Description

Technical Field

[0001] This invention relates to the field of optical device technology, and more particularly to an observation device. Background Technology

[0002] Handheld observation devices such as telescopes and imagers are widely used in outdoor reconnaissance, security detection, and field operations. Currently, these devices integrate infrared and white light dual-paths to meet observation and aiming needs under different lighting conditions. However, the dual-path design increases the overall power consumption of the device. Existing observation devices often use a single battery module for power, resulting in short battery life. Furthermore, battery replacement causes the device to shut down due to power loss, requiring the user to restart it afterward, thus impacting the user experience. Summary of the Invention

[0003] In view of this, the present invention provides an observation device to solve the problems of short battery life and power outage caused by battery replacement in existing dual-optical-path observation devices.

[0004] This application provides an observation device, comprising: The lens barrel assembly has a first mounting slot and a second mounting slot inside; An optical system is mounted on the lens barrel assembly; and A first battery assembly and a second battery assembly, the first battery assembly including a first battery detachably mounted in a first mounting slot, the second battery assembly including a second battery detachably mounted in a second mounting slot, the optical system being electrically connected to the first battery and the second battery.

[0005] The observation device provided in this embodiment of the invention includes a first battery assembly and a second battery assembly on the telescope tube assembly. Both the first battery of the first battery assembly and the second battery of the second battery assembly are electrically connected to the optical system. Therefore, both the first and second batteries can power the optical system, improving the battery life of the observation device. Furthermore, since both the first and second batteries are removable, users can replace them themselves. When replacing one of the first or second batteries, the other can still power the optical system, allowing the observation device to replace batteries without interrupting power.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0029] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0030] Example a Please see Figures 1 to 4 An observation device 1, such as a sight, telescope, or thermal imager, is provided in this embodiment of the invention. The observation device 1 includes a telescope tube assembly 10, an optical system 12, and a battery module 14. The optical system 12 and the battery module 14 are respectively mounted on the telescope tube assembly 10. The telescope tube assembly 10 has a mounting groove, and the battery module 14 is installed in the mounting groove. The battery module 14 is electrically connected to the optical system 12 to supply power to the optical system 12. The optical system 12 is used to receive external light signals and form an image.

[0031] To ensure extended battery life, the battery module 14 includes a first battery assembly 16 and a second battery assembly 18. The lens barrel assembly 10 has a first mounting slot 20 and a second mounting slot 22 for mounting the first battery assembly 16 and the second battery assembly 18, respectively. Both the first battery assembly 16 and the second battery assembly 18 are electrically connected to the optical system 12, so both battery assemblies can supply power to the optical system 12, forming a dual-battery power supply mode, which increases the overall total power and helps extend the battery life of the observation device 1.

[0032] To further facilitate easy assembly and disassembly, the first battery assembly 16 includes a first battery 24 detachably installed in the first mounting slot 20, and the second battery assembly 18 includes a second battery 26 detachably installed in the second mounting slot 22. Both the first battery 24 and the second battery 26 are electrically connected to the optical system 12, and the observation device 1 can power the optical system 12 either through both the first battery 24 and the second battery 26, or solely through one of them. This dual-battery power supply mode increases the total power capacity of the observation device 1, helping to extend its runtime. Furthermore, both the first battery 24 and the second battery 26 are removable, allowing the user to replace the damaged or low-power batteries themselves. When replacing one of the first battery 24 or the second battery 26, the other can still power the optical system 12, enabling the observation device 1 to replace batteries without interrupting power and preventing downtime caused by battery replacement.

[0033] It should be noted that the first battery 24 is detachably installed in the first mounting slot 20, and the second battery 26 is detachably installed in the second mounting slot 22. This means that the first battery 24 can be removed from the first mounting slot 20, and the second battery 26 can be removed from the second mounting slot 22. The specific method of removing the first battery 24 and the second battery 26 is not limited. It can be that the first battery 24 and the second battery 26 are removed individually, or the first battery assembly 16 and the second battery assembly 18 are removed from the lens barrel assembly 10 as a whole, thereby indirectly allowing the first battery 24 and the second battery 26 to exit from the first mounting slot 20 and the second mounting slot 22. In other words, when replacing the batteries, it is possible to choose to replace either the first battery 24 or the second battery 26 individually, or to choose to replace either the first battery assembly 16 or the second battery assembly 18.

[0034] It should be noted that the observation device 1 can power the optical system 12 either through the combined operation of the first battery 24 and the second battery 26, or solely through one of the two batteries. Specifically, the optical system 12 can be electrically connected to the first battery 24 and the second battery 26 via two independent connection circuits. That is, the optical system 12 is electrically connected to the first battery 24 through one connection circuit and to the second battery 26 through another connection circuit. This forms two electrical loops. When both loops are closed, the first battery 24 and the second battery 26 jointly power the optical system 12. When one loop is closed and the other is open, the closed battery powers the optical system 12 independently. Alternatively, the first battery 24 and the second battery 26 can be connected in parallel and then electrically connected to the optical system 12. In an optional example, the first battery assembly 16 and the second battery assembly 18 are connected in parallel, that is, the first battery 24 and the second battery 26 are connected in parallel. The optical system 12 is electrically connected in the loop after being connected in parallel with the first battery 24 and the second battery 26, so that the first battery 24 and the second battery 26 can both supply power to the optical system 12 together or supply power to the optical system 12 individually. When the power of one battery is insufficient, the other battery can automatically supplement the power supply, so as to achieve the effect of power complementarity.

[0035] The number and capacity of the first battery 24 and the second battery 26 can be the same or different. In an optional example, the first battery 24 is a single cell, and the second battery 26 is multiple cells, such as two cells. The total capacity of the second battery assembly 18 is greater than that of the first battery assembly 16. Specifically, the first battery 24 is of the 18500 specification with a capacity of 2400mAh; the second battery 26 is of the 18650 specification, and there are two cells, each with a capacity of 3850mAh. The two second batteries 26 are connected in series, and the total capacity of the second battery assembly 18 is 7700mAh. The total capacity of the observation device 1 is 10100mAh, which can fully meet the power consumption requirements of the observation device 1 and improve the battery life.

[0036] In one embodiment, the observation device 1 further includes a flexible protective sleeve 28, which covers the outer side of the telescope assembly 10. The flexible protective sleeve 28 is relatively soft, and when the user holds the observation device 1 in their hand, their hand comes into contact with the flexible protective sleeve 28. The softness of the flexible protective sleeve 28 can improve the user's grip.

[0037] Optionally, the flexible protective case 28 is made of soft rubber modified PVC (Polyvinyl Chloride). Soft rubber modified PVC is a polymer material obtained by adding specific modifiers (such as plasticizers) to further improve the performance of soft PVC. Soft rubber modified PVC not only has excellent weather resistance, making it less prone to aging and yellowing during long-term outdoor use, and adaptable to complex environments such as high and low temperatures and humidity; it also has a good feel and texture, moderate softness, and strong anti-slip properties, which can improve the comfort of holding it for a long time; at the same time, it has good molding processability, can be adapted to the complex shape and inverted structure of the observation equipment 1, without the need for forced demolding, reducing production difficulty and cost.

[0038] The soft rubber modified PVC material can be coated onto the outside of the lens barrel assembly 10 by injection molding. The coating thickness is uniform and it fits tightly with the shell to avoid loosening or lifting.

[0039] The telescope tube assembly 10 is made of metal or alloy, possessing high strength and rigidity. This prevents deviations in the optical axis direction of the optical system 12 due to deformation of the telescope tube assembly 10 after assembly, ensuring assembly accuracy. Furthermore, the good thermal conductivity of metals or alloys allows for timely dissipation of heat from the telescope tube, preventing overheating from affecting the optical system 12. In an optional example, the telescope tube assembly 10 is made of magnesium alloy. Magnesium alloy has a relatively low density, reducing the overall weight of the observation device 1 while maintaining the assembly accuracy of the optical system 12, making it easier to handle and carry.

[0040] In one embodiment, the observation device 1 includes a lens barrel assembly 10, an optical system 12, and a battery module 14. The optical system 12 and the battery module 14 are respectively mounted on the lens barrel assembly 10, and the battery module 14 is electrically connected to the optical system 12. The lens barrel assembly 10 is made of high-strength and high-rigidity metal or alloy components, such as magnesium alloy. The outer side of the lens barrel assembly 10 is covered with a soft, flexible protective sleeve 28, such as soft rubber modified PVC. When the observation device 1 is a binocular observation device, the magnesium alloy lens barrel assembly 10 can ensure the consistency of the optical axes of the two optical systems 12. The softness and anti-slip properties of the soft rubber modified PVC material improve the grip, thereby solving the problem of the contradiction between multi-optical axis consistency and grip feel.

[0041] Please see Figure 1 , Figure 3 as well as Figure 5 In one embodiment, a flexible protective sleeve 28 covers the first battery assembly 16, making the first battery assembly 16 a built-in battery assembly. At least a portion of the flexible protective sleeve 28 is movable relative to the telescope assembly 10 to expose the outer end of the first battery assembly 16, facilitating the replacement of the first battery 24. When the first battery 24 does not need to be replaced, the flexible protective sleeve 28 covers the first battery assembly 16, making the first battery 24 a built-in battery with a relatively low replacement frequency, only requiring replacement when the first battery 24 is damaged or its performance degrades. When replacement is required, the flexible protective sleeve 28 can be moved relative to the telescope assembly 10 to expose the first battery assembly 16, thus facilitating the replacement of the first battery 24. The first battery 24 satisfies the regulatory requirement for a removable built-in battery while also preventing the first battery assembly 16 from being exposed and affecting the aesthetics of the observation device 1 by covering it with the flexible protective sleeve 28.

[0042] Understandably, the movement of the flexible protective sleeve 28 relative to the lens barrel assembly 10 can be achieved by deformation, sliding, or rotating. When the first battery assembly 16 is exposed, the movement can be achieved by the entire flexible protective sleeve 28 relative to the lens barrel assembly 10, or by a local area of ​​the flexible protective sleeve 28 corresponding to the first battery assembly 16 relative to the lens barrel assembly 10.

[0043] In an alternative example, the flexible protective sleeve 28 moves relative to the lens barrel assembly 10 by deformation, thereby covering or exposing the first battery assembly 16. Since the flexible protective sleeve 28 is relatively soft and can undergo elastic deformation, the flexible protective sleeve 28 can be pried up from its edge and then lifted to expose the covered first battery assembly 16, ensuring the integrity of the flexible protective sleeve 28.

[0044] One end of the flexible protective sleeve 28 is an open ring structure, allowing it to be lifted and opened. Specifically, the flexible protective sleeve 28 has a notch 30 that extends along the axial direction of the lens barrel assembly 10 and from one end of the flexible protective sleeve 28 toward the other end, with a certain distance between them. Along the axial direction of the lens barrel assembly 10, the length of the notch 30 is greater than the length of the outer end of the first battery assembly 16, so that the entire outer end of the first battery assembly 16 can be exposed after the flexible protective sleeve 28 is lifted, so that the battery can be replaced.

[0045] The first battery 24 is a rechargeable battery, and the lens barrel assembly 10 is provided with a charging port 32, which is electrically connected to the first battery 24. Optionally, the charging port 32 is exposed outside the flexible protective sleeve 28. Since the first battery 24 is a built-in battery, its replacement frequency is low and the replacement operation is relatively cumbersome. Therefore, the first battery 24 is designed as a rechargeable battery, and a charging port 32 is provided on the lens barrel assembly 10. When the first battery 24 is low on power, it can be charged using a charger without having to remove it due to low power.

[0046] Please see Figure 5 and Figure 6 In one embodiment, the first battery assembly 16 further includes a first battery cover 34, which is detachably mounted to the opening of the first mounting groove 20 via a fastener 36 to prevent the first battery 24 from falling out of the first mounting groove 20. This opening is the opening connecting the first mounting groove 20 to the outside, and the outer end of the first battery assembly 16 is the first battery cover 34. At least a portion of the flexible protective sleeve 28 is movable relative to the lens barrel assembly 10 to expose the fastener 36 and the first battery cover 34. At this point, the fastener 36 can be separated from the lens barrel assembly 10 using a tool, allowing the first battery cover 34 to be removed from the lens barrel assembly 10, thereby exposing the first battery 24. Since the first battery 24 is replaced infrequently, a relatively cumbersome but structurally simple method can be chosen: using the fastener 36 to detachably mount the first battery cover 34 onto the lens barrel assembly 10, thus simplifying the structure of the first battery assembly 16.

[0047] Optionally, the fastener 36 is a screw. The screw passes through the first battery cover 34 and is threadedly connected to the lens barrel assembly 10. By tightening or loosening the screw with a screwdriver, the first battery cover 34 can be disassembled or installed, thereby completing the replacement of the first battery 24. In an optional example, the two ends of the first battery cover 34 in the axial direction of the lens barrel assembly 10 are respectively connected to the lens barrel assembly 10 by screws to enhance the connection stability between the first battery cover 34 and the lens barrel assembly 10.

[0048] Optionally, the opening of the first mounting groove 20 is stepped, which can be used to support the first battery cover 34 to reduce the assembly difficulty of the first battery cover 34.

[0049] A sealing ring 38 is provided between the first battery cover 34 and the lens barrel assembly 10. The first battery cover 34 and the lens barrel assembly 10 form a sealed fit through the sealing ring 38 to prevent external water, dust, etc. from entering the lens barrel assembly 10 through the gap between the first battery cover 34 and the lens barrel assembly 10, thereby achieving a waterproof and dustproof effect. Optionally, the outer periphery of the first battery cover 34 is provided with an annular groove, and the sealing ring 38 is installed in the annular groove to provide a certain limiting effect on the sealing ring 38 and reduce the assembly difficulty.

[0050] The lens barrel assembly 10 has a groove 40 at the opening of the first mounting groove 20, and the groove 40 surrounds the outer periphery of the first battery cover 34. The flexible protective sleeve 28 has a protrusion 42 corresponding to the groove 40. When the flexible protective sleeve 28 covers the first battery cover 34, the protrusion 42 is inserted into the groove 40, thereby forming a concave-convex fit on the outer periphery of the first battery cover 34, further improving the waterproof and dustproof effect.

[0051] Optionally, the number of grooves 40 can be one, which is an annular groove 40 surrounding the outer periphery of the first battery cover 34; or the number of grooves 40 can be multiple, with multiple grooves 40 arranged at intervals along the circumference of the first battery cover 34. The number of protrusions 42 is the same as the number of grooves 40, and they correspond one-to-one.

[0052] The first mounting slot 20 has a battery compartment, defined as the first battery compartment 44. The first battery 24 is housed in the first battery compartment 44. The first battery cover 34 can be detachably connected to the first battery compartment 44 via fastener 36, or it can be detachably connected to the lens barrel assembly 10 via fastener 36. Optionally, the first battery compartment 44 can be fixedly connected to the lens barrel assembly 10, for example, integrally formed; or the first battery compartment 44 can be separately set from the lens barrel assembly 10 and detachably connected.

[0053] Please see Figure 5 and Figure 7 In one embodiment, the lens barrel assembly 10 has a control circuit board 46 inside, and the first battery assembly 16 and the second battery assembly 18 are electrically connected to the optical system 12 through the control circuit board 46. The control circuit board 46 integrates a power supply circuit and adopts a parallel power supply method, so that the first battery 24 and the second battery 26 are connected in parallel to achieve complementary power. The power supply circuit is equipped with a power management module, which can detect the power of the first battery 24 and the second battery 26 in real time, and achieve the effects of charge and discharge protection, overcurrent protection and overvoltage protection, thereby extending the service life of the first battery 24 and the second battery 26.

[0054] The control circuit board 46 has a first connecting portion 48 located near the first battery 24, and the first battery assembly 16 has a corresponding second connecting portion 50. The first connecting portion 48 and the second connecting portion 50 are plugged into each other to achieve electrical connection between the first battery assembly 16 and the control circuit board 46. Optionally, one of the first connecting portion 48 and the second connecting portion 50 is a male connector terminal and the other is a female connector terminal. The first battery assembly 16 and the control circuit board 46 are electrically connected by plugging in, and they can be separated, so it will not affect the replacement of the first battery 24.

[0055] The first battery compartment 44 has a clearance opening 52, through which the second connecting portion 50 passes and engages with the first connecting portion 48. Optionally, the first battery 24 is electrically connected to the second connecting portion 50 via a wire 54, which is bendable and deformable. The second connecting portion 50 and at least a portion of the wire 54 are located radially outside the first battery 24. In an optional example, the wire 54 is bent, with one end fixed to one axial end of the first battery 24 for connection to the positive or negative terminal of the first battery 24, and the other end located radially outside the first battery 24 for electrical connection to the second connecting portion 50.

[0056] When installing the first battery 24, the second connecting part 50 can be connected to the first connecting part 48 by first bending the wire 54, then the first battery 24 can be inserted into the first mounting slot 20, and finally the first battery cover 34 can be installed. When removing the first battery 24, the first battery cover 34 can be removed first, then the first battery 24 can be taken out of the first mounting slot 20 and pulled outwards, thus separating the first connecting part 48 and the second connecting part 50. The insertion or separation of the first connecting part 48 and the second connecting part 50 does not require the use of other tools, nor does it require removing the control circuit board 46 from the lens barrel assembly 10, reducing the difficulty of replacement operations.

[0057] Please see Figure 2 , Figure 3 as well as Figure 8 In one embodiment, the flexible protective sleeve 28 has an opening 56 at the position corresponding to the second battery assembly 18. The outer end of the second battery assembly 18 is exposed through the opening 56 in the flexible protective sleeve 28, thus forming an external battery assembly. The second battery 26 acts as an external battery, and the first battery 24 acts as an internal battery. The external battery is easier to install and remove than the internal battery. When the overall power of the device is insufficient, the external battery can be replaced first. The replacement frequency of the external battery is relatively high, so the convenience of replacement needs to be considered. By providing an opening 56 on the flexible protective sleeve 28 to expose the outer end of the second battery assembly 18, the replacement of the second battery 26 is not affected by the flexible protective sleeve 28, which reduces the difficulty of replacing the second battery 26.

[0058] The second battery assembly 18 also includes a second battery cover 58, which is disposed opposite to the opening 56 so that the second battery cover 58 is exposed outside the flexible protective sleeve 28. The second battery cover 58 is detachably installed into the slot of the second mounting groove 22 via a quick-release structure, which is exposed outside the flexible protective sleeve 28. Users can quickly install and remove the second battery cover 58 via the quick-release structure, facilitating the replacement of the second battery 26. The slot of the second mounting groove 22 is the opening that connects the second mounting groove 22 to the outside, and the outer end of the second battery assembly 18 is the second battery cover 58.

[0059] A quick-release structure refers to a structure that can be disassembled and assembled without the aid of external tools. For example, the second battery cover 58 is engaged with the lens barrel assembly 10 through a quick-release structure. The user can use the quick-release structure to engage or disengage the second battery cover 58 with the lens barrel assembly 10 to fix the second battery cover 58 on the lens barrel assembly 10 or remove the second battery cover 58 from the lens barrel assembly 10. Alternatively, the second battery cover 58 can be engaged with the lens barrel assembly 10 through a quick-release structure. The user can use the quick-release structure to engage or disengage the second battery cover 58 with the lens barrel assembly 10 to fix the second battery cover 58 on the lens barrel assembly 10 or remove the second battery cover 58 from the lens barrel assembly 10.

[0060] In an optional embodiment, the quick-release structure includes an operating member 60 and a locking member 62. The operating member 60 is rotatably mounted on the second battery cover 58 and is at least partially exposed outside the second battery cover 58 for user operation. The locking member 62 is slidably mounted on the second battery cover 58 and engages with the operating member 60. When the operating member 60 rotates relative to the second battery cover 58, it drives the locking member 62 to slide relative to the second battery cover 58, allowing the locking member 62 to extend outside or retract inside the second battery cover 58, thereby locking or unlocking the second battery cover 58. In the locked state, the second battery cover 58 is fixed relative to the lens barrel assembly 10 by the locking member 62. In the unlocked state, the locking member 62 separates from the lens barrel assembly 10, and the second battery cover 58 can be removed from the lens barrel assembly 10. The user can complete the installation and removal of the second battery cover 58 by rotating the operating member 60, achieving a quick-release effect, improving the replacement efficiency of the second battery 26, and adapting to scenarios where external batteries are replaced frequently.

[0061] The second battery cover 58 is located at the opening of the second mounting groove 22. A locking hole 64 is provided within the second mounting groove 22 corresponding to the locking member 62. That is, a locking hole 64 is provided within the lens barrel assembly 10 corresponding to the locking member 62. The operating member 60 can drive the locking member 62 to slide relative to the second battery cover 58, causing the locking member 62 to insert into or retract from the locking hole 64. When the locking member 62 is inserted into the locking hole 64, it can lock the second battery cover 58, keeping the second battery cover 58 relatively fixed to the lens barrel assembly 10. When the locking member 62 is removed from the lock hole 64, the locking of the second battery cover 58 can be released, and the second battery cover 58 can be separated from the lens barrel assembly 10. Moreover, since the locking member 62 has been removed from the lock hole 64, the locking member 62 will not interfere with the lens barrel assembly 10 during the process of separating the second battery cover 58 from the lens barrel assembly 10. The locking member 62 will not affect the disassembly of the second battery cover 58, and can avoid damage to the locking member 62 due to frequent disassembly and reassembly of the second battery cover 58.

[0062] A transmission structure is provided between the operating element 60 and the locking element 62. The two are connected by the transmission structure to convert the rotational output of the operating element 60 into a linear output. The transmission structure can be a cam structure, a lead screw transmission pair structure, or a gear and rack structure, etc.

[0063] Please see Figures 8 to 10 The transmission structure includes a transmission groove 66 and a transmission protrusion 68. The transmission groove 66 is located on the side of the operating member 60 facing the locking member 62 and is elliptical in shape. The transmission protrusion 68 is correspondingly located on the locking member 62 and can be movably inserted into the transmission groove 66. The operating member 60 and the locking member 62 form a transmission engagement with the transmission groove 66 through the transmission protrusion 68. When the operating member 60 rotates relative to the second battery cover 58, the groove wall of the transmission groove 66 will press against the transmission protrusion 68, thereby pushing the locking member 62 to slide, thus locking or unlocking. Of course, in other embodiments, the positions of the transmission groove 66 and the transmission protrusion 68 can also be interchanged, that is, the transmission protrusion 68 is located on the operating member 60 and the transmission groove 66 is located on the locking member 62, and the transmission groove 66 can also be an eccentric groove that is eccentrically arranged relative to the rotation axis of the operating member 60.

[0064] Optionally, there are two locking elements 62 and two lock holes 64, with each locking element 62 corresponding to one lock hole 64. The operating element 60 is in a transmission engagement with the two locking elements 62. When the operating element 60 rotates relative to the second battery cover 58, it can drive the two locking elements 62 to move in opposite directions or towards each other, so that the two locking elements 62 are simultaneously inserted into or simultaneously withdrawn from the corresponding lock holes 64. Using one operating element 60 to drive two locking elements 62 can enhance the strength in the locked state without adding extra difficulty to the disassembly and assembly operations.

[0065] A sealing element 70 is provided between the second battery cover 58 and the lens barrel assembly 10. The sealing element 70 is located at the opening of the second mounting groove 22 and surrounds the outer periphery of the second battery cover 58. The second battery cover 58 and the lens barrel assembly 10 form a sealed fit through the sealing element 70, preventing external water, dust, etc. from flowing into the lens barrel assembly 10 through the gap between the second battery cover 58 and the lens barrel assembly 10, thus achieving a waterproof and dustproof effect.

[0066] The second mounting slot 22 is provided with a battery compartment. To distinguish it from the first battery compartment 44 in the first mounting slot 20, the battery compartment in the second mounting slot 22 is defined as the second battery compartment 72, and the second battery 26 is housed in the second battery compartment 72. Optionally, the second battery compartment 72 and the lens barrel assembly 10 can be fixedly connected, for example, integrally formed, or the second battery compartment 72 can be separately provided from the lens barrel assembly 10 and detachably connected.

[0067] A non-polarized circuit board 74 is provided on the outer side of the second battery compartment 72. Optionally, the non-polarized circuit board 74 is located at the end of the second battery compartment 72 away from the opening of the second mounting slot 22. Both ends of the second battery 26 are electrically connected to the non-polarized circuit board 74, that is, both the positive and negative terminals of the second battery 26 are electrically connected to the non-polarized circuit board 74. Optionally, the non-polarized circuit board 74 is electrically connected to the control circuit board 46, thereby realizing the electrical connection between the second battery 26 and the optical system 12. The non-polarized circuit board 74 refers to a circuit board with a non-polarized circuit. The non-polarized circuit does not distinguish between positive and negative terminals and can be connected arbitrarily without damaging the equipment or causing functional failure. Therefore, when replacing the second battery 26, the user does not need to deliberately distinguish between the positive and negative terminals of the second battery 26, completely eliminating problems such as battery damage and malfunction caused by reversed polarity of the second battery 26, improving the convenience and fault tolerance of the second battery 26 installation operation, and adapting to the operation of non-professional operators and the usage scenarios of the load.

[0068] Optionally, a connecting circuit board 76 is provided inside the second battery cover 58. The connecting circuit board 76 is electrically connected to the non-polarized circuit board 74, and the connecting circuit board 76 and the non-polarized circuit board 74 are located at opposite ends of the second battery compartment 72. One end of the second battery 26 is electrically connected to the non-polarized circuit board 74 through the connecting circuit board 76.

[0069] A first conductive element 78 is provided on the non-polarized circuit board 74, and a second conductive element 80 is provided on the connecting circuit board 76. The first conductive element 78 and the second conductive element 80 respectively abut against both ends of the second battery 26, so that one end of the second battery 26 is electrically connected to the non-polarized circuit board 74 through the first conductive element 78, and the other end is electrically connected to the connecting circuit board 76 through the second conductive element 80. Both the first conductive element 78 and the second conductive element 80 are elastic elements, such as spring pins and spring sheets. In the assembled state, the second battery 26 will squeeze the first conductive element 78 and the second conductive element 80, causing them to be in a deformed state. Under the action of their own elastic force, the first conductive element 78 and the second conductive element 80 are pressed tightly against the second battery 26. When the observation device 1 is impacted, causing the second battery 26 to move within the second battery compartment 72, the first conductive element 78 and the second conductive element 80 can be compressed or extended to always maintain contact with the second battery 26, so as to maintain the conductivity effect and avoid power failure due to impact, thereby improving the conductivity stability and impact resistance of the second battery assembly 18.

[0070] The observation device 1 can be a monocular or binocular observation device. That is, the lens assembly 10 can contain one or two lens tubes. In an optional example, the lens assembly 10 includes a first lens tube 82 and a second lens tube 84. The second lens tube 84 is connected to the radial side of the first lens tube 82, and the two are arranged side-by-side. Optical systems 12 are respectively mounted on the first lens tube 82 and the second lens tube 84, and each optical system 12 is electrically connected to the first battery 24 and the second battery 26. Optionally, the arrangement direction of the first lens tube 82 and the second lens tube 84 is the width direction of the lens assembly 10, the axis of the first lens tube 82 and the second lens tube 84 is the axis of the lens assembly 10, and the direction perpendicular to both the width direction and the axis is the height direction of the lens assembly 10.

[0071] The optical system 12 in the first telescope tube 82 and the optical system 12 in the second telescope tube 84 can be the same type of optical system or different types of optical systems. In an optional example, the two optical systems 12 are different types of optical systems, one being an infrared optical system and the other a visible light optical system, forming a dual-light path design for infrared and visible light, which can meet the observation needs under different lighting conditions. Specifically, the optical system 12 in the first telescope tube 82 includes an infrared detector, and the optical system 12 in the second telescope tube 84 includes a white light detector.

[0072] Please see Figure 4The first mounting slot 20 is located inside the first lens barrel 82, and the second mounting slot 22 is at least partially located inside the second lens barrel 84. The first battery assembly 16 and the second battery assembly 18 are respectively installed in the first mounting slot 20 and the second mounting slot 22, so that the first battery assembly 16 is located inside the first lens barrel 82, and the second battery assembly 18 is at least partially located inside the second lens barrel 84. Installing the two battery assemblies on the two lens barrels respectively allows the center of gravity of the binocular observation device 1 to be relatively centered, avoiding the instability of handheld operation due to a severe imbalance of the center of gravity to one side. Furthermore, installing the first battery assembly 16 and the second battery assembly 18 to the first lens barrel 82 and the second lens barrel 84 respectively, with a certain distance between them, facilitates heat dissipation for both battery assemblies.

[0073] Optionally, the outer ends of the first battery assembly 16 and the second battery assembly 18 are located on opposite sides of the first telescope tube 82 and the second telescope tube 84, respectively. That is, the first battery cover 34 is located on the side of the first telescope tube 82 away from the second telescope tube 84, and the second battery cover 58 is located on the side of the second telescope tube 84 away from the first telescope tube 82. When using the observation device 1, the user usually holds the first telescope tube 82 and the second telescope tube 84 vertically with both hands. At this time, the first battery cover 34 and the second battery cover 58 are on the left and right sides of the telescope tube assembly 10, respectively, so they do not affect the user's handheld use.

[0074] A flexible protective sleeve 28 covers the first lens barrel 82 and the second lens barrel 84. A notch 30 is provided on the portion of the flexible protective sleeve 28 covering the first lens barrel 82, and an opening 56 is provided on the portion of the flexible protective sleeve 28 covering the second lens barrel 84, thereby covering the first battery cover 34 on the first lens barrel 82 and exposing the second battery cover 58 on the second lens barrel 84. Optionally, the portions of the flexible protective sleeve 28 covering the first lens barrel 82 and the portions covering the second lens barrel 84 can be a single unit, i.e., the two parts are integrally formed, or they can be two separate parts.

[0075] The first lens barrel 82 and the second lens barrel 84 are aligned axially. The first mounting groove 20 extends axially along the first lens barrel 82, and the second mounting groove 22 extends axially along the arrangement direction of the second lens barrel 84 and the first lens barrel 82. That is, the first battery compartment 44 extends axially along the lens barrel assembly 10, and the second battery compartment 72 extends axially along the width direction of the lens barrel assembly 10. When the first battery assembly 16 and the second battery assembly 18 are respectively installed into the first mounting groove 20 and the second mounting groove 22, the first battery 24 is arranged axially and the second battery 26 is arranged axially. The two battery assemblies form an orthogonal layout, resulting in high internal space utilization of the lens barrel assembly 10, a more compact layout, and reduced impact of the dual battery assembly design on the overall size of the device. Of course, in other embodiments, the second mounting groove 22 may also be arranged axially along the second lens barrel 84.

[0076] In an alternative example, the length direction of the first battery 24 is aligned with the axial direction of the first lens barrel 82, the length direction of the second battery 26 is aligned with the width direction of the lens barrel assembly 10, and the length directions of the first battery 24 and the second battery 26 are perpendicular to each other.

[0077] The second mounting slot 22 extends from the second mirror tube 84 into the first mirror tube 82 along its width. That is, part of the second mounting slot 22 is inside the second mirror tube 84, and part is inside the first mirror tube 82. When the second battery assembly 18 is installed in the second mounting slot 22, one end of the second battery 26 is located inside the second mirror tube 84, and the other end is located inside the first mirror tube 82. Since there are two second batteries 26 and one first battery 24, the weight of the second battery assembly 18 will be greater than that of the first battery assembly 16. Extending one end of the second battery 26 into the first mirror tube 82 makes the center of gravity of the observation device 1 more stable, preventing instability from affecting handheld stability.

[0078] The observation device 1 of the present invention has at least the following beneficial effects: 1. A combination of a rigid lens barrel and a flexible protective sleeve 28 is adopted. For example, a combination design using a magnesium alloy lens barrel assembly 10 and a soft rubber modified PVC flexible protective sleeve 28 solves the contradiction between the consistency of multiple optical axes and the grip feel, while avoiding the process defects of traditional soft rubber materials. The lens barrel assembly 10 is made of magnesium alloy, which has low density and high rigidity, ensuring the assembly accuracy of the optical system 12 and keeping the optical axes of different optical systems 12 consistent. The flexible protective sleeve 28, made of soft rubber modified PVC material, can adapt to complex inverted shapes, reducing molding difficulty, and taking into account weather resistance and feel. At the same time, the flexible protective sleeve 28 can cover the first battery assembly 16, taking into account both appearance and practicality.

[0079] 2. The use of a dual-battery system, with both an internal and external battery, increases the overall power capacity and improves the battery life of the observation device 1. Both the internal and external batteries are removable, allowing users to replace them themselves. Furthermore, when replacing one battery, the other continues to power the optical system 12, enabling battery replacement without power interruption and preventing downtime. Additionally, the first battery assembly 16 and the second battery assembly 18 employ a dual-battery orthogonal layout, significantly improving battery life without increasing overall size or compromising handheld stability. The complementary power supply of the first and second battery assemblies enhances the reliability of the observation device 1, making it suitable for extended outdoor use.

[0080] 3. The concealed, removable built-in battery structure (i.e., the first battery assembly 16) achieves a balance between regulatory compliance and aesthetic appeal. By covering the concealed fasteners 36 and the first battery cover 34 with a flexible protective sleeve 28, disassembly can be performed simply by lifting the flexible protective sleeve 28. This satisfies the regulatory requirement of easy disassembly with simple tools while ensuring the overall appearance of the machine is integrated, thus resolving the dilemma of not being able to achieve both compliance and aesthetics.

[0081] 4. The external battery assembly achieves non-polar power supply through the non-polar circuit board 74, and forms an elastic connection with the second battery 26 by setting the first conductive element 78 and the second conductive element 80, which achieves the functions of impact resistance and stable conduction. The operating element 60 and the locking element 62 on the second battery cover 58 can realize the function of quick disassembly and assembly, and the sealing element 70 between the second battery cover 58 and the lens tube assembly 10 can form a waterproof and dustproof function, which improves the outdoor adaptability and operation convenience of the observation equipment 1.

[0082] Example b Please see Figures 11 to 13 An observation device 1 provided in this embodiment of the invention includes a telescope assembly 10, a battery module 14, and a control circuit board 46. The battery module 14 and the control circuit board 46 are electrically connected to each other and are both housed within the telescope assembly 10. The telescope assembly 10 has two mutually perpendicular axes X, Y, and Z. That is, any two of the axes X, Y, and Z are perpendicular, and the axes X, Y, and Z form a three-dimensional coordinate system, wherein the axis X is the optical axis direction of the telescope assembly 10.

[0083] The lens barrel assembly 10 includes a first lens barrel 82 and a second lens barrel 84. The first lens barrel 82 and the second lens barrel 84 are arranged side by side along the width direction Y, and their axial directions X are consistent or substantially consistent (slight deviation of the optical axis may occur due to errors during installation and assembly). A control circuit board 46 extends along the width direction Y, and in the width direction Y, the control circuit board 46 is partially located inside the first lens barrel 82 and partially located inside the second lens barrel 84. In the height direction Z, the control circuit board 46 divides the internal space of the lens barrel assembly 10 into a first space 86 and a second space 88, that is, the first space 86 and the second space 88 are respectively located on both sides of the control circuit board 46 in the height direction Z. The battery module 14 is at least partially located in the first space 86 and is stacked with the control circuit board 46, that is, the battery module 14 is at least partially located on one side of the control circuit board 46 in the height direction Z and is stacked in the height direction Z.

[0084] Optionally, both the first lens barrel 82 and the second lens barrel 84 include a first space 86 and a second space 88. The first space 86 and the second space 88 in the first lens barrel 82 are located on opposite sides of the portion of the control circuit board 46 within the first lens barrel 82, and the first space 86 and the second space 88 in the second lens barrel 84 are located on opposite sides of the portion of the control circuit board 46 within the second lens barrel 84.

[0085] In this embodiment, the observation device 1 has a control circuit board 46 located on opposite sides in the width direction Y within the second mirror tube 84 and the first mirror tube 82, respectively. It also divides the internal space of the mirror tube assembly 10 into a first space 86 and a second space 88 in the height direction Z. The battery module 14 is at least partially located within the first space 86. The control circuit board 46 is laid flat within the mirror tube assembly 10, while the battery module 14 is at least partially stacked with the control circuit board 46. This allows the control circuit board 46 and the battery module 14 to fully utilize the internal space of the mirror tube assembly 10 in both the width direction Y and the height direction Z, effectively reducing the overall size of the observation device 1 and achieving product miniaturization. Furthermore, since both the second mirror tube 84 and the first mirror tube 82 contain portions of the control circuit board 46, the components within these tubes can be connected to the control circuit board 46 using a proximity-based electrical connection method, shortening the wiring distance and facilitating connection between the control circuit board 46 and the components within the second and first mirror tubes 84 and 82, thereby reducing assembly difficulty.

[0086] It should be noted that the control circuit board 46 is laid flat within the lens barrel assembly 10. This can be because the thickness direction of the control circuit board 46 is aligned with the height direction Z of the lens barrel assembly 10, or the thickness direction of the control circuit board 46 is tilted at a small angle relative to the height direction Z of the lens barrel assembly 10, such as 0° to 10°. In an optional example, the thickness direction of the control circuit board 46 is aligned with the height direction Z of the lens barrel assembly 10 to avoid the first space 86 and the second space 88 becoming wider at one end and narrower at the other due to the tilt of the control circuit board 46, which would affect the installation of other components within the lens barrel assembly 10.

[0087] Please see Figures 13 to 15 In one embodiment, the battery module 14 includes a first battery assembly 16 and a second battery assembly 18. Both the first battery assembly 16 and the second battery assembly 18 are electrically connected to the control circuit board 46 to form a dual-battery power supply design, thereby increasing the total capacity of the battery module 14 and extending the battery life of the observation device 1.

[0088] The first battery assembly 16 is located on the control circuit board 46 on the Y-side of the width direction, and the second battery assembly 18 is located on the Z-side of the control circuit board 46, and they are stacked together. The control circuit board 46, the second battery assembly 18, and the first battery assembly 16 are arranged in different directions to make full use of the internal space of the telescope assembly 10 in two different directions (i.e., the Z-side of height and the Y-side of width), thereby improving space utilization and reducing the overall volume of the observation device 1.

[0089] The first battery assembly 16 and the second battery assembly 18 can be mounted on the same telescope tube or on two separate telescope tubes. In an optional example, the first battery assembly 16 is mounted on the first telescope tube 82, and the second battery assembly 18 is mounted on the second telescope tube 84. By mounting the two battery assemblies on two separate telescope tubes, the center of gravity of the observation device 1 is prevented from being severely biased to one side due to the installation of two battery assemblies.

[0090] The first lens barrel 82 has a first battery compartment 44 located on one side of the control circuit board 46 in the width direction Y. The first battery compartment 44 is located within the first space 86 and / or the second space 88. The first battery compartment 44 has a first storage cavity 90, and the first battery assembly 16 includes a first battery 24 located within the first storage cavity 90.

[0091] Optionally, the first battery compartment 44 may be entirely located within the first space 86 or the second space 88, or it may be partially located within the first space 86 and partially located within the second space 88. In an optional example, the end of the control circuit board 46 away from the second lens barrel 84 is spaced apart from the first lens barrel 82, the first battery compartment 44 is located between the control circuit board 46 and the first lens barrel 82, and part of the first battery compartment 44 is located within the first space 86 and the other part is located within the second space 88.

[0092] The second lens barrel 84 contains a second battery compartment 72, which is located on the Z-side of the control circuit board 46 in the height direction and housed within the first space 86. The second battery compartment 72 has a second receiving cavity 92, and the second battery assembly 18 includes a second battery 26 located within the second receiving cavity 92. Both the first battery compartment 44 and the second battery compartment 72 are located between the control circuit board 46 and the lens barrel assembly 10. The first battery compartment 44 is located on the Y-side of the control circuit board 46 in the width direction, and the second battery compartment 72 is located on the Z-side of the control circuit board 46 in the height direction. This arrangement ensures that the first battery 24 and the second battery 26 are located on different sides of the control circuit board 46, maximizing the space between the control circuit board 46 and the lens barrel assembly 10.

[0093] Understandably, the first battery compartment 44 can be part of the first battery assembly 16 or part of the first lens barrel 82. For example, when the first battery compartment 44 is detachably connected to the first lens barrel 82, the first battery compartment 44 can be part of the first battery assembly 16; when the first battery compartment 44 is integrally formed with the first lens barrel 82, the first battery compartment 44 can be part of the first lens barrel 82. Similarly, the second battery compartment 72 can be part of the second battery assembly 18 or part of the second lens barrel 84. For example, when the second battery compartment 72 is detachably connected to the second lens barrel 84, the second battery compartment 72 can be part of the second battery assembly 18; when the second battery compartment 72 is integrally formed with the second lens barrel 84, the second battery compartment 72 can be part of the second lens barrel 84. In an optional example, the first battery compartment 44 is integrally formed with the first lens barrel 82, and the first battery compartment 44 is part of the first lens barrel 82; the second battery compartment 72 is detachably connected to the second lens barrel 84, and the second battery compartment 72 is part of the second battery assembly 18.

[0094] Optionally, the first battery 24 and the second battery 26 are connected in parallel, so that the first battery 24 and the second battery 26 can power the device together or power the device individually. Both the first battery 24 and the second battery 26 are removable relative to the lens barrel assembly 10. In case of insufficient power or battery damage, the user can replace the corresponding battery himself. When one battery is replaced, the other battery can still power the device, achieving the effect of replacing batteries without interrupting power.

[0095] The second storage cavity 92 extends along the width direction Y, and one end of the second storage cavity 92 extends into the first mirror tube 82. That is, one end of the second battery compartment 72 is connected to the second mirror tube 84, and the other end extends into the first mirror tube 82 along the width direction. The second storage cavity 92 forms an opening on one side of the second mirror tube 84 in the width direction Y. The second battery 26 is inserted into the second storage cavity 92 through the opening along the width direction Y, so that one end of the first battery 24 is located in the second mirror tube 84 and the other end is located in the first mirror tube 82. The first storage cavity 90 extends along the axial direction X, and the first battery 24 is entirely located in the first mirror tube 82. The second battery assembly 18 extends along the width direction Y of the mirror tube assembly 10, and the first battery assembly 16 extends along the axial direction X of the mirror tube assembly 10, so that the second battery assembly 18 and the first battery assembly 16 form an orthogonal or near-orthogonal layout to improve space utilization and reduce the overall volume of the observation device 1. In an alternative example, the second battery assembly 18 and the first battery assembly 16 are perpendicular to each other, forming an orthogonal layout.

[0096] Optionally, the second battery assembly 18 has a higher charge and weight than the first battery assembly 16. For example, the number of second batteries 26 is greater than the number of first batteries 24, so that the second battery assembly 18 has a higher charge and weight than the first battery assembly 16. Extending the second battery assembly 18 along the width direction Y of the telescope assembly 10 and extending from the second telescope tube 84 into the first telescope tube 82 can make the weight of the observation device 1 more balanced on both sides in the width direction, and bring the center of gravity closer to the center.

[0097] Please see Figure 16 In one embodiment, the first battery assembly 16 is disposed on the first lens barrel 82 and located on one side of the control circuit board 46 in the width direction Y. The control circuit board 46 has a first connecting part 48 on the side of the control circuit board 46 in the width direction Y that is close to the first lens barrel 82 and close to the first battery assembly 16. The first battery assembly 16 is electrically connected to the first connecting part 48, so that the first battery assembly 16 and the control circuit board 46 form a connection mode of proximity, which can shorten the cable distance and reduce signal interference.

[0098] The first battery assembly 16 further includes a second connecting portion 50. The first battery 24 is electrically connected to the second connecting portion 50 via a wire 54. The second connecting portion 50 is inserted into and electrically connected to the first connecting portion 48 to achieve electrical connection between the first battery assembly 16 and the control circuit board 46. Optionally, one of the first connecting portion 48 and the second connecting portion 50 is a male connector end and the other is a female connector end. The first connecting portion 48 and the second connecting portion 50 are inserted together or separated along the width direction.

[0099] The second battery assembly 18 is disposed on the second lens barrel 84. The control circuit board 46 has a third connection part 94 on the side of the second lens barrel 84 in the width direction Y. That is, the control circuit board 46 has a third connection part 94 on the side of the second battery assembly 18. The second battery assembly 18 is electrically connected to the third connection part 94, so that the second battery assembly 18 and the control circuit board 46 form a connection method of proximity, which can shorten the cable distance and reduce signal interference.

[0100] The second battery assembly 18 further includes a fourth connecting portion 96, to which the second battery 26 is electrically connected. The fourth connecting portion 96 is inserted into and engaged with the third connecting portion 94 to form an electrical connection, thereby realizing the electrical connection between the second battery assembly 18 and the control circuit board 46. Optionally, one of the third connecting portion 94 and the fourth connecting portion 96 is a male connector terminal and the other is a female connector terminal. The third connecting portion 94 and the fourth connecting portion 96 are inserted together or separated along the width direction.

[0101] Optionally, the third connection part 94 is located on the side of the control circuit board 46 away from the first space 86, and the second battery assembly 18 is located in the first space 86 and stacked with the control circuit board 46. By placing the third connection part 94 on the side of the control circuit board 46 away from the first space 86, the third connection part 94 can be prevented from affecting the stacking of the second battery assembly 18 and the control circuit board 46.

[0102] Please see Figure 16 and Figure 17 In one embodiment, the observation device 1 further includes an optical system 12, which includes an eyepiece module 98. The eyepiece module 98 is located at one end of the lens tube assembly 10 in the axial direction X. The control circuit board 46 extends out of the battery module 14 along the axial direction X on the side near the eyepiece module 98. An eyepiece connection part 100 is provided on the side of the control circuit board 46 extending out of the battery module 14 towards the eyepiece module 98. The eyepiece connection part 100 is not blocked by the battery module 14 and is close to the eyepiece module 98. The eyepiece module 98 is electrically connected to the eyepiece connection part 100, thereby forming a connection mode of proximity between the eyepiece module 98 and the control circuit board 46.

[0103] The specific connection method between the eyepiece module 98 and the eyepiece connector 100 is not limited, such as plugging, soldering, or bonding. In an optional example, the eyepiece module 98 is electrically connected to the eyepiece conductive sheet 102, which is bonded to the eyepiece connector 100 to achieve the effect of electrical connection. The thickness of the eyepiece conductive sheet 102 is relatively small, and its overall height after bonding with the eyepiece connector 100 is relatively small, forming a low-profile mounting method to avoid interference with other components due to excessive height.

[0104] The eyepiece module 98 includes two eyepiece assemblies 104 and two display screen assemblies 106. The two eyepiece assemblies 104 and the two display screen assemblies 106 correspond one-to-one and are arranged along the axial direction X of the lens barrel assembly 10. One eyepiece assembly 104 and the display screen assembly 106 are located in the first lens barrel 82, and the other eyepiece assembly 104 and the display screen assembly 106 are located in the second lens barrel 84.

[0105] There is one eyepiece connection part 100, located at the center of the control circuit board 46 in the width direction Y. Two display screen assemblies 106 are located on either side of the eyepiece connection part 100 in the width direction Y, and both display screen assemblies 106 are connected to the eyepiece connection part 100. Optionally, there is one eyepiece conductive sheet 102, and both display screen assemblies 106 are connected to the eyepiece conductive sheet 102. The eyepiece conductive sheet 102 is then electrically connected to the eyepiece connection part 100, which allows both display screen assemblies 106 to be electrically connected to the control circuit board 46, reducing assembly difficulty.

[0106] Optionally, the eyepiece module 98 also includes a mounting bracket, on which two eyepiece assemblies 104 are fixed respectively, and the display assembly 106 is fixed on the corresponding eyepiece assembly 104. The mounting bracket is connected to the lens barrel assembly 10, so that the eyepiece assembly 104 and the display assembly 106 can be installed as a whole onto the lens barrel assembly 10.

[0107] Please see Figure 16 and Figure 18 In one embodiment, the optical system 12 further includes an objective lens module 108, and the objective lens module 108 and the eyepiece assembly 104 are respectively disposed at both ends of the lens barrel assembly 10 along the axial direction X. The control circuit board 46 extends axially X outwards from the battery module 14 on the side near the objective lens module 108, and an objective lens connection portion 110 is provided on the side of the control circuit board 46 extending towards the objective lens module 108 and outwards from the battery module 14. That is, the control circuit board 46 extends axially X outwards from the battery module 14 on both sides, and an eyepiece connection portion 100 is provided on the side near the eyepiece module 98, and an objective lens connection portion 110 is provided on the side near the objective lens module 108. The objective lens connection portion 110 is not obstructed by the battery module 14 and is disposed close to the objective lens module 108. The objective lens module 108 is electrically connected to the objective lens connection portion 110, thereby forming a close connection between the objective lens module 108 and the control circuit board 46.

[0108] The specific connection method between the objective lens module 108 and the objective lens connector 110 is not limited, such as plugging, soldering, or bonding. In an optional example, the objective lens module 108 is electrically connected to the objective lens conductive sheet 112, which is bonded to the objective lens connector 110 to achieve the effect of electrical connection. The objective lens conductive sheet 112 has a relatively small thickness, and its overall height after bonding with the objective lens connector 110 is relatively small, forming a low-profile mounting method to avoid interference with other components due to excessive height.

[0109] There are two objective lens modules 108, each independently mounted to the lens barrel assembly 10. One objective lens module 108 is mounted in the first lens barrel 82, and the other is mounted in the second lens barrel 84. There are also two objective lens connection parts 110, located on opposite sides of the control circuit board 46 in the width direction Y. The two objective lens modules 108 are arranged along the width direction Y, with the two objective lens connection parts 110 positioned close to each of the two modules. Each objective lens module 108 is electrically connected to an objective lens conductive plate 112, and through the conductive plate 112, is electrically connected to a corresponding objective lens connection part 110, ensuring that both objective lens modules 108 are closely connected to the control circuit board 46.

[0110] In an optional example, the objective lens module 108, the control circuit board 46, and the eyepiece module 98 are arranged sequentially along the axial direction X. The control circuit board 46 is located between the objective lens module 108 and the eyepiece module 98, and its two axial ends are electrically connected to the objective lens module 108 and the eyepiece module 98, respectively. That is, the objective lens connecting part 110 and the eyepiece connecting part 100 are respectively located at the two axial ends of the control circuit board 46. The objective lens conductive sheet 112 is located on the axial side of the objective lens module 108 near the control circuit board 46, and the eyepiece conductive sheet 102 is located on the axial side of the eyepiece module 98 near the control circuit board 46. The objective lens module 108, the control circuit board 46, and the eyepiece module 98 are connected sequentially along the axial direction X. The second battery assembly 18 is located on the control circuit board 46 on the Z side in the height direction and is located between the objective lens module 108 and the eyepiece module 98 in the axial direction X, so as to make the overall layout compact.

[0111] Please see Figure 13 and Figure 19 In one embodiment, the observation device 1 further includes a heat sink 114, which is thermally connected to the control circuit board 46 and located within the second space 88. The heat generated by the control circuit board 46 during operation can be transferred to the heat sink 114, thereby aiding in heat dissipation and enhancing the heat dissipation effect of the control circuit board 46, preventing it from overheating and affecting normal operation. Optionally, the second battery assembly 18 and the heat sink 114 are located on opposite sides of the control circuit board 46 in the height direction Z, to fully utilize the internal space of the lens barrel assembly 10 and prevent the heat sink 114 and the second battery assembly 18 from interfering with each other.

[0112] Along the height direction Z, the height of the first space 86 is greater than the height of the second space 88, and the heat sink 114 is located in the second space 88.

[0113] Optionally, the heat sink 114 can be located inside the second lens barrel 84, inside the first lens barrel 82, or both the second lens barrel 84 and the first lens barrel 82 may have heat sinks 114, which can be arranged according to the actual heat dissipation requirements of the control circuit board 46. In an optional example, the heat sink 114 is located inside the second lens barrel 84.

[0114] Optionally, the lens barrel assembly 10 is a metal part, such as a magnesium alloy part. The heat sink 114 is thermally connected to the lens barrel assembly 10. The heat on the control circuit board 46 can be conducted to the heat sink 114 first, and then from the heat sink 114 to the lens barrel assembly 10, so that the heat can be dissipated to the external environment by the lens barrel assembly 10.

[0115] The control circuit board 46 has a target heat-generating area, which is the area on the control circuit board 46 that generates a high amount of heat. A heat spreader 116 is provided between the heat sink 114 and the target heat-generating area, and the heat spreader 116 is thermally connected to both the control circuit board 46 and the heat sink 114. After the target heat-generating area generates heat, the heat can first be transferred to the heat spreader 116, and then from the heat spreader 116 to the heat sink 114, using the heat spreader 116 and the heat sink 114 to dissipate heat from the control circuit board 46. After the heat is transferred to the heat spreader 116, the heat will quickly diffuse outwards on the heat spreader 116, forming a uniform heat effect. This prevents heat from concentrating in the target heat-generating area, avoiding excessively high local temperatures in the lens barrel assembly 10 corresponding to the target heat-generating area, which would affect grip and use. Furthermore, the uniform heat effect can reduce heat flux density, increase the effective heat dissipation area, and improve the heat dissipation effect.

[0116] The target heat-generating area includes the main heat-generating electronic components, which are those that generate significant heat during operation. These main heat-generating electronic components include one or more of the following: System-on-Chip (SOC), DDR memory module, and eMMC storage module. The heat spreader 116 is attached to the main heat-generating electronic components to form a heat conduction connection, shortening the heat transfer path between the heat spreader 116 and the main heat sources on the control circuit board 46. This allows the main heat on the control circuit board 46 to be quickly conducted to the heat spreader 116, thereby enhancing the heat dissipation effect of the control circuit board 46.

[0117] The second battery assembly 18 is located in the first space 86, and the main heating electronic component is located in the second space 88, so that the main heating electronic component and the second battery assembly 18 are located on both sides of the thickness of the control circuit board 46, thus avoiding the problem of mutual interference between the heat generated by the second battery assembly 18 and the main heating electronic component.

[0118] Example c Please see Figure 20 The observation device 1 provided in this embodiment of the invention is a binocular telescope, including a first telescope tube 82 and a second telescope tube 84. Different optical systems are installed inside the two telescope tubes, one containing a visible light imaging module and the other containing an infrared imaging module. A ranging module 118, a supplementary light assembly 120, and a knob assembly 122 are also provided between the first telescope tube 82 and the second telescope tube 84, wherein the knob assembly 122 is a magnification knob. The supplementary light assembly 120 and the magnification knob are preferably coaxially arranged and both located at the top of the telescope tubes. The ranging module 118 can be located below the supplementary light assembly 120. In this way, the binocular telescope can simultaneously acquire three different data sources: infrared, visible light, and laser. Furthermore, its overall layout is compact and aesthetically pleasing, which is beneficial for miniaturization. The structural design of each part of this binocular telescope is the same as in embodiments a and b, and will not be described again here.
