Description

Technical Field

[0001] This utility model relates to the field of low-speed electric vehicle chassis technology, and in particular to a novel low-speed four-wheel shock-absorbing chassis frame. Background Technology

[0002] A four-wheel shock-absorbing chassis is a structural system installed at the bottom of a vehicle to support the body, connect the wheels, and provide shock absorption. It is an important component of the vehicle's driving system and directly affects the vehicle's handling, comfort, and safety.

[0003] Existing four-wheel shock-absorbing chassis mostly use simple spring damping systems, which cannot effectively absorb vibrations under different road conditions, resulting in poor vehicle stability and affecting ride comfort. At the same time, the chassis structure is mostly a single frame design, which is prone to deformation under complex road conditions, affecting the vehicle's service life and safety.

[0004] Existing four-wheel shock-absorbing chassis often employ simple spring damping systems, which cannot effectively absorb vibrations under different road conditions. This results in poor vehicle stability and affects ride comfort. Furthermore, the chassis structure is often a single-frame design, which is prone to deformation under complex road conditions, impacting vehicle lifespan and safety. This solution, by incorporating multiple sets of damping and vibration detection structures, can significantly absorb vibrations experienced by the chassis during movement, enhancing vehicle stability. Simultaneously, it can detect internal pressure and vibration within the chassis when subjected to shocks, preventing chassis deformation that could lead to safety hazards. Utility Model Content
