Description

Technical Field

[0001] This utility model relates to the field of limit device technology, and in particular to an automotive hinge limit device with an alarm function. Background Technology

[0002] In automotive door systems, hinge limiters are crucial components ensuring the normal opening and closing of doors. They prevent excessive opening and closing from causing damage to the vehicle body or inconvenience by limiting the door's rotation angle. Existing limiters mostly rely on mechanical structures to achieve their limiting function, such as using cams, damping blocks, and other components to limit the door angle. However, these devices generally lack status monitoring and alarm functions.

[0003] In practical use, hinge limiters may experience component wear and lubrication failure due to prolonged high-frequency use, leading to jamming. External impacts can also cause installation position misalignment, resulting in abnormal door opening angles and reduced sealing performance. These potential faults may go undetected, potentially causing door noises, difficulty opening and closing, and even safety hazards such as accidental door opening while driving. Developing a hinge limiter with fault warning capabilities is crucial for improving vehicle safety and maintenance efficiency. Utility Model Content

[0012] Preferably, the buffer block is made of elastic rubber, and the pressure sensor is embedded in the center of the buffer block. The pressure sensor is electrically connected to the control module.

[0013] The beneficial effects of this utility model are as follows:
