By the way, when the battery carrier is arranged close to the front tire of the vehicle due to layout restrictions or the like, it is conceivable that the spray from the front tire will fly to the battery carrier.

However, the battery carrier does not take into account the spray from the front tires. Specifically, the lower part of the battery carrier on the chassis frame side is open so as to allow the battery cable to pass through. Further, the cover covers the battery with a slight gap, and there is a gap that opens downward between the cover and the outer circumference of the battery.

Therefore, if a large amount of water splashes from the front tire toward the battery carrier, the water spray may reach the top surface of the battery. In this case, it is conceivable that the battery terminal and other metal parts are electrically connected via water, and a leak current may be generated.

Especially in trucks and the like, when 12V and 24V are taken out from two batteries, an equalizer may be connected to these batteries in order to prevent one battery from being depleted. In this case, a large number of metal parts such as terminals are arranged on the upper surface of the battery, and a leak current is likely to occur.

Therefore, the present invention has been conceived in view of such circumstances, and an object of the present invention is to provide a water-impervious structure for a battery capable of preventing or suppressing splashing water from below from reaching the battery terminal on the upper surface of the battery.

Further, the battery carrier 3 includes a bracket 10 for attaching the front side wall plate member 6a and the rear side wall plate member 6b to one side of the chassis frame 4.

As shown in FIGS. 5 and 6, the bottom plate member 7 mounts the battery 2 and is formed to have a smaller dimension in the vehicle width direction than the front side wall plate member 6a and the rear side wall plate member 6b. Further, the bottom plate member 7 is hung between the wall plate members 6a and 6b on the outer side in the vehicle width direction. As a result, a release portion 12 for vertically inserting the battery cable 11a is formed between the wall plate members 6a and 6b inside the bottom plate member 7 in the vehicle width direction.

As shown in FIGS. 2 and 4, two batteries 2 are placed side by side on the bottom plate member 7 in the front-rear direction. Further, the equalizer 14 is provided on the front side wall plate member 6a and the rear side wall plate member 6b on the chassis frame 4 side via the mounting bracket 13. The equalizer 14 is for preventing one battery 2 from being depleted when 12V and 24V are selectively taken out from two 12V batteries 2, and is connected to each battery 2.

As shown in FIGS. 2 and 5, the battery impermeable structure according to the present embodiment is provided on the above-mentioned battery carrier 3 and the battery carrier 3 via a support member 15, and the upper surface of the battery 2 is spaced apart from each other. It is provided with a battery cover 16 for covering the battery, a release portion 12 described above, and a splash guard 17 arranged on the release portion 12 for receiving splashes of water flying from below.

The battery cover 16 includes a top plate portion 16a that covers the upper surfaces of the two batteries 2 with sufficient dimensions in the front-rear and left-right directions, an outer peripheral flange portion 16b formed extending downward from the outer periphery of the top plate portion 16a, and an outer peripheral flange portion. It is provided with a receiving portion 16c which is formed so as to extend outward in the horizontal direction from 16b and receives a support member 15 which will be described later. A battery cable 11b for connecting the negative pole (not shown) of the battery 2 and the chassis frame 4 is passed through the gap formed between the outer peripheral flange portion 16b and the battery 2. A slit 18 is formed in the receiving portion 16c for inserting the J bolt 8 described later. One end of the slit 18 is released.

The support member 15 fixes and supports the battery 2 to the battery carrier 3, and supports the battery cover 16 in a state of being floated from the battery 2.

As shown in FIGS. 3 and 4, the support member 15 has a plurality of spacers 19 and 20 mounted side by side on the two batteries 2 in the front-rear direction, and has a longer length in the front-rear direction than the two batteries 2. A pressing member 21 that is formed and placed so as to be hung on the spacers 19 and 20, and J that is inserted into the pressing member 21 and the receiving portion 16c of the battery cover 16 and is fastened to the retaining hole 9 of the battery carrier 3. It includes a bolt 8, a battery nut 22 that is screwed into the J bolt 8 and presses the pressing member 21 downward, and a cover nut 23 that is screwed into the J bolt 8 and presses the battery cover 16 downward. Spacers 19 and 20 are made of elastic resin. The pressing member 21 is composed of a metal rod extending in the front-rear direction. At both ends of the pressing member 21, holes 21a for inserting the J bolt 8 are formed by bending a metal rod in an annular shape.

As shown in FIGS. 5, 6 and 7, the splash guard 17 includes a battery-side upright portion 24 extending upward along the side surface of the battery 2 on the chassis frame 4 side, and a chassis frame from the upper end of the battery-side upright portion 24. A horizontal portion 25 extending to the 4 side and a chassis frame side upright portion 26 extending upward from the tip of the horizontal portion 25 on the chassis frame 4 side are provided.

The battery-side upright portion 24 is set so as to cover the lower side surface of the battery 2 with a minute interval. The horizontal portion 25 is formed so that the position on the inner side in the vehicle width direction (chassis frame 4 side) is the same as the inner end in the vehicle width direction of the front side wall plate member 6a and the rear side wall plate member 6b. As a result, the inner surface of the rear side wall plate member 6b can be hidden from the front tire 5a in the immediate front, and the spray of water flying from the front tire 5a can be prevented or suppressed from hitting the inner surface of the rear side wall plate member 6b.

The chassis frame side upright portion 26 extends upward along the inner ends of the front side wall plate member 6a and the rear side wall plate member 6b in the vehicle width direction. As a result, the battery 2 can be hidden from the front tire 5b on the opposite side (right side) of the battery 2, and the spray flying from the front tire 5b on the opposite side can be prevented or suppressed from directly hitting the battery 2. ..

Further, at both front and rear ends of the battery-side upright portion 24, attachment portions 27 for attaching the splash guard 17 to the front side wall plate member 6a and the rear side wall plate member 6b extend inward (to the right) in the vehicle width direction and are integrated. It is provided in. A hole 29 for inserting the bolt 28 is formed in the mounting portion 27. The mounting portion 27 is located inward in the vehicle width direction from the battery-side standing portion 24 and below the horizontal portion 25. Therefore, when the splash guard 17 is attached to the existing battery carrier 3 with the bolt 28 and the nut (not shown), both the bolt 28 and the nut are exposed to the outside of the battery carrier 3. Therefore, the bolt 28 and the nut can be easily supported or rotated by a tool. As a result, the splash guard 17 can be easily attached to the existing battery carrier 3.

Further, the splash guard 17 is formed with an opening 30 for inserting the battery cable 11a connected to the positive pole (not shown) of the battery 2. The opening 30 is formed by cutting out the chassis frame side upright portion 26 downward from the upper end, and also by notching the horizontal portion 25 from the chassis frame side upright portion 26 to the battery 2 side. The opening 30 is formed in a size that does not interfere with the maintenance of the battery cable 11a, specifically, a size that allows all the fingers of one hand of the operator to be inserted.

The battery-side upright portion 24, the horizontal portion 25, the chassis frame-side upright portion 26, and the mounting portion 27 are formed by bending one metal plate. The splash guard 17 is not limited to metal. For example, the splash guard 17 may be made of another material such as resin.

Next, the operation of this embodiment will be described.

When the vehicle 1 travels in the rain, the battery cover 16 repels the rain that falls on the battery 2. Therefore, the rainfall does not reach the upper surface of the battery 2 directly.

Further, when the spray from the front tire 5a in the immediate front flies diagonally upward toward the battery carrier 3, the spray reaching the release portion 12 hits the splash guard 17 and is repelled. Therefore, it is possible to prevent the spray from hitting the inner surface of the rear side wall plate member 6b.

Conventionally, the release portion 12 has nothing to block the spray of water from the front tire 5a. Therefore, the spray of water that has passed through the release portion 12 may hit the inner surface of the rear side wall plate member 6b and be bounced off, and may reach the upper surface of the battery 2 through the gap between the battery 2 and the outer peripheral flange portion 16b.

However, in the battery impermeable structure according to the present embodiment, the splash guard 17 blocks the spray from the front tire 5a. Therefore, the amount of water spray that hits the inner surface of the rear side wall plate member 6b is zero or very small. Thereby, it is possible to prevent or suppress the spray from reaching the upper surface of the battery 2.

Further, the spray of water splashed from the front tire 5b on the opposite side of the battery 2 is blocked by the upright portion 26 on the chassis frame side. Therefore, it is possible to prevent or suppress the spray of water directly on the battery 2. Then, it is possible to prevent or suppress the splash of water from rising along the battery 2 and reaching the gap between the battery 2 and the outer peripheral flange portion 16b.

As described above, the battery impermeable structure according to the present embodiment is provided on the battery carrier 3 provided in the chassis frame 4 and the battery carrier 3 via the support member 15 and covers the upper surface of the battery 2 at intervals. A battery cover 16, a release portion 12 formed on the bottom of the battery carrier 3 on the chassis frame 4 side, and a splash guard 17 arranged on the release portion 12 for receiving splashes flying from below are provided. Therefore, it is possible to prevent or suppress the spray from the front tires 5a and 5b from passing through the release portion 12, and prevent or suppress the spray from reaching the battery terminal (not shown) on the upper surface of the battery 2.

Further, the splash guard 17 is formed separately from the battery carrier 3 and is provided so as to span between the front and rear wall plate members 6a and 6b. Therefore, even if the existing battery carrier 3 is used, the splash guard 17 can be retrofitted to the battery carrier 3, and the spray from the front tires 5a and 5b can be easily dealt with. Then, it can be attached to the battery carrier 3 with a simple structure. Since the battery carrier 3 is used as a common component among a plurality of vehicle types, it can be inexpensively used for a large number of existing vehicles 1.

Further, the splash guard 17 includes a battery-side upright portion 24 extending upward along the side surface of the battery 2 on the chassis frame 4 side, a horizontal portion 25 extending from the upper end of the battery-side upright portion 24 to the chassis frame 4 side, and a horizontal portion. The chassis frame side standing portion 26 extending upward from the tip of the chassis frame 4 side of the 25 is provided. The battery-side upright portion 24 can block the spray of water from the front tire 5a in front of the battery toward the battery 2. The horizontal portion 25 can block the spray of water from the front tire 5a in the immediate front toward the rear side wall plate member 6b. The chassis frame side upright portion 26 can block the spray of water that is blown from the front tire 5b on the opposite side of the battery 2 and heads toward the battery 2. Then, the battery-side upright portion 24, the horizontal portion 25, and the chassis frame-side upright portion 26 can block the spray of water toward the gap between the battery 2 and the outer peripheral flange portion 16b by various routes, and can be applied to the upper surface of the battery 2. It is possible to prevent or suppress the arrival of splashes.

Further, the opening 30 of the splash guard 17 is formed by cutting out the chassis frame side standing portion 26 downward from the upper end and cutting out the horizontal portion 25 from the chassis frame side standing portion 26 to the battery 2 side. .. Therefore, when the splash guard 17 is attached to the existing battery carrier 3, the splash guard 17 can be attached without removing the battery cable 11a already inserted in the release portion 12, and the splash guard 17 can be attached to the existing battery carrier 3. Can be easily installed.

Further, the position of the battery cable 11a in the release portion 12 may differ depending on the vehicle type. However, by preparing in advance a plurality of types of splash guards 17 in which the positions and shapes of the openings 30 are changed so as to correspond to these vehicle types, it is possible to easily correspond to various vehicle types.

Although the embodiments of the present invention have been described in detail above, the present invention can also have other embodiments as follows.

(1) As shown in FIG. 8, the horizontal portion 32 of the splash guard 31 may extend beyond the wall plate members 6a and 6b toward the chassis frame 4. In this case, the horizontal portion 32 may be extended to a position covering the bottom surface of the equalizer 14. Further, the chassis frame side upright portion 33 of the splash guard 31 may be extended to a position that partially covers the surface of the equalizer 14 on the chassis frame 4 side. It is possible to prevent water from entering the battery 2 side through the gap between the equalizer 14 and the chassis frame side upright portion 33. Then, the possibility that the spray reaches the upper surface of the battery 2 can be further reduced.

(2) Although the splash guard 17 is attached to the front and rear wall plate members 6a and 6b, it may be attached to the bottom plate member 7, or may be attached to the bracket 10 or the attachment bracket 13. Further, the splash guard 17 may be attached to a member other than the battery carrier 3, for example, a chassis frame 4.

The configurations of each of the above embodiments can be combined partially or wholly, unless otherwise inconsistent. The embodiment of the present invention is not limited to the above-described embodiment, and all modifications, applications, and equivalents included in the idea of the present invention defined by the claims are included in the present invention. Therefore, the present invention should not be construed in a limited manner and can be applied to any other technique belonging within the scope of the idea of the present invention.
