For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection, it can be a direct connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are contradictory.

[0038] With the improvement of vehicle automation, more wiring harnesses will be arranged in the steering column assembly of the vehicle. However, the length of these wiring harnesses is fixed. In order to avoid failures during steering wheel position adjustment due to too short wiring harness length, the length of these wiring harnesses is relatively long to ensure that there is enough margin to adapt to the position adjustment of the steering wheel.

[0039] However, when the steering wheel is in certain positions (such as away from the driver, that is, closer to the front cabin), the wiring harness becomes too loose, which greatly increases the risk of interference between the wiring harness and surrounding parts.

[0040] In response to the above problems, the present application provides a steering system. Figure 1 This is a partial schematic diagram of a steering system provided according to one embodiment of the present application. Figure 1 The steering system includes a steering column assembly 100 and a steering wheel 200. The steering wheel 200 is connected to one end of the steering column assembly 100.

[0041] Specifically, the steering wheel 200 is connected to one end of the steering column assembly 100 to transmit steering input. It should be noted that the steering column assembly 100 generally has the freedom of movement to extend and retract along its axial direction, so that the driver can manually pull the steering wheel 200 to adjust the position.

[0042] Figure 2 for Figure 1 Schematic diagram of the steering column assembly 100. Figure 2 Furthermore, the steering column assembly 100 includes a steering column 110, a telescopic harness device 130, and a locking adjustment structure 140. The locking adjustment structure 140 is clamped on the steering column 110 and is used to lock or release the steering column 110, and the telescopic harness device 130 is connected to the locking adjustment structure 140.

[0043] When the locking adjustment structure 140 releases the steering column 110, the harness 133 in the telescopic harness device 130 can be telescopically adjusted in length. When the locking adjustment structure 140 locks the steering column 110, the harness 133 in the telescopic harness device 130 is locked.

[0044] In a specific application, the steering column 110 includes a column tube assembly and a steering shaft assembly, etc. The column tube assembly includes an upper column tube and a lower column tube, etc. The steering shaft assembly includes an upper steering shaft and a lower steering shaft, etc. The end of the steering wheel 200 connected to the steering column 110 generally refers to the end of the upper steering shaft in the steering column 110 close to the driver, and the telescopic freedom of the steering column assembly 100 mainly refers to the relative movement of the column tube assembly and the steering shaft assembly in their axial directions.

[0045] The locking adjustment structure 140 is fixedly mounted on the outer peripheral wall of the steering column 110 to achieve the purpose of clamping the steering column 110 . The locking adjustment structure 140 can lock or release the steering column 110 and is mainly used to switch the state of the steering column 110 .

[0046] Specifically, when the locking adjustment structure 140 is in the state of releasing the steering column 110, it indicates that the steering column 110 is in the released state, and the steering column 110 can perform telescopic movement in its axial direction. Correspondingly, the telescopic harness device 130 is also in the released state, and the harness 133 in the telescopic harness device 130 can adjust the length by telescopic adjustment to adapt to the change in the length of the steering column 110 caused by telescopic movement.

[0047] When the locking adjustment structure 140 locks the steering column 110, it indicates that the steering column 110 is in a locked state, and the steering column 110 cannot perform telescopic movement, that is, the length cannot be adjusted. Correspondingly, the telescopic harness device 130 is also in a locked state, and the length of the harness in the telescopic harness device 130 cannot be changed.

[0048] In this way, the locking adjustment structure 140 can realize that the steering column 110 and the telescopic harness device 130 are simultaneously in a released state or a locked state.

[0049] In a specific application, when the position of the steering wheel 200 needs to be adjusted, the steering column 110 and the telescopic wiring harness device 130 are switched to a released state through the locking adjustment structure 140. At this time, the position of the steering wheel 200 can be adjusted, and the length of the wiring harness in the telescopic wiring harness device 130 can be adaptively adjusted according to the length change of the steering column 110.

[0050] When the position of the steering wheel 200 is appropriate, the steering column 110 and the telescopic harness device 130 are switched to a locked state through the locking adjustment structure 140 to complete the adjustment of the position of the steering wheel 200. It should be understood that the length of the harness in the telescopic harness device 130 is adapted to the length of the steering column 110.

[0051] It can be seen that in the steering column assembly 100, a telescopic wiring harness device 130 is additionally provided, and cooperates with the locking adjustment structure 140 to achieve that during the process of adjusting the position of the steering wheel 200, the wiring harness 133 in the telescopic wiring harness device 130 can adaptively adjust the length to adapt to the length change of the steering column 110, avoid interference with surrounding parts due to the excessive length of the wiring harness 133, and reduce the risk of vehicle failure.

[0052] Figure 3 for Figure 2 An exploded view of the steering column assembly 100. Figure 3 In a further optional embodiment, the locking adjustment structure 140 includes a bracket clamping mechanism 141, a handle 142 and a connecting assembly 143.

[0053] The bracket clamping mechanism 141 is mounted on the steering column 110, and the connecting assembly 143 is connected to the bracket clamping mechanism 141, the handle 142 and the telescopic harness device 130, and the handle 142 and the telescopic harness device 130 are arranged on opposite sides of the bracket clamping mechanism 141. The handle 142 cooperates with the connecting assembly 143 to switch the bracket clamping mechanism 141 to lock or release the steering column 110.

[0054] It should be noted that the locking and adjusting structure 140 locking or releasing the steering column 110 refers to the bracket clamping mechanism 141 locking or releasing the steering column 110. It should be noted that the bracket clamping mechanism 141 is widely used in the steering column assembly 100 of the vehicle, and the bracket clamping mechanism 141 includes a second elastic member 1411 and a plurality of bent plates, etc., and the bent plates can be elastically deformed. It should be understood by those skilled in the art that the bent plates can be clamped on the steering column 110 under the action of the second elastic member 1411.

[0055] In this embodiment, the handle 142 and the telescopic harness device 130 are fixed by the connection assembly 143 in cooperation with the bracket clamping mechanism 141 , and the telescopic harness device 130 and the handle 142 are respectively located on opposite sides of the bracket clamping mechanism 141 .

[0056] The handle 142 cooperates with the connecting assembly 143 to adjust the clamping tightness of the bracket clamping mechanism 141, thereby changing the matching clearance between the column tube assemblies in the steering column 110 to lock or release the steering column 110.

[0057] Furthermore, when the adjustment handle 142 is loosened, the bracket clamping mechanism 141 releases the steering column 110 and also puts the telescopic harness device 130 in a loose state. When the adjustment handle 142 is locked, the bracket clamping mechanism 141 locks the steering column 110 and also puts the telescopic harness device 130 in a locked state.

[0058] In a further optional embodiment, the connecting assembly 143 includes a fixed shaft 1431 and a screw-connector 1432 , and the fixed shaft 1431 passes through the handle 142 , the bracket clamping mechanism 141 , and the telescopic harness device 130 in sequence.

[0059] One end of the fixed shaft 1431 cooperates with the bracket clamping mechanism 141 to set the handle 142 on one side of the bracket clamping mechanism 141, and the other end of the fixed shaft 1431 cooperates with the bracket clamping mechanism 141 and the screw connector 1432 to set the telescopic wire harness device 130 on the other side of the bracket clamping mechanism 141.

[0060] In this embodiment, the connecting assembly 143 is mainly composed of a fixed shaft 1431 and a screw-connector 1432 , and the fixed shaft 1431 passes through the handle 142 , the bracket clamping mechanism 141 and the telescopic harness device 130 in sequence.

[0061] One end of the fixed shaft 1431 abuts the handle 142 against one side of the bracket clamping mechanism 141, and the other end of the fixed shaft 1431 cooperates with the screw connector 1432 to abut the telescopic wiring harness device 130 against the other side of the bracket clamping mechanism 141, thereby fixing the handle 142 and the telescopic wiring harness device 130 on opposite sides of the bracket clamping mechanism 141.

[0062] It should be noted that, when the adjustment handle 142 is loosened, the fixed shaft 1431 can slightly move along its axial direction, thereby changing the tightness of the bracket clamping mechanism 141 and switching the state of the telescopic harness device 130 .

[0063] exist Figure 3 In the illustrated embodiment, the screw connector 1432 is a nut, one end of the fixed shaft 1431 is provided with an external thread, gaskets 1401 are arranged on both sides of the bracket clamping mechanism 141, and a gasket 1401 is also provided on one side of the telescopic wiring harness device 130. The handle 142 and the telescopic wiring harness device 130 are installed by cooperating with the screw connector 1432 and the gasket 1401 through the fixed shaft 1431.

[0064] Of course, the threaded connector 1432 is not limited to a nut. For example, the threaded connector 1432 may also be a screw. Accordingly, one end of the fixed shaft 1431 is provided with a threaded hole to match the threaded connector 1432 .

[0065] Figure 4a for Figure 2 Schematic diagram of the telescopic harness device 130. Figure 4b for Figure 4a sectional view of the telescopic harness device 130. Figure 4a as well as Figure 4b The telescopic wire harness device 130 includes a housing 131 , a winding core 132 , a wire harness 133 and a first elastic member 134 .

[0066] The winding core 132 is disposed in the housing 131 . The wire harness 133 is wound around the winding core 132 and has two ends extending out of the housing 131 . The first elastic member 134 is disposed in the housing 131 and connected to the winding core 132 .

[0067] The fixed shaft 1431 passes through the shell 131 and the winding core 132 and extends out of the shell 131 . The winding core 132 can rotate relative to the fixed shaft 1431 and can move axially with the fixed shaft 1431 to abut against or be disconnected from the inner wall of the shell 131 .

[0068] In this embodiment, the telescopic wire harness device 130 is mainly composed of a shell 131, a winding core 132, a wire harness 133 and a first elastic member 134, wherein the winding core 132 and the first elastic member 134 are both installed in the shell 131, and the shell cavity in the shell 131 is large enough to ensure that the winding core 132 can rotate, and the wire harness 133 is wound around the winding core 132.

[0069] Furthermore, the fixed shaft 1431 passes through the housing 131 and the winding core 132 , and the winding core 132 can rotate relative to the fixed shaft 1431 , that is, the fixed shaft 1431 is located at the position of the rotation axis of the winding core 132 .

[0070] As can be seen from the foregoing, during the process of adjusting the handle 142 to loosen or tighten, the fixed shaft 1431 can move along its axial direction, thereby driving the winding core 132 to move, thereby causing the winding core 132 to abut against or disengage from the inner wall of the housing 131 .

[0071] It should be understood that when the winding core 132 is in contact with the inner wall of the housing 131, the winding core 132 cannot rotate, and thus the telescopic harness device 130 is in a locked state. When the winding core 132 is disconnected from the inner wall of the housing 131, the winding core 132 can rotate, indicating that the telescopic harness device 130 is in an open state.

[0072] In this way, the bracket clamping mechanism 141 and the telescopic harness device 130 can be simultaneously in an open state or a locked state by adjusting the handle 142 .

[0073] It should be understood that when the retractable wire harness device 130 is in a released state, the wire harness 133 can be pulled out of both ends of the housing 131 to overcome the elastic force of the first elastic member 134 and allow the winding core 132 to rotate to extend the wire harness 133 .

[0074] By loosening the two ends of the wire harness 133 extending out of the housing 131, the winding core 132 is rotated under the elastic force of the first elastic member 134 to retract the wire harness 133. In this way, the length of the wire harness 133 can be adjusted.

[0075] In a specific application, the first elastic member 134 and the second elastic member 1411 can be, for example, a power spring, a torsion spring, a telescopic spring, etc., which can be selected according to needs.

[0076] In some optional embodiments, the steering column assembly 100 further includes a clamping ring 120 , which is disposed at one end of the steering column 110 .

[0077] A transfer interface (not shown) is provided on one side of the clamping ring 120 close to the telescopic harness device 130 , and a first connector 135 is provided on one end of the harness 133 close to the clamping ring 120 . The first connector 135 is plugged into the transfer interface.

[0078] In this embodiment, a clamping ring 120 is provided at one end of the steering column 110, and the clamping ring 120 is provided with a switching interface. The switching interface is located on the side of the clamping ring 120 close to the telescopic wiring harness device 130, and the switching interface is used to fix the first connector 135 at one end of the wiring harness 133.

[0079] It should be understood that various front-end cables that need to be connected to the telescopic harness device 130 can be integrated into the adapter interface in the clamp ring 120, so as to achieve electrical connection with the telescopic harness device 130, which is conducive to improving the degree of integration.

[0080] Furthermore, the clamping ring 120 includes an open-loop hoop platform 121 and a locking plate 122 . The locking plate 122 is movably connected to the open-loop hoop platform 121 and is fitted onto the steering column 110 together with the open-loop hoop platform 121 . The adapter interface is located at the open-loop hoop platform 121 .

[0081] In this embodiment, the locking piece 122 is movably connected to the open-loop hoop 121 and is located at the open side of the open-loop hoop 121 , so that it can cooperate with the open-loop hoop 121 to form a closed-loop clamping ring 120 to be sleeved on one end of the steering column 110 .

[0082] exist Figure 3 In the illustrated embodiment, a rotating shaft is formed at one end of the locking plate 122 to be pivotally connected to the open-loop hoop 121 , and the other end of the locking plate 122 can be fixed to the open-loop hoop 121 by a screw 123 , and the tightness can be adjusted.

[0083] See also Figure 2 In some optional embodiments, the steering column assembly 100 further includes a motor 150 , which is connected to the steering column 110 and is located at an end of the steering column 110 away from the clamp ring 120 .

[0084] The locking adjustment structure 140 and the telescopic harness device 130 are located between the clamping ring 120 and the motor 150 . A second connector 136 is provided at one end of the harness 133 close to the motor 150 . The second connector 136 is connected to the motor 150 .

[0085] In this embodiment, a clamping ring 120 and a motor 150 are respectively disposed at both ends of the steering column 110, and the clamping ring 120 is located at one end close to the steering wheel 200. The locking adjustment structure 140 and the telescopic harness device 130 are located in the middle of the steering column 110, that is, between the clamping ring 120 and the motor 150.

[0086] Furthermore, a first connector 135 and a second connector 136 are respectively provided at both ends of the wire harness 133 in the telescopic wire harness device 130 , and the first connector 135 and the second connector 136 are respectively connected to the clamping ring 120 and the motor 150 on both sides.

[0087] In a specific application, the first connector 135 and the second connector 136 are standardized electrical connectors, and the wiring harness 133 integrates the electric control line and the power line of the motor 150, and the motor 150 is used to assist steering.

[0088] See also Figure 1 In some optional embodiments, the steering system further includes a steering intermediate shaft 300 , one end of which is movably connected to an end of the steering column 110 away from the steering wheel 200 .

[0089] In this embodiment, one end of the steering intermediate shaft 300 is connected to one end of the steering column 110 close to the motor 150. The steering intermediate shaft 300 is mainly used to transmit the rotational torque input through the steering wheel 200 and transmit it to the steering gear to achieve steering.

[0090] In a specific application, one end of the steering intermediate shaft 300 is hinged to one end of the steering column 110 to ensure that the steering intermediate shaft 300 can rotate to transmit the rotational torque.

[0091] In combination with the above, it can be known that when the position of the steering wheel 200 needs to be adjusted, the adjustable handle 142 is loosened. In the process of pulling out the steering wheel 200, the steering column 110 is stretched, the distance between the telescopic harness device 130 and the motor 150 increases, and the harness 133 extends to adapt to the change in the length of the steering column 110.

[0092] During the process of retracting the steering wheel 200 , the steering column 110 retracts, the distance between the telescopic wire harness device 130 and the motor 150 decreases, and the wire harness 133 retracts to adapt to the change in the length of the steering column 110 .

[0093] After the position adjustment of the steering wheel 200 is completed, the adjustable handle 142 is locked. In this way, the telescopic harness device 130 is in a locked state, and the harness 133 has no retraction tendency, thereby ensuring the connection reliability of the first connector 135 and the second connector 136.

[0094] Another aspect of the present application further provides a vehicle, the vehicle comprising the above-mentioned steering system. It should be understood that since the vehicle is equipped with the above-mentioned steering system, it obviously has all the advantages brought by the above-mentioned steering system, and no further description is given here.

[0095] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
