Detailed Implementation

[0052] 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.

[0053] 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.

[0054] This disclosure provides a display device. The display device can be a mobile phone, television, tablet computer, in-vehicle display device, in-flight display device, or other types of display device. For example, when the display device is an in-vehicle television, 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.

[0055] See FIGS. 1-5The display device includes a base 1, a connecting frame 2, a display panel 3, an elastic component 4, a locking component 5, and an unlocking component 6. The base 1 includes a receiving cavity with an open end 11. The connecting frame 2 includes a main body 21 and a frame 22 connected along a first direction X. The main body 21 is disposed within the receiving cavity and is movable along the first direction X between at least a first position and a second position. When the main body is in the first position, the frame 22 is located within the receiving cavity; when the main body is in the second position, the frame 22 is located outside the receiving cavity. The display panel 3 is detachably disposed on the frame 22. The elastic component 4 is disposed on the base 1 and abuts against the main body 21, applying a force toward the frame 22 to the main body 21. The locking component 5 is disposed on the base 1 and connected to the connecting frame 2, and can switch between a locked state and an unlocked state. In the locked state, the locking component 5 prevents the main body 21 from moving to the second position; in the unlocked state, the main body 21 can move between the first and second positions. The unlocking component 6 is located on the base 1 and connected to the adapter frame 2; the unlocking component 6 enables the locking component 5 to switch between the locked state and the unlocked state.

[0056] Thus, when the display panel 3 needs to be disassembled, the unlocking component 6 switches the locking component 5 from the locked state to the unlocked state. During the switching process, the unlocking component 6 drives the adapter frame 2 to move along the first direction X toward the first position (the unlocking component 6 drives the adapter frame 2 to move away from the second position along the first direction X). The display panel 3 moves to the first position along the first direction X with the frame 22, so that the main body 21 is in the unlocked state. Then, under the action of the elastic component 4, the main body 21 moves from the first position to the second position along the first direction X. The frame 22 drives the display panel 3 to move synchronously with the main body 21. The unlocking component 6 also moves from the first position to the second position along the first direction X until the frame 22 and the display panel 3 move to the second position, so that the display panel 3 passes through the open end 11 and is located outside the receiving cavity. The display panel 3 can be removed from the frame 22 by hand, which facilitates the automatic disassembly of the display panel 3 and improves the disassembly efficiency of the display panel 3.

[0057] When the display panel 3 needs to be installed, the display panel 3 is placed on the frame 22 by hand. At this time, the display panel 3 and the frame 22 are in the second position. The unlocking component 6 drives the main body 21 to move from the second position to the first position along the first direction X. The frame 22 and the main body 21 also move synchronously with the main body 21, so that the display panel 3 enters the receiving cavity from the opening end until the unlocking component 6 stops moving. At this time, the locking component 5 locks the adapter frame 2 in the locked state and the adapter frame 2 is in the position between the first position and the second position. The elastic component 4 applies a force to the adapter frame 2 towards the second position to facilitate the automatic installation of the display panel 3 and improve the installation efficiency of the display panel 3. When the display panel 3 is installed, the display panel 3 and the adapter frame 2 can be moved by hand until the adapter frame 2 is in the locked state.

[0058] In one embodiment of this disclosure, the display panel 3 may be a light-emitting diode (LED) display panel, an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, or other types of display panels.

[0059] In one embodiment of this disclosure, see FIG. 5 , FIG. 6 , FIG. 7 The main body 21 is provided with a slider 211. The locking assembly 5 includes a rotating member 51, which is rotatably connected to the base 1. The rotating member 51 is provided with a guide groove 511, which has an open end and a closed end distributed along a first direction X, and the open end is located on the side of the closed end closer to the display panel 3. The bottom of the guide groove 511 has a protruding blocking part 512. When the locking assembly 5 is in the locked state, the slider 211 is limited between the blocking part 512 and the closed end; when the locking assembly 5 is in the unlocked state, the slider 211 is located between the blocking part 512 and the side wall of the guide groove 511. Thus, during the process of switching the main body 21 from the locked state to the unlocked state, the unlocking component 6 drives the slider 211 to slide towards the closed end of the guide groove 511, causing the slider 211 to separate from the blocking part 512. At the same time, the slider 211 causes the rotating member 51 to rotate until the rotating member 51 and the slider 211 are in the unlocked state, at which point the slider 211 is located between the blocking part 512 and the side wall of the guide groove 511. Through the blocking part 512, in the locked state, the slider 211 can be prevented from moving towards the open end along the first direction X, so as to facilitate the locking of the adapter frame 2.

[0060] In one embodiment of this disclosure, see FIG. 6 , FIG. 7The blocking portion 512 has a recessed portion on its surface facing the closed end, which is recessed towards the open end. The recessed portion has intersecting first side surface 5121 and second side surface 5122. The included angle between the first side surface 5121 and the second side surface 5122 is less than 180°. For example, the included angle between the first side surface 5121 and the second side surface 5122 can be 30°, 60°, 90°, 120°, 179°, etc., to facilitate locking the slider 211 in the recessed portion. The surface facing the open end of the closed end has a protrusion that protrudes towards the open end. The protrusion has intersecting third side surface 5111 and fourth side surface 5112, and the included angle between the third side surface 5111 and the fourth side surface 5112 is less than 180°. For example, the included angle between the third side surface 5111 and the fourth side surface 5112 can be 30°, 60°, 90°, 120°, 179°, etc., to facilitate guiding the slider 211 to slide in the guide groove 511 during unlocking.

[0061] In one embodiment of this disclosure, in the locked state, the slider 211 abuts against the surface of the recess, and there is a gap between the slider 211 and the protrusion. This facilitates unlocking of the adapter frame 2 and prevents the slider 211 from becoming stuck in the recess.

[0062] In one embodiment of this disclosure, the surface of the closed end facing the open end has a groove recessed towards the open end. The groove is located near the protrusion and communicates with the guide groove 511. During the unlocking process of the slider 211, the slider 211 can slide into the groove to reduce the possibility of the slider 211 getting stuck.

[0063] In one embodiment of this disclosure, see FIGS. 5-7 When the slider 211 unlocks in the guide groove 511, it has a slidable first channel and a second channel. The first channel is composed of a first side surface 5121 and a third side surface 5111, and the second channel is composed of a second side surface 5122 and a fourth side surface 5112. The closed end has two grooves, with one channel corresponding to one groove. Thus, by providing the first and second channels, on the one hand, during the unlocking process of the slider 211, if the slider 211 cannot slide into the first channel, it can slide into the second channel to facilitate unlocking and prevent the slider 211 from getting stuck in the guide groove 511. On the other hand, during the locking process of the slider 211, the slider 211 can slide into the recess through either the first or second channel to facilitate locking.

[0064] In one embodiment of this disclosure, the slider 211 can be a prism, frustum, cylinder, frustum or other irregular geometric shape, which is not limited here.

[0065] In one embodiment of this disclosure, see FIG. 6 , FIG. 7The surface of the blocking portion 512 facing the opening end forms a protruding structure protruding towards the opening end through the intersecting fifth side surface 5123 and sixth side surface 5124. The included angle between the fifth side surface 5123 and the sixth side surface 5124 is less than 180°. For example, the included angle between the fifth side surface 5123 and the sixth side surface 5124 can be 30°, 60°, 90°, 120°, 179°, etc. The fifth side surface 5123 and the side wall of the guide groove 511 form a third channel, and the sixth side surface 5124 and the side wall of the guide groove 511 form a fourth channel; the third channel communicates with the first channel, and the second channel communicates with the fourth channel. The portion of the guide groove 511, the third channel, and the fourth channel located between the blocking portion 512 and the opening end are interconnected to form a fifth channel, that is, the third channel and the fourth channel merge into the fifth channel at the blocking portion 512 and the opening end. Thus, the slider 211 can slide from the recessed part through the first channel and the third channel in sequence and then slide into the fifth channel. Alternatively, it can slide from the recessed part through the second channel and the fourth channel in sequence and then slide into the fifth channel, so that the display panel 3 leaves the receiving cavity.

[0066] In one embodiment of this disclosure, see FIG. 5 and FIG. 7 The rotating member 51 is rotatably connected to the base 1 at its open end, and at least one limiting strip 513 is provided at its closed end. For example, the number of limiting strips 513 can be one, two, three, etc. The base 1 has a limiting block 12, which has a limiting groove 121 for accommodating at least one limiting strip 513. When the rotating member 51 rotates, at least one limiting strip 513 moves in the limiting groove 121. Thus, when the rotating member 51 rotates, the limiting strip 513 can rotate in the limiting groove 121 to limit the angle at which the rotating member 51 can rotate.

[0067] In one embodiment of this disclosure, see FIG. 5 and FIG. 7 There are three limiting strips 513, one of which is located in the limiting groove 121, and the other two are located outside the limiting groove 121 and on the side of the limiting block 12 away from the base 1. In this way, when the rotating member 51 rotates, the cooperation between the three limiting strips 513 and the limiting block 12 can prevent the rotating member 51 from moving along the second direction Y, so as to achieve the stability and smoothness of the rotating member 51 during the rotation process.

[0068] In one embodiment of this disclosure, see FIG. 5The base 1 is fixedly connected to a support plate 13, and a reinforcing rib is fixedly connected between the support plate 13 and the base 1. The rotating component 51 has a rotating shaft 514 and two arc-shaped portions 515 at its open end. The rotating shaft 514 is rotatably connected to the support plate 13, and the two arc-shaped portions 515 are evenly distributed along the circumference of the rotating shaft 514. The arc-shaped portions 515 are disposed through the support plate 13, and the support plate 13 is provided with arc-shaped grooves for the arc-shaped portions 515 to pass through and move. In this way, when the rotating component 51 rotates, the arc-shaped portions 515 will rotate with the rotating shaft 514 in the arc-shaped grooves, so as to achieve smooth rotation of the rotating component 51 and improve the stability of the locking assembly 5.

[0069] In one embodiment of this disclosure, see FIG. 8 The elastic component 4 includes at least one elastic element, which is a compression spring 41. One end of the compression spring 41 is connected to the base 1, and the other end abuts against the side of the main body 21 away from the frame 22. The axis of the compression spring 41 extends along the first direction X and applies a force toward the frame 22 to the main body 21. Thus, when the adapter frame 2 is in the unlocked state, the compression spring 41 can push the adapter frame 2 from the first position to the second position along the first direction X, thereby realizing the automatic disassembly of the display panel 3.

[0070] In one embodiment of this disclosure, there are two compression springs 41. The two compression springs 41 are distributed along a third direction Z in the receiving cavity of the base 1. One end of each compression spring 41 is fixedly connected to the side wall of the receiving cavity away from the open end 11, and the other end abuts against the side of the main body 21 away from the frame 22. The side of the main body 21 away from the frame 22 has a spring cavity, and the compression spring 41 abuts against the spring cavity. A guide rod extending along a first direction X can be provided in the spring cavity, and the compression spring 41 can be sleeved on the guide rod. Thus, by placing one end of the compression spring 41 in the spring cavity and sleeved on the guide rod, the compression spring 41 is guided during extension and retraction, thereby improving structural stability.

[0071] In one embodiment of this disclosure, see FIG. 3 , FIG. 4 The unlocking assembly 6 includes an electromagnetic push rod 61 arranged along a first direction X. The electromagnetic push rod 61 has a fixed part and a movable part. The fixed part is connected to the side of the base 1 away from the open end 11 by two screws. The movable part is fixedly connected to the main body 21 by a snap-fit ​​connection. The electromagnetic push rod 61 is located between two compression springs 41. The electromagnetic push rod 61 is used to move the slider 211 along the first direction X away from the blocking part 512 to a position abutting against the protrusion. Thus, the electromagnetic push rod 61 can drive the adapter frame 2 to move along the first direction X, thereby realizing the locking and unlocking operation of the adapter frame 2.

[0072] In one embodiment of this disclosure, see FIG. 4 and FIG. 8 The main body 21 is rotatably connected to a damping gear 212, the axis of which extends along the second direction Y. The base 1 is provided with a rack portion 14 for meshing with the damping gear 212, the rack portion 14 extending along the first direction X. During the movement of the main body 21 along the first direction X, the damping gear 212 meshes with the rack portion 14 to provide damping to the main body 21, facilitating smooth movement of the main body 21 along the first direction X.

[0073] In one embodiment of this disclosure, the base 1 has a damping groove for accommodating the damping gear 212 on the side away from the rotating member 51. The damping groove extends along a first direction X, and the rack portion 14 is disposed in the damping groove.

[0074] In one embodiment of this disclosure, see FIG. 4 and FIG. 8 The main body 21 is also provided with at least one guide block 213. The base 1 has a guide groove 15 along the first direction X for sliding the guide block 213. The guide block 213 extends into the guide groove 15 and slides. In this way, the guide block 213 can slide along the guide groove 15 to facilitate the movement of the main body 21 along the first direction X.

[0075] In one embodiment of this disclosure, see FIG. 4 and FIG. 8 The main body 21 is also provided with three guide blocks 213 distributed along the third direction Z; there are three guide grooves 15, which extend along the third direction Z and are located on the side of the base 1 away from the rotating member 51. One guide block 213 corresponds to one guide groove 15, and the guide block 213 extends out of the guide groove 15. In this way, the three guide blocks 213 slide in their respective guide grooves 15 to guide the main body 21 to move along the first direction X, thereby facilitating the entry and exit of the display panel 3 into or out of the receiving cavity.

[0076] In one embodiment of this disclosure, see FIG. 3 , FIG. 4 , FIG. 8 The display device also includes a clamping assembly 7. The clamping assembly 7 includes grippers 71, which are disposed on the side wall of the main body 21 extending in a third direction Z and are used to clamp the display panel 3. The base 1 has a through groove 16 for the grippers 71 to pass through, and the through groove 16 extends in a first direction X. Thus, during the movement of the display panel 3 along the first direction X by the main body 21 and the frame 22, the two grippers 71 clamp the display panel 3 to prevent it from falling out of the frame 22 and being damaged, thereby improving the reliability of the display device.

[0077] In one embodiment of this disclosure, seeFIG. 4 There are two clamping components 7, each of which includes a gripper 71. The two grippers 71 are respectively located on both sides of the main body 21 extending in the third direction Z, so as to clamp the display panel 3.

[0078] In one embodiment of this disclosure, see FIGS. 8-11 The gripper 71 includes a mounting portion 711, a torsion spring 712, and a clamp 713. The gripper 71 is located outside the receiving cavity. The mounting portion 711 is mounted to the side wall of the main body 21 via the torsion spring 712, which provides a force to rotate the clamp 713 towards the main body 21. The clamp 713 is connected to the mounting portion 711 and can pass through the through slot 16 to clamp the display panel 3. Thus, the torsion spring 712 applies a force to bring the two clamps 713 closer together, facilitating the clamping of the display panel 3.

[0079] In one embodiment of this disclosure, the clamp 713 is hook-shaped to facilitate clamping the display panel 3. Of course, the clamp 713 can also be block-shaped, column-shaped, or irregularly shaped, depending on actual needs, and is not limited here.

[0080] In one embodiment of this disclosure, the display panel 3 may be provided with locking grooves on both sides along the third direction Z for locking the clamp 713, so that the clamping claws can clamp the display panel 3 more stably.

[0081] In one embodiment of this disclosure, see FIG. 9 , FIG. 10 , FIG. 11 The gripper 71 also includes a stop bar 714, which extends along the second direction Y and is fixedly connected to the end of the mounting part 711 away from the chuck 713. Along the second direction Y, the size of the through groove 16 is smaller than the size of the stop bar 714; along the first direction X, when the stop bar 714 abuts against the base 1, the chuck 713 disengages from the display panel 3. Thus, as the main body 21 moves towards the second position along the first direction X, the gripper 71 and the stop bar 714 also move synchronously. However, because the size of the through groove 16 is smaller than the size of the stop bar 714, the stop bar 714 cannot pass through the through groove 16 and is blocked by the side wall of the base 1. At this time, the main body 21 continues to move towards the second position along the first direction X under the action of the compression spring 41, causing the torsion spring 712 to experience resistance. This causes the two mounting parts 711 to drive the chuck 713 to rotate, causing the two chucks 713 to move away from each other until the chuck 713 disengages from the display panel 3, thereby realizing the automatic release of the clamping assembly 7 from the display panel 3.

[0082] In one embodiment of this disclosure, see FIG. 9 , FIG. 10 , FIG. 12The frame portion 22 is provided with a clamping groove 221 for the clamp 713 to pass through. The clamp 713 can clamp the display panel 3 through the clamping groove 221, and the clamp 713 can move within the clamping groove 221. In this way, the clamp 713 can clamp the display panel 3, improving the reliability of the display device.

[0083] In one embodiment of this disclosure, see FIG. 8 The frame portion 22 is provided with clearance grooves 222 on both sides along the second direction Y, so that a part of the display panel 3 is exposed to the air through the clearance grooves 222, and a person can touch the display panel 3 through the clearance grooves 222 and easily disassemble the display panel 3.

[0084] In one embodiment of this disclosure, see FIG. 3 and FIG. 8 The display device also includes a magnet 8, which is disposed on the main body 21 and passes through the frame 22 to magnetically attract the display panel 3. The display panel 3 has an iron block or magnet for magnetic attraction by the magnet 8. Thus, when the display panel 3 and the frame 22 are pushed out of the receiving cavity from the open end 11 by the compression spring 41, the clamp 713 disengages from the display panel 3, and the magnet 8 holds the display panel 3 in place, effectively preventing the display panel 3 from being bounced away by the spring force, thereby further improving the reliability of the display device.

[0085] In one embodiment of this disclosure, the display panel 3 may have a screen soft switch for controlling the extension and retraction of the electromagnetic push rod 61, so that the electromagnetic push rod 61 can be extended or retracted by pressing the screen soft switch.

[0086] The working principle of this display device will be explained in detail below.

[0087] When it is necessary to disassemble the display panel 3, the electromagnetic push rod 61 is in the locked state. First, the electromagnetic push rod 61 shortens, causing the main body 21 to move the frame 22, display panel 3, slider 211, and gripper 71 along the first direction X toward the first position. The slider 211 slides from the recess along the first channel of the guide groove 511, or the slider 211 slides from the recess along the second channel of the guide groove 511. Since the slider 211 is in contact with the side wall of the guide groove 511, the rotating part 51 will rotate until the slider 211 is in the unlocked state. Then, the compression spring 41 pushes the main body 21 to move the frame 22, display panel 3, slider 211, and gripper 71 toward the first position. The main body 21 moves towards the second position along the first direction X. The frame 22, display panel 3, and gripper 71 also move synchronously with the main body 21. When the stop bar 714 abuts against the base 1, the two mounting parts 711 drive the gripper 713 to rotate, causing the two grippers 713 to move away from each other and disengage from the display panel 3 until the display panel 3 is in the second position. At this time, the display panel 3 is outside the receiving cavity, the main body 21 stops moving, and the display panel 3 can be removed from the frame 22 by hand, which facilitates the disassembly of the display panel 3 and improves the disassembly efficiency of the display panel 3. When the display panel 3 moves from the first position to the second position, the electromagnetic push rod 61 can be de-energized, allowing the electromagnetic push rod 61 to extend freely under the force of the compression spring 41; or, the electromagnetic push rod 61 can extend actively, pushing the main body 21 from the first position to the second position.

[0088] When the display panel 3 needs to be installed, the display panel 3 is manually placed on the frame 22. At this time, the display panel 3 and the frame 22 are in the second position. The electromagnetic push rod 61 retracts, driving the main body 21 to move from the second position to the first position along the first direction X. The frame 22 and the main body 21 also move synchronously with the main body 21, so that the display panel 3 enters the receiving cavity from the opening end until the main body 21 is in the locked state. At this time, the rotating member 51 locks the adapter frame 2 and places the adapter frame 2 in a position between the first and second positions. The compression spring 41 applies a force to the adapter frame 2 towards the second position to facilitate the automatic installation of the display panel 3 and improve the installation efficiency of the display panel 3. During this process, the two clamps 713 clamp the display panel 3 due to the action of the torsion spring 712. When slider 211 slides along guide groove 511, slider 211 will contact fifth side surface 5123, thereby sliding into recessed portion through third channel and first channel in sequence. Alternatively, slider 211 will contact sixth side surface 5124, thereby sliding into recessed portion through fourth channel and second channel in sequence, so that slider 211 is in a locked state.

[0089] The display device has a simple structure, which facilitates the installation and removal of the display panel, thereby reducing costs and increasing automation.
