Preferably, the gear set further comprises a worm fixed on the output shaft of the motor and a worm wheel coaxially and fixedly connected with the incomplete gear, and the outer diameter of the worm wheel is larger than that of the incomplete gear. The transmission mechanism of the worm and the worm wheel has a great transmission ratio, so that the structure of the whole gear set can be simplified as far as possible on the premise of ensuring the transmission ratio which is large enough.

Preferably, the housing is provided with a switch and a charging port for charging a power supply.

Preferably, the lower end of the rack is provided with a rubber block, and the rubber block can increase the friction force between the rack and the ground, reduce the phenomenon of skidding on the ground and improve the overall bouncing effect.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. the utility model drives the gear set to operate through the motor, so that the gear set drives the rack to move towards one side of the compression spring, the kinetic energy of the motor is converted into the elastic potential energy of the compression spring, and finally, the elastic potential energy is released at one time to form the bouncing effect; 2. the casing be oval or for the egg shape, the bottom of casing is equipped with the balancing weight, makes the toy has the effect of tumbler, can let the rack independently return to just like this.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Example 1: referring to fig. 1, 2 and 3, the bouncing toy comprises a shell 10 and a rack 20 vertically inserted in the shell in a sliding manner, wherein a pressure spring 30 is connected between the rack and the shell; the toy also comprises a gear set 40, a motor 50 and a power supply 60 which are arranged in the shell, wherein the gear set comprises a defective gear 41 which can be meshed with the rack, the upper part area of the circumference of the defective gear is arranged without teeth, and the motor drives the gear set to run, so that the defective gear drives the rack to move to one side of the extrusion compression spring; when the toothless area on the incomplete gear rotates to be in contact with the rack, the rack loses the gear tooth spacing on the incomplete gear, the pressure spring can push the rack to slide downwards quickly, and after the lower end of the rack is in contact with the ground, the reaction force on the ground enables the whole toy to jump off the ground. In the embodiment, the kinetic energy of the motor is converted into the elastic potential energy of the pressure spring through the gear set, and the elastic potential energy is released at last for one time to form a bouncing effect.

As shown in figure 1, the shell is egg-shaped, the bottom of the shell is provided with a balancing weight 11, the positions of the motor and the power supply are also reduced as much as possible, the center of gravity of the whole body is reduced as much as possible, and the toy has the effect of a tumbler. Therefore, the rack can automatically return to the right state and keep the vertical state, the rack is ensured to be opposite to the bottom surface in the next bounce, and the best bounce effect is ensured.

Referring to fig. 1 and 4, a vertically arranged chute 12 is arranged in the shell, the rack is in sliding fit in the chute, the cross section of the rack is in a T shape, and the chute is used for limiting the rack and better meshing with the incomplete gear; the upper end of the rack is provided with a limiting block 21 which can be abutted with the sliding groove downwards, the limiting block always limits the rack in an interval meshed with the incomplete gear, and therefore the rack can be limited by the limiting block after being pushed by the pressure spring, the incomplete gear can be meshed with the incomplete gear for transmission again, and the continuous bouncing effect is achieved.

Referring to fig. 3, the gear set further includes a worm 42 fixed on the output shaft of the motor, and a worm wheel 43 coaxially fixed with the incomplete gear, and the outer diameter of the worm wheel is larger than that of the incomplete gear. The transmission mechanism of the worm and the worm wheel has a great transmission ratio, so that the structure of the whole gear set can be simplified as far as possible on the premise of ensuring the transmission ratio which is large enough.

Referring to fig. 1, the housing is provided with a switch 70 and a charging port 80 for charging the power source.
