[0021] Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present disclosure.

[0022] refer to Figure 1-Figure 7 .

[0023] The present invention provides a waist health care bed, comprising a bed frame 1, an upper body support pad 2, a hip support pad 3, a foot support pad 4, an eccentric swing component mechanism 5, and a reset tension spring 6; the bed frame 1 comprises an upper body support frame 10, a hip support frame 11, and a foot support frame 12, the upper body support frame 10 and the foot support frame 12 are respectively connected to both sides of the hip support frame 11, the upper body support pad 2 and the foot support pad 4 are respectively fixedly connected to the top of the upper body support frame 10 and the foot support frame 12, one end of the hip support pad 3 is hinged to one side of the top of the hip support frame 11 and can swing up and down; the eccentric swing component mechanism 5 is arranged on the hip support frame 11 and is used to drive the hip support pad 3 to swing back and forth on the hip support frame 11; the reset tension spring 6 is connected between one end of the hip support pad 3 and one side of the hip support frame 11 and is used to drive the hip support pad 3 to swing and reset.

[0024] Its working principle is that initially, the buttocks support pad 3 is in a horizontal state. When performing lumbar vertebrae physiotherapy, the user lies supine on the health care bed, with the upper body, buttocks, and feet supported on the upper body support pad 2, the buttocks support pad 3, and the foot support pad 4, respectively. The buttocks support pad 3 is driven to swing up and down on the buttocks support frame 11 by the eccentric swing component mechanism 5. During the upward swing of the buttocks support pad 3, the buttocks support pad 3 will drive the user's buttocks to rise until it reaches the set highest point; when the eccentric swing component mechanism 5 drives the buttocks support pad 3 to swing down, the buttocks support pad 3 can quickly swing down and reset under the tension of the reset tension spring 6, so that the user's buttocks are instantly suspended in the air and perform free fall motion, so as to increase the stretch of the lumbar spine, help reduce the pressure on the lumbar intervertebral disc, increase the width of the intervertebral space, help restore and maintain the normal lumbar curvature, play a good health care role, and can also be used as an ordinary bed.

[0025] Based on the above embodiment, the eccentric swing assembly mechanism 5 includes a motor 50, an eccentric wheel assembly 51, and a connecting rod 52 installed on one side of the hip support frame 11. The eccentric wheel assembly 51 includes an eccentric hole 510. The eccentric wheel assembly 51 is drivingly connected to the motor 50. One end of the connecting rod 52 is hinged on the eccentric hole 510, and the other end of the connecting rod 52 is hinged on the bottom of the hip support pad 3. Specifically, when the motor 50 is working, it will drive the eccentric wheel assembly 51 to rotate, and the rotating eccentric wheel assembly 51 will drive the connecting rod 52 to make an eccentric movement, thereby driving the hip support pad 3 to swing up and down, which has the advantages of simple structure and small wear of parts.

[0026] Based on the above embodiment, the eccentric wheel assembly 51 comprises a bearing seat 511, an expansion sleeve 512 connected to the output shaft of the motor 50, a one-way bearing 513 connected between the bearing seat 511 and the expansion sleeve 512, and a bearing cover 514 installed on the bearing seat 511. The eccentric hole 510 is arranged on the bearing cover 514. When the motor 50 is working, it will drive the expansion sleeve 512, the one-way bearing 513, and the bearing cover 514 to rotate, and the connecting rod 52 that performs eccentric motion will drive the hip support pad 3 to swing up and down. Since the one-way bearing 513 can only rotate in one direction, when the eccentric wheel assembly 51 exceeds the highest critical point during the continuous driving process of the motor 50, the one-way bearing 513 loses the reaction force. Due to the weight of the body hip and the reset tension spring 6, the hip support pad 3 is instantly pulled down to a low position, and the hip is suspended and falls freely, so as to increase the stretch of the lumbar spine, reduce the pressure of the lumbar intervertebral disc, increase the width of the intervertebral space, help to restore and maintain the normal lumbar curvature, play a good health care role, and can also be used as an ordinary bed.

[0027] Based on the above embodiment, a waist support airbag 7 is provided on one side of the top of the upper body support pad 2. When the user lies on his back on the health-care bed, the waist support airbag 7 can support the waist.

[0028] Based on the above embodiment, a ventilation window 20 is provided through the upper body support pad 2 to ventilate the user's head.

[0029] Based on the above embodiment, a frame 110 is provided on the hip support frame 11, and the eccentric swing assembly mechanism 5 is arranged inside the frame 110 to reduce noise and improve aesthetics. A socket 111 electrically connected to the motor 50 is provided on the frame 110 to facilitate power connection of the motor 50.

[0030] Based on the above embodiment, the foot support frame 12 is symmetrically provided with a shaft connection seat 120 on both sides, and a shaft hole is provided on the shaft connection seat 120. The hip support frame 11 is provided with a shaft 112 on both sides corresponding to the shaft hole, and the shaft 112 is connected to the shaft hole. When the hip support pad 3 swings, the shaft 112 will rotate on the shaft hole.

[0031] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
