Sun umbrella
[0001] This disclosure claims priority to Chinese patent application No. CN2024118151813, filed on December 10, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This disclosure relates to a sunshade umbrella. Background Technology
[0003] Sun umbrellas are a common outdoor leisure product, used to block both sunlight and wind and rain. Currently, the canopy of sun umbrellas is usually fixed in position. However, the angle of sunlight varies at different times of day, and wind direction changes with the weather. A fixed canopy offers limited protection, significantly impacting the user experience. Some sun umbrellas incorporate adjustment mechanisms to improve canopy coverage. These mechanisms are often complex, increasing production costs and making the umbrella bulky. Furthermore, most adjustment mechanisms are cumbersome to operate and inconvenient to use. Public content
[0004] This disclosure provides a sunshade umbrella with a novel structure. The technical solution adopted is: a sunshade umbrella, including a top frame and a support rod for supporting the top frame, the support rod including:
[0005] The upper support rod is connected to the top frame, and the lower part of the upper support rod is provided with a first inclined surface having a first support point;
[0006] The lower support rod is located below the upper support rod. The lower part of the upper support rod is rotatably connected to the upper part of the lower support rod. The upper part of the lower support rod is provided with a second inclined surface, and the second inclined surface has a second support point and a third support point.
[0007] The support rod has a first mode and a second mode. In the first mode, the first support point and the second support point abut against each other, and the axis of the upper support rod is collinear or parallel to the axis of the lower support rod. In the second mode, the first support point and the third support point abut against each other, the height of the second support point is different from the height of the third support point, and the axis of the upper support rod intersects with the axis of the lower support rod.
[0008] In some embodiments, the upper support rod includes a first drive portion having the first support point, and the lower support rod includes a second drive portion having the second support point and the third support point. When the support rod switches between the first mode and the second mode, the first drive portion rotates relative to the second drive portion.
[0009] In some embodiments, the lower support rod has a rod body and a driving member. The lower part of the upper support rod is rotatably connected to the upper part of the rod body. The driving member is rotatably connected to the rod body about a rotation center line, which is collinear or parallel to the axis of the rod body. The upper part of the driving member is provided with a second inclined surface. By rotating the driving member, the first inclined surface and the second inclined surface are driven to slide relative to each other, thereby driving the upper support rod to rotate relative to the lower support rod, making operation more convenient.
[0010] In some embodiments, the support rod is in the first mode, with the drive member and the upper support rod extending along the same length direction, and the outer surface of the upper support rod smoothly connecting with the outer surface of the drive member. In the first mode, the support rod is more aesthetically pleasing.
[0011] In some embodiments, the top frame includes a top rod, a diagonal brace, and a slider. The top rod is rotatably connected to the upper support rod, the slider is slidably connected to the support rod, one end of the diagonal brace is rotatably connected to the top rod, and the other end of the diagonal brace is rotatably connected to the slider. The top frame has an unfolded state and a folded state. In the unfolded state, the top rod is unfolded relative to the upper support rod, and the slider is located within the segment range of the upper support rod. In the folded state, the support rod is in a first mode, the top rod is retracted relative to the support rod, the diagonal brace is retracted between the top rod and the support rod, and the slider is located within the segment range of the lower support rod. When the top frame switches between the unfolded state and the folded state, the support rod is in the first mode. When the support rod is in the first mode, the slider can slide between the upper and lower support rods.
[0012] In some embodiments, the rod body includes a first rod segment and a second rod segment, the second rod segment being fixedly disposed on the upper part of the first rod segment, the driving member being tubular, the lower part of the driving member being rotatably connected to the first rod segment, the second rod segment being located in the cavity of the driving member, and the lower part of the upper support rod being rotatably connected to the upper part of the second rod segment.
[0013] In some embodiments, the lower part of the upper support rod is provided with a connecting groove, and the upper part of the lower support rod is provided with a snap-fit part. The snap-fit part is slidably inserted into the connecting groove. The upper side wall of the connecting groove forms the first inclined surface, and the upper surface of the snap-fit part forms the second inclined surface. The connecting groove and the snap-fit part cooperate with each other to provide motion guidance for the relative sliding of the first and second inclined surfaces, making the mode switching of the support rod more stable.
[0014] In some embodiments, the connecting groove is annular, and the first inclined surface is annular; the snap-fit portion is annular, and the second inclined surface is annular. The larger contact area between the first and second inclined surfaces improves the stability of the lower support rod supporting the upper support rod, and further improves the stability of the support rod mode switching.
[0015] In some embodiments, the lower support rod has a rod body and a driving member. The driving member has a connecting portion and a lower fixed seat. The connecting portion is rotatably connected to the rod body about its axis. The lower fixed seat is fixed to the upper part of the connecting portion. The lower fixed seat has a first seat body and a second seat body. The first seat body has an arc-shaped first snap-fit structure, and the second seat body has an arc-shaped second snap-fit structure. The first seat body and the second seat body are radially connected to each other along the upper support rod. The first snap-fit structure and the second snap-fit structure are respectively inserted into the connecting groove. The first snap-fit structure and the second snap-fit structure are spliced together to form an annular snap-fit portion. The connection operation between the snap-fit portion and the connecting groove is simpler.
[0016] In some embodiments, the lower part of the upper support rod is rotatably connected to the upper part of the lower support rod.
[0017] In some embodiments, the lower support rod includes a rod body and a connecting seat, the connecting seat being rotatably connected to the upper part of the rod body about a first rotation center line, and the connecting seat being rotatably connected to the lower part of the upper support rod about a second rotation center line; the first rotation center line and the second rotation center line are perpendicular to each other.
[0018] In some embodiments, the first inclined surface is a plane, the second inclined surface is a plane, and when the support rod is in the first mode and the second mode, at least a portion of the first inclined surface and the second inclined surface are in contact. When the support rod switches between the first mode and the second mode, at least a portion of the first inclined surface and the second inclined surface are in contact. This improves the stability of the lower support rod supporting the upper support rod.
[0019] In some embodiments, when the support rod switches between the first mode and the second mode, at least a portion of the first inclined surface is in contact with the second inclined surface.
[0020] In some embodiments, the second inclined surface extends obliquely in the vertical direction; the first inclined surface extends obliquely in the vertical direction.
[0021] In some embodiments, the first inclined plane is annular; the second inclined plane is annular.
[0022] Due to the application of the above technical solution, this disclosure has the following advantages compared with the prior art: The sunshade of this disclosure can adjust the mode of the support rod by changing the abutment position of the first support point. Specifically, by the mutual abutment of the first inclined surface and the second inclined surface, while realizing the support function of the lower support rod on the upper support rod, the support position of the first support point is changed and the support height of the first support point is changed by driving the first inclined surface and the second inclined surface to slide relative to each other. This can drive the upper support rod to rotate relative to the lower support rod and change the included angle between the upper support rod and the lower support rod. During this process, the upper support rod drives the top frame to swing, thereby adjusting the shading angle of the sunshade. The structure of the sunshade is simpler and more adaptable.

[0036] The technical solutions of the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art. Obviously, the embodiments described in this disclosure are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0037] The following descriptions of directions, such as up, down, left, right, front, back, inside, and outside, are all based on the directions observed by the user when the parasol is in the unfolded state. They are intended only to facilitate the description of the relative positional relationships of the parasol's components and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this disclosure.
[0038] Referring to Figures 1 to 4, a sunshade includes a top frame 1 and a support rod 2 for supporting the top frame 1. The support rod 2 includes a lower support rod 21 and an upper support rod 22. The top frame 1 is connected to the upper support rod 22, and the lower support rod 21 is located below the upper support rod 22. The lower part of the upper support rod 22 is rotatably connected to the upper part of the lower support rod 21. The lower part of the upper support rod 22 has a first inclined surface 220 with a first support point 201. The upper part of the lower support rod 21 has a second inclined surface 230 with a second support point 202 and a third support point 203. The support rod 2 has a first mode and a second mode. In the first mode, the first support point 201 and the second support point 202 abut against each other, and the axis of the upper support rod 22 is collinear or parallel to the axis of the lower support rod 21. In the second mode, the first support point 201 and the third support point 203 abut against each other, the height of the second support point 202 is different from the height of the third support point 203, and the axis of the upper support rod 22 intersects the axis of the lower support rod 21. The aforementioned intersection of axis lines means that the projections of the axis of the upper support rod 22 and the axis of the lower support rod 21 in the vertical plane intersect at a point.
[0039] In this embodiment, the first inclined surface 220 of the upper support rod 22 and the second inclined surface 230 of the lower support rod 21 abut against each other, which not only supports the upper support rod 22, but also allows the second inclined surface 230 to extend obliquely in the vertical direction. By driving the first inclined surface 220 and the second inclined surface 230 to slide relative to each other, the support position and support height of the first support point are changed, which can drive the upper support rod 22 to rotate relative to the lower support rod 21 and drive the top frame 1 to swing. When the top frame 1 is unfolded relative to the support rod 2, by driving the first inclined surface 220 and the second inclined surface 230 to slide relative to each other, the support rod 2 can switch between the first mode and the second mode, thereby adjusting the shading angle of the sun umbrella so that it can block sunlight from different angles at different times, and also block wind and rain from different angles, making the sun umbrella more adaptable. In this embodiment, the first inclined surface 220 also extends inclinedly in the vertical direction, which can increase the contact area between the first inclined surface 220 and the second inclined surface 230, improve the stability of the lower support rod 21 supporting the upper support rod 22, and at the same time improve the sliding fit effect between the first inclined surface 220 and the second inclined surface 230.
[0040] In this embodiment, the upper support rod 22 includes a first driving part with a first support point 201, and the lower support rod 21 includes a second driving part with a second support point 202 and a third support point 203. When the support rod 2 switches between the first mode and the second mode, the first driving part rotates relative to the second driving part. Specifically, the lower support rod 21 has a rod body and a driving member 23. The upper part of the rod body is rotatably connected to the lower part of the upper support rod 22, and the driving member 23 is rotatably connected to the rod body around a rotation center line. The rotation center line and the axis of the rod body are collinear or parallel. The upper part of the driving member 23 is provided with the aforementioned second inclined surface 230. Specifically, in this embodiment, the rotation center line is the axis of the rod body. The rod body is used to connect with the upper support rod 22, and the driving member 23 is used to drive the support rod 2 to switch between the first mode and the second mode. Specifically, when the user drives the support rod 2 to switch between the first mode and the second mode, he only needs to drive the drive member 23 to rotate relative to the rod body, which can drive the first inclined surface 220 and the second inclined surface 230 to slide relative to each other, making the operation more convenient. At the same time, the user can also control the included angle between the upper support rod 22 and the lower support rod 21 more precisely by controlling the rotation angle of the drive member 23.
[0041] In this embodiment, the support rod 2 in the second mode has multiple states. Multiple third support points 203 are provided on the second inclined surface 230. When the first support point 201 abuts against different third support points 203, the state of the support rod 2 is different. Specifically, the support rod 2 in the second mode has an intermediate state and a limit state, as shown in Figure 3. In the limit state, there is a first angle between the upper support rod 22 and the lower support rod 21. The intermediate state is between the first mode and the limit state, as shown in Figure 2. In the intermediate state, the angle between the upper support rod 22 and the lower support rod 21 is greater than the first angle. In the limit state, the angle between the upper support rod 22 and the lower support rod 21 is the smallest, and the top frame 1 deflects at the largest angle compared to the first mode. In this embodiment, the upper support rod 22 can be rotated to any angle between the first included angle and the first mode by rotating the drive member 23. Specifically, by rotating the drive member 23, the included angle between the upper support rod 22 and the lower support rod 21 can be adjusted to any angle between 180 degrees and the first included angle, so that the top frame 1 has a variety of adjustable states.
[0042] In this embodiment, the lower part of the upper support rod 22 is rotatably connected to the upper part of the lower support rod 21. Specifically, referring to Figure 6, the lower support rod 21 also includes a connecting seat 211, which is rotatably connected to the rod body around the first rotation center line X1, and the connecting seat 211 is rotatably connected to the lower part of the upper support rod 22 around the second rotation center line X2; the first rotation center line X1, the second rotation center line X2, and the rotation center line are perpendicular to each other.
[0043] In this embodiment, the rod body includes a first rod segment 212 and a second rod segment 213, with the second rod segment 213 fixedly disposed on the upper part of the first rod segment 212. In this embodiment, the driving member 23 is tubular, with its lower part rotatably connected to the first rod segment 212 about a rotation center line. The second rod segment 213 is located within the tubular cavity of the driving member 23, and the lower part of the upper support rod 22 is rotatably connected to the upper part of the second rod segment 213. Specifically, the lower part of the second rod segment 213 is fixedly connected to the first rod segment 212 via a fixing pin 215, and the upper part of the second rod segment 213 is rotatably connected to the connecting seat 211 about a first rotation center line X1. This sleeved arrangement effectively controls the volume of the lower support rod 21 and facilitates user rotation of the driving member 23, thereby enabling convenient conversion of the support rod 2. In this embodiment, as shown in Figure 6, the upper part of the second rod segment 213 is provided with a mounting bracket 214. One end of the mounting bracket 214 is inserted into the rod cavity of the second rod segment 213 and is fixedly connected to the second rod segment 213. The other end of the mounting bracket 214 is rotatably connected to the connecting seat 211.
[0044] In this embodiment, the lower part of the upper support rod 22 is provided with a connecting groove 2221, and the upper part of the lower support rod 21 is provided with a snap-fit part 2320. The snap-fit part 2320 is inserted into the connecting groove 2221. The upper side wall of the connecting groove 2221 forms a first inclined surface 220, and the upper surface of the snap-fit part 2320 forms a second inclined surface 230. The connecting groove 2221 and the snap-fit part 2320 cooperate with each other, and the connection between the upper support rod 22 and the lower support rod 21 is improved by the snap-fit connection. The snap-fit connection also provides motion guidance for the relative sliding of the first inclined surface 220 and the second inclined surface 230, thereby improving the stability of the mode switching of the support rod 2. Specifically, as shown in Figures 8 to 11, the snap-fit part 2320 is provided on the upper part of the driving member 23, and the snap-fit part 2320 is slidably inserted into the connecting groove 2221. In this embodiment, the lower side wall of the connecting groove 2221 and the lower side surface of the snap-fit part 2320 opposite to the upper surface can also cooperate with each other and play the same role as the first inclined surface 220 and the second inclined surface 230.
[0045] In this embodiment, the connecting groove 2221 is located on the circumferential outer side of the upper support rod 22, and the opening of the connecting groove 2221 faces outward along the radial direction of the upper support rod 22. The locking part 2320 is inserted into the connecting groove 2221 from the outside to the inside. The locking part 2320 and the connecting groove 2221 cooperate with each other to limit the relative radial displacement between the upper support rod 22 and the lower support rod 21. In some embodiments, the opening of the connecting groove 2221 faces inward along the radial direction of the upper support rod 22, and the locking part 2320 is inserted into the connecting groove 2221 from the inside to the outside. The connecting groove 2221 and the locking part 2320 provide a guiding function while also serving a limiting function.
[0046] In some embodiments, the connecting groove 2221 is annular, providing a relatively slidable annular guide channel for the snap-fit portion 2320. In this embodiment, the connecting groove 2221 is annular, and the snap-fit portion 2320 is also annular. The upper wall of the connecting groove 2221 forms an annular first inclined surface 220, and the upper surface of the snap-fit portion 2320 forms an annular second inclined surface 230. The annular first inclined surface 220 and the second inclined surface 230 have a larger contact area in the first mode and the second mode, which improves the stability of the lower support rod 21 supporting the upper support rod 22. At the same time, during the mode conversion of the support rod 2, the first inclined surface 220 and the second inclined surface 230 with more area support each other and slide relative to each other, which further improves the stability of the mode conversion of the support rod 2. Specifically, the first inclined surface 220 is an annular ring extending around the axis of the upper support rod 22 and inclined in the vertical direction, and the second inclined surface 230 is an annular ring extending around the axis of the lower support rod 21 and inclined in the vertical direction.
[0047] In this embodiment, the connecting groove 2221 is arranged around the outer periphery of the upper support rod 22, and at least a portion of the driving member 23 is sleeved on the outer side of the connecting groove 2221, so that the annular snap-fit portion 2320 is inserted into the annular connecting groove 2221. Specifically, the driving member 23 has a connecting portion 231 and a lower fixing seat 232. The connecting portion 231 is rotatably connected to the rod body, and the lower fixing seat 232 is fixed on the upper part of the connecting portion 231. The second inclined surface 230 is provided on the upper part of the lower fixing seat 232. Referring to Figure 7, the lower fixing seat 232 has a first seat body 2321 and a second seat body 2322. The first seat body 2321 can be docked with the second seat body 2322. The first seat 2321 has an arc-shaped first snap-fit structure 2323, and the second seat 2322 has an arc-shaped second snap-fit structure 2324. When the first seat 2321 and the second seat 2322 are connected radially along the upper support rod 22, the first snap-fit structure 2323 and the second snap-fit structure 2324 are spliced together to form an annular snap-fit part 2320.
[0048] In this embodiment, at least one of the first base body 2321 and the second base body 2322 has a first positioning member 2325 on its outer side. The connecting part 231 is tubular, and the upper tube wall of the connecting part 231 has a first positioning groove 2311 with its opening facing upward. When connecting the lower support rod 21 and the upper support rod 22, the upper support rod 22 and the second rod segment 213 are first rotated and connected through the connecting seat 211. Then, the first base body 2321 and the second base body 2322 are aligned radially along the upper support rod 22, and the first snap-fit structure 2323 and the second snap-fit structure 2324 are both inserted into the connecting groove 2221, so that the snap-fit part 2320 and the connecting groove 2221 are connected simultaneously when the snap-fit part 2320 is spliced. Next, the connecting part 231 is fitted onto the outside of the second rod segment 213, and the assembled lower fixing seat 232 is inserted into the cavity of the connecting part 231, driving the first positioning member 2325 to be inserted into the first positioning groove 2311, completing the positioning between the lower fixing seat 232 and the connecting part 231, and preventing relative rotation between the lower fixing seat 232 and the connecting part 231. Then, the upper part of the first rod segment 212 is inserted into the cavity of the connecting part 231, realizing the rotational connection between the connecting part 231 and the first rod segment 212, and the first rod segment 212 and the second rod segment 213 are fixedly connected together by the fixing pin 215.
[0049] In this embodiment, the upper support rod 22 has a main body 221 and an upper fixed seat 222. The upper fixed seat 222 is fixedly mounted on the lower part of the main body 221. The lower part of the upper fixed seat 222 is provided with a connecting groove 2221, and the lower part of the upper fixed seat 222 is rotatably connected to the connecting seat 211 around the second rotation center line X2. Referring to Figure 5, the outer side of the upper fixed seat 222 is provided with a second positioning member 2222, and the main body 221 is provided with a second positioning groove 2211 with the opening facing downward. The upper fixed seat 222 is inserted into the rod cavity of the main body 221, and the second positioning member 2222 is inserted into the second positioning groove 2211. The positioning of the upper fixed seat 222 and the main body 221 is completed by the cooperation between the second positioning member 2222 and the second positioning groove 2211, and the relative rotation between the upper fixed seat 222 and the main body 221 can be restricted. The upper fixing seat 222 can be set on the lower support rod 21 and the lower fixing seat 232 can be set on the upper support rod 22, so that the upper part of the lower support rod 21 is provided with a connecting groove 2221 and the lower part of the upper support rod 22 is provided with a snap-fit part 2320.
[0050] In this embodiment, the first inclined surface 220 is a plane, and the second inclined surface 230 is a plane. Specifically, both the first inclined surface 220 and the second inclined surface 230 are annular planes. When the support rod 2 is in the first mode and the second mode, at least a portion of the first inclined surface and the second inclined surface are in contact, making the support of the lower support rod 21 on the upper support rod 22 more stable. When the support rod 2 switches between the first mode and the second mode, at least a portion of the first inclined surface and the second inclined surface are in contact and slide relative to each other, making the mode switching of the support rod 2 more stable.
[0051] In some embodiments, the first inclined surface 220 and the second inclined surface 230 are curved surfaces. In other embodiments, the first inclined surface 220 and the second inclined surface 230 are other shapes that allow the support height of the first support point to change during relative movement between them.
[0052] In some embodiments, multiple sets of first inclined surfaces 220 are provided, and the multiple sets of first inclined surfaces 220 are located in the same plane; or multiple sets of second inclined surfaces 230 are provided, and the multiple sets of second inclined surfaces 230 are located in the same plane.
[0053] In some embodiments, the upper part of the lower support rod 21 is provided with a third inclined surface. The second inclined surface 230 and the third inclined surface are not in the same plane. During the rotation of the driving member 23, the first inclined surface 220 disengages from the second inclined surface 230 and abuts against the third inclined surface. The first inclined surface 220 has a third support point, and the third inclined surface has a fourth support point and a fifth support point. The support rod 2 also has a third mode and a fourth mode. In the third mode, the third support point abuts against the fourth support point. In the fourth mode, the third support point abuts against the fifth support point. The heights of the fourth support point and the fifth support point are different, and the angle between the upper support rod 22 and the lower support rod 21 in the third mode is different from the angle between the upper and lower support rods 22 and the lower support rod 21 in the fourth mode. The aforementioned third support point is different from the third support point 203 on the second inclined surface. This third support point and the first support point can be the same support point, or they can be two different support points.
[0054] In this embodiment, the driving member 23 further includes an operating part 233, which is sleeved on the outside of the connecting part 231 and fixedly connected to the connecting part 231. The user can drive the driving member 23 to rotate by rotating the operating part 233. As shown in Figure 7, the outer side of the operating part 233 has multiple protruding ridges spaced apart. The extending direction of the protruding ridges is parallel to the axial direction of the lower support rod 21, which facilitates the user's rotation.
[0055] In this embodiment, in the first mode, the support rod 2 extends along the same length direction as the driving member 23 and the upper support rod 22, and the outer surface of the upper support rod 22 smoothly connects with the outer surface of the driving member 23. In the second mode, the extension direction of the upper support rod 22 forms an angle with the extension direction of the driving member 23.
[0056] In this embodiment, the top frame 1 can be unfolded and folded relative to the support rod 2. The top frame 1 includes a top rod 11, a diagonal brace 12, and a sliding member 13. The top rod 11 includes multiple spaced-apart members. The top rod 11 is rotatably connected to the upper support rod 22, and the sliding member 13 is slidably connected to the support rod 2. One end of the diagonal brace 12 is rotatably connected to the top rod 11, and the other end of the diagonal brace 12 is rotatably connected to the sliding member 13. The top frame 1 has an unfolded state and a folded state. In the unfolded state, the top rod 11 is unfolded relative to the upper support rod 22, the sliding member 13 is located within the segment range of the upper support rod 22, and the diagonal brace 12 is supported between the top rod 11 and the sliding member 13. In the folded state, the support rod 2 is in a first mode, the top rod 11 is folded relative to the upper support rod 22 and the lower support rod 21, the diagonal brace 12 is folded between the top rod 11 and the support rod 2, and the sliding member 13 is located within the segment range of the lower support rod 21. When the top frame 1 is switched between the unfolded state and the folded state, the support rod 2 is in the first mode, and the slider 13 can slide between the upper support rod 22 and the lower support rod 21.
[0057] In some embodiments, the sunshade is provided with an operating mechanism for controlling the unfolding and folding of the top frame 1. The operating mechanism includes a rope 3, one end of which is connected to a slider 13. The rope 3 pulls the slider 13 to slide along the support rod 2, thereby driving the top frame 1 to unfold or fold relative to the support rod 2. This is more convenient than manually driving the slider 13 to slide. In this embodiment, the connecting seat 211 has a cavity that runs vertically through the roof. The rod cavity of the first rod segment 212, the rod cavity of the second rod segment 213, the cavity of the connecting seat 211, and the rod cavity of the upper support rod 22 are interconnected, forming a channel that runs vertically through the roof. The rope 3 can be placed in this channel to avoid mutual interference between the rope 3 and other components, thereby ensuring that the mode switching of the support rod 2 and the unfolding and folding of the top frame 1 can be performed normally.
[0058] In summary, the sunshade of this embodiment, through the mutual abutment of the first inclined surface 220 and the second inclined surface 230, not only achieves the supporting function of the lower support rod 21 on the upper support rod 22, but also changes the supporting position and height of the first support point 201 by driving the first inclined surface 220 and the second inclined surface 230 to slide relative to each other. This drives the upper support rod 22 to rotate relative to the lower support rod 21 and changes the angle between the upper support rod 22 and the lower support rod 21. During this process, the upper support rod 22 drives the top frame 1 to swing, thereby adjusting the shading angle of the sunshade. The structure of the sunshade is simpler and more adaptable.
