When the flexible display panel 200 is pulled out of the casing along with the movement of the comb teeth 107, since the comb teeth 107 are fixed to the two first side plates and remain stationary, the length of the comb teeth 107 fitted in the comb teeth 108 becomes shorter gradually as the comb teeth 107 slide away from the fixed casing 103, and the length of the comb teeth 107 fitted in the comb teeth 108 becomes longer gradually as the flexible display panel 200 is retracted into the fixed casing 103 along with the sliding of the comb teeth 107, the comb teeth 107 slide toward the direction approaching the comb teeth 108. Therefore, during the movement of the comb teeth 107, the teeth slots 108 and the comb teeth 107 always have an overlapping area, so that the portion of the flexible display panel 200 outside the cabinet is supported at any position.

In one embodiment, the length of the comb teeth 107 is smaller than or equal to the length of the tooth grooves 108, so that when the comb teeth 107 slide to the display area of the flexible display panel 200 to be in a contracted state, the comb teeth 107 are completely embedded into the tooth grooves 108 in the length direction, the tooth grooves 108 and the comb teeth 107 are mutually matched, no larger gap exists between the tooth grooves 108 and the comb teeth 107, and all parts are supported when the flexible display panel 200 is touched, so that the touch effect is improved.

The motor is regulated by the motor controller to control the speed at which the flexible display panel 200 moves the movable housing 104, and thus control the tension of the flexible display panel 200, so that the flexible display panel 200 can maintain a fixed tension in the process of being unfolded. However, the present embodiment is not limited thereto. The driving part may be other structures capable of driving the flexible display panel 200 and the second chassis 102 to move. It will be appreciated that, in a specific application, those skilled in the art may also select driving members such as a motor, an electric motor, and a hydraulic motor as the first driving member according to actual needs, and the embodiment of the present invention may not be limited to the specific content of the driving device 302.

In this embodiment, please continue to refer to fig. 7-8, the reset assembly 400 includes a push rod 402 disposed on the fixed housing 103, one end of the push rod 402 is fixedly connected to the movable housing 104, and the other end of the push rod 402 is provided with a pushing block 407 contacting with the elastic member 401; the push rod 402 is further provided with a fixing block 403 fixedly connected with the traction rope 301.

In some embodiments, the fixing block 403 may be a screw fixed on the push rod 402, and the traction rope 301 is sleeved on the screw, so as to facilitate installation, fixing and detachment. When the traction assembly 300 drives the push rod 402 to move towards the direction close to the fixed housing 103, the pushing block 407 on the push rod 402 compresses the elastic member 401 downwards, and when the driving device 302 tightens the traction rope 301, the elastic member 401 can apply an upward reverse acting force to the traction rope 301, so that the stability of the movable housing 104 is improved. When the driving device 302 releases the traction rope 301, the elastic force of the elastic member 401 is applied to the pushing block 407 to drive the push rod 402 to move upwards, so that the movable housing 104 can be switched to the unfolded state.

The reset assembly 400 further comprises a first stop block 404, a second stop block 405 and a limit rod 406, wherein the first stop block 404 and the second stop block 405 are arranged on the fixed housing 103, the limit rod 406 is sleeved with the elastic piece 401 and the pushing block 407, and one end of the elastic piece 401 is in contact with the second stop block 405. The first stop block 404 and the second stop block 405 may be used to limit the relative limit positions of the movable housing 104 and the fixed housing 103, improve the movement stability, and prevent the movable housing 104 from being separated from the fixed housing 103 or from being crushed against the fixed housing 103.

The elastic member 401 is a compression spring, and the compression spring is in a compressed state when the flexible display panel 200 is in an expanded state. In this application, when the traction assembly 300 pulls the movable housing 104 to move to a side close to the fixed housing 103, the traction force applied by the driving assembly to the movable housing 104 is greater than the rebound force applied by the elastic member 401 to the movable housing 104; when the reset assembly 400 drives the movable housing 104 to move to the side away from the fixed housing 103, the driving device 302 stops applying traction force to the movable housing 104. By controlling the resilience of the elastic member 401 and the traction force, the movement accuracy between the sliding housing and the fixed housing 103 can be effectively controlled, and the movement jamming phenomenon can be prevented.
