DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The key structure and operating device provided by the utility model are described in detail below in conjunction with the embodiments.

[0028] See also Figures 1 to 3 , Figure 1 This is an exploded schematic diagram of an embodiment of the key structure of the present application; Figure 2 It is a first partial cross-sectional schematic diagram of an embodiment of the key structure of the present application; Figure 3 It is a second partial cross-sectional schematic diagram of an embodiment of a key structure of the present application. The present application provides a key structure 10. The key structure 10 can be triggered smoothly and without shaking, has a moderate operating stroke, and a light operating force, thereby improving the user's operating experience. The operating stroke is defined as the stroke of the keycap 12 from the initial state to the trigger signal. Among them, if the operating stroke is too long, it is easy to cause operating fatigue and poor hand feel; if the operating stroke is too short, it is easy to cause accidental touch without hand feel. The operating force is defined as the force of triggering the keycap 12, and the size of the operating force directly affects the user's operating experience. Among them, the smaller the operating force, the easier it is to operate.

[0029] In some embodiments, the key structure 10 includes a housing 11, a keycap 12, a lifting assembly 13, and a switch 14. The housing 11 can be an operating housing in an operating device. The number of keycaps 12, lifting assemblies 13, and switch assemblies 14 can be one, two, three, or more than four. For example, in this embodiment, the number of keycaps 12, lifting assemblies 13, and switch assemblies 14 is four. The lifting assembly 13 is lifted and lowered between the housing 11 and the keycap 12 along a first direction X. For example, the lifting assembly 13 moves upward or downward along the first direction X. The first direction X can be, but is not limited to, a vertical direction.

[0030] The lifting assembly 13 includes a first lifting bracket 131 and a second lifting bracket 132. The first end 131a of the first lifting bracket 131 and the third end 132a of the second lifting bracket 132 are close to the keycap 12; the second end 131b of the first lifting bracket 131 and the fourth end 132b of the second lifting bracket 132 are close to the shell 11. The first lifting bracket 131 and the second lifting bracket 132 are cross-arranged; at the same time, a pivot point 134 is formed between the first lifting bracket 131 and the second lifting bracket 132; in addition, the first lifting bracket 131 and the second lifting bracket 132 are pivotally connected. That is, the first lifting bracket 131 and the second lifting bracket 132 can rotate relative to each other. The above-mentioned first lifting bracket 131 and the second lifting bracket 132 cooperate with each other, which can make the keycap 12 in the key structure 10 more stable during the triggering process and reduce shaking.

[0031] The second lifting bracket 132 is provided with a pressing portion 133. The pressing portion 133 is detachably connected or fixedly connected to the second lifting bracket 132. As in the present embodiment, the pressing portion 133 is integrally formed with the second lifting bracket 132. The pressing portion 133 is located below the pivot point 134; at the same time, the pressing portion 133 is offset from the pivot point 134. The switch member 14 and the pressing portion 133 are releasably abutted. For example, the pressing portion 133 abuts against the switch member 14; or, the pressing portion 133 and the switch member 14 are released from abutment.

[0032] It can be inferred from the lever principle that the operating force of the keycap 12 and the operating force of the switch 14 are proportionally reduced, while the operating stroke is proportionally enlarged, so as to achieve changes in the operating force and the operating stroke, so that the operating stroke in the key structure 10 is moderate and the operating force is relatively light. The moderate operating stroke can be greater than or equal to 0.8mm and less than or equal to 1.2mm. For example, the operating stroke can be but not limited to 0.8mm, 0.9mm, 0.97mm, 1mm, 1.13mm, 1.2mm, etc. The operating force with relatively light operating force can be less than or equal to 30gf.

[0033] When external force acts on the keycap 12, the keycap 12 acts on the first end 131a of the first lifting bracket 131 and the third end 132a of the second lifting bracket 132, and the first lifting bracket 131 and the second lifting bracket 132 rotate relatively, and the first lifting bracket 131 and the second lifting bracket 132 both move downward along the first direction X, so that the pressing portion 133 abuts against the switch 14. When the external force on the keycap 12 is released, the switch 14 is in an off state, and the first lifting bracket 131 and the second lifting bracket 132 move upward along the first direction X under the action of the switch 14; at the same time, the first lifting bracket 131 and the second lifting bracket 132 act on the keycap 12 to restore the keycap 12 to its original state.

[0034] By combining the key cap 12 , the first lifting bracket 131 , the second lifting bracket 132 , the pressing portion 133 and the switch member 14 , the key structure 10 can be triggered smoothly without shaking, with a moderate operating stroke and light operating force, thereby improving the user's operating experience.

[0035] See also Figure 4 and Figure 5 , Figure 4 It is a structural schematic diagram of the lifting component in the key structure of the present application; Figure 5 Schematic diagram of the explosion of the lifting component in the key structure of the present application. Figures 1 to 3In some embodiments, the pivot point 134 is formed between the middle of the first lifting bracket 131 and the middle of the second lifting bracket 132, that is, the middle of the first lifting bracket 131 and the middle of the second lifting bracket 132 are pivotally connected. By defining the position of the pivot point 134, not only the first lifting bracket 131 and the second lifting bracket 132 can be smoothly triggered to descend and ascend without shaking, thereby improving the user's operating experience, but also the keycap 12 can be within a suitable size range, reducing the space occupied by the keycap 12, thereby making the key structure 10 more compact.

[0036] The lifting assembly 13 is lifted and lowered between the housing 11 and the keycap 12. The lifting assembly 13 may be directly connected between the housing 11 and the keycap 12. Alternatively, the lifting assembly 13 is indirectly lifted and lowered between the housing 11 and the keycap 12 through other structures, and the lifting assembly 13 can be lifted and lowered along the first direction X, and its specific structure is not limited.

[0037] In a specific embodiment, the lifting assembly 13 is directly connected between the shell 11 and the keycap 12. For example, the first lifting bracket 131 is connected between the shell 11 and the keycap 12. The second lifting bracket 132 is connected between the shell 11 and the keycap 12. In the above manner, not only can the keycap 12 directly trigger the lifting assembly 13, the triggering is more stable and the shaking is reduced; the operation force is lighter and more labor-saving; at the same time, the number of parts is reduced, saving costs; in addition, the overall thickness of the key structure 10 can be reduced. Among them, the connection method between the two ends of the first lifting bracket 131 and the shell 11 and the keycap 12, and the connection method between the two ends of the second lifting bracket 132 and the shell 11 and the keycap 12 are not limited here, and it is sufficient to realize the lifting of the first lifting bracket 131 and the second lifting bracket 132 along the first direction X.

[0038] Specifically, the keycap 12 includes a first keycap mounting portion 121. The third end 132a of the second lifting bracket 132 moves to the first keycap mounting portion 121 along the second direction Y. During the upward or downward movement of the lifting assembly 13 along the first direction X, the third end 132a of the second lifting bracket 132 can move relative to the first keycap mounting portion 121 along the second direction Y. The first keycap mounting portion 121 can limit the movement trajectory of the third end 132a of the second lifting bracket 132, improve the stability of the lifting movement of the lifting assembly 13, and reduce shaking. The above-mentioned second direction Y is perpendicular to the first direction X. When the first direction X can be but is not limited to a vertical direction, the second direction Y can be but is not limited to a horizontal direction. The vertical direction and the horizontal direction are arranged perpendicularly.

[0039] Further, the first keycap mounting portion 121 is provided with a keycap groove 1211. The keycap groove 1211 is extended along the second direction Y. The third end 132a of the second lifting bracket 132 moves in the keycap groove 1211 along the second direction Y. During the upward or downward movement of the lifting assembly 13 along the first direction X, the third end 132a of the second lifting bracket 132 can move leftward or rightward relative to the keycap groove 1211 along the second direction Y. Further, the keycap groove 1211 is an elliptical hole or a rectangular hole. The elliptical or rectangular hole can limit the movement stroke of the third end 132a of the second lifting bracket 132.

[0040] See also Figure 6 , Figure 6 It is a schematic diagram of the structure of the shell in the key structure of the present application. Figures 1 to 5 Similarly, the housing 11 includes a first housing mounting portion 111. The second end 131b of the first lifting bracket 131 moves to the first housing mounting portion 111 along the second direction Y. When the lifting assembly 13 moves upward or downward along the first direction X, the second end 131b of the first lifting bracket 131 can move relative to the first housing mounting portion 111 along the second direction Y. The first housing mounting portion 111 can limit the movement trajectory of the second end 131b of the first lifting bracket 131, improve the lifting and lowering stability of the lifting assembly 13, and reduce shaking. The second direction Y is perpendicular to the first direction X.

[0041] Further, the first housing mounting portion 111 forms a limiting groove 1111. The limiting groove 1111 is extended along the second direction Y. The second end 131b of the second lifting bracket 132 moves in the limiting groove 1111 along the second direction Y. When the lifting assembly 13 moves upward or downward along the first direction X, the second end 131b of the first lifting bracket 131 can move leftward or rightward along the second direction Y relative to the limiting groove 1111.

[0042] In some embodiments, the keycap 12 includes a second keycap mounting portion 122. The first end 131a of the first lifting bracket 131 is clamped on the second keycap mounting portion 122; at the same time, the first lifting bracket 131 is pivoted on the second keycap mounting portion 122. Through the above method, it is not only convenient to install the first lifting bracket 131 on the second keycap mounting portion 122, but also can improve the stability of the first end 131a of the first lifting bracket 131 installed on the second keycap mounting portion 122, thereby improving the stability of the lifting assembly 13 and reducing shaking; at the same time, it can also make the first lifting bracket 131 rotate a certain angle relative to the keycap 12 to reduce the occurrence of interference problems.

[0043] Similarly, the housing 11 includes a second housing mounting portion 112. The fourth end 132b of the second lifting bracket 132 is clamped on the second housing mounting portion 112; at the same time, the fourth end 132b of the second lifting bracket 132 is pivoted on the second housing mounting portion 112. Through the above method, it is not only convenient to install the second lifting bracket 132 on the second housing mounting portion 112, but also the stability of the fourth end 132b of the second lifting bracket 132 installed on the second housing mounting portion 112 can be improved, thereby improving the lifting stability of the lifting assembly 13 and reducing shaking; at the same time, the second lifting bracket 132 can also be rotated at a certain angle relative to the housing 11 to reduce the occurrence of interference problems.

[0044] In some embodiments, the keycap 12 also includes a keycap body (not shown in the figure). The keycap body and the first keycap mounting portion 121 are fixedly connected or detachably connected. As in the present embodiment, the keycap body and the first keycap mounting portion 121 are integrally connected. The keycap body and the second keycap mounting portion 122 are fixedly connected or detachably connected. As in the present embodiment, the keycap body and the second keycap mounting portion 122 are integrally connected. Among them, the first keycap mounting portion 121 and the second keycap mounting portion 122 are both arranged on the keycap 12, and the first keycap mounting portion 121 and the second keycap mounting portion 122 are arranged relative to each other.

[0045] In some embodiments, at the pivot point 134, one of the first lifting bracket 131 and the second lifting bracket 132 is provided with a pivot shaft 1341. The other of the first lifting bracket 131 and the second lifting bracket 132 is provided with a pivot hole 1342. The pivot shaft 1341 pivots on the pivot hole 1342, so that the first lifting bracket 131 and the second lifting bracket 132 can rotate relative to each other, which is not only simple in structure but also easy to implement.

[0046] In one specific embodiment, the first lifting bracket 131 is provided with a pivot shaft 1341, and the second lifting bracket 132 is provided with a pivot hole 1342, and the pivot shaft 1341 pivots on the pivot hole 1342. In another specific embodiment, the first lifting bracket 131 is provided with a pivot hole 1342, and the second lifting bracket 132 is provided with a pivot shaft 1341, and the pivot shaft 1341 pivots on the pivot hole 1342. The above-mentioned pivot shaft 1341 and the pivot hole 1342 are extended along the third direction Z so that the lifting component 13 can move up and down along the first direction X. Among them, the third direction Z is perpendicular to the first direction X; at the same time, the third direction Z is perpendicular to the second direction Y. For example, the third direction Z can be but not limited to the front-back direction.

[0047] In some implementations, the first lifting bracket 131 includes a first lifting body 1311 and two first lifting parts 1312. The two first lifting parts 1312 are arranged at one end of the first lifting body 1311. The first lifting body 1311 and the two first lifting parts 1312 are detachably connected or fixedly connected.

The two second lifting parts 1322 are arranged at one end of the second lifting body 1321.

[0048] Among them, a pivot point 134 is formed between the first lifting part 1312 and the corresponding second lifting part 1322 and they are pivotally connected. The relative connection between the two first lifting parts 1312 and the two second lifting parts 1322 not only improves the stability of the up and down movement of the lifting assembly 13 and reduces shaking, but also improves the strength of the lifting assembly 13 itself, and also improves the connection strength between the first lifting part 1312 and the housing 11, and the connection strength between the second lifting part 1322 and the keycap 12.

[0049] In some embodiments, the first lifting bracket 131 further includes two third lifting parts 1315. The two third lifting parts 1315 are disposed at the other end of the first lifting body 1311. The first lifting body 1311 and the two third lifting parts 1315 are detachably connected or fixedly connected. As in the present embodiment, the first lifting body 1311 and the two third lifting parts 1315 are integrally connected. Through the two third lifting parts 1315, not only the stability of the up and down movement of the lifting assembly 13 is improved and the shaking is reduced, but also the strength of the lifting assembly 13 itself can be improved, and at the same time, the connection strength between the third lifting parts 1315 and the keycap 12 can be improved.

[0050] In some embodiments, a first end 131a of the first lifting bracket 131 is provided with a first rotating shaft 1313.
