Specific embodiment

Embodiment one

Referring to figs. 1 to each structural schematic diagram of the electronic equipment 100 of Waterproof push-button shown in Fig. 3.The electricity of Waterproof push-button Sub- equipment has the shell 100 of integral waterproofing, further includes the display 101 that can show information on shell 100.In display 101 lower section is provided with flexible keystroke 2, which interacts for user with electronic equipment.Installation is pressed on the housing The surface setting of the position shell 100 of key can accommodate the aperture 102 of key, the shape of aperture 102 and the pressing of flexible keystroke Portion 23 is identical.

Referring to Fig. 3, the flexible keystroke 2 includes pedestal 20 and the press section 23 being provided integrally on pedestal.It is described soft Property key press section 23 be arranged in the aperture 102, the top of press section 23 is exposed to outer user-friendly, and flexibility is pressed The pedestal 20 of key is housed in inside the shell 100；When user presses the press section 23, press section 23 can be with pressing It is up and down in the aperture 102.The area of aperture 102 described in the area ratio of the pedestal 20 of flexible keystroke 2 is big, prevents flexibility Key falls off.

The rubber or silica gel material that flexible keystroke 2 can be integrally formed, but can also with when it is known to those skilled in the art Other flexible materials be made.As long as the press section 23 and key pedestal 20 are structure as a whole, part is waterproof, ventilative.

Referring to Fig. 2, the position of press section 23 described in the bottom face of flexible keystroke, the cushion block 24 with outwardly convex is used for Directly contacted with stop bit part 103.The stop bit part 103 prevents the dockingundocking of press section 23 excessively pressing and shell 100.It is described to stop Position part 23 is the microswitch 103 connecting with electronic equipment internal electronic device, and microswitch 103 has one to prolong opening for Shen upwards Bar 104 is closed, the top of switch lever 104 is resisted with the cushion block 24.

Referring to Fig. 3, includes multiple independent press sections 23 on the pedestal 20 of flexible keystroke, have between each press section 23 The spacing of setting forms the first rib 21 to raise upward in the peripheral side of press section 23.Press section 23 with the first rib 21 Between have setting spacing formed a groove 210.The inside of the shell 10 has first be coupled with first rib 21 Seal groove 31, first seal groove 31 accommodate the peripheral side of the press section aperture 102 in the inner surface and being located at of shell.The One seal groove 31 to the first of downward Shen prolongs Shen wall 11 and extend downwardly second from prolonging between the setting of the interval of Shen wall 12 on shell 10 Away from surrounding.

It is installed rear first rib 21 to enter in the first seal groove 31, while described first prolongs Shen wall 11 into institute It states in the groove 210 on flexible keystroke, the top of the first rib 21 and the side connecting with first seal groove 31 pass through Sealant and the seal groove 31 bond.

In use if there is a small amount of water enters in flexible keystroke 2, the first rib 21 is higher than the table of the pedestal 210 Face is capable of forming the small container of a receiving water.When have a large amount of water enter the key 2 in due to the first rib 21 and first The therefore water sealed when between seal groove 31 cannot be introduced into the inside of shell.

In order to obtain good sealing performance under low temperature environment, the first rib 21 of flexible keystroke 2 and first sealing It is preferably interference fitted between slot 31, magnitude of interference can compensate for the shrinkage of the flexible keystroke 2 under cryogenic conditions.

The sealing means of above-mentioned first rib 21 and the first seal groove 31 can adapt to extreme temperature environment.Exist by actual measurement Minimum temperature be for -40 DEG C or maximum temperature be 85 DEG C, it is moist, key still is able to work normally under the conditions of water is splashed or soaked.

Embodiment two

Referring to Fig. 3 and Fig. 4, the second rib 22, the first rib is arranged in the peripheral side of the flexible keystroke 2 in the present embodiment 21 and second rib 22 composite structure and first prolong between Shen wall 11 and the composite structure of the second wall extension 12 formed labyrinth it is close Envelope.

More specifically, the peripheral side of press section forms the second rib 22 to raise upward, the first muscle on the pedestal 20 Item 21 forms the second seal groove 32 at a distance from the setting of the second rib 22 interval.

What is be the same as example 1 is the first seal groove 31 by prolonging Shen wall 11 and the second Yan Shenbi by first on shell 10 12 interval setting spacing surround, and the first rib 21 enters first seal groove 31 when flexible keystroke 2 assembles.Second Yan Shenbi 12 enter in the second seal groove 32.

The peripheral side that described second prolongs Shen wall 12 is provided with third and prolongs Shen wall 13, third prolongs Shen wall 13 from the upper of shell 10 Simultaneously prolong the spacing that Shen wall 12 keeps setting with second in the downward Shen in direction.Thus second prolongs Shen wall 12 and third prolongs Shen wall 13 and surrounds the Three seal grooves 33.

First rib 21 enter the first seal groove 31, second prolong Shen wall 12 enter the second seal groove 32 while, Second rib 22 enters in third seal groove 13 and using sealing glue bond.

Above-mentioned the first seal groove 31, the second seal groove 32, third seal groove 33 and the first rib 21, the second Yan Shenbi 12, third is prolonged between Shen wall 13 using sealing gluing knot.

The present embodiment the first seal groove 31, the second seal groove 32, third seal groove 33 and the first rib 21, the second Yan Shenbi 12, third prolong between Shen wall 13 formed labyrinth seal structure its with better seal effect.
