Specific embodiment

Embodiment one

Fig. 1 is please referred to water-proof electronic appliance 100 shown in Fig. 3, which sets the shell with integral sealing, in Portion is the chamber for accommodating electronic device and battery, be omitted for waterproof construction Fig. 1 to Fig. 3 inside clearer displaying in The electronic device and battery in portion.

The shell of water-proof electronic appliance 100 includes two main composition structures, respectively includes the first component 1 and second Both part 2 has a thin-wall construction wall first component and when second component is linked together by fastener first component Thin-wall construction 11 and second component thin-wall construction 21 be combined surround accommodate electronic device airtight chamber 18.

The top 16 of the thin-wall construction 11 of the first component is provided with the seal groove 17 for sealing referring to Fig. 2 and Fig. 3.It should Seal groove 17 prolongs Shen along the top 16 of the thin-wall construction 11 and forms a closed ring channel structures 17, in seal groove 17 It is internally provided with the gasket seal 14 with same closed ring structure, the width of gasket seal 14 is slightly smaller than the sealing The width of slot 17.The gasket seal 14 includes but is not limited to the material with good ductility such as rubber, silica gel, plastics.

The rib 25 for sealing is being provided at the top of second component thin-wall construction 21 24 with continued reference to Fig. 2.Rib 25 shape is identical as the shape of the seal groove 17 and gasket seal 14, when the first component 1 and second component 2 link together The rib 25 pushes down gasket seal 14, and the retentivity of fastener makes the rib 25 remain certain to gasket seal 14 Pressure to prevent water, gas, dust from immersing the airtight chamber 18 by gap between seal groove 17 and rib 25.

It should be noted that seal groove 17 and rib 25 are located at the first component when first component 1 and second component 2 are not connected with 1, seal groove 17 and rib when the peripheral side of the opening chamber 181,182 of second component 2, the first component 1 and second component 2 connect 25 peripheral sides for being located at the airtight chamber 18 surround the airtight chamber 18.

With continued reference to Fig. 2, the cooperation connecting with the fastener is respectively set on the first component 1 and second component 2 Structure 13,23；The seal groove 17 of the first component 1 and second component 2 and the peripheral side of rib 25 is arranged in these fit structures 13. And fit structure is not interfered with the airtight chamber 18, and fastener well known to those skilled in the art includes singly being not limited to: card The modes such as mouth, bolt and nut, riveting, welding.

By taking the tight M of screw is solid as an example, the fit structure is screw hole 13, and screw hole 13 is distributed in the four of the first component The position at a angle 12, while being arranged in 17 peripheral side of seal groove.Screw hole 23 is similarly provided on second component 2, The outside of the rib 25 is arranged in screw hole 23 on second component.Spiral shell both when the first component 1 and second component 2 connect Nail hole co-axially align.Screw hole 13 on the first component is through-hole, and the screw hole 23 on second component is blind hole, screw M Screw hole 13 on the first component 1 reaches in the screw hole 23 of second component 2.Position where screw hole, the first component 1 It thickens to form pier portion 12,22 to provide better bonding strength with the thin-walled of second component, screw hole is not connected to airtight chamber Guarantee the leakproofness of airtight chamber 18.

Referring to Fig. 3 in order to support to replace battery, the first component 1 includes the warehouse lid of battery compartment 19 and enclosed cell storehouse 19 31.The electronic device in 15 split cell of a partition and confined space 18 is arranged in the first component 1.The surface of the first component 1 includes The warehouse lid 31 of opening 191 for being connected to battery compartment is being open on 191 by screw cover.The peripheral side setting of the opening 191 is close Sealing groove 34, setting enters the rib 33 of the seal groove in the warehouse lid 31, and gasket seal 32, the electricity is arranged in the seal groove 34 Rib 33 when pond storehouse 19 is closed in warehouse lid 31 pushes down gasket seal 32.The sealing means of battery compartment 19 and the first component 1 in a word It is identical with the sealing means of second component 2.

There is the through-hole (not shown) passed through for the screw, battery compartment 19 seals channel opening on battery cabin cap 31 191 peripheral side is also equipped with screw hole, which is only to need to remove on screw when blind hole replaces battery to open warehouse lid i.e. It can；Warehouse lid 31 is loaded onto back after the completion of replacement and can be resealed.

Embodiment two

Referring to Fig. 4, the difference with embodiment one is seal groove and sealing rib is not simple one-to-one relationship, But form step-like seal groove and bead structures.Be arranged on the first thin-wall construction 40 of connection the first seal groove 41, Second seal groove 42 and the first rib 46.Third seal groove 45 and the second rib are set on the second thin-wall construction 48 of connection 47.Gasket seal 42,44,45 is respectively set in first, second, third seal groove.In the first thin-wall construction 48 and the second thin-walled When structure 40 is linked together by fastener, first rib 46 enters third seal groove 43, and the second rib 47 enters first Seal groove 41.And the first, second 46,47, muscle compresses the gasket seal 42,45 in the first third seal groove.Second is thin Part 49 on wall construction 48 between third seal groove 45 and the second rib 47 compresses the gasket in second seal groove 42 Piece 44.Above-mentioned three kinds of seal grooves cascade setting is capable of forming labyrinth seal structure, so that sealing effect greatly promotes.

In conclusion the utility model use seal groove, gasket and rib sealing means be capable of forming it is high-grade Sealing structure, can guarantee electronic equipment under the conditions of -40 DEG C to 80 DEG C of temperature just by this sealing structure of actual test Often.It supports battery cabin cap to open simultaneously, battery is replaced under the premise of sealing performance is unaffected, guarantee cruise duration.
