating in the axial direction, and the through hole is embedded in the protrusion 3k formed on the frame 3a, so that the cover member 26 can be stopped from rotating relative to the right frame 3a. Figure 3 As shown in (b), a protrusion 3a' is provided in advance on the frame 3a adjacent to the formed plurality of protrusions 8d, and by screwing a screw 28 therein from the outside, the cover member 26 can be fixed to the right frame 3a in the axial direction.

[0037] Thus, the projection 26a is formed in advance on the outer periphery of the cover member 26. The projection 26a can prevent the cover member 26 that closes the opening of the motor case 8A from being displaced in the axial direction while being rotationally fixed relative to the left frame 3a. Furthermore, in order to prevent the manual handle from being driven when the driving motor 8 is driven, a one-way clutch 29 is disposed inside the cover member 26 , and the one-way clutch 29 supports the output shaft 8 a so as to be rotatable in one direction. According to the fitting support structure of the present embodiment, the motor case 8A is not in a one-sided support state, and thus can be supported stably.

[0038] like Fig. 9 As shown, the mating portion of this embodiment is composed of an arc-shaped protrusion 8e and an arc-shaped groove 3e, wherein the arc-shaped protrusion 8e is formed along the circumferential direction at both end sides of the outer peripheral surface of the motor housing 8A, and the arc-shaped groove 3e is formed at a corresponding position of the frame 3 and is mated with the protrusion 8e of the motor housing 8A.

[0039] Thus, by forming two convex portions spaced apart from each other in the axial direction on the motor housing 8A in advance and forming a corresponding groove 3e that fits with the convex portion 8e on the frame 3, the motor housing 8A can be stably held, and the accuracy of the output shaft 8a can be improved. In addition, by making the part for fitting support the outer peripheral surface of the motor housing 8A, the motor housing portion does not become longer in the axial direction, the width can be suppressed, and the reel body 5 can be miniaturized.

[0040] In the above-mentioned structure, it is preferable to preliminarily provide a waterproof pad 60 (at the joint between the motor housing 8A and the frame 3) Fig. 9 In the embodiment, the waterproof pad 60 is only provided on the fitting part on the right frame 3b side, but it can also be provided on the fitting part on the left frame 3a side. In this way, by providing the waterproof pad 60 on the fitting part of the two, it is possible to prevent seawater and the like from entering the interior. In addition, the fitting part can also be configured such that a groove is formed in advance on the outer peripheral surface of the motor housing 8A, and a convex part that fits with the groove is provided at a corresponding position on the frame 3 side.

[0041] 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. For example, the number of locations where the motor case 8A and the frame 3 are fitted and supported may be two or more, and the locations and fitting structures thereof may be modified as appropriate.

[0042] In addition, the interlocking structure of the motor housing 8A and the mounting plate 20 can also be constructed by forming a recessed portion on the motor housing 8A and a convex portion on the mounting plate 20, and can also be constructed by interlocking the inner peripheral surface of the convex portion 8b of the motor housing 8A with the outer peripheral surface of the accommodating portion 20A of the mounting plate 20.

[0043] 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 winding drum 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 can also be arranged on the left side of the plate 5A. In addition, various changes can be made to the clutch mechanism.
