Description

Electric fishing reel for fishing

Technical Field

The invention relates to an electric fishing reel for fishing.

Background

Conventionally, as one type of fishing reel, there is known an electric fishing reel (hereinafter, may be simply referred to as an electric reel) in which a fishing line is wound by rotating a spool by a rotational driving force of a motor. Generally, such an electric reel is roughly classified into a type in which a motor is disposed in an internal space of a spool and a type in which a motor is disposed on a front side of the spool (a side in a fishing line reel-out direction).

In any type, the motor is accommodated in a motor accommodating portion formed in the reel unit, and is held in the motor accommodating portion by a cover-shaped motor holder that closes an opening of the motor accommodating portion. In this case, the motor holder is likely to receive a thrust load from the motor or a radial load due to a rotational torque, and therefore needs to be firmly fixed to the reel unit. Conventionally, a motor bracket is generally screwed to a reel unit by a fastening member such as a screw or a bolt (see, for example, patent document 1).

[ problem to be solved by the invention ]

However, when the motor holder is screwed to the reel unit, for example, a flange piece having a screw insertion hole is provided in the motor holder, and a screw receiving portion having a screw hole for combining the flange piece is provided in the reel unit. In particular, since the flange piece and the screw receiving portion need to be provided radially outward of the opening of the motor housing portion, the size of the motor holder itself is likely to be increased, and the size of the reel unit is also likely to be increased accordingly. In particular, when the motor is disposed on the front side of the spool, the size of the motor holder and the like tends to be increased.

In such a case, it is difficult to further reduce the size of the electric reel, and there is room for improvement. Further, since fastening members such as screws and bolts are required to fix the motor holder to the reel unit, the number of parts increases, and it is difficult to achieve cost reduction and improvement in maintainability.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electric fishing reel that can be downsized and can reduce the number of components.

[ solution for solving problems ]

(1) The invention relates to an electric fishing reel for fishing, which is characterized by comprising a fishing reel body, a motor and a motor bracket, wherein the fishing reel body is provided with a rotatable winding reel; the motor is arranged in a motor accommodating barrel and is used for driving the winding reel to rotate, wherein the motor accommodating barrel is arranged on the fishing reel body; the motor holder is assembled to the reel unit so as to close the motor accommodating cylinder, and is used for fixing the motor to the reel unit, and the reel unit includes a main body frame and a side cover, wherein the main body frame is provided with the motor accommodating cylinder and a side wall frame, and the side wall frame is provided with an opening part of the motor accommodating cylinder; the side cover is combined with the main body frame in a mode of covering the side wall frame, and the motor support is provided with a cover body and a clamping part, wherein the cover body seals an opening part of the motor accommodating cylinder; the engaging portion is formed to protrude from the cover toward the radially outer side of the motor accommodating cylinder, and is engageable with an engaged portion formed on the side wall frame or the side cover in the circumferential direction of the motor accommodating cylinder, and the motor holder is restricted from moving in the motor axial direction of the motor by being sandwiched between the side wall frame and the side cover.

According to the electric fishing reel for fishing of the present invention, the motor holder is assembled to the side wall frame so as to close the opening of the motor housing tube by the cover body, and the side cover is assembled to the main body frame so as to cover the side wall frame. Accordingly, the motor holder can be sandwiched between the side wall frame and the side cover, and the movement of the motor holder in the motor axial direction can be restricted. That is, by sandwiching the motor holder between the side wall frame and the side cover, the opening of the motor accommodating tube can be closed by the motor holder while restricting the movement of the motor holder in the motor axial direction.

Accordingly, when the motor disposed in the motor housing cylinder is driven, the thrust load caused by the driving is transmitted from the motor to the motor holder, and the movement of the motor holder in the motor axial direction is restricted, so that the thrust load can be received.

The motor holder is not merely sandwiched between the side wall frame and the side cover, but is engaged with an engaged portion formed on the side wall frame or the side cover in the circumferential direction of the motor accommodating cylinder by an engaging portion on the outer side in the radial direction of the motor accommodating cylinder. Therefore, the movement of the motor holder in the circumferential direction, that is, the movement of rotating around the motor axis can be suppressed. Accordingly, even if a radial load about the motor axis caused by the rotational torque is transmitted from the motor to the motor bracket at the time of motor driving, the radial load can be received.

In this case, the motor holder can close the opening of the motor housing tube while appropriately receiving the thrust load and the radial load from the motor, and therefore the motor disposed in the motor housing tube can be stably fixed.

In particular, when the motor holder is assembled to the reel unit, since fastening members such as screws and bolts are not required, a plurality of parts required for the fastening can be omitted. Therefore, the number of parts can be reduced, which contributes to cost reduction of the entire electric fishing reel for fishing and improvement of maintainability. Further, since it is not necessary to provide a space for installing a fastening member or a member such as a flange piece for fastening, the motor holder can be easily designed compactly, which contributes to downsizing of the entire electric fishing reel for fishing.

(2) The engaged portion may be formed in plurality at intervals in the circumferential direction, and the engaging portion may be engaged with at least one of the engaged portions in the circumferential direction.

In this case, since the plurality of engaged portions are formed, when the motor bracket is assembled to the side wall frame, for example, it is possible to perform assembly such that the engaging portions are engaged with the engaged portions selected according to the assembly condition or the like. Therefore, the assembly can be easily performed, thereby achieving an improvement in assembly efficiency.

(3) The engaging portion may be formed in plurality at intervals in the circumferential direction so as to correspond to the plurality of engaged portions, and may be engaged with each of the plurality of engaged portions in the circumferential direction.

In this case, since the motor holder can be assembled while engaging the engaged portion with the engaging portion at a plurality of locations, the radial load transmitted from the motor to the motor holder can be received at a plurality of locations. Therefore, the posture of the motor bracket can be more stabilized, and the motor can be more stably fixed. Further, since the radial load is received at a plurality of locations, the load applied to the engagement portion of each of the engaged portion and the engaging portion can be reduced. Therefore, the motor bracket can be stably assembled for a long time, and thus, the reliability of the product can be improved.

(4) The engaged portion may be formed in the side wall frame, and the side cover may be provided with a regulating member that regulates movement of at least one of the engaging portions in the motor axial direction between the side cover and the side wall frame.

In this case, when the motor bracket is assembled to the side wall frame, the engaging portion can be circumferentially engaged with the engaged portion formed in the side wall frame. Accordingly, the motor holder can be combined in a state in which the movement of rotating around the motor axis is suppressed. In particular, since the engaged portion is formed in the side wall frame constituting the main body frame, the radial load transmitted from the motor to the motor holder can be shared by the main body frame having high rigidity, and the posture of the motor holder can be easily stabilized.

Further, by combining the side cover with the main body frame so as to cover the side wall frame, the movement of the engaging portion itself in the motor axial direction can be restricted by the restricting member while sandwiching the motor holder between the side wall frame and the side cover. Therefore, the thrust load and the radial load transmitted to the motor holder can be effectively received by the engaging portion at the same time.

[ Effect of the invention ]

According to the present invention, it is possible to provide an electric fishing reel that can be made compact and can reduce the number of components.

Detailed Description

Hereinafter, embodiments of an electric fishing reel according to the present invention will be described with reference to the drawings.

In the present embodiment, a description will be given of an example in which a dual-bearing reel is used as the electric fishing reel for fishing.

As shown in fig. 1 to 4, an electric reel (an electric fishing reel according to the present invention) 1 of the present embodiment mainly includes a reel unit 2, a handle 3, a spool 4, and a clutch mechanism 6, wherein the reel unit 2 is attachable to a fishing rod (not shown); the handle 3 is attached to the reel unit 2 so as to be rotatable about a handle axis O1; the spool 4 is rotatable about a spool axis O2 parallel to the handle axis O1 with respect to the reel unit 2, and is used for winding a fishing line not shown; the clutch mechanism 6 has a clutch lever 5.

As shown in fig. 5 to 7, the electric reel 1 of the present embodiment includes a motor 8 and a motor holder 9, wherein the motor 8 is disposed in a motor housing tube 7 provided in the reel unit 2, and drives the spool 4 to rotate; the motor holder 9 is assembled to the reel unit 2 so as to close the motor accommodating tube 7, and fixes the motor 8 to the reel unit 2.

In the present embodiment, the handle axis O1 and the spool axis O2 are arranged parallel to each other, and a direction along these axes is defined as a left-right direction L1. A direction perpendicular to the left-right direction L1 and along the fishing line unwinding direction wound around the spool 4 is defined as a front-rear direction L2.

Further, the direction in which fishing line is paid out from the spool 4 is defined as the front side and the opposite direction is defined as the rear side in the front-rear direction L2, and the left and right sides are defined as the viewpoint of the electric reel 1 viewed from the rear side (the side of the angler). Therefore, for example, fig. 1 is a perspective view of the electric reel 1 viewed from obliquely above and from the left rear.

(fishing line reel unit)

As shown in fig. 1 to 4, the reel unit 2 includes a main body frame 10, side covers 20, and a front cover 30, wherein the side covers 20 cover both right and left sides of the main body frame 10; the front cover 30 covers the front side of the main body frame 10.

The main body frame 10 is, for example, a molded component made of synthetic resin or metal (e.g., aluminum die-cast). The main body frame 10 has a 1 st side wall 11, a 2 nd side wall 12, and a connecting member 13, wherein the 1 st side wall 11 and the 2 nd side wall 12 are arranged to face each other in the left-right direction L1 with the spool 4 interposed therebetween; the connecting member 13 connects the 1 st and 2 nd side walls 11 and 12 to each other in the left-right direction L1.

The 1 st side wall (side wall frame according to the present invention) 11 is a left side wall disposed on the left side (LH) of the spool 4. On the other hand, the 2 nd side wall 12 is a right side wall disposed on the right side (RH) of the bobbin 4. The handle 3 is disposed further to the Right (RH) than the 2 nd side wall 12, and is attached to the main body frame 10 by the 2 nd side wall 12.

Therefore, the electric reel 1 of the present embodiment is a right-hand grip type reel. The 2 nd side wall 12 is formed to protrude downward from the 1 st side wall 11 for reasons such as provision of a connector portion 23 described later.

The connecting member 13 is formed in a plate shape connecting the 1 st side wall 11 and the 2 nd side wall 12 in the left-right direction L1, and is disposed in the vicinity of a lower portion of the 1 st side wall 11. Accordingly, the 1 st sidewall 11 and the 2 nd sidewall 12 are firmly connected by the connection member 13.

Further, a mounting leg piece 14 for mounting the electric reel 1 to the fishing rod is formed at a central portion of the link member 13 in the left-right direction L1, and the mounting leg piece 14 extends in the front-rear direction L2.

In the main body frame 10 configured as described above, at least the motor housing tube 7 housing the motor 8 therein, the spool 4, the clutch lever 5, and the like are disposed between the 1 st side wall 11 and the 2 nd side wall 12.

The spool 4 is disposed between the 1 st side wall 11 and the 2 nd side wall 12 so as to be located on the rear side of the handle axis O1. The motor accommodating cylinder 7 is disposed between the 1 st side wall 11 and the 2 nd side wall 12 so as to be located on the front side of the handle axis O1. Therefore, the electric reel 1 of the present embodiment is a so-called bobbin-outside motor (motor is provided outside the bobbin) type in which the motor 8 is disposed at a position forward of the bobbin 4.

The motor housing tube 7 is disposed between the 1 st side wall 11 and the 2 nd side wall 12 so as to form the opening 62 in the 1 st side wall 11.

The side cover 20 has a 1 st side cover (a side cover according to the present invention) 21 and a 2 nd side cover 22, wherein the 1 st side cover 21 is combined with the main body frame 10 in a manner of covering the 1 st side wall 11 formed with the opening part of the motor accommodating cylinder 7 from the left side (LH); the 2 nd side cover 22 is assembled to the main body frame 10 so as to cover the 2 nd side wall 12 from the right side (RH).

The 1 st side cover 21 is formed to bulge toward the left side (LH) and is screwed to the 1 st side wall 11, for example. Thus, a predetermined housing space is formed between the 1 st side cover 21 and the 1 st side wall 11. The 1 st side cover 21 will be described in detail later.

The 2 nd side cover 22 is formed so as to bulge toward the right side (RH), and is screwed to the 2 nd side wall 12, for example. Accordingly, a predetermined housing space is formed between the 2 nd side cover 22 and the 2 nd side wall 12.

A connector 23 is attached to a portion of the 2 nd-side cover 22 located at the front lower portion, with a connection end not shown facing downward, and the connector 23 is used to connect a power supply reel wire or a portable battery for supplying electric power from an external power supply. Further, in the drawings, the state where the connection terminals are protected by the protective cover 24 is illustrated.

The front cover 30 is assembled to the main body frame 10 so as to cover the front portion of the main body frame 10 from the front. Specifically, the front cover 30 is combined with the front portions of the 1 st side wall 11 and the 2 nd side wall 12 so as to cover the motor housing tube 7 from the front, and is screwed to the 1 st side wall 11 and the 2 nd side wall 12, for example. The front cover 30 is attached so as not to close a movement region of the level wind device 55 described later.

(counter box)

The counter case 40 is provided on the upper portion of the main body frame 10 configured as described above. The counter case 40 is fixed to the upper portion of the 1 st side wall 11 and the upper portion of the 2 nd side wall 12 by, for example, screwing in, in a state of being disposed between the 1 st side wall 11 and the 2 nd side wall 12.

The counter case 40 mainly includes a thin case main body 41, a display unit 42, and a motor control unit not shown, wherein the case main body 41 is longer in the front-rear direction L2 than in the left-right direction L1; the display portion 42 is provided in the cartridge main body 41; the motor control section is provided in the cartridge main body 41.

The display unit 42 is configured by, for example, a liquid crystal display or the like, and is exposed to the upper surface of the case main body 41 in a state protected by a glass cover or the like. The motor control unit is constituted by a microcomputer mounted with a CPU or the like, for example, and performs control of the motor 8 and display control for displaying various information on the display unit 42.

The motor control unit receives, for example, control signals from a plurality of (3 in the illustrated example) operation buttons 43 provided on the upper surface of the cartridge main body 41, control signals from an operation switch 44 provided on the upper surface of the cartridge main body 41, and control signals from a not-illustrated bobbin sensor (for example, a sensor for detecting the rotation speed, rotation direction, and the like of the bobbin 4).

Accordingly, the motor control unit can arbitrarily adjust the take-up speed or the take-up acceleration by displaying various information such as the input time of the hook unit, the water depth of the hook unit, the take-up speed or the take-up torque of the motor 8 on the display unit 42, or controlling the rotation of the motor 8 in response to the operation of the operation switch 44, based on various control signals.

Therefore, the fisher can perform the manual winding operation by the handle operation and the automatic winding operation by the operation switch 44.

(handle)

The handle 3 is disposed on the right side (RH) of the main body frame 10 and the 1 st side cover 21. The handle 3 has a handle shaft portion 50, a handle arm 51, and a handle grip 52, wherein the handle shaft portion 50 is disposed rotatably about a handle axis O1; the handle arm 51 is non-rotatably attached to the handle shaft portion 50; the handle grip 52 is attached to the end of the handle arm 51 so as to be rotatable about an axis parallel to the handle axis O1.

Between the handle arm 51 and the 1 st side cover 21, a drag device 53 (star drag device) is provided, which is disposed coaxially with the handle axis O1. The drag device 53 applies an arbitrary drag force to the spool 4 when winding the fishing line to brake the rotation of the spool 4, thereby playing a role of contributing to the suppression of the fishing line cutting.

In a state where the clutch mechanism 6 is in a clutch engaged state, the rotational torque from the handle 3 configured as described above is directly transmitted to the spool 4 via a rotation transmission mechanism not shown. In the present embodiment, a so-called single-grip type in which the grip knob 52 is attached to one end portion of the grip arm 51 is described as an example, but the present invention is not limited to this. For example, the so-called two-handle type electric reel 1 may be configured such that the handle grips 52 are attached to both end portions of the handle arm 51 and the center portion of the handle arm 51 is non-rotatably attached to the handle shaft portion 50.

(winding reel)

The spool 4 is disposed between the 1 st side wall 11 and the 2 nd side wall 12 of the main body frame, and is supported by the 1 st side wall 11 and the 2 nd side wall 12 via bearings, not shown, so as to be rotatable about the spool axis O2.

The spool 4 has a spool rotation shaft portion, not shown, which rotates about a spool axis O2, and a spool body portion 4 a; the spool body 4a is disposed coaxially with the spool rotation shaft and rotates in conjunction with the spool rotation shaft.

(Clutch mechanism)

The clutch mechanism 6 is switchable between a clutch engaged state in which a rotational torque from the handle 3 can be transmitted to the spool 4 by a rotation transmission mechanism, not shown, and a clutch disengaged state by operation of the clutch lever 5; in the clutch off state, the rotational torque cannot be transmitted. Therefore, in the clutch engaged state, by rotating the operation handle 3, the rotational torque generated by the rotational operation of the handle 3 can be transmitted to the spool 4, and the spool 4 can be rotated about the spool axis O2. Accordingly, the manual winding operation can be performed.

When the clutch mechanism 6 is in the clutch off state, the rotational torque generated by the rotational operation of the handle 3 is not transmitted to the spool 4, and the spool 4 is in a freely rotatable state (spool free state).

The clutch lever 5 is a switching lever for switching the clutch mechanism 6 between a clutch engaged state and a clutch disengaged state. The clutch lever 5 is disposed behind the spool 4 between the 1 st side wall 11 and the 2 nd side wall 12, and is vertically movable so as to be swingable about the spool axis O2.

The rotation transmission mechanism is configured to transmit the rotation torque to the spool 4 while increasing the speed of rotation of the handle 3. The rotation transmission mechanism is configured to transmit the rotation torque generated by the rotational operation of the handle 3 not only to the spool 4 but also to a level wind device mechanism (not shown) having a level wind device 55 when the clutch mechanism 6 is in the clutch engaged state.

The level wind device 55 is disposed between the motor housing tube 7 and the counter case 40, and is capable of reciprocating in the left-right direction L1 between the 1 st side wall 11 and the 2 nd side wall 12 in accordance with the rotation of the spool 4 (see fig. 3). Accordingly, the fishing line can be wound around the spool 4 uniformly without any bias.

When the motor 8 is driven in the case where the clutch mechanism 6 is in the clutch engaged state, the rotation transmission mechanism can transmit the rotation torque generated by the driving of the motor 8 to the spool 4. Thus, the automatic winding operation can be performed. The rotation transmission mechanism transmits the rotation torque to the spool 4 while decelerating the rotation of the motor 8.

(Motor containing cylinder)

As shown in fig. 3, the motor housing tube 7 is disposed between the 1 st side wall 11 and the 2 nd side wall 12 on the front side of the handle axis O1, and is formed in a top cylindrical shape disposed coaxially with the motor axis O3 extending in the left-right direction L1.

Specifically, as shown in fig. 5 to 8, the motor housing cylinder 7 is formed in a bottomed cylindrical shape having a housing cylinder main body 60 and a bottom wall 61, wherein the housing cylinder main body 60 is formed in a cylindrical shape centered on a motor axis O3; the bottom wall 61 closes a right opening 62 of the cartridge main body 60. Accordingly, the motor housing tube 7 has an opening 62 in the 1 st side wall 11 and is open to the Left (LH).

In the illustrated example, the housing cylinder main body 60 is formed integrally with the bottom wall 61, but the present invention is not limited to this case. For example, the housing cylinder body 60 and the bottom wall 61 may be formed separately, and the housing cylinder body 60 and the bottom wall 61 may be integrally combined by screwing, fitting, or the like.

In the present embodiment, a direction intersecting the motor axis O3 is referred to as a radial direction and a direction around the motor axis O3 is referred to as a circumferential direction, as viewed from the motor axis O3 direction.

As shown in fig. 3, the housing tube main body 60 is disposed between the front portion of the 1 st side wall 11 and the front portion of the 2 nd side wall 12 so as to be disposed below the level wind turbine 55. Therefore, the motor accommodating cylinder 7 is disposed so as to be exposed to the front. However, a part of the motor accommodating cylinder 7 is protected from the front side by the front cover 30.

As shown in fig. 5 to 8, a diameter-enlarged tube 63 having a larger diameter than the other portion is formed in the portion of the housing tube body 60 on the opening 62 side. Therefore, the motor accommodating cylinder 7 is integrally formed with the 1 st side wall 11 through the diameter-enlarging cylinder 63. Further, a cylindrical boss portion 64 protruding to the Right (RH) side is formed in the central portion of the bottom wall 61.

Here, the 1 st side wall 11 constituting the main body frame 10 will be described in detail.

As shown in fig. 5, the 1 st side wall 11 functions as a left side wall of the main body frame 10 and is normally covered with the 1 st side cover 21. The length of the 1 st side wall 11 in the front-rear direction L2 is formed longer than the length in the vertical direction, and as described above, the motor storage cylinder 7 is integrally formed on the front side, and the contour of the lower portion of the front side of the main body frame 10 is formed concentrically with the motor storage cylinder 7. The rear side of the 1 st side wall 11 is formed in a semicircular shape in side view while bulging rearward.

As described above, the counter case 40 is disposed above the 1 st side wall 11. The counter case 40 is screwed to the upper side of the 1 st side wall 11 by a fixing screw 70, and is screwed to the 1 st side wall 11. In the illustrated example, the counter case 40 is fixed by 2 fixing screws 70 arranged at intervals in the front-rear direction L2.

Various components (e.g., bearings, gears, receiving members, etc.) constituting the electric reel 1 are disposed in a portion of the first side wall 11 located rearward of the motor housing tube 7. Further, an edge 71 projecting toward the left side (LH) is continuously formed along the outer peripheral edge of the 1 st connecting wall.

The 1 st side wall 11 is formed with a connection screw 72 for attaching the 1 st side cover 21, a screw hole 73, and a receiving cylindrical portion 74.

As shown in fig. 5 and 6, the number of the connection screws 72 is 2 on the upper side of the 1 st side wall 11, and the 2 connection screws 72 sandwich the 2 fixing screws 70 to which the counter case 40 is attached and are separated in the front-rear direction L2. These connection screws 72 are attached from the side of the housing tube main body 60 so as to protrude toward the left side (LH). The number of the connection screws 72 is not limited to 2, and may be changed as appropriate.

The screw hole 73 is formed at a lower portion side of the 1 st side wall 11 at a central portion in the front-rear direction L2. The receiving cylinder portion 74 is a cylinder member having an internal cavity and opening to the Left (LH), and is formed in a portion of the 1 st side wall 11 located forward of the screw hole 73.

(electric motor)

As shown in fig. 7 and 9, the motor 8 has a motor output shaft 80 and a motor main body 81, wherein the motor output shaft 80 rotates about a motor axis O3; the motor main body 81 rotationally drives the motor output shaft 80, and the motor 8 is accommodated in the motor accommodating cylinder 7.

The motor output shaft 80 is disposed coaxially with the motor axis O3 so as to penetrate the motor main body 81 along the motor axis O3 direction. At this time, the motor output shaft 80 is formed to protrude to the Left (LH) side than the 1 st side wall 11 and to protrude to the Right (RH) side than the boss portion 64. In each drawing, the motor output shaft 80 is shown in a simplified diagram for illustration.

The motor output shaft 80 is stably rotatably supported by a plurality of bearings including a bearing 83 attached to the inside of the boss portion 64, for example. Further, an annular motor waterproof seal 84 is attached to a portion adjacent to the right side (RH) of the bearing 83 inside the boss portion 64. The inner peripheral edge portion of the motor waterproof seal 84 is in sliding contact with the entire circumference of the outer peripheral surface of the motor output shaft 80. Accordingly, entry of water, dust, or the like into the motor accommodating cylinder 7 is restricted.

At the left end portion of the motor output shaft 80, for example, a spline (zigzag groove portion) 85 is formed outside (left side (LH)) the 1 st side wall 11. The spline 85 is connected to a one-way clutch 86 attached to a motor bracket 9 described later. Accordingly, the rotation (reverse rotation) of the motor output shaft 80 in the fishing line releasing direction can be restricted. Therefore, the motor 8 is allowed to rotate only in one direction in which the fishing line is wound. The mounting position of the one-way clutch 86 is not limited to the motor holder 9, and may be changed as appropriate.

The motor main body 81 has a bottomed cylindrical box main body 81a and an end cap 81b, wherein the box main body 81a is opened toward the left side (LH); the end cap 81b closes the left opening of the cartridge main body 81 a. A connection wire 87 connecting the motor main body 81 and a motor control unit disposed in the counter case 40 is inserted through the end cap 81b at intervals in the circumferential direction, for example. In the illustrated example, the 2 connection wires 87 are arranged at equal intervals in the circumferential direction (specifically, arranged to face each other in the radial direction with the motor axis O3 interposed therebetween).

Further, the motor main body 81 mainly has, for example, a rotor having a coil and fixed to the motor output shaft 80, a stator, a commutator, and brushes; the stator has a permanent magnet, and is disposed in the casing main body 81a so as to surround the rotor from the outside in the radial direction.

The motor 8 configured as described above is electrically connected to a motor control unit via a connection wire 87 (see fig. 5), and the motor control unit controls driving of the motor 8.

Further, in a space of the motor housing cylinder 7 located on the right side (RH) of the bottom wall 61, for example, a speed reduction mechanism (not shown) or the like for reducing the speed of the rotational torque of the motor output shaft 80 and transmitting the rotational torque to the spool 4 is provided. The structure of the motor 8 may be changed as appropriate, and a brushless motor or the like may be used, for example.

(1 st side cover)

The 1 st side cover 21 will be described in detail.

As shown in fig. 1 to 4 and 10, the 1 st side cover 21 is formed to have a length in the front-rear direction L2 longer than a length in the vertical direction so as to correspond to the shape of the 1 st side wall 11, and is a cover member that covers the 1 st side wall 11 from the left side (LH). More specifically, the 1 st side cover 21 is assembled to the main body frame 10, covers the 1 st side wall 11 from the left side (LH), and covers the motor holder 9, the front cover 30, and a part of the counter case 40 attached so as to close the motor housing tube 7.

The 1 st-side cover 21 has a cover main body 90 and a peripheral edge portion 91, wherein the cover main body 90 is formed so as to bulge toward the left side (LH); the peripheral edge 91 is bent from the outer peripheral edge of the cover main body 90 toward the right side (the 1 st side wall 11 side) over the entire outer peripheral edge.

The peripheral edge 91 of the 1 st side cover 21 can be in contact with the edge 71 of the 1 st side wall 11, the side edge of the front cover 30, and the side surface of the counter case 40 without any gap. This makes it difficult for water, dust, and the like to enter the inside of the 1 st side cover 21. The peripheral edge 91 of the 1 st side cover 21 on the lower front side is formed concentrically with the motor accommodating cylinder 7 so as to match the main body frame 10.

Further, a screw receiving cylindrical portion 92 and a connection pin 93 are formed on the cover main body 90 so as to protrude toward the side wall 11 of the 1 st part, and a through hole 95 for inserting a connection screw 94 is formed.

The screw receiving cylindrical portion 92 is provided with 2 corresponding to the 2 connection screws 72 formed on the 1 st side wall 11, and is disposed at an interval in the front-rear direction L2 so as to face the connection screws 72 in the left-right direction L1. These screw receiving cylindrical portions 92 are cylindrical members having female screw portions formed on the inner peripheries thereof and opening to the right side (the 1 st side wall 11 side), and the connection screws 72 can be screwed thereto.

The connecting pin 93 is disposed so as to face the receiving cylindrical portion 74 formed in the 1 st side wall 11 in the left-right direction L1, and is formed so as to protrude to the Right (RH). The connecting pin 93 is formed in a cylindrical shape, for example, and can enter the receiving cylinder portion 74 formed in the 1 st side wall 11. The insertion hole 95 is disposed to face the screw hole 73 formed in the 1 st side wall 11 in the left-right direction L1, and is formed to penetrate the cover main body 90 in the left-right direction L1.

When the 1 st side cover 21 configured as described above is combined with the main body frame 10, the 1 st side wall 11 is covered from the left side (LH) while the connecting pin 93 is inserted into the receiving cylindrical portion 74 formed in the 1 st side wall 11. At this time, the insertion of the connecting pin 93 into the receiving tube portion 74 can guide the 1 st side cover 21 to appropriately combine the 1 st side cover 21 with the main body frame 10, and thus the side cover 20 can be easily and appropriately covered. After the 1 st cover 21 is placed over the main body frame 10, the connection screw 94 is screwed into the screw hole 73 from the left side (LH) of the 1 st cover 21 through the insertion hole 95, and the connection screw 72 is screwed into the female screw portion in the screw receiving tube portion 92 of the 1 st cover while penetrating the main body frame 10 from the right side (RH).

Accordingly, the 1 st side cover 21 can be screwed to the main body frame 10 with the peripheral edge portion 91 of the 1 st side cover 21 in contact with the edge portion 71 of the 1 st side wall 11, the side edge portion of the front cover 30, and the side surface of the counter case 40 without any gap.

Further, since the contour of the lower portion of the front portion side of the 1 st side cover 21 is formed in a substantially concentric circle shape with the motor accommodating cylinder 7, that is, the motor 8, the contour is formed in a shape corresponding to the shape of the motor 8 or the like, and a shape in which an unnecessary molded portion is eliminated can be obtained. Therefore, the appearance and design can be improved.

(electric motor support)

As shown in fig. 5 to 7, 11 and 12, the motor holder 9 is combined with the 1 st side wall 11 of the reel unit 2 so as to close the motor housing tube 7, and functions to fix the motor 8 to the reel unit 2.

The motor holder 9 has a lid body 100 having a top cylindrical shape and an engaging projection (engaging portion according to the present invention) 101, wherein the lid body 100 closes the opening 62 of the motor accommodating cylinder 7; the engaging projection is formed to project radially outward from the cover 100, and is engageable with an engaging recess (engaged portion according to the present invention) 120 formed in the 1 st side wall 11 in the circumferential direction.

The lid body 100 has a fitting cylinder 102 and a closing wall 103, wherein the fitting cylinder 102 is fitted inside the diameter-expanding cylinder 63 of the motor housing cylinder 7; the closing wall 103 closes the left opening of the fitting cylinder 102, and the lid 100 is disposed coaxially with the motor axis O3. A cylindrical housing tube 104 having a top projecting toward the left side (LH) is formed in the center portion of the closing wall 103 so as to be disposed coaxially with the motor axis O3. Accordingly, the lid body 100 is formed in a top tubular shape in which the central portion of the blocking wall 103 partially bulges toward the left side (LH).

An annular groove 105 recessed inward in the radial direction is formed on the entire outer peripheral surface of the fitting cylinder 102. An O-ring 106 (see fig. 7) is fitted in the annular groove 105 so as to be in close contact with the inner peripheral surface of the diameter-enlarging cylinder 63. Accordingly, the space between the fitting cylinder 102 and the enlarged diameter cylinder 63 can be appropriately sealed by the O-ring 106, and water, dust, or the like can be prevented from entering the motor housing cylinder 7 from the 1 st side wall 11 side.

The annular groove 105 may be formed on the inner circumferential surface of the expanding cylinder 63, for example, and need not be formed on the outer circumferential surface of the fitting cylinder 102. In this case, the space between the fitting cylinder 102 and the diameter-increasing cylinder 63 can be appropriately sealed by the O-ring 106.

The fitting cylinder 102 is not disposed entirely inside the enlarged diameter cylinder 63, but is partially a large diameter cylinder 107 disposed outside (left side (LH)) the enlarged diameter cylinder 63 and slightly enlarged in diameter. The outer peripheral edge of the blocking wall 103 is connected to the large-diameter tube 107. Further, the large diameter cylinder 107 contacts the 1 st side wall 11 from the left side (LH). Accordingly, the fitting cylinder 102 can be appropriately fitted into the enlarged diameter cylinder 63.

The closing wall 103 is formed with a through hole 108 for inserting the connection wire 87 connecting the motor 8 and the motor control unit therethrough so as to penetrate the closing wall 103. In the illustrated example, 4 through holes 108 are formed at equal intervals in the circumferential direction, and 2 connection wires 87 of the insertion end cap 81b are inserted through 2 of the through holes 108. Accordingly, the connection wire 87 can be wired between the motor 8 and the motor control unit.

Further, motor fixing screws 109 screwed into screw holes 109a (see fig. 9) formed in the end caps 81b are attached to the remaining two through holes 108. Accordingly, the motor main body 81 is fixed to the motor bracket 9.

Therefore, for example, after the motor holder 9 and the motor main body 81 are fixed to each other, the motor main body 81 can be accommodated in the motor accommodating tube 7. Fig. 9 illustrates a state in which the motor holder 9 is intentionally removed from the state shown in fig. 6.

The one-way clutch 86 described above is attached to the inside of the storage cylinder portion 104, and the left end portion of the motor output shaft 80 is stored therein.

The engaging protruding piece 101 is formed to protrude radially outward from the outer peripheral surface of the large-diameter tube 107. In the present embodiment, 2 engagement protruding pieces 101 are formed at equal intervals in the circumferential direction. That is, the engaging protruding piece 101 is composed of a 1 st engaging protruding piece 111 and a 2 nd engaging protruding piece 112. Accordingly, the 1 st engagement projection piece 111 and the 2 nd engagement projection piece 112 are arranged to face each other in the radial direction with the motor axis O3 interposed therebetween.

The 1 st engagement projection piece 111 and the 2 nd engagement projection piece 112 can be engaged with the 1 st engagement recess 120 formed in the 1 st side wall 11 in the circumferential direction, respectively.

The engaging recess 120 will be described.

As shown in fig. 6, 7, and 9, a 1 st engaging recess 121 that is recessed toward the Right (RH) is formed in a portion of the edge portion 71 of the 1 st side wall 11 that is located forward of the motor bracket 9. The 1 st engagement projection piece 111 is engaged in the circumferential direction by being fitted into the 1 st engagement recess 121 from the left side (LH).

Further, an engagement plug 125 is fixed to a portion of the 1 st side wall 11 located on the opposite side in the radial direction from the 1 st engagement recess 121 across the motor axis O3. The engaging plug 125 may be formed integrally with the 1 st side wall 11, or may be formed separately and combined with the 1 st side wall 11.

The engaging plug 125 has a base end 127 and an engaging claw 128, wherein the base end 127 is positioned on the 1 st side wall 11 by a positioning pin 126; the engaging claw portion 128 is formed in a bifurcated shape. The inside of the engaging claw portion 128 is a 2 nd engaging recess 122 that opens toward the motor holder 9 side. The 2 nd engaging protruding piece 112 is engaged in the circumferential direction by being fitted into the 2 nd engaging recessed portion 122 from the left side (LH). Further, a screw hole 129 is formed in the base end portion 127.

As described above, 2 engaging recessed portions 120 (i.e., the 1 st engaging recessed portion 121 and the 2 nd engaging recessed portion 122) are formed at intervals in the circumferential direction, and 2 engaging protruding pieces 101 (i.e., the 1 st engaging protruding piece 111 and the 2 nd engaging protruding piece 112) are configured to engage with the engaging recessed portions 120 in the circumferential direction.

As shown in fig. 13, the motor holder 9 configured as described above is configured to be restricted from moving in the motor axis O3 direction by being sandwiched between the 1 st side wall 11 and the 1 st side cover 21. Specifically, the 1 st side cover 21 is provided with a restricting projecting piece (a restricting member according to the present invention) 130, and the 1 st engaging projecting piece 111 is pressed from the left side (LH) between the restricting projecting piece 130 and the 1 st side wall 11, whereby the movement of the motor holder 9 to the motor axis O3 is restricted.

As shown in fig. 10, the restricting projecting piece 130 is formed so as to project from the inside of the peripheral edge portion 91 of the 1 st side cover 21 toward the 1 st engaging projecting piece 111, and when the 1 st side cover 21 is assembled to the main body frame 10 (see fig. 13), the 1 st engaging projecting piece 111 is pressed from the left side (LH). Accordingly, the 1 st engaging projection 111 can be prevented from coming off the 1 st engaging recess 121 by the restricting projection 130, and the movement of the motor holder 9 in the motor axis O3 direction can be restricted by sandwiching the entire motor holder 9 between the 1 st side wall 11 and the 1 st side cover 21.

In the present embodiment, as shown in fig. 5 to 7, a restricting screw 135 is provided to be screwed into a screw hole 129 formed in the base end portion 127 of the engagement plug 125, and the 2 nd engagement protruding piece 112 is pressed from the left side (LH) by the restricting screw 135. That is, the movement of the engaging projecting piece 101 (2 nd engaging projecting piece 112) in the motor axis O3 direction, which is different from the engaging projecting piece 101 (1 st engaging projecting piece 111) whose movement in the motor axis O3 direction is restricted by the restricted projecting piece 130, can be restricted by the restricting screw 135.

Specifically, the movement of the 2 nd engaging projection piece 112 in the motor axis O3 direction is restricted by the head of the restricting screw 135.

(function of electric fishing line reel)

Next, a case of using the electric reel 1 configured as described above will be described.

In the electric reel 1, a power supply reel wire electrically connected to an external power supply or a portable battery is electrically connected to the connector portion 23. Accordingly, electric power can be supplied to the motor 8, and the motor 8 can be driven.

Then, the clutch lever 5 is operated to set the clutch mechanism 6 to the clutch off state, whereby the spool 4 can be freely rotated, and the fishing line can be released and the hook assembly can be thrown into the water. Then, the clutch lever 5 is operated to switch the clutch mechanism 6 to the clutch engaged state, and the spool 4 is rotated by, for example, rotating the operating handle 3, thereby enabling manual winding operation of the fishing line. Alternatively, the operation switch 44 is operated to drive the motor 8 to rotate the spool 4, thereby enabling automatic winding of the fishing line.

Accordingly, fishing can be performed using the electric reel 1.

In addition, according to the electric reel 1 of the present embodiment, at the time of assembly, the motor holder 9 is combined with the 1 st side wall 11 so as to close the opening 62 of the motor housing tube 7 by the cover body 100, and then the 1 st side cover 21 is combined with the main body frame 10 so as to cover the 1 st side wall 11 as shown in fig. 1 to 4.

Accordingly, while the motor holder 9 is sandwiched between the 1 st side wall 11 and the 1 st side cover 21, as shown in fig. 13, the 1 st engagement projection piece 111 can be pressed from the left side (LH) by the restriction projection piece 130, and the movement of the motor holder 9 in the motor axis O3 direction can be restricted. Accordingly, the opening 62 of the motor storage cylinder 7 can be closed by the motor holder 9 while the movement of the motor holder 9 in the direction of the motor axis O3 is restricted.

Therefore, when the motor 8 disposed in the motor housing tube 7 is driven, the thrust load due to the driving is transmitted from the motor 8 to the motor holder 9, and the movement of the motor holder 9 in the direction of the motor axis O3 is restricted, so that the thrust load can be received.

As shown in fig. 6 and 7, the engaging protruding pieces 101 (i.e., the 1 st engaging protruding piece 111 and the 2 nd engaging protruding piece 112) of the motor holder 9 are circumferentially engaged with the engaging recesses 120 (i.e., the 1 st engaging recess 121 and the 2 nd engaging recess 122) formed in the 1 st side wall 11, respectively. Therefore, the movement of the motor holder 9 in the circumferential direction, that is, the movement of rotating about the motor axis O3 can be suppressed. Accordingly, even when the motor 8 is driven, the radial load about the motor axis O3 due to the rotational torque is transmitted from the motor 8 to the motor holder 9, and the radial load can be received.

In this way, the opening 62 of the motor housing tube 7 can be closed by the motor holder 9 while appropriately receiving the thrust load and the radial load from the motor 8, and therefore the motor 8 disposed in the motor housing tube 7 can be stably fixed.

In particular, when the motor holder 9 is incorporated in the reel unit 2, since fastening members such as screws and bolts are not required, a plurality of parts required for the fastening can be omitted. Therefore, the number of components can be reduced, which contributes to cost reduction and improvement in maintenance of the entire electric reel 1. Further, since it is not necessary to provide a space for installing a fastening member or a member such as a flange piece for fastening, the motor holder 9 can be easily designed compactly, which contributes to downsizing of the entire electric reel 1.

In particular, when the motor 9 is disposed below the front portion of the reel unit 10, as described above, the peripheral edge portion 91 of the 1 st-side cover 21 below the front portion is formed concentrically with the motor housing tube 7, so that an extra molded portion can be eliminated, and the appearance and design can be improved.

Therefore, the electric reel 1 according to the present embodiment can be reduced in size and the number of components, and can be used as an easy-to-use electric reel 1.

Further, since the motor holder 9 can be assembled by the engagement of the 1 st engaging recess 121 and the 1 st engaging protruding piece 111 and the engagement of the 2 nd engaging recess 122 and the 2 nd engaging protruding piece 112, the radial load transmitted from the motor 8 to the motor holder 9 can be received at a plurality of places (two places). Therefore, the posture of the motor holder 9 can be made more stable, and the motor 8 can be fixed more stably. Further, since the radial load is received at a plurality of portions (two portions), the load applied to the engaging portion at each portion can be reduced. Therefore, the motor holder 9 can be stably assembled for a long period of time, and thus can contribute to improvement in product reliability.

When the motor holder 9 is assembled to the 1 st side wall 11, the 1 st engaging protruding piece 111 and the 2 nd engaging protruding piece 112 can be circumferentially engaged with the 1 st engaging recess 121 and the 2 nd engaging recess 122 formed in the 1 st side wall 11. Accordingly, the motor holder 9 can be combined in a state in which the movement of rotation about the motor axis O3 is suppressed.

In particular, since the 1 st engaging recess 121 and the 2 nd engaging recess 122 are formed in the 1 st side wall 11 constituting the main body frame 10, the radial load transmitted from the motor 8 to the motor holder 9 can be shared by the main body frame 10 having high rigidity, and the posture of the motor holder 9 can be easily stabilized.

Further, since the movement of the 1 st engaging projection piece 111 itself in the motor axis O3 direction can be restricted by the restricting projection piece 130, the thrust load and the radial load transmitted to the motor bracket 9 can be effectively received by the 1 st engaging projection piece 111 at the same time.

In addition, since the movement of the 2 nd engaging projection piece 112 itself in the motor axis O3 direction can be restricted by the restricting screw 135, the thrust load and the radial load transmitted to the motor bracket 9 can be effectively received by the 2 nd engaging projection piece 112 at the same time.

While the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments may be implemented in other various manners, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. The embodiments and modifications thereof include, for example, the same forms, substantially the same forms, and equivalent ranges, which can be easily conceived by those skilled in the art.

For example, in the above embodiment, the description has been given taking as an example the type of the outside-bobbin motor in which the motor storage cylinder 7 is disposed in front of the bobbin 4, but the present invention is not limited to this case, and for example, the inside-bobbin motor type in which the motor storage cylinder 7 is provided inside the bobbin 4 may be used.

In the above embodiment, the case where the motor housing tube 7 is opened to the 1 st side wall 11 side as the right side grip type was described as an example, but the motor housing tube 7 may be opened to the 2 nd side wall 12 side as the left side grip type by contrast. In this case, the same effects can be exhibited.

In the above embodiment, the case where two engaging recesses 120 and two engaging protruding pieces 101 are formed is described as an example, but the present invention is not limited to this case, and for example, 1 engaging recess 120 and 3 or more engaging protruding pieces 101 may be formed.

Further, the number of the engaging recesses 120 does not need to be the same as the number of the engaging protruding pieces 101, and for example, 1 engaging protruding piece 101 may be formed, but 2 or more engaging recesses 120 may be formed. In this case, when the motor holder 9 is assembled to the 1 st side wall 11, for example, the engagement protruding piece 101 can be engaged with the engagement recess 120 selected according to the assembling state or the like. Therefore, the assembling can be easily performed, thereby contributing to an improvement in assembling efficiency.

In the above embodiment, the case where the engaging recess 120 is formed in the 1 st side wall 11 has been described as an example, but the present invention is not limited to this case, and it may be formed in the 1 st side cover 21. In this case, when the 1 st-side cover 21 is assembled to the main body frame 10, the engagement recess 120 and the engagement protruding piece 101 can be engaged in the circumferential direction, and therefore, the same operational effects can be exhibited.

However, as in the above-described embodiment, forming the engaging recess 120 in the 1 st side wall 11 is more preferable because it is possible to grasp that the engaging recess 120 and the engaging protruding piece 101 are appropriately engaged in the circumferential direction at the stage before the 1 st side cover 21 is assembled.

In the above embodiment, the movement of the motor holder 9 in the motor axis O3 direction is restricted by the restricting projection 130, but the present invention is not limited to this case, and for example, the movement of the motor holder 9 in the motor axis O3 direction may be restricted by the 1 st side cover 21 itself sandwiching the motor holder 9 between the 1 st side cover and the 1 st side wall 11.
