[0026] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] like Figures 1 to 6As shown, this utility model embodiment provides a button assembly, including a button body 1 and a substrate 2. The substrate 2 is provided with a mounting hole 21 that penetrates its thickness. The side wall of the mounting hole 21 is provided with a guide groove 211 and a locking groove 212. The guide groove 211 is provided through the substrate 2 axially. The locking groove 212 is circumferentially spaced downstream of the rotation trajectory of the guide groove 211. The locking groove 212 extends axially from the bottom to the top of the substrate 2, and the depth of the locking groove 212 is less than the thickness of the substrate 2. The button body 1 is provided with flanges 112 and limiting protrusions 111 arranged vertically at intervals. During installation, the limiting protrusions 111 enter the guide groove 211 along the axial direction of the substrate 2 and then rotate circumferentially into the locking groove 212, so that the button body 1 is axially limited on the substrate 2.

[0033] On the side wall of the mounting hole 21, a guide groove 211 and a locking groove 212 are provided. The guide groove 211 and the locking groove 212 generally appear in pairs, and the pair of guide grooves 211 and locking grooves 212 are symmetrically arranged around the center of the mounting hole 21. The guide groove 211 extends through the substrate 2 axially, that is, it extends from one end of the substrate 2 to the other end. The width of the guide groove 211 is slightly larger than the width of the limiting protrusion 111. In the initial stage of installing the button body 1, the guide groove 211 provides an axial channel for the limiting protrusion 111 to enter.

[0034] The locking groove 212 is circumferentially spaced downstream of the rotation trajectory of the guide groove 211. When the limiting protrusion 111 enters along the axial direction of the guide groove 211, the limiting protrusion 111 can reach the locking groove 212 by circumferentially rotating the button body 1. The locking groove 212 extends axially from the bottom to the top of the substrate 2, and its depth is less than the thickness of the substrate 2. When the limiting protrusion 111 reaches the locking groove 212, the upper surface of the limiting protrusion 111 and the bottom of the locking groove 212 form mutual interference in the axial direction. This design ensures that the axial positioning of the button body 1 is guaranteed, and the overall strength of the substrate 2 is not affected by the excessive depth of the locking groove 212.

[0035] The button body 1 is provided with flanges 112 and limiting protrusions 111 arranged at intervals. The flanges 112 function as a stop structure. When the button body 1 is mounted on the substrate 2, the flanges 112 can abut against the upper surface of the substrate 2 to prevent the button body 1 from being over-inserted into the mounting hole 21.

[0036] The quick assembly and disassembly of the button body 1 is achieved through the cooperation between the guide groove 211 and the locking groove 212 and the limiting protrusion 111. Compared with the traditional button installation method, there is no need for complicated screw tightening operations, which greatly improves production and assembly efficiency. Moreover, after installation, since the limiting protrusion 111 is stuck in the locking groove 212, it can effectively prevent the button body 1 from axially loosening during use, ensuring the stability after installation.

[0037] In one embodiment, such as Figure 4 As shown, the guide groove 211 is provided with a guide surface 2111, and the locking groove 212 is provided with a circumferential extension surface 2121. The guide surface 2111 and the circumferential extension surface 2121 are smoothly transitioned.

[0038] The guide surface 2111 of the guide groove 211 provides an initial guide path for the axial movement of the limiting protrusion 111 during the installation of the button body 1. In practical applications, the guide surface 2111 can be designed as a smooth plane, so that when the limiting protrusion 111 of the button body 1 is inserted into the guide groove 211 along the axial direction of the substrate 2, it can slide in with minimal friction.

[0039] The circumferential extension surface 2121 of the locking groove 212 provides guidance for the circumferential rotation of the limiting protrusion 111 after it completes its axial movement. When the limiting protrusion 111 rotates into the locking groove 212, the circumferential extension surface 2121 can ensure that the limiting protrusion 111 is stably kept in a fixed position within the locking groove 212, so that the limiting protrusion 111 can fit tightly against the circumferential extension surface 2121 and prevent it from dislodging from the locking groove 212 due to shaking during use.

[0040] It should be noted that the smooth transition between the guide surface 2111 and the circumferential extension surface 2121 ensures that the limiting protrusion 111 will not encounter any obvious steps or obstacles during its rotation from the guide groove 211 to the locking groove 212.

[0041] The smooth transition between the guide surface 2111 and the circumferential extension surface 2121 greatly improves the smoothness of the button body 1 installation process. Ordinary technicians can easily rotate the limiting protrusion 111 from the guide groove 211 to the locking groove 212 when installing the button body 1, without additional force or adjustment. At the same time, this smooth transition also enhances the stability of the button assembly during use. Because the limiting protrusion 111 transitions smoothly between the guide surface 2111 and the circumferential extension surface 2121, it will not cause improper installation due to jamming during installation, thus effectively avoiding problems such as loosening or displacement of the button body 1 during use, improving the overall reliability and service life of the button assembly.

[0042] In one embodiment, such as Figure 3 and Figure 4 As shown, a locking structure is provided between the circumferential extension surface 2121 and the limiting protrusion 111. The locking structure includes a locking groove 1111 and a locking block 21211. The locking groove 1111 is provided with one of the circumferential extension surface 2121 and the limiting protrusion 111, and the locking block 21211 is provided with the other of the circumferential extension surface 2121 and the limiting protrusion 111.

[0043] Specifically, the placement of the slot 1111 and the locking block 21211 is flexible. A common implementation involves setting the slot 1111 on the circumferential extension surface 2121 and correspondingly setting the locking block 21211 on the limiting protrusion 111. The shape of the slot 1111 can be designed according to actual needs, such as a rectangular slot with a width slightly larger than the width of the locking block 21211, and the depth determined according to the material and strength requirements of the button body 1. At the corresponding position of the limiting protrusion 111, i.e., the part where the limiting protrusion 111 contacts the circumferential extension surface 2121, a rectangular locking block 21211 adapted to the slot 1111 is integrally molded by injection molding. When the button body 1 is installed in place, after the limiting protrusion 111 rotates to the locking groove 212, the locking block 21211 fits snugly into the slot 1111, forming a tight fit.

[0044] In another embodiment, a slot 1111 is provided on the limiting protrusion 111, and a block 21211 is provided on the circumferential extension surface 2121.

[0045] The locking structure significantly improves the stability of the button assembly. When the button is subjected to external force, whether it is pressed, shaken, or subjected to force in other directions, the cooperation between the locking slot 1111 and the locking block 21211 effectively prevents the button body 1 from displacing relative to the base plate 2 in the circumferential and axial directions. Compared with a design without a locking structure, the button is less likely to loosen during long-term and frequent use, greatly extending the service life of the button assembly. Moreover, this structure is simple and straightforward to design, easy to implement in the manufacturing process, and does not require complex processes or high costs.

[0046] In one embodiment, such as Figure 3 As shown, the key body 1 includes a base 11, a keycap 12, a sensor switch 13, and a silent silicone 14. The keycap 12 and the sensor switch 13 are mounted on the base 11, and the flange 112 and the limiting protrusion 111 are provided on the outer surface of the base 11.

[0047] The base 11 is a cylindrical structure with an open top. A flange 112 extends along the edge of the opening of the base 11 away from its center, forming a disc-like structure. This facilitates a tight fit with the upper surface of the substrate 2 during installation, providing axial positioning. Simultaneously, a limiting protrusion 111 is formed on the outer side of the base 11. The limiting protrusion 111 can be designed as a rectangular block, with its diameter and height adapted to the dimensions of the guide groove 211 and the locking groove 212, ensuring smooth engagement with the corresponding structure on the substrate 2 during installation.

[0048] Keycap 12 is mounted on base 11 and is primarily used for user operation. Keycap 12 and base 11 are connected via a snap-fit ​​mechanism; specifically, base 11 has a snap-fit ​​notch 114, and keycap 12 has a corresponding snap-fit ​​clip 121 that engages with the snap-fit ​​notch 114. During keycap 12 injection molding, the snap-fit ​​clip 121 is integrally formed on its bottom edge, while the snap-fit ​​notch 114 is provided at the corresponding position on base 11. During installation, aligning the snap-fit ​​clip 121 on keycap 12 with the snap-fit ​​clip 114 on base 11 and gently pressing achieves a tight connection. This connection method is convenient and quick, facilitating replacement of keycap 12 in case of damage.

[0049] It should be noted that the button travel can be adjusted by setting different heights of the bayonet 114.

[0050] The inductive switch 13 is a key component for realizing the button function. The inductive switch 13 is a common standard part on the market and is not the focus of this application, so it will not be described in detail here.

[0051] To achieve a silent button effect, a silent silicone 14 is fitted onto the inductive switch 13.

[0052] In one embodiment, such as Figure 3 As shown, the outer surface of the base 11 is also provided with a pressing part 113 that presses against the side wall of the mounting hole 21.

[0053] The extrusion section 113 can take various forms depending on the actual situation. A common form is to provide an annular extrusion rib on the outer surface of the base 11. Taking a common circular button base 11 as an example, during injection molding, an annular extrusion rib is integrally formed on the outer surface of the base 11 near the edge and at a position that matches the mounting hole 21 using a mold. The height and width of the annular extrusion rib are designed according to requirements to ensure that when the button body 1 is installed into the mounting hole 21 of the substrate 2, the annular extrusion rib can be tightly extruded and fitted with the side wall of the mounting hole 21.

[0054] Another implementation involves providing multiple strip-shaped extrusion portions 113 evenly distributed circumferentially along the outer surface of the base 11. The length of these strip-shaped extrusion portions 113 can be adjusted according to the side length of the base 11, and the width and height must also be adapted to the size of the mounting hole 21. During installation, these strip-shaped extrusion portions 113 contact the sidewall of the mounting hole 21 and generate an extrusion effect, which not only enhances the stability of the button body 1 on the substrate 2, but also disperses the external force on the button to a certain extent, preventing damage due to excessive local stress.

[0055] In one embodiment, the upper surface of the flange 112 is provided with a disassembly tool insertion hole 1121. For example... Figure 3 As shown, there are two disassembly tool insertion holes 1121, which are symmetrically arranged with respect to the center of the base 11.

[0056] The disassembly tool insertion hole 1121 provided on the upper surface of the flange 112 is to facilitate the disassembly of the button body 1. Specifically, the flange 112, as a structure on the button body 1 used to cooperate with the substrate 2 and restrict axial movement, greatly facilitates subsequent maintenance and replacement operations by providing the disassembly tool insertion hole 1121 on its surface.

[0057] On the upper surface of flange 112, disassembly tool insertion holes 1121 are provided by mechanical drilling or by pre-reserving holes during injection molding. Since two disassembly tool insertion holes 1121 are provided and they are symmetrical with respect to the center of base 11, the diameter of the disassembly tool insertion holes 1121 must ensure that common disassembly tools 100, such as small pry bars or dedicated button disassembly tools 100, can be inserted smoothly, without affecting the structural strength of flange 112 due to excessively large hole diameter.

[0058] like Figure 5 and Figure 6 As shown, when the button body 1 needs to be disassembled for repair or replacement, the repair personnel can insert the insertion parts 200 at both ends of the disassembly tool 100 into the two symmetrically arranged disassembly tool insertion holes 1121 respectively. Due to the symmetrical arrangement, when an external force is applied to pry the button body 1, it can ensure uniform force distribution and avoid damage to the button body 1 or the base plate 2 due to uneven force distribution.

[0059] The inclusion of a disassembly tool insertion hole 1121 significantly reduces the difficulty of disassembling the button body 1, improving maintenance and replacement efficiency. Furthermore, placing the disassembly tool insertion hole 1121 on the flange 112 does not affect the normal operation of the button and ensures its aesthetic appearance.

[0060] This utility model embodiment also provides a game controller, including the above-described button components.

[0061] Apart from the aforementioned button components, the rest of the game controller's structure is identical to that in the prior art, and will not be described in detail here. Since the game controller uses the aforementioned button components, it possesses all the beneficial effects of those components, and will not be elaborated upon further.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
