Technical Field

[0002] This application relates to the field of optical equipment technology, and in particular to a binoculars photoelectric telescope. Background Technology

[0003] In the fields of military reconnaissance, field search and rescue, and civilian observation, binoculars are widely used because they can provide binocular observation effects that conform to human stereoscopic vision.

[0004] In order to achieve binocular stereo imaging, existing binocular photoelectric telescopes require two independent optical path systems (binocular design) to be placed side by side, which significantly increases the size and weight of the whole device. At the same time, its functional modules (such as batteries and ranging units) need to be externally mounted, which further affects portability. However, if the functional modules are built in, it will cause the problem of the coordinated layout of functional modules and optical systems in a limited space, and it will be impossible to balance the relationship between the compact structure of the whole device and binocular vision.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Please refer to Figures 1 and 2. The binoculars in this embodiment can be either a single-objective binoculars or a dual-objective binoculars. This embodiment uses a single-objective binoculars as an example for explanation. The binoculars include a housing 1, which includes a first lens tube 11, a second lens tube 12, and a central axis housing 13 connecting the two lens tubes.

[0043] The first lens barrel 11 contains a mechanism module 6, which is used for image acquisition.

[0044] The second telescope tube 12 contains a battery compartment module 10, which is used to provide power to the binoculars.

[0045] The binocular photoelectric telescope provided in this application reconstructs the traditional symmetrical dual-optical-path system of binoculars into an asymmetrical division of labor design (the imaging module 6 is integrated into the first tube 11, and the battery compartment module 10 is arranged in the second tube 12). This improves axial space utilization while maintaining binocular observation, avoiding the volume redundancy caused by external mounting or lateral expansion of the electronic module (battery compartment module 10) in traditional solutions. Simultaneously, the first tube 11 independently accommodates the complete imaging optical path assembly (engineering module 6), completely avoiding the beam splitting energy loss of monocular binocular solutions.

[0046] Furthermore, both the first lens barrel 11 and the second lens barrel 12 have an eyepiece module 2 and a display module near the eyepiece end. Both display modules are used to display images acquired by the mechanism module 6. In addition, the first lens barrel 11 also contains an objective lens module 5 and a main control module 7. The main control module 7 is connected to the mechanism module 6 and the display module via signals. The mechanism module 6 is located in the optical path of the objective lens module 5. The mechanism module 6 acquires images through the objective lens module 5 and transmits the images to the main control module 7.

[0047] The mechanism module 6 can be, for example, at least one of an infrared mechanism module, a visible light mechanism module, and a low-light mechanism module.

[0048] The movement module 6 is located inside the first lens barrel 11 at one end away from the corresponding eyepiece module 2, and the battery compartment module 10 is located inside the second lens barrel 12 at one end away from the corresponding eyepiece module 2.

[0049] Furthermore, a range-measuring module 9 can be further installed within the second telescope tube 12. The range-measuring module 9 is used to measure the distance between the target object and the observer. The inclusion of the range-measuring module 9 increases the functionality of the telescope, broadening its application range. Moreover, through the decoupling design of the mechanism module 6 and the range-measuring module 9, the autofocus mechanism can respond independently to the range measurement data, improving focusing accuracy compared to the linked focusing system of traditional optoelectronic integrated telescope tubes.

[0050] The ranging module 9 and the battery compartment module 10 are located at the end of the second lens barrel 12 away from the corresponding eyepiece module 2. The ranging module 9 is located on the side of the battery compartment module 10 opposite to the corresponding eyepiece module 2. The battery compartment module 10 is arranged along the axial direction of the second lens barrel 12.

[0051] More specifically, inside the first lens barrel 11 at the end furthest from the eyepiece module 2, an objective lens module 5, a mechanism module 6, and a main control module 7 are arranged sequentially from the direction furthest from the eyepiece module 2 toward the direction closer to the eyepiece module 2; inside the other end, a display module and an eyepiece module 2 are arranged sequentially. In the second lens barrel 12, in addition to the eyepiece module 2 and display module also being arranged at one end, a rangefinder module 9 and a battery compartment module 10 can also be arranged. The rangefinder module 9 is located on the side of the battery compartment module 10 opposite to the corresponding eyepiece module 2, and is used to measure the distance between the target object and the observer and display it on the display module.

[0052] The ranging module 9 can specifically be a laser ranging module, including a laser emitting part and a laser receiving part. The laser ranging module can be set close to the inner front end of the second lens barrel 12 (i.e., the end away from the eyepiece module 2). The laser emitting optical axis and the laser receiving optical axis are preferably parallel to the axis of the second lens barrel 12. A laser-transmitting window should also be provided at the front end of the second lens barrel 12 to realize laser emission and reception. The battery compartment module 10 is located between the ranging module 9 and the corresponding eyepiece module 2. In a specific embodiment, the battery compartment module 10 includes a battery compartment and a removable battery located inside the second lens barrel 12. The battery compartment is used to hold the battery. To realize battery removal and replacement, a battery compartment opening can be opened in the barrel wall of the second lens barrel 12, and the battery compartment opening can be opened and closed using a battery compartment cover. When the battery compartment cover is opened, the battery can be taken out and put in from the battery compartment opening.

[0053] A magnification adjustment component 4 and a focusing structure 3 are sequentially mounted on the central axis housing 13 between the two lens barrels. The magnification adjustment component 4 is located near the eyepiece module 2 and is electrically connected to the main control module 7 and / or the display module. It is used to adjust the magnification of the image output by the display module. In other words, the magnification adjustment component 4 can be directly electrically connected to the main control module 7, and the main control module 7 can adjust the magnification according to the angle change signal received from the magnification adjustment component 4. Of course, the magnification adjustment component 4 can also be directly electrically connected to the display module, and the display module can also directly adjust its own magnification according to the angle change signal. The focusing structure 3 is connected to the objective lens module 5 or the mechanism module 6 and is used to adjust the distance between the objective lens module 5 and the mechanism module 6. The distance between the side of the first lens barrel 11 and the second lens barrel 12 away from the central axis housing 13 and the magnification adjustment component 4 and the focusing structure 3 is designed to allow the user to operate the magnification adjustment component 4 and the focusing structure 3 with one hand. Both the focusing structure 3 and the magnification adjustment component 4 are located on the central axis housing 13 of the telescope. By compactly and rationally arranging the component structure inside the telescope tube, the overall size of the tube is reduced, allowing users to easily operate the focusing and magnification adjustment with one hand. At the same time, the overall layout of the telescope is more compact and rational. Regardless of whether the user is left- or right-handed, they can focus and adjust the magnification with one hand, making it very convenient to use.

[0054] In some embodiments, the centerline at the maximum distance between the upper and lower surfaces of the central housing 13 is located on one side of the plane containing the centerline of the first lens tube 11 and the centerline of the second lens tube 12. That is, one side of the surface of the central housing 13 bulges outward relative to the outer surface of that side of the two lens tubes, while the other side of the central housing 13 is concave inward relative to that side of the two lens tubes. This concave side facilitates the user's grip on the telescope. The central housing 13 is not collinear with the two lens tubes, shortening the total length of the first lens tube 11, the central housing 13, and the second lens tube 12, i.e., the width of the telescope, further reducing the overall size of the binoculars and facilitating one-handed operation. The binoculars in this embodiment are single-light, single-objective telescopes, but in other embodiments, other types of telescopes, such as dual-objective telescopes, may also be used.

[0055] As shown in Figures 3 and 4, the focusing structure 3 of this embodiment includes a first guide rod 37, a connecting assembly 36, a connecting rod 34, and a focusing knob assembly 31. The focusing knob assembly 31 is located between the two lens barrels of the telescope. When the focusing knob assembly 31 rotates, it drives the connecting rod 34 to reciprocate in a direction closer to or further away from the eyepiece module 2. The end of the first guide rod 37 away from the eyepiece module 2 is connected to the lens of the telescope's movement module 6 or objective lens module 5. The end of the first guide rod 37 near the eyepiece module 2 is movably connected to the connecting assembly 36, and the other end of the first guide rod 37 is movably connected to the objective lens module 5 or movement module 6. The end of the connecting rod 34 away from the focusing knob assembly 31 is fixedly connected to the connecting assembly 36. The first guide rod 37 achieves a movable connection with the connecting rod 34 through the connecting assembly 36, effectively preventing jamming during focusing.

[0056] Specifically, in this embodiment, the connecting assembly 36 includes a pressure block 361 and a pressure plate 362. The pressure block 361 has a receiving cavity, and the pressure plate 362 has a through hole. The first guide rod 37 has a first protrusion 371 at one end near the eyepiece module 2. The first protrusion 371 is inserted into the receiving cavity, and the rod of the first guide rod 37 is inserted into the through hole of the pressure plate 362. The pressure block 361 and the pressure plate 362 are fixedly connected, sealing the first protrusion 371 in the receiving cavity of the pressure block 361, thereby movably connecting the first guide rod 37 and the connecting assembly 36. The side surface of the pressure block 361 near the eyepiece module 2 is fixedly connected to the connecting rod 34. To ensure a more stable and smooth focusing structure 3, the first protrusion 371 and the connecting component 36 can be fitted with a clearance fit, with the axial clearance between the first protrusion 371 and the connecting component 36 along the first guide rod 37 not exceeding 0.05mm. This clearance ensures stable and smooth operation of the focusing structure while reducing backlash and making the focusing transmission more precise. To further improve the smoothness of focusing, the surface of the first protrusion 371 away from the pressure plate 362 can be configured as an outwardly convex spherical surface. The end of the first guide rod 37 away from the eyepiece module 2 is movably connected to the lens of the movement module 6 or the objective lens module 5 via the second protrusion 372. This lens could be, for example, the lens in the objective lens module 5 closest to the eyepiece module 2.

[0057] As shown in Figures 2 and 5, to facilitate the installation of the focusing structure 3 and the magnification adjustment component 4, a middle shell 8 can be provided inside the central axis housing 13. This middle shell 8 is fixedly connected to the central axis housing 13 and includes a first receiving cavity 81, a connecting cavity 82, and a second receiving cavity 83 arranged sequentially along the optical axis. The first receiving cavity 81 is located on the side away from the eyepiece module 2, with the focusing structure 3 at least partially located within the first receiving cavity 81, and the magnification adjustment component 4 at least partially located within the second receiving cavity 83. The middle shell 8 facilitates the installation of the focusing structure 3 and the magnification adjustment component 4 and also provides some protection for them. During telescope assembly, the focusing structure 3 and the magnification adjustment component 4 can be installed inside the middle shell 8 first, and then the middle shell 8 can be fixedly connected to the central axis housing.

[0058] As shown in Figures 5 and 6, the focusing knob assembly 31 includes a focusing handwheel 311, a support 312, and a second guide rod 313. The focusing handwheel 311 is located within the first receiving cavity 81. The second guide rod 313 passes through the focusing handwheel 311 and is fixedly connected to it. The support 312 is located on the side of the focusing handwheel 311 near the eyepiece module 2, within the connecting cavity 82, and is fixedly connected to the middle shell 8 via a retaining ring 32. The retaining ring 32 is located within the connecting cavity 82, and the support 312 is located within the retaining ring 32. One end of the second guide rod 313 is inserted into the central hole of the support 312, and the other end is threadedly connected to the connecting rod 34. The other end of the second guide rod 313 extends out of the first receiving cavity 81. A limiting adapter block 315 is fixedly provided on the surface of the middle shell 8 away from the eyepiece module 2. A support block 314 is fixedly provided on the limiting adapter block 315. The support block 314 has a groove, and the second guide rod 313 rests in the groove. The support 312 and the support block 314 support the second guide rod 313, so that the focusing knob assembly 31 can rotate under their support. The connecting rod 34 includes a first head 341, a rod 343 and a second head 342 that are connected in sequence. The first head 341 has an internal thread, which meshes with the external thread of the second guide rod 313. The thread engagement movement is no more than 0.05mm, and the number of threads and the lead must meet the front and rear focusing margin requirements of the objective lens module 5 to make the transmission accuracy of the focusing structure better. The connecting rod 34 is located outside the middle shell 8. The surface of the middle shell 8 near the connecting rod 34 is provided with a guide groove 84. The rod part 343 is located in the guide groove 84, so that when the focusing handwheel 311 rotates, it drives the connecting rod 34 to reciprocate linearly in the direction closer to or away from the eyepiece module 2 via the second guide rod 313. When the focusing handwheel 311 is rotated, the focusing handwheel 311 drives the second guide rod 313, which is fixedly connected to it, to rotate together. When the second guide rod 313 rotates, the rotation of the connecting rod 34, which is threaded to it, is restricted by the guide groove 84. Therefore, the connecting rod 34 can only move linearly in the direction closer to or away from the eyepiece module 2, thereby driving the first guide rod 37 to move linearly accordingly, and finally realizing the focusing function.

[0059] As shown in Figures 3 and 4, to further improve the smoothness of the focusing structure 3 during adjustment, the end of the first guide rod 37 furthest from the eyepiece module 2 can be movably connected to the lens of the mechanism module 6 or the objective lens module 5. For example, a limiting block 35 can be provided, and a protruding connecting ear 331 can be provided on the lens of the mechanism module 6 or the objective lens module 5. The connecting ear 331 has an opening groove, the radial dimension of which is not less than the radial dimension of the middle rod of the first guide rod 37. The limiting block 35 has a limiting blind hole, the diameter of which is larger than the radial dimension of the second protrusion 372 of the first guide rod 37. The second protrusion 372 is located in the limiting blind hole, and the rod of the first guide rod 37 is inserted into the opening groove. The limiting block 35 is fixedly connected to the connecting ear 331, thereby forming a movable connection between the first guide rod 37 and the lens of the objective lens module 5 or the mechanism module 6.

[0060] As shown in Figures 2, 3, and 7, the objective lens module 5 of the telescope in this embodiment includes a first objective lens module 51 and a second objective lens module 52 fixedly connected. The first objective lens module 51 and the second objective lens module 52 can be fixedly connected, for example, through a threaded connection. The first objective lens module 51 is positioned close to the mechanism module 6. The binoculars also include an objective lens guide tube 33, which covers the first objective lens module 51 and is fixedly connected to the mechanism module 6. It is also connected to the drive end of the focusing structure 3 (specifically, movably connected to the first guide rod 37). At this time, a connecting lug 331 is located on the outer wall of the objective lens guide tube 33, and the first guide rod 37 is movably connected to the mechanism module 6 through the objective lens guide tube 33. The purpose of dividing the objective lens module 5 into two components (the first objective lens module 51 and the second objective lens module 52) is to facilitate the installation of the objective lens module 5. The objective lens guide tube 33 is provided to facilitate the movement of the mechanism module 6, making focusing more stable and reliable. The objective lens guide tube 33 is clearance-fitted with the first objective lens module 51. A guide limiting structure is provided between the objective lens guide tube 33 and the first objective lens module 51. For example, the guide limiting structure can be a locating pin and a sliding groove that work together. For instance, a sliding groove is provided on the first objective lens module 51, and a corresponding locating pin is provided on the objective lens guide tube 33. The height of the objective lens guide tube 33 can be appropriately adjusted, and the length of the locating pin can be adjusted accordingly, increasing the mating length between the locating pin and the sliding groove, making the guidance of the guide limiting structure more stable and reliable. The objective lens guide tube 33 is used to move in the direction defined by the guide limiting structure toward or away from the first objective lens module 51.

[0061] As shown in Figure 6, the telescope in this embodiment of the application further includes a magnification adjustment component 4, which includes a magnification adjustment handwheel 41 and an encoder 44 connected to each other. The magnification adjustment handwheel 41 is located on the side of the focusing structure 3 near the eyepiece module 2. When the magnification adjustment handwheel 41 rotates, it drives the knob of the encoder 44 to rotate. The encoder 44 is used to receive the adjustment signal from the main control module 7 or the magnification adjustment handwheel 41 and transmit the adjustment signal to the display module. The display module is used to receive the adjustment signal and adjust the magnification of the output image according to the adjustment signal.

[0062] The encoder 44 is fixed to the central housing 13, with the side of the encoder 44 having a rotating knob positioned closer to the objective lens module 5. The magnification adjustment handwheel 41 is located within the second receiving cavity 83, and its rotation drives the rotating knob to rotate as well. To facilitate and securely install the encoder 44, an encoder bracket 43 can be provided. The encoder bracket 43 is positioned between the magnification adjustment handwheel 41 and the encoder 44, and is sealed within a through hole at the end of the central housing 8 near the eyepiece module 2. The rotating knob of the encoder 44 passes through the encoder bracket 43 and connects to the magnification adjustment handwheel 41. Rotation of the magnification adjustment handwheel 41 drives both the encoder bracket 43 and the rotating knob to rotate. Manual focusing can be achieved by rotating the magnification adjustment handwheel 41; for more flexible focusing options, electronic focusing can also be used. For example, as shown in Figure 2, adjustment buttons 42 can be installed on the central shaft housing 13 on both sides of the magnification adjustment handwheel 41. The adjustment buttons 42 are electrically connected to the main control module 7. When the adjustment button 42 is pressed, it transmits the adjustment signal to the main control module 7. The main control module 7 controls the rotation knob of the encoder 44 to rotate, thereby achieving automatic focusing. The magnification adjustment component 4 and the focusing structure 3 are both located between the two lens tubes, which facilitates user operation and makes the overall structure of the telescope more compact and reasonable.

[0063] To improve the telescope's waterproof performance, sealing elements 100 can be added. For example, a first sealing ring 101 can be installed between the objective lens module 5 and the corresponding lens barrel. Specifically, the first sealing ring 101 is located on the outer wall of the objective lens module 5, and the objective lens module 5 is press-fitted with the corresponding lens barrel through the first sealing ring 101, achieving waterproofing between the objective lens module 5 and the outer shell 1. A second sealing ring 102 is provided inside the focusing knob assembly 31. For example, the second sealing ring 102 can be installed between the second guide rod 313 and the focusing handwheel 311. Specifically, the second sealing ring 102 is located on the outer wall of the second guide rod 313, and the second guide rod 313 is press-fitted with the focusing handwheel 311 through the second sealing ring 102, achieving waterproofing of the focusing knob assembly 31. A third sealing ring 103 is provided between the magnification adjustment component 4 and the focusing structure 3. Specifically, the third sealing ring 103 is located on the surface of the focusing handwheel 311 away from the eyepiece module 2. The focusing handwheel 311 is press-fitted with the fixing ring 32 through the third sealing ring 103, thereby achieving the adjustment feel of the encoder 44's rotation knob and compensating for assembly and fitting gaps. A fourth sealing ring 104 is provided between the focusing knob assembly 31 and the middle shell 8. The fourth sealing ring 104 is located on the surface of the focusing handwheel 311 away from the eyepiece module 2. The focusing knob assembly 31 is press-fitted with the middle shell 8 through the fourth sealing ring 104, thereby achieving waterproofing.

[0064] Referring further to Figures 1 and 2, in a specific embodiment, the binoculars include a first tube 11 and a second tube 12 connected to each other. The first tube 11 houses an objective lens module 5, a main control module 7, and a mechanism module 6. The mechanism module 6 is specifically an infrared mechanism module used for infrared image acquisition. The second tube 12 houses a battery compartment module 10 and a ranging module 9. The battery compartment module 10 provides power to the binoculars, and the ranging module 9 measures the distance between the target object and the observer. Both the first tube 11 and the second tube 12 have an eyepiece module 2 and a display module near the eyepiece. The infrared images acquired by the infrared mechanism module are ultimately transmitted to the two display modules in the two tubes for display, facilitating binocular observation. This binoculars not only integrate infrared and laser ranging functions but also have a reasonable overall layout, achieving a balance between compact design and binocular vision.

[0065] The binoculars provided in this application embodiment improve the layout of the mechanism module 6, the rangefinding module 9, and the battery compartment module 10. By placing the focusing structure 3 and the magnification adjustment component 4 on the central axis housing, the convenience of user adjustment is improved. At the same time, by improving the connection method, the focusing structure 3 is made more stable and smooth during focusing, thus improving the reliability of manual focusing.

[0066] Furthermore, with the development of technology, battery life has become a key factor limiting the user experience of electronic devices. To achieve long battery life, using both built-in and external batteries is a common power management strategy, especially widely used in devices such as drones and electric bicycles. Built-in and external batteries can be used in parallel to provide power simultaneously, extending the total battery life. They can also be switched between each other to meet different power needs.

[0067] However, for ease of maintenance, existing electrical equipment typically has two battery compartment structures, one for storing the internal battery and the other for storing the external battery, ensuring that the two batteries are staggered. The two battery compartment structures occupy a significant amount of space, which is detrimental to achieving lightweight design in electrical equipment.

[0068] To address the technical problem of existing battery compartment structures failing to meet lightweight design requirements due to the independent placement of external and internal batteries, this application further provides a battery compartment module structure. As shown in Figures 8 and 9, the battery compartment module 10 includes a mounting frame 01, which comprises an integrally connected outer frame 011 and an inner frame 012. The outer frame 011 is semi-cylindrical, with an outer battery compartment 0110 formed at its center, used to house an external battery 02. The inner frame 012 is cylindrical, with an inner battery compartment 0120 formed at its center, used to house an internal battery 03. The centerlines of the inner battery compartment 0120 and the outer battery compartment 0110 are parallel to each other. By optimizing the structure of the mounting frame 01, the external battery 02 and the internal battery 03 are arranged in parallel, resulting in a more compact arrangement and a smaller footprint.

[0069] The mounting bracket 01 comprises an external battery compartment 0110 and an internal battery compartment 0120, which are independent of each other. It should be noted that the mounting bracket 01 is made of insulating material, and the external battery 02 and the internal battery 03 can be two different types of batteries. The external battery 02 can be a replaceable dry cell battery, and the internal battery 03 can be a lithium battery that can be charged and discharged for a long time.

[0070] This application optimizes the battery compartment module 10, allowing the external battery 02 and the internal battery 03 to be centrally mounted on the mounting bracket 01, eliminating the need for a separate mounting bracket 01. This results in a more compact structure, occupies less space, and facilitates lightweight design. Furthermore, it reduces material consumption, contributing to lower costs.

[0071] Because the external battery 02 and the internal battery 03 are of different types, the battery fixing methods of the external battery compartment 0110 and the internal battery compartment 0120 are naturally different. As shown in Figures 8 and 9, the external battery compartment 0110 uses an elastic clamping method to fix the external battery 02. Specifically, positive electrode springs 0111 and negative electrode springs 0112 are fixed at both ends of the external battery compartment 0110, and the external battery 02 abuts between the positive electrode springs 0111 and negative electrode springs 0112. The two ends of the external battery 02 are electrically connected to the power board 05 through the positive electrode springs 0111 and negative electrode springs 0112, respectively. On the other hand, the internal battery compartment 0120 uses a direct fixing method to fix the internal battery 03. Specifically, the internal battery 03 is fixed inside the internal battery compartment 0120 by interference fit or adhesive application. Of course, the battery fixing methods of the external battery compartment 0110 and the internal battery compartment 0120 are not limited to these.

[0072] As a preferred embodiment, as shown in Figures 8 and 10, the built-in battery 03 is end-mounted. One end of the inner frame 012 has an end opening 0121, and the other end is fixed with a stop plate 0122. The end opening 0121 is used for inserting the built-in battery 03 into the inner battery compartment 0120, making it easier to install the built-in battery 03. The stop plate 0122 abuts against the end of the built-in battery 03 to limit the position of the built-in battery 03 in the inner battery compartment 0120, preventing the built-in battery 03 from becoming loose, ensuring that the built-in battery 03 is firmly fixed, reducing the risk of power failure due to improper installation, resulting in a lower failure rate and a better user experience.

[0073] As a preferred embodiment, as shown in Figures 8 and 9, the external battery 02 is side-mounted and disassembled. A side opening 0113 is formed on the side of the outer frame 011 away from the inner frame 012. The side opening 0113 allows the external battery 02 to be installed into the external battery compartment 0110, facilitating both installation and removal of the external battery 02 and ensuring that the installation paths of the external battery 02 and the internal battery 03 do not interfere with each other. The length of the side opening 0113 is greater than the length of the external battery 02, ensuring convenient installation and removal of the external battery 02.

[0074] As shown in Figures 8 and 9, a battery pull strap 04 is fixed inside the outer battery compartment 0110. The battery pull strap 04 is used to assist in removing the external battery 02. The battery pull strap 04 is a flexible strap, with one end fixedly installed. When the external battery 02 is installed, the battery pull strap 04 is pressed between the external battery 02 and the outer battery compartment 0110, ensuring that one end of the battery pull strap 04 extends outside the outer battery compartment 0110. To remove the external battery 02, simply pull the battery pull strap 04, which lifts the external battery 02, causing it to detach from the outer battery compartment 0110. This eliminates the need for forceful prying with fingers, making it easier to remove the external battery 02 and providing a better user experience. It should be noted that, considering the thickness of the battery pull strap 04, the side wall of the outer battery compartment 0110 is provided with a receiving groove to accommodate the battery pull strap 04. This prevents the outer battery 02 from not fitting snugly against the inner side wall of the outer battery compartment 0110, which would result in the outer battery 02 not being securely installed. This ensures that both ends of the outer battery 02 make good contact with the positive electrode spring 0111 and the negative electrode spring 0112, respectively, making the power supply of the outer battery 02 more stable and further improving the user experience.

[0075] As shown in Figures 8 and 10, the battery compartment module also includes a power board 05. Several support columns 013 are fixed to one end of the mounting bracket 01. The power board 05 is secured to the support columns 013 by locking screws. This ensures the power board 05 is reliably fixed and also provides sufficient space between the end of the mounting bracket 01 and the power board 05 to accommodate electronic components on the power board 05. Specifically, the power board 05 is fixed to the end of the mounting bracket 01 near the negative electrode spring 0112.

[0076] As a preferred embodiment, as shown in Figure 9, the outer battery compartment 0110 has a positive electrode slot and a negative electrode slot at both ends. The positive electrode spring 0111 is interference-fitted with the positive electrode slot, and the negative electrode spring 0112 is interference-fitted with the negative electrode slot. This ensures that the positive electrode spring 0111 and the negative electrode spring 0112 are reliably fixed, and simplifies the installation steps of the positive electrode spring 0111 and the negative electrode spring 0112, thereby reducing assembly costs.

[0077] As shown in Figures 8 and 10, the battery compartment module also includes an outer shell 06, which is fitted over the mounting bracket 01. The outer shell 06 has a disassembly hole 061, which faces the side opening 0113, facilitating the removal and installation of the external battery 02 inside the external battery compartment 0110. A protective cover 07 can be detachably installed at the disassembly hole 061 to cover the side opening 0113, preventing the external battery 02 from detaching from the external battery compartment 0110 due to impact, ensuring stable power supply from the external battery 02, and facilitating easy and flexible replacement of the external battery 02. It should be noted that the protective cover 07 may have an arc groove on the side near the external battery 02, which matches the outer surface of the external battery 02, increasing the contact area between the protective cover 07 and the external battery 02 and reducing the risk of poor contact. Both the outer shell 06 and the protective cover 07 are insulating components to prevent leakage faults.
