Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0023] like Figures 1 to 5 As shown, this embodiment discloses a seat side leaning flip adjustment structure, including a base frame 1, a side leaning frame 2, an adjustment switch 3 and a telescopic rod 4, wherein the bottom of the side leaning frame 2 is rotatably connected to the base frame 1, the bottom of the telescopic rod 4 is rotatably mounted on the base frame 1, the top of the telescopic rod 4 extends upward from the inside of the side leaning frame 2 and is fixed inside the side leaning frame 2, the top of the telescopic rod 4 is provided with a contact switch 41 for controlling the telescopic action of the telescopic rod 4, the adjustment switch 3 is mounted on the side leaning frame 2, the adjustment switch 3 is connected to the contact switch 41, and the rotation axis of the side leaning frame 2 connecting the base frame 1 and the rotation axis of the bottom of the telescopic rod 4 connecting the base frame 1 are two non-overlapping parallel lines. When the seat needs to adjust the side lean, it is only necessary to operate the adjustment switch 3 so that the adjustment switch 3 presses the contact switch 41. At this time, the telescopic rod 4 is in the unlocked state. After the side lean frame 2 is turned over by external force and the side lean frame 2 is adjusted to the desired angle, the adjustment switch 3 is released so that the adjustment switch 3 no longer presses the contact switch 41. At this time, the telescopic rod 4 resumes the locked state, and the side lean is locked at the tilt angle state, thereby completing the side lean tilt adjustment. Since the rotation axis connecting the side lean frame 2 with the base frame 1 and the rotation axis connecting the bottom of the telescopic rod 4 with the base frame 1 are two non-overlapping parallel lines, during the side lean tilt adjustment process, the length of the telescopic rod 4 needs to change accordingly, that is, the length of the telescopic rod 4 corresponds to the tilt angle of the side lean frame 2; when the tilt angle of the side lean frame 2 changes, the length of the telescopic rod 4 needs to change accordingly; when the tilt angle of the side lean frame 2 is fixed, the length of the telescopic rod 4 needs to be fixed accordingly; therefore, the change in the length of the telescopic rod 4 can be controlled by the contact switch 41 on the telescopic rod 4, thereby controlling the tilt adjustment of the side lean frame 2. Moreover, the length change of the telescopic rod 4 is not limited by the gear position and has the advantage of stepless adjustment. Therefore, the inclination angle of the side leaning frame 2 can be arbitrarily adjusted within a certain angle range, and the adjustment flexibility is higher. The side leaning can be adjusted to the desired angle and locked to meet different usage scenarios.

[0024] In this embodiment, the telescopic rod 4 is a gas pressure rod. When the contact switch 41 of the telescopic rod 4 is pressed, and there is no external force acting on the telescopic rod 4 or the external force is smaller than the extension force of the telescopic rod 4, the telescopic rod 4 automatically extends; and when the contact switch 41 of the telescopic rod 4 is pressed, and there is an external force acting on the telescopic rod 4, and the external force is larger than the extension force of the telescopic rod 4, the length of the telescopic rod 4 is shortened. When the contact switch 41 of the telescopic rod 4 is not pressed, the telescopic rod 4 is locked in this length state.

[0025] In this embodiment, a protruding structure 21 is provided on the inner side of the side frame 2, and a connecting hole 22 is provided in the protruding structure 21. A protruding section 11 is provided on the base frame 1, and a through hole 12 corresponding to the connecting hole 22 is provided in the protruding section 11. The side frame 2 and the base frame 1 are rotatably connected based on the rotation axis passing through the connecting hole 22 and the through hole 12. A connecting cavity 23 opening inward is provided at the bottom of the side frame 2, and a connecting end 13 for inserting into the connecting cavity 23 is provided at the end of the base frame 1. Limiting plates 24 for limiting the adjustment angle range of the side frame 2 are provided on the left and right sides of the connecting cavity 23. When the side frame 2 is adjusted to the end point of the limited adjustment angle range, the limiting plate 24 on one side contacts the base frame 1, thereby preventing the side frame 2 from over-turning and causing adjustment failure, so that the side frame 2 can be adjusted within an effective range. The outer side of the connecting end 13 is an arc-shaped structure, and the interior of the connecting cavity 23 is provided with an arc-shaped inner cavity adapted to the outer side of the connecting end 13. When the side leaning frame 2 is adjusted to an inclination angle relative to the base frame 1, the connecting end 13 slides along the inner side of the connecting cavity 23, thereby avoiding interference caused by the sliding of the connecting end 13 in the connecting cavity 23.

[0026] In this embodiment, a connecting seat 5 for connecting to the bottom of the telescopic rod 4 is provided inside the outer end of the base frame 1, and a connecting piece 42 is provided at the bottom of the telescopic rod 4, and a first rotating hole 43 is provided on the connecting seat 5; a connecting position 51 for snapping into the connecting piece 42 is provided on the connecting seat 5, and second rotating holes 52 corresponding to the first rotating hole 43 are provided on both sides of the connecting position 51, and a rotational connection is achieved between the connecting seat 5 and the connecting piece 42 based on the rotation axis passing through the second rotating hole 52 and the first rotating hole 43.

[0027] In this embodiment, the adjustment switch 3 includes a pressing plate 31 and a pressing handle 32, one end of the pressing handle 32 is connected to the pressing plate 31, and the other end extends to the upper end of the contact switch 41, the pressing plate 31 or the pressing handle 32 is rotatably connected to the side leaning frame 2, and the pressing plate 31 extends to the outside of the side leaning frame 2. When the side leaning needs to be adjusted in inclination, the pressing plate 31 can be operated to rotate the adjustment switch 3 relative to the side leaning frame 2, and the end of the pressing handle 32 contacts the contact switch 41 at the top of the telescopic rod 4, so that the telescopic rod 4 is in an open state, and the telescopic rod 4 can be extended and retracted under the action of external force, thereby realizing the inclination adjustment of the side leaning frame 2. When the user releases the pressing plate 31, the adjustment switch 3 is automatically reset under the spring action of the contact switch 41. Specifically, a switch seat 6 is also provided in the side support frame 2, and the switch seat 6 includes two clamping plates 61. The two clamping plates 61 are arranged relatively spaced apart to form a mounting position 62 for the telescopic rod 4 to enter and connect. The top of the telescopic rod 4 enters from the bottom of the mounting position 62 and is rotatably connected to the clamping plate 61. The pressing handle 32 enters from the top of the mounting position 62 and is rotatably connected to the clamping plate 61. The bottom end of the pressing plate 31 is provided with a folding plate 33 for pressing the contact switch 41, and the rotatable connection between the pressing handle 32 and the clamping plate 61 is located above the folding plate 33.
