Further, in order to provide gear hand feeling and jerking feeling when shifting gears, as shown in fig. 1, in this embodiment, the annular flange 22 is uniformly provided with the concave portions 23 matching with the convex portions 51 along the circumference thereof, the convex portions 51 are abutted against the surface of the annular flange 22 through local elastic deformation of the pressing plate 5, after the housing 2 rotates by a certain angle, the convex portions 51 are embedded into the concave portions 23, the local elastic deformation of the pressing plate 5 is released, and a gear hand feeling is provided at the same time, at this time, the third conductor 43 and the fourth conductor 44 are respectively in conduction connection with two ends of a certain resistor 331 so as to realize gear connection; when the housing 2 continues to rotate and the convex portion 51 is rotated out of the concave portion 23, the pressing plate 5 is forced to generate local elastic deformation, so as to provide another gear feeling, and the third conductor 43 and the fourth conductor 44 are disconnected from two ends of a certain resistor 331 respectively. Therefore, through the cooperation of the convex part 51 and the concave part 23, different gear hand feels and setback feelings are provided for the rotary adjusting switch for the solar sighting telescope during gear switching, and the gear switching is more accurate.

Such a connection facilitates the mounting and replacement of the rotary circuit board 3.

In addition, as shown in fig. 1, a projection 25 is provided on the boss 24, and the rotating circuit board 3 is provided with a groove 34 matching with the projection 25, and when the rotating circuit board 3 is mounted on the boss 24, the projection 25 is embedded in the groove 34, so that the rotating circuit board 3 can be driven by the projection 25 to rotate together when the housing 2 rotates.

In order to further stabilize the second battery 94 and meet the requirements of dust-proof and water-proof, as shown in fig. 2, in this embodiment, the rotary regulating switch for the solar sighting telescope further includes a top cover 7, the top cover 7 is detachably connected (e.g., screwed or snapped) with the housing 2, and an insulating pad 71 for pressing the second battery 94 is disposed on a side of the top cover 7 facing the battery compartment 21. In this embodiment, the top cover 7 is connected to the housing 2 by a screw, and when the top cover 7 is screwed to the housing 2, the insulating pad 71 is pressed against the second battery 94, so that the second battery 94 is pressed against the fixed circuit board 4, which is beneficial for the negative electrode of the second battery 94 to be in close contact with the negative copper foil 36, thereby ensuring the reliability of the electrical connection, and further stabilizing the second battery 94 to prevent the second battery 94 from loosening.

In order to meet the switching requirement of the sighting device for the double power supplies and save the control power consumption, as shown in figure 14, in this embodiment, the rotary adjusting switch for the solar sighting device further includes a power selection module 8, the power selection module 8 is provided with a first power input terminal 81, a second power input terminal 82, a power output terminal 83, a first voltage-controlled switch 84 and a second voltage-controlled switch 85, the first power input terminal 81 and the second power input terminal 82 are respectively connected to the power output terminal 83 through the first voltage-controlled switch 84 and the second voltage-controlled switch 85, and the first voltage-controlled switch 84 and the second voltage-controlled switch 85 are electronic switches that control the switches to be turned on or off by using voltage as a control parameter, either the first power input 81 or the second power input 82 is electrically connected to the first conductor 41, either the third conductor 43 or the fourth conductor 44 is electrically connected to the power output terminal 83.

Specifically, both the first power input terminal 81 and the second power input terminal 82 can be used to access the solar cell 93 or the second battery 94, and the solar cell 93 and the second battery 94 are used in cooperation. In this embodiment, the first power input terminal 81 is connected to the solar battery 93, the second power input terminal 82 is connected to the second battery 94, and the first voltage-controlled switch 84 and the second voltage-controlled switch 85 are connected in parallel and then connected to the power output terminal 83, so that both the voltage of the first power input terminal 81 and the voltage of the second power input terminal 82 can control the on or off of the first voltage-controlled switch 84 and the second voltage-controlled switch 85, and this control is represented as: when the voltage of the first power input terminal 81 is greater than the voltage of the second power input terminal 82, the first voltage-controlled switch 84 is turned on to turn on the first power input terminal 81 and the power output terminal 83 so as to output the electric quantity of the solar battery 93, and the second voltage-controlled switch 85 is turned off so as to cut off the output channel of the second battery 94 and retain the electric quantity of the second battery 94; when the voltage of the first power input 81 is less than the voltage of the second power input 82, the first voltage-controlled switch 84 is turned off, and the second voltage-controlled switch 85 is turned on, so that the second power input 82 and the power output 83 are turned on to ensure the power supply capacity of the circuit, for example, the power requirement of the light emitter. When the voltage of the solar cell 93 is equal to the voltage of the second battery 94, the selection mode of the power selection module 8 may be preset as required, so that the power selection module 8 selects the solar cell 93 and the second battery 94 to supply power together or selects the solar cell 93 to supply power alone. In the present embodiment, when the voltage of the solar cell 93 is equal to the voltage of the second battery 94, the solar cell 93 is selected to supply power alone. In this way, the first voltage-controlled switch 84 and the second voltage-controlled switch 85 are combined to form a logic switch controlled by voltage, so that a power supply with higher voltage can be automatically selected for supplying power without consuming extra control power consumption, and the purpose of saving power quantity of the power supply is achieved.

Therefore, the power selection module 8 does not need to consume extra control power consumption in the process of selecting the power supply, but utilizes the voltage information of the two power supplies to perform automatic comparison, and compared with the prior art that the gear is controlled by using a processing chip MCU, the automatic selection mode can save the control power consumption, thereby effectively prolonging the service life and the endurance time of the second battery 94, simplifying the circuit structure and reducing the cost of a control circuit.

Since the voltage of the solar cell 93 changes with the change of the ambient light intensity, in order to enable the solar cell 93 to provide a stable and reliable power supply, as shown in fig. 6 to 12, in this embodiment, the power supply selection module 8 further includes a voltage stabilizing circuit 80, and the voltage stabilizing circuit 80 is connected to the power supply output end 83. It should be noted that the constant voltage circuit 80 can stably output a constant voltage as long as the voltage input to the constant voltage circuit 80 meets the requirement of the constant voltage circuit 80, for example, as long as the input voltage of the constant voltage circuit 80 is greater than or equal to 2.7V, the constant voltage circuit 80 can stably output a 2.5V voltage, otherwise, the constant voltage circuit 80 cannot output any voltage.

The power selection module 8 may have the following structure:

the first power supply selection module structure: as shown in fig. 6, the first voltage-controlled switch 84 and the second voltage-controlled switch 85 in the power selection module 8 are a first PMOS transistor 86 and a second PMOS transistor 87, the first power input terminal 81 and the second power input terminal 82 are connected to the input terminal of the first PMOS transistor 86 and the input terminal of the second PMOS transistor 87, the output terminal of the first PMOS transistor 86 and the output terminal of the second PMOS transistor 87 are connected to the power output terminal 83, the control terminal of the first PMOS transistor 86 is connected to the second power input terminal 82, and the control terminal of the second PMOS transistor 87 is connected to the first power input terminal 81. It should be noted that the first PMOS transistor 86 and the second PMOS transistor 87 are both P-channel fets, and each of the P-channel fets has a source, a drain, and a gate, wherein the source or the drain can be selected as an input terminal or an output terminal of the P-channel fet, and when one of the sources is the input terminal, the other one is the output terminal, and the gate is used as a control terminal of the P-channel fet for providing a comparison potential, that is, the P-channel fets control the on or off of the source and the drain through a potential difference between the gate and the source, where it should be noted that the potential difference between the gate and the source refers to a voltage value displayed when an anode and a cathode of the voltmeter are respectively connected to the gate and the source, and is represented by Ugs. For example, when the potential difference between the gate and the source is less than the threshold voltage of the P-channel field effect transistor, the source and the drain are conducted; when the potential difference between the grid and the source is larger than or equal to the threshold voltage of the P-channel field effect transistor, the source and the drain are cut off.

Specifically, as shown in fig. 6, the first power input terminal 81 and the second power input terminal 82 are respectively connected to the source of the first PMOS transistor 86 and the source of the second PMOS transistor 87, the drain of the first PMOS transistor 86 and the drain of the second PMOS transistor 87 are both connected to the power output terminal 83, the gate of the first PMOS transistor 86 is connected to the second power input terminal 82, and the gate of the second PMOS transistor 87 is connected to the first power input terminal 81. As can be seen from the connection scheme shown in fig. 6, the Ugs of the first PMOS transistor 86 refers to the potential difference between the second power input terminal 82 and the first power input terminal 81, and the Ugs of the second PMOS transistor 87 refers to the potential difference between the first power input terminal 81 and the second power input terminal 82. Therefore, when the difference between the potential of the second power input terminal 82 and the potential of the first power input terminal 81 is less than or equal to the threshold voltage of the first PMOS transistor 86, the first PMOS transistor 86 is turned on or off; when the difference between the potential of the first power input terminal 81 and the potential of the second power input terminal 82 is less than or equal to the threshold voltage of the second PMOS transistor 87, the second PMOS transistor 87 is turned on or off. Thus, a logic switch circuit for selecting one power supply to be turned on or off by comparing the voltage between the two power supplies is formed, and the power supply with higher voltage is selected as the power supply of the power utilization circuit.

In order to fully utilize the electric quantity of the solar energy, so that the solar cell 93 still supplies power when the voltage of the solar cell 93 is equal to the voltage of the second cell 94, in this embodiment, the first power input end 81 is connected to the solar cell 93, the second power input end 82 is connected to the second cell 94, the threshold voltage of the second PMOS transistor 87 is zero, the threshold voltage of the first PMOS transistor 86 is greater than the threshold voltage of the second PMOS transistor 87, when the voltage of the first power input end 81 is equal to the voltage of the second power input end 82, both the Ugs of the first PMOS transistor 86 and the Ugs of the second PMOS transistor 87 are zero, the first PMOS transistor 86 is turned on, and the second PMOS transistor 87 is turned off, so that the first power input end 81 is turned on with the power output end 83 to output the electric quantity of the solar cell 93, and the electric quantity of the second cell 94 is reserved.

In this embodiment, the micro-switch further includes a voltage stabilizing circuit 80, and the power output end 83 is disposed at the input end of the voltage stabilizing circuit 80, so that the voltage output by the power selection module 8 can be stabilized by accessing the external circuit after passing through the voltage stabilizing circuit 80 regardless of the voltage output by the first power input end 81 or the voltage output by the second power input end 82, which is beneficial to providing a stable and non-fluctuating voltage signal for the micro-switch in the circuit with the micro-switch, and the micro-switch can be operated more precisely.

The second power supply selection module structure: as shown in fig. 7, the difference from the first power selection module structure is that the first PMOS transistor 86 and the second PMOS transistor 87 both have parasitic diodes, the first power input terminal 81 and the second power input terminal 82 are respectively connected to the drain of the first PMOS transistor 86 and the drain of the second PMOS transistor 87, and the source of the first PMOS transistor 86 and the source of the second PMOS transistor 87 are connected in parallel to the power output terminal 83. Like the first power selection module, the gate of the first PMOS transistor 86 is connected to the second power input 82, and the gate of the second PMOS transistor 87 is connected to the first power input 81. As can be seen from the connection scheme shown in fig. 7, the Ugs of the first PMOS transistor 86 is the potential difference between the second power input terminal 82 and the power output terminal 83, and the Ugs of the second PMOS transistor 87 is the potential difference between the first power input terminal 81 and the power output terminal 83. When both the solar cell 93 and the second cell 94 are connected to the power selection module 8, since the potential of the power output terminal 83 is zero, the Ugs of the first PMOS transistor 86 is equal to the voltage to ground of the second power input terminal 82 and is much larger than the threshold voltage thereof, and the Ugs of the second PMOS transistor 87 is equal to the voltage to ground of the first power input terminal 81 and is much larger than the threshold voltage thereof, both the first PMOS transistor 86 and the second PMOS transistor 87 are in the off state. At this time, current may flow to the power output terminal 83 through the parasitic diode of the first PMOS transistor 86 or the parasitic diode of the second PMOS transistor 87, for example, when the voltage of the first power input terminal 81 is greater than the voltage of the second power input terminal 82, the parasitic diode of the first PMOS transistor 86 is in a forward bias state, and the parasitic diode of the second PMOS transistor 87 is in a reverse bias state, and current can only flow to the power output terminal 83 through the parasitic diode of the first PMOS transistor 86; when the voltage of the first power input terminal 81 is lower than the voltage of the second power input terminal 82, the parasitic diode of the first PMOS transistor 86 is in a reverse bias state, and the parasitic diode of the second PMOS transistor 87 is in a forward bias state, so that the current can only flow to the power output terminal 83 through the parasitic diode of the second PMOS transistor 87; when the voltage of the first power input terminal 81 is equal to the voltage of the second power input terminal 82, the parasitic diode of the first PMOS transistor 86 is forward biased, the parasitic diode of the second PMOS transistor 87 is also forward biased, and the current can flow to the power output terminal 83 through the parasitic diode of the first PMOS transistor 86 and the parasitic diode of the second PMOS transistor 87 at the same time.

When the potential of the first power input terminal 81 is lower than the potential of the second power input terminal 82, the second PMOS transistor 87 is turned on, and at this time, the first unidirectional diode 88 is in a reverse bias state, and current can only flow to the power output terminal 83 through the second PMOS transistor 87; when the potential of the first power input terminal 81 is greater than the potential of the second power input terminal 82, the second PMOS transistor 87 is turned off, and at this time, the first unidirectional diode 88 is forward biased, and current can only flow to the power output terminal 83 through the first unidirectional diode 88; when the potential of the first power input end 81 is equal to the potential of the second power input end 82 and the threshold voltage of the second PMOS transistor 87 is greater than zero, the second PMOS transistor 87 is turned on, and the voltages of the positive and negative terminals of the first unidirectional diode 88 are equal to zero at this time, which does not meet the requirement of voltage drop of diode conduction, so that the first unidirectional diode 88 is turned off, and current can only flow to the power output end 83 through the second PMOS transistor 87; when the potential of the first power input terminal 81 is equal to the potential of the second power input terminal 82 and the threshold voltage of the second PMOS transistor 87 is equal to zero, the second PMOS transistor 87 is turned off, and at this time, the first unidirectional diode 88 is forward biased, and current can only flow to the power output terminal 83 through the first unidirectional diode 88.

Fourth power selection modular architecture: as shown in fig. 9, the difference from the third power selection module structure is that the second PMOS transistor 87 is replaced by a second unidirectional diode 89, the second power input terminal 82 is disposed at the anode of the second unidirectional diode 89, and the cathode of the second unidirectional diode 89 and the cathode of the first unidirectional diode 88 are both connected to the power output terminal 83. When the potential of the first power input terminal 81 is lower than the potential of the second power input terminal 82, the second unidirectional diode 89 is in a forward bias state, and at this time, the first unidirectional diode 88 is in a reverse bias state, and current can only flow to the power output terminal 83 through the second unidirectional diode 89; when the potential of the first power input terminal 81 is greater than the potential of the second power input terminal 82, the second unidirectional diode 89 is in a reverse bias state, and at this time, the first unidirectional diode 88 is in a forward bias state, and current can only flow to the power output terminal 83 through the first unidirectional diode 88; when the potential of the first power input terminal 81 is equal to the potential of the second power input terminal 82, the second unidirectional diode 89 and the first unidirectional diode 88 are both in a forward bias state, and a current can flow to the power output terminal 83 through the first unidirectional diode 88 and the second unidirectional diode 89 at the same time.

A fifth power selection module configuration: as shown in fig. 10, the difference from the first power selection module structure is that a power output terminal 83 is provided at an output terminal of a regulator circuit 80, an output terminal of a first PMOS transistor 86 is connected to the power output terminal 83 through the regulator circuit 80, a first power input terminal 81 is used for connecting a positive electrode of a solar battery 93, and a second power input terminal 82 is used for connecting a positive electrode of a second battery 94. Thus, when the first PMOS transistor 86 is turned on, the voltage with the fluctuation characteristic output by the solar cell 93, which is susceptible to the influence of ambient light, becomes a stable voltage after passing through the voltage stabilizing circuit 80 and is provided to the external circuit, and the second cell 94 has the characteristic of stable output voltage, so that when the second cell 94 supplies power, the stable voltage can be directly output without passing through the voltage stabilizing circuit 80 and provided to the external circuit, the voltage drop caused by the second cell 94 after passing through the voltage stabilizing circuit 80 can be eliminated, and the service life and the endurance time of the second cell 94 can be prolonged.

Thus, when the second PMOS transistor 87 is turned on, the voltage with the fluctuation characteristic output by the solar cell 93, which is susceptible to the influence of ambient light, becomes a stable voltage after passing through the voltage stabilizing circuit 80 and is provided to the external circuit, and the second cell 94 has the characteristic of stable output voltage, so that when the second cell 94 supplies power, the stable voltage can be directly output without passing through the voltage stabilizing circuit 80 and provided to the external circuit, the voltage drop caused by the second cell 94 passing through the voltage stabilizing circuit 80 can be eliminated, and the service life and the endurance time of the second cell 94 can be prolonged.

Seventh power selection modular configuration: as shown in fig. 12, the difference from the third power selection module structure is that the power output end 83 is disposed at the output end of the voltage regulator circuit 80, the output end of the second PMOS transistor 87 is connected to the power output end 83, the first power input end 81 is connected to the power output end 83 after passing through the voltage regulator circuit 80 and the first unidirectional diode 88 in sequence, the cathode of the first unidirectional diode 88 faces the power output end 83, the second power input end 82 is used for connecting the anode of the second battery 94, and the first power input end 81 is used for connecting the anode of the solar battery 93. Thus, as long as the voltage of the solar cell 93 is greater than the voltage of the second cell 94, when the second PMOS transistor 87 is turned off, the voltage with fluctuation characteristics output by the solar cell 93, which is susceptible to the influence of ambient light, becomes a stable voltage after passing through the voltage stabilizing circuit 80 and is provided to the external circuit, and the second cell 94 itself has the characteristic of stable output voltage, when the second cell 94 supplies power, the stable voltage can be directly output without passing through the voltage stabilizing circuit 80 and provided to the external circuit, so that the voltage drop caused by the second cell 94 passing through the voltage stabilizing circuit 80 can be eliminated, which is beneficial to prolonging the service life and the endurance time of the second cell 94.
