Abstract

The utility model relates to a change-over switch for children electric vehicles, which comprises a switch bottom plate and a slide component which is provided with the switch bottom plate in a slide mode, wherein a slide contact sheet is arranged on the slide component, one pair of first static contact sheets and one pair of second static contact sheets are fixed on the switch bottom plate, and the slide contact sheet has three operating positions. The slide contact sheet slides between the first static contact sheets and the second static contact sheets, so the slide contact sheet is ensured to only contact with one pair of static contact sheets at most, and the slide contact sheet only has three working positions. The use is safe.

Description

The change over switch of children's electric motor vehicle

Technical field

The utility model relates to a kind of change over switch of children's electric motor vehicle.

Background technology

In the prior art, change over switch on the children's electric motor vehicle is normally realized the multiple motion state of electric motor car together by two or more switch combinations, for example advance at utmost speed, low-speed forward, stop etc., switch is welded together if wherein advance at utmost speed, this moment is when pressing the low-speed forward switch, motor with reception advance at utmost speed, two kinds of signals of low-speed forward, have unsafe hidden danger.

Summary of the invention

The utility model purpose provides a kind of change over switch of children's electric motor vehicle, can guarantee that children's electric motor vehicle changes under multiple motion state reliably.

For achieving the above object, the technical solution adopted in the utility model is: a kind of change over switch of children's electric motor vehicle, comprise switch baseplate, it also comprises the sliding part that slides mutually and be provided with described switch baseplate, has the slip contact on the described sliding part, be fixed with a pair of first static contact and a pair of second static contact on the described switch baseplate, described slip contact has three service positions, first service position is that described slip contact contacts with described two first static contacts, two first static contacts are conducted, and two second static contacts disconnect mutually; Second service position is that described slip contact contacts with described two second static contacts, and two second static contacts are conducted, and two first static contacts disconnect mutually; The 3rd service position be described slip contact between first static contact and second static contact, two first static contacts disconnect mutually, two second static contacts also disconnect mutually.

Because technique scheme utilization, the utility model compared with prior art has following advantage: because described slip contact slides between first static contact and second static contact, therefore guarantee that the slip contact can only be at most contacts with a pair of static contact wherein, therefore switch has only three service positions, and is safe and reliable.

Embodiment

Shown in each accompanying drawing, a kind of change over switch of children's electric motor vehicle, comprise switch baseplate 1, it also comprises the sliding part 9 that slides mutually and be provided with described switch baseplate 1, has slip contact 3 on the described sliding part 9, be fixed with a pair of first static contact 2 on the described switch baseplate 1 at intervals, a pair of second static contact 13, described slip contact 3 slides between described a pair of first static contact 2 and a pair of second static contact 13, has guide 4 on the described switch baseplate 1, have gathering sill 5 on the described slide block 6, described gathering sill 5 matches with described guide 4, makes slide block 6 to slide on guide 4.Have groove 14 on described slip contact 3, described guide 4 is positioned at groove 14.Have location notch 8 on the described slide block 6, described slip contact 3 is positioned at described location notch 8, and location notch 8 is used for the track that limit slippage contact 3 moves up and down, and is provided with spring 7 between described slide block 6 and the described slip contact 3.

As shown in Figure 5, described sliding part 9 is connected with operating grip 11 relative fixed by connector 12, and described operating grip 11 is slidingly arranged on the fixed disk 10, and described fixed disk 10 is fixedly connected with the car body of children's electric motor vehicle.Described a pair of first static contact 2 is electrically connected with the logic control circuit of controlling electric motor car respectively with a pair of second static contact 13.

When the described operating grip 11 of operation, thereby the slip contact 3 on the sliding part 9 is slided between two pairs of static contacts, described slip contact 3 has three service positions, as shown in Figure 4, first service position is that described slip contact 3 contacts with described two first static contacts 2, this moment, two first static contacts 2 were conducted, and two second static contacts 13 disconnect mutually, and children's electric motor vehicle advances at utmost speed; As shown in Figure 3, second service position is that described slip contact 3 contacts with described two second static contacts 13, and this moment, two second static contacts 13 were conducted, and two first static contacts 2 disconnect the children's electric motor vehicle low-speed forward mutually; As shown in Figure 2, the 3rd service position be described slip contact 3 between first static contact 2 and second static contact 13, this moment, two first static contacts 2 disconnected mutually, two second static contacts 13 are disconnections mutually also, children's electric motor vehicle stops.
