Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] First, for ease of description, the term "end" in the text refers to the endpoint of the structure, or a point or region in that lateral direction, or a specific structure connected to that point or region.

[0047] See Figures 1-4 This application provides a sunshade device 1000, including a support frame 100 and a sunshade cloth 200. The support frame 100 includes a column assembly 110 and a strut assembly 120 disposed on the top of the column assembly 110. The bottom of the column assembly 110 can be inserted into the ground, or as... Figure 4It connects to other carriers such as handcarts. The column assembly 110 includes a first column 111, a second column 112, a third column 113, and a fourth column 114. The four columns can be set vertically or at an angle, and the columns can extend vertically or bend to a certain extent when upright due to excessive length. This embodiment takes an example where the columns are set vertically and the bottom is connected to the handcart.

[0048] The strut assembly 120 includes a first strut 121, a second strut 122, a third strut 123, and a fourth strut 124. The first strut 121 connects to the first column 111 and the second column 112; the second strut 122 connects to the third column 113 and the fourth column 114; the third strut 123 connects to the first column 111 and the fourth column 114; and the fourth strut 124 connects to the second column 112 and the third column 113. The strut assembly 120 can be understood as forming a quadrilateral structure. The sunshade cloth 200 is unfolded and mounted on the strut assembly 120, specifically connected to each strut in a manner consistent with existing technology. In vertical projection, the sunshade cloth 200 has a rectangular, rhomboid, or other polygonal shape.

[0049] The sunshade device of this application connects each column through a strut assembly, which improves the structural strength of the support frame itself, and the strut assembly supports the unfolding of the sunshade cloth to provide the unfolding stability of the sunshade cloth.

[0050] In one embodiment, the first column 111, the second column 112, the third column 113, and the fourth column 114 define a rectangular space, meaning that the line connecting the four columns forms a rectangle on any horizontal plane. The first support rod 121 and the second support rod 122 form one group, and the third support rod 123 and the fourth support rod 124 form another group. The two groups of support rods are perpendicular to each other, and the two support rods in each group are parallel to each other, thus forming a rectangular structure with the four support rod assemblies.

[0051] Among them, such as Figure 2 and Figure 3 As shown, each support rod passes through the connected column, increasing the unfolding stability of the sunshade 200, and can extend to the edge of the sunshade 200. The ends of each support rod extend beyond the area defined by the column assembly, and the projected area of ​​the area formed by connecting all the ends sequentially is more than twice the projected area of ​​the area defined by the column assembly, preferably four to twelve times. It should be emphasized that the projected area of ​​the area formed by connecting all the ends sequentially is not necessarily the projected area of ​​the sunshade 200 when unfolded.

[0052] In one embodiment, a wind rope is connected to the sunshade 200, and one end of the wind rope is fixed to the ground by a ground nail.

[0053] In one embodiment, the sunshade device 1000 includes a retainer 300 for maintaining the relative positions of the columns. Preferably, the retainer 300 is disposed adjacent to the top of the columns to limit relative swaying between the columns and maintain the unfolding stability of the sunshade fabric 200. As illustrated, the retainer 300 includes a central seat 310 located at the center of the space defined by the column assembly, and connecting rods 320 connecting the central seat 310 and the columns.

[0054] The connecting rods 320 are telescopic structures. Each connecting rod 320 extends or retracts to drive the columns to move away from or towards each other. Alternatively, both ends of the connecting rods 320 are rotatably connected to the center seat 310 or the corresponding column. When each connecting rod 320 rotates vertically, it drives the columns to move closer together; when each connecting rod 320 rotates horizontally, it drives the columns to move away from each other. A locking mechanism is provided between the connecting rods 320 and the center seat 310 to keep each connecting rod 320 horizontal.

[0055] In one embodiment, each column is provided with a connector 140 for connecting struts at its top. As described above, the struts pass through the connector 140, which is cylindrical and sleeved and fixed to the top of the column. The two sets of struts are staggered vertically to allow the same connector to pass through both struts.

[0056] In one embodiment, the column and / or support rod is a telescopic structure or a multi-segment foldable structure for easy storage.

[0057] See Figures 4-8 This application also provides a handcart 4000, including a top-open load-bearing frame 410, a support frame 100, and a sunshade 200. The load-bearing frame 410 has wheels 411 at its bottom, and the support frame 100 has four uprights, each of which is detachably connected to the load-bearing frame 410. The sunshade 200 is unfolded and disposed on the support frame 100, and its vertical projected area (i.e., the sunshade area below) is more than twice that of the load-bearing frame 410, preferably four to twelve times.

[0058] The trolley's load-bearing frame can serve as a fixed support for the skeleton, and if the shade cloth has a large enough shade area, the trolley can form a large canopy for outdoor camping. Furthermore, the trolley is movable, allowing for adjustments to the shade position and making it more flexible to use.

[0059] Of course, if the area of ​​the sunshade is too large, it can be secured with guy ropes, which can also prevent the handcart from tipping over.

[0060] In one embodiment, the trolley also includes a liner fitted inside the support frame 410 to form a receiving space for loading items or carrying a child.

[0061] In one embodiment, the sunshade 200 extends beyond the support frame 410 in all directions on the vertical projection plane. The support frame 100 is structured similarly to that in the previous embodiment and will not be described again here. The sunshade 200 is unfolded and mounted on the strut assembly 120.

[0062] In one embodiment, the supporting frame 410 includes a base support frame 415, uprights 412 located at corner positions, and side supports 413 disposed between adjacent uprights 412. The bottoms of the four uprights are detachably connected to their respective uprights 412. In conjunction with the aforementioned support frame 100 structure, the bottoms of the first to fourth uprights are sequentially detachably connected to their respective uprights. The base support frame 415 has a rectangular structure and is rectangularly arranged corresponding to the first to fourth uprights. The side supports 413 have a foldable structure.

[0063] See Figure 6 and Figure 7 A connecting seat 414 is provided on the upright 412, and the bottom of the column (shown as the second column 112 in the figure) is inserted into the connecting seat 414. A locking mechanism is provided between the connecting seat 414 and the column to prevent the column from dislodging from the connecting seat 414.

[0064] The sunshade device of this application connects each column through a strut assembly, which improves the connection strength of the support frame itself, and the strut assembly supports the unfolding of the sunshade cloth to provide the unfolding stability of the sunshade cloth.

[0065] The handcart of this application has a load-bearing frame that can serve as a fixed support structure. Combined with the handcart's movable nature, it facilitates adjustment of the sunshade position and offers greater flexibility in use. If the sunshade fabric has a sufficiently large shading area, the handcart can form a large canopy for outdoor camping, providing even better sunshade.

[0066] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0067] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
