Description

Technical Field

[0001] The utility model relates to the technical field of switch equipment, and more specifically to the technical field of a magnetic trigger structure of a switch. Background Art

[0002] Switchgear is a device used to control the on / off and distribution of electric current and is widely used in power systems and electronic circuits. Its basic principle is to control the current path by controlling the state of the switching element (e.g., closed or open), thereby achieving the transmission and distribution of power. Existing switches are mainly divided into mechanical switches and electromagnetic switches.

[0003] Currently, most switches are mechanical structures, using direct button contact to achieve tactile feel and switching operation. Since mechanical switches rely on physical contact to switch circuits, long-term use will cause wear on the contact surface, which in turn affects the reliability and life of the switch. In addition, dust, dirt or oxide layers may cause poor contact on the contact surface, thereby affecting the stable transmission of current. In electromagnetic switches, such as relays, electromagnetic coils are required to drive the switching operation, which consumes a certain amount of electrical energy, especially when the power is on for a long time. In addition, electromagnetic switches generate heat during operation and require effective heat dissipation design, otherwise it will affect the performance and life of the switch. Utility Model Content

[0004] This utility model aims to address the technical problem of existing mechanical switches relying on physical contact to switch circuits, which can lead to wear of the contact surfaces over time, thus affecting the reliability and lifespan of the switch. This utility model provides a magnetic trigger structure for the switch. This structure utilizes magnetic force to switch the switch on and off over air. It is fully dustproof and waterproof, effectively preventing electrical leakage while also reducing mechanical wear and extending the service life.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The utility model provides a magnetic trigger structure of a switch, comprising a switch fixing component and a switch moving component movably arranged on the switch fixing component;

[0007] The switch moving assembly includes a moving part movably arranged on the switch fixing assembly and a first magnetic element arranged on the moving part;

[0008] The switch fixing assembly includes a middle magnetic assembly of the switch, which includes a switch base housing, a fourth magnetic element arranged on one side of the switch base housing, a mounting hole arranged on the other side of the switch base housing, and a magnetic conduction assembly arranged in the mounting hole. The first magnetic element cooperates with the magnetic conduction assembly to use magnetic force to realize the switch on and off through the air.

[0009] In one embodiment, the magnetic conduction component includes a first shock-absorbing layer, a conductive terminal, a conductive layer, an insulating layer, a second magnetic element, a second shock-absorbing layer, and a third magnetic element, which are arranged in sequence from top to bottom. The first shock-absorbing layer is fixed to the top of the mounting hole and is closely connected to the conductive terminal. The second shock-absorbing layer is fixed to the inner wall of the mounting hole. A movable gap is provided between the conductive terminal and the second shock-absorbing layer. The conductive layer, the insulating layer, and the second magnetic element are all movably arranged in the gap. The gap height is greater than the sum of the thicknesses of the second magnetic element, the insulating layer, and the conductive layer, and provides space for the second magnetic element to move up and down. The third magnetic element is located below the second shock-absorbing layer and is fixed to the switch base cover. The conductive terminal is connected to the external circuit through a wire.

[0010] The first magnetic element cooperates with the second magnetic element and the magnetic poles on adjacent sides of the two are opposite, the first magnetic element cooperates with the fourth magnetic element and the magnetic poles on adjacent sides of the two are opposite, and the second magnetic element cooperates with the third magnetic element and the magnetic poles on adjacent sides of the two are opposite.

[0011] Specifically, when the switch is closed to maintain the circuit path, the switch motion component drives the first magnetic element to the top of the first shock-absorbing layer under the action of external force. At this time, the first magnetic element, the second magnetic element, and the third magnetic element are arranged in sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction and attracting each other. The second magnetic element approaches the first magnetic element under the attraction of the first magnetic element, so that the conductive layer contacts the conductive terminal. At the same time, as the distance between the first magnetic element and the second magnetic element decreases, the attraction increases, and the switch motion component and the second magnetic element remain stationary, achieving self-locking capability.

[0012] When the switch is opened to break the circuit, the switch motion assembly moves the first magnetic element away from the first shock-absorbing layer under the action of external force, and the first magnetic element in the switch motion assembly remains stationary under the attraction of the fourth magnetic element. At this time, as the suction force between the first magnetic element and the second magnetic element decreases, the second magnetic element moves to the second shock-absorbing layer under the suction force of the third magnetic element until it stops, so that the conductive layer and the conductive terminal remain disconnected, thereby achieving self-locking capability.

[0013] In addition, the connection and disconnection of the circuit can be regarded as two different states of the circuit. The conductive terminal can also be set above the second shock-absorbing layer, and the height from the second shock-absorbing layer is the sum of the thicknesses of the second magnetic element, the insulating layer and the conductive layer. After the second magnetic element moves toward the second shock-absorbing layer, the conductive layer contacts the conductive terminal. At this time, the behavior required to control the connection and disconnection of the circuit is opposite to the original behavior.

[0014] Two sets of conductive terminals can be configured based on the different positions of the second magnetic element in the two switch states, thereby achieving a single-pole double-throw (SPDT) function. This solution achieves a self-locking switch function without the use of other mechanical components such as elastic elements. The size of the switch in this solution can be increased or decreased depending on the application scenario and manufacturing process.

[0015] In one embodiment, the moving component is connected to the switch fixing assembly by sliding, pressing or rotating.

[0016] Specifically, the movement of the switch motion component to achieve the circuit state change may include, but is not limited to, sliding, pressing, and rotating.

[0017] In one embodiment, the switch fixing assembly further includes a switch top plate and a switch base cover plate, and the switch top plate, the switch middle magnetic assembly and the switch base cover plate are arranged in sequence from top to bottom.

[0018] In one embodiment, the moving part is connected to the switch top plate by sliding;

[0019] a fifth magnetic element on the other side of the bottom of the moving part, the fifth magnetic element cooperating with the second magnetic element and having the same magnetic poles on adjacent sides thereof;

[0020] The switch top plate is a flat plate, and a sliding groove with a through end is provided in the middle of the upper surface of the switch top plate. A protrusion that slides and is engaged in the sliding groove is provided at the bottom of the moving component. The fifth magnetic element and the first magnetic element are both embedded in the lower surface of the protrusion, and a limit block is provided at the through end of the sliding groove to prevent the protrusion from sliding out of the sliding groove.

[0021] Specifically, a plurality of identical trigger structures can be provided in the magnetic component in the middle of the switch, so that when the first magnetic element moves to different positions, different circuits are controlled respectively to realize different functions.

[0022] In one embodiment, the moving component is rotatably connected to the switch top plate (the switch top plate is connected to the switch top fixed plate, the upper surface of the switch top fixed plate is provided with an axle seat, and the middle part of the lower surface of the moving component is provided with a fulcrum shaft) by pressing, and a fifth magnetic element is provided on the other side of the bottom of the moving component, the first magnetic element and the fifth magnetic element are respectively located on both sides of the fulcrum shaft, the fifth magnetic element cooperates with the fourth magnetic element and the magnetic poles of the adjacent sides are opposite; the first magnetic element cooperates with the second magnetic element and the magnetic poles of the adjacent sides are opposite.

[0023] In one embodiment, the moving component is connected to the switch top plate in a rotational manner;

[0024] The moving part is a strip plate, the switch top plate is a fan plate, one end of the moving part is movably connected to the top of the fan plate through a rotating shaft, and the first magnetic element is arranged on the lower surface of the moving part away from the rotating shaft.

[0025] In one embodiment, the moving component is connected to the switch fixed assembly by rotation;

[0026] The switch base housing and the moving part are both annular structures. The moving part is rotatably arranged in the annular hole of the switch base housing. The first magnetic element is arranged on the outer wall of the moving part, and the fourth magnetic element and the magnetic conduction component are arranged on the inner wall of the switch base housing.

[0027] In one embodiment, all magnetic components and conductive terminals are sealed in the switch movement assembly and the switch mid-magnetic assembly.

[0028] In one embodiment, all magnetic elements are made of one or more materials selected from the group consisting of magnets, neodymium iron boron, and ferrite.

[0029] Specifically, all magnetic components can be made of different magnetic materials as long as their functions are met, including but not limited to: magnets, neodymium iron boron and ferrite.

[0030] The beneficial effects of the utility model are as follows:

[0031] Compared with mechanical switches, the service life of mechanical switches is mainly affected by the frequency of use. Taking household appliance switches as an example, their service life is between 100,000 and 5 million presses. Frequent use will lead to a reduction in usage time. The present patent utilizes the change in suction between the first magnetic element, the second magnetic element, and the third magnetic element to control the circuit in the air, and uses the fourth magnetic element to complete the self-locking function of the switch. The four magnetic elements and the conductive terminals can all be sealed by the sealing plate, which not only has the advantages of dust and corrosion resistance, but also has the advantages of isolating the circuit and preventing electrical leakage of the conductive terminals. In this structure, mechanical wear is no longer the main factor affecting the service life of the switch. Its service life is mainly affected by magnetic attenuation. Taking the common neodymium iron boron magnet as an example, in a natural environment, the magnetic attenuation is slow, and this structure can still function.

[0032] 2. Compared with electromagnetic structures such as relays, which require an external power supply to operate and require the design of corresponding control circuits, coils, and magnetic cores, the present invention achieves the same function in a more efficient and convenient manner, while also reducing operating and maintenance costs. Furthermore, electromagnetic structures require magnetic cores and coils, which are millimeter-sized. In the present invention, the magnetic elements can be manufactured using micromachining technology to small sizes, such as millimeters, micrometers, or even nanometers. Therefore, the present invention is widely applicable in the fields of microelectronic devices and microsensors. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] To make the technical problems, technical solutions, and technical effects of the present invention more clear, the following will be combined with the accompanying drawings of the embodiments of the present invention to provide a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of the embodiments.

[0072] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0073] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0074] The utility model provides a magnetic trigger structure of a switch, a switch fixing component and a switch moving component 18 movably arranged on the switch fixing component;

[0075] The switch moving assembly 18 includes a moving part 14 movably arranged on the switch fixing assembly, and a first magnetic element 1 arranged on the moving part 14;

[0076] The switch fixing assembly includes a switch middle magnetic assembly 20, which includes a switch base housing 8, a fourth magnetic element 10 arranged on one side of the switch base housing 8, a mounting hole arranged on the other side of the switch base housing 8, and a magnetic conduction assembly arranged in the mounting hole. The first magnetic element 1 cooperates with the magnetic conduction assembly to realize the switch on and off through magnetic force.

[0077] The magnetic conduction component includes a first shock-absorbing layer 2, a conductive terminal 3, a conductive layer 4, an insulating layer 5, a second magnetic element 6, a second shock-absorbing layer 9 and a third magnetic element 7, which are arranged in sequence from top to bottom. The first shock-absorbing layer 2 is fixed to the top of the mounting hole and is closely connected to the conductive terminal 3. The second shock-absorbing layer 9 is fixed to the inner wall of the mounting hole. A movable gap is provided between the conductive terminal 3 and the second shock-absorbing layer 9. The conductive layer 4, the insulating layer 5 and the second magnetic element 6 are all movably arranged in the gap. The height of the gap is greater than the sum of the thicknesses of the second magnetic element 6, the insulating layer 5 and the conductive layer 4, and provides space for the second magnetic element 6 to move up and down. The third magnetic element 7 is located below the second shock-absorbing layer 9 and is fixed to the switch base cover 17. The conductive terminal 3 is connected to the external circuit through a wire 12.

[0078] The first magnetic element 1 cooperates with the second magnetic element 6 and the magnetic poles on adjacent sides of the two are opposite, the first magnetic element 1 cooperates with the fourth magnetic element 10 and the magnetic poles on adjacent sides of the two are opposite, and the second magnetic element 6 cooperates with the third magnetic element 7 and the magnetic poles on adjacent sides of the two are opposite.

[0079] The working process is as follows:

[0080] When the switch is closed to maintain the circuit path, the switch motion component 18, under the action of external force, drives the first magnetic element 1 to the top of the first shock-absorbing layer 2. At this time, the first magnetic element 1, the second magnetic element 6, and the third magnetic element 7 are arranged in sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction and attracting each other. The second magnetic element 6 approaches the first magnetic element 1 under the attraction of the first magnetic element 1, so that the conductive layer 4 contacts the conductive terminal 3. At the same time, as the distance between the first magnetic element 1 and the second magnetic element 6 decreases, the attraction increases, and the switch motion component 18 and the second magnetic element 6 remain stationary, achieving self-locking capability. When the switch is opened to break the circuit, the switch motion component 18 moves the first magnetic element 1 away from the first shock-absorbing layer 2 under the action of external force, and the magnetic elements in the switch motion component 18 remain stationary under the attraction of the fourth magnetic element 10. At this time, as the suction force between the first magnetic element 1 and the second magnetic element 6 decreases, the second magnetic element 6 moves to the second shock-absorbing layer 9 under the suction force of the third magnetic element 7 until it stops, so that the conductive layer 4 and the conductive terminal 3 remain disconnected, achieving self-locking capability.

[0081] The working principle of this embodiment is as follows: Assume that the attraction between the first magnetic element 1 and the second magnetic element 6 is F 12 The sum of the gravity on the second magnetic element 6 and the insulating layer 5 and the conductive layer 4 attached to the surface is G2, and the attraction between the second magnetic element 6 and the third magnetic element 7 is F 23 When the switch is disconnected, the first magnetic element 1 is away from the second magnetic element 6, and the attraction force F between the first magnetic element 1 and the second magnetic element 6 is 12 Gradually reduce when the force meets:

[0082] F 12 <F 23 +G2; (1)

[0083] The second magnetic element 6 moves toward the third magnetic element 7, the conductive layer 4 is disconnected from the conductive terminal 3, and the circuit is broken. When the switch is closed, the first magnetic element 1 approaches the second magnetic element 6, and the first magnetic element 1 and the second magnetic element 6 have an attractive force F. 12 Gradually increase, when the force meets:

[0084] F 12 >G2+F 23 ; (2)

[0085] The second magnetic element 6 moves toward the first magnetic element 1, and the conductive layer 4 contacts the conductive terminal 3, thus establishing a circuit path. It should be noted that the force analysis in formulas (1) and (2) is the force condition that needs to be satisfied when the gravity on the second magnetic element 6 is perpendicular to the third magnetic element 7. When the structure is turned upside down, that is, the gravity on the second magnetic element 6 is reversed and perpendicular to the third magnetic element 7, the inequality formula (1) will become:

[0086] F 12 +G2 <F 23 ; (3)

[0087] Inequality formula (2) will become:

[0088] F 12 +G2>F 23 ; (4)

[0089] Based on the magnetic switch structure proposed in this utility model, there are the following different specific embodiments:

[0090] Example 1

[0091] like Figures 1 to 8 As shown, the sliding switch embodiment designed according to the magnetic switch structure of the present invention includes a switch movement component 18, a switch top plate 19, a switch middle magnetic component 20 and a switch base sealing plate 17. The switch movement component 18 has a first magnetic element 1, a fifth magnetic element 11 and a moving part 14. The first magnetic element 1 and the fifth magnetic element 11 are respectively fixed on the left and right sides of the sealed moving part 14. The switch top plate 19 is composed of a limit block 15 and a sliding groove 16. The sliding groove 16 provides a left and right movement space for the moving part 14. The switch top plate 19 completely seals the switch middle magnetic component 20. In the switch middle magnetic component 20, the first shock-absorbing layer 2 is fixed at the top and is closely connected to the conductive terminal 3. The conductive terminal 3 is closely attached to the lower part of the first shock-absorbing layer 2. The surface of the second magnetic element 6 is sequentially attached with the insulating layer 5 and the conductive layer 4 from bottom to top. The second shock-absorbing layer 9 is located below the second magnetic element 6 and is fixed to the inner wall of the switch base housing 8. A movable gap is provided between the conductive terminal 3 and the second shock-absorbing layer 9. The height of the gap is greater than the sum of the thicknesses of the second magnetic element 6, the insulating layer 5, and the conductive layer 4, and provides space for the second magnetic element 6 to move up and down. The third magnetic element 7 is located below the second shock-absorbing layer 9 and is fixed to the switch base sealing plate 17. The wire 12 is used to connect the conductive terminal 3 and the external terminal 13.

[0092] The working process is as follows: when the switch is closed to maintain the circuit path, the switch motion component 18 moves to the right under the action of external force, and drives the first magnetic element 1 to the top of the first shock-absorbing layer 2. At this time, the first magnetic element 1, the second magnetic element 6, and the third magnetic element 7 are arranged in sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction and attracting each other. The second magnetic element 6 approaches the first magnetic element 1 under the attraction of the first magnetic element 1, so that the conductive layer 4 contacts the conductive terminal 3. At the same time, as the distance between the first magnetic element 1 and the second magnetic element 6 decreases, the attraction increases, and the switch motion component 18 and the second magnetic element 6 remain stationary, realizing self-locking capability.

[0093] When the switch is turned off to break the circuit, the switch motion component 18 moves the first magnetic element 1 and the fifth magnetic element 11 to the left under the action of external force. At this time, the first magnetic element 1 is away from the first shock-absorbing layer 2 and comes directly above the fourth magnetic element 10. The first magnetic element 1 and the fourth magnetic element 10 attract each other to keep the switch motion component 18 stationary, and the fifth magnetic element 11 comes directly above the first shock-absorbing layer 2. The fifth magnetic element 11 and the second magnetic element 6 repel each other. Under the suction force of the third magnetic element 7 and the repulsion of the fifth magnetic element 11, the second magnetic element 6 moves to the second shock-absorbing layer 9 until it stops, so that the conductive layer 4 and the conductive terminal 3 remain disconnected, realizing self-locking capability.

[0094] Example 2

[0095] like Figures 9 to 17 The figure shows another use of a magnetic switch structure in the present invention. Compared to the sliding switch of Example 1, Example 2 implements a push switch. The main difference is that the sliding groove 16 and limit block 15 of the switch top plate 19 of Example 1 are eliminated. Instead, a shaft seat 162 is used. The shaft seat 162 is fixed to the switch top fixed plate 192, and a fulcrum shaft 152 is added to the switch motion assembly 18. After the fulcrum shaft 152 and shaft seat 162 are installed, the switch motion assembly 18 can rotate clockwise and counterclockwise around the shaft 162. The remaining structure and function of the switch central magnetic assembly 20 and the base cover plate 17 remain unchanged.

[0096] The working process is as follows: through the overall design of the device, when the switch is closed to maintain the circuit path, the switch motion component 18 rotates clockwise under the action of external force in the front view, driving the first magnetic element 1 to the top of the first shock-absorbing layer 2, so that the attraction between the first magnetic element 1 and the second magnetic element 6 increases, and the second magnetic element 6 approaches the first magnetic element 1 under the attraction of the first magnetic element 1, so that the conductive layer 4 contacts the conductive terminal 3. At the same time, as the distance between the first magnetic element 1 and the second magnetic element 6 decreases, the attraction increases, and the switch motion component 18 and the second magnetic element 6 remain stationary, realizing self-locking capability. When the switch is disconnected to break the circuit, the switch motion component 18 rotates counterclockwise under the action of external force in the front view, and the fifth magnetic element 11 comes directly above the fourth magnetic element 10. The fifth magnetic element 11 and the fourth magnetic element 10 attract each other to keep the switch motion component 18 stationary. As the first magnetic element 1 moves away from the first shock-absorbing layer 2, the suction force of the first magnetic element 1 on the second magnetic element 6 decreases. The second magnetic element 6 moves to the second shock-absorbing layer 9 under the suction force of the third magnetic element 7 until it stops, so that the conductive layer 4 and the conductive terminal 3 remain disconnected, achieving self-locking capability.

[0097] Example 3

[0098] like Figures 18 to 28 As shown, another use of a magnetic switch structure in the present invention. Compared with the sliding switch in Example 1, Example 3 is an implementation method of a rotary switch. The main changes are the cancellation of the fifth magnetic element 11 of the switch motion component 18, and the cancellation of the sliding groove 16 and the limit block 15 of the switch top plate 19. Instead, a rotating shaft 21 is added to the magnetic component 20 in the middle of the switch. One end of the switch motion component 18 is rigidly connected to the rotating shaft 21, and the first magnetic element 1 is fixed inside the other end. The switch motion component 18 can rotate in a plane with the rotating shaft 21 as the center.

[0099] The working process is as follows: through the overall design of the device, when the switch is closed to maintain the circuit path, the switch motion component 18 rotates clockwise under the action of external force through the rotating shaft 21 in a top view, driving the first magnetic element 1 to the top of the first shock-absorbing layer 2, so that the attraction between the first magnetic element 1 and the second magnetic element 6 increases, and the second magnetic element 6 approaches the first magnetic element 1 under the attraction of the first magnetic element 1, so that the conductive layer 4 contacts the conductive terminal 3. At the same time, as the distance between the first magnetic element 1 and the second magnetic element 6 decreases, the attraction increases, and the switch motion component 18 and the second magnetic element 6 remain stationary, realizing self-locking capability. When the switch is opened to break the circuit, the switch motion component 18 rotates counterclockwise under the action of external force from a top view, the first magnetic element 1 moves away from the first shock-absorbing layer 2, and the second magnetic element 6 moves to the second shock-absorbing layer 9 under the suction of the third magnetic element 7 until it stops, so that the conductive layer 4 and the conductive terminal 3 remain disconnected. At the same time, the first magnetic element 1 comes to the top of the fourth magnetic element 10 and attracts each other with the fourth magnetic element 10 to achieve self-locking capability.

[0100] Example 4:

[0101] like Figures 29 to 34 As shown, another use of a magnetic switch structure in the present invention. Compared with the sliding switch in Example 1, Example 4 is an implementation of a knob switch. The main changes are the cancellation of the fifth magnetic element 11 of the switch motion assembly 18, and the cancellation of the sliding groove 16 and the limit block 15 of the switch top plate 19. A switch base inner shell 82 is added to the switch base outer shell 8, the first magnetic element 1 is fixed in the switch motion component 14 and sealed with the first magnetic element sealing plate 193, and the switch motion assembly 18 rotates around its own center of circle.

[0102] The operating process is as follows: Through the overall design of this device, when the switch is closed to maintain the circuit, the switch motion assembly 18 rotates under the action of an external force. From a top view, it rotates clockwise, driving the first magnetic element 1 above the first damping layer 2. This increases the attractive force between the first magnetic element 1 and the second magnetic element 6. Under the attraction of the first magnetic element 1, the second magnetic element 6 approaches the first magnetic element 1, bringing the conductive layer 4 into contact with the conductive terminal 3. At the same time, as the distance between the first magnetic element 1 and the second magnetic element 6 decreases, the attractive force increases, and the switch motion assembly 18 and the second magnetic element 6 remain stationary, achieving self-locking capability. When the switch is opened to disconnect the circuit, the switch motion assembly 18 rotates counterclockwise from a top view under the action of an external force, moving the first magnetic element 1 away from the first damping layer 2. The second magnetic element 6, under the attraction of the third magnetic element 7, moves to the second damping layer 9 until it stops, maintaining the disconnection between the conductive layer 4 and the conductive terminal 3. At the same time, the first magnetic element 1 comes directly above the fourth magnetic element 10, attracting each other and achieving self-locking capability.
