In some embodiments, the resistance adjusting component 3 provides stronger friction resistance for the driving motor 2 when the motor stops rotating, namely the clothes hanger stops lifting, so that the self-locking requirement of the clothes hanger is met, and when the motor starts rotating, the contact area between the resistance adjusting component 3 and the shell 1 is reduced, so that the friction force to be overcome when the motor rotates is reduced, the starting resistance of the motor is reduced, and the resistance self-adjustment of the motor module is realized.
In some embodiments, a worm sleeve 32 sleeved on a motor shaft of the driving motor 2 is used for transmitting power, the end part of the worm sleeve 32 is matched with a friction bowl sleeve 31 in the resistance adjusting assembly 3, when the motor is started, the driving motor 2 drives the worm sleeve 32 to rotate, the worm sleeve 32 firstly drives a resistance adjusting sleeve 33 arranged in the friction bowl sleeve 31 to rotate, and when the resistance adjusting sleeve 33 synchronously rotates along with the worm sleeve 32, the friction bowl sleeve 31 synchronously rotates along with the resistance adjusting sleeve 33 due to the matching. The above transmission is generated because the self-locking force of the motor to the reel 10 is reduced after the motor moves from the middle of the reel 10 to one side, so that a new self-locking force needs to be added to meet the self-locking requirement of the laundry rack, namely, the end part of the motor shaft of the driving motor 2 is abutted, and the self-locking of the driving motor 2 is increased by the static friction force generated by the abutting of the part after the driving motor 2 is stopped.
Specifically, through the cooperation of resistance adjustment cover 33 and friction bowl cover 31, when the motor is stopping to start, resistance adjustment cover 33 is partly embedded in friction bowl cover 31, the outer terminal surface of resistance adjustment cover 33 and the outer terminal surface of friction bowl cover 31 back joint jointly is on casing 1, thereby increased the area of contact with casing 1, the self-locking force demand of motor has been satisfied, in addition, when driving motor 2 begins to rotate, wedge face cooperation between resistance adjustment cover 33 and the worm cover 32, make worm cover 32 can drive resistance adjustment cover 33 inwards (the direction of keeping away from the outer terminal surface of friction bowl cover 31) when rotating, thereby make resistance adjustment cover 33 not with casing 1 butt, the area of contact with casing 1 has been reduced, thereby the starting resistance of motor has been reduced.
In some embodiments, a return spring 333 is provided between the worm housing 32 and the resistance adjustment housing 33; when the motor starts to rotate, the return spring 333 is pressed under the back of the resistance adjusting sleeve 33, when the motor stops rotating, the return spring 333 restores the elastic deformation to push the resistance adjusting sleeve 33 to back, and the resistance adjusting sleeve 33 is returned to a state of abutting against the casing 1 at the beginning, so that the contact area with the casing 1 is restored.
In some embodiments, the outer end surface of the friction bowl sleeve 31 is uniformly provided with a plurality of insertion notches 311, the abutting portion 331 of the resistance adjusting sleeve 33 is installed in the insertion notches 311, the connecting portion 332 of the resistance adjusting sleeve 33 is located in the friction bowl sleeve 31, the outer side wall of the connecting portion 332 is obliquely arranged, that is, the overall shape of the connecting portion 332 is wedge-shaped, the inner side wall of the pushing protrusion 321 arranged on the worm sleeve 32 is obliquely arranged, that is, the overall shape of the pushing protrusion 321 is also wedge-shaped, the two forms a wedge-shaped surface matching relationship, and when the worm sleeve 32 rotates, the pushing protrusion 321 can push the connecting portion 332 to slide along the inclined surface thereof, so that the abutting portion 331 and the casing 1 are not abutted any more.
In some embodiments, the shape of the abutment 331 corresponds to the shape of the insertion notch 311; the size of the abutting portion 331 is smaller than the size of the insertion notch 311, so that the abutting portion 331 can slide smoothly in the insertion notch 311, and in particular, the abutting portion 331 cannot slide out of the insertion notch 311 completely, but only does not abut against the casing 1.
In some embodiments, the driving motor 2 and the reel 10 are driven by a transmission gear 11; the worm sleeve 32 is meshed with the transmission gear 11, so that the normal folding and unfolding use of the clothes hanger is realized.
Some embodiments also provide a working method of the resistance-adjustable motor module, which includes: the reel 10 in the motor module is driven to rotate by the driving motor 2; the starting resistance of the driving motor 2 is regulated by a resistance regulating assembly 3. The specific working method is described above and will not be repeated here.
In summary, according to the resistance-adjustable motor module and the working method thereof, the resistance adjusting component 3 is arranged between the driving motor 2 and the casing 1, so that stronger friction resistance is provided for the driving motor 2 when the motor stops rotating, namely, the clothes hanger stops lifting, the self-locking requirement of the clothes hanger is met, and when the motor starts rotating, the contact area between the resistance adjusting component 3 and the casing 1 is reduced, so that the friction force to be overcome when the motor rotates is reduced, the starting resistance of the motor is reduced, and the resistance self-adjustment of the motor module is realized.
