Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a locking structure of an iron frame under a backlight. Background Art

[0002] Currently, backlight modules typically consist of a backlight film, a backlight adhesive frame, and a lower iron frame. The upper iron frame, part of the display module, encases the backlight adhesive frame, backlight film, and display screen, while the lower iron frame is secured to the upper iron frame via a snap-fit ​​mechanism. However, in related art, even after the lower iron frame is snapped into the upper iron frame, a gap remains between the two, resulting in a loose overall structure and causing the entire module to make unusual noises when shaken. Utility Model Content

[0021] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0022] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] Unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be interpreted broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] A backlight module typically consists of a backlight film, a backlight adhesive frame, an upper iron frame, and a lower iron frame. The upper and lower iron frames wrap around the backlight adhesive frame, while the lower iron frame is secured to the upper iron frame via a snap-fit ​​mechanism. However, in related art, even after the lower iron frame is snapped into the upper iron frame, a gap still exists between the two, resulting in a loose structure and causing the entire module to make unusual noises when shaken.

[0025] In response to the above problems, an embodiment of the present application provides a locking structure for a backlight lower iron frame, which can make the connection between the lower iron frame and the upper iron frame more compact and avoid abnormal noise when shaking.

[0026] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 and Figure 2 A locking structure of a backlight lower iron frame includes: an upper iron frame 100, a backlight assembly 200 and a limiting assembly 300. The backlight assembly 200 includes a lower iron frame 210 and a fastener 220. A through hole is provided on the upper iron frame 100. The fastener 220 is arranged on the lower iron frame 210. The fastener 220 passes through the through hole. A mounting groove 211 is provided on the lower iron frame 210; the limiting assembly 300 includes a fixing spring piece 310 and a supporting spring piece 320. The fixing spring piece 310 is arranged in the mounting groove 211. The supporting spring piece 320 is arranged on the fixing spring piece 310. The supporting spring piece 320 is supported against the inner wall of the upper iron frame 100.

[0028] It should be noted that there can be multiple limit assemblies 300, and the corresponding mounting slots 211 can also be multiple. Furthermore, by providing a retaining spring 320, after the upper iron frame 100 is assembled to the lower iron frame 210, the retaining spring 320 can be held against the inner wall of the upper iron frame 100, so that the upper iron frame 100 is not loose after assembly, and the entire module will not make any abnormal noise. At the same time, because the retaining spring 320 has a certain degree of resilience, the force applied by the retaining spring 320 to the upper iron frame 100 will not cause the upper iron frame 100 to deform, ensuring the normal structure of the product.

[0029] See also Figure 1In one embodiment, an angle is formed between the supporting spring piece 320 and the bottom of the installation slot 211. Specifically, the angle ranges from 20 degrees to 25 degrees.

[0030] It should be noted that the angle formed between the supporting spring piece 320 and the bottom of the installation slot 211 should not be too large, otherwise it will break easily. Therefore, the angle in this application is between 20 degrees and 25 degrees.

[0031] See also Figure 1 In one embodiment, the limiting assembly 300 further includes a contact portion 330 , which is disposed on the supporting spring 320 , and the contact portion 330 is supported against the inner wall of the upper iron frame 100 .

[0032] It should be noted that the contact portion 330 is a contact surface for supporting the spring piece 320 and the inner wall of the upper iron frame 100 .

[0033] See also Figure 1 In one embodiment, the backlight assembly 200 further includes a plastic frame 230 , which is disposed on the upper iron frame 100 . Specifically, a void area 231 is defined on the plastic frame 230 .

[0034] It should be noted that the air-avoidance area 231 is used to install the backlight film material.

[0035] See also Figure 1 In one embodiment, the thickness of the fixing spring piece 310 is the same as the thickness of the supporting spring piece 320. Specifically, the fixing spring piece 310 has a rectangular cross-sectional structure.

[0036] It should be noted that the thickness of the fixing spring 310 is the same as the depth of the installation groove 211 .

[0037] See also Figure 3 In one embodiment, the fastener 220 includes a fastening block 221 , which is disposed on the lower iron frame 210 and has a through hole therethrough. Specifically, the fastener 220 further includes an inclined portion 222 , which is disposed on the fastening block 221 .

[0038] It should be noted that the inclined portion 222 is the inclined portion of the clamping block 221 , so that the clamping block 221 can slide into the through hole conveniently to complete the clamping.
