It realizes crumple effect, and simplifies the components and structure of crumple, reduce cost and facilitate production, meanwhile, convenient for crumple energy
Design, convenient for manufacture processing, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme: a kind of shrinkable energy-absorbing electric power-assisted steering tubular column
Mounting bracket, including steering column ontology, steel plate and steel band, the steering column ontology are connected with support by nut thread
Frame, the steel plate are installed on the side of support frame, and the steel band is installed on the side of support frame, and the side of the steel band passes through spiral shell
Bolt is connected with the side of steel plate, and the side that the steel plate closes on bolt is provided with groove, the side of the groove and the side of bolt
Relatively, the side of the steel band is staggeredly provided with groove, and the side of groove described in every group is provided with notch, the steering column ontology
Side link block is installed, the side of support frame as described above is connected by spring with the side of link block.
Preferably, the steel band closes on the arc-shaped setting in side of support frame, and the steel band with a thickness of 1mm.
Preferably, the width of the groove is 1.5mm-2mm, and the groove side opposite with bolt is provided with through-hole.
Preferably, the length of the groove is 9mm, and the groove is provided at least four groups.
Preferably, notch setting triangular in shape, and the notch is symmetrically arranged with two groups relative to groove.
Preferably, the side of the link block and steel band is mounted on the support rod for fixed spring angle pawl, and described
Diagonal brace is installed between link block and steering column ontology.
Compared with prior art, the beneficial effects of the present invention are: being provided with groove by the side in bolt, by the one of bolt
Side is welded on the side of instrument beam, and when steering column ontology is collided, steering column ontology and support frame stress are mobile,
This results in support frame mobile with steel plate, so that the groove and threaded bolt contacts of steel plate side, bolt compresses groove position, so that
Groove position tears crumple energy-absorbing, absorbs local collision power, then turns to tubular column main body and support frame continues the mobile stress of stress
Mobile, at this point, bolt falls off from groove position, steel band starts to be straightened and tearing steel strip, steel band crumple are inhaled along groove
Impact force is received, collision energy is absorbed jointly by tearing steel strip and steel plate, to play the mesh for protecting driver in collision
, and effectively simplify structure, by the depth of adjusting grooves and the quantity of groove, easy realization to crumple can adjusting,
Facilitate design.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: a kind of shrinkable energy-absorbing electric power-assisted steering tubular column installation
Bracket, including steering column ontology 1, steel plate 2 and steel band 3, the steering column ontology 1 are threaded with support by nut 4
Frame 5, the steel plate 2 are installed on the side of support frame 5, and the steel band 3 is installed on the side of support frame 5, the side of the steel band 3
It is connected by bolt 6 with the side of steel plate 2, the side that the steel plate 2 closes on bolt 6 is provided with groove 7, the side of the groove 7
Opposite with the side of bolt 6, the side of the steel band 2 is staggeredly provided with groove 8, and the side of groove 8 described in every group is provided with notch
9, the side of the steering column ontology 1 is equipped with link block 10, and the side of support frame as described above 5 passes through spring 11 and link block 10
Side be connected, spring 11 absorbs the energy of the initial crumple in part.
Specifically, the arc-shaped setting in side that the steel band 3 closes on support frame 5, and the steel band 3 with a thickness of 1mm, protect
Demonstrate,prove the good crumple effect of steel band 3.
Specifically, the width of the groove 7 is 1.5mm-2mm, and the side opposite with bolt 6 of the groove 7 be provided with it is logical
Hole 12, through-hole 12 facilitate the crumple energy-absorbing at 7 position of groove.
