Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
It is a kind of with the automatic child restrainnt system for pre-tightening function, including seat body 1, shoulder in conjunction with Fig. 1, Fig. 2 and Fig. 3
Portion's safety belt 2, safe strip connecting plate 3, bottom safety band 4, control unit 5, seat belt retractor component 6, sensor integration list
First 7, tension sensor 8.
4 front end of bottom safety band is fixedly connected with seat belt retractor component 6, the seat belt retractor component 6
It is fixedly mounted on the front end of 1 pedestal of seat body, 4 rear end of bottom safety band passes through safe strip connecting plate 3 and shoulder safety
Band 2 connects, and 4 rear end of bottom safety band is preferably connect with shoulder safety belt 2/3 by safe strip connecting plate 3.
Gyro sensor and gravity sensor, control unit 5, sensor are integrated on the sensor integration unit 7
Integrated unit 7 is fixed on the back of seat body 1.
Described control unit 5 is connected with seat belt retractor component 6, sensor integration unit 7, tension sensor 8, control
The signal that 5 receiving sensor integrated unit 7 of unit, tension sensor 8 transmit, and signal is handled, control safety belt volume
It receives the tightening of device assembly 6 and loosens；The tension sensor 8 is fixed on bottom safety band 1, is responsible on perception bottom safety band 4
Value of thrust.
Safe strip connecting plate 3 is prepared by stainless steel plate.
When specific works: after children are placed on seat and fix children with safety belt according to correct way by parent,
The meeting automatic tightening bottom safety band 4 of seat belt retractor component 6, and shoulder safety belt 2/3 is tightened by safe strip connecting plate 3,
To which the fixed of children when tension sensor 8 perceives the pulling force on safety belt and meets or exceeds certain numerical value, will be believed
