Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a metal spring anti-deformation tactile switch. Background Technology

[0002] Tactile switches, also known as push-button switches, have become increasingly popular due to technological advancements and advancements in technology. They are widely used in electronic devices and white goods because of their advantages, including low contact resistance, precise operating force, and diverse specifications. Also called micro switches, they are activated by gently pressing a button; their internal structure relies on a metal spring that springs together to control the circuit. Micro switches are widely used in household appliances due to their small size and light weight, and can also be used to control low-power appliances such as lighting fixtures and exhaust fans.

[0003] In recent years, tactile switches have seen rapid development in the home decoration field, frequently used in household lighting, sockets, and other applications. When used in the home, tactile switches often require light indicators. However, due to their internal structure, typical tactile switches tend to block light, necessitating the placement of small LEDs near the button to illuminate the photolithographic markings. This is problematic because the electrical area of ​​a tactile switch is already very compact, making it difficult to allocate additional space for small LEDs. This would also affect the layout of the circuit board. Furthermore, the illumination angle of these small LEDs is often less than ideal, resulting in excessive glare at night and an uneven, unpleasant glow. Additionally, the automatic rebound of existing tactile switches makes it difficult to determine their open / closed state, causing inconvenience and reducing the user experience. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal spring anti-deformation tactile switch.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a metal spring anti-transformation type tactile switch, including a mounting frame, the mounting frame fixing multiple switch electrical groups, each switch electrical group including a switch display panel, each switch electrical group including a switch insulating frame, the switch display panel including multiple rear electrode plates, the rear electrode plates being electrically connected to each other, multiple ink storage capsules fixed on one side of each rear electrode plate, each ink storage capsule containing relay fluid and multiple charged black particles, a front electrode plate fixed on one side of each ink storage capsule, a transparent glass plate fixed on one side of the front electrode plate, an eye-protecting light strip fixed on the side of the transparent glass plate, a plate frame fixed on one side of the eye-protecting light strip, a rotating rod fixed on the top of the plate frame, both ends of the rotating rod being fixed to the inner wall of the switch insulating frame, a rubber contact pad fixed on one side of the plate frame, and a reset pressure column fixed at the bottom of the plate frame. In the prior art, tactile switches have developed rapidly in the home decoration field in recent years and are often used in home lighting, sockets, etc. When used in the home, tactile switches often need to have light indicators. Conventional tactile switches, due to their internal structure which easily blocks light, typically require placing small LEDs near the rubber button to illuminate the photolithographic markings. However, many electrical appliances using tactile switches have very compact spaces, making it difficult to allocate additional space for small LEDs, which would affect the circuit board layout. Furthermore, the illumination angle of these small LEDs is often unsatisfactory, resulting in excessive glare at night and an uneven, unpleasant glow. Additionally, the automatic rebound of existing tactile switches makes it difficult to determine their open / closed state, causing inconvenience and a poor user experience. To address these issues, this invention solves the problem by installing a switch display board within the switch's electrical assembly. This allows charged black particles to display text or images on the front electrode plate through control of the electrode plate, similar to printing a document. During the day, it produces diffuse reflection, eliminating the need for artificial lighting and preventing glare. Users can clearly see the switch display panel from any angle in their home. At night, it emits light through an eye-protecting light strip. The light is repeatedly refracted within the transparent glass panel, illuminating the front electrode panel and allowing users to clearly see the text displayed on the switch display panel. The light is not direct; it is diffused light with a small illumination range, so even if installed in a bedroom, it will not disturb the user's rest. Users can control the rear and front electrode panels using their mobile phones to set different text or graphic representations of the open / closed states, making it easier for users to determine the open / closed status. This improves user experience, ease of use, and efficiency.

[0006] Preferably, the inner wall of the switch insulation frame is fixed with multiple electrical feet, the top of the electrical feet is fixed with a contact frame, the inner wall of the contact frame is fixed with a copper tab, and the top of the contact frame is fixed with a metal spring. The surface of the metal spring has multiple multi-level grooves. In the prior art, tactile switches rely on the toughness of the metal spring for opening, closing, and resetting. However, during prolonged use, the continuous deformation of the metal spring reduces its elasticity, thus reducing its lifespan and consequently the effectiveness of the tactile switch. Furthermore, the existing tactile switches have metal springs and copper tabs... The contact time of the tactile spring is relatively short and the contact range is relatively narrow, which reduces the sensitivity of the tactile switch and easily leads to poor contact. To address this problem, this invention solves the issue by creating multiple multi-level grooves on the surface of the metal spring. This reduces the deformation volume of the metal spring, and the dislocation density of the sliding metal spring with multiple multi-level grooves is significantly reduced compared to the unremoved dislocation. This allows the potential energy accumulated by the elastic deformation of the metal spring to drive only a smaller deformation volume, reducing the possibility of plastic deformation of the metal spring, thereby improving the service life of the equipment and preventing deformation of the metal spring.

[0007] Preferably, a tactile reset button is fixed to the bottom of the switch insulating frame. A keyway groove is formed on one side of the tactile reset button, and a spring is provided on the inner wall of the keyway groove. One end of the spring is fixed to the inner wall of the keyway groove, and the other end of the spring is fixed to one end of the reset pressure post. The reset pressure post is slidably connected to the inner wall of the keyway groove. Multiple limiting members are fixed to the bottom of the switch insulating frame. A limiting arc groove is formed on the top of the limiting member, and the surface of the limiting arc groove is slidably connected to the bottom of the switch display panel. In the prior art, the elastic deformation of the metal spring has a certain range. The number of elastic deformations within a certain range also reflects different fatigue levels depending on the magnitude of the elastic deformation. When the elastic deformation amplitude is large, the metal spring is more prone to fatigue, causing damage and breakage of the metal spring, reducing the product's service life. To address this problem, this utility model solves the problem by installing a tactile reset button and limiting members. This achieves the combination of the tactile reset button and limiting members, limiting the swing range of the switch display panel, reducing the elastic deformation amplitude of the metal spring, increasing its fatigue strength, and automatically resetting after being pressed by the user, thereby improving the user experience and extending the product's service life.

[0008] Preferably, the inner wall of the switch insulation frame is fixed with multiple sealing gaskets. Some users touch the switch when their hands are wet. By fixing the sealing gaskets, the waterproof effect of the switch is improved, and users are prevented from being electrocuted.

[0009] Preferably, the surface of the switch insulation frame is wrapped with a rubber layer. The rubber layer improves the insulation effect of the switch insulation frame and prevents the metal casing from becoming electrified.

[0010] Preferably, the mounting frame has multiple label slots on one side to facilitate users to attach labels to distinguish the purpose of the switch.

[0011] Preferably, the metal spring is made of aluminum alloy. Aluminum alloy has a specific strength close to that of high alloy steel, a specific stiffness exceeding that of steel, good electrical and thermal conductivity, good corrosion resistance and weldability, and high toughness, which can withstand large deformations without breaking, thereby improving the service life of the product.

[0012] Beneficial effects

[0013] 1. In the existing technology, tactile switches have developed rapidly in the home decoration field in recent years and are often used in household lighting, sockets, etc. When used in the home, tactile switches often need to have light indicators. Ordinary tactile switches, due to their internal structure, easily block light, so small LEDs are usually placed separately near the rubber button to illuminate the photolithographic markings on the button. However, many electrical appliances using tactile switches have very compact spaces, making it difficult to allocate additional space for small LEDs, which would affect the structural layout of the circuit board. Furthermore, the illumination angle of ordinary small LEDs is generally not ideal, being very glaring at night, and the brightness effect is not soft and uniform enough. In addition, existing tactile switches automatically rebound, making it difficult to determine their open / closed state, causing inconvenience to users and reducing the user experience. To address these problems, this utility model solves the issue by installing a switch display board on the switch's electrical assembly. This allows for the display of text or images on the front electrode plate by controlling the electrode plate, with characteristics similar to printing documents. During the day, it produces diffuse reflection, eliminating the need for artificial lighting and preventing glare. Users can clearly see the switch display panel from any angle in their home. At night, it emits light through an eye-protecting light strip. The light is repeatedly refracted within the transparent glass panel, illuminating the front electrode panel and allowing users to clearly see the text displayed on the switch display panel. The light is not direct; it is diffused light with a small illumination range, so even if installed in a bedroom, it will not disturb the user's rest. Users can control the rear and front electrode panels using their mobile phones to set different text or graphic representations of the open / closed states, making it easier for users to determine the open / closed status. This improves user experience, ease of use, and efficiency.

[0014] 2. In existing technologies, tactile switches rely on the toughness of a metal spring for opening, closing, and resetting. However, during prolonged use, the continuous deformation of the metal spring reduces its elasticity, thus shortening its lifespan and reducing the effectiveness of the tactile switch. Furthermore, the contact time between the metal spring and the copper contact plate in existing tactile switches is relatively short and the contact area is narrow, reducing the sensitivity of the tactile switch and making it prone to poor contact. To address these issues, this invention solves the problem by creating multiple multi-level grooves on the surface of the metal spring. This reduces the deformation volume of the metal spring, and the dislocation density of the sliding metal spring with multiple grooves is significantly reduced compared to the ungrown type. This allows the potential energy accumulated by the elastic deformation of the metal spring to drive a smaller deformation volume, reducing the possibility of plastic deformation of the metal spring, thereby improving the service life of the device and preventing deformation of the metal spring.

[0015] 3. In the prior art, the elastic deformation of the metal spring has a certain range. Within this range, the number of elastic deformations varies with the magnitude of the elastic deformation, resulting in different levels of fatigue. When the elastic deformation amplitude is large, the metal spring is more prone to fatigue, leading to damage and breakage, and reducing the product's service life. To address this problem, this utility model solves it by installing a touch-sensitive reset button and a limiting component. This combination of the touch-sensitive reset button and the limiting component restricts the swing range of the switch display panel, reduces the elastic deformation amplitude of the metal spring, increases its fatigue strength, and automatically resets it after the user presses it, thereby improving the user experience and extending the product's service life.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6A metal spring-loaded anti-transformation tactile switch includes a mounting frame 1. Multiple switch electrical groups 2 are fixed to the mounting frame 1. Each switch electrical group 2 includes a switch display panel 3 and a switch insulating frame 201. The switch display panel 3 includes multiple rear electrode plates 301, which are electrically connected to each other. Multiple ink storage capsules 303 are fixed to one side of each rear electrode plate 301. Each ink storage capsule 303 contains a relay fluid 304 and multiple charged black particles 305. A front electrode plate 302 is fixed to one side of each ink storage capsule 303. A transparent glass plate 306 is fixed to one side of the electrode plate 302. An eye-protecting light strip 308 is fixed to the side of the transparent glass plate 306. A plate frame 307 is fixed to one side of the eye-protecting light strip 308. A rotating rod 4 is fixed to the top of the plate frame 307. Both ends of the rotating rod 4 are fixed to the inner wall of the switch insulation frame 201. A rubber contact pad 402 is fixed to one side of the plate frame 307. A reset pressure post 403 is fixed to the bottom of the plate frame 307. Tactile switches have developed rapidly in the home decoration field in recent years and are often used in home lighting, sockets, etc. When used in the home, tactile switches often need to have light indicators. Because the internal structure of ordinary tactile switches easily blocks light, the small light beads are usually arranged separately near the rubber button so that the light can illuminate the photolithographic markings on the button. However, many electrical appliances using tactile switches have very compact spaces, making it difficult to allocate additional space for small LEDs. This would affect the structural layout of the circuit board. Furthermore, the illumination angle of small LEDs is generally not ideal, resulting in excessive glare at night and an uneven, unpleasant glow. Additionally, existing tactile switches automatically rebound, making it difficult to determine their open / closed state, causing inconvenience and reducing user experience. This problem is solved by installing a switch display board 3 on the switch electrical group 2. This allows the charged black particles 305 to display text or images on the front electrode plate 302 through control of the electrode plate. Its characteristics are similar to printed documents, producing diffuse reflection during the day, eliminating the need for... The light is turned on without causing glare, and the switch display panel 3 can be clearly seen from any angle in the home. At night, the light emitted by the eye-protection light strip 308 is repeatedly refracted in the transparent glass plate 306, illuminating the front electrode plate 302 so that the user can clearly see the text display on the switch display panel 3. Moreover, the light is not direct light, but diffused light with a small illumination range. Even if installed in the bedroom, it will not affect the user's rest. The user can use a mobile phone to control the rear electrode plate 301 and the front electrode plate 302 to set different text or graphic representations of the open and closed states, making it easier for the user to judge the open and closed state, thereby improving the user experience, making it easier for the user to use, and increasing the efficiency of use.Multiple electrical feet 202 are fixed to the inner wall of the switch insulation frame 201. A contact frame 203 is fixed to the top of the electrical feet 202. A copper tab 204 is fixed to the inner wall of the contact frame 203. A metal spring 205 is fixed to the top of the contact frame 203. Multiple multi-level slots 206 are formed on the surface of the metal spring 205. The tactile switch relies on the toughness of the metal spring 205 to open, close, and reset the switch. However, during long-term use, the continuous deformation of the metal spring 205 reduces its elasticity, thereby reducing its service life and the effectiveness of the tactile switch. Furthermore, the existing tactile switch internal metal spring 205... The contact time between 05 and the copper contactor 204 is relatively short and the contact range is relatively narrow, which reduces the sensitivity of the tactile switch and makes it prone to poor contact. This problem is solved by creating multiple multi-level grooves 206 on the surface of the metal contact 205. This reduces the deformation volume of the metal contact 205. The dislocation density of the slipped metal contact 205 with multiple multi-level grooves 206 is greatly reduced compared to the uncut one. This means that the potential energy accumulated by the elastic deformation of the metal contact 205 only needs to drive a smaller deformation volume, reducing the possibility of plastic deformation of the metal contact 205, thereby improving the service life of the equipment and preventing deformation of the metal contact 205.

[0028] Multiple sealing gaskets 408 are fixed to the inner wall of the switch insulation frame 201. Some users may touch the switch with wet hands; fixing the sealing gaskets 408 improves the switch's waterproof effect and prevents electric shock. The surface of the switch insulation frame 201 is covered with a rubber layer, which enhances the insulation effect and prevents the metal casing from becoming electrified. Multiple label slots 101 are provided on one side of the mounting frame 1 for users to attach labels to distinguish the switch's purpose. The metal spring 205 is made of aluminum alloy. Aluminum alloy has a specific strength close to that of high-alloy steel and a specific stiffness exceeding that of steel. It has good electrical and thermal conductivity, good corrosion resistance and weldability. The high toughness of aluminum alloy allows it to withstand significant deformation without breaking, thus extending the product's lifespan. A tactile reset button 401 is fixed to the bottom of the switch insulating frame 201. A keyway groove 404 is formed on one side of the tactile reset button 401. A spring 405 is provided on the inner wall of the keyway groove 404. One end of the spring 405 is fixed to the inner wall of the keyway groove 404, and the other end of the spring 405 is fixed to one end of the reset pressure post 403. The reset pressure post 403 is slidably connected to the inner wall of the keyway groove 404. Multiple limiting members 406 are fixed to the bottom of the switch insulating frame 201. A limiting arc groove 407 is formed on the top of the limiting member 406. The surface of the limiting arc groove 407 is slidably connected to the bottom of the switch display panel 3. The elastic deformation of the metal spring 205 has a certain range. Within a certain range, the number of elastic deformations also reflects different fatigue levels depending on the magnitude of the elastic deformation. When the elastic deformation amplitude is large, the metal spring 205 is more prone to fatigue, causing damage and breakage of the metal spring 205 and reducing the product's service life. This is solved by installing a touch reset button 401 and a limiting component 406. This achieves the cooperation between the touch reset button 401 and the limiting component 406, limiting the swing range of the switch display panel 3, reducing the elastic deformation amplitude of the metal spring 205, increasing its fatigue strength, and automatically resetting after being pressed by the user, thereby improving the user experience and extending the product's service life.

[0029] The working principle of this utility model is as follows: After the installation frame 1 is installed on the wall, the user can use a mobile phone to set different text or graphic representations of the open / closed state of the switch display panel 3, making it easy for the user to judge its open / closed state. The switch display panel 3 controls the electrode plate, causing the charged black particles 305 to display text or pictures on the front electrode plate 302. When the user presses the switch display panel 3, the switch display panel 3 rotates around the rotating rod 4, and the reset pressure column 403 presses the spring 405 on the inner wall of the keyway groove 404. The bottom of the switch display panel 3 is in a limiting position. The surface of the arc groove 407 slides, and the rubber contact pad 402 presses the metal spring 205, causing the metal spring 205 to deform elastically. When the metal spring 205 contacts the copper lever 204, the switch is energized. At the same time, the keyway 404 and the limiting member 406 limit the switch display panel 3 from continuing to rotate, so as to prevent the metal spring 205 from deforming too much. After the user releases the hand, the elastic potential energy accumulated by the metal spring 205 and the spring 405 is released, causing the switch display panel 3 to rotate in the opposite direction until it is reset. The switch display panel 3 is limited by the limiting member 406 to prevent it from being over-reset and falling off.
