Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, specifically a massage chair with a flexible structure. Background Technology

[0002] In today's fast-paced life, people often face high work pressure and lack of exercise, leading to discomfort such as soreness, numbness, and muscle tension. Massage chairs, as convenient tools for relieving stress and improving blood circulation, have gradually become common equipment in homes and offices. Their core function is to precisely target fatigued areas of the body by simulating the pressure and angle of a manual massage, achieving a comfortable and relaxing effect. However, mainstream massage chairs on the market have significant limitations in their structural design, making it difficult to fully meet users' dual needs for comfort and massage effectiveness.

[0003] The primary drawback of existing massage chairs is their non-adjustable seat. Because users vary in height and body shape, a fixed seat angle cannot accommodate diverse body forms. Users may experience issues such as unsupported lower back and uncomfortable leg positioning, reducing comfort and potentially causing uneven pressure on specific areas during the massage, thus exacerbating fatigue. Furthermore, the fixed seat angle cannot be adjusted to suit the user's posture, leading to discomfort during prolonged sitting and diminishing the relaxing effect of the massage chair.

[0004] Secondly, the limited reclining angle of existing massage chairs restricts the precision and comprehensiveness of the massage. Relieving fatigue in different parts of the body requires different lying positions. For example, lower back pain and numbness require moderate back extension, while back muscle tension necessitates adjusting the backrest angle so the massage heads better conform to the back's curve. A single reclining angle cannot accommodate diverse massage needs, making it difficult for the massage heads to fully cover fatigued areas. Some areas may lack sufficient massage intensity or be completely unreachable, affecting the evenness and targeted nature of the massage effect and hindering its effectiveness in relieving symptoms such as body aches, numbness, and muscle tension.

[0016] 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.

[0017] Please see Figure 1-3 This embodiment of a massage chair with a flexible structure achieves synchronous or step-by-step adjustment of the three components through electric push rod drive and linkage mechanism transmission, meeting the massage comfort needs of users of different heights and body types, and is suitable for relaxation use in home, office and other scenarios; Its structure mainly consists of a calf assembly 1, a seat cushion 2, a backrest 3, a hinge 4, a backrest iron frame 5, a seat frame 6, a drive device 7, a seat frame foot pad 8, a seat cushion iron frame 9, a backrest foot pad 10, a connecting rod 11, and a calf lifting bracket 12. All components work together to achieve angle adjustment and flexible massage support.

[0018] Specifically, the seat frame 6 is used to support the weight of the entire massage chair and the user's weight; the upper surface of the seat frame 6 is equipped with seat frame foot pads 8, which are made of rubber and are used to limit the lower limit of the movement of the seat cushion iron frame 9, so as to avoid wear and noise caused by hard contact.

[0019] Furthermore, the backrest frame 5 serves as the mounting carrier for the backrest 3. It is rotatably connected to the seat frame 6 via pins. The backrest 3 is fixed to the backrest 3 with bolts. The backrest 3 is wrapped with breathable sponge and wear-resistant fabric, and has an embedded massage mechanism inside, which can realize back massage. The backrest frame 5 and the seat frame 6 are connected to a drive device 7, which is an electric push rod. Both ends are fixed to the seat frame 6 and the backrest frame 5 via pins, and can extend and retract to drive the backrest frame 5 to rotate around the connection point to adjust the tilt angle.

[0020] Furthermore, the seat cushion frame 9 is connected to the seat frame 6 and the backrest frame 5 via a first hinge mechanism, which is a hinge 4. The hinge 4 is fixed to the seat cushion frame 9 by welding and then connected to the seat frame 6 and the backrest frame 5 by pins, allowing the seat cushion frame 9 to rotate around the hinge 4. The seat cushion 2 is fixed to the upper surface of the seat cushion frame 9 by bolts. The seat cushion 2 is made of high-elasticity sponge and conforms to the curve of the human buttocks. The backrest foot pad 10 is installed on the lower surface of the seat cushion frame 9. The backrest foot pad 10 is made of rubber and works with the seat frame foot pad 8 to limit the range of motion of the seat cushion frame 9 and prevent excessive displacement during adjustment.

[0021] In addition, the calf component 1 is a support component for the user's legs. It is connected to the seat cushion frame 9 through a second hinge mechanism. It is filled with soft sponge and covered with breathable fabric. The linkage mechanism connects the backrest frame 5 and the calf component 1. The linkage mechanism includes a connecting rod 11 and a calf lifting bracket 12. One end of the connecting rod 11 is hinged to the backrest frame 5 and the other end is hinged to the calf lifting bracket 12. The calf lifting bracket 12 is fixed to the calf component 1 and is rotatably mounted on the seat cushion frame 9 through a pin connection to realize the lifting and adjustment of the calf component 1.

[0022] In practical applications, the seat frame 6 is installed on the ground, the backrest frame 5 is in a vertically rearward initial angle, the seat cushion frame 9 is placed horizontally, and the lower leg assembly 1 is in a low initial state. None of the components are under stress, and the linkage mechanism is not triggered. The drive device 7 extends, driving the backrest frame 5 to rotate around its connection point with the seat frame 6. The tilt angle gradually increases. As the backrest frame 5 rotates, it drives the connecting rod 11 to move. The connecting rod 11 pushes the lower leg lifting mechanism 12 to perform a semi-circular reciprocating motion around the seat cushion frame 9. The lower leg assembly 1 rises with the lower leg. The lowering lever 12 rises synchronously, achieving linkage with the backrest iron frame 5. When the connecting rod 11 reaches its dead point, the lower leg lifting lever 12 stops moving, the lower leg assembly 1 stops rising, the electric push rod continues to extend, the backrest iron frame 5 continues to rotate and pushes the backrest foot pad 10. Through the transmission of the hinge 4, the tilt angle of the seat cushion iron frame 9 is adjusted synchronously, so that the seat cushion 2 gradually tilts backward to adapt to the human lying posture. After adjusting to the target angle, the electric push rod stops extending, the massage chair maintains the current posture, and the user can start the massage function to relax.

[0023] When the initial state needs to be restored, the electric push rod is activated to retract, and the backrest frame 5 rotates in the opposite direction around the connection point. Through the hinge 4, the seat cushion frame 9 adjusts its angle synchronously and gradually approaches horizontality. When the electric push rod retracts to the dead point of the connecting rod 11, the seat cushion frame 9 stops moving and lands smoothly on the seat frame foot pad 8. The electric push rod continues to retract, and through the transmission of force and motion guidance, the connecting rod 11 pulls the lower leg lifting mechanism 12 down, and the lower leg assembly 1 moves down accordingly. When the electric push rod retraction is complete, the backrest frame 5, the seat cushion frame 9, and the lower leg assembly 1 all return to their initial state, ready for the next use.
