Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display back cover and a liquid crystal display. Background Technology

[0002] Liquid crystal displays (LCDs) are widely used as key display devices in consumer electronics, commercial displays, and industrial control. As the demand for display devices continues to grow across industries, the production scale of LCDs continues to expand, placing higher demands on their production efficiency and assembly convenience.

[0003] In an LCD monitor, the back cover serves as the outer protective shell, primarily responsible for protecting internal components, supporting the exterior design (such as shape and color scheme), and providing openings for interfaces. The back panel, on the other hand, is the core internal support component, typically made of metal (such as aluminum alloy or steel plate) or high-strength engineering plastics. It provides a mounting surface for the LCD panel, backlight module, driver circuit board, and other components, ensuring their stable position.

[0004] Correspondingly, the connection between the back cover and the back panel is a crucial step in the assembly process of an LCD display. Currently, the industry commonly uses bolts or clips to achieve this connection. The bolt structure requires corresponding screw holes on both the back cover and the back panel, with the bolt being passed through and tightened to secure it. In actual production, it has been found that the assembly process for this bolt structure is quite complex. Precise alignment of the screw holes and tightening are necessary, which is not only time-consuming and labor-intensive but also requires a certain level of operator skill. In large-scale assembly line production, this complex assembly process can easily impact overall production efficiency.

[0005] In addition, although the snap-fit ​​structure can connect the back shell and the back panel in large-size LCD displays, the large size of the back shell requires multiple snap-fits to be set on the edge. Due to the influence of component processing accuracy, material rigidity and deformation during assembly, the snap-fit ​​position is prone to deviation, which means that the snap-fits need to be repeatedly adjusted during the snap-fit ​​process, increasing the operation steps and time costs. It is difficult to meet the needs of efficient assembly in mass production.

[0006] Therefore, the above problems urgently need to be solved. Utility Model Content

[0007] The purpose of this utility model is to provide a display back cover and a liquid crystal display to simplify the assembly process, improve production efficiency, and reduce maintenance and time costs during use.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A display back cover, the display back cover being connectable to the back panel of a display, the display back cover including a back cover body, an operation panel, and connecting components, wherein:

[0010] The rear shell body has an open side to form an opening, and the other sides are provided with stepped surfaces, each of which includes a top surface and a side surface.

[0011] The multiple edges of the back plate can be respectively placed on and bonded to the top surface of the multiple steps, and respectively abut against the side surface of the multiple steps;

[0012] The operating panel can close the opening, and the operating panel and the sides of the plurality of steps form a limiting frame, which is configured to limit the periphery of the back plate.

[0013] The control panel and the rear shell body are detachably connected via the connecting assembly.

[0014] Preferably, the edge of the rear shell body is integrally formed with a support plate, and the support plate has the stepped surface.

[0015] Preferably, both the rear shell body and the support plate are made of metal.

[0016] Preferably, the cross-section of the support plate is L-shaped, and one side of the support plate is attached to the edge of the rear shell body.

[0017] Preferably, the edge of the opening is provided with a mounting surface, and the operating plate can be partially attached to the mounting surface.

[0018] Preferably, the connecting assembly includes a bolt, a through hole and a threaded hole that can communicate with each other, wherein:

[0019] The through hole is provided on the operating plate, the threaded hole is provided on the mounting surface, and the bolt can pass through the through hole and be screwed into the threaded hole to lock the operating plate onto the mounting surface.

[0020] Preferably, multiple through holes are distributed along the length of the operating plate, and multiple threaded holes and bolts are correspondingly provided.

[0021] Preferably, the connection assembly further includes a snap-fit ​​member and a mating member that can be adapted to snap into each other, the snap-fit ​​member being disposed on the mounting surface, and the mating member being disposed on the surface of the operation plate facing the mounting surface.

[0022] Preferably, multiple mating parts are distributed along the length of the operating plate, and multiple locking parts are correspondingly provided, with each locking part located between two threaded holes.

[0023] A liquid crystal display (LCD) includes a back panel and a display back cover as described above, the display back cover being connectable to the back panel.

[0024] The beneficial effects of this utility model are:

[0025] 1. The display back cover provided by this utility model is constructed by placing and bonding the multiple edges of the back plate to the top surfaces of multiple steps on the back cover body, and then abutting against the sides of the multiple steps. Compared with the bolt structure commonly used in the prior art, the bonding method eliminates the need for precise alignment of screw holes and tightening operations required by bolt connections, greatly simplifying the assembly process. When applied to large-scale LCD production lines, it reduces complex operations in the assembly process, thereby improving overall production efficiency.

[0026] 2. Because bolted structures require a certain level of operator skill, inexperienced operators may further prolong assembly time due to difficulties in aligning the bolt holes and tightening them. However, by bonding the back plate to the top surface of the step and abutting against the side of the step, and by detachably connecting the operating plate to the rear shell body via a connecting assembly, the assembly process becomes relatively simple. In actual production scenarios, even relatively inexperienced operators can easily complete the connection between the rear shell and the back plate, reducing reliance on operator skill.

[0027] 3. Furthermore, the back panel is bonded to the top surface of the steps and abuts against the side of the steps. Additionally, the operating panel and multiple step sides form a limiting frame to restrict the perimeter of the back panel. This limiting frame provides a precise positioning reference for the back panel assembly, effectively avoiding positional deviations caused by factors such as component machining accuracy, material rigidity, and deformation during assembly. In the actual assembly process of large-size LCD displays, there is no need for repeated alignment adjustments as with snap-fit ​​structures. This improves assembly accuracy, reduces operational steps and time costs, increases assembly efficiency, and better meets the needs of high-efficiency assembly in large-scale production.

[0028] 4. The control panel and the rear shell are detachably connected via a connecting assembly, allowing for easy disassembly of the control panel to operate the internal components when maintenance or replacement is required, thus increasing the product's convenience in maintenance and use.

[0037] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0038] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0040] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0041] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0042] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0043] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0044] Please see Figures 1 to 4 This embodiment provides a display back cover that can be connected to the back panel 100 of the display. The display back cover includes a back cover body 1, an operation panel, and a connecting component 2.

[0045] The rear shell body 1 has an open side forming an opening 11, while the other sides are provided with stepped surfaces, each including a top surface 12 and a side surface 13. Multiple edges of the back panel 100 can be placed and adhered to multiple top surfaces 12 and abut against multiple side surfaces 13. The operating plate can close the opening 11, and the operating plate and the multiple side surfaces 13 form a limiting frame, which is configured to limit the periphery of the back panel 100. The operating plate and the rear shell body 1 are detachably connected via a connecting assembly 2.

[0046] Understandably, the multiple edges of the back plate 100 are respectively placed and bonded to the multiple stepped top surfaces 12 of the rear shell body 1, and respectively abut against the multiple stepped side surfaces 13. Compared with the bolt structure commonly used in the prior art, the bonding method eliminates the need for precise alignment of screw holes and tightening operations required by bolt connections, greatly simplifying the assembly process. When applied to large-scale LCD production lines, it reduces complex operations in the assembly process, thereby improving overall production efficiency.

[0047] It is also understandable that, since the bolt structure requires a certain level of operator skill, inexperienced operators may further prolong assembly time due to difficulties in aligning the bolt holes and tightening them. However, by bonding the back plate 100 to the top surface 12 of the step and abutting against the side surface 13 of the step, and by detachably connecting the operating plate to the rear shell body 1 via the connecting component 2, the assembly process is relatively simple. In actual production scenarios, even relatively inexperienced operators can easily complete the connection operation between the rear shell and the back plate 100, reducing the reliance on operator skill.

[0048] Furthermore, the back panel 100 is bonded to the top surface 12 of the step and abuts against the side surface 13 of the step. The operating panel and multiple side surfaces 13 form a limiting frame to restrict the periphery of the back panel 100. This limiting frame provides a precise positioning reference for the assembly of the back panel 100, effectively avoiding positional deviations caused by factors such as component machining accuracy, material rigidity, and deformation during assembly. In the actual assembly process of large-size LCD displays, there is no need for repeated alignment adjustments as with snap-fit ​​structures. This improves assembly accuracy, reduces operating steps and time costs, increases assembly efficiency, and better meets the needs of high-efficiency assembly in large-scale production.

[0049] It is worth noting that in practical applications, LCD displays may experience internal component damage during use, requiring maintenance or replacement. The control panel and the rear shell 1 are detachably connected via the connecting component 2, allowing for easy disassembly of the control panel to operate the internal components when maintenance or replacement is needed, thus increasing the product's convenience in maintenance and use.

[0050] To enhance the structural strength of the monitor's back cover, a support plate 14 is integrally formed on the edge of the back cover body 1. The support plate 14 has a stepped surface, which makes the support plate 14 and the back cover body 1 form a single continuous structure. This avoids the splicing gaps and connection stresses of split components (such as separately processing the support plate 14 and then connecting it to the back cover), and significantly improves the overall rigidity.

[0051] In this embodiment, both the rear shell body 1 and the support plate 14 are made of metal. Metal materials (such as aluminum alloys and steel plates) have significantly better tensile strength and rigidity than engineering plastics. Furthermore, the metal material can be integrally formed from the support plate 14 and the rear shell body 1 using a bending process, creating a continuous metal structure that effectively resists deformation caused by external forces during assembly or by gravity during long-term use. In practical applications, the bending angle and dimensional accuracy of the stepped surface can be precisely controlled using molds or CNC bending machines to ensure the perpendicularity and flatness of the top surface 12 (support surface) and the side surface 13 (positioning surface) of the step when the back plate 100 is installed. This avoids installation misalignment of the back plate 100 due to structural flexibility deformation, making it particularly suitable for large-size displays requiring high-rigidity support.

[0052] It should be noted that in other embodiments, the carrier can also be integrally formed with the rear shell body 1 by injection molding using plastic material, or the carrier plate 14 and the rear shell body 1 can be separately processed from metal material, and then the two are welded and / or riveted. This embodiment will not elaborate on this.

[0053] Preferably, the cross-section of the support plate 14 is L-shaped, with one side of the support plate 14 adhering to the edge of the rear shell body 1. The two vertical surfaces of the L-shape form the top surface 12 and the side surface 13 of the step, respectively. The top surface 12 of the step is used to support the edge of the back plate 100 and is fixed by adhesive, while the side surface of the step serves as a limiting reference surface and abuts against the edge of the back plate 100. When the back plate 100 is supported by the top surface 12 of the step, its weight and external impact force (such as pressing during assembly and vibration during transportation) are transmitted to the side surface 13 of the step through the top surface 12 of the step. The side of the support plate 14, which is adhering to the edge of the rear shell body 1, evenly distributes the load to the entire edge area of ​​the rear shell body 1, thereby further improving the structural strength of the rear shell body 1 and preventing deformation of the edge of the rear shell body 1 due to local stress during assembly.

[0054] To improve assembly convenience, the edge of the opening 11 is provided with a mounting surface 15, allowing the control panel to be partially fitted onto the mounting surface 15. This design provides the mounting surface 15 with a clear positioning reference for the control panel, enabling initial fixation through partial fitting, reducing alignment difficulties during assembly and improving assembly efficiency. Especially in mass production, this reduces manual calibration costs. In practical applications, the control panel typically houses buttons such as switches, color adjustment buttons, and volume control buttons, and is located on the underside of the rear housing body 1. Using the mounting surface 15 as the positioning reference for the control panel ensures strict alignment between the switch, color adjustment, and volume control buttons and the rear housing body 1.

[0055] Specifically, the connecting component 2 includes bolts, a through hole, and a threaded hole 21. The through hole is located on the operating plate, and the threaded hole 21 is located on the mounting surface 15. The bolt passes through the through hole and is screwed into the threaded hole 21 to lock the operating plate onto the mounting surface 15. It is understood that the bolt connection, through preload, tightly fits the operating plate to the mounting surface 15, thereby improving the reliability of the connection. Furthermore, during maintenance, only the corresponding bolts need to be removed with a screwdriver to separate the operating plate from the rear housing 1, eliminating the need to disassemble the entire machine and making operation easier.

[0056] Furthermore, multiple through holes are distributed along the length of the operating plate, and multiple threaded holes 21 and corresponding bolts are provided. The multiple bolts evenly distributed along the length of the operating plate can further improve the reliability of the connection between the operating plate and the rear housing body 1. In addition, the multiple bolts evenly distributed along the length of the operating plate can provide linear support for the operating plate, thereby converting the local load generated when the button is pressed into a linearly distributed support force, thus improving the service life of the operating plate.

[0057] To further enhance assembly convenience, the connecting assembly 2 also includes a snap-fit ​​element 22 and a mating element that can be adapted to engage. The snap-fit ​​element 22 is disposed on the mounting surface 15, and the mating element is disposed on the surface of the operating plate facing the mounting surface 15. The snap-fit ​​structure of the snap-fit ​​element 22 and the mating element provides an initial positioning reference during assembly, allowing the through hole on the operating plate and the threaded hole 21 on the mounting surface 15 to be quickly aligned without repeated manual adjustments. For example, the snap-fit ​​element 22 can be a protrusion (such as a buckle or guide post), and the mating element can be a corresponding groove (such as a slot or guide hole). When the two are inserted, their positions are constrained by geometric shapes to ensure the coaxiality of the axes of the through hole and the threaded hole 21, avoiding the difficulty of bolts passing through or tilted installation due to manual alignment deviations.

[0058] More importantly, the snap-fit ​​structure provides temporary mechanical locking before the bolts are tightened, preventing the control plate from shifting during installation and ensuring that bolts can be tightened with one hand, reducing reliance on tooling or auxiliary tools. For example, after the control plate is attached to the mounting surface 15, the snap-fit ​​part 22 automatically locks into place with the mating part, and the control plate will not slide due to gravity or contact force. At this point, only the bolts need to be tightened in sequence, avoiding the inconvenience of needing both hands to support and align them.

[0059] In scenarios with multiple bolt holes, multiple mating parts are distributed along the length of the operating plate, and multiple locking parts 22 are correspondingly provided, with each locking part 22 located between two threaded holes 21. This arrangement, with one locking part 22 between each two threaded holes 21, creates an alternating layout of positioning points and bolt tightening points. This ensures that each bolt tightening area of ​​the operating plate along its length is pre-constrained by the locking structures on both sides, preventing the operating plate from tilting due to localized tension during single bolt tightening.

[0060] This embodiment also provides a liquid crystal display (LCD), which includes a back panel 100 and the aforementioned display back cover. The display back cover can be connected to the back panel 100. It is understood that the LCD assembly process including the aforementioned display back cover is simple and has high production efficiency.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
