[0048] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the drawings, and detailed descriptions of the drawings are omitted for brevity. Further, the drawings are diagrammatic, schematic, and not necessarily drawn to scale.

[0049] The terms "one", "a", "the", "said", and "at least one" are used to indicate the existence of one or more elements / components / etc.; the terms "include" and "has" are used to indicate an open-ended inclusion in such that additional elements / components / etc. can be present in addition to those listed; the terms "first", "second", and "third", etc. are used only as labels, not as a limitation on the number of objects.

[0050] The first direction X, the second direction Y and the third direction Z herein are directions perpendicular to each other to form a spatial orthogonal coordinate system.

[0051] The display device provided by the embodiments of the present disclosure can be a mobile phone, a television, a tablet computer, a vehicle-mounted display device, an aircraft display device, or other types of display devices. For example, when the display device is a vehicle-mounted television or an armrest screen, the display device can be used by passengers to watch videos, and can also be used by passengers to turn on air conditioners, refrigerators, vehicle windows, or adjust seats, etc. The display device has the advantages of convenient disassembly and low cost.

[0052] Referring to Figures 1-4 The display device can include a base 1, a rotating frame 2, a rotating assembly 3, a display panel 4, and a locking assembly 5. The base 1 includes a receiving cavity having an open end and a closed end arranged opposite to each other. The rotating frame 2 is arranged on the base 1 and is rotatably connected to the base 1 through the rotating assembly 3. The display panel 4 is detachably arranged on the rotating frame 2. The locking assembly 5 is arranged on the base 1 and is switchable between a locked state and an unlocked state. In the locked state, the locking assembly 5 can block the rotation of the rotating frame 2. In the unlocked state, the rotating frame 2 can rotate.

[0053] In this way, when the display panel 4 needs to be disassembled, the locking assembly 5 can be switched from the locked state to the unlocked state. When the locking assembly 5 is switched to the unlocked state, the rotating frame 2 is rotated, and the display panel 4 is synchronously rotated by the rotating frame 2, so that the display panel 4 passes through the open end and is located outside the receiving cavity. A person can take the display panel 4 off the rotating frame 2, so as to facilitate the disassembly of the display panel 4 and improve the disassembly efficiency of the display panel 4.

[0054] When it is necessary to install the display panel 4, a person detachably installs the display panel 4 on the rotating frame 2, and then pushes the display panel 4, so that the rotating frame 2 reversely rotates, the display panel 4 synchronously rotates with the rotating frame 2, and the locking assembly 5 is in the locked state, so as to lock the rotating frame 2 and the display panel 4 in the accommodating cavity, thereby facilitating the installation of the display panel 4 and improving the installation efficiency of the display panel 4.

[0055] In an embodiment of the present disclosure, referring to Figures 1-4 , the rotating frame 2 has a main body part, the main body part is capable of rotating between a first position and a second position, the first position is located on a side away from the closed end of the second position. The rotating assembly 3 is used for applying a rotating force to the main body part towards the first position. The locking assembly 5 is connected with the main body part; in the locked state, the locking assembly 5 can block the main body part from rotating towards the first position; in the unlocked state, the main body part is capable of rotating between the first position and the second position.

[0056] Thus, when it is necessary to detach the display panel 4, the locking assembly 5 can be switched from the locked state to the unlocked state, when the locking assembly 5 is switched to the unlocked state, the rotating assembly 3 applies a rotating force to the main body part towards the first position, so that the main body part rotates towards the first position, the main body part drives the display panel 4 to synchronously rotate, and the main body part rotates to the first position, so that the display panel 4 is located outside the accommodating cavity through the open end, and a person can take the display panel 4 off from the main body part, thereby facilitating the detachment of the display panel 4 and improving the detachment efficiency of the display panel 4.

[0057] When it is necessary to install the display panel 4, a person detachably installs the display panel 4 on the main body part, and then pushes the display panel 4, so that the main body part rotates towards the second position, the display panel 4 synchronously rotates with the main body part, and the locking assembly 5 is in the locked state, so as to lock the main body part and the display panel 4 in the accommodating cavity, thereby facilitating the installation of the display panel 4 and improving the installation efficiency of the display panel 4.

[0058] In an embodiment of the present disclosure, when the main body part is located at the first position, at least part of the display panel 4 is located outside the accommodating cavity. When the main body part is located at the second position, the display panel 4 is located in the accommodating cavity.

[0059] In an embodiment of the present disclosure, the base 1 can include a rear cover and a side plate arranged around the rear cover, the rear cover and the side plate form the accommodating cavity, and the rear cover can be integrally formed with the side plate. The side plate on a side close to the rear cover is the closed end, and a side of the side plate away from the rear cover is the open end.

[0060] In an embodiment of the present disclosure, the display panel 4 can be a Light Emitting Diode (LED) display panel 4, an Organic Light-Emitting Diode (OLED) display panel 4, a Quantum Dot Light Emitting Diodes (QLED) display panel 4, or other types of display panels 4.

[0061] In an embodiment of the present disclosure, referring to Figures 5-10 , the locking assembly 5 comprises a fitting piece 51 and a locking piece 52. The fitting piece 51 is fixedly connected to the side of the main body part away from the display panel 4, and the fitting piece 51 has a groove 511. The locking piece 52 penetrates the closed end and extends into the accommodating cavity. The locking piece 52 has a locking hook 521 at one end of the accommodating cavity, and the locking hook 521 is movably arranged in the inner cavity of the locking piece 52. When the locking assembly 5 is in the locked state, the locking hook 521 hooks with the side wall of the groove 511 away from the display panel 4. When the locking assembly 5 is in the unlocked state, the locking hook 521 is disengaged from the groove 511. In this way, when the main body part is in the second position, the display panel 4 can be pushed inward by hand, so that the end of the fitting piece 51 away from the display panel 4 applies a force to the locking piece 52, thereby driving the locking hook 521 to move until the locking hook 521 is disengaged from the groove 511, so as to make the locking assembly 5 in the unlocked state. When the main body part is in the first position, the display panel 4 can be pushed inward by hand, so that the end of the fitting piece 51 away from the display panel 4 extends into the inner cavity of the locking piece 52 and applies a force to the locking piece 52, thereby driving the locking hook 521 to move until the locking hook 521 is located in the groove 511 and hooks with the side wall of the groove 511 away from the display panel 4, so as to make the locking assembly 5 in the locked state.

[0062] It should be noted that in the drawings (for example Figure 9 , Figure 10 ) of the present disclosure, the structure for driving the rotation and resetting of the locking hook 521 is not shown in the drawings. The inside of the locking piece 52 can be provided with a rotating shaft, an elastic resetting piece, or the like, to realize the rotation and resetting of the locking hook 521. In other words, the drawings of the present disclosure are only schematic drawings. Although the internal structure of the locking piece 52 is shown as a solid structure, the inside of the locking piece 52 is also provided with a rotating shaft, an elastic resetting piece (not shown in the drawings), or the like, to realize the rotation and resetting of the locking hook 521.

[0063] In an embodiment of the present disclosure, the locking hook 521 can rotate around a straight line where the first direction X is located. When the fitting piece 51 presses the locking piece 52, the locking hook 521 can rotate in a direction away from the fitting piece 51 to realize unlocking of the locking hook 521. When the fitting piece 51 presses the locking piece 52 again, the locking hook 521 can rotate in a direction close to the fitting piece 51 to realize locking of the locking hook 521.

[0064] In an embodiment of the present disclosure, referring to Figure 6 , Figure 8 , Figure 9 , Figure 10 , the recess 511 is provided with a protruding part 512, the protruding part 512 protrudes towards the locking hook 521, and the distance from the surface of the locking piece 52 close to the display panel 4 to the bottom of the groove 511 decreases in sequence from close to the display panel 4 to away from the display panel 4. In other words, the protruding part 512 is arranged obliquely. The protruding part 512 and the side of the recess 511 away from the display panel 4 form a containing cavity, and the locking hook 521 is located in the containing cavity in the locking state. In this way, in the unlocking process of the locking hook 521, the locking hook 521 can slide along the protruding part 512 to facilitate smooth unlocking of the locking hook 521 and reduce the possibility of the locking hook 521 being stuck.

[0065] In an embodiment of the present disclosure, referring to Figure 6 and Figure 8 , the number of the protruding part 512 can be two, and the two protruding parts 512 are distributed along the first direction X. In this way, in the unlocking process of the locking hook 521, the locking hook 521 can slide on the two protruding parts 512, and the two protruding parts 512 can jointly press the locking hook 521 to facilitate smooth unlocking of the locking hook 521 and further reduce the possibility of the locking hook 521 being stuck.

[0066] In an embodiment of the present disclosure, referring to Figure 7 , Figure 9 , Figure 10 , the locking piece 52 is provided with a first limiting part 522 and a second limiting part 523, the first limiting part 522 and the second limiting part 523 are distributed along the length direction of the locking piece 52, the first limiting part 522 is located in the containing cavity, the second limiting part 523 is located outside the containing cavity, there is a gap between the first limiting part 522 and the second limiting part 523, and the closed end abuts between the first limiting part 522 and the second limiting part 523. In this way, through the first limiting part 522 and the second limiting part 523, the locking piece 52 is fixed on the base 1, which improves the stability and reliability of the display device.

[0067] In an embodiment of the present disclosure, the first limiting part 522 can be a ring-shaped boss fixedly connected to the side of the locking piece 52 close to the display panel 4. The second limiting part 523 includes two clamping blocks distributed on the two sides of the locking piece 52 along the first direction X. The clamping blocks and the ring-shaped boss have a gap therebetween, so that the closed end is clamped between the gap, and the locking piece 52 is facilitated to be fixed on the base 1.

[0068] In an embodiment of the present disclosure, the two clamping blocks are flexible and can rotate towards each other. During the installation of the locking piece 52, the two clamping blocks can be pressed by hand, so that the two clamping blocks are close to each other, and then the end of the locking piece 52 away from the first limiting part 522 is inserted through the closed end until the base 1 is clamped between the first limiting part 522 and the clamping blocks, and the locking piece 52 is facilitated to be disassembled and maintained.

[0069] In an embodiment of the present disclosure, the locking piece 52 can be provided with a plurality of process holes along the length direction thereof, so as to reduce the weight of the locking piece 52 and reduce the manufacturing cost of the locking piece 52.

[0070] In an embodiment of the present disclosure, referring to Figure 3 , Figure 4 , Figure 5 , the rotating frame 2 further includes an auxiliary part. The main part and the auxiliary part are integrally connected, and the main part and the auxiliary part are distributed along the third direction Z.

[0071] The rotating assembly 3 includes a rotating shaft 31 and at least one elastic member 32. The rotating shaft 31 is rotatably connected to the critical position of the main part and the auxiliary part, and the axis of the rotating shaft 31 extends along the first direction X. The elastic member 32 abuts against the base 1 and the main part respectively, and the elastic member 32 applies a force to the main part to rotate to the first position. In this way, the rotating shaft 31 can realize the rotating connection between the rotating frame 2 and the base 1, and the elastic member 32 can apply a force to the main part to rotate to the first position, so as to drive the display panel 4 to rotate to the first position.

[0072] It should be noted that the critical position of the main part and the auxiliary part is the connection position of the main part and the auxiliary part. Since the rotating shaft 31 is arranged at the critical position of the main part and the auxiliary part, when the rotating frame 2 rotates, the main part rotates close to or away from the closed end, and the auxiliary part is arranged away from or close to the closed end.

[0073] In an embodiment of the present disclosure, the rotating frame 2 can not be provided with the auxiliary part, that is, the rotating frame 2 only has the main part, and the rotating shaft 31 can be arranged at the edge of the main part to realize the rotating connection between the main part and the base 1.

[0074] In an embodiment of the present disclosure, the number of elastic members 32 can be two, three, four, etc., and the plurality of elastic members 32 can be distributed along the axial direction of the rotating shaft 31. Referring to Figure 5 , the elastic member 32 can be a torsion spring having two force applying ends, the torsion spring is coaxially sleeved on the rotating shaft 31, and one force applying end abuts against the base 1 and the other force applying end abuts against the side of the main body part away from the display panel 4, so as to apply a force to the main body part to rotate to the first position in the unlocked state, so as to facilitate the display panel 4 to automatically pop out from the accommodating cavity. In other embodiments of the present disclosure, the elastic member 32 can be a "V"-shaped spring sheet.

[0075] In an embodiment of the present disclosure, referring to Figure 5 , Figure 9 , Figure 11 , the rotating shaft 31 is coaxially sleeved with a damping part 33, the damping part 33 is fixedly connected with the rotating shaft 31, and the damping part 33 contacts the side of the rotating frame 2 away from the display panel 4. The side of the rotating frame 2 away from the display panel 4 is provided with a damping shell 21, the damping part 33 is located in the damping shell 21, and the inner wall of the damping shell 21 is provided with a first damping strip 22, the first damping strip 22 contacts the peripheral wall of the damping part 33. In this way, during the rotation of the rotating frame 2 along the rotating shaft 31, the outer peripheral wall of the damping part 33 contacts the side of the rotating frame 2 away from the display panel 4, and at the same time, the outer peripheral wall of the damping part 33 contacts the first damping strip 22, so that the damping part 33 has a friction force with the rotating frame 2 and the first damping strip 22 respectively, facilitating the main body part to rotate stably.

[0076] In an example, the shape of the damping part 33 can be columnar, and the damping part 33 can be fixedly connected with the rotating shaft 31 by bonding, clamping or key connection. The shape of the damping shell 21 can be "U"-shaped, and the damping shell 21 can wrap the damping part 33. The number of the first damping strips 22 can be multiple, for example, the number of the first damping strips 22 can be two, three, four, etc., and the plurality of first damping strips 22 can be uniformly distributed along the circumferential direction of the damping shell 21, and the end of the first damping strip 22 away from the damping shell 21 contacts the outer peripheral wall of the damping part 33. The first damping strip 22 can extend along the first direction X, so as to provide damping when the main body part rotates.

[0077] In an embodiment of the present disclosure, referring to Figure 9 and Figure 11The side of the rotating frame 2 away from the display panel 4 can be provided with a second damping strip 23, the number of the second damping strip 23 can be multiple, and the material of the second damping strip 23 can be the same as that of the first damping strip 22, for example, both can be rubber. The multiple second damping strips 23 are distributed along the third direction Z, so that part of the second damping strips 23 are located in the main body part, and the remaining part of the second damping strips 23 are located in the auxiliary part; the second damping strips 23 extend along the first direction X, and the second damping strips 23 are in contact with the peripheral wall of the damping part 33, so as to provide damping for the main body part during rotation.

[0078] In an embodiment of the present disclosure, the base 1 is provided with a protective shell, the protective shell can be located at the closed end, and the damping shell 21 is located in the protective shell, so as to protect the damping shell 21 and prolong the service life of the damping shell 21.

[0079] In an embodiment of the present disclosure, referring to Figure 3 , Figure 4 The display device further comprises a guide assembly 6. The guide assembly 6 comprises at least one guide plate 61, for example, the number of guide plates 61 can be two, three, four, etc., the multiple guide plates 61 are distributed along the first direction X, the guide plates 61 extend along the second direction Y, and the side of the guide plates 61 away from the display panel 4 can be fixedly connected by bonding, integral connection, clamping, etc. The closed end is provided with a guide groove 11, the guide groove 11 penetrates through the closed end, and one end of the guide plate 61 away from the display panel 4 extends out of the accommodating cavity through the guide groove 11. The size of the guide plate 61 in the third direction Z is smaller than the size of the guide groove 11 in the third direction Z. In this way, the guide plate 61 can guide the main body part to rotate around the rotating shaft 31 to the first position, and improve the stability of the rotation of the main body part.

[0080] In an embodiment of the present disclosure, referring to Figure 9 One end of the guide plate 61 away from the display panel 4 is provided with a stop block 62, and the stop block 62 can be integrally connected with the guide plate 61. When the main body part is located at the first position, the stop block 62 abuts against the side of the closed end away from the display panel 4, in other words, the stop block 62 cannot pass through the guide groove 11. In this way, when the main body part rotates to the first position, the stop block 62 can abut against the side of the closed end away from the display panel 4, so as to prevent the main body part from continuing to rotate, which is beneficial to control the angle of rotation of the main body part.

[0081] In an embodiment of the present disclosure, referring to Figure 4The base 1 has buffer strips 12 on its side walls. There can be multiple buffer strips 12, such as two, three, or four. These multiple buffer strips 12 can be distributed circumferentially along the inner side walls of the base 1. Specifically, multiple buffer strips 12 can be located on two inner side walls of the base 1 distributed along a first direction X, extending along a second direction Y. The buffer strips 12 contact the side walls of the rotating frame 2, and are made of rubber. Thus, during the rotation of the main body towards the first position, the buffer strips 12 provide cushioning force to the main body, allowing it to rotate more smoothly.

[0082] In one embodiment of this disclosure, see Figure 5 , Figure 9 A first magnet 24 is provided on the side of the rotating frame 2 away from the display panel 4, and a second magnet 41 is provided on the side of the display panel 4 closer to the rotating frame 2. The first magnet 24 and the second magnet 41 are arranged opposite to each other, and their polarities are opposite. The first magnet can be attached to the rotating frame 2 by snapping or bonding, and the second magnet 41 can be attached to the display panel 4 by snapping or bonding. In this way, the attraction between the first magnet 24 and the second magnet 41 facilitates the connection between the display panel 4 and the rotating frame 2 during the rotation of the display panel 4 driven by the rotating frame 2, preventing the display panel 4 from falling off the rotating frame 2 and improving the reliability of the display device.

[0083] In one embodiment of this disclosure, there are multiple first magnets 24 and second magnets 41, and the number of first magnets 24 and second magnets 41 is the same. For example, the number of first magnets 24 and second magnets 41 can be two, three, four, five, etc.

[0084] In one embodiment of this disclosure, see Figure 3 A buffer pin 13 may be provided on the side of the base 1 away from the display panel 4.
