Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an in-vehicle display device. Background Technology

[0002] Currently, most vehicles are equipped with in-vehicle displays that can show users text, images, and videos. For example, in-vehicle displays can show navigation-related information to help drivers navigate the vehicle.

[0003] Existing vehicle-mounted display devices typically include a display module, a cover plate, and a rear cover. The display module is housed within the rear cover, and the cover plate is positioned over the opening of the rear cover. However, the cover plate of existing vehicle-mounted display devices is prone to lifting or peeling off after being connected to the rear cover, affecting the normal operation of the display device. Summary of the Invention

[0004] This application provides a vehicle-mounted display device to solve the problem that the cover plate of existing vehicle-mounted display devices is prone to floating or peeling off after being connected to the rear cover.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides an in-vehicle display device, which includes a cover plate, a support member, a display module, a first adhesive layer, a backlight module, and a rear cover. The support member is located on one side of the cover plate and connected to it. The first adhesive layer is located between the cover plate and the support member, connected to the cover plate on one side and the support member on the other. The first adhesive layer has a clearance opening, and the support member, the first adhesive layer, and the cover plate form an accommodating space. The display module is disposed within the accommodating space and is connected only to the cover plate. The backlight module is connected to the support member and located on the side of the support member away from the display module. The rear cover is connected to the support member.

[0007] The vehicle-mounted display device provided in this application embodiment has a backlight module connected to a support member, located on the side of the support member away from the display module. This means that thickness errors in the backlight module do not affect the connection between the cover plate and the support member; the connection is only affected by the thickness of the display module. Compared to traditional connection methods, the connection between the cover plate and the support member is less affected by various factors. During the assembly of the vehicle-mounted display device, when the actual thickness of both the display module and the backlight module is larger than the standard thickness, compared to traditional connection methods, the cover plate in this application solution is only affected by the display module error, resulting in a smaller gap between the cover plate and the support member. Consequently, the deformation after the cover plate is connected to the support member is smaller, and the reaction force generated by the cover plate deformation is also smaller, making it less likely for the connection between the cover plate and the support member to separate.

[0008] Because the first adhesive layer is located between the cover plate and the support member, it can be connected only to the side of the support member and the cover plate that is close to each other, without extending onto the peripheral walls of the cover plate or the support member. Consequently, there is no need to provide a structure on the periphery of the display module on the back cover for connecting to the first adhesive layer, which can reduce the frame thickness on the periphery of the display module and thus achieve a narrow bezel effect.

[0009] In some embodiments, a first receiving groove is formed on the surface of the support member near the cover plate, and the display module is disposed in the first receiving groove.

[0010] In some embodiments, the vehicle-mounted display device further includes a second adhesive layer. The second adhesive layer is disposed between the display module and the cover plate, with one side bonded to the display module and the other side bonded to the cover plate.

[0011] In some embodiments, the length of the support member is greater than or equal to the length of the cover plate.

[0012] In some embodiments, the width of the support member is greater than or equal to the width of the cover plate.

[0013] In some embodiments, a connecting groove is provided on the side of the support member away from the cover plate, and the backlight module is inserted into the connecting groove.

[0014] In some embodiments, a limiting part is provided in the connecting groove, and the backlight module is detachably connected to the limiting part.

[0015] In some embodiments, the limiting part is a limiting groove, which is disposed on the peripheral wall of the connecting groove. The backlight module includes a backlight module body and a snap-fit ​​part. The backlight module body is inserted into the connecting groove. The snap-fit ​​part is disposed on the peripheral side of the backlight module and snaps into the limiting groove.

[0016] In some embodiments, the back cover is provided with a protective cavity with an opening, and the backlight module is located on the side of the support member near the bottom wall of the protective cavity.

[0017] In some embodiments, the support member is provided with a connecting portion, and the rear cover is provided with a clearance hole. The vehicle display device also includes a mounting member, which passes through the clearance hole, with one end connected to the connecting portion and the other end connected to the rear cover.

[0018] In some embodiments, the support member is provided with a snap-fit ​​member, and the rear cover is provided with a snap-fit ​​groove, and the snap-fit ​​member snaps into the snap-fit ​​groove. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "center", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more.

[0029] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] In-vehicle display devices in related technologies typically include a display module, a cover plate, and a rear cover. The rear cover has a mounting slot for storing the display module. The display module typically includes a display screen module and a backlight module.

[0032] During the assembly of the vehicle display device, the workers usually first connect the display module and the backlight module together to form the display module, and then connect the display module to the cover plate with special adhesive to form the playback module. Finally, the playback module is connected to the back cover.

[0033] When the playback module is connected to the back cover, the display module and the backlight module are located in the mounting groove, and the cover plate is placed on the groove opening of the mounting groove and bonded to the back cover.

[0034] Due to manufacturing variations in the thickness of the display screen and backlight module, and the fact that the cover plate and display module are connected by adhesive, the thickness of the adhesive layer also varies. Therefore, the overall thickness of the protective cover plate, display screen, and backlight module when joined together may exceed the designed thickness.

[0035] In this way, when the display module and the backlight module are inserted into the mounting slot on the back cover, when the backlight module abuts against the bottom of the mounting slot, there may be a certain gap between the cover plate and the back cover. After the cover plate and the back cover are glued together, the connection between the cover plate and the back cover will undergo a certain deformation, which will cause the cover plate to have a reaction force in the direction away from the back cover, making it easy for the connection between the cover plate and the back cover to separate.

[0036] Based on this, this application provides an in-vehicle display device 100, such as... Figure 1 As shown, Figure 1This is one of the structural schematic diagrams of an in-vehicle display device 100 provided in an embodiment of this application. The in-vehicle display device 100 may include a cover plate 1, a support member 2, a first adhesive layer 7, and a display module 3. The support member 2 is located on one side of the cover plate 1. The first adhesive layer 7 is located between the cover plate 1 and the support member 2. One side of the first adhesive layer 7 is connected to the cover plate 1, and the other side is connected to the support member 2. An avoidance opening 71 is provided on the first adhesive layer 7. The support member 2, the first adhesive layer 7, and the cover plate 1 form an accommodating space, and the display module 3 is disposed within the accommodating space and is only connected to the cover plate 1.

[0037] In practical applications, the first adhesive layer 7 can bond the cover plate 1 to the support member 2, thereby connecting the cover plate 1 and the support member 2 together, so that the support member 2 can support the cover plate 1. The accommodating space formed by the support member 2, the first adhesive layer 7, and the cover plate 1 can provide a setting position for the display module 3, thereby fixing the position of the display module 3.

[0038] Since the first adhesive layer 7 is provided with a clearance opening 71, in actual application, the clearance opening 71 can make way for the display module 3 so that the display module 3 can be connected to the cover plate 1.

[0039] Understandably, the display module 3 can display graphic and textual information to the user. In addition, the display module 3 can also integrate touch sensing functionality to allow the user to interact with the in-vehicle display device 100.

[0040] like Figure 1 As shown, the vehicle-mounted display device 100 may also include a backlight module 4. The backlight module 4 can provide a light source for the display module 3 so that the display module 3 can obtain uniform and sufficient brightness, making the image on the display module 3 clearly visible.

[0041] Continue to refer to Figure 1 The backlight module 4 is connected to the support 2 and is located on the side of the support 2 away from the display module 3.

[0042] In practical applications, since the backlight module 4 is connected to the support member 2, it is located on the side of the support member 2 away from the display module 3. In this way, the thickness error of the backlight module 4 will not affect the connection between the cover plate 1 and the support member 2. The connection between the cover plate 1 and the support member 2 is only affected by the thickness of the display module 3. Compared with the traditional connection method, the connection between the cover plate 1 and the support member 2 is less affected by factors.

[0043] During the assembly of the vehicle-mounted display device 100, when the actual thickness of both the display module 3 and the backlight module 4 is larger than the standard thickness, compared with the traditional connection method, in this application, the cover plate 1 is only affected by the error of the display module 3, and the gap between the cover plate 1 and the support member 2 is smaller. Correspondingly, the deformation of the cover plate 1 after connecting with the support member 2 is smaller, and the reaction force generated by the deformation of the cover plate 1 is also smaller, thus making it less likely for the connection between the cover plate 1 and the support member 2 to separate.

[0044] Continue to refer to Figure 1 The vehicle-mounted display device 100 may also include a rear cover 5. The rear cover 5 is connected to the support member 2. In practical applications, the rear cover 5 can be connected to the mounting structure on the vehicle. In this way, after the support member 2 is connected to the rear cover 5, the support member 2 and components such as the cover plate 1, display module 3, and backlight module 4 connected to the support member 2 can be fixed to the vehicle body.

[0045] In practical applications, since the first adhesive layer 7 is located between the cover plate 1 and the support member 2, the first adhesive layer 7 can only be connected to the side of the support member 2 and the cover plate 1 that are close to each other, and the first adhesive layer 7 will not extend to the peripheral wall of the cover plate 1 or the support member 2. Accordingly, the back cover 5 does not need to have a structure on the periphery of the display module 3 for connecting with the first adhesive layer 7, which can reduce the frame thickness on the periphery of the display module 3, thereby achieving a narrow bezel effect.

[0046] For example, the first adhesive layer 7 can be made of high-adhesion double-sided tape. In this way, the first adhesive layer 7 can have sufficient adhesive strength. At the same time, the high-adhesion double-sided tape also has excellent weather resistance, as well as good impact resistance and shock resistance, which can prevent the cover plate 1 and the support member 2 from separating from each other due to vibrations generated during vehicle operation.

[0047] Understandably, compared to existing solutions connecting the cover plate and the rear cover, the connection between the cover plate 1 and the support member 2 in this application is less affected by various factors, and the reaction force on the cover plate 1 is smaller. Accordingly, when designing the cover plate 1 and the support member 2, the bonding area between them can be appropriately reduced, thereby decreasing the bezel size of the support member 2 on the periphery of the display module 3, achieving a narrow bezel design. This results in a larger screen-to-body ratio for the vehicle display device 100, improving the user experience.

[0048] Furthermore, the display module 3 of this application is disposed within the receiving space formed by the support member 2, the cover plate 1, and the first adhesive layer 7, rather than within the receiving space formed by the back cover in the prior art. The back cover 5 of this application does not require a structure for connecting to the display module 3, which can reduce the edge thickness of the back cover and thus achieve a narrow bezel effect.

[0049] In some embodiments, such as Figure 1 As shown, the length of the support member 2 can be greater than or equal to the length of the cover plate 1. In practical applications, after the cover plate 1 and the support member 2 are connected together, the cover plate 1 will not extend beyond the support member 2 in the length direction. In this way, along the length direction of the vehicle display device 100, there is no need to reserve a structure for connecting with the cover plate 1 on the rear cover 5, which can reduce the narrow bezel design in the length direction of the vehicle display device 100.

[0050] In some embodiments, such as Figure 1 As shown, the width of the support member 2 can be greater than or equal to the width of the cover plate 1. In practical applications, after the cover plate 1 and the support member 2 are connected together, the cover plate 1 will not extend beyond the support member 2 in the width direction. In this way, along the width direction of the vehicle display device 100, there is no need to reserve a structure for connecting with the cover plate 1 on the rear cover 5, which can reduce the narrow bezel design in the width direction of the vehicle display device 100.

[0051] In some embodiments, such as Figure 1 As shown, the back cover 5 may be provided with a protective cavity 51 with an opening, and the backlight module 4 is located on the side of the support member 2 near the bottom wall of the protective cavity 51. In actual application, the backlight module 4 can be inserted into the protective cavity 51, and the protective cavity 51 can protect the backlight module 4.

[0052] Since the backlight module 4 is located on the side of the support member 2 near the bottom wall of the protective cavity 51, the display module 3 and the cover plate 1 can be located on the side of the support member 2 facing the opening of the protective cavity 51. In this way, the back cover 5 will not affect the display module 3 from displaying graphic information to the user.

[0053] For example, such as Figure 2 As shown, Figure 2 This is the second structural schematic diagram of the vehicle-mounted display device 100 provided in the embodiments of this application, showing the mounting component 2. Figure 1 It can be inserted into the protective cavity 51, which can protect the components located inside it.

[0054] In some embodiments, the support member 2 can be placed over the opening of the protective cavity 51. In this way, the edge of the rear cover 5 will not extend to the side of the support member 2 near the cover plate 1, which can reduce the perimeter of the cover plate 1 to achieve a narrow border effect.

[0055] In some embodiments, the support member 2 may be provided with a connecting portion, and the rear cover 5 may be provided with a corresponding clearance hole. The vehicle display device 100 may also include a mounting member, which passes through the clearance hole, with one end connected to the connecting portion and the other end connected to the rear cover 5. In this way, the rear cover 5 and the support member 2 can be connected together by the mounting member.

[0056] For example, such as Figure 3 As shown, Figure 3 The third schematic diagram of the vehicle display device 100 provided in this application embodiment shows that the support member 2 has a connecting portion protruding towards the rear cover 5 on the side near the rear cover 5, and a threaded hole 24 can be provided on the connecting portion. The rear cover 5 has a connecting groove protruding away from the support member 2, and the connecting portion is inserted into the connecting groove. A clearance hole is provided on the connecting groove. The mounting member can be a bolt 8, which passes through the clearance hole and is threadedly connected to the threaded hole 24. The end of the bolt 8 abuts against the side of the connecting groove away from the support member 2, so that the rear cover 5 and the support member 2 are connected together.

[0057] This ensures the stability of the connection between the support component 2 and the back cover 5. Furthermore, by removing the bolts 8, the staff can separate the support component 2 from the back cover 5, making it easier for them to repair the backlight module 4 and the display module 3.

[0058] Understandably, the extension direction of the threaded hole 24 can be perpendicular to the rear cover 5. This allows the operator more operating space when inserting the bolt 8 into the threaded hole 24, making installation more convenient.

[0059] In some embodiments, such as Figure 3 As shown, the support member 2 is provided with a snap-fit ​​member 21, and the rear cover 5 is provided with a snap-fit ​​groove, into which the snap-fit ​​member snaps into the snap-fit ​​groove. In this way, the support member 2 and the rear cover 5 can also be connected together.

[0060] In some embodiments, such as Figure 3 As shown, the support member 2 is close to the protective cavity 51. Figure 1 Multiple snap-fit ​​pieces 21 can be provided on one side of the bottom wall. Correspondingly, multiple snap-fit ​​grooves can be provided on the side wall and bottom wall of the protective cavity 51. The snap-fit ​​pieces 21 can snap into the snap-fit ​​grooves, thereby connecting the support piece 2 and the rear cover 5 together.

[0061] Understandably, in practical applications, the support member 2 can be equipped with both the snap-fit ​​member 21 and the connecting part, or one of them can be selected. Correspondingly, the back cover 5 can be adjusted according to the structure provided on the support member 2 to ensure that the two can be adapted to each other.

[0062] In some embodiments, the orientation of both the snap-fit ​​member 21 and the snap-fit ​​slot can be perpendicular to the rear cover 5. This facilitates the connection of the rear cover 5 to the support member 2 by the operator.

[0063] It should be noted that in practical applications, the back cover 5 can also be connected to the support member 2 in other ways, as long as the stability of the connection is ensured. For example, the back cover 5 can also be connected to the support member 2 by adhesive bonding.

[0064] In some embodiments, such as Figure 1 As shown, the support member 2 has a first receiving groove 22 on the surface near the cover plate 1, and the display module 3 is disposed in the first receiving groove 22.

[0065] In practical applications, the first receiving groove 22 can serve as a receiving space to allow space for the display module 3. In this way, the operator can place the display module 3 in the first receiving groove 22, so that the side of the cover plate 1 near the support member 2 can fit against the surface of the support member 2, making it easier for the operator to connect the cover plate 1 and the support member 2 together.

[0066] In practical applications, after the display module 3 is inserted into the first receiving groove 22, the first receiving groove 22 can form a limit on the periphery of the display module 3, thereby limiting the position of the display module 3 and ensuring the stability of the display module 3.

[0067] Understandably, the first receiving groove 22 can be slightly larger than the thickness of the display module 3 in the depth direction. In this way, when the thickness of the display module 3 is slightly larger than the standard size, the display module 3 can still be fully inserted into the first receiving groove 22, so that the cover plate 1 can fit against the support member 2.

[0068] In other embodiments, the support member 2 may have a protrusion formed in the direction close to the cover plate 1, and the cover plate 1 is connected to the protrusion on the support member 2, forming an accommodating space between the cover plate 1 and the side of the support member 2 close to the cover plate 1. In this way, space can also be provided for the display module 3.

[0069] In some embodiments, such as Figure 1 As shown, the vehicle-mounted display device 100 may further include a second adhesive layer 6, which is disposed between the display module 3 and the cover plate 1, with one side bonded to the display module 3 and the other side bonded to the cover plate 1. In this way, workers can bond the display module 3 and the cover plate 1 together using the second adhesive layer 6.

[0070] For example, the second adhesive layer 6 can be a liquid optically transparent adhesive layer. In this way, the second adhesive layer 6 has good adhesion, ensuring the stability of the connection between the display module 3 and the cover plate 1. At the same time, the second adhesive layer 6 can also have good light transmittance, ensuring that the user can clearly view the graphic and text information displayed on the display module 3.

[0071] In some embodiments, the length of the second adhesive layer 6 may be less than or equal to the length of the display module 3, and the width of the second adhesive layer 6 may be less than or equal to the width of the display module 3. This prevents the second adhesive layer 6 from extending to the periphery of the display module 3. Consequently, no adhesive structure may be provided on the periphery of the display module 3, facilitating the connection of the second adhesive layer 6 to the display module 3 by the operator.

[0072] In some embodiments, such as Figure 3 As shown, a connecting groove 231 is provided on the side of the support member 2 away from the cover plate 1, and the backlight module 4 is inserted into the connecting groove 231. In actual application, after the backlight module 4 is inserted into the connecting groove 231, the peripheral wall of the connecting groove 231 can restrict the backlight module 4, thereby ensuring the stability of the connection between the backlight module 4 and the support member 2.

[0073] In some embodiments, a limiting part 232 is provided in the connecting groove 231, and the backlight module 4 is detachably connected to the limiting part 232. In practical applications, the limiting part 232 can restrict the backlight module 4 so that the backlight module 4 can be stably placed in the connecting groove 231.

[0074] Since the backlight module 4 is detachably connected to the limiting part 232, when the backlight module 4 needs to be repaired or replaced, the staff can separate the backlight module 4 from the limiting part 232 and take the backlight module 4 out of the connecting groove 231.

[0075] To achieve a detachable connection between the backlight module 4 and the limiting part 232, in some embodiments, such as Figure 4 As shown, Figure 4 This is a partial structural diagram of the vehicle-mounted display device 100 provided in this application embodiment. The limiting part 232 can be a limiting groove, which can be disposed on the peripheral wall of the connecting groove 231. The backlight module 4 can include a backlight module body 41 and a snap-fit ​​part 42. The backlight module body 41 is inserted into the connecting groove 231, and the snap-fit ​​part 42 is disposed on the peripheral side of the backlight module body 41 and snaps into the limiting groove.

[0076] In this way, the backlight module 4 and the limiting part 232 can be detachably connected by the snap-fit ​​part 42 and the limiting part 232. In practical applications, since the limiting part is set on the peripheral wall of the connecting groove 231 and the snap-fit ​​part 42 is set on the peripheral side of the backlight module body 41, the setting of the snap-fit ​​part 42 and the limiting part 232 will not increase the dimension of the vehicle display device 100 in the thickness direction.

[0077] In other embodiments, the limiting groove can be disposed on the bottom wall of the connecting groove 231, and correspondingly, the snap-fit ​​part 42 can be disposed on the side of the backlight module body 41 near the bottom wall of the connecting groove 231. In this way, the snap-fit ​​part 42 can also snap into the limiting groove.

[0078] It is understood that the backlight module 4 can also be detachably connected to the limiting part 232 in other ways. For example, the backlight module 4 can be magnetically attached to the connecting groove 231. Alternatively, the backlight module 4 can be screwed into the connecting groove 231.

[0079] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
