When repairing the electric vehicle frame, it is often necessary to use a supporting device to lift the electric vehicle frame first, and then the front and rear wheels can be repaired. For example, as shown in the existing patent technology: After searching, the China Patent Network discloses an electric vehicle frame support mechanism (public announcement number CN219902089U). When such a device is in use, the support assembly is used to support the bottom of the electric vehicle frame, and then the automatic adjustment clamping of the abutment device on both sides is used to firmly abut on both sides of the electric vehicle frame, so that the electric vehicle frame is firmly fixed on the support assembly. At the same time, through the setting of the lifting device, the height of the electric vehicle frame can be adjusted, so it can better meet the needs of maintenance personnel.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the electric vehicle frame support mechanism adopted in the existing market: the existing method of lifting the electric vehicle frame by using the bottom support method has a limited lifting height, and after lifting to a certain height, due to the upward shift of the center of gravity, its autonomous stability is poor, and it is easy to overturn, which is not conducive to the maintenance work of the staff. To this end, those skilled in the art provide an electric vehicle frame support mechanism to solve the problems raised in the above-mentioned background technology. Utility Model Content
