DETAILED DESCRIPTION

[0066] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0067] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0068] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0069] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0070] At present, in order to facilitate the lifting and installation of super-large TVs, most of the auxiliary tools such as handles are installed on the rear shell of the TV, but most of the handles are directly installed on the rear shell and exposed on the back of the TV, which destroys the integrity of the overall appearance of the TV and reduces the user experience. To solve this problem, this application proposes a display device and takes a TV as an example for explanation.

[0071] For ease of description and understanding, the state of the display device when placed upright for use is used as a reference, the vertical direction is the up and down direction, the direction facing the user is the front, the direction facing away from the user is the rear, and the width direction of the display device is the left and right direction.

[0072] Figure 1 A schematic structural diagram of the back side of a display device according to some embodiments is shown. Figure 2 A schematic structural diagram of a carrying handle in a display device according to some embodiments when the carrying handle is in a first installation state is shown. Figure 3 Shows Figure 2 A partial enlarged view of point A in the middle.

[0073] See also Figures 1 to 3 This embodiment provides a display device. The display device may include a display panel (not shown in the figure), and the display panel is used to display images for users to watch. The display panel may be a liquid crystal display panel.

[0074] In some embodiments, the display device may include a light source (not shown in the figure) and an optical film (not shown in the figure). The light source, the optical film and the display panel are arranged in sequence from the back to the front. The light emitted by the light source passes through the optical film and is projected onto the display panel. After passing through the display panel, the image information is displayed on the display panel. The display panel is located in front of the optical film, and the light in the optical film is transmitted forward to the display panel. The liquid crystal molecules in the display panel are deflected by the electric field stimulation, reducing the pass rate of the light emitted from the optical film to the display panel, and then the light is projected into filters of different colors to form an image.

[0075] In some embodiments, the light source is used to emit light. The light source and the optical film can be arranged in parallel. The light source can be located at the light incident side behind the optical film to emit light to the optical film.

[0076] In some embodiments, the display device may include a back plate 10. The back plate 10 is the main support member of the display device, and the back plate 10 may be arranged vertically on the back side of the display panel. A frame protruding forward is formed on the peripheral edge of the back plate 10. The frame is arranged circumferentially and extends around the edge of the back plate 10. The frame extends forward beyond the front side of the back plate 10, and the frame and the back plate 10 enclose a chamber with a front opening 200 for installing a light source and an optical film.

[0077] In some embodiments, the display device may include a rear shell 20. The rear shell 20 covers the back of the back plate 10, and the rear shell 20 and the back of the back plate 10 enclose a mounting cavity. A mainboard, a power board, and other driving components may be arranged in the mounting cavity. The mainboard, the power board, and other driving components are located within the enclosure of the rear cover so as to be protected by the rear shell 20. An opening 200 is provided on the rear shell 20, and a cover plate 210 is detachably covered at the opening 200.

[0078] In some embodiments, the mainboard is mainly used to operate the control system of the display device and output relevant operation instructions accordingly. The mainboard has a large number of electronic components, which mainly transmit the operation instructions output by the mainboard to the corresponding operation terminal. The power board is separately set or integrated on the mainboard and fixed on the back of the backboard 10. It is mainly used to provide a driving voltage or a stable working voltage to the mainboard and keep the output current stable when the circuit on the mainboard is working.

[0079] In some embodiments, the display device may include a base (not shown in the figure). The display device is supported on a desktop or the ground through the base. The base may include a base body, which is arranged on the bottom side of the rear shell 20, and the base body contacts the desktop or the ground to play a supporting role. The base may also include a leg, which is connected to the base body, and the leg extends vertically so that it can be connected to the rear shell 20 or the back plate 10, so that the base body can support the back plate 10 or the rear shell 20.

[0080] In some embodiments, the seat body can extend in the front-to-back direction to form a flat plate shape, thereby increasing the contact area with the desktop or the ground and providing more stability when supported.

[0081] Figure 4 A schematic structural diagram of a connecting member in a display device according to some embodiments is shown. Figure 5 The schematic diagram of the structure of a carrying handle in a display device according to some embodiments is exemplarily shown. Figure 6 The following is a schematic diagram of assembling a base and a carrying handle in a display device according to some embodiments.

[0082] See also Figures 4 to 6In some embodiments, the display device may include a lifting handle 30. The lifting handle 30 is detachably disposed in the installation cavity. The lifting handle 30 has a first installation state and a second installation state. When the lifting handle 30 is in the first installation state, one end of the lifting handle 30 is fixedly connected to the back plate 10, and the other end extends out of the back shell 20 from the opening 200 for holding. At this time, a person can hold the lifting handle 30 to lift the display device. When the lifting handle 30 is in the second installation state, the lifting handle 30 is stored in the installation cavity, and the cover plate 210 covers the opening 200, so that after use, the lifting handle 30 is prevented from being exposed. By providing the cover plate 210, the back shell 20 is kept intact, and the integrity of the appearance of the whole device is not affected. It can be understood that the difference between the lifting handle 30 in the first installation state and the second installation state is the difference in the relative position of the lifting handle 30 and the back plate 10.

[0083] In some embodiments, the carrying handle 30 may be a rod-shaped structure so that when it is in the first installation state, it can extend out of the rear housing 20 and is convenient for people to hold. It is understandable that when the carrying handle 30 is in the first installation state, the carrying handle 30 can be fixed vertically to the back plate 10, so that when people operate the carrying handle 30, it is more convenient to carry the display device and save more effort. When the carrying handle 30 is in the second installation state and is stored in the installation cavity, the carrying handle 30 can be placed in the installation cavity along the vertical direction and attached to the back plate 10.

[0084] In some embodiments, the lifting handle 30 can be disposed near the bottom of the mounting cavity of the back panel 10, so that when lifting the display device, the top of the display device can be supported by hand, and the lifting handle 30 can be used to more conveniently lift the display device.

[0085] In some embodiments, at least two lifting handles 30 may be arranged at intervals along the length direction of the back panel 10. In this way, when lifting the display device, only two persons are needed to hold the two lifting handles 30 respectively, and then hold the top of the display device to lift the display device. Compared with the prior art that requires at least four persons to lift the display device, this greatly saves labor costs.

[0086] It is understandable that at least two of the above-mentioned openings 200 are provided on the rear shell 20 corresponding to the carrying handle 30, and the opening 200 can penetrate to the bottom of the rear shell 20. Each position of the carrying handle 30 can be covered with a cover plate 210 to cover its corresponding opening 200, thereby preventing the carrying handle 30 from being exposed and protecting the integrity of the appearance of the rear shell 20. Penetrating the opening 200 to the bottom of the rear shell 20 can facilitate the insertion of the cover plate 210 from the bottom of the rear shell 20 to the top, so as to better install the cover plate 210, and also make the carrying handle 30 have a larger space for movement in the installation cavity. In this embodiment, two carrying handles 30 and two openings 200 can be provided, respectively located at the two ends of the length direction of the back plate 10 and the rear shell 20.

[0087] In some embodiments, the display device may include a base 40. The base 40 is fixed to the back of the back plate 10 and corresponds to the position of the opening 200. The base 40 may extend along the length direction of the back plate 10 or along the width direction of the back plate 10 to form a long block structure. A connecting hole 400 may be provided on the base 40, and the axial direction of the connecting hole 400 may be perpendicular to the back plate 10.

[0088] In some embodiments, when the carrying handle 30 is in the first installation state, one end of the carrying handle 30 is inserted into the connection hole 400, and the other end extends out of the rear housing 20 from the opening 200 for the user to hold. By inserting the carrying handle 30 into the connection hole 400, the wall of the connection hole 400 can be used to support the carrying handle 30, so that the carrying handle 30 can bear force.

[0089] In some embodiments, since the back panel 10 is relatively thin, directly opening the connecting hole 400 on the back panel 10 may cause the carrying handle 30 to be difficult to fix, or even damage the structure of the back panel 10. By providing a base 40 and using the base 40 to bear the force, it is possible to avoid concentrated force on the back panel 10. The thickness of the base 40 can be larger, and the connecting hole 400 can be opened deeper, so that the carrying handle 30 can be fixed more securely.

[0090] In some embodiments, the base 40 and the back panel 10 can be connected by setting a plurality of screw holes to disperse the force exerted by the base 40 on the back panel 10 and make the connection between the base 40 and the back panel 10 more secure, thereby facilitating installation and disassembly.

[0091] In some embodiments, the base 40 may be provided with a groove 410 along its length direction, the groove 410 has a certain depth, and the width of the groove 410 may be greater than the diameter of the carrying handle 30, so as to accommodate the carrying handle 30. When the carrying handle 30 is in the second installation state, the carrying handle 30 is parallel to the length direction of the groove 410, and is at least partially located in the groove 410. When the depth of the groove 410 is deep enough, the carrying handle 30 can be completely accommodated therein, providing a better storage effect. The connecting hole 400 may be provided on the bottom wall of the groove 410.

[0092] In some embodiments, the connection hole 400 may be provided with an internal thread, and the connection hole 400 is a threaded hole. Accordingly, one end of the lifting handle 30 is provided with an external thread that matches the threaded hole. When the lifting handle 30 is in the first installation state, one end of the lifting handle 30 is screwed into the connection hole 400. By screwing the lifting handle 30 and the connection hole 400, the lifting handle 30 and the base 40 can be fixed more firmly, and the lifting handle 30 can be prevented from falling off suddenly when the display device is lifted.

[0093] In some embodiments, the display device may include a connector 50. The connector 50 and the carrying handle 30 may be slidably connected, so that the carrying handle 30 can slide relative to the connector 50 in the length direction of the carrying handle 30. Further, the connector 50 is rotatably connected to the base 40 to drive the carrying handle 30 to rotate relative to the base 40, so that the carrying handle 30 can be switched between the first installation state and the second installation state.

[0094] In this embodiment, when the lifting handle 30 is rotated to the first installation state, after the lifting handle 30 is rotated into place, it can slide relative to the connecting member 50 so that one end of the lifting handle 30 can be inserted into the connecting hole 400. At this time, the lifting handle 30 can extend out of the rear shell 20 perpendicular to the back panel 10 to facilitate the user to hold the lifting handle 30.

[0095] In this embodiment, when the carrying handle 30 is rotated to the second installation state, the carrying handle 30 is connected to the connecting member 50 to be folded on the base 40, so as to be received in the installation cavity. The carrying handle 30 in the second installation state is connected by the connecting member 50 to prevent it from falling.

[0096] In some embodiments, in order to enable the carrying handle 30 to rotate without interference, when the carrying handle 30 is in the second installation state, the carrying handle 30 is located within the projection of the opening 200 on the base 40, so that when the carrying handle 30 rotates, it can pass through the opening 200 without hitting the rear shell 20.

[0097] In some embodiments, the connector 50 may include a hollow sleeve 500 . The carrying handle 30 is inserted into the hollow sleeve 500 and can slide relative to the hollow sleeve 500 .

[0098] In some embodiments, the connector 50 may include a rotating shaft 510 disposed on the outer wall of the hollow sleeve 500. The hollow sleeve 500 is rotatably connected to the base 40 via the rotating shaft 510, so that the carrying handle 30 can rotate relative to the base 40 by rotating the rotating shaft 510 to rotate between the first installation state and the second installation state.

[0099] It is understandable that, in order to prevent the lifting handle 30 from sliding out of the hollow sleeve 500 when in the second installation state, the hollow sleeve 500 may also be provided with a first limit portion 501 for limiting the sliding distance of the lifting handle 30. Within the set sliding distance, the lifting handle 30 may be screwed into or out of the connecting hole 400 in the first installation state, and remain connected to the hollow sleeve 500 in the second installation state.

[0100] In some embodiments, the diameter of the carrying handle 30 can also be set so that its diameter gradually changes along its length direction. For example, in the second installation state, the small diameter end of the carrying handle 30 can be placed close to the bottom of the back plate 10, and the small diameter end of the carrying handle 30 can be passed through the hollow sleeve 500 from top to bottom. After passing a certain distance, the diameter of the large diameter end can be set larger than the inner diameter of the hollow sleeve 500, so that the large diameter end cannot pass through the hollow sleeve 500, thereby limiting the sliding distance of the carrying handle 30 relative to the connecting member 50.

[0101] In some embodiments, the first position-limiting portion 501 may be a convex portion disposed on the inner wall of the hollow sleeve 500. Accordingly, the carrying handle 30 may include a first section 300, a second section 310, and a third section 320 sequentially disposed along its length direction, the outer diameter of the second section 310 is smaller than the outer diameters of the first section 300 and the third section 320, one end of the first section 300 is used to be inserted into the connecting hole 400, and one end of the third section 320 is used for holding. The first position-limiting portion 501 is configured to slide only in the second section 310, and the length of the second section 310 is the distance that the carrying handle 30 slides relative to the connecting member 50.

[0102] In some embodiments, the first section 300 or the third section 320 may have a slide groove 330 along its length direction. During installation, the first limiting portion 501 slides from the slide groove 330 into the second section 310, and then the lifting handle 30 is rotated to misalign the first limiting portion 501 with the slide groove 330, so that the first limiting portion 501 can be confined in the second section 310.

[0103] In some embodiments, the rotating shaft 510 may include a first rod portion 511, which may extend along the axial direction of the hollow sleeve 500, and one end of the first rod portion 511 is connected to the hollow sleeve 500. The rotating shaft 510 may also include a second rod portion 512, the other end of the first rod portion 511 is vertically connected to the second rod portion 512, and the second rod portion 512 is rotatably connected to the base 40, so that the lifting handle 30 can rotate relative to the base 40.

[0104] Figure 7 An example is shown Figure 6 Front view of . Figure 8 An example is shown Figure 7 Cross-sectional view along the BB direction. Fig. 9 An example is shown Figure 7 Cross-sectional view along CC direction. Fig.10 An example is shown Fig. 9 A partial enlarged view of point D in the middle.

[0105] For further information, see Figures 7 to 10 A positioning hole 421 is provided on the side wall of the groove 410 of the base 40, and the second rod portion 512 is rotatably connected to the positioning hole 421, thereby realizing a rotatable connection with the base 40. By setting the positioning hole 421, the second rod portion 512 can be supported, so that the rotating shaft 510 can rotate within a set range.

[0106] In some embodiments, the tops of the two opposite groove side walls of the groove 410 may be provided with mounting ears 420. The mounting ears 420 are provided protruding from the top of the groove 410. The mounting ears 420 may be provided with the above-mentioned positioning holes 421, so that the rotating shaft 510 is rotatably connected with the mounting ears 420, and the lifting handle 30 has a larger rotation range.

[0107] In some embodiments, two rotating shafts 510 are symmetrically provided relative to the hollow sleeve 500, and the second rod portions 512 of the two rotating shafts 510 are respectively rotatably connected to their corresponding positioning holes 421, so that both sides of the hollow sleeve 500 are subjected to force, and the rotation between the hollow sleeve 500 and the base 40 is smoother, and the lifting handle 30 can be set more stably when it is in the second installation state.

[0108] In some embodiments, a second limiting portion 422 may be provided in the positioning hole 421 , and the second limiting portion 422 is used to limit the rotation range of the second rod portion 512 , so that the carrying handle 30 can only rotate between the first installation state and the second installation state.

[0109] In some embodiments, the second limiting portion 422 protrudes from the inner wall of the positioning hole 421 toward the center of the positioning hole 421 to form a step structure, so that the second limiting portion 422 has a first surface 423 and a second surface 424 that are perpendicular to each other.

[0110] In some embodiments, when the lifting handle 30 is in the second installation state, one side of the second rod portion 512 abuts against the first surface 423. When the lifting handle 30 continues to rotate toward the first installation state, the second rod portion 512 rotates around the second limiting portion 422 until the lifting handle 30 is in the first installation state, at which point one side of the second rod portion 512 abuts against the first surface 423, thereby limiting the second rod portion 512 from continuing to rotate.

[0111] In some embodiments, by setting the second limit portion 422, the user does not need to pay attention to the rotation angle when rotating the lifting handle 30. As long as it cannot be rotated, it means that the lifting handle 30 has been rotated to the first installation state and the second installation state, which improves the convenience of human operation.

[0112] It is understandable that the outer peripheral wall of the end of the second rod portion 512 extending into the positioning hole 421 may include two opposite planes and two opposite arc surfaces, and the two ends of the two planes are respectively connected to the two ends of the two arc surfaces, so that the end of the second rod portion 512 extending into the positioning hole 421 can be in a runway-shaped structure. When rotating, the arc surface and the inner wall of the positioning hole 421 cooperate, so that the second rod portion 512 can rotate smoothly, and when rotating to the first installation state or the second installation state, one of the planes abuts against the first surface 423 or the second surface 424, and the two fit together, so that the second rod portion 512 cannot continue to rotate, thereby limiting the position of the lifting handle 30.

[0113] In some embodiments, a magnetic member 430 may be disposed in the groove 410. When the carrying handle 30 is in the second installation state, the magnetic member 430 is magnetically connected to the carrying handle 30, thereby tightly adsorbing the carrying handle 30 in the groove 410. It is understandable that the magnetic member 430 may be a magnet, and the carrying handle 30 is made of metal material. The magnetic member 430 may be disposed in the groove 410 at a position away from the connecting hole 400 to adsorb the end of the carrying handle 30 in the second installation state, thereby cooperating with the connecting member 50 to fold the carrying handle 30 onto the base 40, thereby preventing the carrying handle 30 from shaking and making abnormal noises.

[0114] In summary, in this embodiment, by setting the base 40 on the back plate 10, setting the connection hole 400 on the base 40, and rotatably connecting the carrying handle 30 to the base 40 through the connecting member 50, the carrying handle 30 can be rotated relative to the base 40 to rotate between the first installation state and the second installation state. When rotating to the first installation state, the carrying handle 30 is fixed through the connection hole 400. At this time, the carrying handle 30 extends out of the opening 200 on the rear shell 20, and can be held by a person to carry the display device. When rotating to the second installation state, the carrying handle 30 can be folded on the base 40, and the corresponding opening 200 on the rear shell 20 is covered by the cover plate 210, so that the carrying handle 30 is hidden and stored, so that the rear shell 20 maintains the integrity of the appearance, and improves the beauty of the whole machine.
