In the description of the present invention, "a plurality" means two or more unless otherwise specified. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
A specific structure of a display device of an embodiment of the present invention is described below with reference to fig. 1 to 15.
As shown in fig. 1-15, fig. 1 discloses a display device comprising a support 1, a transmission assembly 2, a flexible screen 3 and a driving assembly 4. The transmission component 2 is rotatably connected to the bracket 1, and the middle part of the transmission component 2 can move towards opposite directions with the two ends of the transmission component 2. The flexible screen 3 is connected with at least the middle part of the transmission component 2 and the two ends of the transmission component 2, and the flexible screen 3 has a curved surface state and a straight surface state. The driving assembly 4 is arranged in the bracket 1, the output end of the driving assembly 4 is connected with the transmission assembly 2, and the driving assembly 4 can drive the transmission assembly 2 to move so as to switch the flexible screen 3 between a curved surface state and a straight surface state.
It can be understood that when the middle part of the transmission assembly 2 is stressed, the middle part and the two ends of the transmission assembly 2 move towards opposite directions, and the flexible screen 3 is connected with the middle part and the two ends of the transmission assembly 2, so that the middle part and the two ends of the flexible screen 3 also move towards opposite directions under the action of the flexible screen 3. As shown in fig. 1 and 5, when the flexible screen 3 is in a curved surface state, the middle part and the two ends of the flexible screen 3 are arranged at intervals in the front-back direction, the driving component 4 can drive the transmission component 2 to move at the moment, the middle part and the two ends of the transmission component 2 move in opposite directions, and then the middle part and the two ends of the flexible screen 3 move in opposite directions, when the middle part and the two ends of the flexible screen 3 are located at the same position in the front-back direction, the flexible screen 3 enters a straight surface state immediately, the driving component 4 stops driving the transmission component 2 to move at the moment, and the flexible screen 3 can be kept in the straight surface state under the limit of the transmission component 2. As shown in fig. 2 and 6, similarly, when the flexible screen 3 is in a straight-face state, the driving assembly 4 drives the transmission assembly 2 to move, the middle part and the two ends of the transmission assembly 2 move back to back, so as to drive the middle part and the two ends of the flexible screen 3 to move back to back, when the middle part and the two ends of the flexible screen 3 have a preset distance in the front-back direction, the flexible screen 3 enters a curved-face state, the driving assembly 4 stops driving the transmission assembly 2 to move, and the flexible screen 3 can be kept in the curved-face state under the limit of the transmission assembly 2.
According to the display device of the embodiment, the switching of the curved panel between the straight state and the curved state can be well realized through the transmission assembly 2 with a simple structure, the driving cost of the curved-straight switching of the curved panel can be remarkably reduced, and the production cost of the display device is reduced while the reliable switching of the display device between the curved state and the straight state is ensured.
In some embodiments, as shown in fig. 4-6, the bracket 1 defines a first curved surface 11, and the flexible screen 3 conforms to the first curved surface 11 when in the curved state.
It can be understood that, when the flexible screen 3 is in the curved state, the first arc surface 11 on the bracket 1 can provide a supporting effect for the flexible screen 3, so that the flexible screen 3 can be stably maintained in the curved state, and the possibility that the flexible screen 3 is separated from the curved state under the action of an external force is reduced. In addition, first cambered surface 11 can also play spacing effect to the motion of flexible screen 3, and when flexible screen 3 laminated first cambered surface 11, even drive assembly 4 continued drive transmission assembly 2 motion, the central axis of flexible screen 3 was in support 1 spacing also can't continue back of the body motion with the both ends of flexible screen 3 down to the security when flexible screen 3 switched between curved surface state and the straight face state has been improved.
In some embodiments, as shown in fig. 5 and 6, the transmission assembly 2 comprises a first transmission member 21 and two second transmission members 22. The first transmission member 21 is arranged on the flexible screen 3 and connected with the output end of the driving assembly 4. The two first transmission pieces 21 are arranged on two sides of the first transmission piece 21, the second transmission piece 22 is rotatably connected to the support 1, and two ends of the second transmission piece 22 are rotatably connected with the first transmission piece 21 and the flexible screen 3 respectively.
It can be understood that, when the driving assembly 4 drives the first transmission member 21 to move towards the direction away from the support 1, the first transmission member 21 will drive the connection end of the first transmission member 22 and the middle part of the flexible screen 3 to move towards the direction away from the support 1, at this time, the second transmission member 22 rotates relative to the support 1, and the other end of the second transmission member 22 moves towards the direction close to the support 1, and the other end of the second transmission member 22 is rotationally connected with the flexible screen 3, so that the second transmission member 22 drives the end part of the flexible screen 3 to move towards the direction close to the support 1, that is, the middle part and the two ends of the flexible screen 3 move away from each other. Similarly, when the driving assembly 4 drives the first transmission member 21 to move towards the direction approaching the support 1, due to the rotational connection relationship among the first transmission member 21, the second transmission member 22, the flexible screen 3 and the support 1, the middle portion of the flexible screen 3 can move towards the direction approaching the support 1, and the two ends of the flexible screen 3 can move towards the direction away from the support 1, so that the middle portion and the two ends of the flexible screen 3 can move in opposite directions, the specific action process of the flexible screen is similar to the back-to-back movement of the middle portion and the two ends of the flexible screen 3, and the description is not needed. Obviously, the first transmission member 21 and the two second transmission members 22 have only three transmission structures, so that the motion reliability and the assembly cost of the transmission assembly 2 can be greatly reduced.
In some specific embodiments, as shown in fig. 1, 2 and 4, the first transmission member 21 and the second transmission member 22 are both transmission plates, and the transmission plates have a large width, so that the large-sized flexible screen 3 can be conveniently driven to move, the problem of bending collision between the flexible screen 3 and the first transmission member 21 or the second transmission member 22 is prevented, and the service life of the display device is prolonged.
In some specific embodiments, as shown in fig. 4, the bracket 1 includes a base 12, a supporting frame 13 and a fixing frame 14, the supporting frame 13 is disposed on the base 12, the fixing frame 14 is disposed on the supporting frame 13, the first arc surface 11 is disposed on the fixing frame 14, and the driving assembly 4 is disposed in the supporting frame 13.
In some embodiments, as shown in fig. 5-7, the middle part of the second transmission piece 22 and the support 1 are rotationally connected by an eccentric shaft 23.
It can be understood that, when the first transmission member 21 is driven by the driving assembly 4 to move in the front-back direction, the first transmission member 21 will simultaneously drive the joints with the two second transmission members 22 to move in the front-back direction, so that the distances between the joints between the second transmission members 22 and the first transmission member 21 and between the joints between the second transmission members 22 and the support 1 will actually slightly change, and if the joints between the second transmission members 22 and the support 1 and between the second transmission members 21 are connected by the common rotating shaft 25, the whole mechanism will easily be jammed. In this embodiment, since the rotation axes of the second transmission member 22 and the eccentric shaft 23 are parallel to and do not coincide with the rotation axes of the bracket 1 and the eccentric shaft 23, the rotation axis at the joint of the eccentric shaft 23 and the bracket 1 can be kept fixed, and the rotation axis at the joint of the eccentric shaft 23 and the second transmission member 22 can move along with the movement of the first transmission member 21, so as to better solve the possible locking problem of the transmission assembly 2, the bracket 1 and the flexible screen 3 in the movement process, and ensure that the driving assembly 4 can realize the switching of the flexible screen 3 between the curved surface state and the straight surface state through the transmission assembly 2. Of course, in other embodiments of the present invention, the above-mentioned distance variation problem can be avoided by setting the second transmission member 22 to be a telescopic structure, and therefore, the rotary connection structure between the second transmission member 22 and the bracket 1 in other embodiments of the present invention can be determined according to actual requirements without specific limitations.
In some specific embodiments, as shown in fig. 7, one end of the eccentric shaft 23 is rotatably inserted into the second transmission member 22, and the other end is provided with a through hole, and the eccentric shaft 23 is connected to the bracket 1 through a connecting member 24 inserted into the through hole.
In some embodiments, as shown in fig. 1, 4 and 6, the second transmission member 22 has a second arc surface 221, and the flexible screen 3 is in a curved state and fits the second arc surface 221.
It can be understood that the second cambered surfaces 221 can also provide a supporting effect for the flexible screen 3, so that the flexible screen 3 can be stably maintained in a cambered state, and the possibility that the flexible screen 3 is separated from the cambered state under the action of an external force is reduced. The second cambered surface 221 also can play a limiting effect on the movement of the flexible screen 3, and when the flexible screen 3 is attached to the second cambered surface 221, even if the driving component 4 continues to drive the transmission component 2 to move, the central axis of the flexible screen 3 is positioned at the position of the second transmission component 22, and the central axis of the flexible screen cannot move back to back with the two ends of the flexible screen 3, so that the safety of the flexible screen 3 in switching between a curved surface state and a straight surface state is improved.
In some specific embodiments, the joints between the first transmission member 21, the second transmission member 22 and the flexible screen 3 are all rotationally connected through a rotating shaft 25 extending in the vertical direction. Because the flexible screen 3 has a height, the transmission reliability between the first transmission member 21, the second transmission member 22 and the flexible screen 3 can be improved by the above-described structural arrangement.
In some embodiments, as shown in fig. 8-10, the transmission assembly 2 further comprises a third transmission member 26, one end of the transmission assembly 2 is connected to the output end of the driving assembly 4, and the other end is connected to the first transmission member 21, a guide member 15 is disposed in the bracket 1, and the guide member 15 is used for guiding the movement direction of the third transmission member 26 to be perpendicular to the flexible screen 3.
It can be understood that, because the drive assembly 2 needs to drive the flexible screen 3 to move along the fore-and-aft direction, through the setting of third driving medium 26 and guide 15 in this embodiment, can be better with the drive assembly 4 to the drive power conversion of the arbitrary direction of third driving medium 26 the direction of perpendicular to flexible screen 3, and then can be convenient for drive assembly 4 to move and realize drive assembly 2 and drive flexible screen 3 along the fore-and-aft direction motion through driving third driving medium 26, thereby realized the conversion of flexible screen 3 at curved surface state and straight surface state betterly. Meanwhile, the output direction of the driving assembly 4 is not limited any more, so that the driving assembly 4 can adopt a driving structure with a smaller volume, the volume of the whole driving assembly 4 is reduced, and the driving assembly 4 can be stably installed in the common bracket 1.
In some specific embodiments, the guiding element 15 includes two bending guiding blocks, the two guiding blocks are spaced apart to form a guiding groove, one end of the guiding groove extends along the front-back direction, and the other end extends along the vertical direction, so that the movement of the third transmission member 26 in the vertical direction can be converted into the movement in the front-back direction. Of course, in other embodiments of the present invention, the guide 15 may be formed in other structures, and need not be specifically limited herein.
In some embodiments, as shown in fig. 8-11, the conveying direction of the driving assembly 4 is arranged along the vertical direction, and the third transmission member 26 includes an elastic guide bar, and the elastic guide bar is provided with a groove 261 extending along the length direction thereof.
It can be understood that after the groove 261 is opened on the elastic conducting bar, the strength of the elastic conducting bar in the vertical direction can be improved, and meanwhile, the direction of the face opened by the groove 261 is easier to bend under the action force of the driving piece, so that the elastic conducting bar can be easily switched from vertical motion to horizontal motion under the action of the guide piece 15, the installation of the driving component 4 on the support 1 is convenient to realize, and the attractiveness of the whole display device is improved.
In particular, in this embodiment, the grooves 261 are opened on the side walls of the elastic guide bars facing the flexible screen 3, and when the elastic guide bars are bent in the front-rear direction,
in some embodiments, as shown in fig. 9, the driving assembly 4 includes a power source 41, a lead screw 42 and a guide post 43, the lead screw 42 is connected to the output end of the power source 41, the lead screw 42 is connected to the transmission assembly 2, and the guide post 43 is inserted into the transmission assembly 2.
It can be understood that the common driving structures such as the motor and the cylinder often have larger volume and operation noise, are inconvenient to install on the display device, and even if the driving structures are installed on the display device, the noise is easy to generate and the attractiveness of the display device is affected, so that the use experience of a user is greatly reduced. The structure can better ensure that the driving component 4 drives the transmission component 2 to move, the guide pillar 43 can prevent the movement direction of the transmission component 2 from deviating from the vertical direction and interfering with the bracket 1, and the use reliability and the service life of the display device are prolonged. Meanwhile, the lead screw 42 can adopt a small lead screw 42 structure, so that the lead screw can be conveniently assembled in the bracket 1 and has less noise.
In some embodiments, as shown in fig. 12 and 13, the drive assembly 4 further comprises a pusher 44 and a stop 45. The pushing piece 44 is arranged on the bracket 1 in a penetrating way and is connected with the transmission component 2. The limiting piece 45 is movably arranged in the support (1) in a penetrating mode, and when the flexible screen 3 is located in a curved surface state or a straight surface state, the pushing piece 44 is locked by the limiting piece 45.
It can be understood that the pushing member 44 can facilitate the user to manually adjust the curved state and the linear state of the flexible screen 3, thereby facilitating the user to switch the state of the flexible screen 3 in an emergency, and improving the user experience. The distance between the flexible screen 3 and the support 1 when being in the straight surface state is larger than the distance between the flexible screen 3 and the support 1 when being in the curved surface state, when the flexible screen 3 is in the straight surface state or the curved surface state, the pushing part 44 is locked through the limiting part 45, the flexible screen 3 can be prevented from being separated from the straight surface state or the curved surface state under the action of external force, and therefore the reliability of the flexible screen 3 in the straight surface state or the curved surface state is further improved.
Specifically, in the present embodiment, when the flexible screen 3 is in the curved state, the stopper 45 locks the pushing member 44.
In some specific embodiments, the limiting member 45 is movably connected to the bracket 1, the limiting member 45 is provided with a button 451 penetrating through the bracket 1, one of the limiting member 45 and the pushing member 44 is provided with an insertion port 441, and the other is provided with an insertion protrusion 452. When a user presses the button 451, the user can drive the insertion port 441 and the insertion protrusion 452 to be disengaged, so that the limiting piece 45 releases the pushing piece 44, and similarly, the insertion port 441 can be matched with the insertion protrusion 452 during the movement of the pushing piece 44, so that the limiting piece 45 locks the pushing piece 44. Specifically, the insertion port 441 is disposed on the pushing member 44, and the insertion protrusion 452 is disposed on the limiting member 45.
In some embodiments, as shown in fig. 14 and 15, the driving assembly 4 includes two magnetic attracting elements 46, one magnetic attracting element 46 is disposed on the transmission assembly 2, and the other magnetic attracting element 46 is disposed on the bracket 1, and the two magnetic attracting elements 46 can drive the transmission assembly 2 to move when being separated or attracted.
It can be understood that when the two magnetic attraction pieces 46 attract each other, the flexible screen 3 can be kept abutting against the bracket 1, so that the flexible screen 3 can be stably kept in a curved state, and the flexible screen 3 is prevented from returning to a straight state under the action of external force. When the flexible screen 3 needs to enter the straight state, the user can manually separate the two magnetic attraction pieces 46 by the flexible screen 3. Of course, in other embodiments of the present invention, one magnetic member 46 includes two magnetic portions, and the other magnetic member 46 includes two electromagnets with opposite polarities, so that the flexible screen 3 can be automatically switched between the curved state and the straight state by energizing different electromagnets.
