Furthermore, some massage chairs cannot simultaneously extend the leg length and increase the support area when lifting the legs, failing to provide a better user experience. Additionally, the backrest adjustment and leg lifting movements of some massage chairs are not flexible or efficient enough, failing to adequately meet diverse user needs. Utility Model Content

[0003] In view of the shortcomings of existing technologies, such as limited leg functions and insufficient flexibility and efficiency in backrest and leg movements, the purpose of this utility model is to provide a multifunctional massage chair frame.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional massage chair frame includes a backrest frame, a backrest guide rail, a backrest push rod, a five-claw base, a leg-raising push rod, a leg-raising linkage assembly, a leg groove, a leg support frame, a first link, a second link, and a third link. The backrest frame is connected to the chair frame body via the backrest guide rail. One end of the backrest push rod is hinged to the chair frame body, and the other end is hinged to the five-claw base. The leg support frame is movably connected to the chair frame body. One end of the leg-raising push rod is hinged to the chair frame body, and the other end is connected to the first link via a connecting rod. The first link is connected to the third link via the second link. The third link is connected to the leg support frame. The leg support frame is connected in the middle, and a leg groove is provided on the side of the leg support frame. The leg groove is connected to one end of the leg-raising linkage assembly, and the other end of the leg-raising linkage assembly is connected to the chair frame body.

[0005] Preferably, the backrest frame slides along the backrest guide rail under the extension and retraction of the backrest push rod, thereby realizing the action of raising or lowering the backrest.

[0006] Preferably, the leg support frame extends forward synchronously during the lifting process to increase the support area for the legs and extend the leg support length.

[0007] Preferably, the leg groove is used to guide the movement trajectory of the leg support frame, ensuring the stability of the leg support frame during lifting and extension.

[0008] Preferably, the second link rotates about its hinge point with the chair frame body to form a lever structure, thereby driving the third link to push the leg support frame forward.

[0009] Preferably, the leg-raising push rod is an electric push rod or a pneumatic push rod, which can remotely control the leg raising and retracting actions.

[0010] Preferably, a sliding guide structure is provided between the backrest frame and the backrest guide rail to prevent the backrest frame from shifting during the lifting and lowering process.

[0011] Preferably, the surface of the leg support frame is provided with an anti-slip structure or a soft padding layer to improve user comfort.

[0012] This invention utilizes the extension and retraction of the backrest push rod to allow the backrest frame to slide on the backrest guide rail, thereby achieving the action of raising the backrest. By extending the leg-raising push rod, the leg-raising linkage assembly is activated, causing the legs to rise. Simultaneously, the first linkage pulls the second linkage, causing the second linkage to perform a lever action, which drives the third linkage to extend the leg support frame, thus achieving the action of raising the legs and extending the leg support frame in conjunction.

[0013] This utility model has the following beneficial effects:

[0014] 1. Multifunctional Experience: The chair frame of this massage chair can elevate the legs while extending the leg length and increasing the support area, providing users with a more comfortable leg support and massage experience, and meeting the diverse needs of users.

[0015] 2. Protective Leather Cover: The design of extending and retracting the leg effectively solves the problem of the leather cover being easily stretched and wrinkled during the leg raising process of existing massage chairs, extending the service life of the massage chair and maintaining its appearance.

[0016] 3. Flexible and efficient: The backrest frame achieves the backrest raising and lowering action by sliding the backrest push rod on the backrest guide rail. The legs are raised and extended in linkage by the leg lifting push rod and linkage assembly. The action is flexible and efficient and easy to operate. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Reference Figure 1-4 The specific embodiment adopts the following technical solution: A multifunctional massage chair frame includes a backrest frame 1, a backrest guide rail 2, a backrest push rod 3, a five-claw base 4, a leg-raising push rod 5, a leg-raising linkage assembly 6, a leg slide groove 7, a leg support frame 8, a first link 9, a second link 10, and a third link 11. The backrest frame 1 is connected to the chair frame body 12 via the backrest guide rail 2. One end of the backrest push rod 3 is hinged to the chair frame body, and the other end is hinged to the five-claw base 4. Through the extension and retraction of the backrest push rod, the backrest frame slides on the backrest guide rail. The leg support frame 8 is movably connected to the chair frame body 12. One end of the leg-lifting push rod 5 is hinged to the chair frame body 12, and the other end is connected to the first connecting rod 9 via a connecting rod. The first connecting rod 9 is connected to the third connecting rod 11 via the second connecting rod 10. The third connecting rod 11 is connected to the leg support frame 8, which is connected in the middle. The side of the leg support frame 8 is provided with a leg slide groove 7, which is connected to one end of the leg-lifting linkage assembly 6. The other end of the leg-lifting linkage assembly 6 is connected to the chair frame body 12. When the leg-lifting push rod is pushed out, the leg-lifting linkage assembly is activated, causing the legs to rise. At the same time, during the leg-lifting process, the first connecting rod 9 pulls the second connecting rod 10, causing the second connecting rod 10 to perform a lever action, which drives the third connecting rod 11 to push out the leg support frame. This achieves the simultaneous extension of the leg support frame as the legs are lifted, increasing the support area for the legs and lengthening the leg length, providing a better user experience.

[0024] The working principle of this specific implementation method is as follows:

[0025] 1. Backrest lifting and backrest movement

[0026] When the backrest angle needs to be adjusted, activate the backrest push rod. The extension and retraction of the backrest push rod causes the backrest frame to slide on the backrest guide rail. When the backrest push rod extends, the backrest frame slides backward, lowering the backrest; when the backrest push rod retracts, the backrest frame slides forward, raising the backrest. Users can adjust the backrest angle to their preferred position.

[0027] 2. Leg lifting and extension movements

[0028] When the legs need to be raised, the leg-raising lever is activated. The leg-raising lever extends, engaging the leg-raising linkage assembly. The movement of the leg-raising linkage assembly causes the leg support frame to rise. Simultaneously, the first link 9 moves with the leg-raising linkage assembly, pulling the second link 10, causing the second link 10 to perform a lever action around its hinge point with the chair frame body. The action of the second link 10 drives the third link 11 to extend, thus causing the leg support frame to extend forward while being raised, increasing the area supporting the legs and lengthening the support length.

[0029] When it is necessary to lower the legs, the leg-lifting push bar retracts, the leg-lifting linkage assembly moves in the opposite direction, the leg support frame descends and retracts, and the coordinated movement of the legs throughout the process effectively avoids the stretching and wrinkling of the sling.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
