[0024] like Figures 1 to 3 As shown, a switch structure 1000 is provided in the embodiment, which can be applied to a switch assembly 2000 of a two-wheeled vehicle such as a motorcycle or an electric bicycle to realize function switching.

[0025] like Figure 3 and Figure 4 As shown, the switch structure 1000 includes a circuit board 200 , an elastic seat 300 and a conductive contact 400 .

[0026] A metal contact 220 is disposed on one side of the circuit board 200. An elastic seat 300 is disposed on a side of the circuit board 200 close to the metal contact 220. A mounting cavity 301 and a gas storage cavity 302 are disposed on the side of the elastic seat 300 facing the circuit board 200. The metal contact 220 may be located in the mounting cavity 301. A conductive contact 400 may be disposed on a side of the elastic seat 300 facing the circuit board 200, and the conductive contact 400 is also located in the mounting cavity 301. When the elastic seat 300 is not subjected to an external force, the conductive contact 400 may be spaced apart from the metal contact 220.

[0027] In addition, the elastic seat 300 is sealed against the circuit board 200, so that the assembly cavity 301 and the air storage cavity 302 can be isolated from the external environment and are in a sealed state, thereby preventing pollutants such as water vapor and dust from the external environment from entering the assembly cavity 301 and the air storage cavity 302, and also realizing waterproof protection for the metal contacts 220 and the conductive contacts 400, reducing the probability of the metal contacts 220 and the conductive contacts 400 being corroded and damaged, and extending the service life of the switch structure 1000.

[0028] When the user needs to operate the switch structure 1000, a pressing force can be applied to the elastic seat 300 to cause the elastic seat 300 to deform elastically at the position corresponding to the assembly cavity 301. Driven by the elastic seat 300, the conductive contact 400 can gradually contact the metal contact 220. When the conductive contact 400 contacts the metal contact 220, the metal contact 220 can be turned on and generate a corresponding electrical signal. In the process of the user pressing the elastic seat 300, the gas in the assembly cavity 301 can be squeezed into the gas storage cavity 302, so that the air pressure in the assembly cavity 301 can be kept basically balanced, the increase in the air pressure in the assembly cavity 301 can be reduced, and a large resistance to the user's operation can be avoided, so that the user can press and operate the switch structure 1000, which is convenient for the user to operate and improves the comfort of the user's operation.

[0029] like Figures 1 to 3 As shown, in some embodiments, the switch structure 1000 further includes a housing 110, a bracket 120 and a cover plate 130. The housing 110 may be annular, and the interior of the housing 110 is a hollow structure. The side of the housing 110 facing its own central axis may be configured as an opening 1101.

[0030] In some embodiments, the bracket 120 may be roughly in the shape of a semicircle. The bracket 120 may be disposed at the opening 1101 of the housing 110, and may partially seal the opening 1101. The bracket 120 and the housing 110 may be fixed by screw connection or snap connection, etc., to prevent the bracket 120 from being separated from the housing 110 at will. The opening 1101 relative to the exposed portion of the bracket 120 may facilitate wiring.

[0031] In some other embodiments, the bracket 120 may also be in a circular shape and disposed at the opening 1101 of the shell 110 . Accordingly, the bracket 120 may fully seal the opening 1101 of the shell 110 .

[0032] In some embodiments, the housing 110 may be an outer shell in the switch assembly 2000. The bracket 120 may be an inner bracket in the switch assembly 2000.

[0033] Of course, in other embodiments, the housing 110 may also be a part of the outer shell of the switch assembly 2000. The bracket 120 may also be a part of the internal bracket of the switch assembly 2000.

[0034] like Figures 1 to 3 As shown, in some embodiments, the cover plate 130 may be disposed on the side of the bracket 120 facing the housing 110 and located inside the housing 110. In the embodiment, the circuit board 200 and the elastic seat 300 may be disposed between the cover plate 130 and the bracket 120, and the elastic seat 300 is located on the side of the circuit board 200 facing the cover plate 130. When the cover plate 130 and the bracket 120 are assembled, the elastic seat 300 may also be pressed against the circuit board 200 so that the elastic seat 300 and the circuit board 200 are sealed and matched.

[0035] In some embodiments, the switch structure 1000 further includes a key cap 140 and a guide column 600. The key cap 140 may be movably disposed relative to the housing 110 and communicate with the interior of the housing 110. For example, in some embodiments, the key cap 140 may be floatingly mounted on the housing 110.

[0036] In other embodiments, the key cap 140 may also be swung or rotated relative to the housing 110 .

[0037] As 1 to Figure 3 As shown, the guide column 600 may include an integrated limiting flange 610 and a column portion 620. The limiting flange 610 may be located at one end of the column portion 620, and the limiting flange 610 may be provided protrudingly relative to the circumferential side of the column portion 620. In an embodiment, the limiting flange 610 may be provided on a side of the cover plate 130 facing the elastic seat 300. When the switch structure 1000 is not subjected to an external force, one side of the limiting flange 610 may abut against a side of the elastic seat 300 facing away from the circuit board 200, and the other side of the limiting flange 610 facing away from the elastic seat 300 may abut against a side of the cover plate 130 facing the elastic seat 300 or there may be a small gap.

[0038] The column portion 620 may be located on the side of the limiting flange 610 away from the elastic seat 300. The column portion 620 may be slidably penetrated through the cover plate 130 and protrude relative to the side of the cover plate 130 away from the elastic seat 300. Accordingly, a through hole 131 may be provided on the cover plate 130 for the column portion 620 to pass through. The diameter of the through hole 131 is smaller than the outer diameter of the limiting flange 610, so that the limiting flange 610 can be limited to the side of the cover plate 130 facing the elastic seat 300. In addition, the diameter of the through hole 131 may be equal to or slightly larger than the diameter of the column portion 620, which can ensure that the column portion 620 slides smoothly relative to the cover plate 130. At the same time, it can also provide a guiding and limiting function for the column portion 620, reduce the possibility of the column portion 620 being skewed, and thus reduce the probability of the guide column 600 being skewed.

[0039] In the embodiment, the column portion 620 may be a cylindrical or polygonal column, and the shape of the via hole 131 may be adapted to the shape of the column portion 620. When the column portion 620 is a polygonal column, the diameter of the column portion 620 may refer to the diameter of its circumscribed circle.

[0040] In the embodiment, the limiting flange 610 may also be a circular ring structure or a polygonal ring structure. When the limiting flange 610 is a polygonal ring structure, the outer diameter of the limiting flange 610 may refer to the diameter of the circumscribed circle of the limiting flange 610 .

[0041] In some embodiments, one end of the column portion 620 away from the limiting flange 610 may be spaced opposite to or abutted against the keycap 140, and the end of the column portion 620 away from the limiting flange 610 is located on the movable path of the keycap 140. During use, when the user operates the keycap 140, the pressing force can be transmitted to the position of the corresponding assembly cavity 301 in the elastic seat 300 through the guide column 600, and then, the position of the corresponding assembly cavity 301 in the elastic seat 300 can be driven to undergo elastic deformation, so that the conductive contact 400 gradually approaches and contacts the metal contact 220, so that the metal contact 220 is turned on. When the user cancels the force applied to the keycap 140, the elastic seat 300 can be reset under the action of its own elastic force, and push the guide column 600 and the keycap 140 to reset synchronously.

[0042] like Figure 3 and Figure 4 As shown, the elastic seat 300 may be made of silicone and may have elastic properties and insulation properties. In some embodiments, the elastic seat 300 may include a body structure 330, a first recessed portion 310, and a second recessed portion 320 that are integrally arranged. Among them, the assembly cavity 301 may be formed on the side of the first recessed portion 310 facing the circuit board 200. The gas storage cavity 302 may be formed on the side of the second recessed portion 320 facing the circuit board 200. That is, both the assembly cavity 301 and the gas storage cavity 302 may be formed by the elastic seat 300 being recessed in a direction away from the circuit board 200. The body structure 330 may be located at the opening side of the first recessed portion 310 and the second recessed portion 320, and may be roughly in a flat plate structure. And the first recessed portion 310 and the second recessed portion 320 may be connected by the body structure 330. The guide column 600 may be located on the side of the first recessed portion 310 away from the circuit board 200.

[0043] In other embodiments, the elastic seat 300 may also be made of a flexible, insulating and dense material such as rubber.

[0044] In some embodiments, a gas guide groove 303 is further provided on one side of the body structure 330 facing the circuit board 200. One end of the gas guide groove 303 is connected to the assembly cavity 301, and the other end of the gas guide groove 303 is connected to the gas storage cavity 302. That is, the assembly cavity 301 and the gas storage cavity 302 are connected through the gas guide groove 303 to achieve gas transmission.

[0045] In some embodiments, at least one elastic ridge 340 is protruded from one side of the body structure 330 facing the circuit board 200. The elastic ridge 340 may also be made of silicone, and the elastic ridge 340 may be an integral structure with the body structure 330.

[0046] In other embodiments, the elastic rib 340 may be made of a flexible, insulating and dense material such as rubber. The elastic rib 340 may also be fixedly connected to the main structure 330 by gluing or hot melting.

[0047] In some embodiments, a side of the main body structure 330 facing the circuit board 200 is provided with an elastic ridge 340, and the elastic ridge 340 can be arranged along the edge of the main body structure 330 for a circle and present a closed ring structure. In the embodiment, the side of the elastic ridge 340 away from the main body structure 330 can abut against the circuit board 200, and the elastic ridge 340 is in a compressed state. Thereby, the sealing effect of the connection position between the elastic seat 300 and the circuit board 200 can be improved, the dustproof and waterproof effect can be improved, and the probability of water and dust entering the assembly cavity 301 can be reduced, thereby reducing the possibility of corrosion damage to the conductive contact 400 and the metal contact 220 due to water ingress, and extending the service life of the switch structure 1000.

[0048] In some embodiments, the side of the elastic ridge 340 facing away from the main body structure 330 may be an arc surface, which can further enhance the sealing effect of the connection position between the elastic seat 300 and the circuit board 200 .

[0049] In other embodiments, the cross section of the elastic ridge 340 perpendicular to the extending direction of the elastic ridge 340 may be an inverted triangle or an inverted trapezoid.

[0050] In other embodiments, the body structure 330 may also be provided with two, three, or five elastic ridges 340 protruding from one side facing the circuit board 200. The multiple elastic ridges 340 are arranged along the edge of the body structure 330, and the multiple elastic ridges 340 may be nested in sequence. Thus, the sealing path of the connection position between the elastic seat 300 and the circuit board 200 can be extended, further improving the dustproof and waterproof effect.

[0051] like Figure 3 and Figure 4As shown, in some embodiments, a boss 311 is further provided on the side of the first recessed portion 310 facing the circuit board 200. The boss 311 may be located at one end of the assembly cavity 301 away from the circuit board 200 and opposite to the metal contact 220 on the circuit board 200. The conductive contact 400 may be fixedly provided on the side of the boss 311 facing the circuit board 200 by gluing, injection molding or hot-melt connection. When the elastic seat 300 is not subjected to external force, the conductive contact 400 is spaced apart from the metal contact 220.

[0052] In some embodiments, the first recessed portion 310 may be tapered, such as a cone. The cross-sectional area of ​​the first recessed portion 310 near the circuit board 200 is greater than the cross-sectional area of ​​the first recessed portion 310 near the guide post 600. The cross-sectional areas of the first recessed portion 310 are perpendicular to the axial direction of the guide post 600, that is, the pressing direction acting on the first recessed portion 310.

[0053] In other embodiments, the first recessed portion 310 may also be in the form of a triangular pyramid, a quadrangular pyramid, or a hexagonal pyramid.

[0054] In some embodiments, an angle α is configured between the side wall of the first recessed portion 310 and the circuit board 200, wherein 55°≤α≤60°. Thus, the first recessed portion 310 can be elastically deformed under the pressure of the user, and smoothly drive the conductive contact 400 to approach and contact the metal contact 220 on the circuit board 200. At the same time, when the user cancels the pressing force applied to the first recessed portion 310, the first recessed portion 310 can also rebound and reset in a direction away from the circuit board 200 under the action of its own elastic force.

[0055] Exemplarily, in some embodiments, the angle α configured between the side wall of the first recess 310 and the circuit board 200 can be set to 55°, 56°, 56.5°, 57°, 57.5°, 58.8°, 59°, 59.2°, 59.5°, 60° or any other angle between 55° and 60°.

[0056] like Figure 3 , Figure 4 and Figures 10 to 12 As shown, in some embodiments, the side wall thickness n of the first recessed portion 310 can be set to 0.5 mm ≤ n ≤ 0.55 mm. Combined with the setting angle of the side wall of the first recessed portion 310 (i.e., the angle α), a more obvious sense of frustration can be generated during the operation of the switch structure 1000, wherein: , which can reach 45% to 65%, improving the user's operating feel and allowing the user to accurately perceive the operating progress when operating the switch structure 1000.

[0057] For example, in some embodiments, the sidewall thickness n of the first recessed portion 310 may be set to 0.5 mm, 0.51 mm, 0.52 mm, 0.54 mm, 0.55 mm, or any other value between 0.5 mm and 0.55 mm.

[0058] In some embodiments, the circuit board 200 may be a flexible printed circuit (FPC).

[0059] In some other embodiments, the circuit board 200 may be a rigid printed circuit board (PCB).

[0060] like Figure 3 As shown, the circuit board 200 further includes a substrate 210. It is understood that related circuits and other electronic devices may be arranged on the substrate 210. The metal contact 220 may be arranged on a side of the substrate 210 facing the elastic seat 300 and opposite to the conductive contact 400.

[0061] like Figure 3 , Figures 5 to 7 As shown, in some embodiments, the metal contact 220 may include a first contact structure 221 and a second contact structure 222. The first contact structure 221 and the second contact structure 222 are both electrically connected to the substrate 210, and the first contact structure 221 and the second contact structure 222 are spaced and insulated. When the conductive contact 400 contacts the metal contact 220, the conductive contact 400 may contact the first contact structure 221 and the second contact structure 222 at the same time, and the first contact structure 221 and the second contact structure 222 are electrically connected through the conductive contact 400.

[0062] In some embodiments, at least three first extension arms 2211 are disposed on one side of the first contact structure 221 facing the second contact structure 222, and the first extension arms 2211 are linear. The at least three first extension arms 2211 are parallel to each other, and a first gap 2212 is disposed between any two adjacent first extension arms 2211.

[0063] In some embodiments, the first contact structure 221 further includes a first connection portion 2213 . The first connection portion 2213 may be connected to one end of at least three first extension arms 2211 away from the second contact structure 222 , so that the first contact structure 221 may form an integrated structure.

[0064] In some embodiments, three first extension arms 2211 are disposed on one side of the first contact structure 221 facing the second contact structure 222, and two first gaps 2212 may be formed in the first contact structure 221. Accordingly, the first contact structure 221 may be in an E-shape.

[0065] At least two second extension arms 2221 are disposed on one side of the second contact structure 222 facing the first contact structure 221. The second extension arms 2221 are also linear. At least two second extension arms 2221 are parallel to each other and spaced apart. Accordingly, a second gap 2223 may be formed between any two adjacent second extension arms 2221. In addition, the second extension arm 2221 may also be parallel to the first extension arm 2211.

[0066] In some embodiments, the second contact structure 222 also includes a second connecting portion 2224 and two third extension arms 2222 . The two third extension arms 2222 can be separately arranged on both sides of at least two second extension arms 2221 as a whole, that is, the two third extension arms 2222 are arranged at the edge positions on both sides of the second contact structure 222 .

[0067] In some embodiments, the third extension arm 2222 may be substantially arcuate, and the side of the third extension arm 2222 facing the adjacent second extension arm 2221 may be configured as a straight edge and parallel to the second extension arm 2221. In addition, the third extension arm 2222 and the adjacent second extension arm 2221 are spaced apart, and a corresponding second gap 2223 may also be formed.

[0068] The second connection portion 2224 may be connected to one end of the two third extension arms 2222 away from the first contact structure 221, and one end of at least two second extension arms 2221 away from the first contact structure 221. Accordingly, the second contact structure 222 may form a structure similar to an E-shape, and the second contact structure 222 includes at least one E-shape.

[0069] In some embodiments, two second extension arms 2221 are disposed on a side of the second contact structure 222 facing the first contact structure 221. A second gap 2223 is formed between the two second extension arms 2221.

[0070] In the embodiment, the two second extension arms 2221 are inserted into the two first gaps 2212 in a one-to-one correspondence, and the second extension arms 2221 can be spaced apart from the first extension arms 2211. In addition, the second extension arms 2221 and the first connection portion 2213 are spaced apart, and the gap between the second extension arms 2221 and the first connection portion 2213 can be set as small as possible. In some embodiments, the gap between the second extension arms 2221 and the first connection portion 2213 can be set to 0.20 mm to 0.30 mm, and under the condition of ensuring that the first contact structure 221 and the second contact structure 222 are spaced apart and insulated, the first contact structure 221 and the second contact structure 222 can have a greater insertion depth. For example, in some embodiments, the gap between the second extension arm 2221 and the first connection portion 2213 may be set to 0.21 mm, 0.23 mm, 0.24 mm, 0.26 mm, 0.27 mm, 0.29 mm, 0.30 mm, or any other value between 0.20 mm and 0.30 mm.

[0071] Correspondingly, the three first extension arms 2211 can be inserted into the three second gaps 2223 in the second contact structure 222 in a one-to-one correspondence, and the first extension arm 2211 is spaced from the adjacent second extension arm 2221 and the third extension arm 2222. In addition, the first extension arm 2211 and the second connection portion 2224 are spaced apart, and the gap between the first extension arm 2211 and the second connection portion 2224 can be set as small as possible. In some embodiments, the gap between the first extension arm 2211 and the second connection portion 2224 can be set to 0.20 mm to 0.30 mm, and under the condition of ensuring that the first contact structure 221 and the second contact structure 222 are spaced and insulated, the first contact structure 221 and the second contact structure 222 can have a greater insertion depth. For example, in some embodiments, the gap between the first extension arm 2211 and the second connection portion 2224 can be set to 0.21 mm, 0.23 mm, 0.24 mm, 0.26 mm, 0.27 mm, 0.29 mm, 0.30 mm, or any other value between 0.20 mm and 0.30 mm.

[0072] In the embodiment, the assembled metal contact 220 may be roughly in a circular structure as a whole.

[0073] In other embodiments, the first contact structure 221 may be provided with four, five, or seven first extension arms 2211 on the side facing the second contact structure 222. The second contact structure 222 may be provided with three, four, or six second extension arms 2221 on the side facing the first contact structure 221, and the number of the second extension arms 2221 may be equal to the number of the first gaps 2212 in the first contact structure 221, that is, the shape of the second contact structure 222 may be complementary to the shape of the first contact structure 221. Both the first contact structure 221 and the second contact structure 222 may be provided with a plurality of E-shaped structures.

[0074] In the embodiment, the first contact structure 221 and the second contact structure 222 both include a plurality of E-shaped structures, so that, when the overall area of ​​the metal contact 220 is the same, the first extension arm 2211, the second extension arm 2221 and the third extension arm 2222 can be set as long as possible, so that the first contact structure 221 and the second contact structure 222 have a greater insertion depth. Furthermore, even if the conductive contact 400 is subjected to uneven force due to the uneven force on the keycap 140, it can be ensured that the conductive contact 400 can contact the first contact structure 221 and the second contact structure 222 respectively, so as to achieve conduction between the first contact structure 221 and the second contact structure 222, thereby increasing the probability of the first contact structure 221 and the second contact structure 222 being conducted through the conductive contact 400, thereby increasing the conduction yield of the switch structure 1000 and reducing the probability of poor contact. Among them, the direction in which the conductive contact 400 is subjected to uneven force can refer to the direction parallel to the length direction of the first extension arm 2211.

[0075] However, the contact structure in the related structure adopts an S-shaped structure, which makes the contact structure insertion depth shorter. When the conductive contact 400 is subjected to uneven force, the conductive contact 400 may only contact one of the contact structures, which is prone to poor contact problems. That is, the two relative contact structures cannot be connected through the conductive contact 400, affecting the normal use of the user.

[0076] like Figure 3 As shown, in some embodiments, the switch structure 1000 further includes a reinforcing plate 500, which may be disposed on a side of the substrate 210 away from the metal contact 220. The projections of the metal contact 220 and the reinforcing plate 500 on the same plane are located in the projection of the reinforcing plate 500, and the plane may be parallel to the reinforcing plate 500.

[0077] When the elastic seat 300 drives the conductive contact 400 to contact and abut the metal contact 220, each part of the metal contact 220 can be provided with corresponding support by the reinforcing plate 500, so that each part of the metal contact 220 is located on the same plane, so that each part of the metal contact 220 can contact the conductive contact 400, so that the metal contact 220 and the conductive contact 400 are fully in contact, ensuring that the first contact structure 221 and the second contact structure 222 are conductively connected through the conductive contact 400, thereby improving the conductive yield rate.

[0078] In some embodiments, the reinforcing plate 500 and the circuit board 200 may be bonded together by double-sided tape or glue.

[0079] like Figures 1 to 3 , Figure 8 and Fig. 9 As shown, the embodiment further provides a switch assembly 2000, which may include the switch structure 1000 provided in the embodiment. The switch assembly 2000 may be a switch assembly 2000 at the left handle position of a two-wheeled vehicle, or a switch assembly 2000 at the right handle position.

[0080] In addition, the switch assembly 2000 may include at least one of the function switches 2100 such as a dimmer switch, a cruise control switch, a menu switch, a mode switch, a steering switch, a horn, a heating switch, a double flash switch, a start / stop switch, and a lighting switch. In addition, at least one function switch 2100 may include the switch structure 1000 provided in the embodiment.

[0081] In some embodiments, the function switch 2100 may include the switch structure 1000 provided in one or more embodiments at the same time. For example, the steering switch may include three switch structures 1000, and the horn may include one switch structure 1000.

[0082] In some embodiments, the switch assembly 2000 may include two adjacently arranged functional switches 2100, and the two functional switches 2100 each include a switch structure 1000. The elastic seat 300 in the two functional switches 2100 may be an integral structure and share the same air storage cavity 302, that is, the two assembly cavities 301 in the two functional switches 2100 are connected to the same air storage cavity 302. The two assembly cavities 301 may be separately arranged on the peripheral side of the air storage cavity 302. In addition, the cover plate 130 in the two functional switches 2100 may be an integral structure or separately arranged. The circuit board 200 in the two functional switches 2100 may also be an integral structure or separately arranged.

[0083] In other embodiments, the switch assembly 2000 may include three, four, or six switch structures 1000 disposed adjacent to each other, and the elastic seats 300 in the multiple switch structures 1000 are all integral structures and share the same air storage cavity 302. The assembly cavities 301 in the multiple switch structures 1000 may be disposed on the peripheral side of the air storage cavity 302, and each assembly cavity 301 is connected to the air storage cavity 302.

[0084] In some embodiments, the keycap 140 in the switch structure 1000 can be swingably arranged relative to the housing 110. And the keycap 140 can swing to both sides around its own rotation axis. In some embodiments, the keycap 140 is swingably connected to the side of the cover plate 130 away from the elastic seat 300. In the embodiment, the switch structure 1000 may also include a positioning assembly 700, and the positioning assembly 700 can maintain the keycap 140 in the middle position when not subjected to external force. Among them, the positioning assembly 700 may include a positioning member 710 and an elastic member 720. In the embodiment, the bracket 120 may be provided with a positioning groove 121 on the side facing the circuit board 200, and the bracket 120 may be misaligned with the circuit board 200. An extension block 132 opposite to the bracket 120 may be protruding on one side of the cover plate 130, and an assembly groove 133 facing the side of the bracket 120 may be provided in the extension block 132, and the assembly groove 133 may be arranged opposite to the positioning groove 121. The positioning member 710 and the elastic member 720 are installed in the assembly groove 133, and the elastic member 720 abuts between the positioning member 710 and the groove bottom of the assembly groove 133. When the switch structure 1000 is not subjected to external force, the elastic member 720 can be in a natural extension state or a compression state. The end of the positioning member 710 away from the elastic member 720 can protrude relative to the opening structure of the assembly groove 133 and be limited in the positioning groove 121 on the bracket 120. When the keycap 140 of the switch structure 1000 is forced to swing to one side, the elastic member 720 can be squeezed and the elastic member 720 can store corresponding elastic potential energy. When the external force acting on the keycap 140 is removed, the other parts of the switch structure 1000 can be reset under the elastic force of the elastic member 720 and maintained in the middle position. In some embodiments, the elastic member 720 can be a spring, a spring sheet or an elastic column. The positioning member 710 can be a positioning column, a positioning bead or a positioning block.
