Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a flexible LED display screen base shell. Background Technology

[0002] As a rapidly developing display medium, LED displays have been widely used in various industries. With the rapid development of LED display technology and its application in multiple fields, people now have further requirements for LED displays in terms of appearance and function, in addition to information display requirements, so that they can better adapt to the environment and look pleasing to the eye.

[0003] Common LED displays are flat, but in certain situations, curved LED displays can achieve better display effects and attract more users. Existing curved LED displays generally use flexible LED panels to achieve the curved shape. Flexible LED panels are made of thinner material to facilitate bending, and a silicone backing provides support and shaping. However, this method of using a silicone backing has limitations. The silicone's strength is insufficient, resulting in poor shaping and splicing effects. Furthermore, the silicone's softness allows the modules to be bent arbitrarily, easily damaging the internal wiring and posing a significant reliability risk. Therefore, we have introduced a flexible LED display backing. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible LED display screen base shell that can be bent into multiple angles, thereby improving the support of the LED display screen and preventing damage to the LED display screen due to arbitrary bending, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flexible LED display screen base shell includes multiple base shell strips. Each base shell strip has an arc-shaped connecting rod at both ends of its sidewall. The other side of each base shell strip has an arc-shaped groove that mates with the arc-shaped connecting rod. The upper side of the arc-shaped groove has a rectangular groove. The shell shell also includes:

[0007] A limiting mechanism includes a limiting unit and a limiting groove. The limiting unit is disposed in a rectangular groove, and a plurality of the limiting grooves are disposed on the upper side wall of the arc-shaped connecting rod to provide a limiting for the arc-shaped connecting rod.

[0008] An anti-detachment mechanism is located between the lower side of the arc-shaped connecting rod and the arc-shaped groove to prevent the arc-shaped connecting rod from detaching from the arc-shaped groove.

[0009] Among them, the curved connecting rod and the limiting mechanism can bend the display screen bottom shell, which is composed of multiple bottom shell strips, into multiple angles, thereby improving the support of the LED display screen.

[0010] As a further embodiment of this utility model, the limiting unit includes a slider, which is slidably disposed in a rectangular groove. A spring is fixedly disposed at the top of the rectangular groove, and a rotating connector is fixedly disposed at the lower end of the slider. A roller is rotatably disposed inside the rotating connector, and the roller cooperates with multiple limiting grooves.

[0011] The slider has a strip-shaped hole on its side wall, and a fixed rod is slidably mounted in the strip-shaped hole. The two ends of the fixed rod are fixedly connected to a rectangular groove.

[0012] As a further embodiment of this utility model, the anti-detachment mechanism includes an anti-detachment block, which is fixedly disposed on the lower side of the arc-shaped connecting rod wall and located away from the rectangular groove. The lower side wall of the arc-shaped groove is provided with an anti-detachment track that cooperates with the anti-detachment block.

[0013] As a further embodiment of this invention, the spring is always in a compressed state, so that the roller is always in contact with the arc-shaped connecting rod.

[0014] As a further embodiment of this invention, a silent sleeve is fixedly provided on the outside of the roller to improve the noise reduction performance of the LED display screen when it is bent.

[0015] As a further embodiment of this invention, the sound-silencing sleeve is made of high-temperature resistant rubber, which can improve its high-temperature resistance and service life.

[0016] As a further embodiment of this invention, the rotating connector is configured as a U-shaped block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This flexible LED display screen's base shell, equipped with a base shell strip, rollers, fixing rods, sliders, springs, rotating connectors, limiting grooves, arc-shaped connecting rods, anti-detachment blocks, and anti-detachment tracks, allows the flexible LED display screen to be bent. When bent, the base shell strips drive the arc-shaped connecting rods to slide outwards from the arc-shaped grooves. The arc-shaped connecting rods then drive the anti-detachment blocks to slide within the anti-detachment tracks. The springs push the sliders downwards, and the sliders, through the rotating connectors, cause the rollers to abut against the limiting grooves, thus limiting the arc-shaped connecting rods. Because the anti-detachment blocks and anti-detachment tracks work together, the arc-shaped connecting rods are prevented from detaching from the arc-shaped grooves. This invention can be bent into multiple angles, improving the support of the LED display screen and preventing damage from arbitrary bending. Attached Figure Description

[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 This utility model provides a technical solution:

[0025] A flexible LED display screen base shell includes multiple base shell strips 1, each base shell strip 1 having an arc-shaped connecting rod 8 at both ends of its sidewall, and an arc-shaped groove on the other side of the base shell strip 1 that mates with the arc-shaped connecting rod 8. A rectangular groove is provided on the upper side of the arc-shaped groove. The base shell strip 1 also includes:

[0026] The limiting mechanism includes a limiting unit and a limiting groove 7. The limiting unit is located in a rectangular groove, and multiple limiting grooves 7 are located on the upper side wall of the arc-shaped connecting rod 8 to provide limiting for the arc-shaped connecting rod 8.

[0027] An anti-detachment mechanism is located between the lower side of the arc-shaped connecting rod 8 and the arc-shaped groove to prevent the arc-shaped connecting rod 8 from detaching from the arc-shaped groove.

[0028] Among them, the bottom shell of the display screen, which is composed of multiple bottom shell strips 1, can be bent into multiple angles by the arc-shaped connecting rod 8 and the limiting mechanism, thereby improving the support of the LED display screen.

[0029] Reference Figure 3 The limiting unit includes a slider 4, which is slidably disposed in a rectangular groove. A spring 5 is fixedly disposed at the top of the rectangular groove. The spring 5 is always in a compressed state, so that the roller always abuts against the arc-shaped connecting rod 8. A rotating connecting piece 6 is fixedly disposed at the lower end of the slider 4. A roller 2 is rotatably disposed inside the rotating connecting piece 6. The roller 2 cooperates with multiple limiting grooves 7. The rotating connecting piece 6 is configured as a U-shaped block.

[0030] The slider 4 has a strip-shaped hole on its side wall, and a fixing rod 3 is slidably installed inside the strip-shaped hole. The two ends of the fixing rod 3 are fixedly connected to the rectangular groove.

[0031] Reference Figure 3 The anti-detachment mechanism includes an anti-detachment block 9, which is fixedly installed on the lower side of the arc-shaped connecting rod 8 and located away from the rectangular groove. The lower side of the arc-shaped groove is provided with an anti-detachment track 10 that cooperates with the anti-detachment block 9.

[0032] Reference Figure 3 The roller 2 is equipped with a silent sleeve to improve the noise reduction performance when the LED display is bent. The silent sleeve is made of high temperature resistant rubber, which can improve the high temperature resistance and service life.

[0033] When the flexible LED display screen is bent, the bottom shell strip 1 drives the arc-shaped connecting rod 8 to slide outward from the arc-shaped groove. The arc-shaped connecting rod 8 drives the anti-detachment block 9 to slide within the anti-detachment track 10. The spring 5 pushes the slider 4 downward. The slider 4 drives the roller 2 to abut against the limiting groove 7 through the rotating connecting piece 6, thereby limiting the arc-shaped connecting rod 8. Since the anti-detachment block 9 cooperates with the anti-detachment track 10, the arc-shaped connecting rod 8 can be prevented from detaching from the arc-shaped groove. This utility model can be bent into multiple angles, which improves the support of the LED display screen and prevents the LED display screen from being damaged by arbitrary bending.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
