[0029] The first hinge unit 11 comprises a spherical base 111 and a first hinge rod 112, the spherical base 111 is provided with three first mounting grooves, the first hinge rod 112 is also provided with three, and the three hinge rods 112 are respectively arranged in the first mounting grooves in a rotatable manner, specifically, a rotating pin is arranged in the first mounting groove, the first hinge rod 112 is rotatably connected with the rotating pin, thereby realizing the hinge connection between the first hinge rod 112 and the spherical base 111.

[0030] A hole is arranged in the middle of the first hinge rod 112, the first hinge rod 112 is connected with the rotating pin arranged in the first mounting groove through the hole, and both ends of the first hinge rod 112 extend to the outside of the spherical base 111, so as to facilitate the connection between the first hinge rod 112 and the support rod 12, preferably, the support rod 112 is a hollow steel pipe, the two ends of the first hinge rod 112 extending to the outside of the spherical base 111 are provided with circular connecting portions, the outer diameter of the circular connecting portions is slightly smaller than the inner diameter of the support rod 12, so as to facilitate the insertion of the support rod 12 into the circular connecting portions, thereby realizing the hinge connection between the support rod 12 and the spherical base 111, the circular connecting portions and one end of the support rod 12 are both provided with holes, and a bolt is inserted through the holes of the circular connecting portions and the hole of one end of the support rod 12, so that the connection between the support rod 12 and the first hinge rod 112 is more stable and not easy to loosen.

[0031] One support unit 1 comprises one first hinge unit 11 and six support rods 12, and adjacent two support units 11 are connected through the support rods 12 and the first hinge units 11.

[0032] As Figure 2As shown, preferably, the first mounting slots are uniformly distributed on the spherical base 111, the first articulated rods 112 rotate in the first mounting slots at an angle ranging from 0 to 90°, when the three first articulated rods 112 are all at the position of 0 degree, the entire support unit is in the state of contraction; when the three first articulated rods 112 are all at 90°, the entire support unit is in the fully open state, at this time, the support rods 12 connected on different first articulated rods 112 are mutually at 90° angle, at this time, one first articulated unit 11 and six support rods 12 form a cuboid mechanism, this structure has high stability, therefore, the support unit 1 can play a very stable supporting role when being opened.

[0033] The second articulated unit 21 comprises a disc-shaped base 211 and second articulated rods 212, the disc-shaped base 211 is provided with three second mounting slots, the number of the second articulated rods 212 is also three, the three second articulated rods 212 are respectively rotatably arranged in the second mounting slots, specifically, the second mounting slots are provided with rotating pins, the second articulated rods 212 are rotatably connected with the rotating pins in the second mounting slots, thereby realizing the articulation of the second articulated rods 212 with the disc-shaped base 211.

[0034] The middle of the second articulated rod 212 is provided with a hole, the second articulated rod 212 is rotatably connected with the rotating pin arranged in the second mounting slot through the hole, and the two ends of the second articulated rod 212 extend to the outside of the disc-shaped base 211, so as to facilitate the connection of the second articulated rod 212 with the control rod 22, and the control rod 22 can rotate with the second articulated rod 212 around the rotating pin in the second mounting slot, preferably, the control rod 22 is a hollow steel pipe, the two ends of the second articulated rod 212 extending to the outside of the disc-shaped base 211 are provided with circular connecting parts, the outer diameter of the circular connecting parts on the second articulated rod 212 is slightly smaller than the inner diameter of the control rod 22, so as to facilitate the insertion of the control rod 22 on the second articulated rod 212, the circular connecting parts on the second articulated rod 212 are provided with holes, one end of the control rod 22 is also provided with a hole, and the holes in the circular connecting parts on the second articulated rod 212 and the hole on the control rod 22 are penetrated by a pin, so that the connection of the control rod 22 with the second articulated rod 212 is more stable and not easy to loosen. The two ends of the second articulated rod 212 are respectively connected with the connecting rod 24 and the first articulated rod 112 on the first articulated unit 11 through the control rod 22, that is, one end of the second articulated rod 212 is connected with the first articulated rod 112 through the control rod 22, the other end of the second articulated rod 212 is articulated with the connecting rod 24 through the control rod 22. When the support unit 1 is in the process of contraction and opening, the control rod 22 drives the rib unit 2 to contract or open.

[0035] The support structure further comprises a connecting unit 3, one end of the connecting unit 3 is fixedly connected with the first hinge unit 11, and the other end of the connecting unit 3 is rotatably connected with the control rod 22 away from the second hinge unit 21. It can be understood that the connecting unit 3 plays a role in connecting the support unit 1 and the rib unit 2. By arranging the connecting unit 3 between the support unit 1 and the rib unit 2, one end of the connecting unit 3 is fixedly connected with the first hinge rod 112 to ensure the stability of the support of the support unit 1 to the rib unit 2, and the other end of the connecting unit 3 is rotatably connected with the control rod 22 to control the direction of rotation of the control rod 22. In this way, by arranging the connecting unit 3 between the support unit 1 and the rib unit 2, the stability of the support can be ensured, and the direction of rotation of the control rod can also be controlled, thereby enabling the entire rib unit 2 to be smoothly opened.

It can be understood that two surrounding rods 25 are hingedly connected between adjacent two connecting rods 24, and the surrounding rods 25 located between adjacent two connecting rods 24 are also hingedly connected with each other. In this way, the connecting rod 24 and the surrounding rod 25 are hingedly connected to form the top of the rib unit 2, which can be retracted and expanded together with the support unit 1. This top is used to install a canopy, so that the rib unit 2 can realize the functions of sun-shading and rain-shielding after being expanded.

[0037] One of the support structures comprises three support units 1 and one rib unit 2. Adjacent two support units 1 are connected through the support rod 12 and the first hinge unit 11. As described above, the support rods 12 connected with different first hinge rods 112 form a 90° angle when the support unit 1 is expanded. At this time, one first hinge unit 11 and six support rods 12 form a cubic mechanism. The three support units 1 are connected through the support rod 12 and the first hinge unit 11. The rib unit 2 is arranged above the three support units 1. The rib unit 2 is connected with the first hinge units of the three support units 1 through the control rod 22. In this way, the three support units 1 form stable support for the rib unit 2 when being expanded, and the rib unit 2 can be retracted and expanded together with the support unit 1.

[0038] The application further provides a sunshade canopy, comprising the sunshade cloth and at least one support structure as described above, the sunshade cloth is arranged on the rib unit 2, and functions as sunshade or rain shelter when the rib unit 2 is opened, and adjacent support structures are connected through the support rod 12 and the first hinge unit 11, and different numbers of support structures can be connected according to different scene requirements.
