Description

  The present invention mainly relates to a battery box for storing a battery mounted on a vehicle such as a truck.

  In a truck for carrying luggage, a loading platform is supported on a frame extending in the front-rear direction on the left and right sides of the vehicle, and a battery box for storing a battery is disposed on the outer side in the vehicle width direction of one of the frames. There is something.

  When the battery is mounted in a state of being exposed to the outside as described above, the battery is easily contaminated by muddy water (see the arrow in FIG. 1) or dust during traveling. Therefore, in order to prevent dirt due to muddy water and dust, in many cases, a configuration in which a battery is placed on a battery holder and the battery is covered with a cover is employed as a configuration of the battery box.

  The cover of the battery box is required to be securely attached to the battery holder using screws, clips or the like so as not to be removed due to vibration or the like during traveling. On the other hand, since it is necessary to check the battery, replenish electrolyte, etc., it is desirable that the cover can be easily attached to and detached from the battery holder.

  For example, Patent Document 1 discloses a battery storage device for a truck in which a cover that covers the outside of the battery can be displaced to a storage position and an open position that opens the outside of the battery. That is, in the battery storage device disclosed in Patent Document 1, a through groove is formed in the cover, and a locking member that is rotatably attached to a support base (battery holder) is inserted into the through groove. The member is locked in the locking portion at the first rotation angle position, and can be relatively displaced along the through groove at the second rotation angle position.

JP-A-5-58170

  However, in the battery storage device disclosed in Patent Document 1, it is necessary to insert a locking member into the through groove, and the configuration becomes complicated. In particular, the locking member is configured to be relatively displaced along the through-groove. However, as described above, it is easily contaminated by muddy water or dust, so that mud or dust is caught between the locking member and the through-groove. As a result, smooth movement may be hindered.

  Also, considering work such as battery inspection and electrolyte replenishment, it is possible to improve the workability by completely removing the cover from the battery holder, but when attaching and detaching the cover to the battery holder, There has been no proposal to easily position the cover with respect to the battery holder or to easily attach or remove screws or clips. In particular, when it is dirty with muddy water or dust, the positioning of the cover and the attaching / detaching operations of screws, clips, etc. become even more difficult.

  The present invention has been made in view of the above points, and an object of the present invention is to make the cover easily detachable from the battery holder.

  The battery box according to the present invention includes a battery holder having a bottom surface and a pair of side surfaces on which the battery is placed, and a cover having a pair of side surfaces that covers the battery placed on the battery holder and overlaps the side surfaces of the battery holder. And an inclined receiving surface provided on a side surface of the battery holder, and an inclined surface provided on a side surface of the cover, wherein the inclined surface is the receiving surface in a state where the cover is attached to the battery holder. It is characterized in that it is configured to overlap.

  According to the present invention, when the cover is attached to the battery holder, the cover-side inclined surface may be overlapped with the battery holder-side inclined receiving surface, so that the cover can be easily positioned with respect to the battery holder. it can. Moreover, since connection members, such as a screw and a clip, should just be attached or removed with respect to the inclined surface of a cover side, the workability | operativity can be improved. Thus, the cover can be easily attached to and detached from the battery holder.

These support portions 29 have a groove shape in cross section, and a protrusion 29a protruding downward is formed on the bottom surface. When the cover 3 is attached to the battery holder 1, the bottom surfaces of these support portions 29 are just in contact with the bottom surface 4 of the battery holder 1 (they are just placed on the bottom surface 4). Directional positioning. Further, the protrusion 29 a is inserted into an engagement hole 30 formed in the bottom surface 4 of the battery holder 1, and the cover 3 is positioned in the horizontal direction with respect to the battery holder 1.

  The side surface 26 overlaps a part of the side surface 5 of the battery holder 1, specifically, a portion of the side surface 5 of the battery box 1 that is on the side opposite to the vehicle from the convex portion 12. An inclined surface 26 a is integrally formed on the side surface 26 at a position corresponding to the receiving surface 12 a of the battery box 1 so as to be positioned on the inner side with a step with respect to the side surface 26. The inclined surface 26a is inclined on both the outer surface and the inner surface thereof, and is inclined so that the surface faces the battery holder 1 side. A hole 32 for inserting the clip 31 is formed in the inclined surface 26a.

  Similarly, the side surface 27 overlaps a part of the side surface 6 of the battery holder 1, specifically, a portion of the side surface 6 of the battery box 1 on the side opposite to the vehicle from the convex portion 14. An inclined surface 27 a is integrally formed on the side surface 26 at a position corresponding to the receiving surface 14 a of the battery box 1 so as to be located on the inner side with a step with respect to the side surface 27. The inclined surface 27a is inclined on both the outer surface and the inner surface thereof, and is inclined so that the surface faces the battery holder 1 side.

As shown in FIG. 5A, the inclined surfaces 26a and 27a of the cover 3 are compared with the width A between the outer ends of the bent portions 17 and 18 formed on the both side surfaces 5 and 6 of the battery holder 1. The maximum inner surface width B _max is large (B _max > A), and the minimum inner surface width B _min is small (B _min <A).

  When storing the battery B in the battery box described above, the battery B is placed on the battery holder 1 and the band 2 is attached to fix the battery B (state shown in FIG. 2).

Thereafter, the cover 3 is attached to the battery holder 1. As described above, the cover 3 is compared with the width A between the outer ends of the bent portions 17 and 18 formed on the side surfaces 5 and 6 of the battery holder 1. 3 has a large maximum width B _max (B _max > A), and when the cover 3 is brought close to the battery holder 1 (arrow X in FIG. 5A), the bent portions 17 and 18 are outside. The end portions are in contact with the inner surfaces of the inclined surfaces 26a and 27a, respectively.

  When the cover 3 is pushed into the battery holder 1 side with the outer ends of the bent portions 17 and 18 being in contact with the inner surfaces of the inclined surfaces 26a and 27a, the cover 3 is guided to the outer ends of the bent portions 17 and 18 respectively. In addition to being centered, the two inclined surfaces 26a and 27a of the cover 3 are elastically deformed so as to be pushed and spread by the outer ends of the bent portions 17 and 18. As described above, the cover 3 can be temporarily held in a state where both the inclined surfaces 26a and 27a of the cover 3 are elastically deformed so as to be pushed by the outer end portions of the bent portions 17 and 18 and expand.

Then, when the cover 3 is pushed into the battery holder 1 as it is, the minimum width portions of the inner surfaces of the inclined surfaces 26a, 27a get over the outer ends of the bent portions 17, 18 due to elastic deformation of the inclined surfaces 26a, 27a. After getting over, the inclined surfaces 26a and 27a are elastically restored and the interval is restored. In this state, since the minimum width _{Bmin of the} inner surface is smaller than the width A between the outer end portions of the bent portions 17 and 18, the step is caught with the bent portions 17 and 18, and the cover 3 is temporarily held. Is also possible. After getting over, the inclined surfaces 26a and 27a overlap the receiving surfaces 12a and 14a, respectively, as shown in FIG. 5 (b).

  Further, as described above, the bottom surface of the support portion 29 of the cover 3 is just placed on the bottom surface 4 of the battery holder 1, and the protrusion 29 a is inserted into the engagement hole 30 formed in the bottom surface 4 of the battery holder 1. The Thereby, it is possible to reliably prevent the cover 3 from falling off and to restrict the movement of the cover 3 in the front-rear and left-right directions.

  When the cover 3 covers the battery B as described above, the clips 31 and 33 are inserted into the overlapping receiving surfaces 12a and 14a and the inclined surfaces 26a and 27a, respectively. Fix to 1.

  Conversely, when removing the cover 3 from the battery holder 1, after removing the clips 31 and 33, the cover 3 may be pulled away from the battery holder 1 while expanding the inclined surfaces 26 a and 27 a of the cover 3.

  In the battery box described above, when the cover 3 is attached to the battery holder 1, the inclined surfaces 26a and 27a on the cover 3 side may be overlapped with the inclined receiving surfaces 12a and 14a on the battery holder 1 side. Positioning of the cover 3 with respect to the battery holder 1 can be easily performed.

  Moreover, since connecting members, such as a screw and a clip, should just be attached or removed with respect to the inclined surfaces 26a and 27a which orient | assign a surface to an operator side, a connecting member is just beside (perpendicular to side surfaces 26 and 27) Compared with attaching and detaching, the workability can be remarkably improved.

  Further, when the cover 3 is attached to the battery holder 1, the clips 31 and 33 are positioned on the back side (vehicle side) of the bent portions 17 and 18, and the inclined surfaces 26 a and 27 a for attaching the clips 31 and 33 are the side surfaces 26, 27, the clips 31 and 33 are less likely to appear on the appearance, and the appearance quality can be improved.
