Description

Technical Field

[0001] This application relates to the field of electrical switch technology, and in particular to a horizontal flat switch structure. Background Technology

[0002] As a fundamental control component of electrical systems, the structure of a switch directly affects its installation adaptability and operational flexibility. Currently, most switch assembly structures on the market, especially 110GHz switches, employ a vertical stacking assembly method, with functional components installed sequentially from bottom to top. This results in a relatively large overall height. In applications requiring low installation height or with limited space, such as slim distribution cabinets, recessed mounting panels, and low-profile instrument enclosures, existing switch products exhibit significant installation limitations, restricting their application scope.

[0003] Furthermore, some switch products rely on permanent magnets to enhance triggering or resetting force. Permanent magnets are at risk of demagnetization at high temperatures, and their magnetic permeability decreases significantly with increasing temperature. This results in insufficient triggering or weakened resetting force, affecting the switch's reliability and failing to meet the requirements of high-temperature operating conditions.

[0004] More importantly, existing switch structures generally require continuous power supply or mechanical force to maintain the contact's closed or open state after completing one opening and closing action. Once the power supply is abnormally interrupted, the contacts will automatically reset, making it difficult to maintain the target state. This poses safety hazards or functional defects in some applications that require maintaining the state even when power is off.

[0005] Based on this, those skilled in the art have proposed a horizontal flat switch structure, which provides a new solution to the above-mentioned technical problems. Summary of the Invention

[0006] To address the problems mentioned in the background art, this application provides a horizontal flat switch structure.

[0007] The horizontal flat switch structure provided in this application adopts the following technical solution: A horizontally flattened switch structure includes a housing structure. The housing structure includes a circuit board, a mounting plate, and a fixing plate arranged sequentially from top to bottom. A plurality of horizontal switches are mounted on the top of the mounting plate. Each horizontal switch includes an electromagnetic drive assembly arranged in a horizontal direction and a switch assembly installed between the mounting plate and the fixing plate. The electromagnetic drive assembly is electrically connected to the circuit board. A transmission assembly is provided between the electromagnetic drive assembly and the switch assembly. The switch assembly includes a spring top rod vertically slidably mounted inside the mounting plate. A movable spring is provided at the bottom of the spring top rod, and a first spring is provided between the spring top rod and the mounting plate. When the electromagnetic drive assembly is energized, it generates a magnetic field and drives its movable part to move linearly in the horizontal direction. The transmission assembly acts on the spring top rod, thereby driving the movable spring to move downward and connect with the contact in the fixed plate. When the electromagnetic drive assembly is de-energized, the first spring drives the spring top rod to reset, and the movable spring disconnects from the contact in the fixed plate.

[0008] Optionally, the electromagnetic drive assembly includes a first winding post electrically connected to the circuit board and a first coil core passing through the first winding post. A mounting base is fixed to the top of the mounting plate, and the first winding post and the first coil core are both mounted on the mounting base. The transmission assembly includes a push block, a swing arm one, and a swing arm two. A support frame is fixed to the top of the mounting plate and at one end of the mounting base. One end of the swing arm one is rotatably connected to the end of the first coil core, and the other end is rotatably connected to the swing arm two. The swing arm two is rotatably mounted on the top of the support frame. A first movable groove is opened on the inner side of the swing arm one, and a second movable groove is opened on the inner side of the swing arm two. The push block is rotatably and slidably mounted in the first movable groove and the second movable groove. The bottom ends of the push block are rounded. The push block is located directly above the corresponding spring top rod.

[0009] Optionally, the horizontal switch further includes a spring-loaded structure, which includes a connecting plate fixedly connected to the end of the first coil core away from the swing arm. An elastic element is installed between the connecting plate and the mounting base. The elastic element is used to generate a spring-loaded force to reset the first coil core after the electromagnetic drive assembly is de-energized.

[0010] Optionally, the elastic element is a pair of reverse double springs, with the two reverse double springs symmetrically installed between the connecting plate and the two sides of the mounting base.

[0011] Optionally, the elastic element is a return spring, which is installed between the connecting plate and the mounting base.

[0012] Optionally, a self-locking structure is also included. The self-locking structure is disposed on the top of the mounting plate and located between the plurality of horizontal switches. The self-locking structure is used to lock the position of the spring top rod after the contact between the moving spring and the contact in the fixed plate is connected, and to release the spring top rod when the unlocking signal is triggered so that it is reset under the action of the rebound force of the first spring.

[0013] Optionally, the self-locking structure includes a self-locking mounting bracket, a plurality of self-locking blocks, a self-locking top block, and a driving assembly; the self-locking mounting bracket is fixed to the top of the mounting plate and located at one end of the plurality of horizontal switches that are close to each other; the self-locking mounting bracket is a polygonal prism structure, the number of its outer facets being the same as the number of horizontal switches; each outer facet has a mounting cavity, and a self-locking block is slidably disposed in each mounting cavity; a polygonal mounting hole is provided on the inner side of the self-locking mounting bracket, the inner wall facets of the polygonal mounting hole corresponding one-to-one with the outer facets; each self-locking block has a first driving inclined surface at the end near the horizontal switch that cooperates with the corresponding spring top rod; a transmission block is fixed at the end of each self-locking block that extends into the inner side of the polygonal mounting hole; the transmission block... A second driving ramp is provided at one end away from the mounting cavity. A third spring is sleeved on the outside of the self-locking block, and the two ends of the third spring abut against the inner wall edge of the transmission block and the polygonal mounting hole, respectively. The self-locking top block is vertically slidably disposed inside the polygonal mounting hole. The top of the self-locking top block is provided with a driving edge that matches a plurality of the second driving ramps. A driving column is fixed to the top of the self-locking top block. A second spring is provided between the bottom of the self-locking top block and the top of the mounting plate. The driving assembly includes a mounting bracket fixed to the bottom of the circuit board. A second winding column is installed at the bottom of the mounting bracket. A second coil core passes through the second winding column. The second winding column is electrically connected to the circuit board. When the second coil core is energized, it can drive the self-locking top block to move downward.

[0014] Optionally, the first driving inclined surface is an inclined surface that slopes outward from top to bottom; the second driving inclined surface is an inclined surface that slopes inward from bottom to top, and the second driving inclined surface slides and abuts against the driving edge.

[0015] A method of using a horizontal, flat switch structure includes the following steps: Power-on triggering stage: The circuit board is energized to the first winding post. The first winding post generates a magnetic field that drives the first coil core to move horizontally, causing the first swing arm and the second swing arm to rotate relative to each other. This pushes the push block to move vertically downward and presses against the spring top rod, causing the moving spring to move downward and connect with the contact point inside the fixed plate. State holding stage: During the descent of the spring top rod, the self-locking block is driven to retract into the mounting cavity by the first driving inclined surface. At the same time, the self-locking block is pushed by the second driving inclined surface on the transmission block to move the self-locking top block down and compress the second spring. After the spring top rod passes the self-locking block, the self-locking block is reset and extended under the action of the third spring force, and is locked on the top of the spring top rod, so that the moving spring remains in the connected state after the circuit board is de-energized. Unlocking and Reset Phase: The circuit board is energized to the second winding post. The second coil core drives the self-locking top block to move down via the drive post to compress the second spring. After the drive face descends, it loses support for the second drive slope. The self-locking block retracts into the mounting cavity under the action of the third spring, releasing the lock on the spring top rod. The spring top rod resets under the action of the first spring and the elastic element, and the moving spring disconnects from the contact inside the fixed plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects: The electromagnetic drive assembly of this invention adopts a horizontal arrangement, and the driving direction is changed from vertical to horizontal. The horizontal motion is converted into vertical contact action through the transmission assembly. The overall height of the machine is determined only by the contact stroke, which greatly reduces the overall installation height of the switch product and realizes the flattening of the structure. It is suitable for thin equipment and low-profile enclosures with limited installation space. This invention employs an electromagnetic drive method using a first winding post and a first coil core, completely eliminating the need for permanent magnets and removing the reliability risks associated with high-temperature demagnetization, enabling the product to be used stably under special high-temperature conditions. After power failure, the invention is driven to reset by the combined rebound force of the first spring and the elastic element, which disperses the fatigue wear of the single elastic element, extends the service life of the product, and ensures the reliability of the reset action. This invention achieves mechanical self-locking retention of contacts in the power-off state through the setting of a self-locking structure, completely solving the shortcomings of existing switches that automatically reset when power is off, and meeting the special application requirements that need to maintain the on state when power is off.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-14 The present invention will now be described in further detail.

[0032] Reference Figures 1 to 3 The present invention provides a horizontal flat switch structure including a housing structure, which is composed of a circuit board 5, a mounting plate 1, and a fixing plate 9 stacked sequentially from top to bottom. A switch operation space is formed between the mounting plate 1 and the fixing plate 9. The circuit board 5 is fixed above the mounting plate 1 and is responsible for providing control current to each horizontal switch 20. Several horizontal switches 20 are mounted on the top of the mounting plate 1, and the horizontal switches 20 are evenly distributed along the circumference of the mounting plate 1.

[0033] Reference Figures 5 to 8 Each horizontal switch 20 includes an electromagnetic drive assembly, a transmission assembly, and a switch assembly, which work together to complete the connection and disconnection of the contacts.

[0034] The electromagnetic drive assembly is horizontally mounted on top of the mounting plate 1. A mounting base 14 is fixed to the top of the mounting plate 1. The first winding post 10 and the first coil core 11 are both mounted on the mounting base 14. The first coil core 11 passes through the interior of the first winding post 10 and can slide horizontally within the first winding post 10. The first winding post 10 is electrically connected to the circuit board 5 via a wire. When current is supplied to the first winding post 10 by the circuit board 5, the first winding post 10 generates a magnetic field, attracting the first coil core 11 towards the drive assembly and driving the first coil core 11 to move linearly in the horizontal direction.

[0035] The transmission assembly is located between the electromagnetic drive assembly and the switch assembly, responsible for converting the horizontal movement of the first coil core 11 into the vertical movement of the reed rod 7. The transmission assembly includes a push block 2, a first swing arm 3, and a second swing arm 4. A support frame 15 is fixed to the top of the mounting plate 1 and at one end of the mounting base 14. The second swing arm 4 is rotatably mounted on the top of the support frame 15, with the support frame 15 as the fulcrum. One end of the first swing arm 3 is rotatably connected to the end of the first coil core 11 via a pin, and the other end is rotatably connected to the second swing arm 4, forming a crank-connecting rod mechanism. A first movable groove 31 is opened on the inner side of the first swing arm 3, and a second movable groove 41 is opened on the inner side of the second swing arm 4. The push block 2 is rotatably and slidably mounted in the first movable groove 31 and the second movable groove 41 via pins at both ends, with the push block 2 positioned directly above the corresponding reed rod 7. The bottom ends of the push block 2 are provided with rounded corners 21 to ensure a smooth transition between the push block 2 and the top surface of the reed rod 7, avoiding rigid impact.

[0036] The switch assembly is installed between mounting plate 1 and fixed plate 9. A spring rod 7 is vertically slidably installed inside the through hole of mounting plate 1, and can slide up and down vertically. A movable spring 8 is fixedly connected to the bottom of the spring rod 7, and the movable spring 8 corresponds to the stationary contact in the fixed plate 9. A first spring 17 is provided between the spring rod 7 and mounting plate 1. The first spring 17 is in a pre-compressed state, constantly pushing the spring rod 7 upwards, so that the spring rod 7 remains in its upward position in its natural state, and the movable spring 8 is disconnected from the stationary contact.

[0037] Power-on trigger: Circuit board 5 supplies power to the first winding post 10, which generates a magnetic field, driving the first coil core 11 to move horizontally toward the transmission assembly. The horizontal displacement of the first coil core 11 causes the swing arm 3 to move. The swing arm 3 uses its hinge point with the swing arm 4 as the force transmission point, driving the swing arm 4 to rotate around the pin at the top of the support frame 15. The angle between the relative rotation of the swing arm 3 and the swing arm 4 decreases, and the change in the relative position of the first movable slot 31 and the second movable slot 41 drives the push block 2 to move downward. The push block 2 presses against the top surface of the spring top rod 7 through the rounded corner 21, pushing the spring top rod 7 to slide downward against the elastic force of the first spring 17, causing the movable spring 8 to move down to contact the stationary contact in the fixed plate 9, and the contact is connected.

[0038] Power-off reset: After the circuit board 5 is powered off, the magnetic field of the first winding post 10 disappears, and the attraction to the first coil core 11 is removed. At the same time, the first spring 17 releases its elastic potential energy, driving the spring top rod 7 to reset upwards. The top surface of the spring top rod 7 pushes the push block 2 upwards. The push block 2 drives the swing arm 3 and the swing arm 4 to rotate through the first movable groove 31 and the second movable groove 41, thereby pushing the first coil core 11 to reset horizontally. The moving spring 8 moves upwards with the spring top rod 7, disconnecting from the stationary contact, completing one opening and closing cycle.

[0039] Reference Figure 7 and Figure 8 Based on Embodiment 1, the horizontal switch 20 also includes a spring-back structure to provide additional active spring force for the power-off reset of the first coil core 11.

[0040] The springback structure includes a connecting plate 13 and an elastic element. The connecting plate 13 is fixedly connected to the end of the first coil core 11 away from the transmission assembly, i.e., the end of the swing arm 3, and moves horizontally synchronously with the first coil core 11. The elastic element is installed between the connecting plate 13 and the mounting base 14. When the first coil core 11 moves toward the transmission assembly, the elastic element is compressed or stretched to store energy; after power is cut off, the elastic element releases its elastic potential energy, applies a springback force to the connecting plate 13, and actively drives the first coil core 11 to reset.

[0041] The elastic element has the following two specific implementation methods: Implementation Method 1: The elastic element is a pair of reverse double springs 12, symmetrically mounted between the connecting plate 13 and the mounting base 14 on both sides. The mounting direction of the reverse double springs 12 is parallel to the movement direction of the first coil core 11. When the first coil core 11 moves horizontally, the two reverse double springs 12 bend symmetrically to store energy. After power is cut off, they release the elastic force synchronously, pushing the first coil core 11 back to its initial position. The symmetrical arrangement ensures balanced force on both sides, preventing the first coil core 11 from tilting during reset. Furthermore, the spring structure is thin and lightweight, which is beneficial for overall flattening.

[0042] Implementation Method 2: The elastic element is a return spring, which is installed between the connecting plate 13 and the mounting base 14. Its axis is parallel to the direction of movement of the first coil core 11, and the return force is provided by the compression and extension of the spring. The return spring has a simple structure and low cost, and is suitable for applications with general precision requirements.

[0043] The two types of elastic elements mentioned above work together with the first spring 17 to form a dual rebound mechanism. The first spring 17 is responsible for the reset of the spring top rod 7 and the moving spring 8, while the elastic elements are responsible for the reset of the first coil core 11 and the transmission assembly. The two work together to ensure that the reset action is quick and reliable, and the fatigue load borne by each elastic element is relatively reduced, thus extending the overall service life.

[0044] Reference Figures 9 to 14 Based on Embodiment 1 or Embodiment 2, the present invention also provides an embodiment configured with a self-locking structure 60 for achieving mechanical locking and retention of the contacts in the power-off state.

[0045] The self-locking structure 60 is fixed to the center area of ​​the top of the mounting plate 1, located between several horizontal switches 20 on the side that are close to each other, and synchronously controls the locking state of the multiple horizontal switches 20 in a centralized manner.

[0046] Reference Figure 14The self-locking structure 60 includes a self-locking mounting bracket 64, several self-locking blocks 65, a self-locking top block 66, and a drive assembly.

[0047] The self-locking mounting bracket 64 is a polygonal prism structure; in this embodiment, a hexagonal prism is used as an example. It is fixed to the top of the mounting plate 1. The number of its outer facets is the same as the number of horizontal switches 20, and each outer facet faces the corresponding horizontal switch 20. Each outer facet has a mounting cavity 641, the opening of which faces the corresponding horizontal switch 20, allowing the self-locking block 65 to slide and extend within it. A polygonal mounting hole is formed through the inner side of the self-locking mounting bracket 64 along the axial direction. The number of inner wall facets of the polygonal mounting hole is the same as the number of outer facets and they correspond one-to-one. The inner wall facets are approximately parallel to the outer facets, providing guiding support for the sliding movement of the transmission block 652.

[0048] Each locking block 65 is slidably installed in its corresponding mounting cavity 641, with the sliding direction being horizontal, i.e., along the normal direction of the corresponding outer edge. A first driving slope 651 is provided on the top of the self-locking block 65 near the horizontal switch 20. The first driving slope 651 is an outward-sloping slope from top to bottom. When the spring push rod 7 moves downward, its bottom edge contacts the first driving slope 651, sliding along the slope to push the self-locking block 65 inward into the mounting cavity 641, causing the self-locking block 65 to retract and not obstruct the spring push rod 7 from continuing to descend. A transmission block 652 is fixed to one end of the self-locking block 65 that extends into the polygonal mounting hole. A second driving slope 653 is provided on the end face of the transmission block 652 away from the opening of the mounting cavity 641. The second driving slope 653 is an inward-sloping slope from bottom to top. A third spring 69 is sleeved on the outside of the self-locking block 65. The two ends of the third spring 69 abut against the inner wall surface of the transmission block 652 and the inner wall edge surface of the polygonal mounting hole, respectively, to provide the self-locking block 65 with a continuous elastic force extending outward toward the horizontal switch 20.

[0049] The self-locking top block 66 is vertically slidably installed in the center of the polygonal mounting hole and can move up and down vertically within the polygonal mounting hole. The top of the self-locking top block 66 has driving facets 661 evenly distributed around its circumference, which are adapted to the second driving ramps 653 on each transmission block 652. Each driving facet 661 slides and abuts against the corresponding second driving ramp 653, forming a ramp transmission relationship between them: when the self-locking top block 66 moves upward, the driving facet 661 pushes upward along the second driving ramp 653, forcing each transmission block 652 to move outward, driving the self-locking block 65 to extend out of the mounting cavity 641; when the self-locking top block 66 moves downward, the supporting force of the driving facet 661 on the second driving ramp 653 weakens, and the elastic force of the third spring 69 will push the self-locking block 65 outward. When unlocking requires the self-locking block 65 to retract, the driving facet 661 moves downward and no longer provides radial support to the second driving ramp 653. The self-locking block 65 can retract under the action of external axial force, such as the reverse thrust of the spring top rod 7. A drive post 67 is fixed at the center of the top of the self-locking top block 66. The top of the drive post 67 extends out of the mounting cavity 641 for the drive assembly to apply force. A second spring 68 is provided between the bottom of the self-locking top block 66 and the top surface of the mounting plate 1. The second spring 68 is in a pre-compressed state and always pushes the self-locking top block 66 upward, so that the self-locking top block 66 remains in an upward position in its natural state. The drive edge 661 abuts against each of the second drive inclined surfaces 653, keeping each locking block 65 in the extended and locked state.

[0050] The driving component is an unlocking actuator of a self-locking structure 60, including a mounting bracket 61, a second winding post 62, and a second coil core 63. The mounting bracket 61 is fixed to the bottom of the circuit board 5 and extends downward to near the top surface of the mounting plate 1. The second winding post 62 is mounted on the bottom of the mounting bracket 61, and the second coil core 63 passes through the second winding post 62. The second winding post 62 is electrically connected to the circuit board 5. The axis of the second winding post 62 is aligned with the axis of the driving post 67. When the circuit board 5 supplies power to the second winding post 62, the second winding post 62 generates a magnetic field, driving the second coil core 63 to move downward. The bottom end of the second coil core 63 presses against the driving post 67, causing the self-locking top block 66 to slide downward against the elastic force of the second spring 68, thus performing the unlocking action.

[0051] The method of using the horizontal flat switch structure provided in this application is as follows: Power-on triggering stage: Circuit board 5 is energized to the first winding post 10, driving the spring top rod 7 to move downward as in Embodiment 1. During the downward movement of the spring top rod 7, its bottom edge contacts the first driving ramp 651 of the extended end of the self-locking block 65, pushing the self-locking block 65 inward into the mounting cavity 641 along the ramp. At the same time as the self-locking block 65 retracts, it pushes the driving ridge surface 661 of the self-locking top block 66 downward through the second driving ramp 653 on the transmission block 652, causing the self-locking top block 66 to move downward and compress the second spring 68. After the self-locking top block 66 retracts, it provides a channel for the retraction of the self-locking block 65. When the spring top rod 7 continues to move downward and passes the self-locking block 65, the self-locking block 65 quickly returns to its extended state under the elastic force of the third spring 69. At the same time, the second spring 68 pushes the self-locking top block 66 upward to restore its initial position, and the driving ridge surface 661 presses against the second driving ramp 653 again, maintaining the extended state of the self-locking block 65. At this time, the extended end of the self-locking block 65 is locked onto the top of the spring top rod 7, preventing it from moving upward under the action of the first spring 17, and the moving spring 8 remains in contact with the stationary contact.

[0052] State holding stage: After the circuit board 5 is de-energized to the first winding post 10, due to the mechanical locking of the self-locking block 65, the spring top rod 7 cannot move up to reset, and the moving spring 8 and the stationary contact inside the fixed plate 9 remain in the connected state, realizing the power-off self-locking function.

[0053] Unlocking and Reset Phase: When the contacts need to be disconnected, circuit board 5 energizes the second winding post 62. The second winding post 62 generates a magnetic field that drives the second coil core 63 to move downwards. The second coil core 63 pushes the self-locking top block 66 downwards through the drive post 67, compressing the second spring 68. After the self-locking top block 66 moves downwards, the drive ridge surface 661 gradually leaves the support area of ​​the second drive slope 653, and each transmission block 652 loses radial support force. Under the upward elastic force of the first spring 17, the top of the spring top rod 7 applies an inward pushing force to the self-locking block 65. Through the action of the reverse slope of the first drive slope 651, the self-locking block 65 overcomes the elastic force of the third spring 69 and retracts into the mounting cavity 641, releasing the lock on the spring top rod 7. The spring top rod 7 resets upwards under the elastic force of the first spring 17 and the elastic element, causing the moving spring 8 to disconnect from the stationary contact in the fixed plate 9. After the second winding post 62 is de-energized, the second spring 68 drives the self-locking top block 66 to reset, and the self-locking structure 60 returns to its initial waiting-to-lock state.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
