A modular massage chair

Abstract

This invention provides a modular massage chair. The modular massage structure includes two armrests, each ergonomically designed, with multiple lifting mechanisms embedded within each armrest. The ends of these lifting mechanisms are connected to the top and bottom of the armrests, respectively. Multiple massage structures are positioned between the two armrests, with their ends connected to the lifting mechanisms on either side. This allows the massage structures to move up and down with the lifting mechanisms, providing a wave-like rolling massage to the torso and legs. By utilizing the lifting mechanisms corresponding to the multiple massage structures, the massage structures rise or fall, conforming to the torso and legs. This allows the massage structures to adjust according to the degree of contact with the body, enabling localized or full-body massage. The simultaneous or staggered operation of the multiple massage mechanisms allows for both continuous and staggered massage.

Description

Technical Field

[0001] This invention relates to the field of massage chair technology, and specifically to a modular massage chair. Background Technology

[0002] Massage mechanisms are typically fixed within massage chairs, using a mechanical core to massage the body. However, this core usually moves only within a fixed track, unable to adjust to the degree of contact between the massage mechanism and the body, thus lacking flexibility in track configuration. This prevents easy switching between full-body and localized massage. Therefore, a modular massage chair has been invented to address these issues. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing technology that the massage structure cannot be adjusted according to the degree of contact between the massage structure and the human body, and cannot realize the variability of the massage track, thereby providing a modular massage chair.

[0004] To address the above problems, the present invention provides a modular massage chair, comprising:

[0005] The armrests are ergonomically designed and consist of two armrests. Each armrest contains multiple lifting mechanisms, with their ends connected to the top and bottom of the armrest. Between the two armrests are multiple massage structures, with their ends connected to the lifting mechanisms on both sides. This allows the massage structures to move up and down with the lifting mechanisms, providing a wave-like rolling massage to the torso and legs.

[0006] In some embodiments, the massage structure includes a flipping mechanism that causes the massage structure to flip. The flipping mechanism includes a rotating base and two rotating wheels, which are rotatably connected. Two fixed seats are provided between the two rotating wheels. A first rotating rod is provided between the rotating wheel and the fixed seat on the same side. One end of the first rotating rod is rotatably connected to one side of the rotating wheel, and the other end of the first rotating rod rotatably passes through the fixed seat. A plurality of guide rods are provided between the two fixed seats, and the two ends of the plurality of guide rods are respectively connected to the other side of the fixed seat. A first transmission shaft is provided between the plurality of guide rods, and the two ends of the first transmission shaft are respectively connected to the other end of the first rotating rod. A first motor is fixedly mounted on the rotating base, and the output shaft of the first motor passes through the rotating base and is fixedly connected to the rotating wheel. The two rotating wheels are respectively fixedly connected to the lifting mechanisms on both sides.

[0007] In some embodiments, the massage structure further includes a horizontal traveling mechanism and a massage mechanism, both of which are mounted on a plurality of guide rods and the first drive shaft. The horizontal traveling mechanism drives the massage mechanism to reciprocate on the first drive shaft, and the massage mechanism provides wave-like rolling massage to the torso and legs. The horizontal traveling mechanism includes a fast traveling mechanism and a slow traveling mechanism, which are used to change the traveling speed of the massage mechanism on the first drive shaft. The fast traveling mechanism and the slow traveling mechanism are located on both sides of the guide rods and are slidably connected. The massage mechanism is slidably connected to the plurality of guide rods and screwed to the first drive shaft.

[0008] In some embodiments, the lifting mechanism includes a second drive shaft, one end of which is rotatably connected to the top of the armrest seat, and the other end of which is fixedly connected to the output end of a second motor disposed at the bottom of the armrest seat. Several through vertical grooves are opened on opposite sides of the two armrest seats, and connectors are respectively disposed in the vertical grooves. One end of each connector is screwed to the second drive shaft, and the other end of each connector is fixedly connected to the rotating seat through the vertical groove.

[0009] In some embodiments, the rapid travel mechanism includes a third motor, which is fixedly connected to one side of the rotating wheel. A gear is fixedly connected to the output end of the third motor, and a gear disk is also provided on the first rotating rod connected to the rotating wheel, with the gear disk meshing with the gear.

[0010] In some embodiments, the slow-moving mechanism includes a worm and two fixed plates. One end of each of the two fixed plates is connected to the outside of the rotating wheel. The worm is disposed between the two fixed plates. Both ends of the worm are connected to the output end of a fourth motor that is fixedly connected to the two fixed plates. A worm wheel that matches the worm is also disposed on the first rotating rod connected to the rotating wheel. The worm wheel meshes with the worm.

[0011] In some embodiments, the massage mechanism includes a connecting seat, a first mechanism, and a second mechanism. The first mechanism and the second mechanism are respectively disposed on both sides of the connecting seat. The connecting seat is slidably connected to a plurality of guide rods and screwed to the first transmission shaft. The first mechanism and the second mechanism are a pair. One end of the pair of first mechanisms is rotatably connected to the connecting seat, and the other end of each pair of first mechanisms is provided with a bionic finger. One end of the pair of second mechanisms is rotatably connected to the connecting seat, and the other end of each pair of second mechanisms is provided with a rolling wheel. A hydraulic cylinder is provided between the first mechanism and the second mechanism and the connecting seat. Both ends of the hydraulic cylinder are provided with connecting parts. The connecting part at one end of the hydraulic cylinder is rotatably connected to the connecting seat, and the connecting part at the other end of the hydraulic cylinder is rotatably connected to either the first mechanism or the second mechanism.

[0012] In some embodiments, a head massage device, a foot massage device, and a pneumatic module assembly are further provided between the two armrests. The head massage device is installed on the upper head for supporting the head, the foot massage device is installed on the foot support for supporting the feet, and the pneumatic module assembly includes a pair of arm-clamping airbags and a pair of leg-clamping airbags. The arm-clamping airbags are located in the middle of the two armrests to relax the arms, and the leg-clamping airbags are located in the lower part of the two armrests to relax the legs.

[0013] In some embodiments, the massage structure is covered with sponge leather.

[0014] In some embodiments, a control device is also provided on one side of the two armrests facing each other, and the control device is electrically connected to the plurality of massage structures.

[0015] The modular massage chair provided by this invention has the following beneficial effects:

[0016] 1. This invention features multiple lifting mechanisms installed within two armrest seats, with their ends connected to the top and bottom of the armrest seats respectively. Adapting to ergonomic design, the maximum height of each lifting mechanism is limited. Multiple massage structures are installed between the two armrest seats, with their ends connected to the lifting mechanisms on both sides. When the lifting mechanisms connected to both sides of the same massage structure operate simultaneously, the connected massage structure rises or falls, conforming to the body's torso and legs. This allows for a variable massage track, enabling the massage structure to adjust according to the degree of contact with the body. Local or full-body massage can also be achieved. Through the simultaneous or staggered operation of multiple corresponding massage mechanisms, full-time and staggered massage can be realized.

[0017] 2. This invention also achieves the reproduction of various massage techniques in traditional Chinese medicine by adjusting the opening and closing of a pair of first and second mechanisms, combined with the cooperation of bionic fingers and rolling wheels. With the help of the flipping mechanism, the massage technique can be changed after flipping. Through the mutual cooperation of the massage mechanism, flipping mechanism and horizontal movement mechanism corresponding to multiple massage structures, a variety of massage programs can be realized.

[0018] 3. The present invention also includes multiple massage structures between the two armrest seats, the massage structures being covered with sponge leather to enhance aesthetics and comfort. The sponge leather is designed to be removable, allowing it to be retained when the massage structure's mechanism is upgraded in the future, thus reducing resource waste. Attached Figure Description

[0027] like Figure 1-6As shown, this invention provides a modular massage structure, comprising: an armrest seat 22, which is ergonomically designed, and two armrest seats 22 are provided. Each armrest seat 22 contains multiple lifting mechanisms, with their ends respectively connected to the top and bottom of the armrest seat 22. Multiple massage structures are arranged between the two armrest seats 22, with their ends respectively connected to the lifting mechanisms on both sides, allowing the massage structures to move up and down with the lifting mechanisms, achieving a wave-like rolling massage of the torso and legs. Figure 5 and Figure 6 As shown, the armrests are ergonomically designed, offering both aesthetic appeal and comfort. Each armrest contains multiple lifting mechanisms, with their ends connected to the top and bottom of the armrest. The ergonomic design limits the maximum height of each lifting mechanism. Multiple massage structures are positioned between the two armrests, with their ends connected to the lifting mechanisms on either side. When the lifting mechanisms on both sides of the same massage structure operate simultaneously, the connected massage structure rises or falls, conforming to the body's torso and legs. This allows for a flexible massage track, adjusting the massage structure according to the degree of contact with the body. It can also provide localized or full-body massage. Through the simultaneous or staggered operation of multiple massage mechanisms, full-time and staggered massage are possible.

[0028] In some embodiments, the massage structure includes a flipping mechanism that flips the massage structure. The flipping mechanism includes a rotating base 1 and two rotating wheels 2, which are rotatably connected. Two fixed seats 3 are disposed between the two rotating wheels 2. A first rotating rod 4 is disposed between the rotating wheels 2 and the fixed seats 3 on the same side. One end of the first rotating rod 4 is rotatably connected to one side of the rotating wheel 2, and the other end of the first rotating rod 4 rotatably passes through the fixed seat 3. A plurality of guide rods 5 are disposed between the two fixed seats 3, with both ends of the guide rods 5 connected to the other side of the fixed seats 3. A first transmission shaft 6 is disposed between the guide rods 5, with both ends of the first transmission shaft 6 connected to the other end of the first rotating rod 4. A first motor 7 is fixedly mounted on the rotating base 1, and the output shaft of the first motor 7 passes through the rotating base 1 and is fixedly connected to the rotating wheels 2. The two rotating wheels 2 are respectively fixedly connected to the lifting mechanisms on both sides. Figure 1-4As shown, the massage structure includes a flipping structure that allows the massage structure to flip, enabling structures located on the back or front side of the massage structure to flip. The flipping mechanism includes a rotating base and rotating wheels, which are rotatably connected, allowing the structure connected to the rotating wheels to flip. A first motor is fixedly mounted on the rotating base, driving the rotating wheels connected to the output shaft to rotate, thus achieving the flipping. The two first motors of the same massage structure rotate in opposite directions, but have the same power; changing the rotation direction of the motors changes the flipping direction. Two fixed seats are provided between the structures formed by the two sets of rotating bases and rotating wheels. A first rotating rod is provided between the rotating wheels and the fixed seats, with one end rotatably connected to the rotating wheel and the other end rotatably passing through the fixed seat. Several guide rods and a first drive shaft are provided between the fixed seats, with the other ends of the two first rotating rods connected to both sides of the first drive shaft. The two rotating wheels are fixedly connected to lifting mechanisms on both sides, allowing the lifting mechanisms on both sides to raise and lower the massage structure.

[0029] In some embodiments, the massage structure further includes a horizontal traveling mechanism and a massage mechanism, both of which are mounted on a plurality of guide rods 5 and the first drive shaft 6. The horizontal traveling mechanism drives the massage mechanism to reciprocate on the first drive shaft 6, providing a wave-like rolling massage to the torso and legs. The horizontal traveling mechanism includes a fast traveling mechanism and a slow traveling mechanism, which are used to change the traveling speed of the massage mechanism on the first drive shaft 6. The fast and slow traveling mechanisms are located on both sides of the guide rods 5 and are slidably connected. The massage mechanism is slidably connected to the plurality of guide rods 5 and screwed to the first drive shaft 6. Figure 1-5 As shown, the massage structure also includes a horizontal traveling mechanism and a massage mechanism. The horizontal traveling mechanism drives the massage mechanism to reciprocate on the first transmission shaft. By changing the rotation direction of the driving device, the reciprocating motion is achieved. The massage mechanism provides a wave-shaped rolling massage to the torso and legs. The horizontal traveling mechanism includes a fast traveling mechanism and a slow traveling mechanism to change the traveling speed of the massage mechanism on the first transmission shaft. The fast traveling mechanism and the slow traveling mechanism are located on both sides of the guide rod and are slidably connected. The massage mechanism is slidably connected to several guide rods and screwed to the first transmission shaft, which causes the massage mechanism to reciprocate.

[0030] In some embodiments, the lifting mechanism includes a second drive shaft 8, one end of which is rotatably connected to the top of the armrest seat 22, and the other end of which is fixedly connected to the output end of a second motor 9 disposed at the bottom of the armrest seat 22. Each of the two armrest seats 22 has several through vertical grooves 23 on opposite sides. Connectors are respectively disposed within the vertical grooves 23, one end of which is screwed to the second drive shaft 8, and the other end of which is fixedly connected to the rotating seat 1 through the vertical groove 23. Figure 5 and Figure 6 As shown, the lifting mechanism includes a second drive shaft. One end of the second drive shaft is rotatably connected to the top of the armrest seat, and the other end is fixedly connected to the output end of the second motor at the bottom of the armrest seat. Several through vertical grooves are opened on opposite sides of the two armrest seats. Connecting parts are set in the vertical grooves. The second drive shaft is screwed to one end of the connecting part, and the other end is connected to the rotating seat outside the vertical groove. The second motor rotates in the forward or reverse direction. The power of the second motor is the same. The two second motors corresponding to the same lifting mechanism rotate in opposite directions, thereby realizing the massage structure rising or falling on the second drive shaft of the two lifting mechanisms.

[0031] In some embodiments, the rapid travel mechanism includes a third motor 10, which is fixedly connected to one side of the rotating wheel 2. A gear 11 is fixedly connected to the output end of the third motor 10. A gear disk 12 is also provided on the first rotating rod 4 connected to the rotating wheel 2, and the gear disk 12 meshes with the gear 11. Figure 1 , Figure 2 and Figure 5 As shown, the rapid travel mechanism includes a third motor, which is fixedly connected to one side of the rotating wheel. The output end of the third motor is fixedly connected to a gear, which meshes with a gear disk on the first rotating rod. The motor rotates in the forward or reverse direction, causing the gear to drive the meshing gear disk to rotate in the forward or reverse direction. The number of teeth on the gear is much smaller than the number of teeth on the gear disk, thereby achieving speed increase.

[0032] In some embodiments, the slow-moving mechanism includes a worm gear 14 and two fixed plates 13. One end of each fixed plate 13 is connected to the outside of the rotating wheel 2. The worm gear 14 is positioned between the two fixed plates 13. Both ends of the worm gear 14 are connected to the output ends of a fourth motor 28 fixedly connected to the two fixed plates 13. A worm wheel 15, matching the worm gear 14, is also provided on the first rotating rod 4 connected to the rotating wheel 2. The worm wheel 15 meshes with the worm gear 14. Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the slow-moving mechanism includes a worm gear and two fixed plates. The two fixed plates are fixedly connected to the outside of the rotating wheel. The worm gear is positioned between the fixed plates, and both ends of the worm gear are connected to the output ends of a fourth motor fixedly connected to the two fixed plates. A worm wheel matching the worm gear is also provided on the first rotating rod connected to the rotating wheel. The two fourth motors rotate in opposite directions and have the same power. They rotate in the forward or reverse direction, causing the worm gear to drive the worm wheel to rotate. Due to the difference in the number of teeth between the worm wheel and the worm gear, a slow speed is achieved, thus enabling the connected massage mechanism to move slowly.

[0033] In some embodiments, the massage mechanism includes a connecting seat 16, a first mechanism 17, and a second mechanism 18. The first mechanism 17 and the second mechanism 18 are respectively disposed on both sides of the connecting seat 16. The connecting seat 16 is slidably connected to a plurality of guide rods 5 and screwed to the first transmission shaft 6. The first mechanism 17 and the second mechanism 18 are a pair. One end of the pair of first mechanisms 17 is rotatably connected to the connecting seat 16, and the other end of each pair of first mechanisms 17 is provided with a bionic finger 19. One end of the pair of second mechanisms 18 is rotatably connected to the connecting seat 16, and the other end of each pair of second mechanisms 18 is provided with a rolling wheel 20. A hydraulic cylinder 21 is disposed between the first mechanism 17 and the second mechanism 18 and the connecting seat 16. Both ends of the hydraulic cylinder 21 are provided with connecting parts. The connecting part at one end of the hydraulic cylinder 21 is rotatably connected to the connecting seat 16, and the connecting part at the other end of the hydraulic cylinder 21 is rotatably connected to either the first mechanism 17 or the second mechanism 18. Figure 1 , Figure 3 and Figure 5 As shown, the massage mechanism includes a connecting seat, a first mechanism, and a second mechanism. The first and second mechanisms are located on opposite sides of the connecting seat. The connecting seat is slidably connected to a guide rod and screwed to a first drive shaft. The first and second mechanisms are a pair. One end of each of the first and second mechanisms is rotatably connected to the connecting seat, and the other end is respectively equipped with a bionic finger and a rolling wheel. A hydraulic cylinder is provided between the first and second mechanisms and the connecting seat. Both ends of the hydraulic cylinder are provided with connecting parts. The connecting part at one end of the hydraulic cylinder is rotatably connected to the connecting seat, and the connecting part at the other end of the hydraulic cylinder is rotatably connected to either the first or second mechanism. This allows the opening and closing of the pair of first and second mechanisms to be adjusted by the hydraulic cylinder. Combined with the cooperation of the bionic finger and the rolling wheel, various massage techniques from traditional Chinese medicine can be reproduced. With the help of a flipping mechanism, the massage technique can be changed after flipping.

[0034] In some embodiments, a head massage device 24, a foot massage device, and a pneumatic module assembly 26 are further provided between the two armrest seats 22. The head massage device 24 is installed on the upper head for supporting the head, and the foot massage device 25 is installed on the foot support for supporting the feet. The pneumatic module assembly 26 includes a pair of arm-clamping airbags and a pair of leg-clamping airbags. The arm-clamping airbags are located in the middle of the two armrest seats 22 to relax the arms, and the leg-clamping airbags are located at the lower part of the two armrest seats 22 to relax the legs. Figure 5 and Figure 6 As shown, a head massage device, a foot massage device, and a pneumatic module assembly are respectively installed between the two armrests. The head massage device is installed on the upper part of the armrest to support the head, and the foot massage device is installed on the footrest to support the feet. The pneumatic module assembly includes a pair of arm-clamping airbags and a pair of leg-clamping airbags. The arm-clamping airbags are located in the middle of the two armrests to relax the arms, and the leg-clamping airbags are located at the bottom of the two armrests to relax the legs. Compressed air is delivered into the airbags through an external compressed air device, and the airbags are intermittently delivered or released to form the expansion and contraction of the airbags, thus relaxing the arms or legs.

[0035] In some embodiments, the massage structure is covered with sponge leather. For example... Figure 6 As shown, the massage structure is covered with sponge leather, which enhances its appearance and comfort. The sponge leather is designed to be removable, allowing it to be retained when the massage mechanism is upgraded in the future, thus reducing resource waste.

[0036] In some embodiments, a control device 27 is also provided on one side of each of the two armrest seats 22, and the control device 27 is electrically connected to the plurality of massage structures. For example... Figure 6 As shown, the control device operates the first motor, second motor, third motor, fourth motor, hydraulic cylinder, and other devices in the operating device. These devices are activated or deactivated and their direction changed when needed to complete the massage. By controlling the lifting mechanisms corresponding to multiple massage structures, the massage tracks and postures of the massage structures can be adjusted, allowing for full-body or partial massage. The control device can be used to set corresponding control programs, combined with the user's preferences, to control multiple massage structures to operate simultaneously or at different times. Furthermore, based on the coordination of the massage mechanisms, flipping mechanisms, and horizontal travel mechanisms corresponding to the multiple massage structures, especially the two massage cores of the massage mechanism, a personalized massage program can be designed.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention.
