A kind of end plate structure of conventional high-speed magnetic levitation beam
The present invention belongs to the technical field of beam gap devices for common high-speed maglev bridges, and specifically relates to a common high-speed maglev beam end slat structure, including a bridge pier, a T-shaped slat and two continuous beam bodies; the T-shaped slat includes a T-shaped slat track plate beam and a T-shaped slat small pier column connected to the bottom surface of the T-shaped slat track plate beam; the two ends of the T-shaped slat track plate beam are respectively arranged on two continuous beam bodies, and the top of the bridge pier is pre-embedded with a grip sleeve matching the T-shaped slat small pier column, the T-shaped slat small pier column passes through the beam gap between the two continuous beam bodies and extends into the grip sleeve, and the bottom of the T-shaped slat small pier column is connected to the top of the bridge pier. The present invention reduces the vibration of the electromagnet by improving the influence of the beam end angular deformation and reducing the beam gap, thereby improving the driving comfort of the maglev train and improving the safety and stability of high-speed driving.

An all-terrain vehicle with a crash avoidance mechanism
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.
