Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to an extended mobility scooter for the elderly. Background Art
[0002] A wheelchair is a device designed to help people with mobility impairments or complete loss of mobility to move and live independently; an electric wheelchair is a portable, battery-powered personal assistive mobile device designed to help individuals with mobility impairments or complete loss of mobility to move and live independently.
[0003] The wheel extension length of a wheelchair refers to the distance the wheels can extend during use. This characteristic is crucial for providing stability and balance, especially when climbing hills. In existing technologies: large, heavy-duty wheelchairs, due to their excessive size, while offering improved hill-climbing ability, are unsuitable for confined indoor spaces; while lightweight wheelchairs, with their narrower wheelbase, have lower hill-climbing ability. Although anti-tipping wheels are added, insufficient extension length of these wheels can cause instability when climbing hills or traversing uneven surfaces, affecting the safety and comfort of the rider. When the anti-tipping wheels extend too far, the drive wheels can easily become unsupported on uneven surfaces, reducing the contact area with the drive wheels and decreasing traction, making it difficult for the vehicle to maintain a firm grip and hindering normal wheelchair movement. Furthermore, existing wheelchairs require riders to lean forward as much as possible when climbing hills; forgetting to lean forward can easily lead to tipping over. Utility Model Content
[0004] The purpose of this utility model is to provide an extended mobility scooter for the elderly, in order to solve the problems mentioned in the background art, such as the inability of large wheelchairs to adapt to small indoor spaces and the instability of light wheelchairs when climbing hills due to their small front and rear wheel tracks.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] Extended mobility scooters for the elderly, including
[0007] A slide rail bracket, wherein universal wheels and drive wheels are fixedly installed at the front and rear ends of the slide rail bracket, respectively;
[0008] A telescopic drive component, wherein both ends of the telescopic drive component are fixedly connected to both ends of the slide rail bracket;
[0009] The main seat body, the lower end of which is rotatably connected to the front end of the slide rail bracket;
[0010] The lifting drive component has two ends that are rotatably connected to the front end of the slide rail bracket and the lower rear end of the main seat body, respectively.
[0011] Preferably, the slide rail bracket has a dovetail groove structure design.
[0012] Preferably, the telescopic drive component is an extended electric push rod.
[0013] Preferably, the lifting drive component is the electric push rod for leveling the main seat.
[0014] Preferably, one end of the main seat leveling electric push rod is rotatably connected to the lower front end of the slide rail bracket via a fixed bracket.
[0015] Preferably, a battery is installed above the rear end of the slide rail bracket.
[0016] Preferably, it also includes a secondary seat that is inserted above the rear end of the slide rail bracket.
[0017] Preferably, a special auxiliary body is provided below the slide rail bracket, and three connecting supports are fixedly connected to the front, middle and rear ends of the slide rail bracket, and three special auxiliary electric push rods are movably connected to the front, middle and rear ends of the special auxiliary body, and the three special auxiliary electric push rods are movably connected to the three connecting supports respectively.
[0018] Compared with the prior art, this utility model has the following advantages:
[0019] This utility model connects to the slide rail bracket by extending an electric push rod, and controls the drive of the extended electric push rod through an external controller, making it easy to adjust the wheel track. It can be used in small indoor spaces and ensures safe driving outdoors, with a user-friendly structural design.
[0020] This invention achieves optimal safety by adjusting the balance of the main seat through an electric leveling rod, allowing the center of gravity to shift forward and backward when going uphill or downhill, while ensuring that the driver and passengers maintain the best seating posture at all times.
[0021] When used outdoors, this utility model can also be equipped with a special auxiliary device for combined use. Through the controller, it can achieve barrier-free passage of outdoor stair steps with a height of less than 20 cm and a slope of less than 35 degrees.
[0022] When the device is not in use, it can be disassembled and folded for storage, reducing its footprint and facilitating loading and transportation.
[0023] This invention allows for forward movement throughout the entire process, and when driving on stairs, it moves straight up and down, making it easier for drivers and passengers to control.
[0024] The manufacturing process of this utility model is simple and convenient, easy to produce, and easy to operate and promote, with a very wide range of applications. Attached Figure Description
