Detailed Description

The present application is described in further detail below in conjunction with figures 1-11.

Embodiment one:

referring to fig. 1 and 2, a massage chair includes a base 1, a seat 2, a backrest 3, a lower leg 5, and side plates 4 on both sides of the seat 2. A movement 6 for massage is arranged in the backrest 3. One end of the backrest 3 is hinged with the seat 2, both sides of the seat 2 are provided with a front roller 21 and a rear roller 22, and both sides of the backrest 3 are provided with backrest rollers 31; the lower leg portion 5 is hinged to an end of the seat portion 2 remote from the backrest 3.

Referring to fig. 3, first guide rails 11 for moving the front roller 21 and the rear roller 22 are installed at both sides of the base 1; i.e. the front roller 21 and the rear roller 22 both roll in the first guide rail 11. Second guide rails 12 for the backrest rollers 31 to move are also installed on both sides of the base 1. In this embodiment, the first guide rail 11 is an arc guide rail, and the middle part of the arc guide rail is low and the two ends of the arc guide rail are high; the front roller 21 and the rear roller 22 both roll in the arc-shaped guide rail. The arcuate rail is located below the second rail 12.

Specifically, when the seat 2 moves toward the lower leg portion 5 along the first rail 11, the angle between the seat 2 and the horizontal plane increases. When the backrest 3 moves along the second guide rail 12 toward the lower leg portion 5, the angle between the backrest 3 and the horizontal plane decreases. The base 1 is provided with a first driving piece for driving the seat 2 to move along the first guide rail 11 and driving the backrest 3 to move along the second guide rail 12 through the seat 2. Since the backrest 3 is hinged to the seat 2, when the first driving member moves the seat 2 along the first rail 11 toward the lower leg 5, the backrest 3 also moves along the second rail 12 toward the lower leg 5, and the angle between the backrest 3 and the horizontal plane is reduced.

Referring to fig. 4 and 5, further, hinge shafts 23 are mounted to both sides of the seat 2, and both side plates 4 are hinged to the hinge shafts 23 of both sides of the seat 2, respectively. Drive shafts 32 are provided on both sides of the backrest 3, and drive grooves 41 are provided on the side plates 4. The driving shaft 32 moves in the driving groove 41, so that the backrest 3 drives the side plate 4 to rotate around the hinge shaft 23 through the driving shaft 32. The drive shaft 32 is rotatably mounted with a drive wheel which rolls in the drive groove 41. When the backrest roller 31 moves toward the lower leg portion 5 along the second guide rail 12, the side plate 4 rotates clockwise about the hinge shaft 23, i.e., toward the rear side of the backrest 3, under the action of the driving shaft 32, without moving backward as a whole, i.e., without leaking out of the hinge between the lower leg portion 5 and the seat portion 2, thereby affecting the beauty of the massage chair. So, when back 3 descends the back, the human body lies on the massage armchair with comparatively comfortable gesture, and the arm also can be comfortably placed on the handrail of curb plate 4, and the arm massage can not misplace, promotes user experience and feels.

Referring to fig. 6 and 7, the first driving member includes a first electric putter 7. The first electric push rod 7 adopts a slide block type push rod. The first electric putter 7 is mounted with a drive block 71. A linkage rod 24 is fixedly arranged at the bottom of the seat part 2. One end of the electric push rod, which is close to the lower leg part 5, is hinged with the base 1, and the other end is a free end. The end of the linkage rod 24 remote from the seat 2 is hinged to the drive block 71.

A second driving element and an abutment block 9 are mounted at the bottom of the seat 2. The second driving piece comprises a second electric push rod 8, and the second electric push rod 8 adopts a telescopic push rod. The abutment block 9 includes a first hinge portion 91, a second hinge portion 92, and an abutment portion 93. The lines of the first hinge portion 91, the second hinge portion 92, and the third abutting portion 93 enclose a triangle. The first hinge 91 is hinged to the bottom of the seat 2 on the side near the lower leg 5. The second hinge 92 is hinged to one end of the second electric push rod 8, and the other end of the second electric push rod 8 is hinged to the bottom of the seat 2. The abutment 93 is for abutting the lower leg 5 to rotate the lower leg 5 about the hinge between the seat 2 and the lower leg 5. Wherein, the third abutting part 93 is rotatably provided with an abutting wheel, and the abutting wheel abuts against the shank 5, so that friction can be reduced, and the shank 5 can be conveniently pushed to rotate. The second electric push rod 8 is extended, so that the abutting portion 93 can be driven to rotate around the first hinge portion 91, and the lower leg portion 5 is further driven to rotate.

Further, two auxiliary grooves 42 are formed in the side plate 4 at intervals, auxiliary shafts 25 are mounted on the seat 2 in one-to-one correspondence with the auxiliary grooves 42, auxiliary wheels are rotatably mounted on the auxiliary shafts 25, and each auxiliary wheel rolls in the corresponding auxiliary groove 42. The side plate 4 is more stable during rotation by the cooperation of the auxiliary wheel and the auxiliary groove 42. In other embodiments, one or more auxiliary grooves 42 may be provided and are in one-to-one correspondence with the auxiliary shafts 25.

Referring to fig. 6 and 7; when the massage chair is in the initial state, i.e. the driving block 71 is positioned at the end of the first electric push rod 7 far from the lower leg 5, the angle between the backrest 3 and the seat 2 is D. When the first electric push rod 7 drives the driving block 71 to move towards the lower leg 5, the seat 2 is driven to move towards the lower leg 5 along the first guide rail 11, so that the included angle between the seat 2 and the horizontal plane is increased by D1; at the same time, the backrest 3 is also moved along the second guide rail 12 in the direction of the lower leg 5, so that the angle between the backrest 3 and the horizontal plane is reduced by D2. The angle between the seat 2 and the backrest 3 is D, D and D2. The side plate 4 rotates D3 clockwise around the hinge shaft 23 under the action of the driving wheel. When the driving block 71 moves to the end of the first electric push rod 7 closest to the lower leg part 5, the lower leg part 5 is driven to rotate upwards around the hinge joint by the second electric push rod 8; the human body can lie on the massage armchair, the gravity center is positioned at the hip position and is in a zero gravity state; namely, the massage armchair can cause the sense of weightlessness in outer space.

Embodiment two:

unlike the first embodiment, referring to fig. 8 to 11, the first rail 11 is divided into a front roller rail 13 and a rear roller rail 14. The front roller 21 rolls in the front roller rail 13 and the rear roller 22 rolls in the rear roller rail 14. The front roller rail 13 is located above the rear roller rail 14. The front roller guide rail 13 is of an inclined linear structure and is inclined upward toward the lower leg 5; the rear roller rail 14 is disposed horizontally. The second guide rail 12 is adapted to the moving track of the front roller 21 and the rear roller 22, and has a certain radian, that is, the second guide rail 12 protrudes toward the lower leg 5. The end of the front roller rail 13 remote from the lower leg portion 5 abuts against the end of the second rail 12 near the lower leg portion 5.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
