Embodiment Construction

[0011] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0012] see Figure 1 to Figure 4 , the present invention provides an electric control device for avoiding overcurrent damage, comprising an outer frame 1, a drive motor 2 and a controller are arranged on the outer frame, the controller is connected with the drive motor to control the rotation of the drive motor, and the drive motor is connected in series with a detection The voltage acquisition terminal of the controller is connected to the detection resistor, and the controller is used to pause the rotation of the driving motor when the detection resistor voltage is too high. Such as figure 1 As shown, the controller can control the driving motor by controlling an electronic switch, and the electronic switch can be a relay or a transisto...

Abstract

The invention provides an electric control device for avoiding overcurrent damage. The electric control device comprises a driving shaft which is equidistantly provided with multiple driving wheels. The internal circumferential surfaces of the driving wheels are provided with semispherical grooves. The driving shaft is provided with cylindrical grooves at the positions of the driving wheels. The cylindrical grooves are internally provided with springs. A metal circular ball is arranged between each spring and each semispherical groove. A transmission disc is arranged in the radial direction of each driving wheel. The transmission disc is flexibly connected with an external framework. When current is excessively high, rotation of a driving motor can be suspended so that damage to the electric control device can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to an electric control device for avoiding overcurrent damage. Background technique [0002] The existing three-sided turning is widely used in the advertising system, that is, the three-sided rotation of the advertisement is realized under the drive of the motor. The existing technology has the following three-sided turning structure: Patent No.: 201220196151.5, named "A flywheel stepping for three-sided turning billboards The Chinese utility model patent of "double drive system", and the patent number: 201520313082.5, the Chinese utility model patent named "a three-sided billboard driving device and driving wheel". That is to say, the rotation of the horizontal motor becomes the rotation of the vertical triangular plate, while the existing three-sided turning system uses a triangular plate (a driving device) to drive other multiple triangular plates to rotate, thereby rea...
