Description

Technical Field

[0001] This utility model relates to the field of display screens, and more specifically, to an anti-noise display screen. Background Technology

[0002] Unusual noises are a key consideration in the design of electronic products. Abnormal or unusual sounds produced during the operation of electronic products may originate from internal looseness, friction, vibration, or creep under high or low temperatures. These noises not only affect the user experience but may also indicate potential quality problems. Therefore, detecting and controlling unusual noises is particularly important during the design and manufacturing process of electronic products.

[0003] For display screens, because they are exposed and mounted on the car's center console, they experience a wide range of high and low temperature changes throughout their lifecycle. Additionally, the vibrations generated during vehicle operation make them prone to generating abnormal noises. In related technologies, the various components of display screens are mostly installed using screws and clips, such as connecting the panel and back cover with clips. This connection method has poor stability and is prone to shaking and friction under high and low temperature differences and vibrations, resulting in abnormal noises and affecting the user experience. Utility Model Content

[0004] In view of this, the present invention provides a display screen with anti-noise function, in which the panel and back cover are connected by a fusion structure instead of the traditional snap-fit ​​connection.

[0005] The objective of this utility model is achieved through the following technical solution: An anti-noise display screen includes a front assembly and a rear assembly, the front assembly and the rear assembly being fixedly connected; the front assembly includes a display module, a circuit board and a bracket, the circuit board and the bracket being fixed to the back of the display module; the rear assembly includes a panel and a back cover, the front assembly being fixed to the panel, the panel and the back cover being connected as a whole by multiple welding structures. The welding structure includes welding posts and welding grooves. The welding posts are disposed on the panel and the welding grooves are disposed on the back cover; or, the welding posts are disposed on the back cover and the welding grooves are disposed on the panel. The welding posts pass through the corresponding welding grooves and are fixed in the welding grooves by heat fusion.

[0006] The above technical solution employs a welding post and welding groove mating structure, fixing the welding post into the welding groove via heat fusion. Compared to traditional snap-fit ​​connections, this heat fusion fixing method creates a tight, inseparable whole between the panel and the back cover, greatly enhancing the strength and stability of the connection. During use, regardless of the direction of force applied to the display screen, such as vibration, impact, or slight human shaking, there will be no displacement or shaking. Furthermore, there will be no relative movement caused by mutual compression after shrinkage under high or low temperatures, effectively avoiding abnormal noise problems caused by loose components and providing users with a more stable and quiet user experience.

[0007] Alternatively, in one possible implementation, a plurality of the welded structures are distributed circumferentially at intervals along the panel and the back cover.

[0008] In the above technical solution, multiple welding structures are distributed circumferentially along the panel and the back cover, forming a ring-shaped connection system. This layout can fix the front assembly and the back assembly from all directions, so that the display screen can maintain structural stability when subjected to external forces from different directions.

[0009] Optionally, in one possible implementation, the panel and the back cover are a multi-layered stepped structure that fits together; wherein, at the joint of each stepped surface, a plurality of circumferentially spaced welding structures are provided.

[0010] In the above technical solution, the multi-layered stepped structure provides more contact surfaces and connection points for the connection between the panel and the back cover. Each stepped surface is equipped with a welding structure, which is equivalent to building multiple solid connection defenses in both the vertical and horizontal directions of the display screen. This layered connection method makes the connection between the panel and the back cover tighter and more secure, with each layer supporting and cooperating with each other, greatly enhancing the strength and rigidity of the entire display screen structure.

[0011] Optionally, in one possible implementation, extension plates are further provided on opposite sides of the panel, the back cover is provided with a support base corresponding to the extension plate, and a plurality of the welding structures are provided at the joint between the support plate and the support base.

[0012] In the above technical solution, the extension plate and support base provide additional support for the lateral structure of the display screen, effectively dispersing and bearing lateral forces, and greatly enhancing the overall impact resistance of the display screen. Furthermore, the multiple welded structures at the junction of the extension plate and support base provide stable fixing, making the connection between the panel and the back cover more secure in the lateral direction.

[0013] Alternatively, in one possible implementation, the panel and the back cover are also fixedly connected by a plurality of first screws.

[0014] In the above technical solution, based on the multi-layer stepped structure of the panel and back cover, the cooperation between the extension plate and the support base, and the connection of the fused structure, the rigidity of the entire display screen structure is further enhanced by fixing it with multiple first screws.

[0015] Alternatively, in one possible implementation, the connection between the welding post and the welding groove is a clearance fit or a transition fit.

[0016] In the above technical solution, the welding post and the welding groove adopt a clearance fit or a transition fit, which greatly simplifies the assembly process. With a clearance fit or a transition fit, the welding post can be easily inserted into the welding groove, thus providing reasonable assembly convenience.

[0017] Alternatively, in one possible implementation, the circuit board and the bracket are respectively fixedly connected to the display module by a plurality of second screws.

[0018] In the above technical solution, the fixing connection method using the second screw can accurately position the circuit board and the bracket at the designated location on the display module. Furthermore, using the second screw for fixing connection makes the installation and removal of the circuit board and the bracket simple and quick.

[0019] Alternatively, in one possible implementation, the display module is fixedly attached to the post-assembly by an adhesive.

[0020] In the above technical solution, the adhesive can form a uniform and continuous bonding layer between the display module and the back assembly, tightly bonding the two into a whole. Furthermore, using adhesive for fixing achieves a seamless connection between the display module and the back assembly, effectively preventing dust, moisture, and other impurities from entering the device and protecting the display module and other electronic components from external environmental corrosion.

[0021] Optionally, in one possible implementation, the post-assembly is provided with a plurality of mounting holes, and the bracket communicates with the outside through the mounting holes.

[0022] In the above technical solution, the mounting holes not only facilitate the installation of the bracket and the external structure, but also provide a convenient channel for the internal cable connection of the equipment, allowing the cable to pass through directly, avoiding the complicated winding process and simplifying the wiring design.

[0023] Alternatively, in one possible implementation, the end of the welding post is heat-melted to form a mushroom-shaped structure with a diameter larger than the inlet of the welding groove, and the mushroom-shaped structure is pressed against the periphery of the welding groove.

[0024] In the above technical solution, after the welding column melts, it forms a mushroom-shaped structure on the welding groove. At the same time, the molten part of the welding column fills the gap that mates with the welding groove, thereby forming a seamless hot-melt weld joint. In addition, the mushroom-shaped structure can be firmly embedded into the material around the welding groove like an anchor, effectively preventing the connection from loosening or separating, and greatly enhancing the connection strength between the two components.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0036] Please refer to Figures 1-7 This embodiment provides an anti-noise display screen, including a front assembly and a rear assembly, which are fixedly connected. The front assembly includes a display module 1, a circuit board 2, and a bracket 3. The circuit board 2 and the bracket 3 are both fixed to the back of the display module 1, which is the side of the display module 1 opposite to the rear assembly. The rear assembly includes a panel 4 and a back cover 5. The front assembly is fixed to the panel 4, and the panel 4 and the back cover 5 are connected as one unit by multiple welding structures 6. The welding structure 6 includes welding posts 61 and welding grooves 62. The welding posts 61 are disposed on the panel 4, and the welding grooves 62 are disposed on the back cover 5; or, the welding posts 61 are disposed on the back cover 5, and the welding grooves 62 are disposed on the panel 4. The welding posts 61 pass through the corresponding welding grooves 62 and are fixed in the welding grooves 62 by heat fusion.

[0037] The system employs a mating structure of welding posts 61 and welding grooves 62, fixing the welding posts 61 into the welding grooves 62 via heat fusion. Compared to traditional snap-fit ​​connections, this heat fusion fixing method creates a tight, inseparable whole between the panel 4 and the back cover 5, greatly enhancing the strength and stability of the connection. During use, regardless of the direction of force applied to the display screen, such as vibration, impact, or slight human shaking, there will be no displacement or shaking. Furthermore, there will be no relative movement caused by mutual compression due to shrinkage under high or low temperatures, effectively preventing abnormal noises caused by loose components and providing users with a more stable and quiet user experience.

[0038] Furthermore, the hot-melt connection method of the fusion structure 6 has high reliability and can withstand greater external forces without damage. Unlike snap-fit ​​connections, which may break or loosen due to long-term use or external impact, the connection between the fusion column 61 and the fusion groove 62, after being fused together by heat, has better fatigue resistance and durability, greatly extending the service life of the display screen and reducing maintenance and replacement costs caused by connection problems.

[0039] Please refer to Figure 3 and Figure 5In this embodiment, multiple welding structures 6 are distributed circumferentially between the panel 4 and the back cover 5. The welding structures 6 are distributed at the joint between the panel 4 and the back cover 5, that is, at the position where the panel 4 contacts the back cover 5 when the panel 4 is installed on the back cover 5. Specifically, in this embodiment, the joint between the panel 4 and the back cover 5 has a ring structure, and the multiple welding structures 6 are evenly distributed along the trajectory of this ring structure.

[0040] Multiple fusion structures 6 are distributed circumferentially along the panel 4 and the back cover 5, forming a ring-shaped connection system. This layout can fix the front and rear assemblies from all directions, ensuring the stability of the display screen when subjected to external forces from different directions. Whether it is horizontal shaking, vertical vibration, or oblique impact, each fusion structure 6 can evenly distribute and bear these forces, effectively preventing loosening or damage to the connections due to excessive local stress, and providing comprehensive stability for the display screen.

[0041] Please refer to Figure 2 In this embodiment, the panel 4 and the back cover 5 form a multi-layered stepped structure; each stepped surface has multiple circumferentially spaced welding structures 6 at its joint. Specifically, the panel 4 has a box-like structure with a central cavity. The stepped structure gradually extends outward from the bottom of the cavity, such as a three-tiered structure in this embodiment. Each stepped surface has evenly spaced welding grooves 62, and correspondingly, the back cover 5 also has welding posts 61 corresponding to the welding grooves 62.

[0042] The multi-layered stepped structure provides more contact surfaces and connection points for the connection between panel 4 and back cover 5. Each stepped surface is equipped with a welding structure 6, which is equivalent to building multiple solid connection defenses in both the vertical and horizontal directions of the display screen. This layered connection method makes the connection between panel 4 and back cover 5 tighter and more secure, with each layer supporting and cooperating with each other, greatly enhancing the strength and rigidity of the entire display screen structure.

[0043] Furthermore, the multi-layered stepped structure provides a precise positioning reference for the assembly of panel 4 and back cover 5. Each stepped surface has specific dimensional and shape requirements, allowing operators to quickly and accurately align panel 4 and back cover 5 during assembly, ensuring the positional accuracy of each component. Moreover, the welded structures 6 on each stepped surface collectively form a continuous sealing barrier. Because the welded structures 6 are tightly connected through heat fusion, they effectively prevent dust, moisture, and other impurities from entering the display screen from different layers.

[0044] Please refer to Figure 2It should be noted that, in this embodiment, extension plates 41 are also provided on opposite sides of the panel 4, and the back cover 5 is provided with a support base 51 corresponding to the extension plate 41. Multiple welding structures 6 are provided at the joint between the support plate and the support base 51. The extension plate 41 can serve as an appearance surface and can be flexibly designed according to the actual usage scenario, such as being triangular in this embodiment.

[0045] The extension plate 41 and the support base 51 provide additional support for the lateral structure of the display screen. In traditional display screen structures, the lateral direction is often a weak point, easily deformed or damaged by lateral impacts or pressure. In this embodiment, the extension plate 41 and the support base 51 work together to form a stable lateral support system, effectively dispersing and bearing lateral forces, greatly enhancing the overall impact resistance of the display screen. Furthermore, the multiple welded structures 6 at the junction of the extension plate 41 and the support base 51 provide stable fixing, making the connection between the panel 4 and the back cover 5 more secure in the lateral direction.

[0046] Please refer to Figure 2 and Figure 4 In this embodiment, the panel 4 and the back cover 5 are further fixedly connected by multiple first screws 7. Based on the multi-layered stepped structure, the cooperation between the extension plate 41 and the support base 51, and the connection of the welding structure 6, the additional fixing with multiple first screws 7 further enhances the rigidity of the entire display screen structure. The first screws 7 provide strong axial tensile force, tightly pulling the panel 4 and the back cover 5 together, making them an inseparable whole.

[0047] Please refer to Figure 7 It should be noted that the connection between the welding post 61 and the welding groove 62 in this embodiment is a clearance fit or a transition fit. The use of a clearance fit or transition fit between the welding post 61 and the welding groove 62 greatly simplifies the assembly process. With a clearance fit or transition fit, the welding post 61 can be easily inserted into the welding groove 62, thus providing reasonable assembly convenience.

[0048] Whether it is a clearance fit or a transition fit, once the panel 4 and the back cover 5 can be assembled, one or more sets of hot melt jigs can be used to melt the welding column 61 through the heated welding head on the hot melt jig, so that the welding column 61 fills the gap between it and the welding groove 62. When the welding head leaves and cools naturally, a seamless hot melt weld joint is formed at the hot melt weld joint.

[0049] Please refer to Figure 1In this embodiment, the circuit board 2 and the bracket 3 are respectively fixedly connected to the display module 1 by a plurality of second screws 8. The fixing method of the second screws 8 can accurately position the circuit board 2 and the bracket 3 at the designated positions on the display module 1. In addition, the use of second screws 8 for fixing makes the installation and removal process of the circuit board 2 and the bracket 3 simple and quick.

[0050] In this embodiment, the display module 1 is fixedly connected to the post-assembly body by adhesive 9. The adhesive 9 can be disposed on the edge of the display module 1, and can be a natural adhesive 9, such as starch glue or animal glue; it can also be a synthetic adhesive 9, such as epoxy resin glue, PU glue or polyurethane glue; or it can be an inorganic adhesive 9, such as silicate glue or phosphate glue, etc.

[0051] Adhesive 9 forms a uniform and continuous adhesive layer between the display module 1 and the rear assembly, tightly bonding the two into a single unit. Furthermore, using adhesive 9 for fixation achieves a seamless connection between the display module 1 and the rear assembly, effectively preventing dust, moisture, and other impurities from entering the device and protecting the display module 1 and other electronic components from external environmental corrosion.

[0052] Please refer to Figure 1 In this embodiment, the post-assembly is provided with a plurality of mounting holes 10, through which the bracket 3 communicates with the outside. The mounting holes 10 not only facilitate the installation of the bracket 3 with the external structure, but also provide a convenient channel for the connection of cables inside the equipment, allowing the cables to pass through directly, avoiding the complicated winding process and simplifying the wiring design.

[0053] It should be noted that after the end of the welding post 61 is heat-melted, it forms a mushroom-shaped structure with a diameter larger than the inlet of the welding groove 62, and the mushroom-shaped structure is pressed against the periphery of the welding groove 62.

[0054] After the welding post 61 melts, it forms a mushroom-shaped structure on the welding groove 62. At the same time, the molten part of the welding post 61 fills the gap that mates with the welding groove 62, thus forming a seamless hot-melt weld joint. In addition, the mushroom-shaped structure can be firmly embedded in the material around the welding groove 62 like an anchor, effectively preventing the connection from loosening or separating, and greatly enhancing the connection strength between the two components.
