Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, a child restraint system with an automatic pre-tightening function includes a seat body 1, a shoulder belt 2, a belt connecting plate 3, a bottom belt 4, a control unit 5, a belt retractor assembly 6, a sensor integration unit 7, and a tension sensor 8.
4 front ends of bottom safety belt and safety belt coiler subassembly 6 fixed connection, safety belt coiler subassembly 6 fixed mounting is at the front end of seat body 1 base, 4 rear ends of bottom safety belt pass through safety belt connecting plate 3 and are connected with shoulder safety belt 2, and 4 rear ends of bottom safety belt pass through safety belt connecting plate 3 and are best connected with shoulder safety belt 2/3.
The sensor integration unit 7 is integrated with a gyroscope sensor and a gravity sensor, and the control unit 5 and the sensor integration unit 7 are fixed on the back of the seat body 1.
The control unit 5 is connected with the safety belt retractor assembly 6, the sensor integrated unit 7 and the tension sensor 8, and the control unit 5 receives signals transmitted by the sensor integrated unit 7 and the tension sensor 8, processes the signals and controls the safety belt retractor assembly 6 to tighten and loosen; the tension sensor 8 is fixed on the bottom safety belt 1 and is responsible for sensing the tension value on the bottom safety belt 4.
