A fixing device for new energy vehicle maintenance

By using a screw-driven fixing device, which connects the fixed shaft to the tire center hole and utilizes the elastic inclined surface assembly, the problem of unstable tire fixing in new energy vehicles is solved. This enables the tire to self-adjust and adjust its angle, improving maintenance efficiency and convenience.

AI Technical Summary

Technical Problem

Existing tire fixing devices for new energy vehicles lack effective positioning and support for the tire center hole, resulting in unstable fixing. They are particularly incompatible with different tire sizes and cannot adjust the tire angle or height, affecting maintenance efficiency and ease of operation.

Method used

The fixing device, driven by a lead screw, is connected to the center hole of the tire through a fixed shaft. It uses elastic elements and inclined plane components to fix and limit the tire at multiple angles. Combined with motor drive to adjust the tire angle, it achieves adaptive and adjustable functions.

Benefits of technology

It enables stable fixing of tires of different specifications for new energy vehicles, improves the versatility and ease of operation of maintenance, enhances the flexibility of tire angle adjustment, and improves maintenance efficiency.

Abstract

This invention relates to the technical field of fixing devices for automobile maintenance, specifically a fixing device for the maintenance of new energy vehicles, comprising: a base, a support frame provided on one side of the top of the base, a lead screw provided on one side of the middle of the support frame, a lifting block slidably connected to the lead screw, a drive motor fixed in the middle of the outer side of the lifting block, a rotating shaft inserted into the end of the drive motor, a fixed shaft connected to the end of the rotating shaft, and multiple sets of first telescopic grooves formed around the middle of the fixed shaft; the beneficial effect is that the fixing device for the maintenance of new energy vehicles proposed in this invention first drives the lead screw to rotate by starting the lead screw motor, causing the lead screw to drive the fixed shaft connected to the outer side of the rotating shaft to descend, making the fixed shaft parallel to the center hole of the tire, then aligning the center hole of the tire with the fixed shaft, and pushing the tire laterally, so that the fixed shaft is inserted into the center hole of the tire, at which time the inner wall of the center hole of the tire is aligned with the inclined surface of the inclined plate.
