The flexible display device is an important display device, has been developed in recent years, and has the characteristics of being bendable and flexible compared with the traditional screen, so that the application scene of the flexible display device is wider and wider, and the flexible display device is particularly suitable for wristband mobile phones.
However, since the present flexible display device has flexibility, the flexible display device has a certain elastic restoring capability, so that the flexible display device can be in two states of full winding or flat unwinding, and the flexible display device has a certain limitation in use.
In view of this, as shown in fig. 1-8, an embodiment of the present application provides a flexible display panel spacing mechanism 100, comprising: a support assembly 1, the support assembly 1 being bendable; a hovering component 2 connected to the supporting component 1 for maintaining the supporting component 1 in a hovering state in the absence of an external force. Here, the hovering state refers to a state in which the support assembly 1 remains relatively stationary without being subjected to an external force. The support assembly 1 is for supporting a display panel, and has substantially the same plate shape as the display panel as a whole.
As shown in fig. 2, wherein the support assembly 1 is used for supporting a flexible display panel, the support assembly 1 is bendable; the hovering assembly 2 is arranged on the supporting assembly 1, the hovering assembly 2 comprises a locking element 201 and a detent 202, the locking element 201 being adapted to releasably lock the detent 202 to hold the supporting assembly 1 in a hovering state.
As shown in fig. 1 and fig. 2, the flexible display panel limiting mechanism 100 provided by the embodiment of the application includes a supporting component 1 and a hovering component 2, in the use process of the flexible display panel limiting mechanism 100, the flexible display panel can be arranged on the supporting component 1, the supporting component 1 can be bent to drive the flexible display panel to bend, and the hovering component 2 is connected to the supporting component 1, so that the supporting component 1 maintains the current state under the condition of not being subjected to external force, and the flexible display panel arranged on the supporting component 1 can be in the hovering state, thereby being capable of enabling the flexible display panel to be randomly switched among the flattening, the full winding and the intermediate states between the flattening and the full winding, enabling the flexible display panel to have more display states, being applicable to different application scenes, meeting the requirement of users on multi-state display of the flexible display device, and greatly improving the application range of the flexible display device.
Illustratively, the support assembly 1 may be made of a rubber material having elasticity that allows the support assembly 1 to bend; alternatively, the support assembly 1 may comprise a plurality of support units, with hinges between adjacent support units, which may also allow the support assembly 1 to flex. During bending of the support assembly 1, there is a force for deformation restoration of the support assembly 1. By arranging the hovering element 2 at one side of the supporting element 1, resistance can be applied to the supporting element 1 to resist the force of deformation and restoration of the supporting element 1, i.e. the supporting element 1 can be maintained in the current bending state, so that the supporting element 1 can be switched between the flattened, fully wound and intermediate states between the flattened and fully wound.
It will be appreciated that when an external force is applied to the support assembly 1, in case the external force is greater than the force applied by the hover assembly 2 to the support assembly 1, the support assembly 1 may change the current state to make a change of the bending state. For example, the support assembly 1 may be bent by human force to overcome the force applied by the hover assembly 2 to the support assembly 1, such that the support assembly 1 is further bent or flattened.
Illustratively, the hover component 2 may exert a force on the support component 1 against the force of the support component 1 deformation return by any form of force, magnetic force, elastic force, frictional force, etc.
According to the flexible display panel limiting mechanism 100 provided by the embodiment of the application, the hovering component 2 comprises the locking piece 201 and the clamping device 202, in the using process of the flexible display panel limiting mechanism 100, part of the clamping device 202 is inserted into the locking piece 201, and under the condition that the clamping device 202 is inserted into the locking piece 201, the clamping device hovering component 2 can apply resistance to the supporting component 1, the resistance can overcome the elasticity of deformation or reset of the supporting component 1, so that the supporting component 1 can be locked, the supporting component 1 is maintained in the current bending state, and the flexible display panel arranged on the supporting component 1 is in the hovering state. Thus, the display panel can be arbitrarily switched between the flat state, the fully wound state, and the intermediate state between the flat state and the fully wound state. In case the applied external force exceeds the force exerted by the hovering element 2 on the supporting element 1, the supporting element 1 may undergo a change of bending state.
Illustratively, as shown in fig. 2 to 4, the disassembled state of the hover component 2 is shown from three viewing angles. Mounting holes can be formed in the side face of the support assembly 1, and the locking piece 201 and the clamping device 202 of the hovering assembly 2 can be fixed in the mounting holes through screws or pins.

The support assembly 1 can be locked with the slider 2021 inserted into the locking member 201, so that the support assembly 1 is in a hovering state, and the support assembly 1 can maintain a current bending state. When an external force is applied to the support assembly 1, the external force can overcome the elastic force of the first elastic member 2022, the sliding member 2021 is separated from the locking member 201, the support assembly 1 is unlocked, and the support assembly 1 can bend under the action of the external force. It can be appreciated that when the applied external force is eliminated, the first elastic member 2022 applies an elastic force to the sliding member 2021, so that the sliding member 2021 is slidably inserted into the locking member 201, the supporting assembly 1 is locked again, and the supporting assembly 1 can maintain the current bending state. Based on the method, the display panel can be randomly switched among the flattening state, the full winding state and the intermediate state between the flattening state and the full winding state, so that the display panel has more display states, is suitable for different application scenes, meets the requirement of a user on multi-state display of the flexible display device, and greatly improves the application range of the flexible display device.

The sliding space in the bracket 203 can play a role in limiting and guiding the sliding part 2021, so that the sliding part 2021 can only move along the elastic direction of the first elastic part 2022, the working stability of the hovering component 2 is ensured, the hovering accuracy of the supporting component 1 is ensured, and the failure rate is reduced.
