Description

Technical Field

[0001] The utility model relates to the technical field of massage chairs, in particular to an assistive massage chair for standing up. Background Art

[0002] The existing massage chairs on the market have a large tilt angle on the backrest, which makes it inconvenient for users to get up and get off the machine after use. Especially for the elderly, whose physical functions have declined and their waist and abdomen strength are weak, it is difficult for them to get up after leaning on the backrest. They usually need to pull the side of the massage chair by hand.

[0003] The user has to use the board or other places to get up by leveraging force, which causes certain inconvenience to the user.

[0004] The utility model with existing application number 202220814828.0 discloses a massage chair, comprising a base frame, a seat frame mounted on the base frame, the rear end of the seat frame being hinged to the base frame via a first pin; a backrest assembly comprising a backrest bracket and a seat bracket, supported and mounted on the seat frame, the front end of which being hinged to the front end of the seat frame via a second pin; a reclining adjustment assembly comprising a first electric push rod, one end of which is hinged to the base frame and the other end is hinged to the seat frame, the first electric push rod driving the seat frame to rotate along the first pin; and a standing drive assembly comprising a second electric push rod, one end of which is hinged to the seat frame and the other end is hinged to the backrest assembly, the second electric push rod driving the backrest assembly to rotate along the second pin. In the above-mentioned massage chair, the reclining adjustment assembly can adjust the backrest's tilt angle, ensuring the user's sitting comfort and the massage needs of different tilt angles. The standing drive assembly can drive the backrest assembly to stand upright, making it convenient for the user to stand up and get off the massage chair after the massage is completed. The massage chair has a simple structure, is easy to use, and has a low cost.

[0005] However, although this patent achieves the goal of assisting the user to stand up and massage the back, the maximum angle of the back adjustment and the maximum angle of assisting standing up are still not large enough, and the stability of the entire chair frame is not strong. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a massage chair with strong stability, which can effectively realize zero-gravity massage and assist the human body to stand up, in view of the deficiencies of the above-mentioned existing technologies.

[0007] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: an assisted standing massage chair, comprising a base frame, a seat frame, a guide rail frame, and a calf support member, a calf linkage member for lifting or lowering the calf support member is provided between the calf support member and the base frame, a first electric cylinder is hingedly connected between the base frame and the guide rail frame, the seat frame comprises a seat portion and a backrest portion, a second electric cylinder is hingedly connected between the rear end of the seat portion and the guide rail frame, the guide rail frame and the calf support member are respectively hingedly matched with the front end of the seat portion, an extension rod arranged toward the base frame is fixedly provided at the bottom position of the seat portion near the rear end, and the extension rod is extended. A guide member is provided at the top of the rod, and an arc-shaped guide rail is fixed on the guide rail frame. When the second electric cylinder retracts, the rear end of the seat and the backrest move in the arc-shaped guide rail through the guide member to achieve guided falling and lying down. The first electric cylinder extends to lift the guide rail frame and the front end of the seat and enable the calf linkage member to push the calf support member and form a lying down state; the second electric cylinder enables the rear end of the seat and the backrest to move in the arc-shaped guide rail through the guide member to achieve guided lifting and standing up. The first electric cylinder retracts the guide rail frame to cause the front end of the seat to fall and the calf linkage member to stop pushing the calf support member and form a standing up state.

[0008] With the above technical solution, when the massage chair needs to be assisted to stand up, the program controls the first electric cylinder to be in the reset state, and the second electric cylinder reaches the maximum stroke. At this time, the massage chair is in the standing state, and the first electric cylinder, the seat frame and the base frame form a stable tripod structure, plus the calf linkage on the side supports the calf support member, so that the chassis of the entire massage chair is stable, and at the same time provides stable strength and stable support for the second electric cylinder when working, ensuring the stability of the platform. At this time, the angle between the backrest at the extension rod position and the ground can reach about 92°, and the minimum angle between the arc at the connection end of the seat and the backrest and the ground can reach about 79°. The angle between the upper end and the ground is about 90 degrees, which ensures that the human body does not fall forward. Compared with the inclination angle of the comparison document, it is more labor-saving, thereby more effectively assisting the human body to stand up straight; when the massage chair is massaging, the second electric cylinder is in the reset state, and the seat frame, guide frame and the second electric cylinder form a stable tripod structure, which not only ensures the strength of the platform but also has good stability, which can effectively achieve zero-gravity massage and assist the human body to stand up. The arc guide rails are fixed to both sides of the guide rail frame by welding or bolts. The arc guide rails can be set into a relative L-shape to prevent the guide parts from moving in the arc guide rails to achieve lying down or standing up on the upper part of the seat frame.

[0009] The cam is hinged to the bottom frame at one end and hinged to the guide rail frame at the other end, and the cam is hinged to the bottom frame at the other end and hinged to the guide rail frame at the other end. The cam is hinged to the bottom frame at one end and hinged to the guide rail frame at the other end, and the cam is hinged to the bottom frame at one end and hinged to the guide rail frame at the other end. The cam comprises a first linkage, a second linkage and a third linkage, the first end of the first linkage is hinged to the bottom frame, the second end is hinged to the second linkage, the second linkage is hinged to the middle section of the ejector away from the hinged first linkage, one end of the third linkage is hinged between the first end and the second end of the first linkage, and the other end is coaxially hinged with the ejector and the guide rail frame. When the first electric cylinder pushes the guide rail frame and lifts the front end of the seat, the first linkage lifts up and causes the second linkage and the third linkage to drive the ejector to push the calf support.

[0010] The second linkage member is configured to pass through the third linkage member so that the hinge points at both ends of the second linkage member are cross-connected to the ejector member and the first linkage member. When the push rod on the first electric cylinder extends and pushes up the guide rail frame, since the guide rail frame and the front end of the seat and the calf support member are hinged, the first electric cylinder is activated and simultaneously pushes the front end of the seat and one end of the calf support member to rise in height. Since the ejector member is hinged to the pushed end of the guide rail frame, the height of the ejector member also rises accordingly. Due to the cross-setting of the second linkage member and the third linkage member, the calf linkage member forms a clamping claw type that enables the ejector member and the first linkage member to be clamped or released at the same time. When the side of the ejector member hinged to the guide rail frame is lifted up, the distance between the ejector member and the first linkage member is increased, thereby causing the ejector member to push up the calf support member. When the side of the ejector member hinged to the guide rail frame falls, the distance between the ejector member and the first linkage member is reduced, thereby causing the ejector member to stop pushing up the calf support member and the calf support member to fall.

[0011] An assisted-standing massage chair can be further configured as follows: an ejection roller is provided on the top of the ejection member, and a support tube is provided on the side of the calf support member facing the base frame for the ejection roller to roll up and down along a track, and the ejection roller rolls up and down in the support tube and realizes the lifting or falling of the calf support member through the second linkage member and the third linkage member.

[0012] By adopting the above technical solution, the calf support is provided with a long groove with an upper opening on the side facing the base frame for the installation of the support tube, and the U-shaped groove of the support tube is used for the ejection roller to slide up and down. When the ejection roller is at the bottom of the support tube, the calf support is in the initial state, that is, the falling state. When the ejection roller is at the top of the support tube, the calf support is in the zero-gravity lying massage state, that is, the lifting state, and the calf support is lifted up or down by the ejection roller.

[0013] An assisted standing massage chair can be further configured as follows: the guide member is a guide roller, and the guide member slides along a track of the arc-shaped guide rail in the arc-shaped guide rail.

[0014] With the above technical solution, the curved guide rails are fixed to both sides of the guide rail frame by welding or bolts, so as not to interfere with the rotation of the seat frame when lying down or standing up. At the same time, the guide member can be moved in the curved guide rail to achieve the height change of the seat frame. The curved guide rail can be set into a U shape, and a baffle is set at its opening so that the roller always slides on the shape track defined by the curved guide rail when sliding, so that the guide member can still lift or fall the seat frame when moving in the curved guide rail.

[0015] An assisted standing massage chair can be further configured as follows: a buffer block is provided at the rear end of the seat, a buffer pad is provided on the guide rail frame for the buffer block to abut, and anti-slip teeth are provided on the buffer pad.

[0016] With the above technical solution, when the massage chair stands up, the buffer block moves away from the buffer pad. When the massage chair is in zero-gravity massage state or initial state, the buffer block will be against the buffer pad. The collision noise caused by metal against metal can be prevented by the two. The buffer pad can be made of rubber material, and the anti-slip teeth can increase the friction between the two when in contact, so that it is not easy for the two to slip when they are against each other, thereby making the contact more stable.

[0017] An assisted standing-up massage chair can be further configured as follows: a vertically arranged mounting rod is fixed on the base frame, a hinge point for hinged connection of the base frame and the guide rail frame is provided on the top of the mounting rod, when the horizontal plane where the rear end of the seat is located is level with the horizontal plane where the hinge point is located, it is in a lying state or a sitting state, and the buffer block abuts against the buffer pad; when the horizontal plane where the rear end of the seat is located is higher than the horizontal plane where the hinge point is located, it is in a standing-up state, and the buffer block is away from the buffer pad.

[0018] With the above technical solution, when the rear end of the seat is lifted by the second electric cylinder, the rear end of the seat is higher than the front end of the seat because the rear end of the seat frame is higher than the hinge point. At this time, the entire seat is also in a tilted state, and the human body is also in a posture that is easier to get up. When the rear end of the seat stops being lifted by the second electric cylinder, the rear end of the seat is level with the front end of the seat, so this is the initial state. When the first electric cylinder slightly lifts the front end of the seat, the rear end of the seat is lower than the front end of the seat, and this is the zero-gravity lying massage state. The three forms of the massage chair can be switched by the extension and retraction of the first electric cylinder and the second electric cylinder, and it is also relatively stable.

[0030] 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 embodiments described 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 making creative efforts shall fall within the scope of protection of the protection examples of the present invention.

[0031] Example: Figures 1-9The massage chair with auxiliary lifting function shown in the figure includes a base frame 1, a seat frame 2, a guide frame 3, and a calf support member 4. The base frame 1 and the guide frame 3 are hinged with a first electric cylinder 5, and the seat frame 2 and the guide frame 3 are hinged with a second electric cylinder 6. The seat frame 2 includes a seat portion 21 and a back portion 22. The guide frame 3 and the calf support member 4 are respectively hinged with the front end of the seat portion 21. A calf linkage member 40 is provided between the base frame 1 to lift or lower the calf support member 4. One end of the calf linkage member 40 is hinged with the base frame 1, and the other end is hinged with the guide frame 3. Figure 7As shown, the calf linkage 40 is hinged to the guide rail frame 3 at one end and is also hinged to a ejector 41 that rolls with the calf support member 4 to realize the lifting and falling of the calf support member 4. The top of the ejector 41 is provided with an ejector roller 42, and the calf support member 4 is provided with a support pipe 43 for the ejector roller 42 to roll up and down along the track on the side facing the base frame 1. The calf linkage 40 includes a first linkage 401, a second linkage 402 and a third linkage 403. The first end of the first linkage 401 is hinged to the base frame 1, and the second end is hinged to the second linkage 402. The second linkage 402 is hinged to the middle section of the ejector 41 at one end away from the hinged first linkage 401, and the third linkage 403 is hinged at one end. A linkage 410 is coaxially hinged between the first and second ends, and the other end is coaxially hinged with the ejector 41 and the guide rail frame 3. When the first electric cylinder 5 pushes the guide rail frame 3 and lifts the front end of the seat 21, the first linkage 401 is lifted and the second linkage 402 and the third linkage 403 drive the ejector 41 to push the calf support 4. The second linkage 402 and the third linkage 403 make the ejector 41 push the calf support 4. The ejection roller 42 rolls up and down in the support tube 43 and realizes the lifting or falling of the calf support 4 through the second linkage 402 and the third linkage 403. The second linkage 402 can pass through the third linkage 403 to realize the cross-setting of the hinge points at both ends. Connected to the ejector 41 and the first linkage 401, when the push rod on the first electric cylinder 5 extends and pushes up the guide rail frame 3, since the guide rail frame 3 and the front end of the seat 21 and the calf support member 4 are hinged, when the first electric cylinder 5 is started, it will also push the front end of the seat 21 and one end of the calf support member 4 to rise in height. Since the ejector 41 is hinged to the upper end of the guide rail frame 3, the height of the ejector 41 also rises accordingly. Due to the cross-arrangement of the second linkage 402 and the third linkage 403, the calf linkage 40 forms a clamping claw type that enables the ejector 41 and the first linkage 401 to be clamped or released at the same time. When the ejector 41 is lifted up on the hinged side of the guide rail frame 3, the ejector 41 and the first linkage 401 is enlarged, so that the ejector 41 pushes up the calf support 4. When the ejector 41 and the guide rail frame 3 are hinged on one side and fall down, the distance between the ejector 41 and the first linkage member 401 is reduced, so that the ejector 41 stops pushing the calf support 4, and the calf support 4 falls down. The bottom position of the seat 21 near the rear end is fixed with an extension rod 211 arranged toward the base frame 1, and the top of the extension rod 211 is provided with a guide member 212. The guide rail frame 3 is fixed with an arc-shaped guide rail 31. The guide member 212 is guided by the arc-shaped guide rail 31 to enable the seat frame 2 to lie down or stand up. The guide member 212 is a guide roller, and the guide member 212 slides along the shape track of the arc-shaped guide rail 31 in the arc-shaped guide rail 31.

[0032] like Figure 9As shown, the second electric cylinder 6 retracts and causes the rear end of the seat 21 and the support 22 to fall, and the first electric cylinder 5 pushes the guide rail frame 3 and causes the front end of the seat 21 to lift up, and the ejector 41 pushes the calf support 4 to form a lying state, as shown in FIG. Figure 1 and Figure 2 As shown, the second electric cylinder 6 pushes the rear end of the seat 21 and the backrest 22 to lift up, and the first electric cylinder 5 retracts the guide frame 3 and makes the ejector 41 stop pushing the calf support member 4 when the front end of the seat 21 falls to form a standing state. When the massage chair needs to assist in standing up, the program controls the first electric cylinder 5 to be in a reset state, and the second electric cylinder 6 reaches the maximum stroke. At this time, the massage chair is in the standing state, and the first electric cylinder 5, the seat frame 2 and the base frame 1 form a stable tripod structure, plus the side calf linkage 40 supports the calf support member 4, so that the chassis of the entire massage chair is stable, and at the same time provides stable strength and stable support for the second electric cylinder 6 when working, ensuring the stability of the platform, as shown in FIG. Figure 2 As shown, at this time, the angle between the backrest 22 and the ground at the waist position can reach about 92 degrees, the minimum angle between the arc of the connecting end of the seat 21 and the backrest 22 and the ground can reach about 79 degrees, and the angle between the upper end of the backrest 22 and the ground is about 90 degrees, thereby ensuring that the human body does not fall forward, which is more labor-saving than the tilt angle of the comparison document, thereby more effectively assisting the human body to stand up; when the massage chair is massaging, the second electric cylinder 6 is in the reset state, and the seat frame 2, the guide rail frame 3 and the second electric cylinder 6 form a stable tripod structure, which not only ensures the strength of the platform but also has good stability, which can effectively achieve zero-gravity massage and assist the human body to stand up, the arc guide rail 31 is fixed to both sides of the guide rail frame 3 by welding or bolts, and the arc guide rail 31 can be set to a relative L-shape, thereby preventing the guide member 212 from moving in the arc guide rail 31 to achieve lying down or standing up of the backrest 22 on the seat frame 2, as shown in FIG. Figure 5 As shown, a buffer block 23 is provided at the rear end of the seat 21, a buffer pad 24 for the buffer block 23 to abut is provided on the guide rail frame 3, and an anti-slip tooth 25 is provided on the buffer pad 24. The buffer block 23 abuts on the buffer pad 24, and a vertically arranged mounting rod 11 is fixed on the base frame 1. The top of the mounting rod 11 is provided with a hinge point 12 for the base frame 1 and the guide rail frame 3 to be hinged. Figure 4 and Figure 9 As shown, the horizontal plane where the rear end of the seat 21 is located is level with the horizontal plane where the hinge point 12 is located, which is a lying state or a sitting state, and the buffer block 23 abuts against the buffer pad 24, as shown. Figure 1 and Figure 2 As shown, when the horizontal plane where the rear end of the seat 21 is located is higher than the horizontal plane where the hinge point 12 is located, it is in the standing state, and the buffer block 23 is away from the buffer pad 24.
