Description

Technical Field

[0001] This utility model relates to truck tailgate technology, and in particular to a tailgate load-bearing plate mechanism with adjustable length. Background Technology

[0002] A truck tailgate, also known as a truck lifting tailgate, is a hydraulic lifting and loading / unloading device powered by the vehicle's battery, installed at the rear of trucks and various vehicles. It is a self-contained unloading device on the truck, avoiding reliance on forklifts or other handling equipment. This allows for convenient and quick loading and unloading of goods anytime, anywhere, effectively ensuring that the truck's work efficiency is not reduced due to loading and unloading issues.

[0003] Currently, when transferring cars into trucks via the tailgate, the length of the tailgate is often limited, which restricts the car transfer process. Therefore, this utility model proposes a tailgate load-bearing plate mechanism with adjustable length to meet the existing needs. Utility Model Content

[0004] The purpose of this utility model is to provide a tail plate load-bearing mechanism with adjustable length to solve the problem that the length of the existing tail plate load-bearing plate is not easy to adjust.

[0005] To address the aforementioned problems, this utility model provides an adjustable-length tailplate support mechanism, comprising a mounting frame installed at the rear of a truck. Vertical grooves are provided on both sides of the mounting frame, and vertically movable vertical rods are installed within these grooves. A support tailplate is located at the bottom of each of the two vertical rods. One side of the support tailplate is hinged to each of the two vertical rods. Hydraulic cylinders are hinged to both sides of the upper surface of the support tailplate. The free end of the piston rod on each hydraulic cylinder is hinged to the top of the corresponding vertical rod. Two sliding grooves are provided on the support tailplate, and extension plates are slidably connected within these grooves. A support plate is fixed to the inner top of each sliding groove.

[0006] The adjustable-length tail plate load-bearing mechanism provided by this utility model also has the following technical features:

[0007] Furthermore, there are two extension plates, each extending out of one end of the load-bearing tail plate and fixedly connected by a connecting rod.

[0008] Furthermore, a pad is fixed to one end of the extension plate that extends out of the load-bearing tail plate, and a top plate is fixed to the pad. The lower side of the top plate can contact the upper surface of the load-bearing tail plate.

[0009] Furthermore, a protrusion is provided on the side of the top plate away from the pad plate, and two blocks corresponding to the protrusion are fixed on one side of the load-bearing tail plate, and the two protrusions can contact the corresponding blocks respectively.

[0010] Furthermore, the bottom of the load-bearing tail plate is threaded with two clamping studs, and the free ends of the two clamping studs can respectively abut against the lower side of the corresponding extension plate.

[0011] Furthermore, a ramp block is fixed to one side of the extension plate extending out of the load-bearing tail plate.

[0012] This utility model has the following beneficial effects: When it is necessary to transport a car to the compartment inside the truck, by lowering the load-bearing tailgate to the bottom and allowing two extension plates to slide out from the load-bearing tailgate, the hydraulic cylinder can adjust the angle of the load-bearing tailgate, thereby facilitating the driver to move the two wheels on the same side of the car to the corresponding extension plates and support plates. The extension plates can extend the length of the load-bearing tailgate, achieving the function of length adjustment, avoiding the problem of inconvenience in transportation due to the length of the car. Then, by raising the height of the load-bearing tailgate to the compartment of the truck, the car can be driven into the truck, thereby facilitating the transfer and transportation of the car.

A rotatable lead screw is provided in the mounting frame 1, and the lead screw is threadedly connected to the vertical rods 3. A motor is fixedly installed at the bottom of the mounting frame 1, and the output end of the motor is fixedly installed to the lead screw. By rotating the lead screw, the vertical rods 3 can be moved up and down. A bearing tail plate 4 is provided at the bottom of the two vertical rods 3. One side of the bearing tail plate 4 is hinged to the two vertical rods 3 respectively. Hydraulic cylinders 5 are hinged to both sides of the upper surface of the bearing tail plate 4. The free end of the piston rod on the hydraulic cylinder 5 is hinged to the top of the corresponding vertical rod 3. Two slids 6 are provided on the top, and extension plates 7 are slidably connected inside the slids 6. A support plate 8 is fixed to the top of the inner side of the slids 6. When it is necessary to transport a car to the compartment inside the truck, the load-bearing tailgate 4 is lowered to the bottom and the two extension plates 7 slide out from the load-bearing tailgate 4. The hydraulic cylinder 5 can adjust the angle of the load-bearing tailgate 4, so that it is easy to drive the two wheels on the same side of the car to move onto the corresponding extension plates 7 and support plates 8. The extension plates 7 can extend the length of the load-bearing tailgate 4, so that the length can be adjusted, avoiding the problem of inconvenience in transportation due to the length of the car. Then, by raising the height of the load-bearing tailgate 4 to the compartment of the truck, the car can be driven into the truck, thus facilitating the transfer and transportation of the car.

[0019] In one embodiment of this application, preferably, there are two extension plates 7. The two extension plates 7 extend out of one end of the load-bearing tail plate 4 and are fixedly connected by a connecting rod 9, so that the two extension plates 7 can move synchronously and are easy to operate.

[0020] In one embodiment of this application, preferably, a pad 10 is fixed on one end of the extension plate 7 that extends out of the load-bearing tail plate 4, and a top plate 11 is fixed on the pad 10. The lower side of the top plate 11 can contact the upper surface of the load-bearing tail plate 4. Through the setting of the pad 10 and the top plate 11, a further supporting and protective function can be achieved, and the structure is more stable.
