Description

Technical Field

[0001] This utility model relates to the field of transportation vehicle technology, and in particular to a side support switch, a side support assembly, and an electric vehicle. Background Technology

[0002] Traditional side stand switches, as an important safety component in two-wheeled vehicles such as motorcycles and electric vehicles, are mainly used to detect the status of the side stand and control the start and stop of the motor. Existing side stand switches generally employ a mechanical contact design, achieving circuit control through the principle of physical contact to open and close the circuit. Their typical structure includes a spring-driven movable contact and a fixed contact. When the side stand is raised or lowered, a mechanical linkage moves the movable contact, thus closing or opening the circuit.

[0003] During long-term use, mechanical contacts will experience metal wear due to repeated friction, leading to oxidation of the contact surface and increased contact resistance. Environmental factors such as road dust, rainwater erosion, or lubricant seepage will further aggravate the contamination and corrosion of the contact surface. Switching components are also susceptible to vibration interference when the vehicle is bumpy, which may cause contact bounce or mis-contact. All of the above factors can cause unstable signal transmission, and in severe cases, lead to complete failure. Utility Model Content

[0007] The magnetic rotor rotates in conjunction with the retaining shell. The magnetic rotor is configured to trigger the reed switch when rotating relative to the retaining shell. The retaining shell has a double-layer encapsulation structure. The inner cavity of the double-layer encapsulation structure contains the reed switch and is filled with inert gas.

Detailed Implementation

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] The first aspect of this utility model is to provide a side-support switch, such as Figures 1 to 3 As shown, it includes a magnetic rotor 1, a retaining shell 2, a reed switch 3, and a double-layer encapsulation structure 4. The magnetic rotor 1 is used to connect to the side support body 5, and the reed switch 3 is used to connect to the circuit system.

[0035] The magnetic rotor 1 rotates with the retaining shell 2. The magnetic rotor 1 is configured to trigger the reed switch 3 when rotating relative to the retaining shell 2. The retaining shell 2 is provided with a double-layer encapsulation structure 4. The inner cavity of the double-layer encapsulation structure 4 is provided with the reed switch 3 and filled with inert gas. The outer surface of the double-layer encapsulation structure 4 is provided with a metal coating layer.

[0036] When the side-support switch provided in the above embodiment is in use, the side-support body 5 moves, which drives the magnetic rotor 1 to rotate. The magnetic field generated by the magnetic rotor 1 around the reed switch 3 changes, thereby triggering the reed switch 3 inside the holding shell 2 through the change of magnetic field, realizing the power-on and power-off of the circuit system. The double-layer encapsulation structure 4 outside the reed switch 3 can improve the corrosion resistance and high-voltage resistance of the reed switch 3. Specifically, the inert gas can be used to protect the reed switch 3, prevent its oxidation and suppress electric arc, and the metal coating layer can improve the corrosion resistance of the reed switch 3 and extend its service life. Compared with mechanical contacts, the above method is not affected by metal wear, and environmental factors and vehicle vibration have less impact on the reliable operation of the side-support switch, which is conducive to ensuring the stability of signal transmission and improving vehicle safety.

[0037] In alternative implementations, such as Figure 3 As shown, the double-layer packaging structure 4 includes an outer layer 41 and an inner layer 42 disposed inside the outer layer 41. The inner layer 42 is provided with a reed switch 3 and filled with inert gas. There is a vacuum chamber between the inner layer 42 and the outer layer 41. The outer surface of the outer layer 41 is provided with a metal coating layer.

[0038] The inner layer 42 is located within the space enclosed by the outer layer 41. The inert gas and the reed switch 3 are located within the space enclosed by the inner layer 42. The inert gas (such as nitrogen, argon, etc.) is chemically stable and does not easily react with other substances. Filling the inner layer 42 with inert gas can effectively prevent the reed switch 3 from oxidation or other chemical corrosion, thereby extending its service life. In addition, an electric arc may be generated when the contacts of the reed switch 3 close and open. Filling with inert gas can effectively suppress these arcs and protect the contacts from damage.

[0039] Metal coatings (such as gold, silver, nickel, etc.) typically offer good corrosion and oxidation resistance, protecting the outer layer 41 in harsh environments and extending the overall lifespan of the package structure. They also improve solderability, facilitating the mounting of the outer layer 41 onto the circuit board.

[0040] In an optional implementation, the metal coating layer is produced using a nickel plating process.

[0041] The outer layer 41 and the inner layer 42 may, but are not limited to, be made of glass.

[0042] In addition, both ends of the reed switch 3 have metal leads. The outer layer 41 and the inner layer 42 are both mounted on the metal leads. The parts of the metal leads that pass through the outer layer 41 and the inner layer 42 are sealed by the encapsulation process, and the outer layer 41, the inner layer 42 and the reed switch 3 are assembled into a whole.

[0043] In alternative implementations, such as Figure 1 As shown, the side support switch also includes a wire assembly 6, one end of which extends into the retaining housing 2 and is electrically connected to the two pins of the reed switch 3, and the other end extends out of the retaining housing 2.

[0044] The purpose of the wiring assembly 6 is to connect one end of the reed switch 3 to the positive terminal of the vehicle circuit and the other end to the load. When the reed switch 3 senses a magnetic field, the circuit is turned on, and the vehicle circuit system starts to power on and off. This ensures the timeliness and accuracy of signal transmission, guarantees the normal operation of vehicle-related functions, and leverages the crucial role of the side stand switch in the vehicle system.

[0045] The wiring assembly 6 includes a first wire and a second wire. The first wire connects one pin of the reed switch 3 to the positive terminal of the vehicle circuit, and the second wire connects the other pin of the reed switch 3 to the load.

[0046] In an optional embodiment, the housing 2 is further provided with a resistor 7 connected in series with the reed switch 3. The resistor 7 can limit the current and extend the life of the reed switch 3.

[0047] In an optional embodiment, the housing 2 is provided with sealant.

[0048] The sealant completely encapsulates the reed switch 3, the wire assembly 6, and the solder joints, forming a waterproof barrier at the wire exit point. This barrier protects against external moisture erosion and ensures that the reed switch 3 and the wire assembly 6 maintain good working condition.

[0049] In alternative implementations, such as Figure 2 As shown, the retaining shell 2 has a mating hole 21, and the magnetic rotor 1 includes a mating part 11. The mating part 11 extends into the mating hole 21, and there is a gap between the outer peripheral surface of the mating part 11 and the mating hole 21 to prevent wear from occurring during the relative rotation of the retaining shell 2 and the magnetic rotor 1.

[0050] The mating part 11 is cylindrical with a circular cross-section, and the mating hole 21 is a through hole with a circular cross-section. The mating part 11 is inserted into the mating hole 21 and rotates with it. During assembly, the gap between the mating part 11 and the mating hole 21 can be controlled within the range of 0.1-0.3 mm. This design improves the reliability and stability of the side-support switch, effectively reduces signal deviations or mechanical failures caused by gap fluctuations, significantly enhances the performance of the side-support switch, extends its service life, and provides strong support for the stable operation of the equipment.

[0051] In an optional embodiment, a magnet is provided inside the magnetic rotor 1. Specifically, the magnet is internally injection molded and installed inside the magnetic rotor 1. During installation, the distance between the magnet and the reed switch 3 is controlled so that the reed switch 3 is within the optimal sensing range, ensuring that the reed switch 3 can accurately and sensitively respond to changes in the magnetic field, thereby achieving stable and reliable switching action.

[0052] A second aspect of this utility model provides a side support assembly, which includes the aforementioned side support switch.

[0053] The side support assembly provided in the second aspect of this utility model has the side support switch provided in the first aspect of this utility model, and thus has all the beneficial effects of the side support switch provided in the first aspect of this utility model.

[0054] In alternative implementations, such as Figure 5 As shown, the side support assembly also includes a side support body 5, a mounting plate 8, a first connector 9, and a second connector 10; the side support body 5 and the mounting plate 8 are rotatably connected by the first connector 9, and the rotation axis of the side support body 5 relative to the mounting plate 8 coincides with the rotation axis of the magnetic rotor 1 relative to the retaining shell 2; the magnetic rotor 1 is connected to the side support body 5, the retaining shell 2 is connected to the mounting plate 8, and the second connector 10 passes through the retaining shell 2 and the magnetic rotor 1 and is connected to the first connector 9.

[0055] During operation, the magnetic rotor 1 retracts or extends along with the side support body 5, rotating synchronously with the swing of the side support body 5 while keeping the shell 2 stationary. As the magnetic rotor 1 rotates, the magnetic field generated by the magnetic rotor 1 outside the reed switch 3 changes. When the external magnetic field strength of the reed switch 3 reaches a specific threshold, the two magnetic reeds inside the reed switch 3 are quickly magnetized. The attraction between the magnetic poles causes the reeds to contact, the circuit is instantly turned on, and the load immediately starts working. Once the external magnetic field disappears, the magnetic reeds quickly return to their initial separated state due to their own characteristics, the circuit is immediately broken, and the load stops running. The entire process is responsive, precise, and reliable.

[0056] The first connector 9 can be a stepped screw, which tightly and securely connects the side support body 5 and the mounting plate 8 into one unit, effectively reducing the risk of loosening and building a solid foundation. The second connector 10 can be a fastening screw, with a threaded hole at the end of the stepped screw. The second connector 10 passes through the retaining shell 2 and the magnetic rotor 1 and can be connected to the threaded hole to achieve axial positioning of the retaining shell 2 and the magnetic rotor 1.

[0057] In an optional embodiment, the magnetic rotor 1 is snapped into the side support body 5 to facilitate installation of the magnetic rotor 1.

[0058] In the above embodiments, the magnetic rotor 1 is locked onto the side support body 5, which allows the magnetic rotor 1 to rotate synchronously with the side support body 5, thereby stably monitoring the extension and retraction status of the side support body 5.

[0059] Specifically, such as Figure 4 As shown, the magnetic rotor 1 has a slot 12 on the side facing the side support body 5. The slot 12 includes a first limiting edge 121 and a second limiting edge 122. During assembly, the end of the side support body 5 is inserted into the slot 12, and the first limiting edge 121 and the second limiting edge 122 abut against the two sides of the end of the side support body 5, thereby allowing the magnetic rotor 1 to rotate together with the side support body 5.

[0060] In an optional embodiment, the retaining shell 2 is engaged with the mounting plate 8 to prevent the retaining shell 2 from rotating relative to the mounting plate 8, thereby ensuring the stability of the position of the reed switch 3.

[0061] Specifically, the mounting plate 8 is provided with a limiting protrusion 81, and the retaining shell 2 is recessed with a limiting groove 22. During assembly, the limiting protrusion 81 can be engaged with the limiting groove 22, thereby preventing the magnetic rotor 1 from rotating along with the retaining shell 2 as it rotates with the side support body 5. The above-mentioned limiting structure, in conjunction with the second connecting member 10, can ensure that the retaining shell 2 maintains precise positional accuracy during operation, unaffected by vibration and external force interference, ensuring stable and displacement-free operation.

[0062] The limiting protrusion 81 can be columnar, and the limiting groove 22 can be formed directly from the side wall of the retaining shell 2 toward the middle of the retaining shell 2, so as to facilitate the engagement of the limiting groove 22 with the limiting protrusion 81.

[0063] Additionally, after installation, the reed switch can be tested to verify the accuracy of the reed switch 3 under different operating conditions, check whether the circuit's on / off state is stable and meets the preset standards, and ensure that the switch can operate stably and reliably in actual applications.

[0064] The third aspect of this utility model provides an electric vehicle, which includes a circuit system and the aforementioned side stand switch or side stand assembly. The reed switch 3 is connected to the circuit system to enable the electric vehicle's circuit system to be powered on and off.

[0065] In an optional implementation, the side stand switch can also be linked with the electric vehicle's battery management system. For example, when the side stand body 5 is unfolded, it automatically enters a low-power mode and restores full power supply when it is retracted, thus optimizing the energy consumption management of the electric vehicle.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
