Description
Technical Field
[0001] The utility model relates to an aluminum alloy automobile tail plate, in particular to an aluminum alloy automobile tail plate with adjustable lifting angle. Background Art
[0002] A car tail lift is also called a car lifting tail lift, a car loading and unloading tail lift, a lifting tail lift, a hydraulic car tail lift, or a truck tail lift. It is a hydraulic lifting and unloading device installed at the rear of a truck or various vehicles and is powered by an onboard battery. A van with a tail lift installed is not restricted by the site, equipment, or manpower when loading and unloading goods. Even if there is only one person, the cargo can be loaded and unloaded. The use of a tail lift is characterized by fast, safe, and efficient loading and unloading, which can greatly improve the efficiency of transportation and loading and unloading, and save costs. It is one of the necessary equipment for modern logistics and transportation.
[0003] Regarding a lifting structure and a car tailboard with the authorization announcement number CN 218986442 u, the utility model can adjust the height of the car tailboard body according to the specific needs of the user during the use of the device. When adjusting, it is only necessary to turn on the motor 1 and the motor 2, because the bottoms of the motor 1 and the motor 2 are fixed to the mounting shell 1 and the mounting shell 2, which can directly drive the car tailboard body to move upward, or adjust it to a required angle and then move upward, which can more conveniently carry goods, meet the needs of users, and have certain practical effects;
[0004] The lifting and lowering adjustment of the above-mentioned tail board mainly relies on the extension and retraction of the telescopic rod 1 and the telescopic rod 2 to drive the tail board body to lift and lower, so the tail board body does not have the function of bearing heavy objects. Secondly, the angle adjustment of the tail board mainly relies on the extension of the telescopic column to rotate around the central axis to adjust the angle of the tail board body. In this way, the telescopic column needs a certain toughness to cope with the rotation around the central axis or has no toughness and only needs to rotate a certain distance. In this way, the adjustment angle of the tail board is limited, and the supporting effect of the tail board after the angle adjustment mainly relies on the extension and extension limit of the telescopic column. In this way, the tail board does not have the function of weighing and lifting. Utility Model Content

[0024] The lifting assembly 2 includes a fixed shaft 21, which is rotatably connected to the first rotating shaft 22 through a bearing. The two ends of the first rotating shaft 22 are respectively fixedly connected to the upper ends of two L-shaped lifting plates 23.

The two convex slides 24 are respectively sleeved with the convex holes on the two convex hole plates 1. The two convex slides 24 are respectively threadedly connected to the two screw rods 15. For closing the rear tail plate 210, the hydraulic push rod 27 can be controlled to extend. The hydraulic push rod 27 is on the second rotating shaft 26. The rear tail plate 210 on the third rotating shaft 28 and the fixed plate 29 is pushed to rotate upward under the support of the rotating plate 211, the fixed shaft 21 and the first rotating shaft 22, so that the rear tail plate 210 is turned over and fitted on the convex hole plate 1, and then the motor 14 is controlled to start, so that the screw rod 15 rotates to drive the lifting assembly 2 to turn and adjust the rear tail plate 210 and move it upward, so that the rear tail plate 210 moves upward and is inserted into the L-shaped clamping plate 12, so that the rear tail plate 210 can be clamped and restricted to be turned over, so that the rear tail plate 210 is closed.
[0025] The lower side plates of the two L-shaped lifting plates 23 are connected to the limit assembly 25, and the front ends of the lower side plates of the two L-shaped lifting plates 23 are rotatably connected to the two ends of the second rotating shaft 26 through bearings.
