[0056] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0057] Figure 1 The schematic diagram of the structure of the host 10 provided in this embodiment is as follows: Figure 2 is a schematic cross-sectional structure diagram of a key structure 100 provided in this embodiment, Figure 3 This is a schematic structural diagram of the integrated mechanical key board 110 provided in this embodiment at a first viewing angle, Figure 4 This is a schematic cross-sectional view of the integrated mechanical key board 110 provided in this embodiment. Figure 1-Figure 4 This embodiment provides an integrated mechanical key board 110, and accordingly, provides a key structure 100 and a host 10.

[0058] The host 10 includes a key structure 100, and the host 10 also includes a front shell 22 and a main shell 21. The main shell 21 has a front opening and a top opening. The integrated mechanical key plate 110 of the key structure 100 is arranged at the top opening of the main shell 21, serving as the top plate of the shell of the host 10 to close the top opening. The front shell 22 is arranged at the front opening of the main shell 21 to close the front opening, thereby forming a closed accommodating cavity. Further, the host 10 also includes an electronic device (not shown), which is arranged in the accommodating cavity.

[0059] The key structure 100 includes an integrated mechanical key plate 110 and a button 151 . The button 151 is operated by pressing a key portion 123 of the integrated mechanical key plate 110 .

[0060] The integrated mechanical key board 110 has a top surface 111 and a bottom surface 112 that are opposite to each other. The top surface 111 is provided with a first groove 113, so that a housing portion 122 and a key portion 123 are separated on both sides of the first groove 113. After installation and use, the housing portion 122 is used as a part of the housing. The bottom surface 112 of the key portion 123 is provided with a second groove 114, and a first elastic arm 116 is formed between the second groove 114 and the first groove 113, so as to realize the elastic connection between the housing portion 122 and the key portion 123. Since the housing portion 122 and the key portion 123 are an integrated structure formed by the groove, it helps to avoid the formation of a height difference between the housing portion 122 and the key portion 123, and the appearance is more beautiful.

[0061] The integrated mechanical key board 110 provided in this embodiment is further described below:

[0062] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the integrated mechanical key board 110 is a rectangular plate-shaped member as a whole, and the top surface 111 and the bottom surface 112 of the integrated mechanical key board 110 are the walls on both sides of the thickness direction of the integrated mechanical key board 110. The first groove 113 extends along the length direction of the integrated mechanical key board 110, so that the button part 123 and the shell part 122 formed on both sides of the first groove 113 are distributed along the width direction of the integrated mechanical key board 110, and the size of the button part 123 in the width direction of the integrated mechanical key board 110 is smaller than the size of the shell part 122 in the width direction of the integrated mechanical key board 110. The second groove 114 is provided on the back side of the button part 123, and the back side of the button part 123, that is, the back side of the integrated mechanical key board 110 corresponds to the button part 123.

[0063] Furthermore, a third groove 115 is formed on the bottom surface 112 of the housing portion 122, a second elastic arm 117 is formed between the third groove 115 and the first groove 113, and the second groove 114 and the third groove 115 are respectively located on both sides of the first groove 113. The third groove 115 is formed on the back side of the housing portion 122, and the back side of the housing portion 122, i.e., the back side of the integrated mechanical key board 110, corresponds to the part of the housing portion 122.

[0064] Specifically, the first groove 113, the second groove 114 and the third groove 115 are all U-shaped grooves. The first elastic arm 116 is formed between the first groove 113 and the second groove 114, which can also be understood as the first groove 113 and the second groove 114 are separated by the first elastic arm 116; the second elastic arm 117 is formed between the third groove 115 and the first groove 113, which can also be understood as the first groove 113 and the third groove 115 are separated by the second elastic arm 117. At the same time, the first elastic arm 116 and the second elastic arm 117 both extend along the thickness direction of the integrated mechanical key plate 110, that is, the first elastic arm 116 and the second elastic arm 117 are arranged in parallel. A connecting arm 118 is formed between the bottom wall of the first groove 113 and the bottom surface 112 of the integrated mechanical key plate 110, and the two ends of the connecting arm 118 are respectively connected to the first elastic arm 116 and the second elastic arm 117. In other words, the first elastic arm 116, the connecting arm 118 and the second elastic arm 117 are sequentially connected to define the first groove 113.

[0065] Furthermore, the thickness of the housing portion 122 is greater than the thickness of the button portion 123, and the top surface 111 of the housing portion 122 is flush with the top surface 111 of the button portion 123, so that the bottom surface 112 of the housing portion 122 is protruded relative to the bottom surface 112 of the button portion 123. The bottom surface 112 at the connecting arm 118 is flush with the bottom surface 112 of the button portion 123.

[0066] In the present embodiment, the integrated mechanical key plate 110 is a metal plate, and the first groove 113, the second groove 114 and the third groove 115 are all machined. Specifically, the integrated mechanical key plate 110 is a sheet metal part made by cutting, CNC processing, shaping and other forming processes. Optionally, the first groove 113, the second groove 114 and the third groove 115 are formed by milling. Optionally, the material of the integrated mechanical key plate 110 is aluminum alloy, specifically, the material of the integrated mechanical key plate 110 is aluminum alloy 5052. It can be understood that in other embodiments, other aluminum alloy materials or other metal materials can also be used.

[0067] Figure 5 for Figure 4 The enlarged schematic diagram of the local structure shown in Figure Ⅴ. Please refer to Figure 3-Figure 5 In this embodiment, the arm thickness of the first elastic arm 116 is C, 0.05mm≤C≤0.6mm, optionally, C=0.05mm or 0.6mm. Further, 0.35mm≤C≤0.6mm, specifically, the arm thickness of the first elastic arm 116 can be regarded as the distance between the first groove 113 and the second groove 114 in the width direction of the integrated mechanical key board 110. Optionally, C=0.35mm, 0.5mm or 0.6mm. Thus, the elastic effect of the first elastic arm 116 is ensured.

[0068] The arm thickness of the second elastic arm 117 is A, 0.05mm≤A≤0.5mm, optionally, A=0.05mm or 0.5mm. Further, 0.35mm≤A≤0.45mm. Specifically, the arm thickness of the second elastic arm 117 can be regarded as the distance between the first groove 113 and the third groove 115 in the width direction of the integrated mechanical key board 110. Optionally, A=0.35mm, 0.4mm or 0.45mm. Thus, the elastic effect of the second elastic arm 117 is ensured.

[0069] The width of the first groove 113 is B, 0.3 mm ≤ B ≤ 0.8 mm, optionally, B = 0.3 mm or 0.8 mm. Further, 0.65 mm ≤ B ≤ 0.75 mm. Specifically, the width of the first groove 113 can be regarded as the dimension of the first groove 113 in the width direction of the integrated mechanical key board 110. Optionally, B = 0.65 mm, 0.7 mm, or 0.75 mm.

[0070] The distance between the bottom wall of the second groove 114 and the top surface 111 of the button portion 123 is D, 0.05 mm ≤ D ≤ 0.7 mm, optionally, D = 0.05 mm or 0.7 mm. Further, 0.35 mm ≤ D ≤ 0.6 mm. Alternatively, D = 0.35 mm, 0.5 mm or 0.6 mm.

[0071] The arm thickness dimension of the connecting arm 118 is E, 0.15 mm ≤ E ≤ 0.5 mm, optionally, E = 0.15 mm or 0.5 mm. Further, 0.35 mm ≤ E ≤ 0.45 mm. Alternatively, E = 0.35 mm, 0.4 mm or 0.45 mm.

[0072] By setting the above dimensions, the elastic connection effect and the rebound effect between the button portion 123 and the housing portion 122 are effectively guaranteed.

[0073] Along the direction from the housing portion 122 to the button portion 123, that is, the width direction of the integrated mechanical key board 110, the size of the button portion 123 is F, 20mm≤F≤40mm. Optionally, F=20mm, 30mm or 40mm. The larger the width of the button portion 123, the smaller the pressing force. By setting the width of the button portion 123, it is helpful to ensure the elastic pressing function.

[0074] Please refer to it again Figure 3 and Figure 4In this embodiment, at least one cutting groove 124 is provided on the key portion 123, and the cutting groove extends from the edge of one end of the key portion 123 away from the housing portion 122 to the first groove 113, so that the key portion 123 is divided into at least two key monomers 125 by the at least one cutting groove 124. Specifically, the cutting groove 124 extends along the width direction of the integrated mechanical key plate 110, and in the thickness direction of the integrated mechanical key plate 110, the cutting groove 124 penetrates the top surface 111 and the bottom surface 112 of the key portion 123, so that the key portion 123 is divided into at least two key monomers 125 distributed along the length direction of the integrated mechanical key plate 110. At the same time, since the cutting groove 124 extends to the first groove 113, the connecting arm 118 formed at the bottom of the first groove 113 and the first elastic arm 116 formed between the first groove 113 and the second groove 114 are both divided into multiple parts by the cutting groove 124.

[0075] In this embodiment, the number of the cutting grooves 124 is three, and accordingly, the button portion 123 is divided into four button monomers 125. It is understandable that in other embodiments, the number of the cutting grooves 124 can also be specifically set according to the number of button monomers 125 required.

[0076] Figure 6 This is a schematic diagram of the structure of the integrated mechanical key board 110 provided in this embodiment at a second viewing angle, that is, a schematic diagram of the structure of the back side of the integrated mechanical key board 110. Figure 3-Figure 6 In this embodiment, the width dimension of the second groove 114 is d, 2mm≤d≤11mm, optionally, d=2mm or 11mm. Further, 8.2mm≤d≤10mm. Optionally, d=8.2mm, 9mm or 10mm. Specifically, the second groove 114 has a first side wall 119 and a second side wall 121 which are arranged oppositely along the direction from the shell part 122 to the button part 123, that is, the first side wall 119 and the second side wall 121 are arranged at intervals along the width direction of the integrated mechanical key board 110, and the width dimension of the second groove 114 is the distance between the first side wall 119 and the second side wall 121. Further, the dimension of the button monomer 125 in the distribution direction of at least two button monomers 125 is e, that is, e is the dimension of the button monomer 125 in the length direction of the integrated mechanical key board 110. 40mm≤e≤50mm. Optionally, e=40mm, 45mm or 50mm.

[0077] It should be noted that the structure on the back of the integrated mechanical key panel 110 is not limited here. It is understandable that in other embodiments, a bone protrusion 126 located in the second groove 114 may be provided on the edge of one end of the key unit 125 close to the adjacent key unit 125.

[0078] As an example, Figure 7 , Figure 8 and Fig. 9 FIG. 1 shows the structure of the back side of another integrated mechanical key board 110. Figure 7 As shown, a bone protrusion 126 located in the second groove 114 is provided near one end edge of the key monomer 125 adjacent to the adjacent key monomer 125, one end of the bone protrusion 126 is connected to the first side wall 119, and the other end of the bone protrusion 126 is spaced apart from the second side wall 121. Specifically, the bone protrusion 126 is a strip-shaped protrusion extending along the width direction of the integrated mechanical key board 110.

[0079] exist Figure 7 In the structure shown, the distance between the first side wall 119 and the second side wall 121 is a1, 2mm≤a1≤11mm, optionally, a1=2mm or 11mm. Further, 8.2mm≤a1≤10mm. Optionally, a1=8.2mm, 9mm or 10mm. The distance between the bone protrusion 126 and the second side wall 121 is a2, 0.5mm≤a2≤5mm, optionally, a2=0.5mm or 5mm. Further, 3.5mm≤a2≤4.5mm. Optionally, a2=3.5mm, 4mm or 4.5mm. The width of the bone protrusion 126 is a3, 0.2mm≤a3≤1.8mm, optionally, a3=0.2mm or 1.8mm. Further, 1.0mm≤a3≤1.5mm. Optionally, a3=1.0mm, 1.3mm or 1.5mm. It should be noted that the width of the bone protrusion 126 is the dimension of the bone protrusion 126 in the length direction of the integrated mechanical key plate 110 .

[0080] At the same time Figure 7 In the structure shown, the button monomer 125 located in the middle, that is, the two sides of the button monomer 125 are respectively adjacent to other button monomers 125, and only one edge is provided with a bone protrusion 126.

[0081] By setting the dimensions of the key unit 125 at various locations, the pressing force of the key is optimized.

[0082] exist Figure 8 In the structure shown, the bone position protrusion 126 is arranged with Figure 7The structures shown are roughly the same, except that bone protrusions 126 are provided at the edges of both sides of the button monomer 125 located in the middle, and the two bone protrusions 126 provided on the same button monomer 125 are respectively the first bone protrusion 127 and the second bone protrusion 128. One end of the first bone protrusion 127 is connected to the first side wall 119, and the other end of the first bone protrusion 127 is spaced apart from the second side wall 121; one end of the second bone protrusion 128 is connected to the second side wall 121, and the other end of the second bone protrusion 128 is spaced apart from the first side wall 119.
