Thus, when the exhaust pipe is opened, the rotating shaft 73 rotates more quickly under the action of the force of the spring 74 and the pushing force of the pushing plate 112, so that the exhaust pipe can be opened more smoothly, and the opening of the exhaust pipe cannot be influenced due to insufficient pushing force.

Wherein, the surface of the push plate 112 contacted with the deflector rod 72 is an inclined surface 1121. When the push plate 112 is pushed forward, the deflector rod 72 contacts with the inclined surface 1121, so that the deflector rod 72 relatively moves towards the inclined surface 1121, and the deflector rod 72 is extruded to move upwards, so that the rotary shaft 73 is driven to rotate outwards, the exhaust pipe is unfolded outwards, and when the push plate 112 moves backwards, the deflector rod 72 moves downwards towards the inclined surface 1121, the rotary shaft 73 is driven to rotate inwards, and the exhaust pipe is contracted inwards.

Specifically, the exhaust pipe 9 includes a first exhaust pipe 91 and a second exhaust pipe 92, the first exhaust pipe 91 and the second exhaust pipe 92 are connected to the exhaust pipe opening mechanism 7, respectively, and the first exhaust pipe 91 and the second exhaust pipe 92 are symmetrically disposed along the vehicle body center line. When the toy car is opened, the exhaust pipe looks like a pair of opened wings, so that the toy car is more unique in shape, attractive to consumers and interesting in the toy car.

More specifically, the first exhaust pipe 91 and the second exhaust pipe 92 are contracted to form a shell of the vehicle body, and the first exhaust pipe 91 and the second exhaust pipe 92 are contracted to form a shell of the vehicle body and are covered on the upper end of the doll 113. Thus, the shape of the contracted car body 12 is not affected, the attractive appearance of the car body can be ensured, more playability can be realized, and the interestingness of the toy car is improved.

As a further improvement of the present embodiment, the front vehicle body 11 is provided with front wheels, the rear vehicle body 12 is provided with rear wheels 122, the bottom of the rear vehicle body 12 is further provided with a second driving device and a driving wheel 17, the second driving device is connected with the driving wheel 17, and the bottom surfaces of the front wheels, the rear wheels 122 and the driving wheel 17 are in the same horizontal plane. The driving wheel 17 is driven to operate by the second driving device, so that the deformed toy car can move forwards or backwards, and the function of the toy car is realized more completely.

Specifically, a battery compartment 16 for mounting a battery is provided at the bottom of the vehicle body, and the battery compartment 16 is electrically connected to the first driving device, the second driving device, and the third driving device 8 at the same time.

The foregoing is a further detailed description of the application in connection with specific embodiments, and it is not intended that the application be limited to such description. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the application, and these should be considered to be within the scope of the application.
