Automobile electric tailgate stay

Abstract

The invention belongs to the technical field of tail-gate stay bars of cars and particularly relates to an electric tail-gate stay bar of the car. A fixed sleeve is fixedly installed on the side, close to a first end cap, in a first outer pipe, a shaft positioning assembly used for preventing a lead screw from being ejected under the effect of a spring assembly and being separated from a gearbox is installed on the fixed sleeve, and guiding protrusions extending in the axial direction are installed on the outer wall of the side, close to a second end cap, of the first outer pipe in a spaced mode in the peripheral direction; and guiding grooves being matched with the guiding protrusions on the first outer pipe are formed in the whole section of the inner wall of the second outer pipe in the axial direction. According to the electric tail-gate stay bar of the car, structures of the electric stay bars on the two sides of a tail gate are the same, deformation is not caused by uneven stress of the tail gate, and noise is small; a key portion adopts a thread and riveting structure, so that the condition that the key portion is ejected by elastic force of a spring, and thus the stay bars lose efficiency or generate risks is avoided; the fixing modes of the screw rod and the fixed sleeve adopt a bearing pad structure for fixing, and the stay bars are not prone to be ejected; and the electric tail-gate stay bars have water-proof structural design, and it is ensured that a stay bar motor cannot lose efficiency due to water leakage.

Description

technical field [0001] The invention belongs to the technical field of automobile tailgate stays, and more specifically relates to an automobile electric tailgate stay. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The tailgate strut is an important part of the opening and closing of the tailgate of the car. In high-end cars, the electric tailgate design is often used, that is, the opening and retracting of the strut is controlled by the motor to realize the automatic opening and closing of the tailgate of the car. [0004] Existing car tailgate usually adopts a one-side strut, and the other side is designed with a pneumatic spring or spring to ensure the force balance when the tailgate is opened. The work of a single strut cannot ensure that both sides are in place at the same time, or the reached position i...

Problems solved by technology

[0006] In addition, the structure of the traditional strut is unreasonable, the limit of the inner rod of the strut is unreasonable, and it is easy to pop out, and there is no rotation design between the inner and outer tubes.

[0007] More importantly, there is no anti-lock design between the traditional strut and the motor, that is, when the external force causes the strut to lock, the motor will still rotate and cause damage to the motor
