Description

Bottom shell of LED display screen module

Technical Field

The utility model relates to the technical field of LED display screens, in particular to a bottom shell of an LED display screen module.

Background

The outdoor LED module comprises a bottom shell, a face shield column, a PCBA and the like. Inside PCBA arranged in the drain pan, for guaranteeing that the drain pan can satisfy the requirement of thermal energy, there was the gap between drain pan and the PCBA for four lateral walls of drain pan are very thin along the wall thickness. With the smaller and smaller distance between the outdoor points, the wall thickness of the peripheral edge of the bottom shell is thinner and thinner, generally below 0.5mm, even about 0.25 mm. Meanwhile, as the dot spacing is reduced, the diameter and wall thickness of the mask post are also smaller. In actual production, the drain pan is through injection moulding, and the producer of drain pan has certain distance, far even has thousands of kilometers with the producer of module. When the bottom shell is packed, the bottom shell is generally packed in a stacking mode, namely, the upper bottom shell layer is arranged on the lower bottom shell, and the mask column or the edge of the upper bottom shell is in contact with the back surface of the lower bottom shell. The drain pan is in long-distance transport, often takes place around phenomenon such as the border damage, warp, fracture, and the face guard post of drain pan often appears warping, corner collapse, fracture and the like phenomenon, and the qualification rate of drain pan seriously reduces in the transportation, seriously influences subsequent module production, has further improved the material cost of module. In view of this, the present application is proposed.

SUMMERY OF THE UTILITY MODEL

In order to solve at least one technical problem in the background art, the utility model provides a bottom shell of an LED display screen module.

The utility model provides a bottom shell of an LED display screen module, which comprises:

the device comprises a body, a supporting piece is arranged on one surface of the body, and a limiting piece matched with the supporting piece is arranged on the other surface of the body; wherein the content of the first and second substances,

when one bottom shell is stacked on the other bottom shell, the supporting piece on one bottom shell abuts against the limiting piece on the other bottom shell;

four side walls of one bottom shell are not contacted with four side walls of the other bottom shell; and/or the presence of a gas in the gas,

the mask column on one of the bottom shells is not in contact with the other bottom shell.

Detailed Description

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments in the present application may be combined with each other; the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left" and "right", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the positions or elements referred to must have specific orientations, be constructed in specific orientations, and be operated, and thus are not to be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 to 4, the bottom case of an LED display screen module according to the present invention includes:

the device comprises a body 1, wherein a support part 2 is arranged on one surface of the body 1, and a limiting part 3 matched with the support part 2 is arranged on the other surface of the body 1; wherein the content of the first and second substances,

when one of the bottom cases is stacked on the other bottom case, the supporting member 2 of one of the bottom cases abuts against the stopper 3 of the other bottom case.

Four side walls of one bottom shell are not contacted with four side walls of the other bottom shell; and/or the mask column M on one bottom shell is not contacted with the other bottom shell.

As shown in fig. 4, when the two bottom cases are stacked, the sidewalls of the two bottom cases do not contact, and the cover posts of the upper bottom case do not contact the lower bottom case. In the transportation, the friction collision between drain pan and the drain pan only takes place between support piece 2 and locating part 3, goes up the lateral wall all around of drain pan and does not collide with lower drain pan, can effectively protect the drain pan, improves the yield of drain pan, reduces the purchasing cost of drain pan. And the phenomena of deformation, corner collapse, cracking and the like of the mask column M are avoided.

Further, the limiting member 3 is provided with an accommodating hole 301 for accommodating the supporting member 2. Let the bottom of locating part 3 on a drain pan arrange in the accepting hole 301 on another drain pan, when shaking back and forth from side to side, it is more stable, avoid damaging.

Further, a limit block 302 is arranged in the accommodating hole 301; the bottom end of the support member 2 is provided with a limit groove 201 matched with the limit block 302. The limiting block 302 is arranged in the limiting groove 201, and shaking is effectively avoided. The height of the limiting member 3 cannot be large at the time of production. By arranging the limiting blocks 302, when the limiting groove 201 on one bottom shell is matched with the limiting block 302 on the other bottom shell, the distance between the two bottom shells is increased.

Further, the side wall of the limiting block 302 gradually converges inward from bottom to top. The limiting block 302 is conveniently inserted into the limiting groove 201.

Furthermore, the supporting part 2 and the limiting part 3 are uniformly distributed and provided in a plurality. As shown in fig. 1 and 2, the stressed support is more balanced, and the inclination is avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
