It is described control hinge rotate control device include contactor, electronic control unit, protective resistance, power supply, turn
Fast sensor, disk brake controlling switch, an input of described electronic control unit pass through feeder line and revolution speed sensing
Device is connected, and obtains the tach signal that speed probe is inputted in real time, and disk brake controlling switch is serially connected in electronic control unit
Another input, power supply is connected with electronic control unit, between power supply and electronic control unit provided with contactor and
Protective resistance.
Described disc type braking tong is fixedly mounted on the vehicle body not rotated with car door and turns over 80 ° by opening positioned at car door
Place.
After such scheme, because the utility model uses electronic control technology, by hinge and the ingenious combination of disk brake
Get up, the angular speed of closing of the door is controlled by disk brake, the dynamics of closed door is controlled so as to realize
System, effectively prevents closing of the door mistiming from crushing the generation of passenger's accident, and the method with safe and reliable advantage and use is easy to
Realize.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of car door preventing damage system, including body hinge 1, disc type brake dress
Put 2, control device 3 and the car door limiter worked side by side with the utility model 4.
Described disc brake apparatus 2 includes brake disc 21, disc type braking tong 22.Described brake disc 21 is a quarter
Annular disk, it is fixedly mounted on the bottom of body hinge 1, and disc type braking tong 22 is fixedly mounted on the vehicle body not rotated with car door
80 ° above and positioned at car door by opening are turned over, disc type braking tong 22 is relative with brake disc 21, the angle speed in control device 3 is sensed
Device 35 is arranged on disc type braking tong 22（As shown in Figure 3）, can be accurately real-time and the fast sensor 35 in the angle is relative with brake disc 21
The angular speed for the body hinge 1 being connected with car door is measured, and signal is transmitted to the operating circuit that control hinge is rotated.
As shown in Figure 5-Figure 7, the car door limiter 4 is arranged between vehicle body 10 and car door 20, and limitation car door 20 is turned over
Maximum angle a be less than 80 °.
As shown in Fig. 4, Fig. 6, the control device 3 that the control hinge is rotated includes contactor 31, electronic control unit
（ECU）32nd, protective resistance 33, power supply 34, speed probe 35, disk brake controlling switch 36, All other routes；Described electricity
Sub-control unit（ECU）32 input is connected by feeder line with speed probe 35, obtains speed probe 35 real-time
The tach signal of input, disk brake controlling switch 36 is serially connected in electronic control unit（ECU）32 another input, electricity
Source 34 and electronic control unit（ECU）32 connections, in power supply 34 and electronic control unit（ECU）Contactor 31 is provided between 32
With protective resistance 33.Described contactor 31 controls circuit state in 20 open mode of car door to connect, when car door 20 is closed
When closing, contactor 31 is off-state.
The operation principle of the utility model control device 3：
The electronic control unit（ECU）32 by obtaining the tach signal that speed probe 35 is inputted in real time, to disc type
Brake apparatus 2 carries out being turned on and off control, and the rotating speed that the speed probe 35 can be delicately to car door 20 around hinged place enters
Row monitoring；When a vehicle door is closed angular speed it is too fast i.e. closed door 20 exert oneself it is excessive when, electronic control unit（ECU）32 by connecing
Logical disc brake apparatus 2, slows down to the angular speed of car door 20, when angular speed is reduced to the certain value scope i.e. closing forces of car door 20
Degree be slightly larger than or can just closed door 20 when, electronic control unit（ECU）32 disconnect the work electricity of disc brake apparatus 2
Road, makes car door 20 smoothly be closed with less speed.
As shown in Fig. 1, Fig. 7, Fig. 4, the utility model additionally provides a kind of car using above-mentioned car door preventing damage system
Door preventing damage method：
When car door 20 close rotating speed it is too fast, electronic control unit（ECU）32 connection disc brake apparatus 2 are carried out to car door 20
Slow down；When the rotating speed of car door 20 that the fast sensor 35 in angle on control device 3 is measured reach can just closed door 20 angular speed
When, electronic control unit（ECU）32 survey the signal-off disc brake apparatus 2 of conveying according to the fast sensor 35 in angle, now car door
20 dynamics closed are smaller, when the finger of people is stuck at closing, will not be crushed by serious, simply slight squeeze,
So as to effectively prevent car door 20 from closing generation of the great efforts passenger's finger pinch off.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description all should still belong to this reality
In the range of being covered with new patent.
