Description

Technical Field

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

[0002] With rapid socio-economic development, people's pace of life is constantly accelerating, and work pressure is continuously increasing. Prolonged desk work and lack of exercise have become common lifestyles. This lifestyle easily leads to muscle tension and poor blood circulation, resulting in discomfort symptoms such as neck, shoulder, back, and leg pain, and limb numbness and tingling, seriously affecting people's physical and mental health and quality of life. Against this backdrop, massage chairs, as health devices that conveniently provide home massage, relieve fatigue, and alleviate stress, have become widely available in homes, offices, and leisure spaces, becoming an important choice for people to improve their physical condition.

[0003] Currently, while mainstream massage chairs on the market can achieve basic kneading and percussion massage functions through built-in massage mechanisms, they have obvious shortcomings in terms of human body adaptability and massage experience optimization. On the one hand, the backrest can only achieve fixed angle adjustment, and the reclining angle selection is limited, failing to provide personalized support angles according to different users' body shapes and sitting habits. On the other hand, the design of the zero-gravity mode of existing massage chairs is not perfect. Most of them only achieve it by simply tilting the backrest and leg rest together. It is difficult to truly simulate the natural relaxation posture of the human body in the zero-gravity environment of space. As a result, the body pressure cannot be evenly distributed, and there may still be concentrated pressure on the waist and legs, resulting in poor zero-gravity relief effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a massage chair with a leg support extension, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a massage chair with a leg support extension mechanism, comprising a base, a backrest mechanism, a leg support mechanism, and a drive mechanism; The backrest mechanism can be moved forward and connected to the base; The leg support mechanism is retractably connected to the backrest mechanism; The drive mechanism includes a backrest push rod and a leg support push rod. The backrest push rod is used to drive the backrest mechanism to move forward relative to the base, and the leg support push rod is used to drive the leg support mechanism to extend and retract. The extension and retraction of the leg support mechanism is linked to the forward movement of the backrest mechanism.

[0006] Furthermore, the backrest mechanism is connected to the base via a forward-moving front support frame and a forward-moving rear support frame, together forming a four-bar forward-moving mechanism.

[0007] Furthermore, the leg support mechanism includes an upper leg support frame, a lower leg support frame, a slider, a slide rail, a webbing, and a tension spring; The slide rail is mounted on the iron frame of the leg support, and the slider slides in cooperation with the slide rail; One end of the webbing is connected to the slider, and the other end passes around a fixed shaft and is connected to the lower iron frame of the leg support. The tension spring is connected between the upper iron frame of the leg rest and the lower iron frame of the leg rest.

[0008] Furthermore, the extended end of the leg support push rod is hinged to a foot support lifting mechanism, and the foot support lifting mechanism is connected to the slider; When the leg support push rod is activated, it drives the foot support lifting mechanism to swing, and at the same time drives the slider to move along the slide rail.

[0009] Furthermore, the base is rotatably mounted on a five-star footrest via a lever, allowing the entire massage chair to rotate about the axis of the lever.

[0010] Furthermore, both the backrest push rod and the leg support push rod are electric push rods.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This massage chair with extended leg rests, unlike ordinary massage chairs that can only provide massage at a single angle, allows the chair to rotate and adjust to different angles without affecting the massage effect, improving the convenience of use and optimizing the inconvenience of traditional massage chair seats; compared to single-push-rod massage chairs that cannot be extended, this chair has double push-rods that can be extended and retracted, and the leg rest can move forward with the backrest, enhancing the massage experience, eliminating fatigue, and promoting physical health.

[0012] 2. This massage chair with extendable leg rests has been redesigned from a single SL rail angle adjustment mechanism to a mechanism that allows the backrest and leg rest to move forward together, making the body fit the massage chair better and improving the user experience. The leg rest is now controlled by the same electric push rod as the backrest, reducing the number of push rods compared to other massage chairs. This saves materials, reduces costs, and allows for the extension and retraction of the leg rest while maintaining high cost-effectiveness. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-7 This embodiment of a massage chair with leg support extension addresses the issues of traditional massage chairs having limited backrest angle adjustment and poor zero-gravity mode experience. By using a coordinated design of forward backrest movement and leg support extension, it achieves adjustable support angle and efficient leg support extension, adapting to different users' body shapes and relaxation needs, and improving comfort and soothing effects during the massage process.

[0017] Specifically, the five-star base frame 17 is the fixed support structure of the massage chair. It adopts a stable five-star design to provide reliable support for the overall mechanism and ensure the stability of the massage chair during operation. The base 15 is rotatably mounted on the five-star base frame 17 through the lever 16, so that the entire massage chair can rotate around the axis of the lever 16, making it convenient for users to adjust the orientation of the massage chair to adapt to different usage scenarios.

[0018] Furthermore, a backrest mechanism is connected to the base 15. The backrest mechanism is connected to the base 15 through a forward support frame 10 and a forward support frame 14, forming a four-bar linkage mechanism to enable the backrest mechanism to move forward flexibly relative to the base 15. The backrest mechanism includes a backrest frame 12, which is the core support component of the backrest and can integrate a massage mechanism to achieve massage functions such as kneading and tapping. The drive mechanism includes a backrest push rod 13 and a leg support push rod 11, both of which are electric push rods with stable power output and precise adjustment.

[0019] In actual setup, the four-bar forward movement mechanism consists of a forward-moving front support frame 10 and a forward-moving rear support frame 14, which realizes the forward movement function of the backrest mechanism relative to the base 15. Compared with the traditional fixed backrest, it can better adapt to the user's reclining posture needs and reduce the feeling of the waist being suspended.

[0020] Furthermore, the leg support mechanism is telescopically connected to the backrest mechanism, including an upper leg support frame 8, a lower leg support frame 2, a slider 6, a slide rail 7, a webbing 4, and a tension spring 3; The slide rail 7 is mounted on the upper iron frame 8 of the leg support, and the slider 6 slides in cooperation with the slide rail 7 to provide guidance for the extension and retraction of the leg support. One end of the webbing 4 is connected to the slider 6, and the other end passes around the fixed shaft 5 and is connected to the lower iron frame 2 of the leg support. The fixed shaft 5 forms a fixed pulley structure to change the direction of force transmission. The two ends of the tension spring 3 are connected between the upper iron frame 8 and the lower iron frame 2 of the leg support through the hook 18 to provide elastic force for reset and auxiliary stretching. The extended end of the leg support push rod 11 is hinged to the foot support lifting code 9, and the foot support lifting code 9 is connected to the slider 6 to drive the slider 6 to move along the slide rail 7.

[0021] In actual setup, the sliding cooperation between the slide rail 7 and the slider 6 provides precise guidance for the relative movement of the upper iron frame 8 and the lower iron frame 2 of the leg support, ensuring smooth extension and retraction without deviation; the cooperation between the webbing 4 and the fixed shaft 5 forms a fixed pulley structure, which efficiently transmits the movement of the slider 6 and drives the lower iron frame 2 of the leg support to move synchronously. Compared with gear transmission, the structure is lighter and quieter.

[0022] Working principle: When the massage chair is not started, the backrest 12 is at its initial angle, the forward support frame 10 and the forward rear support frame 14 are in their initial backward position; the leg support mechanism is in its initial retracted state, the upper iron frame 8 and the lower iron frame 2 of the leg support are close to each other, and the tension spring 3 remains in a natural extension and retraction state; the user can adjust the orientation of the massage chair by rotating the base 15 and around the lever 16 to select a comfortable position for use.

[0023] When in use, activate the backrest adjustment function, control the backrest push rod 13 to retract, the backrest push rod 13 drives the backrest frame 12 to adjust the tilt angle, and at the same time, through the transmission of force and motion guidance, drive the forward-moving front support frame 10 and the forward-moving rear support frame 14 to move forward in a circular motion, so that the backrest mechanism moves forward relative to the base 15 to adapt to the user's sitting or reclining posture needs; if it is necessary to return to the initial state, control the backrest push rod 13 to extend, the backrest frame 12 moves upward, the forward-moving front support frame 10 and the forward-moving rear support frame 14 move backward in a circular motion, and the backrest mechanism returns to the initial position.

[0024] When the leg support extension function needs to be activated, the control leg support push rod 11 is extended. The leg support push rod 11 drives the foot support lifting code 9 to move clockwise around the code position fixing axis of the backrest 12, thereby driving the slider 6 to move upward along the slide rail 7. The slider 6 pushes the upper iron frame 8 of the leg support to move clockwise around the fixing axes on both sides of the backrest 12. At the same time, the webbing 4 is shortened due to the upward movement of the slider 6. Under the tension of the tension spring 3, the lower iron frame 2 of the leg support moves downward along the slide rail 7, and the leg support mechanism unfolds into an extended state to meet the user's leg extension needs.

[0025] When the leg rest needs to be retracted, the leg rest push rod 11 retracts, causing the footrest lifting bracket 9 to move counterclockwise around the backrest bracket 12, which in turn causes the slider 6 to move downward along the slide rail 7. The slider 6 pushes the upper iron frame 8 of the leg rest to move counterclockwise around the fixed shafts on both sides of the backrest bracket 12, and the webbing 4 pulls the lower iron frame 2 of the leg rest along the guide rail around the fixed shaft 5. The tension spring 3 gradually returns to its original position, and the leg rest mechanism retracts to its initial state. Users can repeatedly adjust the backrest angle and the extension / retraction state of the leg rest according to their own feelings until the best relaxation effect is achieved.
