Description

Technical Field

[0001] This application relates to the field of imaging technology, and more specifically, to a lens barrel structure and imaging device. Background Technology

[0002] The lens barrel is a common component in various optical and image acquisition devices. It is a specially designed cylindrical structure that holds the lens elements of a fixed lens and forms the corresponding optical path for imaging or image acquisition. Depending on the application, lens barrels can be divided into various types, such as photographic lens barrels and microscope barrels.

[0003] In photography, the length of a lens barrel varies depending on the lens's focal length. The distance required to adjust the focal length during focusing is related to the length of the optical path inside the lens barrel. Therefore, the length of the lens barrel is generally considered to be related to the focal length and the image quality at a given focal length. Currently, to reduce the size of imaging devices and increase the optical path length of the lens barrel to increase the focal length and thus optimize image quality, irregularly shaped lens barrel structures such as L-shaped ones are commonly used. However, these structures are difficult to design, require high material strength, and are complex to assemble. To maximize space utilization and obtain a longer physical optical path, the lens barrel can only be fixed at one end. When the lens barrel moves, it significantly affects the overall center of gravity of the imaging device. Furthermore, the optical path of the irregularly shaped lens barrel is still affected by its dimensions, resulting in poor extension of the optical path. Therefore, the existing irregularly shaped lens barrel structures are impractical and cannot meet current imaging and shooting needs. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a lens barrel structure and imaging device to improve the problem of poor practicality of the lens barrel structure in the prior art.

[0005] To address the aforementioned issues, in a first aspect, embodiments of this application provide a lens barrel structure, which includes: a lens barrel housing, an imaging sensor, a wide-angle sensor, and a reflector; The shooting sensor and the wide-angle sensor are disposed inside the lens barrel housing, and n reflectors are fixedly disposed inside the lens barrel housing; where n is a positive integer greater than or equal to 2; The reflector is used to reflect light entering the lens barrel housing, and the imaging sensor is used to receive the light reflected by the reflector for imaging processing; The wide-angle sensor is used to monitor the position of the target based on the received light.

[0006] In the above implementation process, multiple reflectors can be fixedly installed inside the lens barrel housing. Through the combination of multiple reflectors, combined with the shooting sensor and wide-angle sensor installed inside the lens barrel housing, the reflectors reflect the light entering the lens barrel housing, the shooting sensor receives the reflected light for imaging processing, and the wide-angle sensor detects the position of the shooting target based on the received light, realizing the dual-camera function of multiple reflections. While effectively extending the optical path length inside the lens barrel, it can also track and shoot the shooting target, effectively reducing the volume occupied by the lens barrel structure. Moreover, the lens barrel structure can be fixed as a whole on the external device, solving the problems of high assembly difficulty, unstable center of gravity, and poor optical path extension effect caused by irregular lens barrels. This improves the practicality of the lens barrel structure, making it suitable for a variety of different shooting scenarios and meeting the imaging needs of various shooting scenarios.

[0007] Optionally, the lens housing has a cylindrical structure.

[0008] In the above implementation process, the lens barrel housing is set as a straight cylindrical structure so that the lens barrel structure can be fixed as a whole on the external equipment, further reducing the disadvantage of unstable center of gravity caused by the irregular shape of the lens barrel structure when it moves, and improving the stability and movement accuracy of the lens barrel structure.

[0009] Optionally, n reflectors are disposed at the same end inside the lens barrel housing, and the n reflectors are combined to form a first type of reflection path, through which light enters the imaging sensor; wherein, the first type of reflection path includes a U-shaped reflection path.

[0010] In the above implementation process, in order to effectively extend the optical path length within the lens barrel structure, multiple reflectors can be set at the same end of the lens barrel housing to form a first type of reflection path with a U-shaped reflection path, so that light can enter the imaging sensor based on the first type of reflection path for the imaging sensor to perform imaging.

[0011] Optionally, n reflectors are disposed at both ends inside the lens barrel housing, and the n reflectors are combined to form a second type of reflection path, through which light enters the imaging sensor; wherein the second type of reflection path includes: a Z-shaped reflection path, a multi-Z-shaped combined reflection path, a multi-U-shaped combined reflection path, or a Z-shaped + U-shaped combined reflection path.

[0012] In the above implementation process, in order to effectively extend the optical path length within the lens barrel structure, multiple reflectors can be disposed at both ends of the lens barrel housing to form a Z-shaped reflection path (distributed at both ends), a multi-Z-shaped combined reflection path (distributed sequentially at both ends), a multi-U-shaped combined reflection path (a combination of multiple U-shaped reflection paths disposed at both ends), or a Z-shaped + U-shaped combined reflection path (a combination of Z-shaped and U-shaped reflection paths disposed at both ends) as a second reflection path, so that light can enter the imaging sensor based on the second type of reflection path for the imaging sensor to perform imaging.

[0013] Optionally, the end of the lens barrel housing is provided with a light inlet; The light inlet is fixedly equipped with a first type of lens corresponding to the shooting sensor and a second type of lens corresponding to the wide-angle sensor; The optical path area of ​​the first type of lens does not overlap with the area of ​​the reflector located near the end.

[0014] In the above implementation process, to allow light to enter the lens barrel, a light inlet can be provided at one end of the lens barrel housing. A first-type lens for the shooting sensor and a second-type lens for the wide-angle sensor are fixedly mounted on the light inlet, enabling independent operation of the two sensors in the dual-camera function. Furthermore, it should be noted that, considering that the reflector inside the lens barrel housing may be located near the light inlet, to reduce adverse light obstruction caused by the reflector, the optical path area of ​​the first-type lens does not overlap with the area of ​​the reflector near the end. The placement of the reflector, the first-type lens, and the lens aperture can be adjusted according to actual needs.

[0015] Optionally, the shooting sensor and the wide-angle sensor are disposed at the first end near the light inlet; Alternatively, the wide-angle sensor may be positioned at a first end near the light inlet, and the imaging sensor may be positioned at a second end away from the light inlet.

[0016] In the above implementation process, considering the different positions of the reflectors set inside the lens barrel structure, in order to enable normal light transmission, and considering that the optical paths of the wide-angle sensor and the imaging sensor are independent, the imaging sensor is provided with a longer imaging optical path by the reflectors, while the wide-angle sensor requires a shorter optical path. Therefore, the imaging sensor and the wide-angle sensor can both be set at the first end near the light entrance, or the wide-angle sensor can be set at the first end of the light entrance and the imaging sensor can be set at the second end away from the light entrance, so that the imaging sensor and the wide-angle sensor can be properly set inside the lens barrel structure and achieve normal imaging function.

[0017] Optionally, the lens barrel structure further includes: a focusing element; The focusing component is fixedly disposed inside the lens barrel housing, and the focusing component is connected to the shooting sensor; The focusing component is used to adjust the position of the imaging sensor in the optical path.

[0018] In the above implementation process, considering the need for focal length adjustment during shooting, the lens barrel structure may also include a focusing component fixedly installed inside the lens barrel housing. The focusing component is connected to the shooting sensor to adjust the position of the shooting sensor in its optical path, thereby realizing the focal length adjustment function and meeting the shooting needs of various different types of shooting targets in various different scenarios.

[0019] In a second aspect, embodiments of this application also provide an imaging device, the imaging device comprising: a driving structure and a lens barrel structure as described in any one of the first aspects above; The drive structure is connected to the lens barrel structure, and the drive structure is used to drive the lens barrel structure to move.

[0020] In the above implementation process, considering the movement requirements of tracking shooting, the imaging device may include a drive structure. The lens barrel structure is connected to the drive structure as a whole, and the drive structure drives the lens barrel structure to move. This effectively reduces the difficulty of assembling the lens barrel structure and improves the stability of the lens barrel structure when it moves. The lens barrel structure can also provide a longer optical path length, and obtain a larger focal ratio under the premise of a certain aperture. This effectively optimizes the shooting effect of the imaging device, is suitable for a variety of different shooting scenarios, and meets the imaging needs of a variety of different shooting scenarios.

[0021] Optionally, the driving structure includes: a first driving structure and a second driving structure; The first driving structure is connected to the outer wall of the lens barrel housing of the lens barrel structure; The second driving structure is connected to the first driving structure; The first motion axis of the first drive structure is parallel to the mounting surface of the imaging device, and the first drive structure is used to drive the lens barrel structure to rotate based on the first motion axis; The second drive structure has a second motion axis perpendicular to the mounting surface of the imaging device, and the second drive structure is used to drive the lens barrel structure to rotate based on the second motion axis.

[0022] In the above implementation process, to achieve automatic target tracking and imaging, the drive structure can be equipped with a first drive structure and a second drive structure to control the movement of the lens barrel structure in different directions. The first drive structure is connected to the outer wall of the lens barrel shell, and the second drive structure is connected to the first drive structure to control the synchronous movement of the lens barrel structure in two different axes: horizontal and vertical. The first drive structure can drive the lens barrel structure to rotate based on a first motion axis parallel to the mounting surface of the imaging device, and the second drive structure can drive the lens barrel structure to rotate based on a second motion axis perpendicular to the mounting surface of the imaging device. This enables movement control in both horizontal and vertical axes, effectively improving the efficiency and accuracy of the imaging device in automatic target tracking.

[0023] Optionally, the imaging device further includes: a controller and electrical connectors; The first driving structure is provided with a first through hole, and the cylindrical wall of the lens barrel housing is provided with a second through hole, with the first through hole and the second through hole being positioned corresponding to each other; The electrical connector passes through the first through hole and the second through hole, and the shooting sensor and wide-angle sensor disposed in the lens barrel structure are connected to the controller based on the electrical connector; The controller is used to receive and process the imaging data acquired by the shooting sensor and the wide-angle sensor.

[0024] In the above implementation process, for data transmission and processing, the imaging device can also include a sensor and an electrical connector for electrical connection. To house the electrical connector, a first through-hole is provided in the first drive structure, and a second through-hole is provided on the wall of the lens barrel housing. The first and second through-holes are positioned correspondingly, allowing the electrical connector to pass through both holes. This allows the electrical connector to connect the imaging sensor and wide-angle sensor located inside the lens barrel structure to a controller located outside the lens barrel structure, enabling the controller to receive and process the imaging data collected by the imaging sensor and wide-angle sensor. This allows the wiring to be routed within the internal space of the first drive structure, effectively reducing the space occupied by the electrical connector, meeting the miniaturization requirements of the imaging device, and realizing the corresponding data transmission and processing functions.

[0025] In summary, the embodiments of this application provide a lens barrel structure and imaging device. By combining multiple reflectors and integrating a shooting sensor and a wide-angle sensor, a dual-camera function with multiple reflections is achieved. This solves the problems of high assembly difficulty, unstable center of gravity, and poor optical path extension caused by irregularly shaped lens barrels, and meets various imaging needs.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

[0030] Currently, to reduce the size of imaging devices and increase the optical path length of the lens barrel to increase the focal length and thus optimize image quality, irregularly shaped lens barrel structures such as L-shaped ones are commonly used. However, this type of lens barrel structure has high structural design, material strength, and assembly difficulty. To maximize space utilization and obtain a longer physical optical path, the lens barrel device can only be fixed at one end. For example, one end of an L-shaped lens barrel structure is fixed to the imaging device, while the other end extends beyond the imaging device and cannot be fixed. In this case, if the unfixed end is long or heavy, it will significantly affect the overall center of gravity of the imaging device when the lens barrel moves, easily causing the device to tilt or fall over. Furthermore, the optical path of the irregularly shaped lens barrel structure is still affected by the irregular structural dimensions. For example, the optical path length of an L-shaped lens barrel structure is the same as the length of the L-shaped structure, resulting in poor extension of the optical path. Therefore, the existing irregularly shaped lens barrel structures have poor practicality and cannot meet current imaging and shooting needs.

[0031] To address the aforementioned issues, this application provides a lens barrel structure and imaging device. By combining multiple reflectors with a shooting sensor and a wide-angle sensor, a dual-camera function with multiple reflections is achieved. This solves problems such as high assembly difficulty, unstable center of gravity, and poor optical path extension caused by irregularly shaped lens barrels, thus meeting various imaging needs.

[0032] Please see Figure 1 , Figure 1 This is a schematic diagram of a lens barrel structure provided in an embodiment of this application. The lens barrel structure may include: a lens barrel housing 110, an imaging sensor 120, a wide-angle sensor 130, and a reflector 140.

[0033] Optionally, the lens housing 110 can be configured as a cylindrical or square structure with a cylindrical wall and two ends. The lens housing 110 can be made of metal or plastic depending on actual needs. For example, if there is a need for lightweight equipment, a plastic housing can be selected, and if there is a need for long-term outdoor use of equipment, a waterproof and sturdy metal housing can be selected.

[0034] The imaging sensor 120 and the wide-angle sensor 130 are disposed inside the lens barrel housing 110, and n reflectors 140 are fixedly disposed inside the lens barrel housing 110, where n is a positive integer greater than or equal to 2. The reflectors 140 are used to reflect light entering the lens barrel housing 110, and the imaging sensor 120 is used to receive the light reflected by the reflectors 140. Figure 1 (As shown by the dashed line) Imaging processing is performed, and the wide-angle sensor 130 is used to monitor the position of the target based on the received light. Multiple reflectors 140 can be fixedly installed inside the lens barrel housing 110. Through the combination of multiple reflectors 140, combined with the imaging sensor 120 and the wide-angle sensor 130 installed inside the lens barrel housing 110, the reflectors 140 reflect the light entering the lens barrel housing 110, the imaging sensor 120 receives the reflected light for imaging processing, and the wide-angle sensor 130 detects the position of the target based on the received light, realizing a dual-camera function with multiple reflections. This effectively extends the optical path length inside the lens barrel and also enables target tracking and imaging. The wide-angle sensor 130 can also be used for independent imaging to obtain images with a different perspective than the imaging sensor 120.

[0035] Optionally, the imaging sensor 120 may include one or more image sensors. These image sensors can be various types of CMOS (Complementary Metal-Oxide-Semiconductor) sensors, CCD (Charge-Coupled Device) devices, or other devices that convert light signals into electrical signals to achieve the corresponding imaging function. The wide-angle sensor 130 can be a low-resolution but high-sensitivity sensor with guiding capabilities, such as a high-sensitivity monochrome CMOS sensor. It has higher light-gathering efficiency, enabling it to capture fainter stars in shorter exposure times, thus improving guiding response speed and accuracy. In the field of astronomical photography, because the field of view of the imaging sensor 120 is relatively narrow, there may not be a sufficiently bright target suitable for guiding within that narrow field of view. Therefore, a wide-angle sensor 130 with a short focal length and wide field of view can be used for guiding, allowing for monitoring and tracking of the target's position when its location changes.

[0036] Optionally, Figure 1Only one feasible embodiment with n=2, i.e., two reflectors 140, is shown. The reflectors 140 can be configured as plane mirrors, roof prisms, Porro prisms, or other devices capable of transmitting light. The reflectors 140 can be fixed inside the mirror housing 110 by screws, nuts, or other fixing structures, so that the reflectors 140 can maintain a stable position and state during the movement of the mirror structure, thereby enabling the reflectors 140 to accurately and stably reflect and transmit light during movement.

[0037] exist Figure 1 In the illustrated embodiment, the volume occupied by the lens barrel structure is effectively reduced, and the lens barrel structure can be fixed as a whole on an external device. This solves the problems of high assembly difficulty, unstable center of gravity, and poor optical path extension caused by irregularly shaped lens barrels, improves the practicality of the lens barrel structure, and makes it suitable for a variety of different shooting scenarios, meeting the imaging needs of various shooting scenarios.

[0038] It should be noted that the lens barrel housing 110 has a straight cylindrical structure, such as a straight cylindrical or square cylindrical structure. The straight cylindrical lens barrel structure can be fixed as a whole on the external equipment, which further reduces the disadvantage of unstable center of gravity caused by the irregular shape of the lens barrel structure when it moves, and improves the stability and accuracy of the lens barrel structure when it moves.

[0039] Please see Figure 2 , Figure 2 This is a schematic diagram of the internal reflection path of the first type of lens barrel structure provided in this application embodiment. n reflectors 140 are disposed at the same end inside the lens barrel housing 110. The n reflectors 140 combine to form a first type of reflection path S1. Light enters the imaging sensor 120 based on the first type of reflection path S1. The first type of reflection path S1 includes a U-shaped reflection path. To effectively extend the optical path length within the lens barrel structure, multiple reflectors 140 can be disposed at the same end of the lens barrel housing 110 to form a U-shaped reflection path S1, allowing light to enter the imaging sensor 120 based on the first type of reflection path S1 for imaging.

[0040] Optionally, in order to achieve a U-shaped reflection path, two reflectors 140 can be placed inside the lens housing 110 at opposite ends corresponding to the position of the imaging sensor 120, and the two reflectors 140 are respectively angled based on the port of the lens housing 110 that is close to it, for example, at 45 degrees to the port plane of the lens housing 110 and facing each other, so as to realize the transmission of light.

[0041] Please see Figure 3 , Figure 3 This is a schematic diagram of the internal reflection path of the second type of lens barrel structure provided in this application embodiment. Figure 4This is a schematic diagram of the internal reflection path of the third lens barrel structure provided in the embodiments of this application. Figure 5 This is a schematic diagram of the internal reflection path of the fourth lens barrel structure provided in the embodiments of this application. Figure 6 This is a schematic diagram of the internal reflection path of the fifth lens barrel structure provided in this application embodiment. n reflectors 140 are disposed at both ends inside the lens barrel housing 110, and the n reflectors 140 combine to form a second type of reflection path S2. Light enters the imaging sensor 120 based on the second type of reflection path S2. The second type of reflection path S2 includes: a Z-shaped reflection path (such as...). Figure 3 As shown), multiple Z-shaped combined reflection paths (such as...) Figure 4 As shown, Figure 4 Only one feasible multi-Z-shaped combined reflection path is shown; other multi-Z-shaped combined reflection paths with more reflections will not be elaborated upon, as well as multi-U-shaped combined reflection paths (such as...). Figure 5 As shown, Figure 5 Only one feasible multi-U-shaped combined reflection path is shown; other multi-U-shaped combined reflection paths with more reflections will not be described in detail, or Z-shaped + U-shaped combined reflection paths (such as...). Figure 6 As shown, Figure 6 Only one feasible Z-shaped + U-shaped combined reflection path is shown; other Z-shaped + U-shaped combined reflection paths with more reflections or different combination methods will not be described in detail. In order to effectively extend the optical path length within the lens barrel structure, multiple reflectors 140 can be disposed at both ends of the lens barrel housing 110 to form a Z-shaped reflection path (distributed at both ends), a multiple Z-shaped combined reflection path (sequentially disposed at both ends), a multiple U-shaped combined reflection path (formed by combining multiple U-shaped reflection paths disposed at both ends), or a Z-shaped + U-shaped combined reflection path (formed by combining Z-shaped and U-shaped reflection paths disposed at both ends) as a second reflection path, so that light can enter the imaging sensor 120 based on the second type of reflection path S2, and be captured by the imaging sensor 120 for imaging.

[0042] Optionally, to achieve a Z-shaped reflection path, two reflectors 140 can be provided. These two reflectors 140 are respectively positioned at opposite ends of the lens housing 110 corresponding to the position of the imaging sensor 120 and at the same end of the imaging sensor 120. The two reflectors 140 form corresponding angles based on the adjacent ports of the lens housing 110, for example, at 20 degrees to the port plane of the lens housing 110 and with their mirror surfaces facing each other, to achieve light transmission. A larger number of reflectors 140 can be provided in a sequentially opposite distribution to achieve multiple Z-shaped combined reflection paths (such as...). Figure 4 As shown), multiple sets of adjacent reflectors 140 can also be sequentially arranged at both ends of the mirror tube structure to achieve a multi-U-shaped combined reflection path (such as...). Figure 5(As shown), or, the Z-shaped reflection path can be combined with the U-shaped reflection path to achieve a Z-shaped + U-shaped combined reflection path (as shown). Figure 6 (As shown).

[0043] It should be noted that the first type of reflection path S1 and the second type of reflection path S2 provided in the embodiments of this application can provide the imaging sensor 120 with a longer optical path, a longer focal length and a larger focal ratio, which can be used to achieve a higher magnification. For a lens of a certain aperture, considering that an excessively large focal ratio will lead to an excessively narrow and dark field of view, the position of the reflector 140 can be radically designed according to the actual situation to determine the appropriate optical path, focal length and focal ratio.

[0044] Optionally, since the first type of reflection path S1 and the second type of reflection path S2 determine the optical path length of the imaging sensor 120, and the overall length of the first type of reflection path S1 and the second type of reflection path S2 is determined based on the axial length and radial width of the lens barrel housing 110, a lens barrel housing 110 of appropriate size can be designed according to the actual situation, and multiple reflectors 140 can be placed in appropriate positions within the lens barrel housing 110. This ensures that the structure within the lens barrel housing 110 is compact and reliable while meeting the optical path requirements of the imaging sensor 120.

[0045] For example, in astrophotography, for shooting scenarios with moderate focus requirements, such as large deep-sky object photography that needs to show the entire celestial body while retaining sufficient detail resolution, or capturing the overall view of a constellation or a specific area of ​​the sky and highlighting small constellations and starscapes within it, a suitable shooting method can be adopted. Figure 2 or Figure 3 The lens barrel structure is used for shooting, and it is suitable for shooting scenarios that require high focus, such as shooting distant, small, or extremely detailed celestial objects, such as planetary photography and close-up photography. Figures 4-6 Various lens barrel structures that can provide longer focal lengths can be used for shooting, and the appropriate lens barrel structure with the appropriate optical path length can be selected according to the actual shooting needs.

[0046] Optionally, please refer to Figure 7 , Figure 7This is a schematic diagram of another lens barrel structure provided in an embodiment of this application. The lens barrel housing 110 has a light inlet 151 at one end. A first-type lens 152 corresponding to the shooting sensor 120 and a second-type lens 153 corresponding to the wide-angle sensor 130 are fixedly mounted on the light inlet 151. The optical path area of ​​the first-type lens 152 does not overlap with the area of ​​the reflector 140 located near the end. To allow light to enter the lens barrel, a light inlet 151 can be provided at one end of the lens barrel housing 110. The first-type lens 152 for the shooting sensor 120 and the second-type lens 153 for the wide-angle sensor 130 are fixedly mounted on the light inlet 151 to achieve independent operation of the dual sensors for dual-camera functionality. Furthermore, it should be noted that, considering that the reflector 140 provided inside the lens barrel housing 110 may be located at one end near the light inlet 151, in order to reduce the adverse obstruction of light caused by the reflector 140, the optical path area of ​​the first type of lens 152 does not overlap with the area of ​​the reflector 140 located near the end. The position of the reflector 140, the position of the first type of lens 152, and the size of the lens aperture can be adjusted according to actual needs.

[0047] It should be noted that the first type of lens 152 and the second type of lens 153 can be selected and set according to the actual needs of the shooting sensor 120 and the wide-angle sensor 130, respectively. For example, in the field of astrophotography, the first type of lens 152 can be a telescope with a long focal length and a large aperture, such as a catadioptric telescope, and the second type of lens 153 can be a telescope with a small aperture and a short focal length, etc., to serve as a guide mirror. For example, in the field of astrophotography, the wide-angle sensor 130 and the second type of lens 153 can continuously capture a "guide star" when the externally connected equatorial mount or other devices produce small errors in tracking the starry sky (caused by polar axis inaccuracy, gear error, atmospheric refraction, etc.). Once a slight movement of the star is detected, a command is immediately sent to the equatorial mount for reverse correction, ensuring that the target remains stationary on the pixel during exposures lasting several minutes or even several hours, thereby obtaining a higher quality image.

[0048] It should be noted that, since the aperture of the first type of lens 152 is relatively large, and the reflector 140 is positioned close to the light inlet 151, the position of the reflector 140 will restrict the position and aperture of the first type of lens 152. Therefore, a suitable position and aperture of the first type of lens 152 can be selected based on the position of the reflector 140, and the position of the reflector 140 can be adjusted based on the position and aperture of the first type of lens 152. In the projection area perpendicular to the end plane, the optical path area of ​​the first type of lens 152 does not overlap with the area of ​​the reflector 140 positioned near the end, so that light can be reflected and transmitted normally. For example, in Figure 2In the first type of reflection path S1 shown, since the two reflectors 140 are both set at opposite ends of the light inlet 151, the position of the light inlet 151 at the end is relatively large, and a first type of lens 152 with a larger aperture can be set.

[0049] It should be noted that, considering the different positions of the reflector 140 inside the lens barrel structure, in order to enable normal light transmission, and considering that the optical paths of the wide-angle sensor 130 and the shooting sensor 120 are independent, the shooting sensor 120 is provided with a longer shooting optical path by the reflector 140, while the wide-angle sensor 130 requires a shorter optical path length, the positions of the shooting sensor 120 and the wide-angle sensor 130 can be set according to the actual situation.

[0050] Optionally, in Figure 2 In the illustrated embodiment, since both reflectors 140 are located at opposite ends of the light inlet 151, there is limited free space at the opposite ends. Furthermore, to achieve a longer shooting optical path and a shorter wide-angle optical path, both the shooting sensor 120 and the wide-angle sensor 130 are located at the first end near the light inlet 151. Figure 3 In the illustrated embodiment, since the two reflectors 140 are respectively disposed at both ends, in order to achieve a longer imaging optical path and a shorter wide-angle optical path, the wide-angle sensor 130 can be disposed at the first end closer to the light entrance 151, and the imaging sensor 120 can be disposed at the second end farther from the light entrance 151. This allows the imaging sensor 120 and the wide-angle sensor 130 to be properly disposed inside the lens barrel structure and to achieve normal imaging function.

[0051] It should be noted that in some shooting scenarios where the requirements for the shooting optical path are low, the shooting sensor 120 can also be set in the middle position at both ends of the lens barrel structure.

[0052] Please continue reading. Figure 7 Considering the need for focal length adjustment during shooting, the lens barrel structure may also include: a focusing component 160, which is fixedly installed inside the lens barrel housing 110. The focusing component 160 is connected to the shooting sensor 120 and is used to adjust the position of the shooting sensor 120 in the optical path, thereby realizing the focal length adjustment function and meeting the shooting needs of various different types of shooting targets in various different scenarios.

[0053] For example, the focusing component 160 can be configured as a device with position adjustment function, such as a motor, pulley, slider, worm gear, worm, etc.

[0054] It should be noted that the focusing component 160 can be fixed close to the shooting sensor 120. Figure 7The diagram shows a structure in which both the shooting sensor 120 and the wide-angle sensor 130 are located at the first end near the light inlet 151. In this structure, the focusing element 160 can also be located near the first end to efficiently adjust the focus of the shooting sensor 120.

[0055] Please see Figure 8 , Figure 8 This is a schematic diagram of an imaging device provided in an embodiment of this application. The imaging device includes a driving structure 200 and a lens barrel structure 100 as described in any of the above embodiments. The driving structure 200 is connected to the lens barrel structure 100 and is used to drive the lens barrel structure 100 to move. Considering the movement requirements of tracking shooting, the imaging device may include a driving structure 200. The lens barrel structure 100 is connected to the driving structure 200 as a whole, and the driving structure 200 drives the lens barrel structure 100 to move. This effectively reduces the difficulty of assembling the lens barrel structure 100 and improves the stability of driving the lens barrel structure 100 to move. The lens barrel structure 100 can also provide a longer optical path length, obtain a larger focal ratio under the premise of a certain aperture, effectively optimize the shooting effect of the imaging device, and is suitable for a variety of different shooting scenarios, meeting the imaging needs of a variety of different shooting scenarios.

[0056] Optionally, the drive structure 200 may include various structures with transmission and drive functions, and the drive structure 200 may be equipped with various types of devices with transmission functions such as motors, transmission belts, lead screws, worm gears, and worms.

[0057] Optionally, considering that the size of the drive structure 200 will affect the lens barrel structure 100 when it is placed inside the lens barrel structure 100, and that the heat and vibration generated by the drive structure 200 during operation will also have an adverse effect on the lens barrel structure 100, the drive structure 200 can be connected to the outer wall of the lens barrel shell 110 of the lens barrel structure 100 by welding or fasteners such as screws and nuts to drive the lens barrel structure 100 to move. The drive structure 200 can be fixedly connected to the middle position of the lens barrel structure 100 to improve the stability of the center of gravity when driving the lens barrel structure 100. During use, when the cylindrical lens barrel structure 100 is raised or lowered, the area of ​​any folding plane is relatively controllable and less affected by wind.

[0058] Optionally, please refer to Figure 9 , Figure 9This is a schematic diagram of the specific structure of an imaging device provided in an embodiment of this application. In order to realize the automatic tracking and shooting function of the target, the drive structure 200 can be provided with a first drive structure 210 and a second drive structure 220 to control the movement of the lens barrel structure 100 in different directions. The first drive structure 210 is connected to the outer wall of the lens barrel shell 110 of the lens barrel structure 100, and the second drive structure 220 is connected to the first drive structure 210 to control the lens barrel structure 100 to move synchronously in two different axes, horizontal and vertical.

[0059] In this design, the first drive structure 210 has a first motion axis L1 parallel to the mounting surface M of the imaging device. The first drive structure 210 drives the lens barrel structure 100 to rotate based on the first motion axis L1, thereby changing the height angle. The second drive structure 220 has a second motion axis L2 perpendicular to the mounting surface M of the imaging device. The second drive structure 220 drives the lens barrel structure 100 to rotate based on the second motion axis L2, thereby changing the horizontal orientation. This design enables movement control along both the horizontal and vertical axes, effectively improving the efficiency and accuracy of the imaging device's automatic target tracking.

[0060] Please continue reading. Figure 9 For data transmission and processing, the imaging device may further include a controller 320 and an electrical connector 330. To house the electrical connector 330, a first through-hole 311 is provided in the first drive structure 210, and a second through-hole 312 is provided in the barrel wall of the lens barrel housing 110. When the first drive structure 210 is fixedly connected to the outer barrel wall of the lens barrel housing 110, the positions of the first through-hole 311 and the second through-hole 312 correspond, allowing the electrical connector 330 to pass through the first through-hole 311 and the second through-hole 312. The imaging sensor 120 and the wide-angle sensor 130, both located in the lens barrel structure 100, are connected to the controller 320 via the electrical connector 330. The controller 320 receives and processes the imaging data collected by the imaging sensor 120 and the wide-angle sensor 130. This design utilizes the internal space of the first drive structure 210 for wiring, effectively reducing the space occupied by the electrical connector 330, meeting the miniaturization requirements of the imaging device, and enabling the corresponding data transmission and processing functions.

[0061] It should be noted that, in order to keep the inside of the lens barrel structure 100 closed and reduce the adverse effects of stray light on shooting, the edge of the second through hole 312 can be sealed with an opaque elastic element, and the electrical connector 330 passing through the second through hole 312 can be set along the inner wall of the lens barrel housing 110 to reduce the adverse effects caused by light entering the inside of the lens barrel housing 110 from the second through hole 312.

[0062] For example, controller 320 can be configured as various types of integrated circuit chips with signal processing capabilities. Controller 320 can be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it can also be a digital signal processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. Electrical connector 330 can be a flexible wire or other device capable of providing an electrical connection.

[0063] It should be noted that the controller 320 can also be connected to the drive structure 200 and the focusing component in the lens barrel structure 100. The controller 320 can receive adjustment commands sent by external electronic devices, such as mobile phones and computers, or receive and analyze shooting requirements sent by electronic devices to determine the adjustment force and direction of the drive structure 200 and the focusing component, so as to control the operation of the drive structure 200 and the focusing component.

[0064] Optionally, both the drive structure 200 and the controller 320 can be housed within the imaging device housing. The housing is connected to the lens barrel structure 100 to form a complete imaging device. The housing can contain a battery to power the controller 320, drive structure 200, and sensors and focusing components within the lens barrel structure 100. Additionally, the housing can contain indicator lights and communication modules (such as NFC modules and WIFI modules) to enable status display, identity pairing, and communication connection functions.

[0065] Optionally, to secure the imaging device, it can also be equipped with a base. This base can be connected to the end of a motion shaft extending outside the device housing via a second drive structure 220, allowing independent movement of the device housing and the lens barrel structure 100 while the base remains stationary. The base can be connected to the end of the motion shaft via various connectors. For example, it can be connected to the end of the motion shaft via a standard threaded interface with a tripod / wedge / ball table, or it can use a quick-release structure to match a relatively customized support structure. For instance, the base can be set with four equal sides (similar to a rounded square / circle), with four first protruding latches at the four corners / sides of the base's bottom surface, each latch spaced apart. A second protruding latch is similarly provided on the connecting end face of the tripod / wedge / ball table. The second protruding latches fit against the base through the gaps and rotate to engage the first and second latches. This allows for quicker assembly and disassembly, improving the installation and disassembly efficiency when switching between a standard tripod, equatorial mount mode ball table, and disassembled / split-body configuration. Meanwhile, connections with multiple and large contact surfaces are beneficial to improving equipment stability; multi-point contact can also reduce the risk of connection instability after thread wear.

[0066] Optionally, the outer shell of the device housing can be configured with a corresponding arc shape around its perimeter, the arc shape narrowing towards the center and extending downwards, and the interface shape of the device housing having a sharp lower edge (crescent-shaped) so that water droplets on the outer shell will not enter the housing from the lower edge, and even if the imaging device is tilted at a certain angle during disassembly and assembly, water droplets will drip off after flowing to the lower edge and will not enter the gap between the base and the device housing.
