Accompanying drawing explanation
Fig. 1 is the structural representation of school bus protection of the child door gear.
The specific embodiment
With specific embodiment, the present invention is further detailed with reference to the accompanying drawings below:
The structural representation of the school bus protection of the child door gear shown in Fig. 1, school bus protection of the child door gear, include car door 1 and door drive 2, school bus protection of the child door gear is provided with the protective device 3 of locking a door, and the protective device 3 of locking a door is installed on the car bottom plate 4 on car door 1 side, the lower end of the car door 1 of school bus is provided with protection lockhole 5, the protective device 3 of locking a door includes foot rest 6, spring 7, hinged block 8, fork 9 and connecting rod 10, car bottom plate 5 is provided with groove 11, foot rest 6 is actively tied in groove 11, spring 7 is located between the trough floor 12 and foot rest 6 of groove 11, hinged block 8 is fixed in trough floor 12, fork 9 is hinged with hinged block 8, the left end 13 of fork 9 hinges is hinged with the lower end of connecting rod 10, the upper end of connecting rod 10 and foot rest 6 are hinged, the right-hand member 14 of fork 9 hinges is provided with protection bolt 15, protection bolt 15 is positioned at the below of protection lockhole 5, the protection bolt 15 of fork 9 is facing to protection lockhole 5, for preventing that the children that stand in car door 1 from falling down school bus from car door.
The operating principle of school bus protection of the child door gear is: after the car door 1 of school bus is closed; if while having children to stand on the foot rest 6 of car door 1; foot rest 6 and children's gravity is greater than the elastic force of spring 7; the elastic force that foot rest 6 overcomes spring 7 declines; the left end 13 that foot rest 6 pushes away fork 9 by connecting rod 10 while declining is to lower swing; the protection bolt 15 of fork 9 right-hand members 14 is upwards swung; make to protect bolt 15 to insert in the protection lockhole 5 of car door 1 lower end; car door 1 is pinned; car door 1 can not be opened, prevent that car door 1 from surprisingly opening and children fall through car door 1.
In order to guarantee that school bus when driving pin car door 1, and the automatic control of implement stopping and to open car door 1, the protective device 3 of locking a door is provided with controller 16, controller 16 is provided with velocity sensor 17, velocity sensor 17 is located at the position, side of the wheel 18 of school bus, controller 16 is provided with driving protection switch 19, protection switch 19 is normally closed switch, when school bus stops, the signal that velocity sensor 17 stops wheel 18 is transferred to controller 16, it is closure state that controller 16 is controlled protection switch 18, during school bus walking, the signal that velocity sensor 17 rotates wheel 18 is transferred to controller 16, controller 16 is controlled protection switch 19 for disjunction state, controller 16 is connected with protection switch 19, and protection switch 19 is connected with the power connection of the driving element 20 of door drive 2.When the closing of the door of school bus is walked, protection switch 19 is disjunction state, and the protected switch 19 of power supply that controller 16 is transported to driving element 20 cuts off, and while making to drive a vehicle, car door 1 can not be opened, the safety of child protection.
While stopping in order to implement school bus; the automatic unlocking of car door 1, the protective device 3 of locking a door is provided with electronic tie rod 21, and the shell 22 of electronic tie rod 21 is fixedly connected with trough floor 12; the pull bar 23 of electronic tie rod 21 is hinged with the right-hand member 14 of fork 9 hinges, and pull bar 23 is positioned at the below of protection bolt 15.When school bus stops, the signal that velocity sensor 17 stops wheel 18 is transferred to controller 16, and controller 16 is controlled electronic tie rod 21 energisings, and electronic tie rod 21 is left behind the right-hand member 14 of fork 9 hinges, makes the protection bolt 15 of fork 9 leave protection lockhole 5; Meanwhile, under the elastic force of spring 7 and the effect of electronic tie rod 21 pulling force, make foot rest 6 increase and reset, car door 1 can be opened.
For the stroke of control pin pedal 6 liftings, and guarantee that the amplitude of oscillation of fork 9 can make to protect bolt 15 to insert completely in protection lockhole 5, pins car door; The trough floor 12 of groove 11 is fixed with cylinder 24, spring 7 is positioned at cylinder 24, spring 7 is Compress Spring, the height of spring 7 is greater than the height of cylinder 24, cylinder 24 is highly less than trough floor 12 to the distance of foot rest 6, to guarantee that foot rest 6 has the space of decline, drive fork 9 to swing, also limited the stroke of foot rest 6 simultaneously.When foot rest 6 overcomes the elastic force decline of spring 7; spring 7 is constantly compressed and is entered in cylinder 24; connecting rod 10 is followed the decline of foot rest 6 and is constantly declined; the left end 13 of fork 9 follow connecting rod 10 decline and constantly to lower swing; the protection bolt 15 of fork 9 right-hand members 14 is followed the swing of fork 9 and is constantly inserted the protection lockhole 5 of car door 1; when protection bolt 15 inserts protection lockhole 5 completely; foot rest 6 contacts with cylinder 24 upper surfaces; foot rest 6 declines and stops, in the protection lockhole 5 that makes to protect bolt 15 to insert car door 1 completely.Spring 7 and difference in height cylinder 24 are 20 millimeters to 30 millimeters, when guaranteeing the reliable protection lockhole 5 that inserts car doors 1 of protection bolt 15, reduce the distance that foot rest 6 declines.
In order to prevent that foot rest 6 and groove 11 gaps 26 from crushing children; above foot rest 6, be provided with flexible neonychium 25, neonychium 25 is highly connected with foot rest 6, and the area of neonychium 25 is greater than the area of groove 11; neonychium 25 covers the gap 26 of groove 11 and foot rest 6, prevents that gap 26 from exposing.
Described spring 7 is provided with a plurality of, and a plurality of springs 7 are symmetrical to be located in groove 11, and the elastic force that a plurality of springs 7 add up to is greater than the gravity of foot rest 6, not compressed to guarantee spring 7 can support foot rest 6.The elastic force that a plurality of springs 7 add up to is less than the gravity that children and foot rest 6 add up to, and when guaranteeing that children stand in foot rest 6, foot rest 6 can overcome the elastic force decline of a plurality of springs 7.
In order to prevent that door drive 2 car doors 1 from opening car door for the state of release, in the protection lockhole 5 of car door 1, be provided with approach switch 27, approach switch 27 is connected with controller.Door drive 2 is connected with controller 16; approach switch 27 is normally closed switch; protection bolt 15 inserts while protecting lockhole 5 to approach this approach switch 27; approach switch 27 disjunctions are transferred to controller 16 by its signal; controller 16 cuts off door drive 2 power supplys; in order to avoid protection bolt 15 inserts while protecting lockhole 5, door drive 2 is opened car door 1.
