Abstract

PROBLEM TO BE SOLVED: To provide a structure for protecting a battery for auxiliary equipment that requires less number of components, that has fewer limits in assembling the components, and that is low-cost. SOLUTION: In vehicles including an electric vehicle or a hybrid vehicle in which a battery 60 for auxiliary equipment is arranged in the rear of rear wheel housings 52 of the vehicle, an exhaust duct 34 connected to a high-voltage battery cooling device 30 is provided in a gap between a buffer bracket 20 mounted in the rear of the rear wheel housing 52 and a vertical wall 12 mounted in the front of a battery bracket 11. Even if a large impact against the vehicle causes the battery 60 to move forward, the impact energy is absorbed by the duct 34, because the battery 60 moves while crushing the duct 34.

Since the high-voltage battery has a high voltage and cannot be used as a power source for operating auxiliary equipment such as a lamp or a horn of a vehicle, a small motor or an electromagnetic actuator, a conventional engine such as a gasoline engine or a diesel engine is used as a power source. Like an automobile, an electric vehicle or a hybrid vehicle is also equipped with a small accessory battery.

In a passenger car or a van-type car as an electric vehicle or a hybrid vehicle, a high-voltage battery is often mounted in a vehicle room (a passenger room or a luggage room). Therefore, the auxiliary battery is also mounted in the vehicle interior. In this case, the space inside the rear wheel house is mainly used for the vehicle interior.

Therefore, there is a possibility that the vehicle interior will be corroded by the liquid leakage. Therefore, conventionally, as a mounting structure for protecting the accessory battery 60 from impact, as shown in FIG. 6, a battery bracket 511 for mounting the accessory battery 60 is mounted on the floor 55 at the rear of the rear wheel house 52. An impact absorbing bracket 562 is attached to a vertical wall 512 provided at the front of the battery bracket 511. Further, a cushioning bracket 56 provided at the front of the shock absorbing bracket 562 and the rear of the rear wheel house 52 is provided.
A cushioning material 563 made of chip urethane is attached to the space between the two. The shock absorbing bracket 562 and the cushioning material 563 constitute an energy absorbing member that absorbs the shock energy when the accessory battery 60 moves due to a shock to the vehicle.

を最小限に押さえることができる。However, when a large impact is applied to the vehicle, the auxiliary battery 60 moves further forward with the battery tray 61 together with the battery tray 61 as shown in FIG.
The vertical wall 12 attached to the vehicle is pushed down and climbs, and the exhaust duct 34 of the high-voltage battery cooling device 30 is crushed and stopped. When the auxiliary equipment battery 60 pushes down the vertical wall 12 and crushes the exhaust duct 34, the impact energy is absorbed and the auxiliary equipment battery 60 is not hindered at all. Damage can be minimized.

減が可能となった。As described above, in a vehicle such as an electric vehicle or a hybrid vehicle in which the auxiliary battery 60 is disposed behind the rear wheel house 52 of the vehicle, the buffer bracket 20 attached to the rear of the rear wheel house 52 and the front of the battery bracket 11. Since the exhaust duct 34 connected to the high-voltage battery cooling device 30 is provided in the gap between the vertical wall 12 and the auxiliary battery 60, the auxiliary battery 60 may be moved forward even if a large impact is applied to the vehicle. Machine battery 6
Since 0 moves while crushing the exhaust duct 34, it stops by absorbing its impact energy. Accordingly, the auxiliary battery 60 is not damaged at all, the damage due to the impact can be minimized, and the subsequent repair and restoration of the vehicle can be performed at a minimum, and the repair cost can be reduced. It has become possible.

用バッテリの保護が可能となった。The auxiliary battery protection structure according to the present invention is an auxiliary battery protection structure mounted near a high-voltage battery mounted on an electric vehicle or a hybrid vehicle. Between a vertical wall standing in front of a battery bracket on which the battery is mounted and a buffer bracket having a surface facing the vertical wall, which is provided in a main part of the vehicle body at a predetermined interval in front of the vertical wall. In the protection structure for an auxiliary battery in which an energy absorbing member is interposed, a hollow ventilation duct communicating between a vertical wall of the battery bracket and an opposing surface of the buffer bracket and communicating with a cooling device for cooling the high-voltage battery. When the auxiliary battery moves due to a large impact on the vehicle, it moves while deforming and crushing the vertical wall of the battery bracket and the ventilation duct. Energy can be absorbed and damage to the auxiliary battery can be minimized, the number of parts is small, assembly restrictions are reduced, the cost is low, and the auxiliary battery can be protected. .
