[0052] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0053] Please see Figure 1 and Figure 5 One embodiment of this application provides a frame structure 100, which can be applied to various handheld electronic devices 200 (such as smartphones, tablets, etc.), remote controls, game controllers, and industrial control equipment with button operation functions, as well as other devices that require button interaction.

[0054] The frame structure 100 includes a movable button 10, a frame 20, and a colloid 30. The frame 20 has an opening 21. The movable button 10 is movably disposed in the opening 21. A groove 211 is formed in the recessed sidewall of the opening 21, and the groove 211 communicates with the opening 21. The colloid 30 is accommodated in the groove 211.

[0055] When in use, when an external force is applied to the active button 10, the active button 10 moves accordingly within the opening 21 of the frame 20. During this process, the colloid 30 within the slot 211 can stabilize the movement trajectory of the active button 10 and provide cushioning and shock absorption. At the same time, due to the design of the slot 211, the distribution range of the colloid 30 can be effectively controlled, reducing uncontrolled glue overflow during button operation. Thus, not only is the normal and stable operation of the frame structure 100 guaranteed, but the reliability and durability of the frame structure 100 are also greatly improved, reducing button malfunctions or assembly problems caused by glue overflow or uneven distribution of colloid 30, thereby improving the overall product quality and user experience.

[0056] Please see Figure 3 and Figure 4In some possible embodiments, the frame 20 includes a first connecting portion 22 and a second connecting portion 23 connecting the first connecting portion 22. A connecting line S is provided between the first connecting portion 22 and the second connecting portion 23, with one end of the connecting line S exposed at the bottom of the slot 211. An opening 21 penetrates through the first connecting portion 22 and the second connecting portion 23. The first connecting portion 22 is made of titanium alloy, and the second connecting portion 23 is made of aluminum alloy. Thus, during the use of the frame structure 100, when the colloid 30 is injected into the groove 211, some of the colloid 30 can penetrate and fill along the bonding line S to a certain extent. On the one hand, this can further enhance the stability of the connection between the first bonding part 22 and the second bonding part 23, preventing loosening or separation due to long-term use or external impact. On the other hand, the filling of the colloid 30 in the bonding line S can effectively isolate the corrosion of the titanium alloy and aluminum alloy joint by external environmental factors, especially against possible moisture, dust, etc., greatly improving the corrosion resistance of the joint, extending the overall service life of the frame structure 100, and ensuring that the button can work stably and reliably in various complex environments. In other embodiments, the material of the first bonding part 22 can be stainless steel, engineering plastic, carbon fiber composite material, etc., and the material of the second bonding part 23 can be zinc alloy, magnesium alloy, ceramic, etc.

[0057] In some possible embodiments, the first joint 22 has a first side surface 221. The second joint 23 has a second side surface 231. The first side surface 221 and the second side surface 231 are arranged parallel and spaced apart to form a joint line S. The extension direction of the first side surface 221 or the second side surface 231 is defined as the length direction A. Along the length direction A, the depth D of the groove 211 is 0.3~0.5 mm, and along the perpendicular length direction A, the cross-sectional width W1 of the groove 211 is 0.8~0.9 mm. Thus, this specific groove 211 size design can provide more sufficient and suitable accommodating space for the adhesive 30 while ensuring the structural strength and stability of the frame 20, which is beneficial for accommodating more adhesive 30 and preventing it from overflowing.

[0058] In some possible implementations, the first bonding portion 22 further includes a third side surface 222 and a first connecting surface 223. The third side surface 222 is disposed opposite to the first side surface 221. The first connecting surface 223 is disposed between the first side surface 221 and the third side surface 222. The first connecting surface 223 is connected to the first side surface 221 through the wall of the slot 211. The first thickness direction B is defined as the distance from the first side surface 221 to the third side surface 222. Along the thickness direction B, the distance W2 between the bonding line S and the third side surface 222 is 1.0~1.5 mm. This distance W2 is beneficial to keep the bonding line S away from the third side surface 222. In this way, the colloid 30 can more easily cover the bonding line S while further reducing the risk of the colloid 30 overflowing to the third side surface 222.

[0059] In some possible embodiments, the second connecting portion 23 includes a body portion 232, a stepped portion 233, and an enclosing portion 234. The stepped portion 233 connects the body portion 232 and the enclosing portion 234. The body portion 232 includes a second side surface 231, and the stepped portion 233 includes a second connecting surface 233a and an extending surface 233b, the extending surface 233b being perpendicularly connected to the second connecting surface 233a. The second connecting surface 233a is connected to the second side surface 231 through the wall of the slot 211. The enclosing portion 234 connects to the extending surface 233b, the extending surface 233b being used to accommodate a portion of the colloid 30 overflowing from the slot 211, and a partial opening 21 penetrating the enclosing portion 234. Thus, when the colloid 30 is filled into the slot 211, even if a small amount of colloid 30 overflows, the extension surface 233b can effectively receive and accommodate the overflowing colloid 30, reducing the further spread of the colloid 30 to other critical parts of the frame structure 100, thereby preventing functional failures such as button jamming and short circuits caused by overflowing colloid, as well as corrosion and damage to surrounding components.

[0060] In some possible implementations, the frame structure 100 further includes a seal 40, which is fitted onto the active button 10, with the side of the seal 40 away from the active button 10 abutting against the inner wall of the opening 21. The seal 40 is made of an elastic material such as silicone or rubber. Thus, the seal 40 can create a good seal between the active button 10 and the inner wall of the opening 21, effectively preventing external dust, moisture, and other impurities from entering the frame structure 100, thereby reducing problems such as button malfunction and corrosion caused by impurity accumulation, and ensuring the normal operation and service life of the frame structure 100. Simultaneously, due to its elastic material properties, the seal 40 can act as a buffer during the pressing of the active button 10, reducing noise and wear caused by friction and collision between the active button 10 and the inner wall of the opening 21, further improving the comfort and quietness of button operation.

[0061] In some possible implementations, the active button 10 includes a keycap 11 and two limiting posts 12 connecting the keycap 11. The limiting posts 12 are movably perforated by an opening 21, and a sealing member 40 is fitted onto the limiting posts 12. The opening 21 includes a first portion 212 and two second portions 213 communicating with the first portion 212. The first portion 212 is exposed on a third side surface 222, and the second portions 213 penetrate the enclosure portion 234. The cross-sectional width of the first portion 212 is greater than the cross-sectional width of the second portion 213. The keycap 11 is movably accommodated in the first portion 212, and the limiting posts 12 are movably accommodated in the second portions 213. Thus, the larger cross-sectional width of the keycap 11 provides a more spacious pressing area, facilitating user operation and effectively distributing pressing force. The relatively narrow second portions 213, in conjunction with the limiting posts 12, precisely limit the range and direction of movement of the active button 10, preventing excessive offset or wobbling during pressing, and ensuring the accuracy and stability of the button's action. The sealing element 40 on the limiting post 12 further enhances the sealing and cushioning between the limiting post 12 and the second part 213, reducing problems such as abnormal noise, wear and dust ingress that may be caused by friction and the joint line S.

[0062] In some possible implementations, the first connecting surface 223 and the second connecting surface 233a are flush. The keycap 11 includes a top surface 111, a bottom surface 112, an end surface 113, and a side surface 114. The end surface 113 is connected to the side surface 114, and the end surface 113 is slidably disposed on the first connecting surface 223 and the second connecting surface 233a. The top surface 111 and the bottom surface 112 are spaced apart. The end of the end surface 113 away from the side surface 114 is connected to the top surface 111, and the side of the side surface 114 away from the end surface 113 is connected to the bottom surface 112. The side surface 114 is obliquely connected to the end surface 113 and the bottom surface 112. The side surface 114 is disposed corresponding to the stepped portion 233. The bottom surface 112 is disposed corresponding to the first portion 212. Thus, when the keycap 11 is pressed, the end face 113 can slide smoothly along the flush first connecting surface 223 and second connecting surface 233a, ensuring the smoothness and straightness of the keycap 11 pressing action and reducing the occurrence of jamming or deviation. The inclined side contact surface 114 corresponds to the stepped portion 233, which helps to reduce the compression of the portion of the colloid 30 that overflows onto the extension surface 233b, thereby maintaining the original shape and distribution of the colloid 30 on the extension surface 233b and preventing potential problems caused by excessive deformation or extrusion of the colloid 30 from the extension surface 233b due to the pressing of the keycap 11.

[0063] Please see Figure 5According to another aspect of this application, an electronic device 200 is provided, including the aforementioned frame structure 100. Specifically, the electronic device 200 includes basic components such as a housing, a display screen, a motherboard, and corresponding functional modules. These components work together to realize the various functions of the electronic device 200. The frame structure 100 can serve as the power button, volume button, etc., of portable electronic devices such as smartphones and tablets, and can also be used as the operation button of a smartwatch, the function button of a game controller, or the control button of a smart speaker, etc., for corresponding function control parts of various electronic devices 200. By adopting the frame structure 100 provided in this application, the electronic device 200 can obtain a more stable, reliable, and comfortable user experience in terms of button operation, reducing the button malfunctions and poor assembly caused by problems such as excess glue in traditional frame structures 100, effectively improving the overall quality and durability of the electronic device 200.
