Solution structure schematic diagram.
The door lifter includes：Rotary electric machine 10, first gear 20, upper holder 30, second gear 40, rotary shaft 50,
Lifting magnet 60, clutch discs 70, the 3rd gear 80, the 4th gear 90, main shaft 11 and lower fixed frame 12.
The first gear 20 is arranged on the motor shaft 101 of the rotary electric machine 10, and the second gear 40 is arranged on
On the lifting magnet 60, the lifting magnet 60 is arranged on the end face of one end of the clutch discs 70, institute's clutch discs 70 it is another
The face at end is provided with the 3rd gear 80, and the second gear 40, lifting magnet 60, the gear 80 of clutch discs 70 and the 3rd pass through institute respectively
State rotary shaft 50 to be arranged between fixed frame 30 and lower fixed frame 12, the 4th gear 90 is arranged on the main shaft 11
On, the main shaft 11 is arranged between fixed frame 30 and lower fixed frame 12.
The motor shaft 101 drives the first gear 20 to rotate, and the first gear 20 drives the second gear 40
It is axis rotation with the rotary shaft 50, the second gear 40 drives the lifting magnet 60 to turn with the rotary shaft 50 for axle center
Dynamic, the lifting magnet 60 drives the clutch discs 70 with the rotary shaft 50 for axis rotation under magneticaction, the clutch
Disk 70 drives the 3rd gear 80 with the rotary shaft 50 for axis rotation, and the 3rd gear 80 drives the 4th gear
90 rotate, and the 4th gear 90 drives the main shaft 11 to rotate.
More specifically, because motor 10 can be rotated continuously when rotating, and motor 10 does not detect the electricity
Whether broken down on arbor 101, some accidents often occur when applying to door lifter in motor 10 on the main shaft of door lifter
Situation, as pedestrian blocks main shaft.Now, motor 10 drives the main shaft 11 to be rotated further by gear, and main shaft due to
Fortuitous event can not rotate, and by Maximum Power Output, prolonged maximum power output will cause described motor 10 now
Motor 10 is burnt out.
By the lifting magnet 60 and the clutch discs 70 respectively by the He of motor 10 in the utility model embodiment
Main shaft 11 is separated so that is connected between the motor 10 and main shaft 11 not over direct geared.With this, the timely master
When occurring big resistance on axle 11, because the magnetic force between the lifting magnet 60 and the clutch discs 70 is certain, master
Resistance on axle 11, which does not have, to be all transferred to 101 on the motor shaft, and the main shaft is due to when external force stops operating, the electricity
Machine 10 still can drive the lifting magnet 60 to be rotated further by the first gear 20 and second gear 40, described so as to protect
Motor.
On the other hand, because when external drag makes the main shaft 11 stop operating, the motor 10 continues to drive
The main shaft 11 is rotated further, so as to also protect the pedestrian for making the main shaft 11 stop operating or vehicle etc..
Preferably, in one embodiment of the present utility model, the lifting magnet 60 and clutch discs 70 are respectively circle
Shape.
Preferably, in one embodiment of the present utility model, the second gear 40 is more than the first gear 20,
So as to realize that the output of the rotating speed of the second gear 40 is slowed down.
Preferably, in one embodiment of the present utility model, the 4th gear 90 is more than the 3rd gear 80,
So as to realize that the output of the rotating speed of the 4th gear 90 is slowed down.
Alternatively, in one embodiment of the present utility model, set respectively on fixed frame 30 and lower fixed frame 12
There are the first groove 301 and the second groove 121, the both ends of the main shaft 11 are respectively equipped with the first retainer ring 111 and the second retainer ring
112, one end of the rotary shaft 50 is arranged in the first groove 301 of institute by first retainer ring 111, the rotary shaft 50
The other end be arranged on by second retainer ring 112 in second groove 121.
The utility model embodiment drives the lifting magnet 60 with described turn by the first gear 20, second gear 40
Moving axis 50 is axis rotation, and the lifting magnet 60 drives the clutch discs 70 with the rotary shaft 50 for axle center under magneticaction
Rotate, it is achieved thereby that clutch is applied on door lifter, by main shaft 11 and motor shaft 101 are passed through institute by the door lifter
State lifting magnet 60 and clutch discs 70 separated, though so as to institute's main shaft 11 when being obstructed by external force, the lifting magnet 60 with
The clutch that the clutch discs 70 form can be protected to the motor, avoid motor from burning out.
Further, since when external drag makes the main shaft 11 stop operating, the motor 10 continues described in drive
Main shaft 11 is rotated further, so as to also protect the pedestrian for making the main shaft 11 stop operating or vehicle etc..
The utility model embodiment uses clutch principle, and it is applied on door lifter, coordinates other such as infrared detection
Etc. means, solve door lifter when routine use process surprisingly occurs to equipment in itself and current personnel, effective guarantor of vehicle
Shield.
