Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance auxiliary equipment, in particular to an auxiliary lying board for automobile underbody maintenance. Background Technique

[0002] When maintaining the underbody of an automobile, in order to facilitate the maintenance of the underbody, the staff need to lie on a lying board and slide to the underbody by relying on the casters at the bottom of the lying board. Most of the existing lying boards have a single structure. During the process of maintaining the underbody of the vehicle, it is inevitable to maintain positions at different heights from the ground at the bottom of the vehicle. When the height of the headrest cannot be adjusted, the user needs to lift the head to facilitate observing the maintenance position at close range. The long-term head-lifting action will make the user's neck feel uncomfortable, and the lying board is not convenient to use. Content of the Utility Model

[0003] The purpose of the utility model is to provide an auxiliary lying board for automobile underbody maintenance, so as to solve the technical problem of the inability to adjust the height when maintaining positions at different heights from the ground at the bottom of the vehicle by using the existing lying board as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An auxiliary lying board for automobile underbody maintenance, including a lying board body. A number of through holes are equidistantly penetrated through the concave part of the lying board body. A travel groove is opened at one end of the lying board body, and a through groove is penetrated through the inner bottom of the travel groove. A headrest and a electro-hydraulic push rod are respectively hinged in the travel groove and the through groove through a first pin shaft and a second pin shaft. A hinge seat is fixedly connected to the bottom of the headrest away from the first pin shaft, and the hinge seat is hinged to the telescopic end of the electro-hydraulic push rod.

[0005] As a preferred solution of the utility model, a number of universal wheels are symmetrically arranged at equal intervals at the bottom of the lying board body.

[0006] As a preferred solution of the utility model, two tool grooves are symmetrically opened at the top of the lying board body.

[0007] As a preferred solution of the utility model, an arm span groove is penetrated through the side wall at the top of the lying board body.

[0008] As a preferred solution of the utility model, grooves are opened on the outer walls on both sides of the lying board body, and a storage battery is arranged inside the grooves. The storage battery is electrically connected to the electro-hydraulic push rod.

[0009] Compared with the prior art, the beneficial effects of a maintenance auxiliary reclining board for the bottom of an automobile of the present utility model are as follows: The structure of the present utility model is simple and convenient to use. The headrest is hinged in the travel groove on the board body of the reclining board through the first pin shaft, so that when the electro-hydraulic push rod starts, it can drive the headrest to adjust the angle. After the headrest tilts and flips upwards, the head of the user can tilt upwards accordingly, enabling the neck of the user to be supported and effectively reducing the discomfort of the user's neck.
