Description

Technical Field

[0001] This utility model relates to the field of electronic membrane switches, specifically an electronic membrane switch that prevents misalignment. Background Technology

[0002] As a new type of human-computer interaction component, the electronic membrane switch is a switching device that integrates functions such as buttons, panels, and circuits onto a single insulating film. It has advantages such as aesthetic appearance, good sealing, and long lifespan, and is widely used in many fields such as electronic equipment, home appliances, and automotive electronics, providing users with a convenient operating interface.

[0003] Electronic membrane switches typically achieve their control functions through circuit connections. When a user presses the button area on the membrane switch, the internal circuit of the switch will change from being on to being off. The electrical signal generated by this change will be transmitted to the connected control circuit, thereby triggering the corresponding device function.

[0004] However, in actual use, due to different operating habits and varying degrees of force applied by different personnel, when the pressure applied by the user is too great, the internal structure of the electronic membrane switch is easily subjected to excessive compression. This may cause the membrane layer to crack, the circuit connection parts to be damaged, and ultimately lead to damage to the internal structure of the electronic membrane switch, seriously affecting its normal performance and service life. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an electronic membrane switch that prevents misalignment, so as to solve the technical problem that the internal structure of the electronic membrane switch is easily damaged when the pressure applied by the operator is too great.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic membrane switch for preventing misalignment, comprising a switch body, wherein the switch body is provided with a surface plate, a first panel, an isolation plate, a second panel and a support plate respectively, a plurality of membrane springs are installed on the top of the first panel, a reinforcing block is provided inside the membrane springs, a plurality of connecting rods are connected to the bottom of the reinforcing block, a connecting post is provided at the end of the connecting rod, and a limiting ring is sleeved on the outer wall of the connecting post.

[0007] By adopting the above technical solution, the problem of damage to the internal structure of the electronic membrane switch caused by excessive pressure from personnel is solved. When the membrane spring deforms, it pushes the connecting post downward through the connecting rod, causing the connecting post to deform the first guide plate downward. During the displacement of the connecting post, the limiting ring limits the movement of the connecting post, ensuring that the connecting post can always move vertically. The limiting ring also limits the displacement distance of the connecting post, preventing the connecting post from squeezing and damaging the second guide plate due to excessive pressure from personnel.

[0008] The present invention is further configured such that a spring is sleeved on the outer wall of the connecting column, and a retaining ring is connected to the end of the spring.

[0009] Preferably, when a person presses down on the diaphragm spring, the diaphragm spring undergoes a certain deformation, and the spring buffers the deformation of the diaphragm spring through the connecting post, reducing metal fatigue caused by excessive deformation of the internal structure of the diaphragm spring.

[0010] The present invention is further configured such that the outer wall of the limiting ring is provided with multiple sets of fixing plates, and the fixing plates are located inside the surface plate.

[0011] Preferably, the fixing plate increases the contact area with the inside of the surface plate, so that the fixing plate can stably limit and fix the limiting ring, preventing the limiting post from shifting position during use.

[0012] The present invention is further configured such that a first wire plate is provided inside the first panel, a plurality of first guide plates are installed inside the first wire plate, and the first guide plates are fixed on the outer wall of the connecting column, and the first wire plate is connected to the positive terminal of the power supply.

[0013] Preferably, since the first wire board connected to one side of the first conductor is a power transmission board, the internal circuit of the switch body is in a closed state when the end of the connecting post contacts the surface of the second conductor.

[0014] The present invention is further configured such that the isolation plate is made of rubber and has insulating properties.

[0015] Preferably, the rubber isolation plate can deform to a certain extent with the switch body, and the isolation plate can isolate the current on the first and second wire plates.

[0016] The present invention is further configured such that a second line plate is provided inside the second panel, and multiple sets of second guide plates are installed inside the second line plate.

[0017] Preferably, when the bottom of the connecting post contacts the surface of the second conductor, current can flow between the first and second conductor plates through the connecting post.

[0018] The present invention is further configured such that a wire is connected to one side of the switch body, and a connecting end is installed at the end of the wire.

[0019] Preferably, the switch body is connected to the power supply via a connection terminal, which facilitates the disassembly and installation of the switch body by personnel.

[0020] The present invention is further provided that an adhesive plate is fixed to the bottom of the support plate, and the adhesive plate has a certain degree of adhesiveness.

[0021] Preferably, the switch body can be attached to the fixed panel using an adhesive plate, which facilitates the fixed installation of the switch body.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem that excessive pressure from personnel can easily damage the internal structure of electronic membrane switches by setting up a switch body, a membrane spring, a connecting rod, a connecting column, a limiting ring, and a fixing plate. When the membrane spring deforms, it pushes the connecting column downward through the connecting rod, causing the connecting column to deform the first guide plate downward. During the displacement of the connecting column, the limiting ring limits the movement of the connecting column, ensuring that the connecting column can always move vertically. The limiting ring also limits the displacement distance of the connecting column, preventing the connecting column from squeezing and damaging the second guide plate due to excessive pressure from personnel.

[0024] 2. This utility model, by setting up a thin film spring, a spring and a fixing ring, allows the thin film spring to deform to a certain extent when a person presses it down, and the spring buffers the deformation of the thin film spring through the connecting column, thereby reducing metal fatigue caused by excessive deformation of the internal structure of the thin film spring.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Please see Figure 1 — Figure 5 The switch body 1 includes a surface plate 4, a first panel 5, an isolation plate 6, a second panel 7, and a support plate 8. Multiple sets of membrane springs 3 are mounted on the top of the first panel 5. Reinforcing blocks 301 are installed inside the membrane springs 3. Multiple connecting rods 302 are connected to the bottom of the reinforcing blocks 301. Connecting posts 303 are installed at the ends of the connecting rods 302. Limiting rings 304 are fitted onto the outer walls of the connecting posts 303. This design solves the problem that excessive pressure from personnel can easily damage the internal structure of the electronic membrane switch. When the diaphragm spring 3 deforms, the diaphragm spring 3 pushes the connecting post 303 downward through the connecting rod 302, causing the connecting post 303 to deform the first guide plate 502 downward. During the displacement of the connecting post 303, the limiting ring 304 limits the movement of the connecting post 303, so that the connecting post 303 can always move in the vertical direction. The limiting ring 304 can limit the displacement distance of the connecting post 303 to prevent the connecting post 303 from squeezing and damaging the second guide plate 702 due to excessive pressure from personnel.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A spring 306 is sleeved on the outer wall of the connecting post 303. A fixing ring 307 is connected to the end of the spring 306. When the person presses down on the diaphragm spring 3, the diaphragm spring 3 will deform to a certain extent. The spring 306 buffers the deformation of the diaphragm spring 3 through the connecting post 303, reducing metal fatigue caused by excessive deformation of the internal structure of the diaphragm spring 3.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 5The outer wall of the limiting ring 304 is provided with multiple sets of fixing plates 305, and the fixing plates 305 are located inside the surface plate 4. By increasing the contact area with the inside of the surface plate 4, the fixing plates 305 can stably limit and fix the limiting ring 304, preventing the limiting post 304 from shifting position during use.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5 The first panel 5 has a first wire plate 501 inside. Multiple sets of first guide plates 502 are installed inside the first wire plate 501. The first guide plates 502 are fixed on the outer wall of the connecting post 303. The first wire plate 501 is connected to the positive terminal of the power supply. Since the first wire plate 501 connected to one side of the first guide plate 502 is a power transmission board, when the end of the connecting post 303 contacts the surface of the second guide plate 702, the internal circuit of the switch body 1 is in a closed state.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The isolation plate 6 is made of rubber and has insulating properties. The rubber isolation plate 6 can deform to a certain extent with the switch body 1, and the isolation plate 6 can isolate the current on the first wire plate 501 and the second wire plate 701.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The second panel 7 has a second wire plate 701 inside, and multiple sets of second guide plates 702 are installed inside the second wire plate 701. When the bottom of the connecting post 303 contacts the surface of the second guide plate 702, the current between the first wire plate 501 and the second wire plate 701 can flow through the connecting post 303.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A wire 201 is connected to one side of the switch body 1, and a connector 2 is installed at the end of the wire 201. The switch body 1 is connected to the power supply through the connector 2, which facilitates the disassembly and installation of the switch body 1 by personnel.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 An adhesive plate 801 is fixed to the bottom of the support plate 8, and the adhesive plate 801 has a certain degree of adhesiveness. Personnel can attach the switch body 1 to the fixed panel through the adhesive plate 801, which makes it convenient for personnel to fix and install the switch body 1.

[0042] In practical operation, the following steps are taken: When a person presses down on the diaphragm spring 3, the diaphragm spring 3 deforms. The diaphragm spring 3 pushes the connecting post 303 downward through the connecting rod 302, causing the connecting post 303 to deform the first guide plate 502 downward until the end of the connecting post 303 contacts the top surface of the second guide plate 702. During the downward movement of the connecting post 303, the connecting post 303 stretches the spring 306 through the fixing ring 307. Since the first wire plate 501 connected to one side of the first guide plate 502 is a power transmission board, when the end of the connecting post 303 contacts the surface of the second guide plate 702, the internal circuit of the switch body 1 is in a closed state. When the external pressure on the diaphragm spring 3 disappears, the spring 306 drives the connecting post 303 to reset through the fixing ring 307. The connecting post 303 presses the diaphragm spring 3 upward, so that the diaphragm spring 3 returns to its initial state.
