The output end of the height adjustment unit supports the frame 2. The first connecting rod 5 passes vertically through the top of the support frame 2. The bottom of the first connecting rod 5 is connected to the second connecting rod 8. The second connecting rod 8 passes through the bottom of the support frame 2 and is equipped with wheels 3. The guide cylinder 11 is hinged to the side wall of the support frame 2. The guide rod 14 is slidably installed inside the guide cylinder 11.

By incorporating a buffer component, this device can reduce the impact of lateral impact forces in the lateral direction, mitigate vertical movement jamming, improve the device's buffering effect, and extend the service life of the wheels and their connections.

[0020] At least two sets of buffer components are provided, and the buffer components are arranged symmetrically about the axis of the first connecting rod 5.

[0021] The moving unit also includes a connecting plate 4, a first spring 6, and a second mounting plate 7. The connecting plate 4 is disposed on the top of the support frame 2. The first connecting rod 5 is disposed vertically through the connecting plate 4 and the support frame 2.

When the equipment travels on rough roads, the lateral impact force on the wheel 3 is transmitted to the guide rod 14 through the second connecting rod 8, forcing the first mounting plate 12 to compress the second spring 13, thus achieving lateral buffering; at the same time, the vertical impact force is transmitted through the first connecting rod 5 to cause the second mounting plate 7 to compress the first spring 6, forming a double buffer.

[0023] In this embodiment, a first telescopic sleeve 23 is provided at the bottom of the support frame 2, and the end of the first telescopic sleeve 23 away from the support frame 2 is connected to the wheel 3. The first telescopic sleeve 23 can also serve as a guide and support in the vertical direction.

Lead nuts 18 are symmetrically arranged on both sides of the bidirectional lead screw 17. The lead nuts 18 are hinged to the rotating rod 24 through lead nut seats. The end of the rotating rod 24 away from the lead nuts 18 is hinged to the support plate 20. The connection method between the motor 16, bidirectional lead screw 17, lead nuts 18, and rotating rod 24 in this drive assembly is existing technology and will not be described in detail here. In use, starting the motor 16 drives the bidirectional lead screw 17 to rotate, which in turn causes the two lead nuts 18 to move closer or further apart, causing the rotating rod 24 to rotate and drive the support plate 20 to rise or fall, thereby causing the support frame 2 and the wheels 3 to move up or down to adjust the height of the chassis.

[0026] Wheel 3 is a swivel wheel. Here, wheel 3 is preferably a polyurethane shock-absorbing wheel, support frame 2 is preferably made of aviation aluminum alloy, and the second spring 13 is made of 60Si2MnA material.
