Description

A kind of solar electric torch

Technical field

The utility model belongs to technical field of solar energy utilization, particularly relates to a kind of solar electric torch.

Background technology

The utilization of solar energy is a kind of technology of having a bright future.But the product variety of solar illumination apparatus is also few, particularly the solar electric torch kind also very little, and the manufacturing cost of existing product is higher.

Summary of the invention

For a kind of solar electric torch is provided to society, overcome the existing product defect of high cost, the utility model proposes following technical scheme.

A kind of solar electric torch comprises: pedestal, lucite cover cap, front panel, light emitting diode, and switch, rechargeable battery, positive plate, negative plate, solar cell, printed substrate, circuit, line is characterized in that:

Described pedestal is at its bottom viscose glue fixed solar battery; In the sidewall locations of pedestal, insert floatless switch, the switch installing hole is arranged on the described sidewall; In the sidewall locations of pedestal, insert fixedly negative plate, on the described sidewall outlet structure is arranged; At another sidewall of pedestal, insert fixedly positive plate, on the described sidewall outlet structure is arranged; In the forward position of pedestal, front panel, printed substrate and pedestal three fixedly are spirally connected successively, weld fixedly light emitting diode on the printed circuit board (PCB), and the round end of light emitting diode partly places the circular hole of front panel; Upper position at pedestal, lucite cover cap and pedestal are rotationally connected, described be rotationally connected be the small column that covers of plexiglass tent by in the circular hole that is inserted in pedestal sidewall rear portion, described small column is two small columns of lucite cover cap bending part projection.

The beneficial effects of the utility model are: provide a kind of solar electric torch to society, the low cost of manufacture of product is suitable for producing in enormous quantities.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The specific embodiment

In the utility model device, cover cap adopts colourless transparent resin glass to make.The colourless transparent resin glass cover cap, the one, can prevent dust, anti-gray etc.; The 2nd, can allow sunlight see through cover cap, be radiated on the solar cell E1.On the two side bending parts at lucite cover cap 1 rear portion, a columniform projection is arranged respectively, shown in the dashed circle among Fig. 1, columniform projection snaps in the circular hole of pedestal 2, just can realize being rotationally connected between lucite cover cap 1 and the pedestal 2.Light emitting diode D2, promptly illuminating lamp adopts the LED light emitting diode.Positive plate 3 and negative plate 6 are realized rechargeable battery E2 to be connected with other circuit by line.Solar cell E1, just usually said solar monocrystalline silicon, its function and effect are that the solar energy that receives is converted to electric energy.Can arrange, weld electronic element, circuit, line on the printed substrate 4.

Pedestal 2 can adopt the working of plastics that is processed by mold injects.Thereby the low cost of manufacture of product, be suitable for producing in enormous quantities.Pedestal 2 is as working of plastics, in design with when producing, all considered and arranged the mounting structure, the planarization at solar cell E1 viscose glue place, the installing hole of K switch or the like of insert structure, printed substrate 4 and front panel 5 of rotation circular hole, positive plate 3 and the negative plate 6 of lucite cover cap 1.

The middle position of pedestal 2 bottoms is smooth, smooth, uses viscose glue that solar cell E1 and pedestal 2 are achieved a fixed connection.

On a sidewall of pedestal 2, have the rectangle installing hole, because installing hole is dimensioned to close-fitting cause and K switch has the cause (as shown in Figure 1) of automatic expansion structure, after K switch is firmly advanced in the installing hole, K switch fixed-site not only, and be difficult to take out again.Because before K switch is pushed into installing hole, the plastic sheet of K switch two sides is open, be pushed in the process of installing hole in K switch, plastic sheet is extruded and closes up, after K switch is pushed into installing hole, plastic sheet loses the compressing of sidewall, can automatically spring open again, is difficult on the sidewall take out thereby K switch is stuck in.

Outlet structure place at pedestal 2 sidewalls firmly inserts negative plate 6, owing to calculate through accurate in advance, the tight size of outlet structure can guarantee: the negative plate 6 that firmly inserts, can be firm be in the outlet structure.Outlet structure and pedestal 2 main bodys connect together, and in injection moulding was produced, outlet structure and pedestal 2 main bodys were carried out injection moulding in the lump and finished.Same reason at another sidewall of pedestal 2, is inserted fixedly positive plate 3.

In the front portion of pedestal 2, screw passes front panel 5, printed substrate 4, is screwed into pedestal 2, and front panel 5, printed substrate 4, pedestal 2 threes fixedly are spirally connected successively.

Light emitting diode D2 is welded on the printed circuit board (PCB) 4.The round end position of light emitting diode D2 places in the middle of the circular hole of front panel 5.In the accompanying drawing of this specification, Fig. 1 and Fig. 2 be as illustrative nature, 3 the light emitting diode D2 that only draw, and in the actual product, light emitting diode D2 can be a plurality of, can also be many rows.

K switch is connected, can be charged or light a lamp.The transparent cover that can close charges, and also can open transparent cover and charge.If do not consider factors such as rainproof, purely from the performance of opto-electronic conversion, opening the transparent cover charging effect can be better.

In the time of charging, shine sunlight on the solar cell E1, produce electric energy,, electric energy is delivered to rechargeable battery E2 carry out energy storage by circuit and line.In illumination time,, rechargeable battery E2 discharges electric energy, by line etc., lights light emitting diode D2.
