Description

Technical Field

[0001] This utility model relates to the field of television back cover technology, specifically a thermoformed television back cover. Background Technology

[0002] The back cover of a television, also known as the rear cover or back shell, is part of the television's outer casing. Located at the back of the television casing, it not only protects the television but also helps dissipate heat from internal components and provides connections for interface auxiliary cables. It is usually produced using a vacuum forming process.

[0003] Traditional TV back covers require connectors to plug into interfaces on the back cover during use. These connections need to maintain a certain level of stability to ensure stable cable delivery. Therefore, we propose a vacuum-formed TV back cover to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a thermoformed television back cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thermoformed television back cover, comprising a back cover body, a heat dissipation hole installed at the top of the front end of the back cover body, a mounting base provided at the front end of each heat dissipation hole, a dustproof mesh movably disposed inside the mounting base, and a pushing block installed at the top of each dustproof mesh, and a wire interface provided at the bottom right side of the back cover body.

[0006] Preferably, the cross-section of the mounting base is larger than the cross-section of the dustproof mesh, and the mounting base and the dustproof mesh form an interlocking structure.

[0007] Preferably, a protective seat is provided on the outer side wall of the line interface, and one side of the protective seat is fixed to the outer side wall of the rear cover body. Threaded rods are movably provided at both the upper and lower ends of the protective seat. A rotating block is installed at one end of each threaded rod, and a locking block is installed at the other end of each threaded rod. Sliding seats are movably provided on both sides inside the locking block, and one side of each sliding seat is fixed to the inner side wall of the protective seat.

[0008] Preferably, the cross-section of the locking block is larger than the cross-section of the sliding seat, and the locking block and the sliding seat form a sliding structure.

[0009] Preferably, there are several locking blocks, and the several locking blocks are symmetrically distributed about the central axis of the line interface.

[0010] Preferably, the upper and lower ends of the protective seat are evenly provided with internal threads, and the protective seat and the threaded rod form a threaded connection.

[0011] Preferably, a reinforcing frame is installed at the front end of the rear cover body via a fastener, and an oblique reinforcing rod is installed inside the reinforcing frame.

[0012] Preferably, the reinforcing frames are distributed in a crisscross pattern, and the reinforcing frames and the diagonal reinforcing rods are welded together to form a whole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the vacuum-formed TV back cover not only enables the interface at the interface to be limited and reinforced, and achieves dust protection for the heat dissipation holes, but also greatly increases the structural strength of the back cover body.

[0014] (1) When the back cover body is in use, the external cable connector is connected to the TV by inserting it into the cable interface. At this time, the connector inserted into the cable interface can be limited by the components such as sliding seat, rotating block, locking block and threaded rod, so that the connector is stably connected to the TV through the back cover body and is not easy to loosen or fall off during use, making the TV more stable to use.

[0015] (2) When the back cover is in use, the heat of the internal components of the TV is discharged through the heat dissipation holes to dissipate heat. By setting a dustproof mesh at the rear end of the heat dissipation holes, the heat dissipation holes can be protected to prevent external dust from entering the TV through the heat dissipation holes. The dustproof mesh can also be disassembled and cleaned later, thus realizing the dust protection of the heat dissipation holes by the back cover.

[0016] (3) By setting up components such as diagonal reinforcing rods, fasteners and reinforcing frames at the front end inside the back cover body, the diagonal reinforcing rods and reinforcing frames are welded together to form a whole and fixed to the front end inside the back cover body by fasteners, the structural strength of the back cover body is greatly increased, and it is not easy to deform and be damaged during use, thus extending the service life of the back cover body.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides an embodiment: a vacuum-formed TV back cover, including a back cover body 1, a heat dissipation hole 11 installed at the top of the front end of the back cover body 1, a mounting base 3 provided at the front end of each heat dissipation hole 11, a dustproof mesh 2 movably installed inside the mounting base 3, and a pushing block 4 installed at the top of each dustproof mesh 2, a wire interface 6 provided at the bottom right side of the back cover body 1, the cross-section of the mounting base 3 is larger than the cross-section of the dustproof mesh 2, and the mounting base 3 and the dustproof mesh 2 form a snap-fit ​​structure. The snap-fit ​​structure design facilitates the disassembly and cleaning of the dustproof mesh 2;

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the external cable connector is inserted into the cable interface 6 and connected to the television through the back cover body 1. After connection, the rotating blocks 8 at the upper and lower ends of the protective seat 5 are rotated in sequence. The rotation of the rotating blocks 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 pushes the locking block 9 to fit against the outer wall of the cable connector inserted into the cable interface 6 through the sliding of the locking block 9 on the outer wall of the sliding seat 7, so that the cable connector is stably and firmly inserted into the cable interface 6 for use.

[0025] A protective seat 5 is provided on the outer wall of the cable interface 6, and one side of the protective seat 5 is fixed to the outer wall of the rear cover body 1. Threaded rods 10 are movably provided at both the upper and lower ends of the protective seat 5. A rotating block 8 is installed at one end of each threaded rod 10, and a locking block 9 is installed at the other end of each threaded rod 10. Sliding seats 7 are movably provided on both sides inside the locking block 9, and one side of each sliding seat 7 is fixed to the inner side wall of the protective seat 5. The cross-section of the locking block 9 is larger than the cross-section of the sliding seat 7. A sliding structure is formed between the locking block 9 and the sliding seat 7. Several locking blocks 9 are provided, and the several locking blocks 9 are symmetrically distributed about the central axis of the cable interface 6. Internal threads are evenly provided at both the upper and lower ends inside the protective seat 5. A threaded connection is formed between the protective seat 5 and the threaded rod 10, so that the locking block 9 can move stably to one side to limit and lock the connector plug.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, when the back cover body 1 is installed at the rear of the TV, the heat generated inside the TV is dissipated through the heat dissipation hole 11. The dustproof mesh 2 protects the rear of the heat dissipation hole 11 to prevent dust from entering the TV through the heat dissipation hole 11. Subsequently, by pressing the push block 4, the dustproof mesh 2 can be pushed upward from the inside of the mounting base 3, so that the dustproof mesh 2 can be moved out from the inside of the mounting base 3 and removed. After cleaning and maintenance, the dustproof mesh 2 can be reinstalled in its original position for continued dust protection.

[0027] A reinforcing frame 14 is installed at the front end of the back cover body 1 via a fastener 13. An oblique reinforcing rod 12 is installed inside the reinforcing frame 14. The reinforcing frames 14 are distributed in a crisscross manner. The reinforcing frames 14 and the oblique reinforcing rods 12 are welded together to form an integral whole, which provides better reinforcement for the back cover body 1.

[0028] Specifically, such as Figure 4 As shown, the diagonal reinforcing rod 12 and the reinforcing frame 14 form a whole and are installed inside the back cover body 1 by the fastener 13, which improves the structural strength of the back cover body 1 and makes the back cover body 1 less prone to deformation and damage.

[0029] Working principle: When using this utility model, the main body 1 of the back cover is taken out and installed on the rear end of the TV. The external connector of the TV is inserted into the inside of the cable interface 6 and connected to the TV. After the connector is inserted into the inside of the cable interface 6, the rotating blocks 8 at the upper and lower ends of the protective seat 5 are rotated in sequence. The rotation of the rotating blocks 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 pushes the locking block 9 to fit against the outer wall of the cable connector inserted into the cable interface 6 through the sliding of the locking block 9 on the outer wall of the sliding seat 7, thus limiting the connection of the connector. When the TV is in use, the heat generated by its internal components is discharged through the heat dissipation holes 11 on both sides. When the heat is discharged through the heat dissipation holes 11, the dustproof mesh 2 protects the front end of the heat dissipation holes 11 for dust protection.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
