BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle battery tray applied to an automobile.

0002

2. Description of the Related Art Depending on the type of automobile, a battery may be placed near the engine. If the battery is placed near the engine in this way, the heat dissipated from the engine will have a negative effect on the battery.
A heat shield is provided. Also, if the battery is located close to the engine, there is a high possibility that the battery wiring cable (wire harness) will come into contact with the engine. Avoid contact with hot parts of the equipment.

A conventional battery tray is such that a battery 2 is placed on a tray plate 1, as shown in FIG. This battery tray is used when the battery is installed relatively far from the engine. Next, the battery tray shown in FIG.
A heat shielding plate 3 is provided around the periphery of the plate plate 1 so as to surround the battery 2 placed on the plate.

FIG. 11 shows an L-shaped cable 5 connected to the battery terminal 4, which is forcibly guided downward to prevent the cable 5 from interfering with other equipment. A bent guide hardware 6 is provided. This battery tray is not provided with a heat shield.

Next, in Japanese Patent Application Laid-Open No. 61-135841, a through hole is provided in a flange provided in a case for storing a battery, and a cable is inserted through this through hole, similar to the one in FIG. 11. A device in which the cable is guided downward has been disclosed in Japanese Utility Model Application Publication No. 61-61755.
This publication discloses a case in which the upper edge of a storage box for a lead-acid battery is cut out to guide a cable, and Japanese Utility Model Application Publication No. 56-49631 discloses a case in which a reservoir tank is inserted into a battery compartment. It has been disclosed that a reservoir tank is manufactured to match the shape of a battery so that it also serves as a heat shielding plate.

[0006]

[Problem to be solved by the invention] In the above conventional example,
Both the system shown in FIG. 10 and the system in which the reservoir tank also serves as a heat shield plate have the following problems. In other words, in these conventional examples, there is nothing to guide the battery cables, so the assembly worker can route the cables arbitrarily within the engine room. . For example, when the battery 2 is installed near the engine 9 in the engine room 11 as shown in FIGS. 6 to 8, the operator arbitrarily routes the cable 12.

In the case shown in FIG. 6, there is no problem because the cable 12 is routed so that it does not come into contact with the exhaust manifold 10, but as shown in FIG. If the cable 12 is routed so as to come into contact with the exhaust manifold, there is a problem that the cable 12 will be damaged by the heat of the exhaust manifold, causing electrical trouble. Also, Figure 8
As shown in FIG.
If the battery fluid is routed through the top or between the cables, the fluid port stopper 13 may become loose for some reason, and the battery fluid that leaks from there may adhere to the cable 12, corroding the cable and causing electrical trouble. There is a problem with becoming. These problems occur due to the operator's carelessness or skill level, and pose a problem in terms of workability.

Next, as shown in FIG. 11, the cable is guided downward through a hole drilled in the flange of the battery case, which has the following problems. First, Figure 11
When assembling the battery 2, the cable 5 is inserted into the guide hole made in the flange 7 of the guide hardware 6, and then the end of the cable 5 is attached to the battery terminal 4. The end portion and the guide hardware 6 must be fastened together to the battery terminal 4 with a fixed hardware 8. On the other hand, the cable is guided downward through a hole in the flange of the battery case.
When assembling the battery, it is necessary to insert the cable through the hole.

[0009] If the work of inserting the cable through the hole is involved during the assembly work, the assembly procedure is restricted, and it takes time to insert the cable through the hole, resulting in poor assembly work efficiency. There is a problem. This is particularly a problem for products that are mass-produced, such as automobiles, because reducing the time required for one assembly by a few seconds can greatly affect productivity.

Furthermore, in the case shown in FIG. 11, since the guide hardware 6 is provided separately, the number of assembly parts increases, and if a heat shield plate is provided, its installation may become troublesome. There is a problem that productivity decreases due to

[0011] Next, the upper edge of the lead-acid battery storage box is cut out to guide the cable, and this is placed on the tray when installing the lead-acid battery. There is no disclosure regarding a battery tray.

[0012] The present invention protects the battery from engine heat by integrating a plate plate, a heat shield plate, and a cable guiding clamp into a tray, and also controls the cable routing. A vehicle battery that prevents heat damage and is easy to assemble.
It provides a tray.

[0013]

[Means for Solving the Problems] The means according to the present invention for solving the above-mentioned problems is such that in a battery tray on which a vehicle battery is placed, a part of the periphery of a tray plate on which the battery is placed is The present invention is characterized in that a heat shield plate is integrally installed, and a protruding piece is provided on the upper edge of the heat shield plate to integrally form a clamp portion for clamping the battery cable. .

[0014]

[Operation] With the present invention constructed as described above, a battery tray is formed in which the dish plate, the heat shield plate, and the clamp portion are integrated. By using this battery tray, the battery is protected from the heat radiated from the outer surface of the engine by a heat shield plate provided on a part of the periphery of the plate, and the cables connected to the terminals of the battery are Since the cables are guided and routed by being hooked onto the clamp part formed by the protruding piece, the cables are routed in the same way regardless of the skill level of the operator, and there is no possibility of the cables coming into contact with hot parts. Since there is no part to insert the cable into a hole when routing the cable, the workability of assembling the battery is good.
