[0002] In the prior art, electric massage chairs or massage sofas use electric push rods to drive the seat frame and the backrest frame to swing, thereby realizing a leisure swing function. However, the electric push rod cannot adjust its stroke in real time when working, so that the amplitude of the swing mechanism cannot be adjusted. The swing amplitudes that children, the elderly, pregnant women and normal adults can accept are different. When the amplitude cannot be adjusted, only a compromise can be selected, so it cannot be adjusted according to needs, which has limitations when used. Summary of the invention

[0003] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a double-guide rail rocking leisure chair frame structure with adjustable spacing, which adopts double-arc guide rail frames to form a rocking track for the seat frame to rock, and the spacing between the double-arc guide rail frames can be relatively adjusted, so as to adjust the rocking height while keeping the stroke length of the electric push rod unchanged.

At this time, the cooperation of the first arc guide frame and the second arc guide frame will form a swing track for guiding the seat frame to swing. At this time, when the swinging electric push rod is working, it is equivalent to pushing the seat frame along the swing track, thereby realizing its swing function, and the working stroke of the swinging electric push rod remains unchanged. When the distance between the first arc guide frame and the second arc guide frame becomes smaller, it is equivalent to shortening the length of the swing track. At this time, the swinging electric push rod can push the seat frame to swing to a higher position along the swing track while the stroke of the swinging electric push rod remains unchanged, thereby increasing the swing height, and vice versa. It utilizes the changes in the stroke radius and the circular angle, so that it is suitable for adjusting the swing amplitude, so that the product can perform complex swinging compound movements.

[0018] The present invention discloses a frame structure of a double-guide rail swing leisure chair with adjustable spacing, including a massage chair body 1, wherein the massage chair body 1 includes a base 11 and a seat frame 12 movably arranged on the base 11, and in an implementation case of the present invention, it also includes a first arc-shaped guide rail frame 21 fixedly arranged on the base and a second arc-shaped guide rail frame 22 that can slide back and forth relative to the base 11, the first arc-shaped guide rail frame 21 and the second arc-shaped guide rail frame 22 cooperate to form a swing track 2, two groups of swing tracks 2 are relatively arranged on the base 11, the seat frame 12 is arranged between the two groups of swing tracks 2, and the seat frame 12 is provided with a first guide rail sliding member 3 that guides and slides on the first arc-shaped guide rail frame 21, The seat frame 12 is provided with a second guide rail sliding member 4 for guiding and sliding on the second arc guide rail frame 22. The first arc guide rail frame 21 and the second arc guide rail frame 22 are arranged in sequence along the front and rear directions and are relatively offset left and right. The seat frame 12 is guided and slid on the first arc guide rail frame 21 and the second arc guide rail frame 22 through the cooperation of the first guide rail sliding member 3 and the second guide rail sliding member 4. The base 11 is also provided with an adjusting electric push rod 5 for driving the second arc guide frame 22 to slide forward and backward and a swinging electric push rod 6 for driving the seat frame 12 to move. The swinging electric push rod 6 is most preferably hinged on the base, and its output end is hinged on the seat frame. The specific installation belongs to common knowledge known to technicians in this field.

[0019] By adopting the above technical scheme, the first arc guide frame 21 and the second arc guide frame 22 are staggered front and back and left and right, so that the second arc guide frame 22 can be adjusted front and back relative to the first arc guide frame 21 without being blocked. At this time, the cooperation of the first arc guide frame 21 and the second arc guide frame 22 will form a swing track. At this time, when the swing electric push rod 6 is working, it is equivalent to pushing the seat frame 12 along the swing track, thereby realizing its swing function, and the working stroke of the swing electric push rod 6 remains unchanged. When the distance between the first arc guide frame 21 and the second arc guide frame 22 becomes smaller, it is equivalent to shortening the length of the swing track. At this time, the swing electric push rod 6 can drive the seat frame to move to a higher position while the stroke remains unchanged, thereby increasing the swing height, and vice versa. It utilizes the changes in the stroke radius and the circumferential angle, so that it is suitable for adjusting the swing amplitude, so that the product can perform complex swing compound movements.

[0020] The first arc guide frame 21 and the second arc guide frame 22 are both provided with an arc guide rail 7, the first guide rail slide 3 and the second guide rail slide 4 are partially located in the arc guide rail 7, and the first guide rail slide 3 and the second guide rail slide 4 located in the arc guide rail 7 are both provided with a first support roller 8 to support the seat frame 12 to float relatively and swing relatively, the first support roller 8 can both reduce the friction force and provide a supporting force, so that the seat frame 12 can swing relative to the base 11, and the first guide rail slide 3 and the second guide rail slide 4 can slide along the arc guide rail 7, when the swing electric push rod 6 applies force to the seat frame 12, it can drive the first guide rail slide 3 and the second guide rail slide 4 to move along the arc guide rail 7.

[0021] The base 11 is provided with transverse guide rails 9 at positions corresponding to the second arc-shaped guide rail frames 22. The transverse guide rails 9 are provided with at least two groups along the transverse direction. The second arc-shaped guide rail frames 22 are rotatably provided with second support rollers 10 corresponding to the transverse guide rails 9. The plurality of transverse guide rails 9 can prevent the second arc-shaped guide rail frames 22 from rotating relative to each other, thereby better guiding the second arc-shaped guide rail frames 22 to slide forward and backward. When the second arc-shaped guide rail frames 22 slide forward and backward, not only can the swing amplitude be adjusted, but also the function of lying down in zero space can be realized.

[0022] Both ends of the arc-shaped guide rail 7 are opened to form an assembly opening 20, and an anti-detachment cover 30 is provided on the assembly opening 20 (the anti-detachment cover 30 is most preferably fixed by bolts, or can be fixed by welding, and the anti-detachment cover 30 is most preferably provided with an arc-shaped avoidance surface). The assembly opening 20 can facilitate the first support roller 8 to enter the arc-shaped guide rail 7, thereby simplifying the difficulty of assembly, and blocking it through the anti-detachment cover 30, thereby preventing the first support roller 8 from detaching from the arc-shaped guide rail 7.

[0023] The seat frame 12 is also provided with a walking track 40, on which a walking movement 50 is arranged, and on which a massage arm 60 and a massage driving component 70 for driving the massage arm 60 to massage relative to each other are arranged. The massage function can be achieved through the walking movement 50 during swinging, making its function more comprehensive. The walking movement 50 is most preferably combined with a walking shaft and a walking wheel to walk on the walking track 40, and the walking track 40 is most preferably provided with a rack. The massage driving component 70 can drive the massage arm 60 to perform massage through an eccentric mechanism, which can be kneading, tapping, or massaging. Of course, a heating component can also be provided for heat therapy.

[0024] The second arc-shaped guide rail frame 22 between the two sets of swing rails 2 is connected with a connecting rod 80. One end of the adjusting electric push rod 5 is hinged on the base 11, and the other end is hinged on the connecting rod 80. The stability effect is better during movement, and there will be no adjustment time error.
