Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a key structure, keyboard, and electronic device. Background Technology

[0002] Keyboard input is the primary means of information input and is used frequently. Electronic devices such as computers, mobile phones, and game consoles are all equipped with keyboards. Currently, the market has an increasing demand for thinner and lighter electronic devices, and the thickness of the keyboard directly affects the overall thickness of the electronic device. However, keyboards in related technologies still face technical challenges in achieving sufficient thinness and lightness. Summary of the Invention

[0003] This application provides a key structure, keyboard, and electronic device to improve the technical problem of keyboards not being thin and light enough in related technologies.

[0004] To achieve the above objectives, the embodiments of this application provide the following solutions:

[0005] On one hand, a key structure is provided, including: a keycap, a first bracket, a second bracket, and a base plate. The first bracket and the second bracket are rotatably connected. The rotation axis of the first bracket relative to the second bracket is a first axis, located between a first end and a second end of the first bracket. The first axis is also located between a first end and a second end of the second bracket. Both the first end of the first bracket and the first end of the second bracket are connected to the keycap. The base plate includes a body portion, a first hook portion, and a second hook portion. The first hook portion and the second hook portion are located on the side of the body portion facing the keycap. The body portion has a first receiving hole. Both the first hook portion and the second hook portion are adjacent to the edge of the first receiving hole. Part of the second end of the first bracket and part of the second end of the second bracket are located within the first receiving hole, and the second end of the first bracket is connected to the first hook portion, and the second end of the second bracket is connected to the second hook portion.

[0006] With the above configuration, since the first bracket and the second bracket can extend into the first receiving hole of the base plate, it is beneficial to reduce the space occupied by the first bracket and the second bracket in the thickness direction of the button structure, thereby reducing the thickness of the button structure and achieving the thinning of the button structure.

[0007] In some embodiments, when the button structure is in the pop-up state: in a first direction, the second end of the first bracket contacts the first limiting wall of the first receiving hole, and the second end of the second bracket contacts the second limiting wall of the first receiving hole; the first limiting wall and the second limiting wall are located between the second ends of the first bracket and the second end of the second bracket; wherein, the first direction is the length direction of the keycap, and the first direction intersects the first axis. With the above configuration, when the button structure is in the pop-up state, the first limiting wall of the first receiving hole can limit the first shaft portion, thereby preventing the second end of the first bracket from rotating counterclockwise relative to the first axis, and thus preventing the first end of the first bracket from rotating counterclockwise relative to the first axis; the second limiting wall of the second receiving hole can limit the second shaft portion, thereby preventing the second end of the second bracket from rotating clockwise relative to the first axis, and thus preventing the first end of the second bracket from rotating clockwise relative to the first axis.

[0008] In some embodiments, the second end of the first bracket includes a first shaft portion, and the first hook portion includes a first part and a second part disposed along a second direction. The first part is connected between the body portion and the second part, and the second part covers a portion of the first receiving hole. The first shaft portion and the first part are spaced apart in the first direction, and the first shaft portion and a portion of the second part overlap and contact each other in the second direction. The second end of the second bracket includes a second shaft portion, and the second hook portion includes a third part and a fourth part disposed along the second direction. The third part is connected between the body portion and the fourth part, and the fourth part covers a portion of the first receiving hole. The second shaft portion and the third part are spaced apart in the first direction, and the second shaft portion and a portion of the fourth part overlap and contact each other in the second direction. Wherein, the first direction is the length direction of the keycap and is perpendicular to the first axis, and the second direction is the thickness direction of the keycap. With the above settings, when the button is in the pop-up state, the first shaft and the first part are prevented from contacting each other, thereby preventing the first part of the first hook from limiting the second end of the first bracket and preventing the positional accuracy of the second end of the first bracket from decreasing; thereby preventing the second shaft and the third part from contacting each other, thereby preventing the third part of the second hook from limiting the second end of the second bracket and preventing the positional accuracy of the second end of the second bracket from decreasing, which is beneficial to improving the lifting accuracy of the button structure and the pressing feel.

[0009] In some embodiments, the first limiting wall of the first receiving hole includes a first hole wall and a second hole wall, which are arranged along a third direction. A first portion is adjacent to the second hole wall, and in a first direction, the distance between the first shaft portion and the second hole wall is greater than the distance between the first shaft portion and the first hole wall. The second limiting wall of the first receiving hole includes a third hole wall and a fourth hole wall, which are arranged along a third direction and are adjacent to each other. In a first direction, the distance between the second shaft portion and the fourth hole wall is greater than the distance between the second shaft portion and the third hole wall. The third direction is parallel to the first axis, the first direction is the length direction of the keycap, and the first direction is perpendicular to the first axis. With the above configuration, when the key is in the pop-up state, the first shaft portion and the first hole wall are in contact, and the first shaft portion and the second hole wall are spaced apart; the second shaft portion and the third hole wall are in contact, and the second shaft portion and the fourth hole wall are spaced apart.

[0010] In some embodiments, when the button structure is in the pop-up state: in a first direction, the first shaft portion contacts the first hole wall, the first shaft portion is spaced apart from the second hole wall, the second shaft portion contacts the third hole wall, and the first shaft portion is spaced apart from the fourth hole wall. Through these arrangements, when the button is in the pop-up state, contact between the first shaft portion and the first part is avoided, thereby preventing the first part of the first hook portion from limiting the second end of the first bracket and preventing a decrease in the positional accuracy of the second end of the first bracket; contact between the second shaft portion and the third part is also avoided, thereby preventing the third part of the second hook portion from limiting the second end of the second bracket and preventing a decrease in the positional accuracy of the second end of the second bracket. This improves the lifting accuracy and pressing feel of the button structure.

[0011] In some embodiments, when the key structure is in a compressed state: in a first direction, the second end of the first bracket contacts the wall of the first receiving hole, and the second end of the second bracket is spaced apart from the wall of the first receiving hole. The first direction is the length direction of the keycap and is perpendicular to the first axis. This arrangement prevents the second end of the first bracket from moving relative to the first hook portion in the first direction, ensuring that the second end of the first bracket remains in contact with the first limiting wall of the first receiving hole. Since the first hook portion and the first shaft portion are also in contact in the second direction, the second end of the first bracket can be rotatably connected to the first hook portion, allowing the first shaft portion to rotate relative to the base plate. During the transition from the pop-up state to the retracted state, the second shaft portion can move relative to the second hook portion along the first direction, and the distance between the second shaft portion and the second hook portion in the first direction increases, allowing the second shaft portion to move relative to the base plate along the first direction.

[0012] In some embodiments, a buffer plate is further included, located on the side of the base plate near the keycap. The buffer plate includes a second receiving hole and a first buffer portion and a second buffer portion disposed at the edge of the second receiving hole. A first support and a second support are disposed through the second receiving hole. In a second direction, the keycap and a portion of the first buffer portion overlap, and the keycap and a portion of the second buffer portion overlap. The second direction is the thickness direction of the keycap. The first and second buffer portions can absorb the impact force from pressing the keycap, thereby helping to alleviate the impact of the key pressing structure on the user's fingers.

[0013] In some embodiments, the base plate further includes clearance holes, with a portion of the first buffer portion and a portion of the second buffer portion covering the clearance holes. This arrangement provides clearance space for the bending deformation of the first and second buffer portions, which helps to further reduce the thickness of the button structure.

[0014] In some embodiments, the first buffer portion has a first protrusion on the side facing the keycap, and the second buffer portion has a second protrusion on the side facing the keycap. By providing the first and second protrusions, it is beneficial to further improve the ability of the first and second buffer portions to absorb impact, thereby further mitigating the impact of the key pressing structure on the user's fingers.

[0015] In some embodiments, the keycap includes a keycap body and an edge portion located at the edge of the keycap body. The edge portion overlaps with a first protrusion along a second direction, and the edge portion overlaps with a second protrusion along the second direction. The second direction is the thickness direction of the keycap. With this configuration, when the edge of the keycap is tilted, the first and second protrusions can dampen the edge of the keycap, preventing the edge of the keycap from directly contacting a hard structure and causing impact to the fingers. This improves the ease of maintenance of the conductive film and extends the service life of the elastic element.

[0016] In some embodiments, in the thickness direction of the keycap, neither the first support nor the second support overlaps with the first buffer portion, and / or neither the first support nor the second support overlaps with the second buffer portion. This arrangement ensures that the first and second buffer portions do not affect the thickness of the key structure, thereby facilitating the reduction of the key structure's thickness.

[0017] In some embodiments, the key structure further includes a conductive film and an elastomer. The conductive film is located on the side of the base plate opposite to the keycap, and the elastomer penetrates the base plate, positioned between the conductive film and the keycap. The conductive film does not require corresponding clearance holes, thus preventing moisture from entering the conductive film through these holes, which improves its waterproof performance. Furthermore, since the conductive film does not require clearance holes, it also allows for greater wiring space for the conductive wires, making wiring easier.

[0018] On the other hand, a keyboard is also provided, which includes: a plurality of key structures as described in any of the above embodiments; and a connecting part, wherein two adjacent key structures are connected by the connecting part.

[0019] On the other hand, an electronic device is also provided, comprising: a motherboard and a keyboard as described in the above embodiments; the motherboard is signal-connected to the keyboard.

[0020] The keyboard and electronic device provided in the embodiments of this application include the key structure as described above, and therefore have all the above-described beneficial effects, which will not be repeated here. Attached Figure Description

[0049] In the following description, the terms "first," "second," etc., are used for ease of description only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0050] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

[0051] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0052] This application provides an electronic device, but the type of electronic device is not limited to this application. Please refer to... Figure 1 , Figure 2 as well as Figure 3 As shown, electronic devices may include desktop computers, laptops, tablets or PDAs for light office work, mobile phones, game consoles, remote controls, etc.

[0053] Continue to refer to Figure 1 , Figure 2 as well as Figure 3 The electronic device 1 includes a motherboard and a keyboard 10, which are connected by signals. The motherboard may include, for example, a printed circuit board (PCB).

[0054] In some embodiments, refer to Figure 1 and Figure 2 The electronic device 1 may also include a display screen 30, which can be connected to the keyboard 10 via a motherboard. Alternatively, the display screen 30 and the keyboard 10 can be wirelessly connected via Bluetooth or other means. The display screen 30 is used to display the input operations of the keyboard 10.

[0055] The display screen 30 may include a liquid crystal display (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., and this application embodiment does not limit it.

[0056] The following description uses only electronic device 1 as an example, which is a laptop computer.

[0057] For example, the keyboard 10 includes a connecting portion and a plurality of key structures 100, with adjacent key structures 100 connected by the connecting portion. In some examples, the electronic device 1 also includes a housing 12, which provides protection and dust protection. The connecting portion is located inside the housing 12, and the housing 12 has a plurality of key holes, with one key structure 100 slidably connected to one key hole.

In some embodiments, the electronic device 1 may also include a battery (not shown), which may be disposed inside the housing 12 and electrically connected to the key structure 100.

[0058] Figure 4 This is a structural diagram of a button structure 100 in a pop-up state, provided in an embodiment of this application. Figure 5 This is a structural diagram of a button structure 100 in a compressed state, provided in an embodiment of this application.

[0059] Reference Figure 4 and Figure 5 In some embodiments, the key structure 100 may include a keycap 110 and a base plate 150. The keycap 110 may move up and down relative to the base plate 150. For example, under the action of pressing pressure, the keycap 110 may move along a direction perpendicular to the base plate 150 and toward the base plate 150 to realize the key function.

[0060] Figure 6 An exploded view of a button structure 100 provided in this application embodiment is shown. (In conjunction with...) Figure 6As shown, the button structure 100 may further include a first bracket 120 and a second bracket 130. The first bracket 120 and the second bracket 130 are rotatably connected. The axis of rotation of the first bracket 120 relative to the second bracket 130 is a first axis L1, located between a first end 129 and a second end 128 of the first bracket. The first axis L1 is also located between the first end 139 and the second end 138 of the second bracket. For example, the first bracket 120 and the second bracket 130 may be connected in a roughly X-shaped structure.

[0061] For ease of explanation, the length direction of the keycap 110 is referred to as the first direction X, which intersects the first axis L1; the thickness direction of the keycap 110 is referred to as the second direction Y; and the width direction of the keycap 110 is referred to as the third direction Z, which is parallel to the first axis L1. For example, the first direction X can be perpendicular to the first axis L1, and the first direction X can also be perpendicular to the plane containing the second direction Y and the third direction Z, with the second direction Y perpendicular to the third direction Z.

[0062] Combination Figure 4 and Figure 6 As shown, the first end 129 of the first bracket and the first end 139 of the second bracket are both connected to the keycap 110. The second ends 128 of the first bracket and the second end 138 of the second bracket can both be connected to the base plate 150, so that the keycap 110 and the base plate 150 can be connected through the first bracket 120 and the second bracket 130. The first bracket 120 and the second bracket 130 can provide support for the keycap 110. The key structure 100 may also include an elastic body 170, which is connected to the keycap 110 and extends through the first bracket 120, the second bracket 130, and the base plate 150.

[0063] In this embodiment, the button structure 100 may include an pop-up state and a retracted state. Specifically, in the second direction Y, when the button structure 100 is in the pop-up state, the distance between the keycap 110 and the base plate 150 is a first distance H1; when the button structure 100 is in the retracted state, the distance between the keycap 110 and the base plate 150 is a second distance H2, where the second distance H2 is less than the first distance H1.

[0064] During the transition of the key structure 100 from the pop-up state to the retracted state: the keycap 110 moves towards the base plate 150 under the action of pressing pressure, and the elastic body 170 undergoes compression deformation. The first end 129 of the first bracket rotates clockwise relative to the first axis L1, and the second end 128 of the first bracket rotates clockwise relative to the first axis L1. At the same time, the first end 139 of the second bracket rotates counterclockwise relative to the first axis L1, and the second end 138 of the second bracket rotates counterclockwise relative to the first axis L1.

[0065] With the above settings, in the second direction Y, the distance between the first end 129 and the second end 128 of the first bracket is reduced, and the distance between the first end 139 and the second end 138 of the second bracket is reduced, so as to reduce the distance between the keycap 110 and the base plate 150.

[0066] Conversely, during the transition of the key structure 100 from the retracted state to the popped state: under the elastic restoring force of the elastic body 170, the keycap 110 moves away from the base plate 150. The first end 129 of the first bracket rotates counterclockwise relative to the first axis L1, and the second end 128 of the first bracket rotates counterclockwise relative to the first axis L1. At the same time, the first end 139 of the second bracket rotates clockwise relative to the first axis L1, and the second end 138 of the second bracket rotates clockwise relative to the first axis L1.

[0067] With the above settings, in the second direction Y, the distance between the first end 129 and the second end 128 of the first bracket is increased, and the distance between the first end 139 and the second end 138 of the second bracket is increased, so as to increase the distance between the keycap 110 and the base plate 150.

[0068] In some embodiments, the base plate 150 may be generally plate-shaped, and the plate-shaped structure can be bent to form a hook for fixing the second end 128 of the first bracket and the second end 138 of the second bracket. However, in some related technologies, since the second end 128 of the first bracket and the second end 138 of the second bracket are both located on the side of the plate-shaped structure facing the keycap 110, the key structure 100 has a large dimension in its thickness direction, which is not conducive to achieving a thinner key structure 100.

[0069] Figure 7 A structural diagram of a first support 120, a second support 130, and a base plate 150 in a pop-out state, provided for an embodiment of this application; Figure 8 A structural diagram of a first support 120, a second support 130, and a base plate 150 in a retracted state, provided for an embodiment of this application; Figure 9 This is a structural diagram of a base plate 150 provided in an embodiment of this application.

[0070] The following reference Figure 7 , Figure 8 as well as Figure 9 In this embodiment of the application, the base plate 150 includes a body portion 156, a first hook portion 152 and a second hook portion 153, with the first hook portion 152 and the second hook portion 153 located on the side of the body portion 156 facing the keycap 110.

[0071] The body portion 156 may be generally plate-shaped. The body portion 156 has a first receiving hole 151. For example, the first receiving hole 151 may be provided through the body portion 156.

[0072] Furthermore, both the first hook portion 152 and the second hook portion 153 can be adjacent to the first receiving hole 151. For example, the first hook portion 152 can be located at the edge of the first receiving hole 151, and the first hook portion 152 can be adjacent to the hole wall of the first receiving hole 151. Similarly, the second hook portion 153 can be located at the edge of the first receiving hole 151, and the second hook portion 153 can be adjacent to the hole wall of the first receiving hole 151.

[0073] In this embodiment of the application, there can be two first receiving holes 151, and the two first receiving holes 151 can be arranged along the third direction Z. Correspondingly, there can be two first hook portions 152 and two second hook portions 153, and the two first hook portions 152 can be arranged along the third direction Z, and the two second hook portions 153 can be arranged along the third direction Z.

[0074] Of course, in some other embodiments, the number of first receiving holes 151 may be one or more, and the number of first hook portions 152 and second hook portions 153 may also be one or more accordingly. This application embodiment does not specifically limit this.

[0075] In some embodiments, the body portion 156, the first hook portion 152, and the second hook portion 153 may be an integral structure. For example, the body portion 156 may be a plate-like structure. The first hook portion 152 and the second hook portion 153 may also be plate-like structures, and the plane containing the first hook portion 152 may be perpendicular to the plane containing the body portion 156. The first hook portion 152 may be formed by bending the body portion 156 located at the edge of the first receiving hole 151.

[0076] Similarly, the plane where the second hook portion 153 is located can be perpendicular to the plane where the body portion 156 is located, and the plane where the second hook portion 153 is located is also parallel to the plane where the first hook portion 152 is located. The second hook portion 153 can also be formed by bending the body portion 156 located at the edge of the first receiving hole 151.

[0077] The above configuration helps to improve the connection reliability between the first hook portion 152 and the body portion 156, as well as the connection reliability between the second hook portion 153 and the body portion 156.

[0078] Reference Figure 7 and Figure 8The second ends 128 of the first bracket and 138 of the second bracket can both be located within the first receiving hole 151, and the second end 128 of the first bracket is connected to the first hook portion 152, while the second end 138 of the second bracket is connected to the second hook portion 153. For example, in a plane parallel to the body portion 156, the second end 128 of the first bracket can overlap with the body portion 156, and the second end 138 of the second bracket can also overlap with the body portion 156.

[0079] The shape of the first receiving hole 151 is not limited in this embodiment, and can be set according to the second end 128 of the first bracket and the second end 138 of the second bracket.

[0080] In this embodiment, the second end 128 of the first bracket is connected to the first hook portion 152. This can be understood as the second end 128 of the first bracket abutting against the first hook portion 152, and the first hook portion 152 limiting the position of the second end 128 of the first bracket. Similarly, the second end 138 of the second bracket is connected to the second hook portion 153. This can be understood as the second end 138 of the second bracket abutting against the second hook portion 153, and the second hook portion 153 limiting the position of the second end 138 of the second bracket.

[0081] Alternatively, in other examples, the second end 128 of the first bracket and the first hook portion 152, and the second end 138 of the second bracket and the second hook portion 153 can be connected together using other connection methods, which are not limited in this embodiment.

[0082] With the above settings, in the thickness direction of the button structure 100 (that is, in the second direction Y), it is beneficial to reduce the space occupied by the first bracket 120 and the second bracket 130, thereby reducing the thickness of the button structure 100 and achieving the thinning of the button structure 100.

[0083] Figure 10 This is a structural diagram of a first support 120 provided in an embodiment of this application. (Refer to...) Figure 10 In some embodiments, the first support 120 may include a first connecting rod 121, a second connecting rod 122, a third connecting rod 123, and a fourth connecting rod 124. The first connecting rod 121, the second connecting rod 122, the third connecting rod 123, and the fourth connecting rod 124 may be connected end to end in sequence, and the four connecting rods together form a first through hole 125. The first connecting rod 121 and the third connecting rod 123 may be arranged parallel to each other, the second connecting rod 122 and the fourth connecting rod 124 may be arranged parallel to each other, and the extension direction of the first connecting rod 121 and the third connecting rod 123 may also be parallel to the first axis L1.

[0084] Figure 11This is a structural diagram of a second support 130 provided in an embodiment of this application. (In conjunction with...) Figure 7 and Figure 11 As shown, the second support 130 can be generally plate-shaped, and the second support 130 is located within the first through hole 125 of the first support 120. The second support 130 can be generally rectangular plate, and the second support 130 can have a second through hole 135, which can communicate with the first through hole 125.

[0085] like Figure 11 As shown, the second support 130 may have two rotating shafts 136, which may be arranged along the third direction Z. Correspondingly, in conjunction with... Figure 10 As shown, the second link 122 and the fourth link 124 may each have a groove 126. The second bracket 130 and the second link 122 can be rotatably connected via a pivot 136 and a groove 126. The second bracket 130 and the fourth link 124 can also be rotatably connected via a pivot 136 and a groove 126, so that the second bracket 130 and the first bracket 120 are rotatably connected. The extension direction of the pivot 136 may be parallel to the third direction Z, and the center line of the pivot 136 is the first axis L1.

[0086] Accordingly, the elastic body 170 can be inserted into the first through hole 125 and the second through hole 135, so that the elastic body 170 passes through the first bracket 120 and the second bracket 130. This arrangement improves the assembly compactness of the button structure 100 and reduces its size.

[0087] Continue to refer to Figure 4 The first end 129 of the first bracket can be slidably connected to the keycap 110, and the first end 139 of the second bracket can be rotatably connected to the keycap 110.

[0088] Figure 12 This application provides a structural diagram of a keycap 110, wherein... Figure 12 This can be the viewing angle from the bottom of the keycap 110 toward the top of the keycap 110.

[0089] Combination Figure 10 and Figure 12 As shown, the first end 129 of the first bracket may include a third link 123. For example, both ends of the third link 123 may be provided with mating blocks 1231. Correspondingly, the side of the keycap 110 facing the first bracket 120 may be provided with two mating grooves 111, and the first link 121 and the keycap 110 may be slidably connected through the mating blocks 1231 and the mating grooves 111. With the above configuration, the first end 129 of the first bracket can be slidably connected to the keycap 110 along the first direction X.

[0090] Combination Figure 11and Figure 12 As shown, the first end 139 of the second bracket may include two mating shafts 1381, which are arranged along the third direction Z. Correspondingly, the keycap 110 may be provided with two mating holes 112 on the side facing the second bracket 130, which are arranged along the third direction Z. The second connecting rod 122 and the keycap 110 can be rotatably connected through the mating shafts 1381 and the mating holes 112. With the above configuration, the first end 139 of the second bracket can be rotatably connected to the keycap 110.

[0091] Continue to refer to Figure 4 , Figure 7 as well as Figure 8 As described in the above embodiments, the second end 128 of the first bracket can be connected to the first hook portion 152 of the base plate 150, and the second end 138 of the second bracket can be connected to the second hook portion 153 of the base plate 150.

[0092] Combination Figure 10 As shown, the second end 128 of the first bracket may include a first connecting rod 121, which may have a first shaft portion 1212. Exemplarily, the first bracket 120 may also have a first mounting hole 1211, which extends through the first bracket 120 and extends along a direction perpendicular to the first connecting rod 121. The first mounting hole 1211 includes a first inner surface 1213 and a second inner surface 1215 spaced apart, wherein the first inner surface 1213 is further away from the first axis L1 than the second inner surface 1215. The first shaft portion 1212 may be disposed on the first inner surface 1213 of the first mounting hole 1211. In some examples, the first shaft portion 1212 and the first bracket 120 may be an integral structure. For example, the first bracket 120 with the first shaft portion 1212 may be machined from a metal sheet.

[0093] Figure 13A for Figure 7 A sectional view of the structure along section line AA from a first-view perspective; Figure 13B for Figure 7 The structure in the image is shown in a sectional view along section line AA from a second perspective. Combined with... Figure 13A and Figure 13B As shown, the second end 128 of the first bracket is located within the first receiving hole 151, and may include a first shaft portion 1212 that can extend into the first receiving hole 151. Correspondingly, a first hook portion 152 can also extend into the first mounting hole 1211. With the above arrangement, in the thickness direction of the button structure 100 (that is, in the second direction Y), it is beneficial to reduce the space occupied by the first hook portion 152, which is beneficial to reduce the thickness of the button structure 100 and improve the assembly compactness of the button structure 100.

[0094] Figure 14 This is an enlarged view of the structure of the first hook portion 152 in a base plate 150 provided in an embodiment of this application. (In conjunction with...) Figure 13A , Figure 13B and Figure 14 As shown, the first hook portion 152 may include a first portion 1521 and a second portion 1523 disposed along the second direction Y. The first portion 1521 is connected between the body portion 156 and the second portion 1523. The first portion 1521 may be adjacent to the edge of the first receiving hole 151, and the second portion 1523 may cover part of the first receiving hole 151. For example, in the first direction X, the size of the first portion 1521 may be smaller than the size of the second portion 1523. The orthographic projection of the first portion 1521 on the body portion 156 is located outside the first receiving hole 151, and the orthographic projection of the second portion 1523 on the body portion 156 is partially located inside the first receiving hole 151.

[0095] Furthermore, the second end 128 of the first bracket is connected to the first hook portion 152 of the base plate 150, which may include: the first shaft portion 1212 and a portion of the second portion 1523 overlapping and contacting each other in the second direction Y. With the above arrangement, the first hook portion 152 can limit the second end 128 of the first bracket in the second direction Y.

[0096] In some embodiments, continue to refer to Figure 13A and Figure 14 As shown, when the button structure 100 is in the pop-up state: in the first direction X, the second end 128 of the first bracket can contact the first limiting wall 158 of the first receiving hole 151. For example, in the first direction X, the first receiving hole 151 may include a first limiting wall 158 disposed towards the first shaft portion 1212. The first limiting wall 158 may be located between the second end 128 of the first bracket and the second end 138 of the second bracket, and the first limiting wall 158 may be perpendicular to the first direction X. The first shaft portion 1212 can contact the first limiting wall 158.

[0097] With the above settings, when the button structure 100 is in the pop-up state, the first limiting wall 158 of the first receiving hole 151 can limit the first shaft portion 1212, thereby preventing the second end 128 of the first bracket from rotating counterclockwise relative to the first axis L1, and thus preventing the first end 129 of the first bracket from rotating counterclockwise relative to the first axis L1.

[0098] Figure 15A for Figure 8 A sectional view of the layout of the structure along the BB section line from a first-view perspective; Figure 15B for Figure 8 The structure in the image is shown in a sectional view along the BB section line from a second perspective. Additionally, refer to... Figure 15A and Figure 15B As shown, when the button structure 100 is in the retracted state: in the first direction X, the second end 128 of the first bracket can contact the first limiting wall 158 of the first receiving hole 151. For example, the first hook portion 152 can also be located inside the first mounting hole 1211, and the first hook portion 152 contacts the second inner surface 1215 of the first mounting hole 1211 in the first direction X.

[0099] With the above configuration, movement of the second end 128 of the first bracket relative to the first hook portion 152 in the first direction X can be avoided, and the second end 128 of the first bracket is always in contact with the first limiting wall 158 of the first receiving hole 151. Since the first hook portion 152 and the first shaft portion 1212 are also in contact in the second direction Y, the second end 128 of the first bracket can be rotatably connected to the first hook portion 152, so that the first shaft portion 1212 can rotate relative to the base plate 150.

[0100] Continue to refer to Figure 13A and Figure 14 In some embodiments, the first limiting wall 158 of the first receiving hole 151 may include a first hole wall 1581 and a second hole wall 1582, and the second hole wall 1582 and the first hole wall 1581 may be arranged along a third direction Z. The first hole wall 1581 and the second hole wall 1582 may both be perpendicular to the first direction X. In the first direction X, the distance between the first shaft portion 1212 and the second hole wall 1582 may be greater than the distance between the first shaft portion 1212 and the first hole wall 1581. With the above settings, when the button is in the pop-up state, the first shaft portion 1212 and the first hole wall 1581 are in contact, and the first shaft portion 1212 and the second hole wall 1582 are spaced apart.

[0101] As described in the above embodiments, the first hook portion 152 can be formed by bending the body portion 156. During the bending process of the body portion 156, the first part 1521 of the first hook portion 152 and the position adjacent to the body portion 156 undergo bending deformation. Since bending deformation is prone to expansion deformation, the dimensional accuracy of the first part 1521 of the first hook is poor.

[0102] The first portion 1521 of the first hook portion 152 can be adjacent to the second hole wall 1582. Since the first shaft portion 1212 and the second hole wall 1582 are spaced apart, when the button is in the pop-up state, the first shaft portion 1212 can also be spaced apart from the first portion 1521. Through this arrangement, when the button is in the pop-up state, contact between the first shaft portion 1212 and the first portion 1521 is avoided, preventing the use of the less precise first portion 1521 to limit the second end 128 of the first bracket. This prevents a decrease in the positional accuracy of the second end 128 of the first bracket, thus improving the lifting accuracy and pressing feel of the button structure 100.

[0103] Furthermore, since the first portion 1521 of the first hook portion 152 is spaced apart from the first shaft portion 1212, the first hook portion 152 does not limit the first shaft portion 1212 in the first direction X, thus reducing the precision requirement for the root of the first hook portion 152. When the first hook portion 152 is formed by bending the body portion 156, the height (dimension along the second direction Y) of the first portion 152 of the first hook portion 152 can be reduced. The root of the first hook portion 152 can be understood as the portion adjacent to the body portion 156.

[0104] The above-mentioned design helps to reduce the torque on the root of the first hook portion 152, thereby reducing the deformation of the first hook portion 152 under the action of the abutting force of the first shaft portion 1212, which helps to further improve the lifting accuracy of the key structure 100. At the same time, since the torque on the root of the first hook portion 152 is reduced, it helps to improve the rigidity of the first hook portion 152, increase the pulling force of the keycap 110, and prevent the keycap 110 from falling off due to fingers getting caught on it.

[0105] Similarly, refer to Figure 11 The second end 138 of the second bracket may include a second shaft portion 1382. Exemplarily, the second bracket 130 may also have a second mounting hole 1384 extending through the second bracket 130, and the second shaft portion 1382 may be disposed on the inner surface of the second mounting hole 1384. In some examples, the second shaft portion 1382 and the second bracket 130 may be an integral structure. For example, the second bracket 130 with the second shaft portion 1382 may be machined from a sheet metal.

[0106] Figure 16A for Figure 7 A sectional view of the layout of the structure along the CC section line from a first-view perspective. Figure 16B for Figure 7 The structure in the image is shown in a sectional view along the CC section line from a second perspective. Combined with... Figure 16A and Figure 16B As shown, the second end 138 of the second bracket is located within the first receiving hole 151, and may include a second shaft portion 1382 that can extend into the first receiving hole 151. Correspondingly, the second hook portion 153 can also extend into the second mounting hole 1384. With the above arrangement, in the thickness direction of the button structure 100 (that is, in the second direction Y), it is beneficial to reduce the space occupied by the second hook portion 153, which is beneficial to reduce the thickness of the button structure 100 and improve the assembly compactness of the button structure 100.

[0107] Figure 17 This is an enlarged view of the structure of the second hook portion 153 in a base plate 150 provided in an embodiment of this application. (In conjunction with...) Figure 16A and Figure 17 As shown, the second hook portion 153 may include a third portion 1531 and a fourth portion 1533 disposed along the second direction Y. The third portion 1531 is connected between the body portion 156 and the fourth portion 1533. The third portion 1531 may be adjacent to the edge of the first receiving hole 151, and the fourth portion 1533 may cover part of the first receiving hole 151. For example, in the first direction X, the size of the third portion 1531 may be smaller than the size of the fourth portion 1533. The orthographic projection of the third portion 1531 on the body portion 156 is located outside the first receiving hole 151, and the orthographic projection of the fourth portion 1533 on the body portion 156 is partially located inside the first receiving hole 151.

[0108] Furthermore, the second end 138 of the second bracket is connected to the second hook portion 153 of the base plate 150, which may include: the second shaft portion 1382 and a portion of the fourth portion 1533 overlapping and contacting each other in the second direction Y. With the above arrangement, the second hook portion 153 can limit the second end 138 of the second bracket in the second direction Y.

[0109] Reference Figure 16A As shown, when the button structure 100 is in the pop-up state: in the first direction X, the second end 138 of the second bracket can contact the second limiting wall 159 of the second receiving hole 146. For example, the second receiving hole 146 may include a second limiting wall 159 disposed towards the second shaft portion 1382, and the second limiting wall 159 may be perpendicular to the first direction X. The second shaft portion 1382 can contact the second limiting wall 159.

[0110] With the above settings, when the button structure 100 is in the pop-up state, the second limiting wall 159 of the second receiving hole 146 can limit the second shaft portion 1382, thereby preventing the second end 138 of the second bracket from rotating clockwise relative to the first axis L1, and thus preventing the first end 139 of the second bracket from rotating clockwise relative to the first axis L1.

[0111] Figure 18A for Figure 8 A sectional view of the layout of the structure along the DD section line from a first-view perspective; Figure 18B for Figure 8 The structure in the image is shown in a sectional view along the DD section line from a second perspective. (Refer to...) Figure 18A and Figure 18BAs shown, when the button structure 100 is in the retracted state: in the first direction X, the second end 138 of the second bracket can be spaced apart from the second limiting wall 159 of the second receiving hole 146. For example, the second hook portion 153 can also be located within the second mounting hole 1384, with the second hook portion 153 and the inner surface of the second mounting hole 1384 spaced apart in the first direction X. With the above configuration, during the transition of the button structure 100 from the pop-up state to the retracted state, the second shaft portion 1382 can move relative to the second hook portion 153 along the first direction X, and the distance between the third portion 1531 of the second shaft portion 1382 and the second hook portion 153 in the first direction X increases, so that the second shaft portion 1382 can move relative to the base plate 150 along the first direction X.

[0112] Continue to refer to Figure 16A and Figure 17 In some embodiments, the second limiting wall 159 of the second receiving hole 146 may include a third hole wall 1591 and a fourth hole wall 1592, which may be arranged along a third direction Z. Both the third hole wall 1591 and the fourth hole wall 1592 may be perpendicular to the first direction X. In the first direction X, the distance between the second shaft portion 1382 and the fourth hole wall 1592 may be greater than the distance between the second shaft portion 1382 and the third hole wall 1591. With the above configuration, when the button is in the pop-up state, the second shaft portion 1382 and the third hole wall 1591 are in contact, and the second shaft portion 1382 and the fourth hole wall 1592 are spaced apart.

[0113] As described in the above embodiments, the second hook portion 153 can be formed by bending the body portion 156. During the bending process of the body portion 156, the third part 1531 of the second hook portion 153 is bent and deformed at the position adjacent to the body portion 156. Since bending deformation is prone to expansion deformation, the dimensional accuracy of the third part 1531 of the second hook portion 153 is poor.

[0114] Furthermore, the third portion 1531 of the second hook portion 153 can be adjacent to the fourth hole wall 1592. Since the second shaft portion 1382 and the fourth hole wall 1592 are spaced apart, when the button is in the pop-up state, the second shaft portion 1382 can also be spaced apart from the third portion 1531. Through this arrangement, when the button is in the pop-up state, contact between the second shaft portion 1382 and the third portion 1531 is avoided, thereby preventing the third portion 1531 of the second hook portion 153 from limiting the second end 138 of the second bracket, preventing a decrease in the positional accuracy of the second end 138 of the second bracket, and improving the accuracy of the lifting height of the button structure 100 and the pressing feel.

[0115] As described in the above embodiments, when the third portion 1531 of the second hook portion 153 is spaced apart from the second shaft portion 1382, the precision requirement for the root of the second hook portion 153 is reduced. When the second hook portion 153 is formed by bending the body portion 156, the height (dimension along the second direction Y) of the third portion 153 of the second hook portion 153 can be reduced. With the above arrangement, it is beneficial to reduce the torque on the root of the second hook portion 153, thereby reducing the deformation of the second hook portion 153 under the action of the abutting force of the second shaft portion 1382, which is beneficial to further improve the lifting accuracy of the key structure 100. At the same time, since the torque on the root of the second hook portion 153 is reduced, it is beneficial to improve the rigidity of the second hook portion 153, increase the pull force of the keycap 110, and prevent the keycap 110 from falling off due to fingers getting caught on it.

[0116] In some other embodiments, the first hook portion 152 may omit the first part 1521, and the second hook portion 153 may omit the third part 1531. This application does not limit the specific structure of the first hook portion 152 and the second hook portion 153.

[0117] Figure 19 An assembly structure diagram of a buffer plate 140 and a base plate 150 provided for an embodiment of this application; Figure 20 An exploded view of the structure of a buffer plate 140 and a base plate 150 provided in an embodiment of this application.

[0118] Combination Figure 4 , Figure 19 and Figure 20 As shown, in some embodiments, the key structure 100 further includes a buffer plate 140. The buffer plate 140 may be located on the side of the base plate 150 near the keycap 110. The buffer plate 140 may include a second receiving hole 146, through which a first bracket 120 and a second bracket 130 are disposed. Exemplarily, the second receiving hole 146 may communicate with the first receiving hole 151, and the second end 128 of the first bracket and the second end 138 of the second bracket may extend into the first receiving hole 151 via the second receiving hole 146.

[0119] Figure 21 This application provides a first buffer section 141 and an application principle diagram of the first buffer section 141. (In conjunction with...) Figure 21As shown, the buffer plate 140 may further include a first buffer portion 141 and a second buffer portion 142 disposed at the edge of the second receiving hole 146 in the second direction Y. The keycap 110 overlaps with a portion of the first buffer portion 141, and the keycap 110 overlaps with a portion of the second buffer portion 142. For example, the buffer plate 140 may be a one-piece molded structure, and the first buffer portion 141 and the second buffer portion 142 may extend from the edge of the second receiving hole 146 into the interior of the second receiving hole 146. The material of the buffer plate 140 may include metal, polyethylene terephthalate (PET), or other materials with good strength and deformability.

[0120] With the above configuration, when the keycap 110 moves towards the base plate 150 until the key structure 100 is in a retracted state, the keycap 110 contacts the first buffer portion 141 and the second buffer portion 142 respectively, and the first buffer portion 141 and the second buffer portion 142 bend and deform under the pressure of the keycap 110. The first buffer portion 141 and the second buffer portion 142 can absorb the impact force from the keycap 110, thereby helping to reduce the impact of pressing the key structure 100 on the user's fingers.

[0121] In some embodiments, neither the first support 120 nor the second support 130 overlaps with the first buffer portion 141 in the second direction Y. Similarly, neither the first support 120 nor the second support 130 overlaps with the second buffer portion 142 in the second direction Y. For example, in the first direction X, the first support 120 and the second support 130 may be a certain distance from the first buffer portion 141, and the first support 120 and the second support 130 may be a certain distance from the second buffer portion 142. With the above arrangement, the first buffer portion 141 and the second buffer portion 142 do not affect the thickness of the button structure 100, thereby facilitating the thinning of the button structure 100.

[0122] Furthermore, in this embodiment, the shape and position of the first buffer portion 141 and the second buffer portion 142 are not specifically limited. The shape and position of the first buffer portion 141 and the second buffer portion 142 can be set according to the requirements of elastic deformation. For example, the width of the first buffer portion 141 (that is, the dimension of the first buffer portion 141 along the third direction Z) is related to the elastic deformation capability of the first buffer portion 141. The elastic deformation capability of the first buffer portion 141 can be improved by reducing the width of the first buffer portion 141. The adjustment of the width of the second buffer portion 142 can refer to the above embodiment, and will not be described in detail here.

[0123] The first buffer portion 141 has a first protrusion 143 on the side facing the keycap 110, and the second buffer portion 142 has a second protrusion 145 on the side facing the keycap 110. For example, in embodiments where the material of the buffer plate 140 includes polyethylene terephthalate, the first protrusion 143 and the second protrusion 145 can be formed by vacuum hot pressing or cold pressing.

[0124] In this embodiment, the position and shape of the first protrusion 143 and the second protrusion 145 are not specifically limited. The position and shape of the first protrusion 143 and the second protrusion 145 can be set according to the shape of the keycap 110.

[0125] By setting the first protrusion 143 and the second protrusion 145, it is beneficial to further improve the ability of the first buffer part 141 and the second buffer part 142 to absorb impact force, thereby further mitigating the impact of the button pressing structure 100 on the user's fingers.

[0126] Accordingly, continue to refer to Figure 21 The keycap 110 includes a keycap 110 body and an edge portion 119 located at the edge of the keycap 110 body. The edge portion 119 overlaps with the first protrusion 143 along the second direction Y, and the edge portion 119 overlaps with the second protrusion 145 along the second direction Y. For example, the edge portion 119 may extend relative to the keycap 110 body in a direction close to the base plate 150, and the edge portion 119 may be referred to as the brim of the keycap.

[0127] When the key structure 100 is in the retracted state, the edge 119 of the keycap 110 can contact the first protrusion 143 and the second protrusion 145 respectively, causing the first buffer portion 141 and the second buffer portion 142 to bend and deform. With the above arrangement, when the edge 119 of the keycap 110 is tilted, the first protrusion 143 and the second protrusion 145 can play a shock-absorbing role on the edge of the keycap 110, preventing the edge 119 of the keycap 110 from directly contacting the hard structure and causing impact to the fingers.

[0128] Furthermore, the base plate 150 may include clearance holes 157, and a portion of the first buffer portion 141 and a portion of the second buffer portion 142 may cover the clearance holes 157. For example, there may be multiple clearance holes 157, wherein some clearance holes 157 may be spaced apart from the first receiving hole 151, and other clearance holes 157 may communicate with the first receiving hole 151, or in other words, other clearance holes 157 may be reused as the first receiving hole 151.

[0129] When the button is in the retracted state, the first buffer portion 141 and the second buffer portion 142 can be bent and deformed into the clearance hole 157. With the above arrangement, the clearance hole 157 can provide clearance space for the bending deformation of the first buffer portion 141 and the second buffer portion 142, which is beneficial to further reduce the thickness of the button structure 100.

[0130] Continue to refer to Figure 4 The key structure 100 may further include a conductive film 160. An elastomer 170 may be located between the conductive film 160 and the keycap 110.

[0131] The conductive film 160 can be electrically connected to the motherboard of the electronic device 1. For example, the conductive film 160 may include a first sub-layer, a second sub-layer, and a third sub-layer stacked in sequence. The first and second sub-layers are provided with conductive lines and button contacts, and the second sub-layer is provided with circular holes corresponding to the button contacts.

[0132] When the key structure 100 is in the pop-up state, the second sub-layer can be used to electrically isolate the first sub-layer and the third sub-layer; when the key structure 100 is in the retracted state, the keycap 110 squeezes the conductive film 160 through the elastic body 170, causing the first sub-layer to deform downward toward the third sub-layer, so that the key contacts of the first sub-layer and the third sub-layer are connected (similar to a switch being turned on), so that the motherboard is electrically connected to the conductive film 160.

[0133] Figure 22 This is a schematic diagram illustrating the application principle of the conductive film 160 provided in this embodiment, located on the side of the base plate 150 near the keycap 110. (Refer to...) Figure 22 In some embodiments, the conductive film 160 may be located on the side of the base plate 150 near the keycap 110. Accordingly, to avoid the first hook portion 152 and the second hook portion 153 of the base plate 150, the conductive film 160 may be provided with corresponding through holes.

[0134] Figure 23 This is a schematic diagram illustrating the application principle of the conductive film 160 provided in this embodiment, located on the side of the base plate 150 opposite to the keycap 110. (Refer to...) Figure 23 In some other embodiments, the conductive film 160 may be located on the side of the base plate 150 opposite to the keycap 110. For example, the conductive film 160 may be adhered to the side of the base plate 150 opposite to the keycap 110.

[0135] Compared to placing the conductive film 160 on the side of the base plate 150 near the keycap 110, the conductive film 160 does not require corresponding through holes for avoidance, thus preventing moisture from entering the conductive film 160 through the through holes and improving its waterproof performance. Furthermore, since the conductive film 160 does not require corresponding through holes, it also allows for more space for the conductive wires, making wiring easier.

[0136] Furthermore, since the conductive film 160 is located on the side of the base plate 150 opposite to the keycap 110, when maintaining or replacing the conductive film 160, it is not necessary to disassemble other components in the key structure 100; the conductive film 160 can simply be peeled off from the base plate 150. This design improves the ease of maintenance for the conductive film 160.

[0137] Furthermore, with the above arrangement, compared to placing the conductive film 160 on the side of the base plate 150 near the keycap 110, the elastic deformation dimension of the elastic element in the second direction Y is increased (e.g., ...) while the thickness of the key mechanism remains unchanged. Figure 23 The elastic deformation dimension D2 of the elastic element is greater than Figure 22 The elastic deformation dimension D1 of the elastic element is beneficial to reducing the compression ratio of the elastic element, which in turn helps to extend the service life of the elastic element.

[0138] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
