Description

Technical Field

[0001] The utility model relates to a non-fixed vehicle roof, and particularly to a liftable sunshade assembly. Background Art

[0002] In the existing panoramic sunroof assembly solutions, one is a sunroof curtain completely fixed on the vehicle roof frame, and the other is an openable sunroof. In this technical solution, the rear glass panel is fixed, and the front glass panel slides above the rear glass along with the mechanical group under the drive of the motor and the flexible shaft to realize the opening of the sunroof.

[0003] The existing vehicle sunroof wind deflector is a device installed on the vehicle sunroof. When the sunroof is opened while the vehicle is running, the wind deflector automatically pops up upward to reduce wind noise and the impact of air flow on the passengers in the vehicle, and at the same time ensure the air circulation in the vehicle. The existing wind deflectors are usually made of a single flexible material. For example, the "low wind noise self-locking wind deflector" disclosed in the invention patent application with the publication number CN118322816A adopts a pair of mutually hinged and foldable frame structures, and a flexible mesh material is fixed inside the frame structure. When the sunroof is closed, the top frame is pressed down to close the mesh cloth, and when the sunroof is opened, the top frame pops up upward under the action of elastic force to open the mesh cloth.

[0004] It can be expected that since the area of the mesh cloth in this solution is small, even if it falls and accumulates in a disorderly manner, its accumulated volume will not be greater than the volume of the folded frame. Therefore, there is no need to consider its interference with the sunroof mechanical group or the glass panel during the working process. However, when a wind deflector with a larger unfolded area or a nylon material with a higher hardness is used, since the stacking volume increases exponentially, if it is not folded along the regular preset path, it will inevitably cause great obstacles to the operation of the sunroof assembly. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a liftable sunshade assembly, which fundamentally solves the above problems and can realize the orderly folding of a large-area tarpaulin through a simple splicing method of common materials.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: The liftable sunshade assembly includes a seat frame assembly, a pair of mechanical group assemblies, and a tarpaulin assembly. The technical key points are as follows:

[0007] The seat frame assembly includes a pair of parallel guide rail assemblies arranged along the vehicle forward direction, a rear seat frame assembly and a front seat frame assembly fixed at the front and rear ends of the guide rail assembly;

[0008] The mechanical assembly includes a hinge assembly fixed to the front end of the guide rail assembly, a strut bracket slidably limited within the guide rail assembly, a glass mounting bracket fixed to one end of the hinge assembly, an electric strut hinged between the glass mounting bracket and the strut bracket, and a plurality of self - suction locks fixed along the direction of the guide rail assembly;

[0009] The hinge assembly includes a lower connecting rod, an upper bracket, a first connecting portion, and a second connecting portion that are sequentially connected and fixed to the front end of the guide rail assembly at the bottom, forming an unequal - length double - crank mechanism. The same - side ends of the lower connecting rod and the upper bracket extend towards the same outer side of the quadrilateral. The glass mounting bracket is fixed to the upper bracket; when the upper bracket moves downward to the first use state, the inner end of the upper bracket inclines downward, the middle end of the upper bracket abuts against the bottom surface of the lower connecting rod, and the outer end is parallel to the lower connecting rod; when the upper bracket moves upward to the second use state, the upper bracket inclines upward, so that the maximum included angle is formed between the upper bracket or the glass mounting bracket and the lower connecting rod.

[0010] Furthermore, the awning assembly includes an awning upper bracket, an awning lower bracket, and a foldable U - shaped awning embedded therein; the U - shaped awning includes a plurality of spaced - apart pleated portions and crease portions, and the pleated portions and the crease portions are fixed by the side edges; under the guidance of the crease portions, adjacent pleated portions are folded in an overlapping manner.

[0011] Furthermore, strip - shaped card slots are respectively provided at the ends of the awning upper bracket and the awning lower bracket. Both ends of the U - shaped awning are closed by an upper insert strip and the U - shaped awning respectively, and can be foldably fitted into the strip - shaped card slots of the awning upper bracket and the awning lower bracket through the upper insert strip and the U - shaped awning respectively.

[0012] Furthermore, when the hardness of the pleated portion is greater than that of the crease portion, the pleated portion gradually accumulates from bottom to top under the guidance of its own weight; when the hardness of the pleated portion is less than that of the crease portion, the pleated portion folds towards the crease portion under the prestress guidance of the crease portion.

[0013] Furthermore, when the U - shaped awning is folded, the crease portions guide the pleated portions in an alternating left - right manner.

[0014] Furthermore, the U - shaped awning includes a front - folding awning unit and a pair of symmetrically arranged side - folding awning units; the side - folding awning units are matched with the front - folding awning unit in a way of bending inward and extending, so as to fold in a way that the bending parts overlap each other.

[0015] The beneficial effects of the present utility model: In the overall technical solution, the skylight assembly uses a pair of electric struts as the driving power, cooperates with the strut bracket to slide within the guide rail assembly, enables the glass mounting bracket to swing upward or downward with the hinge assembly as the center, and further realizes the opening or closing of the roof or the awning. At the same time, the strut bracket cooperates with the self - suction lock within the guide rail to realize the opening of the glass assembly at different preset angles.

[0016] Specifically, for the tarpaulin assembly, since the pleated part and the crease part are made of elastic materials with different hardness or flexibility, the pleated part can always be folded and stored in the seat frame assembly according to the preset crease part under the guiding action of the crease part. Thus, it avoids the situation in the prior art where when a large-area tarpaulin is stacked downward disorderly, it accumulates on the mechanical group assembly and the guide rail assembly, hindering the smooth operation of the glass assembly.

[0017] The sunshade curtain assembly adopts a similar method to the prior art. The motor drives the crossbeam to slide along the guide rail direction through a flexible shaft and a slider, guiding the unfolding or retracting of the curtain cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following Figures 1 - 4 is a detailed description of the specific content of the present utility model through specific embodiments. Embodiment 1

[0026] The liftable sky curtain assembly includes a glass assembly 1, a seat frame assembly 2, a pair of mechanical group assemblies 3, a tarpaulin assembly 4, and a sunshade curtain assembly 5. The following describes the specific structures and working principles of each component in sequence according to the drawings.

[0027] As Figure 1a , Figure 2As shown in the figure, the sunshade curtain assembly 5 is limited on the seat frame assembly 2, specifically including a motor 55 arranged in the front seat frame assembly 23, a rotating shaft assembly 52 rotatably limited in the guide rail assembly 22, a support rod assembly 53 supported between the guide rail assemblies 22, a pair of sliders 54 slidably limited in the guide rail assembly 22, a cross beam 51 fixed between the sliders 54 for guiding the movement of the curtain cloth 56, and a flexible shaft 58 connected between the motor 55 and the slider 54. At the same time, to ensure the sealing performance of the outer edge of the roof when it is closed, a sealing strip 14 is also provided between the guide rail assembly 22 and the glass assembly 1. To prevent the glass assembly 1 from rubbing against the inner side of the guide rail assembly 22 when it is closed, a buffer rubber strip (not marked in the figure) is also provided on the inner side of the guide rail assembly 22. The flexible shaft is slidably limited in the flexible shaft chute preset in the front seat frame assembly 23, the guide rail assembly 22, and the rear seat frame assembly 21. One end is driven by the motor 55, and the other end is fixed to the slider 54. Thus, the slider 54 can be driven to slide along the guide rail assembly 22 by controlling the motor 55 and the flexible shaft. Both sides of the curtain cloth 56 are fixed on the curtain cloth clamping strip 57 and are clamped in the chute on the inner side of the guide rail assembly 22, thereby driving the unfolding or retraction of the curtain cloth 56.

[0028] As Figure 2 shown in the figure, the glass assembly 1 includes a glass insert 12 fixed to the top of the vehicle through PU13 and a laminated glass 11 fixed to the glass insert 12 through an adhesive.

[0029] As Figure 2 shown in the figure, the seat frame assembly 2 includes a pair of guide rail assemblies 22 fixed between the front seat frame assembly 23 and the rear seat frame assembly 21, and an ECU assembly 24 respectively arranged on the front seat frame assembly 23 or the rear seat frame assembly 21. The ECU assembly 24 is connected to the motor 56, the electric strut 33, the self-locking lock 35 and other electronic control components through the wire harness assembly located in the seat frame assembly 2, so as to control the actions of the corresponding assemblies by triggering a preset program.

[0030] As Figure 1b shown in the figure, the guide rail assembly 22 includes an outer rib plate for fixing the roof frame, a U-shaped track part in the middle, and a sunshade curtain chute part on the inner side for cooperating with the stretching of the curtain cloth. The U-shaped track also includes outer chutes for cooperating with the mechanical group, which are parallel and spaced from each other, and an inner chute for fixing the U-shaped awning cloth 43.

[0031] As Figure 2As shown in the figure, the mechanical assembly 3 includes a hinge assembly 31 fixed to the front end of the guide rail assembly 22, a strut bracket 34 slidably limited within the guide rail assembly 22, a glass mounting bracket 32 fixed at one end to the hinge assembly 31, an electric strut 33 hinged between the glass mounting bracket 32 and the strut bracket 34, and a self-locking lock 35 installed within the guide rail assembly 22 for locking the sliding position of the strut bracket 34. The electric strut 33 is extended by the vehicle electronic control assembly, thereby adjusting the opening degree of the glass mounting bracket 32 and locking and positioning it at the corresponding position through the strut bracket 34. Specifically, when the roof is closed, the strut bracket 34 slides backward along the guide rail assembly 22 to the self-locking lock 35 at the end; when the roof is opened, according to the opening angle, the strut bracket 34 slides forward along the guide rail assembly 22 to the self-locking lock 35 at the corresponding position. In this embodiment, three sets of self-locking locks 35 are taken as an example, and the actual number can be increased or decreased according to specific customization requirements.

[0032] As Figure 3 shown in the figure, the hinge assembly 31 includes a lower connecting rod 311, an upper bracket 312, a first connecting portion 313, and a second connecting portion 314 that are sequentially connected and fixed to the front end of the guide rail assembly 22 at the bottom; thus, four connection points form a non-equilateral double-crank mechanism, and the same-side ends of the lower connecting rod 311 and the upper bracket 312 extend to the same outer side of the quadrilateral, so that when the upper bracket 312 moves downward to the first use state when the roof is closed, that is Figure 3 in the state, the inner end of the upper bracket 312 inclines downward, the middle end of the upper bracket 312 abuts against the bottom surface of the lower connecting rod 311, and the outer end is parallel to the lower connecting rod 311; when the upper bracket 312 moves upward to the second use state when the roof is opened (figure omitted), the upper bracket 312 inclines upward, causing the quadrilateral to swing to the preset position at the outer side end. At this time, the maximum included angle is formed between the upper bracket 312 and the lower connecting rod 311. As is known to those skilled in the art, usually, to reduce wind resistance and wind noise during driving, the tarpaulin assembly 4 unfolds at the rear side. If the use environment is designed to be opened in a non-driving state, the tarpaulin assembly 4 can also unfold at the front side (figure omitted). To facilitate the installation of the glass assembly 1, the glass mounting bracket 32 for fixing the glass insert 12 is fixed to the outer end of the upper bracket 312.

[0033] As Figure 1a 、 Figure 1b 、 Figure 1c 、 Figure 4As shown, the U-shaped tarpaulin 43 is foldably fitted between two sets of annular support assemblies. According to the conventional design in the art, an integrally formed annular support assembly is preferably used. However, to avoid interference with the sunshade curtain assembly 5, it is designed as a split structure. For example, in this embodiment, the upper support assembly, i.e., the tarpaulin upper support 44 which is an independent annular shape, is fixed below the glass assembly 1, and the lower support assembly is designed as a split structure. Specifically, it includes a pair of tarpaulin side supports 45, a tarpaulin front support 48 and a tarpaulin rear support 49 located therebetween, a rear corner support 46 as a transition section between the tarpaulin side support 45 and the tarpaulin front support 48, and a front corner support 47 as a transition section between the tarpaulin side support 45 and the tarpaulin front support 48. When transitioning from the tarpaulin side support 45 to the tarpaulin rear support 49, the height gradually rises, that is, the horizontal plane where the tarpaulin rear support 49 is located is higher than the horizontal plane where the tarpaulin side support 45 is located, so as to avoid blocking the normal unfolding of the curtain of the sunshade curtain assembly 5.

[0034] In addition, Figure 4 the vertical texture on the U-shaped tarpaulin 43 is only the residue of the structure line generated during the CAD modeling process, which does not represent any technical features in the technical solution and is not used to limit the protection scope of the present utility model. Embodiment 2

[0035] The U-shaped tarpaulin 43 of the present utility model can further adopt the following scheme, so that it can be completely stored in a preset manner when folded, avoiding the situation that the roof cannot be normally closed or the sunshade curtain cannot be retracted due to random folding in a disorderly manner.

[0036] The U-shaped tarpaulin 43 includes a front folding tarpaulin unit and two side folding tarpaulin units. The folding tarpaulin unit includes a plurality of pleat portions 431 made of a first material and arranged at intervals in a first direction and extending in a second direction, and pleat portions 431 made of a second material. The adjacent pleat portions 431 and crease portions 432 are fixed in the second direction by bonding or sewing. The two outermost ends of the U-shaped tarpaulin 43 adopt pleat portions 431. Preferably, the tarpaulin lower insert strip 41 and the tarpaulin upper insert strip 42 are fixed in the pleat portions 431 by bonding or sewing.

[0037] Among them, in the front folding tarp unit, the first direction generally refers to the vehicle height direction, and the second direction generally refers to the vehicle horizontal direction; in the side folding tarp unit, the first direction generally refers to the vehicle height direction, and the second direction generally refers to the vehicle length direction. Due to the folding, storage, and unfolding of the tarp assembly 4 during use, the non-standard shapes of the pleat portions 431 and the crease portions 432, the fact that the unfolding angle at the front side of the tarp assembly 4 is greater than that at the rear side, and the elasticity of the material of the tarp assembly 4 itself, when describing the direction of the tarp assembly 4, it does not refer to a unique direction positioning, but rather a set of trends of several scattered directions along a specific direction. That is, the first direction or the second direction mentioned in the text does not refer to the orthogonal directions of the height, width, and length of the vehicle coordinate system, but rather a set of action trends.

[0038] As Figure 1b shown, when the roof is opened, the glass assembly 1 is driven by the tarp upper bracket 44 to move upward along an arc, and the upper insert strip 42 embedded therein sequentially pulls the pleat portion 431, the adjacent crease portion 432, the adjacent pleat portion 431, and so on, until the hinge assembly 31 reaches the maximum unfolding angle and the glass assembly 1 is fully opened.

[0039] As Figure 1c shown, when the roof is closed, if the hardness of the pleat portion 431 is greater than that of the crease portion 432, for example, both the pleat portion 431 and the crease portion 432 are made of nylon cloth with a waterproof coating, and the material thickness of the pleat portion 431 is greater than that of the crease portion 432, the hardness distinction can be achieved, then the pleat portion 431 gradually accumulates from bottom to top under the guidance of its own weight until the glass assembly 1 is fully closed.

[0040] When the hardness of the pleat portion 431 is less than that of the crease portion 432, for example, the pleat portion 431 is made of a flexible material with a relatively light weight, such as a mesh cloth, it is difficult to fold in a preset manner, so it is usually stored by means of winding. To ensure normal folding and use, the crease portion 432 is made of prefabricated V-shaped creases of TPU, TPE, etc. When the glass assembly 1 closes downward, the relatively light pleat portion 431 folds and accumulates towards the crease portion 432 under the guidance of the prestressed elastic force of the crease portion 432. The bottom stacking unit with a relatively large mass falls back to the guide rail assembly 22 under the guidance of its own weight, and the relatively light pleat portion 431 at the upper part continues to fold and accumulate towards the crease portion 432 under the guidance of the crease portion 432 until the glass assembly 1 is fully closed, thus avoiding the chaotic storage of the U-shaped tarp 43 during the closing process of the glass assembly 1. Embodiment 3

[0041] When the design purpose is a roof tent that can be deployed when the vehicle is not in motion, the extension distance of the strut bracket 34 can be further increased, and at the same time, the stroke of the strut bracket 34 can be adjusted accordingly, so that on the basis of Embodiment 1 or Embodiment 2, the headroom when the awning is opened can be further increased, so as to be used as a roof tent, and its storage is extremely simple and convenient, without the need to purchase an additional tent fixed on the roof of the vehicle. Embodiment 4

[0042] When the design purpose is a roof tent that can be deployed when the vehicle is not in motion, a pair of electric struts 33 can also be added at the front, so as to further increase the headroom when the awning is opened.
