Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the embodiment of the invention provides a massage chair, which comprises a back frame 1, a seat frame 2, a push rod 3, a telescopic frame 4, a transmission rod 5 and a lower leg assembly 6;

the back frame 1 is rotatably arranged on the seat frame 2, the expansion bracket 4 is slidably arranged at the bottom of the seat frame 2, one end of the push rod 3 is hinged with the back frame 1, and the other end is hinged with the seat frame 2; one end of the transmission rod 5 is hinged with the back frame 1, and the other end of the transmission rod is connected with the shank component 4; one end of the shank component is hinged with the telescopic frame;

when the push rod 3 pulls the back frame 1 to rotate relative to the seat frame 2 in a direction towards the lower leg assembly 4, the back frame 1 pushes the transmission rod 5 to move, and the transmission rod 5 synchronously pushes the telescopic frame 4 to slide in a direction away from the back frame 1.

In one example, as shown in fig. 1 to 3, when the push rod 3 is contracted, i.e. the back frame 1 is pulled to rotate relative to the seat frame 2 in the direction towards the lower leg assembly 6, i.e. the back frame 1 is enabled to realize back falling through contraction of the push rod 3, at this time, the bottom of the back frame 1 pushes the transmission rod 5 to move towards the lower leg assembly 4, and the movement of the transmission rod 5 synchronously pushes the expansion frame 4 to slide towards the direction of the lower leg assembly 6, so that the seat frame 2 is lengthened, and the lower leg assembly 6 is pushed to lift. Thus, the back-falling seat can support the thigh more and the shank is lifted at the same time, which provides a comfortable massage posture for the masseur.

Further, as shown in fig. 4, a first shank link 7 and a second shank link 8 are further included, one end of the first shank link 7 is hinged to the seat frame 2, the other end of the first shank link 7 is hinged to one end of the second shank link 8, the other end of the second shank link 8 is hinged to the middle of the shank component 6, and the middle of the first shank link 7 is rotatably connected to the middle of the transmission rod 5, so that when the transmission rod 5 moves, the first shank link 7 can rotate relative to the transmission rod 5.

During specific implementation, as the middle part of the first shank connecting rod 7 is rotatably connected with the middle part of the transmission rod 5, when the transmission rod 5 moves, the first shank connecting rod 7 can be driven to rotate anticlockwise by any angle by taking a hinged point with the seat frame 2 as a circle center, so that the shank component 6 is pushed to lift by any angle through the second shank connecting rod 8, different massage requirements of massagers are met, and the adaptability is better.

Further, as shown in fig. 5, the first shank link 7 is provided with a strip-shaped sliding slot 9 at the middle part, the transmission rod 5 is provided with a sliding block 10 at the middle part, and the sliding block 10 is connected in the strip-shaped sliding slot in a reciprocating sliding manner. Specifically, as shown in fig. 4, the transmission rod 5 may include a first transmission rod 11, a second transmission rod 12 and a sliding block 10, wherein one end of the first transmission rod 11 is hinged to the back frame 1, the other end is hinged to the sliding block 10, one end of the second transmission rod 12 is hinged to the sliding block 10, and the other end is connected to the telescopic frame 4.

In specific implementation, as shown in fig. 1 to 4, when the massage chair backs down, the first transmission rod 11 drives the sliding block 10 to slide in the elongated sliding slot 9 in a reciprocating manner under the pushing of the back frame 1, so as to drive the second transmission rod 12 to push the expansion frame 4 to slide, so that the seat is lengthened, and the thigh can be supported more in the back-down posture, so as to improve the comfort level of the masseur during massage.

That is to say, for better cooperation expansion bracket 4 towards keeping away from the direction slip of this back frame 1, set up a rectangular shape spout 9 in first shank connecting rod 7 middle part to make expansion bracket 4 can slide wantonly in the length range of rectangular shape spout 9, thereby make seat length extension in certain extent, in order to adapt to the masseur of different heights.

Further, as shown in fig. 5, the first lower leg link 7 is a V-shaped structure, and the elongated sliding grooves 9 are distributed at the turning position of the first lower leg link 7 and the left and right sections near the turning position.

The strip-shaped sliding groove is arranged at the turning position of the first shank connecting rod and the left and right sections of areas close to the turning position, so that the shank component can be lifted up by better matching with the motion of the transmission rod.

Further, as an executable solution, bushings 15 are fixedly arranged on two sides of the bottom of the seat frame 2, and the expansion bracket 4 is slidably arranged in the bushings 15.

In practical application, when the push rod 3 pulls the back frame 1 to rotate relative to the seat frame 2 along the direction towards the lower leg assembly 6, the back frame 1 pushes the transmission rod 5 to move, so that the expansion frame 4 can slide freely in the bushing 15 within the length range of the elongated sliding groove 9, and the length of the seat part can extend within a certain range to adapt to massagers with different heights.

Further, as shown in fig. 4, the telescopic frame is a U-shaped slide bar, and the U-shaped slide bar is hinged with the lower leg assembly 6.

It should be noted that the telescopic frame 4 may be a sliding rod, a sleeve assembly, a telescopic tube assembly, or other components having the same telescopic function, and the embodiment of the present invention is not limited thereto.

Further, as an executable scheme, the length of the long strip-shaped sliding groove arranged in the middle of the V-shaped connecting rod is matched with the slidable length of the telescopic frame. That is, if the maximum extension length of the telescopic frame is adjusted, the length of the elongated sliding groove is adjusted accordingly, the two lengths are matched with each other, and the extension length of the seat part is adjusted accordingly.

The telescopic frame can slide randomly within the length range of the long strip-shaped sliding groove, so that the length of the seat part can be extended within a certain range to adapt to massagers with different heights.

Further, as shown in fig. 1 to 3, the back frame 1 is a linear structure, a massage machine core 14 is disposed on the back frame 1, and the massage machine core 14 can move up and down along the back frame.

Further, as shown in fig. 6 to 7, the massage chair further comprises a base 16, and the seat frame 2 is disposed on the base 16. Although the base is a circular base, other office chair or electric chair bases, such as a rotatable base with sliding rollers, may be used, and the embodiment of the present invention is not limited thereto.
