[0033] Refer to Figures 1-4 A massage chair with seat vertical pulsation, comprising: base mechanism 1, backrest mechanism 2 and pulsation mechanism, base mechanism 1 includes base 11 and first connecting rod 12, and the bottom end of first connecting rod 12 is rotatably arranged on base 11, backrest mechanism 2 includes backrest 21, first connecting piece 22 and second connecting piece 23, first connecting piece 22 is rotatably connected with the top end of first connecting rod 12, and pulsation mechanism includes fixed support 3, movable support 4 and drive mechanism 5, fixed support 3 is arranged on base 11, movable support 4 is movably arranged above fixed support 3, drive mechanism 5 is used to drive movable support 4 to vertically pulsate, and seat cushion is arranged on movable support 4, second connecting piece 23 is rotatably connected with movable support 4, and first connecting piece 22 and first connecting rod 12 are arranged on the same side of pulsation mechanism, so that, when using, movable support 4 is driven to vertically pulsate by drive mechanism 5, and more abundant use experience is brought to the user sitting on the seat cushion, since backrest 21 is installed on base 11 through first connecting rod 12, drive mechanism 5 does not need to completely bear backrest mechanism 2, the load of drive mechanism 5 is greatly reduced, and then the installation space of drive mechanism 5 is reduced, and too much chair space is not occupied, and one end of backrest 21 is connected with movable support 4, therefore, the part of backrest 21 connected with the seat cushion moves with movable support 4, and more comfortable experience is brought to the user.

[0034] As Figure 4 And Figure 5 As shown in the drawings, the pulsation mechanism further comprises transmission connecting rod mechanism 6, transmission connecting rod mechanism 6 comprises second connecting rod 61 and two third connecting pieces 62, both third connecting pieces 62 are rotatably arranged on fixed support 3, the same end of both third connecting pieces 62 is rotatably connected with second connecting rod 61, and the other end is rotatably connected with movable support 4, so that, through second connecting rod 61, the synchronous movement of both third connecting pieces 62 is ensured, and the stable movement of movable support 4 is ensured, and transmission connecting rod mechanism 6 is preferably provided with two, and the two transmission connecting rod mechanisms 6 are arranged in parallel, and the synchronism of the movement of each part of movable support is further improved.

[0035] As Figure 5 And Figure 6As shown, the driving mechanism 5 includes a rotating shaft 51, two transmission assemblies and a power assembly, the rotating shaft 51 is horizontally arranged on the fixed support 3, the two transmission assemblies include an eccentric wheel 52, an eccentric sleeve 53 and a fourth connecting piece 54, the eccentric wheel 52 is sleeved on the rotating shaft 51, the eccentric sleeve 53 is sleeved on the eccentric wheel 52, one end of the fourth connecting piece 54 is arranged on the fixed support 3, and the other end is rotationally connected with the eccentric sleeve 53; and the power assembly includes a motor 56, a first belt pulley 55, a second belt pulley (not shown in the figure) and a transmission belt (not shown in the figure), the motor 56 is arranged on the fixed support 3, the first belt pulley 55 is sleeved on the rotating shaft 51, the second belt pulley is coaxially arranged on the output end of the motor 56, and the transmission belt is sleeved on the first belt pulley 55 and the second belt pulley, in this way, during use, the motor 56 drives the transmission belt to move, so that the rotating shaft 51 rotates, and then the two eccentric wheels 52 rotate synchronously, so that the two eccentric sleeves 53 swing, and then the bottom height of the fourth connecting piece 54 changes, and then the movable support 4 is driven to vertically move.

[0036] As shown in Figure 2 and Figure 3 , the base 11 is horizontally provided with a sliding rail 13, and the fixed support 3 is slidingly arranged on the sliding rail 13, so that the fixed support 3 can slide horizontally on the base 11, and then the seat part can move in the horizontal direction; in order to drive the fixed support 3 to move horizontally, the first electric push rod 14 is arranged on the base 11, the output end of the first electric push rod 14 is connected with the fixed support 3, and the first electric push rod 14 drives the fixed support 3 to move horizontally.

[0037] As shown in Figures 1-3 , in order to further improve the use experience of the user, the leg support 7 is arranged on the side of the movable support 4 away from the backrest 21, which is used to support the leg and the foot; and the leg support 7 is rotationally arranged on the movable support 4, the second electric push rod 8 is rotationally arranged on the movable support 4, the output end of the second electric push rod 8 is connected with the leg support 7, and the angle of the leg support 7 can be conveniently changed through the second electric push rod 8 to adapt to different needs of the user.

[0038] As shown in Figure 5 and Figure 7 , the buffer structure 9 is arranged between the movable support 4 and the fixed support 3, the buffer structure 9 can be composed of a plurality of rubber buffer columns or springs arranged on the bottom of the movable support 4 or the top of the fixed support 3, of course, the buffer structure 9 can also be composed of components with buffering effect such as springs and rubber buffer columns, and the buffer structure 9 can store energy and reduce vibration during the vertical movement of the movable support 4, so that the seat is more stable during vertical up-down movement.

[0039] In summary: when in use, the movable support 4 is driven to move vertically by the driving mechanism 5, so as to bring a more abundant use experience to the user sitting on the seat cushion. Since the backrest 21 is installed on the base 11 through the first connecting rod 12, the driving mechanism 5 does not need to bear the backrest mechanism 2 completely, so the load of the driving mechanism 5 is greatly reduced. The driving mechanism 5 is arranged inside the movable support 4 and the fixed support 3, so as to further reduce the installation space of the driving mechanism 5, without occupying too much chair space. One end of the backrest 21 is connected with the movable support 4, so that the part of the backrest 21 connected with the seat cushion moves with the movable support 4, so as to bring a more comfortable experience to the user.

[0040] Since one end of the backrest 21 and the leg support 7 is rotatably connected with the movable support 4, when the movable support 4 moves vertically, the backrest 21 and the leg support 7 move synchronously, so as to realize the whole chair movement effect.

[0041] The transmission connecting rod mechanism 6, the movable support 4 and the fixed support 3 form a balanced connecting rod structure. This structure has few joints and is convenient to install, so as to ensure that the movable support 4 always remains horizontal. The structure improves the balance effect of the massage chair movement, effectively improves the convenience and efficiency of installation and use, and reduces the cost of structure installation and use.

[0042] The angle of the leg support 7 can be adjusted independently, so as to meet the multi-angle requirement of the lower leg part of the user.

[0043] The specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
