Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted projection equipment, and in particular to a roof luggage rack. In addition, the utility model also relates to a vehicle. Background Art

[0002] SUVs (sport utility vehicles) often feature roof racks, which not only accommodate roof boxes but also offer a decorative touch. Furthermore, since SUVs are often used for travel and camping, roof racks are often used to mount sunshades or temporary projection screens. Installing sunshades and projection screens on roof racks enhances the enjoyment of camping and other activities, and is a key way to expand lifestyles and promote communication.

[0003] Currently, luggage racks and projection screens are typically separate structures, with no interlocking opening and closing mechanism between them. The projection screen must be carried separately, taking up storage space and creating inconvenience. Furthermore, the screen must be manually hoisted onto the luggage rack, unfolded for use, and then retracted and disassembled after use, a cumbersome and inconvenient operation that can disrupt the camping experience. Furthermore, in inclement weather, retracting and organizing the screen is even more difficult, significantly impacting the camping experience and comfort. Utility Model Content

[0004] In view of this, the present invention aims to provide a roof rack to provide a curtain configuration solution that can be automatically deployed and retracted on the roof.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A roof rack comprises a housing assembly, an extension mechanism and a screen assembly disposed within the housing assembly; the housing assembly comprises a base fixedly mounted on the vehicle roof, and a top cover snapped onto the base; the screen assembly comprises a reel rotatably disposed on the base, and a projection screen reeled onto the reel; an end of the projection screen is connected to the top cover;

[0007] The extending mechanism is disposed between the base and the top cover, and can be manipulated to drive the top cover to move up and down, thereby driving the projection screen to unfold upward from the reel, or to reel the projection screen onto the reel and fasten the top cover.

[0008] Furthermore, the stretching mechanism adopts a scissor-type connecting rod lifting mechanism.

[0009] Furthermore, the extension mechanism includes two cross links hingedly connected in the middle, and a driving device for driving the two cross links to swing relative to each other; the bottom ends of the two cross links are arranged on the base, and the top ends of the two cross links are arranged on the top cover. Swinging the two cross links to close or unfold them can drive the top cover to rise or fall.

[0010] Furthermore, the top ends of the two cross-links are movably provided on the top cover, and the driving device includes a driving motor provided on the base, and a screw driven to rotate by the driving motor; the bottom ends of the two cross-links are respectively hinged with sliding blocks, and the two sliding blocks are slidingly provided on the base, and the two sliding blocks are respectively screwed to the screw through forward threads and reverse threads, and the rotating screw drives the two sliding blocks closer to close the two cross-links, or drives the two sliding blocks away to unfold the two cross-links.

[0011] Furthermore, the screw is connected to the reel by transmission, and when the screw rotates to drive the top cover to descend, it can also drive the reel to rotate to reel in the projection screen.

[0012] Furthermore, the ends of the screw and the reel are respectively provided with a main gear and a driven gear, and the main gear and the driven gear are meshed and connected.

[0013] Furthermore, an end cover is provided at the end of the housing assembly, the drive motor is connected to the end of the screw, and the drive motor, the main gear and the driven gear are all covered in the end cover.

[0014] Furthermore, an upper track frame is provided on the top cover, a track groove is formed on the upper track frame, and rollers are respectively provided at the top ends of the two cross links, and the two rollers are both arranged in the track groove.

[0015] Furthermore, a limit block is provided on the base, and the limit block is used to limit the sliding distance of the sliding block.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The roof rack of the present invention is provided with an extension mechanism and a screen assembly within the outer shell assembly of the roof rack. The extension mechanism is used to drive the top cover of the outer shell assembly to rise and open, which can simultaneously drive the projection screen in the screen assembly to unfold. The top cover is driven to descend and close, and the reel is driven to reel in the projection screen. Therefore, the projection screen can be conveniently unfolded on the roof for projecting images and videos. After use, the projection screen can be quickly retracted and the roof rack can be returned to its original state, thereby providing a screen configuration solution that can automatically unfold and retract on the roof.

[0018] Furthermore, the roof is raised and lowered using a scissor-type linkage mechanism. This not only simplifies the structure, but also allows the lowered linkage to be compact and stowed away within the housing assembly, preserving the roof rack's aesthetic appearance. The use of two cross-links in the extension mechanism further simplifies the linkage structure, reducing the number of components and ultimately minimizing the size of the extended mechanism when lowered and stowed, contributing to a smaller overall roof rack footprint.

[0019] Another object of the present invention is to provide a vehicle equipped with the roof rack of the present invention. The vehicle of the present invention has the technical advantages of the roof rack. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] Example 1

[0039] This embodiment relates to a roof rack, which provides a curtain configuration solution that can be automatically unfolded and retracted on the roof; an exemplary structure thereof is as follows Figure 1 and Figure 2 shown.

[0040] Generally speaking, the roof rack comprises a housing assembly 1, an extension mechanism and a screen assembly 3 mounted within the housing assembly 1. The housing assembly 1 comprises a base 10 fixed to the vehicle roof and a top cover 11 snapped onto the base 10. The screen assembly 3 comprises a reel 31 rotatably mounted on the base 10, and a projection screen 30 reeled onto the reel 31. Furthermore, the ends of the projection screen 30 are connected to the top cover 11. The extension mechanism is located between the base 10 and the top cover 11 and can be manipulated to move the top cover 11 up and down, either unrolling the projection screen 30 from the reel 31 or reeling the projection screen 30 onto the reel 31 and snapping onto the top cover 11.

[0041] It should be pointed out that, based on the above-mentioned overall design concept, the technical solution of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above-mentioned extension mechanism can adopt a variety of different specific structural forms such as cylinder drive, motor drive, etc.; the specific setting sequence, installation method, etc. of the extension mechanism and the curtain assembly 3 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible design can be made with reference to the mature setting means in this field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only one of the better solutions among the many solutions that can be formed by the above-mentioned various combinations and changes. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned various specific forms and their changes, as well as the specific implementation scheme of this embodiment, are all within the scope of protection of the present utility model.

[0042] Specifically, if Figures 3 to 8As shown, the extension mechanism of this embodiment utilizes a scissor-type linkage lifting mechanism. Using a scissor-type linkage lifting mechanism, a single driver, such as a motor or cylinder, drives one of the linkages within the scissor-type lifting mechanism to swing, causing the entire lifting mechanism to rise and fall accordingly, thereby driving the top cover 11 to rise and fall. This structure is not only simple, but the lowered linkage structure is relatively small, allowing it to be easily stored within the interior of the housing assembly 1, preserving the appearance of the roof rack.

[0043] The extension mechanism comprises two cross links 23 hingedly connected at the center, and a drive mechanism for causing the two cross links 23 to swing relative to each other. The bottom ends of the two cross links 23 are mounted on the base 10, and the top ends of the two cross links 23 are mounted on the roof 11. Swinging the cross links 23 together or apart drives the roof 11 upward or downward. Using two cross links 23 in the extension mechanism simplifies the linkage structure, reduces the number of components in the extension mechanism, and ultimately reduces the size of the extension mechanism when lowered and retracted, thus reducing the overall dimensions of the roof rack.

[0044] refer to Figure 7 、 Figure 8 As shown, the top ends of the two cross links 23 are movably mounted on the top cover 11. The middle portions of the two cross links 23 are hingedly connected via a middle connecting shaft 232. The bottom ends of the two cross links 23 are hingedly connected to a front sliding block 221 and a rear sliding block 222 via a lower connecting shaft 231. The front sliding block 221 and the rear sliding block 222 are both slidably mounted on the base 10 along the front-to-back direction of the vehicle.

[0045] Based on the above-mentioned configuration, the drive device of this embodiment includes a drive motor 20 provided on the base 10, and a screw 21 driven to rotate by the drive motor 20; and two sliding blocks (a front sliding block 221 and a rear sliding block 222) are respectively threadedly connected to the screw 21 via a forward thread 211 and a reverse thread 212. The rotating screw 21 can drive the two sliding blocks closer together to retract the two cross-links 23, or drive the two sliding blocks farther apart to extend the two cross-links 23. Based on the above-mentioned transmission configuration, when the drive motor 20 drives the screw 21 to rotate, the forward thread 211 and the reverse thread 212 on the screw 21 respectively drive the two sliding blocks to move closer together or farther apart synchronously, thereby driving the two cross-links 23 to retract or extend, thereby achieving the lifting and lowering of the lifting mechanism. The top and bottom ends of the two cross-links 23 are both movable. By driving the screw 21 to rotate through the driving motor 20, the two cross-links 23 can be driven to swing synchronously, thereby improving the lifting efficiency of the link structure, and then increasing the speed of unfolding and folding the projection screen 30, which is beneficial to improving the user experience of the projection screen 30.

[0046] Furthermore, in this embodiment, the screw 21 and the reel 31 are connected in a transmission manner. The rotation of the screw 21 simultaneously drives the top cover 11 downward and drives the reel 31 to rotate, thereby retracting the projection screen 30. Specifically, the screw 21 and the reel 31 are driven by a set of meshing gears 4. A main gear 40 and a driven gear 41 are respectively provided at the ends of the screw 21 and the reel 31, and the main gear 40 and the driven gear 41 are meshed and connected.

[0047] A transmission structure is provided between the screw 21 and the reel 31. While driving the top cover 11 upward and downward, the reel 31 can correspondingly rotate to unfold or retract the projection screen 30. In particular, when the projection screen 30 needs to be retracted, the top cover 11 descends and the reel 31 retracts the projection screen 30 simultaneously. This allows the drive motor 20 to be effectively utilized to simultaneously retract the projection screen 30 and lower the top cover 11, reducing the number of drive components and increasing drive efficiency. A gear transmission structure with an appropriate transmission ratio is employed between the screw 21 and the reel 31 to effectively coordinate the lifting speed of the top cover 11 with the unfolding and retracting speed of the projection screen 30, thereby ensuring good synchronization and consistency in the movements of the top cover 11 and the projection screen 30.

[0048] Based on the above configuration, preferably, an end cap 12 is provided at the end of the housing assembly 1, and the drive motor 20 is connected to the end of the screw 21. In this way, the drive motor 20, the main gear 40, and the driven gear 41 are all covered by the end cap 12. Providing the end cap 12 at the upper end of the housing assembly 1 facilitates more flexible configuration of the size and end structure of the top cover 11, and facilitates well shielding the transmission components such as the drive motor 20, the main gear 40, and the driven gear 41 located at the ends of the screw 21 and the reel 31 within the interior of the housing assembly 1.

[0049] Regarding the arrangement of the top ends of the two cross links 23 on the top cover 11, there are of course a variety of different structural solutions to choose from. Figure 2 、 Figure 4 and Figure 6 As shown, the top cover 11 is provided with an upper track frame 25, which is also formed with a track groove 250. The top ends of the two cross-links 23 are each provided with a roller, both of which are located within the track groove 250. Specifically, the rollers include a front roller 241 and a rear roller 242, each hingedly connected to the top ends of the two cross-links 23 via an upper connecting shaft 233. To facilitate the movement of the upper connecting shaft 233 and the top ends of the cross-links 23, a long, free-falling hole can be provided in the upper track frame 25. Furthermore, to properly support the projection screen 30, the end of the projection screen 30 can be fixedly connected to an end rod 32, which can be hoisted onto the top cover 11 or the upper track frame 25. The top cover 11 and the upper track frame 25 can be fixedly connected by means of a snap connection, a screw connection, or the like.

[0050] An upper track frame 25 is provided on the top cover 11, which provides good guiding conditions for the forward and backward movement of the top ends of the two cross-links 23 on the top cover 11. By providing rollers at the ends of the cross-links 23, the movement of the top ends of the cross-links 23 on the upper track frame 25 can be changed from sliding to rolling, which is beneficial to reducing the movement resistance of the top ends of the cross-links 23 on the upper track frame 25, making the driving action of the extension mechanism smoother.

[0051] like Figure 2 、 Figure 7 or Figure 8 As shown, the base 10 of this embodiment is further provided with a limit block 26, which is used to limit the sliding distance of the sliding block. By providing multiple limit blocks 26 on the base 10, the sliding block is confined to a suitable sliding distance range, thereby limiting the driving limit position of the extension mechanism. When the top cover 11 is snapped onto the base 10, the limit blocks 26 located on the outside of the sliding block abut the sliding block. When the top cover 11 rises to the highest position (at which time the projection screen 30 is fully extended), the limit blocks 26 located on the inside of the sliding block abut the sliding block. This ensures the reliability of the entire driving action of the extension mechanism and the accuracy of the final position.

[0052] Based on the overall configuration of the roof rack described above, when the projection screen 30 is needed after parking, the drive motor 20 is controlled to rotate forward, and the screw 21 rotates accordingly to drive the two cross links 23 to retract and lift the top cover 11 upward. The upper track frame 25 and the end rod 32 connected to the top cover 11 move upward synchronously, and the end rod 32 pulls the projection screen 30 to unfold from the reel 31; until the front sliding block 221 and the rear sliding block 222 hit the inner limit block 26, the top cover 11 rises to the top position and the projection screen 30 is fully unfolded.

[0053] When the projection screen 30 needs to be folded up, the drive motor 20 is controlled to rotate in the opposite direction, and the screw 21 rotates accordingly to drive the two cross links 23 to swing outward and expand, thereby reducing the height downward and driving the top cover 11 to descend; the upper track frame 25 and the end rod 32 connected to the top cover 11 descend synchronously, and the reel 31 rotates simultaneously with the transmission of the meshing gear 4 to reel the projection screen 30 onto the reel 31; until the front sliding block 221 and the rear sliding block 222 hit the outer limit block 26, the top cover 11 descends into place and is buckled on the base 10, and the screen assembly 3, the upper track frame 25, etc. are all hidden inside the outer shell assembly 1.

[0054] In summary, the roof rack of this embodiment disposes an extension mechanism and a screen assembly 3 within the outer shell assembly 1 of the roof rack. The extension mechanism drives the top cover 11 of the outer shell assembly 1 to rise and open, which can simultaneously drive the projection screen 30 in the screen assembly 3 to unfold. The top cover 11 is driven down and locked, and the reel 31 is driven to retract the projection screen 30. Therefore, the projection screen 30 can be conveniently deployed on the roof for projecting images and videos. After use, the projection screen 30 can be quickly retracted and the roof rack can be returned to its original state, thereby providing a screen configuration solution that can be automatically deployed and retracted on the roof.

[0055] Example 2

[0056] This embodiment relates to a vehicle, on which the roof luggage rack provided in the first embodiment is provided.

[0057] By integrating the screen assembly 3 and the extension mechanism into the roof rack atop the vehicle, the screen assembly 3 can be easily deployed and retracted, creating a coordinated design that links the rise and fall of the roof rack's cover 11 with the projection screen 30. When the projection screen 30 is not in use and the vehicle is in normal motion, the projection screen 30 is retracted, and the extension mechanism and screen assembly 3 are concealed and stored within the roof rack's outer shell assembly 1. When the vehicle is parked and the projection screen 30 is needed for projection, the drive motor 20 is controlled to deploy the extension mechanism, raising the cover 11 and simultaneously deploying the projection screen 30, thereby achieving automatic deployment and retraction of the projection screen 30. This design not only maintains the appearance of the vehicle and roof rack, but also significantly enhances the vehicle's features and functionality, provides convenient operation, and enhances the user's experience of leisure activities such as camping. It also creates a strong sense of technology, increasing the product's inherent value, appeal, and competitiveness.

[0058] Compared with the existing situation where the screen assembly 3 is configured separately, the vehicle adopts the roof rack of the present invention, which does not need to occupy the storage space in the vehicle to place the screen assembly 3; moreover, when camping is over or in bad weather, the projection screen 30 can be quickly and automatically rolled up into the outer shell assembly 1 of the roof rack, which is more efficient and convenient to cope with camping scenes and provides an excellent user experience.

[0059] The above description is merely a preferred embodiment of the present invention. The detailed configuration explanations, specific structural configuration examples, and assembly connection descriptions are provided for the purpose of providing sufficient disclosure to enable those skilled in the art to better implement the present invention. They are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
