Fig. 3 is illustrated in the structure of the combination coupling member 24 that connects two adjacent blocks.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, the combined method of module of the present utility model is described.
The power in the module of the present utility model and the fixed component 6,8 of fixed component in the transmission case body 1,7 and driven supporting box adopt the combined type aluminium section bar that T type mounting groove is arranged on vertical at least one direction.Because this aluminium section bar has various finished product not need special production for selecting for use, so can reduce production costs, also has advantages such as antirust, that deadweight is low simultaneously.Utilize the T type groove on the combined aluminium alloy profile, can easily the display device module be installed on any stent-type matrix that play supporting role, can utilize T type bolt 20 attaching nuts that sink in the T type groove or employing to sink to specialized nut fitted bolt in the T type groove during installation, just can be fixed on support 10 or play on the installation matrix of support effect.Utilize this T type groove can carry out to each other combination very easily simultaneously.Combination can be adopted and utilize combined member and without two kinds of methods of combined member: when without combined member, the same type assembly end of required number display device module can be connected and the installation method during respectively with independent the use has been fixed on the support or matrix of fixed bearing effect, the machinery of just having finished the display device intermodule makes up.When adopting this array mode, support or matrix play the combination coupling member.Certainly, utilize combination coupling member shown in Figure 3, elongated T type combined member is placed the type of the T separately groove at port joint place, and fix with assembly separately with bolt respectively and reach the purpose that combination connects.Better method is to select the combined aluminium alloy profile that T type groove is all arranged on three directions for use, and the T type groove on all the other both directions brings convenience power and transmission component and driven bearing assembly when assembly and adjustment.And the combination between display module can utilize this combined type aluminium section bar to carry out.At first select the aluminium alloy extrusions of required number of modules multiple length.Promptly select the triple-length aluminium section bar as three module combinations, the power and the dynamically supported plate that then each are equipped with motor and driving-chain member are fixed on the corresponding supporting member successively.But constitute power and the transmission component and the driven bearing assembly of corresponding three times of width: these assemblies and triangular prism are linked, be fixed on support or the matrix, just finish the intermodule combination as support.But because power and transmission component and driven bearing assembly belong to precision components, therefore, this mode only limits in the preceding use of dispatching from the factory.
In the utility model device in the power and transmission case body of each module, two its centers of triangular prism of design outermost end on the driving-chain direction are half of two adjacent triangular prism centre distance in the driving-chain to the distance of each ultromotivity and transmission component and driven bearing assembly end, power and transmission case body and driven supporting box two ends have higher flatness and smooth finish, make the same item assembly two ends of display module to dock well and reach the purpose of combination.Its connection place two triangular prism centre distance of combination back are identical.This its driving-chain of combination mechanically is toward each other independently.Each module power and transmission are independently of one another, do not exist to connect between each module driving-chain and the driving error accumulation, and driving error is controlled in each module.
For feature capable of being combined on the cooperative mechanical structure and independence each other, in the module of each display device, be provided with separately position detecting device and controller.Have this property independently of one another and characteristic capable of being combined from physical construction to the control system just because of the display device module, make this display device module both can independently use, but also large-area display device of combination with one another or double-side display device.During independent the use, with the display device module that assembles by power and transmission component and driven bearing assembly on rack-mount or any matrix that plays fixation, and the combination between power and transmission component and driven bearing assembly end envelope advertisement module also can be connected the corresponding power of each display device intermodule and transmission component and driven bearing assembly end and be installed on the common support or on the matrix of any fixation, and, just finish the intermodule combination with outermost end power and transmission component and the sealing of driven bearing assembly end.Certainly also can adopt combination coupling member 24 to make connection to each other make up more reliable.
The thickness of the double-faced advertising board that the utility model is formed is less and can not influence attractive in appearance.The power of the present utility model and the kind of drive adopt the direct current torque motor of flat directly to drive the mode of driving-chain.
From power shown in Fig. 4 and transmission synoptic diagram,, therefore do not need reduction gear, and good control characteristic and the bigger characteristics of output torque are arranged owing to the direct current generator that adopts under the state that may operate at the low speed large torque.Owing to there is not reduction gear, power and transmission component volume are reduced, and, the moment of inertia of the load on the motor rotary shaft under same load, converted, only the reduction gear ratio when reduction gear is arranged square/one, thereby make whole display device have good control characteristic.Reduce requirement simultaneously to motor load power starting moment.The kind of drive of power and transmission component adopts gear drive, and driving-chain adds the identical idle pulley of a physical dimension 52 of the coaxial gears that links of all and triangular prism.The effect of this feelings wheel is each other interference when making all triangular prisms prevent to overturn along same direction upset.For the driving-chain driving error is reduced as much as possible, and direct current torque motor is installed in the middle part of driving-chain, makes its maximum driving error accumulation be reduced to 1/3rd of whole transmission chain error accumulation.Certainly, implement this patent and also can adopt other types motor and driving-chain.Adopt the mode of common electric machine acceleration and deceleration device, necessary installation site and the space that increases speed reduction unit, between of the requirement of aforementioned advertisement module characteristic capable of being combined to structure, its motor and speed reduction unit can only be placed on the back of driving-chain, this structure can increase the thickness and the volume of power and transmission component, seem heavy when making other purposes of open air, inconvenience is installed.Thickness when being combined into double-side display device seems bigger.Thereby not recommended employing.Its kind of drive also can adopt the mode of sheave driven gear as shown in the figure.
Fig. 5 illustrates the another kind of implementation of display module of the present utility model, in the figure: 4 is motor, 19 is the sheave dial of installing with motor coaxle, 18 is 3 groove sheaves, 2 are and the coaxial mounted gear of sheave, it is 1: 1 transmission gear driving-chain that this gear drives ratio of gear by idle pulley 5, and drives the triangular prism upset.
Fig. 6 illustrates the another kind of implementation of display module of the present utility model, and in the figure: 4 is torque motor, directly drives the sheave dial of installing with motor coaxle 21, and this dial is stirred 6 groove sheaves 22, and sheave dial 21 whenever circles, and 6 groove sheaves turn over 60 degree.Drive the triangular prism upset by driving 1: 1 gear transmission chain that follow-up gear 2 and idle pulley 5 form with 1: 2 ratio of gear with sheave 22 coaxial mounted gears 23.This kind mode three-flute sheave structure motion more shown in Figure 6 is steady, but its shortcoming is that this can increase the thickness and the volume of power and transmission component undoubtedly owing to increase one-level gear drive in 1: 2 thereby increased corresponding physical dimension, does not therefore recommend to use.These the two kinds transmission scheme common advantage with Geneva mechanism are to reduce the control accuracy requirement of controller to motor.Common drawback is the physical dimension that increases driving-chain, makes power and the bigger trend of transmission component volume.
Fig. 7 illustrates modularization variable picture display device modular structure cut-open view of the present utility model.For improving the control accuracy of total system, adopt rotary encoder as position detecting device, rotary encoder accurately and timely offers controller with the positional information and the velocity information of triangular prism, forms a high-precision closed-loop control system.Consider that always there is this factor in error,, and rotary encoder is installed in motor and the middle part between triangular prism farthest for the influence with driving error reduces as far as possible.It is 1/4th of whole driving-chain transmission accumulation that this mode cooperates the mid-direct driving of motor to make the departure of display device module.
Be the design of fit structure patrix blocking, make whole display device to control, all have property independently of one another and characteristic capable of being combined from physical construction.Independently on the controller combination interconnecting interface is being set separately.Exchange information by this interconnecting interface, make the display device control section after the combination form an organic whole, reach each combined display equipment intermodule strict synchronism.Do not connect same mode setting by each controller and can reach synchronous purpose though do not add the mutual interface of combination, owing to lack to each other information transmission, thereby lack globality, its reliability also can reduce because of the increase of composite module number.In addition, the method that adopts a controller to control all motors can reach the purpose of combined advertisements module controls to a certain extent.But having only the display device that rotary encoder is housed is closed-loop control system.To all the other display device modules are open loop control mode, and this mode can not be fed back and be corrected the error of all generations, thereby poor reliability and can not using.The installation of controller and fixed form, the design philosophy of cooperation integral moduleization is installed on it in driven bearing assembly, forms driven supporting and Control Component.For this reason, whole display device is modular construction, very is convenient to combination of transportation and user installation and working service.
The utility model is also taked other measure except that adopting modular design: as the triangular prism of picture carrier adopt have again can be antirust than high specific strength the whole extrusion profile of aluminium alloy.Similarly power and transmission support plate and driven support plate also can select for use aluminium alloy as material, and its transmission component as gear, can be a material with nylon or polyoxymethylene together with bolster also, adopt the technology of injection molded to come processing in enormous quantities.
As shown in Figure 7,9 pictures that are shown for triangular prism or word content are on its prismatic surface, and 4 is the flat direct current torque motor.In order to make driving error on the driving-chain reduce to minimum, therefore motor is placed the central authorities of driving-chain, make driving error be reduced to half of whole driving-chain length cumulative errors.This motor stator partly is fixed on power and the transmission support plate 6, when odd number is prismatic, this rotor part links to each other with prismatic 9 with gear 2, when even number is prismatic, link with a gear, wherein the gear 5 that does not directly link with triangular prism is as idle pulley, and its effect is the reverses direction that changes triangular prism, make all triangular prism Equidirectional overturnings, interfere mutually in case go up when overturning.6 and 8 is power and transmission support plate.With the gear shaft of power and running part, thereon by Bearing Installation.All the other gears except that idle pulley link by its outrigger shaft and triangular prism, to drive the triangular prism upset, link at the triangular prism other end and driven bearing assembly outrigger shaft, reach the effect of pivoting support.Driven support plate 11 and 13 is fixed on the driven supporting member 12,17, constitutes driven supporting box, and the rotary encoder 16 and the controller 15 of detection effect has been installed in driven casing, and rotary encoder and controller constitute a closed loop position control system.For making the minimum that influences that driving error accumulation causes, and with its be installed in motor with at a distance of the middle part of driving-chain between triangular prism farthest, like this, with the accumulation of driving error reduce to that whole transmission chain error accumulates 1/4th.Under similar circumstances, improve nearly four times of transmission accuracy.Below just constituted the display device module, this module can be installed on the support that play supporting role or other any matrixes that play supporting and installation effect on, as buildings, wall etc. are just can use separately.This display device module can be used as the billboard around the stadiums.
Fig. 8 illustrates the combined situation of intermodule in the display device of the present utility model.With the display device module power and the transmission component of requirement, driven bearing assembly respective end is joined, and the T type groove by separately is installed in support or any other is installed on the body again, has just finished combination mechanically.Perhaps utilize microscler T type combined member 24 to place in the T type groove of two display device modules, fix with nut 25 and display device module separately respectively again, and reach the effect that combination connects.In addition, other modes that can also utilize T type groove to provide are carried out the connection combination of display device intermodule.Because the display device module has the interconnected characteristic of both direction, mechanical drive train is independently of one another in addition, and therefore combination can not produce cumulative errors.In the control corresponding system to the interconnected relative measures of also having taked.Therefore, the number of its combination and area are restricted hardly.
Fig. 9 illustrates vertical implementation of combinations thereof.
