The present invention provides an embodiment of a key 400 mounting structure, which is shown in fig. 1-5, and includes a mounting substrate 100, and a key sliding hole 110 is formed on the mounting substrate 100. in some embodiments of the present application, the mounting substrate 100 is a mounting housing, and the mounting substrate 100 includes a cover body and a base, the cover body is fastened on the base and fixedly connected to the base, and a mounting space for mounting a power distributor element is defined between the cover body and the base.

When the key is installed, the key sliding hole 110 may be opened on the cover body, and opened along the length direction of the cover body.

The shape of the key sliding hole 110 may be a long hole, such as an oval or a rectangle.

An elastic sealing assembly 200 disposed at the bottom of the mounting base 100 and disposed around the key sliding hole 110, wherein the elastic sealing assembly 200 includes a smooth sliding fitting portion 210;

a fixing frame 300 located below the elastic sealing assembly 200 and fixed on the mounting base 100;

the key 400 comprises a main body part 410 which is slidably arranged on the installation base 100, the elastic sealing component 200 and the fixing frame 300 and is in clearance fit with the installation base 100, the elastic sealing component 200 and the fixing frame 300;

and a sliding part 420 which is located between the fixing frame 300 and the elastic sealing assembly 200 and compresses the elastic sealing assembly 200, and one side of the sliding part is in contact with the sliding fitting part 210, and the other side of the sliding part is in contact with the fixing frame 300.

The main body 410 corresponds to the main body of the key 400, and the sliding portion 420 is a sliding table formed to extend outward from the outer side of the main body 410, and the shape of the sliding table may be circular or square.

In some embodiments of the present application, the sliding table is disposed perpendicular to the body of the key.

The sliding table is correspondingly assembled at a position between the elastic sealing member 200 and the holder 300, and the main body portion 410 penetrates through the elastic sealing member 200, the holder 300 and the mounting base 100 to realize relative sliding with 3.

When the device is specifically arranged, a first sliding long hole is formed in the elastic sealing component 200, a second sliding long hole is formed in the fixing frame 300, and the upper half part of the main body part 410 penetrates through the first sliding long hole in the elastic sealing component 200 and then extends into the key sliding hole 110; the lower half portion of the main body 410 extends downward after passing through the second sliding long hole of the fixing frame 300.

Preferably, the outer diameter of the first sliding long hole is slightly larger than the outer diameter of the key sliding hole 110, and the main body 410 is in clearance fit with the first sliding long hole, the second sliding long hole and the key sliding hole 110, so that when the main body 410 of the key 400 slides in the main body, no friction is generated with the main body and the key sliding hole, and the sliding is smooth.

In the present embodiment, when the sliding part 420 of the key 400 is disposed between the elastic sealing assembly 200 and the fixing frame 300, and the fixing frame 300 is locked and fixed on the mounting base 100, so that when the fixing frame 300 is fixed in place, a pressing force is applied to the sliding part 420 on the key 400, and since the sliding part 420 is located below the elastic sealing assembly 200, the sliding part 420 transmits a pressing force to the elastic sealing assembly 200, so as to press and fix the elastic sealing assembly 200 on the periphery of the key sliding hole 110, thereby achieving the sealing of the periphery of the key sliding hole 110.

Even if water enters through the key sliding hole 110, the water is blocked outside due to the elastic sealing assembly 200 compressed between the mounting base 100 and the mounting base, so that the water is effectively prevented from entering the electronic product, and the waterproof effect is realized.

When the key 400 slides, the main body 410 slides relative to the key sliding hole 110, the elastic sealing assembly 200 and the bracket, and when the key slides, the main body drives the sliding portion 420 to slide synchronously, and during the sliding process, the sliding portion 420 is always pressed on the elastic sealing assembly 200, so that the elastic sealing assembly 200 is always in a compressed state. And the compressed elastic sealing assembly 200 is always arranged on the periphery of the hole of the sliding key 400 on the mounting base body 100, so that the periphery of the hole of the sliding key 400 can be completely and tightly attached by compressed foam, and the area possibly having waterproof failure is completely sealed, thereby achieving the purpose of sealing and waterproofing.

In order to prevent the sliding resistance of the key 400 from increasing after the elastic sealing assembly 200 is added, the sliding part 420 is in contact with the smooth sliding fit part 210 on the elastic sealing assembly 200, and during sliding, because the sliding fit part 210 is smooth, the resistance between the sliding fit part 210 and the sliding part 420 is small, and the key 400 can be ensured to slide smoothly.

The installation structure of the key 400 in this embodiment realizes the sealing of the circumference of the key sliding hole 110 through the arranged elastic sealing component 200, realizes the waterproof function, and reduces the friction between the key 400 and the elastic sealing component 200 through the relative sliding between the smooth sliding fit part 210 of the key 400 and the elastic sealing component 200, thereby ensuring the smooth sliding of the key 400.

In some embodiments of the present application, to further reduce the sliding friction between the key 400 and the fixing frame 300, the sliding portion 420 and the fixing frame 300 are in line contact when disposed.

In some embodiments of the present application, when the protrusion 500 is disposed on the fixing frame 300, or the protrusion 500 is disposed on the sliding part 420, the protrusion 500 may be a protrusion strip.

In some embodiments of the present application, in order to reduce the contact area between the sliding part 420 and the fixing frame 300 and reduce the friction between the key 400 and the fixing frame 300, the sliding part 420 and the fixing frame 300 may be point-contacted when disposed.

Specifically, a plurality of protruding posts may be disposed on the fixing frame 300 or the sliding portion 420.

The protruding cylindrical shape may be a circular protrusion, a cylindrical protrusion, etc., as long as point contact between the fixing frame 300 and the sliding part 420 can be achieved, and is not particularly limited herein.

In some embodiments of the present application, the spacing between the fixture 300 and the mounting base 100 is adjustable.

In particular, the fixing frame 300 may be locked and fixed to the mounting base 100 by a locking bolt or a locking screw.

The pressing force of the key 400 on the elastic sealing component 200 can be changed by adjusting the depth of the locking bolt or the locking screw screwed into the mounting base 100 to adjust the pressing force transmitted by the fixing frame 300 to the key 400.

Because the friction force between the elastic sealing assembly 200 and the sliding part 420 is in direct proportion to the pressing force of the sliding part 420 on the elastic sealing assembly 200, when in use, the gap between the fixing frame 300 and the installation base body 100 can be adjusted to change and provide the sealing waterproof pressing force, specifically, the screwing-in depth of the fixing frame 300 can be adjusted, the required pressing force can be quickly obtained according to the adjustment gap values corresponding to electronic products with different waterproof requirements, so that the elastic sealing assembly 200 can keep a proper pressing force to seal the key sliding hole 110, and can drive the key 400 to positively slide under a small acting force, and the universality is strong.

In some embodiments of the present application, the elastic sealing member 200 is an elastic foam member, which includes:

a base material having the sliding-fit portion 210 formed on the opposite side of the sliding portion 420, and the sliding-fit portion 210 may correspond to a smooth surface formed on the base material on the opposite side to the sliding portion 420.

A foam body 220 formed on the substrate, in some embodiments of the present disclosure, the foam body 220 may be foam molded directly on the substrate.

And the adhesive layer 230 is formed on the foam body 220, and the foam body 220 can be directly adhered and fixed on the mounting substrate 100 through the adhesive layer 230.

In some embodiments of the present application, the structure of the resilient seal assembly 200 may be configured to include: the elastic sealing strip and fix the base plate in elastic sealing strip bottom, the base plate bottom is smooth.

The sealing of the circumference of the key sliding hole 110 can be realized through the elastic sealing strip, and the friction force of the key 400 in the sliding process can be reduced by arranging the smooth base plate at the bottom of the elastic sealing strip, so that the smooth sliding of the key 400 is ensured.

In some embodiments of the present application, a plug portion 411 for plugging and unplugging a switch is formed on the main body portion 410, and the plug portion 411 is used for plugging a switch to be unplugged so as to drive the switch to be unplugged to move.
