Description

Technical Field

[0001] This utility model relates to the field of LCD technology, and in particular to a multi-hole LCD liquid crystal module. Background Technology

[0002] Passive LCDs are liquid crystal displays that require an external light source to display images. Unlike active-matrix LCDs (such as TFT LCDs), passive LCDs do not emit light themselves; instead, they display images by reflecting ambient light or external light sources. The working principle of passive LCDs is based on the properties of liquid crystal molecules. When a voltage is applied, the liquid crystal molecules change their alignment, thereby controlling the transmission or reflection of light. When a voltage is applied to the liquid crystal layer, the liquid crystal molecules change their state, preventing light from passing through and displaying black; when no voltage is applied, the liquid crystal molecules return to their initial state, allowing light to pass through the liquid crystal layer, displaying white or color.

[0003] Currently, some LCD modules are drilled to form a single-hole structure. The application of the single-hole structure is to meet the application of some functional pointers (for example, setting a single hole in the center for the rotation indication of a mechanical pointer). However, in some application scenarios, multiple functional structures are required, which makes it difficult for conventional single-hole LCDs to meet their application requirements.

[0004] Meanwhile, in practical applications, most conventional LCD modules use fastening components to fix the frame to the external casing, with bolts being a common method. However, this method has been found to be cumbersome when removing the LCD module. Not only do specific auxiliary tools need to be used to disassemble the bolts, but the disassembled bolts also need to be kept to avoid loss (due to their small size and large number). Therefore, a multi-hole LCD module is proposed. Utility Model Content

[0005] Therefore, it is necessary to provide a multi-hole LCD module that addresses the above-mentioned technical problems by using a locking structure and locking groove to achieve the locking and fixing of the LCD components without the need for external auxiliary tools.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-hole LCD module includes a module frame and an LCD component disposed inside the module frame. A locking groove is provided on the outer side of the module frame, and a module fixing frame is fitted on the outer side of the module frame. A locking structure is installed on the inner side of the module fixing frame. The module frame can be locked inside the module fixing frame by the locking structure.

[0008] The LCD assembly includes an upper ITO glass module and a lower ITO glass module, and both the upper ITO glass module and the lower ITO glass module have a central hole and a functional hole on their surfaces.

[0009] The upper ITO glass module and the lower ITO glass module have a first frame at their opposite edges, and a second frame is provided outside the center hole and the functional hole. The liquid crystal layer is laid in the area enclosed by the first frame, except for the second frame.

[0010] Furthermore, the locking structure includes a housing fixed within the module fixing frame and a locking end slidably disposed within the housing. An elastic element is provided on the inner side of the locking end, and the locking end can be inserted into the locking groove for locking by the action of the elastic element.

[0011] The top of the locking end has an abutment arc surface, and the bottom of the locking end has a locking platform.

[0012] Furthermore, the outer opening of the locking groove facing the locking end has the same size as the height of the locking end, and a push block is also slidably provided in the locking groove.

[0013] Furthermore, the pusher has a pushing end at the bottom and a sliding end at the top;

[0014] A guide plate is fixed on one side of the sliding end for sliding engagement with the guide groove inside the module frame.

[0015] Furthermore, the pushing end slides close to the bottom of the locking groove and corresponds to the bottom of the avoidance arc surface on one side.

[0016] Furthermore, the top of the module frame has a window corresponding to the position of the sliding end, the sliding end can slide within the window, and the top of the sliding end is flush with the surface of the window.

[0017] Furthermore, a decorative cover is also fitted inside the window.

[0018] Furthermore, a fixing hole is provided on the surface of the module fixing frame, and a fixing bolt is inserted into the fixing hole;

[0019] A decorative buckle is inserted into the top of the fixing hole.

[0020] Furthermore, the elastic element is a spring, and the two ends of the spring are fixed to the side wall of the housing and the inner side of the locking end, respectively.

[0021] Furthermore, the two central holes are respectively located at the center of the upper ITO glass module and the lower ITO glass module;

[0022] Both the upper ITO glass module and the lower ITO glass module have a single functional hole.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The multi-hole LCD module provided by this utility model adds a module fixing frame and uses a locking structure to achieve a locking connection between the module fixing frame and the module frame. In this way, after assembly, there is no need to disassemble the fixing bolts on the module fixing frame. You only need to unlock the locking structure in the locking groove to remove the module frame and its internal LCD components. At the same time, no external auxiliary tools are needed, making it more practical.

[0025] By adding a functional hole to the surface of a conventional LCD component, a conventional mechanical pointer can be used to indicate movement at the center of the LCD component, while other functional pointers can also be assembled, thus broadening the applicability.

[0026] The decorative cover design allows the window area to be embedded and covered after the locking structure is inserted into the locking groove for locking. This ensures the overall aesthetics and also limits the sliding end, preventing accidental activation that could affect the stability of the locking end. Attached Figure Description

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0043] As described in the background section, bolts are the conventional method for fixing LCD modules. When it is necessary to remove the LCD module, not only are specific auxiliary tools required to disassemble the bolts, but the disassembled bolts also need to be kept to avoid loss (because the bolts are small and numerous), making the operation quite cumbersome.

[0044] To solve this technical problem, this utility model provides a multi-hole LCD liquid crystal module, which is applied to LCD modules.

[0045] For details, please refer to Figures 1-8The multi-hole LCD module specifically includes a module frame 2 and an LCD component 1 disposed inside the module frame 2. A locking groove 21 is provided on the outer side of the module frame 2, and a module fixing frame 3 is sleeved on the outer side of the module frame 2. A locking structure 4 is installed on the inner side of the module fixing frame 3. The module frame 2 can be locked inside the module fixing frame 3 by the action of the locking structure 4.

[0046] The LCD assembly 1 includes an upper ITO glass module 11 and a lower ITO glass module 12. The surfaces of the upper ITO glass module 11 and the lower ITO glass module 12 are provided with a central hole 15 and a functional hole 16.

[0047] The upper ITO glass module 11 and the lower ITO glass module 12 have a first frame 13 at their opposite edges, and a second frame 17 is provided outside the central hole 15 and the functional hole 16. The liquid crystal layer 14 is laid in the area enclosed by the first frame 13 except for the second frame 17.

[0048] The multi-hole LCD module provided by this utility model adds a module fixing frame 3 and uses a locking structure 4 to achieve a locking connection between the module fixing frame 3 and the module frame 2. In this way, after assembly, there is no need to disassemble the fixing bolts 32 on the module fixing frame 3. You only need to unlock the locking structure 4 in the locking groove 21 to remove the module frame 2 and its internal LCD component 1. At the same time, no external auxiliary tools are needed, making it more practical.

[0049] By adding a central hole 15 to the surface of the conventional LCD component 1, a functional hole 16 is added. This not only allows the conventional mechanical pointer to move and indicate at the center of the LCD component 1, but also allows for the assembly of other functional pointers, thus broadening the applicability.

[0050] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0053] Example 1

[0054] Please refer to Figures 1-8A multi-hole LCD module includes a module frame 2 and an LCD component 1 disposed inside the module frame 2. A locking groove 21 is provided on the outer side of the module frame 2. A module fixing frame 3 is sleeved on the outer side of the module frame 2. A locking structure 4 is installed on the inner side of the module fixing frame 3. The module frame 2 can be locked inside the module fixing frame 3 by the action of the locking structure 4.

[0055] The locking structure 4 includes a housing 41 fixed within the module fixing frame 3 and a locking end 42 slidably disposed within the housing 41. An elastic element 43 is provided on the inner side of the locking end 42. Under the action of the elastic element 43, the locking end 42 can be inserted into the locking groove 21 for locking. In this embodiment, the elastic element 43 is a spring, and the two ends of the spring are respectively fixed to the side wall of the housing 41 and the inner side of the locking end 42. In this embodiment, there are four locking structures 4, which are distributed at the four corners of the module frame 2. However, in actual applications, the locking structure 4 can also be designed as two or more.

[0056] like Figure 3 and Figure 5 The bottom of the module fixing frame 3 shown has a boss, which can prevent the module frame 2 from sliding out of the bottom of the module fixing frame 3.

[0057] The top of the locking end 42 has an avoidance arc surface 420, and the bottom of the locking end 42 has a locking platform 421.

[0058] The outer opening of the locking groove 21 facing the locking end 42 is the same as the height of the locking end 42, and a push block 22 is also slidably provided in the locking groove 21;

[0059] Specifically, in actual application, the module fixing frame 3 is first fixed to the corresponding area of ​​the outer casing, and then the module frame 2 with LCD component 1 is pushed into the module fixing frame 3. During the pushing process, the avoidance arc surface 420 extending outside the housing 41 will abut against the edge of the module frame 2. The locking end 42, which is subjected to the abutment force, will overcome the spring force and slide towards the inside of the housing 41. Finally, when the locking end 42 has completely slid into the inside of the housing 41, the module frame 2 can continue to be pushed in.

[0060] When the module frame 2 is fully pushed in and contacts the boss on the bottom wall of the module fixing frame 3, the locking end 42 is aligned with the locking groove 21. At this time, under the action of the spring, the locking end 42 can extend into the locking groove 21. The locking platform 421 and the locking groove 21 form a locking effect. Since the bottom of the module frame 2 is affected by the boss on the bottom of the module fixing frame 3, it cannot continue to slide downward. The locking platform 421 and the locking groove 21 are locked and cannot slide upward. Therefore, the fixing effect of the module frame 2 and the LCD component 1 inside is guaranteed.

[0061] The locking structure 4 and the locking groove 21 are locked together, eliminating the need for external auxiliary tools for installation and disassembly. Furthermore, during installation and disassembly, the locking structure 4 and the locking groove 21 do not separate from the corresponding structure, thus preventing the loss of parts.

[0062] Example 2

[0063] The multi-hole LCD liquid crystal module provided in Embodiment 1 is further optimized, specifically, as follows: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the pusher block 22 has a pushing end 220 at the bottom and a sliding end 221 at the top;

[0064] A guide plate 222 is fixed on one side of the sliding end 221 for sliding cooperation with the guide groove 223 in the module frame 2. Through the cooperation between the guide plate 222 and the guide groove 223, the push block 22 can only slide horizontally and will not wobble.

[0065] The pushing end 220 slides close to the bottom of the locking groove 21 and corresponds to the bottom of the avoidance arc surface 420 on one side;

[0066] The top of the module frame 2 has a window 224 at the position corresponding to the sliding end 221. The sliding end 221 can slide within the window 224, and the top of the sliding end 221 is flush with the surface of the window 224.

[0067] In one of the above embodiments, after the locking end 42 extends into the locking groove 21, it forms as shown in the figure. Figure 6 In the state shown, the push block 22 will be pushed away by the locking end 42, so that the sliding end 221 is in close contact with one edge of the window 224.

[0068] As a further optimization of this embodiment: a decorative cover 225 is also engaged within the window 224. After the locking end 42 extends into the locking groove 21 to complete the locking, the decorative cover 225 can then be engaged within the window 224. Figure 7 As shown, the decorative cover 225 can block the window 224 to improve the overall aesthetic effect, and at the same time limit the push block 22 to prevent the push block 22 from moving on its own due to external unstable factors, which would cause the locking end 42 to slide and affect its stable engagement in the locking groove 21.

[0069] Both the push block 22 and the decorative cover 225 have grooves on their surfaces. These grooves facilitate the use of fingers to pry and push the push block 22, and also make it easy to remove the decorative cover 225. In practical applications, protruding buttons can also be designed on the surfaces of the push block 22 and the decorative cover 225. In this embodiment, grooves are used for the design.

[0070] When the module frame 2 needs to be removed later, the decorative cover 225 is first snapped off, and then the push block 22 is pushed to slide towards the locking end 42. When the locking end 42 is resisted by the push block 22, it will overcome the elastic force of the spring and retract into the housing 41. When the locking end 42 has completely slid into the housing 41, the module frame 2 can be removed, which facilitates the actual disassembly.

[0071] Example 3

[0072] The multi-hole LCD liquid crystal module provided in Embodiment 1 or 2 is further optimized, such as... Figure 3 As shown, a fixing hole 31 is also provided on the surface of the module fixing frame 3, and a fixing bolt 32 is inserted into the fixing hole 31. A decorative buckle 33 is inserted into the top of the fixing hole 31.

[0073] When fixing the module fixing frame 3 in Embodiment 1, first place it in a suitable position, then rotate the fixing bolt 32 to connect it with the corresponding fixing area inside the housing, and finally insert the decorative buckle 33 into the fixing hole 31 to complete the sealing of the fixing bolt 32.

[0074] Example 4

[0075] The multi-hole LCD liquid crystal module provided in Embodiment 3 has been further optimized, such as... Figure 4 As shown, the LCD assembly 1 includes an upper ITO glass module 11 and a lower ITO glass module 12, and a central hole 15 and a functional hole 16 are provided on the surface of both the upper ITO glass module 11 and the lower ITO glass module 12.

[0076] The upper ITO glass module 11 and the lower ITO glass module 12 have a first frame 13 at their opposite edges, and a second frame 17 is provided outside the central hole 15 and the functional hole 16. The liquid crystal layer 14 is laid in the area enclosed by the first frame 13 except for the second frame 17.

[0077] The two central holes 15 are respectively located at the center of the upper ITO glass module 11 and the lower ITO glass module 12;

[0078] Both the upper ITO glass module 11 and the lower ITO glass module 12 have a single functional hole 16;

[0079] Since the center hole 15 is located at the center of the LCD assembly 1, it can be used for the assembly of mechanical pointers, such as using a moving mechanical pointer to indicate the current speed, time, etc., while other functional components, such as timing minutes, can be assembled in the function hole 16.

[0080] By adding a central hole 15 to the surface of the conventional LCD component 1, a functional hole 16 is added. This not only allows the conventional mechanical pointer to move and indicate at the center of the LCD component 1, but also allows for the assembly of other functional pointers, thus broadening the applicability.

[0081] The manufacturing process of the passive LCD in this embodiment is as follows: cleaning -> photoresist coating -> exposure -> development -> acid etching -> PI pad printing -> PI curing -> printing frame dots -> powder spraying -> hot pressing and bonding -> drilling the first hole -> etching -> drilling the second hole -> etching -> cutting, finally forming an LCD component 4 with the first opening 15 and the second opening 16.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.
