Detailed Implementation

[0021] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In related technologies, drying devices typically include drying racks. Some drying racks have movable drying rods, which are connected to the base of the rack body via movable components. Normally, the movable drying rods are folded close to the rack body; in use, they need to be pulled outwards and flipped downwards relative to the rack body. However, existing movable drying rods rely on manual adjustment to pull them outwards and flip them downwards to a position below the rack body. This manual operation is not only relatively cumbersome but also prone to jamming and unevenness during the opening and downward flipping process due to improper pulling position or uneven force, affecting the user experience.

[0025] The inventors considered using a drive component to provide power and enable the movable drying rack to automatically tilt downwards. However, they found that if a drive component was used to drive the movable drying rack to tilt, the instantaneous tilting of the movable component would cause a sudden increase in load on the drive component, affecting its stability and also compromising structural safety.

[0026] To address the aforementioned issues, this application provides a drying rack that uses a drive component to move a movable component, thereby adjusting the movable drying rod between different positions. This eliminates the need for manual operation, improving convenience and ensuring smooth, uninterrupted movement of the drying rod through stable power output. Furthermore, a buffer structure is incorporated between the movable component and the base to provide support when the component flips over. This not only prevents excessive impact from causing structural damage when the component tilts down, but also allows for smoother and more stable opening and closing of the drying rod, and reduces the load on the drive component, thus improving reliability.

[0027] The drying rack described in this application can be used in various drying devices. For example, in an electric clothes dryer, the drying rack is connected to the bottom of the main unit via a connecting rope or scissor bracket; a wall-mounted drying rack is installed on a vertical wall; and a floor-standing drying rack is supported on the ground by a stand. An example of a wall-mounted drying rack is a towel rack installed on a bathroom wall.

[0028] The following reference Figures 1 to 18 This application describes the clothes drying rack and clothes drying machine. To facilitate understanding of the fit between the components, the accompanying drawings illustrate the width direction (x-direction) and length direction (y-direction). Reference Figures 1 to 5 The drying rack includes a main body, which in turn includes a base 13. The drying rack also includes a movable component 22, a movable drying rod 30, and a buffer structure 40. In some embodiments, the drying rack includes a drive component 21 disposed on the base 13. In other embodiments, the base 13 of the drying rack does not have a drive component 21. The following description continues with an example where the base 13 of the drying rack has a drive component 21.

[0029] The clothes drying rack includes a main unit (not shown in the diagram), a drying rack, and connecting components 60. The main body of the drying rack is connected to the main unit via the connecting components 60. Optionally, there are two sets of connecting components 60, spaced apart along the length of the drying rack. The drying rack is connected to the lower side of the main unit via the two sets of connecting components 60. Each set of connecting components 60 includes a connecting rope, which can be made of a high-strength material such as steel wire rope. The main unit has a winding and unwinding assembly inside, with both ends of the connecting rope connected to the winding and unwinding assembly and the main body of the drying rack, respectively. By winding and unwinding the connecting rope through the winding and unwinding assembly, the main body of the drying rack can be raised or lowered, thereby raising or lowering the entire intelligent telescopic drying rack. Optionally, each set of connecting components 60 includes a folding rod assembly, which can be a scissor-type assembly. The folding rod assembly extends when the drying rack rises and retracts when the drying rack lowers. The folding rod assembly is used to improve the stability of the drying rack during lifting and lowering, providing better wind resistance and stability.

[0030] Figure 5 An exploded structural diagram of the base 13 and its internal structure is shown. A driving component 21 is disposed on the base 13, and a movable component 22 is movably disposed on the base 13. One end of the movable component 22 is connected to the driving component 21, and the other end is connected to the movable drying rod 30. The driving component 21 drives the movable component 22 to move relative to the base 13, thereby driving the movable drying rod 30 to move. The movable component 22 can extend out of the base 13 under the action of the driving component 21 (e.g., the movable component 22 extends from...). Figure 14 The state in the middle is switched to Figure 15 (in the state), and the movable component 22, after extending a certain distance from the base 13, can be flipped downward relative to the base 13 to the flipped-down position (e.g. Figures 8 to 11 (Illustration), thereby moving the movable drying rod 30 to the downward position. Figure 1 In the middle position, both the movable component 22 and the movable drying rod 30 are in the folded-down position. When the movable drying rod 30 is in the folded-down position, it is located below the base 13 and maintains a certain distance from the base 13, making it convenient to hang items to be dried on the movable drying rod 30. The movable component 22 can also be flipped upward relative to the base 13 and retracted into the base 13 under the action of the drive component 21, thereby driving the movable drying rod 30 to move to the retracted position. When the movable drying rod 30 is in the retracted position, it is close to the base 13 and can be supported to maintain its current position, for example, supported by the base 13, for example, from... Figure 1 Status switch to Figure 4 During the process, the movable component 22 flips upward and retracts inward to the base 13 until the movable drying rod 30 is supported and will not fall.

[0031] In related technologies, manually opening or retracting the movable drying rod 30 can easily cause jamming due to uneven force at both ends, requiring frequent adjustments to the force application method (such as adjusting the hand's force application position and changing the amount of force applied by both hands) to complete the operation, making it difficult to operate. This application directly drives the movable component 22 to reciprocate through the drive component 21 on the base 13, enabling the movable drying rod 30 to quickly adjust between the retracted and folded states without manual intervention, ensuring smooth movement of the movable drying rod 30 and improving the user experience.

[0032] In this application, the drying rack also includes a buffer structure 40, which is disposed on the base 13 and / or the movable member 22. The buffer structure 40 has a support part 41, which can support the movable member 22 during the flipping process.

[0033] For example, the base 13 extends in the left-right direction and is provided with at least one movable member 22. The movable member 22 can move to the left under the drive of the drive component 21, and after extending out of the base 13, it can flip downward relative to the base 13. The buffer structure 40 can be provided on the left side of the base 13 or the right side of the movable member 22. If the buffer structure 40 is provided on the left side of the base 13, its support part 41 protrudes from the left side surface of the base 13. When the movable member 22 extends from the left side of the base 13, it will flip downward under its own weight and the weight of the movable drying rod 30, and contact the support part 41 through its right side surface, transmitting the flipping force to the support part 41. When the movable member 22 just flips down, the support part 41 provides initial support for a smooth start; when flipping to the middle stage, the support part 41 continuously counteracts the impact of gravity to avoid sudden changes in flipping speed; when approaching the flipping position, the support part 41 buffers inertia to prevent the movable member 22 from colliding with the structure below. That is, the support part 41 can withstand and absorb the impact force of the overturning, and the reaction force allows the movable component 22 to rotate smoothly and evenly. It also avoids problems such as the movable component 22 impacting the base 13, the short-term load increase of the drive component 21, and the shaking of the movable drying rod 30.

[0034] When the movable component 22 flips upward to reset, the support part 41 assists the movable component 22 to overcome gravity and flip upward smoothly, reducing the load requirements on the drive component 21 and preventing jamming or rebound due to insufficient power during the process of the drive component 21 pulling the movable component 22 back to flip upward, ensuring that the movable drying rod 30 can smoothly return to the retracted position and approach the base 13.

[0035] The movable component 22 of this application faces the following two problems during the process of extending outward from the base 13 under the action of the driven component 21 and flipping downward relative to the base 13: First, when the movable component 22 is about to flip downwards, the lever arm of the base 13 on it decreases sharply, which will cause it to flip rapidly and easily impact the base 13, affecting structural safety.

[0036] Second, the movement of the movable component 22 is divided into two stages: In the first stage, the driving component 21 applies a force F1 to drive the movable component 22 to move outward to the extended position. At this time, the extended part of the movable component 22 is not restricted by the rotation of the base 13 and can flip downward under its own weight. In the second stage, the part of the movable component 22 that extends out of the base 13 flips from the horizontal posture to the vertical or near-vertical posture after being detached from the support of the base 13. The driving component 21 needs to apply a reverse force F2 to balance the flipping torque. The flipping torque is the product of gravity G and lever arm L1. The larger the lever arm L1 is, the higher the load requirement of the driving component 21. If the driving component 21 is a motor, the motor needs to have higher power, which increases the cost.

[0037] In this application, by adding a buffer structure 40 between the base 13 and the movable member 22, the following advantages are available: First, the support part 41 of the buffer structure 40 can form contact support with the movable component 22 in advance, or through magnetic support, at the critical stage when the movable component 22 is about to flip downwards and the lever arm begins to decrease sharply. As the movable component 22 continues to flip downwards, the support part 41 always maintains dynamic support for the movable component 22, preventing it from continuously accelerating due to gravity, thereby preventing the movable component 22 from impacting the base 13 with excessive kinetic energy, reducing impact damage to the connection parts (such as hinge points) between the movable component 22 and the base 13, and ensuring the safety and service life of the overall structure.

[0038] Secondly, by using the buffer structure 40 as a variable arm structure, during the second stage of the movement of the movable component 22, the support part 41 supports the movable component 22, such as... Figure 6 As illustrated, by supporting point B of the movable member 22 through the support part 41 of the buffer structure 40, the starting point of the lever arm can be adjusted from point A to point B, reducing the lever arm L1 to L2. This reduces the flipping torque to the product of gravity G and lever arm L2. At this time, the load force F2 borne by the driving component 21 is reduced from the product of G and L1 to the product of G and L2, thereby reducing the load requirement of the driving component 21. When the driving component 21 is a motor, this improves the motor's operational stability and reduces the power requirements, which is beneficial for controlling motor costs. It should be noted that during the downward flipping of the movable member 22 relative to the base 13, L2 can be either fixed or continuously decreasing.

[0039] The drive component 21 can actively transmit power or drive the power in a linkage manner to transmit power to the movable component 22, so that the movable component 22 can reciprocate, thereby driving the rod to reciprocate at least between the retracted position and the lower position. (Refer to...) Figure 12In this embodiment, the driving component 21 is a power source, such as a motor, and the motor shaft is connected to the movable component 22 via a transmission connection. In another embodiment, the driving component 21 is a linkage structure (not shown in the figure), and the drying rack body is suspended from the ceiling in a height-adjustable manner. The driving component 21 can be linked with the lifting and lowering movement of the drying rack body to slide or rotate back and forth on the base 13 during the rising and falling of the drying rack body. In another embodiment, the driving component 21 is a linkage structure (not shown in the figure), and the drying rod of the drying rack body is a telescopic component. The driving component 21, which is disposed on the base 13, is linked with the telescopic movement of the drying rod to slide or rotate back and forth on the base 13 during the extension and retraction of the drying rod.

[0040] In other embodiments, when the base 13 of the drying rack is not equipped with a drive component 21, the user can manually operate the rack by holding the movable drying rod 30, or holding the movable component 22, or holding a handle that is fixedly connected to the movable component 22 and exposed outside the base 13, to pull out the movable component 22 and the movable drying rod 30 and flip it downwards, or flip the movable component 22 and the movable drying rod upwards and retract them. This allows the movable component 22 to extend or retract into the base 13, and allows the movable component 22 to flip downwards or upwards relative to the base 13, thereby adjusting the position of the movable drying rod 30.

[0041] In one embodiment, the movable member 22 has a retracted position, an extended position, and a folded-down position.

[0042] like Figure 3 , Figure 4 As shown, when the movable component 22 is in the retracted position, it is supported by the base 13 and its rotation is restricted. At this time, the movable drying rod 30 is in a retracted state close to the base 13 and folded up on the base 13. The overall structure of the drying rack is compact, does not occupy extra space, and saves space.

[0043] like Figure 9 Indicating that when the movable member 22 is in the extended position, the movable member 22 extends out of the base 13, and the movable member 22 is freed from the rotation constraint of the base 13, and can rotate downward relative to the base 13 to the downward position. At this time, there is no obstruction of the base 13 on the rotation path of the part of the movable member 22 that can rotate relative to the base 13, and the movable member 22 has the conditions to be rotated downward, but has not yet started to rotate. The movable drying rod 30 is located on the horizontal outside of the base 13 and has not yet moved downward with the movable member 22 towards the base 13. In this critical state, the part of the movable member 22 that extends outside the base 13 and is not restricted from rotating downward is about to rotate downward under the action of gravity.

[0044] like Figure 11As shown, the movable component 22 is in the flipped-down position. At this time, the part of the movable component 22 extending outside the base 13 is in a vertical or roughly vertical posture. The movable drying rod 30 is suspended in the space below the base 13 and maintains a certain height difference with the base 13. The movable drying rod 30 is in the flipped-down state and can be used for drying.

[0045] The support portion 41 of the buffer structure 40 can support the movable member 22 when it flips between the extended position and the downward position. That is, the support portion 41 supports the movable member 22 when the part of the movable member 22 extending out of the base 13 flips downward relative to the base 13 or flips upward relative to the base 13.

[0046] Optionally, the driving component 21 can drive the movable component 22 to reciprocate along the base 13. The driving component 21 can apply a force F1 to the movable component 22 (F1 as shown in the image). Figure 6 (Illustrative diagram) This allows the movable component 22 to move from the retracted position to the extended position, and the transmission of power to the movable component 22 stops when it reaches the extended position. Upon reaching the extended position, the movable component 22 can flip downwards under gravity to a tilted position, thereby moving the movable drying rod 30 to a position below the base 13 and maintaining a height difference with the base 13, facilitating user access to the movable drying rod 30. The driving component 21 can apply a force F2 to the movable component 22, causing it to flip upwards relative to the base 13, from a vertical or near-vertical posture to a horizontal or near-horizontal posture. Then, the movable component 22 moves laterally back to the base 13, returning it to the retracted position.

[0047] During the process of the movable component 22 flipping downwards from the extended position to the flipped-down position, the support part 41 mainly serves to buffer the impact force, protect the base 13, protect the movable component 22, protect the drive component 21, and stabilize the flipping trajectory of the movable component 22. Since the movable component 22 relies on gravity to flip downwards during this stage, when the drive component 21 pushes the movable component 22 outwards to the extended position where it is about to flip downwards, the movable component 22 is prone to rapid falling and flipping due to the sudden reduction of the support lever arm. The support part 41 can absorb part or all of the impact force generated by the flipping by supporting the movable component 22 (such as through mechanical contact or elastic deformation), avoiding wear or shaking caused by hard collision between the movable component 22 and the base 13. At the same time, it shortens the effective lever arm of gravity, reduces the torque transmitted to the drive component 21 in the opposite direction, prevents the drive component 21 from being passively overloaded and damaged, and ensures that the movable drying rod 30 smoothly reaches the drying position below the base 13.

[0048] Under the action of the drive component 21, during the process of the movable component 22 flipping from the lower position to the extended position, the drive component 21 needs to overcome gravity and inertia. The support part 41 can provide auxiliary support force in the same direction as the flipping, share part of the load, reduce the power requirement of the drive component 21 and avoid jamming, and ensure that the movable component 22 reaches the extended position in a horizontal state, laying a smooth foundation for the subsequent retraction of the base 13 and reset to the storage position.

[0049] The active component 22 of this application can be configured in at least the following two ways.

[0050] One of the configuration methods for active component 22: like Figure 6 The movable component 22 includes a slider 221 and a movable rod 222. The slider 221 is reciprocally mounted on the base 13 and is connected to the drive component 21. The first end of the movable rod 222 is rotatably connected to the slider 221 via a pivot shaft; for example, the slider 221 is rotatably connected to the movable rod 222 via a pivot shaft 223. The second end of the movable rod 222 is connected to the movable drying rod 30.

[0051] In this embodiment, the sliding member 221 is connected to the driving component 21 via a transmission mechanism. For example, the driving component 21 is a rotary actuator, and it is connected to the sliding member 221 via a lead screw pair. The driving component 21 drives the lead screw in the lead screw pair to rotate, thereby causing the sliding member 221, which is threadedly connected to and sleeved on the lead screw, to reciprocate along the lead screw. In other embodiments, the driving component 21 can also be connected to the sliding member 221 via a transmission structure such as a gear, rack, or synchronous belt.

[0052] When the driving component 21 drives the sliding member 221 to move outward, it pushes the movable rod 222 out of the base 13. After the rotating connection between the movable rod 222 and the sliding member 221 disengages from the support of the base 13, the movable rod 222, under its own weight and the weight of the movable drying rod 30, flips downward around the pivot point, cooperating with the support part 41 of the buffer structure 40 to achieve a smooth downward swing, ultimately positioning the movable drying rod 30 below the base 13 for convenient drying. When the driving component 21 drives the sliding member 221 to move inward, the movable rod 222 flips upward around the pivot point to a horizontal or near-horizontal position, and then the sliding member 221 retracts back into the base 13.

[0053] In this configuration of the movable component 22, the driving component 21 controls the lateral movement of the sliding member 221, thereby enabling the movable rod 222 to move outward, flip downward, flip upward, and move inward. The control logic is simple. The driving component 21 can directly drive the sliding member 221 to extend or retract stably along a straight line. The extension length of the movable rod 222 has high precision and stability, and is not prone to jamming or unevenness. The fixed position of the flipping fulcrum of the movable rod 222, combined with the stable support of the sliding member 221, can prevent the movable drying rod 30 from wobbling.

[0054] Configuration method 2 for active component 22: like Figure 16 The movable component 22 is illustrated as a series of hinged blocks 224, which are connected sequentially. For example, adjacent hinged blocks 224 are hinged together by pins. In the movable component 22, the first hinged block 224 is driven by the drive component 21, and the last hinged block 224 is connected to the movable drying rod 30. When the drive component 21 drives the first hinged block 224 to move outward, the subsequent hinged blocks 224 unfold and extend outward from the base 13 section by section. After each hinged block 224 extends out of the base 13, it will flip downward under the action of gravity with the adjacent hinge point as the fulcrum. The support part 41 of the buffer structure 40 simultaneously provides support for each hinged block 224 to offset the impact.

[0055] In one embodiment, reference is made to Figure 5 The drying rack has two bases 13, which are spaced apart along the length of the movable drying rod 30. Each base 13 is equipped with a drive component 21. Both ends of the movable drying rod 30 are connected to movable components 22, which are movably mounted on the two bases 13 and are respectively connected to the drive components 21 of the two bases 13.

[0056] During operation, when the movable drying rod 30 needs to be adjusted to hang below the base 13, the two drive components 21 output power through synchronous control (such as the coordination command of a clothes drying machine control system), driving the corresponding movable components 22 to move outward along the base 13. The two drive components 21 synchronously drive the two movable components 22 to extend out of the base 13, so that the two movable components 22 synchronously flip downward, causing both ends of the movable drying rod 30 to synchronously flip downward to a position below the base 13, making it convenient to use the movable drying rod 30 for drying. When it is necessary to retract the movable drying rod 30, the two drive components 21 synchronously drive the two movable components 22 to flip upward and reset, and synchronously drive the movable components 22 to retract back into the base 13, finally causing both ends of the movable drying rod 30 to fit against the base 13 for storage.

[0057] This symmetrical configuration, with drive components 21 at both ends capable of outputting power, ensures synchronous movement of the two movable components 22, resulting in balanced force on both ends of the movable clothes drying rod 30. This prevents the rod from tilting, bending, or flipping and jamming due to unilateral drive. Simultaneously, the synchronous transmission of the dual drives makes the movement trajectory of the movable clothes drying rod 30 more stable, meeting the automation and reliability requirements of electric clothes drying racks. If a user holds the movable clothes drying rod 30 with one hand and pulls it outward, uneven force may cause jamming during opening. However, in this embodiment, the cooperation of the two movable components 22, two bases 13, and two drive components 21 ensures smoother opening and closing of the movable clothes drying rod 30. In one embodiment, the drying rack is suitable for use when suspended below the ceiling, and the drying rack can meet a larger amount of drying and more diverse drying needs.

[0058] The drying rack includes two brackets 12 and two clotheslines 111 positioned between the brackets 12, with each end of the clothesline 111 connected to one of the brackets 12. Each clothesline 111 has two slidably mounted telescopic rods 112, which extend from both ends of the clothesline 111. The two brackets 12 are located between two bases 13, with each base 13 connected to both ends of the telescopic rods 112. There are two movable drying rods 30. Each base 13 has two movable components 22, which extend from both ends of the base 13.

[0059] In other words, the drying rack includes a main frame 101 and two side frames 102. The main frame 101 includes two brackets 12 spaced apart in the front-to-back direction and two clotheslines 111 spaced apart in the left-to-right direction. The side frames 102 include two clothesline telescopic rods 112 spaced apart in the left-to-right direction and a base 13 connecting the two clothesline telescopic rods 112. By sliding the clothesline telescopic rods 112 onto the clotheslines 111, the two side frames 102 can be telescopically positioned on the front and back sides of the main frame 101, respectively. Each side frame 102 can be opened by simultaneously extending two clotheslines 111 from the two clothesline telescopic rods 112, thereby expanding the drying area on the front or back side of the main frame 101. Each movable drying rod 30 is a telescopic rod 2221 that can extend and shorten in the front-back direction. For example, the movable drying rod 30 is a quilt rod, which includes a quilt rod body 31 and two quilt drying telescopic rods 32 that are slidably disposed on the quilt rod body 31. The two quilt drying telescopic rods 32 are respectively connected to the movable components 22 at both ends.

[0060] In practical applications, the drying rack can achieve the following drying modes, and the types and quantities of items to be dried can be flexibly adjusted, taking into account both practicality and space utilization, to meet the diverse drying needs of different families. Drying Mode 1: All clothesline telescopic rods 112 retract to clothesline rods 111, and all quilt telescopic rods 32 retract to the quilt rod body 31. The base 13 is close to the bracket 12, and the two quilt rods are folded together. Users only need to use the two clothesline rods 111 on the main frame 101 to dry everyday clothes. The structure is compact and suitable for scenarios with small balcony space or a small amount of clothing. Drying Mode 2: Both clothesline telescopic rods 112 and quilt telescopic rods 32 retract, with only one or both quilt rods flipped downwards to below the main frame 101. Users can hang quilts, sheets, and other large fabrics on the quilt rods without occupying clothing drying space, suitable for those who only need to dry large home textiles. Drying Mode 3: One or both sides of the side frame 102 extend (clothes drying telescopic rod 112 extends from the clothes drying rod 111), while the two quilt drying rods remain folded. Users can simultaneously dry more clothes using the clothes drying rod 111 on the main frame 101 and the clothes drying telescopic rod 112 on the side frame 102, expanding the drying capacity. This is suitable for scenarios with a large volume of laundry. Drying Mode 4: One or both sides of the side frame 102 extend, and the clothes drying rods on one or both sides are flipped downwards to below the main frame 101. Users can simultaneously dry clothes using the clothes drying rod 111 and the clothes drying telescopic rod 112, and dry large fabrics using the quilt drying rods. This allows for the separate and concentrated drying of clothes and large home textiles, meeting the needs of large-scale drying during seasonal changes.

[0061] The buffer structure 40 of this application can be configured in at least the following two ways.

[0062] One of the configuration methods for buffer structure 40: Reference Figures 6 to 15 The support part 41 is a rotating support arm. During the flipping process of the movable component 22, the rotating support arm rotates relative to the base 13 or the movable component 22 to offset all or part of the flipping impact force. Specifically, when the movable component 22 flips downward from the extended position or flips upward from the flipped position, the rotating support arm rotates synchronously with the movement of the movable component 22.

[0063] For example, the rotating support arm is rotatably mounted on the base 13, and its free end can contact the surface of the movable component 22. When the movable component 22 flips downward, it first contacts the top of the rotating support arm and pushes it to rotate, converting the impact kinetic energy caused by gravity into the rotational kinetic energy of the rotating support arm, gradually offsetting the downward impact, so that the movable component 22 can flip smoothly and uniformly into place; at the same time, as the movable component 22 gradually flips downward, it pushes the rotating support arm to rotate from a roughly vertical state to an inward tilting state, and the lowest point of the contact part between the two gradually moves downward, reducing the load on the driving component 21 through dynamic adjustment of the lever arm.

[0064] When the movable component 22 flips upward, the rotating support arm rises and rotates back to its initial state. The rotation and reset of the rotating support arm provides some support for the movable component 22, and helps the drive component 21 to smoothly pull the movable component 22 up to a horizontal position and retract into the base 13, thus avoiding frequent jumping due to the movable component 22 not being stored smoothly during the storage process.

[0065] The rotating support arm serves as the support part 41 of the buffer structure 40. Firstly, the rotating support arm rotates synchronously with the movable component 22 during the flipping process. It can dynamically adjust its contact position and lever arm length with the movable component 22, always conforming to the entire flipping trajectory of the movable component 22. This ensures continuous and effective buffering of the flipping impact force throughout the entire flipping process of the movable component 22, preventing buffering interruptions and improving the stability of the flipping motion of the movable component 22. Secondly, the rotating support arm does not rely on the elastic deformation of the material to absorb the flipping impact force, making it less prone to fatigue deformation and damage. Thirdly, through dynamic adjustment of the lever arm, the rotating support arm can directly reduce the reverse load transmitted to the drive component 21 during the flipping of the movable component 22, resulting in more precise load reduction on the drive component 21 and better assisting the drive component 21 in achieving smooth transmission.

[0066] Buffer structure 40 configuration method two: Reference Figure 17 , Figure 18 The support part 41 is an elastic support (such as a spring, elastic rubber block, etc.). During the flipping process of the movable component 22, the elastic support undergoes elastic deformation under the compression of the movable component 22 and the base 13, thereby offsetting all or part of the flipping impact force.

[0067] When the movable component 22 flips, the elastic support is in contact with both the movable component 22 and the base 13. For example, the elastic support is connected to the base 13 by means of adhesive, hot melt glue, or screws. When the movable component 22 flips downwards, its flipped side gradually squeezes the elastic support, causing the elastic support to contract and deform towards the base 13, absorbing the instantaneous impact caused by gravity through the accumulation of elastic potential energy. When the movable component 22 flips upwards, the elastic support gradually releases its deformation potential energy as the movable component 22 rises, converting it into auxiliary thrust to buffer the inertial impact of the drive component 21 during the flipping process, while also preventing rigid contact between the movable component 22 and the base 13 when it returns to its original position.

[0068] In one embodiment, reference is made to Figures 6 to 15The buffer structure 40 is configured in one of the above-mentioned configuration methods. To facilitate the installation of the rotatable rotating support arm, the buffer structure 40 also includes a mounting shaft 42 and a mounting base 43. The rotating support arm is rotatably connected to the mounting base 43 via the mounting shaft 42. The mounting base 43 is connected to the base 13 or to the movable component 22 by means of screw fastening, snap-fit ​​connection, etc., thereby stably assembling the rotating support arm in the preset working position of the buffer structure 40.

[0069] For example, the mounting base 43 is installed on the outer end of the base 13 by fastening screws, and the rotating support arm is rotatably connected to the mounting base 43 via the mounting shaft 42. In this way, the rotating support arm, the mounting shaft 42, and the mounting base 43 can be assembled into a module in advance. In the subsequent assembly line of the drying rack, it is only necessary to fix the mounting base 43 in the preset position of the base 13, without the need for shaft through-hole or other docking steps, thus improving assembly efficiency.

[0070] In one embodiment, reference is made to Figures 7 to 10 , Figure 13 The buffer structure 40 is configured in one of the above-mentioned configuration methods. The support part 41 is a rotating support arm, which is rotatably mounted on the base 13 via a mounting shaft 42. The mounting shaft 42 can be directly mounted on the base 13 or mounted on a mounting seat 43 fixed to the base 13. The rotating support arm can be pushed to rotate inward when the movable member 22 flips downward, and the rotating support arm can rotate outward under its own gravity to return to the initial state when the movable member 22 flips upward.

[0071] For example, such as Figure 8 , Figure 11 The rotating support arm's center of gravity is positioned outside its mounting shaft 42. This allows the rotating support arm to remain vertical or approximately vertical under the influence of its outer center of gravity when the movable component 22 does not exert an inward rotational force on it. When the movable component 22 flips downward, it presses against the rotating support arm, causing it to rotate inward. When the movable component 22 flips upward, the rotating support arm loses its pressure and automatically returns to a approximately vertical position with the help of its outer center of gravity. In this embodiment, the rotating support arm achieves automatic reset by its own weight, eliminating the need for reset components such as springs and avoiding the problem of elastic components aging and failing over long-term use. Simultaneously, during the upward flipping of the movable component 22, the rotating support arm maintains contact with the movable component 22 during reset, providing support and ensuring a smooth upward flipping motion.

[0072] Optionally, the rotating support arm is connected to the mounting shaft 42 at the lower end of the rotating support arm. On the one hand, when the movable component 22 (such as the movable rod 222 connecting the movable drying rod 30) flips downward, the part of the rotating support arm that first contacts the movable component 22 is its upper end; as the movable component 22 continues to flip, it will push the rotating support arm to rotate around the mounting shaft 42, and the lowest point of the contact part between the two will gradually move closer to the lower mounting shaft 42 with the rotation; in this process, the rotating support arm continuously buffers the flipping impact force of the movable component 22 through the dynamic downward movement of the contact position, so that the movable component 22 can obtain a balanced buffering force in both the initial stage and the subsequent stage of flipping, thereby achieving a smoother downward flipping and ensuring that the movable drying rod 30 operates smoothly when opened. Secondly, by placing the mounting shaft 42 at the lower end of the rotating support arm, a more reasonable lever arm relationship can be formed between the center of gravity of the rotating support arm and the mounting shaft 42. When the movable component 22 flips upward, the rotating support arm loses the pressure constraint of the movable component 22 and is more likely to rotate outward under its own gravity, returning to the approximately vertical initial state, which facilitates the buffering of the next flipping action of the movable component 22.

[0073] In one embodiment, reference is made to Figure 7 , Figure 9 The support part 41 is a rotating support arm; the rotating support arm has a guide surface 411 and a support surface 412. The guide surface 411 extends from top to bottom outward of the base 13, and the support surface 412 is connected to the lower side of the guide surface 411. During the downward flipping of the movable member 22 relative to the base 13, the guide surface 411 guides the movable member 22 to fit against the support surface 412, so that the rotating support arm rotates with the movable member 22.

[0074] Taking the movable component 22, which includes the sliding member 221 and the movable rod 222, as an example, when the left movable drying rod 30 needs to be used, the driving component 21 pushes the sliding member 221 and the movable rod 222 to move to the left. After the movable rod 222 extends from the left end of the base 13 and the rotation restriction is released, it flips downward under the action of gravity. In the initial stage, the right side of the movable rod 222 first contacts the upper guide surface 411 on the left side of the rotating support arm. Since the guide surface 411 is inclined from top to bottom towards the outside (left side) of the base 13, the lateral component force can guide the rotation trajectory of the movable rod 222 to transition to the support surface 412, avoiding jamming or displacement caused by rigid collision. At the same time, the tilt angle is used to buffer the initial impact and reduce contact noise and wear. As the movable rod 222 continues to flip downward, its right side gradually fits the lower, gentle support surface 412 on the left side of the rotating support arm. The rightward thrust applied by the movable rod 222 drives the entire support arm to flip synchronously to the right. The flat design of the support surface 412 increases the contact area, allowing the impact force to be transmitted evenly and avoiding local stress concentration. At the same time, the stable fit between the two can be achieved by rotating the support arm, which continuously converts the gravitational potential energy of the movable rod 222 into the rotational kinetic energy of the support arm, realizing the downward flipping process of the movable rod 222. The rotating support arm continuously buffers the impact force of the downward flipping of the movable rod 222.

[0075] The inventors discovered that by equipping the base 13 with a retractable movable component 22 that can flip downwards relative to the base 13 after extension, the movable drying rod 30 can be flipped downwards to a space below the main body of the drying rack, maintaining a certain distance between the top of the movable drying rod 30 and the main body of the drying rack, thus facilitating the drying of fabrics. However, the inventors found that in some situations, such as when the weight of the movable component 22 and the movable drying rod 30 exceeds a certain value, the movable component 22 may cause the movable drying rod 30 to fall rapidly relative to the base 13 when it flips downwards. This could potentially startle the user, cause collisions, or damage to the drying rack components. To avoid rapid falls, lightweight movable components 22 and the movable drying rod 30 can be used to reduce their weight and thus slow down the flipping speed. However, this solution has limitations; a lightweight movable drying rod 30 may not meet the requirements for some high-load drying scenarios. In one embodiment, the buffer structure 40 provides cushioning for the movable member 22 during its downward flip relative to the base 13, ensuring that the downward flipping process of the movable member 22 is not a free fall. That is, when the movable member 22 flips downward, it is not only subjected to gravity but also to the force provided by the buffer structure 40, allowing it to flip smoothly and preventing a rapid descent. The buffer structure 40 can be disposed inside the base 13, or it can be disposed outside the base 13.

[0076] Optionally, the process of the movable component 22 extending out of the base 13 and flipping downward relative to the base 13 is a gradual downward flipping process, thereby overcoming the problem of rapid descent. This allows the movable component 22 to drive the rod 30 to flip downward relative to the base 13 in a slow and controllable manner, preventing the rod 30 from falling completely in free fall. Optionally, the process of the movable component 22 driving the rod 30 downward is a uniform or decelerated motion, but the movable component 22 can still drive the rod 30 downward to a preset position, such as the movable component 22 flipping downward to be vertical or substantially perpendicular to the base 13, so that the rod 30 is suspended below the main body of the drying rack.
