[0028] Embodiment 1
[0029] As Figures 1 to 3 shown, the present utility model provides a slide rail structure, including a pair of first slide rails 1, a pair of second slide rails 2, a support bottom plate 3, and at least one connection bracket 4. The first slide rail 1 includes a first guide rail 11 and a first sliding part 12. The second slide rail 2 includes a second sliding part 21. The support bottom plate 3 is fixed on the second sliding part 21. The first guide rail 11 is fixed on the support bottom plate 3. The first sliding part 12 slides along the first guide rail 11. One end of the connection bracket 4 is fixedly connected to the first sliding part 12, and the other end of the connection bracket 4 partially wraps the support bottom plate 3.
[0030] As Figure 6 、 Figure 7As shown in the figure, the support base plate 3 includes a main body portion 31 and an extension portion 32. The two ends of the main body portion 31 are respectively connected to a pair of second sliding rails 2. The extension portion 32 extends from one end of the main body portion 31 along the length direction of the second sliding portion 21, and the extension portion 32 is fixed on the second sliding portion 21. A limiting groove 321 that cooperates with the second sliding portion 21 is provided on the extension portion 32, and the second sliding portion 21 is clamped in the limiting groove 321. The support base plate 3 of this embodiment is in a "C" shape. The first sliding rail 1 can be the side-sliding rail (i.e., the left and right rail) of the seat, and the second sliding rail 2 can be the front-back rail of the seat. The support base plate 3 is fixedly connected to the second sliding portion 21 of the second sliding rail 2. The support base plate 3 can be fixed at the front end or the rear end of the second sliding rail 2. Correspondingly, the first guide rail 11 at the front end or the rear end is fixed on the support base plate 3. The two ends of the first guide rail 11 that are not fixed on the support base plate 3 are directly fixed to the corresponding second sliding portion 21 by bolts, and the first sliding portion 12 corresponding to the first guide rail 11 is directly fixed to the seat frame fixing bracket 51 of the seat frame 5 by bolts.
[0031] As Figures 4 to 7As shown in the figure, the connecting bracket 4 includes a fixing part 41 and a bending part 42. The fixing part 41 is fixed on the first sliding part 12. One end of the fixing part 41 bends towards the main body part 31 to form the bending part 42. The bending part 42 partially covers the support bottom plate 3. By covering the support bottom plate 3 with the bending part 42, the limit between the connecting bracket 4 and the support bottom plate can be realized. One end of the bending part 42 is formed with a first limiting flange 421, and the other end of the main body part 31 is formed with a second limiting flange 311. The first limiting flange 421 and the second limiting flange 311 cooperate for limiting. The bending part 42 partially covers the support bottom plate 3 through the cooperation of the first limiting flange 421 and the second limiting flange 311. In this embodiment, there are two connecting brackets 4, and the two connecting brackets 4 are respectively fixed on the left and right sides of the first sliding part 12 at the front end or the rear end. The fixing part 41 of each connecting bracket 4 is attached to the bottom surface of the seat frame fixing bracket 51 of the seat frame 5 and fixed on the seat frame fixing bracket 51 of the seat frame 5 and the first sliding part 12 with two bolts. The fixing part 41 first bends obliquely downward and away from the first sliding rail 12, and then bends downward towards the main body part 31 to form the bending part 42. The bending part 42 bends arcuately upward and towards the first sliding rail 12 to form the first limiting flange 421. Such a structure of the connecting bracket 4 can realize the elastic buffering of the seat and improve the anti-deformation ability of the seat; one end of the main body part 31 first bends upward to form an upward turning part 312, and the upward turning part 312 then bends arcuately downward to form the second limiting flange 311. A guiding groove 313 extending in the left-right direction of the vehicle is formed between the second limiting flange 311 and the upward turning part 312. The first limiting flange 421 is arranged in the guiding groove 313. When the seat slides sideways, the first limiting flange 421 moves along the guiding groove 313. When the seat is impacted, the cooperation and limitation of the first limiting flange 421 and the second limiting flange 311 can limit the seat and improve the safety performance of the seat.
[0032] A number of weight-reducing holes 6 are provided on both the support bottom plate 3 and the connecting bracket 4. Specifically, in this embodiment, two weight-reducing holes 6 are provided on each of the support bottom plate 3 and each connecting bracket 4. The weight-reducing holes 6 of the support bottom plate 3 are located on the left and right sides of the main body part 31, and the weight-reducing holes 6 of the connecting bracket 4 are located on the left and right sides of the connection between the fixing part 41 and the bending part 42. The setting of the weight-reducing holes 6 can realize the light weight of the sliding rail structure.
[0033] A first cross-bridge motor 7 is connected between the first sliding parts 12 of the pair of first sliding rails 1. The first cross-bridge motor 7 drives the first sliding parts 12 to slide along the first guide rail 11. A second cross-bridge motor 8 is connected between the second sliding parts 21 of the pair of second sliding rails 2. The second sliding rail 2 further includes a second guide rail 22. The second cross-bridge motor 8 drives the second sliding parts 21 to slide along the second guide rail 22. Both ends of the first cross-bridge motor 7 are respectively connected to the pair of first sliding rails 1, and both ends of the second cross-bridge motor 8 are respectively connected to the pair of second sliding rails 2. In this embodiment, the first sliding rail 1 can be used as the side-sliding rail of the seat, and the second sliding rail 2 can be used as the front-back sliding rail of the seat. The cross-sections of both the first sliding rail and the second sliding rail are in an M shape. Flanges that cooperate with each other are formed on both the first sliding part 12 and the first guide rail, and flanges that cooperate with each other are also formed on both the second sliding part 21 and the second guide rail 22. The flanges can guide and limit the position of the first sliding part 12 or the second sliding part 21 when sliding.
[0034] When assembling the present utility model, first, the support bottom plate 3 is fixed on the second sliding part 21, and then the first guide rail 11 of one of the first sliding rails 1 and / or the first guide rail 11 of the other first sliding rail 1 is fixed on the support bottom plate 3. If only one first guide rail 11 is fixed on the support bottom plate 3, then the other first guide rail 11 is fixed on the second sliding part 21. Then, the connection bracket 4 is pre-assembled on the support bottom plate 3 and the first sliding part 12 through the cooperation of the first limiting flange 421 and the second limiting flange 311. Then, the first sliding part 12 corresponding to the first guide rail 11 fixed on the support bottom plate 3 is fixedly connected to the seat frame fixing bracket 51 of the seat through the connection bracket 4, and the first guide rail 11 fixed on the second sliding part 21 is directly fixedly connected to the seat frame fixing bracket 51 of the seat frame 5. After assembly, the first sliding rail 1 can be the side-sliding rail of the seat, and the second sliding rail 2 can be the front-back sliding rail of the seat. When the seat slides sideways, the seat frame 5 and the connection bracket 4 of the seat slide left and right along the first guide rail 11 with the first sliding part 12. When the seat slides back and forth, the seat frame 5, the connection bracket 4, the first sliding rail 1 and the support bottom plate 3 of the seat slide back and forth with the second sliding part 21. By setting the support bottom plate 3 in the present utility model, the connection strength between the pair of second sliding parts 21 and the connection strength between the first sliding part 12 and the second sliding part 21 can be effectively improved. By setting the connection bracket 4, the connection strength of the second sliding part 21 can be further improved, thereby effectively improving the stiffness and strength of the sliding rail structure, reducing the jitter and abnormal noise during the sliding of the sliding rail, and improving the NVH performance. It should be noted that in addition to connecting the seat, the connection bracket 4 of the present utility model can also connect other devices that need to achieve sliding, and the present utility model does not make special limitations on this.

[0037] In this embodiment, a third limiting flange 411 is formed at one end of the connection bracket 4 fixedly connected to the first sliding part 12, and the third limiting flange 411 cooperates with the seat frame fixing bracket 51 for limiting. The third limiting flange 411 is formed at one end of the fixing part 41 away from the bending part 42.
