Balance rod for electric tail door of vehicle

Abstract

The invention discloses a balance rod for an electric tail door of a vehicle. The balance rod for the electric tail door of the vehicle comprises a first pipe sleeve of the balance rod, wherein a first accommodating cavity is arranged in the first pipe sleeve; a second sleeve pipe capable of enabling the balance rod to extend and retract is slidably connected into the first accommodating cavity; the outer side wall of one end of the first pipe sleeve is detachably connected with a first ball head through a first clamp buckle mechanism; a first through hole allowing one end of the second sleeve pipe to extend out of the first accommodating cavity is formed in the end, far away from the first ball head, the first pipe sleeve; the end, away from the first ball head, of the second sleeve pipe is rotationally connected with a second ball head; a second accommodating cavity with one side communicating with the first accommodating cavity is formed in the second sleeve pipe; air springs are arranged in the first accommodating cavity and the second accommodating cavity; first springs are arranged on the outer side wall of the air spring in the circumferential direction; and a first cushion plate for preventing the end part of the first springs from being in direct contact with the bottom surface of the first ball head is arranged on the bottom surface of the first ball head in the first accommodating cavity.

Description

technical field [0001] The invention relates to the technical field of a vehicle electric tailgate balance bar, in particular to a vehicle electric tailgate balance bar. Background technique [0002] A balance bar is often added to the vehicle tailgate in the prior art, and the electric or manual opening and closing of the tailgate is assisted by adding the balance bar, so that the opening process of the tailgate is smoother. In the existing balance bar, springs are often added to ensure the elasticity of the inner sleeve of the balance bar, and because the spring is installed inside, the two ends of the spring are often directly in contact with the inner bottom surface of the internal accommodation cavity of the balance bar. Compatible. When the spring is squeezed, the spring will generate twisted tension due to the squeezed force, and the twisted tension of the spring will directly push the bottom surface inside the balance bar. Over time, the inner wall of the inner cav...

AI Technical Summary

Problems solved by technology

Over time, the inner wall of the inner cavity of the balance bar will be worn out, and finally, abnormal noise will occur when the spring is twisted again, which seriously affects the customer experience.
