Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window transmission system and a door and window. Background Technology

[0002] In the prior art, the outer wall of the window sash is slidably connected with hardware transmission components such as a transmission shell, a locking rod, and a tilting locking pin. An aluminum rod is connected between each pair of adjacent hardware transmission components, thereby realizing the transmission connection between the hardware transmission components.

[0003] In the above structure, an aluminum rod is required to connect every two adjacent hardware transmission components.

The required length of the aluminum rod varies at different locations on the window sash, and the length of the aluminum rod at the same location also varies for different window sash models. Therefore, a significant amount of manpower and time is required to calculate and cut the aluminum rod during assembly.

[0027] To achieve this objective, the present invention adopts the following technical solution:

[0028] The door and window include a sash and the aforementioned door and window transmission system. A flexible transmission mechanism is arranged around the outer periphery of the sash and is capable of moving along the circumference of the sash. The transmission component is slidably connected to the outer wall of the sash.

[0029] The beneficial effects of this utility model are:

[0030] The door and window transmission system provided by this utility model only requires a rough estimate and cutting of the flexible transmission mechanism based on the circumference of the sash body. The flexible transmission mechanism is then loosely wound around the outer circumference of the sash body. Both the first and second end sections are connected to a tensioner. Under the action of the tensioner, at least one of the first and second end sections moves in the direction of the other, tightening the flexible transmission mechanism and bringing it to a taut state. Then, the transmission components on the outer wall of the sash body are connected to the flexible transmission mechanism. This door and window transmission system uses a tensioner to tighten the flexible transmission mechanism, thus eliminating the need for precise calculation of the flexible transmission mechanism's length or precise cutting during assembly. This reduces the difficulty of assembling the door and window transmission system with the sash body and improves assembly efficiency. Furthermore, this door and window transmission system uses a single flexible transmission mechanism wound around the outer circumference of the sash body to achieve the transmission connection between each transmission component, eliminating the need for connecting an aluminum rod between every two adjacent transmission components. This reduces the number of times the flexible transmission mechanism's length is calculated and the number of cuts required, thus improving assembly efficiency. When dealing with different types of sashes, only flexible transmission mechanisms of the same length need to be prepared for the same type of sash. It can be seen that when this door and window transmission system is applied to different types of sashes, the assembly efficiency of the sash and the door and window transmission system can be further improved.

[0060] Example 1

[0061] This embodiment provides a door and window transmission system, which is easy to assemble with the door and window sash and has high assembly efficiency.

[0062] Specifically, such as Figure 1 and Figure 2 As shown, the door and window transmission system includes a flexible transmission mechanism 100, a tensioner 200, and a transmission component 300. The flexible transmission mechanism 100 is configured to surround the outer periphery of the sash 10 of the door and window. The flexible transmission mechanism 100 can move circumferentially along the sash 10. The flexible transmission mechanism 100 includes a first end section 110 and a second end section 120. Both the first end section 110 and the second end section 120 are connected to the tensioner 200. The tensioner 200 is used to move at least one of the first end section 110 and the second end section 120 in a direction toward the other, so that the flexible transmission mechanism 100 is in a taut state. The transmission component 300 is configured to be slidably connected to the outer wall of the sash 10. The transmission component 300 is connected to the flexible transmission mechanism 100. There can be multiple transmission components 300, for example, two, four, five, or other numbers. All transmission components 300 are connected in series through the flexible transmission mechanism 100 to achieve transmission connection.

[0063] The flexible transmission mechanism 100 can be a component with certain flexible properties, such as steel rope, steel belt, copper wire, aluminum rope or aluminum belt.

[0064] When assembling the door and window transmission system with the sash body 10, it is only necessary to roughly estimate and cut the flexible transmission mechanism 100 according to the circumference of the sash body 10. The flexible transmission mechanism 100 is loosely wrapped around the outer circumference of the sash body 10. Then, both the first end section 110 and the second end section 120 are connected to the tensioner 200. Under the action of the tensioner 200, at least one of the first end section 110 and the second end section 120 moves in the direction of the other to tighten the flexible transmission mechanism 100, so that the flexible transmission mechanism 100 is in a taut state. Then, the transmission component 300 on the outer wall of the sash body 10 is connected to the flexible transmission mechanism 100. This door and window transmission system uses the tensioner 200 to tighten the flexible transmission mechanism 100. Therefore, during assembly, it is not necessary to accurately calculate the length of the flexible transmission mechanism 100 or to accurately cut the flexible transmission mechanism 100, which reduces the assembly difficulty of the door and window transmission system with the sash body 10 and improves the assembly efficiency.

[0065] On the other hand, this door and window transmission system can achieve the transmission connection between each transmission component 300 by using a complete set of flexible transmission mechanism 100 wrapped around the outer periphery of the sash body 10, eliminating the need for an aluminum rod to connect every two adjacent transmission components 300. This reduces the number of length calculations and cutting operations required for the flexible transmission mechanism 100, thus improving assembly efficiency. When dealing with different models of sash bodies 10, only the same length of flexible transmission mechanism 100 needs to be prepared for the same model of sash body 10. Therefore, applying this door and window transmission system to different models of sash bodies 10 can further improve the assembly efficiency of the sash body 10 and the door and window transmission system.

[0066] On the other hand, compared with aluminum rods, flexible transmission mechanism 100 has a certain degree of flexibility. Therefore, when each moving part slides along the outer wall of fan body 10, the noise between flexible transmission mechanism 100 and fan body 10 is lower, which is conducive to improving user experience.

[0067] Optionally, such as Figures 1 to 3As shown, the tensioner 200 includes a first connecting component 210, a second connecting component 220, an adjusting member 230, and a first positioning structure. Both the first connecting component 210 and the second connecting component 220 are slidably connected to the outer wall of the fan body 10. The second connecting component 220 is connected to the second end segment 120 and the adjusting member 230 respectively. The first connecting component 210 is connected to the first end segment 110. The end of the first connecting component 210 and the adjusting member 230 opposite to the second connecting component 220 is movably connected along the first adjustment direction D1. The first adjustment direction D1 is configured such that the first end segment 110 points to the second end segment 120 in the circumferential direction of the fan body 10. The first positioning structure is used to lock the relative position of the first connecting component 210 and the adjusting member 230. When it is necessary to tighten the flexible transmission mechanism 100, the relative positions of the first connecting component 210 and the adjusting component 230 are adjusted so that the first connecting component 210 drives the first end segment 110 to move toward the second end segment 120 to tighten the flexible transmission mechanism 100. Then, the relative positions of the first connecting component 210 and the adjusting component 230 are locked by the first positioning structure so that the flexible transmission mechanism 100 remains taut.

[0068] Furthermore, the adjusting member 230 has a rod-shaped structure, and the first connecting component 210 and the second connecting component 220 are configured to be located on the same side of the sash body 10, that is, the first end section 110 and the second end section 120 are located on the same side of the sash body 10. At this time, the direction from the first end section 110 to the second end section 120 is the first adjusting direction D1. This structure can reduce the operational difficulty when adjusting the relative position of the first connecting component 210 and the adjusting member 230, and is conducive to further improving the assembly efficiency of the sash body 10 and the door and window transmission system.

[0069] In another embodiment, the adjusting member 230 includes a connecting rope, a first connecting part, and a second connecting part. The two ends of the connecting rope are connected to the first connecting part and the second connecting part, respectively. The first connecting part is movably connected to the first connecting assembly 210 along a first adjusting direction D1. A first positioning structure is used to lock the relative position of the first connecting part and the first connecting assembly 210. The second connecting part is connected to the second connecting assembly 220. Because the connecting rope is flexible and bendable, the first connecting assembly 210 and the second connecting assembly 220 can be located on the same side of the fan body 10, or on two adjacent sidewalls of the fan body 10, or on the arc-shaped sidewall of the fan body 10 (e.g., the arc-shaped area of ​​a circular, fan-shaped, or elliptical fan body 10).

[0070] Furthermore, the tensioner 200 also includes a second positioning structure. The second connecting component 220 and the adjusting component 230 are movably connected along a second adjustment direction D2, where the second end segment 120 points towards the first end segment 110. The second positioning structure is used to lock the relative position of the second connecting component 220 and the adjusting component 230. This structure improves the operational flexibility when tensioning the flexible transmission mechanism 100. Specifically, when tensioning the flexible transmission mechanism 100 by the tensioner 200, it can be achieved in two ways. Method 1: Adjust the relative position of the first connecting component 210 and the adjusting component 230 along the first adjustment direction D1, so that the first connecting component 210 drives the first end segment 110 to move towards the second end segment 120 to tension the flexible transmission mechanism 100. Then, the first positioning structure locks the relative position of the first connecting component 210 and the adjusting component 230 to keep the flexible transmission mechanism 100 taut. Method 2: Adjust the relative positions of the second connecting component 220 and the adjusting member 230 along the second adjustment direction D2, so that the second connecting component 220 drives the second end segment 120 to move towards the first end segment 110, thereby tightening the flexible transmission mechanism 100. Then, the relative positions of the second connecting component 220 and the adjusting member 230 are locked by the second positioning structure, keeping the flexible transmission mechanism 100 taut. It can be seen that this structure achieves the effect of double-end adjustment of the tensioner 200, allowing for selection of operation based on installation conditions, which helps to further reduce the assembly difficulty of the door and window transmission system and the sash body 10.

[0071] In this embodiment, the first end segment 110 and the second end segment 120 are located on the same side of the fan body 10, so the first adjustment direction D1 is opposite to the second adjustment direction D2.

[0072] Furthermore, the first positioning structure includes a threaded first threaded hole 241 and a first external thread, and the second positioning structure includes a threaded second threaded hole and a second external thread. The first threaded hole 241 is located on the first connecting assembly 210, and the second threaded hole is located on the second connecting assembly 220. The axis of the first threaded hole 241 is parallel to the first adjustment direction D1, and the axis of the second threaded hole is parallel to the second adjustment direction D2. The first external thread and the second external thread are located at opposite ends of the adjusting member 230, and their rotation directions are opposite. When the flexible transmission mechanism 100 is tightened, turning the adjusting member 230 causes the first connecting assembly 210 and the second connecting assembly 220 to move simultaneously in a direction of mutual approach, thereby causing the first end section 110 and the second end section 120 to move simultaneously in a direction of mutual approach, enabling the flexible transmission mechanism 100 to be tightened quickly and improving the efficiency of tightening the flexible transmission mechanism 100. After the flexible transmission mechanism 100 is tightened, stopping the turning of the adjusting component 230 locks the relative positions of the adjusting component 230, the first connecting component 210, and the second connecting component 220. This structure achieves a "tightening upon turning, positioning upon stopping turning" operation mode, reducing the operational difficulty of the tensioner 200 and further improving the tightening efficiency of the flexible transmission mechanism 100. Furthermore, this structure achieves continuous tightening of the flexible transmission mechanism 100, ensuring that the tension on the flexible transmission mechanism 100 is moderate when it is taut. This helps maintain the tightness and shape of the flexible transmission mechanism 100, avoiding the problem of slight loosening due to low tension and the problem of breakage due to high tension.

[0073] Optionally, the adjusting component 230 can be a standard part such as a double-ended screw to facilitate procurement and production.

[0074] In another embodiment, the first connecting component 210 is provided with a first movable hole, the axis of which is parallel to the first adjustment direction D1. The end of the adjusting component 230 facing away from the second connecting component 220 is movably inserted into the first movable hole along the first adjustment direction D1. The first positioning structure includes a first limiting groove, a first limiting hole, and a first pin. The first limiting groove is formed on the side wall of the adjusting component 230. There are multiple first limiting holes, which are spaced apart along the first adjustment direction D1 on the hole wall of the first movable hole. The first pin is detachably inserted into the first limiting hole and the first limiting groove.

[0075] In another embodiment, the second connecting component 220 is provided with a second movable hole, the axis of which is parallel to the second adjustment direction D2. The end of the adjusting component 230 facing away from the first connecting component 210 is movably inserted into the second movable hole along the second adjustment direction D2. The second positioning structure includes a second limiting groove, a second limiting hole, and a second pin. The second limiting groove is formed on the side wall of the adjusting component 230. There are multiple second limiting holes, which are spaced apart along the second adjustment direction D2 on the hole wall of the second movable hole. The second pin is detachably inserted into the second limiting hole and the second limiting groove.

[0076] Optionally, the first connecting assembly 210 includes a first connecting block 211, a first clamping member, and a first bolt 213. A first threaded hole 241 is formed on the first connecting block 211. The first clamping member includes a first base 2121 and a first nut 2122. The first nut 2122 is connected to the first base 2121. A first connecting hole 2122a is formed on the side wall of the first nut 2122. The first nut 2122 passes through the first connecting block 211. The first bolt 213 is threadedly engaged with the first nut 2122. The first end segment 110 is located in the first connecting hole 2122a and is clamped between the first bolt 213 and the hole wall of the first connecting hole 2122a, thereby realizing the connection between the first end segment 110 and the first connecting assembly 210. The nut of the first bolt 213 and the first base 2121 abut against the two sides of the first connecting block 211, thereby realizing the connection between the first connecting block 211, the first clamping member, and the first bolt 213.

[0077] This structure connects the first connecting component 210 and the first end segment 110 by clamping, which avoids the problem of gaps between the first connecting component 210 and the first end segment 110 caused by dimensional deviations. This improves the transmission accuracy between the first connecting component 210 and the first end segment 110, and thus improves the transmission accuracy between the first connecting component 210 and the flexible transmission mechanism 100. Since the flexible transmission mechanism 100 is wrapped around the outer periphery of the fan body 10 as a whole, and all transmission components 300 are connected to the flexible transmission mechanism 100, this structure is beneficial to improving the transmission accuracy between the various transmission components 300.

[0078] Of course, in other embodiments, the connection between the first connecting component 210 and the first end segment 110 can also be achieved by other structures, such as using glue to bond and fix the first end segment 110 to the first connecting component 210.

[0079] The second connecting assembly 220 includes a second connecting block 221, a second clamping member, and a second bolt 223. A second threaded hole is formed on the second connecting block 221. The second clamping member includes a second base 2221 and a second nut 2222. The second nut 2222 is connected to the second base 2221. A second connecting hole 2222a is formed on the side wall of the second nut 2222. The second nut 2222 passes through the second connecting block 221. The second bolt 223 is threadedly engaged with the second nut 2222. The second end segment 120 is located in the second connecting hole 2222a and is clamped between the second bolt 223 and the hole wall of the second connecting hole 2222a, thereby realizing the connection between the second end segment 120 and the second connecting assembly 220. The nut of the second bolt 223 and the second base 2221 respectively abut against the two sides of the second connecting block 221, thereby realizing the connection between the second connecting block 221, the second clamping member, and the second bolt 223. This structure connects the second connecting component 220 and the second end segment 120 by clamping, which avoids the problem of gaps between the second connecting component 220 and the second end segment 120 caused by dimensional deviations. This improves the transmission accuracy between the second connecting component 220 and the second end segment 120, and thus improves the transmission accuracy between the second connecting component 220 and the flexible transmission mechanism 100, which is beneficial to improving the transmission accuracy between each transmission component 300.

[0080] Of course, in other embodiments, the connection between the second connecting component 220 and the second end segment 120 can also be achieved by other structures, such as using glue to bond and fix the second end segment 120 to the second connecting component 220.

[0081] Optionally, such as Figures 1 to 5 As shown, the door and window transmission system also includes a guide 400. The sash 10 includes a horizontal frame 11 and a vertical frame 12. The horizontal frame 11 and the vertical frame 12 are connected, and an outer corner portion 13 and an inner corner portion are formed in the connected area. The guide 400 includes a support base 410 and a guide structure. The support base 410 is configured to be connected to the outer corner portion 13. The guide structure is movably connected to the flexible transmission mechanism 100. The guide structure enables the flexible transmission mechanism 100 located at the horizontal frame 11 to move in the direction of extension of the horizontal frame 11. The guide structure enables the flexible transmission mechanism 100 located at the vertical frame 12 to move in the direction of extension of the vertical frame 12. This enables the guide 400 to guide the flexible transmission mechanism 100, preventing the flexible transmission mechanism 100 from moving along the extension direction of the edge 14 of the outer corner portion 13. This not only makes the movement of the flexible transmission mechanism 100 along the circumference of the fan body 10 smoother and reduces the probability of the flexible transmission mechanism 100 getting stuck, but also improves the transmission accuracy between the various transmission components 300.

[0082] Furthermore, since the flexible transmission mechanism 100 is integrally wound around the outer periphery of the fan body 10 and is in a taut state, the flexible transmission mechanism 100, which is movably connected to the guide structure, can press the support base 410 onto the outer corner portion 13, thus connecting the guide 400 to the outer corner portion 13. When assembling the guide 400 and the fan body 10, no additional connecting elements or structures are required. Only the tensioner 200 needs to be adjusted; the flexible transmission mechanism 100 is tightened under the tension of the tensioner 200, thereby completing the assembly of the guide 400 and the fan body 10. This structural design is simple, reducing not only the number of parts required for assembling the guide 400 and the fan body 10 but also the number of operational steps involved in assembling them, which helps to reduce production costs and improve assembly efficiency.

[0083] In this embodiment, there are two horizontal frame 11 and two vertical frame 12. The horizontal frame 11 and the vertical frame 12 are alternately distributed and connected end to end in sequence to form a square fan body 10 with four outer corners 13 and four inner corners. Each outer corner 13 is provided with a guide 400 to improve the guiding effect on the flexible transmission mechanism 100.

[0084] Furthermore, the guide 400 also includes a pulley 430, which is rotatably connected to the support base 410. The axis of the pulley 430 is configured to be parallel to the edge 14 of the outer corner portion 13. The horizontal frame 11 and the vertical frame 12 are located on both sides of the pulley 430. The guide structure includes a fourth guide portion 424, which is disposed on the outer periphery of the pulley 430 and distributed along the circumference of the pulley 430. The flexible transmission mechanism 100 spans the pulley 430 and is movably connected to the fourth guide portion 424. The fourth guide portion 424 guides the flexible transmission mechanism 100. When the flexible transmission mechanism 100 moves along the circumference of the fan body 10, the pulley 430 rotates, reducing the friction between the flexible transmission mechanism 100 and the pulley 430 and lowering the probability of wear problems in the flexible transmission mechanism 100.

[0085] Furthermore, the fourth guide portion 424 is located at the middle position of the pulley 430 in the axial direction, so that the pressing force applied by the flexible transmission mechanism 100 to the pulley 430 is more uniform, thereby improving the stability of the guide 400 installed in the outer corner portion 13.

[0086] Optionally, the fourth guide section 424 includes a first guide groove 4241, which is formed on the outer periphery of the pulley 430. The first guide groove 4241 extends along the circumference of the pulley 430 and is connected end to end. The flexible transmission mechanism 100 slides in cooperation with the first guide groove 4241, and the first guide groove 4241 provides a guiding function for the flexible transmission mechanism 100.

[0087] In another embodiment, the fourth guide portion 424 includes a protruding component that protrudes from the outer periphery of the pulley 430. The protruding component can be a convex ridge that extends circumferentially along the pulley 430 and is connected end to end, or it can be a plurality of protrusions that are evenly distributed circumferentially along the pulley 430. There are two sets of protruding components, which are spaced apart along the axial direction of the pulley 430. The flexible transmission mechanism 100 is slidably disposed between the two sets of protruding components, and the two sets of protruding components provide a guiding function for the flexible transmission mechanism 100.

[0088] Optionally, the support base 410 includes a first frame plate 414, a second frame plate 415, and a rotating shaft 416. The rotating shaft 416 and the pulley are both located between the first frame plate 414 and the second frame plate 415. The two ends of the rotating shaft 416 are respectively connected to the first frame plate 414 and the second frame plate 415, and the pulley 430 is rotatably connected to the rotating shaft 416. While the flexible transmission mechanism 100 slides in cooperation with the fourth guide portion 424 on the pulley 430, the taut flexible transmission mechanism 100 applies a pressing force to the pulley 430. The direction of this pressing force is from the outer corner portion 13 to the inner corner portion. The pulley 430 transmits this pressing force to the first frame plate 414 and the second frame plate 415 through the rotating shaft 416, so that the first frame plate 414 and the second frame plate 415 are pressed against the outer corner portion 13. Of course, in other embodiments, the support base 410 can also be a support block or other structures. The taut flexible transmission mechanism 100 can also transmit the pressing force to the support base 410 through the pulley 430, so that the support base 410 is pressed against the outer corner portion 13.

[0089] In this embodiment, the flexible transmission mechanism 100 includes a first flexible element 151, which is a component with certain flexibility, such as a steel rope, steel strip, copper wire, aluminum rope, or aluminum strip. The two ends of the first flexible element 151 are a first end segment 110 and a second end segment 120, respectively. When assembling the door and window transmission system and the sash body 10, it is only necessary to roughly estimate the length of the first flexible element 151 based on the circumference of the sash body 10 and cut out one first flexible element 151.

[0090] It should be noted that the number of first flexible members 151 can be one, two or more. When the transmission resistance is large, each transmission member 300 is connected to all first flexible members 151. In this way, the structure of using multiple first flexible members 151 for transmission can reduce the probability of a single first flexible member 151 breaking.

[0091] This embodiment also provides a door and window, which includes a sash 10 and the aforementioned door and window transmission system. A flexible transmission mechanism 100 is arranged around the outer periphery of the sash 10 and can move circumferentially along the sash 10. A transmission member 300 is slidably connected to the outer wall of the sash 10. This door and window uses the aforementioned door and window transmission system, eliminating the need for precise calculation of the length of the flexible transmission mechanism 100 or precise cutting of the flexible transmission mechanism 100. The flexible transmission mechanism 100 can be roughly estimated and cut based on the perimeter of the sash 10, and then tightened under the action of the tensioner 200 to achieve the assembly of the door and window transmission system with the sash 10. This reduces the assembly difficulty of the door and window transmission system with the sash 10 and improves assembly efficiency. In addition, when assembling the door and window transmission system and the sash 10, the number of times the flexible transmission mechanism 100 calculates the length and the number of cuts are significantly reduced. In particular, when the door and window transmission system needs to be assembled onto different models of sash 10, only the same length of flexible transmission mechanism 100 needs to be prepared for the same model of sash 10, which further improves the assembly efficiency of the door and window transmission system and the sash 10.

[0092] It should be noted that the term "doors and windows" refers to both doors and windows collectively; that is, it can refer to either doors or windows. Similarly, "sash 10" refers to both door sashes and window sashes collectively; it can refer to either door sashes or window sashes. The door and window transmission system provided in this embodiment can be applied to various types of doors and windows, such as side-press windows, inward-opening and tilt-and-turn windows, etc. The transmission components 300 differ for different types of doors and windows. In this embodiment, the window type is a side-press window, and the transmission component 300 includes a transmission housing, a locking rod, a side-press lower pulley 430, and a side-press upper pulley 430, etc.

[0093] Example 2

[0094] This embodiment provides a door and window transmission system. The following mainly describes the differences between this embodiment and Embodiment 1, while the similarities will not be repeated.

[0095] like Figure 6 and Figure 7As shown, the tensioner 200 also includes an elastic element 250. Along the first adjustment direction D1, the elastic element 250 is in a compressed state. The adjustment element 230 includes an adjustment body 231 and an abutment portion 232. The adjustment body 231 is a rod-shaped structure and is movably inserted into the second connecting assembly 220. One end of the adjustment body 231 is movably connected to the first connecting assembly 210 along the first adjustment direction D1. A first positioning structure is used to lock the relative position of the adjustment body 231 and the first connecting assembly 210. The other end of the adjustment body 231 is connected to the abutment portion 232, which protrudes from the side wall of the adjustment body 231. One end of the elastic element 250 in the first adjustment direction D1 abuts against the portion of the second connecting assembly 220 away from the first connecting assembly 210, and the other end abuts against the side of the abutment portion 232 facing the first connecting assembly 210. The elastic element 250 can be a spring or rubber, or other elements with a certain degree of elasticity.

[0096] When the flexible transmission mechanism 100 lengthens due to plastic deformation, the tensioner 200 can adaptively tighten to re-tighten the lengthened flexible transmission mechanism 100, thereby improving the transmission reliability and accuracy of the flexible transmission mechanism 100 and ensuring high transmission accuracy between each transmission component 300. Specifically, since the elastic element 250 is in a compressed state in the first adjustment direction D1, the elastic element 250 stores a certain amount of elastic potential energy in the first adjustment direction D1. At this time, the portion of the second connecting assembly 220 away from the first connecting assembly 210 and the abutment portion 232 apply a compressive force to the elastic element 250. When the flexible transmission mechanism 100 lengthens due to plastic deformation, it changes from a taut state to a loose state. At this time, the compressive force exerted on the elastic member 250 by the portion of the second connecting component 220 away from the first connecting component 210 and the abutment portion 232 decreases. The elastic member 250 releases its elastic potential energy and rebounds. The rebounding elastic member 250 drives the second connecting component 220 to move towards the first connecting component 210. The second end segment 120 moves synchronously with the second connecting component 220, that is, the second end segment 120 moves along the second adjustment direction D2. During this process, the second end segment 120 gradually approaches the first end segment 110, so that the flexible transmission mechanism 100 is re-tightened. It can be seen that when the flexible transmission mechanism 100 lengthens due to plastic deformation, the elastic member 250 can quickly re-tighten the lengthened flexible transmission mechanism 100, which not only eliminates the need for manual tightening but also shortens the response time for re-tightening the flexible transmission mechanism 100.

[0097] Optionally, the first positioning structure includes a first threaded hole 241 and a first external thread. The first threaded hole 241 is located on the first connecting assembly 210, and the axis of the first threaded hole 241 is parallel to the first adjustment direction D1. The first external thread is located at one end of the adjusting body 231. When assembling the door and window transmission system and the sash 10, the adjusting body 231 is screwed on to compress the elastic element 250 until the flexible transmission mechanism 100 is initially tightened. This structure is relatively simple. By screwing on the adjusting body 231, the elastic element 250 can be compressed and the flexible transmission mechanism can be initially tightened. Stopping the screwing locks the relative position of the adjusting body 231 and the first connecting assembly 210, and also achieves the effect of continuous tightening when the flexible transmission mechanism 100 is initially tightened. In this embodiment, the adjusting element 230 is a standard part such as a bolt or screw to facilitate procurement and manufacturing. The aforementioned abutment part 232 is the nut of the bolt.

[0098] Optionally, the elastic element 250 is sleeved on the adjusting body 231 so that the adjusting body 231 can radially limit the elastic element 250 and prevent the elastic element 250 from radially deforming.

[0099] Example 3

[0100] This embodiment provides a door and window transmission system and a door and window. The following mainly describes the differences between this embodiment and Embodiment 2, while the similarities will not be repeated.

[0101] In this embodiment, the window type is an inward-opening and inward-tilting window, and the transmission component 300 includes a transmission housing, a locking rod, and a tilting locking pin, etc.

[0102] like Figure 8 and Figure 9 As shown, in this embodiment, there are two first flexible members 151. Each transmission member 300 is connected to two first flexible members 151. Each first flexible member 151 is provided with a first end segment 110 and a second end segment 120. The first end segment 110 of the two first flexible members 151 is connected to the first connecting component 210, and the second end segment 120 of the two first flexible members 151 is connected to the second connecting component 220.

[0103] Optionally, such as Figures 8 to 11 As shown, the second connecting assembly 220 has a movable cavity 224. The adjusting body 231 is movably inserted through the side wall of the movable cavity 224 facing the first connecting assembly 210. The abutment portion 232 is movably disposed within the movable cavity 224. The elastic member 250 is located within the movable cavity 224, and the end of the elastic member 250 facing away from the abutment portion 232 abuts against the inner wall of the movable cavity 224 facing the first connecting assembly 210. This protects the elastic member 250 and extends its service life.

[0104] In this embodiment, the elastic member 250 is in a compressed state in the first adjustment direction D1, and one end of the elastic member 250 in the first adjustment direction D1 abuts against the inner wall of the movable cavity 224 facing the first connecting component 210, and the other end abuts against the side of the abutting part 232 facing the first connecting component 210. Therefore, the elastic member 250 stores a certain elastic potential energy in the first adjustment direction D1. At this time, the movable cavity 224 and the inner wall of the first connecting component 210 and the abutting part 232 apply a squeezing force to the elastic member 250. When the flexible transmission mechanism 100 lengthens due to plastic deformation, it changes from a taut state to a loose state. At this time, the squeezing force exerted by the movable cavity 224 on the elastic member 250 towards the inner wall of the first connecting component 210 and the abutment part 232 decreases. The elastic member 250 releases its elastic potential energy and rebounds. The rebounding elastic member 250 drives the second connecting component 220 to move towards the first connecting component 210. The second end segment 120 moves synchronously with the second connecting component 220, that is, the second end segment 120 moves along the second adjustment direction D2. During this process, the second end segment 120 gradually approaches the first end segment 110 so that the flexible transmission mechanism 100 is re-tightened, thereby achieving the adaptive tensioning effect of the tensioner 200.

[0105] Furthermore, the tensioner 200 also includes a third positioning structure. The other end of the adjusting body 231 is movably connected to the abutment 232 in a direction parallel to the first adjusting direction D1. The third positioning structure is used to lock the relative position of the other end of the adjusting body 231 and the abutment 232. When the flexible transmission mechanism 100 is initially tightened, this structure improves the flexibility of operation when manually tightening the flexible transmission mechanism 100. Specifically, when the flexible transmission mechanism 100 is tightened by the tensioner 200, it can be achieved in two ways. Method 1: Adjust the relative position of the first connecting component 210 and the adjusting body 231 along the first adjusting direction D1, so that the first connecting component 210 drives the first end segment 110 to move toward the second end segment 120 to tighten the flexible transmission mechanism 100. Then, the first positioning structure locks the relative position of the first connecting component 210 and the adjusting body 231 to keep the flexible transmission mechanism 100 taut. Method 2: Adjust the relative position of the adjusting body 231 and the abutment 232 along a direction parallel to the first adjustment direction D1, so that the adjusting body 231 moves relative to the abutment 232 along the first adjustment direction D1. At this time, since the end of the adjusting body 231 away from the second connecting component 220 is connected to the first connecting component 210, the first connecting component 210 moves synchronously with the adjusting body 231, and the first end segment 110 moves synchronously with the first connecting component 210 along the first adjustment direction D1 to tighten the flexible transmission mechanism 100. Then, the relative position of the adjusting body 231 and the abutment 232 is locked by the third positioning structure, so that the flexible transmission mechanism 100 remains taut. It can be seen that this structure achieves the effect of double-end adjustment of the tensioner 200, and the operation can be selected according to the installation conditions, which is conducive to further reducing the assembly difficulty of the door and window transmission system and the sash 10.

[0106] Furthermore, the first positioning structure includes a threaded first threaded hole 241 and a first external thread, and the third positioning structure includes a threaded third threaded hole and a third external thread. The first threaded hole 241 is located on the first connecting assembly 210, and the third threaded hole is located on the abutment portion 232. The axes of the first threaded hole 241 and the third threaded hole are both parallel to the first adjustment direction D1. The first external thread and the third external thread are located at opposite ends of the adjusting body 231, and their rotation directions are opposite. When the flexible transmission mechanism 100 is tightened, turning the adjusting body 231 causes the first connecting assembly 210 and the second connecting assembly 220 to move simultaneously in a direction of mutual approach, thereby causing the first end section 110 and the second end section 120 to move simultaneously in a direction of mutual approach, enabling the flexible transmission mechanism 100 to be tightened quickly and improving the efficiency of tightening the flexible transmission mechanism 100. After the flexible transmission mechanism 100 is tightened, stopping the turning of the adjusting body 231 locks the relative positions of the adjusting body 231, the first connecting component 210, and the abutment part 232. This achieves the operation mode of "tightening upon turning and positioning upon stopping turning," reducing the operational difficulty of the tensioner 200 and further improving the tightening efficiency of the flexible transmission mechanism 100. Furthermore, this structure achieves continuous tightening of the flexible transmission mechanism 100, resulting in moderate tension on the flexible transmission mechanism 100 when it is taut, which helps maintain the tightness and shape of the flexible transmission mechanism 100.

[0107] Optionally, the adjusting body 231 can be a standard part such as a double-headed screw to facilitate procurement and production.

[0108] Optionally, the abutment portion 232 includes a movable plate and an adjusting nut fixed to the movable plate, and the third threaded hole is the threaded structure on the adjusting nut. Of course, in other embodiments, the abutment portion 232 can also be a movable block with a third threaded hole, so that the third threaded hole mates with the third external thread.

[0109] In another embodiment, the first connecting component 210 is provided with a first sliding groove, which extends along a first adjustment direction D1. One end of the adjusting body 231 is provided with a first slide rail that slides in cooperation with the first sliding groove. The first positioning structure includes a first magnet and a first iron sheet. The first magnet is embedded in the side of the first slide rail facing the bottom of the first sliding groove. There are multiple first iron sheets, which are intermittently embedded in the bottom of the first sliding groove along the extension direction of the first sliding groove. The first magnet and the first iron sheet are detachably adsorbed and connected.

[0110] In another embodiment, the abutment portion 232 is a block structure, and a third movable hole is provided on the abutment portion 232. The axis of the third movable hole is parallel to the first adjustment direction D1. The end of the adjustment body 231 facing away from the first connecting assembly 210 is movably inserted into the third movable hole. The third positioning structure includes a second magnet and a second iron sheet. The second magnet is embedded in the outer wall of the adjustment body 231. There are multiple second iron sheets. The multiple second iron sheets are embedded at intervals in the hole wall of the third movable hole along the axial direction of the third movable hole. The second magnet and the second iron sheet are detachably adsorbed and connected.

[0111] Optionally, such as Figures 8 to 13 As shown, the support base 410 of the guide 400 includes a first base 411 and a second base 412 connected to each other. The first base 411 is configured to connect with the region of the outer corner portion 13 parallel to the horizontal frame 11, and the second base 412 is configured to connect with the region of the outer corner portion 13 parallel to the vertical frame 12. The guide structure includes a first guide portion 421 and a second guide portion 422. The first guide portion 421 is located on the first base 411, and the extension direction of the first guide portion 421 is the extension direction of the horizontal frame 11. The second guide portion 422 is located on the second base 412, and the extension direction of the second guide portion 422 is the extension direction of the vertical frame 12. Both the first guide portion 421 and the second guide portion 422 are movably connected to the flexible transmission mechanism 100. The first guide portion 421 and the second guide portion 422 guide the flexible transmission mechanism 100, so that the moving direction of the flexible transmission mechanism 100 located at the horizontal frame 11 is the extending direction of the horizontal frame 11, and the moving direction of the flexible transmission mechanism 100 located at the vertical frame 12 is the extending direction of the vertical frame 12.

[0112] In addition, while the flexible transmission mechanism 100 is in a taut state, it applies a pressing force to the first seat 411 and the second seat 412 in the direction of the outer corner portion 13, so that the first seat 411 and the second seat 412 are pressed by the flexible transmission mechanism 100 onto the outer corner portion 13, thereby realizing the connection between the corner device and the outer corner portion 13.

[0113] Furthermore, the first guide portion 421 includes a second guide groove 4211, which is formed on the side of the first base 411 away from the outer corner portion 13. The extension direction of the second guide groove 4211 is the extension direction of the horizontal frame 11, and the second guide groove 4211 is a through groove. The flexible transmission mechanism 100 slides with the second guide groove 4211, and the second guide groove 4211 provides a guiding function for the flexible transmission mechanism 100 located at the horizontal frame 11.

[0114] In one embodiment, the first guide portion 421 includes a first protrusion, which protrudes from the side of the first seat 411 away from the outer corner portion 13. There are two first protrusions, both of which extend along the extension direction of the horizontal frame 11 and are spaced apart along the axial direction of the pulley 430. The flexible transmission mechanism 100 is slidably disposed between the two first protrusions, and the two first protrusions provide guidance for the flexible transmission mechanism 100 located at the horizontal frame 11.

[0115] In another embodiment, the first guide portion 421 includes a first guide channel, which is opened on the first base 411 and extends along the extension direction of the horizontal frame 11. The flexible transmission mechanism 100 is movably disposed in the first guide channel, and the first guide channel provides guidance for the flexible transmission mechanism 100 located at the horizontal frame 11.

[0116] Optionally, the second guide portion 422 includes a third guide groove 4221, which is formed on the side of the second base 412 away from the outer corner portion 13. The extension direction of the third guide groove 4221 is the extension direction of the vertical frame 12, and the third guide groove 4221 is a through groove. The flexible transmission mechanism 100 slides with the third guide groove 4221, and the third guide groove 4221 provides a guiding function for the flexible transmission mechanism 100 located at the vertical frame 12.

[0117] In one embodiment, the second guide portion 422 includes a second protrusion that protrudes from the side of the second seat 412 away from the outer corner portion 13. There are two second protrusions, both of which extend along the extension direction of the vertical frame 12 and are spaced apart along the axial direction of the pulley 430. The flexible transmission mechanism 100 is slidably disposed between the two second protrusions, and the two second protrusions provide guidance for the flexible transmission mechanism 100 located at the vertical frame 12.

[0118] In another embodiment, the second guide portion 422 includes a second guide channel, which is opened on the second seat 412 and extends along the extension direction of the vertical frame 12. The flexible transmission mechanism 100 is movably disposed in the second guide channel, and the second guide channel provides guidance for the flexible transmission mechanism 100 located at the vertical frame 12.

[0119] Optionally, the support base 410 is provided with a notch 417, which is located between the first base 411 and the second base 412. The pulley 430 is located at the notch 417, so that the horizontal frame 11 and the vertical frame 12 are located on both sides of the pulley 430. The first guide portion 421 and the second guide portion 422 are both positioned opposite the fourth guide portion 424. Under the guidance of the fourth guide portion 424, the flexible transmission mechanism 100 can move relatively smoothly between the first guide portion 421 and the second guide portion 422, which helps to improve the consistency of the movement trajectory of the flexible transmission mechanism 100 on the outer periphery of the fan body 10, thereby improving the transmission accuracy of the flexible transmission mechanism 100. Furthermore, when the flexible transmission mechanism 100 moves, the pulley 430 rotates, reducing the friction between the flexible transmission mechanism 100 and the pulley 430, and reducing the probability of wear problems in the flexible transmission mechanism 100.

[0120] Furthermore, both the first support plate 414 and the second support plate 415 are L-shaped. The first base 411 is connected to one end of the first support plate 414 and one end of the second support plate 415 on both sides of the pulley 430 axis direction. The second base 412 is connected to the other end of the first support plate 414 and the other end of the second support plate 415 on both sides of the pulley 430 axis direction. The notch 417 is located between the first support plate and the second support plate 415, and is located at the corner of the first support plate 414 and the corner of the second support plate 415. One end of the pivot 416 is connected to the corner of the first support plate 414, and the other end is connected to the corner of the second support plate 415. While the flexible transmission mechanism 100 slides in cooperation with the fourth guide portion 424 on the pulley 430, the taut flexible transmission mechanism 100 applies a pressing force to the pulley 430. The direction of this pressing force is from the outer corner portion 13 to the inner corner portion. The pulley 430 transmits this pressing force to the first frame plate 414 and the second frame plate 415 through the rotating shaft 416. The first frame plate 414 and the second frame plate 415 transmit this pressing force to the first seat 411 and the second seat 412, so that the first seat 411 and the second seat 412 are pressed against the outer corner portion 13. In this embodiment, the flexible transmission mechanism 100 can not only directly apply a pressing force to the first seat 411 and the second seat 412, but also indirectly apply a pressing force to the first seat 411 and the second seat 412 through the pulley 430, the rotating shaft 416, the first frame plate 414 and the second frame plate 415, thereby improving the reliability and stability of the connection between the guide 400 and the outer corner portion 13.

[0121] Furthermore, the number of the first guide part 421, the second guide part 422, the fourth guide part 424, and the first flexible member 151 are all two and correspond one-to-one. The two fourth guide parts 424 are symmetrically arranged about the middle of the rotating shaft 416. This makes the pressing force applied by the two first flexible members 151 to the pulley 430, the first seat 411, and the second seat 412 more uniform, solving the problem of the guide 400 tilting due to uneven force.

[0122] Optionally, such as Figures 8 to 15 As shown, the door and window transmission system also includes a clamping mechanism, through which the transmission component 300 is connected to the flexible transmission mechanism 100. In the prior art, the connection structure between the hardware transmission component and the aluminum rod is a shaft-hole fit structure. Specifically, the hardware transmission component has a protruding connecting post, and the aluminum rod has a through hole, into which the connecting post is inserted. In actual production, due to factors such as dimensional deviations, a gap exists between the side wall of the connecting post and the wall of the through hole. This gap reduces the transmission accuracy between the hardware transmission component and the aluminum rod, and consequently reduces the transmission accuracy between the various hardware transmission components. To solve this technical problem, this embodiment proposes a scheme where the transmission component 300 is connected to the flexible transmission mechanism 100 through a clamping mechanism, eliminating the shaft-hole fit structure, thereby improving the transmission accuracy between the transmission component 300 and the flexible transmission mechanism 100, and further improving the transmission accuracy between the various transmission components 300.

[0123] Furthermore, the clamping mechanism includes a first clamping member 510, which is connected to the transmission member 300. A portion of the flexible transmission mechanism 100 is clamped between the first clamping member 510 and the transmission member 300 to achieve the connection between the transmission member 300 and the flexible transmission mechanism 100.

[0124] Furthermore, the clamping mechanism also includes a first clamping threaded hole 511 and a first clamping bolt 530. The first clamping threaded hole 511 is formed on the first clamping member 510, and the first clamping bolt 530 passes through the transmission member 300 and is threadedly engaged with the first clamping threaded hole 511. Tightening the first clamping bolt 530 can bring the first clamping member 510 and the transmission member 300 closer together until the flexible transmission mechanism 100 is clamped between the first clamping member 510 and the transmission member 300. The operation is simple, and the clamping effect of the first clamping member 510 and the transmission member 300 on the flexible transmission mechanism 100 is reliable.

[0125] In another embodiment, the clamping mechanism further includes a first insert and a first slot, wherein the first insert protrudes from the first clamping member 510, the first slot is formed on the transmission member 300, the first insert is inserted into the first slot and is interference-fitted with the first slot, so that the first clamping member 510 is connected to the transmission member 300 and cooperates to clamp the flexible transmission mechanism 100.

[0126] Furthermore, the clamping mechanism also includes a shim 540, which is clamped between the transmission member 300 and the flexible transmission mechanism 100 to increase the friction between the transmission member 300 and the flexible transmission mechanism 100, thereby improving the reliability of the transmission member 300 and the first clamping member 510 in clamping the flexible transmission mechanism 100.

[0127] It should be noted that the clamping mechanism provided in this embodiment can be applied when the number of the first flexible member 151 is one, two or more. In other words, the clamping mechanism provided in this embodiment can be applied to the structure in other embodiments such as Embodiment 1.

[0128] Example 4

[0129] This embodiment provides a door and window transmission system. The following mainly describes the differences between this embodiment and Embodiment 3, while the similarities will not be repeated.

[0130] like Figure 16 and Figure 17 As shown, the support base 410 of the guide 400 includes a first base 411, a second base 412, and a third base 413. The structures of the first base 411 and the second base 412 are the same as in Embodiment 3, and will not be described again here. The difference between this embodiment and Embodiment 3 is that the first base 411 is connected to the second base 412 through the third base 413. The guide structure also includes a third guide portion 423, which is located on the third base 413. Both ends of the third guide portion 423 are connected to the first guide portion 421 and the second guide portion 422, respectively. The end of the third guide portion 423 connected to the first guide portion 421 has the same extension direction as the first guide portion 421, and the end of the third guide portion 423 connected to the second guide portion 422 has the same extension direction as the second guide portion 422. The third guide portion 423 is movably connected to the flexible transmission mechanism 100. The third guide section 423 can provide guidance for the flexible transmission mechanism 100, enabling the flexible transmission mechanism 100 to move more smoothly between the first guide section 421 and the second guide section 422. This helps to improve the consistency of the movement trajectory of the flexible transmission mechanism 100 on the outer periphery of the fan body 10, thereby improving the transmission accuracy of the flexible transmission mechanism 100.

[0131] On the other hand, while the taut flexible transmission mechanism 100 moves, it applies a pressing force to the third seat 413 in the direction of the outer corner 13, so that the third seat 413 is pressed by the flexible transmission mechanism 100 onto the outer corner 13. That is to say, in this embodiment, the flexible transmission mechanism 100 directly applies a pressing force to the first seat 411, the second seat 412 and the third seat 413 in the direction of the outer corner 13, thereby realizing the connection between the corner device and the outer corner 13.

[0132] Furthermore, the number of the first guide portion 421, the second guide portion 422, the third guide portion 423, and the first flexible member 151 are all two and correspond one-to-one. The two third guide portions 423 are evenly distributed along the extension direction of the edge 14 of the outer corner portion 13, so that the pressing force applied by the two first flexible members 151 to the first seat 411, the second seat 412, and the third seat 413 is more uniform, thus solving the problem of the guide 400 tilting due to uneven force.

[0133] Optionally, the third guide portion 423 includes a fourth guide groove 4231, which is formed on the side of the third base 413 away from the outer corner portion 13. The two ends of the fourth guide groove 4231 are connected to the second guide groove 4211 and the third guide groove 4221 respectively. The flexible transmission mechanism 100 is slidably engaged with the fourth guide groove 4231, and the fourth guide groove 4231 provides a guiding function for the flexible transmission mechanism 100.

[0134] In one embodiment, the third guide portion 423 includes a third protrusion that protrudes from the side of the third seat 413 away from the outer corner portion 13. There are two third protrusions, which are spaced apart along the extension direction of the edge 14 of the outer corner portion 13. The flexible transmission mechanism 100 is slidably disposed between the two third protrusions, and the two third protrusions provide guidance for the flexible transmission mechanism 100.

[0135] In another embodiment, the third guide section 423 includes a third guide channel, which is opened on the third base 413. The flexible transmission mechanism 100 is movably inserted through the third guide channel, and the third guide channel provides guidance for the flexible transmission mechanism 100.

[0136] Example 5

[0137] This embodiment provides a door and window transmission system. The following mainly describes the differences between this embodiment and Embodiment 3, while the similarities will not be repeated.

[0138] In this embodiment, the clamping mechanism includes a connecting unit and a cooperating unit. The connecting unit is connected to the transmission member 300, and the connecting unit is connected to the cooperating unit. A portion of the flexible transmission mechanism 100 is clamped between the connecting unit and the cooperating unit so that the flexible transmission mechanism 100 is connected to the transmission member 300 by clamping.

[0139] Furthermore, the connecting unit can be connected to the transmission component 300 using standard parts such as screws or bolts. The connecting unit and the mating unit can be connected by a second slot and a second insert, which are used to clamp the flexible transmission mechanism 100; or, the connecting unit and the mating unit can also be connected by standard parts such as screws or bolts, which are used to clamp the flexible transmission mechanism 100.

[0140] Example 6

[0141] This embodiment provides a door and window transmission system. The following mainly describes the differences between this embodiment and Embodiment 1, while the similarities will not be repeated.

[0142] like Figure 18 and Figure 19 As shown, in this embodiment, there are two fourth guide parts 424 and two first flexible members 151, and they correspond one-to-one. The two fourth guide parts 424 are symmetrically arranged about the middle of the rotating shaft 416 so that the pressing force applied by the two first flexible members 151 to the pulley 430 is more uniform. As a result, the pressing force transmitted by the pulley 430 to the first frame plate 414 and the second frame plate 415 through the rotating shaft 416 is more uniform, which solves the problem of the guide 400 tilting due to uneven force.

[0143] Example 7

[0144] This embodiment provides a door and window transmission system and a door and window. The following mainly describes the differences between this embodiment and Embodiment 2, while the similarities will not be repeated.

[0145] like Figure 20 and Figure 21As shown, the flexible transmission mechanism 100 includes a first flexible element 151 and a second flexible element 152. Both the first flexible element 151 and the second flexible element 152 are components with certain flexibility, such as steel rope, steel strip, copper wire, aluminum rope, or aluminum strip. The materials and shapes of the first flexible element 151 and the second flexible element 152 can be the same or different. The first flexible element 151 is wound around half of the outer circumference of the fan body 10, and the second flexible element 152 is wound around the other half of the outer circumference of the fan body 10. For example, in this embodiment, the first flexible element 151 is wound around the upper half of the outer circumference of the fan body 10, and the second flexible element 152 is wound around the lower half of the outer circumference of the fan body 10. The first flexible member 151 has a first end segment 110 and a third end segment 130 at its two ends, and the second flexible member 152 has a second end segment 120 and a fourth end segment 140 at its two ends. The first end segment 110 is connected to the first connecting assembly 210 of the tensioner 200, and the second end segment 120 is connected to the second connecting assembly 220 of the tensioner 200. The third end segment 130 and the fourth end segment 140 are both clamped onto the same transmission member 300 by a clamping mechanism, thereby making the first flexible member 151 and the second flexible member 152 form a whole that wraps around the entire outer circumference of the fan body 10. For ease of description, the transmission member 300 connected to the third end segment 130 and the fourth end segment 140 is referred to as the first transmission member 310, and the other transmission members 300 are referred to as the second transmission member 320. Several second transmission components 320 are respectively connected to the first flexible component 151 and the second flexible component 152, and the first transmission component 310 and several second transmission components 320 are connected by transmission through the first flexible component 151 and the second flexible component 152.

[0146] When the circumference of the fan body 10 is long, it is difficult to operate the first flexible member 151 to wrap around the entire fan body 10. In this case, the structure of this embodiment can reduce the difficulty of operation. That is, the first flexible member 151 is wrapped around half of the fan body 10, and the second flexible member 152 is wrapped around the other half of the fan body 10. Then, the third end segment 130 and the fourth end segment 140 are both connected to the first transmission member 310, and the first end segment 110 and the second end segment 120 are connected to the tensioner 200. Finally, the tensioner 200 is adjusted so that the first end segment 110 and the second end segment 120 are brought closer to each other until the first flexible member 151 and the second flexible member 152 are both tightened for the first time. The assembly of the flexible transmission mechanism 100 and the fan body 10 can be completed.

[0147] Optionally, the third end segment 130 and the fourth end segment 140 are configured to be located on the same side of the fan body 10. The connecting unit includes a second clamping member 521 and a third clamping member 522. Both the second clamping member 521 and the third clamping member 522 are connected to the first transmission member 310. The second clamping member 521 has a first fixing hole 5211, and the third end segment 130 is located in the first fixing hole 5211. The third clamping member 522 has a second fixing hole 5221, and the fourth end segment 140 is located in the second fixing hole 5221. The unit includes a fourth clamping member 523 and a fifth clamping member 524. The fourth clamping member 523 passes through the second clamping member 521. The third end section 130 is clamped between the fourth clamping member 523 and the wall of the first fixing hole 5211. The fifth clamping member 524 passes through the third clamping member 522. The fourth end section 140 is clamped between the fifth clamping member 524 and the wall of the second fixing hole 5221. Thus, the third end section 130 and the fourth end section 140 are connected to the first transmission member 310 by clamping.

[0148] Furthermore, the second clamping member 521 is provided with a second clamping threaded hole 5212, which communicates with the first fixing hole 5211. The fourth clamping member 523 is a second clamping bolt 5231, which is threaded into the second clamping threaded hole 5212 and engages with the wall of the first fixing hole 5211 to clamp the third end section 130. Tightening the second clamping bolt 5231 will bring it closer to the wall of the first fixing hole 5211 until the third end section 130 is clamped between the second clamping bolt 5231 and the wall of the first fixing hole 5211. The operation is simple, and the clamping effect of the second clamping bolt 5231 and the wall of the first fixing hole 5211 on the third end section 130 is reliable.

[0149] In another embodiment, a third magnet is embedded in the wall of the first fixing hole 5211 on the side away from the fourth clamping member 523, and a third iron piece is embedded in the end of the fourth clamping member 523 facing the first fixing hole 5211. Under the magnetic attraction of the third magnet and the third iron piece, the fourth clamping member 523, which passes through the second clamping member 521, cooperates with the wall of the first fixing hole 5211 to clamp the third end segment 130.

[0150] Optionally, the third clamping member 522 is provided with a third clamping threaded hole 5222, which communicates with the second fixing hole 5221. The fifth clamping member 524 is a third clamping bolt 5241, which is threaded into the third clamping threaded hole 5222 and engages with the wall of the second fixing hole 5221 to clamp the fourth end section 140. Tightening the third clamping bolt 5241 will bring it closer to the wall of the second fixing hole 5221 until the fourth end section 140 is clamped between the third clamping bolt 5241 and the wall of the second fixing hole 5221. The operation is simple, and the clamping effect of the third clamping bolt 5241 and the wall of the second fixing hole 5221 on the fourth end section 140 is reliable.

[0151] In another embodiment, a fourth magnet is embedded in the hole wall of the second fixing hole 5221 on the side opposite to the fifth clamping member 524, and a fourth iron piece is embedded in the end of the fifth clamping member 524 facing the second fixing hole 5221. Under the magnetic attraction of the fourth magnet and the fourth iron piece, the fifth clamping member 524, which passes through the third clamping member 522, cooperates with the hole wall of the second fixing hole 5221 to clamp the fourth end segment 140.

[0152] The tensioner 200 provided in this embodiment has the same structure as the tensioner 200 in Embodiment 2, but the working principle is slightly different, as detailed below:

[0153] When the flexible transmission mechanism 100 is tightened for the first time, the adjusting member 230 is turned so that the first connecting component 210 drives the first end segment 110 to move along the first adjusting direction D1, so that the elastic member 250 is compressed and stores elastic potential energy until the first flexible member 151 and the second flexible member 152 are both tightened for the first time. At this time, the abutting part 232 and the side of the second connecting component 220 away from the first connecting component 210 continuously apply a squeezing force to the elastic member 250.

[0154] When the second flexible member 152 lengthens due to plastic deformation, it changes from a taut state to a loose state. At this time, the compressive force on the elastic member 250 decreases, the elastic member 250 releases its elastic potential energy and rebounds. The rebounding elastic member 250 drives the second connecting assembly 220 to move toward the first connecting assembly 210. The second end segment 120 moves synchronously with the second connecting assembly 220, that is, the second end segment 120 moves along the second adjustment direction D2. During this process, the second end segment 120 gradually approaches the first end segment 110 so that the second flexible member 152 is tightened again.

[0155] When the first flexible member 151 lengthens due to plastic deformation, it changes from a taut state to a loose state. At this time, the first reverse tension force applied by the third end section 130 to the first transmission member 310 decreases (the first flexible member 151 is stretched between the tensioner 200 and the first transmission member 310, therefore the first transmission member 310 applies a first tension force in the first adjustment direction D1 to the third end section 130, and the third end section 130 applies a first reverse tension force in the second adjustment direction D2 to the first transmission member 310). Since the second flexible member 152 is still taut, the second reverse tension force applied by the fourth end section 140 to the first transmission member 310 does not decrease (the second flexible member 152 is stretched between the tensioner 200 and the first transmission member 310, therefore the first transmission member 310 applies a second tension force in the second adjustment direction D2 to the fourth end section 140, and the fourth end section 140 applies a second reverse tension force in the first adjustment direction D1 to the first transmission member 310). The first reverse tension force on the first transmission member 310 decreases, while the second reverse tension force remains unchanged. Therefore, the first transmission member 310 moves slightly along the first adjustment direction D1. The third end segment 130 moves synchronously with the first transmission member 310, so that the first flexible member 151 is re-tightened. After the first transmission member 310 moves slightly along the first adjustment direction D1, the second flexible member 152 changes from a taut state to a loose state, which reduces the compressive force on the elastic member 250. Therefore, the elastic member 250 releases its elastic potential energy and rebounds. The rebounding elastic member 250 drives the second connecting assembly 220 to move towards the first connecting assembly 210. The second end segment 120 moves synchronously with the second connecting assembly 220, that is, the second end segment 120 moves along the second adjustment direction D2. During this process, the second end segment 120 gradually approaches the first end segment 110, so that the second flexible member 152 is re-tightened. This achieves the effect of re-tightening the first flexible member 151 and the second flexible member 152 under the rebound action of the elastic member 250.
