The following describes a key according to an embodiment of the present application in detail with reference to fig. 1 to 4.

The key includes: a fixed plate 110, a rigid first connecting member 120, a rigid second connecting member 130, a first balance bar 140, and a second balance bar 150. The rigid first connecting member 120 is movably disposed at one side of the fixing plate 110; the rigid second connecting member 130 is movably disposed at one side of the fixing plate 110; the first balance bar 140 is movably connected with the first connecting member 120; the second balance bar 150 is movably connected with the second connecting member 130; noise caused by the connection of the first balance bar 140 and the fixed plate 110 can be eliminated by the movable connection of the first balance bar 140 and the first connecting member 120; the noise caused by the connection of the second balance bar 150 and the fixed plate 110 can be eliminated by movably connecting the second balance bar 150 and the second connecting member 130; therefore, the noise of the key is greatly reduced, and the user experience is improved.

In the embodiment of the present application, the fixing plate 110 serves to support the first link 120, the second link 130, the first balance bar 140, and the second balance bar 150.

If the first balance bar 140 and the second balance bar 150 are movably connected to the fixing plate 110, respectively, since the fixing plate 110 is a fixed structural member, the first balance bar 140 and the second balance bar 150 are likely to rub against the fixing plate 110 during the movement process to generate noise; since the first connecting member 120 is movably disposed at one side of the fixing plate 110, the first balance bar 140 is movably connected to the first connecting member 120, and the first connecting member 120 can move adaptively during the movement of the first balance bar 140, thereby reducing noise generated during the movement of the first balance bar 140; since the second connecting member 130 is movably disposed at one side of the fixing plate 110, and the second balance bar 150 is movably connected to the second connecting member 130, the second connecting member 130 can move adaptively during the movement of the second balance bar 150, so that noise generated during the movement of the second balance bar 150 can be reduced.

Here, the structure of the fixing plate 110 is not limited. For example, the fixing plate 110 may be a rectangular parallelepiped thin plate.

Here, the material of the fixing plate 110 is not limited. For example, the fixing plate 110 is made of metal so as to improve the supporting strength of the fixing plate 110.

In the embodiment of the present application, the structure of the first connecting member 120 is not limited. For example, the first connector 120 may have a plate-shaped structure.

Here, the material of the first connecting member 120 is not limited. For example, the material of the first connecting member 120 is plastic, so that the first connecting member 120 has certain rigidity and can reduce the weight of the first connecting member 120; in addition, the first connecting member 120 of plastic material can also reduce noise generated during the movement of the first balance bar 140.

Here, the implementation manner in which the first connector 120 is movably disposed at one side of the fixing plate 110 is not limited. For example, the first connecting member 120 and the fixing plate 110 are rotatably connected; also for example, the first connector 120 is rotatable and movable with respect to the fixing plate 110.

In the embodiment of the present application, the structure of the second link 130 is not limited. For example, the second connector 130 may have a plate-shaped structure.

Here, the material of the second link 130 is not limited. For example, the material of the second connecting member 130 is plastic, so as to make the second connecting member 130 have certain rigidity and reduce the weight of the second connecting member 130; in addition, the second link 130 made of plastic material can reduce noise generated during the movement of the second balance bar 150.

Here, the implementation manner in which the second connector 130 is movably disposed at one side of the fixing plate 110 is not limited. For example, the second link 130 is rotatably connected to the fixing plate 110; for another example, the second link 130 is rotatable and movable with respect to the fixed plate 110.

Here, the positional relationship between the second link 130 and the first link 120 is not limited. For example, as shown in fig. 1 and fig. 2, the first connecting member 120 is disposed opposite to the second connecting member 130, and the first connecting member 120 and the second connecting member 130 are disposed in a staggered manner in a first direction; wherein the first direction is the moving direction of the key; at this time, the second link 130 and the first link 120 form a butterfly structure.

As an example, as shown in fig. 1 and fig. 2, the first link 120 and the second link 130 may be rotatably connected, so that a linkage mechanism is formed between the first link 120 and the second link 130, and is used for preventing the key from deflecting to affect the use when the key cap 170 of the key is unevenly stressed; meanwhile, the first connecting piece 120 and the second connecting piece 130 are rotatably connected, so that the arrangement space of the first connecting piece 120 and the second connecting piece 130 can be reduced.

Here, the implementation manner of the rotatable connection between the first link 120 and the second link 130 is not limited. For example, the first connecting member 120 is provided with mounting holes at opposite sides thereof, and the second connecting member 130 is provided with mounting protrusions at opposite sides thereof, the mounting protrusions being inserted into the mounting holes; the first connecting member 120 and the second connecting member 130 are rotatably connected by inserting a mounting protrusion into a mounting hole.

Of course, the first connecting member 120 and the second connecting member 130 may not be connected to each other.

In the embodiment of the present application, the shape of the first balance bar 140 is not limited. For example, the first balance bar 140 has an n-type structure.

Here, the material of the first balance bar 140 is not limited. For example, the material of the first balance bar 140 is metal, so as to improve the supporting strength of the first balance bar 140.

Here, the implementation manner of the first balance bar 140 movably connected with the first link 120 is not limited. For example, the first balance bar 140 is rotatably connected with the first link 120; for another example, the first balance bar 140 can rotate and move with respect to the first link 120.

In the embodiment of the present application, the shape of the second balance bar 150 is not limited. For example, the second balance bar 150 has an n-type structure.

Here, the material of the second balance bar 150 is not limited. For example, the material of the second balance bar 150 is metal in order to improve the supporting strength of the second balance bar 150.

Here, the implementation manner of the movable connection of the second balance bar 150 and the second link 130 is not limited. For example, the second balance bar 150 is rotatably connected with the second link 130; for another example, the second balance bar 150 can rotate and move with respect to the second link 130.

Here, the positional relationship between the second balance bar 150 and the first balance bar 140 is not limited. For example, as shown in fig. 3, the second balance bar 150 is disposed opposite to the first balance bar 140, and the second balance bar 150 and the first balance bar 140 are disposed in a staggered manner in the first direction; wherein the first direction is the moving direction of the key.
