In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

A child protection device includes a flexible board, a top side wall of the flexible board is provided with a first through hole along a vertical direction, an airbag with an annular structure is installed on the top side wall of the flexible board, and the first through hole is arranged on the top side wall of the flexible board. The hole is located in the inner circle of the airbag, the four side walls of the flexible plate are all provided with a first groove, the inside of the first groove is fixed with a displacement sensor, and the top of the flexible plate is provided with two sets of symmetrically arranged second grooves The inside of the second groove is fixed with an air pump, and the output end of the air pump is communicated with the air bag through the air pipe. The top side wall of the flexible plate is provided with a third groove, and a control box is fixed inside the third groove. The internal settings of the MCU are provided.

Preferably, the input end of the single-chip microcomputer is connected with a displacement sensor, and the output end of the single-chip microcomputer is connected with an air pump.

Preferably, two sets of symmetrically arranged Velcro rough surfaces and Velcro hook surfaces are fixed on the bottom end sidewall of the flexible board.

Preferably, a battery holder is embedded in the top side wall of the flexible board, and the battery holder is connected with the displacement sensor, the air pump and the single-chip microcomputer through wires.

Compared with the prior art, the beneficial effects of the present utility model are:

Through the cooperation between the flexible board, displacement sensor, airbag, battery holder, control box, Velcro surface and Velcro hook surface, the child's head can be protected and the safety of the child is improved. It has little impact on children's actions and improves practicality.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-3, a child protection device includes a flexible board 1, the top side wall of the flexible board 1 is provided with a first through hole 2 along the vertical direction, and the top side wall of the flexible board 1 is installed with a ring-shaped structure The airbag 3, and the first through hole 2 is located in the inner circle of the airbag 3, the four side walls of the flexible board 1 are provided with a first groove 4, the inside of the first groove 4 is fixed with a displacement sensor 5, and the top end of the flexible board 1 There are two sets of symmetrically arranged second grooves 6, an air pump 7 is fixed inside the second groove 6, the output end of the air pump 7 is communicated with the air bag 3 through the air pipe, and the top side wall of the flexible plate 1 is provided with a third groove. , a control box 9 is fixed inside the third groove, and a single-chip microcomputer is arranged inside the control box 9 .

The input end of the single-chip microcomputer is connected with a displacement sensor 5, the output end of the single-chip microcomputer is connected with an air pump 7, and two sets of symmetrically arranged Velcro wool surfaces 11 and Velcro hook surfaces are fixed on the bottom side wall of the flexible board 1. A battery holder 8 is embedded in the side wall of the top end, and the battery holder 8 is connected with the displacement sensor 5, the air pump 7 and the single-chip microcomputer through wires.

Working principle: When the child uses it, the child passes the head through the first through hole 2, and then uses the Velcro hook surface 10 and the Velcro wool surface 11 to fix the shoulder head, and then the child is playing or riding. When the child falls, when one of the displacement sensors 5 of the AHS-150 model detects that the distance from the ground exceeds the set limit value, the signal sensor is transmitted to the single-chip microcomputer of the MSP430 model, and the single-chip computer controls the four air pumps 7 to start. The air pump 7 inflates the air bag 3 quickly, and then controls the air pump 7 to close, the air bag is inflated, and the head is protected. After the protection is completed, the air bag 3 is opened by opening the deflation switch. Protection and protection improve the safety of children, and at the same time, it has little impact on children's actions and improves practicability.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
