[0021] like Figure 1-4As shown, a car seat frame that is easy to adjust includes three seat frames, wherein the seat frame on the far left includes a backrest 1 and a seat frame 2, a recliner assembly is provided between the backrest 1 and the seat frame 2, and a floor lock 3 is provided on the recliner assembly, the seat frame 2 is locked to the upper surface of the slide rail 4 through the floor lock 3, the slide rail 4 is slidably set on the track 23, and the slide rail 4 is rotatably connected to two locking assemblies fixed on the left and right sides of the front end of the seat frame, the locking assembly is inserted into the track 23 to limit the sliding of the slide rail 4, the seat frame 2 can rotate counterclockwise around the locking assembly, and when the seat frame 2 rotates counterclockwise, the locking assembly is unlocked, so that the slide rail 4 can slide along the track 23, and a pull wire 5 for controlling the rotation limit of the floor lock 3 is provided on the backrest 1, and the floor lock 3 is used to limit the rotation of the seat frame 2 and lock the seat frame 2 on the slide rail 4. The floor lock 3 can be used as an optional The model is HYLX98-00L / R. One end of the pull wire 5 is set on the backrest 1, and the other end of the pull wire 5 is connected to the ground lock 3 for controlling the opening and closing of the ground lock 3. When the pull wire 5 is pulled, the ground lock 3 can be unlocked. At this time, the seat frame 2 can rotate around the locking assembly. When the seat frame 2 rotates, it can drive the locking assembly to operate, and the limit of the slide rail 4 and the track 23 can be released. When the locking assembly releases the restriction, the seat frame 2 can move along the track 23 with the slide rail 4 to the appropriate position, and the seat frame 2 is rotated and reset. The locking assembly resets and locks the slide rail 4 to limit the slide rail 4. The seat frame is used for a three-row car. The seat frame is the second row seat frame in the three rows of seats. Adjust the leftmost seat frame to facilitate passengers to sit in the third row of seats, or for passengers in the third row of seats to get off the car. The adjuster assembly is used to adjust the inclination angle of the backrest.

[0022] In this embodiment, the recliner assembly includes a recliner 6, which is installed between an upper connecting plate 7 and a lower connecting plate 8. The upper connecting plate 7 is fixed to the backrest 1, the lower connecting plate 8 is fixed to the seat frame 2, and the floor lock 3 is installed on the lower connecting plate 8. The model of the recliner 6 is QTF04. The angle of rotation of the upper connecting plate 7 is adjusted by the recliner 6 to control the angle of rotation of the backrest 1.

[0023] In this embodiment, the locking assembly includes a connecting rod 9 rotatably mounted on the front end of the seat frame 2, the other end of the connecting rod 9 is rotatably mounted on the slide rail 4, a pull wire 2 10 is clamped on the connecting rod 9, the other end of the pull wire 2 10 is fixed on the unlocking connecting piece 11, the unlocking connecting piece 11 is rotatably connected to the slide rail 4, a coil spring 12 is provided at the rotation connection between the unlocking connecting piece 11 and the slide rail 4, the two ends of the coil spring 12 are respectively connected to the unlocking connecting piece 11 and the slide rail 4, the unlocking connecting piece 11 is connected to the positioning assembly, and the positioning assembly is plugged into the track 23 to limit the sliding of the slide rail 4. When the local lock 3 releases the rotation limit of the seat frame 2, it pushes the seat frame 2 to rotate, and the seat When the frame 2 rotates around the axis of the rotation connection position with the connecting rod 9, it can also drive the connecting rod 9 to rotate around the axis of the rotation connection position with the slide rail 4, thereby causing the seat frame 2 to tilt forward. The tilting of the seat frame 2 can make room for passengers in the back seats, making it easier for passengers to get on and off the vehicle. When the seat frame 2 drives the connecting rod 9 to rotate, the connecting rod 9 pulls the pull wire 2 10, and the pull wire 2 10 drives the unlocking connecting piece 11 to rotate around the axis of the connection with the slide rail 4, releasing the limit of the locking assembly, so that the slide rail 4 can move along the track 23. When the seat frame 2 is reset, the coil spring 12 will pull the unlocking connecting piece 11 to reset, and the unlocking connecting piece 11 will lower the locking assembly, and the locking assembly will reset. Similarly, the reset of the unlocking connecting piece 11 will drive the pull wire 2 10 to reset.

[0024] In this embodiment, the locking assembly includes a sleeve plate 13 connected to the unlocking connecting piece 11, and a sleeve groove 14 is provided on the sleeve plate 13, and the sleeve groove 14 is T-shaped. A round rod 15 is fixed to the unlocking connecting piece 11, and one end of the round rod 15 passes through the sleeve groove 14 and can be displaced along the sleeve groove 14. The sleeve plate 13 is fixed to one end of the locking plate 16, and the locking plate 16 is in the shape of a comb without comb teeth. A locking block 17 is fixed on the locking plate 16, and a locking hole 19 that cooperates with the locking block 17 is provided on the track 23. The other end of the locking plate 16 is rotatably set in the slide rail 4. When the unlocking connecting piece 11 rotates, it drives the round rod 15 to rotate, and the round rod 15 rotates upward in the sleeve groove 14 and moves downward. Lift the sleeve plate 13 upwards, and the sleeve plate 13 drives the locking plate 16 to rotate around the rotating shaft connecting the locking plate 16 and the slide rail 4. The locking plate 16 drives the locking block 17 to disengage from the locking hole 19, releasing the limit of the slide rail 4 and the track 23. At this time, the seat frame 2 can be pushed to drive the slide rail 4 to move along the track 23, rotate the backrest 1 on the leftmost seat frame, and then move the seat frame 2 of the leftmost seat frame and rotate it forward, which can make more room for the rear passengers and facilitate passengers to get off the car. When the seat frame 2 is reset, the round rod 15 is reset along with the unlocking connecting piece 11. At this time, the round rod 15 rotates and moves downward in the sleeve groove 14, and the sleeve plate 13 is put down, so that the locking plate 16 and the locking block 17 are lowered, and the locking block 17 is inserted into the locking hole 19 again.

[0025] In this embodiment, a limiting block 18 is fixed on the slide rail 4, a limiting sleeve 20 is clamped on the limiting block 18, the pull wire 2 10 is fixed on the limiting sleeve 20, a guide block 21 is fixed on the slide rail 4, a guide sleeve 22 is clamped on the guide block 21, and the pull wire 2 10 passes through the guide sleeve 22 to prevent the pull wire 2 10 from contacting the guide block 21 and the limiting block 18, thereby preventing it from being worn off, thereby extending the service life of the pull wire 2 10.

[0026] In this embodiment, the slide rail 4 and the track 23 are slidably connected using a ball assembly.

[0027] In this embodiment, the ball assembly includes a ball bracket 24 fixed on the slide rail 4, and a plurality of ball balls 25 are mounted on the ball bracket 24. The ball balls 25 lift the ball bracket 24 in the track 23. The ball slide rail 4 can reduce the sliding noise of the slide rail 4. The ball balls 25 support the track 23 and can fit with the track 23, which also prevents the slide rail 4 from shaking when moving.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
