At the same time, the positioning column 61 cooperating with the positioning hole 62 also ensures the accurate positioning of the first key 1, the second key 2 and the third key 3 and the physical keys 51 on the circuit board 5, improving the user's experience.

[0055] As shown in Figure 7 , Figure 9 and Figure 11 , the first positioning block 11 is provided with a positioning hole 62 at the left end of the front face of the first key 1, the second positioning block 21 is provided with a positioning hole 62 at both ends of the front face of the second key 2, and the third positioning block 31 is provided with a positioning hole 62 at the left end of the front face of the third key 3, and the back face of the front shell 4 is provided with a positioning column 61 matched with the positioning hole 62 at the upper and lower sides of the let-through hole 41.

[0056] In the embodiment, the positioning holes 62 are arranged on the first positioning block 11, the second positioning block 21 and the third positioning block 31, and the positioning columns 61 are arranged on the back of the front shell 4, but are not limited thereto, and in other embodiments, the positioning holes 62 can also be arranged on the back of the front shell 4, and the positioning columns 61 can be arranged on the first positioning block 11, the second positioning block 21 and the third positioning block 31. Since the first button 1, the second button 2 and the third button 3 need to be overlapped with each other through the first positioning block 11, the second positioning block 21 and the third positioning block 31, the first positioning block 11 is provided with a positioning hole 62 at the left end of the front face of the first button 1, the second positioning block 21 is provided with positioning holes 62 at both left and right ends of the front face of the second button 2, the third positioning block 31 is provided with a positioning hole 62 at the left end of the front face of the third button 3, and the number of the positioning columns 61 on the back of the front shell 4 matches the number of the positioning holes 62. Of course, in other embodiments, the arrangement positions of the positioning holes 62 and the positioning columns 61 can be adjusted according to actual needs.

[0057] As shown in Figure 7 , Figure 8 and Figure 12 , the first positioning block 11 is provided with a first stepped surface 111 at the right end of the front face of the first button 1, the first stepped surface 111 is provided with a connecting hole 72, the third positioning block 31 is provided with a second stepped surface 311 at the left end of the back of the third button 3, the second stepped surface 311 is provided with a connecting column 71 matched with the connecting hole 72, and the third positioning block 31 is overlapped in the connecting hole 72 of the first stepped surface 111 of the first positioning block 11 through the connecting column 71 of the second stepped surface 311.

[0058] In the embodiment, the stepped surfaces are arranged on the first positioning block 11 and the third positioning block 31, so that the vertical heights of the first button 1 and the third button 3 after being overlapped with each other are flush, thereby ensuring the feeling of button pressing. The overlapped mode of the connecting column 71 matched with the connecting hole 72 makes the assembly of the buttons more convenient and improves the installation efficiency. Of course, in other embodiments, the arrangement positions of the connecting column 71 and the connecting hole 72 can be adjusted according to actual needs.

[0059] As shown in Figures 9 to 11 , the third positioning block 31 is provided with a third stepped surface 312 at the right end of the front face of the third button 3, the third stepped surface 312 is provided with a connecting hole 72, the second positioning block 21 is provided with a fourth stepped surface 211 at the left end of the back of the second button 2, the fourth stepped surface 211 is provided with a connecting column 71 matched with the connecting hole 72, and the second positioning block 21 is overlapped in the connecting hole 72 of the third stepped surface 312 of the third positioning block 31 through the connecting column 71 of the fourth stepped surface 211.

[0060] The embodiment sets a stepped surface on the second positioning block 21 and the third positioning block 31, so that the vertical height of the second button 2 and the third button 3 after overlapping each other is flush, ensuring the feeling of button pressing. Through the overlapping mode of the connecting column 71 cooperating with the connecting hole 72, the assembly between the buttons is more convenient, and the installation efficiency is improved.

[0062] The elastic arm 81 of the embodiment can provide stable support for the button, ensuring that the button maintains the correct position when it is not pressed. At the same time, when the button is pressed, the elastic arm 81 can automatically reset the button by using its elastic restoring force, ensuring the continuity and accuracy of the button operation. In addition, the pressing feeling of the button can also be optimized through the elastic arm 81, improving the user's experience, and the structure is simple, and the elastic arm 81 and the positioning block are integrally formed, which is beneficial to production and also improves the service life.

Through the limiting column 9, the pressing stroke of the button can be limited, preventing the physical button 51 of the circuit board 5 from being damaged due to excessive pressing of the button, which helps to protect the integrity and functionality of the entire button structure.

[0066] As shown in Figure 8 , Figure 10 and Figure 12As shown, the number of the limiting posts 9 is four, and the limiting posts 9 are respectively arranged at four corners of the back of the first button 1, the second button 2 and the third button 3, so that the stress generated when the buttons are pressed can be shared, and the stability of the button pressing can be improved.

[0067] The embodiment also provides an electronic device applying the cascade full-motion button structure, and specifically, the front shell 4 of the cascade full-motion button structure is the front shell of the electronic device.

[0068] The two third buttons 3 are overlapped with each other to form a button group through the connecting columns 71 of the third positioning blocks 31 and the connecting holes 72, the third button 3 on the left side of the button group is overlapped on the connecting column 71 of the right end of the first positioning block 11 of the first button 1 through the connecting hole 72 of the left end of the third positioning block 31, and the connecting hole 72 of the left end of the second positioning block 21 of the second button 2 is overlapped on the connecting column 71 of the third positioning block 31 of the third button 3 on the right side of the button group, so that the first positioning block 11, the third positioning block 31 and the second positioning block 21 on the upper and lower sides of the first button 1, the two third buttons 3 and the second button 2 are overlapped to form a row, and the longitudinal heights are flush.

[0069] Then, the four buttons overlapped to form the row are installed on the corresponding positioning columns 61 on the upper and lower sides of the accommodation through hole 41 on the back of the front shell 4 through the positioning holes 62 on the front of the buttons, as shown in Figure 5 Finally, the circuit board 5 is locked on the back of the front shell 4, and the installation is completed.
