For the telescopic adjustment of steering column 200, be realized by the translation of steering column drive spindle 1, such as steering column drive spindle 1 just can realize the flexible of steering column 200 to left or to right translation.Specifically, now first clutch 61 combines, and second clutch 62 disconnects, actuator 5 one aspect drives the first leading screw 21 to rotate by the first output gear wheels 41, first leading screw 21 can drive the first screw 22 to right translation, on the other hand, actuator 5 is by first clutch 61, 3rd output gear wheels 43 are by transmission of power to the second leading screw 31, rotate to make the second leading screw 31, now the second leading screw 31 can drive the second screw 32 to move right, namely the first screw 22 and the second screw 32 synchronously move right, such first connecting rod 23 and second connecting rod 33 synchronously just can drive steering column drive spindle 1 to move right to right translation.
If actuator 5 such as motor contrarotation, then now the first screw 22 is to left movement, and the second screw 32, also to left movement, makes first connecting rod 23 and second connecting rod 33 drive steering column drive spindle 1 to be moved to the left.
In brief, engagement state is at first clutch 61, and second clutch 62 is when being in off-state, by the forward and reverse of actuator 5 such as motor, the first screw 22 can be realized synchronous with the second screw 32 to left movement or synchronously move right, make first connecting rod 23 and second connecting rod 33 drive steering column drive spindle 1 to move to the left or to the right, and then realize stretching of the steering column 200 that is connected with steering column drive spindle 1 and steering handwheel.
According to the steering column adjusting device 100 of the embodiment of the present invention, compare traditional double motor four-way regulating mechanism, not only structure is simple, be easy to realize, and the four-way adopting an actuator 5 such as motor just can realize steering handwheel regulates (namely tilt and stretch), reduce the holistic cost of steering column adjusting device 100, there is good practicality, can be widely used in the steering swivel system of existing vehicle.
According to one embodiment of present invention, steering column adjusting device 100 also comprises compound planet gear 7, actuator 5 is connected with the 3rd output gear wheels 43 with the first output gear wheels 41 by this compound planet gear 7, and wherein first clutch 61 is located between compound planet gear 7 and the 3rd output gear wheels 43.
With reference to shown in Fig. 2, particularly, this compound planet gear 7 can adopt or akin structure identical with the gear differential mechanism of vehicle such as automobile, such as this compound planet gear 7 can comprise compensating-gear shaft 71, be located at the planetary wheel 72 on compensating-gear shaft 71, 73 and with this planetary wheel 72, 73 engage and are positioned at planetary wheel 72, the finishing bevel gear cuter 74 of 73 both sides, 75, wherein the finishing bevel gear cuter 74 of side can be connected with the first output gear wheels 41, the finishing bevel gear cuter 75 of opposite side is connected with first clutch 61 by transmitter shaft 81, the output shaft of actuator 5 such as motor can be connected with compensating-gear shaft 71.
By arranging this compound planet gear 7, the first output gear wheels 41 and the 3rd output gear wheels 43 can be given by the power distribution of actuator 5, namely achieving the power distribution of actuator 5.
Need to illustrate a bit; in superincumbent description; comprising compensating-gear shaft 71, planetary wheel 72,73 and finishing bevel gear cuter 74,75 for compound planet gear 7 is only for exemplary purposes; can not be interpreted as one restriction of the present invention; can realize for other compound planet gear 7 distributing actuator 5 power, all fall within protection scope of the present invention.
According to one embodiment of present invention, steering column adjusting device 100 also to comprise on the transmitter shaft 81 that is located between compound planet gear 7 and first clutch 61, for the lockable mechanism 8 of locking transmitter shaft 81.In other words, transmitter shaft 81 is connected with between compound planet gear 7 and first clutch 61, for transmitting the power of actuator 5, lockable mechanism 8 can be close to this transmitter shaft 81 and to arrange and for locking or discharge this transmitter shaft 81, namely this lockable mechanism 8 is for braking this transmitter shaft 81.Alternatively, this lockable mechanism 8 can be drg.
By arranging lockable mechanism 8, when regulating the height of steering column drive spindle 1, because first clutch 61 is in off-state, therefore in order to avoid transmitter shaft 81 idle running causes the waste of energy, by lockable mechanism 8 locking transmitter shaft 81, make the power of actuator 5 all can pass to the first leading screw 21 by the first output gear wheels 41, the energy consumption of this steering column adjusting device 100 can be reduced so to a certain extent, avoid waste energy as electric energy.
