Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a steering switch and a vehicle. Background Technology

[0002] A turn signal switch is a device used by the driver to control the vehicle's turn signals. The driver uses the turn signals to clearly communicate their driving intentions to other road users.

[0003] In related technologies, turn signals are prone to problems such as not being able to reset in time after operation or getting stuck in a certain turning position after long-term use, which affects the driver's normal control of the turn signals. Utility Model Content

[0004] In order to solve the problem that turn signals may be difficult to reset after long-term use in related technologies, this application provides a turn signal switch and a vehicle.

[0005] To achieve the above objectives, this application provides a turn signal switch, including a housing, a guide, an actuating element, and a reset element. The housing has a cavity, and an opening communicating with the cavity is provided on the housing. The guide is hingedly mounted within the housing and has switch contacts. Multiple switch inserts are distributed within the cavity along the rotation direction of the guide, and when the guide rotates, the switch contacts can contact the switch inserts. The actuating element is coaxially hinged to the guide and mounted within the housing, connected to the guide and capable of driving the guide to rotate synchronously. The actuating element has a sliding groove, and the hinge shaft at the hinge point is inserted into the sliding groove and can slide along the opening direction of the sliding groove. A reset bead is rolled at the end of the actuating element. The reset element has a reset surface facing the actuating element, and the reset surface includes a first inclined surface and a second inclined surface with opposite inclination directions. The first and second inclined surfaces are continuously arranged, and the connection point is a limiting portion. The reset bead can abut against the reset surface.

[0006] Furthermore, the guide member is provided with a positioning part, which is located on the same side of the hinge with the switch contact, and the positioning part and the switch contact are symmetrically arranged with respect to the hinge.

[0007] Furthermore, the positioning part includes a positioning groove and a positioning bead. The positioning groove is formed on the guide member, and the opening of the positioning groove faces the inner wall of the housing. The positioning bead is installed in the positioning groove by a spring. Multiple positioning steps are formed on the housing along the rotation direction of the guide member, and the positioning bead can abut against the positioning steps.

[0008] Furthermore, the multiple positioning steps are arranged in a one-to-one correspondence with the multiple switch inserts, so that when the positioning bead is located on different positioning steps, the switch contact can abut against different switch inserts.

[0009] Furthermore, the guide member has a through groove located between the positioning part and the switch contact; the toggle member has a protrusion on the side facing the guide member, and the protrusion is inserted into the through groove.

[0010] Furthermore, the through groove includes a first groove segment and a second groove segment, the second groove segment being disposed on one side of the first groove segment near the edge of the guide member. The first groove segment is quadrilateral, the second groove segment is triangular, and there is a smooth transition between the first groove segment and the second groove segment.

[0011] Furthermore, the actuating element has a straight groove, the opening of which faces the reset element. The reset bead is mounted in the straight groove by a spring, and the reset bead can abut against the reset surface.

[0012] Furthermore, the switch insert is L-shaped, and at least a portion of the switch insert is located on the inner wall of the housing, parallel to the guide member. A mounting plate is provided on the side of the guide member facing the switch insert, and the switch contact is spring-mounted to the mounting plate so that the switch contact can abut against the switch insert.

[0013] Furthermore, one end of the toggle extends from the opening to the outside of the housing, and a switch button is provided on the end of the toggle extending to the outside of the housing.

[0014] This application also provides a vehicle, including a vehicle body and a turn signal switch as described in any of the above embodiments, the turn signal switch being used to control the turn signals of the vehicle body.

[0015] With the above technical solution, when using the turn signal switch of this application, the operator controls the toggle element, causing the guide element to rotate. During the movement of the guide element, the switch contacts on the guide element move accordingly, contacting one of the multiple switch plates, thereby connecting the circuit corresponding to the switch plate in contact with the switch contact, and the corresponding turn signal works normally. To change the illuminated turn signal, continue rotating the guide element, causing the switch contacts to move and contact another switch plate.

[0016] When the turn signal switch is in its initial position, the reset ball at the end of the actuating element abuts against the limiting portion of the reset surface. As the actuating element rotates the guide element, the reset ball slides onto the first or second inclined plane. When the turn signal switch needs to be reset, the operator presses the actuating element. Because the hinge shaft of the actuating element is inserted into the sliding groove and can move along the groove, the force applied to the actuating element is transmitted through the actuating element to the reset ball, and then through the reset ball to the first or second inclined plane. The reaction force of the first or second inclined plane on the reset ball causes the reset ball to move along the inclined plane and slide to the limiting portion at its lowest point, thus resetting the actuating element, which in turn resets the guide element.

[0017] The turn signal switch of this application achieves reset by pressing the toggle switch through the cooperation of the reset bead and the reset surface. The transmission is simple, the cooperation is reliable, and it can ensure stability during long-term use.

[0025] This embodiment provides a turn signal switch to solve the problem in related technologies that turn signal switches may be difficult to reset after long-term use.

[0026] Please see Figures 1 to 3This embodiment provides a turn signal switch, including a housing 100, a guide member 200, a toggle member 300, and a reset member 400. A cavity 110 is formed within the housing 100, and an opening communicating with the cavity 110 is formed on the housing 100. The guide member 200 is hingedly mounted within the housing 100 and is provided with switch contacts 210. Multiple switch inserts 220 are distributed within the cavity 110 along the rotation direction of the guide member 200. When the guide member 200 rotates, it can drive the switch contacts 210 to contact the switch inserts 220. The actuating element 300 and the guide element 200 are coaxially hinged and installed inside the housing 100. The actuating element 300 is connected to the guide element 200 and can drive the guide element 200 to rotate synchronously. A sliding groove 310 is provided on the actuating element 300, and the hinge shaft at the hinge point is inserted into the sliding groove 310 and can slide along the opening direction of the sliding groove 310. A reset bead 320 is rolled at the end of the actuating element 300. A reset surface is provided on the reset element 400 facing the actuating element 300. The reset surface includes a first inclined surface 410 and a second inclined surface 420 with opposite inclination directions. The first inclined surface 410 and the second inclined surface 420 are continuously arranged and the connection point is a limiting part 430. The reset bead 320 can abut against the reset surface.

[0027] Specifically, when using the turn signal switch of this embodiment, in the initial state, the turn signal switch is not operated and is in a neutral position. The switch contact 210 on the guide member 200 is not in contact with any switch insert 220, or is in contact with the switch insert 220 in a standby state, and all turn signals remain off. The reset bead 320 at the end of the toggle member 300 abuts precisely against the limiting portion 430 of the reset surface. The limiting portion 430, as the lowest point, provides stable support for the reset bead 320, keeping the entire switch in its initial balanced position, ready to respond to driver operation at any time.

[0028] In operation, the driver moves the actuating element 300 in either the forward or reverse direction. The actuating element 300 rotates under force, and because it is coaxially hinged with the guide element 200, it causes the guide element 200 to rotate synchronously. As the guide element 200 rotates, the switch contact 210 on the guide element 200 moves accordingly and contacts the corresponding switch insert 220 in the cavity 110. The circuit is connected, and the turn signal on the corresponding side of the vehicle begins to flash.

[0029] During the toggle operation, as the toggle member 300 rotates, the reset bead 320 slides from the limiting part 430 onto the first inclined surface 410 or the second inclined surface 420, and rolls along the inclined surface, depending on the toggle direction.

[0030] In the reset state, when the vehicle completes a turn or lane change and the driver turns off the turn signal, the actuating element 300 is manually pressed. The pressing force is transmitted through the actuating element 300 to the reset bead 320 at its end. The reset bead 320 applies pressure to the first inclined surface 410 or the second inclined surface 420 it contacts. The inclined surface decomposes this pressure into two components: one component resists the pressing force, and the other component pushes the reset bead 320 downwards along the inclined surface. Thus, driven by the reaction force of the inclined surface, the reset bead 320 rolls downwards along the inclined surface and eventually slides back to the limiting portion 430 located at the lowest point of the two inclined surfaces. Since the hinge shaft of the actuating element 300 is inserted into the sliding groove 310, the shaft can move along the groove when pressed, providing the necessary radial displacement space for the rolling of the reset bead 320 and the return of the actuating element 300. When the reset bead 320 returns to the limiting portion 430, the actuating element 300 and the guide 200 automatically return to their initial positions under structural constraints. When the switch contact 210 on the guide 200 disengages from the switch insert 220 or returns to the switch insert 220 in the initial standby state, the turn signal returns to the standby state and the light turns off.

[0031] In this embodiment, the turn switch's reset mechanism does not rely entirely on a passive spring; instead, it is actively driven by a pressing action. Utilizing the mechanical force amplification principle of the inclined plane, it provides a reliable reset driving force. Furthermore, the reset action is achieved through the interaction of the reset ball 320 and the inclined plane. The rolling motion of the reset ball 320 reduces movement resistance, allowing for smooth rolling even with slight wear or dust, exhibiting extremely strong anti-jamming capability. The rolling contact between the reset ball 320 and the inclined plane, combined with the precise positioning of the limiting part 430, ensures that each reset accurately returns to the same initial position, resulting in high consistency and good stability.

[0032] In one embodiment, exemplarily, such as Figures 2 to 4 As shown, a positioning part 230 is provided on the guide member 200. The positioning part 230 and the switch contact 210 are located on the same side of the hinge, and the positioning part 230 and the switch contact 210 are symmetrically arranged relative to the hinge. During vehicle operation, continuous vibration may cause slight wobbling of the guide member 200, resulting in "fretting wear" between the contact and the insert, ultimately leading to contact failure. The positioning part 230, as an additional auxiliary support point, together with the hinge shaft, forms a triangular stable structure. The dual support points of the hinge shaft and the positioning part 230 are more resistant to external vibration than a single support point. Even in a vibrating environment, the wobbling amplitude of the guide member 200 is effectively limited by the positioning part 230, protecting the stability of the contact and improving the durability of the switch in high-vibration environments.

[0033] In one embodiment, exemplarily, such as Figures 2 to 4As shown, the positioning part 230 includes a positioning groove 231 and a positioning bead 232. The positioning groove 231 is formed on the guide member 200, and the opening of the positioning groove 231 faces the inner wall of the housing 100. The positioning bead 232 is installed in the positioning groove 231 by a spring. Multiple positioning steps 120 are formed on the housing 100 along the rotation direction of the guide member 200, and the positioning bead 232 can abut against the positioning steps 120. Under the action of the spring, the positioning bead 232 always has a tendency to pop outward, pressing against the inner wall of the housing 100. The positioning steps 120 on the housing 100 form multiple uneven surfaces. When the guide member 200 rotates, the positioning bead 232 is driven by the guide member 200 to roll on the positioning steps 120. Furthermore, after the positioning bead 232 moves to a positioning step 120, it can cooperate with the positioning step 120 to restrict the guide member 200 to the current position.

[0034] In this embodiment, each time the positioning bead 232 rolls from one positioning step 120 and falls into the next, a noticeable change in force and a sound are generated. The spring pushes the positioning bead 232 out, causing it to strike the positioning step 120 with a "click" sound and vibration, providing feedback to the driver. This allows the driver to accurately determine whether the turn signal switch is in position without looking at the instrument panel, relying solely on touch. Furthermore, the unevenness between the different positioning steps 120 provides a retaining force for the positioning bead 232, preventing the switch from accidentally sliding due to vehicle vibrations.

[0035] Turn signals typically need to operate stably in three discrete positions: "left turn," "right turn," and "off," and cannot remain in an ambiguous intermediate state. Each positioning step 120 corresponds to a preset working position, and the spring force ensures that the positioning ball 232 is firmly engaged in each positioning step 120, achieving mechanical self-locking. Thus, when the positioning ball 232 falls into a positioning step 120, it means that the guide member 200 has rotated into position, and the switch contact 210 on it must be in full contact with the corresponding switch insert 220. This avoids a state of incomplete or poor contact between the switch contact 210 and the switch insert 220. Furthermore, the cooperation between the positioning ball 232 and the positioning step 120 ensures that it returns to the same physical position after each operation, guaranteeing the consistency of circuit on / off, and ensuring the reliability of the electrical connection through mechanical limiting.

[0036] In one embodiment, exemplarily, such as Figures 3 to 5As shown, multiple positioning steps 120 are correspondingly arranged with multiple switch plates 220, so that when the positioning bead 232 is located on different positioning steps 120, the switch contact 210 can abut against different switch plates 220. The contact between the switch contact 210 and the plate requires sufficient positive pressure and the correct alignment angle; otherwise, it will lead to high contact resistance, overheating, or even a loose connection. The positioning steps 120 provide precise axial and circumferential limits for the positioning bead 232. Since the positioning part 230 and the switch contact 210 are symmetrically arranged, the precise positioning of the positioning bead 232 directly determines the precise position of the switch contact 210, ensuring that the switch contact 210 always contacts the plate with the optimal angle and pressure, achieving surface contact rather than point contact. Furthermore, the contact state between the contact and the plate is exactly the same in every operation, resulting in stable contact resistance and reliable electrical performance. This avoids the contact slipping over the plate or contacting the insulation area between two plates, improving the stability and safety of signal transmission.

[0037] In one embodiment, exemplarily, such as Figures 2 to 4 As shown, a through groove 240 is provided on the guide member 200, located between the positioning part 230 and the switch contact 210; a protrusion is provided on the side of the actuating member 300 facing the guide member 200, and the protrusion is inserted into the through groove 240. Traditional connection methods, such as direct rigid fixing or end-face friction transmission, are prone to failure due to wear, loosening, or stress concentration during long-term use. In this embodiment, power is transmitted through the surface contact between the sidewall of the protrusion and the sidewall of the through groove 240. Compared with point contact or line contact, surface contact disperses stress and reduces the pressure per unit area. The contact surface wears evenly during repeated sliding, preventing localized rapid wear-through and significantly extending the service life of the transmission components.

[0038] The through groove 240 is elongated with a certain allowance along its length, allowing the protrusion to slide within it to a limited extent. During assembly, even if there is a slight deviation in the relative position between the actuating element 300 and the guide element 200, the protrusion can move within the through groove 240 and automatically find the correct position, achieving smooth assembly. Furthermore, the cooperation between the protrusion and the through groove 240 can compensate for the cumulative dimensional and geometric tolerances between multiple parts such as the hinge shaft, housing 100, actuating element 300, and guide element 200, reducing the requirements for molds and processing equipment.

[0039] In one embodiment, exemplarily, such as Figures 2 to 4As shown, the through slot 240 includes a first slot segment 241 and a second slot segment 242, with the second slot segment 242 located on one side of the first slot segment 241 near the edge of the guide member 200. The first slot segment 241 is quadrilateral, and the second slot segment 242 is triangular, with a smooth transition between the first slot segment 241 and the second slot segment 242. After resetting, the turn signal switch must return to its neutral initial position with absolute accuracy to ensure that the left and right turn signal circuits are completely disconnected, providing a consistent starting point for the next turn operation. If the initial position is inaccurate, it may result in false lighting, unclear gear shifting, or reset failure. In this embodiment, the triangular second slot segment 242 serves as the initial positioning cavity. During the reset process of the toggle member 300, the protrusion on it is guided into the second slot segment 242, and the convergence characteristic of the triangle forces the protrusion to move towards its narrowest point.

[0040] In this way, regardless of the direction from which the bump enters the triangular area, it will be guided by the hypotenuse to a unique vertex position, allowing the guide block to accurately reset. The width at the vertex of the triangle is the smallest, providing the tightest fit with the bump and eliminating the wobble of the toggle member 300 and guide member 200 in their initial positions. This ensures that after each reset, the rotation angle of the guide member 200 is highly consistent, providing an accurate starting point for the next operation.

[0041] The first slot 241 serves as the main drive channel. During normal operation, the protrusion slides within this slot, causing the guide 200 to rotate. The second slot 242, located at the edge, serves as a dedicated reset channel. There are no sharp edges between the two slots, forming a smooth connection. During normal operation, the protrusion primarily moves within the first slot 241, avoiding interference from the triangular structure with the main drive. When the actuating element 300 is pressed to reset, the hypotenuse of the triangle guides the protrusion to slide naturally into the second slot 242. This smooth transition ensures that the protrusion does not get stuck or experience any jerking when moving between the two slots, making the entire reset process smooth and seamless.

[0042] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the actuating element 300 has a straight groove, with the groove opening facing the reset element 400. The reset bead 320 is mounted in the straight groove by a spring and can abut against the reset surface. When the actuating element 300 is pressed, the reset bead 320 needs to roll smoothly and linearly along the inclined surface of the reset surface and eventually slide back to the limiting part 430. If the installation of the reset bead 320 lacks constraints, its movement may deviate from the predetermined trajectory, resulting in jamming or uneven force. The straight groove acts as a linear guide, restricting the degree of freedom of movement of the reset bead 320; the reset bead 320 can only move along the length of the straight groove. This ensures that the movement of the reset bead 320 strictly follows the designed path and cooperates with the inclined surface of the reset surface. This prevents the reset bead 320 from lateral displacement or rotational instability during rolling.

[0043] The reset bead 320 is mounted in the straight groove by a spring. The spring constantly applies an outward pushing force to the reset bead 320, ensuring that the reset bead 320 remains in contact with the reset surface. Regardless of whether the switch is in the initial, operating, or reset state, the reset bead 320 maintains contact with the reset surface and will not disengage or create gaps. Furthermore, the spring's elasticity compensates for manufacturing tolerances, assembly errors, and minor wear after long-term use, ensuring that even after prolonged use of the turn signal switch, the reset bead 320 can still effectively act on the inclined surface, extending the service life of this embodiment.

[0044] When the driver presses the actuating element 300, the force is transmitted through the actuating element 300 to the bottom of the straight groove, pushing the spring and the return ball 320, causing it to press against the inclined surface of the return surface. The inclined surface decomposes this pressure into a normal force and a tangential force. The tangential force drives the return ball 320 to roll downwards along the inclined surface. The design of the straight groove allows the pressing force to be transmitted directly and without loss to the return ball 320, resulting in high transmission efficiency.

[0045] In one embodiment, exemplarily, such as Figure 1 , Figure 5 As shown, the switch insert 220 is L-shaped, and at least a portion of the switch insert 220 is located on the inner wall of the housing 100, parallel to the guide member 200. A mounting plate 211 is provided on the side of the guide member 200 facing the switch insert 220. The switch contact 210 is spring-loaded onto the mounting plate 211 so that the switch contact 210 can abut against the switch insert 220. The internal space of the turn signal housing 100 is limited, requiring the accommodation of various components such as the guide member 200, the toggle member 300, the reset mechanism, and electrical contacts. The L-shaped switch insert 220 can be bent and fitted onto the side wall or inner wall of the housing 100, transferring the insert that would otherwise occupy space in the central area of ​​the cavity 110 to the edge area of ​​the housing 100. This frees up valuable radial space for the rotation of moving components such as the guide member 200 and the toggle member 300, and for the movement of the reset mechanism, making the overall structure more compact and facilitating miniaturization design.

[0046] Rigid contacts are prone to poor contact due to wear, oxidation, or vibration after prolonged use. In this embodiment, the switch contact 210 is mounted on the mounting plate 211 by a spring, forming an elastic contact system. The spring provides continuous positive pressure to the contact, ensuring that the contact and the insert always maintain tight contact, maintaining low contact resistance even with slight wear or dirt. In addition, the spring can compensate for manufacturing tolerances, assembly errors, and dimensional changes after long-term use, automatically adjusting the contact force. Furthermore, in a vehicle vibration environment, the spring can absorb impact energy, preventing fretting arcs between the contact and the insert, and protecting the contact surface.

[0047] In one embodiment, exemplarily, such as Figure 1 , Figure 2As shown, one end of the toggle member 300 extends from the opening to the outside of the housing 100, and a switch button is provided on the end of the toggle member 300 extending to the outside of the housing 100. The internal guide member 200, reset mechanism, contact insert, etc. are all actuators, while the switch button is the only user interface. The switch button provides the driver with a direct and clear operation point, enabling him to convey driving intentions by tossing or pressing.

[0048] The toggle switch 300 extends from the opening in the housing 100, placing the switch button in an optimal operating area near the steering wheel. The driver can easily toggle or press the button with their thumb or forefinger without taking their hand off the steering wheel, ensuring driving safety.

[0049] The switch button, as an extension of the toggle 300, directly transmits the force applied by the driver to the internal mechanism. Its shape and size can be specially designed to optimize the grip and direction of force application. Of course, a longer toggle 300 can also form an effective lever, reducing the force required for operation and making the action light and effortless.

[0050] This embodiment also provides a vehicle, including a vehicle body and a turn signal switch as described in any of the above embodiments, the turn signal switch being used to control the turn signals of the vehicle body.

[0051] The vehicle in this embodiment includes the turn switch in any of the above embodiments, and thus possesses all the beneficial effects of the turn switch, which will not be elaborated further here.

[0052] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
