Adjustable automobile back door limiting opening assistor

Abstract

The invention provides an adjustable automobile back door limiting opening assistor. The adjustable automobile back door limiting opening assistor comprises a support, a push rod, an end cover, a spring, a sliding nut, a waterproof gasket and a buffer block. The push rod is located in the support. The buffer block is screwed at the outer end of the push rod. The end cover is arranged at an openingof the support. The outer edge of the opening of the support is sleeved with the waterproof gasket. The sliding nut and the spring are arranged between the support and the push rod. Convex ribs of the sliding nut are located in first grooves of the inner wall of the support. Convex points of the sliding nut are located in second grooves of the push rod. Convex points of the end face of the end cover are located in third grooves of the end face of the support. Through arrangement of the sliding nut, the problem the opening and closing force of a back door cannot be adjusted is effectively solved. The push rod is in thread fit with the buffer block. The problem existing in adjustment of the segment gap of the back door is solved. Through cooperation of the convex ribs and the grooves between the sliding nut and the support, adjustment and cooperation of the convex points and the grooves between the nut and the push rod and convex-concave cooperation between the adjoining planes of the end cover and the support, the anti-loose problem is solved in a small structure space.

Description

technical field [0001] The present invention relates to an adjustable automobile back door limit opening aid, which is a mechanism integrating back door limit and jacking functions which can adjust the limit height and pop-up force in a small range, and improves the position limit assist function. The adaptability of opening function. Background technique [0002] Most of the existing back door limit blocks are of fixed structure or simple spiral structure. The fixed limit block cannot adjust the limit height. Although the simple spiral limit block can realize limit adjustment, it does not jack up the back door. Function, for the rear door models that do not have an opening handle and are non-electrically opened and closed due to the shape of the rear door, there is insufficient space for the operation of the rear door after unlocking, which is not convenient for users to use. [0003] The jacking force of the existing jacking mechanism for opening the back door is not adju...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects in the prior art that the function of the limit block and the jacking mechanism of the back door is single, the number of parts is large when used together, the cost of parts and manufacturing is high, and the defect of low adaptability caused by the non-adjustable force value of the jacking mechanism, the present invention Provide a limit assist device that can simultaneously realize the height-adjustable limit function and the force value-adjustable back door opening assist function
