Description

Technical Field

[0001] The utility model relates to the technical field of novel canopy brackets, in particular to a multi-layer stacked rod pull-out arc-shaped canopy support structure. Background Art

[0002] In modern society, with the development of technology, two-wheeled vehicles such as electric vehicles and motorcycles have become common means of transportation for people. Compared with cars, they are small in size and flexible in operation, and are suitable for medium and short-distance travel. However, two-wheeled vehicles lack devices for rain or sun protection. When the weather conditions are relatively bad, such as strong sunshine or heavy rainfall, it is inconvenient for people to drive electric vehicles and motorcycles, and it also has a great impact on driving safety. Common rain and sun protection devices include awnings, which include fixed and retractable awnings. The fixed type is more solid, but it cannot be folded, resulting in a larger overall size of the device. The retractable type can be folded to reduce the volume and reduce the impact on the driving process, but it has the disadvantage of a complex structure.

[0003] Among the existing patents, the patent with application number CN200720151742.X and publication date June 4, 2008 discloses a telescopic foldable car awning support frame, comprising two support rods and a cross bar fixedly connected between the two support rods, wherein the support rods are composed of multiple inserted telescopic rods. The telescopic rods are arc-shaped curved pipes with the same curvature, and a limiting meshing structure is arranged between the connecting end of the outer layer arc-shaped curved pipe and the sleeved section of the inner layer arc-shaped curved pipe. The meshing structure comprises an inner truncated cone surface having a large inner end diameter and a small outer end diameter arranged at the connecting end inside the outer layer arc-shaped curved pipe, and an outer truncated cone surface arranged at the sleeved end of the inner layer arc-shaped curved pipe and matching with the truncated cone surface of the connecting end inside the outer layer arc-shaped curved pipe. In addition, a locking groove can be arranged near the connecting end of the outer layer arc-shaped curved pipe, and a locking protrusion matching with the groove is formed at the sleeved end of the inner layer arc-shaped curved pipe, which is inserted into the locking groove when the car awning is unfolded. The telescopic structure in this patent is a sleeve type, which requires that the diameter of the extending tube is smaller than the storage tube, and there is a size limitation.

[0034] Return to reference Figure 1As shown in the figure, the main body 1 is connected to the supporting longitudinal rod 2, and the supporting longitudinal rod 2 includes a plurality of rods. The supporting longitudinal rod 2 is a long flat rod, and its length is the same when the number is 2, and is the same as the length of the storage part of the main body 1. The supporting longitudinal rods 2 are all arc rods, and the radius of curvature of the arc rods is the same as the radius of curvature of the storage part of the main body 1. The cross-sectional shape of the supporting longitudinal rod 2 is a rectangle with chamfers, and its area is slightly smaller than the size of the storage hole 5.1 in the storage part 5, and its width is smaller than the length while ensuring the support strength.

The canopy provided by the utility model can be connected to the canopy supporting piece 4 by sewing, and the canopy supporting piece 4 can change the supporting direction to provide support for the outer edge of the canopy.

[0036] Embodiment 1:

[0037] In this embodiment, the supporting longitudinal rods 2 include two supporting longitudinal rods 2, including a first supporting longitudinal rod 2.1 and a second supporting longitudinal rod 2.2.

The connecting piece 6B on the second supporting longitudinal rod 2.2 is closer to the main body 1 than the connecting piece 6A on the first supporting longitudinal rod 2.1. When the second supporting longitudinal rod 2.2 is extended to the limit, the connecting piece 6B on the second supporting longitudinal rod 2.2 contacts the connecting piece 6A on the first supporting longitudinal rod 2.1. At this time, the second supporting longitudinal rod 2.2 cannot continue to extend outward, preventing the second supporting longitudinal rod 2.2 from excessive movement. The contact surface of the two connecting pieces 6 is a plane, which improves the stability of the supporting structure when unfolded.

[0040] The size of the storage hole 5.1 in the storage member 5 connected to the main body 1 is related to the size of the connecting member 6. In this embodiment, the height and width of the storage hole 5.1 are the same as the height and width of the connecting member 6.

The two ends of the cloth used for shielding in the canopy are sewn on the canopy support sheet 4, and the supporting longitudinal rod 2 and the supporting cross bar 3 provide the main support for the cloth. The shielding area of ​​the canopy is the area enclosed by the supporting longitudinal rod 2 between the first supporting cross bar 3.1 and the third supporting cross bar 3.3. The cloth extension can be adjusted to the shielding direction by adjusting the direction of the canopy support sheet 4.

As shown in the figure, during the process of folding from the fully expanded state to the first folded state, the second supporting longitudinal rod 2.2 passes through the sliding connection hole 6.2 of the connecting member 6A until the fixing member contacts the connecting member 6A on the first supporting longitudinal rod 2.1. At this time, the third supporting cross bar 3.3 and the second supporting cross bar 3.2 are folded and overlapped, and the shielding area of ​​the awning is the area enclosed by the supporting longitudinal rod 2 between the first supporting cross bar 3.1 and the second supporting cross bar 3.2.
