Detailed implementation manners
[0057] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.
[0058] Please first refer to Figures 1 to 7B As shown, the present utility model is a restoration mechanism 10, including: a first sliding assistance seat 11, a second sliding assistance seat 12, and a synchronizing member 13. The first sliding assistance seat 11 is provided with a first meshing feature 111 and a first elastic structure A, and the first elastic structure A is located on the side of the first terminal E1 of the first meshing feature 111. The second sliding assistance seat 12 is provided with a second meshing feature 121 and a second elastic structure B, and the second elastic structure B is located on the side of the second terminal E2 of the second meshing feature 121. The synchronizing member 13 is arranged between the first meshing feature 111 and the second meshing feature 121.
[0059] Cooperate Figure 2A 、 Figure 2B 、 Figure 5A 、 Figure 5B As shown in Figure 2A , Figure 2B , Figure 5A , and Figure 5B , when the second sliding assist seat 12 slides, a load force F1 is generated. In this embodiment, the first elastic structure A includes: 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 abutting force F2 of the synchronizing member 13, the first arm A1 oscillates to eliminate the load force F1, but not limited thereto.
[0060] Cooperate Figure 2A 、 Figure 2C 、 Figure 6A 、 Figure 6B As shown in Figure 2A , Figure 2C , Figure 6A , and Figure 6B , when the first sliding assist seat 11 slides, a load force F1 is generated. In this embodiment, the second elastic structure B includes: 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 abutting force F2 of the synchronizing member 13, the second arm B1 oscillates to eliminate the load force F1, but not limited thereto.
[0061] Cooperate Figure 2A 、 2D As shown in Figure 2A and 2D , the synchronizing member 13 can be a gear, and the first meshing feature 111 and the second meshing feature 121 can be in the shape of a rack, so that the synchronizing member 13 can be meshed between the first meshing feature 111 and the second meshing feature 121. In this embodiment, the synchronizing member 13 can be installed in a body 131, but not limited thereto.
[0062] As Figure 5A 、 Figure 5B As shown in Figure 5A and Figure 5B , when the synchronizing member 13 is displaced between the first terminal E1 of the first meshing feature 111 and the first stroke segment S1 of the second meshing feature 121, the synchronizing member 13 continuously abuts against the first elastic structure A until the synchronizing member 13 is displaced to the second terminal E2 of the second meshing feature 121 to complete the return. In other words, the return direction of the second sliding assist seat 12 is the first direction D1 for return displacement, but not limited thereto.
[0063] As Figure 6A 、 Figure 6B As shown in Figure 6A and Figure 6B , when the synchronizing member 13 is displaced between the second stroke segment S2 of the first meshing feature 111 and the second terminal E2 of the second meshing feature 121, the synchronizing member 13 continuously abuts against the second elastic structure B until the synchronizing member 13 is displaced to the first terminal E1 of the first meshing feature 111 to complete the return. In other words, the return direction of the first sliding assist seat 11 is the second direction D2 for return displacement, but not limited thereto.
[0064] As Figure 7A 、 Figure 7BAs shown, 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, 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 meshing 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 first elastic structure A or the second elastic structure B can be used alone. The synchronizer 13 is displaced to the first terminal E1 of the first meshing feature 111 by the second elastic structure B to complete the return, thereby eliminating the load force F1 generated by the first slide-assisting seat 11 when sliding. In other words, the first elastic structure A compensates for the uncompleted displacement of the synchronizer 13 in the first stroke segment S1, or the second elastic structure B compensates for the uncompleted displacement of the synchronizer 13 in the second stroke segment 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 return.
[0065] See also Figure 3A , Figure 3B , Figure 3C , Figure 3D and Figure 4 As shown, the utility model is a slide rail 20 assembly with a return mechanism 10, wherein the return mechanism 10 is integrated into the slide rail 20, the slide rail 20 comprises: 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 to assist the movably displacement of the third rail 23 relative to the first rail 21, and the second slide assisting seat 11 is movably arranged between the first rail 21 and the third rail 23 to assist the movably displacement of the third rail 23 relative to the first rail 21. The 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 to this.
[0066] Continuing from the above, at both ends of the first sliding assist seat 11 are provided the first elastic structures A respectively, and at both ends of the second sliding assist seat 12 are provided the second elastic structures B respectively. The first elastic structures A and the second elastic structures B are arranged in a diagonal cross-matching manner, so that whether the slide rail 20 is a left slide rail 20 or a right slide rail 20, the first sliding assist seat 11 and the second sliding assist seat 12 can be used, and it can also be a non-sided design, greatly reducing the cost of the mold.
[0067] Referring again to Figure 1 , Figure 2A , Figure 2E and Figure 3E As shown, on the inner side of the third rail 23 there is a convex body 231. The convex body 231 and the third rail 23 are integrally formed, and the sliding surface 113 of the first sliding assist seat 11 is supported by the convex body 231. Therefore, the convex body 231 is formed on the inner side of the third rail 23, and no accessories are required for assembly between the third rail 23 and the convex body 231, which not only reduces the time for manual assembly but also reduces the cost of assembly parts. Moreover, the third rail 23 is provided with an opening 232, and the opening 232 provides for the installation of the seat body 131, so that the synchronizing member 13 can be fixed on the third rail 23, but this is not limited thereto.
[0068] As Figure 8 shown, a slow return device 30 can also be installed on the first rail 21 of the slide rail 20. The slow return device 30 is provided with a release claw 31, and on the second rail 22 of the slide rail 20 there is a lever 221. When the slide rail 20 is fully extended, the return mechanism 10 performs synchronous return with the first sliding assist seat 11, the second sliding assist seat 12 and the synchronizing member 13. On the basis of this synchronous return, it helps the slide rail 20 to be stably displaced to the release claw 31 for buffer fixation when the slide rail 20 is retracted.
