[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0033] like Figure 1-7 As shown, this embodiment provides a fully automatic car sunshade system applied to the roof of a car (not shown in the figure). It includes a first rotating component, a second rotating component, and a sunshade cloth 10. The first rotating component and the second rotating component are arranged in parallel and are both installed on the roof of the car. Both the first rotating component and the second rotating component can rotate relative to the roof of the car. The sunshade cloth 10 is wound around the first rotating component, and a pull rope 20 is provided on the first end of the sunshade cloth 10. The pull rope 20 is connected to the second rotating component. When the canopy needs to be closed, the second rotating component can be driven to rotate, so that the second rotating component can wind the pull rope 20, thereby applying a pulling force to the first end of the sunshade cloth 10. Under the pulling force of the pull rope 20, the first rotating component rotates, thereby moving the first end of the sunshade cloth 10 toward the direction of the second rotating component, realizing the unfolding of the sunshade cloth 10 wound on the first rotating component. When the canopy needs to be opened, the first rotating component and the second rotating component rotate in opposite directions, thereby moving the first end of the sunshade cloth 10 toward the direction of the first rotating component, thereby allowing the sunshade cloth 10 to be rewound onto the first rotating component, realizing the storage of the sunshade cloth 10.

[0034] It is understandable that the synchronous rotation of the first rotating component and the second rotating component can better realize the unfolding and storage of the sunshade 10 wrapped on the first rotating component. The unfolding of the sunshade 10 can better block the sunlight from the outside of the car, better avoid the problem of excessive temperature inside the car and high ultraviolet intensity, and improve the comfort of car use.

[0035] Furthermore, in order to improve the aesthetics of the car, the first rotating component, the second rotating component, and the sunshade 10 can all be installed inside the structure of the car roof, without any particular limitation.

[0036] In some embodiments, the first rotating member includes a first bracket 110 fixedly mounted on the vehicle roof and a coil rod 120 rotatably connected to the first bracket 110. Specifically, there are two first brackets 110, and both first brackets 110 are fixedly mounted on the vehicle roof by bolts. An installation shaft 111 extends from the first bracket 110. The two ends of the coil rod 120 are provided with installation holes 121 into which the installation shaft 111 can extend. In the installed state, the two ends of the coil rod 120 are respectively sleeved on the installation shaft 111 on the first bracket 110 at the corresponding position through the installation holes 121, thereby realizing the installation of the coil rod 120 on the vehicle roof, and the sunshade is wound around the coil rod 120.

[0037] It should be noted that since the roller 120 is sleeved on the mounting shaft 111 of the first bracket 110 through the mounting hole 121, there is no rigid connection between the roller 120 and the first bracket 110. The roller 120 can rotate relative to the first bracket 110 through the rotation of the mounting hole 121 on the mounting shaft 111, and thus can cooperate with the second rotating component to realize the unfolding and storage of the sunshade cloth 10.

[0038] More specifically, when the second rotating component rotates and applies tension to the first end of the sunshade cloth 10 through the pull rope 20, the roller 120 can rotate relative to the first bracket 110 and the vehicle roof through the mounting hole 121 and the mounting shaft 111, thereby enabling the first end of the sunshade cloth 10 to move toward the direction of the second rotating component and unfold the sunshade cloth 10; when it is necessary to store the sunshade cloth 10, the roller 120 and the second rotating component can rotate synchronously in opposite directions.

[0039] In some embodiments, a spring system is also provided between the roller 120 and the first bracket 110. When the sunshade cloth 10 is in the unfolded state, the second rotating member reverses, so that the pull rope 20 no longer applies tension to the first end of the sunshade cloth 10. In this state, the spring system can drive the roller 120 to reverse synchronously, thereby realizing the automatic winding of the sunshade cloth 10 by the roller 120 and the automatic storage of the sunshade cloth 10.

[0040] Furthermore, the spring system can be a torsion spring (not shown in the figure) set between the roller 120 and the first bracket 110. When the torsion spring is in the normal extended state, the sunshade cloth 10 is wound on the roller 120, so that the sunshade cloth 10 is in the stored state. When the second rotating member applies a pulling force to the sunshade cloth 10 through the pull rope 20, the roller 120 achieves synchronous rotation with the second rotating member by compressing the torsion spring, thereby realizing the unfolding of the sunshade cloth 10. When the second rotating member rotates in the opposite direction and no longer applies a pulling force to the sunshade cloth 10, the roller 120 will automatically rotate in the opposite direction under the action of the torsion spring, thereby realizing the rewinding of the sunshade cloth 10 and realizing the automatic storage of the sunshade cloth 10.

[0041] Furthermore, the torsion spring is specifically positioned between the mounting hole 121 and the mounting shaft 111, which can better conceal the torsion spring. At the same time, the coil rod 120 and the first bracket 110 can also provide a certain degree of protection for the torsion spring, making the working state of the torsion spring more stable and reliable.

[0042] In some embodiments, the second rotating component includes a second bracket 210 fixedly mounted on the vehicle roof, a drum 220 rotatably connected to the second bracket 210, and a drive motor 230 capable of driving the drum 220 to rotate relative to the second bracket 210. Specifically, two second brackets 210 are provided, and both second brackets 210 are fixedly mounted on the vehicle roof by bolts. Each of the two second brackets 210 is provided with an extended connecting block 211. In the installed state, both ends of the drum 220 can be respectively sleeved on the connecting block 211 of the second bracket 210 corresponding to their positions, thereby realizing the installation of the drum 220 on the vehicle roof, and the pull rope 20 is connected to the drum 220.

[0043] Furthermore, the drive motor 230 is fixedly mounted on one of the second brackets 210, so that the drive motor 230 can be fixedly mounted on the roof of the vehicle body through the second bracket 210. Specifically, the drive motor 230 can be fixedly mounted on the connecting block 211 of the corresponding second bracket 210.

[0044] Furthermore, a piston wheel 212 is provided on the second bracket 210 that is not connected to the drive motor 230. The piston wheel 212 is installed on the connecting block 211 of the second bracket 210, which further extends the connecting block 211. In the installed state, the drum 220 is also sleeved on the piston wheel 212, making the connection between the second bracket 210 and the drum 220 more stable.

[0045] It should be noted that after the drive motor 230 is fixedly installed on one of the second brackets 210, the two ends of the drum 220 are respectively fitted onto the connecting blocks 211 of the two second brackets 210. During this process, the drum 220 also fits the drive motor 230 inside, so that the drive motor 230 can be hidden inside the drum 220. Finally, the two second brackets 210 are fixedly installed on the roof of the vehicle body with bolts. When the canopy needs to be closed, the drive motor 230, fixed to the second bracket 210, operates and drives the drum 220 to rotate relative to the second bracket 210. This allows the drum 220 to wind the pull rope 20, which in turn applies tension to the first end of the sunshade 10. The drum 120 rotates synchronously relative to the first bracket 110 via a compression torsion spring, allowing the first end of the sunshade 10 to move toward the drum 220, thus unfolding the sunshade 10. When the drive motor 230 is turned off, its output shaft cannot rotate freely, thus keeping the drum 220 in its unfolded state and preventing circumferential rotation. When the canopy needs to be opened, the drive motor 230 works and drives the roller 220 to rotate in the opposite direction, thereby releasing the tension on the first end of the sunshade cloth 10. During this process, the roller 120 will rotate in the opposite direction synchronously under the action of the torsion spring, so that the roller 120 can rewind the sunshade cloth 10 and realize the storage of the sunshade cloth 10.

[0046] In some embodiments, the second rotating member further includes a fixing block 240. In the installed state, the fixing block 240 can be fixedly connected to the inner wall of the drum 220 and the output shaft of the drive motor 230 respectively, thereby preferably realizing the indirect fixing of the output shaft of the drive motor 230 to the inner wall of the drum 220 through the fixing block 240, so that when the output shaft of the drive motor 230 rotates, it can synchronously drive the drum 220 to rotate through the fixing block 240, thereby preferably realizing the drive of the drive motor 230 to drive the drum 220.

[0047] Furthermore, to facilitate the installation of the fixing block 240 with the drum 220 and the drive motor 230, the fixing block 240 can be fixedly installed inside the drum 220 by bolts, adhesive or interference fit, and the fixing block 240 and the output shaft of the drive motor 230 can be fixedly connected by plug-in, snap-fit ​​or adhesive, thereby facilitating disassembly and use.

[0048] In some embodiments, a plurality of limiting rings 221 are provided on the circumferential outer wall of the drum 220, and a pull rope 20 is fixedly connected between two adjacent limiting rings 221, so that when the canopy needs to be closed, the pull rope 20 can be wound around the side wall of the drum 220 between two adjacent limiting rings 221 during the rotation of the drum 220.

[0049] Understandably, the setting of the limiting ring 221 can effectively limit the pull rope 20 during the winding process of the drum 220, prevent the pull rope 20 from falling off the drum 220, and improve the overall stability of the system.

[0050] In some embodiments, the drive motor 230 is a tube motor, which can be better concealed inside the drum 220.

[0051] In some embodiments, a ring-shaped support block 231 is provided on the circumferential outer wall of the drive motor 230. Since the drive motor 230 needs to drive the drum 220 to rotate during operation, a gap needs to be maintained between the drive motor 230 and the inner wall of the drum 220 to ensure smooth driving of the drum 220 by the drive motor 230. In the installed state, the support block 231 on the drive motor 230 further reduces the gap between the drive motor 230 and the inner wall of the drum 220. This allows the drive motor 230 to support the drum 220 through the support block 231 when the drum 220 is unstable, without affecting the smooth driving of the drum 230, thus preventing significant shaking of the drum 220 and maintaining the stability of the overall system.

[0052] In some embodiments, a guide member 300 is provided between the first rotating member and the second rotating member. The guide member 300 extends from the first rotating member toward the second rotating member. A guide wheel 310 is provided on the guide member 300. The first end of the sunshade cloth 10 and the pull rope 20 of the roller 220 are attached to the guide wheel 310.

[0053] It should be noted that the guide component 300 is fixedly installed on the roof of the vehicle body, while the guide wheel 310 can rotate relative to the guide component 300. Placing the pull rope 20 on the guide wheel 310 can better prevent the pull rope 20 from rubbing against the side walls of other components and causing damage to the pull rope 20. At the same time, since the guide wheel 310 can rotate, it can play a certain role in conveying the pull rope 20, making the movement of the pull rope 20 smoother.

[0054] In some embodiments, a baffle 320 is provided at the end of the guide member 300 near the second rotating member. The baffle 320 extends to a position near the second rotating member. Specifically, the baffle 320 extends to a position near the circumferential outer wall of the drum 220.

[0055] It is understandable that by setting a baffle 320 between the guide 300 and the drum 220, the baffle 320 can play a certain guiding and protective role for the pull rope 20, making the movement of the pull rope 20 between the sunshade cloth 10 and the drum 220 more stable, and at the same time preventing other parts from touching the pull rope 20, making the movement of the pull rope 20 safer.

[0056] In some embodiments, a connecting piece 11 is provided on the first end of the sunshade cloth 10, and a guide block 12 is provided on the connecting piece 11. The pull rope 20 is fixedly connected to the guide block 12 to realize the connection between the pull rope 20 and the first end of the sunshade cloth 10.

[0057] Furthermore, the connecting piece 11 and the guide block 12 can be fixed by welding, snap-fitting, bonding or bolting, etc., without any particular limitation.

[0058] In some embodiments, a guide groove 330 is provided on the guide member 300, which extends along the length direction of the guide member 300. In the installed state, both the connecting piece 11 and the guide block 12 extend into the guide groove 330, so that the guide member 300 can guide the movement of the connecting piece 11 and the guide block 12, thereby improving the stability of the sunshade cloth 10 during unfolding and storage.

[0059] Furthermore, the guide wheel 310 can be set in the guide groove 330, which can better hide the guide wheel 310. At the same time, after the guide wheel 310 is set in the guide groove 330, the guide block 12 also extends into the guide groove 330, so that the pull rope 20 can be placed on the guide wheel 310, which can better hide and protect the pull rope 20.

[0060] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
