DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6The utility model provides a wheelchair sunshade device, comprising a backboard 1 and a wheelchair body 2 for mounting the backboard 1, the backboard 1 being arranged on the back of the wheelchair body 2, a detachable mounting assembly being arranged between the backrest of the wheelchair body 2 and the backboard 1, the backboard 1 being mounted on the backrest of the wheelchair body 2 through the detachable mounting assembly, the detachable mounting assembly comprising mounting plates 11 fixedly mounted on both sides of the backboard 1, positioning hooks 12 being arranged on both upper and lower sides of the front of the mounting plate 11, connecting plates 13 being fixedly mounted on the inner sides of the two sets of positioning hooks 12, an elastic connecting assembly being arranged between the connecting plate 13 and the mounting plate 11, the connecting plate 13 being connected to the mounting plate 11 through the elastic connecting assembly The plate 11 is movably installed, and the upper and lower sides of the backrest of the wheelchair body 2 are both arranged in an arc shape. The positioning hooks 12 are arranged in an arc shape that matches the backrest of the wheelchair body 2, and the hooks of the two groups of positioning hooks 12 are respectively fitted with the upper and lower sides of the backrest of the wheelchair body 2. The elastic connection component includes a fixing groove 14 opened on the surface of the mounting plate 11, and the inner cavity of the fixing groove 14 is slidably connected with a slider 15. One side of the slider 15 passes through the fixing groove 14 and extends to the outside of the fixing groove 14 and is fixedly connected to the back side of the connecting plate 13. A compression spring 16 is fixedly installed on the top of the slider 15, and the end of the compression spring 16 away from the slider 15 is fixedly connected to the inner wall of the fixing groove 14.

[0027] By setting up the detachable installation component, the sunshade component in the present device can be installed on the backrest of the existing wheelchair body 2. During installation, the user can pull the two groups of positioning hooks 12 to the upper and lower sides respectively. The movement of the positioning hooks 12 will squeeze the compression springs 16 through the connecting plate 13 and the slider 15. Then the user can move the two groups of positioning hooks 12 to the upper and lower sides of the backrest of the wheelchair body 2 and release the positioning hooks 12. At this time, the reaction force generated by the squeezing of the compression springs 16 will respectively clamp the two groups of positioning hooks 12 on the upper and lower sides of the backrest of the wheelchair body 2 to install and fix the use position of the sunshade component and the foldable connecting component.

[0028] Preferably, a limiting assembly is arranged between the two sides of the slider 15 and the inner wall of the fixed groove 14, and the limiting assembly includes limiting blocks 17 fixedly installed on both sides of the slider 15, and limiting grooves 18 corresponding to the limiting blocks 17 are opened on both sides of the inner cavity of the fixed groove 14, and the surface of the limiting block 17 is slidably connected to the inner wall of the limiting groove 18.

[0029] By setting the limiting component, the slider 15 can be limited to prevent the slider 15 from slipping out of the inner cavity of the fixing groove 14 during the sliding process. When the slider 15 moves, it will drive the limiting blocks 17 on both sides thereof to slide in the inner cavity of the limiting groove 18.

[0030] Among them, a sunshade assembly is arranged above the wheelchair body 2, the sunshade assembly is foldable, and the use angle of the sunshade assembly is adjustable. The sunshade assembly includes a sunshade cloth 3 arranged above the wheelchair body 2, and a top rod 4 and a sliding rod 5 are respectively installed on both sides of the sunshade cloth 3. Connecting rods 6 are installed on the other two sides of the sunshade cloth 3, and both ends of the connecting rod 6 are fixedly connected to the inner sides of the top rod 4 and the sliding rod 5 respectively.

[0031] In this embodiment, the sunshade assembly is based on a sunshade cloth 3, which is surrounded by two groups of connecting rods 6, a group of top rods 4 and a group of sliding rods 5, which are spliced ​​into a rectangle to fix the four sides of the sunshade cloth 3 so that the sunshade cloth 3 can be opened to provide shade.

[0032] It is worth mentioning that a foldable connecting assembly is arranged between the sunshade assembly and the back panel 1, and the sunshade assembly is movably installed together with the back side of the back panel 1 through the foldable connecting assembly. The foldable connecting assembly includes two sets of slide rails 7 fixedly installed on the back side of the back panel 1, and the two ends of the sliding rod 5 are respectively slidably connected to the inner cavities of the two sets of slide rails 7. The top ends of the two sets of slide rails 7 are provided with positioning grooves 10 adapted to the top rod 4, and the bottoms of the two ends of the top rod 4 are respectively fitted with the corresponding inner walls of the positioning grooves 10.

[0033] By setting up the foldable connecting component, the sunshade cloth 3 can be easily folded and stored. When folding and storing it, the user can loosen the positioning rod 9 and then flip the sunshade cloth 3 so that the top rod 4 and the sliding rod 5 are respectively located on the upper and lower sides of the sunshade cloth 3. Then the user can move the top rod 4 downward so that the two ends of the sliding rod 5 slide in the inner cavity of the slide rail 7. After the two ends of the top rod 4 are inserted into the inner cavity of the positioning groove 10, the sunshade cloth 3 stops moving. At this time, the sunshade assembly is folded and stored on the back of the backrest of the wheelchair body 2.

[0034] Furthermore, an angle positioning assembly for positioning the use angle of the sunshade cloth 3 is installed at the top of one side of the slide rail 7. The angle positioning assembly includes a positioning tube 8 fixedly installed on one side of the slide rail 7. One end of the positioning tube 8 is threadedly connected to a positioning rod 9. One end of the positioning rod 9 passes through the positioning tube 8 and the slide rail 7 in sequence and extends to the inner cavity of the slide rail 7 to fit with the surface of the sliding rod 5.

[0035] Through the setting of the angle positioning component, after adjusting the use angle of the sunshade cloth 3, the user can tighten the positioning rod 9. The rotation of the positioning rod 9 will cause one end of the positioning rod 9 to pass through the positioning tube 8 and the slide rail 7 in sequence and extend to the inner cavity of the slide rail 7 to fit with the surface of the sliding rod 5, thereby locking and positioning the use angle of the sunshade cloth 3.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
