DETAILED DESCRIPTION

[0028] Reference Figure 1-11 As shown, the arm seat adjustment structure includes an arm seat 1, a crank arm assembly 2 installed on the arm seat 1, a deflection assembly and a limit assembly are arranged in the arm seat 1, the crank arm assembly 2 is rotatably arranged on the deflection assembly, and the limit assembly is used to control the maximum deflection angle of the deflection assembly.

[0029] like Figure 1 The figure shows a stereoscopic view of a crank arm awning, in which a motor for driving the awning cloth to extend is arranged inside the awning casing. When the awning cloth is unfolded, the spring 14 inside the crank arm assembly 2 is released to control the crank arm assembly 2 to open. When the crank arm assembly 2 is fully opened, the crank arm assembly 2 is deflected under the influence of the weight of the extended end of the crank arm assembly 2.

[0030] Among them, Figure 3 As shown, this figure is an exploded view, in the arm base 1, a first section 3 for installing the deflection assembly and a second section 4 for installing the limit assembly are provided, the first section 3 is circular, the second is bar-shaped, the second section 4 is connected to the first section 3 and is located below the first section 3.

[0031] The deflection assembly includes an arm seat shaft 5 embedded in the first section 3, the rear end of the arm seat shaft 5 is located at the outer end of the arm seat 1, the crank arm assembly 2 is rotatably arranged at the rear end of the arm seat 1, the middle part of the arm seat shaft 5 is hollow, and a first arc groove 6 connecting the middle hollow area is arranged on the arm seat shaft 5 and at the bottom, the limit assembly is located below the first arc groove 6, and moves within the arc range of the first arc groove 6, and a first slider 7 and a second slider 8 are movably arranged in the axial direction of the central area of ​​the arm seat shaft 5, the first slider 7 is located at the front end of the first section 3, and the second slider 8 is located at the rear end of the first section 3, the second slider 8 is connected to the crank arm assembly 2 through a connecting rod 9, one end of the connecting rod 9 is hinged in the second slider 8, and the other end is hinged to the crank arm assembly 2.

[0032] In addition, in order to prevent the first slider 7 from making abnormal noise when in contact with the second slider 8 , a rubber layer is provided on the second slider 8 and at the contact surface of the first slider 7 .

[0033] like Figure 3-8 As shown, the first arc groove 6 passes through the arm seat rotating shaft 5, and an arc block 10 is provided on the first slider 7 and is located in the first arc groove 6. The length of the arc block 10 is consistent with the length of the first slider 7 and is smaller than the length of the first arc groove 6. The first arc block 10 partially blocks the first arc groove 6, and the remaining area of ​​the first arc groove 6 matches the limiting component.

[0034] like Figure 9-11 As shown, when the awning is opened, the crank arm assembly 2 rotates with the rotation point of the arm seat 1 as a fulcrum, and the crank arm assembly 2 pulls the second sliding block 8 to move toward the crank arm assembly 2 through the connecting rod 9.

[0035] like Figure 4-8 As shown, the limit assembly includes an adjusting bolt 11 which passes through the second interval 4 horizontally and vertically, and an adjusting block 12 with a width smaller than that of the second interval 4 is arranged on the adjusting bolt 11 and located in the second interval 4. The top of the adjusting block is arranged in an arc shape and is located in the first arc groove 6. When the adjusting bolt 11 is rotated, the adjusting block 12 is controlled to move forward and backward in the second interval 4 according to the rotation direction. After the crank arm assembly 2 is opened, it is used to limit the arm seat shaft 5 from abutting when it deflects to prevent it from continuing to rotate.

[0036] In order to ensure that the position of the adjusting bolt 11 does not move, the part on the adjusting bolt 11 that cooperates with the arm seat 1 is the optical axis, and the rest is the normal part with threads. In this way, when the adjusting bolt 11 is rotated, the main body of the adjusting bolt 11 will only rotate but not move, and the adjusting block 12 can move on the adjusting bolt 11 under the action of the threads.

[0037] A spring groove 13 is provided in the middle of the first slider 7 and at the other end face of the second slider 8, and a cover 17 is provided on this end face. A spring 14 is provided in the spring groove 13 and rests on the cover 17. The spring 14 is in a force storage state in the initial state. Through the action force of the spring 14, the first slider 7 always has the action force to contact the second slider 8.

[0038] In order to further ensure that the arm seat shaft 5 does not rotate excessively, a fixed limit block 15 is provided on the inner top surface of the arm seat 1 , and a second arc groove 16 is provided on the upper part of the arm seat shaft 5 , and the fixed limit block 15 is located in the second arc groove 16 .

[0039] The position of the adjusting block 11 in the second section 4 is located behind the arc block 10 .

[0040] like Figure 3 As shown, an arc rib 19 is transversely arranged in the middle of the connecting seat 18, and connecting holes located above and below the arc rib 19 are arranged on the cover 17, the arm seat shaft 5, and the connecting seat 18. The three are fastened together by setting a bolt. In actual application, since the length of the crank arm assembly 2 is relatively long, the weight of the crank arm assembly 2 will cause the end of the crank arm assembly 2 away from the connecting seat 18 to be in a slightly hanging state. At this time, the arc rib 19 can be used as a fulcrum, the bolts located above the arc rib 19 can be tightened, and the bolts located below the arc rib can be slightly loosened, so that the end of the crank arm assembly 2 away from the connecting seat 18 is tilted to avoid hanging.

[0041] When the adjusting nut 11 is not rotated: in the initial state, Figure 4 As shown, in the initial state, the adjustment block 12 is located at the rightmost side of the second interval 4. At this time, the arm base shaft 5 and the arc block 10 on the first slider 7 are shown in the figure, which means that the awning cloth has the smallest inclination angle. In the initial state, the internal state of the arm base shaft 5 is as shown in the figure. Figure 8As shown, when the motor is started and the awning is controlled to be unfolded, the crank arm assembly 2 extends outward, and the second slider 8 is pulled toward the crank arm assembly 2 by the connecting rod 9. Since the spring 14 is in a force storage state in the initial state, when the second slider 8 moves, the first slider 7 is always kept in contact with the second slider 8 under the action of the spring 14. During the movement of the first slider 7, the arc block 10 on the first slider 7 will not collide with the adjustment block 12. When the crank arm assembly 2 following the awning is unfolded, it is affected by the gravity of the front edge of the awning, and the arm seat shaft 5 will rotate clockwise, and the first slider 7 moves from the front end of the first section 3 to the rear end. Figure 5 As shown, the right side arc wall of the first arc groove 6 contacts the adjusting block 12 to limit the rotation of the arm seat shaft 5. When the motor controls the tarpaulin to be retracted, the first slider 7 and the second slider 8 are reset.

[0042] like Figure 6 As shown, in Figure 5 In this state, the adjusting bolt 11 is rotated to adjust the adjusting block 12 to be located in the middle position of the second section 4, the arm seat shaft 5 rotates, the right arc edge of the first arc groove 6 is always close to the top arc edge of the adjusting block 12, and the arc block 10 on the first slider 7 is located at the rear end of the second section 4.

[0043] In this state, when the tarpaulin on the awning is retracted, the crank arm assembly 2 re-squeezes the second slider 7 and the first slider 8 through the connecting rod 9, and the spring 14 is compressed again. At this time, the adjustment block 12 moves from the rear end of the second section 4 to the front end. At this time, the gravity on the front end of the tarpaulin is reduced, and the arm seat shaft 5 is deflected and reset again.

[0044] In such Figure 8 As shown in the figure, the adjusting bolt 11 has been adjusted. When the motor is started here to control the tarpaulin to be unfolded, similarly, the second slider 8 is pulled toward the direction of the crank arm assembly 2 by the connecting rod 9. The first slider 7 is restricted by the adjusting block 12 and cannot move with the second slider 8. The second slider 8 is away from the first slider 7. Before the tarpaulin is fully opened, the arm seat shaft 5 is deflected by the drooping force at the front end of the tarpaulin. The arm seat shaft 5 controls the first slider 7 and the second slider 8 to rotate synchronously. The adjusting block 12 no longer blocks the arc block 10. At this time, the arm seat 1 is restored to the state as shown in the figure. Figure 6As shown in , when the awning is retracted, the crank arm assembly 2 re-compresses the second slider 8 and the first slider 7 through the connecting rod 9, and the spring 14 is compressed again. At this time, the adjustment block 12 moves from the rear end to the front end of the second section 4. At this time, the gravity on the front end of the awning is reduced, and the arm seat shaft 5 is deflected and reset again, and the initial state of the arm seat shaft 5 is restored as shown in FIG. Figure 7 Shown

[0045] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
