Description

Technical Field

[0001] The utility model relates to the field of electrical switches, and particularly to an ultra-thin switch with an integrated button. Background Art

[0002] In recent years, with the continuous improvement of people's requirements for home decoration effects and user experience, thin wall switches with a smaller volume have been welcomed by the market due to their simple appearance design and compact structure. These thin switches not only save space but also can better integrate into the modern home decoration style. Wall switches are usually assembled from multiple independent components, including but not limited to switch panels, buttons, bases, and internal electrical components.

[0003] However, for existing thin wall switches, due to the limitation of their volume, the switch panel is generally a whole and can only achieve single-button switch control. This design limits the functional diversity of the switch and cannot meet the user's demand for multi-way control. Although in some thin wall switches, the switch panel can achieve the control of two or three button switches, in this case, the switch panel is composed of three independent switch panels. Such an independent and separated design increases the manufacturing cost and assembly complexity, and at the same time makes the overall volume of the thin wall switch larger. Each switch panel needs to be produced and assembled separately, which not only increases the cost of raw materials but also raises the labor cost.

[0004] Therefore, how to overcome the above-mentioned existing defects has become an important issue that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0005] The utility model overcomes the above-mentioned technical deficiencies and provides an ultra-thin switch with an integrated button.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] An ultra-thin switch with an integrated button includes a base. An installation cavity is formed in the base, and a circuit board assembly is installed in the installation cavity. The upper end of the base is clamped with a pressing plate through a clamping structure. The pressing plate covers the installation cavity to press the circuit board assembly tightly in the installation cavity. The upper end of the pressing plate is connected with a button board. The button board is integrally formed. The button board includes a fixed end fixedly connected with the pressing plate and at least two independent movable ends extending towards one side of the fixed end. An isolation groove is formed between adjacent movable ends. When one of the movable ends is pressed, the movable end swings downward and abuts against the base. When the movable end is released, the movable end automatically resets.

[0008] Further, at least two first connection parts are provided below the fixed end. The first connection part includes a first clamping groove. A second clamping groove for the first connection part to be clamped into is correspondingly formed on the pressing plate. Limiting columns are formed on the inner wall surface of the second clamping groove. A guiding column for the first clamping groove to be clamped into to prevent the first connection part from disengaging from the second clamping groove is arranged in the second clamping groove. The guiding column is rotatably connected to the first clamping groove.

[0009] Further, a pressing column is provided below the movable end. A first through hole for the pressing column to penetrate into is correspondingly formed on the pressing plate. The circuit board assembly includes a button correspondingly formed below the first through hole and extending into the first through hole. When the movable end is pressed, the pressing column penetrates into the first through hole and presses the button.

[0010] Further, the pressing plate includes an inclined end sloping downward at the left end of the pressing plate. A second through hole is further formed in the inclined end. A limiting block is arranged in the second through hole. A second connection part clamped into the second through hole is further provided below the movable end. The second connection part includes a hook hooked on the limiting block on the left side and a guiding slope on the right side.

[0011] Further, the clamping structure includes third clamping grooves symmetrically formed on the upper and lower side walls of the pressing plate, and first buckles symmetrically formed on the upper and lower inner side walls of the base and clamped into the third clamping grooves.

[0012] Further, the clamping structure further includes fourth clamping grooves symmetrically formed on the left and right side walls of the pressing plate, and second buckles symmetrically formed on the left and right inner side walls of the base and clamped into the fourth clamping grooves.

[0013] Further, it further includes an AG glass panel fixedly connected to the upper end of the button board.

[0014] Further, the button board is made of pc material.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] An ultra-thin switch with an integrated button provided in this case presses a circuit board assembly tightly on a base through a pressing plate. The pressing plate is connected to the base through a clamping structure, simplifying the installation process and ensuring that the circuit board assembly is firmly fixed. At the same time, the setting of the pressing plate facilitates the connection of the button board. The button board adopts an integrally formed design, making the entire panel more compact and having better appearance consistency. The button board includes a fixed end fixedly connected to the pressing plate and at least two independent movable ends extending towards one side of the fixed end. An isolation groove is provided between adjacent movable ends, ensuring that each movable end can work independently without interference. The design of multiple independent movable ends enables users to more conveniently control different functions, such as controlling different circuit loops or devices. When one of the movable ends is pressed, the movable end swings downward and abuts against the base, and when the movable end is released, the movable end automatically resets, making the use operation convenient. The integrally formed design of the button board in this case can also achieve independent control of multiple switches through the cooperation of the fixed end and the movable end.

[0023] The following further details the features of the present utility model and other related features through embodiments for the understanding of those skilled in the same industry:

[0024] Regarding the descriptions of the positional relationships of components such as front, back, top, bottom, left, and right in this case, please refer to Figure 1 、 Figure 2 、 Figure 4The orientation shown in

[0025] As Figures 1 to 6 shown, this case provides a thin switch with an integrated button, including a base 100. An installation cavity 101 is formed on the base 100, and a circuit board assembly 1 is installed in the installation cavity 101. The installation cavity 101 is provided to accommodate and fixedly install the circuit board assembly 1, protect the circuit board assembly 1 from the influence of the external environment, ensure that the circuit board assembly 1 can be reliably installed and operate, and facilitate the installation of other components on the base 100. A pressing plate 2 is clamped to the upper end of the base 100 through a clamping structure. The pressing plate 2 covers the installation cavity 101 to press the circuit board assembly 1 tightly in the installation cavity 101. The pressing plate 2 is connected to the base 100 through a clamping structure, which simplifies the installation process and improves the assembly efficiency; at the same time, it can ensure that the circuit board assembly 1 is firmly fixed and not easily loosened. The upper end of the pressing plate 2 is connected to a button board 3. The button board 3 is integrally formed. Compared with the prior art, it reduces the assembly steps, reduces the production cost, and reduces the assembly gap, making the whole button board 3 more compact and having better appearance consistency, which is beneficial to further reducing the thickness of the thin switch with the integrated button in this case. The button board 3 includes a fixed end 31 fixedly connected to the pressing plate 2 and at least two independent movable ends 32 extending toward the fixed end 31. Users can easily control multiple circuits by pressing different movable ends 32, improving the flexibility and convenience of use. Specifically, when implemented, the movable ends 32 can be two, three, four or more. An isolation groove 33 is formed between adjacent movable ends 32. The isolation groove 33 ensures the independent movement between adjacent movable ends and avoids mutual interference. Specifically refer to Figure 2 shown, the fixed end 31 is an integrally formed end located on the right side of the button board 3, which is used to connect to the pressing plate 2 to fix the right end of the button board 3. The movable ends 32 are at least two movable ends 32 extending leftward along the fixed end 31. The adjacent movable ends 32 are separated by the isolation groove 33 to make them independent of each other. Specifically, when implemented, the length of the fixed end 31 is less than the length of the movable ends 32 to facilitate the pressing of the movable ends 32. When one of the movable ends 32 is pressed, the movable end 32 swings downward and abuts against the base 100, thereby transmitting mechanical force to the circuit board assembly 1 to trigger the corresponding switch action. When the movable end 32 is released, the movable end 32 automatically resets to ensure that the switch can return to the initial state after each operation and be ready for the next operation, which is convenient for operation.

[0026] Furthermore, refer to Figures 1 - 5As shown in the figure, there are at least two first connecting parts 311 provided below the fixed end 31. The first connecting part 311 includes a first clamping groove 3111. The first connecting part 311 can be set according to requirements to ensure the stability of the connection between the fixed end 31 and the pressing plate 2. A second clamping groove 21 for the first connecting part 311 to be inserted into is correspondingly opened on the pressing plate 2. A limiting post 211 is formed on the inner wall surface of the second clamping groove 21. The first connecting part 311 is inserted into the second clamping groove 21, so as to realize the clamping connection between the fixed end 31 and the pressing plate 2. By pressing the first connecting part 311 in the second clamping groove 21 with the limiting post 211, it can prevent the first connecting part 311 from coming out of the second clamping groove 21 when the user presses the movable end 32 of the key board 3 to operate the switch. In specific implementation, in order to stably limit and press the first connecting part 311, the limiting posts 211 are symmetrically arranged. Two or four or other plural numbers can be set. In this case, four are preferably set, which is more stable and easier to install. A guiding post 212 is provided in the second clamping groove 21 for the first clamping groove 3111 to be inserted into to prevent the first connecting part 311 from coming out of the second clamping groove 21. The guiding post 212 is rotatably connected to the first clamping groove 3111. That is to say, when the user presses the movable end 32 of the key board 3, the first clamping groove 3111 of the fixed end 31 will rotate around the guiding post 212, improving the guiding effect and restricting the downward pressing stroke of the key board 3. In specific implementation, the first clamping groove 3111 is an unclosed large arc shape. To match the first clamping groove 3111, the upper end of the guiding post 212 is a triangular body and the lower end is a semi-cylindrical body, so that the guiding post 212 will not come out of the first clamping groove 3111 even when rotating after being inserted. To facilitate the connection between the first connecting part 311 and the second clamping groove 21, the guiding post 212 is arranged in the middle of the second clamping groove 21, dividing the second clamping groove 21 into two parts. Through the cooperation between the guiding post 212 and the first clamping groove 3111, the guiding effect is further improved, making the action of pressing the movable end 32 smoother. At the same time, it can also limit the downward pressing stroke of the key board, reducing the situation of pressing and damaging the button 11 on the circuit board assembly 1. Through the combined action of the limiting post 211 and the guiding post 212, it is ensured that when the user presses the movable end 32 of the key board 3 to operate the switch, the fixed end 31 will not come out of the pressing plate 2, ensuring the stability of the structure.

[0027] Further, referring to Figures 1 - 5As shown in the figure, a pressing column 321 is provided below the movable end 32. The pressing column 321 is integrally formed with the movable end 32. When the movable end 32 is pressed, the pressing column 321 moves downward accordingly. A first through hole 22 for the pressing column 321 to penetrate is correspondingly formed on the pressing plate 2, so that the pressing column 321 can smoothly penetrate the pressing plate 3 when the movable end 32 is pressed. Through the precise cooperation of the pressing column 321 and the first through hole 22, it is ensured that when the movable end 32 is pressed, the button 11 can be accurately pressed, realizing the precise control of the switch. The circuit board assembly 1 includes a button 11 correspondingly formed below the first through hole 22 and extending into the first through hole 22. When the movable end 32 is pressed, the pressing column 321 penetrates into the first through hole 22 and presses the button 11, thereby triggering the closing or opening of the switch. The direct contact between the pressing column 321 and the button 11 reduces the delay in the transmission process and improves the response speed of the switch. This simple mechanical connection method reduces the complexity inside the switch, makes the whole structure more compact, and is beneficial to further reducing the thickness of the ultra-thin switch of the integrated button in this case.

[0028] Referring to Figures 1 - 5 As shown in the figure, further, the pressing plate 2 includes an inclined end 201 that slopes downward at the left end of the pressing plate 2. When the button plate 3 is installed on the pressing plate, by setting the inclined end 201, a gap is left between the movable end 32 and the inclined end 201 for the movable end 32 to press down to realize the switch function. At the same time, the maximum pressing distance of the movable end 32 is limited to prevent damage caused by excessive pressing. A second through hole 23 is also formed on the inclined end 201. A limiting block 231 is provided in the second through hole 23. A second connecting portion 322 that is snapped into the second through hole 23 is also provided below the movable end 32. The second connecting portion 322 includes a hook 3221 that is hooked on the limiting block 231 on the left side and a guiding slope 3222 on the right side. Specifically, during implementation, the second through hole 23 and the second connecting portion 322 are arranged in one-to-one correspondence. The first through hole 22 is formed on the inclined end 201, and the second connecting portion 322 is provided at a position directly below the movable end 32 and opposite to the second through hole 23. The hook 3221 cooperates with the limiting block 231 to enable the movable end 32 to automatically rebound and reset after being pressed, preventing the movable end 32 from bouncing too high and deviating from the initial position. The guiding slope 3222 on the right side facilitates the smooth pressing down of the movable end. The design of the guiding slope 3222 enables the second connecting portion 322 to move smoothly along the second through hole 23 when the movable end 32 is pressed, ensuring the smoothness during the pressing process.

[0029] As Figure 1 、 Figure 4 、 Figure 5As shown in the figure, specifically, the snap-fit structure of this case includes third card slots 24 symmetrically opened on the upper and lower side walls of the pressing plate 2, and first snap-buckles 102 that are symmetrically opened on the upper and lower inner side walls of the base 100 and snap into the third card slots 24. During specific implementation, the number of the first snap-buckles 102 is set to two, and they are symmetrically arranged up and down on the side wall of the pressing plate 2. There are two sets of the third card slots 24 and the first snap-buckles 102 in cooperation, which are also symmetrically arranged up and down on the inner side wall of the base 100. Through the snap-fit cooperation of the third card slots 24 and the first snap-buckles 102, the rapid installation and disassembly between the pressing plate 2 and the base 100 are realized, and the assembly process is simplified. The first snap-buckles 102 and the third card slots 24 that are symmetrically arranged up and down ensure the stable connection between the pressing plate 2 and the base 100, and prevent loosening or falling off during use. The snap-fit structure set in this case helps to ensure the accurate alignment between the pressing plate 2 and the base 100, thereby improving the assembly accuracy and the sealing performance between the pressing plate 2 and the base 100.

[0030] Furthermore, as Figure 1 , Figure 4 , Figure 5 shown, as the preferred implementation mode of this case, to further improve the stability and sealing performance of the connection between the pressing plate 2 and the base 100, the snap-fit structure of this case further includes fourth card slots 25 symmetrically opened on the left and right side walls of the pressing plate 2, and second snap-buckles 103 that are symmetrically opened on the left and right inner side walls of the base 100 and snap into the fourth card slots 25. The connection relationship, functions, and effects of the fourth card slots 25 and the second snap-buckles 103 refer to the description of the first snap-buckles 102 and the third card slots 24 above, and will not be elaborated here. It should be noted that during specific implementation, in order to make the connection between the pressing plate 2 and the base 100 more stable, preferably, the number of the second snap-buckles 103 is set to four, and they are symmetrically arranged left and right, and there are four sets of the fourth card slots 25 in cooperation, which are also symmetrically arranged left and right.

[0031] As Figure 1 shown, the ultra-thin switch of the integrated button in this case further includes an AG glass panel 4 fixedly connected to the upper end of the button board 3. The AG glass panel has a good anti-glare effect, reduces light reflection, and improves the visual comfort of users. The AG glass panel has a high hardness, can effectively resist scratches and abrasions, extends the service life of the product, and can provide a good touch feeling for users at the same time, improving the user experience. The button board 3 in this case is made of pc material, and this material has good mechanical strength and heat resistance to ensure the durability of the button board 3 under long-term pressing.

[0032] As described above, what this case protects is an ultra-thin switch of an integrated button, and all technical solutions that are the same as or similar to this case should be regarded as falling within the protection scope of this case.
