AI Technical Summary

Technical Problem

Traditional X-ray machine steering and braking structures occupy a large space, making it difficult to meet the requirements of medical equipment for mobility and safety.

Method used

The rear wheel steering and braking structure of the X-ray machine adopts an integrated design, combining a steering motor, sensing components, and a miniature telescopic push rod to achieve the integration of the steering and braking structures. The steering motor drives the connecting shaft to rotate, the sensing components detect the steering angle, and the miniature telescopic push rod drives the D-shaped brake pads to lock or release, achieving precise steering and rapid braking.

Benefits of technology

The number of parts has been reduced, the space occupied has been reduced, and precise ±90° steering control has been achieved, meeting the mobile flexibility and safety requirements of medical equipment.

Abstract

This utility model relates to the field of steering brakes, and more particularly to a rear wheel steering brake structure for an X-ray machine. It includes a rear wheel crossbeam fixedly mounted on the vehicle body, and casters on both sides of the rear wheel crossbeam. A connecting bracket is mounted on the outer side of each caster, and a brake assembly is mounted on the inner side of the connecting bracket at the top of the caster. A connecting piece is fixedly connected to the upper end of the connecting bracket, and a connecting shaft is fixedly connected to the upper end of the connecting piece. The connecting shaft and the end of the rear wheel crossbeam are rotatably connected via a bearing assembly. Steering boxes are fixedly mounted on both sides of the upper end of the rear wheel crossbeam, and a steering motor is fixedly mounted on the surface of the steering box. A sensing assembly is located on the top of the steering box. This utility model reduces the number of parts and space requirements by integrating the steering and braking structures into a single design. Furthermore, the sensor on the steering structure enables real-time feedback control of the steering, achieving precise steering control.
