In the present embodiment, the supporting posts 203 are preferably integrally formed with the body 201. The end surface of the supporting column 203 far away from the key body 201 is provided with a groove 204, and the elastic element 202 is embedded in the groove 204. The elastic member 202 may be made of plastic, silicone, or other materials with elastic coefficient. In this embodiment, a silicone material is preferred, which may be TPU (Thermoplastic polyurethane elastomers). Because the silicone rubber has better elasticity, the elastic member 202 can be reset after being pressed. A function key, such as a snap dome, is disposed under the elastic member 202, and when the key body 201 is pressed, the function key can be touched to perform a corresponding input operation.

The dimension of notch 2041 of groove 204 is less than the dimension of trough bottom 2042 of groove 204. As shown in fig. 3 and 4, the longitudinal cross-sectional shape of the groove may be trapezoidal, inverted "T" or other shapes. Compared with the groove structure with the rectangular longitudinal section, the groove structure in the shape can enable the elastic piece embedded into the groove structure to have a larger contact surface with the groove, and the glue pulling capacity between the elastic piece and the groove is improved.

The elastic member 202 includes a contact portion 2021 and a connection portion 2022, and the connection relationship between the contact portion 2021 and the connection portion 2022 is preferably integrally formed. The contact portion 2021 has a hanging platform structure with at least one side protruding from the supporting pillar 203, as shown in fig. 5, the hanging platform structure on one side is a hanging platform structure 20241. It will be understood by those skilled in the art that the contact portion 2021 may also have a hanging platform structure protruding from the supporting column 203 at multiple sides, as shown in fig. 6, the three-side hanging platform structure is hanging platform structure 20242, hanging platform structure 20243, and hanging platform structure 20244. The platform structure and the contact portion 2021 may be integrally formed or riveted. In the embodiment of the present invention, in order to facilitate the assembly and further avoid the possibility that the key body falls off from the electronic device, it is preferable that the hanging platform structure and the contact portion 2021 are integrally formed. And the hanging table is made of rubber or silica gel. Of course, in practical application, the hanging platform can be made of other materials.

The body 201 includes at least three support posts 203. The elastic members 203 of the first supporting column 2031 and the second supporting column 2032 have at least one pair of hanging platform structures contacting the module holder 100; the first supporting column 2031 and the second supporting column 2032 are respectively located at two ends of the key body 201. As shown in fig. 8, the mount structure 20245 of the first support column 2031 and the mount structure 20246 of the second support column 2032 are arranged back to back in a direction parallel to the key body. It should be noted that the hanging table structure 20245 on the first supporting column 2031 and the hanging table structure 20246 on the second supporting column 2032 can also be arranged back to back in the direction perpendicular to the key body. It will be understood by those skilled in the art that when the elastic members 203 on the first supporting column 2031 and the second supporting column 2032 have more than one pair of hanging structures, the hanging structures and the module are matched with each other, so that the key module will not be separated from the module holder during use.

In some embodiments, as shown in fig. 7, the hanging table structure 2024 comprises a first surface 2061, a second surface 2062, and a third surface 2063, wherein the first surface 2061 is connected to the second surface 2062, the second surface 2062 is connected to the third surface 2063, and the first surface 2061 and the third surface 2063 are not in the same plane. The first surface is the lower surface that the platform structure hangs in the air, and the third surface is the surface that elastic component and notch contact, and the second surface is the surface of connecting first surface and second surface. The height difference between the first plane 2061 and the third plane 2063 can facilitate the demolding of the key structure. It will be understood by those skilled in the art that the first plane 2061 and the third plane 2063 may or may not be parallel to each other. When the first plane 2061 and the third plane 2063 are not parallel, the hanging platform structure and the module bracket should be ensured to be matched with each other, so that the key module cannot be separated from the module bracket when in use.
