The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

Please refer to FIG. 1 , which is a combined sectional view of a combination of keyboard keys of the present invention. The present invention is a combination of keyboard keys 1 including a bottom plate 10, a membrane switch 20, a keycap 30 and an elastomeric structure 40. The membrane switch 20 is disposed on the bottom plate 10, and the elastic structure 40 is sandwiched between the keycap 30 and the bottom plate 10 for triggering the membrane switch 20 and the elastic lifting keycap 30 so that the keycap 30 passes through the The arrangement of the elastomeric structure 40 is movable up and down relative to the base plate 10. The elastomer structure 40 is described in more detail later.

In an embodiment of the present invention, the keycap 30 is substantially a rectangular cap, but is not limited thereto. Moreover, the membrane switch 20 is disposed corresponding to the position of the keycap 30. In actual implementation, the membrane switch 20 can be located on a thin film circuit board. It should be noted that the configuration of the membrane switch 20 can be adjusted according to actual needs. In actual use, the membrane switch 20 can also be set. Below the bottom plate 10, the bottom plate 10 is provided with an opening at a corresponding portion of the membrane switch 20 to expose the membrane switch 20.

As shown in Fig. 2, it is a cross-sectional view showing the elastomer structure of the present invention. In this embodiment, the elastomer structure 40 is substantially in the shape of a bowl, and includes an abutting platform 41, an elastic supporting body 42 and a contact block 43. The elastic support body 42 is located at a side edge of the abutment platform 41 and extends away from the abutment platform 41. Further, the contact pressure block 43 is connected to the bottom of the abutment platform 41, and the contact block 43 and the A pressing space 400 is formed between the elastic supporting bodies 42 , and the pressing block 43 has a first recessed portion 430 on a side away from the abutting platform 41 for deformation when pressed to increase the pressing stroke.

Specifically, the elastic support body 42 includes a flexible surrounding wall 421 and a supporting ring block 422, wherein one side of the flexible surrounding wall 421 is connected to the abutting platform 41, and the other side of the flexible surrounding wall 421 The support ring block 422 is connected.

Preferably, the outer peripheral edge of the support ring block 422 protrudes from the outer peripheral surface of the flexible surrounding wall 421, whereby the support ring block 422 can provide a better supporting force to the elastic support body 42. In this embodiment, the first recessed portion 430 of the contact block 43 has a semi-elliptical shape, but may be rectangular or irregular, and its shape is not limited thereto. Preferably, the first recessed portion 430 is located in the middle of the bottom surface of the contact block 43 , and a pressing portion 431 is formed on the periphery of the first recessed portion 430 .

In addition, in the embodiment, the abutting platform 41 further includes a second recessed portion 432 on a side away from the contact block 43 for deformation during pressing to increase the pressing stroke. The second recessed portion 432 is disposed at the center of the contact block 43, and its appearance can be changed according to actual needs.

Please refer to FIG. 3 again, which is a schematic diagram of the combination of the keyboard keys of the present invention and the structure of the elastic body. As shown in the figure, after the combination of the keyboard keys 1 of the present invention is completed, the abutment platform 41 of the elastic structure 40 abuts against the keycap 30; and the touch block 43 is corresponding to the film. Above the switch 20, specifically, the pressing portion 431 of the contact block 43 is disposed corresponding to the position of the membrane switch 20.

Please refer to FIG. 4 and FIG. 5 separately, which are respectively a schematic diagram of the flexible deformation of the elastic structure of the present invention and the actuation of the membrane switch. As shown in FIG. 4, when an external force acts on the keycap 30, the flexible surrounding wall 421 of the elastic supporting body 42 is first flexibly deformed, and the abutting platform 41 and the contact block 43 are moved toward the bottom plate 10. The second depressed portion 432 of the abutting platform 41 is concavely deformed, and the first depressed portion 430 is deformed to further increase the depression displacement of the key cap 30 to enhance the elastic body. The displacement stroke of the whole structure 40 is finally pressed against the membrane switch 20, so that the membrane switch 20 is triggered to output an electronic signal to issue a control command corresponding to the button.

In detail, before pressing, the vertical distance d between the lower edge surface of the contact structure 43 of the elastic structure 40 and the lower edge surface of the elastic support body 42 is a predetermined pressing stroke of the original elastic body structure 40 (refer to FIG. 1). The first recessed portion 430 is disposed in the middle of the bottom surface of the contact block 43 of the elastic structure 40, and the second recessed portion 432 is disposed on the abutting platform 41, so that the vertical distance of the upper edge surface of the abutting platform 41 after pressing is greater than the pressing The vertical distance d between the lower edge surface of the front contact block 43 and the lower edge surface of the elastic support body 42. Thereby, the displacement stroke of the elastic body structure 40 can be increased at the time of pressing under the height limitation of the thinned keyboard, so that the combination 1 of the keyboard keys has a good hand feeling.

Please refer to FIG. 6 again, which is another embodiment of the elastomer structure of the present invention. This embodiment is substantially the same as the previous embodiment, and the elastomer structure 40a is substantially in the shape of a bowl, including An abutting platform 41a, an elastic supporting body 42a and a contact block 43a, and the contact block 43a has a first recessed portion 430a on a side away from the abutting platform 41a. The difference between the embodiment is that the abutting platform 41a is a plane away from the side of the contact block 43a (the first recessed portion 430a), and the other manners are not different, and details are not described herein. Therefore, when an external force acts on the elastic body structure 40a, the displacement of the first recessed portion 430a can be transmitted to increase the displacement stroke of the entire elastic body structure 40a.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the patents of the present invention. Other equivalent variations of the patent spirit using the present invention are all within the scope of the patent.
