Switching mechanism.
The switching mechanism include be slidably arranged on casing 9a and both ends respectively with the first chuck 9f and the second chuck 9g
The sliding part 9h of setting is rotated, the sliding of sliding part 9h drives the first chuck 9f to be clamped or separate with first terminal gear 9b, together
When drive the second chuck 9g to separate or be clamped with second terminal gear 9c.Specifically, sliding part 9h, the first chuck 9f, the second card
The glide direction of disk 9g three is consistent.
The gear-box 9 further includes being rotatably arranged on operating parts 9j on casing 9a and for operating sliding part 9h sliding.
In this example, operating parts 9j is rotatablely connected by a shaft and casing 9a, the extending direction of the shaft and the sliding side of sliding part 9h
To consistent.
It is shown in Figure 9, sliding slot 9i is opened up on sliding part 9h, the length extending direction of sliding slot 9i and the cunning of sliding part 9h
Dynamic direction is perpendicular, and sliding slot 9i has two ends, which has displacement difference in the glide direction of sliding part 9h,
The one end part of operating parts 9j in sliding slot 9i and can along the chute 9i length direction sliding, when rotation operating parts 9j, make to operate
When the one end of part 9j is slid into positioned at the one end of sliding slot 9i, operating parts 9j drives sliding part 9h sliding, and then drives first
Chuck 9f is clamped with first terminal gear 9b phase, and the second chuck 9g is separated with second terminal gear 9c；As rotation operating parts 9j, make
When the one end of operating parts 9j is slid into positioned at the other end of sliding slot 9i, operating parts 9j drives sliding part 9h sliding, and then band
Dynamic second chuck 9g is clamped with second terminal gear 9c phase, and the first chuck 9f is separated with first terminal gear 9b.
In this example, the first output 9d of the gear-box 9 is fixedly connected with right rear wheel 6, the second output 9e and driving
One end of shaft 2 is fixedly connected, and the other end and rear left wheel 5 of drive shaft 2 are rotatablely connected.
Specifically, drive shaft 2 includes along the horizontal-extending main shaft section of left and right directions of children's electric motor vehicle, by main shaft section
Two bearings that both ends bend two linkage sections extended to form respectively, bent and extended to form respectively by two linkage sections
Section, two supporting sections are located at two side of left and right of main shaft section and parallel with main shaft section, one in two supporting sections and the
Two output 9e are fixedly connected, another is rotatablely connected with rear left wheel 5, and the connection component 8 and main shaft section of vehicle frame are rotatablely connected,
The rear end of sole 1 is rotatablely connected with two supporting sections respectively.
The working principle of the children's electric motor vehicle:
As rotation operating parts 9j, sliding part 9h is slided, drives the first chuck 9f to slide into and be clamped with first terminal gear 9b phase,
Sliding part 9h simultaneously drive the second chuck 9g separated with second terminal gear 9c, at this time the first chuck 9f, first terminal gear 9b,
First output 9d three is relatively fixed, and the first output 9d is fixedly connected with right rear wheel 6, first terminal gear 9b rotation
It drives the first output 9d to rotate, and then right rear wheel 6 is driven to rotate, children's electric motor vehicle normally travel.
As rotation operating parts 9j, sliding part 9h is slided, the second chuck 9g is driven to slide into and second terminal gear 9c phase
Clamping, sliding part 9h drives the first chuck 9f to separate with first terminal gear 9b simultaneously, at this point, the second chuck 9g, second terminal
Gear 9c, the second output 9e three are relatively fixed, and the second output 9e is fixedly connected with drive shaft 2, second terminal tooth
It takes turns 9c rotation and drives the second output 9e rotation, and then drive shaft 2 is driven to rotate, and the main shaft of vehicle frame and drive shaft 2
Section rotation connection, the rotation of drive shaft 2 drive vehicle frame to rock back and forth up and down, and children's ride-on has similar shake on electric vehicle at this time
Horse effect.
