Abstract
A hand-squeezing-preventing control system of an automobile door comprises an isolation diaphragm pressure sensor, a microprogrammed control unit (MCU), a spiral coil, a magnet and a relay switch. The isolation diaphragm pressure sensor inducts external pressure, the spiral coil is connected with the relay switch, and the MCU receives value signals of the isolation diaphragm pressure sensor and controls on and off of the relay switch according to pressure values. When the spiral coil is powered on, magnetic force of a magnetic field and magnetic force of the magnet are mutually exclusive, so that the automobile door can not be closed, and when the spiral coil is not powered on and has no repulsive force, the automobile door can be closed. The hand-squeezing-preventing control system aims to achieve the purpose that when fingers of a passenger are placed on a door frame, the automobile door can not be closed due to repulsive force.
Description
Technical field
The utility model relates to passenger the system field, the particularly anti-extrusion hand shift of a kind of arrangements for automotive doors system of guaranteeing.
Background technology
Present arrangements for automotive doors kind has a variety of, and topmost have two kinds: rotary car door and parallel-moving type car door.Rotary car door is widely used in all kinds of automobiles, and the parallel-moving type car door generally is applied to above the light bus.Be which class car door all exists a potential safety hazard, when closing under the car door effect in external force suddenly, if the passenger is ignorant and finger also is placed on the doorframe, the phenomenon that is easy to cause the passenger to point and crushes injury is so necessaryly install the anti-extrusion hand shift of a kind of car door system at automobile.
Summary of the invention
The purpose of this utility model is when passenger finger is placed on the doorframe, and car door can be subjected to a repulsive force and can't be closed.
The anti-extrusion hand shift of a kind of arrangements for automotive doors system comprises the isolation diaphragm pressure sensor, MCU control center, helicoil, magnet, relay switch.Isolation diaphragm pressure sensor induction ambient pressure, helicoil links to each other with relay switch, and MCU control center receives isolation diaphragm pressure sensor number signal and according to the switching of the big or small control relay switch of force value.Magnetic field magnetic force and the mutually exclusive car door that makes of magnet magnetic force can't be closed during the helicoil energising, do not have the repulsive force car door during helicoil no power and can close.
The utility model is the advantage of prior art relatively:
1. this system stops closing of the door for the repulsive force of magnet by the energising helicoil, avoids the passenger to point and is crushed.
2. this system all is suitable for for rotary car door and parallel-moving type car door.
Description of drawings
Fig. 1 is the anti-extrusion hand shift system architecture diagram of a kind of arrangements for automotive doors of the utility model
The specific embodiment
The isolation diaphragm pressure sensor that uses in the utility model is covered in the edge of doorframe.For rotary car door, magnet and helicoil are installed on respectively on car door and the vehicle body relative with car door, both be installed near the car door S. A. and the position relative; For the parallel-moving type car door, normally close in order not influence car door, magnet and helicoil should be embedded in car door and the doorframe respectively and the position relative.Set MCU control center, when its isolation diaphragm pressure sensor pressure signal value that receives hour, the control relay on off state be closure; When its isolation diaphragm pressure sensor pressure signal value that receives is zero or numerical value during more greatly much larger than finger pressure, the control relay on off state is for disconnecting.When passenger's finger is placed on the doorframe, the isolation diaphragm pressure sensor can be sensed pressure and the pressure signal value is sent to MCU control center, so because the less MCU of force value control center can make the relay switch closure helicoil energising produce magnetic field, magnetic force that magnet makes the magnetic field magnetic force of helicoil and magnet rationally is installed is repelled mutually and make car door to close.When passenger's finger be not placed on the doorframe or car door normally to close be that pressure signal value that the isolation diaphragm pressure sensor is sensed is zero or numerical value when big, MCU control center can disconnect relay switch and not produce repulsive force and makes car door to close.
Claims (1)
1. the anti-extrusion hand shift of arrangements for automotive doors system, comprise the isolation diaphragm pressure sensor, MCU control center, helicoil, magnet, relay switch, it is characterized in that: isolation diaphragm pressure sensor induction ambient pressure, helicoil links to each other with relay switch, MCU control center receives isolation diaphragm pressure sensor number signal and according to the switching of force value size control relay switch, magnetic field magnetic force and the mutually exclusive car door that makes of magnet magnetic force can't be closed during the helicoil energising, do not have the repulsive force car door during helicoil no power and can close.
