[0024] Please continue reading. Figure 5More specifically, in the above-described specific embodiments, the left louver opening limit switch SQ1, the right louver opening limit switch SQ2, and the front louver opening limit switch SQ3 are respectively mounted at the extended positions of the push rods of the left window motor M1, the right window motor M2, and the front window motor M3; the left louver closing limit switch SQ4, the right louver closing limit switch SQ5, and the front louver closing limit switch SQ6 are respectively mounted at the retracted positions of the push rods of the left window motor M1, the right window motor M2, and the front window motor M3. In use, when the push rod of the left window motor M1 extends to the position of the left louver opening limit switch SQ1, the left louver 300 corresponding to the left window motor M1 is fully open, i.e., fully open. When the push rod of the right window motor M2 extends to the position of the right louver opening limit switch SQ2, the right louver 400 corresponding to the right window motor M2 is fully open, i.e., fully open. When the push rod of the front window motor M3 extends to the position of the front louver opening limit switch SQ3, the front louver 500 corresponding to the front window motor M3 is fully open, i.e., fully open. Similarly, when the push rod of the left window motor M1 retracts to the position of the left louver closing limit switch SQ4, the left louver 300 corresponding to the left window motor M1 is in a fully closed state, that is, closed in place; when the push rod of the right window motor M2 retracts to the position of the right louver closing limit switch SQ5, the right louver 400 corresponding to the right window motor M2 is in a fully closed state, that is, closed in place; when the push rod of the front window motor M3 retracts to the position of the front louver closing limit switch SQ6, the front louver 500 corresponding to the front window motor M3 is in a fully closed state, that is, closed in place.

[0025] The working principle of the automatic detection and positioning control system for opening and closing louvers of the low-voltage power supply vehicle provided by this utility model is as follows: In use, the manual / automatic knob S1 for the louvers is used to control the automatic detection and control system for opening and closing the louvers of the entire low-voltage power supply vehicle, selecting manual or automatic mode; the auxiliary contact KA1 for starting the generator set power of the power supply vehicle is used in conjunction with the automatic mode of the manual / automatic knob S1 to control the opening and closing of the louvers; the manual opening / closing knob S2 for the louvers is used in conjunction with the manual mode of the manual / automatic knob S1 to control the opening and closing of the louvers. (i) When the manual / automatic knob S1 of the louver is in automatic mode, the normally open contact of the manual / automatic knob S1 is closed and the normally closed contact is open. At this time, if the generator set of the power supply vehicle starts, the auxiliary contact KA1 of the generator set will conduct synchronously, giving a control signal to open the louver. That is, the normally open contact of the auxiliary contact KA1 of the generator set will close and the normally closed contact will open, the louver opening control circuit will be connected, the coil of the louver opening relay K1 will be energized, and at the same time, the louver... The closing control circuit will disconnect, de-energizing the coil of the louver closing relay K2. Subsequently, the normally open contact of the louver opening relay K1 will close, and the normally closed contact of the louver opening relay K1 will open. The normally open contact of the louver closing relay K2 will open, and the normally closed contact of the louver closing relay K2 will close. Each window motor (e.g., left window motor M1, right window motor M2, and front window motor M3) will rotate forward, opening each louver (e.g., the left / right / front three louvers). After the first three louvers are fully opened, the push rods of each window motor will trigger the opening limit switches of each louver (such as the left louver opening limit switch SQ1, the right louver opening limit switch SQ2, and the front louver opening limit switch SQ3). This causes the normally closed contacts (i.e., the NC terminals) of each louver opening limit switch (such as the left louver opening limit switch SQ1, the right louver opening limit switch SQ2, and the front louver opening limit switch SQ3) to open, thereby de-energizing the coil circuit of the louver opening relay K1. This prevents the louver opening relay from being de-energized. The K1 coil overheats and burns out. If the power supply vehicle generator set is turned off, the power supply vehicle generator set power-on auxiliary contact KA1 will reset, giving a control signal to close the louvers. That is, the normally closed contact of the power supply vehicle generator set power-on auxiliary contact KA1 will close, and the normally open contact of the power supply vehicle generator set power-on auxiliary contact KA1 will open, the louver closing control circuit will be connected, and the louver closing relay K2 coil will be energized. At the same time, the louver opening control circuit will be disconnected, and the louver opening relay K1 coil will be de-energized.Subsequently, the normally open contact of the louver closing relay K2 will close, the normally closed contact of the louver closing relay K2 will open, the normally open contact of the louver opening relay K1 will open, and the normally closed contact of the louver opening relay K1 will close. Each window motor (such as the left window motor M1, the right window motor M2, and the front window motor M3) will reverse, and each louver (such as the left / right / front three louvers) will close. Once each louver (such as the left / right / front three louvers) is closed, each window motor... The push rod will trigger the closing limit switches of each louver (such as the left louver closing limit switch SQ4, the right louver closing limit switch SQ5, and the front louver closing limit switch SQ6), causing the normally closed contacts (i.e., the NC terminals) of the opening limit switches of each louver (such as the left louver closing limit switch SQ4, the right louver closing limit switch SQ5, and the front louver closing limit switch SQ6) to open. This de-energizes the coil circuit of the louver closing relay K2, thus preventing the coil of the louver closing relay K2 from overheating and burning out.

[0026] (II) When the manual / automatic knob S1 of the blinds is in manual mode, the normally closed contact of the manual / automatic knob S1 is closed and the normally open contact is open. At this time, if the manual open / close knob S2 of the blinds is turned counterclockwise, the blinds opening control circuit will be connected, the coil of the blinds opening relay K1 will be energized, and then the normally open contact of the blinds opening relay K1 will close and the normally closed contact of the blinds opening relay K1 will open. The motors of each window (such as the left window motor M1, the right window motor M2, and the front window motor M3) will rotate clockwise, and each blind (such as the left window motor M1, the right window motor M2, and the front window motor M3) will rotate clockwise. The three louvers (left, right, and front) will open. Once each louver (e.g., left, right, and front) is fully open, the push rod of each louver motor will trigger the opening limit switch of each louver (e.g., left louver opening limit switch SQ1, right louver opening limit switch SQ2, and front louver opening limit switch SQ3). This will cause the normally closed contacts (i.e., NC terminals) of each louver opening limit switch (left louver opening limit switch SQ1, right louver opening limit switch SQ2, and front louver opening limit switch SQ3) to open, thereby de-energizing the coil circuit of the louver opening relay K1. This prevents the coil of the blind opening relay K1 from overheating and burning out. If the blind manual opening / closing knob S2 is turned clockwise, the blind closing control circuit will be connected, energizing the coil of the blind closing relay K2. Subsequently, the normally open contact of the blind closing relay K2 will close, and the normally closed contact of the blind closing relay K2 will open. This will cause the motors for each window (such as the left window motor M1, right window motor M2, and front window motor M3) to reverse, closing each louver (such as the left / right / front three louvers). Once the blinds are closed, the push rods of each window motor will trigger the closing limit switches of each blind (such as the left blind closing limit switch SQ4, the right blind closing limit switch SQ5, and the front blind closing limit switch SQ6), causing the normally closed contacts (i.e., the NC terminals) of each blind closing limit switch (such as the left blind closing limit switch SQ4, the right blind closing limit switch SQ5, and the front blind closing limit switch SQ6) to open, thereby de-energizing the coil circuit of the blind closing relay K2. This can prevent the coil of the blind closing relay K2 from overheating and burning out.

[0027] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
