Description
Technical Field
The utility model relates to the technical field of steering columns, in particular to a spiral spring type noise reduction radial adjusting mechanism for a steering column.
Background
The adjustable steering column is provided with an upper column radial adjusting mechanism, so that a certain supporting force is provided when the steering wheel is radially adjusted, and the adjusting process is smooth and light.
Referring to fig. 1 and 2, the existing upper column tube radial adjusting mechanism comprises a handle small assembly 1, an adjusting spring 2, an upper column tube 3 and an outer support 4, wherein the handle small assembly 1 penetrates through a connecting support at the bottom of the upper column tube 3 and the outer support 4 and is fixed, and two ends of the adjusting spring 2 are installed in through holes of the outer support 4. The adjusting spring 2 has a complex shape and a relatively long length, and when the vehicle runs on a bumpy road, the spring vibrates, so that friction between metals is caused to generate noise.
As the requirements of automobile consumers on silence of the whole automobile are higher and higher, the texture requirements of steering wheel adjustment are gradually improved. Therefore, it is desirable to design a coil spring noise reduction radial adjustment mechanism for a steering column to improve adjustment feel and silence.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a spiral spring type noise reduction radial adjusting mechanism for a steering column, so as to improve adjusting texture and silence.
In order to achieve the above purpose, the utility model provides a spiral spring type noise reduction radial adjusting mechanism for a steering column, which comprises a handle small assembly, a bracket, a spiral spring and an upper column tube, wherein the bracket is sleeved outside the middle part of the upper column tube, the handle small assembly penetrates through the upper column tube and the bracket and is fixed, the inner surface of the bracket is provided with a protruding structure, the bottom of the upper column tube is provided with a groove corresponding to the protruding structure, the spiral spring is arranged between the inner surface of the bracket and the bottom of the upper column tube, the upper end of the spiral spring is embedded into the groove, and the protruding structure is embedded into the lower end of the spiral spring.
The spiral spring is cylindrical.
The spiral spring comprises a cold-drawn spring steel wire which is twisted and wound around an axis.
The section of the cold-drawn spring steel wire is round.
Compared with the prior art, the cylindrical spiral spring is arranged between the upper column tube and the support, and the two ends of the spiral spring are respectively fixed with the protruding structure of the support and the groove of the upper column tube, so that vibration of the spring is avoided, metal friction noise caused by the vibration is reduced, and the adjusting texture and silence are improved.

Description of the embodiments
The utility model will now be further described with reference to the accompanying drawings.
Referring to fig. 3 and 4, the utility model provides a spiral spring type noise reduction radial adjusting mechanism for a steering column, which comprises a small handle assembly, a bracket, a spiral spring and an upper column tube, wherein the bracket 6 is sleeved outside the middle part of the upper column tube 3, the small handle assembly 1 penetrates through the upper column tube 3 and the bracket 6 and is fixed, a protruding structure 61 is arranged on the inner surface of the bracket 6, a groove 31 corresponding to the protruding structure 61 in position is arranged at the bottom of the upper column tube 3, the spiral spring 5 is arranged between the inner surface of the bracket 6 and the bottom of the upper column tube 3, the upper end of the spiral spring 5 is embedded in the groove 31, and the protruding structure 61 is embedded in the lower end of the spiral spring 5.
The both ends of coil spring 5 act on upper column tube 3 and support 6 respectively, and protruding structure 61, recess 31 can prevent coil spring 5 axial displacement to fix the both ends of coil spring 5, avoid sending metal friction noise on jolting the highway section.
Referring to fig. 5, the coil spring 5 is cylindrical. The coil spring 5 comprises a cold drawn spring wire which is torsionally wound around an axis to save axial working space and to ensure that the coils of the coil spring 5 are pressed against each other when empty. The coils of the coil spring 5 thus produced have a certain compression force between them, and a certain pre-tightening force is also generated in the cold drawn spring wire. The cold-drawn spring steel wire has a circular section, and has the advantages that the load is not limited by directivity when stressed, and the bending strength in all directions is kept consistent.
The coil spring 5 has the characteristics of low cost, manufacturability, simple production process and the like, and can still achieve the full life cycle of the automobile due to smaller deformation although fatigue phenomenon can be generated along with the increase of the use times.
When the utility model works, after the handle small assembly 1 is loosened, the upper column tube 3 moves along with the handle small assembly 1 in the adjusting groove of the bracket 6, and the spiral spring 5 can be further bent or restored, so that the radial adjusting requirement of the upper column tube 3 is realized.
According to the utility model, the cylindrical spiral spring is arranged between the upper column tube and the support, and the two ends of the spiral spring are respectively fixed with the protruding structure of the support and the groove of the upper column tube, so that the vibration of the spring is avoided, the metal friction noise caused by the vibration is reduced, and the adjusting texture and silence are improved.
