Embodiment Construction
[0022] The core of the present invention is to provide a high-voltage protection device for electric vehicles, in order to open the high-voltage protection cover before the battery box cover needs to be opened, so as to ensure that the battery box cover can only be opened when the high-voltage circuit is disconnected. Open to improve the reliability of installation protection and reduce potential safety hazards. Another core of the present invention is to provide an electric vehicle including the above high voltage protection device.
[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Please refer to figure 1 with figure 2 , figure 1 It is a structural schematic diagram of a specific embodiment of the high voltage protection device provided by the present invention; figure 2 for fi...

The invention discloses an electric automobile and a high-voltage protection device thereof. The high-voltage protection device comprises a battery protection shell, wherein an opening of the battery protection shell is fixedly connected with an aluminum seat; the aluminum seat is fixedly connected with a base; an oscillating bar type travel switch is mounted on the base; a protection cover is detachably mounted on the aluminum seat; when the protection cover is mounted on the aluminum seat, the oscillating bar type travel switch is closed to connect a high-voltage loop; when the protection cover and the aluminum seat is separated from the aluminum seat, the oscillating bar type travel switch is flicked off to disconnect the high-voltage loop; the protection cover is detachably and fixedly connected with a battery upper cover through a connection piece. Therefore, as the protection cover presses the battery cover, and is detachably connected with the battery upper cover, the battery upper cover can be only detached after the protection cover is detached, and the danger of electric shock caused by independent detaching of the battery upper cover is avoided; the mounting protection reliability is improved, and a potential safety hazard is reduced.
Description
technical field [0001] The invention relates to the technical field of high voltage protection, in particular to a high voltage protection device for electric vehicles. The present invention also relates to an electric vehicle comprising the above-mentioned high voltage protection device. Background technique [0002] As one of the core components of pure electric vehicles and hybrid vehicles, the power battery is the energy center of electric vehicles. Since the voltage of the power battery is generally above 300V, once a person accidentally touches the high voltage, it will cause serious electric shock injury. In the prior art, according to the safety requirements of the battery pack, a cover switch is added at the high-voltage connection position of the battery pack to ensure that the battery pack has no high-voltage output to the outside when the protective cover at the high-voltage connection position is opened. However, the high-voltage protective cover and the batter...
