It can be seen that the key assembly 100 further includes a conductive sheet 140.
[0038] In the embodiment, in combination with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 as shown, an embodiment of the present application proposes a key assembly 100, including:
[0039] A housing 110,
[0040] A keycap 120, the keycap 120 is movably connected to the housing 110;

[0043] In the technical solution of the embodiment of the present application, when the keycap 120 slides on the housing 110, since the conductive sheet 140 is disposed inside the keycap 120, the conductive sheet 140 will move along with the keycap 120. Therefore, the conductive sheet 140 can be in different positions along with the keycap 120; the keycap 120 has a first position and a second position; when the keycap 120 is in the first position, the conductive sheet 140 contacts the first conductive member 131, forming a first circuit, which can be used to control an electronic device to implement a function; when the keycap 120 is in the second position, the conductive sheet 140 contacts the first conductive member 131 and the second conductive member 132 simultaneously, forming a second circuit, which can be used to control an electronic device to implement another function; in the technical solution of the embodiment of the present application, by driving the conductive sheet 140 to move with the keycap 120, and then making it form different circuits with different conductive members, so as to control the electronic device to implement different functions, enabling the key assembly 100 to control the electronic device to implement multiple functions to match the increasingly powerful functions of the electronic device.
[0044] In the technical solution of the embodiment of the present application, the conductive sheet 140, the first conductive component 131, and the second conductive component 132 all adopt or include structures made of conductive metals / graphene, etc. In the embodiment, the conductive sheet 140, the first conductive component 131, and the second conductive component 132 all adopt or include structures made of copper (or copper alloy). For example, the conductive sheet 140 can be a copper sheet, a conductive graphene sheet, etc.; the first conductive component 131 and the second conductive component 132 are made of copper (or copper alloy).
[0045] Furthermore, in the embodiment, it is easy to understand that the keycap 120 is a non-conductive structure, such as a plastic part. In the embodiment, the keycap 120 includes a cap body and a bracket. The cap body and the bracket can be integrally formed or fixed by dispensing glue. The cap body facilitates the user to apply a pushing force to the keycap 120, and the bracket is built into the housing 110 and is used to fix the conductive sheet 140.
[0046] In the embodiment, a groove can be provided inside the keycap 120, and the conductive sheet 140 is adhesively attached in the groove; the conductive sheet 140 can also be fixed inside the keycap 120 by a connecting member.
[0047] As an alternative implementation of the above embodiment, the key assembly 100 further includes a third conductive component 133; wherein, the first conductive component 131 is located between the second conductive component 132 and the third conductive component 133 in the moving direction; the keycap 120 further has a third position; when the keycap 120 is in the third position, the conductive sheet 140 contacts the first conductive component 131 and the third conductive component 133. In this embodiment, the keycap 120 has a first position, a second position, and a third position; the conductive sheet 140 can have positions corresponding to the first position, the second position, and the third position respectively, and can respectively establish a circuit with the first conductive component 131, establish another circuit with the first conductive component 131 and the second conductive component 132, and establish yet another circuit with the third conductive component 133 and the first conductive component 131, so that the key assembly 100 can at least control the electronic device to implement three different functions.
[0048] In the embodiment, when the keycap 120 is in the first position, it can represent that the key assembly 100 is in the first gear; when the keycap 120 is in the second position, it can represent that the key assembly 100 is in the second gear; when the keycap 120 is in the third position, it can represent that the key assembly 100 is in the third gear. It is easy to understand that in some embodiments, the key assembly 100 can further include more conductive components, and the keycap 120 further has more positions, so that the conductive sheet 140 contacts different conductive components, thereby controlling the electronic device to implement more different functions.
[0049] As an alternative embodiment of the above embodiment, as Figure 4 and Figure 6 shown in the figure, the first conductive component 131 includes a first conductive head 1311; the conductive sheet 140 is provided with a first recess 141 and a second recess 142 adapted to the first conductive head 1311, and the first recess 141 and the second recess 142 are spaced apart in the moving direction. Wherein, when the keycap 120 is in the first position, the first conductive head 1311 cooperates with the first recess 141; when the keycap 120 is in the second position, the first conductive head 1311 cooperates with the second recess 142. In the technical solution of the embodiment of the present application, when the keycap 120 is in different positions, the first conductive head 1311 cooperates with the recesses at different positions on the conductive sheet 140, so that the conductive sheet 140 is in firm contact with the first conductive component 131.
[0050] In the embodiment, the conductive sheet 140 can be formed by stamping, as Figure 4 and Figure 6 shown, the conductive sheet 140 is formed with a wavy structure, and the area between adjacent wave crests is a recess; the first conductive head 1311 can be embedded in the recess, so that the conductive sheet 140 is in firm contact with the first conductive head 1311.
[0051] In the embodiment, the first conductive head 1311 can be set in a spherical shape, an ellipsoidal shape, a hemispherical shape, etc.; and the recess is an arc-shaped groove adapted to it.
[0052] In the embodiment, the conductive sheet 140 further includes a third recess (not labeled), the third recess is located on the side of the first recess 141 facing away from the second recess 142, and when the keycap 120 is in the third state, the first conductive head 1311 cooperates with the third recess.
[0053] As an alternative embodiment of the above embodiment, the first conductive component 131 further includes a first conductive elastic member 1312, and the first conductive elastic member 1312 is connected to the first conductive head 1311. In the embodiment, when the keycap 120 moves, the conductive sheet 140 moves accordingly, and the positions of the first recess 141 and the second recess 142 change accordingly; by connecting the first conductive head 1311 to the first conductive elastic member 1312, when the first conductive head 1311 enters the second recess 142 from the first recess 141 (or enters the first recess 141 from the second recess 142) during the movement of the conductive sheet 140, the area of the conductive sheet 140 located between the first recess 141 and the second recess 142 can apply pressure to the first conductive head 1311 to force the first conductive elastic member 1312 to deform, so that the first conductive head 1311 gives way, facilitating the smooth switching of the position of the conductive sheet 140 (key movement); at the same time, the first conductive head 1311 abuts firmly against the first recess 141 and the second recess 142 under the elastic force of the first conductive elastic member 1312.
[0054] As an alternative embodiment of the above embodiment, the first conductive component 131 further includes a first conductive sleeve 1313 and a first conductive elastic sheet 1314. The first conductive elastic member 1312 is disposed inside the first conductive sleeve 1313; the first conductive elastic sheet 1314 is connected to the first conductive sleeve 1313, and the first conductive elastic sheet 1314 is used to be disposed on the circuit board 200. In the embodiment, the first conductive sleeve 1313 provides a guiding function for the deformation of the first conductive elastic member 1312, preventing the first conductive elastic member 1312 from being skewed, and is electrically connected to the circuit board 200 through the first conductive sleeve 1313 and the first conductive elastic sheet 1314, facilitating the formation of a loop.

[0056] As an alternative implementation of the above embodiment, the second conductive component 132 includes a second conductive head 1321 and a second conductive elastic member 1322. The second conductive elastic member 1322 is connected to the second conductive head 1321. When the keycap 120 switches from the first position to the second position, the keycap 120 contacts the second conductive head 1321 and applies pressure to the second conductive head 1321 to force the second conductive elastic member 1322 to deform, thereby enabling the conductive sheet 140 to contact the second conductive head 1321. In the embodiment, when the keycap 120 moves, the conductive sheet 140 moves accordingly. The second conductive elastic member 1322 is connected to the second conductive head 1321, so that when the keycap 120 moves, the second conductive head 1321 forces the second conductive elastic member 1322 to deform, causing the second conductive head 1321 to retract, enabling the conductive sheet 140 to contact the second conductive head 1321, and the second conductive head 1321 contacts the conductive sheet 140 firmly under the elastic force of the second conductive elastic member 1322.
[0057] As an alternative implementation of the above embodiment, the keycap 120 is provided with an inclined surface 121. When the keycap 120 is in the first position, the inclined surface 121 contacts the second conductive head 1321. When the keycap 120 switches from the first position to the second position, the inclined surface 121 applies pressure to the second conductive head 1321 to force the second conductive elastic member 1322 to deform. When the keycap 120 switches from the first position to the second position, since the inclined surface 121 contacts the second conductive head 1321, when it moves, the inclined surface 121 applies pressure to the second conductive head 1321 to force the second conductive elastic member 1322 to deform, causing the second conductive head 1321 to retract, enabling the conductive sheet 140 to contact the second conductive head 1321.
[0058] As an alternative implementation of the above embodiment, the second conductive component 132 further includes a second conductive sleeve 1323 and a second conductive elastic sheet 1324. The second conductive elastic member 1322 is disposed within the second conductive sleeve 1323. The second conductive elastic sheet 1324 is connected to the second conductive sleeve 1323 and is adapted to be disposed on the circuit board 200. In the embodiment, the second conductive sleeve 1323 provides a guiding function for the deformation of the second conductive elastic member 1322, preventing the second conductive elastic member 1322 from being skewed, and is electrically connected to the circuit board 200 through the second conductive sleeve 1323 and the second conductive elastic sheet 1324, facilitating the formation of a circuit.
[0059] In an embodiment, the second conductive component 132 is a pogo pin component. In the embodiment, the second conductive head 1321 and the second conductive elastic member 1322 are riveted, and the second conductive elastic member 1322 and the second conductive sleeve 1323 are riveted.
[0060] In the above embodiment, the first conductive component 131, the second conductive component 132, and the third conductive component 133 may have the same structure and are insulated from each other, and are only configured to be electrically connected through the conductive sheet 140.
[0061] As an alternative embodiment of the above embodiment, in combination with Figure 1 , Figure 3 and Figure 5 shown, a sliding groove 111 is provided on the housing 110, the keycap 120 is disposed in the sliding groove 111, and the keycap 120 moves along the extending direction of the sliding groove 111; in the direction perpendicular to the extending direction, the sliding groove 111 restricts the movement of the keycap 120. In the embodiment, the keycap 120 is disposed in the sliding groove 111; the sliding groove 111 may be configured to extend along a direction parallel to the surface of the housing 110, for example, configured to extend along the length direction or the width direction of the housing 110. In the embodiment, the keycap 120 is configured to move along the length direction or the width direction of the housing 110, and is restricted from moving by the groove wall of the sliding groove 111 in the thickness direction of the housing 110.
