Description

A kind of three anti-mobile phone protecting cases

Technical field

The utility model belongs to the application of three anti-products, relates to the hermetically-sealed construction of digital electronic goods of mobile phone, mobile phone protecting case, panel computer, handheld terminal product, Intelligent bracelet and wrist-watch, health care electronic product, Smart Home electronic product.

Background technology

Realize mobile phone and there is good waterproof and dustproof function; need all gaps between mobile phone or mobile phone protecting case to seal reliably, these gaps comprise between handset front case and back cover, Mike region, headset area, charging jacks region, camera region, starting key region, volume button region.Mobile phone or the mobile phone protecting case at present with three anti-functions are all adopt to increase water proof ring; adopt screw or large area buckle simultaneously; face-piece and drain pan is made mutually to compress water proof ring to reach the object of waterproof; therefore this design cost is high, difficulty is large, hidden danger is many, efficiency is low, causes that product structure is complicated, bulky, profile is heavy.

Summary of the invention

The purpose of this utility model is open a kind of three anti-mobile phone protecting cases.

The utility model realizes like this, a kind of three anti-mobile phone protecting cases, comprise face-piece (1) and drain pan (2), described face-piece (1) is made up of face-piece frame (1-3) and face-piece facial mask (1-4), and the inner side of described face-piece frame (1-3) is provided with multiple ring-shaped groove; Described drain pan (2) is made up of drain pan frame (2-7) and drain pan facial mask (2-8), and the inner side of described drain pan frame (2-7) is provided with many annular protrusions; Many annular protrusions of described drain pan frame (2-7) engage with multiple ring-shaped grooves of described face-piece frame (1-3) are staggered, and many annular protrusions of drain pan frame (2-7) are intercalated in multiple ring-shaped grooves of described face-piece frame (1-3).

In a kind of three anti-mobile phone protecting cases, on face-piece frame (1-3) inner side, the width of ring-shaped groove is between 0.5 millimeter to 2 millimeters.

In a kind of three anti-mobile phone protecting cases, the width of the upper interior annular projection of drain pan frame (2-7) is between 0.6 millimeter to 2.1 millimeters.

In a kind of three anti-mobile phone protecting cases, the width maximum of ring-shaped groove on face-piece frame (1-3) inner side that the width maximum of the upper interior annular projection of drain pan frame (2-7) is greater than relevant position.

Implement the technical program, have following beneficial effect: without any need for waterproof apron, waterproof and dustproof is reliable and stable, and degree of protection can reach IP67, and simultaneously production cost is low, efficiency is high, directly mobile phone product design can be obtained ultra-thin, fashion, light and handy.

embodiment:

Below in conjunction with drawings and Examples, the utility model is described in further detail.

A kind of three anti-mobile phone protecting cases, comprise face-piece (1) and drain pan (2), by in-mould injection technique, the face-piece frame (1-3) of face-piece (1) adopts TPPE material, and the face-piece facial mask (1-4) of face-piece (1) adopts transparent PC material; The drain pan frame (2-7) of drain pan (2) adopts TPU material, and the drain pan facial mask (2-8) of drain pan (2) adopts transparent PC material.

After face-piece (1) injection molded, fingerprint film (1-1) is bonded at the position, hole that face-piece (1) below is corresponding; Be bonded at by receiver waterproof membrane (1-2) on the upper corresponding square hole of face-piece (1), the assembling of face-piece (1) just completes.

After drain pan (2) injection molded, back side miaow head waterproof membrane (2-1) is bonded on position, hole corresponding to drain pan (2) back side, bottom surface miaow head waterproof membrane (2-2) is bonded on the position, hole below drain pan (2), camera eyeglass gum (2-6) is attached on camera eyeglass (2-4), and then on the shooting head bore position adhering on drain pan (2), 3 drain pans location stopple gum (2-5) are attached on 3 drain pans location stopple (2-3), and then on 3 location holes adhering on drain pan (2), the assembling of drain pan (2) just completes.

As shown in Figure 9, this embodiment face-piece frame (1-3) inner side be provided with 2 ring-shaped grooves between A, C, E; 2 annular protrusions B, D are provided with in drain pan frame (2-7) inner side; A, B, C, D, E adopt the design of back-off shape, and B is intercalated into the groove between A, C, and C is intercalated into the groove between B, D, and D is intercalated into the groove between C, E.

As shown in Figure 9:

Groove width between A, C is a, and the present embodiment is got a and is of a size of 1.0 millimeters.

The root thickness of C is b, and the present embodiment is got b and is of a size of 0.8 millimeter; The head thickness of C is c, and because C is back-off shape, therefore the size of c is greater than the size of b, and the present embodiment is got c and is of a size of 1.2 millimeters.

Groove width between C, E is d, and the present embodiment is got d and is of a size of 1.0 millimeters.

The head thickness of B is e, and the present embodiment is got e and is of a size of 1.5 millimeters.

Minimum spacing between B, D is f, and the present embodiment is got f and is of a size of 0.6 millimeter.

The head thickness of D is g, and the present embodiment is got g and is of a size of 1.5 millimeters.

When C is intercalated into the groove between B, D, due to the root thickness b=0.8 millimeter of C, be greater than minimum spacing f=0.6 millimeter between B, D, because C is back-off structure, therefore B, D can clamp the two sides of C thus realize the interference seal of two sides; Owing to being interference fit between C and B, D, may there is the risk of not exclusively sealing in the impact of its reaction force, because this increasing structure A, E; A, E can extrude B, D, and then B, D extrude C again, thus can prevent outer distortion.

In addition, the head thickness g=1.5 millimeter of D, the groove width d=1.0 millimeter between C, E, g>d, can realize the interference seal of groove between D and C, E; The head thickness e=1.5 millimeter of B, the groove width a=1.0 millimeter between A, C, e>a, can realize the interference seal of groove between B and A, C.

In sum, from outside to inside, first sealing is D and C, the interference fit seal that formed between E; The interference fit seal that second sealing is C and B, formed between D; The interference fit seal that three seals is B and A, formed between C; By this three seals, finally reach cocksure sealed waterproof effect.
