DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figures 1 to 15 , the present invention provides a technical solution.

[0017] A multifunctional massage sofa comprises a sofa seat 1, a leg support assembly is installed at the front end of the sofa seat 1, the leg support assembly comprises a leg support main seat 3 and an adjustment slide 20, the adjustment slide 20 is slidably connected to the surface of the leg support main seat 3, an installation cavity 37 is opened on the inner surface of the adjustment slide 20, a massage assembly is installed in the installation cavity 37, a cover cloth 28 for covering the installation cavity 37 is arranged on the surface of the leg support main seat 3, an extended cover cloth 30 is installed on the surface of the fixed frame 29, and the extended cover cloth 30 is used to cover the area of ​​the installation cavity 37 that the cover cloth 28 cannot cover; When the user of the massage sofa has long legs, the slidable adjustment slide 20 is provided to slide and adjust the position of the massage component installed in the adjustment slide 20 to adapt to the characteristic of the user's long legs, which is beneficial to improving the applicability of the massage sofa. In addition, by providing a cover cloth 28 and an extension cover cloth 30, under normal circumstances, the cover cloth 28 can cover the installation cavity 37 to prevent the massage component from being exposed and affecting the use. However, when the adjustment slide 20 slides, the cover cloth 28 cannot cover the area where the installation cavity 37 is exposed due to the sliding of the adjustment slide 20. At this time, the extended cover cloth 30 will cover the exposed area of ​​the installation cavity 37.

[0018] The side edges of the covering cloth 28 are fixedly connected to the surface of the leg support main seat 3, and the surface of the leg support main seat 3 is fixedly connected to two fixed frames 29, which respectively fix the upper and lower edges of the covering cloth 28, and the surface of the adjusting slide 20 is provided with an avoidance groove 36 for the fixed frames 29 to be embedded. Such an arrangement can not only enable the covering cloth 28 to be smoothly unfolded, but also ensure that when the adjusting slide 20 slides, it will not cause collision with the covering cloth 28 and the fixed frames 29, thereby maintaining the unfolded state of the covering cloth 28.

[0019] The surface of the adjusting slide 20 is rotatably connected to the cloth roller 31, and the extended cloth 30 is wound around the surface of the cloth roller 31, and one end of the extended cloth 30 is fixedly connected to the surface of the fixed frame 29. Through such a configuration, when the adjusting slide 20 slides, it will drive the extended cloth 30 and the cloth roller 31 to move together, and because one end of the extended cloth 30 is fixedly connected to the fixed frame 29, during the movement, the extended cloth 30 will cause the cloth roller 31 to rotate, thereby realizing the unwinding operation, so that the extended cloth 30 is used to cover the area where the installation cavity 37 is exposed due to the sliding of the adjusting slide 20, and the exposed area of ​​the installation cavity 37 is covered by unwinding the extended cloth 30. This configuration also has another significant advantage. When the adjusting slide 20 slides, the extended cloth 30 will gradually cover the exposed area of ​​the installation cavity 37 by unwinding, rather than moving as a whole, thereby effectively avoiding severe friction on the user's body.

[0020] One end of the cloth-covering roller 31 is coaxially fixedly connected with a linkage shaft 32, and the linkage shaft 32 is rotatably connected to the adjusting slide 20. An active cavity 35 is provided inside the adjusting slide 20, and an elastic reset component is arranged in the active cavity 35. The elastic reset component is used to reset the linkage shaft 32. The elastic reset component includes a drawstring 33 and a reset spring 34. One end of the reset spring 34 is fixedly connected to the adjusting slide 20, and the other end of the reset spring 34 is fixedly connected to one end of the drawstring 33, and the other end of the drawstring 33 is fixedly connected to the linkage shaft 32. The adjusting slide 20 slides so that the extended cloth-covering roller 31 is extended. The cloth 30 is unwound, and then the cloth covering roller 31 rotates, which will drive the linkage shaft 32 to rotate. The rotation of the linkage shaft 32 will cause the drawstring 33 to be wrapped around the surface of the linkage shaft 32. When the drawstring 33 is wrapped, the reset spring 34 is stretched, causing the reset spring 34 to produce elastic deformation, thereby storing elastic potential energy. When the adjustment slide 20 is reset and moved back, the elastic force of the reset spring 34 pulls the drawstring 33, causing the linkage shaft 32 to reverse. The reversal of the linkage shaft 32 causes the cloth covering roller 31 to reverse, so that the extended cloth covering 30 is wrapped around the cloth covering roller 31 again for winding, which helps to prevent the extended cloth covering 30 from spreading.

[0021] The front end surface of the sofa seat 1 is provided with a storage groove 2 for storing the leg support assembly. The front end surface of the sofa seat 1 is provided with a first slide groove 11. An unfolding connecting rod assembly is slidably arranged in the first slide groove 11. The unfolding connecting rod assembly is used to drive the leg support assembly to move. The leg support assembly is driven to move in and out of the storage groove 2 by the arranged unfolding connecting rod assembly. When the user needs to use the leg support assembly, the leg support assembly can be moved out. When it is not needed, the leg support assembly is stored in the storage groove 2, allowing the user to use the function of the sofa normally.

[0022] The unfolding connecting rod assembly includes a leg support connecting rod 6, an angle adjustment connecting rod 7, a connecting rod connecting block 8 and a connecting rod driving seat 9. The leg support connecting rod 6 is fixedly connected to the bottom end of the leg support main seat 3, one end of the angle adjustment connecting rod 7 is rotatably connected to the leg support connecting rod 6, and the other end of the angle adjustment connecting rod 7 is rotatably connected to the connecting rod connecting block 8, and the connecting rod connecting block 8 is fixedly connected to the connecting rod driving seat 9. Through such an arrangement, when the leg support assembly moves out of the storage slot 2 and the angle adjustment connecting rod 7 moves out of the first sliding slot 11, the angle adjustment connecting rod 7 is rotated by rotating the end of the connection between the angle adjustment connecting rod 7 and the connecting rod connecting block 8 to make the angle adjustment connecting rod 7 rotate upward. At this time, since the other end of the leg support assembly is naturally grounded under the action of gravity, the leg support connecting rod 6 and the angle adjustment connecting rod 7 rotate, thereby making the leg support main seat 3 tilted, which is convenient for the user to put his legs on the leg support assembly. The user can also adjust the inclination angle of the leg support main seat 3 by adjusting the upward flipping angle of the angle adjustment connecting rod 7 according to needs to obtain a more comfortable use experience.

[0023] A first motor 10 is installed on the surface of the connecting rod connecting block 8 , and an output end of the first motor 10 is fixedly connected to the angle adjustment connecting rod 7 . The angle adjustment connecting rod 7 is driven to rotate by starting the first motor 10 .

[0024] The front bottom edge of the leg support main seat 3 is rotatably connected to a roller 4. By providing the roller 4, when the angle of the leg support main seat 3 is adjusted, the friction between the bottom edge of the leg support main seat 3 and the ground is reduced.

[0025] A first screw rod 12 is rotatably connected in the first slide groove 11, and the first screw rod 12 movably penetrates the connecting rod driving seat 9, and the connecting rod driving seat 9 and the first screw rod 12 are threadedly connected. A second motor 13 is installed on the sofa seat 1, and the output end of the second motor 13 is coaxially fixedly connected to one end of the first screw rod 12. The first screw rod 12 is driven to rotate by starting the second motor 13. When the first screw rod 12 rotates, due to the threaded action between the first screw rod 12 and the connecting rod driving seat 9, the connecting rod driving seat 9 slides in the first slide groove 11, thereby causing the unfolding connecting rod assembly to slide in the first slide groove 11.

[0026] A protection pad 5 is provided on the front end surface of the leg support main seat 3 .

[0027] A sliding support plate 16 is fixedly connected to the surface of the adjusting slide 20, and a second slide groove 17 for the sliding support plate 16 to slide is provided on the surface of the leg support main seat 3. A second screw rod 18 is rotatably connected in the second slide groove 17 of the leg support main seat 3. The second screw rod 18 movably passes through the sliding support plate 16, and the second screw rod 18 and the sliding support plate 16 are threadedly connected. A third motor 19 is installed on the leg support main seat 3, and the output end of the third motor 19 is coaxially fixedly connected to one end of the second screw rod 18. The second screw rod 18 is driven to rotate by starting the third motor 19. When the second screw rod 18 rotates, due to the threaded action between the second screw rod 18 and the sliding support plate 16, the sliding support plate 16 slides in the second slide groove 17, so that the adjusting slide 20 is slidably connected to the surface of the leg support main seat 3.

[0028] Furthermore, the surface of the sliding support plate 16 is fixedly connected with an anti-slip slider 15, and the groove wall of the second slide groove 17 is cooperated with to open a limiting slide groove 14 for the anti-slip slider 15 to slide. By setting the anti-slip slider 15 to slide in the limiting slide groove 14, it is helpful to prevent the sliding support plate 16 from sliding out of the second slide groove 17.

[0029] An electric push rod 21 is installed in the installation cavity 37. The telescopic end of the electric push rod 21 is connected to the massage component. The electric push rod 21 is used to drive the massage component to move toward the user, which is beneficial for the user to adjust the massage strength of the massage component.

[0030] The massage assembly includes a massage rail 22, a massage movable seat 24, a massage connecting frame 25 and a massage roller 26. The massage rail 22 is slidably connected in the installation cavity 37, and the massage movable seat 24 is slidably connected to the surface of the massage rail 22. The massage movable seat 24 and the massage connecting frame 25 are fixedly connected, and the massage connecting frame 25 and the massage roller 26 are rollingly connected. The telescopic end of the electric push rod 21 is connected to the surface of the massage rail 22. By moving the massage movable seat 24, the massage roller 26 is driven to roll on the user's legs, thereby massaging the user's legs.

[0031] The surface of the massage slide rail 22 is rotatably connected with a third screw rod 23, and the third screw rod 23 movably penetrates the massage movable seat 24, and the third screw rod 23 and the massage movable seat 24 are threadedly connected. A fourth motor 27 is installed on the surface of the massage slide rail 22, and the output end of the fourth motor 27 is coaxially fixedly connected to one end of the third screw rod 23. The third screw rod 23 is driven to rotate by starting the fourth motor 27. When the third screw rod 23 rotates, due to the threaded action between the third screw rod 23 and the massage movable seat 24, the massage movable seat 24 is slidably connected to the surface of the massage slide rail 22.

[0032] The specific solution is as follows: when the leg support function of the massage sofa needs to be used, the second motor 13 installed on the sofa seat 1 is started, and its output end drives the first screw rod 12 to rotate. The rotation of the first screw rod 12 causes the connecting rod driving seat 9 to slide in the first sliding groove 11, thereby driving the unfolding connecting rod assembly to move and move the leg support assembly out of the storage groove 2.

[0033] Start the first motor 10, and its output end drives the angle adjustment link 7 to rotate. The angle adjustment link 7 rotates upward. Under the action of gravity at the other end of the leg support assembly, the leg support link 6 and the angle adjustment link 7 rotate, so that the leg support main seat 3 is tilted. The user can adjust the tilt angle of the leg support main seat 3 by adjusting the upward flip angle of the angle adjustment link 7 as needed to obtain a more comfortable use experience.

[0034] The user starts the third motor 19 installed on the leg support main seat 3 according to his own leg length, and its output end drives the second screw rod 18 to rotate. When the second screw rod 18 rotates, it drives the sliding support plate 16 to slide in the second slide groove 17, so that the adjusting slide 20 slides on the surface of the leg support main seat 3. When the adjusting slide 20 slides, it drives the extended cloth 30 wound on the surface of the cloth roller 31 and fixed on the fixed frame 29 at one end to move together with the cloth roller 31. Under the pull of the fixed frame 29, one end of the extended cloth 30 causes the cloth roller 31 to rotate to realize the unwinding operation, and accurately cover the installation cavity 37 area exposed due to the sliding of the adjusting slide 20. At the same time, the rotation of the cloth roller 31 drives the coaxially fixed linkage shaft 32 to rotate. The rotation of the linkage shaft 32 causes the drawstring 33 to be wrapped around its surface, stretching the reset spring 34 to make it produce elastic deformation and store elastic potential energy. In this way, the position of the massage component installed in the installation cavity 37 on the inner surface of the adjusting slide 20 can be adjusted to adapt to different leg lengths.

[0035] If the user needs to adjust the massage intensity, the user can start the electric push rod 21, and the telescopic end of the electric push rod 21 pushes the massage component connected to it to move toward the user.

[0036] The fourth motor 27 is started, and its output end drives the third screw rod 23 to rotate. The rotation of the third screw rod 23 causes the massage movable seat 24 to slide on the surface of the massage slide rail 22. By moving the massage movable seat 24, the massage roller 26 is driven to roll on the user's legs. Through the sliding of the massage movable seat 24 and the sliding of the adjustment slide 20, the massage roller 26 can roll along the surface of the user's calf to perform massage.
