The utility model ensures the overall stability of the walker in the process of going up and down the stairs and other obstacles through the retractable structure of the front side support frame, and the planetary wheel with the motor and the booster can provide assistance to the user during the obstacle crossing process. At the same time, it takes into account the practical needs of users for walking training and auxiliary support and the psychological needs of wishing to complete outdoor activities alone and expand the scope of going out.

The material of the support frame 3 is made of light alloy to reduce the burden on the user. The overall arc-shaped structure conveys more security to the user. The height of the control handle 1 is set to 700-800mm, and the specific height can be adjusted according to the specific height of the user. Ensure that the height of the handle is flush with the user's buttocks during use, and the user's forearm and upper arm are preferably 15-20°.

The front support rod 4 can be retracted when going up the stairs and extended when going down the stairs as required. After the car body is in a horizontal position, the fixing bolt pops out to lock and fix the front support rod, ensuring that the car body can complete the climbing and descending stairs in a horizontal state. After entering the flat section, the fixed bolt retracts, the support rod returns to the initial position, and the assisting process continues.

The control handle 1 is provided with two front and rear control switches 2. The control handle includes two front and rear control switches, a level sensing device and a remote control device for controlling the front frame fixing bolt. The front control switch can activate the front side when it needs to complete the actions such as going up and down stairs. The active planetary wheel assists the user to perform movements such as going up and down the stairs through the rotation of the planetary wheel. After entering the flat road, the rotation of the planetary wheel can be controlled and closed. The rear control button controls the extension and contraction of the front support rod. When performing obstacle-surmounting activities such as going up and down stairs, if the level sensing device in the handle is in a non-level state, the user is prompted to adjust the switch to control the fixed bolt to be in a retracted state. The front side support bar is correspondingly extended or shortened due to gravity or pressure. When the vehicle body is in a horizontal state, the fixing bolt pops up to fix the front frame. In its original state, the body remains level. The device can ensure that during use, the main body of the walker where the handle is located is in a horizontal state, and will not be skewed or tipped due to uneven force.

The overall shape and size design of the control handle 2 conform to the structure of the human hand, and the surface is covered with anti-slip rubber material to ensure the comfort of use. At the same time, the adjustment buttons on both sides need to be pressed at the same time to realize related functions, which can effectively prevent potential safety hazards caused by accidental touch during use.

The front driving planetary gear 5 and the rear driven planetary gear 7 can play the role of assisting in completing obstacle-surmounting activities such as going up and down stairs. The front active planetary wheel 5 is driven to rotate by a small variable frequency speed regulation drive motor 6. When encountering an obstacle, the relay is turned on by the rear control switch of the control switch 2 to push out the electromagnetic push rod, until the electromagnetic push rod contacts the ground and continues to extend. It is long until the entire device can be lifted up with the help of the reaction force, and the planetary wheel can be turned counterclockwise to pass the obstacle. Since the user puts pressure on the walker after the front wheel has passed the first step, during the process of going over the obstacle The driving wheel only bears the weight of the walker, and there is no excessive requirement for the motor power. The driven wheel on the rear side will follow the driving wheel to climb over obstacles, and the outer sides of the front and rear planetary wheels are covered with anti-skid materials to ensure the safety of the use process.

The above is only the preferred implementation side of the present utility model, and is not intended to limit the present utility model in any form. Any technical personnel familiar with the present profession, without departing from the technical scope of the present utility model, will Any simple modifications, equivalent changes and modifications made in the examples still fall within the scope of the technical solutions of the present invention.
