The lifting assembly 2 is used to connect the top cover 102 and the bed frame 3, and drive the bed frame 3 to lift through the lifting assembly 2.

[0024] Specifically, along the height direction of the vehicle body main body 101, the top cover 102 is mounted at the top of the vehicle body main body 101.

[0025] Along the height direction of the vehicle body main body 101, the top cover 102 has a moving degree of freedom relative to the vehicle body main body 101, that is, the top cover 102 can be lifted relative to the vehicle body main body 101, so that the mounting space 103 is formed between the top cover 102 and the vehicle body main body 101.

[0026] The height of the mounting space 103 along the height direction of the vehicle body main body 101 changes with the lifting of the top cover 102.

[0027] The lifting assembly 2 is located in the mounting space 103, and the fixed end of the lifting assembly 2 is at least partially connected with the top cover 102.

[0028] The bed frame 3 is located in the mounting space 103, and the bed frame 3 is connected with the driving end of the lifting assembly 2, so that the bed frame 3 is driven by the lifting assembly 2 to lift relative to the vehicle body main body 101.

[0029] Under the action of the lifting assembly 2, the bed frame 3 comprises a storage state and a use state. Along the height direction of the vehicle body main body 101, the position of the bed frame 3 in the storage state is closer to the top cover 102 than the position of the bed frame 3 in the use state.

[0030] Specifically, when the bed frame 3 is in the storage state, the bed frame 3 is located at the end of the installation space 103 towards the top cover 102, at this time, the distance between the upper end surface of the bed frame 3 and the lower end surface of the top cover 102 is small, so as to facilitate the storage of the bed frame 3.

[0031] When the bed frame 3 is in the use state, the bed frame 3 is located at the end of the installation space 103 towards the vehicle body main body 101, at this time, the distance between the upper end surface of the bed frame 3 and the lower end surface of the top cover 102 is large, facilitating the user to lie on the bed frame 3.
