A two-way split-biased door mechanism as defined in claim 1, wherein, Guide holes are arranged at both sides of the door plate, and pin columns are arranged at one side of the first cavity and one side of the second cavity, so that the pin columns position the door plate when the door plate moves towards or away from the first cavity and the second cavity.

4. A two-way, double-acting, offset door mechanism as defined in claim 1, wherein, The first upper inner guide rail and the first lower inner guide rail are respectively in sliding fit with the upper and lower ends of the door plate; the first upper outer guide rail and the first lower outer guide rail are respectively in sliding fit with the upper and lower ends of the door plate.

5. A two-way, double-acting, offset door mechanism as defined in claim 1, wherein, The bottom end of the door plate is connected with a first sliding assembly, the first sliding assembly comprises a first sliding support, the first sliding support is fixedly connected with the door plate, a vertical pulley and a first horizontal pulley are rotatably connected on the first sliding support.

6. A two-way opposed-bi-fold door mechanism as claimed in claim 5, wherein, The top end of the door plate is connected with a second sliding assembly, the second sliding assembly comprises a second sliding support, a second horizontal pulley is rotatably connected on the second sliding support.

7. A two-way, double-acting, offset door mechanism as defined in claim 1, wherein, The first inner guide rail assembly and the first outer guide rail assembly are connected through a first spring structure, the first driving device drives the first inner guide rail assembly to move towards the direction of approaching or moving away from the first cavity, the first inner guide rail assembly drives the first outer guide rail assembly to move through the first spring structure; The second inner guide rail assembly and the second outer guide rail assembly are connected through a second spring structure, the second driving device drives the second inner guide rail assembly to move towards the direction of approaching or moving away from the second cavity, the second inner guide rail assembly drives the second outer guide rail assembly to move through the second spring structure.
