[0002] In related technologies, during vehicle testing, to verify the vehicle's maximum load-bearing capacity and performance, it is necessary to install the vehicle and load it, simulating a fully loaded vehicle. This is typically done using sandbags, sand buckets, or other counterweights. However, due to the vehicle's large mass, carrying these counterweights is time-consuming and labor-intensive. Furthermore, sandbags and sand buckets are difficult to secure to the seats and can easily move during testing, potentially impacting or endangering the test.

[0003] A counterweight unit is provided in the related technology, which is mainly composed of a counterweight weight frame and counterweight weights, wherein there are several guide locking blocks on both sides of the counterweight weight frame, wherein a concave platform is formed between the two groups of guide locking blocks, which cooperates with the boss in the side guardrail column, and the bolt hole in the guide locking block cooperates with the long hole in the side guardrail column to achieve connection, and the side guardrail column is connected to the whole vehicle or frame. By adopting this technical solution, the weight of the load can be adjusted by adjusting the number of weights, and it is easy to carry.

[0004] When adopting the above technical solution, during installation, the side guardrail column needs to be connected to the entire vehicle or frame by bolts, and then the counterweight frame needs to be connected to the side guardrail column by bolts. In order to ensure a firm installation, multiple connection positions are set, which results in low disassembly and assembly efficiency of the counterweight unit and the entire vehicle or frame, affecting the test efficiency.
