Description

[Detailed description of the invention] This invention relates to a battery attachment device for a motorcycle.
It is mainly suitable for motorcycles.

Conventionally, when attaching a battery to the body of a two-wheeled vehicle, a box-shaped battery case is fixed to the body frame, and the battery is housed within the case. However, in the conventional configuration described above, a box-shaped member with an internal capacity comparable to the size of the battery must be used to store the battery, which makes the battery case bulky, increases storage space, and makes parts management troublesome. Not only that, but it is also a factor that prevents weight reduction of car bodies. As a prior art
There are No.-32367 and Utility Model No. 53-67245.

In view of the above-mentioned problems, the present invention uses an air cleaner to support a part of the battery, thereby eliminating the need for the conventionally required large box-shaped battery case, reducing the weight of the vehicle body, and making it possible to reduce the weight of the vehicle body. The purpose is to make it possible to downsize dedicated components, facilitate component management, and reduce costs. Next, the present invention will be explained based on the drawings.

FIG. 1 is a vertical left side view of a battery attachment device according to the present invention adopted in a motorcycle. 1st
In the figure, the rear descending frame pipe 1 is the right one of two pipes installed in parallel on both the left and right sides of the vehicle body, and there is a space between the right pipe 1 and the parallel left pipe (not shown). Two horizontal horizontal cross pipes 2 and 3 are constructed by welding. A bracket 4 projecting vertically downward is welded to the upper cross pipe 2, and a grommet 5 made of a rubber-like elastic body is fitted into a hole provided in the bracket 4. Grommet 5
The air cleaner 6 has a case made of resin.
A fitting protrusion 7 protruding from the front end is press-fitted from the rear to be locked. A U-shaped recess 8 that opens rearward when viewed from above is formed at the rear of the air cleaner 6, and the upper end of a bracket 9 fixed to the rear end is attached to a bolt 11 on the lower surface of a horizontal sheet metal cross member 10. It is twisted and tightened. Both left and right ends of the cross member 10 are welded to two parallel frame pipes (not shown) that extend substantially horizontally in the front-rear direction. That is, air cleaner 6
is fixed to the frame pipe 1 by having its front end locked to a bracket 4 and its rear end fixed to a cross member 10. Here, 12 is an air suction duct, and 13 is an inlet duct that communicates with a carburetor (not shown) of the engine. Note that in FIG. 1, the internal structure of the air cleaner 6 is omitted.

As shown in FIG. 2, a bracket 14 having a substantially U-shaped cross section is welded to the lower cross pipe 3, and a shock absorber 15 is attached to the bracket 14.
Bolt 17 whose upper end boss 16 is parallel to pipe 3
It is rotatably supported via. The shock absorber 15 is a member that restricts the rotation of a rear wheel swing arm (not shown) of a motorcycle and absorbs vibrations, and in this case, a single shock absorber system is adopted. Furthermore, a bracket 19 welded to the lower surface of a battery receiving plate 18 made of sheet metal is fitted from the outside to the bracket 14, and is fastened to the bracket 14 by the bolts 17 mentioned above.

As is clear from FIG. 1, the battery receiving plate 18 is a substantially L-shaped member when viewed from the side.
A damper 20 made of several rubber-like elastic bodies is fitted into the damper 8a and the vertical plate 18b. As shown in FIG. 3, the damper 20 has a fitting projection 22 that projects at right angles to the center of a disc-shaped portion 21.
The protrusion 22 fits into the hole 23 provided in the plate 18 from the inside of the receiving plate 18, and the annular step 24 formed in the middle of the protrusion 22 is hooked to the peripheral edge of the hole 23, so that the protrusion 22 can be pulled out. A stop has been applied. As shown in FIG. 1, a flange portion 18c bent at right angles is formed at the upper end of the vertical plate 18b, and the flange portion 18c is placed on the cross member 10 and fastened with vertical bolts 25. ing.
That is, the battery receiving plate 18 is fixed to the frame pipe 1 by having its lower end fixed to the bracket 14 and its upper end fixed to the cross member 10. As a result, inside the battery receiving plate 18, the bottom plate 18a becomes the bottom surface, and the vertical plate 18b
and the 3 side walls of the recess 8 of the air cleaner 6 are 4, respectively.
A substantially quadrangular prism-shaped case-like portion 26 is formed on one side surface and is open only at the upper end, and a quadrangular prism-shaped battery 27 is fitted into this case-like portion 26 from above.

A rectangular dish-shaped tool case 28 extending horizontally back and forth is arranged at the upper end of the case-like portion 26 . The tool case 28 is made of resin and integrally has a fitting protrusion 29 at the front end, and the protrusion 29 is press-fitted and locked into a grommet 31 made of a rubber-like elastic body that fits into a hole in a bracket 30. There is. The bracket 30 is fixed to the frame pipe 1 by welding its lower end to the cross pipe 2. As is clear from FIG. 4, the tool case 28 extends back and forth around the center line O-O of the vehicle body, and the rear half of the case 28 covers the upper center portion of the case-like portion 26, and The tongue portion 32 formed at the rear end is connected to the screw 33.
It is fixed to the upper center surface of the cross member 10 by. The bottom surface of the tool case 28 prevents the battery 27 from flying upward. Furthermore, as shown in FIG.
4th prize is accepted. Although not shown in the figure, the upper part of the tool case 28 is covered by a hinged seat that can be opened and closed, so that the repair tools 34 and the like stored in the case 28 will not fall out while the vehicle is running.
In addition, in Figure 1, the battery 27 and tool case 28 are shown.
Although there is a slight gap formed between the
By changing the thickness of the damper 20 fixed to 8a,
The tool case 28 may be brought into pressure contact with the upper end surface of the battery 27. Further, a rubber-like elastic damper may be interposed between the battery 27 and the case 28.

To remove the battery 27, remove the screw 33, slightly lift the rear end of the tool case 28, pull it backwards, remove the fitting protrusion 29 from the grommet 31, remove the tool case 28, and then remove the tool case 28. The battery 27 is pulled up above the portion 26. When storing the battery 27, the reverse operation may be performed.

As explained above, the present invention covers three of the four sides of the rectangular prism battery 27 with the recess 8 in the U-shape of the planar U-shaped resin air cleaner 6 fixed to the vehicle body frame, and covers the remaining one side. A damper 2 made of a rubber-like elastic body is connected to a battery receiving plate 18 made of sheet metal and having a substantially L-shaped cross section, which is fixed to the vehicle body frame.
Since the top surface is covered with a resin tool case 28 which is detachably fixed to the vehicle body frame, the following effects can be obtained. That is, according to the present invention, three of the four sides of the rectangular column battery 27 are covered with the U-shaped recess 8 of the air cleaner 6 fixed to the vehicle body frame (frame pipe 1), and the remaining one side and the bottom are covered with the vehicle body. Since the battery receiving plate 18, which is fixed to the frame and has an approximately L-shaped cross section, covers the battery, the large box-shaped battery case that was conventionally required is no longer required. Only the plate 18 is required;
This has the advantage of reducing the weight of the vehicle body. Furthermore, the battery receiving plate 18 is smaller and simpler in shape than a conventional box-shaped battery case, which has the advantage of facilitating parts management and reducing costs by reducing storage space.

Furthermore, according to the present invention, the heavy battery 27 is supported by the bottom plate 18a of the battery receiving plate 18 made of sheet metal via the damper 20 made of a rubber-like elastic body.
The load of the battery 27 does not act on the air cleaner 6 at all, so there is no risk of the air cleaner 6 being deformed. In addition, since the vertical plate 18b of the battery receiving plate 18 covers the opening surface of the recess 8, the battery 27 is accommodated in the space inside the bottomed recess 8, and there is no risk of it falling off due to vibrations during driving. Does not occur.
In addition, since the top surface of the battery 27 is covered with a resin tool case 28 that is detachably fixed to the vehicle body frame, there is no risk of the battery 27 flying upward even if strong vertical vibration occurs while driving. Since the tool case 28 is not just a flat lid, it has high rigidity in relation to its weight, and can conveniently store repair tools 34 and the like. Furthermore, in the present invention, the air cleaner 6 that covers the three sides of the battery 27 and the tool case 28 that covers the top surface are made of resin, so that the impact when the battery 27 comes into contact with the wall of the air cleaner 6 or the tool case 28 itself is absorbed. , there is an advantage that the required number of dampers 20 made of rubber-like elastic material is small. In order to facilitate the removal of the battery 27, a rubber band 35 may be wrapped around the battery 27 in advance as shown in FIG. For example, the rubber band 35 has a width of 20 mm and a thickness of 2~
It is about 2.5mm. Two or more rubber bands 35 may be provided in parallel or orthogonal positions. In this case, the battery 27 can be easily taken out by grasping the upper end of the band 35. Further, in order to make it possible to easily take out the battery 27, the following configuration can be adopted.

In FIG. 6, a pull-out wire device 37 is arranged along the inner wall surface of the case-like portion 26. As shown in FIG. As shown in FIG. 7, the wire device 37 is mainly formed by tying a metal ring 39 to the middle part of a wire body 38, which is an inner wire coated with resin, and crimping rings at both ends of the wire body 38. Annular portions 41, 41 formed by caulking with 40, 40
have. As shown in FIG. 6, the annular portion 41 has two bolts 42 spaced apart from each other in the left and right direction (perpendicular to the paper) on the upper end surface of the air cleaner 6.
(only one is shown).
That is, as shown in FIG. 8, an upward female screw member 43 is embedded in the upper end of the air cleaner 6 in advance, and a bolt 42 passing through an annular portion 41 and a washer 44 is screwed into the female screw member 43. An annular portion 41 is fixed to the upper end surface of the air cleaner 6. As shown in FIG. 6, the battery 27 is placed on the wire main body 38 in the stored state. At this time, the wire main body 38 is bifurcated with the ring 39 as a fulcrum, and They are arranged in a posture (a posture as shown in FIG. 7) in which the intervals gradually widen as they move along the annular ring 39 toward the annular portion 41.

Therefore, when pulling out the battery 27 from inside the case-like part 26, by pulling up the ring 39, the battery 27 is lifted by the wire main body 38 as shown by the imaginary line 27', and the battery 27 can be easily taken out. It will be done. On the other hand, when storing the battery 27, as shown in FIG. 9, if the ring 39 is placed between the tongue 32 of the tool case 28 and the cross member 10 and tightened together with the screw 33, the ring 39 can be secured while the car is running. Problems such as falling into the case-like portion 26 (FIG. 6) do not occur. Moreover, the screw 33 is a member that must be removed when removing the battery 27 (FIG. 6), so there is no need to take time to attach or detach the ring 39.

Note that the rubber band 35 in FIG. 5 and the wire body 38 coated with resin in FIG. 7 have a shock-absorbing effect, so if these are used, the damper 20 in FIG. 1 may be omitted.
