Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an intelligent anti-pinch trunk lid. Background Art

[0002] With the rapid development of the automotive industry and consumers' increasing demands for automobile safety and intelligence, the design of car trunk lids has gradually become more intelligent and user-friendly. When closing a traditional trunk lid, if there are obstacles (such as fingers, pets, etc.), it may cause pinching injuries, causing inconvenience and safety hazards to users. Therefore, it is particularly important to develop an intelligent trunk lid with anti-pinch function.

[0003] Existing anti-pinch technology mostly uses sensors to detect obstacles, but this method has problems such as high false alarm rate, high cost and complex installation. The sensor detection failure rate of some vehicles is high, resulting in the anti-pinch function being "dead in name only". Therefore, the market urgently needs an intelligent anti-pinch trunk lid with a simple structure, low cost and the ability to effectively prevent pinching injuries.

When the trunk lid main body 1 is closed, the sealing cover 2 opens to expose the anti-pinch block 4. When there is an obstacle under the anti-pinch block 4, the obstacle lifts up the anti-pinch block 4, and the anti-pinch block 4 slides to the metal contact 7 and contacts the electrode pair 5, and is connected to the warning circuit, so that the warning light 6 lights up and transmits a signal to the vehicle control system. The vehicle control system controls the trunk lid main body 1 to pause closing and prevents the sealing cover 2 from closing.

[0035] Preferably, several through holes are provided on the fixed plate 3 corresponding to the anti-pinch block 4, and a guide column 8 is provided on the upper side of the anti-pinch block 4, and the guide column 8 is adapted to the through hole. A limit block 9 is fixedly installed on the upper side of the guide column 8, and a spring 10 is provided between the limit block 9 and the fixed plate 3.

[0036] Preferably, the metal contacts 7 are arranged on both sides of the limit block 9 . When there are no obstacles, the anti-pinch block 4 is in the initial position, and the electrode pair 5 is located above the metal contacts 7 and does not contact the metal contacts 7 .
