Detailed description of the invention
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, below knotClose embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 to Fig. 4, the invention provides a kind of electric control gear of avoiding excess Temperature to damage, compriseOutside framework 1, is provided with drive motors 2 and controller on outside framework, controller is connected and is used for drive motorsControl drive motors rotates, and on drive motors outer wall, is provided with thermistor, one end ground connection of thermistor,The other end is connected with the voltage acquisition end of controller and one end of divider resistance, the other end of divider resistance withReference voltage connects, and controller suspends the rotation of drive motors when too high for collecting thermistor voltage.As shown in Figure 1, controller control drive motors can adopt the mode of controlling electronic switch, electronic switchCan be relay or transistor etc. In the time that drive motors rotation is smooth, drive motors can generate heat,The resistance of thermistor raises along with temperature rise, and the voltage that thermistor is assigned to uprises, and works as voltageWhile being greater than a setting value, controller can detect, can suspend the driving to drive motors, keeps awayExempt from drive motors work on and cause drive motors damage problem. Drive motors and columniform drivingAxle 3 connects, and driving shaft is flexibly connected with outside framework, and drive motors can drive drive shaft turns. DriveMoving axis is equidistantly provided with multiple driving wheels 4, and as shown in Figure 2, driving wheel inner circular side face is provided with hemisphericalGroove 40, driving shaft is provided with cylinder shape groove 41 at driving wheel place, is provided with spring in cylinder shape groove42, between spring and hemispherical groove, be provided with metal ball 43, the footpath of each driving wheel is upwards provided with biographyMoving plate 5, drive plate is flexibly connected with outside framework, and drive plate can be moving in outside framework transfer. Drive plate with driveDriving wheel vertically arranges, the sidewall of driving wheel and drive plate sidewall contact, and driving wheel is used for being with nutating disk to turnMoving, like this, the axis that driving wheel rotates is just mutually vertical with the pivot center of drive plate. On drive plate, establishBe equipped with first triangular plate 6, the first triangular plate centers coaxial with drive plate and be provided with power transmission shaft 7, power transmission shaftOne end away from the first triangular plate is connected with the center of the second triangular plate 8 and is flexibly connected with outside framework. TheOne triangular plate is parallel with the second triangular plate, and the first triangular plate and the second triangular plate are with respect to the rotation of power transmission shaftAngle is identical. Three limits of such the first triangular plate can form three with three of a second triangular plate limit and put downFace, can be provided with advertisement bar in such three planes. Between the first triangular plate and the second triangular plate, establishBe equipped with advertisement bar (scheming not shown). Advertisement bar is exactly that advertisement complete a view picture is divided into multiple rectanglesStrip, these advertisement bars hang over the edge of triangular plate, multiple advertisement bars have formed again a width advertisement, useAdvertisement can be seen in family, and this face at the advertisement place of seeing can be called advertising display face. Triangular plate hasThree limits, can hang three width advertisements, and three faces that are turn over.
The present invention in use, need to switch advertisement time, only need to switch on drive motors, drive motorsDrive drive shaft turns, the metal ball in driving shaft blocks driving wheel and driving shaft mutually, makes to driveMoving axis can drive driving wheel to rotate. And rear drive sprocket drives drive plate to rotate, drive plate drives aboveThe first triangular plate and power transmission shaft rotate, thereby drive the second triangular plate to rotate, and finally drive advertisement bar to switch.In the time having some triangular plates to block, that triangular plate does not rotate, and can block and be attached theretoDriving wheel. Now will switch advertisement, driving shaft can rotate, and the driving wheel of fault does not rotate,Round metal club in fault driving wheel enters into driving shaft in mutual rotation process, makes to driveAxle is not stuck with fault driving wheel, and fault driving wheel does not affect the rotation of driving shaft, advertisementCan also switch, only the advertisement bar on the triangular plate of fault driving wheel does not change, such one wideAnnouncement bar does not affect the propelling movement of whole advertisement substantially, and client still can turn over above system and obtain extensively from three facesAccuse. Once thereby avoid a triangular plate to damage, the problem that whole system cannot be worked.
In the present invention, driving wheel can be that simple helical teeth is connected with drive plate, then by controlling electricityThe anglec of rotation of machine can realize the switching of triangular plate fixed angle. In certain embodiments, Ke YishiThe drives structure that three faces that background technology is mentioned turn over, as long as driving wheel can be with nutating disk to rotate.
In certain embodiments, in order to realize the rotation of triangular plate fixed angle, as shown in Figure 4, allThree acute angle places of the first triangular plate are all provided with magnet 9, and a side of each the first triangular plate is provided with suddenlyThat sensor 10, Hall element can be arranged on a side of turning over advertising display face back to three faces, and Hall passesSensor is for induced magnet, and Hall element is connected with controller, and controller is used at Hall element quiltWhile enabling, suspend the rotation of drive motors. Be, after controller control drive motors rotates, to turn to magnetWhen the most close Hall element, Hall element is enabled, and now three faces turn over the triangular plate in systemTurn to suitable position, can suspend the rotation of drive motors. Thereby three faces of realizing turn over system spyDetermine the rotation of angle. And motor angle control that need not be special, easily.
On the basis of above-described embodiment, the present invention can also be used for fault and show, also comprises that fault showsEquipment, fault display device is connected with controller, and fault display device is for showing the shape of Hall elementState. Can on fault display device, show the state of Hall element, as turned at normal drive motorsIn moving process, Hall element should be the state of not being enabled, if the state of certain Hall element withOther state is different, is likely that this triangular plate damages to have blocked, and can know the very first timeRoad fault, and the advertising display state that need not turn over by three faces outside checking is known. The present invention uses oneIndividual Hall element is realized angle simultaneously and is detected and fault detect, greatly reduces the complexity of system authority,Simplify the structure, reduced cost, reach good effect simultaneously.
Fault display device of the present invention can be display screen, in certain embodiments, and fault display deviceFor multiple LED lamps, each LED lamp is associated with the detected state of a Hall element. User passes throughCheck which triangular plate damage is the LED situation whether simultaneously amount is gone out can see, cost is low, effective.
While mutually rotation for fear of driving shaft and driving wheel, the feelings of driving wheel transverse shifting on driving shaftCondition, driving shaft is provided with screw hole in the both sides near driving wheel, is provided with protrusion driving shaft in screw holeScrew, screw is used for avoiding driving wheel transverse shifting.
The foregoing is only embodiments of the invention, not thereby limit scope of patent protection of the present invention,Every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do, or directlyOr be indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
