Description

Technical Field

[0001] This utility model relates to the field of automobiles and automobile parts, and in particular to a steering return mechanism and an automobile. Background Technology

[0002] When the driver turns or changes lanes, the turn signal is activated by using the steering wheel. When the vehicle returns to a straight line after turning, the steering wheel is turned a certain distance and returns to center. As the steering wheel returns to center, the turn signal will automatically turn off. The automatic reset of the steering wheel is achieved by the vehicle's return system.

[0003] The turn signal can be turned off in the following ways: when the steering lever is in a fixed steering position, it is done through a mechanical return system; when the steering lever is not in a fixed steering position, that is, when it is an automatic return lever, it is done electronically.

[0004] In current combination switches, the steering lever is operated by rotating the entire lever, which then swings around its base. The return system is also relatively mature. However, triggering steering by moving the entire lever requires a significant travel distance. With the emergence of new interior design styles, traditional steering lever structures are insufficient for short-travel movements, and current mature steering return mechanisms can no longer fulfill this function.

[0044] To enable those skilled in the art to better understand the technical solution of this utility model, the steering return mechanism and automobile of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] The steering return mechanism of this invention is applied to the vehicle cockpit. After the handle is triggered, it can automatically return to its original position as the steering wheel is reset, thus realizing automatic return of the handle after steering is triggered.

[0046] Combination Figure 1 As shown, this utility model provides a steering return mechanism, including a housing 10, a handle assembly 20, a return assembly 30, a return trigger body 40, etc. The housing 10 is fixed on the vehicle cab, and a clearance space is reserved in the housing 10 for the insertion of the steering column of the steering wheel.

[0047] The outer casing 10 is a hollow structure, and other components are installed inside the outer casing 10. An extension 110 is provided on the outer casing 10, and the extension 110 is part of the outer casing 10. The end of the extension 110 extends radially along the steering wheel, giving the outer casing 10 a shape with a radially convex extension. The interior of the extension 110 can accommodate corresponding components, and the connection between the extension 110 and the main body of the outer casing 10 maintains a smooth transition.

[0048] The handle assembly 20 is rotatably mounted on the extension 110 via the first pivot 201, and the handle assembly 20 and the housing 10 are hinged together. The end of the handle assembly 20 can partially extend from the end of the extension 110, and the extended portion of the handle assembly 20 can be operated by the user to rotate the handle assembly 20 around the first pivot 201. Because the handle assembly 20 is mounted on the extension 110, when the function is activated, the user's hand rotates the exposed portion of the handle assembly 20 by a smaller amplitude, achieving short-stroke activation.

[0049] The handle assembly 20 is provided with a toggle block 202, which is located at the inner end of the handle assembly 20. When the handle assembly 20 rotates, the toggle block 202 drives the return assembly 30.

[0050] Combination Figure 5 As shown, the return assembly 30 is installed on the main body of the housing 10 and is not located in the extension 110. The return assembly 30 includes a return rotating body 310, a first steering return block 320, a second steering return block 330, and a torsion spring 340. The return rotating body 310 is used to cooperate with the toggle block 202. The return rotating body 310 is rotatably mounted on the housing 10 around the second rotating shaft 3112. When the handle assembly 20 rotates, the toggle block 202 drives the return rotating body 310 to rotate around the second rotating shaft 3112. The second rotating shaft 3112 can be parallel to the first rotating shaft 201 or have a certain angle with the first rotating shaft 201.

[0051] The first steering return block 320 and the second steering return block 330 are respectively rotatably mounted on the return rotating body 310, and combined with Figure 5 As shown, the first steering return block 320 is rotatably mounted on the return rotating body 310 via the first steering column 321, and the second steering return block 330 is rotatably mounted on the return rotating body 310 via the second steering column 331. The first steering column 321 and the second steering column 331 can be disposed on the return rotating body 310.

[0052] Torsion springs 340 are respectively installed at the pivot points of the first steering return block 320 and the second steering return block 330. Specifically, the torsion springs 340 can be respectively installed on the first steering column 321 and the second steering column 331. The two ends of the torsion spring 340 corresponding to the first steering column 321 abut against the first steering column 321 and the return rotating body 310, respectively, and the two ends of the torsion spring 340 abut against the second steering column 331 and the return rotating body 310, respectively. The torsion springs 340 can give the first steering return block 320 and the second steering return block 330 a rotational tendency in a certain direction, and the torsion springs 340 apply different directions of rotational torque to the first steering return block 320 and the second steering return block 330.

[0053] Combination Figure 5As shown, the torsion spring 340 corresponding to the first steering return block 320 causes the first steering return block 320 to rotate clockwise, and the torsion spring 340 corresponding to the second steering return block 330 causes the second steering return block 330 to rotate counterclockwise. A first stop 322 is provided on the first steering return block 320 to cooperate with the return rotating body 310 to limit the extreme position of the first steering return block 320 rotated by the torsion spring 340; a second stop 332 is provided on the second steering return block 330 to cooperate with the return rotating body 310 to limit the extreme position of the second steering return block 330 rotated by the torsion spring 340.

[0054] Combination Figure 4 As shown, the return rotating body 310 is provided with a toggle groove 3111, and the toggle block 202 is inserted into the toggle groove 3111 to drive the return rotating body 310 to rotate around the second rotating shaft 3112. The toggle groove 3111 is an oblong groove. When the handle assembly 20 is toggleed in different directions, the toggle block 202 moves in different directions to both ends of the oblong groove.

[0055] The return trigger 40 can rotate with the steering wheel, and the return trigger 40 can cooperate with the first steering return block 320 and the second steering return block 330.

[0056] When the handle assembly 20 is rotated, the handle assembly 20 rotates around the first rotating shaft 201, and drives the return assembly 30 to rotate to the trigger position through the cooperation of the toggle block 202 and the toggle groove 3111; when the return trigger body 40 is reset with the rotation of the steering wheel, it can trigger the first steering return block 320 or the second steering return block 330, so that the return assembly 30 and the handle assembly 20 are reset.

[0057] Figure 2B This demonstrates the state where the handle assembly 20 is not moved. Combined with... Figure 2A As shown, the exposed part of the handle assembly 20 is pushed downwards (triggering the left turn signal). The handle assembly 20 rotates counterclockwise around the first pivot 201, and the return rotating body 310 rotates clockwise. After triggering, the handle assembly 20 and the return rotating body 310 remain in the triggered position. At this time, the return rotating body 310 drives the second steering return block 330 into the movement path of the return trigger body 40. When the return trigger body 40 turns left with the steering wheel (rotating counterclockwise), the return trigger body 40 squeezes the second steering return block 330, and the second steering return block 330 compresses the torsion spring 340. At this time, the left turn signal remains in the triggered state. When the return trigger body 40 turns right with the steering wheel (clockwise) to return to the center position, the upper end of the return trigger body 40 pushes the second steering return block 330, thereby causing the return rotating body 310 to return to its original position.

[0058] When the exposed part of the handle assembly 20 is moved upward (triggering the right turn signal), the handle assembly 20 rotates clockwise around the first pivot 201, and the return rotating body 310 rotates counterclockwise. After triggering, the handle assembly 20 and the return rotating body 310 remain in the triggered position. At this time, the return rotating body 310 drives the first steering return block 320 into the movement path of the return trigger body 40. When the return trigger body 40 turns right with the steering wheel (clockwise rotation), the return trigger body 40 squeezes the first steering return block 320, and the first steering return block 320 compresses the torsion spring 340. At this time, the right turn signal remains in the triggered state. When the return trigger body 40 turns left with the steering wheel (counterclockwise) to return to the center direction, the lower end of the return trigger body 40 pushes the first steering return block 320, thereby causing the return rotating body 310 to return to its original position.

[0059] This invention enables the short-stroke handle to automatically return to its original position as the steering wheel resets, meeting the new short-stroke handle reset requirements.

[0060] Based on the above scheme, combined with Figure 3 , Figure 4 As shown, the return rotating body 310 of this utility model includes a return rotating body 311, a return fork 312, and a pressing spring 313. The return rotating body 311 and the return fork 312 are two independent components, which are slidably assembled together, allowing for sliding displacement between them. The return rotating body 311 and the return fork 312 are pressed together by the pressing spring 313, and under the elastic force of the pressing spring 313, the return rotating body 311 and the return fork 312 remain in close contact.

[0061] When forced return occurs, the return rotating body 311 and the return fork 312 slide and misalign with each other to prevent damage. Forced return refers to the process where, when the handle assembly 20 is in the steering position and an external force is applied, the handle assembly 20 remains in that steering position; the return trigger 40 drives the first steering return block 320 or the second steering return block 330 back to the off position. This invention utilizes a separate design for the return rotating body 311 and the return fork 312, coupled with a pressure spring 313. When forced return occurs, the return trigger 40 contacts the first steering return block 320 or the second steering return block 330, thereby causing the return fork 312 to compress the pressure spring 313. The return fork 312 and the return rotating body 311 slide and misalign with each other, preventing damage to any related components. When the forced return is released, under the elastic force of the pressure spring 313, the return rotating body 311 and the return fork 312 return to their original positions.

[0062] Combination Figure 4As shown, the return fork 312 is provided with a sliding hole 3121, which is an oblong hole. The length direction of the sliding hole 3121 is perpendicular to the elastic force direction of the top pressure spring 313. A top pressure notch 3122 is provided in the middle of the side wall of the sliding hole 3121. The wall surface of the top pressure notch 3122 matches the outer surface of the second rotating shaft 3112. The top pressure spring 313 presses the second rotating shaft 3112 against the top pressure notch 3122. Under the push of the elastic force of the top pressure spring 313, the second rotating shaft 3112 can be inserted into the top pressure notch 3122. When there is no forced return, the return rotating body 311 and the return fork 312 move synchronously and both rotate around the second rotating shaft 3112.

[0063] Specifically, the second rotating shaft 3112 is disposed on the return rotating body 311 and is a columnar structure protruding from the upper and lower surfaces of the return rotating body 311. The two ends of the second rotating shaft 3112 are respectively rotated with the outer shell 10.

[0064] Combination Figure 4 As shown, in one specific embodiment, the return fork 312 is provided with two limiting sidewalls 3123, which are disposed on the lower surface of the return fork 312. The return rotating body 311 is provided with a limiting block 3113, which is disposed on the lower surface of the return rotating body 311. The limiting block 3113 is slidably engaged between the two limiting sidewalls 3123, allowing the return fork 312 and the return rotating body 311 to slide relative to each other.

[0065] Combination Figure 4 As shown, the return fork 312 is provided with two limiting plates 3124, which extend laterally and are located at the top of the limiting sidewall 3123. The return rotating body 311 is provided with a support block 3114, which extends laterally and is located on the sidewall of the limiting block 3113. The support block 3114 is used to support the limiting plate 3124 and limit the limiting plate 3124, preventing the return rotating body 311 and the return fork 312 from separating from each other.

[0066] Combination Figure 2B As shown, the return trigger body 40 involved in this utility model is an arc-shaped plate. The distance between the two ends of the arc-shaped plate is greater than the distance between the first steering return block 320 and the second steering return block 330. The first steering return block 320 and the second steering return block 330 are respectively provided with sharp corners that cooperate with the end of the return trigger body 40. The sharp corners form an acute angle. When the return trigger body 40 returns to its original position, the end of the return trigger body 40 can cooperate with the sharp corner of the first steering return block 320 or the second steering return block 330 to abut and contact, apply a thrust, and thus reset the return rotating body 310.

[0067] Based on any of the above technical solutions and their combinations, combined with Figure 1 As shown, a top pin 230 is slidably mounted on the handle assembly 20, and an elastic thrust is applied to the top pin 230 by a top spring 240. The top pin 230 can be translated linearly relative to the handle assembly 20. A curved block 101 is fixedly mounted on the housing 10. Under the elastic push of the top spring 240, the end of the top pin 230 is elastically pressed against the curved block 101. The curved block 101 and the top pin 230 cooperate with each other to limit the handle assembly 20 to the trigger position. That is, when the handle assembly 20 is turned around the first rotating shaft 201 by a certain angle, it will always remain in the trigger position when there is no external force triggering it. For example, when the left turn signal or the right turn signal is turned on, the turn signal will always remain on before resetting.

[0068] Combination Figure 1 As shown, the handle assembly 20 includes a handle 210 and a coupling 220. The coupling 220 is rotatably mounted on the housing 10 via a first rotating shaft 201. The handle 210 and the coupling 220 are connected by a third rotating shaft 203. There is an angle between the first rotating shaft 201 and the third rotating shaft 203, so the entire handle 210 can rotate around two different rotating shafts.

[0069] A portion of the handle 210 is exposed at the end of the extension 110, and the exposed portion of the handle 210 can be operated by the user's hand; the handle 210 and the coupling 220 can rotate synchronously relative to the outer shell 10 around the first rotating shaft 201, and the handle 210 can rotate relative to the coupling 220 around the third rotating shaft 203.

[0070] The actuating block 202 is disposed on the coupling 220. Only when the handle 210 and the coupling 220 rotate synchronously relative to the outer shell 10 around the first rotating shaft 201, the coupling 220 drives the actuating block 202 to rotate, thereby driving the return rotating body 310 to rotate.

[0071] Combination Figure 1 As shown, the outer shell 10 of this utility model includes an upper shell 120 and a lower shell 130. The upper shell 120 and the lower shell 130 are fixedly assembled by snap fasteners to form a cavity. The upper shell 120 and the lower shell 130 each include a portion of an extension 110.

[0072] This utility model also provides an automobile, including the aforementioned steering return mechanism, which can achieve the same technical effect. For other parts of the automobile, please refer to the prior art; this utility model will not elaborate further.

[0073] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
