AI Technical Summary
The slide rail seat of the existing car seat is directly connected to the rear crossbar, resulting in the passenger's center of gravity not changing when adjusting the inclination angle, and only the legs are lifted, bringing a sense of local squeeze, which makes the customer experience poor.
A car seat under-skeleton with adjustable inclination is designed. By connecting the rear lifting arm between the slide rail seat and the seat side plate, during the inclination adjustment, the rear end drops accordingly when the front end rotates and rises, ensuring that the occupant's center of gravity decreases accordingly and avoids the local squeezing feeling.
With this design, the seat cushion curves are smoother when adjusting the inclination angle, greatly improving riding comfort and significantly improving customer experience.

DETAILED DESCRIPTION
[0008] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0009] like Figure 1As shown, the utility model is a lower frame of an automobile seat with adjustable inclination, comprising: a right upper rail 1, a left upper rail 2, a right lower rail 3, a left lower rail 4, a right rail seat 5, a left rail seat 6, a right angle adjuster 7, a left angle adjuster 8, a right angle adjuster bracket 9, a left angle adjuster bracket 10, a right front lifting arm 11, a left front lifting arm 12, a driving motor 13, a front cross tube 14, a rear cross tube 15, a right rear lifting arm 16, a left rear lifting arm 17, a right side plate 18, a left side plate 19 and a synchronization rod 20; the right upper rail 1 is slidably connected to the right lower rail 3; the left upper rail 2 is slidably connected to the left lower rail 4; the right rail seat 5 is fixedly connected to the right upper rail 1; the left rail seat 6 is fixedly connected to the left upper rail 2; the right angle adjuster 7 is fixedly connected to the right rail seat 5; the left angle adjuster 8 is fixedly connected to the left rail seat 6; the right angle adjuster bracket 9 is The right angle adjuster 7 is connected; the left angle adjuster bracket 10 is connected to the left angle adjuster 8; the lower end of the right front lifting arm 11 is hinged to the right angle adjuster bracket 9; the lower end of the left front lifting arm 12 is hinged to the left angle adjuster bracket 10; the upper ends of the right front lifting arm 11 and the left front lifting arm 12 are respectively fixedly connected to the front cross tube 14; the lower end of the right rear lifting arm 16 is hinged to the right slide rail seat 5; the lower end of the left rear lifting arm 17 is hinged to the left slide rail seat 6; the upper ends of the right rear lifting arm 16 and the left rear lifting arm 17 are respectively fixedly connected to the rear cross tube 15; the right side plate 18 and the left side plate 19 are respectively hinged to the front cross tube 14 and the rear cross tube 15; the drive motor 13 is connected to the synchronization rod 20; the two ends of the synchronization rod 20 are respectively connected to the right angle adjuster 7 and the left angle adjuster 8.
[0010] When doing specific operations, such as Figure 2As shown, when the passenger wants to adjust the inclination of the seat cushion to raise the front end of the seat cushion, the driving motor 13 can be operated to run forward, and the driving motor 13 drives the synchronization rod 20 to rotate forward, and the synchronization rod 20 drives the right recliner 7 and the left recliner 8 at the same time, and the right recliner 7 and the left recliner 8 respectively drive the right recliner bracket 9 and the left recliner bracket 10 to rotate counterclockwise in the figure, and the right recliner bracket 9 and the left recliner bracket 10 respectively lift the right front lifting arm 11 and the left front lifting arm 12, and the right front lifting arm 11 and the left front lifting arm 12 are lifted. The arm 12 pushes the front cross tube 14 upward, and the front ends of the right side plate 18 and the left side plate 19 rise, completing the lifting of the front end of the seat cushion. At the same time, due to the lifting of the front ends of the right side plate 18 and the left side plate 19, the rear cross tube 15 hinged at the rear ends thereof is forced to press down the right rear lifting arm 16 and the left rear lifting arm 17, and the rear end of the seat cushion drops accordingly. When the passenger adjusts the inclination of the seat cushion backward and relaxes the body, the center of gravity of the passenger also drops with the seat cushion, avoiding the local squeezing feeling caused by simply raising the legs, greatly improving the riding comfort. The passenger needs to adjust the front end of the seat cushion to drop, and the driving motor 13 can be operated to rotate in the opposite direction.
[0011] The connection relationship and working principle between the drive motor and the synchronization rod, the matching structure and working principle between the synchronization rod and the recliner, and the matching structure and working principle between the recliner and the recliner bracket are all known to those skilled in the art.
[0012] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
