[0051] Please refer to the attached document. Figures 1-6 This application provides a multi-functional integrated component 100, which is applied to a backrest chair and is used to heat and vibrate the user's waist.

[0052] Please refer to the attached document. Figures 1-6In this embodiment, the multifunctional integrated component 100 includes a lumbar support 10, a flexible pad 20, a heating element 30, and a vibration element 40. The lumbar support 10 is disposed around the user's waist and extends along the circumferential direction of the waist. The flexible pad 20 is connected to the lumbar support 10 and can flexibly conform to the user's waist. The surface of the flexible pad 20 is provided with a heating area 20a and a vibration area 20b. The vibration area 20b and the heating area 20a have an overlapping area 20c. The overlapping area 20c is located on one side of the middle position of the flexible pad 20, or the overlapping area 20c is close to the middle position of the flexible pad 20. The heating element 30 is connected to the flexible pad 20 and is positioned relative to the heating area 20a. The heating element 30 outputs heat to the heating area 20a when in operation; the vibrating element 40 is connected to the flexible pad 20 and arranged relative to the vibration area 20b; the vibrating element 40 outputs vibration energy to the vibration area 20b when in operation; the vibrating element 40 and the heating element 30 are distributed at different thickness positions of the flexible pad 20, and can be arranged in a staggered or stacked manner; at this time, heat and vibration energy are integrated in the overlapping area 20c, and the heat and vibration energy massage the same position of the user's waist in the overlapping area 20c, so that the flexible pad 20 integrates heating and vibration, realizes the integrated massage function of the multifunctional integrated component 100, and enriches the functionality of the multifunctional integrated component 100.

[0053] Please refer to the attached document. Figures 1-6 In this embodiment of the application, the lumbar support 10 is disposed on the periphery of the user's waist and extends along the periphery of the waist; so that the lumbar support 10 can support the user's waist.

[0054] The flexible pad 20 is connected to the lumbar support 10 and can flexibly conform to the user's waist to make the user more comfortable during use and reduce the user's lumbar fatigue. The surface of the flexible pad 20 is provided with a heating area 20a and a vibration area 20b. There is an overlapping area 20c between the vibration area 20b and the heating area 20a. The overlapping area 20c is located on one side of the center of the flexible pad 20, or the overlapping area 20c is close to the center of the flexible pad 20, so that the heat and vibration energy output by the heating area 20a and the vibration area 20b can diffuse from the center of the flexible pad 20 to the periphery of the flexible pad 20.

[0055] The heating element 30 is connected to the flexible pad 20 and arranged relative to the heating area 20a; the heating element 30 outputs heat to the heating area 20a in the working state to heat the user's waist.

[0056] Vibrating element 40 is connected to flexible pad 20 and arranged relative to vibration area 20b; vibrating element 40 outputs vibration energy to vibration area 20b in working state; vibrating element 40 and heating element 30 are distributed at different thickness positions of flexible pad 20, and can be staggered or stacked; at this time, heat and vibration energy are integrated in overlapping area 20c, and heat and vibration energy massage the same position of the user's waist in overlapping area 20c, so that flexible pad 20 integrates heating and vibration, realizes the integrated massage function of multifunctional integrated component 100, and enriches the functionality of multifunctional integrated component 100.

[0057] In this embodiment, the flexible pad 20 has a first inner cavity 20d; the first inner cavity 20d serves as the internal space of the flexible pad 20, and the vibrating element 40 is accommodated in the first inner cavity 20d so that the vibrating element 40 can make full use of the space of the first inner cavity 20d. The vibrating element 40 is positioned and connected to the first inner cavity 20d, ensuring the positional accuracy of the vibrating element 40 relative to the flexible pad 20. At this time, the vibrating element 40 is built into the flexible pad 20. During the vibration process, the vibrating element 40 transmits the vibration energy through the flexible pad 20 to the vibration area 20b so that the vibration area 20b integrates the vibration energy, thereby facilitating the absorption of vibration energy when the user's waist is in contact with the vibration area 20b, so as to realize the vibration massage of the user's waist.

[0058] Please refer to the attached document. Figures 1-4 In this embodiment, the vibrating element 40 is located behind the heating element 30; the flexible pad 20 is provided with a spacer layer 21, which is located between the vibrating element 40 and the heating element 30 and separates the vibrating element 40 and the heating element 30. At this time, the vibrating element 40 and the heating element 30 are located at different thickness positions in the flexible pad 20. The spacer layer 21 can prevent the vibrating element 40 and the heating element 30 from interfering with each other and ensure that the vibrating element 40 and the heating element 30 can work normally. The vibrating element 40 and the heating element 30 are arranged on both sides of the spacer layer 21, making the way in which the vibrating element 40 and the heating element 30 contact the user's waist more reasonable.

[0059] Please refer to the attached document. Figures 1-4In this embodiment, a heat insulation member 211 is connected to the sidewall of the spacer layer 21 relative to the vibrating member 40. The heat insulation member 211 is located between the heating member 30 and the vibrating member 40 to reduce the impact of the heat output by the heating member 30 on the vibrating member 40; this prevents the vibrating member 40 from being affected by heat, thus extending its service life. The heat insulation member 211 serves as the heat insulation surface layer of the spacer layer 21, or it is attached to the sidewall of the spacer layer 21 facing the heating member 30 and connected to the heating member 30. When the heat insulation member 211 serves as the heat insulation surface layer of the spacer layer 21, it facilitates direct connection between the heating member 30 and the heat insulation member 211, reducing the internal structure of the flexible pad 20. When the heat insulation member 211 is attached to the sidewall of the spacer layer 21 facing the heating member 30 and connected to the heating member 30, it facilitates indirect connection between the spacer layer 21 and the heating member 30, thereby enabling double-layer isolation between the heating member 30 and the vibrating member 40.

[0060] Please refer to the attached document. Figures 1-4 In this embodiment, the vibrating element 40 is a vibration motor. Multiple vibrating elements 40 are located at different positions on the flexible pad 20, arranged on both sides of the center of the flexible pad 20. This arrangement increases the vibration range of the vibration area 20b, allowing the vibration energy output by the multiple vibrating elements 40 to cover multiple different positions on the user's waist. Optionally, two vibrating elements 40 are used. Each vibrating element 40 is located near and covered by the rear sidewall of the flexible pad 20, protecting it from physical damage.

[0061] Please refer to the attached document. Figures 1-4 In this embodiment, the flexible pad 20 has a second inner cavity 20e; the second inner cavity 20e serves as the internal space of the flexible pad 20, and is located at different positions from the first inner cavity 20d, and is not connected to each other; this allows the second inner cavity 20e and the first inner cavity 20d to be arranged independently. The heating element 30 is housed in the second inner cavity 20e, so that the heating element 30 can fully utilize the space of the second inner cavity 20e. The heating surface of the heating element 30 faces the heating area 20a along the thickness direction of the flexible pad 20, and the heating element 30 is closer to the front surface of the flexible pad 20 than the vibrating element 40; at this time, the heating element 30 is built into the flexible pad 20, and the heating element 30 conducts heat through the flexible pad 20 to the heating area 20a during the heating process, so that the heating area 20a integrates heat, thereby facilitating the absorption of heat when the user's waist is in contact with the heating area 20a, so as to achieve heating of the user's waist.

[0062] Please refer to the attached document. Figures 1-4In this embodiment, the heating element 30 and the vibration element 40 are stacked along the thickness direction of the flexible pad 20, so that heating and vibration can work synergistically in the same thickness direction of the flexible pad 20. This integrates heat and vibration energy into the flexible pad 20, and the area of ​​the heating region 20a is larger than the area of ​​the vibration region 20b. This allows for a more uniform distribution of heat along the thickness direction of the flexible pad 20. Optionally, the heating element 30 can be a heating wire, a heating sheet, or a heating layer of a flexible circuit board.

[0063] Please refer to the attached document. Figures 1-6 In this embodiment, the axis of the second inner cavity 20e is arranged obliquely or parallel to the axis of the middle position of the flexible pad 20; the heating element 30 is located inside the second inner cavity 20e, which is elongated; this allows the heating element 30 to be arranged vertically or obliquely, thus facilitating its adaptation to different waist curves of the user. The heating element 30 is arranged along the extension direction of the second inner cavity 20e, and in the working state, it outputs heat to different height positions of the flexible pad 20, so that the heating element 30 can heat different height positions of the user's waist, ensuring the heating effect on the user's waist.

[0064] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the multifunctional integrated component 100 further includes a controller 50, a first conductive element 60, and a second conductive element 70; the controller 50 is connected to the lumbar support 10 and is located on the rear side of the lumbar support 10 so that the controller 50 can be fixed to the rear side of the lumbar support 10; the flexible pad 20 is located on the front side of the lumbar support 10 so that the controller 50 and the flexible pad 20 are located on different side walls of the lumbar support 10, thereby facilitating the separate arrangement of the controller 50 and the flexible pad 20.

[0065] The first conductive element 60 electrically connects the controller 50 and the vibrating element 40, and passes through the internal space of the flexible pad 20, so that the controller 50 can be electrically connected to the vibrating element 40 through the first conductive element 60, thereby facilitating the controller 50 to control the start or stop of the vibrating element 40. The second conductive element 70 electrically connects the controller 50 and the heating element 30, and passes through the internal space of the flexible pad 20, so that the controller 50 can be electrically connected to the heating element 30 through the second conductive element 70, thereby facilitating the controller 50 to control the start or stop of the heating element 30. The first conductive element 60 and the second conductive element 70 both converge at the connection point between the controller 50 and the lumbar support element 10, ensuring the wiring effect of the first conductive element 60 and the second conductive element 70. The first conductive element 60 and the second conductive element 70 are spaced apart from each other, effectively avoiding electrical interference between the first conductive element 60 and the second conductive element 70, so as to realize independent control of the first conductive element 60 and the second conductive element 70. Alternatively, the first conductive element 60 and the second conductive element 70 are integrated on the same flexible circuit board, reducing connection points and interfaces, reducing the complexity and cost of the multi-functional integrated component 100, and simplifying the design of the multi-functional integrated component 100.

[0066] In this embodiment, the hardness of the lumbar support 10 is greater than that of the flexible pad 20; the lumbar support 10 is a plastic part so that it can support the user's force and prevent the lumbar support 10 from deforming.
