[0002] A key is a common input device and is widely used in various fields. A key generally includes a keycap and a switch. The keycap is slidably installed in a keyhole of a housing. When a user presses the keycap, the keycap slides along the keyhole and presses the switch to trigger the switch. After the switch is triggered, when the user releases the keycap, the keycap needs to return to its initial position before being pressed. The keycap can be pushed back to the initial position by the rebound of the switch, or an elastic arm can be provided at the keyhole to push the keycap back to the initial position.

[0003] When the keycap rebounds through the switch, the pressing force of the keycap is small, resulting in a poor pressing feel of the keycap; when the keycap rebounds through the elastic arm, when installing the keycap, the keycap needs to bypass the elastic arm, making the installation of the keycap very inconvenient and reducing the assembly efficiency of the key.

[0041] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0042] In the first aspect, as Figures 1 to 3As shown in the figure, an embodiment of the present application provides a key structure 100, which includes a housing 1, a bottom plate 2, and a keycap 3. The housing 1 has opposite inner and outer sides, and the bottom plate 2 is disposed inside the housing 1 to protect the bottom plate 2. The housing 1 is provided with a first hole 11 that penetrates the housing 1 along a first direction X. A switch 21 is disposed on a side of the bottom plate 2 facing the housing 1, and the position of the switch 21 corresponds to the position of the first hole 11. The keycap 3 is disposed between the housing 1 and the bottom plate 2 and partially disposed in the first hole 11, so that the keycap 3 can be pressed through the first hole 11 to trigger the switch 21. Among them, the position of the switch 21 corresponds to the position of the first hole 11, that is, when viewed along the first direction X, the projection of the switch 21 is located within the projection of the first hole 11, or the projection of the switch 21 partially coincides with the projection of the first hole 11, so that the switch 21 can be pressed through the first hole 11.

[0043] For the above-mentioned housing 1, as Figures 1 to 3 shown, the housing 1 can be rectangular. The thickness direction of the housing 1 can be perpendicular to the first direction X, that is, the first hole 11 penetrates the housing 1 along the thickness direction of the housing 1. Optionally, the first hole 11 is a round hole, a square hole, or an oval hole.

[0044] In some embodiments, as Figure 2 shown, the cross-section of the first hole 11 is a shape approximately rectangular surrounded by a curve.

[0045] The housing 1 and the bottom plate 2 can be connected. Exemplarily, as Figures 2 to 4 shown, a second hole 12 is disposed on a side of the housing 1 facing the bottom plate 2, and a third hole 22 is disposed on the bottom plate 2. The key structure 100 further includes a fastener 4, and the fastener 4 passes through the second hole 12 and the third hole 22 to connect with the bottom plate 2. Optionally, the second hole 12 is a threaded hole, the third hole 22 is a through hole, and the fastener 4 is a screw.

[0046] In some embodiments, as Figure 3 shown, a connecting column 13 is disposed on a side of the housing 1 facing the bottom plate 2, and the second hole 12 is opened at the end of the connecting column 13, that is, the end of the connecting column 13 is connected to the bottom plate 2 through the fastener 4, so that there is a gap between the housing 1 and the bottom plate 2 to accommodate the switch 21 and a part of the keycap 3.

[0047] For the above-mentioned bottom plate 2, as Figures 1 to 3 shown, the bottom plate 2 can be rectangular. The thickness direction of the bottom plate 2 can be perpendicular to the first direction X, that is, the bottom plate 2 is parallel to the housing 1. Optionally, the bottom plate 2 is a PCB board, and the switch 21 can be soldered to the bottom plate 2. Optionally, the switch 21 is a tactile switch 21, and the operating force thereof, that is, the force range for pressing the tactile switch 21 to trigger it, can be selected in the range of 1N to 3N.

[0048] For the above-mentioned keycap 3, asFigures 2 to 4 As shown, the keycap 3 includes a supporting portion 31, an elastic portion 32 and a pressing portion 33. The supporting portion 31 is arranged between the base plate 2 and the housing 1. The elastic portion 32 connects the supporting portion 31 with the pressing portion 33. The pressing portion 33 is at least partially arranged in the first hole 11. When the pressing portion 33 is pressed, the elastic portion 32 is deformed, and the elastic portion 32 applies a force opposite to the pressing direction to the pressing portion 33, thereby increasing the elastic force of the keycap 3 pressing. Here, the elastic force of the keycap 3 pressing refers to the reaction force applied to the user in the process of pressing the keycap 3 so that the keycap 3 triggers the switch 21. The reaction force is applied to the user when the keycap 3 is pressed and released. By continuously pressing the pressing portion 33, the pressing portion 33 can contact and squeeze the switch 21 to trigger the switch 21, that is, the pressing portion 33 is used to trigger the switch 21. Optionally, the elastic portion 32 is made of silicone or rubber.

[0049] The elastic force of the switch 21 is usually small, so that a small force can trigger the switch 21 when pressing the keycap 3, which is easy to be accidentally touched, and the elastic force when releasing the keycap 3 is also small, so the pressing feel of the keycap 3 is poor. In the embodiment of the present application, an additional reaction force is applied to the user through the keycap 3, so that a larger force is required to trigger the switch 21 when pressing the keycap 3, which is not easy to be accidentally touched, and there is also a larger elastic force when releasing the keycap 3, which is conducive to improving the pressing feel of the keycap 3. It can be understood that the elastic force of the keycap 3 should not be too large. When the elastic force of the keycap 3 is too large, it will make the case difficult to press. The elastic force of the switch 21 is usually small, so increasing the elastic force of the keycap 3 can improve the pressing feel of the keycap 3.

[0050] In the embodiment of the present application, the keycap 3 realizes rebound through its own elastic part 32, so there is no need to set up an additional elastic arm. The elastic arm is usually set on the housing 1, and the elastic arm will abut against the side of the keycap 3 away from the housing 1. When installing the keycap 3, the elastic arm will hinder the installation of the keycap 3. It is necessary to bend the elastic arm before installing the keycap 3 so that the keycap 3 bypasses the elastic arm, which makes the installation of the keycap 3 very inconvenient and reduces the assembly efficiency of the key structure 100. However, the present application does not need to set up an elastic arm, which can simplify the installation steps of the keycap 3 and improve the assembly efficiency of the key structure 100.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, when viewed along the first direction X, the shape and size of the pressing portion 33 match the shape and size of the first hole 11. That is, along the first direction X, the shape and size of the cross section of the pressing portion 33 are the same as the shape and size of the cross section of the first hole 11, and the pressing portion 33 can slide in the first hole 11 along the first direction X; the inner wall of the first hole 11 prevents the pressing portion 33 from moving relative to the housing 1 in a direction perpendicular to the first direction X, thereby reducing the shaking of the pressing portion 33 and improving the feel of the keycap 3 when pressed.

[0052] In some embodiments, Figure 4 and Figure 5 As shown, a contact surface 331 is provided on the side of the pressing portion 33 facing away from the base plate 2, and a chamfer 332 is provided on the edge of the contact surface 331. The contact surface 331 is the surface that contacts the pressing portion 33 when the user presses the pressing portion 33. It should be noted that the chamfer 332 on the edge of the contact surface 331 is the chamfer 332 at the connection between the contact surface 331 on the pressing portion 33 and other surfaces of the pressing portion 33. The connection between the contact surface 331 and other surfaces of the pressing portion 33 is usually a non-smooth connection, for example, having an obtuse angle, so it will compress the fingers and cause pain. By providing a chamfer 332 on the edge of the contact surface 331, the problem that the edge of the contact surface 331 is sharp and causes pain in the user's fingers when pressing the keycap 3 can be improved, thereby improving the comfort of the user in pressing the keycap 3.

[0053] For the chamfer 332, if Figure 4 and Figure 5 As shown, in some embodiments, the chamfer 332 is a curved chamfer 332. The chamfer 332 is usually planar, and on an axial workpiece, the chamfer 332 is usually conical, and the connection between the chamfer 332 and other surfaces of the pressing portion 33 usually still has an obtuse angle. The curved chamfer 332 means that the chamfer 332 is curved, and compared with the parallel chamfer 332, the curved chamfer 332 can increase the obtuse angle of the connection between the curved chamfer 332 and other surfaces of the pressing portion 33, thereby further improving the comfort of the user pressing the keycap 3.

[0054] Furthermore, if Figure 4 and Figure 5 As shown, the curved chamfer 332 is smoothly connected to the other parts of the contact surface 331, that is, the curved chamfer 332 and the other parts of the contact surface 331 are a whole curved surface, which can further improve the comfort of the user pressing the keycap 3. It can be understood that the curved chamfer 332 is convex in the direction away from the bottom plate 2, so the contact surface 331 is a curved surface convex in the direction away from the bottom plate 2.

[0055] In some embodiments, Figure 4 As shown, the pressing portion 33 is protruded from the outer surface of the housing 1. The pressing portion 33 is protruded from the outer surface of the housing 1, so that the user can more easily feel the pressing portion 33, and the user can quickly press the keycap 3.

[0056] In some embodiments, Figure 3 and Figure 4As shown, a boss 333 is provided on the side of the pressing part 33 facing the bottom plate 2. The boss 333 is used to trigger the switch 21. The switch 21 is usually relatively small. For example, the height of the tactile switch 21 is usually about 2 mm, and there are usually other parts on the bottom plate 2 with a height greater than 2 mm, resulting in a relatively large gap between the bottom plate 2 and the housing 1. Therefore, it is necessary to press down the pressing part 33 by a relatively large stroke to trigger the switch 21. By providing the boss 333, the gap between the pressing part 33 and the switch 21 is reduced, and even the pressing part 33 directly contacts the switch 21, thereby shortening the stroke required for the pressing part 33 to trigger the switch 21 and making it easier for the user to trigger the switch 21.

[0057] In some embodiments, the boss 333 is elastic, which can reduce the damage of the pressing part 33 to the switch 21, and at the same time reduce the vibration transmitted to the pressing part 33 when the switch 21 is triggered, reduce noise and improve the feel of pressing the keycap 3. Further, the pressing part 33 is elastic, that is, the entire pressing part 33 is set to be elastic. When the pressing part 33 contacts the user's finger, it can deform, reduce the pressure between the center of the finger belly and the pressing part 33, and improve the comfort of the user's finger when pressing the pressing part 33. Optionally, the pressing part 33 is made of silicone or rubber.

[0058] In some embodiments, as Figure 5 shown, the pressing part 33 is provided with a light-transmitting area 334. The light-transmitting area 334 is used for the light inside the housing 1 to pass through the pressing part 33 to the outside of the housing 1; when observed along the first direction X, the shape of the light-transmitting area 334 includes at least one of characters, symbols and patterns. When observed along the first direction X, the projection of the light-transmitting area 334 is located within the projection of the contact surface 331.

[0059] The light inside the housing 1, such as the light of an LED lamp, can pass through the light-transmitting area 334 to the outside of the housing 1; in the eyes of the user, there is a light-emitting light-transmitting area 334 on the pressing part 33, and the light-emitting light-transmitting area 334 shows characters, symbols or patterns, which is convenient for the user to know the function when pressing the keycap 3 and is also convenient for the user to perceive the position of the keycap 3 at night. Among them, the characters can be the common text identifiers of the keys, such as "POWER", "SET", "LIGHT", etc.; the symbols can be the common symbol identifiers of the keys, such as the power symbol, the light symbol and the setting symbol, etc.; the patterns can be the patterns formed by lines, such as the pattern of a battery, the pattern of a lamp and the pattern of a gear, etc.

[0060] In some embodiments, the pressing portion 33 has light transmissivity, and a light-shielding layer is provided on the side of the pressing portion 33 facing away from the bottom plate 2. The light-shielding layer is removed from or not provided on the light-transmitting area 334 to achieve the above-mentioned light-transmitting area 334. Optionally, the light-shielding layer is paint, and the paint can be sprayed on the pressing portion 33 by spraying. After the spraying is completed, the paint on the light-transmitting area 334 can be removed by laser engraving. The process is simple and is beneficial to reducing the manufacturing cost of the light-transmitting area 334.

[0061] For the above-mentioned elastic portion 32 and the supporting portion 31, in some embodiments, such as Figure 5 shown, both the elastic portion 32 and the supporting portion 31 are annular. The outer ring edge of the elastic portion 32 is connected to the supporting portion 31, and the inner ring edge of the elastic portion 32 is connected to the pressing portion 33. The annular elastic portion 32 connecting the supporting portion 31 and the pressing portion 33 can not only enhance the connection strength between the supporting portion 31 and the pressing portion 33, but also increase the elasticity of the keycap 3 to improve the pressing feel of the keycap 3. In addition, when pressing the pressing portion 33, the elastic portion 32 uniformly provides a rebounding force around the pressing portion 33, so that the pressing portion 33 is not easily tilted and shaken, improving the pressing feel of the keycap 3.

[0062] In some embodiments, the elastic portion 32 is circular, and the plane where the elastic portion 32 is located is perpendicular to the first direction X.

[0063] In some embodiments, the supporting portion 31 has elasticity. The supporting portion 31 is located between the housing 1 and the bottom plate 2, and the supporting portion 31 will contact the bottom plate 2 and the housing 1. By setting the supporting portion 31 to have elasticity, damage to the supporting portion 31, the bottom plate 2 and the housing 1 can be reduced, and noise generated by collision or friction between the supporting portion 31 and the bottom plate 2 and the housing 1 can also be reduced.

[0064] In some embodiments, such as Figure 4 shown, the supporting portion 31 is clamped between the bottom plate 2 and the housing 1. When installing the keycap 3, only the pressing portion 33 needs to be placed in the first hole 11, and then the bottom plate 2 is connected to the inner side of the housing 1. There is no need to additionally provide a fixing member to fix the keycap 3 to the housing 1, which is beneficial to simplifying the installation steps of the keycap 3 and improving the assembly efficiency of the key structure 100. Among them, when the supporting portion 31 has elasticity, problems such as the supporting portion 31 being loose after the assembly of the key structure 100 or the supporting portion 31 squeezing and bending the bottom plate 2 and the housing 1 due to manufacturing tolerances can be improved, reducing the assembly difficulty of the key structure 100.

[0065] In some embodiments, the keycap 3 is integrally formed. By manufacturing the keycap 3 through an integral forming process, the manufacturing cost of the keycap 3 can be reduced, and the connection strength between the supporting portion 31, the elastic portion 32, and the pressing portion 33 can also be improved, extending the service life of the keycap 3. Optionally, the keycap 3 is made of silicone or rubber material, preferably silicone material with light transmissivity.

[0066] In some embodiments, as Figure 3 and Figure 4 shown, on one side of the housing 1 facing the bottom plate 2, there is a ring wall 14. The ring wall 14 surrounds the first hole 11. At least part of the supporting portion 31 is disposed in the space formed by the surrounding of the ring wall 14. When observed along the first direction X, the shape and size of the outer contour of the supporting portion 31 are adapted to the shape and size of the space surrounded by the ring wall 14. That is, along the first direction X, the shape and size of the cross-section of the supporting portion 31 are the same as the shape and size of the cross-section of the space surrounded by the ring wall 14, and the supporting portion 31 can slide along the first direction X within the ring wall 14; the ring wall 14 prevents the supporting portion 31 from moving relative to the housing 1 perpendicular to the first direction X, and can limit the position of the keycap 3 during the assembly of the key structure 100, facilitating the assembly of the key structure 100. It can also improve the problem that the keycap 3 runs off relative to the first hole 11 when the pressing portion 33 is pressed to disengage from the first hole 11 during the pressing process of the keycap 3, and enhance the working stability of the key structure 100.

[0067] In some embodiments, as Figure 3 and Figure 4 shown, a groove 141 is provided on the inner side of the ring wall 14. The groove 141 extends along the first direction X. The supporting portion 31 is provided with a convex portion 311, and at least part of the convex portion 311 is disposed in the groove 141. By providing the convex portion 311 and the groove 141, when installing the keycap 3 on the housing 1, the direction of the keycap 3 can be defined, and the problem of incorrect installation angle of the keycap 3 around the first direction X can be improved. During the use of the key structure 100, it can also prevent the keycap 3 from rotating relative to the housing 1 around the first direction X.

[0068] In a second aspect, an embodiment of the present application provides an energy storage device (not shown). The energy storage device includes the key structure 100 as described in any one of the above. The structural features and beneficial effects of the energy storage device having the key structure 100 will not be elaborated here. The energy storage device can be an energy storage power source, an energy storage cabinet, etc.

[0069] In some other embodiments, the key structure 100 can also be applied to computing devices, media devices, transportation means, lighting appliances, entertainment devices, power tools, etc.

[0070] The key structure 100 and the energy storage device according to the embodiments of the present application. The keycap 3 realizes resilience through its own elastic part 32, which can increase the pressing force and resilience force of the keycap 3, and improve the pressing feel of the keycap 3; there is no need to set an additional elastic arm, which simplifies the installation steps of the keycap 3 and improves the assembly efficiency of the key structure 100. The light-transmitting area 334 of the pressing part 33 can display characters, symbols or patterns, which is convenient for users to know the functions when the keycap 3 is pressed, and is also convenient for users to perceive the position of the keycap 3 at night. The keycap 3 can be integrally formed, which reduces the manufacturing cost of the keycap 3, improves the connection strength between the supporting part 31, the elastic part 32 and the pressing part 33, and extends the service life of the keycap 3.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above. For the sake of brevity, they are not provided in detail; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
