[0023] In order to explain the technical solution disclosed by the utility model in detail, a further introduction is given below in conjunction with the accompanying drawings of the specification.

[0024] Figure 1 The utility model shows a sunshade that can be fixed on the outer surface of a building, and is more often used on one side of a motorhome to form a cool activity area. The sunshade is fixed to one side of the motorhome through a fixing frame 300, and then the extension of the arm 100 is controlled by a driving device 400, so that the sunshade cloth 200 can be opened or closed. The sunshade arm mounting base provided by the utility model is located at Figure 1 At A in the figure, the enlarged structure is as follows Figure 2 shown.

[0025] The awning arm mounting base described in the utility model can be found in Figure 3 The structure shown includes a base body 1, which is used to be fixed on the side of the RV or on a fixing frame. The base body 1 is provided with a double screw structure, including an upper screw 2 and a lower screw 3. It should be noted that the upper screw 2 is located in a waist-shaped groove 101 opened in the base body 1, which can be seen in FIG. Figure 4As shown, the lower screw 3 is located in the cylindrical hole 103 opened in the base body 1 and can be combined Figure 6 As shown. At the ends of the upper screw 2 and the lower screw 3, that is, at the ends of the openings of the base body 1, a sealing gasket or a sealing rubber ring 9 is provided to achieve sealing and waterproofing. Both ends of the upper screw 2 and the lower screw 3 are threaded structures and are fixed to the base body 1 through nuts 401 or connected to the fixing bolts 8 on the arm insert 4. The other end of the arm insert 4 is provided with a rotating shaft 10, and the arm 5 is fixed on both sides of the rotating shaft 10, so that the rotation of the arm 5 can be realized, and the stretching movement as shown in Figure 1 can be achieved.

[0026] Furthermore, as shown in combination with Figure 5 and Figure 6 , the utility model is provided with a double-screw structure on the base body 1. The lower screw 3 is fixed in the cylindrical hole 103 adapted to it, playing a stable supporting connection role. When the upper screw 2 is installed, it is also directly fixed through the waist-shaped groove 101 and the nuts at both ends, and the installation process ensures that its fixing frame is horizontal. As the sunshade cloth unfolds, due to the gravity of the front bumper, including the actual installation process and application considerations, the sunshade awning will tilt forward and downward. The downward tilt is because there are accessories such as support rods in the sunshade awning. When the hanging point is relatively high, it is necessary to open and tilt a certain distance to be able to reach the support rod (front bumper) by hand, which is convenient for operation, but the positions of the fixing frame and the like are relatively high. Therefore, according to different vehicle models and installation heights, set screws are also needed to adjust and limit the downward tilt angle.

[0027] For an undeployed awning, horizontal installation is more aesthetically pleasing, so the fixing frame is fixed in a straight line, and the base body 1 is also set to fit the side of the RV. For example, the technology disclosed in the prior art awning arm (CN220849061U) also uses a waist-shaped groove, but in actual application, it is found that when the sunshade cloth is unfolded, it will suddenly rotate in the waist-shaped groove when it is close to or has reached the maximum extension area, and the sound of the parts in the waist-shaped groove snapping into place can be heard, and there is a problem that the downward tilt angle cannot be adjusted after installation. In this regard, the base provided by the utility model is provided with two independent double-screw structures to solve this downward tilt setting. The lower screw 3 achieves stability. The upper screw 2 can be used to adjust and slowly control its rotation in the waist-shaped groove. The spring assembly 6 is arranged by opening a hole on the base body 1, so that it can contact the upper screw rod 2 through the hole. The upper screw rod 2 is fixed with a stop rod 102 at the position of the hole. A compression spring 601 is sleeved on the stop rod 2. The bottom of the compression spring 601 is against the root of the stop rod 102, and the other end is against the inside of the compression spring cover 602. The compression spring cover 602 is fixed to the base body 1 by threads. The compression spring cover 602 can be controlled by the threads to move downward close to the surface of the base body 1, which corresponds to the compression deformation of the compression spring 601 under force, and the resistance and force on the stop rod 102 are increased. Therefore, the position of the upper screw rod 2 in the waist-shaped groove 101 can be controlled by the compression spring cover 602, which can alleviate the suddenness of the movement of the upper screw rod 2 in the waist-shaped groove 101 and avoid the occurrence of the impact sound when it is locked into place. Furthermore, for the installed awning, when it is found that the downward tilt angle does not meet the requirements, it can be adjusted through the downward tilt adjusting bolt 7. The bottom end of the downward tilt adjusting bolt 7 is in contact with the upper screw rod 2, including being set to an arc surface to fit the surface of the upper screw rod 2. By turning the downward tilt adjusting bolt 7, the upper screw rod 2 is pressed downward, causing the upper screw rod 2 to move to other positions in the waist-shaped groove 101. By changing the position of the upper screw rod 2, the arm plug-in 4 connected thereto will also tilt, which will be reflected by the arm 5 also tilting downward or upward, thereby changing the downward tilt angle of the sunshade cloth on the arm 5.

[0028] It is additionally explained that, during the initial installation, the lower screw rod 3 is fixed by a nut and cannot rotate due to friction and the like. The upper screw rod 2 in the waist-shaped groove 101 can be adjusted and fixed in place during the initial installation. However, with the use and repeated extension of the awning, the lower screw rod 3 will inevitably move, that is, there will be a certain amount of rotational clearance, but it will not affect normal use. In this case, the compression spring assembly 6 and the downward tilt adjustment bolt 7 provided on the upper screw rod 2 play a role in adjustment. In addition, in the structure described in the utility model, the lower screw rod 3 can avoid the loss caused by overcoming friction and can increase the service life of the awning.
