Description

Technical Field

[0001] This invention relates to the field of walking aid technology, and in particular to a foldable box-type multifunctional electric walking aid. Background Technology

[0002] For users with lower limb weakness, unsteady gait, or impaired balance (such as the elderly, post-operative recoveries, and patients with chronic diseases), walking aids distribute body weight by using arm strength, reducing the load on the affected leg and lowering the risk of falls. Therefore, the use of foldable box-type walking aids is particularly important for the daily travel of the elderly and people with mobility impairments.

[0003] Traditional walking aids are mostly fixed structures, mainly composed of metal frames and support wheels. Although they can provide basic walking assistance, when carrying items, they are often attached externally, which can easily damage the stability of the original device and pose certain safety hazards. This is especially true for users with unstable gait, making it even more difficult to ensure safety. This greatly limits the user experience and travel convenience. Therefore, a foldable box-type multi-functional electric walking aid is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a foldable, box-type multi-functional electric walking aid that is electrically driven, not only meeting basic walking needs but also providing a comfortable seat and storage space, greatly improving the user's quality of life.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a foldable box-type multi-functional electric walking aid, including a folding box, a chassis mechanism and a control module, and an electric drive device disposed at the bottom of the chassis mechanism. The chassis mechanism includes a housing and a bottom plate fixedly connected to the front of the housing. A stepped partition is snapped into the inner side wall of the housing, and the stepped partition is arranged horizontally. The control module, located on the lower surface of the base plate, includes a PLC controller, a relay module, and an automatic obstacle avoidance sensor that are electrically connected to each other. The automatic obstacle avoidance sensor is used to detect obstacles in front and transmit signals to the PLC controller. The collapsible case includes: The telescopic rod is fixedly connected to the top of the housing; A hinge is fixedly connected to the outer surface of the telescopic rod, and the rotation axis of the hinge is parallel to the axis of the telescopic rod. The side panels are hinged to both sides of the telescopic rod and can rotate in the vertical direction. The rotating plate is composed of two rotating plates hinged to each other on their sides, with the side plates rotatably connected to both ends of the rotating plate assembly.

[0006] By adopting the above technical solution, the folding case of the walker of the present invention adopts a foldable design. The folding case, through the ingenious hinge structure of the telescopic rod, side panels, and rotating plate, can be quickly folded into a compact form when not in use, significantly reducing the space occupied by the folding case. When used as a wheelchair, first bring the side panels close together, then rotate them to a horizontal position, and push the side panels to the top of the shell. After folding, the side panels serve as the seat of the wheelchair. The automatic obstacle avoidance sensor is used to detect obstacles in front and transmit signals to the PLC controller. The PLC controller controls the start and stop of the electric drive device through a relay module, improving safety during use. When using the stroller, first pull the folding case outward, rotate the side panels on both sides of the telescopic rod to a vertical position, and pull the side panels to both sides to unfold the side panels and rotating plate to form an independent storage area. The side panels, rotating plate, and bottom plate form two independent storage spaces to meet storage needs. The stepped partition not only conceals the electric drive device but also expands the storage space and improves practicality, making it suitable for elderly or mobile individuals. Compared to traditional fixed-structure walking aids, this invention offers significant advantages in space utilization for use in the home and when traveling by people with disabilities. The folding design of the case allows it to be folded away for storage when not in use, saving space. Combined with a wheelchair, the case can be used as a wheelchair when folded, enabling functional conversion for temporary rest or mobility. The electric drive provides smooth electric assistance, greatly reducing the user's physical burden. Automatic obstacle avoidance sensors detect obstacles ahead, improving safety during use. In summary, this device, with its electric drive, not only meets basic walking needs but also provides a comfortable seat and storage space, greatly improving the user's quality of life. Especially when traveling, the portability and multifunctionality of the walking aid provide greater convenience and enhance their independent living abilities, making travel more convenient and comfortable for the elderly and people with mobility impairments. Furthermore, the automatic obstacle avoidance sensors detect obstacles ahead, improving safety during use.

[0014] By adopting the above technical solution, the electric drive device includes a gearbox, a motor, and a drive wheel axle, providing smooth electric assistance and greatly reducing the physical burden on the user.

[0015] A further provision of the present invention is that the electric drive device further includes a battery fixedly connected inside the housing, and the battery is electrically connected to the motor.

[0016] By adopting the above technical solution, a storage battery is installed inside the casing, ensuring the continuous power supply of this device.

[0017] A further feature of the present invention is that a grip switch is rotatably connected to the rear side of the housing, and the grip switch is electrically connected to the motor.

[0018] By adopting the above technical solution, the grip switch can turn the motor on and off, and the design of the grip switch allows the user to easily control the start and stop of the walker.
