Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

The utility model relates to a portable LED display screen which is convenient to carry and very convenient to assemble and install.

FIG. 1 shows a front side view of a portable LED display screen of the present invention. In this figure, one of the LED display modules 2 is detached from the base plate 1 in order to show the structure of the base plate 1.

As shown in fig. 1, the portable LED display screen of the present invention includes a base plate 1 and a plurality of LED display modules 2 mounted on the base plate 1. And the LED display modules 2 are arranged on the bottom plate 1 and jointly spliced into an LED display screen.

In contrast to the commonly used rigid base plates, in the present invention the base plate 1 is a flexible base plate that is deformable. In this way, the base plate 1 can be deformed during transport or the like, for example, by rolling the base plate 1 into a roll or into a laminated structure. Thereby making it more portable.

In the present invention, the base plate 1 may be made of a deformable material, and the specific type of the deformable material is not limited.

FIG. 4 shows a rear view of the base plate of the portable LED display screen of the present invention after installation. As shown in fig. 4, in the present invention, a plurality of support rods 7 are provided at the rear of the base plate 1. The flexible base plate 1 is supported by the plurality of support rods 7 to prevent it from deforming during use.

Preferably, the rear of the base plate 1 is provided with a plurality of sockets 8. Both ends of the support rod 7 are respectively inserted into one of the sockets 8. Therefore, when the LED display screen is assembled and disassembled, the supporting rod 7 can be inserted and pulled out very conveniently, and the LED display screen can be assembled and disassembled very conveniently.

Still preferably, the plurality of support bars 7 includes a lateral support bar and a longitudinal support bar. In this way, the bottom plate 1 can be supported both laterally and longitudinally, making the bottom plate 1 more resistant to deformation after assembly.

As shown in fig. 1 and 2, in the present invention, a plurality of grooves 3 are formed on the base plate 1, and a layer of magnet is embedded in each groove 3.

Meanwhile, as shown in fig. 3, the back of each of the LED display modules 2 is provided with a protrusion 5. The projection 5 is made of a metal material. An attractive force may be generated between the metal material and the magnet. The protrusion 5 corresponds to the shape of the recess 3, i.e. the protrusion 5 can be inserted into the recess 3. Thus, when the LED display module 2 is mounted on the base plate 1, the protrusion 5 is drawn into the groove 3 by magnetic force, so that the LED display module 2 can be mounted and fixed on the base plate 1.

Preferably, the back of each LED display module 2 is provided with two protrusions 5. And, two grooves 3 are arranged on each area of the bottom plate 1 where the LED display screen 2 is installed. Therefore, each LED display module 2 can be installed on the bottom plate 1 through the matching of the two protrusions 5 and the two grooves 3, and the installation and the fixation of the LED display module 2 are firmer.

In the present invention, as shown in fig. 1 to 3, preferably, a plurality of rectangular magnetic stripe frames 4 are further disposed on the bottom plate 1. The length and width of the magnetic stripe frame 4 are similar to those of the LED display module 2. Moreover, a rectangular metal frame 6 is arranged on the back of each LED display module 2.

In this way, when the LED display module 2 is mounted on the base plate 1, the magnetic stripe bezel 4 and the metal bezel 6 cooperate to more securely mount and fix the LED display module 2 on the base plate 1 by the suction force therebetween.

Therefore, in the utility model, the whole LED display screen is formed by assembling a plurality of LED display modules, and the bottom plate adopts the deformable flexible bottom plate, so that the LED display screen is particularly convenient to transport after being disassembled, and is very convenient to carry.

Further, although not shown in the drawings, the base plate 1 is further provided with a plurality of perforations. In this way, the power line and the signal line of each LED display module 2 can pass through one of the through holes, thereby facilitating the power supply to the LED display module 2 and the control of the LED display module 2 to emit light.

Fig. 5 shows a schematic cross-sectional view of an LED display module of the portable LED display screen of the present invention to illustrate the construction of the LED display module. As shown in fig. 5, in the present invention, the LED display module 2 includes a housing 9 and a cover plate 10 coupled to the housing 9. The housing 9 is matched with the cover plate 10 to form a sealed cavity, so that the dustproof and waterproof effects can be achieved, and the service life of the LED display module 2 can be prolonged.

A printed circuit board 11 is provided in the housing 9. And the printed circuit board 11 is provided with a plurality of LED lamp beads 12. The housing 9 is made of a transparent material. Therefore, the light emitted by the LED lamp beads 12 can be transmitted through the outer shell 9.

Preferably, the housing 9 is made of transparent plastic or transparent acryl material. In this way, the LED display module 2 is made lighter in weight, so that the LED display module 2 can be more firmly fitted and fixed to the chassis 1.

The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. Obvious changes and modifications of the technical scheme of the utility model are included in the protection scope of the utility model.
