Device for protecting passengers

Abstract

The invention relates to a device for protecting passengers, which is characterized by comprising a control circuit, an electromagnet YA I and a locking component, wherein the electromagnet YA I is fixed in a vehicle, and the locking component can be worn at the back of a person and is made from an induced magnetism material; the control circuit comprises a power supply, a relay KR and a first switch installed in the vehicle; the power supply, the first switch and a coil of the relay KR are sequentially connected in series to form a closed loop, and both ends of a coil of the electromagnet YAI are connected with a pair of normally open contacts krl-l of the relay KR; when the power supply is switched on and the first switch is closed, the normally open contacts krl-l of the relay KR are closed, and the electromagnet YA I generates an electromagnetic field and sucks the locking component; and when the power supply is switched off, the normally open contacts krl-l of the relay KR recover a switching-off state, the electromagnetic field disappears, and the electromagnet YA I and the locking component are separated. The invention carries out locking by a magnetic article and has simple structure and manufacturing procedure, low cost, convenient use and stable locking effect.

Description

technical field [0001] The invention relates to a passenger protection device, in particular to a passenger protection device with simple and convenient operation, automatic locking and stable locking effect. Background technique [0002] People often need to take different means of transportation when they go out on a daily basis, the most common being a car; in order to ensure the safety of passengers and drivers, each seat is equipped with a protective device. At present, the main protection devices include safety belts and buckles that can be engaged with each other. One end of the safety belt and the buckle is fixed on the seat. Insert the free end of the buckle, and the two are locked, thus realizing. [0003] The design of the above-mentioned seat belts and buckles is mainly for adults, and younger children need help from other people when fastening or untying the seat belts; and the height of the current seat belt settings only considers adults The height of the ch...

Problems solved by technology

[0003] The design of the above-mentioned seat belts and buckles is mainly for adults, and younger children need help from other people when fastening or untying the seat belts; and the height of the current seat belt settings only considers adults The height of the child, the seat belt fastened by the child may just get stuck on the child's neck and other positions, making the child uncomfortable during the ride

In addition, for some people in special positions, for example, the driver may need to leave the seat many times, and repeatedly fastening and unfastening the seat belt will also cause inconvenience in use.

[0004] In addition, when there are not enough seats in the car, some passengers need to stand in the car. Generally, there are only some handrails in the car to lean on. When the car starts or stops, standing passengers are prone to body shaking due to inertia. even fall
