The sliding door unit includes a sliding door, setting on a base through a sliding component, and configured to slide relative to the base when receiving an external force; a first movement mechanism group placed at a first end of the sliding door; and a second movement mechanism group placed at a second end of the sliding door, and the first and second ends being two opposite ends. The first movement mechanism group and the second movement mechanism group move at a matching pace relative to the sliding door on the base when the sliding door is moved by the external force. ## Claims ### Claim 1 A sliding door unit, comprising: a sliding door, setting on a base through a sliding component, and configured to slide relative to the base when receiving an external force; a first movement mechanism group placed at a first end of the sliding door; a second movement mechanism group placed at a second end of the sliding door, and the first and second ends being two opposite ends; and wherein the first movement mechanism group and the second movement mechanism group move at a matching pace relative to the sliding door on the base when the sliding door is moved by the external force and the first movement mechanism group and the second movement mechanism group are of an identical structure and are connected by a connecting rod perpendicular to the sliding direction of the sliding door on the base, and wherein the identical structure comprising a moving block configured to move in a plane perpendicular to the sliding door, a first end of the movement block being hinged to the sliding door, and a second end of the movement block being hinged to the base and being configured to slide with the base in coordination. ### Claim 2 (depends on 1) The sliding door according to claim 1, wherein the first end of the moving block hinges to the sliding door through a sliding shaft, and the second end of the moving block has a U-shaped connecting part with an opening facing the base, and a slidable guiding shaft is located inside a center groove of the U-shaped connecting part in the base. ### Claim 3 (depends on 1) The sliding door according to claim 1, wherein the first end of the connecting rod are fixedly connected to a center hole of the moving block of the first moving mechanism group, and the second end of the connecting rod is fixedly connected to the center hole of the moving block of the second moving mechanism group. ### Claim 4 (depends on 1) The sliding door according to claim 1, wherein a rectangular hole extending along the sliding direction of the sliding door is configured on the base, and the moving block is located in the rectangular hole. ### Claim 5 (depends on 1) The sliding door according to claim 1, wherein the first movement mechanism group and the second movement mechanism group are located at a middle position between two opposite sides of the sliding door. ### Claim 6 (depends on 1) The sliding door according to claim 1, further including a distance-limiting buckle preventing the middle of the sliding door from arching during a sliding motion, wherein one end of the buckle is fixed at a middle position of the sliding door, and the other end of the buckle is slidably hooked on the base. ### Claim 7 (depends on 1) The sliding door according to claim 1, wherein the base is a front panel of a computer chassis. ### Claim 8 An electronic device, including a sliding door unit in front of a chassis with one or more electrical ports, when a sliding door of the sliding door unit slides, the one more electrical ports of the electronic device are revealed, the sliding door unit comprising: a sliding door, setting on a base through a sliding component, and configured to slide relative to the base when receiving an external force; a first movement mechanism group placed at a first end of the sliding door; a second movement mechanism group placed at a second end of the sliding door, and the first and second ends being two opposite ends; a distance-limiting buckle having one end of the buckle being fixed at a middle position of the sliding door and the other end of the buckle slidably hooked on the base, preventing the sliding door from deforming during a sliding motion; and wherein the first movement mechanism group and the second movement mechanism group move at a matching pace relative to the sliding door on the base when the sliding door is moved by the external force. ### Claim 9 (depends on 8) The electronic device according to claim 8, wherein the first movement mechanism group and the second movement mechanism group are connected by a connecting rod, and the connecting rod is perpendicular to the sliding direction of the sliding door on the base. ### Claim 10 (depends on 9) The electronic device according to claim 9, wherein the first movement mechanism group and the second movement mechanism group are of an identical structure, and the structure comprising: a moving block configured to move in a plane perpendicular to the sliding door, a first end of the movement block being hinged to the sliding door, and a second end of the movement block being hinged to the base and being configured to slide with the base in coordination. ### Claim 11 (depends on 10) The electronic device according to claim 10, wherein the first end of the moving block hinges to the sliding door through a sliding shaft, and the second end of the moving block has a U-shaped connecting part with an opening facing the base, and a slidable guiding shaft is located inside a center groove of the U-shaped connecting part in the base. ### Claim 12 (depends on 10) The electronic device according to claim 10, wherein the first end of the connecting rod are fixedly connected to a center hole of the moving block of the first moving mechanism group, and the second end of the connecting rod is fixedly connected to the center hole of the moving block of the second moving mechanism group. ### Claim 13 (depends on 10) The electronic device according to claim 10, wherein a rectangular hole extending along the sliding direction of the sliding door is configured on the base, and the moving block is located in the rectangular hole. ### Claim 14 (depends on 8) The electronic device according to claim 8, wherein the first movement mechanism group and the second movement mechanism group are located at a middle position between two opposite sides of the sliding door. ### Claim 15 (depends on 8) The electronic device according to claim 8, wherein the preventing the sliding door from deforming including preventing the middle section of the sliding door from arching. ### Claim 16 (depends on 8) The electronic device according to claim 8, wherein the base is a front panel of the chassis.
