Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, a sitting and walking assistive device includes a connecting rod 1 with an opening 11 located in the middle. The opening can be either a through hole or a blind hole. A connecting nut is installed inside the opening for securing the assistive device to a wheelchair. Connecting holes are also provided on both sides of the connecting rod for connecting the power cords of the left and right electric push rods. Support frames 2 are connected to both ends of the connecting rod 1. The support frames 2 have an inverted U-shaped structure and universal wheels at both ends. A base 3 is fixedly connected to each support frame 2, and an electric push rod is detachably connected to the base 3 via a screw. The electric push rod includes a body and a telescopic rod. The body is mounted on the base via a screw, and the telescopic rod is located within the body. The body is mounted at an angle on the base 3. A fixing sleeve 8 is provided at the upper end of the body 4. The telescopic rod 6 of the electric push rod extends upward through a through hole at one end of the fixing sleeve 8, and an armpit support 7 is connected to the top of the telescopic rod 6. The other end of the fixed sleeve 8 is provided with a hollow handle fixed sleeve 53, and a handle 5 is provided inside the handle fixed sleeve 53. The handle 5 includes a handle 55, and a control switch 54 electrically connected to the electric push rod 6 is provided inside the handle 55. Electric push rods are provided in the bases on both the left and right sides, and the electric push rods on the left and right sides are connected in parallel. The wires of the electric push rods on the left and right sides are routed in the connecting rod through the connecting holes at both ends of the connecting rod. An electrical box and a power supply are also installed on one side of the body. The electrical box can hold electrical components (such as power display, terminal blocks, etc.).

[0024] The electric actuators on the left and right support frames are connected in parallel. The electric actuators (containing DC motors), control switch 54, and power supply are connected. The control switch is a forward and reverse switch, and the three are connected according to the forward and reverse connection method of the motor. The forward and reverse rotation of the motor controls the raising or lowering of the telescopic rod, thereby controlling the up and down movement of the telescopic rod and assisting in changing the standing or sitting posture of the human body.

[0025] The electric actuator, power supply, and control switch are existing equipment on the market, and the length of the conductive wire is increased or decreased according to the needs of the patent in question.

[0026] like Figure 2 As shown, the body 4 is installed obliquely on the base 3 by a screw, so that the two armpit supports 7 are brought closer together. Since the telescopic rod of the electric actuator has a certain length, it has a certain elastic deformation range. When the telescopic rod of the electric actuator is extended, the armpit supports at the top of the telescopic rod will move closer to each other, and the angle of inclination and the elastic deformation of the telescopic rod itself can provide the user with a certain range of spacing adjustment. When the shoulder width is different, the user will automatically pull open or retract the spacing of the armpit supports when using it, so that people with different shoulder widths can use it with the armpit supports.

[0027] like Figure 4As shown, a fixing nut 61 is fixed above the telescopic rod 6 (e.g., by threaded or welded connection). The armpit support 7 is threadedly connected to the fixing nut 61 via a lifting screw 62. The upper end of the telescopic rod is hollow. The fixing nut is threaded onto the top of the telescopic rod via an external thread, and also has an internal thread. The lifting screw passes through the armpit support and connects to the internal thread of the fixing nut. Rotating the lifting screw controls the distance between the armpit support and the top of the telescopic rod, thus finely adjusting the distance between the armpit support and the ground while maintaining a constant telescopic rod height. This adjustment can be tailored to the user's needs, improving user comfort.

[0028] like Figure 1 and Figure 4 As shown, the handle 5 is inverted L-shaped, and its lower end is provided with multiple positioning holes 51. The handle fixing sleeve 53 is provided with an adapter hole. The handle 5 is fastened to the handle fixing sleeve 53 after passing through the adapter hole and the positioning hole via a positioning pin 52. By providing multiple positioning holes and changing the connection of the positioning pin 52 with different positioning holes, the vertical height of the handle can be adjusted. The handle 55 is located at the upper end of the handle 5.

[0029] Multiple positioning holes are provided at the lower end of the handle. By connecting positioning holes of different heights with the adapter holes, the height of the handle on the machine body can be controlled, thereby adjusting the distance between the handle and the armpit support to accommodate people with different arm lengths. The fixing sleeve can also be directly welded to the machine body, eliminating the need for a separate handle fixing sleeve.

[0030] This invention can be used alone or in conjunction with a wheelchair. When used alone, the telescopic rod of the electric push rod assists the user in standing, after which the user can walk freely with the assistance of this power-assist device. When it needs to be combined with a wheelchair, it is installed through the opening. After installation, the user can walk with the assistance of the wheelchair, and then use the power-assist device to assist in standing and walking.

[0031] This invention provides an assistive device to help non-paralyzed groups such as the elderly, patients, or rehabilitation personnel transition from a sitting to a standing position and walk while standing, thus partially replacing caregivers. This invention is not applicable to paralyzed individuals but is suitable for users who can stand independently on the ground; it only provides assistance and cannot replace the user's ability to stand.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
