Description

Technical Field

[0001] The utility model relates to the technical field of electric wheelchairs, in particular to a storm-resistant wheelchair for use in both sunny and rainy weather. Background Art

[0002] With the increasing aging population and the growing travel needs of disabled groups, electric wheelchairs are designed as an electric personal mobility tool for the elderly and disabled groups. They are powered by electricity and are designed to help people with limited mobility move more easily and independently indoors and outdoors, improving their quality of life and autonomy.

[0003] The electric wheelchairs currently on the market have obvious shortcomings when it comes to coping with travel scenarios such as sun protection on sunny days or rain protection: when using an umbrella, users need to hold the umbrella handle with one hand and operate the wheelchair control switch with the other hand. This operation method not only forces the user to be distracted and reduces the convenience of travel, but also when operating with one hand, the other hand cannot hold the armrest, which may bring potential safety hazards and greatly affect the user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a storm-resistant wheelchair for both sunny and rainy days, so as to solve the problem that the user needs to hold the umbrella handle with one hand when using the existing electric wheelchair to protect against sunburn on sunny days or to protect against rain on rainy days.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The yoke is provided with a plurality of supporting plates, and the supporting plates are hinged on the top of the supporting plates, and the upper ends of the supporting plates are provided with armrests. A controller is installed on the upper surface of the armrests, a connecting plate is installed on the lower surface of the base, and a lifting assembly is provided on the upper surface of the connecting plate. The lifting assembly includes a shell, which is installed on the upper surface of the connecting plate, and the inner surface of the shell is rotatably connected to the first rotating shaft. The outer surface of the first rotating shaft is provided with a first gear and a first transmission wheel. The inner surface of the shell is provided with a slide groove, and the inner surface of the slide groove is slidably connected to the first rack, and a clamping block is installed at one end of the first rack, which is meshed with the first gear, and the inner surface of the clamping block is clamped with an electric umbrella.

[0007] Furthermore, the inner surface of the shell is also rotatably connected to a second rotating shaft, the outer surface of the second rotating shaft is installed with a second transmission wheel, the second transmission wheel is connected to the first transmission wheel through a belt, a first motor is installed inside the base, the output shaft of the first motor is connected to the second rotating shaft through a coupling, and a cover plate is clamped on the upper surface of the shell.

[0008] Furthermore, an electric push rod is installed inside the base, and an output end of the electric push rod passes through the base and is installed with an abutment plate.

[0009] Furthermore, an installation groove is provided on the outer surface of the back plate, and a second gear is rotatably connected to the inner surface of the installation groove. The upper surface and the lower surface of the second gear are respectively engaged with a second rack, and the two longitudinal sides of the second racks facing each other are respectively provided with an extension plate and a limit plate.

[0010] Furthermore, a side plate is installed on the outer surface of the back plate, a second motor is installed on the outer surface of the side plate, and an output end of the second motor passes through the side plate and is installed with the second gear.

[0011] Furthermore, a protective shell is installed on the outer surface of the side plate, and the second motor is located inside the protective shell.

[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model starts the first motor through the controller, so that its output shaft drives the second rotating shaft to rotate through the coupling, and the second transmission wheel on the second rotating shaft then drives the first transmission wheel on the first rotating shaft to rotate synchronously through the belt, thereby rotating the first gear fixed to the first rotating shaft, and the rotation engagement of the first gear drives the first rack to slide upward along the slide groove in the shell. Since the handle of the electric umbrella is fixed in the clamping block at one end of the first rack, the upward movement of the first rack pushes the umbrella body smoothly out of the shell to the desired height. Then the user starts the electric umbrella itself through the controller, and the umbrella cover is It can be automatically opened to provide sunshade or rain protection. The coordinated use of the lifting components and the controller frees the user's hands, allowing them to always focus on controlling the wheelchair with both hands, greatly improving the operational safety and control stability of travel under complex weather conditions. At the same time, the automatic lifting and opening process started with one button of the controller significantly simplifies the operational steps of sunshade and rain protection, eliminating the tedious and physical exertion of manually taking out, opening and holding the umbrella, and providing a more convenient, labor-saving and efficient means of protection especially for elderly users with limited mobility, thereby significantly enhancing the user experience.

[0014] (2) The utility model forms a physical barrier on both sides of the user's back by arranging an extension plate and a limit plate on the back panel that can move toward the outside of the back panel at the same time. After the barrier is deployed, the electric push rod is immediately activated, so that its output end pushes the abutment plate downward until the abutment plate firmly contacts and presses the ground, thereby effectively increasing the overall grip of the wheelchair and preventing the wheelchair from sliding or overturning due to strong winds. The windshield formed by the extension plate is deployed and the abutment plate is connected to the ground to provide anti-overturning support, which together constitutes a protective mechanism that stabilizes the wheelchair and protects the user's safety in a strong wind environment.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The inner surface of the housing 901 is rotatably connected to a first rotating shaft 902. The outer surface of the first rotating shaft 902 is mounted with a first gear 903 and a first transmission wheel 904. The inner surface of the housing 901 is provided with a slide groove, and a first rack 905 is slidably connected to the interior of the slide groove. A clamping block 906 is mounted on one end of the first rack 905. The first rack 905 is meshed with the first gear 903. The electric umbrella 12 is clamped inside the clamping block 906.

[0028] The coordinated use of the lifting assembly 9 and the controller 10 frees the user's hands, allowing them to always focus on controlling the wheelchair with both hands, greatly improving operational safety and control stability in complex weather conditions. At the same time, the automatic lifting and opening process activated by the controller 10 with one button significantly simplifies the operation steps of sun protection and rain protection, eliminating the tedious and physically demanding process of manually taking out, opening, and holding the umbrella. This provides a more convenient, labor-saving, and efficient means of protection, especially for elderly users with limited mobility, thereby significantly enhancing the user experience.

[0029] The inner surface of the housing 901 is also rotatably connected to a second rotating shaft 907. The outer surface of the second rotating shaft 907 is mounted with a second transmission wheel 908. The second transmission wheel 908 is in transmission connection with the first transmission wheel 904 via a belt 909. A first motor 9010 is mounted inside the base 1. The output shaft of the first motor 9010 is connected to the second rotating shaft 907 via a coupling. A cover plate 9011 is clamped onto the upper surface of the housing 901.

[0030] The output shaft of the first motor 9010 is also equipped with an electromagnetic brake;

[0031] An electric push rod 13 is installed inside the base 1. The output end of the electric push rod 13 passes through the base 1 and is installed with an abutment plate 14.

[0032] The outer surface of the back plate 6 is provided with a mounting groove, the inner surface of which is rotatably connected to a second gear 15. The upper and lower surfaces of the second gear 15 are respectively meshed and connected to a second rack 16. The longitudinal sides of the two second racks 16 facing each other are respectively provided with an extension plate 17 and a limit plate 18.

[0033] A side plate 19 is mounted on the outer surface of the back plate 6 , and a second motor 20 is mounted on the outer surface of the side plate 19 . The output end of the second motor 20 passes through the side plate 19 and is mounted on the second gear 15 .

[0034] A protective shell 21 is installed on the outer surface of the side plate 19 , and the second motor 20 is located inside the protective shell 21 .

[0035] The input ends of the driving structure 2 , the electric umbrella 12 , the first motor 9010 , the second motor 20 and the electric push rod 13 are all electrically connected to the output end of the controller 10 .

[0036] When in use, the user sits on the base plate 5 with both hands on the armrests 8, and one of the hands operates the controller 10, and starts the driving structure 2 through the controller 10, so that the driving structure 2 drives the wheels 3 to rotate, and then drives the wheelchair to move. When sunshade or rain shelter is needed, the cover 9011 is removed from the shell 901, and then the first motor 9010 is started through the controller 10, so that its output shaft drives the second rotating shaft 907 to rotate through the coupling, and the second transmission wheel 908 on the second rotating shaft 907 then drives the first transmission wheel 904 on the first rotating shaft 902 to rotate synchronously through the belt 909, so that the first gear 903 fixed to the first rotating shaft 902 rotates, and the rotation of the first gear 903 drives the first rack 905 to slide upward along the slide groove in the shell 901. The handle of the umbrella 12 is fixed in the clamping block 906 at one end of the first rack 905. The upward movement of the first rack 905 smoothly pushes the umbrella body out of the shell 901 to the desired height. Then, the user starts the electric umbrella 12 itself through the controller 10, and the umbrella can be automatically opened to achieve the function of sunshade or rainproof. When the electric umbrella 12 needs to be retracted, the umbrella can be controlled to retract through the controller 10, and then the first motor 9010 is started by the controller 10, so that the output end of the first motor 9010 rotates in the opposite direction, so that the first rack 905 slides downward along the slide groove in the shell 901, and then the electric umbrella 12 is retracted into the shell 901. Then, the cover plate 9011 is snapped onto the upper surface of the shell 901 to complete the storage operation of the electric umbrella 12.

[0037] When encountering strong winds, the second motor 20 is started by the controller 10, so that its output shaft drives the second gear 15 to rotate. Since the second gear 15 is engaged with the two second racks 16 at the same time, the rotation of the second gear 15 drives the two second racks 16 to extend horizontally outward along the axial direction of the mounting groove of the back panel 6. The extension plate 17 fixed at one end of the second rack 16 is then smoothly pushed out from the mounting groove of the back panel 6, forming a physical barrier on both sides behind the user. After the barrier is unfolded, the electric push rod 13 is immediately started, so that its output end pushes the abutment plate 14 downward until the abutment plate 14 firmly contacts and presses the ground, thereby effectively increasing the overall grip of the wheelchair and preventing the wheelchair from skidding or overturning due to strong winds. The windshield formed by the extension plate 17 is connected to the ground with the abutment plate 14 to provide anti-overturning support, which together constitute a protection mechanism for stabilizing the wheelchair and protecting the user's safety in a strong wind environment.
