[0034] Specifically, a car seat is an important component inside a car, and its main function is to provide a seat that is easy to operate and comfortable to ride for the driver and passengers. During the use of the car seat, a seat back lumbar support control device is required to facilitate support and adjustment of the back lumbar support.

[0035] The existing automobile seat back lumbar support adjustment device can adjust the height and position of the back lumbar support body when in use. However, when the driver sits for a long time, the waist may become sore, and it is inconvenient for the driver to massage the waist during driving, which may easily cause fatigue to the driver and affect normal driving. Therefore, in order to solve the above problems, when the present embodiment is in use, when the driver's waist is sore, the motor 5 23 can be used to drive the crank 24 to rotate, and the crank 24 drives the slider 25 to rotate continuously, so that the slider 25 slides back and forth in the slide groove of the reciprocating rod 26, that is, the reciprocating rod 26 slides back and forth on the reciprocating block 31, so that the rotating roller 14 intermittently approaches the driver's waist. At the same time, the motor 4 22 can be used to drive the rotating roller 14 to rotate, and the convex block 29 can be used to massage the driver's waist to help the driver relieve the soreness of the waist. At the same time, the motor 6 27 can be used to drive the threaded rod 3 19 to rotate, so that the reciprocating block 31 slides back and forth on the slide rod 4 20, and the orientation of the rotating roller 14 is adjusted to achieve the purpose of uniform massage, thereby avoiding the situation that when the driver's waist is sore, it is inconvenient to massage the waist to relieve the soreness, which makes the driver more tired and affects normal driving. Furthermore, when the rotating roller 14 massages the driver's waist, the driver's waist may slip due to the push of the rotating roller 14, resulting in the waist not being in the middle area of ​​the seat. The driver needs to frequently adjust his body, which affects normal driving. Therefore, in order to avoid this situation, according to the width of the driver's waist, the motor 3 15 is used to drive the bidirectional threaded rod 17 to rotate, so as to adjust the spacing between the two adjustment rods 8, and the electric push rod 11 is used to drive the frame 13 to approach the driver's waist until the two limit columns 16 form a protrusion on the surface of the lumbar support pad 7 and limit the driver's waist between the two limit columns 16. At this time, when the rotating roller 14 massages the driver's waist again, even if the driver's waist is subjected to external force, it will not slip, thereby avoiding the situation where the driver needs to frequently adjust his body, thereby affecting normal driving.

[0036] Working principle: The mounting plate 1 can be installed inside the car seat by using the mounting hole 30. According to the waist height of the passenger, the motor 25 can be used to drive the threaded rod 29 to rotate, so that the lifting plate 6 can move up and down to adjust the height of the lumbar support pad 7 to adapt to passengers of different heights. In addition, the motor 12 can be used to drive the threaded rod 13 to rotate, so that the adjustment plate 4 can slide on the slide rail 28 to adjust the protrusion of the lumbar support pad 7 to adapt to different usage requirements. When the driver's waist is sore, the motor 5 23 can be used to drive the crank 24 to rotate, and the crank 24 can be used to adjust the height of the lumbar support pad 7. The movable slider 25 makes a circular motion. Since the slider 25 can rotate on the crank 24, when the slider 25 makes a circular motion, it also slides back and forth in the slide groove of the reciprocating rod 26, so that the reciprocating rod 26 can slide back and forth on the reciprocating block 31, so that the rotating roller 14 is intermittently close to the driver's waist. At the same time, the motor 22 can drive the rotating roller 14 to rotate, and the convex block 29 can be used to massage the driver's waist to help the driver relieve the soreness of the waist. At the same time, the motor 6 27 can drive the threaded rod 3 19 to rotate, so that the reciprocating block 31 The sliding rod 20 reciprocates and adjusts the position of the rotating roller 14 to achieve the purpose of uniform massage, thereby avoiding the situation that when the driver's waist is sore, it is inconvenient to massage the waist to relieve it, causing the driver to be more tired and affecting normal driving; and, because when the rotating roller 14 massages the driver's waist, the driver's waist may slip due to the push of the rotating roller 14, causing the waist to be not in the middle area of ​​the seat, requiring the driver to frequently adjust the body, affecting normal driving. Therefore, in order to avoid this situation, according to the width of the driver's waist, the motor 3 15 is used to drive the bidirectional threaded rod 17 to rotate, so as to adjust the spacing between the two adjusting rods 8, and the electric push rod 11 is used to drive the frame 13 to approach the driver's waist, until the two limiting columns 16 form a bulge on the surface of the lumbar support pad 7, and the driver's waist is limited between the two limiting columns 16. At this time, when the rotating roller 14 massages the driver's waist again, even if the driver's waist is subjected to external force, it will not slip, avoiding the need for the driver to frequently adjust the body, thereby affecting normal driving.Therefore, by utilizing the limited position massage mechanism, when the driver's waist is sore, the rotating roller 14 can be driven to intermittently approach the driver's waist, and at the same time, the rotating roller 14 can be driven to rotate, and the driver's waist can be massaged by the convex block 29 to help the driver relieve the soreness of the waist. At the same time, the reciprocating block 31 can be driven to slide back and forth on the sliding rod 20 to adjust the position of the rotating roller 14 to achieve the purpose of uniform massage, thereby avoiding the situation that when the driver's waist is sore, it is inconvenient to massage the waist to relieve it, causing the driver to be more tired and affecting normal driving. Moreover, according to the width of the driver's waist, the motor 3 15 can be used to drive the bidirectional threaded rod 17 to rotate, so as to adjust the distance between the two adjusting rods 8, and the electric push rod 11 can be used to drive the frame 13 to approach the driver's waist until the two limiting columns 16 form a bulge on the surface of the lumbar support pad 7 and the driver's waist is limited between the two limiting columns 16. At this time, when the rotating roller 14 massages the driver's waist again, even if the driver's waist is subjected to external force, it will not slip, thereby avoiding the situation where the driver needs to frequently adjust his body, thereby affecting normal driving. The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
