Description

Technical Field

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

[0002] As people's living standards continue to improve and their health awareness increases, massage chairs, as a type of health appliance that can effectively relieve physical fatigue, promote blood circulation, and relax the mind and body, are gradually entering thousands of households and becoming a popular leisure and health care device in modern homes and offices.

[0003] Massage chairs are designed to mimic the techniques of professional massage therapists, using mechanical devices to massage various parts of the body to relieve muscle tension and improve bodily functions. To meet the diverse needs of different users regarding massage posture and comfort, the angle adjustment function of massage chairs is particularly important. During a massage, users often want to be able to freely adjust the chair frame and seat angle according to their physical condition, the areas being massaged, and personal preferences to obtain a massage experience that better suits their needs. For example, when a user wants a full-body relaxation massage, they might prefer to adjust the chair frame and seat to a gentler angle, placing their body in a semi-reclined position to reduce pressure; while when a user needs to focus on massaging specific areas, they may need to adjust the chair frame and seat to a specific angle to better expose the massaged area and enhance the massage effect.

[0004] Existing massage chair angle adjustment technology mainly consists of two parts: chair frame angle adjustment and seat frame angle adjustment. Most existing angle coordination adjustment technologies focus on using hinge points to achieve linkage between the chair frame and seat frame angles. While this achieves some degree of coordinated adjustment between the chair frame and seat frame angles, the position and movement trajectory of the hinge points are relatively fixed during angle adjustment, significantly limiting the adjustment range and methods. Furthermore, when using hinge point linkage to achieve coordinated adjustment of the chair frame and seat frame angles, the mechanical clearance and friction between the hinge points can easily lead to low accuracy in angle adjustment. Utility Model Content

[0005] To solve the above technical problems, this utility model provides a massage chair with coordinated angle adjustment. By connecting the linkage part of the seat frame to the base via a linkage rod, the two ends of the linkage rod are respectively hinged to the linkage part of the seat frame and the base. During the sliding of the chair frame, the linkage rod can drive the seat frame angle to change in a coordinated manner with a unique movement.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An angle-adjustable massage chair includes a base, a chair frame that slides on the base, and a seat frame that is movably hinged to the chair frame;

[0008] The base has a slide rail mechanism adapted to provide a moving path for the chair frame to adjust the angle of the chair frame, and a chair frame drive mechanism for driving the chair frame to slide is disposed between the base and the chair frame.

[0009] The seat frame has a hinged part and a linkage part arranged at intervals. The hinged part is movably hinged to the chair frame, and the linkage part is movably connected to the base via a linkage rod. The first end of the linkage rod is movably hinged to the linkage part, and the second end is movably hinged to the base, so as to coordinately change the angle of the seat frame during the sliding of the chair frame.

[0010] Furthermore, the first end of the linkage is configured to rotate about the second end to change the angle of the seat.

[0011] Furthermore, the slide rail mechanism includes a first slide rail and a second slide rail, wherein the second slide rail is inclined relative to the first slide rail in the front-back direction of the massage chair.

[0012] Furthermore, the first slide rail is inclined upward in the front-to-back direction of the massage chair, and the second slide rail is inclined downward in the front-to-back direction of the massage chair.

[0013] Furthermore, the lengths of the first and second slide rails are configured such that the chair frame does not disengage from the first and second slide rails when the drive mechanism drives the chair frame.

[0014] Furthermore, the slide rail mechanism includes a zigzag-shaped third slide rail, which includes a first guide portion and a second guide portion, wherein the second guide portion is inclined relative to the first guide portion in the front-back direction of the massage chair.

[0015] Furthermore, the first guide portion is inclined upward in the front-back direction of the massage chair, and the second guide portion is inclined downward in the front-back direction of the massage chair.

[0016] Furthermore, the chair frame is engaged with the slide rail mechanism by means of a first chair frame roller and a second chair frame roller located on the left and right sides.

[0017] Furthermore, the drive mechanism includes a telescopic push rod, one end of which is hinged to the base and the other end of which is hinged to the chair frame.

[0018] Furthermore, a seat frame housing is installed on the seat frame, and a chair frame housing is installed on the chair frame.

[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0020] 1. The introduction of the linkage rod in this utility model establishes a close and intelligent collaborative adjustment mechanism between the chair frame and the seat frame. When the chair frame slides along the base's slide rail mechanism to adjust its angle under the action of the chair frame drive mechanism, the linkage rod responds synchronously to this action. Since the two ends of the linkage rod are respectively hinged to the linkage part of the seat frame and the base, when the chair frame angle changes, the linkage rod automatically and precisely drives the linkage part of the seat frame according to its movement trajectory and the relative position of the hinge point, thereby causing the seat frame angle to change collaboratively. This collaborative adjustment method ensures that the chair frame and seat frame angles are always in an optimal matching state, perfectly conforming to the physiological curves of the human body in different massage postures.

[0021] 2. The massage chair of this utility model has a frame that slides or slides with both the first and second guide rails of the base. This distributes the force exerted by the user on the backrest across the first and second guide rails, which helps extend the lifespan of the massage chair. By optimizing the connection between the guide rails and casters, adding additional massage components, and using comfortable materials, the comfort of the massage chair is improved, allowing users to experience greater comfort and relaxation during use.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0034] Please see Figures 1 to 5This utility model relates to a massage chair with coordinated angle adjustment, aiming to provide users with a more comfortable and personalized massage experience. The massage chair mainly includes a base 100, a chair frame 200, and a seat frame 300. Through a unique structural design, the angles of the chair frame and seat frame can be adjusted in a coordinated manner. The base 100 is the basic structure of the massage chair, supporting the weight of the entire chair and providing a track for the chair frame 200 and seat frame 300. A slide rail mechanism 110 and a chair frame drive mechanism 400 installed on the base 100 provide a path and power for the movement of the chair frame 200. The seat frame 300 cooperates with the base 100 and chair frame 200 through a hinge 310, a linkage 320, and a linkage rod 500. In this embodiment, during the sliding of the chair frame 200, the angle of the seat frame 300 can be adjusted in a coordinated manner, so that the adjustable range of the chair frame 200 and seat frame 300 reaches 115-140 degrees, meeting the diverse needs of users. The seat frame 300 has a hinge portion 310 and a linkage portion 320 arranged at intervals. The hinge portion 310 is movably hinged to the chair frame 200, allowing the seat frame 300 to rotate at a certain angle relative to the chair frame 200. The linkage portion 320 is movably connected to the base 100 via a linkage rod 500, with the first end 510 of the linkage rod 500 movably hinged to the linkage portion 320 and the second end 520 movably hinged to the base 100. When the chair frame 200 slides on the slide rail mechanism 110, the first end 510 of the linkage rod 500 rotates around the second end 520, thereby changing the angle of the seat frame 300. For example, when the chair frame 200 slides forward and downward, the linkage rod 500 will rotate as the chair frame 200 moves, causing the seat frame 300 to tilt forward; when the chair frame 200 moves backward and upward, the seat frame 300 will tilt backward, realizing the coordinated adjustment of the angles of the chair frame 200 and the seat frame 300. The specific structure, connection method, working principle and different embodiments of each component will be described in detail below.

[0035] The chair frame 200 is the part of the massage chair used to support the user's back. It rotates and engages with the seat frame 300, and both can move relative to the base 100 to change the user's posture. The chair frame 200 has first chair frame casters 210 and second chair frame casters 220 located on the left and right sides. The first chair frame casters 210 and second chair frame casters 220 slide in engagement with the slide rail mechanism 110. This design allows the chair frame 200 to move along the slide rail mechanism 110 while changing posture, thus better conforming to the user's back curve and improving massage comfort. A chair frame shell 211 is installed on the chair frame 200. The chair frame shell 211 not only protects the internal structure but also enhances the overall aesthetics of the massage chair. The chair frame shell 211 can be made of materials such as plastic or metal, and its surface can be treated with various finishes, such as painting or frosting, to meet different appearance design requirements.

[0036] The seat frame 300 is the part of the massage chair used to support the user's buttocks. A seat frame housing 311 is installed on the seat frame. The seat frame housing 311 not only provides a comfortable seating experience but also guides the user to maintain a correct sitting posture through its shape design, improving the massage effect. In this embodiment, the seat frame housing 311 can be integrally molded with the seat frame 300, such as through injection molding, to improve structural stability and durability. The seat frame housing 311 also serves to protect the internal structure and enhance the aesthetics. The design of the seat frame housing 311 can match the chair frame housing 211, forming a unified appearance. Furthermore, the seat frame housing 311 can be designed according to actual needs, such as by installing massage heads, control buttons, and other components, improving the functionality and ease of use of the massage chair. In addition, a lower limb massage structure (not shown) that can flip forward and backward can be installed on the front side of the seat frame 300, driven by a lower limb drive mechanism on the seat frame. 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.

[0037] Please see Figure 7 In one embodiment, the slide rail mechanism 110 of this application includes a first slide rail 111 and a second slide rail 112. The first slide rail 111 is inclined downward in the front-back direction of the massage chair; specifically, the first slide rail 111 is inclined downward from back to front on the massage chair. The second slide rail 112 is inclined upward in the front-back direction of the massage chair; specifically, the second slide rail 112 is inclined upward from back to front on the massage chair. In this embodiment, the second slide rail 112 is inclined relative to the first slide rail 111 in the front-back direction of the massage chair. The lengths of the first slide rail 111 and the second slide rail 112 are precisely designed to ensure that the chair frame 200 will not disengage from the first slide rail 111 and the second slide rail 112 when the chair frame drive mechanism 400 drives the chair frame 200. This dual slide rail structure provides stable guidance for the movement of the chair frame 200 and enables the chair frame 200 to change angles during movement. For example, when the chair frame 200 slides forward and downward along the first slide rail 111, the angle of the chair frame 200 will gradually change as it is about to transition to the second slide rail 112 due to the different tilt direction of the second slide rail 112.

[0038] Please see Figure 8 , Figure 9In another embodiment, the slide rail mechanism 110 of this application includes a zigzag-shaped third slide rail 113. The third slide rail 113 includes a first guide portion 1131 and a second guide portion 1132 inclined in the front-back direction of the massage chair. The first guide portion 1131 is inclined downwards from back to front on the massage chair, and the second guide portion 1132 is inclined upwards from back to front on the massage chair, with the second guide portion 1132 inclined relative to the first guide portion 1131 in the front-back direction of the massage chair. This zigzag-shaped slide rail design also enables stable movement and angle adjustment of the chair frame 200. Its principle is similar to that of the double slide rail structure, both guiding the chair frame 200 to change angle through tracks with different inclination directions.

[0039] The chair frame drive mechanism 400 is used to drive the chair frame 200 to slide on the slide rail mechanism 110. In this embodiment, the chair frame drive mechanism 400 includes a telescopic push rod 410, one end of which is hinged to the base 100 and the other end to the chair frame 200. When the telescopic push rod 410 extends or retracts, it pushes the chair frame 200 to move forward / backward along the slide rail mechanism 110. For example, when the telescopic push rod 410 extends, it pushes the chair frame 200 to move along the slide rail mechanism 110 to change its support angle to adapt to the reclining position of the human body; when the telescopic push rod 410 retracts, the chair frame 200 moves along the slide rail mechanism 110 to change its support angle to adapt to the sitting or reclining position of the human body. By controlling the extension and retraction length of the telescopic push rod 410, the support angle of the chair frame 200 can be precisely controlled. The chair frame 200 slides in cooperation with the slide rail mechanism 110 through the first chair frame pulley 210 and the second chair frame pulley 220 located on the left and right sides. Whether it's the first slide rail 111 and the second slide rail 112 with a double slide rail structure, or the zigzag-shaped third slide rail 113, the first chair frame pulley 210 and the second chair frame pulley 220 can slide on the corresponding slide rails, reducing friction and making the movement of the chair frame 200 smoother. For example, when the chair frame 200 moves along the first slide rail 111 or the second guide portion 1131, the first chair frame pulley 210 and the second chair frame pulley 220 on the left and right sides will slide on the first slide rail 111 to ensure the smooth movement of the chair frame 200; when transitioning to the second slide rail 112 or the second guide portion 1132, the pulleys can still adapt to different tilt angles and continue to maintain stable sliding.

[0040] Please see Figure 6When the user needs to adjust the angle of the massage chair, the telescopic push rod 410 in the chair frame drive mechanism 400 is activated. The telescopic push rod 410 begins to extend and retract, pushing the chair frame 200 to move along the slide rail mechanism 110. Taking a double slide rail structure as an example, when the telescopic push rod 410 is extended, the support posture of the massage chair can be adjusted to a reclining position. With the cooperation of the first chair frame pulleys 210 on the left and right sides, the chair frame 200 slides forward and downward along the first slide rail 111, while the second chair frame pulleys 220 slide forward and upward along the second slide rail 112. During the sliding of the chair frame 200, since the first end 510 of the linkage rod 500 is hinged to the linkage part 320 of the seat frame 300 and the second end 520 is hinged to the base 100, the movement of the chair frame 200 will cause the linkage rod 500 to rotate. The first end 510 of the linkage rod 500 rotates around the second end 520, thereby tilting the angle of the seat frame 300 forward. At the same time, the linkage 500 continues to drive the seat frame 300 to adjust its angle, realizing the coordinated change of the angles of the chair frame 200 and the seat frame 300.

[0041] When the telescopic push rod 410 is shortened, the chair frame 200 moves along the slide rail mechanism 110 to the rear and upper part of the first slide rail 111 and the rear and lower part of the second slide rail 112. The linkage rod 500 moves in the opposite direction, causing the seat frame 300 to tilt backward, thus achieving coordinated adjustment of the angles of the chair frame 200 and the seat frame 300. For the zigzag third slide rail structure, the working principle is similar, except that the angle change process is smoother and more continuous when the chair frame 200 moves along the zigzag track.

[0042] Throughout the adjustment process, the adjustable angles of the chair frame 200 and seat frame 300 range from 115 to 140 degrees. Users can adjust the massage chair to a suitable angle by controlling the extension and retraction of the telescopic push rod 410 to achieve the best massage experience. For example, when a user wants to relax, the chair frame 200 and seat frame 300 can be adjusted to a larger tilt angle, allowing the body to be in a comfortable semi-reclined position; when a user needs massage therapy, the angle can be adjusted to a more suitable position so that the massage heads can better target various parts of the body.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
