The utility model discloses a modularization friction damper convenient to maintain and replace, including base, the top one end fixedly connected with backplate subassembly of base, and the four corners of backplate subassembly are connected the one end of double -end stud through screw thread structure respectively, and the outer cover of double -end stud is provided with the sleeve, and the one end of sleeve abuts backplate subassembly, and the other end of sleeve abuts has panel subassembly, and is equipped with the sliding component between backplate subassembly and panel subassembly, and is equipped with the friction module in sliding component. The utility model discloses the whole detachable setting, has reduced the time and cost of overall replacement of friction damper, when needing to maintain or replace friction module, need not to remove the whole damper from the structure, only need to operate to specific module, can greatly improve the maintenance efficiency, has reduced the operation difficulty under high altitude or narrow space, and the modular design makes every component can be replaced and upgraded independently, when the wear and tear or need technical update of certain part, can replace the part alone.

This application discloses an all-terrain vehicle with an anti-collision mechanism, relating to the field of all-terrain vehicles. It includes a vehicle body and an anti-collision mechanism installed at the bottom of the body. The anti-collision mechanism includes a mounting base, a rotating box, lateral support wheels, and a diagonal bar. The rotating box contains an adjustment assembly. Through the arrangement of an electric push rod, diagonal bar, rotating box, limit seat, inner support spring, and lateral support wheel, the rotation angle of the rotating box can be adjusted, thereby adjusting the tilt angle of the lateral support wheel. This facilitates use and adaptability to different road conditions, providing stable lateral support force and preventing rollover. Rotating the rotating block with a wrench or other tools drives the worm gear, which in turn drives the worm wheel, which in turn drives the threaded rod. This causes the compression disc to move on the outer surface of the threaded rod. After the compression disc moves, the compression force on the top of the compression spring is adjusted, thereby adjusting the preload of the compression spring to adapt to different driving conditions.

This invention belongs to the field of battery pack vibration damping technology, and specifically relates to an adjustable nonlinear damping energy storage battery, comprising a battery pack, a battery frame, and a battery housing, wherein the battery housing is fitted and fixed to the outside of the battery frame. This invention, by incorporating linear and nonlinear damping components, provides better protection for the battery pack. Furthermore, the two nonlinear damping frames within the nonlinear damping component, in conjunction with a coil spring, an offset turntable, and a crank, constitute a dual-end damping system for the battery pack, further enhancing the overall damping effect and structural stability. In this invention, the crank drives the offset turntable to rotate, causing the reverse force generated by the coil spring to exhibit nonlinear damping characteristics, effectively attenuating vibration energy at different frequencies. Moreover, the U-shaped block and adjusting screw allow for adjustment of the coil spring's coiling degree, thereby adjusting the preload of the coil spring to accommodate battery packs of different weights.
