[0018] The automobile seat slide rail can convert sliding friction into rolling friction through the provided rotation groove, damping pad, roller shaft and roller, thereby reducing resistance during seat adjustment and improving smoothness.
[0019] The automobile seat slide rail can ensure that the interior of the same group of slide rail systems can be adjusted simultaneously through the terminal blocks, terminal beams, inner grooves, empty channels, driven transmission shafts, active transmission shafts, cable reels, transmission connecting cables and toggle plates, and ensures that both sides of the same group of systems can be locked and unlocked at the same time.

[0047] Working principle: During installation, connect the seat docking plate 107 to the bottom of the seat and connect the vehicle body docking plate 108 to the vehicle floor;
[0048] During normal use, press down the upper toggle piece 209. The toggle piece 209 drives the active transmission shaft 206 to rotate. The active transmission shaft 206 drives the cable reel 207 on its surface to rotate. The cable reel 207 drives another cable reel 207 to rotate by winding the transmission connecting cable 208 during rotation, so that the driven transmission shaft 205 rotates synchronously with the active transmission shaft 206. When the driven transmission shaft 205 and the active transmission shaft 206 rotate, they drive the surface rotating pressure seat 504, positioning wheel 507 and eccentric wheel 401 to rotate. When the rotating pressure seat 504 rotates, it presses down the reset reed 505 to deform and store energy. When the positioning wheel 507 rotates, the positioning between the positioning groove 508 and the positioning block 509 is released. When the eccentric wheel 401 rotates, it drives the lifting block 402 to rise, and when the pulling block 403 rises, it slides horizontally along the relief cross groove 405. At the same time, the rising of the lifting block 402 pulls the horizontal sliding seat 404 and the lifting clamping block 303 to rise. At this time, the upper slide rail 105 slides along the middle slide seat 103, so as to adjust the front and rear position of the seat. After the adjustment is completed, release the upper toggle piece 209. The reset reed 505 rebounds and pushes the rotating pressure seat 504 to reset until the rotating pressure seat 504 is blocked by the gear seat 503. When the rotating pressure seat 504 resets, it drives the driven transmission shaft 205 and the active transmission shaft 206 to rotate and reset respectively. The transmission connecting cable 208 is driven by the rotating cable reel 207 to wind. When the driven transmission shaft 205 and the active transmission shaft 206 rotate, they also drive the positioning wheel 507 and the eccentric wheel 401 to rotate, so that the positioning groove 508 is clamped with the positioning block 509. At the same time, the rotation of the eccentric wheel 401 drives the lifting block 402 to descend, so that the lifting block 402 pushes the horizontal sliding seat 404 and the lifting clamping block 303 to reach the lowest point, so that the center of the eccentric wheel 401 and the eccentric connection line are perpendicular to the bottom surface of the lifting block 402, avoiding the reverse push of the lifting block 402. At the same time, the roller groove 305 is clamped and locked with the rotating roller 112, so as to position the seat;
[0049] When using the upper track system after it is damaged, press down the lower toggle piece 209. The toggle piece 209 drives the active transmission shaft 206 to rotate. The active transmission shaft 206 drives the cable reel 207 on its surface to rotate. The cable reel 207 drives another cable reel 207 to rotate by winding the transmission connecting cable 208 during rotation, so that the driven transmission shaft 205 rotates synchronously with the active transmission shaft 206. When the driven transmission shaft 205 and the active transmission shaft 206 rotate, they will drive the rotating pressure seat 504, the positioning wheel 507 and the eccentric wheel 401 on their surfaces to rotate. When the rotating pressure seat 504 rotates, it presses down the reset reed 505 to deform and store energy. When the positioning wheel 507 rotates, the positioning between the positioning groove 508 and the positioning block 509 is released. When the eccentric wheel 401 rotates, it drives the lifting block 402 to rise, and when the pulling block 403 rises, it slides horizontally along the relief transverse groove 405. At the same time, the rising of the lifting block 402 pulls the horizontal sliding seat 404 and the lifting clamping block 303 to rise. At this time, the middle slide rail 101 slides along the lower slide seat 106, thereby adjusting the front-back position of the seat. After the adjustment is completed, release the lower toggle piece 209. The reset reed 505 rebounds and pushes the rotating pressure seat 504 to reset until the rotating pressure seat 504 is blocked by the gear seat 503. When the rotating pressure seat 504 resets, it will drive the driven transmission shaft 205 and the active transmission shaft 206 to rotate and reset respectively. The transmission connecting cable 208 is driven by the rotating cable reel 207 to wind. When the driven transmission shaft 205 and the active transmission shaft 206 rotate, they also drive the positioning wheel 507 and the eccentric wheel 401 to rotate, so that the positioning groove 508 is clamped with the positioning block 509. At the same time, the rotation of the eccentric wheel 401 drives the lifting block 402 to descend, so that the lifting block 402 pushes the horizontal sliding seat 404 and the lifting clamping block 303 to reach the lowest point of the position, so that the center of the eccentric wheel 401 and the eccentric connection line are perpendicular to the bottom surface of the lifting block 402, avoiding the reverse push of the lifting block 402. At the same time, the roller groove 305 is clamped and locked with the rotating roller 112, thereby positioning the seat.
[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
