Description

Technical Field

[0001] This application relates to the field of projection technology, and more specifically, to a vehicle-mounted screen device and vehicle. Background Technology

[0002] With the development of vehicle technology, it has become possible to install screens in vehicle cabins, providing users with a richer intelligent experience. Currently, vehicle screens are often fixedly installed near the ceiling of the cabin.

[0003] In real-world scenarios, some vehicle models may be equipped with sunroofs, such as manually or electrically operated sunroofs, panoramic sunroofs (openable or non-openable), or segmented sunroofs. When a vehicle has a sunroof, on the one hand, an improper placement of the sunroof can affect its functionality; on the other hand, the placement of the sunroof is heavily dependent on the vehicle's structure.

[0004] Therefore, how to properly set up a vehicle-mounted screen has become a problem that needs to be solved. Summary of the Invention

[0005] This application provides a vehicle-mounted screen device and vehicle, which can significantly reduce the difficulty of arranging the vehicle-mounted screen when the vehicle is equipped with a sunroof, and can avoid the interference of the vehicle-mounted screen with the use of the sunroof and sunroof sunshade.

[0006] In a first aspect, a vehicle-mounted screen device is provided. The vehicle-mounted screen device (20) includes: a screen body (201), a screen guide rail (202), and a sliding mechanism (203). The screen guide rail (202) is integrated into the sunroof frame assembly (11) of the vehicle (1); the screen body (201) is fixedly connected to the sliding mechanism (203), and the sliding mechanism (203) is slidably connected to the screen guide rail (202).

[0007] In this embodiment, since the screen body (201) is fixedly connected to the sliding mechanism (203), and the sliding mechanism (203) is slidably connected to the screen guide rail (202), the screen body (201) can move relative to the screen guide rail (202) in the guiding direction. On the one hand, it allows users to adjust the position of the screen body (201) according to their needs, so that the arrangement of the screen body (201) is no longer limited by the distribution of seats and other devices in the cabin, and can avoid the screen body (201) affecting the user's use of the skylight and skylight sunshade. On the other hand, when the user is using the screen, they can adjust the viewing distance by adjusting the position of the screen body (201), so that the user does not need to adjust their own position, which can improve the user experience.

[0008] Furthermore, since the curtain guide rail (202) is integrated into the sunroof frame assembly (11), the curtain guide rail (202) can be covered by the vehicle's interior trim, which helps to reduce the deterioration of the cabin's aesthetic appearance caused by the curtain guide rail (202). In addition, compared to the solution of setting the curtain guide rail (202) in other locations on the vehicle (such as on the chassis or other load-bearing devices), integrating the curtain guide rail (202) into the sunroof frame assembly (11) can reduce the distance between the curtain body (201) and the curtain guide rail (202), and a smaller / lighter sliding mechanism (203) can be used to fix the curtain body (201), which helps to reduce the cost of parts.

[0009] In some possible implementations, the vehicle-mounted screen device (20) may also include a braking mechanism (206). The braking mechanism (206) can be used to maintain the relative position between the screen body (201) and the screen guide rail (202) in the braking state.

[0010] In this embodiment of the application, by setting a braking mechanism, the main body of the screen (201) can be kept in the current position without moving along the screen guide rail (202), which can prevent the main body of the screen (201) from moving along the screen guide rail when the screen is in use, thus affecting the user's viewing experience.

[0011] In some possible implementations, the braking mechanism (206) may include a switch (2061), a transmission element (2062), an elastic element (2063), and a brake block (2064). The elastic element (2063) may be used to provide pressure for the brake block (2064) to adhere to the curtain guide rail (202) in the braking state. The transmission element (2062) may drive the brake block (2064) to the switch (2061), wherein movement of the switch (2061) in a first direction may cause movement of the brake block (2064) in a second direction, so that the braking mechanism (206) is in a braking state or a de-braking state.

[0012] In this embodiment, by providing an elastic element (2063), the braking mechanism (206) can maintain the main body of the curtain (201) in the current position without user operation; by providing a transmission element (2062), the braking mechanism (206) can enter / deactivate the braking state with a relatively simple structure, which is beneficial to simplifying the structure of the braking mechanism.

[0013] In some possible implementations, a magnetic element (207) may be provided at the end of the curtain guide rail (202). The magnetic element (207) may be used to magnetically fix the sliding mechanism (203) when it is at that end.

[0014] In this embodiment, when the position of the curtain body (201) is adjusted to the end of the curtain guide rail (202), by providing a magnetic element (207) at the end of the curtain guide rail (202), a magnetic force can be applied to the sliding mechanism (203) to keep the curtain body (201) in the current position, which can prevent the curtain body (201) from moving due to vehicle braking / acceleration.

[0015] In some possible implementations, the vehicle-mounted screen device (20) may also include a wiring harness (204) and a cable chain (205). The cable chain (205) may include a fixed end and a movable end, and the cable chain (205) may be provided with a wiring harness track; the wiring harness (204) may be provided in the wiring harness track, and one end of the wiring harness (204) extending from the movable end may be connected to the screen body (201).

[0016] In this embodiment of the application, by setting the wire harness (204) on the wire harness track of the drag chain (205), it is possible to prevent the wire harness (204) from being twisted / knotted / damaged due to the movement of the curtain body (201), which is beneficial to improving the service life of the wire harness (204).

[0017] In some possible implementations, the sliding mechanism (203) may include a rolling element and a bracket (2031). One end of the bracket (2031) may be connected to the screen body (2031), and the other end of the bracket (2031) may be connected to the rolling element, which may fit against the screen guide rail (202).

[0018] In this embodiment of the application, by setting a rolling element, the sliding mechanism (203) and the curtain guide rail (202) can form a rolling guide rail pair, which can reduce the resistance when the sliding mechanism (203) moves, and make the sliding process of the curtain device (201) along the curtain guide rail (202) smoother.

[0019] In some possible implementations, the guiding direction of the curtain guide rail (202) may have a component along the longitudinal axis of the vehicle (1).

[0020] In this embodiment, since the guiding direction of the screen guide rail (202) has a component along the longitudinal axis of the vehicle, the user can adjust the position of the screen body (201) in the longitudinal axis of the vehicle, so that the user can adjust the viewing distance without adjusting their own position, which can improve the user experience.

[0021] In some possible implementations, the curtain guide rail (202) is integrated into the sunroof frame assembly (11) of the vehicle (1), and may include: the curtain guide rail (202) being fixedly connected to the sunroof frame assembly (11) by fasteners.

[0022] In this embodiment, the curtain guide rail (202) is fixedly connected to the sunroof frame assembly (11) by fasteners, which facilitates the maintenance of the curtain device (20). For users, when the sunroof frame assembly (11) or the curtain guide rail (202) is damaged or deformed, only the damaged or deformed parts can be replaced, which can reduce maintenance costs. For vehicle manufacturers, the various models they produce may have different types of sunroofs, and the configurations of the same model may be equipped with different types of sunroofs. Since the curtain guide rail (202) and the sunroof frame assembly (11) are two detachable devices, the curtain guide rail (202) can be applied to various different models and various configurations of the same model, which helps to reduce the mold and development costs of the curtain guide rail (202) and can improve the versatility of the curtain guide rail (202).

[0023] In some possible implementations, the curtain guide rail (202) is integrated into the sunroof frame assembly (11) of the vehicle (1), and may include: the sunroof frame assembly (11) is provided with a guide structure that can be slidably connected to the sliding mechanism (203).

[0024] In this embodiment, the guide structure of the sunroof frame assembly (11) serves as the curtain guide rail (201), which can reduce the assembly time of the curtain device and improve the production efficiency of the vehicle.

[0025] In some possible implementations, the rear end of the curtain rail (202) may extend toward the rear of the vehicle (1) relative to the rear end of the sunroof frame assembly (11).

[0026] In real-world scenarios, some sunroofs are relatively short in the longitudinal direction of the vehicle, and the rear end of their sunroof frame assembly (11) may still be positioned relatively far forward, such as near the back of the first row of seats. If the rear end of the curtain guide rail (202) is flush with the sunroof frame assembly (11), the curtain device (20) may still have a significant detrimental effect on the aesthetics of the cabin, and the curtain may be disturbed by the seats when it is unfolded.

[0027] In this embodiment, by extending the rear end of the curtain guide rail (202) relative to the rear end of the sunroof frame assembly (11) toward the rear of the vehicle, the deteriorating effect of the curtain device (20) on the aesthetic appearance of the cabin can be reduced, and the interference of the seat on the unfolded state of the curtain can be avoided.

[0028] In some possible implementations, a sunroof curtain guide rail is provided on the sunroof frame assembly (11), and the curtain guide rail (202) may be different from the sunroof curtain guide rail.

[0029] Because skylight sunshade curtains are relatively lightweight, their guide rails often have low strength and rigidity, making them unsuitable for bearing heavy loads. In this embodiment, the curtain guide rail (202) is set to be different from the skylight sunshade curtain guide rail, which helps to ensure the reliability of the curtain device (20).

[0030] In a second aspect, a vehicle is provided that may include the vehicle-mounted screen device described in the first aspect and any possible implementation thereof. Attached Figure Description

[0041] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0042] The following detailed description and accompanying drawings of the embodiments are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

[0043] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and other forms such as the third-person singular "comprises" and the present participle "comprising" are interpreted as open and inclusive, meaning "including, but not limited to." In the description, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this application. The illustrative representations of the foregoing terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be included in any suitable manner in any of the embodiments or examples.

[0044] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0045] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structures in the embodiments of this application. It should also be noted in the description of the embodiments of this application that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In this application, the term "embodiment" is used to mean that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Those skilled in the art will explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0047] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0048] In addition, the use of “based on” implies openness and inclusivity, because a process, step, calculation or other action “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0049] The terms “about,” “approximately,” or “approximately” used in this application embodiment include the stated value and the average value within an acceptable deviation range of a particular value, wherein the acceptable deviation range is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity, i.e., the limitations of the measurement system.

[0050] Currently, vehicle-mounted screens are typically fixed near the ceiling. When in use, the screen can be unfolded vertically to form a projection area. However, due to the presence of seats and other fixtures in the cabin, to avoid interference with the screen when unfolded, the vehicle-mounted screen is usually placed outside the area occupied by the seats along the vehicle's longitudinal axis. This severely restricts the placement of the vehicle-mounted screen due to the distribution of other fixtures within the cabin.

[0051] Furthermore, in real-world scenarios, some vehicle models are equipped with sunroofs, such as manually or electrically operated sunroofs, panoramic sunroofs (openable or non-openable), and segmented sunroofs. The presence of sunroofs further complicates the placement of in-vehicle screens, and an improper placement may affect the sunroof's functionality.

[0052] For example, Figure 1 A schematic diagram of a cockpit scene is shown. Figure 1 This can be understood as the viewpoint from the rear seats of the cabin when looking at the sunroof.

[0053] like Figure 1 As shown, the vehicle is equipped with a sunroof, and the screen is fixedly installed on the vehicle. For openable sunroofs, an improper placement of the screen may affect its opening and closing. For non-openable panoramic sunroofs, if the screen is not positioned correctly, from the user's perspective, the screen may divide the panoramic sunroof into front and rear sections, significantly detracting from the aesthetic appeal of the sunroof and the cabin. Figure 1 As shown. Furthermore, some models are equipped with retractable sunroof sunshades; an unreasonable arrangement of the sunroof sunshade may also affect the user's ability to use it. Figure 1The screen shown is in the retracted state; when the screen is unfolded vertically, it may be disturbed by the chair.

[0054] In addition, since the vehicle screen is fixed on the vehicle, the viewing distance between the user and the screen can only be adjusted by the user adjusting their own position.

[0055] Therefore, this application provides a screen device that can meet different user needs when a vehicle is equipped with a sunroof.

[0056] For example, Figure 2 This is a schematic diagram of a skylight arrangement provided in an embodiment of this application.

[0057] like Figure 2 As shown, vehicle 1 may be equipped with a sunroof frame assembly 11, a sunroof glass assembly 12, an exterior styling mechanism 13, and an interior styling mechanism 14. Figure 1 This can be understood as a partial view of a section along the longitudinal axis of vehicle 1. To prevent rainwater, dust, etc. from entering the vehicle, the sunroof frame assembly 11, the sunroof glass assembly 12, and / or the vehicle's external styling mechanism 13 may include seals.

[0058] The sunroof frame assembly 11 (hereinafter referred to as sunroof frame 11) can support the sunroof glass assembly 12. For example, for an openable / closed sunroof, the guide rail device 11 can support the sunroof glass assembly 12.

[0059] The sunroof frame assembly 11 may include a frame 111 and seals, such as seals 112 and 113 disposed on the frame 111. The frame 111 may be composed of one or more frame components, such as multiple sheet metal parts welded / riveted / bolted together.

[0060] In some possible implementations, the sunroof frame assembly 11 may also include a sunroof guide rail. For example, for an operable sunroof, the sunroof frame assembly 11 may also guide the opening and closing of the sunroof glass 12 via the sunroof guide rail.

[0061] The sunroof glass assembly 12 (hereinafter referred to as sunroof glass 12) may include a glass panel 121 and a deflector 122; it may also include a seal 123. For example, when the sunroof glass 12 is closed, the seal 113 and the seal 123 can cooperate to achieve a sealing effect, preventing rainwater / fallen leaves / dust, etc., from entering the cabin. As another example, the deflector 122 can cooperate with the seal 132 to achieve a sealing effect, preventing rainwater, dust, etc., from entering the cabin. When rainwater flows into the vehicle through the gap between the deflector 122 and the seal 132, the rainwater is guided to the frame 111 by the deflector 122. At this time, the frame 111 can also guide the rainwater to the drainage mechanism (…). Figure 2 (Not shown), rainwater is drained out of the vehicle through a drainage system.

[0062] The vehicle's external styling mechanism 13 may include a roof 131 and may also include seals, such as seal 132. For example, when the sunroof glass 12 is closed, seals 122 and 132 can cooperate to achieve a sealing effect, preventing rainwater, dust, etc. from entering the cabin.

[0063] In some embodiments, seals 12, 113, and 132 may be rubber strips.

[0064] The vehicle's interior styling mechanism 14 can form the outline of the cabin. For example, the vehicle's interior styling mechanism 14 can be composed of one or more interior trim panels.

[0065] In some possible implementations, vehicle 1 may also be equipped with a sunroof sunshade 15, such as Figure 2 As shown. The sunroof frame assembly 11 can support the sunroof sunshade 15, and can also guide the movement of the sunshade 15 through the sunshade guide rail set on the sunroof frame assembly 11.

[0066] For example, Figure 3 This is a schematic diagram illustrating the arrangement of a vehicle-mounted screen device according to an embodiment of this application. Figure 3 In, with Figure 2 Devices with the same / similar structure and / or function as those in the above, employing the same... Figure 2 The same number in the middle.

[0067] like Figure 3 As shown, the vehicle-mounted screen device 20 (hereinafter referred to as screen device 20) may include a screen body 201, a screen guide rail 202, and a sliding mechanism 203. The screen body 201 is fixedly connected to the sliding mechanism 203, and the sliding mechanism 203 is slidably connected to the screen guide rail 202.

[0068] For example, the curtain body 201 may include a take-up roller and part or all of the curtain wound on the take-up roller. As another example, when the curtain assembly 20 is capable of automatically unfolding / retracting in a vertical direction, the curtain body 201 may also include a drive mechanism (such as a motor) for the take-up roller. As yet another example, the curtain body 201 may also include a transmission device for drivingly connecting the take-up roller to the drive mechanism.

[0069] For example, the curtain guide rail 202 can be integrated into the skylight frame assembly 11. For instance, the curtain guide rail 202 can be fixedly connected to the skylight frame assembly 11 by processes such as riveting or welding.

[0070] In one embodiment, the sunroof frame assembly 11 may include multiple components such as a frame 111 and a sunroof guide rail, and the curtain guide rail 202 may be integrated into any component. For example, the curtain guide rail 202 may be integrated into the frame 111, and the curtain guide rail 202 may be integrated into the sunroof guide rail.

[0071] The sliding mechanism 203 may include one or more components. For example, such as Figure 3 As shown, the sliding mechanism 203 may include a bracket 2031 and a connecting rod 2032. The connecting rod 2032 may be coupled to the bracket 2031. Alternatively, the connecting rod 2032 may also be understood as a component of the bracket 2031.

[0072] For example, the bracket 2031 can form a sliding guide rail pair / rolling guide rail pair with the screen guide rail 202, so that the bracket 2031 can move relative to the screen guide rail 202 in the guiding direction of the screen guide rail 202. One end of the connecting rod 2032 can be fixedly connected to the bracket 2031, and the other end of the connecting rod 2032 can be fixedly connected to the screen body 201.

[0073] In one embodiment, taking a sliding guide rail pair as an example, one of the curtain guide rail 202 and the bracket 2031 can be provided with a convex structure, and the other can be provided with a concave structure. The convex and concave structures can cooperate to form a sliding guide rail pair, allowing the bracket 2031 to slide relative to the curtain guide rail 202. In this scenario, the bracket 2031 can be considered as a slider that can slide along the guide rail 202.

[0074] In this embodiment, since the screen body 201 is fixedly connected to the sliding mechanism 203, and the sliding mechanism 203 is slidably connected to the screen guide rail 202, the screen body 201 can move relative to the screen guide rail 202 in the guiding direction of the screen guide rail 202. On the one hand, it allows users to adjust the position of the screen body 201 according to their needs, avoiding the screen body 201 from affecting the user's use of the skylight and skylight sunshade, so that the arrangement of the screen body is no longer limited by the distribution of seats and other devices in the cabin. On the other hand, when using the screen, users can adjust the viewing distance by adjusting the position of the screen body, so that users do not need to adjust their own position, which can improve the user experience.

[0075] Furthermore, since the curtain guide rail 202 is integrated into the sunroof frame assembly 11, it can be concealed by the vehicle's interior trim, which helps reduce the deterioration of the cabin's aesthetic appearance. Additionally, compared to placing the curtain guide rail 202 on other vehicle components (such as the chassis or other load-bearing devices), integrating it into the sunroof frame assembly 11 reduces the distance between the curtain body 201 and the curtain guide rail, thereby reducing the size and weight of the sliding mechanism 203 used to fix the curtain body 201 and lowering component costs.

[0076] In some possible implementations, in order to facilitate the disassembly and replacement of the curtain device 20, the curtain guide rail 202 can be fixedly connected to the skylight frame assembly 11 by fasteners (such as bolt connection, screw connection, etc.), so that the curtain guide rail 202 is integrated into the skylight frame assembly 11.

[0077] In this embodiment, the curtain guide rail 202 is fixedly connected to the sunroof frame assembly 11 using fasteners, facilitating the maintenance of the curtain device 20. For users, when the sunroof frame assembly or curtain guide rail is damaged or deformed, only the damaged or deformed parts need to be replaced, reducing vehicle maintenance costs. For vehicle manufacturers, various models they produce may have different sunroofs, and configurations of the same model may have different sunroof types. Since the curtain guide rail 202 and the sunroof frame assembly 11 are two detachable parts, the curtain guide rail 202 can be fixedly connected to the frame assembly of different sunroof types using fasteners. This allows it to be applicable to various different models and various configurations of the same model, reducing mold and development costs for the curtain guide rail 202 and improving its versatility.

[0078] In some possible implementations, the skylight frame assembly 11 may be provided with a guide structure that can be slidably connected to the sliding mechanism 203. That is, the curtain guide rail 202 may be coupled to the skylight frame assembly 11, and the skylight frame assembly 11 has a guide structure that guides the movement of the sliding mechanism 203. For example, the skylight frame assembly 11 and the curtain guide rail 202 may be coupled as a single unit using a one-piece molding process.

[0079] In this embodiment, the guide structure in the sunroof frame assembly 11 serves as the curtain guide rail 201, which can reduce the assembly time of the curtain device and improve the production efficiency of the vehicle.

[0080] For example, the guiding direction of the curtain rail 202 may have a component along the longitudinal axis of the vehicle. For instance, the curtain rail 202 may be positioned along the extending direction of the frame 111. The extending direction of the frame 111 may be the longitudinal axis of the vehicle; alternatively, the extending direction of the frame 111 may have a component along the longitudinal axis of the vehicle and a component along the vertical direction. As another example, the guiding direction of the curtain rail 202 may differ from the extending direction of the frame 111, and there may be an angle between them.

[0081] In this embodiment, since the guiding direction of the screen guide rail 202 has a component along the longitudinal axis of the vehicle, the user can adjust the position of the screen body 201 in the longitudinal axis of the vehicle, so that the user can adjust the viewing distance without adjusting their own position, which can improve the user experience.

[0082] In some possible implementations, the rear end of the curtain rail 202 extends toward the rear of the vehicle relative to the rear end of the sunroof frame assembly 11. For example, the rear end of the curtain rail 202 can extend to the rear seats of the vehicle, or even into the luggage compartment at the rear of the vehicle.

[0083] In real-world scenarios, some sunroofs are relatively short along the vehicle's longitudinal axis. In this direction, the rear end of the sunroof frame assembly 11 may still be positioned too far forward, such as near the back of the first-row seats. If the rear end of the curtain guide rail 202 is flush with the sunroof frame assembly 11, the curtain device 20 may still significantly detract from the aesthetics of the cabin, and the curtain may be affected by the seats when it is deployed.

[0084] In this embodiment, by extending the rear end of the curtain guide rail 202 relative to the rear end of the sunroof frame assembly 11 toward the rear of the vehicle, the deteriorating effect of the curtain device 20 on the aesthetic appearance of the cabin can be reduced, and the curtain can be prevented from being interfered with by the seats when it is unfolded.

[0085] For example, the curtain assembly 20 may also include a wiring harness 204. This wiring harness can be used to power the curtain assembly 20. For instance, the curtain body 201 may include a motor that drives the take-up roller to rotate, and this motor can be powered through the wiring harness 204. As another example, the curtain assembly 20 may include a motor that drives the sliding mechanism 203 to move along the guide direction of the curtain guide rail 202, and this motor can be powered through the wiring harness 204.

[0086] In some possible implementations, an electrical appliance, such as a drive motor for the take-up roller, is located on one side of the curtain assembly 201. Correspondingly, one end of the wiring harness 204 can be connected to the curtain body 201. The other end of the wiring harness 204 can be directly or indirectly connected to a power supply device (such as a vehicle battery). For ease of explanation, the end of the wiring harness 204 connected to the electrical appliance is referred to as the power-consuming end, and the end connected to the power supply device is referred to as the power-supply end.

[0087] Suppose that electrical appliances are installed on one side of the main curtain body 201. Since the main curtain body 201 can move relative to the curtain guide rail 202 along the guide direction, a relatively long wiring harness 204 is often required to supply power to these appliances, ensuring that the power supply terminals of the wiring harness 204 can be electrically connected to these appliances regardless of the position of the main curtain body 201. However, when the wiring harness 204 is long, as the power supply terminals of the wiring harness 204 move with the main curtain body 201, the middle portion of the wiring harness 204 may become twisted, knotted, or damaged, affecting the lifespan of the wiring harness.

[0088] For example, to avoid twisting / knotting / damage to the wiring harness 204 caused by movement of the curtain body 201, the curtain device 20 may be equipped with a cable chain 205 (also referred to as a tank chain 205). The cable chain 205 may include a fixed end and a movable end, and may include a wiring harness track for mounting the wiring harness. For example, the fixed end of the cable chain 205 may be fixedly connected to the vehicle, making it stationary relative to the vehicle; the portion of the wiring harness 204 extending from the fixed end of the cable chain 205 may be electrically connected to the vehicle's power supply. As another example, the portion of the wiring harness 204 extending from the movable end of the cable chain 205 may be connected to the curtain body 201 via the gap between the vehicle's interior trim 14 and the sunroof frame assembly 11, such as... Figure 2 As shown.

[0089] For example, Figure 4 This is a schematic diagram of a drag chain provided in an embodiment of this application.

[0090] like Figure 4As shown, the cable chain 205 can be composed of multiple components 2051. For example, the accommodating space enclosed by the side plates, top plate, and bottom plate on both sides of component 2051 can form a wire harness track to constrain the posture of the wire harness within the accommodating space. Alternatively, adjacent components 2051 can interlock to form a rotating joint, allowing adjacent components 2051 to rotate relative to each other within a certain angular range. When the power supply terminal of the wire harness 204 moves with the curtain body 201, the shape of the cable chain 205 will change.

[0091] The above Figure 4 The cable chain structure shown is merely an example; other forms of cable chains can also be used, and this application does not limit this.

[0092] In this embodiment, by placing the wire harness 204 on the wire harness track of the drag chain 205, it is possible to prevent the wire harness 204 from twisting / knotting / damaging caused by the movement of the curtain body 201, which is beneficial to improving the service life of the wire harness.

[0093] In some possible implementations, the bending radius of the cable chain 205 is greater than or equal to a first threshold. For example, the first threshold is 25 mm or 30 mm, or it can be determined according to the specific dimensions of the cable harness.

[0094] Because the main body of the screen 201 can move relative to the screen guide rail 202 in its guiding direction, when the screen is not in use, the user may tend to adjust the main body of the screen 201 to the end of the screen guide rail 202 to avoid affecting the use of components such as the skylight and skylight sunshade. When the screen needs to be used, the user will adjust it to the desired position so that the screen unfolds vertically to form a projection area.

[0095] In some possible implementations, the ends of the screen guide rail 202 may be provided with magnetic elements, which can be used to magnetically fix the sliding mechanism when it is at the end of the guide rail. For example, magnets may be provided at the front end and / or rear end of the screen guide rail 202; the sliding mechanism 203 may be made of ferromagnetic material, or may be provided with components of ferromagnetic material, so that the magnets can provide magnetic force to the sliding mechanism.

[0096] In this embodiment of the application, when the position of the curtain body 201 is adjusted to the end of the curtain guide rail 202, the curtain body 201 can be kept in the current position by applying magnetic force to the sliding mechanism 203, which can prevent the curtain body 201 from moving due to vehicle braking / acceleration.

[0097] The above Figure 3 Only the structure of one end of the curtain body 201 and the corresponding guide rail 202 are shown. For example, at the other end of the curtain body 201, the curtain device 20 may have... Figure 3 The symmetrical structure shown can also be equipped with corresponding guide rails. For example, in some possible implementations, the other side of the main curtain body 201 can even be suspended in mid-air.

[0098] In some embodiments, guide rails 202 and sliding mechanisms 203 may be provided on both sides of the main body 201 of the screen. For easy distinction, the suffixes "-1" and "-2" can be used to distinguish the components located on the left and right sides of the main body 201 of the screen. For example, the guide rails 202 on the left and right sides can be referred to as guide rail 202-1 and guide rail 202-2, respectively. As another example, one end of the main body 201 of the screen can be fixedly connected to the bracket 2031-1 through the connecting rod 2032-1, and the bracket 2031-1 and the guide rail 202-1 can form a sliding guide rail pair / rolling guide rail pair; the other end of the main body 201 of the screen can be fixedly connected to the bracket 2031-2 through the connecting rod 2032-2, and the bracket 2031-2 and the guide rail 202-2 can form a sliding guide rail pair / rolling guide rail pair.

[0099] In some possible implementations, the curtain device 20 may also include a braking mechanism 206. The braking mechanism 206 can be used to maintain the relative position between the curtain body 201 and the curtain guide rail 202 in a braking state.

[0100] In this embodiment of the application, by setting a braking mechanism, the main body of the screen 201 can be kept in the current position without moving along the screen guide rail 202, which can prevent the main body of the screen 201 from moving along the screen guide rail when the screen is in use, thus affecting the user's viewing experience.

[0101] In some possible implementations, the braking mechanism 206 may include a switch 2061, a transmission member 2062, an elastic member 2063, and a brake block 2064. The elastic member 2063 can provide pressure for the brake block 2064 to adhere to the curtain guide rail 202 during braking. The transmission member 2062 can drive the brake block 2064 to the switch 2061; wherein, movement of the switch 2061 in a first direction drives movement of the brake block 2062 in a second direction, thereby putting the braking mechanism 206 into a braking state or releasing the braking state. For example, static friction, a snap-fit ​​structure, or other methods can be used to keep the brake block 2064 relatively stationary with respect to the curtain guide rail 202, thus putting the curtain body 201 into a braking state. For example, the elastic force generated by the deformation of the elastic element 2063 can be directly applied to the brake block 2064; or, the elastic force can also be applied to the transmission element 2062, and the transmission rod 2063 can transmit it to the brake block 2064, so that the elastic element 2063 can provide the pressure of the brake block 2064 against the curtain guide rail 202.

[0102] The following combination Figures 5 to 7The actuation methods of the transmission component 2062, the elastic component 2063, and the brake block 2064 are described by way of example.

[0103] For example, Figure 5 This is a schematic diagram of a braking mechanism provided in an embodiment of this application.

[0104] like Figure 5 As shown, the transmission component 2062 can rotate along the shaft 2065. For example, the transmission component 2062 can be a tie rod, or it can be composed of multiple connecting rods.

[0105] Taking the brake block 2064-1 on the left as an example, the working method of the braking mechanism 206 is briefly explained.

[0106] When the user does not press switch 2061, the braking mechanism 206 can be in a braking state. At this time, the elastic element 2063-1 can be in a compressed state. Since the transmission element 2062-1 can rotate around the shaft 2065-1, the pressure exerted by the elastic element 2063-1 on the transmission element 2062-1 can be converted into the pressure of the brake block 2064-1 against the curtain guide rail 202-1. Thus, the elastic element 2063-1 can provide the pressure for the brake block 2064-1 to adhere to the curtain guide rail 202-1.

[0107] When the user presses switch 2061, switch 2061 moves in direction 1, and transmission component 2062-1 rotates along shaft 2065-1, thereby driving brake block 2064-1 to rotate. When brake block 2064-1 rotates, it has a component moving in direction 2. During the process of the user pressing switch 2061, the pressure exerted by brake block 2064-1 on guide rail 202-1 can gradually decrease until brake block 2064-1 no longer adheres to guide rail 202-1. When the user releases switch 2061, since spring 2063-1 is still in a compressed state, elastic component 2063-1 can apply pressure to transmission component 2062-1, and switch 2061 will move in direction 1 to return to its initial position. Brake block 2064-1 will move in direction 2 until it adheres to guide rail 202-1.

[0108] For example, Figure 6 This is a schematic diagram of another braking mechanism provided in an embodiment of this application. Taking the brake block 2064-1 on the left as an example, the working method of the braking mechanism 206 will be briefly explained.

[0109] exist Figure 6 In the illustrated scheme, when the user does not press switch 2061, the elastic element 2063-1 can be in a stretched state. The tension exerted by the elastic element 2063-1 on the transmission element 2062-1 can be converted into pressure of the brake block 2064-1 against the curtain guide rail 202-1, so that the braking mechanism 206 can be in a braking state.

[0110] and Figure 5 Similarly, when the user presses switch 2061, the movement of switch 2061 along direction 1 will cause brake block 2064-1 to move along direction 2. During the pressing of switch 2061, the pressure exerted by brake block 2064-1 on guide rail 202-1 gradually decreases until brake block 2064-1 no longer adheres to guide rail 202-1. When the user releases switch 2061, under the pulling force of elastic element 2063-1, switch 2061 will move along direction 1 back to its initial position, and brake block 2064-1 will move along direction 2 until it adheres to guide rail 202-1.

[0111] For example, Figure 7 This is a schematic diagram of another braking mechanism provided in an embodiment of this application.

[0112] and Figure 5 , Figure 6 The methods shown are different, such as Figure 7 As shown, one end of the elastic element 2063 can be directly connected to the brake block 2064. The elastic element 2063 can directly provide pressure to the brake block 2064 to make it conform to the curtain guide rail 202. Figures 5 to 7 The dotted line can be understood as the housing of the internal structure of the curtain device 20 used to block the braking mechanism 206.

[0113] In this embodiment, by providing the elastic element 2063, the braking mechanism 206 can maintain the main body of the curtain 201 in the current position without user operation; by providing the transmission element 2062, the braking mechanism 206 can enter and release the braking state with a relatively simple structure, which is beneficial to simplifying the structure of the braking mechanism.

[0114] The following combination Figure 8 The following is an example of how the brake block 2064 and the guide rail 202 are fitted together.

[0115] For example, Figure 8 This is a schematic diagram illustrating the contact method between the brake block 2064 and the guide rail 202 provided in an embodiment of this application. Figure 8 In the middle, brake block 2064 can correspond to Figures 5 to 7 Brake block 2064-1 or 2064-2 in the middle; correspondingly, in Figure 8 In the middle, the curtain guide rail 202 can correspond to Figures 5 to 7 The curtain guide rail is 202-1 or 202-2.

[0116] In one embodiment, the surface of the curtain guide rail 202 that is used to abut the brake block 2064 can be a plane. For example, as Figure 8 The bonding method shown is 1.

[0117] In another embodiment, on the mating surfaces of the curtain guide rail 202 and the brake block 2064, the curtain guide rail 202 and the brake block 2064 may be respectively provided with concave and convex structures. For example, as Figure 8 The bonding method shown is 2.

[0118] In this embodiment, when the contact surface is provided with matching concave and convex structures, the braking mechanism 206 can still achieve a good braking effect even when a small pressure is applied to the braking block 2064. In other words, a good braking effect can be achieved using an elastic element 2063 with a small elastic coefficient. In this scenario, because the elastic element 2063 has a small elastic coefficient, the user will experience less resistance when pressing the switch 2061. This reduces user complaints about the switch 2061 being unresponsive.

[0119] In some possible implementations, the sliding mechanism 203 may include a bracket 2031 and a rolling element. One end of the bracket 2031 is connected to the curtain body 201, and the other end of the bracket 2031 may be connected to the rolling element, which is disposed within the curtain guide rail 202.

[0120] Assuming the rolling element mentioned above is a ball bearing, the following is combined with... Figure 9 The structure of the sliding mechanism 203 is illustrated by way of example.

[0121] For example, Figure 9 This is a schematic diagram of the structure of a sliding mechanism 203 provided in an embodiment of this application. Figure 9 (a) to (c) can be understood as different perspectives of the sliding mechanism 203. For example, Figure 9 (a) in the figure can be understood as a side view of the sliding mechanism 203; Figure 9 (b) in the figure can be understood as the front view of the sliding mechanism 203; Figure 9 (c) in the figure can be understood as a top view of the sliding mechanism 203. Figure 9 The perspective adopted in (b) can be compared with... Figure 3 The same perspective was used.

[0122] exist Figure 9 In the middle, the different surfaces on the curtain guide rail 202 can be respectively designated as surfaces 202a to 202c. For example... Figure 9As shown, a ball bearing can contact surface 202a or surface 202b. The bracket 2031 can be provided with a structure to accommodate the ball bearing, and pressure can be applied to the ball bearing by a spring, thereby allowing the ball bearing to conform to the screen guide rail 202. The bracket 2031 can support one or more rows of ball bearings. For example, the bracket 2031 can be connected to the screen body 201 via a connector 2032. In some implementations, the connector 2032 can be coupled to the bracket 2031, meaning they can be the same component.

[0123] exist Figure 9 In the illustrated scheme, multiple surfaces 202a to 202c of the guide rail 202 form a cavity, and the sliding mechanism 203 can be disposed within this cavity. Among some possible implementations, [the following is related to...] Figure 9 In different ways, multiple surfaces of the sliding mechanism 203 can form a cavity, and the guide rail 202 can be disposed in the cavity.

[0124] Figure 9 The ball shown can be considered as an example of a rolling element in the sliding mechanism 203. In this scenario, the sliding mechanism 203 and the curtain guide rail 202 can form a ball bearing guide pair through the ball bearing. In some possible implementations, the rolling element in the sliding mechanism 203 can be a needle roller or a ball bearing; correspondingly, the sliding mechanism 203 and the curtain guide rail 202 can form a needle roller guide pair or a ball bearing guide pair. This application embodiment does not limit the specific type of the rolling element.

[0125] In this embodiment, by setting a rolling element, the sliding mechanism 203 and the curtain guide rail 202 can form a rolling guide rail pair, which can reduce the friction between the sliding mechanism 203 and the curtain guide rail 202, making the movement of the curtain device 201 along the curtain guide rail 202 smoother.

[0126] Assuming the braking mechanism 206 adopts the following... Figure 5 The structure shown is such that the sliding mechanism 203 adopts the following... Figure 9 The structure shown. The following is combined with... Figure 10 The relative positional relationships between the components in the curtain device 20 are described.

[0127] For example, Figure 10 This is a schematic diagram showing the relative positional relationship between multiple components of the curtain device provided in the embodiments of this application. Figure 10 In (a) and (b), the same as... Figure 9 (a) is the same perspective; Figure 10 The perspective adopted in (c) is the same as... Figure 9 The perspective is the same as that in (c).

[0128] In one embodiment, such as Figure 10As shown in (a), a magnetic element 207 (such as a magnet) can be provided at the end of the guide rail 202. When the sliding mechanism 203 moves to the end of the guide rail 202, the magnetic element 207 can magnetically fix the sliding mechanism 203. In this way, the sliding mechanism 203 can be prevented from moving along the curtain guide rail 202 during vehicle movement.

[0129] In yet another embodiment, such as Figure 10 As shown in (b) and (c), the sliding mechanism 203 and the braking mechanism 206 can be arranged side by side in the guiding direction of the curtain guide rail 202. The other components of the sliding mechanism 206, except for the transmission component 2062 and the braking block 2064, are not... Figure 10 As shown in (b) and (c).

[0130] In another embodiment, the braking mechanism 206 can also be integrated into the sliding mechanism 203. For example, the connecting rod 2032 has a through hole, and the transmission member 2062 can be disposed in the through hole; the bracket 2031 can have a through hole, and the braking block 2064 can be disposed in the through hole and can move within the through hole. In this way, the volume occupied by the curtain device 20 can be reduced.

[0131] In some possible implementations, when the skylight frame assembly 11 is equipped with a guide rail for the skylight sunshade, the guide rail often has low strength and rigidity due to the light weight of the skylight sunshade, making it unsuitable for bearing heavy loads. The curtain guide rail 202 should be a different guide rail from the skylight sunshade guide rail. Furthermore, when integrated into the skylight frame assembly 11, the curtain guide rail 202 should be integrated in a location other than the skylight sunshade guide rail to ensure the reliability of the curtain device 20.

[0132] This application embodiment also provides a sunroof frame assembly, which integrates... Figures 3 to 10 The curtain guide rail 202 in any of the above schemes is used to slide in connection with the sliding mechanism 203, which is fixedly connected to the curtain body 201.
