Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 The electric lumbar support of this utility model includes a mounting shell 1, a movable slide 2 installed inside the mounting shell 1, a drive mechanism for moving the movable slide 2, and a guide mechanism for guiding the movable slide 2. The drive mechanism includes a drive motor 3, a screw 4 installed at the output end of the drive motor 3, and a nut 5 screwed to the screw 4. The nut 5 is installed on the movable slide 2. The front and rear ends of the movable slide 2 are respectively provided with a first bearing 6 and a second bearing 7. The screw 4 passes through the first bearing 6, the nut 5, and the second bearing 7 in sequence. The screw 5 is integrally formed with the output end of the drive motor 3. A massage component or a ventilation component is installed on the movable slide. The output shaft of the drive motor 4 is integrally formed with the screw 4, making the rotation of the screw 4 more stable and avoiding noise caused by shaking. The screw 4 passes directly through the movable slide 2 through the first bearing 6, the nut 5, and the second bearing 7 in sequence. The movable slide 2 moves synchronously through the nut 5. The first bearing 6 and the second bearing 7 not only support the screw 4 but also make the screwing connection between the nut 5 and the screw 4 more stable, improving the operating stability of the movable slide 2. The drive motor 3 drives the screw 4 to rotate, enabling the movable slide 2 to move up and down simultaneously. A massage component 8 or a ventilation component 9 can be installed on the movable slide 2 as needed. Two nuts 5 are installed on the movable slide 2 to improve operational stability.
