The left and right directions of " length direction " in Fig. 3 in the utility model, right and left of the "left", "right" in Fig. 4-5
To.The vertical direction of " short transverse " along Fig. 3-5.
In the present embodiment, as in Figure 3-5, steering column includes column casing 1 and column sleeve 2, and column casing 1 is set in column
Outside set 2, the outer surface of column sleeve 2 is equipped with metal guide 7, connector 3 and plastic guide rail 4, and metal guide 7 is fixedly connected on
On the outer surface of column sleeve 2, one end and the metal guide 7 of connector 3 are interference fitted, and the other end of connector 3 is wedge block 31,
Wedge groove 41 is offered on plastic guide rail 4, wedge block 31, which is embedded into, makes the outer of wedge block 31 in the wedge groove 41 of plastic guide rail 4
Surface is bonded with the inner surface of wedge groove 41.
Wherein, column casing 1 is set in outside column sleeve 2, when length adjustment column sleeve 2 relative to column casing 1 in itself
Heart axis direction (i.e. length direction) is mobile.
Metal guide 7 can be welded on the outer surface of column sleeve 2, and connector 3 is interference fitted with metal guide 7, modeling
Expect that guide rail 4 is mounted in the elongated slot of column casing 1, during length adjustment, connector 3 and column sleeve 2 are with electric machine connecting support 9
It moves along its length together.Plastic guide rail 4 is fixed on fixed in the elongated slot of column casing 1.
As shown in Fig. 2, there are horizontal clearances 5 ' and vertical gap 6 ' between existing connector 3 ' and plastic guide rail 4 '.This
It is because what existing plastic guide rail 4 ' above opened up is rectangular channel, the other end of corresponding connector 3 ' is rectangular block.Due to square
Tolerance fit between shape block and rectangular channel so that it is difficult the horizontal clearance 5 ' eliminated and vertical gap 6 ' to exist.Work as length in this way
When degree is adjusted, since the metal guide 7 ' on connector 3 ' and column sleeve 2 ' is interference fitted, horizontal clearance 5 ' and vertical gap 6 '
Space is provided for the rotation or shaking of column sleeve 2 ' and connector 3 '.
As described in Figure 5, wedge groove 41 is offered on the plastic guide rail 4 in the present embodiment, the other end of connector 3 is wedge shape
Block 31, wedge block 31 is inserted into wedge groove 41 and the outer surface of wedge block 31 is bonded with the inner surface of wedge groove 41.
The present embodiment is by the cooperation of wedge block 31 and wedge groove 41, between eliminating between connector 3 and plastic guide rail 4
Gap limits the rotation or shaking of column sleeve 2 during length adjustment.
Further, as shown in figure 5, the cross section of wedge block 31 is inverted trapezoidal, wedge block 31 includes the first inclined-plane
311, the second inclined-plane 312 and the first bottom surface 313, wedge groove 41 include the first slope surface, the second slope surface and the second bottom surface, the first inclined-plane
311 are bonded with the first slope surface, and the second inclined-plane 312 is bonded with the second slope surface, and the first bottom surface 313 is bonded with the second bottom surface.
Since three faces of wedge block 31 are bonded with wedge groove 41 so that connector 3 and column sleeve 2 without rotation or shake
Dynamic space.
Alternatively it is also possible to which only the first inclined-plane 311 is bonded with the first slope surface, the second inclined-plane 312 is bonded with the second slope surface,
And the first bottom surface 313 is not bonded with the second bottom surface.Gap between first inclined-plane 311 and the first slope surface, the second inclined-plane 312 and
Gap between two slope surfaces can compress with connector 3 with the rising of plastic guide rail 4 and be eliminated.
Further, as shown in figure 5, steering column further includes pressing plate 5 and screw 6, screw 6 passes through pressing plate 5 so that pressing plate 5
Plastic guide rail 4 and connector 3 are compressed.
Pressing plate 5 for plastic guide rail 4 and connector 3 to be compressed, pressing plate 5 can push plastic guide rail 4 upwards until with company
Contact surface between fitting 3 is adjacent to, and pressing plate can also compress connector 3 and column sleeve 2.
Further, as shown in figure 5, being additionally provided with electric machine connecting support 9 between metal guide 7 and plastic guide rail 4, connection
Part 3 passes through electric machine connecting support 9.
When length adjustment, column sleeve 2, metal guide 7, electric machine connecting support 9 and connector 3 are moved with column sleeve 2 together, and
Plastic guides 4, pressing plate 5, screw 6 and column casing 1 are motionless.
Further, as shown in figure 5, offering elongated slot 11 on column casing 1, connector 3 and plastic guide rail 4 are housed in length
It is interference fit between the lateral surface and the madial wall of elongated slot 11 of plastic guide rail 4 in slot 11.
Specifically, metal guide 7, a part for electric machine connecting support 9 and connector 3 are housed in column casing 1.
When length adjustment, these components can along its length slide in elongated slot 11.
It is interference fit between the left and right side and the left and right sidewall of elongated slot 11 of plastic guide rail 4 so that plastic guide rail 4 is in length
It is relatively motionless between elongated slot 11 when degree is adjusted, and guiding role is played to connector 3, metal guide 7 and column sleeve 2.
In the present embodiment, the gap between connector 3 and plastic guide rail 4 is eliminated after being compressed by pressing plate 5.Therefore length tune
It will not occur significantly to shake or rotate when section, between connector 3 and plastic guide rail 4.And existing connector 3 ' and plastics are led
Gap is likely to be breached 0.5mm between rail 4 ', therefore generates and shake or rotate larger, needs to overcome.
Further, steering column further includes length adjustment motor (not shown), and length adjustment motor drives column sleeve 2 along length
It is flexible to spend direction.
Further, steering column further includes height adjustment motor (not shown), and height adjustment motor drives column sleeve 2 along height
Spend direction movement.
Above-described is only the principles of the present invention and preferred embodiment.It should be pointed out that for the general of this field
For logical technical staff, on the basis of the utility model principle, several other modifications can also be made, this practicality is also should be regarded as
Novel protection domain.
