At the same time, it makes full use of the front and rear spaces of the plastic support body 11, thereby improving the space utilization rate.

[0052] Please refer to the attached document. Figures 1-8 In this embodiment, the plastic support 11 serves as a support component of the lumbar support module 10. The plastic support 11 is used to support the control plate 12, the flexible component 13, the first vibration component 14, and the first conductive component 15.

[0053] The control panel 12 is located on the rear side of the plastic support 11 and is connected to the plastic support 11 so that the control panel 12 can be fixed to the rear side of the plastic support 11.

[0054] The flexible component 13 is connected to the plastic support body 11 and is located on the side of the plastic support body 11 facing the user's waist, so that the plastic support body 11 can support the user's waist through the flexible component 13, thereby facilitating the user's waist to fit the flexible component 13; the flexible component 13 is provided with a first receiving groove 13a and a first wiring groove 13b; the first wiring groove 13b is connected to the first receiving groove 13a.

[0055] Please refer to the attached document. Figures 1-8 The first vibrating element 14 is accommodated in the first receiving groove 13a so that the first vibrating element 14 can make full use of the first receiving groove 13a, thereby facilitating the flexible member 13 to store the first vibrating element 14. The first vibrating element 14 can output vibration force in the working state so that the vibration force output by the first vibrating element 14 can be transmitted to the user's waist through the flexible member 13.

[0056] The first conductive element 15 is electrically connected to the first vibrating element 14. The first conductive element 15 is arranged along the first wiring groove 13b and passes through the plastic support body 11 to be electrically connected to the control board 12 so that the control board 12 can control the first vibrating element 14. This facilitates the integration of vibration massage effect into the plastic support body 11, avoiding the situation where it only provides support but cannot provide vibration massage. This improves the functionality of the functional lumbar support component. At the same time, it makes full use of the front and rear spaces of the plastic support body 11, improving space utilization.

[0057] In this embodiment, the control plate 12 is disposed on the side of the plastic support 11 facing away from the flexible member 13, so that the control plate 12 is on the other side of the plastic support 11 facing the user's waist, avoiding contact between the user's waist and the control plate 12; a first support portion 111 is provided on the side wall of the plastic support 11 facing away from the flexible member 13, and the control plate 12 is housed in the first support portion 111 and fixedly connected to the first support portion 111, so that the control plate 12 can be connected to the plastic support 11 through the first support portion 111; the first end of the first conductive member 15 is electrically connected to the first vibrating member 14, and the second end of the first conductive member 15 is electrically connected to the vibration function end of the control plate 12; so that the first vibrating member 14 can be connected to the vibration function end of the control plate 12 through the first conductive member 15, thereby facilitating the vibration function end to control the opening or closing of the first vibrating member 14.

[0058] Please refer to the attached document. Figures 1-8 The plastic support 11 is provided with a first wire hole 11a, which is connected to the first receiving groove 13a. The first conductive element 15 is arranged along the path of the first receiving groove 13a and the first wire hole 11a, so that the first conductive element 15 can extend from the inside of the first support 111 through the first wire hole 11a to the first receiving groove 13a, thereby facilitating the connection of the two ends of the first conductive element 15 to the control plate 12 and the first vibration element 14 respectively.

[0059] In this embodiment, a first boss portion 112 protrudes rearward from one side wall of the plastic support 11 facing away from the flexible member 13. The first boss portion 112 is provided with a second receiving groove 112a. The inner side wall of the second receiving groove 112a is covered by the flexible member 13. A portion of the flexible member 13 located in the second receiving groove 112a forms a corresponding first receiving groove 13a. This facilitates the support of the first vibrating member 14 through the first boss portion 112 and the portion of the flexible member 13, ensuring the supporting force of the flexible member 13 on the first vibrating member 14.

[0060] The first protrusion 112 and the first support 111 are located on the same side wall of the plastic support 11 and are arranged in the vertical direction so that the first protrusion 112 and the first support 111 can make full use of the rear space of the plastic support 11, thereby facilitating the separate arrangement of the first protrusion 112 and the first support 111 and ensuring the distance between the first vibrating member 14 of the first protrusion 112 and the control plate 12 of the first support 111.

[0061] Please refer to the attached document. Figures 1-8 In this embodiment, the lumbar support module 10 further includes a heating element 16 connected to the flexible element 13, so that the heating element 16 is fixed to the flexible element 13, thereby facilitating the conduction of heat output by the heating element 16 to the user's waist via the flexible element 13. The heating element 16 and the first vibration element 14 are arranged in a stacked or staggered manner along the thickness direction of the flexible element 13. When the heating element 16 and the first vibration element 14 are stacked along the thickness direction of the flexible element 13, they heat and vibrate the same position of the user's waist. When the heating element 16 and the first vibration element 14 are staggered along the thickness direction of the flexible element 13, they heat and vibrate different positions of the user's waist respectively.

[0062] The heating element 16 is connected to a second conductive element 161, which passes through a plastic support 11. Both the second conductive element 161 and the first conductive element 15 are conductive wires, and both the second conductive element 161 and the first conductive element 15 pass through a first wire hole 11a in the plastic support 11. This allows the second conductive element 161 to extend through the plastic support 11 to the control board 12, thereby facilitating the control board 12 to control the heating element 16 to turn on or off.

[0063] Alternatively, the second conductive element 161 and the first conductive element 15 are integrated on the same flexible circuit board. The second conductive element 161 and the first conductive element 15 serve as conductive parts of the flexible circuit board and extend in different directions. The second conductive element 161 extends toward the heating element 16, and the first conductive element 15 extends toward the first vibrating element 14, so that the heating element 16 and the first vibrating element 14 can be electrically connected to the control board 12 through the flexible circuit board, thereby facilitating the control board 12 to output signals to the heating element 16 and the first vibrating element 14 through the flexible circuit board.

[0064] Please refer to the attached document. Figures 1-8 In this embodiment, when the heating element 16 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 the second conductive element 161 so that the heating wire can be electrically connected to the second conductive element 161 through the conductive end.

[0065] Alternatively, when the heating element 16 is a heating layer, the heating layer is integrated into the flexible circuit board, and the heating layer and the second conductive element 161 are integrated into the same flexible circuit board and electrically connected within the flexible circuit board. This eliminates the need for subsequent wire bonding, plugging, and other 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 16.

[0066] In this embodiment, the functional lumbar support component further includes another lumbar support module 20, which is provided with a second vibrating element 21 and a third conductive element 22. The third conductive element 22 is electrically connected to the second vibrating element 21 and is electrically connected to the first conductive element 15, so that the second vibrating element 21 can conduct electricity with the first conductive element 15 through the third conductive element 22. The first conductive element 15 is connected to a docking terminal 151 and is electrically connected to the third conductive element 22 through the docking terminal 151, so that the first conductive element 15 and the third conductive element 22 can be energized, thereby facilitating the control board 12 to control the second vibrating element 21 through the first conductive element 15 and the third conductive element 22 to realize the start and stop of the second vibrating element 21.

[0067] In this embodiment, the functional lumbar support component also includes a power supply 30, which is disposed in either of the two lumbar support modules 10. When the power supply 30 is disposed in the other lumbar support module 20, the power supply 30 and the control board 12 are respectively located in the corresponding lumbar support module 10 and are electrically connected through corresponding conductive lines, so that the power supply 30 can increase the power to the control board 12, thereby facilitating the control board 12 to control the first vibrating element 14, the second vibrating element 21 and the heating element 16.

[0068] The flexible component 13 is made of sponge, and a button module 131 is connected to the flexible component 13. The button module 131 is located on the outer periphery of the flexible component 13 so that the user can press the button module 131 in the external environment. The button module 131 has a vibration control component and a heating control component. The button module 131 is connected to the sponge through leather so that the button module 131 is fixed to the sponge. The button module 131 is electrically connected to the control board 12 through a corresponding conductive wire so that the control board 12 can control the first vibrating component 14, the second vibrating component 21 and the heating component 16 through the operation of the button module 131. This allows the vibration control component and the heating control component to control the first vibrating component 14, the second vibrating component 21 and the heating component 16 respectively.

[0069] In the second application embodiment, a lumbar support chair 200 includes a functional lumbar support component.

[0071] An elastic module 220 is provided between the plastic support body 11 and the metal support member 210. The elastic module 220 is located between the plastic support body 11 and the metal support member 210 and applies an elastic force to the plastic support body 11, so that the plastic support body 11 can move elastically relative to the metal support member 210 through the elastic module 220. The flexible member 13 connected to the plastic support body 11 is used for the user's waist to press against it, and it gathers and supports the user's waist under the pressure of the user's waist. The flexible member 13 is a sponge, so that when the user's waist presses against the sponge, it is cushioned by the elastic module 220, which avoids the user's waist approaching the sponge too quickly and causing excessive impact on the plastic support body 11, and prevents the user from falling backward.

[0072] In the second embodiment, the metal support 210 is provided with a second support portion 2101; the elastic module 220 is connected to the second 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 body 11; so that the elastic module 220 can be connected to the plastic support body 11 through the second support portion 2101, thereby facilitating the elastic movement of the plastic support body 11 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 body 11.

[0073] The elastic module 220 also includes an elastic element 2201. One end of the elastic element 2201 is connected to the second support portion 2101 and is stationary relative to the second support portion 2101. The elastic element 2201 directly or indirectly supports the plastic support body 11 and applies an elastic force to the plastic support body 11, so that the flexible element 13 connected to the plastic support body 11 provides elastic support to the user's waist. This allows the two ends of the elastic element 2201 to be connected to the second support portion 2101 and the plastic support body 11 respectively, thereby enabling the elastic movement of the plastic support body 11.

[0074] The elastic element 2201 is a spring; one end of the spring near the second support portion 2101 is attached to the side wall of the second support portion 2101; the second support portion 2101 is provided with a first support arm 21011, which extends from the second support portion 2101 toward the spring and inserts into the gap of the elastic element 2201. Therefore, the first support arm 21011 is located on the outside of the end of the spring near the second support portion 2101 and restricts the movement of the end of the spring near the second support portion 2101, so that the elastic element 2201 is engaged with the second support portion 2101, so that the second support portion 2101 can be connected to the elastic element 2201 through the second support arm, thereby improving the connection strength between the elastic element 2201 and the second support portion 2101.
