摘要： A folding apparatus and an electronic device are disclosed. The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state. Therefore, when the electronic device is unfolded from the folded state to the flattened state, layered misalignment of the flexible display can be reduced, and crease recovery of the flexible display can be accelerated, thereby improving a flattening effect of the flexible display.

The folding apparatus (100) includes a first housing (10), a rotation mechanism (20) and a second housing (30). The rotation mechanism (20) includes a middle housing (1), a first support (2) and a second support (3), one end of the first support (2) is rotatably connected to the middle housing (1), and the other end is fixedly connected to the first housing (10). A support surface (21) of the first support (2) is spliced with a support surface (102) of the first housing (10) to form a first support surface (401). One end of the second support (3) is rotatably connected to the middle housing (1), and the other end is fixedly connected to the second housing (30). A support surface (31) of the second support (3) is spliced with a support surface (302) of the second housing (30) to form a second support surface (402). When the first housing (10) and the second housing (30) are folded relative to each other to a closed state, the first support (2) and the second support (3) are far away from each other, and the first support surface (401) and the second support surface (402) gradually approach each other in a direction away from the middle housing (1). A main moving mechanism of the rotation mechanism (20) of the folding apparatus (100) has a small quantity of parts, so that control precision is high.

摘要： This application relates to the field of IT technologies, and in particular, to a method, an apparatus, and a system for discovering an application topology relationship between virtual machines. According to the method for discovering an application topology relationship provided by this application, in a packet transmission process, API calling information is recorded, and a topology discovery server determines, by analyzing collected API calling information, whether interaction exists between virtual machines in a virtual machine cluster. By using the foregoing analysis manner, the topology discovery server may further determine interaction frequency that is between virtual machines and to which the collected API calling information relates, and determine an application topology relationship between the virtual machines according to the interaction frequency of the virtual machines. The foregoing solution provides a method for discovering an application topology relationship between virtual machines in a virtualization scenario, where an application topology relationship between virtual machines is determined by analyzing API calling information generated in a packet transmission process, and therefore complexity of the solution is relatively low.

摘要： This application discloses a folding mechanism and an electronic device. The folding mechanism is applied to a housing apparatus of an electronic device, and is configured to connect two housings of the housing apparatus. The folding mechanism can form display accommodating space through automatic avoidance in a folding process, and a flexible display is accommodated in the display accommodating space, so that a folding action performed by the housing apparatus on the flexible display is stable, and a squeezing force is small. This helps reduce a risk that the flexible display is damaged due to excessive squeezing of the folding mechanism, and makes the flexible display more reliable.
