The utility model embodiment provides a kind of touch eyeglass fixed structure that conductive film is not fragile, the position of touch eyeglass on casing is more consistent with predefined ideal position on the eyeglass and portable terminal that is provided with this touch eyeglass fixed structure of touching.
As Fig. 4, Fig. 5 and shown in Figure 6, the touch eyeglass fixed structure that the utility model embodiment is provided comprises plastic material and is frame shape casing 1 and injection moulding as shown in Figure 5 metalwork 2 on casing 1 inwall as shown in Figure 4, wherein:
Touch in the eyeglass 3 as shown in Figure 6 that the top of glassy layer 31 is coated with conductive film 32, the bottom adhesive of glassy layer 31 is on metalwork 2 and/or casing 1;
Be installed with spacing preiection 5 on the inwall of casing 1, the position of spacing preiection 5 is between the bottom of conductive film 32 that touches eyeglass 3 and glassy layer 31.
Owing to be installed with spacing preiection 5 on the inwall of casing 1 provided by the utility model, spacing preiection 5 is between the bottom of conductive film 32 and glassy layer 31, when assembling touches eyeglass 3 on the utility model touch eyeglass fixed structure, after being sidelong one of touch eyeglass 3 approaching flexible print circuit boards 33 as shown in Figure 3 on the inwall that places casing 1, under the effect of gravity, the glassy layer 31 that touches in the eyeglass 3 can be pressed against on the spacing preiection 5, spacing preiection 5 withstands on the glassy layer 31 and touch eyeglass 3 can be supported, thereby can keep having enough gaps between glassy layer 31 and casing 1 inwall, and then the conductive film of avoiding touching eyeglass 3 32 is run into the inwall of casing 1 and is caused conductive film 32 to damage;
Simultaneously, the concrete size of spacing preiection 5 can be provided with according to the size that touches gap between eyeglass 3 and casing 1 inwall, uneven defective in gap when so spacing preiection 5 can also remedy casing 1 injection moulding between caused casing 1 inwall, guarantee that the gap that touches between eyeglass 3 and the casing 1 is more even, and then it is more consistent with predefined ideal position to guarantee to touch the position of eyeglass 3 on casing 1, exists the conductive film 32 that touches on the eyeglass 3 fragile so solved prior art, touch position and predefined ideal position the technical problem that deviation easily occur of eyeglass 3 on casing 1.
The conductive film 32 that touches on the eyeglass 3 is electrically connected with flexible print circuit board 33 as shown in Figure 3, and spacing preiection 5 is fixedly arranged on the inwall near the casing 1 of flexible print circuit board 33.
In this structure, there are enough spaces to guarantee that the flexible print circuit board 33 that is electrically connected with conductive film 32 on the touch eyeglass 3 can be smoothly from outlet between glassy layer 31 and casing 1 inwall between the inwall that spacing preiection 5 can guarantee casing 1 and the glassy layer 31.
The edge of metalwork 2 comprises and links to each other with the parallel portion as shown in Figure 6 21 of casing 1 plane parallel and with parallel portion 21 and have the kink 22 of angle with parallel portion 21 in the present embodiment, wherein:
Exist angle to be preferably 90 ° in the present embodiment between parallel portion 21 and the kink 22 between 60 °～100 °.Parallel portion 21 forms for same sheet metal bending with kink 22.Metalwork 2 adopts hardware in the present embodiment.Hardware has intensity and toughness preferably, helps to strengthen the intensity and the toughness of casing 1.
The bottom adhesive of glassy layer 31 touches eyeglass 3 and is positioned within the concave station 4 on parallel portion 21 and/or on the bottom surface 41 of concave station 4 time, and whole touch eyeglass fixed structure is compact.In the present embodiment bottom of glassy layer 31 be bonded on the parallel portion 21 by double faced adhesive tape 6 and/or the bottom surface 41 of concave station 4 on.
As further improvement of this embodiment, spacing preiection 5 is fixedly arranged on the bottom surface 41 of concave station 4 and the junction of the sidewall 42 of concave station 4 in the present embodiment.Spacing preiection 5 not only can play support glass layer 31 in this structure, thereby there are enough gaps between the inwall of assurance touch eyeglass 3 and casing 1, and can also play the bottom surface 41 of connection concave station 4 and the effect of the sidewall 42 of concave station 4, when guaranteeing on casing 1 injection moulding metalwork 2, casing 1 shrinkage degree basically identical everywhere, the gap between casing 1 inwall is more even.
As shown in Figure 4, spacing preiection 5 is bar shaped in the present embodiment, and its length direction along casing 1 extends.The length of spacing preiection 5 is long more, and then the power shared of every section spacing preiection 5 is then more little, help touching on the eyeglass 3 stressed everywhere evenly.
As shown in Figure 5 and Figure 6, the cross section of spacing preiection 5 is trapezoidal in the present embodiment, and the junction of the bottom surface 41 of its base and concave station 4 and the sidewall 42 of concave station 4 links to each other.To be connected area bigger with the sidewall 42 of the bottom surface 41 of concave station 4 and concave station 4 on the one hand for this structure spacing preiection 5, it is more firm to be connected with casing 1, and on the other hand, the top of spacing preiection 5 is the plane, rather than wedge angle, be difficult for because damage with glassy layer 31 collisions that touch eyeglass 3.
As illustrated in Figures 5 and 6, spacing preiection 5 parallels with the lower surface of glassy layer 31 near a side of the bottom of glassy layer 31 in the present embodiment.When the base abuts of glassy layer 31 was on spacing preiection 5 in this structure, the suffered impact force of the approaching side in spacing preiection 5 and the bottom of glassy layer 31 was more even, is difficult for damaging because of collision.
Portable terminal provided by the utility model comprises above-mentioned touch eyeglass fixed structure provided by the utility model and is fixed in the touch eyeglass 3 that touches on the eyeglass fixed structure as shown in Figure 6.
Because portable terminal provided by the utility model has and the identical technical characterictic of above-mentioned touch eyeglass fixed structure provided by the utility model, so both not only have unicity, and can produce identical technique effect, solves identical technical problem.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
