[0035] The keyboard is an instruction and data input device for operating electronic equipment. Letters, numbers and punctuation marks can be input into electronic equipment through the keyboard to issue commands to electronic equipment. In order to improve the reliability of the keyboard, the circuit board inside the keyboard needs to be sealed. In the related art, a sealing groove is mainly provided on the shell of the keyboard, and a sealing ring is filled in the sealing groove to improve the sealing performance; that is, the sealing groove is used to seal the connection between the top shell and the bottom shell of the shell. However, the above scheme needs to be filled with a sealing cavity during assembly, so that the assembly process of the keyboard is increased, which leads to a relatively complicated assembly procedure, thereby affecting the production efficiency.

[0036] Based on the above considerations, in order to solve the problem of complicated sealing design assembly process in the related art, a keyboard is designed. The bottom shell is provided with a bottom shell back plate and a bottom shell frame surrounding the outer edge of the bottom shell back plate, and the inner side surface of the bottom shell frame is provided with a support part. During assembly, only the cover plate needs to be covered on the open end of the frame and adhered to the connecting surface of the support part to complete the assembly and form a sealing cavity for accommodating the circuit board, thereby effectively improving the assembly efficiency of the keyboard.

[0037] In the following, the keyboard provided by the embodiment of the present application will be further described.

[0038] Please refer to Figures 1 to 4In a first aspect, the embodiments of the present application provide a keyboard 1000, comprising a bottom shell 100, a cover plate 200, a circuit board 300 and a key assembly 400; the bottom shell 100 comprises a bottom shell back plate 110 and a bottom shell frame 120 surrounding the outer edge of the bottom shell back plate 110, the inner side surface of the bottom shell frame 120 is provided with a support part 130, the support part 130 has a connecting surface 131 facing away from the bottom shell back plate 110; the cover plate 200 covers the open end of the bottom shell frame 120, the cover plate 200 is sealingly bonded to the connecting surface 131, the cover plate 200, the bottom shell frame 120 and the bottom shell back plate 110 together enclose a sealed cavity 101, and the circuit board 300 is accommodated in the sealed cavity 101; the key assembly 400 is covered on the cover plate 200 and connected to the bottom shell back plate 110 and / or the bottom shell frame 120; the key assembly 400 is connected to the circuit board 300 through wireless induction.

[0039] The bottom shell 100 comprises the bottom shell back plate 110 and the bottom shell frame 120 surrounding the outer edge of the bottom shell back plate 110, so that the bottom shell frame 120 and the bottom shell back plate 110 can together enclose a cavity structure to facilitate the accommodation and assembly of other components.

[0040] The inner side surface of the bottom shell frame 120 refers to the side surface of the bottom shell frame 120 facing the enclosed interior. The inner side surface of the bottom shell frame 120 is provided with a support part 130; wherein the support part 130 can be a protruding block structure protruding from the surface of the bottom shell frame 120; the support part 130 can be integrally formed with the bottom shell frame 120.

[0041] The bottom shell back plate 110 can be of any shape, for example, but not limited to, a rectangular back plate, an arc-shaped back plate, a circular back plate or a special-shaped back plate, etc. The outer shape of the bottom shell frame 120 is consistent with the outer shape of the bottom shell back plate 110, so that the bottom shell frame 120 can surround the outer edge of the bottom shell back plate 110.

[0042] Alternatively, the number of support parts 130 can be multiple, and the multiple support parts 130 are sequentially distributed on the inner side surface of the bottom shell frame 120; the multiple support parts 130 are used together to support and connect the cover plate 200. Alternatively, the number of support parts 130 can be one, i.e. the inner side surface of the bottom shell frame 120 can form a continuous annular protruding structure; in this way, the annular support part 130 is used to support the cover plate 200 and sealingly bond the cover plate 200 to the connecting surface 131 to form a better sealing effect.

[0043] The cover plate 200 is sealed and attached to the connecting surface 131 of the frame 120, so that the cover plate 200 can be attached to the connecting surface 131 of the support 130 and form a seal, so that the cover plate 200, the frame 120 and the back plate 110 together form a sealed cavity 101, and the circuit board 300 contained in the sealed cavity 101 has better sealing effect.

[0044] It should be understood that the open end of the frame 120 refers to the end of the frame 120 facing away from the back plate 110. The cover plate 200 can be made of injection molding material, glass material, etc. For example, the cover plate 200 can be made of organic glass plate. The cover plate 200 can have a configuration similar to that of the back plate, so that when the cover plate 200 is sealed to the open end of the frame, the gap between the cover plate 200 and the frame is smaller, thereby further improving the sealing performance of the sealed cavity 101.

[0045] The circuit board 300 is an infrastructure for supporting and connecting electronic components. It is usually composed of a non-conductive substrate material (such as paper composite board, epoxy glass cloth substrate, etc.) covered with conductive paths (usually copper foil). The circuit board 300 is contained in the sealed cavity 101. Optionally, the circuit board 300 can be fixedly installed in the sealed cavity 101 by screws or other fasteners, for example, fixed on the back plate 110, or a limiting structure can be provided on the back plate 110 for limiting the assembly of the circuit board 300.

[0046] The key assembly 400 is connected to the circuit board 300 by wireless induction. During use, the user can input electrical signals by pressing the key assembly 400. The wireless induction includes but is not limited to electric induction, magnetic induction, optical induction, etc.

[0047] The keyboard 1000 provided by the embodiment of the application sets the bottom shell 100 to include the back plate 110 and the frame 120 surrounding the outer edge of the back plate 110, and the inner side surface of the frame 120 is provided with the support 130. During assembly, only the cover plate 200 needs to be sealed to the open end of the frame and attached to the connecting surface 131 of the support 130 to complete the assembly and form the sealed cavity 101 for containing the circuit board 300, thereby effectively improving the assembly efficiency of the keyboard 1000.

[0048] Please refer to Figures 1 to 4 In some embodiments, the support 130 is annularly arranged on the inner side surface of the frame 120 and forms a ring.

[0049] In the embodiment, the support portion 130 is protruded on the inner side surface of the bottom shell frame 120 and forms a protruding portion structure in a ring shape; in this way, when the cover plate 200 is capped on the opening end of the bottom shell frame 120, the edges of the side of the cover plate 200 towards the support portion 130 can be connected with the connecting surface 131 of the support portion 130.

[0050] In this way, the connecting surface 131 of the support portion 130 in a ring shape and the cover plate 200 form a ring-shaped sealing protection through bonding, which can effectively improve the sealing performance inside; at the same time, during assembly, the cover plate 200 and the connecting surface 131 only need to be directly bonded and assembled, which can reduce the step of filling the sealing ring compared with the scheme of setting the sealing ring, thereby effectively improving the assembly efficiency of the keyboard 1000.

[0051] Please refer to Figures 1 to 4 In some embodiments, the cover plate 200 is bonded to the connecting surface 131 through a dispensing structure.

[0052] In the embodiment, the dispensing structure can be used to bond and fix the cover plate 200 and the connecting surface 131. Alternatively, the dispensing structure can refer to a structure with strong adhesion formed by a small amount of adhesive. For example, the dispensing structure can be a round dot structure, a strip structure, etc. The number of dispensing structures can be multiple, and multiple dispensing structures are arranged on the connecting surface 131.

[0053] In this way, the dispensing structure is used to bond and fix the cover plate 200 and the connecting surface 131, and multiple dispensing structures can be arranged at intervals, thereby effectively reducing the material of the dispensing structure and further reducing the total cost.

[0054] Please refer to Figures 1 to 4 In some embodiments, in the height direction of the bottom shell frame 120, the connecting surface 131 and the side end surface of the bottom shell frame 120 away from the bottom shell back plate 110 have a height difference; the connecting surface 131 and the inner side surface of the bottom shell frame 120 together form a containing groove 102, and at least part of the cover plate 200 is contained in the containing groove 102.

[0055] In the height direction of the bottom shell frame 120, the connecting surface 131 and the side end surface of the bottom shell frame 120 away from the bottom shell back plate 110 have a height difference, and the support portion 130 is formed on the inner side surface of the bottom shell frame 120; in this way, the connecting surface 131 of the support portion 130 and part of the inner side surface of the bottom shell frame 120 can together form a containing groove 102.

[0056] When the cover plate 200 is capped on the opening end of the bottom shell frame 120, the cover plate 200 abuts against and is sealedly bonded to the connecting surface 131 of the support portion 130. In this way, at least part of the cover plate 200 can be accommodated in the accommodating groove 102. Exemplarily, in some embodiments, the cover plate 200 can be partially protruded outside the accommodating groove 102; or, the cover plate 200 can also be completely accommodated in the accommodating groove 102, for example, the surface of the cover plate 200 is flush with the side end surface of the bottom shell frame 120 facing outward.

[0057] In this way, the assembly compactness between the cover plate 200 and the bottom shell 100 can be improved, at least part of the cover plate 200 is accommodated in the area enclosed by the bottom shell frame 120, so as to reduce the overall volume of the keyboard 1000.

[0058] Please refer to Figures 1 to 4 In some embodiments, the cover plate 200 is flush with the side end surface of the bottom shell frame 120 facing away from the bottom shell back plate 110.

[0059] In this embodiment, the cover plate 200 is arranged to be flush with the side end surface of the bottom shell frame 120 facing away from the bottom shell back plate 110; that is, when the cover plate 200 is capped on the opening end of the bottom shell frame 120 and is sealedly bonded to the connecting surface 131, the side surface of the cover plate 200 facing away from the bottom shell back plate 110 is flush with the side end surface of the bottom shell frame 120 facing away from the bottom shell back plate 110. In this way, after the cover plate 200 and the bottom shell 100 are sealedly assembled, the cover plate 200 will not protrude outward from the bottom shell 100 in the height direction of the bottom shell frame 120.

[0060] Exemplarily, in some embodiments, the distance between the connecting surface 131 and the side end surface of the bottom shell frame 120 facing away from the bottom shell back plate 110 can be greater than or equal to 0.5 mm and less than or equal to 2 mm, for example, specifically can be 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, 1.2 mm, 1.5 mm, 1.7 mm, 1.9 mm, etc. It should be understood that the distance between the connecting surface and the side end surface of the bottom shell frame 120 facing away from the bottom shell back plate 110 can be selected according to the specific thickness of the cover plate 200.

[0061] In this way, after the cover plate 200 is assembled on the bottom shell 100, the cover plate 200 can form an integral body with the bottom shell 100, and the cover plate 200 will not protrude outward from the bottom shell frame 120, so as to effectively improve the assembly compactness of the cover plate 200 and the bottom shell 100, and further improve the compactness of the keyboard 1000.

[0062] Please refer to Figures 1 to 5In some embodiments, the bottom shell frame 120 is provided with a mounting hole 121, which is communicated with the sealing cavity 101; a waterproof and dustproof connector female seat 500 is sealingly arranged in the mounting hole 121, and the waterproof and dustproof connector female seat 500 is electrically connected to the circuit board 300.

[0063] The mounting hole 121 is used for plug-in connection of the waterproof and dustproof connector female seat 500. Optionally, the number of the mounting hole 121 can be one, two or more; the number of the waterproof and dustproof connector female seat 500 matches the number of the mounting hole 121, so that each mounting hole 121 is respectively plug-in connected with the waterproof and dustproof connector female seat 500.

[0064] The mounting hole 121 is communicated with the sealing cavity 101, so that the waterproof and dustproof connector female seat 500 can be electrically connected to the circuit board 300 in the sealing cavity 101 to realize assembly.

[0065] The waterproof and dustproof connector female seat 500 refers to a connector female seat with certain waterproof and dustproof performance; optionally, the waterproof and dustproof connector female seat 500 includes but is not limited to a USB female seat, a type-c female seat and the like. In the embodiment, the waterproof and dustproof connector female seat 500 can select a common IP68 waterproof and dustproof USB connector female seat; in this way, the waterproof and dustproof performance of the keyboard 1000 during wired connection can be improved.

[0066] Please refer to Figures 1 to 5 In some embodiments, the circuit board 300 is provided with a connection slot 310, which is located on the side of the circuit board 300 facing the bottom shell back plate 110, and the waterproof and dustproof connector female seat 500 is plug-in arranged in the connection slot 310 through a wire.

[0067] In the embodiment, the connection slot 310 is arranged on the side of the circuit board 300 facing the bottom shell back plate 110, so as to reduce the influence of the connection slot 310 on the connection between the circuit board 300 and the key assembly 400.

[0068] The waterproof and dustproof connector female seat 500 is plug-in arranged in the connection slot 310 through a wire, so as to realize electrical connection between the waterproof and dustproof connector female seat 500 and the circuit board 300.

[0069] Please refer to Figures 1 to 4 In some embodiments, the key assembly 400 includes an upper cover 410 and a key structure 420 arranged on the upper cover 410, the upper cover 410 is arranged on the cover plate 200 and is connected to the bottom shell back plate 110 and / or the bottom shell frame 120; the key structure 420 is provided with a first sensing structure (not shown in the figure), and the circuit board 300 is provided with a second sensing structure 320 corresponding to the first sensing structure, the first sensing structure and the second sensing structure 320 are connected through wireless sensing.

[0070] The upper cover 410 is used to cover the cover plate 200 and connect the back plate 110 and / or the frame 120 of the bottom shell, so that the key assembly 400 is assembled on the bottom shell 100 and forms the keyboard 1000. The upper cover 410 can be, but is not limited to, a flat plate structure, a groove structure with one end open, and the like.

[0071] The upper cover 410 can be connected to the back plate 110 of the bottom shell. For example, in some embodiments, the upper cover 410 can cover the frame 120 of the bottom shell, and the upper cover 410 extends to the back plate 110 of the bottom shell and is fixedly connected to the back plate 110 of the bottom shell in various connection modes such as snap connection, fastener connection, and the like.

[0072] The upper cover 410 can also be connected to the frame 120 of the bottom shell.
