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, after long-term use, turn signals are prone to problems such as poor contact at the electrical connection points between the switch contacts and the switch plates, leading to problems such as the turn signals not illuminating or flashing, which affects the driver's normal control of the turn signals. Utility Model Content

[0004] In order to at least address some of the deficiencies mentioned in the related technologies, this application provides a steering switch and a vehicle.

[0005] To achieve the above objectives, this application provides a turn signal switch, including a housing, an actuating element, a switching element, and a resetting element. A cavity is formed within the housing. The actuating element is rotatably mounted on the housing, with one end extending into the cavity. The switching element includes a sliding frame and a bakelite component. The bakelite component is disposed within the cavity, and multiple electrical connection points are arranged on the bakelite component facing the sliding frame. The sliding frame is slidably mounted within the cavity, and a switch contact is arranged on the sliding frame facing the bakelite component. The actuating element can drive the sliding frame to slide, causing the switch contact to engage with the electrical connection points. The resetting element is installed within the cavity, and after the actuating element rotates, it can be reset to its original position.

[0006] Furthermore, multiple electrical connection points are evenly distributed on the bakelite component along the sliding direction of the sliding frame, with gaps between adjacent electrical connection points. The switch contact is located within the gaps and is movable towards the electrical connection points.

[0007] Furthermore, three electrical connection points are provided on the bakelite component, and each switch contact includes two contact positions located in different gaps. The switch contact can simultaneously abut against any two adjacent electrical connection points.

[0008] Furthermore, the actuating element includes a lever and a lever block. The lever is rotatably mounted on the housing, and at least partially extends into the cavity. The lever block is located within the cavity and hinged to the lever, and can rotate synchronously with the lever. A protrusion is provided on the lever block facing the sliding frame, and a corresponding groove is provided on the sliding frame. The protrusion is inserted into the groove and can slide within the groove.

[0009] Furthermore, a support plate is provided on the side of the sliding frame facing the protrusion, and two support plates are symmetrically arranged on the sliding frame, with a groove formed between the two support plates. A sliding groove is opened on the support plate facing the bakelite component, and an extension plate is correspondingly provided on the bakelite component, with the extension plate slidably installed in the sliding groove.

[0010] Furthermore, a support member is provided within the sliding frame, and the switch contact is disposed on the support member and located between the support member and the bakelite component; a straight groove is formed on the support member facing the housing, and a shift bead is installed in the straight groove via a spring. Three shift grooves are formed within the housing, and the three shift grooves are continuously arranged and smoothly transitioned, with the shift bead abutting against the shift groove.

[0011] Furthermore, the reset member is provided with a reset surface, which includes a first inclined surface and a second inclined surface with opposite inclination directions. The lower parts of the first inclined surface and the second inclined surface are connected to form a limiting part. The actuating member is slidably installed in the housing and can move in a direction close to or away from the reset plate. A latch is provided at the end of the actuating member close to the reset plate, and a reset bead is installed in the latch by a spring. The reset bead abuts against the reset surface.

[0012] Furthermore, when the reset bead abuts against the limiting portion, the shift bead abuts against the shift groove located in the middle.

[0013] Furthermore, the lever has a bent portion, and the lever block is installed at the end away from the bent portion. The end of the lever away from the lever block extends to the outside of the housing, and a keycap is installed on the lever.

[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 driver toggles the actuating element, causing it to rotate and slide the sliding frame within the housing. This allows the switch contacts on the sliding frame to contact the electrical connection points on the bakelite component when slid to the appropriate position, thus connecting the circuit corresponding to the electrical connection point and illuminating the turn signal. The driver toggles the actuating element in different directions, causing the sliding frame to slide in different directions, resulting in the switch contacts contacting different electrical connection points, thereby controlling the switching of different turn signals. When it is necessary to turn off the turn signal, the driver uses the reset element to control the actuating element to reset the sliding frame to its original position.

[0016] The turn signal switch of this application controls the sliding frame to move via a toggle mechanism, thus stably controlling the contact and disconnection of the switch contacts with the electrical connection points, thereby controlling the on / off state of the turn signal. The operation is simple. The sliding method of controlling the turn signal circuit is more stable and avoids problems such as poor or unstable contact after prolonged use.

[0024] This embodiment provides a turn signal switch to solve the problem of insensitive contact that may occur in turn signal switches after prolonged use in related technologies.

[0025] Please see Figures 1 to 3This embodiment provides a turn signal switch, including a housing 100, a toggle member 200, a switch member 300, and a reset member 400. A cavity 110 is formed within the housing 100. The toggle member 200 is rotatably mounted on the housing 100, with one end extending into the cavity 110. The switch member 300 includes a sliding frame 320 and a bakelite component 310. The bakelite component 310 is disposed within the cavity 110, and multiple electrical connection points 311 are provided on the bakelite component 310 facing the sliding frame 320. The sliding frame 320 is slidably mounted within the cavity 110, and switch contacts 321 are provided on the sliding frame 320 facing the bakelite component 310. The toggle member 200 can drive the sliding frame 320 to slide, so that the switch contacts 321 contact the electrical connection points 311. The reset member 400 is installed inside the cavity 110. After the toggle member 200 rotates, it can be reset to the position before rotation through the reset member 400.

[0026] Specifically, when the turn signal switch is not activated, the toggle switch 200 is in the neutral position. The sliding frame 320, under the action of the reset member 400, is in its initial position within the cavity 110. The switch contacts 321 on the sliding frame 320 are not in contact with any of the electrical connection points 311 on the bakelite component 310. All turn signal circuits are disconnected, and the lights are off.

[0027] According to the driver's driving intention, the driver moves the actuating element 200 in a certain direction. The actuating element 200 rotates around its axis, and the portion of the actuating element 200 extending into the cavity 110 pushes the sliding frame 320, causing it to slide in a straight line within the cavity 110. The sliding frame 320 moves the switch contact 321 on it together. When the sliding frame 320 slides to a preset position, the switch contact 321 precisely aligns with and contacts the corresponding electrical connection point 311 on the bakelite component 310, the circuit is connected, and current flows through the switch contact 321 and the electrical connection point 311, illuminating the corresponding turn signal. The driver moves the actuating element 200 in different directions, causing the sliding frame 320 to slide in different directions, thereby contacting different electrical connection points 311, achieving independent control of different functions such as left turn signals and right turn signals.

[0028] When the vehicle completes the turn and the steering wheel returns to center, the reset element 400 can be triggered via a linkage mechanism (such as a push rod). The driver can actively move or press the actuating element 200 to reset it. The reset force acts on the actuating element 200 or the sliding frame 320, pushing the sliding frame 320 in the opposite direction, causing it to slide back to its initial position along the original path. After the sliding frame 320 returns to its initial position, the switch contact 321 on it disconnects from all electrical connection points 311, the circuit is broken, and the turn signal is turned off.

[0029] In related technologies, turn signals often employ swing or rotational contact, which can lead to insufficient contact pressure, intermittent connection, or complete failure of the contacts due to vibration and wear. In this embodiment, during the movement of the sliding frame 320, the switch contact 321 and the electrical connection point 311 can be arbitrarily configured as point contact or surface contact according to actual needs. Torque is transmitted through the toggle member 200, ensuring a constant contact pressure between the switch contact 321 and the electrical connection point 311 during contact. Furthermore, the relative sliding friction between the contact and the connection point helps to scrape away the oxide layer or minor dirt on the surface, providing a self-cleaning effect. This double guarantee ensures that the turn signal switch in this embodiment maintains good conductivity even after prolonged use.

[0030] Furthermore, turn switches with swing or rotation structures may wobble due to loose hinges. In this embodiment, the sliding frame 320 slides linearly within the cavity 110, maintaining a stable trajectory without lateral swaying, thus improving structural rationality and overall stability. The sliding friction resistance is low, making operation easy.

[0031] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, multiple electrical connection points 311 are evenly distributed on the bakelite component 310 along the sliding direction of the sliding frame 320, with gaps between adjacent electrical connection points 311. Switch contacts 321 are located within these gaps and can move towards the electrical connection points 311. These multiple electrical connection points 311 typically carry different circuit signals. If there is insufficient insulation distance between these connection points, when the switch contact 321 moves, it may simultaneously contact two or more connection points, leading to a short circuit or crosstalk.

[0032] A physical gap is provided between adjacent electrical connection points 311. The gap acts as an air or solid insulating medium, effectively blocking the current path between different circuits. Even if the switch contact 321 shifts slightly due to manufacturing errors or vibration, as long as its size is smaller than the gap width, it cannot simultaneously connect two connection points. This completely eliminates dangerous malfunctions such as the left and right turn signals illuminating simultaneously due to "gear shifting," improving the safety of this embodiment.

[0033] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, three electrical connection points 311 are provided on the bakelite component 310, and the switch contact 321 includes two contact positions, each located in a different gap. The switch contact 321 can simultaneously abut against any two adjacent electrical connection points 311. This enables dual-position, dual-path control, integrating left and right turn functions. For example, the left electrical connection point 311 corresponds to the left turn signal circuit, the middle electrical connection point 311 corresponds to the common circuit, power supply, or control signal line, and the right electrical connection point 311 corresponds to the right turn signal circuit. When the switch contact 321 simultaneously contacts the left and middle positions, the left turn signal circuit is activated. When the switch contact 321 simultaneously contacts the middle and right positions, the right turn signal circuit is activated. Left and right turn functions can be achieved using only two mechanical positions. Furthermore, the middle electrical connection point 311 serves as a common path shared by both left and right functions, reducing the number of independent circuits and contacts. Each position corresponds to a clear and unambiguous turning intention. Of course, depending on the actual needs of use, the three electrical connection points 311 can also be connected to other circuits, as long as the usage requirements are met.

[0034] If the left and right turn signals used completely independent sets of contacts and wiring, more wiring harnesses, input ports, and software logic would be required. The center electrical connection point 311 can serve as a common terminal. Externally, only the "left / center" and "center / right" signals need to be detected to determine the turn status. Compared to a completely independent dual-circuit design, this reduces the wiring of the common line, lowers hardware costs and software complexity, and improves reliability.

[0035] Because switch contact 321 can only contact "left and center" or "center and right" simultaneously, it is physically impossible for "left" and "right" to contact at the same time. When the sliding frame 320 moves, it must slide from one position to another, passing through a completely disconnected state in between. This fundamentally eliminates the logical error of the left and right turn signals being constantly on simultaneously. It ensures that the signal emitted by the vehicle is always a clear "left turn" or "right turn," without confusing other road users. Even if the driver misoperates, the system will not output a dangerously contradictory signal.

[0036] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, the actuating component 200 includes a lever 210 and a lever block 220. The lever 210 is rotatably mounted on the housing 100, and at least partially extends into the cavity 110. The lever block 220 is located within the cavity 110 and hinged to the lever 210, and can rotate synchronously with the lever 210. A protrusion 221 is provided on the lever 220 facing the sliding frame 320, and a corresponding groove is provided on the sliding frame 320. The protrusion 221 is inserted into the groove and can slide within the groove. The rotation axis of the lever 210 and the linear sliding trajectory of the sliding frame 320 are spatially coaxial. If the lever 210 directly and rigidly pushes the sliding frame 320, the difference in their motion trajectories will cause lateral forces, resulting in jamming, increased wear, or difficulty in operation of the sliding frame 320. The lever block 220 is hinged to the lever 210, forming a universal joint-type flexible connection. When lever 210 rotates, lever 220 can swing freely around the hinge point, automatically adjusting its posture. Lever 220 can adjust its angle in real time to ensure that the protrusion 221 on it is always aligned and smoothly enters the groove of sliding frame 320. This avoids shear force and bending moment generated by rigid connection, protecting the guide rail and contacts of sliding frame 320.

[0037] Furthermore, by providing a lever 220 on the lever 210, the restriction that the lever 210 and the sliding frame 320 must be set adjacent to each other is removed. This allows the positional relationship between the lever 210 and the sliding frame 320 to be flexibly adjusted according to the actual situation during the actual design of this embodiment, making the structure of this embodiment more flexible and improving its applicability.

[0038] The protrusion 221 is inserted into the groove, forming a sliding pair. When the lever 210 rotates, it drives the protrusion 221 through the lever 220. The protrusion 221 slides in the groove, directly pushing the sliding frame 320 to move linearly. As long as the protrusion 221 does not disengage from the groove, the power transmission will not be interrupted. The sidewall of the groove restricts the lateral movement of the protrusion 221, preventing decoupling under vibration or impact and improving the reliability of the transmission.

[0039] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, a support plate 322 is provided on the side of the sliding frame 320 facing the protrusion 221. Two support plates 322 are symmetrically arranged on the sliding frame 320, and a groove is formed between the two support plates 322. A groove 323 is formed on the support plate 322 facing the bakelite component 310, and an extension plate is correspondingly provided on the bakelite component 310. The extension plate is slidably installed in the groove 323. When the sliding frame 320 slides in the cavity 110, if there is a lack of effective guidance, it is easy to deflect, tilt or jam due to lateral force or vibration, resulting in poor contact between the switch contact 321 and the electrical connection point 311, or even accelerated wear. In this embodiment, the groove 323 on the support plate 322 and the extension plate of the bakelite component 310 form a linear guide pair, forcing the sliding frame 320 to slide only along the axial direction of the extension plate. The protrusion 221 of the toggle block 220 slides in the groove formed by the support plate 322, further restricting the degree of freedom of the sliding frame 320 perpendicular to the sliding direction. The dual-guide system ensures that the movement trajectory of the sliding frame 320 is a strictly straight line, without offset or rotation. Even under uneven force, the sliding frame 320 can maintain a parallel posture, protecting the alignment of the contacts and connection points.

[0040] The precise linear motion of the sliding frame 320 directly determines the movement path of the switch contact 321. The electrical connection point 311 is fixed to the bakelite component 310, and the extension plate on the bakelite component 310 serves as the reference for the slide groove 323, maintaining a fixed positional relationship with the electrical connection point 311. Both the slide groove 323 and the electrical connection point 311 use the bakelite component 310 as their mounting reference, eliminating accumulated errors caused by inconsistent references. The sliding frame 320 slides along the extension plate, ensuring that the switch contact 321 on it remains parallel and aligned with the electrical connection point 311, maximizing the contact area and minimizing the resistance.

[0041] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, a support member 324 is provided inside the sliding frame 320. The switch contact 321 is disposed on the support member 324 and located between the support member 324 and the bakelite component 310. A straight groove 325 is formed on the support member 324 facing the housing 100. A shift ball 326 is installed in the straight groove 325 by a spring. Three shift grooves 120 are formed inside the housing 100. The three shift grooves 120 are arranged continuously and smoothly transitioned. The shift ball 326 abuts in the shift groove 120. If the sliding mechanism has no damping or positioning, it lacks operating feel and confirmation, and the driver cannot determine whether it has reached the correct position. The shift ball 326 and the shift grooves 120 constitute a ball positioning mechanism. When the sliding frame 320 moves, the shift ball 326 falls into the three consecutive shift grooves 120 in sequence under the action of the spring. Each time the vehicle enters the bottom of the groove, a noticeable change in resistance occurs, first overcoming the spring force to "climb the slope," and then "falling to the bottom." The driver can clearly feel a "click," corresponding to the engagement of the left or right turn gear. There's no need to look at the instrument panel; the turn signal can be confirmed by feel alone.

[0042] The three shift grooves 120 correspond to the initial position, left-turn position, and right-turn position of the sliding frame 320, respectively. After the shift ball 326 falls into the groove, it is temporarily locked in its current position under spring pressure to resist vibration and minor external forces. Bumps or minor collisions during vehicle operation will not cause the sliding frame 320 to shift unexpectedly, preventing the turn signals from being accidentally turned off or on. It also ensures that the switch contact 321 is always fully aligned and in contact with the corresponding electrical connection point 311, guaranteeing a stable electrical connection.

[0043] In one embodiment, exemplarily, such as Figure 4 , Figure 5 As shown, the reset member 400 is provided with a reset surface, which includes a first inclined surface 410 and a second inclined surface 420 with opposite inclination directions. The lower parts of the first inclined surface 410 and the second inclined surface 420 are connected to form a limiting part 430. The actuating member 200 is slidably installed in the housing 100 and can move in a direction close to or away from the reset plate. A latch 212 is provided at the end of the actuating member 200 close to the reset plate. A reset bead 213 is installed in the latch 212 by a spring and abuts against the reset surface.

[0044] When the driver shifts the lever 200 to the left or right turn position, the reset bead 213 slides upward along the first inclined surface 410 or the second inclined surface 420 of the reset surface, compressing the spring and storing elastic potential energy. When the vehicle steering wheel returns to center, it pushes the lever 200 towards the reset bead 400. Under the action of the spring force, the reset bead 213 quickly slides into the valley limit portion 430 formed by the lower part of the two inclined surfaces, completing the reset. Specifically, when the driver shifts the lever 200 to the left or right turn position, the reset bead 213 slides along the first inclined surface 410 or the second inclined surface 420, increasing the force required to shift gears and improving the driver's adjustment feel.

[0045] When the driver moves the actuating element 200, the reset bead 213 moves from the limiting part 430 to the high position of the slope, overcoming the spring force and generating significant resistance. Upon reaching the high position, the resistance is greatest, forming a "force wall," allowing the driver to perceive that the position is reached. During reset, the reset bead 213 "falls" into the limiting part 430, producing a "click" sensation. Thus, opening has a "climbing" feel, and closing has a "dropping" feel; the force change curve conforms to ergonomics, making operation easy and tactile.

[0046] In one embodiment, exemplarily, such as Figure 4 , Figure 5 As shown, when the reset bead 213 abuts against the limiting part 430, the shift bead 326 abuts against the shift groove 120 located in the middle. The reset bead 213 is the positioning element of the toggle member 200, and its falling into the limiting part 430 indicates that the toggle member 200 has returned to the mechanical initial position. The shift bead 326 is the positioning element of the sliding frame 320, and its falling into the middle shift groove 120 indicates that the sliding frame 320 has returned to the functional initial position. The simultaneous arrival of both in the correct position means that the entire transmission chain is completely reset. This avoids the misalignment state of "the toggle member 200 has returned to the center but the sliding frame 320 has not returned to its position" or "the sliding frame 320 has returned to its position but the toggle member 200 has not returned to the center". Only when both positioning beads are in the middle position is it confirmed that the turn signal circuit is completely disconnected, eliminating the risk of misjudgment or leakage caused by asynchrony.

[0047] In one embodiment, exemplarily, such as Figure 1As shown, the lever 210 has a bent portion 211, and the lever block 220 is installed at the end away from the bent portion 211. The end of the lever 210 away from the lever block 220 extends to the outside of the housing 100, and a keycap is installed on the lever 210. In a vehicle, the core functional components of the turn signal switch must be installed near the steering column tube, but there is a spatial misalignment and obstruction between the driver's finger operation area and the steering column tube. In this embodiment, the bent portion 211 acts as a robotic arm, dividing the lever 210 into two sections. One end is connected to the keycap and is located in a position easily accessible to the driver, while the other end is connected to the lever block 220 through the bent portion 211, extending into the housing 100 to drive the sliding frame 320. The actual position of the keycap can be far away from the core functional area. The keycap can be arranged in the most ergonomic position behind the steering wheel without considering the specific layout of the functional modules below. It easily bypasses components such as the steering column cover and the instrument cluster bracket, avoiding interference. Of course, the same set of internal functional modules can be adapted to the cockpit layout of different car models; simply adjust the bending angle and length of the lever 210.

[0048] This embodiment also provides a vehicle, including a vehicle body and a turn switch according to any of the above embodiments, the turn switch being used to control the turn signals of the vehicle body.

[0049] 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.

[0050] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0051] 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.
