Description

Technical Field

[0001] This utility model relates to the field of massage chair frame technology, specifically a massage chair frame structure that allows the user to lie flat. Background Technology

[0002] In the modern health industry and home furnishing sector, massage chairs, as devices that can relieve physical fatigue and promote blood circulation, are experiencing a continuous rise in market demand. The iron frame structure of a massage chair, as the core component supporting the entire device, bearing the user's body, and enabling angle adjustment, directly impacts the comfort and suitability of the massage experience.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the iron frame structure of most massage chairs on the market has obvious limitations in terms of angle adjustment, which makes the user's body always in a certain tilt angle when using the massage chair. The waist, back and other parts cannot be fully relaxed, resulting in the force points of the back and buttocks being relatively concentrated. Long-term use can easily cause local pressure and affect the massage effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a massage chair frame structure that can be laid flat, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a reclining massage chair frame structure to solve the problem mentioned in the background art that most massage chair frame structures on the market have significant limitations in angle adjustment.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A reclining massage chair frame structure includes a support mechanism and an adjustment mechanism. The support mechanism includes a base frame, with support frames fixedly installed on both sides of the upper end of the base frame. The adjustment mechanism includes an L-shaped support frame, a seat mounting frame, and a backrest mounting frame. The bottom two sides of the L-shaped support frame are rotatably connected to the upper ends of a pair of support frames, and both sides of the upper end of the L-shaped support frame are equipped with slide rails. One end of the seat mounting frame is rotatably connected to the inner bottom two sides of the L-shaped support frame, and the other end of the seat mounting frame is hinged to connecting members via pins. One end of the backrest mounting frame is hinged to the other ends of a pair of connecting members via pins, and both sides of the other end of the backrest mounting frame are equipped with pulleys that are rollingly connected to the slide rails. A first connecting frame is fixedly installed at the bottom end of the backrest mounting frame, and a second connecting frame is fixedly installed at the bottom end of the L-shaped support frame.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the base frame and support frame of the support mechanism provide stable support for the overall structure. In the adjustment mechanism, the L-shaped support frame, seat mounting frame and backrest mounting frame cooperate through connectors, slide rails and pulleys to realize the linkage adjustment of the angle of the seat and backrest. By adjusting the angle of the L-shaped support frame, the user's posture is initially adjusted. Then, through the linkage adjustment of the seat mounting frame and backrest mounting frame, the user's posture is further adjusted to meet the user's different needs from sitting to lying down. The first connecting frame and the second connecting frame provide connection points for power transmission. The overall structure is rigid and flexible in adjustment, improving the comfort and adaptability of the massage chair.

[0009] Furthermore, a truss is fixedly installed inside the base frame, and a first connecting rod is hinged to one side of the truss via a pin.

[0010] The beneficial effects of adopting the above-mentioned further scheme are that the truss inside the base frame enhances the stability and load-bearing capacity of the support structure, and the first connecting rod, as a transmission medium, provides traction for the adjustment of the seat plate mounting frame and the L-shaped support frame, ensuring that the angle adjustment process is smooth and reliable.

[0011] Furthermore, the other end of the first link is hinged to a second link via a pin, the other end of the second link is hinged to a third link via a pin, and one side of the second link is hinged to one side of the second connecting frame via a pin.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the first link, the second link and the third link form a multi-segment transmission structure, which can be flexibly rotated through the pin hinge. The second link is hinged to the second connecting frame, and works with other links to push the L-shaped support frame to change the angle, thereby improving the linkage accuracy of the adjustment mechanism.

[0013] Furthermore, a fourth link is hinged to the other end of the third link via a pin. The top end of the fourth link is hinged to the bottom side of the L-shaped support frame via a pin, and a roller is installed at the bottom end of the fourth link. The beneficial effect of this further solution is that the hinged connection between the third and fourth links, along with the lifting mechanism between the links, pushes the L-shaped support frame to rotate around the support frame. The roller at the bottom reduces friction between the fourth link and the base frame during movement, ensuring that the adjustment process of the L-shaped support frame is effortless and smooth, and enhancing the fluidity of the mechanism's operation.

[0014] Furthermore, it also includes a lifting mechanism, which includes a pair of reducers, the bottom ends of which are respectively hinged to one side of the upper end of the base frame and the upper end of the first connecting frame via pins.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the reducer of the lifting mechanism is hinged to the base frame and the first connecting frame respectively, which can provide a stable driving force. Through the reduction and torque amplification effect, the lifting amplitude is precisely controlled, providing power support for the angle adjustment of the L-shaped support frame and the back plate mounting frame, ensuring that the adjustment process is controllable and efficient. Furthermore, a lifting frame is installed at the upper end of each reducer, and lifting rods are slidably installed inside each lifting frame. The top ends of a pair of lifting rods are hinged to the bottom side of the L-shaped support frame and the bottom side of the back plate mounting frame respectively via pins.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the sliding groove inside the lifting frame limits the lifting rod's raising and lowering. The lifting rod inside the lifting frame can slide along the axis, and its top end is hinged to the L-shaped support frame and the back plate mounting frame. This can convert the power of the lifting mechanism into the thrust for angle adjustment. By changing the length, the L-shaped support frame is rotated, realizing the angle adjustment of the seat plate mounting frame and the back plate mounting frame, which can meet the needs of users of different body types.

[0017] Furthermore, each of the inner bottom ends of the lifting frame is rotatably connected to a screw rod, and the lifting rod has a threaded groove inside, with the screw rod and the threaded groove being threadedly connected.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the screw and the lifting rod are threaded together, which converts the rotational motion of the screw into the linear lifting motion of the lifting rod.

[0019] Furthermore, a drive motor is fixedly installed on one side of the reducer, the output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the screw drive.

[0020] The beneficial effects of adopting the above-mentioned further solution are that the drive motor provides power to the screw, and after the speed reduction and torque increase by the reducer, it drives the screw to rotate, realizing the automatic lifting of the lifting rod without manual operation. The adjustment efficiency is high and the speed is controllable. The adjustment direction can be flexibly switched by the forward and reverse rotation of the drive motor to meet the rapid conversion between sitting and lying positions.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The iron frame structure of this reclining massage chair provides stable support for the overall structure through the base frame and support frame of the support mechanism. In the adjustment mechanism, the L-shaped support frame, seat mounting frame, and backrest mounting frame cooperate through connectors, slide rails, and pulleys to achieve linkage adjustment of the angle between the seat and backrest. By adjusting the angle of the L-shaped support frame, the user's posture is initially adjusted, and then the user's posture is further adjusted through the linkage adjustment of the seat mounting frame and backrest mounting frame, meeting the user's different needs from sitting to reclining. The first connecting frame and the second connecting frame provide connection points for power transmission. The overall structure is rigid and flexible in adjustment, improving the comfort and adaptability of the massage chair. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-5This utility model provides a technical solution: a reclining massage chair frame structure, including a support mechanism 1 and an adjustment mechanism 2. The support mechanism 1 includes a base frame 101, with support frames 102 fixedly installed on both sides of the upper end of the base frame 101. The adjustment mechanism 2 includes an L-shaped support frame 201, a seat mounting frame 202, and a backrest mounting frame 204. The bottom sides of the L-shaped support frame 201 are rotatably connected to the upper ends of a pair of support frames 102, and slide rails 205 are installed on both sides of the upper end of the L-shaped support frame 201. Both ends of the back plate mounting frame 204 are rotatably connected to the inner bottom ends of the L-shaped support frame 102. Both ends of the other end of the back plate mounting frame 202 are hinged with connecting parts 203 by pins. Both ends of the back plate mounting frame 204 are hinged with the other ends of a pair of connecting parts 203 by pins. Both ends of the other end of the back plate mounting frame 204 are equipped with pulleys 207, which are rolled between the pulleys 207 and the slide rail 205. The bottom end of the back plate mounting frame 204 is fixedly installed with a first connecting frame 206, and the bottom end of the L-shaped support frame 201 is fixedly installed with a second connecting frame 208. As an embodiment of this utility model, a truss 103 is further fixedly installed inside the base frame 101. One side of the truss 103 is hinged to a first connecting rod 104 via a pin. The truss 103 inside the base frame 101 enhances the stability and load-bearing capacity of the support structure. The first connecting rod 104 serves as a transmission medium, providing traction force for the adjustment of the seat plate mounting frame 202 and the L-shaped support frame 201, ensuring a smooth and reliable angle adjustment process.

[0029] As an embodiment of this utility model, the other end of the first connecting rod 104 is hinged to the second connecting rod 105 via a pin, and the other end of the second connecting rod 105 is hinged to the third connecting rod 106 via a pin. One side of the second connecting rod 105 is hinged to one side of the second connecting frame 208 via a pin. The first connecting rod 104, the second connecting rod 105 and the third connecting rod 106 form a multi-segment transmission structure, which can be flexibly rotated by the pin hinge. The second connecting rod 105 is hinged to the second connecting frame 208, and together with other connecting rods, it pushes the L-shaped support frame 201 to change angle, thereby improving the linkage accuracy of the adjustment mechanism 2.

[0030] As an embodiment of this utility model, the other end of the third link 106 is hinged to the fourth link 107 via a pin. The top end of the fourth link 107 is hinged to the bottom side of the L-shaped support frame 201 via a pin. A roller 108 is installed at the bottom end of the fourth link 107. The third link 106 and the fourth link 107 are hinged together. The lifting mechanism 3 is used in conjunction with the links to push the L-shaped support frame 201 to rotate around the support frame 102. The roller 108 at the bottom end reduces the friction between the fourth link 107 and the base frame 101 when the fourth link 107 moves, ensuring that the adjustment process of the L-shaped support frame 201 is effortless and stable, and enhancing the smoothness of the mechanism operation.

[0031] As one embodiment of this utility model, it further includes a lifting mechanism 3, which includes a pair of reducers 301. The bottom ends of the pair of reducers 301 are respectively hinged to one side of the upper end of the base frame 101 and the upper end of the first connecting frame 206 via pins. The reducers 301 of the lifting mechanism 3 are respectively hinged to the base frame 101 and the first connecting frame 206, which can provide stable driving force. The lifting amplitude is precisely controlled by the deceleration and torque increase effect, providing power support for the angle adjustment of the L-shaped support frame 201 and the back plate mounting frame 204, ensuring that the adjustment process is controllable and efficient.

[0032] As an embodiment of this utility model, a lifting frame 302 is further installed on the upper end of the reducer 301. Lifting rods 303 are slidably installed inside the lifting frame 302. The top ends of a pair of lifting rods 303 are respectively hinged to the bottom side of the L-shaped support frame 201 and the bottom side of the back plate mounting frame 204 through pins. The sliding groove provided inside the lifting frame 302 limits the lifting of the lifting rods 303. The lifting rods 303 inside the lifting frame 302 can slide axially. Their top ends are hinged to the L-shaped support frame 201 and the back plate mounting frame 204, which can convert the power of the lifting mechanism 3 into the thrust for angle adjustment. By changing the length, the L-shaped support frame 201 is rotated, realizing the angle adjustment of the seat plate mounting frame 202 and the back plate mounting frame 204, adapting to the needs of users of different body types.

[0033] As an embodiment of this utility model, further, the bottom of the lifting frame 302 is rotatably connected with a screw 305, and the lifting rod 303 has a threaded groove 306 inside. The screw 305 and the threaded groove 306 are threadedly connected, and the screw 305 and the threaded groove 306 of the lifting rod 303 are threadedly engaged, so that the rotational motion of the screw 305 is converted into the linear lifting motion of the lifting rod 303.

[0034] As an embodiment of this utility model, a drive motor 304 is fixedly installed on one side of the reducer 301. The output end of the drive motor 304 is connected to the input end of the reducer 301. The output end of the reducer 301 is connected to the screw 305. The drive motor 304 provides power to the screw 305. After the reducer 301 reduces the speed and increases the torque, it drives the screw 305 to rotate, realizing the automatic lifting of the lifting rod 303. No manual operation is required. The adjustment efficiency is high and the speed is controllable. The adjustment direction can be flexibly switched by the forward and reverse rotation of the drive motor 304 to meet the rapid conversion between sitting and lying positions.

[0035] Specifically, the working principle of this reclining massage chair frame structure is as follows: During use, the base frame 101 and support frame 102 provide stable support, and the truss 103 enhances the overall rigidity; when the posture needs to be adjusted, the drive motor 304 drives the screw 305 inside the lifting frame 302 to rotate via the reducer 301, which in turn drives the lifting rod 303 to rise and fall through the threaded groove 306. One set of lifting rods 303 pushes the L-shaped support frame 201 to rotate around the support frame 102, while the fourth connecting rod 107 moves with the L-shaped support. The frame 201 moves, coordinating with the linkage of the first link 104, the second link 105, and the third link 106, causing the L-shaped support frame 201 to rotate; another set of lifting rods 303 pushes the back panel mounting frame 204, causing it to slide along the slide rail 205 of the L-shaped support frame 201 via pulleys 207. At the same time, the connector 203 links the seat mounting frame 202 and the back panel mounting frame 204, realizing the coordinated adjustment of their angles, and finally completing a smooth transition from sitting to lying down to meet different usage needs.

[0036] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
