Therefore, these or other orientation terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third" are only for descriptive purposes and should not be understood as indicating or implying relative importance.

[0082] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two components. For a person skilled in the art, the above belongs to the specific meaning in the present application can be understood according to the specific circumstances.

[0083] In one embodiment of the present application, a storable steering wheel is disclosed, as shown in Figures 1-5 It comprises a steering column 1, a fixed ring segment 2 and a movable ring segment 3, and a folding assembly 4 is connected between the fixed ring segment 2 and the movable ring segment 3 and the steering column 1, and a protruding segment 31 is movably arranged in the movable ring segment 3.

[0084] The steering wheel comprises a storage state and an unfolded state.

[0085] As shown in Figure 1 and Figure 4 When in the storage state, the protruding segment 31 is received into the inside of the movable ring segment 3, and the fixed ring segment 2 and the movable ring segment 3 can be folded towards the steering column 1 through the folding assembly 4.

[0086] As shown in Figure 2 , Figure 3 and Figure 5 When in the unfolded state, the fixed ring segment 2 and the movable ring segment 3 are unfolded to be in the same plane through the folding assembly 4, and the protruding segment 31 is extended to the outside of the movable ring segment 3 and connected to the fixed ring segment 2.

[0087] Further, the movable ring segments 3 are symmetrically arranged at least two with the center of the steering column 1, and the fixed ring segments 2 are symmetrically arranged at least two with the center of the steering column 1. The movable ring segments 3 are arranged at intervals with the fixed ring segments 2.

[0088] The movable ring segments 3 and the fixed ring segments 2 can be folded or unfolded relative to the steering column 1. When folded, the protruding segments 31 in the movable ring segments 3 are retracted into the inside of the movable ring segments 3, thereby reducing the size of the movable ring segments 3. Then, the movable ring segments 3 and the fixed ring segments 2 are folded towards the steering column 1 by the folding assembly 4, so that the overall size of the steering wheel is reduced, thereby facilitating the hiding of the steering wheel. The steering column 1 can be telescopic and rotatable for hiding, thereby further increasing the space of the passenger compartment. When switched to the manual driving mode, the fixed ring segments 2 and the movable ring segments 3 are unfolded to the same plane by the folding assembly 4, and the protruding segments 31 are extended to the outside of the movable ring segments 3. The end of the protruding segment 31 is spliced with the end of the fixed ring segment 2, so that the fixed ring segment 2 and the movable ring segment 3 are connected to form a complete or notched circular, elliptical, square or rectangular steering wheel, thereby facilitating the manual operation of the vehicle by the passenger.

[0089] In some embodiments of the present application, as shown in Figure 6 The movable ring segments 3 are provided with movable cavities 33, which include air inlets 331 and outlets 332. The protruding segments 31 are slidably arranged in the movable cavities 33 and can be extended to the outside of the movable cavities 33 from the outlets 332. The air inlets 331 are connected to the first air inlet assembly 34, which supplies air to the air inlets 331 to push the protruding segments 31 to slide towards the outlets 332.

[0090] Further, as shown in Figure 6 The movable ring segments 3 are provided with two symmetrical protruding segments 31 and movable cavities 33. The first air inlet assembly 34 includes a first air inlet cavity 341 and a first air inlet pipe 342. The first air inlet pipe 342 is connected to an air source, and the first air inlet cavity 341 is formed between the two protruding segments 31 and is connected to the first air inlet pipe 342. The first limiting portion 333 is arranged at one end of the movable cavity 33 close to the first air inlet pipe 342, and the second limiting portion 334 is arranged at one end of the movable cavity 33 close to the outlet 332. The first limiting portion 333 and the second limiting portion 334 can limit the activity range of the protruding segment 31 to avoid the protruding segment 31 from being separated from the movable ring segment 3 or blocking the first air inlet pipe 342.

[0091] In addition, a sealing washer 311 is arranged at the end of the extension section 31 close to the first air inlet pipe 342, which can improve the sealing of the first air inlet cavity 341. When the gas is input into the first air inlet cavity 341 through the first air inlet pipe 342, the extension section 31 is pushed to extend the movable cavity 33 towards the outlet 332 under the action of the gas pressure. When the extension section 31 is retracted into the movable ring section 3, the first air inlet pipe 342 reversely draws the gas to form a negative pressure in the first air inlet cavity 341, so that the extension section 31 can move towards the inside of the movable ring section 3 and be retracted into the inside of the movable ring section 3.

[0092] Furthermore, magnets with opposite magnetic properties are arranged at the ends of the two extension sections 31 close to the first air inlet pipe 342, which can generate a force in the direction of approaching each other between the two extension sections 31, so as to ensure that the extension section 31 will not extend the movable cavity 33 due to the vibration of the vehicle when the extension section 31 is retracted into the movable ring section 3.

[0093] Optionally, a limiting block can be arranged in the movable cavity 33, and a limiting block slot is arranged on the extension section 31. When the extension section 31 is retracted into the movable cavity 33, the limiting block and the limiting block slot are clamped, so as to limit the movement of the extension section 31.

[0094] In some embodiments of the present application, the end of the extension section 31 is provided with a first clamping part 32, the end of the fixed ring section 2 is provided with a second clamping part 20, and the fixed ring section 2 is provided with an unlocking assembly 23 which is linked with the second clamping part 20.

[0095] When in the unfolded state, the first clamping part 32 is clamped with the second clamping part 20.

[0096] When unlocked, the unlocking assembly 23 drives the second clamping part 20 to move, and the first clamping part 32 and the second clamping part 20 are separated.

[0097] The first clamping part 32 is arranged at the end of the extension section 31 away from the first air inlet pipe 342, and the second clamping part 20 is arranged at the end of the fixed ring section 2. When the extension section 31 is extended to be spliced with the end of the fixed ring section 2, the first clamping part 32 is clamped with the second clamping part 20, so as to realize the connection and fixation between the fixed ring section 2 and the movable ring section 3.

[0098] In addition, by arranging the unlocking assembly 23, when the steering wheel is not needed to be used, the unlocking assembly 23 can drive the second clamping part 20 to move, so as to separate the first clamping part 32 and the second clamping part 20. At this time, the extension section 31 can be retracted into the inside of the movable ring section 3, so as to be conveniently stored.

[0099] In some embodiments of the present application, as shown inFigure 7 and Figure 8 As shown in

[0100] As shown in Figure 7 and Figure 9 As shown in

[0101] When locked, the first connecting post 321 moves towards the fixed ring segment 2, the first guide slope 322 contacts the elastic blocking piece 22 and pushes the opening 220 open.

[0102] When the elastic blocking piece 22 moves to the first clamping groove 323, the elastic blocking piece 22 is elastically reset and clamped into the clamping interface 21.

[0103] When unlocked, the unlocking assembly 23 drives the elastic blocking piece 22 to act so that the elastic blocking piece 22 is separated from the first clamping groove 323.

[0104] Further, as shown in Figure 8 The first connecting piece 32 further includes a limiting post 35 and a connecting post 36, the limiting post 35 is fixedly connected to the end of the extending segment 31, and the connecting post 36 is connected between the limiting post 35 and the first connecting post 321, wherein the first clamping groove 323 is formed between the limiting post 35 and the first connecting post 321. The diameter of the limiting post 35 is the same as the diameter of the clamping interface 21.

[0105] Further, as shown in Figure 8 The first connecting post 321 is a conical structure or a similar conical structure, wherein the diameter of the first connecting post 321 gradually decreases away from the extending segment 31, so that the surface of the first connecting post 321 forms the first guide slope 322.

[0106] As shown in Figure 9As shown, the card interface 21 is further provided with a receiving opening 24 for receiving the first connecting post 321, when locked, the first connecting post 321 enters into the card interface 21 and the first guide slope 322 of the first connecting post 321 contacts the elastic blocking piece 22, the elastic blocking piece 22 is deformed under the guidance of the first guide slope 322 and makes the opening 220 expand, when the elastic blocking piece 22 moves to the position of the first clamping groove 323, the elastic blocking piece 22 resets under the elastic action and is clamped into the card interface 21, thereby limiting the axial movement of the first connecting post 321. At the same time, the first connecting post 321 enters into the receiving opening 24 and the limiting post 35 is clamped into the card interface 21, the limiting post 35 can limit the radial movement of the first connecting post 321, and the movable ring segment 3 is flushly connected with the side surface of the fixed ring segment 2, so that the direct connection between the movable ring segment 3 and the fixed ring segment 2 is more stable, firm, smooth and beautiful.

[0108] When locked, the first guide slope 322 contacts the blocking part 221 and pushes the second ends of the two blocking parts 221 to move away from each other, so that the opening 220 is expanded and the elastic part 222 is deformed and stores energy.

[0109] When the blocking part 221 moves to the first clamping groove 323, the elastic part 222 releases energy and drives the blocking part 221 to reset, and the blocking part 221 is clamped into the first clamping groove 323.

[0110] Further, as shown in Figure 9 The blocking part 221 and the elastic part 222 are an integrally formed metal piece, the first ends of the two blocking parts 221 are fixedly connected together and form a V-shaped structure, and the elastic part 222 has a coiled shape. The elastic part 222 can be deformed and generate elastic force, and the elastic part 222 is connected with the fixed ring segment 2 through a connecting pin.

[0111] Further, as shown in Figure 9As shown, at least part of the blocking part 221 is at the end of the accommodating opening 24, and at least part of the blocking part 221 is on the active track of the first docking column 321. When the first docking column 321 is inserted into the accommodating opening 24, the first guide slope 322 on the first docking column 321 can be in contact with the blocking part 221 and push the two blocking parts 221 to move away from each other, so that the opening 220 is enlarged, so that the first docking column 321 can be further inserted into the accommodating opening 24, and the elastic part 222 is elastically deformed and stored. When the first docking column 321 is completely inserted into the accommodating opening 24, the blocking part 221 is relatively moved to the position of the first clamping groove 323, the elastic part 222 is released and drives the blocking part 221 to reset and clamp into the first clamping groove 323, thereby limiting the position of the first docking column 321.

[0112] Optionally, the at least two blocking parts 221 are slidably connected at both ends of the clamping opening 21, and the elastic part 222 is connected between the blocking part 221 and the fixed ring segment 2. When the first docking column 321 is inserted, the two blocking parts 221 can be pushed to slide away from each other, and when the blocking part 221 is relatively slid to the position of the first clamping groove 323, the blocking part 221 is clamped into the first clamping groove 323 under the elastic force of the elastic part 222.

[0115] Further, the unlocking rod 232 is slidably connected with the fixed ring segment 2, and the unlocking rod 232 can slide along the axial direction of the fixed ring segment 2. A limiting hook 234 is arranged at the end of the unlocking rod 232, and the limiting hook 234 can limit the disengagement of the blocking part 221 from the unlocking rod 232.

When locking, the first clamping block 325 is movable to be clamped with the second clamping block 251, so that the fixed ring segment 2 and the movable ring segment 3 are fixedly connected together.

[0123] In some embodiments of the present application, as shown in Figure 11As shown, the unlocking assembly 23 comprises a second movable block 235 and a screw rod 236, the second movable block 235 is in sliding connection with the fixed ring segment 2, the second movable block 235 is connected with the screw rod 236, the adapter 25 is in rotational connection with the fixed ring segment 2, and the adapter 25 is in threaded cooperation with the screw rod 236;

[0124] When unlocking, the second movable block 235 drives the screw rod 236 to move, and the adapter 25 rotates relative to the screw rod 236, and the first clamping block 325 is disengaged from the second clamping block 251.

[0125] Further, the second movable block 235 is slidably arranged in the sliding cavity and can slide when the air source is input into the sliding cavity, thereby driving the second movable block 235 to slide. The adapter 25 is rotatably connected in the fixed ring segment 2, a threaded hole is arranged in the adapter 25, the screw rod 236 is threadedly connected in the threaded hole, and the screw rod 236 is fixedly connected with the second movable block 235, so that the adapter 25 can rotate under the action of the thread when the second movable block 235 slides, thereby changing the angle and position of the second clamping block 251.

[0126] When the fixed ring segment 2 is connected with the movable ring segment 3, the first clamping block 325 and the second clamping block 251 are at the same angle, that is, the first clamping block 325 and the second clamping block 251 are on the same straight line, a guide inclined surface is arranged on the first clamping block 325 or the second clamping block 251, when the first clamping block 325 and the second clamping block 251 are in contact, the plurality of second clamping blocks 251 can be pushed away from each other under the action of the guide inclined surface, when the first clamping block 325 completely passes through the second clamping block 251, the second clamping block 251 is elastically reset, thereby enabling the first clamping block 325 and the second clamping block 251 to be clamped and fixed. When unlocking, the second movable block 235 drives the screw rod 236 to move, the adapter 25 rotates under the threaded driving action of the screw rod 236, so that the first clamping block 325 and the second clamping block 251 are at different angles, that is, the first clamping block 325 and the second clamping block 251 are separated, thereby enabling the fixed ring segment 2 and the movable ring segment 3 to be separated.

[0127] In some embodiments of the present application, as shown in Figure 11 The unlocking assembly 23 further comprises an elastic member 27, the elastic member 27 connects the adapter 25 and the fixed ring segment 2, as shown in Figure 13 The fixed ring segment 2 is provided with a first limiting protrusion 211 and a second limiting protrusion 212;

[0128] When locking, the second clamping block 251 is kept in abutment with the first limiting protrusion 211 under the elastic force of the elastic member 27, and the first clamping block 325 and the second clamping block 251 are in the same straight line direction;

An elastic element 27, which is a torsion spring, is provided between the connector 25 and the fixed ring segment 2. In the initial state, the connector 25, under the action of the torsion spring, keeps the second locking block 251 abutting against the first limiting protrusion 211, at which point the first locking block 325 and the second locking block 251 are at the same angle. When the connector 25 rotates to its limit position, the second locking block 251 abuts against the second limiting protrusion 212 to limit further rotation of the connector 25.

[0131] Optionally, when locked, the second movable block 235 drives the screw rod 236 to move, and the coupling 25 rotates under the action of the screw rod 236 until the second locking block 251 is misaligned with the first locking block 325. When the first locking block 325 moves to one side of the second locking block 251, the second movable block 235 is reset under the action of the return spring 26 and the coupling 25 is reset under the action of the torsion spring, so that the coupling 25 rotates until the first locking block 325 and the second locking block 251 are at the same angle. At this time, the first locking block 325 and the second locking block 251 are locked and fixed.

[0132] Optionally, an installation port is provided in the fixed ring segment 2, the connector 25 is rotatably disposed in the installation port, and the connector 25 can slide along its own axial direction.

The mating joint 25 rotates under the action of the screw rod 236. When the mating joint 25 rotates 90°, the first locking block 325 and the second locking block 251 are misaligned. When the mating joint 25 continues to rotate 90°, the first locking block 325 rotates relative to the second locking block 251 and locks onto the inner side of the second locking block 251. At this time, the first locking block 325 and the second locking block 251 are on the same straight line and are engaged. At this time, the mating joint 25 abuts against the fourth limiting part to restrict the further movement of the mating joint 25.

[0134] When the unlocking is performed, the second movable block 235 drives the screw rod 236 to move towards the docking head 25, the docking head 25 rotates under the action of the screw rod 236, so that the first clamping block 325 and the second clamping block 251 are dislocated and separated, and at this time, the docking head 25 can be separated from the second docking column 324.
