[0027] Please see Figures 1 to 2 This utility model provides an electric multi-functional seat frame for the elderly, including: a backrest assembly 1, a backrest drive assembly 2, and a base 3. The backrest drive assembly 2 includes a mounting base 21, a transmission rod 22, a drive component 23, and a backrest adjustment switch 24. The mounting base 21 is mounted on the top of the base 3. The transmission rod 22 is inserted into the mounting base 21 and connected to the backrest assembly 1. The drive component 23 is connected to the transmission rod 22. The backrest adjustment switch 24 is electrically connected to the drive component 23 via a cable. The drive component 23 can drive the transmission rod 22 to rotate, and the transmission rod 22 then drives the backrest assembly 1 to move, thereby adjusting the tilt of the backrest assembly 1.

[0028] Please refer to the following: Figures 3 to 5 It should be noted that in this embodiment, the driving component 23 is a seat adjustment motor. The seat adjustment motor is connected to the power supply, and the backrest adjustment switch 24 is connected to the control power supply. The backrest adjustment switch 24 is equipped with buttons (such as a forward tilt button and a backward tilt button). By pressing the button, an electrical signal is output to the seat adjustment motor, which can control the forward and reverse rotation of the seat adjustment motor, providing power to adjust the backrest assembly 1, thereby adjusting the tilt of the backrest assembly 1.

[0029] When elderly people need to adjust the tilt of the backrest assembly 1, they only need to press the button on the backrest adjustment switch 24 to adjust the tilt of the backrest assembly 1. There is no need for manual adjustment, which makes the operation very convenient and improves the user experience.

[0030] In one specific embodiment, the backrest assembly 1 includes an upper connecting plate 11, a middle connecting plate 12, a lower connecting plate 13, a first connecting pipe 14, and a second connecting pipe 15. The middle connecting plate 12 is hinged between the upper connecting plate 11 and the lower connecting plate 13. The bottom end of the lower connecting plate 13 is connected to the mounting base 21. The first connecting pipe 14 is connected to the middle section of the middle connecting plate 12, and the second connecting pipe 15 is connected to the middle section of the lower connecting plate 13. When the driving member 23 drives the transmission rod 22 to move, the transmission rod 22 drives the lower connecting plate 13 to tilt forward or backward, thereby adjusting the tilt of the backrest assembly 1.

[0031] In one specific embodiment, the backrest assembly 1 also includes an armrest 16, which is mounted on the central connecting plate 12 and can provide support for the elderly to get up, as well as prevent impact from external objects.

[0032] In one specific embodiment, the backrest assembly 1 further includes an electrically heated wire mesh 17, which is connected to the first connecting pipe 14 and the second connecting pipe 15 and is used to connect to a power source. The electrically heated wire mesh 17 can generate heat after being powered on.

[0033] It should be noted that the electric multi-functional seat frame for the elderly in this embodiment has a packaging layer, which is mainly composed of sponge, polyester fiber base fabric, and polyester nylon base fabric. The electric heating wire mesh 17 is embedded inside the packaging layer. The packaging layer has soft characteristics, which can improve the user's sitting comfort.

[0034] In one specific embodiment, the mounting base 21 includes a base 211, a fixed side plate 212, an adjuster 213, and a rotating plate 214. The base 211 is mounted on the top of the base 3, the fixed side plate 212 is mounted on the base 211, the adjuster 213 is rotatably mounted on the fixed side plate 212, and the rotating plate 214 is mounted on the side of the adjuster 213 away from the fixed side plate 212. The lower connecting plate 13 is connected to the rotating plate 214, and the transmission rod 22 passes through the bottom end of the lower connecting plate 13 and the rotating plate 214 and is inserted at the center of the adjuster 213. When the driving member 23 drives the transmission rod 22 to move, the transmission rod 22 drives the adjuster 213 to rotate on the fixed side plate 212, and then the adjuster 213 drives the lower connecting plate 13 to tilt forward or backward, thereby adjusting the tilt of the backrest assembly 1.

[0035] In one specific embodiment, the two sides of the middle connecting plate 12 are bent to form retaining portions 121, and the upper half of the lower connecting plate 13 is retained within the retaining portions 121. The mounting base 21 also includes a protective member 215, which is mounted on the lower connecting plate 13 and clamped by the retaining portions 121. In this way, the installation strength of the lower connecting plate 13 can be increased.

[0036] In one specific embodiment, the electric multi-functional seat frame for the elderly also includes a battery module 4, which is electrically connected to the drive unit 23, the backrest adjustment switch 24, and the electric heating mesh 17. It should be noted that the power supply voltage provided by the battery module 4 to the drive unit 23 and the backrest adjustment switch 24 can be 12V, and the control power supply voltage provided by the battery module 4 to the electric heating mesh 17 can also be 12V. 12V falls within the safe extra-low voltage range, posing an extremely low risk of electric shock to the human body and ensuring high safety.

[0037] In one specific embodiment, the electric multi-functional seat frame for the elderly also includes a ventilation module 5, which is installed in the middle area of ​​the base 3.

[0038] It should be noted that when the base 3 and the backrest assembly 1 are packaged in the packaging layer, the smoothness of ventilation between the ventilation module 5 and the outside is not affected. The outside air can enter the packaging layer of the base 3 through the ventilation module 5. When the packaging layer of the base 3 forms a cushion, multiple ventilation holes can be designed inside the packaging layer in the cushion area to facilitate heat dissipation of the packaging layer at the cushion.

[0039] In one specific embodiment, the electric multi-functional seat frame for the elderly also includes a headrest assembly 6, which includes a headrest 61 and a T-shaped mounting bracket 62. The headrest 61 is mounted on the mounting bracket 62, and the mounting bracket 62 is fixedly connected to the top of the upper connecting plate 11.

[0040] It should be noted that a massage module can also be designed into the frame of the electric multi-functional seat for the elderly to realize the massage function, which can massage the back when the person is tired to relieve fatigue.

[0041] When in use, the elderly can sit on the electric multi-functional chair. When the elderly need to adjust the tilt of the backrest assembly 1, they only need to press the button on the backrest adjustment switch 24 to adjust the tilt of the backrest assembly 1. There is no need for manual adjustment. The operation is very convenient, easy and effortless, and has multiple functions, which improves user comfort and overall experience.

[0042] This invention is not limited to the description and embodiments described herein, and thus other advantages and modifications can be readily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and examples shown and described herein.
