[0041] Electric vehicles are widely used as a means of short-distance transportation. Electric vehicles include two-wheeled electric bicycles, three-wheeled electric vehicles, electric scooters, electric mopeds, and electric motorcycles. The movement of an electric vehicle is controlled by a switch located on the handlebars. This switch controls the vehicle's start, forward and reverse movements, gear shifting, lights, horn, etc. This results in a large number of mechanical switches within the control switch, each requiring at least two wires to be electrically connected to a corresponding component (motor, lights, horn, etc.). This leads to a large variety and number of components within the control switch, reducing assembly efficiency.

[0042] This application provides a control switch for an electric vehicle, which can be used in any type of electric vehicle controlled by a handlebar. (See also...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a schematic diagram of the control switch provided in this application. Figure 2 This is a front view structural diagram of the control switch provided in this application. Figure 3 This is an exploded view of the control switch provided in this application. Figure 4 Schematic diagram of the disassembled structure of some components in the control switch provided in this application Figure 1 , Figure 5 Provided for this application Figure 2 A cross-sectional view along the AA direction. The control switch provided in the embodiments of this application will be described below with reference to examples in the accompanying drawings.

[0043] The control switch provided in this embodiment includes: a housing 1, a circuit board 21, a conductive element 22, and an operating element 3; wherein, the housing 1 encloses a receiving cavity, and the housing 1 has a mounting structure 13 and a first through hole 14, the mounting structure 13 can be used to install the control switch on an electric vehicle; the circuit board 21 is disposed in the receiving cavity and can be electrically connected to the controller of the electric vehicle, and the circuit board 21 has a control contact 211; the conductive element 22 is movably disposed in the receiving cavity and corresponds to the control contact 211, and the conductive element 22 can conduct current; the operating element 3 is movably disposed in the housing 1 and extends through the first through hole 14 to a position corresponding to the conductive element 22, and the operating element 3 drives the conductive element 22 to move.

[0044] Optionally, the operating element 3 moves relative to the housing 1, which can cause the conductive element 22 to abut or separate from the control contact 211.

[0045] In this embodiment of the application, the housing 1 can be configured as a structure including a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 can be assembled by means of snaps, screws or welding, so as to form a receiving cavity by the first housing 11 and the second housing 12.

[0046] For example, a mounting structure 13 adapted to the handlebars of an electric vehicle can be provided on the housing 1 to mount the housing 1 (control switch) to the electric vehicle. The mounting structure 13 can be a clamp, a slot, or a fastening strap, etc. For example, the mounting structure 13 can be a clamp, which is set on the handlebars, and the control switch is clamped in the clamp to realize the control switch is set on the handlebars; the mounting structure 13 can also be a slot set on the handlebars, and the control switch is correspondingly provided with a buckle, and the buckle and the slot are engaged to realize the control switch is set on the handlebars.

[0047] In another example, a first through hole 14 matching the operating element 3 can be provided on the housing 1 so that the operating element 3 can be mounted on the housing 1 through the first through hole 14.

[0048] In this embodiment, a circuit board 21 can be disposed in the control switch. The circuit board 21 typically includes a substrate layer, a conductive layer, a functional layer, and auxiliary structures. The substrate layer is typically made of glass fiber reinforced epoxy resin or phenolic resin paperboard, providing mechanical support and insulation. The conductive layer is formed by etching copper foil to create a network of wires for electrical connections; the copper foil can be electrolytic copper foil or rolled copper foil. The functional layer includes a solder mask layer, a silkscreen layer, pads, and vias. The solder mask layer is typically a green or blue protective layer covering the surface of the conductive layer, preventing short circuits and oxidation. The silkscreen layer displays component numbers, polarity markings, and assembly information. The pads are used to solder component leads, and the vias enable interlayer connections between the layers of the circuit board 21.

[0049] For example, the circuit board 21 can be fixed in the receiving cavity by fasteners such as screws, or the circuit board 21 can be inserted into the receiving cavity by a slot 56 provided on the shell wall of the housing 1.

[0050] In another example, the structural shape of the circuit board 21 can be determined based on the number of operating elements 3 set in the control switch, the position of each operating element 3 on the housing 1, and the shape of the receiving cavity. For example, the position of the control contact 211 on the circuit board 21 can be set according to the position of the operating elements 3. The control contact 211 can be a printed circuit with its two ends adjacent to each other and separated by a gap. The two ends of the printed circuit can be electrically connected by the conductive element 22, thereby turning on the control contact 211 and generating an electrical signal (such as voltage or current).

[0051] As another example, structures or components that can be electrically connected to other electrical devices can be provided on the circuit board 21. For example, wires can be soldered onto the circuit board 21 and extended to the outside of the housing 1 to facilitate electrical connection between the circuit board 21 and the controller of the electric vehicle. A wireless transmitter can also be provided on the circuit board 21 to electrically connect the circuit board 21 to the controller via wireless transmission (such as Bluetooth transmission).

[0052] In this embodiment, a conductive element 22 can be disposed within the receiving cavity. The conductive element 22 can be a device capable of conducting current. The conductive element 22 and the circuit board 21 form a circuit assembly 2. For example, the conductive element 22 can be made of silicone conductive particles, a dome switch, a metal conductive contact, etc. The conductive element 22 can be positioned directly opposite the control contact 211, with a gap between the conductive element 22 and the control contact 211. The conductive element 22 can be slidably disposed within the receiving cavity, allowing it to move relative to the control contact 211.

[0053] In this embodiment, the movement of the conductive member 22 relative to the control contact 211 can be operated by the operating member 3. For example, a first through hole 14 can be provided on the housing 1, and the position of the first through hole 14 corresponds to the control contact 211. The shape of the first through hole 14 matches the operating member 3, so that the operating member 3 can be inserted into the housing 1 through the first through hole 14, thereby so that a part of the operating member 3 is located in the receiving cavity and corresponds to the conductive member 22, while the other part of the operating member 3 is located outside the housing 1.

[0054] For example, the movement of the operating element 3 relative to the housing 1 can be sliding, rotating, pressing, or flicking. Depending on the different movement modes of the operating element 3, the way the operating element 3 is positioned on the housing 1 can vary. For example, the operating element 3 can be slidably mounted on the housing 1, or rotatedly mounted on the housing 1. Thus, when the user operates the operating element 3, causing it to move relative to the housing 1, the operating element 3 can drive the conductive element 22 to move relative to the control contact 211. This allows the conductive element 22 to abut against the control contact 211 to make the control contact 211 conductive, or to separate the conductive element 22 from the control contact 211 to make the control contact 211 disconnect, thereby enabling the control switch to generate a control signal.

[0055] The control switch provided in this application embodiment has a housing 1 that encloses a cavity, allowing other components of the control switch to be installed within the cavity, thus providing protection for these components. A mounting structure 13, compatible with an electric vehicle, is provided on the housing 1, enabling the control switch to be accurately and stably installed on the electric vehicle. A circuit board 21 and a conductive element 22 are provided within the cavity. By setting the number and position of control contacts 211 on the circuit board 21, the control switch can generate multiple control signals. Simultaneously, an operating element 3 is movably positioned on the housing 1 at a position corresponding to the conductive element 22, facilitating user operation of the control switch. Compared to control switches in related technologies, which typically have multiple metal contacts and springs, and multiple wires electrically connecting the metal contacts and springs, the control switch provided in this application embodiment generates control signals through the conductive element 22 and the circuit board 21. This allows multiple switches to be integrated onto the same circuit board 21, reducing the number of components in the control switch, simplifying the assembly process, improving assembly efficiency, and / or facilitating automated production.

[0056] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, the control switch also includes a seal 4, which is located in the receiving cavity and between the circuit board 21 and the operating member 3. The seal 4 has a reset part 41, which is located between the conductor 22 and the operating member 3. The conductor 22 is fixed to the reset part 41, and the reset part 41 can deform to drive the conductor 22 to move away from the control contact 211.

[0057] In this embodiment, a seal 4 can be provided inside the control switch to seal the circuit board 21. The seal 4 can be made of a material with good insulating properties, such as silicone, rubber, or plastic.

[0058] For example, the shape of the seal 4 can be set according to the shape of the circuit board 21. For instance, the seal 4 can be set as a bag-like structure with an opening, and the circuit board 21 can be placed inside the bag-like seal 4 to achieve a seal on the circuit board 21. A portion of the seal 4 can be located between the circuit board 21 and the operating member 3 to isolate the circuit board 21 from the first through hole 14 on the housing 1, etc.

[0059] In another example, a reset part 41 can be provided on the seal 4, and the reset part 41 can be positioned on the seal 4 at a position corresponding to the control contact 211, that is, the reset part 41 also corresponds to the operating member 3. For example, the reset part 41 can be a protrusion in the shape of a cone or cylinder, which extends from the seal 4 away from the control contact 211. A groove can also be provided on the side of the protrusion facing the control contact 211, and the conductive member 22 can be fixed at the bottom of the groove away from the control contact 211. The reset part 41 and the seal 4 can be an integral structure, or the reset part 41 can be fixedly connected to the seal 4 by means of bonding, welding, etc. The reset part 41 has good elastic deformation properties. For example, when the seal 4 and the reset part 41 are an integral structure and the seal 4 is made of silicone, the reset part 41 has elastic deformation capability. In this way, by moving the operating member 3 relative to the housing 1, the reset part 41 can be moved relative to the control contact 211, thereby driving the conductive member 22 fixed in the reset part 41 to move relative to the control contact 211.

[0060] In the above embodiments, since a sealing element 4 is provided between the circuit board 21 and the operating element 3, the circuit board 21 can be isolated and sealed by the sealing element 4, thereby reducing the impact of moisture, dust, etc. on the circuit board 21. Furthermore, a reset part 41 is provided on the sealing element 4, which can deform to drive the conductive element 22 to separate from the control contact 211. This reduces the need for structures on the conductive element 22 to guide its movement relative to the control contact 211, and helps to reduce the number of components in the control switch.

[0061] In some possible embodiments of this application, such as Figure 3 , Figure 4 and Figure 5 As shown, the control switch also includes a bracket assembly 5, which is disposed in the receiving cavity. The bracket assembly 5 surrounds and forms a sealed cavity that matches both the circuit board 21 and the seal 4. The circuit board 21 and the seal 4 are both located in the sealed cavity. The area of ​​the bracket assembly 5 corresponding to the reset part 41 has a second through hole 54, through which the operating member 3 can abut against the reset part 41.

[0062] In this embodiment, a bracket assembly 5 can be provided inside the control switch to support and install some components within the control switch. For example, the bracket assembly 5 can be configured as a closed box-shaped structure to form a sealed cavity. The bracket assembly 5 can be integrally formed with the housing 1 or it can be a separate structure. The shape and size of the bracket assembly 5 can be adjusted according to the space within the cavity. The bracket assembly 5 can be made of the same material as the housing 1 or a different material, such as metal or engineering plastic.

[0063] For example, the shape of the sealing cavity can be set according to the shape of the circuit board 21 and the seal 4 so that both the circuit board 21 and the seal 4 can be installed in the sealing cavity. For example, the seal 4 can be set as an approximately sheet-like structure, and the seal 4 can be stacked with the circuit board 21 in the sealing cavity.

[0064] In another example, a second through hole 54 corresponding to each reset part 41 can be provided on the bracket assembly 5. When the reset member is circular, the second through hole 54 can be a circular through hole. The inner diameter of the second through hole 54 is larger than the outer diameter of the reset part 41 to reduce friction between the reset part 41 and the bracket assembly 5. The reset part 41 can extend out of the second through hole 54, or the portion of the operating member 3 corresponding to the reset part 41 can extend into the second through hole 54, so that the operating member 3 can abut against the reset part 41 through the second through hole 54.

[0065] In the above embodiment, since a support assembly 5 is provided within the receiving cavity, the support assembly 5 can provide support and a mounting base for the circuit board 21, the seal 4, etc., reducing the movement of the circuit board 21, the seal 4, etc. within the receiving cavity and improving the stability of the circuit board 21, etc. Furthermore, a second through hole 54 corresponding to the reset part 41 is provided on the support assembly 5, allowing the operating member 3 to abut against the reset part 41 through the second through hole 54, thus reducing the impact on the sealing performance of the receiving cavity.

[0066] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, the bracket assembly 5 includes a support member 51 and a cover member 52. The support member 51 has a receiving groove 53 that matches both the circuit board 21 and the seal 4. The circuit board 21 and the seal 4 are stacked in the receiving groove 53. The cover member 52 covers the opening of the receiving groove 53 to form a sealed cavity. A second through hole 54 is provided in the cover member 52.

[0067] In this embodiment, the support assembly 5 can be configured to include a support member 51 and a cover member 52. The support member 51 can be configured as a box-shaped structure with an opening, that is, the support member 51 has a receiving groove 53. The shape and structure of the receiving groove 53 match the circuit board 21 and the seal 4, so that the circuit board 21 and the seal 4 can be stacked in the receiving groove 53. The cover member 52 can be configured as an approximately flat plate structure, and the shape and structure of the cover member 52 match the opening of the receiving groove 53. The cover member 52 can be placed over the opening of the receiving groove 53 to form a sealed cavity by the cover member 52 and the support member 51.

[0068] For example, a second through hole 54 can be provided on the cover plate 52, that is, the circuit board 21 is located at the bottom of the receiving groove 53, and the seal 4 is located on the side of the circuit board 21 near the opening of the receiving groove 53, so that the reset part 41 can pass through the second through hole 54 to the outside of the bracket assembly.

[0069] In the above embodiments, the support assembly is configured to include a support member 51 and a cover plate 52, which facilitates the processing of the support assembly. Furthermore, the support member 51 is provided with a receiving groove 53, within which the circuit board 21 and the sealing member 4 can be stacked. The sealing member 4 can then shield and seal the circuit board 21, and the cover plate 52 can further seal the receiving groove 53, thus placing the circuit board 21 within a relatively sealed space.

[0070] In some possible embodiments of this application, such as Figure 5 As shown, the sealing member 4 has a raised ring 42 on the side facing the cover plate member 52. The raised ring 42 surrounds the sealing member 4 around the edge of the sealing member 4. Along the covering direction of the cover plate member 52 and the carrier member 51, the raised ring 42 abuts against the cover plate member 52 and is in an interference fit. The reset part 41 is located in the area enclosed by the raised ring 42 on the sealing member 4.

[0071] In this embodiment of the application, when the sealing member 4 is stacked on the side of the circuit board 21 near the cover plate 52, a protruding ring 42 can be provided on the side of the sealing member 4 facing the cover plate 52. The protruding ring 42 surrounds the sealing member 4 along the edge of the sealing member 4, that is, the protruding ring 42 is a complete ring. Figure 4 As shown, all reset parts 41 can be located within the area enclosed by the protruding ring 42 on the seal 4.

[0072] For example, along the covering direction of the cover plate 52 and the carrier 51 ( Figure 5The arrangement direction Z shown allows the height of the convex ring 42 to be greater than the distance between the surface of the seal 4 and the cover plate 52. Thus, during the process of covering the cover plate 52 onto the support member 51, the cover plate 52 first abuts against the convex ring 42, and then the cover plate 52 presses against the convex ring 42, causing the convex ring 42 to be compressed and deformed along the covering direction. This ensures a tight fit between the convex ring 42 and the cover plate 52, meaning an interference fit between the convex ring 42 and the cover plate 52 along the covering direction.

[0073] In the above embodiment, since the sealing member 4 has a protruding ring 42 on the side facing the cover plate member 52, after the assembly of the cover plate member 52 and the carrier member 51 is completed, the protruding ring 42 can be tightly abutted against the cover plate member 52, thereby forming a sealed space between the cover plate member 52 and the sealing member 4, which can prevent water vapor, dust and other substances from reaching the circuit board 21 through the sealing member 4, which is beneficial to reducing the impact of the environment on the circuit board 21.

[0074] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, the sealing member 4 has a first sealing groove (not shown) on the side facing the circuit board 21. The first sealing groove surrounds the sealing member 4 around its edge. A filler (not shown) is provided in the first sealing groove and is connected to the circuit board 21. The reset part 41 is located in the area enclosed by the first sealing groove on the sealing member 4. Alternatively, the sealing member 4 has a stepped structure 43 on the side facing the cover plate 52. The stepped structure 43 surrounds the sealing member 4 around its edge. The stepped structure 43 and the inner wall of the bearing member 51 enclose a second sealing groove. A filler (not shown) is provided in the second sealing groove and is connected to the cover plate 52. The reset part 41 is located in the area enclosed by the stepped structure 43 on the sealing member 4.

[0075] In this embodiment, a filler can be provided between the seal 4 and the bracket assembly to further seal the receiving groove 53. For example, a sealing groove for receiving the filler can be provided on the seal 4 to accommodate and fix the filler. The filler can be selected from sealant, sealing ring, etc.

[0076] For example, such as Figure 4 As shown, it can be applied to seal 4 (such as...) Figure 4The sealing member 4, located below the circuit board 21, has a first sealing groove on its surface facing the circuit board 21. The first sealing groove is an annular groove surrounding the sealing member 4. For example, two annular protrusions can be provided on the sealing member 4, each annular protrusion surrounding the edge of the sealing member 4, with a gap between the two annular protrusions, thereby forming the first sealing groove. The reset part 41 can be placed in the area formed by the first sealing groove on the sealing member 4. In this way, during the process of attaching the sealing member 4 to the circuit board 21, the edge of the first sealing groove can abut against the circuit board 21, thereby sealing the control contact 211 on the circuit board 21 and the conductive part 22 provided in the reset part 41 between the first sealing groove and the circuit board 21.

[0077] Another example, such as Figure 5 As shown, a stepped structure 43 can be provided on the side of the seal 4 facing the cover plate 52. The stepped structure 43 is a structure that sinks downward along the thickness direction (arrangement direction Z) of the seal 4 at the edge of the seal 4, and the cross-section of the stepped structure 43 is approximately "L-shaped". Furthermore, the stepped structure 43 can be arranged around the seal 4, so that after the seal 4 is placed in the receiving groove 53 on the support member 51, the stepped structure 43 and the inner wall of the support member 51 can jointly enclose and form a second sealing groove.

[0078] In another example, fillers can be provided in both the first and second sealing grooves. The height of the filler in the first sealing groove along the closing direction of the cover plate 52 and the carrier 51 is greater than the distance between the seal 4 and the circuit board 21, so as to press the filler against the first sealing groove and the circuit board 21 through the cover plate 52 or the carrier 51. The height of the filler in the second sealing groove along the closing direction is greater than the distance between the bottom of the stepped structure 43 and the cover plate 52, so as to press the filler against the second sealing groove and the cover plate 52 through the cover plate 52.

[0079] In the above embodiments, since a first sealing groove is provided on the sealing member 4 or a second sealing groove is formed between the sealing member 4 and the carrier member 51, fillers can be provided in both the first and second sealing grooves. Thus, the conductor 22 and the control contact 211, etc., can be sealed in a sealed environment by the filler in the first sealing groove. The circuit board 21 can be sealed between the receiving groove 53 of the carrier member 51 and the sealing member 4 by the second sealing groove. This helps to reduce the influence of the environment on the circuit board 21 and improves the reliability of the circuit board 21, etc.

[0080] In some possible embodiments of this application, such as Figure 4As shown, one of the carrier 51 and the cover plate 52 is provided with a buckle 55, and the other of the carrier 51 and the cover plate 52 is provided with a slot 56 corresponding to the buckle 55. The carrier 51 and the cover plate 52 are fixedly connected by the cooperation of the buckle 55 and the slot 56.

[0081] In this embodiment, the carrier 51 and the cover plate 52 can be fixedly connected by a snap-fit ​​mechanism. For example, a protruding buckle 55 can be provided on the edge of the carrier 51, and a matching groove 56 can be provided on the cover plate 52 in the area corresponding to the buckle 55. Alternatively, a protruding buckle 55 can be provided on the edge of the cover plate 52, and a matching groove 56 can be provided on the carrier 51 in the area corresponding to the buckle 55. Along the circumference of the cover plate 52, multiple pairs of matching buckles 55 and grooves 56 can be provided on the carrier 51 and the cover plate 52, so that the cover plate 52 and the carrier 51 can be fixedly connected by the cooperation of the buckles 55 and the grooves 56.

[0082] In the above embodiments, since the carrier 51 and the cover plate 52 are respectively provided with matching buckles 55 and slots 56, the carrier 51 and the cover plate 52 can be fixedly connected by the cooperation of the buckles 55 and the slots 56. Moreover, during the assembly of the carrier 51 and the cover plate 52, the cover plate 52 can be placed on the carrier 51 and pressed together, which helps to simplify the assembly steps of the cover plate 52 and the carrier 51.

[0083] In some possible embodiments of this application, reference is made to Figure 6 , Figure 6 Schematic diagram of the disassembled structure of some components in the control switch provided in this application Figure 2 .like Figure 4 and Figure 6 As shown, the control switch also includes a connector 6, one end of which is electrically connected to the circuit board 21, and the other end of which extends through the bracket assembly to the outside of the sealed cavity. The connector 6 is used for electrical connection with the controller.

[0084] In this embodiment, a connector 6 can be provided in the control switch to electrically connect the circuit board 21 to the controller of the electric vehicle. For example, multiple connector pins can be provided on the circuit board 21, and each pin can be soldered to the printed circuit on the circuit board 21 for electrical connection. A pin header connector 62 matching the connector pins can also be provided. The connector pins can be plugged into and electrically connected to the pin header 61, and the pin header 61 and the pin header connector 62 constitute the connector 6. Correspondingly, a through hole matching the connector 6 can be provided on the carrier 51 or the cover plate 52, so that the connector 6 can extend to the outside of the sealed cavity through the through hole. A sealing element (such as sealant) can also be provided between the pin header connector 62 and the through hole to seal the sealed cavity.

[0085] In the above embodiments, since the connector 6 is provided on the circuit board 21, the steps of soldering multiple wires separately can be reduced during the assembly of the control switch. This not only facilitates the electrical connection between the control switch and the controller, but also reduces the assembly steps of the control switch.

[0086] In some possible embodiments of this application, such as Figure 5 and Figure 6 As shown, the operating member 3 is slidably disposed on the housing 1 and / or the bracket assembly 5, and a first limiting structure 58 is provided between the operating member 3 and the housing 1 and / or the bracket assembly 5. The first limiting structure 58 can limit the sliding position of the operating member 3 relative to the housing 1.

[0087] In this embodiment, the operating element 3 can be slidably disposed in the control switch relative to the housing 1, and the sliding operating element 3 drives the conductive element 22 to move relative to the control contact 211. For example, the operating element 3 can be configured as a structure including a trigger element 31 and an outer trim element 32, or the operating element 3 can be configured as a single integral structure.

[0088] For example, a groove matching the trigger 31 can be provided inside the housing 1, or a groove matching the trigger 31 can be provided on the cover plate 52. In this way, the trigger 31 can be slidably disposed between the housing 1 and the cover plate 52 via the groove. The sliding direction Y of the trigger 31 relative to the housing 1 is perpendicular or nearly perpendicular to the closing direction of the cover plate 52 and the bearing member 51.

[0089] In another example, a plug-in post can be provided on the trigger 31, and a plug-in hole matching the plug-in post can be provided on the outer trim 32. The outer trim 32 and the trigger 31 can then be plugged and fixed together by the plug-in post and the plug-in hole. The plug-in post can pass through the first through hole 14, so that the outer trim 32 is located outside the housing 1, and the trigger 31 is located inside the receiving cavity.

[0090] In another example, a first limiting structure 58 can be provided between the housing 1, the support assembly 5, and the operating member 3 to limit the sliding position of the operating member 3 relative to the housing 1. For example, a first stop can be provided on the cover plate 52, and a second stop corresponding to the first stop can be provided on the trigger member 31. The first and second stops extend along the arrangement direction Z to limit the sliding position of the operating member 3 relative to the housing 1.

[0091] In the above embodiment, since the operating member 3 is slidably mounted on the housing 1, it is convenient to drive the reset part 41 (conductive member 22) to move relative to the control contact 211 by sliding the operating member 3 relative to the housing 1. Furthermore, a first limiting structure 58 is provided between the operating member 3 and the housing 1, and between the operating member 3 and the support assembly 5, which allows the operating member 3 to slide relative to the reset part 41 to an accurate position, thereby improving the accuracy of operating the operating member 3, and further enabling the conductive member 22 to accurately abut or separate from the control contact 211.

[0092] In some possible embodiments of this application, such as Figure 6 As shown, the first limiting structure 58 includes a first limiting post 581 and at least two first limiting grooves 582. The first limiting post 581 is disposed on one of the operating member 3 and the support assembly 5, and the first limiting post 581 extends along the arrangement direction Z of the conductor 22 and the operating member 3. The first limiting grooves 582 are disposed on the other of the operating member 3 and the support assembly 5, and at least two first limiting grooves 582 are arranged along the sliding direction Y of the operating member 3 relative to the housing 1. At least one of the first limiting post 581 and the first limiting grooves 582 can reciprocate in a direction that satisfies a parallel relationship with the arrangement direction Z.

[0093] In this embodiment, a first limiting post 581 can be provided on the trigger member 31, and correspondingly, a first limiting groove 582 corresponding to the first limiting post 581 can be provided on the cover plate member 52, or a first limiting groove 582 corresponding to the first limiting post 581 can be provided inside the housing 1. Alternatively, a first limiting groove 582 can be provided on the trigger member 31, and correspondingly, a first limiting post 581 corresponding to the first limiting groove 582 can be provided on the cover plate member 52, or the first limiting post 581 can be provided inside the housing 1. Both the first limiting post 581 and the first limiting groove 582 extend along the Z-direction. Thus, during the sliding process of the operating member 3 relative to the housing 1, the first limiting post 581 can slide out or in from the first limiting groove 582 to limit the sliding position of the operating member 3 relative to the housing 1.

[0094] For example, the number of first limiting grooves 582 can be set according to the position where the operating member 3 needs to slide relative to the housing 1. For example, when the two reset parts 41 are moved by one operating member 3, three first limiting grooves 582 can be continuously set on the cover plate 52 along the sliding direction Y, so that the operating member 3 can be stably stopped relative to the housing 1 in three positions. The operating member 3 can abut against one reset part 41 in two positions, and the operating member 3 does not abut against either reset part 41 in the third position.

[0095] In another example, a compression spring can be provided between the first limiting post 581 and the trigger member 31, so that the first limiting post 581 can move relative to the first limiting groove 582 along the arrangement direction Z by the compression spring. Alternatively, the first limiting groove 582 (provided on a separate part) can be slidably disposed on the cover plate 52 along the arrangement direction Z, and a compression spring can be provided between the first limiting groove 582 and the cover plate 52, so that the first limiting groove 582 can move relative to the first limiting post 581 along the arrangement direction Z.

[0096] In the above embodiments, since the first limiting structure 58 is configured to include a first limiting post 581 and a first limiting groove 582, the operating member 3 can be slidably fixed (not allowed to slide arbitrarily) on the housing 1 along the sliding direction Y by sliding the first limiting post 581 among multiple first limiting grooves 582. Furthermore, at least one of the first limiting post 581 and the first limiting groove 582 can reciprocate in a direction parallel to the arrangement direction Z. During the process of controlling the sliding of the operating member 3 relative to the housing 1, the first limiting post 581 and the first limiting groove 582 can also generate movement along the arrangement direction Z, which can reduce the resistance of the operating member 3 sliding relative to the housing 1 and facilitate user operation.

[0097] In some possible embodiments of this application, such as Figure 5 As shown, the operating member 3 has a trigger structure 311 on the side facing the conductor 22. During the process of the operating member 3 sliding relative to the housing 1 in the sliding direction Y, the conductor 22 can move along the arrangement direction Z of the control contact 211 and the conductor 22 under the drive of the trigger structure 311. The arrangement direction Z and the sliding direction Y are perpendicular to each other.

[0098] In this embodiment, a trigger structure 311 can be provided on the operating member 3 to drive the reset part 41 to move relative to the control contact 211. For example, a spring block can be provided on the trigger member 31, which is connected to the trigger member 31 by a compression spring. A stop block corresponding to the spring block can be provided on the cover plate 52. During the sliding process of the operating member 3 relative to the housing 1, the spring block can move towards the trigger member 31 under the restriction of the stop block. After the spring block separates from the stop block, the spring block moves towards the reset part 41 under the action of the compression spring to press the reset part 41 towards the control contact 211.

[0099] For example, the trigger structure 311 may also include a protrusion extending along the arrangement direction Z of the conductor 22 and the operating member 3. At least one end of the protrusion has a guide surface 312 along the sliding direction Y, and the guide surface 312 forms an obtuse angle with the sliding direction Y. For instance, a protruding protrusion may be provided on the surface of the trigger member 31 facing the circuit board 21, and the reset part 41 may be pressed by the protrusion. In the case where one operating member 3 corresponds to two reset parts 41, two protrusions may be provided on the trigger member 31, and each of the two protrusions may drive one reset part 41 to move along the arrangement direction Z.

[0100] In another example, a guide surface 312 can be provided on the side where the protrusion contacts the reset part 41. For example, the guide surface 312 can be set as an inclined surface with an angle of 150° to 170° with the sliding direction Y. In this way, during the process of the guide surface 312 contacting the reset part 41, the force exerted by the guide surface 312 on the reset part 41 along the arrangement direction Z gradually increases.

[0101] In the above embodiments, by setting the trigger structure 311 to include a protrusion, the structure of the operating member 3 can be simplified. Furthermore, the protrusion is provided with an inclined guide surface 312, which helps to reduce the resistance encountered by the operating member 3 along the sliding direction Y during the contact and relative sliding process between the operating member 3 and the conductor 22 or the reset part 41, thus facilitating the operation of the operating member 3.

[0102] In some possible embodiments of this application, reference is made to Figure 7 , Figure 7 Schematic diagram of the disassembled structure of some components in the control switch provided in this application Figure 3 The operating element 3 is movably disposed on the housing 1 and / or the support assembly 5, and a second limiting structure 59 is provided between the operating element 3 and the housing 1 and / or the support assembly 5, which can limit the movement position of the operating element 3 relative to the housing 1.

[0103] In this embodiment, the operating member 3 can be operated by rotating relative to the housing 1. For example, a rotating shaft can be provided on the operating member 3, and correspondingly, a shaft hole matching the rotating shaft can be provided on the housing 1, or a shaft hole matching the rotating shaft can be provided on the bracket assembly 5. Alternatively, a shaft hole can be provided on the operating member 3, and correspondingly, a rotating shaft matching the shaft hole can be provided on the housing 1, or a rotating shaft matching the shaft hole can be provided on the bracket assembly 5. In this way, the operating member 3 can be rotatably mounted on the housing 1 or the bracket assembly 5 through the cooperation of the rotating shaft and the shaft hole.

[0104] For example, such as Figure 7 As shown, control contacts 211 can be provided on both sides of the circuit board 21, that is, operating elements 3 can be provided on both the front and back of the housing 1. For example, three operating elements 3 can be provided on the first housing 11, and one operating element 3 can be provided on the second housing 12 (e.g. Figure 7 The operating member 3 shown below. A guide assembly 9 can be provided on the operating member 3 located on the second housing 12, and a pusher 8 can be provided on the guide assembly 9, so that the operating member 3 drives the pusher 8 to move, thereby causing the pusher 8 to drive the reset part 41 (conductor 22) to move relative to the control contact 211. For example, the guide assembly 9 can be configured to include a guide shell 91 and a guide cover 92, and through holes matching the pusher 8 can be provided on the guide shell 91 and the guide cover 92 to allow the pusher 8 to pass through the guide shell 91 and the guide cover 92, and to close the guide shell 91 and the guide cover 92.

[0105] In another example, a second limiting structure 59 can be provided between the housing 1, the support assembly 5, and the operating member 3 to limit the rotational position of the operating member 3 relative to the housing 1. For example, a third stop can be provided inside the housing 1, and a fourth stop corresponding to the third stop can be provided on the operating member 3. The third and fourth stops extend relative to each other along the arrangement direction Z to limit the rotational angle of the operating member 3 relative to the housing 1 through the abutment of the third and fourth stops.

[0106] In this embodiment, the operating member 3 can be operated by pressing and moving relative to the housing 1. For example, a pressing through hole matching the operating member 3 can be provided on the housing 1, and the extending direction of the pressing through hole is parallel or nearly parallel to the arrangement direction Z of the circuit board 21 and the conductive member 22. In this way, by pressing the operating member 3 along the arrangement direction Z, the operating member 3 can move relative to the housing 1 by pressing and moving relative to the housing 1, thereby causing the reset part 41 to move relative to the control contact 211. Alternatively, the operating member 3 can move relative to the housing 1 by pressing and moving relative to the housing 1, thereby causing the pusher 8 to move along the arrangement direction Z, and then causing the pusher 8 to move relative to the control contact 211.

[0107] For example, a fifth stop can be provided on the wall of the pressing through hole, and a sixth stop corresponding to the fifth stop can be provided on the operating member 3. Both the fifth and sixth stops extend radially along the pressing through hole and are arranged in the Z-direction. In this way, during the pressing of the operating member 3, the movement of the operating member 3 relative to the housing 1 can be limited until the sixth and fifth stops abut against each other.

[0108] In the above embodiment, since the operating member 3 is movably mounted on the housing 1, it is convenient to move the reset part 41 (conductive member 22) relative to the control contact 211 by moving the operating member 3 relative to the housing 1. Furthermore, a second limiting structure 59 is provided between the operating member 3 and the housing 1, and between the operating member 3 and the support assembly 5, which allows the operating member 3 to move to an accurate position relative to the reset part 41, thereby improving the accuracy of operating the operating member 3, and further enabling the conductive member 22 to accurately abut or separate from the control contact 211.

[0109] In some possible embodiments of this application, such as Figure 7 As shown, the second limiting structure 59 includes a second limiting post 591 and at least two second limiting grooves 592. The second limiting post 591 is disposed on one of the operating member 3 and the support assembly 5, and extends in a direction parallel to the arrangement direction Z of the conductor 22 and the operating member 3. The second limiting grooves 592 are disposed on the other of the operating member 3 and the support assembly 5, and at least two second limiting grooves 592 are arranged in the rotation direction of the operating member 3 relative to the housing 1. At least one of the second limiting post 591 and the second limiting groove 592 is capable of reciprocating in a direction parallel to the arrangement direction Z.

[0110] In this embodiment, the operating member 3 can be rotatably mounted on the housing 1, the support assembly 5, or the guide assembly 9. A second limiting post 591 can be provided on the operating member 3, and correspondingly, a second limiting groove 592 corresponding to the second limiting post 591 can be provided on the support member 51 or the guide assembly 9, or a second limiting groove 592 corresponding to the second limiting post 591 can be provided inside the housing 1. Alternatively, a second limiting groove 592 can be provided on the operating member 3, and correspondingly, a second limiting post 591 corresponding to the second limiting groove 592 can be provided on the support member 51 or the guide assembly 9, or the second limiting post 591 can be disposed inside the housing 1. Both the second limiting post 591 and the second limiting groove 592 extend along the Z-direction. Thus, during the rotation of the operating member 3 relative to the housing 1, the second limiting post 591 can slide out or in from the second limiting groove 592 to limit the rotational position of the operating member 3 relative to the housing 1.

[0111] For example, the number of second limiting grooves 592 can be set according to the position where the operating member 3 needs to rotate relative to the housing 1. For example, when the two reset parts 41 are moved by one operating member 3, the two second limiting grooves 592 can be continuously set on the guide assembly 9 along the rotation direction so that the operating member 3 can be stably stopped at two positions relative to the housing 1. The operating member 3 can drive a pusher 8 to abut against the corresponding reset part 41 at the two positions.

[0112] In another example, a compression spring can be provided between the second limiting post 591 and the operating member 3, so that the second limiting post 591 can move relative to the second limiting groove 592 along the arrangement direction Z by the compression spring. Alternatively, the second limiting groove 592 (provided on a separate part) can be slidably disposed on the carrier member 51 or the guide assembly 9 along the arrangement direction Z, and a compression spring can be provided between the second limiting groove 592 and the carrier member 51 or the guide assembly 9, so that the second limiting groove 592 can move relative to the second limiting post 591 along the arrangement direction Z.

[0113] In the above embodiments, since the second limiting structure 59 is configured to include a second limiting post 591 and a second limiting groove 592, the operating member 3 can be movably fixed (without arbitrary rotation) to the housing 1 along the rotation direction by sliding the second limiting post 591 among multiple second limiting grooves 592. Furthermore, at least one of the second limiting post 591 and the second limiting groove 592 can reciprocate in a direction parallel to the arrangement direction Z. During the process of controlling the rotation of the operating member 3 relative to the housing 1, the second limiting post 591 and the second limiting groove 592 can also generate movement along the arrangement direction Z, which can reduce the resistance to the rotation of the operating member 3 relative to the housing 1 and facilitate user operation.

[0114] In some possible embodiments of this application, such as Figure 4 As shown, the bracket assembly 5 has a guide hole 57 corresponding to the reset part 41. The control switch also includes a pressing post 7 that matches the guide hole 57. The pressing post 7 passes through the guide hole 57 and abuts against the reset part 41. During the movement of the operating member 3 relative to the housing 1, the operating member 3 can drive the pressing post 7 to move relative to the control contact 211.

[0115] In this embodiment, the operating member 3 can drive the pressing column 7 to move relative to the reset part 41, so that the reset part 41 drives the conductive member 22 to move relative to the control contact 211.

[0116] For example, a guide hole 57 corresponding to the reset part 41 can be provided on the carrier 51 or the cover plate 52, and the pressing post 7 can be inserted into the guide hole 57. A clearance fit can be used between the guide hole 57 and the pressing post 7, that is, there is a small and precise gap between the guide hole 57 and the pressing post 7, so that the pressing post 7 can move along the guide hole 57, while reducing the offset and displacement of the pressing post 7. The gap between the guide hole 57 and the pressing post 7 can be adjusted according to the smoothness and damping force required for the movement of the pressing post 7. The end of the pressing post 7 facing the operating member 3 can protrude from the guide hole 57, and the end of the pressing post 7 facing the reset part 41 contacts the reset part 41.

[0117] In the above embodiment, since a guide hole 57 is opened in the area of ​​the bracket assembly 5 corresponding to the reset part 41, and the pressing post 7 is inserted through the guide hole 57, when the operating member 3 moves, the radial movement of the pressing post 7 can be constrained and guided by the guide hole 57, so that the pressing post 7 always moves along a straight trajectory perpendicular to the circuit board 21. This can reduce the skew, shaking or jamming of the pressing post 7 during the movement, improve the stability of the pressing member in making the control contact 211 turn on or off, and facilitate the installation of the pressing post 7 on the bracket assembly 5.

[0118] In some possible embodiments of this application, such as Figure 5 As shown, the sealing member 4 has a fixing part 44 on the side facing the circuit board 21. The fixing part 44 matches the circuit board 21, and the circuit board 21 is fixed to the sealing member 4 by the fixing part 44.

[0119] In this embodiment, when the seal 4 and the circuit board 21 are stacked, the circuit board 21 can be fixed to the seal 4 by the fixing part 44. The fixing part 44 can be provided on the edge of the seal 4 facing the circuit board 21. For example, the fixing part 44 can be provided as a hook-shaped structure that extends from the edge of the seal 4 toward the center of the seal 4. If multiple hook-shaped structures are provided on the seal 4 along the circumference, and multiple hook-shaped structures are used as fixing parts 44, the circuit board 21 can be fixed to the seal 4 by multiple hook-shaped structures.

[0120] In the above embodiments, since a fixing part 44 is provided on the sealing member 4, during the assembly of the circuit board 21 and the sealing member 4, the circuit board 21 can be fixedly connected to the sealing member 4 through the fixing part 44 to form an integral part, which facilitates the gripping of automated equipment or the manual assembly, thereby improving the assembly efficiency of the circuit board 21 and the sealing member 4 in the bracket assembly 5.
