The rotating support mechanism 31 is used to support the movable mechanism 32 and drive the movable mechanism 32 to rotate.

[0050] Furthermore, the rotating support mechanism 31 is provided with a mounting component for the first transmission connecting rod 21. The mounting component, the fixed connection between the rotating support mechanism 31 and the second support component 52, the transmission connecting shaft, and the transmission assembly 23 cooperate to form a parallelogram, thereby accurately reflecting the real-time rotation angle of the rotating support mechanism 31. In a specific implementation of Embodiment 1 of this utility model, the movable mechanism 32 further includes a linkage unit 322 and a drive unit 321 for driving the linkage unit 322.

The linkage sleeve is used to rotatably connect the linkage member 3221 to the rotating support mechanism 31, thus facilitating the rotation of the linkage member 3221.

[0059] Furthermore, the linkage 3221 is L-shaped. The L-shape of the linkage 3221 allows for a larger rotation angle and makes the rotation process around the rotating support mechanism 31 more stable.

[0060] See Figure 1 In a specific implementation of Embodiment 1 of this utility model, the transmission structure further includes a power supply component 511, which is disposed on the first support member 51. The power supply component 511 is used for power supply.

[0061] Furthermore, the power supply component 511 in Embodiment 1 of this utility model includes a power module and a switch socket. After the switch socket is connected to power, the socket is connected to power to supply power to the power module, which in turn supplies power to the main control board 42 and the drive mechanism 1.

[0062] The working principle of the transmission structure provided in Embodiment 1 of this utility model is as follows:

[0063] See Figures 1 to 6 First, the drive mechanism 1 receives a signal from the main control board 42 and begins to operate. At this time, the first drive rod 11 and the second drive rod 12 extend and retract, driving the rotary support mechanism 31 to rotate. Simultaneously, the first transmission connecting rod 21 and the second transmission connecting rod 22 move, thereby causing the first transmission component 231 and the second transmission component 232 to mesh and rotate. Through the magnetic attraction component on the second transmission component 232 cooperating with the magnetic angle sensor on the main control board 42, the rotation angle signal of the rotary support mechanism 31 is transmitted to the detection component on the main control board 42, and the detection component provides feedback on the rotation angle of the rotary support mechanism 31. When it is necessary to adjust the rotation angle of the movable mechanism 32, the movable switch 3213 is pressed or lifted, and the third drive rod 3211 and the fourth drive rod 3212 perform corresponding actions, thereby causing the linkage component 3221 and the reinforcing component 3222 to rotate, so that the rotary support mechanism 31 is at a new rotation angle.

[0064] Example 2

[0065] This utility model provides a multifunctional lumbar spine rehabilitation device in embodiment 2. See also Figure 7 and Figure 8 It includes a multifunctional lumbar spine rehabilitation device body 6 and a transmission structure as shown in Example 1, the transmission structure being connected to the multifunctional lumbar spine rehabilitation device body 6.

[0066] In a further embodiment of this utility model, the multifunctional lumbar spine rehabilitation device body 6 is equipped with an emergency stop / reset switch 61 for controlling the emergency stop and reset of the transmission structure. The emergency stop / reset switch 61 is connected to the main control board 42. During exercise, if the user feels discomfort and presses the emergency stop / reset switch 61, the current training process will be terminated, and the multifunctional lumbar spine rehabilitation device will return to a zero-degree angle for easy access for the user.

[0067] In the specific implementation of Embodiment 2 of this utility model, the multifunctional lumbar spine rehabilitation device body 6 is further provided with a light source 7, and the light source 7 is fixedly connected to the second support member 52 through a lamp holder.

[0069] In a further embodiment of this utility model, the multifunctional lumbar rehabilitation device also includes a frosted acrylic panel (not shown in the figure), with both the first support member 51 and the second support member 52 having a frosted acrylic panel. The frosted acrylic panel is used to decorate the transmission structure in embodiment 1, protect the transmission structure from pinching or touching electronic components, and also provides sound insulation to reduce noise during operation. The LED light source 7, in conjunction with the frosted acrylic panel, makes the light spot softer.

[0070] In a further embodiment of this utility model, the multifunctional lumbar spine rehabilitation device body 6 is also provided with a soft pad, which is disposed on the first support member 51 and the second support member 52. The soft pad is adapted to the curve of the spine when the human body is in a prone position, and can simultaneously relax the user's spine, shoulders and neck.

[0071] By applying the transmission structure in Example 1 to existing lumbar spine rehabilitation equipment, the problem that the transmission structure in the prior art is extremely inconvenient to use due to its inability to detect rotation angle and poor coordination can be solved.

[0072] In summary, this invention rotatably connects the first drive rod 11 and the second drive rod 12 to the rotating support mechanism 31. The rotating support mechanism 31 is connected to the main control board 42 via the first transmission connecting rod 21 and the second transmission connecting rod 22. This allows the drive mechanism 1 to drive the rotating adjustment mechanism 3 to rotate, and the main control board 42 to accurately detect the rotation angle of the rotating support mechanism 31. This invention features a highly coordinated transmission structure, which not only improves the user experience but also enhances product quality and market competitiveness. Furthermore, this invention is simple to operate and suitable for rehabilitation treatment of patients with lumbar spine diseases.
