AI Technical Summary

Technical Problem

Existing gimbal camera lenses are prone to cause gear damage, wear acceleration, vibration and noise problems, increased manufacturing costs, large space occupation, insufficient thermal effect and reverse driving capabilities under high loads.

Method used

A low-torque gimbal camera device is designed to drive the large gear through pinion, increase the gear contact area, reduce torque output, reduce wear and vibration, and achieve smaller physical space occupation and better heat dissipation through the design of arc racks and spherical components.

Benefits of technology

It effectively reduces wear and vibration of gears, extends service life, reduces noise and thermal effects, and improves reverse driving capabilities. It is suitable for application scenarios where large torques are not required but fast reactions are required.

Abstract

The utility model provides a low-torque pan-tilt camera device which comprises a support, a spherical groove corresponding to a spherical assembly is arranged on the support, the spherical assembly is located on the inner side of the spherical groove, a plurality of tooth grooves are formed in the outer side wall of the spherical assembly, and a plurality of clamping grooves are formed between the tooth grooves and the outer side wall of the spherical assembly. An arc-shaped rack for driving the spherical assembly to rotate is formed; a gear is fixedly arranged at the power output end of the motor, and the gear is meshed with the arc-shaped rack; the camera lens is located on the inner side of the spherical assembly. The utility model has the beneficial effects that the transmission ratio is small, that is, the output rotating speed is high, the torque is small, the shaking of the pan-tilt camera lens in the rotating process is avoided, and the transmission mechanism is suitable for high-speed and small-torque transmission application scenes.
