The first sliding rail 10 is provided with a first sliding groove 11 along the length direction of the first sliding rail 10, the length of the first sliding groove 11 is the same as that of the first sliding rail 10, the second sliding rail 20 is arranged in the first sliding groove 11 and can slide relative to the first sliding rail 10, the front end or the rear end of the second sliding rail 20 can slide outside the first sliding rail 10, the second sliding rail 20 is provided with a second sliding groove 21, the first elastic support 30 is arranged in the first sliding groove 11 of the first sliding rail 10, two ends of the first elastic support 30 are respectively connected with the inner wall of the first sliding groove 11, the second elastic support 40 is arranged in the second sliding groove 21 of the second sliding rail 20, and two ends of the second elastic support 40 are respectively connected with the inner wall of the second sliding groove 21; the two first elastic brackets 30 are respectively disposed at two ends of the first sliding rail 10, and the two second elastic brackets 40 are respectively disposed at two ends of the second sliding rail 20. Through the inner wall of connecting first spout 11 with the both ends of first elastic support 30, the inner wall of second spout 21 is connected to second elastic support 40, and when first slide rail 10 received the open force, first elastic support 30 restriction first slide rail 10 opened, and when second slide rail 20 received the power of drawing together, second elastic support 40 restriction second slide rail 20 was drawn together, in this way, can guarantee the stable in structure of first slide rail 10 and second slide rail 20 and car seat's security.
It should be understood that, when the second slide rail 20 of the seat is adjusted to the position that the front end portion of the second slide rail 20 is located in the first slide groove 11, and the rear end portion of the second slide rail 20 is located outside the first slide groove 11, in a frontal collision, under the downward extrusion action of the second slide rail 20, a more serious opening phenomenon occurs at the front end of the first slide rail 10; when the front end of the second slide rail 20 of the seat moves forward away from the front end of the first slide groove 11, the rear end of the second slide rail 20 is often severely gathered. This can exacerbate the sinking of the occupant to a certain extent, thereby severely affecting the normal functioning of the restraint system and causing serious injury to the occupant.
In an embodiment, the first elastic support 30 and the second elastic support 40 each include a first connecting piece 31, a first energy absorbing member 32, a limiting member 33, a second energy absorbing member 34 and a second connecting piece 35, the first connecting piece 31 and the second connecting piece 35 play a role in connecting each component, the first connecting piece 31 and the second connecting piece 35 are disposed on two sides of the limiting member 33, two ends of the first energy absorbing member 32 are respectively connected with the first connecting piece 31 and the limiting member 33, and two ends of the second energy absorbing member 34 are respectively connected with the limiting member 33 and the second connecting piece 35. The first and second connection members 31 and 35 are welded to the first or second slide rails 10 and 20, so that the first and second elastic supports 30 and 40 can be stably mounted. It should be appreciated that the first and second elastic supports 30 and 40 are substantially identical and the first and second energy absorbing members 32 and 34 are substantially identical.
Further, the limiting member 33 includes a central plate 331 and limiting plates 332 disposed on two sides of the central plate 331, the first connecting piece 31 is a first connecting block, the second connecting piece 35 is a second connecting block, the first energy absorbing member 32 and the second energy absorbing member 34 are elastic connecting pieces, that is, the first energy absorbing member 32 and the second energy absorbing member 34 can deform when being stressed, and when the elastic connecting pieces compress, the first connecting block and the second connecting block can abut against the limiting plates 332. The first energy absorbing member 32 and the second energy absorbing member 34 can provide a buffering force when the second sliding rail 20 is folded or the first sliding rail 10 is unfolded, and the limiting plate 332 can reduce the deformation of the second sliding rail 20 when the folding phenomenon occurs, so that the structural stability of the second sliding rail 20 can be protected.
In one embodiment, the elastic connection member is a plurality of bending rods 321 disposed at two sides of the limiting plate 332, and the plurality of bending rods 321 are connected in a tail-to-tail manner. The bending rods 321 are elastically arranged, gaps are reserved among the bending rods 321, when the first sliding rail 10 is opened, the elastic connecting pieces are stressed, the gaps among the bending rods 321 can be enlarged, when the second sliding rail 20 is closed, the elastic connecting pieces are stressed, the gaps among the bending rods 321 can be reduced, and it is required to understand that the length of the bending rods 321 from the connecting position with the central plate 331 to the connecting position with the first connecting block or the second connecting block is larger than that of the limiting plate 332, so that the bending rods 321 have a certain buffer space. In order to make the stress of the bent rods 321 at both sides of the limiting plate 332 more uniform, the bent rods 321 at both sides of the limiting plate 332 are provided with the same number. The bottom of the bent rod 321 is also provided with a supporting rod 322, the supporting rod 322 can be abutted against the bottom of the first sliding rail 10 under the driving of the bent rod 321, and the supporting rod 322 plays a role in supporting the bent rod 321.
In other embodiments, the elastic connection member may be a spring, and the spring is sleeved on the limiting plate 332. Buffering of the first slide rail 10 or the second slide rail 20 is achieved by expansion and contraction of the springs, and it should be understood that the length of the springs is greater than the length of the limiting plates 332.
In order that the second slide rail 20 does not interfere with the first elastic support 30 when sliding in the first slide rail 10, the second elastic support 40 is located below the second slide rail 20. In this way, the connection of the first slide rail 10 and the second slide rail 20 is made more reasonable.
Specifically, the two sides of the second sliding rail 20 are bent outwards to form a first bending section 12, the two sides of the first sliding rail 10 are bent inwards to form a second bending section 22, and the first bending section 12 and the second bending section 22 can be embedded into each other. By embedding the first and second bent sections 12, 22 in each other, the first and second slide rails 10, 20 are allowed to move relative to each other, and the second slide rail 20 is allowed to move on the first slide rail 10 since the first slide rail 10 is fixed to the vehicle body and the second slide rail 20 is fixed to the seat bottom at the time of installation. The first sliding groove 11 is communicated with the second sliding groove 21, namely, the second sliding rail 20 is opposite to the first sliding rail 10.
The second aspect of the utility model also provides an automobile seat comprising an anti-splay and gathering mechanism of an automobile seat slide rail as defined in any one of the above. The automobile seat has the corresponding technical effect because the automobile seat slide rail opening-preventing and closing-preventing mechanism is used.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
