AI Technical Summary

Technical Problem

The braking devices of existing mobile medical X-ray machines cannot effectively adapt to ground variations, resulting in unstable braking performance and affecting equipment safety and user experience.

Method used

An adaptive braking mechanism is adopted, including a support arm, leaf spring, brake pads and a limiting structure. The leaf spring is rotatably connected to the support arm, and multiple brake pads are fixed on the leaf spring. When the support arm moves downward, the brake pads contact the ground, and the leaf spring adaptively adjusts under the restriction of the limiting structure to ensure braking stability.

Benefits of technology

On uneven ground, the adaptive braking mechanism ensures that multiple brake pads are in contact with the ground through the rotation and deformation of the leaf springs, improving braking stability and safety, reducing sudden changes in pedal force, and enhancing the safety and user experience of the equipment.

Abstract

The utility model provides a kind of self-adapting brake mechanism and mobile X-ray machine, self-adapting brake mechanism includes support arm, the plate spring being rotatably connected with support arm, brake pad being connected in plate spring and the limiting structure for limiting the rotation angle of plate spring, the number of brake pad is at least two, support arm can be moved downward to make brake pad contact with ground.The self-adapting brake mechanism and mobile X-ray machine provided by the utility model, when ground is uneven, plate spring rotates relative to support arm, multiple brake pads can contact with ground, and brake can be self-adaptively adjusted.Moreover, when ground unevenness is too high, the angle that plate spring can rotate cannot meet demand, plate spring itself will be deformed, further adapt to the condition of ground, and then ensure the stability of brake.
