Abstract
The utility model directs to a safety protection device for a power supply group battery of an electric bus, pertaining to an accessory of an electric bus. The utility model is intended to resolve the insulating safety problems of the power supply group battery of an electric bus. The safety protection device is composed of a battery box placed with a power supply group battery; the battery box is connected with the bus body with a fixed seat. An insulating layer is arranged between the bus body and the fixed seat and the battery box. The battery box is provided with an insulating layer on the inner wall. The utility model provides a protection with two insulating layers, avoiding the occurred discharge between the metal connecting components and effectively enhancing the safety performance of the whole bus.
Description
Technical field
The utility model relates to a kind of accessory of electrobus, specifically is a kind of safety device of power battery pack of electrobus.
Background technology
The power battery pack of electrobus is the energy source of car load, compare with the startup battery of traditional fuel oil passenger vehicle, its voltage height (hundreds of volt), intensity of current big (hundreds of peace), therefore the insulating power of passenger vehicle are had relatively high expectations, in case between power battery pack and the vehicle body electric discharge phenomena take place, chaufeur and passenger's safety will be subjected to great threat.
The utility model content
In order to solve the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of safety device of electrobus power battery pack.
The technical solution of the utility model is: a kind of safety device of electrobus power battery pack, it is characterized in that: it comprises the battery box of placing power battery pack, battery box is by permanent seat and body contact, be provided with insulating barrier between vehicle body and permanent seat and the battery box, the battery box inwall is provided with insulating barrier.
Insulating barrier between described vehicle body and permanent seat and the battery box is a High-Voltage Insulation bakelite layer.
Insulating barrier on the described battery box inwall is acidproof electro-insulating rubber layer.
The beneficial effects of the utility model are: it protects by dielectric layers, avoided the generation of electric discharge phenomena between the attachment hardware, improve the safety performance of car load effectively, guaranteed the safety precaution rank of passenger and operating personal, realized the safety precaution purpose of electrobus basically.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Among the figure: 1 battery pack, 2 acidproof electro-insulating rubber layers, 3 battery boxs, 4 vehicle bodies, 5 High-Voltage Insulation bakelite layers, 6 permanent seats.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified,
As shown in drawings.
The safety device of this electrobus power battery pack, it comprises the battery box 3 of placing power battery pack 1, battery box 3 links together by permanent seat 6 and vehicle body 4, be provided with insulating barrier between vehicle body 4 and permanent seat 6 and the battery box 3, this insulating barrier is a High-Voltage Insulation bakelite layer 5, the inwall of battery box 3 is provided with insulating barrier, and this insulating barrier is acidproof electro-insulating rubber layer 2.
Realize the primary insulation protection by acid-resisting rubber layer 2 between battery pack 1 and the battery box 3 like this; Realize the secondary insulating protection by High-Voltage Insulation bakelite layer 5 between battery box 3 and permanent seat 6 thereof and the vehicle body 4, be that battery box 3 all is connected by insulating material with all connecting portions of vehicle body 4, avoided the generation of electric discharge phenomena between the attachment hardware, thereby realized the safety precaution of battery pack 1, the safety that has improved car load.
As other embodiments, two insulating barriers also can adopt other insulating materials.
