Description

Technical Field

[0001] The invention relates to components of a car skylight, in particular to a folding tarpaulin used in a roof lifting system. Background Art

[0002] Among the existing panoramic sunroof assembly solutions, one is a canopy that is completely fixed on the car roof frame, and the other is an openable canopy. In this technical solution, the rear glass panel is fixed, and the front glass panel is driven by a motor and a flexible shaft to slide with the mechanical group to the top of the rear glass to open the sunroof.

[0003] The existing vehicle sunroof windshield is a device installed on the sunroof of a car. When the sunroof is opened while the vehicle is driving, the windshield automatically pops up to reduce the impact of wind noise and airflow on passengers in the car, while ensuring air circulation in the car. The existing windshield is usually made of a single flexible material, such as the "low wind noise self-locking windshield" disclosed in the invention patent application with publication number CN118322816A, which adopts a pair of mutually hinged foldable skeleton structures, and a flexible mesh material is fixed in 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 under the action of elastic force to open the mesh cloth.

[0004] As can be expected, since the mesh area in this solution is small, even if it falls and piles up in a disorderly manner, its stacking volume will not be greater than the volume of the folded frame, so there is no need to consider its interference with the sunroof mechanical assembly or glass panel during operation. However, when a mesh structure with a larger unfolding area is used, or a nylon material with higher hardness is used, since the stacking volume increases exponentially, if it is not folded according to the regular preset path, it will inevitably cause great obstacles to the operation of the sunroof assembly. Summary of the invention

[0005] The purpose of the present invention is to provide a folding tarpaulin for a roof lifting system, which fundamentally solves the above-mentioned problem and can realize orderly folding of a large-area tarpaulin by a simple splicing method of common materials.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: the folding tarpaulin used in 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 pleated parts and creased parts arranged at intervals, and the pleated parts and creased parts are fixed by side edges; Under the guidance of the crease portion, adjacent pleats are folded in a manner of overlapping each other.

[0007] Furthermore, there are three folding tarpaulin units, a front folding tarpaulin unit and a pair of symmetrically arranged side folding tarpaulin units.

[0008] Furthermore, the side folding tarpaulin unit cooperates with the front folding tarpaulin unit in a manner of bending and extending inwardly, so as to achieve folding in a manner in which the bent parts overlap each other.

[0009] Furthermore, the pleated portion and the folded portion are made of the same material but have different thicknesses.

[0010] Furthermore, the hardness of the pleated portion and the folded portion is different.

[0011] Furthermore, when the hardness of the pleated portion is greater than that of the folded portion, the pleated portion gradually accumulates from bottom to top under the guidance of its own weight.

[0012] Furthermore, when the hardness of the pleated portion is less than that of the crease portion, the pleated portion is folded toward the crease portion under the guidance of the prestress of the crease portion.

[0013] Furthermore, the crease portion is a strip of TPU with a V-shaped cross section and a prefabricated crease.

[0014] Furthermore, when the folding tarpaulin unit is folded, the crease portion guides the pleated portion in a left-right alternating manner to achieve regular and orderly folding.

[0015] Furthermore, a welt is fixed along the edge of the folded portion at the end.

[0016] Beneficial effects of the present invention: In terms of the overall technical solution, the sunroof assembly uses a pair of electric struts as driving power to cooperate with the strut bracket to slide in the guide rail assembly, so that the glass mounting bracket swings upward or downward with the hinge assembly as the center of the circle, thereby realizing the opening or closing of the canopy or tarpaulin. At the same time, the strut bracket cooperates with the self-priming lock in the guide rail to realize the opening of the glass assembly at different preset angles.

[0017] In terms of specific structure, 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 guidance of the crease part. This avoids the problem in the prior art that when a large area of ​​tarpaulin is stacked downward in disorder, it will accumulate on the mechanical assembly and the guide rail assembly, hindering the smooth operation of the glass assembly.

[0018] The sunshade curtain assembly adopts a method similar to the prior art, where a motor drives the crossbeam to slide along the guide rail through a flexible shaft and a slider to guide the curtain to unfold or retract. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following combination Figures 1 to 4 , the specific contents of the present invention are described in detail through specific embodiments. Example 1

[0027] The liftable canopy assembly comprises a glass assembly 1, a frame assembly 2, a pair of mechanical assembly 3, a tarpaulin assembly 4, and a sunshade assembly 5. The specific structure and working principle of each component are described below in the order of the drawings.

[0028] like Figure 1a , Figure 2 As shown, the sunshade 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 assembly 22, a pair of sliders 54 slidably limited in the guide rail assembly 22, a crossbeam 51 fixed between the sliders 54 for guiding the movement of the curtain 56, and a flexible shaft 58 connected between the motor 55 and the sliders 54. At the same time, in order to ensure the sealing of the outer edge of the canopy 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 scratching 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 can be slidably limited in the preset flexible shaft slide groove 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, 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. The two sides of the curtain 56 are fixed on the curtain clamping strip 57 and are clamped in the slide groove on the inner side of the guide rail assembly 22, thereby driving the curtain 56 to unfold or retract.

[0029] like Figure 2 As shown, the glass assembly 1 includes a glass insert 12 fixed to the top of the car through a PU 13 and a laminated glass 11 fixed to the glass insert 12 through an adhesive.

[0030] like Figure 2 As shown, 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 arranged on the front seat frame assembly 23 or the rear seat frame assembly 21. The ECU assembly 24 is connected to the electric control components such as the motor 56, the electric strut 33 and the self-priming lock 35 through the wiring harness assembly located in the seat frame assembly 2, thereby controlling the action of the corresponding assembly by triggering a preset program.

[0031] like Figure 1b As shown, the guide rail assembly 22 includes an outer rib for fixing the roof frame, a U-shaped track portion in the middle, and an inner sunshade sliding groove portion for cooperating with the curtain cloth to extend. The U-shaped track also includes an outer slideway for cooperating with the mechanical group and an inner slideway for fixing the U-shaped tarpaulin 43, which are parallel and spaced from each other.

[0032] like Figure 2 As shown, the mechanical assembly 3 includes a hinge assembly 31 fixed at the front end of the guide rail assembly 22, a strut bracket 34 slidably limited in 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-priming lock 35 installed in the guide rail assembly 22 for locking the sliding position of the strut bracket 34. The extension of the electric strut 33 is controlled by the vehicle electronic control assembly to adjust the opening degree of the glass mounting bracket 32, and the strut bracket 34 is locked and positioned to the corresponding position. Specifically, when the canopy is closed, the strut bracket 34 slides backward along the guide rail assembly 22 to the self-priming lock 35 at the end; when the canopy is opened, according to the size of the opening angle, the strut bracket 34 slides from back to front along the guide rail assembly 22 to the self-priming lock 35 at the corresponding position. In this embodiment, three sets of self-priming locks 35 are taken as an example, and the number can be increased or decreased according to the specific customization.

[0033] like Figure 3 As 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, which are connected in sequence and fixed at the bottom to the front end of the guide rail assembly 22; so that the four connecting points constitute an unequal length double crank mechanism, and the ends on the same side 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, the canopy is closed, that is, Figure 3The upper bracket 312 is in the state of being in use, the inner end of the upper bracket 312 is tilted downward, the middle end of the upper bracket 312 is 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 (not shown), and the upper bracket 312 is tilted upward, so that the quadrilateral swings to the outer end to a preset position. At this time, the upper bracket 312 and the lower connecting rod 311 form a maximum angle. It is known to those skilled in the art that, under normal circumstances, in order to reduce wind resistance and wind noise during driving, the tarpaulin assembly 4 is unfolded at the rear side. If the use environment is designed to be opened in the non-driving state, the tarpaulin assembly 4 can also be unfolded at the front side (not shown). To facilitate the installation of the glass assembly 1, the glass mounting bracket 32 ​​used to fix the glass insert 12 is fixed to the outer end of the upper bracket 312.

[0034] like Figure 1a , Figure 1b , Figure 1c , Figure 4 As shown, the U-shaped tarpaulin 43 can be folded and matched between the two sets of annular bracket assemblies. According to the conventional design in the art, it is preferred to use an integrally formed annular bracket assembly, but in order 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 an independent annular tarpaulin upper bracket 44 fixed below the glass assembly 1, and the lower bracket assembly is designed as a split structure, specifically including a pair of tarpaulin side brackets 45, a tarpaulin front bracket 48 and a tarpaulin rear bracket 49 located therebetween, a rear corner bracket 46 as a transition section between the tarpaulin side bracket 45 and the tarpaulin front bracket 48, and a front corner bracket 47 as a transition section between the tarpaulin side bracket 45 and the tarpaulin front bracket 48. When transitioning from the tarpaulin side bracket 45 to the tarpaulin rear bracket 49, the height is gradually raised, that is, the horizontal plane where the tarpaulin rear bracket 49 is located is higher than the horizontal plane where the tarpaulin side bracket 45 is located, thereby avoiding blocking the normal unfolding of the curtain of the sunshade curtain assembly 5.

[0035] in addition, Figure 4 The vertical texture on the middle U-shaped tarpaulin 43 is merely the remnant of the structural line generated during the CAD modeling process, and does not represent any technical feature in the technical solution, nor is it used to limit the protection scope of the present invention. Example 2

[0036] The U-shaped tarpaulin 43 of the present invention can further adopt the following scheme, so that it can be stored completely in a preset manner when folded, avoiding the situation where the tarpaulin cannot be closed normally or the sunshade is blocked from rolling up due to random folding.

[0037] 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 pleated portions 431 made of a first material and a pleated portion 431 made of a second material, which are arranged at intervals along a first direction and extend along a second direction. Adjacent pleated portions 431 and folded portions 432 are fixed along the second direction by bonding or sewing. The two outermost ends of the U-shaped tarpaulin 43 are pleated portions 431. Preferably, the tarpaulin lower fillet 41 and the tarpaulin upper fillet 42 are fixed in the pleated portion 431 by bonding or sewing.

[0038] Among them, in the front folding tarpaulin unit, the first direction usually refers to the vehicle height direction, and the second direction usually refers to the vehicle horizontal direction; in the side folding tarpaulin unit, the first direction usually refers to the vehicle height direction, and the second direction usually 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 pleated parts 431 and the crease parts 432, the unfolding angle of the front side of the tarpaulin assembly 4 is greater than the rear side, and the elasticity of the tarpaulin assembly 4 material itself, when describing the direction of the tarpaulin assembly 4, it does not refer to a unique direction positioning, but a collection 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 refers to a collection of action trends.

[0039] like Figure 1b As shown, when the canopy is opened, the glass assembly 1 drives the upper molding 42 embedded therein to move upward along an arc through the tarpaulin upper bracket 44, and the upper molding 42 sequentially pulls the pleated portion 431, the adjacent folded 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.

[0040] like Figure 1c As 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, the pleated portion 431 and the crease portion 432 are both made of nylon cloth with a waterproof coating, and the material thickness of the pleated portion 431 is greater than that of the crease portion 432, the hardness differentiation can be achieved, and the pleated portion 431 is gradually accumulated from bottom to top under the guidance of its own weight until the glass assembly 1 is completely closed.

[0041] When the hardness of the pleated portion 431 is less than that of the crease portion 432, for example, when the pleated portion 431 is made of a light and flexible material, such as a mesh, it is difficult to fold in a preset manner, so it is usually stored in a rolling manner. To ensure normal folding use, the crease portion 432 is made of TPU, TPE, etc. with a prefabricated V-shaped crease. When the glass assembly 1 is closed downward, the lighter pleated portion 431 is folded and stacked in the direction of the crease portion 432 under the guidance of the prestressed elastic force of the crease portion 432, and the stacking unit with a larger mass at the bottom falls back to the guide rail assembly 22 under the guidance of its own weight, and the lighter pleated portion 431 at the upper part continues to be folded and stacked in the direction of the crease portion 432 under the guidance of the crease portion 432 until the glass assembly 1 is completely closed, thereby avoiding the disorderly storage of the U-shaped tarpaulin 43 during the closing process of the glass assembly 1. Example 3

[0042] When the design purpose is a roof tent that can be deployed when not driving, the extension distance of the support rod bracket 34 can be further increased, and the stroke of the support rod bracket 34 can be adjusted accordingly, so that the head space when the canopy is opened can be further increased on the basis of Example 1 or Example 2, so that it can be used as a roof tent, and it is very simple and convenient to use and store, and there is no need to purchase an additional tent fixed on the roof. Example 4

[0043] When the design purpose is to be a roof tent that can be deployed in a non-driving state, a pair of electric support rods 33 can be added to the front to further increase the head space when the roof is opened.
