When the child sits on the second cushion, the second button switch is closed; the safety door closing device is composed of electric components, the electric components include electric push rods or electromagnets, and the base of the electric components is fixedly connected with the door frame. The power head of the electric component faces the door. If there is a child in the car, the electric component is energized, and the power head stretches out to block the door so that the door cannot be closed, which is used to prevent children from being locked in the car; the controller has a first alarm The indicator light and the second alarm indicator light are used to indicate the situation in the car; the controller is provided with a control line connected with the first button switch and the second button switch. off and motorized components are connected.

校车儿童保护装置的工作原理是：司机打开车门后，汽车的控制系统传输一个开车门信号给控制器，校车儿童保护装置的控制器进入自动控制状态；司机打开车门未上车时，司机坐椅的第一按钮开关为常闭状态；儿童上车坐上儿童坐椅后，儿童坐椅的第二坐垫在儿童人体重力的作用下，克服第二按钮开关弹簧的弹力下降，使常开的第二按钮开关闭合；第二按钮开关将儿童坐上儿童坐椅的信号传输给控制器，控制器控制第一报警指示灯亮，用于表示儿童坐椅有儿童；同时，控制器控制安全关门装置的电动元件通电，电动元件的动力头伸出，挡住车门，使车门不能关闭；司机上车坐上司机坐椅后，司机坐椅的第一坐垫在司机人体重力的作用下，克服第一按钮开关弹簧的弹力下降，使常闭的第一按钮开关分断；第一按钮开关将司机坐上司机坐椅的信号传输给控制器，控制器控制切断电动元件的电源，电动元件的动力头复位缩回，使校车可以关门；司机关闭车门后行车将儿童送到目的地，儿童下车离开儿童坐椅后，儿童坐椅的第二坐垫在第二按钮开关弹簧的弹力的作用下复位上升，第二按钮开关由闭合复位到常开状态，第二按钮开关将儿童离开儿童坐椅的信号传输给控制器，控制器控制第一报警指示灯熄灭，使司机可以于控制器的第一报警指示灯了解到儿童离开儿童坐椅的情况；司机离开司机坐椅时，司机坐椅的第一坐垫在第一按钮开关弹簧的弹力的作用下复位上升，第一按钮开关由分断复位到常闭状态，第一按钮开关将司机离开司机坐椅的信号传输给控制器；司机离开司机坐椅后，如果儿童坐椅上还有儿童，儿童坐椅上第二按钮开关闭合，第二按钮开关将儿童坐椅还有儿童的信号传输给控制器，控制器控制安全关门装置的电动元件通电，电动元件的动力头伸出，挡住车门，使车门不能关闭，迫使司机或者老师检查车上是否还有儿童，防止儿童被关在车内，威胁儿童的生命。The working principle of the school bus child protection device is: after the driver opens the door, the car's control system transmits a signal to open the door to the controller, and the controller of the school bus child protection device enters the automatic control state; The first button switch is in the normally closed state; after the child gets on the car and sits on the child seat, the second cushion of the child seat overcomes the spring force of the second button switch spring under the action of the child's body weight, so that the normally open first button switch The second button switch is closed; the second button switch transmits the signal that the child sits on the child seat to the controller, and the controller controls the first alarm indicator to light up, which is used to indicate that there is a child in the child seat; at the same time, the controller controls the safety door closing device When the electric element is energized, the power head of the electric element stretches out to block the door so that the door cannot be closed; after the driver gets on the car and sits on the driver's seat, the first seat cushion of the driver's seat overcomes the first button switch under the action of the driver's body weight. The elastic force of the spring drops, so that the normally closed first button switch is broken; the first button switch transmits the signal that the driver sits on the driver's seat to the controller, and the controller controls to cut off the power supply of the electric element, and the power head of the electric element resets and retracts , so that the school bus can close the door; the driver closes the door and drives the child to the destination. After the child gets off the car and leaves the child seat, the second seat cushion of the child seat returns and rises under the elastic force of the second button switch spring. The button switch is reset from closed to normally open state, and the second button switch transmits the signal that the child leaves the child seat to the controller, and the controller controls the first alarm indicator light to go out, so that the driver can know from the first alarm indicator light of the controller When the child leaves the child's seat; when the driver leaves the driver's seat, the first seat cushion of the driver's seat will reset and rise under the elastic force of the first button switch spring, and the first button switch will reset to the normally closed state from the disconnection. A button switch transmits the signal that the driver leaves the driver's seat to the controller; after the driver leaves the driver's seat, if there are children on the child seat, the second button switch on the child seat is closed, and the second button switch turns the child seat There are also children's signals transmitted to the controller, and the controller controls the power-on of the electric element of the safety door closing device. The child was locked in the car, threatening the life of the child.

本发明的有益效果是：校车儿童保护装置设有多重的保护功能，利用校车的司机坐椅、儿童坐椅以及安全关门装置对校车内的情况进行监控以及控制，如果儿童遗留在车内的儿童坐椅、儿童坐椅侧面或者下面时，控制器控制车门不能关闭，迫使司机或者老师检查车上是否遗留儿童，有效防止了将儿童遗留在车上。The beneficial effects of the present invention are: the school bus child protection device is equipped with multiple protection functions, and the driver's seat, child seat and safety door closing device of the school bus are used to monitor and control the situation in the school bus. When the seat or child seat is on the side or below, the controller controls the door to not close, forcing the driver or teacher to check whether there are children left in the car, effectively preventing children from being left in the car.
