[0001] This utility model relates to the field of electric sunshade technology, and in particular to an integrated direct-drive electric sunshade. Background Technology

[0002] An electric sunshade for a car is an electrically driven sunshade device installed on the sunroof or side window of a car. It uses an electric motor to raise or roll up the curtain to block sunlight, insulate against heat, block ultraviolet rays and protect privacy. It can be controlled by a remote control, voice commands or other means.

[0003] For example, Chinese Patent CN218777394U discloses a highly adaptable electric sunshade assembly, including a left-side support and a right-side support for the front beam. A front main crossbeam is installed between the left-side and right-side supports, and side beams and a rear beam are installed between the two roller blind bases. However, its installation structure is relatively complex, with many parts and a large overall weight. Moreover, its processing and assembly procedures are quite complicated, resulting in high production costs. Utility Model Content

[0004] The purpose of this invention is to provide an integrated direct-drive electric sunshade that eliminates the traditional front and rear beam connection method, and is installed on the ceiling only through an independent support frame on the rear side. This reduces materials, makes the overall structure simpler, and helps to reduce production and assembly costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated direct-drive electric sunshade curtain, comprising a canopy, a frame assembly, and a sunshade curtain assembly disposed on the frame assembly, characterized in that: the frame assembly comprises an independent support frame and guide rails disposed at both ends of the independent support frame, the guide rails being connected to the canopy via an inner edge; the inner edge comprises a support section disposed at one end of the guide rail and a positioning section disposed at the other end of the guide rail, the positioning section being fixedly connected to the independent support frame; a drive motor is disposed on the independent support frame, the drive motor driving the sunshade curtain assembly to move in and out.

[0006] By adopting the above technical solution, the sunshade curtain can be smoothly raised and lowered under the drive of the motor. Traditional sunshade curtains have a complex structure, while this utility model eliminates the front beam and only retains an independent support frame, which reduces the weight of the whole machine and also reduces the material and processing costs.

[0007] The present invention is further configured such that: the inner edge includes two connecting sections integrally formed with the positioning section and the support section; the guide rail is provided with a plastic-coated edge; and the connecting sections are plastic-coated on the outside of the plastic-coated edge.

[0008] By adopting the above technical solution, the connecting section is plastic-coated into the guide rail, which improves the connection strength and assembly accuracy between the guide rail and the ceiling, while reducing friction between metal parts, reducing noise and improving wear resistance.

[0009] The present invention is further configured such that: the outer periphery of the ceiling is wrapped with an outer edge, and both the outer edge and the inner edge are made of polyurethane material.

[0010] By adopting the above technical solution, the outer edge can protect the edge of the canopy, preventing damage to the edge due to friction or impact, while improving the sealing of the canopy. The polyurethane material has good wear resistance and elasticity, which can effectively buffer external impact, and has weather resistance and anti-aging properties, thereby extending the service life of the sunshade assembly.

[0011] The present invention is further configured such that: the positioning segment is provided with a plurality of fixing holes, the fixing holes are encapsulated with a first insert, and the independent support frame is provided with positioning holes corresponding to the first insert.

[0012] By adopting the above technical solution, the first insert is injection molded and fitted into the positioning section, and is precisely connected to the positioning hole on the independent support frame by screws, thereby improving the structural stability of the sunshade assembly.

[0013] The present invention is further configured such that: a pin is provided on the positioning section, and a corresponding waist hole is provided on the independent support frame, and the pin is inserted into the waist hole.

[0014] By adopting the above technical solution, the pin and the waist hole can be quickly assembled and disassembled, while further improving the stability of the connection between the positioning section and the independent support frame.

[0015] The present invention is further configured such that: the positioning segment is provided with a plurality of mounting protrusions extending in a direction away from the support segment, and the mounting protrusions are covered with a second insert.

[0016] By adopting the above technical solution, the second insert is encapsulated in the mounting protrusion and connected to the outer cover by screws, further improving the convenience of assembly.

[0017] The present invention is further configured such that: a plurality of through holes for forming injection molding channels are provided on the plastic-coated edge.

[0018] By adopting the above technical solution, through holes can improve the flow path of molten material during injection molding, ensure a uniform and reliable bond between the plastic-coated edge and the inner edge, avoid local bubbles or delamination, and improve the overall molding quality.

[0019] The present invention is further configured such that: the sunshade assembly includes a roller rotatably mounted on the independent support frame and a sunshade curtain fabric wound on the roller, and a pull cable assembly is connected to the roller; a slider is slidably mounted on the guide rail, one end of the sunshade curtain fabric is connected to the roller, and the other end is connected to a pull rod, and the slider is connected to the pull rod by a mounting pin.

[0020] By adopting the above technical solution, the slider moves smoothly along the direction of the guide rail, ensuring that the sunshade curtain remains taut and straight during the opening and closing process, avoiding deviation and jamming, thereby improving the smoothness of the sunshade curtain's movement.

[0021] The present invention is further configured such that: the cable assembly includes a rotating reel at both ends of the reel, an outer cable and an inner cable connected to both ends of the rotating reel, the rotating reel is provided with a spiral guide groove for the outer cable and the inner cable to wind around, the guide rail is provided with a cable passage groove, the outer cable passes over the guide rail and through the pull rod and then winds back to the rotating reel, and the inner cable passes through the cable passage groove in the guide rail and through the pull rod and then winds back to the rotating reel.

[0022] By adopting the above technical solution, the outer and inner cables can be routed in an orderly manner on the rotating reel, avoiding cable tangling, slippage, or slack. When the outer cable is released and the inner cable is tightened, the sunshade curtain rolls up; when the outer cable is tightened and the inner cable is released, the sunshade curtain unfolds, thus ensuring smooth operation of the sunshade curtain during opening and closing.

[0023] The present invention is further configured such that: the guide rail is connected to the independent support frame by a mounting block, the mounting block is provided with a limiting edge for blocking the slider, the mounting block is provided with a first guide shaft and a second guide shaft, the first guide shaft is higher than the second guide shaft, the outer cable passes above the second guide shaft and the first guide shaft in sequence, and the inner cable passes between the first guide shaft and the second guide shaft.

[0024] By adopting the above technical solution, the installation block can effectively guide the path of the outer and inner cables, avoid the cables from crossing or misaligning during the extension and retraction process, ensure the smooth operation of the sunshade curtain, and improve the durability of the outer and inner cables.

[0025] In summary, this utility model has the following beneficial effects: 1.

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] like Figures 1 to 4As shown, this utility model provides an integrated direct-drive electric sunshade assembly 3, including a canopy 1, a frame assembly 2, and a sunshade assembly 3 mounted on the frame assembly 2. The frame assembly 2 includes an independent support frame 21 and guide rails 22 on both sides of the independent support frame 21. The traditional front beam is eliminated, and the sunshade assembly 3 is supported only by the independent support frame 21. This not only reduces the amount of material used and the processing steps, but also reduces the overall weight, making the entire sunshade system more compact and economical. The independent support frame 21 is horizontally arranged at the rear of the canopy 1, and guide rails 22 are vertically fixed at both ends. The sunshade fabric 32 is wound around the roller. On the shaft 31, the roller 31 is rotatably mounted on the independent support frame 21. A cable assembly is connected to the roller 31. One end of the roller 31 is driven by the drive motor 4. A slider 5 is provided inside the guide rail 22. The slider 5 can move smoothly along the length of the guide rail 22. The end of the sunshade curtain 32 away from the roller 31 is fixed to the pull rod 33. The pull rod 33 and the slider 5 are connected by a mounting pin 51. As the roller 31 rotates, the pull rod 33 moves through the cable assembly. The slider 5 slides synchronously in the guide rail 22. The drive motor 4 drives the roller 31 to rotate through a gear transmission structure, thereby driving the sunshade curtain 32 to roll up or unfold.

[0039] like Figure 8 As shown, the inner edging 9 includes a support section 91 located at one end of the guide rail 22 and a positioning section 92 located at the other end of the guide rail 22. Both ends of the positioning section 92 extend toward the support section 91 and are fixedly connected to the independent support frame 21, thereby ensuring the overall structural stability of the frame assembly 2. The support section 91 is used to support the sunshade assembly 3. The inner edging 9 also includes two connecting sections 93 integrally formed with the support section 91 and the positioning section 92. The connecting sections 93 are arranged along the length direction of the guide rail 22. The positioning section 92 and the support section 91 are respectively transversely connected between the two parallel connecting sections 93, and the positioning section 92 and the support section 91 are also arranged parallel to each other. The positioning section 92, the support section 91 and the connecting sections 93 together form an integrated edging frame structure. This not only provides a stable installation positioning reference for the guide rail 22, but also provides support and limit. The guide rail 22 is provided with a plastic-coated edge 222, and the connecting section 93 covers the outside of the plastic-coated edge 222, thereby forming a high-strength integral injection-molded joint structure. This structure can improve the connection strength between the guide rail 22 and the canopy 1, and reduce the direct friction between metal parts, thereby improving the noise reduction performance of the sunshade system. The outer periphery of the canopy 1 is plastic-coated with an outer edge 8. Both the outer edge 8 and the inner edge 9 are made of polyurethane. Polyurethane material has good wear resistance, elasticity and anti-aging properties. The outer edge 8 can protect and seal the edge of the canopy 1, preventing damage to the edge due to long-term friction or collision, while improving the sealing performance and service life of the sunshade system.

[0040] The positioning section 92 is provided with multiple fixing holes 921, and the fixing holes 921 are encased in plastic with a first insert 922. The independent support frame 21 is provided with positioning holes 211 corresponding to the first insert 922. During installation, the first insert 922 cooperates with the positioning holes 211 to achieve precise positioning and firm fixation between the inner edge 9 and the independent support frame 21, thereby enhancing the overall stability of the frame connection. The positioning section 92 is also provided with a pin 923, and the independent support frame 21 is provided with a corresponding waist hole 212. The pin 923 and the waist hole 212 are inserted and cooperated. This structure facilitates the quick installation and disassembly of the sunshade module and further improves the stability of the connection between the positioning section 92 and the independent support frame 21.

[0041] The positioning section 92 is also provided with a number of mounting protrusions 924 extending away from the support section 91. The mounting protrusions 924 are covered with a second insert 925 and connected to the outer cover by screws, which further improves the convenience of assembly. The plastic-coated edge 222 of the guide rail 22 is provided with a number of through holes 2221. These through holes 2221 can form a melt flow channel during the injection molding process, so that the plastic coating material is evenly coated on the surface of the guide rail 22, avoiding bubbles or delamination, and improving the plastic coating bonding quality and structural durability.

[0042] like Figure 4 and Figure 6 As shown, the roller 31 is also equipped with a winding wheel 7 at both ends. The two ends of the winding wheel 7 are connected to an outer pull cable 71 and an inner pull cable 72. A spiral guide groove is arranged on the winding wheel 7 to guide the winding direction of the outer pull cable 71 and the inner pull cable 72. When the roller 31 rotates under the drive of the motor, the winding wheel 7, through the coordinated winding and unwinding of the outer pull cable 71 and the inner pull cable 72, allows the sunshade curtain 32 to move smoothly along the guide rail 22. The guide rail 22 is provided with a cable guide groove 221. The outer pull cable 71 passes over the guide rail 22 and through the pull rod 33 before returning to the rotating reel 7. The inner pull cable 72 passes through the cable groove 221 in the guide rail 22 and through the pull rod 33 before returning to the rotating reel 7. When the outer pull cable 71 is released and the inner pull cable 72 is tightened, the sunshade curtain 32 rolls up. When the outer pull cable 71 is tightened and the inner pull cable 72 is released, the sunshade curtain 32 unfolds, thus ensuring that the sunshade curtain 32 runs smoothly when it is rolled up and down.

[0043] like Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, the pull rod 33 includes an integrally formed mounting part 331 and a bending part 332. The bending part 332, which bends upwards near the connection point with the sunshade curtain 32, supports the edge of the sunshade curtain 32, ensuring that the front end of the sunshade curtain 32 is firmly fixed and will not fall off or loosen during movement. The mounting part 331 is located at the other end of the bending part 332. A mounting groove 333 is formed within the mounting part 331. The outer pull cable 71 and the inner pull cable 72 are led out from the rotating wheel 7, pass through the mounting groove 333, and are then inserted into the mounting pin 51 on the slider 5. The mounting slot 333 is fixed, and the slider 5 is designed with staggered first guide grooves 52 and second guide grooves 53. The entrance of the first guide groove 52 is away from the side of the reel 31, and the entrance of the second guide groove 53 is close to the side of the reel 31. The outer cable 71 passes through the first guide groove 52, and the inner cable 72 passes through the second guide groove 53. Through this staggered design, the cooperation between the outer cable 71 and the inner cable 72 and the mounting pin 51 is more stable, and their arrangement in the pull rod 33 is more reasonable, which can avoid mutual interference and ensure that the two always run along parallel paths.

[0044] like Figure 5 As shown, in order to further maintain the tension of the outer cable 71 and the inner cable 72, a first tension spring 521 is provided inside the first guide groove 52, and both ends of the outer cable 71 are connected to the first tension spring 521 respectively; a second tension spring 531 is provided inside the second guide groove 53, and both ends of the inner cable 72 are connected to the second tension spring 531. The first tension spring 521 and the second tension spring 531 provide a continuous preload to the cable assembly, so that the outer cable 71 and the inner cable 72 can remain taut, avoiding slippage or transmission problems caused by slackness.

[0045] like Figure 5 As shown, the guide rail 22 is connected to the independent support frame 21 via the mounting block 6. The mounting block 6 is provided with a limiting edge 61 that blocks the slider 5. The mounting block 6 is also provided with a first guide shaft 62 and a second guide shaft 63. The first guide shaft 62 is slightly higher than the second guide shaft 63. When the outer cable 71 passes along the guide rail 22, it first goes around the second guide shaft 63 and then passes over the first guide shaft 62. The inner cable 72 passes between the first guide shaft 62 and the second guide shaft 63 to guide the path of the outer cable 71 and the inner cable 72. This ensures that the outer cable 71 and the inner cable 72 remain clearly separated at the slider 5 and avoids them from getting tangled.

[0046] like Figure 1As shown, the outer perimeter of the canopy 1 is covered with an outer edge 8, and the surface of the guide rail 22 is also provided with an inner edge 9. The inner edge 9 is fixed to the independent support frame 21 by bolts. The outer edge 8 and the inner edge 9 not only play a role in a stable connection, but also enhance the bonding strength between the guide rail 22 and the canopy 1. Polyurethane material is used as the main material for the outer edge 8 and the inner edge 9. Polyurethane has excellent wear resistance and elasticity, which can effectively absorb vibration and external impact. At the same time, it has weather resistance and anti-aging properties, so that the sunshade assembly 3 can maintain reliability and durability during long-term use.

[0047] The basic working principle of this utility model is as follows: First, the sunshade curtain 32, roller 31, cable assembly, pull rod 33, and slider 5 are pre-assembled on the independent support frame 21 to form a complete curtain assembly. The guide rail 22 is covered with a plastic inner edge 9, which is installed on the independent support frame 21 by bolts. Then, the inner edge 9 is attached to the skylight glass of the ceiling 1. When the drive motor 4 starts, the roller 31 rotates on the independent support frame 21, and the rotating wheels 7 at both ends of the roller 31 rotate simultaneously, driving the outer pull cable 71 and the inner pull cable 72 to be rolled up and down in an orderly manner. During the rolling up process of the sunshade curtain 32, As the outer cable 71 gradually releases and the inner cable 72 gradually tightens, the slider 5 slides backward within the guide rail 22, causing the sunshade curtain 32 to smoothly retract along the guide rail 22 towards the roller 31. During the unfolding of the sunshade curtain 32, the roller 31 and the rotating wheel 7 rotate in opposite directions, the outer cable 71 gradually tightens and the inner cable 72 gradually releases, causing the sunshade curtain 32 to unfold along the guide rail 22 towards the front end. The slider 5 slides forward within the guide rail 22, and the sunshade curtain 32 is evenly stretched and laid out flat. Throughout the entire unfolding process, the outer cable 71 and the inner cable 72 remain taut, ensuring a smooth and reliable transmission process.

[0048] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
