[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of the present invention generally described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0026] Basic embodiment

[0027] Combine Figures 1 to 9 The massage chair of this embodiment includes a base frame 1, a seat frame 2, a back frame 3, a drive mechanism 4, a seat frame shell P1, and a back frame shell P2. The design of the massage chair aims to achieve support for the user's posture changes through the coordinated work of various components, thereby enhancing the user's massage experience.

[0028] The base frame 1 is the basic structure of the massage chair. It supports the weight of the entire massage chair and provides a movable track for the seat frame 2 and the back frame 3. The base frame 1 is provided with a first guide rail 1A and a second guide rail 1B. The angle a between the first guide rail 1A and the front-to-back direction X is designed to be 0 degrees to 30 degrees, preferably 1 degree, and can also be 5 degrees or 15 degrees. Such a design not only ensures the stability of the seat frame 2 and the back frame 3 in the front-to-back direction, but also facilitates their smooth movement. The second guide rail 1B is tilted backward relative to the first guide rail 1A in the front-to-back direction X. The angle b at which it tilts backward relative to the first guide rail 1A is designed to be 100 degrees to 130 degrees, preferably 110 degrees, and can also be 120 degrees. Such a design allows the back frame 3 to better fit the user's back curve when changing postures, thereby improving the comfort of the massage. For ease of explanation, the X direction in the figure is the front-to-back direction, the Y direction is the left-to-right direction, and the Z direction is the up-down direction.

[0029] The seat frame 2 is the part of the massage chair that supports the user's buttocks. It rolls with the first guide rail 1A via seat frame rollers 2A located on its left and right sides. The design of the seat frame rollers 2A enables the seat frame 2 to move smoothly back and forth along the first guide rail 1A, thereby achieving changes in the massage chair's posture. The seat frame shell P1 is mounted on the seat frame 2. This shell not only provides a comfortable sitting experience for the user but also, through its shape design, guides the user to a correct sitting position, enhancing the massage effect. The seat frame shell P1 can be integrally formed with the seat frame 2, such as through injection molding, to improve the structural stability and durability.

[0030] In addition, a lower limb massage structure (not shown) that can be flipped forward and backward can be installed on the front side of the seat frame 2, and can be flipped by the lower limb drive mechanism on the seat frame 2. This design allows the massage chair to massage not only the user's back and buttocks, but also the user's lower limbs, achieving a full body massage effect.

[0031] The back frame 3 is the part of the massage chair that supports the user's back. It rotates with the seat frame 2, and both can move relative to the base frame 1 to change the user's posture. The back frame 3 has first and second rollers 3A and 3B located on its left and right sides. The first rollers 3A roll in conjunction with the first guide rail 1A, while the second rollers 3B roll in conjunction with the second guide rail 1B. This design allows the back frame 3 to move simultaneously along both the first and second guide rails 1A and 1B during changes in posture, thereby better fitting the user's back curve and enhancing massage comfort.

[0032] The back frame 3 is mounted with a back frame housing P2. This housing not only provides a comfortable backrest for the user but also, through its design, guides the user to a correct sitting position, enhancing the massage effect. The back frame housing P2 can be integrally formed with the back frame 3, such as by injection molding, to improve structural stability and durability.

[0033] The drive mechanism 4 is a key component for achieving posture changes in the massage chair. It is mounted between the base frame 1 and the back frame 3 and is used to drive the back frame 3 relative to the first guide rail 1A and the second guide wheel 1B. In this embodiment, the drive mechanism 4 is a telescopic push rod, one end of which is pivotally connected to the base frame 1 and the other end to the back frame 3. When the drive mechanism 4 is extended or retracted, the back frame 3 moves relative to the first guide rail 1A and the second guide rail 1B, thereby driving the seat frame 2 relative to the first guide rail 1A, achieving posture changes in the massage chair.

[0034] The specific working principle of the above implementation is as follows:

[0035] When the user sits on the massage chair, the seat frame 2 and the back frame 3 support the user's buttocks and back. When the user needs to change posture, the drive mechanism 4 starts to work, pushing the back frame 3 to move relative to the first guide rail 1A and the second guide rail 1B. Since the back frame 3 rotates with the seat frame 2, the movement of the back frame 3 will drive the seat frame 2 to move relative to the first guide rail 1A. Driven by the drive mechanism 4, the massage chair will gradually change from the sitting position to the lying position (refer to Figure 7 ), thus meeting the different massage needs of users.

[0036] In addition to the basic embodiments described above, the present invention may also have a variety of modified embodiments to meet the needs and scenarios of different users.

[0037] Modified embodiment 1

[0038] Based on the first embodiment, this modified embodiment adjusts the coordination between the guide rails and the rollers. Specifically, the first guide rail 1A can be adjusted to slide with the seat frame 2 and back frame 3, and the second guide rail 1B can be adjusted to slide with the back frame 3. In other words, the aforementioned rollers can be adjusted to function as sliders. This design makes the massage chair more stable during posture changes and reduces the noise and vibration that may be generated by the rolling rollers.

[0039] Modified Example 2

[0040] Based on the first embodiment, this modified embodiment partially adjusts the coordination between the guide rails and the slider. Specifically, only the first guide rail 1A can be adjusted to a sliding engagement with the seat frame 2 and back frame 3, while the second guide rail 1B maintains a rolling engagement with the back frame 3. Alternatively, only the second guide rail 1B can be adjusted to a sliding engagement with the back frame 3, while the first guide rail 1A maintains a rolling engagement with the seat frame 2 and back frame 3. This design maintains the smooth rolling of the rollers while increasing the stability of the slider's sliding motion, thereby improving the overall performance of the massage chair.

[0041] Modified embodiment three

[0042] Based on the first embodiment, this variation modifies the drive mechanism 4. Specifically, the drive mechanism 4 can be modified to adopt a slider-type push rod. Compared to telescopic push rods, slider-type push rods offer a more compact structure and higher thrust output, making them suitable for massage chairs requiring greater thrust. This design allows for more powerful massage during posture changes, better meeting the user's massage needs.

[0043] Modified Example 4

[0044] Based on the first embodiment, this variation adjusts the installation position of the drive mechanism 4. Specifically, the drive mechanism 4 can be positioned between the base frame 1 and the seat frame 2, driving the seat frame 2 relative to the first guide rail 1A. When the seat frame 2 moves relative to the first guide rail 1A, it drives the back frame 3 relative to the first and second guide rails 1A, 1B. This design allows for greater flexibility in changing massage positions and enables a wider range of massage methods.

[0045] Modified Example 5

[0046] Building on the first embodiment, this modified embodiment expands upon the additional functions of the massage chair. Specifically, the massage chair can be equipped with additional massage components, such as shoulder massage mechanisms, arm massage mechanisms, and leg massage mechanisms, to provide a full-body massage for the user. These additional massage components can be driven by independent drive mechanisms or in conjunction with the main drive mechanism 4, thereby providing a more comprehensive and personalized massage experience.

[0048] Building on the first embodiment, this variation upgrades the massage chair's control system to a more intelligent one. Specifically, the massage chair can be equipped with an intelligent control system, including touchscreen, remote control, voice control, and other interactive methods. Through the intelligent control system, users can freely set and adjust parameters such as the massage mode, intensity, and duration, achieving a more intelligent and personalized massage experience. Furthermore, the intelligent control system can be connected to the user's smartphone, smart bracelet, and other smart devices, enabling even more convenient and intelligent massage control.

[0049] Modified Example 7

[0050] Building on the first embodiment, this modified embodiment optimizes the materials and appearance of the massage chair. Specifically, the seat frame P1 and back frame P2 can be made of more comfortable and environmentally friendly materials, such as memory foam and eco-friendly leather. Furthermore, the massage chair's appearance can be personalized, with various colors, shapes, and patterns to meet the user's diverse aesthetic needs and specific scenarios.

[0051] Modified Example 8

[0052] Building on the first embodiment, this modified embodiment improves the massage chair's portability and foldability. Specifically, the massage chair can be designed to be foldable, making it easier for the user to store and carry when not in use. Furthermore, the weight and volume of the massage chair can be optimized to reduce the user's burden and improve ease of use.

[0053] In summary, the massage chair of this utility model achieves the functions of supporting the user's posture changes and providing full-body massage through the coordinated operation of components such as the base frame 1, seat frame 2, back frame 3, and drive mechanism 4. Furthermore, this utility model provides a variety of modified embodiments to meet the needs of different users and scenarios.
