Abstract
The utility model relates to a mobile phone shell. The mobile phone shell comprises a shell body which can be in buckling connection with a mobile phone body. The mobile phone shell is characterized in that a heating thermal-insulation element which is corresponding to a portion where the mobile phone body is assembled with a lithium battery is arranged inside the shell body; a power-supplying power source which is connected with the heating thermal-insulation element is also arranged inside the shell body; and the power-supplying power source is connected with the heating thermal-insulation element so as to form an thermal-insulation heating loop. Compared with the prior art, and according to the mobile phone shell of the utility model, the heating thermal-insulation element is arranged inside the mobile phone shell body; the power-supplying battery supplies power for the heating thermal-insulation element; after emitting heat, the heating thermal-insulation element can heat the lithium battery which contacts with the heating thermal-insulation element, such that the temperature of the lithium battery can rise; and therefore, the lithium battery of the mobile phone can work under proper temperature, and the lithium battery can be protected, and the lithium battery is not prone to being damaged by over-low temperature.
Description
Technical field
The utility model relates to a kind of mobile phone shell.
Background technology
The phenomenon that the mobile phone electric weight drops to very low automatic shutdown suddenly can appear in the lower environment of temperature to such an extent as to overwhelming majority mobile phone is in, trace it to its cause, be because can not normal power supply when being lower than uniform temperature to the lithium battery of mobile phone power supply, the working temperature of lithium battery is-20 degrees centigrade～+ 60 degrees centigrade, after carrying it into indoor or warmer local a period of time afterwards, it is normal that the mobile phone electric weight recovers, but the infringement to battery of mobile phone is irrecoverable, that is to say the useful life that has shortened lithium battery greatly, this phenomenon is commonly called " mobile phone is afraid of cold " phenomenon.Such as in some areas of northeast China; temperature drops to subzero more than 20 degree in winter through regular meeting; what " mobile phone is afraid of cold " phenomenon also will occur under this environment is very frequent; if running into emergency or thing needs to handle; can often be perplexed by this phenomenon, bring a lot of unnecessary troubles for people's work, cause and life.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of mobile phone shell that can be incubated lithium battery at above-mentioned prior art under low temperature environment.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of mobile phone shell, comprise the housing that can be fastened and connected with mobile phone body, it is characterized in that: described enclosure interior is provided with the heat tracing element at the position corresponding with mobile phone body assembling lithium battery, and described enclosure interior also is provided with the power supply that is connected with the heat tracing element, and power supply and heat tracing element link together and constitute the insulation heating circuit.
Described housing is provided with part and exposes to the temperature-sensitive indicator light that housing is outer and contact with lithium battery in the mobile phone body, when the temperature of lithium battery was heated to a certain degree, variation had taken place in the color of temperature-sensitive indicator light, at this moment like this, just can close swap switch, stop lithium battery being heated.
Described heat tracing element comprises: heater strip or heating resistor, and the heat preservation hot conductive membranes that covers or wrap up heater strip or heating resistor.
Described power supply is that the low-temperature working temperature is lower than subzero 20 degrees centigrade supplying cell at least, and described housing is provided with the switch that is serially connected on the above-mentioned insulation heating circuit.
The amplifying circuit that described power supply also can adopt piezo chips and be connected with piezo chips.Because the electric current that can produce with the supporting piezo chips of mobile phone shell is very little, so adopts amplifying circuit to amplify, generating electricity no longer needs switch, need press the mobile phone shell rear portion can realize heating process.
Compared with prior art; advantage of the present utility model is: by in handset shell inside the heat tracing element being set; by supplying cell the heat tracing element is powered; can the lithium battery that be in contact with it be heated after the heat tracing element heating; thereby lithium battery is heated up; then ensureing that cellular li-ion battery is under the suitable temperature works, and has protected lithium battery like this, makes lithium battery be difficult for being damaged by low excessively temperature.

Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
Mobile phone shell shown in Fig. 1～4, comprise the housing 1 that can be fastened and connected with mobile phone body 7, this housing 1 inside is provided with the heat tracing element at the position corresponding with mobile phone body assembling lithium battery 8, the heat tracing element comprises heater strip 2, and cover the outer heat preservation hot conductive membranes of heater strip, the heat preservation hot conductive membranes is pellosil 4, for and housing 1 inside also be provided with and be connected with heater strip 2, the low-temperature working temperature is lower than subzero 20 degrees centigrade supplying cell 3 at least, supplying cell 3 can be selected No. 5 alkaline batteries or button cell or Ni-MH battery or nickel-cadmium cell, frivolous with volume is good, supplying cell 3 links together with heater strip 2 and constitutes the insulation heating circuit, and housing 1 is provided with the switch 5 that is serially connected on the above-mentioned insulation heating circuit.
In addition, housing 1 is provided with part and exposes to the temperature-sensitive indicator light 6 that housing is outer and contact with lithium battery in the mobile phone body.
When mobile phone environment of living in is on the low side when causing the lithium battery electric weight to descend rapidly, open switch 5, heater strip 2 is generated heat under the effect of supplying cell 3, thereby lithium battery is heated up, when the temperature of lithium battery rises to a certain degree, after the color of temperature-sensitive indicator light 6 changes, close swap switch 5 and get final product.
Embodiment two
Different with embodiment one, above-mentioned heater strip substitutes with three ceramic resistors are in parallel.
Embodiment three
Different with embodiment one is that heater strip directly is embedded in the pellosil 4.
Embodiment four
Different with embodiment one is, above-mentioned supplying cell 3 adopt piezo chips and the amplifying circuit that is connected with piezo chips alternative.Switch 5 no longer is set on the housing 1.During power supply, only need press piezo chips and can generate electricity.
