Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in figures 1 to 6, the anti-abnormal sound structure of the adjusting of this steering column includes fixed cam 1 and is used for and fixed cam 1
The rotation cam 2 of cooperation, there are four teeth portion 21 for the lower surface tool of rotation cam 2, and there are four along week for the upper surface tool of fixed cam 1
To the boss 11 being evenly arranged, the side of boss 11 is equipped with the slope surface 12 of the opposite sliding with teeth portion 21, the other side table of boss 11
Face is covered with anticollision otic placode 3, and anticollision otic placode 3 is rubber parts, and rubber parts elasticity is good, and anti-abnormal sound effect is good, and teeth portion 21 can be anti-with this
Otic placode 3 is hit to lean.Rotation cam 2 is manipulated when being adjusted to steering column and is relatively fixed the rotation of cam 1, rotates cam 2 at this time
The teeth portion 21 coordinated with fixed cam 1 is slided up and down with respect to the slope surface 12 of 11 side of boss, makes rotation cam 2 and fixed cam 1
Between gap variation, the release of steering column and locking are controlled from realizing.When operation rotation cam 2 resets, teeth portion
21 can be accelerated the side rigid collision with boss 11 downwards by elastic force effect along slope surface 12, abnormal sound be caused, by boss 11
Side covers flexible anticollision otic placode 3, in this way when the teeth portion 21 for rotating cam 2 is hit to the side of boss 11, with anticollision
3 Elastic Contact of otic placode, substantially reduces abnormal sound, improves anti-abnormal sound effect.For further, the periphery of fixed cam 1 is arranged with branch
Pushing out ring 4, the integrated molding of the outer end and support ring 4 of anticollision otic placode 3.Whole bonding strength and stability are promoted, and can be reduced
Assembly process.By being arranged the support ring 4 being connect with anticollision otic placode 3 in the periphery of fixed cam 1, such support ring 4 is anticollision
Otic placode 3 provides installation support, avoids falling off during 3 use of anticollision otic placode, improves stability in use, and support ring 4 is by anticollision
Otic placode 3 is integrated, and support ring 4, which is set in 1 periphery of fixed cam, can be realized integrally-built assembly, improve install convenient.
Preferably, the upper surface of support ring 4 circumferentially have it is several upwardly extend the protrusive board 41 to be formed, the medial surface of protrusive board 41 with it is convex
The lateral surface of platform 11 mutually reclines, and side and the anticollision otic placode 3 of the protrusive board 41 are fixedly connected with.By being arranged in the upper surface of support ring 4
The protrusive board 41 being connected with anticollision otic placode 3, protrusive board 41 can play a supporting role to anticollision otic placode 3 from another dimension, and it is steady to improve structure
Qualitative, the lateral surface of the medial surface for making protrusive board 41 and boss 11 mutually reclines, and such anticollision otic placode 3 and protrusive board 41 can be same with boss 11
When recline positioning, improve structure installation accuracy and convenience.
As shown in Figure 3, Figure 4, the peripheral both sides of fixed cam 1 have a section 13 in plane, the inner edge of support ring 4 with cut
13 phase of face reclines.In the section 13 of plane and the inner edge of support ring 4 is made to be pasted with section 13 by the periphery setting in fixed cam 1
By cooperation, avoids support ring 4 around 1 rotation of fixed cam, improve the stability of structure.Wherein the middle part of a section 13 has outside
The stage portion 14 of protrusion, inner edge and 14 outer surface of stage portion of support ring 4 mutually recline.It is outside by the middle part setting in section 13
The stage portion 14 of protrusion simultaneously makes the inner edge of support ring 4 and 14 outer surface of stage portion recline cooperation, further increase in this way support oneself
The resistance turned, improves the stability of structure.
