AI Technical Summary
The existing internally rotating back door hinges are easily interfered with the back door and the top cover under the complex roof shape, and cannot meet the hinge layout requirements of complex shapes.
The external rotating back door hinge structure is adopted, and the hinge axis is at the front end of the back door split joint. When the back door is opened, the door is opened outside or above the car, so that the gap between the back door and the top cover becomes larger and larger, which is complex to adapt to Hinge arrangement for top cover shape.
Under the complex roof shape, the safe movement gap between the back door and the roof is achieved, which increases the room for stylists to play in the car styling style.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile design and manufacture, and more specifically, to an outward-swinging back door hinge structure. Background Art
[0002] In the prior art, the back door hinges are mostly inward-turning hinges. When the back door is opened, the door moves toward the inside of the car, and the gap between the door and the top cover will become smaller and smaller. To ensure a safe movement gap, the top cover must be as flat as possible, with a large curved surface and no complex features. With the advancement of technology, autonomous vehicles are increasingly favored by car companies and consumers. The higher the degree of autonomous driving, the more problems are caused by the increasing number of detection radars with various functions installed on the car, and the roof is a disaster area for radar installation. In order to avoid the abrupt shape of the radar, it has become a trend to add complex decorations to the roof. However, in the inward-turning back door hinges of the prior art, the door moves toward the inside of the car during the door opening process, and the gap between the door and the top cover becomes smaller and smaller. When encountering an unmanned vehicle with a complex roof, the inward-turning hinge will cause the risk of interference with the top cover during the back door opening process. Therefore, the inward-turning back door hinge is not suitable for complex shapes. Utility Model Content

[0022] Example 1
[0023] like Figure 1-3As shown, the outward-swinging tailgate hinge structure of this embodiment includes a hinge fixing seat 10 and a hinge movable seat 30. In this embodiment, the hinge fixing seat and the hinge movable seat are steel hinge fixing seats and steel hinge movable seats, which are formed by a casting process. The hinge fixing seat 10 includes a body fixing plate 11, and three mounting holes 13 are processed on the body fixing plate 11, which are used to mount the body fixing plate 11 to the body sheet metal through fasteners. A hinge fixing arm 12 is provided on the body fixing plate 11, and a limiting protrusion 15 is provided on the upper end of the hinge fixing arm 12, and an intermediate shaft hole 14 is provided on the hinge fixing arm 12. The hinge movable seat 30 includes a tailgate fixing plate 31, and two mounting holes 36 are processed on the tailgate fixing plate 31, which are used to mount the tailgate fixing plate 31 to the tailgate through fasteners. The back door fixing plate 31 is provided with a rotating arm 35, which is an L-shaped structure, and a limiting plane 33 is provided at the end of the rotating arm 35, and two connecting arms 32 are provided on both sides of the end of the rotating arm 35, and an end shaft hole 34 is provided on the connecting arm 32. The hinge fixing arm 12 is arranged between the two connecting arms 32 and connected by a pin 40 passing through the end shaft hole 34 and the middle shaft hole 14, and a bushing 20 is provided in the end shaft hole 34. A waterproof gasket 50 is provided on the vehicle body fixing plate 11. When the hinge movable seat 30 rotates to the limiting state, the limiting protrusion 15 contacts the limiting plane 33 and realizes the limiting function.
[0024] In this embodiment, as an example, the bushing can be made of steel-based copper mesh polytetrafluoroethylene; the waterproof gasket is made of PNG-8100 material with a thickness of 1.0 mm, which is used to ensure the sealing of the body end sheet metal of the tailgate hinge.
[0025] This embodiment uses an outward-swinging tailgate hinge, with the hinge axis at the front end of the tailgate split. When the tailgate is opened, the door opens to the outside or above the car, so the gap between the tailgate and the top cover becomes larger and larger, which is very conducive to the hinge arrangement of complex top cover shapes. The minimum gap between the top cover and the tailgate is usually in the closed position, and the gap between the tailgate and the top cover at the maximum opening position should also be paid attention to. When in the closed state, ensure that the safety gap between the tailgate and the top cover meets the requirements; when in the maximum opening state, add a self-limiting structure (such as Figure 4-5 As shown in the figure, it is sufficient to ensure a safe gap between the back door and the top cover when the hinge is in the limit position.
[0026] The outward-swinging tailgate hinge structure of this embodiment can be used for models with complex decorative cover structures on the top cover. Figure 6As shown, the top of the vehicle body is a roof decorative cover, the outward-swinging tailgate hinge is hidden under the roof decorative cover and screwed to the vehicle body, and there is a spoiler structure with a complex shape above the tailgate. When the door is opened, the tailgate and the spoiler move upward, and the gap with the top cover becomes larger and larger. When ordinary inward-swinging hinges are applied to this shape, the tailgate will interfere with the top decorative cover during opening, while the outward-swinging tailgate hinge can realize the structural design of this shape. The outward-swinging tailgate hinge structure of this embodiment can better adapt to the hinge arrangement of the complex top cover shape of the unmanned vehicle, so that the engineering design has fewer restrictions on the shape, and the stylist has more room to play in the car styling style.
