Description

Technical Field

[0001] The invention relates to the field of electrical technology, and in particular to an ultra-thin switch driven at a small angle. Background Art

[0002] At present, wall switches have been widely used in people's daily life. Existing wall switches often adopt a seesaw switch structure. Traditional wall switches are generally thicker (about 10mm). The internal structure is a button seesaw, a mounting bracket, a rocker, an upper cover, a bottom shell, a moving contact piece, a static contact piece, a wiring terminal and a fixing part. The button seesaw and the rocker are matched in such a way that the rocker is buckled with the buckle of the button seesaw so that the axis of the rocker remains unchanged and is driven to flip in the original position. The mounting bracket is a carrier for carrying the button seesaw and the driving part. It is fixed to the wall with the concealed bottom box embedded in the wall when used for home installation. When the user turns on the light at home, he directly touches the button seesaw to make the button seesaw press the rocker to directly swing 5°, and the moving contact piece The user presses the button again to disconnect the circuit between the moving contact and the static contact, and the light bulb stops working, thereby closing and disconnecting the circuit. However, this traditional switch directly drives the moving contact with the pressing force of the transmission method. This structure requires a large-angle driving stroke to enable the switch current to be transmitted normally. This large-angle switch will easily get stuck and stop working, causing the user to press hard when using it. After pressing hard, it will also be accompanied by a harsh noise that makes the user uncomfortable. In addition, the driving angle of the traditional switch is too large, causing the appearance of the operating part exposed on the wall to appear thick and abrupt after the switch is installed on the wall. It cannot be the best choice in some places with high requirements and aesthetics. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an ultra-thin switch with a small-angle drive, which solves the problem that the switch structure in the prior art requires a large-angle drive stroke to enable the switch current to be transmitted normally, thereby causing the switch to easily get stuck and stop working, and the operating part exposed on the wall appears thick and abrupt.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultra-thin switch driven at a small angle, comprising a shell, a moving contact piece is installed in the shell, a key rocker is swingably installed above the shell, and a driving member for driving the two ends of the moving contact piece to swing is installed between the key rocker and the shell, wherein the driving member comprises a first rocker rod and a second rocker rod, the first rocker rod is slidably installed in the shell, the second rocker rod is swingably installed in the shell, the key rocker is in contact with the first rocker rod, and when the key rocker is subjected to pressing force, the first rocker rod is driven to slide, thereby driving the second rocker rod to swing, and the second rocker rod drives the moving contact piece to swing, thereby realizing the conduction or disconnection of the switch circuit.

[0005] As a further improvement of the above technical solution:

[0006] The shell comprises an upper cover and a bottom shell, and the upper cover and the bottom shell are buckled and installed.

[0007] The first swing rod is slidably mounted on the upper cover, the second swing rod is swingably mounted on the upper cover, the button rocker is swingably mounted above the upper cover, the first swing rod abuts against the upper cover, the top of the second swing rod is connected to the first swing rod, the bottom of the second swing rod abuts against the upper surface of the moving contact piece, and the moving contact piece is swingably mounted in the bottom shell.

[0008] The two side walls of the upper cover are provided with oblique waist grooves, and the first swing rod is provided with a sliding column at the position corresponding to the waist groove. The sliding column is slidably installed in the waist groove, and the two ends of the first swing rod are in contact with the button rocker. When the button rocker is subjected to pressing force, the first swing rod is driven to slide along the waist groove.

[0009] A first through hole is opened in the middle of the upper cover, a first mounting seat is arranged outside the first through hole, the second swing rod passes through the first through hole and is swingably mounted on the first mounting seat, the top end of the second swing rod is connected to the first swing rod, and the bottom of the second swing rod is in contact with the moving contact piece.

[0010] A second through hole is opened in the middle of the first swing rod, two arc-shaped holding plates are symmetrically arranged outside the second through hole, the top end of the second swing rod passes through the second through hole, and the two arc-shaped holding plates hold the second swing rod.

[0011] A common-end conductive sheet, a left static contact sheet and a right static contact sheet are also provided in the bottom shell. The left static contact sheet and the right static contact sheet are spaced apart from each other on the left and right sides. One end of the common-end conductive sheet abuts against the middle position of the bottom of the moving contact sheet, and the other end of the common-end conductive sheet is connected to the common-end wiring terminal. The moving contact sheet is located between the left static contact sheet and the right static contact sheet, the left static contact sheet is connected to the left wiring terminal, and the right static contact sheet is connected to the right wiring terminal. The moving contact sheet swings to contact or separate from the left static contact sheet and the right static contact sheet to realize the conduction or disconnection of the switch circuit.

[0012] The switch also includes a mounting bracket and a mounting iron plate, wherein the mounting iron plate is buckled and mounted on the bottom of the mounting bracket, the key rocker is swingably mounted on the top of the mounting bracket, and the upper cover is buckled and mounted on the mounting bracket and the mounting iron plate.

[0015] Compared with the prior art, the above technical solution brings the following technical effects:

[0016] Compared with the traditional switch, the button rocker adopts a buckling method to connect a rocker rod. When the button rocker is pressed, it swings 5°, so that the axis of the rocker rod remains unchanged and flips 5° in the original position to drive the moving contact piece. The driving member for driving the two ends of the moving contact piece to swing in the present invention includes a first rocker rod and a second rocker rod, and the first rocker rod is slidably installed in the shell. The first rocker rod slides obliquely during the driving process, and the axis will change with the driving direction instead of flipping in a direction. The second rocker rod is swingably installed in the shell. The second rocker rod is flipped and toggled in a direction when driven, and the axis will not change in the original position. After one side of the button rocker is pressed, the first rocker rod is driven to slide toward the side without force, and the first rocker rod drives the second rocker rod connected thereto to swing, and then the second rocker rod drives the moving contact piece to contact The static contact piece enables it to achieve the ability to close and disconnect the current. Since the first swing arm slides obliquely after being driven by the driving force of the key rocker, the horizontal component force applied by the first swing arm to the second swing arm can drive the second swing arm to swing significantly. Therefore, the key rocker only needs to swing a small angle of 2° to make the second swing arm swing a 5° stroke to achieve the closing and disconnection of the circuit. The movement stroke of the key rocker is reduced, thereby reducing the thickness of the switch product protruding from the wall and improving the aesthetics of the product. When in use, the user only needs to press lightly to achieve the closing and disconnection of the circuit, avoiding pressing the key rocker hard to cause the key rocker to get stuck and stop working. At the same time, it avoids the harsh noise caused by the impact of the key rocker after being pressed hard, which brings users a better operating experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0033] like Figures 1 to 8 As shown, the ultra-thin switch with small-angle drive in this embodiment includes a shell 1, a moving contact piece 2 is installed in the shell 1, a key rocker 3 is swingably installed above the shell 1, and a driving member 4 for driving the two ends of the moving contact piece 2 to swing is installed between the key rocker 3 and the shell 1, wherein the driving member 4 includes a first swing rod 41 and a second swing rod 42, the first swing rod 41 is slidably installed in the shell 1, and the second swing rod 42 is swingably installed in the shell 1, the key rocker 3 abuts against the first swing rod 41, and the first swing rod 41 cooperates with the second swing rod 42, when the key rocker 3 is pressed, the first swing rod 41 is driven to slide, thereby driving the second swing rod 42 to swing, and the second swing rod 42 drives the moving contact piece 2 to swing, so as to realize the conduction or disconnection of the switch circuit.

[0034] The first swing rod 41 is slidably installed in the shell 1. The first swing rod 41 slides obliquely during the driving process, similar to the movement trajectory of a pirate ship. The axis will change with the driving direction instead of flipping in a directional manner. One end of the first swing rod 41 abuts against the key rocker 3, and the other end cooperates with the second swing rod 42. The second swing rod 42 is swingably installed in the shell 1. The second swing rod 42 flips and toggles in a directional manner during driving, and the axis will not change in the original position. One end of the second swing rod 42 cooperates with the first swing rod 41, and the other end is connected to the moving contact piece 2. Pressing points are provided on the outer surfaces of both ends of the key rocker 3. When the user presses the pressing point at one end of the key rocker 3, the one end of the key rocker 3 is subjected to the pressing force and drives the first swing rod 41 to slide obliquely toward the side without force, thereby driving the second swing rod 42 to swing. The swing of the second swing rod 42 is achieved through its contact with the moving contact piece 2 The key rocker 3 is connected to the housing 1 to drive the movable contact piece 2 to swing in the housing 1, thereby realizing the conduction or disconnection of the circuit. Since the first swing rod 41 slides obliquely after receiving the driving force from one end of the key rocker 3, the horizontal component force applied by the first swing rod 41 to the second swing rod 42 can drive the second swing rod 42 to swing significantly. Therefore, the key rocker 3 only needs to swing a small angle of 2° to make the second swing rod 42 swing a 5° stroke to realize the closing and disconnection of the circuit. The movement stroke of the key rocker 3 is reduced, thereby reducing the thickness of the switch product protruding from the wall and improving the aesthetics of the product. When using, the user only needs to press lightly to realize the closing and disconnection of the circuit, avoiding pressing the key rocker 3 hard to cause the key rocker 3 to get stuck and stop working, and at the same time, avoiding the key rocker 3 to be hit after being pressed hard to produce a harsh noise.

[0035] The present invention not only realizes a compact structure and reduces the thickness of the protruding wall of the switch product, but also improves the driving efficiency and operating feel through an optimized design of the driving member 4, thereby meeting the demand of modern electronic equipment for ultra-thin switches.

[0036] In this embodiment, in order to improve the sensitivity and durability of the switch, the first swing rod 41 and the second swing rod 42 can be made of stainless steel to ensure their strength and corrosion resistance.

[0037] In this embodiment, the housing 1 includes an upper cover 101 and a bottom shell 102 , and the upper cover 101 and the bottom shell 102 are buckled and installed.

[0038] like Figure 3As shown, a groove structure is designed on the upper cover 101, and a buckle structure is designed on the bottom shell 102. The buckle structure and the groove structure are buckled with each other. Of course, a buckle structure can also be designed on the upper cover 101, and a groove structure can be designed on the upper cover 101. The shape and size of the buckle structure and the groove structure match to ensure that the upper cover 101 can be accurately buckled with the bottom shell 102. Buckling process: When assembling the shell 1, first place the upper cover 101 on the top of the bottom shell 102 to align the buckle structure with the groove structure. Then, gradually press along the edge of the bottom shell 102 so that the buckle structure is gradually embedded in the groove structure until the edges of the bottom shell 102 are completely buckled with the upper cover 101.

[0039] In order to ensure the sealing of the housing 1 and protect the internal components from being damaged by dust and moisture, a sealing edge is designed on the lower surface of the upper cover 101 corresponding to the buckling edge of the bottom shell 102.

[0040] Through the above design, the upper cover 101 and the bottom shell 102 of the housing 1 can not only realize fast and accurate snap-fit ​​installation, but also have good sealing and strength, providing stable and safe protection for the internal moving contact piece 2, key rocker 3 and driving member 4. This housing structure is suitable for the design of various ultra-thin switches.

[0041] In this embodiment, the first swing rod 41 is slidably installed on the upper cover 101, the second swing rod 42 is swingably installed on the upper cover 101, the key rocker 3 is swingably installed above the upper cover 101, the first swing rod 41 abuts against the upper cover 101, the top of the second swing rod 42 is connected to the first swing rod 41, the bottom of the second swing rod 42 abuts against the upper surface of the moving contact piece 2, and the moving contact piece 2 is swingably installed in the bottom shell 102.

[0042] The first swing rod 41 is slidably installed in the upper cover 101. The first swing rod 41 slides obliquely during the driving process. The axis will change with the driving direction instead of being flipped and moved in a directional manner. Specifically, an oblique waist groove 1011 is opened on the two side walls of the upper cover 101, and a sliding column 411 is provided at the position of the first swing rod 41 corresponding to the waist groove 1011. The sliding column 411 is slidably installed in the waist groove 1011. The two ends of the first swing rod 41 are in contact with the button rocker 3. When the button rocker 3 is pressed, the first swing rod 41 is driven to slide obliquely left and right along the waist groove 1011.

[0043] The upper cover 101 in this embodiment is a component of the housing 1, and its two side walls are provided with oblique waist grooves 1011. The design of the oblique waist grooves 1011 allows the first swing rod 41 to slide inside thereof, thereby realizing the driving conversion of the pressing action of the key rocker 3 to the second swing rod 42 and the moving contact piece 2. The waist grooves 1011 are provided on the two side walls of the upper cover 101, and are in the shape of oblique grooves, so that the first swing rod 41 can slide inside thereof. The slope and size of the waist grooves 1011 are determined according to the moving range of the first swing rod 41 and the required driving force. The first swing rod 41 is provided with a sliding column 411 at the position corresponding to the waist groove 1011. The sliding column 411 is a component of the first swing rod 41, and its shape and size match the waist groove 1011 to ensure that the sliding column 411 can slide smoothly in the waist groove 1011. The sliding column 411 is slidably installed in the waist groove 1011, and its installation method can be achieved by direct insertion. The sliding surface of the slide post 411 can be designed to reduce friction in order to reduce friction during the sliding process and improve the sliding efficiency. The two ends of the first swing rod 41 abut against the key rocker 3. The abutment in this embodiment is through direct contact. When one end of the key rocker 3 is pressed, the key rocker 3 swings 2°. One end of the first swing rod 41 is firstly acted upon by the force, and then slides along the waist groove 1011, thereby driving the second swing rod 42 connected to the first swing rod 41 to swing 5°. The second swing rod 42 drives the moving contact piece 2 to swing and contact or disconnect with the stationary contact piece, thereby realizing the conduction or disconnection of the switch circuit.

[0044] Through the above-mentioned structural design, the key rocker 3 exposed on the wall after installation has only a movement stroke of an angle of 2°, thereby reducing the use of internal space and making the product appearance thickness thinner to 5.5mm. The traditional switch pressing requires a movement stroke of an angle of 5°, so the appearance thickness is 10mm. The ultra-thin switch driven at a small angle in this embodiment not only achieves a compact structure and a thinning of the thickness of the switch product protruding from the wall, but also improves the driving efficiency and operating feel through the optimized design of the driving member 4, meeting the needs of modern electronic devices for ultra-thin switches. At the same time, the stability and reliability of the switch are ensured through precise installation and connection methods. In addition, the design of the oblique waist groove 1011 makes the pressing action of the key rocker 3 smoother, improving the user experience.

[0045] In this embodiment, a first through hole 1012 is opened in the middle of the upper cover 101, and a first mounting seat 1013 is arranged outside the first through hole 1012. The second swing rod 42 passes through the first through hole 1012 and is swingably mounted on the first mounting seat 1013. The top of the second swing rod 42 is connected to the first swing rod 41, and the bottom of the second swing rod 42 is in contact with the moving contact piece 2.

[0046] The second swing rod 42 is flipped and toggled in a directional manner when driven, and the axis will not change in the original position. The bottom of the second swing rod 42 abuts against the upper surface of the movable contact piece 2. Specifically, by setting an abutment portion at the bottom of the second swing rod 42, the upper surfaces of both ends of the movable contact piece 2 are designed with energized contacts. When the abutment portion contacts the energized contact on one side, the side is energized. The movable contact piece 2 is swingably installed in the bottom shell 102. Specifically, two swing blocks are symmetrically arranged on both side walls of the middle part of the movable contact piece 2. The two swing blocks are coaxially arranged. Two swing slots are arranged in the bottom shell 102. The two swing blocks are respectively inserted in the two swing slots. The movable contact piece 2 is swingably installed in the bottom shell 102 through the swing blocks and the swing slots.

[0047] The size and shape of the first through hole 1012 are designed according to the diameter and swing range of the second swing rod 42 to ensure that the second swing rod 42 can swing freely in the first through hole 1012, so that the abutment portion of the second swing rod 42 can contact the energized contacts at both ends of the movable contact piece 2.

[0048] A first mounting seat 1013 is disposed outside the first through hole 1012 . The first mounting seat 1013 is a part of the upper cover 101 and is designed to fix and support the swing end of the second swing rod 42 .

[0049] The second swing rod 42 passes through the first through hole 1012 and is swingably mounted on the first mounting seat 1013. One end of the second swing rod 42 extends out of the first through hole 1012 and is mounted in the first mounting seat 1013, and the other end passes through the first through hole 1012 and abuts against the movable contact piece 2. The swing of the second swing rod 42 can be achieved by designing a swing pin on the side wall of the second swing rod 42, and a pin hole is provided on the first mounting seat 1013 corresponding to the position of the swing pin, and the swing pin is inserted and installed in the pin hole.

[0050] The top end of the second swing rod 42 is connected to the first swing rod 41 . When the first swing rod 41 slides along the waist groove 1011 , the top end of the second swing rod 42 swings accordingly, thereby driving the movable contact piece 2 to swing.

[0051] In this embodiment, a second through hole 412 is opened in the middle of the first swing rod 41 , and two arc-shaped holding plates 413 are symmetrically arranged outside the second through hole 412 . The top end of the second swing rod 42 passes through the second through hole 412 , and the two arc-shaped holding plates 413 hold the second swing rod 42 .

[0052] The first swing rod 41 in this embodiment is an important component of the driving member 4, and a second through hole 412 is opened in the middle thereof. The second through hole 412 is a hole passing through the first swing rod 41, and is used to allow the top end of the second swing rod 42 to pass through and be embraced by the arc-shaped holding plate 413. The size and shape of the second through hole 412 are designed according to the diameter of the second swing rod 42 and the required connection method, so as to ensure that the top end of the second swing rod 42 can smoothly pass through the second through hole 412 and achieve a stable connection with the arc-shaped holding plate 413. Two arc-shaped holding plates 413 are symmetrically arranged outside the second through hole 412. The arc-shaped holding plates 413 are components of the first swing rod 41, and are designed to fix and hold the second swing rod 42 and apply a driving force to the second swing rod 42. The arc-shaped holding plates 413 are arc-shaped, so as to form a good match with the second swing rod 42. The two arc-shaped holding plates 413 hold the second swing rod 42, specifically, after the top of the second swing rod 42 passes through the second through hole 412, the two arc-shaped holding plates 413 hold the second swing rod 42 from both sides. The connection between the arc-shaped holding plates 413 and the first swing rod 41 can be integrally formed, or can be achieved by welding, riveting or other mechanical connection methods.

[0053] In this embodiment, a common-end conductive sheet 5, a left static contact sheet 6 and a right static contact sheet 7 are further provided in the bottom shell 102. The left static contact sheet 6 and the right static contact sheet 7 are arranged at intervals on the left and right. One end of the common-end conductive sheet 5 abuts against the middle position of the bottom of the moving contact sheet 2, and the other end of the common-end conductive sheet 5 is connected to the common-end wiring terminal 8. The moving contact sheet 2 is located between the left static contact sheet 6 and the right static contact sheet 7. The left static contact sheet 6 is connected to the left wiring terminal 9, and the right static contact sheet 7 is connected to the right wiring terminal 10. The moving contact sheet 2 swings to contact or separate from the left static contact sheet 6 and the right static contact sheet 7 to realize the conduction or disconnection of the switch circuit.

[0054] The bottom shell 102 in this embodiment is a component of the housing 1, and a common-end conductive sheet 5, a left static contact sheet 6 and a right static contact sheet 7 are arranged inside the bottom shell 102, and these components together constitute the key part of the switch circuit. The left static contact sheet 6 and the right static contact sheet 7 are arranged at intervals on the left and right sides of the bottom shell 102, and they are respectively located on both sides of the moving contact sheet 2. The left static contact sheet 6 and the right static contact sheet 7 can be fixed on the bottom shell 102 by welding, riveting or other mechanical connection methods. One end of the common-end conductive sheet 5 abuts against the middle position of the bottom of the moving contact sheet 2, and the other end is connected to the common-end wiring terminal 8. The common-end conductive sheet 5 can be a flat conductive material, and its shape and size are designed according to the swing range of the moving contact sheet 2 and the required current carrying capacity. The common-end conductive sheet 5 always abuts against the moving contact sheet 2 and maintains a contact state. The left static contact sheet 6 is connected to the left wiring terminal 9, and the right static contact sheet 7 is connected to the right wiring terminal 10. These connections can be achieved by welding, plugging or other electrical connection methods to ensure the conductivity and reliability of the circuit.

[0055] The swing of the moving contact piece 2 makes it contact or separate with the left stationary contact piece 6 and the right stationary contact piece 7, thereby realizing the conduction or disconnection of the switch circuit. When the moving contact piece 2 contacts the left stationary contact piece 6, the circuit is connected through the left wiring terminal 9; when the moving contact piece 2 contacts the right stationary contact piece 7, the circuit is connected through the right wiring terminal 10; when the moving contact piece 2 separates from both the left stationary contact piece 6 and the right stationary contact piece 7, the circuit is disconnected. The contact design of the moving contact piece 2 with the left stationary contact piece 6 and the right stationary contact piece 7 enables the switch to achieve multi-point contact, thereby improving the conductive performance and service life of the switch.

[0056] In this embodiment, the switch also includes a mounting bracket 11 and a mounting iron plate 12.
