[0022] The method for switching between internal and external batteries includes the main assembly 1, control module 2, screen module 3, internal battery pack 4, and external battery pack 5. The battery switching steps are as follows: (1) Power on, control module 2 obtains the power of internal battery pack 4 and external battery pack 5, and screen module 3 displays the power of internal battery pack 4 and external battery pack 5 in real time; (2) The control module 2 determines the remaining power of the inner battery pack 4 and the outer battery pack 5 respectively, and prioritizes the use of the outer battery pack 5; (3) When the external battery pack 5 is in a low voltage state, the power supply is automatically switched to the internal battery pack 4, and the external battery pack 5 is replaced or removed to realize the external charging of the external battery pack 5. (4) When the external battery pack 5 is installed, the power supply will be automatically switched to the external battery pack 5.

[0023] The aforementioned method of switching between internal and external batteries, through the cooperation of the internal battery pack 4 and the external battery pack 5, improves the power supply stability of the scope during use, enabling the scope to have multiple power supply modes and reducing the risk of power shortage. At the same time, with the help of the screen module 3, the user can clearly see the power levels of the internal battery pack 4 and the external battery pack 5 in real time, facilitating the switching between the two and effectively reducing the situation where insufficient power affects the use of the scope, thus making the use of the scope easier.

[0024] The screen module 3 has a first display area and a second display area, which are arranged in an arc shape. The first display area is used to display the power level of the inner battery pack 4, and the second display area is used to display the power level of the outer battery pack 5. The user can clearly see the power levels of the inner battery pack 4 and the outer battery pack 5 in real time, which facilitates the switching between the inner battery pack 4 and the outer battery pack 5, and effectively reduces the situation where insufficient power affects the use of the scope, thus facilitating the use of the scope.

[0025] The first display area and the second display area are arranged along the edge of the screen module 3, respectively; in this way, the first display area and the second display area are avoided from affecting the image presentation of the screen module 3.

[0026] The internal and external battery switching method includes a switching circuit. When the voltage of the internal battery pack 4 is lower than a preset value, the screen module 3 displays a low battery warning, reminding the user to install the external battery pack 5. When the external battery pack 5 is installed, the switching circuit automatically switches to the external battery pack 5 for power supply. When the internal battery pack 4 is working normally, the switching circuit automatically switches to the external battery pack 5 for power supply when the external battery pack 5 is installed.

[0027] When the external battery pack 5 operates at a low voltage, the system will display a low external circuit warning, and the switching circuit will automatically switch to the internal battery pack 4 for power supply. When the external battery pack 5 is operating, it can be replaced at any time, and the switching circuit will automatically switch back to the internal battery pack 4 for battery life or power supply.

[0028] In this way, the switching between the external battery pack 5 and the internal battery pack 4 can be achieved without power interruption, which facilitates the use of the scope.

[0029] When the internal battery pack 4 and the external battery pack 5 are assembled and powered synchronously, the external battery pack 5 takes priority in power supply. When the external battery pack 5 is low in power, the internal battery pack 4 provides power or extends the battery life.

[0030] The sight with switchable internal and external batteries includes a main assembly 1, a control module 2, a screen module 3, an internal battery pack 4, and an external battery pack 5. The main assembly 1 includes a main barrel component. The control module 2, screen module 3, internal battery pack 4, and external battery pack 5 are respectively assembled to the main barrel component. The internal battery pack 4 includes an inner protective sleeve 41, an internal battery component, and an inner connecting piece. The inner protective sleeve 41 is installed inside the main barrel component, and the internal battery component is installed inside the inner protective sleeve 41. The inner end of the inner connecting piece is connected to the internal battery component. The inner connecting piece is arranged in a non-conductive manner, with the inner connecting piece penetrating the inner casing 41 and the outer end of the inner connecting piece being connected to the control module 2. The outer battery pack 5 includes an outer casing 51 and an outer battery component. The outer casing 51 is installed inside the main casing, and the outer battery component is installed inside the outer casing 51. The outer battery component is connected to the control module 2. The outer casing 51 is located between the inner casing 41 and the control module 2. The inner connecting piece is arranged flexibly, and the inner connecting piece and the outer surface of the outer casing 51 are arranged in an overlapping manner.

[0031] The aforementioned internal and external battery switching scope, through the cooperation of the internal battery pack 4 and the external battery pack 5, improves the power supply stability of the scope during use, enabling the scope to have multiple power supply modes and reducing the risk of power shortage. At the same time, with the help of the screen module 3, the user can clearly see the power levels of the internal battery pack 4 and the external battery pack 5 in real time, which facilitates the switching between the internal battery pack 4 and the external battery pack 5 and effectively reduces the situation where insufficient power affects the use of the scope, thus making the scope easier to use.

[0032] The external battery pack 5 includes a positive electrode module 53 and a negative electrode module 52. The two ends of the outer casing 51 are respectively assembled with the positive electrode module 53 and the negative electrode module 52.

When the negative pressure cover 521 is in the closed state, it applies pressure to the negative cap pressure member. The negative pressure cover 521 has a cover fixing head. The cover fixing head is fixed or separated from the cover pressure block 522. The cover pressure block 522 is connected to the cover spring. The cover spring is used to make the cover pressure block 522 in the fixed state. When the cover pressure block 522 is subjected to external force to overcome the elastic force of the cover spring, it is made to separate.

[0034] By opening the negative pressure cover 521, the external battery can be removed for charging or placed in for use. By closing the negative pressure cover 521, the external battery is protected. That is, the cooperation between the negative pressure cover 521 and the negative pressure cap ensures the power supply to the external battery. At the same time, the cooperation between the cover fixing head and the cover pressing block 522 facilitates the opening or closing of the negative pressure cover 521.

[0035] The control module 2 includes a main control board 21, a battery control board 22, and a heat sink 23. The battery control board 22, the main control board 21, and the heat sink 23 are arranged in sequence. The fasteners pass through the battery control board 22 and the main control board 21 and are screwed onto the heat sink 23. The battery control board 22 and the main control board 21 are respectively arranged in correspondence with the outer casing 51. The heat sink 23 includes a heat sink plate and multiple heat sink blocks 232. Each heat sink block 232 is assembled with the heat sink plate and is integrally formed. The heat sink blocks 232 are protruding in the direction toward the main control board 21. The main control board 21 has a chip part 211. The heat sink blocks 232 and the chip part 211 are arranged facing each other.

[0036] This effectively utilizes space, facilitates the layout of the main control board 21 and the battery control board 22, and helps improve the assembly stability of the control module 2. At the same time, under the action of the heat sink 23, heat accumulation is reduced and the service life of the heat sink 23 is improved.

[0037] The heat dissipation plate includes a longitudinal plate segment 231. The ends of the main control board 21 and the battery control board 22 are respectively arranged correspondingly to the longitudinal plate segment 231. The longitudinal plate segment 231 has two fixed plate parts and two plate fixing seats, which are arranged in a one-to-one correspondence. The fixing members pass through the fixed plate parts and are screwed to the plate fixing seats. The fixed plate parts are stacked with the battery control board 22 to improve the stability of the battery control board 22. The main control board 21 is stacked with the plate fixing seats, and the plate fixing seats provide support and fixation for the main control board 21, thereby improving the stability of the main control board 21.

[0038] The main cylinder has a clamping plate part, which is arranged in a ring shape and has a clamping plate groove. The longitudinal plate segment 231 is embedded in the clamping plate groove to position the heat dissipation plate and improve the stability of the heat dissipation plate, thereby improving the stability of the main control board 21 and the battery control board 22.

[0039] The longitudinal plate segment 231 has a segment opening, and the main cylinder has a fixed plate strip. The fixed plate strip is arranged in a protruding manner and is embedded in the segment opening to realize the positioning and reinforcement of the heat dissipation plate.

[0040] The main cylinder includes a housing section and a mounting section, which are connected and aligned. The diameter of the mounting section gradually increases in the direction away from the housing section. The main control board 21 and the battery control board 22 are located in the housing section. The mounting section has a retaining plate to position the heat sink and improve the stability of the heat sink, thereby improving the stability of the main control board 21 and the battery control board 22.

[0041] The internal and external battery switching sight includes a magnification module 6, which includes a magnification adapter 61, a magnification auxiliary block 62, a magnification fixing component 63, and a dew-proof bracket 64. The magnification adapter 61 is used to magnify the field of view. The magnification adapter 61 and the dew-proof bracket 64 are respectively installed on the main tube. The magnification adapter 61 and the magnification auxiliary block 62 are movably assembled. The magnification fixing component 63 and the magnification auxiliary block 62 are fixed or movable along the vertical direction. The dew-proof bracket 64 has a bracket opening, which corresponds to and communicates with the interior of the inner tube 41. The magnification adapter 61 is electrically connected to the internal battery component through the bracket opening.

[0042] In this way, the position of the amplifier adapter 61 can be adjusted as needed to adjust the amplification level and meet various usage requirements. At the same time, the bracket facilitates wiring, thereby facilitating the power supply of the internal battery to the amplifier module 6.

[0043] The screen module 3 includes a screen body 31, a screen heat sink 34, a screen PCB board 32, and a screen mounting frame 33. The screen body 31, the screen heat sink 34, and the screen PCB board 32 are arranged sequentially and at intervals. The screen body 31 and the screen heat sink are arranged in an overlapping and contacting manner. The screen body 31 and the screen PCB board 32 are connected and conductive through a flexible board. The screen body 31 and the screen heat sink are respectively installed on the screen mounting frame 33. A screen mounting hole is formed in the middle of the screen mounting frame 33. The display surface of the screen body 31 is arranged corresponding to the screen mounting hole. The screen mounting frame 33 has multiple support columns. The screen mounting rods pass through the screen PCB board 32 and are movably assembled with the support columns.

[0044] In this way, the heat dissipation component 34 reduces the heat accumulation on the screen PCB board 32 and improves the service life of the screen PCB board 32; at the same time, the screen mounting bracket 33 improves the stability of the screen body 31 and facilitates the centered arrangement of the screen body 31.

[0045] The inner casing 41 includes a casing and a casing plate. The inner end of the casing is fixedly arranged, and the outer end of the casing is connected to the casing plate. The casing plate and the main casing are assembled or disassembled. The casing has multiple shell fixing strips that extend along the axial direction.

The battery body and the fixed radio station are assembled, and the fixed radio station is protruding in a direction away from the battery body. The casing has a battery placement groove and a casing fixing groove, which are connected. The battery body is embedded in the battery placement groove, and the fixed radio station is embedded in the casing fixing groove.

[0046] The combined action of the various shell fixing strips and cylinder fixing grooves enhances the assembly stability of the inner casing 41 and the main cylinder, and also restricts and reinforces the inner casing 41, preventing shaking from affecting the assembly stability between the inner casing 41 and the main cylinder. At the same time, through the cooperation of the battery placement groove and the chamber fixing groove, the assembly of the inner battery component is realized, as well as the limiting of the inner battery component, preventing the inner battery component from rotating or shifting, improving the assembly stability of the inner battery component, and ensuring the normal power supply of the inner battery component. In this way, the assembly stability of the inner battery component and the inner casing 41 is greatly increased, ensuring the use of the scope.

[0047] The battery body is arranged in a cylindrical shape, the radio station has a trapezoidal cross-section, and the radio station and the outer surface of the battery body are stacked and assembled; the battery compartment has a circular cross-section, and the battery compartment has a trapezoidal cross-section.

[0048] In this way, the battery compartment facilitates the assembly of the battery body, the stationary slot facilitates the assembly of the stationary radio, and the stationary slot restricts the stationary radio, thereby limiting the rotation or displacement of the battery body and improving the assembly stability of the battery body.

[0049] The compartment plate has a middle plate groove and a side plate groove, which are arranged in a connected manner. Along the axial direction, the middle plate groove corresponds to and is connected to the battery placement groove, and the side plate groove corresponds to and is connected to the compartment positioning groove. The battery body is simultaneously embedded in the middle plate groove and the battery placement groove, and the positioning station is simultaneously embedded in the side plate groove and the compartment positioning groove. In this way, the compartment plate avoids affecting the removal and assembly of the internal battery components, and facilitates the assembly of the internal battery components.

[0050] The main cylinder component includes a main cylinder shell and a limiting shell. The main cylinder shell and the limiting shell are arranged in a butt joint and integrally formed. The diameter of the limiting shell is larger than the diameter of the main cylinder shell. The silo shell is placed inside the main cylinder shell, and the silo plate is placed in the limiting shell. The silo plate and the end of the main cylinder shell are arranged in abutment.

[0051] In this way, when the inner casing 41 is assembled with the main casing, the bin plate plays a positioning role, which facilitates the assembly of the inner casing 41 with the main casing. At the same time, it enhances the positioning effect of the inner casing 41 and improves the assembly stability of the inner casing 41.

[0052] The inner wall of the silo shell is arranged in contact with the outer surface of the silo plate; in this way, it plays a role in limiting the position and restricting the displacement of the silo plate, further enhancing the assembly stability of the inner protective cylinder 41.

[0053] The compartment shell is equipped with a compartment block, which is arranged in an arc shape. The compartment plate has a fixed plate groove, and the compartment block is located in the fixed plate groove. The compartment block is used to restrict the relative rotation of the compartment plate. Under the action of the compartment block, the relative rotation between the inner battery component and the main cylinder component is restricted, thereby improving the assembly stability of the inner casing 41.
