[0037] Figure 1 This is a schematic diagram of the structure of an integrated device 100 for a canopy shading system and a projection screen, provided in an embodiment of this application. Figure 1As shown, this application embodiment provides an integrated device 100 for a canopy shading system and a projection screen, including a canopy shading device 10, a screen assembly 20, a screen assembly moving component 30, and two screen wiring harness management components 40.

[0038] The awning shading device 10 can be any existing awning shading device with awning unfolding and retracting functions, but it must include at least an awning frame 11 as the mounting base for the curtain assembly 20, the curtain assembly moving assembly 30, and the curtain wiring harness management assembly 40. As an example, such as... Figure 2 As shown, the canopy frame 11 is rectangular and includes a front crossbeam 111, a rear crossbeam 112, and two side beams 113. One side beam 113 connects the left end of the front crossbeam 111 and the left end of the rear crossbeam 112, and the other side beam 113 connects the right end of the front crossbeam 111 and the right end of the rear crossbeam 112.

[0039] The screen assembly 20 can be any existing screen assembly with screen unfolding and retracting functions, but it must have at least the following structure: such as Figure 3 As shown, the top of the curtain assembly 20 is provided with connecting seats 21 at both ends of the vehicle's horizontal direction. The connecting seats 21 are provided with first connecting holes 211, which are used to connect with the slider 33 of the curtain assembly moving component 30 in conjunction with fasteners.

[0040] The curtain assembly moving component 30 is mounted on the canopy frame 11 and connected to the curtain assembly 20. The curtain assembly moving component 30 is used to drive the curtain assembly 20 to move along the two side beams 113 of the canopy frame 11. The curtain assembly moving component 30 includes a motor 31, two flexible shafts 32, and two sliders 33.

[0041] The motor 31 can be mounted on the front crossbeam 111 or the rear crossbeam 112 of the canopy frame 11. The output end of the motor 31 is connected to an output gear, which meshes with two flexible shafts 32 to drive the two flexible shafts 32 to move along their respective axial directions. As an example, such as... Figure 2 As shown, motor 31 is mounted on front crossbeam 111. Further, as... Figure 4 As shown, the motor 31 can be snapped onto the front crossbeam 111 using plastic clips 311. Both the housing of the motor 31 and the front crossbeam 111 have clip holes that mate with the plastic clips 311. This installation method enables the motor 31 to be quickly installed onto the front crossbeam 111, making the operation very convenient.

[0042] Two flexible shafts 32 are mounted on the canopy frame 11 and driven synchronously by a motor 31. As an example, the front crossbeam 111 has two first flexible shaft guide grooves extending along the extension direction of the front crossbeam 111; such as... Figures 5 to 7As shown, each side beam 113 is provided with a second flexible shaft guide groove 1131 extending along the extension direction of the side beam 113. The second flexible shaft guide grooves 1131 of the two side beams 113 are respectively connected to two first flexible shaft guide grooves. Two flexible shafts 32 are respectively installed in the two first flexible shaft guide grooves. One flexible shaft 32 extends into the second flexible shaft guide groove 1131 of one side beam 113, and the other flexible shaft 32 extends into the second flexible shaft guide groove 1131 of the other side beam 113. Both flexible shafts 32 mesh with the output gear and are respectively arranged on both sides of the output gear of the motor 31. When the motor 31 drives the output gear to rotate forward or backward, the two flexible shafts 32 move synchronously along the corresponding flexible shaft guide grooves.

[0043] Two sliders 33 are respectively mounted on the two side beams 113 of the canopy frame 11 and are respectively connected to two flexible shafts 32. The two flexible shafts 32 drive the sliders to move along the two side beams 113, thereby moving the curtain assembly 20 along the two side beams 113. As an example, such as... Figures 5 to 7 As shown, each side beam 113 is provided with a slider guide groove 1132 extending along the extension direction of the side beam 113. The slider guide groove 1132 is parallel to and connected to the second flexible shaft guide groove 1131 of the side beam 113. The cross-section of the slider guide groove 1132 is a T-shaped groove with the opening facing downwards. Two sliders 33 are respectively installed in the slider guide grooves 1132 of the two side beams 113. Figure 8 and Figure 9 As shown, the slider 33 includes a plastic slider body 331 and a metal connector 332. The plastic slider body 331 is made of nylon, polytetrafluoroethylene or other self-lubricating plastics, and the metal connector 332 is made of stainless steel, aluminum alloy or other high-strength metal materials. The plastic slider body 331 and the metal connector 332 are integrated by an inlay injection molding process, which takes into account both self-lubrication and strength requirements.

[0044] The plastic slider body 331 includes a base 3311 and a flexible shaft connecting part 3312. The base 3311 is disposed in the slider guide groove 1132 and the cross-section of the base 3311 is T-shaped. The T-shape has good guiding stability and anti-detachment properties. The top surface and one side wall of the base 3311 are formed with elastic guide plates 33111 that contact the groove wall of the slider guide groove 1132. The elastic guide plates 33111 are used to compensate for the gap between the base 3311 and the groove wall of the slider guide groove 1132 when the slider 33 slides through elastic deformation, so as to ensure the smoothness of the slider 33 sliding. The flexible shaft connecting part 3312 is connected to the other side wall of the base 3311 and disposed in the second flexible shaft guide groove 1131. The flexible shaft connecting part 3312 can be connected to one end of the flexible shaft 32 by thread, covering or other connection methods. The metal connector 332 is plate-shaped and connects to the T-shaped vertical portion of the cross-section of the base 3311. The metal connector 332 has a second connection hole 3321. Figure 10As shown, the second connection hole 3321 of the metal connector 332 is engaged with the first connection hole 211 on the connector seat 21 of the curtain assembly 20 by a fastener, so as to realize the connection between the metal connector 332 and the curtain assembly 20. The number of the first connection hole 211 and the second connection hole 3321 can both be two and are distributed along the extension direction of the slider guide groove 1132.

[0045] like Figure 1 and Figure 2 As shown, each side beam 113 is provided with a curtain wiring harness management assembly 40. Each curtain wiring harness management assembly 40 includes a tank chain bracket 41 and a tank chain 42. The tank chain bracket 41 is mounted on the side beam 113 and has a chain groove for accommodating the tank chain 42. The tank chain 42 is disposed in the chain groove of the tank chain bracket 41. One end of the tank chain 42 is connected to the slider 33, and the other end of the tank chain 42 is connected to the side beam 113. An electrical wiring harness 22 connected to the curtain assembly 20 is disposed inside the tank chain 42. The tank chain 42 provides guidance and protection for the electrical wiring harness 22.

[0046] As an example, such as Figure 6 , Figure 11 and Figure 12 As shown, the tank track bracket 41 is a long component extending along the bottom of the side beam 113. Both ends of the tank track bracket 41 have latches 411, which engage with corresponding latch holes at the bottom of the side beam 113. This installation method allows for quick installation of the tank track bracket 41 to the side beam 113. Multiple connecting feet 412 are distributed along the top of the tank track bracket 41 in the extending direction. Each connecting foot 412 extends laterally outward from the vehicle and is connected to the mounting surface 1133 formed by fasteners on the outer wall of the side beam 113, ensuring a stable connection between the tank track bracket 41 and the side beam 113. Figure 8 , Figure 9 and Figure 12 As shown, one end of the tank chain 42 is connected to the third connecting hole 3322 on the metal connector 332 of the slider 33 via a fastener. The other end of the tank chain 42 is connected to the mounting surface 1133 formed by the outer wall of the side beam 113 via a fastener and connector 421. The metal connector 332 of the slider 33 is also provided with a wire harness through hole 3323 through which the electrical wire harness 22 passes. When the slider 33 of the curtain assembly moving component 30 drives the curtain assembly 20 to move along the side beam 113, the tank chain 42 moves with the slider 33 in the chain groove of the tank chain bracket 41, and the electrical wire harness 22 moves with the tank chain 42 to prevent the electrical wire harness 22 from getting tangled or damaged during the movement.

[0047] In addition, such as Figure 1 , Figure 2 and Figure 12 As shown, each tank track bracket 41 has multiple latches 50 distributed along its extension direction at its bottom. The latches 50 are used to engage with corresponding latches on the vehicle roof to achieve rapid installation of the integrated device 100 of the awning sunshade system and projection screen onto the vehicle roof. For example, the latches 50 are mushroom-shaped latches. Figure 12 As shown, a positioning pin 1134 is also formed on the mounting surface 1133 formed on the outer side wall of each side beam 113. The positioning pin 1134 is used to connect with the positioning hole on the roof of the vehicle body to realize the positioning of the integrated device 100 of the skylight sunshade system and the projection screen with the roof of the vehicle body.

[0048] The integrated device 100 of the canopy shading system and the projection screen may also include a baffle. Each tank chain support 41 has a baffle on its inner side. The baffle is used to cover the internal structure of the tank chain support 41. The baffle can be integrated with the tank chain support 41.

[0049] When the integrated device 100 of the canopy shading system and the projection screen is working, the shading curtain of the canopy shading device 10 can be independently unfolded and rolled up, and the screen of the screen assembly 20 can be independently unfolded and rolled up. The movement of the screen assembly 20 is achieved by the screen assembly moving component 30. Specifically, by controlling the motor 31, the motor 31 drives the output gear to rotate forward or backward, and the two flexible shafts 32 move synchronously along the corresponding flexible shaft guide grooves, and drive the two sliders 33 to move along the corresponding slider guide grooves 1132. The two sliders 33 drive the screen assembly 20 to move synchronously, so as to realize the position adjustment of the screen assembly 20 in the extension direction of the side beam 113, ensuring that the screen assembly 20 moves smoothly and avoids tilting or jamming.

[0050] This application embodiment also provides a vehicle, which includes the above-described integrated device 100 for the awning sunshade system and projection screen. The integrated device 100 for the awning sunshade system and projection screen is connected to the positioning hole on the vehicle roof via a positioning pin 1134, and engages with corresponding fasteners on the vehicle roof via a fastener 50, thereby achieving rapid installation of the integrated device 100 for the awning sunshade system and projection screen onto the vehicle roof.

[0051] In summary, the integrated device and vehicle for the canopy shading system and projection screen provided in this application utilize the canopy frame of the canopy shading device as a carrier. A movable component for the screen assembly is installed on the canopy frame, allowing the screen assembly to move along the canopy frame and meeting the viewing needs of passengers in different seating positions. Integrating the canopy shading system with the screen assembly, and adopting a movable design for the screen assembly, avoids the limitations of fixed installation on vehicle interior space, improving the flexibility of interior space utilization. Using a tank chain to protect and guide the electrical wiring harness connected to the screen assembly effectively solves the problem of the electrical wiring harness easily becoming tangled or twisted during the movement of the screen assembly, reducing the risk of damage to the electrical wiring harness and improving safety.

[0052] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
