[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form advanced technical principles, new technologies, and new structures. Automotive maintenance is a general term for vehicle maintenance and repair. It is to use technical means to troubleshoot a malfunctioning vehicle, identify the cause of the malfunction, and take certain measures to eliminate the malfunction and restore it to a certain performance and safety standard. Lifting devices are important auxiliary equipment in automotive repair and maintenance.

At the same time, when repairs need to be made to a precise position on the bottom of the vehicle, the fixed spacing cannot provide sufficient flexibility and space for precise positioning, which is not conducive to the smooth progress of the repair work. In order to solve the above problems, a lifting device for repairing new energy vehicles is proposed.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

A slide groove 2 is opened in the base 1, and both sides of the mobile platform 3 extend into the slide groove 2 to facilitate the smooth movement of the mobile platform 3. The push rod 1 4 and the push rod 2 5 are hinged, and the two ends of the push rod 2 5 are respectively hinged to the side where the mobile platform 3 and the lifting platform 8 are close to each other. The connecting rod 6 is fixed between the two push rods 1 4, and the bottom of the electric cylinder 7 is hinged to the top of the mobile platform 3. The telescopic end of the electric cylinder 7 is hinged to the connecting rod 6. A guide groove 9 is provided on the side where the lifting platform 8 and the mobile platform 3 are close to each other. The two ends of the push rod 1 4 are respectively slidably connected to the two guide grooves 9. Sliding blocks are provided in the two guide grooves 9 and are hinged to the two ends of the push rod 1 4. Through the extension and contraction of the electric cylinder 7, the push rod 1 4 is pushed to swing, and under the guiding action of the guide groove 9, the push rod 2 5 is driven to rise and fall together, thereby realizing the lifting of the lifting platform 8;

[0027] It should be noted that the use of the electric cylinder 7 to drive the lifting reduces the risk of hydraulic oil leakage and contamination of the battery or electrical system compared to the hydraulic system;

[0028] Reference Figure 1 、 2 The driving assembly includes a screw rod 24, a guide rod 25, a gear 26, a chain 27, a gear 28, a support frame 29, and a motor 2 30.
