Description
Technical field
The invention belongs to automotive safety equipment technical field, and in particular to a kind of car belt Based Intelligent Control pretension
System.
Background technology
Safety belt is one of main protection device of occupant restraint system, is indispensable on high speed moving vehicle seat
Device, the occupant caused by anxious acceleration produced when safety belt is by vehicle collision drastically enter row constraint and realize guarantor by displacement
Protective function, when collision scenario, by occupant restraint on the seat, the head and chest for making occupant are unlikely to forward safety belt
And steering wheel or instrument board etc. are hit, so that the danger that secondary collision occurs for occupant is reduced, and common safety belt is due to wearing
Webbing slack is caused in the gap existed when wearing between ribbon and occupant, causes it to have been played when colliding to occupant
The constraint of effect, thus the active preload Technique of safety belt is suggested.
Now widely used preload Technique is deflagration type pretension safety belt, and such pretension safety belt is sent out using exploding gas
Agent is given birth to drive ribbon backrush, but it can not be reused, the necessary integral replacing once igniting, therefore cost is higher.
The content of the invention
In order to solve the various accidents that automobile runs into the process of moving, and automotive safety pre-tightening apparatus can not
It is reused this problem.The elastic problem of ribbon can effectively be adjusted by the transmission of gear and tooth bar, can also quilt
Reuse, and reduce use cost.Therefore, the present invention provides a kind of car belt Based Intelligent Control pretensioner systems.
A kind of car belt Based Intelligent Control pretensioner systems of technical solution of the present invention, including ribbon drive device and control system
System, the ribbon drive device includes ribbon, ribbon spool, scroll support, gear, tooth bar and electric pushrod device；The control
System includes radar sensor, steering angle sensor, brake stroke sensor, velocity sensor and acceleration transducer；Can
Lead to the various threshold values of various sensors measurements to control the movement of electric pushrod device upper push-rod, the relative motion that push rod passes through chute
Movement with carry-over bar, makes pinion rotation drive the rotation of ribbon spool, controls the elasticity of ribbon.Improve human pilot reply
The security performance of various situations.
The present invention has the advantage that and good effect compared with prior art：
1st, technical solution of the present invention gathers coherent signal by pretension sensor, and controls electric pushrod device to act by controller
To drive ribbon spool to wind ribbon, electric pushrod device can do the straight reciprocating motion for extending, bouncing back by Electronic control, because
And reuse can be realized, cost is reduced,
2nd, at the same can before the collision occurs with regard to carry out pretension, can adequately protect occupant, in addition push rod be in retracted state
When, rack and pinion is not engaged, and the use of safety belt in the normal state is not influenceed.
3rd, a kind of car belt Based Intelligent Control pretensioner systems of the present invention, the controller is programmable controller
（PLC）.

Embodiment
For ease of skilled artisan understands that technical solution of the present invention, in conjunction with Figure of description to the technology of the present invention side
Case is described further.
As shown in Figures 1 and 2, a kind of car belt Based Intelligent Control pretensioner systems of the present invention, including including ribbon
1st, ribbon spool 2, scroll support 3, controller 4, radar sensor 5, steering angle sensor 6, brake stroke sensor 7, speed
Spend sensor 8, acceleration transducer 9, electric pushrod device 10, push rod 11, tooth bar 12, gear 13, sliding block 14, chute 15 and ribbon
Tension sensor 16.The travel switch of the electric pushrod device 10 is connected with controller 4, i.e., stroke is switched on by controller
It is connected with 4 controls, the push rod 11 of electric pushrod device 10 on tooth bar 12, the ribbon spool 2 and is arranged with gear 13, is pushed away when electronic
When bar device 10 is in elongation state, the tooth bar 12 is engaged with gear 13, and when electric pushrod 10 is in contraction state, tooth
Bar 12 is not contacted with gear 13.
One end of the tooth bar 12 is connected with push rod 11, the other end is provided with sliding block 14, the shell of electric pushrod device 10
Provided with the chute 15 being engaged with sliding block 14, the diameter parallel of the chute 15 and electric pushrod device 10.
The pretension control system also includes ribbon tension sensor 16, and the electric pushrod device 10 is provided with least two-stage row
Journey, the ribbon tension information that controller 4 is collected according to ribbon tension sensor 16 controls corresponding travel switch to open.
The controller 4 is programmable controller（PLC）.
Controller 4 described in technical solution of the present invention be previously set distance threshold, threshold speed, acceleration rate threshold, turn
To angle threshold, braking distance threshold value and ribbon tension threshold, wherein ribbon tension threshold is provided with least two, and each
Ribbon tension threshold corresponds to a stroke of electric pushrod device 10, when radar sensor 5, velocity sensor 8, acceleration sensing
Device 9, steering angle sensor 6 or the collection corresponding signal of brake stroke sensor 7 are passed back after controller 4, controller 4 and setting threshold
Value is compared, once the signal value collected exceeds respective threshold, what controller 4 will gather ribbon tension sensor 16
Signal is compared with threshold value, controls corresponding travel switch to open, and promotes push rod 11 to extend, in the elongation process of push rod 11, tooth
Bar 12 is engaged with gear 13, and promotes ribbon spool 2 to wind ribbon 1, realizes the pretension of safety belt.The present invention is touched in vehicle
Coherent signal can be gathered before hitting by pretension sensing system, control seat belt pretensioners wind ribbon 1, improved in advance
The protecting effect of safety belt, the push rod 11 of electric pushrod device 10 can do straight line back and forth movement, realize the weight of seat belt pretensioners
Use again, due to not contacted with gear 13 in contraction state hour rack 12 in electric pushrod device 10, thus in normal state, peace
Band is elastic freely adjustable entirely.
Invention is exemplarily described above in conjunction with accompanying drawing for technical solution of the present invention, it is clear that the present invention is implemented
