Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of awnings for recreational vehicles, in particular to an awning capable of preventing fabric wrinkles. Background Art
[0002] The expansion compartment installed on the RV is pulled out during camping to increase the usable space of the RV. The expansion compartment is shielded by a sunshade between the expansion compartment and the RV body.
[0003] The existing awning lock cloth strip is fixed on the RV, one end of the fabric is fixed to the lock cloth strip, and the other end is fixed to the roll tube, and then rolled on the roll tube. There is a torsion spring inside the roll tube to give the fabric a tensile force to roll up. The roll tube is fixed to the expansion compartment of the RV. When the expansion compartment is opened, the lock cloth strip is fixed to the RV and does not move, and the expansion awning moves with the expansion compartment. At this time, the roll tube rotates, and the fabric unfolds as the expansion compartment opens. When the expansion compartment is closed, the roll tube rotates in the opposite direction due to the torsion of the spring inside the roll tube, and the fabric is rolled up and retracted.
[0004] Since the two ends of the expansion awning's reel tube are fixed and in a fixed position, and the expansion awning usually lacks a mechanism that relies on the reel tube or the mechanism that relies on the reel tube is fixed. When the expansion awning is unfolded, the thickness of the fabric on the reel tube decreases, and at the same time, the tension of the torsion spring on the fabric increases, resulting in a lack of effective support in the middle of the reel tube and an arc-shaped deformation. When the awning is rolled up, the fabric wrinkles, affecting the opening and closing of the awning, and even causing it to get stuck. Utility Model Content

[0030] The specific implementation of the utility model of an anti-fabric wrinkle awning is described in detail below with reference to the accompanying drawings.
[0031] See attached Figure 1-4 The awning is arranged between the RV 1 and the expansion warehouse 2, including a locking cloth strip 3 arranged on the RV 1 and an end cover 4 arranged on the outside of the expansion warehouse 2. The locking cloth strip 3 fixes one end of the awning tarpaulin 5. A card slot is arranged on the locking cloth strip 3, and one end of the tarpaulin 5 is clamped in the card slot through a rubber strip.
[0032] There are two end covers 4, each of which is provided with a pipe plug 6, a reel 7 is sleeved on the pipe plug 6, the other end of the awning tarpaulin 5 is fixed on the reel 7, a slot is also provided on the reel 7, and the other end of the tarpaulin 5 is also clamped in the slot through a rubber strip.
[0033] A cover is provided outside the end cover 4 and the coiling tube 7. The cover is composed of two parts, namely an upper cover 8 and a lower cover 9. A mounting code 10 is provided below the cover. The mounting code 10 is fixed on the side wall of the expansion chamber 2. The mounting code 10 fixes the end cover 4 and the coiling tube 7 in the cover. A decorative cover 11 is provided on the end cover 4 to protect the end cover 4.
[0034] A torsion spring assembly 12 is arranged inside the reel 7 , and the torsion spring assembly 12 enables the reel 7 to generate a reeling force on the tarpaulin 5 . The length of the reel 7 is less than the distance between the two end covers 4 .
[0035] See attached Figure 5 The torsion spring assembly 12 includes a torsion spring rod 13 and a torsion spring 14. A waist-shaped hole 17 is provided on the end cover 4. A slider 16 is provided in the end cover 4. One end of the slider 16 fits in the waist-shaped hole 17. The torsion spring rod 13 is fixed at the center of the other end of the slider 16. The torsion spring 14 is sleeved on the torsion spring rod 13. One end of the torsion spring 14 is fixed on the torsion spring rod 13, and the other end is fixed on the positioning member 15. The positioning member 15 is slidably matched with the reel 7. When the reel 7 rotates, the positioning member 15 causes the torsion spring 14 to generate a torsion force on the reel 7. There are two torsion spring assemblies 12, which are respectively provided at both ends of the end cover 4, and the two torsion spring assemblies 12 are symmetrically provided.
[0036] See attached Figure 1 , 2 When camping in the RV 1, the expansion chamber 2 is opened from the RV 1. When it is opened, the awning tarpaulin 5 is pulled out from the reel 7. When the tarpaulin 5 is pulled out, the reel 7 is pulled and rotated. As the tarpaulin 5 at the reel 7 is pulled away, the diameter of the reel 7 wrapped with the tarpaulin 5 gradually decreases, so that the reel 7 will move toward the expansion chamber due to the slider 16 along the waist-shaped hole 17 of the end cover 4. During the entire unfolding process, the lower cover 9 always relies on the reel 7 to prevent its horizontal deformation, so as to prevent the tarpaulin fabric from deforming. When the expansion chamber 2 is closed, the tarpaulin 5 between the expansion chamber 2 and the RV 1 is relaxed, the tension of the torsion spring 14 is reduced, the deformation of the torsion spring 14 is restored, and the reel 7 rotates to reel in the tarpaulin 5. As the number of turns of the rolled tarpaulin 5 increases, the diameter of the tarpaulin fabric on the rolling tube 7 increases. At this time, due to the support of the lower cover shell 9, the rolling tube 7 will move away from the expansion warehouse 2 along the waist-shaped hole 17 of the end cover 4 due to the slider 16. During the entire process of the expansion warehouse 2 being retracted into the RV 1, the lower cover shell 9 always relies on the tarpaulin fabric on the rolling tube 7 to prevent its horizontal deformation, so as to prevent the fabric from deforming.
[0037] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
