Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door hinges, in particular to a vehicle door limiting hinge with a built-in shock-absorbing function. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Hinges can be made of movable components or foldable materials. Hinges are often installed on cabinets and are categorized by material into stainless steel and iron hinges. To provide greater comfort, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is that they provide a cushioning effect when the door closes, minimizing the noise caused by the door colliding with the cabinet body.

[0003] After searching, a Chinese patent with publication number CN218438857U discloses a limited door hinge, the technical points of which are: it includes a hinge seat connected to the car, a movable hinge connected to the door, a rotating device connecting the hinge seat and the movable hinge, and a limiting device for limiting the rotation of the movable hinge. A movable hinge is provided at the upper end of the hinge seat, and a rotating device is provided between one end of the hinge seat and the connecting end of the movable hinge, and a limiting device is provided between the hinge seat and the movable hinge. The limited door hinge uses the gear on the limiting device to rotate the chain, so that the limiting block moves, thereby adjusting the distance of the limiting groove, so that the angle of opening of the door is changed, ensuring the safety of children in the car, preventing children from accidentally opening the door and causing danger, and using the limiting rod on the limiting device to move in the limiting groove, so that the door is restricted in the process of rotating and opening, thereby ensuring the safety of people.

[0004] The above solution solves the problem of inconvenience in adjusting the opening angle of the car door, but the above solution lacks a shock-absorbing mechanism, which is not convenient for buffering the impact force generated by closing the car door, accelerates the wear of the car door hinge, and reduces the service life of the car door hinge.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

When the second base 8 is in contact with the first base 1, the fixing clamp 7 and other components enter the interior of the groove 2, thereby achieving the effect of shock absorption and buffering of the impact force of closing the door.

[0027] See also Figure 1 、 5 Four first mounting holes 14 are provided on one side of the first base 1 corresponding to the second base 8, and four first mounting nails 15 are provided on one side of the first base 1. Each first mounting nail 15 corresponds to a first mounting hole 14, thereby realizing the installation and fixation of the first base 1 and the car body.

When the car door is closed, the car door drives the second base 8 to rotate, and the second base 8 drives the two limiting members 18 to rotate around the connecting rod 11, so that the position of the limiting rod 20 inside the limiting groove 19 changes. At the same time, the second base 8 drives the connecting member 9 to rotate around the connecting rod 11, so that the side of the second base 8 equipped with the fixing clip 7 is fitted with the side of the first base 1 with the groove 2, and the fixing clip 7 enters the inside of the groove 2. The second base 8 drives the damper 5 to contract through the fixing clip 7 and the rotating block 6, and the damper 5 drives the mounting block 3 to rotate inside the groove 2 through the support rod 4, thereby buffering and shock absorbing the impact force of closing the car door.
