[0035] The following specific embodiments illustrate the implementation of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Although the description of the present application will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this application are limited to the implementation. On the contrary, the purpose of introducing the application in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present application. In order to provide a deep understanding of the present application, the following description will include many specific details. The present application can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present application, some specific details will be omitted in the description. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0038] Arcade keyboards, also known as fighting game keyboards, may cause the arcade keys on the arcade keyboard to not respond normally as time goes by. For example, the arcade keyboard may be physically damaged due to accidental falling, causing the arcade keys to malfunction, or the PCB adapter board inside the arcade keyboard may have poor contact due to dust, oxidation, etc., causing the arcade keys to fail; or, if the user presses the arcade keys too hard for a long time, the mechanical axis in the arcade keys will be damaged.

[0039] Therefore, as the arcade buttons are used for a longer time, the arcade button components, mechanical switches, and PCB adapters need to be disassembled and replaced; in addition, some users like to change the keycaps to the colors they want, and change different mechanical switches to experience different pressing forces. Due to the personalized needs of users, keycaps and mechanical switches are easy to disassemble, which can enhance the user experience. The traditional arcade button structure is not easy to replace, which affects the user experience.

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041] Figure 1 The schematic diagram of the installation of the arcade key assembly and the arcade keyboard is shown. Figure 2 A schematic diagram showing the connection between the arcade button assembly and the arcade keyboard is shown.

[0042] like Figure 1 As shown, the arcade key assembly 1 is pressed toward the key hole, and the arcade key assembly 1 can be installed in the key hole of the arcade keyboard 2. One key hole corresponds to one arcade key assembly 1, and multiple arcade key assemblies 1 can be set in the arcade keyboard 2 according to actual needs, and this embodiment does not limit this. Figure 2 As shown, after pressing, the installation of the arcade button assembly 1 is completed. At this time, the button base 30 is installed and fixed on the arcade keyboard 2, and the button pressing signal of the arcade button assembly 1 is transmitted to the arcade keyboard 2. In this embodiment, the arcade button assembly 1 is a hot-swappable button. When the arcade keyboard 2 is powered on, it will not affect the installation and removal of the arcade button assembly 1, which is convenient and practical.

[0043] Figure 3 shows a front view of the arcade button assembly, Figure 4 A perspective view of an arcade key assembly is shown, Figure 5 An exploded view of the arcade button assembly is shown. Figure 6 An exploded view showing another perspective of the arcade button assembly.

[0044] like Figure 3-6As shown, an arcade key assembly 1 provided in this embodiment includes a key base 30, a mechanical axis 20, a key cap 10 and a PCB adapter plate 40. The key base 30 is installed in the key hole to facilitate the overall installation and fixing of the arcade key assembly 1 on the arcade keyboard 2. For example, the key base 30 can be cylindrical.

[0045] refer to Figure 3 In one embodiment, a side portion of the button base 30 is provided with an elastic buckle 301; the button base 30 is assembled on the button hole through the elastic buckle 301. When the arcade button assembly 1 needs to be disassembled, the user presses the elastic buckle 301 to cause it to elastically deform inward, and then the arcade button assembly 1 can be taken out.

[0046] Figure 7 A schematic diagram of a key base is shown, Figure 8 A perspective view of a key base is shown.

[0047] See also Figure 7 , 8 A positioning hole 302 is provided inside the button base 30; the mechanical axis 20 is arranged in the button base 30 through the positioning hole 302; illustratively, a plurality of limiting protrusions 201 are provided in the middle of the side wall of the mechanical axis 20, and the positioning hole 302 is a square through hole; when the bottom of the mechanical axis 20 is accommodated in the through hole, the limiting protrusion 201 can limit the downward movement of the mechanical axis 20.

[0048] See also Figure 5 , 6 The key cap 10 is detachably connected to the mechanical shaft 20; at least one groove 101 is provided on the lower side of the key cap 10, and the groove 101 is used to separate the key cap 10 from the mechanical shaft 20 under the action of an external force;

[0049] In one embodiment, see Figure 5 , 6 The top of the mechanical switch 20 has a telescopic portion 202 ; the bottom of the keycap 10 is provided with a connecting hole 102 that matches the telescopic portion 202 .

[0050] The connection hole 102 on the keycap 10 is connected with the telescopic part 202. When the user presses on the force-bearing surface of the keycap 10, the keycap 10 moves downward, and drives the telescopic part 202 to move downward, triggering a key pressing signal. At this time, the key pressing signal of the arcade key assembly 1 is transmitted to the arcade keyboard 2. After the user's hand is away from the force-bearing surface of the keycap 10, the telescopic part 202 will rebound, and the keycap 10 will move to the initial position. It should be noted that the mechanical axis 20 used in this solution is a prior art, and the principle of the mechanical axis 20 will not be described in detail here.

[0051] For example, the cross section of the connecting hole 102 is a "cross" structure. The connecting hole 102 of the "cross" structure can enable the mechanical shaft 20 to be plugged into the keycap 10, and compared with the round hole, the keycap 10 will not move circumferentially, which is convenient for user operation.

[0052] like Figure 6 As shown in FIG. 1 , in one embodiment, a ring-shaped limiting protrusion 303 is disposed on the top of the key base 30, and the limiting protrusion 303 is used to fix the key base 30 in the axial direction. The limiting protrusion 303 can limit the downward movement of the key base 30. After the key base 30 is installed in the arcade keyboard 2, the position is as shown in FIG. Figure 2 As shown, the elastic buckle 301 will limit the upward movement of the button base 30. Therefore, the limiting protrusion 303 and the elastic buckle 301 cooperate with each other to fix the arcade button assembly 1 and the arcade keyboard 2.

[0053] In one embodiment, the horizontal plane where the top of the limiting protrusion 303 is located is higher than the horizontal plane where the top of the groove 101 is located. The key cap 10 and the key base 30 are clearance-matched.

[0054] Due to personalized needs, some users will replace the keycap 10 with the color they want. In this embodiment, in order to facilitate the replacement of the keycap 10, a groove 101 is provided on the lower side of the keycap 10. The groove 101 is used to separate the keycap 10 from the mechanical axis 20 under the action of external force. In this embodiment, if the depth of the groove 101 is set too deep, the PCB adapter board 40 inside the arcade keyboard 2 is prone to poor contact due to dust, oxidation and other reasons during use of the arcade keyboard 2, thereby affecting the service life of the arcade key assembly 1. Therefore, the horizontal plane where the top of the limiting protrusion 303 is located is higher than the horizontal plane where the top of the groove 101 is located, so that dust and moisture are not easy to enter the interior of the arcade key assembly 1. In addition, due to the position of the groove 101, the keycap 10 and the key base 30 are in clearance, so that the user can easily use external force, such as using a fingernail to open the keycap 10, which is convenient for the disassembly of the various components of the arcade key assembly 1.

[0055] Fig. 9 A perspective view of a PCB adapter plate is shown.

[0056] The PCB adapter board 40 in this embodiment is provided with an insertion interface 401 , and the PCB adapter board 40 is plugged into the bottom of the mechanical shaft 20 via the insertion interface 401 .

[0057] like Figure 5 As shown, the bottom of the mechanical switch 20 is provided with a plug-in portion 204, and the plug-in portion 204 cooperates with the plug-in port 401 to connect the PCB adapter plate 40 to the mechanical switch 20. In this embodiment, after disassembling the keycap 10 and the mechanical switch 20 in turn, the user can easily replace the PCB adapter plate 40.

[0058] refer to Figure 5 The mechanical axis 20 in this embodiment has a metal pin 203; a thermal socket 402 is provided on the PCB adapter board 40; the metal pin 203 cooperates with the thermal socket 402 to transmit the button pressing signal of the mechanical axis 20 to the PCB adapter board 40.

[0059] When installing the mechanical axis 20 , it is only necessary to align the metal pin 203 of the mechanical axis 20 with the thermal socket 402 for installation. At the same time, the plug-in portion 204 is plugged into the plug interface 401 to complete the assembly of the mechanical axis 20 and the PCB adapter board 40 .

[0060] In an optional embodiment, the PCB adapter plate 40 is connected to the key base 30 via a fastener 405. The PCB adapter plate 40 is plugged into the bottom of the mechanical axis 20 via the plug interface 401. However, in fighting games, users often press the arcade key assembly 1 vigorously. If there is no fastener 405 to connect the PCB adapter plate 40 and the key base 30, the PCB adapter plate 40 may fall off when the user uses the arcade keyboard 2, affecting the user experience. Exemplarily, the fastener 405 can be, but is not limited to, a screw.

[0061] See also Fig. 9 The PCB adapter board 40 includes a signal line pin 403 ; the signal line pin 403 is welded on the PCB adapter board 40 , and the signal line pin 403 is used to transmit the key pressing signal of the arcade key assembly 1 to the arcade keyboard 2 .

[0062] In this embodiment, the principle of triggering a key pressing signal is: after the user presses the keycap 10, since the keycap 10 is connected to the mechanical axis 20, the mechanical axis 20 is driven to move downward, and the key pressing signal of the metal pin 203 is transmitted to the signal line pin 403, and the signal line pin 403 then transmits the key pressing signal to the arcade keyboard 2.

[0063] See also Figure 8 In one embodiment, a relief hole 304 is provided at the bottom of the key base 30; the signal line pin 403 is soldered on the PCB adapter board 40 to form a solder convex portion 404; the solder convex portion 404 cooperates with the relief hole 304. After the relief hole 304 is provided, the solder convex portion 404 is accommodated in the key base 30, so that the arcade key assembly 1 can fit more closely to the bottom of the key base 30, making the connection between the PCB adapter board 40 and the key base 30 and / or the mechanical switch 20 more stable.

[0064] In order to facilitate understanding of this implementation, the following is a further explanation in combination with the working principle:

[0065] When disassembling the arcade button assembly 1, a connecting hole 102 is provided at the bottom of the keycap 10 to cooperate with the telescopic part 202 of the mechanical axis 20. The keycap 10 and the mechanical axis 20 are plugged in through the cooperation of the connecting hole 102 and the telescopic part 202. Therefore, the user applies external force to the groove 101 on the lower side of the keycap 10 to separate the telescopic part 202 from the connecting hole 102, so that the keycap 10 is separated from the mechanical axis 20, which meets the user's personalized needs of replacing the keycap 10 with different colors; after the keycap 10 is disassembled, since the bottom of the mechanical axis 20 is accommodated in the positioning port 302 of the button base 30, the user can directly remove the mechanical axis 20, in order to allow the user to experience different pressing forces, or to press the arcade button too hard for a long time, which may cause the mechanical axis 20 in the arcade button to be damaged, and the purpose of replacing the mechanical axis 20.

[0066] When removing the mechanical axis 20, the plug-in part 204 of the mechanical axis 20 is separated from the plug-in interface 401 of the PCB adapter board 40, and the metal pin 203 of the mechanical axis 20 is also separated from the thermal socket 402 on the PCB adapter board 40. When the PCB adapter board 40 has poor contact due to dust, oxidation, etc., the user can easily disassemble the PCB adapter board 40.

[0067] When installing the arcade key assembly 1, first, the bottom of the mechanical axis 20 is accommodated in the positioning hole 302 of the key base 30, and the plug-in portion 204 of the mechanical axis 20 is aligned with the plug-in port 401 of the PCB adapter board 40, and the metal pin 203 of the mechanical axis 20 is aligned with the hot socket 402 on the PCB adapter board 40; after the PCB adapter board 40 and the mechanical axis 20 are installed, the PCB adapter board 40 and the key base 30 can be further firmly installed by the fastener 405; then, the connecting hole 102 of the keycap 10 is plugged with the telescopic portion 202 of the mechanical axis 20; finally, the key base 30 is installed facing the key hole, at which time the key base 30 is assembled on the key hole by the elastic buckle 301, and the limiting protrusion 303 set on the top of the key base 30 limits the downward movement of the key base 30, so that the arcade key assembly 1 is firmly installed in the key hole of the arcade keyboard 2.

[0068] The structure of the arcade button provided in the embodiment of the present application is easy to disassemble and replace as a whole and each component thereof, which is convenient and practical.

[0069] This embodiment further provides an arcade keyboard 2 , which includes a plurality of arcade key assemblies 1 . The arcade key assemblies 1 are installed in key holes of the arcade keyboard 2 .

[0070] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
