[0024] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] When the present invention is implemented, the overall structure is designed as follows:

[0026] The main body of the crutch is composed of a bottom frame 1 and a top frame 10, which are connected by a support rod 2 to form a stable support structure. A universal wheel 3 with a brake and a passive wheel 4 with a drum brake are installed at the bottom of the bottom frame 1 to achieve flexible steering and stable driving.

[0027] A control rod 6 is installed above the bottom frame 1, one end of which is connected to the driving wheel 5, and the other end of which is installed with a speed regulating handlebar 7, a brake handle 8 and a handle 9, so as to facilitate user operation and control.

[0028] Walking aid and walking function:

[0029] The driving wheel 5 is driven by a motor, and the speed is controlled by the speed regulating handle 7 to realize the forward, backward and steering functions. The universal wheel with brake 3 and the passive wheel with drum brake 4 provide stable support and steering capabilities.

[0030] The brake handle 8 is used for emergency braking to ensure user safety.

[0031] Rest function:

[0032] A movable seat cushion 12 and a movable backrest 13 are installed on the top frame 10. The user can adjust the position and angle of the seat cushion and the backrest as needed to enjoy a comfortable rest experience.

[0033] A fixing clip 17 is provided at the bottom of the movable seat cushion 12 to ensure that the seat cushion is stable and does not shake.

[0034] Storage function:

[0035] A fence 14 is installed between the bottom frame 1 and the top frame 10 for storing personal items, such as mobile phones, wallets, water cups, etc., to increase the practicality of the device.

[0036] Intelligent control function:

[0037] The lithium battery 15 provides power for the motor, and the controller 16 is responsible for receiving operation instructions and controlling the operation of the motor. The controller 16 can be integrated with an intelligent chip to realize functions such as power display, speed regulation, and fault alarm.

[0038] Optionally, the crutch can also be equipped with a Bluetooth module or a wireless communication module to connect to a smartphone or other smart device to achieve advanced functions such as remote control and health monitoring.

[0039] Portability and foldable design:

[0040] The bottom frame 1 and the top frame 10 are both designed as foldable frames, which are convenient for reducing the volume when not in use, and are convenient for carrying and storage.

[0041] The speed regulating handlebar 7 and the brake handle 8 can be folded and stored along the end of the control rod 6 to further save space.

[0042] Working principle of the present invention:

[0043] When the user needs to walk, the speed and direction of the motor can be controlled by the speed regulating handlebar 7, thereby driving the driving wheel 5 to rotate and driving the entire crutch forward or backward. When turning, the universal wheel 3 with brake can be flexibly rotated to adapt to the change of direction. When the user needs to rest, the movable cushion 12 can be pulled out and the angle of the backrest 13 can be adjusted to sit down and rest. At the same time, the fence 14 can be used to store personal items such as mobile phones, wallets, etc.

[0044] When the power is insufficient, the user can charge the lithium battery 15 through the charger. The controller 16 also has an intelligent protection function, which will automatically cut off the power supply to protect the safety of the device when the battery power is too low or the motor is overheated.

[0045] In addition, the multifunctional electric crutch of the present invention can also be customized according to user needs, such as adding a Bluetooth module to achieve connection with a smartphone, installing health monitoring sensors and other advanced functions.

[0046] This multifunctional device can be used as a walking stick when the seat cushion and the cloth strip on the backrest of the rear fixing rod are installed. It can be used as a leisure chair by pressing down the fixing brake. The seat cushion, backrest and movable fixing rod can be folded down and the fixing pin can be inserted to use it as a forward-pushing walking stick. After folding the left and right sides, the front handlebars are folded down and to the left, and the T-shaped crutch handle can be used as a side-pushing crutch. It is equipped with two lithium batteries of less than 6Ah. After folding, the aluminum alloy material is used. It is small and light and can be taken on board an airplane, which is convenient for patients with foot problems to travel.

[0047] The handle of the T-shaped crutch is an adjustable handle, and the handrails on both sides can be adjusted in height, so the crutch is convenient to use.

[0048] This design material uses aluminum alloy, which is light.

[0049] The front driving steering wheel control lever is fixed by two supporting tubes. The upper end of the control lever is a T-shaped steering handle. The steering handle is equipped with a speed control handle and two brake handles. The two sides of the steering handle can be folded down. After the front supporting tube (including the steering tube) is fully folded and stored, it is turned to the left. The T-shaped crutch head handle is used for side pushing. When pushing forward to assist walking, the steering wheel should be fixed forward.

[0050] The steering tube is connected to the steering adjustment brake T-handle on the top and the steering drive wheel on the bottom. All five wheels are equipped with shock absorbers for comfortable driving.
