Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model embodiment provides an electrically adjustable commode chair for elderly care, including a support 1. A groove plate 2 is installed on the side of the support 1, a guide plate 3 is slidably installed in the groove plate 2, a top plate 4 is installed above the guide plate 3, a slide rod 5 is installed on the side of the support 1, a slide plate 6 is slidably installed on the slide rod 5, a threaded rod 7 is rotatably installed on the side of the support 1, one end of the threaded rod 7 is equipped with an umbrella-shaped tooth A8, a transmission rod 20 is rotatably installed in the support 1, both ends of the transmission rod 20 pass through the support 1 and are equipped with umbrella-shaped teeth B10, a connecting plate 19 is installed on the slide plate 6, a connecting rod 9 is hinged above the connecting plate 19, a motor 11 is installed on the side of the support 1, armrests 12 are installed on both sides of the support 1, and a seat cushion 13 is hinged above the top plate 4.

[0028] In one embodiment, the inner side of the slide plate 6 is provided with a threaded groove, and the slide plate 6 and the threaded rod 7 are connected by threads. When the threaded rod 7 rotates, the slide plate 6 will slide along the slide rod 5 under the action of the threads.

[0029] In one embodiment, the umbrella-shaped tooth A8 meshes with the umbrella-shaped tooth B10, and the connecting rod 9 is hinged below the top plate 4. The umbrella-shaped tooth A8 at one end of the threaded rod 7 meshes with the umbrella-shaped teeth B10 at both ends of the transmission rod 20. When the threaded rod 7 rotates, it will drive the transmission rod 20 to rotate under the meshing action, ensuring the synchronicity of the movement of the two mechanisms and improving the stability of the overall operation.

[0030] In one embodiment, one end of the threaded rod 7 is installed at the output end of the motor 11, and the seat cushion 13 is made of polyurethane. Compared to materials such as hard plastic, polyurethane is not too cold at low temperatures, which can reduce the cold stimulation when elderly people come into contact with it and improve the comfort of use, making it especially suitable for autumn and winter.

[0031] In one embodiment, a sponge pad is provided above the armrest 12. The sponge pad is soft, has good heat insulation properties, is inexpensive and excellent, and is highly practical.

[0032] In one embodiment, a backrest 14 is hinged to the back of the support 1, a protruding plate 15 is mounted on the back of the support 1, an electric telescopic rod 16 is hinged to the protruding plate 15, a connecting seat 17 is mounted on the back of the backrest 14, and a hinge joint 18 is hinged inside the connecting seat 17. Under the mechanical coupling between the backrest 14 and the protruding plate 15 and the connecting seat 17, the backrest 14 can be angled around the hinge point with the support 1 to adapt to the different usage needs of the elderly.

[0033] In one embodiment, the hinge joint 18 is installed at the output end of the electric telescopic pole 16. During the extension and retraction of the electric telescopic pole 16, the hinge joint 18 undergoes an angular change within the connecting seat 17.

[0034] In operation, the following steps are taken: After the motor 11 starts, it drives the threaded rod 7 to rotate. Under the action of the thread, the slide plate 6 slides along the slide rod 5. When the slide plate 6 slides, it drives the connecting plate 19 to move synchronously. The connecting rod 9, which is hinged above the connecting plate 19, changes its angle and position accordingly. Under the mechanical coupling between the connecting plate 19 and the top plate 4, the connecting rod 9 drives the top plate 4 to move. At the same time, the guide plate 3 connected below the top plate 4 slides along the groove plate 2, guiding the movement of the top plate 4. During this process, the seat cushion 13, which is hinged above the top plate 4, moves together with the top plate 4, thereby supporting the elderly person's buttocks to complete the lifting action and effectively assisting the elderly person to get up. In addition, the umbrella-shaped tooth A8 at one end of the threaded rod 7 meshes with the umbrella-shaped teeth B10 at both ends of the transmission rod 20. When the threaded rod 7 rotates, it drives the transmission rod 20 to rotate under the meshing action, ensuring the synchronicity of the movement of the two mechanisms and improving the overall stability of operation.

[0035] When the backrest 14 needs adjustment, the electric telescopic rod 16 starts working, and its output end extends and retracts. Since the output end of the electric telescopic rod 16 is fitted with a hinge joint 18, which is hinged within the connecting seat 17 on the back of the backrest 14, and the side of the electric telescopic rod 16 furthest from the output end is hinged to the protruding plate 15 on the back of the support 1, the hinge joint 18 changes angle within the connecting seat 17 during the extension and retraction of the electric telescopic rod 16, and the angle of the electric telescopic rod 16 changes accordingly. Under the mechanical coupling between the backrest 14 and the protruding plate 15 and the connecting seat 17, the backrest 14 adjusts its angle around the hinge point with the support 1 to accommodate different usage needs of the elderly and improve user comfort.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
