FIG. 3 is a front view of a steering column noise reducing structure according to one embodiment of the present invention. Fig. 4 is a cross-sectional view taken at a-a in fig. 3. In one embodiment, as shown in FIG. 4, the noise reduction member 40 is "I" shaped and includes a tubular main body member 43 and first and second noise reduction blocks 41, 42 at opposite ends of the main body member 43.

When the noise reduction member 40 moves relative to the upper tube body 10 along with the handle assembly 30, the first side surface 411 and the second side surface 412 form clearance fit with the inner side surface of the first sliding groove 13 in the width direction, so that friction between the two is reduced to a certain extent, and the degree of freedom of the first noise reduction block 41 in the width direction of the first sliding groove 13 is limited.
Optionally, as shown in fig. 5, a rounded corner 415 is provided at an intersection of the first side 411 and the third and fourth sides 413, 414 of the first noise reduction block 41, a rounded corner 415 is also provided at an intersection of the second side 412 and the third and fourth sides 413, 414, and a middle of the third and fourth sides 413, 414 is recessed inwards.

In another embodiment, as shown in fig. 5, the first noise reduction block 41 is further provided with a first opening 416 and a second opening 417 penetrating through the thickness direction thereof, and the first opening 416 and the second opening 417 are respectively located near the inner sides of the third side 413 and the fourth side 414. The arrangement of the first and second openings 416 and 417 absorbs deformation of the first noise reduction block 41 and impact energy to some extent upon impact.
Alternatively, as shown in FIG. 5, the first opening 416 and the second opening 417 are both arc-shaped openings and the arcs are both curved inward such that the shape of the first opening 416 and the second opening 417 are as similar as possible to the shape of the first side 411 and the second side 412, resulting in more uniform deformation and energy absorption.
In one embodiment, as shown in fig. 5, the second noise reduction block 42 is a cylindrical block, and has a fifth side 421 and a sixth side 422 opposite to each other in the width direction and a first arc 423 and a second arc 424 opposite to each other in the length direction, the first arc 423 and the second arc 424 both protrude outward, the thickness direction of the second noise reduction block 42 is parallel to the axial direction of the main body 43, the length direction of the second noise reduction block 42 is parallel to the length direction of the second sliding chute 14, and the fifth side 421 and the sixth side 422 form a clearance fit with two inner sides in the width direction of the second sliding chute 14. The clearance fit here reduces the friction between the second noise reduction block 42 and the second slide groove 14, and restricts the degree of freedom of the second noise reduction block 42 in the width direction of the second slide groove 14.
Optionally, as shown in fig. 5, the maximum dimension L1 in the length direction of the first noise reduction block 41 is slightly larger than the maximum dimension L2 in the length direction of the second noise reduction block 42. When the noise reduction piece 40 of the present embodiment moves to the extreme positions at both ends relative to the upper pipe body 10, since the length of the first noise reduction block 41 is slightly larger, the noise reduction piece first collides with the first sliding groove 13 of the upper pipe body 10, and when the first noise reduction block 41 is deformed to a certain extent by collision extrusion, the second noise reduction block 42 collides with the second sliding groove 14, so as to prevent the first noise reduction block 41 from being deformed too much and being unable to rebound.
In one embodiment, as shown in FIG. 1, the handle assembly 30 includes an adjustment handle body 31, a connecting bolt 32, and a nut 33. As shown in fig. 4, the connecting bolt 32 is passed through the adjustment handle body 31, the fixture 20, the noise reducer 40, and the upper pipe body 10 and is tightened at one end with the nut 33, thereby fixedly connecting the adjustment handle body 31, the fixture 20, the noise reducer 40, and the upper pipe body 10.
In one embodiment, as shown in fig. 5, the noise reducer 40 is provided with a through hole 44 penetrating the main body piece 43 in the axial direction thereof for passing the attachment bolt 32 (see fig. 4).
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
