Background technology
At present, domestic passenger doors anti-pinch mainly has：Electronic delay anti-pinch, pressure switch anti-pinch, air bag anti-pinch；Electronics is prevented
Folder is had a great influence by door system resistance and speed, especially at ramp, has anti-grip force bigger than normal or the possibility of automatic anti-pinch；Pressure is opened
Official seal folder is had a great influence by air pressure；Air bag anti-pinch is as tracheae fractures or adhesive tape is damaged and fail；Pass can only be realized simultaneously
Door anti-pinch.
The content of the invention
For the limitation of passenger doors anti-pinch in the prior art, the utility model provides a kind of using the new of encoder
Passenger doors anti-pinch device, effectively solves above mentioned problem.
The technical scheme is that：
A kind of new passenger doors anti-pinch device, described device is by door pivot 1, tooth fan 2, connecting plate 3, encoder 4, encoder
Gear 5, door control unit 6, power part 7, connecting rod 8, supporting plate 9 form.
The lower end of door pivot 1 is fixed on vehicle body, upper end is connected by bearing with supporting plate 9, and tooth fans 2 endoporus and passes through spline
It is connected with door pivot 1, tooth is fanned and the synchronous rotary of door pivot 1.Connecting plate 3 is connected by screw with encoder 4, encoder 4 passes through
Connecting plate 3 is fixed on supporting plate 9, and encoder 4 is connected, by wire harness and gate control list with crossing front end spindle nose with encoder gear 5
Member 6 is connected, encoder gear 5 ensures to engage and transmits motion with tooth fan 2；Power part 7, which is fixed on door system installing plate, to be led to
Cross that bearing pin is connected with connecting rod 8, connecting rod 8 is connected by spline with door pivot.
Engaged by tooth fan 2 with encoder gear 5, the rotary state of door pivot 1 is converted into encoder turn signal：
Engaged by tooth fan 2 with encoder gear 5, the rotational angular velocity information of door pivot 1 is converted into detectable electricity
Subsignal.
Engaged by tooth fan 2 with encoder gear 5, the rotating signal of door pivot 1 is changed into level pulse signal.
When door runs into barrier during opening and closing, the level pulse signal of encoder changes, gate control list
Member 6 is according to pulse change, by algorithm, calculates the motion state of door switch process, and detection door runs into the state of barrier when closing,
Realize the function of shutdown anti-pinch.
The beneficial effects of the utility model：
The utility model discloses a kind of new passenger doors anti-pinch device, existing passenger doors anti-pinch technology is efficiently solved
The problem of existing, move towards international market for passenger doors and lay a good foundation.
Brief description of the drawings
Fig. 1 is a kind of new passenger doors anti-pinch device of the utility model specific embodiment.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of new passenger doors anti-pinch device includes door pivot 1, tooth fan 2, connecting plate 3, encoder 4, volume
Code device gear 5, door control unit 6, power part 7, connecting rod 8 and supporting plate 9.
The lower end of door pivot 1 is fixed on vehicle body, upper end is connected by bearing with supporting plate 9, tooth fan 2 by the spline of endoporus with
Door pivot 1 be connected, tooth fan 2 and with the synchronous rotary of door pivot 1.Connecting plate 3 is connected by screw with encoder 4, and encoder 4 passes through
Front end spindle nose is connected with encoder gear 5, encoder 4 is connected by wire harness with door control unit 6, encoder gear 5 fans 2 with tooth
Engagement, tooth fan 2 transmit motion, that is, that transmits door pivot 1 moves to encoder 4；Power part 7 is fixed on door system installing plate
It is connected by bearing pin with connecting rod 8, connecting rod 8 is connected by spline with door pivot.
Door control unit 6 calculates the stroke area of anti-pinch by self-checking function, automatic detection and the total kilometres parameter for storing door
The travel position of section and disconnected anti-pinch, reach the door opening aperture different conditions of adaptive various vehicles；
(1) umber of pulse and pulse frequency change curve of the automatic storage switch door of door control unit 6, and adjustment can be set,
As pulse change actual value exceedes setting value, detection of obstacles is activated.Pulse frequency change amplitude be not it is constant, it
Changed to determine by the position of door and the preceding motion impulse of shutdown several times frequency.Even the power-off of Electron door control device,
The related ginseng amperage of pulse also can be stored, so Electron door control device is installed on other any doors, it is necessary to by pressing down
Safeguard that the mode of button carries out beginning adaptation function setting and (under door closure state, enters self-adapting detecting shape by snapper
State, realize door opening action once, Electron door control device meeting automatic detection relevant parameter simultaneously stores).
(3) in door closing procedure, when running into barrier, Electron door control device by detecting the level pulse of encoder in real time
Signal, algorithm calculate the chance barrier state of shutdown, and pinch resistant functionality starts immediately, and the automatic enabling signal that triggers opens door, realizes anti-
Press from both sides function.
The course of work：
By door closing switch, power part (7) driving door pivot (1) rotation, with the door-plate that door pivot (1) is connected to shutdown side
To motion, when running into barrier in door-plate motion process (abnormal resistance), door pivot (1) rotary speed changes, and passes through
The encoder rotary speed that transmission motion is engaged with encoder gear changes, and encoder is output to door control unit (6)
Pulse frequency changes.Door control unit (6) carries out it with the umber of pulse and pulse frequency change curve for gathering switch gate
Compare, provide enabling signal, realize pinch resistant functionality.
Although the utility model is disclosed as above, they be not for limiting the utility model, it is any to be familiar with this skill
Skill person, without departing from the spirit and scope of the invention, it can make various changes or retouch from working as, but also belong to the guarantor of the present invention
Protect scope.What therefore the present invention should be defined by claims hereof protection domain is defined.
