[0002] Traditional display products such as televisions are often used by hanging them on a wall or placing them on a TV cabinet with a base. In these two traditional usage scenarios, the front and less often the sides of the product are often displayed to the user, while the back of the product is not visible during use, so there is little attention paid to its appearance from the design side. However, with the improvement of people's living standards and the use of diversified and multi-scenario products, television products are not only the focus of a family sitting on the sofa, but can also be placed in a more random position. Therefore, the back shell of the TV, which was not valued before, may also face the user directly, which also puts higher requirements on the aesthetics of the back shell of the TV.

[0042] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0044] Traditional display devices are generally wall-mounted or placed on other structures through a base. During use, the back of the display device rarely faces the user. Therefore, the back of the traditional display device usually has structures such as air intake holes, heat dissipation holes, plug terminals and screw holes, which are not aesthetically pleasing. When the user has other requirements for the placement of the display device, for example, the display device needs to be able to be moved to any position, so that the back of the display device may appear in the user's line of sight, therefore, it is necessary to improve the back structure of the display device.

[0045] In order to solve the problem that the back structure of traditional display devices is not beautiful enough, an embodiment of the present application provides a display device, wherein a back cover is arranged on the back shell of the display device to shield the area where the structural holes and functional elements are arranged on the back shell, thereby improving the aesthetics of the back structure of the display device.

[0046] Specifically, Figures 1 to 18 As shown, an embodiment of the present application provides a display device, comprising:

[0047] The outer shell includes a frame 1 and a rear shell 2 which is arranged at the rear side of the frame 1 and connected to the frame 1, and a display screen is arranged at the front side of the frame 1;

[0048] The rear cover 3 is buckled on the outer side of the rear shell 2;

[0049] The rear shell 2 is provided with a functional area 22 , and the functional area 22 is provided with structural holes and kinetic energy elements. The rear shell 2 and the functional area 22 are correspondingly arranged to shield the functional area 22 .

[0050] The structural holes include air inlet holes, heat dissipation holes 27 and screw holes, etc., and the functional elements include plug-in terminals, interfaces and other structures. These structures are generally located in the middle and lower part of the rear shell 2. Therefore, in some embodiments of the present application, the rear cover 3 is used to shield the functional area 22, and the functional area 22 and the rear shell 2 are fixed together by a snap-fit ​​structure.

[0051] The display device provided in the embodiment of the present application shields the functional area 22 on the rear shell 2 by providing a back cover 3, thereby avoiding exposure of the structural holes and functional elements on the rear shell 2. On the one hand, the aesthetics of the back structure of the display device is improved, and on the other hand, the structural holes and functional elements are hidden by the back cover 3, thereby improving safety.

[0052] Further, combined with Figure 6 As shown, in some embodiments of the present application, the lower portion of the rear shell 2 is recessed inward to form a functional area 22 and a body area 21, and the outer surface of the body area 21 protrudes from the functional area 22. After the rear cover 3 and the rear shell 2 are assembled, the rear cover 3 is flush with the rear shell 2. That is, after the rear cover 3 is installed on the rear shell 2, the back structure of the display device is flat as a whole.

[0053] Furthermore, in some embodiments of the present application, the snap-fit ​​structure includes a first snap-fitting slot 23 and a first snap-fitting hook 31 that cooperate with each other, wherein the first snap-fitting slot 23 is arranged on the rear shell 2, and the first snap-fitting hook 31 is arranged on the rear cover 3, or the first snap-fitting slot 23 is arranged on the rear shell 2, and the first snap-fitting hook 31 is arranged on the rear cover 3.

[0054] Exemplarily, in some embodiments of the present application, the first card slot 23 is arranged on the back shell 2 and runs through the thickness direction of the back shell 2. The first card hook 31 is correspondingly arranged on the back cover 3. The shape of the first card hook 31 is L-shaped. Specifically, the first card slot 23 is arranged in the functional area 22 of the back shell 2, and the number of the first card slots 23 is multiple, and the multiple first card slots 23 are distributed at intervals on the back shell 2. Exemplarily, the number of the first card slots 23 is two, and the two first card slots 23 are arranged on the left and right sides of the upper part of the functional area 22. The number of the first card hooks 31 is equal to the number of the first card slots 23, and the first card hooks 31 and the first card slots 23 are arranged one by one.

[0055] During specific use, the first slot 23 runs through the thickness direction of the back shell 2, and the first hook 31 extends into the first slot 23. The first slot 23 only limits the movement of the first hook 31 along the front-to-back direction and the left-to-right direction, and does not limit the rotation of the first hook 31 in the first slot 23. Therefore, when only the first hook 31 cooperates with the first slot 23, the back cover 3 can rotate in the upward and downward directions relative to the back shell 2. That is to say, the back cover 3 has two states. One state is that the back cover 3 and the back shell 2 are fixed to the back shell 2 through a snap-on structure to shield the functional area 22. The other state is that the back cover 3 is deflected in a direction away from the back shell 2 through the cooperation of the first hook 31 and the first slot 23, and a certain angle is formed between the back cover 3 and the back shell 2.

[0056] Furthermore, in some embodiments of the present application, the card connection structure between the rear shell 2 and the rear cover 3 also includes a second card slot 283 and a second plug-in block 32 that cooperate with each other, the second card slot 283 is set on the rear cover 3, and the second plug-in block 32 is set on the rear shell 2, or the second card slot 283 is set on the rear shell 2, and the second plug-in block 32 is set on the rear cover 3.

[0057] Illustratively, in some embodiments of the present application, the second card slot 283 is disposed on the rear shell 2, the second plug-in block 32 is disposed on the rear cover 3, and the notch of the second card slot 283 faces the rear cover 3, and the second plug-in block 32 on the rear cover 3 is inserted into the second card slot 283, thereby realizing the cooperation between the second card slot 283 and the second plug-in block 32.

[0058] Specifically, a mounting groove 24 is provided on the rear shell 2, and the mounting groove 24 is formed by the rear shell 2 being recessed toward the front side, and a second clamping hole is provided at the bottom of the mounting groove 24, and the aperture of the second clamping hole is smaller than the diameter of the mounting groove 24, and a first step surface 241 is formed between the side wall of the mounting groove 24 and the hole wall of the second clamping hole, and a side of the rear shell 2 opposite to the first step surface 241 is a first clamping surface 242.

[0059] Combination Fig.18 As shown, the clamping structure includes a second clamping member 28, and the second clamping member 28 includes a first clamping portion 281 and a second clamping portion 282, wherein the first clamping portion 281 is inserted into the second clamping hole, and a first clamping protrusion 2813 is formed on the first clamping portion 281, the first clamping protrusion 2813 abuts against the first clamping portion 281, the second clamping portion 282 abuts against the first step surface 241, and the second clamping portion 282 has a second clamping groove 283.

[0060] The first clamping portion 281 and the second clamping portion 282 are respectively in contact with the first clamping surface 242 and the first step surface 241 , so that the second clamping member 28 is fixedly mounted on the rear housing 2 .

[0061] Specifically, in some embodiments of the present application, the first clamping portion 281 includes two symmetrically arranged first elastic arms 2811 and a first connecting arm 1812 connected between the two first elastic arms 2811, wherein the second clamping hole is in the shape of a rectangle, and the two first elastic arms 2811 are respectively arranged to fit the left and right hole walls of the second clamping hole, and the first connecting arm 1812 fixes the two first elastic arms 2811 together so that the two first elastic arms 2811 can move synchronously, and the first elastic arm 2811 and the first connecting arm 1812 are both thin-walled structures, and have a certain amount of elastic deformation when subjected to external force.

[0062] The first elastic arm 2811 protrudes outward in a direction away from the center line of the second clamping hole to form a first clamping protrusion 2813. The first elastic arm 2811, the first connecting arm 1812 and the first clamping protrusion 2813 are formed as one piece. When subjected to external force, the distance between the two first elastic arms 2811 can have a certain amount of deformation. For example, when the first clamping protrusion 2813 is squeezed, the distance between the two first elastic arms 2811 can be reduced within a certain range. After the squeezing effect disappears, the two first elastic arms 2811 can return to their original state.

[0063] When installing the first clamping portion 281, the first clamping portion 281 is moved from the slot opening of the installation slot 24 to the bottom of the slot, and the two first elastic arms 2811 fit with the hole wall of the second clamping hole and pass through the second clamping hole. When the first clamping protrusion 2813 on the first elastic arm 2811 moves to the second clamping hole, since the distance between the ends of the two first clamping protrusions 2813 is greater than the hole diameter of the second clamping hole, the first clamping protrusion 2813 will be squeezed by the hole wall of the second clamping hole, and the distance between the two first elastic arms 2811 is reduced. When the first clamping protrusion 2813 passes through the other end of the second clamping hole, the squeezing force of the second clamping hole on the first clamping protrusion 2813 disappears, and the two first elastic arms 2811 return to their original state and move away from each other. At this time, the first clamping protrusion 2813 abuts against the first clamping surface 242.

[0064] The second clamping portion 282 is arranged on the rear side of the first connecting arm 1812 and is fixedly connected to the middle part of the first connecting arm 1812. The second clamping portion 282 includes a U-shaped clamping section 2821 and second elastic arms 2822 extending outward from both ends of the U-shaped clamping section 2821. A second clamping groove 283 is formed inside the U-shaped clamping section 2821. The two second elastic arms 2822 formed at both ends of the U-shaped clamping section 2821 extend outward in a direction away from each other, and the U-shaped clamping section 2821 shrinks at the groove, so that the groove of the formed second clamping groove 283 is smaller.

[0065] The width of the second plug-in block 32 located on the back cover 3 is smaller than the width of the slot of the second card slot 283. The second plug-in block 32 is inserted into the second card slot 283 from the slot. Since the width of the second plug-in block 32 is smaller than the width of the slot of the second card slot 283, when the second plug-in block 32 cooperates with the second card slot 283, the two ends of the U-shaped card segment 2821 (that is, the slot of the second card slot 283) always abut against the second plug-in block 32, forming a constraint with the second plug-in block 32 to prevent the second plug-in block 32 from falling out of the second card slot 283.

[0066] The end of the second plug block 32 is configured as a pointed end, so that the second plug 32 can be easily inserted into the second slot 283 .

[0067] The end of the second elastic arm 2822 abuts on the first step surface 241, and the middle part of the second elastic arm 2822 arches toward the direction close to the rear cover 3. When the first clamping portion 281 passes through the second clamping hole and the first clamping protrusion 2813 abuts on the first clamping surface 242, the end of the second elastic arm 2822 abuts on the first step surface 241. The abutment between the second elastic arm 2822 and the first step surface 241 prevents the first clamping portion 281 from continuing to move forward along the second clamping hole, thereby limiting the first clamping portion 281.

[0068] The middle part of the second elastic arm 2822 is arched, so that the second elastic arm 2822 has good elastic deformation ability, and can be elastically deformed when subjected to external force, and can return to its original shape when the external force disappears.

[0069] Further, in some embodiments of the present application, the strength of the first clamping portion 281 is greater than the strength of the second clamping portion 282. Fig.18 As shown, in some embodiments of the present application, the first clamping portion 281 and the second clamping portion 282 are integrally formed and made of the same material, and the thickness tc2 of the first clamping portion 281 is greater than the thickness tc1 of the second clamping portion 282, thereby forming a strength of the first clamping portion 281 greater than the strength of the second clamping portion 282, thereby preventing the first clamping portion 281 from escaping from the second clamping hole.

[0070] Furthermore, in some embodiments of the present application, the end of the second elastic arm 2822 is an arc surface 2823. When the end of the second elastic arm 2822 abuts against the first step surface 241, it is convenient to slide on the first step surface 241. That is, during the installation of the second clip 28, the second elastic arm 2822 may slip on the first step surface 241. The end of the second elastic arm 2822 is designed as an arc surface 2823, which reduces the resistance of the end of the second elastic arm 2822 when sliding on the first step surface 241.

[0071] Furthermore, combined Fig.18 As shown, the distance between the end of the second elastic arm 2822 and the first clamping protrusion 2813 in the front-to-back direction is Lc1c2, and the distance between the first step surface 241 and the first clamping surface 242 is La2. The distance between the end of the second elastic arm 2822 and the first clamping protrusion 2813 in the front direction mentioned here refers to the distance between the end of the second elastic arm 2822 and the first clamping protrusion 2813 and the distance between the first step surface 241 and the first clamping surface 242 in the natural state, that is, the thickness of the rear shell 2 at the bottom of the mounting groove 24. The distance between the end of the second elastic arm 2822 and the first clamping protrusion 2813 in the front-to-back direction is designed to be smaller than the distance between the first step surface 241 and the first clamping surface 242, so that the second clamping component 28 is in a stressed state after being installed in the mounting groove 24, thereby effectively reducing the vibration of the second clamping component 28 in the mounting groove 24.

[0072] Furthermore, two upper and lower columns of mounting grooves 24 are provided on the rear shell 2, and each column of mounting grooves 24 includes multiple mounting grooves 24 along the left and right directions of the display device. A second clip 28 is provided in each mounting groove 24, and a second plug-in block 32 is provided at the corresponding position of the rear cover 3 for plugging and cooperating with the second clip slot 283 on the second clip 28.

[0073] Furthermore, in some embodiments of the present application, the functional area 22 of the back shell 2 is also provided with a positioning hole 25, and the corresponding position of the back cover 3 is provided with a positioning column 33 that cooperates with the positioning hole 25 for positioning the back cover 3. At the same time, after the back cover 3 is removed, the positioning hole 25 can also be used to hang the display device on the wall.

[0074] It should be noted that a positioning column 33 may be provided in the functional area 22 of the rear shell 2, and a positioning hole 25 cooperating with the positioning column 33 may be provided at a corresponding position of the rear cover 3, that is, the positions of the positioning column 33 and the positioning hole 25 may be interchangeable.

[0075] Furthermore, in some embodiments of the present application, a groove 221 is also provided on the back shell 2, and the groove 221 is arranged around the functional area 22, and the height of the bottom of the groove 221 is lower than the functional area 22; there is a rotation gap between the upper side wall of the groove 221 located between the main body area 21 and the functional area 22 and the upper end of the back cover 3, so that when only the first slot 23 and the first hook 31 cooperate with each other, the back cover 3 can rotate relative to the back shell 2, and will not interfere with the back shell 2 during the rotation process.

[0076] Specifically, in some embodiments of the present application, the first card slot 23, the heat dissipation hole 27, the air inlet hole, and some screw holes are all arranged in the sink 221, and the upper edge of the sink 221 above the functional area 22 is inclined. Fig.10 As shown, the vertical distance between the upper edge of the sink 221 above the functional area 22 and the lower edge of the first card slot 23 is La1, and the distance between the upper edge of the rear cover 3 and the end of the first hook 31 is Lb1, La1>Lb1, so as to ensure that the first hook 31 can be effectively clamped in the first card slot 23, and during the installation process, there is no mutual interference between the rear cover 3 and the rear shell 2, and the combination Fig.12 As shown, after the first hook 31 and the first slot 23 are installed, the rear cover 3 is pulled downward and rotated to make the positioning post 33 on the rear cover 3 close to the positioning hole 25. When the positioning post 33 just enters the screw hole, the second plug-in block 32 and the second slot 283 on the rear cover 3 are still in a free state. Fig.14 As shown, after the positioning column 33 enters the positioning hole 25, the second plug-in block 32 is naturally introduced into the second card slot 283, and the positioning of the entire back cover 3 is achieved by the cooperation between the first hook 31 and the first card slot 23, and the cooperation between the positioning column 33 and the positioning hole 25. The cooperation between multiple second plug-in blocks 32 and the second card slot 283 only limits the back cover 3 from bulging outward or recessing inward.

[0077] Combination Fig.16As shown, the recessed groove 221 is designed to avoid, and when the first hook 31 cooperates with the first slot 23, the maximum rotatable angle of the back cover 3 is ∠a1b1. The design of this angle enables the back cover 3 to rotate to a certain angle without relying on other hinges. The rotation angle of the back cover 3 allows the user to still perform the operation of plugging in wires without removing the back cover 3.

[0078] It should be noted that in order to enhance the structural strength of the first hook 31, a reinforcing rib is provided on the first hook 31. The first slot 23 is provided at the bottom of the sink 221 and the upper end of the functional area 22, and the first hook 31 passes through the first slot 23 and hooks on the front boss of the rear shell 2. The heat dissipation hole 27 extends from the upper end of the functional area 22 to the bottom of the sink 221. When the rear cover 3 is assembled to the functional area 22, the rear cover 22 contacts the bottom of the sink 221, so the normal heat dissipation of the heat dissipation hole 27 will not be affected.

[0079] In addition, in order to enhance the overall strength of the rear cover 3 , reinforcing ribs for enhancing the structural strength may be provided on the inner side surface of the rear cover 3 .

[0080] The arrangement of the first hook 31, the second plug-in block 32 and the positioning column 33 is as follows: Figure 3 As shown, the first hooks 31 are usually arranged on the left and right sides of the upper end of the back cover 3 , which can better connect the back cover 3 and the rear shell 2 .

[0081] Due to the effect of the first hook 31, the number of the second plug-in blocks 32 in a row near the first hook 31 is usually less than the number of the second plug-in blocks 32 in a row at the bottom, but the spacing is smaller than the spacing of the second plug-in blocks 32 at the bottom. Therefore, the bottom of the rear cover 3 is only affected by the gravity of the rear cover 3 and is relatively dispersed. The larger spacing of the second plug-in blocks 32 has little effect. In addition to being affected by gravity, the top of the rear cover 3 may also be affected by the external pulling torque caused by the backward tilt of the display device. Therefore, the spacing between the second plug-in blocks 32 is smaller. The spacing Lb3 between the positioning columns 33 can refer to the marked VESA spacing. In the case of not installing the rear cover 3, the wall mounting requirement of the display device can be achieved through the screw holes that cooperate with the positioning columns 33.
