A control mechanism and control method for a carriage tail plate bearing plate

Abstract

The invention discloses a control mechanism of a compartment tail board loading board and a control method. The control mechanism and the control method are used for decreasing the number of linear actuators and reducing strength requirements, so that the cost is reduced. The control mechanism comprises the tail board loading board, a machine frame fixed to a vehicle body, a first lift arm supporting arm, a second lift arm supporting arm, a first telescopic supporting rod, a second telescopic supporting rod, a first linear actuator, a second linear actuator and a telescopic supporting rod push-pull mechanism, wherein the first lift arm supporting arm, the second lift arm supporting arm, the first telescopic supporting rod and the second telescopic supporting rod are arranged between the tail board loading board and the machine frame; one end of the first linear actuator is hinged to the first lift arm supporting arm, and the other end of the first linear actuator is connected to the machine frame through a first swing arm in a pivot-rotating mode; one end of the second linear actuator is hinged to the second lift arm supporting arm, and the other end of the second linear actuator is connected to the machine frame through a second swing arm in a pivot-rotating mode; and the telescopic supporting rod push-pull mechanism can push and pull the first telescopic supporting rod so as to drive the tail board loading board to do turnover movement in loading and unloading positions and in a door closing position.

Description

technical field [0001] The invention relates to a carriage tailgate bearing plate, in particular to a control mechanism and a control method for a carriage tailgate bearing plate. Background technique [0002] Car tail plate load plate is also called car lifting tail plate, car loading and unloading tail plate, lifting tail plate, hydraulic car tail plate, truck tail plate, which is a hydraulic hydraulic system powered by on-board batteries installed on the tail of trucks and various vehicles. Lifting and handling equipment. [0003] Automobile tail lift has the characteristics of fast, safe and efficient, which can greatly improve the efficiency of transportation and loading and unloading. It is one of the necessary equipment for modern logistics transportation. in: [0004] Fast: Just control the lifting and lowering of the tailgate by operating the buttons, and the transfer of goods between the ground and the compartment can be easily realized. [0005] Safety: The use...

Problems solved by technology

[0008] However, most of the existing ones are based on 5 or 4 oil cylinders, two of which are away from the bearing plate's rotating shaft and are used for carrying. It is related to the distribution position on the surface, which makes the oil cylinders used for loading very easy to be crushed by the cargo, causing damage, and the more oil cylinders, the higher the cost

[0009] Although there are existing tailgate bearing plates that only use two oil cylinders, the two oil cylinders are not symmetrically distributed, and the force on one of the oil cylinders is still related to the distribution position of the cargo on the load plate, and it is still easy to be crushed by the cargo
