Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the swivel seat capable of adjusting the slide rail at any position according to the present invention includes a slide rail assembly 1, a first mounting frame 2, a mounting plate 3, a second mounting frame 4 and a seat frame 5, wherein the slide rail assembly 1 includes a pair of fixed rails 11 and a pair of slide rails 12, the fixed rails 11 are fixedly mounted on the vehicle body, the slide rails 12 are mounted on the corresponding fixed rails 11 along the longitudinal direction, both sides of the first mounting frame 2 are respectively fixedly mounted on the slide rails 12, the mounting plate 3 includes a fixed plate 31 and a rotatable rotary plate 32 relative to the fixed plate 31, the fixed plate 31 is fixedly mounted on the first mounting frame 2, the rotary plate 32 is fixedly mounted on the second mounting frame 4, and the second mounting frame 4 is fixedly mounted on the seat frame 5. In this manner, the seat frame 5 can be adjusted forward and backward by means of the movement of the slide rail 12 relative to the fixed rail 11; the seat frame 5 can be rotated by the rotation of the rotating disk 32 relative to the fixed disk 31.

As shown in fig. 2, the sliding rail 12 of the sliding rail assembly 1 has a lock pin 121 that can stretch between a high position and a low position, when the lock pin 121 is in the high position of the left figure, the sliding rail 12 is locked with respect to the fixed rail 11, i.e. the sliding rail is in a locked state; when the first mounting bracket 2 presses the lock pin 121 down to be in the lower position of the right drawing, the locking of the sliding rail 12 relative to the fixed rail 11 is released, i.e. the sliding rail is in the unlocked state.

As shown in fig. 3, the first mounting bracket 2 includes a first mounting plate 21, a first mounting leg 22 and a first unlocking lever assembly 23, wherein the first mounting plate 21 is a rectangular plate having a first through hole 211 at the center, four first mounting legs 22 are respectively fixed at four corners below the rectangular plate by screws, for example, to realize the mounting of the first mounting bracket 2 on the sliding rail 12 (see fig. 1), and the first unlocking lever assembly 23 is rotatably mounted below the rectangular plate across the first through hole 211 to cooperate with a lock pin 121 (see fig. 2) of the sliding rail 12 of the sliding rail assembly 1. Specifically, the first unlocking lever assembly 23 includes a first cross bar 231, two pressing levers 232 and a first unlocking lever 233, wherein two ends of the first cross bar 231 are rotatably connected below the first mounting plate 21 through a bushing and a spring, respectively, the two pressing levers 232 are fixedly mounted at two ends of the first cross bar 231 and extend therefrom to act on the locking pins 121 (see fig. 2), and the first unlocking lever 233 is fixedly mounted at the middle of the first cross bar 231 to cooperate with the second mounting frame 4. Therefore, when the first unlocking lever 233 is pressed by the second mounting rack 4 from above, the first cross bar 231 rotates to drive the pressing rods 232 at both sides to press the lock pins 121 (see fig. 2) to unlock the slide rail. In addition, the first unlocking lever assembly 23 further includes first noise-damping catches 234, such as plastic catches, respectively mounted to the free ends of the pressing levers 232 to cooperate with the lock pins 121 (see fig. 2) to damp noise caused by contact with the lock pins 121 (see fig. 2).

As shown in fig. 4, the second mounting bracket 4 includes a second mounting plate 41 and a second lock release lever assembly 42, wherein the second mounting plate 41 is a rectangular plate having a second through hole 411 at the center, four corners above the rectangular plate have four second mounting legs 412 to enable the seat frame 5 to be mounted on the second mounting bracket 4 (see fig. 1), and the second lock release lever assembly 42 is rotatably mounted above the rectangular plate across the second through hole 411 to be engaged with the first lock release lever 233 of the first mounting bracket 2 (see fig. 6). Specifically, the second unlocking lever assembly 42 includes a second cross bar 421, an unlocking handle 422 and a second unlocking lever 423, wherein two ends of the second cross bar 421 are rotatably connected above the second mounting plate 41 through a shaft sleeve and a spring, respectively, the unlocking handle 422 is fixedly mounted at an end of the second cross bar 421 to drive the second cross bar 421 to rotate by an external force, and the second unlocking lever 423 is fixedly mounted at a middle of the second cross bar 421 to act on the first unlocking lever 233 (see fig. 6). Therefore, when the unlocking handle 422 is lifted up by external force, the second cross rod 421 rotates to drive the middle second unlocking rod 423 to press the first unlocking rod 233 downwards, so as to finally realize the unlocking of the sliding rail. In addition, the second unlocking lever assembly 42 further includes a second sound-deadening card 424, such as a plastic clip, mounted to the free end of the second unlocking lever 423 to cooperate with the first unlocking lever 233 (see fig. 6) to cancel frictional noise caused by contact with the first unlocking lever 233 (see fig. 6).

As shown in fig. 5, the second sound-deadening card 424 has a mounting ring 4241, which is fitted over the free end of the second lock-releasing lever 423. Specifically, the second sound-deadening card 424 has a ball structure 4242 therebelow, the spherical bottom surface of which is fitted against the first lock release lever 233. As shown in fig. 6, in the normal seating position of the left drawing, the second unlocking lever 423 is located directly above the first unlocking lever 233, and the ball structure 4242 (see fig. 5) of the second sound-deadening card 424 directly abuts against the free end of the first unlocking lever 233; in the right position after the seat frame 5 rotates 180 degrees backwards, the second unlocking lever 423 is rotated behind the first unlocking lever 233, and the ball structure 4242 (see fig. 5) of the second sound-deadening card 424 is kept abutting against the free end of the first unlocking lever 233, i.e., still kept in contact with the first unlocking lever 233, and at this time, the first unlocking lever 233 can still be pressed downwards to unlock the slide rail by operating the unlocking handle 422. It is apparent that the ball structure 4242 of the second sound-deadening card 424 herein can ensure smooth rotational engagement of the second lock release lever 423 with respect to the first lock release lever 233 during the above-described rotation.

What has been described above is only the preferred embodiment of the present invention, not for limiting the scope of the present invention, but various changes can be made to the above-mentioned embodiment of the present invention.
