The folding steering wheel assembly 100 of the present embodiment includes: a shaft 120 coupled to the steering shaft 101 in such a manner as to intersect the steering shaft 101; a steering wheel 110 including a coupling portion 112 coupled to the shaft 120 and rotatable about the axial direction of the shaft 120; drive units 150 and 1010 for positioning the steering wheel 110 at the 1 st position where the driver can operate or the 2 nd position where the steering wheel rotates about the shaft 120 at the 1 st position; and a cam part 130 including a fixed cam 431 fixed to the shaft 120 in a circumferential direction and a moving cam 432 coupled to the coupling part 112 and supported by the fixed cam 431, thereby locking the rotation of the steering wheel 110 at the 1 st position.

In addition, according to the present embodiment, there is provided a steering apparatus including the foldable steering wheel assembly 100.

The driving units 150 and 1010 of the foldable steering wheel assembly 100 of the present embodiment rotate the steering wheel 110 with respect to the shaft 120 to position the steering wheel 110 at the 1 st position or the 2 nd position, and apply a torque to the moving cam 432 as shown in fig. 1 to 9 or apply a torque to the coupling unit 112 to rotate the steering wheel 110 as shown in fig. 10 to 13. However, the driving unit shown in the drawings is a preferred embodiment, and the driving unit of the present embodiment is not limited to the embodiment shown in the drawings as long as it can rotate the steering wheel 110.

First, fig. 1 to 3 are referred to.

In the folding type steering wheel assembly 100 of the present embodiment, the steering wheel 110 is not directly coupled to the steering shaft 101, but is coupled to the steering shaft 101 through the shaft 120. That is, the hub 111 of the steering wheel 110 is not directly coupled to the steering shaft 101, but is coupled to the shaft 120 coupled to the steering shaft 101, thereby being connected to the steering shaft 101.

The shaft 120 is coupled to the steering shaft 101 in such a manner as to intersect the steering shaft 101. That is, the axial direction of the shaft 120 is perpendicular to the axial direction of the steering shaft 101. The shaft 120 provides the steering wheel 110 with a rotation axis in a direction perpendicular to the axial direction of the steering shaft 101.

The steering wheel 110 includes a coupling portion 112 coupled to the shaft 120, and the steering wheel 110 rotates about the shaft 120 by sliding between the shaft 120 and the coupling portion 112.

As shown in the drawing, the coupling portion 112 is formed to protrude forward from the hub of the steering wheel 110. The coupling portion 112 protruding forward is coupled to the shaft 120, and the steering wheel 110 rotates about the axis of the shaft 120.

The coupling portion 112 is formed with an insertion hole 421 into which the shaft 120 is inserted. That is, when the shaft 120 is inserted into the insertion hole 421, the coupling portion 112 is coupled to the shaft 120, and the steering wheel 110 rotates about the axis of the shaft 120 by sliding between the inner circumferential surface of the coupling portion 112 and the outer circumferential surface of the shaft 120.

As shown in the drawing, the steering wheel 110 is provided with a pair of coupling portions 112, and each coupling portion 112 is coupled to the shaft 120 by forming an insertion hole 421.

The pair of coupling portions 112 are coupled to both ends of the shaft 120, respectively, and the steering shaft 101 is coupled to a central portion of the shaft 120. That is, the pair of coupling portions 112 are positioned on both sides with respect to the axial direction of the steering shaft 101 along the axial direction of the shaft 120. As will be described later, one coupling portion 112 of the pair of coupling portions 112 is supported by the support portion 211, the moving cam 432 is coupled to the other coupling portion 112, and the coupling portion 112 is pressed in the axial direction of the shaft 120 by the cam portion 130, whereby the rotation of the steering wheel 110 is locked.

The steering wheel 110 is rotated about the axis of the shaft 120 by the driving unit 150, moved from the 1 st position to the 2 nd position or moved from the 2 nd position to the 1 st position, is positioned at the 1 st position in the driver running mode, is rotated about the axis of the steering shaft 101 by the driver's operation, and is positioned at the 2 nd position and is accommodated in the vehicle body when the autonomous running mode is switched. A hinge bracket 140 for providing a driving portion 150, etc. are coupled to the shaft 120, and this will be described in detail later.

As shown in fig. 1 and 2, the 1 st position of the steering wheel 110 is a position where the steering wheel 110 and the steering shaft 101 are arranged on the same shaft, and thus can rotate about the shaft of the steering shaft 101, and as shown in fig. 3, the 2 nd position of the steering wheel 110 is a position where the steering wheel 110 rotates about the shaft of the shaft 120 at the 1 st position. The figure shows an embodiment in which the 2 nd position of the steering wheel 110 is directed to the lower side, but the 2 nd position of the steering wheel 110 may be directed to the upper side.

The steering wheel 110 at the 2 nd position can be housed inside the vehicle body. For example, the steering wheel can be housed inside the dashboard of the vehicle by a shortening (telescope) action of the steering shaft 101. Thus, for example, in the autonomous travel mode, a wider driver seat space is ensured, the steering wheel is prevented from interfering with the body, and the driver can perform a driving operation freely and comfortably. In addition, during autonomous driving, steering is performed by the system without the driver's steering wheel operation, and the steering wheel is accommodated in the vehicle body, so that it is possible to fundamentally prevent the driver from performing intervention steering such as grasping the steering wheel or performing interference during driving operation.

The cam portion 130 includes a fixed cam 431 and a moving cam 432. The fixed cam 431 is fixedly coupled to the shaft 120 in the circumferential direction and is not rotated when the steering wheel 110 is rotated, and the moving cam 432 is coupled to the coupling portion 112 and is rotated together when the steering wheel 110 is rotated. Cam surfaces supporting each other are formed on the fixed cam 431 and the moving cam 432, respectively, so that when the steering wheel 110 is rotated, the fixed cam 431 and the moving cam 432 are moved away from or close to each other, whereby the rotation of the steering wheel 110 is locked or unlocked.

Therefore, when the steering wheel 110 is located at the 1 st position by the driving part 150, the rotation is locked by the cam part 130, so that the steering wheel 110 is prevented from being rotated by the driver or an external force, thereby enabling safe steering in the driver's driving mode.

According to one embodiment, the rotation of the steering wheel 110 is locked in the 1 st position and unlocked in the 2 nd position. That is, when the steering wheel 110 is located at the 1 st position, the moving cam 432 and the fixed cam 431 are moved away from each other, and the coupling portion 112 is pressed in a direction toward the support portion 211, so that the rotation of the steering wheel 110 is locked, and when the steering wheel 110 is located at the 2 nd position, the moving cam 432 and the fixed cam 431 are moved closer, the pressing force applied to the coupling portion 112 is released, and the rotation of the steering wheel 110 is unlocked.

According to another embodiment, the rotation of the steering wheel 110 may be locked not only in the 1 st position but also in the 2 nd position. That is, in the 1 st position and the 2 nd position, the engaging portion 112 is pressed by the cam portion 130, the rotation of the steering wheel 110 is locked, and the rotation of the steering wheel 110 is unlocked by releasing the pressing force applied to the engaging portion 112 by the cam portion 130 while the steering wheel 110 is moving from the 1 st position to the 2 nd position or from the 2 nd position to the 1 st position.

Referring to fig. 4 to 5, the shaft 120 is formed with a support portion 211, the support portion 211 supports one coupling portion 112 of the pair of coupling portions 112 in the axial direction of the shaft 120, and the moving cam 432 is fixed to the other coupling portion of the pair of coupling portions 112. As shown in the drawing, the coupling portion 112 and the moving cam 432 are coupled by being pressed into grooves and projections formed in the coupling portion.

The support portion 211 is formed with a diameter larger than a portion where the coupling portion 112 is coupled to one end of the shaft 120, thereby supporting the coupling portion 112 in the axial direction. A shaft, for example, a needle thrust shaft is provided between coupling portion 112 and support portion 211, and rotation of coupling portion 112 is supported thereby.

The other end of the shaft 120 is coupled to the remaining one of the coupling portions 112, and a step 411 for supporting the coupling portion 112 in the axial direction is formed at the other end of the shaft 120. Further, chamfered portions are formed at the other end of the shaft 120 and the fixed cam 431, respectively, and the chamfered portions are supported by each other, so that the shaft 120 and the fixed cam 431 are fixed in the circumferential direction.

The moving cam 432 is positioned between the coupling portion 112 and the fixed cam 431, supported by the fixed cam 431 and the cam surface, and includes a spring 440 for pressing the fixed cam 431 toward the moving cam 432, and a nut 450 coupled to the shaft 120 and supporting the spring 440.

On the other hand, the fixed cam 431 is further formed with a hinge 435 that is hinge-coupled to a nut 153 described later, which will be described later in detail.

Next, referring to fig. 6 to 7, a 1 st blocker 433 is formed at the fixed cam 431, a 2 nd blocker 434 is formed at the moving cam 432, and the 1 st blocker 433 and the 2 nd blocker 434 are supported by each other at the 1 st position and the 2 nd position of the steering wheel 110 to limit the rotation range of the steering wheel 110.

The drawing illustrates an embodiment in which a pair of 1 st stoppers 433 spaced apart from each other in a circumferential direction are formed at the fixed cam 431, and a 2 nd stopper 434 of the moving cam 432 moves between the 1 st stoppers 433 such that the 1 st stopper 433 and the 2 nd stopper 434 are supported at the 1 st position or the 2 nd position of the steering wheel 110. The arrangement and shape of the 1 st blocker 433 and the 2 nd blocker 434 are not limited to the illustrated embodiment, and various configurations may be provided.

The rotation range of the steering wheel 110 is limited by the 1 st blocker 433 and the 2 nd blocker 434, so that the steering wheel 110 is accurately located at the 1 st position or the 2 nd position when the steering wheel 110 is rotated by the driving part 150.

Next, the driving unit 150 for rotating the steering wheel 110 will be described.

The steering wheel 110 is rotated. The driving unit 150 includes a bolt 152 and a nut 153 and transmits power to the moving cam 432.

Fig. 1 to 9 illustrate an embodiment in which the driving portion 150 including the bolt 152 and the nut 153 applies a torque to the moving cam 432 to rotate the steering wheel 110.

Specifically, referring to fig. 1 and 8 to 9, the driving part 150 includes a nut 153 hinge-coupled to the moving cam 432, and an actuator 151 hinge-coupled to the hinge bracket 140 fixed to the shaft 120 and rotating a bolt 152 coupled to the nut 153.

The moving cam 432 is formed with a hinge 435 to be hinge-coupled to the nut 153. The nut 153 may be directly hinge-coupled with the hinge part 435, but as shown in the drawings, is preferably hinge-coupled with the hinge part 435 through an additional bracket.

One end of the hinge bracket 140 is coupled to the shaft 120, and the actuator 151 is hinge-coupled to the other end of the hinge bracket 140. The actuator 151 includes a motor, a decelerator, and a housing coupled with the motor and receiving the decelerator, the housing being hinge-coupled to the hinge bracket 140.

Bolt 152 is connected to a motor through a reducer, and is rotated by the driving of the motor, and bolt 152 is coupled with nut 153 so that nut 153 slides along the axis of bolt 152 when bolt 152 is rotated.

Therefore, when the actuator 151 is driven by sliding the bolt 152 of the nut 153, hinge-coupling the hinge bracket 140 of the actuator 151, and hinge-coupling the moving cam 432 of the nut 153, a torque is applied to the moving cam 432, and the steering wheel 110 is rotated.

Next, the embodiments shown in fig. 10 to 13 will be explained. However, for convenience of explanation, the same reference numerals are used for the common components with the embodiments shown in fig. 1 to 9, and detailed explanation is omitted, and the differences will be mainly explained.

Referring to fig. 10, in the foldable steering wheel assembly 100 of the present embodiment, as in the above-described embodiment, the coupling portion 112 of the steering wheel 110 is coupled to the shaft 120 to rotate, and the cam portion 130 for locking and unlocking the rotation of the steering wheel 110 is coupled to the shaft 120.

The driving unit 1010 includes a gear 1013 and applies torque to the coupling unit 112 to rotate the steering wheel 110. Specifically, gear teeth are formed on the coupling portion 112, and the driving portion 1010 includes a gear 1013 engaged with the gear teeth of the coupling portion 112 and an actuator 1011 for rotating the gear 1013 to apply a torque to the coupling portion 112.

As shown, the gear teeth of the coupling portion 112 are formed on the outer side surface of the coupling portion 112.

The actuator 1011 includes a motor, a speed reducer, and a housing that houses the speed reducer and is coupled to the shaft 120 via a bracket.

The actuator 1011 and the gear 1013 are connected by a cable 1012, which is in the form of a twisted wire having flexibility and capable of transmitting torque.

One end of the cable 1012 is coupled to the gear 1013, and the other end is connected to a decelerator inside the housing of the actuator 1011. Referring to fig. 10 to 11, a support bracket 1020 supporting an end coupled to the gear 1013 of the cable 1012 is coupled to the shaft 120.

The support bracket 1020 rotatably supports a holder 1101 that houses one end of the cable 1012. The holder 1101 is formed in a hollow cylindrical shape, and internally houses an end portion of the cable 1012, and the holder 1101 is supported by the support bracket 1020 via a bearing. Therefore, the power of the actuator 1011 is transmitted to the gear 1013 through the cable 1012 via the support bracket 1020 and the holder 1101.

Referring to fig. 12 to 13, the moving cam 432 and the fixed cam 431 include a 1 st stopper 433 and a 2 nd stopper 434 for limiting a rotation range of the steering wheel 110. Unlike the above-described embodiment, the hinge portion is not formed in the moving cam 432. The gear 1013 is coupled to the gear of the coupling part 112, so that the torque of the driving part 1010 is transmitted to the steering wheel 110 to rotate the steering wheel 110, and when the steering wheel 110 is located at the 1 st position or the 2 nd position, the 1 st blocker 433 and the 2 nd blocker 434 are supported by each other to limit the rotation range of the steering wheel 110.

According to the foldable steering wheel assembly having such a shape and the steering apparatus including the foldable steering wheel assembly, the steering wheel can be housed in the vehicle body, and particularly in the autonomous traveling mode, the space for the driver's seat is secured, the steering wheel is prevented from interfering with the body, the driver's comfortable driving operation is realized, and the driver is prevented from being involved in steering.

The above description is merely illustrative of the technical idea of the present disclosure, and various modifications and variations can be made by those skilled in the art without departing from the essential characteristics of the technical idea. In addition, the present embodiment does not limit the technical idea of the present disclosure, but explains the present disclosure, and thus the scope of the technical idea is not limited to such an embodiment. The scope of the present disclosure should be construed in accordance with the following claims, and all technical ideas within the same scope should be included in the scope of the present disclosure.
