Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1 and 4, the utility model discloses a very simple diode and travel switch control position circuit, including diode D1, diode D2, travel switch S1, stroke light S2, actuating mechanism 1, first power source V1, second power source V2, detect position movable block 2 and move between travel switch S1 and stroke light S2, detect position movable block 2 and be connected with actuating mechanism 1, travel switch S2 'S one end is connected respectively to first power source V1, diode D2' S negative pole, travel switch S2 'S the other end is connected respectively to diode D2' S positive pole, travel switch S1 'S one end, diode D1' S positive pole, travel switch S1 'S the other end is connected respectively to diode D1' S negative pole, actuating mechanism 1 'S one end, actuating mechanism 1' S the other end inserts second power source V2. The actuator 1 is an electric motor or a motor.
As shown in fig. 1, at this time, the power source can be connected between the first power source interface V1 and the second power source interface V2, and the actuator 1 drives the detection position moving block 2 to move to the travel switch S1 or the travel switch S2. For example, at this time, the first power interface V1 is connected to the positive power supply, the second power interface V2 is connected to the negative power supply, and at this time, the detection position moves toward the travel switch S2. When the actuator is operated to the position of the travel switch S2, the travel switch S2 is actuated to switch to COM to NO, as shown in fig. 2, and the diode D2 is present, so that the actuator 1 is unpowered.
In fig. 2, if the first power interface V1 is connected to a negative power supply and the second power interface V2 is connected to a positive power supply, the current flows through the actuator 1, the travel switch S1, and the diode D2, and the detection position moving block 2 moves toward the travel switch S1. When the vehicle moves to a position away from the travel switch S2, the travel switch S2 acts to switch COM (common end) to be connected with NC (normally closed), and then the vehicle returns to the initial state. At this time, if the power supply mode is continuously maintained, the detection position moving block 2 continues to run towards the travel switch S1 until the travel switch S1 is operated, and at this time, the travel switch S1 operates to switch to COM to be connected with NO (normally open), as shown in fig. 3.
In fig. 3, at this time, because the diode D1 exists, current cannot pass through the travel switch S1 and the diode D1, so that the actuator 1 cannot obtain a complete power supply and is no longer operated. At this time, only the polarities of the power supplies of the first power supply interface V1 and the second power supply interface V2 can be switched, and the operation of the actuator 1 to the position of the travel switch S2 is changed.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
