Description

The anti-back of a kind of perambulator slip device

Technical field

The present invention relates to the perambulator that children use, detailed is the anti-back of a kind of perambulator slip device, belongs to the ripple case brake field that is applied in perambulator.

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. arranged, more appearance be electrically operated emulation automobile toy; Utilize motor cooperative mechanical device drives perambulator; When making children sit thereon, the bearing circle that swings can make the front-wheel of automobile toy swing; Energising through 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; But; 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 occurred, children were if holding up the edge of automobile toy to walk, and the four wheels of automobile toy can't be fixed; Holding up its edge to roll; Therefore the danger that appearance is fallen, need big people keep the attention of height constantly; Protect 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 objective of the invention is to for electrically operated emulation automobile toy is provided with brake equipment, realize that automobile toy is having a power failure or motor when stopping operating, phenomenon after the slide of car body is avoided in braking in time.

Therefore; The present invention includes ripple case apparatus that connects wheel and the circuit card that supplies ripple case apparatus energising situation; 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 supply the axis hole that magnetic axis passes on this relay; The electric respectively logotype of said relay and motor is in connecing this relay of control and the unlatching of motor or the circuit card of closing; 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 be distinguished corresponding and 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.

Beneficial effect of the present invention is that ripple case lower casing is provided with relay; The axis hole that magnetic axis passes on motor and this relay of confession; And the circuit board type that relay and motor are electrically connected its unlatching of control respectively or close; So; Relay utilization energising magnetic principle; When having a power failure; Make this magnetic axis by axis hole until with the corresponding insertion of perforation of first gear of gear train; 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, makes first gear be in free rotary state, can realize the braking purpose to the electric artificial automobile.

Description of drawings

Fig. 1 is the block diagram of most preferred embodiment of the present invention.

Fig. 2 is the STRUCTURE DECOMPOSITION figure of Fig. 1.

The specific embodiment

See also Fig. 1, shown in Figure 2ly go out most preferred embodiment of the present invention, the present invention includes the ripple case apparatus 1 that connects wheel and be connected the switch on circuit card 2 of situation of ripple case apparatus 1, the alleged ripple case in the present technique scheme comes down to transmission gearbox.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; Said relay 13 is electrically connected control respectively with motor 14 and is used for the unlatching of this relay 13 and motor 14 or the circuit card 2 of cutting out; 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 be distinguished corresponding and 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; Said second gear 32 has the double-layer gear of canine tooth and little tooth; 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.

Therefore; By ripple case lower casing 11 and ripple case upper casing 12 to engaging; Constitute the ripple box main body; Be provided with magnetic axis 130 in the relay 13; This magnetic axis 130 has movable Telescopic, and when relay 13 energisings, the magnetic field that is produced by electric current sucks magnetic axis 130; When cutting off the power supply or not having electricity, relay 13 built-in spring handle magnetic axises 130 outwards eject.

Said circuit card 2 is to be the time delay relay circuit plate, can be external, and, be connected with relay 13 with motor 14 through lead 21, realize controlling and driving motor 14, and the energising situation of relay 13.

Therefore, whole ripple case is under out-of-run situation, and magnetic axis 130 is inserted in the perforation 331 of first gear 31 through axis hole 131 always, and each gear in the ripple case can not be rotated; And when ripple case energising work; It at first is relay 13 energising earlier; Magnetic axis 130 is sucked in the relay 13; The perforation 331 that makes magnetic axis 130 break away from first gear 31; At this moment; Circuit card 2 (time delay relay circuit plate) controlling and driving motor 14 again rerunned in slow one second, and motor 14 is through the gear change of first gear 31, second gear 32 and the 3rd gear 33 then, by the 3rd gear 33 power was sent out.

According to the above description, and combine accompanying drawing as better embodiment of the present invention, right, other equivalent embodiment of the present invention is not limited thereto, and understands by said practical implementation, and above-mentioned embodiment has disclosed concrete function of the present invention and behavior of structure.
