[0038] In one embodiment, the moving block 131 includes an active block 1311 and a driven block 1312, the elastic member 132 is connected to the driven block 1312, and the moving slide rail 120 is provided with a first slide groove 121 arranged along the extension direction, the driven block 1312 is at least partially inserted into the first slide groove 121 and is configured to be able to slide along the first slide groove 121, the active block 1311 is at least partially protruded from the driven block 1312 and the fixed slide rail 110 is located on the moving path of the active block 1311, so that when the moving slide rail 120 moves from the open position to the closed position, the active block 1311 can abut against the fixed slide rail 110.

[0039] In one embodiment, an open groove 111 is formed at one end of the fixed slide rail 110 toward the active block 1311. When the movable block 131 and the fixed slide rail 110 are in contact with each other, the active block 1311 is at least partially embedded in the groove 111 to achieve a locking engagement when the movable block 131 and the fixed slide rail 110 are in contact with each other.

Figures 4 to 6 As shown, the front stopper 124 is located at one end of the slide rail portion 125 and is partially embedded in the slide groove 1251 .

[0045] like Figure 5 and Figure 6 As shown, in one embodiment, the movable slide rail 120 is provided with a front buffer pad 126, and one end of the fixed slide rail 110 facing the buffer assembly 130 is located on the moving path of the front buffer pad 126, and when the movable slide rail 120 is in the closed position, the fixed slide rail 110 abuts against the front buffer pad 126 to avoid vibration or sound caused by the abutment.

[0046] like Figure 4 As shown, in one embodiment, the movable slide rail 120 is provided with a rear buffer pad 127, and the end of the fixed slide rail 110 away from the buffer assembly 130 is located on the moving path of the rear buffer pad 127, and when the movable slide rail 120 is in the open position, the fixed slide rail 110 abuts against the rear buffer pad 127 to avoid vibration or sound caused by the abutment.

[0047] like Figure 7 As shown, in one embodiment, the sliding guide rail 100 also includes a rolling assembly 140, the fixed slide rail 110 includes a fixed track surface 112, the movable slide rail 120 is provided with a movable guide surface 128 arranged opposite to the fixed track surface 112, and the rolling assembly 140 is located between the fixed track surface 112 and the movable guide surface 128 and is rollingly connected to the fixed track surface 112 and the movable guide surface 128 to reduce the friction between the movable slide rail 120 and the fixed slide rail 110.

[0048] like Figure 7 As shown, in one embodiment, the rolling assembly 140 includes a retainer 141 and a ball 142. The retainer 141 is located between the fixed track surface 112 and the movable guide surface 128, and the retainer 141 is provided with a plurality of openings 1411 for placing the ball 142. The ball 142 is assembled in the openings 1411, and the position of the ball 142 is limited by the retainer 141, so that the ball 142 and the retainer are integrated as a whole, so that the rolling is smoother.

Preferably, there is a gap between the roller, the fixed track surface 112 and the movable guide surface 128 to accommodate installation errors and part size errors.

[0049] When the sliding guide rail 100 in the above scheme is in use, when the storage member 300 is moved outwardly, the storage member 300 moves relative to the sliding guide rail 100 under the action of the roller 420. After moving a certain distance, under the action of the front stop block 124, the movable slide rail 120 moves from the closed position toward the open position along with the storage member 300, and when the movable slide rail 120 is in the open position, the elastic member 132 pushes the active block 1311 to move from the second slide groove 122 toward the limiting groove 123, and under the guidance of the inclined groove 111, the active block 1311 enters the limiting groove 123.

When it moves to the point where the movable block 131 abuts against the fixed slide rail 110, the active block 1311 located in the limiting groove 123 is facing the opening of the groove 111, and as the movement continues, the portion of the active block 1311 embedded in the groove 111 increases. The groove 111 can drive the active block 1311 located in the limiting groove 123 to move toward the second slide groove 122 and along the second slide groove 122 until the movable slide rail 120 is in the closed position, at which time the fixed slide rail 110 abuts against the front buffer pad 126.

[0051] The above-mentioned sliding guide rail 100 is provided with an elastic member 132 respectively connected to the movable slide rail 120 and the movable block 131, and is configured so that when the movable slide rail 120 moves toward the closed position, the movable block 131 and the fixed slide rail 110 can be interlocked and move synchronously, so that the elastic member 132 acting on the movable slide rail 120 and the movable block 131 can apply a pulling force to the movable slide rail 120 and the fixed slide rail 110, so that the elastic member 132 drives the movable slide rail 120 and the fixed slide rail 110 to be closer, and then provides a force for the movable slide rail 120 to move toward the closed position, so that the elastic member 132 can assist in the process of closing the storage member 300, thereby improving the experience of closing the storage member 300.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
