Embodiment 1

[0042] The present invention discloses a synchronous sliding mechanism 1, as shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4. The synchronous sliding mechanism 1 comprises a guide rail 12 and a first connecting rod mechanism 13, wherein the first connecting rod mechanism 13 comprises a fixed base 134, and a first connecting rod 131 and a second connecting rod 132 which are symmetrical in a horizontal central axial direction of the fixed base 134; ends of the first connecting rod 131 and the second connecting rod 132 on a same side are pivotally connected to the fixed base 134; sliding ends 133 corresponding to the guide rail 12 are provided at the other ends of the first connecting rod 131 and the second connecting rod 132; and when the guide rail 12 reciprocates in a horizontal axial direction, the sliding ends 133 of the first connecting rod 131 and the second connecting rod 132 are close to or far away from each other.

[0043] Preferably, the first connecting rod 131 and the second connecting rod 132 are pivotally connected to the fixed base 134 through a pivotal connection piece or pivotally connected to the fixed base 134 respectively. In the embodiment, the first connecting rod 131 and the second connecting rod 132 are pivotally connected to the fixed base 134 respectively. In this way, when the guide rail 12 is far away from the fixed base 134, the sliding ends 133 of the first connecting rod 131 and the second connecting rod 132 in the guide rail 12 are gradually close to each other; and when the guide rail 12 is close to the fixed base 134, the sliding ends 133 of the first connecting rod 131 and the second connecting rod 132 in the guide rail 12 are gradually away from each other. Due to the symmetrical design of the first connecting rod 131 and the second connecting rod 132, the sliding ends 133 move in the guide rail more synchronously.

Embodiment 2

[0044] Based on the embodiment 1, the synchronous sliding mechanism 1 provided by the embodiment 2 is shown in FIG. 2 and further comprises a second connecting rod mechanism 14, wherein the second connecting rod mechanism 14 comprises a sliding base 141, and a third connecting rod 143 and a fourth connecting rod 144 which are symmetrically provided in the horizontal central axial direction of the fixed base 134; the sliding base 141 and the fixed base 134 are located on a same side of the guide rail 12; and ends of the third connecting rod 143 and the fourth connecting rod 144 on a same side are pivotally connected to the sliding base 141, and another end of the third connecting rod 143 is pivotally connected to the first connecting rod 131 and the other end of the fourth connecting rod 144 is pivotally connected to the second connecting rod 132.

[0045] As shown in FIG. 3 and FIG. 4, the synchronous sliding mechanism 1 is further provided with a horizontal shaft 11 with a sliding groove 111 in a horizontal direction, one end of the horizontal shaft 11 is fixed on the fixed base 134 and the other end of the horizontal shaft 11 is slidingly matched with the sliding base 141, and the sliding base is provided with a sliding piece corresponding to the sliding groove 111. Preferably, the sliding piece used in the embodiment is a pulley, and the pulley cooperates with the sliding groove 111, so that the third connecting rod 143 and the fourth connecting rod 144 may slide smoothly along the horizontal shaft 11 in the horizontal direction. When the guide rail 12 moves, the sliding ends 133 of the first connecting rod 131 and the second connecting rod 132 slide along the guide rail 12 in a vertical direction, the third connecting rod 143 and the fourth connecting rod 144 slide along the horizontal shaft 11 in the horizontal direction, a quadrilateral structure formed by the first connecting rod mechanism 13 and the second connecting rod mechanism 14 enables the whole mechanism to operate smoothly and stably, and the multi-rod linkage of the first connecting rod 131, the second connecting rod 132, the third connecting rod 143 and the fourth connecting rod 144 enables the operation process of the whole mechanism to be more synchronous.

[0046] The third connecting rod 143 and the fourth connecting rod 144 are provided with bending portions 142. Taking the third connecting rod 143 as an example, the bending portion 142 divides the third connecting rod 143 into a front rod portion 145 and a rear rod portion 146 which are located in different planes. More preferably, the front rod portion 145 and the rear rod portion 146 of the third connecting rod 143 are parallel with each other, and the front rod portion 145 is located on an inner side of the rear rod portion 146 in a depth direction. Due to the presence of the bending portions 142, the third connecting rod 143 and the fourth connecting rod 144 are staggered in the depth direction. Meanwhile, rear parts of the third connecting rod 143 and the fourth connecting rod 144 are pivotally connected to the sliding base 141, so that the pulley on the sliding base 141 is more matched with the sliding groove 111 in the horizontal shaft 11. In the process that the sliding base 141 slides along the horizontal shaft 11, there is no deviation in the depth direction, and the sliding process is more stable.

Specifically, the guide rail 12 is provided with a hinged piece, and the door plate 21 is hinged with the guide rail 12. The door plate 21 is opened and closed through the hinged piece. Meanwhile, when the door plate 21 is parallel with the guide rail 12, by pushing and pulling the door plate 21, the expansion and retraction of the door plate 21 may be realized through the expansion and retraction of the synchronous sliding mechanism 1. The telescopic door is widely applied and can obviously reduce the space occupied by the door body.
