Description

Technical Field

[0001] The utility model relates to an electric clothes drying machine, in particular to a telescopic bracket folding height optimization system of the electric clothes drying machine. Background Art

[0002] In modern home life, a clothes drying rack is not only an essential tool for drying clothes, but its structural design also directly impacts ease of use, space efficiency, and overall home aesthetics. Clothes drying rack designs have evolved from simple fixed designs to complex, intelligent ones. The scissor rack structure, for its scalability and stability, is widely used in various clothes drying rack designs. Using a series of interlocking rods, the scissor rack allows the clothes drying rack to be expanded and collapsed. Its design must balance space usage, load-bearing capacity, and ease of use.

[0003] A patent for a clothes drying machine with good concealment effect, with authorization announcement number CN218666805U, discloses that a scissors rack is connected between an upper slot opened on the lower side of an upper component at a recessed position and a lower slot opened on the lower side of a rod seat; when the clothes drying machine is in the storage state, the lower component enters the rectangular opening; the rod seat rises to the recessed position, and the scissors rack is retracted into a hidden channel formed by the connection of the upper and lower slots.

[0004] In such a structure, in order to make the clothes drying machine thinner and more compact, the height of the scissor rack after folding should be as small as possible. Therefore, clothes drying machine manufacturers continuously optimize the design of the clothes drying rack scissor rack to adapt to user needs and market changes.

[0005] The patent titled "A scissor rack with stackable adjacent scissor blades for a clothes drying rack" (application number: 201820459281.0) discloses a scissor rack with stackable adjacent scissor blades for a clothes drying rack, comprising several groups of scissor pairs, each scissor pair consisting of two scissor blades. Among them, one of the upper and lower adjacent scissor blades is provided with a sinking portion, which is inserted into the other scissor blade when stacked, effectively reducing the space occupied by the scissor rack after stacking. The scissor rack can be composed of three-hole or five-hole scissor pairs, and the scissor blades can be metal sheets or stainless steel sheets.

[0006] The patent, titled "Scissor Rack and Telescopic Bracket System and Clothes Dryer" (application number: 202121320751.3), discloses a scissor rack comprising a main body formed by a plurality of hinged main rods, with a first main rod and a second main rod, with overlapping areas between the main rods, and hinge holes or shafts designed to avoid the other main rods. Furthermore, a telescopic bracket system and clothes drying machine are disclosed, utilizing the aforementioned scissor rack to enhance stability through a slide rail mechanism and anti-sway assembly.

[0007] The patent, titled "Scissor Rack, Bracket, and Clothes Dryer" (application number: 202221173729.5), provides a scissor rack with a main frame hinged to at least three folding units, each of which includes a first and second cross-hinged rod. The first folding units at both ends have fewer rods, while the second folding unit in the middle can have three or more rods to improve structural strength. Corresponding bracket and clothes drying rack designs are also provided.

[0008] The above patents all reduce the height after folding through clever structural design to save space, but the reduction in folded height is relatively limited and the folding effect is not good. Utility Model Content

[0055] like Figure 2-4As shown, this embodiment provides a system for optimizing the folding height of a telescopic bracket 300 for an electric clothes drying machine. The system includes five sets of X-shaped shear pairs: a first-level X-shaped shear pair 10, a second-level X-shaped shear pair 20, a third-level X-shaped shear pair 30, a fourth-level X-shaped shear pair 40, and a fifth-level X-shaped shear pair 50. The first-level X-shaped shear pair 10 has two upper ends connected to the clothes drying main unit 100, while the fifth-level X-shaped shear pair 50 has two lower ends connected to the drying unit 200.

[0056] like Figure 5-7 As shown, the first-level X-shaped scissors pair 10, the third-level X-shaped scissors pair 30 and the fifth-level X-shaped scissors pair 50 are single-layer X-shaped scissors racks S; the second-level X-shaped scissors pair 20 and the fourth-level X-shaped scissors pair 40 are double-layer X-shaped scissors racks P.

[0057] The single-layer X-shaped scissor stand S consists of two first single rods a, positioned close together and pivotally connected. The double-layer X-shaped scissor stand P consists of two X-shaped single-layer assemblies B, spaced apart and parallel in the thickness direction. Each X-shaped single-layer assembly B includes two second single rods b, positioned close together and pivotally connected. The ends of the two second single rods b, spaced apart in the two X-shaped single-layer assemblies B in each level of the double-layer X-shaped scissor stand P, are pivotally connected by a connecting axis z.

[0058] The cross structure of the X-shaped single-layer components B of each level of the double-layer X-shaped scissor rack P is consistent. That is, the inner and outer cross patterns are consistent.

[0059] The ends of the first single rods a of adjacent single-layer X-shaped scissors racks S are axially connected to the middle of the corresponding adjacent connecting axes z; and the connection positions of the two first single rods a of the same single-layer X-shaped scissors rack S and the connecting axis z are staggered in the thickness direction.

[0060] like Figure 8-10 As shown, the double-layer X-shaped scissors rack P forms two upper and lower folding hidden areas. When folded, the two first single rods a of the two single-layer X-shaped scissors racks S located on the upper and lower sides of the double-layer X-shaped scissors rack P enter the folding hidden area of ​​the double-layer X-shaped scissors rack P. The folded upper end of the lower double-layer X-shaped scissors rack P partially enters the folded lower end of the upper double-layer X-shaped scissors rack P.

[0061] By introducing an alternating combination of single-layer and double-layer X-shaped scissor racks, the height of the telescopic bracket in its folded state is optimized. Compared to traditional designs, the folded telescopic bracket is smaller, more suitable for the compact, lightweight, and concealed modern design of the clothes drying rack, and is particularly suitable for living environments with limited space. The staggered connection between the two first single rods a and the connecting axis z of the same single-layer X-shaped scissor rack S in the thickness direction effectively avoids interference during the folding process, further improving folding efficiency and compactness. The layered and parallel design not only optimizes the folding space but also significantly improves the overall stability and load-bearing capacity of the clothes drying rack by increasing the number of structural layers and intersections.

[0062] As Figure 1 shown, by this structural design, the height of the telescopic bracket 300 is reduced, thus more favorably realizing the hidden design of the telescopic bracket, so that the drying unit 200 in the folded state is close to the clothes drying main machine 100, and the telescopic bracket is hidden in the storage space between the two.

[0063] Based on the technical concept of the embodiment, the number of X-shaped scissors pairs can be set to an odd number greater than 3. That is, the scheme can be expanded to the following structure.

[0064] The embodiment provides a telescopic bracket folding height optimization system of an electric clothes drying machine, which comprises N groups of X-shaped scissors pairs arranged alternately in the height direction; N is an odd number greater than 3.

[0065] The N groups of X-shaped scissors pairs comprise single-layer X-shaped scissors frames S and double-layer X-shaped scissors frames P alternately, and the first stage and the last stage are both single-layer X-shaped scissors frames S. The single-layer X-shaped scissors frame S comprises two first single rods a in close contact and in shaft connection, and the double-layer X-shaped scissors frame P comprises two X-shaped single-layer assemblies B in parallel and in certain spacing in the thickness direction, each X-shaped single-layer assembly B comprising two second single rods b in close contact and in shaft connection.

[0066] The end portions of the two second single rods b of each double-layer X-shaped scissors frame P in parallel and in spacing are in shaft connection through a connecting shaft z; the end portions of the first single rods a of the adjacent single-layer X-shaped scissors frames S are in shaft connection in the middle of the corresponding adjacent connecting shaft z; the connecting positions of the two first single rods a of the same single-layer X-shaped scissors frame S and the connecting shaft z are staggered in the thickness direction; the double-layer X-shaped scissors frame P forms two folding hidden areas above and below, and when folding, the two first single rods a of the two single-layer X-shaped scissors frames S located on the upper and lower sides of the double-layer X-shaped scissors frame P enter the folding hidden area of the double-layer X-shaped scissors frame P.

[0067] Of course, when N is an odd number greater than 5; the cross structures of the X-shaped single-layer assemblies B of each double-layer X-shaped scissors frame P are consistent; the upper end of the folded next double-layer X-shaped scissors frame P partially enters the lower end of the folded previous double-layer X-shaped scissors frame P.

[0068] As Figure 7 , 10 shown, a limiting structure is arranged between the first single rod a and the connecting shaft z, so that the axial position between the end portion of the first single rod a and the connecting shaft z connected thereto is fixed.

[0069] A cleverly designed limiting structure is placed between the end of the first single rod a and the connecting axis z to ensure precise axial fixation of the two. This design prevents axial slippage of the first single rod a due to uneven force or vibration during the clothes drying machine's expansion or contraction, thereby ensuring structural stability and reliability. This stable structure means the clothes drying machine is more stable during use, reducing discomfort caused by vibration or shaking. Furthermore, users experience a smoother and more reliable experience when operating the clothes drying machine to expand or fold, improving overall user satisfaction.

[0070] The limiting structure can be implemented in a variety of forms, such as a limiting bearing seat, a limiting pin, a limiting slot, a spring locking device, etc. These structures each have their advantages and disadvantages, but all can effectively limit the axial movement of the first single rod a. The specific choice depends on factors such as design requirements, cost considerations, and processing difficulty.

[0071] like Figure 4 As shown, the first-level X-shaped scissors pair 10 is provided with a first auxiliary rod group D, which includes two first auxiliary connecting rods d; the two ends of each first auxiliary connecting rod d are respectively rotatably connected to the first single rod a of the first-level X-shaped scissors pair 10 and the clothes drying main unit 100, and the connection position between the first auxiliary connecting rod d and the first single rod a is located above the middle axis connection of the two first single rods a.

[0072] like Figure 4 As shown, the five-level X-shaped scissors pair 50 is provided with a second auxiliary rod group C, and the second auxiliary rod group C includes two second auxiliary connecting rods c; the two ends of each second auxiliary connecting rod c are respectively rotatably connected to the first single rod a of the five-level X-shaped scissors pair 50 and the drying unit 200, and the connection position of the second auxiliary connecting rod c and the first single rod a is located below the middle axis joint of the two first single rods a.

[0073] This design not only enhances the stability of the scissors when extended, but also shares some of the load, allowing it to withstand greater clothing weight and wind forces, extending the life of the overall structure. It helps maintain structural balance and stability during the clothes drying machine's extension and retraction process, reducing deformation or damage caused by uneven force. This layout provides additional support underneath the drying unit, enhancing the overall rigidity and stability of the structure.

[0074] like Figure 7-9 As shown, the second-stage upper section 21 of the second-stage X-shaped scissors pair 20, located above the middle shaft joint, is longer than the second-stage lower section 22. The fourth-stage upper section 41 of the fourth-stage X-shaped scissors pair 40, located above the middle shaft joint, is shorter than the fourth-stage lower section 42.

[0075] The first avoiding notch group m is arranged on the lower side of the corresponding position of the secondary upper section 21 of the secondary X-shaped scissor pair 20 and the lower section 12 of the primary X-shaped scissor pair 10, and is used for avoiding the connecting shaft z between the two lower ends of the secondary X-shaped scissor pair 20. The second avoiding notch group n is arranged on the upper side of the corresponding position of the quaternary lower section 42 of the quaternary X-shaped scissor pair 40 and the quinary upper section 51 of the quinary X-shaped scissor pair 50, and is used for avoiding the connecting shaft z between the two upper ends of the quaternary X-shaped scissor pair 40. The first avoiding notch group and the second avoiding notch group are each composed of notches arranged on the same position of a first single rod a and two second single rods b connected to the same connecting shaft z. In addition, the avoiding notch group can also be arranged at the opposite position of the first avoiding notch group and the second avoiding notch group to play the role of avoiding interference.

[0076] The asymmetric design not only optimizes the mechanical properties of the scissor pair, but also enables the upper section to more effectively guide the folding of the lower section during folding, reducing the requirement for folding space and improving folding efficiency. These notches form an avoiding space for avoiding the end and the connecting shaft z during folding, preventing interference and collision between structures, and further reducing the folding height between the scissor pairs of different levels.

[0077] The folding height optimization system of the telescopic bracket of the electric clothes drying machine is introduced, and the principle and implementation mode of the present application are described by applying specific examples. The above examples are only used to help understand the present application and the core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the present application.
