[0002] The prior art relaxation chair has no active up and down rocking function, and no optional function to adjust the rocking frequency and amplitude. The arc bottom leisure chair needs manual force to produce rocking, which cannot achieve the effect of deep relaxation. Summary of the invention

[0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a frequency modulation and amplitude modulation relaxation chair, which is developed in view of the lack of active rocking function in the relaxation chairs in the prior art. The structure is simple and reasonable, so that the relaxation chair can produce active up and down reciprocating rocking, avoiding the situation where a person lying on the relaxation chair needs to actively apply force to rock up and down.

[0004] The present invention is specifically implemented through the following technical solutions:

[0005] The frequency modulation and amplitude modulation relaxation chair of the present invention comprises a supporting part and a shaking part which are connected to each other, wherein the shaking part is located above the supporting part, and a traction mechanism for driving the shaking part to shake up and down is arranged between the supporting part and the shaking part, and the traction mechanism is connected to a motor. A control device connected to the motor is also arranged on the relaxation chair, and when the control device controls the motor to start or stop, the shaking part shakes back and forth around the connection between it and the supporting part in the direction of its force.

[0006] Optionally, the relaxation chair is a structural member formed by integrally molding the support part and the rocking part, and an arc-shaped transition is provided between the support part and the rocking part. The traction mechanism includes a traction rope, a tension spring and a traction wheel. The motor is fixedly arranged on the back side of the rocking part, and the traction wheel is arranged on the output shaft of the motor. The upper end of the traction rope is connected to the traction wheel, and the lower end of the traction rope is connected to the support part via the tension spring.

[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1~Figure 2As shown, this embodiment provides a frequency modulation and amplitude modulation relaxation chair, including a support part 1 located at the bottom and a shaking part 2 located at the top. In this embodiment, the relaxation chair is formed by the support part 1 and the shaking part 2 being integrally formed. The arc transition between the support part 1 and the shaking part 2 makes the relaxation chair R-shaped. A traction mechanism for driving the shaking part 2 to shake up and down is arranged between the support part 1 and the shaking part 2. The traction mechanism is connected to a motor 3. A control device 4 connected to the motor 3 is also arranged on the relaxation chair. When the control device 4 controls the motor 3 to work or stop, the shaking part 2 shakes back and forth around the connection between it and the support part 1 in the direction of its force.

[0031] When the FM / AM relaxation chair of this embodiment is put into practical use, the control device 4 controls the motor 3 to work and stop, that is, the output shaft of the motor 3 rotates to activate the traction mechanism, and the traction mechanism pulls the shaking part 2 downward to cause the R-shaped recliner to elastically deform, thereby realizing the downward movement of the shaking part 2; the output shaft of the motor 3 stops rotating, and the traction force of the traction mechanism on the shaking part 2 is cancelled, and the R-shaped relaxation chair recovers its deformation under the action of its own elastic force, and the shaking part 2 moves upward; in this way, the motor 3 is controlled to work and stop intermittently, and the traction mechanism is driven to cause the shaking part 2 to rock back and forth up and down, so that the human body has a comfortable rocking feeling when resting on the recliner, thereby achieving the purpose of deep relaxation of the body and mind.

[0032] In this embodiment, the control device 4 controls the working time and stopping time of the motor 3, thereby controlling the frequency and amplitude of the up and down shaking of the shaking part 2. The control device 4 can be adaptively selected in the controller or control switch of the existing technology, as long as it can control the working and stopping of the motor 3. As a conventional choice, a time relay, a PLC controller or a single-chip microcomputer controller can be used.

[0033] When a time relay is used to control the operation and stop of the motor 3, the time relay can be a YYC-2S type time relay. When the speed of the motor 3 is constant, the time controller can change the operation time and stop time of the motor 3 to adjust the frequency and amplitude of the shaking part 2.

[0034] When a PLC controller or a single-chip microcomputer controller is used to control the operation and stop of the motor 3, the frequency and amplitude of the up and down shaking of the shaking part 2 can be adjusted by adjusting the operation time, stop time and rotation speed of the motor 3.

[0035] Specifically, in this embodiment, the traction mechanism includes a traction rope 5, a tension spring 6 and a traction wheel 7, the motor 3 is fixedly arranged on the back side of the shaking part 2, the traction wheel 7 is arranged on the output shaft of the motor 3, the upper end of the traction rope 5 is connected to the traction wheel 7, and the lower end of the traction rope 5 is connected to the support part 1 through the tension spring 6.

[0036] In this embodiment, the motor 3 is a permanent magnet DC motor. As a preferred choice, the motor 3 is a permanent magnet DC brushless motor, which has the advantages of high efficiency, low energy consumption, low noise, long service life, high reliability and servo control.

[0037] Embodiment 2:

[0038] This embodiment is a variation of the above-mentioned embodiment 1. To better implement the present invention, the following structure is particularly adopted:

[0039] like Figure 3~Figure 4 As shown, in this embodiment, the support part 1 is rotatably connected to the shaking part 2, an elastic reset structure is arranged between the support part 1 and the shaking part 2, the traction mechanism includes a traction rope 5, a tension spring 6 and a traction wheel 7, the motor 3 is fixedly arranged on the back side of the shaking part 2, the traction wheel 7 is arranged on the output shaft of the motor 3, the upper end of the traction rope 5 is connected to the traction wheel 7, and the lower end of the traction rope 5 is connected to the support part 1 through the tension spring 6.

[0040] In this embodiment, the elastic reset mechanism is a shock absorbing spring 11, the lower end of the shock absorbing spring 11 is against the support part 1, and the upper end of the shock absorbing spring 11 is against the shaking part 2. When the output shaft of the motor 3 rotates, the traction mechanism pulls the shaking part 2 downward to make the shaking part 2 rotate downward relative to the support part 1, and compresses the shock absorbing spring 11 at the same time; when the output shaft of the motor 3 stops rotating, the traction force of the traction mechanism on the shaking part 2 is cancelled, and the shock absorbing spring 11 in the compressed state stretches and recovers its deformation to push the shaking part 2 upward to reset it. In this way, the control device 4 controls the intermittent operation and stop of the motor 3, drives the traction mechanism to make the shaking part 2 reciprocate up and down, so that the human body has a comfortable shaking feeling when resting on the recliner, and achieves the purpose of deep relaxation.

[0041] Embodiment 3:

[0042] This embodiment is a further improvement on the basis of the above-mentioned embodiment 1 or embodiment 2. In order to better implement the present invention, the following structure is particularly adopted:

[0043] like Figure 5As shown, baffles 8 are provided on both sides of the shaking part 2, and sliding grooves 9 are provided on the inner walls opposite to each other of the two baffles 8. A blackout curtain 10 is provided in the sliding groove 9, and one end of the blackout curtain 10 is fixedly connected to the shaking part 2, and the other end of the blackout curtain 10 is slidably matched with the sliding groove 9.

[0044] Based on the above structure, the shade curtain 10 can be opened or closed by pulling the movable end of the shade curtain 10. When the user is resting on the relaxation chair, he can open the shade curtain 10 to bask in the sun, and when there is a lot of external interference or the light is strong, he can close the shade curtain 10 to reduce interference, thereby creating a quieter and more private resting space.

[0045] Embodiment 4:

[0046] This embodiment is a further improvement on the basis of the above-mentioned embodiment 1, embodiment 2 or embodiment 3. In order to better implement the present invention, the following structure is particularly adopted:

[0047] like Figure 6 As shown, a cushion body 12 is further provided on the upper surface of the shaking part 2. The cushion body 12 can be fixed on the shaking part 2 or detachably provided on the shaking part 2. The cushion body 12 is embedded with a micro vibrator 13 connected to a power source. When a human body lies on the relaxation chair to rest, the micro vibrator 13 can massage the human body.
