Description

Technical Field

[0001] The utility model relates to the technical field of LCM, in particular to a rubber frame structure for supporting an LCD. Background Art

[0002] An LCM provides a user with a standard LCD display driving interface (of different types such as 4-bit, 8-bit, VGA, etc.). The user operates according to the interface requirements to control the correct display of the LCD. Compared with glass, an LCM is a higher-integration LCD product. For small-size LCD displays, an LCM can be conveniently connected to various microcontrollers (such as single-chip microcomputers); however, for large-size or color LCD displays, it generally occupies a quite large part of the resources of the control system or cannot be controlled at all.

[0003] Currently, some LCMs mainly consist of an LCD and a rubber frame. Among them, a conventional rubber frame is a flat body. Due to the material characteristics, it will cause thermal expansion and contraction. Especially after the rubber frame shrinks and deforms, it will directly affect the assembly of the LCD and even the normal use of the product. For this reason, this application proposes a rubber frame structure for supporting an LCD. Summary of the Utility Model

[0004] Based on this, in view of the above technical problems, it is necessary to provide a rubber frame structure for supporting an LCD, in which the area within the double-sided adhesive for attaching the LCD on the rubber frame is hollowed out, and at the same time, two grooves are made on the rubber frame at the driving IC end, and the direction of the grooves is parallel to the driving IC. This solution can effectively prevent the rubber frame from shrinking and deforming.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A rubber frame structure for supporting an LCD, comprising: a rubber frame body, which has a pasting area, the rubber frame body is provided with an LCD component through the pasting area, and a double-sided adhesive is jointly pasted between the pasting area and the LCD component;

[0007] A groove body, which is distributed on the rubber frame body and is used to prevent the rubber frame from shrinking;

[0008] A through groove, which is distributed on the rubber frame body for partial exposure of the LCD component.

[0009] Further, the through groove on the rubber frame body is located within the double-sided adhesive and is formed by hollowing out along the inner side of the double-sided adhesive.

[0010] Further, the groove body is located on one side of the through groove and is arranged parallel to it.

[0011] Further, the number of the groove bodies is two, and the two groove bodies are oppositely arranged on the rubber frame body.

[0012] Further, the LCD component is composed of an upper polarizer, an upper glass sheet, a lower glass sheet, a lower polarizer, a driving IC, and a metal clip PIN together.

[0013] Further, the upper polarizer, the upper glass sheet, the lower glass sheet, and the lower polarizer are sequentially attached to each other from top to bottom to jointly form a display component;

[0014] Among them, the metal clip PINs are distributed at the edge of one side of the display component, and the driving IC is located on one side of the metal clip PINs and placed on the display component.

[0015] Further, a support unit is provided in the through groove to form the support for the overall glue frame body to form structural strength.

[0016] Further, the support unit includes support arms, and there are four support arms. The four support arms are respectively connected to the four corners of the inner wall of the through groove.

[0017] Further, one ends of the four support arms jointly extend towards the center position of the through groove and jointly form a telescopic gap;

[0018] Among them, two groups of auxiliary arms are also provided on both side walls of the through groove.

[0019] Further, the auxiliary arm includes a male arm and a female arm. One end of the male arm is fixed to one side wall of the groove body, and one end of the female arm is fixed to the other side wall of the groove body;

[0020] And there are gaps between the other ends of the male arm and the female arm relative to the side wall of the groove body, and the male arm and the female arm are arranged in parallel inside the groove body.

[0021] Compared with the prior art, the present utility model has the following beneficial effects:

[0022] The glue frame structure for supporting the LCD provided by the present utility model hollows out the area within the double-sided adhesive for attaching the LCD on the glue frame to form a through groove. At the same time, two groove bodies are also made on the glue frame, and the direction of the groove bodies is parallel to the driving IC. Through the setting of the above structure, the shrinkage deformation of the glue frame can be effectively prevented, thereby ensuring the stable assembly of the subsequent LCD and the normal use of the product;

[0023] By setting the support unit in the through groove, it not only ensures the requirement that a part of the LCD can be exposed after assembly, but also ensures the overall structural strength of the glue frame body, so that the LCD on it can be more stable during the subsequent use process after assembly.

[0038] In order to enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0039] As described in the background art, the rubber frame is a flat body. Due to the material characteristics, it will cause thermal expansion and contraction. Especially after the rubber frame shrinks and deforms, it will directly affect the assembly of the LCD and even the normal use of the product.

[0040] To solve this technical problem, the present utility model provides a rubber frame structure for supporting an LCD, which is applied to an LCM.

[0041] Specifically, please refer to Figures 1-9 , the rubber frame structure for supporting the LCD specifically includes:

[0042] A rubber frame body 1, which has a pasting area 13. The LCD component 2 is provided on the rubber frame body 1 through the pasting area 13, and a double-sided adhesive 14 is jointly pasted between the pasting area 13 and the LCD component 2;

[0043] A groove body 11, which is distributed on the rubber frame body 1 and is used to prevent the rubber frame from shrinking;

[0044] A through groove 12, which is distributed on the rubber frame body 1 for partial exposure of the LCD component 2.

[0045] The rubber frame structure for supporting the LCD provided by the present utility model effectively reduces the deformation of the rubber frame body 1 caused by its own thermal expansion and contraction by opening the groove body 11 and the through groove 12 on the conventional rubber frame body 1, thereby ensuring that the subsequent LCD component 2 can be stably assembled thereon for operation and use. At the same time, since the groove body 11 is distributed inside the pasting area 13, after the LCD component 2 is actually connected to the corresponding rubber frame body 1, a partial area of the LCD component 2 can be exposed on the other side of the rubber frame body 1. Furthermore, it is also beneficial for better heat dissipation of the LCD component 2 by better contacting the external surrounding environment during the power-on working process of the LCD component 2.

[0046] In order to enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings.

[0047] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0048] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures.

[0049] Please refer to Figures 1-6 , a rubber frame structure for supporting an LCD, a rubber frame body 1, which has a pasting area 13. An LCD component 2 is provided on the rubber frame body 1 through the pasting area 13, and a double-sided adhesive 14 is jointly pasted between the pasting area 13 and the LCD component 2. Through the setting of the double-sided adhesive 14, during the actual operation, one adhesive surface of the double-sided adhesive 14 can be first pasted on the corresponding pasting area 13, and then the LCD component 2 is aligned with the other adhesive surface of the double-sided adhesive 14 and pasted on the rubber frame body 1, thus completing the assembly of the LCD component 2;

[0050] A groove body 11, which is distributed on the rubber frame body 1 and is used to prevent the shrinkage of the rubber frame water; a through groove 12, which is distributed on the rubber frame body 1 for partial exposure of the LCD component 2;

[0051] The through groove 12 on the rubber frame body 1 is located within the double-sided adhesive 14 and is formed by hollowing out along the inner side of the double-sided adhesive 14; the groove body 11 is located on one side of the through groove 12 and is arranged parallel to it; the number of the groove bodies 11 is two, and the two groove bodies 11 are oppositely arranged on the rubber frame body 1. As Figure 1 and Figure 6 shown, the groove body 11 is arranged parallel to the driving IC 25 in the LCD component 2;

[0052] Through the setting of the pasting area 13, it not only ensures that during the process of opening the through groove 12 on the rubber frame body 1, it can assist the through groove 12 to extend and dig the groove along the inner diameter direction of its pasting area 13, ensuring the accuracy of the grooving and avoiding errors during the subsequent pasting of the double-sided adhesive 14, which may further cause the LCD component 2 to be misaligned and assembled. At the same time, it can also enable the double-sided adhesive 14 to assist the operator in better alignment operation when pasting on the rubber frame body 1, improving the pasting efficiency between the double-sided adhesive 14 and it, and can better judge whether the pasting is in place, facilitating its actual operation and use.

[0053] Further optimize the rubber frame structure for supporting the LCD provided in Embodiment 1. Specifically, as Figure 4 shown, the LCD component 2 is jointly composed of an upper polarizer 21, an upper glass sheet 22, a lower glass sheet 23, a lower polarizer 24, a driving IC 25, and a metal clip PIN 26;

[0054] The upper polarizer 21, the upper glass 22, the lower glass 23 and the lower polarizer 24 are sequentially bonded to each other from top to bottom to form a display component, wherein the metal clip PIN26 is distributed at the edge of one side of the display component, and the driver IC25 is located on one side of the metal clip PIN26 and placed on the display component.

[0055] like Figure 1 The driver IC and the metal clip PIN shown are both bound to the lower glass. Through the above structural design, after the LCD component 2 is adhered to the corresponding glue frame 1 through the double-sided adhesive 14, a part of the area on the LCD component 2 can be observed on the other side of the adhesive surface of the glue frame 1. Compared with the conventional glue frame 1, the glue frame 1 can better allow the LCD component 2 to contact with the surrounding air through the formation of the through groove 12, so that the heat generated during the operation of the LCD component 2 when it is powered on can be better dissipated, thereby ensuring the temperature of the LCD component 2 when it is working to a certain extent.

[0056] The glue frame structure supporting the LCD provided in Example 1 or 2 is further optimized, such as Figure 7 , Figure 8 and Figure 9 The plastic frame structure for supporting LCD shown in the figure has a support unit 3 in the through groove 12 for supporting the plastic frame body 1 as a whole to form structural strength;

[0057] The support unit 3 includes a support arm 31, and the support arms 31 have four support arms 31. The four support arms 31 are respectively connected to the four corners of the inner wall of the through slot 12. One end of the four support arms 31 extends toward the center of the through slot 12 and forms a telescopic gap 32. The telescopic gap 32 is set so that the ends of the multiple support arms 31 do not contact each other, thereby ensuring that when the support arms 31 themselves undergo a certain amount of thermal expansion and contraction, the ends of the support arms 31 do not conflict with each other. If the ends of the multiple support arms 31 are connected without a telescopic gap, when thermal expansion and contraction occur, the extended support arms 31 may conflict with the through slot 12, making the entire plastic frame 1 easily deformed, causing the LCD assembly 2 thereon to fall off and be damaged;

[0058] like Figure 7 As shown, since the through slot 12 has a certain height, the support arm 31 can be placed at the middle position of the height direction of the through slot 12 when it is actually arranged in the through slot 12. By setting this position, the stable connection between the support arm 31 and the plastic frame 1 can be ensured, and at the same time, a gap can be left between the support arm 31 and the LCD component 2 pasted on the plastic frame 1, which not only retains the requirement of partially exposing the LCD component 2 for its own heat dissipation, but also does not protrude from the outside of the plastic frame 1 to affect the subsequent assembly operation;

[0059] like Figure 9As shown, two sets of auxiliary arms 33 are also provided on the two side walls of the through slot 12. Through the setting of the auxiliary arms 33, they can cooperate with the support arms 31 therein to form a supporting effect on the rubber frame body 1, so that the rubber frame body 1 can be simultaneously dispersed and decompressed when local stress is applied to it.

[0060] The glue frame structure supporting the LCD provided in Example 3 is further optimized, such as Figure 7 , Figure 8 and Figure 9 The plastic frame structure supporting the LCD shown in the figure also includes an auxiliary arm 33, and the auxiliary arm 33 includes a male arm 330 and a female arm 331.

[0061] The auxiliary arm 33 includes a male arm 330 and a female arm 331. One end of the male arm 330 is fixed to one side wall of the tank body 11, and one end of the female arm 331 is fixed to the other side wall of the tank body 11. There is a gap between the other ends of the male arm 330 and the female arm 331 relative to the side wall of the tank body 11.

[0062] like Figure 9 As shown, there is a certain gap between the male arm 330 and the female arm 331, and the gap also satisfies its own thermal expansion and contraction requirements. The end of the support arm 31 is placed between the two groups of auxiliary arms 33. When the two sides of the through slot 12 on the rubber frame 1 are subjected to downward or upward pressure, the ends of the support arms 31 on both sides will be synchronously tilted upward or downward to act on the male arm 330 and the female arm 331 in the auxiliary arm 33. The pressure on the rubber frame 1 is dispersed through the friction between the support arm 31 and the auxiliary arm 33, thereby reducing the local pressure on the rubber frame 1 to ensure the overall structural strength of the rubber frame 1.

[0063] Furthermore, by arranging the support arms 31 at multiple positions, the pressure on both sides of the groove body 11 can be better transmitted to the auxiliary arms 33 to the greatest extent, so that the stress concentrated on both sides of the groove body 11 can be better dispersed on the outside of the through groove 21, avoiding the situation where the pressure on both sides of the through groove 21 is too high and easily causes the plastic frame 1 to be deformed and damaged, and also realizes the support and protection of the LCD component 2 attached to the plastic frame 1 by the double-sided adhesive 14.

[0064] The use process of the glue frame structure supporting LCD provided by the utility model is as follows:

[0065] In the actual production process of the rubber frame body 1, by digging the groove bodies 11 and the through grooves 12 on the basis of the conventional integral rubber frame body, the two groove bodies 11 after grooving can effectively avoid the deformation of the rubber frame body 1 caused by its own thermal expansion and contraction. After grooving, the through groove 12 is just formed inside the pasting area 13, and the edge of the through groove 12 coincides with the edge of the pasting area 13. Then, one adhesive surface of the double-sided adhesive 14 is pasted on the rubber frame body 1, and the assembled LCD component 2 is pasted on the other adhesive surface of the rubber frame body 1, thus completing the assembly between the LCD component 2 and the rubber frame body 1. At the same time, since the through groove 11 penetrates through the rubber frame body 1, when the LCD component 2 is pasted on it through the double-sided adhesive 14, some areas on the LCD component 2 can be observed through the other side pasted with the rubber frame body 1, so that it can be exposed to the outside to meet the better heat dissipation requirements during its own operation.

[0066] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, which can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0067] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The preferred embodiments of the present utility model are given in the drawings, but do not limit the patent scope of the present utility model.
