Description

[0001] This application is a divisional application of the utility model patent entitled "Frame Assembly", filed on August 22, 2024, by Hefei Fulian Auto Parts Co., Ltd., with application number 202422041803.3. Technical Field

[0002] This utility model relates to the technical field of frames that can be used for sunshades or insect nets for automobile sunroofs, specifically to a frame assembly. Background Technology

[0003] Car sunroofs, installed on the roof, effectively improve air circulation inside the vehicle and meet needs such as defogging, cooling, and providing a wider view. However, in summer, when the sunroof is open, flying insects can easily enter the car, causing problems such as soiling the interior and obstructing the driver's view. Therefore, insect screens are sometimes installed on car sunroofs. Sunshades are also sometimes installed to prevent sun exposure. In existing technology, both insect screens and sunshades often have a frame assembly constructed using rails and bases. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a frame assembly that can be used for insect nets or sunshades in car sunroofs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A frame assembly includes two slide rails respectively located on both sides, with a base mounted at one end of each slide rail;

[0007] A second notch is provided on the inner side of one end of the slide rail;

[0008] A guide seat is formed on the lower part of the inner sidewall of the base;

[0009] The base is installed above one end of the slide rail and the guide seat is placed in the second notch.

[0010] One possible design is that a hook seat is formed at one end of the inner sidewall of the base, the hook seat is located above the guide seat, and a hook is formed on the side of the hook seat.

[0011] One possible design is that the end of the guide seat extends upward to form an inclined guide portion for guiding the curtain into the slide rail.

[0012] One possible design is that the slide rail has a flat base plate, and a U-shaped wall with an overall inverted U-shaped cross-section extends upward from one side of the upper surface of the base plate, and the base plate and the U-shaped wall together form a first closed cavity.

[0013] One possible design is that the top surface of the U-shaped wall is recessed downward to form a transition wall with a W-shaped cross-section. The first end face at one end of the transition wall and the second end face at the middle end extend upward to form a first inclined wall and a second inclined wall, respectively. After the top of the first inclined wall intersects with the top of the second inclined wall, a transverse wall continues to extend.

[0014] One possible design is that the bottom surface of the base has an avoidance groove, and the first inclined wall of the slide rail is placed in the avoidance groove.

[0015] One possible design is that a bent wall extends upward from the third end face of the other end of the transition wall, the bent wall being located below the transverse wall and forming a gap cavity with an opening facing the inside of the slide rail between the two walls.

[0016] One possible design is that the end of the hook seat has a second mounting leg for inserting into the slide rail.

[0017] One possible design is that the top surface on the right side of the bent wall and the U-shaped wall encloses a third mounting cavity for the curtain to enter the slide rail, and a hook extends from the inner side of the bent wall, which bends toward the third mounting cavity.

[0018] One possible design is that one end of the slide rail is connected to a connecting mold base for mounting a flexible shaft.

[0019] One possible design is that a second groove is formed on the bottom surface of one end of the slide rail, and a third mounting leg is formed on the connecting mold base, which is inserted into the second groove.

[0020] One possible design is that the outer wall of the base has a connecting part, and the connecting part, one end of the slide rail of the mounting base, and the third mounting leg are stacked and fixed together.

[0021] The advantages of this invention compared to existing technologies are as follows: By utilizing the cooperation of the second notch and the guide seat, the base does not need to be connected to the end face of the slide rail along its length, thus shortening the overall length of the slide rail and reducing the space occupied by the sunshade or insect net inside the vehicle. This provides an alternative frame assembly solution for the slide rail and base assembly relationship. Simultaneously, the guide seat on the base facilitates guiding the curtain fabric into the slide rail. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] A type of insect-proof net, such as Figure 1 As shown, it can be installed on a car at the location corresponding to the sunroof, and can prevent flying insects from entering the car through the sunroof when it is open.

[0042] The aforementioned insect-proof net includes components such as two slide rails 1, a first panel 2, a second panel 3, a base 4, a roller 5, a curtain 6, and a pull rod 7.

[0043] like Figure 1 , Figure 2 Two slide rails 1 are respectively placed on both sides. The first panel 2 is installed on one end of the two slide rails 1. A base 4 is installed on the other end of each slide rail 1. A roller 5 is rotatably installed between the two bases 4. The roller 5 is the prior art with automatic winding function. A pull rod 7 that can move along the length of the slide rail is installed between the two slide rails 1. The curtain 6 is the prior art rollable insect-proof mesh fabric that can play an insect-proof role. One end of the curtain 6 is rollable and connected to the roller 5, and the other end is connected to the pull rod 7.

[0044] When the curtain 6 needs to be closed, the lever 7 is driven to move on the slide rail 1, and the roller 5 rotates to roll up the curtain 6; when the curtain 6 needs to be opened, the lever 7 is driven to move on the slide rail 1, and the roller 5 rotates to unfold the curtain 6, which can be used to prevent flying insects from entering the car through the sunroof.

[0045] The assembly relationship between the slide rail 1 and the first panel 2 and the second panel 3 is as follows: Figures 1 to 4 :

[0046] Two slide rails 1 each have a base plate 11. One end of each slide rail 1 is located on a first panel 2, and a second panel 3 is mounted on the other end of each slide rail 1, with that other end located on the second panel 3. Thus, the bottom surface of the base plate 11 of the two slide rails 1, together with the bottom surfaces of the first panel 2 and the second panel 3, constitutes a decorative surface. In other words, the bottom surface of the base plate 11 of each slide rail 1 serves as part of the overall decorative surface. The decorative surface refers to the surface that is directly exposed after the insect screen is installed on the vehicle, allowing occupants to directly observe it. This decorative surface faces inwards and serves a decorative purpose.

[0047] Traditional insect nets do not have a base plate on their guide rails, while the slide rail 1 in this solution has a base plate 11. The first panel 2 and the second panel 3 have a wider bottom surface than the beams of the traditional frame, which can serve to form a decorative surface together. Furthermore, thanks to the design that the ends of the slide rail 1 are located on the first panel 2 and the second panel 3, only the decorative surface can be seen from inside the vehicle, and the ends of the slide rail 1 will not be exposed, making it more aesthetically pleasing.

[0048] Traditional insect nets have a decorative panel pasted on the bottom of the frame. For some off-road vehicles with insect nets installed, this extra decorative panel often falls off. This solution eliminates the need to add a decorative panel after the slide rail 1 is assembled with the first panel 2 and the second panel 3. This not only saves on the decorative panel but also avoids the problem of the decorative panel falling off.

[0049] Better, such as Figure 2 , Figure 5 , Figure 6 A baffle 21, a reinforcing rib 22, and a limiting plate 23 are fixed on the upper surface of the first panel 2. The baffle 21, the reinforcing rib 22, and the limiting plate 23 are all distributed along the length of the first panel 2, and the reinforcing rib 22 is located between the baffle 21 and the limiting plate 23. A first notch 101 is provided at one end of the bottom of the slide rail 1. The first notch 101 penetrates the inner and outer sides of the slide rail 1. When the first panel 2 is assembled with the slide rail 1, the baffle 21, the reinforcing rib 22, and the limiting plate 23 on the first panel 2 are all placed in the first notch 101.

[0050] Among them, the reinforcing rib 22 is used to improve the strength of the first panel 2; the distance between the baffle 21 and the limiting plate 23 is adapted to the width of the first notch 101. When the baffle 21 and the limiting plate 23 are inserted into the first notch 101, they can play a lateral limiting role, and also facilitate the accurate positioning of the screw holes on the first panel 2 and the slide rail 1 when the first panel 2 is screwed and installed; when the curtain 6 is pulled to one end of the slide rail 1, there is often a gap between it and the upper surface of the first panel 2, resulting in light leakage and an unsightly appearance. The baffle 21 set in this solution can be used to make up for this light leakage defect; moreover, the baffle 21 is L-shaped, including a vertical part 211 and a horizontal part 212. The horizontal part 212 is formed by the top end of the vertical part 211 extending towards the outside of the frame. The horizontal part 212 can prevent the top end of the vertical part 211 from scratching and damaging the curtain 6.

[0051] Moreover, the first panel 2 is integrally formed with the baffle 21, the reinforcing rib 22, and the limiting plate 23, which makes the first panel 2 integrate multiple functions and convenient to produce and install.

[0052] Better, such as Figure 6 A first groove 102 is formed at one end of the bottom surface of the slide rail 1, and a first notch 101 is located in the first groove 102. The end of the first panel 2 is installed in the first groove 102. At this time, the baffle 21 and the limiting plate 23 on the first panel 2 are inserted into the first notch 101, and the bottom surface of the first panel 2 is flush with the bottom surface of the slide rail 1. Figure 2 , Figure 7 A second groove 103 is formed at the other end of the bottom surface of the slide rail 1. The end of the second panel 3 is installed in the second groove 103, and the bottom surface of the second panel 3 is flush with the bottom surface of the slide rail 1.

[0053] The first groove 102 and the second groove 103 on the slide rail 1 can be formed by removing the bottom plate at that end of the slide rail to create the grooves, such as... Figure 6 , Figure 7 It can also be a groove formed by the recessed extension of the bottom plate at this end of the slide rail, or other existing technologies, as long as it facilitates the installation of the first panel and the second panel and keeps the bottom surfaces of the three panels flush.

[0054] By aligning the bottom surfaces of the slide rail 1 (i.e., the bottom surface of the base plate 11), the first panel 2, and the second panel 3, the decorative surfaces can be made flush, resulting in a more aesthetically pleasing finish. Furthermore, this reduces the overall height of the frame. Compared to traditional insect nets that attach decorative panels to the frame, this solution also reduces the space occupied by the insect nets inside the vehicle.

[0055] It should be noted that the text describes the three components as having flush bottom surfaces. However, in actual manufacturing, due to manufacturing or assembly errors, there may be slight unevenness or additional protrusions of varying heights on the bottom surfaces. All of these situations fall within the scope of the flush bottom surfaces described in this solution.

[0056] The structure of the slide rail 1 described above is as follows: Figure 4 :

[0057] In addition to the base plate 11, the slide rail 1 also has a U-shaped wall 12 with an overall inverted U-shaped cross-section extending upward from the upper surface of the base plate 11. The base plate 11 and the U-shaped wall 12 together enclose a first closed cavity 121 with an overall square cross-section. When the slide rail 1 is assembled with the connecting mold base 93, if the first groove or the second groove is formed by removing the base plate at that end, the inner cavity of the U-shaped wall 12 is used to install the third mounting leg 932 of the connecting mold base. If the first groove or the second groove is formed by the indentation of the base plate at that end, the first closed cavity 121 can be used to install the third mounting leg of the connecting mold base. The top surface of the U-shaped wall 12 is recessed downward to form a transition wall 13 with a W-shaped cross-section. By forming it in a downward recessed manner, the overall height can be reduced.

[0058] The first end face (i.e., the left end face of the left side portion 131) at one end of the transition wall 13 and the second end face (i.e., the middle end face) at the middle end extend upwards respectively to form a first inclined wall 133 and a second inclined wall 134. After the top of the first inclined wall 133 intersects with the top of the second inclined wall 134, a transverse wall 135 continues to extend. The first inclined wall 133, the second inclined wall 134, and the left side portion 131 of the W-shaped transition wall 13 enclose a second closed cavity 136. The first inclined wall 133 extends a protrusion 137 toward the second closed cavity 136. The protrusion 137 and the left side portion 131 of the transition wall 13 enclose an arc-shaped first mounting cavity 138 at the lower part of the second closed cavity 136. The first mounting cavity 138 can be used to accommodate the flexible shaft 91 and allow the flexible shaft to move within the cavity. Moreover, the inclined design of the first inclined wall 133 and the second inclined wall 134 can reduce the overall height of the slide rail 1.

[0059] The third end face of the other end of the transition wall 13 (i.e., the right end face of the right side portion 132) extends upward into a bent wall 14. This bent wall 14 is located below the aforementioned transverse wall 135 and forms a gap cavity 141 with an opening facing the inside of the slide rail 1 between it and the transverse wall 135. This gap cavity 141 communicates with the second mounting cavity 139, allowing the sliding portion 71 located at the end of the pull rod 7 to move. Figure 12 .

[0060] Meanwhile, the second inclined wall 134, the right side portion 132 of the W-shaped transition wall 13, and the bent wall 14 together form an arc-shaped second mounting cavity 139. This second mounting cavity 139 can be used to accommodate the flexible shaft 91 and allow the flexible shaft to move within the cavity, such as... Figure 12 The first mounting cavity 138 and the second mounting cavity 139 described above can use an arc-shaped design to radially constrain the sidewalls of the flexible shaft 91, which has a circular cross-section, to prevent the flexible shaft 91 from bending, while also serving as a movement guide.

[0061] Meanwhile, a third mounting cavity 15 with an opening facing the inside of the slide rail 1 is formed between the top surface on the right side of the bent wall 14 and the top surface on the right side of the U-shaped wall 12 (i.e., the top surface on the right side of the transition wall). The third mounting cavity 15 allows the side edge strip of the curtain 6 to move inside it, thus placing the side edge of the curtain 6 inside the slide rail 1 and avoiding the leakage caused by the lateral gap between the curtain 6 and the slide rail 1.

[0062] The top surface of the right side of the U-shaped wall 12, the bent wall 14, and the transverse wall 135 are arranged vertically in sequence at intervals. Based on the concave formation of the W-shaped transition wall and the inclined design of the first inclined wall 133 and the second inclined wall 134, which reduces the height of the transverse wall 135, the top surface of the right side of the U-shaped wall 12 is designed to be lower than the top surface of the left side (i.e., the top surface located on the left side of the transition wall). This reduces the height of the bent wall 14. While fully ensuring the usable space height of the gap cavity 141 and the third mounting cavity 15, it further reduces the overall height of the slide rail 1, saving interior space.

[0063] Furthermore, the inner side of the bent wall 14 extends downward to form a hook 142, which bends toward the third mounting cavity 15. The hook 142 can be used to form a lateral constraint on the edge strip to prevent the side of the curtain 6 from falling laterally off the slide rail 1, and can also improve the lateral tension of the curtain 6.

[0064] Even better, the aforementioned U-shaped wall 12 is located on one side of the base plate 11, and a bent portion 16 extends upward from the other side of the upper surface of the base plate 11. The bent portion 16 and the upper surface of the base plate 11 enclose a fourth mounting cavity 161 with an opening facing the inside of the slide rail 1. The fourth mounting cavity 161 can be used to install ambient lights.

[0065] Furthermore, the bending portion 16, together with the aforementioned U-shaped wall 12 and base plate 11, forms a fifth mounting cavity 17 with an upward opening. This fifth mounting cavity 17 can be used to install the support legs of the base 4 at the end to realize the assembly of the slide rail 1 and the base 4, and can be used to install ambient lights, etc. in the middle.

[0066] The first mounting cavity 138, the second mounting cavity 139, the third mounting cavity 15, the gap cavity 141, the fourth mounting cavity 161, and the fifth mounting cavity 17 are integrated on a slide rail 1, giving the slide rail 1 multiple functions. Furthermore, the first mounting cavity 138, the second mounting cavity 139, the gap cavity 141, and the third mounting cavity 15 work together to improve the overall motion coordination between the flexible shaft 91, the sliding part 71 at the end of the pull rod 7, and the curtain 6.

[0067] It should be noted that the usage of the first mounting cavity 138, the second mounting cavity 139, the third mounting cavity 15, the gap cavity 141, the fourth mounting cavity 161, and the fifth mounting cavity 17 in other embodiments should not be limited to the usage of this embodiment, as long as it is a reasonable assembly and usage method that can be implemented by those skilled in the art.

[0068] The structure of the base 4 described above is as follows: Figures 7 to 9 :

[0069] The outer side wall of the base 4 has a connecting part 41, which is used to install the connecting part 41 on the top surface of the left side of the U-shaped wall 12 of the slide rail 1 by screws, thereby realizing the fixed connection between the base 4 and the slide rail 1; moreover, the bottom surface of the base 4 has an avoidance groove 42 corresponding to the first inclined wall 133 of the slide rail 1, thereby reducing the overall height of the base 4 after it is installed on the slide rail 1; one end of the inner side wall of the base 4 has a rotating hole 43, which is used to rotatably assemble with the end of the scroll 5. Of course, in other embodiments, a rotating groove can be used instead of a rotating hole to rotatably engage with the end of the scroll; a connecting post 44 is formed in the middle of the inner side wall of the base 4, which is used to connect with the pressure strip 8.

[0070] Moreover, such as Figure 8 A guide seat 45 is formed on the lower part of the inner side wall of the base 4, and a first mounting foot 451 is formed at the end of the guide seat 45. The first mounting foot 451 is inserted into the fifth mounting cavity 17 of the slide rail 1 to realize the assembly of the base 4 and the slide rail 1. At the same time, an inclined guide part 452 with a certain slope is formed at the end of the guide seat 45. After the base 4 and the slide rail 1 are assembled, the inclined guide part 452 corresponds to the top surface of the right side of the U-shaped wall 12 of the slide rail 1, which facilitates the smooth introduction of the curtain 6 into the third mounting cavity 15 of the slide rail 1 and prevents the curtain 6 from being scratched and damaged by the end face of the slide rail when it enters the slide rail 1.

[0071] Furthermore, a hook seat 46 is formed at the other end of the inner wall of the base 4. The hook seat 46 is located above the guide seat 45, and a hook 461 is formed on the side of the hook seat 46. The hook 461 is used to cooperate with the inclined guide part 452. When the base 4 is assembled with the slide rail 1, the hook 461 corresponds to the hook part 142 of the slide rail 1. Figure 8When the curtain fabric 6 is guided into the slide rail 1 along the inclined guide part 452, the hook 461 is used to hook the side edge strip of the curtain fabric 6, smoothly guiding the edge strip into the slide rail 1 and being further constrained by the hook part 142.

[0072] Furthermore, a second mounting leg 462 is formed at the end of the hook seat 46 for insertion into the gap cavity 141 of the slide rail 1, thereby realizing the assembly of the hook seat 46 and the slide rail 1.

[0073] The aforementioned guide seat 45, connecting column 44, and hook seat 46 can all be integrally formed with the base 4. Alternatively, the hook seat 46 can be detachably assembled with the base 4. For example, an installation groove 47 can be opened at the other end of the inner side wall of the base 4, and the hook seat 46 can be installed in the installation groove 47 with screws. The detachable design makes it easy to first hang the folded edge strip of the curtain on the hook 461, and then fix the hook seat 46 in the installation groove 47 with screws. Compared with the integrated design of the hook seat and the base, it can reduce the difficulty of hanging the folded edge strip and reduce the complexity of mold opening.

[0074] The assembly relationship between the base 4 and the slide rail 1 is as follows: Figures 7 to 10 :

[0075] The other end of the slide rail 1 (i.e., the end corresponding to the second panel) has a second notch 104 on its inner side. The base 4 is placed above the end of the other end of the slide rail 1, so that the connecting part 41 is located on the top surface of the left side of the U-shaped wall 12 of the slide rail 1 and is fixed together with screws. The first inclined wall 133 of the slide rail 1 is placed in the relief groove 42 of the base 4, and the guide seat 45 is placed in the second notch 104. The first mounting leg 451 of the guide seat 45 is inserted into the fifth mounting cavity 17, and the second mounting leg 462 of the hook seat 46 is inserted into the gap cavity 141. The connecting part 41 is fixed to the top surface of the left side of the U-shaped wall 12 with screws, thereby realizing the assembly of the base 4 and the slide rail 1.

[0076] The assembled base 4 is positioned above the second panel 3, and the second panel 3, the end of the slide rail 1, and the base 4 are arranged vertically in a stacked manner. By utilizing the cooperation of the second notch and the guide seat, the base does not need to be connected to the end face of the slide rail along the length of the slide rail, thereby shortening the total length of the slide rail and reducing the space occupied by the insect screen inside the vehicle.

[0077] Even better, a vertical folded edge 31 is formed on the inner side of the second panel 3 (e.g., Figure 2 The vertical folded edge 31 can be used to reduce the gap between the upper surface of the second panel 3 and the curtain 6 to compensate for light leakage defects. At the same time, when installing the second panel 3 and the second groove 103 of the slide rail 1, the vertical folded edge 31 can be used to abut against the end face of the corresponding second notch 104 of the slide rail 1 to facilitate the installation and positioning of the second panel 3.

[0078] Frame assembly mechanism, such as Figure 1 , Figure 2 :

[0079] The two slide rails 1, together with the first panel 2 and the second panel 3, form a frame within which the curtain 6 can open and close. The first panel 2 and the second panel 3 also improve the stability of the frame. A base 4 is then installed at the other end of the slide rail 1, which can be used to assemble the roller 5, thus forming a frame assembly that can be used to assemble the roller 5 and the curtain 6.

[0080] The assembly relationship between the frame assembly and the roller 5, curtain 6, and pull rod 7 is as follows: Figure 1 , Figure 2 :

[0081] The two ends of the aforementioned scroll 5 are rotatably mounted in the rotation holes 43 of the base 4, so that the scroll 5 can be rotatably mounted between the two bases 4.

[0082] A pressure strip 8 is inserted between the connecting posts 44 of the two bases 4. The pressure strip 8 is used to prevent the curtain 6 from sticking up and to change the height of the curtain 6 unfolded from the roller 5 so that it can be smoothly guided into the third mounting cavity 15 of the slide rail 1.

[0083] The aforementioned pull rod 7 has a sliding part 71 formed at each end. The sliding part 71 can be a slider (such as a slider) separately installed at both ends of the pull rod 7. Figure 12 In other embodiments, it can also be integrally formed with the pull rod 7. The sliding portions 71 at both ends are slidably mounted in the gap cavities 141 of the slide rails 1 on both sides. More preferably, the sliding portion 71 can also have a limiting post portion 72 corresponding to the arc shape of the second mounting cavity 139. The limiting post portion 72 is used to connect to a flexible shaft 91 described below, and at the same time, the limiting post portion 72 is slidably mounted in the second mounting cavity 139 and constrained to prevent the sliding portion 71 from falling laterally off the slide rail 1.

[0084] The unfolding and rolling of the aforementioned insect-proof netting can be done manually or electrically.

[0085] The following example uses electric operation to illustrate an implementation scheme, such as... Figure 1 , Figure 2 , Figure 10 , Figure 11 :

[0086] An electric drive assembly for driving the sliding part 71 of the pull rod 7 to reciprocate within the slide rail 1 is installed on one side of the frame assembly corresponding to the base. This electric drive assembly is on the same side as the scroll 5 and is located above the second panel 3. Of course, in other embodiments, the electric drive assembly can also be placed on the opposite side of the scroll, and the assembly relationship between the electric drive assembly and the slide rail, panel, etc., can be adapted accordingly.

[0087] Moreover, the base 4 is also located above the second panel 3. The vertical folded edge 31 of the second panel 3 abuts against the end face of the slide rail 1 corresponding to the second notch 104, so that after the insect net is installed in the vehicle, the electric drive component, the roller 5 and the base 4 will not be visible from inside the vehicle, thus achieving a good decorative effect.

[0088] The electric drive assembly includes a drive motor integrated module 92 and two connecting mold bases 93. The two connecting mold bases 93 are respectively mounted on the two side slide rails 1. Specifically, the connecting mold bases have third mounting feet 932 formed on them. The third mounting feet 932 are inserted into the inner cavity of the U-shaped wall 12. In this embodiment, screws are used to fix the base 4, slide rail 1, and third mounting feet 932 together, and all three are placed on the second panel 3. Figure 10 As shown.

[0089] The two connecting mold bases 93 are respectively connected to the drive motor integrated module 92 via connecting beams 94. The three can be disassembled and assembled via connecting beams 94, realizing modularity and facilitating spacing adjustment. This replaces the traditional three-in-one design, saving mold opening costs and improving applicability to different vehicle models.

[0090] The drive motor integrated module 92 includes a motor, a reducer, a drive wheel that can mesh with the flexible shaft 91, and two flexible shafts 91 passing through the integrated module. The drive wheel meshes with the flexible shaft 91 under the drive of the motor, causing the flexible shaft 91 to move. The technology of this part of the drive motor integrated module 92 driving the two flexible shafts 91 and thus driving the sliding part 71 in the slide rails on both sides to move back and forth is prior art knowledge and will not be described in detail here.

[0091] The connecting mold base 93 has two through slots 931 for the flexible shaft 91 to pass through. One through slot 931 is connected to the second mounting cavity 139 of the slide rail 1, and the other through slot 931 is connected to the first mounting cavity 138 of the slide rail 1. A conduit 95 for the flexible shaft 91 to pass through is connected between the connecting mold base 93 and the drive motor integrated module 92. The conduit 95 is connected to the through slot 931.

[0092] When the insect-proof net needs to be unfolded, the drive motor integrated module 92 drives the forward ends of the two flexible shafts 91 (the end of the flexible shaft connected to the limiting post is called the forward end) to push the sliding part 71 forward in the second mounting cavity 139 of the slide rails on both sides. The guide tube 95 and the second mounting cavity 139 can form a radial constraint on the flexible shafts 91 to prevent bending and ensure the driving effect of the forward driving sliding part 71, thereby causing the pull rod 7 to drive the curtain 6 to unfold. When the insect-proof net needs to be rolled up, the drive motor integrated module 92 drives the forward ends of the two flexible shafts 91 to retreat in the second mounting cavity 139, and the roll 5 automatically rolls up. At this time, the retreat ends of the two flexible shafts 91 (the opposite end of the forward end of the flexible shaft is called the retreat end) move forward in the first mounting cavity 138 of the other slide rail 1. That is, the first mounting cavity 138 provides a space for the retreat ends of the flexible shafts 91 to be accommodated and moved.
