It is moved at lower limit position, the centre position of flexible pipe assembly 8 is located among upper extreme position and lower limit position, when flexible
When pipe assembly 8 is located at upper extreme position, upper tubing string assembly 6 be in apart from lower tubular column assembly 7 most far from；Work as telescoping tube
When assembly 8 is located at lower limit position, upper tubing string assembly 6 is at the position nearest apart from lower tubular column assembly 7.
As shown in Fig. 8 to Figure 13, electronic four-way adjustable steering pipe column possesses upper and lower, the front and rear electronic adjustment function of four-way, on
Lower adjusting range is 0-45mm, and whole scope ± 9 ° of fore-aft adjustable, next possesses memory function, in the whole scope of upper and lower, fore-aft adjustable
It is interior, three to five different memory areas can be set.
The control method of electronic four-way adjustable steering pipe column for controlling said structure is as follows：
Controller judges whether to meet according to the vehicle-related information received adjusts electronic four-way adjustable steering pipe column
Condition, if meeting the condition for adjusting electronic four-way adjustable steering pipe column, controller sends related command to angle regulator 4
And/or axial-adjustment unit 5, angle regulator 4 and/or axial-adjustment unit 5 adjust electronic four according to the order received
To adjustable steering pipe column.
The vehicle-related information that controller receives includes speed and key gear signal, direction Regulate signal include it is upper,
Under, forward and backward four direction, the swing angle electric 413 and telescope motor 503 of controller and electronic four-way adjustable steering pipe column is are electrically connected
Connect, swing angle electric 413 and telescope motor 503 are controlled by controller.
Get on or off the bus for the ease of driver, electronic four-way adjustable steering pipe column can be arranged to automatic telescopic reset,
Steering wheel is set to be at forefront and uppermost position so as to avoid steering wheel when driver gets on or off the bus.Before steering wheel is in most
When place is put in orientation, the distance between steering wheel and front side instrument board are nearest；When steering wheel is at uppermost position, steering wheel with
It is nearest between the covering for roofs of vehicle.
The process that electronic four-way adjustable steering pipe column automatic telescopic resets includes the steps：
As shown in Figure 10, after vehicle parking stops working, key is in OFF grades, and controller receives misfire signals, and controller is defeated
Go out signal to be operated to angle regulator 4 and axial-adjustment unit 5, swing angle electric 413 and telescope motor 503, angle tune
The upper tubing string assembly 6 of the control of regulating device 4 rotates up, and upper tubing string assembly 6 drives the first steering spindle 1 and thereon while rotating up
Steering wheel synchronously rotate up, until upper tubing string assembly 6 is rotated to preceding extreme position, steering wheel be in forefront at this time
Put place；The flexible pipe assembly 8 of the control of axial-adjustment unit 5 moves axially upward, can be with while flexible pipe assembly 8 moves up
Tubing string assembly 6 in drive, the second steering spindle 2, the first steering spindle 1 and steering wheel thereon synchronously move up, until telescoping tube
Assembly 8 is moved at upper extreme position, and steering wheel is at lowermost position at this time.Electronic four-way adjustable steering pipe column is stretched automatically
After contracting resets, the flexible pipe assembly 8 of electronic four-way adjustable steering pipe column stretches to extreme higher position, and most anteposition is swung on swing pipe
Put, the space enough to driver, facilitates driver to get on and off, and improves the comfort and convenience of driving.
After driver gets on the bus igniting, vehicle launch, key is in ON grades, and controller receives ignition signal, and controller is defeated
Go out signal to be operated to angle regulator 4 and axial-adjustment unit 5, swing angle electric 413 and telescope motor 503, make to stretch
Pipe assembly 8 and upper tubing string assembly 6 return to memory area, and then steering wheel is automatically restored to memory area, are carried to driver
Convenience has been supplied, has improved comfort, the convenience of driving.
The present invention is exemplarily described above in association with attached drawing.Obviously, the present invention implements and from above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical solution are directly applied into other occasions, in protection scope of the present invention
Within.
