The vibrating head extends out of the upper end surface of the lumbar pad to perform vibrating treatment on the user. Moreover, the lumbar pad is rotatably arranged on the bed frame, and the driving component drives the lumbar pad to rotate so as to drive the lumbar pad to form an angle with the horizontal plane, so that the pressing degree between the user and the vibrating head is better, the vibrating head can better act on the treatment site, and the physiotherapy effect is better.

[0004] Based on the description of the above document, in order to adapt to the vibrating treatment at the spine and scapula of the user and improve the accuracy of treatment, the existing physiotherapy bed often needs to locate the acupoints to achieve the physiotherapy operation. However, for users of different heights, the positions to be massaged are also different. And during the massage process, due to the lack of a support point for the feet, the user will be displaced when vibrating. For this reason, the present invention provides an adaptive actuator for a multifunctional physiotherapy bed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an adaptive actuator for a multifunctional physiotherapy bed, which solves the problems that in order to adapt to the vibrating treatment at the spine and scapula of the user and improve the accuracy of treatment, the existing physiotherapy bed often needs to locate the acupoints to achieve the physiotherapy operation. However, for users of different heights, the positions to be massaged are also different. And during the massage process, due to the lack of a support point for the feet, the user will be displaced when vibrating.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: an adaptive actuator for a multifunctional physiotherapy bed, including a bottom frame, and the bottom frame realizes the lifting operation of the top frame through a pneumatic component.

[0011] The lower connecting plate is fixed at the same position at the bottom of the two moving rods. A return spring is installed between the lower connecting plate and the opposite side of the inner wall of the leg support plate near the backrest plate. When not affected by external forces, the return force of the return spring causes the footrest plate to move towards the leg support plate.

[0083] Please refer to Figures 4 - 5 In the embodiment of the present invention, the adjusting part 7 includes a support plate 71 installed on the left side of the bottom of the backrest plate 4, and a toggle rod 72 is rotatably installed on the surface of the support plate 71. A headrest 3 is connected and fixed to the surface of the toggle rod 72 through a connecting frame 73, and a limiting component 74 is provided at one end of the toggle rod 72.

[0084] Please refer to Figure 4 In the embodiment of the present invention, the limiting component 74 includes:

[0085] A housing 741 is fixedly installed on the left side of the bottom of the backrest plate 4, and a ratchet groove 742 is provided inside the housing 741. The ratchet groove 742 is a groove with the same shape as the ratchet, which is convenient for subsequent control operations.

[0086] A fixed disk 743 is installed at the end of the toggle rod 72, and a ratchet tooth 745 is rotatably installed on the surface of the fixed disk 743 at a position deviated from the center of the circle through a rotating shaft 744, and the ratchet tooth 745 contacts the ratchet groove 742 to achieve clamping.

[0087] By providing the adjusting part 7, the rotation of the toggle rod 72 drives the rotation of the headrest 3 accordingly. Through the rotation of the rotating shaft 744, the ratchet tooth 745 is disengaged from the ratchet groove 742.

[0089] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0090] During operation, after the user lies on the physiotherapy bed and roughly adapts the horizontal positions at the spinal vertebrae and scapulae to the positions of the physiotherapy components, the user drives the moving rod 611 to move by contacting the footrest plate 612 with the feet. The movement of the moving rod 611 causes the small actuating plate 642 to move synchronously. At this time, the actuating force of the small actuating plate 642 on the large actuating plate 641 gradually decreases, and under the restoring force of the actuating spring 643, the large actuating plates 641 move closer to each other;

[0091] This drives the square sleeve 63 to move relatively on the surface of the square rod 62, and drives the synchronous movement of the opening plate 65 and the control plate 81. At this time, the physiotherapy component 66 also moves synchronously;

[0092] Then, by starting the self-locking motor 871 to drive the drive shaft 872 to rotate, the drive shaft 872 realizes the synchronous rotation of the transverse shaft 86 through the sliding limit between the sliding strip 873 and the sliding groove 874. The rotation of the transverse shaft 86 drives the driven bevel gear 852 to rotate synchronously through the main bevel gear 851. The driven bevel gear 852 drives the vertical shaft 83 to rotate. At this time, the rotating gear 881 also rotates. Due to the meshing of the rotating gear 881 with the teeth 882, the rotating gear 881 is driven to roll on the surface of the teeth 882, realizing the movement operation of the control plate 81 inside the opening plate 65, completing a small adjustment of the position of the physiotherapy component 66, facing the acupoints of the user. After positioning, the position is fixed through the existing locking function of the self-locking motor 871;

[0093] At the same time, the rotation of the toggle lever 72 drives the headrest 3 to rotate accordingly. Through the rotation of the rotating shaft 744, the ratchet tooth 745 disengages from the ratchet groove 742. After the toggle lever 72 rotates to a comfortable position, releasing the rotating shaft 744 can realize the clamping and fixing of the ratchet tooth 745 and the ratchet groove 742, thereby completing the adjustment of the user's head posture and making the user more comfortable.

6. The adaptive actuator of a multifunctional physiotherapy bed according to claim 4, characterized in that: The meshing assembly (88) includes a rotating gear (881) fixedly installed on the surface of the vertical shaft (83). The rotating gear (881) is located inside the control plate (81). A tooth (882) is installed on the left side of the inner opening of the opening plate (65). The surface of the rotating gear (881) meshes with the surface of the tooth (882). When the rotating gear (881) rotates, it moves on the surface of the tooth (882).

7. The adaptive actuator of a multifunctional physiotherapy bed according to claim 4, characterized in that: The steering assembly (85) includes a main bevel gear (851) fixedly installed at the end of the horizontal shaft (86), and a sub-bevel gear (852) fixedly installed at the bottom end of the vertical shaft (83). The horizontal shaft (86) is fixed to the L-shaped plate (84) through a rotating bearing. The main bevel gear (851) and the sub-bevel gear (852) are of the same size, and the surfaces of the main bevel gear (851) and the sub-bevel gear (852) mesh with each other.

8. The adaptive actuator of a multi-functional physiotherapy bed according to claim 4, characterized in that: The driving member (87) includes: A self-locking motor (871), installed on the side of the back support plate (4). The drive shaft of the self-locking motor (871) extends to the inner wall of the back support plate (4) and is installed with a drive shaft (872) through a coupling. A relative sliding operation is achieved between the drive shaft (872) and the horizontal shaft (86) through a sliding member. When the drive shaft (872) rotates, it drives the horizontal shaft (86) to rotate synchronously; The sliding member includes a sliding bar (873) installed on the surface of the horizontal shaft (86). A sliding groove (874) adapted to slide with the sliding bar (873) is opened inside the drive shaft (872). The sliding bar (873) slides inside the sliding groove (874) and does not disengage.

9. The adaptive actuator of a multifunctional physiotherapy bed according to claim 1, characterized in that: The adjusting part (7) includes a support plate (71) installed on the left side of the bottom of the back support plate (4). A toggle lever (72) is rotatably installed on the surface of the support plate (71). A headrest (3) is connected and fixed to the surface of the toggle lever (72) through a connecting frame (73).
