When mode side is mobile, the gear lever 11 can be respectively moved to P gear, R gear, N gear and D gear.
It is described when along manual mode side extending direction moving gear shift bar 11 when the gear lever 11 is at manual mode side
Gear lever 11 can switch between manual gear.
The gear lever 11 is located at the radial side of the cam 16.The manual mode side is set towards 16 direction of cam
It sets, the automatic mode side is arranged far from 16 direction of cam.On the gear lever 11 be equipped with for stopper section 18 against
Contact portion 17.When the gear lever 11 is transferred to manual mode side from automatic mode side, the contact portion 17 is therewith towards convex
The direction of wheel 16 is mobile.
The rotating electric machine 12 is mounted on supporter 10, and the rotating electric machine 12 passes through worm gear mechanism band moving cam
16 rotations.Worm screw 13 is fixed in the shaft of the rotating electric machine 12.The cam 16 is fixed on worm gear 14.
It is connected with installation axle 15, the worm gear 14 and cam 16 on the supporter 10 and passes through the installation axle 15 and the supporter
10 rotation connections.The rotating electric machine 12 drives worm screw 13 to rotate by shaft.The worm screw 13 can drive worm gear 14 when rotating
It is rotated with cam 16.
The cam 16 is the eccentric wheel of eccentric design.Stopper section 18 is equipped on the cam 16.The stopper section 18
It is arranged with the rotation center interval of the cam 16.When the rotating electric machine 12 is rotated with moving cam 16, the stopper section 18
Around rotation center rotation and position changes.The stopper section 18 has evacuation position and stop dog position.The cam
16 can only be parked in evacuation position and stop dog position respectively under the drive of rotating electric machine 12, and in evacuation position and stop dog position
Between switch.The rotating electric machine 12 drives stopper section 18 that can specifically be arranged as needed around the angle of rotation center rotation.
Magnet 22 is installed on the worm gear 14 or cam 16.It is equipped in the radial side of the magnet 22 for incuding
The Hall sensor 23 of magnet information, the Hall sensor 23 are connected electrically on circuit board 24.For example, the circuit board 24 is pacified
On supporter 10 or other component.When the worm gear 14 or cam 16 rotate, the magnet 22 is rotated with it, described
Hall sensor 23 passes through the Magnetic Field of induced magnet 22, detects the rotational angle of cam 16, Real-time Feedback stopper section 18
Current location.
With reference to Fig. 4 and Fig. 5, when the cam 16 is only parked in stop dog position, the stopper section 18 can be in automatic mold
The gear lever 11 of formula side carries out backstop, prevents the gear lever 11 from shifting from automatic mode side to manual mode side.
With reference to Fig. 6 and Fig. 7, when the cam 16 is only parked in evacuation position, the gear lever 11 can be in automatic mode side
It is shifted between manual mode side.The cam 16 does not generate interference backstop with the gear lever 11 for being located at automatic mode side, also not
Interference backstop is generated with the gear lever 11 for being located at manual mode side.
The difference of gear is presently according to the gear lever 11, the rotating electric machine 12 carries out corresponding actions.
When the gear lever 11 is located at the non-D gear in automatic gear, the rotating electric machine 12 drives stopper section 18 to move
It moves to stop dog position.The gear lever 11 cannot be shifted from automatic mode side to manual mode side.
When the gear lever 11 is located at the D gear of automatic mode side, the rotating electric machine 12 drives stopper section 18 mobile
To evacuation position.The gear lever 11 can be shifted from the D gear of automatic mode side to manual mode side, be operated manually.
When the gear lever 11 is located at manual mode side, the rotating electric machine 12 drives stopper section 18 to be moved to evacuation position
It sets.The gear lever 11 can be shifted from manual mode side to the D gear of automatic mode side.
The automatic parking button is arranged on the other component of the gear lever 11 or automobile.Institute is triggered in user
After stating automatic parking button, automobile brake parking, and the rotating electric machine 12 drives stopper section 18 to be moved to stop dog position.
When parking, if the gear lever 11 is currently located at manual mode side, user's parking presses the automatic parking and presses
After button, the rotating electric machine 12 drives stopper section 18 to be moved to stop dog position, and the stopper section 18 can be against the contact portion 17
And the gear lever 11 is pushed, so that the gear lever 11 is transferred to automatic mode side from manual mode side.It is described later to change
Bar 11 automatically resets to P gear.
When parking, if the gear lever 11 is currently located at automatic mode side, user's parking presses the automatic parking and presses
After button, the rotating electric machine 12 drives stopper section 18 to be moved to stop dog position, and the idle running of cam 16 does not drive gear lever 11 to move
It is dynamic.
In this way, when the gear lever 11 is located at manual mode side, if user, which is stopped, triggers the automatic parking button, institute
Automatic mode side can be returned to and then return to P gear by stating gear lever 11.The gear lever 11 after parking is prevented to be always positioned at manual mould
Formula side, automobile remain to be moved, and there are security risks.
In the embodiment, with reference to Fig. 8, the worm gear 14 and cam 16 can be wholely set.The worm gear 14 and 16 sets of cam
It is located in installation axle 15.There are many rotation connection modes between the worm gear 14 and cam 16 and the supporter 10.For example,
The installation axle 15 is fixedly connected on the supporter 10, and the worm gear 14 and cam 16 and the installation axle 15 rotation connect
It connects.In another example the installation axle 15 is rotatably connected on the supporter 10, the worm gear 14 and cam 16 and the installation axle
15 are fixedly connected.Certainly, the worm gear 14 and cam 16 can also be fixed by other connection types.For example, the magnet 22 is solid
Surely it is set on integral piece made of being wholely set as worm gear 14 and cam 16.
In the embodiment, the mountable guide way on the supporter 10, the guide part is arranged on the guide way.
The guide way can be made of the biggish material of rigidity, can reduce the damage to supporter 11.
Worm gear mechanism in the present embodiment also may alternatively be other gear drives.
Cam 16 in the present embodiment can also directly be driven by rotating electric machine 12 or other driving mechanisms.
Rotating electric machine 12 in the present embodiment also may alternatively be other driving mechanisms, can be according to selected driver
The type of structure is specifically arranged.
The above is only the utility model preferred embodiments, are not used to the limitation protection scope of the utility model, any
Modification, equivalent replacement or improvement within the spirit of the present invention etc. are all covered in the scope of the claims of the utility model.
