Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically a leg-flipping structure for a massage chair. Background Technology

[0002] Existing massage chairs typically only offer single calf or foot massage functions, making it difficult for the two to work together and resulting in an unsatisfactory massage experience. Furthermore, the lifting mechanisms in traditional leg massage structures are often simple rotating shafts with limited lifting angles, failing to elevate the calves to a higher position. This leads to insufficient stretching of the fascia on the back of the thighs and calves, negatively impacting leg shaping effects.

[0003] Therefore, we propose a leg-flipping structure for massage chairs to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a leg-flipping structure for a massage chair to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leg-shaping flipping structure on a massage chair, comprising: a support frame, wherein a leg massage structure is rotatably mounted on the upper part of the support frame, and a foot massage structure is mounted on the lower part of the support frame;

[0006] The leg massage structure includes a rotating lifting bracket, which is connected to the upper end of the support frame via a hinge. Side massage plates are symmetrically fixed on both sides of the rotating lifting bracket, and a central dynamic massage structure is installed in the middle of the rotating lifting bracket.

[0007] The central dynamic massage structure includes a carrier plate, which is fixedly installed in the middle position of the rotating lifting bracket.

[0008] The back of the carrier plate is connected to a linear electric actuator, which drives the carrier plate and the rotating lifting bracket to rotate and lift by telescopic movement.

[0009] The hinge includes a first fixed plate and a second fixed plate. The first fixed plate is fixedly installed on the support frame, and the second fixed plate is fixedly connected to the side massage plate. The first fixed plate is rotatably connected to one end of the first hinge arm and the first limiting hinge arm. The other end of the first hinge arm is rotatably connected to one end of the second hinge arm. The other end of the second hinge arm is rotatably connected to the fixed hinge arm. The fixed hinge arm is fixedly connected to the second fixed plate.

[0010] The other end of the first limiting hinge arm is rotatably connected to one end of the second limiting hinge arm, and the other end of the second limiting hinge arm is rotatably connected to the fixed hinge arm.

[0011] Preferably, a motor is fixedly mounted on the carrier plate, and the motor is driven by a gearbox and connected to an output shaft. Eccentric wheels are fixedly mounted at both ends of the output shaft, and the eccentric wheels are rotatably connected to the dynamic massage plate through bearings.

[0012] Preferably, airbags are provided on both sides and the inner side of the central dynamic massage plate, and the airbags are connected to an air pump.

[0013] Preferably, the dynamic massage plate is also rotatably connected to one end of a limiting link, and the other end of the limiting link is rotatably connected to a positioning shaft, which is fixedly mounted on the carrier plate.

[0014] Preferably, the foot massage structure includes a foot support frame, on which a drive unit is fixedly installed. The drive unit is driven to connect to a first drive shaft, which is rotatably mounted on the foot support frame. The two ends of the first drive shaft are driven to connect to two second drive shafts via a belt pulley transmission assembly, which are rotatably mounted on the foot support frame.

[0015] Preferably, a plurality of massage rollers are fixedly installed on both the first and second drive shafts, and the surface of the massage rollers is provided with massage protrusions.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By rotating and mounting the leg massage structure on the upper part of the support frame and the foot massage structure on the lower part, the two are arranged vertically in the normal state, which can massage the calf and foot at the same time, providing a continuous massage experience; when it is necessary to assist in calf flexion and extension, the foot can be naturally detached from the foot massage structure, and the leg massage structure can be rotated and lifted to achieve passive calf flexion and extension training, which is convenient to use.

[0018] 2. The hinged connection between the rotating lifting bracket and the support frame allows the rotating lifting bracket to have a much larger range of motion than the traditional rotating shaft structure, which can lift the lower leg to a higher position, effectively stretching the fascia on the back of the thigh and calf, and enhancing the leg shaping effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a leg-shaping flipping structure on a massage chair, comprising: a support frame 1, a leg massage structure 2 rotatably mounted on the upper part of the support frame 1, and a foot massage structure 3 mounted on the lower part of the support frame 1. In a normal state, the leg massage structure 2 is perpendicular to the foot massage structure 3, and can massage the calf and foot simultaneously. When assisting in flexion and extension of the calf, the foot disengages from the foot massage structure 3, and the flexion and extension of the calf can be assisted by the rotational lifting of the leg massage structure 2.

[0028] The leg massage structure 2 includes a rotating lifting bracket 21, which is connected to the upper end of the support frame 1 via a hinge 23. Side massage plates 24 are symmetrically fixed on both sides of the rotating lifting bracket 21, and a central dynamic massage structure 22 is installed in the middle of the rotating lifting bracket 21. The calf part is kneaded and massaged by the cooperation of the central dynamic massage structure 22 and the side massage plates 24.

[0029] The central dynamic massage structure 22 includes a carrier plate, which is fixedly installed in the middle of the rotating lifting bracket 21. A motor 221 is fixedly installed on the carrier plate. The motor 221 is driven by a gearbox 222 and connected to an output shaft 223. Eccentric wheels 224 are fixedly installed at both ends of the output shaft 223. The eccentric wheels 224 are rotatably connected to the central dynamic massage plate 25 through bearings. The central dynamic massage plate 25 is also rotatably connected to one end of a limiting link 225. The other end of the limiting link 225 is rotatably connected to a positioning shaft 226. The positioning shaft 226 is fixedly installed on the carrier plate.

[0030] The output shaft 223 is driven to rotate by the motor 221 and the gearbox 222, which in turn drives the eccentric wheel 224 to rotate. The eccentric wheel 224, with the help of bearings, drives one end of the central dynamic massage plate 25 to move. Through the restraint and limitation of the limiting link 225, the central dynamic massage plate 25 is fixed in trajectory, and works with the side massage plate 24 to knead and massage the calf.

[0031] A linear electric actuator is connected to the back of the carrier plate. The linear electric actuator drives the carrier plate and the rotating lifting bracket 21 to rotate and lift through extension and retraction. During this process, the hinge 23 folds and extends to limit the movement. At the same time, it enables the rotating lifting bracket 21 to have a larger range of motion than the traditional rotating structure, which can lift the lower leg to a higher position and stretch the fascia on the back of the thigh and lower leg.

[0032] The hinge 23 includes a first fixing plate 231 and a second fixing plate 232. The first fixing plate 231 is fixedly installed on the support frame 1, and the second fixing plate 232 is fixedly connected to the side massage plate 24. The first fixing plate 231 is rotatably connected to one end of the first hinge arm 233 and the first limiting hinge arm 236. The other end of the first hinge arm 233 is rotatably connected to one end of the second hinge arm 234. The other end of the second hinge arm 234 is rotatably connected to the fixed hinge arm 235. The fixed hinge arm 235 is fixedly connected to the second fixing plate 232.

[0033] The other end of the first limiting hinge arm 236 is rotatably connected to one end of the second limiting hinge arm 237, and the other end of the second limiting hinge arm 237 is rotatably connected to the fixed hinge arm 235.

[0034] like Figure 6As shown, when folded, the first fixed plate 231 and the second fixed plate 232 are perpendicular, and each hinge arm is in a folded state. When extended, the first hinge arm 233 rotates counterclockwise relative to the first fixed plate 231, the second hinge arm 234 rotates clockwise relative to the first hinge arm 233, the fixed hinge arm 235 rotates counterclockwise relative to the second hinge arm 234, the first limiting hinge arm 236 rotates counterclockwise relative to the first fixed plate 231, the second limiting hinge arm 237 rotates clockwise relative to the first limiting hinge arm 236, and the second limiting hinge arm 237 rotates counterclockwise relative to the fixed hinge arm 235. The second fixed plate 232 and the first fixed plate 231 eventually tend to be on the same vertical plane, so that the second fixed plate 232 has a larger range of motion and is raised to a certain height, so that the side massage plate 24 is raised to a certain height, and thus the entire rotating lifting bracket 21 is raised to a certain height.

[0035] Airbags 26 are provided on the inner side of the side massage plate 24 and on both sides of the central dynamic massage plate 25. The airbags 26 are connected to an air pump. Through the contraction and expansion of the airbags 26, a squeezing and relaxing massage effect is achieved on the legs.

[0036] The foot massage structure 3 includes a foot support frame 31, a drive unit 32 is fixedly installed on the foot support frame 31, the drive unit 32 drives and connects to a first drive shaft 33, the first drive shaft 33 is rotatably mounted on the foot support frame 31, and the two ends of the first drive shaft 33 are connected to two second drive shafts 34 through a belt pulley drive assembly 36, the second drive shafts 34 are rotatably mounted on the foot support frame 31;

[0037] Several massage rollers 35 are fixedly installed on the first drive shaft 33 and the second drive shaft 34. Massage rollers 35 have massage protrusions on their surfaces.

[0038] The drive unit 32 drives the first drive shaft 33 to rotate, which in turn drives the other two second drive shafts 34 to rotate via the belt pulley drive assembly 36, thereby driving multiple massage rollers 35 to rotate and provide roller pressure stimulation to the soles of the feet.

[0039] Working principle: In normal use, the leg massage structure 2 is perpendicular to the foot massage structure 3. The user can place their calf in the leg massage structure 2 and their foot in the foot massage structure 3 to achieve synchronous massage of the calf and foot. When assisted calf flexion and extension is needed, the user removes their foot from the foot massage structure 3 and activates the linear electric actuator. The linear electric actuator extends and retracts, driving the carrier plate to rotate and lift the rotating lifting bracket 21 around the hinge 23, thereby raising the side massage plate 24 and the entire rotating lifting bracket 21 to a higher position to assist calf flexion and extension and stretch the fascia on the back of the thigh and calf.

[0040] During calf massage, the motor 221 of the central dynamic massage structure 22 starts and drives the output shaft 223 to rotate through the gearbox 222. The eccentric wheels 224 at both ends of the output shaft 223 rotate accordingly. The eccentric wheels 224 drive one end of the central dynamic massage plate 25 to move through the bearing. At the same time, one end of the limiting link 225 is rotatably connected to the central dynamic massage plate 25, and the other end rotates around the positioning shaft 226 to limit the movement trajectory of the central dynamic massage plate 25, so that it reciprocates along a fixed trajectory. In conjunction with the side massage plates 24 fixed on both sides, it performs kneading and pressing massage on the calf.

[0041] During foot massage, the drive unit 32 of the foot massage structure 3 is activated, driving the first drive shaft 33 to rotate. The first drive shaft 33 drives two second drive shafts 34 to rotate synchronously through the belt pulley transmission components 36 at both ends. Multiple massage rollers 35 fixed on the first drive shaft 33 and the second drive shaft 34 rotate accordingly. The massage protrusions on the surface of the massage rollers 35 roll and stimulate the sole of the foot, thus achieving foot massage.
