Abstract

The invention relates to an electronic safety belt clamp which is a vehicular safety belt anti-tightening power device. A safety belt is clamped by two gears, different gears can be driven through the flexibility of the safety belt to rotate, different electromagnetic signals produced are transmitted to a microcomputer, the safety belt is controlled to be tightened and loosened by an electromagnetic switch, so that the safety belt does not tighten a driven after being tied up and can also automatically retract after being untied.

Description

The electronic security(ELSEC) strap clamp

Technical field

The electronic security(ELSEC) strap clamp is that a kind of safety strap of fastening that prevents when driving a car produces the device of the compressing of tying tight, the particularly automatic technique for fixing field of all car belts in the daily life.

Background technology

In normal life, when driving, we all must fasten one's safety belt, and the time that is has been grown and will think that people that safety strap is strangled is difficult to be subjected to and with it clothes is had abrasion action.

Summary of the invention

The objective of the invention is for people provide a kind of, the chaufeur of tying tight again under the effect of electronic security(ELSEC) strap clamp when fastening seat belts can automatically terminate again the device that fixedly makes safety strap energy automatic drawing back when unfastening one's seat-belt.The below illustrates the inventive principle of " electronic security(ELSEC) strap clamp " take (Fig. 1) as row: chaufeur just got on the bus fasten the safety belt in, driving 21,25 and 9 when outwards extracting 3 out rotates counterclockwise, 9 drive again 10 rotates, 10 rotations produce magnetoelectric inductions with 14 again, at 14 electric signal that produce, 14 electric signal transmission give 16,16 the electric signal of sending here for 14 first time are processed as signal a1, and 16 receive a1 only does memory and do not send instruction.Next what suitablely makes it the degree of tightness appropriateness and buckles well plug along with chaufeur is extracted safety strap out length, at this moment unclamping safety strap will bounce back and drive 21 and do and clockwise rotate, simultaneously 9 stop operating and 7 and 8 rotate, 7 drive 12 rotates, 12 rotate and 15 generation magnetoelectric inductions, produce

electric signal

15,15 electric signal transmission give 16,16 15 electric signal of sending here are for the first time processed as a signal b1, at this moment 16 receive b1 and send instruction to 17 at once and play moving electromagnetic valve and stretch out 13, make 13 to engage with 7, because 13 be to do the one-way wheel that clockwise rotates, at this moment will pin 7, thereby make 25 and 21 also to pin and stop operating, between safety strap will be sandwiched in 21 and 22 like this and can not reclaim, safety strap just can not tied chaufeur tight like this.When will getting off, opens first chaufeur the safety strap plug, then draw gently safety strap, will make like this 21 to do and rotate counterclockwise, and drive 7 and 9 and rotate, because 13 is single direction rotation gears, so it can not pin 7,7 can rotate to anticlockwise direction, 9 drive 10 rotates, and 10 rotations produce magnetoelectric inductions with 14 again, at 14 electric signal that produce, 14 electric signal transmission give 16,16 14 electric signal of sending here are for the second time processed as signal a2, and 16 receive the a2 signal sends to 17 at once and regain 13 instructions, and at this moment safety strap will regain 20 as long as chaufeur one is loosed one's grip.When regaining safety strap, can be with 21,8 and 12 to rotate, 12 rotate and 15 generation magnetoelectric inductions, produce

electric signal

15,15 electric signal transmission give 16,16 15 electric signal of sending here are for the second time processed as signal b2,16 do initialization process to 16 function after receiving signal b2, use preparing next time.So just having finished seeing of electronic security(ELSEC) strap clamp automatically locks and regains all processes.

The specific embodiment:

As shown in Figure 1: open 23 and lift 22 safety strap and fill between 21 and 22, buckle well 23 and to buckle well again loam cake, 12 volts of power supplys on the car are connected on 19, shell is buckled, be fixed on the place that safety strap has just been extracted out with 4 key screw electronic security(ELSEC) strap clamps, so that safety strap is capable of expansion and contraction, as shown in Figure 3: the electronic security(ELSEC) strap clamp of installation just can use.
