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. 1-3, an embodiment of the present invention provides a massage chair, which includes a back frame 1, a push rod 2, a seat frame 3, a lower leg assembly 4, a lower leg link 5 and a sleeve assembly;

the seat frame 3 is provided with a sliding chute 6, the bottom end of the back frame 1 is arranged in the sliding chute 6 in a reciprocating sliding manner, the push rod 2 comprises a guide rod 7 and a slide block 8, the slide block 8 is arranged on the guide rod 7 in a reciprocating manner, one end of the guide rod 7 is hinged on the seat frame 3, and the back frame 1 is hinged with the slide block 8;

the lower leg component 4 is hinged with the back frame 1; the sleeve assembly comprises a rotating part 9 and a sliding part 10, the sliding end of the sliding part 10 is connected to the rotating part 9 in a reciprocating sliding manner, one end of the rotating part 9 is hinged with the seat frame 3 at a position far away from the sliding groove 6, the tail end of the sliding part 10 is hinged with the first end of the lower leg connecting rod 5, the second end of the lower leg connecting rod 5 is hinged with the lower leg assembly 4, and the middle part of the sliding part 10 is hinged with the back frame 1;

when the push rod 2 pushes the back frame 1 to slide in the sliding slot 6 along the direction toward the sleeve assembly, the sliding of the back frame 1 drives the sliding member 10 to slide toward the direction away from the rotating member 9, and the sliding member 10 rotates relative to the back frame 1, the rotation will push the shank link 5 to rotate, and the rotation of the shank link 5 drives the shank assembly 4 to rotate relative to the back frame 1.

In particular, as shown in fig. 3, said chute 6 is arranged at the top of the seat frame 1, and one end of the rotating member 9 of the sleeve assembly is hinged at the bottom of the seat frame 3.

It should be noted that, one end of the rotating member 9 is hinged to the seat frame 3, and is not limited to the bottom of the seat frame 3, and the lower leg assembly 4 can be lifted up only if the rotating member 9 is not disposed on the sliding groove 6 but is positioned below the sliding groove 6 to ensure that the rotating member 9 can rotate by a certain angle when rotating, but the rotating member 9 is hinged to the bottom of the seat frame 3 by the farthest distance from the tangential direction of the sliding groove 6, and the rotating angle of the rotating member 9 is also the largest, so that the acting force required to push the lower leg assembly 4 to lift up is smaller, which is a preferable scheme.

In addition, it should be noted that one end of the guiding rod 7 is hinged to the seat frame 3, and specifically, one end of the guiding rod 7 is hinged to the bottom of the seat frame 3, not to the position of the sliding groove at the top of the seat frame 3, so as to ensure that the push rod 2 rotates in the circular arc motion along the direction towards the cannula assembly in the largest proportion, and the back frame 1 can be pushed to slide in the sliding groove 6 with the minimum pushing force.

In specific implementation, when the push rod 2 pushes the back frame 1 to slide in the sliding groove 6 along the direction toward the sleeve assembly, the sliding of the back frame 1 drives the sliding member 10 to slide toward the direction away from the rotating member 9, and the sliding member 10 rotates relative to the back frame 1, the rotation will push the lower leg link 5 to rotate, and the rotation of the lower leg link 5 drives the lower leg assembly 4 to rotate relative to the back frame 1. The massage chair realizes the functions of zero wall leaning, zero gravity and shank linkage only by using one push rod, and has the advantages of low cost, simple structure and easy assembly.

Further, as shown in fig. 3, the number of the sliding grooves 6 on the seat frame 3 is two, and the back frame 1 is disposed on the sliding grooves 6 through two sets of pulleys.

In specific implementation, the bottom of the back frame 1 may be provided with pulleys (not shown in the figure) adapted to the sliding grooves 6, and the pulleys are respectively configured at two sides of the bottom of the back frame 1, so as to slide in the sliding grooves 6.

Further, as shown in fig. 3, the slide groove 6 has a non-circular-arc curved structure in which the height of the seat frame 3 gradually decreases in the direction of extending the push rod 2. The sliding groove 6 is a non-circular arc curve structure with gradually reduced height on the seat frame 3, and can realize that the sliding part 10 slides clockwise towards the direction away from the rotating part 9, so that the sliding part 10 rotates relative to the back frame 1, the rotation pushes the shank connecting rod 5 to rotate, and the rotation of the shank connecting rod 5 drives the shank component 4 to rotate relative to the back frame 1, thereby realizing that the shank component is lifted. Of course, the sliding groove may also be an arc curve structure, a regular arc curve structure, and the technical scheme of linking the back frame and the lower leg can also be implemented, which is not described herein again in the embodiments of the present invention.

As shown in fig. 3, the back frame 1 is an L-shaped structure designed for human sitting posture, and a massage movement is arranged on the back frame and can move up and down along the back frame 1.

Further, in one example, a motor is further included, and the motor drives the sliding block 8 to slide on the guide rod 7.

During specific implementation, the sliding block 8 slides on the guide rod 7 along the direction towards the sleeve assembly, so as to push the back frame 1 to slide in the sliding groove 6, the sliding of the back frame 1 drives the sliding block 10 to slide towards the direction away from the rotating block 9, furthermore, the sliding block 10 rotates relative to the back frame 1, the rotation pushes the shank connecting rod 5 to rotate, and the rotation of the shank connecting rod 5 drives the shank assembly 4 to rotate relative to the back frame 1, so as to realize the lifting of the shank assembly.

Further, as shown in fig. 3, the bottom surface of the middle part of the back frame 1 is provided with a lug 11, the slide block 8 of the push rod 2 is hinged on the lug 11, and the middle part of the slide block 10 is hinged with the front end of the back frame 1 near the lower leg assembly 4.

Specifically, as shown in fig. 3, the middle of the sliding member 10 is provided with a first ear seat 12, and the ear seat 12 is hinged with a second ear seat 13 of the back frame 1 near the front end of the lower leg assembly 4.

In specific implementation, as shown in fig. 1, when the push rod 2 pushes the back frame 1 to slide in the sliding slot 6 along a direction toward the sleeve assembly, the sliding member 10 rotates relative to the back frame 1, specifically, the sliding member 10 rotates clockwise with a center of circle in the middle of the first ear seat 12 as a rotation point, the rotation will push the shank link 5 to rotate, the rotation of the shank link 5 drives the shank assembly 4 to rotate relative to the back frame 1, so as to lift the shank assembly, and the raised state of the shank assembly can be shown in fig. 2. Therefore, the massage chair realizes the functions of zero wall leaning, zero gravity and shank linkage only by using one push rod, and has the advantages of lower cost, simple structure and easy assembly.

Further, in an example, because back of the body frame 1 can slide in spout 5, if control push rod 2 is telescopic motion repeatedly, then can make back of the body frame 1 reciprocating sliding in spout 5, and then realize the rocking chair function, expanded the function of ordinary massage armchair, and can help the dormancy, improve user experience.

That is to say, the embodiment of the invention provides a massage chair, the massage chair pushes a back frame to slide in a seat sliding groove through a push rod, and pushes crus to link by matching with a sleeve assembly, so as to realize crus lifting, and thus the massage chair realizes the functions of zero wall leaning, zero gravity and crus linkage by only using one push rod, and has the advantages of low cost, simple structure and easy assembly.
