For convenience of explanation, the following embodiment will be described taking the example in which the lock mechanism 30 is used to lock the vehicle 01.

Fig. 1 is a schematic structural diagram of a vehicle 01 according to some embodiments of the present application; fig. 2 is a schematic diagram of a partial structure of a vehicle 01 according to some embodiments of the present application; FIG. 3 is a schematic illustration of a partial cross-section of a vehicle 01 according to some embodiments of the present application; FIG. 4 is a schematic illustration of a partial cross-section of a vehicle 01 according to some embodiments of the present application; fig. 5 is a schematic partial cross-sectional view of a vehicle 01 according to some embodiments of the present application. Referring to fig. 1 to 5, a vehicle 01 specifically includes a first bearing member, a second bearing member, and a locking mechanism 30, wherein one of the first bearing member and the second bearing member is a vehicle body 20, the other of the first bearing member and the second bearing member is a chassis 10, and the locking mechanism 30 is used for locking and clamping the first bearing member and the second bearing member to ensure stability after the vehicle body 20 and the chassis 10 are matched.

In the embodiment of the present application, when the first bearing member is the vehicle body 20, the second bearing member is the chassis 10, and when the first bearing member is the chassis 10, the second bearing member is the vehicle body 20. The embodiments of the present application will be described by taking the first bearing member as the vehicle body 20 and the second bearing member as the chassis 10. Meanwhile, the chassis 10 may be a separate chassis 10 structure or a chassis 10 structure integrated with the battery pack 50, and the embodiment of the application is described by taking the chassis 10 integrated with the battery pack 50 as an example, and the outer case of the battery pack 50 may be a part of the chassis 10, so as to save space and cost. The battery pack 50 can be used for supplying power to the vehicle 01, so that the vehicle 01 can be ensured to normally run. Meanwhile, when the chassis 10 is not integrated with the battery pack 50, the locking mechanism 30 can directly lock and clamp the chassis 10 and the vehicle body 20, and when the chassis 10 is integrated with the battery pack 50, the locking mechanism 30 can lock and clamp the battery pack 50 and the vehicle body 20, and can also lock and clamp the chassis 10 and the vehicle body 20, and can be selected according to requirements. Of course, in other embodiments, the battery pack 50 may be disposed on the vehicle body 20, so as to ensure that the battery pack 50 can reliably supply power to the vehicle 01, and the embodiment is not limited thereto.

It should be noted that, in other embodiments of the present application, the first bearing member and the second bearing member may be other structures besides the vehicle body 20 and the chassis 10, and the first bearing member and the second bearing member may be matched with each other, and the locking mechanism 30 may lock and clamp the two when they are matched.

In addition, it should be noted that in the embodiment of the present application, the vehicle 01 may further include a controller (not shown) and a motor (not shown) according to the requirements, wherein the controller is used to control the battery pack 50 to supply power to the motor, for example, for operation power requirements during starting, navigation and driving of the vehicle 01. Of course, in some embodiments of the present application, the battery pack 50 may not only serve as an operating power source for the vehicle 01, but also as a driving power source for the vehicle 01, instead of or in part instead of fuel oil or natural gas, to provide driving power for the vehicle 01.

Referring to fig. 3 to 5 again, in the present embodiment, the locking mechanism 30 specifically includes a first clamping member 301 and an elastic component 302.

Specifically, the first clip 301 includes an engagement portion 3011, a stopper portion 3012, and a connection portion 3013, the connection portion 3013 has a long rod-like structure, and the connection portion 3013 is connected between the engagement portion 3011 and the stopper portion 3012. The engagement portion 3011 may be engaged or released, and in particular may be engaged or released by either one of the vehicle body 20 and the chassis 10. In the following embodiments of the present application, in order to facilitate connection between the vehicle body 20 and the chassis 10, the engaging portion 3011 is described as an example that can be engaged by the chassis 10, and in other embodiments, the engaging portion 3011 can be engaged by the vehicle body 20 to achieve engagement between the vehicle body 20 and the chassis 10, and the present embodiment is not limited thereto.

The elastic member 302 has a structure with elastic deformation capability, and one end of the elastic member 302 is engaged with the stop portion 3012, and the other end of the elastic member and the engaging portion 3011 together form a clamping space 303. That is, the elastic member 302 can clamp the chassis 10 and the vehicle body 20 together with the engagement portion 3011. Specifically, when the vehicle body 20 and the chassis 10 are connected, the engaging portion 3011 engages with a side of the chassis 10 facing away from the vehicle body 20, the elastic member 302 engages with a side of the vehicle body 20 facing away from the chassis 10 in an abutting manner, and at this time, the holding space 303 formed by the elastic member 302 and the engaging portion 3011 can hold the partial structures of the vehicle body 20 and the chassis 10 located in the holding space 303, so that the vehicle body 20 and the chassis 10 can be relatively fixed. When both the vehicle body 20 and the chassis 10 need to be disassembled, the engaging portion 3011 is released so that the holding space 303 can release the vehicle body 20 and the chassis 10.

By this arrangement, on the one hand, when the engagement portion 3011 is engaged by one of the body 20 and the chassis 10 of the vehicle 01, the clamping space 303 formed by the engagement portion 3011 and the elastic member 302 can clamp the body 20 and the chassis 10, so that the reliability of the vehicle 01 can be ensured.
