All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Please refer to the attached document. Figures 1-12 This application provides a backrest chair 100, which is used to adjust the contact point between the human body and the seat to obtain a more comfortable angle and reduce user fatigue.

[0054] Please refer to the attached document. Figures 1-12 In this embodiment, the backrest chair 100 includes a support member 10, a hip support pad 20, a back support pad 30, and a controller 40. The support member 10 includes a first support portion 11 and a second support portion 12, which are integrated structures. Both the first support portion 11 and the second support portion 12 are arranged in an arc shape, with the second support portion 12 positioned above the first support portion 11. The hip support pad 20 is connected to the first support portion 11 and can flexibly conform to the user's hips. The back support pad 30 is connected to the second support portion 12 and can support the user's back. The back support pad 30 is connected to multiple functional components 31, which are at least one of a vibration motor, an electric heating element, and a red light element. The functional components 31 are located on the front sidewall of the second support portion 12 and connected to the same back support pad 30, so that the support member 10 can accommodate both hip and back support, thereby improving the functional effect of the backrest chair 100. The controller 40 is disposed on the rear side wall of the second support part 12; a conductive element 60 is provided between the controller 40 and the functional component 31. The conductive element 60 extends from the functional component 31 to the controller 40 and passes through the second support part 12 in the front-back direction. The controller 40 utilizes the rear space of the second support part 12, avoiding the controller 40 and the backrest cushion 30 from sharing the front space of the second support part 12, and avoiding affecting the backrest cushion 30 of the backrest chair 100.

[0055] Please refer to the attached document. Figures 1-12 In this embodiment of the application, the support member 10 includes a first support portion 11 and a second support portion 12, which are integral structures. Both the first support portion 11 and the second support portion 12 are arranged in an arc shape, and the second support portion 12 is disposed above the first support portion 11. This improves the structural strength of the support member 10 and ensures the structural stability of the support member 10.

[0056] The buttock pad 20 is disposed on the upper side of the first support part 11. The buttock pad 20 is connected to the first support part 11 and can flexibly fit the user's buttocks; so that the user's buttocks can make flexible contact with the first support part 11 through the buttock pad 20, thereby improving the user's buttocks comfort.

[0057] A back support cushion 30 is disposed on the front side of the second support portion 12. The back support cushion 30 is connected to the second support portion 12 and supports the user's back, allowing for flexible contact between the user's back and the back support cushion 30, thus improving the user's back comfort. The back support cushion 30 is connected to multiple functional components 31, each of which is at least one of a vibration motor, an electric heating element, and a red light element. These functional components 31 are disposed on the front sidewall of the second support portion 12 and connected to the same back support cushion 30, allowing them to massage the user's back during operation, further enhancing user comfort. Simultaneously, the support member 10 integrates hip and back support, improving the functional effect of the backrest chair 100.

[0058] The controller 40 is disposed on the rear side wall of the second support portion 12. A conductive element 60 is provided between the controller 40 and the functional component 31. The conductive element 60 extends from the functional component 31 to the controller 40 and passes through the second support portion 12 in the front-to-back direction, so that the controller 40 can be electrically connected to the functional component 31 through the conductive element 60, thereby facilitating the controller 40 to control the functional component 31 to start or stop. The controller 40 utilizes the rear space of the second support portion 12, avoiding the controller 40 and the backrest cushion 30 sharing the front space of the second support portion 12, and avoiding affecting the backrest protection range of the backrest cushion 30 of the backrest chair 100.

[0059] Please refer to the attached document. Figures 1-2 In embodiments of this application, the controller 40 includes a housing 41 and a circuit board 42. The housing 41 is connected to the second support 12 so that the controller 40 can be connected to the second support 12 through the housing 41. The housing 41 is provided with a receiving cavity 41a, which serves as the internal space of the housing 41. The circuit board 42 is installed in the housing 41 and is located in the receiving cavity 41a. This allows the circuit board 42 to make full use of the space of the receiving cavity 41a, thereby facilitating the restriction of the movement of the circuit board 42 by the inner sidewall of the receiving cavity 41a and preventing the circuit board 42 from shifting.

[0060] The second support part 12 is provided with a through hole 12a; the through hole 12a connects to the receiving cavity 41a, and the conductive component 60 passes through the through hole 12a and enters the receiving cavity 41a, so that the conductive component 60 can extend from each functional component 31 through the hole 12a and the receiving cavity 41a to the controller 40 for docking, so that the controller 40 is electrically connected to each functional component 31, so that the controller 40 can control each functional component 31.

[0061] Please refer to the attached document. Figures 1-2 In embodiments 8-10 of this application, the via 12a is arranged relative to the receiving cavity 41a and communicates along the thickness direction of the second support portion 12; this reduces the routing distance of the conductive element 60. The conductive element 60 is a conductive wire, a flexible circuit board, or a conductive sheet; one end of the conductive element 60 is electrically connected to the corresponding functional component 31; the other end of the conductive element 60 is connected to the circuit board 42; this allows the two ends of the conductive element 60 to respectively connect to the corresponding functional component 31 and the circuit board 42, thereby facilitating the circuit board 42 to output signals to the corresponding functional component 31. The backing pad 30 is provided with a wire passage 30a, through which the conductive element 60 passes and is subjected to the flexible force of the backing pad 30, so that the backing pad 30 protects the conductive element 60, preventing the conductive element 60 from being subjected to physical impact and extending the service life of the conductive element 60.

[0062] When the conductive element 60 is a conductive sheet, it serves as a signal transmission surface, but it typically has a large contact area. This is advantageous in scenarios requiring multi-point signal transmission or stable signal transmission. When the conductive element 60 is a flexible circuit board, it is a type of circuit board that can be bent and folded. In the flexible environment of the second support portion 12, it can adapt well to the shape changes of the second support portion 12. When the conductive element 60 is a conductive layer, it can be evenly distributed in the contact area between the second support portion 12 and the functional element 31.

[0063] Please refer to the attached document. Figures 1-2 In embodiments 8-10 of this application, the plurality of functional components 31 include a first functional component 311 and a second functional component 312. The first functional component 311 is a vibration motor, and the second functional component 312 is an electric heating element. The first functional component 311 and the second functional component 312 are stacked and arranged along the thickness direction of the back pad 30, so that the back pad 30 can integrate vibration and heating within a limited space. The back pad 30 is provided with a spacer layer, which is located between the first functional component 311 and the second functional component 312 to prevent the heat output by the second functional component 312 from being directly conducted to the vibration motor. The spacer layer can prevent the first functional component 311 and the second functional component 312 from interfering with each other, ensuring that the first functional component 311 and the second functional component 312 can each work normally. The first functional component 311 and the second functional component 312 are arranged on both sides of the spacer layer, making the contact between the first functional component 311 and the second functional component 312 and the user's back more reasonable.

[0064] A heat insulation element is connected to the sidewall of the spacer layer opposite to the first functional component 311. This heat insulation element is positioned between the second functional component 312 and the vibrating component to reduce the impact of heat output from the second functional component 312 on the vibrating component, thus preventing the vibrating component from being overheated and affecting its performance, and extending its service life. The heat insulation element serves as the heat insulation surface layer of the spacer layer, or it is attached to the sidewall of the spacer layer facing the second functional component 312 and connected to it. When the heat insulation element serves as the heat insulation surface layer of the spacer layer, it facilitates direct connection between the second functional component 312 and the heat insulation element, reducing the internal structure of the backing pad 30. When the heat insulation element is attached to the sidewall of the spacer layer facing the second functional component 312 and connected to it, it facilitates indirect connection between the spacer layer and the second functional component 312, thereby enabling double-layer isolation between the second functional component 312 and the vibrating component.

[0065] Please refer to the attached document. Figures 1-2 In embodiments 8-10 of this application, the back support pad 30 is adhesively attached to the second support portion 12. This allows the back support pad 30 to be fixed to the second support portion 12 via adhesive. Both the first functional component 311 and the second functional component 312 are housed within the back support pad 30. The first functional component 311 is positioned between the second functional component 312 and the second support portion 12. In its working state, the first functional component 311 transmits vibration energy to the front surface of the back support pad 30. In its working state, the second functional component 312 transmits heat to the front surface of the back support pad 30. At this time, the first functional component 311 and the second functional component 312 can work simultaneously at the same time, or they can work selectively at different times. When the first functional component 311 and the second functional component 312 can work simultaneously at the same time, the user's back can simultaneously experience both vibration and heating effects in the same area. When the first functional component 311 and the second functional component 312 can work selectively at different times, the user's back can experience either vibration or heating effects in the same area.

[0066] Please refer to the attached document. Figures 1-2 In embodiments 8-10 of this application, the conductive element 60 connected to the first functional element 311 serves as the first conductive element; the conductive element 60 connected to the second functional element 312 serves as the second conductive element; the first conductive element and the second conductive element can pass through the backing pad 30 side by side and converge at the same through hole 12a, so that the first conductive element and the second conductive element can extend to the controller 40 through the through hole 12a, thereby facilitating the electrical connection between the first conductive element, the second conductive element and the controller 40. At the same time, the inner contour of the through hole 12a restricts the range of motion of the first conductive element and the second conductive element.

[0067] Please refer to the attached document. Figures 1-2In embodiments 8-10 of this application, the plurality of functional components 31 further includes a third functional component 313, which is a red light component. The third functional component 313 emits red light outwards in its working state. The third functional component 313 is exposed on the front sidewall of the back support pad 30, while the first functional component 311 and the second functional component 312 are both built into the back support pad 30. This allows the third functional component 313 to be exposed to the external environment, thus facilitating the direct emission of red light to the user's back. The third functional component 313 is located close to the central axis of the back support pad 30, while the first functional component 311 and the second functional component 312 are positioned on one side of the central axis of the back support pad 30. This allows the third functional component 313 to be positioned at different locations relative to the first functional component 311 and the second functional component 312 within the back support pad 30, ensuring that the third functional component 313, the first functional component 311, and the second functional component 312 fully utilize the space of the back support pad 30.

[0068] The third functional component 313 includes a lamp board 3131 and multiple lamp beads 3132. The lamp board 3131 is electrically connected to the conductive component 60, and the multiple lamp beads 3132 are electrically connected to the same lamp board 3131, so that the lamp board 3131 can transmit signals to the multiple lamp beads 3132, thereby facilitating the start or stop of the multiple lamp beads 3132. The multiple lamp beads 3132 are used to output red light, so that the red light output by the multiple lamp beads 3132 can be conducted to the user's back to realize red light therapy on the user's back. Optionally, the lamp board 3131 is a flexible circuit board or a rigid circuit board.

[0069] The third functional component 313 also includes a light-transmitting cover 3133, which covers a plurality of LED beads 3132. The light-emitting ends of the plurality of LED beads 3132 face the light-transmitting cover 3133. The light emitted from the light-emitting ends of the plurality of LED beads 3132 is transmitted through the light-transmitting cover 3133, so that the light emitted from the light-emitting ends of the plurality of LED beads 3132 is conducted to the user's back through the light-transmitting cover 3133, thereby facilitating the convergence or dispersion of the light emitted from the light-emitting ends of the plurality of LED beads 3132 on the user's back.

[0070] Please refer to the attached document. Figures 1-2 7. In this embodiment of the application, the hip pad 20 is glued to the first support portion 11 and is located above the first support portion 11, so that the hip pad 20 can be fixed to the upper side of the first support portion 11 by adhesive. The hip pad 20 is provided with a plurality of grooves 20a, which are connected to form corresponding flow channels 20b. The flow channels 20b are used for gas to pass through, so that the gas can carry away the heat between the user's buttocks and the hip pad 20 during the flow of the gas in the flow channels 20b, thereby achieving a heat dissipation effect, ensuring the heat dissipation effect of the backrest chair 100, and improving the comfort effect of the hip pad 20 on the user's buttocks.

[0071] The upper surface of the buttock pad 20 converges along the middle of the buttock pad 20 and extends in an arc direction so that the outer surface contour of the buttock pad 20 can be adapted to the outer contour of the user's buttocks, so as to better fit the user's buttocks, ensure the fit between the user's buttocks and the buttock pad 20, and improve the comfort effect of the buttock pad 20 on the user's buttocks.

[0072] The groove 20a is formed by a downward indentation of the upper surface of the buttock cushion 20, and two adjacent grooves 20a are connected to each other to allow gas to flow along the multiple grooves 20a. The flow channel 20b has a main channel 20c and multiple branch channels 20d. The main channel 20c is opened along the front-to-back direction in the buttock cushion 20; the multiple branch channels 20d are arranged on both sides of the main channel 20c to allow gas to flow from front to back through the main channel 20c to the multiple branch channels 20d. The multiple branch channels 20d are arranged at an angle or perpendicular to the main channel 20c. The multiple branch channels 20d are connected to different positions of the main channel 20c to expand the position of the multiple branch channels 20d relative to the user's buttocks, thereby facilitating the removal of heat from the user's buttocks by the gas in the multiple branch channels 20d relative to the multiple branch channels 20d, and improving the comfort effect of the buttock cushion 20 on the user's buttocks.

[0073] When multiple branch channels 20d are arranged at an angle relative to the main channel 20c, the flow direction of the gas in the branch channels 20d is at a certain angle to the main channel 20c. This angle can generate a certain rotation or vortex in the gas during the branching process, which helps the gas mix and flow. When multiple branch channels 20d are arranged perpendicular to the main channel 20c, the perpendicular arrangement of the branch channels 20d can reduce the resistance when the gas enters the branch channels 20d, because the flow direction of the gas is consistent with the axial direction of the branch channels 20d.

[0074] The front end of the main channel 20c is provided with a first figure-eight opening 20e, which connects to the external environment. The width of the first figure-eight opening 20e gradually narrows along the front-back direction so that the gas in the external environment can gradually accelerate and concentrate when entering the main channel 20c. The narrowing figure-eight opening can reduce the turbulence generated when the gas enters the main channel 20c. Turbulence will lead to gas loss and flow instability.

[0075] Alternatively, the rear end of the main channel 20c is provided with a second figure-eight opening 20f, which faces the second support portion 12 and is able to connect to the external environment. The width of the second figure-eight opening 20f gradually expands along the front-to-back direction to facilitate the smooth discharge of gas from the main channel 20c to the external environment. When the gas is discharged from the main channel 20c, the gradually expanding second figure-eight opening 20f causes the gas to gradually slow down and disperse during discharge, reducing turbulence generated when the gas is discharged from the main channel 20c. Turbulence can lead to energy loss and flow instability.

[0076] Multiple drainage channels 20d are symmetrically arranged along the main drainage channel 20c, ensuring even heat dissipation on both sides of the user's buttocks. The symmetrical drainage channels 20d guide heat evenly from both sides of the user's buttocks to the main drainage channel 20c, preventing excessive heat dissipation on one side and insufficient heat dissipation on the other. The multiple drainage channels 20d converge towards the center of the main drainage channel 20c to concentrate the direction of heat flow, allowing heat to more efficiently gather from both sides of the user's buttocks to the main drainage channel 20c, and then dissipate through the main drainage channel 20c.
