[0065] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0066] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0067] In this paper, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular directions to form a spatial rectangular coordinate system.

[0068] This disclosure provides a display device. The display device can be a mobile phone, television, tablet computer, vehicle-mounted display device, aircraft-mounted display device, or other types of display devices. For example, when the display device is a vehicle-mounted television or armrest screen, it allows passengers to watch videos and also allows them to operate functions such as turning on the air conditioner, refrigerator, windows, or adjusting the seat. This display device has advantages such as easy disassembly and low cost.

[0069] See Figures 1-5 The display device may include a base 1, a rotating frame 2, a rotating assembly 3, a display panel 4, a locking assembly 5, and a clamping assembly 7. The base 1 includes a receiving cavity with an open end and a closed end disposed opposite to each other. The rotating frame 2 is disposed on the base 1 and rotatably connected to the base 1 via the rotating assembly 3. The display panel 4 is detachably disposed on the rotating frame 2. The locking assembly 5 is disposed on the base 1 and can switch between a locked state and an unlocked state; in the locked state, the locking assembly 5 can prevent the rotating frame 2 from rotating to a first position; in the unlocked state, the rotating frame 2 can rotate. The clamping assembly 7 is disposed on the rotating frame 2 and passes through the rotating frame 2; the clamping assembly 7 is detachably connected to the display panel 4.

[0070] Thus, when it is necessary to disassemble the display panel 4, the locking component 5 can be switched from the locked state to the unlocked state. When the locking component 5 is switched to the unlocked state, the rotating frame 2 will drive the display panel 4 to rotate synchronously until the display panel 4 passes through the open end and is located outside the receiving cavity. The display panel 4 can then be removed from the rotating frame 2 by hand, facilitating the disassembly of the display panel 4 and improving the disassembly efficiency. During this process, the clamping component 7 gradually disengages from the display panel 4. When the rotating frame 2 stops, the clamping component 7 is completely disengaged from the display panel 4, reducing the possibility of the display panel 4 falling off during rotation and improving the reliability of the display device.

[0071] When it is necessary to install the display panel 4, the operator manually detaches the display panel 4 onto the rotating frame 2, then pushes the display panel 4, causing the rotating frame 2 to rotate in the opposite direction. The display panel 4 also rotates synchronously with the rotating frame 2 until the rotating frame stops rotating. At this point, the locking component 5 is in a locked state, securing the rotating frame 2 and the display panel 4 into the receiving cavity, facilitating the installation of the display panel 4 and improving the installation efficiency. During this process, the clamping component 7 gradually connects to the display panel 4. When the rotating frame 2 stops rotating, the clamping component 7 is fully connected to the display panel 4, making the operation convenient and quick.

[0072] In one embodiment of this disclosure, see Figures 1-5The rotating frame 2 has a main body that can rotate between a first position and a second position, the first position being located on the side of the second position away from the closed end. A rotating assembly 3 applies a force to the main body to rotate it towards the first position. A locking assembly 5 is connected to the main body; in the locked state, the locking assembly 5 prevents the main body from rotating towards the first position; in the unlocked state, the main body can rotate between the first and second positions. A clamping assembly 7 is disposed on the main body and passes through it; when the main body is in the first position, the clamping assembly 7 is disengaged from the display panel 4; when the main body is in the second position, the clamping assembly 7 is connected to the display panel 4.

[0073] Thus, when it is necessary to disassemble the display panel 4, the locking component 5 can be switched from the locked state to the unlocked state. When the locking component 5 is switched to the unlocked state, the rotating component 3 will apply a force to the main body to rotate towards the first position, causing the main body to rotate towards the first position. The main body drives the display panel 4 to rotate synchronously until the main body rotates to the first position, so that the display panel 4 passes through the open end and is located outside the receiving cavity. The display panel 4 can then be removed from the main body by hand, which facilitates the disassembly of the display panel 4 and improves the disassembly efficiency of the display panel 4. During the rotation of the main body towards the first position, the clamping component 7 gradually disengages from the display panel 4. When the main body reaches the first position, the clamping component 7 is completely disengaged from the display panel 4, reducing the possibility of the display panel 4 falling off during rotation and improving the reliability of the display device.

[0074] When it is necessary to install the display panel 4, the display panel 4 is detachably installed on the main body by hand. Then, the display panel 4 is pushed, causing the main body to rotate to the second position. The display panel 4 also rotates synchronously with the main body until the main body rotates to the second position. At this point, the locking component 5 is locked, securing the main body and the display panel 4 into the receiving cavity, thus facilitating the installation of the display panel 4 and improving the installation efficiency. During the rotation of the main body to the second position, the clamping component 7 gradually connects to the display panel 4. When the main body reaches the second position, the clamping component 7 is fully connected to the display panel 4, making the operation convenient and quick.

[0075] In one embodiment of this disclosure, when the main body is in the first position, at least a portion of the display panel 4 is located outside the receiving cavity. When the main body is in the second position, the display panel 4 is located inside the receiving cavity. In other embodiments of this disclosure, when the main body is in the second position, the display panel 4 may not be in the receiving cavity.

[0076] In one embodiment of this disclosure, the base 1 may include a rear cover and a side plate disposed around the rear cover, the rear cover and the side plate forming the receiving cavity, and the rear cover may be integrally formed with the side plate. The side of the side plate near the rear cover is the closed end, and the side of the side plate away from the rear cover is the open end.

[0077] In one embodiment of this disclosure, the display panel 4 may be a light-emitting diode (LED) display panel 4, an organic light-emitting diode (OLED) display panel 4, a quantum dot light-emitting diode (QLED) display panel 4, or other types of display panels 4.

[0078] In one embodiment of this disclosure, see Figure 5 , Figures 8-11 The locking assembly 5 includes a mating member 51 and a locking member 52. The mating member 51 is fixedly connected to the side of the main body away from the display panel 4, and has a groove 511. The locking member 52 extends through the closed end and into the receiving cavity. One end of the locking member 52 located in the receiving cavity has a locking hook 521, which is movably disposed within the inner cavity of the locking member 52. When the locking assembly 5 is in the locked state, the locking hook 521 engages 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 disengages from the groove 511. Thus, when the main body is in the second position, a hand can push the display panel 4 inward, causing the end of the mating member 51 away from the display panel 4 to apply force to the locking member 52, thereby driving the locking hook 521 to move until it disengages from the groove 511, allowing the locking assembly 5 to be in the unlocked state. When the main body is in the first position, a person can push the display panel 4 inward, so that the end of the mating part 51 away from the display panel 4 extends into the inner cavity of the locking part 52 and applies force to the locking part 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 that the locking assembly 5 is in the locked state.

[0079] It should be noted that in the accompanying drawings of this disclosure (e.g.) Figure 11 , Figure 12 The structure for driving the lock hook 521 to rotate and reset is not shown in the figure. The locking member 52 may have a rotating shaft, an elastic reset member, or other structures inside to achieve the rotation and reset of the lock hook 521. In other words, the figures in this disclosure are only schematic diagrams. Although the internal structure of the locking member 52 is shown as a solid structure, it also has a rotating shaft, an elastic reset member (not shown in the figure), and other structures inside to achieve the rotation and reset of the lock hook 521.

[0080] In one embodiment of this disclosure, the locking hook 521 can rotate about the line containing the first direction X. When the mating member 51 presses against the locking member 52, the locking hook 521 can rotate away from the mating member 51 to unlock the locking hook 521. When the mating member 51 presses against the locking member 52 again, the locking hook 521 can rotate towards the mating member 51 to lock the locking hook 521.

[0081] In one embodiment of this disclosure, see Figure 8 , Figures 10-12 The groove 511 contains a protrusion 512 that protrudes towards the locking hook 521. The distance from the surface of the protrusion 512 near the locking member 52 to the bottom of the groove 511 decreases progressively from near the display panel 4 to far away from the display panel 4. In other words, the protrusion 512 is inclined. A receiving cavity is formed between the protrusion 512 and the side of the groove 511 away from the display panel 4. In the locked state, the locking hook 521 is located within the receiving cavity. Thus, during the unlocking process, the locking hook 521 can slide along the protrusion 512, facilitating smooth unlocking and reducing the possibility of the locking hook 521 getting stuck.

[0082] In one embodiment of this disclosure, see Figure 8 and Figure 10 The number of protrusions 512 can be two, and the two protrusions 512 are distributed at intervals along the first direction X. In this way, during the unlocking process of the lock hook 521, the lock hook 521 can slide on the two protrusions 512, and the two protrusions 512 can jointly squeeze the lock hook 521 to move, so as to facilitate the smooth unlocking of the lock hook 521 and further reduce the possibility of the lock hook 521 getting stuck.

[0083] In one embodiment of this disclosure, see Figure 9 , Figure 11 , Figure 12 The locking member 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 at intervals along the length direction of the locking member 52. The first limiting part 522 is located inside the receiving cavity, and the second limiting part 523 is located outside the receiving cavity. There is a gap between the first limiting part 522 and the second limiting part 523, and the closed end abuts against the gap between the first limiting part 522 and the second limiting part 523. In this way, the first limiting part 522 and the second limiting part 523 facilitate the fixing of the locking member 52 to the base 1, thereby improving the stability and reliability of the display device.

[0084] In one embodiment of this disclosure, the first limiting part 522 may be an annular boss, which is fixedly connected to the side of the locking member 52 near the display panel 4. The second limiting part 523 includes two locking blocks, which are distributed on both sides of the locking member 52 along the first direction X. There is a gap between the locking blocks and the annular boss, so that the closed end can be engaged in the gap, which is beneficial for fixing the locking member 52 to the base 1.

[0085] In one embodiment of this disclosure, the two locking blocks are elastic and can rotate towards each other. During the installation of the locking member 52, a person can press the two locking blocks together to bring them closer together, and then pass the end of the locking member 52 away from the first limiting part 522 through the closed end until the base 1 is engaged between the first limiting part 522 and the locking block, which facilitates the disassembly and maintenance of the locking member 52.

[0086] In one embodiment of this disclosure, the locking member 52 may be provided with a plurality of process holes along its length to reduce the weight of the locking member 52 and reduce the manufacturing cost of the locking member 52.

[0087] In one embodiment of this disclosure, see Figure 3 , Figure 4 , Figure 5 The rotating frame 2 also includes an auxiliary part. The main body and the auxiliary part are integrally connected and are distributed along the third direction Z.

[0088] The rotating assembly 3 includes a rotating shaft 31 and at least one first elastic element 32. The rotating shaft 31 is rotatably connected to the critical position between the main body and the auxiliary part, and its axis extends along a first direction X. The first elastic element 32 abuts against both the base 1 and the main body, applying a force to the main body to rotate it towards a first position. Thus, the rotating shaft 31 enables the rotating frame 2 to be rotatably connected to the base 1, and the first elastic element 32 applies a force to the main body to rotate it towards the first position, thereby allowing the main body to drive the display panel 4 to rotate towards the first position.

[0089] It should be noted that the critical position between the main body and the auxiliary part is the connection position between the main body and the auxiliary part. Since the rotating shaft 31 is located at the critical position between the main body and the auxiliary part, when the rotating frame 2 rotates, the main body rotates closer to or further away from the closed end, and the auxiliary part is located further away from or closer to the closed end.

[0090] In one embodiment of this disclosure, the rotating frame 2 may not have an auxiliary part, that is, the rotating frame 2 only has a main body, and the rotating shaft 31 may be located at the edge of the main body to realize the rotational connection between the main body and the base 1.

[0091] In one embodiment of this disclosure, the number of first elastic elements 32 can be two, three, four, etc., and multiple first elastic elements 32 can be distributed along the axial direction of the rotation shaft 31. See also Figure 5 The first elastic element 32 can be a torsion spring with two force-applying ends. The torsion spring is coaxially sleeved on the rotating shaft 31, with one force-applying end abutting against the base 1 and the other force-applying end abutting against the side of the main body away from the display panel 4. This allows the torsion spring to apply a force to the main body to rotate towards the first position when in the unlocked state, so that the display panel 4 can automatically pop out of the receiving cavity. In some other embodiments of this disclosure, the first elastic element 32 can be a "V"-shaped spring sheet.

[0092] In one embodiment of this disclosure, see Figure 5 , Figure 11 , Figure 13 A damping part 33 is coaxially sleeved on the rotating shaft 31 and fixedly connected to the rotating shaft 31. The damping part 33 contacts the side of the rotating frame 2 away from the display panel 4. A damping shell 21 is provided on the side of the rotating frame 2 away from the display panel 4, and the damping part 33 is located inside the damping shell 21. A first damping strip 22 is provided on the inner wall of the damping shell 21, and the first damping strip 22 contacts the peripheral wall of the damping part 33. Thus, 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 friction with the rotating frame 2 and the first damping strip 22 respectively, which facilitates the smooth rotation of the main body.

[0093] In one example, the damping portion 33 can be cylindrical in shape and can be fixedly connected to the rotating shaft 31 by means of bonding, snap-fitting, or keying. The damping shell 21 can be U-shaped and can enclose the damping portion 33. There can be multiple first damping strips 22, such as two, three, or four. These first damping strips 22 can be evenly distributed along the circumference of the damping shell 21, with one end of each first damping strip 22 away from the damping shell 21 contacting the outer peripheral wall of the damping portion 33. The first damping strips 22 can extend along a first direction X to provide damping when the main body rotates.

[0094] In one embodiment of this disclosure, see Figure 11 , Figure 13A second damping strip 23 may be provided on the side of the rotating frame 2 away from the display panel 4. There may be multiple second damping strips 23, and their material may be the same as that of the first damping strip 22, for example, rubber. Multiple second damping strips 23 are distributed at intervals along a third direction Z, such that some of the second damping strips 23 are located in the main body and the remaining second damping strips 23 are located in the auxiliary part. The second damping strips 23 extend along a first direction X and contact the peripheral wall of the damping part 33, thereby providing damping to the main body during rotation.

[0095] In one embodiment of this disclosure, the base 1 has a protective shell, which can be located at the closed end, and the damping shell 21 is located inside the protective shell, so as to protect the damping shell 21 and improve the service life of the damping shell 21.

[0096] In one embodiment of this disclosure, see Figure 3 , Figure 4 The display device also includes a guide assembly 6. The guide assembly 6 includes multiple guide plates 61, for example, two, three, four, etc. The multiple guide plates 61 are spaced apart along a first direction X and extend along a second direction Y. The guide plates 61 are fixedly connected to the side of the main body away from the display panel 4 by means of adhesive bonding, integral connection, snap-fit, etc. A guide groove 11 is provided at the closed end, extending through the closed end. The end of the guide plate 61 away from the display panel 4 extends out of the receiving cavity through the guide groove 11. The dimension of the guide plate 61 in the third direction Z is smaller than the dimension of the guide groove 11 in the third direction Z. Thus, the guide plate 61 can guide the main body to rotate around the rotation axis 31 to the first position, improving the stability of the main body's rotation process.

[0097] In one embodiment of this disclosure, see Figure 3 , Figure 4 , Figure 5 , Figure 11 A stop 62 is provided at the end of the guide plate 61 away from the display panel 4, and the stop 62 can be integrally connected to the guide plate 61. When the main body is in the first position, the stop 62 abuts against the side of the closed end away from the display panel 4; in other words, the stop 62 cannot pass through the guide groove 11. Thus, when the main body rotates to the first position, the stop 62 can abut against the side of the closed end away from the display panel 4, thereby preventing the main body from continuing to rotate and facilitating control over the angle at which the main body can rotate.

[0098] In one embodiment of this disclosure, see Figures 3-5 , Figures 14-18The closed end is provided with an opening 12, which is shaped like an "I". The opening 12 is located between two guide grooves 11, and the side wall of the opening 12 is provided with a guide slope 14. The dimension of the guide slope 14 in the third direction Z decreases from near the display panel 4 to far away from the display panel 4; in other words, the height of the guide slope 14 decreases from near the display panel 4 to far away from the display panel 4.

[0099] The clamping assembly 7 includes a mounting base 71, a gripper 72, and a second elastic member 73. The mounting base 71 is located on the side of the main body away from the display panel 4 and passes through the opening 12. The gripper 72 is rotatably connected to the mounting base 71 and passes through the opening 12; the gripper 72 contacts the guide ramp 14, passes through the main body, and is detachably connected to the display panel 4. The second elastic member 73 is connected to the mounting base 71 and applies a force to the gripper 72 to rotate toward the display panel 4. In one example, the second elastic member 73 can be a torsion spring with two force-generating ends. The torsion spring is coaxially sleeved on the rotating shaft of the gripper 72, with one force-generating end abutting against the mounting base 71 and the other force-generating end abutting against the side of the gripper 72 away from the mounting base 71, so as to apply a force to the gripper 72 to rotate toward the display panel 4, thereby clamping the display panel 4. In other embodiments of this disclosure, the second elastic member 73 can be a V-shaped spring sheet.

[0100] Thus, as the main body rotates to the first position, the gripper 72 also moves with the main body. Since the gripper 72 contacts the guide slope 14, the gripper 72 will slide along the guide slope 14, and the guide slope 14 will prevent the gripper 72 from moving synchronously with the main body. As a result, the gripper 72 gradually disengages from the display panel 4 until the main body is in the first position, at which point the gripper 72 is completely disengaged from the display panel 4. This reduces the possibility of the display panel 4 being bounced off during rotation and improves the reliability of the display device.

[0101] In one embodiment of this disclosure, see Figures 14-18 The gripper 72 includes a mounting portion 721, a guide portion 722, and a chuck 723. The mounting portion 721 is rotatably connected to the mounting base 71 via a pivot. The chuck 723 is integrally connected to the end of the mounting portion 721 away from the mounting base 71, passes through the main body, and is detachably connected to the display panel 4. The guide portion 722 is integrally connected to the mounting portion 721 and is used to contact the guide ramp 14 so that the guide ramp 14 separates the chuck 723 from the display panel 4 through the guide portion 722.

[0102] In one example, see Figures 14-16The guide portion 722 can be rod-shaped, and there are two guide portions 722, which are located on both sides of the mounting portion 721 and are coaxially arranged. The clamp 723 is hook-shaped, and the display panel 4 has a groove 42 on the side near the main body. The groove 42 has a V-shaped cross-section, and the clamp 723 can engage with the groove 42 to achieve a detachable connection with the display panel 4. When the main body is in the first position, the clamp 723 is separated from the groove 42. When the main body is in the second position, the clamp 723 engages with the groove 42.

[0103] In one embodiment of this disclosure, see Figure 14 , Figure 16 , Figure 17 A limiting block 15 is provided on the side of the guide slope 14 near the display panel 4. The limiting block 15 is used to prevent the guide part 722 from moving toward the display panel 4. In this way, when the main body is in the first position, the limiting block 15 can prevent the gripper 72 from continuing to move, thereby improving the stability of the structure.

[0104] In one embodiment of this disclosure, see Figure 14 , Figures 16-18 A first plane 16 is provided on the side of the guide slope 14 near the display panel 4, and the first plane 16 is parallel to the plane containing the first direction X and the second direction Y. A second plane 17 is provided on the side of the guide slope 14 away from the display panel 4, and the second plane 17 is parallel to the first plane 16. The guide part 722 can slide sequentially on the first plane 16, the guide slope 14, and the second plane 17. The limiting block 15 can be provided on the side of the first plane 16 away from the guide slope 14. This facilitates a smoother sliding of the guide part 722.

[0105] In one embodiment of this disclosure, see Figure 6 , Figure 7 , Figure 14 The clamping assembly 7 also includes a locking block 74, which is located on the side of the rotating frame 2 near the display panel 4. The side of the display panel 4 near the rotating frame 2 is provided with a slot 43. The slot 43 has an extension on one side wall near the gripper 72, which covers a part of the slot 43. The locking block 74 can be hook-shaped and can engage with the slot 43. During the rotation of the display panel 4, the locking block 74 engages with the slot 43, reducing the possibility of the display panel 4 falling accidentally and improving the reliability of the display device.

[0106] In one embodiment of this disclosure, the sidewall of the base 1 is provided with buffer strips. There can be multiple buffer strips, for example, two, three, four, etc. These multiple buffer strips can be distributed circumferentially along the inner sidewall of the base 1. Specifically, multiple buffer strips can be provided on two inner sidewalls of the base 1 distributed along a first direction X, extending along a second direction Y, contacting the sidewall of the rotating frame 2, and the material of the buffer strips is rubber. Thus, during the rotation of the main body to the first position, the buffer strips can provide cushioning force to the main body, allowing it to rotate more smoothly.

[0107] In one embodiment of this disclosure, see Figure 5 , Figure 7 , Figure 11 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.

[0108] 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.

[0109] 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. The buffer pin 13 may be made of rubber and may be provided on the side of the base 1 away from the display panel 4 by means of snap-fit, adhesive, or other methods. There may be multiple buffer pins 13, such as two, three, or four. Multiple buffer pins 13 may be distributed at intervals along the first direction X to buffer the pushing force applied to the display device by a person, which is beneficial to improving the service life of the display device.

[0110] In one embodiment of this disclosure, the rotating frame 2 may be provided with a clearance groove around its perimeter, so that a person can remove the display panel 4 by hand through the clearance groove, thereby reducing the possibility of the display panel 4 falling.

[0111] The working principle of this display device will be explained in detail below.

[0112] When it is necessary to disassemble the display panel 4, a person can push the display panel 4 inward by hand, so that the end of the mating part 51 away from the display panel 4 applies a force to the locking part 52, thereby driving the locking hook 521 away from the mating part 51 until the locking hook 521 disengages from the groove 511, so that the locking assembly 5 switches from the locked state to the unlocked state. When the locking assembly 5 switches to the unlocked state, the first elastic member 32 applies a force to the main body to rotate towards the first position, so that the main body rotates towards the first position with the rotation axis 31 as the axis. The main body drives the display panel 4 to rotate synchronously until the main body rotates to the first position, so that the display panel 4 passes through the open end and is located outside the receiving cavity. A person can then remove the display panel 4 from the main body to facilitate the disassembly of the display panel 4 and improve the disassembly efficiency of the display panel 4. As the main body rotates to the first position, the gripper 72 also moves with the main body. The guide 722 slides sequentially along the second plane 17, the guide slope 14, and the first plane 16. The guide slope 14 prevents the gripper 72 from moving synchronously with the main body, causing the chuck 723 to gradually separate from the groove 42. When the main body is in the first position, the chuck 723 is completely separated from the groove 42, thereby disengaging the chuck 723 from the display panel 4. The display panel 4 can then be easily removed by hand, reducing the possibility of the display panel 4 being thrown off during rotation and improving the reliability of the display device.

[0113] When the display panel 4 needs to be installed, the user manually fixes the display panel 4 to the main body using the magnetic attraction of the first magnet 24 and the second magnet 41, so that the locking block 74 engages with the slot 43 and the extension abuts against the locking block 74. Then, the user pushes the display panel 4, causing the main body to rotate to the second position. The display panel 4 also rotates synchronously with the main body. The mating part 51 extends into the inner cavity of the locking part 52 and applies force to the locking part 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. The user then releases the display panel 4, the main body is in the second position, and the locking assembly 5 is in the locked state to lock the main body and the display panel 4 into the receiving cavity, which facilitates the installation of the display panel 4 and improves the installation efficiency of the display panel 4. As the main body rotates to the second position, the gripper 72 also moves with the main body. The guide 722 slides sequentially along the first plane 16, the guide slope 14, and the second plane 17. The second elastic member 73 drives the gripper 72 to rotate closer to the display panel 4, so that the clamp 723 gradually extends into the groove 42 and gradually engages with the groove 42 until the main body is in the second position, at which point the clamp 723 and the groove 42 are fully engaged, thereby connecting the clamp 723 to the display panel 4, improving the installation stability of the display panel 4 and the reliability of the display device.

[0114] The display device has a simple structure, which facilitates the installation and removal of the display panel 4, thereby reducing costs and increasing automation.
