Description

Technical Field

[0001] The present invention belongs to the technical field of backlight modules, and particularly relates to a shared rubber frame. Background Art

[0002] In a backlight module, the rubber frame is used as a frame structure in the backlight. On the one hand, it plays a role in protecting components such as lamp strips, light guide plates, and film materials inside the backlight in the cavity, and on the other hand, it serves as a support and fixation for the liquid crystal glass. In general projects, there are two ways to use the rubber frame. One is to use one rubber frame for one project and open a set of rubber frame molds. When the backlight module is applied to panels of different sizes, such as a 50-inch panel and a 60-inch panel, two sets of rubber frame molds need to be opened. For different projects, due to different sizes, the rubber frames cannot be shared and new molds need to be opened. The problems with opening new molds are high cost and long production cycle.

[0003] The other way is to make adaptive splicing using rubber frame segments of different sizes. For example, for a 50-inch panel, use two longer rubber frame segments as the two long sides, and then use two shorter rubber frame segments as the two short sides. Or in other embodiments, it is also possible to choose to make adaptive splicing using rubber frames of the same size. For example, use four rubber frame segments of the same size as the four sides to form a square. In the above two examples, both use four rubber frame segments for splicing, and different sets of molds need to be opened for rubber frame segments of different sizes, which also has the problem of high mold cost.

[0004] Therefore, the present application proposes a shared rubber frame that can be used to make rubber frames of different sizes with only one set of molds to solve the above problems. Summary of the Invention

[0005] The research and development purpose of the present invention is to solve the problem that the existing backlight mold rubber frames cannot be shared, and rubber frames of different sizes need to be remade, resulting in high cost and long production cycle. A brief overview of the present invention is given below to provide a basic understanding of certain aspects of the present invention. It should be understood that this overview is not an exhaustive overview of the present invention. It is not intended to identify the key or important parts of the present invention, nor is it intended to limit the scope of the present invention.

[0006] Technical Solution of the Present Invention:

[0007] A shared rubber frame includes a first frame. A plurality of retaining walls are arranged on the first frame. The opening distance between two adjacent retaining walls is A, and the length of the retaining wall is B. The value range of B / A is between 0.05 and 0.4.

[0008] Further, the first frame includes a first side frame and a second side frame. The first side frame and the second side frame are connected end to end in sequence to form a rectangular first frame. The retaining walls are evenly distributed on the first side frame and the second side frame, and the first side frame and the second side frame have the same structure.

[0009] Further, a first bevel edge is machined at the end of the first frame, and a second bevel edge is machined at the end of the second frame. The first bevel edge and the second bevel edge are connected in a matching manner.

[0010] Further, the distance between the retaining wall on the first frame adjacent to the first bevel edge is less than the distance between the retaining wall on the second frame adjacent to the second bevel edge.

[0011] Further, a protrusion is machined at the end of the first frame, and a groove is correspondingly machined at the end of the second frame. The protrusion at the end of the first frame and the groove at the end of the second frame are connected in a matching manner.

[0012] Further, the length of the first frame is greater than that of the second frame.

[0013] Further, it further includes a second frame, and the second frame is connected in a matching manner with the first frame.

[0014] Further, a plurality of side wall openings are uniformly distributed on both the first frame and the second frame, and iron shell screw holes are correspondingly machined on the second frame. Bolts pass through the side wall openings and the iron shell screw holes to connect the first frame and the second frame.

[0015] Further, a plurality of side wall openings are uniformly distributed on both the first frame and the second frame, and hooks are machined at the corresponding positions of the second frame. The second frame is connected in a matching manner with the side wall openings on the first frame and the second frame through the hooks.

[0016] Further, a plurality of support surface slot openings are uniformly distributed on the first frame, and side wall protrusions are arranged at the corresponding positions of the second frame. The second frame is connected in a matching manner with the support surface slot openings on the first frame through the side wall protrusions.

[0017] Further, the support surface slot openings are located between two retaining walls and are adjacent to one of the retaining walls.

[0018] Further, the distance between the midpoints of the retaining walls adjacent to each other is P, and P = A + B.

[0019] The present invention has the following beneficial effects:

[0020] 1. For a common glue frame of the present invention, only one set of molds is required to process the glue frame for backlight modules of different sizes, saving mold costs and development time.

[0021] 2. For a common glue frame of the present invention, by connecting the combined glue frame and the frame in a matching manner, the stability of the glue frame is improved, and there are two connection methods between the long-side glue frame and the short-side glue frame. It can be connected by the matching of bevel edges, or by the matching of protrusions and grooves, improving the adaptability of glue frame assembly. Description of the Drawings

DETAILED DESCRIPTION

[0040] Embodiment 1, combination Figure 1 To explain this embodiment, a common plastic frame of this embodiment includes a first frame 1. It should be noted that the first frame 1 is formed by cutting a single plastic frame into multiple sections, such as Figures 3 to 4 As shown, taking one section of the first frame 1 as an example, there are multiple retaining walls 3 evenly distributed on it, the opening distance between two adjacent retaining walls 3 is A, the actual distance of A is the distance between the rear end face of the previous retaining wall 3 and the front end face of the adjacent retaining wall 3 behind it, the length of the retaining wall 3 is B, the actual distance of B is the distance from the front end face to the rear end face of the retaining wall 3, and the value range of B / A is between 0.05 and 0.4. The distance between the midpoints of two adjacent retaining walls 3 is P, P = A + B, ensuring that all retaining walls 3 are evenly distributed on the first frame 1 using a single plastic frame, and the distances between the retaining walls 3 are equal.

[0041] Furthermore, the first frame 1 includes a first frame 11 and a second frame 12, and the first frame 11 and the second frame 12 are connected end to end to form a rectangular first frame 1, so as to realize the assembly of the four sides of the panel. Figure 5 As shown, first use a frame strip to cut out two first frames 11 and two second frames 12 to be used, pre-assemble the two first frames 11 and second frames 12 to be used, confirm the excess part, and then cut off the excess part to obtain the first frames 11 and second frames 12 that meet the preset size of the first frame 1.

[0042] like Figure 6As shown, the first frame 11 is a long frame, and the second frame 12 is a short frame. At the connection of the first frame 11 and the second frame 12, a first bevel 111 is machined at the end of the first frame 11, and a second bevel 121 is machined at the end of the second frame 12. The slopes of the first bevel 111 and the second bevel 121 are both 45°. After the first bevel 111 and the second bevel 121 are joined, they are connected by conventional connection methods such as glue or screws. In addition, since the first frame 11 and the second frame 12 are long and short frames with different lengths cut from a single rubber frame, in this form, the first frame 11 and the second frame 12 still retain the complete retaining wall 3. The distance between the retaining wall 3 on the first frame 11 and the first bevel 111 is closer than the distance between the retaining wall 3 on the second frame 12 and the second bevel 121, and the retaining wall 3 does not interfere with the joining of the first bevel 111 and the second bevel 121.

[0043] Example 2, in combination with Figure 7 To illustrate this example, the difference between a common rubber frame in this example and that in Example 1 is that a protrusion 112 is machined at the end of the first frame 11, and a groove 122 is machined at the corresponding position at the end of the second frame 12. The protrusion 112 on the first frame 11 is connected in cooperation with the groove 122 on the second frame 12.

[0044] Example 3, in combination with Figure 2 and Figure 8 To illustrate this example, a common rubber frame in this example further includes a second frame 2. The function of the second frame 2 is to buckle the rectangular first frame 1 formed after the first frame 11 and the second frame 12 are joined. As in Example 1, when the connection between the first frame 11 and the second frame 12 adopts a bevel connection method, the combined first frame 1 can be further buckled and fixed by the second frame 2 to achieve a better fixing effect. The second frame 2 is a conventional rectangular frame, and its four frames are integrally machined.

[0045] The specific method is, as Figure 8 shown, a plurality of side wall openings 4 are machined on the side walls of the first frame 11 and the second frame 12, and screw holes 23 are machined at the corresponding positions on the second frame 2. After the first frame 11 and the second frame 12 are combined to form the first frame 1, the second frame 2 and the first frame 1 are combined. At this time, the screw holes 23 correspond to the side wall openings 4 on the first frame 11 and the second frame 12. After bolts pass through the screw holes 23 and the side wall openings 4, nuts are screwed onto the other ends of the bolts to connect and fix the first frame 1 and the second frame 2.

[0046] Example 4: In combination with Figure 9Regarding this embodiment, the difference between a common glue frame of this embodiment and that of Embodiment 3 is that a plurality of support surface slotted openings 6 are evenly distributed on the first frame 11, and side wall protrusions 22 are provided at corresponding positions of the second frame 2. When the first frame 1 and the second frame 2 are combined, the side wall protrusions 22 are snapped into the support surface slotted openings 6, which is convenient for installation and has a compact structure.

[0047] Embodiment 5, in combination with Figure 10 Regarding this embodiment, the difference between a common glue frame of this embodiment and those of Embodiments 3 and 4 is that a plurality of side wall openings 5 are evenly distributed on the side walls of the first frame 11 and the second frame 12, and hooks 21 are correspondingly arranged on the second frame 2. After the first frame 11 and the second frame 12 form the first frame 1, the second frame 2 is combined with the first frame 1, and the hooks 21 on the second frame 2 are respectively connected to the side wall openings 5 on the first frame 11 and the second frame 12, thereby connecting and fixing the first frame 1 and the second frame 2. Compared with Embodiment 3, the method of using hook connection is more convenient during installation and is easy to assemble.

[0048] Embodiment 6: In combination with Figure 2 、 Figure 4 and Figures 11 - 17 Regarding this embodiment, when a common glue frame of this embodiment is assembled with a liquid crystal glass, the opening distance A between two adjacent retaining walls 3 is used to avoid the flexible cable 13 on the liquid crystal glass. When the same set of glue frames are assembled on different liquid crystal glasses, each frame of the glue frame is appropriately truncated according to the structure. When the ratio of the length B of the retaining wall 3 to the opening distance A between two adjacent retaining walls 3 ranges from 0.05 to 0.4, the flexible cable 13 on the liquid crystal glass is placed at the opening between two adjacent retaining walls 3, and there is no interference between the retaining wall 3 and the flexible cable. As shown in Figure 16 and Figure 17 shown, when two different specifications of liquid crystal glasses are matched with the glue frame, under the action of the retaining wall opening distance A and the length B of the retaining wall 3, the retaining wall 3 can still have no interference with the flexible cable 13. The sizes of the liquid crystal glasses of Project A and Project B are different, and the number of flexible cables 13 on Project A is more than that on Project B. Therefore, the size of the liquid crystal glass of Project A is larger than that of Project B. However, when Project A or Project B is connected to the glue frame, the flexible cable 13 of Project A or Project B is located at the opening between two adjacent retaining walls 3 and does not interfere with the retaining wall 3.

[0049] This embodiment is only an exemplary illustration of the present invention and does not limit its protection scope. Those skilled in the art can also make partial changes to it, as long as they do not exceed the spirit of the present invention, they are within the protection scope of the present invention.
