The pin 15 is located below the protection key hole 5, and the protection pin 15 of the swing lever 9 faces the protection key hole 5 for preventing the child standing at the door 1 from falling off the school bus from the door.
校车儿童保护门装置的工作原理是：校车的车门1关闭后，如果有儿童站在车门1的脚踏板6上时，脚踏板6以及儿童的重力大于弹簧7的弹力，脚踏板6克服弹簧7的弹力下降，脚踏板6下降时通过连杆10推摆杆9的左端13向下摆动，使摆杆9右端14的保护栓15向上摆动，使保护栓15插入车门1下端的保护锁孔5内，将车门1锁住，使车门1不能打开，防止车门1意外打开以及儿童经车门1跌下。
The working principle of the school bus child protection door device is: after the door 1 of the school bus is closed, if the child stands on the foot pedal 6 of the door 1, the foot pedal 6 and the gravity of the child are greater than the spring force of the spring 7, the foot pedal 6 When the pedal 6 is lowered, the left end 13 of the swing lever 9 of the connecting rod 10 is swung downward, and the protection bolt 15 of the right end 14 of the swing lever 9 is swung upward, so that the protective plug 15 is inserted into the lower end of the door 1. In the protective keyhole 5, the door 1 is locked, so that the door 1 cannot be opened, the door 1 is prevented from being accidentally opened, and the child is dropped by the door 1.
为了保证校车行车时将车门1锁住，以及实施停车打开车门1的自动控制，锁门保护装置3设有控制器16，控制器16设有速度传感器17，速度传感器17设于校车的车轮18的旁边位置，控制器16设有行车保护开关19，保护开关19为常闭开关，校车停车时，速度传感器17将车轮18停止的信号传输给控制器16，控制器16控制保护开关18为闭合状态，校车行走时，速度传感器17将车轮18转动的信号传输给控制器16，控制器16控制保护开关19为分断状态；控制器16与保护开关19连接，保护开关19与门驱动装置2的驱动元件20的电源接头连接。校车的车门关闭行走时，保护开关19为分断状态，控制器16输送到驱动元件20的电源被保护开关19切断，使行车时车门1不能打开，保护儿童的安全。In order to ensure that the door 1 is locked when the school bus is driving, and the automatic control of the parking door 1 is implemented, the door protection device 3 is provided with a controller 16, and the controller 16 is provided with a speed sensor 17, which is provided on the wheel 18 of the school bus. In the side position, the controller 16 is provided with a driving protection switch 19, and the protection switch 19 is a normally closed switch. When the school bus stops, the speed sensor 17 transmits a signal for stopping the wheel 18 to the controller 16, and the controller 16 controls the protection switch 18 to be closed. In the state, when the school bus is walking, the speed sensor 17 transmits a signal for rotating the wheel 18 to the controller 16, and the controller 16 controls the protection switch 19 to be in a disconnected state; the controller 16 is connected to the protection switch 19, and the protection switch 19 and the door driving device 2 are The power connector of the drive element 20 is connected. When the door of the school bus is closed, the protection switch 19 is in a disconnected state, and the power supplied from the controller 16 to the drive element 20 is cut off by the protection switch 19, so that the door 1 cannot be opened during driving, and the safety of the child is protected.
为了实施校车停车时，车门1的自动解锁，锁门保护装置3设有电动拉杆21，电动拉杆21的外壳22与槽底板12固定连接，电动拉杆21的拉杆23与摆杆9铰轴的右端14铰接，拉杆23位于保护栓15的下方。校车停车时，速度传感器17将车轮18停止的信号传输给控制器16，控制器16控制电动拉杆21通电，电动拉杆21将摆杆9铰轴的右端14拉下，使摆杆9的保护栓15离开保护锁孔5；同时，在弹簧7的弹力以及电动拉杆21拉力的作用下，使脚踏板6上升复位，使车门1可以打开。In order to realize the automatic unlocking of the door 1 when the school bus is parked, the door lock protection device 3 is provided with an electric pull rod 21, and the outer casing 22 of the electric pull rod 21 is fixedly connected with the groove bottom plate 12, and the pull rod 23 of the electric pull rod 21 and the right end of the swing rod 9 are hinged 14 hinged, the pull rod 23 is located below the protection plug 15. When the school bus stops, the speed sensor 17 transmits a signal that the wheel 18 stops to the controller 16, the controller 16 controls the electric pull rod 21 to be energized, and the electric pull rod 21 pulls down the right end 14 of the swing rod 9 to make the swing rod 9 15 leaves the protection key hole 5; at the same time, under the action of the spring force of the spring 7 and the pulling force of the electric pull rod 21, the foot pedal 6 is raised and reset, so that the door 1 can be opened.
为了控制脚踏板6升降的行程，以及保证摆杆9的摆幅可以使保护栓15完全插入保护锁孔5内，锁住车门；凹槽11的槽底板12固定有圆筒24，弹簧7位于圆筒24内，弹簧7为压缩弹簧，弹簧7的高度大于圆筒24的高度，圆筒24高度小于槽底板12到脚踏板6的距离，以保证脚踏板6有下降的空间，驱动摆杆9摆动，同时也限制了脚踏板6的行程。脚踏板6克服弹簧7的弹力下降时，弹簧7被不断压缩进入圆筒24内，连杆10跟随脚踏板6的下降而不断下降，摆杆9的左端13跟随连杆10的下降而不断向下摆动，摆杆9右端14的保护栓15跟随摆杆9的摆动而不断插入车门1的保护锁孔5，当保护栓15完全插入保护锁孔5时，脚踏板6与圆筒24上端面接触，脚踏板6下降停止，使保护栓15完全插入车门1的保护锁孔5内。弹簧7的与圆筒24的高度差为20毫米至30毫米，在保证保护栓15可靠插入车门1的保护锁孔5的同时，减少脚踏板6下降的距离。In order to control the stroke of the lifting and lowering of the footrest 6, and to ensure that the swing of the swinging lever 9 can completely insert the protective plug 15 into the protective locking hole 5, the door is locked; the groove bottom plate 12 of the recess 11 is fixed with the cylinder 24, the spring 7 Located in the cylinder 24, the spring 7 is a compression spring, the height of the spring 7 is greater than the height of the cylinder 24, and the height of the cylinder 24 is smaller than the distance from the groove bottom plate 12 to the footboard 6, to ensure that the footboard 6 has a space to be lowered. The swing of the swing lever 9 is also oscillated while also limiting the stroke of the footrest 6. When the footrest 6 is lowered against the elastic force of the spring 7, the spring 7 is continuously compressed into the cylinder 24, and the link 10 is continuously lowered following the lowering of the footrest 6, and the left end 13 of the swing lever 9 follows the lowering of the link 10. Continuously swinging downward, the protection pin 15 of the right end 14 of the swing lever 9 is continuously inserted into the protection lock hole 5 of the door 1 following the swing of the swing lever 9, and when the protection plug 15 is fully inserted into the protection lock hole 5, the foot pedal 6 and the cylinder When the upper end surface of the 24 is in contact, the footrest 6 is lowered and stopped, so that the protective plug 15 is completely inserted into the protective keyhole 5 of the door 1. The height difference between the spring 7 and the cylinder 24 is 20 mm to 30 mm, and the distance at which the footrest 6 is lowered is reduced while ensuring that the protective plug 15 is reliably inserted into the protective keyhole 5 of the door 1.
