Abstract

The utility model provides a device for preventing a vehicle for children from sliding backwards. The device comprises a gear box device connected with wheels and a circuit board for electrically starting the gear box device. The gear box device comprises a gear box lower casing and a gear box upper casing. The gear box lower casing is provided with a relay, a motor and an axle hole for a magnetic axle equipped on the relay to pass through. The relay and the motor are respectively electrically connected with the circuit board which is applied for controlling the relay and the motor to be on or off. The gear box upper casing is provided with an upper casing hollow chamber inside which a gear set is equipped. The gear set is provided with a plurality of through holes each of which is respectively corresponding to the axle hole. When power is off, the magnetic axle passes through the axle hole until the magnetic axle is correspondingly inserted into the through hole of a first gear in the gear set. The first gear is then prevented from rotating. When power is on, the magnetic axle is attracted out of the through hole of the first gear and back into the relay. The first gear is then made in a freely rotating state. Therefore, the aim of braking an electric simulation automobile is achieved.

Background technology

On the current market, supply the of a great variety of carriage for children that children play, emulation car model or foot-operated bicycle etc. are arranged; More appearance be electrically operated emulation automobile toy, utilize motor cooperative mechanical device drives perambulator, when making children sit on it; The bearing circle that swings can make the front-wheel of automobile toy swing, through the energising of motor; Make automobile toy can go up the back side-to-side movement, the imitative as real car on the way walking, to one of the children enjoyment of driving really.

Though electrically operated emulation automobile toy brings joy for children,, still there are not minor defect and danger, at first because automobile toy is provided with four mobilizable wheels; Children are sitting in when top, have unfixed phenomenon, particularly two or three years old; Just understood the children that walk, they like the edge of two hand steered chairs to stand or walk, but when automobile toy occurs; Children are if holding up the edge of automobile toy to walk, and the four wheels of automobile toy can't be fixed, and is holding up its edge to roll; Therefore the danger that appearance is fallen, need big people keeping attention highly constantly, protecting from the side.

Moreover; When electrically operated emulation automobile toy is driven to half way up the mountain or slope by children, if occur having a power failure when perhaps drive motor does not rotate, after car will carry children's slide; Consequence is abnormally dangerous; Therefore, for electrically operated emulation automobile toy is provided with brake equipment, be lots of manufacturers' problems extremely to be solved.

Summary of the invention

The purpose of the utility model is to electrically operated emulation automobile toy is provided with brake equipment, realizes that automobile toy is having a power failure or motor when stopping operating, and phenomenon after the slide of car body is avoided in braking in time.

Therefore; The utility model comprises ripple case apparatus that connects wheel and the circuit card that supplies this ripple case apparatus electric control starting, and said ripple case apparatus is respectively equipped with ripple case lower casing and ripple case upper casing, wherein; Said ripple case lower casing is provided with relay, motor and supplies the axis hole that magnetic axis passes on this relay; The circuit card that said relay and motor are electrically connected this relay of control, motor unlatching respectively or close, said ripple case upper casing is provided with the upper casing cavity, in this upper casing cavity gear cluster is installed; Said gear cluster is provided with several perforation, and each perforation can correspond respectively to said axis hole.

Wherein, said gear cluster includes first gear, second gear and the 3rd gear, is to be provided with said perforation on said first gear.

Said first gear is to be axis rotation, the teeth on this first gear and the gear mesh of motor.

Said first gear has the double-layer gear of canine tooth and little tooth; Said second gear has the double-layer gear of canine tooth and little tooth; Said the 3rd gear has the double-layer gear of canine tooth and little tooth; The little tooth of wherein said first gear meshes the canine tooth of second gear, and the little tooth of said second gear meshes the canine tooth of the 3rd gear.

The beneficial effect of the utility model is that ripple case lower casing is provided with relay, motor with supply the axis hole that magnetic axis passes on this relay, and relay is electrically connected the circuit board type of controlling its unlatching or cutting out respectively with motor; So relay utilization energising magnetic principle is when having a power failure; Make this magnetic axis through axis hole until with the corresponding insertion of perforation of first gear of gear cluster; Realize the effect that blocking first gear rotates, when energising, magnetic axis then can pick up from the perforation of first gear and be returned in the relay; Make first gear be in free rotary state, can realize braking purpose the electric artificial automobile.

The specific embodiment

See also Fig. 1, the preferred embodiment that goes out the utility model shown in Figure 2; The utility model comprises ripple case apparatus 1 that connects wheel and the circuit card 2 that supplies this ripple case apparatus 1 electric control starting; Said ripple case apparatus 1 is respectively equipped with ripple case lower casing 11 and ripple case upper casing 12; Wherein, said ripple case lower casing 11 is provided with relay 13, motor 14 and supplies the axis hole 131 that magnetic axis 130 passes on this relay 13, and said relay 13 is electrically connected the circuit card 2 of controlling this relay 13, motor 14 unlatchings or cutting out respectively with motor 14; Said ripple case upper casing 12 is provided with upper casing cavity 121; In this upper casing cavity 121 gear cluster 3 is installed, said gear cluster 3 is provided with several perforation 331, and each perforation 331 can correspond respectively to said axis hole 131.

Said gear cluster 3 includes first gear 31, second gear 32 and the 3rd gear 33; Be to be provided with said perforation 331 on said first gear 31; Said first gear 31 has the double-layer gear of canine tooth and little tooth, and said second gear 32 has the double-layer gear of canine tooth and little tooth, and said the 3rd gear 33 has the double-layer gear of canine tooth and little tooth; The little tooth of wherein said first gear 31 meshes the canine tooth of second gear 32, and the little tooth of said second gear 32 meshes the canine tooth of the 3rd gear 33.Again, said first gear 31 is to be axis rotation, the teeth on this first gear 31 and the gear mesh of motor 14.
