Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1, Fig. 2 and Fig. 3 a, Fig. 3 b are referred to, is respectively the stereogram, just of the electronic induction coiler 100 of an embodiment
View and motion state schematic diagram.As shown in Figure 1, electronic induction coiler, for furling safety belt, the electronic induction coiler
Including frame 110, spool 120.Its middle frame 110, for accommodating safety belt.Spool 120, for winding safety belt, the spool
120 are arranged in frame 110, and frame 110 is stretched out in one end.
The electronic induction coiler 100 further includes the first induction module 150, electromagnetic switch 160 and control module 170.
First induction module 150 and the communication connection of control module 170, first induction module 150 are used for the angle of induction frame 110
Signal and/or acceleration signal, and angle signal and/or acceleration signal are sent to control module 170.Due to frame 110
Fixed compared with automobile, thus actually the first induction module 150 sensing be body of a motor car angle signal and acceleration
Spend signal.Electromagnetic switch 160 is arranged on frame 110, for controlling the rotation of spool 120 and locking, so as to lock this
Electronic induction coiler 100.Communication connection the first induction module 150 and electromagnetic switch 160 of control module 170, for according to the
Angle and/or acceleration signal the control electromagnetic switch 160 that one induction module 150 senses.
When automobile normal running, the safety belt in electronic induction coiler can freely pull out retracting.Work as running car
In tilted road surface, automobile has certain inclination angle, which can be sensed by the first induction module 150, when the inclination
When angle reaches a threshold value, the first induction module 150 can transfer angle signal to control module 170, and control module 170 detects
The angle signal passed over to the first induction module 150, control electromagnetic switch 160 lock coiler.Or work as automobile urgent brake
Vehicle or when colliding, automobile has certain acceleration that subtracts, i.e. acceleration is negative that this subtracts acceleration can be by the first induction module
150 sense, when this, which subtracts acceleration, reaches a threshold value, the first induction module 150 can transfer this and subtract acceleration signal
To control module 170, control module 170 detects the acceleration signal that subtracts that the first induction module 150 passes over, and controls electromagnetism
160 locking coiler of switch.In this way, electromagnetism is controlled according to the signal of the transmission of the first induction module 150 by control module 170
Switch 160 carrys out seatbelt lock, by the sensing of electronic induction rather than machine components, on the one hand can effectively reduce automobile peace
The noise of full band, and the retracting accuracy of coiler can be effectively improved so that the retracting controllability higher of safety belt, and
Do not sense hysteresis, improve the real-time of control.It on the other hand, can with the first induction module 150 instead of machine components
The number of parts of entire safety belt assembly is reduced, reduces cost.
In the present embodiment, which can also include the second induction module 180, second sensing
Module 180 and spool 120 and control module 170 connect, and can be rotated with spool 120, and the angle of sensing spool 120 accelerates
Degree, and the angular acceleration is sent to control module 170.Control module 170 is opened according to the angular acceleration received, control electromagnetism
Close 160.When automobile collides, the shoulder of occupant can pull safety belt at high speed, so as to drive spool 120 and second
180 synchronous rotary of induction module, control module 170 real-time monitor the angular acceleration letter that the second induction module 180 passes over
Number, when the angular acceleration reaches a threshold value, control module 170 can send drive signal to electromagnetism by data processing
Switch 160, control electromagnetic switch 160 lock coiler.So as to further assure that the real-time of control and accuracy.
Preferably, in the present embodiment, which further includes latch ratchet 130 and locking pawl 140.
The latch ratchet 130 is connected from the outside of frame 110 and spool 120, can be rotated with spool 120.Locking pawl 140 is arranged on locking
