Description

  The present invention relates to a battery mounting structure for mounting a battery on a vehicle body.

  Vehicles such as two-wheeled vehicles and four-wheeled vehicles are equipped with various electrical devices such as electric components such as headlamps, blinkers, and immobilizers, and electric cell motors. These electric devices are connected to a battery, and power is supplied from the battery. The battery is mounted, for example, under the seat of a motorcycle, and various structures are known to mount the battery at that position. For example, a vehicle body center structure such as Patent Document 1 and Patent Document 2 are known. The assembly structure is as follows.

  In the vehicle body central part structure of Patent Document 1, the battery is located under the seat and is arranged in parallel with the front side of the air cleaner. Further, the battery is arranged close to the left side on the opposite side in the vehicle width direction with respect to the exhaust pipe so as to avoid the influence of high heat generated by the exhaust pipe. Therefore, the battery is exposed in the vehicle width direction and can be taken out from the vehicle width direction.

  The assembly structure of Patent Document 2 is located under the seat of a motorcycle and has a box body and a body frame. The box body can be accommodated by inserting a battery therein. The vehicle body frame is formed with an accommodation opening for inserting the box body, and a recess for accommodating the box body is formed below the accommodation opening. The storage port must be tilted forward until the box body is tilted forward. The box body that is tilted forward and placed in the storage port is moved forward until the entire bottom surface of the box body enters the storage port. It is pushed in diagonally downward, and it is accommodated in a recessed part by lowering after the whole bottom face is settled in the accommodation port. Further, a seat is placed on the body frame, and the accommodation opening is closed by this seat.

  In the vehicle body center part structure described in Patent Document 1, the battery can be taken out in the vehicle width direction, but the battery is exposed. Therefore, it is preferable to cover the battery with the side cover from the viewpoint of theft prevention. However, the side cover cannot be easily removed from the vehicle body frame due to the structure of the vehicle. This substantially complicates the battery attaching / detaching operation. On the other hand, in the assembly structure described in Patent Document 2, since the accommodation opening is closed with the seat, the battery can be prevented from being stolen, and the seat can be easily removed from the vehicle body frame by unlocking with the key. Therefore, the battery can be easily attached and detached as compared with the vehicle body central structure disclosed in Patent Document 1.

  However, in the assembly structure described in Patent Document 2, the box body must be tilted forward when the battery is inserted into the storage port, and the box body must be pushed in when stored in the recess. Although the storage port is lowered in height by the assembly structure, the storage port is under the seat, and the storage port is at a high position. In such a position, the work of tilting and pushing the box body containing the heavy battery is difficult. Further, since the battery is disposed so that the longitudinal direction of the battery is parallel to the width direction of the vehicle body, the battery is disposed near the exhaust pipe. Therefore, the battery may be adversely affected by the high heat generated by the exhaust pipe.

  Accordingly, an object of the present invention is to provide a battery mounting structure that is easy to mount a battery and can prevent theft.

  A battery mounting structure according to the present invention is for mounting a battery on a vehicle body, and includes a frame of the vehicle body, a battery storage space formed inside the vehicle body from the frame and capable of storing the battery, and the frame A battery inlet / outlet that is opened upward and surrounded by the battery housing space, and the battery inlet / outlet is inserted with the longitudinal direction of the battery parallel to the vehicle width direction of the vehicle body.

Hereinafter, the battery mounting structure 1 will be described with reference to FIGS. 2 to 4, in order to make the battery mounting structure 1 easier to see, the configuration provided in the motorcycle 2, for example, the engine E, the seat 15, and the side cover 43 are shown removed.

  The battery mounting structure 1 includes a motorcycle 21 that supplies electric power to various electric devices (not shown) such as an electric component (not shown) such as a headlamp, a winker, and an immobilizer, and an electric cell motor. It is a structure for accommodating and mounting. The battery mounting structure 1 is provided with the battery case 22 which accommodates the battery 21 formed in the substantially rectangular parallelepiped shape, as shown in FIGS. The battery case 22 is configured to accommodate the battery 21 and is integrally formed with a rear fender that covers the rear wheel 12 (see FIG. 1). The battery case 22 has a case body 23 and a fender portion 24.

  The case main body 23 is a substantially rectangular parallelepiped thin-walled box, and has walls on the front, rear, left and lower sides, and the upper and right sides are open. The case body 23 having such a shape is located below the seat rail 14 and inside the pair of seat rails 14 in a plan view. That is, the case main body 23 is located inside the motorcycle 2 in the frame 7. The silencer 19 is located on the right side of the case body 23 arranged in this way, and the case body 23 is easily affected by the heat of the silencer 19. However, by opening the right side of the case body 23, the heat of the silencer 19 is prevented from propagating to the case body 23 and the temperature of the case body 23 is prevented from rising. Thereby, it is possible to prevent the case body 23 from being melted by heat.

  Moreover, the case main body 23 has the front side attaching part 26 in the upper end part of the front wall 23a. The front attachment portion 26 is a plate member extending in the vehicle width direction, protrudes forward from the upper end portion of the front wall 23 a, and is attached to the front bracket 27. The front bracket 27, which is a part of the frame 7, is a plate-like member extending in the vehicle width direction and is installed on the pair of seat rails 14. The front mounting portion 26 is applied to the front bracket 27 from below and is fixed by bolts or welding. Further, the lower end portion of the front wall 23a is chamfered so as to avoid the rear suspension 20 and is inclined rearward and obliquely downward, and an inclined portion 23b is formed by this portion.

  Further, the rear wall 23c of the case body 23 is higher than the front wall 23a, and has a rear attachment portion 28 at the upper end portion thereof. The rear attachment portion 28 is a plate-like member extending in the vehicle width direction, and is formed so as to protrude rearward and obliquely upward from the upper end portion of the rear wall 23c. The rear attachment portion 28 is attached to the rear bracket 29. The rear bracket 29, which is a part of the frame 7, is a member extending in the vehicle width direction. The rear bracket 29 is positioned rearward from the front bracket 27 and is installed on the pair of seat rails 14. The rear attachment portion 28 is applied to the rear bracket 29 from below and is fixed by bolts or welding. Further, the fender portion 24 is provided integrally with the rear attachment portion 28. The fender portion 24 extends from the rear attachment portion 28 on its extension line, that is, obliquely upward to the rear, and is curved so as to be lowered on the rear end side of the fender portion 24 so as to cover the rear wheel 12.

  The case main body 23 thus configured has a battery housing space 25 therein. The battery housing space 25 is closed by the wall of the case body 23 at the front, rear, left and lower sides, and the upper side and the right side are opened. The battery housing space 25 is located below the seat rail 14 and inside the pair of seat rails 14 in a plan view. That is, the battery housing space 25 is located inside the motorcycle 2 in the frame 7. Further, the battery housing space 25 has a substantially rectangular parallelepiped shape, and the front-rear direction is longer than the vehicle width direction. The battery housing space 25 having such a shape is opened upward by the upper opening of the case body 23. The upper opening has a rectangular shape in plan view, and the cross pipe 30 overlaps a partial region thereof.

  The cross pipe 30 is a cross member that supports a seat frame 31 constituting a part of the seat 15 from below. The cross pipe 30 is a cylindrical pipe member extending in the vehicle width direction, and is installed on the pair of seat rails 14. The cross pipe 30 is disposed between the front bracket 27 and the rear bracket 29 in plan view, and is surrounded by the pair of seat rails 14 between the cross pipe 30 and the rear bracket 29. A battery inlet / outlet 32 (indicated by a thick line in FIG. 2) that opens upward is formed.

  The battery inlet / outlet 32 is formed in a substantially rectangular shape, and the length in the vehicle width direction of the battery inlet / outlet 32 (that is, the battery inlet / outlet 32) from the length in the front-rear direction (that is, the length of the battery inlet / outlet 32) d2. The width d1 is longer. The length d2 of the battery inlet / outlet 32 is longer than the length in the short direction of the battery 21 in plan view, and the width d1 of the battery inlet / outlet 32 is longer than the length of the battery 21 in the longitudinal direction. As a result, the battery inlet / outlet port 32 is placed from the battery inlet / outlet port 32 into the battery housing space 25 by making the posture of the battery 21 sideways (insertion posture, see reference numeral 21A in FIG. 2) whose longitudinal direction is parallel to the vehicle width direction. The battery 21 can be taken in and out. On the other hand, when the posture of the battery 21 is vertical (for example, the posture shown by the solid line in FIG. 2) in which the longitudinal direction is substantially parallel to the front-rear direction, the battery inlet / outlet 32 can not take in and out the battery 21. Yes. That is, the length d2 of the battery inlet / outlet 32 is shorter than the length of the battery 21 in the longitudinal direction.

  In the battery housing space 25, the battery 21 is housed in a vertical orientation (mounting posture) indicated by a solid line in FIGS. 2 to 4 and arranged close to the left wall 23 d and the front wall 23 a of the case body 23. Yes. By approaching the left wall 23d in this manner, the battery 21 is arranged offset to the left from the center L1 in the vehicle width direction of the motorcycle 2 and arranged away from the silencer 19 (muffler 17) arranged on the right side in the vehicle width direction. Is done. Thereby, it is possible to suppress the influence of heat generated from the silencer 19, for example, the shortening of the life of the battery 21. Further, as shown in FIG. 2, the battery 21 is moved toward the front wall 23a until the front lower end contacts the inclined portion 23b, and the position in the front-rear direction is determined by the inclined portion 23b. Yes. Thus, the battery 21 is mounted at the mounting position brought close to the left wall 23d and the front wall 23a.

  In order to arrange the battery 21 inserted laterally from the battery inlet / outlet 32 in such a mounting posture and mounting position, the case body 23 rotates the battery 21 around an axis perpendicular to the front-rear direction and the vehicle width direction. The posture and position of the battery 21 can be changed by being moved. In the present embodiment, the battery 21 is rotated while a part of the right side of the battery 21 is exposed from the right side opening of the case body 23 (see reference numeral 21B in FIG. 2), and the long side of the battery 21 is parallel to the front-rear direction. The posture can be changed and the left wall 23d and the front wall 23a can be brought close to each other. By forming the opening on the right side of the case main body 23 in this way, the battery 21 can be rotated even if the width of the case main body 23 is short, so that the case main body 23 can be reduced in size.

  The battery 21 has an anode terminal 21a and a cathode terminal 21b on the upper surface thereof. These two terminals 21a and 21b are located apart from each other in the longitudinal direction. When rotating the battery 21, the bottom surface of the case body 23 is positioned below the cross pipe 30 by at least the height of the battery 21 so that the two terminals 21 a and 21 b do not hit the cross pipe 30. ing. As shown in FIG. 3, the rotated battery 21 is accommodated in an accommodating position in which the anode terminal 21a is located on the rear side and the cathode terminal 21b is located on the front side, as shown in FIG. Further, damper members 33 a to 33 c are provided on the inner surfaces of the left wall 23 d and the front wall 23 a of the case body 23.

  The damper members 33a to 33c are plate-like shock absorbing members made of an elastically deformable synthetic resin. Two damper members 33a to 33c are provided inside the left wall 23d and one inside the front wall 23a. The damper members 33a and 33b are fixed to the left wall 23d so as to be separated from each other in the front-rear direction and support a part of the left side surface of the battery 21 at the mounting position. The damper member 33c is fixed to the front wall 23a and abuts and supports a part of the front surface of the battery 21 at the mounting position. As described above, the damper members 33a to 33c that contact and support the battery 21 are disposed on the inner side (that is, the inner surface) of the left wall 23d and the front wall 23a of the case body 23 with a space therebetween. Therefore, the heat of the battery 21 can be dissipated from between the damper members 33a to 33c, and the temperature rise of the battery 21 can be suppressed. Thereby, generation | occurrence | production of the malfunction resulting from the temperature rise of the battery 21 can be suppressed. Further, the right side surface, the rear surface, and the upper surface of the battery 21 are supported by a fixed cover 34.

  The fixed cover 34 is made of synthetic resin or the like, and is provided in the battery housing space 25. The fixed cover 34 has a right support part 35. The right support part 35 is a plate-like member having substantially the same outer diameter as the right side surface of the battery 21, and has a case side mounting plate 35 a at the middle part in the front-rear direction of the lower end part of the right support part 35. The case side mounting plate 35a extends rightward from the lower end portion of the right support portion 35, and is fixed to the bottom surface 23e of the case body 23 by a fastening member such as a bolt.

  The fixed right support portion 35 is disposed orthogonal to the vehicle width direction, extends forward from the battery inlet / outlet 32, and intersects the cross pipe 30 in plan view. The right support portion 35 arranged in this way is located along the right side surface of the battery 21, and a support surface 35 b that is one surface of the right support portion 35 faces the right side surface of the battery 21. Two protrusions 35c are formed on the support surface 35b. The protruding portion 35c, which is a protruding portion, is located at a distance in the front-rear direction, protrudes toward the left wall 23d of the case body 23 (that is, the right side surface of the battery 21), and extends in the vertical direction. ing. These protrusions 35c abut on and support the right side surface of the battery 21, press the battery 21 against the damper members 33a and 33b of the left wall 23d, and hold the battery 21 together with them. The right support part 35 is provided with a rear support part 36 and an upper cover part 37.

  The rear support portion 36 is integrally formed with the rear end portion 35d of the right support portion 35, and extends from the rear end portion 35d to the middle of the rear surface of the battery 21 toward the left wall 23d. The front surface of the rear support portion 36 having such a shape covers a region from the rear right corner of the battery 21 to the middle of the rear surface thereof, and a ridge portion 36a is also formed there. The protruding portion 36a, which is a protruding portion, protrudes toward the left wall 23d of the case main body 23 (that is, the right side surface of the battery 21), and extends in the vertical direction. The protruding portion 36a abuts and supports the rear surface of the battery 21, presses the battery 21 against the damper member 33c of the front wall 23a, and holds the battery 21 together with them.

  Thus, even if the storage position of the battery 21 is slightly shifted or the processing accuracy of the case main body 23 is low by being sandwiched between the damper members 33a to 33c and the protruding portions 35c and 36a, The damper members 33a to 33c are deformed according to the position of the battery 21 and the shape of the case main body 23, so that the battery 21 can be securely held at the mounting position. That is, by providing the damper members 33a to 33c, the positional deviation of the battery 21 and the processing accuracy of the case main body 23 are absorbed, and the battery 21 can be held firmly. Similarly to the damper members 33a to 33c, the protrusion portions 35c and 36a are formed at intervals in the right side support portion 35 and the rear side support portion 36 of the fixed cover 34. The heat of 21 can be dissipated, and the temperature rise of the battery 21 can be suppressed. The same effect can be obtained by providing the damper members 33 a to 33 on the fixed cover 34 and the protrusions 35 c and 36 a on the case body 23.

  The upper cover portion 37 is integrally formed at the middle portion in the front-rear direction of the upper end portion of the right support portion 35, and extends from there to the left wall 23d. The upper cover portion 37 is a plate-like member and overlaps the battery 21 in a plan view, and prevents the battery 21 from being lifted. A frame side attachment portion 38 is formed at the left end portion of the upper cover portion 37. The frame side attachment portion 38 extends upward from the left end portion of the upper cover portion 37, and the upper end portion thereof is fixed to the seat rail 14 by a fastening member (not shown) such as a bolt.

  In the fixed cover 34 fixed in this way, the right support portion 35 is disposed along the right side surface of the battery 21, and the outer diameter dimension thereof is substantially the same as the outer diameter dimension of the right side surface. The right side surface (long side in plan view) 21 can be supported by a wide surface, and the movement of the battery 21 in the vehicle width direction can be securely prevented. In order to support the right side surface of the battery 21 with such a wide surface, the right side support portion 35a intersects the cross pipe 30, but the rear side support portion 36 is connected to the rear surface of the battery 21 (short side in plan view). ), The fixed cover 34 is inclined and the front end portion of the right support portion 35 is hidden under the cross pipe and pushed along the right side surface of the battery 21 as will be described later. Since it can be inserted into the battery housing space 25 and attached thereto, the attachment is easy.

  An igniter 39, which is an electronic ignition device, is accommodated in the battery accommodating space 25, and an igniter mounting bracket 40 for attaching the igniter 39 is provided at an intermediate portion in the vehicle width direction of the upper cover portion 37. . The igniter mounting bracket 40 is integrally formed with the upper cover portion 37, and includes a support portion 40a and a mounting portion 40b. The support portion 40a and the attachment portion 40b are both plate-like members, the support portion 40a extends rearward from the upper cover portion 37, and the attachment portion 40b extends upward from the tip end portion of the support portion 40a. Exist. Accordingly, the igniter mounting bracket 40 is formed in an L shape in a side view. A mounting member 41 formed in a U shape in a plan view is provided on the front surface of the igniter 39 with its opening directed toward the igniter 39. The mounting member 41 is mounted between the mounting member 41 and the igniter 39. A hole 42 is formed. The igniter 39 is mounted by inserting the mounting portion 40 b of the igniter mounting bracket 40 through the mounting hole 42.

[Battery mounting method]
Hereinafter, a method for mounting the battery 21 on the battery mounting structure 1 will be described. First, in the motorcycle 2, the seat 15 placed on the seat rail 14 and locked by a lock mechanism (not shown) is removed, and the battery entrance 32 is exposed. Next, the battery 21 is inserted into the battery housing space 25 from the battery inlet / outlet 32. At this time, the battery 21 is placed sideways so that the battery 21 overlaps the battery inlet / outlet 32 in a plan view, and the cathode terminal 21 b is arranged on the left side, and the battery 21 is inserted into the battery inlet / outlet 32. The battery 21 is straightly lowered and placed on the bottom surface 23e of the case body 23, and then the battery 21 is rotated 90 degrees clockwise to be in a vertical orientation.

  At this time, the cathode terminal 21b arranged on the left side in the horizontal direction passes under the cross pipe 30 and is arranged in front of the anode terminal 21a. Since the cross pipe 30 is grounded via the front wheel 3 and the rear wheel 12, no current flows through the cross pipe 30 even if the cathode terminal 21b comes into contact when the battery 21 is rotated. Therefore, an electric shock at the time of battery replacement can be prevented.

  After the vertical orientation, the battery 21 is pushed forward until the lower end of the battery 21 comes into contact with the inclined portion 23b, and the battery 21 is positioned toward the front wall 23a of the case body 23. Further, the battery 21 is pushed to the left until the left side surface of the battery 21 hits the damper members 33 a and 33 b and is brought close to the left wall 23 d of the case body 23. Thus, the battery 21 is arranged at the mounting position by being brought close to the front wall 23a and the left wall 23d of the case body 23.

  After being arranged at the mounting position, the fixed cover 34 is inserted from the battery entrance 32. If the fixed cover 34 is mounted in the battery housing space 25, the front end portion and the rear end portion of the right support portion 35 are hooked on the cross pipe 30 and the rear bracket 29. Therefore, the fixed cover 34 is inclined obliquely so as to lower the front side of the right support part 35 from the posture at the time of mounting, and is hidden under the cross pipe 30 and is pushed forward along the right side surface of the battery 21 as it is. In this way, the battery is inserted from the battery inlet / outlet 32. When the rear support part 36 of the fixed cover 34 enters the battery housing space 25 by being pushed in, the rear support part 36 side of the fixed cover 34 is lowered and the case side mounting plate 35 a is placed on the bottom surface 23 e of the case main body 23.

  After being placed, the fixed cover 34 is moved so that the protruding portion 35 c of the right support portion 35 and the protruding portion 36 a of the rear support portion 36 are brought into contact with and supported by the battery 21. After abutting and supporting, the battery 21 is pressed against the damper members 33 a to 33 c through the fixed cover 34. In this state, the case side mounting plate 35 a is fixed to the bottom surface 23 e of the case main body 23, and the frame side mounting portion 38 is fixed to the seat rail 14. The battery 21 is mounted on the battery mounting structure 1 by attaching the fixed cover 34 in this manner. The battery 21 mounted in this way is firmly supported from front to back and left and right so that it does not move due to vibration or the like during traveling, and is regulated so as not to jump out from above due to vibration or the like. The mounted battery 21 can be removed from the battery mounting structure 1 by performing a procedure reverse to the procedure of the mounting method described above.

  As described above, in the battery mounting structure 1, the battery 21 is inserted horizontally into the battery inlet / outlet 32, and the battery 21 is directly lowered and lowered onto the bottom surface 23 e of the case body 23, and the battery 21 is rotated to be in the vertical direction. Thus, the battery 21 can be mounted. Therefore, the operator does not need to push or move the battery case 22 containing the battery 21 when inserting it into the battery inlet / outlet port 32 as in the prior art, and the battery 21 can be easily mounted. In addition, since the battery 21 overlaps the cross pipe 30 in plan view, it is difficult to remove the battery 21 and theft can be prevented. That is, since it is easy to insert the battery 21 into the battery housing space 25, the battery 21 cannot be pulled out immediately, so that both ease of attachment and prevention of the theft of the battery 21 can be achieved. On the other hand, since the fixed cover 34 is made of a synthetic resin, its weight itself is smaller than that of the battery 21 and can be easily attached even if it is inserted at an angle as described above.

[Other embodiments]
Although the dual-purpose type motorcycle has been described in the present embodiment, it may be an off-road type or on-road type motorcycle, or may be an automatic four-wheeled vehicle such as an ATV (All Terrain Vehicle). Further, a case such as the battery case 22 is not necessary, and the battery accommodating space 25 may be formed by the frame 7, and the battery 21 may be accommodated in the battery accommodating space 25 and fixed to the frame 7. . Moreover, in this embodiment, although no components are interposed between the battery 21 and the silencer 19, a heat insulating member such as a heat insulating wall may be interposed. Thereby, the temperature rise of the battery 21 can be suppressed, and the occurrence of defects due to the temperature can be further suppressed.

  The present invention can be applied to a vehicle including a battery mounting structure for mounting a battery on a vehicle body.
