The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The embodiment of the invention provides a kind of mobile terminals, and as depicted in figs. 1 and 2, respectively the embodiment of the present invention provides
A kind of mobile terminal positive structure schematic and cross section structure schematic diagram.
With reference to Fig. 1 and Fig. 2, which includes: the accessories such as center 11, rear shell 12, mainboard 13, display screen 17 and earpiece
18, in which:
It is arranged fluted 14 close to the side of rear shell 12 in center 11, is provided in groove 14 by fiber optic emitter 151, light
The optical fibre device 15 that fine receiver 152 and conduction optical fiber 153 form, is electrically connected between optical fibre device 15 and mainboard 13；
Optical fibre device 15, which is configured to fiber optic emitter 151, to be believed by conduction optical fiber 153 to 152 launching fiber of fiber optic receiver
Number；
Mainboard 13 is configured to whether fiber-optic signal can be received by detection fiber receiver 152, to judge mobile terminal
Whether intake.
Wherein, groove 14 can be directly molded by mold, and mobile terminal is when being assembled by optical fibre device 15
It is directly mounted in groove 14, can be fixed in groove 14 using double-sided adhesive mode, mounting means is simple and easy.
Specifically, when optical fibre device 15 is mounted in groove 14, it can be by fiber optic emitter 151 and fiber optic receiver
152 are arranged in the groove 14 at 11 4 angles of center, and conduction optical fiber 153 is arranged in the groove 14 of four sides of center 11
It is interior.
This optical fibre device 15 is distributed in the mode of the peripheral position of mobile terminal, it can be achieved that any position in mobile terminal periphery
The water inlet detection set, detection effect are good.
Why above-mentioned this structure can be realized the water inlet detection of mobile terminal, and used principle is based on optical fiber knot
The total reflection principle of structure.It is well known that refraction angle is greater than incidence when fiber-optic signal is incident on optically thinner medium by optically denser medium
Angle, as 1 > arcsin (sin θ 2*n2/n1) of incidence angle θ, fiber-optic signal is totally reflected, as shown in Figure 3.
Mobile terminal provided by the embodiment of the present application is based on this principle and designs, and is set by the center in mobile terminal
Groove is set, in the quadrangle of groove and four side built-in fiber transmitters, conduction optical fiber and fiber optic emitter, whether is detection complete machine edge
There is the entrance of the liquid such as water, the fiber-optic signal that fiber optic emitter is sent when water inlet is projected and can not be received by fiber optic receiver, from
And realize the function of water inlet detection.
As shown in figure 4, for mobile terminal without water inlet state when fiber-optic signal propagate schematic diagram.Wherein, light is conducted at this time
When fibre is located in air, when fiber optic emitter by conduction optical fiber to fiber optic receiver launching fiber signal when, light signal meeting
It is all received by fiber optic receiver.
As shown in figure 5, fiber-optic signal when being mobile terminal water inlet state propagates schematic diagram.Wherein, conduction optical fiber is located at
In water, when fiber optic emitter by conduction optical fiber to fiber optic receiver launching fiber signal when, due to the refractive index and conduction of water
The refractive index difference very little of optical fiber, causes light signal that can not be received by fiber optic receiver.
In order to guarantee the total reflection in dielectric surface of fiber-optic signal, need to guarantee to conduct optical fiber 153 big using refractive index
In the transmission material of air refraction.
Optionally, conduction optical fiber 153 can be less than the transmission material of preset threshold using the difference of refractive index and water refractive index
Material.
That is, the refractive index of conduction optical fiber 153 and the refractive index of water are closer, mobile terminal water inlet more can guarantee
Efficient detection.
Optionally, conduction optical fiber 153 can use earth silicon material or fluorine resin material.

1 > arcsin of θ (1/n), n are the refractive index for conducting optical fiber 153.
Further, mobile terminal further includes power supply 16, in which:
Optical fibre device 15 and mainboard 13 are electrically connected between power supply 16, and power supply 16 is that mainboard 13 and optical fibre device 15 supply
Electricity, to guarantee that mobile terminal complete machine and optical fibre device work normally.
Mainboard 13 is configured to when detecting that fiber optic receiver 152 does not receive fiber-optic signal, cuts off the power 16.
Based on the same inventive concept, the embodiment of the invention also provides a kind of water inlet detection method of mobile terminal, such as Fig. 6
It is shown, it is a kind of flow diagram of the water inlet detection method of mobile terminal provided in an embodiment of the present invention.
This method comprises:
Step 61, whether mainboard real time monitoring fiber optic receiver receives fiber-optic signal；
Wherein, outside water is penetrated into the center 11 of mobile terminal from card slot or adhesive area, preferentially enters 11 periphery of center
Card slot, contact conduction optical fiber 153.
Conduction optical fiber 153 is contacted by the water, and due to the refractive index difference of very little between its material and water, fiber optic emitter 151 is sent out
The fiber-optic signal penetrated directly projects, and can not continue to be totally reflected and is received by the fiber optic receiver 152 of end, therefore, it is determined that for water inlet.
Step 62, it when mainboard, which monitors fiber optic receiver, does not receive fiber-optic signal, cuts off the power.
Under normal condition, power supply 16 is powered to mainboard 13, and driving machine system works normally and display, fiber optic emitter
151 moment sent fiber-optic signal into conduction optical fiber 153, and fiber-optic signal is all totally reflected and is sent to fiber optic receiver 152,
Determine that, without water inlet, 16 continued power of power supply, machine system works normally by mainboard 13 at this time；
When the water inlet of mobile terminal side, fiber optic receiver 152 can not normally receive the light that fiber optic emitter 151 is issued
Optical fiber signaling determines mobile terminal water inlet, system shutdown power supply, the member such as power supply and mainboard device after avoiding into water by mainboard 13 at this time
Part is damaged because of electrical shorts.
In addition, warning message, such as suggestion voice etc. can also be first issued before cutting off the power in addition to cutting off the power,
To prompt customer mobile terminal to intake.
