Description

Technical Field

[0001] This utility model relates to an electric clothes drying rack, and more specifically, to a clothes drying rack main assembly structure and an exposed electric clothes drying rack. Background Technology

[0002] Electric clothes drying racks can be categorized into two types based on their installation method: concealed and exposed. They can also be classified by usage scenario or the number of drying rods, such as single-rod, double-rod, and four-rod configurations. Furthermore, they can be classified by the way the drying rods are folded down, such as concealed and non-concealed. Exposed clothes drying racks are those directly installed on the ceiling of a balcony. Their lifting drive module and controller module are housed within the outer casing, making them more suitable for balconies without a suspended ceiling.

[0003] Currently, most surface-mounted clothes drying racks use an assembly structure or an open bottom structure for the main unit casing to facilitate the installation of internal components such as the lifting drive module and controller module. Assembled main unit casings: such as the "A kind of exposed concealed clothes drying rack" disclosed in Chinese Patent Publication No. CN218861156U (publication date: April 14, 2023), the "A kind of concealed clothes drying rack" disclosed in Chinese Patent Publication No. CN219547347U (publication date: August 18, 2023), and the "A kind of exposed concealed single pole multi-functional clothes drying rack" disclosed in Chinese Patent Publication No. CN222594376U (publication date: March 11, 2025), etc. The main unit casing of this type of clothes drying rack adopts a top plate assembly structure, which allows for the installation of various components from the top, making the main unit simple and convenient to manufacture. However, the assembled structure is prone to assembly errors, affecting the appearance and movement accuracy of the clothes drying rack. It also requires the use of more screws for tightening, making the assembly operation more cumbersome. In addition, the overall structural strength of the casing is relatively poor, and it is prone to deformation after long-term use. Main unit casing with an open bottom: such as "Electric clothes drying rack and its main unit" disclosed in Chinese Patent Publication No. CN214245002U (publication date: September 21, 2021), "A clothes drying rack main unit and electric clothes drying rack" disclosed in Chinese Patent Publication No. CN115161970A (publication date: October 11, 2022), and "A single-pole external clothes drying rack" disclosed in Chinese Patent Publication No. CN220246491 (publication date: December 26, 2023), etc. The main unit casing of this type of clothes drying rack is mostly in the shape of an inverted "U" sheet metal structure with an open bottom, which allows for the installation of various components from the bottom of the casing. The casing mainly serves to cover the internal components. However, the structural strength of the main unit casing of this type is relatively poor, and it is easy to deform. In addition, for concealed clothes drying racks, sometimes an additional bottom cover is required, making the assembly operation more cumbersome. Summary of the Invention

[0043] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0044] [Example]

[0045] Combination Figures 1 to 4 as well as Figure 7 and Figure 9 As shown, this embodiment of a clothes drying rack main unit assembly structure includes a housing 1, a lifting drive module 2, and a controller module 3, both of which are installed inside the housing 1. Unlike existing clothes drying rack main units, in this embodiment, the housing 1 is made of profile material, and the housing 1 has a mounting cavity 1a that is closed on four sides and open at both ends, as shown... Figure 6 As shown, the outer shell 1 of this profile structure has higher overall structural strength, does not deform after long-term use, and has no assembly errors like those of assembled shells. This results in better product consistency and higher dimensional accuracy for the clothes drying rack main unit. Figure 7As shown, the lifting drive module 2 and the controller module 3 are connected together to form a single component, and are inserted into the outer casing 1 from one end of the mounting cavity 1a. The lifting drive module 2 and the controller module 3 are respectively fixedly connected to the top plate 1-1 of the outer casing 1 by screws. The clothes drying rack main unit assembly structure of this embodiment takes into account the structural strength, dimensional accuracy, and ease of assembly of the main unit, resulting in better overall integrity of the clothes drying rack main unit, making it less prone to deformation, and reducing the number of assembly screws, thus improving assembly efficiency.

[0046] Specifically, such as Figure 9 As shown, in this embodiment, the adjacent ends of the lifting drive module 2 and the controller module 3 are provided with a first connecting ear 2-2, and the adjacent ends of the controller module 3 and the lifting drive module 2 are provided with a second connecting ear 3-2. The first connecting ear 2-2 and the second connecting ear 3-2 are opposite each other and are fixedly connected by screws, making the lifting drive module 2 and the controller module 3 a whole. This facilitates the quick positioning of the lifting drive module 2 and the controller module 3 within the housing 1, making assembly more convenient. The use of a two-connecting-ear structure makes it easy to form on the lifting drive module 2 and the controller module 3, and the connection is firm and reliable.

[0047] Reference Figure 8 and Figure 9 As shown, in this embodiment, the top of the lifting drive module 2 has a pre-reserved or existing screw hole to form a drive module screw hole 2-1. The top plate 1-1 of the outer casing 1 has a drive module fixing hole 1-1a corresponding to the drive module screw hole 2-1. The lifting drive module 2 and the top plate 1-1 are fixedly connected by screws that pass through the drive module fixing hole 1-1a and are screwed into the drive module screw hole 2-1. The top of the controller module 3 has a pre-reserved control module screw hole 3-5. The top plate 1-1 of the outer casing 1 has a control module fixing hole 1-1c corresponding to the control module screw hole 3-5. The controller module 3 and the top plate 1-1 are fixedly connected by screws that pass through the control module fixing hole 1-1c and are screwed into the control module screw hole 3-5. Using screws to lock and fix the module from the top of the top plate 1-1 is simple and convenient. Compared with the assembled main casing, fewer screws are required, resulting in less assembly work and higher production efficiency. Furthermore, as... Figures 2 to 4 As shown, the lifting drive module 2 and the controller module 3 are arranged sequentially along the length of the housing 1, and the controller module 3 is offset along the width of the housing 1 towards the side away from the cable outlet 2a of the lifting drive module 2. This ensures that the cable outlet of the lifting drive module 2 is not disturbed and also helps to reduce the height of the main unit housing. The screw holes 3-5 of the control module are located at the end away from the lifting drive module 2, making the fixing of the controller module 3 more secure. Figure 7As shown, during the specific assembly, the lifting drive module 2 and the controller module 3 are first connected together with screws. Then, the lifting drive module 2 and the controller module 3 are sent into the mounting cavity 1a from one end of the housing 1. The positions of the lifting drive module 2 and the controller module 3 in the mounting cavity 1a are adjusted appropriately so that the corresponding screw holes correspond to the positions of the fixing holes. The screws are then screwed in to fix them.

[0048] Reference Figures 8 to 11 As shown, in this embodiment, the controller module 3 also has a power connection slot 3-3, and a power interface 1-1b corresponding to the position of the power connection slot 3-3 is provided on the top plate 1-1 of the housing 1. The power cable can be connected through the power interface 1-1b. To ensure the stability of the circuit connection, a wire clamp 3-1 for fixing the power cable 3-6a of the plug 3-6 is also provided in the power connection slot 3-3. The wire clamp 3-1 can effectively fix the power cable and improve the reliability of the power connection. To facilitate the routing of the power cable, a cable guide groove 1c is also provided on the top of the housing 1 above the top plate 1-1. The power cable can be located in the cable guide groove 1c, ensuring that the main unit can perfectly fit against the ceiling. Figures 9 to 11 As shown, a grounding positioning groove 3-4 is provided on the top side of the power connection groove 3-3. The grounding positioning groove 3-4 has a control module screw hole 3-5. The plug 3-6 has a grounding piece 3-6b that can be installed in the grounding positioning groove 3-4. The grounding piece 3-6b is engaged with the outer shell 1 by screwing the screw into the corresponding control module screw hole 3-5, which cleverly realizes the grounding connection of the power supply. The grounding stability is good and the assembly is convenient. In specific assembly, when the power connection groove 3-3 corresponds to the power interface 1-1b, the grounding piece 3-6b is inserted into the grounding positioning groove 3-4, so that the through hole on the grounding piece 3-6b is aligned with the control module screw hole 3-5 on the grounding positioning groove 3-4. Then, the screw is screwed in from the top of the top plate 1-1 for fixation. This realizes the connection between the top plate 1-1 and the controller module 3, and at the same time realizes the grounding connection between the grounding piece 3-6b and the top plate 1-1. The assembly is simple and convenient. Specifically, in this embodiment, the lower part of the aforementioned wire clamping base 3-1 has a wire clamping part 3-1a, which is connected to the bottom of the power connection groove 3-3 by screws. Both the wire clamping part 3-1a and the bottom of the power connection groove 3-3 have wire clamping grooves with a semi-circular cross-section. After the wire clamping part 3-1a is fixed to the bottom of the power connection groove 3-3, a complete wire groove structure is formed, and the power cord 3-6a is located within this wire groove and is clamped and fixed. The upper part of the wire clamping base 3-1 has a ground wire cover 3-1b covering the plug 3-6, which can reduce dust entering the host and ensure the long-term operational stability of the host. The ground wire cover 3-1b can also cover part of the grounding plate 3-6b, and a grounding mark is provided on the ground wire cover 3-1b to remind the user to ground at this location.

[0049] Similar to the main unit of existing clothes drying racks, brackets 4 are installed at both ends of the outer casing 1. Pulleys 5 are mounted on the brackets 4, and end caps 6 are installed at both ends of the outer casing 1. The pulleys 5 facilitate the guidance and steering of the wire rope. The brackets 4, as the main load-bearing components, can be made of sheet metal and can be used for hoisting the main unit, facilitating the installation of the clothes drying rack. The end caps 6 are decorative end pieces that can be fixedly connected to the ends of the outer casing 1 using a snap-fit ​​structure.

[0050] like Figure 4 As shown, the bottom of the outer casing 1 has an open-bottomed drying rod receiving groove 1b, which allows for the storage and concealment of the drying rod. After storage, the bottom surface of the drying rod is flush with or nearly flush with the bottom surface of the main unit. The height H2 of the drying rod receiving groove 1b is preferably 2.8–3.4 cm, and the width W2 is preferably 2.6 cm–3.2 cm, ensuring the size and strength of the drying rod, meeting both the hanging space requirements of the clothes hanger and the load-bearing strength requirements of the drying rod. Furthermore, the maximum height H1 of the outer casing 1 is preferably 6.8 cm–8.8 cm, and the maximum width W1 is preferably 6.5 cm–8.5 cm, making the overall size of the main unit more compact, the size proportions more harmonious, and the overall appearance more aesthetically pleasing after installation. One or both sides of the drying rod receiving groove 1b also have a lighting cavity 1d. The top of the lighting cavity 1d has a "T"-shaped light strip slot 1-2 for installing light strips. The light strip can be inserted from one end of the light strip slot 1-2, making installation convenient and quick; Figure 5 As shown, the bottom of the lighting cavity 1d is provided with snap-fit ​​ribs 1-4 on both sides, and the bottom surface of the lighting cavity 1d is equipped with a lampshade 1-3. The lampshade 1-3 has "n"-shaped slots 1-3a on both sides that are inserted and matched with the snap-fit ​​ribs 1-4. The lampshade 1-3 can also be inserted into the bottom of the lighting cavity 1d along the length of the snap-fit ​​ribs 1-4, and the installation is firm and reliable, which can effectively solve the problem of existing lampshade panels being easy to fall off.

[0051] This embodiment also discloses a surface-mounted electric clothes drying rack. The surface-mounted electric clothes drying rack includes a main unit and a drying rod assembly connected to the main unit. The main unit adopts the aforementioned clothes drying rack main unit assembly structure. The drying rod assembly is connected to a steel wire rope 2b extending from the lifting drive module 2. Specifically, a steel wire rope 2b extends from each end of the lifting drive module 2, and each steel wire rope 2b passes over a pulley 5 at its corresponding end and connects to the end of the drying rod assembly, keeping the drying rod assembly in a horizontally suspended state. The controller module 3 controls the raising and lowering movement of the steel wire ropes in the lifting drive module 2 and the opening and closing of the light strip, thereby controlling the descent or elevation of the drying rod assembly. When the drying rod assembly is retracted to its highest position, it can be stored in the drying rod receiving slot 1b. This surface-mounted electric clothes drying rack has strong overall integrity and good compactness, greatly improving its quality and grade.
