[0001] The present invention belongs to the technical field of optical detection, and particularly relates to an optical system, a control method thereof, and a cabin body. Background Art

[0002] With the rapid development of various aircraft and surface vessels, the optical systems carried by them play a key role in scenarios such as environmental monitoring, navigation and obstacle avoidance, and target recognition.

[0003] According to actual functional requirements, traditional optical systems usually have two setting methods. One is to open small holes in the cabin body for installing components such as lenses, and a strengthened glass is provided corresponding to the holes. While protecting the lens, the flatness of the outer peripheral wall of the cabin body can be maintained. However, this setting method limits the detection range of the optical system; the other is to set a protective cover outside the cabin body, and the optical system is arranged therein, and its lens can also rotate therein, so as to obtain a larger detection range. However, this setting method will affect the external shape design of the cabin body, and then increase the motion resistance of the aircraft or vessel.

[0004] Therefore, there is currently a need for an optical system applied to an aircraft or vessel to perform a larger range of optical detection without affecting its external shape design. Summary of the Invention

[0005] In view of one or more of the above defects or improvement requirements of the prior art, the present invention provides an optical system, a control method thereof, and a cabin body, which can perform a larger range of optical detection without affecting the external shape design of the cabin body.

[0006] To achieve the above object, the present invention provides an optical system, which includes a base and an optical component disposed in the base. The base includes a cylinder and a seat body disposed at one end of the cylinder, and the optical component includes a lens barrel. The cylinder is provided with a first through hole penetrating through both ends thereof, the lens barrel is accommodated in the first through hole, and the lens barrel is coaxially disposed with the cylinder. A seal is provided between the inner wall surface of the cylinder and the outer wall surface of the lens barrel. The seat body is internally provided with a sliding seat slidably connected to the seat body and a driving mechanism for driving the sliding seat to move. The sliding seat is connected to the lens barrel to drive the lens barrel to reciprocate along its axis.

[0007] As a further improvement of the present invention, the first through hole is a stepped hole, which includes a large-diameter section and a small-diameter section.

Through the sliding connection between the slide rail and the slide groove, the relative position sliding between the seat body and the sliding plate is realized.

[0012] As a further improvement of the present invention, an electrical signal processing module is provided on the side of the optical component away from the lens barrel. The electrical signal processing module is fixedly connected to the base and is electrically connected to the optical component for processing electrical signals; and / or, A control module is further provided in the base.

[0024] Embodiment: Please refer to Figures 1 to 10 In a preferred embodiment of the present invention, the optical system includes a base 1 and an optical component 2 disposed in the base 1. Among them, the base 1 includes a first cylinder 101 and a seat body 102 disposed at one end of the first cylinder 101. The first cylinder 101 is provided with a first through hole penetrating through its two end faces. The optical component 2 includes a lens barrel 202, which can be accommodated in the first cylinder 101, and the lens barrel 202 is coaxially arranged with the first cylinder 101. The lens barrel 202 includes a second cylinder and an optical lens disposed in the second cylinder. The optical lens is disposed at one end of the second cylinder away from the seat body 102. The lens barrel 202 and the first cylinder 101 can perform relative reciprocating motion in the axial direction, so that the optical lens can extend out of the first cylinder 101 or be retracted into the first cylinder 101. Further, since the first cylinder 101 and the second cylinder are coaxially arranged, the axial directions of the two are the same direction, that is, the first direction. The direction perpendicular to the bottom plate of the seat body 102 is the second direction, and the direction perpendicular to the first direction and the second direction respectively is the third direction.

[0025] Further, a sliding seat 201 slidably connected to the seat body 102 is provided inside the seat body 102, and a driving mechanism 8 capable of driving the sliding seat 201 to move is also provided inside the seat body 102. The sliding seat 201 is further connected to the lens barrel 202, so that the driving mechanism 8 can drive the lens barrel 202 to perform reciprocating motion along its axis through the sliding seat 201. Further preferably, the optical lens is provided on the side wall surface of the second cylinder, and the optical lens can also be a plurality of lenses arranged at intervals along the circumferential direction of the second cylinder.

[0026] Further, a seal 6 is provided between the inner wall surface of the first cylinder 101 and the outer wall surface of the second cylinder, for sealing the gap between the first cylinder 101 and the second cylinder, so as to isolate the internal space of the seat body 102 from the external space, thereby protecting the related equipment inside the seat body 102.

[0027] In one embodiment, an annular groove is formed on the inner circumferential wall surface of the first cylinder 101, and the seal 6 is an annular sealing ring embedded in the annular groove. The inner wall surface of the sealing ring is in close contact with the second cylinder to achieve sealing. Further, the annular grooves are a plurality of annular grooves arranged at intervals in a first direction, and the shapes of the sealing rings are the same, and can also play a supporting role for the lens barrel 202.

[0028] In another embodiment, the first through hole inside the first cylinder 101 is a stepped hole, which includes a large-diameter section and a small-diameter section. Among them, the large-diameter section is close to the seat body 102, and the small-diameter section is arranged at one end of the large-diameter section away from the seat body 102. The seal 6 is also arranged on the step surface. A limiting member 4 is further arranged on the side of the seal 6 away from the step surface, for limiting the seal 6. According to actual needs, a combination of the seal 6 and the limiting member 4 can be additionally arranged on the side of the limiting member 4 away from the seal 6 to further enhance the sealing performance. The inner circumferential wall surface of the small-diameter section is in fit with the outer circumferential wall surface of the second cylinder to achieve the support of the lens barrel 202.

[0029] Further, a certain gap still remains between the inner circumferential wall surface of the small-diameter section and the outer circumferential wall surface of the lens barrel 202. A groove is formed on the inner wall surface of the small-diameter section, and a guiding member 5 is correspondingly arranged in the groove. The surface of the guiding member 5 away from the groove body abuts against the outer wall surface of the lens barrel 202 to achieve radial limiting and support of the lens barrel 202. Further preferably, the grooves are a plurality of grooves arranged at intervals along the circumferential direction, or the grooves are annular grooves, and the guiding member 5 is correspondingly arranged as a guiding ring structure. The material of the guiding member 5 is a composite material, preferably a carbon fiber composite material, which has a low friction coefficient to facilitate the reciprocating motion of the lens barrel 202, and can withstand high temperatures and low temperatures at the same time to adapt to the high temperature or low temperature scenarios on the outer surface of the cabin.

[0030] Further, the large-diameter section in the stepped hole can be further set in the form of a stepped hole, which includes a first diameter section and a second diameter section. Among them, the inner diameter of the first diameter section is smaller than that of the second diameter section, so that the entire first through hole has two stepped surfaces. The stepped surface formed between the large-diameter section and the small-diameter section is the first stepped surface, and the stepped surface formed between the first diameter section and the second diameter section is the second stepped surface. The seal 6 is correspondingly arranged on the first stepped surface, and the limiting member 4 is arranged on the second stepped surface to limit the seal 6. Through this setting method, the staff can install the seal 6 and the limiting member 4 in sequence along the first direction. Further preferably, the seal 6 is a pantograph seal, and the limiting member 4 is a threaded retainer ring. The inner diameter of the pantograph seal does not change without force, so that the lens barrel 202 can move unobstructed. Under high-temperature and high-pressure working conditions, its inner diameter shrinks, thereby realizing the seal between the lens barrel 202 and the first cylinder 101.

[0031] Further, the top plate 104 of the seat body 102 and the panel 103 away from the first cylinder 101 are detachably connected to the seat body 102, so that after the internal equipment of the seat body 102 is installed, the plate member can be installed on the seat body 102. Further preferably, an electromagnetic shielding strip 12 is provided between the joint of the top plate 104 and the seat body 102 and the joint of the panel 103 and the seat body 102, which is used to realize electromagnetic isolation between the inside of the base 1 and the outside world and prevent the electrical components inside the base 1 from being interfered.

[0032] Further, the sliding seat 201 includes a sliding plate 2011 and a frame body 2012 arranged on the sliding plate 2011. Among them, the sliding plate 2011 is slidably connected to the bottom plate of the seat body 102, and the frame body 2012 is arranged opposite to the lens barrel 202 and fixedly connected to the lens barrel 202. Further preferably, a positioning pin 204 and bolts are provided between the frame body 2012 and the sliding plate 2011 to determine and fixedly connect the relative positions between the frame body 2012 and the sliding plate 2011.

[0033] Further, a first mounting plate 2013 is arranged on the side of the frame body 2012 opposite to the lens barrel 202. Correspondingly, the lens barrel 202 is also provided with a second mounting plate. The first mounting plate 2013 and the second mounting plate are arranged opposite to each other and fixedly connected by a pin body 205. Multiple brackets extending along the first direction can also be arranged on the frame body 2012 to increase the overall length of the optical assembly 2, so that the end face of the lens away from the seat body 102 is flush with the end face of the first cylinder 101. Further illustrated, the inner diameter of the second diameter section can be further enlarged so that the mounting plate can enter the large-diameter section.

[0034] Furthermore, the optical component 2 further includes a photoelectric conversion module 203 disposed inside the housing 2012. The photoelectric conversion module 203 is connected to the lens barrel 202, so that the optical information collected by the lens barrel 202 is directly sent to the photoelectric conversion module 203, and the photoelectric conversion module 203 can move along with the movement of the sliding seat 201, thereby realizing the reciprocating movement of the optical component 2 in the first direction. Further preferably, a third cylinder is disposed between the lens barrel 202 and the photoelectric conversion module 203. The third cylinder is respectively connected to the lens barrel 202 and the photoelectric conversion module 203. An optical fiber is disposed inside the third cylinder, so that the optical signal is transmitted to the photoelectric conversion module 203. A support frame 206 is provided corresponding to the third cylinder. One end of the support frame 206 close to the third cylinder is an arc structure matching the third cylinder, which is used to support the third cylinder. A pressing member 207 is further provided corresponding to the support frame 206. One end of the pressing member 207 close to the third cylinder is also set as an arc structure matching the third cylinder, and the pressing member 207 is fixedly connected to the support frame 206 to realize the stable support of the third cylinder, and further realize the auxiliary support of the entire optical component 2 to ensure the overall stability of the optical component 2.

[0035] Furthermore, a slide rail 7 is provided on the bottom plate of the seat body 102. Oppositely, a chute matching the slide rail 7 is provided on the surface of the sliding plate 2011 aligned with the bottom plate, so that the sliding plate 2011 can move relative to the slide rail 7. The slide rail 7 and the chute are preferably in a "T" - shaped match. Further preferably, the slide rail 7 is detachably connected to the bottom plate. A plurality of connection positions are provided on the bottom plate, so that the slide rail 7 can be selected in position to adapt to different sliding seats 201 and / or seat bodies 102. At the same time, the slide rail 7 and the bottom plate are connected by bolts, and screw holes are correspondingly provided on the slide rail 7, so that the head of the bolt structure is not higher than the surface of the slide rail 7 after installation.

[0036] Furthermore, the driving mechanism 8 provided corresponding to the sliding seat 201 is disposed inside the seat body 102, and it is disposed on either side in the third direction of the sliding seat 201. The driving mechanism 8 includes a driving motor, a lead screw, and a slider sleeved on the lead screw. The movable end of the driving motor is fixedly connected to one end of the lead screw to drive the lead screw to rotate, and then drive the slider to reciprocate in the first direction. A connecting plate is provided between the slider and the sliding plate 2011 to realize the fixed connection between the slider and the sliding seat 201, so as to drive the sliding seat 201 to reciprocate in the first direction through the slider. Further preferably, the connecting plate is a trapezoidal structure, its short side is fixedly connected to the slider, and its long side is fixedly connected to the sliding plate 2011. While ensuring the structural stability, the structural size of the slider can be set to a smaller size, so as to extend the moving range of the slider as much as possible under the condition that the overall length of the lead screw is determined, thereby expanding the moving distance of the sliding seat 201.

[0037] Further, a motor base and a lead screw base are respectively provided corresponding to the drive motor and the lead screw, for realizing the fixed connection between the two and the base 1. Further, in order to achieve a compact design, the drive motor is arranged above the lead screw, and a gear is provided at the movable end of the drive motor. Correspondingly, a gear is also provided at one end of the lead screw. The drive motor drives the lead screw through the meshing of the gears. The motor base is fixedly connected to the drive motor, and the rotating part (i.e., the meshing gears) between the drive motor and the lead screw is accommodated therein to protect the structural members. The lead screw base is provided with two bearings at both ends of the lead screw respectively for supporting the lead screw.

[0038] Further, an electrical signal processing module 3 is also provided on the side of the sliding seat 201 away from the lens barrel 202. The electrical signal processing module 3 is fixedly connected to the panel 103, so that the electrical signal processing module 3 is fixedly connected to the base 1. At the same time, the electrical signal processing module 3 is electrically connected to the photoelectric conversion module 203, for receiving the electrical signal converted from the optical signal by the photoelectric conversion module 203 and processing the electrical signal.

[0039] Further, the electrical signal processing module 3 includes a power supply board 303, a heat dissipation board 301, and a signal processing board 304 arranged at intervals in sequence. Among them, the power supply board 303 and the signal processing board 304 are respectively fixedly connected to the heat dissipation board 301, and spacer posts 302 are provided between the power supply board 303 and the heat dissipation board 301, and between the heat dissipation board 301 and the signal processing board 304, so as to ensure the distance between the power supply board 303 and the heat dissipation board 301, and between the signal processing board 304 and the heat dissipation board 301, thereby forming a space for installing various heat-generating devices. Further preferably, a heat-conducting boss is also provided between the heat-generating device and the heat dissipation board 301. The heat-conducting boss is fixedly connected to the heat dissipation board 301, and a heat-conducting material is coated at the gap between the heat-conducting boss and the heat-generating device to assist in heat dissipation. The heat-conducting material is preferably silicone grease. At the same time, vertical plates are provided on both sides of the heat dissipation board 301. The vertical plates are respectively fixedly connected to the heat dissipation board 301 and the panel 103, and then the heat dissipation board 301 is fixed on the panel 103, and the heat in the heat dissipation board 301 is conducted to the panel 103 and the base body 102, and dissipated through the base body 102, thereby improving the heat dissipation efficiency.

[0040] Further, a control module is also provided on the side of the sliding seat 201 away from the driving mechanism 8. The control module is electrically connected to the driving mechanism 8, the optical component 2, and the electrical signal processing module 3 respectively, and is used to control the operations of the driving mechanism 8, the optical component 2, and the electrical signal processing module 3. Meanwhile, a wire binding rack 9 is provided in the seat body 102 corresponding to the control module, and is used to fix the wires connecting functional modules such as the driving mechanism 8, the optical component 2, and the photoelectric conversion module 203 to the control module. Further preferably, the control module includes a driving mechanism controller 11 fixedly connected to the top plate 104, which is used to control the driving motor in the driving mechanism 8 to perform corresponding operations. Moreover, the control module further includes various plug-in connectors to realize the communication connection between the optical component 2 and the electrical signal processing module 3 and an external platform, and to transmit control signals and image information.

[0041] Further, the installation space of the control module can be a separately provided box body 105, rather than expanding the entire seat body 102, which may cause the problem of increasing the overall floor space of the base 1. Further preferably, a plurality of interfaces are correspondingly opened on the installation box body 105 for installing plug-in connectors.

[0042] Further, the control module further includes an integrated controller, which is electrically connected to the optical component 2, the electrical signal processing module 3, and the driving mechanism controller 11 respectively, and is connected to an external platform through a plug-in connector, so as to receive external platform signals and send them to each functional module for control, and send the collected image information to the external platform.

[0043] In practical applications, after receiving a motion instruction, the driving mechanism 8 will move the slider to a preset specified position. However, to avoid the situation where the slider is not in place or over-positioned, a position sensor is correspondingly provided for the driving mechanism 8 to detect whether the slider moves to the specified position. When the slider is in place, the position sensor sends an in-place signal to the control module, so that the driving mechanism 8 will not continue to move, thereby ensuring that the driving mechanism 8 will not push the slider out of position, increasing the safety redundancy. When the slider does not move to the specified position, the position sensor will also correspondingly send a not-in-place signal and the remaining distance to be advanced to the control module, so that the driving mechanism controller 11 controls the driving mechanism 8 to continue driving the slider to move until the slider is in place.

[0044] Further, a control method for an optical system is also proposed to realize the control of the optical system, which includes the following steps: S1. The staff sends a driving mechanism 8 motion and motion distance signal to the control module through an external platform. The control module controls the motion of the driving mechanism 8 through the driving mechanism controller 11 to drive the slider to move in a first direction, and then drives the lens barrel 202 to move away from one end of the seat body 102 until the optical lens extends out of the first cylinder body 101; After the optical lens moves to the specified position, the lens barrel starts the imaging work. The optical lens collects optical signals and transmits the optical signals to the photoelectric conversion module 203; After receiving the optical signal, the photoelectric conversion module 203 converts the optical signal into an electrical signal and transmits the electrical signal to the electrical signal processing module 3. The electrical signal processing module 3 modulates the electrical signal and sends the processed electrical signal to an external platform through the control module. The external platform generates an image based on the processed electrical signal; After the imaging work of the optical lens is completed, the external platform sends the movement distance information to the driving mechanism 8 through the control module to drive the lens barrel 202 to move towards one end close to the base body 102, so that the lens barrel 202 retracts into the first cylinder body 101.

[0045]

[0045] In step S1, the movement of the lens barrel 202 can be precisely controlled in various ways: Method 1: A position sensor is provided corresponding to the driving mechanism 8 to determine whether the optical component 2 slides to the specified position. When the optical component 2 moves to the specified position, the position sensor immediately sends the in-place information to the control module to ensure that the optical component 2 does not overshoot. Similarly, if the optical component 2 is not in place, the position sensor also sends relevant information to the control module, so that the driving mechanism 8 continues to drive the optical component 2 to move until it is in place; Method 2: The working modes of the optical component 2 and the electrical signal processing module 3 are turned on to obtain the image information collected by the optical lens. Whether the position of the optical lens satisfies the detection requirement is determined through the image information, and then it is determined whether the lens moves to the specified position.

[0046]

[0046] Furthermore, a cabin body is proposed. The cabin body can be applied to an aircraft, a surface vessel or a submersible. The cabin body includes a housing. A second through hole penetrating the inner and outer wall surfaces is provided on the housing, and the first cylinder body 101 is embedded in the second through hole. The base body 102 is correspondingly provided with lugs 10 and is fixedly connected to the inner wall surface of the housing through the lugs 10. Then, the optical system can extend the optical lens out of the cabin body or retract it into the cabin body. Further preferably, the end face of the lens barrel 202 away from the base body 102 is designed to be conformal with the outer wall surface of the cabin body, so that when the optical system is in the retracted state, it will not cause unevenness on the outer surface of the cabin body.
