Description
Technical Field
The invention belongs to the technical field of electric clothes hangers, and particularly relates to a driving module for an electric clothes hanger.
Background
The electric clothes hanger is a common household appliance for solving the problem of indoor clothes airing.
The driving modules of the existing electric clothes hanger all adopt a mode that a driving mechanism drives a reel assembly to rotate so as to realize lifting of a clothes hanger, and a motor in the driving mechanism is arranged between two reels, such as a winding device for the electric clothes hanger and the electric clothes hanger with the patent number of CN 219238909U; however, in the current market, hidden/first-line-day electric clothes hangers are more and more mainstream, and the characteristics of the electric clothes hangers are that: the main machine housing is narrow, and in order to adapt to the electric clothes hanger, the motor of the driving module needs to be moved to one side from the middle of the two reels, so that the width of the driving module is reduced.
The common self-locking adopts worm and gear matching, and the worm and gear is usually made of high polymer materials such as polyimide, polyamide and the like.
As shown in the above patent, the self-locking function is realized by propping the rotating shaft of the motor against the damping fin, and the rotating shaft of the motor is arranged between the two reels; therefore, in order to drive the two reels to rotate, the worm two sides arranged on the rotating shaft of the motor are meshed with the worm wheels, so that the rotating shaft of the motor is stressed uniformly, the deformation force born by the rotating shaft is small, and the contact with the damping fin is not influenced by deformation.
However, when the motor is moved to the side edges of the two winding wheels, the worm on the rotating shaft of the motor can only be meshed with one turbine, so that the rotating shaft of the motor is stressed unevenly to generate slight deformation, and the repeated test shows that the slight deformation can damage the self-locking relationship of the worm and the worm when the load reaches 15 kg, and the self-locking capability is lost; when the lifting action stops, the worm and gear self-locking often cannot respond immediately, and the reel can rotate to a certain degree under the pulling force of the load.
Therefore, there is a need to design a driving module for an electric clothes hanger to solve the above problems.

As shown in fig. 3, the locking mechanism 2 is further provided with a hole member 24, and the damping fin 22 is arranged at the bottom of the hole member 24; the end of the worm shaft sleeve 21 extends into the hole piece 24, and the end face of the worm shaft sleeve is matched with the damping fin 22 at the bottom of the hole piece 24.
In the present embodiment, the reel assembly 1 includes: two reels 11, and a turbine group 12; wherein two of the reels 11 are engaged; the worm shaft sleeve 21 is meshed with one of the reels 11 through the worm wheel set 12; the worm shaft sleeve 21 drives the turbine in the turbine group 12 to rotate so as to control the two reels 11 to rotate in a meshed manner.
In the present embodiment, both the two reels 11 and the turbine set 12 are disposed in the housing 4, the hole member 24 is fixedly disposed in the housing 4, and the damping fin 22 is fixedly disposed in the hole member 24, wherein the reels 11 are used for winding clotheslines to hang clothes poles, and the turbine set 12 plays a role in transmission; specifically, the worm shaft sleeve 21 is sleeved on the motor rotating shaft 3, the motor rotating shaft 3 drives the worm shaft sleeve 21 to synchronously rotate to drive the reel 11, and after the worm shaft sleeve 21 is assembled with the turbine set 12, the reel 11 is hung with a clothes airing rod and clothes, so that the worm shaft sleeve 21 can receive the reaction force of the turbine set 12, and the reaction force can drive the worm shaft sleeve 21 to axially deform so as to apply larger force on the damping sheet 22, thereby improving self-locking capacity.
In this embodiment, the worm shaft housing 21 and the turbine set 12 may be plastic members, and the plastic members are generally made of polymer materials such as polyimide and polyamide.
In the structure of moving the motor to the side edges of the two reels 11, the self-locking capability of the worm gear and the worm is damaged by deformation caused by the stress of the motor rotating shaft 3, and the worm shaft sleeve 21 is prevented from radial deformation by the limit of the hole piece 24, so that the original radial deformation force is adjusted to be consistent with the axial direction, and the axial deformation of the worm shaft sleeve 21 is caused to generate enough pressure to be propped against the damping piece 22, thereby obtaining enough self-locking force.
As shown in fig. 4, in this embodiment, the locking mechanism 2 further includes: a coupling 23; the worm shaft sleeve 21 is sleeved on the motor rotating shaft 3 through a coupler 23. In this embodiment, the worm shaft sleeve 21 is a metal piece, the turbine set 12 is a plastic piece, the coupling 23 is a plastic piece, and the plastic piece is generally made of polymer materials such as polyimide, polyamide, etc.; the worm shaft sleeve 21 is a metal piece, so that abrasion with the turbine can be reduced, the overall service life is prolonged, but the axial deformation of the metal piece is reduced, the self-locking capacity is reduced, the coupler 23 is a plastic piece, and in order to overcome the defects, certain axial deformation is generated between the worm shaft sleeve 21 and the motor rotating shaft 3 during self-locking, and the abrasion of the turbine is reduced, and the self-locking capacity is maintained.

In this embodiment, at least one limiting boss 232 is disposed on a side wall of the coupling 23; the bottom surface of the worm shaft sleeve 21 is provided with at least one limiting notch 211 which is matched with the limiting boss 232; the worm shaft sleeve 21 is sleeved on the coupler 23, so that the corresponding limiting notch 211 is matched with the corresponding limiting boss 232.
In this embodiment, since the rotating shaft of the motor is cylindrical, in order to prevent the coupling 23 sleeved thereon from rotating, a limiting platform 31 is milled out of the side wall of the rotating shaft 3 of the motor so that the cross section of the rotating shaft 3 of the motor is not circular, thereby preventing the coupling 23 sleeved thereon from rotating.
In the present embodiment, the inside of the worm shaft housing 21 is a circular through hole, and in order to prevent the worm shaft housing 21 and the coupling 23 from rotating, the rotation is prevented by providing the stopper boss 232 and the stopper notch 211.
