Referring to fig. 1 to 8, a massage chair forward movement zero gravity mechanism includes a bottom frame 100 for loading a massage chair main body, a chair frame 200 for bearing a human body, a leg frame 300 for bearing the legs and feet, a link mechanism for transmission, and an electric push rod 20 for driving the chair frame 200 to move forward and turn over, wherein forward movement rollers 80 are rotatably disposed on both sides of the bottom frame 100, forward movement slide rails 201 matched with the forward movement rollers 80 are disposed on both sides of the chair frame 200, the upper end of the leg frame 300 is hinged to the front end of the chair frame 200, the lower end of the electric push rod 20 is hinged to the bottom frame 100, and the upper end of the electric push rod 20 is hinged to the chair frame 200; the link mechanism comprises a lower connecting rod 40, a long connecting rod 30, an upper connecting rod 50 and a leg lifting connecting rod 60, one end of the lower connecting rod 40 is hinged on the underframe 100, and the other end of the lower connecting rod 40 is hinged on the lower end of the long connecting rod 30; the middle of the long link 30 is hinged to the chair frame 200, one end of the upper link 50 is hinged to the upper end of the long link 30, the other end of the upper link 50 is hinged to the rear side of the lower end of the leg raising link 60, the upper end of the leg raising link 60 is hinged to the chair frame 200, the front side of the lower end of the leg raising link 60 is rotatably connected with the leg raising roller 70, and the leg raising roller 70 is in contact with the rear side of the leg and foot rest 300.
In this embodiment, the bottom of the chair frame 200 is fixedly connected with a connecting frame 202, the upper end of the electric push rod 20 and the middle of the long connecting rod 30 are both hinged to the connecting frame 202, the two sides of the bottom frame 100 are both fixedly connected with supporting frames 102, and the forward roller 80 is connected to the supporting frames 102 through a rotating shaft 101.
Preferably, the connecting frame 202 and the supporting frame 102 are both U-shaped frames.
In this embodiment, the forward slide rail 201 is arc-shaped, and the forward slide rail 201 is arc-shaped, which is beneficial to the turning of the chair frame 200.
Preferably, the section of the forward slide rail 201 is U-shaped.
In this embodiment, a leg lifting support plate 301 corresponding to the leg lifting roller 700 is fixedly connected to the rear side of the leg rest 300, and the leg support plate 301 plays a role in reinforcement and support.
In this embodiment, a sponge chair cushion is fixed on the chair frame 200, a chair cover is wrapped on the surface of the sponge chair cushion, a sponge foot pad is fixed on the leg frame, and a leg cover is wrapped on the surface of the sponge foot pad.
The initial state of the massage chair and the leg and foot frame is the standing state, at this time, the electric push rod 20 is in the contraction state, and the forward roller 80 is at the front end of the forward slide rail of the chair frame. When the electric push rod 20 extends, the chair frame 200 slides forward along the forward-moving rollers 80 on both sides of the bottom frame 100 under the driving of the electric push rod 20, and because the forward-moving slide rails on both sides of the chair frame 200 are arc-shaped, the chair frame 200 also tilts while sliding forward. The chair frame 200 slides forward and lies down while driving the long link 30, the leg rest 300, the leg raising link 60, and the leg raising roller 70, which are hinged to the upper front end of the chair frame 200, to move forward and raise upward. The long link 30 moves forward and rises together with the chair frame 200, and simultaneously drives the lower link 40 to turn counterclockwise around the joint of the lower link 40 and the bottom frame 100. One end of the long connecting rod 30 is limited to be turned anticlockwise under the restraining action of the lower connecting rod 40 in the process of moving forwards and lifting, the angle between the long connecting rod 30 and the chair frame 200 is changed, and the hinged end of the long connecting rod 30 and the upper connecting rod 50 rotates downwards. Because the other end of the upper link 50 is hinged to the rear side of the lower end of the leg-raising link 60, the upper end of the leg-raising link 60 is hinged to the chair frame 200, the hinged point of the upper link 50 and the leg-raising link 60 only rotates around the hinged point of the leg-raising link 60 and the chair frame 200, when the hinged end of the upper link 50 and the long link 30 rotates counterclockwise and downward along with the long link 30, the upper link 50 is subjected to a downward and forward acting force of the long link 30, and the acting force is transmitted to the hinged point of the upper link 50 and the leg-raising link 60 along the upper link 50 to drive the leg-raising link 60 to turn clockwise. The leg support 300 is supported by the leg raising roller 70 installed at the front side of the lower end of the leg raising link rod to perform clockwise tilting and lifting operations during the clockwise tilting of the leg raising link rod 60. In combination with the above, during the extension process of the electric push rod 20, the chair frame 200 is driven to move forward, lean and lie, and the leg/foot rest 300 is lifted under the action of the link mechanism, so that the massage chair realizes the functions of forward movement and zero gravity. On the contrary, when the electric push rod 20 is contracted, the chair frame 200 retreats and stands up, the leg rest 300 descends, and the massage chair performs the reset action.
The utility model discloses by single electric putter drive massage armchair antedisplacement and upset, retrencied the mechanical structure and the control system of product, reduced volume and space that occupies to massage armchair's control is simpler, convenient more.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
