Description

Technical Field

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

[0002] With the upgrading of car consumption concepts, the function of cars has shifted from a simple means of transportation to a multifunctional leisure space. SUVs and MPVs, due to their larger interior space, have become popular choices for roof extensions. Through the use of a pop-up roof structure, the vehicle can expand its vertical space while parked, providing users with diversified usage scenarios such as camping and sightseeing.

[0003] In existing car pop-up roof structures, the curtain is usually used to cover the side wall area after the pop-up roof is unfolded, serving to shield from wind and rain, protect privacy, and enhance aesthetics. Currently, when the curtain is unfolded or retracted, relative sliding and misalignment easily occur between the folded sections, resulting in uneven stacking of the curtain and twisting and deformation after unfolding, causing inconvenience in use. Therefore, how to improve the ease of use of the pop-up roof structure is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a roof assembly and a vehicle, and the roof assembly according to this application improves ease of use.

[0006] According to the roof assembly proposed in the first aspect of this application, the connecting part can guide the folding section to deform in an orderly manner along a preset path. When the roof is lowered and close to the vehicle body, the high-rigidity connecting part can maintain its shape stability and provide a folding guide for adjacent folding sections, so that the folding sections can be neatly folded together in a predetermined direction. This avoids messy stacking, twisting, jamming, or local arching of the curtain during the folding process, ensuring that the curtain folds smoothly and has a regular shape. No additional guide plate or shaping ring structure is required, which not only greatly reduces the storage volume but also simplifies the overall structure, making the roof frame design more compact. At the same time, it leaves more room for the use of interior space and improves the space utilization efficiency of the whole vehicle.

Along a first direction, the first patch and the second patch are located on the same side of the curtain. The first direction is perpendicular to the vertical direction of the vehicle.

[0010] In the above solution, the above structure can effectively avoid the folded sections from tilting disorderly to both sides, crossing and tangling or getting stuck, and further improve the ease of use.

[0011] Optionally, along the first direction, the multiple folded segments have the same size.

The second folding section is located at the bottom of the curtain and is mounted on a second fixed plate.

[0014] In the above scheme, the above structure can provide a stable installation benchmark for the unfolding and retracting of the curtain, and avoid the upper and lower ends of the curtain from becoming loose, offset or misaligned during the lifting and lowering of the top cover.

[0015] Optionally, the vehicle body has a storage slot facing the top cover, which can optionally seal the storage slot, and a second fixing plate is disposed on the bottom wall of the storage slot.

[0016] In the above solution, the structure can form a closed protection for the curtain inside the groove when it is stored, isolate it from external environmental erosion, and significantly improve the reliability of the curtain.

[0017] Optionally, both the folding section and the connecting part are constructed as ring-shaped structural components.

[0018] In the above scheme, the integrated ring structure has good formability and strong overall structure, which can further improve the overall structural strength of the curtain and eliminate defects such as local cracking and deformation.

[0019] Optionally, the folding segment includes two first segments and two second segments. The two first segments extend along the left-right direction of the vehicle and are positioned opposite each other and spaced apart along the front-back direction of the vehicle.

[0020] In the above solution, the above structure can reduce local bulges, wrinkles, skewing and jamming, and improve ease of use.

[0021] Optionally, the connecting part includes one of a thermoformed part, a mechanically indented part, and a laser-marked part.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] With the upgrading of car consumption concepts, the function of cars has shifted from a simple means of transportation to a multifunctional leisure space. SUVs and MPVs, due to their larger interior space, have become popular choices for roof extensions. Through the use of a pop-up roof structure, the vehicle can expand its vertical space while parked, providing users with diversified usage scenarios such as camping and sightseeing.

[0034] In automotive pop-up roof structures, curtains are typically used to cover the side wall areas after the roof is extended, serving to provide shelter from wind and rain, protect privacy, and enhance aesthetics. Currently, the most common methods for implementing curtains are as follows: Method 1: Flat Folding Type: This method uses multiple stacked flat panels stored along the edge of the roof, and unfolds via rails or hinges. While simple in structure, this method does not provide excellent wind and rain protection.

[0035] Method 2: One-way folding: The curtain is folded in an accordion-like manner in a single direction, forming folded sections only on one or both sides. While this method is an improvement over flat folding, it still suffers from the problem that the ends of the curtain cannot be seamlessly joined after unfolding, requiring additional seams or connectors to form a complete closure.

[0036] Method 3: Folding type with "V" guide plate: To solve the problem of disordered curtain storage, existing technologies usually set additional "V" guide plates or shaping rings on the roof frame to constrain the unfolding path of the curtain through physical limitation. Although this method can regulate the unfolding trajectory of the curtain to a certain extent, it increases the structural complexity and the number of parts.

[0037] In related technologies, curtain fabrics often employ flat stacking or unidirectional folding methods, resulting in a lack of natural guiding constraints during unfolding / retraction. When the curtain fabric is unfolded or retracted, relative sliding and misalignment easily occur between the folded sections, leading to uneven stacking and twisting deformation after unfolding. This problem is particularly pronounced when the pop-up structure is large. Related technologies commonly employ additional structures such as guide plates, steel rings, and elastic bands. However, these guiding structures introduce the following derivative problems: (1) Structural complexity: The guide plate and its shaping steel ring increase the number of parts and assembly processes, which increases manufacturing costs and assembly difficulty; (2) Space occupation: The "V" guide plate occupies the effective compression space in the Z direction and the physical space in the Y direction; (3) Risk of motion interference: The guide plate and the curtain are in contact with the seam. The curtain is prone to being pulled and damaged during frequent unfolding / retraction. Moreover, the form and position tolerance of the guide plate will directly affect the smoothness of the curtain movement; (4) Reduced reliability: The guide structure itself increases the failure point. Deformation and loosening of the guide plate will lead to abnormal movement of the curtain.

[0038] In addition, the existing ring-shaped closure of the roof-lifting curtain mainly relies on stitching, that is, setting stitching areas at the beginning and end of the curtain. This method has the following shortcomings: (1) Appearance defects: stitch marks destroy the integrity and aesthetics of the curtain surface, which is inconsistent with the high-end positioning pursued by the roof-lifting structure; (2) Sealing hazards: stitch holes are prone to seepage points under long-term rain and ultraviolet radiation, affecting waterproof performance; (3) Poor durability: the stitching area is the stress concentration area of ​​the curtain, which is prone to breakage or unraveling during frequent folding and unfolding.

[0039] In view of this, in order to improve the ease of use of the roof assembly, this application proposes a roof assembly in which the curtain includes multiple alternating folding segments and multiple connecting parts. The stiffness of the connecting parts is greater than that of the folding segments, so that when the roof is close to the vehicle body, two adjacent folding segments can close together, which greatly reduces the storage volume. No additional guide plate and shaping ring structure are required, making the roof frame design more compact. At the same time, more margin is reserved for the utilization of interior space, improving the space utilization efficiency of the whole vehicle. The folding trajectory and end constraint design of the single-layer fabric are optimized, so that the curtain can achieve stable and reliable opening and closing movement in the vertical state.

[0040] The following description, in conjunction with the accompanying drawings, describes a roof assembly and vehicle according to embodiments of this application.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, a vehicle roof assembly, including a vehicle body 100, a curtain 200, and a roof cover 300, is provided according to an embodiment of the first aspect of this application.

[0042] The top cover 300 is vertically mounted on the vehicle body 100. Along the vertical direction Z of the vehicle, one end of the curtain 200 is mounted on the top cover 300, and the other end of the curtain 200 is mounted on the vehicle body 100. The curtain 200 is adapted to be opened or closed when the top cover 300 is away from or close to the vehicle body 100. Specifically, the other end of the curtain 200 can be mounted on the side beam of the vehicle body 100. When the top cover 300 is raised, the curtain 200 can be opened by the top cover 300. The curtain 200 and the top cover 300 can jointly enclose an extended space.

[0043] The curtain 200 includes multiple alternating folded sections 210 and multiple connecting portions 220. The connecting portions 220 are more rigid than the folded sections 210, so that when the top cover 300 approaches the vehicle body 100, adjacent folded sections 210 close together. Specifically, the curtain 200 can be constructed as an accordion-shaped structure. When the top cover 300, along with one end of the curtain 200, rises, the accordion-shaped curtain 200 unfolds; when the top cover 300, along with one end of the curtain 200, descends, the accordion-shaped curtain 200 closes.

[0044] The connecting part 220 can guide the folding section 210 to deform in an orderly manner along a preset path. When the top cover 300 descends and approaches the vehicle body 100, the connecting part 220 with high rigidity can maintain its shape and provide a closing guide for the adjacent folding section 210, so that the folding section 210 can be neatly folded and closed along the predetermined direction, avoiding messy stacking, twisting and jamming or local arching of the curtain 200 during the closing process, and ensuring that the curtain 200 closes smoothly and has a regular shape.

[0045] Reduce wear and fatigue damage caused by irregular folding of the curtain 200, extend the service life of the curtain 200, and maintain good appearance flatness during the lifting and lowering of the roof 300, thereby improving the overall operational stability and reliability of the roof assembly.

[0046] In some specific embodiments, the curtain 200 uses a single layer of fabric. The single layer of fabric is folded in an accordion shape to achieve natural and orderly movement of the curtain 200 during the unfolding and folding process. No additional guide plate or shaping ring structure is required. The folding trajectory and end constraint design of the single layer of fabric are optimized to enable the curtain 200 to achieve stable and reliable opening and closing movement in a vertically continuous state.

[0047] In some specific embodiments, the multiple connecting portions 220 include multiple first connecting portions 221 and multiple second connecting portions 222, the multiple folding segments 210 include multiple first folding segments 211 and multiple second folding segments 212, the curtain 200 includes multiple folding units connected sequentially along the vertical direction Z of the vehicle, and two adjacent folding units are connected by the first connecting portion 221. Each folding unit includes a first folding segment 211, a second connecting portion 222 and a second folding segment 212 connected sequentially.

[0048] Along the vertical direction Z of the vehicle, one end of the first folding segment 211 is connected to a first connecting part 221, the other end of the first folding segment 211 is connected to one end of a second connecting part 222, the other end of the second connecting part 222 is connected to one end of a second folding segment 212, and the other end of the second folding segment 212 is connected to one end of another first connecting part 221. When the top cover 300 is close to the vehicle body 100, any two adjacent folding units close together, and the first folding segment 211 and the second folding segment 212 of each folding unit close together.

[0049] The first connecting part 221 and the second connecting part 222 can be formed by hot pressing.

[0050] Furthermore, along the first direction A, the cross-sectional shape of the curtain 200 is a zigzag shape, the cross-sectional shape of the folded section 210 is a zigzag segment, and the cross-sectional shape of the connecting part 220 is a zigzag endpoint.

[0051] In some embodiments, the folding section 210 and the connecting part 220 are made of the same material. That is, the curtain 200 is constructed as a one-piece molded part, which simplifies the production process, reduces manufacturing costs, avoids the risk of delamination and cracking caused by bonding different materials, and improves the overall structural strength and service life of the curtain 200. On the other hand, the same material can ensure that the coefficient of thermal expansion is consistent, and there will be no uneven deformation due to material differences in high and low temperature environments. This ensures that the curtain 200 can still be neatly folded along the preset trajectory when the top cover 300 is raised and lowered, improving working stability and environmental adaptability.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the curtain 200 also includes a first patch 230 and a second patch 240. Along the vertical direction Z of the vehicle, the first patch 230 and the second patch 240 are respectively disposed on the side of two adjacent folding sections 210 facing each other. Along the first direction A, the first patch 230 and the second patch 240 are located on the same side of the curtain 200. The first direction A is perpendicular to the vertical direction Z of the vehicle.

[0053] By utilizing the contact guidance, magnetic attraction, or adhesion between the two patches, adjacent folding sections 210 are forced to fold and align orderly to the same side, effectively preventing the folding sections 210 from tilting disorderly to both sides, crossing, or getting stuck. At the same time, the first patch 230 and the second patch 240 can locally reinforce the bending area of ​​the folding section 210, reducing stress concentration and fatigue damage caused by repeated folding, and improving the durability of the curtain 200; moreover, the structural design of arranging them on the same side is simple, does not increase the overall thickness of the curtain 200, ensures a flat and compact shape after folding, and does not interfere with the normal lifting and lowering of the top cover 300.

[0054] Specifically, the first patch 230 and the second patch 240 can be applied together to the inside of the curtain 200 or together to the outside of the curtain 200. The first direction A can be the vehicle's front-to-back direction X or left-to-right direction Y.

[0055] In some embodiments, the multiple folding segments 210 are of the same size along the first direction A. This ensures that the curtain 200 is subjected to uniform force during unfolding and retraction, guaranteeing that each folding segment 210 folds synchronously and stacks neatly, avoiding localized arching, uneven stretching, or jamming due to size differences. Simultaneously, uniform dimensions facilitate the one-piece processing of the curtain 200, simplifying production and assembly processes, and also resulting in a more regular and flat shape after the curtain 200 is retracted, improving the appearance consistency and operational stability of the roof assembly.

[0056] In some embodiments, such as 1, Figure 2 and Figure 3 As shown, the roof assembly also includes a first fixing plate 400 and a second fixing plate 500, the first fixing plate 400 being fixed to the roof 300 and the second fixing plate 500 being fixed to the vehicle body 100. Along the vertical direction Z of the vehicle, multiple folding sections 210 include a first folding section 211 and a second folding section 212. The first folding section 211 is located at the uppermost end of the curtain 200 and is disposed on the first fixing plate 400. The second folding section 212 is located at the lowermost end of the curtain 200 and is disposed on the second fixing plate 500.

[0057] It can achieve precise positioning and secure fixation of the upper and lower ends of the curtain 200. This structure can provide a stable installation benchmark for the unfolding and closing of the curtain 200, and prevent the upper and lower ends of the curtain 200 from becoming loose, offset or displaced during the lifting and lowering of the top cover 300, ensuring that the curtain 200 as a whole follows the top cover 300 to make regular telescopic and folding movements.

[0058] Meanwhile, the fixing plate provides structural protection and rigid support to both ends of the curtain fabric 200, dispersing the tensile stress at the ends during folding and preventing cracking, peeling, wear, and aging at the ends of the curtain fabric 200 due to long-term stress, effectively extending the service life of the curtain fabric 200. This significantly improves the stability and reliability of the roof assembly during operation.

[0059] In some embodiments, such as Figure 1 As shown, the vehicle body 100 has a storage groove 110 facing the roof 300. The roof 300 can optionally seal the storage groove 110, and a second fixing plate 500 is disposed on the bottom wall of the storage groove 110. This provides a completely enclosed protection and neat storage for the lower storage area of ​​the curtain 200. When the roof 300 is lowered and retracted, the curtain 200 can be completely stored inside the storage groove 110, preventing the lower end of the curtain 200 from being exposed, piled up, or warped, significantly improving the overall flatness and appearance of the roof after it is retracted.

[0060] The storage slot 110 can provide circumferential restriction and protection for the bottom of the curtain 200, effectively reducing wind disturbance, sand, rain and dust directly washing and abrading the lower fixed position of the curtain 200 during driving, and reducing problems such as aging, loosening and wear at the base of the curtain 200.

[0061] Meanwhile, the second fixing plate 500 is embedded in the storage slot 110, which does not occupy external assembly space. The structure layout is more compact, which can avoid the abruptness of the exposed installation structure and prevent the fixing structure from interfering with the surrounding vehicle body 100 parts. This further ensures the smoothness and stability of the lifting of the top cover 300 and the folding and closing of the curtain 200.

[0062] In some embodiments, both the folding segment 210 and the connecting portion 220 are constructed as annular structural components. This effectively alleviates local fatigue damage caused by bending and pulling, significantly improving the overall bending resistance and service life of the curtain fabric 200. Simultaneously, the annular structure exhibits high regularity, with uniform circumferential deformation during folding and closing. This, combined with the guiding effect of the rigid connecting portion 220, allows each folding segment 210 to uniformly close and stack neatly layer by layer along the annular circumference, completely avoiding local wrinkles, twisting, misalignment, or jamming problems, ensuring the stability and consistency of the curtain fabric 200's folding movement.

[0063] In a specific embodiment, the first fixing plate 400 and the second fixing plate 500 are also constructed as ring-shaped structural components.

[0064] In some embodiments, such as Figure 4 As shown, the folding section 210 includes two first sections 210a and two second sections 210b. The two first sections 210a extend along the left-right direction Y of the vehicle and along the front-back direction X of the vehicle. The two first sections 210a are opposite to each other and spaced apart. The two second sections 210b extend along the front-back direction X of the vehicle and along the left-right direction Y of the vehicle. The two second sections 210b are opposite to each other and spaced apart.

[0065] Specifically, a connecting section is provided between the first section 210a and the second section 210b, and they are connected as one piece using an integrated connection process (hot melt welding or adhesive bonding), which eliminates the appearance defects and sealing hazards caused by stitching, and achieves the overall integrity and high-end feel of the top curtain fabric 200.

[0066] (1) Hot melt welding: An overlap area is set at the beginning and end of the curtain 200, and the two sections of curtain 200 are fused together by high-frequency hot pressing or ultrasonic welding to form a seamless connection.

[0067] (2) Adhesive sealing: Apply a special flexible adhesive to the overlapping area, press and cure to form a strong and flexible connection.

[0068] Specifically, when the curtain 200 is unfolded, it is in the shape of an approximately rectangular sheet, and the edges on its left and right sides are connected to each other through the end connection structure to form a racetrack-shaped or ring-shaped closed outline.

[0069] During the lifting and lowering of the top cover 300, the folding deformation of the curtain 200 in the front, back, left, and right directions is matched and synchronized, effectively solving the problem of uneven deformation and unilateral pulling of the curtain 200. The regular four-sided segmented structure can constrain the folding trajectory of the curtain 200, and together with the guiding and positioning function of the connecting part 220, it ensures that each side can be bent evenly and aligned, reducing local bulges, wrinkles, skewing, and jamming.

[0070] In some embodiments, the connecting portion 220 includes one of a thermoformed part, a mechanically indented part, and a laser-marked part. That is, the accordion fold of the curtain fabric 200 body can be achieved by thermoforming, mechanical indentation, or laser marking. After folding, the curtain fabric 200 maintains a corrugated shape in its natural state. When an upward unfolding force is applied, the folded sections 210 unfold sequentially, and when a downward retraction pressure is applied, the folded sections 210 retract sequentially.

[0071] Without altering the material of the fabric 200 substrate, a folding guide structure with higher rigidity and a fixed trajectory can be precisely molded, achieving precise shaping of the accordion-style folding of the fabric 200. The connecting part 220, processed through the above process, can pre-set a fixed folding trajectory for the fabric 200, ensuring that the fabric 200 maintains a stable and regular corrugated shape in its natural state, preventing arbitrary deformation, loosening, or collapse.

[0072] During the lifting and lowering of the top cover 300, when an upward unfolding force is applied, each folding section 210 can unfold smoothly along a preset trajectory, with a smooth unfolding process without jamming or twisting; when a downward retraction pressure is applied, the folding sections 210 can close and retract in an orderly manner, with highly uniform and controllable folding actions.

[0073] This structure solves the problems of disordered folding and chaotic positioning of traditional flexible curtain 200 through process standardization, greatly improving the consistency and stability of the curtain 200's unfolding and retraction. At the same time, the standardized folding structure has stronger fatigue resistance and can adapt to the long-term frequent lifting and lowering conditions of the roof 300, effectively extending the service life of the curtain 200 and ensuring the long-term stable operation of the roof components.

[0074] Secondly, embodiments of this application provide a vehicle including the roof assembly described in any of the above claims.

[0075] The vehicle according to the second aspect of this application improves usability by including the roof assembly described in any of the foregoing claims.
