In the related art, the locking mechanism locks the steering column by the mutual cooperation of the handle and the cam pressing plate assembly, and the steering column can be locked or unlocked when the cam pressing plate of the cam pressing plate assembly and the cam connected with the handle generate relative motion. However, the operation force applied to the handle is large, which may affect the user experience, for example, for some female drivers, the difficulty of operating the handle is high, and the steering column is easy to loosen automatically due to insufficient locking force when the handle is adjusted. In addition, when the cam pressing block and the cam run relatively, sudden change of force can be generated, and the sudden change can lead a driver to use larger force to control the handle in the manual locking process, so that the operation difficulty of adjusting the steering column is improved, and the use experience of a user is influenced.

In view of this, the inventor of the present disclosure has abandoned the technical solution of manually controlling the locking mechanism, and instead controlled the action of the locking mechanism in an electric manner in the present disclosure to lock or release the steering column. Specifically, the present disclosure provides a steering column assembly, which at least comprises a steering column, a mounting bracket, a motor, a transmission component and a pressing block. The mounting bracket is used for mounting the motor and the pressing block and is used for being fastened and connected with the body of the vehicle. The motor is connected with the pressing block in a transmission mode through the transmission assembly, the pressing block can be driven to move along the direction towards the steering column through the transmission assembly during forward rotation (reverse rotation) of the motor, so that the pressing block is abutted against the steering column, and the steering column is locked through the pressing block. When will adjusting steering column, the motor reversal (corotation), the motor no longer makes the briquetting move along the direction towards steering column through drive assembly to the briquetting is no longer with the steering column butt, in order to loosen steering column, consequently, realize steering column's automatic locking or unclamp through the motor, the operation degree of difficulty when can reduce steering column and adjust, in addition, can improve the effort between briquetting and the steering column, thereby can improve the locking effect when steering column is in the locking.

The following describes the steering column assembly, the steering system and the vehicle provided by the present invention in detail with reference to specific embodiments.

Fig. 1 is a perspective view of a steering column assembly according to the present embodiment, fig. 2 is a first exploded view of the steering column assembly according to the present embodiment, and fig. 3 is a second exploded view of the steering column assembly according to the present embodiment.

Referring to fig. 1, the present embodiment provides a steering column assembly 100, the steering column assembly 100 at least includes a mounting bracket 110, a steering column 120, and a locking mechanism 130. The mounting bracket 110 includes a first main body 111, a first connecting portion 112, and a second connecting portion 113, the first main body 111 is used for fastening and connecting to a vehicle body of a vehicle, and a connecting end of the first connecting portion 112 and a connecting end of the second connecting portion 113 are respectively fastened and connected to two opposite ends of the first main body 111.

The steering column 120 is disposed between the first connection portion 112 and the second connection portion 113, and the locking mechanism 130 is used to lock the steering column 120 and includes a motor 131, a transmission assembly 132, and a pressing block 133. The pressing block 133 is movably mounted on the first connecting portion 112 and is in transmission connection with the output shaft of the motor 131 through the transmission assembly 132. The motor 131 is installed on the mounting bracket 110, and the motor 131 is used for driving the pressing block 133 to lock or unlock the steering column 120.

The first body portion 111 may have a rod-shaped structure or a plate-shaped structure, and is not particularly limited thereto. Each of the first connection portion 112 and the second connection portion 113 may have a polygonal plate-shaped structure, and is not particularly limited herein. Both the first connection portion 112 and the second connection portion 113 may be fastened and connected to the first body portion 111 by welding, screwing, or the like, but of course, the first body portion 111, the first connection portion 112, and the second connection portion 113 may be integrated to improve the connection strength between the first body portion 111 and the first connection portion 112 and the second connection portion 113.

It should be noted that the first connecting portion 112 and the second connecting portion 113 may be oppositely disposed along a direction perpendicular to the axial direction of the steering column 120, so as to balance the force applied to the mounting bracket 110.

The motor 131 may be mounted on the first body portion 111 or the first connection portion 112, and is not particularly limited herein, and in addition, the motor 131 may be electrically connected to a controller of the vehicle, so that the motor 131 may be controlled to rotate in the forward or reverse direction to lock or unlock the steering column 120. The motor 131 may be fastened to the first body portion 111 or the first connecting portion 112 by a screw connection, a snap connection, or the like, and is not particularly limited herein.

Since the pressing piece 133 is drivingly connected to the output shaft of the motor 131 through the transmission assembly 132, and thus the steering column 120 is configured with the locked state and the unlocked state, how the motor 131 controls the steering column 120 to switch between the locked state and the unlocked state will be described below. When the motor 131 rotates forward (reversely), the motor 131 drives the pressing block 133 to move in a direction towards the steering column 120 through the transmission assembly 132, and the distance between the pressing block 133 and the steering column 120 gradually decreases until the pressing block 133 abuts against the steering column 120, in other words, the motor 131 applies a force to the pressing block 133 through the transmission assembly 132 to enable the pressing block 133 to abut against the steering column 120, so that the pressing block 133 locks the steering column 120. When the motor 131 rotates reversely (rotates normally), the motor 131 no longer applies a force to the pressing piece 133 through the transmission assembly 132 to abut the pressing piece 133 against the steering column 120, in other words, the positive pressure between the pressing piece 133 and the steering column 120 disappears, so that the pressing piece 133 no longer locks the steering column 120 to release the steering column 120.

It should be noted that, when the pressing block 133 is no longer abutted to the steering column 120, in order to reduce the difficulty of adjusting the steering column 120, the locking mechanism 130 may further include a return spring, one end of the return spring may be fastened to or abutted to the pressing block 133, the other end of the return spring may be fastened to or abutted to the mounting bracket 110 or the steering column 120, and the return spring is compressed when the pressing block 133 is abutted to the steering column 120, so that when the pressing block 133 is no longer abutted to the steering column 120, the return spring makes the pressing block 133 move in a direction away from the steering column 120, so that the pressing block 133 is no longer in contact with the steering column 120, which is helpful to further reduce the resistance when the steering column 120 is adjusted.

To translate the rotation of the motor 131 into a motion in a direction perpendicular to the axial direction of the steering column 120, as shown in fig. 2 and 3, the transmission assembly 132 may include a mounting rod 1321 and a transmission piece 1322 in some possible implementations. The first connection portion 112 is located between the driving member 1322 and the steering column 120, can secure a space required for movement of the driving assembly 132, and can be connected to the motor 131. The transmission member 1322 is movably connected to the first connecting portion 112 through the mounting rod 1321, a first end of the transmission member 1322 is configured to abut against the pressing block 133, a second end of the transmission member 1322 is configured to be in transmission connection with an output shaft of the motor 131, and the motor 131 is configured to drive the transmission member 1322 to move along an axial direction of the mounting rod 1321, so that the pressing block 133 can lock or unlock the steering column 120. With the transmission assembly 132 having such a structure, the rotation of the motor 131 can be converted into an urging force for abutting the pressing block 133 against the steering column 120, and automatic locking or unlocking can be achieved.

It is understood that the axial direction of the mounting rod 1321 may intersect with the axial direction of the steering column 120, and in addition, the first and second connecting

portions

112 and 113 may be oppositely disposed along the length direction of the mounting rod 1321.

The first connecting portion 112 may be fastened to the mounting rod 1321 by clipping, screwing, etc., and is not limited herein.

The transmission element 1322 may be slidably or threadably connected to the mounting rod 1321, so that the transmission element 1322 may move in the axial direction of the mounting rod 1321, and the transmission element 1322 may abut against the pressure piece 133.

When the transmission member 1322 is slidably connected to the mounting rod 1321, the motor 131 may be in threaded engagement with the transmission member 1322 via a screw, the motor 131 drives the screw to rotate, and the transmission member 1322 is disposed on the screw and in threaded engagement with the screw, so that the transmission member 1322 can move along the axial direction of the mounting rod 1321.

When the motor 131 is in threaded connection with the mounting rod 1321, the motor 131 drives the transmission piece 1322 to rotate, and due to the fact that the transmission piece 1322 is in threaded connection with the mounting rod 1321, the transmission piece 1322 can move along the axial direction of the mounting rod 1321 to be close to or far away from the pressing block 133, so that the pressing block 133 can be pushed to move along the direction towards the steering column 120, and the pressing block 133 can be abutted against the steering column 120.

It will be appreciated that when the transmission member 1322 is threadably coupled to the mounting rod 1321, the transmission member 1322 is mounted on the mounting rod 1321, and further, the transmission member 1322 is movably coupled to the output shaft of the motor 131 in the axial direction of the mounting rod 1321, so as to ensure that the transmission member 1322 can move relative to the motor 131 in the axial direction of the mounting rod 1321.

When the transmission piece 1322 is screwed to the mounting rod 1321, in order to enable the motor 131 to drive the transmission piece 1322 to rotate, the output shaft of the motor 131 may be engaged with the transmission piece 1322 in the circumferential direction, so as to drive the transmission piece 1322 to rotate. For example, in some examples, a first slot is provided on an end surface of a free end of the output shaft of the motor 131, and the second end of the transmission piece 1322 is inserted into the first slot, so that the output shaft of the motor 131 is engaged with the transmission piece 1322 in the circumferential direction. In other examples, a second slot is disposed at an end of the transmission member 1322 close to the motor 131, and the output shaft of the motor 131 is inserted into the second slot and is engaged with the transmission member 1322 in the circumferential direction. In still other examples, the transmission assembly 132 may further include: one end of the clamping sleeve is fixedly connected with the output shaft of the motor 131, the other end of the clamping sleeve is sleeved on the transmission piece 1322 and is clamped or in threaded connection with the transmission piece 1322, and the transmission piece 1322 is clamped with the clamping sleeve in the circumferential direction so as to ensure that the transmission piece 1322 can move along the axial direction of the mounting rod 1321.

In some examples, to reduce the cost of manufacturing the drive member 1322, the drive member 1322 may be a nut that is externally threaded onto the mounting stem 1321 such that the drive member 1322 threadably engages the mounting stem 1321.

In some possible implementations, the pressing block 133 may be movably disposed on the mounting rod 1321 and located between the first connecting portion 112 and the driving member 1322, and the first connecting portion 112 is located between the steering column 120 and the driving member 1322, so as to simplify the structure of the locking mechanism 130, which helps to improve the compactness of the locking mechanism 130.

It will be appreciated that the pressing block 133 is provided with a through hole for the mounting rod 1321 to pass through and the through hole is in clearance fit with the mounting rod 1321, so that the pressing block 133 can move.

It should be noted that the return spring in the above description may also be sleeved on the mounting rod 1321 and abutted against or tightly connected with the pressing block 133.

In some possible implementations, in order to mount the pressing piece 133 on the mounting rod 1321 and cooperate with the steering column 120, the pressing piece 133 may include a second main body portion 1331 of a plate-shaped structure and a cantilever portion 1332 provided on a side wall of the second main body portion 1331, the second main body portion 1331 is sleeved on the mounting rod 1321 and is used for abutting against the transmission piece 1322, and a free end of the cantilever portion 1332 is used for abutting against the steering column 120.

The cantilever portion 1332 may directly abut against the steering column 120, or, referring to fig. 3, the locking mechanism 130 may further include an elastic member 134, a connection end of the elastic member 134 is tightly connected to the cantilever portion 1332, a free end of the elastic member 134 abuts against the steering column 120, the elastic member 134 is compressed in the process of compressing the steering column 120, and after the steering column 120 is released, the elastic member 134 may drive the pressing block 133 to be away from the steering column 120. In addition, the free end of the resilient member 134 can engage with the steering column 120 when abutting against the steering column 120, which helps to improve the locking effect.

In some possible implementations, referring to fig. 2, a first opening is provided on the first connecting portion 112, and the first opening is used for passing through an end of the pressing block 133 abutting against the steering column 120, so that the pressing block 133 can be matched with the steering column 120.

It should be noted that the first opening may be configured to allow the cantilever portion 1332 or the elastic member 134 (as shown in fig. 3) to pass through, and the first opening may allow the cantilever portion 1332 or the elastic member 134 to abut against the steering column 120.

In some possible implementations, the first connecting portion 112 and the second connecting portion 113 are both plate-shaped structures, the first main body portion 111 includes two first plate-shaped portions and two second plate-shaped portions that are arranged at intervals along the axial direction of the steering column 120, opposite ends of the first connecting portion 112 are respectively fastened to a first end of the first plate-shaped portion and a first end of the second plate-shaped portion, opposite ends of the second connecting portion 113 are respectively fastened to a second end of the first plate-shaped portion and a second end of the second plate-shaped portion, and the first plate-shaped portion and the second plate-shaped portion are used for being fastened to a vehicle body of a vehicle.

In some possible implementations, as shown with reference to fig. 1-3, the steering column assembly 100 may further include: a housing 140. Wherein, the housing 140 has a cavity for accommodating the steering column 120 and is located between the first connecting portion 112 and the second connecting portion 113, the housing 140 is provided with a second opening for allowing one end of the pressing block 133 abutting against the steering column 120 to pass through, and the housing 140 is tightly connected with the mounting bracket 110 through the mounting rod 1321, so that the steering column 120 can be located between the first connecting portion 112 and the second connecting portion 113.

It will be appreciated that the end of the pressing piece 133 passing through the second opening may be the cantilever portion 1332, or the second opening may be used for passing the elastic member 134, and in addition, the steering column 120 is in clearance fit with the cavity, so that the position of the steering column 120 can be adjusted.

Under the action of the motor 131 and the transmission assembly 132, the pressing block 133 moves along the axial direction of the mounting rod 1321, so that the distance between the pressing block 133 and the steering column 120 becomes gradually smaller, and then the pressing block 133 pushes the steering column 120 to move along the axial direction of the mounting rod 1321 until the steering column 120 abuts against the inner wall of the cavity, so that the steering column 120 is locked.

In some examples, as shown in fig. 2 and 3, the housing 140 may include a third body portion 141, a first lug portion 142, and a second lug portion 143.
