Technical Field

[0001] This utility model relates to the field of vehicle steering system technology, and in particular to a new energy passenger and freight steering column. Background Technology

[0002] In the automotive industry, the steering column is a crucial component connecting the steering wheel and steering gear, and its performance directly impacts driving control and safety. For new energy vehicles, due to their dual passenger and freight transport applications, the demands on driver posture and vehicle safety under various operating conditions are even higher. Traditional steering columns have several shortcomings. For example, the mounting brackets are often welded separately for the left and right sides, resulting in lower precision, greater weight, and lower production efficiency; in the event of a collision, they lack an effective buffer structure, providing insufficient protection for the driver; and they are difficult to adjust flexibly to accommodate different driver habits and the dual passenger / freight transport needs of the vehicle.

[0016] The present invention will be further described below.

[0017] See attached document Figures 1-2 A new energy passenger / freight dual-purpose steering column includes a bracket assembly 8, a column tube assembly 3, a steering shaft 1, a universal joint fork assembly 4, and an adjustment component 9. The steering shaft 1 is supported within the column tube assembly 3 by a bearing 2, with one end extending out of the column tube assembly 3 and connecting to the universal joint fork assembly 4. The universal joint fork assembly 4 is connected to the vehicle steering gear via a steering drive shaft 5 and a drive shaft sleeve 6 to transmit steering power. An oil seal 7 is provided at the connection point between the drive shaft sleeve 6 and the steering drive shaft 5 for sealing.

[0018] The steering column assembly 3 is connected to the bracket assembly 8 via the adjustment component 9. The steering column assembly 3 is provided with a first front-to-rear adjustment groove 31 and a second front-to-rear adjustment groove 32 for adjusting the front-to-rear position. The bracket assembly 8 includes a base plate 81 and a mounting bracket 82. The mounting bracket 82 is an integral U-shaped structure, fixed to the base plate 81 by welding or bolts. Multiple mounting holes are provided on the bottom of the U-shape and on the base plate 81. An angle adjustment groove 83 is provided on the side plate of the mounting bracket 82, providing space for adjusting the angle of the steering column, allowing the steering column to be adjusted within the groove range to meet the driving posture requirements of different drivers. A protrusion 84 extending into the groove is provided within the angle adjustment groove 83, which acts as a crumple zone. In the event of a collision, it can partially break, allowing the steering wheel to move forward, providing a buffer space for the driver's head, reducing the injury to the driver from a collision, and improving the vehicle's safety performance.

[0019] The adjustment component 9 includes a fastener 91, an adjustment bolt 92, a locking block 94, and a handle 93. By rotating the handle 93, the adjustment component 9 can switch between a locked state and an unlocked state. In the unlocked state, the bracket assembly 8 and the column tube assembly 3 can generate relative displacement for position adjustment. In the locked state, the bracket assembly 8 and the column tube assembly 3 are relatively fixed.

[0020] The fastener 91 passes through the mounting bracket 82 and the first front-to-back adjustment groove 31 and is fixed by a nut. The adjusting bolt 92 passes through the mounting bracket 82 and the second front-to-back adjustment groove 32 and is threadedly connected to the locking block 94. The locking block 94 is fixedly connected to the handle 93 by a bolt.

[0021] like Figure 3 As shown, the steering drive shaft 5 includes a drive shaft body 51. One end of the drive shaft body 51 is connected to the universal joint fork assembly 4 via a spline, and the other end is provided with a ball bearing carrier 52. Several axial grooves are evenly distributed on the outer circumferential surface of one end of the drive shaft body 51. The ball bearing carrier 52 is mounted on the drive shaft body 51 through its inner protrusion engaging with the axial grooves, and a clamp is provided on its end face. Several sets of ball mounting slots are evenly distributed along the axial direction on the ball bearing carrier 52, and balls 53 are disposed in the ball mounting slots. The steering drive shaft 5 and the drive shaft sleeve 6 cooperate using rolling friction, further optimizing the smoothness of steering torque transmission and reducing energy loss. An oil seal 7 is provided at the connection between the steering drive shaft 5 and the drive shaft sleeve 6, serving a sealing function to prevent dust, moisture, and other impurities from entering the steering column, avoiding wear of internal components due to contamination, and extending the service life of the steering column.

[0022] In practice, the driver can adjust the position of the steering column within the first front-to-rear adjustment groove 31, the second front-to-rear adjustment groove 32, and the angle adjustment groove 83 by operating the handle 94, in conjunction with the adjusting bolt 92 and the fastener 91, to achieve a suitable driving posture. In the event of a collision, the protrusion 84 will collapse and break, allowing the steering wheel to move forward further, providing cushioning for the driver's head and reducing injury. Simultaneously, the integrated U-shaped mounting bracket 82 ensures the precision and ease of installation of the steering column, improving production efficiency.
