[0027] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0028] The tactile button assembly device includes a button shell 1, a fixed button shell 2, multiple elastic seats 3, and multiple button caps 4. Each button cap is assembled and electrically connected to a control board 5. The button shell 1 is used to receive pressing pressure. The button shell 1 and the fixed button shell 2 are assembled together. Each elastic seat 3 and each button cap 4 are arranged in a one-to-one correspondence. Along the top-to-bottom direction, the fixed button shell 2, the elastic seat 3, and the button cap 4 are arranged in a sequential abutting assembly. The elastic seat 3 is deformed under pressing pressure and is used to transmit pressing pressure to the button cap 4.

[0029] In the aforementioned tactile button assembly device, when the user operates the button, the button shell 1 receives the pressing force, transmits it to the fixed button shell 2, and then transmits the pressing force to each button cap 4 through each elastic seat 3, realizing the input of the control command. With the cooperation of the button shell 1 and the fixed button shell 2, the stability of the button's swing under force is better. At the same time, the elastic seat 3 deforms under the pressing force, making the pressing operation more flexible and comfortable. Furthermore, the elastic seat 3 can provide feedback of the force, enhancing the user's pressing tactile sensation and improving the user's pressing operation experience, thereby improving the user's control experience.

[0030] In addition, the button shell 1 and the fixed key shell 2 are assembled by snapping together. The button shell 1 receives the pressing pressure and transmits it to the fixed key shell 2. The pressing is more flexible and does not feel particularly stiff. This enhances the user's pressing feel and improves the user's pressing operation experience, thereby improving the user's control experience.

[0031] The key housing 2 includes a key housing plate 21 and a key housing post 22. The lower end of the key housing post 22 is fixedly arranged with the control plate 5, and the upper end of the key housing post 22 is connected to the key housing plate 21. The key housing plate 21 is suspended. Under the action of the key housing post 22, the key housing plate 21 is set and is pressed and oscillated, which facilitates the oscillation of the key and realizes the input and reset of the command.

[0032] The button housing 1 and the fixed housing plate 21 are assembled together, and each elastic seat 3 is installed on the fixed housing plate 21; under the action of the fixed housing plate 21, the assembly of each elastic seat 3 is realized.

[0033] The fixed shell plate 21 has a lower plate surface facing the button cap 4, and each elastic seat 3 is installed at intervals on the lower plate surface to achieve a flush assembly of each elastic seat 3.

[0034] Each elastic seat 3 is arranged in a uniform manner, and together with the lower plate, the fixed shell plate 21 is arranged horizontally, which facilitates the input of different commands.

[0035] The elastic seat 3 is arranged in a frustum shape, and its cross-sectional area gradually decreases along the direction away from the lower plate. This facilitates the transmission of pressing pressure from the elastic seat 3 to the key cap 4, improving the accuracy of command input. At the same time, it facilitates the reset of the elastic seat 3 and increases the area of ​​the elastic seat 3 that receives pressing pressure.

[0036] The key shell 1 includes a middle shell post 11. The upper part of the middle shell post 11 is fixedly arranged, and the lower part of the middle shell post 11 extends toward the fixed key shell 2. The middle shell post 11 extends through the fixed shell plate 21 and is embedded in the interior of the fixed shell post 22. In this way, the assembly stability between the key shell 1 and the fixed key shell 2 is improved by the action of the middle shell post 11.

[0037] The fixed shell plate 21 has an upper plate surface facing away from the button cap 4. The upper plate surface has a horizontal plate groove 212 and a vertical plate groove 213.

The horizontal shell plate 12 is fixedly arranged with the horizontal plate groove 212, and the vertical shell plate 13 is fixedly arranged with the vertical plate groove 213.

[0038] The cooperation between the horizontal shell plate 12 and the horizontal plate groove 212, and the cooperation between the vertical shell plate 13 and the vertical plate groove 213, plays a role in positioning and restricting the key shell 1 and the fixed key shell 2, thereby improving the assembly stability between the key shell 1 and the fixed key shell 2 and ensuring the transmission of pressing force.

[0039] The button housing 1 includes a horizontal housing and a vertical housing, which are arranged in a cross shape. The horizontal housing plate 12 is located inside the horizontal housing, and the vertical housing plate 13 is located inside the vertical housing.

[0040] The fixed shell plate 21 includes four fixed plate strips 211. The inner ends of the four fixed plate strips 211 are joined together and integrally formed. The outer ends of the four fixed plate strips 211 extend outward and are arranged in a cross shape. The fixed plate strips 211 are embedded with a horizontal shell or a vertical shell. The elastic seat 3 is installed at the outer end of the fixed plate strips 211.

[0041] The four fixed strips 211, in conjunction with the horizontal or vertical shell, improve the assembly stability of the key shell 1 and the fixed key shell 2.

[0042] The two ends of the horizontal shell plate 12 are respectively formed with horizontal abutment portions 14. The horizontal abutment portions 14 are arranged to protrude in the direction toward the fixed plate strip 211.

The vertical abutment portions 15 are arranged to protrude in the direction toward the fixed plate strip 211. The vertical abutment portions 15 and the elastic seat 3 are arranged correspondingly. The vertical abutment portions 15 are embedded with vertical plate grooves 213.

[0043] The cooperation between the horizontal stop 14 and the horizontal plate groove 212, and the cooperation between the vertical stop 15 and the vertical plate groove 213, improves the assembly stability of the key shell 1 and the fixed key shell 2.

[0044] The horizontal abutment 14 includes two horizontal abutment pieces arranged in a cross-shaped pattern. A horizontal hole 214 is formed at the end of the horizontal plate groove 212. The horizontal hole 214 is arranged in a cylindrical shape. The outer extensions of the two horizontal abutment pieces respectively abut against the hole wall of the horizontal hole 214. The vertical abutment 15 includes two vertical abutment pieces arranged in a cross-shaped pattern. A vertical hole 215 is formed at the end of the vertical plate groove 213. The vertical hole 215 is arranged in a cylindrical shape. The outer extensions of the two vertical abutment pieces respectively abut against the hole wall of the vertical hole 215. This improves the assembly stability of the key shell 1 and the fixed key shell 2.

[0045] The outer end of the fixed plate strip 211 forms a strip fixing part 216, which is arranged in an arched arc shape facing outward; the transverse shell has a transverse fixing groove 16, which is arranged in an arched arc shape along the direction towards the end; the longitudinal shell has a longitudinal fixing groove, which is arranged in an arched arc shape along the direction towards the end; the strip fixing part 216 is embedded with the transverse fixing groove 16 or the longitudinal fixing groove.

[0046] The locking part 216, in cooperation with the horizontal locking groove 16 or the vertical locking groove, serves as a limiting part, preventing misalignment between the key shell 1 and the key shell 2, ensuring the assembly effect of the key shell 1 and the key shell 2, and facilitating the application of pressing pressure.

[0047] The button housing 1 includes multiple connecting plates 17. The two ends of the connecting plates 17 are respectively arranged to meet the adjacent horizontal and vertical housings, and the connecting plates are arranged in an arc shape facing outwards. The tactile button assembly device includes a housing 7. The button housing 1 is movably embedded in the housing 7. The housing 7 includes multiple machine plates 6. The machine plates 6 are arranged in an arc shape. Each machine plate 6 is arranged in a one-to-one correspondence with each connecting plate 17, and the machine plate 6 and the connecting plate 17 are arranged to overlap and abut against each other.

[0048] In this way, the coordinated action of each circuit board 6 and each connecting plate 17 plays a positioning and guiding role in the movement of the button shell 1, preventing the button shell 1 from shifting under the action of pressing pressure, and facilitating the reset of the button shell 1.

[0049] The connecting plate, horizontal shell, and vertical shell are arranged in an integral molding configuration, which facilitates production and manufacturing. At the same time, the bottom surfaces of the connecting plate, the horizontal shell, and the vertical shell are arranged flush, without any unevenness, thus avoiding affecting the internal space layout of the casing 7 and reducing restrictions on the installation of other components.
