The first awning surface support rod 11 is rotatably connected in the L-shaped limiting groove. The L-shaped limiting groove is used to limit the rotational freedom of the first awning surface support rod 11 relative to the first top support member 1; when the two first awning surface support rods 11 rotate upward by an angle greater than 180°, the L-shaped limiting groove can limit the first awning surface support rod 11 from continuing to rotate relative to the first top support member 1, and the awning surface support rod is limited at the first limiting position 61 and the first limiting position 62. When in the first limiting position 61, the awning surface support rod is arranged in a vertical state; when in the second limiting position 62, the awning surface support rod is arranged in a horizontal state; and when the first top support member 1 or the second top support member 2 moves upward from bottom to top, the awning surface support rod transitions from a vertical state to a horizontal state.

[0039] As Figures 1 to 10As shown in the figure, the second supporting member 2 and the first supporting member 1 are rotatably connected in the horizontal direction, and the first supporting member 1 and the second supporting member 2 are locked and fixed through the locking assembly 3. One end of each of the two second awning struts 21 is pivotally connected to the second supporting member 2, and the two second awning struts 21 are arranged in a straight line and are respectively located on both sides of the second supporting member 2. The two second awning struts 21 rotate in opposite directions, and the two second awning struts 21 rotate in the up and down direction. The two ends of the second supporting member 2 are also provided with the same limiting mechanism 6 as that of the first supporting member 1. The reverse folding realized by the combination of the second supporting member 2 and the first supporting member 1 can more comprehensively support the awning surface, further improve the awning surface support effect, and further improve the aesthetic and practicality. The first supporting member 1 and the second supporting member 2 are rotatably connected, so that the first awning strut 11 and the second awning strut 21 are arranged at a certain angle. In this embodiment, the two first awning struts 11 and the two second awning struts 21 are arranged in an "X" shape, and can also be arranged in a "cross" shape. At the same time, the angle adjustment by multiple first awning struts 11 and multiple second awning struts 21 can be adapted to different chairs or vehicle bodies, greatly improving the adaptability and versatility of the sunshade awning. And the first supporting member 1 and the second supporting member 2 are locked and fixed through the locking assembly 3. The rotation connection between the first supporting member 1 and the second supporting member 2 is convenient for adjustment, and the locking assembly 3 is convenient for fixing after adjustment, so that it can be further adapted to different chairs or vehicle bodies and awnings with different areas, further improving the overall versatility and adaptability.

[0040] As Figures 2 to 5 shown, a horizontally penetrating limiting hole 22 is formed in the second supporting member 2, and the first supporting member 1 is rotatably connected in the limiting hole 22; the limiting hole 22 is used to limit the rotation angle of the first supporting member 1 relative to the second supporting member 2; both the first supporting member 1 and the second supporting member 2 are provided with vertically penetrating connection holes 4; the locking assembly 3 includes a locking screw 31 and a locking nut 32; one end of the locking screw 31 passes through the two connection holes 4 and is locked and connected with the locking nut 32, so that the first supporting member 1 and the second supporting member 2 are locked and fixed. Through the limiting hole 22, the rotation angle of the first supporting member 1 and the second supporting member 2 can be further limited. At the same time, the disassembly, adjustment and fixing are convenient through the locking screw 31 and the locking nut 32, further improving the use convenience and the use experience.

[0041] As Figure 1 and Figure 2As shown, one end of the first awning surface support rod 11 away from the first support top member 1 is connected with a first movable joint 7. The first movable joint 7 is simultaneously clamped and arranged with the first support top member 1 and one end of the first awning frame support rod 13. Through the first movable joint 7, the first awning surface support rod 11 can rotate towards or away from the first support top member 1. One end of the second awning surface support rod 21 and one end of the second awning frame support rod 23 are also clamped and connected with a second movable joint 8. Both the first awning frame support rod 13 and the second awning frame support rod 23 are connected with awning frame joints 5 for supporting the frame body. In this embodiment, a limiting mechanism 6 for restricting rotation is provided on both the first movable joint 7 and the second movable joint 8. The limiting mechanism 6 on the movable joint is an L-shaped limiting groove with an opening downward, and has an opposite direction to the limiting mechanism 6 on the first support top member 1 and the second support top member 2, so as to prevent the first awning frame support rod 13 and the second awning frame support rod 23 from bending upward, facilitating better folding of the first awning frame support rod 13 and the second awning frame support rod 23. Through the movable joint, the first support top member 1 and the second support top member 2, the first awning surface support rod 11, the second awning surface support rod 21, two first awning frame support rods 13 and two second awning frame support rods 23 can be in a storage state (as Figure 10 shown) and an unfolded state (as Figure 1 shown).

[0042] As Figure 1 shown, in the actual use process, after both the first awning frame support rod 13 and the second awning frame support rod 23 are fixedly connected with the chair body through the awning frame joints 5, the distance between the combination of two first awning surface support rods 11 on the same straight line is greater than the distance between two support and positioning points on the awning surface of the sunshade awning; the distance between the combination of two second awning surface support rods 21 on the same straight line is greater than the distance between two support and positioning points on the awning surface of the sunshade awning. Thus, when the first awning frame support rod 11 and the second awning frame support rod 12 are unfolded and fixed, it can be ensured that the first support top member 1 and the second support top member 2 in the center are in an upward propping state, further preventing the first awning frame support rod 11 and the second awning frame support rod 12 from folding and closing downward after fixation, and finally achieving the purpose of good propping stability and propping support for the awning surface.

[0043] As Figures 6 to 8As shown in the figure, the first awning support rod 13 and the second awning support rod 23 on the same side are simultaneously connected to an awning joint 5. By connecting and connecting to an awning joint 5 through the above structure, it is convenient to connect two awning support rods to the same point, and then it is convenient to install them on the chair better, improving the convenience and diversity of installation. The awning joint 5 includes a first positioning pivot 51, a first pivot joint 52, a second pivot joint 53, a second positioning pivot 54, a spring 55 and a connecting screw 56; the first positioning pivot 51 is provided with a pivot section 511 and a limit section 512; the first positioning pivot 51 is an adjustment base, the pivot section 511 is a pivot shaft, and the limit section 512 is a pivot stop; a card slot for clamping with the chair body is provided on the adjustment base, and a chair card joint is provided on the chair body, and the two are vertically inserted and matched, which is convenient for disassembly and assembly and improves the convenience of use. The first pivot joint 52 is rotatably connected to the outer peripheral wall of the pivot section 511 and is connected to the first awning support rod 13; the second pivot joint 53 is rotatably connected to the outer peripheral wall of the pivot section 511 and is connected to the second awning support rod 23, and the second pivot joint 53 is located between the limit section 512 and the first pivot joint 52. The second positioning pivot 54 restricts the first pivot joint 52 and the second pivot joint 53 from moving excessively in the axial direction. The spring 55 is arranged on the pivot section 511 and drives the first pivot joint 52 and the second pivot joint 53 to always move in the direction towards the limit section 512. The second positioning pivot 54 is a gland, the gland is sleeved on the first pivot joint 52, the two axial ends of the spring 55 respectively abut against the end face of the gland and the inner end face of the first pivot joint 52, and the gland is fixedly connected to the pivot section 511 by the connecting screw 56 passing through the gland and being threadedly connected to the pivot section 511, realizing the synchronous axial movement of the gland and the pivot section 511. The second pivot joint 53 and the limit section 512 can abut against each other under the action of the spring 55. A plurality of first positioning parts 513 are convexly arranged at intervals along the circumferential direction on the limit section 512. In this embodiment, the first positioning parts 513 are spherical positioning protrusions. A plurality of second positioning parts 531 are recessed on the second pivot joint 53 and are circumferentially distributed and are in positioning cooperation with the first positioning parts 513. In this embodiment, the second positioning parts 531 are spherical positioning grooves. In actual use, the installation positions of the positioning protrusions and the positioning grooves can also be interchanged, and the positioning effect can also be achieved. Through the first positioning parts 513 and the second positioning parts 531, it is convenient to carry out installation positioning, convenient for rotational adjustment when the two are separated, and locked and fixed when the two are positioned, improving the convenience of use.Through the above structure, when no external force is applied, the spring 55 causes the second pivot joint 53 to press against the first positioning pivot 51, so that the first positioning portion 513 and the second positioning portion 531 are plugged and positioned and cannot rotate. When the angle needs to be adjusted, the first positioning pivot 51 is pulled outward to compress the spring 55, so that the first positioning pivot 51 is separated from the second pivot joint 53, and then the pivot section 511 can be rotated. After adjusting the appropriate angle, the first positioning pivot 51 is released, and the spring 55 automatically presses the second pivot joint 53 against the first positioning pivot 51, so that the two are retracted and fixed. The structural design is ingenious and convenient for disassembly and assembly, thereby improving the convenience of disassembly and assembly and the user experience. The first positioning pivot 51 is provided with a chair vertical card slot that is engaged with the chair card joint on the chair body.

[0044] In the process of using the sunshade frame of this embodiment, the first top supporting member 1 and the second top supporting member 2 are pulled upward together, and the two first awning surface support rods 11 and the two second awning surface support rods 21 are in the same plane (such as Figure 1 As shown in the figure, the first supporting member 1 and the second supporting member 2 can be rotated and adjusted to match chairs of different sizes to improve adaptability; at the same time, the chair vertical slot on the first positioning pivot 51 is engaged with the chair clamping joint on the chair body to fix it.
