Description
Technical Field
[0001] This utility model relates to the field of membrane switch technology, and more specifically, to a high-reliability superconducting sheet membrane switch. Background Technology
[0002] As electronic devices develop towards higher reliability and lower energy consumption, traditional membrane switches, due to insufficient anti-accidental touch capability, high conductive loss, and easy structural damage, are unable to meet the application requirements of high-end fields such as precision instruments and aerospace. Against this background, a membrane switch with an efficient anti-accidental touch mechanism, low energy loss, and high structural stability has emerged. A search revealed that publication number CN111863492A discloses a high-reliability superconducting membrane switch, belonging to the field of membrane switch technology. It includes a substrate layer and a switch body fixedly disposed on the upper part of the substrate layer. A positive electrode ring is disposed on the upper part of the substrate layer, and a negative electrode plate is disposed in the middle of the positive electrode ring. The switch body includes a ring-shaped support portion and a pressing portion disposed on the upper part of the support portion. A conductive portion is disposed on the inner side of the pressing portion, and several limiting portions are arranged around the inner wall of the support portion. The limiting portion includes a support seat fixedly connected to the inner wall of the support portion and a support plate rotatably disposed at the end of the support seat via a pin. The output of the membrane switch-related signal is achieved by pressing the pressing portion twice consecutively, effectively preventing the membrane switch from being opened due to accidental contact with the pressing portion. It has the advantages of simple structure, convenient use, and good anti-accidental contact effect. During the development of this utility model, the inventors discovered the following problems with the existing technology: Existing membrane switch designs with obvious shortcomings in preventing accidental touch often lack sophisticated anti-accidental touch structures and rely solely on simple press-triggered methods, making them highly susceptible to malfunctions due to external touches or operational errors. In addition, traditional membrane switches using ordinary conductive material substrates suffer from drawbacks such as high resistance loss, significant energy waste during current transmission, and limited conductivity and response speed. Therefore, a highly reliable superconducting thin-film switch is proposed to address the above problems. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-reliability superconducting thin-film switch to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-reliability superconducting sheet-type membrane switch, comprising an anti-accidental touch mechanism, a membrane assembly, a miniature electric lifting rod, and a support assembly. The support assembly is provided on the side of the anti-accidental touch mechanism, and the miniature electric lifting rod is provided above the support assembly, while the membrane assembly is provided below the electric lifting rod.
[0005] Preferably, the anti-accidental touch mechanism includes a pushing component, a snap-fit component, and a restoring component, wherein the snap-fit component is mounted on the side of the pushing component, and the restoring component is provided on the side of the snap-fit component away from the pushing component.
[0006] Preferably, the pushing assembly includes a first button, a first pushing rod, and a first spring, wherein the first pushing rod is mounted on the side of the first button, and the first spring is provided on the side of the first pushing rod away from the first button.
[0007] Preferably, the buckle assembly includes a slider, a locking block, and a locking slot plate, wherein the locking block is mounted on the side of the slider, and the locking block is provided on the side away from the slider.
[0008] Preferably, the recovery assembly includes a second button, a second push rod, and a second spring, wherein the second push rod is mounted on the side of the second button, and the second spring is provided on the side of the second push rod away from the second button.
[0009] Preferably, the thin film assembly includes a superconducting substrate, a stress buffer sheet, and an electrode thin film, wherein the stress buffer sheet is mounted above the superconducting substrate, and the electrode thin film is mounted above the stress buffer sheet.
[0010] Preferably, the electrode film includes a negative electrode plate, a positive electrode plate, and a mounting plate, and the positive electrode plate is disposed on the side of the negative electrode plate, and the mounting plate is mounted below the positive electrode plate.
[0011] Preferably, the support assembly includes a base plate, a support plate, and a top plate, with the support plate mounted above the base plate and the top plate mounted above the support plate.
[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this high-reliability superconducting sheet-type membrane switch improves operational safety and reliability through an anti-accidental-touch mechanism. Through the coordinated operation of the pushing component, the snap-fit component, and the reset component, the switch can only be triggered when the operator actively presses the pushing component to make the snap-fit component contact with the membrane component. This, combined with the micro electric lifting rod driving the conductive part to achieve indirect conduction, allows the switch to be triggered. The reset component allows the snap-fit component to reset and disconnect in time, effectively preventing accidental triggering of the membrane component due to accidental contact, thus building a solid defense for the stable operation of the switch.
[0013] Compared with existing technologies, this high-reliability superconducting sheet-type thin-film switch utilizes the superconducting substrate of the thin-film assembly. Its zero-resistance characteristic significantly reduces energy loss during current transmission, greatly improving the switch's conductivity and response speed. Furthermore, the addition of a stress buffer provides reliable protection for the internal structure. When the thin-film assembly is subjected to external forces, it can promptly absorb and disperse these forces, preventing damage to the superconducting substrate and electrode films due to stress concentration, thus extending the switch's lifespan. Simultaneously, a stable support assembly provides robust support for each component, ensuring stable overall performance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0020] As attached Figures 1 to 4The high-reliability superconducting sheet-type membrane switch shown includes an anti-accidental touch mechanism 1, a membrane assembly 2, a miniature electric lifting rod 3, and a support assembly 4. The support assembly 4 is arranged on the side of the anti-accidental touch mechanism 1, the miniature electric lifting rod 3 is arranged above the support assembly 4, and the membrane assembly 2 is arranged below the miniature electric lifting rod 3.
[0021] Specifically: The support assembly 4 of the membrane switch provides stable support for the entire switch. Through a stable three-dimensional frame structure, it ensures that each component is installed securely. The miniature electric lifting rod 3 is installed on the top plate 25 of the support assembly 4. After receiving a control signal, it can achieve vertical lifting movement and drive the conductive part and the upper part of the anti-accidental contact mechanism 1 to make contact. The anti-accidental contact mechanism 1 is located on the side and works with the membrane assembly 2 to ensure the reliable operation of the switch. When the switch needs to be triggered, the operator presses the anti-accidental contact mechanism 1 to make contact with the surface of the membrane assembly 2, and then activates the miniature electric lifting rod 3 to push the conductive part to make contact with the upper surface of the anti-accidental contact mechanism 1, thereby making indirect contact between the conductive part and the membrane assembly 2 to realize the function of the switch. When triggering is not required, the operator can press the anti-accidental contact mechanism 1 to return it to its original position, thereby preventing the membrane assembly 2 from being accidentally triggered due to accidental contact. Example
[0022] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the anti-accidental touch mechanism 1 includes a pushing component 5, a latching component 6, and a restoring component 7. The latching component 6 is mounted on the side of the pushing component 5, and the restoring component 7 is located on the side of the latching component 6 away from the pushing component 5. When the switch needs to be triggered, the operator needs to press the pushing component 5 to push the latching component 6 into contact with the membrane component 2. When the switch does not need to be triggered, the operator presses the restoring component 7 to return the latching component 6 to its original position, thereby disconnecting the connection between the latching component 6 and the membrane component 2.
[0023] In a preferred embodiment, the pushing assembly 5 includes a first button 8, a first pushing rod 9, and a first spring 10. The first pushing rod 9 is mounted on the side of the first button 8, and the first spring 10 is provided on the side of the first pushing rod 9 away from the first button 8. When the first button 8 in the pushing assembly 5 is pressed by an external force, it drives the first pushing rod 9 to move. At this time, the first spring 10 will extend, and the first pushing rod 9 pushes the buckle assembly 6 to connect with the film assembly 2.
[0024] In a preferred embodiment, the snap-fit assembly 6 includes a slider 11, a locking block 12, and a locking plate 13. The locking block 12 is mounted on the side of the slider 11, and the locking plate 13 is provided on the side of the locking block 12 away from the slider 11. The first push rod 9 pushes the slider 11 in the snap-fit assembly 6 to move, so that the locking block 12 on the side of the slider 11 locks with the locking plate 13, thereby connecting the film assembly 2 and the snap-fit assembly 6. At this time, the film assembly 2 can be triggered.
[0025] In a preferred embodiment, the restoration component 7 includes a second button 14, a second push rod 15, and a second spring 16. The second push rod 15 is mounted on the side of the second button 14, and the second spring 16 is provided on the side of the second push rod 15 away from the second button 14. When it is necessary to restore the buckle component 6 to its initial state, the operator needs to press the second button 14 to move the second push rod 15. At this time, the second spring 16 is in an extended state, and the push block 12 retracts and disengages from the slot. At this time, the first spring 10 wants to return to its original state, thereby pulling the block 12 back to its original position, so that the buckle component 6 and the film component 2 are disengaged.
[0026] In a preferred embodiment, the thin-film assembly 2 includes a superconducting substrate 17, a stress buffer sheet 18, and an electrode film 19. The stress buffer sheet 18 is mounted on top of the superconducting substrate 17, and the electrode film 19 is mounted on top of the stress buffer sheet 18. The superconducting substrate 17 has zero resistance characteristics, which can greatly reduce energy loss during current transmission and improve the conductivity and response speed of the switch. The stress buffer sheet 18 is mounted on top of the superconducting substrate 17. When the thin-film assembly 2 is subjected to external force, the stress buffer sheet 18 can absorb and disperse the external force, preventing the superconducting substrate 17 and the electrode film 19 from being damaged due to stress concentration, and protecting the integrity of the internal structure.
[0027] In a preferred embodiment, the electrode film 19 includes a negative electrode plate 20, a positive electrode plate 21, and a mounting plate 22. The positive electrode plate 21 is disposed on the side of the negative electrode plate 20, and the mounting plate 22 is mounted below the positive electrode plate 21. The mounting plate 22 is used to fix the electrode film 19 on the stress buffer sheet 18 to ensure the stability of the position of the electrode film 19. When the film assembly 2 is triggered, the negative electrode plate 20 and the positive electrode plate 21 form a conductive path to realize the conduction function of the switch and complete the transmission of electrical signals.
[0028] In a preferred embodiment, the bracket assembly 4 includes a base plate 23, a support plate 24, and a top plate 25. The support plate 24 is installed above the base plate 23, and the top plate 25 is installed above the support plate 24. The base plate 23, support plate 24, and top plate 25 of the bracket assembly 4 form a stable frame structure, providing a solid installation foundation for the miniature electric lifting rod 3 and the membrane assembly 2.
[0029] The working process of this utility model is as follows: First, the base plate 23, support plate 24 and top plate 25 of the bracket assembly 4 form a stable frame to provide solid support for other components. When the switch needs to be triggered, the operator presses the push component 5 of the anti-accidental touch mechanism 1. The first button 8 drives the first push rod 9 to move, the first spring 10 extends, and pushes the slider 11 in the buckle assembly 6 to move, so that the buckle 12 locks with the buckle plate 13. The anti-accidental touch mechanism 1 contacts the film assembly 2. Then the micro electric lifting rod 3 is activated, which drives the conductive part to contact the upper surface of the anti-accidental touch mechanism 1, realizing indirect contact and conduction between the conductive part and the film assembly 2. The negative electrode plate 20 and the positive electrode plate 21 of the electrode film 19 form a conductive path to transmit electrical signals.
[0030] When triggering is not required, pressing the second button 14 of the reset component 7 moves the second push rod 15, causing the second spring 16 to extend and push the locking block 12 out of the slot. The first spring 10 pulls the locking block 12 to reset and disconnect the connection. The zero-resistance characteristic of the superconducting substrate 17 reduces energy loss and improves conductivity and response performance. The stress buffer sheet 18 can absorb and disperse external forces, protecting the internal structure of the thin film component 2. The stable support component 4 ensures that each component is installed securely. The above is the working principle of this high-reliability superconducting sheet-type thin film switch.
