Abstract
The utility model discloses a handheld terminal protective housing with stand -by power supply, including last casing and lower casing, should go up the casing and pass through buckle fixed connection with lower casing, the internal battery of series connection, wireless module and the rectifier circuit of charging of being provided with of epitheca, the inferior valve is internal to be provided with from the handheld terminal patch cord that charges that the interface drew forth that charges, and the patch cord that should charge is connected to rectifier circuit's output. This protective housing has increased handheld terminal time of endurance, improves the convenience that charges.
Description
Technical field
The utility model relates to technical field of mobile terminals, particularly relates to a kind of handheld terminal containment vessel.
Background technology
In prior art, for increasing handheld terminal battery life, usually in handheld terminal shell, add one piece of stand-by power supply.Such as, disclose a kind of rechargeable type handheld terminal protective sleeve in Chinese utility model CN201520056499.8, this protective sleeve adds stand-by power supply and handheld terminal charging end splicing ear and embedded charging wire rising in protective housing.
Conveniently charge; the technical scheme wired charging device being converted into wireless charging device is had in prior art; such as, disclose a kind of handheld terminal containment vessel that can realize wireless charging in utility model CN201420656152.2, reached by rectification circuit and make wired charging handheld terminal become wireless charging handheld terminal.
In these two kinds of containment vessels; the first rechargeable type handheld terminal protective sleeve; owing to only adding one piece of stand-by power supply in a protective case; and adopt displacement type terminal to be connected with handheld terminal end; then repeatedly winding displacement easily fractures, damages after dismounting, the situation such as loose contact occurs, and thus can not realize good and practicality reliably.In addition, in this rechargeable type handheld terminal protective sleeve, its embedded charging wire is subject to length restriction, and repeatedly uses, and may cause fractureing being short-circuited, thus can not realize good and stable practicality after bending.The second only changes the charging modes of handheld terminal, does not provide stand-by power supply, cannot reach and extend handheld terminal continuation of the journey function.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of.
Above-mentioned purpose is realized by following proposal:
With a handheld terminal containment vessel for stand-by power supply, it is characterized in that, described containment vessel comprises upper shell and lower house, this upper shell and lower house connection fixed by snap; The battery, wireless charging module and the rectification circuit that are connected in series is provided with in described upper shell; Be provided with the electricity charging switching wire of drawing from handheld terminal charging inlet in described lower house, this electricity charging switching wire is connected to the output of described rectification circuit.
According to above-mentioned containment vessel, it is characterized in that there is metallic radiating layer in described battery, wireless charging module and described rectification circuit surface coverage.
According to above-mentioned containment vessel, it is characterized in that, described metallic radiating layer is the metallic radiating layer being provided with louvre.
According to above-mentioned containment vessel, it is characterized in that, one end of described electricity charging switching wire adopts the charging adapter mated with described handheld terminal charging inlet, and what other end employing was mated with the output of described rectification circuit supplies electric adaptor.
According to above-mentioned containment vessel, it is characterized in that, the output of described rectification circuit is copper post.
According to above-mentioned containment vessel, it is characterized in that, described upper shell is connected by snap with lower house.
The beneficial effects of the utility model:
1, add handheld terminal cruising time, improve charging convenience, the portable power source that market exists compared by this handheld terminal protective sleeve, and to have volume little, and outward appearance is beautiful, lightweight, feature easy to carry.
2, the equipment utilizing wireless magnetoelectric induction to charge can accomplish that reducing charger is connected number of times with mobile phone, and equipment attrition rate is low, applied range.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit diagram of the present utility model.
Embodiment
See Fig. 1, handheld terminal containment vessel upper shell 1 of the present utility model and lower house 2, upper shell 1 and lower house 2 connection fixed by snap.The battery 3 of series connection, wireless charging module 4 and rectification circuit 7 is provided with in upper shell 1.
Be provided with the electricity charging switching wire of drawing from handheld terminal charging inlet in lower house 2, the other end of this electricity charging switching wire is connected with the output 6 of rectification circuit 7.One end of electricity charging switching wire uses the charging adapter 5 mated with handheld terminal charging inlet, the other end uses the adapter mated with output 6 (being preferably copper post) to be connected for electric adaptor 8 (the socket female of preferably mating with copper post), and both connections are positioned at the buckle junction of upper half-shell 1 and housing lower half 2.
In order to better heat radiation, there is metallic radiating layer in battery 3, wireless charging module 4 and described rectification circuit 7 surface coverage, preferably adopt the metallic radiating layer being provided with louvre.
See Fig. 2, rectification circuit 7 is connected with battery 3, wireless charging module 4, handheld terminal charging inlet, and the induced current for battery, wireless charging module being generated is rectified into the rated charge stream of handheld terminal.When user does not carry charger, can pass through stand-by power supply (battery 3) and charge, after stand-by power supply electricity (battery 3) exhausts, the mode of available wireless charging is charged, and greatly facilitates the use of user.
