Detailed Implementation
[0022] This utility model provides a vehicle body reinforcement tie rod device, which overcomes the shortcomings of the prior art where the vehicle body is deformable; it achieves the technical effect of strengthening the vehicle body structure, effectively preventing vehicle body deformation, and improving safety.
[0023] The overall concept of the technical solution of this utility model embodiment is as follows:
[0024] In the body of new energy vehicles, especially in the engine compartment, three telescopic adjustment assemblies are installed. These three assemblies are arranged in a triangular pattern to complement the body structure, utilizing the principle of triangular stability to strengthen the body structure. The telescopic adjustment assemblies can adjust the extension and retraction states of the left and right positioning blocks and the tie rod, facilitating installation and removal. After determining the positions of the left and right positioning blocks, when the tie rod is rotated forward, the left and right screws move towards the left and right positioning blocks respectively; when the tie rod is rotated in the reverse direction, both the left and right screws move towards the center position of the tie rod.
[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
