The present invention discloses a safety structure for a display screen and a vehicle-mounted display device. The safety structure for the display screen includes a mounting seat and a limiting member. The mounting seat has two opposite sides, one side of which is provided with a mounting portion for mounting a display screen assembly. The mounting seat has through holes extending through both sides. There is at least one fixing member, which extends along the thickness direction of the mounting seat, movably passes through the through hole and is spaced apart from the hole wall of the through hole. The fixing member has a connecting end and a limiting end extending from both ends of the through hole. The connecting end is provided corresponding to the mounting portion and is used to connect the display screen assembly. The limiting end is provided with a convex portion protruding toward its circumferential side. The convex portion is spaced apart from the mounting seat to limit the fixing member from moving and separating from the through hole in the direction from the limiting end to the connecting end. In the technical solution of the present invention, the fixing member will only limit the display screen assembly from falling if the display screen assembly is about to fall off accidentally. The display screen assembly is not subjected to force during normal use, thereby reducing the risk of the display screen assembly being easily cracked or damaged.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted display technology, and in particular to a safety structure of a display screen and a vehicle-mounted display device. Background Art

[0002] In-vehicle displays are becoming increasingly common, mostly using LCDs. LCD display technology is relatively mature and can meet the requirements of in-vehicle experimental conditions. At the same time, new demands are being placed on in-vehicle displays, such as thinness, high contrast, and a wide color gamut. OLED displays, previously used in consumer products, are gradually entering the automotive market. They offer all the advantages mentioned above, making them a natural solution. However, OLED displays have their own limitations. They do not require a backlight to provide light and are self-luminous. However, these limitations also hinder the protection and enclosure of structural components. Rigid OLED screens, on the other hand, are made of rigid materials, currently primarily glass, which are not flexible and are prone to cracking and splitting. Therefore, it is particularly important that the screen be free from stress within the structural components and remain suspended.

[0003] Traditional display screen security structures generally involve screw fixation or safety ropes. Screw-locking requires a screw post on the back of the display, and after locking, the screw post is always under stress. This solution is feasible for LCD displays, but not for rigid OLED screens. Safety rope solutions require steel wire rope, which has a certain degree of flexibility, making assembly inconvenient, and can produce abnormal noise if the reserved length is not appropriate. Furthermore, safety ropes are mostly used to protect the assembly. They are fixed to the structural frame and can be locked, which is subject to stress. Summary of the Invention

[0004] The main purpose of the present invention is to provide a safety structure for a display screen, aiming to solve the problem that the existing safety structure may cause the display screen to be subjected to stress and be improperly protected.

[0005] To achieve the above objectives, the safety structure of the display screen proposed by the present invention includes:

[0006] A mounting base having two opposite sides, one side of which is provided with a mounting portion for mounting the display screen assembly, the mounting base having through holes extending through the two sides; and

[0007] A fixing member is provided with at least one, the fixing member extends along the thickness direction of the mounting seat, movably passes through the through hole and is spaced apart from the hole wall of the through hole, the fixing member has a connecting end and a limiting end extending from both ends of the through hole, the connecting end is arranged corresponding to the mounting portion, and is used to connect the display screen assembly, the limiting end is provided with a convex portion protruding toward its circumferential side, the convex portion is spaced apart from the mounting seat, and the convex portion is used to limit the fixing member from moving and separating from the through hole in the direction from the limiting end to the connecting end.

[0008] Optionally, the display screen assembly includes a display screen and a cover plate;

[0009] The mounting portion is used to sequentially mount the display screen and the cover plate in a direction away from the other side of the mounting base.

[0010] Optionally, the fixing member includes a connecting member and a limiting member sequentially arranged along two sides of the mounting seat, the connecting end is formed on the connecting member, and the limiting end is formed on the limiting member;

[0011] The connecting member is detachably connected to the limiting member.

[0012] Optionally, the connecting end is used to connect to the display screen and / or the cover plate;

[0013] The connecting piece is provided with a screw hole in a direction away from the connecting end;

[0014] An end of the limiting member close to the connecting end is provided with an external thread for threaded connection with the screw hole.

[0015] Optionally, the connecting end is used to pass through a gap in the display screen to connect to the cover plate;

[0016] The connecting member comprises at least one connecting post extending toward the limiting end, the connecting post being provided with a buckle groove in a direction away from the connecting end, and the inner side wall of the buckle groove being provided with a snap groove;

[0017] The limiting member includes at least one limiting column extending toward the connecting end, and the limiting column is provided with a buckle that can be extended into the buckle groove at one end close to the connecting end, and a clamping block is protruded from the outer side of the buckle, and the clamping block is engaged with the buckle groove for limiting the position.

[0018] Optionally, there are two connecting posts, and ends of the two connecting posts away from the limiting end are connected to form the connecting end;

[0023] Optionally, the display screen assembly includes a display screen and a cover plate, and the display screen includes a rigid OLED screen.

[0024] In the technical solution of the present invention, when the display screen assembly is normally installed on the mounting seat, since the fixing member is spaced apart from the hole wall of the through hole, and the protrusion protruding from the peripheral side of the limiting end is spaced apart from the mounting seat, the fixing member is not in contact with the mounting seat, and the display screen assembly is not subjected to force. Even if the display screen assembly has bending deformation or warping problems after installation, it will not be subjected to force and cause the screen color to change due to the constraints of the safety structure of the display screen.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

[0040] In-vehicle displays are becoming increasingly common, mostly using LCDs. LCD display technology is relatively mature and can meet the requirements of in-vehicle experimental conditions. At the same time, new demands are being placed on in-vehicle displays, such as thinness, high contrast, and a wide color gamut. OLED displays, previously used in consumer products, are gradually entering the automotive market. They offer all the advantages mentioned above, making them a natural solution. However, OLED displays have their own limitations. They do not require a backlight to provide light and are self-luminous. However, these limitations also hinder the protection and enclosure of structural components. Rigid OLED screens, on the other hand, are primarily made of glass, which is not flexible and prone to cracking and splitting. Therefore, it is crucial that the screen be free from stress within the structural components and remain suspended.

[0041] Traditional display screen security structures generally involve screw fixation or safety ropes. Screw-locking requires a screw post on the back of the display, and after locking, the screw post is always under stress. This solution is feasible for LCD displays, but not for rigid OLED screens. Safety rope solutions require steel wire rope, which has a certain degree of flexibility, making assembly inconvenient, and can produce abnormal noise if the reserved length is not appropriate. Furthermore, safety ropes are mostly used to protect the assembly. They are fixed to the structural frame and can be locked, which is subject to stress.

[0042] In view of this, the present invention proposes a safety structure 100 for a display screen. Figures 1 to 4 This is an embodiment of the safety structure 100 of a display screen provided by the present invention. Figures 5 to 7 This is another embodiment of the safety structure 100 of a display screen provided by the present invention. The present invention solves the problem that the existing safety structure may cause the display screen to be subjected to stress and be improperly protected. The safety structure 100 of the display screen will be described below with reference to specific drawings.

[0043] Reference Figures 1 to 2The safety structure 100 of the display screen includes a mounting base 1 and a fixing member 2, the mounting base 1 having two opposite sides, one side of which is provided with a mounting portion 11 for mounting the display screen assembly 3, the mounting base 1 having a through hole 12 running through both sides, the fixing member 2 having at least one, the fixing member 2 extending along the thickness direction of the mounting base 1, movably passing through the through hole 12 and spaced apart from the hole wall of the through hole 12, the fixing member 2 having a connecting end 21 and a limiting end 22 extending from both ends of the through hole 12, the connecting end 21 being provided corresponding to the mounting portion 11 and being used to connect the display screen assembly 3, the limiting end 22 being provided with a convex portion 221 protruding toward its circumferential side, the convex portion 221 being spaced apart from the mounting base 1, and the convex portion 221 being used to limit the fixing member 2 from moving and separating from the through hole 12 in the direction from the limiting end 22 to the connecting end 21.

[0044] In the technical solution of the present invention, when the display screen assembly 3 is normally installed on the mounting base 1, since the fixing member 2 is spaced apart from the hole wall of the through hole 12, and the protrusion 221 protruding from the side of the limiting end 22 is spaced apart from the mounting base 1, the fixing member 2 does not contact the mounting base 1, and the display screen assembly 3 is not subjected to force. Even if the display screen assembly 3 has bending deformation or warping problems after installation, it will not be subjected to force and cause the screen color to change due to the constraint of the safety structure 100 of the display screen. When a vehicle collision or airbag deployment occurs, generating a strong impact force, and the display screen assembly 3 is at risk of falling off the mounting base 1, the display screen assembly 3 will be displaced a certain amount in the direction away from the mounting base 1, and the fixing member 2 is driven to displace. The protrusion 221 of the limiting end 22 approaches the mounting base 1 to limit the fixing member 2 from continuing to move until it is separated from the through hole 12, thereby limiting the display screen assembly 3 from falling off and preventing the display screen assembly 3 from falling and injuring people.

[0045] It is worth mentioning that, in order not to affect the structural strength of the mounting base 1 , the through hole 12 is provided corresponding to the middle portion of the display screen assembly 3 and avoids the reinforcing ribs provided on the mounting base 1 .

[0046] See also Figure 2 The display screen assembly 3 includes a display screen 31 and a cover plate 32 , and the mounting portion 11 is used to sequentially mount the display screen 31 and the cover plate 32 in a direction away from the other side of the mounting base 1 .

[0047] The specific form of the fixing member 2 is not limited. In other embodiments, the fixing member 2 can be in an integrated form. In this embodiment, the fixing member 2 includes a connecting member 23 and a limiting member 24 arranged in sequence along both sides of the mounting base 1. The connecting end 21 is formed on the connecting member 23, and the limiting end 22 is formed on the limiting member 24. The connecting member 23 and the limiting member 24 are detachably connected. During assembly, the display screen assembly 3 is first connected to the connecting member 23 and then installed on the mounting portion 11. After the installation is completed, the limiting member 24 and the connecting member 23 are assembled on the other side of the mounting base 1. The detachable limiting member 24 is used to complete the assembly without contact between the fixing member 2 and the mounting base 1, and a sufficient safety gap is reserved to avoid the display screen assembly 3 being damaged by force during the assembly process.

[0048] The connection between the fixing member 2 and the display screen assembly 3 is not limited in specific terms. The fixing member 2 can be used to connect the display screen 31 or the cover plate 32 .

[0049] When the fixing member 2 is used to connect the display screen 31, in order to prevent the display screen 31 from being damaged by force during the assembly process of the connecting member 23 and the limiting member 24, in this embodiment, the connecting member 23 has a screw hole 231 in a direction away from the connecting end 21, and the limiting member 24 has an external thread 241 at one end near the connecting end 21 for threaded connection with the screw hole 231. The threaded connection between the limiting member 24 and the connecting member 23 has minimal impact on the display screen 31, making it less susceptible to damage.

[0050] When the fixing member 2 is used to connect the cover plate 32, since the cover plate 32 can be subjected to force relative to the display screen 31, the limiting member 24 and the connecting member 23 can be connected by screw threads or other forms. Figure 5The connecting end 21 is used to pass through the gap 311 of the display screen 31 to connect to the cover plate 32. The connecting member 23 includes at least one connecting column 232 extending toward the limiting end 22. The connecting column 232 is provided with a buckle groove 232a in the direction away from the connecting end 21. The inner side wall of the buckle groove 232a is provided with a buckle groove 232b. The limiting member 24 includes at least one limiting column 242 extending toward the connecting end 21. The limiting column 242 is provided with a buckle 242a at one end close to the connecting end 21, which can be extended into the buckle groove 232a. A block 242b is protruded from the outer side of the buckle 242a, and the block 242b is engaged with the buckle groove 232b to limit the position. During assembly, the cover plate 32 is first connected to the connector 23 and then installed on the mounting portion 11. After installation is completed, the clip 242a of the limiting column 242 is inserted into the clip groove 232a on the other side of the mounting base 1. The clamping block 242b cooperates with the clip groove 232b to engage and limit the position. The clamping structure makes assembly more convenient and quick. In order to ensure that the clip 242a is inserted into the clip groove 232a and the clip block 242b is engaged with the clip groove 232b, the material of the clip block 242b includes an elastic material. When the clip 242a is inserted into the clip groove 232a, the clip block 242b elastically deforms and enters the clip groove 232a. When the clip block 242b enters the clip groove 232b, the deformation is restored to complete the fastening. Furthermore, to meet the structural framework and spatial structure requirements of the mounting base 1 in practical applications, in this embodiment, two connecting posts 232 are provided. The ends of the two connecting posts 232 away from the limiting end 22 are connected to form the connecting end 21. Two limiting posts 242 are provided corresponding to the connecting posts 232. The mounting base 1 is provided with two through holes 12 corresponding to the two connecting posts 232 for their insertion. The specific details of the connecting posts 232 are not limited.

[0051] It should be noted that the fixing member 2 can be used to connect the display screen 31 or to connect the cover plate 32, or multiple fixing members 2 can be provided to exist at the same time. Obviously, the technical effect brought by the simultaneous existence is the best.

[0052] The connection end 21 can be connected to the display screen assembly 3 in a variety of ways, without limitation. To ensure that the connection end 21 does not damage the display screen assembly 3, the connection end 21 extends to the periphery to form an adhesive plate 211. The adhesive plate 211 is used to adhere to the display screen assembly 3. Furthermore, the adhesive plate 211 is provided with a pressure-sensitive adhesive 211a. The pressure-sensitive adhesive 211a is not limited in specific terms and may include VHB tape. The VHB tape has a cushioning function and does not damage the display screen assembly 3. The bonding area and shape of the adhesive plate 211 are not specifically limited. When the adhesive plate 211 is used to bond the display screen 31, the bonding position of the display screen 31 is unobstructed, and the bonding area of ​​the adhesive plate 211 can be expanded according to the required bonding strength. When the adhesive plate 211 is used to bond the cover plate 32, because the connecting end 21 is used to penetrate the gap 311 of the display screen 31 to connect to the cover plate 32, the adhesive plate 211 is located in the gap 311 of the display screen 31 and its size is limited. The size of the adhesive plate 211 must adapt to the gap 311 of the display screen 31. Therefore, the fixing member 2 is provided with multiple members, each connected to the display screen 31 and the cover plate 32, and cooperates with each other to enhance the effect of preventing the display screen assembly 3 from falling in the event of an accident.

[0053] The present invention further provides an in-vehicle display device, comprising a display screen assembly 3 and a display screen safety structure 100. The specific structure of the display screen safety structure 100 is described with reference to the above-described embodiments. Since the present in-vehicle display device utilizes all the technical solutions of all the above-described embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments. A detailed description thereof will not be repeated here.

[0054] It should be noted that, in the present invention, the specific structure of the vehicle-mounted display device is not limited.

[0055] There are many types of display screen components 3, with no specific restrictions. The display screen component 3 includes a display screen 31 and a cover plate 32. The cover plate 32 includes a glass cover plate, and the specific shape is not limited. The display screen 31 includes a rigid OLED screen. The safety structure 100 of the display screen is adapted to the rigid OLED screen. When the rigid OLED screen is normally installed, the fixing part 2 is not subjected to force. Only in the event of an accident, when the rigid OLED screen is about to fall off, the fixing part 2 will restrict the rigid OLED screen from falling, reducing the risk of the rigid OLED screen being easily cracked or damaged. Obviously, in other embodiments, the display screen 31 may also include other different models of the display screen 31 that require a safety structure, and the safety structure 100 of the display screen can still function, with no specific restrictions. In another embodiment, the display screen 31 may include an LCD display screen.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
