As an example of a specific implementation manner, in the driving main unit of the electric lifting clothes hanger, the signal acquisition unit includes a first magnetic body fixed on the worm and a second magnetic body fixed on any one of the winding wheels, the first magnetic body is disposed corresponding to a first hall sensing element fixedly disposed, the second magnetic body is disposed corresponding to a second hall sensing element fixedly disposed, and the first hall sensing element and the second hall sensing element are respectively connected to the electric control mechanism.

In order to further improve the control precision of the driving host machine on the driving motor, in the driving host machine of the electric lifting clothes hanger, the electric control mechanism is also connected with an upper travel touch switch and a lower travel touch switch, the upper travel touch switch and the lower travel touch switch are both positioned on the periphery of the trigger turntable, an upper limit stop block and a lower limit stop block are arranged on the outer edge of the trigger turntable, the winding wheel is connected with the trigger turntable through a gear speed reducing structure and can drive the trigger turntable to rotate, and after the trigger turntable rotates for a set angle, the upper limit stop block and the lower limit stop block can respectively contact with the upper travel touch switch and the lower travel touch switch to respectively generate an upper travel signal and a lower travel signal.

Under the action of the gear speed reducing structure, the trigger turntable only rotates one circle or less in each working process; when the number of turns of the winding wheel reaches a preset value (the trigger turntable rotates by a preset angle), an upper limit stop block on the outer edge of the trigger turntable just contacts with the upper travel touch switch to generate an upper travel signal; or the lower limit stop block is just contacted with the lower stroke touch switch to generate a lower stroke signal; and after the electric control mechanism receives the upper stroke signal or the lower stroke signal, the electric control mechanism commands the driving motor to stop working.

In the above driving main machine of the electric lifting clothes hanger, the gear reduction structure includes a first pinion rotating coaxially with the winding wheel, a gear ring arranged on the trigger turntable, and at least one duplicate gear rotatably connected to the machine box, the duplicate gear includes a bull gear and a second pinion coaxially arranged, the bull gear is in meshing transmission with the first pinion, and the second pinion is in meshing transmission with the gear ring.

In the driving main machine of the electric lifting clothes hanger, a stroke setting structure capable of adjusting the position of the upper limit stop and/or the lower limit stop on the circumference of the triggering rotary table so as to change the upper stroke and/or the lower stroke is arranged between the triggering rotary table and the upper limit stop and/or the lower limit stop. The position of the upper limit stop block and/or the lower limit stop block on the circumference of the trigger turntable can be adjusted by utilizing the stroke setting structure, so that the contact time of the upper limit stop block and the upper stroke touch switch and/or the contact time of the lower limit stop block and the lower stroke touch switch are adjusted, and the stroke of the lifting pulling wire is conveniently adjusted in a user-defined mode.

In the driving host of the electric lifting clothes hanger, the stroke setting structure comprises an adjusting block provided with an upper limit stop, the adjusting block is provided with at least one first positioning hole, the outer edge of the trigger turntable is provided with a plurality of second positioning holes distributed in the circumferential direction, and the first positioning hole and the second positioning hole are fixedly connected through a fastener; the lower limit stop block is connected with the trigger turntable into a whole.

Of course, the lower limit stop block can also be arranged to move along the outer edge of the trigger turntable, and the upper limit stop block can also be arranged to be connected with the trigger turntable into a whole; or the upper limit stop block and the lower limit stop block are both arranged to be movable along the outer edge of the trigger turntable.

Therefore, the user can conveniently and quickly adjust the position of the adjusting block according to the specific application scene.

The signal acquisition unit, the upper travel touch switch and the lower travel touch switch can only control the travel end point of the lifting traction line, but when the lifting traction line reaches the upper and lower limit positions, the lifting traction line loaded with the clothes hanger can always pull the winding wheel, so that a large load is caused to the winding wheel and the driving motor; and when the lifting pulling wire is loosened and separated suddenly), the signal acquisition unit, the upper travel touch switch and the lower travel touch switch cannot send signals to the electric control mechanism in time to stop the motor, and the lifting pulling wire is difficult to grasp timely, so that the clothes hanger is in danger of falling suddenly.

Therefore, in the driving main machine of the electric lifting clothes hanger, the machine box is provided with two pulling line inlets and outlets which respectively correspond to the two winding wheels, and each pulling line inlet and outlet is respectively provided with an auxiliary line control mechanism.

In the above-mentioned driving main machine of the electric lifting clothes hanger, the auxiliary line control mechanism comprises a swinging member, one end of the swinging piece is hinged at a hinged point at one side of the lifting pulling line, one side of the swinging piece is provided with a lateral touch switch, the swinging piece is connected with an elastic structure which enables the swinging piece to have a swinging trend towards the lateral touch switch, the lifting traction wire penetrates through the swinging piece and exerts acting force for counteracting the swinging trend to the swinging piece when the lifting traction wire is in a normal state of tension, and when the lifting pulling wire is lower than the normal tightening state, the swinging piece swings towards the lateral touch switch and contacts with the lateral touch switch to generate a control signal, the lateral touch switch is electrically connected with the electric control mechanism, and when the electric control mechanism receives a control signal generated by the lateral touch switch, the electric control mechanism controls the driving motor to stop working.

In the auxiliary line control mechanism, the swinging piece and the lateral touch switch are oppositely arranged, and the swinging piece has a tendency of swinging towards the lateral touch switch under the action of the elastic structure; however, since the lifting pulling wire is arranged on the swinging member in a penetrating manner, when the lifting pulling wire works normally and is in a tensed state, the lifting pulling wire can generate lateral pressure on the swinging member, the lateral pressure can counteract the swinging trend of the swinging member to the lateral touch switch, and the lateral touch switch is not triggered at the moment. When the lifting pulling line reaches the limit position and stops lifting or the line end is loosened (namely, the side pressure is lower than the normal state in a tightened state), the side pressure exerted on the swinging piece by the lifting pulling line disappears, the swinging piece swings towards the side touch switch under the action of the elastic structure, and the side touch switch is triggered; after receiving a control signal sent by the lateral touch switch, the electric control mechanism immediately commands the driving motor to stop working and stops retracting the lifting pull wire; meanwhile, the swinging of the swinging piece can also clamp the lifting pulling line to prevent the lifting pulling line from lifting.

The auxiliary wire control mechanism can not only assist the upper limit switch and the lower limit switch to stop the driving motor in time when the lifting traction wire reaches the upper limit position and the lower limit position, but also clamp the lifting traction wire, and reduce the load pressure of the reel and the driving motor to a certain extent; and when the lifting pulling line is accidentally loosened, the driving motor can be stopped in time and the lifting pulling line can be clamped and positioned, so that the clothes hanger is prevented from falling suddenly.

In the driving main machine of the electric lifting clothes hanger, the swinging piece is hinged to the machine box, the hinged point is located on one side of the pulling line access, and the lateral touch switch is fixed on the machine box and located on the other side of the pulling line access.

In the driving host of the electric lifting clothes hanger, the elastic structure comprises a torsion spring arranged at a hinge point; or the elastic structure comprises a tension spring, one end of the tension spring is connected with one end of the swinging piece, and the other end of the tension spring is connected with the machine box.

In the driving host of the electric lifting clothes hanger, the swinging piece is provided with a wire passing groove, and the lifting pulling wire penetrates through the wire passing groove; a rolling body is arranged on one side of the wire passing groove, when the lifting traction wire is in a normal state of tension, the lifting traction wire passes through the wire passing groove in a suspended mode and is in rolling contact with the rolling body, and when the swinging piece swings to be in contact with the lateral touch control switch, the lifting traction wire is in contact with the wall of the wire passing groove; the wire passing groove is in a strip shape, and the extension direction of the wire passing groove is consistent with the width direction of the pull line inlet and outlet; the rolling body is a cylinder and is arranged in parallel with the wire passing groove.

When the lifting traction line normally works in a normal state and is in a normally tightened state, the lifting traction line only contacts with the rolling body in a rolling manner, so that the lifting traction line can apply an acting force for offsetting the swinging trend of the swinging piece to the swinging piece, the lifting traction line can be protected, and the phenomenon that the service life of the lifting traction line is shortened due to excessive friction is avoided. When the lifting pulling line is lower than the normal state in a tightening state, the swinging of the swinging piece can lead the lifting pulling line to be contacted with the groove wall of the wire passing groove, thereby realizing the clamping and positioning of the lifting pulling line.

The strip-shaped wire passing groove provides enough space for normal lifting of the lifting pulling and pulling wire on one hand, and on the other hand, the swinging distance of the swinging piece required for clamping the lifting pulling and pulling wire is shortened, so that once the lifting pulling and pulling wire is abnormal in work, the swinging piece can quickly respond to the clamping of the lifting pulling and pulling wire.

The rolling bodies and the wire passing grooves are arranged in parallel, so that enough space can be further provided for normal lifting of the lifting pulling wire.

When the lifting pulling wire is clamped and positioned, the lifting pulling wire is in a folded angle state at the swinging part and is respectively attached to the surface of the rolling body and the wall of the wire passing groove. However, the groove wall of the wire passing groove has edges and corners, so that the lifting pulling wire is worn. Therefore, in the driving main machine of the electric lifting clothes hanger, the middle part of one side of the wire passing groove close to the rolling body is provided with a concave area, and the lifting pulling wire is positioned in the concave area when the swinging piece swings to be in contact with the lateral touch switch. The sunken area enables the lifting pulling line not to contact with the edges and corners between the walls when the lifting pulling line contacts with the wire passing groove, and the lifting pulling line is prevented from being abraded.

When at least one of the number of turns of the worm 21 and the number of turns of the winding wheel 3 reaches a preset value, the signal acquisition unit 6 sends a control signal to the electric control mechanism, and the electric control mechanism commands the driving motor 2 to stop working. The power shaft of the driving motor 2 and the winding wheel 3 are in linkage relation, the power shaft and the winding wheel rotate synchronously and are directly associated with the driving motor 2, so that signals acquired by the signal acquisition unit 6 can be fed back to the electric control mechanism in real time, and the electric control mechanism can also control the driving motor 2 timely and quickly.

Besides the signal acquisition unit 6 is adopted to control the driving motor 2, the braking mechanism 4 is also arranged as an auxiliary in the embodiment, so as to improve the control precision of the electric control mechanism to the driving motor 2.

As shown in fig. 2 and 3, the wire passage groove 51a is elongated and extends in the direction corresponding to the width direction of the pull lead doorway 15. The length of the wire passing groove 51a is equivalent to the width of the pulling line access 15, so that enough space can be provided for the normal retraction of the lifting pulling line 100; the width of the wire passing groove 51a is narrow, and when the swinging piece 51 swings, the lifting traction line 100 can be driven to deviate from the original running track only by swinging a small distance, so that the lifting traction line 100 is clamped and positioned.

As shown in fig. 2, the swinging member 51 is provided with an elastic structure 54 that makes the swinging member 51 swing toward the lateral touch switch 53, however, since the lifting and lowering pulling wire 100 is inserted into the swinging member 51, when the lifting and lowering pulling wire 100 is working normally and in a normal state of tension, the lifting and lowering pulling wire 100 generates a lateral pressure on the swinging member 51, the lateral pressure can counteract the swinging tendency of the swinging member 51 toward the lateral touch switch 53, and the lateral touch switch 53 is not triggered. When the lifting pulling line 100 reaches the limit position to stop lifting or the line end is loosened (i.e. lower than the normal state of tension), the lateral pressure exerted on the swinging member 51 by the lifting pulling line 100 disappears, the swinging member 51 swings towards the lateral touch switch 53 under the action of the elastic structure 54, and the lateral touch switch 53 is triggered; after receiving a control signal sent by the touch switch, the electric control mechanism immediately commands the driving motor 2 to stop working and stops retracting the lifting pull wire 100; meanwhile, the swinging of the swinging piece 51 can also clamp the lifting and pulling wire 100, so as to prevent the lifting and pulling wire 100 from lifting.

The lateral touch switch 53 selected in this embodiment is a microswitch, which has high sensitivity and can respond quickly to generate a control signal.

The elastic structure 54 used in this embodiment includes a tension spring 54a, one end of the tension spring 54a is connected to one end of the swing member 51, and the other end is connected to the box body 11.

As shown in fig. 5 and as seen in fig. 2 and 3, a cylindrical rolling body 55 is rotatably mounted on the swinging member 51 on the side facing the pull lead entrance 15, and the rolling body 55 is disposed in parallel with the wire passage groove 51 a. When the lifting traction line 100 is in a normal tightening state, the lifting traction line 100 is suspended to pass through the thread groove 51a and is in rolling contact with the rolling body 55, so that the lifting traction line 100 can apply an acting force for counteracting the swinging trend of the swinging piece 51 to the swinging piece 51, the lifting traction line 100 can be protected, and the service life is prevented from being shortened due to excessive friction of the lifting traction line 100; when the swinging member 51 swings to contact with the lateral touch switch 53, the lifting pulling wire 100 contacts with the wall of the wire passing groove 51a, so as to clamp and position the lifting pulling wire 100.

When the lifting and pulling wire 100 is clamped and positioned, the lifting and pulling wire 100 is in a folded angle state at the swinging piece 51, and the lifting and pulling wire 100 is respectively attached to the surface of the rolling body 55 and the groove wall of the wire passing groove 51 a. However, the lifting and pulling wire 100 is worn due to the angular edges between the groove walls of the wire passing groove 51 a. Therefore, as shown in fig. 2 and fig. 3, in the present embodiment, a recessed area 51b is provided in a middle portion of the wire passing groove 51a near the rolling body 55, and when the swinging member 51 swings to contact with the lateral touch switch 53, the lifting pulling wire 100 is located in the recessed area 51 b. The recessed area 51b prevents the lifting pulling wire 100 from contacting the corner between the walls when the lifting pulling wire 100 contacts the wire passing groove 51a, thereby preventing the lifting pulling wire 100 from being worn.

The operating principle of the driving main machine of the electric lifting clothes hanger in the embodiment is as follows:

when the lifting traction line 100 needs to be put down, the driving motor 2 is started, the driving motor 2 drives the winding wheel 3 to rotate through the worm 21, the lifting traction line 100 is released, and the lifting traction line 100 goes down after passing through the traction line access 15 and the line passing groove 51 a; in the process, the signal acquisition unit 6 acquires a rotation number signal of the worm 21 and a rotation number signal of the winding wheel 3, and the trigger turntable 44 is driven by the winding wheel 3 to slowly rotate; when the number of turns of the worm 21 and the number of turns of the winding wheel 3 detected by the signal acquisition unit 6 are equal to the preset values, the lower limit stop 44b also contacts the lower travel touch switch 42, and the electric control mechanism receives control signals sent by the signal acquisition unit 6 and the lower travel touch switch 42 and orders the driving motor 2 to stop working.

When the lifting traction line 100 needs to be retracted, the driving motor 2 is started again, the worm 21 drives the winding wheel 3 to rotate reversely, the lifting traction line 100 is wound up, and the lifting traction line 100 goes upwards after penetrating through the traction line inlet/outlet 15 and the line passing groove 51 a; in the process, the signal acquisition unit 6 acquires a rotation number signal of the worm 21 and a rotation number signal of the winding wheel 3, and the trigger turntable 44 is driven by the winding wheel 3 to slowly rotate; when the number of turns of the worm 21 and the number of turns of the winding wheel 3 detected by the signal acquisition unit 6 are equal to the preset values, the upper limit stop 44a also contacts the upper travel touch switch 41, and the electric control mechanism receives control signals sent by the signal acquisition unit 6 and the upper travel touch switch 41 and orders the driving motor 2 to stop working.

In the whole lowering or retracting process of the lifting traction line 100, the lifting traction line 100 is in a normal state and is in a tight state, and the acting force exerted on the swinging piece 51 by the lifting traction line 100 enables the swinging piece 51 not to swing towards the lateral touch switch 53; when the lifting pulling wire 100 reaches the lower limit position or the upper limit position, the acting force exerted on the swinging piece 51 by the lifting pulling wire 100 disappears, the swinging piece 51 swings towards the lateral touch switch 53 under the driving of the tension spring 54a, when the swinging piece 51 contacts the touch point 53a of the lateral touch switch 53, the lateral touch switch 53 sends a control signal to the electric control mechanism, and after the electric control mechanism receives the control signal sent by the touch switch, the electric control mechanism immediately commands the driving motor 2 to stop working, and stops putting down or taking up the lifting pulling wire 100; meanwhile, after the swinging piece 51 swings in place, the lifting traction line 100 is also clamped, so that the lifting traction line 100 is prevented from lifting.

In the process of lowering the lifting and pulling line 100, if the lower part of the clothes hanger is blocked, and in the process of lowering or retracting the lifting and pulling line 100, if the end part of the lifting and pulling line 100 is loosened from the winding wheel 33 and rapidly lowered, the lifting and pulling line 100 can not keep in a tight state; at this time, the acting force exerted on the swinging member 51 by the lifting pulling wire 100 also disappears, the swinging member 51 swings towards the lateral touch switch 53 under the driving of the tension spring 54a, when the swinging member 51 contacts the touch point 53a of the lateral touch switch 53, the lateral touch switch 53 sends a control signal to the electric control mechanism, and the electric control mechanism immediately orders the driving motor 2 to stop working after receiving the control signal sent by the touch switch, and stops lowering or retracting the lifting pulling wire 100; meanwhile, after the swinging piece 51 swings in place, the lifting traction line 100 is also clamped, so that the lifting traction line 100 is prevented from continuously lifting.
