Anti-pinch door, anti-pinch door sealing strip and vehicle using anti-pinch door

Abstract

The invention provides an anti-pinch door, an anti-pinch door sealing strip and a vehicle using anti-pinch door, relating to the bus industry and having good anti-pinch effect. The anti-pinch door comprises a door body, and a sealing strip for sealing is arranged on the side of the door body, wherein an optical signal channel is provided, and an optical signal transmitter and a receiver are respectively disposed at two ends thereof; the portion of the sealing strip on the side of the optical signal channel facing away from the door body is a wedge-shaped portion whose cross-section gradually increases from one side, and the wedge-shaped structure is offset from the optical signal channel to be outwardly folded and deformed when blocked; the sealing of the door is realized by folding the wedge portion of the sealing strip outward, and the process does not cause a large deformation of the optical signal channel to block the transmission of the optical signal, thereby ensuring the sealingproperty. If an object is mistakenly caught by the door, the sealing strip will be further deformed to deform the optical signal channel, thereby blocking the transmission of the optical signal and opening the door. While ensuring normal sealing, it can ensure the correct judgment of the anti-missing clip and improve the reliability.

Description

technical field [0001] The invention relates to the passenger car industry, in particular to an anti-pinch car door. Background technique [0002] With the development of economy and technology, the population continues to increase, and the large-scale use of fossil fuels has led to energy crisis and environmental pollution. In the process of using a car, safety is always the most concerned issue of the public. Bus door "biting" incidents occur frequently, so it is more and more important to have a complete anti-pinch system. However, the anti-pinch technology of bus doors in the existing technology is still the technology of five years ago, which cannot meet people's consumption needs. More importantly, the anti-trapping of the car door involves the personal safety of passengers, especially for some elderly and child passengers.

AI Technical Summary

Problems solved by technology

However, the problem with this structure is that the sensor will sense when the door is clamped to the passenger, and the cylinder needs to be subjected to a large force. Control, if the anti-pinch force threshold is set too small, the vehicle body will vibrate when the bus goes uphill, and the cylinder push rod in the air pressure sensor will vibrate, which will cause the sensor to generate an error signal, and the control system will automatically open the door, making driving unsafe

Since the arrangement of the left and right sealing strips is a centrally symmetrical structure, each door has a corresponding door passage, and the doors are split. During subway driving, the airtightness of the doors must be ensured. If airtightness is required, it must be improved. At this time, if the pressure is too high, the sealing rubber strip will be deformed, which will affect the transmission of the light signal, and increase the probability of the door being opened by mistake. safety hazard

On the contrary, if you want to ensure the safety of passengers, you must ensure the sensitivity of anti-pinch, which will reduce the pressure of closing the door and reduce the airtightness of the compartment.
