Embodiment
In order to more fully understand technology contents of the present utility model, with reference to schematic diagram to technical side of the present utility model
Case is further described and illustrated, but is not limited to this.
A kind of baby stroller, including:Vehicle frame, seat, drive device.Vehicle frame is provided with handle, and seat is provided with backrest, seat
It is rotationally connected with vehicle frame.Drive device includes the first rotating shaft with handle rotation connection, is fixed on the first cam of first rotating shaft,
It is fixed on handle and the motor for driving first rotating shaft to rotate.First cam is provided with crank slot, and the back of backrest, which is provided with, to be used to slide
The dynamic driving member for being connected to crank slot, during the first cam rotation, it drives seat to be swung around vehicle frame, the angle that seat is swung around vehicle frame
Scope is 0-30 °.
As shown in Figure 1 and Figure 2, a kind of baby stroller 10, including:Vehicle frame 1, seat 2, drive device 3.Vehicle frame 1 is provided with handle
Hand 11, seat 2 are provided with backrest 21, and seat 2 is rotationally connected with vehicle frame 1.Drive device 3 includes first be rotatablely connected with handle 11
Rotating shaft 31, the first cam 32 of first rotating shaft 31 is fixed on, is fixed on handle 11 and the electricity for driving first rotating shaft 31 to rotate
Machine 33.First cam 32 is provided with crank slot 321, and the back of backrest 21 is provided with the driving member 211 for being used for being slidably connected to crank slot 321.
When first cam 32 rotates, it drives seat 2 to be swung around vehicle frame 1, so as to play a part of cradle, also, and can
Used as trolley 10.Seat 2 is 0-30 ° around the angular range that vehicle frame 1 is swung, and its angular range swung can be according to specific
Situation.
Driving member 211 includes being fixed on the Left Drive portion of backrest 21 and right driving section, and Left Drive portion is provided with what is extended to the right
