[0027] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. 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.

[0028] like Figure 1 and Figure 2 As shown, this application provides an installation structure for a sunshade 100, which is mounted on a support device 200. The support device 200 can be various types of handcarts, such as the campervan shown in the attached figure.

[0029] The campervan includes a frame and a flexible lining 220 set within the frame to form a seating space 13. Figure 2(The thin dotted lines in the image indicate this). The seating space 13 is for children to ride in. The frame has wheels at the bottom and includes two first side frames 210 arranged opposite each other, and a base frame 230 connected between the two first side frames 210. The two first side frames 210 and the base frame 230 together form the aforementioned seating space 13. The base frame 230 is a foldable structure. For example, the base frame 230 includes a joint 231 and a front base frame 232 and a rear base frame 233 hinged to both sides of the joint 231. The other end of the front base frame 232 is hinged to the front first side frame 210, and the other end of the rear base frame 233 is hinged to the rear first side frame 210. Figure 2 and Figure 5 As shown, when folded, the two first side frames 210 are close to each other; when unfolded, the two first side frames 210 are far apart. The left and right sides of the frame are open, facilitating children's access to the seating space 13.

[0030] like Figures 1-5 As shown, the awning 100 includes a tarpaulin 190 ( Figure 2 The awning, as shown in the bold dashed lines, comprises a support member 110 and a swing member 120. The tarpaulin 190 is made of a flexible material, such as woven fabric, non-woven fabric, or a polymer film. The tarpaulin 190 is connected to and unfolded by the support member 110. The swing member 120 is pivotally connected to the support device 200 about a first axis 11, and the support member 110 is pivotally connected to the swing member 120 about a second axis 12. The first axis 11 and the second axis 12 are not collinear. This awning has two degrees of rotational freedom, and the support member 110 and the swing member 120 can be positioned at multiple angles relative to the support device 200. Ultimately, this allows for more angles for the awning and a greater height relative to the support device 200 compared to existing technologies, resulting in fewer limitations in its use.

[0031] In some embodiments, the awning 100 is mounted on the first side frame 210. In the figure, there are two awnings 100, which are respectively mounted on two first side frames 210. The swing member 120 has a first end and an opposite second end. The first end is connected to the bearing device 200, and the support member 110 is connected to the second end of the swing member 120.

[0032] The awning 100 has a usable state and a folded state. In the usable state, the second end of the swing member 120 is away from the supporting device 200, and the support member 110 rotates away from the swing member 120. At this time, the awning 190 is unfolded and located above the seating space, with the first end located below the second end, and the first axis 11 is lower than the second axis 12. Furthermore, the awning 190 extends and connects with the swing member 120, providing a tighter cover and improving the shading effect.

[0033] In the retracted state, the second end of the swing member 120 is close to the supporting device 200, and the support member 110 rotates and moves closer to the swing member 120, causing the awning 190 to fold up. In the retracted state, the first end is above the second end, and the first axis 11 is higher than the second axis 12. Both the first axis 11 and the second axis 12 are horizontally arranged, and further, they are parallel to each other. In the retracted state, the support member 110 and the swing member 120 overlap, reducing the volume of the awning 100 after folding. Furthermore, in the retracted state, the awning 100 is located to the side of the seating space 13, for example... Figure 4 The central awning 100 is located on the outside of the supporting device 200.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the first side frame 210 includes extending uprights 211 and crossbars 212 connecting the uprights 211, with one or more crossbars 212. Two swing members 120 are respectively connected to the outer sides of the two uprights 211. Each swing member 120 includes a main body 121 and a first connecting seat 122 connected to one end of the main body 121. The first connecting seat 122 is connected to the bearing device 200. The support member 110 includes an arc-shaped rod 113 and a base 114 connecting both ends of the arc-shaped rod 113. The swing member 120 is provided with a second connecting seat 123 pivotally connected to the base 114. The arc-shaped rod 113 is made of an elastic material, such as thin steel wire, which can adaptively deform in a retracted state and under external force to further reduce the overall volume of the device. For example... Figure 2 , Figure 4 and Figure 5 As shown, the support device 200 includes a handle 240 rotatably mounted on the frame, and an elastic return member, such as a torsion spring, that drives the handle 240 to rotate and approach the frame. The handle 240 is located on the outside of one of the first side frames 210. If the awning 100 is installed on the side where the handle 240 is located, during storage, the handle 240 is rotated to move it away from the frame, and then the awning 100 is folded to approach the frame. Releasing the handle 240 resets it and compresses the awning 100, causing the support member 110 to deform appropriately so that the handle 240 is closer to the frame.

[0035] Among them, such as Figure 2 As shown, the column 211 includes a vertically extending straight section 2111 and a curved section 2112 connected to the top of the straight section 2111 and extending outward. A crossbar 212 connects the two curved sections 2112. This creates a storage space 213 for the first side frame 210 below each curved section 2112. In the retracted state, the awning 100 is partially or entirely located within this storage space 213.

[0036] In a preferred embodiment, there are two arc-shaped rods 113, namely a left arc-shaped rod 111 and a right arc-shaped rod 112 relative to the base 114. Both the left and right arc-shaped rods are U-shaped structures and are fixedly connected to the base 114. The left arc-shaped rod 111 includes a first segment 1111 and a second segment 1112, as shown below. Figure 2 and Figure 4 As shown, the first segment 1111 is a straight rod extending upwards at an angle, and the second segment 1112 is an arc-shaped rod extending upwards. In the retracted state, the second segment 1112 of the support member 110 is adapted to the curved segment 2112 of the first side frame 210.

[0037] like Figure 2 As shown, in one embodiment, the length L1 of the left arc-shaped rod 111 is greater than the length L2 of the right arc-shaped rod 112. In a preferred embodiment, L1:L2 = 3.5-5. In the use state, the left arc-shaped rod 111 is located directly above the seating space, and the right arc-shaped rod 112 is located diagonally above the seating space. In the storage state, the left arc-shaped rod 111 and the swing member 120 coincide in the height direction.

[0038] In other embodiments, there are multiple support members 110, and the tarpaulin 190 extends between the multiple support members 110. The multiple support members 110 and the swing member 120 are coaxially rotatably connected.

[0039] like Figures 8-10 As shown, in one embodiment, a third connecting seat 214 is provided on the first side frame 210 and pivotally connected to the first connecting seat 122. The installation structure of the awning includes a first positioning member of the positioning swing member 120. In the figure, the third connecting seat 214 is provided with multiple first positioning members 2141 arranged circumferentially around the first axis 11. The first positioning members 2141 have a toothed structure, and their two circumferential sides are inclined surfaces. Correspondingly, the first connecting seat 122 is provided with a first positioning groove 1221 that cooperates with the first positioning members 2141. A first spring 310 is provided between the first connecting seat 122 and the third connecting seat 214 to keep them close to each other. In actual operation, an external force is applied to drive the swing member 120 to rotate. Under the action of the inclined surfaces, the two connecting seats move away from each other, and the first positioning members 2141 disengage from the first positioning groove 1221. After the external force is released, under the action of the first spring 310, the first positioning members 2141 extend into the first positioning groove 1221 and restrict the rotation of the swing member 120.

[0040] Furthermore, the installation structure of the awning includes a limiting structure that restricts the rotation limit of the swing member 120. The limiting structure includes a first blocking part 2142 provided on the third connecting seat 214, and a first limiting part 1222 and a second limiting part 1223 provided on the first connecting seat 122. When the swing member 120 rotates away from the seating space to the first limit position (at which time the swing member 120 extends vertically), the first limiting part 1222 abuts against the first blocking part 2142. When the swing member 120 rotates closer to the seating space to the second limit position, the second limiting part 1223 abuts against the first blocking part 2142.

[0041] like Figures 11-13 As shown, in one embodiment, the installation structure of the awning includes a second positioning member of the positioning support. In the figure, a plurality of second positioning members 1231 are arranged circumferentially around the second axis 12 on the second connecting seat 123. A plurality of second positioning grooves 1141 are provided around the second axis 12 on the base 114 of the support member 110. A second spring 320 is provided between the second connecting seat 123 and the base 114 to keep them approaching each other. The surface of the second positioning member 1231 near the second positioning groove 1141 is an arc surface, and the second positioning groove 1141 is an arc groove. The rotation operation involves applying an external force to the support member 110, causing the base 114 and the second connecting seat 123 to move away from each other, and the second positioning member 1231 to exit the second positioning groove 1141. After releasing the external force, under the action of the second spring 320, the second connecting seat 123 and the base move closer together, and simultaneously the second positioning member 1231 extends into the second positioning groove 1141.

[0042] Furthermore, the installation structure of the awning includes a limiting structure that restricts the rotation limit of the support member 110. The limiting structure includes a second blocking part 1232 provided on the second connecting seat 123 and a third limiting part 1142 provided on the base 114. When the swing member 120 rotates away from the swing member 120 to the limit position, the third limiting part 1142 abuts against the second blocking part 1232.

[0043] The installation structure of the awning of this application includes a support member and a swing member connecting the awning fabric. The swing member is pivotally connected to the load-bearing device, and the support member and the swing member are pivotally connected. The two degrees of freedom make the usable height and usable angle of the awning fabric relative to the load-bearing device more diverse than the prior art.

[0044] 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.

[0045] 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.
