Equalizer bar for automobile power lift gate and assembly method thereof

Abstract

The invention provides an equalizer bar for an automobile power lift gate, and an assembly method thereof, and belongs to the technical field of automobiles. The equalizer bar for the automobile powerlift gate is matched with electric support rods, and comprises an outer casing pipe, an inner casing pipe, a spring, an outer guide pipe, an inner guide pipe and a screw rod which are sleeved in sequence; the outer casing pipe is internally provided with a damper connected one end of the screw rod, and the other end of the screw rod is in threaded connection with the inner guide pipe; the end ofthe outer guide pipe is fixedly provided with a small ball seat component in a clamping mode, and the end of the inner casing pipe is fixedly provided with a big ball seat component in the clamping mode; and the big ball seat component is in threaded connection with the inner guide pipe. The equalizer bar has the beneficial effects that the equalizer bar has the advantages of the stable and firm overall structure, high structure strength and motion transmission efficiency, and simple assembly; the equalizer bar is used in cooperation with the electric support rods, so that the torques of the both sides of the lift gate keep balance, and the opening and closing of the lift gate are more stable; the deformation risk of the power lift gate is reduced, and meanwhile impact damage to the electric support rods and a metal plate of the lift gate by bumping vibration is reduced; and the service life of the power lift gate is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a balance bar for an electric tailgate of an automobile and an assembly method thereof. Background technique [0002] Nowadays, with the improvement of people's living standards, the requirements for car configuration are getting higher and higher, and the electric tailgate has been favored by customers. At present, the electric tailgate of automobiles on the market uses a single electric strut drive system and a double electric strut drive system; one end of the single electric strut drive system on the market uses an electric strut, and the other end uses a combination of a gas strut and a mechanical spring. The air strut in the rod is greatly affected by temperature, and the value of the support force changes unevenly. When the output force value of the struts on both sides differs greatly for a long time, the tailgate is easily distorted and deformed, and the requirements...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a balance bar for an electric tailgate of an automobile, which mainly solves the problem of long-term opening and closing of the electric tailgate due to the fact that the expansion and contraction of the traditional balance bar is greatly affected by the external temperature and the structural strength of the balance bar is insufficient. The door causes its deformation. The purpose is to design a balance bar through which the damper can simulate the motor rotation damping torque and the static stop rotation torque. It is used in conjunction with the electric strut to keep the torque on both sides of the tailgate in balance. , the two ends of the balance bar are clamped to fix the small ball seat assembly and the large ball seat assembly respectively, which improves the strength and stability of the connection, reduces the risk of deformation of the electric tailgate as a whole, and reduces the production cost
