Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and more specifically, to a sofa with massage function. Background Technology

[0002] In the field of massage equipment technology, such as functional sofas, the existing massage mechanism's walking guide rails mostly adopt a metal rack design. The metal rack has the characteristic of high rigidity and lacks the ability to adjust flexibly during the massage. When pressure is applied to the back of the human body, the metal rack cannot adapt to the curve of the back, which not only leads to insufficient fit between the massage mechanism and the human body, but also easily causes pain and discomfort due to rigid contact. Especially in home settings, it is difficult to meet the user's core needs for a comfortable experience. Utility Model Content

[0003] The purpose of this application is to provide a sofa with a massage function, which significantly improves the fit between the massage mechanism and the back curve through the adaptive deformation of the walking rack, effectively reducing the pain and discomfort caused by the rigid contact of existing metal racks, and improving the user experience.

[0004] The embodiments of this application are implemented as follows:

[0005] A first aspect of this application provides a sofa with a massage function, including a sofa body, a walking rack disposed within the sofa body, and a massage mechanism disposed on the walking rack. The massage mechanism is capable of reciprocating along the walking rack to massage a user sitting on the sofa body. The walking rack is capable of elastic deformation under external force to adjust the contact state between the massage mechanism and the user. This sofa with a massage function significantly improves the fit between the massage mechanism and the back curve through the adaptive deformation of the walking rack, effectively reducing the pain and discomfort caused by the rigid contact of existing metal racks, and improving the user experience.

[0006] As one possible implementation, along the moving direction of the traveling rack, limit switches are fixedly provided at both ends of the traveling rack, and limit members are fixedly provided at both ends of the massage mechanism. When the limit members contact the limit switches, the massage mechanism moves in the opposite direction.

[0007] In one possible implementation, an electronic control module is provided inside the sofa body, and a manual control module is provided on the sofa body. The manual control module, the electronic control module, and the massage mechanism are electrically connected in sequence. The manual control module is used to issue control commands, and the electronic control module is used to control the working state of the massage mechanism according to the control commands.

[0008] In one possible implementation, the sofa body includes a base, a seat, a backrest, a footrest, and a linkage mechanism. The base is connected to the seat, and the seat is connected to the backrest and the footrest via the linkage mechanism. A drive component is provided between the base and the linkage mechanism. The drive component is electrically connected to the electronic control module. The electronic control module is used to control the operation of the drive component, which drives the linkage mechanism to move, thereby adjusting the angle between the seat, the backrest, and the footrest.

[0009] In one possible implementation, the foot support is connected to the linkage mechanism via a pivot, and an elastic element is provided between the foot support and the linkage mechanism. The elastic element is used to drive the foot support to move toward the side away from the linkage mechanism.

[0010] As one possible implementation, the seat portion and / or the backrest are provided with a receiving space, and the traveling rack is installed in the receiving space.

[0011] In one possible implementation, the seat includes a seat frame and a seat upholstery fixedly disposed outside the seat frame, the backrest includes a backrest frame and a backrest upholstery fixedly disposed outside the backrest frame, and hooks are provided on opposite sides of the seat frame and / or the backrest frame, with an elastic support member provided between the two hooks.

[0012] As one possible implementation, the sofa body also includes two armrests disposed on the left and right sides of the seat portion. Each armrest includes an armrest frame and an armrest upholstery fixedly disposed outside the armrest frame. The armrest frame is fixedly connected to the seat frame, and at least one armrest is provided with a bracket for fixing electronic devices.

[0013] In one possible implementation, the seat frame, the backrest frame, and the armrest frame are all blow-molded parts, and the seat upholstery, the backrest upholstery, and the armrest upholstery all include a covering and a filler, with the filler filling the covering.

[0014] As one possible implementation, the traveling rack is made of titanium alloy, spring steel, silicone rubber, modified plastic, or nickel-titanium alloy.

[0015] The beneficial effects of the embodiments of this application include:

[0016] This massage-functional sofa includes a sofa body, a walking rack within the sofa body, and a massage mechanism mounted on the walking rack. The massage mechanism moves back and forth along the walking rack to massage the user sitting on the sofa. The walking rack can elastically deform under external force to adjust the contact state between the massage mechanism and the user. After the user activates the massage function, a micro motor drives a gear set to mesh with the walking rack, causing the massage mechanism to move up and down along the walking rack to cover areas such as the user's back and waist. The massage heads, through rotation or reciprocating motion, combined with the movement of the massage mechanism, perform kneading, tapping, and other massage actions, acting on the body's muscles and acupoints. When the user's back contacts the backrest of the sofa body, the curve of the back applies pressure to the walking rack in different directions. For example, the pressure is greater in the shoulder area and less in the waist area, causing differential deformation of the rack at different locations. Under pressure, the walking rack elastically bends, and its curvature gradually matches the curve of the user's back. For example, when in a normal upright sitting posture, the toothed rack has a slight arc shape; when the user leans back, the curvature of the toothed rack increases, always keeping the massage head of the massage mechanism in close contact with the user's back. In addition, the elastic traveling toothed rack can transform the rigid contact between the massage head and the body into elastic contact, which plays a buffering role, reduces the impact force at the moment of contact, and can also absorb the vibration of the massage mechanism during movement, reducing overall noise and improving the user experience.

[0030] Please refer to the reference. Figures 1 to 8 This application provides a sofa with a massage function, including a sofa body, a walking rack 34 disposed within the sofa body, and a massage mechanism 35 disposed on the walking rack 34. The massage mechanism 35 can reciprocate along the walking rack 34 to massage a user sitting on the sofa body. The walking rack 34 can elastically deform under external force to adjust the contact state between the massage mechanism 35 and the user. This sofa with a massage function significantly improves the fit between the massage mechanism 35 and the back curve through the adaptive deformation of the walking rack 34, effectively reducing the pain and discomfort caused by the rigid contact of existing metal racks, and improving the user experience. For example, the material of the walking rack 34 can be titanium alloy, spring steel, silicone rubber, modified plastic, or nickel-titanium alloy, etc.

[0031] It should be noted that the sofa includes a sofa body, a walking rack 34, and a massage mechanism 35. The sofa body serves as the basic frame of the entire sofa, with space reserved inside for the installation of the walking rack 34. The curvature of the sofa body should conform to ergonomic design to provide basic support for the user. The fabric of the sofa body can be made of breathable and skin-friendly materials, such as breathable linen covered with high-elasticity sponge, to ensure comfort during prolonged sitting. The walking rack 34 can be made of high-strength elastic material, capable of controlled elastic bending under external force, with a bending curvature range of 0° to 15°. To accommodate the back curves of different users, the surface of the traveling rack 34 is provided with standard teeth, providing a transmission track for the movement of the massage mechanism 35. At the same time, the elasticity of the traveling rack 34 allows it to be used as an elastic support 24. The massage mechanism 35 is mounted on the traveling rack 34 and has a built-in micro motor and gear set. Through the meshing of the gear set with the traveling rack 34, the massage mechanism 35 can move back and forth along the traveling rack 34. The massage mechanism 35 is equipped with massage heads, which can provide various massage techniques such as kneading and tapping.

[0032] After the user activates the massage function, the micro motor drives the gear set to mesh with the walking rack 34, causing the massage mechanism 35 to move up and down along the walking rack 34 to cover the user's back, waist, and other areas. The massage head, through rotation or reciprocating motion, combined with the movement of the massage mechanism 35, performs kneading, tapping, and other massage actions, acting on the body's muscles and acupoints. When the user's back contacts the backrest 30 of the sofa body, the curve of the back applies pressure to the walking rack 34 in different directions. For example, the pressure is greater in the shoulder area and less in the waist area, causing the rack to deform differently at different locations. Under pressure, the walking rack 34 elastically bends, its curvature gradually matching the curve of the user's back. For example, in a normal upright sitting posture, the rack is slightly curved; when the user leans back, the curvature of the rack increases, always maintaining the massage head of the massage mechanism 35 in contact with the user's back. In addition, the flexible walking toothed rack 34 can transform the rigid contact between the massage head and the human body into an elastic contact, which plays a buffering role, reduces the impact force at the moment of contact, and can also absorb the vibration when the massage mechanism 35 moves, reduce the overall noise, and improve the user experience.

[0033] As one possible implementation method, such as Figure 4 As shown, along the moving direction of the traveling rack 34, limit switches 341 are fixedly installed at both ends of the traveling rack 34, and limit members 351 are fixedly installed at both ends of the massage mechanism 35. When the limit member 351 contacts the limit switch 341, the massage mechanism 35 moves in the opposite direction.

[0034] It should be noted that, along the moving direction of the traveling rack 34 (usually vertical), a limit switch 341 is fixedly installed at each of the opposite ends (such as the top and bottom) of the traveling rack 34, and a limit member 351 (such as a protrusion) is fixed at each of the opposite ends (such as the top and bottom) of the massage mechanism 35. The axis of the limit switch 341 is perpendicular to the moving direction of the traveling rack 34, ensuring that the limit member 351 can be accurately triggered when it moves.

[0035] The massage mechanism 35 moves upward from the middle of the traveling rack 34. The top limiter 351 gradually approaches the top limit switch 341. When the top limiter 351 contacts the top limit switch 341, the internal contacts of the limit switch 341 close (or the photoelectric signal is blocked), generating an electrical signal. After receiving the electrical signal, the sofa's electronic control module 70 immediately cuts off the forward power supply to the micro motor and connects the reverse power supply, causing the massage mechanism 35 to begin moving downward. Similarly, when the bottom limiter 351 triggers the bottom limit switch 341, the massage mechanism 35 reverses direction again, achieving reciprocating motion. This design, through the combination of mechanical limiting and electrical control, achieves automatic reversing and travel protection of the massage mechanism 35, further improving the safety and reliability of the sofa.

[0036] As one possible implementation method, such as Figure 2 As shown, an electronic control module 70 is installed inside the sofa body, and a manual control module 71 is installed on the sofa body. The manual control module 71, the electronic control module 70 and the massage mechanism 35 are electrically connected in sequence. The manual control module 71 is used to issue control commands, and the electronic control module 70 is used to control the working state of the massage mechanism 35 according to the control commands.

[0037] It should be noted that the manual control module 71 serves as the user's command input, and the electronic control module 70 serves as the command execution center. Through electrical connection, they achieve precise control of the working state of the massage mechanism 35, bringing users a convenient and personalized massage experience. Specifically, the electronic control module 70 is located inside the sofa body (such as the backrest 30), and the manual control module 71 is located on the sofa body (such as the armrest 60). The manual control module 71 can be a button-type hand controller or a touch screen hand controller. The manual control module 71, the electronic control module 70, and the massage mechanism 35 can be electrically connected in sequence via cables. The user selects the massage mode (such as kneading, tapping), intensity (level 1-5), and time (15-60 minutes) through the buttons on the manual control module 71 or the touch screen, generating corresponding digital signals (such as binary instruction codes). The manual control module 71 transmits the instruction codes to the electronic control module 70 via cables. During transmission, the signal can be filtered and amplified to ensure that the instruction is not distorted. The main control chip of the electronic control module 70 parses the instruction codes, calls the corresponding massage program (such as kneading massage, intensity level 2, time 15 minutes), and controls the operation of the micro motor of the massage mechanism 35 through the drive circuit, while simultaneously controlling the action mode of the massage head.

[0038] This intelligent control system, which works in collaboration between the electronic control module 70 and the manual control module 71, upgrades traditional massage sofas into customizable and easy-to-operate health home devices through precise command transmission, rich function adjustments, and reliable safety protection. It not only meets the daily massage needs of families but also plays a valuable role in professional scenarios such as medical and commercial settings, helping to promote the development of massage furniture towards intelligence and personalization.

[0039] As one possible implementation method, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the sofa body includes a base 10, a seat 20, a backrest 30, a footrest 40, and a linkage mechanism 50. The base 10 is connected to the seat 20, and the seat 20 is connected to the backrest 30 and the footrest 40 via the linkage mechanism 50. A drive component 72 (such as an electric push rod) is provided between the base 10 and the linkage mechanism 50. The drive component 72 is electrically connected to an electronic control module 70. The electronic control module 70 is used to control the operation of the drive component 72, which drives the linkage mechanism 50 to move, thereby adjusting the angle between the seat 20, the backrest 30, and the footrest 40.

[0040] It should be noted that the base 10, seat 20, backrest 30, and footrest 40 of the sofa body are connected by a linkage mechanism 50. The drive unit 72 and the electronic control module 70 work together to adjust the angle between the seat 20, backrest 30, and footrest 40. This application provides users with a comfortable sitting posture suitable for multiple scenarios through the combination of mechanical transmission and intelligent control, while optimizing the effect of the massage mechanism 35. Specifically, the base 10 serves as a supporting base, and anti-slip pads (such as rubber material) can be installed on the bottom. The linkage mechanism 50 can be a linkage mechanism, including a base linkage 51, a seat linkage 52, a backrest linkage 53, and a footrest linkage 54. The base linkage 51 is connected to the base 10, the seat linkage 52 is connected to the seat 20, the backrest linkage 53 is connected to the backrest 30, and the footrest linkage 54 is connected to the footrest 40. The connection can be direct or through a connector 55.

[0041] Users select a seating mode (such as office mode, leisure mode, reclining mode, etc.) via the manual control module 71, which generates a corresponding control signal. After receiving the control signal, the electronic control module 70 calculates the target position of the drive component 72 (e.g., a 100mm electric push rod stroke) based on preset linkage logic (e.g., the correspondence between the backrest angle of 30° and the extension length of the footrest 40°). The electronic control module 70 controls the movement of the drive component 72 via a PWM signal (e.g., the electric push rod extends at a speed of 8mm / s), while simultaneously monitoring the position feedback of the drive component 72 in real time (e.g., via a potentiometer or encoder), achieving closed-loop control. The design, which uses the linkage mechanism 50 and the electronic drive to adjust the sofa's angle, combines the reliability of mechanical transmission with the flexibility of intelligent control. This not only provides users with a comfortable seating posture adaptable to multiple scenarios but also improves the user experience through the synergistic optimization of seating posture and massage functions.

[0042] As one possible implementation method, such as Figure 5 As shown, the foot support 40 is connected to the linkage mechanism 50 via a pivot 42. An elastic element 43 is provided between the foot support 40 and the linkage mechanism 50. The elastic element 43 is used to drive the foot support 40 to move toward the side away from the linkage mechanism 50.

[0043] It should be noted that the foot support 40 (such as the foot support plate 41) is connected to the linkage mechanism 50 via a rotating shaft 42. The axis of the rotating shaft 42 coincides with the rotation center of the foot support 40. One end of the elastic element 43 is hinged to the foot support plate 41 of the foot support 40, and the other end is hinged to the foot support connecting rod 54 of the linkage mechanism 50. When the driving element 72 (such as an electric push rod) pushes the active rod of the linkage mechanism 50, it can drive the driven rod to rotate. The driven rod drives the foot support 40 to rotate around the center of the rotating shaft 42, thereby extending or retracting the foot support 40. When the foot support 40 contacts the user's foot, the user applies pressure to the foot support 40, the elastic element 43 is compressed (or the torsion spring is twisted), generating a reverse elastic force, which drives the foot support 40 to move away from the linkage mechanism 50, adaptively conforming to the curve of the user's foot, while buffering the contact impact, thus preventing pinching injuries.

[0044] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the seat portion 20 and / or the backrest 30 are provided with a receiving space 33, and the traveling rack 34 is installed in the receiving space 33. For example, in this embodiment, the traveling rack 34 is installed vertically inside the backrest 30, and there are two traveling racks 34. The two ends (e.g., top and bottom) of the two traveling racks 34 on the same side are fixed by two connecting beams to ensure the stability of the traveling racks 34. The aforementioned limit switch 341 can be installed at the corresponding position of the connecting beam.

[0045] As one possible implementation method, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the seat part 20 includes a seat frame 21 and a seat cushion fixedly installed outside the seat frame 21. The backrest 30 includes a backrest frame 31 and a backrest cushion 32 fixedly installed outside the backrest frame 31. The backrest frame 31 may be provided with a connecting groove 311 to achieve a limiting connection with the backrest connecting rod 53. The seat frame 21 and / or the backrest frame 31 are provided with hooks 23 on opposite sides, and an elastic support 24 is provided between the two hooks 23.

[0046] It should be noted that, for example, in this embodiment, the seat frame 21 is symmetrically equipped with hanging members 23 on both the left and right sides, and the backrest frame 31 is symmetrically equipped with hanging members 23 on both the upper and lower sides. The opposite ends of the elastic support member 24 are connected to the hanging members 23. Furthermore, the support and fit can be improved by using a tightening strap 25. When the user sits down, their weight is transmitted to the base 10 through the seat upholstery, the hanging members 23 of the seat frame 21, and the elastic support member 24. The elastic support member 24 deforms under compression, dispersing the concentrated pressure to the entire seat area. When the user leans back, the back pressure is transmitted to the linkage mechanism 50 through the backrest upholstery 32, the hanging members 23 of the backrest frame 31, and the elastic support member 24. The elastic support member 24 deforms under stretching, buffering the impact of leaning back, and providing back support through elastic rebound. In this way, through the combination of mechanical elastic buffering and ergonomics, the pressure of the human body is effectively dispersed, the impact of changes in sitting posture is absorbed, and the durability and comfort of the sofa are improved, bringing users a more comfortable sitting and lying experience.

[0047] As one possible implementation method, such as Figure 1 As shown, the sofa body also includes two armrests 60 located on the left and right sides of the seat 20. Each armrest 60 includes an armrest frame 61 and an armrest upholstery 62 fixedly mounted outside the armrest frame 61. The armrest frame 61 can be fixedly connected to the seat frame 21 via a fastener 611. At least one armrest 60 is provided with a bracket 63 for fixing electronic devices. Thus, while providing comfortable arm support through the armrests 60, the brackets 63 allow for convenient fixing of devices such as mobile phones and tablets, promoting the intelligent development of massage sofas.

[0048] As one possible implementation method, such as Figures 1 to 3 , Figure 5 and Figure 7 As shown, the seat frame 21, backrest frame 31, and armrest frame 61 are all blow-molded parts, such as those made of polymer materials using blow molding technology, so that the sofa can achieve any shape design, and can also achieve lightweight, high strength and low cost manufacturing of the frame. The seat upholstery, backrest upholstery 32, and armrest upholstery 62 all include covering parts 321 and filling material 322. The filling material 322 is filled in the covering parts 321, such as breathable linen covering high elastic sponge.

[0049] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0050] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
