[0026] Please refer to the attached document. Figures 1-5 In this embodiment, the sponge 20 is connected to the plastic support 10 and is located on the side of the plastic support 10 facing the user's waist, so that the sponge 20 can be fixed on the side of the plastic support 10 facing the user's waist, thereby facilitating contact between the user's waist and the sponge 20.

[0027] The functional component 30 is connected to the sponge 20 and can act on the user's waist; the functional component 30 is at least two of the following: a vibrating component, an electric heating component, and a phototherapy component; each functional component 30 is distributed at different positions on the sponge 20 so that each functional component 30 can perform at least two of the following on the user's waist: vibration massage, heating massage, or phototherapy massage.

[0028] The button module 40 is located on the outer periphery of the sponge 20. The button module 40 includes a housing 41, a button 42, and a button control board 43. The housing 41 is located on the outer periphery of the sponge 20 and is connected to the elastic sleeve 60 via a leather piece 50. The leather piece 50 extends outward from the elastic sleeve 60 and is connected to the housing 41 so that the housing 41 can be fixed to the sponge 20. The button 42 is movably connected to the housing 41 so that the position of the button 42 relative to the housing 41 can be adjusted. The button 42 acts on the button control board 43.

This avoids the user needing to be behind the plastic support 10 to operate the button module 40, thus improving the ease of operation of the side button assembly 100.

[0029] Please refer to the attached document. Figures 1-3 In this embodiment, the housing 41 includes a first housing portion 411 and a second housing portion 412. The second housing portion 412 is disposed on the front side of the first housing portion 411, and the first housing portion 411 is connected to the second housing portion 412 so that the second housing portion 412 is fixed to the front side of the first housing portion 411. A through hole is formed between the first housing portion 411 and the second housing portion 412 for the leather part 50 to pass through. The leather part 50 is connected to the elastic sleeve 60 and passes through the through hole. The leather part 50 is connected to the first housing portion 411 or the second housing portion 412 so that the housing 41 can be connected to the leather part 50 through the first housing portion 411 or the second housing portion 412. The housing 41 adjusts its position relative to the sponge 20 as the leather part 50 bends, so that the housing 41 can be closer to or further away from the user's hand. This makes it easier for the user to press the button 42 by adjusting the housing 41, avoiding the need for the user to operate the button module 40 from the back of the plastic support 10, thus improving the ease of operation of the side button assembly 100.

[0030] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the first housing part 411 or the second housing part 412 is provided with a positioning post 4121. The positioning post 4121 passes through the leather part 50 and is positioned and connected to the leather part 50, so that the first housing part 411 or the second housing part 412 is in a stationary state relative to the leather part 50, thus ensuring the positional accuracy of the first housing part 411 or the second housing part 412 relative to the leather part 50.

[0031] The positioning post 4121 is connected to a connector 41211, which is located on the outside of the leather part 50 and restricts the leather part 50 from detaching from the positioning post 4121, so that the positioning post 4121 can be connected to the leather part 50 through the connector 41211, thus ensuring the connection stability of the positioning post 4121 relative to the leather part 50.

[0032] Please refer to the attached document. Figures 1-3 In this embodiment, the leather part 50 is provided with a positioning hole for the positioning post 4121 to pass through. The peripheral sidewall of the positioning post 4121 contacts the inner sidewall of the positioning hole so that the positioning post 4121 can be positioned and connected to the leather part 50 through the positioning hole.

[0033] The end of the positioning post 4121 is provided with a threaded hole 4121a. The connector 41211 is provided with a stud portion and a limiting portion. The stud portion is screwed into the threaded hole 4121a. The limiting portion is connected to the stud portion and serves as the end of the connector 41211 to limit the detachment of the leather part 50. This allows the stud portion to cooperate with the threaded hole 4121a to lock the connector 41211 and the positioning post 4121 together. At the same time, the limiting portion enhances the connection stability between the connector 41211 and the positioning post 4121.

[0034] Please refer to the attached document. Figures 1-3 In this embodiment, the end of the leather piece 50 furthest from the button module 40 is sewn to the elastic sleeve 60 and fixedly connected to the elastic sleeve 60, so that the leather piece 50 can be fixedly connected to the elastic sleeve 60 by sewing, thus ensuring the position of the leather piece 50 relative to the outer periphery of the sponge 20.

[0035] The first housing portion 411 is detachably connected to the second housing portion 412, or the first housing portion 411 is integrally connected to the second housing portion 412. When the first housing portion 411 is detachably connected to the second housing portion 412, the first housing portion 411 can be connected to or disconnected from the second housing portion 412, so that the first housing portion 411 can be opened or closed relative to the second housing portion 412. When the first housing portion 411 is integrally connected to the second housing portion 412, the connection strength between the first housing portion 411 and the second housing portion 412 is improved, ensuring the connection stability between the first housing portion 411 and the second housing portion 412.

[0036] The button control board 43 is installed in the first housing part 411 or the second housing part 412 so that the button control board 43 is fixed inside the first housing part 411 or the second housing part 412; the button 42 is arranged relative to the button control board 43 and is movably connected to the first housing part 411 or the second housing part 412 so that the button 42 touches the button control board 43 when pressed by the user, thereby facilitating the button 42 to control the functional component 30.

[0037] Please refer to the attached document. Figures 1-3 In this embodiment, when there are two functional components 30, the two functional components 30 are a vibrating component and an electric heating component, respectively. The vibrating component and the electric heating component are both installed on the same sponge 20 and stacked along the thickness direction of the sponge 20, so that the vibrating component and the electric heating component can heat and vibrate the same position of the user's waist. The vibrating component is connected to a first conductive component, and the electric heating component is connected to a second conductive component. The second conductive component passes through the plastic support body 10. The second conductive component and the first conductive component are both conductive wires. The second conductive component and the first conductive component both pass through the first wire hole of the plastic support body 10, so that the second conductive component and the first conductive component can extend to the button control board 43 through the plastic support body 10, thereby facilitating the button control board 43 to control the opening or closing of the vibrating component and the electric heating component.

[0038] Alternatively, the second conductive element and the first conductive element are integrated on the same flexible circuit board. The second conductive element and the first conductive element serve as conductive parts of the flexible circuit board and extend in different directions. The second conductive element extends toward the heating element, and the first conductive element extends toward the vibrating element, so that the vibrating element and the heating element can be electrically connected to the button control board 43 through the flexible circuit board, thereby facilitating the button control board 43 to output signals to the vibrating element and the heating element through the flexible circuit board.

[0039] In this embodiment of the application, when the heating element is a heating wire, the heating wire is laid along a serpentine path, a circular path, or a concentric circle path so that the heating wire can generate and transfer heat as evenly and efficiently as possible within a limited space; the heating wire is provided with a conductive end, which is electrically connected to a second conductive element so that the heating wire can be electrically connected to the second conductive element through the conductive end.

[0040] Alternatively, when the heating element is a heating layer, the heating layer is integrated into the flexible circuit board, and the heating layer and the second conductive element are integrated into the same flexible circuit board and electrically connected within the flexible circuit board. This eliminates the need for subsequent wire bonding and plugging processes, reduces contact resistance and the risk of poor soldering, and makes the whole board thinner, thus reducing the space occupied by the heating element.

[0041] Please refer to the attached document. Figures 4-5 In the second embodiment, the side button assembly 100 further includes an elastic sleeve 60, which is detachably fitted onto the plastic support 10 and the sponge 20. This allows the elastic sleeve 60 to connect to or detach from the plastic support 10 and the sponge 20, improving the ease of installation and removal and facilitating separate cleaning. The elastic sleeve 60 has a receiving cavity for accommodating the plastic support 10 and the sponge 20, allowing the elastic sleeve 60 to accommodate them through the space of the receiving cavity. A leather piece 50 is sewn onto the elastic sleeve 60.

[0042] The elastic sleeve 60 is sewn with a side button leather sleeve 61, which is located on the outer periphery of the elastic sleeve 60 and covers the housing 41 so that the elastic sleeve 60 can be connected to the housing 41 through the side button leather sleeve 61. The elastic sleeve 60 is provided with a clearance hole for exposing the button 42 so that the user can press the button 42 in the external environment of the elastic sleeve 60.

[0043] Please refer to the attached document. Figure 5 In the third embodiment of the application, a lumbar support chair 200 includes a side button assembly 100, which is part of the lumbar support chair 200. The lumbar support chair 200 can be placed on the seat, tabletop, desktop or sofa of an external chair. The lumbar support chair 200 has the function of supporting the waist and back, relieving fatigue from sitting for a long time, and improving the comfort of the user's sitting posture.

[0044] The lumbar support chair 200 also includes a metal support member 210. The plastic support body 10 is movably connected to the metal support member 210 and can swing in multiple directions relative to the metal support member 210 to adjust the position of the plastic support body 10 relative to the metal support member 210. This facilitates the plastic support body 10 to support the waist of different users and ensures the comfort of the user's waist.

[0045] An elastic module 220 is provided between the plastic support body 10 and the metal support member 210. The elastic module 220 is located between the plastic support body 10 and the metal support member 210 and applies an elastic force to the plastic support body 10, so that the plastic support body 10 can move elastically relative to the metal support member 210 through the elastic module 220. The sponge 20 connected to the plastic support body 10 is used to provide pressure for the user's waist. Under the pressure of the user's waist, it gathers and supports the user's waist, so that when the user's waist presses against the sponge 20, it is buffered by the elastic module 220, which avoids the user's waist approaching the sponge 20 too quickly and causing excessive impact on the plastic support body 10, thus preventing the user from falling backward.

[0046] refer to Figure 5 In the second embodiment, the metal support 210 is provided with a first support portion 2101; the elastic module 220 is connected to the first support portion 2101 and is arranged at an inclination relative to the central axis of the metal support 210; the elastic module 220 elastically acts on at least one position of the plastic support 10 so that the elastic module 220 can be connected to the plastic support 10 through the first support portion 2101, thereby facilitating the elastic movement of the plastic support 10 relative to the metal support 210 through the elastic module 220, so as to cushion the user's waist when it comes into contact with the plastic support 10.

[0047] The elastic module 220 also includes an elastic element 2201. One end of the elastic element 2201 is connected to the first support portion 2101 and is stationary relative to the first support portion 2101. The elastic element 2201 directly or indirectly supports the plastic support body 10 and applies an elastic force to the plastic support body 10, so that the sponge 20 connected to the plastic support body 10 provides elastic support to the user's waist. This allows the two ends of the elastic element 2201 to be connected to the first support portion 2101 and the plastic support body 10 respectively, thereby enabling the elastic movement of the plastic support body 10.
