[0002] The related art (Announcement No.: CN221165862U) discloses a lifting logistics transport vehicle used in a logistics storage workshop, including a transport vehicle body. Four universal wheels are fixedly connected to the bottom surface of the transport vehicle body. A protective mechanism and a lifting mechanism located below the protective mechanism are arranged above the transport vehicle body. The protective mechanism includes a clamping portion and a buffer portion located below the clamping portion. The buffer portion includes a support plate, a placement box is arranged above the support plate, four dampers are fixedly connected to the top surface of the support plate, and the first compression springs are sleeved on the surfaces of the four dampers. The bottom end surface of the first compression spring is fixedly connected to the top surface of the support plate, and the top end surface of the damper output rod and the top end surface of the first compression spring are both fixedly connected to the bottom surface of the placement box.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The lifting logistics transporter used in the logistics warehouse workshop uses four compression springs to buffer and four dampers to suppress vibration, thereby playing a shock-absorbing role to protect the transported goods. However, the four compression springs and four dampers can only work as a whole. When any universal wheel is hit, it will affect the other universal wheels. As a result, the entire device will vibrate significantly and cannot better adapt to complex road conditions.
