Description

Technical Field

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

[0002] With the continuous innovation and intelligent trend of automobile design, hidden door handles, as a novel and practical design element, have gradually been used in modern automobiles. This design not only improves the streamlined and overall beauty of the car's appearance, but also effectively reduces wind resistance and improves the vehicle's energy efficiency. However, hidden door handles still face challenges in ensuring safety performance.

[0003] Traditional hidden door handles are usually opened and closed by simple electric mechanisms, but such systems often lack intelligent obstacle detection functions. When there are obstacles near the door, such as the user's hands or other objects, the door handles may clamp these obstacles during the closing process, posing a safety hazard.

[0004] At present, some hidden door handles have adopted sensor detection technology in order to realize intelligent obstacle detection function. However, these sensors often have problems such as inaccuracy, insensitivity and low recognition accuracy in actual applications. This may cause the door handle to fail to detect obstacles in time during the closing process, thereby pinching the user's hands or other objects, and there is still a safety hazard.

[0005] Based on this, the applicant proposed an intelligent anti-pinch door handle to solve the above technical problems. Summary of the invention

[0008] Preferably, the drive comprises an electronic push rod or a worm gear motor or a cylinder.

[0009] Preferably, an alarm is also provided in the door handle body, an electrode sheet C is provided at one end of the slide slot near the alarm and connected to the alarm, a metal contact C is provided on the two-way connection switch to cooperate with the electrode sheet C, and the metal contact A is connected to the metal contact C.

[0010] Preferably, the alarm device includes a vibrator, a warning light or a buzzer.

[0011] Preferably, after the support rod is matched with the two-way connection switch, an integrated insulating and waterproof layer is coated on the outside.

[0012] The beneficial effects of the present invention are as follows: by setting a two-way connection switch, the function of the door handle automatically stopping closing when encountering an obstacle is realized, effectively avoiding the situation of pinching the user's hands or other objects, and greatly improving the safety of use; the device can identify obstacles more accurately and sensitively through a mechanical anti-pinch structure, which not only improves the reliability of the system, but also further enhances the user experience; an alarm is set, which can promptly send out an alarm signal when encountering an obstacle to alert the user. This design not only enhances the safety of the system, but also allows users to use hidden door handles more confidently. BRIEF DESCRIPTION OF THE DRAWINGS
