Description

A kind of electronic building blocks power supply device

Technical field

The utility model relates to electronic building blocks power supply devices, and in particular to a kind of electronic building blocks power supply device.

Background technique

The toy much used on the market about children at present, mechanical comparison is more, for electronic toy, than Less, what is both mechanically and electrically combined is less, and the basic unit both mechanically and electrically constituted is less, the use of the new type combination electronics And it is mechanical, design a novel electron toy.

Summary of the invention

The purpose of this utility model is to provide one kind can be with the electronic building blocks power supply device of flexible Application.

Electronic building blocks power supply device is made of components such as upper cover, lower cover, power knob, lithium battery, circuit boards, Yi Ji electricity It is constituted on the plate of road with external corresponding USB interface, four needle connection-pegs, USB interface, light-guiding pillar.

There is USB interface fluting before upper cover, is the interface of battery charging；Place next to USB interface is four needle grafting Mouthful, also there is identical four needles connection-peg on right side, they are collectively as signal input and output interfaces；Top is done in USB interface, there is square Deep gouge under shape, fixed power source switch；There is a circular aperture on the left of deep gouge under rectangle, is the circular hole of fixed light-guiding pillar, works as leaded light Column is bright and when not working, and indicates respectively this power supply just in out-put supply and not out-put supply；There are two boss for diagonally opposing corner inside upper cover Firmly, it is fixed by screw and lower cover nut bore, upper and lower covers is fixed as an entirety；Upper cover inner wall installs four needle sockets to side wall On have four uniform muscle, be fixing muscle on the right side of battery, with fixing muscle think in have certain distance also and have four reinforcing ribs, be Fixing muscle on the left of battery, they concur, and fixed battery prevents battery from loosening；There is recessed of annular respectively in product edge, It is that the recessed lip of upper cover and lower cover convex lip cooperate, so that product is loaded better button, facilitate installation.

Since product itself space limits, circuit board, which is done, forms " L " type by rectangular, and lithium electricity can just be put by lacking place Pond, there are two circular holes on circuit board, are just stuck on the cylinder of boss column.

Four needle interfaces, USB interface, switch key are directly welded on circuit board, constitute a small entirety.

When Product Assembly, first " L " type circuit board is put into lower cover, the screw via hole on circuit board is covered in lower cover nut bore On, then power supply is placed on circuit board notch, power switch set is covered on power supply at this time, upper cover is closed, when closing lid Notice that upper and lower covers lip is aligned, after closing, screw tightening is completed to assemble.

The beneficial effects of the utility model are:

Power supply device space layout is compact, and external interface is reasonable, meets and is used as the basic power demands of toy for children；

Power supply device can be used with recharge, environmentally protective.

Specific embodiment

Below with reference to illustrate attached drawing to the embodiments of the present invention further illustrate.

Four needle connection-pegs (3-2), power switch (3-4), USB interface (3-5), are directly welded at " L " at light-guiding pillar (3-3) On type circuit board, it is stuck on lower cover nut bore (4-1) by screw via hole (3-1)；It is put in the indentation, there of " L " type circuit board (3) Lithium battery (2) are set, when upper cover is detained, fixing muscle (1-5), battery right side fixing muscle (1-6) are fixed on the left of the battery of upper cover Lithium battery (2), prevents from shaking；Power switch set (6) covers on power switch (3-4), can be under rectangle when upper cover closes It reciprocatingly slides in deep gouge (1-1), controls power switch；Light-guiding pillar (3-3) is deep into light-guiding pillar light-conductive hole (1-2), when lamp is bright When can be with supplying power for outside, not supplying power for outside when not working；Upper and lower covers altogether when rely on the recessed lip of upper cover (1-7), lower cover convex lip respectively It is closed when (4-2) is aligned tightly, closes next with screw (5) that upper and lower covers are fixed tight, completion assembly.
