Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-7As shown, a seat slide rail for commercial passenger vehicles includes two main rails 1 and a connecting frame 2, the connecting frame 2 is used to connect with the bottom of the seat, the main rail 1 is used to limit the horizontal position of the seat, the right side of the left main rail 1 is connected with an arc-shaped rail 11, the arc-shaped rail 11 is used to limit the rotation of the seat, the outer side wall of the arc-shaped rail 11 is connected with the right main rail 1, the right side of the right main rail 1 is connected with an arc-shaped rail 2 12, the bottom of the connecting frame 2 is located at two corners and is fixedly connected to the limiting seat 22, the bottom of the connecting frame 2 is located at the other two corners and is fixedly connected to the vertical rod 21, and the inner side wall of the left main rail 1 is slidably connected with a limiting seat 22 The card plate 13 for limiting is provided with a limiting mechanism 3 for regulating the card plate 13 on the right side wall of the left main rail 1. The bottom of the left vertical rod 21 is rotatably connected to the limiting plate 25. The bottom of the limiting plate 25 is fixedly connected with a slider 26. The slider 26 is slidably connected to the inside of the main rail 1. The bottom of the slider 26 is rotatably connected with a plurality of rollers 261. The bottom of the right vertical rod 21 is movably embedded with a steel ball 211. The limiting plate 25 connects the slider 26 and the vertical rod 21. The slider 26 is used to limit the vertical rod 21. The rollers 261 and the steel balls 211 are both used to reduce friction during contact. The bottoms of the two limiting seats 22 are both rotatably connected with The circular plate 23 is rotatably connected to a roller 24 at the bottom of the circular plate 23. The rotational connection between the limit seat 22 and the circular plate 23 enables the limit seat 22 to adapt to the movement inside the main rail 1 and the sliding inside the arc rail 11, so that the roller 24 can automatically adjust the direction of movement. A plurality of slots 15 are evenly spaced on the inner bottom surface of the left main rail 1. The inner sliding connection of the limit plate 25 is connected to a slider 27. A spring 291 is fixedly connected between one end of the slider 27 and the limit plate 25. An electric push rod 28 is fixedly sleeved inside the slider 27. An insert block 29 is fixedly sleeved at the output end of the electric push rod 28. The insert block 29 is movable with the adjacent slot 15. When the card plate 13 is in the limited state, the limit seat 22 inside the left main rail 1 can only move horizontally but cannot move into the arc rail 11. With the limit of the slider 1 26, the connecting frame 2 can only move vertically as a whole. After moving to the specified position, the electric push rod 1 28 can be started to insert the plug block 29 into the adjacent card slot 15 to limit the connecting frame 2. The plug block 29 may not be directly aligned with the card slot 15. The sliding of the slider 2 27 and the limit plate 25 provides adjustment space for the plug block 29 to prevent motion interference and damage to the electric push rod 1 28. The adjacent ends of the two main rails 1 are fixedly connected with a mounting plate 14 for mounting and fixing the two main rails 1.
[0025] The limiting mechanism 3 includes an electric push rod 2 31 fixedly connected to the right side wall of the left main rail 1, and a connecting plate 32 is fixedly sleeved on the output end of the electric push rod 2 31. The front end of the connecting plate 32 passes through the main rail 1 and is fixedly connected to the card plate 13. When it is necessary to release the limit of the limiting seat 22, the electric push rod 2 31 can be started to drive the connecting plate 32 to move, thereby driving the card plate 13 to move, and releasing the blocking of the limiting seat 22. At this time, the seat can be rotated with the left vertical rod 21 as the center of the circle, and the two limiting seats 22 are moved to the inside of the arc track 11, so as to adjust the direction of the seat. For adjustment, a slider three 33 is slidably connected to the right side wall of the left main rail 1, a round rod 34 is fixedly connected to one side of the slider three 33, the round rod 34 passes through the main rail 1 and is slidably connected thereto, a spring two 35 is fixedly connected between one end of the round rod 34 and the main rail 1, the spring two 35 can prevent the round rod 34 and the slider three 33 from being separated from the main rail 1, when the connecting plate 32 drives the card plate 13 to move, the rear end of the connecting plate 32 contacts with the slider three 33 and moves the slider three 33 to the inside of the main rail 1, which can block the slider one 26, so that the seat as a whole cannot move horizontally but can only rotate.
[0026] By connecting the arc rail 1 11 and the arc rail 2 12 on the right sides of the two main rails 1 respectively, the electric push rod 2 31 can be started to move the clamping plate 13 away, and at the same time the connecting plate 32 moves the slider 3 33 to clamp the slider 1 26 so that the seat cannot move horizontally. At this time, the seat can be rotated 90 degrees without installing a turntable separately, and the installation is relatively convenient. The roller 1 24 and the roller 2 261 are in rolling contact with the arc rail 1 11, and the seat can be rotated more smoothly without frequent maintenance. It is convenient to rotate the two front seats to a relative state, so that the people in the front row can see each other with the people in the back row, and the communication is more sufficient, which is convenient to use.
[0027] In the initial state, the card plate 13 is in a limited position state, and the limit seat 22 inside the left main rail 1 can only move horizontally but cannot move into the arc-shaped rail 11. With the limit of the slider 1 26, the connecting frame 2 can only move vertically as a whole, and the seat can be moved forward and backward. After the adjustment is completed, the electric push rod 1 28 can be started to insert the plug 29 into the adjacent card slot 15 to limit the connecting frame 2. The plug 29 may not be directly aligned with the card slot 15. The sliding of the slider 27 and the limit plate 25 provides adjustment space for the plug 29, and the seat position is fixed by the card connection between the plug 29 and the card slot 15.
[0028] When the seat needs to be rotated, first move the insert block 29 out of the slot 15, move the seat to the front end of the main rail 1, start the electric push rod 2 31 to drive the connecting plate 32 to move, thereby driving the card plate 13 to move, and removing the obstruction of the limit seat 22. The rear end of the connecting plate 32 contacts the slider 33 and moves the slider 33 to the inside of the main rail 1. The slider 1 26 can be limited so that the seat as a whole cannot move horizontally but can only rotate. At this time, the seat can be rotated with the vertical rod 21 on the left as the center of the circle, and the two limit seats 22 are moved to the inside of the arc track 11, so that the seat is rotated 90 degrees. When installing two seats in the same row of the RV, the two sets of slide rails need to be installed symmetrically.
