Foldable automobile tailboard

Abstract

A fixed supporting plate and a movable supporting plate are connected through a rotating pair, the opening and closing degree of the fixed supporting plate and the opening and closing degree of the movable supporting plate are determined according to whether the loading and unloading environment is wide or not, and two or three corresponding bearing plates are unfolded; the three bearing plates can be folded to the fixed bearing plate, the space occupied by unfolding and folding is about half meter in the vertical direction, the sweeping space is small, and potential safety hazards are reduced.

Description

Technical Field

[0001] This invention patent relates to the field of vehicle tailgates. Background Art

[0002] When loading and unloading goods with relatively large volume or heavy weight, small and medium-sized trucks need to rely on loading and unloading tailgates to complete the operation. Currently, the common loading and unloading tailgates are mounted on the rear end of the carriage. When in use, they are lowered flat through a hydraulic structure, and after use, they are retracted to be vertically attached to the rear end of the carriage.

[0003] During the loading and unloading of goods, there are safety hazards during the process of the tailgate being retracted and lowered, and the spatial range swept by the tailgate is easily overlooked; it cannot be normally retracted and deployed in places with limited space. Summary of the Invention

[0004] The purpose of this invention patent is to provide a loading and unloading tailgate with relatively small safety hazards and good space adaptability.

[0005] To achieve the above purpose, the solution adopted in this invention patent is: two fixed support plates are installed on the vertical lifting system. The end of the fixed support plate forms a supporting rotating pair with the moving support plate through a thrust bearing and a deep groove ball bearing; the fixed support plate is connected to the fixed bearing plate by bolts. The fixed bearing plate forms a rotatable connection with the moving bearing plate through a connecting plate. The moving bearing plates are also connected by a connecting plate. There is a square hole in the middle of the connecting plate connected to a mandrel, and the mandrel is installed on the side of the moving bearing plate through a bearing.

[0006] The bearing plate in this invention patent consists of three sections and can be adjusted according to the size of the loading and unloading site space; the retraction and deployment of the tailgate are almost completed within a space of half a meter up and down, with a small swept space, and it must be operated by a dedicated person, which can prevent neglect of the surrounding environment.

[0010] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0011] Embodiment

[0012] As Figure 1 、 Figure 2As shown in the figure, the present invention includes: a fixed bearing plate 2, a moving bearing plate 3, a bearing 4, a connecting plate 5, a nut 6, a moving bearing plate 7, a mandrel 8, a moving support plate 9, a thrust bearing 10, a deep groove ball bearing 11, a fixed support plate 12, and a bolt 13. The fixed support plate 12 is installed on the vertical lifting mechanism 1 to realize the rise and fall of the entire tail plate. The end of the fixed support plate 12 forms a rotatable pair with a supporting function with the moving support plate 9 through the thrust bearing 10 and the deep groove ball bearing 11. The moving support plate 9 can determine the opening and closing degree according to whether it needs to support two or three bearing plates. The fixed bearing plate 2 is connected to the fixed support plate 12 through the bolt 13. The fixed bearing plate 2 and the moving bearing plate 3 are connected through the connecting plate 5. There is a square hole in the middle of the connecting plate to connect with the mandrel 8. The nut 6 axially limits the connecting plate 5. The mandrel is connected to the side of the moving bearing plate 3 through the bearing 4. The centers of the connecting plate 5 and the mandrel 8 are concentric with the semi-circular cross-section of the moving bearing plate 3, so that the bearing plates are closely connected when folded up or unfolded.

[0013] The usage process of the present invention is as follows: When arriving at the loading and unloading location, start to unfold the loading and unloading tail plate. First, unfold the moving support plate 9. If the loading and unloading environment is spacious, both of the two moving support plates 9 on both sides can be rotated by 90°. If the loading and unloading environment is narrow, both of the two moving support plates 9 on both sides can be rotated by 45°. Then start to unfold the bearing plates. Flip the moving bearing plate 7 outwards. Due to the connection function of the connecting plate 5, the moving bearing plate 3 will be unfolded accordingly. The three bearing plates are laid flat for loading. If only two bearing plates are needed, then screw out the nut 6 and remove the connecting plate 5 to realize the separation of the moving bearing plates 3 and 7. The retracting process is the opposite process.
