Description

Technical Field

[0001] This invention relates to the technical field of clothes drying equipment, and more particularly to a clothes drying rod extension bracket and a clothes drying machine. Background Technology

[0002] Clothes drying racks are a convenient device in modern home life. They can raise and lower the clothes drying rod through a specific mechanical device, so that users can dry clothes at different heights.

[0003] Currently, with technological advancements and diversified consumer demands, clothes drying racks are gradually trending towards smaller designs. The aim is to minimize visual obtrusiveness and enhance aesthetics when not in use. However, while this design optimizes the overall visual appeal, it inevitably reduces the drying area. Therefore, clothes drying racks have been redesigned with telescopic extension capabilities. This allows for expansion of the drying area when clothes need to be hung, without compromising the aesthetics when folded up, providing users with a more flexible and efficient drying experience.

[0004] However, clothes drying racks with extended functions require manual or electronic control to switch the state of the drying rod. Manual control increases the user's workload and affects the user experience, while electronic control makes the overall structure of the clothes drying rack more complex, increasing the overall size of the product and the burden on the traction and lifting components, affecting product stability and increasing the risk of product damage. Summary of the Invention

[0005] The purpose of this invention is to provide a clothes drying rack extension bracket and a clothes drying machine that can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, a clothesline extension bracket is provided, comprising:

[0008] bracket housing;

[0009] A drive component is movably disposed on the bracket housing. The drive component is used to connect with the lifting assembly of the clothes drying equipment. During the process of the bracket housing rising and falling with the lifting assembly of the clothes drying machine, the drive component reciprocates relative to the bracket housing in a preset direction.

[0010] A telescopic component is telescopically disposed on the bracket housing, the telescopic component having a drying position relatively far away from the bracket housing and a storage position relatively close to the bracket housing in its direction of movement;

[0011] A locking mechanism is also provided between the bracket housing and the telescopic component. The locking mechanism is used to lock the telescopic component in the drying position, and the driving component is used to trigger the locking mechanism to unlock when it moves relative to the bracket housing to a preset position.

[0012] As an optional implementation, the locking mechanism includes a first limiting structure and a second limiting structure. The first limiting structure is disposed on the bracket housing, and the second limiting structure is disposed on the telescopic component. One of the first limiting structure and the second limiting structure has a locking position that can lock into the other, and an unlocking position that can disengage from the other.

[0013] The first reset component acts on the first limiting structure or the second limiting structure to make the first limiting structure or the second limiting structure tend to move toward the locked position.

[0014] As an optional implementation, the bracket housing has a hollow first movable part inside, and at least one end of the bracket housing has a telescopic opening that communicates with the first movable part. The telescopic component is movably disposed in the first movable part, and the telescopic component can extend out of the bracket housing through the telescopic opening.

[0015] The bracket housing also has a second movable part formed on one side of the first movable part, a partition is provided between the first movable part and the second movable part, and the driving component is movably disposed in the second movable part;

[0016] The first limiting structure is disposed on the partition.

[0017] As an optional implementation, the first limiting structure is configured as a locking hole penetrating both sides of the partition, with the opposite ends of the locking hole respectively connecting the first movable part and the second movable part;

[0018] The second limiting structure is configured as a locking pin, which is retractably disposed on the telescopic assembly. The first reset component is an elastic element disposed on the telescopic assembly, which acts on the locking pin to make the locking pin tend to extend out of the telescopic assembly.

[0019] As an optional implementation, when the telescopic component is in the drying position and the locking pin is in the locked position, the locking pin passes through the locking hole from the first movable part to the second movable part;

[0020] The locking pin has a guide slope at one end for passing through the locking hole, and the driving component has a top for moving towards the unlocked position by abutting the locking pin through the guide slope on the side near the partition.

[0021] When the locking pin is in the unlocked position, the lower end of the guide bevel is outside the edge of the locking hole.

[0022] As an optional implementation, the telescopic assembly includes a first telescopic frame and a second telescopic frame, both of which can reciprocate synchronously between the drying position and the storage position;

[0023] The driving components are two, and the first telescopic frame and the second telescopic frame are respectively connected to the driving components via a first transmission assembly; or

[0024] The first telescopic frame is connected to the driving component via a first transmission assembly, and the first telescopic frame and the second telescopic frame are connected via a second transmission assembly.

[0025] As an optional implementation, the direction of movement of the driving component is opposite to the direction of movement of the first telescopic frame or the second telescopic frame;

[0026] The first transmission assembly includes:

[0027] The first rack is connected to the driving component for transmission.

[0028] The first transmission gear is rotatably disposed on the bracket housing and meshes with the first rack;

[0029] The second rack is fixedly mounted on the first telescopic frame or the second telescopic frame and meshes with the first transmission gear.

[0030] As an optional implementation, the second transmission assembly includes:

[0031] The third rack is fixedly mounted on the first telescopic frame;

[0032] The second transmission gear is rotatably mounted on the bracket housing and meshes with the third rack;

[0033] The fourth rack is fixedly mounted on the second telescopic frame and meshes with the second transmission gear.

[0034] As an optional implementation, a second reset component is further provided between the bracket housing and the telescopic assembly. The second reset component is used to continuously apply a force to the telescopic assembly to move it toward the storage position.

[0035] The driving component abuts against the first transmission assembly along the first direction. During the movement of the driving component along the first direction, the driving component drives the telescopic assembly to move towards the drying position through the first transmission assembly.

[0036] Secondly, a clothes drying rack is provided, characterized in that it includes:

[0037] The main unit is equipped with a power unit;

[0038] A lifting assembly, the first end of which is mounted on the main unit;

[0039] As described in the first aspect, the second end of the lifting assembly is movably mounted on the bracket housing via the driving component, and the bracket housing is also connected to the power unit via a traction member, and the telescopic assembly is provided with a clothes drying rod.

[0040] The beneficial effects of this invention are as follows: During the process of the bracket housing rising and falling with the lifting component of the clothes drying rack, the driving component can reciprocate relative to the bracket housing in a preset direction. When the bracket housing rises and falls to a preset position, the driving component also moves to a preset position on the bracket housing accordingly, thereby triggering the locking mechanism between the telescopic component and the bracket housing to unlock, so that the telescopic component can be removed from the drying position, so that the clothes drying rod can be reset to the storage state. The user only needs to control the movement of the bracket housing, thereby reducing the operation steps of the clothes drying rod, making the clothes drying rack easier to use, and suitable for more different usage scenarios and user groups.

[0041] The unlocking process of the telescopic component is achieved solely through mechanical transmission, making the overall structure of the clothes drying rack simpler and more reliable. This effectively reduces the overall size and weight of the clothes drying rack, improves its overall visual appeal, reduces the probability of equipment damage, enhances the stability of the clothes drying rack, and facilitates equipment maintenance.

Detailed Implementation

[0063] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," 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 invention based on the specific circumstances.

[0065] 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.

[0066] A clothes drying rack is a common drying tool in modern homes. It allows users to raise and lower the clothesline manually or electrically, making it convenient to hang clothes at different heights. Generally, clothes drying racks come in two types: manual and electric. Manual clothes drying racks use a hand crank or similar control mechanism to raise and lower the clothesline by winding and unwinding the rope; their structure is relatively simple. Electric clothes drying racks, on the other hand, typically use an electric motor to drive the rope and often come with a remote control function, allowing users to easily control the raising and lowering of the clothesline from a distance.

[0067] As the background technology shows, with the advancement of technology and the diversification of consumer demands, clothes drying racks have gradually become smaller in design. The aim is to minimize visual obtrusion when not in use, enhancing aesthetics and making them a part of home décor rather than simply a practical tool. Especially with recessed clothes drying racks, which are typically designed to be embedded in the ceiling or wall, the width and number of drying rods are more restrained, allowing them to be stored within the recessed main unit when not in use, achieving space saving and maintaining a neat and aesthetically pleasing home environment. However, while pursuing aesthetics and space saving, the drying area and expandable accessories offered by the clothes drying rack are also correspondingly limited. It's difficult to achieve a balance between the product's shape and its functionality. This design, while optimizing the overall visual appeal, undoubtedly reduces the drying area provided by the clothes drying rack.

[0068] Therefore, clothes drying racks were later designed with telescopic extension functions. When clothes need to be hung to dry, the clothes rack can be lowered and then extended outward to expand the drying area. When the clothes rack needs to be raised and put away again, it can be retracted and folded without affecting the aesthetics of the stored state, bringing users a more flexible and efficient drying experience.

[0069] However, clothes drying racks with extended functions require manual or electronic control during the switching of the clothesline's state. Manual control necessitates user intervention during both the expansion and contraction of the drying area. After lowering the clothesline, the user must manually pull it out and push it back in after use. This undoubtedly increases the user's workload. Furthermore, if the user forgets to retract the clothesline to ensure the drying area is fully retracted, there is a risk of interference with the main unit when the clothesline rises to its retracted position, potentially damaging the product and affecting the user experience. Electronic control of the clothesline's extension and retraction requires the inclusion of motors and other drive mechanisms within the clothesline. This inevitably leads to a more complex overall structure, increasing the product's size and the burden on the traction and lifting components, affecting product stability and increasing the risk of damage.

[0070] In view of this, this embodiment provides a clothes drying rack extension bracket, which utilizes the reciprocating motion of the lifting component of the clothes drying machine during the lifting and lowering process of the clothes drying rack to achieve linkage with the clothes drying rack, thereby allowing the clothes drying rack to adjust the expansion and contraction of the drying area according to different lifting and lowering states of the clothes drying machine, thus solving the related technical problems mentioned in the background art.

[0071] Please refer to the instruction manual attached. Figures 5-19 The clothesline extension bracket includes a bracket housing 10, a drive component 20, and a telescopic assembly 30. The bracket housing 10 serves as the supporting foundation for the clothesline 100 bracket. In practical applications of the clothesline, it connects to the traction component 82 of the clothesline and, through the drive component 20, to the lifting assembly 90. It also provides the corresponding installation space and position for the telescopic assembly 30, allowing the bracket housing 10 to move synchronously with the lifting assembly 90 under the traction of the traction component 82, ultimately driving the telescopic assembly 30 to rise and fall. To ensure good structural stability of the clothesline 100 bracket during use with the clothesline, it can be made of sturdy and durable materials, such as aluminum alloy or stainless steel. Furthermore, the shape and size of the bracket housing 10 can be designed according to the overall design of the clothesline and user needs; this embodiment does not impose strict limitations or requirements in these aspects.

[0072] Specifically, the drive component 20 is movably disposed on the bracket housing 10. The drive component 20 is used to connect with the lifting assembly 90 of the clothes drying device. During the lifting and lowering process of the bracket housing 10 with the lifting assembly 90 of the clothes drying device, the drive component 20 reciprocates relative to the bracket housing 10 in a preset direction. It should be understood that the lifting assembly 90 can serve as both a medium for transmitting lifting power to the clothes drying device and a component for stabilizing the lifting and lowering movement of the clothes drying device relative to the bracket housing 10. For example, a scissor frame is a common structural form of the lifting assembly 90. The scissor frame typically consists of two scissor arms 91 and a bracket, which are shaped like the two blades of scissors and connected together by the bracket to form a telescopic and foldable structure. This structure allows the scissor frame to remain stable when the clothes drying rod 100 bears weight, while allowing the clothes drying device to move smoothly during the lifting and lowering process of the drive bracket housing 10. Of course, the lifting component 90 can also be set as other movable components with stable support functions, as long as it can improve the relative stability between the bracket housing 10 and the main unit of the clothes drying machine in actual application scenarios. This embodiment does not impose strict limitations or requirements on this. Therefore, it can be understood that in order to achieve synchronous movement between the lifting component 90 and the bracket housing 10 while ensuring that the lifting component 90 has a certain strength, the lifting component 90 needs to generate relative movement with the bracket housing 10 during the lifting and lowering movement of the bracket housing 10 relative to the main unit of the clothes drying machine. Therefore, this embodiment provides a driving component 20 on the bracket housing 10 as a medium for the movable connection between the bracket housing 10 and the lifting component 90, so that the lifting component 90 can be connected to the bracket housing 10 through the driving component 20, and at the same time, the lifting component 90 can move on the bracket housing 10 through the driving component 20.

[0073] It should be understood that this embodiment does not impose strict limitations or requirements on the direction of movement of the drive component 20 on the bracket housing 10. The movement trajectory of the drive component 20 on the bracket housing 10 can be determined specifically according to the specific structure and cooperation method of the lifting assembly 90 and the bracket housing 10.

[0074] Taking the above-mentioned lifting component 90 as an example of the scissor frame implementation, it can be understood that the scissor frame mainly serves to enhance the strength between the bracket housing 10 (clothes drying rod 100) and the main unit of the clothes drying machine. The traction component 82 used to pull the bracket housing 10 to lift relative to the main unit of the clothes drying machine can be, but is not limited to, a chain, rack and pinion, a screw lifting mechanism (such as a lead screw pair), a synchronous belt and a synchronous pulley, etc. The traction component 82 is connected to the power unit 81 of the clothes drying machine to transmit the traction force output by the power unit 81 to the bracket housing 10, thereby realizing the relative lifting of the bracket housing 10 and the main unit of the clothes drying machine.

[0075] Following the above embodiment, the telescopic component 30 included in the clothes drying rack extension bracket is telescopically disposed on the bracket housing 10. The telescopic component 30 has a drying position relatively far away from the bracket housing 10 and a storage position relatively close to the bracket housing 10 in its direction of movement. It can be understood that the telescopic component 30 is installed with the clothes drying rod 100 in the actual application scenario of the clothes drying machine. The clothes drying rod 100 can provide a corresponding hanging position for the clothes that need to be dried, so as to determine the basic drying area that the clothes drying machine can provide according to the specific structural design of the clothes drying rod 100. Similarly, this embodiment does not explicitly limit or require the specific direction of movement of the telescopic component 30 on the bracket housing 10. However, it should be noted that when the telescopic component 30 moves in a preset direction (such as horizontal or vertical) relative to the bracket housing 10, the distance between the end of the telescopic component 30 used to connect the clothes drying rod 100 and the bracket housing 10 should be greater in the drying position than in the storage position. This allows the telescopic component 30 to move the clothes drying rod 100 closer to or further away from the bracket housing 10 according to the user's needs, thereby expanding or shrinking the drying area.

[0076] In addition, in some embodiments, it is not limited to providing multiple telescopic components 30 on the bracket housing 10, and each telescopic component 30 is provided with at least one clothes drying rod 100. In this way, the clothes drying rod 100 can be expanded and folded in different directions, which can meet more different application scenarios and user needs.

[0077] As a specific structural form, the telescopic assembly 30 includes a telescopic frame, which can be understood as a rod extending in the direction of its telescopic movement relative to the bracket housing 10. The first end of the telescopic frame is kept in active engagement with the bracket housing 10, while the other end of the telescopic frame can move in the direction of approaching and away from the bracket housing 10 and is used to provide a connection position for the clothes drying rod 100 of the clothes dryer.

[0078] Furthermore, a locking mechanism 40 is provided between the bracket housing 10 and the telescopic component 30. The locking mechanism 40 is used to lock the telescopic component 30 in the drying position, so that when the telescopic component 30 moves the clothes drying rod 100 to the drying position, it can establish a relatively fixed cooperation relationship with the bracket housing 10, thereby improving the stability of the clothes drying rod extension bracket in the extended state of the drying area. This not only makes it easier for users to hang clothes on the clothes rack, but also reduces the shaking of clothes hanging on the clothes drying rod 100 during the drying process.

[0079] It is understood that there are various structures for locking the bracket housing 10 and the telescopic assembly 30. These structures may include, but are not limited to, mechanical lock structures (such as bolt locks, which consist of a bolt and a keyhole, with the bolt and keyhole respectively provided on the bracket housing 10 and the telescopic assembly 30, so that the bolt can be inserted into the keyhole to lock the two), rotary lock structures (similar to door lock structures, generally including a lock body and a rotating component, with the lock body and rotating component respectively provided on the bracket housing 10 and the telescopic assembly 30, and the two are locked by controlling the rotation of the rotating component), etc. In this embodiment, the specific structural form of the locking mechanism 40 is not specifically limited or required.

[0080] In other embodiments of the locking mechanism 40, it can also employ purely physical structures such as a snap-fit ​​structure or a wedge structure to limit the telescopic component 30 on the bracket housing 10. For ease of understanding, let's take an embodiment where the locking mechanism 40 uses a snap-fit ​​structure as an example. A snap-fit ​​structure typically consists of a snap-fit ​​body and a snap-fit ​​element. In this embodiment, a snap-fit ​​body is provided on one of the bracket housing 10 and the telescopic component 30, while a snap-fit ​​element is provided on the other. This allows the telescopic component 30 to lock into the bracket housing 10 by engaging the snap-fit ​​body with the snap-fit ​​element when it extends to the drying position. Furthermore, the snap-fit ​​element and the snap-fit ​​body can be unlocked under a certain external force, allowing the telescopic component 30 to return to its storage position after unlocking from the bracket housing 10.

[0081] Furthermore, in this embodiment, the drive component 20 is configured to trigger the locking mechanism 40 to unlock when it moves to a preset position relative to the bracket housing 10 during the linkage process with the lifting component 90. For example, when the bracket housing 10 descends and the telescopic component 30 is extended in the drying position, when the clothes dryer drives the bracket housing 10 to rise through the traction component 82, the drive component 20 moves with the lifting component 90 to a certain distance (the bracket housing 10 rises to a certain stroke), and then the drive component 20 can trigger the locking mechanism 40 to unlock, thereby allowing the telescopic component 30 to unlock from the bracket housing 10 during this process, so that the telescopic component 30 can be reset from the drying position to the storage position. When the bracket housing 10 rises to the upper limit position (stored in the main unit of the clothes dryer), the telescopic component 30 can drive the clothes drying rod 100 to move close to the bracket housing 10, satisfying the miniaturization design and storage of the clothes dryer while avoiding interference between the clothes drying rod 100 and the main unit of the clothes dryer. Furthermore, during the aforementioned process, the user only needs to control the movement of the bracket housing 10, thereby reducing the number of operation steps for the clothes drying rod 100, making the clothes drying rack easier to use and suitable for a wider range of applications and user groups. The unlocking process of the telescopic component 30 is achieved solely through mechanical transmission, making the overall structure of the clothes drying rack simpler and more reliable. This effectively reduces the overall size and weight of the clothes drying rack, improves its overall visual appeal, reduces the probability of equipment damage, enhances the stability of the clothes drying rack, and facilitates equipment maintenance.

[0082] It is understandable that in the above embodiment, since the bracket housing 10 needs to rise a certain distance relative to the main unit of the clothes dryer before the driving component 20 triggers the locking mechanism 40 to unlock the telescopic component 30 from the bracket housing 10, the bracket housing 10 has already risen a certain distance relative to the main unit of the clothes dryer when the locking mechanism 40 is triggered to unlock. This will increase the time required for the user to operate the telescopic component 30 after it is unlocked. Therefore, in order to enable the telescopic frame to automatically reset from the drying position to the storage position after unlocking, a reset mechanism (such as the second reset component 70 mentioned later) can be further provided between the telescopic frame and the bracket housing 10 to facilitate the reset of the telescopic frame.

[0083] For example, to allow the telescopic rack to return to its retracted position after unlocking, a spring reset structure can be provided between the rack housing 10 and the telescopic component 30. A compression spring or tension spring is installed between the telescopic component 30 and the rack housing 10. When the telescopic component 30 extends and is locked in the drying position by the locking mechanism 40, the spring is compressed or stretched to apply an elastic force to the telescopic component 30 to move it to the storage position. After the driving component 20 triggers the locking mechanism 40 to unlock, the spring releases energy, pushing or pulling the telescopic component 30 back to the storage position. Alternatively, the telescopic component 30 can also be reset to the storage position on the rack housing 10 by hydraulic or pneumatic means, that is, the spring in the above exemplary solution can be set as a hydraulic spring or a gas spring.

[0084] Please continue to refer to the instruction manual appendix. Figures 5-19 As a specific structural form of the locking mechanism 40, in order for the bracket housing 10 to restrict the telescopic component 30 to the drying position, the locking mechanism 40 needs to be provided with structures that can achieve locking engagement on both the bracket housing 10 and the telescopic component 30. In this embodiment, the locking mechanism 40 includes a first limiting structure 41 and a second limiting structure 42. The first limiting structure 41 is disposed on the bracket housing 10, and the second limiting structure 42 is disposed on the telescopic component 30. When the telescopic component 30 moves telescopically relative to the bracket housing 10, the second limiting structure 42 moves with the telescopic component 30 and is relatively displaced with the first limiting structure 41. In order for the first limiting structure 41 and the second limiting structure 42 to achieve locking engagement when the telescopic component 30 moves to the drying position, the first limiting structure 41 is disposed on the movement trajectory of the second limiting structure 42.

[0085] Furthermore, in order for the first limiting structure 41 and the second limiting structure 42 to be triggered by the driving component 20 after locking and engaging, thus disengaging from each other, one of the first limiting structure 41 and the second limiting structure 42 needs to have two position states: a locked position and an unlocked position. When the first limiting structure 41 and the second limiting structure 42 are in relative positions, and one of the first limiting structure 41 and the second limiting structure 42 is in the locked position, the first limiting structure 41 and the second limiting structure 42 are locked together, fixing the telescopic component 30 relative to the bracket housing 10. When one of the first limiting structure 41 and the second limiting structure 42 is in the unlocked position, there is no physical engagement between the first limiting structure 41 and the second limiting structure 42, allowing the telescopic component 30 to unlock from the bracket housing 10. During the movement of the telescopic component 30 towards the storage position, the first limiting structure 41 and the second limiting structure 42 disengage.

[0086] As can be seen from the above, the first limiting structure 41 and the second limiting structure 42 can be configured to cooperate in any way using mechanical locking and unlocking methods. For example, when the first limiting structure 41 is configured as a locking point or locking groove, the second limiting structure 42 can be configured as a locking block or locking pin that cooperates with the locking point or locking groove. Alternatively, when the first limiting structure 41 is configured as a slot, the second limiting structure 42 can be configured as a card block that is adapted to the slot. Therefore, this embodiment does not impose specific limitations or requirements on the specific structural forms of the first limiting structure 41 and the second limiting structure 42.

[0087] As can be seen from the above, when the telescopic component 30 is locked in the drying position on the bracket housing 10, the first limiting structure 41 and the second limiting structure 42 are locked together. During the process of the bracket housing 10 being driven to rise (or fall) by the clothes drying machine, the driving component 20 can trigger the first limiting structure 41 or the second limiting structure 42 (depending on whether the first limiting structure 41 or the second limiting structure 42 has the function of switching between locking and unlocking positions) when it moves to a preset position relative to the bracket housing 10, thereby disengaging the first limiting structure 41 and the second limiting structure 42 and allowing the telescopic component 30 to move from the drying position to the storage position.

[0088] Based on the above embodiments, a first reset component 43 is further provided between the first limiting structure 41 and the bracket housing 10, or between the second limiting structure 42 and the telescopic component 30. The specific location of the first reset component 43—between the first limiting structure 41 and the bracket housing 10, or between the second limiting structure 42 and the telescopic component 30—depends on whether the first limiting structure 41 has the ability to switch between a locked and unlocked position, or the second limiting structure 42 has the ability to switch between a locked and unlocked position in the actual application scenario. When the first limiting structure 41 has the ability to switch between a locked and unlocked position, the first reset component 43 is located between the first limiting structure 41 and the bracket housing 10. However, in this embodiment, as... Figure 8 , Figure 11 , Figure 16 , Figure 19 As shown, when the second limiting structure 42 has the ability to switch between locked and unlocked positions, the first reset component 43 is disposed between the second limiting structure 42 and the telescopic component 30.

[0089] Furthermore, the first reset component 43 is used to act on the first limiting structure 41 or the second limiting structure 42 according to the actual situation of the first limiting structure 41 and the second limiting structure 42, so that the first limiting structure 41 or the second limiting structure 42 tends to move towards the locked position. For example, when the second limiting structure 42 has the ability to switch between the locked position and the unlocked position, as mentioned above, the first reset component 43 acts on the second limiting structure 42, so that the second limiting structure 42 tends to move towards the locked position. In this way, when the driving component 20 moves to the preset position and triggers the locking mechanism 40, the second reset structure can overcome the force applied to it by the first reset component 43 under the action of the driving component 20, and move from the locked position to the unlocked position, thereby realizing the disengagement of the second limiting structure 42 from the first limiting structure 41.

[0090] This embodiment, by setting the locking structure as described above, including a first limiting structure 41, a second limiting structure 42, and a first reset component 43, ensures the stability of the telescopic assembly 30 on the bracket housing 10 when in the drying position, effectively preventing positional displacement caused by wind, gravity, or other external forces, and improving safety during use. Furthermore, the design of the first reset component 43 ensures that the locking mechanism 40 remains locked without the action of the driving component 20, preventing accidental unlocking and further enhancing stability and safety during user operation. It also prevents gaps between the telescopic assembly 30 and the bracket housing 10, such as those described above. Figures 5-19 The second reset component 70 shown here suddenly retracts due to accidental unlocking. The key point is that the design of the drive component 20 allows the user to easily unlock the telescopic component 30. The user only needs to manually or electrically drive the bracket housing 10 relative to the main unit of the clothes dryer by using the power unit 81 to achieve automatic unlocking of the telescopic component 30. No excessive force or complicated operation is required, which improves the convenience of use.

[0091] Based on the preliminary structural form of the locking mechanism 40 provided above, this embodiment also provides a specific structural form of the bracket housing 10, so as to protect the telescopic component 30 and the driving component 20 through the bracket housing 10, and to play a certain constraint role on the movement direction of the telescopic component 30 and the driving component 20, thereby improving the stability of the clothes drying rack extension bracket during operation.

[0092] Please refer to the instruction manual for details. Figures 5-6 , Figure 9 , Figures 12-14The bracket housing 10 has a hollow first movable part 11 inside. At least one end of the bracket housing 10 has a telescopic opening that communicates with the first movable part 11. In other words, the bracket housing 10 has a hollow cavity structure at the position where the first movable part 11 is formed. The position of the telescopic opening limits the telescopic direction of the telescopic component 30 inside the bracket housing 10. The telescopic component 30 is movably disposed inside the first movable part 11 and can extend out of the bracket housing 10 through the telescopic opening.

[0093] As can be seen from the above embodiments, the telescopic frame included in the telescopic assembly 30 can be configured as a rod structure. Therefore, in order to ensure that the bracket housing 10 can form a stable telescopic cooperation relationship with the telescopic assembly 30, the structure of the telescopic assembly 30 should match the structure of the first movable part 11 formed by the bracket housing 10. For example, in order to reduce the manufacturing difficulty and structural complexity of the clothes drying rod extension bracket, the movement trajectory of the telescopic assembly 30 in the bracket housing 10 and the movement trajectory of the driving component 20 on the bracket housing 10 are generally straight lines. Therefore, the bracket housing 10 can be processed by aluminum extrusion process, so the cross-sectional shape of the bracket housing 10 (first movable part 11) is approximately rectangular. Therefore, the cross-sectional shape of the telescopic frame included in the telescopic assembly 30 is also appropriately set as a rectangle that matches the first movable part 11, so that each wall panel of the first movable part 11 can protect and restrict the telescopic assembly 30 and play a certain guiding role.

[0094] It is understandable that the number of first movable parts 11 on the bracket housing 10, as well as the number and position of telescopic openings on the first movable parts 11, can be determined according to the specific telescopic method and structure of the telescopic assembly 30. For example, see attached... Figures 5-11 As shown, when the telescopic frames included in the telescopic assembly 30 are spaced apart within the bracket housing 10, the bracket housing 10 can correspondingly provide a plurality of first movable portions 11, and each first movable portion 11 is spaced apart and formed on each side within the bracket housing 10. Furthermore, due to the different directions of movement of each telescopic frame, the telescopic openings on each first movable portion 11 are also located at different ends of the first movable portion 11 according to the corresponding direction of movement of the telescopic frame. And as... Figures 12-19 As shown, when the telescopic frames included in the telescopic assembly 30 are arranged side by side in the bracket housing 10, the bracket housing 10 can be provided with only one first movable part 11, and the first movable part 11 can accommodate each telescopic frame included in the telescopic assembly 30. Due to the different directions of movement of each telescopic frame, multiple telescopic openings are provided on the first movable part 11.

[0095] Furthermore, a second movable part 12 is formed on one side of the bracket housing 10 located on the first movable part 11, and a partition 13 is provided between the first movable part 11 and the second movable part 12. The drive component 20 is movably disposed on the second movable part 12.

[0096] As can be seen from the above, this embodiment does not specifically limit the telescopic direction of each telescopic frame in the telescopic assembly 30. Each telescopic frame can move relative to the bracket housing 10 in a horizontal or vertical direction, but is not limited to this. In this embodiment, the extension directions of the first movable part 11 and the second movable part 12 are parallel to those of the bracket housing 10. This ensures that the movement directions of the telescopic assembly 30 and the drive component 20 are parallel, thereby maximizing the saving of space occupied by the clothesline extension bracket in other directions and facilitating the miniaturization and compact design of the clothes drying machine as a whole.

[0097] As can be seen from the above, each of the first movable parts 11 and the second movable parts 12 is separated by a partition 13. For example, in the above-mentioned appendix... Figures 5-11 When there are multiple first movable parts 11, the second movable part 12 is disposed between each of the first movable parts 11, and in the above-mentioned appendix Figures 12-19 In the case where there is only one first movable part 11, the second movable part 12 is located on one side of the first movable part 11.

[0098] According to the embodiment of the locking mechanism 40 including a first limiting structure 41, a second limiting structure 42, and a first reset component 43, the first limiting structure 41 is disposed on the partition 13. Thus, the first limiting structure 41 is located between the first movable part 11 and the second movable part 12. When the telescopic component 30 and the driving component 20 are respectively installed on the first movable part 11 and the second movable part 12, the first limiting structure 41 is located on the movement path of the telescopic component 30 and the driving component 20. This allows the first limiting component to cooperate with the second limiting structure 42 on the telescopic component 30 to lock the telescopic component 30 and the bracket housing 10. It also allows the driving component 20 to trigger the first limiting structure or the second limiting structure 42, allowing the telescopic component 30 and the bracket housing 10 to be released and unlocked. Its overall structural layout is more reasonable and compact, which not only protects and constrains the telescopic component 30 and the drive component 20 by the bracket housing 10, avoiding interference between the drive component 20 and the telescopic component 30 during relative movement, but also ensures that the drive component 20 can trigger the locking mechanism 40 to unlock the telescopic component 30 and the offline housing, thus improving both structural stability and functional stability.

[0099] In one embodiment, such as Figures 5-6 , Figure 9 , Figures 12-14As shown, the structure of the second movable part 12 in this embodiment is similar to that of the first movable part 11. That is, the second movable part 12 is also configured as a cavity structure located inside the bracket housing 10, so that the cavity wall (and partition 13) inside the bracket housing 10 plays a role in protecting the drive component 20 and constraining its movement direction. However, it should be noted that since the drive component 20 needs to be connected to the lifting assembly 90 of the clothes drying rack, the bracket housing 10 located on the second movable part 12 needs to have a clearance opening that communicates with the second movable part 12, so that the end of the telescopic assembly 30 used to connect to the drive component 20 can enter the second movable part 12 through the clearance opening and connect with the drive component 20.

[0100] Please continue to refer to the instruction manual appendix. Figures 5-19 As a specific structural form of the aforementioned locking structure, the first limiting structure 41 is configured as a locking hole penetrating both sides of the partition 13. The opposite ends of the locking hole are respectively connected to the first movable part 11 and the second movable part 12, so that the driving component 20 and the second limiting structure 42 provided on the telescopic structure can be linked together in a state where they are opposite each other through the locking hole. Correspondingly, the second limiting structure 42 is configured as a locking pin, which is telescopically provided on the telescopic component 30. The first reset component 43 is an elastic element provided on the telescopic component 30. The elastic element is installed between the telescopic component 30 and the locking pin, so that when the telescopic component 30 is relatively stationary, it continuously acts on the locking pin, so that the locking pin has a tendency to extend out of the telescopic component 30 (move towards the locking position).

[0101] Through the above implementation, when the telescopic component 30 is in the drying position, the locking pin, which serves as the second limiting joint, can be reset from the unlocked position to the locked position under the action of the elastic element of the first reset component 43 of the seat, thereby inserting into the locking hole, which serves as the first limiting structure 41, to lock the telescopic component and the bracket housing 10. When the clothes dryer drives the bracket housing 10 to rise (or fall, which is not limited in this embodiment), the drive component 20 moves from the direction away from the locking hole to the direction closer to the locking hole, and when it moves to the locking hole, it abuts against the locking pin, so that the locking pin can retract towards the telescopic component 30 in the direction of disengaging from the locking hole under the action of the elastic force of the elastic element, until the locking pin is completely disengaged from the locking hole (the locking pin moves to the unlocked position), thereby unlocking the telescopic component 30 and the bracket housing 10.

[0102] In one embodiment, such as Figure 11 , Figure 19As shown, when the telescopic component 30 is in the drying position and the locking pin is in the locked position, the locking pin passes through the locking hole from the first movable part 11 to the second movable part 12. The end of the locking pin protrudes from the partition 13 and is away from the side of the telescopic component 30, providing sufficient abutment position for the drive component 20. This also eliminates the need to set a drive structure protruding towards the locking hole on the drive component 20, simplifying the processing technology of the locking mechanism 40 and making its structure simpler.

[0103] Furthermore, a guide slope 421 is formed at one end of the locking pin that passes through the locking hole. When the drive member 20 is in a position away from the locking hole, a top abutment 21 is formed on the side of the drive member 20 near the partition 13 for moving to the unlock position by abutting the locking pin through the guide slope 421. The guide slope 421 is inclined toward the top abutment 21 so that when the drive member 20 approaches the locking hole and abuts the locking pin, the drive member 20 can abut the guide slope 421 through the top abutment 21 to apply a locking force to the telescopic assembly 30 to the locking pin. This embodiment sets the side of the locking pin that the drive component 20 abuts against as a guide slope 421, which can minimize the resistance and friction generated when the drive component 20 contacts and abuts against the locking pin. Furthermore, when the abutting top 21 acts on the locking pin through the guide slope 421, the guide slope 421 can convert the force in the direction of movement of the drive component 20 into a driving force along the extension direction of the locking pin. This allows the locking pin to retract into the telescopic assembly 30 and disengage from the locking hole more easily under the action of the drive component 20, reducing the burden on the lifting assembly 90 and the drive component 20, and making the unlocking process of the telescopic assembly 30 smoother.

[0104] It should be noted that, with the above settings, when the locking pin is in the unlocked position, the end of the locking pin does not necessarily need to be completely disengaged from the locking hole. It is sufficient to ensure that the lower end of the guide slope 421 is outside the edge of the locking hole. In this way, when the locking hole is in the unlocked position, when the telescopic component 30 moves from the drying position to the storage position, the guide slope 421 can abut against the edge of the locking hole, thereby applying a locking force to the locking pin in the direction of the telescopic component 30 through the edge of the locking hole. Finally, the locking pin can be further retracted into the telescopic component 30 under the action of the locking hole until the higher end of the guide slope 421 disengages from the edge of the locking hole, thus achieving complete disengagement of the locking pin from the locking hole and completing the release of the telescopic component 30 and the bracket housing 10 by the locking mechanism 40. This configuration ensures that the drive component 20 has a simple structure. There is no need to set a trigger structure protruding into the locking hole on the drive component 20. It only needs to push the locking pin against one end of the telescopic component 30 so that the guide slope 421 at the end of the locking pin is disengaged from the locking hole, making the locking mechanism 40 simpler and more compact.

[0105] Based on the structural foundation provided by the above embodiments, this embodiment takes a set of telescopic components 30 including a first telescopic frame 31 and a second telescopic frame 32 as an example. Furthermore, both the first telescopic frame 31 and the second telescopic frame 32 can move back and forth synchronously between the drying position and the storage position.

[0106] like Figures 5-11 As shown, in the embodiment where the first telescopic frame 31 and the second telescopic frame 32 are respectively placed on both sides of the bracket housing 10, that is, in the embodiment where the bracket housing 10 includes two first movable parts 11, the drive component 20 is also correspondingly set to two, and the first telescopic frame 31 and the second telescopic frame 32 are respectively connected to the drive component 20 through the first transmission assembly 50.

[0107] like Figures 12-19 As shown, when the first telescopic frame 31 and the second telescopic frame 32 are arranged side by side in the bracket housing 10, that is, in the embodiment where the bracket housing 10 includes only one first movable part 11, the first telescopic frame 31 and the drive component 20 are connected by a first transmission assembly 50, and the first telescopic frame 31 and the second telescopic frame 32 are connected by a second transmission assembly 60.

[0108] Based on the above, the telescopic component 30 also establishes a linkage with the drive component 20 in the actual application scenario of the clothes drying equipment. This allows the drive component 20 to move with the lifting component 90 to satisfy the unlocking function of the telescopic component 30, while also enabling the telescopic component 30 to extend and retract within the bracket housing 10 according to the movement direction of the drive component 20. This ensures that the telescopic component 30 can move accordingly between the drying position and the storage position during the lifting and lowering of the bracket housing 10. This linkage mechanism can be established through transmission structures such as gears, chains, transmission belts, and sliders. Thus, the power generated by the lifting component 90 moving relative to the clothes drying machine main unit through the bracket housing 10 can both unlock the telescopic component 30 and be converted into the telescopic movement of the telescopic component 30 on the bracket housing 10.

[0109] For example, during the descent of the bracket housing 10 relative to the main unit of the clothes drying device, the telescopic component 30, driven by the drive component 20 and the first transmission component 50, moves from the storage position to the drying position, providing a larger drying area for the clothes to be dried. This not only increases the drying capacity of the clothes drying device but also widens the spacing between the clothes, thereby improving the drying effect. Conversely, during the ascent of the bracket housing 10 relative to the main unit of the clothes drying device, the telescopic component 30 moves from the drying position to the storage position, ensuring that the drying rod is positioned in the storage position provided by the clothes drying device along with the bracket housing 10, maintaining the integrity and aesthetics of the device.

[0110] As can be seen from the above-described embodiment, the first telescopic frame 31 and the second telescopic frame 32 can be controlled either by two independently moving drive components 20 or by a linkage between the first telescopic frame 31 and the second telescopic frame 32 to achieve synchronous control, so as to meet different usage requirements.

[0111] Taking the above-mentioned implementation method of setting the lifting component 90 of the clothes drying rack as a scissor rack as an example, combined with the attached... Figures 2-3 The scissor-mounted clothes dryer works by using the folding of the scissor arms 91 to raise and lower the outer shell 10 on the clothes dryer. When the clothes dryer needs the outer shell 10 to rise, the two hinged scissor arms 91 expand outwards, gradually increasing the upward and downward angles between them, and decreasing the distance between the two ends of the scissor arms 91, thus gradually increasing the height of the outer shell 10. Conversely, when the clothes dryer needs the outer shell 10 to fall, the two hinged scissor arms 91 narrow inwards, gradually decreasing the upward and downward angles between them, and increasing the distance between the two ends of the scissor arms 91, thus gradually decreasing the height of the outer shell 10.

[0112] According to the design requirements of the clothes drying equipment, multiple scissor frames can be installed between the bracket housing 10 and the main unit of the clothes drying machine, so that the height position of the bracket housing 10 in different states can be determined according to the number of scissor frames.

[0113] Therefore, to ensure that the bracket housing 10 can be driven by the scissor frame, which serves as the lifting assembly 90, the two scissor arms 91 at both ends of the scissor frame that are connected to the bracket housing 10 need to be in a sliding connection manner to avoid interference between the two hinged scissor arms 91 and the connection structure between them and the bracket housing 10 when adjusting their angle. In the embodiment described above, the clothesline 100 bracket also includes a drive component 20. In this embodiment, the drive component 20 acts as a slider and is rotatably connected to the scissor arms 91 in the scissor frame. This allows the scissor arms 91 to form a sliding connection with the bracket housing 10 through the drive component 20, thus achieving the effect of linkage between the drive component 20 and the lifting assembly 90.

[0114] As mentioned above, during the upward movement of the bracket housing 10, the two hinged scissor arms 91 in the scissor frame will move in the unfolding direction. However, in the product design requirements of the clothes drying rack, during the upward movement of the bracket housing 10, the first telescopic frame 31 and the second telescopic frame 32 need to move in the retracting direction close to the bracket housing 10. Therefore, in this embodiment, the movement direction of the driving component 20 is opposite to the movement direction of the first telescopic frame 31 or the second telescopic frame 32, depending on whether the driving component 20 is specifically used to drive the first telescopic frame 31 or the second telescopic frame 32.

[0115] Specifically, in the embodiment where there are two drive components 20, and the two drive components 20 are respectively used to control the movement of the first telescopic frame 31 and the second telescopic frame 32 through the two first transmission components 50, the drive component 20 is configured to move in the opposite direction to the corresponding first telescopic frame 31 or second telescopic frame 32. In the embodiment where only one drive component 20 is used to control the movement of the first telescopic frame 31 through the first transmission component 50, the drive component 20 moves in the opposite direction to the first telescopic frame 31.

[0116] Please refer to the instruction manual attached. Figures 5-19 The first transmission component 50 includes a first rack 51, a first transmission gear 52, and a second rack 53. The first rack 51 is connected to the drive component 20. In some embodiments, the first rack 51 can move synchronously with the drive component 20 in the same direction. In other embodiments, the drive component 20 can only drive the first rack 51 to move in a single direction, and when the drive component 20 moves in the opposite direction, the first rack 51 disengages from the drive component 20. This embodiment does not have strict limitations or requirements on the extension direction of the first rack 51. However, in some embodiments, to fit the shape design of the bracket housing 10 and improve the space utilization of the first transmission component 50 on the bracket housing 10, and to make the size and structure of the bracket housing 10 sufficiently compact on the clothes dryer, the first rack 51 can be configured to extend along the movement direction of the drive component 20. The first transmission gear 52 is rotatably mounted on the second movable part 12 of the bracket housing 10 and meshes with the first rack 51. Thus, in one embodiment, under the drive of the lifting assembly 90 (scissor frame), the first rack 51 moves in the same direction as the drive component 20, while the first transmission gear 52 rotates forward or backward on the bracket housing 10 according to the direction of movement of the drive component 20. The second rack 53 is fixedly mounted on the first telescopic frame 31 or the second telescopic frame 32 (depending on whether the drive component 20 is used to control the first telescopic frame 31 or the second telescopic frame 32) and meshes with the second transmission gear 62.

[0117] Based on the above embodiments, in order to achieve the effect of increasing the transmission ratio between the drive component 20 and the first telescopic frame 31 or the second telescopic frame 32, such as Figures 5-11 As shown, the first transmission gear 52 includes a first gear 521 and a second gear 522. The first gear 521 and the second gear 522 are coaxially connected. The first gear 521 is smaller than the second gear 522, and the first gear 521 meshes with the first rack 51, while the second gear 522 meshes with the second rack 53, thereby increasing the transmission ratio. Alternatively, the first gear 521 and the second gear 522 can also be meshed to achieve the effect of a smaller gear driving a larger gear, increasing the transmission ratio. For example, as shown... Figures 12-19As shown, the first gear 521 and the second gear 522 are spaced apart on the bracket housing 10, and they cooperate with each other through transmission components such as a transmission belt or chain.

[0118] The first transmission component 50 of this embodiment establishes a linkage between the drive component 20 and the first telescopic frame 31 or the second telescopic frame 32 by adopting the aforementioned gear and rack transmission method. This effectively improves the load-bearing capacity and accuracy of the clothes drying rod 100 bracket in the application of the clothes drying machine. It is understood that gear and rack transmission has a large load-bearing capacity and can withstand large loads and torques. At the same time, gear and rack transmission has high transmission accuracy. Therefore, this not only improves the load-bearing capacity of the clothes drying rod 100 for drying clothes, but also ensures the movement accuracy between the telescopic component 30 and the bracket housing 10 during the linkage with the lifting component 90. This achieves the effect of accurately switching the state of the telescopic component 30 according to different states of the clothes drying equipment, thereby improving the reliability and stability of the clothes drying equipment.

[0119] It is worth mentioning that, such as Figures 5-11 As shown, in the embodiment where there are two drive components 20, and the two drive components drive the first telescopic frame 31 and the second telescopic frame 32 respectively through two independent first transmission components 50, when the first telescopic frame 31 and the second telescopic frame 32 are respectively arranged on opposite sides of the bracket housing 10, the two drive components 20 and the first transmission components 50 are also arranged on both sides of the bracket housing 10 in an almost mirror-like manner. Furthermore, based on the second movable part 12 being located between each of the first movable parts 11, the two drive components 20 and the two first transmission components 50 are both located between the first telescopic frame 31 and the second telescopic frame 32. The two drive components 20 are connected to the two scissor arms 91 of the scissor frame respectively, so that the first telescopic frame 31 and the second telescopic frame 32 are driven by the two drive components 20 and the first drive components respectively.

[0120] In the case where the first telescopic frame 31 and the second telescopic frame 32 are connected by the second transmission assembly 60, this embodiment takes the example of the first telescopic frame 31 being connected to the second telescopic frame 32 via the first transmission assembly 50. Of course, in other embodiments, the drive component 20 may also be connected to the second telescopic frame 32 via the first transmission assembly 50. Please continue to refer to the appendix of the specification. Figures 12-19As a specific structural form of the aforementioned second transmission component 60, taking the embodiment where the first telescopic frame 31 and the second telescopic frame 32 move in opposite directions along the horizontal direction to achieve synchronous switching of position states as an example, the second transmission component 60 includes a third rack 61, a second transmission gear 62, and a fourth rack 63 in a set of telescopic components 30. The third rack 61 is fixedly mounted on the first telescopic frame 31, enabling it to move synchronously with the first telescopic frame 31. The second transmission gear 62 is rotatably mounted on the first movable part 11 of the bracket housing 10 and meshes with the third rack 61, allowing the second transmission gear 62 to rotate forward or backward on the bracket housing 10 according to the direction of movement of the third rack 61 (first telescopic frame 31). The fourth rack 63 is fixedly mounted on the second telescopic frame 32 and meshes with the second transmission gear 62, thereby causing the fourth rack 63 to drive the second telescopic frame 32 to move in the opposite direction to the third rack 61 according to the rotation of the second transmission gear 62.

[0121] It is understood that in this embodiment, there is a certain gap between the first telescopic frame 31 and the second telescopic frame 32, and the sides of the two that are close to each other are respectively provided with a third rack 61 and a fourth rack 63. The gap between the first telescopic frame 31 and the second telescopic frame 32 allows the second transmission gear 62 to be accommodated, and when the second transmission gear 62 is accommodated, its opposite sides can mesh with the third rack 61 and the fourth rack 63 respectively, so that the first telescopic frame 31 and the second telescopic frame 32 establish a synchronous transmission relationship.

[0122] As can be understood from the above structural form, similar gear and rack transmission methods are used between adjacent first telescopic frames 31 and second telescopic frames 32, as well as between adjacent first telescopic frames 31 and drive components 20. This not only ensures that the first telescopic frames 31 and second telescopic frames 32 can maintain a high load-bearing capacity to ensure that the clothes drying rack 100 has a strong load-bearing capacity, but also allows the first telescopic frames 31 and second telescopic frames 32 to maintain a high transmission accuracy during linkage, thereby realizing synchronous telescopic movement between the first telescopic frames 31 and second telescopic frames 32, allowing the drying area of ​​the clothes drying rack to be effectively expanded and contracted.

[0123] As can be seen from the above, in one embodiment, a second reset component 70 is further provided between the bracket housing 10 and the first telescopic frame 31 and / or the second telescopic frame 32. Exemplarily, when the first telescopic frame 31 and the second telescopic frame 32 are driven by two independent drive components 20 and the first transmission assembly 50 respectively, the second reset component 70 is provided between the first telescopic frame 31 and the bracket housing 10, and between the second telescopic frame 32 and the bracket housing 10. When the first telescopic frame 31 and the second telescopic frame 32 are connected by a second transmission assembly 60, the second reset component 70 can be provided between the first telescopic frame 31 and the bracket housing 10, or the second reset component 70 can be provided between the second telescopic frame 32 and the bracket housing 10.

[0124] The second reset component 70 is used to continuously apply a force to the telescopic component 30 to move it toward the storage position, so that after the drive component 20 triggers the locking mechanism 40 to unlock, the telescopic component 30 can be reset from the drying position to the storage position under the action of the second reset component 70.

[0125] Taking the example of the drive component 20 controlling the first telescopic frame 31 via the first transmission assembly 50 (the same applies to the implementation of the drive component 20 controlling the second telescopic frame 32 via the first transmission assembly 50), the drive component 20 abuts against the first transmission assembly 50 along the first direction. During the movement of the drive component 20 along the first direction, the drive component 20 can drive the first telescopic frame 31 from the storage position to the drying position via the first transmission assembly 50. For example, to facilitate understanding of this embodiment, this embodiment defines the direction of movement of the drive component 20 relative to the bracket housing 10 during the descent as the first direction, and the direction of movement of the drive component 20 relative to the bracket housing 10 during the ascent as the second direction; that is, the first direction and the second direction are opposite. Thus, when the bracket housing 10 descends relative to the main unit of the clothes dryer, the drive component 20 (driven by the lifting assembly 90) moves along the first direction, and during this process, it drives the first drive assembly (the first rack 51 in it) to move synchronously in a pushing manner, achieving the effect of driving the first telescopic frame 31 to move towards the drying position. During the process of the bracket housing 10 rising relative to the main unit of the clothes drying machine, the drive component 20 (driven by the lifting component 90) moves in the second direction. At this time, the drive component 20 will not have a transmission relationship with the first transmission component 50 (the first rack 51 in it). Without the action of other external forces, the drive component 20 will gradually disengage from the first transmission component as it moves in the second direction.

[0126] As can be seen from the above embodiments, the first transmission component 50 (first rack 51) does not necessarily need to completely follow the movement of the drive component 20. In this embodiment, no additional connection structure is required between the drive component 20 and the first transmission component 50. The movement of the drive component 20 in the first direction can move the first telescopic frame 31 and the second telescopic frame 32 to the drying position by abutting against the first transmission component 50. When the drive component 20 moves in the second direction, the first telescopic frame 31 (or the second telescopic frame 32) and the first transmission component 50 can be kept abutting against the drive component 20 in the second direction under the action of the second reset component 70, so that the first telescopic frame 31 (or the second telescopic frame 32) moves to the storage position according to the movement of the drive component 20. The structure between the two is simplified, thereby reducing the complexity of the telescopic bracket structure and further reducing its production and assembly difficulty. Fewer material parts and a simpler mating structure can also reduce the size of the bracket shell 10, which is beneficial to the miniaturization design requirements of the clothes drying equipment.

[0127] In practical applications, the second reset component 70 may, but is not limited to, use tension springs, compression springs, torsion springs, bending springs, constant force springs, etc. Furthermore, based on the above types, it may, but is not limited to, further use helical springs, leaf springs, worm springs, disc springs, ring springs, gas springs, rubber springs, etc. This embodiment does not impose strict limitations or requirements on this.

[0128] Please refer to the instruction manual attached. Figures 1-4 The present invention also provides a clothes drying rack, which includes a main unit, wherein the main unit further includes a main unit housing 80. The main unit housing 80 serves as the supporting foundation of the clothes drying rack, and its interior can form sufficient space to accommodate a telescopic bracket and related components. A power unit 81 is connected to the main unit housing 80. It is understood that, depending on the type of clothes drying rack, the power unit 81 can be configured to be electrically driven or manually driven. For example, in an embodiment where the clothes drying rack is electric, the power unit 81 can be a motor; in an embodiment where the clothes drying rack is manual, the power unit 81 can be a hand crank, etc. In embodiments where a power unit 81 requiring manual operation, such as a hand crank, is used, the power unit 81 can be located outside the main unit housing 80 for user convenience.

[0129] In this embodiment, the clothes drying machine also includes a lifting assembly 90 and a clothes drying rod extension bracket as provided in any of the above embodiments. The first end of the lifting assembly 90 is installed on the main unit housing 80, and the second end of the lifting assembly 90 is movably installed on the bracket housing 10 through the drive component 20. Furthermore, the bracket housing 10 is also connected to the power unit 81 through a traction component 82 (such as a steel wire rope, transmission belt, etc.). A clothes drying rod 100 is provided on the telescopic assembly 30.

[0130] Understandably, the length and shape of the clothes drying rack 100 can be selected according to different needs to meet the requirements of different usage scenarios.

[0131] Furthermore, two clothes drying rod 100 brackets, each connected to the main housing 80 via lifting components 90, can be installed near both ends of the clothes drying rack to further improve the structural stability of the clothes drying rod 100 on the clothes drying rack. The two ends of the clothes drying rod 100 installed on the clothes drying rod 100 brackets can be connected to the telescopic components 30 on the two clothes drying rod 100 brackets respectively. The two ends of the clothes drying rod 100 can move synchronously during the movement of the two telescopic components 30 relative to the main housing 80, so as to achieve the effect of expanding or narrowing the drying area, and correspondingly improve the clothes drying rack's load-bearing capacity.

[0132] It is also worth mentioning that the clothes drying rack can be equipped with appropriate limit devices and sensors to monitor the range of motion of the lifting assembly 90 or the bracket housing 10, so as to prevent the telescopic assembly 30 from being damaged due to excessive extension and retraction, and to suspend the bracket housing 10 at any height.

[0133] Please continue to refer to the appendix. Figures 1-4 This clothes drying rack has the following features: Figure 3 The descent state shown, such as Figure 1 The rising state shown and as Figure 4 The drying states are shown, in which the height of the bracket housing 10 increases sequentially from the lowering state, the drying state, and the rising state of the clothes dryer. During the switching between the lowering state and the drying state, the telescopic component 30 inside the bracket housing 10 is always in the drying position, so that when clothes are hanging on the clothes dryer, the telescopic component 30 will not drive the clothes drying rod 100 to retract, ensuring the drying effect of the clothes. When the clothes dryer switches from the drying state to the rising state, the drive component 20 triggers the locking structure, so that the telescopic component 30 (driven by the second reset component 70) resets from the drying position to the retracted position, ensuring that both the bracket housing 10 and the clothes drying rod 100 can be retracted into the main housing 80 of the clothes dryer.

[0134] It is understandable that the switching between different position states of the clothes drying rack can be achieved through the aforementioned limit device and sensor.
