CN2426189Y - Character dismountable plug-in type electronic road sign - Google Patents

Abstract

The utility model provides a character dismountable plug-in type electronic road sign which is used for displaying the road directions of buses. Digitals, stereo Chinese characters and patterns composed of stereo pen sections of built-in luminous devices are respectively installed and fixed on a bottom board made of a printed circuit board through position pins and pins. The bottom board is fixed on a bottom frame through a dismountable hinge and a positioning lock buckle to form independent modules for displaying characters. When the characters-the Chinese characters or the patterns or the digitals are required to be changed, so long as the bottom board is demounted, a whole is exchanged into the bottom board of required stereo Chinese characters and patterns or the stereo pen sections are readjusted, inserted and pulled on the bottom board to form new digitals.

Description

Character is detachable, plug-in electronics guideboard

The utility model relates to a kind of improved public transit vehicle electronics guideboard.

Be used to show the electronics guideboard of the other direction in public transit vehicle road at present, its frame mode is: the making to changeless Chinese character (as " air-conditioning ", " XX line ") or pattern (as " * " etc.) shows, adopt Chinese character or pattern modelling on the real estate of electronics guideboard, utilize natural light irradiation daytime, colour contrast by real estate and moulding Chinese character or pattern shows, illuminate moulding Chinese character or pattern then by the luminescent device of substrate back night.And needs are often changed, the numeral of seven sections stroke compositions is made and is shown, then adopts the solid pen section embedding substrate of the plane stroke being made built-in luminescent device, utilizes the substrate junction member, and the pen section can be overturn around its central symmetry axis.When two faces of upset pen section remained on same plane with real estate respectively, whether a section surface color was consistent with real estate, determined this section cancellation or reservation.The numeral that can form needs thus by the seven metal marker sections of overturning arbitrarily.The same with Chinese character or pattern displaying, the digital pen section is utilized natural light irradiation by day, and illuminated by the built-in luminescent device of pen section night.

But the electronics guideboard of above-mentioned form exists because of character (Chinese character, pattern, numeral) is attached on the substrate, makes dismounting transposing difficulty.Digital pen section upset location structure complexity makes digital alter operation inconvenience, and pen section service efficiency is low, and idle pen section is arranged.And adopt during circuit production open-wire line to connect, and Installation and Debugging complexity, reliability reduce, and in addition, character that all will show and substrate are in same plane, thereby character do not have stereoscopic sensation, influence visual effect.

The purpose of this utility model is to provide a kind of improved character detachable, plug-in electronics guideboard, is characterized in simple in structure, and character dismounting transposing is convenient, does not have idle pen section, saves cost.Utilize printed circuit technique, make circuit production simple and reliable, all character that will show Chinese characters of guideboard, pattern and numeral all solid are stood on base plate, thereby visual effect is better.

The utility model is achieved in that numeral that the three-dimensional pen section of built-in luminescent device is formed and solid Chinese character, pattern, by register pin and contact pin, be fixed on respectively on the base plate by print circuit plates making, this base plate then is fixed on the underframe by detachable hinge and location snap close, forms the standalone module of character display.When needs change Chinese character, pattern or numeral, as long as the dismounting base plate, integral body is changed into the base plate of required solid Chinese character, pattern.Perhaps, readjust the three-dimensional pen section of plug on base plate, form new numeral, this kind changed electronics guideboard content way simply, easily and fast, and especially Shuo Zi change can be provided with as required, does not have idle unnecessary pen section, thereby is significantly reduced to this.And the connection of electric wiring is finished by the base plate of print circuit plates making, makes circuit production simple, reliable.In addition, all characters that will show of electronics guideboard, solid is stood on base plate, has obviously improved visual effect.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model bar shaped pen section longitudinal sectional view.

Fig. 2 is the utility model bar shaped pen section front elevation.

Fig. 3 is the cut-open view of Fig. 1 pen section along the A-A line.

Fig. 4 is the detachable base plate scheme of installation of the utility model.

Fig. 5 is the structure cut-open view of the detachable base plate of the utility model along the B-B line.

Fig. 6 is Fig. 4 side sectional view.

Referring to Fig. 1, Fig. 2, [4] are the base plate of print circuit plates making, and [6] are three-dimensional pen section case, and [11] are the register pin of case [6], and [12] are the corresponding pilot hole on the base plate [4], [8] are luminescent device, are welded on the printed circuit board (PCB) [7].[9] go up contact pin for being fixed on circuit board [7], [10] are for being fixed on the socket on the base plate [4].During assembling digital pen section, with circuit board [7] screens in case [6], referring to Fig. 3, the register pin [11] of case [6], the contact pin [9] on the circuit board [7] respectively with base plate [4] on pilot hole [12] and socket [10] carry out machinery and be electrically connected.Use the same method, all the other sections of forming numeral are carried out machinery and are electrically connected with base plate [4] respectively, and the solid Chinese character of built-in luminescent device, pattern are also the same with the assembling of digital pen section, and the register pin that utilizes solid Chinese character, pattern shell and the contact pin that welds LED circuitboard and the pilot hole on the base plate and socket carry out machinery and be electrically connected.Like this, with character one Chinese character, pattern and the numeral that assembles, be assembled into again and have electronics guideboard standalone module detachable, the plug function, referring to Fig. 4, Fig. 5, Fig. 6.[3] be the moulding underframe, [5] are that underframe [3] is gone up snap close, and [1] be detachable hinge, and [2] are fixing Luo Ding.Detachable hinge [1] is separately fixed on underframe [3] and the base plate [4], by detachable hinge [1] and snap close [5], base plate [4] can be positioned on underframe [3] plane, can make base plate [4] break away from snap close [5] effect and unlatching and dismounting again, be convenient to the whole transposing of base plate [4], or the digital pen section on the plug base plate [4], new numeral is formed in layout again.As long as to above-mentioned electronics guideboard character standalone module, displaying contents simply is assembled on the guideboard framework as required, has just finished that character is detachable, the making of plug-in electronics guideboard.

The utility model character is detachable, plug-in electronics guideboard is on probation through entrucking, proves rational in infrastructure, the dependable performance, respond well of this electronics guideboard, and is easy to use, with low cost, is the another trend of electronic bus guideboard development and application.
