DETAILED DESCRIPTION

[0041] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0042] The keyboard generally includes a substrate 2, a key assembly 3 arranged on the substrate 2 and a shell with a key hole. When the substrate 2 is connected to the shell, the substrate 2 and the shell are relatively positioned by a positioning structure 4. The keyboard is large in length, so a larger tolerance is required to ensure that the substrate 2 and the shell can be connected through the positioning structure 4. However, due to the large tolerance, the key assembly 3 located in the key hole is prone to displacement, and even the key assembly 3 interferes with one side of the key hole, affecting the performance of the keyboard. The technical solution of the embodiment of the present disclosure is a technical solution based on dividing the substrate 2 into at least two relatively independent parts through an elastic structure 26 to reduce the required tolerance. The essence of the technical solution of the present disclosure is explained below through specific examples.

[0043] See also Figures 1 to 6 The embodiment of the present disclosure provides a keyboard, including a first shell 1, a substrate 2 and a key assembly 3. The first shell 1 includes a first surface and a second surface opposite to each other. The first shell 1 has a first key hole 11 connecting the first surface and the second surface. The substrate 2 is connected to the first shell 1. The substrate 2 is located on one side of the second surface. The substrate 2 includes a first side 21 and a second side 22 adjacent to each other. The length of the first side 21 is greater than the length of the second side 22. Along the direction of the first side 21, the substrate 2 is divided into at least two parts. The at least two parts of the substrate 2 are respectively positioned relative to the first shell 1 by a positioning structure 4. The two adjacent parts are connected by an elastic structure 26. The elastic structure 26 adjusts the distance between the two adjacent parts by deformation. The substrate 2 can be connected to at least two parts by the elastic structure 26, for example, including a first part 23 and a second part 24. The first part 23 and the second part 24 are connected by the elastic structure 26. The key assembly 3 is connected to the substrate 2. The key assembly 3 is penetrated in the first key hole 11 to protrude from the first surface.

[0044] In the embodiment of the present disclosure, the substrate 2 is divided into at least two parts, and the two adjacent parts are connected by an elastic structure 26. The elastic structure 26 can adjust the distance between the two adjacent parts by deformation, so that the at least two parts are relatively independent within the deformation range of the elastic structure 26, thereby dividing the substrate 2 from a larger-sized whole into at least two relatively independent parts of smaller sizes, and each part can be relatively independently positioned relative to the first shell 1 through the positioning structure 4, so that the tolerance required for the substrate 2 to be connected to the first shell 1 is reduced. The deformation of the elastic structure 26 can compensate for the smaller tolerance of the positioning structure 4, ensure the assembly of the substrate 2 and the first shell 1, and because a smaller tolerance can be adopted, the offset of the key assembly 3 can be improved, so that the key assembly 3 is basically centered in the first key hole 11. At least two parts are connected by the elastic structure 26, so that the substrate 2 retains an integral form while the at least two parts divided into it remain relatively independent within the deformation range of the elastic structure 26, and the tolerance of the positioning structure 4 is compensated by the deformation of the elastic structure 26, so that the offset of the key assembly 3 is improved, and the performance of the keyboard will not be affected.

[0045] In the embodiments of the present disclosure, see Figures 1 to 6 The at least two parts of the substrate 2 may include a first part 23 and a second part 24, and the first part 23 and the second part 24 are connected by an elastic structure 26. The substrate 2 may also be divided into more than two parts, for example, further including a third part 25, and the third part 25 is connected to the second part 24 by an elastic structure 26.

[0046] See also Figures 3 to 6 , assuming that the tolerance of the positioning structure 4 between each part and the first shell 1 is x millimeters, the deformation range of the elastic structure 26 in the direction of the first side 21 is y millimeters, and the deformation of the elastic structure 26 can compensate the cumulative tolerance between the two adjacent parts by y millimeters. If the substrate 2 is a whole and is not divided into at least two parts connected by the elastic structure 26, due to the lack of compensation by the elastic structure 26, the required tolerance of the positioning structure 4 between the first shell 1 is z millimeters, and z needs to be greater than x. The cumulative tolerance is larger, and the key assembly 3 is more likely to be offset than the keyboard disclosed in the present invention.

[0047] In the embodiments of the present disclosure, see Figures 3 to 6 The positioning structure 4 includes a first positioning structure 4 provided on the first housing 1 and a second positioning structure 4 provided on the substrate 2. The first positioning structure 4 and the second positioning structure 4 cooperate to relatively position the first housing 1 and the substrate 2. The first positioning structure 4 and the second positioning structure 4 can be a positioning column 41 and a positioning hole 42 that cooperate with each other. In a specific implementation, the first positioning structure 4 can be a positioning column 41, and the second positioning structure 4 can be a positioning hole 42 that cooperates with the positioning column 41.

[0048] The first positioning structure 4 and the second positioning structure 4 matched between each part of the substrate 2 and the first shell 1 can be at least two groups, each group includes a first positioning structure 4 and a second positioning structure 4 matched therewith. The number of groups of positioning structures 4 between each part and the first shell 1 can be the same or different. For example, the first part 23 has four positioning holes 42, the first shell 1 has four positioning posts 41 matched with the positioning holes 42 on the first part 23, the second part 24 has six positioning holes 42, the first shell 1 has six positioning posts 41 matched with the positioning holes 42 on the second part 24, the third part 25 has four positioning holes 42, and the first shell 1 has four positioning posts 41 matched with the positioning holes 42 on the third part 25.

[0049] In one embodiment, see Figure 3 , the at least two parts into which the substrate 2 is divided include an adjacent first part 23 and a second part 24. The elastic structure 26 includes a first elastic strip 261, which is arranged on the first part 23 of the two adjacent parts, the first elastic strip 261 and the second side 22 meet the parallel condition, and the middle part of the first elastic strip 261 is connected to the second part 24 of the two adjacent parts. The angle between the first elastic strip 261 and the second side 22 does not exceed the first threshold, and the first elastic strip 261 and the second side 22 meet the parallel condition. The first threshold can be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, etc. When the first part 23 and the second part 24 are respectively positioned with the first shell 1 through the positioning structure 4, and the elastic structure 26 is required to compensate for the tolerance, since the middle part of the first elastic strip 261 is connected to the second part 24, the first elastic strip 261 bends, thereby compensating for the accumulated tolerance between the first part 23 and the second part 24.

[0050] In one embodiment, see Figure 4, the at least two parts into which the substrate 2 is divided include an adjacent first part 23 and a second part 24. The elastic structure 26 includes a second elastic strip 262, which is arranged on the second part 24 of the two adjacent parts, the second elastic strip 262 and the second side 22 meet the parallel condition, and the middle part of the second elastic strip 262 is connected to the first part 23 of the two adjacent parts. The angle between the second elastic strip 262 and the second side 22 does not exceed the second threshold, and the second elastic strip 262 and the second side 22 meet the parallel condition. The second threshold can be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, etc. When the first part 23 and the second part 24 are respectively positioned with the first shell 1 through the positioning structure 4, and the elastic structure 26 is required to compensate for the tolerance, since the middle part of the second elastic strip 262 is connected to the first part 23, the second elastic strip 262 bends, thereby compensating for the accumulated tolerance between the first part 23 and the second part 24.

[0051] In one embodiment, see Figure 5 The elastic structure 26 includes a first elastic strip 261 and a second elastic strip 262. The first elastic strip 261 is connected to the first part 23 of the two adjacent parts, and the second elastic strip 262 is connected to the second part of the two adjacent parts. The first elastic strip 261 and the second elastic strip 262 respectively meet the parallel condition with the second side 22. The first elastic strip 261 and the second elastic strip 262 correspond to each other one by one, and the middle part of the first elastic strip 261 is connected to the middle part of the corresponding second elastic strip 262. The parallel condition satisfied by the first elastic strip 261 or the second elastic strip 262 and the second side 22 can be specifically referred to the description of the above embodiment. The first elastic strip 261 and the second elastic strip 262 are arranged relative to each other, which can increase the deformation of the elastic structure 26 and make more compensation for the tolerance.

[0052] In one embodiment, see Figure 6 The elastic structure 26 includes at least two third elastic strips 263, the third elastic strips 263 and the second side 22 meet the parallel condition, and at least two third elastic strips 263 are connected in sequence to form a reciprocating circuitous structure, and the reciprocating circuitous structure can be extended or contracted along the first side 21, and the two ends of the reciprocating circuitous structure are respectively connected to the first part 23 and the second part 24 of the two adjacent parts. The reciprocating circuitous structure formed by the connection of the third elastic strips 263 can be extended or contracted along the first side 21, so as to compensate for the tolerance of the positioning structure 4 between the substrate 2 and the first shell 1, reduce the tolerance required for the positioning structure 4, and improve the offset of the key assembly 3.

[0053] Two adjacent third elastic strips 263 may be connected by a circuitous portion 264, so that at least two third elastic strips 263 are connected end to end in sequence to form a reciprocating circuitous structure. The angle between the third elastic strip 263 and the second side 22 does not exceed a third threshold, and the third elastic strip 263 and the second side 22 meet a parallel condition. The third threshold may be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, 45°, etc. The angles between different reciprocating portions and the second side 22 may be different.

[0054] The shape of the detour portion 264 may be an arc or a broken line.

[0055] In one embodiment, see Figures 3 to 6 , the substrate 2 is divided into at least two parts along the first side 21 direction by the hollow structure, and an elastic structure 26 is formed. In the embodiment of the present disclosure, a hollow structure can be formed on the substrate 2 by engraving or other processes on the basis of an integral body, and the hollow structure divides the substrate 2 into at least two parts along the first direction, and an elastic structure 26 is formed between the two adjacent parts.

[0056] In an exemplary embodiment, a first elastic strip 261 is formed by a carved hollow structure on one side of the first part 23, a second elastic strip 262 opposite to the first elastic strip 261 is formed by a carved hollow structure on one side of the second part 24, and a connecting portion is formed in the middle of the first elastic strip 261 and the second elastic strip 262.

[0057] Alternatively, the third elastic strip 263 is formed between the first portion 23 and the second portion 24 by means of a carved hollow structure.

[0058] In one embodiment, see Figure 2 The substrate 2 has a key installation position 28, each key installation position 28 is connected to a group of key components 3, and the elastic structure 26 is arranged between two key installation positions 28 adjacent to each other in the direction of the first side 21. The substrate 2 is divided into at least two parts by a gap 27 formed by a hollow structure. The elastic structure 26 separates the gap 27 into a discontinuous structure. The key installation position 28 may be provided with a connecting structure, and the connecting structure is used to connect the key component 3 with the substrate 2.

[0059] In one embodiment, the substrate 2 may also be divided into at least two parts along the second side 22, and the at least two parts are connected by an elastic structure 26. By being divided into at least two parts along the first side 21 and the second side 22, the substrate 2 may be divided into smaller sizes in both the length and width directions to reduce the required tolerance.

[0060] See also Figures 7 to 12The embodiment of the present disclosure provides an electronic device, including a second housing 5 and a keyboard structure, wherein the second housing 5 includes a first surface and a second surface opposite to each other, and the second housing 5 has a second key hole 51 connecting the first surface and the second surface. The keyboard structure includes a substrate 2 and a key assembly 3, the substrate 2 is connected to the second housing 5, the substrate 2 is located on one side of the second surface, the substrate 2 includes a first side 21 and a second side 22 adjacent to each other, the length of the first side 21 is greater than the length of the second side 22, and along the direction of the first side 21, the substrate 2 is divided into at least two parts, at least two parts of the substrate 2 and the second housing 5 are respectively positioned relative to each other by a positioning structure 4, and the two adjacent parts are connected by an elastic structure 26, and the elastic structure 26 adjusts the distance between the two adjacent parts by deformation. The substrate 2 can include, for example, a first part 23 and a second part 24 connected by the elastic structure 26, and the first part 23 and the second part 24 are connected by the elastic structure 26. The key assembly 3 is connected to the substrate 2, and the key assembly 3 is penetrated in the second key hole 51 to protrude from the first surface.

[0061] In the embodiment of the present disclosure, the substrate 2 is divided into at least two parts, and the two adjacent parts are connected by an elastic structure 26. The elastic structure 26 can adjust the distance between the two adjacent parts by deformation, so that the at least two parts are relatively independent within the deformation range of the elastic structure 26, thereby dividing the substrate 2 from a larger-sized whole into at least two relatively independent parts of smaller sizes, and each part can be relatively independently positioned relative to the second shell 5 by the positioning structure 4, so that the tolerance required for the substrate 2 to be connected to the second shell 5 is reduced. The deformation of the elastic structure 26 can compensate for the smaller tolerance of the positioning structure 4, ensure the assembly of the substrate 2 and the second shell 5, and because a smaller tolerance can be adopted, the offset of the key assembly 3 can be improved, so that the key assembly 3 is basically centered in the second key position hole 51. At least two parts are connected by the elastic structure 26, so that the substrate 2 retains an integral form while the at least two parts divided into it remain relatively independent within the deformation range of the elastic structure 26, and the tolerance of the positioning structure 4 is compensated by the deformation of the elastic structure 26, so that the offset of the key assembly 3 is improved, and the performance of the keyboard will not be affected.

[0062] The keyboard structure in the electronic device of the embodiment of the present disclosure may have the same or similar structure as the above keyboard embodiment. For example, the substrate 2 of both may have the same structure, and the positioning structure 4 between the substrate 2 and the housing may also be the same. The above keyboard embodiments may be used to understand the electronic device of the embodiment of the present disclosure.

[0063] The electronic device of the embodiment of the present disclosure includes a laptop computer. The second housing 5 may be a housing of a system end of the laptop computer, and the keyboard structure is arranged at the system end.

[0064] In the embodiment of the present disclosure, the substrate 2 can be divided into a first part 23 and a second part 24, and the first part 23 and the second part 24 are connected by an elastic structure 26. The substrate 2 can also be divided into more than two parts, for example, further including a third part 25, and the third part 25 is connected to the second part 24 by an elastic structure 26.

[0065] See also Figures 9 to 12 , assuming that the tolerance of the positioning structure 4 between each part and the first shell 1 is x millimeters, the deformation range of the elastic structure 26 in the direction of the first side 21 is y millimeters, and the deformation of the elastic structure 26 can compensate the cumulative tolerance between the two adjacent parts by y millimeters. If the substrate 2 is a whole and is not divided into at least two parts connected by the elastic structure 26, due to the lack of compensation by the elastic structure 26, the required tolerance of the positioning structure 4 between the first shell 1 is z millimeters, and z needs to be greater than x. The cumulative tolerance is larger, and the key assembly 3 is more likely to be offset than the keyboard disclosed in the present invention.

[0066] In the embodiments of the present disclosure, see Figures 9 to 12 The positioning structure 4 includes a first positioning structure 4 provided on the second housing 5 and a second positioning structure 4 provided on the substrate 2. The first positioning structure 4 and the second positioning structure 4 cooperate to relatively position the second housing 5 and the substrate 2. The first positioning structure 4 and the second positioning structure 4 can be a positioning column 41 and a positioning hole 42 that cooperate with each other. In a specific implementation, the first positioning structure 4 can be a positioning column 41, and the second positioning structure 4 can be a positioning hole 42 that cooperates with the positioning column 41.

[0067] The first positioning structure 4 and the second positioning structure 4 matched between each part of the substrate 2 and the first shell 1 can be at least two groups, each group includes a first positioning structure 4 and a second positioning structure 4 matched therewith. The number of groups of positioning structures 4 between each part and the first shell 1 can be the same or different. For example, the first part 23 has four positioning holes 42, the first shell 1 has four positioning posts 41 matched with the positioning holes 42 on the first part 23, the second part 24 has six positioning holes 42, the first shell 1 has six positioning posts 41 matched with the positioning holes 42 on the second part 24, the third part 25 has four positioning holes 42, and the first shell 1 has four positioning posts 41 matched with the positioning holes 42 on the third part 25.

[0068] In one embodiment, see 9, the at least two parts into which the substrate 2 is divided include an adjacent first part 23 and a second part 24. The elastic structure 26 includes a first elastic strip 261, which is arranged on the first part 23 of the two adjacent parts. The first elastic strip 261 and the second side 22 meet the parallel condition, and the middle part of the first elastic strip 261 is connected to the second part 24 of the two adjacent parts. The angle between the first elastic strip 261 and the second side 22 does not exceed the first threshold, and the first elastic strip 261 and the second side 22 meet the parallel condition. The first threshold can be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, etc. When the first part 23 and the second part 24 are respectively positioned with the second shell 5 through the positioning structure 4, and the elastic structure 26 is required to compensate for the tolerance, since the middle part of the first elastic strip 261 is connected to the second part 24, the first elastic strip 261 bends, thereby compensating for the accumulated tolerance between the first part 23 and the second part 24.

[0069] In one embodiment, see Fig.10 , the at least two parts into which the substrate 2 is divided include an adjacent first part 23 and a second part 24. The elastic structure 26 includes a second elastic strip 262, which is disposed on the second part 24 of the two adjacent parts, the second elastic strip 262 and the second side 22 meet the parallel condition, and the middle part of the second elastic strip 262 is connected to the first part 23 of the two adjacent parts. The angle between the second elastic strip 262 and the second side 22 does not exceed the second threshold, and the second elastic strip 262 and the second side 22 meet the parallel condition. The second threshold can be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, etc. When the first part 23 and the second part 24 are positioned with the second shell 5 respectively through the positioning structure 4, and the elastic structure 26 is required to compensate for the tolerance, since the middle part of the second elastic strip 262 is connected to the first part 23, the second elastic strip 262 bends, thereby compensating for the accumulated tolerance between the first part 23 and the second part 24.

[0070] In one embodiment, see Fig.11 The elastic structure 26 includes a first elastic strip 261 and a second elastic strip 262. The first elastic strip 261 is connected to the first part 23 of the two adjacent parts, and the second elastic strip 262 is connected to the second part of the two adjacent parts. The first elastic strip 261 and the second elastic strip 262 respectively meet the parallel condition with the second side 22. The first elastic strip 261 and the second elastic strip 262 correspond to each other one by one, and the middle part of the first elastic strip 261 is connected to the middle part of the corresponding second elastic strip 262. The parallel condition satisfied by the first elastic strip 261 or the second elastic strip 262 and the second side 22 can be specifically referred to the description of the above embodiment. The first elastic strip 261 and the second elastic strip 262 are arranged relative to each other, which can increase the deformation of the elastic structure 26 and make more compensation for the tolerance.

[0071] In one embodiment, see Fig.12 The elastic structure 26 includes at least two third elastic strips 263, the third elastic strips 263 and the second side 22 meet the parallel condition, and at least two third elastic strips 263 are connected in sequence to form a reciprocating circuitous structure, and the reciprocating circuitous structure can be extended or contracted along the first side 21, and the two ends of the reciprocating circuitous structure are respectively connected to the first part 23 and the second part 24 of the two adjacent parts. The reciprocating circuitous structure formed by the connection of the third elastic strips 263 can be extended or contracted along the first side 21, so as to compensate for the tolerance of the positioning structure 4 between the substrate 2 and the first shell 1, reduce the tolerance required for the positioning structure 4, and improve the offset of the key assembly 3.

[0072] Two adjacent third elastic strips 263 may be connected by a circuitous portion 264, so that at least two third elastic strips 263 are connected end to end in sequence to form a reciprocating circuitous structure. The angle between the third elastic strip 263 and the second side 22 does not exceed a third threshold, and the third elastic strip 263 and the second side 22 meet a parallel condition. The third threshold may be, for example, 1°, 3°, 5°, 8°, 10°, 15°, 20°, 30°, 45°, etc. The angles between different reciprocating portions and the second side 22 may be different.

[0073] The shape of the detour portion 264 may be an arc or a broken line.

[0074] In one embodiment, see Figures 8 to 12 , the substrate 2 is divided into at least two parts along the first side 21 direction by the hollow structure, and an elastic structure 26 is formed. In the embodiment of the present disclosure, a hollow structure can be formed on the substrate 2 by engraving or other processes on the basis of an integral body, and the hollow structure divides the substrate 2 into at least two parts along the first direction, and an elastic structure 26 is formed between the two adjacent parts.

[0075] In an exemplary embodiment, a first elastic strip 261 is formed by a carved hollow structure on one side of the first part 23, a second elastic strip 262 opposite to the first elastic strip 261 is formed by a carved hollow structure on one side of the second part 24, and a connecting portion is formed in the middle of the first elastic strip 261 and the second elastic strip 262.

[0076] Alternatively, the third elastic strip 263 is formed between the first portion 23 and the second portion 24 by means of a carved hollow structure.

[0077] In one embodiment, see Figure 8The substrate 2 has a key installation position 28, each key installation position 28 is connected to a group of key components 3, and the elastic structure 26 is arranged between two key installation positions 28 adjacent to each other in the direction of the first side 21. The substrate 2 is divided into at least two parts by a gap 27 formed by a hollow structure. The elastic structure 26 separates the gap 27 into a discontinuous structure. The key installation position 28 may be provided with a connecting structure, and the connecting structure is used to connect the key component 3 with the substrate 2.

[0078] In one embodiment, the substrate 2 may also be divided into at least two parts along the second side 22, and the at least two parts are connected by an elastic structure 26. By being divided into at least two parts along the first side 21 and the second side 22, the substrate 2 may be divided into smaller sizes in both the length and width directions to reduce the required tolerance.
