Description

Technical Field

[0001] This application relates to the field of steering wheel technology, specifically to a folding steering wheel, and also to an automobile. Background Technology

[0002] With the rapid development of science and technology, the intelligentization of automobiles has accelerated, making autonomous driving a likely inevitable trend for future intelligent vehicles, bringing them closer to achieving higher levels of intelligent driving scenarios.

[0003] Currently, most smart car steering wheels have a fixed shape design, and during autonomous driving, the steering wheel occupies most of the space in the driver's cabin, preventing the driver from having a more spacious driving environment. Especially in future Level 3 (Level 3) or higher autonomous driving scenarios, the driver may not need the steering wheel, so it will be necessary to fold the steering wheel to provide a more spacious and comfortable environment for the driver.

[0004] Therefore, how to provide a more spacious cabin environment for drivers has become an urgent technical problem to be solved. Utility Model Content

The grip portion is rotatably connected to the steering wheel body. The drive device drives the grip portion to rotate via the transmission device. The drive device and the transmission device are disposed within a receiving cavity on the steering wheel body. The transmission device includes a worm gear, a worm, and a rotating shaft. The worm is connected to the drive device to rotate under the drive of the drive device. The worm gear is engaged with the worm and fixed to the rotating shaft. The rotating shaft is connected to the grip portion. When the worm drives the worm gear to rotate, the worm gear drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the grip portion to rotate relative to the steering wheel body, thereby realizing the folding or unfolding of the grip portion.

[0007] Optionally, the length direction of the pivot is parallel to the crossbeam of the steering wheel body, and the crossbeam is a long strip structure with a preset width.

[0008] Optionally, the steering wheel body includes a support frame disposed within the receiving cavity, and the rotating shaft is disposed on the support frame.

[0009] Optionally, the steering wheel also includes a stop, which is telescopically disposed on the steering wheel body; the stop extends outward when the grip is unfolded to lock and fix it with the pivot, and retracts when the grip is folded to disengage from the pivot and release the lock.

[0010] Optionally, the folding steering wheel further includes a connector, which is fixedly connected to the end of the grip portion, and the second end of the pivot passes through the steering wheel body and is fixed to the connector to achieve the connection between the pivot and the grip portion.

[0014] Optionally, when the gripping part further includes a second gripping part, the transmission device includes two worm gears, the worm simultaneously drives the two worm gears to rotate, and the two worm gears rotate in opposite directions. The two worm gears are respectively distributed on opposite sides of the worm to drive the first gripping part and the second gripping part to rotate respectively.

[0015] This application also provides a vehicle that includes the folding steering wheel described in any of the preceding claims.

[0016] Compared with the prior art, this application has the following advantages:

[0017] This application provides a folding steering wheel, comprising: a steering wheel body, a grip portion, a transmission device, and a drive device. The grip portion is rotatably connected to the steering wheel body. The drive device drives the grip portion to rotate via the transmission device. The drive device and the transmission device are disposed within a receiving cavity on the steering wheel body. The transmission device includes a worm gear, a worm, and a rotating shaft. The worm is connected to the drive device to rotate under the drive of the drive device. The worm gear is engaged with the worm and fixed to the rotating shaft. The rotating shaft is connected to the grip portion. When the worm drives the worm gear to rotate, the worm gear drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the grip portion to rotate relative to the steering wheel body, thereby realizing the folding or unfolding of the grip portion.

[0018] This application provides a folding steering wheel, which includes a steering wheel body, a grip portion, a transmission device, and a drive device. Specifically, the transmission device includes a worm gear, a worm, and a rotating shaft. The worm is connected to the drive device and rotates under the drive of the drive device. The worm gear is connected to the worm and fixed to the rotating shaft. The rotating shaft is connected to the grip portion. One end of the worm is connected to the drive device and rotates under the drive of the drive device. The other end of the worm is connected to the worm gear. When the worm rotates, it can drive the worm gear to rotate. Since the worm is fixed to the rotating shaft, when the worm gear rotates, it can drive the rotating shaft to rotate. The rotating shaft is connected to the grip portion and rotates when the rotating shaft rotates. This can be understood as follows: when the steering wheel needs to be folded, the grip portion can be rotated relative to the steering wheel body through the pivot, so that the grip portion is in a folded state, which can provide the driver with a more spacious cabin environment. Moreover, the folding steering wheel has a simple structure and is easy to install. Attached Figure Description

[0033] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 application. Furthermore, in the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In related technologies, automotive steering wheels and smart car steering wheels mostly adopt a fixed shape design. Furthermore, during autonomous driving in smart cars, the steering wheel occupies a large portion of the driver's cabin space, making it inconvenient for the driver to get in and out, especially for larger drivers. Additionally, in the event of an accident involving a car or smart car, because the steering wheel occupies a significant portion of the driver's cabin space and is located in a central position, it may impound the driver during rescue efforts, greatly hindering the rescue process.

[0036] Accordingly, this application provides a folding steering wheel, comprising: a steering wheel body, a grip portion, a transmission device, and a drive device. The grip portion is rotatably connected to the steering wheel body, and the drive device drives the grip portion to rotate via the transmission device. The drive device and the transmission device are disposed within a receiving cavity on the steering wheel body. The transmission device includes a worm gear, a worm, and a rotating shaft. The worm is connected to the drive device to rotate under the drive of the drive device. The worm gear is engaged with the worm and fixed to the rotating shaft. The rotating shaft is connected to the grip portion. When the worm drives the worm gear to rotate, the worm gear drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the grip portion to rotate relative to the steering wheel body, thereby realizing the folding or unfolding of the grip portion.

[0037] The folding steering wheel provided in this application includes a steering wheel body, a grip portion, a transmission device, and a drive device. Specifically, the transmission device includes a worm gear, a worm, and a rotating shaft. The worm is connected to the drive device and rotates under the drive of the drive device. The worm gear is connected to the worm and fixed to the rotating shaft. The rotating shaft is connected to the grip portion. One end of the worm is connected to the drive device and rotates under the drive of the drive device. The other end of the worm is connected to the worm gear. When the worm rotates, it can drive the worm gear to rotate. Since the worm is fixed to the rotating shaft, when the worm gear rotates, it can drive the rotating shaft to rotate. The rotating shaft is connected to the grip portion and rotates when the rotating shaft rotates. This can be understood as follows: when the steering wheel needs to be folded, the grip portion can be rotated relative to the steering wheel body through the pivot, so that the grip portion is in a folded state, which can provide the driver with a more spacious cabin environment. Moreover, the folding steering wheel has a simple structure and is easy to install.

[0038] The folding steering wheel provided in this application will now be described in detail with reference to the accompanying drawings.

Figure 7 This is a cross-sectional view of another folding steering wheel provided in an embodiment of this application. Figure 8 yes Figure 7 A partial view of another folding steering wheel is shown. Figure 9 yes Figure 1 A partial view of a folding steering wheel is shown. Figure 2 .

[0040] This application provides a folding steering wheel, which includes: a steering wheel body 10, a grip portion 20, a transmission device 30, and a drive device 40. The grip portion 20 is rotatably connected to the steering wheel body 10, and the drive device 40 drives the grip portion 20 to rotate through the transmission device 30. The drive device 40 and the transmission device 30 are disposed in a receiving cavity 101 on the steering wheel body 10.

[0041] like Figures 1-9 As shown, the folding steering wheel includes a steering wheel body 10, a grip portion 20, a transmission device 30, and a drive device 40. The steering wheel body 10 is located at the center of the folding steering wheel and is the main component of the folding steering wheel. The grip portion 20 is rotatably connected to the steering wheel body 10; that is, the rotatable connection can be a hinge connection, a pivot connection, or other types of rotatable connections. In this embodiment, the drive device 40 can control the transmission device 30 to drive the grip portion 20 to rotate, so that the grip portion 20 can switch from a folded state to an unfolded state, or from an unfolded state to a folded state.

[0042] like Figure 1-2 , Figure 4 and Figure 7 As shown, when the grip portion 20 is in the unfolded state, the grip portion 20 and the steering wheel body 10 are on the same horizontal plane, that is, the grip portion 20 and the steering wheel body 10 form a complete steering wheel, which can be a circular structure or a multi-semi-circular structure. The driver can normally operate the steering wheel by gripping the grip portion 20. Figure 3 and Figure 5 As shown, when the grip portion 20 is in the folded state, the grip portion 20 is perpendicular to the steering wheel body 10, that is, the grip portion 20 is located below the steering wheel body 10. It can be understood that folding the grip portion 20 below the steering wheel body 10 reduces the space occupied by the steering wheel in the driver's cabin, providing a more spacious cabin environment for the driver and making it easier for the driver to get in and out of the vehicle.

[0043] The timing of unfolding or folding of the grip portion 20 can be actively set by the driver, or the intelligent vehicle can automatically unfold the grip portion 20 when it needs to be unfolded and automatically fold it when it needs to be folded. In this embodiment, the timing of unfolding or folding of the grip portion 20 will not be described in detail.

[0044] The transmission device 30 and the drive device 40 are disposed within the receiving cavity 101 of the steering wheel body 10. The receiving cavity 101 includes the steering wheel frame and the steering wheel rear cover. The steering wheel frame and the steering wheel rear cover form the receiving cavity 101, which can accommodate the transmission device 30 and the drive device 40. That is, the steering wheel frame and the steering wheel rear cover form a space that can be used to accommodate the transmission device 30 and the drive device 40.

[0045] like Figure 1 and Figure 6-8 As shown, the transmission device 30 includes a worm gear 301, a worm 302, and a rotating shaft 303. The worm 302 is connected to the driving device 40 and rotates under the drive of the driving device 40. The worm gear 301 is connected to the worm 302. The worm gear 301 is fixed to the rotating shaft 303. The rotating shaft 303 is connected to the gripping part 20.

[0046] The drive device 40 can be a motor, and the output shaft of the motor is connected to the worm gear 302. That is, the motor provides a power source for the transmission device 30, and controls the transmission device 30 by driving the motor. Specifically, the motor is located below the worm gear 302. When the motor receives a drive signal, it starts to rotate in response to the drive information, driving the worm gear 302 above it to rotate; that is, the worm gear 302 rotates under the drive of the motor. In this embodiment, the number of drive devices 40 can be set according to specific circumstances; one drive device 40 or two drive devices 40 can be set.

[0047] In other words, one end of the worm gear 302 is connected to the output shaft of the motor, and the worm gear 302 rotates under the drive of the motor. The other end of the worm gear 302 is connected to the worm wheel 301. When the worm gear 302 rotates, it can drive the worm wheel 301 to rotate. Moreover, the worm gear 302 is fixed to the rotating shaft 303. When the worm wheel 301 rotates, it can drive the rotating shaft 303 to rotate. The rotating shaft 303 is connected to the gripping part 20. When the rotating shaft 303 rotates, it can drive the gripping part 20 to rotate.

[0048] In this embodiment of the application, a worm gear 301 is fixed on a rotating shaft 303, that is, the worm gear 301 passes through one end of the rotating shaft 303 and is fixed on the rotating shaft 303, and a worm 302 is provided below the rotating shaft 303, that is, the worm 302 cooperates with the worm gear 301 to rotate.

[0049] The steering wheel body 10 includes a support frame 103, which is disposed within the receiving cavity 101, and the rotating shaft 303 is disposed on the support frame 103. Specifically, as shown... Figure 1 As shown, the steering wheel body 10 also includes a support frame 103, which is disposed in the receiving cavity 101. The support frame 103 is for supporting the rotating shaft 303, that is, the rotating shaft 303 is snapped and fixed on the support frame 103. The support frame 103 can be disposed separately on the frame of the steering wheel or can be integrally formed with the frame of the steering wheel. As long as the support frame 103 is in the receiving cavity 101 and can be used to support the rotating shaft 303, there is no limitation on the specific number of support frames 103 or the specific structure of the support frame 103.

[0050] like Figure 1-3 As shown, the length direction of the pivot 303 is parallel to the crossbeam 102 of the steering wheel body 10, and the crossbeam 102 is a long strip structure with a preset width. Specifically, the crossbeam 102 of the steering wheel is a long strip structure with a preset width, and the crossbeam 102 is located within the space enclosed by the grip portion 20. The length direction of the pivot 303 is parallel to the crossbeam 102 of the steering wheel body, that is, the length direction of the pivot 303 is parallel to the length direction of the long strip structure.

[0051] like Figure 7As shown, the steering wheel also includes a stop 60, which is telescopically mounted on the steering wheel body 10. The stop 60 extends outward when the grip is unfolded to lock and fix it to the pivot 303, and retracts when the grip is folded to disengage from the pivot 303 and release the lock. Specifically, the stop 60 can be a stop pin, located below the pivot 303. When the grip is folded, the stop pin retracts into its retraction cavity, disengaging from the pivot 303, allowing the pivot 303 to rotate. When the grip is unfolded, the stop pin extends outward from its retraction cavity and inserts into the corresponding hole of the upper pivot 303 for locking and fixing, further securing the pivot 303 to prevent its rotation and making the grip more stable in the unfolded state. Of course, the stop 60 can also be a telescopic clamping device, which is provided with a clamping arm that extends to clamp the upper rotating shaft, thereby fixing the stop 60 to the rotating shaft. Of course, other structures for the stop are also possible, which will not be listed here.

[0052] It should be noted that the stop is controlled by an ECU (Electronic Control Unit), that is, the ECU controls the locking or unlocking of the stop and the shaft.

[0053] The transmission device 30 further includes a bearing 304, which is disposed on the support frame 103. The first end of the rotating shaft 303 is rotatably mounted on the support frame 103 via the bearing 304. Figure 1 As shown, when the rotating shaft 303 with the worm gear 301 installed is fixed on the support frame 103, it is necessary to further fix the rotating shaft 303 and the support frame 103. That is, the rotating shaft 303 can be fixed by the bearing 304. The bearing 304 is disposed on the support frame 103 and is used to fix the first end of the rotating shaft 304 on the support frame 103.

[0054] The folding steering wheel also includes a connector, which is fixedly connected to the end of the grip portion 20. The second end of the pivot 303 passes through the steering wheel body 10 and is fixed to the connector to achieve the connection between the pivot 303 and the grip portion 20.

[0055] Specifically, the steering wheel body 10 and the grip portion 20 are connected via the pivot 303. The first end of the pivot 303 is fixed to the support frame 103 via the bearing 304, and the second end of the pivot 303 is connected to the grip portion 20. The connecting member is connected to the end of the grip portion 20; that is, the second end of the pivot 303 passes through the steering wheel body 10 and is fixed to the connecting member, thereby achieving the connection between the pivot 303 and the grip portion 20.

[0056] like Figure 9 As shown, the connector is a block structure 50 with a bend, and the end of the gripping part 20 is provided with an embedding groove 20-a that matches the block structure 50. The block structure 50 is fixedly embedded in the embedding groove 20-a, and the second end of the rotating shaft 303 is fixedly inserted into the block structure 50.

[0057] In this embodiment, the connector is a block structure 50 with angles, and an embedding groove 20-a matching the block structure 50 is provided at the end of the gripping part 20. The block structure 50 can be fixedly embedded in the embedding groove 20-a. An insertion hole is provided at the center of the block structure 50, and the second end of the rotating shaft 303 is inserted into the insertion hole of the block structure 50 to connect the second end of the rotating shaft 303 with the connector, thereby achieving the connection between the rotating shaft 303 and the gripping part 20. The block structure 50 with angles can be square or triangular; its structure is not limited. Alternatively, the second end of the rotating shaft 303 can be directly fixed inside the end of the gripping part 20, i.e., without the need for other connectors.

[0058] It should be noted that the block structure 50 is fixedly embedded in the embedding groove 20-a. The block structure 50 can be fixed in the embedding groove 20-a of the gripping part by interference fit, or by threaded hole fit. There are no restrictions on the method of fixing the connector to the end of the gripping part 20, as long as it meets the requirements.

[0059] like Figure 1-5 As shown, the gripping part 20 includes a first gripping part 201, which is a semi-ring structure. The gripping part also includes a second gripping part 202, which is also a semi-ring structure. When the first gripping part 201 and the second gripping part 202 are unfolded, they form a ring structure.

[0060] In this embodiment of the application, the gripping part 20 has two specific structures, such as... Figure 4As shown, one structure of the gripping part 20 is that the gripping part 20 includes a first gripping part 201, that is, the first gripping part 201 is a semi-circular structure. The semi-circular structure can be a semi-circular structure, or a structure larger than a semi-circular structure, or a structure smaller than a semi-circular structure. The semi-circular structure can be determined according to the actual working conditions.

[0061] The two ends of the first grip portion 201 are respectively connected to the steering wheel body 10. When the first grip portion 201 is in the unfolded state, the first grip portion 201 and the steering wheel body 10 form a semi-circular structure or a semi-elliptical structure, or other structures. Figure 5 As shown, when the first grip portion 201 is in a folded state, the first grip portion 201 is located below the steering wheel body 10. At this time, because the first grip portion 201 is perpendicular to the steering wheel body 10, and only the steering wheel body 10 occupies the effective space of the driver's cabin, the first grip portion 201 is folded below the steering wheel body 10 and does not occupy the effective space of the driver's cabin. This can reduce the space occupied by the steering wheel in the driver's cabin and provide a more spacious cabin environment for the driver.

[0062] like Figure 1-2 As shown, another structure of the grip portion is that it further includes a second grip portion 202. That is, the grip portion 20 is composed of the first grip portion 201 and the second grip portion 202, which are symmetrically arranged and distributed on opposite sides of the steering wheel body 10. The first grip portion 201 and the second grip portion 202 have both an unfolded state parallel to the steering wheel body 10 and a folded state perpendicular to the steering wheel body 10. The structures of the first grip portion 201 and the second grip portion 202 can be the same or different. When the first grip portion 201 and the second grip portion 202 are both in the unfolded state, the first grip portion 201, the second grip portion 202 and the steering wheel body 10 are on the same plane, and the first grip portion 201 and the second grip portion 202 form a ring structure. The ring structure can be an elliptical structure or a circular structure.

[0063] like Figure 3As shown, when the first grip portion 201 and the second grip portion 202 are in a folded state, both the first grip portion 201 and the second grip portion 202 are located below the steering wheel body 10. Since both the first grip portion 201 and the second grip portion 202 are perpendicular to the steering wheel body 10, only the steering wheel body occupies the effective space of the driver's cabin, while the first grip portion 201 and the second grip portion 202 do not occupy the effective space of the driver's cabin. It can be understood that when the first grip portion 201 and the second grip portion 202 are in a folded state, the space occupied by the steering wheel in the driver's cabin can be reduced, providing a more spacious cabin environment for the driver.

[0064] Of course, the above are only two examples of the structure of the grip part 20. It is not excluded that the grip part 20 may have other structures. As long as the grip part 20 is in the folded state and only the steering wheel body 10 occupies the space of the driver's cabin, it conforms to the structure of the grip part described in this application and is within the scope of protection of this application.

[0065] like Figure 1 As shown, when the gripping part 20 further includes a second gripping part 202, the transmission device 30 includes two worm gears 301. The worm 302 simultaneously drives the two worm gears 301 to rotate, and the rotation directions of the two worm gears 301 are opposite. The two worm gears 301 are respectively distributed on opposite sides of the worm 302 to drive the first gripping part 201 and the second gripping part 202 to rotate respectively. Specifically, when the first grip portion 201 and the second grip portion 202 are connected to the steering wheel body 10, two worm gears 301 are provided above one of the worm gears 302, and the two worm gears 301 are respectively distributed on opposite sides of the worm gear 302. That is, one worm gear 302 can drive the two worm gears 301 to rotate simultaneously. Since these two worm gears 301 control different grip portions 20, that is, one worm gear 301 controls the first grip portion 201, and the other worm gear 301 controls the second grip portion 202. When the worm gear 302 drives the two worm gears 301 to rotate simultaneously, the first grip portion 201 and the second grip portion 202 can be unfolded or folded simultaneously.

[0066] It should be noted that when two worm gears 301 are provided above one of the worm gears 302, the worm gear 302 drives the two worm gears 301 to rotate in opposite directions at the same time, so that the two worm gears 301 are transmitted to the corresponding gripping part 20 through their respective rotating shafts 303. This allows the first gripping part 201 and the second gripping part 202 to switch from an unfolded state to a folded state, or from a folded state to an unfolded state at the same time.

[0067] This can be understood as follows: the drive device 40 drives the transmission device as follows: the motor drives the worm gear 302; when the worm gear 302 drives the worm wheel 301 to rotate, the worm wheel 301 drives the rotating shaft 303 to rotate; when the rotating shaft 303 rotates, it drives the grip portion 20 to rotate relative to the steering wheel body 10, thereby folding or unfolding the grip portion 20. In other words, when the steering wheel needs to be folded, the motor drives the worm gear 302 to rotate, the worm gear 302 drives the worm wheel 301 to rotate, the worm wheel 301 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the grip portion 20 to rotate relative to the steering wheel body 10, so that the grip portion 20 is in a folded state, providing the driver with a more spacious cabin environment.

[0068] The folding steering wheel provided in this application has a driving device 40 that drives the worm gear 302 to rotate. When the worm gear 302 rotates, it drives the upper worm wheel 301 to rotate. If there are two worm wheels 301 above the worm gear 302, they will rotate in opposite directions. The worm wheels 301 will then drive the rotating shaft 303, which will further transmit power to the grip portion 20, causing the grip portion 20 to rotate along the direction of the corresponding worm wheel 301. When the steering wheel needs to be folded, the rotating shaft 303 can control the grip portion 20 to rotate relative to the steering wheel body 10, so that the grip portion 20 is in a folded state, providing the driver with a more spacious cabin environment. Moreover, this folding steering wheel has a simple structure and is easy to install.

[0069] This application also provides an automobile comprising the aforementioned folding steering wheel.
