Description
Technical field
The present invention relates to mobile communication technology field, particularly to a kind of hand-held mobile terminal with touch function。
Background technology
Along with the arrival in 3G intelligence epoch, touch screen handheld terminal uses more and more general, and the application of range sensor also gets more and more。When user answers the call, range sensor will play its effect, and when the face of user is near screen, the screen lamp of mobile phone can extinguish, and locks screen automatically, and is so possible to prevent the face maloperation of user, and when user's face leaves, screen lamp can automatically turn on, and automatic unlocking。
Therefore the adjust the distance sensitivity requirement of sensor of touch screen handheld terminal is higher, range sensor from the distance of touch screen more than 5mm time, its performance will be produced large effect, range sensor nonfunctional when serious, can be caused to sense。
At present, when range sensor from touch screen distance more than 5.0mm time, performance in order to ensure range sensor, be typically between range sensor surface and touch screen increase light-guiding pillar carry out leaded light, as it is shown in figure 1, touch-screen mobile phone includes casing 101, touch screen 102, black silicon gum cover 103, range sensor 104, mainboard 105 and light-guiding pillar 106。Wherein, described touch screen 102 is arranged in casing 101, casing 101 and range sensor 104 are arranged on mainboard 105, between described range sensor 104 and touch screen 102, there is certain distance, light-guiding pillar 106 is between described range sensor 104 and touch screen 102, for leaded light, black silicon gum cover 103 is filled in the gap of range sensor 104 and casing 101。Above-mentioned touch screen handheld terminal is when the spacing of range sensor 104 and touch screen 102 is more than 5mm, guide-lighting by light-guiding pillar 106, it is ensured that the performance of range sensor 104。
But the energy of light is transmitted and has certain loss by light-guiding pillar, and owing to light-guiding pillar is to cooperate with part, processing technique and the rigging error of light-guiding pillar itself are all difficult to control to, light guide effect is made also to be difficult to keep consistent, the concordance eventually resulting in complete machine is poor, adds the debugging time of complete machine。

Fig. 2 is the cross section structure schematic diagram that the present invention has the hand-held mobile terminal of touch function。
Detailed description of the invention
The present invention provides a kind of hand-held mobile terminal with touch function, and for making the purpose of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
Referring to Fig. 2, it has the cross section structure schematic diagram of hand-held mobile terminal of touch function for the present invention。As shown in Figure 2, the hand-held mobile terminal with touch function provided by the invention includes casing 10, touch screen 20, range sensor 30, FPC40(FlexiblePrintedCircuit, flexible circuit board), ZIF(ZeroInsertionForce, zero tall and straight power) adapter 50, mainboard 60 and support 70。
Described touch screen 20 is installed in described casing 10, for accepting the touch information of user's input。Described range sensor 30 is arranged in described casing 10, and described casing 10 and range sensor 30 are arranged on described FPC40。Described FPC40 is arranged on described support 70, and is electrically connected with mainboard 60 by described ZIF connector 50。Described range sensor 30 is range sensor chip, and its dress is attached on FPC40, FPC40 electrically connected with mainboard 60 by ZIF connector 50, it is achieved the inducing function of range sensor 30。Wherein, described ZIF connector 50 can adopt the ZIF connector of 6PIN, and its plug is very convenient。
Present invention utilizes the motility of FPC, it is ensured that the effect of range sensor is optimum, meet the requirement less than 0.4mm of the range sensor end face distance with touch screen。When being embodied as, the position of range sensor 30 arbitrarily can adjust by changing the profile of FPC according to specific requirement, without being subject to the restriction of mainboard cloth member cabling。And, the cloth member on FPC40 can be flexible and changeable, it is also possible to arranges all the other devices, thus reducing the electronic component of required cloth member on mainboard 60, reduces the wiring space of mainboard。
Please continue to refer to Fig. 2, described support 70 is arranged on described mainboard 60, and described support 70 has for raising range sensor 30, makes the jut 701 of distance between range sensor 30 and touch screen 20。The present embodiment raises the height of range sensor 30 by FPC40 and support 70, and makes the distance between touch screen 20 and range sensor 30 less than 0.4mm, to strengthen the performance of range sensor 30。
In the specific implementation, described support 70 is the metal racks such as aluminum frame, copper stent, retort stand, and owing to the intensity of metal is better, support 70 can be made very thin, but also support 70 can be utilized to do electrostatic grounding and process。Certain support 70 can also adopt plastic rubber bracket, and the material of support 70 is not limited as by the present invention。
In order to raise range sensor 30, and increase FPC40 is placed on the stability on support 70, can directly be bent intoType, makes 701 one-tenth planes of described jut, has certain space in the lower section of jut 701。In order to save wiring space, on described mainboard 60, and the region 90 being positioned at the lower section of described jut 701 is provided with electronic device。
Please continue to refer to Fig. 2, the hand-held mobile terminal with touch function provided by the invention, the contact site of touch screen 20 and casing 10 is provided with foam 80, this foam 80 is used for bonding casing 10 and touch screen 20, make touch screen 20 more firm, and also serve and fall cushioning effect, it is prevented that hand-held mobile terminal is broken, and described foam 80 also acts to a certain extent and absorbs touch screen 20 LCD shows the interference of module。
In the embodiment of the present invention, the thickness of described foam 80 is less than 0.3mm, reduce the distance between touch screen 20 and range sensor 30 as far as possible, and the region of respective distances sensor 30 is provided with at least one through hole 801 on described foam 80, make foam 80 without influence on the performance of range sensor 30, thus increasing the stability of hand-held mobile terminal。Further, the quantity of through hole and size can be arranged as the case may be。
In sum, the present invention by being arranged on described FPC by range sensor, and FPC is arranged on the bracket, with the height of support, range sensor height is raised the distance reducing between range sensor and touch screen, make the stable performance of product, compared with the guide-lighting mode of existing employing light-guiding pillar, present invention eliminates two light-guiding pillars, decreasing the debugging time, the performance for product provides guarantee。
Simultaneously, range sensor is arranged on FPC, make the position of range sensor not by the restriction of pcb board wire location, assemble simple and convenient, and the jut of support also add the space of cloth member, electronic component is laid in below support, it is possible to reduce layout area and the price of pcb board, is conducive to product to develop to miniaturization。
It is understood that for those of ordinary skills, it is possible to it is equal to replacement according to technical scheme and inventive concept thereof or is changed, and all these are changed or replace the scope of the claims that all should belong to appended by the present invention。
