The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment provides an electronic terminal which comprises a key sealing structure. Referring to fig. 1 to 3, the key sealing structure includes a housing 1, a physical key 2, a gasket 3, and an elastic member 4. The outer side of the housing 1 is provided with a receiving groove 101. The physical key 2 is movably connected with the housing 1, and comprises a key main body 201 located in the accommodating groove 101, a connecting portion 202 fixedly connected to the key main body 201 and penetrating through the groove bottom of the accommodating groove 101 and extending to the inside of the housing 1, and a stressed portion 203 fixedly connected with the connecting portion 202 and located in the inside of the housing 1. The sealing gasket 3 is located outside the connecting portion 202 and between the key body 201 and the bottom of the accommodating groove 101. The elastic element 4 is located inside the housing 1 and connected to the stressed portion 203, and is configured to drive the key body 201 and the groove bottom of the accommodating groove 101 to approach each other to compress the sealing gasket 3.

It can be understood that, the physical key 2 is movably connected to the housing 1, and if water, dust, etc. enter the interior of the housing 1, the path thereof should be sequentially the gap between the key main body 201 and the groove wall of the accommodating groove 101, the gap between the key main body 201 and the groove bottom of the accommodating groove 101, the gap between the connecting portion 202 and the housing 1, and the interior of the housing 1.

The utility model provides a key sealing structure, when not carrying out the key operation, elastic component 4 makes key main part 201 and the tank bottom of storage tank 101 be close to each other in order to compress tightly sealed pad 3, therefore, the clearance between key main part 201 and the tank bottom of storage tank 101 is sealed up by sealed pad 3, and water and dust etc. can't enter the inside of casing 1; when the key is pressed, the pressing force moves the key main body 201 toward the inside of the housing 1, which is equivalent to making the key main body 201 and the bottom of the receiving groove 101 approach each other, so that the gasket 3 is pressed, the gap between the key main body 201 and the bottom of the receiving groove 101 is sealed by the gasket 3 again, and water, dust, etc. cannot enter the inside of the housing 1.

In this embodiment, an avoidance space is provided between the force receiving portion 203 and the inner wall of the housing 1; the elastic piece 4 extends into the avoiding space and is used for driving the force receiving part 203 to be away from the inner wall of the shell 1.

As an alternative embodiment, the elastic element 4 may be a compression spring located in the avoiding space, and when two ends of the compression spring respectively abut against the force-receiving portion 203 and the inner wall of the housing 1, the force-receiving portion 203 and the inner wall of the housing 1 have a tendency of moving away from each other, so as to force the key main body 201 and the groove bottom of the accommodating groove 101 to approach each other to compress the sealing gasket 3.

As another optional embodiment, the elastic member 4 includes a U-shaped elastic sheet 401 located in the escape space, and the U-shaped elastic sheet 401 includes a first vertical plate 4011 abutting against one side of the force receiving portion 203 close to the inner wall of the casing 1, a second vertical plate 4012 abutting against the inner wall of the casing 1, and an arc plate 4013 connecting the first vertical plate 4011 and the second vertical plate 4012.

It can be understood that, when the two sides of the U-shaped elastic piece 401 respectively abut against the inner side of the force-receiving portion 203 and the inner wall of the housing 1, the force-receiving portion 203 and the inner wall of the housing 1 tend to be away from each other, so as to force the key main body 201 and the bottom of the receiving groove 101 to approach each other to press the sealing gasket 3.

Referring to fig. 2, further, the number of the U-shaped elastic pieces 401 is two, and the second vertical plates 4012 of the two U-shaped elastic pieces 401 are fixedly connected by a connecting vertical plate 402 located on the side surface of the force receiving portion 203. Preferably, the connecting vertical plate 402 and the two U-shaped elastic pieces 401 are integrally formed, and may be formed by punching a steel plate or other materials.

Specifically, the two U-shaped spring pieces 401 are arranged opposite one another one above the other, so that a good pressing hand feeling can be ensured; further, the connecting riser 402 is located at the side of the force-bearing portion 203 to prevent the elastic member 4 from interfering with the physical key 2.

Alternatively, the gasket 3 is made of rubber. Further, the gasket 3 is made of soft rubber. It can be understood that the amount of deformation of the soft rubber is large, which is beneficial for the gasket 3 to be tightly attached to the bottom of the receiving groove 101, so as to prevent water, dust and the like from entering the interior of the housing 1.

In this embodiment, the sealing pad 3 is fixedly connected to the physical key 2 by in-mold injection molding. Further, one side of the sealing gasket 3 close to the key body 201 is attached to one side of the key body 201 close to the bottom of the accommodating groove 101.

When the sealing gasket 3 is attached and fixedly connected with the key main body 201, water cannot enter between the sealing gasket 3 and the key main body 201, so that the waterproof and dustproof performance of the key sealing structure can be further improved. It should be noted that, the mode of in-mold injection can not only realize the fixed connection between the sealing gasket 3 and the physical key 2, but also ensure that the sealing gasket 3 and the physical key 2 have good sealing performance.

It should be noted that the electronic terminal provided in this embodiment may be an MP3, a mobile phone, a tablet computer, or a line control earphone, etc.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
