Description

Technical Field

[0001] This invention relates to the field of television technology, and more specifically to a television back panel structure that is easy to assemble and a smart television. Background Technology

[0002] The back panel of existing smart TVs usually adopts an integral structure and is fixed to the frame of the TV with multiple screws. The back panel lacks clear guidance and limiting structure during installation, and requires repeated alignment and adjustment during assembly, resulting in low assembly efficiency.

[0003] Meanwhile, under the aforementioned overall fixed structure, the back panel forms a closed state after installation. When it is necessary to inspect or replace the back functional components, the entire back panel must often be disassembled. This not only involves cumbersome disassembly and assembly steps, but also easily causes wear on the connecting parts during repeated disassembly and assembly, affecting the structural stability and reliability of the entire machine. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a TV back panel structure and a smart TV that are easy to assemble.

[0005] To achieve the above objectives, the specific solution of the present invention is as follows:

[0006] The first aspect of the present invention provides a television back panel structure that is easy to assemble, including a back panel body; the top of the back panel body is provided with an installation notch; a flip cover is hinged in the installation notch;

[0007] The back panel body has multiple mounting protrusions arranged along its width on both sides at intervals; a first slot is formed between adjacent mounting protrusions; a fixing block is provided above the uppermost mounting protrusion on the back panel body; the fixing block is movably equipped with a locking pin.

[0008] The back panel body has push bars slidably provided on both sides of the mounting notch; one end of the push bar is provided with a drive arm for driving the movement of the locking pin; the other end of the push bar is provided with a sliding pin; the two sides of the flip cover are provided with first locking holes for engaging with the sliding pin.

[0009] In some embodiments, both side walls of the back plate body are provided with extrusion bosses above the uppermost mounting boss; a second slot is formed between the extrusion boss and the corresponding uppermost mounting boss; the fixing block is disposed in the second slot.

[0010] In some embodiments, the fixing block is provided with a first U-shaped opening for cooperating with the drive arm; a sliding hole is provided on one side of the first U-shaped opening; the locking pin is movably disposed in the sliding hole; a first tension spring is connected to the middle of the locking pin and the other side of the first U-shaped opening; the first tension spring causes the locking pin to be received in the sliding hole;

[0011] The drive arm has a clearance notch in the middle for avoiding the first tension spring; when the drive arm is inserted into the first U-shaped opening, the drive arm squeezes the locking pin and causes the locking pin to overcome the elastic force of the first tension spring and protrude out of the sliding hole.

[0012] In some embodiments, the other end of the push bar is provided with a second U-shaped opening; the sliding pin includes a T-shaped portion and a locking head for engaging with the first locking hole; the T-shaped portion is slidably disposed within the second U-shaped opening; the locking head is fixedly disposed at one end of the horizontal arm of the T-shaped portion near the flip cover and located outside the second U-shaped opening; a first spring is sleeved on the vertical arm of the T-shaped portion; the two ends of the first spring abut against the push bar and the horizontal arm of the T-shaped portion, respectively.

[0013] In some embodiments, both sides of the flip cover are provided with drive ramps for contacting and engaging with the card head.

[0014] In some embodiments, a second spring is connected between the push bar and the back plate body.

[0015] In some embodiments, the back plate body is provided with limiting grooves at the top corners on both sides of the mounting notch; the push bar is located in the limiting grooves.

[0016] In some embodiments, a protrusion is provided in the center of the top of the flip cover.

[0017] A second aspect of the present invention provides a smart television, including an LCD screen and a television back panel structure as described above;

[0018] The LCD screen has mounting platforms on both sides; the mounting platforms are provided with mounting grooves for sliding cooperation with mounting bosses; the mounting platforms are also slidably provided with mounting strips whose sliding direction is perpendicular to the mounting direction of the back panel body.

[0019] The top of the mounting strip is provided with a second locking hole for engaging with a locking pin; the mounting strip is provided with a plurality of wedge-shaped locking platforms arranged at intervals along its length; the wedge-shaped locking platforms can be embedded in the first locking groove.

[0020] In some embodiments, a second tension spring is connected between the mounting strip and the mounting platform;

[0021] The top of the mounting strip is provided with a third U-shaped opening for engaging with the fixing block; the second locking hole is located on one side of the third U-shaped opening; after the locking pin protrudes out of the sliding hole, it protrudes into the second locking hole, thereby locking the mounting strip.

[0022] The beneficial effects of this invention are as follows: By setting an installation slide and a corresponding locking structure (installation boss, first locking groove, and wedge-shaped boss), the back panel body can be quickly assembled and reliably locked in a predetermined direction, reducing alignment adjustments during assembly and improving assembly efficiency. Furthermore, by linking the snap-fit ​​of the flip cover with the locking of the mounting strip, the flip cover automatically locks and fixes the mounting strip after installation, reliably fixing the back panel body to the back of the LCD screen. When maintenance is required, the flip cover can be opened (simultaneously releasing the locking of the mounting strip), allowing for partial maintenance without completely disassembling the back panel body. When disassembly is required, the back panel body can be pulled out by prying the mounting strip outwards. This design improves the stability of the back panel structure and the overall ease of maintenance. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the invention to this.

[0039] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0040] It should also be noted that the directional terms such as left, right, up, and down in this embodiment are only relative concepts or are based on the normal use of the product, and should not be considered as restrictive.

[0041] like Figures 1 to 14 As shown in the figure, the smart TV that is easy to assemble according to this embodiment includes an LCD screen 1 and a TV back panel structure assembled on the back of the LCD screen 1.

[0042] The back panel structure of the television includes a back panel body 21; a mounting notch 211 is recessed at the top of the back panel body 21; a flip cover 22 is provided in the mounting notch 211; the middle of the bottom end of the flip cover 22 is hinged to the back panel body 21, so that the flip cover 22 can swing with its hinge point as the fulcrum; multiple mounting bosses 212 are provided at intervals along the width direction on both sides of the back panel body 21; a first slot 213 is formed between adjacent mounting bosses 212; the back panel body 21 has a mounting boss 212 above the uppermost mounting boss 212. There is a fixing block 23; the fixing block 23 is movably provided with a locking pin 232; the back plate body 21 is slidably provided with push bars 24 on both sides of the mounting notch 211; one end of the push bar 24 is provided with a drive arm 241 for driving the movement of the locking pin 232; the other end of the push bar 24 is movably provided with a sliding pin 242; the two sides of the flip cover 22 are provided with first locking holes 221 for engaging with the sliding pin 242, so that the free end of the flip cover 22 is engaged with the back plate body 21 through the first locking holes 221 engaging with the sliding pin 242.

[0043] The LCD screen 1 has mounting platforms 11 on both sides of its back; the mounting platforms 11 are provided with mounting grooves 12 for sliding engagement with mounting bosses 212. During installation, the back panel body 21 is lifted from bottom to top, so that the mounting bosses 212 on both sides slide into the mounting grooves 12 in sequence; the mounting platforms 11 are also slidably provided with mounting strips 13 whose sliding direction is perpendicular to the installation direction of the back panel body 21.

[0044] The top of the mounting strip 13 is provided with a second locking hole 133 for engaging with the locking pin 232, thus achieving the locking between the back panel body 21 and the LCD screen 1; the mounting strip 13 is provided with a plurality of wedge-shaped locking platforms 131 arranged at intervals along its length; the wedge-shaped locking platforms 131 can be embedded into the corresponding first locking slots 213, thus locking and limiting the back panel body 21 and providing support for the back panel body 21.

[0045] Specifically, in this embodiment of the easy-to-assemble smart TV, the flip cover 22 is in the open state during assembly, and the back panel body 21 is lifted from bottom to top, causing the mounting protrusions 212 to slide into the mounting grooves 12. During the sliding process, the mounting protrusions 212 press against the wedge-shaped retaining platforms 131 on the mounting strips 13 until the back panel body 21 is lifted into place. Each wedge-shaped retaining platform 131 then corresponds to a first retaining slot 213, and each wedge-shaped retaining platform 131 is then embedded into its corresponding first retaining slot 213. Figure 2 and Figure 3As shown, the back panel body 21 is locked in place. Then, the flip cover 22 is closed in the mounting notch 211. During the closing process, the flip cover 22 compresses the sliding pin 242 to retract and pushes the push bar 24 to slide. During the sliding of the push bar 24, the drive arm 241 compresses the locking pin 232 on the fixing block 23, so that the locking pin 232 protrudes into the second locking hole 133 to lock the mounting strip 13. When the sliding pin 242 corresponds to the position of the first locking hole 221, the sliding pin 242 and the first locking hole 221 engage in a latching engagement, thereby locking the flip cover 22. At the same time, the flip cover 22 continues to compress the push bar 24, so that the drive arm 241 continues to compress the locking pin 232, thereby maintaining the locking of the mounting strip 13 and keeping the wedge-shaped boss embedded in the first locking groove 213. Thus, the installation of the back panel body 21 is completed.

[0046] When partial maintenance is required, the flip cover 22 can be pried open to release the sliding pin 242 from the first locking hole 221, thereby unlocking the flip cover 22. Then, the flip cover 22 can be opened outward to release the pressure on the push bar 24. The push bar 24 resets and releases the pressure on the locking pin 232. The locking pin 232 exits from the second locking hole 133, thereby releasing the lock on the mounting strip 13. At this time, partial maintenance can be performed by opening the flip cover 22. If the entire back panel body 21 needs to be disassembled, the mounting strips 13 on both sides can be pried outward to release the wedge-shaped protrusion from the first locking groove 213. At this time, the back panel body 21 can be pulled downward to achieve the overall disassembly of the back panel body 21.

[0047] This embodiment, by setting up the mounting slide 12 and its cooperating locking structure (mounting boss 212, first locking groove 213, and wedge-shaped boss), enables the back panel body 21 to be quickly assembled and reliably locked in a predetermined direction, reducing alignment adjustments during assembly and improving assembly efficiency. Furthermore, by linking the snap-fit ​​of the flip cover 22 with the locking of the mounting strip 13, the flip cover 22 automatically locks and fixes the mounting strip 13 after being installed in place, reliably fixing the back panel body 21 to the back of the LCD screen 1. When maintenance is required, the flip cover 22 can be opened (simultaneously releasing the locking of the mounting strip 13), allowing for partial maintenance without completely disassembling the back panel body 21. When disassembly of the back panel body 21 is required, the mounting strip 13 can be pulled outwards. This design improves the stability of the back panel structure and the overall ease of maintenance.

[0048] In this embodiment, a smart TV that is easy to assemble, such as Figure 2 , Figures 4 to 7As shown, both sides of the backplate body 21 have pressing bosses 214 above the uppermost mounting bosses 212; a second slot 215 is formed between the pressing bosses 214 and the corresponding uppermost mounting bosses 212; a fixing block 23 is disposed in the second slot 215. Specifically, in this embodiment, by setting the pressing bosses 214, it is convenient for the pressing bosses 214 and the wedge-shaped bosses to engage during the installation of the backplate body 21, thereby making the process of pushing the backplate body 21 into the mounting groove 12 smoother.

[0049] Preferably, such as Figure 2 and Figure 13 As shown, a limiting plate 132 is provided at the top of the mounting strip 13; a second locking hole 133 is provided on the limiting plate 132; thus, after the back panel body 21 is pushed into place, the limiting plate 132 corresponds to the position of the second locking groove 215, and the mounting strip 13 drives the limiting plate 132 to embed into the second locking groove 215, so that the position of the second locking hole 133 corresponds to the position of the locking pin 232. Therefore, when the flip cover 22 is closed, the drive arm 241 presses the locking pin 232 into the second locking hole 133, thereby locking the mounting strip 13.

[0050] In this embodiment, a smart TV that is easy to assemble, such as Figure 10 , Figure 11 , Figure 13 and Figure 14 As shown, the fixing block 23 is provided with a first U-shaped opening 231 for cooperating with the drive arm 241; the thickness of the drive arm 241 is adapted to the opening width of the first U-shaped opening 231 so that the drive arm 241 can be reliably embedded in the first U-shaped opening 231, and a sliding hole is provided on one side of the first U-shaped opening 231; a locking pin 232 is movably disposed in the sliding hole; a first tension spring 233 is connected to the middle part of the locking pin 232 and the other side of the first U-shaped opening 231; the first tension spring 233 causes the locking pin 232 to be received in the sliding hole; the middle part of the drive arm 241 is provided with a clearance notch 2411 for avoiding the first tension spring 233; when the drive arm 241 is inserted into the first U-shaped opening 231, the drive arm 241 squeezes the locking pin 232 and causes the locking pin 232 to protrude out of the sliding hole against the elastic force of the first tension spring 233.

[0051] Specifically, when the flip cover 22 is closed, the flip cover 22 presses the push bar 24 to slide, and the push bar 24 drives the drive arm 241 to embed into the first U-shaped opening 231. The first tension spring 233 is located in the clearance notch 2411. At this time, the drive arm 241 presses the locking pin 232 to overcome the elastic force of the first tension spring 233, protrudes out of the sliding hole, and embeds into the second locking hole 133, thereby simultaneously locking and fixing the mounting strip 13. In this way, the locking operation of the flip cover 22 and the locking operation of the mounting strip 13 are linked, making the installation more convenient.

[0052] When the flip cover 22 is opened, the flip cover 22 releases the pressure on the push bar 24, the push bar 24 drives the drive arm 241 to reset, the drive arm 241 releases the pressure on the locking pin 232, at this time the locking pin 232 is removed from the second locking hole 133 under the action of the return elastic force of the tension spring and is received in the sliding hole, thereby releasing the locking of the mounting strip 13.

[0053] like Figure 11 and Figure 12 As shown, in this embodiment of the easily assembled smart TV, the other end of the push bar 24 is provided with a second U-shaped opening 243; the sliding pin 242 includes a T-shaped portion 2421 and a locking head 2422 for engaging with the first locking hole 221; the T-shaped portion 2421 is slidably disposed within the second U-shaped opening 243; the locking head 2422 is fixedly disposed at one end of the horizontal arm of the T-shaped portion 2421 near the flip cover 22 and located outside the second U-shaped opening 243; preferably, both the front and rear sides of the locking head 2422 are provided with arc surfaces; a first spring 2423 is sleeved on the longitudinal arm of the T-shaped portion 2421; the two ends of the first spring 2423 respectively abut against the push bar 24 and the horizontal arm of the T-shaped portion 2421 to provide a restoring elastic force for the sliding pin 242. Figure 6 and Figure 8 As shown, in this embodiment of the easily assembled smart TV, both sides of the flip cover 22 are provided with driving inclined surfaces 222 for contacting and engaging with the clip head 2422. Figure 6 and Figure 7 As shown, in the easily assembled smart TV of this embodiment, a second spring 25 is connected between the push bar 24 and the back panel body 21. The second spring 25 provides a reset force for the push bar 24. The stiffness of the second spring 25 is greater than that of the first spring 2423, so as to realize the orderly movement of the sliding pin 242 and the push bar 24.

[0054] Specifically, when the flip cover 22 is not closed, the latch 2422 is in a protruding state under the elastic force of the first spring 2423; when the flip cover 22 is closed, the driving inclined surfaces 222 on both sides of the flip cover 22 contact the latch 2422 of the corresponding sliding pin 242 and squeeze the latch 2422, causing the first spring 2423 to be compressed, and the T-shaped part 2421 to retract inward to the second U-shaped opening 243 until the sliding pin 242 is retracted into place. Then, the flip cover 22 continues to squeeze the latch 2422 through the driving inclined surfaces 222, thereby generating a pushing force on the push bar 24, so that the push bar 24 relative to the back plate... As body 21 slides, the second spring 25 is compressed until the push bar 24 slides into place. Then, the driving inclined surface 222 disengages from the locking head 2422. At this time, the locking head 2422 contacts the vertical side of the flip cover 22. When the position of the first locking hole 221 corresponds to the position of the locking head 2422, the locking head 2422 is inserted into the first locking hole 221 under the elastic force of the first spring 2423, thereby realizing the locking of the flip cover 22. At the same time, the end face of the push bar 24 remains in contact with the vertical side of the flip cover 22, thereby continuously pressing the push bar 24 to keep the mounting strip 13 in the locked state.

[0055] When the flip cover 22 is opened, the flip cover 22 is pried outward, causing the latch 2422 to exit from the first latch hole 221. The flip cover 22 gradually releases the pressure on the push bar 24. The first spring 2423 pushes the sliding pin 242 to reset, and the second spring 25 pushes the push bar 24 to reset, thereby releasing the pressure on the latch pin 232 by the drive arm 241, and thus simultaneously releasing the lock on the mounting bar 13.

[0056] In this embodiment, a smart TV that is easy to assemble, such as Figure 6 and Figure 7 As shown, the backplate body 21 has limiting grooves 216 at the top corners on both sides of the mounting notch 211; the push bar 24 is located within the limiting grooves 216; the limiting grooves 216 are smoothly connected to the second slot 215. In this embodiment, by setting the limiting grooves 216, the push bar 24 is provided with limiting and guiding functions, making the movement of the push bar 24 more stable, so as to ensure reliable cooperation between the drive arm 241 and the locking pin 232. Specifically, the limiting grooves 216 are approximately Z-shaped, and the push bar 24 is also approximately Z-shaped.

[0057] In this embodiment, a smart TV that is easy to assemble, such as Figure 1 , Figure 4 as well as Figure 6 As shown, a protrusion 223 is provided in the center of the top of the flip cover 22. In this embodiment, the protrusion 223 is provided to facilitate the operation of the flip cover 22 by the installer.

[0058] In this embodiment, a smart TV that is easy to assemble, such as Figure 2 and Figure 3As shown, a second tension spring 14 is connected between the mounting strip 13 and the mounting platform 11 to provide a reset elastic force for the mounting strip 13; the limiting plate 132 is provided with a third U-shaped opening 134 for cooperating with the fixing block 23. The opening width of the third U-shaped opening 134 is adapted to the thickness of the corresponding end of the fixing block 23 so that the fixing block 23 can be embedded in the third U-shaped opening 134; the second locking hole 133 is provided on one side of the third U-shaped opening 134; after the locking pin 232 protrudes out of the sliding hole, it protrudes into the second locking hole 133, thereby locking the mounting strip 13.

[0059] Specifically, when the back plate body 21 is pushed into the mounting groove 12, the mounting strip 13 is compressed by the cooperation of the pressing boss 214 and the wedge boss, and the mounting boss 212 and the wedge boss. This causes the second tension spring 14 to be stretched until the back plate body 21 is pushed into place. Each wedge-shaped locking platform 131 corresponds to each first locking groove 213. The mounting strip 13 is reset under the action of the second tension spring 14, so that each wedge-shaped locking platform 131 is embedded in the corresponding first locking groove 213. The fixing block 23 is embedded in the third U-shaped opening 134, so that the second locking hole 133 corresponds to the locking pin 232. Thus, when the drive arm 241 presses the locking pin 232 to overcome the elastic movement of the first tension spring 233, the locking pin 232 can protrude into the second locking hole 133 to lock and fix the mounting strip 13.

[0060] In this embodiment, a smart TV that is easy to assemble, such as Figure 1 and Figure 14 As shown, in order to make the operation more convenient when disassembling the entire back panel body 21, a push arm 135 is provided on the mounting strip 13; thus, the maintenance personnel can push the mounting strip 13 to overcome the elastic force of the second tension spring 14 by holding the push arm 135, so as to release the locking limit of the back panel body 21.

[0061] The smart TV in this embodiment, which is easy to assemble, is suitable for practical applications, such as... Figure 1 As shown, a base bracket 3 is fixedly connected to the bottom of the backplate body 21, providing support for stable placement on an external support surface.

[0062] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included within the protection scope of this patent application.
