Abstract

The invention relates to an electric supporting device. The electric supporting device comprises a shell assembly, a motor assembly, a screw rod assembly, a gas spring and a nut assembly. The shell assembly is cylindrical. The motor assembly is axially arranged inside the shell assembly. The screw rod assembly is rotationally arranged in the shell assembly and is connected with an output shaft atone end of the motor assembly. One end of the gas spring is arranged in the screw rod assembly in a penetrating mode. One end of the nut assembly sleeves the screw rod assembly in a threaded mode andis limited by the shell assembly in the circumferential direction, and the other end of the nut assembly is connected with the other end of the gas spring. The invention provides a design method for replacing a pre-tightening mechanical spring with the gas spring with constant air pressure output as a main supporting mechanism. The electric supporting device has the beneficial effects that the structure is simple, the product production and assembly processes are simplified, the automatic production is realized, the product consistency, the stability and the safety are improved, and meanwhile,the product cost can be reduced.

Description

technical field [0001] The invention relates to a supporting device, in particular to an electric supporting device. Background technique [0002] At present, most electric support devices such as vehicle tailgates are supported by preloaded mechanical springs driven by motor power, so as to realize the opening and closing of passenger car tailgates. The steel spring is a mechanical spring, and its movement speed is fast. Once the electric support device is damaged, the energy-storing steel spring is likely to jump out rapidly, which is easy to cause injury to nearby personnel, and there is a certain potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved electric support device. [0004] The invention provides an electric support device, which includes a housing assembly, a motor assembly, a screw assembly, a gas spring and a nut assembly; the motor assembly is installed in the hous...
