The utility model proposes a kind of door body driving device, suitable for air conditioner, wherein, which is used to drive
The dynamic door body at air conditioner wind outlet, makes door body be moved relative to air outlet, and air outlet is opened or closed to realize.
In one embodiment of the utility model, referring to figs. 1 to Fig. 3, the door body driving device 1, for air conditioner, the door
Body drive 1 includes being provided with door body driving mechanism 10b, the door body driving mechanism on base a 10a, the base 10a
10b includes：
Motor 110 and the gear set 130 driven by the motor 110, are mounted on the base 10a；
Rack 120, is slidably connected with the base 10a, and the rack 120 is engaged with the gear set 130；
Magnetic part 140, is fixedly arranged on the rack 120, and extends along the motion track direction of the rack 120, described
Direction is extended along on magnetic part 140 to be equipped with the multiple N poles magnetic pole 141 and multiple S poles magnetic pole 142 being arranged alternately successively；
Hall detection components 150, are fixedly arranged on the base 10a, and the Hall detection components 150 are towards the magnetic stripe
Set, so that the shift position that the Hall detection components 150 correspond to the rack 120 exports corresponding level pulse signal；
And
Controller, is connected with the motor 110 and the Hall detection components 150 respectively, and the controller is used to receive
The level pulse signal, and control the motor 110 to stop operating according to the level pulse signal.
Specifically, in air conditioner, air conditioner includes air conditioner main body and door body, and air outlet, bottom are offered in air conditioner main body
Seat 10a is fixedly installed in air conditioner main body, and rack 120 is connected with door body, when 110 drive rack 120 of motor moves, door body
It is driven therewith, and then opens or closes air outlet.In order to realize the closed-loop control to motor 110 so that door body is being closed out
Stop motor 110 when running into foreign matter during air port to run, in the present embodiment, magnetic part 140 is arranged on rack 120, and
Magnetic part 140 extends along the motion track direction of the rack 120, for example, when rack 120 is spur rack 120, magnetic part
140 linearly settings；When rack 120 is arc-shaped rack 120,140 arc-shaped setting of magnetic part.In this way, work as 120 phase of rack
When being moved to base 10a, the motion track of the motion track and rack 120 of magnetic part 140 is consistent.It is fixed on base 10a
Hall detection components 150 are installed, the sensing side magnetropism part 140 of Hall detection components 150 is set, with reference to Fig. 4, magnetic part
Direction is extended along on 140 and has been arranged alternately multiple N poles magnetic pole 141 and multiple S poles magnetic pole 142 successively, when rack 120 moves
When, Hall detection components 150 sense the movement of magnetic part 140, and then should according to the shift position of magnetic part 140, the output phase
Level signal.For example, when the N poles magnetic pole 141 in 150 face magnetic part 140 of Hall detection components, Hall detection components
150 are subject to magnetic part 140N pole fields to act on, and export high level pulse signal, when rack 120 drives magnetic part 140 to move,
Hall detection components 150 are subject to the magnetic field of magnetic part 140 to be changed into S pole fields from N pole fields, then export low level pulse signal,
In this way, in 120 moving process of rack, Hall detection components 150 export the low and high level pulse signal of continuous interval variation,
During door body closes air outlet, when running into barrier, door body is blocked by barrier, at this time 150 face of Hall detection components
A certain N poles magnetic pole 141 or S poles magnetic pole 142 on magnetic part 140, it is corresponding at this time to export high level pulse signal or low level arteries and veins
Rush signal.
That is, N poles magnetic pole 141 and S poles magnetic pole 142 are arranged at intervals with magnetic part 140, when rack 120 drives magnetic
Property part 140 move when, N poles magnetic pole 141 and S poles magnetic pole 142 are alternately across Hall detection components 150, Hall detection components 150
Corresponding level pulse signal is exported according to the field pole change of sensing.
Controller receives the level pulse signal of the output of Hall detection components 150, and by received level pulse signal
Duration compared with preset duration, when duration and the preset duration of same level pulse signal exceed preset duration,
Then controller judges that door body during air outlet is closed, runs into barrier, and at this time, controller control motor 110 stops operating,
The driving source of door body is cut off, and then prevents door body from constantly clamping barrier, causes 110 load excessive of motor to cause the electricity of motor 110
Gas component wear, OR gate body mechanical mechanism compression damage or barrier receive door body clamping and damage.In this way, it can carry
Security performance of the high air conditioner when door body closes air outlet, the security risk for avoiding user's limbs from being crushed by door body.Wherein, should
Controller can be made of the circuit of the one kind such as acquisition circuit, comparison circuit, amplifying circuit, control circuit, and then realize control
The various functions of device.
It should be noted that Hall detection components 150 are subject to the magnetic fields of magnetic part 140, and produce corresponding level
Pulse signal, the type of the level pulse signal are related with the type of the Hall sensor in Hall detection components 150.In other
In embodiment, when Hall detection components 150 are subject to the N pole fields of magnetic part 140, exportable low level pulse signal；Hall
When detection components 150 are subject to the S pole fields of magnetic part 140, then low level pulse signal is exported.Hall detection components 150 are usual
Set close to magnetic part 140, but both are not in contact with each other again, Hall detection components 150 are in the magnetic field induction model of magnetic part 140
In enclosing.In order to ensure that Hall detection components 150 and magnetic part 140 have good magnetic field induction effect, Hall detection
Component 150 and the spacing distance of magnetic part 140 are preferably 0.2 millimeter to 1 millimeter.
Technical solutions of the utility model are set suddenly by using magnetic part 140 is set on rack 120 on base 10a
That detection components 150, when the door body of air conditioner closes air outlet, rack 120 drives magnetic part 140 to move, magnetic part 140
N poles magnetic pole 141 and S poles magnetic pole 142 are alternately across Hall detection components 150, and Hall detection components 150 are according to the magnetic field magnetic of sensing
Pole change exports corresponding level pulse signal, and controller receives the level pulse signal, and more same level pulse signal
Duration and preset duration, and then judge whether door body runs into barrier, when door body runs into barrier, control motor
110 stop operating, and cut off the driving source of door body.In this way, can prevent door body from constantly clamping barrier, motor 110 is caused to load
It is big to cause the damage of 110 electrical equipment of motor, OR gate body mechanical mechanism compression damage or barrier to receive door body clamping and occur
Damage；And then air conditioner is avoided when door body closes air outlet, the security risk that user's limbs are crushed by door body, effectively carries
The high security performance of air conditioner.
Further, in the present embodiment, the development length of magnetic part 140 is greater than or equal to the motion track of rack 120
Length, so, it is ensured that length of the magnetic part 140 by Hall detection components 150 and the motion track length one of rack 120
The defects of causing, avoiding magnetic part 140 too short and cause Hall detection components 150 to sense failure.
