Technical Field

[0001] This utility model relates to the field of electric wheelchair technology, and in particular to a multifunctional electric wheelchair device. Background Technology

[0002] Electric wheelchairs are upgraded versions of traditional manual wheelchairs by adding high-performance power drive devices, intelligent control devices, batteries, and other components. Equipped with a human-operated intelligent controller, these new-generation intelligent wheelchairs can perform multiple functions such as forward movement, backward movement, turning, standing, and lying down. They are high-tech products that combine modern precision mechanics, intelligent numerical control, and engineering mechanics.

[0003] A search revealed Chinese Patent Publication No. CN222032892U, which discloses an electric wheelchair designed to prevent tipping. The wheelchair includes a main body with an equipment box fixedly mounted in the middle. Inside the equipment box is a rear-tipping support assembly located at the rear of the wheelchair main body. Side-tipping support assemblies are located on both sides of the equipment box. A rotating shaft is rotatably mounted in the middle of the equipment box. The rear-tipping support assembly includes an electric push rod fixedly mounted to the top of the equipment box. A telescopic rod is fixedly mounted to the movable end of the electric push rod, and a support rod located outside the equipment box is fixedly mounted to the other end of the telescopic rod. A rear support wheel is rotatably connected to the bottom of the support rod.

[0004] The aforementioned device has the following drawbacks: although the wheelchair can prevent tipping, its functionality is relatively limited. In rainy weather, users need to wear additional rain gear to ride it, and in hot weather, users are easily exposed to high temperatures and sunburn. This causes various discomforts and inconveniences for users, making it unsuitable for use in many seasons. Therefore, a multi-functional electric wheelchair device is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a multifunctional electric wheelchair device, including an electric wheelchair body 1 and an operating armrest 2. The operating armrest 2 is fixedly connected to the front outer wall of the electric wheelchair body 1. A drive device 3 is fixedly connected to the bottom outer wall of the electric wheelchair body 1. An electric wheel body 4 is fixedly connected to the output end of the drive device 3. The electric wheel body 4 rotates under the drive of the drive device 3, thereby driving the entire electric wheelchair body 1 to move. An extension mechanism 5 and an auxiliary mechanism 6 are provided on the electric wheelchair body 1. The extension mechanism 5 includes a groove 51, which is formed on the top inner wall of the electric wheelchair body 1. The rear inner wall of the groove 51 rotates through a bearing. A rotating column 52 is connected, and a slot 54 engages with a hexagonal block 55 to fix the position of the rotating column 52 and prevent it from rotating accidentally during use. A slide 53 is provided on the inner side wall of the rotating column 52, and a slot 54 is provided on the outer right side wall of the electric wheelchair body 1. A hexagonal block 55 is slidably connected to the inner side wall of the slide 53. A bracket 56 is fixedly connected to the outer side wall of the rotating column 52, and a limit plate 57 is fixedly connected to the top outer wall of the bracket 56. A shield 58 is hinged to the inner walls of the left and right sides of the bracket 56. The shield 58 can be rotated around the hinge point. When unfolded, it can shield the user from sunlight and rain, and when folded, it is easy to store. A compression spring 512 is fixedly connected to the outer right side wall of the hexagonal block 55.

[0024] Reference Figures 2-4 The rotating column 52 penetrates the right outer wall of the electric wheelchair body 1. Wear-resistant pads are fixedly connected to the side outer walls of the hexagonal block 55 and the slot 54. The wear-resistant pads can reduce the frictional wear between the hexagonal block 55 and the slot 54 and extend their service life. The hexagonal block 55 is engaged with the right inner wall of the slot 54. The end of the compression spring 512 away from the hexagonal block 55 is fixedly connected to the right inner wall of the rotating column 52. The shield 58 contacts the rear outer wall of the limiting plate 57. A hydrophobic layer 59 is fixedly connected to the side outer wall of the shield 58. The hydrophobic layer 59 can enhance the waterproof performance of the shield 58, allowing rainwater to slide off quickly and improving the rain protection effect.

[0025] Reference Figures 3-4The auxiliary mechanism 6 includes a telescopic groove 61, which is located on the front outer wall of the electric wheelchair body 1. The telescopic groove 61 provides storage space for the T-shaped frame 612, allowing the auxiliary mechanism 6 to be retracted and hidden when not in use, thus avoiding taking up extra space. The T-shaped frame 612 is slidably connected to the inner walls on both sides of the telescopic groove 61. A sliding plate 62 is slidably connected to the inner wall on the front side of the T-shaped frame 612. A footrest 63 is fixedly connected to the bottom outer wall of the sliding plate 62, providing support for the user's feet and improving riding comfort. A movable plate 64 is slidably connected to the inner wall on the right side of the T-shaped frame 612, and the outer wall on the right side of the movable plate 64 is fixedly connected to... A pull handle 66 is fixedly connected to the right outer wall of the movable plate 64, which is connected to a telescopic spring 65. A plug plate 67 is fixedly connected to the left outer wall of the movable plate 64. Silicone pads are fixedly connected to the top and bottom outer walls of the pull handle 66. The silicone pads increase the friction between the pull handle 66 and the hand, improve the grip comfort, and also play a role in preventing slippage. A frosted pad is fixedly connected to the top outer wall of the foot pedal 63. The frosted pad increases the friction between the foot and the foot pedal 63, prevents the user's foot from slipping, and improves the safety of use. The plug plate 67 is snapped into the right inner wall of the sliding plate 62. The end of the telescopic spring 65 away from the movable plate 64 is fixedly connected to the right inner wall of the T-shaped frame 612.

[0026] Working principle: By pulling the hexagonal block 55 to separate it from the slot 54, the hexagonal block 55 is rotated to make the rotating column 52 rotate. The rotation of the rotating column 52 drives the bracket 56 to rotate. The bracket 56 rotates and is perpendicular to the top of the electric wheelchair body 1. Then, the cover plate 58 is flipped to cover the top of the electric wheelchair body 1, reducing the sun exposure and rainwater on the person in the electric wheelchair body 1, and reducing rainwater falling on the person during the rainy season. At the same time, when users of different heights sit down, the handle 66 is pulled to move the movable plate 64. The movement of the movable plate 64 drives the insertion plate 67 to move. The insertion plate 67 moves and separates from the sliding plate 62. Then, the height of the foot pedal 63 can be adjusted up and down to facilitate the person's foot movement and adjust the comfort. At the same time, when not in use, the T-shaped frame 612 is retracted into the telescopic groove 61 to prevent protrusions from affecting the surrounding people.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
