DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The purpose of the present invention is to provide a push button switch to solve the problems existing in the prior art, realize diversified design of button size and arrangement, and enhance the versatility of the push button switch and its adaptability to different usage environments.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1 to 8As shown, this embodiment provides a button 2 switch, including a circuit board 1, a mounting portion, a button 2 and an elastic member; a row or multiple rows of functional areas 3 are arranged at even intervals on the circuit board 1, and multiple micro buttons 11 are evenly spaced in each functional area 3, and the micro buttons 11 are used to control the on and off of the load circuit. The circuit board 1 is fixed in the cavity of the mounting part; a pressing channel 4 and a card interface 5 are provided on the mounting part, and the pressing channel 4 corresponds to the position of the functional area 3; the card interfaces 5 are distributed on both sides of the pressing channel 4 and are used to install the button 2, and multiple card interfaces 5 are arranged at intervals along the arrangement direction of the micro-switch buttons 11 in a functional area 3; an abutment column 6 and a connecting column 7 are provided on the back of the button 2, and the abutment column 6 extends into the pressing channel 4 and is arranged opposite to the micro-switch button 11 for pressing the micro-switch button 11, and the connecting column 7 is slidably set in the card interface 5, and a card block 8 that can be engaged with the card interface 5 and limited is provided on the end of the connecting column 7 away from the back of the button 2; one end of the elastic member is connected to the mounting part or the circuit board 1, and the other end is connected to the button 2, for providing a reset force to the button 2 after being pressed. When button 2 is pressed, the micro-switch 11 is pressed via the abutment column 6 to turn the load on, off, or switch modes. For example, if the load controlled by button 2 is a light, pressing button 2 once turns the light on. Pressing button 2 again turns the light off or switches the light's mode, such as changing the light's color or flashing it. Finally, pressing button 2 turns the light off. The connection column 7 cooperates with the card interface 5 to guide the button 2, ensuring its fixed position. The provision of the clamping block 8 prevents the button 2 from disengaging from the mounting portion due to the elastic force of the elastic member. In this embodiment, the connection column 7 and the clamping block 8 form a barbed hook structure.

[0040] Since a plurality of micro-switch buttons 11 are provided in a functional area 3 in this embodiment, and a plurality of card interfaces 5 distributed along the arrangement direction of the micro-switch buttons 11 are provided on both sides of the functional area 3, the size and arrangement of the buttons 2 can be adjusted during the design and arrangement of the buttons 2. For example, if there are a total of four card interfaces 5 facing each other on both sides of the functional area 3 (in actual design, the card interfaces 5 do not necessarily have to face each other, but they should be ensured to be not too far apart in the direction perpendicular to the facing direction, and ensure that one button 2 cooperates with at least two card interfaces 5), for a button 2 with a small area (hereinafter referred to as a small button), two relatively set card interfaces 5 can be used for card connection, and the abutment column 6 on the middle button corresponds to the micro-switch button 11 at the inner edge position of the functional area 3. For a button 2 with a slightly larger area (hereinafter referred to as a middle button), four card interfaces 5 can be used for card connection, that is, one middle button covers the entire functional area 3, and the abutment column 6 on the middle button corresponds to the micro-switch button 11 in the middle position of the functional area 3; if there are multiple functional areas 3, for example, 2 or more, and each functional area 3 has 4 card interfaces 5 on both sides, then a button 2 with a larger area (hereinafter referred to as a large button) can be installed, and one button 2 covers 2 or more functional areas 3. Of course, the area of ​​the large button is designed according to actual conditions. Thus, in this embodiment, by setting one or more functional areas 3, setting multiple micro-buttons 11 in the functional areas 3, and setting multiple card interfaces 5 on both sides of the functional areas 3, one or more buttons 2 can be installed on one functional area 3, and the multiple micro-buttons 11 in the functional area 3 can meet the use of one or more buttons 2, thereby realizing diversified design of the size and arrangement of the buttons 2, enhancing the versatility of the button switch in this embodiment and its adaptability to different usage environments.

[0041] In this embodiment, there are four function areas 3, and each function area 3 is provided with three micro buttons 11. Thus, one function area 3 can be provided with two small buttons or one medium button, and two function areas 3 can be provided with one large button. Therefore, when the button 2 switch in this embodiment only includes the above-mentioned large button, medium button and small button, there can be 44 kinds of button 2 arrangement forms, such as Figure 7 shown.

[0042] In this embodiment, a micro-switch button 11 is further provided between adjacent functional areas 3 on the circuit board 1, and a pressing hole for pressing the micro-switch button 11 at this position is provided on the mounting portion. When a large button is provided, an abutment column 6 is provided at the center position of the back of the large button for abutting the micro-switch button 11 to realize the on / off control of the load. In this embodiment, there are a total of 15 micro-switch buttons 11, such as Figure 3 shown.

[0043] In this embodiment, the function area 3 is also provided with multiple backlights 12, spaced apart along the arrangement of the micro-switch buttons 11. The backlights 12 can be LEDs. Specifically, in this embodiment, four backlights 12 are provided in the function area 3, alternating with the micro-switch buttons 11. Adjacent function areas 3 are separated by press channels 4 to prevent backlights 12 in different function areas 3 from interfering with each other. The button 2 is provided with a light-transmitting area and / or light bar 10. The button 2 is made of translucent plastic. The surface of the button 2 is shielded from light by spray painting, and then laser engraved with different text and / or patterns to produce the desired backlight pattern. In this embodiment, the color and mode of each backlight 12 can be individually controlled to achieve various backlighting functions for the button 2. If a light bar 10 is provided on the button 2, a corresponding light bar socket 22 for mounting the light bar 10 is provided on the button 2.

[0044] In this embodiment, a shading plate 9 is provided on the back of the button along the pressing direction of the button 2. The shading plate 9 is used to separate the backlights 12 in the functional area 3 to prevent adjacent backlights 12 from affecting each other. Figure 5 ,、 Figure 6 For example, a small button may correspond to two backlights 12 , one for illuminating the light bar 10 and the other for illuminating the light bar 10 . The light shield 9 on the button 2 can separate the light emitted by the two backlights 12 to a certain extent.

[0045] It should be noted that during the design phase for the size and layout of the buttons 2, the number, color, and illumination pattern of the backlights 12, as well as the control mode of the micro-switch buttons 11, must be set. Not all of the backlights 12 and micro-switch buttons 11 in the function area 3 need to be used; some can be selected based on actual circumstances. When the size and layout of the buttons 2 are changed, the existing illumination pattern of the backlights 12 and the control mode of the micro-switch buttons 11 can be redesigned.

[0046] In this embodiment, the elastic member may include an elastic cantilever, one end of which is fixed to the edge of the mounting portion, and the other end of which extends laterally into the inner side of the mounting portion and abuts against the back surface of the button 2 .

[0047] As another structural form of the elastic member, the elastic member includes a compression spring 13, one end of which abuts the mounting portion or circuit board 1, and the other end abuts the back surface of the button 2. In this embodiment, one end of the compression spring 13 can be sleeved on the outside of the micro-switch button 11, and the other end can be sleeved on the end of the abutment column 6.

[0048] This embodiment further includes a power board 21 , which is disposed in the mounting portion and is communicatively connected to the circuit board 1 .

[0049] In this embodiment, the mounting portion includes a trough body 14, a top cover 15, and a frame. The trough body 14 and the top cover 15 can form a housing for accommodating the power board 21 and the circuit board 1. The trough body 14 is used to accommodate the circuit board 1; the top cover 15 is detachably fixed to the notch of the trough body 14 by bolts; the top cover 15 is provided with a pressing channel 4 oriented in the same direction as the notch. In this embodiment, the pressing channel 4 is rectangular in shape. Along the notch, the projection area of ​​the pressing channel 4 on the circuit board 1 is the functional area 3; the frame is fixedly connected to the top cover 15, and the frame includes a frame edge 16 and a flat plate 17 connected to the inner side of the frame edge 16. The flat plate 17 is provided with multiple openings 18 at intervals, and the openings 18 are arranged on the outer side of the pressing channel 4; there is a gap between the flat plate 17 and the top cover 15, and the flat plate 17 is also provided with a card interface 5.

[0050] This embodiment also includes a mounting bracket 19, which is used to secure the button 2, mounting portion, and other components to a fixed structure, such as a wall. Mounting bracket 19 can be shaped like a flat plate 17 and can be bolted to a reserved switch location on the wall. The top cover 15 is removably connected to the mounting bracket 19 using bolts, and the frame is removably connected to the mounting bracket 19 using a barbed-shaped snap-fit ​​structure.

[0051] This embodiment also includes a frame-shaped buckle cover 20, which is detachably connected to the mounting bracket 19. The frame edge 16 and the button 2 are exposed from the buckle cover 20. Specifically, the buckle cover 20 can be snap-fitted or bolted to the mounting bracket 19 to completely cover the reserved position of the switch on the wall to ensure an aesthetically pleasing appearance.

[0052] like Figure 8 As shown, the modules integrated on the circuit board 1 include:

[0053] 1. Matrix micro-switch button 11 disk. In order to realize various combinations of physical buttons, the micro-switch buttons 11 need to adapt to the positions of different physical buttons. In this embodiment, a keyboard with 4×3+3 micro-switch buttons 11 in total is used.

[0054] 2. Matrix backlight 12. In order to achieve personalized lighting effects for each button, this embodiment uses 4×4 16 RGB lights to form a backlight 12 module.
