[0002] In-vehicle displays are becoming increasingly common in vehicle interiors. As people's demands for displays increase, the field of in-vehicle displays also faces higher requirements. In order to display more entertainment content, such as videos and games, in-vehicle displays have increased in size from small and medium-sized to large sizes, and the requirements for the screen-to-body ratio (the ratio of the display area to the total area of ​​the in-vehicle display device) are also getting higher and higher.

[0003] Traditional vehicle-mounted displays include a transparent cover, a display assembly, a backlight component 3, and a housing. To secure the backlight component 3 and prevent it from vibrating and dislodging, the vehicle-mounted display also includes a ring-shaped retaining component 9, such as... Figure 4 As shown, the cross-section of the limiting member 9 is Z-shaped. Its first end 91 is sandwiched between the transparent cover plate 1 and the housing 4. The second end 92 is connected to the first end 91 through the bent connecting part 93. The second end 92 extends above the backlight member 3. The setting of the connecting part 93 restricts the position of the inner wall surface of the housing 4. The housing 4 cannot be further recessed, which also makes it difficult to further reduce the width of the bezel of the vehicle display device along the extension direction of the first end, that is, it is difficult to further increase the screen ratio, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a display device and vehicle to solve the problems of small screen ratio and poor user experience of the display device.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The display assembly and the backlight component are both disposed within the receiving space. The limiting component is located within the mounting groove and is connected to the transparent cover plate via a first connector. A portion of the limiting component extends to the backlight component and forms a limiting space with the housing.

[0007] Optionally, the limiting member is a ring-shaped structure, and the mounting groove is set as an annular shape.

[0008] Optionally, the first connector is bonded to the transparent cover plate, and / or the first connector is bonded to the limiting member.

[0009] Optionally, the first connector is disposed on the side of the limiting member near the inner wall of the housing.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] The embodiments of this utility model propose a display device, including but not limited to in-vehicle screens such as central control screens, rear seat screens, and passenger-side screens, and can also be used as a standalone display device or applied in wearable display products and portable mobile devices. (Reference) Figure 1 As shown, the display device includes a transparent cover plate 1, a display assembly 2, a backlight component 3, a limiting component 8, a first connecting component 6, and a housing 4. The housing 4 and the transparent cover plate 1 are fixedly connected by means including but not limited to adhesive bonding. The display assembly 2, the backlight component 3, and the limiting component 8 are all located within the protective space formed by the housing 4 and the transparent cover plate 1. Optionally, the transparent cover plate 1 is made of glass, such as CG glass, to give it high transparency, thereby avoiding affecting the display effect of the content displayed on the display assembly 2. It can also withstand physical damage such as drops and scratches during daily use, extending the service life of the display assembly 2. The housing 4 can be made of metal to give the display device a longer service life. The backlight component 3 is disposed between the display assembly 2 and the housing 4. A mounting groove 41 is formed on the inner wall of the housing 4. The limiting component 8 is located in the mounting groove 41 and partially extends to the backlight component 3, forming a limiting space with the housing 4 to limit the backlight component 3. The first connecting component 6 is fixedly connected to the transparent cover plate 1 and the limiting component 8.

[0029] In existing display devices, the limiting member 9, used to restrict the vibration and dislodgement of the backlight component 3, is restricted by the display assembly 2 and cannot move further inward. This causes the connecting part 93 of the backlight component 3 to restrict the inward retraction of the housing 4, making it difficult to further increase the screen-to-body ratio. However, in the display device of this utility model embodiment, the limiting member 8 is fixedly connected to the transparent cover plate 1 by the first connecting member 6, thereby fixing it relative to the housing 4 under the action of the transparent cover plate 1. Compared with the original method of fixing by clamping the housing 4 with the transparent cover plate 1, this is equivalent to eliminating the bending connecting part 93 and the first end 91 of the original limiting member 9, thereby eliminating the restriction of the limiting member 8 on the inner wall position of the housing 4. Under the premise that the overall thickness of the housing 4 remains unchanged (based on the structural strength considerations of the housing 4), the housing 4 can be retracted inward by a distance equal to the width of the connecting part 93, allowing the housing 4 to be partially moved below the limiting member 8, while the effective display area size of the display device remains unchanged, thus increasing the screen-to-body ratio of the display device. The setting of the first connecting member 6 maintains the stability of the limiting member 8. Understandably, the mounting slot 41 not only allows the limiting member 8 to be closer to the backlight member 3, effectively preventing the backlight member 3 from vibrating and jumping off, but also avoids interference between the limiting member 8 and the display assembly 2.

[0030] To improve the stability of the backlight component 3, the limiting component 8 is configured as a ring structure, and correspondingly, the mounting groove 41 is also configured as a ring. For example, when the backlight component 3 is rectangular, the limiting component 8 is configured as a square ring; when the backlight component 3 is circular, the limiting component 8 is configured as a circular ring. Preferably, the limiting component 8 is also made of metal to improve its structural strength. For example, the limiting component 8 is an iron frame, which is thin and easy to process. As for the first connecting component 6, it can be configured as a ring structure or multiple components can be spaced apart on the limiting component 8. In this embodiment, considering the processing cost and the connection stability between the limiting component 8 and the transparent cover plate 1, multiple first connecting components 6 are spaced apart along the circumference of the limiting component 8. Specifically, the first connecting component 6 and the limiting component 8 can be glued together, or the first connecting component 6 can be welded to the limiting component 8.

[0031] The first connector 6 can also be bonded to the transparent cover 1, which can facilitate the disassembly and assembly of the transparent cover 1 when the display device needs maintenance, without affecting the service life of the transparent cover 1.

[0032] Understandably, the limiting member 8 and the first connecting member 6, located within the mounting groove 41, form a lever structure with a fulcrum. To further enhance the limiting stability of the limiting member 8 on the backlight member 3, the first connecting member 6 is located on the side of the limiting member 8 near the inner wall of the housing 4. More specifically, the first connecting member 6 abuts against the inner wall surface of the housing 4.

[0033] In this embodiment, the backlight component 3 includes multiple stacked backlight films. To ensure that the backlight component 3 can be placed within the limiting space, the distance between the limiting member 8 and the bottom wall of the housing 4 is greater than or equal to the thickness of the backlight component 3. Furthermore, to prevent the limiting member 8 from abrading the backlight films, the distance between the limiting member 8 and the bottom wall of the housing 4 can be slightly greater than the thickness of the backlight component 3, that is, the limiting member 8 does not make close contact with the upper surface of the backlight component 3.

[0034] Continue to refer to Figure 1 As shown, in order to improve the assembly stability between the transparent cover plate 1 and the housing 4, an annular limiting groove 42 is also formed on the inner wall of the housing 4. The opening of the limiting groove 42 faces the transparent cover plate 1 and the limiting groove 42 is located outside the ring of the mounting groove 41. The transparent cover plate 1 is limited to the limiting groove 42. The limiting groove 42 also serves to prevent glue overflow.

[0035] refer to Figures 2-3As shown, the display assembly 2 includes a display screen 21 and a first circuit board 22. The display screen 21 uses an LCD screen, which has high clarity and a long service life. The first circuit board 22 is fixedly disposed on the side of the display screen 21 facing the backlight component 3. The display device also includes a second circuit board 5, which is disposed on the side of the housing 4 facing away from the backlight component 3. The first circuit board 22 and the second circuit board 5 are electrically connected. Specifically, the first circuit board 22 is a flexible circuit board with good bendability, and the second circuit board 5 is a printed circuit board.

[0036] Normally, the pins on the first circuit board 22 used to connect to the second circuit board 5 need to bypass the housing 4, occupying a certain amount of space on the side of the housing 4. This is also the reason why the limiting member 9 is difficult to retract in existing displays. In this embodiment, in order to eliminate the influence of the connection between the first circuit board 22 and the second circuit board 5 on the bezel width of the display device, a through hole 43 is provided on the housing 4. The first circuit board 22 is electrically connected to the second circuit board 5 through the second connector 7 passing through the through hole 43.

[0037] In this embodiment, to reduce manufacturing costs, the second connector 7 is a pin of the first circuit board 22. After being bent, the pin passes through the through hole 43 and is electrically connected to the second circuit board 5. Specifically, considering the thickness of the pin of the first circuit board 22, in order to reduce the difficulty of the pin of the first circuit board 22 passing through the through hole 43, the width of the through hole 43 is not less than 1.3mm. However, if the width of the through hole 43 is too large, it will affect the structural strength of the housing 4. Therefore, the width of the through hole 43 is not greater than 1.9mm.

[0038] In other embodiments, the second connector 7 may also be a separately provided conductor, which is connected to the first circuit board 22 and the second circuit board 5 by means including but not limited to adhesive bonding and welding.

[0039] refer to Figure 3 As shown, the through hole 43 partially penetrates the mounting groove 41, and another portion penetrates the bottom of the limiting groove 42. It can be understood that, in order to avoid interference between the limiting member 8 and the pins of the first circuit board 22, the limiting member 8 has an clearance groove at the position corresponding to the through hole 43, and the first connector 6 and the clearance groove are offset in the circumferential direction of the limiting member 8.

[0040] In summary, based on the existing size of large-size in-vehicle LCD screens (≥20 inches), the bezel of the entire display device can be reduced to 4.9mm on the side of the housing 4 with the through hole 43, and to 3.9mm on the side without the through hole 43, so that the screen ratio of the display device can reach more than 92%.

[0041] This embodiment also proposes a vehicle, including a body and the aforementioned display device. The display device is installed on the vehicle body as an in-vehicle device, which can bring a greater visual impact to the user and enhance the user's driving experience.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
