For example, the chassis 9 is provided with a receiving space for receiving a box, and the box is disposed in the receiving space of the chassis 9 and connected to the chassis 9 by welding or screw fastening. Through arranging the box in the accommodation space of chassis 9, can make full use of whole car space, reach the effect that does not occupy the effective space of chassis 9 top equipment.
Wherein the top of the box is provided with an opening and a cover plate 19 capable of opening and closing the opening. The mounting seat 1 and the battery box 3 are arranged in the box body. The mounting seat 1 is connected with the box body. For example, the mounting base 1 may be connected to the housing by means of a welded connection or a threaded fastener connection.
Through setting up the box, can play the effect of protection battery box 3. For example, it is possible to prevent erosion or damage of electrical components inside the battery case 3 by dust, moisture, or the like, thereby extending the service life of the battery case 3. And because battery box 3 sets up in chassis 9, so be closer to ground, through setting up the box, can avoid the grit that the tire arouses to hit battery box 3 to reach the effect of protection battery box 3.
Alternatively, the cover 19 may be hingedly or slidably connected to the housing. When the battery is required to be replaced, the box body is opened, and when the battery is not required to be replaced, the box body is closed. For example, when the cover is hinged to the box, the cover plate 19 may be driven to rotate by a driving cylinder to open and close the opening above the box. When the cover body is connected with the box body in a sliding mode, the cover plate 19 can be driven to move horizontally through the horizontal pushing cylinder or the electric cylinder, and therefore the opening above the box body is opened and closed.
Optionally, a sealing material, such as a sealing strip, may be provided between the cover plate 19 and the tank to enhance the sealing effect.

Similarly, the two corresponding side walls of the box body are provided with guide grooves 21. In order to reduce the interaction force between each guide groove 21 and the slide block 23, i.e. to share the force, two slide blocks 23 are disposed on two opposite side walls of the battery box 3. Similarly, two guide grooves 21 are arranged on two corresponding side walls of the box body.
In some embodiments provided by the present invention, the rechargeable battery device further comprises a spring-loaded detent pin 25. It should be noted that the spring positioning pin 25 belongs to the prior art, and generally includes a sleeve body, a head portion and a spring. The first end of the sleeve body is provided with an opening, the head part is slidably arranged at the first end of the sleeve body, and part of the head part extends out of the opening. One end of the spring is propped against the head part, and the other end of the spring is propped against the second end of the sleeve body. Typically, the head may be a steel ball or a round-head cylinder.
Wherein, the spring positioning pin 25 is arranged on the groove wall of the guide groove 21, and the head of the spring positioning pin 25 extends into the guide groove 21 to be used for abutting against the sliding block 23. The head of the spring positioning pin 25 abuts against the sliding block 23, so that the sliding block 23 can play a role in buffering when sliding along the guide groove 21, and the battery box 3 is prevented from falling too fast to generate impact.
The slide block 23 is provided with a concave 47 matched with the head of the spring positioning pin 25, and when the battery box 3 is abutted against the mounting seat 1, the head of the spring positioning pin 25 is placed in the concave 47. Through the head cooperation that sets up pit 47 and spring locating pin 25, can play the effect to battery box 3 location, prevent that battery box 3 from appearing rocking.
