Detailed Description

The invention will be further explained with reference to the drawings.

As shown in figure 1, the four-way adjusting steering column assembly comprises a support 1, an upper tubular column 2, a lower tubular column 3 and a steering shaft 4 arranged in the upper tubular column 2 and the lower tubular column 3, wherein the upper tubular column 2 and the lower tubular column 3 are both made of iron, the support 1 comprises a support seat 5, a limit plate 6 is arranged on the support seat 5, an adjusting hole 7 is arranged on the limit plate 6, the limit plate 6 is connected with a support sleeve 8 arranged at two sides of the outer wall of the upper tubular column 2, one side of the support sleeve 8, which is opposite to the limit plate 6, is provided with an adjusting handle 9, the adjusting handle 9 is connected with an adjusting shaft 10 inserted in the support sleeve 8 and the limit plate 6, the tail end of the adjusting shaft 10 is provided with an adjusting bolt 11 abutted against the limit plate 6, a spring 12 is arranged between the adjusting shaft 10 and the support seat 5, a pressing block 13 is arranged on the adjusting shaft 10, an annular portion 14 and a protruding portion 15, the upper pipe column 2 is provided with a through hole 16, and the pressing block 13 penetrates through the through hole 16 and is directly abutted against the outer wall of the lower pipe column 3.

The utility model provides a four-way steering column assembly of adjusting, at first its contrast prior art has low-cost advantage, and top tube post 2 among the prior art adopts the aluminium casting, and its cost is higher, and the productivity is lower, and application is on high joining in marriage the motorcycle type basically, and top tube post 2 in this scheme uses the iron pipe stamping workpiece and makes, and the cost reduction is a lot to production efficiency improves. In addition, in the prior art, in order to meet the sliding retaining force, the four-way adjusting pipe column adopts the mode that the aluminum upper pipe column 2 tightly holds the iron lower pipe column 3 to collapse, the sliding force is deviated from the lower limit, and if the sliding force needs to be increased, the handle force is also increased and exceeds the upper limit; the scheme adopts a mode that the adjusting handle 9 drives the pressing block 13 to compress the lower pipe column 3 to meet the sliding retaining force, and the sliding force can be adjusted under the condition that the influence on the force of the adjusting handle 9 is small. Specifically, the adjusting handle 9 is rotated, the adjusting handle 9 drives the adjusting shaft 10 and the pressing block 13 on the adjusting shaft 10 to rotate, the sliding retaining force is changed by changing the abutting joint of the annular part 14 on the pressing block 13 and the protruding part 15 with the lower tubular column 3, and the pressure between the pressing block 13 and the lower tubular column 3 is different due to the fact that the diameters of the annular part 14 and the protruding part 15 are different. The spring 12 is used for tensioning the adjusting rod and the pressing block 13, and the limiting plate 6 and the supporting sleeve 8 are used for supporting and guiding.

Preferably, the upper pipe column 2 is connected with a sliding bush 17 sleeved on the lower pipe column 3, and the pressing block 13 penetrates through the sliding bush 17 to be abutted against the lower pipe column 3. In the four-way adjusting pipe column in the prior art, the lower pipe column 3 is an iron piece, and the upper pipe column 2 is an aluminum piece, so that friction between the upper pipe column and the lower pipe column can generate a plurality of aluminum chips, and noise and other performance influences are brought; the structure of the scheme adopts the structure that the lower pipe column 3 is contacted with the sliding bush 17 made of the POM material, so that the noise can be reduced.

Preferably, a waist-shaped hole 18 is formed in the center of the pressing block 13, and the adjusting shaft 10 penetrates through the waist-shaped hole 18. This has the advantage that the pressure piece 13 is prevented from rotating relative to the adjusting shaft 10.

Preferably, an arc-shaped buffer part 19 is arranged between the annular part 14 and the convex part 15. The advantage of this arrangement is that the forces applied during the adjustment are relatively balanced.

Preferably, the outer wall of the upper pipe column 2 is provided with a supporting block 20 abutting against the supporting sleeve 8. This has the advantage of improving the stability of the connection of the upper string 2 to the support sleeve 8.
