[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Example: See Figure 1-3A car lifting device comprises a bottom plate 1, climbing blocks 2 are arranged on both sides of the upper end of the bottom plate 1, and a storage platform 3 is arranged between the two climbing blocks 2. The two climbing blocks 2 cooperate with each other to guide the vehicle's travel, which is convenient for the vehicle to move and reduces the risk of collision between the vehicle chassis and the lifting equipment. Two lifting structures are arranged on both sides of the storage platform 3. The two lifting structures cooperate with each other to achieve stable lifting of the vehicle. The two lifting structures are respectively installed on both sides of the upper end of the bottom plate 1; the two lifting structures each include: an installation platform 4, a screw module 5, a support frame 6, a sleeper 7 and an adjustment support assembly; the installation platform 4 is fixedly installed on the upper end of the bottom plate 1 and is located on one side of the storage platform 3, and the screw module 5 is vertically installed on the installation platform The upper end of the platform 4 adopts the lifting method of the screw module 5. Even if a sudden power failure occurs, the self-locking function of the screw module 5 can ensure the lifting support stability of the vehicle to prevent the vehicle from falling and being damaged. The support frame 6 is fixedly installed on one side of the driving end of the screw module 5, and the sleeper 7 is movably placed on the upper end of the support frame 6. The sleeper 7 movably placed on the upper end of the support frame 6 can support the wheels of the vehicle to move forward when the vehicle drives onto the device. The wall wheels contact the support frame 6 when moving forward. Since there is a drop between the support frame 6 and the climbing block 2 and the storage platform 3, the sleeper 7 is used to effectively ensure the forward stability of the vehicle. After the vehicle stops, the four wheels of the vehicle are respectively located at the upper ends of the two climbing blocks 2 At this time, the sleeper 7 can be removed or moved to one side, one end of the adjustment support assembly is fixedly installed on the lower wall of the support frame 6, and the other end is movably placed on the upper wall of the support frame 6. The adjustment support assembly includes: an electric push rod 8, a mobile frame 9 and two support blocks 10; one end of the electric push rod 8 is fixedly installed on one side of the driving end of the screw module 5. When supporting and lifting the vehicle, according to the support point position of the vehicle chassis, the mobile frame 9 is driven by the electric push rod 8 to move on the upper end of the support frame 6 until the mobile frame 9 is consistent with the support point position, and the positions of the support blocks 10 in the mobile frame 9 are adjusted respectively until the two support blocks 10 are respectively consistent with the support point position, the mobile frame 9 is placed on the upper end of the support frame 6, and the bottom The center is connected to the telescopic end of the electric push rod 8, and the two support blocks 10 are movably embedded in the two sides of the mobile frame 9. After the adjustment is completed, the vehicle is lifted as a whole through the operation of the screw module 5. A plurality of connecting reinforcement ribs 11 are provided at the connection between the screw module 5 and the mounting platform 4. The connection method of adopting multiple connecting reinforcement ribs 11 can effectively ensure the connection strength between the screw module 5 and the mounting platform 4, and avoid the top of the screw module 5 from shifting inward due to force. One side of the climbing block 2 is conical to facilitate the vehicle to travel to the upper end of the device. A connecting block 12 is provided at the connection between the mobile frame 9 and the electric push rod 8. The connecting block 12 is connected to the mobile frame 9 and the electric push rod 8 to ensure the connection stability between the mobile frame 9 and the electric push rod 8.
