[0019] To better understand and implement this invention, the technical solution will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, an autonomous driving steering wheel that facilitates switching driving modes includes a steering wheel 1, a control panel 3, and a switching component 4. Handles 2 are installed on both sides of the upper end of the steering wheel 1, the control panel 3 is installed in the middle of the steering wheel 1, and the switching component 4 is installed at the lower end of the control panel 3.

[0021] The switching assembly 4 consists of an adjusting seat 401, a connecting sleeve 402, a fixed seat 403, a rotating rod 404, a limiting block 405, a rotating seat 406, a return spring 407, a lifting rod 408, a locking assembly 409, a first sliding groove 410, a connecting groove 411, a limiting groove 412, and an electromagnetic ring 413. The top end of the rotating rod 404 is connected to the middle of the adjusting seat 401, and the upper part of the connecting sleeve 402 is connected to the lower part of the adjusting seat 401 near the outside of the rotating rod 404. The connecting sleeve 402 and the adjusting seat 401 are connected by ball bearings. A fixed seat 403 is connected to the lower part of the connecting sleeve 402 and the rotating rod 404, and locking assemblies 409 are connected to the upper sides of the fixed seat 403. 9; Multiple sets of limiting blocks 405 and rotating seats 406 are installed on the upper part of the rotating rod 404 and the lower part of the connecting sleeve 402. A lifting rod 408 is connected to the upper part of the rotating rod 404. The upper end of the lifting rod 408 and the adjusting seat 401 are connected by bolts. The lower part of the lifting rod 408 is installed in the rotating rod 404 through a bearing sleeved on the outside. A return spring 407 is sleeved on the outside of the lifting rod 408. A first sliding groove 410 is provided inside the adjusting seat 401 and the fixed seat 403. Multiple sets of limiting grooves 412 are provided in the first sliding groove 410. A connecting groove 411 is opened in the middle of the first sliding groove 410. An electromagnetic ring 413 is installed at the lower end of the adjusting seat 401 and the upper end of the fixed seat 403.

[0022] The adjusting seat 401 is slidably connected to the rotating seat 406 at the upper end of the rotating rod 404 through the internal first sliding groove 410, and the adjusting seat 401 is snapped together with the limiting block 405 at the upper part of the rotating rod 404 through the internal limiting groove 412.

[0023] Similarly, the fixed base 403 is slidably connected to the rotating base 406 at the lower end of the connecting sleeve 402 through the internal first sliding groove 410, and the fixed base 403 is snapped together with the internal limiting groove 412 and the limiting block 405 at the lower end of the connecting sleeve 402.

[0024] The locking assembly 409 consists of a tightening member 4091, a clamping rod 4092, a bolt groove 4093, a tightening pin 4094, a fixing sleeve 4095, and a telescopic pin 4096. The clamping rod 4092 is installed on one side of the tightening member 4091, the clamping pin 4094 is installed on the outer side of the clamping rod 4092, the fixing sleeve 4095 is installed on the outer side of the clamping pin 4094, the fixing sleeve 4095 has a bolt groove 4093 near the clamping pin 4094, and the telescopic pin 4096 is installed on one end of the clamping rod 4092.

[0025] The fixing sleeve 4095 is fixed inside the fixing base 403; the clamping rod 4092 and the fixing sleeve 4095 are connected by a sleeve, and the clamping rod 4092 has a return spring on the outside; the tightening pin 4094 and the bolt groove 4093 are connected by a sliding sleeve, and after the tightening part 4091 is tightened, the telescopic pin 4096 and the connecting sleeve 402 are inserted and connected.

[0026] like Figure 1 , 2As shown in Figure 3, the adjusting seat 401 is slidably connected to the rotating seat 406 at the upper end of the rotating rod 404 via the internal first sliding groove 410. The adjusting seat 401 is also snapped together with the limiting block 405 at the upper part of the rotating rod 404 via the internal limiting groove 412. The fixed seat 403 is slidably connected to the rotating seat 406 at the lower end of the connecting sleeve 402 via the internal first sliding groove 410. The fixed seat 403 is also connected to the limiting block at the lower end of the connecting sleeve 402 via the internal limiting groove 412. The 405 snap-fit ​​connection connects the upper end of the lifting rod 408 to the adjusting seat 401 via bolts. The lower part of the lifting rod 408 is embedded in the rotating rod 404 via a bearing sleeved on the outside. The lifting rod 408 and the return spring 407 are sleeved together. The connecting sleeve 402 and the adjusting seat 401 are connected by ball bearings. When switching from unmanned to manual driving, the electromagnetic ring 413 is de-energized, causing the adjusting seat 401 and the fixed seat 403 to disconnect. Then, the handle 2 is pulled. This allows the connecting sleeve 402 to move upwards, with its lower part locked inside the upper part of the fixed seat 403. The locking assembly 409 then secures the lower part of the connecting sleeve 402, allowing the steering wheel 1 to be pulled out of the vehicle body. The rotating rod 404 engages with the lower part of the adjusting seat 401, enabling the rotation of the rotating rod 404 by turning the steering wheel 1. In autonomous driving mode, the locking assembly 409 can be released, and the steering wheel 1 and connecting sleeve 402 can be pressed down into the vehicle body. The adjusting seat 401 and the fixed seat 403 are attracted together by the electromagnetic ring 413, forming a fixed connection. After the adjusting seat 401 is pressed down, it disengages from the upper engagement point of the rotating rod 404. When the rotating rod 404 rotates, it will not drive the steering wheel 1, ensuring the steering wheel 1 remains stable. This completely solves the problem of the steering wheel still rotating in autonomous driving mode, affecting the driver's experience, and the steering wheel becoming uncontrollable and more difficult to control when the autonomous driving mode malfunctions.

[0027] like Figure 2 , 3 As shown in Figure 4, the fixing sleeve 4095 is fixed inside the fixing base 403. The clamping rod 4092 and the fixing sleeve 4095 are sleeved together. A return spring is provided on the outside of the clamping rod 4092. The tightening pin 4094 and the bolt groove 4093 are connected by a sliding sleeve. After the clamping member 4091 is tightened, the telescopic pin 4096 and the connecting sleeve 402 are inserted and connected. In use, the clamping member 4091 is pressed against the fixing sleeve 4095, thereby clamping the clamping rod 4092 and the clamps on both sides of the clamping rod 4092. The tightening pin 4094 moves along the bolt groove 4093, which presses the telescopic pin 4096 into the connecting sleeve 402 to form a limit. Then, by rotating the tightening member 4091, the tightening pin 4094 can be rotated to one side of the bolt groove 4093, so that the tightening pin 4094 remains stable. When releasing, the tightening pin 4094 is rotated back, and the pressing rod 4092 returns to its original position under the action of the external return spring. The telescopic pin 4096 can then retract into the fixed sleeve 4095. The operation is convenient and quick.

[0028] The present invention discloses an autonomous driving steering wheel that facilitates switching driving modes. The working principle is as follows: The electromagnetic ring 413 in the autonomous driving steering wheel is de-energized, disconnecting the adjusting seat 401 and the fixed seat 403. Pulling the handle 2 then moves the connecting sleeve 402 upwards. The lower part of the connecting sleeve 402 is engaged with the upper part inside the fixed seat 403, and then secured by the locking assembly 409. In use, the tightening member 4091 presses against the fixed sleeve 4095, thereby moving the tightening rod 4092 and the tightening pins 4094 on both sides of the tightening rod 4092 along the bolt groove 4093. This presses the telescopic pin 4096 into the connecting sleeve 402, forming a limit. Then, by rotating the tightening member 4091, the tightening pin 4094 is rotated to one side of the bolt groove 4093, causing the tightening pin 4096 to engage. 4. To maintain stability, when released, rotate the tightening pin 4094 back, and the clamping rod 4092 returns to its original position under the action of the external return spring. The telescopic pin 4096 can then retract into the fixing sleeve 4095. The operation is convenient and quick, and the lower part of the connecting sleeve 402 can be fixed, so that the steering wheel 1 can be pulled out of the vehicle body. The rotating rod 404 is engaged with the lower part of the adjusting seat 401. The rotating rod 404 can be controlled by rotating the steering wheel 1. When the vehicle is unmanned, the locking component 409 can be released, and the steering wheel 1 and the connecting sleeve 402 are pressed into the vehicle body. The adjusting seat 401 and the fixing seat 403 are attracted together by the electromagnetic ring 413 to form a fixation. After the adjusting seat 401 is pressed down, it is disengaged from the upper end of the rotating rod 404. When the rotating rod 404 rotates, it will not drive the steering wheel 1, so that the steering wheel 1 can remain stable.
