Vehicle door anti-pinch control valve and pressure-sensitive anti-pinch door opening control system

Abstract

The invention provides a vehicle door anti-pinch control valve and a pressure-sensitive anti-pinch door opening control system. The anti-pinch control valve comprises a valve body and a central valve cavity formed in the valve body, wherein a valve rod is movably arranged in the central valve cavity; a magnetic induction switch is fixedly arranged on the left side of the valve body, a normally-open pressure sensor is fixedly arranged on the right side of the valve body, and a first spring is arranged between the right end of the valve rod and the right wall of the valve body; and an instantaneous exhaust channel leading to a switch cavity from the outside of the valve body is formed in the left end of the valve body, a main electromagnetic switch is fixedly arranged on the upper side of the left end of the valve body, a speed-regulating throttling connector is fixedly arranged on the upper side of the right end of the valve body, an air inlet connector is fixedly arranged on the lower side of the right end of the valve body, an air storage cavity is formed in the lower portion of the left end of the valve body in the left-right direction, the right end of the air storage cavity is communicated with an air inlet cavity through a second channel, and the left end of the air storage cavity is communicated with the left end of the central valve cavity through a third channel. When a vehicle door of a passenger car or a bus is about to be closed in place and people are pinched, the anti-pinch effect can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of car door control, in particular to a car door anti-pinch control valve and a pressure-sensitive anti-pinch door opening control system. Background technique [0002] The doors of passenger cars and buses are the only passages for passengers to get on and off the bus. Passengers will stay at the door when the vehicle is driving or parking. device. The existing anti-pinch devices are divided into airbag anti-pinch, delay anti-pinch and pressure sensor anti-pinch, but no matter which type of anti-pinch, there are disadvantages. When the door is about to close in place, if an object is caught, the anti-pinch will fail, which cannot meet the current situation. There is a passenger car standard (when clamping to a force measuring rod with a variable diameter of 30-60mm, the anti-clamping must be activated to open the door). There is a blind area in the existing anti-pinch system of passenger cars. If a person...

Problems solved by technology

The existing anti-pinch devices are divided into airbag anti-pinch, delay anti-pinch and pressure sensor anti-pinch, but no matter which type of anti-pinch, there are disadvantages. When the door is about to close in place, if an object is caught, the anti-pinch will fail, which cannot meet the current situation. There are passenger car standards (when clamping to a force measuring rod with a variable diameter of 30-60mm, the anti-clamping must be activated to open the door)

There is a blind spot in the existing anti-trap system of passenger cars. If a person is caught in the blind spot and the door cannot be opened, it will cause a safety problem that the passenger will be trapped.
