[0041] It is understandable that, referring to Figure 7 It is a four-way integrated key that adopts the conventional keycap skirt structure 400 design. When the blind spot of the four-way key is pressed, the symmetrical position centered on the central fulcrum cannot move upward freely, which can easily lead to poor key pressing.

[0042] Reference Figures 1 to 6 The combined structure key of the first aspect of the present application is applied to the field of boards, and particularly relates to the switching application of hand-drawn boards in different working modes. It mainly solves the problems of the multi-directional integrated keys of hand-drawn boards being easily blocked by dead keys and the linkage of adjacent keys. The combined structure key includes a shell 100, a circuit board assembly 200 and a key component 300.

[0043] The shell 100 is formed with a key via 110; the circuit board assembly 200 is arranged on the shell 100, and the circuit board assembly 200 includes a plurality of key switches 210, and the position of the key switch 210 corresponds to the position of the key via 110; the key component 300 is arranged on the shell 100 and located at the key via 110, and the key component 300 includes a first key component 310 and a second key component 320, the first key component 310 is made of a flexible material, and the second key component 320 is made of a hard material, and the second key component 320 is arranged on the first key component 310 and combined into a whole, so that the second key component 320 can drive the first key component 310 to move and trigger the key switch 210 when pressed.

[0044] Reference Figures 1 to 6The combined structure key of the first aspect of the present application is combined into an integrated key by combining a first key component 310 made of a flexible material and a second key component 320 made of a hard material. The material properties of the flexible material are utilized to enable the key to cooperate normally with the key switch 210. At the same time, the material properties of the hard material can also ensure sufficient assembly strength of the key structure, thereby eliminating the design of the skirt structure 400, avoiding problems such as dead keys, loose noises, and key linkage without function due to insufficient thickness and space.

[0045] In some embodiments of the present application, the first button assembly 310 includes a four-way key, and the second button assembly 320 is configured as a structure compatible with the first button assembly 310. It can be understood that the four-way key is divided into buttons for the four directions of up, down, left, and right, and the second button assembly 320 is adapted to the first button assembly 310 so that the buttons for the four directions of up, down, left, and right are all soft-hard combination buttons. In some embodiments, the flexible material is soft glue and the hard material is hard glue, which is easy to manufacture and saves costs. In other embodiments, the flexible material and the hard material can be selected from conventional materials suitable for making buttons, which will not be described in detail.

[0046] In some embodiments, the first button component 310 includes a soft-glue plus key and a minus key, and the second button component 320 is configured to have a structure compatible with the first button component 310 including a hard-glue plus key and a minus key.

[0047] In some embodiments of the present application, the first button assembly 310 includes a first panel 311, a central portion 312 and four flexible buttons 313, the central portion 312 is arranged on the first panel 311, and each flexible button 313 is arranged in a circular array around the central portion 312, the second button assembly 320 includes a second panel 321, a support portion 322 and four hard keycaps 323, the support portion 322 is arranged on the second panel 321, and each hard keycap 323 is arranged in a circular array around the support portion 322, the support portion 322 is suitable for being arranged on the central portion 312, so that the second panel 321 is arranged on the first panel 311, and each hard keycap 323 cooperates with each flexible button 313 respectively, so that each flexible button 313 is suitable for triggering each button switch 210 respectively.

[0048] It is understandable that the central fulcrum can solve the problem of the symmetrical key linkage of the fulcrum center to a certain extent. The side skirt-free structure 400 is designed so that when the four-way key is pressed, the support portion 322 and the center portion 312 can be used as the central fulcrum to move freely, wherein the support portion 322 can be a support bone, the center portion 312 can be a support column with a mounting hole, the support portion 322 is arranged in the mounting hole, and the first panel 311 is attached to the second panel 321 so that the hard keycap 323 can move freely and drive the flexible key 313. In some embodiments, the first panel 311, the center portion 312 and the four flexible keys 313 are an integrated structure, all made of flexible materials. Similarly, the second panel 321, the support portion 322 and the four hard keycaps 323 are an integrated structure, all made of hard materials. After the hard glue and the soft glue are combined, there is a buffering effect during the pressing process to reduce the key sound.

[0049] In some embodiments of the present application, a skirt stop 314 is provided on the outer side of the first panel 311, and the skirt stop 314 is suitable for sealing against the housing 100; it can be understood that the skirt anti-static stop of the rubber key, the housing 100 and the circuit board assembly 200 are designed without gaps, forming a relatively closed loop area, which can prevent static electricity from passing through the key via 110, thereby improving the probability of passing the ESD test. In some embodiments, the circuit board is a PCB motherboard.

[0050] In some embodiments of the present application, an elastic arm 315 is provided on the bottom surface of the first panel 311, and the elastic arm 315 acts on the flexible button 313 so that the flexible button 313 has a tendency to reset upward; it can be understood that the elastic arm 315 is used to reset the flexible button 313, so that the flexible button 313 can be used normally for multiple times. In some embodiments, since the first panel 311 is made of a flexible material, the elastic arm 315 and the first panel 311 are an integrated structure, and the material properties can be used to reset the flexible button 313. In other embodiments, the elastic arm 315 can be set as a spring or other structural member that can reset the flexible case.

[0051] In some embodiments of the present application, a four-key partition wall 324 is provided on the second panel 321, and the four-key partition wall 324 separates four key areas, and each hard keycap 323 is respectively arranged in each key area; it can be understood that the four-key partition wall 324 preliminarily separates the hard keycap 323, which can play a certain degree of anti-dead key and adjacent key linkage effect. In some embodiments, the four-key partition wall 324 and the second panel 321 are an integrated structure, and the support portion 322 is arranged at the center of the four-key partition wall 324.

[0052] In some embodiments of the present application, at least one foolproof structure 330 is provided on the first button assembly 310 and / or the second button assembly 320. It is understandable that by providing one or more foolproof structures 330, the first button assembly 310 and the second button assembly 320 can be correctly assembled. In some embodiments, the foolproof structure 330 includes but is not limited to a foolproof groove and a foolproof positioning bone, etc. The foolproof groove and the foolproof positioning bone are limited to have a specific orientation such as horizontal and vertical, size and width, etc., so as to achieve a foolproof effect. Specifically, one or more foolproof structures 330 can be provided on at least one of the first button assembly 310 and the second button assembly 320.

[0053] In some embodiments of the present application, a key blind spot 325 is provided on the surface of the hard keycap 323, a contact column 326 is provided at a position corresponding to the key blind spot 325 in the bottom surface of the hard keycap 323, a contact blind hole 316 is provided at a position corresponding to the contact column 326 in the surface of the flexible key 313, the contact column 326 is arranged on the contact blind hole 316, and a key contact 317 is provided at a position corresponding to the contact blind hole 316 in the bottom surface of the flexible key 313, and the key contact 317 can trigger the key switch 210. It can be understood that the key blind spot 325 is convenient for guiding the user to press, and the key blind spot 325, the contact column 326, the contact blind hole 316 and the key contact 317 are arranged in sequence in the same vertical direction, so that after pressing the hard keycap 323, the flexible key 313 can be smoothly driven to move and the case switch can be smoothly triggered, ensuring the smoothness of the pressing process. In some embodiments, the key blind spot 325 is disposed in the middle of the surface of the hard keycap 323 , thereby ensuring that the hard keycap 323 is subjected to stable force.

[0054] In some embodiments of the present application, an anti-linking fulcrum 318 is provided between adjacent flexible keys 313, and each hard keycap 323 is respectively arranged on the flexible key 313 with each anti-linking fulcrum 318 as a movable base. It can be understood that the anti-linking fulcrum 318 is used to improve the problem of linking of adjacent keys when pressing in four directions. In some embodiments, the anti-linking fulcrum 318 and the first panel 311 are an integrated structure, and the soft rubber fulcrum has a compressive elasticity, which can improve the phenomenon of easy key jamming caused by other hard fulcrum methods.

[0055] In some embodiments of the present application, the bottom surface of the hard keycap 323 is provided with a glue support bone 327, and the surface of the flexible key 313 is provided with a glue overflow groove 319, and the hard keycap 323 is bonded to the flexible key 313 by setting the glue on the glue support bone 327 and the glue overflow groove 319. It can be understood that the hard keycap and the soft glue key need to be glued together to form a whole, that is, a soft and hard glue integrated key. The design of the glue support bone 327 can ensure a better bonding effect of the glue, and the glue overflow groove 319 can accommodate excess glue to avoid affecting the connection effect and the key.

[0056] In some embodiments, the adhesive support bone 327 is configured as a grid-like structure, the contact column 326 is disposed on the adhesive support bone 327, and the glue overflow groove 319 is evenly arranged based on the contact blind hole 316.

It can be understood that the support frame 120 is used to limit and position the key component 300 so that it can move smoothly, and the corresponding support frame 120 is arranged according to the corresponding structure of the four-way key, the plus key, and the minus key. In some embodiments, the support frame 120 and the housing 100 are an integrated structure, and the support frame 120 is arranged around the key through hole 110.

[0058] In some embodiments of the present application, positioning columns 130 and screw columns 140 are arranged at intervals on the supporting frame 120. The positioning columns 130 are suitable for positioning the button component 300, and the screw columns 140 are suitable for allowing threaded fasteners to pass through to relatively fix the circuit board assembly 200, the button component 300 and the housing 100. It can be understood that the circuit board assembly 200 is designed with positioning holes, screw holes and key switches 210. The circuit board assembly 200 and the housing 100 and the soft and hard rubber integrated key are fixed to each other by fixing screws. During assembly, the soft and hard rubber combination structure button is installed from the inside of the housing 100 to the outside, and the anti-mistake groove and positioning hole of the button are installed into the corresponding column, and then the positioning hole of the circuit board assembly 200 is installed into the positioning column 130 of the housing 100, and finally the fixing screw is passed through the circuit board assembly 200 through the hole to lock the screw and fix it.

[0059] Reference Figures 1 to 6The electronic product of the second aspect of the embodiment of the present application can be a hand-painted electronic product such as a hand-painted board. The electronic product includes the combined structure key of the first aspect of the embodiment of the present application, and the built-in soft glue and hard glue combined structure key installed from the inside of the machine shell 100. The problems of dead keys without function or loose and abnormal sounds caused by pressing the keys during production and assembly and the key linkage without function are greatly improved. The key is divided into two parts: a hard glue key cap and a soft glue multi-key integrated key. The hard key cap adopts a design that cancels the skirt structure 400. The two are bonded into this integrated key by a specific glue. The integrated key is installed in the shell 100 from the inside to the outside, and the circuit board assembly 200 is covered on the key, and then the circuit board assembly 200, the key and the shell 100 are fixed together by fixing screws. The built-in soft and hard glue combination structure key of the present application avoids the shortcoming of the conventional pure hard glue key that is inelastic, thereby achieving the purpose of greatly improving the dead key without function or loose and abnormal sound and key linkage without function caused by factors such as the floating height tolerance of the key switch 210 patch on the mainboard, the production assembly tolerance and the manufacturing tolerance of components.
