Embodiment
In order more clearly to explain the present invention, below in conjunction with accompanying drawing, the present invention is further described.
Refer to Fig. 1-3, the invention provides a kind of back splint power switch device, comprise the button 1 suitable with the volume key of mobile phone, soft pcb board 2 and protective layer 3; Button 1 is positioned at the outside of back splint power supply, and soft pcb board 2 is fixed on the inner side of button 1, and protective layer 3 is fixed on soft pcb board 2 inner sides; Soft pcb board 2 is provided with thin film switch and switching circuit, and thin film switch is between button 1 and mobile phone volume key, and thin film switch is electrically connected with back splint power supply by switching circuit; Button 1 comprise with mobile phone add the first suitable button 11 of volume key and with suitable the second button 12 of the Att key of mobile phone; The first button 11 is suitable with thin film switch; On soft pcb board 2, be also provided with display circuit and LED lamp, LED lamp is electrically connected with back splint power supply by display circuit, and LED lamp is positioned at the second button 12 inner sides.
Compared to prior art, back splint power switch device provided by the invention, button 1 is suitable with the volume key of mobile phone, has applied the back splint power supply of this back splint power switch device, consistent with phone housing in appearance, has advantages of elegant in appearance, good hand touch.Button 1 is by thin film switch and switching circuit, realize the function of the switch of controlling back splint power supply, length started to charge by 3 seconds, length stopped charging by 3 seconds again, this button 1 is only pressed the function that could realize the switch of controlling back splint power supply by length, in the time clicking, realization be the function of mobile phone volume key, be that back splint power switch device of the present invention is not affecting under the prerequisite of mobile phone volume key normal usage function, realize the function of the switch of controlling back splint power supply.Back splint power switch device of the present invention has with mobile phone suitable, simple in structure, easy to operate advantage.
With mobile phone add the first suitable button 11 of volume key for controlling the switch of back splint power supply, the LED lamp under the second button 12 is for showing the dump energy of back splint power supply.Back splint power switch device provided by the invention not only has the function of the switch of controlling back splint power supply, can also show the dump energy of back splint power supply, can remind user in time for back splint power source charges, and rationally use back splint power supply according to dump energy, make the use of back splint power supply more convenient.
LED lamp has the method for the dump energy of following two kinds of demonstration back splint power supplys at least:
The first, LED lamp shows the dump energy of back splint power supply by different flicker forms, long bright expression back splint power supply also has the electric weight of 96-100%, flicker single represents that back splint power supply also has the electric weight of 76-95% continuously, 2 expression back splint power supplys of flicker also have the electric weight of 51-75% continuously, continuously 3 expression back splint power supplys of flicker also have the electric weight of 26-50%, and 4 the expression back splint power supplys of glimmering continuously also have the electric weight of 1-25%.
The second, LED lamp shows the dump energy of back splint power supply by the light of different colours, LED lamp sends green glow and represents that back splint power supply also has the electric weight of 96-100%, LED lamp sends purple light and represents that back splint power supply also has the electric weight of 76-95%, LED lamp sends blue light and represents that back splint power supply also has the electric weight of 51-75%, LED lamp sends gold-tinted and represents that back splint power supply also has the electric weight of 26-50%, and LED lamp sends ruddiness and represents that back splint power supply also has the electric weight of 1-25%.
Certainly, this is only two specific embodiments of the present invention, and LED lamp of the present invention shows that the method for the dump energy of back splint power supply is not limited in this, also can combine two kinds of methods to show.
Back splint power switch device provided by the invention, button 1 is the button of PC material.Button 1 adopts PC material to manufacture right advantage and is: PC material fatigue resistance is high, long service life; The hardness of PC material is moderate, good hand touch; PC material is more common material, and material source is wide, and cost is low, can reduce the production cost of back splint power switch device.Certainly this is only a specific embodiment of the present invention, and button 1 material of the present invention is not limited in PC, can be also the other materials that fatigue resistance is high.
In addition, the present invention also provides a kind of manufacturing process of button, comprises following step:
Step 1, take transparent PC as raw material, the disposable button 1 that is provided with the first button 11 and the second button 12 that is injection molded into; Step 2, evenly sprays paint at the outer surface of button 1; Step 3, utilizes laser engraving equipment, by the second button 12 part engraving transparences.
Disposal molding injection moulding makes the each several part mechanical property of button 1 uniform and stable, and production cost is low; Outer surface to button 1 evenly sprays paint, and can make button 1 have good corrosion resistance, and more attractive in appearance; Laser engraving equipment only carries out laser engraving to the second button 12 parts, makes the second button 12 have good light transmission, avoids unnecessary processing, reduces production costs.
In the present embodiment, the paint color that the outer surface of button 1 sprays is identical with the color of back splint power supply.Such design can not affect the attractive in appearance of back splint power supply.
Disclosed is above only several specific embodiment of the present invention, but the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
