Detailed description of the invention
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1 to Fig. 3, Fig. 1 is the integral structure schematic diagram of steering column electric adjusting mechanism disclosed in the utility model embodiment, Fig. 2 is the front elevational schematic of steering column electric adjusting mechanism disclosed in Fig. 1, and Fig. 3 is the detonation configuration schematic diagram of steering column electric adjusting mechanism disclosed in Fig. 1.
In steering column electric adjusting mechanism disclosed in the utility model, comprising lower tubular column 1, being plugged on upper tubing string 2 in lower tubular column 1 and the mounting bracket 3 for being fixedly linked with car load, what needs were described is, the circumference being plugged on the upper tubing string 2 in lower tubular column 1 is fixing, namely go up tubing string 2 to rotate relative to lower tubular column 1, bottom and the mounting bracket 3 of lower tubular column 1 are hinged, as shown in fig. 1, and this steering column regulating mechanism also comprises angular adjustment motor 4, first speed reduction gearing, nut slider 6 and turret 7.
Angular adjustment motor 4 is fixedly installed on lower tubular column 1, both can be dismountable being fixedly connected with, also can be permanent being fixedly connected with, the removable connection mode of preferred employing in the present embodiment, angular adjustment motor 4 is bolted and is arranged on lower tubular column 1; The input end of the first speed reduction gearing coordinates with the output shaft of angular adjustment motor 4, and the first speed brake setting is arranged on angular adjustment motor 4, and as shown in fig. 1, the mouth of the first speed reduction gearing is the first screw rod 5 with the axis being parallel of lower tubular column 1; Nut slider 6 and the first screw rod 5 adaptation; Turret 7 is hinged with lower tubular column 1 by the first jointed shaft 8, hinged with mounting bracket 3 by the second jointed shaft 9, hinged with nut slider 6 by the 3rd jointed shaft 10, second jointed shaft 9 is lower than the first jointed shaft 8, and the first jointed shaft 8, second jointed shaft 9 is all vertical with lower tubular column 1 with the 3rd jointed shaft 10.
Be connected with steering hardware because steering column one end when actual installation is positioned at bottom, the other end is positioned at top and is connected with bearing circle, the D score thus in the utility model embodiment and " on " just represent D score in vertical direction and " on ".
When needs carry out angular adjustment to steering column, angular adjustment motor 4 operates, and then drive the first screw rod 5 to rotate, because the first speed brake setting is arranged on angular adjustment motor 4, and angular adjustment motor 4 is fixedly installed on lower tubular column 1, thus with the nut slider 6 of the first screw rod 5 adaptation, the axis along the first screw rod 5 is moved up and down, nut slider 6 drives lower tubular column 1 to rotate by turret 7, the center rotated is the jointed shaft of lower tubular column 1 bottom and mounting bracket 3, this just make lower tubular column 1 upper end can near or away from mounting bracket 3, thus reach the object of angle of steering tubular column adjustment.
Visible, steering column electric adjusting mechanism disclosed in the utility model embodiment, is moved by driven by motor steering column, changes the angle between steering column and mounting bracket 3, thus reaches the object of angle of steering tubular column adjustment.Compared to traditional manual regulation, not only time saving and energy saving, and the stability that can effectively improve when steering column carries out angular adjustment and ride comfort, avoid steering hardware and occur abnormal sound, improve the quality of car load and the ride comfort sense of passenger.
Be understandable that, in order to reduce the rotating speed of motor, promote the stationarity of steering column control process, speed reduction gearing is necessary, and in the present embodiment, the output shaft of angular adjustment motor 4 is specially worm gear, and the first speed reduction gearing is the worm screw with this worm wheel.Worm gear structure, while reaching deceleration object, can also effectively reduce the installing space shared by speed reduction gearing, promotes the convenience that whole steering column electric adjusting mechanism is installed.Certainly, when installing space allows, the first speed reduction gearing can also be gear reducer.
Understandable, the concrete shape of turret 7 is unrestricted, such as, can be a triangle in the form of sheets, and a leg-of-mutton angle is used for coordinating with the first jointed shaft 8, matches with the second jointed shaft 9 and the 3rd jointed shaft 10 respectively in two other angle.A kind of turret 7 in " H " type is provided in the present embodiment, as shown in Figure 1, Figure 3 and Figure 4, nut slider 6 is inserted in one end of this turret 7, and it is hinged with nut slider 6, the other end of turret 7 is inserted in lower tubular column 1, and the top of this end and bottom respectively with lower tubular column 1 and mounting bracket 3 hinged.
Technical scheme disclosed in above-described embodiment only achieves the angular adjustment of steering column, and the height of unrealized steering column regulates, in the present embodiment, technical scheme disclosed in above-described embodiment is optimized, concrete, on the basis of above-described embodiment, also comprise in technical scheme disclosed in the present embodiment: telescopic adjustment motor 11, second speed reduction gearing and sliding part 13.Wherein, telescopic adjustment motor 11 is fixedly installed on lower tubular column 1 or on mounting bracket 3, the input end of the second speed reduction gearing coordinates with the output shaft of telescopic adjustment motor 11, and the mouth of the second speed reduction gearing is second screw rod 12 parallel with upper column axis, sliding part 13 is fixedly connected with upper tubing string 2, and offer the negative thread with the second screw rod 12 adaptation, as shown in fig. 1.
When needing to carry out the adjustment of Steering gear height, telescope motor 11 operates, and then drive the second screw rod 12 to rotate, because the second speed brake setting is arranged on telescopic adjustment motor 11, and telescopic adjustment motor 11 is fixedly installed on lower tubular column 1 or mounting bracket 3, thus with the sliding part 13 of the second screw rod 12 adaptation, the axis along the second screw rod 12 is moved up and down, tubing string in drive 2 is carried out up-and-down movement by sliding part 13, which achieves the change that tubing string 2 is inserted in lower tubular column 1 inner length, thus reach the object of steering column height adjustment.
As can be seen here, technical scheme disclosed in the present embodiment achieves the object of by motor, steering column being carried out to four-way adjustment, thus the stability improved further when steering column carries out angle and highly regulates and ride comfort, and the ride comfort sense of the quality of car load and passenger.
In order to reduce the rotating speed of motor, promote the stationarity of steering column control process, speed reduction gearing is necessary, and in the present embodiment, the output shaft of telescopic adjustment motor is also worm gear, and the second speed reduction gearing is the worm screw with this worm wheel.Worm gear structure, while reaching deceleration object, can also effectively reduce the installing space shared by speed reduction gearing, promotes the convenience that whole steering column electric adjusting mechanism is installed.Certainly, when installing space allows, the second speed reduction gearing also can be gear reducer.
Sliding part for coordinating with the second screw rod also has multiple choices, such as, can be and the nut of the second screw rod adaptation or screw thread bush, adopt screw thread bush as sliding part, as shown in Figures 1 and 2 in the utility model embodiment.And sliding part 13 is connected by a middleware indirectly with upper tubing string 2, certainly, when structure allows, sliding part 13 also directly can be connected with upper tubing string 2.
