The button assembly controls the switch to control the mechanical component to trigger the electrical connection assembly, thereby realizing the control of the switch.

[0003] In existing technologies, such as Figure 7 As shown, the inner bracket 200 is installed in the middle of the middle cover 100. The inner bracket 200 is provided with a fulcrum for supporting the button assembly 300. Outer edge fulcrums are provided on both sides of the middle cover to support the edge buttons that the inner bracket 200 cannot support. However, when the panel assembly is installed to the bottom box, the force points of the mounting screws are located on both sides of the middle cover, causing the sides of the middle cover to deform and the outer edge fulcrums to shift. This results in poor support for the edge buttons and may even render the edge buttons unusable. Summary of the Invention

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0035] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0036] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0037] like Figures 1 to 5 As shown, the button support structure according to an embodiment of the present invention includes a middle cover 100 and an inner bracket 200. Mounting portions 110 are respectively provided on the left and right sides of the middle cover 100. The inner bracket 200 is used to mount a switch control assembly 400. The inner bracket 200 is mounted in the middle of the middle cover 100 and located between the two mounting portions 110. The inner bracket 200 is provided with a central fulcrum 120 for supporting the button assembly 300. The inner bracket 200 is provided with an extension frame 210 extending to the outside of the two mounting portions 110. The extension frame 210 is separable from the mounting portion 110, and the extension frame 210 is provided with an auxiliary fulcrum 220 corresponding to the central fulcrum 120 and capable of supporting the button assembly 300.

[0038] The extension bracket 210 and the mounting part 110 are designed to be separable, so that when the mounting part 110 of the middle cover 100 is deformed by force, the extension bracket 210 is less affected, the deformation of the auxiliary support point 220 is reduced, and it can maintain good support performance for the edge button, thereby improving the reliability of the switch base.

[0039] Specifically, the mounting part 110 is provided with a through hole for screws to pass through. When the switch base is assembled, the screw passes through the mounting part 110 and connects to the bottom box. The head of the screw presses against the mounting part 110. Since the main body of the middle cover 100 is a plate, the mounting part 110 is deformed by pressure when the screw is tightened. The extension frame 210 and the mounting part 110 are designed to be separable, that is, there is no direct connection structure. This makes the deformation of the mounting part 110 have little impact on the extension frame 210, so that the auxiliary support point 220 on the extension frame 210 can provide good support for the edge button and ensure its good pressing performance.

[0040] Of course, in the specific implementation process, the installation unit 110 may also be equipped with a snap-fit ​​installation structure, etc., to install the middle cover to the bottom box through snap-fit, which will not be described in detail here.

[0041] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, both ends of the extension frame 210 are connected to the inner support 200, and a clearance space 111 corresponding to the mounting part 110 is formed between the extension frame 210 and the inner support 200 to reduce contact with the mounting part 110.

[0042] Specifically, the extension frame 210 has a C-shaped structure, with its two ends connected to the inner support 200 to form a ring structure. A clearance space 111 corresponding to the mounting part 110 is formed in the middle. Both ends of the extension frame 210 are connected to the inner support 200, which can have good structural strength to provide sufficient support.

[0043] It is conceivable that, in some embodiments of the present invention, the auxiliary fulcrum 220 is located in the middle section of the extension frame 210, making the support more stable.

[0044] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the middle cover 100 is provided with a groove 101 corresponding to the extension frame 210, and the extension frame 210 is placed into the groove 101 to make the structure more compact.

[0045] Specifically, the groove 101 is distributed along the edge of the mounting part 110. When the mounting part 110 is not deformed, the extension frame 210 is close to the bottom of the groove 101 to support the extension frame 210. When the mounting part 110 is deformed by pressure, the extension frame 210 separates from the bottom of the groove 101, thereby forming a suspended structure and reducing the impact of the deformation of the mounting part 110 on the extension frame 210. In addition, the groove 101 can be used to hide the extension frame 210, which can reduce the occurrence of damage to the extension frame 210 during panel transportation or panel assembly.

[0046] It is understood that in some embodiments of the present invention, the groove 101 may not be configured, and the extension frame 210 may be directly suspended.

[0047] It is understood that in some embodiments of the present invention, the depth of the groove 101 may be set to be less than the thickness of the extension bracket 210, with a reserved amount of deformation so that the groove 101 can also support the button when the middle cover is installed.

[0048] like Figure 4 , Figure 5 As shown, in some embodiments of the present invention, the bottom of the extension frame 210 is provided with a notch 221 corresponding to the auxiliary fulcrum 220, so that an arched support structure is formed at the auxiliary fulcrum 220, which has good support force and is easy to elastically reset.

[0049] Specifically, the notch 221 corresponds to the pivot position of the switch control component 400. The inner bracket 200 is provided with a pivot hole. The inner bracket 200 is integrally formed by injection molding, which can directly form the pivot hole and the notch 221. The production process is simple. The elastic properties of the plastic, combined with the arched auxiliary support 220, make the auxiliary support 220 have good structural strength and a certain elasticity, resulting in a better feel when the button is pressed.

[0050] It is understood that in some embodiments of the present invention, the extension frame 210 is provided with a weakening structure to facilitate breaking or cutting the extension frame 210, so that the inner support 200 can be adapted to conventional panels.

[0051] Specifically, the weakening structure is preferably set at the connection position between the extension frame 210 and the inner support 200. The weakening structure can be a notch or a through hole, etc., to reduce the material at the corresponding position, so as to facilitate the breaking or cutting of the extension frame 210.

[0052] It is understood that, in some embodiments of the present invention, the weakening structure is a weakening notch provided on the side of the extension frame 210, which extends from top to bottom, so as to reduce the impact on the structural strength of the extension frame 210 in the vertical direction.

[0053] Specifically, during operation, the auxiliary support point 220 of the extension frame 210 is subjected to downward pressing force, and a weakening notch is opened laterally, which enables the extension frame 210 to maintain a certain thickness and maintain good shear resistance in the vertical direction. It is not easy to break during normal use, but the extension frame 210 can be easily broken when using tools to cut laterally or when pressed laterally by hand.

[0054] like Figure 2 As shown, in some embodiments of the present invention, the middle cover 100 is provided with a support portion 130 for mounting or supporting the inner bracket 200. The left and right sides of the support portion 130 are separated from the mounting portion 110 by a gap 131, which can reduce the impact of the mounting portion 110 on the support portion 130 and the inner bracket 200 when it deforms, thereby reducing the impact on the auxiliary support point 220 at the extension frame 210.

[0055] Specifically, the gap 131 separates the left and right sides of the support part 130 from the mounting part 110, so that the deformation of the mounting part 110 has little impact on the support part 130, thereby reducing the impact on the inner support 200. This ensures that the middle support point 120 of the inner support 200 and the auxiliary support point 220 of the extension frame 210 will not shift significantly, thus maintaining a good support effect.

[0056] like Figure 2 As shown, in some embodiments of the present invention, the front and rear ends of the support portion 130 are respectively connected to the middle cover 100, and the left and right sides of the support portion 130 can be separated from the middle cover 100, forming a narrow gap 131 on the side of the support portion 130 to reduce the influence of the mounting portion 110 on the support portion 130.

[0057] like Figure 3 As shown, in some embodiments of the present invention, the left and right sides of the middle cover 100 are respectively provided with outer support points 102, and the outer support points 102 correspond to the positions of the auxiliary support points 220 to provide auxiliary support for the outer buttons.

[0058] It is conceivable that, in some embodiments of the present invention, the extension frame 210 and the inner support 200 are an integral structure, which has good structural strength.

[0059] Specifically, the extension frame 210 and the inner support 200 are an integral structure formed by injection molding.

[0060] It is conceivable that, in some embodiments of the present invention, the two sides of the end of the extension frame 210 are respectively connected to the inner support 200 by a reinforcing structure to improve the structural strength of the extension frame 210.

[0061] Specifically, such as Figure 4 As shown, the inner side of the extension frame 210 is provided with a triangular reinforcing structure 211 connected to the inner support 200, and the outer side of the extension frame 210 is provided with an extension reinforcing structure 212 connected to the inner support 200, so that the end face, inner side and outer side of the extension frame 210 are all connected to the inner support 200, thereby improving the connection strength between the extension frame 210 and the inner support 200.

[0062] According to a second aspect of the present invention, the switch holder includes the button support structure of any of the first aspects of the present invention described above, which can improve the reliability of the switch holder.

[0063] Specifically, the switch holder includes a button support structure, a button assembly 300, and an electrical connection assembly 500, as described in any of the first aspects of the present invention. The button assembly 300, the switch control assembly 400, and the electrical connection assembly 500 are all mounted on the middle cover 100. The button assembly 300 is used to control the switch control assembly 400, and the electrical connection assembly 500 can be controlled to be switched on or off by the switch control assembly 400.

[0064] It is conceivable that, in some embodiments of the present invention, the middle cover 100 is provided with a support portion 130 for mounting or supporting the inner bracket 200. The left and right sides of the support portion 130 have gaps 131 with the mounting portion 110, which can reduce the impact of the mounting portion 110 on the support portion 130 and the inner bracket 200 when it deforms, thereby reducing the impact on the auxiliary support point 220 at the extension frame 210.

[0065] It is conceivable that, in some embodiments of the present invention, the inner bracket 200 partially abuts against the support portion 130, and the portion of the inner bracket 200 corresponding to the mounting structure is suspended relative to the support portion 130, so as to reduce the deformation of the inner bracket 200 during switch socket installation.

[0066] Specifically, when the middle cover 100 is installed with screws, the middle part of the main body of the middle cover 100 (located between the mounting structures) deforms significantly. The middle part of the support part 130 also undergoes slight deformation. By suspending the part of the inner bracket 200 corresponding to the mounting structure relative to the support part 130, that is, separating the middle part of the inner bracket 200 from the middle part of the support part 130, the offset of the inner bracket 200 is reduced, which can form a better fit with the button assembly 300, allowing the button assembly 300 to rotate normally.

[0067] like Figure 2 , Figure 7 As shown, in some embodiments of the present invention, the front and rear parts of the support portion 130 are respectively provided with support platforms 132, and the bottom of the front and rear parts of the inner support 200 are respectively provided with abutment protrusions 201 corresponding to the support platforms 132, so as to suspend the middle part of the inner support 200 and reduce its offset.

[0068] Specifically, the bottom of the inner support 200 has a square structure, and four abutment protrusions 201 are provided, which are respectively distributed at the four corners of the bottom of the inner support 200 to suspend the middle part of the inner support 200 and reduce the impact of the deformation of the middle part of the middle cover 100 on the inner support 200.

[0069] like Figure 2 As shown, in some embodiments of the present invention, the electrical connection assembly 500 includes a bottom housing 510 and an on / off control mechanism 520 disposed on the bottom housing 510. The inner bracket 200 and the bottom housing 510 are respectively located above and below the support portion 130 and connected by a connecting mechanism 530. The front and rear portions of the bottom housing 510 are provided with abutment portions 511 that abut against the bottom of the support portion 130, so that the inner bracket 200 and the bottom housing 510 are installed and fixed on the support portion 130. The positional offset of the switch control assembly 400 and the electrical connection assembly 500 is reduced by the setting of the gap 131.

[0070] Specifically, the main body of the contact part 511 is distributed at the corner of the bottom shell 510, which reduces the contact between the middle part of the bottom shell 510 and the middle part of the support part 130, and reduces the impact of the deformation of the middle part of the middle cover 100 on the bottom shell 510.

[0071] It is conceivable that in some embodiments of the present invention, the connecting mechanism 530 is a snap-fit ​​mechanism, and in specific implementation, it may also be a screw connection mechanism, etc.

[0072] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
