Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to an adjustable damping structure of a vehicle door hinge. Background Art

[0002] The application of door hinge mechanism mainly includes the following aspects: Maintain the stability of the door: The door hinge mechanism can ensure that the door remains stable during driving and will not be accidentally opened or closed. It connects the car body and the door through a hinge, so that the door can be opened and closed within a certain angle and remain stable in the open or closed state. Provide opening and closing functions: The door hinge mechanism allows the door to be opened and closed when needed. By rotating the hinge, the door can be rotated from a closed state to an open state, or from an open state to a closed state, which makes it easy for passengers to enter and exit the vehicle. Adjust the opening angle of the door: The door hinge mechanism usually has an adjustable feature that can control the opening angle of the door, which is very important for operations such as passengers getting on and off the vehicle, loading and unloading items, etc. By adjusting the position or angle of the hinge, different opening angles can be achieved to meet different usage requirements. Support the weight of the door: The door is usually heavy, so a door hinge mechanism is needed to support the weight of the door. A reasonably designed door hinge mechanism can share the weight of the door and balance the force distribution of the door through the structure of the hinge to ensure smooth movement of the door when opening and closing.

[0003] The existing equipment has low stability and supporting strength during use, which may cause the door to shake or sway during the opening or closing process, thereby increasing the risk of accidents. In particular, the sudden opening of the door during driving may cause harm to passengers in the car and pedestrians around. The low stability and supporting strength may cause premature wear or damage to the hinge parts, thereby shortening the service life of the door. Frequent repairs and replacements not only increase costs, but also affect the reliability and safety of the vehicle.

[0004] Therefore, there is an urgent need to provide an adjustable damping structure for a door hinge to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the above-mentioned prior art and provide an adjustable damping structure for a vehicle door hinge.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an adjustable damping structure of a door hinge, comprising a first mounting plate, a plurality of first bolts are threadedly connected to the front end of the first mounting plate, a first gasket is slidably connected to the outer wall of the plurality of first bolts, and two first connecting plates are fixedly connected to the front end of the outer wall of the first mounting plate;

[0012] The utility model is further configured as follows: one side of the outer wall of the two third rotating rods and the fourth rotating rod is rotatably connected to the outer wall of the corresponding connecting rod.

[0014] The utility model is further configured as follows: the top of the outer wall of the third rotating rod is tightly fitted with the corresponding surfaces of the outer walls of the first rotating rod, the second rotating rod and the second connecting plate.

[0015] Through the above technical solution, the stability of the structure can be enhanced and the connecting parts can be prevented from loosening or swinging during use, which helps to maintain the position and posture of the connecting parts stable and improve the reliability and durability of the overall structure.

[0016] The utility model is further configured as follows: the first mounting plate and the second mounting plate are both in an integrated structure with the corresponding first connecting plate and the second connecting plate.

[0020] The utility model is further configured as follows: a damping transmission assembly is installed on the top of the first mounting plate, and the damping transmission assembly includes a plurality of connecting blocks fixedly connected to the first mounting plate and the inner wall of the fourth rotating rod, a limiting rod is fixedly connected between the inner walls of every two of the connecting blocks, and a damper is rotatably connected between the outer walls of the two limiting rods.

[0021] Through the above technical solution, first, when the car door is opened, the damper will rotate along the two outer walls, thereby assisting the rotation of the hinge. When the car door is closed, the damper will shrink inward until the door is closed, thereby reducing the lateral pressure on the hinge during the rotation process and increasing the service life of the hinge.

[0022] The beneficial effects of the utility model are as follows:

[0023] 1. The utility model can provide stronger support and stability by setting a connecting rod assembly, because it is usually composed of multiple connected rods and can withstand greater force and pressure, which makes the connecting rod hinge more reliable and durable in applications with heavy loads;

The utility model provides a damping transmission assembly, and the installed damper can effectively assist the opening and closing of the vehicle door, and can also slow down the closing speed of the door, thereby protecting the door and the vehicle body and improving the safety of the door closing.
