[0002] When a car needs to be repaired, it is often lifted up by a lift. Existing lifts usually include a hydraulic rod and a lifting plate. The car is placed on the top of the lifting plate, and the lifting plate is driven upward by the hydraulic rod, thereby driving the car to move up automatically, making it convenient to repair the bottom of the car.

[0003] The patent specification with the announcement number CN219297055U discloses an automatic filtering system and method for car washing water, including a base plate, the bottoms of both sides of the base plate are fixedly connected with a fixing plate, the side of the fixing plate away from the center of the base plate is fixedly connected with a water tank, the top of the water tank is fixedly connected with an infusion device, and the front end of one side of the base plate is fixedly connected with a sewage pipe. Through the use of the cylinder, the gas rod can drive the liquid plate to move, so that the nozzle can be located below the lifted vehicle, and then through the use of the liquid pump, the liquid extraction pipe can extract the liquid inside the water tank, and then the liquid can be discharged to the inside of the liquid plate through the liquid discharge pipe, and finally the bottom of the lifted vehicle can be sprayed and washed through the nozzle, so as to remove impurities under the vehicle, which can facilitate the user to inspect and repair the vehicle, thereby improving the practicality of the equipment.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned automatic car washing water filtering system and method have the following problems: the device pumps water into the liquid plate through a water pump, and sprays water through a nozzle, and drives the liquid plate and the nozzle to move through a gas rod to increase the water spraying range of the nozzle. In order to save space, the gas rod of the device is shorter, which leads to a limited movement range of the liquid plate and the nozzle, so that water can only be sprayed to a part of the bottom of the vehicle, thereby reducing the cleaning effect of the device on the bottom of the vehicle. In view of this, a lift for automobile maintenance is provided to overcome the above-mentioned defects. Utility Model Content
