Description

Technical Field

[0001] This invention relates to the field of electronic components technology, specifically to a multi-chip gold-plated fitted irregular-shaped tactile switch structure. Background Technology

[0002] To accommodate the aesthetics and ergonomic grip of electronic devices such as smart rings, smart gloves, health monitoring bracelets, or ergonomic handles, the surfaces are typically curved, tilted, or irregularly shaped. This necessitates that the internal switches and buttons also be designed to fit the irregular shape of the casing. Furthermore, users require the switches to provide crisp and clear feedback when pressed and released to confirm that the operation has been accurately completed.

[0003] Because users' finger pressing habits, positions, and angles vary each time, the force on the button is often not vertically downward. When the switch is subjected to a downward pressing force, it cannot convert this inclined force into a trigger force in the predetermined direction. This causes the internal components to tilt to one side and become stuck when the button is pressed at an angle, weakening or even significantly reducing the crisp pressing feel. Furthermore, it often happens that although the button is pressed all the way down, the internal circuit is not actually connected. A common solution is to place a circular or cross-shaped metal spring directly under the irregularly shaped button. When the user presses the button at an angle, the downward protrusion at the bottom of the button will deviate from the highest point of the center of the metal spring and act directly on the offset position of the spring. This long-term uneven force will directly cause the metal spring to flip and shift to one side, and cause permanent collapse and deformation of the edge of the spring. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-plate gold-plated fitted irregular tactile switch structure to solve the problem mentioned in the background art where the crisp pressing sensation of irregular tactile switches weakens or even significantly diminishes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-piece gold-plated fitting irregular tactile switch structure, comprising a base, a conducting component, a sealing component, and a guiding component, wherein the conducting component comprises a spring body and a first column disposed on the base; The sealing assembly includes a second elastic element and a second ring body disposed on the base; The guide assembly includes a third ring body disposed on the base, and a sphere is disposed above the third ring body; Let the direction in which the sphere is compressed and approaches the base be the first direction, let the direction in which the spring sheet approaches the first column be the second direction, and let the direction in which the first column approaches the base be the third direction; When the sphere is pressed along the first direction, it pushes the second ring to move. The second ring pushes the spring to hug the first column along the second direction, and the first column continues to move along the third direction.

[0006] Preferably, the base has a groove, the first column is slidably disposed in the groove, the base has a first elastic element, the first elastic element supports the first column, and the first column compresses the first elastic element when it moves in a third direction.

[0007] Preferably, the base is provided with a first ring body, the spring body is disposed on the first ring body, the spring body is electrically connected to the first ring body, the first column is electrically connected to one contact of an external circuit through a first elastic element, and the spring body is electrically connected to another contact of an external circuit through the first ring body.

[0008] Preferably, the spring body has an outwardly convex curved section that protrudes away from the first column, and the second ring body is provided with a first inclined surface. The first inclined surface abuts against the outwardly convex curved section. When the second ring body moves in the first direction, the first inclined surface pushes the spring body to move in the second direction.

[0009] Preferably, the second elastic element is disposed between the groove and the second ring. When the second ring moves along the first direction, it compresses the second elastic element. After the ball loses the pressing force, the second elastic element pushes the second ring away from the base to reset.

[0010] Preferably, the second ring body has a second inclined surface on its outer side, and a third elastic member is sleeved on the outer side of the second ring body. The third elastic member has a third inclined surface, and the third inclined surface abuts against the second inclined surface. When the second ring body moves along the first direction, the second inclined surface pushes the third elastic member to expand towards the edge of the base.

[0011] Preferably, the bottom of the sphere is provided with a second column, which passes through the third ring body. The third ring body is provided with a ball bearing, which abuts against the outer wall of the second column. When the second column moves in the first direction, it maintains its direction of movement through the ball bearing.

[0012] Preferably, the sphere is provided with a keycap, and the keycap is provided with a hemispherical groove that slides with the sphere. When the keycap is subjected to tilting pressure, it deflects relative to the sphere, and the sphere pushes the second ring body along the first direction.

[0013] Preferably, the bottom of the sphere is provided with a second column, the second column is provided with an annular pressing surface that presses against the second ring, and the second column is provided with a downward pressing part facing the first column. The annular pressing surface first pushes the second ring to move, so that the spring body hugs the first column, and the downward pressing part then pushes the first column to move in a third direction.

[0014] A triggering method for a multi-chip gold-plated fitted irregular tactile switch structure includes the following steps: Press the sphere to bring it closer to the base along the first direction; The sphere pushes the second ring to move, and the second ring pushes the spring body to move closer to the first column along the second direction; The spring clip body hugs the first column, so that the spring clip body and the first column form a conductive contact; Continue pressing the sphere, and the first column moves closer to the base along a third direction, sliding relative to the spring sheet; When the pressure on the sphere is released, the second ring body returns to its original position, the spring piece disengages from the first column, and the first column returns to its original position.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the ball is pressed, it can transmit the pressing force from the external irregular button to the base. The guide component restricts the movement of the ball and the pressing structure, so that the tilting pressing force is not easily applied directly to the bias position of the spring body, reducing the situation of the spring body overturning, displacement and local collapse deformation caused by the force bias. When the ball is pressed along the first direction, it pushes the second ring to move. The second ring then pushes the spring body along the second direction to approach and hug the first column, so that the spring body forms a multi-point fitting contact on the outside of the first column, increasing the conductive contact area and contact pressure, and improving the problem that the spring body cannot stably press the contact point when the traditional irregular button is pressed downward at an angle, resulting in a false connection. 2. After the spring-loaded body grips the first column, the first column continues to move towards the base along a third direction, causing relative sliding between the first column and the spring-loaded body. This allows for scraping and cleaning of deposits on the contact surface, reducing the impact of contaminants and particles on the conductive contact. The second elastic element provides support and reset for the second ring, enabling the second ring to release the spring-loaded body from the first column after the press is released. The first column then resets synchronously, and the switch returns from the on state to the off state. This allows the switch to adapt to irregular pressing conditions formed by bent, tilted, or irregular shells, ensuring that the button maintains a smooth pressing path, noticeable pressing feedback, and stable circuit conduction even when it is tilted and pressed.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Please see Figure 1 As shown, a multi-piece gold-plated fitted irregular tactile switch structure includes a base 1, a conducting component 2, a sealing component 3, and a guiding component 4.

[0020] It should be noted that, in combination Figure 2 and Figure 3 As shown, this switch structure is vertically mounted above the circuit board of the external device. The keycap 43 is placed at the opening of the outer casing of the external device. The top curved surface of the keycap 43 is flush with the curved surface of the outer casing of the external device. The bottom end of the base 1 is fixed on the circuit board.

[0021] like Figure 4 and Figure 5 As shown, the base 1 is preferably made of insulating plastic material, and the top end of the base 1 is recessed downward to form a groove 22, which extends along the height direction of the base 1.

[0022] like Figure 1 and Figure 4As shown, the conductive component 2 is disposed in the central region of the base 1, as... Figures 6 to 8 As shown, the conductive component 2 includes a first ring body 21, which is preferably made of conductive metal. The first ring body 21 is fixed on the top end face of the base 1 inside the groove 22. The first ring body 21 is electrically connected to the contacts of the circuit board through conductive terminals. The conductive component 2 also includes multiple spring pieces 23, which are preferably made of gold-plated metal sheets. The bottom end of each spring piece 23 is fixed inside the first ring body 21. The bottom end of the spring piece 23 is electrically connected to the first ring body 21. The multiple spring pieces 23 are spaced apart around the groove 22. The spring pieces 23 are curved and protrude away from the center of the groove 22.

[0023] like Figures 6 to 8 As shown, each spring body 23 includes a fixed section, an outwardly convex bending section and a contact section. The fixed section is connected to the first ring body 21. The outwardly convex bending section is located above the fixed section. The contact section is located above the outwardly convex bending section and faces the first column 25. The outwardly convex bending section is used to slide and engage with the first inclined surface 321 of the second ring body 32. The contact section is used to abut against the outer wall of the first column 25 after the spring body 23 is retracted inward.

[0024] like Figure 4 and Figure 7 As shown, the conductive component 2 also includes a first elastic element 24, which is a helical compression spring. The first elastic element 24 is preferably made of conductive metal. The first elastic element 24 is placed inside the base 1. The bottom end of the first elastic element 24 is electrically connected to the contacts of the circuit board. The conductive component 2 also includes a first column 25. The top end of the first elastic element 24 supports the first column 25. The first column 25 is preferably made of gold-plated metal. The bottom surface of the first column 25 presses against the top end of the first elastic element 24. The outer wall of the first column 25 slides against the inner wall of the base 1. The first column 25 can move downward and compress the first elastic element 24.

[0025] When using, combine Figures 4 to 7 The first column 25 is electrically connected to the contacts of the circuit board through the first elastic element 24, and the spring body 23 is electrically connected to the contacts of the circuit board through the first ring body 21. When the contact section of the spring body 23 hugs the first column 25 inward, the two contacts are connected through the first ring body 21, the spring body 23, the first column 25 and the first elastic element 24. When the spring body 23 leaves the first column 25, the connection between the two contacts is broken.

[0026] like Figures 6 to 8As shown, the sealing assembly 3 has an expanded state and a contracted state. The sealing assembly 3 includes a second elastic element 31, which is a helical compression spring. The second elastic element 31 is placed in the groove 22 and surrounds multiple spring pieces 23. The sealing assembly 3 also includes a second ring 32, which is preferably made of insulating plastic. The bottom surface of the second ring 32 presses against the top surface of the second elastic element 31. The second ring 32 can move relative to the base 1 in the height direction. The inner wall of the hole 2 is inclined to form a first inclined surface 321. The inner diameter of the first inclined surface 321 gradually decreases along the direction close to the bottom of the base 1. The first inclined surface 321 is attached to the outwardly protruding surface of the spring body 23. When the second ring body 32 moves downward, the first inclined surface 321 slides along the outwardly convex curved section of the spring body 23 and pushes the spring body 23 to converge towards the center of the groove 22. The outer wall of the second ring body 32 is inclined to form a second inclined surface 322. The outer diameter of the second inclined surface 322 gradually increases along the direction close to the bottom of the base 1.

[0027] like Figures 6 to 8 As shown, the sealing assembly 3 also includes a third elastic element 33, which is preferably made of silicone. The third elastic element 33 is sleeved on the outside of the second ring 32. The inner wall of the third elastic element 33 is inclined to form a third inclined surface 331. The third inclined surface 331 fits against the second inclined surface 322. The outer wall of the third elastic element 33 is a cylindrical surface. The bottom end of the third elastic element 33 is fixed on the annular support surface of the base 1. The top end of the third elastic element 33 is limited by the limiting flange on the inner side of the base 1. The third elastic element 33 is limited in the height direction. The third elastic element 33 can expand radially outward under the compression of the second inclined surface 322.

[0028] When using, combine with, for example Figures 6 to 8 As shown, when the second ring 32 is subjected to a downward thrust, the second inclined surface 322 slides downward relative to the third inclined surface 331. Since the third elastic element 33 is restricted in the height direction, the third elastic element 33 cannot move downward with the second ring 32 as a whole. The second inclined surface 322 applies an outward thrust to the third inclined surface 331, causing the third elastic element 33 to expand towards the annular baffle of the base 1. When the third elastic element 33 expands to its limit position, the outer wall of the third elastic element 33 fits against the inner side of the annular baffle of the base 1. The third elastic element 33 seals the annular gap between the outer side of the second column 421 and the annular baffle of the base 1, which is used to prevent dust entering from the housing opening from continuing to enter the area where the conductive component 2 is located.

[0029] like Figures 7 to 9As shown, the guide component 4 can work in conjunction with the sealing component 3. When the guide component 4 is pressed down, the sealing component 3 is in an expanded state. When the guide component 4 is reset and raised, the sealing component 3 is reset and contracted. The guide component 4 includes a third ring body 41, which is preferably made of thin-walled metal. The third ring body 41 is fixed to the inner side of the annular baffle of the base 1. The third ring body 41 is located above the third elastic member 33. There is a movable gap between the lower end of the third ring body 41 and the upper end of the third elastic member 33. When the third elastic member 33 expands outward, it does not interfere with the third ring body 41.

[0030] like Figures 7 to 9 As shown, the inner wall of the third ring 41 accommodates a plurality of balls 411, which are preferably made of stainless steel. The balls 411 can roll within the third ring 41, with a portion of each ball extending out of the inner wall of the third ring 41 and facing the center of the third ring 41. The guide assembly 4 also includes a ball 42, the bottom of which is fixedly connected to a second column 421. The outer side wall of the second column 421 is inserted into the third ring 41, and the outer side wall of the second column 421 makes rolling contact with the balls 411. The bottom outer periphery of the second column 421 forms an annular pressing surface, which presses against the top surface of the second ring 32. The bottom center of the second column 421 forms a downward pressing part, which is opposite to the top surface of the first column 25. The bottom surface of the pressing part is higher than the annular pressing surface. The annular pressing surface first pushes the second ring 32 down. After the second ring 32 moves down to the point where the spring body 23 hugs the first column 25, the pressing part then touches the top surface of the first column 25 and pushes the first column 25 into the groove 22.

[0031] like Figure 2 , Figure 3 and Figure 9 As shown, the guide assembly 4 also includes a keycap 43, which is preferably made of plastic. The keycap 43 covers the top of the ball 42. The bottom center of the keycap 43 is concave upward to form a hemispherical groove. The hemispherical groove of the keycap 43 and the ball 42 form a spherical sliding fit. The keycap 43 can tilt relative to the ball 42. There is a gap between the outer edge of the keycap 43 and the opening of the external device housing, so that the keycap 43 can tilt slightly when subjected to tilting pressure.

[0032] When using, combine Figure 7 and Figure 9The keycap 43 and the ball 42 maintain a spherical sliding fit. When an external pressing force is applied to the keycap 43 at an angle, the keycap 43 tilts relative to the ball 42. The lateral component of the pressing force is absorbed by the spherical fit between the keycap 43 and the ball 42. The second column 421 moves downward along the height direction under the restriction of the third ring 41 and the ball 411. The ball 411 makes rolling contact with the second column 421 to reduce the friction between the second column 421 and the third ring 41 and reduce the risk of jamming when the second column 421 moves downward.

[0033] It should be noted that the spring body 23 undergoes elastic bending during the compression process. When the second ring body 32 moves down to the highest point of the protrusion of the first inclined surface 321, the spring body 23 changes from an outwardly convex bending state to a bending state that converges towards the first column body 25. This change creates a pressing segment sensation.

[0034] First linkage state, combined with Figures 6 to 9 Before the circuit is established, the annular pressing surface of the second column 421 pushes the second ring 32 downward. The second ring 32 causes the first inclined surface 321 to descend, making the first inclined surface 321 slide into contact with the outwardly convex curved section of the spring body 23. As the second ring 32 continues to move downward, the first inclined surface 321 pushes the spring body 23 towards the center of the groove 22. The spring body 23 slowly bends towards the first column 25, and the contact section of the spring body 23 gradually abuts against the outer wall of the first column 25. As the downward movement of the second ring 32 increases, the clamping force of the spring body 23 on the first column 25 increases. The spring body 23 makes the two contacts of the circuit board conduct through the first column 25 and the first elastic element 24. This clamping relationship is used to limit the first column 25 from deviating from the conduction contact range and reduce incomplete connections.

[0035] The second linkage state, combined with Figure 4 , Figures 7 to 9 After the second ring 32 moves down into position, the pressing part of the second column 421 abuts against the top surface of the first column 25. As the second column 421 continues to move downward, the first column 25 enters the base 1 along the groove 22. The first column 25 simultaneously compresses the first elastic element 24. Since the spring sheet 23 has already hugged the first column 25, relative sliding occurs between the first column 25 and the spring sheet 23 when the first column 25 moves down. The spring sheet 23 scrapes and cleans the surface deposits on the outer wall of the first column 25 to reduce the isolation effect of the contamination film and particles on the conductive contact surface. The first column 25 moves downward vertically, and multiple spring sheets 23 are arranged around the first column 25. During the downward movement of the first column 25, it can maintain continuous contact with multiple spring sheets 23, thereby improving the conductivity stability.

[0036] The third linkage state, combined with Figures 6 to 9When the second ring 32 moves downward, the second inclined surface 322 moves downward synchronously. As the outer diameter of the second inclined surface 322 gradually increases along the direction close to the bottom of the base 1, the second inclined surface 322 applies an outward pushing force to the third inclined surface 331 of the third elastic member 33, causing the third elastic member 33 to expand towards the annular wall of the base 1. After the outer wall of the third elastic member 33 fits against the annular wall of the base 1, the annular gap between the outer side of the second column 421 and the annular wall of the base 1 is closed, and external dust cannot easily enter the area where the spring body 23 and the first column 25 are located through the annular gap. When the second ring 32 continues to move downward, the second elastic member 31 is compressed. The second elastic member 31 is used to push the second ring 32 to reset after the external pressing pressure is released.

[0037] The working principle of this embodiment is as follows: During the preparation phase, the mechanism is fixed above the adapter circuit board, and then... Figures 1 to 3 The outer casing of the external device is installed above the base 1, the keycap 43 is placed at the opening of the casing, the bottom of the base 1 is fixed to the circuit board, the first ring 21 is electrically connected to the first contact of the circuit board, the first elastic element 24 is electrically connected to the second contact of the circuit board, the spring body 23 and the first column 25 are in a separated or slightly close state, and the circuit is in an open state. During the pressure-guided phase, combined with Figures 7 to 9 External pressing force is applied to keycap 43. Keycap 43 slides relative to ball 42 through hemispherical groove. Ball 42 transmits downward pressing force to second column 421. Under the guidance of third ring 41 and ball 411, second column 421 moves downward along the height direction. The annular pressing surface of second column 421 first presses the second ring 32. Second ring 32 moves downward along the height direction of base 1. During the sealing and clamping phase, combined Figures 6 to 9 When the second ring 32 moves downward, the first inclined surface 321 on the inner side of the second ring 32 pushes the spring piece 23 to retract towards the first column 25. The contact section of the spring piece 23 abuts against and hugs the first column 25, so that the first ring 21, the spring piece 23, the first column 25 and the first elastic member 24 form a conductive link. The second inclined surface 322 on the outer side of the second ring 32 simultaneously squeezes the third inclined surface 331 of the third elastic member 33. The third elastic member 33 expands outward and fits against the annular baffle of the base 1, blocking dust from continuing to enter the area where the conductive component 2 is located. During this process, the second ring 32 simultaneously compresses the second elastic member 31. During the deep pressure cleaning stage, combined with Figures 6 to 9After the spring body 23 hugs the first column 25, the pressing part of the second column 421 contacts the top surface of the first column 25. When the second column 421 continues to move downward, the first column 25 moves down along the groove 22, the first elastic element 24 is compressed, and a relative sliding is formed between the first column 25 and the spring body 23. The spring body 23 scrapes the conductive contact surface of the outer wall of the first column 25 to reduce the influence of surface deposits on contact conductivity. When the second ring body 32 contacts the top surface of the first ring body 21 or the limiting surface in the base 1, the second ring body 32 stops moving downward. The remaining pressure applied from the outside is absorbed by the first elastic element 24 to reduce the impact on the first column 25 and the spring body 23. During the reset disconnection phase, combined with Figures 6 to 9 After the external pressure is released, the first elastic element 24 releases its elastic force and pushes the first column 25 upward along the groove 22. The second elastic element 31 releases its elastic force and pushes the second ring 32 upward. When the second ring 32 moves upward, the first inclined surface 321 gradually releases its pressure on the spring body 23. The spring body 23 returns to its original position away from the first column 25 due to its own elasticity. The contact section of the spring body 23 leaves the first column 25, and the two contacts are disconnected. When the second ring 32 moves upward, the second inclined surface 322 releases its radial compression on the third elastic element 33. The third elastic element 33 contracts inward due to its own elasticity. The outer wall of the third elastic element 33 leaves the annular baffle of the base 1. The guide assembly 4, the sealing assembly 3, and the conductive assembly 2 return to their initial positions.

[0038] In summary, this switch structure forms a force-guiding structure through the keycap 43, ball 42, second column 421, third ring 41, and ball bearing 411, converting the inclined pressing force into a pressing force transmitted along the height direction. The first inclined surface 321 of the second ring 32 pushes the spring body 23 to hug the first column 25 to establish stable conduction. The second inclined surface 322 of the second ring 32 pushes the third elastic element 33 to expand to seal the gap where dust enters. The pressing part of the second column 421 pushes the first column 25 to compress the first elastic element 24 to form a buffer and scrape and clean the conductive contact surface. After the external pressing force is released, the first elastic element 24 pushes the first column 25 to reset, the second elastic element 31 pushes the second ring 32 to reset, and the third elastic element 33 and the spring body 23 reset by their own elasticity, so that the switch structure is disconnected.

The multi-plate gold-plated fitting irregular-shaped tactile switch structure according to claim 1, characterized in that: The second ring (32) has a second inclined surface (322) on its outer side, and a third elastic element (33) is sleeved on the outer side of the second ring (32). The third elastic element (33) has a third inclined surface (331) on its outer side. The third inclined surface (331) is close to the second inclined surface (322). When the second ring (32) moves along the first direction, the second inclined surface (322) pushes the third elastic element (33) to expand toward the edge of the base (1).

7. The multi-plate gold-plated fitting irregular-shaped tactile switch structure according to claim 1, characterized in that: The sphere (42) has a second column (421) at its bottom. The second column (421) passes through the third ring (41). The third ring (41) has a ball (411) on it. The ball (411) abuts against the outer wall of the second column (421). When the second column (421) moves in the first direction, it maintains its direction of movement through the ball (411).

8. The multi-plate gold-plated fitting irregular-shaped tactile switch structure according to claim 1, characterized in that: The ball (42) is provided with a keycap (43), and the keycap (43) is provided with a hemispherical groove that slides with the ball (42). When the keycap (43) is subjected to tilting pressure, it deflects relative to the ball (42), and the ball (42) pushes the second ring (32) along the first direction.

9. The multi-plate gold-plated fitting irregular-shaped tactile switch structure according to claim 1, characterized in that: The sphere (42) has a second column (421) at its bottom. The second column (421) has an annular pressing surface that presses against the second ring (32). The second column (421) has a pressing part facing the first column (25). The annular pressing surface first pushes the second ring (32) to move, so that the spring body (23) hugs the first column (25). The pressing part then pushes the first column (25) to move in a third direction.

10. A triggering method for a multi-plate gold-plated fitted irregular-shaped tactile switch structure, applied to the multi-plate gold-plated fitted irregular-shaped tactile switch structure according to any one of claims 1 to 9, characterized in that, The steps include the following: S1: Press the sphere (42) so that the sphere (42) moves closer to the base (1) in the first direction; S2: The sphere (42) pushes the second ring (32) to move, and the second ring (32) pushes the spring body (23) to approach the first column (25) along the second direction; S3: The spring sheet (23) hugs the first column (25), so that the spring sheet (23) and the first column (25) form a conductive contact; S4: Continue pressing the sphere (42), the first column (25) moves closer to the base (1) along a third direction, and the first column (25) slides relative to the spring body (23); S5: Release the pressure on the ball (42), the second ring (32) resets, the spring (23) disengages from the first column (25), and the first column (25) resets.
