Abstract
The utility model relates to limit devices of a vehicle door, in particular to a hand-protected device of the vehicle door. The hand-protected device of the vehicle door is characterized in that a storage battery is connected with a circuit control normally-closed switch which is connected with an electromagnet I; the electromagnet I and an electromagnet II are connected to a circuit in a reverse direction mode, and the same magnetic poles of the electromagnet I and the electromagnet II are adjacent; the electromagnets are connected with a thermal sensitive resistor which is connected to the storage battery. When the hands of a driver or passengers or other parts of the body touch the vehicle door and are clamped possibly, the temperature of the thermal sensitive resistor is increased and the resistance value of the thermal sensitive resistor is decreased, a current of the whole circuit is increased, a current in a coil winding the electromagnets is increased, the magnetism of the electromagnets is strengthened, the repulsive force of the two electromagnets is increased, the movement direction of the vehicle door can be changed rapidly, and the vehicle door stops closing or is forced to be opened.
Description
Technical field
The utility model relates to the inhibiting device of arrangements for automotive doors, especially about a kind of finger pinch device of arrangements for automotive doors.
Background technology
Have mechanism investigation to show: the occurrence probability that is crushed by car door also often has the various disputes that caused by the car door hand clamping up to 10% on newspaper, the TV news.This shows, the car door finger pinch device has been installed after, driver and crew's safety then can improve greatly.Such car door finger pinch device also can be installed on the bus simultaneously, reduces the occurrence probability that the passenger is crushed by car door.
Summary of the invention
The purpose of this utility model is to solve the problem that prevents the car door tong, provides a kind of automobile to close the door in the process and guarantee the device of driver and crew's health safety when driver and crew's finger or other body parts may be clipped to.Be achieved through the following technical solutions:
The utility model car door finger pinch device comprises storage battery, circuit control normally closed switch, electromagnet I, electromagnet II, thermally dependent resistor, and described storage battery links to each other with circuit control normally closed switch; Circuit control normally closed switch links to each other with electromagnet I; Electromagnet I and the reverse incircuit of electromagnet II make its magnetic pole of the same name adjacent; Described electromagnet links to each other with thermally dependent resistor, and thermally dependent resistor is connected in storage battery.
Storage battery works to provide electric energy in whole system, be the energy supply equipment of whole system, and the electric current that storage battery provides and voltage swing need to the highlyest bear the suitable selection of voltage according to what wire the highest born electric current and electromagnet.
Electromagnet is the core work equipment of this car door finger pinch device, electromagnet I and electromagnet II adopt opposite coil winding mode, make its magnetic pole of the same name relative, two electromagnet provide under the condition of electric energy at storage battery, utilize electromagnetic induction principle to produce magnetic, magnetic pole of the same name is adjacent, therefore two electromagnet repel mutually, thereby the obstruction closing of the door plays the effect that prevents the car door tong.
The effect of thermally dependent resistor is the whole circuit of control, when driver and crew's hand or other body parts touch car door and may be clipped to, resistance descends thereby thermally dependent resistor is experienced the temperature rising, the electric current of whole circuit increases, be wrapped in electric current increase in the coil on the electromagnet, the electromagnet magnetic enhancement, two electromagnet repulsive forces increase, can change rapidly the sense of motion of car door, make the car door phase down or force it to open; When driver and crew's hand or other body parts do not touch car door, do not affect at closing time, because the thermally dependent resistor resistance is larger, twine in the magnet spool electric current less, almost can ignore, so do not affect normally closing of car door.
Circuit control normally closed switch is being controlled the break-make of whole circuit, when ambient temperature is very high, possible driver and crew's hand or other body parts do not touch car door, the resistance of thermally dependent resistor diminishes because ambient temperature is too high, the difficult that will become of at this moment closing the door, at this moment, open circuit control normally closed switch, whole circuit disconnects, behind the entrance door of pass, and circuit control normally closed switch auto-closing.
Advantage of the present utility model:
When the arrangements for automotive doors accident that 1, has solved existing hinge arrangement was closed, the problem that tong brings potential safety hazard easily occured.
2, the utility model structure is very simple, is installed in to take up room littlely in the car, and convenient to the car door transformation of existing engineering truck, safe reliability is high, can effectively avoid the generation of safety misadventure.
3, be not only applicable to engineering truck, exist the door of above-mentioned potential safety hazard all applicable for various employing chain connections.
Description of drawings
Fig. 1 is the electrical block diagram of the utility model car door finger pinch device.
The specific embodiment
The 1-storage battery; 2-circuit control normally closed switch; 3-electromagnet I; 4-electromagnet II; The 5-thermally dependent resistor.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model car door finger pinch device comprises storage battery 1, circuit control normally closed switch 2; Electromagnet I3; Electromagnet II4; Thermally dependent resistor 5 etc.; When driver and crew's hand or other body parts touch car door and may be clipped to, resistance descends thereby thermally dependent resistor is experienced the temperature rising, the electric current of whole circuit increases, be wrapped in electric current increase in the coil on the electromagnet, the electromagnet magnetic enhancement, two electromagnet repulsive forces increase, and can change rapidly the sense of motion of car door, make the car door phase down or force it to open; When driver and crew's hand or other body parts do not touch car door, do not affect at closing time, because the thermally dependent resistor resistance is larger, twine in the magnet spool electric current less, almost can ignore, so do not affect normally closing of car door; When ambient temperature is very high, possible driver and crew's hand or other body parts do not touch car door, the resistance of thermally dependent resistor diminishes because ambient temperature is too high, at this moment the difficult that to become of closing the door, at this moment, open circuit control normally closed switch, whole circuit disconnects, after closing entrance door, circuit control normally closed switch auto-closing.
