Description

Technical Field

[0001] The utility model relates to the field of walking-assisting robots, in particular to a walking-assisting robot which can assist standing. Background Art

[0002] The walking-assisting robots in the prior art are used to assist users in strengthening leg-lifting or walking training, so as to help users solve the problem of insufficient lower limb stepping strength when walking due to decreased physical function. Conventional walking-assisting robots of this type include a wearable mechanism similar to an exoskeleton. When in use, the driving motor provided by the wearable mechanism drives the leg-lifting device and combines with the application of sensors to increase the leg-lifting strength so that the user can walk easily. However, since such walking-assisting robots do not have anti-fall measures, they are not used for lower limb walking rehabilitation training for the elderly with decreased physical function and people with lower limb dysfunction due to stroke, disability, etc., who have difficulty standing and walking due to the lack of anti-fall safety guarantees. Therefore, such walking-assisting machines are limited to people who can stand normally or have a certain walking ability. Therefore, the market application is not wide enough and cannot provide help to more people in need. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] As one aspect of the utility model, a walking robot capable of assisting standing is provided, which can be used for training the legs to lift and walk, and comprises: a base frame 1, two seat cushions 2 arranged side by side and independently, a backrest assembly 3, an electric push rod 4 for switching the backrest assembly 3 between a sitting height and a standing height, a servo electric cylinder 5 for driving the seat cushion 2 to alternately move, a connecting rod 6 and an armrest mechanism 7, wherein each seat cushion 2 is connected to a corresponding servo electric cylinder 5; the lower end of the electric push rod 4 and the lower end of the connecting rod 6 are both pivotally connected to the base frame 1, and the upper end of the electric push rod 4 and the upper end of the connecting rod 6 are both pivotally connected to the rear end of the armrest mechanism 7; the lower end of the backrest assembly 3 is connected to the rear end of the armrest mechanism 7, the first end of the servo electric cylinder 5 is pivotally connected to the seat cushion 2, and the second end of the servo electric cylinder 5 is movably connected to the armrest mechanism 7. Preferably, the base frame 1 is provided with a walking wheel 15 for walking. The battery 16 is used to supply power to the driving mechanism of the traveling wheel 15 to achieve traveling under electric drive.

[0022] Preferably, a waist strap 17 is provided on the backrest assembly 3 to fix the user's waist through the waist strap 17, which facilitates the transition between sitting and standing positions and also facilitates the user to maintain and stabilize the standing position.

[0023] Preferably, a knee strap 8 is provided at one end of the seat cushion 2 away from the backrest assembly 3. When assisting standing, the knee strap 8 is worn on the user's legs to connect the user's thigh part with the corresponding seat cushion 2, so that when the seat cushion 2 swings, the corresponding thigh part is driven to be lifted or lowered.

[0024] When it is needed, the utility model can be transported to the required place in the form of an electric wheelchair. When used as an electric wheelchair, the two cushions 2 are placed side by side in a horizontal state for the user to sit on and use the knee strap 8 to fix the thigh knees and the two cushions 2 respectively, and wear the weight-reducing suspension belt 14. When training is needed, the electric push rod 4 is extended to make the backrest assembly 3 and the armrest mechanism 7 rise from the height of the sitting position to the height of the standing position, and the weight-reducing suspension belt 14 is used to rise synchronously to assist the user to change from the sitting position to the standing position. In this process, the servo electric cylinder 5 contracts to rotate the corresponding cushion 2 to a vertical state to adapt to the standing position. Then, through the fixation of the knee strap 8 and the thigh, the two servo electric cylinders 5 drive the swing of the corresponding cushion 2 alternately in turn to realize the movement of the left and right thighs, so that in the auxiliary standing state, the movement of the walking wheel 15 and the servo electric cylinder 5 drive the cushion 2 to realize the rehabilitation training of lifting the legs to assist walking, and the weight-reducing suspension belt 14 prevents the messenger from falling.

[0025] Due to the adoption of the above technical solution, the utility model can be conveniently moved to a location or place that is convenient for the user to use, so as to carry out corresponding training.

[0026] Preferably, a swing arm 9 is provided on the side of the seat cushion 2, and a first connecting column 10 for rotationally connecting with the armrest mechanism 7 is provided at the upper end of the swing arm 9. Preferably, a second connecting column 11 for rotationally connecting with the servo electric cylinder 5 is provided at the upper end of the swing arm 9.

[0027] Preferably, an arc-shaped groove 12 is formed on the armrest mechanism 7 , and the second connecting column 11 is disposed in the arc-shaped groove 12 .

[0028] Preferably, a weight-reducing suspension belt 14 is provided on the top of the backrest assembly 3 through a suspension arm 13. When in use, the user wears the weight-reducing suspension belt 14, so that a part of the body weight can be carried by the weight-reducing suspension belt 14, so as to achieve the effect of adjusting the exercise load during exercise, and ensure the balance and anti-fall effect of the user during training, so as to adapt to users with different physical conditions to perform assisted standing and walking training in a safe state.

[0029] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
