Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle maintenance technology, and in particular to a safety lifting device for new energy vehicle maintenance. Background Technology

[0002] New energy vehicles have battery packs and numerous circuit components installed at their bottom, requiring extra caution when lifting them for maintenance. Currently, most new energy vehicle lifting operations utilize lifts; however, existing lifts only have four support points that contact the vehicle, and the spacing between these points is not adjustable, making it difficult to tailor the spacing to different vehicle models. Furthermore, the limited number of support points results in high pressure at each individual point, potentially causing deformation at the point of contact with the vehicle's underside. Therefore, there is an urgent need to develop a safety lifting device for new energy vehicle maintenance that allows for easy adjustment of support points, enabling lifting of different vehicle models, providing multi-point support, reducing pressure on individual support points, and preventing damage to the vehicle's underside. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this utility model is to provide a safety lifting device for the maintenance of new energy vehicles, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A safety lifting device for repairing new energy vehicles includes a gantry frame, a lifting mechanism, a crossbar, and an adjustable support mechanism. A lifting mechanism is installed on each of the left and right sides of the gantry frame. A crossbar is fixedly connected to each lifting mechanism. Multiple adjustable support mechanisms are installed on each crossbar. Each adjustable support mechanism includes: a sliding sleeve, a tube, a telescopic leg, a pin, a socket, a locking block, and a rotating shaft. The sliding sleeve is slidably mounted on the crossbar. A tube is fixed to the front of the sliding sleeve. A telescopic leg extending to the outside is slidably mounted inside the tube. The pin passes through the tube and the telescopic leg. Multiple sockets are provided on the tube for the pin to pass through. A rotating shaft is fixed to one side of the locking block and is rotatably connected to the sliding sleeve. Multiple slots are provided on the crossbar for the locking block to be inserted.

[0006] Preferably, a rubber pad is fixed to the upper front end of the telescopic leg.

[0007] Preferably, the distance between two adjacent sockets is 5cm.

[0008] Preferably, the two lifting mechanisms are arranged symmetrically about the center line of the gantry.

[0009] Preferably, the lifting mechanism includes a drive motor, a lead screw, a threaded sleeve, a base plate, a slider, and a slide rail. The drive motor is fixed inside the gantry frame, the lead screw is rotatably connected inside the gantry frame, the output shaft of the drive motor is fixed to the lead screw, a threaded sleeve is installed on the lead screw, a base plate is fixed to the front side of the threaded sleeve, the crossbar is fixed to the base plate, and two sliders are fixed to the rear side of the base plate. Each slider is slidably mounted on a slide rail, and the slide rail is fixed inside the gantry frame.

[0010] Preferably, a motor controller is installed on the side of the gantry frame, and the two drive motors are driven synchronously by the motor controller.

[0011] The beneficial effects of this utility model are as follows: When using this safety lifting device for new energy vehicle maintenance, the new energy vehicle is driven to the bottom of the gantry. The locking block is unscrewed from the slot, and the sliding sleeve is moved on the crossbar to adjust the position of the telescopic leg. After it is in place, the locking block is inserted back into the slot so that the sliding sleeve cannot move on the crossbar. Then, the pin is removed, and the position of the front end of the telescopic leg is adjusted to adjust the support position according to the condition of the bottom of the vehicle. After adjustment, the pin is inserted again. Finally, the drive motor drives the lead screw to rotate, which in turn drives the threaded sleeve and base plate to move upward. The base plate then drives the crossbar to move upward, and the crossbar drives the adjustable support mechanism to move upward. The rubber pads on the telescopic leg gradually contact the bottom of the vehicle, and the telescopic leg gradually lifts the vehicle. In summary, this utility model facilitates the adjustment of support points to lift different vehicle models; multi-point support reduces the pressure on individual support points and prevents damage to the bottom of the vehicle.

Each adjustable support mechanism 4 includes: a sliding sleeve 401, a sleeve 402, a telescopic leg 403, a pin 404, a socket 405, a locking block 406, and a rotating shaft 407. The sliding sleeve 401 is slidably mounted on the crossbar 3. The front side of the sliding sleeve 401 is fixed with a sleeve 402. A telescopic leg 403 extending to the outside is slidably installed inside the sleeve 402. A rubber pad 4031 is fixed to the upper front end of the telescopic leg 403. When supported, the rubber pad 4031 contacts the bottom of the car to provide a certain degree of protection. The pin 404 passes through the sleeve 402 and the telescopic leg 403. The sleeve 402 is provided with a plurality of insertion holes 405 for the pin 404 to pass through. The distance between two adjacent insertion holes 405 is 5cm. A rotating shaft 407 is fixed to one side of the locking block 406. The rotating shaft 407 is rotatably connected to the sliding sleeve 401.

Then, pull out the pin 404 and adjust the position of the front end of the telescopic leg 403 to adjust the support position according to the condition of the bottom of the car. After adjustment, insert the pin 404. Finally, the drive motor 201 drives the lead screw 202 to rotate, which in turn drives the threaded sleeve 203 and the base plate 204 to move upward. The base plate 204 drives the crossbar 3 to move upward, which in turn drives the adjustable support mechanism 4 to move upward. The rubber pad 4031 on the telescopic leg 403 gradually contacts the bottom of the car, and the telescopic leg 403 gradually lifts the car up.
