Description

Technical Field

[0002] With the continuous improvement of automobile production technology, automobiles have become an important means of transportation for people's lives and travel. Driving safety has always been a top priority. In addition to using their feet to operate the accelerator, brake and clutch pedals, drivers also need to use their hands to operate the windshield wipers, driving lights and other auxiliary driving operations.

[0003] In autonomous driving assistance applications, if the steering wheel and steering column system need to be folded or retracted, the switch lever on the conventional steering column will interfere with and collide with the dashboard during the retraction process because it cannot rotate.

[0004] Therefore, how to provide a steering column with a rotatable lever is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

The connecting part is connected to the mounting plate by bolts, and the connecting part is provided with a receiving cavity for accommodating the transmission component. The mounting part is used to install the drive component.

[0016] Preferably, the mounting plate has a first U-shaped groove on the side away from the main body, and the connecting part has a second U-shaped groove on the side near the mounting plate. The first groove can mate with the second groove to form a mounting through hole for mounting the rotating shaft.

[0017] Preferably, a rolling bearing is installed in the mounting hole, and the rotating shaft passes through the rolling bearing.

[0018] Preferably, the driving component is a stepper motor.

[0019] Preferably, the transmission gear is welded to the outer circumference of the rotating shaft.

[0021] Preferably, two limiting blocks are provided on the circumferential surface of the transmission gear, which are used to limit the rotation angle of the rotating shaft.

[0022] Compared to the aforementioned background technology, the present invention provides a rotatable lever steering column, comprising: a main body, a rotating shaft, and a driving component; two gear shift blocks are rotatably mounted on the lower side of the main body, and a lever is mounted on each of the opposite sides of the two gear shift blocks; the rotating shaft is installed between the two gear shift blocks, and the gear shift blocks can rotate synchronously with the rotating shaft; the driving component is installed on the lower side of the main body and is connected to the rotating shaft through a transmission assembly, and the driving component is used to drive the rotating shaft to rotate.

[0040] The purpose of this invention is to provide a steering column with a rotatable lever.

[0041] To achieve the above objectives, the present invention provides the following technical solution:

[0042] Please see Figures 1 to 7 This embodiment provides a steering column with a rotatable lever, comprising: a main body 100, a rotating shaft 200, and a driving component 300; two gear shift blocks 110 are rotatably mounted on the lower side of the main body 100, and levers 120 are mounted on opposite sides of the two gear shift blocks 110; the rotating shaft 200 is installed between the two gear shift blocks 110, and the gear shift blocks 110 can rotate synchronously with the rotating shaft 200; the driving component 300 is installed on the lower side of the main body 100, and is connected to the rotating shaft 200 through a transmission assembly 400, and the driving component 300 is used to drive the rotating shaft 200 to rotate.

[0043] Specifically, the steering column includes a main body 100 and two gear shift blocks 110 mounted below the main body 100. Each gear shift block 110 has a lever 120 connected to its outer side. The two gear shift blocks 110 are mounted on the left and right sides below the main body 100, and both can rotate along their axial direction. (See details...) Figure 1 As shown, the direction of the arrow is the direction in which the gear shift block 110 drives the lever 120 to rotate.

[0044] The gear shift levers 110 are used to control auxiliary driving actions such as windshield wipers and headlights. Specifically, the corresponding functions of the gear shift levers 110 can be triggered by moving the lever 120. In this embodiment, a rotating shaft 200 is installed between the two gear shift levers 110. The two ends of the rotating shaft 200 are connected to the gear shift levers 110 respectively. The rotating shaft 200 can rotate synchronously with the gear shift levers 110. In addition, a drive component 300 is installed below the main body 100 as a power source. In this way, when the steering column needs to be retracted and folded, the drive component 300 can drive the rotating shaft 200 to rotate at a certain angle, thereby causing the gear shift levers 110 to rotate synchronously, and thus the lever 120 can also rotate accordingly. By controlling the rotation angle of the drive component 300, the lever 120 can also be adjusted to a suitable angle. In this way, even if the steering column is retracted and folded downwards, the lever 120 will not collide with the instrument panel, thereby ensuring the smooth retraction and folding of the steering column.

[0045] Preferably, the transmission assembly 400 includes a transmission gear 410 and a turbine 420; the transmission gear 410 is fixedly mounted on the outer periphery of the rotating shaft 200; the turbine 420 is mounted on the movable end of the drive member 300, and the turbine 420 meshes with the transmission gear 410.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the transmission component 400 is used to connect the rotating shaft 200 and the driving component 300, that is, to transmit the power of the driving component 300 to the rotating shaft 200. Preferably, in this embodiment, the transmission component is set in the middle position of the rotating shaft 200, that is, the middle position of the two gear moving blocks 110. The driving component 300 is also set in the middle position of the lower side of the main body 100.

[0047] Transmission component 400 is as follows Figure 3 and Figure 4 As shown, the transmission gear 410 is fixedly mounted on the rotating shaft 200, while the turbine 420 is mounted on the movable shaft at the end of the drive member 300, and the mounting position of the drive member 300 is such that the turbine 420 can mesh with the transmission gear 410; this arrangement makes the overall structure of the rotating column more compact and reasonable, and also realizes the rotation of the lever 120.

[0048] It should be noted that the size of the transmission gear 410 can be made according to the actual situation, and since the angle range that the lever 120 can adjust is limited, the transmission gear 410 does not have to be a complete ring gear, and it can retain only the part that needs to mesh.

[0049] Preferably, the main body 100 is provided with a main housing 130 and a drive component mounting shell 140 on its lower side. The main housing 130 is mounted on the lower side of the main body 100, and the drive component mounting shell 140 is detachably mounted on the middle of the lower side of the main housing 130. The rotating shaft 200 is rotatably mounted between the main housing 130 and the drive component mounting shell 140.

[0050] In this embodiment, to facilitate the installation of the rotating shaft and the drive component 300, a main housing 130 and a drive component mounting housing 140 are provided below the main body 100, and the two can be detachably connected by bolts, as detailed below. Figures 5 to 7 As shown, the rotating shaft 200 is rotatably mounted between the two.

[0051] Furthermore, the main housing 130 includes two parallel mounting plates 131, and the drive component mounting housing 140 includes a connecting part 141 and a mounting part 142. The connecting part 141 is connected to the mounting plate 131 by bolts. The connecting part 141 is provided with a receiving cavity 143 for accommodating the transmission assembly 400, and the mounting part 142 is used to mount the drive component 300.

[0052] Specifically, such as Figure 5 As shown, two identical, vertically arranged mounting plates 131 are positioned in the middle of the main housing 130, with parallel dimensions. Bolt holes are provided on their lower surfaces to facilitate the installation of the drive component mounting shell 140. The drive component mounting shell 140 comprises two parts: a connecting part 141 for connecting to the mounting plates 131, and a mounting part 142 located below the connecting part 141 for mounting the drive component 300. Bolt holes are also provided on the top of the connecting part 141 corresponding to the bolt holes on the lower surface of the mounting plates 131 for securing the bolts. The bolt is inserted, and the connecting part 141 has a hollow receiving cavity 143 inside. After the drive component mounting shell 140 and the main shell 130 are connected, the receiving cavity 143 is exactly located between the two gear shift blocks 110. That is to say, the transmission component 400 is exactly located inside the receiving cavity 143. This arrangement can ensure that the transmission component 400 will not be intruded by external impurities and fail, and can ensure the stability of the connection between the transmission components 400. In addition, the transmission component 400 is located in the receiving cavity 143, which also makes it convenient to inject an appropriate amount of grease into it to ensure the smooth operation of the transmission component 400.

[0053] In this embodiment, the mounting part 142 also has a space for engaging the drive component 300. In other words, the shape of the mounting part 142 can be set according to the actual shape and size of the drive component 300, but it is necessary to ensure that the drive component 300 can be stably installed inside the mounting part 142.

[0054] Furthermore, the mounting plate 131 has a first groove 132 in a U-shape on the side away from the main body 100, and the connecting part 141 has a second groove 144 in a U-shape on the side near the mounting plate 131. The first groove 132 can mate with the second groove 144 to form a mounting through hole for mounting the rotating shaft 200.

[0055] To facilitate the installation of the rotating shaft 200, in this embodiment, a first groove 132 with a semi-circular structure is provided on the lower end face of the mounting plate 131, and a second groove 144 is provided on the corresponding connecting part 141. The first groove 132 and the second groove 144 can be joined to form a circular mounting through hole. It should be noted that the diameter of the mounting through hole matches the diameter of the rotating shaft 200, and the mounting through hole is filled with grease to improve the stability of the rotating shaft 200 during rotation.

[0056] Preferably, a rolling bearing is installed in the mounting hole, and the rotating shaft 200 passes through the rolling bearing.

[0057] In this embodiment, a rolling bearing can be installed in the mounting through hole, and the rotating shaft 200 passes through the inner ring of the rolling bearing. This ensures that the rotating shaft 200 rotates more smoothly and effectively avoids noise during rotation.

[0058] Preferably, the drive component 300 is a stepper motor.

[0059] Understandably, in order to accurately control the rotation angle of the rotating shaft 200, that is, to accurately control the rotation angle of the lever 120, the drive unit 300 is preferably a stepper motor. The stepper motor makes it easy for the operator to accurately input the rotation angle of its movable shaft, and the stepper motor can also rotate forward or backward, which can ensure that the lever 120 is reset when the steering column is extended again.

[0060] Preferably, the transmission gear 410 is welded to the outer circumference of the rotating shaft 200.

[0061] Understandably, in order to prevent relative slippage between the transmission gear 410 and the rotating shaft 200, welding can be chosen as the connection method. This connection method has high strength and is simple and convenient to operate.

[0062] Of course, the transmission gear 410 can also be connected in other ways. For example, a flat keyway can be set at the position where the transmission gear 410 needs to be installed on the rotating shaft 200, and a flat key can be set on the inner ring of the transmission gear 410. This can also achieve synchronous rotation of the transmission gear 410 and the rotating shaft 200.

[0063] Preferably, both the main housing 130 and the drive component mounting housing 140 are integrally molded by injection molding.

[0064] Understandably, in order to ensure the overall structural strength of the main housing 130 and the drive component mounting housing 140, both are integral structures and are injection molded.

[0065] Preferably, two limiting blocks are provided on the circumferential surface of the transmission gear 410, which are used to limit the rotation angle of the rotating shaft 200.

[0066] Understandably, in this embodiment, the required rotation angle of the lever 120 is limited and it cannot rotate arbitrarily. Correspondingly, the transmission gear 410 also has a certain rotation range. Therefore, in order to prevent the rotation angle of the turbine 420 and the transmission gear 410 from exceeding the preset range, which would cause the lever 120 to collide with the instrument panel, a limit stop is set at the limit position of the corresponding rotation range on the outer periphery of the transmission gear 410. When the turbine 420 meshes with the transmission gear 410 and rotates to the position of the limit stop, it can no longer rotate.

[0067] Furthermore, a pressure sensor can be installed at the limit stop. The pressure sensor is connected to the drive component 300 through the controller. When the turbine 420 meshes with the transmission gear 410 at the limit stop, the pressure sensor will be triggered. The pressure sensor transmits a signal to the controller, thereby controlling the drive component 300 to stop rotating, thus preventing the transmission component 400 from being damaged.

[0068] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0070] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
