Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment, a kind of surface structure of cell phone intelligent protective case, as shown in figure 1, resilient membrane 1 is a rectangle set
Shape film, punching press can be integrally used, be molded, the mode such as hot melt produces, and this programme uses injection molding manner.Resilient membrane 1 can use
Leather, paper, synthetic paper, sheet, sheet metal, mylar sheet or other thin-film materials, this programme use flexible modeling
Waterproof material of the film as resilient membrane 1.
The thickness of resilient membrane 1 is excessively thin to influence button resilience dynamics, and the thickness of resilient membrane 1 is blocked up to be influenceed user and use hand
Sense, the film thickness of the resilient membrane 1 of this programme selection is 1.2mm, has both ensured that user in turn ensure that keyboard using feel
Resilience dynamics.
The upper right corner of resilient membrane 1 is recessed to form an oval embedded groove 2 downwards, can inlay mark in embedded groove 2.
Formed on resilient membrane 1 by the way of integral molded plastic and touch projection 3, touching the setting of projection 3 can touch user
Third dimension can be experienced during keyboard, preferably increases sense of touch when user touches.
As shown in Fig. 2 on four angles of the lower surface of resilient membrane 1, a locating convex block 4, locating convex block 4 are set respectively
It is embedded in an interference fit in the hole on lower floor's correspondence position, for fixing resilient membrane 1, locating convex block 4 uses soft
The materials such as rubber are glued in the specified location of resilient membrane 1 by high temperature.Such a chimeric mode on the one hand can be by resilient membrane 1
It is firmly fixed in lower floor's specified location, electronic equipment therein is played a good protection.On the other hand, installing
When can avoid being glued, with facilitate dismounting overhaul.Depression forms a rectangular key slot downwards on the back side of resilient membrane 1
5, such as switched for laying any button.Sealing flange 7 on the waterproof bound edge 6 of the surrounding of resilient membrane 1 can be fastened in down
The correspondence position of layer, play a part of further fixation and sealing function and play waterproof to greatest extent.
As shown in figure 3, resilient membrane 1 is between exocuticle 8 and functional layer 9, and plays a part of sealing and connect.
Exocuticle 8 uses waterproof material, plays preliminary waterproof action, and in order to preferably play sealing waterproof action, this programme is abandoned
Common planar sheet bonding mode, and cutting ferrule fixed form is used, such a mode can effectively play sealing waterproof action.
This programme is by the way of integral molded plastic, it is possible to achieve the waterproof being turned over downwards is formed at the edge of resilient membrane 1
Bound edge 6, waterproof bound edge 6 and resilient membrane 1 are vertical relation.The fold inward of waterproof bound edge 6, is formed in parallel with resilient membrane's 1
Flange 7 is sealed, sealing flange 7 can be fastened in the sealing neck 101 of the correspondence position of bottom plate 10.Because resilient membrane 1 has
Elasticity, so sealing flange 7 can be fastened in sealing neck 101, and the clamping under elastic returning effect, play further
Fixation, sealing function so that shipwreck from side and side wall of the lower section along functional layer 9 to permeate up, therefore with good anti-
Water-based energy.
Four circular positioning holes 91 are opened on four angles of functional layer 9 respectively, for positioning elastic top layer 1.
Installation steps：First functional layer 9 is arranged on the correspondence position of bottom plate 10, then resilient membrane 1 is enclosed on bottom plate 10
On, the locating piece on resilient membrane 1 is pressed on positioning hole 91 and positioned, and sealing flange 7 is stuck in sealing neck 101
It is interior, it is by the elastic returning effect of resilient membrane 1 that resilient membrane 1 and the cutting ferrule of bottom plate 10 is tight, form a key for having waterproof action
Body is checked and regulated, the functional layer 9 of centre can be effectively protected.The overall outside of keyboard finally is wrapped in exocuticle 8, forms production
Product.
As shown in figure 4, waterproof bound edge 6 is fixed with sealing strip 61 towards the one side hot melt of functional layer 9, sealing strip 61 is rubber
Bar, edge of the sealing strip 61 along functional layer 9 are surrounded by a ring, and sealing strip 61 is snapped onto in the groove of functional layer 9 so that anti-
Hydrophobic path increase between water bound edge 6 and the plate of functional layer 9.
