Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a display screen supporting structure. Background Art

[0002] During the assembly process of existing display screens, the mechanical structure is relatively weak, especially the supporting structure on the back of some display screens. Usually, the supporting structure is screwed and fixed to the studs on the backlight module on the back of the display screen. After the display screen supporting structure is assembled with the studs of the backlight module, the back surface of the display screen lacks effective support. If external force acts on the front of the display screen, the display screen is prone to distortion, resulting in light leakage, poor uniformity, color deviation and other problems. After the structural parts and the front frame are assembled, a certain stress will be generated on the display screen to a certain extent. A very small external force can often cause the display screen to deform, thereby causing deviations in the brightness and chromaticity of the display screen, affecting the quality of the display screen. Therefore, it is necessary to optimize the supporting structure of the display screen to ensure that the display screen can maintain a certain flatness after assembly, reduce the generation of stress on the display screen, avoid its local deformation, and improve the ability of the display screen to resist external forces. Summary of the invention

[0003] The present invention provides a display screen support structure, which is easy to manufacture, quick and easy to install and disassemble, can effectively resist the impact of external forces, reduce the risks of light leakage, poor uniformity and color deviation of the display screen, and improve the quality of the display screen.

[0023] The following is combined with Figure 1-5 The present invention is described in further detail.

[0024] like Figure 1-3 As shown, a display screen support structure includes a support plate 2 arranged on the back of a display screen 1, the display screen 1 includes a display screen panel 11 and a backlight module 12 on the back of the display screen panel 11, a plurality of studs 121 are evenly distributed on the backlight module 12, a plurality of mounting holes 21 corresponding to the studs 121 are provided on the support plate 2, a plurality of elastic parts 22 protruding outwards are evenly distributed on one side of the support plate 2 close to the backlight module 12, and the end face of the elastic part 22 abuts against the back of the backlight module 12.

[0025] like Figure 3-5 As shown, the elastic portion 22 is cross-shaped as a whole, and the elastic portion 22 includes a connecting piece 221 and a spring piece 222. The connecting piece 221 protrudes from the support plate 2, and the connecting piece 221 is in the shape of an elongated strip and is arranged parallel to the support plate 2. Both ends of the connecting piece 221 are bent and extended toward the support plate 2 and are fixedly connected to the support plate 2. The spring pieces 222 are respectively fixedly connected to the opposite sides of the middle of the connecting piece 221. The two spring pieces 222 are coplanar with the connecting piece 221. The ends of the two spring pieces 222 are respectively provided with raised portions 2221 extending toward the backlight module 12, and the raised portions 2221 are against the back of the backlight module 12.

[0026] The spring piece 222 is provided with a protrusion 2221 to ensure that the elastic part 22 effectively contacts the backlight module 12 . The spring pieces 222 on both sides of the connecting piece 221 are a seesaw structure and can adapt to the uneven surface of the back of the backlight module 12 .

[0027] In this embodiment, the protrusion 2221 is in the shape of a spherical crown.

[0028] In order to ensure the softness of the protrusion 2221 against the backlight module 12 and avoid the protrusion 2221 applying pressure to the tip of the backlight module 12, in one embodiment, the end of the protrusion 2221 is a contact surface 2222 of the parallel spring 222, and the contact surface 2222 of the protrusion 2221 is against the back side of the backlight module 12.

[0029] In order to reduce production costs and assembly processes, the elastic portion 22 and the support plate 2 are integrally formed, and there is no need to additionally rivet the elastic portion 22 .

[0030] In another embodiment, the support plate 2 is made of steel plate, and the elastic part 22 is formed by stamping at one time. This production method is convenient for processing, reduces assembly steps, and the elastic part 22 formed by stamping at one time does not require additional riveting.

[0031] like Figure 4 As shown, in order to improve the strength of the support plate 2 , ribs 23 extending toward the display screen 1 are provided around the support plate 2 .

[0032] like Figure 4 , 5 As shown, both ends of the connecting piece 221 are respectively provided with a width-reducing portion 2211 for reducing the width of the connecting piece 221 .

[0033] Specifically, the width-reducing portion 2211 of this embodiment includes U-shaped grooves 2212 symmetrically distributed on both sides along the length direction of the connecting piece 221 , and the openings of the two U-shaped grooves 2212 face outward and communicate with the outside.

[0034] By providing a narrowing portion 2211 at both ends of the connecting piece 221 for reducing the width of the connecting piece 221, the width of the two ends of the connecting piece 221 is reduced, and the spring pieces 222 on both sides of the connecting piece 221 can maintain the balance of the seesaw. When only one protrusion 2221 of the two spring pieces 222 in an elastic portion 22 abuts against the backlight module 12, the connecting piece 221 can rotate slightly, so that the protrusion 2221 on the other spring piece 222 also abuts against the backlight module 12. The protrusions 2221 on the two spring pieces 222 can adapt to different heights through the narrowing portion 2211 of the connecting piece 221. At this time, the narrow connecting piece 221 between the two U-shaped grooves 2212 is in a twisted state and can withstand a certain supporting force.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
