Description

keyboard elastic device

The utility model relates to a keyboard elastic device, which cannot be shifted or skewed during assembly, and is easy to locate and install.

The elastic devices used in the existing keyboards are divided into two types, the first is a traditional spring element, and the second is an elastic element of rubber material. Among them, the first type of spring element is usually used in the keyboard device of a desktop computer. Its disadvantage is that the spring element needs to have a certain length to maintain a certain elasticity. When the design of the keyboard becomes lighter and thinner, the traditional spring cannot meet the requirements. design needs. Thus, a second elastic element of rubber material is created. In the early stage, this elastic element was a single independent element. Although the thickness and weight of the keyboard were greatly reduced, it had to be assembled one by one according to the position of each key, which was inconvenient to assemble and would also cause displacement and skewing. Then a whole-piece elastic device is designed, which has a plurality of elastic bodies of the above-mentioned elastic elements, which can be assembled on the keyboard at one time. However, it is integrally formed. If one of the elastic bodies is damaged, the whole piece of elastic will be damaged. The components will all be scrapped, which will increase the burden of manufacturing costs, and the shape of the molding die will change, which will also cause the mechanical properties of each elastic body to be different, affecting the operation of the keyboard.

The purpose of the utility model is to provide a keyboard elastic device, which can be mounted on an electronic device in conjunction with keys and a circuit board.

The purpose of this utility model is achieved by providing a keyboard elastic device, which is mounted on an electronic device in cooperation with a key and a circuit board. The key has at least one base, and the elastic device includes: providing An elastic elastic body; a connecting portion extending outward from the elastic body and connected to the button; a knocking portion arranged perpendicularly from the elastic body toward the direction away from the connecting portion; outwardly from the elastic body The base is extended and fixed between the key base and the circuit board.

The advantage of the device of the utility model is that it can realize the demand of the keyboard design which is becoming lighter and thinner, which is convenient for installation, and at the same time, because the elastic body is extended outward with a base, when assembling, it can overcome the displacement caused by assembling a single component Or skewed, can also overcome the cost burden caused by assembling a whole-piece elastic device.

Below in conjunction with accompanying drawing, describe embodiment of the present utility model, wherein:

Fig. 1 is the three-dimensional exploded view of the keyboard device of the present invention;

Fig. 2 is a schematic cross-sectional view of the combination of the keyboard elastic device and the button device of the present invention;

Fig. 3 is a perspective view of the key cover, base and keyboard elastic device of the present invention.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the keyboard device 99 includes: a key device 10 , an elastic device 20 , a film circuit board 30 and a bottom plate 40 . The key device 10 mainly includes a key cover 12 , a cross link 14 and a base 16 . The key cover 12 is provided with a boss 122 for connecting with the elastic device 20; the base 16 is provided with a through hole 162 for the elastic device 20 to pass through and connect with the key cover 12, and the base 16 is in the through hole 162 A fastening portion 164 is provided around to fasten the elastic device 20 . The shape of the elastic device 20 is roughly an inverted bowl, which includes: an elastic body 22 , a connecting portion 24 , a knocking portion 26 and a base 28 . Wherein the elastic body 22 has a recessed space 221, along the vertical direction of the elastic body 22, a connecting portion 24 is extended outwardly, and a circular hole 242 is formed on it, which can be used to connect the boss 122 of the key cover 12; In the recessed space 221 of the elastic body 22, there is a knocking part 26 in the shape of a cylinder facing away from the connecting part 24, and there is a specific gap between the circuit 32 of the thin film circuit board 30 and the conductive bottom plate 40, Knock the film circuit board 30 with the cylinder of the knocking part 26, the circuit 32 of the film circuit board 30 can be contacted with the conductive bottom plate 40 to form a current path; Extended settings.

When assembling, put the elastic device 20 into the through hole 162 of the base 16 of the key device 10. Since the key base 16 has a fastening portion 164, its shape and size are designed according to the shape of the base 28 of the elastic device 20, so that the elastic device 20 can be positioned. In combination with the installation of the film circuit board 30 and the bottom plate 40 , the elastic device 20 can be completely fixed, so the elastic device 20 will not be displaced or skewed. Finally, the cross link 14 and the key cover 12 are assembled to the key base 16 in sequence.
