Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, specifically an electric mobility scooter suitable for the elderly that can be used while standing or sitting. Background Technology

[0002] With the aging population, electric mobility scooters have become an important outdoor travel tool for many elderly people with limited mobility. Most existing electric mobility scooters only offer a seated driving mode. However, maintaining a seated position for extended periods can easily lead to discomfort in the hips and lower back, and for users with minor back problems or who need to stand for short periods, traditional mobility scooters cannot provide effective support, posing a safety hazard.

[0003] An existing patent (authorization announcement number: CN218085853U) discloses an electric mobility scooter for the elderly. The key technical point of the solution is to significantly reduce the vibration generated when the electric mobility scooter body travels on bumpy roads, so that the vibration ultimately transmitted to the user's hand is negligible. Therefore, it can reduce the user's discomfort. Even when traveling on continuously bumpy roads, the user can operate the electric mobility scooter body more effortlessly and conveniently, and the safety is also higher.

[0004] However, the above-mentioned technical solutions still have certain drawbacks. Seated mobility scooters provide users with a comfortable seat, which is suitable for long-term travel, but their structure is fixed and users are always in a seated position. Long-term riding may lead to poor blood circulation and cannot meet the user's need for intermittent standing activities. While standing mobility scooters allow users to maintain a standing posture, they are not suitable for elderly people with weak physical strength or poor balance to use for a long time. Therefore, a standing and sitting electric mobility scooter suitable for the elderly is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an electric mobility scooter suitable for the elderly, which can be used both standing and sitting, in order to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An electric mobility scooter suitable for the elderly that can be used for standing or sitting includes a frame, on which a walking mechanism that drives the scooter body to move, a seat mechanism, and a standing assistance mechanism are provided. The seat mechanism includes a seat cushion and a backrest, and the seat cushion is rotatably connected to the vehicle frame. The standing assistance mechanism includes an electric push rod and a transmission assembly. The electric push rod is fixed to the frame, and its output end is connected to the seat or backrest through the transmission assembly to drive the seat to move between a horizontal position and an upright position. It also includes a leg restraint installed on the lower front of the frame to limit the user's legs.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: As a further embodiment of this utility model: the transmission assembly includes a fixed plate fixed to the bottom of the seat cushion, and a sliding block driven by the electric push rod and slidingly engaged with the fixed plate.

[0008] As a further improvement of this utility model: the fixed plate is provided with a sliding groove, and the sliding block is provided with a slider that is adapted to the sliding groove, and the slider slides in cooperation with the sliding groove.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-5 As shown, an electric mobility scooter suitable for the elderly that can be used for standing or sitting includes a frame 1, on which a walking mechanism 2 for driving the scooter body is provided, a seat mechanism 5, and a standing assistance mechanism 6. The seat mechanism 5 includes a seat cushion 52 and a backrest 56, and the seat cushion 52 is rotatably connected to the frame 1. The standing assistance mechanism 6 includes an electric push rod 61 and a transmission assembly. In this embodiment, in the sitting mode, the transmission component supports and fixes the seat cushion 52 in a horizontal or slightly backward position to form a stable seat plane. The user can sit normally on the seat cushion 52 with their back against the backrest 56 for driving or resting. The sitting mode can be converted to the standing mode through the standing assistance mechanism 6, which makes it easier for the elderly to walk and stand during rehabilitation training and to recover atrophied muscle groups.

[0020] In one embodiment, such as Figure 2 As shown, the frame 1 also includes a drive assembly, including a motor and a rear wheel 4 driven by the motor. When the user issues a command through the controller, the battery supplies power to the motor, and the driven rear wheel 4, through friction with the ground, propels the entire frame 1 and the front wheel 26 forward, thereby enabling the mobility scooter to move.

[0021] In one embodiment, such as Figure 2 and Figure 3As shown, the walking mechanism 2 includes a steering assembly, including a steering rod 22 and a front wheel 26 connected to the steering rod 22. An adjustment disc 21 is provided on the side of the steering rod 22 and electrically connected to a motor. A connecting rod 23 is provided at the bottom of the steering rod 22, and a brake lever 24 is provided on the connecting rod 23. The user can rotate the steering rod 22 with both hands, and the bottom of the steering rod 22 directly drives the front wheel 26 to turn left or right through a mechanical connection, thereby changing the vehicle's direction of travel. The adjustment disc 21 on the side of the steering rod 22 is an electronic signal generator, electrically connected to the motor that controls the vehicle's speed. When the user rotates the adjustment disc 21, a continuous electrical signal is sent to the motor's controller. The controller precisely controls the power output to the drive motor based on the received signal strength, thereby adjusting the vehicle's speed. When the user pulls back or squeezes the brake lever 24, this force is transmitted and amplified through the connecting rod 23 mechanism at the bottom, ultimately pulling the brake cable connected to the wheel, causing the brake pads to clamp the brake disc, generating braking force, and achieving braking.

[0022] In one embodiment, such as Figure 5 As shown, the electric push rod 61 is fixed to the frame 1, and its output end is connected to the seat 52 or backrest 56 through the transmission assembly, used to drive the seat 52 to move between a horizontal position and an upright position; and a leg restraint 3 is installed on the lower front of the frame 1 to limit the user's legs; when the electric push rod 61 extends, the seat 52 is rotatably connected to the frame 1. The linear thrust from the push rod is converted into an upward and forward lifting torque through the transmission assembly, forcing the seat 52 to rotate forward and upward around its hinge point. The seat 52 smoothly rotates from a horizontal position to an inclined position, and finally reaches an upright position. When the user is in a standing position, during the transition from sitting to standing, the back of their lower legs will naturally and lightly rest on the leg restraint 3. The leg restraint 3 acts as a barrier to prevent the user's legs from unintentionally sliding backward or leaving the predetermined safe standing area.

[0023] In one embodiment, such as Figure 4 and Figure 5As shown, the transmission assembly includes a fixed plate 64 fixed to the bottom of the seat cushion 52, and a sliding block 62 driven by the electric push rod 61 and slidably engaged with the fixed plate 64. The fixed plate 64 is provided with a sliding groove, and the sliding block 62 is provided with a slider 63 adapted to the sliding groove, and the slider 63 slidably engages with the sliding groove. The backrest 56 is connected to the frame 1 through a sliding pair. The sliding pair includes a limiting cylinder 54 fixed to the frame 1 and a sliding rod 55 fixed to the backrest 56 and slidably engaged with the limiting cylinder 54. The seat mechanism 5 also includes an armrest 53, one end of which is hinged to the seat cushion 52 and the other end is hinged to the backrest 56. The electric push rod 61 outputs to push the sliding block 62, and the slider 63 on the sliding block 62 is embedded in the sliding groove of the fixed plate 64. When the sliding block 62 is pushed horizontally, the slider 63 slides in the groove. The slider 63 forces the fixed plate 64 to rotate around its hinge point with the frame 1. The sliding rod 55 on the backrest 56 slides in the tilt direction within the limiting cylinder 54 on the frame 1. This action allows the backrest 56 to follow the seat cushion 52 forward when the seat cushion 52 moves, and to maintain the angle of contact with the user's back by sliding upward, avoiding uncomfortable compression or separation. The armrest 53 maintains a relatively stable spatial position relative to the user. Whether in a sitting or standing position, the user's hands can be comfortably placed on the armrest 53 for continuous support.

[0024] The above embodiment discloses an electric mobility scooter suitable for the elderly, which can be used in both standing and sitting positions. The user issues a mode-changing command via a simple button or switch. The command is transmitted to the control system, which then activates the electric push rod 61. The linear movement of the electric push rod 61 pushes the sliding block 62 of the transmission component. The slider 63 on the sliding block 62 slides within a groove in the fixed plate 64 fixed to the bottom of the seat cushion 52. The horizontal thrust of the sliding block 62 is forcibly converted into rotational motion of the fixed plate 64 about its hinge point with the frame 1. The seat cushion 52 thus smoothly rotates from a horizontal seat position to an upright support plate position. As the seat cushion 52 rotates, the backrest 56, hinged to the seat cushion 52, slides upwards while moving forward with the seat cushion 52 under the constraint of the sliding pair (the sliding rod 55 is inside the limiting cylinder 54), thus providing continuous and stable support for the user's back. In standing mode, the user's legs are placed within the leg restraints 3. The leg restraint 3 acts as a physical barrier, effectively preventing the user's legs from slipping due to inertia when the vehicle accelerates or goes uphill, thus reducing the risk of falling backward.

[0025] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
