[0048] Reference Figures 1 to 17 A pipe endoscope probe, comprising:

[0049] The housing 10 has a receiving cavity 11 and an image acquisition window 12 communicating with the receiving cavity 11. The image acquisition window 12 can be a through hole.

[0050] Image acquisition device 30, wherein the image acquisition device 30 is disposed within the receiving cavity 11 and faces the image acquisition window 12; and

[0051] A drive / adjustment device is used to detect or adjust the image acquisition angle of the image acquisition device 30 so that the image displayed on the display 15 of the detection system 2000, which is communicatively connected to the image acquisition device 30, always remains upright.

[0052] The first control board 51 is fixedly installed inside the receiving cavity 11;

[0053] A rotary electrical connector 40 is disposed within the receiving cavity 11. The rotary electrical connector 40 includes a fixed component 401 and a rotatable component 402 electrically connected to the fixed component 401. The rotatable component 402 is rotatable relative to the fixed component 401. The image acquisition device 30 is electrically connected to the rotatable component 402 via a first electrical connection line 403. The first control board 51 is electrically connected to the first control board 51 via a second connection line 404, so that when the drive / adjustment device rotates, the rotatable component 402 can rotate with the drive / adjustment device, and the fixed component 401 can maintain its original state relative to the rotatable component 402.

[0054] In this embodiment, the drive / adjustment device is used to detect or adjust the image acquisition angle of the image acquisition device so that the image displayed by the display based on the image signal always remains upright. This prevents the image acquisition device from rotating with the endoscope probe when it is inserted into the pipe, maintaining the stability of the image acquired by the image acquisition device. This allows the user to better understand the situation inside the pipe based on the information acquired by the image acquisition device. The rotating electrical connector prevents the first electrical connection wire from getting tangled, allowing the drive / adjustment device to move better. The fixing component 401 can maintain its original state relative to the first control board 51, improving the stability of the drive / adjustment device's movement and enhancing the user experience.

[0055] In this embodiment, the driving / adjusting device includes an eccentric member 20, which is rotatably disposed in the receiving cavity 11. The image acquisition device 30 is fixedly connected to the eccentric member 20, and the image acquisition device 30 is coaxially disposed with the eccentric member 20, and rotates around the axis of the image acquisition device 30 under the action of the eccentric member 20.

[0056] With the above-described structure, when the endoscope probe is inserted into the pipe, the eccentric component 20 rotates under the influence of gravity, which in turn drives the image acquisition device 30 to rotate. This ensures that the viewing angle of the lens of the image acquisition device 30 is always forward, preventing the image acquisition device 30 from rotating with the endoscope probe when it is inserted into the pipe. This maintains the stability of the images acquired by the image acquisition device 30, allowing the user to better understand the situation inside the pipe based on the information acquired by the image acquisition device 30.

[0057] In this embodiment, the eccentric component 20 is provided with a first mounting slot 21 and a second mounting slot 201. The first mounting slot 21 is located close to the image acquisition window 12, and at least part of the image acquisition device 30 is inserted into the first mounting slot 21 so that the image acquisition device 30 is coaxially arranged with the eccentric component 20. The second mounting slot 201 is located away from the image acquisition window 12, and the rotary electrical connector 40 is installed in the second mounting slot 201. The fixing component 401 can rotate relative to the eccentric component 20. With the above structure, inserting the image acquisition device 30 into the first mounting slot 21 can, on the one hand, make the image acquisition device more stably connected to the eccentric component 20, and on the other hand, make the image acquisition device 30 and the eccentric component 20 coaxially arranged. The rotation of the image acquisition device 30 with the eccentric component 20 is smoother. Since the image acquisition device 30 and the rotary electrical connector 40 are connected by a wire, the second mounting slot is used to facilitate the simultaneous installation of the rotary electrical connector 40 and the image acquisition window 12 without the need for wire disconnection, saving installation steps. Furthermore, the eccentric component 20 is provided with a connecting block 22. The first mounting groove 21 and the second mounting groove 201 are respectively disposed on both sides of the connecting block 22. The connecting block 22 is used for connecting the connector passing through the image acquisition device 30. Using the connecting block 22, the image acquisition device 30 can be stably connected to the eccentric component 20 and the rotary electrical connector 40, preventing the image acquisition device 30 from detaching from the first mounting groove 21, thereby improving the stability of the product.

[0058] In this embodiment, the image acquisition device 30 includes a lens 31 and a second control board 32. The lens 31 is used to acquire images, and the second control board 32 receives the images acquired by the lens 31. The lens 31 can acquire images, while the imaging element on the second control board 32 converts the images into signals, which can effectively transmit the signals.

[0059] In this embodiment, an eccentric component housing 41 and a bearing 42 are also included. The eccentric component housing 41 is disposed within the receiving cavity 11, and the bearing 42 is fixedly inserted into the eccentric component housing 41. The eccentric component 20 is rotatably inserted into the bearing hole 421 of the bearing 42. Through the above structural arrangement, the bearing 42 allows the eccentric component 20 to rotate more smoothly around the rotation axis, thereby driving the image acquisition device 30 to rotate synchronously, making the product more sensitive. When the endoscope probe is flipped to the desired orientation, the image acquisition device 30 can rotate quickly and flexibly under the action of gravity, ensuring that the image acquired by the image acquisition device 30 is always facing upwards, facilitating the user's judgment of the situation inside the pipe based on the image acquired by the image acquisition device 30. The eccentric component housing 41 better protects the image acquisition device 30 and the eccentric component 20, and the eccentric component housing 41, the image acquisition device 30, and the eccentric component 20 form a whole, which also facilitates product assembly and improves production efficiency.

[0060] In this embodiment, the eccentric component 20 includes a connecting pipe 210 and a mounting base 211. The connecting pipe 210 is fixedly connected to the side of the mounting base 211 away from the image acquisition window 12. The first mounting groove 21 is disposed on the mounting base 211, and the second mounting groove 201 is the channel of the connecting pipe 210. The connecting pipe 210 is rotatably inserted into the bearing hole 421 of the bearing 42. The rotary electrical connector 40 is installed in the channel of the connecting pipe 210. This structure can support the bearing 42 and the image acquisition window 12. The acquisition device 30 and the rotary electrical connector 40, along with the eccentric component, not only ensure that the image displayed on the monitor 15, which is connected to the image acquisition device 30, is always in the correct orientation, but also allow the rotary electrical connector 40 to be installed. Furthermore, the eccentric component is rotatably fixed within the receiving cavity. The eccentric component's structure is not only simple but also facilitates the installation of other parts. The connecting pipe 210 has limiting clips 2100 at both ends to restrict the movement of the bearing 42 towards both ends of the connecting pipe 210, making the eccentric component more stable when rotating relative to the bearing 42.

[0061] In this embodiment, a first fixing member 43 is also included. The first fixing member 43 is connected to one end of the eccentric component housing 41 near the bearing 42, and is used to fix the bearing 42 inside the eccentric component housing 41. With the above structure, the first fixing member 43 can further fix the bearing 42, preventing the eccentric component 20 and the image acquisition device 30 from detaching from the eccentric component housing 41, thus improving the stability of the product.

[0062] In this embodiment, the inner wall of the eccentric component housing 41 is provided with a limiting boss 411, which abuts against the bearing 42 to fix the bearing 42 between the limiting boss 411 and the first fixing member 43. With the above structure, both ends of the bearing 42 abut against the limiting boss 411 and the first fixing member 43 respectively, which further fixes the bearing 42, prevents the bearing 42 from moving axially, and improves the stability of the product.

[0063] In this embodiment, the housing 10 is provided with a lighting device 80 near the image acquisition window 12. The lighting device 80 is connected to the first control board 51 through a third electrical connection line 52. The lighting direction of the lighting device 80 matches the orientation of the image acquisition device 30. Through the above-described structure, the lighting device 80 can provide illumination, making the images acquired by the image acquisition device 30 clearer, allowing users to better understand the situation inside the pipe, and making it more convenient to use. Furthermore, the lighting direction of the lighting device 80 matches the orientation of the image acquisition device 30, effectively illuminating the environment in front of the image acquisition device 30, improving the efficiency and clarity of the images acquired by the image acquisition device 30. The first control board 51 can control the lighting device 80 according to user instructions, such as turning on or off some of the LED beads 81, or adjusting the brightness of the LED beads 81. When there is insufficient light inside the pipe, it can effectively supplement the illumination, while when there is sufficient light inside the pipe, it can turn off some of the LED beads to save energy. At the same time, adjusting the light intensity can also change the ambient brightness, preventing excessive brightness from causing overexposure of the images acquired by the image acquisition device 30, ensuring the clarity of the images acquired by the image acquisition device 30, and further helping users understand the situation inside the pipe.

[0064] In this embodiment, the lighting device 80 includes a plurality of LED beads 81. The housing 10 has an LED bead slot 13 surrounding the image acquisition window 12, and the LED beads 81 are disposed within the LED bead slot 13. The LED beads 81, disposed within the LED bead slot 13 and surrounding the image acquisition window 12, can make the light around the image acquisition window 12 more uniform, thereby making the ambient light in front of the image acquisition device 30 more uniform, resulting in a clearer image acquired by the image acquisition device 30, and preventing localized excessively dark or bright light from affecting image clarity.

[0065] In this embodiment, the lighting device 80 further includes a lampshade 82, which is connected to the housing 10 and covers the lamp bead slot 13 and the image acquisition window 12. The lampshade 82 can effectively isolate the lamp bead 81 and the image acquisition device 30 from the external environment, improve the product's sealing performance, prevent debris in the pipes from damaging the lamp bead 81 and the image acquisition device 30, and extend the product's service life. Preferably, the lampshade 82 is made of transparent, high-strength glass, plastic, or resin, etc.

[0066] In this embodiment, the outer surface of the eccentric housing 41 is provided with a wiring groove 412. The third electrical connection wire 52 passes through the wiring groove 412 and is accommodated between the wiring groove 412 and the inner wall of the housing 10. With the above structure, the wiring groove 412 can effectively accommodate the third electrical connection wire 52, ensuring the stability of the electrical connection between the first control board 51 and the lighting device 80; at the same time, it also facilitates the user to insert the eccentric housing 41 into the receiving cavity 11, preventing the third electrical connection wire 52 from obstructing the insertion of the eccentric housing 41 during assembly, thereby improving the assembly and production efficiency of the product.

[0067] In this embodiment, a second fixing member 60 is also included. The second fixing member 60 is connected to the inner wall of the receiving cavity 11 and abuts against the first control plate 51, so that the first control plate 51 is confined between the first fixing member 43 and the second fixing member 60. With the above structure, the second fixing member 60 and the first fixing member 43 fix the first control plate 51, further improving the stability of the product and preventing the first control plate 51 from moving within the receiving cavity 11. Preferably, the second fixing member 60 is threaded to the inner wall of the receiving cavity 11 through a threaded portion, improving the stability of the connection.

[0068] This embodiment also includes a connecting handle 70, which has a first connecting end 71 and a second connecting end 72. The first connecting end 71 is connected to the end of the housing 10 away from the image acquisition device 30, and the second connecting end 72 is used to connect to the connecting wire and the cable 18 of the detection system. The first connecting end 71, connected to the end of the housing 10 away from the image acquisition device 30, can cover the receiving cavity 11, making the receiving cavity 11 a sealed space, protecting the image acquisition device 30, the second control board 32, and the first control board 51 and other components inside the receiving cavity 11, preventing these components from being contaminated by impurities in the pipe, and improving the stability of the product. The second connecting end 72 is connected to the connecting wire, which can realize the transmission of electrical signals. When the connecting wire is inserted into the pipe, the endoscope probe can be inserted deeper into the pipe along with the connecting wire, making it convenient for users.

[0069] In this embodiment, the outer surface of the first connecting end 71 is provided with a first external thread 711, and the end of the receiving cavity 11 away from the image acquisition device 30 is provided with a first internal thread 111. The first external thread 711 is threadedly connected to the first internal thread 111. With the above-mentioned structure, the first internal thread 111 and the first external thread 711 cooperate to effectively improve the stability of the connection between the first connecting end 71 and the housing 10, prevent the endoscope probe from disengaging when it is inserted deep into the pipe, and effectively protect the user's property safety.

[0070] In this embodiment, a sealing ring 90 is also included. A sealing groove 712 is provided on the outer surface of the first connecting end 71, and the sealing ring 90 is disposed within the sealing groove 712. When the first external thread 711 is threadedly connected to the first internal thread 111, the sealing ring 90 abuts against the inner wall of the receiving cavity 11 and the inner wall of the sealing groove 712. Through the above structural arrangement, the sealing ring 90 abutting against the inner wall of the receiving cavity 11 and the inner wall of the sealing groove 712 can further improve the sealing performance between the housing 10 and the first connecting end 71, preventing the components inside the receiving cavity from being contaminated by impurities in the pipeline.

[0071] In this embodiment, the connecting handle 70 includes a spring 73 located between the first connecting end 71 and the second connecting end 72. The spring 73 is deformable under the action of the inner wall of the pipe. With the above-described structure, during use, the endoscope probe is inserted into the pipe. Due to the complex environment inside the pipe, the deformable spring 73 can improve the adaptability of the product, allowing it to still be inserted into the pipe even in complex environments.

[0072] In this embodiment, the spring 73 gradually tapers from the first connecting end 71 to the second connecting end 72. Through this structural arrangement, the spring 73 is tapered, and its performance adapts to changes in load, effectively reducing impact and vibration caused by load variations, improving system stability and reliability, and ensuring the stability of images acquired by the image acquisition device 30. The housing is cylindrical with an outer diameter of 20mm-25mm and a length of 40mm-45mm. This size housing can accommodate smaller inner diameter sewers. The spring is 90mm-95mm long, with the thicker end having a diameter of 18mm-22mm and the thinner end having a diameter of 15mm-17mm. The longer spring can accommodate narrower pipes with more bends, allowing for easier deformation and insertion into the pipe, facilitating probe use and improving the user experience. Furthermore, the second connecting end is 28mm-32mm long, allowing for easy connection of wires and extending into the pipe along with the spring.

[0073] In this embodiment, the endoscopic probe further includes a fourth electrical connection wire 54. The fourth electrical connection wire 54 passes through the first connection end 71 and the spring 73 and connects to the second connection end 72. The fourth electrical connection wire 54 passes along the middle of the first connection end 71 and the spring 73, ensuring the stability of the electrical connection. The spring 73 and the first connection end 71 also provide protection for the fourth electrical connection wire 54, ensuring the stability of the product.

[0074] In this embodiment, the pipe endoscope probe also includes a first connector 722 for fixed connection with the cable 18 of the detection system. The first connector 722 is detachably electrically connected to the second connector 72. The first connector 722 makes it easier for users to connect the pipe endoscope probe and the detection system.

[0075] In this embodiment, the first implementation of the first connector 722 structure includes a fixing cover 722-1A and a conductive plate 722-1B. A plurality of elastic charging pins 721 are provided on the second connection end 72. The conductive plate 722-1B is installed inside the fixing cover 722-1A. The cable 18 passes through the fixing cover 722-1A and is electrically connected to the conductive plate 722-1B. The fixing cover 722-1A is detachably and fixedly installed on the second connection end 72. When the fixing cover 722-1A is fixedly installed on the second connection end 72, the... The conductive plate 722-1B presses against the elastic charging pin 721. The conductive plate 722-1B, the fixed cover, and the elastic charging pin 721 are designed to facilitate users in quickly and easily connecting the endoscope probe to the detection system. The connection method between the elastic charging pin 721 and the conductive plate 722-1B makes assembly easier for manufacturers, and also facilitates user disassembly and replacement of these components, while enhancing safety. The fixed cover makes it easier for users to connect the conductive plate 722-1B to the elastic charging pin 721. This structure is very simple, with low manufacturing and replacement costs. The display can be electrically connected to the conductive plate 722-1B via wires. That is, if there are four elastic charging pins 721, the conductive plate 722-1B has four rings of electrical contact areas on the side opposite the elastic charging pins 721, and these four rings are not interconnected. Figure 2 The conductive plate 722-1B shown has a structure on one side opposite the elastic charging pin 721. On the side of the conductive plate 722-1B away from the elastic charging pin 721, there are also four non-connected electrical contact areas corresponding to the four-ring electrical contact areas, as shown below. Figure 5 The structure of the conductive plate 722-1B away from the elastic charging pin 721 is used to connect to the four wires 722-1C respectively. An opening 722-1D can be made in the upper part of the fixing cover 722-1A for the four wires 722-1C to pass through. It should be noted that the opening 722-1D should be waterproof to prevent water from leaking into the fixing cover 722-1A and damaging the conductive plate 722-1B.

[0076] Further, the conductive plate 722-1B includes a circuit board 722H, a plurality of first electrodes 722M disposed on a first surface of the circuit board 722H, and a plurality of second electrodes 722N disposed on a second surface of the circuit board 722H away from the first surface. The plurality of first electrodes 722M and the plurality of second electrodes 722N are electrically connected via the circuit board 722H. It can be understood that the plurality of first electrodes 722M are used to abut and electrically connect with the plurality of elastic charging pins 721 in a one-to-one correspondence. The plurality of second electrodes 722N are electrically connected to the plurality of wires 722-1C respectively. The four wires 722-1C extend through the opening 722-1D and can be connected to an image receiving device (such as a display 15) via a cable 18. Figure 2 and Figure 5 As shown, the multiple first electrodes 722M are all ring electrodes, and the multiple first electrodes 722M are arranged alternately from the inside to the outside. The multiple second electrodes 722N are point electrodes, respectively disposed on four different sides of the second surface.

[0077] It is understandable that since the multiple first electrodes 722M are ring electrodes, even if the position of the elastic charging pin 721 changes due to connection or rotation, it can still maintain electrical contact with the ring electrode, thereby improving the stability of the electrical connection between the two and thus improving the reliability of the product.

[0078] Furthermore, the multiple second electrodes 722N on the four sides are point electrodes, which also makes the lengths of the multiple wires 722-1C basically the same, the impedance average, and the force uniform, thus making the transmission signal of the four wires 722-1C more stable and improving the reliability of the product.

[0079] In this embodiment, the second implementation of the structure of the first connector 722 is as follows: Figure 13-15 As shown, the first connector 722 includes an electrical connector 722-2, and the second connector 72 is provided with an electrical pin 721-2. The electrical connector 722-2 has an electrical socket 7220, and the electrical pin 721-2 is inserted into the electrical socket 7220. The second connector 72 is electrically connected to the electrical connector 722-2, that is, the electrical connection is made by plugging in, which makes the electrical connection more convenient and faster.

[0080] Furthermore, such as Figure 13-15As shown, in this embodiment, the first connector further includes a connecting cover 722-3, which is movably disposed on the electrical connector 722-2. The electrical pin 721-2 has a surrounding wall 7210. The outer surface of the surrounding wall 7210 of the electrical pin 721-2 is provided with a second external thread 7211, and the inner wall of the connecting cover 722-3 is provided with a second internal thread 72230. After the electrical pin 721-2 is inserted into the electrical socket 7220, the surrounding wall 7210 of the electrical pin 721-2 covers the outer side of the electrical connector 722-2. The second connecting end 72 is fixedly installed on the electrical connector 722-2 through the connection of the second internal thread 72230 and the second external thread 7211. The connecting cover 722-3 locks the second connecting end 72 and the electrical connector 722-2, which achieves waterproofing, fastening, and easy disassembly and assembly. The structure is simple, cost-saving, and user-friendly.

[0081] In this embodiment, the rotatable component 402 includes a cable organizer 4021, and the fixed component 401 includes a cable harness 4011. The cable organizer 4021 is electrically connected to the cable harness 4011, and the cable organizer 4021 can rotate relative to the cable harness 4011. With the above structure, during use, while the cable organizer 4021 rotates relative to the cable harness 4011, the cable organizer 4021 and the cable harness 4011 remain electrically connected, avoiding entanglement between the second electrical connection wire 404 electrically connected to the cable organizer 4021 and the second electrical connection wire 404 electrically connected to the cable harness 4011 during rotation.

[0082] In this embodiment, the cable organizer 4021 includes multiple conductive rings 4022, and the cable harness 4011 includes multiple conductive contacts 4012. The outer side of the conductive ring 4022 abuts against the conductive contacts 4012 to maintain the electrical connection between the cable organizer 4021 and the cable harness 4011. With the above structure, in use, the outer side of the conductive ring 4022 is recessed inward, and the conductive contacts 4012 have a certain elastic force. When the outer side of the conductive ring 4022 abuts against the conductive contacts 4012, the outer side of the conductive ring 4022 and the conductive contacts 4012 are firmly locked in the recessed position of the outer side of the conductive ring 4022. The conductive contacts 4012 undergo a certain elastic deformation, so that the abutment point between the outer side of the conductive ring 4022 and the conductive contacts 4012 has a certain abutting force, so that the abutment state can still be maintained when the outer side of the conductive ring 4022 and the conductive contacts 4012 rotate relative to each other, thereby ensuring the stability of the electrical connection.

[0083] In this embodiment, the pipe endoscope probe 1000 further includes a fixing component 401. The wire harness 4011 includes a first wire harness unit 40111 and a second wire harness unit 40112. The conductive contact 4012 is disposed inside the first wire harness unit 40111 and the second wire harness unit 40112. The fixing component 401 is used to restrict the radial movement of the first wire harness unit 40111 and the second wire harness unit 40112, so that the outer side of the conductive ring 4022 and the conductive contact 4012 remain in contact. With the above-described structure, during use, the first wire harness unit 40111 and the second wire harness unit 40112 engage, and a portion of the shaft of the wire organizer 4021, including the conductive contact 4012, is wrapped around the inner sides of the first wire harness unit 40111 and the second wire harness unit 40112, ensuring that the conductive contact 4012 is in contact with the outer side of the conductive ring 4022. Because there is elasticity between the conductive contact 4012 and the outer side of the conductive ring 4022 when the conductive contact 4012 is in contact with the outer side of the conductive ring 4022,... The force causes the engaged first wire harness unit 40111 and second wire harness unit 40112 to tend to separate radially. Therefore, the fixing component 40 is provided to limit the radial movement of the first wire harness unit 40111 and second wire harness unit 40112, while neutralizing the elastic force on the first wire harness unit 40111 and second wire harness unit 40112. This allows the conductive contact 4012 to maintain stable contact with the outer side of the conductive ring 4022, improving the stability of the electrical connection and further enhancing the user experience.

[0084] like Figure 18-19 As shown, this embodiment also includes a detection system for displaying images detected by the endoscope probe 1000. The detection system includes a display 15 for displaying images detected by the endoscope probe 1000; and a cable 18, one end of which is electrically connected to the display 15, and the other end of which is electrically connected to a first connector 722 of the endoscope probe, so that the cable 18 is electrically connected to the endoscope probe 1000 and transmits the detected images to the display 15. Those skilled in the art will understand that the display 15 can be a display dedicated to this detection system. In some embodiments, the display 15 can also be other devices with display functions. For example, the display 15 can be a mobile terminal such as a mobile phone or tablet, or a computer device such as a laptop or desktop computer. The cable 18 is configured to connect the endoscope probe 1000 and the display 15 together to transmit detection data to the display 15. In some embodiments, the cable 18 can also be configured to provide power to the endoscope probe 1000.

[0085] In this embodiment, the detection system also includes a winding frame 19 for the cable 18 to be wound around. The winding frame 19 includes a main support frame 191 and a rotating bracket 192. The rotating bracket 192 is rotatably mounted on the main support frame 191. The cable 18 is wound around the rotating bracket 192 so that the cable 18 can be wound up and down by rotating the rotating bracket 192. The cable 30 can be wound around the winding frame 19 so that the cable 18 can be wound up and down according to the operation requirements of the pipe endoscope probe 1000, thereby controlling the length of the released cable 18.

[0086] In this embodiment, the detection system further includes a signal connector 193, a second connector 194, and a fifth electrical connection line 195. The signal connector 193 receives signals emitted by the endoscope probe 1000 to determine the position of the endoscope probe 1000. The signal connector 193 can receive signals using methods such as WiFi, AM, FM, etc., which are not limited in this application. The signal connector 193 is mounted on the rotating bracket 192. One end of the fifth electrical connection line 195 is connected to the display, and the other end of the fifth electrical connection line 195 is connected to the second connector 194. The second connector 194 is detachably connected to the signal connector 193. The cable 18 is electrically connected to the signal connector 193. The detachable connection of the second connector 194 and the signal connector 193 facilitates signal connection and disconnection for the user, meeting the user's signal needs. Furthermore, in unpredictable situations, it allows for easy power disconnection from the endoscope probe 1000.

[0087] Furthermore, the rotating bracket 192 includes a central shaft 1921 and several frame shafts 1922. The several frame shafts 1922 are arranged around the central shaft 1921. The center of both the central shaft 1921 and the frame shafts 1922 are hollow, and the central shaft 1921 and the frame shafts 1922 are interconnected. A through hole 1923 is provided on one of the frame shafts 1922. One end of the fifth electrical connection line 195, which is electrically connected to the display 15, passes through the through hole, passes through the interior of the frame shafts 1922 and the central shaft 1921, and exits the central shaft to connect with the display 15. The fifth electrical connection line 195 is essentially hidden. The concealment of the wire for the winding frame 19 makes it easier to transport the winding frame 19 and will not affect the cable laying process, making the overall detection system operate in an orderly and uncluttered manner.

[0088] like Figure 20 As shown, the tubular endoscope assembly provided in the first embodiment of this utility model includes a display 15 and a... Figures 1 to 17The illustrated endoscope probe is communicatively connected to the display 15 and used to transmit image signals to the display 15. Specifically, the endoscope probe can be electrically connected to the display 15 via a flexible electrical cable, the length of which is typically set as needed, through a controller 16. The image signals acquired by the endoscope probe are transmitted to the display 15 for image display via the controller 16. Due to the presence of the eccentric component 20, the endoscope probe always maintains a positive orientation when acquiring image signals, and the image displayed on the display 15 based on these image signals always remains positive. It can be understood that this positive orientation is a preset direction for user convenience, such as the direction of gravity.

[0089] like Figure 21 As shown in the second embodiment of the present invention, the endoscope assembly is provided. In this embodiment, the driving / adjusting device includes a controller 16 and a driving connector 17. The controller 16 is electrically connected to the first control board 51. The driving connector 17 is fixedly mounted on the image acquisition device 30 and electrically connected to the image acquisition device 30. The controller 16 controls the driving connector 17 to drive the image acquisition device 30 to rotate, generating a driving signal. Based on the image acquired by the image acquisition device 30 displayed on the display 15, the controller 16 and the driving signal ensure that the image acquired by the image acquisition device 30 is always in the positive orientation. The driving connector 17 is mounted on the image acquisition device 30, and the controller can drive the driving connector 17 to drive the image acquisition device 30. The controller 16 includes a driving button and a driving device, meaning that the user can press the driving button through the display 15 to control the driving connector 17 so that the image acquisition device 30 is in the positive orientation for acquisition.

[0090] Please see Figures 22-29 In the endoscopic probe, the second control board 32 and the first control board 51 also constitute a control board module for the endoscopic probe, used for communication connection with external devices and transmission of image signals to the external devices. Figure 20 As shown, the control module may include a main control chip 100 and multiple functional modules electrically connected to the main control chip 100. The multiple functional modules include a power module 101, a storage module 102, a flash memory module 103, a switch control module 104, an infrared illumination module 105, an infrared control module 106, and an image module 107.

[0091] Specifically, the main control chip 100 and the aforementioned multiple functional modules can be respectively disposed on the second control board 32 and the first control board 51 as needed. Furthermore, in other embodiments, the second control board 32 and the first control board 51 can be combined into one, so that the main control chip 100 and the multiple functional modules can all be disposed on it. In this embodiment, the storage module 102 can be disposed on the second control board 32, while the other modules are disposed on the first control board 51.

[0092] Please see Figure 23 The power module 101 includes a main power chip U2, a voltage regulator chip U1, a power signal input terminal 1011, and a power signal output terminal 1012. The power signal input terminal 1011 is used to receive a first power supply voltage. The main power chip U2 is used to control the conversion of the first power supply voltage into a conversion voltage. The conversion voltage is further processed by diode D1 and the voltage regulator chip U3 into a stable second power supply voltage, which is then used to power the storage module 102, the flash memory module 103, the switch control module 104, etc.

[0093] like Figure 24 As shown, the power supply pin VCC, clock signal pin SCL, and data pin SDA of the storage control chip U3 of the storage module 102 are all electrically connected to the main control chip U1. The storage module 102 is used to temporarily store the image signals acquired by the lens 31.

[0094] like Figure 25 As shown, the sampling pin CSB, input pin MIS0, output pin MOS1, and clock pin of the flash memory control chip U6 of the flash memory module 103 are all electrically connected to the main control chip. The flash memory module 103 is used for data storage when power is off.

[0095] like Figure 26 As shown, the signal transmission terminal VP and the image output terminal VODEO OUT of the switch control module 104 are both electrically connected to the main control chip 100. The signal transmission terminal VP and the image output terminal VODEO OUT are grounded via multiple switch branches 1041. Each switch branch 1041 includes a resistor 1042 and a control switch 1043 connected in series. Each switch branch 1041 is used to control the on / off state of switches, lighting, and other functions based on commands generated for operation.

[0096] like Figure 27As shown, the infrared illumination module 105 includes a transistor Q2 and a light-emitting element D6. The control terminal of the transistor Q2 is electrically connected to the main control chip 100, the first conducting terminal of the transistor Q2 is electrically connected to the power supply module 101, and the second conducting terminal of the transistor Q2 is grounded via the light-emitting element D6. The light-emitting element D6 can be turned on under the control of the main control chip 100 to emit infrared light, enabling the lens 31 to acquire images in dark environments.

[0097] like Figure 28 As shown, the infrared control module 106 includes an infrared filter control chip U4, which is an IR-CUT dual filter control chip used to control the operation of the infrared dual filters in the lens 31. Specifically, the infrared filter control chip U4 controls the infrared dual filters in the lens 31 to automatically switch filters according to the intensity of external light after the infrared sensing point outside the lens 31 detects a change in light intensity, so that the image achieves the best effect. That is to say, the infrared dual filters in the lens 31 can automatically switch filters in daylight or darkness, so the lens 31 can obtain the best imaging effect regardless of whether it is day or night.

[0098] like Figure 29 As shown, the image module 107 is electrically connected to the lens 31 and the main control chip 100, respectively.
