Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a shielding device, a curtain assembly, and a vehicle. Background Technology

[0002] The vehicle is equipped with a projection screen. When the screen is unfolded, a significant gap exists between it and the vehicle's body mounting components, allowing light from the front of the vehicle to pass through and negatively impacting the viewing experience for rear passengers. In related technologies, a light-shielding structure is installed on the body mounting components. When unfolded, this structure covers the gap between the projection screen and the mounting components, blocking light from the front of the vehicle. However, when the projection screen and light-shielding structure are closed, a large gap can easily remain between the light-shielding structure and the walls of the mounting holes on the body mounting components, allowing foreign objects to easily pass through and enter between the body mounting components and the vehicle body. Summary of the Invention

[0003] This application provides a shading device, a curtain assembly, and a vehicle to solve the problem that external foreign objects can easily pass through the gap between the shading structure and the wall of the mounting hole on the vehicle body mounting component.

[0004] In a first aspect, this application provides a light-shielding device, comprising a fixing structure, a light-shielding structure, and a light-shielding structure. The fixing structure is used to connect to a vehicle body mounting component. The vehicle body mounting component has mounting holes. The light-shielding structure is connected to the fixing structure. The light-shielding structure passes through the mounting holes. The light-shielding structure includes a first end and a second end disposed opposite to each other. The first end is rotatably connected to the fixing structure. When the light-shielding structure is in a retracted state relative to the fixing structure, a clearance gap is formed between the second end and the vehicle body mounting component, and the light-shielding structure moves relative to the fixing structure to cover the clearance gap.

[0005] In some embodiments, when the light-shielding structure rotates from the unfolded state to the retracted state relative to the fixed structure, the light-shielding structure drives the blocking structure to move relative to the fixed structure.

[0006] In some embodiments, the blocking structure includes a transmission mechanism and a blocking member. The transmission mechanism is mounted on the fixed structure and connected to the blocking member. When the light-blocking structure rotates from the unfolded state to the retracted state relative to the fixed structure, the light-blocking structure abuts against the transmission mechanism. The transmission mechanism drives the blocking member to move relative to the fixed structure to cover the clearance gap.

[0007] In some embodiments, the transmission mechanism includes a first transmission member and a second transmission member. The first transmission member is connected to the fixed structure, the second transmission member is connected to the first transmission member, the second transmission member is connected to the shielding member, and the shielding member is connected to the fixed structure. When the light-shielding structure rotates relative to the fixed structure from the unfolded state to the retracted state, the light-shielding structure abuts against the side of the first transmission member facing the light-shielding structure. The first transmission member drives the second transmission member to move relative to the fixed structure, and the second transmission member drives the shielding member to move relative to the fixed structure to cover the clearance gap.

[0008] In some embodiments, the blocking device further includes an elastic element connected between the fixed structure and the blocking structure.

[0009] In some embodiments, the blocking device further includes an elastic element connected between the first transmission member and the fixed structure. When the light-blocking structure rotates relative to the fixed structure from the contracted state to the unfolded state, the elastic force of the elastic element is used to move the first transmission member closer to the light-blocking structure; and / or, the elastic element is connected between the second transmission member and the fixed structure. When the light-blocking structure rotates relative to the fixed structure from the contracted state to the unfolded state, the elastic force of the elastic element is used to move the second transmission member away from the blocking member away from the clearance gap; and / or, the elastic element is connected between the blocking member and the fixed structure. When the light-blocking structure rotates relative to the fixed structure from the contracted state to the unfolded state, the elastic force of the elastic element is used to move the blocking member away from the clearance gap.

[0010] In some embodiments, the blocking device further includes an elastic element connected between the first transmission element and the second transmission element. When the light-blocking structure rotates relative to the fixed structure from the contracted state to the unfolded state, the elastic force of the elastic element is used to move the first transmission element closer to the light-blocking structure. And / or, when the light-blocking structure rotates relative to the fixed structure from the contracted state to the unfolded state, the elastic force of the elastic element is used to move the blocking element away from the clearance gap.

[0011] In some embodiments, the fixing structure includes a body portion and a fixing seat. The body portion is used to connect with the vehicle body mounting component. The light-shielding structure is rotatably connected to the body portion. The fixing seat is fixed to the body portion. The first transmission member is rotatably connected to the fixing seat. The fixing seat is provided with a baffle. The baffle is located on the side of the first transmission member away from the light-shielding structure.

[0012] In some embodiments, the shielding structure is provided with an abutment groove, and when the light-shielding structure abuts against the shielding structure, a portion of the light-shielding structure is accommodated within the abutment groove.

[0013] In some embodiments, the shielding structure includes a connecting portion and an abutting portion. The connecting portion is connected to the fixed structure, and the abutting portion is connected to the end of the connecting portion. An abutting groove is formed between the abutting portion and the connecting portion. When the light-shielding structure is in the retracted state relative to the fixed structure, the abutting portion abuts against the side of the light-shielding structure away from the clearance gap.

[0014] In some embodiments, the shape of the shielding member near the light-shielding structure is adapted to the shape of the second end on the side away from the first end.

[0015] In some embodiments, the light-shielding structure includes a main body and a roller. The main body includes a first end and a second end, and the roller is rotatably connected to the second end. The roller is used to abut against the light-shielding structure.

[0016] In some embodiments, the light-shielding structure further includes a top abutment fixed to the side of the second end away from the first end, or the top abutment fixed to the side of the main body portion near the shielding structure in the rotation direction of the fixed structure, and the roller is rotatably connected to the end of the top abutment near the shielding structure.

[0017] In some embodiments, when the shielding structure covers the clearance gap, the distance between the shielding structure and the light-shielding structure is less than or equal to 3 mm, and the distance between the shielding structure and the vehicle body mounting component is less than or equal to 3 mm.

[0018] Secondly, this application provides a screen assembly, which includes a screen and a shielding device as described above, wherein the screen is connected to the shielding device.

[0019] Thirdly, this application provides a vehicle including a body and a curtain assembly as described above, the curtain assembly being connected to the body.

[0020] The shielding device, curtain assembly, and vehicle provided in this application, based on the setting of the shielding structure, when the light-shielding structure is in a retracted state relative to the fixed structure, the shielding structure moves relative to the fixed structure to cover the clearance gap, thereby blocking external foreign objects through the shielding structure, reducing the risk of foreign objects passing through the clearance gap, and preventing users from observing other components between the vehicle body mounting component and the vehicle body through the clearance gap from the side of the vehicle body mounting component. By shielding the light-shielding structure, the visual size of the gap between the second end of the light-shielding structure and the hole wall of the mounting hole is reduced, improving the overall aesthetics of the vehicle body mounting component and enhancing the visual aesthetics of the vehicle interior.

[0028] Please see Figure 1 , Figure 1 This is a cross-sectional view of a vehicle 1000 provided in an embodiment of this application. This application provides a vehicle 1000, which includes a body 100 and a screen assembly 300. The screen assembly 300 is connected to the body 100. The screen assembly 300 is used in conjunction with a projection device to display images, videos, etc., to enrich the entertainment functions of the vehicle 1000. The vehicle 1000 includes, but is not limited to, pure electric vehicles, hybrid electric vehicles, range-extended electric vehicles, and plug-in hybrid electric vehicles.

[0029] The screen assembly 300 includes a screen 310 and a blocking device 320. The screen 310 is connected to the blocking device 320. The blocking device 320 is mounted on the side of the vehicle body 100 and is used to block the gap between the screen 310 and the vehicle body mounting member 200 to provide light blocking, reduce the light shining from the front row of the vehicle 1000 through the gap between the screen 310 and the vehicle body mounting member 200 to the rear row, improve the viewing experience of rear passengers, and improve the isolation between the front and rear rows, enhancing the privacy of both front and rear passengers. Two blocking devices 320 can be provided, with the screen 310 located between the two blocking devices 320. The vehicle body mounting member 200 can be configured as a B-pillar trim panel, a C-pillar trim panel, or other structures within the vehicle body 100.

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of the structure of the shielding device 320 and the vehicle body mounting component 200 when the device is in the deployed state, as provided in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of the shielding device 320 in the retracted state and the vehicle body mounting component 200 provided in this application embodiment. Figure 4 yes Figure 3 Enlarged view at point I. The vehicle body mounting component 200 has a mounting hole 201. A shielding device 320 passes through the mounting hole 201. The shielding device 320 has an extended state and a retracted state. When the shielding device 320 is in the extended state, it extends relative to the vehicle body mounting component 200 towards the curtain 310 to cover the gap between the curtain 310 and the vehicle body mounting component 200. When the shielding device 320 is in the retracted state, it retracts relative to the vehicle body mounting component 200 away from the curtain 310. However, when the shielding device 320 is in the retracted state, the gap between the bottom of the shielding device 320 and the wall of the mounting hole 201 increases, making it easier for foreign objects to enter between the vehicle body mounting component 200 and the vehicle body 100, and reducing the overall aesthetics of the vehicle body mounting component 200.

[0031] Please refer to the following: Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 This is a cross-sectional view of the shielding device 320 provided in the embodiment of this application when it is in the deployed state. Figure 6 for Figure 5 Enlarged view at point II, Figure 7 This is a cross-sectional view of the shielding device 320 provided in the embodiment of this application when it is in the retracted state. Figure 8 for Figure 7 Enlarged view of section III.

[0032] In this embodiment, the shading device 320 includes a fixing structure 10, a shading structure 20, and a light-blocking structure 30. The fixing structure 10 is used to connect to the vehicle body mounting component 200. The shading structure 20 is connected to the fixing structure 10. The light-blocking structure 30 passes through the mounting hole 201. The light-blocking structure 30 includes a first end 301 and a second end 302 disposed opposite to each other. The first end 301 is rotatably connected to the fixing structure 10. The light-blocking structure 30 has an unfolded state and a retracted state relative to the fixing structure 10. When the light-blocking structure 30 is in the unfolded state relative to the fixing structure 10, the light-blocking structure 30 extends along the mounting hole 201 toward the direction close to the curtain 310 to block the gap between the curtain 310 and the vehicle body mounting component 200. When the light-blocking structure 30 is in the retracted state relative to the fixing structure 10, the light-blocking structure 30 retracts along the mounting hole 201 toward the direction away from the curtain 310. When the light-shielding structure 30 is in a retracted state relative to the fixed structure 10, a clearance gap 202 is formed between the second end 302 and the vehicle body mounting part 200, and the light-shielding structure 20 moves relative to the fixed structure 10 to cover the clearance gap 202.

[0033] In this embodiment, the shielding device 320 is based on the shielding structure 20. When the light-shielding structure 30 is in a retracted state relative to the fixed structure 10, the shielding structure 20 moves relative to the fixed structure 10 to cover the clearance gap 202. This blocks external foreign objects from entering through the shielding structure 20, reducing the risk of foreign objects passing through the clearance gap 202. It also prevents users from observing other components between the vehicle body mounting component 200 and the vehicle body 100 from the side of the vehicle body mounting component 200 through the clearance gap 202. The shielding structure 20 reduces the perceived size of the gap between the second end 302 of the light-shielding structure 30 and the hole wall of the mounting hole 201, improving the overall aesthetics of the vehicle body mounting component 200 and enhancing the visual aesthetics of the interior of the vehicle 1000.

[0034] The shielding structure 20 is movable relative to the fixed structure 10. The shielding structure 20 has an avoidance state relative to the fixed structure 10 (e.g., ...). Figure 6 ) and occlusion states (such as Figure 8 When the blocking structure 20 is in the avoidance state, it moves relative to the fixed structure 10 to a position away from the mounting hole 201 to avoid structural interference between the light-shielding structure 30 and the blocking structure 20 during the deployment process. When the blocking structure 20 is in the blocking state, it moves relative to the fixed structure 10 to a position close to the mounting hole 201 and is positioned opposite to the mounting hole 201 to cover the avoidance gap 202.

[0035] For example, when the light-shielding structure 30 rotates from an unfolded state to a retracted state relative to the fixed structure 10, the light-shielding structure 30 drives the blocking structure 20 to move relative to the fixed structure 10. Thus, the movement of the light-shielding structure 30 causes the blocking structure 20 to move along with it relative to the fixed structure 10, avoiding the need for a separate driving element for the blocking structure 20, simplifying the structure of the blocking device 320, and reducing its cost. Of course, in some embodiments, the blocking device 320 may also be provided with a driving element for driving the blocking structure 20 to move relative to the fixed structure 10.

[0036] Please refer to the following: Figure 6 and Figure 8 The light-blocking structure 20 includes a transmission mechanism 21 and a blocking member 22. The transmission mechanism 21 is mounted on the fixed structure 10 and connected to the blocking member 22. When the light-blocking structure 30 rotates from an unfolded state to a retracted state relative to the fixed structure 10, the light-blocking structure 30 abuts against the transmission mechanism 21, and the transmission mechanism 21 drives the blocking member 22 to move relative to the fixed structure 10 to cover the clearance gap 202. The transmission mechanism 21 is used to transmit the movement of the light-blocking structure 30, adjust the direction of force transmission of the light-blocking structure 30, and thus transmit the force of the light-blocking structure 30 to the blocking member 22 through the transmission mechanism 21, so that the blocking member 22 moves relative to the fixed structure 10, and facilitates the structural layout of each component and reduces structural interference.

[0037] During the process of rotating the light-shielding structure 30 from the unfolded state to the retracted state, the light-shielding structure 30 moves along the side of the vehicle body mounting part 200 toward the fixed structure 10. Figure 6 The shield 22 moves from the avoidance state to the shielding state, and moves along the direction from the fixed structure 10 toward the vehicle body mounting part 200. Figure 6 (From center to right) When the light-shielding structure 30 rotates from the unfolded state to the retracted state, the force of the light-shielding structure 30 is converted to the opposite direction through the transmission mechanism 21, thereby realizing the movement of the blocking member 22 and the light-shielding structure 30 in opposite directions, so that the light-shielding structure 30 drives the blocking member 22 to move to the blocking state through the transmission mechanism 21.

[0038] In some embodiments, the transmission mechanism 21 includes a first transmission member 211 and a second transmission member 212. The first transmission member 211 is connected to the fixed structure 10. The second transmission member 212 is connected to the first transmission member 211. The second transmission member 212 is connected to the blocking member 22. The blocking member 22 is connected to the fixed structure 10. When the light-blocking structure 30 rotates from an unfolded state to a retracted state relative to the fixed structure 10, the light-blocking structure 30 abuts against the side of the first transmission member 211 facing the light-blocking structure 30. The first transmission member 211 drives the second transmission member 212 to move relative to the fixed structure 10, and the second transmission member 212 drives the blocking member 22 to move relative to the fixed structure 10 to cover the clearance gap 202. Thus, through the transmission action of the first transmission member 211 and the second transmission member 212, the light-blocking structure 30 drives the blocking member 22 to move relative to the fixed structure 10, allowing the blocking member 22 to smoothly move from the clearance state to the blocking state. The contact position between the light-shielding structure 30 and the first transmission member 211 can be located at the end of the first transmission member 211 away from the second transmission member 212, or the contact position between the light-shielding structure 30 and the first transmission member 211 can also be located between the two opposite ends of the first transmission member 211.

[0039] Exemplarily, the first transmission member 211 is rotatably connected to the fixed structure 10. The rotatable connection between the first transmission member 211 and the fixed structure 10 is located between the two opposite ends of the first transmission member 211. The contact position between the light-shielding structure 30 and the first transmission member 211 is located on the side away from the second transmission member 212 at the rotatable connection between the first transmission member 211 and the fixed structure 10. When the light-shielding structure 30 contacts the end of the first transmission member 211 away from the second transmission member 212, the first transmission member 211 rotates relative to the fixed structure 10, and the first transmission member 211 drives the second transmission member 212 to move relative to the fixed structure 10.

[0040] The fixing structure 10 may include a body portion 11 and a fixing seat 12. A light-shielding structure 30 is rotatably connected to the body portion 11. The body portion 11 is used for connection and assembly with the vehicle body mounting component 200. The fixing seat 12 is fixed to the body portion 11. A first transmission member 211 is rotatably connected to the fixing seat 12. The fixing seat 12 is provided with a baffle 121, located on the side of the first transmission member 211 away from the light-shielding structure 30. The baffle 121 limits the rotation angle of the first transmission member 211 relative to the fixing seat 12, making the rotation angle of the first transmission member 211 controllable. A buffer pad 122 is provided on the side of the baffle 121 facing the first transmission member 211. The buffer pad 122 buffers the first transmission member 211, reducing noise generated when the first transmission member 211 collides with the fixing seat 12.

[0041] Please see Figure 9 , Figure 9This is a schematic diagram of a portion of the structure of the shielding device 320 provided in some embodiments of this application. In some embodiments, the first transmission member 211 and the fixed structure 10 are slidably connected. The fixed structure 10 is provided with a first guide portion, and the first transmission member 211 is slidably connected to the first guide portion. When the light-shielding structure 30 abuts against the first transmission member 211, it drives the first transmission member 211 to slide along the first guide portion. The first guide portion can be configured as a slide rail or a slide groove.

[0042] Please refer to the following: Figure 6 and Figure 8 For example, the first transmission member 211 and the second transmission member 212 can be rotatably connected. When the light-shielding structure 30 abuts against the first transmission member 211, the first transmission member 211 drives the second transmission member 212 to move relative to the fixed structure 10, and the second transmission member 212 rotates relative to the first transmission member 211.

[0043] Please see Figure 10 , Figure 10 This is a schematic diagram of a portion of the structure of the shielding device 320 provided in other embodiments of this application. In some embodiments, the first transmission member 211 and the second transmission member 212 are slidably connected. One of the first transmission member 211 and the second transmission member 212 may be provided with a groove, and the other of the first transmission member 211 and the second transmission member 212 is provided with a slider that slidably engages with the groove. When the light-shielding structure 30 abuts against the first transmission member 211, the first transmission member 211 moves relative to the fixed structure 10, causing the slider to move along the groove. The force between the sidewall of the slider and the sidewall of the groove drives the second transmission member 212 to move relative to the fixed structure 10. The second transmission member 212 is slidably connected to the fixed structure 10. The fixed structure 10 is provided with a second guide portion, and the second transmission member 212 is slidably connected to the second guide portion. The second guide portion may be configured as a slide rail or a groove.

[0044] Please refer to the following: Figure 6 and Figure 8 For example, the second transmission member 212 and the blocking member 22 are rotatably connected. The blocking member 22 is rotatably connected to the fixed structure 10. When the light-blocking structure 30 abuts against the first transmission member 211, the first transmission member 211 rotates relative to the fixed structure 10. The first transmission member 211 drives the second transmission member 212 to move relative to the fixed structure 10, and the second transmission member 212 drives the blocking member 22 to rotate relative to the fixed structure 10, so that the blocking member 22 moves toward the clearance gap 202. In some embodiments, the second transmission member 212 and the blocking member 22 may also be fixedly connected or slidably connected. In some embodiments, the blocking member 22 and the fixed structure 10 may also be slidably connected.

[0045] Please see Figure 6 , Figure 8 and Figure 11 , Figure 11 This is a partial structural schematic diagram of the shielding device 320 provided in an embodiment of this application. In some embodiments, the shielding structure 20 further includes an elastic member 23. The elastic member 23 is connected between the fixed structure 10 and the shielding structure 20. When the light-shielding structure 30 rotates from a retracted state to an extended state relative to the fixed structure 10, the elastic force of the elastic member 23 is used to move the shielding structure 20 away from the clearance gap 202, so that the shielding structure 20 moves away from the position opposite to the clearance gap 202, thereby avoiding interference between the shielding structure 20 and the light-shielding structure 30, and allowing the light-shielding structure 30 to extend smoothly from the mounting hole 201. The elastic member 23 can be configured as, but is not limited to, a torsion spring, a coil spring, a sheet spring, an elastomer, etc. The elastic force provided by the elastic member 23 is used to give the shielding structure 20 a tendency to move from the shielding state to the clearance state. When the light-shielding structure 30 rotates from the extended state to the retracted state, it comes into contact with the blocking structure 20. The force exerted by the light-shielding structure 30 on the blocking structure 20 causes the elastic element 23 to deform (the elastic element 23 is subjected to tension, compression, or torsion, etc.), thereby allowing the blocking structure 20 to overcome the elastic force of the elastic element 23 and achieve coverage of the clearance gap 202. When the light-shielding structure 30 rotates from the retracted state to the extended state, it separates from the blocking structure 20. Under the action of the elastic force of the elastic element 23, the blocking structure 20 moves in the direction away from the clearance gap 202, achieving automatic reset of the blocking structure 20 to the clearance state.

[0046] In this embodiment, at least one of the first transmission member 211, the second transmission member 212, and the blocking member 22 is connected to at least one elastic member 23. In some embodiments, the elastic member 23 may be a single member, which may be connected to any one of the first transmission member 211, the second transmission member 212, and the blocking member 22. In some embodiments, the elastic member 23 may also be a plurality of members, which may be connected to one or more of the first transmission member 211, the second transmission member 212, and the blocking member 22.

[0047] The elastic element 23 can be connected between the first transmission element 211 and the fixed structure 10, and / or, the elastic element 23 can be connected between the second transmission element 212 and the fixed structure 10, and / or, the elastic element 23 can be connected between the shielding element 22 and the fixed structure 10.

[0048] For example, the elastic element 23 can be connected between the first transmission element 211 and the fixed structure 10. When the light-shielding structure 30 rotates from a retracted state to an extended state relative to the fixed structure 10, the elastic force provided by the elastic element 23 is used to bring the first transmission element 211 closer to the light-shielding structure 30, so that the first transmission element 211 tends to drive the blocking element 22 away from the clearance gap 202 via the second transmission element 212. When the light-shielding structure 30 separates from the first transmission element 211, the first transmission element 211, under the action of the elastic force of the elastic element 23, drives the blocking element 22 to move to the clearance state via the second transmission element 212. The elastic element 23 can be configured as a torsion spring, which is disposed between the fixed base 12 and the first transmission element 211.

[0049] In some embodiments, the elastic member 23 may be connected between the second transmission member 212 and the fixed structure 10. When the light-shielding structure 30 rotates from a retracted state to an expanded state relative to the fixed structure 10, the elastic force provided by the elastic member 23 is used to drive the second transmission member 212 to move the shielding member 22 away from the clearance gap 202.

[0050] In some embodiments, the elastic member 23 may be connected between the shielding member 22 and the fixed structure 10. When the light-shielding structure 30 rotates from a contracted state to an expanded state relative to the fixed structure 10, the elastic force provided by the elastic member 23 is used to move the shielding member 22 away from the clearance gap 202.

[0051] In some embodiments, the elastic element 23 may be provided in multiple ways, and the elastic element 23 may be connected between the first transmission element 211 and the fixed structure 10, between the second transmission element 212 and the fixed structure 10, and between the shielding element 22 and the fixed structure 10.

[0052] In some embodiments, the elastic member 23 may be connected between the first transmission member 211 and the second transmission member 212. When the light-shielding structure 30 rotates from a retracted state to an unfolded state relative to the fixed structure 10, the elastic force of the elastic member 23 is used to move the first transmission member 211 closer to the light-shielding structure 30. And / or, the elastic member 23 may be connected between the second transmission member 212 and the blocking member 22. When the light-shielding structure 30 rotates from a retracted state to an unfolded state relative to the fixed structure 10, the elastic force of the elastic member 23 is used to move the blocking member 22 away from the clearance gap 202.

[0053] In some embodiments, the elastic element 23 can be connected between the first transmission element 211 and the second transmission element 212. When the light-shielding structure 30 rotates from a retracted state to an unfolded state relative to the fixed structure 10, the elastic force of the elastic element 23 is used to bring the first transmission element 211 closer to the light-shielding structure 30. When the light-shielding structure 30 separates from the first transmission element 211, the first transmission element 211, under the action of the elastic force of the elastic element 23, drives the blocking element 22 to move to an avoidance state via the second transmission element 212. In some embodiments, the elastic element 23 can be connected between the second transmission element 212 and the blocking element 22. When the light-shielding structure 30 rotates from a retracted state to an unfolded state relative to the fixed structure 10, the elastic force of the elastic element 23 is used to move the blocking element 22 away from the avoidance gap 202. In some embodiments, multiple elastic elements 23 can be provided, with elastic elements 23 respectively connected between the first transmission element 211 and the second transmission element 212, and between the second transmission element 212 and the blocking element 22.

[0054] Please refer to the following: Figure 6 and Figure 8 In some embodiments, the blocking structure 20 is provided with an abutment groove 2113. When the light-shielding structure 30 abuts against the blocking structure 20, a portion of the light-shielding structure 30 is accommodated within the abutment groove 2113, thereby improving the stability of the light-shielding structure 30 after abutting against the blocking structure 20 and reducing the risk of slippage between the light-shielding structure 30 and the blocking structure 20. The abutment groove 2113 may be located at the end of the first transmission member 211 away from the second transmission member 212, and on the side of the first transmission member 211 facing the light-shielding structure 30.

[0055] The light-shielding structure 20 includes a connecting portion 2111 and an abutting portion 2112. The connecting portion 2111 is connected to the fixing seat 12 of the fixing structure 10. The abutting portion 2112 is connected to the end of the connecting portion 2111. The end of the connecting portion 2111 away from the abutting portion 2112 is connected to the second transmission member 212. An abutting groove 2113 is formed between the abutting portion 2112 and the connecting portion 2111. When the light-shielding structure 30 is in a retracted state relative to the fixing structure 10, the abutting portion 2112 abuts against the side of the light-shielding structure 30 away from the clearance gap 202, thereby reducing the angle between the force exerted by the light-shielding structure 30 on the abutting portion 2112 and the surface of the abutting portion 2112 facing the light-shielding structure 30, improving the stability when the abutting portion 2112 abuts against the light-shielding structure 30, and reducing the risk of slippage between the light-shielding structure 30 and the abutting portion 2112. The connection between the abutting part 2112 and the connecting part 2111 can be provided with an arc transition to reduce frictional loss between the light-shielding structure 30 and the groove wall of the abutting groove 2113.

[0056] In some embodiments, the light-shielding structure 30 includes a main body 31 and a roller 314. The main body 31 includes a first end 301 and a second end 302. The roller 314 is rotatably connected to the end of the main body 31 near the light-shielding structure 20. The roller 314 is rotatably connected to the second end 302. The roller 314 is used to abut against the light-shielding structure 20, so that rolling friction is formed when the main body 31 abuts against the light-shielding structure 20, reducing wear between the main body 31 and the light-shielding structure 20 and extending service life. The roller 314 is used to abut against the first transmission member 211. Of course, in some embodiments, the light-shielding structure 30 may not have the roller 314, and sliding friction is formed when the main body 31 abuts against the light-shielding structure 20.

[0057] Please see Figure 11 In some embodiments, the shape of the shielding member 22 near the light-shielding structure 30 is adapted to the shape of the second end 302 of the light-shielding structure 30 away from the first end 301. This reduces the maximum width of the gap formed between the shielding member 22 and the light-shielding structure 30 when the shielding member 22 covers the clearance gap 202, making the gap size consistent or similar at various locations. This improves the shielding effect of the shielding member 22 on the clearance gap 202, enhances the shielding ability of the shielding member 22 to block foreign objects, and improves the overall aesthetics of the vehicle body mounting component 200. For example, the shape of the end of the second end 302 away from the first end 301 can be an arc-shaped protrusion, and the shape of the shielding member 22 near the light-shielding structure 30 is correspondingly adapted to an arc-shaped groove corresponding to the arc protrusion. In some embodiments, the end of the second end 302 away from the first end 301 can also be planar, and the shape of the shielding member 22 near the light-shielding structure 30 is correspondingly adapted to be planar.

[0058] Please refer to the following: Figure 1 and Figure 8 When the shielding structure 20 covers the clearance gap 202, the distance between the shielding member 22 of the shielding structure 20 and the second end 302 of the light-shielding structure 30 is a first distance D1, which is less than or equal to 3mm. This reduces the size of the gap between the shielding member 22 and the light-shielding structure 30, reduces the risk of foreign objects passing through the gap, and reduces the visual size of the gap between the shielding member 22 and the light-shielding structure 30, thereby improving the overall aesthetics of the vehicle body mounting part 200.

[0059] In some embodiments, when the shielding structure 20 covers the clearance gap 202, the shielding structure 20 is located inside the vehicle body mounting component 200, that is, on the side of the vehicle body mounting component 200 away from the curtain 310. This reduces the processing and assembly difficulty of the shielding structure 20 and the vehicle body mounting component 200, and reduces the risk of interference between the shielding structure 20 and the vehicle body mounting component 200 when the shielding structure 20 moves relative to the fixed structure 10. When the shielding structure 20 covers the clearance gap 202, the distance between the shielding member 22 of the shielding structure 20 and the vehicle body mounting component 200 is a second distance D2, which is less than or equal to 3mm. This reduces the size of the gap between the shielding member 22 and the vehicle body mounting component 200, reduces the risk of foreign objects passing through the gap, and reduces the perceived size of the gap between the shielding member 22 and the vehicle body mounting component 200, improving the overall aesthetics of the vehicle body mounting component 200. In some embodiments, when the shielding structure 20 covers the clearance gap 202, the shielding member 22 of the shielding structure 20 can extend into the mounting hole 201. The shielding member 22 is located between the second end 302 of the light-shielding structure 30 and the hole wall of the mounting hole 201, so as to improve the shielding effect of the shielding member 22 on the clearance gap 202.

[0060] Please refer to the following: Figure 1 and Figure 12 , Figure 12 This is a schematic diagram of the structure of the shading device 320 provided in this application embodiment. The main body 31 may include at least one sub-shading member. Exemplarily, two sub-shading members may be provided. The main body 31 may include a first sub-shading member 311 and a second sub-shading member 312. The first sub-shading member 311 and the second sub-shading member 312 are respectively rotatably connected to the fixed structure 10. In the unfolded state, the first sub-shading member 311 rotates to extend out of the mounting hole 201, and the second sub-shading member 312 rotates to the side of the first sub-shading member 311 away from the vehicle body mounting member 200, so as to increase the shading area of ​​the shading structure 30 by using the first sub-shading member 311 and the second sub-shading member 312, thereby improving the shading effect on the gap between the vehicle body mounting member 200 and the curtain 310. In the retracted state, the first sub-shading member 311 and the second sub-shading member 312 rotate along the vehicle body mounting member 200 away from the curtain 310. The first sub-shading member 311 and the second sub-shading member 312 are arranged in an overlapping manner to reduce the space occupied by the retracted shading structure 30, so as to facilitate the shading structure 30 to be housed between the vehicle body mounting member 200 and the vehicle body 100.

[0061] Please see Figure 8In some embodiments, the light-shielding structure 30 may include a top abutment 313. In some embodiments, the top abutment 313 may be fixed to the side of the second end 302 of the main body 31 away from the first end 301 of the main body 31, which is beneficial to reducing the overall size of the light-shielding structure 30 in the rotational direction of the main body 31 around the fixing structure 10, and to facilitating the housing of the light-shielding structure 30 inside the vehicle body mounting member 200. The top abutment 313 may be fixed to the side of the first sub-light-shielding member 311 away from the rotatable connection with the fixing structure 10.

[0062] In some embodiments, the abutment top 313 is fixed to the side of the main body 31 near the shielding structure 20 in the rotation direction of the fixing structure 10. This helps to reduce the overall size of the light-shielding structure 30 along the line connecting the first end 301 and the second end 302, and also helps to reduce the rotation radius of the light-shielding structure 30, thus reducing the risk of jamming when the light-shielding structure 30 rotates. Specifically, the abutment top 313 can be fixed to the side of the first sub-light-shielding member 311 near the shielding structure 20 in the rotation direction of the fixing structure 10. When the light-shielding structure 30 is in the unfolded state, the abutment top 313 is located on the side of the first sub-light-shielding member 311 away from the second sub-light-shielding member 312.

[0063] The roller 314 is rotatably connected to the end of the abutment 313 near the shielding structure 20. The abutment 313 may protrude relative to the main body 31, and the roller 314 is rotatably connected to the end of the abutment 313 protruding from the main body 31 to prevent interference between the main body 31 and the shielding structure 20 when the roller 314 abuts against the shielding structure 20. The abutment 313 is fixed to the first sub-shield 311 and protrudes relative to the first sub-shield 311 towards the side near the shielding structure 20. The roller 314 is rotatably connected to the end of the abutment 313 away from the first sub-shield 311. In some embodiments, the abutment 313 and the roller 314 may also be connected to a second sub-shield 312 or other sub-shields. The specific position of the abutment 313 on the sub-shield can be specifically set according to actual needs and is not specifically limited in this application.

[0064] Please refer to the following: Figure 1 , Figure 6 , Figure 8 and Figure 12 In some embodiments, the light-shielding structure 30 further includes a follower 315. The follower 315 is rotatably connected to the fixed structure 10. The first sub-light-shielding member 311 is provided with a first guide portion 3111, and the follower 315 is guided and engaged with the first guide portion 3111. The first guide portion 3111 can be configured as a guide groove, and the follower 315 is provided with a pin, which is disposed in the guide groove. In some embodiments, the first guide portion 3111 can also be configured as a guide rail.

[0065] The follower 315 is provided with a second guide portion 3151. The second sub-shielding member 312 is guided and engaged with the second guide portion 3151 and can slide along the second guide portion 3151. The second guide portion 3151 can be configured as a guide groove, and the second sub-shielding member 312 is provided with a pin, which is disposed in the guide groove. In some embodiments, the second guide portion 3151 can also be configured as a guide rail.

[0066] The blocking device 320 also includes a driving member 40. The second sub-shading member 312 is provided with a third guide portion 3121. The driving member 40 is guided and engaged with the third guide portion 3121 and can slide along the third guide portion 3121. The third guide portion 3121 can be configured as a guide groove, and the first sub-shading member 311 is provided with a pin, which is disposed in the guide groove. In some embodiments, the third guide portion 3121 can also be configured as a guide rail.

[0067] A fourth guide portion 111 is provided on the fixed structure 10. The driving member 40 is guided and engaged with the fourth guide portion 111 and can slide along the fourth guide portion 111. When the driving member 40 slides along the fourth guide portion 111, it simultaneously slides along the third guide portion 3121 and drives the second sub-light-shielding member 312 to rotate relative to the fixed structure 10 through the third guide portion 3121. When the second sub-light-shielding member 312 rotates, it slides along the second guide portion 3151 and drives the follower 315 to rotate relative to the fixed structure 10 through the second guide portion 3151. When the follower 315 rotates, it slides along the first guide portion 3111 and drives the first sub-light-shielding member 311 to rotate relative to the fixed structure 10 through the first guide portion 3111. This achieves the driving member 40 driving the first sub-light-shielding member 311 and the second sub-light-shielding member 312 to move together, so that the first sub-light-shielding member 311 and the second sub-light-shielding member 312 move to an unfolded state or a retracted state.

[0068] When the first sub-shading member 311 moves from the extended state to the retracted state, the first sub-shading member 311 abuts against the first transmission member 211 via the roller 314, causing the first transmission member 211 to rotate. After the first transmission member 211 rotates, it drives the blocking member 22 to rotate via the second transmission member 212, causing the blocking member 22 to rotate to cover the clearance gap 202. When the first sub-shading member 311 moves from the retracted state to the extended state, the roller 314 of the first sub-shading member 311 separates from the first transmission member 211. Under the action of the elastic member 23, the first transmission member 211 drives the blocking member 22 to rotate via the second transmission member 212, causing the blocking member 22 to rotate to the clearance state.

[0069] The above are merely specific embodiments 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 equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
