The present invention is further described in detail with reference to the drawings and the detailed description.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1-2, the present embodiment provides a combined type key structure of silica gel and plastic, which includes a plastic key support 1, a plastic key 2 disposed on the key support 1, a patch key 4 for supporting the plastic key 2, and a silica gel key 3 disposed between the plastic key 2 and the patch key 4.

Plastic button 2 pass through the screw with 1 fixed connection of plastic key-press support, silica gel button 3 are used for separating plastic button 2 and paster button 4, the back of silica gel button 3 is equipped with waterproof 3M glue film, and it is used for fixing silica gel button 3 on the paster button 4. The key column of the silica gel key 3 is of a pit type, and the key handle of the plastic key 2 is pressed at the pit position of the silica gel key 3. In this embodiment, based on the pit structure, the key handle of the plastic key 2 is correspondingly lengthened to extend to the pit area of the silicone key 3, so as to adapt to the fitting assembly with the silicone key 3, compared with the conventional connection form, in this embodiment, the distance between the key handle of the plastic key 2 and the electronic key handle on the PCBA is shortened, the thickness of the silicone is reduced, and the deformation of the silicone under pressure is shortened, as can be seen from fig. 3, the patch key 4 and the plastic key 2 are separated by the silicone key 3 with the thickness of 0.8mm, so that the waterproof purpose is achieved, the key hand feeling can be fully improved, and comfortable use experience is obtained.

The sectional area of the key column of the plastic key 2 is larger than that of the electronic key handle of the patch key 4. In this embodiment, based on the structure that the sectional area of the key post of the plastic key 2 is larger than the electronic key handle of the patch key 4, the plastic key handle and the electronic key handle are uniformly stressed, thereby improving the operation hand feeling.

The combined key structure of the embodiment has the following assembling process:

s1, fixing a plastic key 2 on a plastic key support 1 through a screw to obtain an assembly a;

s2, pressing the assembly a on the silica gel key 3 in a screw fastening mode to obtain an assembly b;

s3, the assembly b is arranged on the patch key 4;

in this embodiment, the combined key structure is obtained through S1 to S3.
