[0035] The following refers to Figures 1 to 8 The display device of the present application is described in detail.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The display device according to an embodiment of the present invention includes a mounting bracket 100, a display screen 200, and a connecting module 300. The connecting module 300 includes a first connecting member 310, a second connecting member 320, a rotating shaft 330, and an elastic structure 340. The mounting bracket 100 and the display screen 200 are respectively connected to the first connecting member 310 and the second connecting member 320 via a rotating shaft 330. The first connecting member 310 is provided with a plurality of first connecting members 310 and 320 respectively distributed circumferentially around the rotating shaft 330. A protrusion 311 and a plurality of second protrusions 312 are provided. The second connector 320 is provided with a first slot 321 and a second slot 322. When the first slot 321 is inserted into one of the first protrusions 311, the second slot 322 is inserted into one of the second protrusions 312. The elastic structure 340 is provided on the rotating shaft 330 and is connected to at least one of the first connector 310 and the second connector 320. It is used to provide elastic force to keep the first slot 321 and the second slot 322 inserted into the first protrusion 311 and the second protrusion 312, respectively.

[0037] It should be noted that during the use of the display device, the user will rotate the display screen 200 relative to the mounting bracket 100 as needed to adjust the display angle of the display screen 200. During the process of the user rotating the display screen 200 relative to the mounting bracket 100, since the mounting bracket 100 and the display screen 200 are respectively connected to the first connector 310 and the second connector 320, the first connector 310 can rotate relative to the second connector 320.

[0038] For example, such as Figure 5 As shown, the second connector 320 is provided with two first slots 321 and two second slots 322, and the display screen 200 has a first preset state and a second preset state.

[0039] It can be understood that when the display screen 200 is rotated to the first preset state relative to the mounting frame 100, the first protrusion 311 can be clamped into one of the first clamping grooves 321, and the second protrusion 312 can be clamped into one of the second clamping grooves 322 at the same time, at this time, the display screen 200 can be stably in the first preset state, when the user drives the display screen 200 to continue to rotate relative to the mounting frame 100 to leave the first preset state, the user needs to exert more force to make the first protrusion 311 and the second protrusion 312 respectively leave the clamped first clamping groove 321 and the second clamping groove 322, so that the user has obvious hand feeling when driving the display screen 200 to enter and leave the first preset state; when the user drives the display screen 200 to continue to rotate to the second preset state, the first protrusion 311 can be clamped into the other first clamping groove 321, and the second protrusion 312 can be clamped into the other second clamping groove 322 at the same time, at this time, the display screen 200 can be stably in the second preset state, when the user drives the display screen 200 to rotate relative to the mounting frame 100 to leave the second preset state, the user needs to exert more force to make the first protrusion 311 and the second protrusion 312 respectively leave the clamped first clamping groove 321 and the second clamping groove 322, so that the user also has obvious hand feeling when driving the display screen 200 to enter and leave the second preset state.

[0040] It should be noted that for each more preset state of the display screen 200, the first clamping groove 321 and the second clamping groove 322 need to be provided on the second connecting piece 320. Correspondingly, the increase in the number of the first clamping groove 321 and the second clamping groove 322 will reduce the overall strength of the second connecting piece 320.

[0041] Based on the above problems, in some embodiments of the present application, the distance between the first clamping groove 321 and the axis of the rotating shaft 330 is less than the distance between the second clamping groove 322 and the axis of the rotating shaft 330. Figure 5

[0042] It can be understood that, due to the distance between the first clamping groove 321 and the axis of the rotating shaft 330 being less than the distance between the second clamping groove 322 and the axis of the rotating shaft 330, the first clamping groove 321 and the second clamping groove 322 can be staggered in the radial direction of the rotating shaft 330, and along the circumferential direction of the rotating shaft 330, there will be no second clamping groove 322 between any two adjacent first clamping grooves 321, and correspondingly, there will be no first clamping groove 321 between any two adjacent second clamping grooves 322, so that the first connecting piece 310 can have higher structural strength, thereby improving the service life of the display device of the present application.

[0043] ​In some embodiments of the utility model, connecting module 300 still includes mounting seat 350, mounting seat 350 is fixedly connected with display screen 200, second connecting piece 320 is arranged on mounting seat 350, mounting bracket 100 is fixedly connected with rotating shaft 330, and first connecting piece 310 is fixedly connected with rotating shaft 330 along the circumference direction of rotating shaft 330.

[0044] For example, as shown in Figures 2 to 5 Connecting module 300 still includes mounting seat 350, mounting seat 350 is arranged on the back of display screen 200, rotating shaft 330 extends along the left-right direction and is rotatably arranged on mounting seat 350, the cross-sectional shape of rotating shaft 330 is a waist type, first connecting piece 310 and second connecting piece 320 are respectively provided with first mounting hole 314 and second mounting hole 323, first mounting hole 314 is a waist shape, second mounting hole 323 is a circular type, rotating shaft 330 is respectively arranged in first mounting hole 314 and second mounting hole 323, second connecting piece 320 is rotatably arranged relative to rotating shaft 330, and second connecting piece 320 is fixedly connected with mounting seat 350, first connecting piece 310 is fixedly arranged relative to rotating shaft 330 along the circumference direction of rotating shaft 330, and rotating shaft 330 is fixedly connected with mounting bracket 100.

[0045] It can be understood that after the user applies a pushing force to display screen 200, mounting seat 350 can drive first connecting piece 310 to rotate relative to second connecting piece 320 under the drive of display screen 200, so as to realize the rotation of display screen 200 relative to mounting bracket 100.

[0046] In some embodiments of the utility model, referring to Figure 2 And Figure 6 Connecting module 300 still includes limiting piece 360 which is sleeved on rotating shaft 330, first limiting structure 361a and second limiting structure 361b are arranged on limiting piece 360, limiting part 351a is arranged on mounting seat 350, limiting part 351a can abut against first limiting structure 361a or second limiting structure 361b, so that display screen 200 can be limited to rotate within a certain angle range relative to mounting bracket 100.

[0047] It can be understood that, in the actual use of the display device, the display screen 200 does not need to rotate 360° relative to the mounting frame 100, on the contrary, if the display screen 200 is designed to be able to rotate 360° around the mounting frame, it will affect the stability of the display screen 200; in the display device of the embodiment, since the limiting piece 360 is provided with the first limiting structure 361a and the second limiting structure 361b, after the user drives the display screen 200 to rotate forward by a certain angle relative to the mounting frame 100, the limiting part 351a abuts against the first limiting structure 361a, at this time the user cannot continue to rotate the display screen 200 forward, after the user drives the display screen 200 to rotate reversely by a certain angle relative to the mounting frame 100, the limiting part 351a abuts against the second limiting structure 361b, at this time the user cannot continue to rotate the display screen 200 reversely, and then under the cooperation limiting of the first limiting structure 361a and the second limiting structure 361b, the display screen 200 in the display device of the utility model can rotate within a certain angle range.

[0048] In further embodiments of the utility model, with reference to Figure 6 , the limiting piece 360 is provided with an arc-shaped groove 361, and the limiting part 351a is arranged in the arc-shaped groove 361, and along the circumferential direction of the rotating shaft 330, the two groove walls of the arc-shaped groove 361 form the first limiting structure 361a and the second limiting structure 361b respectively.

[0049] It can be understood that the arc-shaped groove 361 has a simple structure and is convenient to manufacture.

[0050] In some embodiments of the utility model, with reference to Figure 2 and Figure 7 , the mounting seat 350 is provided with a clamping structure 370, the clamping structure 370 comprises a clamping piece 371, the circumferential side of the first connecting piece 310 is provided with a positioning groove 315 matched with the clamping piece 371, when the clamping piece 371 is clamped into the positioning groove 315, the first protrusion 311 is inserted into one of the first clamping grooves 321, and the second protrusion 312 is inserted into one of the second clamping grooves 322.

[0051] It should be noted that although the display screen 200 has a plurality of preset states, there is one preset state in which the display screen 200 is in the longest time, for example, when the display screen 200 is in the first preset state, the user can normally use the display screen 200 to watch a movie, when the display screen 200 is in the second preset state, the display screen 200 and the mounting frame 100 are in a folded state, which is beneficial to the storage and transportation of the display device.

[0052] It can be understood that in the display device of the embodiment, when the display screen 200 is in the first preset state, the clamping piece 371 is just clamped into the positioning groove 315, so that the display screen 200 can be more stably in the first preset state, when the user drives the display screen 200 to be separated from the first preset state, the user needs to exert greater force on the display screen 200, so that the first protrusion 311 is separated from the first clamping groove 321, and the second protrusion 312 is separated from the second clamping groove 322, and the clamping piece 371 is separated from the positioning groove 315.

[0053] In some embodiments of the utility model, the clamping structure 370 further includes elastic connecting pieces 372, the elastic connecting pieces 372 are connected with the mounting seat 350 and the clamping piece 371 respectively, and the elastic connecting pieces 372 are used to provide the elastic force for keeping the clamping piece 371 inserted into the positioning groove 315.

[0054] For example, as shown in the figure, Figure 7 The mounting seat 350 includes a seat body 351 and a mounting block 352, the rotating shaft 330 is rotatably arranged on the seat body 351, the mounting block 352 is arranged on the seat body 351 and located on the radial side of the rotating shaft 330, and the opposite ends of the elastic connecting pieces 372 are connected with the mounting block 352 and the clamping piece 371 respectively.

[0055] It can be understood that the arrangement of the elastic connecting pieces 372 enables the clamping piece 371 to be automatically inserted into the positioning groove 315 under the elastic force of the elastic connecting pieces 372 when the first mounting piece is rotated to face the clamping piece 371.

[0056] In some embodiments of the utility model, the rotating shaft 330 is sleeved with a nut 380, the elastic structure 340 is a spring, the spring is sleeved on the rotating shaft 330, and the opposite ends of the spring are respectively abutted with the nut 380 and the end of the first connecting piece 310 away from the second connecting piece 320.

[0057] For example, as shown in the figure, Figure 2 The nut 380 is sleeved on the rotating shaft 330 and is threadedly connected with the rotating shaft 330, the elastic structure 340 is a spring, the spring is sleeved on the rotating shaft 330 and located on the side of the first connecting piece 310 away from the second connecting piece 320, and the opposite ends of the spring are respectively connected with the first connecting piece 310 and the nut 380.

[0058] It can be understood that the spring has good elastic performance and a large deformation amount, and when the display screen 200 is separated from the preset state, the spring can be compressed to avoid the first connecting piece 310, so that the first protrusion 311 on the first connecting piece 310 can be smoothly separated from the first clamping groove 321 on the second connecting piece 320, and the second protrusion 312 on the first connecting piece 310 can be smoothly separated from the second clamping groove 322 on the second connecting piece 320.

[0059] In some embodiments of the present application, referring to Figure 4 , the end of the first connecting member 310 away from the second connecting member 320 is provided with a receiving groove 313 for accommodating the spring.

[0060] It can be understood that by providing the receiving groove 313 on the first connecting member 310, one end of the spring can be accommodated in the receiving groove 313, and the groove wall of the receiving groove 313 can limit the spring in the radial direction of the rotating shaft 330 to reduce the deformation of the spring in the radial direction of the rotating shaft 330.

[0061] In some embodiments of the present application, referring to Figure 1 and Figure 8 , the mounting bracket 100 includes a base 110 and a connecting rod 120, one end of the connecting rod 120 is hingedly connected to the base 110, and the other end of the connecting rod 120 is in driving connection with the first connecting member 310.

[0062] It can be understood that the provision of the connecting rod 120 allows the display screen 200 to have a certain distance from the base 110. When the display device of the present application is in use, the base 110 is placed on the desktop and supports the display screen 200. The provision of the connecting rod 120 allows the display screen 200 to have a higher height to improve the user's experience. At the same time, the provision of the connecting rod 120 allows the display screen 200, the connecting rod 120 and the base 110 to be folded in the shape of a "Z" when the display device of the present application is stored and transported. The display device of the present application is more convenient to fold and has a smaller size after folding.

[0063] In further embodiments of the present application, the mounting bracket 100 includes two connecting rods 120, and the two connecting rods 120 are respectively arranged on opposite sides of the base 110.

[0064] For example, as shown in Figure 1 and Figure 8 , the mounting bracket 100 includes two connecting rods 120, and two connecting modules 300 are provided. The two connecting rods 120 are respectively in driving connection with the first connecting members 310 of the two connecting modules 300, and the two connecting rods 120 are respectively located on the left and right sides of the base 110 and are respectively in rotary connection with the left and right ends of the base 110.

[0065] It can be understood that in the display device of the present application, the base 110 is arranged between the two connecting rods 120. After the display device of the present application is folded, the base 110 can be located exactly between the two connecting rods 120 and can be attached to the back of the display screen 200, so that the display device of the present application can have a smaller size after folding.

[0066] Specifically, the specific connection form between the connecting rod 120 and the base 110 is referred to the connection form between the connecting rod 120 and the display screen 200.

[0067] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
