Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is arrangements for automotive doors anti-clipping system schematic diagram；
Fig. 2 is automobile side-door anti-clipping system arrangement schematic diagram；
Fig. 3 is automobile trunk chamber door anti-clipping system arrangement schematic diagram
Fig. 4 is limit mechanism structure schematic diagram.
Specific embodiment
Car door in arrangements for automotive doors anti-clipping system includes front door of automobile, automobile rear-door, automobile trunk chamber door.Such as Fig. 2
Shown in 3, eaves and lower eaves or doorframe left and right side are equipped with light-beam interruption inductor, light-beam interruption induction on doorframe
Device includes the infrared launcher along doorframe one of side arrangement, and is arranged in infrared launcher opposite side to receive its red
The infrared receiving device of external signal.Infrared induction has blocked infrared receiving device to receive infrared beam to after there is passenger to block,
Light-beam interruption inductor will transmit a signal to motor control unit, then it represents that the risk for having article or people to be gripped to.
Hinge, which is equipped with, obtains the dynamic Hall sensor of hinge opening and closing, and Hall sensor can obtain the opening degree of hinge
Number, can also get the folding condition of hinge, such as be presently at shutdown state or door opening state.
As shown in Figure 1, light-beam interruption inductor and Hall sensor output signal to motor control unit, motor control list
Member controls position-limit mechanism according to acquired signal, and control position-limit mechanism becomes between non-limit state and limitation hinge closed state
Change.When driving position-limit mechanism to move to limitation hinge closed state, motor control unit transmits a signal to vehicle control simultaneously
Unit processed, full-vehicle control unit will control reminder alarm device sending acoustic control alarm and reminding passenger and pay attention to closing door safety.
As shown in figure 4, position limiting structure includes motor, screw body, gear drive and spacer pin, spacer pin is located at hinge
Chain side, spacer pin is preferably parallel with the axis of hinge, is fixed on doorframe by guiding mechanism, and spacer pin can be along guiding
Mechanism activity, when position limiting structure is in non-limit state, spacer pin is located at outside hinge, when position limiting structure is in limitation hinge closure
State, spacer pin are located between the hinge of hinge, hinge can be prevented to be closed, play pinch resistant functionality.
Screw body includes the screw rod matched and feed screw nut, and spacer pin one end is fixed with silk towards hinge, the other end
Bar, screw rod is equipped with feed screw nut, while feed screw nut is fixed on doorframe by bearing, and feed screw nut is externally provided with to be passed with gear
The external tooth wheel construction of the output gear engagement of motivation structure, the input gear rotation of motor-driven gear transmission mechanism, due to screw rod
Nut is in stationary state, and when motor driven feed screw nut rotation, spacer pin can then be slided along guiding mechanism, make it non-
Limit state and limitation hinge closed state variation.Gear drive is immobilized in the shell and (constitutes gear box structure), the shell
Body is fixed on doorframe, and motor is equally fixed on doorframe, be can control motor by gear drive and is output to screw rod spiral shell
Torque on mother, and facilitate the fixation position of adjustment motor.
In order to accurately obtain the position of spacer pin, spacer pin is fixed with towards the contact that doorframe is arranged with screw rod junction and opens
It closes, the spacing block set positioned at contact-making switch stroke beginning and end is fixed on doorframe, contact-making switch outputs signal to motor control
Unit processed, then motor control unit can control the stopping opportunity of motor rotation, and the current rotating forward of driving by contact-making switch
Or it inverts.Spacer pin is towards the preferred wedge structure in hinge one end, even if wedge structure makes car door have been switched off very little angle
The state of degree, after infrared ray has sensed that passenger is blocked, spacer pin still be able to reliably to be inserted into hinge two panels hinge it
Between, and go deep into spacer pin insertion, hinge leaf can be made to separate, reduce the harm pressed from both sides.
Anti-clamping method based on above-mentioned arrangements for automotive doors anti-clipping system:
When some or multiple car door opening angles reach set angle (as setting need opening angle >=60 °), then open
The light-beam interruption inductor of car door is started to work, and the car door for only monitoring unlatching can be avoided false alarm, because of closing of the door state
Light-beam interruption inductor is necessarily in shielding status；
(signal is obtained by Hall sensor) during some closing of the door, if the induction zone of light-beam interruption inductor
There is barrier obstruction signal in domain, then after driving position-limit mechanism to move to limitation hinge closed state setting time, reverts to non-limit
Position state limits starting pinch resistant functionality and needs to have two conditions, i.e., currently closing the door and current beam interdicts inductor
Induction region have barrier obstruction signal, such double definition condition can be avoided in car door opening, hair when user gets off
Raw false alarm；
In addition, happening to further avoid false alarm, limitation hinge closure is moved to for driving position-limit mechanism
The qualifications of state can also increase by one, i.e., triple qualifications, increased qualifications are as follows: current car door opening angle
Less than setting value (such as 30 degree), can get off process to avoid user, close small car door conveniently and caused by false alarm, further increase
The reliability of system work and the accuracy of pinch resistant functionality starting；
After closing of the door, the light-beam interruption inductor for being turned off car door is closed.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
