[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The folding massage chair according to a preferred embodiment of the present utility model, as Figure 1 shown, and referring to Figures 2 - 6 simultaneously, includes a bed frame 1 distributed continuously in three sections (preferably in two sections, and of course, it can also be in three or more sections according to needs, and no limitation is made thereto). The adjacent bed frames 1 are hinged to each other. A row of liftable massage rollers 2 are arranged on the upper surface of the bed frame 1. A support 3 and a moving unit 4 for driving the support 3 to move along the arrangement direction of the plurality of massage rollers 2 are arranged inside the bed frame 1; a driving arm 30 that fits the surface of the massage roller 2 is arranged at the upper end of the support 3; a swing arm 31 and a yaw motor 32 for driving the swing arm 31 to swing are also arranged on the support 3; one end of the driving arm 30 is longitudinally hinged to the support 3, and the other end is driven to swing by the swing arm 31;

[0025] Applying the folding massage chair of the present application, the yaw motor 32 drives the swing arm 31 to swing, and then drives one end of the driving arm 30 to rotate around the hinge point with the support 3, so as to adjust the jacking height of the massage roller 2. Through this adjustment structure method, stepless adjustment of the massage roller 2 can be realized, providing better comfort during massage, and at the same time providing a hardware basis for expanding more multi-gear mixed massage methods.

[0026] This application adopts a three-section structure (feet, buttocks, back). There is a row of freely rotatable and liftable rollers on the surfaces of the three sections. The three sections are linked by a semi-arc to drive the rollers to rotate and lift for massage. The three sections can freely adjust the sitting, lying, and reclining angles. It uses a single-machine sprocket drive, and a single machine drives the rocker arm's semi-arc to adjust the massage intensity and hitting mode.

[0027] Technical innovation points and technical protection points: The three-section single-machine sprocket drive device, and the rocker arm semi-circular arc strength adjustment and hitting device. This device has a reliable and durable structure, significantly comfortable massage, commonly used and inexpensive materials. It can be made into a large massage bed, a small massage chair, or a medium-sized manual massage table.

[0028] Preferably, the moving unit 4 includes a driving gear 40, a driven gear 41, a transmission chain 42, and a driving motor; the driving gear 40 and the driven gear 41 are connected by the transmission chain 42, and the driving gear 40 is driven to rotate by the driving motor; the transmission chain 42 is connected to the bracket 3 through a connecting member 43; a guide rail for guiding the movement of the bracket 3 is provided on the bed frame 1.

[0029] With the above structural design, the driving motor drives the driving gear 40 to rotate, thereby driving the transmission chain 42 to move, and then driving the bracket 3 to move horizontally along the guide rail through the connecting member 43, so that the driving arm 30 can act on the massage rollers 2 at different positions to achieve the overall massage effect.

[0030] Of course, it can be understood that the above driving structure is not the only implementation method, and existing linear driving mechanisms or components can also be used for replacement. The solutions obtained based on the replacement of existing linear driving mechanisms also fall within the protection scope of this application.

[0031] Preferably, two groups of moving units 4 are provided and act on both ends of the bracket 3 respectively; the moving units 4 are designed on both sides, and the moving units 4 on both sides drive the bracket 3 to move synchronously during operation, which can better ensure the stability of the movement.

[0032] Preferably, the connecting member 43 is fixed on the outer surface of the transmission chain 42; a connecting rod 33 for connecting the connecting member 43 and a waist slot 34 for the longitudinal movement of the connecting rod 33 are provided on the bracket 3.

[0033] With this special design, the purpose is to rely on the cooperation of the connecting rod 33 and the waist slot 34 to match the movement track of the connecting member 43 (when moving with the transmission chain 42, the movement track of the connecting member 43 is circular), so that the driving motor does not need to frequently reverse during driving. This additional feature is possessed by existing massage beds and is also a core invention point of this application.

[0034] Preferably, the bracket 3 includes multiple parallel columns 300 and a plurality of connecting fixing plates 301. Each column 300 is fixedly connected to the plurality of fixing plates 301; an activity hole 302 is provided on the fixing plate 301, and a plurality of activity holes 302 form a waist slot 34; preferably, the yaw motor 32 is fixedly installed on any one of the fixing plates 301 (preferably the middle fixing plate).

[0035] Preferably, three columns 300 are provided and are distributed in a triangular shape. This structure is a relatively reasonable structure with good stability and not too heavy weight; the columns can be made of metal pipes.

[0036] Preferably, the connecting member 43 is L-shaped, with the horizontal side connected to the transmission chain 43 and the vertical side connected to the end of the connecting rod 33; the structure is simple, the connection and installation are convenient, and the cost is low.

[0037] Preferably, adjacent bed frames 1 are hinged to each other through a hinge seat 5; the bed frame 1 is square, and the hinge seat 5 is T-shaped (or a shape similar to the T-shaped, such as a shape obtained by arcuating the edge of the T-shaped); the two ends of the T-shaped of the hinge seat 5 are respectively hinged to the upper part of one side surface of the corresponding bed frame 1, and a positioning portion 100 matching the shape of one side groove of the T-shaped of the hinge seat is provided at the lower part of the side surface of the bed frame 1 where the bed frame 1 is hinged to the hinge seat 5; when the two bed frames 1 are unfolded, the positioning portion 100 will correspondingly enter into one side groove of the T-shaped of the hinge seat 5 for positioning, ensuring sufficient contact surface, good integrity, and convenient storage; it should be noted that according to the actual required unfolding angle, the shape and size of the hinge seat 5 can also be adaptively modified.

[0038] Preferably, the massage roller 2 includes two movable rollers 20 arranged side by side. The two ends of the two movable rollers 20 are connected by a first connecting piece 21, and the two ends of the first connecting piece 21 are respectively longitudinally rotatably connected to the ends of the two movable rollers 20; a second connecting piece 22 is longitudinally rotatably connected to the middle position of the first connecting piece 21, and the end of the second connecting piece 22 away from the connection with the first connecting piece 21 is longitudinally rotatably connected to the bed frame 1; adopting this structure, a double-roller structure is used, which can reduce the number of connection points for connecting a conventional single roller to the bed frame by half. At the same time, due to the design of the first connecting piece and the second connecting piece, both of the two movable rollers 20 can have an upward travel of two sections (about the length of the second connecting piece + 1 / 2 the length of the first connecting piece), increasing the height range that the movable roller can be lifted; after the movable roller 20 is lifted, it can rely on self-resetting, or a return spring can be set to pull it back to its original position.

[0039] Preferably, the driving arm 30 is arc-shaped and the opening of the arc faces downward, and the jacking effect is better.

[0040] It should be understood that those of ordinary skill in the art can make improvements or modifications based on the above description, and all such improvements and modifications shall fall within the protection scope of the appended claims of this utility model.
