Description

Technical Field

[0001] This utility model relates to the field of lifting tail plate technology, specifically a lifting tail plate based on an electric servo cylinder. Background Technology

[0002] The tailgate is a hydraulic lifting and unloading device installed at the rear of a truck. Its core function is to enable the rapid loading and unloading of goods, which can significantly improve the efficiency of loading and unloading goods in logistics transportation. Therefore, it is widely used in various freight scenarios.

[0003] Most of the tailgates currently in use rely on hydraulic mechanisms as their power source, which results in several technical shortcomings. In terms of electronic control precision, the viscosity of hydraulic oil changes significantly with temperature variations. Its fluidity decreases at low temperatures, and leaks and contamination in the oil circuit can further delay the transmission of control signals, leading to a decrease in precision. Regarding starting speed, the response speed of the hydraulic system is affected by factors such as pump capacity and component wear. At low temperatures, the problem of slow starting becomes more pronounced as the oil becomes more viscous. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tailgate based on an electric servo cylinder, which has the advantages of quick tailgate deployment, accurate positioning, stable and reliable structure, and easy remote control. It solves the problems of existing tailgates, which usually use hydraulic mechanisms to provide power, resulting in low electronic control accuracy, slow start-up speed, and lack of protective structure that makes them easily damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The lifting tailgate based on an electric servo cylinder includes a rear section of a carriage and an adjustment assembly. The adjustment assembly is located at the front end of the rear section of the carriage. The adjustment assembly includes a tailgate. A shaft connector is located at the rear end of the tailgate and is rotatably connected to the tailgate and fixedly connected to the rear section of the carriage. A folding plate is located at the front end of the tailgate and is rotatably connected to the tailgate. A servo electric cylinder is located below the tailgate, and the cylinder body of the servo electric cylinder is rotatably connected to the shaft connector. The output end of the servo electric cylinder is rotatably connected to the lower end face of the tailgate.

[0006] Preferably, both the tail plate and the folding plate are provided with folding fixing ears on one side, and the two folding fixing ears are fixedly connected to the tail plate and the folding plate respectively.

[0007] It is worth noting that the folding fixing ear is used for binding and fixing the external steel rope.

[0008] Preferably, the two folding fixing ears are connected by a steel rope.

[0009] It is worth noting that the two folding fixing lugs, when bound with steel ropes, improve the structural stability of the tail plate and folding plate after folding, and reduce swaying.

[0010] Preferably, a limit protection frame is provided below the servo electric cylinder, and the limit protection frame is integrally formed with the tail plate.

[0011] It is worth noting that the limit protection frame is used to limit the tailplate, prevent the tailplate from rotating excessively downwards, and improve the structural support strength of the tailplate.

[0012] Preferably, a reinforcing rib is provided between the tail plate and the limiting protection frame, and the two ends of the reinforcing rib are fixedly connected to the tail plate and the limiting protection frame.

[0013] It is worth noting that the reinforcing ribs improve the structural strength of the limiting and protective frame and reduce metal fatigue at the structural connections.

[0014] Preferably, positioning frames are provided on both sides of the folding plate, and the positioning frames are fixedly connected to the folding plate.

[0015] It is worth noting that the positioning bracket is used for connecting the pin rod.

[0016] Preferably, the positioning frame is provided with a pin rod inside; one end of the pin rod is provided with a pin hole, and the pin hole is integrally formed with the tail plate.

[0017] It is worth noting that the pin rod is inserted into the pin hole after passing through the positioning frame, thereby realizing the unfolding function of the tail plate and folding plate.

[0018] Preferably, the pin rod is inserted into the pin hole through the pin hole.

[0019] It is worth noting that after the pin is pulled out of the pin hole, the folding plate can rotate, which makes it easier to fold and store the folding plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared to traditional hydraulic cylinders, the servo electric cylinder of this invention offers more precise control. The output end of the servo electric cylinder extends and pushes the tail plate upwards for support and unfolding. The folding plate is then manually rotated and extended, and a pin is inserted into the positioning hole after passing through the positioning frame, thus achieving the unfolding function of the tail plate and folding plate. The servo electric cylinder responds more quickly, enabling the tail plate to achieve smooth and precise movements in various operations, meeting the detailed requirements for position and movement during loading and unloading of different goods. In terms of energy consumption and environmental protection, the servo electric cylinder does not require continuous energy consumption, resulting in higher energy efficiency. It also eliminates the risk of hydraulic oil leakage, reducing energy waste and avoiding environmental pollution, aligning with modern environmental protection concepts. Structurally, its integrated design makes it more compact, occupying less space, and facilitating simple and convenient installation. Subsequent maintenance also eliminates the need for complex piping and oil tank components required by hydraulic cylinders, significantly reducing maintenance difficulty and workload. Furthermore, the servo electric cylinder is easier to interface with intelligent control systems, enabling automated operation and remote monitoring. It also has stronger adaptability to different temperatures and environments. In long-term use, these advantages make its overall performance far superior to traditional hydraulic cylinders.

[0021] The limit protection frame is used to limit the tailplate, prevent the tailplate from rotating excessively downwards, and improve the structural support strength of the tailplate. Attached Figure Description
