[0033] A lot of specific details are set forth in the following description to facilitate 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 connotation of this application. Therefore, this application is not limited by the specific implementations disclosed below.

[0034] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this application. In addition, in the description of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0035] In the related art, most of the steering wheels of automobiles and intelligent vehicles adopt a fixed shape design. Moreover, during the process of autonomous driving of intelligent vehicles, the steering wheel occupies most of the space in the driver's cockpit, which will cause inconvenience for the driver to get in and out of the vehicle, especially for drivers with a relatively large build. In addition, in the event of an accident in an automobile or an intelligent vehicle, since the steering wheel occupies a large part of the space in the driver's cockpit and is located at the core of the driver's cockpit, it may get stuck with the driver during the rescue of the driver in the driver's cockpit, bringing great difficulties to the rescue of the driver.

[0036] In view of this, the present application provides a folding steering wheel, comprising: a steering wheel body, a holding portion, a transmission device and a driving device. The holding portion is rotatably connected to the steering wheel body. The driving device drives the holding portion to rotate through the transmission device. The driving device and the transmission device are arranged in 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 driving device to rotate under the drive of the driving device. The worm gear is in mating connection with the worm. The worm gear is fixed to the rotating shaft. The rotating shaft is connected to the holding 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 holding portion to rotate relative to the steering wheel body, so as to realize the folding or unfolding of the holding portion.

[0037] The folding steering wheel provided by the present application includes a steering wheel body, a holding portion, a transmission device and a driving device. Specifically, the transmission device includes a worm gear, a worm and a rotating shaft. The worm is connected to the driving device to rotate under the drive of the driving device. The worm gear is in mating connection with the worm. The worm gear is fixed to the rotating shaft. The rotating shaft is connected to the holding portion. One end of the worm is connected to the driving device. The worm rotates under the drive of the driving device. The other end of the worm is in mating connection with the worm gear. When the worm rotates, the worm can drive the worm gear to rotate. Moreover, the worm is fixed to the rotating shaft. When the worm gear rotates, the worm gear can drive the rotating shaft to rotate. The rotating shaft is connected to the holding portion. When the rotating shaft rotates, the rotating shaft can drive the holding portion to rotate. It can be understood that when it is necessary to fold the steering wheel, the rotating shaft can be used to control the holding portion to rotate relative to the steering wheel body, so that the holding portion is in a folded state, which can provide a more spacious cockpit environment for the driver. Moreover, the folding steering wheel has a simple structure and is convenient for installation.

[0038] Next, the folding steering wheel provided by the present application will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic structural diagram of a folding steering wheel in an unfolded state provided by an embodiment of the present application.

Figure 5 is Figure 4 a schematic structural diagram of another folding steering wheel in the folded state shown in Figure 6 isFigure 1 A partial view of a folding steering wheel as shown Figure 1 . Figure 7 It is a cross-sectional view of another folding steering wheel provided by an embodiment of the present application. Figure 8 It is Figure 7 Another partial view of the folding steering wheel as shown Figure 9 It is Figure 1 A partial view of a folding steering wheel as shown Figure 2 .

[0040] The present application provides a folding steering wheel, which includes: a steering wheel body 10, a holding part 20, a transmission device 30 and a driving device 40. The holding part 20 is rotationally connected to the steering wheel body 10, and the driving device 40 drives the holding part 20 to rotate through the transmission device 30. The driving device 40 and the transmission device 30 are arranged in an accommodation cavity 101 on the steering wheel body 10.

[0041] As Figures 1-9 shown, the folding steering wheel includes a steering wheel body 10, a holding part 20, a transmission device 30 and a driving device 40. The steering wheel body 10 is arranged at the central position of the folding steering wheel and is the main component of the folding steering wheel. The holding part 20 is rotationally connected to the steering wheel body 10, that is, the rotational connection can be a hinge connection or a pivot connection. Of course, it is not excluded that it can also be a rotational connection of other structures. In the embodiment of the present application, the driving device 40 can be used to control the transmission device 30 to drive the holding part 20 to rotate, so that the holding part 20 can be switched from a folded state to an unfolded state, or from the unfolded state to the folded state.

[0042] As Figures 1-2 , Figure 4 and Figure 7 shown, when the holding part 20 is in the unfolded state, the holding part 20 and the steering wheel body 10 are in the same horizontal plane, that is, the holding part 20 and the steering wheel body 10 form a complete steering wheel, and the complete steering wheel can be a circular ring structure or a mostly semi-circular structure. The driver can normally control the steering wheel by holding the holding part 20 tightly. As Figure 3 and Figure 5 shown, when the holding part 20 is in the folded state, the holding part 20 and the steering wheel body 10 are perpendicular to each other, that is, the holding part 20 is located below the steering wheel body 10. It can be understood that the holding part 20 is folded below the steering wheel body 10, thereby reducing the space occupied by the steering wheel in the driver's cockpit and providing a more spacious cockpit environment for the driver to facilitate getting in and out of the vehicle.

[0043] When the holding part 20 is deployed or folded can be actively set by the driver, or the intelligent vehicle can automatically deploy the holding part 20 when it detects the need to deploy it, and can automatically fold it when it needs to be folded. In the embodiments of the present application, no excessive description is made on when the holding part 20 is deployed or folded.

[0044] The transmission device 30 and the driving device 40 are arranged in the accommodation cavity 101 of the steering wheel body 10. The accommodation cavity 101 includes the skeleton of the steering wheel and the rear cover of the steering wheel. The skeleton of the steering wheel and the rear cover of the steering wheel form an accommodation cavity 101 that can accommodate the transmission device 30 and the driving device 40. That is to say, the skeleton of the steering wheel and the rear cover of the steering wheel form a space that can be used to accommodate the transmission device 30 and the driving device 40.

[0045] As Figure 1 and Figures 6-8 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 to rotate under the drive of the driving device 40. The worm gear 301 is connected to the worm 302 in a mating manner. The worm gear 301 is fixed to the rotating shaft 303, and the rotating shaft 303 is connected to the holding part 20.

[0046] The driving device 40 can be a motor, and the output shaft of the motor is connected to the worm 302. That is to say, the motor provides a power source for the transmission device 30, and the transmission device 30 is controlled by driving the motor. Specifically, the motor is arranged below the worm 302. When the motor receives a driving signal, it starts to rotate in response to the driving information. The motor drives the worm 302 above it to rotate, that is, the worm 302 rotates under the drive of the motor. In the embodiments of the present application, the number of the driving devices 40 can be set according to specific situations. One driving device 40 can be set, or two driving devices 40 can be set.

[0047] That is to say, one end of the worm 302 is connected to the output shaft of the motor, and the worm 302 rotates under the drive of the motor. The other end of the worm 302 is connected to the worm gear 301 in a mating manner. When the worm 302 rotates, the worm 302 can drive the worm gear 301 to rotate. Moreover, the worm 302 is fixed to the rotating shaft 303. When the worm gear 301 rotates, the worm gear 301 can drive the rotating shaft 303 to rotate. The rotating shaft 303 is connected to the holding part 20. When the rotating shaft 303 rotates, the rotating shaft 303 can drive the holding part 20 to rotate.

[0048] In an embodiment of the present 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. Moreover, a worm 302 is arranged below the rotating shaft 303, that is, the worm 302 rotates in cooperation with the worm gear 301.

[0049] The steering wheel body 10 includes a support frame 103. The support frame 103 is arranged in the accommodation cavity 101, and the rotating shaft 303 is arranged on the support frame 103. Specifically, as Figure 1 shown, the steering wheel body 10 further includes a support frame 103. The support frame 103 is arranged in the accommodation cavity 101, and the support frame 103 is for supporting the rotating shaft 303, that is, the rotating shaft 303 is clamped and fixed on the support frame 103. The support frame 103 can be separately arranged on the skeleton of the steering wheel or integrally formed with the steering wheel skeleton. As long as the support frame 103 is in the accommodation cavity 101 and can be used to support the rotating shaft 303, the specific number of the support frames 103 and the specific structure of the support frame 103 are not limited.

[0050] As Figures 1-3 shown, the length direction of the rotating shaft 303 is parallel to the cross beam 102 of the steering wheel body 10, and the cross beam 102 is a long strip structure with a preset width. Specifically, the cross beam 102 of the steering wheel is a long strip structure with a preset width. The cross beam 102 is located in the space surrounded by the holding part 20, and the length direction of the rotating shaft 303 is parallel to the cross beam 102 of the steering wheel body. That is to say, the length direction of the rotating shaft 303 is parallel to the length direction of the long strip structure.

[0051] As Figure 7As shown, it further includes a stopper 60 which is telescopically arranged on the steering wheel body 10; the stopper 60 is used to extend outwards to lock and fix with the rotating shaft 303 when the holding part is unfolded, and contract to disengage from the rotating shaft 303 to release the lock when the holding part is folded. Specifically, the stopper 60 can be a stop pin which is arranged below the rotating shaft 303. When the holding part is in the folded state, the stop pin contracts in its contraction cavity, that is, the stop pin disengages from the rotating shaft 303, and the rotating shaft 303 can rotate. When the holding part is in the unfolded state, the stop pin extends outwards, that is, the stop pin extends out from its contraction cavity and inserts into the hole corresponding to the upper rotating shaft 303 for locking and fixing, which can further fix the rotating shaft 303 to prevent the rotation of the rotating shaft 303 and make the holding part more stable when in the unfolded state. Of course, the stopper 60 can also be a telescopic clamping device. The clamping device is provided with clamping arms which extend to clamp the upper rotating shaft to realize the fixation between the stopper 60 and the rotating shaft. Of course, it is not excluded that the stopper can also be other structures, which will not be listed one by one here.

[0052] It should be noted that the stopper is controlled by an ECU (Electronic Control Unit), that is, the ECU controls the locking of the stopper with the rotating shaft or releases the locking of the stopper with the rotating shaft.

[0053] The transmission device 30 further includes a bearing 304 which is arranged on the support frame 103, and the first end of the rotating shaft 303 is rotatably installed on the support frame 103 through the bearing 304. As Figure 1 shown, when the rotating shaft 303 installed with the worm wheel 301 is fixed on the support frame 103, it is necessary to further fix between the rotating shaft 303 and the support frame 103, that is, the rotating shaft 303 can be fixed through the bearing 304. The bearing 304 is arranged 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 further includes a connecting piece which is fixedly connected to the end of the holding part 20, and the second end of the rotating shaft 303 passes through the steering wheel body 10 and is fixed to the connecting piece to realize the connection between the rotating shaft 303 and the holding part 20.

[0055] Specifically, the steering wheel body 10 is connected to the holding part 20 through the rotating shaft 303. The first end of the rotating shaft 303 is fixed on the support frame 103 through the bearing 304, and the second end of the rotating shaft 303 is connected to the holding part 20. The connecting piece is connected to the end of the holding part 20. That is to say, the second end of the rotating shaft 303 passes through the steering wheel body 10 and is fixed to the connecting piece to realize the connection between the rotating shaft 303 and the holding part 20.

[0056] As Figure 9 shown, the connecting piece is a block structure 50 with a fold angle. An embedding groove 20-a matching the block structure 50 is provided at the end of the holding part 20. 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 the embodiment of the present application, the connecting piece is a block structure 50 with a fold angle, and an embedding groove 20-a matching the block structure 50 is provided at the end of the holding part 20. The block structure 50 can be fixedly embedded in the embedding groove 20-a. A insertion hole is provided at the central position 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 so that the second end of the rotating shaft 303 is connected to the connecting piece to realize the connection between the rotating shaft 303 and the holding part 20. The block structure 50 with a fold angle can be a square structure or a triangular structure, and the structure is not limited. Of course, the second end of the rotating shaft 303 can also be directly fixed inside the end of the holding part 20, that is, no other connecting piece is needed.

[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 holding part by interference fit, or the block structure 50 can be fixed in the embedding groove 20-a of the holding part by threaded hole fit. The fixing method of the connecting piece and the inside of the end of the holding part 20 is not limited here, as long as it meets the requirements.

[0059] As Figures 1-5 shown, the holding part 20 includes a first holding part 201, and the first holding part 201 is a semi-circular structure. The holding part further includes a second holding part 202, and the second holding part 202 is a semi-circular structure. The first holding part 201 and the second holding part 202 form an annular structure when unfolded.

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

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

[0062] As Figures 1-2 shown, another structure of the holding portion is that the holding portion further includes a second holding portion 202. That is to say, the holding portion 20 is composed of the first holding portion 201 and the second holding portion 202, and the first holding portion 201 and the second holding portion 202 are symmetrically arranged, and the first holding portion 201 and the second holding portion 202 are respectively distributed on opposite sides of the steering wheel body 10. The first holding portion 201 and the second holding portion 202 have a state of being simultaneously parallel to the steering wheel body 10 in the unfolded state and a state of being simultaneously perpendicular to the steering wheel body 10 in the folded state. The structures of the first holding portion 201 and the second holding portion 202 can be the same or different. When the first holding portion 201 and the second holding portion 202 are simultaneously in the unfolded state, the first holding portion 201, the second holding portion 202 and the steering wheel body 10 are in the same plane, and the first holding portion 201 and the second holding portion 202 enclose an annular structure. The annular structure can be an elliptical structure or a circular structure.

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

[0064] Of course, only two structures of the holding part 20 are listed above, and it does not exclude that the holding part 20 may have other structures. As long as only the steering wheel body 10 occupies the space of the driver's cockpit when the holding part 20 is in the folded state, it conforms to the structure of the holding part described in this application and falls within the scope protected by this application.

[0065] As Figure 1 shown, when the holding part 20 further includes a second holding part 202, the transmission device 30 includes two worm wheels 301. The worm 302 drives the two worm wheels 301 to rotate at the same time, and the rotation directions of the two worm wheels 301 are opposite. The two worm wheels 301 are respectively distributed on opposite sides of the worm 302 to drive the first holding part 201 and the second holding part 202 to rotate respectively. Specifically, when the first holding part 201 and the second holding part 202 are connected to the steering wheel body 10, at this time, two worm wheels 301 are arranged above one worm 302, and the two worm wheels 301 are respectively distributed on opposite sides of the worm 302, that is, one worm 302 can drive the two worm wheels 301 to rotate at the same time. Since these two worm wheels 301 control different holding parts 20, that is to say, one worm wheel 301 controls the first holding part 201, and the other worm wheel 301 controls the second holding part 202. When the worm 302 drives the two worm wheels 301 to rotate at the same time, the first holding part 201 and the second holding part 202 can be unfolded or folded at the same time.

[0066] It should be noted that when two worm wheels 301 are arranged above one worm 302, the worm 302 drives the two worm wheels 301 to rotate in opposite directions at the same time, so that the two worm wheels 301 are transmitted to the corresponding holding parts 20 through their respective rotating shafts 303, and the first holding part 201 and the second holding part 202 can be simultaneously switched from the unfolded state to the folded state, or from the folded state to the unfolded state.

[0067] It can be understood that the process of the driving device 40 driving the transmission device is as follows: when the motor drives the worm 302 and the worm 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 holding part 20 to rotate relative to the steering wheel body 10, so as to realize the folding or unfolding of the holding part 20. That is to say, when it is necessary to fold the steering wheel, the motor drives the worm 302 to rotate, the worm 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 holding part 20 to rotate relative to the steering wheel body 10, so that the holding part 20 is in a folded state, which can provide a more spacious cockpit environment for the driver.

[0068] For the folding steering wheel provided in the present application, when the driving device 40 drives the worm 302 to rotate, the worm 302 will drive the worm wheel 301 above it to rotate. If there are two worm wheels 301 above the worm 302, the two worm wheels 301 will rotate in opposite directions. The worm wheel 301 will then drive the rotating shaft 303, and the rotating shaft 303 will further transmit to the holding part 20, so that the holding part 20 rotates along the direction of the corresponding worm wheel 301. When it is necessary to fold the steering wheel, the rotating shaft 303 can be used to control the holding part 20 to rotate relative to the steering wheel body 10, so that the holding part 20 is in a folded state, which can provide a more spacious cockpit environment for the driver. Moreover, the folding steering wheel has a simple structure and is convenient for installation.

[0069] The present application also provides an automobile, which includes the above-mentioned folding steering wheel. The folding steering wheel includes: a steering wheel body 10, a holding part 20, a transmission device 30 and a driving device 40. The holding part 20 is rotatably connected to the steering wheel body 10. The driving device 40 drives the holding part 20 to rotate through the transmission device 30. The driving device 40 and the transmission device 30 are arranged in the accommodation cavity 101 on the steering wheel body 10. The transmission device 30 includes a worm wheel 301, a worm 302 and a rotating shaft 303. The worm 302 is connected to the driving device 40 to rotate under the drive of the driving device 40. The worm wheel 301 is cooperatively connected with the worm 302. The worm wheel 301 is fixed to the rotating shaft 303, and the rotating shaft 303 is connected to the holding part 20. When the worm 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 holding part 20 to rotate relative to the steering wheel body 10, so as to realize the folding or unfolding of the holding part 20.
