[0002] As an important part of modern automobiles, the design and manufacture of car seats reflect a high level of concern for the comfort and safety of drivers and passengers. Car massage seats are an important comfort configuration in modern automobiles. They provide massage services to drivers and passengers through built-in electric massage devices to relieve fatigue and improve riding comfort.

[0003] Existing car massage seats generally generate vibrations through the vibration motor inside the seat, which acts on the human body with different frequencies and intensities, helping to relieve muscle tension, or use the inflation and deflation of airbags to squeeze the massage parts, simulating the feeling of manual kneading, and providing a comfortable massage experience for the driver and passengers. However, the massage positions of existing car massage seats are fixed, and massage can only be performed at fixed positions and cannot adapt to the massage needs of different parts of the human body, thereby reducing the overall practicality of the device.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the cooperation of the rotating block and other parts, when the massage roller moves upward to the specified position, the third drive motor and the second drive motor are started, and the output end of the second drive motor drives the massage roller to rotate to massage the user's legs. The output end of the third drive motor can be forward and reverse, and the forward and reverse interval is 120 degrees. When the output end of the third drive motor drives the rotating block to swing back and forth, so that the roller swings from the highest point to the lowest point of the arched ramp, the roller gradually extends under the action of the connecting spring, thereby driving the second spur gear to rotate through the second spur rack, and then driving the first spur rack to drive the tray to move upward, so that the massage roller can always fit on the inner inclined slope of the massage seat during the swinging process, so that the device can perform massages at different positions, thereby improving the comfort of the user; 2.

Since the support part of the massage seat is inclined from the outside to the inside, and since the pitches of the outer wall threads of the multiple one-way threaded screws increase in an arithmetic progression, the pitches of the threads of the multiple one-way threaded screws from left to right are smaller. When the multiple one-way threaded screws rotate synchronously, they respectively drive a massage roller to move upward. Finally, when the first drive motor stops running, the multiple massage rollers are distributed in a stepped manner on the inner side of the massage seat, so that the stepped massage rollers can adapt to the tilted state of the legs of the user sitting on the massage seat, so that the device can better massage the user's legs; 3. By arranging the cooperation of parts such as hydraulic dampers, when the massage roller is in the process of massaging and the user suddenly generates a large downward pressure, when the massage roller is in a vertical state, the output end of the hydraulic damper can be squeezed downward when it is subjected to downward pressure, thereby buffering; when the massage roller is in an inclined state, the massage roller can adaptively drive the rotating block to rotate when it is subjected to downward pressure, thereby causing the torsion spring to twist, so that it can be retracted to a position, thereby preventing the user from being injured by a sudden excessive downward force, thereby improving the safety of the device and further improving the overall practicality of the device.
