Description

Technical Field

[0001] This invention relates to the field of electrical devices, and in particular to a switch. Background Technology

[0002] A rocker switch, as a typical type of switch, includes: a rocker with a moving contact, a transition piece connected to a pin assembly, and a panel that abuts against the transition piece. The user presses the panel to drive the transition piece to rotate, which in turn causes the pin assembly to move the rocker, causing the moving contact to contact or separate from the stationary contact, thereby achieving the purpose of turning the switch on or off.

[0003] However, on the one hand, since the pivot of the panel is the same as the pivot of the transition piece, the rotation angle of the panel needs to be large enough to allow the pin assembly to move the rocker into place, which increases the thickness of the switch. On the other hand, the structure and layout of the components in the rocker switch limit the thickness of the switch to be designed to be sufficiently large. Summary of the Invention

[0004] In view of this, the present invention provides a switch that can solve the above-mentioned technical problems.

[0005] Specifically, the following technical solutions are included:

[0006] A switch, the switch comprising: a panel, a base, a travel amplification component, a moving contact component, and a stationary contact component;

[0022] The two levers partially overlap along the second direction, such that the first side and the second side of the levers are located on both sides of the terminal block, respectively.

[0023] The second direction is perpendicular to the first direction in the same horizontal plane.

[0024] In some possible implementations, the side of the transition member is provided with a first pin, and the corresponding position of the lever member is provided with a first shaft hole;

[0025] The first shaft hole is configured to receive the first pin and allow the transition member and the lever member to rotate relative to the base about their respective axes of rotation.

[0026] In some possible implementations, the first shaft hole is an oblong hole.

[0027] In some possible implementations, the switch further includes a oscillating positioning element connected between the travel amplification component and the base, the oscillating positioning element being configured to enhance the positioning of the travel amplification component and the panel in closed and open positions.

[0028] In some possible implementations, the swing positioning element is a momentary spring, with a first end connected to the side of the base and a second end connected to the side of the transition element.

[0029] In some possible implementations, the transition element includes: a transition element body and two connecting blocks, the connecting blocks having a first pin for hinged connection with the lever element;

[0037] In some possible implementations, the base includes a seat and a cover, the seat having a receiving cavity to accommodate the moving contact assembly and the stationary contact assembly;

[0038] The cover is detachably connected to the base and covers the upper port of the accommodating cavity. The cover is also used to hinge with the stroke amplification component.

[0039] The drive unit penetrates the cover and extends into the accommodating cavity to interact with the spring sheet.

[0044] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0045] The switch provided in this embodiment of the invention has at least the following improvements compared to a traditional rocker switch:

[0046] Firstly, an improved moving contact assembly is used, in which the terminal block is fixed to the middle of the spring piece, and the moving contact is fixed to the end of the spring piece. The driving part presses against the part of the spring piece located between the terminal block and the moving contact to make it elastically deformed, thereby realizing the position change of the moving contact, so that the moving contact contacts or separates from the stationary contact.

[0047] Compared to rocker switches where the transition element drives the rocker to swing and change the position of the moving contact, the moving contact assembly provided in this embodiment of the invention allows for smaller longitudinal dimensions (i.e., thickness) of both the transition element and the spring, which significantly reduces the switch thickness and enables the fabrication of ultra-thin switches. Furthermore, since the terminal connection section is fixedly connected to the spring, the terminal remains electrically connected to the moving contact throughout the change in position, eliminating the arcing problem caused by rocker rocker movement.

[0048] Secondly, a stroke amplification component is used. This component is fixedly connected to the panel and hinged to the base. The panel drives the stroke amplification component to rotate relative to the base. The rotating component, through its drive unit, acts on the corresponding position of the spring, deforming it and causing the moving contact to contact or separate from the stationary contact. During this process, the travel of the drive unit is greater than the rotation travel of the panel; that is, the panel achieves a larger travel of the drive unit with a smaller rotation angle. This not only effectively controls the contact or separation between the moving and stationary contacts, ensuring the reliability of the switch's on / off operation, but also facilitates the development of ultra-thin switches.

[0083] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0084] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0085] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0086] In this invention, directional terms such as "upper," "lower," and "side" are generally based on the assembly state of the switch. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute locations. Specifically, the location of the switch panel is referred to as "upper" or "top," and the location of the switch base is referred to as "lower" or "bottom." The thickness of each component in this invention is considered to be the dimension along the vertical direction (i.e., longitudinal direction).

[0087] Rocker switches are a common type of switch, consisting of a rocker with a moving contact, a transition piece connected to a pin assembly, and a panel that abuts against the transition piece. The user presses the panel to rotate the transition piece, which in turn moves the rocker with the pin assembly, causing the moving contact to make or separate from the stationary contact.

[0088] However, on the one hand, since the pivot of the panel is the same as the pivot of the transition piece, the rotation angle of the panel needs to be large enough to allow the pin assembly to move the rocker into place, which increases the thickness of the switch. On the other hand, the structure and layout of the components in the rocker switch limit the thickness of the switch to be designed to be sufficiently large.

[0089] To address the aforementioned technical problems, embodiments of the present invention provide a switch, as shown in the attached figure. Figure 1 , Figure 2 and Figure 3 As shown, the switch includes: a panel 1, a base 2, a travel amplification assembly 3, a moving contact assembly 5, and a stationary contact assembly 6. (See attached diagram.) Figure 5 As shown, the moving contact assembly 5 includes: a spring 51, a terminal 52 connected and fixed to the middle of the spring 51, and a moving contact 53 connected and fixed to the end of the spring 51; both the moving contact assembly 5 and the stationary contact assembly 6 are located inside the base 2, and the moving contact 53 corresponds to the stationary contact 60 on the stationary contact assembly 6.

[0090] The stroke amplification component 3 is fixedly connected to the panel 1 and hinged to the base 2. The stroke amplification component 3 has a drive part 321. The stroke amplification component 3 is configured to be pressed by the panel 1 to deform the corresponding position of the spring piece 51 by the drive part 321, thereby causing the moving contact 53 to contact or separate from the corresponding stationary contact 60, and to amplify the rotation stroke of the panel 1.

[0091] The switch provided in this embodiment of the invention has at least the following improvements compared to a traditional rocker switch:

[0092] Firstly, an improved moving contact assembly 5 is used, wherein the terminal 52 is fixed to the middle of the spring piece 51, and the moving contact 53 is fixed to the end of the spring piece 51. The driving part 321 presses the part of the spring piece 51 located between the terminal 52 and the moving contact 53 to make it elastically deform, thereby realizing the position change of the moving contact 53, so that the moving contact 53 contacts or separates from the stationary contact 60.

[0093] Compared to rocker switches where the transition element requires the rocker to swing to change the position of the moving contact, the operation of the moving contact assembly 5 provided in this embodiment of the invention allows for smaller longitudinal dimensions (i.e., thickness) of both the transition element 31 and the spring 51. This significantly reduces the thickness of the switch, enabling the fabrication of an ultra-thin switch. Furthermore, since the terminal connection section 511 is fixedly connected to the spring 51, the terminal 52 remains electrically connected to the moving contact 53 throughout the position change of the moving contact 53, preventing the arcing problem caused by rocker rocker bouncing.

[0094] Secondly, a stroke amplification component 3 is used. This component is fixedly connected to the panel 1 and hinged to the base 2. The panel 1 drives the stroke amplification component 3 to rotate relative to the base 2. The rotating component 3, through its driving part 321, acts on the corresponding position of the spring 51, causing it to deform. This, in turn, causes the moving contact 53 to contact or separate from the stationary contact 60. During this process, the stroke of the driving part 321 is greater than the rotation stroke of the panel 1; that is, the panel 1 achieves a larger stroke of the driving part 321 with a smaller rotation angle. This not only effectively controls the contact or separation between the moving contact 53 and the stationary contact 60, ensuring the reliability of the switch's on / off operation, but also facilitates the development of ultra-thin switches.

[0095] The following is an exemplary description of the structure, arrangement, and function of each component involved in the switch:

[0096] For moving contact assembly 5, see Appendix Figure 4 The example illustrates the structure of a spring clip 51, as shown in the attached figure. Figure 4 As shown, the spring 51 includes: a terminal connection section 511, one or two elastic sections 512, and one or two contact connection sections 513. The first ends of the two elastic sections 512 are each connected to the two opposite ends of the terminal connection section 511, so that the two elastic sections 512 are located on both sides of the terminal connection section 511.

[0097] The number of elastic segments 512 and contact connection segments 513 are the same and they correspond one-to-one. For example, when the switch is designed as a single-pole single-control switch, both elastic segments 512 and contact connection segments 513 can be set to one and located on one side of the terminal connection segment 511. Of course, it is also feasible to set two elastic segments 512 and two contact connection segments 513 and arrange them symmetrically on both sides of the terminal connection segment 511. In this case, a moving contact 53 can be set on only one of the contact connection segments 513. For example, when the switch is designed as a single-pole double-control switch, both elastic segments 512 and two contact connection segments 513 are set to two and arranged symmetrically on both sides of the terminal connection segment 511, and each contact connection segment 513 is provided with one moving contact 53.

[0098] In this configuration, the first end of the elastic segment 512 is connected to one end of the terminal connection segment 511, and the second end of the elastic segment 512 is connected to the corresponding contact connection segment 513. For example, when two elastic segments 512 and two contact connection segments 513 are provided, the first ends of the two elastic segments 512 are each connected to the opposite ends of the terminal connection segment 511, thereby placing the two elastic segments 512 on both sides of the terminal connection segment 511. The second ends of the two elastic segments 512 are each connected to the corresponding contact connection segment 513 to accommodate a two-way switch.

[0099] The terminal 52 is fixedly connected by the terminal connecting section 511 located in the middle of the spring 51, and the moving contact 53 is fixedly connected by the contact connecting sections 513 located at both ends of the spring 51. In this way, by pressing the elastic section 512 located between the terminal 52 and the moving contact 53, the elastic section 512 can undergo elastic deformation, thereby driving the position of the moving contact 53 to move.

[0100] For the spring 51, its elastic segment 512, terminal connection segment 511 and contact connection segment 513 can be connected in various ways, as long as the three have high and reliable connection strength. For example, this includes but is not limited to integral molding connection, welding, bonding and other connection methods.

[0101] The one-piece molding connection method has advantages such as high connection strength, strong structural stability, and simple manufacturing process. As an example, the spring sheet 51 provided in this embodiment of the invention is prepared by a one-piece molding process. For example, a highly elastic metal sheet can be used, and operations such as stamping, bending, and cutting can be performed to form a one-piece spring sheet 51. The metal sheet can be a copper sheet, which gives the spring sheet 51 excellent elasticity, electrical conductivity, and thermal conductivity.

[0102] The two elastic segments 512 of the spring piece 51 are located on both sides of the terminal connection segment 511. In this way, after the terminal connection segment 511 is connected to the terminal 52, the two elastic segments 512 are suspended relative to the terminal 52 to ensure good elasticity.

[0103] In some examples, there is an angle between the elastic segment 512 and the terminal connection segment 511, which ranges from 120° to 180°, for example, including but not limited to: 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc.

[0104] See Figure 4 When the included angle between the elastic segment 512 and the terminal connection segment 511 is 180°, both are arranged horizontally and located in the same horizontal plane. See [link / reference] Figure 6 When the included angle between the elastic segment 512 and the terminal connection segment 511 is less than 180° and greater than or equal to 120°, the elastic segment 512 is arranged at an angle relative to the terminal connection segment 511, and the elastic segment 512 is located above the terminal connection segment 511.

[0105] With this design, the elastic segment 512 is more easily driven to undergo elastic deformation, and at the same time, it can obtain a large elastic potential energy during deformation. This is beneficial to improving the action force of the moving contact 53 and is more conducive to avoiding arcing.

[0106] In some examples, both the contact connection segment 513 and the resilient segment 512 are arranged horizontally and are located in the same horizontal plane (not shown in the figure). For example, the terminal connection segment 511, the resilient segment 512, and the contact connection segment 513 are all located in the same horizontal plane.

[0107] In other examples, see Figure 5 The contact connection section 513 includes a guide section 5131 and a connecting contact section 5132 connected to each other. The guide section 5131 is arranged at an angle relative to the elastic section 512, such that the connecting contact section 5132 is located above or below the elastic section 512.

[0108] The guide section 5131 can be arranged at an angle downwards or upwards relative to the elastic section 512. By arranging the guide section 5131 at an angle, the connecting contact section 5132 is located above or below the elastic section 512. In this way, after the moving contact 53 is connected to the connecting contact section 5132, the moving contact 53 is located above or below the elastic section 512 accordingly, to adapt to different types of switches.

[0109] For example, for normally closed switches, combined with Figure 3 It can be seen that the moving contact 53 is located below the elastic segment 512. For a normally open switch, combined with... Figure 9 It can be seen that by positioning the moving contact 53 above the elastic segment 512, the above-mentioned orientation of the moving contact 53 can be adapted to different types of switches, ensuring that sufficient contact pressure is obtained between the moving contact 53 and the stationary contact 60.

[0110] In some examples, the connecting contact segment 5132 is arranged horizontally, so that the moving contact 53 is also arranged horizontally accordingly. When the stationary contact 60 in the switch is also arranged horizontally, the moving contact 53 and the stationary contact 60 can make complete ground-to-ground contact, increasing the contact area and obtaining a larger contact pressure.

[0111] The elastic segment 512 can be a strip with a uniform width or a strip with varying widths. The length direction of the spring piece 51 refers to the distribution direction from the contact connection segment 513 to the terminal connection segment 511; the width direction of the spring piece 51 refers to the direction that is perpendicular to its length direction and extends along the horizontal plane.

[0112] In some examples, the width of the elastic segment 512 is inconsistent, as shown in the attached figure. Figure 5As shown, the elastic segment 512 includes a first elastic segment 5121 and a second elastic segment 5122 connected to each other. The end of the first elastic segment 5121 away from the second elastic segment 5122 is connected to the terminal connection segment 511, and the end of the second elastic segment 5122 away from the first elastic segment 5121 is connected to the contact connection segment 513. From the terminal connection segment 511 to the second elastic segment 5122, the width of the first elastic segment 5121 gradually decreases, and the minimum width of the first elastic segment 5121 is equal to the width of the second elastic segment 5122.

[0113] By making the width of the first elastic segment 5121 longer near the terminal connection segment 511 and gradually decreasing in width away from the terminal connection segment 511, the fatigue resistance between the elastic segment 512 and the terminal connection segment 511 can be improved. This is because the position of the terminal connection segment 511 is fixed, while the elastic segment 512 frequently deforms and displaces relative to the terminal connection segment 511. Increasing the width at this position accommodates the frequent displacement of the elastic segment 512 and prevents irreversible hard deformation. By making the width of the second elastic segment 5122 equal to the minimum width of the first elastic segment 5121, the elastic deformation capacity of the second elastic segment 5122 is improved, giving it a higher deformation range.

[0114] For the terminal block 52, which is connected to the terminal connection section 511 of the spring contact 51, the connection methods between the two include, but are not limited to, welding, snap-fitting, riveting, etc. Among them, snap-fitting and riveting are easy to disassemble, which simplifies the assembly process of the terminal block 52 and facilitates maintenance or replacement. For example, the terminal block 52 is snap-fitted to the terminal connection section 511.

[0115] The structure of the moving contact 53 and its connection method with the contact connection section 513 can adopt conventional techniques in the field, and the embodiments of the present invention do not impose specific limitations on this.

[0116] According to its control method, the switch involved in the embodiments of the present invention can be a single-pole single-control switch or a single-pole double-control switch. When the switch is a single-pole single-control switch, the number of moving contacts 53 in the moving contact assembly 5 is designed to be one; when the switch is a single-pole double-control switch, the number of moving contacts 53 in the moving contact assembly 5 is designed to be two symmetrical contacts.

[0117] The stroke amplification component 3 can not only transmit the pressing force of the panel 1 to the spring 51, but also amplify the rotation stroke of the panel 1, so that the stroke of the spring 51 is greater than the rotation stroke of the panel 1. This can not only improve the reliability of the switch, but also facilitate the ultra-thin development of the panel 1.

[0118] In some examples, such as the attached Figure 2 Or attach Figure 8As shown, the stroke amplification assembly 3 includes: a transition member 31 and two lever members 32 arranged symmetrically; wherein, the transition member 31 is fixedly connected to the panel 1, and the two sides of the transition member 31 distributed along the first direction are respectively hinged to a lever member 32, and the middle part of the transition member 31 is hinged to the base 2.

[0119] The first direction mentioned above is the same as the distribution direction of the two pressing sides 10 of the panel 1. The lever 32 is not only hinged to the base 2, but also hinged to the base 2, and the drive part 321 is provided at the bottom of one side of the lever 32. In some examples, the drive part 321 is in the shape of a drive rib.

[0120] For the principle of amplifying the rotational stroke of the panel by lever 32, please refer to [link / reference needed]. Figure 7 It should be noted that, Figure 7 The positions of the fulcrums are shown for illustrative purposes only. In actual applications, the specific positions of the fulcrums may vary. For example, the fulcrums may not be as shown in the diagram. Figure 7 They are located on the same horizontal straight line as shown.

[0121] The hinge point between the transition member 31 and the lever member 32 is defined as the first fulcrum O1, the hinge point between the lever member 32 and the base 2 is defined as the second fulcrum O2, and the pressing fulcrum between the drive part 321 and the spring piece 51 is defined as the third fulcrum O3. The distance L2 between the second fulcrum O2 and the third fulcrum O3 is greater than the distance L1 between the second fulcrum O2 and the first fulcrum O1.

[0122] Understandably, the first fulcrum O1 is the center point of the connecting shaft and / or hole between the transition member 31 and the lever member 32, the second fulcrum O2 is the center point of the connecting shaft and / or hole between the lever member 32 and the base 2, and the third fulcrum O3 is the center point of the bottom of the drive part 321 that contacts the spring piece 51.

[0123] When in use, panel 1 drives transition member 31 to rotate, and transition member 31 drives lever member 32 to rotate through first fulcrum O1. The rotating lever member 32 drives the drive part 321 on it to move up and down.

[0124] For lever 32, it is connected to base 2, transition member 31, and drive unit 321. The stroke of the first fulcrum O1 in the vertical direction is defined as H1 (i.e., the movement stroke of the hinge point between transition member 31 and lever 32), and the stroke of the third fulcrum O3 in the vertical direction is defined as H2 (i.e., the movement stroke of drive unit 321). See attached... Figure 7 As shown, based on the lever amplification principle, we know that H2 / L2=H1 / L1, that is, H2=H1×(L2 / L1). Since L2 is greater than L1, then H2 must be greater than H1.

[0125] In summary, by making the distance L2 between the second fulcrum O2 and the third fulcrum O3 greater than the distance L1 between the second fulcrum O2 and the first fulcrum O1, the travel distance of the drive unit 321 is greater than the travel distance of the transition member 31. Since the transition member 31 is fixedly connected to the panel 1 and their travel distances are consistent, the travel distance of the drive unit 321 is greater than the travel distance of the panel 1. This allows the relatively small rotational travel distance of the panel 1 to be amplified to any travel distance of the drive unit 321, ensuring that the travel distance of the drive unit 321 can effectively control the on / off state of the switch.

[0126] The arrangement of the transition member 31 in the switch is determined according to the panel 1, while the specific arrangement of the lever member 32 in the switch can take various forms, as long as the distance L2 between the second fulcrum O2 and the third fulcrum O3 is greater than the distance L1 between the second fulcrum O2 and the first fulcrum O1. The following are exemplary descriptions of switches that meet the above conditions:

[0127] In some implementations (1), as shown in the appendix Figure 2 or Figure 10 As shown, the second fulcrum O2 and the third fulcrum O3 are located on the first side and the second side of the lever 32, respectively, distributed along the first direction. The first fulcrum O1 is located between the first side and the second side of the lever 32. That is, the second fulcrum O2, which connects to the base 2, and the third fulcrum O3, where the drive part 321 is located, are located on the first side and the second side of the lever 32, respectively. Therefore, the first fulcrum O1, which connects to the transition member 31, is located between the first side and the second side of the lever 32. The distribution direction of the first side and the second side of the lever 32 is the same as the distribution direction of the two pressing sides 10 on the panel 1.

[0128] For example, the first fulcrum O1 of the lever 32 that connects to the transition member 31 is located in the middle of the lever 32 or on the first side close to the lever 32.

[0129] For the above implementation method (1), the lever component 32 includes at least the following two configuration methods:

[0130] In some examples (1.1), as shown in the appendix Figure 2 As shown, the spring 51 includes two elastic segments 512, which are located on both sides of the terminal 52. Taking the terminal 52 in the moving contact assembly 5 as the boundary, two levers 32 are symmetrically arranged on both sides of the terminal 52, and the levers 32 act on the corresponding elastic segments 512 through the driving part 321.

[0131] As attached Figure 2As shown, one lever 32 is located entirely in the space to the right of the terminal 52, and the other lever 32 is located entirely in the space to the left of the terminal 52. The driving part 321 on the right lever 32 acts on the elastic segment 512 on the right side of the terminal 52, and the driving part 321 on the left lever 32 acts on the elastic segment 512 on the left side of the terminal 52.

[0132] In some examples (1.2), as shown in the appendix Figure 10 As shown, the spring 51 includes two elastic segments 512, which are located on both sides of the terminal 52. Taking the terminal 52 in the moving contact assembly 5 as the boundary, the two levers 32 partially overlap along the second direction, such that the first side and the second side of the lever 32 are located on both sides of the terminal 52, respectively; wherein, the second direction is perpendicular to the first direction in the same horizontal plane.

[0133] In other words, for one of the lever members 32, the first side of the lever member 32 (hinged to the base 2) is located in the space to the right of the terminal, while the second side of the lever member 32 (the side where the drive part 321 is located) is located in the space to the left of the terminal, such that the drive part 321 thereon interacts with the elastic segment 512 on the left. Correspondingly, the first side of the other lever member 32 (hinged to the base 2) is located in the space to the left of the terminal, while the second side of the lever member 32 (the side where the drive part 321 is located) is located in the space to the right of the terminal, such that the drive part 321 thereon interacts with the elastic segment 512 on the right.

[0134] In this example (1.2), the two levers 32 will inevitably overlap in the second direction. In order to prevent the two levers 32 from interfering with each other and the levers 32 from interfering with the transition piece 31, and to ensure that the driving part 321 on each of the two levers 32 acts at the middle position of the corresponding elastic segment 512, anti-interference grooves or anti-interference cavities can be arranged on each of the two levers 32. At the same time, the design of anti-interference grooves or anti-interference cavities also helps to reduce the space occupied by the levers 32 inside the switch.

[0135] In this example (1.2), the first fulcrum O1 of the lever 32 connected to the transition member 31 is close to the first side of the lever 32, that is, the first fulcrum O1 and the second fulcrum O2 of the lever 32 are located on the same side of the terminal 52.

[0136] In some implementations (2), as shown in the appendix Figure 11As shown, the first fulcrum O1 and the third fulcrum O3 are located on the first side and the second side of the lever 32 along the first direction, respectively, and the second fulcrum O2 is located between the first side and the second side of the lever 32. That is, the first fulcrum O1 of the lever 32, which is connected to the transition member 31, and the third fulcrum O3, where the driving part 321 is located, are located on the first side and the second side of the lever 32, respectively. Therefore, the second fulcrum O2 of the lever 32, which is connected to the base 2, is located between the first side and the second side of the lever 32.

[0137] The spring 51 includes two elastic segments 512, which are located on both sides of the terminal 52; with the terminal 52 in the moving contact assembly 5 as the boundary, the two levers 32 partially overlap along the second direction, such that the first side and the second side of the levers 32 are located on both sides of the terminal 52 respectively; wherein, the second direction is perpendicular to the first direction in the same horizontal plane.

[0138] For example, the first fulcrum O1 of the lever 32 connected to the transition member 31 and the second fulcrum O2 of the lever 32 connected to the base 2 are located on the same side of the terminal 52, while the drive part 321 on it is located on the other side of the terminal 52. It is sufficient that the distance L2 between the second fulcrum O2 and the third fulcrum O3 is greater than the distance L1 between the second fulcrum O2 and the first fulcrum O1.

[0139] For the lever 32 involved in the above examples, the hinge method between it and the transition member 31, the hinge method between it and the base 2, and the structure of the drive part 321 provided on it can all be the same. The only difference is that the main structure of the lever 32 is slightly different. However, considering that the differences between the main structures of these lever 32 can be obtained through adaptive adjustment, the main structure of the other lever 32 can be known when determining the main structure of one type of lever 32.

[0140] The following description uses the structure of lever 32 in example (1.1) as an example:

[0141] As attached Figure 2 and combined Figure 12 and Figure 13 As shown, the lever 32 includes a lever body 322 and a drive part 321, wherein the drive part 321 is connected to the second side of the lever body 322 and the drive part 321 is located below the lever body 322.

[0142] The first side of the lever body 322 is hinged to the base 2. For example, the first side of the lever body 322 has a second shaft hole 3224. The axial direction of the second shaft hole 3224 is along the second direction. Correspondingly, a second pin 201 is provided on one side of the base 2. The second pin 201 is adapted to the second shaft hole 3224, so that the lever body 322 can rotate relative to the base 2.

[0143] In some examples, such as the attached Figure 13 As shown, the lever body 322 is provided with a relief groove 3222, which is used to accommodate the swing positioning member 4 in the form of a momentary spring. Thus, a second shaft hole 3224 is provided on each of the side plates of the lever body 322 located on both sides of the relief groove 3222 distributed along the second direction.

[0144] A first shaft hole 3221 is provided at a position corresponding to the side of the transition piece 31 on the lever body 322, so as to be movably connected with the first pin 3101 on the side of the transition piece 31, so that both the lever piece 32 and the base 2 can rotate.

[0145] In some examples, such as the attached Figure 13 As shown, the lever body 322 is provided with an assembly groove 3223, which is used to accommodate the side of the transition member 31, for example, to accommodate the connecting block 312 of the transition member 31 described below. In this way, each of the side plates of the lever body 322 located on both sides of the assembly groove 3223 is provided with a first shaft hole 3221, which not only facilitates the hinge arrangement between the transition member 31 and the lever body 322, but also helps to make the internal structure of the switch more compact.

[0146] In some examples, such as the attached Figure 13 As shown, the clearance groove 3222 and the assembly groove 3223 are distributed sequentially along the first direction and are connected to each other to simplify the molding difficulty of the lever body 322. In order to improve the assembly efficiency of the lever 32 and reduce its weight, the bottom of the clearance groove 3222 is open (i.e., the clearance groove 3222 has no bottom wall), and the bottom of the part of the assembly groove 3223 corresponding to the first shaft hole 3221 is designed to be open, while the remaining part of the assembly groove 3223 is designed to be closed (i.e., the remaining part of the assembly groove 3223 has a bottom wall) so as to achieve a reliable connection with the drive unit 321.

[0147] In the embodiments of the present invention, as shown in the appendix Figure 13 As shown, a first pin 3101 is provided on the side of the transition member 31, and a first shaft hole 3221 is provided at the corresponding position of the lever member 32; the first shaft hole 3221 is used to accommodate the first pin 3101 and allows the transition member 31 and the lever member 32 to rotate relative to the base 2 about their respective axes.

[0148] Understandably, the transition piece 31 and the lever piece 32 each rotate around their hinge points with the base 2. That is, the rotational positions of the transition piece 31 and the lever piece 32 relative to the base 2 are determined accordingly, and the rotational trajectories of the transition piece 31 and the lever piece 32 are determined.

[0149] Under the premise of ensuring that the transition member 31 can effectively drive the lever member 32, in order to prevent the transition member 31 and the lever member 32 from interfering with each other's rotation, when the transition member 31 and the lever member 32 are rotatably connected through the first pin 3101 and the first shaft hole 3221, the first shaft hole 3221 is designed to correct the above interference, so that the transition member 31 and the lever member 32 can each rotate around their predetermined rotation trajectory.

[0150] The first shaft hole 3221 cooperates with the first pin 3101 to transmit the rotation of the transition member 31 to the lever member 32, so that the lever member 32 rotates passively. In other words, the inner wall of the first shaft hole 3221 can abut against the outer wall of the first pin 3102 to realize the drive of the transition member 31 to the lever member 32.

[0151] The first shaft hole 3221 can be designed as a non-circular hole, such as a near-circular non-circular hole, an ellipse, or an oblong hole. For example, the first shaft hole 3221 can be an oblong hole, which not only solves the above-mentioned technical problems but also facilitates precise forming and manufacturing.

[0152] In the embodiments of the present invention, the switch, transition member 31, and lever member 32 work together, and their positional changes can stabilize them in a closed position and an open position. The closed position corresponds to the closed state of the switch, and the open position corresponds to the open state of the switch.

[0153] In some implementations, the switch involved in the embodiments of the present invention further includes a swing positioning member 4, which is connected between the stroke amplification component 3 and the base 2. The swing positioning member 4 is configured to enhance the positioning of the stroke amplification component 3 and the panel 1 in the closed position and the open position.

[0154] The rocker switch has two sets of swing positioning components arranged symmetrically. One set of swing positioning components 4 is located below the upward side of the panel, and the other set of swing positioning components 4 is located below the downward side of the panel.

[0155] By further configuring the swing positioning component 4, the stroke amplification component 3 can be stabilized in the closed and open positions under the action of the swing positioning component 4. This can help enhance the positioning of the panel 1 and the transition component 31 in the closed and open positions. In addition, it can also promote the rapid switching of the panel 1 and the transition component 31 between the closed and open positions, which is beneficial to improving the dialing feel of the switch and enhancing the user experience.

[0156] When the switch is in the normally closed or normally open state, one of the swing positioning members 4 has an upward pulling force on one side of the transition member 31, and the other swing positioning member 4 has a downward pulling force on the other side of the transition member 31. When there is no external force, the upward pulling force and the downward pulling force are balanced, so that the positions of the swing positioning member 4 and the transition member 31 are fixed. When the position of the transition member 31 is fixed, the positions of the panel 1 and the lever member 32 are also fixed accordingly.

[0157] The swing positioning member 4 can be designed in various structural types, as long as it meets the following conditions: it can change its position accordingly with the rotation of the transition member 31 to adapt to the position change of the transition member 31, and it can reach a stable state at two extreme positions to achieve self-fixation, thereby positioning the position of the transition member 31. This self-fixation can only be released by an external force of a certain magnitude.

[0158] Understandably, the stable contact state and stable separation state between the moving contact 53 and the stationary contact 60 are controlled by the two stable states of the swing positioning element 4, thereby achieving the purpose of switching on and off.

[0159] Examples of swing positioning elements 4 that meet the above requirements include, but are not limited to: instantaneous springs, cooperating linkage mechanisms + springs, etc. Considering the miniaturization requirements of the switch, in some examples, the swing positioning element 4 is an instantaneous spring (see...). Figures 12-13 The instantaneous spring, used as the swing positioning component 4, not only fixes the transition component 31 at its extreme positions but also adapts to the lateral layout of the internal components of the switch, facilitating the ultra-thin development of the switch. Furthermore, the instantaneous spring's characteristic of generating instantaneous motion upon being subjected to external force not only improves the speed at which the moving contact 53 and the stationary contact 60 contact or separate but also enhances the tactile feedback when the user presses the panel 1.

[0160] In this embodiment of the invention, the elastic force of the instantaneous spring is much greater than that of the spring plate 51, so that the position of the transition piece 31 and the spring plate 51 can be fixed by the instantaneous spring alone.

[0161] See Figure 12 When the swing positioning component 4 is a momentary spring, the first end of the swing positioning component 4 is connected to the side of the base 2, and the second end of the swing positioning component 4 is connected to the side of the transition component 31. The connection between the swing positioning component 4 and the base 2, and between the swing positioning component 4 and the transition component 31, is a fixed connection and / or a movable connection.

[0162] Taking movable connections as an example, they include, but are not limited to, bushing connections, hook and loop connections, etc. For example, the swing positioning part 4 can be connected to the base 2 and the transition part 31 by a bushing connection.

[0163] In some examples, as shown in the appendix Figure 3 Or attach Figure 9 As shown, the sides of the base 2 and the transition piece 31 are each provided with protruding posts, so that the protruding posts are sleeved in the two end ports of the swing positioning piece 4 (i.e., the instantaneous spring) to realize the above-mentioned bushing connection.

[0164] In this manner, the swing positioning component 4 (i.e., the instantaneous spring) is more adaptable to the rotation process of the transition component 31, making the pressing operation of the panel 1 smoother.

[0165] During the switching process of the normally open or normally closed contact of the switch, both the swing positioning member 4 and the transition member 31 are in an unstable state. At this time, the swing positioning members 4 (i.e., instantaneous springs) located on both sides of the transition member 31 can be in a horizontal state. That is, the central axis of the two protrusions on the side of the base 2 and the side of the transition member 31 coincides. At this time, both ends of the swing positioning member 4 are squeezed, causing the swing positioning member 4 to deform and become unstable.

[0166] For transition piece 31, as shown in the appendix Figure 12 As shown, the transition member 31 includes: a transition member body 311 and two connecting blocks 312. The two connecting blocks 312 are located on opposite sides of the transition member body 311 along a first direction. Each connecting block 312 has a first pin 3101 for hinged connection with the lever member 32. The connecting blocks 312 and the transition member body 311 are located in the same horizontal plane (see [reference]). Figure 12 Alternatively, the connecting block 312 is located on the side of the transition body 311 facing the spring piece 51 (i.e., the connecting block 312 is located below the transition body 311, not shown in the figure, but can be referenced). Figure 10 and Figure 11 (and are aware of the structural layout).

[0167] As can be seen, the position of the connecting block 312 can be adjusted accordingly in the vertical direction. The following provides illustrative examples of the two arrangements of the connecting block 312:

[0168] In some examples, as shown in the appendix Figure 12 As shown, the connecting block 312 and the transition body 311 are located in the same horizontal plane. In this example, the side of the connecting block 312 closer to the transition body 311 can be used to fix it to the panel 1, while the first pin 3101 is provided on the other side of the connecting block 312 away from the transition body 311.

[0169] The first pin 3101 is hinged to the first shaft hole 3221 on the lever 32, as shown in some examples. Figure 13 A protruding post is provided at the middle position of the outermost part of the connecting block 312 to connect with the swing positioning component 4 shaft sleeve.

[0170] Furthermore, in order to reduce the size of the switch, the outermost part of the connecting block 312 has a groove, and the protrusion is disposed in the groove to increase the length of the instantaneous spring without increasing the size of the switch.

[0171] Furthermore, based on the above example, the transition body 311 and the connecting block 312 can be flat plate structures of different sizes, such as rectangular plates, wherein the dimension of the connecting block 312 along the second direction is smaller than the dimension of the transition body 311 in that direction, so as to compact the internal structure of the switch.

[0172] The side of the connecting block 312 closest to the transition body 311 is fixedly connected to the panel 1. For example, the connection methods between the two include, but are not limited to: snap-fit, riveting, welding, bonding, integral molding connection, etc.

[0173] In some examples, such as the attached Figure 2 Appendix Figure 3 and appendix Figure 12 As shown, the connecting block 312 is snapped onto the panel 1. For example, the connecting block 312 is provided with a first snap-fit ​​structure 3102, and a second snap-fit ​​structure 11 is provided at a corresponding position on the bottom of the panel 1. One of the first snap-fit ​​structure 3102 and the second snap-fit ​​structure 11 is a buckle, and the other is a snap hole. The buckle and the snap hole are matched and snapped together, thereby realizing the snap-fit ​​of the transition body 311 onto the panel 1.

[0174] For example, the first snap-fit ​​structure 3102 is a snap-fit ​​hole (the number of snap-fit ​​holes on the same side can be one, two, three or more), and the second snap-fit ​​structure 11 is a snap hook (the number of snap hooks is the same as the number of snap-fit ​​holes).

[0175] In addition, when the connecting block 312 and the transition body 311 are located in the same horizontal plane, the lever 32 is provided with a relief groove 3222. The relief groove 3222 is configured to accommodate the swing positioning member 4. As shown above, the relief groove 3222 is provided on the lever body 322. This not only simplifies the assembly process of the swing positioning member 4, but also ensures that the swing positioning member 4 has sufficient deformation space.

[0176] In other examples, the connecting block 312 is located on the side of the transition body 311 facing the spring piece 51. One end (upper end) of the connecting block 312 is connected to the side of the transition body 311, and the other end (lower end) of the connecting block 312 extends downward to be movably connected to the lever 32 located below the transition body 31. That is, the lower end of the connecting block 312 is provided with the aforementioned first pin 3101 (not shown in the figure, but can be referenced). Figure 10 and Figure 11 (and are aware of the structural layout).

[0177] Based on the above example, the two sides of the transition body 311 distributed along the first direction are respectively fixedly connected to the two sides of the panel 1 at the corresponding positions. For example, the connection methods between the two include but are not limited to: snap-fit, riveting, welding, bonding, integral molding connection, etc.

[0178] In this example, the fixed connection method between the transition body 311 and the panel 1 can be referred to the fixed connection method between the connecting block 312 and the panel 1 described above, and will not be repeated here.

[0179] Furthermore, based on this example, one end of the swing positioning member 4 can be connected to one side of the transition body 311, and the other end of the swing positioning member 4 can be connected to a corresponding position on the side of the base 2. In this example, the swing positioning member 4 and the transition body 311 are located above the lever member 32.

[0180] In this embodiment of the invention, the transition body 311 is hinged to the base 2. For example, see... Figure 12 Each of the two sides of the transition body 311 distributed along the second direction is connected to a third pin 3103. A bracket 202 with a shaft hole is provided at the corresponding position on the side of the base 2. The third pin 3103 is rotatably sleeved in the shaft hole on the bracket 202 to realize the hinge connection between the transition body 311 and the base 2.

[0181] To increase the interaction area between panel 1 and transition body 311, so that they rotate synchronously, see [reference needed]. Figure 3 Furthermore, multiple first pressure ribs 12 can be provided at the bottom of panel 1, and the multiple first pressure ribs 12 abut against the corresponding positions on the top of the transition body 311.

[0182] Understandably, apart from the improved designs made to adapt to the embodiments of the present invention, such as the second snap-fit ​​structure 11 and the first pressure rib 12, the main structure of the panel 1 can adopt a panel structure commonly used in the art.

[0183] In this embodiment of the invention, the base 2 accommodates and fixes the moving contact assembly 5, the stationary contact assembly 6, etc. The base 2 can be designed as an integral structural component, that is, a single integral structural component is used to form the base. Alternatively, the base 2 can be composed of multiple separate structural components. Examples are given below:

[0184] In some examples, as shown in the appendix Figure 14 and attached Figure 15 As shown, base 2 is composed of multiple separate structural components, as illustrated in the attached diagram. Figure 15As shown, the base 2 includes a seat body 21 and a cover body 22. The seat body 21 has a receiving cavity 200 to receive the moving contact assembly 5 and the stationary contact assembly 6. The cover body 22 is detachably connected to the seat body 21 and covers the upper port of the receiving cavity 200. The cover body 22 is also used to hinge with the stroke amplification assembly 3.

[0185] In this embodiment of the invention, the cover 22 acts as a pressure plate, sealing the upper port of the accommodating cavity 200 of the seat 21 and providing support for the stroke amplification component 3.

[0186] The two sides of the cover 22 distributed along the first direction are respectively hinged to the corresponding lever members 32, that is, the aforementioned second pin 201 is provided on the aforementioned side of the cover 22. The middle of the two sides of the cover 22 distributed along the first direction are also connected to a swing positioning member 4. The position of the cover 22 connected to the swing positioning member 4 is located at its outermost end, while the position of the cover 22 connected to the lever member 32 is slightly offset inwards relative to its outermost end by a certain distance.

[0187] The middle positions of the two sides of the cover 22 distributed along the second direction are respectively hinged to the corresponding sides of the transition member 31, that is, the bracket 202 with shaft hole mentioned above is provided on the above side of the cover 22.

[0188] The drive unit 321 penetrates the cover 22 and extends into the receiving cavity 200 to interact with the spring piece 51, that is, as shown in the attached... Figure 15 As shown, the cover 22 has a through hole 221 at a corresponding position, and the drive unit 321 passes through the through hole 221 and extends into the receiving cavity 200 of the seat 21.

[0189] By designing the base 2 as a detachable connection between the seat 21 and the cover 22, the assembly of the internal components of the switch becomes more convenient and efficient.

[0190] Furthermore, the bottom of the cover 22 may also be provided with a plurality of second pressure ribs, which are used to abut against the top of the moving contact assembly 5 and / or the stationary contact assembly 6, so as to further position the moving contact assembly 5 and / or the stationary contact assembly 6.

[0191] For example, the top of the terminal connection section 511 of the spring 51 can abut against the second rib at the corresponding position on the bottom of the cover 22.

[0192] For the stationary contact assembly 6, it is understood that it includes a connected terminal block 52 and a contact piece with a stationary contact 60, such that the top of the contact piece abuts against the second rib at a corresponding position on the bottom of the cover 22.

[0193] The cover 22 can be detachably connected to the base 21 in a variety of ways, such as, but not limited to, snap-fit, riveting, screw connection, etc.

[0194] In other examples, see Figure 10 and Figure 11 The base 2 is an integral structural component. The base 2 includes a receiving cavity 200, which not only accommodates the moving contact assembly 5 and the stationary contact assembly 6, but also accommodates the stroke amplification assembly 3 and the swing positioning component 4. The corresponding positions on the inner sidewall of the receiving cavity 200 are respectively connected to the transition component 31, the lever component 32 and the swing positioning component 4.

[0195] The integrated structure design of base 2 also enables the various components inside the switch to work together.

[0196] Understandably, the aforementioned base 21 or the integrated base 2 includes not only a bottom cavity portion with a receiving cavity 200, but also an outer periphery portion connected to the upper end of the bottom cavity portion and surrounding the outside of the panel 1, so as to give the switch a good aesthetic appearance.

[0197] In some examples, the switch involved in the embodiments of the present invention is a wall switch, the base 2 of which can be installed in a junction box on the wall. Since the depth of the base 2 is designed to be small, the space occupied in the junction box is low.

[0198] The switches involved in the embodiments of the present invention can be classified according to their normal energization method as either normally closed switches or normally open switches.

[0199] As attached Figure 2 - Appendix Figure 3 As shown, when the switch is a normally closed switch, the moving contact 53 is located below the corresponding stationary contact 60, and the contact pressure between the moving contact 53 and the stationary contact 60 is provided by the spring 51.

[0200] As attached Figure 8 - Appendix Figure 9 As shown, when the switch is a normally open switch, the moving contact 53 is located above the corresponding stationary contact 60, and the contact pressure between the moving contact 53 and the stationary contact 60 is provided by the stroke amplification component 3.

[0201] Taking a single-pole double-pole switch as an example, it includes a pair of normally closed contacts consisting of a moving contact 53 and a stationary contact 60, and a pair of normally open contacts consisting of a moving contact 53 and a stationary contact 60. The normally closed and normally open contacts are located on both sides of the switch. In this embodiment of the invention, if the normally closed contact corresponds to the upturned side of the panel 1, it is called a normally closed single-pole double-pole switch; conversely, if the normally open contact corresponds to the upturned side of the panel 1, it is called a normally open single-pole double-pole switch.

[0202] Appendix Figure 3A schematic diagram of a normally closed single-pole double-control switch in the normally closed contact closed state is shown in the example. Figure 3 As shown, panel 1 and transition piece 31 are stabilized in the closed position under the action of swing positioning piece 4 (the right side is in an upward state, and the left side is in a downward state). At this time, the transition piece 31 on the left presses down on the lever piece 32 on the left, the drive part 321 on the left presses against the left elastic segment 512 of the spring piece 51, the moving contact 53 on the left separates from the stationary contact 60 on the left under the action of the drive part 321, and the normally open contact on the left is in the open state. And, the transition piece 31 on the right pulls up on the lever piece 32 on the right, the drive part 321 on the right separates from the right elastic segment 512 of the spring piece 51, the moving contact 53 on the right contacts the stationary contact 60 on the right under the elastic force of the right elastic segment 512 of the spring piece 51, the normally closed contact on the right is in the closed state, and they remain stable under the action of swing positioning piece 4.

[0203] When the normally closed single-pole double-control switch switches from the closed state to the open state at the normally closed contact, pressing the right side of panel 1 causes panel 1 and transition piece 31 to rotate clockwise under the pressing force. Simultaneously, both levers 32 rotate counterclockwise under the drive of transition piece 31. When rotated to a certain position, the drive part 321 on the left presses against the left elastic segment 512 of spring piece 51, and the drive part 321 on the right presses against the right elastic segment 512 of spring piece 51. The moving contact 53 on the left moves upward and remains separated from the stationary contact 60 on the left, while the moving contact 53 on the right moves downward and remains connected to the stationary contact 60 on the right (based on the elastic force of the right elastic segment 512). Although the normally closed contact on the right is in the connected state and the normally open contact on the left is in the open state, this state is unstable.

[0204] When the normally closed single-pole double-control switch switches to the normally closed contact open state, continue pressing the right side of panel 1. Panel 1 and transition piece 31 rotate clockwise under the pressing force. At the same time, both lever pieces 32 rotate counterclockwise under the drive of transition piece 31. Until panel 1 and transition piece 31 quickly pass the critical point under the action of swing positioning piece 4 and stop in a stable state, panel 1 and transition piece 31 are stabilized at the open position under the action of swing positioning piece 4 (its left side is in an upward state and its right side is in a downward state). At this time, the transition piece 31 on the right side presses down on the lever piece 32 on the right side, so that its driving part 321 presses against the right elastic section 512 of the spring piece 51. The moving contact 53 on the right side separates from the stationary contact 60 on the right side under the action of transition piece 31, and the normally closed contact on the right side is in the open state. Additionally, the transition member 31 on the left pulls the lever member 32 on the left upward, the drive part 321 on the left separates from the left elastic segment 512 of the spring piece 51, the moving contact 53 on the left contacts the stationary contact 60 on the left under the elastic force of the left elastic segment 512 of the spring piece 51, the normally open contact on the left is in the closed state, and they remain stable under the action of the swing positioning member 4.

[0205] It is evident that the normally closed switch described above has at least the following advantages:

[0206] (1) The contact pressure between the moving contact 53 and the stationary contact 60 is provided by the elastic force of the elastic segment 512 on the corresponding side of the spring sheet 51, which makes the contact pressure between the moving contact 53 and the stationary contact 60 stable and controllable.

[0207] (2) The separation between the moving contact 53 and the stationary contact 60 is provided by the pressing external force. When the moving contact 53 separates from the stationary contact 60, the driving part 321 on the transition member 31 pushes it open instantly. The separation speed is fast. Compared with the traditional rocker switch, which is prone to arcing due to the contact pressure changing from large to small, the normally closed switch provided in this embodiment of the invention significantly reduces the arcing phenomenon.

[0208] (3) The spring piece 51 is located below the stationary contact 60. The elastic segment 512 of the spring piece 51 has a large deformation capacity, which gives it a large operating force. This is particularly beneficial to improving the contact stability and contact speed between the moving contact 53 and the stationary contact 60, ensuring the reliability of the switch and further reducing the arcing phenomenon.

[0209] (4) By arranging the stroke amplification component 3, based on the lever amplification principle, the smaller stroke of the panel 1 can be converted into a larger stroke of the drive unit 321, thereby making the switching operation more reliable, which is also conducive to the ultra-thin development of the switch.

[0210] The working principle of a normally open single-pole double-control switch is similar to that of a normally closed single-pole double-control switch. The difference is that the contact pressure between the moving contact 53 and the stationary contact 60 is provided by the driving part 321 on the stroke amplification component 3 pressing down against the spring 51, and the separation between the moving contact 53 and the stationary contact 60 is provided by the elastic force of the elastic segment 512 on the corresponding side of the spring 51.

[0211] The working principle of a normally closed single-pole double-control switch can be easily understood by referring to the above-mentioned working principle of a normally open single-pole double-control switch, and will not be elaborated here.

[0212] In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0213] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
