Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a back cover and a television. Background Technology

[0002] The back cover of most current televisions adopts a split structure design, mainly composed of a back shell and a back panel. The back shell, as the main supporting structure, is usually made of high-strength engineering plastics or metal; the back panel, as a supplementary reinforcement, together with the back shell forms the rigid frame of the television. It not only provides stable mechanical support for the whole set, but also effectively protects the internal core board, power board, display driver board and other precision electronic components from damage caused by physical impact, squeezing or dropping.

[0003] Currently, the back cover and back panel typically use a snap-fit ​​design. While this design improves assembly efficiency, the excessively large clearance required for assembly processes results in noticeable light transmission defects at the back panel clearance. In a dark environment, these defects can cause visible halos around the screen, severely impacting the user's visual experience. Utility Model Content

[0004] The purpose of this utility model is to provide a back cover and a television, with an integral back cover having a light-shielding barrier that completely surrounds the clearance gap, thus solving the halo phenomenon caused by the back panel gap in existing televisions.

[0005] To achieve the above objectives, this utility model provides a back cover, including a back plate and a back shell disposed opposite to each other; the back plate is provided with a slot on the side facing the back shell, and the back shell is provided with a buckle that engages with the slot; one side of the slot is provided with a clearance notch for avoiding the buckle.

[0006] The rear shell has an integral light-shielding barrier on the side facing the back panel. The light-shielding barrier is placed over the clearance opening and abuts against the back panel. The light-shielding barrier is used to prevent light from leaking through the clearance opening.

[0007] In some embodiments, the rear shell includes a heat dissipation side plate perpendicular to the back panel. The heat dissipation side plate has a heat dissipation area and a shielding area. The heat dissipation area has a plurality of heat dissipation through holes. The shielding area and the light-shielding enclosure form an enclosing cavity, which surrounds the upper part of the avoidance gap.

[0008] In some embodiments, the shading enclosure includes a cover plate that covers the clearance opening; the heat dissipation area is positioned above the cover plate.

[0009] In some embodiments, a raised ridge is formed at the connection between the heat dissipation area and the shielding area; the shielding baffle is integrally and vertically fixed to the raised ridge; or, the shielding baffle is integrally and vertically fixed to the shielding area.

[0010] In some embodiments, the rear shell further includes a top cover plate integrally and vertically connected to the heat dissipation side plate, the top cover plate being parallel to and opposite to the back plate; the light-shielding enclosure further includes a left side baffle and a right side baffle integrally fixed between the top cover plate and the heat dissipation side plate, the light-shielding baffle being integrally and vertically fixed between the left side baffle and the right side baffle.

[0011] In some embodiments, the shading enclosure further includes a front baffle integrally and vertically fixed between the left baffle, the right baffle and the covering baffle; the front baffle is parallel to and opposite to the heat dissipation side plate, and the front baffle is provided with a demolding notch.

[0012] In some embodiments, a reinforcing rib is integrally fixed between the top cover and the heat dissipation side plate.

[0013] In some embodiments, the heat dissipation area has a reinforcing rib formed on the side away from the shading enclosure, and the reinforcing rib and heat dissipation through holes are alternately distributed.

[0015] This utility model also provides a television, including the aforementioned back cover.

[0016] Compared to the prior art, this utility model optimizes the structure of the back cover. The optimized back cover includes a back plate and a back shell arranged opposite each other. The back plate has a slot on the side facing the back shell, and the back shell has a buckle. The buckle engages with the slot to fix the back shell to the back plate. An avoidance notch is provided on one side of the slot to avoid the buckle, preventing assembly interference between the buckle and the back plate and ensuring smooth assembly of the back shell and the back plate.

[0017] A light-shielding barrier is integrated on the side of the back cover facing the back panel.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model discloses a back cover, including a back plate 1 and a back shell 2 disposed opposite to each other. The back plate 1 has a slot 11 on the side facing the back shell 2, and the back shell 2 has a buckle 21. The buckle 21 engages with the slot 11, fixing the back shell 2 onto the back plate 1. In other words, the buckle 21 design between the back plate 1 and the back shell 2 in this utility model facilitates disassembly and assembly, improving the assembly efficiency of the back cover.

[0033] One side of the slot 11 is provided with a clearance notch 12 to avoid the buckle 21, thereby preventing assembly interference between the buckle 21 and the back plate 1 and ensuring smooth assembly of the back cover 2 and the back plate 1. Specifically, the clearance notch 12 is a rectangular through hole that extends along the thickness direction of the back plate 1.

[0034] The rear shell 2 has an integrally provided light-shielding enclosure 22 on the side facing the back panel 1, as shown in the attached image. Figure 1 As shown, the light-shielding barrier 22 is located at the clearance notch 12 and abuts against the back panel 1, so that the light-shielding barrier 22 forms a three-dimensional surrounding structure that completely covers the clearance notch 12, preventing light leakage from the clearance notch 12; moreover, the one-piece design of the light-shielding barrier 22 can avoid assembly gaps, eliminate the risk of secondary light leakage, and enable the light-shielding barrier 22 to effectively solve the halo phenomenon caused by the notch in the back panel 1 of existing TVs, making the screen display boundary clearer and improving the user's visual experience.

[0035] In a preferred embodiment, the rear cover 2 includes a heat dissipation side plate 23 perpendicular to the back plate 1, which serves both support and heat dissipation functions. A buffer sealing strip can be provided between the heat dissipation side plate 23 and the back plate 1 to ensure a tight fit and also provide shock absorption and dust prevention. Specifically, the heat dissipation side plate 23 has a heat dissipation area 231 and a shielding area 232. The heat dissipation area 231 has several heat dissipation holes 2311, through which hot air flowing from between the rear cover 2 and the back plate 1 exchanges heat with the cold air outside, enabling the entire rear cover to dissipate heat. The shielding area 232 and the light-shielding barrier 22 form an enclosure cavity 26, which surrounds the clearance notch 12, ensuring that the enclosure cavity 26 completely surrounds the clearance notch 12. Since the heat dissipation area 231 has a lot of heat dissipation holes 2311, in order to prevent the mechanical strength of the heat dissipation area 231 from being too low, the thickness of the heat dissipation area 231 is greater than the thickness of the shielding area 232, so as to ensure that the heat dissipation side plate 23 has sufficient strength.

[0036] The light-blocking enclosure 22 includes a cover plate 221 covering the clearance opening 12. The cover plate 221 is parallel to the back plate 1. The heat dissipation area 231 is set higher than the cover plate 221 to prevent the heat dissipation hole 2311 from transmitting light.

[0037] A raised ridge 233 is formed at the connection between the heat dissipation area 231 and the shielding area 232. The shielding baffle 221 is integrally and vertically fixed to the raised ridge 233, so that the light-shielding enclosure 22 is completely located below the heat dissipation area 231. This not only prevents light from passing through the heat dissipation hole 2311, but also facilitates integral molding processing. Alternatively, the cover baffle can be integrally and vertically fixed to the shielding area 232, which also ensures that the light-shielding enclosure 22 is completely located below the heat dissipation area 231.

[0038] The rear cover 2 also includes a top cover 24 that is integrally and vertically connected to the heat dissipation side plate 23. The top cover 24 is parallel to the back plate 1. The cover baffle 221 is located between the top cover 24 and the back plate 1, so that a heat dissipation cavity is formed between the cover baffle 221 and the top cover 24. The heat dissipation cavity is connected to several heat dissipation through holes 2311, ensuring that the cover does not affect the normal heat dissipation of the rear cover while enclosing the clearance gap 12.

[0039] The shading enclosure 22 also includes a left baffle 222 and a right baffle 223 integrally fixed between the top cover plate 24 and the heat dissipation side plate 23, with the left baffle 222 and the right baffle 223 being parallel to each other. The covering baffle 221 is integrally and vertically fixed between the left baffle 222 and the right baffle 223, forming a U-shaped shading cavity that completely covers the avoidance gap 12. This closed frame structure allows for a more uniform distribution of mechanical stress on the shading enclosure 22.

[0040] The light-shielding enclosure 22 also includes a front baffle 224 that is integrally and vertically fixed between the left baffle 222, the right baffle 223, and the cover baffle 221. The front baffle 224 is parallel to and opposite the heat dissipation side plate 23, and the front baffle 224 is provided with a demolding notch 2241 for easy demolding. In other words, the left baffle 222, the right baffle 223, the front baffle 224, and the cover baffle 221 are designed as a single unit, effectively eliminating traditional seams, avoiding light diffraction at the seams, and ensuring that there is no halo phenomenon at the edge of the screen.

[0041] In a preferred embodiment, a reinforcing rib 25 is integrally fixed between the top cover 24 and the heat dissipation side plate 23 to improve the mechanical strength between the top cover 24 and the heat dissipation side plate 23, thereby improving the bending strength of the rear shell 2. Specifically, the reinforcing rib 25 can be a triangular rib to form a triangular support structure.

[0042] In a preferred embodiment, the heat dissipation area 231 has a reinforcing rib 2312 formed on the side away from the light-shielding enclosure 22. The reinforcing rib 2312 and the heat dissipation through holes 2311 are alternately distributed, which can not only ensure the normal heat dissipation of the heat dissipation area 231, but also improve the bending strength of the heat dissipation area 2311. Specifically, all the heat dissipation through holes 2311 are evenly distributed in rows, and a reinforcing rib 2312 protrudes between any two adjacent rows of heat dissipation through holes 2311.

[0043] As a preferred embodiment, as shown in the appendix Figure 2As shown, the back panel 1 has a protrusion 13 on the side facing the rear shell 2, and a light-shielding barrier 22 covers the outer periphery of the protrusion 13. The slot 11 is a stepped slot 11 on one side of the protrusion 13. The buckle 21 has an elastic hook that cooperates with the stepped slot 11. The elastic hook is pressed and fixed in the stepped slot 11, so that the elastic hook is fixed to the stepped slot 11 by elastic force, which facilitates disassembly and assembly. The end of the elastic hook is bent to form a limiting flange 211. The limiting flange 211 abuts against the groove edge of the stepped slot 11, limiting the position of the elastic hook in the stepped slot 11, reducing the risk of the elastic hook detaching from the stepped slot 11, and improving the connection reliability between the buckle 21 and the slot 11.

[0044] This utility model also provides a television, including the aforementioned back cover, which has the same beneficial effects.
