Description

[0001] The present invention relates to an LED module for an electric vehicle,

The present invention relates to an LED electric signboard, and more particularly, to an LED signboard capable of selectively attaching and detaching an LED module on a front surface or a rear surface without using a separate fixing bulb, And more particularly to an LED module connection structure of a bolt fixed outdoor waterproof type electric signboard.

In general, an LED signboard is a type of advertisement device that displays a variety of characters, designs, animations, and the like by providing a large number of LEDs on the surface of a flat board to control the LED flashing .

Such LED electronic signboards are widely used as indoors and outdoor advertising and publicity media. In particular, the use of outdoor signboards has been increasingly used as a large signboard for a playground, a traffic sign for a road, and an outdoor signboard.

As compared with an output means using a display panel, the LED display has advantages of quick data input / output, visibility of displayed contents, and low maintenance cost. Recently, as shown in Registration Practical Utility Model No. 20-0423828 A portable LED display board has been proposed.

However, in such a conventional LED electric signboard, since the LED module is fixed to the inside of the main body by a plurality of bolts, it is not easy to assemble the LED module, and it is very inconvenient to separate and replace the LED module.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to improve the coupling structure of the LED module and to easily attach and detach the LED module from the front surface or the rear surface without using a separate fixing tool, And an object of the present invention is to provide an LED module coupling structure of a non-bolt fixed outdoor waterproof type electric signboard capable of front and rear detachment which enhances the convenience of replacement.

The present invention relates to an LED module connection structure for a volts-free outdoor waterproof type electric sign board capable of detachable front and rear surfaces, comprising: a plurality of LED modules coupled to a main body; a pinion rotatably coupled to a rear surface of the LED module, And a pair of racks formed at both ends of the pinion are meshed with gears on both sides of the pinion, and the fixing portion is moved laterally by the rotation of the pinion to fix or separate the LED module in the coupling space formed on the front surface of the main body, And a front tool insertion hole and a rear tool insertion hole are formed on the front and rear surfaces, respectively, so that the pinion can be rotated by the front and rear surfaces using a tool.

According to the LED module connection structure of a muffle-fixed outdoor waterproof type electric signboard capable of detachable front and rear faces according to the present invention, a rack and a pinion are operated using a tool on a front surface or a rear surface to easily assemble and detach a plurality of LED modules It is effective.

In addition, since the LED module can be coupled to the main body without using coupling means such as bolts and nuts, which take a long time to assemble and separate the LED module, the replacement of the LED module can be made easier, The time and cost required for management can be saved, which is more economical.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the electric signboard of the present invention is provided with a main body 10, a handle 11 for carrying the main body 10 on the upper side thereof, and a power cord 12 .

A pair of LED modules 100 are detachably coupled to the front surface of the main body 10 and a plurality of front penetration parts 40 are formed on the front surface of the LED module 100.

A front cover 20 is coupled to a front surface of the main body 10 to which the LED module 100 is coupled and a rear cover 30 is coupled to a rear surface of the main body 10.

The front cover 20 and the rear cover 30 are configured to be easy to attach and detach. The front cover 20 protects the LED module 100 when the electric panel moves, 10 for repairing or replacing the parts installed inside.

2, the LED module 100 is detachably coupled to a coupling space 13 formed on a front surface of the main body 10, and the coupling space 13 is formed in a size of the main body 10 And the number of the LED modules 100 can be increased or decreased corresponding to the number of the coupling spaces 13. [

As the power is supplied by the power cord 12, the LED module 100 illuminates a plurality of LEDs provided on the front surface to display various characters, designs, animations and the like. A plurality of insertion holes 14 for fixing the module 100 are formed.

3, a plurality of insertion protrusions 41 are formed on the rear surface of the LED module 100 at positions corresponding to the insertion holes 14 and spaced apart from the insertion protrusions 41 And the packing member 42 is engaged.

2, the insertion protrusions 41 are inserted into the insertion holes 14 to fix the LED module 100 on the front surface of the main body 10. The packing member 42 is inserted into the engagement space 13, Thereby blocking water and dust flowing into the inside of the main body 10.

A rack 60 is coupled to the rear side of the LED module 100 so as to move left and right on the upper and lower sides of the LED module 100. A pair of the racks 60 are coupled to the left and right sides, And a rear penetrating portion 43a is formed at the center of the fixing plate 43. [

A pinion 50 as shown in FIG. 4 is rotatably coupled to a lower side of the fixing plate 43. One end of a rack 60 made of gears is engaged with both sides of the pinion 50, At the other end of the rack 60, a fixing portion 61 to be inserted into a guide 44 formed on the back surface of the LED module 100 is formed.

A rear tool insertion hole 52 is formed in the center of the pinion 50 so as to rotate the pinion 50 by inserting a tool such as a screwdriver or a wrench into the center of the pinion 50, Through-hole penetrating portion 43a.

The LED module 100 having the above-described structure can easily attach and detach the LED module 100 to the engagement space 13 of the main body 10 by rotating the pinion 50 using a tool.

4 (A), when the pinion 50 is rotated in the direction of the arrow (counterclockwise) using a tool, the racks 60 on both sides move outward, 44 projecting outwardly.

5, the fixing portion 61 is fixed to the inner edge portion of the engaging space 13, so that the LED module 100 is simply coupled to the front surface of the main body 10.

When the pinion 50 is rotated in the direction of the arrow (clockwise) as shown in FIG. 4 (B), when the user desires to remove the LED module 100 from the main body 10 in order to replace the LED module 100, The fixing portion 61 is inserted into the guide 44 while moving toward the inside.

The rotation of the pinion 50 is transmitted to the rear surface of the fixing plate 43 while the rear cover 30 is separated from the rear surface of the fixing plate 43. [ Is formed on the rear surface of the main body 10 by inserting the tool into the rear tool insertion hole 52 through the penetrating portion 43a.

6, a front tool insertion hole 51 is formed in the front surface of the pinion 50 so as to communicate with the front penetrating portion 40, The pinion 50 can be rotated also on the front surface of the housing 10.

In this case, since the outside water is permeated through the front penetrating portion 40 and the rear penetrating portion 43a due to the nature of being installed outdoors, the packing ring 53 or the packing ring 53 is formed inside or outside the pinion 50 It is needless to say that the waterproof member of the present invention can be added.

The present invention can be realized by operating a rack 60 and a pinion 50 using a tool so that the LED module 100 can be coupled to the main body 10 without using a coupling means such as a bolt and a nut, 100 can be easily assembled and disassembled, so that replacement of the LED module 100 can be performed more easily, and the time and cost required for maintenance and management of the electric signboard can be reduced, which is more economical.

It is needless to say that the LED module 100 can be applied not only to the portable electric display panel shown in the embodiment of the present invention, but also to the general electric display panel fixed to the building.
