DETAILED DESCRIPTION OF THE INVENTION

[0027] Preferred examples of the disclosure will be described in detail below in combination with accompanying drawings, such that advantages and features of the disclosure can be more readily understood by those skilled in the art, thereby defining the protection scope of the disclosure clearer.

[0028] A principle of adjusting tightness of an awning tarpaulin 4 is as follows: one end of a torsional spring body 8 is kept to be fixed to a reel 5 while the other end of the torsional spring body is kept to be fixed to a main shaft 7. The main shaft 7 rotates to drive one end, fixedly connected to the main shaft, of the torsional spring body 8 to rotate, such that resilience of the torsional spring body 8 is increased or decreased, thus implementing tightness adjustment.

[0029] According to an awning mechanism in the prior art, a supporting arm 91 is fixedly connected to the main shaft 7 extending out of an end cover 6, and one end of the supporting arm 91 away from the end cover 6 is fixedly connected to an expansion bin 2 by means of a detachable polygonal extension rod 12. In this way, the awning tarpaulin 4 may be unwound and kept in a tight state after the expansion bin 2 is opened.

[0030] As the resilience of the torsional spring body 8 changes after long-term use and the awning tarpaulin 4 is exceedingly loose, a rebounding torsion force of a torsional spring needs to be adjusted to ensure that the awning tarpaulin may be completely closed after wound. In a case of adjusting the tightness, a worker needs to hold the supporting arm 91 with one hand, pull the polygonal extension rod 12 out of the supporting arm 91 with the other hand, and disassembles the supporting arm 91 from the expansion bin 2, such that one end, connected to the main shaft 7, of the supporting arm 91 is in a rotatable state, and a disassembly process is laborious. Meanwhile, when the polygonal extension rod 12 is pulled out, the torsion force of the torsional spring body 8 in the reel 5 is very large. In a case of a hand slip, the resilience of the spring is instantly released, it is likely to hit the hand and cause accidental injury.

[0031] In order to solve the problems, with reference to FIGS. 2-5, the disclosure provides an externally-adjustable awning mechanism free of disassembly. The awning mechanism includes a reel 5 internally hollowed, and further includes at least one main shaft 7 horizontally located in the reel 5, a torsional spring body 8 and a locking assembly 9. The locking assembly 9 includes a supporting arm 91 rotatably connected to the main shaft 7. One end of the main shaft 7 sequentially extends out of the reel 5 and a surface of the supporting arm 91 and is capable of being locked to the supporting arm 91 by means of a locking member. The other end of the main shaft is rotatably connected to the reel 5. It should be noted that the supporting arm 91 is vertically arranged, and one end, not connected to the main shaft 7, of the supporting arm is fixed on the recreational vehicle.

[0032] The torsional spring body 8 is arranged on a periphery of the main shaft 7 in a sleeving manner. One end of the torsional spring body is fixedly connected to one end of the main shaft 7 close to the supporting arm 91. The other end of the torsional spring body is fixedly connected to an inner wall of the reel 5. One end of the main shaft 7 close to the supporting arm 91 is provided with several penetrating torsional spring fixing holes 71, such that the torsional spring body 8 is fixed.

[0033] The awning tarpaulin 4 is pulled and unwound to drive the reel 5 to rotate synchronously, and one end, fixedly connected to the reel 5, of the torsional spring body 8 generates a spring torsion force under rotation and is in an open state. When the awning tarpaulin 4 needs to be wound, the torsional spring body 8 drives the awning tarpaulin 4 to be wound automatically under the action of the spring torsion force.

[0034] When the torsion force of the torsional spring body 8 needs to be adjusted, the awning tarpaulin 4 is adjusted to a wound state. In this case, the awning tarpaulin 4 and a tarpaulin track 3 are just in a tightened state, and the locking member configured to lock the supporting arm 91 and the main shaft 7 is pulled out. Then, the main shaft 7 may rotate relative to the supporting arm 91, and the entire main shaft 7 and the torsional spring body 8 on the main shaft may be rotated only by clockwise or counterclockwise rotating part of the main shaft 7 extending out of the supporting arm 91. In the rotation process, a counter-acting force relative to the torsional spring body 8 is formed just with tension of the awning tarpaulin 4, and the torsion force of the torsional spring body 8 is adjusted by combining the tightness of the awning tarpaulin. After the tightness is determined, the locking member is inserted into the corresponding locking insertion holes 72 on the supporting arm 91 and the main shaft 7, and the torsion force of the torsional spring body 8 is adjusted.

[0035] It should be noted that in the adjustment process, the torsion force of the torsional spring can be adjusted without disassembling the supporting arm 91, such that both time and labor are saved. Meanwhile, the supporting arm 91 cannot swing left and right under the action of the torsion force of the torsional spring, so as to avoid harm to a human body.

[0036] A hexagonal nut 10 is fixedly arranged at one end of the main shaft 7 extending out of the supporting arm 91. Specifically, in some examples, the hexagonal nut 10 is fixed to the main shaft by means of an elastic pin. It should be noted that a fixing method between the hexagonal nut and the main shaft is not limited, as long as the main shaft may rotate while the hexagonal nut is rotated.

[0037] The awning mechanism further includes an adjusting assembly 13 detachably connected to the hexagonal nut 10. The adjusting assembly 13 includes an adjusting round handle 131 and an adjusting hexagonal recess. The adjusting hexagonal recess is matched with the hexagonal nut 10 in shape. When a torsion force of the torsional spring body 8 is adjusted, the hexagonal nut 10 is sleeved with the adjusting round handle 131, and then rotating adjustment is conducted. Thus, rotating adjustment of the main shaft 7 is faster and more convenient, and is more labor-saving than direct rotation of the main shaft 7 with a human hand.

[0038] In some examples, a periphery of the adjusting round handle 131 is provided with a plurality of notches convenient for workers to hold. A part, connected to the periphery, of each of the notches is provided with a chamfer of greater than 2 mm. A surface of the entire adjusting round handle 131 is smooth and has no sharp edges and corners. In a case of accidentally releasing the handle, compared with a case of rotating the supporting arm 91, no harm to the human body can be ensured. With reference to optimal grip strength of ordinary adults, a diameter is set as 75 mm. A number of the notches is specifically set as 6, such that hand slips can be effectively avoided.

[0039] An end of one side of the main shaft 7 close to the supporting arm 91 is provided with several locking insertion holes 72. The supporting arm 91 includes a locking part 93 and a fixing part 94 arranged from top to bottom. A limiting hole corresponding to the locking insertion holes 72 is provided on one side of the locking part 93 close to the main shaft 7. When the main shaft 7 needs to be locked to the supporting arm 91, only the locking member needs to be inserted into the limiting hole and the locking insertion holes 72. When the torsion force of the torsional spring body 8 needs to be adjusted, the main shaft 7 may be rotated by pulling out the locking member. Thus, operation is simple and quick.

[0040] Specifically, several locking insertion holes 72 are spaced in a length direction of the main shaft 7, and a circumference of the main shaft 7 is further provided with several locking insertion holes 72, such that torsion adjustment of different rotation angles is satisfied.

[0041] The locking member is a B-shaped pin 92. When the B-shaped pin 92 is inserted into the locking insertion holes 72 and the limiting hole, an upper horizontal surface on the B-shaped pin abuts against an abutting surface 95 of the locking part 93. It is ensured that the main shaft 7 is incapable of rotating relative to the supporting arm 91 after the B-shaped pin 92 positions the supporting arm 91 and the main shaft 7. Stability of torsion adjustment of the torsional spring body 8 is ensured.

[0042] One side of the supporting arm 91 away from the main shaft 7 is horizontally provided with an accommodation recess 96 configured to accommodate the hexagonal nut 10. The accommodation recess 96 is provided with a detachable decorative cover 14. The accommodation recess 96 is capable of protecting the hexagonal nut 10, such that the hexagonal nut is prevented from rusting after being used for a long time. The decorative cover 14 is arranged to protect the hexagonal nut 10 and also make the entire mechanism more attractive.

[0043] One end, not fixed to the main shaft 7, of the torsional spring body 8 is fixedly connected to the inner wall of the reel 5 by means of a torsional spring limiting block 11.

[0044] In some examples, two main shafts 7 are sequentially arranged in a horizontal direction. The main shafts 7, the torsional spring body 8, the locking assembly 9 and the adjusting assembly 13 are all symmetrically arranged along a center line of the reel 5. One ends of the two main shafts 7 away from each other may extend out of two supporting arms 91 at two ends of the reel 5 respectively. Thus, the awning tarpaulin 4 is more stable to wind or unwind.

[0045] The two ends of the reel 5 are each fixedly provided with one end cover 6. When the main shaft 7 extends out of the reel 5, the main shaft firstly penetrates the end cover 6 on the reel 5, and the end cover 6 and the torsional spring limiting block 11 cooperate with each other, so as to support the entire main shaft 7.

[0046] One side of the end cover 6 close to the reel 5 is provided with a plurality of rivet holes in a spaced manner along the periphery. A rivet is inserted into each of the rivet holes correspondingly, so as to fix the reel 5 to the end cover 6. In this way, the torsional spring body 8, the main shaft 7 and other structures in the reel 5 are protected.

[0047] Two sides of the end cover 6 are each provided with one soundproofing pad, so as to reduce friction noise between the end cover 6 and the supporting arm 91.

[0048] In some other examples, only one main shaft 7 may be provided. One end of the main shaft extends out of the reel 5 and the surface of the supporting arm 91, and the other end of the main shaft is rotatably connected to the reel 5. Winding and unwinding of the awning tarpaulin 4 cannot be influenced. In this case, one end of the reel 5 away from the supporting arm 91 may be provided with the end cover 6 or the torsional spring limiting block 11.

[0049] With reference to FIG. 1, a recreational vehicle includes any one of the awning mechanisms, and further includes a recreational vehicle compartment 1 and an expansion bin 2 capable of sliding out of a surface of one side of the recreational vehicle compartment 1. The expansion bin 2 is slidably connected to the recreational vehicle compartment by means of a rack track arranged in a width direction of the recreational vehicle compartment 1.

[0050] A supporting arm 91 further includes a fixing part 94 located at a lower portion. The fixing part 94 is detachably connected to the expansion bin 2 by means of a connecting assembly. When the expansion bin 2 slides out of the recreational vehicle compartment 1, the reel 5 rotates while the awning tarpaulin 4 is unwound, and one end, fixedly connected to the reel 5, of the torsional spring body 8 rotates to generate a spring torsion force. When the awning tarpaulin needs to be wound, the expansion bin 2 is moved back to the recreational vehicle compartment 1, such that the tarpaulin may be automatically retracted under the action of the spring torsion force.

[0051] The connecting assembly includes a mounting support 15 arranged on a top of an external wall of the expansion bin 2 and a polygonal extension rod 12 horizontally inserted into the mounting support 15. One end of the polygonal extension rod 12 close to the supporting arm 91 extends into a limiting recess on the fixing part 94.

[0052] In some examples, the polygonal extension rod 12 is a hexagonal extension rod, and the limiting recess is matched with the hexagonal extension rod in shape. When the hexagonal extension rod is inserted into the limiting recess, the supporting arm 91 cannot rotate and thus is vertically arranged more stably.

[0053] It should be noted that the mounting support 15 is provided with a hexagonal through slot which is configured to allow the hexagonal extension rod to be inserted into and matched with the hexagonal extension rod in shape.

[0054] A top of the recreational vehicle compartment is provided with a tarpaulin track 3 configured to fix one end of an awning tarpaulin 4. Two sides of the awning tarpaulin 4 are provided with lines. The lines are mounted in the tarpaulin track 3 so as to fix and tighten the awning tarpaulin. The other end of the awning tarpaulin 4 is fixedly wound around a reel. The reel is also provided with an awning tarpaulin fixing groove. A fixing method is to fix the other end of the awning tarpaulin by enabling the lines provided on the awning tarpaulin to penetrate the fixing groove, such that the awning tarpaulin is conveniently wound around the reel.

The content cannot limit the protection scope of the disclosure. All equivalent changes or modifications made according to the spirit of the disclosure should fall within the protection scope of the disclosure.
