Embodiment Construction

[0018] In Fig. 1, Fig. 2 and Fig. 3, when opening the car door, the car door drives the car door support 6 to rotate, and the car door support 6 drives the rotating hinge pin 5 to rotate around the central axis of the hinge device through the anti-rotation parts at both ends of the rotating hinge pin. When the axial protrusion 5a of the hinge pin 5 is located in the annular groove 4a of the rubber 4, since the annular groove 4a of the rubber 4 acts as resistance to the axial protrusion 5a of the hinge pin 5, the automobile door system will remove the external force. After stopping at the current angular position, when the axial protrusion 5a of the hinge pin 5 is located in the middle of the annular protrusion 4c of the rubber 4, the rubber 4 is in the maximum deformation state at the annular protrusion 4c, and the energy absorbed by the rubber 4 reaches The maximum critical value, when a small external load is applied to the car door, the rubber 4 will release the energy, and ...

Description

technical field [0001] The present invention relates to an automobile door hinge, in particular to an automobile door hinge with a limiting function and a stopping function, wherein the limiting function can limit the limit opening angle of the automobile door, and the stopping function can make the automobile door operate at a predetermined force. Keep it at the predetermined opening angle position. Background technique [0002] The opening and closing of the car door is generally realized by a hinge device. The car door hinge is not only used to support the weight of the car door, but also to make the car door rotate around the hinge pin. However, ordinary car door hinges cannot limit the door to a specific angle, so that the convenience and safety of the people who use the car cannot be effectively guaranteed when entering and exiting the car. [0003] The most commonly used car door stop device uses a spring system and a cam device that rotates with the door to release ...
