Description

Technical Field

[0001] The utility model relates to the technical field of power units for vehicle tailgates, and particularly relates to an integrated power unit for a vehicle tailgate. Background Art

[0002] A vehicle tailgate device is a vehicle-mounted hydraulic lifting loading and unloading platform mainly installed at the rear of a freight truck. Developed to date, it has been widely used in logistics-related industries such as enterprise transportation, material transfer, transit warehouses, airports, and material delivery. It greatly reduces the work intensity of loading and unloading personnel, reduces the number of workers in loading and unloading operations, reduces the labor cost for enterprises, and can significantly improve the loading and unloading efficiency. Currently, it has become an indispensable loading and unloading device for freight vehicles in many scenarios.

[0003] The power unit of a vehicle tailgate device is the core component of the vehicle tailgate. By using the cooperation of a motor, a rising solenoid valve, a flipping solenoid valve, and a descending solenoid valve to control the delivery of hydraulic oil, it provides kinetic energy for the vehicle tailgate to complete various actions such as rising, descending, and flipping of the vehicle tailgate, meeting the various action requirements for cargo loading and unloading. The power unit of the vehicle tailgate is usually fixedly installed at the bottom or side of the freight truck carriage and is immovable. Existing power units, for example, a vehicle tailgate hydraulic power system with the application number CN201720506078.X, in addition to the power unit, also requires an electric control box and a spring wire handle switch to control the lifting and the tipping oil cylinder and the support plate surface of the vehicle tailgate to complete the operation. Its installation efficiency is low and the labor cost is high; moreover, the electric control box and the spring wire handle switch supporting the traditional vehicle tailgate power unit are both ordinary physical buttons and cables, which are easily aged under the influence of the climate environment. There are phenomena such as the contacts of the buttons getting stuck and not resetting, and the spring wire of the spring wire handle switch is commonly broken and the cable is short-circuited due to the high frequency of pulling during long-term use, posing a considerable safety hazard.
