Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 to Fig. 4, this utility model provides a kind of electric control gear avoiding the too high damage of temperature, including outside framework 1, outside framework is provided with drive motor 2 and controller, controller is connected with drive motor and is used for controlling drive motor and rotates, drive motor outer wall is provided with critesistor, one end ground connection of critesistor, the other end is connected with the voltage acquisition end of controller and one end of divider resistance, the other end of divider resistance is connected with reference voltage, controller for collect thermistor voltage too high time suspend drive motor rotation.As it is shown in figure 1, controller controls drive motor can adopt the mode controlling electrical switch, electrical switch can be relay or transistor etc..When drive motor rotates not smooth, drive motor can generate heat, then the resistance of critesistor rises along with temperature and raises, the voltage that then critesistor is assigned to uprises, when voltage is more than a setting value, controller can detect, namely can suspend the driving to drive motor, it is to avoid the problem that drive motor works on and causes drive motor to damage.Drive motor is connected with cylindrical driving axle 3, drives axle to be flexibly connected with outside framework, and namely drive motor can drive drive shaft turns.Axle is driven to be placed equidistant multiple driving wheel 4, as shown in Figure 2, driving wheel inner circular side face is provided with hemispherical groove 40, drive axle that driving wheel place is provided with cylinder shape groove 41, be provided with spring 42 in cylinder shape groove, between spring and hemispherical groove, be provided with metal ball 43, each driving wheel be radially provided with drive plate 5, drive plate is flexibly connected with outside framework, and drive plate can move in outside framework transfer.Drive plate and driving wheel are vertically arranged, the sidewall of driving wheel and drive plate sidewall contact, and driving wheel rotates for band nutating disk, and so, the axis that driving wheel rotates just is mutually perpendicular to the pivot center of drive plate.Being provided with first triangular plate 6 coaxial with drive plate on drive plate, the first triangular plate is provided centrally with power transmission shaft 7, and power transmission shaft is connected away from one end of the first triangular plate with the center of the second triangular plate 8 and is flexibly connected with outside framework.First triangular plate is parallel with the second triangular plate, and the first triangular plate and the second triangular plate are identical relative to the anglec of rotation of power transmission shaft.Three limits of such first triangular plate can constitute three planes with the three of the second triangular plate limit, and such three planes can be provided with advertisement bar.Namely advertisement bar (not shown go out) it is provided with between the first triangular plate and the second triangular plate.Advertisement bar is exactly that advertisement complete for a view picture is divided into multiple rectangular strip, these advertisement bars hang over the edge of triangular plate, multiple advertisement bars constitute again a width advertisement, and user is it can be seen that advertisement, it is seen that this face at advertisement place be properly termed as advertising display face.Triangular plate has three limits, it is possible to hang three width advertisements, and three faces that are are turned over.
This utility model is in use, it is necessary to during switching advertisement, it is only necessary to be energized by drive motor, drive motor drives drive shaft turns, drives the metal ball in axle by driving wheel and to drive axle mutually to block to drive axle that driving wheel can be driven to rotate.And rear drive sprocket drives drive plate to rotate, drive plate drives the first triangular plate above and drive axis, thus driving the second triangular plate to rotate, finally drives advertisement bar switching.In time having some triangular plate to block, then that triangular plate does not rotate, and can block the driving wheel being attached thereto.Now to switch advertisement, axle is then driven to rotate, and the driving wheel of fault does not rotate, then the round metal club in fault driving wheel enters in driving axle in mutual rotation process, make to drive axle not to be stuck with fault driving wheel, then fault driving wheel has no effect on the rotation driving axle, then advertisement can also switch, only the advertisement bar on the triangular plate of fault driving wheel does not change, such advertisement bar has substantially no effect on the propelling movement of whole advertisement, and namely client still can turn over acquisition advertisement above system from three faces.Thus avoiding once there be individual triangular plate to damage, the problem that whole system cannot work.
In this utility model, driving wheel can be that simple helical teeth is connected with drive plate, then namely can realize the switching of triangular plate fixed angle by controlling the anglec of rotation of motor.In some embodiments it is possible to be the driving structures turned over of three faces that background technology is mentioned, as long as driving wheel energy band nutating disk rotates.
In certain embodiments, in order to realize the rotation of triangular plate fixed angle, as shown in Figure 4, three acute angle places of all first triangular plates are both provided with Magnet 9, and the side of each first triangular plate is both provided with Hall element 10, and Hall element can be arranged on the side turning over advertising display face back to three faces, Hall element is used for induced magnet, Hall element is connected with controller, and controller is for when Hall element is enabled, suspending the rotation of drive motor.Namely after controller controls drive motor rotation, when turning to Magnet near Hall element, Hall element is enabled, and now three faces are turned over the triangular plate in system and had been pivoted into suitable position, it is possible to suspend the rotation of drive motor.Thus the rotation of system special angle is turned in three faces that realize.Control without special motor angle, it is convenient to.
On the basis of above-described embodiment, this utility model can be also used for malfunction coefficient, also includes malfunction coefficient equipment, and malfunction coefficient equipment is connected with controller, and malfunction coefficient equipment is for showing the state of Hall element.The state of Hall element can be shown on malfunction coefficient equipment, as in normal drive motor rotation process, Hall element should be the state that is not enabled, if the state of certain Hall element is different with other state, then it is likely to the damage of this triangular plate be seized, then the very first time can know fault, without by checking that the advertising display state that three faces, outside are turned over is known.This utility model uses a Hall element to realize angle detection and fault detect simultaneously, greatly reduces the complexity of system authority, simplifies structure, reduce cost, reaches good effect simultaneously.
Malfunction coefficient equipment of the present utility model can be display screen, and in certain embodiments, malfunction coefficient equipment is multiple LED, the detection state relation of each LED and a Hall element.The situation that then whether user goes out by checking LED to measure simultaneously is namely it can be seen which triangular plate damages, and cost is low, effective.
During in order to avoid driving axle and driving wheel mutually to rotate, the situation of driving wheel transverse shifting on the driving shaft, drive axle that the both sides near driving wheel are provided with screw hole, be provided with in screw hole and protrude the screw driving axle, screw is used for avoiding driving wheel transverse shifting.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
