[0055] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] An embodiment of this application provides a shielding device 100, which includes a housing 10 and a shielding component 30.

[0057] Specifically, such as Figures 1-8As shown, the housing 10 has a mounting cavity 11 and an opening 12, with the opening 12 communicating with the mounting cavity 11. The shielding component 30 is located inside the mounting cavity 11, and the shielding component 30 can extend or retract from the opening 12. Thus, when the shielding component 30 extends from the opening 12, it can protect the user or equipment from high temperature and ultraviolet radiation, and the shielding component 30 can also block rainwater, meeting the required shielding needs; when the shielding component 30 retracts from the opening 12, the housing 10 can store and protect the shielding component 30, making it easy to carry the shielding device 100.

[0058] In some embodiments of this application, the shading device 100 is a sunshade curtain, capable of blocking sunlight or rain. Of course, in other embodiments, the shading device 100 can also be a privacy shading device.

[0059] In addition, such as Figure 3 , Figures 6-8 As shown, the shielding device 100 also includes a cover assembly 20, which is movably disposed at the opening 12, so that the cover assembly 20 can open or close the opening 12.

[0060] According to the embodiments of this application, when the cover assembly 20 opens the opening 12, the shielding assembly 30 can extend out of the opening 12 to meet the required usage requirements; when the cover assembly 20 closes the opening 12, it can prevent the shielding assembly 30 from being exposed and causing damage, and prevent other structures from entering the mounting cavity 11 through the opening 12 and causing damage to the shielding assembly 30 and other structures, which is beneficial to extending the service life.

[0061] In some embodiments of this application, such as Figure 3 , Figures 6-8 As shown, the cover assembly 20 is rotatably disposed at the opening 12, allowing the cover assembly 20 to open or close the opening 12 by flipping, thus saving arrangement space. In other embodiments of this application, the cover assembly 20 may also be slidably disposed at the opening 12, allowing the cover assembly 20 to open or close the opening 12 by sliding, thereby achieving the same function of opening or closing the opening 12.

[0062] According to the embodiments of this application, the shielding device 100 has a shielding component 30 located in the mounting cavity 11. The cover component 20 moves to open or close the opening 12. When the cover component 20 opens the opening 12, the shielding component 30 can extend or retract from the opening 12, which facilitates the use and protection requirements of the shielding component 30, helps to extend its service life, avoids inconvenience caused by manual operation, and improves the user experience.

[0063] In some embodiments of this application, such as Figure 3 , Figures 6-8 As shown, the covering device 100 also includes a flipping device 40, which is connected to the cover assembly 20 and can drive the cover assembly 20 to rotate. Therefore, when the flipping device 40 drives the cover assembly 20 to open the opening 12, the covering component 30 can easily extend from the opening 12 to meet the required usage needs; when the flipping device 40 drives the cover assembly 20 to close the opening 12, it can prevent the covering component 30 from being exposed and damaged, and prevent other structures from entering the mounting cavity 11 through the opening 12 and damaging the flipping device 40 and other structures, thus extending its service life. At the same time, the flipping device 40 drives the cover assembly 20, avoiding the inconvenience of manual operation and improving the user experience.

[0064] In some embodiments of this application, such as Figure 11 and Figure 12 As shown, the shielding component 30 is disposed on the cover assembly 20, so that the shielding component 30 can rotate simultaneously with the cover assembly 20. When the cover assembly 20 rotates, the shielding component 30 can extend from the mounting cavity 11 to the opening 12, or retract from the opening 12 back into the mounting cavity 11, so that the shielding component 30 can be exposed from the opening 12, thereby facilitating the subsequent extension or retraction of the shielding component 30 from the opening 12, making the operation more convenient.

[0065] According to some embodiments of this application, such as Figure 11 and Figure 12 As shown, the cover assembly 20 includes a baffle plate 21 and an end plate 22, the baffle plate 21 being along the length direction of the opening 12 (e.g., Figure 11 Extending in the front-back direction shown, the shield 21 has end plates 22 connected to both ends in the length direction. The two end plates 22 can improve the structural strength of both ends in the length direction of the cover assembly 20 and avoid deformation and other problems.

[0066] In addition, such as Figure 11 and Figure 12 As shown, the flipping device 40 is connected to at least one of the baffle plate 21 and the end plate 22. That is, the flipping device 40 can be connected to the baffle plate 21, or the flipping device 40 can be connected to the end plate 22, or the flipping device 40 can be connected to both the baffle plate 21 and the end plate 22. This allows the flipping device 40 to drive the baffle plate 21 to open or close the opening 12 through its connection with the baffle plate 21 and / or the end plate 22, thus fulfilling the driving requirement of the flipping device 40 on the baffle plate 21. Furthermore, the connection relationship between the flipping device 40 and the cover assembly 20 is flexible and can be set according to actual conditions to meet different setting requirements.

[0067] It should be noted that, for ease of description, the directions such as "front and back" and "left and right" in this application are based on the orientation relationships shown in the attached drawings, and are not a limitation on the orientation in actual application.

[0068] In some embodiments of this application, such as Figure 7 , Figure 8 and Figure 13 As shown, the flipping device 40 includes a first driving member 41 and a first transmission mechanism 42. The first driving member 41 is disposed on the housing 10, which can fix the first driving member 41. The first transmission mechanism 42 is connected to the first driving member 41, so that the first transmission mechanism 42 can transmit the power of the first driving member 41 to the cover assembly 20, thereby driving the cover assembly 20 to rotate, realizing the rotation requirement of the cover assembly 20, avoiding problems such as inconvenience caused by manual operation, and improving the user experience.

[0069] In the embodiments of this application, the specific structure of the first transmission mechanism 42 can be set according to the actual situation.

[0070] For example, in some embodiments, such as Figures 6-8 As shown, a first mounting plate 13 is provided inside the housing 10, and a first guide hole 131 is provided on the first mounting plate 13. The cover assembly 20 and the first driving member 41 are respectively located in the thickness direction of the first mounting plate 13 (e.g., Figure 6 On both sides of the first mounting plate 13 (in the front-back direction shown), the first transmission mechanism 42 includes a first connecting rod 421, a second connecting rod 422, and a third connecting rod 423. The first connecting rod 421 is located on the side of the first mounting plate 13 closest to the first driving member 41 (e.g., in the front-back direction shown). Figure 6 (As shown in the front side), one end of the first connecting rod 421 is connected to the first driving member 41, and the other end of the first connecting rod 421 is provided with a second guide hole 51. The second connecting rod 422 is movably disposed in the first guide hole 131, and one end of the second connecting rod 422 is provided with a first protrusion 52, which is movably disposed in the second guide hole 51. The third connecting rod 423 is located on the side of the first mounting plate 13 near the cover assembly 20 (e.g., the front side). Figure 6 (As shown in the rear side), one end of the third connecting rod 423 is connected to the cover assembly 20, and the third connecting rod 423 is rotatably connected to the first mounting plate 13. The other end of the third connecting rod 423 is rotatably connected to the end of the second connecting rod 422 away from the first protrusion 52. For example, the first drive member 41 can be a motor.

[0071] Therefore, when the first driving member 41 is working, it can drive the first connecting rod 421 to swing around the connection point between the first driving member 41 and the first connecting rod 421. Through the cooperation of the first protrusion 52 and the second guide hole 51, the first connecting rod 421 can drive the second connecting rod 422 to move within the first guide hole 131, and limit the swing range of the first connecting rod 421, ensuring reliable limiting and avoiding problems such as excessive movement. Through the movement of the second connecting rod 422, the second connecting rod 422 can drive the third connecting rod 423 to rotate around the connection point between the third connecting rod 423 and the first mounting plate 13, for example, by 90°, thereby realizing the flipping requirement of the cover assembly 20 and facilitating the opening or closing of the opening 12 of the cover assembly 20. At the same time, through the linkage movement of the first transmission mechanism 42, it is easy to control the flipping of the cover assembly 20, making the structure of the first transmission mechanism 42 simple, easy to process and manufacture, and conducive to reducing production costs.

[0072] For example, in some embodiments, such as Figure 13 As shown, the cover assembly 20 has a first gear 23 at one end near the opening 12. The first transmission mechanism 42 includes a first rack 424 and an abutment member 425. The housing 10 has a first rack 424 located on the housing 10 opposite to the first gear 23. The first rack 424 can mesh with the first gear 23. The first driving member 41 can drive the rack along the opening direction of the opening 12 (e.g., Figure 5 (As shown in the left and right directions) the abutment 425 abuts against the end of the cover assembly 20 near the opening 12.

[0073] Therefore, when the first driving member 41 is working, the first driving member 41 can drive the first rack 424 to move along the direction of the opening 12, so that the first rack 424 drives the first gear 23 to rotate. Under the limiting action of the abutment member 425, the end of the cover assembly 20 near the opening 12 rotates around the central axis of the first gear 23, so that the cover assembly 20 is raised or lowered. For example, the cover assembly 20 can rotate clockwise or counterclockwise around the central axis of the first gear 23, so that the cover assembly 20 can open or close the opening 12. The structure is simple and easy to process and manufacture.

[0074] The transmission is achieved by meshing the first rack 424 with the first gear 23, which has a large load-bearing capacity, making the flipping process smoother and more stable, effectively reducing vibration and noise, and ensuring the accuracy of lifting and lowering, making the operation more reliable. At the same time, the structure is simple, the manufacturing cost is low, and it is easy to maintain.

[0075] According to some embodiments of this application, such as Figure 11 and Figure 12As shown, the shielding assembly 30 includes a shielding body 31 and an unfolding device 32. The unfolding device 32 is connected to the shielding body 31. The unfolding device 32 can drive the shielding body 31 to extend or retract from the opening 12, so that the shielding body 31 can protect users or equipment from high temperature and ultraviolet radiation and can block rainwater, thus meeting the shielding requirements of the shielding assembly 30. Furthermore, the unfolding device 32 drives the shielding body 31, which avoids the inconvenience caused by manual operation and improves the user experience.

[0076] In some embodiments of this application, such as Figure 11 and Figure 12 As shown, the blocking body 31 includes a blocking member 311, a first rotating shaft 312, and a second rotating shaft 313. The first rotating shaft 312 and the second rotating shaft 313 are respectively aligned with the length direction of the blocking member 311 (e.g., along the length direction of the blocking member 311). Figure 12 The two ends of the shield 311 are connected in the left and right directions shown in the figure, and the shield 311 is wrapped around the first rotating shaft 312 so that the first rotating shaft 312 can store the shield 311 neatly. The first rotating shaft 312 is rotatably disposed in the housing 10, and the unfolding device 32 can drive the second rotating shaft 313 to move in a direction away from or close to the first rotating shaft 312.

[0077] Therefore, when the unfolding device 32 drives the second rotating shaft 313 to move away from the first rotating shaft 312, the rotation of the first rotating shaft 312 facilitates the removal of the shielding member 311 from the first rotating shaft 312, which helps improve usage efficiency and user experience. When the unfolding device 32 drives the second rotating shaft 313 to move closer to the first rotating shaft 312, the rotation of the first rotating shaft 312 facilitates the wrapping member 311 around the first rotating shaft 312, which helps improve storage efficiency and user experience. Furthermore, the shielding body 31 has a simple structure, is easy to process and manufacture, and helps reduce production costs.

[0078] According to some embodiments of this application, such as Figure 11 and Figure 12 As shown, the unfolding device 32 includes a second driving member 321 and a transmission assembly 322. At least one end of the first rotating shaft 312 along its length is provided with the transmission assembly 322. The transmission assembly 322 includes a first transmission rod 61 and a second transmission rod 62. The first transmission rod 61 and the second transmission rod 62 are rotatably connected. The end of the second transmission rod 62 furthest from the first transmission rod 61 (e.g., the end away from the first transmission rod 61) Figure 12 The right end shown is rotatably connected to the second rotating shaft 313, and the second driving member 321 is connected to the end of the first transmission rod 61 away from the second transmission rod 62 (e.g., the right end shown). Figure 12(As shown on the left end) The second driving member 321 can drive the first transmission rod 61 to rotate in a direction away from or towards the first rotating shaft 312, thereby enabling the shielding body 31 to extend or retract from the opening 12, making control simpler and more convenient. Furthermore, the linkage movement of the second driving member 321 facilitates control of the extension and retraction of the shielding body 31, simplifying the structure of the transmission assembly 322, making it easier to manufacture and reducing production costs. For example, the first transmission rod 61 and the second transmission rod 62 are hinged together, and the second transmission rod 62 is hinged together with the second rotating shaft 313. For example, the second driving member 321 can be a motor.

[0079] In some embodiments of this application, such as Figure 12 As shown, the end of the first transmission rod 61 furthest from the second transmission rod 62 is provided with a third guide hole 611. The unfolding device 32 also includes a third transmission rod 63. One end of the third transmission rod 63 is connected to the second driving member 321, and the other end of the third transmission rod 63 is provided with a second protrusion 631. The second protrusion 631 is movably disposed in the third guide hole 611. The second driving member 321 drives the third transmission rod 63 to rotate. Thus, when the second driving member 321 is working, it can drive the third transmission rod 63 to swing around the connection point between the second driving member 321 and the third transmission rod 63. Through the cooperation of the second protrusion 631 and the third guide hole 611, the third transmission rod 63 can drive the first transmission rod 61 to rotate in a direction away from or close to the first rotating shaft 312, thereby fulfilling the driving requirements of the first transmission rod 61, avoiding interference and other problems, and limiting the swing range of the third connecting rod 423 to ensure reliable positioning and avoid excessive movement.

[0080] For example, such as Figure 12 As shown, when the second driving member 321 drives the third transmission rod 63 to rotate counterclockwise, the third transmission rod 63, through the cooperation of the second protrusion 631 and the third guide hole 611, can push the first transmission rod 61 to rotate in a direction away from the first rotating shaft 312, so that the second transmission rod 62, which is rotatably connected to the first transmission rod 61, can rotate relative to the first transmission rod 61. Thus, the second transmission rod 62 can push the second rotating shaft 313 to move in a direction away from the first rotating shaft 312, thereby allowing the blocking member 311 to extend from the opening 12; Figure 11 As shown, when the second driving member 321 drives the third transmission rod 63 to rotate clockwise, the third transmission rod 63, through the cooperation of the second protrusion 631 and the third guide hole 611, can push the first transmission rod 61 to rotate toward the direction close to the first rotating shaft 312, so that the second transmission rod 62, which is rotatably connected to the first transmission rod 61, can rotate relative to the first transmission rod 61. Thus, the second transmission rod 62 can push the second rotating shaft 313 to move toward the direction close to the first rotating shaft 312, so that the blocking member 311 can retract from the opening 12.

[0081] According to some embodiments of this application, such as Figure 11 and Figure 12 As shown, the unfolding device 32 also includes a third driving member 323, which is connected to the first rotating shaft 312. The third driving member 323 can drive the first rotating shaft 312 to rotate around its central axis. By rotating the first rotating shaft 312 around its central axis, the blocking member 311 can be loosened or tightened, making it easier to remove or wrap the blocking member 311 from the first rotating shaft, thereby facilitating the extension or retraction of the blocking member 311 from the opening 12. For example, the third driving member 323 can be a motor.

[0082] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the shielding device 100 also includes a receiving member 70, which has a receiving cavity 71 and an outlet 72. The outlet 72 communicates with the receiving cavity 71. The housing 10 is movably disposed in the receiving cavity 71. The receiving cavity 71 facilitates the placement and storage of the housing 10, meets the required placement needs, and can hide the overall structure of the housing 10 to avoid exposure and damage.

[0083] In addition, such as Figures 3-5 , Figure 9 , Figure 10 , Figure 14 and Figure 15 As shown, the shielding device 100 also includes a lifting device 80, which can drive the housing 10 to protrude from or retract from the outlet 72, making it convenient to store and use the housing 10, avoiding inconvenience caused by manual operation, and improving the user experience.

[0084] In some embodiments of the shielding assembly 30, which includes a shielding body 31 and an unfolding device 32, such as Figures 1-6 As shown, the lifting device 80 can drive the housing 10 to protrude from the outlet 72, the flipping device 40 can drive the cover assembly 20 to rotate to open the opening 12, and the unfolding device 32 can drive the shielding body 31 to extend from the opening 12, thereby fulfilling the shielding requirements of the shielding device 100; the unfolding device 32 can drive the shielding body 31 to retract from the opening 12, the flipping device 40 can drive the cover assembly 20 to rotate to close the opening 12, and the lifting device 80 can drive the housing 10 to retract from the outlet 72, thereby realizing the storage and concealment of the shielding device 100. This achieves the three-stage movement of the shielding device 100, avoiding the inconvenience caused by manual operation and improving the user experience.

[0085] According to some embodiments of this application, such as Figure 9 , Figure 10 , Figure 14 and Figure 15 As shown, the lifting device 80 includes a fourth driving member 81 and a second transmission mechanism 82. The second transmission mechanism 82 is connected to the fourth driving member 81 and the housing 10. The second transmission mechanism 82 can convert the rotation of the fourth driving member 81 into the linear motion of the housing 10, enabling the housing 10 to be exposed or retracted from the outlet 72 along a straight line, ensuring reliable movement of the housing 10, and making the structure of the shielding device 100 compact, which is beneficial to reducing the space occupied.

[0086] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, a gear section 711 is provided within the receiving cavity 71. A portion of the gear section 711 is arc-shaped. The second transmission mechanism 82 includes a first connecting rod 821 and a second connecting rod 822. One end of the first connecting rod 821 is connected to the fourth driving member 81, and the other end of the first connecting rod 821 is provided with a second gear 823, which meshes with the gear section 711. One end of the second connecting rod 822 is rotatably connected to the other end of the first connecting rod 821, and the end of the second connecting rod 822 away from the first connecting rod 821 is connected to the housing 10. For example, the fourth driving member 81 can be a motor.

[0087] Therefore, when the fourth driving member 81 is working, it can drive the first connecting rod 821 to rotate around the connection point between the first connecting rod 821 and the first driving member 41. The rotation of the first connecting rod 821 drives the second connecting rod 822 to move, allowing the second connecting rod 822 to drive the housing 10 to protrude or retract from the outlet 72. This converts the rotation of the fourth driving member 81 into linear motion of the housing 10. Furthermore, the first connecting rod 821 can drive the second gear 823 to mesh with the gear section 711. The meshing of the gears improves precision, making the movement of the blocking device 100 more accurate. Thus, the second transmission mechanism 82 facilitates control of the movement of the housing 10, simplifies its structure, facilitates manufacturing, and helps reduce production costs.

[0088] According to some embodiments of this application, such as Figure 9 and Figure 10As shown, a second mounting plate 712 is provided inside the receiving cavity 71. The fourth driving member 81 and the gear part 711 are connected to the second mounting plate 712, enabling the connection between the fourth driving member 81 and the gear part 711 and ensuring reliable fixation. The fourth driving member 81 and the gear part 711 are located on one side of the second mounting plate 712. The second mounting plate 712 has a hollow part 713, which is at least partially opposite to the gear part 711. The second connecting rod 822 is located on the side of the second mounting plate 712 away from the fourth driving member 81. The second gear 823 can extend into the hollow part 713, so that the second gear 823 meshes with the gear part 711 to meet the required mating requirements, ensuring a compact structure and reducing space occupation.

[0089] Therefore, when the fourth driving member 81 is working, the fourth driving member 81 can drive the first connecting rod 821 to rotate around the connection point of the first connecting rod 821 and the first driving member 41. The rotation of the first connecting rod 821 can drive the second connecting rod 822 to move. When the first connecting rod 821 moves toward the extreme position of the hollow part 713, the second connecting rod 822 can drive the housing 10 to move, so as to expose or retract the housing 10.

[0090] For example, such as Figure 9 and Figure 10 As shown, when the first link 821 rotates clockwise, the first link 821 can drive the second link 822 to move, so that the second link 822 can drive the housing 10 to protrude from the outlet 72; when the first link 821 rotates counterclockwise, the first link 821 can drive the second link 822 to move, so that the second link 822 can drive the housing 10 to retract from the outlet 72.

[0091] In some embodiments, such as Figure 9 and Figure 10 As shown, the gear part 711 is formed in the shape of a ring, the teeth of the gear part 711 are located inside the ring, and the second gear 823 is located radially inside the ring, which facilitates the meshing of the second gear 823 with the teeth. The ring-shaped gear part 711 can limit the movement position of the second gear 823, prevent the gear part 711 from disengaging from the second gear 823, and ensure reliable operation.

[0092] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, the second mounting plate 712 is also provided with a bracket 715, and the fourth driving component 81 is provided on the bracket 715. The bracket 715 can support the fourth driving component 81 and ensure that the fourth driving component 81 is reliably fixed on the second mounting plate 712.

[0093] In some embodiments, such as Figure 9 and Figure 10As shown, the gear part 711 is provided with a fixing part 716, and the fixing part 716 and the second connecting plate are connected by fasteners to ensure that the gear part 711 is reliably fixed on the second connecting plate and facilitates assembly. For example, the fastener can be a bolt.

[0094] In some embodiments, such as Figure 9 and Figure 10 As shown, the fixing part 716 is a plurality of parts spaced apart along the circumferential direction of the gear part 711. The multiple fixing parts 716 can be connected to different positions of the second connecting plate by fasteners to ensure that the fixing part 716 is reliably connected to the second connecting plate and to avoid problems such as the gear part 711 being misaligned, thereby ensuring the precision of the movement of the housing 10.

[0095] In the embodiments of this application, the number of fixing parts 716 can be flexibly set according to actual conditions. For example, the fixing parts 716 can be as follows: Figure 9 The number shown is four, but it can also be two, three, five, six or more, all of which are within the scope of protection of this application.

[0096] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the second mounting plate 712 is provided with a guide groove 714, and the housing 10 is provided with a guide member 14. Thus, when the housing 10 moves, the guide member 14 cooperates with the guide groove 714 to guide the housing 10, prevent the housing 10 from tilting, and ensure the reliability of the movement of the housing 10.

[0097] In some embodiments, such as Figure 9 and Figure 10 As shown, guide members 14 are provided at both ends of the housing 10 along its length. There are two second mounting plates 712, which are located on opposite sides of the housing 10 along its length. The fourth driving member 81 and the gear part 711 are connected to one of the second mounting plates 712 to fix the fourth driving member 81 and the gear part 711. Both second mounting plates 712 are provided with guide grooves 714. The guide members 14 located on the same side cooperate with the guide grooves 714 to ensure reliable and stable movement at both ends of the housing 10, prevent the housing 10 from tilting during movement, and ensure the reliability of the movement of the housing 10.

[0098] According to some embodiments of this application, such as Figure 10As shown, the connection points of the first link 821 and the second gear 823, and the connection points of the first link 821 and the second link 822 are staggered along the circumferential direction of the gear part 711. That is, the connection points of the first link 821 and the second gear 823, the connection points of the first link 821 and the second link 822, and the connection point of the first link 821 and the fourth driving member 81 roughly form a triangle. Therefore, when the first link 821 drives the second link 822 to move, the overlap of the connection points of the first link 821 and the second gear 823, and the connection points of the first link 821 and the second link 822 can be avoided to prevent jamming. This prevents dead point phenomenon and ensures reliable operation of the second transmission mechanism 82.

[0099] In some embodiments of this application, such as Figure 14 As shown, the second transmission mechanism 82 includes a cam 824 and a moving member 825. The fourth driving member 81 is connected to the cam 824, enabling the fourth driving member 81 to drive the cam 824 to rotate. One end of the moving member 825 abuts against the cam 824, and the other end of the moving member 825 is connected to the housing 10. When the fourth driving member 81 drives the cam 824 to rotate, the moving member 825 abuts against the cam 824, which drives the moving member 825 to move along the extension direction of the outlet 72, realizing the conversion of continuous rotational motion into reciprocating linear motion. This allows the moving member 825 to drive the housing 10 to protrude or retract from the outlet 72. The first transmission mechanism 42 has a simple structure, is easy to control and manufacture, and helps to reduce production costs.

[0100] Meanwhile, by designing the external curve of cam 824, various complex motion laws can be realized, such as specific displacement, velocity and acceleration requirements, ensuring the accuracy and reliability of motion, and the structure is simple, compact and easy to process and manufacture.

[0101] In some embodiments, such as Figure 14 As shown, the moving part 825 includes a roller 91 and a frame 92. One end of the frame 92 in the length direction is connected to the housing 10, and the other end of the frame 92 in the length direction is rotatably connected to the roller 91. The roller 91 abuts against the cam 824. By rolling the roller 91 on the cam 824, the friction between the moving part 825 and the cam 824 can be reduced, which is beneficial to extending the service life. Moreover, the moving part 825 has a simple structure and is easy to process and manufacture.

[0102] According to some embodiments of this application, such as Figure 15As shown, the second transmission mechanism 82 includes a third gear 826 and a second rack 827. A fourth driving member 81 is connected to the third gear 826, enabling the fourth driving member 81 to drive the third gear 826 to rotate. The second rack 827 meshes with the third gear 826, and one end of the second rack 827 in the length direction is connected to the housing 10. When the fourth driving member 81 drives the third gear 826 to rotate, the meshing of the second rack 827 with the third gear 826 enables the second rack 827 to move along the extension direction of the outlet 72, thereby causing the second rack 827 to drive the housing 10 to protrude or retract from the outlet 72. The first transmission mechanism 42 has a simple structure, is easy to control and manufacture, and helps to reduce production costs.

[0103] Meanwhile, the transmission is achieved through the meshing of the third gear 826 and the second rack 827, which has a large load-bearing capacity, making the lifting process smoother and more stable, effectively reducing vibration and noise, and ensuring the accuracy of lifting, making the operation more reliable. At the same time, the structure is simple, the manufacturing cost is low, and it is easy to maintain.

[0104] According to some embodiments of this application, such as Figure 1 As shown, the opening 12 is located at least at one of the front, rear, or side portions of the vehicle roof, and the shielding assembly 30 can extend or retract from the opening 12 in a direction parallel to the vehicle roof. By providing the opening 12 at the front of the vehicle roof, the area in front of the vehicle can be shielded; by providing the opening 12 at the front of the rear of the vehicle, the area behind the vehicle can be shielded; by providing the opening 12 at the side of the vehicle roof, the area to the side of the vehicle can be shielded, thereby meeting the shielding needs of various scenarios.

[0105] The vehicle according to the embodiments of this application includes a shielding device 100 and a body assembly 200 according to the embodiments of this application. Since the shielding device 100 according to the embodiments of this application has the aforementioned beneficial technical effects, the vehicle according to the embodiments of this application, with the shielding assembly 30 located within the mounting cavity 11, and the cover assembly 20 moving to open or close the opening 12, allows the shielding assembly 30 to extend or retract from the opening 12 when the cover assembly 20 opens. This facilitates the fulfillment of the shielding assembly 30's usage and protection requirements, extends its service life, avoids inconvenience caused by manual operation, and improves the user experience.

[0106] The shielding device 100 effectively protects the equipment inside the vehicle from high temperatures and ultraviolet rays, and provides sun and rain protection for users, offering a comfortable travel experience for the driver and passengers. Simultaneously, by closing the opening 12 through the cover assembly 20, airflow is prevented from entering the mounting cavity 11 through the opening 12, thus avoiding wind resistance or noise issues and improving the user experience. Furthermore, when the lifting device 80 drives the housing 10 to retract from the outlet 72, the shielding device 100 is concealed, resolving issues such as the shielding device 100 protruding from the body assembly 200 and affecting wind resistance and wind noise, effectively reducing fuel and electricity consumption. It also prevents damage from impacts by other structures to the protruding shielding device 100, ensuring safety.

[0107] In some embodiments of the body assembly 200, including the housing 70 and the lifting device 80, such as Figure 1 and Figure 2 As shown, the body assembly 200 includes a top cover 73, the top cover 73 is provided with a receiving member 70, the receiving member 70 has a receiving cavity 71 and an outlet 72 communicating with the receiving cavity 71. The outlet 72 is located above the top cover 73. The lifting device 80 can drive the housing 10 to protrude or retract from the outlet 72 in the vertical direction, that is, to realize the raising and lowering of the housing 10, thereby realizing the storage and use of the covering device 100. When the housing 10 is raised and protruded from the outlet 72, the housing 10 can be used as a roof rack for the vehicle, which can meet different usage needs.
