When the sunshade component 4 is used, the end of the sunshade component 4 is connected to the upper end of the support rod 3. A sunshade device is added to the rear side of the wheelchair. When in use, the sunshade component 4 can be pulled out and supported by the support rod 3 to block the sunlight for the patient, which solves the defect that the current wheelchair does not have a sunshade function, brings convenience to the patient, and increases the comfort of using the wheelchair in summer. At the same time, it also has a rain shelter function. When it rains outdoors, the sunshade component 4 can also be used to block the rain to prevent the patient from catching a cold. When not in use, the sunshade component 4 is stored in the sunshade box 6, and the sunshade box 6 is arranged at the rear end of the backrest 5, does not take up too much space, and realizes the rational use of the idle space on the rear side of the wheelchair.
[0037] like Figure 6 As shown, the sunshade box 6 is provided with a storage cavity 604 inside, and both sides of the storage cavity 604 are provided with a slide hole 601 with an upper opening, and the slide hole 601 is a cylindrical hole, and one side of the slide hole 601 is connected to the storage cavity 604, as shown in FIG. Figure 5 As shown, the upper end surface of the sunshade box 6 is provided with a cloth outlet hole 603, which is a rectangular long hole, and the cloth outlet hole 603 is connected with the sliding hole 601 and the storage cavity 604 respectively. The sunshade component 4 includes a connecting rod 401, a sunshade cloth 402, a sliding rod 403, and a limiting rod 404. The sunshade cloth 402 is made of polyester fabric and has a dark color to increase the effect of sun protection and ultraviolet blocking. Figure 7 As shown, both sides of the sunshade cloth 402 are connected with sliding rods 403, and the length of the sliding rods 403 is greater than the length of the sunshade cloth 402, which can support and fix the lower end of the sunshade cloth 402, so that the sunshade cloth 402 has a certain wind resistance and increases the firmness and stability during use. The sliding rods 403 are made of aluminum alloy, glass fiber or carbon fiber, and are similar to tent poles and can be bent for support. Sliding rods are set on both sides of the sunshade cloth 402, which can not only support the sunshade cloth 402, but also increase the convenience of pulling and storing, and ensure the smooth pulling and drawing process.
[0038] like Figure 7As shown, the upper end of the sunshade cloth 402 is connected with a connecting rod 401, which is a quadrangular prism rod. Two sliding rods 403 are connected by the connecting rod 401. The connecting rod 4041 can protect the upper end of the sunshade cloth 402 to prevent damage, and is convenient for pulling, connecting and fixing.
[0039] like Figure 7 As shown, the lower end of the sunshade cloth 402 is provided with a limiting rod 404, the two ends of the limiting rod 404 are connected to the sliding rod 403, the width of the cloth outlet hole 603 is smaller than the width of the storage cavity 604, the width of the limiting rod 404 is larger than the width of the cloth outlet hole 603 and smaller than the width of the storage cavity 604, the sunshade cloth 402 is arranged in the storage cavity 604, the sunshade cloth 402 cooperates with the cloth outlet hole 603, the sliding rod 403 cooperates with the sliding hole 601, and the connecting rod 401 is arranged at the upper end of the sunshade box 6. It can prevent excessive pulling during use and avoid pulling out the sunshade cloth 402 completely. The limiting rod 404 also has a pull-down function, which can ensure that the sunshade cloth 402 is flat in the length direction during use. When storing, under the pulling of the limiting rod 404, the storage is smoother, and the sunshade cloth 402 is prevented from bending and wrinkling in the storage cavity 604.
[0040] like Figure 5 As shown, the upper end surface of the sunshade box 6 is provided with a fixing hole 602. Figure 8 As shown, the lower end surface of the connecting rod 401 is provided with a plug post 406, and the plug post 406 cooperates with the fixing hole 602. The number of the fixing hole 602 and the plug post 406 are both multiple. Through the cooperation of the plug post 406 and the fixing hole 602, the connecting rod 401 can be fixed when the sunshade cloth 402 is not in use. The fixing method is simple and firm, and it is easy to open in time and convenient to use; the lower end surface of the sunshade box 6 is provided with a vent hole, and the vent hole is connected with the storage cavity 604. The storage cavity 604 can be ventilated to prevent the sunshade cloth 402 from getting wet. At the same time, after being rained, it is easy to remove rainwater in time and accelerate the drying speed inside the storage cavity 604.
[0041] like Figure 8 As shown, connecting holes 407 are provided at both ends of one side of the connecting rod 401, and a connecting piece 405 is provided in the connecting hole 407. A socket 301 is provided on the upper end surface of the support rod 3, and a cylindrical cavity is provided inside the upper end of the support rod 3.

[0042] The connecting member 405 includes a connecting column 408 and a stopper 409. The connecting column 408 is a cylindrical structure, and the stopper 409 is a quadrangular column structure. One end of the connecting column 408 is connected to the middle of one side of the stopper 409, and the other end of the connecting column 408 is connected to the bottom end of the connecting hole 407. Fig. 9 As shown, the shape of the plug hole 301 is rectangular and matches the shape of the stopper 409 .
[0043] When in use, first, pull the connecting rod 401 to pull the sunshade cloth 402 out of the sunshade box 6, and bend the sliding rod 403 so that the connecting rod 401 is set at the upper end of the front support leg 1, and then pull the support rod 3 out of the front support leg 1, so that the upper end of the support rod 3 is inserted into the connecting hole 407. When plugging, the stopper 409 is aligned with the plug hole 301, as shown in FIG. Figure 4 As shown, after inserting the connecting piece 401 into the cavity of the support rod 3, rotate the support rod 3, the rotation angle is 90°, at this time, the connecting rod 401 is firmly connected to the support rod 3 under the action of the stopper 409, and then adjust the height of the support rod 3. After adjusting the appropriate height, tighten the locking bolt 101, and the locking bolt 101 will firmly fix the lower end of the support rod 3. At this time, the sunshade cloth 402 can provide shade and shelter for the patient. After use, first loosen the locking bolt 101, and then rotate the support rod 3 to disengage the connecting piece 401 from the support rod 3, and then store the support rod 3 in the rod storage hole 102, push the sunshade cloth 402 into the sunshade box 6, and make the plug column 406 on the connecting rod 401 cooperate with the fixing hole 602 on the sunshade box 6 to complete the storage process. At this time, the state is as follows: Fig.10 shown.
[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
