[0044] The present invention will be further described below with reference to specific embodiments. These embodiments are intended only to illustrate the present invention and are not intended to limit its scope. The structural features of the present invention will now be described in detail with reference to the accompanying drawings. The wheelchair in this embodiment has a detachable sunshade structure that can be separably hidden within the wheelchair's structural units. Specially designed horizontal struts maximize the sunshade area, making assembly and disassembly more convenient and allowing for easy portability, thus enhancing the wheelchair's functional attributes.

[0045] Combine Figure 1 、 Figure 4 and Figure 5 It can be seen that this embodiment provides a wheelchair with a detachable sunshade structure, including a seat support part 1, a detachable sunshade structure 3 is provided above the seat support part 1, the rear end of the seat support part 1 is connected to a backrest support part 2, the top of the backrest support part 2 is provided with a height adjustment part 4, and the rear end of the sunshade structure 3 is connected to the height adjustment part 4.

[0046] The structure of the seat support part 1 is specifically composed of Figure 4 As shown in the figure, it includes a pair of side connecting tubes 11 arranged below the left and right sides of the seat cushion 6. The front ends of the side connecting tubes 11 are connected by front connecting tubes 12. The side connecting tubes 11 are arranged parallel to each other. The front connecting tubes 12 and the side connecting tubes 11 form a support frame for the seat cushion 6.

[0047] See further Figure 4 The structure of the backrest support part 2 is as follows: it includes a pair of support tubes 21 symmetrically connected to both sides of the backrest 7, the bottom of the support tubes 21 are connected by a bottom connecting plate 22, and a winding connecting cylinder 23 is connected between the support tubes 21. Figure 5 , the horizontal height of the side connecting pipe 11 is located between the bottom connecting plate 22 and the winding connecting cylinder 23; Figure 12 , the bottom connecting plate 22 and the side connecting pipe 11 are connected to the front and rear wheel frames 8.

[0048] See also Figure 8 The side wall of the support tube 21 is provided with an ear plate 231, and a pair of ear plates 231 are correspondingly provided. The two ends of the winding connecting tube 23 pass through the axial hole in the center of the ear plate 231, and the outer wall of the winding connecting tube 23 is connected to the axial hole in the center of the ear plate 231.

[0049] See also Figure 14 The sunshade structure 3 includes a sunshade cloth 31 and horizontal support rods 32 detachably connected to both sides of the sunshade cloth 31. Figure 2 The horizontal support rod 32 is connected to the height adjustment part 4 through the support rod connector 33. When the horizontal support rod 32 is connected to the height adjustment part 4, its projection in the vertical direction is located on the left and right sides of the side connection pipe 11. Figure 5 and Figure 6, the horizontal support rod 32 can be sleeved in the side connecting pipe 11 and the rear end opening of the side connecting pipe 11 is closed by the support rod connector 33; Figure 8 The sunshade cloth 31 is made of flexible sunshade material in the prior art. In this embodiment, the sunshade cloth 31 can be rolled up in the winding connecting cylinder 23. The winding connecting cylinder 23 is provided with at least one opening. A cap 232 is threadedly connected to the opening of the winding connecting cylinder 23. The cap 232 is designed to prevent the sunshade cloth 31 from falling out.

[0050] The wheelchair of this embodiment has a detachable sunshade structure, which can be hidden in the structural unit of the wheelchair in a detachable manner. The specially designed horizontal support rods 32 are used to maximize the sunshade area, making it easier to assemble and disassemble and can be carried lightly with the wheelchair, thereby improving the functional properties of the wheelchair.

[0051] The sunshade structure 3 of this embodiment is assembled in a simple manner. Its horizontal support rod 32 can be hidden in the side connecting tube 11 of the seat support part 1, and its sunshade cloth 31 can be folded or rolled up and hidden in the retracting connecting tube 23 of the backrest support part 2. The aforementioned side connecting tube 11 is a tubular supporting structure of the seat part in the wheelchair design, which plays the role of supporting the seat cushion 6 and connecting the front and rear wheel frames 8; the aforementioned retracting connecting tube 23 is a tubular connecting structure of the backrest part in the wheelchair design, such as Figure 4 In the figure, the reeling connecting tube 23 plays the role of reinforcing the overall firm structure of the backrest 7 and connecting the side connecting tube 11. This design aims to minimize the impact on the stable structure of the wheelchair, while utilizing the structural properties of the side connecting tube 11 and the reeling connecting tube 23 to conceal the horizontal support rod 32 and the sunshade cloth 31, so that the sunshade structure 3 is not only easy to assemble and disassemble, but also can be carried lightly with the wheelchair.

[0052] Specifically, when the sunshade structure is needed, the height of the height adjustment part 4 is adjusted according to different height requirements to set the horizontal height of the sunshade structure, the horizontal support rod 32 is connected to the front of the height adjustment part 4 through the support rod connector 33, and the sunshade cloth 31 is unfolded through the horizontal support rod 32. The sunshade cloth 31 can preferably be made of ultraviolet resistant materials in the existing technology, so that the sunshade structure can provide sunshade function and also has rain protection function to a certain extent; when the sunshade structure is not needed, see Figure 8 , remove the sunshade cloth 31 from between the horizontal support rods 32, fold and roll it into the rolling connecting cylinder 23, see Figure 5 and Figure 6 , remove the horizontal support rod 32 along with the support rod connector 33 from the height adjustment part 4, and then sleeve it into the side connecting tube 11. At the same time, the support rod connector 33 is detachably connected to the rear end opening of the side connecting tube 11, that is, the rear end opening of the side connecting tube 11 can be sealed by the support rod connector 33 to prevent the horizontal support rod 32 from falling out of the side connecting tube 11.

[0053] See also Figure 5 Combined with Figure 4 The seat support part 1 and the backrest support part 2 are connected in the following manner: a vertical connecting pipe 13 is provided at the top of the rear end of the side connecting pipe 11, a rearward-inclined curved pipe 131 is connected to the top of the vertical connecting pipe 13, and the top of the curved pipe 131 is connected to the winding connecting tube 23, which serves to connect the seat support part 1 and the backrest support part 2. Figure 5 and Figure 6 It can be seen that the structural combination of the vertical connecting tube 13 and the backward-inclined curved tube 131 allows sufficient space at the rear end of the side connecting tube 11 and above it, giving the accompanying strut connector 33 sufficient operating space when taking or preventing the horizontal strut 32. This improves the user experience and comfort of the product in terms of industrial design details.

[0054] See also Figure 14 The front edge of the sunshade cloth 31 is an arc, and there are through-holes 311 on the left and right sides. The horizontal support rods 32 pass through the through-holes 311. The through-holes 311 are formed by rolling up both sides of the sunshade cloth 31. The connection method of the horizontal support rods 32 through the through-holes 311 can be realized by the existing technology, so no further description will be given here.

[0055] See also Figure 1 and Figure 7 When the sunshade structure 3 is installed on the height adjustment part 4, the projection of the horizontal support rod 32 in the vertical direction is located on the left and right outsides of the side connecting tube 11, and the extension lines of the projection intersect at one point, which is equivalent to the horizontal support rods 32 of this embodiment being in an open state instead of being parallel to each other when used, and the front edge of the sunshade cloth 31 is designed as an arc to match it. By adopting such a structure, the projection area can be increased and the sunshade area can be increased.

[0056] Also, see Figure 9 The front end of the horizontal strut 32 is also connected to an extension rod 321, which can be extended or retracted within the horizontal strut 32. The extension rod 321 is retractable. The connection surface between the extension rod 321 and the horizontal strut 32 can be designed to have a certain friction, so that a certain amount of force is required to pull out or retract the extension rod 321. The extension rod 321 can also be preferably connected to the horizontal strut 32 via a threaded socket, so that the extension rod 321 can be rotated to rotate it out or retract it from the horizontal strut 32. The design structure of the extension rod 321 can extend the left and right sides of the sunshade cloth 31, further increasing the shielding area, while also not being limited by the length of the side connecting tube 11, which can only be designed with a rod structure with a length shorter than the side connecting tube 11.

[0057] In addition, in this embodiment, preferably, a sleeve or a binding rope is provided at the front end of the extension rod 321. The sleeve can preferably be threadedly connected to the front end of the extension rod 321 and its outer diameter is larger than the outer diameter of the through-hole 311, and is used to fix the front two corners of the sunshade cloth 31 to the front end of the extension rod 321, and to engage the connection between the extension rod 321 and the sunshade cloth 31 to prevent the sunshade cloth 31 from being blown away when the wind blows.

[0058] See also Figure 7 The structure of the height adjustment part 4 is as follows: it includes a pair of adjustment rods 41 sleeved in the support tube 21, the top of the adjustment rod 41 is connected by a top connecting rod 42, and the height adjustment part 4 is connected to the support tube 21. Figure 2 A support rod stopper 43 is provided near the top of the adjustment rod 41. The support rod connector 33 engages with the support rod stopper 43. A rotation stopper 44 is also threadedly connected to the top of the adjustment rod 41. The rotation stopper 44 can be rotated downward along the adjustment rod 41 until it is stopped on the outer wall of the support rod connector 33. When installing the support rod connector 33, first engage it with the support rod stopper 43 to position it, then rotate the rotation stopper 44 downward. The upper side wall of the rotation stopper 44 remains threadedly connected to the adjustment rod 41, while the lower side wall covers the support rod connector 33. This connection structure is quick to use and easy to assemble and disassemble.

[0059] See also Figure 6 The structure of the support rod connecting member 33 is as follows: it includes a clamping cylinder 331 and a threaded connecting rod 332 vertically connected thereto, Figure 5 The inner wall of the rear end of the side connecting tube 11 is provided with a thread, and the threaded connecting rod 332 can be threadedly connected to the side connecting tube 11. The front end of the threaded connecting rod 332 is connected to the horizontal support rod 32, and the rear end is connected to the bottom end of the side wall near the clamping cylinder 331. The side wall of the clamping cylinder 331 is provided with a vertical notch. The outer diameter of the clamping cylinder 331 is the same as the outer diameter of the adjusting rod 41; see Figure 15 The support rod limiting portion 43 includes a snap-fitting groove 431 embedded in the side wall of the adjusting rod 41, the snap-fitting cylinder 331 is adapted to the snap-fitting groove 431, and a threaded section 432 is provided at the top of the snap-fitting groove 431, and the threaded section 432 is threadedly connected to the aforementioned rotation limiting cylinder 44.

[0060] Combine Figure 15 In this embodiment, the connection method of the support rod connecting member 33, the support rod limiting portion 43 and the rotation limiting cylinder 44 is as follows: first, the clamping cylinder 331 of the support rod connecting member 33 is clamped in the clamping groove 431. After the clamping cylinder 331 is clamped with the clamping groove 431, the outer wall of the clamping cylinder 331 is flush with the outer wall of the adjusting rod 41. Then, Figure 2 In the process, the rotation limit cylinder 44 is rotated downward from the threaded section 432 until the bottom edge of the side wall of the rotation limit cylinder 44 contacts the threaded connecting rod 332. At this time, the upper side wall of the rotation limit cylinder 44 is still threadedly connected to the adjusting rod 41, and the lower side wall covers the locking cylinder 331.

[0061] For further information, see Figure 15 In this embodiment, the more reasonable structure of the horizontal support rod 32 can stably form an opening angle, combined with Figure 11 A positioning block 333 is provided at the bottom end of the side wall of the engaging cylinder 331, and a positioning ring 433 is provided at the bottom end of the engaging groove 431. The positioning ring 433 is fixedly connected to the adjusting rod 41, and a limiting groove 4331 adapted to the positioning block 333 is embedded in the positioning ring 433. The positioning block 333 engages with the limiting groove 4331. This design prevents the engaging cylinder 331 from rotating horizontally, thereby improving the stability of the horizontal support rod 32 during use.

[0062] See also Figure 1 、 Figure 7 and Figure 9 An adjusting mechanism 5 is provided at the connection between the support tube 21 and the height adjusting portion 4 , and the adjusting mechanism 5 serves to adjust the distance that the adjusting rod 41 extends from the support tube 21 .

[0063] See also Figure 13 、 Figure 16 、 Figure 17 and Figure 18 The structure of the adjustment mechanism 5 is specifically as follows: it includes a connecting ring 51 with a notch, a pair of wing plates 511 connected at the notch, and a rotating shaft 521 rotatably connected between the wing plates. The bottom end of the outer side of the rotating shaft 521 is connected to the adjusting plate 52. The bottom end of the side wall of the connecting ring 51 is connected to the top of the side wall of the support tube 21. An elastic bushing 55 is provided in the support tube 21. The top of the elastic bushing 55 is connected to a fastening pad 54 and a pair of elastic pads 53 through a connecting plate. The fastening pad 54 is located in the opening of the connecting ring 51 and is close to the side wall of the rotating shaft 521. The elastic pads 53 are symmetrically arranged on both sides of the fastening pad 54. Figure 17 and Figure 16 The elastic pad 53 is engaged with the top of the connecting ring 51, and the horizontal height of the fastening pad 54 is slightly lower than the elastic pad 53, because it needs to adapt to the top height of the rotating shaft 521. The projections of the elastic pad 53 and the fastening pad 54 on the vertical plane are both located in the same annular shape. Figure 3 and Figure 16 It can be seen that the adjusting rod 41 passes through the limited space formed by the elastic pad 53, the fastening pad 54 and the connecting ring 51. When the adjusting plate 52 is rotated downward to the lowest point, the rotating shaft 521 presses the fastening pad 54, so that the fastening pad 54 presses the side wall of the adjusting rod 41 to prevent the adjusting rod 41 from moving up and down.
