TECHNICAL FIELD

[0001] The present application relates to the technical field of passive exercise apparatuses, in particular to a massage chair. BACKGROUND

[0002] Massage chairs use mechanical rolling force and mechanical force to perform massage. Artificial massage can dredge the meridians, circulate blood, and maintain the balance of yin and yang of the body. Therefore, after massage, people can feel muscle relaxation, joint flexibility, and mental stimulation, which can eliminate fatigue and play an important role in ensuring physical health.

[0003] The massage chair in the prior art, such as Chinese invention application CN113509366A, generally only supports and fine-tunes the seat of the massage chair. The massage function and the movement function of the massage chair are concentrated on the seat.

[0004] Therefore, the structure of the massage chair determines that the massage chair cannot drive the human body to perform continuous overall movement and massage. SUMMARY

[0005] In order to realize that the massage chair can drive the human body to perform overall movement, the present application provides a locking massage chair, and the technical scheme is as follows.

[0006] The massage chair comprises a seat and a driving device arranged below the seat.

The connecting rod is hingedly connected with the connecting frame, and the roller surface is in rolling contact with the connecting frame. The up-and-down shaking device and the four-bar linkage device are arranged on the bottom plate. The top of the up-and-down shaking device is connected with the connecting frame, and the four-bar linkage device is hingedly connected with the connecting frame. The up-and-down shaking device drives the connecting frame to move.

[0007] The up-and-down shaking device comprises a power device and an eccentric mechanism. The power device drives the eccentric mechanism to move. The eccentric mechanism comprises an eccentric wheel, a driving shaft, and a connecting piece. The eccentric wheel is fixedly installed on the driving shaft, and the eccentric wheel drives the connecting piece to move up and down. The power device drives the driving shaft to rotate, and the driving shaft drives the eccentric wheel to rotate.

[0008] The eccentric mechanism further comprises a swing seat. The swing seat has two bearing holes. One of the bearing holes is connected with the connecting piece through a bearing and an axial shoulder screw. The eccentric wheel is connected with the other bearing hole through a bearing.

[0009] A driven wheel is further arranged on the driving shaft, and the driven wheel is connected with the power device through a synchronous belt.

[0010] The four-bar linkage device comprises a horizontal rod and at least two V-shaped rods. The V-shaped rod comprises a short side and a long side. The horizontal rod is hingedly connected with the short side of the V-shaped rod at both ends. The middle of the V-shaped rod is hingedly connected with the bottom plate. The long side of the V-shaped rod is hingedly connected with the connecting frame.

[0011] The bottom plate is provided with at least two four-bar linkage devices.

[0012] The driving shaft is provided with at least two eccentric wheels.

[0013] The foot cup is arranged below the bottom plate.

DETAILED DESCRIPTION

[0025] To achieve the above technical purposes, the technical scheme of the present application provides a massage chair, and the technical scheme is as follows:

[0026] As Figure 1 ,2 The massage chair shown, including a seat A and a drive device arranged below the seat A, the drive device comprising a bottom plate 1, a connecting frame 2, an up-and-down shaking device 3 and a four-bar linkage device 4, the seat A is fixedly provided with a connecting rod at the bottom, and a rolling roller 5 is arranged on the connecting rod, the connecting rod is hingedly connected with the connecting frame 2, the surface of the roller 5 rolls in contact with the connecting frame 2, the up-and-down shaking device 3 and the four-bar linkage device 4 are arranged on the bottom plate 1, the top of the up-and-down shaking device 3 is connected with the connecting frame 2, the four-bar linkage device 4 is hingedly connected with the connecting frame 2, and the up-and-down shaking device 3 drives the connecting frame 2 to move.

[0027] As shown in Figure 3 , in actual operation, the power device 6 is arranged as an electric motor, the power device 6 rotates through a synchronous belt driven wheel 75, the driven wheel 75 is fixedly connected with a driving shaft 72, which can be integrally cast, and can be a key or a pin, the rotating driven wheel 75 drives the driving shaft 72 to rotate together.

[0028] As shown in Figure 3 , 4 , 5, 6 and 7, an eccentric wheel 71 is sleeved on the driving shaft 72, the outer surface of the eccentric wheel 71 is connected with a bearing, and the bearing is installed in a bearing hole of a swing seat 74, the rotation of the driving shaft 72 drives the eccentric wheel 71 to rotate together, the outer surface of the eccentric wheel 71 drives the bearing of the driving shaft 72 to make eccentric motion, because the bearing is installed in the bearing hole, the bearing drives the swing seat 74 to move up and down, another bearing hole of the swing seat 74 is connected with a connecting plate 73 through a shaft screw, so the swing seat 74 drives the connecting plate 73 to move up and down, the top of the connecting plate 73 is fixedly connected with the connecting frame 2, so the eccentric wheel 71 drives the connecting frame 2 to move up and down.

[0029] As shown in Figure 5 , when the connecting frame 2 moves up and down, the long end of the V-shaped rod 41 hingedly connected with the connecting frame 2 is driven by the connecting frame 2 to move up and down together, because the middle of the V-shaped rod 41 is hingedly connected with the bottom plate 1, and the short end of the V-shaped rod 41 is connected with a cross rod 42, so the upper part of the entire massage chair is actually placed on the connecting rod, and the V-shaped rod 41 forms a connecting rod because of the three hinged points, so it can ensure that the motion of at least two points remains consistent under the drive of the cross rod.

[0030] In actual operation, in order to ensure the stability of the massage chair, two four-bar linkage devices 4 are arranged, the upper part of the entire massage chair is arranged on the four-bar linkage devices 4, the two four-bar linkage devices 4 can drive the massage chair while increasing the load bearing capacity of the massage chair, and because the two cross rods are parallel to each other in actual operation, the up-and-down shaking of the entire massage chair is consistent.

[0031] In order to adapt to different ground environments, a foot cup 9 is arranged below the bottom plate 1, which can conveniently adjust the height of each of the four feet to adapt.

[0032] The bottom of the seat A is fixedly provided with a connecting rod hinged with the connecting frame 2 and a roller 5 provided with a surface rolling contact with the connecting frame 2.

[0033] The setting of the roller 5 makes the connecting action between the seat A and the connecting frame 2 more smooth and fluent, improving the experience of the user.

[0034] In order to better the user experience, a pressure sensor is further provided on the seat A of the massage chair, the pressure sensor is arranged at a part of the seat corresponding to the buttocks, when the pressure sensor senses a sustained weight, the speed of the motor can be regulated, thereby regulating the frequency of the up and down shaking, when the pressure sensor does not sense the weight, the motor can only run at the specified speed.

[0035] It can be understood that the above specific description of the present application is only used to illustrate the present application and is not limited to the technical solutions described in the embodiments of the present application. Those skilled in the art should understand that the present application can still be modified or replaced equivalently to achieve the same technical effect; as long as the motor is installed in the square steel of the lock body, and automatic unlocking and locking of the lock body are realized through the quick and fast locking function, it is within the protection scope of the present application.
