[0045] As shown in Figures 1 to 8 the present application provides a display device, which comprises a middle frame 11, a driving assembly 12, a motor fixing plate 13, a screen fixing plate 14 and a display screen 15. The middle frame 11 comprises a middle frame fixing plate 21 and a middle frame sliding plate 22 in sliding connection with the middle frame fixing plate 21. The driving assembly 12 is connected with the middle frame sliding plate 22 and is configured to drive the middle frame sliding plate 22 and the middle frame fixing plate 21 to move in opposite directions or in opposite directions. The motor fixing plate 13 is fixedly connected with the driving assembly 12 and is fixedly connected with the middle frame sliding plate 22. The screen fixing plate 14 is connected with the motor fixing plate 13. The display screen 15 comprises a support plate 151. One end of the support plate 151 is fixedly connected with the middle frame fixing plate 21, and the other end of the support plate 151 is connected with the screen fixing plate 14.

[0046] The display device 1 further comprises a first connecting structure 31, the motor fixing plate 13 and the screen fixing plate 14 are connected through the first connecting structure 31, the first connecting structure 31 is provided with an elastic structure 311, the elastic structure 311 is arranged between the motor fixing plate 13 and the screen fixing plate 14, and the elastic structure 311 is in a compressed state.

[0047] The display device provided by the embodiment of the application is characterized in that the motor fixing plate and the screen fixing plate are arranged, the motor fixing plate is fixedly connected with the driving assembly, the screen fixing plate is connected with the support plate, the motor fixing plate and the screen fixing plate are connected through the first connecting structure, the first connecting structure is provided with the elastic structure, the elastic structure is arranged between the motor fixing plate and the screen fixing plate, and the elastic structure is in a compressed state, so that the motor fixing plate and the screen fixing plate have a mutual reaction force under the elastic force of the elastic structure, the screen fixing plate is connected with the support plate, so that the screen fixing plate generates a pulling force on the display screen, and the display screen is in a pre-tightening state, meanwhile, the motor fixing plate is fixedly connected with the middle frame sliding plate, so that the relative position of the motor fixing plate and the screen fixing plate does not change, that is, the display screen is subjected to a pulling force in the state of being contracted or expanded, thereby preventing the display screen from being curled and arched, and avoiding damage to the display screen.

[0048] Specifically, the first connecting structure comprises a first screw.

[0049] Specifically, when the display screen is not bonded with the middle frame, the motor fixing plate 13 and the screen fixing plate 14 can have a certain gap (considering the machining error of the mechanism, the gap between the two can be 0.2 mm), after the support plate of the display screen is bonded or fixed with the screen fixing plate, the first screw can be twisted, since the elastic structure is in a compressed state in the initial state, with the twisting of the first screw, the motor fixing plate and the screen fixing plate will automatically separate and generate a mutual force under the action of the elastic structure, that is, there is a force between the motor fixing plate and the screen fixing plate, which makes the elastic structure indirectly give the display screen a pulling force, when the display device is in a static state, since the display screen has a pulling force, the display screen will not be arched, the display effect is improved, and when the display device is contracted or expanded, since the elastic structure will always give a force, the display screen can be prevented from being arched, and the display device can be prevented from being damaged.

[0050] Specifically, it can be understood that before the display screen is installed, the elastic structure will be in a compressed state under the compression force of the first screw, after the screw is twisted, the elastic structure will automatically stretch, but it is still in a compressed state, so that the elastic structure can indirectly give the display screen a pulling force and exert a pre-tightening force on the display screen, preventing the display screen from being arched.

[0051] Specifically, it can be understood that a tension of 8 Newtons can make the display screen present a tight state and not appear arching and other problems, and thus the elastic structure can indirectly give the display screen a tension of 8 Newtons when the display device is assembled, but the embodiments of the present application are not limited thereto, and according to different display screens, the display screen needs different tensions, and the compression degree of the elastic structure can be adjusted accordingly to indirectly give the display screen a tension of a corresponding size.

[0052] Specifically, it can be understood that the display device in the embodiments of the present application is a slidable display device, and thus the relative positions of the structures presented by the display device in different states will be different. Specifically, the display device includes an unfolded state and a storage state, and the storage state refers to the state in which the middle frame sliding plate is closest to the middle frame fixed plate. For example, when the relative positions of the middle frame sliding plate and the middle frame fixed plate are different, the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate ranges from 1 to 10, and when the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 1, it is considered that the display device is in the storage state, and when the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is greater than 1, it is considered that the display device is in the unfolded state, and when the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 10, it is considered that the display device is in a completely unfolded state.

[0053] Specifically, it can be understood that the relative positions of the components in each unfolded state will be different due to different unfolding degrees of the display device, but it can be determined that the relative positions of the components in each unfolded state can be determined in the state in which the display device is in the completely unfolded state and the storage state, and the transition process between each unfolded state can refer to the transition process from the unfolded state to the storage state. For example, when the display device is in a state in which the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 2 and is changed to a state in which the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 3, the transition process can refer to the process in which the display device is changed from the storage state to the unfolded state, and conversely, when the display device is in a state in which the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 3 and is changed to a state in which the distance between the upper end of the middle frame sliding plate and the upper end of the middle frame fixed plate is 2, the transition process can refer to the process in which the display device is changed from the unfolded state to the storage state.

[0054] Specifically, it can be understood that the display device includes a front surface and a back surface, and a part of the display screen will remain on the front surface of the display device when the display device is in the unfolded state and the storage state. Therefore, one end of the support plate is fixedly connected with the middle frame fixed plate, which means that the one end of the support plate is connected with the front surface of the middle frame fixed plate (which can be bent to the lower side or the rear side), and the other end of the support plate is connected with the screen body fixed plate on the back surface of the display device when the middle frame sliding plate is unfolded.

[0055] Specifically, when the first connecting structure is a first screw, the motor fixing plate and the screen body fixing plate have screw holes corresponding to the first screw. The first screw can be a half-threaded inner hexagonal screw. It can be understood that, correspondingly, the motor fixing plate and the screen body fixing plate have screw holes corresponding to the half-threaded inner hexagonal screw.

[0056] In some embodiments, as shown in Figure 1 , Figure 5 The driving assembly 12 includes a motor 121, a first fixed sliding block 122, and a second fixed sliding block 123. The first fixed sliding block 122 is fixedly connected to the middle frame fixing plate 21. The motor 121 is configured to drive the second fixed sliding block 123 to move towards the first fixed sliding block 122 or away from the first fixed sliding block 122.

[0057] In some embodiments, as shown in Figure 2 The display screen 15 further includes a display panel 152. The support plate 151 is disposed on a side of the display panel 152 close to the middle frame fixing plate 21. The support plate 151 is disposed on a side of the display panel 152 close to the middle frame sliding plate 22. The support plate 151 extends beyond the display panel 152. The portion of the support plate 151 extending beyond the display panel 152 is connected to the screen body fixing plate 14. By disposing the support plate on a side of the display panel close to the middle frame fixing plate and on a side of the display panel close to the middle frame sliding plate, the display panel can be supported by the support plate to prevent the display panel from collapsing. The display panel and other structures can be separated by the support plate to prevent the display panel from being damaged when the telescopic roller is extended or retracted. The support plate extends beyond the display panel. The portion of the support plate extending beyond the display panel can be connected to the screen body fixing plate. Thus, the display screen can be given a pre-tightening force by the screen body fixing plate, the motor fixing plate, the first connecting structure, and the elastic structure to prevent the display screen from arching. The support plate contacts the screen body fixing plate to prevent the display panel from being damaged due to contact with the screen body fixing plate.

[0058] Specifically, as shown in Figure 2 It can be seen that a portion of the support plate 151 extends beyond the display panel 152, and another portion of the support plate 151 is located below the display panel 152. The support plate 151 is connected to the screen body fixing plate 14. The support plate 151 can drive the entire display screen to move without the display panel contacting the screen body fixing plate 14 to prevent damage to the display panel.

[0059] Specifically, it can be understood that the display screen can also include other structures, such as a cover plate, a polarizing sheet, and when the display screen is an organic light-emitting diode display screen, a polarizing sheet and a cover plate can be arranged on the side of the display panel away from the support plate, and the film layers are bonded by the adhesive layer, which will not be described here.

[0060] Specifically, the material of the support plate can be stainless steel, and the bending performance of the support plate can be improved by thinning the thickness of the support plate and forming a via hole on the support plate.

[0061] In some embodiments, as shown in Figure 2 、 Figure 3 The screen body fixing plate 14 includes a plurality of fixing columns 141, the support plate 151 includes a plurality of via holes 151a, the via holes 151a are arranged correspondingly with the fixing columns 141, and the fixing columns 141 are arranged in the via holes 151a. By arranging a plurality of fixing columns on the screen body fixing plate 14, a plurality of via holes on the support plate, and arranging the fixing columns in the via holes, the screen body fixing plate and the support plate can be fixedly connected, so that the screen body fixing plate and the support plate can move synchronously, and correspondingly, the screen body fixing plate and the display screen can move synchronously.

[0062] Specifically, the fixing columns can be arranged beyond the screen body fixing plate, the centers of the plurality of fixing columns can be located on the same straight line, the spacing between any two adjacent fixing columns is equal, and correspondingly, the centers of the plurality of via holes can be located on the same straight line. By arranging a plurality of fixing columns on the screen body fixing plate and a plurality of via holes on the support plate, the fixing effect of the screen body fixing plate and the support plate is good, and the pulling force on each region of the support plate can be uniformly fixed, so that the display screen does not drift when sliding, or the display screen is not damaged due to excessive pulling force in a certain region.

[0063] Specifically, as shown in Figure 1 The screen body fixing plate can also be fixedly connected with the middle frame sliding plate, a threaded hole can be arranged on the screen body fixing plate, a corresponding threaded hole can be arranged on the middle frame sliding plate, and the screen body fixing plate and the middle frame sliding plate can be fixed by a screw.

[0064] Specifically, the above embodiments take the screen body fixing plate and the support plate connected by the fixing columns and the via holes as an example for description, but the embodiments of the present application are not limited thereto, for example, the screen body fixing plate and the support plate can be connected by a screw and a threaded hole, and the screen body fixing plate and the support plate can also be bonded by an adhesive.

[0065] In some embodiments, as shown in Figure 5 、 Figure 6 、 Figure 9As shown, the motor fixing plate 13 is provided with a first connecting hole 13a, the second fixing sliding block 123 is provided with a second connecting hole 123a, the first connecting hole 13a and the second connecting hole 123a are correspondingly arranged, and the display device 1 further includes a second connecting structure 32 arranged in the first connecting hole 13a and the second connecting hole 123a. By arranging the first connecting hole on the motor fixing plate and the second connecting hole on the second fixing sliding block, the motor fixing plate can be fixed with the second fixing sliding block, and when the driving assembly drives the second fixing sliding block to move, the motor fixing plate can be driven to move synchronously, so that the distance between the motor fixing plate and the screen fixing plate remains unchanged, an indirect tension is applied to the display screen, the display screen is kept in a tight state, and the display screen is prevented from arching.

[0066] Specifically, the second connecting structure can be a second screw, which can be a half-threaded hexagonal screw or other screws.

[0067] Specifically, it can be understood that when the second screw is used to connect the motor fixing plate and the second fixing sliding block, the first connecting hole and the second connecting hole can be threaded holes.

[0068] Specifically, the second fixing sliding block can also be fixedly connected with the middle frame sliding plate, and the second fixing sliding block and the middle frame sliding plate can be fixed by the connecting hole and the screw.

[0069] Specifically, as shown in Figure 1 The motor fixing plate 13 includes a first motor fixing plate 131 and a second motor fixing plate 132, the first motor fixing plate 131 and the second motor fixing plate 132 are arranged on both sides of the display device 1, and the first motor fixing plate 131 and the second motor fixing plate 132 can be connected with the screen fixing plate 14.

[0070] As shown in Figure 1 , Figure 3As shown, the first connecting structure 31 includes a first half-threaded inner hexagonal screw 31a, a second half-threaded inner hexagonal screw 31b, a third half-threaded inner hexagonal screw 31c, and a fourth half-threaded inner hexagonal screw 31d, the elastic structure 311 includes a first spring 311a, a second spring 311b, a third spring 311c, and a fourth spring 311d, the first spring 311a, the second spring 311b, the third spring 311c, and the fourth spring 311d are respectively arranged on the first half-threaded inner hexagonal screw 31a, the second half-threaded inner hexagonal screw 31b, the third half-threaded inner hexagonal screw 31c, and the fourth half-threaded inner hexagonal screw 31d, the first motor fixing plate 131 and the screen body fixing plate 14 are connected through the first half-threaded inner hexagonal screw 31a and the second half-threaded inner hexagonal screw 31b, and the second motor fixing plate 132 and the screen body fixing plate 14 are connected through the third half-threaded inner hexagonal screw 31c and the fourth half-threaded inner hexagonal screw 31d.

[0071] In some embodiments, as shown in Figure 1 、 Figure 5 、 Figure 10 As shown, the first fixed sliding block 122 includes a sliding block body 122a and a connecting rod 122b, the sliding block body 122a is connected with the connecting rod 122b, a plurality of first through holes 122c are arranged on the connecting rod 122b, a plurality of second through holes 21a are arranged on the middle frame fixing plate 21, the first through holes 122c and the second through holes 21a are arranged correspondingly, and the display device 1 further includes a third connecting structure 33, the third connecting structure 33 is arranged in the first through holes 122c and the second through holes 21a. By arranging the first fixed sliding block to include a connecting rod, a plurality of first through holes are arranged on the connecting rod, a plurality of second through holes are arranged on the middle frame fixing plate, and the third connecting structure is arranged in the first through holes and the second through holes, the middle frame fixing plate and the connecting rod can be fixed through the third connecting structure.

[0072] Specifically, the third connecting structure can be a third screw, and the third screw can be a half-threaded inner hexagonal screw or other screws.

[0073] Specifically, it can be understood that when the third screw is used to connect the middle frame fixing plate and the connecting rod, the first through hole and the second through hole can be threaded holes.

[0074] Specifically, it can be understood that since the connecting rod 122b covers the middle frame fixing plate 21, the second through hole 21a cannot be shown, Figure 1 the hole at the position of the first through hole 122c is marked as the second through hole 21a, but it can be understood that the second through hole 21a is arranged correspondingly with the first through hole 122c, the second through hole 21a is located below the first through hole 122c and on the middle frame fixing plate, and the shape and size of the second through hole 21a can be the same as those of the first through hole.

[0075] In some embodiments, as shown in Figure 1 , Figure 5 The driving assembly 12 further includes a rack 124, a transmission gear set 125, and a plurality of lead screws 126. The motor 121 includes a first motor 121a and a second motor 121b, which are symmetrically arranged on both sides of the rack. The transmission gear set 125 is arranged on the upper side of the rack 124, and the transmission gear set 125 is connected with the lead screws 126. Part of the lead screws 126 passes through the slider body 122a, and the other part of the lead screws 126 passes through the second fixed slider 123. By arranging the motor to include a first motor and a second motor, and symmetrically arranging the first motor and the second motor on both sides of the rack, the structure of the driving assembly can be more stable. The transmission gear set drives the lead screw, and the relative movement of the lead screw and the slider body drives the relative movement of the middle frame sliding plate and the middle frame fixed plate, thereby realizing the sliding and rolling of the display screen.
