Embodiment Construction

[0012] like figure 1 As shown, the battery box includes an inner box 1 and an outer box 2 . What adopted in the present invention is a kind of drawer design, wherein the outside of inner box body 1 is provided with three rollers 9, and the inside of outer box body 2 is provided with three slideways 3, therefore, inner box body 1 can be compared with outer The casing 2 slides. Applying an outward pulling force on the inner box body 1 can pull out the inner box body 1 to replace the battery, which is convenient and quick. The inner box body 1 and the outer box body 2 have only one degree of freedom, that is, they can only be pulled out and pushed back. It is conceivable that other designs are also possible, for example, slideways 3 may also be provided outside the inner box body 1 , and rollers 9 may be arranged inside the outer box body 2 .

[0013] In order to discharge the heat generated when the battery works so as not to threaten the safety of the vehicle, the rear part ...

Abstract

The invention relates to a battery box for an electric vehicle, which includes an inner box and an outer box body, the inner box body is slidably arranged in the outer box body, and a positioning device is arranged between the inner box body and the outer box body; it also includes a secondary locking mechanism, Including lock blocks and lock pins respectively arranged on the inner and outer boxes; the lock blocks include handles, bars with ratchets, connecting rods, inner and outer sleeves, connecting rods connecting handles and bars, and inner sleeves The sleeve covers the bar and can move relatively longitudinally along the bar, and the inner wall of the inner sleeve is provided with a stopper that can engage with the ratchet, the outer sleeve covers the inner sleeve and can move relatively longitudinally along the inner sleeve; the lock pin It includes a body and a lock bar. The body has a lock hole for accommodating the inner sleeve. The body and the lock bar engage to define a key hole for inserting a key. The lock bar is provided with a ratchet lock engaged with the ratchet. Thus, a battery box that can be firmly positioned is realized, so that the battery can be firmly arranged in the battery box, and will not move and collide with the battery box when the vehicle vibrates, turns, and the like.

Description

technical field [0001] The invention relates to a battery box, in particular to a battery box used on an electric vehicle. Background technique [0002] Energy issues have challenged the era of fuel vehicles. A pure electric vehicle is a vehicle that obtains power from a single vehicle energy source, the battery, uses an electric motor as a prime mover, and can drive on the road. It is a "zero-emission" vehicle with low noise, comfortable and clean, easy to operate and maintain. It is the most ideal and promising green transportation tool to replace fuel vehicles in the 21st century. The key technology for the development of pure electric vehicles is the battery. The difficulty of placing the battery on the electric vehicle is that the working environment of the battery is harsh, mud, water, changes in external temperature difference, and vibration of the vehicle body are likely to affect the working characteristics of the battery and the safety of the battery. Therefore, ...
