[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] With the improvement of people's living standards and the rapid development of the automotive industry, the number of cars on the road is increasing year by year, and cars are improving people's travel methods and efficiency. However, the problems of congestion and traffic accidents are becoming increasingly serious. Congestion wastes drivers' time, and traffic accidents endanger drivers' lives. To resolve the conflict between time and congestion, and the contradiction between fatigue and traffic accidents, autonomous driving technology has emerged. As the autonomous driving capabilities of cars continue to improve, the proportion of time spent driving manually will decrease, and the usage rate of the steering wheel will gradually decline. However, the traditional steering wheel is fixedly installed in the driver's seat. When not in use, the steering wheel occupies a large space in the driver's seat and cannot be hidden, which affects the smoothness of getting in and out of the car and is also less safe in the event of a collision.

[0039] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The folding steering wheel 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This folding steering wheel 1000 can retract when not in use, saving space in the driver's seat, ensuring smooth entry and exit for the driver, and improving driver comfort; it also ensures safety in the event of a collision. This folding steering wheel 1000 is applied to vehicles, and vehicles equipped with this folding steering wheel 1000 have the same functions as described above, which will not be elaborated further here.

[0040] The vehicle in this embodiment includes a vehicle body and a folding steering wheel 1000, which is disposed on the vehicle body. The folding steering wheel 1000 is connected to the vehicle's steering system via a pivot shaft, thereby controlling the vehicle's driving direction. When the driver or the automatic control system rotates the folding steering wheel 1000, the folding steering wheel 1000 is connected to the steering system via a steering shaft, thereby affecting the rotation direction of the front wheels and controlling the vehicle's driving direction.

[0041] Figure 1 This is a schematic diagram of a folding steering wheel 1000 provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of a folding steering wheel 1000 with the housing 700 removed, provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of a folding steering wheel 1000 with the housing 700, mounting housing 600 and drive member 100 removed, provided in an embodiment of the present invention.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, the folding steering wheel 1000 in this embodiment includes a drive member 100, a steering wheel rim 200, a lead screw 300, a first transmission assembly 400, and a second transmission assembly 500. The lead screw 300 is connected to the steering wheel rim 200, and the steering wheel rim 200 can move along the lead screw 300. The first transmission assembly 400 is connected to the end of the lead screw 300 away from the steering wheel rim 200. The second transmission assembly 500 is connected to the drive member 100, and the second transmission assembly 500 is drively connected to the first transmission assembly 400. The drive member 100 drives the second transmission assembly 500 to rotate, thereby driving the first transmission assembly 400 to rotate, and further driving the steering wheel rim 200 to move relative to the lead screw 300, thus enabling the steering wheel rim 200 to unfold or retract. Through the above structural design, the steering wheel rim 200 can switch between unfolded and retracted states, and the folding steering wheel 1000 has a simple structure, occupies little space, and is flexibly controllable. The driver can control the steering wheel to extend or retract according to actual needs. The steering wheel is extended when in use and retracted when not in use. This saves space in the driver's seat when the steering wheel is not in use, ensuring smooth entry and exit for the driver and improving driver comfort; it also ensures safety in the event of a collision.

[0043] Specifically, please refer to Figure 1 and Figure 2 and combined Figure 3 The steering wheel rim 200 includes a first rim 210 and a second rim 220, and the lead screw 300 includes a first lead screw 310 and a second lead screw 320. There are two first transmission assemblies 400 and two transmission assemblies 500. The first rim 210 is connected to the first lead screw 310 and can move along it; the second rim 220 is connected to the second lead screw 320 and can move along it. One of the first transmission assemblies 400 is connected to the end of the first lead screw 310 away from the first rim 210; the other first transmission assembly 400 is connected to the end of the second lead screw 320 away from the second rim 220. The two second transmission assemblies 500 are arranged in a one-to-one correspondence with the two transmission assemblies, and both second transmission assemblies 500 are connected to the drive member 100. Of course, this allows for independent control of the unfolding or retracting states of the first rim 210 and the second rim 220, making control more flexible and convenient. In this embodiment, the number of driving components 100 can also be two, with each driving component 100 connected to a second transmission component 500 for driving the second transmission component 500 to rotate.

[0044] Please continue reading. Figure 1 and Figure 2 and combined Figure 3Specifically, the structure of the first transmission assembly 400 and the second transmission assembly 500 mentioned above is as follows: In this embodiment, the first transmission assembly 400 includes a first rotating shaft 410 and a worm gear 420. The first rotating shaft 410 is connected to the lead screw 300, and the worm gear 420 is disposed on the first rotating shaft 410. The second transmission assembly 500 is a worm 510, which is connected to the worm gear 420 in a transmission connection, and the end of the worm 510 away from the worm gear 420 is connected to the driving member 100. The first transmission assembly 400 and the second transmission assembly 500 adopt a compact worm gear 510 transmission structure, occupying less space, and can transmit a large amount of power in a small space. In addition, the worm gear 510 transmission has self-locking property, that is, when the worm 510 stops rotating, the worm gear 420 will not rotate in the opposite direction. The worm 510 and the worm gear 420 have a large contact area, and the transmitted contact force is relatively dispersed, which makes the worm gear 510 transmission have a strong load-bearing capacity. In addition, the helical tooth surface of the worm gear 420 has a relatively smooth contact with the tooth surface of the worm gear 420, and the worm gear 420 worm 510 transmission usually has low noise and vibration.

[0045] Of course, the steering wheel rim 200 can also move relative to the lead screw 300 via bevel gear transmission. Specifically, in this embodiment, the first transmission component 400 includes a second rotating shaft and a first bevel gear. The second rotating shaft is connected to the lead screw 300, and the first bevel gear is disposed on the second rotating shaft. The second transmission component 500 includes a third rotating shaft and a second bevel gear. The second bevel gear is disposed on the third rotating shaft and meshes with the first bevel gear. The third rotating shaft is connected to the drive component 100. By using bevel gears, power can be transmitted from one shaft to another shaft perpendicular to it. Bevel gear transmissions typically have high transmission efficiency. Bevel gears have good tooth surface contact, which can effectively reduce friction and transmit more power. Furthermore, the large tooth surface contact area of ​​bevel gears can effectively distribute the load, thereby improving the system's load-bearing capacity. In addition, bevel gears have relatively smooth tooth surface contact, enabling relatively smooth power transmission during transmission and reducing noise and vibration. Bevel gear transmissions can adapt to different load and speed requirements.

[0046] In this embodiment, the steering wheel rim 200 includes a connecting rod 211 and a grip portion 212. The connecting rod 211 is connected to the middle of the grip portion 212, and the end of the connecting rod 211 away from the grip portion 212 is connected to a lead screw 300. The connecting rod 211 is movable along the lead screw 300. The connecting rod 211 has a mounting hole, and the lead screw 300 is fitted into the mounting hole. The connecting rod 211 and the lead screw 300 are movably connected.

[0047] In this embodiment, the drive component 100 is a motor. When the motor rotates forward, the lead screw 300 moves away from the motor to extend the steering wheel rim 200; when the motor rotates in reverse, the lead screw 300 moves towards the motor to retract the steering wheel rim 200. Of course, the drive component 100 can also be a motor, an electromagnetic drive device, or other drive components 100, as long as it can drive the second transmission assembly 500 to rotate, and is not limited here.

[0048] To ensure the aesthetics of the folding steering wheel 1000, please refer to [link / reference needed]. Figure 1 In this embodiment, the folding steering wheel 1000 also includes a housing 700. The housing 700 covers the lead screw 300, the first transmission assembly 400, the second transmission assembly 500, and the drive member 100. When the steering wheel rim 200 is unfolded, the lead screw 300, the first transmission assembly 400, the second transmission assembly 500, and the drive member 100 are all located within the housing 700. By providing the housing 700, all transmission components can be protected and dustproofed, and the housing 700 also makes the folding steering wheel 1000 look more aesthetically pleasing. Specifically, the housing 700 in this embodiment includes a first housing 700 and a second housing 700, which are detachably connected. The first housing 700 and the second housing 700 together enclose an installation space, within which the lead screw 300, the first transmission assembly 400, the second transmission assembly 500, and the drive member 100 are all disposed. The first housing 700 and the second housing 700 can be detachably connected using snap-fit ​​connections or fasteners such as bolts. A detachable connection between the first housing 700 and the second housing 700 facilitates installation and subsequent maintenance. Of course, the first housing 700 and the second housing 700 can also be connected using fixed methods such as welding; this is not limited to these methods.

[0049] Please see Figure 2 To protect the first transmission assembly 400 and the second transmission assembly 500, the folding steering wheel 1000 in this embodiment also includes a mounting shell 600, which covers the first transmission assembly 400 and the second transmission assembly 500. The mounting shell 600 prevents dust and other impurities from entering the first transmission assembly 400 and the second transmission assembly 500, thus preventing them from affecting their normal use and extending their service life.

[0050] The working principle of the folding steering wheel 1000 provided in this embodiment is as follows:

[0051] The driving component 100 drives the second transmission assembly 500 to rotate, which in turn drives the first transmission assembly 400 to rotate, thereby causing the steering wheel rim 200 to move relative to the lead screw 300, thus unfolding or retracting the steering wheel rim 200. In this embodiment, the driving component 100 is a motor. When the motor rotates forward, it drives the second transmission assembly 500 to rotate forward, and the second transmission assembly 500 transmits rotation to the first transmission assembly 400. The first transmission assembly 400 rotates, and it drives the lead screw 300 to move away from the motor, thus unfolding the steering wheel rim 200. When the motor rotates in reverse, it drives the second transmission assembly 500 to rotate in reverse, and the second transmission assembly 500 transmits rotation to the first transmission assembly 400. The first transmission assembly 400 rotates, and it drives the lead screw 300 to move closer to the motor, thus retracting the steering wheel rim 200. This folding steering wheel 1000 has a simple structure, occupies little space, and can be flexibly controlled. The driver can control the unfolding or retraction of the folding steering wheel 1000 according to actual usage needs.

[0052] In summary, the folding steering wheel 1000 includes a drive component 100, a steering wheel rim 200, a lead screw 300, a first transmission assembly 400, and a second transmission assembly 500. The lead screw 300 is connected to the steering wheel rim 200, allowing the steering wheel rim 200 to move along the lead screw 300. The first transmission assembly 400 is connected to the end of the lead screw 300 away from the steering wheel rim 200. The second transmission assembly 500 is connected to the drive component 100 and is also drively connected to the first transmission assembly 400. The drive component 100 drives the second transmission assembly 500 to rotate, which in turn drives the first transmission assembly 400 to rotate, thereby causing the steering wheel rim 200 to move relative to the lead screw 300, thus enabling the steering wheel rim 200 to unfold or retract. This structural design allows the steering wheel rim 200 to switch between unfolded and retracted states. Furthermore, the folding steering wheel 1000 has a simple structure, occupies little space, and offers flexible control. The driver can control the steering wheel to extend or retract according to actual needs. The steering wheel is extended when in use and retracted when not in use. This saves space in the driver's seat when the steering wheel is not in use, ensuring smooth entry and exit for the driver and improving driver comfort; it also ensures safety in the event of a collision.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
