As shown in FIG. 2A, FIG. 2B, FIG. 5A, and FIG. 5B, the second slide assisting seat 12 also generates a load force F1 when sliding. In this embodiment, the first elastic structure A has a first arm A1 and a first elastic body A2 extending from the first arm A1. When the first elastic body A2 is subjected to the abutment force F2 of the synchronous member 13, the first arm A1 generates vibration to eliminate the load force F1, but the present invention is not limited thereto.

As shown in FIG. 2A, FIG. 2C, FIG. 6A, and FIG. 6B, the first slide assisting seat 11 also generates a load force F1 when sliding. In this embodiment, the second elastic structure B has a second arm B1 and a second elastic body B2 extending from the second arm B1. When the second elastic body B2 is subjected to the abutment force F2 of the synchronous member 13, the second arm B1 generates vibration to eliminate the load force F1, but the present invention is not limited thereto.

As shown in FIGS. 2A and 2D, the synchronizer 13 may be a gear, the first engagement feature 111 and the second engagement feature 121 may be tooth-shaped, so that the synchronizer 13 may be engaged between the first engagement feature 111 and the second engagement feature 121. In this embodiment, the synchronizer 13 may be installed in a seat 131, but is not limited thereto.

As shown in FIG. 5A and FIG. 5B, when the synchronizer 13 is displaced between the first terminal E1 of the first engagement feature 111 and the first travel section S1 of the second engagement feature 121, the synchronizer 13 continues to abut against the first elastic structure A until the synchronizer 13 is displaced to the second terminal E2 of the second engagement feature 121 to complete the return. In other words, the return direction of the second slide-assisting seat 12 is the first direction D1 for return displacement, but is not limited thereto.

As shown in FIG. 6A and FIG. 6B, when the synchronizer 13 is displaced between the second stroke section S2 of the first engagement feature 111 and the second terminal E2 of the second engagement feature 121, the synchronizer 13 continues to abut against the second elastic structure B until the synchronizer 13 is displaced to the first terminal E1 of the first engagement feature 111 to complete the return. In other words, the return direction of the first slide-assisting seat 11 is the second direction D2 for return displacement, but the present invention is not limited thereto.

As shown in FIG. 7A and FIG. 7B, the first slide-assisting seat 11, the first elastic structure A, the second slide-assisting seat 12, the synchronous member 13, or the first slide-assisting seat 11, the second slide-assisting seat 12, the second elastic structure B, and the synchronous member 13 can be two types of return mechanisms 10, so the first elastic structure A or the second elastic structure B can be used alone, and the first elastic structure A and the second elastic structure B can also cooperate with each other. When the synchronous member 13 moves to the second terminal E2 of the second engagement feature 121 with the first elastic structure A to complete the return, the load force F1 generated by the second slide-assisting seat 12 when sliding can be eliminated. , or the synchronizer 13 is displaced to the first end E1 of the first engagement feature 111 by the second elastic structure B to complete the reversion, so that the load force F1 generated by the first slide-assisting seat 11 during sliding can be eliminated. In other words, the first elastic structure A compensates for the uncompleted displacement of the synchronizer 13 in the first stroke section S1, or the second elastic structure B compensates for the uncompleted displacement of the synchronizer 13 in the second stroke section S2. In this way, the first elastic structure A and the second elastic structure B are complementary, so that the displacement stroke of the synchronizer 13 between the first slide-assisting seat 11 and the second slide-assisting seat 12 can complete the synchronous reversion.

Referring to FIG. 3A, FIG. 3B, FIG. 3C, FIG. 3D and FIG. 4, the present invention is a slide rail assembly having a reciprocating mechanism 10, wherein the reciprocating mechanism 10 is integrated into the slide rail 20, the slide rail 20 includes a first rail 21, a second rail 22 and a third rail 23, the second rail 22 can be movably displaced relative to the first rail 21, and the third rail 23 is installed between the first rail 21 and the second rail 22, the first slide assisting seat 11 is movably arranged between the first rail 21 and the third rail 23, and is used to assist the third rail 23 to move relative to the first rail 21. 1, the second slide-assisting seat 12 is movably arranged between the third rail 23 and the second rail 22 to assist the movable displacement of the second rail 22 relative to the third rail 23. In this embodiment, the first slide-assisting seat 11 includes at least one first rolling body 112, and the first rolling body 112 is used to assist the movable displacement of the third rail 23 relative to the first rail 21; the second slide-assisting seat 12 includes at least one second rolling body 122, and the second rolling body 122 is used to assist the movable displacement of the second rail 22 relative to the third rail 23, but is not limited thereto.

As mentioned above, the first elastic structure A is provided at both ends of the first slide-assisting seat 11, and the second elastic structure B is provided at both ends of the second slide-assisting seat 12. The first elastic structure A and the second elastic structure B are cross-matched diagonally, so that the first slide-assisting seat 11 and the second slide-assisting seat 12 can be used regardless of whether the slide rail 20 is a left slide rail or a right slide rail, and can also be a non-edge design, which greatly reduces the cost of the mold.

Referring to Figures 1, 2A, 2E and 3E, the inner side of the third rail 23 has a protrusion 231, which is integrally formed with the third rail 23 and supports the sliding surface 113 of the first slide-assisting seat 11 with the protrusion 231. Therefore, the protrusion 231 is formed on the inner side of the third rail 23, and no accessories are required between the third rail 23 and the protrusion 231 for assembly, which not only reduces the time for manual assembly, but also reduces the cost of assembling parts. In addition, the third rail 23 is provided with an opening 232, which provides the seat 131 for installation, so that the synchronizer 13 can be fixed on the third rail 23, but it is not limited thereto.

As shown in FIG8 , a buffer 30 can also be installed on the first rail 21 of the slide rail 20. The buffer 30 is provided with a release claw 31, and a lever 221 is provided on the second rail 22 of the slide rail 20. When the slide rail 20 is fully extended, the return mechanism 10 performs synchronous return with the first auxiliary slide seat 11, the second auxiliary slide seat 12 and the synchronous member 13. On the basis of the synchronous return, it helps the slide rail 20 to be stably positioned and moved to the release claw 31 for buffering and fixing when the slide rail 20 is retracted.
