Description

Technical Field

[0001] This utility model relates to the field of electric wheelchair technology, and in particular to an electric wheelchair with adjustable angle. Background Technology

[0002] Electric wheelchairs are modern assistive devices upgraded from traditional manual wheelchairs by incorporating high-performance power drive units, intelligent control devices, batteries, and other components. Electric wheelchairs typically consist of a motor, battery, control system, wheels, seat, armrests, and footrests. Currently, electric wheelchairs offer a wide range of adjustable functions; for example, some armrests are height-adjustable, seat angles can be adjusted as needed, and the front wheel angles of some electric wheelchairs are also adjustable, enhancing driving stability and comfort. These features collectively improve the convenience and comfort of using electric wheelchairs. An existing electric wheelchair with a rain-proof function (publication number: CN213759006U) uses polyester fabric to block rainwater, and the use of protrusions allows rainwater to drip off to the corners, preventing it from dripping onto the surface of the electric wheelchair. This provides convenient rain protection in rainy weather and does not affect the use of the electric wheelchair, thus avoiding affecting the mobility of disabled people. However, relying solely on polyester fabric to cover the corners of the support panels and protrusions to guide the water does not effectively protect the front of the wheelchair. In oblique rainfall or during wheelchair movement, rainwater can easily drift in from the front, directly wetting the user's legs or the electric wheelchair, thus seriously affecting the travel experience and safety. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-angle electric wheelchair.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle electric wheelchair includes a wheelchair body and a top guard plate. A footrest is fixedly mounted on the wheelchair body. A connecting vertical plate is fixedly mounted on the top guard plate near the footrest. A guide rod two is movably mounted on the connecting vertical plate. A transparent retractable curtain is provided on the guide rod two. A rubber magnetic strip two is embedded in the footrest. A rubber magnetic strip one is embedded in the guide rod two. A connecting horizontal plate is fixedly mounted on the top guard plate. A guide rod one is movably mounted on the connecting horizontal plate. A side waterproof cloth is provided on one side of the guide rod one. A magnetic buckle is fixedly mounted on the inner side of the connecting horizontal plate. A fixing sleeve is fixedly mounted on the upper end of the guide rod one, and a magnetic block two is mounted on the fixing sleeve.

[0005] As a further embodiment of this utility model, a pull rod is movably installed inside the fixed sleeve, and a second magnetic block is fixedly provided at the top of the pull rod. The second magnetic block is magnetically connected to the magnetic buckle. The two ends of the transparent telescopic curtain are respectively connected to the top of the guide rod and the inner wall of the top guard plate by Velcro.

[0006] As a further embodiment of this utility model, the two ends of the side water-blocking cloth are respectively connected to the side wall of the guide rod and the inner wall of the top baffle plate by Velcro, a spring is sleeved on the pull rod, and the second rubber magnetic strip is magnetically connected to the first rubber magnetic strip.

[0007] As a further embodiment of this utility model, the two ends of the spring are respectively fixedly connected to the inner wall of the magnetic block and the fixed sleeve, and the pull rod is connected through the bottom of the fixed sleeve.

[0008] As a further embodiment of this utility model, the magnetic buckles are symmetrically distributed on the connecting horizontal plate, and a magnetic block is embedded in the upper side wall of the connecting vertical plate near the top guard plate.

[0009] As a further embodiment of this utility model, the connecting vertical plates are symmetrically distributed on the top guard plate, and the top guard plate is fixedly installed on the main body of the electric wheelchair.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When the electric wheelchair is in use, it is equipped with a connecting horizontal plate, side water-blocking cloth, guide rod one, pull rod, spring, magnetic buckle, and magnetic block two. Side water-blocking cloths are installed on both sides of the electric wheelchair body. Pulling the side water-blocking cloth unfolds it and it is positioned by magnetic attraction using magnetic block two and magnetic buckle. After use, pulling the pull rod again retracts the cloth and it is fixed by another set of magnetic buckles. Through the spring rebound and the combination of the two sets of magnetic buckles, it not only ensures the stability of the side water-blocking cloth in the unfolded state against wind and rain, but also accurately fixes it when retracted, preventing the cloth from loosening and shifting. By setting up a transparent telescopic curtain, guide rod two, connecting vertical plate, rubber magnetic strip one, and rubber magnetic strip two, the transparent telescopic curtain is unfolded and retracted by pulling guide rod two. The magnetic force is used to fix the water-blocking cloth in the unfolded and retracted states, which enhances the protection effect in rainy weather without affecting the flexibility of daily passage. At the same time, the transparent telescopic curtain and the side water-blocking cloths on both sides can form multi-directional protection from the top, front, and sides, significantly improving the safety and comfort of the electric wheelchair in rainy weather.

A connecting vertical plate 102 is fixedly installed on the side of the top guard plate 2 near the foot pedal 103. A guide rod 202 is movably installed on the connecting vertical plate 102. A transparent telescopic curtain 201 is provided on the guide rod 202. A rubber magnetic strip 301 is embedded in the foot pedal 103. A rubber magnetic strip 106 is embedded in the guide rod 202. A connecting horizontal plate 101 is fixedly installed on the top guard plate 2. A guide rod 104 is movably installed on the connecting horizontal plate 101. A side waterproof cloth 105 is provided on one side of the guide rod 104. A magnetic buckle 3 is fixedly installed on the inner side of the connecting horizontal plate 101. A fixing sleeve 4 is fixedly installed at the upper end of the guide rod 104. A magnetic block 5 is installed on the fixing sleeve 4.

[0016] In use, after the user is seated, pulling the guide rod 202 unfolds the folded side waterproof curtain 105 along the connecting horizontal plate 101. Once unfolded, pulling the rod 302 downwards releases the spring 303, causing it to spring back and engage with the magnetic buckle 3 above, completing the unfolded positioning. After unfolding the side waterproof curtains 105 on both sides in sequence, as needed, pulling the guide rod 202 slides downwards along the inner wall of the two sets of connecting vertical plates 102, causing the connected transparent telescopic curtain 201 to unfold. When the guide rod 202 slides to a position close to the foot pedal 103, the rubber magnetic strip 106 inside the guide rod 202 and the rubber magnetic strip 301 inside the foot pedal 103 attract each other, causing the guide rod 202 to adhere to the edge of the foot pedal 103, thus completing the fixation of the transparent telescopic curtain 201 after it is unfolded, forming a complete front protective surface. The transparent telescopic curtain 201, together with the side water-blocking cloths 105 on both sides, can form multi-directional protection from the top, front, and sides, enhancing the protective effect when traveling in rainy weather.

[0017] In this embodiment, a pull rod 302 is movably installed inside the fixed sleeve 4. A magnetic block 5 is fixedly provided at the top of the pull rod 302. The magnetic block 5 is magnetically connected to the magnetic buckle 3. The two ends of the transparent telescopic curtain 201 are respectively connected to the top of the guide rod 202 and the inner wall of the top guard plate 2 by Velcro.

[0018] When in use, the transparent telescopic curtain 201 is made of polyvinyl chloride, and the side water-blocking cloths 105 on both sides are made of polyester fiber composite material.

[0019] In this embodiment, the two ends of the side water-blocking cloth 105 are respectively connected to the side wall of the guide rod 104 and the inner wall of the top baffle plate 2 by Velcro. A spring 303 is sleeved on the pull rod 302, and the second rubber magnetic strip 301 and the first rubber magnetic strip 106 are magnetically connected.

[0020] When in use, the foot pedal 103 provides guidance and limit for the guide rod 104, ensuring that the side water-blocking cloth 105 does not shift or twist during the unfolding and retraction process, and maintaining the flatness of the cloth.

[0021] In this embodiment, the two ends of the spring 303 are fixedly connected to the inner wall of the magnetic block 5 and the fixed sleeve 4, respectively, and the pull rod 302 passes through and connects to the bottom of the fixed sleeve 4.

[0022] In use, the two sets of connecting vertical plates 102 provide guidance and limit for the guide rod 202, ensuring that the transparent telescopic curtain 201 moves in a fixed direction when it is extended or retracted, and maintaining the flatness and sealing of the protective surface.

[0023] In this embodiment, magnetic buckles 3 are symmetrically distributed on the connecting horizontal plate 101, and magnetic blocks 203 are embedded in the upper side wall of the connecting vertical plate 102 near the top guard plate 2.

[0024] When in use, the transparent telescopic curtain 201 and the side water-blocking cloths 105 on both sides are fixed with Velcro, so that individual parts can be disassembled and replaced, reducing the overall disposal and material waste.

[0025] In this embodiment, the connecting vertical plates 102 are symmetrically distributed on the top guard plate 2, and the top guard plate 2 is fixedly installed on the electric wheelchair body 1.

[0026] When in use, the rubber magnetic strip 106, magnetic block 203 and rubber magnetic strip 301 are all made of soft magnetic material, which can ensure that the transparent telescopic curtain 201 will not be washed away by rain when it is unfolded, and can be easily separated by hand when it is retracted.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the electric wheelchair body 1 is in use, after the user sits down, pulling the guide rod 104 causes the folded side waterproof cloth 105 to unfold along the connecting horizontal plate 101. After unfolding to the correct position, pulling the downward lever 302 releases the spring 303, which rebounds and pushes the spring 303 to engage with the upper magnetic buckle 3, completing the positioning of the unfolded state. After unfolding the side waterproof cloths 105 on both sides in sequence, according to the use needs, pulling the guide rod 202 slides down along the inner wall of the two sets of connecting vertical plates 102, causing the connected transparent telescopic curtain 201 to unfold. When the guide rod 202 slides to the position close to the foot pedal 103, the rubber magnetic strip 106 inside the guide rod 202 and the rubber magnetic strip 301 inside the foot pedal 103 attract each other, causing the guide rod 202 to unfold. The guide rod 202 adheres to the edge of the foot pedal 103, securing the unfolded transparent telescopic curtain 201 and forming a complete front protective surface. After use, pull the lever 302 again to separate the magnetic block 5 from the magnetic buckle 3, retracting the side water-blocking cloth 105 to its initial position. The magnetic block 5 is then embedded in another set of magnetic buckles 3 for fixation, positioning the retracted side water-blocking cloth 105. Next, overcoming the magnetic force, pull the guide rod 202 upwards, causing the transparent telescopic curtain 201 to retract synchronously. Move the guide rod 202 to the upper magnetic block 203 of the connecting vertical plate 102. Utilize the magnetic attraction between the rubber magnetic strip 106 and the magnetic block 203 to position the retracted transparent telescopic curtain 201, keeping it neatly folded and not affecting the normal use of the wheelchair, facilitating user operation, and improving protective performance.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
