[0043] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0044] Embodiment 1:

[0045] This embodiment provides a sunshade, comprising:

[0046] The frame comprises two sets of beams 1 arranged opposite to each other and columns 2 arranged at the connection between two adjacent beams 1;

[0047] The blade assembly is installed between the two groups of beams 1 and includes a plurality of sunshade blades 3 arranged at equal intervals, and one end of the sunshade blade 3 is rotatably connected to the beam 1, and a driving assembly 4 is provided between the other end and the beam 1;

[0048] A notch 5 is provided at the top of the column 2 for the crossbeam 1 to extend into, and a connecting block 6 is provided on the inner wall of the column 2 at one end of the notch 5, and assembly grooves 7 adapted to the connecting block 6 are provided at both ends of the crossbeam 1;

[0049] The connection block 6 and the column 2 can be welded, and a threaded hole is provided on the connection block 6. The bolts used for fastening pass through the crossbeam 1 and the inner wall of the assembly groove 7 and are threadedly connected with the threaded hole.

[0050] It can be seen from this embodiment that by providing a notch 5 for the crossbeam 1 to extend into the top of the column 2, the connection block 6 and the assembly groove 7 are arranged to facilitate the pre-clamping of the crossbeam 1 and the column 2, and then fasten them with bolts, which is convenient for assembly and disassembly;

[0051] And the operation is performed from the inner side of the beam 1, which effectively prevents the bolts from being exposed on the frame surface, and the top surface of the column 2 wraps the two connected beams 1 to eliminate the connection gap and improve the aesthetics.

[0052] Embodiment 2:

[0053] This embodiment provides a sunshade awning, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0054] Both ends of two adjacent beams 1 are provided with bevel angles 8;

[0055] Among them, the oblique angle 8 is 45°.

[0056] It can be seen from the present embodiment that by providing a 45° bevel 8 at both ends of the two beams 1, the tight fit of the two beams 1 after being matched at a right angle is improved, so that the two ends of the beam 1 can be close to the inner wall of the column 2, thereby facilitating the fit between the connecting block 6 and the assembly groove 7 as well as the connection strength and stability between the beam 1 and the column 2.

[0057] Embodiment 3:

[0058] This embodiment provides a sunshade awning, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component 4 includes:

[0059] A driven gear 40 is mounted on one end of the sunshade blade 3;

[0060] The rack 41 is slidably connected to the inner side of the beam 1 and meshes with the driven gear 40;

[0061] A driving gear 42 is mounted on the inner side of the beam 1 and meshes with the rack 41;

[0062] The rocker 43 is mounted on the bottom surface of the beam 1 and extends into the beam 1 to drive the driving gear 42 to rotate;

[0063] The rocker 43 includes a fixed section and a detachable section, the detachable end is clamped with the fixed section, and the fixed section passes through the bottom surface of the beam 1 and extends into the beam 1; the driving gear 42 is axially provided with a first rotating shaft, and the first rotating shaft is rotatably connected to the inner side surface of the beam 1;

[0064] Furthermore, the first rotating shaft is transmission-connected to one end of the fixed section located inside the crossbeam 1, and the transmission connection may adopt a worm gear structure or a structure in which two bevel gears are meshed;

[0065] At the same time, the driven gear 40 is axially provided with a second rotating shaft, and the second rotating shaft is rotatably connected to the inner side surface of the cross beam 1 .

[0066] It can be seen from this embodiment that the rocker 43 drives the driving gear 42 to drive the rack 41 to slide and then drive the driven gear 40 to rotate, thereby driving the rotation of the sunshade blade 3 to adjust the light and improve the comfort of the awning;

[0067] The meshing adjustment of the gear rack has high stability and good adjustment accuracy. The sunshade blade 3 can stably maintain any opening and closing angle. Specifically, the gear can stay at any angle between 0°-90°, and the meshing has a braking function. The teeth can be accurately positioned at any desired point, which solves the problem of inertia of the traditional blind buffer zone.

[0068] At the same time, the rocker 43 is set internally to avoid erosion caused by the intrusion of rainwater, extend the service life of the structure in which the rocker 43 is connected to the driving gear 42, improve the convenience of adjustment using the rocker 43, and avoid jamming after erosion.

By providing at least two strip grooves 44 and limiting the position by bolts 45, the stability of the rack 41 on the inner side of the beam 1 can be improved. Since the two points determine a straight line, the transmission between the rack 41 and the driving gear 42 and the driven gear 40 can be guaranteed.

[0074] Embodiment 5:

[0075] This embodiment provides a sunshade awning, which, in addition to the technical solutions of the above embodiments, also has the following technical features:
