A chassis 100 for carrying a car 200 according to some embodiments of the present application, the chassis 100 comprising a frame 10, a lifting device 20 and a guide 30. Carriage 200 is rotatably coupled to frame 10, lifting device 20 is disposed on frame 10 and coupled to carriage 200 to drive carriage 200 to lift upward relative to frame 10, guide 30 is disposed on frame 10, and carriage 200 is slidably coupled to guide 30 to enable carriage 200 to slide relative to guide 30 during the upward lifting process.

The chassis 100 is used for carrying the carriage 200, the lifting device 20 can drive the carriage 200 to lift upwards relative to the frame 10 and can also drive the carriage 200 to fall back to the frame 10, and the guide member 30 is slidably connected with the carriage 200, so that the guide member 30 has a guiding effect on the carriage 200 in the process that the carriage 200 ascends or falls back relative to the frame 10, which is beneficial to ensuring the stable connection between the carriage 200 and the frame 10, and the vehicle 300 is more stable when unloading.

In some embodiments, the compartment 200 is opened with a first hinge hole 210, the frame 10 has a first fitting hole fitted with the first hinge hole 210, and the compartment 200 is hinged with the frame 10 by means of the first hinge hole 210 and the first fitting hole. In this way, when unloading is required, the carriage 200 can be raised with respect to the frame 10 by the lifting device 20, and when unloading is completed, the carriage 200 can be returned to the frame 10 by the lifting device 20.

In some embodiments, the lifting device 20 includes a driving assembly 21 for driving the car 200 to lift upward relative to the frame 10, and the driving assembly 21 of the base 22 connected to the driving assembly 21 includes a driving member 211 disposed on the base 22, and a driving rod 212 hinged to the driving member 211, wherein an end of the driving rod 212 remote from the driving member 211 is connected to the car 200, and the driving member 211 drives the driving rod 212 hinged thereto to move, thereby driving the car 200 to move, and driving the car 200 to lift or fall back.

In some embodiments, the frame 10 further includes a limiting member 12 partially connected to the base 22 by welding, and another portion of the limiting member 12 is fixed to the frame 10 by a bolt, so that the movement of the lifting device 20 during the driving process can be effectively prevented.

In some embodiments, the car 200 is provided with a sleeving pipe 220, and the driving rod 212 is inserted into the sleeving pipe 220, so that the driving rod 211 drives the car 200 to move correspondingly when the driving rod 212 is driven to move.

Specifically, the driving rod 212 is telescopically sleeved in the sleeving pipeline 220, and when the carriage 200 needs to be lifted, the driving member 211 drives the driving rod 212 to extend so as to support the carriage 200, thereby completing the lifting action of the carriage 200.
