Problems solved by technology

Simply using adhesive to bond the waterproof breathable membrane and the shell, the adhesive's persistent viscosity and initial viscosity have performance defects, which cannot meet the needs of customers' products that work for a long time under deep water pressure and fail to meet the needs of safe waterproof protection
There is no perfect 1m to 70m deep water protection solution on the market, which directly limits the upgrade of smart hardware

Embodiment 1

[0044] Such as Figure 1-5 Air-permeable sound-permeable waterproof membrane, including housing 5 and pressing plate 7 installed in housing 5, waterproof and breathable diaphragm assembly; the top of said housing 5 is provided with a first through hole 8; said pressing plate 7 and housing 5 The position where the first through hole 8 is provided on the top constitutes a closed area, and the pressure plate 7 is in sealing connection with the housing 5; Corresponding, and the two are connected; a pressure support 11 is provided between the pressure plate 7 and the inner surface of the bottom of the housing 5; the pressure support 11 is a rib, a circuit board, a filler block or an electronic One of the components, the pressure support member 11 in this embodiment is a rib; and the pressure support member 11 can be fixedly connected with the housing 5 and the pressure plate 7 by means of gluing, welding, etc., or can be detachably connected by snap-fitting or the like. , as long ...

Embodiment 2

[0058] The air-permeable, sound-permeable and waterproof membrane described in this embodiment is basically the same as that in Embodiment 1, except that:

[0059] Such as Figure 6-8 As shown, the top of the housing 5 is flat; the longitudinal section of the pressure plate 7 is L-shaped at both sides of the second through hole 9, and the waterproof and breathable diaphragm assembly is installed in the pressure plate 7; The third adhesive layer 6 of the body 5.

[0060] The upper surface of the inner bottom of the pressing plate 7 is bonded to the lower surface of the waterproof and breathable membrane assembly through the fourth adhesive layer 12, that is, the support part 1 is bonded, and the fourth adhesive layer 12 is located between the first through hole 8 and the second The peripheral area of ​​the passage that through hole 9 forms; The depth of pressing plate 7 inside and the thickness summation of the 3rd bonding glue layer 6 equal the total thickness of waterproof b...

Abstract

The invention provides an air-permeable sound-permeable waterproof membrane. The air-permeable sound-permeable waterproof membrane comprises a shell and further comprises a pressure plate and a waterproof air-permeable membrane assembly mounted in the shell, wherein the shell is provided with a first through hole; the pressure plate and the part, where the first through hole is arranged, of the shell form a closed area; the pressure plate is hermetically connected with the shell; the pressure plate is provided with a second through hole; the second through hole is arranged at a position corresponding to the position of the first through hole, and the two through holes communicate with each other; the waterproof air-permeable membrane assembly is installed in the closed area, and is closely attached to and fixedly connected with both the shell and the pressure plate; the waterproof air-permeable membrane assembly comprises a waterproof air-permeable membrane; and the waterproof air-permeable membrane is the only member that blocks the communication between the first through hole and the second through hole. The air-permeable sound-permeable waterproof membrane of the invention hasgood water resistance and can resist water pressure of 1 to 70 meters; and when the air-permeable sound-permeable waterproof membrane cooperates with an intelligent hardware shell structure, a part using the membrane has water resistance, air permeability and sound permeability.

Description

technical field [0001] The invention belongs to the field of breathable and waterproof technology, and in particular relates to a breathable, sound-permeable and waterproof membrane suitable for application fields such as wearables, mobile communications, underwater instruments, sensors, and intelligent hardware. Background technique [0002] At present, the waterproof level of wearable / mobile communication / smart hardware generally does not exceed IPX6, IPX7 or the overall sealing welding of smart products is isolated from the external environment air and sound insulation. Simply using adhesive to bond the waterproof breathable membrane and the shell, the adhesive has performance defects in the stickiness and initial tackiness, which cannot meet the long-term work of the customer's product under deep water pressure, and cannot meet the needs of safe waterproof protection. There is no perfect solution for deep water protection from 1 meter to 70 meters on the market, which di...
