Referring to fig. 1 to 4, a linked door opening system includes a cabinet main body 10, two door bodies 20 and a linkage mechanism 30, the two door bodies 20 are disposed at one side of the cabinet main body 10, and opposite sides of the two door bodies 20 are respectively rotatably connected with the cabinet main body 10 through door shafts or hinges (the door shafts and the hinges are not shown in the figures). Wherein, the linkage mechanism 30 includes the transmission assembly 31 and the elastic component 32, the transmission assembly 31 is set to two, and each transmission assembly 31 includes the installation part 311 and the transmission piece 312, the installation part 311 is provided with the first connecting part 313 and the second connecting part 314, the first connecting part 313 and the second connecting part 314 are separated from each other, the first connecting part 313 is rotatably connected with the casing main body 10, the second connecting part 314 is rotatably connected with one end of the transmission piece 312, the other end of the transmission piece 312 is rotatably connected with the door body 20, and the transmission piece 312 is arranged at an interval with the rotation connection of the door body 20 and the rotation connection of the casing main body 10, that is, the installation part 311, the transmission piece 312, the door body 20 and the casing main body 10 are sequentially rotatably connected to form a four-bar linkage. The side edge of each mounting part 311 has a tooth part 315, the tooth parts 315 of the two mounting parts 311 are engaged with each other, at least one elastic member 32 is provided, one end of the elastic member 32 is connected to the mounting part 311, and the other end is connected to the casing main body 10.
When the door needs to be opened, one of the door bodies 20 is rotated relative to the cabinet main body 10, and the other door body 20 is driven to rotate along with the linkage mechanism 30, so that the two door bodies 20 are synchronously rotated and opened. When the door body 20 rotates, the mounting member 311 is driven to rotate, so that the elastic member 32 deforms to store force, and therefore, when the door body 20 is opened, the door body 20 can be opened only by overcoming the acting force of the elastic member 32, so that the door body 20 can be tightly attached to the casing main body 10 when being closed, that is, the linkage mechanism 30 can stably maintain the door body 20 in a closed state, and the use of a user is facilitated. In the above structure, one end of the elastic member 32 is directly connected to the mounting member 311, and it is not necessary to transmit the acting force by providing a transmission structure between the mounting member 311 and the elastic member 32, thereby reducing the kinds and number of components of the link mechanism 30 and simplifying the structure of the link door opening system.
The elastic element 32 is a tension spring, one end of the tension spring is movably connected with the mounting element 311 in a hanging manner, the other end of the tension spring is movably connected with the casing body 10 in a hanging manner, and the door body 20 can stretch and store force when rotating relative to the casing body 10 to be opened.
Fig. 2 is a state diagram showing the door 20 closed with respect to the cabinet main body 10, and fig. 5 is a state diagram showing the door 20 opened with respect to the cabinet main body 10. In some embodiments, when the door body 20 rotates from the state shown in fig. 2 to the state shown in fig. 5, two ends of the elastic member 32 and the first connection portion 313 may be substantially collinear, that is, the first connection portion 313 is located on a longitudinal projection of the elastic member 32, at this time, the linkage mechanism 30 is in a stable state, an acting force of the elastic member 32 on the mounting member 311 does not substantially generate a rotation moment on the mounting member 311, and in combination with a rotation damping of the door body 20 itself, the door body 20 may be relatively stably maintained in an open state, which is convenient for a user to use.
In some embodiments, during the rotation of the door body 20 from the state shown in fig. 2 to the state shown in fig. 5, the distance between the two ends of the elastic member 32 increases and then decreases. That is, during the process of opening the door 20 by rotation relative to the main body 10, the elastic member 32 is stretched and then retracted. When the door body 20 needs to be rotated and closed, the elastic member 32 needs to be stretched and then retracted, so that the door body 20 needs to be rotated and closed by force when the door is closed, and the door body 20 can be stably kept in an open state after being opened, thereby facilitating the use of a user. In addition, when the door body 20 is pushed by a human hand to rotate to open or close the door, the elastic member 32 starts to enter the retraction process through the stretching process, the human hand can be released, and the door body 20 can be driven to continue rotating by the acting force of the elastic member 32 until the door body 20 reaches the door closing state shown in fig. 2 or the door opening state shown in fig. 5, which is convenient for the user to use.
The embodiment of the present invention provides an elastic member 32, which is set to two, and two elastic members 32 are connected to two mounting members 311 in a one-to-one manner, and two elastic members 32 can provide sufficient elastic force to order about the reliable rotation of the door body 20, and to stably and reliably maintain the door body 20 in an open and close state. Wherein, the two elastic members 32 are arranged in a cross manner, which facilitates the installation arrangement on the cabinet main body 10.
In some embodiments, the elastic member 32 may be further provided as one, one end of the elastic member 32 is connected to one of the mounting members 311, and the other end of the elastic member 32 is connected to the cabinet main body 10.
