As will be appreciated by those skilled in the art, the awning cloth assembly 4 is typically deployed on the rear side for windage and wind noise during travel. If the use environment is designed to be open in a non-driving state, the awning cloth assembly 4 can also be unfolded at the front side, which is not shown. To facilitate the installation of the glass assembly 1, a glass mounting bracket 32 for securing the glass insert 12 is secured to the outboard end of the upper bracket 312.
As shown in fig. 1a, 1b, 1c, 4, the U-shaped tarpaulin 43 is foldably fitted between two collar-shaped bracket assemblies, preferably integrally formed ring-shaped bracket assemblies according to conventional designs in the art, but designed as a separate structure in order to avoid interference with the sunshade assembly 5. For example, in the present embodiment, the upper bracket assembly is a separate annular awning cloth 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 awning cloth side brackets 45, an awning cloth front bracket 48 and an awning cloth rear bracket 49 positioned therebetween, a rear corner bracket 46 as a transition section of the awning cloth side bracket 45 and the awning cloth front bracket 48, and a front corner bracket 47 as a transition section of the awning cloth side bracket 45 and the awning cloth front bracket 48. When the awning cloth side support 45 is transited to the awning cloth rear support 49, the awning cloth rear support 49 is gradually lifted in height, namely the horizontal plane of the awning cloth rear support 49 is higher than that of the awning cloth side support 45, so that the normal unfolding of the curtain cloth of the sunshade curtain assembly 5 is prevented.
In addition, the vertical texture on the U-shaped tarpaulin 43 in fig. 4 is only the structural line residue generated in the CAD modeling process, and does not represent any technical features in the technical solution, nor is it intended to limit the scope of the present utility model.
Example 2
The U-shaped awning cloth 43 of the present utility model may further adopt the following scheme, so that it is completely stored in a preset manner when folded, and the situation that the awning board cannot be normally closed or the sunshade screen is blocked from being rolled up due to random folding without regulations is avoided.
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 fold portions 431 made of a first material and fold portions 431 made of a second material which are arranged at intervals along a first direction and extend along a second direction, adjacent fold portions 431 and fold portions 432 are fixed along the second direction by bonding or sewing, and two outermost ends of the U-shaped tarpaulin 43 are provided with the fold portions 431. Preferably, the tarpaulin lower molding 41 and the tarpaulin upper molding 42 are fixed in the fold sections 431 by means of adhesion or stitching.
The front folding tarpaulin unit is characterized in that a first direction is usually the height direction of the vehicle, a second direction is usually the horizontal direction of the vehicle, and a side folding tarpaulin unit is usually the height direction of the vehicle, and a second direction is usually the length direction of the vehicle. Due to the folded storage and unfolding of the tarpaulin assembly 4 during use, the nonstandard shape of the folds 431 and folds 432, the unfolding angle of the front side of the tarpaulin assembly 4 is larger than the rear side, and the elasticity of the material of the tarpaulin assembly 4 itself, so that the orientation of the tarpaulin assembly 4 is not referred to the only orientation in the description of the orientation, but rather a collection of the trends of several scattering directions along a specific direction. That is, reference herein to the first direction or the second direction does not refer to the orthogonal direction of the height, width, length of the vehicle coordinate system, but refers to a collection of motion trends.
As shown in fig. 1b, when the roof is opened, the glass assembly 1 drives the upper molding 42 embedded therein to move upward in an arc shape by the tarpaulin upper bracket 44, and the upper molding 42 sequentially pulls the fold portion 431, the adjacent fold portion 432, the adjacent fold portion 431, and so on until the hinge assembly 31 reaches the maximum expansion angle, and the glass assembly 1 is completely opened.
As shown in fig. 1c, when the roof is closed, if the hardness of the fold portion 431 is greater than that of the crease portion 432, for example, nylon cloth with waterproof coating is used for both the fold portion 431 and the crease portion 432, and the material thickness of the fold portion 431 is greater than that of the crease portion 432, so that hardness distinction can be achieved, the fold portion 431 is gradually piled up from bottom to top under the self-weight guide until the glass assembly 1 is completely closed.
When the rigidity of the fold portion 431 is smaller than that of the fold portion 432, for example, when the fold portion 431 is made of a soft material with a relatively light weight, such as a mesh cloth, it is difficult to fold the folded portion in a predetermined manner, and thus, the folded portion is generally housed in a furling manner. To ensure proper folding use, crease 432 is made of pre-formed V-folded TPU, TPE, etc. When the glass assembly 1 is closed downwards, the fold parts 431 with lighter mass are folded and piled up towards the fold parts 432 under the guidance of the prestress elasticity of the fold parts 432, the piled up units with larger mass at the bottom fall back to the guide rail assembly 22 under the action of dead weight guidance, and the fold parts 431 with lighter mass at the upper part continue to be folded and piled up towards the fold parts 432 under the guidance of the fold parts 432 until the glass assembly 1 is completely closed, so that the glass assembly 1 is prevented from being randomly contained in the U-shaped tarpaulin 43 in the closing process.
Example 3
When the design application is that the roof tent which can be unfolded in the non-driving state, the stretching distance of the support rod support 34 can be further improved, and meanwhile, the travel of the support rod support 34 can be correspondingly adjusted, so that the roof space when the roof is opened can be further increased on the basis of the embodiment 1 or the embodiment 2, and the roof tent can be used as the roof tent, is easy and convenient to use and store, and does not need to additionally purchase the tent fixed on the roof.
Example 4
When the design is a roof tent which can be unfolded in a non-driving state, a pair of electric supporting rods 33 can be additionally arranged at the front part, so that when the roof is opened, the head space is further increased.
