[0029] Please see Figures 1 to 6 This embodiment provides a car sunshade with a built-in direct drive motor 241, which includes a frame 1 and a roller blind device 2 disposed on the frame 1. The frame 1 is provided with a light-transmitting area, and the roller blind device 2 can raise and lower the sunshade curtain 22 to open or block the light-transmitting area.

[0030] Specifically, the roller blind device 2 described in this embodiment includes a winding roller shaft 21, a sunshade curtain 22, a curtain rod 23, and a winding assembly. The winding roller shaft 21 is rotatably mounted on the frame 1 and is used to automatically wind up the sunshade curtain 22. The winding roller shaft 21 can be an automatic roller shaft commonly used for winding up curtains in the prior art. In its natural state, the winding roller shaft 21 has the function of winding up the sunshade curtain 22. One side of the sunshade curtain 22 is connected to the take-up roller shaft 21, and the other side is connected to the curtain rod 23. Both ends of the curtain rod 23 are slidably connected to the frame 1. The curtain rod 23 can slide on the frame 1 to approach or move away from the take-up roller shaft 21. When the curtain rod 23 slides away from the take-up roller shaft 21, the sunshade curtain 22 can be unfolded to block the light-transmitting area. When the curtain rod 23 slides close to the take-up roller shaft 21, the sunshade curtain 22 is rolled up by the take-up roller shaft 21, thus opening the light-transmitting area.

[0031] A tension spring 231 is provided in the middle of the curtain rod 23. A winding assembly is provided at each end of the take-up roller shaft 21. Each winding assembly includes a direct drive motor 241, a winding wheel 242, and a guide wheel assembly 243. The direct drive motor 241 is built into the end of the take-up roller shaft 21. The winding wheel 242 is connected to the output shaft 2411 of the direct drive motor 241. A rope 2420 is wound on the winding wheel 242. The guide wheel assembly 243 is arranged on the frame 1 and the curtain rod 23. The end of the rope 2420 passes through the guide wheel assembly 243 and is connected to the tension spring 231. The two ends of the tension spring 231 are respectively connected to the ropes 2420 of the two winding assemblies. The tension spring 231 can tighten the ropes 2420 at both ends to prevent the ropes 2420 from becoming loose.

[0032] In this embodiment, the direct drive motor 241 drives the winding reel 242 to wind up the rope 2420, thereby causing the curtain rod 23 to slide away from the take-up roller shaft 21, thus unfolding the sunshade curtain 22 to block the light-transmitting area. It can be understood that when the direct drive motor 241 releases the rope 2420 by driving the winding reel 242, the rope 2420 is tightened by the tension spring 231 to prevent it from loosening, and the take-up roller shaft 21 continuously winds up the sunshade curtain 22, causing the curtain rod 23 to move closer to the take-up roller shaft 21, opening up the light-transmitting area to allow light to pass through.

[0033] As can be seen from the above configuration, the car sunshade of this embodiment has a reasonable structural design. The direct drive motor 241 is built into the winding roller shaft 21, reducing the space occupied. The direct drive motor 241 drives the winding wheel 242 to wind or release the rope 2420, thereby enabling the sunshade curtain 22 to unfold or roll up. Its transmission process is simple, maintenance costs are low, and it is conducive to widespread use. The car sunshade of this embodiment simplifies the drive structure of the sunshade, reduces the overall thickness of the sunshade, and improves the headroom for passengers in the vehicle. The motor directly drives the opening and closing, eliminating the need for traditional gears or connecting rods, significantly simplifying the structure and reducing the failure rate.

[0034] Among them, the sunshade curtain 22 uses high-strength fiber composite fabric, which reduces the overall weight and reduces the motor load.

[0035] In this embodiment, two roller blind devices 2 are symmetrically arranged, and the light-transmitting area is opened or blocked by the two roller blind devices 2. Of course, in some other embodiments, only one roller blind device 2 may be provided.

[0036] Specifically, the guide wheel assembly 243 in this embodiment includes a first guide wheel 2431 disposed on the frame 1 and a second guide wheel 2432 disposed at the end of the curtain rod 23. The rope 2420 first passes around the first guide wheel 2431 and then around the second guide wheel 2432. The second guide wheel 2432 is located between the first guide wheel 2431 and the take-up roller shaft 21. With this arrangement, when the winding wheel 242 winds up the rope 2420, it drives the curtain rod 23 to slide away from the take-up roller shaft 21.

[0037] Preferably, the frame 1 is provided with guide rails 11 located at both ends of the curtain rod 23, and the two ends of the curtain rod 23 are provided with sliding blocks 232 that are slidably engaged with the guide rails 11, so that the engagement is more stable.

[0038] Preferably, the frame 1 is provided with a support 12 for supporting the output shaft 2411 of the direct drive motor 241, which facilitates installation. Furthermore, the end of the guide rail 11 is provided with a mating groove, and the support 12 is provided with a mating protrusion 121 that is inserted into the mating groove. This arrangement facilitates disassembly and subsequent inspection and maintenance.

[0039] Preferably, the curtain rod 23 is provided with a groove 233 for accommodating the rope 2420 and the tension spring 231. This avoids exposing the rope 2420 and the tension spring 231.

[0040] Preferably, the curtain rod 23 is provided with a grip 234, which facilitates manual operation of the curtain rod 23 by the user.

[0041] Preferably, a control switch 13 is provided on the frame 1, and the control switch 13 is electrically connected to the direct drive motor 241. By operating the control switch 13, the working state of the direct drive motor 241 can be controlled.
