Description
Technical Field
[0001] This application relates to the field of awning technology, and more specifically to an adjustable pivot arm for an awning support. Background Technology
[0002] A motorhome is a mobile transportation vehicle that combines the functions of a "house" and a "vehicle," figuratively called a "home on wheels." A sunshade is installed on the side of the motorhome. Normally, the sunshade is folded; it unfolds when needed to provide shade outdoors. The sunshade consists of a sunshade curtain and a sunshade frame, which is the structure fixedly mounted on the vehicle body.
[0003] There is a type of awning bracket, such as Figure 7 As shown, the device includes a fixed frame 94, a swing arm frame 95, a roller blind frame 96, a gas spring 97, and a pivot 98. The fixed frame 94 has a receiving groove. One end of the swing arm frame 95 and the pivot 98 extends into the receiving groove and is rotatably connected to the fixed frame 94. The roller blind frame 96 is rotatably connected to the other end of the swing arm frame 95 and the pivot 98. Both ends of the gas spring 97 are rotatably connected to the swing arm frame 95 and the pivot 98, respectively. A roller blind is rotatably mounted on the roller blind frame 96. Under normal conditions, the swing arm frame 95... The boom 95, the roller blind 96, the gas spring 97, and the pivot 98 are all placed in the receiving groove. However, since the length of the pivot 98 is fixed, the preload of the boom 95 in the folded state is constant at a certain value. As RVs are highly personalized, users have different requirements for the force and speed at which the awning bracket is deployed. Some users want the boom 95 to deploy more quickly at the beginning, while others want it to deploy more slowly at the beginning.
[0004] Therefore, there is a need for an adjustable pivot arm for a sunshade bracket with a finely adjustable pivot length and a finely adjustable initial deployment speed of the swing arm. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.
[0032] An illustrative example of an adjustable pivot arm for a sunshade bracket, see reference. Figures 1 to 6 An adjustable pivot arm for a sunshade bracket according to any preferred embodiment of the present invention is provided on the sunshade bracket. The adjustable pivot arm for the sunshade bracket includes a pivot assembly 10 and a first fastener 20.
[0033] Specifically, in any embodiment of this application, such as Figures 1 to 3 As shown, the pivot assembly 10 includes a first rod 101, a second rod 102, and a sliding rod 103. The first rod 101 has a first groove 1011, and the second rod 102 has a second groove 1012. The second rod 102 is slidably disposed on the first rod 101, and the bottom wall of the second groove 1012 covers the opening of the first groove 1011. The sliding rod 103 passes through the side wall of the second groove 1012 and is fixedly connected to the second rod 102. The side wall of the first groove 1011 has a sliding hole 10111, and the sliding rod 103 slidably passes through the sliding hole 10111. In addition, the first fastener 20 is screwed to fix the position of the sliding rod 103 in the sliding hole 10111.
[0034] Additionally, in any embodiment of this application, such as Figure 4 As shown, the awning support also includes a fixed frame 90, a swing arm frame 91, a roller blind frame 92, and a gas spring 93. The fixed frame 90 has a receiving groove 901. One end of the swing arm frame 91 and the first rod 101 extends into the receiving groove 901 and is rotatably connected to the fixed frame 90. The roller blind frame 92 is rotatably connected to both the swing arm frame 91 and the second rod 102. Both ends of the gas spring 93 are rotatably connected to the swing arm frame 91 and the first rod 101, respectively. A roller blind is rotatably mounted on the roller blind frame 92.
[0035] It should be noted that the two ends of the fixing frame 90 are fixed to the vehicle body by bolts. One end of the roller blind is connected to the vehicle body. The sum of the length of the swing arm frame 91 and the length of the roller blind frame 92 is greater than the sum of the lengths of the first rod 101, the second rod 102 and the fixing frame 90. Under normal conditions, the swing arm frame 91, the roller blind frame 92, the gas spring 93 and the pivot assembly 10 are all placed inside the fixing frame 90. When the roller blind frame 92 is partially close to the receiving groove 901 of the fixing frame 90, that is, when part of the roller blind frame 92 is located at the opening of the receiving groove 901, there is an initial force under the elastic force of the gas spring 93. This initial force gives the roller blind frame 92 the power to unfold when unfolding, and also generates a resistance when folding the roller blind frame 92, that is, when the roller blind frame 92 is completely submerged in the receiving groove 901. If the user is not accustomed to this initial force, that is, feels uncomfortable when unfolding or folding the roller blind frame 92, the first fastener 20 can be tightened to allow the sliding rod 103 to slide along the sliding hole 10111. When the sliding rod 103 slides, the overall length of the pivot assembly 10 increases or decreases. It should also be emphasized that the fixing frame 90 is made of aluminum, which is relatively soft and easily deformed under stress. The maximum extension or reduction stroke of the second rod 102 relative to the first rod 101 is between 3mm and 10mm, depending on the hardness of the aluminum material. Since both the swing arm frame 91 and the roller blind frame 92 are hinged to the pivot assembly 10, and the swing arm... Since the overall length of the frame 91 and the roller shutter frame 92 remains unchanged, the fixed frame 90 will bend slightly after being subjected to force. That is, the area near the pivot assembly 10 where the fixed frame 90 is rotatably connected to the pivot assembly 10 will be concave or convex to compensate for the slight extension or shortening of the pivot assembly 10. Since the pivot assembly 10 is rotatably connected to the gas spring 93, the extension length of the gas spring 93 will also change slightly when it is close to closing, and provide a slight change in damping to meet the user's tactile needs. The change in damping also causes a change in the initial pop-out speed. It is evident that, compared with the prior art, this application has the advantage of being able to finely adjust the pivot length and finely adjust the initial unfolding speed of the swing arm frame 91.
[0036] Furthermore, in the first embodiment of this application, to realize a screw-on first fastener 20 for fixing the sliding rod 103 in the sliding hole 10111, such as Figure 2As shown, the sliding rod 103 has an extension 1031 on its side wall. The adjustable pivot arm of the sunshade bracket also includes a connecting rod 30. One end of the connecting rod 30 is fixedly connected to the extension 1031. The bottom wall of the second groove 1012 has a stepped slide groove 10121. The end of the connecting rod 30 away from the extension 1031 passes through the stepped slide groove 10121. The side wall of the end of the connecting rod 30 away from the extension 1031 fits against the side wall of the stepped slide groove 10121 with a smaller width dimension. The end of the connecting rod 30 away from the extension 1031 is threadedly connected to the first fastener 20. When the first fastener 20 rotates at a predetermined angle, the bottom surface of the first fastener 20 abuts against or separates from the bottom wall of the stepped slide groove 10121 with a larger width dimension.
[0037] It should be noted that when the bottom surface of the first fastener 20 abuts against the bottom wall of the stepped slide groove 10121 at the end with the larger width dimension, the position of the connecting rod 30 within the sliding hole 10111 is determined under the action of frictional resistance. Since the sliding rod 103 is fixedly connected to the second rod 102, the position of the second rod 102 relative to the first rod 101 is fixed. When it is necessary to adjust the relative position of the second rod 102 and the first rod 101, the first fastener 20 is screwed on and the bottom surface of the first fastener 20 is separated from the bottom wall of the stepped slide groove 10121 at the end with the larger width dimension. At this time, the first rod 101 and the second rod 102 can slide relative to each other, and the first fastener 20 is tightened after sliding to the designated position.
[0038] Furthermore, for ease of installation, in the first embodiment of this application, as... Figure 2 As shown, the extension portion 1031 and the connecting rod 30 are designed separately. Specifically, one side of the extension portion 1031 has a first threaded hole 10311, and one end of the connecting rod 30 is threadedly connected to the first threaded hole 10311. A thread-bonded adhesive layer is provided between the connecting rod 30 and the first threaded hole 10311. It should be noted that the thread-bonded adhesive layer is applied to the surface of the first threaded hole 10311 before the connecting rod 30 is threaded into it. This thread-bonded adhesive layer strengthens the connection between the extension portion 1031 and the connecting rod 30.
[0039] The figure illustrates a second embodiment of this application, in which, as shown in the figure... Figure 5As shown, the sliding rod 30 has an abutment plane 301 and an anti-rotation plane 302 on both sides, respectively. The abutment plane 301 and the anti-rotation plane 302 are respectively in contact with the two side walls of the sliding hole 10111. The bottom wall of the second groove 1012 has a stepped hole 10122, and one end of the stepped hole 10122 with a smaller diameter has a thread. The first fastener 20 is threaded to one end of the stepped hole 10122 with a smaller diameter, and the first fastener 20 abuts against or separates from the abutment plane 301.
[0040] It should be noted that, in the second embodiment, the relative sliding between the second rod 102 and the first rod 101 is limited by the friction between the first fastener 20 and the abutment plane 301. When the end face of the first fastener 20 separates from the abutment plane 301, the second rod 102 and the first rod 101 can slide relative to each other. After sliding to a specified position, the relative position of the second rod 102 and the first rod 101 is fixed by having the first fastener 20 abut against the abutment plane 301.
[0041] Furthermore, since the adjustable pivot arm of the sunshade bracket is used on the vehicle body, to improve safety, the relative positions of the first rod 101 and the second rod 102 need to be doubly locked. Specifically, in any embodiment of this application, such as Figure 2 and Figure 3 As shown, the sliding rod 103 has a through second threaded hole 1032 at its center. The adjustable pivot arm of the sunshade bracket also includes a second fastener 40, which is threadedly connected to the second threaded hole 1032. One end of the second fastener 40 abuts against or separates from the side wall of the first groove 1011.
[0042] It should be noted that when the second rod 102 slides relative to the first rod 101, in addition to loosening the first fastener 20, the second fastener 40 also needs to be loosened. Conversely, to fix the relative position of the second rod 102 and the first rod 101, both the first fastener 20 and the second fastener 40 need to be tightened. Furthermore, it is readily apparent that the tightening directions of the first fastener 20 and the second fastener 40 are perpendicular to each other.
[0043] It should also be noted that, since the pivot assembly 10 is placed within the receiving groove 901 when the awning bracket is folded, to avoid interference between the second fastener 40 and the side wall of the receiving groove 901, the second fastener 40 is concealed within the sliding rod 103. Specifically, in any embodiment of this application, such as Figure 3As shown, when one end of the second fastener 40 abuts against the side wall of the first groove 1011, the other end of the second fastener 40 is flush with one side wall of the second rod 102.
[0044] Furthermore, in any embodiment of this application, to facilitate circumferential rotation of the second fastener 40, such as... Figure 6 As shown, one end of the second threaded hole 1032 has an enlarged portion 10321, and one end of the second fastener 40 has a strip groove 401. A screwing plate 402 is slidably disposed in the strip groove 401. When the screwing plate 402 rotates circumferentially, the other end of the second fastener 40 abuts against or separates from the side wall of the first groove 1011.
[0045] It should be noted that, under normal circumstances, the screwing plate 402 is placed inside the second fastener 40. When it is necessary to screw the second fastener 40, the screwing plate 402 can be pulled out and rotated to drive the second fastener 40 to rotate circumferentially.
[0046] Furthermore, in any embodiment of this application, to place the screwing plate 402 within the second fastener 40 and to prevent the screwing plate 402 from disengaging from the strip groove 401, such as... Figure 6 As shown, the adjustable pivot arm of the sunshade bracket also includes an elastic element 403, the two ends of which abut against the two ends of the screw plate 402 and the strip groove 401, respectively.
[0047] In summary, the adjustable pivot arm for the awning bracket described in the embodiments of this application is explained, which provides advantages such as fine adjustment of the pivot length and fine adjustment of the initial deployment speed of the swing arm frame.
[0048] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
