In particular, the fourth sleeve 64 may be made of a rigid material, and has a characteristic of good rigidity. An internal thread formation is provided in the fourth sleeve 64 to facilitate threaded engagement with the third fastener 53.

Alternatively, the second brackets 42 and the third brackets 43 may be disposed alternately along the length direction of the frame 7, so that the operating space for installing the second brackets 42 and the vehicle body 2 can be increased, and the convenience in connecting the frame 7 and the vehicle body 2 can be improved.

Alternatively, the third bracket 43 may include a connection plate and a reinforcement plate; one end of the connecting plate can be connected with one side of the battery pack 3 facing the frame 7, and the other end of the connecting plate is arranged at the bottom of the frame 7 and is used for being fixed with the frame 7; adjacent sides of the reinforcing plate may be connected to a side of the battery pack 3 facing the frame 7 and the connection plate, respectively.

In the embodiment of the present utility model, the connection plate may function to connect the battery pack 3 and the frame 7. The reinforcing plate can strengthen the structural strength of the connecting plate, and further improve the reliability of the connection between the battery pack 3 and the frame 7.

Specifically, the reinforcing plate can be a triangular plate, so that the structure of the reinforcing plate is stable. A reinforcing plate may be provided at a side of the connection plate facing the second bracket 42 to reasonably use the gap between the frame 7 and the battery pack 3.

Optionally, the vehicle may further include a sealing member, where the sealing member may be connected to the vehicle body 2 and the battery pack 3, respectively, so that the battery pack 3 may be connected to the bottom of the vehicle body 2 and enclose the vehicle body 2 to form a closed space, so that a sealed space may be provided for a passenger, and a lower plate structure of the vehicle body 2 and a gap between the vehicle body 2 and the battery pack 3 may be eliminated, which is beneficial to reducing a space in a height direction of the skateboard chassis.

Specifically, the sealing member may be a ring of sealing strips disposed on the upper surface of the battery pack 3, or may be a sealant, or the like, which may be specifically disposed according to actual requirements, and the embodiment of the present utility model is not specifically limited thereto.

The vehicle disclosed by the embodiment of the utility model has the following advantages:
