Description

Technical Field

[0001] The utility model relates to the technical field of auto parts devices, in particular to an anti-collision structure of an automobile scissor door. Background Art

[0002] With the advancement of automobile technology, the appearance of cars is constantly being updated and iterated, becoming more and more fashionable and high-end. For example, the application of scissor doors makes the appearance of cars more attractive and high-end. Regarding the opening of the scissor doors of cars, it generally includes two processes; specifically, the first is to separate the scissor doors from the car body by swinging them outward, and the second is to rotate them upward to complete the opening of the car door. Similarly, when closing the car door, the scissor door first rotates downward, then swings inward, and finally completes the closing of the car door. However, in the process of closing the scissor door, human operational errors are prone to occur. When the scissor door has not rotated downward or has not rotated to the specified position, pressing the scissor door inward to cause it to swing inward can easily cause damage to the hinge structure of the scissor door or the scissor door, resulting in unnecessary maintenance costs. Therefore, it is necessary to propose a structure to prevent the scissor door from swinging inward due to accidental operation, so as to improve the safety performance of the scissor door.

[0003] A search revealed a Chinese patent document [Application Number: CN202122409870.2] for an automotive scissor door anti-collision structure. This structure includes a blocking anti-collision member and a collision isolation member. The blocking anti-collision member is connected to the frame of the scissor door hinge, and the collision isolation member is mounted on the door connector of the scissor door hinge, extending inward. When the scissor door has completed its outward swing, the collision isolation member remains outside the blocking anti-collision member, and the collision isolation member is positioned opposite the blocking anti-collision member.

[0004] The structure disclosed in this patent can effectively limit the position of the inward swinging movement of the automobile scissor door, so as to reduce the damage caused by the automobile scissor door swinging in an incorrect position. However, when the structure is in use, the impact caused by the direct contact between the collision isolation part and the blocking limit block will cause damage to the blocking limit block and the connecting block. When the blocking limit block and the connecting block are damaged, it is easy to affect the subsequent use effect of this structure. Since the positions of the blocking limit block and the connecting block in this structure are relatively stable, it is inconvenient for the staff to quickly replace the blocking limit block and the connecting block, which is easy to affect the subsequent use of the structure.

[0025] The auxiliary mechanism 8 includes a slide plate 81, an extension plate 82 and a compression spring 83. The surface of the slide plate 81 is slidably connected to the inner wall of the hollow frame 7, and the extension plate 82 slides through the surface of the hollow frame 7. The extension plate 82 is fixedly connected to the surface of the slide plate 81. The compression spring 83 is arranged inside the hollow frame 7. The two ends of the compression spring 83 are fixedly connected to the inner wall of the hollow frame 7 and the surface of the slide plate 81 respectively. The force-bearing plate 10 is fixedly connected to the surface of the extension plate 82. When the force-bearing plate 10 is subjected to force, it can drive the extension plate 82 to move. At this time, the slide plate 81 moves accordingly. The piston rod of the micro damper 9 is fixedly connected to the surface of the slide plate 81. During the movement of the slide plate 81, the micro damper 9 and the compression spring 83 can cooperate to buffer the movement of the slide plate 81 to reduce the hard contact between the connecting ball 3 and the groove 11. The surface of one side of the force-bearing plate 10 is designed to be arc-shaped. The thickness of the force-bearing plate 10 is less than the length of the extension plate 82. Accordingly, the practicality of the force-bearing plate 10 can be increased and the movement of the extension plate 82 can be guaranteed.

[0026] The limiting mechanism 14 includes a vertical plate 141, a connecting plate 142 and a limiting frame 143. There are two vertical plates 141.

The size of the limiting frame 143 is equal to that of the card frame 4. The number of the limiting frame 143 and the card frame 4 is several, and the adjacent The two limit frames 143 are symmetrically arranged with the card frame 4. By cooperating with the limit frames 143 and the card frame 4, the card block 6 can be limited, and the position of the hollow frame 7 can be fixed accordingly. The fixing plate 15 is fixedly connected to the top of the connecting plate 142. The surface of the door hinge frame 1 is fixedly connected with a rectangular block 12, and the top of the rectangular block 12 is fixedly connected with a positioning rod 13. The vertical plate 141 is slidably mounted on the surface of the positioning rod 13. The cooperation of the rectangular block 12 and the positioning rod 13 can increase the stability of the vertical plate 141.

[0027] Working principle: When the door connector 2 is under force, the connecting ball 3 contacts the inside of the groove 11 and pushes the force-bearing plate 10. At this time, the extension plate 82 is forced to drive the slide plate 81 to move, and the micro damper 9 and the compression spring 83 cooperate to cushion the movement of the slide plate 81 to reduce the possibility of damage to the force-bearing plate 10 and the extension plate 82. When the impact force of the door connector 2 on the force-bearing plate 10 is large, and the auxiliary mechanism 8, micro damper 9 or the force-bearing plate 10 is damaged, the staff can first release the contact between the positioning bolt and the door hinge frame 1, and then remove the vertical plate 141 by pulling the connecting plate 142 to release the limit frame 143 on the block 6. After that, the staff can pull the hollow frame 7 to remove the auxiliary mechanism 8. Based on this, the staff can replace the force-bearing plate 10, the auxiliary mechanism 8 and the micro damper 9 at the same time to ensure the subsequent use effect of this structure.
