Detailed ways

The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings.

Referring to FIG. 3 , FIG. 4 , and FIG. 5 , the waterproof button 2 of a preferred embodiment of the present invention includes a button body 21 , a waterproof ring 22 and a hard support 23 combined with the button body 21 . The button body 21 is made of elastic material such as rubber or silicone, and includes a cap 211, at least one pressing portion 212 and a first plate 213. The cap 211 includes a top wall 214 and a top wall 214 The ring-shaped surrounding wall 215 extends downward, and the first disk portion 213 extends laterally from the bottom edge of the surrounding wall 215. In this embodiment, the outline of the first disk portion 213 is roughly rectangular, and its bottom surface is long along both sides. A flange 216 protrudes from the outer edges of each side. Of course, the shape and number of the flanges 216 are not limited to this embodiment, and may vary depending on the shape of the key body 21 . The pressing portion 212 extends downward from the bottom of the top wall 214 and is surrounded by the surrounding wall 215 . The waterproof ring 22 protrudes from the outer surface of the surrounding wall 215 and is distributed in a ring shape. In this embodiment, the waterproof ring 22 is integrally connected with the key body 21 .

The rigid supporting member 23 includes a supporting portion 231 and a second plate portion 232 extending outward from the bottom edge of the supporting portion 231 . The supporting portion 231 is disposed around the surrounding wall 215 . In this embodiment, the hard support 23 is formed by punching stainless steel sheets, but its material can also be other metal materials or hard non-metallic materials. The support part 231 is in the shape of a ring sheet. In the key body 21, the support part 231 is located on the inner wall surface of the surrounding wall 215, and the second plate part 232 is combined with the bottom surface of the first plate part 213 of the key body 21, and it is worth noting that when the hard support part 23 is combined In the case of the key body 21, the waterproof ring 22 is distributed around the height range a of the wall 215 and at least partly overlaps with the support portion 231. In this embodiment, the waterproof ring 22 is distributed over at least half of the height range a around the wall 215 and the support portion 231 overlaps, in other words, the support portion 231 is disposed so that the surrounding wall 215 overlaps at least half of the height range a of the waterproof ring 22 , and even in a partial position, the support portion 231 almost completely overlaps the waterproof ring 22 .

In this embodiment, the way of combining the hard support 23 with the key body 21 may be to form the key body 21 and the hard support 23 separately, and then combine the hard support 23 with the key body by hot pressing. 21, or form the hard support 23 first, and then form the key body 21 on the hard support 23 by in-mold molding.

The waterproof button 2 can be arranged on an electronic device casing 3, for example, the electronic device casing 3 includes a casing wall 31 and an opening 32 arranged in the casing wall 31, and the casing wall 31 has an inner surface 311 and an exposed outer surface 312 , when the waterproof button 2 is arranged on the electronic device casing 3, the first plate portion 213 of the button body 21 is attached to the inner surface 311 of the casing wall 31, the cap portion 211 is extended into the opening 32 and its top wall 214 passes through the opening 32 The outer surface 312 of the casing wall 31 is exposed for pressing, and the waterproof ring 22 abuts against the edge of the inner hole of the opening 32 .

When the top wall 214 of the cap portion 211 is pressed, the portion of the top wall 214 that is not provided with the pressing portion 212 will be deformed, so that the pressing portion 212 will be displaced inward to touch and press the circuit unit 33 in the housing 3 of the electronic device. . The circuit unit 33 referred to here is a touch switch disposed on the circuit board 331 .

It is worth noting that since the key body 21 is made of elastic material, the rigidity of the surrounding wall 215 is enhanced by the setting of the support part 231, and since the support part 231 at least partially overlaps with the waterproof ring 22, therefore, When the waterproof ring 22 abuts against the inner hole edge of the opening 32, the surrounding wall 215 is not easy to deform in the direction of the contacting part 212 because the waterproof ring 22 abuts against the inner hole edge of the opening 32, thereby affecting The degree to which the waterproof ring 22 abuts against the inner edge of the opening 32, in other words, the support portion 231 can support the waterproof ring 22, so that the waterproof ring 22 is more closely abutted against the inner edge of the opening 32, maintaining its waterproof effect , and the more the support part 231 overlaps with the height range a of the waterproof ring 22, the better the effect of supporting the waterproof ring 22 will be. In addition, by making the waterproof ring 22 tightly abut against the inner hole edge of the opening 32 , the frictional force can also prevent the waterproof button 2 from being easily displaced relative to the opening 32 and detached from the electronic device housing 3 .

Another effect of the support part 231 is that when the cap part 211 is pressed, due to the support part 231, the cap part 211 will not collapse and deform as a whole, and the fingers can still vaguely feel the top edge contour of the support part 231 when pressing And more pressing touch.

In addition, in this embodiment, since the second plate portion 232 of the hard support member 23 is combined with the first plate portion 213 of the key body 21, when the key body 21 is arranged on the electronic device casing 3, the second plate portion 232 The rigidity of the first plate portion 213 can also be increased to support against the inner surface 311 of the housing wall 31 , so as to prevent the key body 21 from being easily pulled out toward the outer surface 312 of the housing wall 31 .

It should be further explained that since the button body 21 is arranged in the opening 32 of the shell wall 31, it corresponds to the circuit unit 33 in the electronic device casing 3. By forming the two flanges 216, the button body 21 and the circuit board can be reduced. The distance between 331 can also avoid that when the entire waterproof key 2 is pressed, the key body 21 is easily displaced into the electronic device housing 3 due to the distance from the circuit board 331 being too far away.

In other implementations, if the strength of the first plate portion 213 of the key body 31 is sufficient, the rigid support member 23 can also omit the second plate portion 232 .

After testing, the waterproof button 2 of this embodiment provided on the housing 3 of the electronic device can reach the waterproof level of IPX7.

In summary, the utility model utilizes the setting of the hard support 23 to enhance the waterproof effect of the waterproof button 2. Since the structure of the hard support 23 is relatively simple, the manufacturing cost is low, and the hard support 23 is directly combined In the key body 21, the required assembly time and the required space can also be greatly reduced, so no matter compared with the known ones in Fig. 1 or Fig. 2, the waterproof key 2 of the present utility model does have functional advantages. enhance.

But what is described above is only the preferred embodiment of the present utility model, when can not limit the scope of the present utility model implementation with this, promptly all the simple equivalent changes that are made according to the scope of claims of the present utility model and the content disclosed in the specification sheet Modifications still belong to the scope covered by the utility model patent.
