313 angle is 90 degree.
In a preferred embodiment of the invention, the Anti-fall portion 32 includes and the column mounting bracket body 21
The canned paragraph 321 that fits of surface, be provided with fixing hole 3211 on the canned paragraph 321, so, Anti-fall portion 32 closely may be used
It is fixed together with column mounting bracket body 21 by ground, so as to preferably play 1 anti-lost drop of steering column.
In order to preferably avoid steering wheel and steering column 1 from dropping from automobile tube beam completely, the Anti-fall portion 32 is also
Including the vertical section 322 and linkage section 323 that are sequentially connected with, the vertical section 322 is connected with the canned paragraph 321, the company
Connect section 323 to be connected with the construction section 313；The canned paragraph 321 and the linkage section 323 are parallel with the construction section 313,
The vertical section 322 is parallel with the inverted sections 312.Certainly, the junction between canned paragraph 321 and vertical section 322 is preferred
Ground rounding off, the preferably rounding off of the junction between vertical section 322 and linkage section 323.When positioning section 311 and inverted sections
When 312 angle is 90 degree, the angle of canned paragraph 321 and vertical section 322 is also 90 degree；The folder of inverted sections 312 and construction section 313
When angle is 90 degree, vertical section 322 is also 90 degree with the angle of linkage section 323.
Further, it is additionally provided with via hole 314 on the Anti-fall rack body 31, the via hole 314 is from described
Inverted sections 312 extend to the construction section 313；The vertical section 322 and the linkage section 323 are located in the via hole 314,
And the vertical section 322 is in the same plane with the inverted sections 312, preferably to avoid steering wheel and steering column 1 complete
Drop from automobile tube beam entirely.
Further, the linkage section 323 is non-coplanar with the construction section 313, and the edge of the linkage section 323 with
Connection sheet 33 is provided between the edge of the via hole 314, and the connection sheet 33 is arranged with the junction of the via hole 314
Fluted 331, the height of the groove 331 is less than the thickness of the construction section 313.So, when 1 crumple of steering column, with
The Anti-fall portion 32 that column mounting bracket body 21 links together is moved along the crumple direction of steering column 1, due to connection
The junction of piece 33 and via hole 314 is provided with groove 331 of the height less than the thickness of construction section 313, thus with Anti-fall portion
Separate with Anti-fall rack body 31 readily along groove 331 after 32 33 stress of connection sheet for linking together, so as to Anti-fall
32 part of portion is separated along connection sheet 33 with Anti-fall rack body 31, and this set desirably prevents steering column 1 too fast routed
Contracting, to avoid causing secondary injury to driver.
As shown in Figure 6, in this embodiment, when steering column 1 occurs crumple, connect with column mounting bracket body 21
The Anti-fall portion 32 being connected together is moved along the crumple direction of steering column 1, the canned paragraph 321 in Anti-fall portion 32 and vertical section
322, the angle between vertical section 322 and linkage section 323 changes；With the continuation crumple of steering column 1, Anti-fall portion 32
The crumple power passed over from column mounting bracket body 21 is passed to into Anti-fall rack body 31, now Anti-fall support sheet
The positioning section 311 and inverted sections 312 of body 31, the angle between inverted sections 312 and construction section 313 change, not only can be effective
Avoid steering wheel and steering column 1 from dropping from automobile tube beam completely, and desirably prevent 1 too fast crumple of steering column,
Preferably avoid causing secondary injury to driver.
In another preferred embodiment of the present invention, Anti-fall support 3 also includes to be engaged with the fixing hole 3211,
So that the Anti-fall portion 32 is fixed on the fixing rivet (not shown) on the column mounting bracket body 21, the company
Connect, so, when fixing rivet is installed, fixing rivet can be from rivet via 3231
Pass through, to facilitate the installation of fixing rivet.
In order to improve the intensity of Anti-fall support 3, simplify its preparation technology, the Anti-fall support 3 is formed in one knot
Structure.
Although the present invention is described with reference to above example, the present invention is not limited to above-described embodiment,
And be only defined by the appended claims, those of ordinary skill in the art easily can modify and change to which, but and
Essential idea and scope without departing from the present invention.
