Description

Technical Field

[0001] This utility model relates to the field of mobility scooters for the elderly, specifically a mobility scooter with rear wheel steering. Background Technology

[0002] Most lightweight mobility scooters for the elderly currently on the market are constructed using a combination of aluminum alloy and steel. While this material combination improves the vehicle's stability and durability to some extent, it also results in a weight that generally exceeds 20 kilograms. For a significant number of elderly people, this weight remains excessive. Furthermore, it's worth noting that some mobility scooters have a significant design flaw: a relatively large turning radius. This design feature causes considerable inconvenience in practical use, especially when turning in confined indoor spaces. Due to the large turning radius, these scooters often require multiple adjustments to the direction when turning in narrow corridors, living rooms, or other indoor areas, and may even need to be reversed to complete the turn smoothly. This not only increases the complexity of operation but also creates additional difficulties and safety hazards for the driver. Utility Model Content

[0003] The purpose of this invention is to provide a mobility scooter for the elderly with rear-wheel steering, which solves the problems mentioned in the background art.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rear-wheel steering mobility scooter for the elderly, comprising a front assembly A, a chassis assembly B located on the right side of the front assembly A, a seat assembly C located on the upper surface of the chassis assembly B, a carbon fiber body inside the chassis assembly B, a steering knuckle hinged to the front of the carbon fiber body, a front steering rod located on the front of the carbon fiber body, a front steering tie rod connected between the front steering rod and the steering knuckle, a middle steering linkage rod located at the left end of the front steering tie rod, a rear steering tie rod hinged to the middle steering linkage rod, a rear pivot shaft located at the end of the rear steering tie rod away from the middle steering linkage rod, and a carbon fiber rear cover snapped onto the surface of the carbon fiber body.

[0006] Furthermore, the vehicle adopts a modular design using carbon fiber materials, dividing the elderly mobility scooter into three main modules: A, B, and C. The front assembly A and the seat assembly C can be disassembled separately using a snap-fit ​​design, which greatly reduces the weight of each module.

[0007] Furthermore, the chassis assembly B can be controlled to weigh 10-11 kg.

[0008] Furthermore, the chassis assembly C achieves rear-wheel steering through a mechanical linkage structure of the central steering linkage, rear steering tie rod, and rear pivot shaft, which greatly reduces the turning radius of the vehicle.

[0009] This utility model provides a mobility scooter for the elderly with rear-wheel steering. It has the following advantages:

[0010] This rear-wheel steering mobility scooter for the elderly combines advanced carbon fiber materials with precise rear-wheel steering technology. This innovative approach not only significantly reduces the overall weight of the scooter, making it lighter and easier to handle, but also effectively reduces the turning radius during actual driving, improving driving flexibility and safety. This dual-optimized design not only makes it easier for the elderly to use the scooter, but also allows them to easily turn in narrow or complex environments, greatly facilitating their daily travel.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1-2 As shown, this utility model embodiment provides a rear-wheel steering mobility scooter for the elderly, including a front assembly A, a chassis assembly B located on the right side of the front assembly A, and a seat assembly C located on the upper surface of the chassis assembly B. The entire vehicle adopts a modular design using carbon fiber materials, dividing the mobility scooter into three main modules: A, B, and C. The front assembly A and seat assembly C can be disassembled separately using a snap-fit ​​design, which greatly reduces the weight of each module. The chassis assembly B can be controlled to 10-11 kg. The chassis assembly C is connected via a central steering linkage 4 and a rear steering tie rod 5. The mechanical linkage structure with the rear axle 7 enables the rear wheels to follow the steering. The interior of the chassis assembly B includes a carbon fiber body 6. The front of the carbon fiber body 6 is hinged with a steering knuckle 2. The front of the carbon fiber body 6 is provided with a front steering rod 1. A front steering tie rod 3 is connected between the front steering rod 1 and the steering knuckle 2. A middle steering linkage rod 4 is provided at the left end of the front steering tie rod 3. A rear steering tie rod 5 is hinged to the middle steering linkage rod 4. A rear axle 7 is provided at the end of the rear steering tie rod 5 away from the middle steering linkage rod 4. A carbon fiber rear cover 8 is snapped onto the surface of the carbon fiber body 6.

[0019] Working principle: This product is made of air-blown mold and carbon fiber material, which can quickly mass-produce lightweight and durable body structure modules. When the handlebars are turned, the front steering rod 1 will swing left and right with the front steering tie rod 3, thus realizing the steering of the front wheels. At the same time, the front steering rod 1 drives the middle steering linkage rod 4 through the cooperation of the slot and flange bearing. The middle steering linkage rod 4 pulls the rear steering tie rod 5 to swing back and forth, so that the rear wheel, which is fixed to the carbon fiber rear cover 8, rotates around the rear axle 7 together, thus realizing the rear wheel steering of the carbon fiber mobility scooter.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
