Abstract

The invention provides a thin battery box and a fishing reel with the same. By configuring the position of the O-ring (165C) to be arranged at a position overlapping with the button cell (200) in the height direction of the side portion (165AB) of the box main body (165A), the thickness of the entire battery box (165) can be suppressed compared with the case where the O-ring (165C) and the button cell (200) do not overlap. Further, with the structure in which the side portion (165BB) of the lid (165B) covers the side portion (165AB) of the box main body (165A) from the outside, even if the O-ring (165C) deteriorates and liquid enters between the side portion (165BB) and the side portion (165AB), the liquid does not reach the storage space of the box main body (165A) without reaching the upper end between the side portion (165BB) and the side portion (165AB), and therefore the liquid does not easily enter the storage space.

Description

Battery box of fishing reel for fishing and fishing reel for fishing

Technical Field

The present invention relates to a battery case for a fishing reel and a fishing reel.

Background

Some fishing reels have an electrical component that is operated by a battery. Examples of such electric elements include a sensor substrate for detecting rotation of a spool, a display device for displaying a depth of water in a fishhook assembly, and a control substrate for controlling the display device based on a detection result of the sensor substrate. The fishing reel having such an electric component mounted thereon has a battery case for storing a battery.

For example, patent document 1 discloses a battery cartridge having: a cartridge main body (a battery housing section 25 in patent document 1) forming a housing space for housing a battery; a cover (a cover member in patent document 1) of the cartridge main body, which covers the housing space; and a sealing member (gasket 54 in patent document 1) that prevents liquid from entering the housing space.

Disclosure of Invention

[ technical problem to be solved by the invention ]

In the battery case described in patent document 1, for example, the position of the gasket 54 is located below the battery, and therefore, the battery case is thick.

In view of the above circumstances, an object of the present invention is to provide a thin battery case and a fishing reel having the same.

[ technical means for solving problems ]

A battery pack (for example, battery pack 165) for a fishing reel according to a first aspect of the present invention includes: a cartridge main body (e.g., a cartridge main body 165A) having a bottom (e.g., a bottom 165AA) and a first side (e.g., a side 165AB) surrounding the bottom, a housing space (e.g., a housing space S) housing a battery (e.g., a button-type battery 200) being formed by the bottom and the first side; a cover (e.g., cover 165B) that covers the box main body in the storage space and has a second side portion (e.g., side portion 165BB) facing the first side portion; and a sealing member (e.g., an O-ring 165C) that is sandwiched between the first side portion and the second side portion at a position overlapping with the battery housed in the housing space in a height direction of the first side portion (e.g., see fig. 5), thereby preventing liquid from entering the housing space.

The sealing member is sandwiched between the first side portion and the second side portion at a position overlapping the battery in the height direction of the first side portion, whereby the thickness of the entire battery case can be suppressed. Thus, a thin battery case can be obtained. In particular, the battery case can be made thinner than in the case where the sealing member is sandwiched between the first side portion and the second side portion at a position not overlapping the battery in the height direction of the first side portion.

The first side portion and the second side portion may be both cylindrical, and the second side portion may be located outside the first side portion (see, for example, fig. 5).

With this configuration, even if the sealing member is deteriorated and the liquid enters between the first side portion and the second side portion, the liquid does not reach the housing space without advancing between the first side portion and the second side portion, and therefore the liquid does not easily enter the housing space.

In addition, a part of a battery terminal (for example, the positive electrode terminal 165D and the negative electrode terminal 165E) that contacts the electrode of the battery may be embedded in the case main body.

According to this configuration, the substrate for the battery terminal (the substrate on which the battery terminal is mounted) does not need to be provided, and the thickness of the battery case can be reduced to a thickness corresponding to the thickness of the substrate, thereby reducing the thickness of the battery case.

A fishing reel (for example, a dual-bearing reel 100) according to a second aspect of the present invention includes the battery pack of the fishing reel described above.

According to this configuration, a fishing reel having a thin battery box can be obtained, and the size of the housing portion of the battery box of the fishing reel can be reduced, for example.

[ Effect of the invention ]

According to the present invention, a thin battery case and a fishing reel having the battery case can be provided.

Detailed Description

Hereinafter, an embodiment in which the present invention is applied to a dual-bearing reel having a water depth counter will be described with reference to the drawings.

(Structure of Dual-bearing reel)

First, the structure of the dual-bearing reel 100 according to the present embodiment will be described with reference to fig. 1 to 5.

As shown in fig. 1 and the like, the dual-bearing reel 100 includes a reel leg 110, a first body 120, a handle 130, a spool 140, a clutch operating portion 150, a second body 160, and a connecting portion 170. The dual-bearing reel 100 is mounted to a fishing rod via reel legs 110. The dual-bearing reel 100 further includes a level winding mechanism (not shown) for uniformly winding the fishing line around the spool 140.

The first body 120 rotatably supports one end of the spool 140. Further, the handle 130 is attached to the first body 120, and the first body 120 includes a rotation transmission mechanism (not shown) for transmitting the rotation of the handle 130 to the spool 140 to rotate the spool 140. The rotation transmission mechanism is configured to include a plurality of gears, for example. The first body portion 120 further includes a clutch mechanism, a mechanical brake, a drag mechanism, and the like. The clutch mechanism transmits the rotation of the handle 130 to the spool 140 when in the engaged state, and does not transmit the rotation to the spool 140 when in the disengaged state. The engagement/disengagement of the clutch mechanism is switched by the clutch operating portion 150.

The second body 160 includes a case member 161, a cover 162, a bolt 163, a battery case 165 (fig. 2, etc.), a sensor board 166 (fig. 5), a ball bearing 167 (fig. 5), a mark 168 (fig. 2, etc.), and a sensor board housing 169 (fig. 2, etc.). The second body 160 further includes a plurality of gears for receiving the rotation of the spool 140 and rotating the worm shaft of the level winding mechanism. The plurality of gears may also be disposed within the first body portion 120.

As shown in fig. 5, a ball bearing 167 is disposed inside the case member 161, and the second body 160 rotatably supports the other end of the spool 140 (specifically, the other end 141A of the spool shaft (rotation shaft) 141 of the spool 140) by the ball bearing 167. The cover 162 has a dome shape, and is fastened and fixed to the case member 161 by a bolt 163 to cover the inside of the case member 161. The cover 162 can be detached from the case member 161 by detaching the bolts 163.

Battery compartment 165 houses button cell battery 200 (fig. 5). The detailed structure of battery case 165 will be described later together with reference numeral 168. The sensor substrate 166 mounts a magnetic sensor 166A (fig. 5). The plurality of magnets 142 (fig. 5) are provided on the bobbin 140, and the sensor substrate 166 detects the magnetism of any one of the plurality of magnets 142 (and thereby detects the rotation of the bobbin 140) by a magnetic sensor 166A (for example, constituted by a plurality of hall elements), and outputs an electric signal capable of specifying the rotation angle and the rotation direction of the bobbin 140 based on the detected magnetism. The sensor substrate accommodating section 169 accommodates the sensor substrate 166. The sensor board storage portion 169 is formed integrally with the cartridge main body 165A of the battery cartridge 165. The battery case 165, the sensor board 166, and the sensor board storage 169 are stored in an internal space formed by the case member 161 and the cover 162 (fig. 5 and the like). The case member 161 and the cover 162 constitute a case of the dual-bearing reel 100 (particularly, the second body 160).

The coupling portion 170 couples the first body portion 120 and the second body portion 160, which are spaced apart from each other with the bobbin 140 interposed therebetween. The connection portion 170 includes a display device 171, a power/reset button 172, and a control board 173 (not shown in fig. 6 and fig. 1 to 5). The display device 171 is a liquid crystal display device or the like, and displays the current water depth (the length of the fishing line to be paid out) of the fishing hook assembly for fishing. The power/reset button 172 is used to start (power on) or end (power off) the display of the water depth of the hook assembly, or to reset. The control board 173 is mounted inside the connection portion 170. The control board 173 includes a processor such as a microcomputer, and the control of the display device 171 and the like are performed by the processor.

The display device 171, the power/reset button 172, and the control board 173 constitute a water depth counter (hereinafter referred to as a water depth counter C) together with the sensor board 166 of the second body 160. The electrical structure of the water depth counter C is shown in fig. 6. The water depth counter C operates by a button cell 200 housed in the battery case 165. The control board 173 (processor) determines the length of the fishing line paid out from or wound around the spool 140 based on the electric signal from the sensor board 166, and increases or decreases the current water depth of the hook assembly displayed on the display device 171 based on the determined length. When the power/reset button 172 is pressed, an operation signal indicating that the pressing operation is performed is supplied to the control board 173. The control board 173 is activated (power is turned on), or deactivated (power is turned off), or resets the current water depth of the hook assembly displayed on the display device 171 (reset of the water depth display) (for example, when the time is short, the power is turned on or off, and when the time is long, the water depth is reset).

Referring back to fig. 1 to 5, the detailed structure of battery case 165 will be described. In the following description, the direction of the cover 162 (left side when viewed from a user of a fishing rod to which the dual-bearing reel 100 is attached) is referred to as "up", and the direction of the spool 140 (right side when viewed from the user) is referred to as "down".

As shown in fig. 2 and the like, the battery case 165 includes a case main body 165A, a lid 165B, O-shaped ring 165C (omitted in fig. 3), a positive electrode terminal 165D (omitted in fig. 5 and other figures), and a negative electrode terminal 165E (fig. 5). Battery case 165 is disposed in cover 162, and protrudes from the periphery when cover 162 is removed.

The cartridge main body 165A includes: a rounded bottom 165 AA; a cylindrical side portion 165AB extending upward from the bottom portion and surrounding the bottom portion 165 AA; and three groove forming portions 165AC which protrude upward from the side portions 165AB and form bayonet grooves BM. The bottom 165AA and the side 165AB form a storage space S for storing the button cell 200. Three bayonet projections 165BD (fig. 3) described later enter the respective bayonet grooves BM of the three bayonet grooves BM one by one. The surface of the lower side of the bayonet groove BM is formed coplanar with the upper surface of the side portion 165 AB. Further, the respective upper surfaces of the groove forming portions 165AC have: a first upper surface TP1 which is a surface of a side where the bayonet projection 165BD enters the bayonet groove BM; and a second upper surface TP2, which is a surface of a side opposite to a side where the bayonet protrusions 165BD enter the bayonet groove BM, and is connected with an upper surface of the side portion 165AB downward from the first upper surface TP 1.

The case main body 165A is made of synthetic resin, and is embedded in a part of the positive electrode terminal 165D and a part of the negative electrode terminal 165E, and is formed integrally with the positive electrode terminal 165D and the negative electrode terminal 165E. The cartridge main body 165A is formed by insert molding in which the positive electrode terminal 165D and the negative electrode terminal 165E are inserted, for example. In addition, in order to prevent short-circuiting or the like, an unnecessary portion may be covered with an insulator for each of the positive electrode terminal 165D and the negative electrode terminal 165E.

The cover 165B is a bayonet cover that can be attached to and detached from the cartridge main body 165A by rotation. The cover 165B has a covering portion 165BA, a side portion 165BB, three projections 165BC, and three bayonet projections 165 BD.

The covering portion 165BA has a disk shape, and covers the storage space S of the cartridge main body 165A from above. Side portion 165BB has a cylindrical shape extending downward from covering portion 165BA and surrounding covering portion 165BA, and faces side portion 165AB of cartridge main body 165A and covers side portion 165AB from the outside. The covering portion 165BA and the side portion 165BB constitute a cap body which has a circular cup shape as a whole and is capped on the cartridge body 165A.

The three projections 165BC project outward from the outer peripheral surface of the side portion 165BB (in the direction perpendicular to the rotation axis of the cover 165B (the two-dot chain line passing through the center of the cover 165B in fig. 2), in the lateral direction perpendicular to the vertical direction, in the radial direction of the cover 165B). The three protrusions 165BC are disposed on the outer peripheral surface of the side portion 165BB at equal intervals every 120 degrees. The projection 165BC is formed in a shape that can be hooked by a user's finger when the cover 165B is rotated for attachment or detachment. The protrusion 165BC has a mountain shape to correspond to the user's finger.

The three bayonet projections 165BD project inward from the inner peripheral surface of the side portion 165 BB. The bayonet projection 165BD enters the bayonet groove BM of the cartridge main body 165A. The cover 165B is thereby attached to the cartridge main body 165A by engaging the two.

As shown in fig. 5, the O-ring 165C is sandwiched by the side 165AB of the cartridge main body 165A and the side 165BB of the cover 165B. The O-ring 165C is disposed at a position overlapping the button cell 200 housed in the housing space S in the height direction (vertical direction) of the side portion 165AB of the case main body 165A. Specifically, the O-ring 165C is disposed within the thickness H of the button cell 200 housed in the housing space S (fig. 5). The O-ring 165C is a sealing member for preventing a liquid such as water (including seawater) from entering the cartridge main body 165A. The height direction of the side portion 165AB of the case main body 165A is also the rotation axis direction of the cover 165B, the center axis direction of the side portion 165AB, the height direction of the side portion 165BB, the thickness direction of the case main body 165A (or the button cell 200), and the like.

Positive terminal 165D is in contact with the positive electrode of button cell 200. Negative terminal 165E is in contact with the negative electrode of button cell 200. One of the positive electrode terminal 165D and the negative electrode terminal 165E is connected to the control board 173 via the sensor board 166, and the other of the positive electrode terminal 165D and the negative electrode terminal 165E is directly connected to the control board 173 via a wiring not shown. Accordingly, the power supply to the sensor substrate 166 is controlled by the control substrate 173.

The mark 168 is a triangular shape and is formed by printing or the like around the cover 165B attached to the cartridge main body 165A. When the cover 165B is attached to the cartridge main body 165A, the mark 168 is disposed at a position where one of the three protrusions 165BC comes to the position of the mark 168.

(attachment/detachment of cover of Battery case)

Next, the operation when the user attaches the cover 165B to the cartridge main body 165A and when the cover 165B is detached from the cartridge main body 165A will be described.

When attaching the cover 165B to the cartridge main body 165A, the user first lightly holds the cover 165B and covers the cartridge main body 165A. Next, the user hooks the fingers to the projections 165BC from the right side when viewed from above (for example, hooks the thumb to one of the three projections 165BC, the index finger to the other, and the middle finger to the last), and rotates the cover 165B counterclockwise. When the user rotates the cover 165B to some extent, the bayonet projection 165BD enters the bayonet groove BM of the groove forming portion 165AC, and reaches the end of the bayonet groove BM. At this time, since the bayonet projection 165BD is engaged with the bayonet groove BM, the cover 165B is attached to the cartridge main body 165A. At this time, one of the protrusions 165BC is located at a position corresponding to the mark 168. That is, the user may rotate the cover 165B with the mark 168 as a target. In this way, the mark 168 can report the rotational position of the cover 165B (whether the rotational position of the cover 165B is the position attached to the cartridge main body 165A, etc.) with reference to the relative position with respect to the bayonet projection 165 BD.

Further, when the lid 165B is put on the cartridge main body 165A, the bayonet projection 165BD may contact the upper surface of the groove forming portion 165AC, but even in this case, the user rotates the lid 165B while applying downward force, and the bayonet projection 165BD can slide on the upper surface of the groove forming portion 165AC, and then reach the upper surface of the side portion 165AB, and then enter the bayonet groove BM. In this embodiment, the bayonet projection 165BD can smoothly reach the upper surface of the side portion 165AB particularly by the second upper surface TP2 which is an inclined surface that is connected downward from the first upper surface TP1 to the upper surface of the side portion 165 AB. Further, since the upper surface of the side portion 165AB and the lower surface of the inside of the bayonet groove BM are coplanar, the bayonet projection 165BD can finally reach the bayonet groove BM smoothly.

When detaching the cover 165B from the cartridge main body 165A, first, the user hooks his or her finger on the protrusion 165BC from the left side when viewed from above, and rotates the cover 165B clockwise. When the user rotates the cover 165B to some extent, all the portions of the bayonet projections 165BD are not engaged with the bayonet grooves BM. The user can pull the cover 165B upward from this state, and thereby detach the cover 165B from the cartridge main body 165A.

When the lid 165B is detached from the cartridge main body 165A, the lid 165B can be smoothly detached from the cartridge main body 165A because the bayonet projections 165BD reach the inclined surface, i.e., the second upper surface TP2, when the lid 165B is continuously rotated.

(effects of the embodiment)

Since the user can rotate the cover 165B by hooking a finger on the protrusion 165BC, the cover 165B can be attached to the cartridge main body 165A or detached from the cartridge main body 165A without using a coin or a tool. In this embodiment, instead of providing a groove (e.g., coin groove) or a recess for inserting coins or tools into the cover 165B, a protrusion 165BC protruding outward (in a direction orthogonal to the rotation axis of the cover 165B) from the outer peripheral surface of the side portion 165BB is provided, so that the thickness of the cover 165B (the length in the vertical direction of the battery case 165) can be suppressed as compared with the case where the groove or recess is provided. Thus, according to this embodiment, the thickness of battery case 165 can be reduced.

Further, the cover 165B has: a covering portion 165BA that covers a storage space S formed by a bottom portion 165AA of the cartridge main body 165A and a cylindrical side portion 165AB surrounding the bottom portion 165AA from above; and a cylindrical side portion 165BB covering the side portion 165AB from the outside, and the protruding portion 165BC protrudes from the side portion 165BB, so that the user can easily operate the cover 165B. The thickness of the cover 165B is substantially the sum of the thickness of the covering portion 165BA and the height of the side portion 165AB (the length of the battery case 165 in the vertical direction). The thickness of the covering portion 165BA can be suppressed, and the thickness of the cap can be suppressed. Accordingly, the thickness of the battery case 165 can be suppressed.

In addition, in the battery case 165, the case main body 165A and the cover 165B are mounted by the bayonet method, and therefore, the rotation angle required for mounting and dismounting the cover 165B is reduced. Accordingly, the user can easily attach and detach the cover 165B, for example, as compared with the case of the screw connection method.

In addition, even if the bayonet projection 165BD contacts the upper surface of the groove forming portion 165AC when the cover 165B is attached to the cartridge main body 165A, the bayonet projection 165BD can smoothly reach the upper surface of the side portion 165AB by the second upper surface TP2 and smoothly enter the bayonet groove BM as described above. When the lid 165B is detached from the cartridge main body 165A, the lid 165B can be smoothly detached because the bayonet projection 165BD reaches the inclined surface, i.e., the second upper surface TP2, when the lid 165B is continuously rotated. As described above, battery case 165 provides a good operational feeling when lid 165B is attached or detached.

In addition, since battery case 165 is covered with cover 162, the waterproof property and design property relating to this portion are improved. Battery case 165 is housed in dome-shaped cover 162, and when cover 162 is removed, battery case 165 protrudes from the periphery. Accordingly, the user can easily hook the finger on the protrusion 165 BC.

By providing the mark 168, the user can know where the cover 165B is rotated well by comparing the protrusion 165BC with the mark 168.

The thickness of the entire battery case 165 can be suppressed by the following structure: the side portion 165AB of the case main body 165A and the side portion 165BB of the cover 165B are opposed to each other, the O-ring 165C is sandwiched between the side portion 165AB and the side portion 165BB of the cover 165B, and the O-ring 165C is disposed at a position overlapping the button cell 200 in the height direction of the side portion 165AB of the case main body 165A. If the O-ring 165C and the button cell 200 do not overlap in the height direction, the entire battery case 165 becomes thicker, but if the O-ring 165C and the button cell 200 overlap, the entire battery case 165 can be made thinner than if the O-ring 165C and the button cell 200 do not overlap.

Further, with the structure in which the side portion 165BB of the cover 165B covers the side portion 165AB of the box main body 165A from the outside, for example, even if the O-ring 165C is deteriorated and the liquid enters between the side portion 165BB and the side portion 165AB and does not reach the upper end between the side portion 165BB and the side portion 165AB, the liquid does not easily enter the storage space S because it does not reach the upper end.

Since a part of the positive electrode terminal 165D and a part of the negative electrode terminal 165E are embedded in the case main body 165A, it is not necessary to provide a substrate for the positive electrode terminal 165D and the negative electrode terminal 165E (a substrate on which each terminal is mounted) in the case main body 165A. With this configuration, the thickness of the battery case 165 can be reduced so as to reduce the thickness of the substrate for the positive electrode terminal 165D and the negative electrode terminal 165E. Further, as shown in this embodiment, this structure is a structure that is easy to adopt when the cartridge main body 165A and the sensor substrate housing portion 169 are integrally formed (this is because it is easy to wind the wiring from the positive electrode terminal 165D or the negative electrode terminal 165E around the sensor substrate 166).

(modification example)

The present invention is not limited to the above embodiment, and various other modifications may be made. For example, the shapes of the above-described members and the like may be arbitrarily changed. The present invention can be applied to a spinning reel and the like as long as the battery is mounted.

The O-ring 165C and the button cell 200 are not limited as long as they are overlapped in the height direction of the side portion 165AB of the case main body 165A. The two may also partially overlap.

The number of the projections 165BC of the cover 165B is arbitrary. The shape of the protruding portion 165BC may be a shape that can be hooked by a finger of the user. The projection 165BC may be used only when the cover 165B is attached to or detached from the cartridge main body 165A (for this reason, the shape may be changed). Both the attachment projection 165BC and the detachment projection 165BC may be provided.
