Description

Technical Field

[0001] The utility model relates to a component of an automobile sunroof, and particularly relates to a folding tarpaulin for a roof lifting system. Background Art

[0002] In the existing panoramic sunroof assembly solutions, one is a roof sky curtain completely fixed on the automobile roof frame, and the other is an openable roof. 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 windscreen is a device installed on the automobile sunroof. When the sunroof is opened during vehicle driving, the windscreen automatically pops up upward to reduce wind noise and the influence of air flow on the passengers in the vehicle, and at the same time ensure the air circulation in the vehicle. The existing windscreen is usually made of a single flexible material. For example, the "low wind noise self-locking windscreen" disclosed in the invention patent application with the publication number CN118322816A adopts a pair of foldable skeleton structures hinged to each other, and a flexible mesh material is fixed inside the skeleton structure. When the sunroof is closed, the top skeleton is pressed down to close the mesh cloth, and when the sunroof is opened, the top skeleton 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 skeleton. Therefore, there is no need to consider its interference with the operation of the sunroof mechanical group or the glass panel. However, when a mesh cloth structure with a larger unfolded area is adopted, or a nylon material with a higher hardness is used, since the stacking volume increases exponentially, if it is not folded according to the regular preset path, it will surely cause great hindrance to the operation of the sunroof assembly. Content of the Utility Model

[0005] The purpose of the utility model is to provide a folding tarpaulin for a roof lifting system, 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 solution: the folding tarpaulin for the roof lifting system includes more than one folding tarpaulin unit arranged along the roof opening, and the technical key points are: the folding tarpaulin unit includes a plurality of spaced-apart pleated parts and crease parts, and the pleated parts and the crease parts are fixed by the side edges;

[0007] On the pleated part at the end, a strip is fixed along its edge;

[0008] Under the guidance of the crease part, adjacent pleated parts are folded in an overlapping manner, and the crease part guides the pleated parts in an alternating left and right manner to realize regular and orderly folding;

[0009] There are three folding tarp units, one front folding tarp unit and a pair of symmetrically arranged side folding tarp units.

[0010] Furthermore, the side folding tarp units cooperate with the front folding tarp unit in a way that extends inwardly and bends, and are folded in a way that the bent parts overlap each other.

[0011] Furthermore, the corrugated part and the crease part are made of the same material but have different thicknesses.

[0012] Furthermore, the corrugated part and the crease part have different hardnesses.

[0013] Furthermore, when the hardness of the corrugated part is greater than that of the crease part, the corrugated part gradually accumulates from bottom to top under the guidance of its own weight.

[0014] Furthermore, when the hardness of the corrugated part is less than that of the crease part, the corrugated part folds towards the crease part under the guidance of the prestress of the crease part.

[0015] The beneficial effects of the present utility model: In the overall technical solution, the sunroof assembly uses a pair of electric struts as the driving power to cooperate with the strut brackets to slide within the guide rail assembly, causing the glass mounting bracket to swing upward or downward with the hinge assembly as the center, thereby realizing the opening or closing of the roof or tarp. At the same time, the strut brackets cooperate with the self - absorbing locks within the guide rails to enable the glass assembly to be opened at different preset angles.

[0016] In terms of the specific structure, for the tarp assembly, since the corrugated part and the crease part adopt elastic materials with different hardnesses or flexibilities, the corrugated part can always be folded and stored within the seat frame assembly under the guiding action of the crease part. Thus, it avoids the situation in the prior art where a large - area tarp stacks downward disorderly and accumulates on the mechanical assembly and the guide rail assembly, hindering the smooth operation of the glass assembly.

[0017] The sunshade curtain assembly adopts a method similar to the prior art, where the motor drives the cross - beam 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 combines Figures 1 - 4 , and details the specific content of the present utility model through specific embodiments. Embodiment 1

[0026] The liftable awning 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 specific structures and working principles of each component are described below in the order of the drawings.

[0027] As Figure 1a , Figure 2 shown, the sunshade curtain assembly 5 is limited on the seat frame assembly 2, and specifically includes 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, in order to ensure the sealing performance of the outer edge of the awning when it is closed, a sealing strip 14 is also provided between the guide rail assembly 22 and the glass assembly 1. In order 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, driven by the motor 55 at one end and fixed to the slider 54 at the other end, so that 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 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, 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 2As 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 ECU assemblies 24 separately provided on the front seat frame assembly 23 or the rear seat frame assembly 21. The ECU assemblies 24 are connected to electric control components such as the motor 56, the electric strut 33, and the self-locking suction lock 35 through a wire harness assembly located inside 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, the guide rail assembly 22 includes an outer rib plate for fixing the roof frame, a U-shaped track portion in the middle, and a sunshade chute portion on the inner side for cooperating with the curtain to stretch. The U-shaped track further includes outer slides parallel and spaced from each other for cooperating with the mechanical group, and inner slides for fixing the U-shaped tarpaulin 43.

[0031] As Figure 2 shown, the mechanical group assembly 3 includes a hinge assembly 31 fixed at 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 suction lock 35 installed within the guide rail assembly 22 for locking the sliding position of the strut bracket 34. By controlling the extension of the electric strut 33 through the vehicle electric control assembly, the opening degree of the glass mounting bracket 32 is adjusted, and the position is locked and positioned 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 suction lock 35 at the end; when the roof is opened, according to the size of the opening angle, the strut bracket 34 slides forward along the guide rail assembly 22 from the rear to the self-locking suction lock 35 at the corresponding position. In this embodiment, three sets of self-locking suction locks 35 are taken as an example, and the actual number can be increased or decreased according to specific customization.

[0032] As Figure 3 shown, 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 and the roof is closed, that is Figure 3In the first 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, the canopy is opened (figure omitted), the upper bracket 312 inclines upward, causing the quadrilateral to swing outward to a preset position. 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, generally, to reduce wind resistance and wind noise during driving, the tarp assembly 4 unfolds at the rear side. If the use environment is designed to be opened in a non-driving state, the tarp 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 4 shown, the U-shaped tarp 43 is foldably fitted between two sets of annular bracket assemblies. According to the conventional design in the art, it is preferably an integrally formed annular bracket assembly. However, to avoid interference with the sunshade curtain assembly 5, it is designed as a split structure. For example, in this embodiment, the upper bracket assembly is a tarp upper bracket 44 that is an independent ring and is fixed below the glass assembly 1, and the lower bracket assembly is designed as a split structure. Specifically, it includes a pair of tarp side brackets 45, a tarp front bracket 48 and a tarp rear bracket 49 located therebetween, a rear corner bracket 46 as a transition section between the tarp side bracket 45 and the tarp front bracket 48, and a front corner bracket 47 as a transition section between the tarp side bracket 45 and the tarp front bracket 48. When transitioning from the tarp side bracket 45 to the tarp rear bracket 49, the height gradually rises, that is, the horizontal plane where the tarp rear bracket 49 is located is higher than the horizontal plane where the tarp side bracket 45 is located, thus avoiding 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 tarp 43 in [] is only the residue of the structural line generated during the CAD modeling process, and does not represent any technical features in the technical solution, nor is it used to limit the protection scope of the present utility model. Embodiment 2

[0035] The U-shaped tarp 43 of the present utility model can further adopt the following solution, so that it can be completely stored in a preset manner when folded, avoiding the situation that the canopy 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 number of pleated portions 431 made of a first material and pleated portions 431 made of a second material that are arranged at intervals in a first direction and extend in a second direction. The adjacent pleated portions 431 and crease portions 432 are fixed in the second direction by bonding or stitching. The two outermost ends of the U-shaped tarpaulin 43 adopt the pleated portions 431. Preferably, the lower trim 41 of the tarpaulin and the upper trim 42 of the tarpaulin are fixed in the pleated portion 431 by bonding or stitching.

[0037] Among them, in the front folding tarpaulin 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 tarpaulin 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 tarpaulin assembly 4 during use, the non-standard shapes of the respective pleated portions 431 and crease portions 432, the unfolding angle of the front side of the tarpaulin assembly 4 being greater than that of the rear side, and the elasticity of the material of the tarpaulin assembly 4 itself, when describing the direction of the tarpaulin assembly 4, it does not refer to a unique direction positioning, but a set of trends of a number of scattering 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 a set of action trends.

[0038] As Figure 1b shown, when the roof is opened, the glass assembly 1 drives the upper trim 42 embedded therein to move upward along an arc through the upper tarpaulin bracket 44. The upper trim 42 sequentially pulls the pleated portion 431, the adjacent crease portion 432, the adjacent pleated 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 pleated portion 431 is greater than that of the crease portion 432, for example, both the pleated portion 431 and the crease portion 432 adopt nylon cloth with a waterproof coating and the material thickness of the pleated portion 431 is made greater than that of the crease portion 432 to achieve hardness differentiation, then the pleated 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 folded part 431 is less than that of the crease part 432, for example, when the folded part 431 is made of a lightweight flexible material such as mesh fabric, it is difficult to fold it in a preset manner. Therefore, it is usually stored by winding. To ensure normal folding and use, the crease part 432 is made of prefabricated V-shaped creased TPU, TPE, etc. When the glass assembly 1 is closed downward, the lightweight folded part 431 folds and accumulates towards the crease part 432 under the guidance of the prestressed elastic force of the crease part 432. The stacked units with a larger mass at the bottom fall back to the guide rail assembly 22 under the action of their own weight, and the lightweight folded part 431 at the upper part continues to fold and accumulate towards the crease part 432 under the guidance of the crease part 432 until the glass assembly 1 is completely closed, thus avoiding the messy storage of the U-shaped tarpaulin 43 during the closing process of the glass assembly 1. Embodiment 3

[0041] When the designed use is a roof tent that can be unfolded in a non-driving state, 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. Based on Embodiment 1 or Embodiment 2, the headroom when the roof is opened can be further increased, so that it can be used as a roof tent, and its use, 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 designed use is a roof tent that can be unfolded in a non-driving state, a pair of electric struts 33 can also be added at the front to further increase the headroom when the roof is opened.
