Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device. Background Technology

[0002] Currently, televisions on the market are mainly installed using either a stand or a wall mount. When a television is mounted on a stand, an adapter bracket is usually installed at the bottom of the television. The adapter bracket connects to a base, which supports the television on a horizontal surface such as a table or desktop, thus achieving stand mounting.

[0003] In related technologies, the base is usually fixed to the TV adapter bracket by screws. While this fixing method is reliable, the assembly process is cumbersome because each screw needs to be assembled and tightened one by one, resulting in low production efficiency. In addition, the large number of parts leads to a higher cost for the entire TV. Utility Model Content

[0004] This application discloses a display device that simplifies the assembly process, improves production efficiency, and reduces production costs.

[0005] To achieve the above objectives, this application discloses a display device, the display device comprising:

[0006] Display module;

[0007] A backplate, the backplate covering the back side of the display module in the thickness direction of the display device;

[0008] A base is connected to the back plate and is used to support the display device on the placement surface. One of the back plate and the base is provided with a socket, and the other of the back plate and the base is provided with a tongue. The tongue is inserted from the socket to the back plate or the base to abut against it.

[0009] The back plate and the base are provided with the socket in one of the components, which is a first component, and the base is provided with the tongue in the other component, which is a second component.

[0010] The first component protrudes towards the second component to form a protrusion, the protrusion having a slot with its opening facing away from the second component, and the insertion port being formed on one side of the protrusion in the height direction of the display device and communicating with the slot.

[0011] The second component is provided with an opening, the opening direction of which extends along the thickness direction of the display device. The tongue is provided on the wall of the opening in the height direction of the display device. The tongue extends along the height direction of the display device and at least part of the tongue is located outside the opening. The tongue can be inserted into the slot from the socket. The base abuts against the back plate. The protrusion is embedded in the opening.

[0012] In the display device provided in this application embodiment, the tongue can abut against the slot wall in the thickness direction of the display device, and the base can abut against the back plate to restrict the movement of the base relative to the back plate in the thickness direction of the display device. The tongue can abut against the slot wall in the width direction of the display device to restrict the movement of the base relative to the back plate in the width direction of the display device. The protrusion can abut against the hole wall in the height direction of the display device to restrict the movement of the base relative to the back plate in the height direction of the display device. That is, it can restrict the movement of the base relative to the back plate in both the vertical and horizontal directions, making the assembly of the two more secure. Moreover, it achieves the fixing of the two in the form of a snap-fit, replacing the screw fixing method. While ensuring the fixing effect, it simplifies the assembly process of the display device, improves the production efficiency of the display device, and solves the problem that the assembly process of the display device is relatively cumbersome and costly when the base and back plate are fixed by screws in the related technology.

[0013] Furthermore, since the slot in this application is formed on a protrusion that extends from one side of the back plate and the base to the other, the insertion port for the tongue to be inserted into the slot can be formed on one side of the protrusion in the height direction of the display device. This allows the back plate or base to form an insertion port with an opening direction extending along the height direction of the display device. The opening direction of the insertion port can be approximately parallel to the insertion direction of the tongue into the slot. Compared to forming an insertion port with an opening direction extending along the thickness direction of the display device on the back plate or base for the tongue to be inserted into the slot, this method facilitates the insertion of the tongue into the slot, reduces the assembly difficulty of the base and back plate, and reduces the deformation of the tongue, thereby reducing the risk of cracks or breaks in the tongue and ensuring the reliability of the connection between the base and the back plate.

[0014] Furthermore, since the base in this application is directly fixed to the back plate, the adapter bracket is saved, the number of parts is reduced, and the structure of the display device is simplified, thereby reducing the cost of the display device. Moreover, the assembly process of the adapter bracket can be eliminated on the production line, further improving the assembly efficiency of the display device, which in turn helps to improve the production efficiency of the display device.

[0015] As an optional implementation, in an embodiment of this application, the tongue includes a first part and a second part connected in the height direction of the display device. The first part is disposed on the hole wall of the opening in the height direction of the display device and is parallel to the height direction of the display device. The second part is bent relative to the first part and located outside the opening.

[0016] In the thickness direction of the display device, the first part abuts against the slot wall, and the second part is spaced apart from the slot wall.

[0017] With this configuration, compared to the entire tongue being tilted relative to the height of the display device, the tongue has a first part parallel to the height of the display device. This first part can form a larger plane in the thickness direction of the display device, which abuts against the wall of the slot. This increases the contact area between the tongue and the slot in the thickness direction of the display device, making the contact between the tongue and the slot wall more stable and reliable, and thus providing a better limiting effect.

[0018] As an optional implementation, in an embodiment of this application, the first component is provided with a groove, the groove and the protrusion are arranged along the height direction of the display device, and the groove and the slot are kept in communication in the height direction of the display device. In the width direction of the display device, the size of the groove is larger than the size of the tongue.

[0019] This design reduces the obstruction of the backplate or base at the socket when the tongue is inserted into the slot, making it easier for the tongue to be inserted into the slot and thus reducing the assembly difficulty of the base and backplate.

[0020] As an optional implementation, in an embodiment of this application, the size of the groove is larger than the size of the protrusion in the width direction of the display device. This makes it easier to insert the tongue into the slot from the socket, further reducing the assembly difficulty of the base and back plate.

[0021] As an optional implementation, in an embodiment of this application, one of the back plate and the base protrudes along the thickness direction of the display device to form a limiting protrusion, and the other of the back plate and the base is provided with a limiting hole. The limiting protrusion and the protruding part are spaced apart in the height direction of the display device, and the limiting protrusion is embedded in the limiting hole to restrict the movement of the base relative to the back plate in the height direction of the display device.

[0022] This design allows for the assembly and fixation of the base and back plate using both the tongue and slot and the limiting protrusion and hole. It enables omnidirectional limiting of the base and back plate, making the assembly more secure and improving the reliability of the assembly.

[0023] Furthermore, when assembling the base and back panel, the end of the tongue is usually aligned with the opening of the slot, and the base is pushed along the height of the display device until the limiting protrusion is inserted into the limiting hole, at which point the assembly is complete. Since the base is lifted by the limiting protrusion during the insertion of the tongue into the slot, and no longer lifted when the limiting protrusion is inserted into the limiting hole, the insertion of the tongue can be determined by observing whether the base is lifted. In other words, the limiting protrusion and limiting bulge serve as indicators for the assembly of the base and back panel, facilitating their assembly.

[0024] As an optional implementation, in an embodiment of this application, the base moves upward relative to the back plate along the height direction of the display device to realize that when the tongue is inserted into the slot;

[0025] When the limiting protrusion is formed on the base, the limiting protrusion has an inclined surface on its upper surface in the height direction of the display device, and the size of the limiting protrusion in the height direction of the display device is reduced in the direction of the base protrusion. With this configuration, the base can move upward relative to the back plate in the height direction of the display device, so that during the insertion of the tongue into the slot, the limiting protrusion mainly contacts the back plate through the inclined surface. The limiting protrusion and the back plate have surface-to-surface contact, which can reduce the scratches on the back plate caused by the limiting protrusion compared to point-to-surface contact. It can also play a certain guiding role.

[0026] When the limiting protrusion is formed on the back plate, the limiting protrusion has an inclined surface on its lower surface in the height direction of the display device, and its size in the height direction of the display device decreases in the direction of the protrusion relative to the back plate. This configuration allows the base to move upwards relative to the back plate along the height direction of the display device, ensuring that the limiting protrusion contacts the base primarily through its inclined surface during the insertion of the tongue into the slot. This surface-to-surface contact between the limiting protrusion and the base reduces wear on the limiting protrusion compared to point-to-surface contact; it also provides a certain guiding function.

[0027] As an optional implementation, in an embodiment of this application, the base moves downward relative to the back plate along the height direction of the display device to realize that when the tongue is inserted into the slot;

[0028] When the limiting protrusion is formed on the base, the limiting protrusion has an inclined surface on its lower surface in the height direction of the display device, and the size of the limiting protrusion in the height direction of the display device is reduced in the direction of the base protrusion. With this configuration, the base can move upward relative to the back plate in the height direction of the display device, so that during the insertion of the tongue into the slot, the limiting protrusion mainly contacts the back plate through the inclined surface. The limiting protrusion and the back plate have surface-to-surface contact, which can reduce the scratches on the back plate caused by the limiting protrusion compared to point-to-surface contact. It can also play a certain guiding role.

[0029] When the limiting protrusion is formed on the back plate, the limiting protrusion has an inclined surface on its upper surface in the height direction of the display device, and its size in the height direction of the display device decreases in the direction of the protrusion relative to the back plate. This configuration allows the base to move upwards relative to the back plate along the height direction of the display device, ensuring that during the insertion of the tongue into the slot, the limiting protrusion mainly contacts the base through the inclined surface, resulting in surface-to-surface contact. Compared to point-to-surface contact, this reduces wear on the limiting protrusion from the base and also provides a certain guiding function.

[0030] As an optional implementation, in an embodiment of this application, the protrusion has a connecting end and an insertion end, the connecting end being connected to the hole wall of the opening in the height direction of the display device, and the insertion end having a smaller dimension in the width direction of the display device in the insertion direction of the tongue inserting into the slot, so as to form a guide surface on at least one side of the insertion end in the width direction of the display device.

[0031] This design allows the guide surface to guide the tongue as it is inserted into the slot, making it easier to insert the tongue and thus reducing the assembly difficulty of the base and backplate.

[0032] As an optional implementation, in an embodiment of this application, the base has a hollow portion;

[0033] The opening communicates with the hollow portion, and the protrusion extends into the hollow portion through the opening; this arrangement can both reduce the weight of the base by utilizing the hollow portion and accommodate the protrusion, preventing the protrusion from being exposed and protecting the protrusion.

[0034] Alternatively, the slot opening can communicate with the hollow portion. This arrangement allows the hollow portion to reduce the weight of the base and also accommodate the tongue, preventing it from being exposed and protecting it.

[0035] As an optional implementation, in an embodiment of this application, the protrusion includes a bottom wall and a side wall surrounding the periphery of the bottom wall. The bottom wall and the tongue abut against each other in the thickness direction of the display device. The side wall is inclined relative to the bottom wall, and the inner diameter of the slot increases along the depth direction of the slot.

[0036] Since the backplate is usually formed by injection molding, by setting the side wall at an angle relative to the bottom wall and increasing the inner diameter of the slot in its depth direction, a draft angle can be formed on the side wall of the slot, so that the backplate can be easily demolded from the mold, thereby improving the yield of the backplate.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0060] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0065] Currently, televisions, computer monitors, and other display devices on the market are mainly installed using either stand-mounted or wall-mounted designs. When a display device is stand-mounted, an adapter bracket is usually installed at the bottom of the back panel of the display device. The adapter bracket connects to a base, which supports the display device on a horizontal support surface such as a table or desktop, thus achieving stand-mounting of the display device.

[0066] However, the existence of the adapter bracket results in a large number of components in the display device, which not only leads to higher costs but also makes the assembly process more complicated, resulting in lower production efficiency. In related technologies, the adapter bracket is usually fixed to the back panel of the display device with screws, and the base is also usually fixed to the adapter bracket with screws. While this fixing method is reliable, the use of screws requires assembling and tightening each screw individually, which is a tedious assembly process, leading to low production efficiency and a large number of components, thus increasing the overall cost of the television.

[0067] To overcome the above problems, the applicant attempted to fix the base directly to the back panel, thereby saving the adapter bracket, reducing the number of parts, simplifying the structure of the display device, reducing the cost of the display device, and eliminating the assembly process of the adapter bracket on the production line, further improving the assembly efficiency of the display device, which in turn helps to improve the production efficiency of the display device.

[0068] Furthermore, by using a combination of tongues and slots, the two are fixed together in the form of a snap-fit, replacing the screw fixing method. This simplifies the assembly process of the display device while ensuring the fixing effect, improves the production efficiency of the display device, and solves the problem that the assembly process of the display device is relatively complicated and costly when the base and back plate are fixed by screws in related technologies.

[0069] However, since the slot is the socket for inserting the tongue, its opening direction usually extends along the thickness direction of the display device and forms an angle of approximately 90° with the insertion direction of the tongue into the slot. This makes it difficult for the tongue to be inserted into the slot, and the tongue usually needs to undergo a large deformation to be inserted into the slot. This leads to the risk of the tongue cracking or breaking, affecting the reliability of the connection between the base and the back plate.

[0070] In view of this, the present application provides a display device that can simplify the assembly process of the display device, thereby improving the production efficiency of the display device, while improving the connection reliability between the base and the back plate.

[0071] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0072] Please see Figure 1 , Figure 1 This is an exemplary structural diagram of a display device provided in an embodiment of this application. The display device 100 provided in this embodiment can be a television set or a computer monitor, etc.

[0073] Optionally, the display device 100 may be a plate-like structure, such as a rectangular plate-like structure, a square plate-like structure, etc.

[0074] like Figure 1 As shown, the display device 100 has a front side and a rear side arranged opposite to each other. The side of the display device 100 facing the user is the front side of the display device 100, and the distance from the rear side to the front side of the display device 100 is the thickness direction (i.e., the front-to-back direction) f1 of the display device 100. The display device 100 also has a left side and a right side arranged opposite to each other. The distance from the left side to the right side of the display device 100 is the width direction (i.e., the left-to-right direction) f2 of the display device 100. The display device 100 also has a top side and a bottom side arranged opposite to each other. The distance from the bottom side to the top side of the display device 100 is the height direction (i.e., the up-down direction) f3 of the display device 100.

[0075] In some embodiments, the display device 100 provided in this application may include a display module 11, which is used to display image information. The display module 11 may include, but is not limited to, a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display, or other displays capable of displaying images. This application does not specifically limit the implementation of such displays.

[0076] In some embodiments, the display device 100 provided in this application further includes a back plate 12, which covers the back side of the display module 11 in the thickness direction f1 of the display device 100. That is, the back plate 12 is disposed on the rear side of the display module 11 in the thickness direction f1 of the display device 100. The back plate 12 locks and fixes the display module 11 from the back side of the display module 11, thereby supporting the display module 11.

[0077] In some embodiments, the display device 100 provided in this application also includes a rear shell (not shown), which is disposed on the side of the back panel 12 away from the display module 11 and serves as a protective and decorative element.

[0078] Please see Figure 1 and Figure 2 The display device 100 provided in this application embodiment also includes a base 13, which is connected to the back plate 12 and located on the rear side of the back plate 12 away from the display module. Thus, the base 13 can be used to support the display device 100 on a desktop, tabletop, bottom surface or other placement surface to realize the mounting of the display device 100.

[0079] Since the base 13 in this application is directly fixed to the back plate 12, the adapter bracket is saved, the number of parts is reduced, the structure of the display device 100 is simplified, which is conducive to improving the generalization efficiency of the display device 100 and reducing the cost of the display device 100. Moreover, the assembly process of the adapter bracket can be eliminated on the production line, which further improves the assembly efficiency of the display device 100, and thus helps to improve the production efficiency of the display device 100.

[0080] In some embodiments, such as Figures 3 to 6 As shown, one of the back plate 12 and the base 13 is provided with a socket 123, and the other of the back plate 12 and the base 13 is provided with a tongue 132. The tongue 132 is inserted from the socket 123 to the back plate 12 or the base 13 to abut against each other, so as to realize the insertion and fixation of the two.

[0081] For ease of description, this application defines the component with a socket in the back panel and the base as the first component, and the component with a tongue in the back panel and the base as the second component.

[0082] In some embodiments, a first component protrudes towards a second component to form a protrusion 121, the protrusion having a slot with its opening facing away from the second component. For example, a back plate 12 protrudes towards a base 13 to form a protrusion 121, the protrusion 121 having a slot 122 with its opening facing away from the base 13; or, a base 13 protrudes towards a back plate 12 to form a protrusion 121, the protrusion 121 having a slot 122 with its opening facing away from the back plate 12. A socket 123 is formed on one side of the protrusion 121 in the height direction f3 of the display device 100, and the socket 123 communicates with the slot 122. Furthermore, the socket 123 can be oriented upwards or downwards.

[0083] The second component is provided with an opening 131. For example, the base 13 is provided with an opening 131, or the back plate is provided with an opening 131. The opening direction of the opening 131 extends along the thickness direction f1 of the display device. The tongue 132 is provided on the wall of the opening 131 in the height direction f3 of the display device 100. The tongue 132 extends along the height direction f3 of the display device, and at least part of the tongue 132 is located outside the opening 131. The tongue 132 can be inserted into the slot 122 from the insertion port 123. The base 13 abuts against the back plate 12, and the protrusion 121 is embedded in the opening 131.

[0084] In the above design scheme, such as Figure 7 and Figure 8 As shown, the tongue 132 can abut against the slot wall of the slot 122 in the thickness direction f1 of the display device, while the base 13 can abut against the back plate 12 to restrict the movement of the base 13 relative to the back plate 12 in the thickness direction f1 of the display device. The tongue 132 can abut against the slot wall of the slot 122 in the width direction f2 of the display device to restrict the movement of the base 13 relative to the back plate 12 in the width direction f2 of the display device. The protrusion 121 can abut against the hole wall of the opening 131 in the height direction f3 of the display device to restrict the movement of the base 13 relative to the back plate 12 in the width direction f2 of the display device. The movement of plate 12 along the height direction f3 of the display device can restrict the movement of base 13 relative to back plate 12 in the vertical and horizontal directions, making the assembly of the two more secure. Moreover, it achieves the fixation of the two in the form of a snap-fit, replacing the screw fixing method. While ensuring the fixing effect, it simplifies the assembly process of the display device, improves the production efficiency of the display device, and solves the problem that the assembly process of the display device is relatively complicated and costly when the base 13 and back plate 12 are fixed by screws in the related technology.

[0085] Furthermore, since the slot 122 in this application is formed on the protrusion 121 that protrudes from one side of the back plate 12 and the base 13, the insertion port 123 for the tongue 132 to be inserted into the slot 122 can be formed on one side of the protrusion 121 in the height direction f3 of the display device. This allows the back plate 12 or the base 13 to form an insertion port 123 with an opening direction extending along the height direction f3 of the display device. The opening direction of the insertion port 123 can be approximately parallel to the insertion direction of the tongue 132 into the slot 122. Compared to forming an insertion port 123 with an opening direction extending along the thickness direction f1 of the display device on the back plate 12 or the base 13 for the tongue 132 to be inserted into the slot 122, it is easier for the tongue 132 to be inserted into the slot 122, reducing the assembly difficulty of the base 13 and the back plate 12, and reducing the deformation of the tongue 132. This reduces the risk of cracks or breaks in the tongue 132, thereby ensuring the reliability of the connection between the base 13 and the back plate 12.

[0086] In some embodiments, there can be multiple slots 122 and tongues 132, such as two, three, four, five, etc. The multiple tongues 132 can be arranged along the height direction f3 of the display device, along the width direction f2 of the display device, or arranged in an array along both the height direction f3 and the width direction f2 of the display device. Furthermore, the multiple tongues 132 and the multiple slots 122 are configured in a one-to-one correspondence, with each tongue 132 inserted into its corresponding slot 122 to achieve the connection between them.

[0087] By providing multiple tongues 132 and multiple slots 122, the number of connection points between the base 13 and the back plate 12 can be increased, thereby further improving the connection reliability between the base 13 and the back plate 12.

[0088] In some embodiments, such as Figure 5 and Figure 6 As shown, the protrusion 121 includes a bottom wall 1211 and a side wall 1212 surrounding the periphery of the bottom wall 1211. The side wall 1212 is inclined relative to the bottom wall 1211 and extends along the depth direction of the slot 122, for example along... Figure 5 and Figure 6 In the f1 direction, the inner diameter of slot 122 increases, for example, the inner diameter of slot 122 gradually increases.

[0089] Since the back plate 12 is usually formed by injection molding, by making the side wall 1212 inclined relative to the bottom wall 1211 and increasing the inner diameter of the slot 122 in its depth direction, a draft angle can be formed on the side wall of the slot 122, so that the back plate 12 can be smoothly demolded from the mold, thereby improving the yield of the back plate 12.

[0090] In some embodiments, such as Figure 7 and Figure 8 As shown, the protrusion 121 has a connecting end 132a and an insertion end 132b. The connecting end 132a is connected to the wall of the opening 131 in the height direction f3 of the display device. In the insertion direction of the tongue 132 into the slot 122, the size of the insertion end 132b in the width direction f2 of the display device is reduced, so that a guide surface 132c is formed on at least one side of the insertion end 132b in the width direction f2 of the display device. As a result, when the tongue 132 is inserted into the slot 122 from the socket 123, the guide surface can guide the tongue 132 into the slot 122, thereby facilitating the insertion of the tongue 132 into the slot 122 and reducing the assembly difficulty of the base 13 and the back plate 12.

[0091] In some embodiments, such as Figure 9 and Figure 10 As shown, the first component is provided with a groove 124. For example, when the back plate 12 is provided with a protrusion 121, the back plate 12 is provided with a groove 124, and when the base 13 is provided with a protrusion 121, the base 13 is provided with a groove 124. The groove 124 and the protrusion 121 are arranged along the height direction f3 of the display device, and the groove 124 and the slot 122 are connected in the height direction f3 of the display device. In the width direction f2 of the display device, the size of the groove 124 is larger than the size of the tongue 132.

[0092] This configuration reduces the obstruction of the back plate 12 or the base 13 at the socket 123 when the tongue 132 is inserted into the slot 122 from the socket 123, making it easier for the tongue 132 to be inserted into the slot 122, thereby reducing the assembly difficulty of the base 13 and the back plate 12.

[0093] In some embodiments, the size of the recess 124 is larger than the size of the protrusion 121 in the width direction f2 of the display device. This makes it easier to insert the tongue 132 into the slot 122 from the socket 123, and further reduces the assembly difficulty of the base 13 and the back plate 12.

[0094] In some embodiments, the tongue 132 may include a first portion 1321 and a second portion 1322 connected in the height direction f3 of the display device. The first portion 1321 is disposed on the wall of the opening 131 in the height direction f3 of the display device and is parallel to the height direction f3 of the display device. The second portion 1322 is bent relative to the first portion 1321 and located outside the opening 131. In the thickness direction f1 of the display device, the first portion 1321 abuts against the wall of the slot 122, and the second portion 1322 is spaced apart from the wall of the slot 122.

[0095] Compared to the entire tongue 132 being tilted relative to the height direction f3 of the display device, the tongue 132 has a first part 1321 parallel to the height direction f3 of the display device. The first part 1321 can form a larger plane in the thickness direction f1 of the display device, which abuts against the groove wall of the slot 122. This increases the contact area between the tongue 132 and the slot 122 in the thickness direction f1 of the display device, thereby making the contact between the tongue 132 and the groove wall of the slot 122 more stable and reliable, and thus playing a better limiting role.

[0096] In some embodiments, such as Figure 9 and Figure 10 As shown, one of the back plate 12 and the base 13 protrudes towards the other to form a limiting protrusion 133, and the other of the back plate 12 and the base 13 is provided with a limiting hole 125. That is, when the back plate 12 protrudes towards the base 13 to form the limiting protrusion 133, the base 13 is provided with the limiting hole 125; and when the back plate 12 is provided with the limiting hole 125, the base 13 protrudes towards the back plate 12 to form the limiting protrusion 133. The limiting protrusion 133 and the protrusion 121 are spaced apart in the height direction f3 of the display device. The limiting protrusion 133 can be located above or below the protrusion 121. Furthermore, the limiting protrusion 133 is embedded in the limiting hole 125 to restrict the movement of the base 13 relative to the back plate 12 along the height direction f3 of the display device.

[0097] This configuration allows for the assembly and fixation of the base 13 and the back plate 12 using the cooperation of the tongue 132 and the slot 122, as well as the assembly and fixation of the base 13 and the back plate 12 using the cooperation of the limiting protrusion 133 and the limiting hole 125. This configuration enables omnidirectional limiting of the base 13 and the back plate 12, making the assembly of the two more secure and improving the reliability of the assembly.

[0098] Furthermore, when assembling the base 13 and the back plate 12, the end of the tongue 132 is usually aligned with the opening of the slot 122, and the base 13 is pushed along the height direction f3 of the display device until the limiting protrusion 133 is inserted into the limiting hole 125, at which point the assembly is complete. Since the base 13 is lifted by the limiting protrusion 133 during the insertion of the tongue 132 into the slot 122, and is no longer lifted by the limiting protrusion 133 when it is inserted into the limiting hole 125, it is possible to determine whether the tongue 132 is inserted correctly by observing whether the base 13 is lifted. In other words, the limiting protrusion 133 and the limiting protrusion can serve as indicators for the assembly of the base 13 and the back plate 12, facilitating their assembly.

[0099] For example, the first exemplary type, such as Figure 9 and Figure 10As shown, when the back plate 12 protrudes towards the base 13 to form a protrusion 121, the protrusion 121 has a slot 122 with the groove facing away from the base 13, and the protrusion 121 forms a downward insertion port 123 in the height direction f3 of the display device. The limiting protrusion 133 is located below the protrusion 121. When assembling the base 13 and the back plate 12, the user aligns the end position of the tongue 132 on the base 13 with the opening on the back plate 12 and pushes the base 13 upward until the limiting protrusion 133 on the base 13 is inserted into the limiting hole 125, and the assembly is completed.

[0100] After assembly, the base 13 and back plate 12 are connected. The tongue 132 abuts against the slot wall of the slot 122 in the thickness direction f1 of the display device, restricting the forward movement of the base 13 relative to the back plate 12. At the same time, the base 13 abuts against the back plate 12, restricting the backward movement of the base 13 relative to the back plate 12, thereby restricting the movement of the base 13 relative to the back plate 12 in the thickness direction f1 of the display device. The tongue 132 abuts against the slot wall of the slot 122 in the width direction f2 of the display device, restricting the movement of the base 13 relative to the back plate 12 in the width direction f2 of the display device. The protrusion 121 abuts against the lower slot wall of the opening 131 in the height direction f3 of the display device, restricting the upward movement of the base 13 relative to the back plate 12. The limiting protrusion 133 and the limiting hole 125 are used to limit the downward movement of the base 13 relative to the back plate 12, thereby restricting the movement of the base 13 relative to the back plate 12 in the height direction f3 of the display device.

[0101] When disassembling the base 13 and the back plate 12, lift the base 13 from the bottom and lift it backward so that the limiting protrusion 133 disengages from the limiting hole 125. Then remove the base 13 downward so that the tongue 132 disengages from the slot 122. The disassembly is then complete.

[0102] In the first exemplary solution described above, such as Figure 10 As shown, when the limiting protrusion 133 is formed on the base 13, the upper surface of the limiting protrusion 133 in the height direction f3 of the display device has an inclined surface 1331, and in the direction in which the limiting protrusion 133 protrudes relative to the base 13, the size of the limiting protrusion 133 in the height direction f3 of the display device is reduced.

[0103] This configuration allows the base 13 to move upward relative to the back plate 12 along the height direction f3 of the display device. During the insertion of the tongue 132 into the slot 122, the limiting protrusion 133 mainly contacts the back plate 12 through the inclined surface 1331. The limiting protrusion 133 and the back plate 12 have surface-to-surface contact, which reduces scratches on the back plate 12 caused by the limiting protrusion 133 compared to point-to-surface contact. It also provides a certain guiding function.

[0104] And such Figure 11 and Figure 12As shown, when the limiting protrusion 133 is formed on the back plate 12, the lower surface of the limiting protrusion 133 in the height direction f3 of the display device has an inclined surface 1331, and in the direction in which the limiting protrusion 133 protrudes relative to the back plate 12, the size of the limiting protrusion 133 in the height direction f3 of the display device is reduced.

[0105] This configuration allows the base 13 to move upward relative to the backplate 12 along the height direction f3 of the display device. During the insertion of the tongue 132 into the slot 122, the limiting protrusion 133 mainly contacts the base 13 through the inclined surface 1331. The limiting protrusion 133 and the base 13 have surface-to-surface contact, which reduces the wear of the limiting protrusion 133 by the base 13 compared to point-to-surface contact. It also plays a certain guiding role.

[0106] The second example is, for instance... Figure 13 and Figure 14 As shown, when the base 13 protrudes towards the back plate 12 to form a protrusion 121, the protrusion 121 has a slot 122 with the groove facing away from the back plate 12, and the protrusion 121 forms a downward insertion port 123 in the height direction f3 of the display device. The limiting protrusion 133 is located below the protrusion 121. When assembling the base 13 and the back plate 12, the user aligns the opening on the base 13 with the end position of the tongue 132 on the back plate 12 and pushes the base 13 downward until the limiting protrusion 133 on the base 13 is inserted into the limiting hole 125, and the assembly is completed.

[0107] After assembly, the base 13 and back plate 12 are connected. The tongue 132 abuts against the slot wall of the slot 122 in the thickness direction f1 of the display device, restricting the forward movement of the base 13 relative to the back plate 12. At the same time, the base 13 abuts against the back plate 12, restricting the backward movement of the base 13 relative to the back plate 12, thereby restricting the movement of the base 13 relative to the back plate 12 in the thickness direction f1 of the display device. The tongue 132 abuts against the slot wall of the slot 122 in the width direction f2 of the display device, restricting the movement of the base 13 relative to the back plate 12 in the width direction f2 of the display device. The protrusion 121 abuts against the lower hole wall of the opening 131 in the height direction f3 of the display device, restricting the downward movement of the base 13 relative to the back plate 12. The limiting protrusion 133 and the limiting hole 125 are used to limit the upward movement of the base 13 relative to the back plate 12, thereby restricting the movement of the base 13 relative to the back plate 12 in the height direction f3 of the display device.

[0108] In the second exemplary solution described above, such as Figure 14 As shown, when the limiting protrusion 133 is formed on the base 13, the lower surface of the limiting protrusion 133 in the height direction f3 of the display device has an inclined surface 1331, and in the direction in which the limiting protrusion 133 protrudes relative to the base 13, the size of the limiting protrusion 133 in the height direction f3 of the display device is reduced.

[0109] This configuration allows the base 13 to move upward relative to the back plate 12 along the height direction f3 of the display device. During the insertion of the tongue 132 into the slot 122, the limiting protrusion 133 mainly contacts the back plate 12 through the inclined surface 1331. The limiting protrusion 133 and the back plate 12 have surface-to-surface contact, which reduces scratches on the back plate 12 caused by the limiting protrusion 133 compared to point-to-surface contact. It also provides a certain guiding function.

[0110] like Figure 15 and Figure 16 As shown, when the limiting protrusion 133 is formed on the back plate 12, the upper surface of the limiting protrusion 133 in the height direction f3 of the display device has an inclined surface 1331, and in the direction in which the limiting protrusion 133 protrudes relative to the back plate 12, the size of the limiting protrusion 133 in the height direction f3 of the display device is reduced.

[0111] This configuration allows the base 13 to move upward relative to the backplate 12 along the height direction f3 of the display device. During the insertion of the tongue 132 into the slot 122, the limiting protrusion 133 mainly contacts the base 13 through the inclined surface 1331. The limiting protrusion 133 and the base 13 have surface-to-surface contact, which reduces the wear of the limiting protrusion 133 by the base 13 compared to point-to-surface contact. It also plays a certain guiding role.

[0112] In some embodiments, the limiting protrusion 133 is an elastic structure, or the surface of the limiting protrusion 133 is covered with an elastic layer (not shown). This allows the contact between the limiting protrusion 133 and the back plate 12 to be a soft contact, thereby reducing scratches on the back plate 12 by the limiting protrusion 133; or allows the contact between the limiting protrusion 133 and the base 13 to be a soft contact, thereby reducing wear on the limiting protrusion 133 by the base 13.

[0113] In some embodiments, the base 13 has a hollow portion 134. When an opening 131 is formed in the base 13, the opening 131 communicates with the hollow portion 134, and the protrusion 121 extends into the hollow portion 134 through the opening 131. This arrangement allows the hollow portion 134 to be used to reduce the weight of the base 13, and also allows the hollow portion 134 to accommodate the protrusion 121, preventing the protrusion 121 from being exposed and protecting the protrusion 121.

[0114] When the protrusion 121 is formed on the base 13, the slot of the slot 122 communicates with the hollow portion 134. This arrangement can both reduce the weight of the base 13 by utilizing the hollow portion 134 and accommodate the tongue 132, preventing the tongue 132 from being exposed and protecting the tongue 132.

[0115] In some embodiments, the base 13 may include a base plate 13a and a support column 13b. The base plate 13a is used to contact the placement surface and can extend along the thickness direction f1 of the display device. The support column 13b is connected to the base plate 13a and extends along the height direction f3 of the display device. The support column 13b is used to connect to the back plate 12. That is, one of the support column 13b and the back plate 12 is provided with a protrusion 121, and the other of the support column 13b and the back plate 12 is provided with an opening 131.

[0116] The surface of the base plate 13a in the height direction f3 of the display device is used to contact the placement surface, and the surface of the base plate 13a in the height direction f3 of the display device is larger than the surface of the support column 13b in the height direction f3 of the display device. This is equivalent to locally increasing the surface area of ​​the base 13 in contact with the placement surface, which can improve the stability of the base 13 when placed on the placement surface while meeting the lightweight design of the base 13.

[0117] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0118] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
