Description

Technical Field

[0001] The utility model relates to a lightweight, high-load-bearing, anti-fatigue frame assembly, belonging to the technical field of frame assemblies. Background Art

[0002] The vehicle may include a frame assembly that supports vehicle components and systems, such as a propulsion system, a braking system, seats for occupants of the vehicle, and the like. The frame assembly may be a unitary structure in which the vehicle body (e.g., side rails, pillars, roof rails, etc.) serves as the vehicle frame, and the vehicle body (including side rails, pillars, roof rails, etc.) may be integral, i.e., a continuous one-piece unit, and as another example, the frame assembly may have a non-load-bearing body structure (also known as a cab-frame split structure), in other words, the body and frame are separate components, i.e., modular, and the body is supported on and attached to the frame.

[0003] For example, a frame assembly disclosed in application number: CN109649496A, by providing a protective plate and a shock-absorbing spring and sponge inside the protective plate, when the protective plate is hit, the protective plate and the shock-absorbing spring and sponge inside the protective plate cooperate with each other to block the transmission of the collision force and reduce the impact of the collision on the frame, and the replacement cost of the protective plate is low, which effectively solves the problem of frame damage and high maintenance cost; wherein, by providing an upper fixed block and a lower fixed block, the upper fixed block increases the contact area with the crossbeam and improves the stability of the connection; in addition, by providing an inner spring, an outer spring, a telescopic column and a sleeve, when the front baffle contacts the obstacle, the front baffle transmits the collision force to the telescopic column and the outer spring after being subjected to force, and the outer spring is compressed after being subjected to force, and drives the inner spring to be compressed, and the inner spring generates a corresponding reaction force when being compressed, which effectively reduces the damage to the device caused by the collision force.

[0004] Based on the search and analysis, the existing technology still has deficiencies:

[0005] The structure of the prior art is a solid structure, which is heavy during use, and the bottom plate is inconvenient to install. There is no shock-absorbing structure between the frame and the body, resulting in high cost and poor load-bearing effect of the frame. Therefore, a lightweight, high-load-bearing and fatigue-resistant frame assembly is needed to improve the above-mentioned deficiencies. Utility Model Content
