[0046] In this paper, the first direction X, the second direction Y, and the third direction Z intersect each other in pairs, and the angle between any two directions can be 90°, so that the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Of course, the aforementioned angle can also be other than 90°.

[0047] 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 view images 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.

[0048] See Figures 1-7 The display device disclosed herein may include a base 1, a display panel 2, a locking assembly 3, a transmission assembly 4, and a drive assembly 5, wherein:

[0049] The base 1 includes a receiving cavity having an open end and a closed end distributed along a first direction X;

[0050] The display panel 2 covers the closed end, and the surface of the display panel 2 near the base 1 is provided with a hook part;

[0051] The locking assembly 3 includes a locking hook 31 and a connecting rod 32. The locking hook 31 has a hook portion 311 and a positioning portion 312 distributed along a first direction X. The positioning portion 312 is located in the receiving cavity, and the hook portion 311 extends toward the display panel 2. The locking hook 31 is rotatably disposed in the base 1. The rotation axis of the locking hook 31 is located between the positioning portion 312 and the hook portion 311, and extends along a second direction Y, which intersects with the first direction X. The locking hook 31 can rotate around its rotation axis between a first position and a second position. When it is in the first position, the hook portion 311 engages with the hooking portion, preventing the display panel 2 from moving away from the base 1 along the first direction X. When the locking hook 31 is in the second position, the hook portion 311 disengages from the hooking portion. The connecting rod 32 is disposed in the receiving cavity and connected to the locking hook 31.

[0052] The transmission assembly 4 is disposed within the receiving cavity and is connected to the connecting rod 32. The drive assembly 5 is connected to the transmission assembly 4 and is used to drive the locking hook 31 to rotate from the first position to the second position via the transmission assembly 4 and the connecting rod 32.

[0053] The display device of this embodiment can lock and unlock the base 1 and the display panel 2 by engaging or disengaging the locking hook 31 with the hooking part. Specifically, when the locking hook 31 is in the first position, it engages with the hooking part, preventing the display panel 2 from separating from the base 1, thus locking the display panel 2. When the locking hook 31 is in the second position, it disengages from the hooking part, allowing the display panel 2 to be separated from the base 1, thus disassembling the display panel 2. Simultaneously, the drive assembly 5 can rotate the locking hook 31 via the transmission assembly 4 and the connecting rod 32, thereby achieving the aforementioned unlocking. The structure is simple, which helps reduce costs and facilitates installation and disassembly.

[0054] The following is a detailed description of each part of the display device:

[0055] The base 1 is a hollow structure with a receiving cavity. The receiving cavity has an open end and a closed end distributed along a first direction X. The open end allows the receiving cavity to communicate with the outside. The receiving cavity can be equipped with a locking component 3, a transmission component 4, etc. In some embodiments of this disclosure, the base 1 may include a rear cover and a side plate 521 surrounding the rear cover. The rear cover and the side plate 521 form the receiving cavity, and the rear cover may be integrally formed with the side plate 521. The side of the side plate 521 closer to the rear cover is the closed end, and the side of the side plate 521 away from the rear cover is the open end.

[0056] The specific type of display panel 2 is not specifically limited here; it can be a self-emissive OLED display panel, an LED display panel, or a liquid crystal display panel, etc. Display panel 2 may include a body for displaying images and a back cover 21 located on the side of the body near the base 1.

[0057] See Figures 3-7 The locking assembly 3 may include a locking hook 31 and a connecting rod 32, wherein:

[0058] The locking hook 31 has a hook portion 311 and a positioning portion 312 distributed along a first direction X. The positioning portion 312 may be located within the receiving cavity, while the hook portion 311 extends toward the display panel 2, thus protruding from the open end. The hook portion 311 may include a main body 3111 extending along the first direction X and a claw portion 3112 extending toward one side of the main body 3111. The positioning portion 312 and the hook portion 311 may be an integral structure, or they may be independent structures connected by means of snap-fit ​​or the like.

[0059] The locking hook 31 is rotatably disposed within the base 1. For example, the locking hook 31 can be rotatably connected to the inner wall of the base 1 via a rotating shaft 33, and the rotation axis of the locking hook 31 is located between the positioning part 312 and the hook part 311, that is, the rotating shaft 33 passes between the hook part 311 and the positioning part 312; at the same time, the rotating shaft 33 can extend along the second direction Y, that is, the rotation axis of the locking hook 31 can extend along the second direction Y. The locking hook 31 can rotate around its rotation axis between a first position and a second position. When the positioning part 312 is pushed, the hook part 311 will rotate. When the locking hook 31 is in the first position, the hook part 311 engages with the hooking part, that is, the claw part 3112 is blocked by the hooking part, preventing the display panel 2 from moving away from the base 1 along the first direction X, so that the display panel 2 cannot be detached; when the locking hook 31 is in the second position, the hook part 311 disengages from the hooking part, at this time the claw part 3112 of the hook part 311 no longer contacts the hooking part, and the display panel 2 can be disassembled.

[0060] See Figures 3-7 To cooperate with the locking assembly 3, a hook portion can be provided on the rear shell 21 of the display panel 2. This hook portion can include an opening 211 in the rear shell 21, through which the hook portion 311 passes. When the hook 31 is in the first position, the hook portion 311 is blocked by the rear shell 21, i.e., the claw portion 3112 of the hook portion 311 is blocked. When the hook 31 is in the second position, the rear shell 21 disengages from the hook portion 311. Furthermore, a protruding hanging ear 212 can be provided on the surface of the rear shell 21 away from the base 1. The hanging ear 212 can be located at the edge of the opening 211. When the hook 31 is in the first position, the hook portion 311 can hook onto the hanging ear 212, i.e., the claw portion 3112 of the hook portion 311 can be hooked onto the hanging ear 212. The lug 212 can be integrally formed with the back shell 21, and it can be regarded as a portion of the edge of the opening 211 curled away from the base 1.

[0061] See Figures 3-7 The connecting rod 32 can be disposed within the receiving cavity and connected to the locking hook 31, used to drive the locking hook 31 to rotate, thereby unlocking. The transmission assembly 4 is disposed within the receiving cavity and connected to the connecting rod 32. The drive assembly 5 is connected to the transmission assembly 4. Under the drive of the drive assembly 5, the connecting rod 32 can be moved through the transmission assembly 4, thereby driving the locking hook 31 to rotate from the first position to the second position. The following is an exemplary description:

[0062] In some embodiments of this disclosure, the transmission assembly 4 may include a first gear 41 rotatably connected within a receiving cavity, the axial direction of the first gear 41 being a first direction X. The connecting rod 32 has a first rack portion 321 that meshes with the first gear 41, the first rack portion 321 extending along a third direction Z, and when the first gear 41 rotates, it can drive the first rack portion 321 to move along the third direction Z. The connecting rod 32 is also connected to a locking hook 31 and can drive the locking hook 31 to rotate.

[0063] Further, see Figures 3-7 The link 32 may also include a connecting portion 322, which extends along a third direction Z and passes through the positioning portion 312. The connecting portion 322 is connected to the first rack portion 321, and the two can move synchronously along the third direction Z. For example, the link 32 may also include a transition portion 323, which extends along a second direction Y, with one end connected to the first rack portion 321 and the other end connected to one end of the connecting portion 322; at least two of the first rack portion 321, the transition portion 323, and the connecting portion 322 may be an integral structure, or they may be independent structures that are fixedly connected.

[0064] The connecting part 322 has a toggle member 324, which can be a columnar structure passing through the connecting part 322 along the second direction Y, or a structure protruding along the second direction Y on the connecting part 322. The toggle member 324 can be located on the side of the positioning part 312 away from the first gear 41. When the connecting rod 32 moves closer to the first gear 41 along the third direction Z, the toggle member 324 can push the positioning part 312 to rotate, thereby rotating the lock hook 31 and unlocking the device.

[0065] Furthermore, the locking hook 31 can be reset in various ways. For example, a torsion spring can be installed at the pivot 33 to apply a force to the locking hook 31 to rotate it to the first position. This force needs to be overcome when unlocking. Alternatively, a spring connected to the locking hook 31 can be installed in the receiving cavity to apply a force to the locking hook 31 to rotate it to the first position. Alternatively, two actuating members 324 can be installed on the connecting part 322, and the positioning part 312 can be limited between the two actuating members 324. The reciprocating rotation of the first gear 41 drives the connecting rod 32 to reciprocate in the third direction Z, thereby driving the locking hook 31 to reciprocate between the first position and the second position.

[0066] See Figure 4 , Figure 6 and Figure 7 The drive assembly 5 is connected to the first gear 41 and can drive the first gear 41 to rotate. When the first gear 41 rotates, it can drive the connecting rod 32 to move along the third direction Z through the first rack portion 321, so that the locking hook 31 rotates from the first position to the second position. In some embodiments of this disclosure, unlocking can be achieved by electronic control. Specifically, the drive assembly 5 may include a motor assembly 51, which is connected to the first gear 41 and can drive the first gear 41 to rotate. For example, the motor assembly 51 includes a motor, which may have an output shaft 511. The output shaft 511 may be connected to the first gear 41 by a key or other means, and the rotation of the output shaft 511 drives the first gear 41 to rotate.

[0067] In some embodiments of this disclosure, unlocking can be achieved manually. Specifically, the transmission assembly 4 further includes a second gear 42, which is coaxially connected to the first gear 41 and can rotate synchronously. For example, the second gear 42 has an axially extending protrusion 422, which can axially penetrate the first gear 41 and be fixedly connected to the first gear 41 by a key connection (e.g., spline), threaded connection, or other means, so that the two can rotate synchronously. The display device also includes a pressing member 52, which can be disposed on the base 1 and slidably engaged with the base 1. The pressing member 52 can reciprocate along the second direction Y. The pressing member 52 also has a second rack portion located within a receiving cavity, which extends along the second direction Y and meshes with the second gear 42. At least one end of the pressing member 52 in the second direction Y can protrude from the base 1, i.e., the base 1 can be provided with a clearance hole for the pressing member 52 to pass through. The user can manually press the pressing member 52 to move it along the second direction Y. At this time, the second rack can drive the second gear 42 to rotate, and the second gear 42 can drive the first gear 41 to rotate. The first gear 41 can rotate the locking hook 31 through the connecting rod 32 to unlock. Thus, the display panel 2 can be unlocked by manually pressing the pressing member 52.

[0068] See Figure 5 , Figure 6 and Figure 8 In some embodiments, the pressing member 52 may also have a hollow structure, which may include two side plates 521 distributed along a third direction Z and a connecting plate 522 connecting the two side plates 521. There may be multiple connecting plates 522, meaning the two side plates 521 can be connected by multiple connecting plates 522. However, the side of the pressing member 52 facing the first gear 41 should be an open structure to ensure that the second gear 42 can be located between the side plates 521. The side plates 521 and the connecting plate 522 may be an integral structure or fixedly connected independent structures. See also... Figure 9 The gear portion 421 of the second gear 42 may be located between the two side plates 521, that is, the distance between the two side plates 521 is greater than the diameter of the second gear 42. At least one side plate 521 is provided with a second rack portion, which meshes with the second gear 42 inside the pressing member 52.

[0069] See Figure 8The drive assembly 5 in the display device of this disclosure may simultaneously include the aforementioned motor assembly 51, pressing member 52, and second gear 42. That is, unlocking can be achieved through both electronic and manual methods. Furthermore, while the motor assembly 51 drives the first gear 41 to rotate, the second gear 42 rotates synchronously with the first gear 41, causing the pressing member 52 to move along the second direction Y even when not pressed. Of course, in some embodiments of this disclosure, the drive device may only have the motor assembly 51, without the second gear 42 and pressing member 52, and can only be unlocked electronically; or it may only have the second gear 42 and pressing member 52, without the motor assembly 51, and can only be unlocked manually.

[0070] The number of locking components 3 mentioned above can be one or two, and the connecting rods 32 of the two locking components 3 can extend outwards from the first gear 41 in opposite directions. That is, both first rack portions 321 mesh with the first gear 41, and the connecting portion 322 extends away from the first gear 41. At the same time, two hook portions can be provided on the surface of the display panel 2 near the base 1, that is, on the back shell 21, which can cooperate with the two locking hooks 31 one-to-one. When the first gear 41 rotates, the two connecting rods 32 move in opposite directions in the third direction Z, driving the two locking hooks 31 to rotate respectively, so as to unlock. The specific principle can be referred to above, and will not be repeated here.

[0071] Furthermore, in some embodiments of this disclosure, the locking hooks 31 of the two locking components 3 can be distributed along a third direction Z on both sides of the first gear 41 and are symmetrically arranged about the axis of the first gear 41; while the first rack portions 321 of the two locking components 3 can be distributed along a second direction Y on both sides of the first gear 41 and are symmetrically arranged about the axis of the first gear 41; that is, the two first rack portions 321 and the two locking hooks 31 are distributed along the circumference of the first gear 41, so that the force on the display panel 2 can be more even, avoiding problems such as jamming. In addition, the transition portion 323 of the connecting rod 32 can extend along the second direction Y, so that the first rack portion 321 and the connecting portion 322 are parallel to each other extending along a third direction Z.

[0072] This disclosure also provides a vehicle. The vehicle can be an automobile, train, bullet train, high-speed train, or other type of vehicle. The vehicle may include a vehicle body, a vehicle frame, and a display device according to any of the above embodiments. The display device is disposed within the vehicle frame, and the specific structure and beneficial effects of the display device can be referred to the embodiments of the display device described above, and will not be detailed here.

[0073] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
