Abstract

A practice sign adopting an LED dynamic mode comprises a practice sign and a shell for mounting the practice sign; the practice sign comprises a rectangular PCB, the front surface of the PCB comprises a display module consisting of LED lamps, and the rear surface of the PCB comprises a control module; the PCB is arranged on the front surface of the shell, the front surface of the PCB is positioned outside the shell, and the rear surface of the PCB is positioned inside the shell; the back of the shell is also provided with a switch button and a battery socket; the control module is connected with the battery socket through the switch button to supply power and drives the display module to flicker and display; the practice sign is changed into the lighting display combining the LED lamps into the 'practice' two characters, so that the practice sign can be displayed in a luminous mode at night, the LED lamps can generate a flickering effect through the control module, and finally the display pattern combined by the LED lamps is inserted randomly, so that the display effect of the practice sign is further highlighted.

Description

Practice sign adopting LED dynamic mode

Technical Field

The utility model belongs to the technical field of the mark at car rear and specifically relates to an adopt practice mark of LED active mode.

Background

With the development of technology, the prior need of hiring car drivers to drive cars is changed into the prior need of driving almost every adult, so that many school bus industries are gradually developed, at present, in the process of driving adults and a period of time after driving adults, due to technical unskilled, for the sake of safety, practice marks need to be attached to the rear of the cars to remind drivers passing behind the practice cars to avoid as much as possible, but the existing marks mostly adopt sticker marks, and the light is dark under the night condition, so that the drivers passing behind the practice cars cannot be driven, and the marks fail at night.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.

A practice sign adopting an LED dynamic mode comprises a practice sign and a shell for mounting the practice sign; the practice sign comprises a rectangular PCB, the front surface of the PCB comprises a display module consisting of LED lamps, and the rear surface of the PCB comprises a control module; the PCB is arranged on the front surface of the shell, the front surface of the PCB is positioned outside the shell, and the rear surface of the PCB is positioned inside the shell; the back of the shell is also provided with a switch button and a battery socket; the control module is connected with the battery socket through the switch button to supply power and drives the display module to flicker and display.

Furthermore, the display module also comprises a pattern module and a character module; the pattern module is positioned in the upper area of the front surface of the PCB, and the pattern module is arranged and combined into the shape of any pattern through the LED lamps; the character module is located in the lower area of the front surface of the PCB, and the character module is combined into a character in a 'practice' shape through the arrangement of the LED lamps.

Furthermore, the front surface of the PCB is covered with a transparent silica gel diaphragm.

Furthermore, four inserting through holes are respectively formed in four corners of the shell, and plastic vacuum chucks are respectively embedded in the inserting through holes.

Further, the control module is a 51-chip microcomputer with the model number of 'AT 89C 51'.

Compared with the prior art, the beneficial effects of the utility model are that: the practice sign is changed into the lighting display combining the LED lamps into the 'practice' two characters, so that the practice sign can be displayed in a luminous mode at night, the LED lamps can generate a flickering effect through the control module, and finally the display pattern combined by the LED lamps is inserted randomly, so that the display effect of the practice sign is further highlighted.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, in an embodiment of the present invention, a practice sign using an LED dynamic manner includes a practice sign and a housing 11 for mounting the practice sign; the practice sign comprises a rectangular PCB (printed circuit board) 10, the front surface of the PCB 10 comprises a display module 12 consisting of LED lamps, and the rear surface of the PCB 10 comprises a control module 15; the PCB 10 is arranged on the front surface of the shell 11, the front surface of the PCB 10 is positioned outside the shell 11, and the rear surface of the PCB 10 is positioned inside the shell 11; the back of the shell 11 is also provided with a switch button 13 and a battery socket 14; the control module 15 is connected with the battery socket 14 through the switch button 13 for supplying power to drive the display module 12 to carry out flicker display; the LED lamp display module is used for displaying, the control module 15 controls the LED lamp to flicker, and the unobvious effect of the existing sticker mark is replaced.

As further shown in fig. 1, the display module 12 further includes a pattern module 122 and a text module 121; the pattern module 122 is located at the upper region of the front surface of the PCB board 10, and the pattern module 122 is arranged and combined into a shape of any pattern by the LED lamp; the character module 121 is located in the lower region of the front surface of the PCB 10, and the character module 121 is combined into a character of a "practice" shape by means of the arrangement of LED lamps; the LED lamps are arranged and combined into the shape of two characters for practice and the shape of any pattern, so that the display effect of the practice mark is further enhanced.

As further shown in fig. 1, the front surface of the PCB 10 is covered with a transparent silicone membrane to prevent electric shock accidents.
