Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display device and a vehicle. Background Art

[0002] An in-vehicle display device is an indispensable display device in a vehicle. An in-vehicle floating screen is a development trend and aesthetic preference of in-vehicle display devices. The in-vehicle floating screen includes a detachable decorative rear cover and a plug cover. The decorative rear cover and the plug cover usually require the same appearance. The existing decorative rear cover and plug cover are mostly made of plastic parts and are connected by snap fits. However, this assembly method requires high precision, and the snap fit mostly uses internal snap fits. If the fitting clearance is small, it is difficult to assemble and disassemble, which is not conducive to on-line operation and repair by operators; if the fitting clearance is large, due to the relatively high rigidity of the plastic material, it is easy to move, collide, and rub when the material is stressed, thus easily generating abnormal noises and sounds, making it very inconvenient to use. Summary of the Invention

[0003] The present invention provides a display device and a vehicle to solve the problems that the rear cover and the plug cover of the display device are not easy to assemble and disassemble, and the stability after assembly is not high, and abnormal noises are generated.

[0028] As Figures 1 to 9 shown, the present invention discloses a display device. Specifically, as Figure 1 shown, the display device includes a rear cover 100, a plug cover 200, and a display screen 500. The rear cover 100 is the main appearance part of the display device and is mainly used to install the display screen 500. A hollowed-out area is provided on the rear cover 100, and the display screen 500 is arranged in the hollowed-out area. The display screen 500 installed in the hollowed-out area can block the hollowed-out area and expose the display surface of the display screen 500. One end of the rear cover 100 forms a hollowed-out area, and the other end is open. A straight arm 600 is provided on the non-display surface of the display screen 500. The straight arm 600 extends towards the opening and needs to be connected to the main body of the vehicle by screws. An installation hole 110 is also provided on the rear cover 100. The plug cover 200 is detachably installed in the installation hole 110. By removing the plug cover 200, the installation hole 110 can be opened. Users can very conveniently install screws through the opened installation hole 110. Installing the plug cover 200 into the installation hole 110 can block the installation hole 110 and block the screws, thereby helping to improve the aesthetics and dust-proof performance of the entire display device.

[0029] In an embodiment of the present invention, the plug cover 200 and the rear cover 100 are cooperated in a plug-in manner. Specifically, the plug cover 200 includes a plug-in portion 210, and the plug-in portion 210 can be inserted into the installation hole 110. Optionally, the plug-in portion 210 can be a ring plate structure or a columnar structure. As Figure 2 shown, in some embodiments, the plug cover 200 further includes a cover plate portion 220. The plug-in portion 210 is arranged on the cover plate portion 220. The outer dimension of the cover plate portion 220 is larger than the outer dimension of the plug-in portion 210. When the plug-in portion 210 is inserted into the installation hole 110, the cover plate portion 220 can cover the installation hole 110, which is beneficial to further improve the aesthetics and dust-proof performance. Optionally, the installation hole 110 is a stepped hole and specifically includes a large hole section with a larger size and a small hole section with a smaller size. A stepped surface is formed between the large hole section and the small hole section. The cover plate portion 220 is placed in the large hole section and overlaps on the stepped surface, and the plug-in portion 210 is placed in the small hole section. Further optionally, the depth of the large hole section is equal to the thickness of the cover plate portion 220, so that after the plug cover 200 and the rear cover 100 are plugged in, the appearance surface of the plug cover 200 is flush with the appearance surface of the rear cover 100, which is beneficial to further improve the appearance aesthetics of the display device.

[0030] The display device further includes an elastic structure, which is used to be installed between the plug-in portion 210 and the part of the rear cover 100 where the mounting hole 110 is formed. Specifically, a first mounting area is formed within the mounting hole 110, and a second mounting area is formed on the plug-in portion 210. The elastic structure is disposed in the first mounting area and / or the second mounting area. The plug-in portion 210 of the plug cover 200 is detachably assembled into the mounting hole 110 by squeezing the elastic structure. Compared with the prior art in which both the plug cover and the rear cover are plastic parts and the assembly method is to hard-squeeze two plastic parts and finally complete the snap connection, the elastic structure adopted by the display device provided by the present invention has a larger deformation when compressed than that of a plastic part. The plug cover 200 is detachably assembled into the mounting hole 110 of the rear cover 100 by squeezing the elastic structure. The assembly method of squeezing the elastic structure to achieve assembly makes the plug cover 200 and the rear cover 100 not only easy to disassemble and assemble, but also not likely to generate abnormal noises after assembly, have high stability, and are not likely to become detached.

[0031] It should be noted that in some embodiments, the first mounting area is the side wall of the rear cover 100, and the side wall encloses the mounting hole 110. The second mounting area is the outer wall surface of the plug-in portion 210, and the outer wall surface encloses a ring-shaped second mounting area.

[0032] Regarding the number of the elastic structures, it can be one or two, and the present invention does not make specific limitations. In a specific embodiment, there is one elastic structure, and the elastic structure is installed in the first mounting area. Move the plug cover 200 towards the mounting hole 110. During the process of inserting the plug-in portion 210 of the plug cover 200 into the mounting hole 110, the plug-in portion 210 can squeeze the elastic structure, so that the plug-in portion 210 can smoothly enter the mounting hole 110. After the insertion is completed, the elastic structure partially rebounds, so that the plug cover 200 and the rear cover 100 are fully constrained and stably assembled.

[0033] In another specific embodiment, there is one elastic structure, and the elastic structure is installed in the second mounting area. Move the plug cover 200 towards the mounting hole 110. The plug cover 200 can move synchronously with the elastic structure. During the process of inserting the plug-in portion 210 of the plug cover 200 into the mounting hole 110, the inner wall of the mounting hole 110 can squeeze the elastic structure, so that the plug-in portion 210 can smoothly enter the mounting hole 110. After the insertion is completed, the elastic structure partially rebounds, so that the plug cover 200 and the rear cover 100 are fully constrained and stably assembled.

[0034] In yet another specific embodiment, there are two elastic structures, one of which is disposed in the first installation area and the other is disposed in the second installation area. During the process of inserting the insertion portion 210 of the plug cover 200 into the installation hole 110, the two elastic structures can be cross-misaligned and mated, or the two elastic structures can be overlapped and squeezed to cooperate, so that the insertion portion 210 can smoothly enter the installation hole 110. After the insertion is completed, the elastic structure partially rebounds, so that the plug cover 200 and the rear cover 100 are stably assembled.

[0035] Regarding the structure of the elastic structure, in one specific embodiment, as Figure 3 shown, the elastic structure is disposed in the first installation area. The elastic structure includes a first elastic ring member 300 provided on the side wall. It should be noted that in the embodiments of the present invention, the specific shape of the first elastic ring member 300 is not limited, and it can be a runway-shaped ring, a triangular ring, a rectangular ring, a circular ring, or other shaped rings.

[0036] In another specific embodiment, continue to refer to Figure 2 shown, the elastic structure is disposed in the second installation area. The elastic structure includes a second elastic ring member 400 disposed in the second installation area. The second elastic ring member 400 is sleeved outside the insertion portion 210. It should be noted that in the embodiments of the present invention, the specific shape of the second elastic ring member 400 is not limited, and it can be a runway-shaped ring, a triangular ring, a rectangular ring, a circular ring, or other shaped rings.

[0037] In yet another specific embodiment, one of the two elastic structures is disposed in the first installation area and the other is disposed in the second installation area. The elastic structure disposed in the first installation area is defined as the first elastic structure, and the elastic structure disposed in the second installation area is defined as the second elastic structure. Optionally, the first elastic structure can be the first elastic ring member 300, and the second elastic structure can be the second elastic ring member 400. During the insertion and mating process, the first elastic ring member 300 and the second elastic ring member 400 are stacked in a direction perpendicular to the insertion direction.

[0038] Further optionally, the surface of the first elastic ring member 300 that cooperates with the second elastic ring member 400 is defined as the first ring surface, and the surface of the second elastic ring member 400 that cooperates with the first elastic ring member 300 is defined as the second ring surface. The first ring surface is a ring surface that inclines inwardly toward the installation hole 110 in the insertion direction, while the second ring surface is a ring surface that inclines outwardly toward the insertion portion 210 in the insertion direction. That is, the longitudinal cross-sections of the first elastic ring member 300 and the second elastic ring member 400 are both wedge-shaped surfaces. The sliding cooperation between the first elastic ring member 300 and the second elastic ring member 400 is beneficial to improving the smoothness of insertion. After the first elastic ring member 300 and the second elastic ring member 400 are assembled, the two inclined ring surfaces achieve surface contact, which is beneficial to improving the sealing performance between the plug cover 200 and the rear cover 100.

[0039] Further optionally, the first elastic ring 300 and the second elastic ring 400 are respectively made of materials with different elastic coefficients. One of the first elastic ring 300 and the second elastic ring 400 is made of a material with a larger elastic coefficient, and the other of the first elastic ring 300 and the second elastic ring 400 is made of a material with a smaller elastic coefficient. Such cooperation is conducive to reducing the friction resistance between the two, thereby ensuring smooth assembly.

[0040] In another specific embodiment, one of the two elastic structures is arranged in the first installation area, and the other is arranged in the second installation area. The elastic structure arranged in the first installation area is defined as the first elastic structure, and the elastic structure arranged in the second installation area is defined as the second elastic structure. In this embodiment, the first elastic structure includes a plurality of first elastic members arranged at intervals in the circumferential direction of the installation hole 110, and the second elastic structure includes a plurality of second elastic members arranged at intervals in the circumferential direction of the plug-in portion 210. The first elastic member and the second elastic member are staggered and plugged together to form a ring-shaped elastic member. There is no limit on the number of the first elastic member and the second elastic member, and they can be flexibly adjusted according to needs.

[0041] Continue to refer to Figure 3 As shown, in some embodiments, the first elastic ring 300 includes a first ring body 310 and at least one first protrusion 320, the first ring body 310 has an inner ring surface, the inner ring surface is surrounded to form a first inner hole, and the first protrusion 320 is arranged on the inner ring surface. After the plug-in portion 210 of the plug cover 200 is assembled into the mounting hole 110, the first protrusion 320 and the plug-in portion 210 can form an interference fit at the matching position, and the part of the first ring body 310 where the first protrusion 320 is not arranged can form a clearance fit with the matching position of the plug-in portion 210. The arrangement of the first protrusion 320 makes it easier to find deformation when it is squeezed, and the gap where the first protrusion 320 is not arranged provides space for deformation, so such an arrangement is more conducive to ensuring the smoothness of assembly.

[0042] In a specific embodiment, the first protrusion 320 is extended along the plugging direction of the plug-in portion 210 to the mounting hole 110, which is conducive to reducing the difficulty of plugging. Of course, in other embodiments, according to user needs, the extension direction of the first protrusion 320 can also be set to form an angle with the plugging direction. In another parallel embodiment, such as Figure 4 As shown, the first protrusion 320 is an annular structure and is extended along the circumference of the first ring body 310. The first protrusion 320 is set as an annular structure, which is conducive to improving the sealing performance of the plugging direction of the plugging cover 200 and the back cover 100 after assembly, and preventing water vapor from entering the display device along the plugging direction.

[0043] In a specific embodiment, there are multiple first protrusions 320. If the first protrusions 320 extend along the insertion direction in which the insertion portion 210 is inserted into the mounting hole 110, the multiple first protrusions 320 are spaced circumferentially on the inner circumferential surface; if the first protrusions 320 are in an annular structure, the multiple first protrusions 320 are spaced in the height direction of the inner circumferential surface. The arrangement of the multiple first protrusions 320 is beneficial to further improve the sealing performance. Optionally, the multiple first protrusions 320 are spaced and evenly arranged on the inner circumferential surface.

[0044] In a specific embodiment, the shape of the first cross-section of the first protrusion 320 in a direction perpendicular to its extension direction is circular, triangular or square. Optionally, the cross-sectional shapes of the first cross-sections of the first protrusions 320 in a direction perpendicular to their extension directions are the same. Optionally, the cross-sectional areas of the first cross-sections of the first protrusions 320 in a direction perpendicular to their extension directions are equal or gradually increase along the insertion direction.

[0045] Continue to refer to Figure 2 and Figure 9 As shown, the above-mentioned second elastic ring 400 includes a second ring body portion 410 and at least one second protrusion 420. The second ring body portion 410 is formed with a second inner hole 401. The second ring body portion 410 has an outer circumferential surface formed on the outside of the second inner hole 401, and the second protrusion 420 is provided on the outer circumferential surface. Continue to refer to Figures 5 to 7 As shown, after the insertion portion 210 of the plug cover 200 is assembled into the mounting hole 110, an interference fit can be formed at the mating portion between the second protrusion 420 and the mounting hole 110, and a clearance fit can be formed at the mating portion between the portion of the second ring body portion 410 where the second protrusion 420 is not provided and the mounting hole 110. The setting of the second protrusion 420 makes it easier to find deformation when it is squeezed, and the clearance where the second protrusion 420 is not provided provides space for deformation. Such a setting is more conducive to ensuring the smoothness of assembly.

[0046] In a specific embodiment, the second protrusion 420 extends along the insertion direction in which the insertion portion 210 is inserted into the mounting hole 110. Such a setting is beneficial to reducing the insertion difficulty. Of course, in other embodiments, according to user requirements, the extension direction of the second protrusion 420 can also be set at an angle to the insertion direction. In another parallel embodiment, the second protrusion 420 is in an annular structure and extends along the circumference of the second ring body portion 410. Setting the second protrusion 420 as an annular structure is beneficial to improving the sealing performance in the insertion direction after the plug cover 200 and the rear cover 100 are assembled, and preventing water vapor from entering the interior of the display device along the insertion direction.

[0047] In a specific embodiment, there are multiple second protrusions 420. If the second protrusions 420 extend along the insertion direction in which the insertion part 210 is inserted into the mounting hole 110, the multiple second protrusions 420 are arranged at intervals in the circumferential direction of the inner side surface; if the second protrusions 420 are of an annular structure, the multiple second protrusions 420 are arranged at intervals in the height direction of the inner side surface. The arrangement of the multiple second protrusions 420 is beneficial to further improve the sealing performance. Optionally, the multiple second protrusions 420 are arranged at intervals and evenly on the inner side surface.

[0048] In a specific embodiment, the shape of the second cross-section of the second protrusion 420 in the direction perpendicular to its extension direction is circular, triangular or square. Optionally, the cross-sectional shapes of the second cross-sections of the second protrusions 420 in the direction perpendicular to their extension directions are the same. Optionally, the cross-sectional areas of the second cross-sections of the second protrusions 420 in the direction perpendicular to their extension directions are equal or gradually decrease along the insertion direction.

[0049] It should be noted that if the first elastic ring member 300 and the second elastic ring member 400 exist simultaneously, the first protrusion 320 and the second protrusion 420 can be arranged in a staggered manner to reduce the insertion difficulty.

[0050] To improve the firmness of the elastic structure after being assembled with the rear cover 100 and prevent accidental detachment, in one embodiment, the elastic structure and the rear cover 100 are fixed by insert molding; in another embodiment, the elastic structure and the rear cover 100 are fixed by welding; in yet another embodiment, the elastic structure and the rear cover 100 are fixed by a pasting process. In addition, an embedding groove can also be formed on the side wall of the rear cover 100, and the elastic structure is embedded in the groove to achieve fixation. It should be noted that insert molding is a plastic molding process, also known as insert molding or in-mold molding, which is a molding process of loading a pre-prepared heterogeneous insert into a mold and then injecting molten plastic so that the plastic is joined and cured with the insert to form an integrated product.

[0051] To improve the firmness of the elastic structure after being assembled with the plug cover 200 and prevent accidental detachment, in one embodiment, the elastic structure and the plug cover 200 are fixed by insert molding; in another embodiment, the elastic structure and the plug cover 200 are fixed by welding; in yet another embodiment, the elastic structure and the plug cover 200 are fixed by a pasting process. In addition, an insertion ring groove can also be formed on the annular elastic structure, and the insertion part 210 provided as a ring plate structure is inserted into the insertion ring groove.

[0052] Continue to refer to Figure 8 and Figure 9As shown, in some embodiments, the rear cover 100 includes a main body portion and an annular protruding portion 120 protruding from the main body portion. The annular protruding portion 120 surrounds and forms an installation hole 110. The elastic structure further includes a clamping portion 430, and the clamping portion 430 can be clamped onto the annular protruding portion 120. Clamping the clamping portion 430 onto the annular protruding portion 120 is beneficial to improving the connection strength and connection stability between the rear cover 100 and the plug cover 200.

[0053] Optionally, a plurality of clamping portions 430 are provided. The plurality of clamping portions 430 are spaced apart in the circumferential direction of the main body portion. The plurality of clamping portions 430 can be clamped onto the annular protruding portion 120 simultaneously, which is beneficial to further improving the connection strength and connection stability between the rear cover 100 and the plug cover 200. Further optionally, the plurality of clamping portions 430 are equally spaced in the circumferential direction of the main body. In a specific embodiment, continue to refer to Figure 2 As shown, four clamping portions 430 are provided, and the four clamping portions 430 are respectively arranged on the front side, rear side, left side, and right side of the main body portion.

[0054] Regarding the manufacturing material of the rear cover 100, a rigid material is generally used, such as a plastic part. In one embodiment, the rear cover 100 is a polycarbonate plastic part made of polycarbonate plastic (PC); in another embodiment, the rear cover 100 is an acrylonitrile-butadiene-styrene plastic part made of acrylonitrile-butadiene-styrene plastic (ABS).

[0055] Regarding the manufacturing material of the plug cover 200, a rigid material is generally used, such as a plastic part. In one embodiment, the plug cover 200 is a polycarbonate plastic part made of polycarbonate plastic (PC); in another embodiment, the plug cover 200 is an acrylonitrile-butadiene-styrene plastic part made of acrylonitrile-butadiene-styrene plastic (ABS).

[0056] The rear cover 100 and the plug cover 200 made of a rigid material can ensure the rigidity of the main material of the display device, which is beneficial for appearance modeling, maintaining the modality, and maintaining the natural frequency. The installation area between the rear cover 100 and the plug cover 200 adopts an elastic structure with high elasticity. After the assembly is completed, at least part of the elastic structure (such as the first protruding portion 320 and / or the second protruding portion 420) is compressed and deformed to achieve close fitting and interference fit, thereby realizing the complete engagement of the rear cover 100 and the plug cover 200 and ensuring the stability of the assembly. The cooperation of the rear cover 100 and the plug cover 200 made of a rigid material and the elastic structure made of an elastic material makes the disassembly of the rear cover 100 and the plug cover 200 more convenient.

[0057] Optionally, the rear cover 100 and the plug cover 200 are made of the same material to meet the requirement of material consistency between the rear cover 100 and the plug cover 200, which is beneficial to improving the aesthetics of the entire display device.

[0058] Regarding the manufacturing material of the elastic structure, in one embodiment, the elastic structure is a thermoplastic polyurethane elastomer (TPU) part made of thermoplastic polyurethane elastomer; in another embodiment, the elastic structure is a thermoplastic polyester elastomer (TPEE) part made of thermoplastic polyester elastomer; in yet another embodiment, the elastic structure is a thermoplastic styrene elastomer (TPS) part made of thermoplastic styrene elastomer.

[0059] The present invention also discloses a vehicle, which includes a main body and the above-mentioned display device, and the display device is used as an in-vehicle display device. Optionally, the vehicle can be an automobile, a ship, a subway, a train, an airplane, etc. When the vehicle is an automobile, a train or a subway, the main body is the vehicle body; when the vehicle is a ship, the main body is the hull; when the vehicle is an airplane, the main body is the aircraft body. It should be noted that the structures of the vehicle body, the hull and the aircraft body are all prior arts and will not be described in detail here. By using the above-mentioned display device, the rear cover 100 and the plug cover 200 of the display device are not only convenient to disassemble and assemble, but also have high stability after assembly, are not likely to make abnormal noises, which is beneficial to improving the user experience.

[0060] As can be seen from the above embodiments, the display module and the vehicle provided by the present invention at least achieve the following beneficial effects:

[0061] The display module provided by the present invention includes: a rear cover, on which an installation hole is formed, and a first installation area is formed in the installation hole; a plug cover, the plug cover includes a plug-in part that can be inserted into the installation hole, and a second installation area is formed on the plug-in part; an elastic structure, the elastic structure is arranged in the first installation area and / or the second installation area; a display screen, a hollow area is provided on the rear cover, the display screen is arranged in the hollow area, and the plug cover is detachably assembled in the installation hole by squeezing the elastic structure.
