[0002] The lifting and lowering of the clothes drying rod of the electric clothes drying machine is achieved through a lifting and lowering driving device; specifically, the lifting and lowering driving device includes a shell, a motor, a left wire drum and a right wire drum.

[0003] During the lifting process of the clothes-drying rod, the lifting drive device is required to control the upper and lower limits of the clothes-drying rod, that is, to use the triggering of the micro switch to control the motor to stop rotating.

[0019] An adjusting portion extending out of the cover plate is provided above the transmission tooth portion, and an adjusting hole is provided on the adjusting portion.

[0020] A further preferred technical solution of the present invention is: the transmission assembly comprises a screw and a composite transmission gear arranged on the output shaft of the motor, and the composite transmission gear comprises an integrated upper gear and a lower gear;

[0021] The first winch drum comprises a first winch drum at a lower portion and a first drum gear at an upper portion, and the second winch drum comprises a second winch drum at a lower portion and a second drum gear at an upper portion;

[0022] The screw rod is meshed with the lower gear, the upper gear is meshed with the first disc gear, and the first disc gear is meshed with the second disc gear.

[0023] A further preferred technical solution of the present invention is: a reference mark is provided on the cover plate, and a scale representing the length of the wire rope is provided on the circumferential inner edge of the second rotating disk; when the tool is inserted into the adjustment hole, the transmission gear is rotated by rotating the adjustment part and then the second rotating disk is rotated; the rotation amplitude of the second rotating disk relative to the reference mark represents the adjustment length of the wire rope.

[0029] Compared with the prior art, the advantages of the present invention are: in this technical solution, the upper and lower limits of the clothes-drying rod are controlled by a single winding drum, which reduces the cumulative error caused by the coordination of multiple components. This technical means can more accurately control the clothes-drying rod to stop at the desired upper and lower limit positions, significantly improving the accuracy of the clothes-drying rod lifting and lowering. Specifically, the transmission path of a single winding drum is more direct, reducing the error accumulation of the intermediate links, thereby ensuring that the clothes-drying rod can accurately reach the preset position during each lifting process.

[0030] In addition, the technical solution adopts a single capstan to control the upper and lower limits, and its transmission path is more concise. By optimizing the design of the transmission component, the intermediate transmission links and possible mechanical interference points are reduced. For example, through the reasonable configuration of the first gear set and the second gear set, efficient power transmission is achieved, while avoiding the unstable factors caused by multi-stage transmission.

[0031] Furthermore, the technical solution controls the upper and lower limits through a single winding drum, and the control of the upper and lower limits can be based on the same set of parameters and operating mechanisms. This unified control standard not only simplifies the complexity of the system, but also improves the control accuracy and reliability. For example, only one winding drum and micro switch need to be calibrated to achieve precise lifting and lowering control of the clothes drying pole. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0043] like Figures 1 to 5As shown, the drying rod lifting drive device 100 is an intelligent device for controlling the lifting of the drying rod, which is widely used in electric clothes drying machines. The device mainly includes a motor 101, a twisting device 102 and a housing 30. The twisting device is composed of a first twisting drum 10 and a second twisting drum 20. The motor 101 drives the two twisting drums to rotate through a transmission assembly 40, thereby realizing the precise rise and fall of the drying rod. The housing 30 serves as a supporting frame of the device, and its structure is compact and sturdy, which can effectively protect the internal components. The transmission assembly 40 uses a screw 41 and a compound transmission gear 42 to efficiently transmit the power of the motor to the twisting drum, ensuring the stability and efficiency of the transmission.

[0044] The present invention aims to achieve precise limit control of the clothes-drying rod through the upper limit micro switch a and the lower limit micro switch b, avoiding the inconvenience of use caused by position deviation. Compared with the traditional clothes-drying rod lifting device, the present invention has significant advantages: the upper and lower limits are controlled by a single capstan, which reduces the cumulative error caused by the coordination of multiple components, and can more accurately control the clothes-drying rod to stop at the required upper and lower limit positions; the transmission path is simpler, reducing the intermediate transmission links and mechanical interference points, and improving the transmission stability; only one capstan and the micro switch need to be calibrated, which simplifies the calibration process and improves the calibration accuracy. The specific technical scheme will be explained below, as follows:

[0045] The shell 30 is an important part of the lifting drive device for the drying rod. Its structural layout is exquisite and highly functional, and it mainly includes a bottom wall, a peripheral wall and a top wall. The bottom wall provides a solid support foundation for the entire device to ensure that the device remains stable during operation; the peripheral wall protects the internal components to prevent external dust, debris and accidental collisions from damaging the internal precision parts; the top wall not only provides an installation platform for the upper structure of the device, but also integrates multiple functional areas, such as the upper limit micro switch, the lower limit micro switch and the installation position of other sensors. These designs make the shell 30 not only have good protection performance, but also effectively support the intelligent operation of the device, providing a reliable hardware foundation for the precise lifting control of the drying rod.

[0046] The top wall 11 corresponding to the first capstan 10 is provided with a lower limit micro switch b and an upper limit micro switch a, respectively. These two micro switches play a vital role in the lifting drive device of the drying rod. When the drying rod descends to the lowest position, the first toggle member 51 on the first capstan 10 will touch the lower limit micro switch b, trigger the switch and stop the motor from rotating, thereby ensuring that the drying rod stops accurately at the lowest position. Similarly, when the drying rod rises to the highest position, the second toggle member 61 on the second rotating disk 60 will touch the upper limit micro switch a, trigger the switch and stop the motor from rotating, thereby ensuring that the drying rod stops accurately at the highest position; avoiding damage or malfunction of the drying rod due to excessive lifting.

[0047] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in the air-drying rod lifting drive device 100, a first rotating disk 50 is installed on the top wall 11 of the first capstan 10, and the rotating disk is one of the key components of the transmission system of the entire device. A first toggle member 51 is provided on the outer periphery of the first rotating disk 50, and its shape and position are carefully designed to accurately trigger the lower limit micro switch b during the descent of the air-drying rod. At the same time, a second rotating disk 60 is also installed on the first rotating disk 50, and a second toggle member 61 is provided on the outer periphery of the second rotating disk 60, which is used to trigger the upper limit micro switch a during the ascent of the air-drying rod; the transmission efficiency and reliability are improved through the layered design.

[0048] The first capstan 10 and the first rotating disk 50 are driven by the first gear set c, which includes a top tooth c1 fixed on the first capstan 10, a compound tooth c2 installed on the top wall 11, and a first inner ring tooth c3 in the first rotating disk 50. The compound tooth c2 is composed of an integrated upper tooth portion c21 and a lower tooth portion c22, wherein the top tooth c1 meshes with the lower tooth portion c22, and the upper tooth portion c21 meshes with the first inner ring tooth c3, thereby efficiently transmitting the rotational motion of the first capstan 10 to the first rotating disk 50.

[0049] Similarly, the second capstan 20 and the second rotating disk 60 are driven by the second gear set d, which includes a drive tooth d1 eccentrically mounted on the first rotating disk 50 and a second inner ring tooth d2 on the second rotating disk 60. The lower part of the drive tooth d1 is a plug-in column d11, which is freely rotatably located in the insertion hole 52 of the first rotating disk 50, and the drive tooth portion d12 on the upper part is meshed with the second inner ring tooth d2 to realize the rotation of the second rotating disk 60. This gear set technical means not only ensures the smoothness of the transmission, but also realizes complex motion conversion through the eccentric drive tooth d1.

[0050] During the lifting process of the clothes-drying rod, the movement direction and position control of the first rotating disk 50 and the second rotating disk 60 are very important. When the first rotating disk 50 rotates in the first direction (usually clockwise), the first toggle member 51 touches the lower limit micro switch b installed on the top wall 11, triggering the switch and sending a signal to stop the motor from rotating, thereby ensuring that the clothes-drying rod stops accurately at the lowest position. This process prevents the clothes-drying rod from being damaged or malfunctioning due to excessive descent through the precise triggering of the micro switch.

[0051] Similarly, when the second rotating disk 60 rotates in the second direction (usually counterclockwise), the second toggle member 61 touches the upper limit micro switch a, triggering the switch and stopping the motor, ensuring that the clothes drying rod stops accurately at the highest position. This two-way limit control technology not only improves the accuracy of the clothes drying rod lifting and lowering, but also enhances the safety of use, providing users with a more reliable and convenient clothes drying experience.

[0052] It is further necessary to clarify that the first gear set c is composed of a top tooth c1 fixed on the first capstan drum 10, a compound tooth c2 mounted on the top wall 11, and a first inner ring tooth c3 in the first rotating disk 50. The top tooth c1 passes through the top wall 11 and meshes with the lower tooth portion c22 of the compound tooth c2, while the upper tooth portion c21 of the compound tooth c2 meshes with the first inner ring tooth c3 in the first rotating disk 50, as shown in FIG. Figure 7 This structure not only ensures that power is efficiently transmitted from the first capstan 10 to the first rotating disk 50, but also realizes the adjustment of the transmission ratio and the conversion of the movement direction through the upper and lower teeth of the composite tooth c2.

[0053] The second gear set d is used to transfer power from the first rotating disk 50 to the second rotating disk 60. Figure 4 and Figure 5 As shown, the gear set includes a transmission tooth d1 eccentrically mounted on the first rotating disk 50 and a second inner ring tooth d2 on the second rotating disk 60. The transmission tooth d1 is composed of a lower plug-in column d11 and an upper transmission tooth portion d12. The plug-in column d11 is located in the plug hole 52 on the first rotating disk 50 and can rotate freely. The transmission tooth portion d12 meshes with the second inner ring tooth d2 on the second rotating disk 60. Through this eccentric mechanism, the second rotating disk 60 can achieve a different rotation direction from the first rotating disk 50.

[0054] In addition, it should be noted that in the drying rod lifting drive device, a central column 13 is provided on the top wall 11 for supporting and positioning the first rotating disk 50 and indirectly supporting the second rotating disk 60. The central hole 53 of the first rotating disk 50 cooperates with the central column 13 to ensure stable rotation of the rotating disk.

[0055] The center of the second rotating disk 60 is provided with a through hole 62, and the lower part of the outer circumference thereof is provided with a second inner ring tooth d2 for meshing with the transmission tooth d1. The upper part of the outer circumference of the through hole 62 is provided with a step 63 for installing a cover plate 70. The cover plate 70 is fixed to the first rotating disk 50 by cooperating with the step 63, and plays a role of protection and sealing.

[0056] An adjusting portion v is provided above the transmission tooth portion d12, and the adjusting portion v extends out of the cover plate 70 and is exposed through the operating hole 71 on the cover plate, so as to facilitate external operation. An adjusting hole d14 is provided on the adjusting portion v, preferably, as Figure 8As shown, the shape of the hole is cross or hexagon socket, which is convenient for adjustment using standard tools.

[0057] In addition, a reference mark (preferably a pointing arrow) is provided on the cover plate 70, and a scale representing the length of the steel wire rope is provided on the inner circumferential edge of the second rotating disk 60. By inserting a tool into the adjustment hole d14 and rotating the adjustment portion v, the transmission tooth portion d12 can be driven to rotate, and then the second rotating disk 60 can be driven to rotate relative to the first rotating disk 50, so as to achieve the purpose of adjusting the relative position of the second rotating disk 60 (that is, to achieve the purpose of adjusting the rotation amplitude of the second toggle member 61 to the upper limit micro switch a). At this time, the rotation amplitude of the second rotating disk 60 relative to the reference mark can directly reflect the adjustment length of the steel wire rope, that is, the position of the highest upper limit of the drying rod can be adjusted.

[0058] In addition, preferably, a center column 13 is provided on the top wall 11, and the center hole 53 of the first rotating disk 50 cooperates with the center column 13 to ensure that the first rotating disk 50 maintains a stable axial position and coaxiality during rotation, thereby achieving a smooth transmission effect. A through hole 62 is provided at the center of the second rotating disk 60, and a second inner ring tooth d2 is provided at the lower part of the outer periphery thereof, which is used to engage with the transmission tooth d1 to achieve power transmission. A step 63 is designed at the upper part of the outer periphery of the through hole 62, and the step 63 is used to install the cover plate 70. The cover plate 70 is tightly fixed on the second rotating disk 60 by cooperating with the step 63, which plays a role in protecting the internal structure and preventing dust and debris from entering, while providing support and guidance for the adjustment portion v of the transmission tooth d1.

[0059] It should be noted that the transmission assembly 40 Figure 6 As shown, in the airing rod lifting drive device, the transmission assembly 40 is the core component for optimizing power transmission and transmission efficiency. Specifically, the transmission assembly 40 includes a screw 41 and a compound transmission gear 42 arranged on the motor output shaft. The compound transmission gear 42 is composed of an upper gear 421 and a lower gear 422 that are integrated. The first winch drum 10 is composed of a first winch drum 14 at the bottom and a first disc gear 12 at the top, while the second winch drum 20 is composed of a second winch drum 21 at the bottom and a second disc gear 22 at the top. The transmission path is as follows: the screw 41 is meshed with the lower gear 422 to transmit the power of the motor to the compound transmission gear 42. The upper gear 421 of the compound transmission gear 42 is meshed with the first disc gear 12 to drive the first winch drum 10 to rotate. The first disc gear 12 is further meshed with the second disc gear 22 to realize the rotation of the second winch drum 20. This multi-stage transmission not only improves the transmission efficiency, but also reduces the vibration and noise during operation by optimizing the meshing angle and clearance of the gears.

[0060] Preferably, the cross-sectional shape of the first toggle member 51 and the second toggle member 61 is elliptical or circular, and the outer end wall surfaces of the first and second toggle members are provided with anti-skid textures to improve the contact reliability with the micro switch. This shape can ensure that the toggle member is subjected to a more uniform force when in contact with the micro switch, and reduce the contact stress concentration caused by irregular shapes. Moreover, providing an anti-skid texture on the outer end wall surface of the toggle member can significantly increase the friction of the contact surface and reduce poor contact caused by sliding.

[0061] Next, the assembly technology of the upper and lower components is described. A concave cavity f is provided at the center of the first rotating disk 50, and the center hole 53 is located in the concave cavity f. A plurality of vertical hooks r1 are arranged at intervals around the outer circumference of the center hole 53, and a buckle hole r2 for the vertical hooks r1 to be inserted is provided on the cover plate 70; the vertical hooks r1 cooperate with the buckle hole r2 to realize the rapid installation and fixation of the first rotating disk 50 and the cover plate 70.

[0062] A vertical threaded hole is provided in the middle of the center column 13 on the top wall 11 for installing a limit adjustment screw 80. A positioning hole 72 is provided in the middle of the cover plate 70, and the positioning hole 72 is aligned with the vertical threaded hole of the center column 13. The limit adjustment screw 80 passes through the positioning hole 72 of the cover plate 70, the through hole 62 of the second rotating disk 60, and the center hole 53 of the first rotating disk 50 in sequence, and finally cooperates with the vertical threaded hole of the center column 13 to achieve the fastening of the entire device.

[0063] During actual assembly, in the drying rod lifting drive device, the main technical purpose of the limit adjustment screw 80 is to ensure the stability of the device components when not in operation, and to prevent loosening or displacement due to external vibration or impact. The core of this technical means is to improve the reliability and durability of the entire device through reasonable mechanical constraints, while avoiding the normal operation of the device being affected by loose components.

[0064] In addition, the limit adjustment screw 80 also takes into account the impact on the normal transmission of the gear set. Avoid excessive squeezing of the rotating disk by the limit adjustment screw 80, and the meshing transmission of the gear set can still work normally. Thus, the needs of fixation and transmission are balanced, ensuring that the device can maintain stability during operation and achieve efficient transmission function.
