Spring 7, hinged block 8, swing rod 9 and connecting rod 10, car bottom plate 5 are provided with groove 11, and pedal 6 is actively tied in groove 11, and spring 7 is set
Between the trough floor 12 of groove 11 and pedal 6, hinged block 8 is fixed in trough floor 12, and swing rod 9 is be hinged with hinged block 8, pendulum
The lower end of the left end 13 and connecting rod 10 of the hinge of bar 9 is hinged, and the upper end of connecting rod 10 and pedal 6 are be hinged, the right-hand member 14 of the hinge of swing rod 9
Provided with protection bolt 15, protection bolt 15 is used for positioned at the lower section of protection lockhole 5, the protection bolt 15 of swing rod 9 facing to protection lockhole 5
Prevent station from falling down school bus from car door in the children of car door 1.
The operation principle of school bus protection of the child door gear is：After the car door 1 of school bus is closed, if children stand in car door 1
Pedal 6 on when, the gravity of pedal 6 and children is more than the elastic force of spring 7, and pedal 6 is overcome under the elastic force of spring 7
Drop, make the protection bolt 15 of the right-hand member 14 of swing rod 9 upward to lower swing by the left end 13 of the pushing bar 9 of connecting rod 10 when pedal 6 declines
Swing, protection bolt 15 is inserted in the protection lockhole 5 of the lower end of car door 1, car door 1 is pinned, car door 1 is prevented car from opening
Door 1 is opened accidentally and children fall through car door 1.
In order to pin car door 1 when ensureing school bus driving, and implement parking and open automatically controlling for car door 1, lock a door guarantor
Protection unit 3 is provided with controller 16, and controller 16 is provided with velocity sensor 17, and velocity sensor 17 is located at the side of the wheel 18 of school bus
Side position, controller 16 are provided with driving protection switch 19, and protection switch 19 is normally closed switch, when school bus stops, velocity sensor
The signal that wheel 18 stops is transferred to controller 16 by 17, and it is closure state that controller 16, which controls protection switch 18, and school bus is walked
When, the signal that wheel 18 rotates is transferred to controller 16 by velocity sensor 17, and it is disjunction that controller 16, which controls protection switch 19,
State；Controller 16 is connected with protection switch 19, and the power connection of protection switch 19 and the driving element 20 of door drive 2 connects
Connect.During the closing of the door walking of school bus, protection switch 19 is disjunction state, and controller 16 is transported to the power supply quilt of driving element 20
Protection switch 19 is cut off, and car door 1 during driving from opening, is protected the safety of children.
During in order to implement school bus parking, the automatic unlocking of car door 1, protection device of locking a door 3 is provided with electronic tie rod 21, electronic drawing

23 positioned at the lower section of protection bolt 15.When school bus stops, the signal that wheel 18 stops is transferred to controller 16 by velocity sensor 17,
Controller 16 controls electronic tie rod 21 to be powered, and electronic tie rod 21 leaves behind the right-hand member 14 of the hinge of swing rod 9, makes the protection bolt of swing rod 9
15 leave protection lockhole 5；Meanwhile in the presence of the elastic force and the pulling force of electronic tie rod 21 of spring 7, pedal 6 is set to increase multiple
Position, opens car door 1.
In order to control the stroke that pedal 6 lifts, and ensure that the amplitude of oscillation of swing rod 9 can make 15 fully-inserted guarantor of protection bolt
Protect in lockhole 5, pin car door；The trough floor 12 of groove 11 is fixed with cylinder 24, and spring 7 is located in cylinder 24, and spring 7 is compression
Spring, the height of spring 7 are more than the height of cylinder 24, and the height of cylinder 24 is less than the distance that trough floor 12 arrives pedal 6, to ensure
Pedal 6 has the space of decline, and driving swing rod 9 is swung, while also limit the stroke of pedal 6.Pedal 6 overcomes spring 7
Elastic force decline when, spring 7 is compressed continuously into cylinder 24, and connecting rod 10 follows the decline of pedal 6 and constantly declined, pendulum
The left end 13 of bar 9 follows the decline of connecting rod 10 and constantly swung downwards, and the protection bolt 15 of the right-hand member 14 of swing rod 9 follows the pendulum of swing rod 9
Move and constantly insert the protection lockhole 5 of car door 1, when the fully-inserted protection lockhole 5 of protection bolt 15, on pedal 6 and cylinder 24
End contact, pedal 6, which declines, to be stopped, in the protection lockhole 5 for making the fully-inserted car door 1 of protection bolt 15.Spring 7 with cylinder 24
Difference in height be 20 millimeters to 30 millimeters, ensure protection bolt 15 reliably insert the protection lockhole 5 of car door 1 while, reduction pin
The distance that pedal 6 declines.
In order to prevent pedal 6 and the gap 26 of groove 11 from crushing children, flexible neonychium is set above pedal 6
25, neonychium 25 is highly connected with pedal 6, and the area of neonychium 25 is more than the area of groove 11, and neonychium 25 covers groove
11 with the gap 26 of pedal 6, prevent that gap 26 is exposed.
Described spring 7 is provided with multiple, and multiple springs 7 are symmetrical in the groove 11, the total elastic force of multiple springs 7
More than the gravity of pedal 6, it is not compressed with ensureing spring 7 to support pedal 6.The total elastic force of multiple springs 7
The gravity added up to less than children and pedal 6, to ensure children station in pedal 6, pedal 6 can overcome multiple springs 7
Elastic force decline.
In order to prevent the car door 1 of door drive 2 from opening car door for the state of unblock, it is provided with and connects in the protection lockhole 5 of car door 1
