Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0024] like Figure 1 to Figure 4 As shown, the rear back limiting device includes a limiting block 1 arranged on the inner panel of the back door and a limiting seat 2 arranged on the side wall; A slide block 4 sliding in the limit seat 2, a spring 5 is arranged between the slide block 4 and the limit seat 2. The limit block 1 and the slider 4 of the limit seat 2 are engaged to limit the left and right, up and down movement of the back door; it can suppress the up and down, left and right shaking of the back door to the greatest extent during the driving process of the car. Effectively limit the position to improve the durability and reliability of the door; eliminate the abnormal noise caused by the shaking of the back door and improve the NVH performance of the vehicle; a spring 5 is pr...

Abstract

The invention discloses a hatchback door limiting device. The hatchback door limiting device comprises a limiting block and a limiting seat, wherein the limiting block is arranged on an inner board of a hatchback door, and the limiting seat is arranged on a side wall. The limiting seat is provided with a sliding block which is matched with the limiting block and slides in the limiting seat, and a spring is arranged between the sliding block and the limiting seat. The hatchback door limiting device can restrain vertical and horizontal shake and swing of the hatchback door to the maximum degree during driving of a car, effectively limit the hatchback door, improve the durability and reliability of the car door, estimate abnormal sound generated by shake of the hatchback door and improve NVH performance of the car; in addition, the spring is arranged between the sliding block and the limiting seat, the phenomenon that X-direction shift of the hatchback door is sharp when the hatchback door is closed or when the car drives can be effectively avoided, the durability and reliability of the car door are further improved, and the NVH performance and the reliability of the whole car can be improved.

Description

technical field [0001] The invention relates to a rear door structure of a rear lift type rear cover vehicle, in particular to a rear door position-limiting structure. Background technique [0002] Due to the particularity of the rear liftback model, the rear door is only restricted by the upper hinge of the door and the lower door lock, which is highly dependent on the rigidity of the body frame. When the rigidity of the body frame is relatively low, the rear liftgate is prone to local cracking in the dynamic road test and abnormal noise caused by shaking on gravel roads, which affects the durability and reliability of the rear liftgate and the NVH performance of the vehicle. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a rear door position-limiting structure that can improve the durability and reliability of the rear door and improve the NVH performance of the whole vehicle. [0004]...
