[0024] Working principle: When using this adjustable lumbar massage chair, the outer shell 1 serves as the main outer shell of the massage chair, protecting the internal structure and providing an aesthetic appearance. The power supply box 2 is installed at the bottom of the outer shell 1, supplying power to the various components of the massage chair via cables. Mounting bracket 1 3 is an arc-shaped frame that fits the seat and is connected to mounting bracket 2 4 by bolts. Together, they form the main internal support frame of the massage chair. Furthermore, as the bottom of the back support bracket 6 rotates, it connects to the seat support bracket 5, forming an L-shaped seat frame structure. Both the seat support bracket 5 and the back support bracket 6 are U-shaped with aligned openings, providing support for the integrated seat surface 7. Since the lumbar and back adjustment component 8 is installed on the surface of the back support frame 6, the support frame 801 is T-shaped, and its rod passes through the adjustment frame 802. The surface of the rod can be slidably connected to the two adjustment frames 802. The bottom slide of the adjustment frame 802 is threadedly connected to the double threaded screw 803. When the double threaded screw 803 rotates, due to the thread transmission principle, the adjustment frame 802 will slide laterally on the rod of the support frame 801. By sliding, the lateral position of the adjustment frame 802 in the lumbar and back area can be changed, thereby adjusting the width of the massage coverage area to adapt to the lumbar and back width of different users. The slide on one side of the bogie 804 slides in contact with the surface of the double threaded screw 805. When the double threaded screw 805 rotates, the bogie 804 will slide on the support frame 806. At the same time, because it is rotatably connected to the adjusting frame 802, it can also rotate at a certain angle, so that the position and angle of the electric massage head 807 can be further finely adjusted and accurately targeted at different parts of the user's waist and back. After the electric massage head 807 is powered on, the internal motor drives the massage structure to operate, and massages the user's waist and back through the integrated seat surface 7. After the adjustment frame 802 and the steering frame 804 are adjusted to their positions, the electric massage head 807 can perform precise massage on specific waist and back areas of the user. Different users can change the position and angle of the electric massage head 807 according to their own needs by adjusting the double threaded screw one 803 and the double threaded screw two 805, so as to obtain a personalized massage experience that matches the user's desired state, thus increasing the overall practicality.
