[0028] Please refer to Figure 1 and Figure 3 This embodiment provides a massage chair 100, including a chair frame assembly 110 and a support assembly 120. The chair frame assembly 110 includes a guide rail frame 111 and a support fixing member 112 fixedly connected. The guide rail frame 111 is used to install the massage mechanism, and the massage mechanism moves along the guide rail frame 111. The support assembly 120 includes a base 121 and a position fixing plate 122 connected to each other. The base 121 is located on the side of the position fixing plate 122 away from the support fixing member 112. The support fixing member 112 is movably arranged along the length direction a of the position fixing plate 122 and is connected to the position fixing plate 122.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, the massage chair 100 includes a chair frame assembly 110 and a support assembly 120. The chair frame assembly 110 includes a guide rail 111 and a support fixing member 112. The guide rail 111 is mainly used to mount the massage mechanism. The massage mechanism is the core component of the massage chair 100 that enables its massage function, simulating various massage movements of the human hand, such as kneading, pushing, and tapping. The massage mechanism can move along the guide rail 111. Through this design, the massage mechanism can be precisely moved to different parts of the body, such as the neck, back, and waist, thereby achieving comprehensive massage of various parts of the body and meeting the different massage needs of users.
[0030] like Figure 3 As shown, the support assembly 120 includes a base 121 and a position fixing plate 122, wherein the base 121 is located on the side of the position fixing plate 122 opposite to the support fixing member 112. The base 121 serves as the basic support for the entire massage chair 100, providing stable support and ensuring that the massage chair 100 will not shake or tip over during use, thus guaranteeing user safety. The position fixing plate 122, on the other hand, plays a connecting and adjusting role in the overall structure.
[0031] like Figure 1As shown, the support fixing member 112 can move along the length direction a of the position fixing plate 122. Through this movable connection, the relative positional relationship between the chair frame assembly 110 and the support assembly 120 can be flexibly adjusted. Compared with the fixed connection between the base and the chair frame of existing massage chairs, this design of the present application makes the assembly of the massage chair 100 more flexible. No matter how the shape and size of the guide rail frame 111 of the chair frame assembly 110 changes, as long as the position of the support fixing member 112 on the position fixing plate 122 is adjusted, the center of gravity of the massage chair 100 can be kept stable, which greatly improves the adaptability to different chair frame structure styles and reduces production costs.
[0032] It should be noted that, in one possible implementation of this application, firstly, as... Figure 2 As shown, the position fixing plate 122 has a plurality of mounting holes 1221 arranged along the length direction a of the plate, and the support fixing member 112 is assembled with any mounting hole 1221 through the fixing member 150.
[0033] Specifically, such as Figure 2 As shown, the position fixing plate 122 is preferably a long strip plate made of metal or high-strength plastic, and its length direction a is consistent with the front-rear direction of the massage chair 100. The position fixing plate 122 has at least two rows of parallel mounting holes 1221 along its length direction a, and each row of mounting holes 1221 includes multiple spaced mounting holes 1221. The diameter of the mounting holes 1221 and the spacing between adjacent mounting holes 1221 can be adjusted according to actual assembly requirements to meet different adjustment needs.
[0034] The support fastener 112 is used to connect the chair frame assembly 110 and the support assembly 120. Preferably, the support fastener 112 is made of metal or high-strength plastic. A fastener 150 is connected to the side of the support fastener 112 facing the position fixing plate 122. Preferably, the fastener 150 is a bolt or a pin. The support fastener 112 can be inserted into the mounting hole 1221 through the fastener 150 to achieve a fixed connection between the chair frame assembly 110 and the support assembly 120.
[0035] For chair frames with different structural styles, the fore-and-aft position of the support fixing member 112 on the position fixing plate 122 is adjusted by the movable connection between the fixing member 150 and the mounting hole 1221, thereby adjusting the overall center of gravity distribution of the massage chair 100 and ensuring the stability of the massage chair 100. Through this arrangement, the same set of support components 120 can be adapted to various chair frame components 110 with different structures by adjusting the position of the mounting hole 1221, reducing the need for customized bases 121 during production and lowering costs.
[0036] Second, such as Figure 1As shown, the massage chair 100 also includes an electric push rod 130, one end of which is hinged to the guide rail frame 111 and the other end is hinged to the support fixing member 112. Preferably, the electric push rod 130 consists of a motor, a lead screw, and a push rod. The electric push rod 130 drives the lead screw to rotate through the motor, converting the rotational motion into the linear extension and retraction motion of the push rod.
[0037] When the electric push rod 130 extends, the guide rail 111 tilts backward, increasing the backrest angle of the massage chair 100, allowing the user to enter a semi-reclining or fully reclining position. When the electric push rod 130 retracts, the guide rail 111 tilts forward, suitable for scenarios requiring enhanced lumbar massage intensity.
[0038] With precise control of the electric push rod 130, the position of the guide rail 111 can be finely adjusted within a small range, which, in conjunction with the movement of the massage mechanism, enhances the precise massage of specific positions.
[0039] Third, such as Figure 3 As shown, the side of the guide rail frame 111 is provided with a mechanism mounting port 1111. The mechanism mounting port 1111 is a rectangular opening that penetrates the side wall of the guide rail frame 111 to match the shape of the massage mechanism. When installing and removing the mechanism, the massage mechanism can be inserted or pulled out through the mechanism mounting port 1111, avoiding jamming caused by irregular opening shape.
[0040] With the movement mounting port 1111, when installing the movement, the staff can directly place the movement into the appropriate position through the opening on one side of the guide rail 111 without performing complicated internal operations; when maintaining or replacing the movement, the movement can also be easily removed from the side of the guide rail 111 without disassembling a large number of other parts, saving a lot of time and labor costs.
[0041] The massage chair 100 provided in this application includes a chair frame assembly 110 and a support assembly 120. The chair frame assembly 110 includes a guide rail frame 111 and a support fixing member 112 that are fixedly connected. The guide rail frame 111 is used to install the massage mechanism, and the massage mechanism moves along the guide rail frame 111. The support assembly 120 includes a base 121 and a position fixing plate 122 that are connected to each other. The base 121 is located on the side of the position fixing plate 122 away from the support fixing member 112. The support fixing member 112 is movably arranged along the length direction a of the position fixing plate 122 and is connected to the position fixing plate 122. This configuration allows the same support component 120 to be adapted to various chair frame components 110. Compared to the fixed connection between the massage chair base and frame in existing technologies, this application eliminates the need for custom-made bases 121 for each chair frame during production, reducing production costs and improving efficiency. The relative positions of the chair frame component 110 and the support component 120 can be flexibly adjusted. Regardless of the shape or size of the guide rail frame 111 of the chair frame component 110, adjusting the position of the support fixing member 112 on the position fixing plate 122 ensures the stability of the massage chair 100's center of gravity, greatly improving its adaptability to different chair frame structures and meeting diverse production needs. The massage chair 100 exhibits strong stability and assembly adaptability, while reducing production costs and increasing production efficiency.
[0042] For example, such as Figure 2 As shown, to further improve the connection stability between the chair frame assembly 110 and the support assembly 120 and to prevent the support fixing member 112 from shifting relative to the position fixing plate 122, two limiting plates 123 are provided on the side of the position fixing plate 122 facing the support fixing member 112. The two limiting plates 123 extend along the length direction a of the position fixing plate 122 and are located on opposite sides of the position fixing plate 122. When the support fixing member 112 is connected to the position fixing plate 122, the mounting surface of the support fixing member 112 is engaged between the two limiting plates 123. Furthermore, the two limiting plates 123 can also limit and guide the positional movement of the support fixing member 112.
[0043] In one possible implementation of this application, such as Figure 2 As shown, the support fixing member 112 has a rotating shaft 1121 on the side away from the position fixing plate 122, and the electric push rod 130 has a through hole at the end facing the support fixing member 112, and the through hole is sleeved on the outer wall of the rotating shaft 1121.
[0044] Specifically, such as Figure 2As shown, a cylindrical pivot 1121 protrudes from the side of the support fixing member 112 away from the position fixing plate 122. Preferably, the pivot 1121 is made of high-strength metal. The main function of the pivot 1121 is to provide a rotation fulcrum for the electric push rod 130, allowing it to change angle around this point. During the extension and retraction process, the electric push rod 130 forms a hinge relationship with the support fixing member 112, thereby converting linear motion into rotational motion of the guide rail frame 111, realizing the adjustment of the backrest angle of the massage chair 100.
[0045] The bottom end of the electric actuator 130 has a through circular hole, the inner diameter of which is slightly larger than the outer diameter of the rotating shaft 1121 to ensure a clearance fit between them. Preferably, the wall thickness around the through hole is increased or reinforcing ribs are provided to improve the shear strength of this part.
[0046] For example, such as Figure 1 As shown, a connecting shaft 140 is provided on the side of the position fixing plate 122 facing the base 121, and the two opposite ends of the connecting shaft 140 are connected to the position fixing plate 122 and the base 121 respectively.
[0047] Specifically, the connecting shaft 140 is made of metal and has sufficient strength and toughness to withstand various forces generated during the use of the massage chair 100. Preferably, the connecting shaft 140 is cylindrical. This shape ensures connection strength while facilitating assembly with other components, establishing a stable and reliable connection between the position fixing plate 122 and the base 121.
[0048] like Figure 1 As shown, one end of the connecting shaft 140 is connected to the position fixing plate 122. This connection method may be welding, bolting or riveting to ensure that the connecting shaft 140 and the position fixing plate 122 are firmly combined into a whole. The other end of the connecting shaft 140 can be fixedly connected to the base 121 or movably connected. The movable connection allows the chair frame assembly 110 and the support assembly 120 to move relative to each other, further improving the flexibility of the massage chair 100.
[0049] Optionally, one end of the connecting shaft 140 is fixedly connected to the position fixing plate 122, and the other end can be rotatably connected to the base 121 through a bearing, a rotating shaft 1121 assembly or a ball joint, so that the position fixing plate 122 can rotate freely around the axis of the connecting shaft 140.
[0050] Preferably, an arc-shaped groove or a limiting block can also be provided on the base 121 on the rotation path of the connecting shaft 140 to limit the rotation angle of the connecting shaft 140 and the position fixing plate 122, prevent the center of gravity from becoming unbalanced due to excessive rotation, and take into account both flexibility and safety.
[0051] Optionally, the connecting shaft 140 includes a coaxially nested sleeve and a shaft body. One end of the sleeve is fixedly connected to the position fixing plate 122, and the end of the shaft body away from the sleeve is fixedly connected to the base 121. A locking element is provided between the sleeve and the shaft body to fix the relative extension and retraction positions of the sleeve and the shaft body, so as to adjust the distance between the position fixing plate 122 and the base 121.
[0052] Specifically, the sleeve is typically made of high-strength aluminum alloy or steel tubing, with its inner diameter forming a clearance fit with the outer diameter of the inner shaft to ensure that the sleeve can slide freely along the shaft while maintaining coaxiality. The outer wall of the shaft can be coated with a wear-resistant coating to reduce sliding friction.
[0053] It should be noted that a locking element is provided between the sleeve and the shaft. In one specific embodiment of this application, a radial threaded hole is provided on the side wall of the sleeve, and a set bolt is built in. During adjustment, the bolt is loosened, the sleeve is slid to the target position, and then tightened, locking by the friction between the bolt head and the surface of the shaft. In another specific embodiment of this application, multiple positioning holes are provided along the length of the shaft, and elastic pins are provided at corresponding positions on the sleeve. During extension and retraction, the pins slide between the holes, and automatically engage in the holes when reaching the target position. Pressing the pins unlocks the sleeve. Of course, in addition to the above two locking element configurations, other configurations are also possible, and this application does not impose any restrictions on them.
[0054] This configuration allows for adjustment of the overall height of the massage chair 100, accommodating users of different heights and improving the flexibility of its use.
[0055] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
