Detailed description of the invention
Please first consult Fig. 1 to Fig. 3, electronic type inner and outer pipes adjusting mechanism 10 of the present utility model includes pipe 30, regulating valve 40, motor 50, control unit 60 in an outer tube 20, and a sensing cell 70, outer tube 20 wherein and interior pipe 30 are described for seat pipe and seat bar respectively at this.
The top of interior pipe 30 is assembled with for a seat cushion (not shown), and the bottom of interior pipe 30 is inserted in outer tube 20 from the top of outer tube 20, and can along the axially bottom offset of outer tube 20.
Regulating valve 40 has valve seat 42 and a piston rod 44.Valve seat 42 is fixed in outer tube 20; Piston rod 44 can be axially movably arranged in valve seat 42 and have one be positioned at pipe 30 by supporting end 46.Thus, when the oil circuit state being subject to switch when being subject to the ejection of external force to end 46 in valve seat 42 of piston rod 44.
Motor 50 to be fixed in interior pipe 30 and to have an axle drive shaft 52, in order to provide power resources.
Control unit 60 has permanent seat 61, force-applying piece 62, and a prepressing elastic 63.Permanent seat 61 to be fixed in interior pipe 30 and the lower shaft hole 614, two with upper shaft hole 612, coaxial communication upper shaft hole 612 relatively radial communication in the guide groove 616 of upper shaft hole 612, and one radial communication in the mounting groove 618 of lower shaft hole 614, lower shaft hole 61 wherein by the piston rod 44 of regulating valve 40 by support end 46 wear.Force-applying piece 62 has a little axle portion 622, one macro-axis portion 624, and two relative radial lugs 626, macro-axis portion 624 connect little axle portion 622 and and form a terrace 64 between little axle portion 622, the outer peripheral face of radial lugs 626 from macro-axis portion 624 protrudes out outward and is embedded in the guide groove 616 of permanent seat 61, in addition, force-applying piece 62 has magnet fixed orifice 65 and a screw 66, magnet fixed orifice 65 radial lugs 626 located therein, screw 66 from childhood axle portion 622 extends to the screw 66 in macro-axis portion 624, make force-applying piece 62 can be located at the axle drive shaft 52 of motor 50 by screw 66 spiral shell, thus, force-applying piece 62 just can by the driving of the axle drive shaft 52 of motor 50 along guide groove 616 upper and lower displacement of permanent seat, prepressing elastic 63 is sheathed on the little axle portion 622 of force-applying piece 62, and the two ends bottom face of contact motor 50 and the terrace 64 of force-applying piece 62 respectively of prepressing elastic 63, the axle drive shaft 52 pairs of force-applying pieces 62 in order to servo-motor 50 provide thrust.In addition, the driving force of axle drive shaft 52 pairs of force-applying pieces 62 of motor 50 adds that elasticity recovery part power that prepressing elastic 63 pairs of force-applying pieces 62 discharge can be greater than the dumping force of the piston rod 44 of regulating valve 40.
Sensing cell 70 has Hall element 72 and a magnet 74.Be electrically connected a controller (not shown) in the mounting groove 618 that Hall element 72 is installed on permanent seat 61, magnet 74 is fixed in the magnet fixed orifice 65 of force-applying piece 62, makes magnet 74 can be mutually corresponding or stagger with Hall element 72 by moving axially of force-applying piece 62.
When the height of interior pipe 30 will be downgraded, as shown in Figures 3 to 6, first starter motor 50, the axle drive shaft 52 of motor 50 can drive force-applying piece 62 start to compress the piston rod 44 of regulating valve 40 by supporting end 46, in the process that force-applying piece 62 moves down, prepressing elastic 63 can discharge elasticity strength to force-applying piece 62 simultaneously, driving force due to axle drive shaft 52 pairs of force-applying pieces 62 of motor 50 adds that elasticity recovery part power that prepressing elastic 63 pairs of force-applying pieces 62 discharge can be greater than the dumping force of the piston rod 44 of regulating valve 40, so force-applying piece 62 can promote piston rod 44 smoothly present opening state to force the oil circuit in valve seat 42, now can start the height downgrading interior pipe 30.Height once force-applying piece 62 drops to allows magnet 74 correspond to Hall element 72, and Hall element 72 can transmit a sensing signal at once to controller, makes controller control motor 50 power-off further again, allows interior pipe 30 remain on an extreme lower position.
On the other hand, when the height of interior pipe 30 will be increased, first starter motor 50, make the axle drive shaft 52 of motor 50 drive force-applying piece 62 up movement remove the pressure to piston rod 44, at one time, the elasticity recovery part (not shown) be arranged in valve seat 42 can up promote piston rod 44 and force the oil circuit in valve seat 42 to present closed condition, when the height of force-applying piece 62 rise to allow magnet 74 stagger in Hall element 72 time, Hall element 72 can transmit another sensing signal at once to controller, controller is made to control motor 50 power-off, interior pipe 30 is allowed to remain on an extreme higher position.
It should be added that at this, technical characteristic of the present utility model is not limited to the collocation of applying present pipe and seat bar, also can be applicable to the combination (as shown in Figure 7) of front fork inner pipe and front fork outer tube, even also can be applied in shock-absorbing back vent, no matter but be applied in shock-proof front-fork assembly or shock-absorbing back vent, because thin portion structure is identical with operating mode and previous embodiment, in order to save space, repeat no more in this appearance.
In sum, the driving force that electronic type inner and outer pipes adjusting mechanism 10 of the present utility model is provided by the axle drive shaft 52 of motor 50 and the elasticity strength that prepressing elastic 63 discharges, force-applying piece 62 is allowed to have enough strength can promote the piston rod 44 of regulating valve 40 to switch the oil circuit state of regulating valve 40, to reach the effect of pipe 30 height in adjustment, so operate not only quick side's wall, and can alleviate the load of motor 50 and reach the effect increased the service life.
