With continued reference to fig. 1 and 2, the battery compartment of the electric vehicle further includes a locking structure for locking the battery, the locking structure including at least two oppositely disposed stop members, each stop member for pressing against the top of the battery when engaged with the battery for securing the battery within the case 1. Illustratively, in the embodiment of the present application, the number of the limiting assemblies is two, and the two limiting assemblies are located on two opposite side walls of the box body 1. It should be understood that, although two limiting assemblies are shown in fig. 1, the number of the limiting assemblies is not particularly limited in the embodiment of the present application, and the number of the limiting assemblies may be two, four, six, and the like.

As an optional scheme, in the embodiment of the present application, two limiting assemblies are adopted, the number of the sliding guide frames 7 is also two, and the two limiting assemblies and the two sliding guide frames 7 are located on different side walls of the box body 1. Thereby avoiding the interference between the two parts and simplifying the structure of the battery box for conveniently placing and locking the battery to the maximum extent.

With continued reference to fig. 1 and 2, each stop assembly includes: a limit plate 4 slidably fitted on the side wall of the case body 1, and a second elastic member 6 for urging the limit plate 4 to protrude outward in the case body 1.

As an optional scheme, when the limiting plates 4 are arranged, the limiting plates 4 correspond to the limiting grooves 3 one by one, and each limiting plate 4 penetrates through the side wall of the box body 1 and is partially positioned in the corresponding limiting groove 3. It should be understood that, in order to make the limiting plates 4 slide relative to the side wall of the box body 1, through holes are provided on the side wall of the box body 1 for each limiting plate 4 to correspondingly pass through, and the through holes are opened in the limiting grooves 3.

When specifically setting up limiting plate 4, the limiting plate 4 is located the one end of the spacing groove 3 that corresponds and is provided with baffle 5, and baffle 5 links firmly with limiting plate 4. The second elastic piece 6 is an extension spring, the extension spring is sleeved on the limiting plate 4, one end of the extension spring is fixedly connected with the box body 1, and the other end of the extension spring is fixedly connected with the baffle 5.

When the battery box is used, the baffle 5 is pulled, and the limiting plate 4 is driven by the baffle 5 to move outwards from the box body 1, so that the limiting plate 4 does not protrude outwards from the box body 1, a battery can be conveniently placed in the battery box, and the extension spring is stretched to generate elastic deformation. When the baffle 5 is released, the extension spring recovers elastic deformation, the extension spring pushes the limiting plate 4 to reset, so that the limiting plate 4 protrudes outwards again in the box body 1 and is pressed against the top of the battery, and the battery is limited and locked.

When the battery box is disassembled, the baffle 5 is pulled to drive the limiting plate 4 to move outwards of the box body 1 again, and the requirement that the battery is taken out of the box body 1 is met. Set up like this, needn't just can take out the battery from box body 1 with the help of supplementary extracting tool, to the maintenance and the change of battery, provide convenience, holistic operation is more simple and convenient and swift.

Referring to fig. 4, fig. 4 shows a cross-sectional view of the cartridge. In order to improve the safety of the battery, the battery box of the electric vehicle further comprises a buffer structure, and the buffer structure comprises a buffer plate 11 and a first elastic member 10 which are positioned in the box body 1.
