3results about How to "Improve static stiffness" patented technology

This disclosure relates to a rear subframe and a vehicle. The rear subframe includes longitudinal beams, a rear crossbeam, and a rear stabilizer bar bracket. The rear crossbeam is connected to the longitudinal beams. The rear stabilizer bar bracket is connected to both the longitudinal beams and the rear crossbeam, forming a cavity together with the longitudinal beams and the rear crossbeam. The rear stabilizer bar bracket is an integrally molded structural component, suitable for mounting a rear stabilizer bar. Through the above technical solution, the rear subframe provided by this disclosure can provide more reliable support for the rear stabilizer bar bracket, helping to improve the static stiffness, strength, and durability of the rear stabilizer bar bracket. Furthermore, connecting the rear stabilizer bar bracket to both the longitudinal beams and the rear crossbeam enhances the connection reliability between the longitudinal beams and the rear crossbeam, enabling the rear subframe to better withstand various impact loads and vibrations generated during vehicle operation. This ensures that the overall structure of the rear subframe has high structural strength and durability, contributing to improved overall vehicle performance.

This invention discloses a geometrically nonlinear, high-load, high-isolation and vibration-damping robot wheel-leg mechanism, including a thigh, a lower leg, a wheel, a crank, a connecting rod, an elastic device, a damping device, a first joint motor, and a second joint motor. The first and second joint motors are located inside a housing. The first joint motor is connected to the upper end of the robot's thigh and drives its rotation. The lower leg is rotatably connected to the lower end of the thigh, and the wheel is connected to the lower end of the lower leg. The upper end of the crank is connected to the second joint motor, and the lower end of the crank is rotatably connected to the upper end of the connecting rod. The lower end of the connecting rod is rotatably connected to the upper end of the lower leg. The damping device and the elastic device connect the lower leg and the connecting rod to achieve vibration isolation and reduction. This invention improves the robot's vibration isolation and reduction performance when traversing bumpy roads or walking on legs, making the robot body more stable and reducing the impact on the motors.

The application discloses a magnetic nonlinear stiffness large-damping high-isolation and damping robot wheel-leg mechanism, which comprises a thigh, a shank, a wheel, a crank rod, a connecting rod, a magnetic device one, a magnetic device two, a damping device, a first joint motor and a second joint motor. The first joint motor and the second joint motor are located in a box body, the first joint motor is connected with the upper end of the thigh of the robot and drives the rotation of the thigh, the shank connecting point is rotationally connected with the lower end of the thigh, and the wheel is connected with the lower end of the shank. The upper end of the crank rod of the crank rod is connected with the second joint motor, the lower end of the crank rod is rotationally connected with the upper end of the connecting rod of the connecting rod, and the lower end of the connecting rod is rotationally connected with the upper end of the shank. The damping device, the magnetic device one and the magnetic device two are connected with the shank and the connecting rod respectively, and isolation and damping are realized. When the robot passes through a bumpy road surface or walks in a foot mode, the isolation and damping performance of the robot is improved, the fuselage is more stable, and the impact on the motor is reduced.
