Technical Field
[0001] The utility model relates to a foot bath massage chair, in particular to a foot bath seat frame with a three-section flexible guide rail. Background Art
[0002] In recent years, as an important part of health care equipment, the functional innovation of foot bath massage chairs has continuously attracted market attention. The following technical features and limitations generally exist in the current foot bath massage chairs on the market: Refer to Figure 1 As shown, traditional products adopt a double-layer structure of a fixed frame and a movable frame, and realize forward and backward movement through the cooperation of a linear slide rail and an electric push rod drive, which can only meet a certain basic sitting posture adjustment. However, the seat assembly does not have an active massage function at all and is only used as a static support structure.
[0003] In addition, mainstream products integrate a rigid guide rail system inside the backrest frame, and the massage component moves along a preset path through rack transmission to realize back massage. Limited by the structural characteristics of the rigid guide rail, the massage trajectory is usually limited to linear or simple arc movement, and it is difficult to realize flexible massage that conforms to the human spine curve. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a foot bath seat frame with a three-section flexible guide rail, which can enable the guide rail system to achieve flexible adjustment and can massage more conforming to the human curve.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A foot bath seat frame with a three-section flexible guide rail includes a seat guide rail, a back guide rail, a transition guide rail, a massage component, and a driving component. The transition guide rail is located between the seat guide rail and the back guide rail, and both the seat guide rail and the back guide rail are hinged to the transition guide rail; the transition guide rail can be turned up and down relative to the seat guide rail, and the back guide rail can be turned up and down or forward and backward on the transition guide rail; the driving component cooperates with the seat guide rail, the transition guide rail, and the back guide rail to drive the massage component to move so as to massage the seat and the back.
[0007] As a further improvement of the utility model, the position on the transition guide rail for cooperating with the driving component is arc-shaped, and the concave surface of the arc cooperates with the driving component to move, and the seat guide rail and the back guide rail are transitioned through this arc.
[0008] As a further improvement of the utility model, the ends of the transition guide rail corresponding to the seat guide rail and the back guide rail are provided as inclined surfaces, and a space gradually expanding from the concave surface to the convex surface is formed between the transition guide rail and the seat guide rail and the back guide rail through this inclined surface to provide a rotation space between the transition guide rail and the seat guide rail and the back guide rail.
[0009] As a further improvement of the present utility model, an extension portion extending towards the seat guide rail and / or the back guide rail is provided at a position on the transition guide rail for cooperating with the driving assembly, and the transition guide rail shortens the distance from the seat guide rail and / or the back guide rail through this extension portion.
[0010] As a further improvement of the present utility model, the driving assembly includes a connecting frame and a plurality of driving wheels arranged on the connecting frame; the massage assembly is installed on the connecting frame, and the driving wheels cooperate with the seat guide rail, the transition guide rail, and the back guide rail to drive the connecting frame to move; a rack is provided on the transition guide rail, and at least one of the driving wheels is provided with a gear corresponding to the position of the rack. When the driving wheel passes through the transition guide rail, the gear corresponding to the driving wheel meshes with the rack to drive the connecting frame to move.
[0011] As a further improvement of the present utility model, protrusions are provided at positions on the seat guide rail, the back guide rail, and the transition guide rail for cooperating with the driving wheels, and grooves are provided at positions on the driving wheels corresponding to the protrusions, and the grooves and the protrusions form a concave-convex fit.

[0013] As a further improvement of the present utility model, an adjusting assembly is further included, and the adjusting assembly includes an actuator one for adjusting the front-back movement of the seat guide rail and an actuator two for driving the back guide rail to move.
[0014] As a further improvement of the present utility model, the adjusting assembly further includes a mounting frame one for mounting the actuator one and a mounting frame two for mounting the actuator two. The seat guide rail is mounted on the mounting frame two. The actuator one drives the mounting frame two to move to drive the seat guide rail to move back and forth.

Specific embodiments
[0024] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.
[0025] Referring to Figure 2-7 as shown, a foot bath seat frame with a three-section flexible rail in this embodiment includes a seat rail 1, a back rail 2, a transition rail 3, a massage component 4, and a driving component 5. The transition rail 3 is located between the seat rail 1 and the back rail 2, and both the seat rail 1 and the back rail 2 are hinged to the transition rail 3; the transition rail 3 can be turned up and down relative to the seat rail 1, and the back rail 2 can be turned up and down or back and forth on the transition rail 3; the driving component 5 cooperates with the seat rail 1, the transition rail 3, and the back rail 2 to drive the massage component 4 to move, so as to massage the seat and the back.
[0026] When the user adjusts the sitting posture, the transition guide rail 3 drives the seat guide rail 1 and the back guide rail 2 to move together by flipping up and down, and the driving component 5 drives the massage component 4 to move along the hinged path of the three-section guide rail, wherein the transition guide rail 3 allows a more flexible posture adjustment between the back guide rail 2 and the seat guide rail 1, which is more flexible than the traditional posture adjustment scheme with only two guide rails. Due to the flexible adjustment ability of the guide rail, the massage component 4 can adaptively adjust the motion trajectory according to the back curve of the human body, forming a coherent massage path on the seat and back, and improving the massage coverage and comfort. It should be noted that the flexible adjustment refers to the large-range posture adjustment produced by the cooperation of the three-section guide rails, which can better fit the back curve of the human body, so it is called flexible adjustment, rather than referring to the guide rails being made of soft materials. The hinges between the guide rails can be hinged with pins or bolts.
[0027] The driving component 5 in this solution can cooperate with the seat guide rail 1, the transition guide rail 3, and the back guide rail 2 to move, and move the massage component 4 back and forth along the buttocks and back of the human body to massage the entire back and buttocks of the human body, which can solve the defect that the current foot bath chair has no massage function.
[0028] In a preferred solution based on the above solution, the position on the transition guide rail 3 for cooperating with the drive assembly 5 is arc-shaped, and the inner concave surface of the arc cooperates with the movement of the drive assembly 5, and the seat guide rail 1 and the back guide rail 2 transition through the arc.
[0029] When the driving component 5 cooperates along the arc-shaped inner concave surface, the arc-shaped structure provides a smooth curvature for the transition of the guide rail, reducing the friction resistance or transition obstruction during the movement. Through the guidance of the arc surface, the massage component 4 switches between the seat and the back more naturally, avoiding mechanical jamming caused by sharp turns, ensuring the continuity of the massage action, and also allowing the massage component 4 to better fit the curve of the human body for massage, avoiding sudden angle changes that cause discomfort to the human body.
[0030] In order to make the adjustment angle of the transition guide rail 3 larger and further increase the flexibility, the ends of the transition guide rail 3 corresponding to the seat guide rail 1 and the back guide rail 2 are set as inclined surfaces 31, and a space gradually expanding from an inner concave surface to an outer convex surface is formed between the transition guide rail 3 and the seat guide rail 1 and the back guide rail 2 through the inclined surface 31 to provide a rotating space for the transition guide rail 3 and the seat guide rail 1 and the back guide rail 2.
[0031] The design of the inclined surface 31 expands the contact area between the transition guide rail 3 and the seat guide rail 1 and the back guide rail 2. When the guide rails are flipped, the inclined surface 31 provides a greater degree of rotation freedom, allowing the back guide rail 2 to be flexibly adjusted in the up and down or front and back directions to adapt to different user body shapes and avoid massage blind spots caused by limited rotation angles.
[0032] In order to achieve a better transition effect of the drive assembly 5, an extension portion 32 extending toward the seat rail 1 and / or the back rail 2 is provided on the transition rail 3 for cooperating with the drive assembly 5. The transition rail 3 shortens the distance between the seat rail 1 and / or the back rail 2 through the extension portion 32. When the drive assembly 5 drives the massage assembly 4 to move to the vicinity of the extension portion 32, the idle interval is reduced, thereby reducing vibration, ensuring that the massage force is evenly transmitted, and improving the massage accuracy. Moreover, it can cooperate with the inclined surface 31 to provide a better transition effect while meeting a larger driving range. It should be noted that the extension portion 32 needs to meet a certain activity space of the transition rail 3 to avoid the extension portion 32 directly contacting and getting stuck with the seat rail 1 and / or the back rail 2, thereby affecting the rotation of the transition rail 3.
[0033] Based on the optimization of any of the above schemes, the driving component 5 includes a connecting frame 51 and a plurality of driving wheels 52 arranged on the connecting frame 51; the massage component 4 is installed on the connecting frame 51, and the driving wheel 52 cooperates with the seat guide 1, the transition guide 3, and the back guide 2 to drive the connecting frame 51 to move; a rack 33 is provided on the transition guide 3, and at least one of the driving wheels 52 is provided with a gear 53 at a position corresponding to the rack 33. When the driving wheel 52 passes through the transition guide 3, the gear 53 corresponding to the driving wheel 52 engages with the rack 33 to drive the connecting frame 51 to move.
[0034] When the driving wheel 52 moves to the rack 33 area of the transition guide 3, the gear 53 meshes with the rack 33, converting the rotational motion into a linear driving force, pushing the massage component 4 to move precisely along the guide. The coordination between the rack 33 and the gear 53 enhances the transmission efficiency of the driving force, making the movement speed and direction of the massage component 4 controllable, and achieving precise massage point control. In particular, it can cooperate with the arc structure on the transition guide 3, which can make the movement of the driving wheel 52 more stable. The driving wheel 52 can be driven on the seat guide 1, the transition guide 3, and the back guide 2. A rubber anti-slip jacket can be put on the driving wheel 52 to provide better friction. In the arc structure, the coordination between the gear 53 and the rack 33 can make the movement of the arc position smoother and more stable.
[0035] In order to make the driving action more stable, the seat guide rail 1, the back guide rail 2, and the transition guide rail 3 are provided with protrusions 6 at the positions for matching the driving wheel 52, and the driving wheel 52 is provided with grooves 54 at the positions corresponding to the protrusions 6, and the grooves 54 form a concave-convex match with the protrusions 6. The concave-convex match forms a mechanical limit between the driving wheel 52 and the guide rails, making the driving action of the driving wheel 52 more stable and reducing shaking.
[0036] In a further configuration, the tooth tip of the rack 33 is higher than the protrusion 6 , and there is a height difference between the gear 53 and the protrusion 6 .
[0037] The height difference design ensures that the gear 53 only contacts when meshing with the rack 33, reducing interference. When the driving wheel 52 disengages from the area of the rack 33, the gear 53 is suspended, which not only ensures the transmission efficiency but also avoids structural wear.
[0038] To increase the adjustment freedom, an adjustment assembly 7 is further included. The adjustment assembly 7 includes an actuator one 71 for adjusting the front and back movement of the seat rail 1 and an actuator two 72 for driving the back rail 2 to move. This solution can provide the front and back movement adjustment of the seat rail and the movement adjustment of the back rail 2, increasing the free adjustment function.
[0039] In a further setting, the adjustment assembly 7 further includes a mounting bracket one 73 for mounting the actuator one 71 and a mounting bracket two 74 for mounting the actuator two 72. The seat rail 1 is mounted on the mounting bracket two 74. The actuator one 71 drives the mounting bracket two 74 to move, so as to drive the seat rail 1 to move back and forth. The actuator two 72 moves with the movement of the mounting bracket two 74 and drives the back rail 2 to move with this movement action, and the back rail 2 can be driven to move independently.
[0040] The actuator one 71 pushes the seat rail 1 to move back and forth through the mounting bracket two 74 to adjust the user's sitting posture. The actuator two 72 can be linked with the mounting bracket two 74 or independently drive the back rail 2 to achieve multi-level adjustment of the backrest angle and height. The coordinated control of the two enables the seat frame to adapt to users of different heights and provides dynamic support for back massage at the same time. When the actuator two 72 moves with the movement of the mounting bracket two 74 and drives the back rail 2 to move with this movement action, the back rail 2 can form an adaptive effect, and can synchronously and adaptively adjust the back rail 2 when the user adjusts the seat rail 1. After the adaptive adjustment, the back rail 2 can also be adjusted by independently controlling the actuator two 72. It is also possible to adjust the back rail 2 separately through the actuator two 72 before the adjustment of the actuator one 71.
[0041] The actuator in the above solution can adopt components such as an electric push rod, a hydraulic push rod, and a pneumatic push rod.
[0042] The above solution describes a foot bath seat frame. When it is applied to a foot bath massage chair, it includes a foot bath seat frame with a three-section flexible rail according to any one of the above improvement solutions; an armrest 8 that can be turned up and down is also connected to the seat rail 1.
[0043] The mounting bracket one 73 can be mounted on the ground or the seat base. A support surface can be provided on the seat rail 1 for placing a cushion, and a support surface can also be provided on the back rail 2 for placing a backrest. A remote controller can be provided on the armrest 8 for controlling the actuator one 71, the actuator two 72, and the massage assembly 4. The seat rail 1, the back rail 2, and the transition rail 3 mentioned in this solution are not only rails but also bracket-like components with rails.
[0044] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
