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

[0034] The first swing lever 41 is slidingly installed in the shell 1, and is obliquely slid in the driving process, similar to the movement track of a pirate ship, the shaft center changes with the driving direction and is not oriented to flip, one end of the first swing lever 41 abuts against the key lever 3, and the other end cooperates with the second swing lever 42, the second swing lever 42 is swingingly installed in the shell 1, and is oriented to flip in the driving process, the shaft center does not change in the original position, one end of the second swing lever 42 cooperates with the first swing lever 41, and the other end is connected with the movable contact 2, the key lever 3 is provided with pressing points on the outer surfaces of two ends, when a user presses the pressing point of one end of the key lever 3, one end of the key lever 3 is driven to slide obliquely to the side without force after being pressed, thereby driving the second swing lever 42 to swing, the swing of the second swing lever 42 drives the movable contact 2 to swing in the shell 1 through the connection relationship between the second swing lever 42 and the movable contact 2, so that the circuit is turned on or turned off, since the first swing lever 41 is obliquely slid after being driven by the driving force of one end of the key lever 3, the horizontal component force of the first swing lever 41 applied to the second swing lever 42 can drive the second swing lever 42 to swing greatly, therefore, the key lever 3 only needs to swing a small angular motion stroke of 2° to make the second swing lever 42 swing a stroke of 5°, so that the circuit is turned on and turned off, the motion stroke of the key lever 3 is reduced, thereby reducing the thickness of the switch product protruding from the wall, improving the product appearance, and when used, the user only needs to press slightly to realize the turning on and turning off of the circuit, avoiding the key lever 3 from being stuck and stopped due to the large force pressing, and meanwhile, avoiding the key lever 3 from producing harsh noise due to the impact after being pressed with large force.

[0035] The utility model not only realizes the compact structure and the thinness of the switch product, but also improves the driving efficiency and the operation feeling through the optimized design of the driving part 4, and meets the demand of the modern electronic equipment on the ultra-thin switch.

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

[0037] In the embodiment, the shell 1 includes an upper cover 101 and a bottom shell 102, and the upper cover 101 is detachably installed with the bottom shell 102.

[0038] As Figure 3As shown, the upper cover 101 is designed with a groove structure, and the bottom shell 102 is designed with a snap-on structure. The snap-on structure and the groove structure snap together. Of course, it is also possible to design a snap-on structure on the upper cover 101 and a groove structure on the upper cover 101. The shape and size of the snap-on structure and the groove structure match to ensure that the upper cover 101 can accurately snap together with the bottom shell 102. Snap-on process: When assembling the housing 1, first place the upper cover 101 on top of the bottom shell 102 so that the snap-on structure and the groove structure are aligned. Then, gradually press along the edge of the bottom shell 102 so that the snap-on structure gradually embeds into the groove structure until the four edges of the bottom shell 102 are completely snapped together 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 bottom shell 102 of the housing 1 not only achieve quick and accurate snap-fit ​​installation, but also have good sealing and strength, providing stable and safe protection for the internal movable 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 rocker arm 41 is slidably mounted on the upper cover 101, the second rocker arm 42 is swingably mounted on the upper cover 101, the key rocker 3 is swingably mounted above the upper cover 101, the first rocker arm 41 is in contact with the upper cover 101, the top of the second rocker arm 42 is connected to the first rocker arm 41, the bottom of the second rocker arm 42 is in contact with the upper surface of the movable contact piece 2, and the movable contact piece 2 is swingably mounted in the bottom shell 102.

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

[0043] In this embodiment, the upper cover 101 is a component of the housing 1. Its two side walls are defined by oblique grooves 1011, which allow the first rocker arm 41 to slide within them, thereby translating the pressing action of the key rocker 3 into the driving action of the second rocker arm 42 and the movable contact piece 2. The grooves 1011 are formed on both sides of the upper cover 101 and are obliquely shaped to facilitate the sliding of the first rocker arm 41. The slope and dimensions of the grooves 1011 are determined by the range of movement of the first rocker arm 41 and the required driving force. A slide post 411 is provided at the position of the first rocker arm 41 corresponding to the groove 1011. The slide post 411 is a component of the first rocker arm 41, and its shape and dimensions match the groove 1011 to ensure smooth sliding within the groove 1011. The slide post 411 is slidably mounted within the groove 1011, and installation can be achieved by direct insertion. The sliding surface of the slide post 411 can be designed to reduce friction during sliding and improve sliding efficiency. The two ends of the first rocker arm 41 abut against the key rocker 3. In this embodiment, the abutment is through direct contact. When one end of the key rocker 3 is pressed, the key rocker 3 swings 2°. The force first acts on one end of the first rocker arm 41, which then slides along the waist groove 1011, driving the second rocker arm 42 connected to the first rocker arm 41 to swing 5°. The second rocker arm 42 drives the movable contact piece 2 to swing into or out of contact with the stationary contact piece, thereby turning the switch circuit on or off.

[0044] Through the above-mentioned structural design, the key rocker 3 exposed on the wall after installation has only a movement stroke 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 5°, so the appearance thickness is 10mm. The ultra-thin switch with a small angle drive in this embodiment not only achieves a compact structure and a thinner 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 part 4, meeting the demand 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 provided on the outside of the first through hole 1012. The second rocker arm 42 passes through the first through hole 1012 and is swingably mounted on the first mounting seat 1013. The top of the second rocker arm 42 is connected to the first rocker arm 41, and the bottom of the second rocker arm 42 is in contact with the moving contact piece 2.

[0046] The second swing lever 42 is a directional flip switch when driven, and the shaft center does not change in the original position. The bottom of the second swing lever 42 abuts against the upper surface of the movable contact 2. Specifically, the abutting portion is arranged at the bottom of the second swing lever 42, and the upper surface of the two ends of the movable contact 2 is designed to have a power contact. When the abutting portion contacts one side of the power contact, the side is in a power-on state. The movable contact 2 is swingingly installed in the bottom shell 102. Specifically, two swing clamping blocks are symmetrically arranged on the two side walls of the middle part of the movable contact 2, and the two swing clamping blocks are coaxially arranged. The bottom shell 102 is provided with two swing clamping grooves, and the two swing clamping blocks are respectively inserted into the two swing clamping grooves. The movable contact 2 is swingingly installed in the bottom shell 102 through the swing clamping blocks and the swing clamping grooves.

[0047] The size and shape of the first through hole 1012 are designed according to the diameter and swing range of the second swing lever 42, so as to ensure that the second swing lever 42 can freely swing in the first through hole 1012, so that the abutting portion of the second swing lever 42 can contact the power contact at the two ends of the movable contact 2.

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

[0049] The second swing lever 42 is swingingly installed on the first mounting seat 1013 through the first through hole 1012. One end of the second swing lever 42 extends out of the first through hole 1012 and is installed in the first mounting seat 1013, and the other end passes through the first through hole 1012 and abuts against the movable contact 2. The swing of the second swing lever 42 can be achieved by designing a swing pin on the side wall of the second swing lever 42, and a pin hole is arranged 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 lever 42 is connected with the first swing lever 41. When the first swing lever 41 slides along the waist groove 1011, the top end of the second swing lever 42 swings, thereby driving the movable contact 2 to swing.

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

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

[0053] In this embodiment, the bottom shell 102 is also provided with a common end conductive sheet 5, a left static contact sheet 6 and a right static contact sheet 7. The left static contact sheet 6 and the right static contact sheet 7 are arranged left and right. One end of the common end conductive sheet 5 abuts against the middle position of the bottom of the moving contact 2, and the other end of the common end conductive sheet 5 is connected to the common end terminal 8. The moving contact 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 terminal 9, and the right static contact sheet 7 is connected to the right terminal 10. The moving contact 2 swings to make contact with or separate from the left static contact sheet 6 and the right static contact sheet 7 to realize the conduction or disconnection of the switching circuit.

[0054] The bottom shell 102 in this embodiment is a component of the housing 1, and the inside of the bottom shell 102 is provided with a common end conductive sheet 5, a left static contact sheet 6 and a right static contact sheet 7. These components jointly constitute a key part of the switching circuit. The left static contact sheet 6 and the right static contact sheet 7 are arranged left and right in the bottom shell 102, and they are respectively located on both sides of the moving contact 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 2, and the other end of the common end conductive sheet 5 is connected to the common end 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 2 and the required current carrying capacity. The common end conductive sheet 5 always abuts against the moving contact 2 and maintains the contact state. The left static contact sheet 6 is connected to the left terminal 9, and the right static contact sheet 7 is connected to the right terminal 10. These connections can be achieved by welding, plugging or other electrical connection methods to ensure the conduction and reliability of the circuit.

[0055] The swinging motion of the movable contact 2 causes it to contact or separate with the left and right stationary contacts 6 and 7, thereby connecting or disconnecting the switch circuit. When the movable contact 2 contacts the left stationary contact 6, the circuit is connected through the left terminal 9; when the movable contact 2 contacts the right stationary contact 7, the circuit is connected through the right terminal 10. When the movable contact 2 separates from both the left and right stationary contacts 6 and 7, the circuit is disconnected. The contact design of the movable contact 2, the left and right stationary contacts 6 and 7 enables the switch to achieve multiple points of contact, improving the switch's conductivity and service life.

[0056] In this embodiment, the switch also includes a mounting bracket 11 and a mounting iron plate 12. The mounting iron plate 12 is snap-fitted and installed on the bottom of the mounting bracket 11. The button rocker 3 is swing-fitted and installed on the top of the mounting bracket 11.
