Abstract
Description
Technical Field
[0001] This application relates to the field of electrical technology, and in particular to push-button switches. Background Technology
[0002] Omnidirectional push-button switches are widely used due to their advantages such as a wide button operating area and a simple, flat appearance.
[0003] The button of a full-area push-button switch is usually mounted on a panel. The panel has multiple reset structures with positioning through holes. The button has multiple positioning shafts, which are interference-fitted with the corresponding positioning through holes to achieve the connection between the button and the reset structure, so that the button can be automatically reset through the reset structure.
[0004] However, the interference fit between multiple positioning shafts and multiple positioning through holes makes the forming precision requirements of the hole-shaft structure extremely high. This not only significantly increases the difficulty of manufacturing, but also results in defects such as low production yield, high manufacturing cost, and low assembly efficiency.

These three sets of hole-shaft structures cooperate to completely restrict all horizontal displacements of the button within the target plane, ensuring high positioning accuracy. Furthermore, this eliminates the problem of extremely high forming tolerances caused by the fully constrained design of multiple hole-shaft structures, significantly reducing the forming accuracy requirements for the hole-shaft structures, improving production yield, reducing manufacturing costs, simplifying assembly, and increasing assembly efficiency.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0037] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. For example, the term "outer" refers to the edge position area of the push-button switch, and the term "inner" refers to the middle area of the push-button switch or the area near the middle area.
[0038] Current push-button switches typically have buttons mounted on a panel with multiple reset structures. These reset structures have positioning through holes, and the buttons have multiple positioning shafts, each with a corresponding interference fit to one of the positioning through holes. However, this multi-hole-shaft structure requires simultaneous restriction of displacement in two directions within the same plane. The positional accuracy, coaxiality, and dimensional tolerances of each hole and shaft are extremely stringent. Any deviation in the size and / or position of any hole or shaft can lead to assembly failure. This results in extremely high precision requirements for the hole-shaft structure, significantly increasing manufacturing difficulty and leading to low yield rates, high manufacturing costs, and low assembly efficiency.
[0039] To address the aforementioned technical problems, this application provides a push switch, as shown in the attached figure. Figure 1 and attached Figure 2 As shown, the push switch includes: button 1, panel 2, housing 3 and control module 4. Button 1 is pressably connected to panel 2, panel 2 is also connected to housing 3, and control module 4 is housed inside housing 3 and can be triggered by button 1.
[0040] When in use, press button 1. Button 1 triggers control module 4 to perform the operation, and control module 4 can control the operation of the button switch.
[0041] As attached Figure 3 As shown, panel 2 has at least three reset structures 21. Each reset structure 21 is connected to button 1 through a hole-shaft structure 5. The number of hole-shaft structures 5 corresponds one-to-one with the number of reset structures 21. Therefore, the number of hole-shaft structures 5 is at least three.
[0042] As attached Figure 4As shown, the hole-shaft structure 5 includes a first hole-shaft structure 51, a second hole-shaft structure 52, and a third hole-shaft structure 53.
[0043] The first hole-shaft structure 51 is used to simultaneously restrict the movement of button 1 in the target plane along the first direction and the second direction; the second hole-shaft structure 52 is used to restrict the movement of button 1 only in the target plane along the first direction; and the third hole-shaft structure 53 is used to restrict the movement of button 1 only in the target plane along the second direction. The target plane is perpendicular to the pressing direction of button 1; that is, the target plane is a plane parallel to button 1 or panel 2.
[0044] The push switch provided in this application embodiment connects the button 1 and multiple reset structures 21 via multiple hole-shaft structures 5. These hole-shaft structures 5 employ a differentiated constraint design to provide differentiated positioning for the button 1. Specifically, the first hole-shaft structure 51 serves as the primary positioning reference, simultaneously restricting the displacement of the button 1 along the first and second directions within the target plane; the second hole-shaft structure 52 and the third hole-shaft structure 53 respectively restrict displacement in the first and second directions. These three sets of hole-shaft structures 5 cooperate to completely restrict all horizontal displacements of the button 1 within the target plane, ensuring high positioning accuracy. Furthermore, this eliminates the problem of extremely high molding tolerances caused by the full constraint design of multiple sets of hole-shaft structures 5, significantly reducing the molding accuracy requirements for the hole-shaft structures 5, improving production yield, reducing manufacturing costs, lowering assembly difficulty, and improving assembly efficiency.
[0045] It should be noted that the first direction and the second direction are two different directions within the target plane, and there is an angle between the first direction and the second direction, for example, the angle is 90°. To give a further example, for a push switch containing a rectangular or square button, the first direction and the second direction can be the two directions where the two intersecting sides of the rectangle or square are located.
[0046] As mentioned above, the number of hole-shaft structures 5 is at least three. In some examples, the at least three hole-shaft structures 5 form a polygonal profile. That is, the at least three hole-shaft structures 5 serve as vertices of the polygonal profile and can be combined to form a triangular profile, a quadrilateral profile, and other polygonal profiles.
[0047] For the aforementioned polygonal contour, the first hole shaft structure 51, the second hole shaft structure 52, and the third hole shaft structure 53 can serve as any three vertices of the polygonal contour, thereby achieving the effect of limiting the button 1 in two directions of the target plane.
[0048] Furthermore, the projection of the first hole shaft structure 51 onto the line connecting the second hole shaft structure 52 and the third hole shaft structure 53 is located between the second hole shaft structure 52 and the third hole shaft structure 53.
[0049] With this configuration, the projection of the first hole shaft structure 51 (bidirectional limit) falls inside the line segment connecting the second hole shaft structure 52 and the third hole shaft structure 53. The first hole shaft structure 51 is surrounded by the other two unidirectional limit points within the constraint range, which helps to greatly improve the stability of the limit constraint and avoids risks such as button swaying and jamming.
[0050] For example, the first hole shaft structure 51 can be combined with the second hole shaft structure 52 and the third hole shaft structure 53 to form a triangular outline. The projection of the first hole shaft structure 51 can be located at any position on the line connecting the second hole shaft structure 52 and the third hole shaft structure 53. This can be: centered between the second hole shaft structure 52 and the third hole shaft structure 53, or closer to the second hole shaft structure 52, or closer to the third hole shaft structure 53.
[0051] For example, multiple hole-shaft structures 5 can form a quadrilateral profile (e.g., a rectangular profile (including rectangles and squares), a trapezoidal profile (e.g., an isosceles trapezoid), a parallelogram profile, etc.). The first hole-shaft structure 51 serves as three vertices of the quadrilateral profile, respectively, with the second hole-shaft structure 52 and the third hole-shaft structure 53. The projection of the first hole-shaft structure 51 can be located at any position on the line connecting the second hole-shaft structure 52 and the third hole-shaft structure 53. This can be: centered between the second hole-shaft structure 52 and the third hole-shaft structure 53, or closer to the second hole-shaft structure 52, or closer to the third hole-shaft structure 53.
[0052] In some examples, as shown in the appendix Figure 4 As shown, the hole-shaft structure 5 also includes a fourth hole-shaft structure 54, in which the hole 501 and the shaft 502 are clearance-fitted.
[0053] In other words, the fourth hole shaft structure 54 does not restrict the button 1 from moving along the first and second directions in the target plane to avoid introducing over-positioning constraints. It only undertakes the connection and combination function between the reset structure 21 and the button 1. In this way, while ensuring the linkage between the two, it can broaden the layout of multiple sets of reset structures 21, improve the flexibility of the reset structure 21 layout design, and adapt to different product layout requirements, such as meeting the layout requirements of a full-area push-button switch.
[0054] For example, for a full-area push-button switch, in order to make button 1 meet the full-area push-button requirement, as shown in the attached... Figure 4As shown, the first hole shaft structure 51, the second hole shaft structure 52, the third hole shaft structure 53, and the fourth hole shaft structure 54 can be fitted together to form a quadrilateral profile. Further, this quadrilateral profile can be a rectangular profile (for example, the first hole shaft structure 51, the second hole shaft structure 52, the third hole shaft structure 53, and the fourth hole shaft structure 54 are located at the four vertices of the rectangular profile). Furthermore, one of the length or width of the rectangular profile is along a first direction, and the other is along a second direction.
[0055] The above arrangement of the hole shaft structure 5 can adapt to the full-area pressing requirements of the rectangular button 1, which helps to make the support force of the button 1 more uniform, suppress problems such as button 1 warping during pressing, and improve the stability of full-area pressing.
[0056] The first hole shaft structure 51, the second hole shaft structure 52, the third hole shaft structure 53, and the fourth hole shaft structure 54 can be arbitrarily set at any vertex of the four corners of the rectangular outline, and can be selected according to actual needs.
[0057] As an example, see attached Figure 4 As shown, the first hole shaft structure 51 and the fourth hole shaft structure 54 are located on one of the diagonals of the rectangular outline; the second hole shaft structure 52 and the third hole shaft structure 53 are located on the other diagonal of the rectangular outline, so that the projection of the first hole shaft structure 51 on the line connecting the second hole shaft structure 52 and the third hole shaft structure 53 is located between the second hole shaft structure 52 and the third hole shaft structure 53.
[0058] The diagonal arrangement of each hole shaft structure 5 places the first hole shaft structure 51 with bidirectional constraint and the fourth hole shaft structure 54 with clearance connection on opposite diagonals of a rectangle. One of the two diagonal points is the main positioning, and the other is a floating free fit. Even if some hole shaft structures 5 have machining dimension deviations, the fourth hole shaft structure 54 can float freely to compensate for machining errors, effectively avoiding the problem of over-positioning jamming and reducing assembly difficulty.
[0059] The two sets of unidirectional constraint hole shaft structures 5 are placed on the other diagonal of the rectangle. The two unidirectional constraint points are diagonally distributed to form a diagonal orthogonal limit. This can simultaneously pull the two orthogonal directions at both ends of the rectangular button 1, effectively preventing the button 1 from horizontally twisting or deflecting, and ensuring that the button 1 does not deviate when pressed throughout the entire area.
[0060] The following will illustrate specific implementation schemes for each hole shaft structure 5 with reference to the accompanying drawings: As attached Figure 4 As shown, the hole 501 and shaft 502 of the first hole-shaft structure 51 are interference-fitted, and both have the same shape, such as a circle, rectangle, or other polygon, to achieve bidirectional full constraint. For example, Figure 4 As an example, both the hole 501 and the shaft 502 of the first hole-shaft structure 51 are circular.
[0061] As attached Figure 4 As shown, the fourth hole-shaft structure 54 is arranged diagonally opposite to the first hole-shaft structure 51. The hole 501 and shaft 502 of the fourth hole-shaft structure 54 are clearance-fitted, meaning that the size of the hole 501 is larger than the size of the shaft 502, allowing the shaft 502 to move within the hole 501 along the first and second directions without planar positioning constraints. Based on meeting the above requirements, the shapes of the hole 501 and shaft 502 can be arbitrarily set, for example... Figure 4 As an example, both the hole 501 and the shaft 502 of the fourth hole shaft structure 54 are circular, and the diameter of the shaft 502 is smaller than the diameter of the hole 501.
[0062] As attached Figure 4 As shown, the second hole-shaft structure 52 is used to restrict the movement of button 1 in the target plane along a first direction, and the third hole-shaft structure 53 is used to restrict the movement of button 1 in the target plane along a second direction. For example, the second hole-shaft structure 52 restricts the movement of button 1 along... Figure 4 The button moves vertically, and the third hole shaft structure 53 restricts the button 1 along the direction. Figure 4 Move left and right in the middle.
[0063] In some examples, as shown in the appendix Figure 4 As shown, the shaft 502 in the second hole-shaft structure 52 can be a round shaft or a prismatic shaft. The holes 501 in the second hole-shaft structure 52 can all be oblong holes 501, with their shorter side along the first direction having a length less than or equal to the maximum diameter of the shaft 502, and their longer side along the second direction having a length greater than the maximum diameter of the shaft 502. Thus, the shaft 502 is constrained within the hole 501 and cannot move along the first direction, but can only move along the second direction.
[0064] In some examples, as shown in the appendix Figure 4 As shown, the shaft 502 in the third hole shaft structure 53 can be a round shaft or a prismatic shaft. The holes 501 in the third hole shaft structure 53 can all be oblong holes 501, with their short sides along the second direction and a length less than or equal to the maximum diameter of the shaft 502, and their long sides along the first direction and a length greater than the maximum diameter of the shaft 502. Thus, the shaft 502 is constrained within the hole 501 and cannot move along the second direction, but can only move along the first direction.
[0065] For the aforementioned push-button switch, its reset structure 21 can be a spring (e.g., an integrated spring), or it can be other elastic structures, such as a spring structure, an elastic column structure, etc., as long as it can perform the function of pressing and resetting the button 1.
[0066] In this embodiment of the application, the reset structure 21 is exemplified as a long strip-shaped spring, as shown in the attached figure. Figure 5As shown, one end of the reset structure 21 along its length is fixed, and the other end is suspended. The end of the reset structure 21 that is fixed to the panel 2 is called the fixed end 212, and the end of the reset structure 21 that is suspended is called the suspended end 211. Therefore, the reset structure 21 can be called a cantilever reset structure 21.
[0067] In this embodiment, the reset structure 21 adopts a cantilever structure with one end fixed and the other end suspended. It relies on the suspended end 211 to bend under force to achieve the pressing and rebound, which has the advantages of sufficient deformation and clear and sensitive elastic feedback.
[0068] When the reset structure 21 is in the form of a spring clip, as shown in the attached... Figure 7 As shown, the surface of the reset structure 21 facing the button 1 is a plane, and the surface of the reset structure 21 away from the button 1 is an inclined plane, so that the thickness of the reset structure 21 gradually increases from the suspended end 211 of the button 1 to the fixed end 212.
[0069] This design, with its thickened fixed end, enhances the spring's bending strength, while its thinned, suspended end reduces rigidity, thus improving the spring's elasticity in the suspended end region.
[0070] In conjunction with the above-described structure of the reset structure 21, the hole-shaft structure 5 includes: a hole 501 and a shaft 502, as shown in the attached figure. Figure 7 As shown, hole 501 is disposed in either the suspended end 211 of reset structure 21 or button 1, and shaft 502 is disposed in either the suspended end 211 of reset structure 21 or button 1.
[0071] This could be achieved by having hole 501 located at the suspended end 211 of reset structure 21, and shaft 502 located on the surface of button 1 facing hole 501. Alternatively, shaft 502 could be located at the suspended end 211 of reset structure 21, and hole 501 located on the surface of button 1 facing shaft 502.
[0072] The hole-shaft structure 5 is located at the suspended end 211 of the reset structure 21, which can directly transmit the pressing force of the button 1, resulting in a sensitive trigger response. In addition, with the cooperation of the hole 501 and the shaft 502, the button 1 moves synchronously with the suspended end 211 of the reset structure 21 to achieve automatic reset.
[0073] In some examples, as shown in the appendix Figure 7 As shown, either the suspended end 211 of the reset structure 21 or the button 1 is provided with a boss 503, with a hole 501 recessed inside the boss 503, or a shaft 502 protruding from the surface of the boss 503.
[0074] For example, the boss 503 can be disposed on the surface of the button 1 facing the reset structure 21, and the hole 501 is recessed inside the boss 503. Alternatively, the boss 503 can be disposed on the surface of the button 1 facing the reset structure 21, and the shaft 502 protrudes from the surface of the boss 503. Alternatively, the boss 503 can be disposed on the suspended end 211 of the reset structure 21, and the hole 501 is recessed inside the boss 503. Alternatively, the boss 503 can be disposed on the suspended end 211 of the reset structure 21, and the shaft 502 protrudes from the surface of the boss 503.
[0075] By arranging the aforementioned boss 503, on the one hand, it facilitates extending the axial mating length of the hole-shaft structure 5 in the direction of 502, enhancing the guiding and positioning effect; on the other hand, the boss 503 can serve as a force application point for the hole-shaft structure 5, preventing direct contact between the button 1 body and the reset structure 21 body, eliminating structural interference within the pressing stroke, and ensuring smooth and reliable pressing transmission. Furthermore, the boss 503 can also locally reinforce the reset structure 21 or the button 1, improving the structural strength and fatigue resistance of the hole 501-shaft 502 mating area, and extending its service life.
[0076] Regarding the aforementioned cantilever reset structure 21, which is a commonly used spring-loaded structure in push-button switches, the cantilever reset structure 21 in existing push-button switches is prone to fatigue damage. The inventors have investigated the causes of this damage. See [link to relevant documentation]. Figure 18 The study found that the initial pressure point of the reset structure 21 is position A, the distal end of its through hole 501. After the reset structure 21 bends downward, the pressure point gradually shifts to position B, the proximal end of its through hole 501, shortening the effective force-bearing length and causing a sudden increase in pressure. Simultaneously, at the same downward stroke, position B generates higher stress in the reset structure 21 compared to position A, leading to stress yielding, fatigue fracture, and other problems, making the reset structure 21 prone to fatigue damage. Furthermore, the inventors conducted simulation analysis of the stress at positions A and B of the reset structure 21, and the obtained stress simulation cloud diagram also clearly shows that the stress concentration at position B is significantly stronger. Based on this, the inventors concluded that the stress at position B is the main reason for the fatigue damage of the reset structure 21.
[0077] To address the aforementioned issues, the embodiments of this application, as shown in the appendix... Figure 7 and in conjunction with the appendix Figure 9As shown, the suspended end 211 of the reset structure 21 has a first side 2111 close to the fixed end 212 of the reset structure 21 and a second side 2112 away from the fixed end 212 of the reset structure 21; along the pressing direction of the button 1, the hole shaft structure 5 can drive the second side 2112 of the suspended end 211 of the reset structure 21, and avoids the first side 2111 of the suspended end 211 of the reset structure 21.
[0078] It should be noted that the first side 2111 of the suspended end 211 of the reset structure 21 is close to its fixed end 212, so it can be referred to as the proximal side or proximal end; the second side 2112 of the suspended end 211 of the reset structure 21 is far away from its fixed end 212, so it can be referred to as the distal side or distal end.
[0079] When button 1 is pressed, the shaft structure 5 applies downward pressure only to the second side 2112 (far side) of the suspended end 211 of the reset structure 21 to complete the drive. The first side 2111 (proximal side) of the suspended end 211 of the reset structure 21 can be designed with a stepped structure to avoid gaps. In this way, during the pressing process, the pressing force point remains stable at the far side position, and the effective lever arm of the reset structure 21 is relatively long, which can effectively avoid the problem of sudden increase in pressing force caused by forward force shift. At the same time, under the same downward stroke, the force on the far side of the suspended end 211 of the reset structure 21 is relatively smaller than that on the proximal side, which helps to reduce the internal stress generated on the reset structure 21. These factors significantly reduce the probability of fatigue damage to the reset structure 21, thus improving its service life.
[0080] As an example, see attached Figure 7 and in conjunction with the appendix Figure 9 As shown, a boss 503 is disposed on the button 1, a hole 501 is recessed inside the boss 503, and a shaft 502 is disposed on the suspended end 211 of the reset structure 21. The distance between the first side 2111 of the boss 503 facing the suspended end 211 of the reset structure 21 and the reset structure 21 is smaller than the distance between the second side 2112 of the boss 503 facing the suspended end 211 of the reset structure 21 and the reset structure 21, thereby allowing the hole-shaft structure 5 to avoid the vicinity of the suspended end 211 of the reset structure 21.
[0081] One embodiment of the above solution is that the first side 2111 of the boss 503 facing the suspended end 211 of the reset structure 21 is recessed towards the button 1 relative to the second side 2112 of the boss 503 facing the suspended end 211 of the reset structure 21.
[0082] With this configuration, a clearance structure can be formed on the boss 503 for the proximal side of the suspended end 211 of the reset structure 21. That is, the boss 503 is a concave boss, which allows the hole shaft structure 5 to clear the proximal side of the suspended end 211 of the reset structure 21.
[0083] The inventors also discovered that the holes in traditional hole-shaft structures are mostly through holes. The burrs produced during through hole machining can cause scratches and secondary impacts during the reciprocating motion of the shaft, making it prone to secondary abnormal noises.
[0084] Regarding this type of technical problem, see attached... Figure 7 As shown, in this embodiment of the application, the hole 501 in the shaft 502 hole 501 structure is set as a blind hole.
[0085] Blind holes are structures that are open at one end and closed at the other, which can avoid the problem of exposed burrs in the traditional through-hole 501 machining process from the source and avoid secondary abnormal noise problems.
[0086] In combination with the above-mentioned boss 503 scheme, in some examples, a boss 503 can be set on the button 1, and the hole 501 can be opened in the form of a blind hole inside the boss 503. The side of the boss 503 near the resetting structure 21 is recessed to form a near-end clearance space. In this way, the technical effects of remote driving, near-end clearance, fatigue resistance, and noise reduction can be achieved.
[0087] Of course, the arrangement of the hole 501 and the shaft 502 can also be changed to adapt to different scenarios and needs. For example, the boss 503 can be set at the suspended end 211 of the reset structure 21, and the hole 501 can be opened in the boss 503 in the form of a blind hole. The side of the boss 503 near the end of the reset structure 21 is recessed to form a near-end clearance space.
[0088] Based on any of the aforementioned push-button switches, the button 1 of the push-button switch can adopt a layered stacking structure, as shown in the attached figure. Figure 8 and attached Figure 9 As shown, button 1 includes a top layer 11 and a bottom layer 12 arranged sequentially along the pressing direction. The bottom layer 12 is snapped into the panel 2, and the buckle on the bottom layer 12 faces the outside of button 1.
[0089] The top layer 11 is the appearance material layer, and the bottom layer 12 is the structural support base layer. Button 1 is snapped together with panel 2 through the bottom layer 12. In this layered design of button 1, the bottom layer 12 undertakes the functions of structural connection and force transmission to realize the connection between button 1 and panel 2. This allows the top layer 11 to be flexibly replaced, and various appearance materials such as plastic, metal, and glass can be selected for the top layer 11 according to the needs.
[0090] By positioning the latches on the bottom layer 12 towards the outside of the button 1, rather than towards the inside of the button 1, i.e., not extending towards the inner pressing area, it helps to avoid stacking interference inside the push switch, thereby reducing the thickness of the push switch.
[0091] In some examples, as shown in the appendix Figure 5 and in conjunction with the appendix Figure 10 As shown, panel 2 includes: a plate 201 and a frame 202 surrounding the plate 201; a first buckle 22 is provided at the end of the frame 202 facing the button 1 (of course, the first buckle 22 can also be replaced by a buckle hole, both of which can achieve buckle connection), and a second buckle 13 is provided at the edge of the bottom layer 12 near the frame 202; the second buckle 13 is adapted to engage with the first buckle 22, and the first buckle 22 is located outside the second buckle 13.
[0092] The second latch 13 and the first latch 22 are mutually adapted and engaged, so that the button 1 is limited relative to the panel 2 in the pressing direction. The first latch 22 is located outside the second latch 13, that is, the latch of the second latch 13 faces outward rather than inward, that is, it does not extend towards the inward pressing area. This helps to avoid stacking interference inside the push switch, thereby reducing the thickness of the push switch.
[0093] This is because if the latch of the second latch 13 faces inward, then the first latch 22 will inevitably be located inside the second latch 13. The first latch 22 will inevitably occupy the vertical stacking space of the switch. In addition, there is also space to be reserved between the bottom layer 12 of the button 1 and the panel 2 for pressing. All of the above will significantly increase the thickness of the switch.
[0094] The push switch provided in this application embodiment has its second latch 13 facing outwards, and correspondingly, the first latch 22 is located outside the button 1. This avoids occupying the pressing activity space between the bottom layer 12 and the panel 2, and does not occupy the vertical stacking space, so that the push switch can achieve a lower thickness while retaining sufficient pressing stroke.
[0095] In addition, since the first buckle 22 is located outside the second buckle 13, it does not affect the internal stacking height of the switch, and it also facilitates the expansion of the surface layer 11 with multiple materials. This is because when expanding the surface layer 11 with different materials, only the surface layer 11 needs to be replaced, and there is no need to adjust the vertical dimension between the bottom layer 12 and the panel 2. This ensures that the total thickness of the push switch is within the set standard, and achieves uniform appearance and size for multiple material styles.
[0096] When the push switch has multiple buttons 1, it is necessary to not only set a first buckle 22 on the end of the frame 202 facing the button 1, but also set a first buckle 22 on the panel 2. The first buckle 22 set on the frame 202 and the first buckle 22 set on the panel 2 can be arranged symmetrically.
[0097] For this situation, see attached Figure 5 As shown, panel 2 includes: a panel 201, a frame 202 surrounding the panel 201, and a protruding rib 203 protruding from the center of the panel 201; both the frame 202 and the protruding rib 203 are provided with snap-fit structures, which are used to snap-fit with buckles provided on the bottom layer 12. For example, as shown in the attached... Figure 10 As shown, the snap-fit structure provided on the frame 202 and the protruding rib 203 is the first snap-fit 22, and the snap-fit provided on the bottom layer 12 is the second snap-fit 13.
[0098] The protruding rib 203 is arranged on the plate 201, so that the height of the protruding rib 203 matches the height of the frame 202 and forms a height difference with the plate 201. This not only provides a carrier for the setting of the snap-fit structure, but also facilitates the formation of sufficient pressing space between the button 1 and the panel 2.
[0099] In some examples, snap-fit structures can be provided on both sides of the opposite arrangement of the rib 203. In this way, two buttons 1 can be symmetrically arranged on opposite sides of the rib 203. Thus, one rib 203 can provide snap-fit structures for two buttons 1 at the same time, which helps to improve the integration of the panel 2 and simplify its structural layout.
[0100] To accommodate the arrangement of the above-mentioned snap-fit structure, see attached... Figure 10 As shown, the end of the frame 202 facing the button 1 can be arranged to protrude towards the button 1 relative to the end of the plate 201 facing the button 1.
[0101] With the above configuration, the frame 202 of panel 2 protrudes and the plate 201 is recessed, forming a height difference between the two. The protruding frame 202 provides a carrier for the outer buckle, which facilitates the setting of the first buckle 22. Moreover, the height difference also helps to form sufficient pressing space between the bottom layer 12 of button 1 and panel 2.
[0102] Furthermore, as shown in the appendix Figure 10 As shown, the plate 201 has a first opening 23 facing the latch on the bottom layer 12, for example, the second latch 13. By providing the first opening 23 on the plate 201 of the panel 2 directly opposite the second latch 13, a downward pressure clearance space can be provided for the latch. This ensures that the first latch 22 and the second latch 13 can be smoothly engaged, and also helps to keep the push switch relatively thin.
[0103] Regarding the aforementioned push switch, the push switch includes a button 1, a panel 2, a housing 3, and a control module 4. The control module 4 is the functional execution component of the switch, which is assembled in the internal cavity of the housing 3. It can be reliably triggered by the pressing action of the button 1 to realize core functions such as switch on / off and status indication.
[0104] In some examples, the control module 4 includes a control circuit board 43, as well as microswitches 41, indicator lights 42 and other auxiliary electronic devices electrically connected to the control circuit board 43. The arrangement of the control module 4 is described exemplarily below.
[0105] In some examples, as shown in the appendix Figure 11 As shown, the control module 4 includes a micro switch 41 that passes through the panel 2, such that the contact of the micro switch 41 is located on the side of the panel 2 near the button 1; the button 1 has a driving part 15, which is used to drive the contact 411 of the micro switch 41.
[0106] The micro switch 41 is the core trigger sensing component. It can be a small, tactile micro switch 41, which is fixed to the control circuit board 43 by surface mount or pin mounting. The micro switch 41 has a contact 411 for elastic triggering and a reset structure. When the contact 411 is triggered by the driving part 15 of the button 1, the micro switch 41 is turned on or off. When the press is released, the button 1 automatically springs back, and the contact 411 of the micro switch 41 is automatically reset under the action of the reset structure, completing one press trigger action.
[0107] In this embodiment, the micro switch 41 penetrates the panel 2, so that the contact 411 of the micro switch 41 is located on the side of the panel 2 near the button 1, that is, the micro switch 41 protrudes from the surface of the panel 2. This can effectively shorten the height of the driving part 15 of the button 1. When the height of the driving part 15 is low, the driving position offset during pressing can be greatly reduced, avoiding problems such as easy swaying when the driving part 15 is long, and improving the triggering stability of pressing the entire area.
[0108] In some examples, as shown in the appendix Figure 9 As shown, the driving part 15 protrudes from the surface of the button 1 facing the panel 2. The driving part 15 can be cylindrical, prismatic, or cross-shaped, for example, Figure 9 The example shows that the drive unit 15 is cross-shaped.
[0109] As mentioned above, as attached Figure 12 As shown, the control module 4 also includes an indicator light 42. To ensure that the light emitted by the indicator light 42 is emitted smoothly, the panel 2 is provided with a second opening 24 facing the indicator light 42, and the button 1 is provided with a first light-emitting hole 14 facing the second opening 24 (see...). Figure 8Thus, the light from indicator light 42 passes through the second opening 24 and the first light outlet 14 and shines outward from button 1.
[0110] It should be noted that the second opening 24 can not only serve as a light outlet, but also allow the micro switch 41 and the light guide 6 described below to pass through.
[0111] Traditional push-button switches typically have their trigger mechanism located at the center of button 1. If an indicator light 42 is required, a ring-shaped light-emitting structure is usually placed around button 1. This approach has several inherent drawbacks: First, button 1 must be made entirely of light-guiding material, and its surface must be light-shielded and laser-engraved to create a light-transmitting area, resulting in high material and processing costs. Second, the ring-shaped light-emitting structure has high brightness and a large light-emitting range, making it easy for light to leak out from the assembly seams of button 1, affecting its appearance and texture. If a light-blocking wall is added to solve the light leakage problem, it will increase the product's axial thickness 502, contradicting the ultra-thin design concept.
[0112] To address the aforementioned issues, this embodiment centrally positions the first light-emitting hole 14 on the button 1. This means the central area of the button 1 provides a light path for the indicator light 42, ensuring the indicator light 42 emits light centrally, making the marking position prominent and focused, providing a clear and intuitive indication, and improving the user experience. Furthermore, this arrangement avoids the need for the entire button to use light-guiding materials, eliminating the need for complex post-processing steps such as light-shielding treatment and laser engraving. Directional light transmission can be achieved simply by aligning the opening 501 on the button 1, significantly simplifying the manufacturing process and reducing costs. In addition, the central single-point light emission avoids large-area ring-shaped light emission, fundamentally reducing light leakage from the side seams of the button 1. This eliminates the need for an additional ring-shaped light-blocking structure and does not increase the axial thickness of the switch 502, aligning with the switch's ultra-thin design goal.
[0113] It should be noted that when the first light-emitting hole 14 is centered on the button 1, it means that the micro switch 41 is eccentrically arranged relative to the button 1. This means that the micro switch 41 is closer to the snap-fit position (i.e., fixed point) between the button 1 and the panel 2, which also helps to shorten the pressing stroke of the button 1.
[0114] Regarding the above-mentioned solution with indicator light 42, see attached... Figure 12 As shown, the push switch also includes a light guide 6, which is connected to the button 1. The light guide 6 has a light-emitting end 61 and a light-incoming end 62.
[0115] The light-emitting end 61 of the light guide 6 is housed within the first light-emitting hole 14. That is, the light-emitting end 61 of the light guide 6 and the first light-emitting hole 14 can be interference-fitted. The light-inlet end 62 of the light guide 6 can be arranged directly opposite the indicator light 42.
[0116] By setting a light guide 6 on button 1, the light emitted by indicator light 42 can be directionally transmitted and optically homogenized, optimizing the luminous effect of the central indicator light without increasing the product thickness.
[0117] Furthermore, as shown in the appendix Figure 12 As shown, the light-inlet end 62 of the light guide 6 has a recessed arrangement on the surface facing the indicator light 42, that is, the light guide 6 has a concave light-guiding surface 620 facing the indicator light 42.
[0118] The concave arc surface of the concave light guide surface 620 can further converge and homogenize the divergent light from the indicator light 42, breaking up the difference in light spots with bright centers and dark edges formed by direct illumination from point light sources, making the brightness of the entire light-emitting area uniform and avoiding defects such as local bright spots.
[0119] Furthermore, the concave light guide surface 620 is directly integrally formed on the light inlet end 62 of the light guide component 6, which does not increase the product thickness compared to adding additional optical components such as light equalizers and diffusion films.
[0120] The shape of the light guide 6 can be adapted to the actual space inside the switch. The volume of the light-inlet end 62 of the light guide 6 should be designed to be as large as possible to provide a concave light guide surface 620 with a sufficiently large area. The light-outlet end 61 of the light guide 6 should be adapted to the structure and size of the first light-outlet hole 14, so that its volume can be designed to be as small as possible to enhance the aesthetics of the push switch.
[0121] In some examples, as shown in the appendix Figure 13 As shown, the light guide 6 also includes a light guide body 60 located between the light emitting end 61 and the light receiving end 62. The light guide body 60 is used to make the projections of the light emitting end 61 and the light receiving end 62 on the button 1 at least partially staggered. For example, this can be a partially staggered arrangement or a completely staggered arrangement.
[0122] The light guide body 60 is used to provide a light output path from the light inlet end 62 to the light outlet end 61. The light guide body 60 is used to connect the light outlet end 61 and the light inlet end 62 in a staggered manner to adapt to scenarios where the optical paths of the indicator light 42 and the first light outlet hole 14 cannot be aligned, there is a misalignment or offset, or the internal assembly space is limited and cannot be directly connected to the light guide, so as to avoid internal space interference.
[0123] The structure of the light guide body 60 can be designed according to the actual space conditions. The light guide body 60 can be a straight structure or an inclined structure. An avoidance structure can also be set on the light guide body 60.
[0124] In some examples, connecting ears are provided on opposite sides of the light guide body 60, and connecting holes are provided on the connecting ears. Connecting posts are provided on the surface of the button 1 facing the panel 2. The light guide 6 can be fixed on the button 1 by connecting the connecting posts and connecting ears.
[0125] In some examples, the light guide 6 can be integrally formed from a light guide material, such as optical grade PC, optical grade PMMA, etc.
[0126] Based on the aforementioned push-button switch solution containing indicator light 42, as shown in the attached... Figure 12 As shown, the control circuit board 43 can have a second light-emitting hole 431, and the indicator light 42 is located on the side of the control circuit board 43 away from the panel 2, and the indicator light 42 faces the second light-emitting hole 431.
[0127] The traditional method of mounting the indicator light 42 upright on the side of the circuit board facing the panel 2 results in the lamp body occupying a large amount of vertical assembly space, leading to an increase in product thickness. In this embodiment, the indicator light 42 (e.g., LED) is mounted upside down on the back of the control circuit board 43. A second light-emitting hole 431 is opened by utilizing the thickness of the board body 201 of the control circuit board 43 to achieve light transmission. There is no need to reserve installation space for the lamp body between the control circuit board 43 and the panel 2, which can effectively reduce the thickness of the switch.
[0128] The push switch involved in the embodiments of this application, as shown in the attached document... Figure 12 As shown, its housing 3 includes: a rear seat 31 and a bracket 32 connected to the outside of the rear seat 31, the bracket 32 is also connected to the panel 2; the control module 4 includes a control circuit board 43, the control circuit board 43 is embedded inside the rear seat 31.
[0129] The size and position of the control circuit board 43 can be adapted to the internal cavity of the rear seat 31, so that the control circuit board 43 can be completely stored in the internal cavity of the rear seat 31. In this way, the control circuit board 43 is hidden in the cavity of the rear seat 31, and only the three necessary structures of bracket 32, panel 2 and button 1 are retained on the outside of the mounting surface. This can further reduce the protrusion height of the switch after installation, making it more suitable for small and compact installation scenarios.
[0130] Based on any of the aforementioned push-button switches, the button 1 can be set to a single switch, that is, the push-button switch is a single-opening type, and the arrangement of its hole shaft structure 5 can adopt any of the aforementioned implementation schemes.
[0131] Based on any of the aforementioned push-button switches, as shown in the attached... Figure 14-16 As shown, there can be multiple buttons 1. Correspondingly, the panel 2 includes multiple panel units 200, and the number of panel units 200 is greater than or equal to the number of buttons 1.
[0132] Regarding the aforementioned situation where the number of panel units 200 is greater than or equal to the number of buttons 1, this includes the following solutions: (1) The number of panel units 200 is equal to the number of buttons 1. At this time, multiple buttons 1 correspond one-to-one with multiple panels 2.
[0133] (2) The number of panel units 200 is greater than the number of buttons 1. In this case, for a panel 2 containing a large number of panel units 200, it can accommodate a variety of numbers of buttons 1. For example, when panel 2 includes four panel units 200, it can accommodate one, two, three or four buttons 1.
[0134] As attached Figure 3 As shown, the example illustrates that there are four panel units 200 arranged in a 2×2 array. Each panel unit 200 is provided with a first hole shaft structure 51, a second hole shaft structure 52, a third hole shaft structure 53 and a fourth hole shaft structure 54. The first hole shaft structure 51, the second hole shaft structure 52, the third hole shaft structure 53 and the fourth hole shaft structure 54 cooperate to form a rectangular outline.
[0135] In this case, the number of buttons 1 can be set to one, two, three or four. When the number of buttons 1 is less than the number of panel units 200, only a portion of the hole and shaft structures 5 corresponding to the four panel units 200 are used, and the remaining hole and shaft structures 5 can be left idle. The hole and shaft structures 5 to be used can be selected adaptively according to the number and orientation of the buttons 1.
[0136] In some examples, when the number of panel units 200 is greater than the number of buttons 1, at least some of the hole-shaft structures 5 on some buttons 1 are set as avoidance structures 504. These avoidance structures 504 are used to avoid the corresponding hole-shaft structures 5 on the panel unit 200. That is, according to actual needs, only some of the hole-shaft structures 5 are used, and the remaining hole-shaft structures 5 are idle. Therefore, these idle hole-shaft structures 5 can be designed as avoidance structures 504 to avoid interference.
[0137] For example, when the hole shaft structure 5 on the button 1 is a hole 501, and the hole 501 is formed in the boss 503, the protrusion height of the boss 503 can be designed to be low, and the size of the hole 501 can be designed to be large, so as to avoid interference with the shaft 502 on the panel unit 200.
[0138] As can be seen, for the above solution, the number of panel units 200 is greater than or equal to the number of buttons, which allows the same panel 2 to be flexibly equipped with different numbers of buttons 1 without the need to open molds and produce panel 2 separately for the number of buttons 1, thus having the advantage of strong versatility.
[0139] Based on the above schemes, the following will be combined with the appendix. Figure 14 - Appendix Figure 17 This section will explain the different types of push switches.
[0140] Appendix Figure 14 A single-pole push-button switch is provided, as shown in the attached figure. Figure 14 As shown, it includes a button 1, and a panel 2 including four panel units 200 arranged in a 2×2 array. The single button 1 simultaneously mates with all four panel units 200. The hole-shaft structure 5 (i.e., hole 501) located in the outer edge region of the button 1 is used to mate with the corresponding hole-shaft structures 5 (i.e., shaft 502) on the four panel units 200. The hole-shaft structure 5 located in the inner region of the button 1 is designed as an avoidance structure 504 to avoid interference.
[0141] Appendix Figure 15 A two-prong push-button switch is provided, as shown in the attached figure. Figure 15 As shown, it includes two buttons 1, and the panel 2 includes four panel units 200 arranged in a 2×2 array, with each button 1 cooperating with two panel units 200 simultaneously. A hole-shaft structure 5 (i.e., hole 501) located in the outer edge region of each button 1 is used to engage with corresponding hole-shaft structures 5 (i.e., shaft 502) on two of the panel units 200. The hole-shaft structure 5 located in the inner region of the button 1 is designed as an avoidance structure 504 to prevent interference.
[0142] Appendix Figure 16 A two-prong push-button switch is provided, as shown in the attached figure. Figure 16 As shown, it includes three buttons 1, and the panel 2 includes four panel units 200 arranged in a 2×2 array. One button 1 simultaneously engages with two panel units 200, and the other two buttons 1 each engage with one panel unit 200.
[0143] Meanwhile, the hole-shaft structure 5 (i.e., hole 501) in the outer edge region of the button 1 that cooperates with the two panel units 200 is used to cooperate with the corresponding hole-shaft structure 5 (i.e. shaft 502) on the two panel units 200, and the hole-shaft structure 5 in the inner region of the button 1 is designed as an avoidance structure 504 to avoid interference.
[0144] Appendix Figure 17 A two-prong push-button switch is provided, as shown in the attached figure. Figure 17As shown, it includes four buttons 1, and the panel 2 includes four panel units 200 arranged in a 2×2 array. Each button 1 is respectively matched with a panel unit 200, and the hole-shaft structure (i.e., hole 501) on the button 1 is respectively used to match the corresponding hole-shaft structure 5 (i.e. shaft 502) on the corresponding panel unit 200.
[0145] Figures 14-17 Although the button 1 of the different types of push switches described herein has different arrangements, their panels 2 can be designed to be the same, that is, the same panel 2 is used. It can be seen that this gives the panel 2 the advantage of strong versatility.
[0146] Regarding the aforementioned solutions for the four panel units 200, as shown in the appendix... Figure 3 As shown, for any two adjacent panel units 200, the first hole shaft structure 51 corresponding to one panel unit 200 is arranged adjacent to the first hole shaft structure 51 corresponding to the other panel unit 200. That is, the four first hole shaft structures 51 corresponding to the four panel units 200 are all located in the inner area of the push switch. This arrangement allows the first hole shaft structure 51, which is most sensitive to bidirectional constraints and tolerances, to be located in the inner area of the push switch, rather than at the edge, which is more advantageous in reducing single-button wobble and sway, and improving the pressing feel.
[0147] For any of the aforementioned push switches, the push switch provided in this application embodiment can be a global intelligent push switch, and the composition of the control module 4 can be designed based on this, which will not be described in detail here.
[0148] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
[0149] The term "and / or" in the embodiments of this application is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.
[0150] The above description is only for the purpose of enabling those skilled in the art to understand the technical solution of this application, and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
