Detailed Description

As shown in fig. 1 to 5, the steering column mounting bracket structure of the automobile in the embodiment includes a worm gear housing 10 and a mounting bracket 20 detachably connected to the worm gear housing 10, a sleeve 11 for mounting a motor 40 is disposed on the worm gear housing 10, a connecting member 21 for connecting with a steering support 50 is disposed on the mounting bracket 20, and a relative position between the connecting member 21 and the sleeve 11 is adjustable. Connecting piece 21 is connected with steering support 50, sleeve 11 is connected with motor 40, connecting piece 21 is adjustable with sleeve 11's relative position, thereby it is adjustable to have realized that motor 40 arranges the angle, the commonality is high, when carrying out the steering column assembly of new motorcycle type and arranging the design, can arrange the angle in order to adapt to whole car through selecting suitable motor 40 and arrange, thereby it can compatible many motorcycle types to satisfy same money steering column assembly, need not redesign die sinking, reduce development cost, shorten the preparation cycle.

In this embodiment, a first mounting hole 13 is disposed in the middle of the worm housing 10, a second mounting hole 22 is disposed in the middle of the mounting bracket 20, and the axis of the first mounting hole 13 coincides with the axis of the second mounting hole 22. The steering column shaft 60 passes through the first mounting hole 13 and the second mounting hole 22, and the axis of the first mounting hole 13 is coincident with the axis of the second mounting hole 22, so that the first mounting hole 13 and the second mounting hole 22 do not interfere with the steering column shaft 60 when the relative position of the connecting piece 21 and the sleeve 11 is adjusted.

In this embodiment, M threaded holes 14 are formed in one side of the worm gear housing 10 facing the mounting bracket 20 at equal intervals along the circumferential direction of the first mounting hole 13, N through holes are formed in positions on the mounting bracket 20 corresponding to the threaded holes 14, and M > N is greater than or equal to 2; the bolt structure further comprises N bolts 30, wherein the N bolts 30 respectively penetrate through the N through holes and are in threaded connection with the N threaded holes 14. Since the M threaded holes 14 are circumferentially distributed at equal intervals, and the N through holes correspond to the positions of some of the threaded holes 14, the mounting bracket 20 can be rotated by using the axis of the first mounting hole 13 as a rotating shaft, so that the N through holes correspond to different threaded holes 14 to realize the relative rotation of the worm gear housing 10 and the mounting bracket 20, thereby adjusting the relative position of the connecting member 21 and the sleeve 11. For example: the number of the bolts 30 is two, the number of the threaded holes 14 is three, and the number of the through holes is two, so that the three threaded holes 14 are distributed at equal intervals on the circumference, and the two through holes correspond to the positions of two of the threaded holes 14, which means that the two through holes can be matched with any two of the three threaded holes 14, and the fixation is realized through the two bolts 30, and at the moment, three connection modes of the worm gear housing 10 and the mounting bracket 20 exist, namely, three relative positions of the connecting piece 21 and the sleeve 11 exist; similarly, in the present embodiment, the principle of adjusting the relative position of the connecting member 21 and the sleeve 11 with M =12 and N =4 is as described above, and therefore, the description thereof is omitted.

In this embodiment, the mounting bracket 20 is provided with a first through hole, a second through hole, a third through hole and a fourth through hole, and the connecting member 21, the first through hole, the second through hole, the third through hole and the fourth through hole are sequentially arranged along the clockwise direction of the circumference of the second mounting hole 22. The mounting position is reserved for the connecting piece 21 on the mounting bracket 20 between the first through hole and the fourth through hole, so that each part of the mounting bracket 20 is more compact, the size of the mounting bracket 20 is reduced, and the space utilization rate is increased.

In the embodiment, M =12, the circle centers of two adjacent threaded holes 14 are respectively a point a and a point B, the circle center of the first mounting hole 13 is a point O, and angle AOB =30 °; the circle centers of the first through hole, the second through hole, the third through hole and the fourth through hole are a point C, a point D, a point E and a point F in sequence, the circle center of the second mounting hole 22 is a point P, and angle CPD = DPE = EPF =60 °. The corresponding mating relationship of each bolt 30, each threaded hole 14 and each mounting hole is shown as four leads in fig. 1. Angle CPD = DPE = EPF =60 °, so the line of point C and point F is through point P, consequently two bolts 30 that pass first through-hole and fourth through-hole can fix a position the both sides of installing support 20, cooperate two other bolts 30 to make fixed reliable stable simultaneously, make the distribution of each installation point comparatively dispersed and even under the mounted position's of assurance connecting piece 21 the circumstances.

In this embodiment, the connecting member 21 includes a U-shaped connecting plate and a sleeve disposed on the U-shaped connecting plate. The sleeve is adapted to be connected to the steering support 50 and the U-shaped web is adapted to secure the sleeve.

In this embodiment, the axis of the sleeve is perpendicular to the axis of the second mounting hole 22; the axis of the sleeve 11 is perpendicular to the axis of the first mounting hole 13. The sleeve is positioned outside the second mounting hole 22, and the axis of the sleeve is not intersected with the axis of the second mounting hole 22 and is not in the same plane; the sleeve 11 is positioned outside the first mounting hole 13, and the axis of the sleeve 11 does not intersect with the axis of the first mounting hole 13 and is not in the same plane.

In this embodiment, the sleeve 11 is provided with two support lugs 12, and the two support lugs 12 are both provided with a connecting hole. The connecting holes on the two support lugs 12 are matched with the two holes on the motor 40, and the motor 40 is fixed through a fastener.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
