Description

Technical Field

[0001] The utility model belongs to the technical field of automobile part packaging, and particularly relates to a spacing packaging and positioning device for an automobile rear door. Background Art

[0002] An automobile rear door, usually called a trunk lid or a tailgate, is an openable lid installed at the rear of a vehicle to protect the luggage and goods in the vehicle. The automobile rear door is usually made of metal or other strong materials to withstand various loads in daily use. Its main functions also include protecting privacy and improving safety. After being manufactured by a factory, the automobile rear door needs to be transported to an automobile assembly workshop and the main frame of the automobile for assembly. During this process, a specific device is required to package it.

[0003] A Chinese patent with the publication number of CN219728881U discloses a transfer structure for a door and trunk to prevent bumping, including a bottom plate. A wrapping member for clamping the door and trunk is installed on the top of the bottom plate. The wrapping member is composed of a left wrapping block and a right wrapping block. Accommodating grooves adapted to the door and trunk are formed at the top end and one side of the left wrapping block and the right wrapping block. The above solution can protect the door and trunk during the transfer process when it shakes by clamping the trunk body in the accommodating groove of the wrapping member.

[0004] An automobile rear door usually consists of two structural surfaces as shown in the appendix Figure 1 Among them, the first structural surface is arc-shaped, and the second structural surface is fan-shaped. When the above solution is used, multiple automobile rear doors are arranged at intervals vertically, and the interval between adjacent automobile rear doors is relatively large, resulting in low utilization efficiency of space. Summary of the Utility Model

[0005] The utility model aims to provide a spacing packaging and positioning device for an automobile rear door to solve the problem of low utilization efficiency of space existing in the above solution.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automobile rear door spacing packaging positioning device includes a bottom plate. Multiple groups of clamping mechanisms are arranged in sequence on the top of the bottom plate. Each group of clamping mechanisms includes two symmetrically arranged clamping components. Each clamping component includes two centrally symmetric clamping units. Each of the clamping units respectively includes a first limiting block, a second limiting block, and a third limiting block. The first limiting block is L-shaped, and the two first limiting blocks of each clamping component are connected head to tail and enclose an installation groove.
