When operating the elevating switch to make the car window rise, the corresponding state of the elevating sensing component and the fixed sensing component can be detected by the microprocessor as well as the load electric current of the motor so as to control the operation or reversion of the motor in good time, thus the safe efficacy of anti-entrapping can be realized.
Description
Technical field
The utility model relates to the safe anti-jamming device of motorized window in a kind of vehicle, be meant the lifting position and the state of utilization inductive component detecting vehicle window especially, the detection technique that cooperates the motor load electric current, thereby can automatically motor be reversed when when vehicle window rises, meeting with obstruction, and the safe anti-jamming device that vehicle window is descended automatically.
Background technology
The vehicle window of early stage vehicle is provided with wind, when desiring the lifting vehicle window, shakes thorny rocking handle, can operate window lifting manually.For asking convenient, depot just sets up motor, direction switch and linked component etc. in vehicle window later on, and the occupant only needs the hand direction switch, can make electronic rising of vehicle window or decline easily.Existing most motorized window, when pressing when by direction switch vehicle window being risen, if vehicle window meets with obstruction, when for example cramping was to occupant's hand, motor still can continuous running, so just can cause the danger that crushes a hand even cause injures and deaths.
Though dispose the safety device of the anti-cramping of motorized window in the present stage higher on the market part vehicle, conventional construction circuit complexity, cost is too high, just disposes so only limit to the high price car type; And adopting relay in the traditional structure, it is regular meeting's generation spark in use, so there is the danger of burning car; Moreover the derive shortcoming of loose contact of the spark that relay produced causes fault rate too high; Again, the anti-clamping and pressing device of existing motorized window often must carry out travel settings, quite trouble again after outage or changing vehicle accumulator.
Summary of the invention
One of the utility model purpose is to provide a kind of anti-jamming device of power windows, and when vehicle window rose, if cramping is to the end during obstruction such as hand, this anti-jamming device can make motor reverse automatically, to avoid crushing a hand, can reach security purpose.
Another purpose of the utility model is: design that a kind of circuit and structure design are simple and easy, cost is low, reliable not easy break-down and do not have the anti-jamming device of the power windows that spark produces, make its energy popularization and application in each vehicle, to guarantee the vehicle window safety of all vehicles.
For achieving the above object, the utility model provides a kind of anti-pinching car window device that is installed in the Vehicular door, is provided with between car door and vehicle window:
Motor is located at the vehicle window bottom, and it drives window lifting by linked component;
Microprocessor, it is integrated peripheral signal and controls in good time;
Fixedly inductive component and lifting inductive component, both are corresponding inductive component group, and wherein, fixedly inductive component and microprocessor link, and this lifting inductive component is located at vehicle window bottom appropriate location, and fixedly inductive component is located at appropriate location in the car door;
Direction switch is linked to microprocessor, in order to the control motor.
The anti-jamming device of power windows as mentioned above, wherein fixedly inductive component and lifting inductive component are magnetic red formula induction structure.
The anti-jamming device of power windows as mentioned above, wherein fixedly inductive component is located at the interior position of car door, this height rises to the top with vehicle window, fixedly inductive component can with lifting inductive component equal height the best.
The anti-jamming device of power windows as mentioned above, when vehicle window rises, when lifting was responded to thin part and fixedly inductive component is responded to because of pressing close to reach, microprocessor can make motor shut down.
The anti-jamming device of power windows as mentioned above, when vehicle window rises, if the lifting inductive component fail and fixedly inductive component press close to and can't respond to, and when microprocessor detects the motor load electric current above normal value, microprocessor can make motor reverse and fall vehicle window, discharge obstructions such as head, hand, and reach the effect of safe anti-pinch.

The specific embodiment
Form with regard to the structure of the anti-jamming device of the utility model power windows below, and the effect that is produced, in conjunction with the accompanying drawings, lift a preferred embodiment of the present utility model and describe in detail.
See also Fig. 1, the anti-jamming device of the utility model power windows includes:
Microprocessor 3 (CPU, control module) can be integrated peripheral signal and also control in good time;
Fixedly inductive component 4 and lifting inductive component 5, both be corresponding inductive component group, can be magnetic red formula induction structures, wherein, fixedly inductive component 4 and microprocessor 3 bindings;
Please in conjunction with Fig. 2, in this car door 7, be provided with vehicle window 71 again, vehicle window 71 bottom appropriate locations are provided with lifting inductive component 5, and fixedly inductive component 4 is fixed at appropriate location in the car door 7, when this height rises to the top with vehicle window 71, fixedly inductive component 4 can with lifting inductive component 5 equal height the bests.These vehicle window 71 bottoms are provided with linked component 11 and motor 1.
Under the normal condition, as Fig. 3, owing to be provided with lifting inductive component 5 at vehicle window 71 bottom appropriate locations, and appropriate location is provided with fixedly inductive component 4 in car door 7, when operation direction switch 6 rises vehicle window 71, if lifting inductive component 5 can with fixing inductive component 4 when pressing close to reach induction, the expression action is normal does not have danger, and vehicle window 71 has been raised to the top, and microprocessor 3 can make motor 1 shut down.
Otherwise, when making vehicle window 71, operation direction switch 6 rises, if lifting inductive component 5 fails to press close to and can't respond to (as shown in Figure 4) with fixing inductive component 4, and when microprocessor 3 detects motor 1 load current above normal value, representing promptly that vehicle window 71 rises does not reach the top and cramping obstruction 9 such as hand is to the end arranged, and this moment, microprocessor 3 can make motor 1 reverse at once, to fall vehicle window 71, discharge obstructions 9 such as a hand, and obtain the effect of safe anti-pinch.
Anti-jamming device of the present utility model mainly is the sense state of foundation two inductive components 4,5, cooperates the detecting of motor 1 load current, and therefore, action is accurate, even also need not reset behind outage or the replacing storage battery.
Used microprocessor 3 in the utility model, fixedly inductive component 4 and lifting inductive component 5 all can commercially availablely obtain.
In sum, be preferred embodiment of the present utility model only, be not in order to limit the utility model; All other do not break away from equivalence of the present utility model to be modified or displacement, all should be contained in the utility model scope.
