Description

Technical Field

[0001] This application belongs to the field of camera device design technology, and specifically relates to a camera device. Background Technology

[0002] Currently, camera devices are widely used in various locations. A typical camera device consists of a body module and a lens module. The lens module is usually rotatably mounted on the body module, allowing it to rotate relative to the body module and thus increasing the camera's shooting range. With technological advancements, users expect camera devices to have even greater shooting ranges. To further expand the shooting range and reduce blind spots, related technologies utilize multiple lenses within the lens module to enrich the camera's field of view, thereby reducing blind spots and further expanding the shooting range. In specific applications, users manually rotate the lens module to adjust the shooting angle. However, this structure results in a relatively heavy lens module, requiring users to exert significant force when rotating it, which can negatively impact operational convenience and user experience. Utility Model Content

[0003] This utility model discloses a camera device to alleviate the problem that the camera devices involved in related technologies have difficulty in conveniently driving the lens module to rotate, which easily affects the user experience.

[0004] To alleviate the above-mentioned technical problems, this utility model provides the following technical solution: In a first aspect, this application discloses a camera device, which includes a lens module, a first drive mechanism, and a body module; The lens module includes a housing, which is rotatably mounted on the body module about a first axis. The housing has an interconnected inner cavity and a clearance opening. A first drive mechanism is located in the inner cavity and passes through the clearance opening to drively connect with the body module. The first drive mechanism is used to drive the housing to rotate about the first axis relative to the body module, thereby causing the lens module to rotate about the first axis relative to the body module.

[0005] Secondly, this application discloses a camera device, which includes a lens module, a first driving mechanism, and a body module; The lens module includes a housing, which is rotatably disposed on the body module about a first axis. The housing has an inner cavity, and a first driving mechanism is disposed in the inner cavity and drivenly connected to the body module. The first driving mechanism is used to drive the housing to pitch and rotate about the first axis relative to the body module, thereby causing the lens module to pitch and rotate about the first axis relative to the body module. The first drive mechanism includes a first power source and a first transmission component connected together; The fuselage module includes a second transmission component that meshes with the gear of the first transmission component. The second transmission component is constructed as an upwardly protruding arc-shaped gear structure.

[0006] The technical solution adopted in this utility model can achieve the following technical effects: The camera device disclosed in this application improves the structure of camera devices related to the related technology by setting the lens module as a structure including a housing, allowing the lens module to be rotatably mounted on the body module around a first axis via the housing. By setting the housing as a structural component with interconnected inner cavities and clearance openings, and by setting the first drive mechanism in the inner cavity and connecting the first drive mechanism through the clearance opening to drive the body module, the first drive mechanism can drive the housing to rotate relative to the body module around the first axis, thereby enabling the lens module to rotate relative to the body module around the first axis. Since the lens module is driven to rotate relative to the body module around the first axis by the first drive mechanism, the user does not need to manually drive the lens module to rotate, thus making it more convenient to drive the lens module to rotate and improving the user experience.

[0012] Please refer to Figures 1 to 18 This application discloses a camera device, which includes a lens module 100, a first drive mechanism 210, and a body module 300.

[0013] The lens module 100 is the core component of the camera device that enables the shooting function, while the body module 300 is the basic component of the camera device, providing mounting positions for other components. The lens module 100 is located within the body module 300, meaning the body module 300 provides a mounting position for the lens module 100. The lens module 100 includes a housing 110, which is rotatably mounted on the body module 300 about a first axis. This allows the housing 110 to rotate relative to the body module 300 about the first axis, enabling the lens module 100 to have a relatively wide field of view.

[0014] The first drive mechanism 210 is the core component in the camera device that drives the lens module 100 to rotate. The lens module 100 also provides mounting positions for other components of the camera device. The housing 110 has an interconnected inner cavity 111 and a clearance opening 112. The first drive mechanism 210 is located in the inner cavity 111, wherein a portion of the structure of the first drive mechanism 210 can be located within the inner cavity 111, and the first drive mechanism 210 passes through the clearance opening 112 and is driven to connect with the body module 300. The first drive mechanism 210 is used to drive the housing 110 to rotate relative to the body module 300 about a first axis, thereby causing the lens module 100 to rotate relative to the body module 300 about the first axis. Thus, the first drive mechanism 210 drives the lens module 100 to rotate relative to the body module 300 about the first axis.

[0015] Optionally, one of the lens module 100 and the body module 300 may include a first connecting shaft 120, and the other of the lens module 100 and the body module 300 may be provided with a connecting groove 331. The first connecting shaft 120 is rotatably disposed in the connecting groove 331, the central axis of the first connecting shaft 120 may coincide with the first axis, and the groove opening of the connecting groove 331 may be parallel to the direction of the first axis, thereby facilitating the rotational connection between the lens module 100 and the body module 300 around the first axis. In one embodiment, the groove opening of the connecting groove 331 may be vertically upward, thereby providing support for the first connecting shaft 120 and preventing the lens module 100 from falling off.

[0016] When the lens module 100 includes a first connecting shaft 120, the first connecting shaft 120 can be connected to the outside of the housing 110 by means of threaded connection, snap-fit, integral molding, etc. Correspondingly, the body module 300 can be provided with a connecting groove 331. When the body module 300 includes a connecting cover 330 as described later, the connecting groove 331 can be located inside the connecting cover 330. At the same time, in order to improve the stability of the connection between the lens module 100 and the body module 300, there can be two first connecting shafts 120 and two connecting grooves 331. The two first connecting shafts 120 can be located on opposite sides of the housing 110 in the first axial direction, and the two connecting grooves 331 can be located on opposite sides of the connecting cover 330 in the first axial direction. In addition, in order to facilitate the connection between the first connecting shaft 120 and the housing 110, the first connecting shaft 120 can be a bolt, screw, etc. The specific type of the first connecting shaft 120 is not limited in this application embodiment. In this case, the bolt or screw that acts as the first connecting shaft 120 rotates with the connecting groove 331.

[0017] The camera device disclosed in this application improves the structure of camera devices related to the relevant technology by setting the lens module 100 to include a housing 110, allowing the lens module 100 to be rotatably mounted on the body module 300 via the housing 110 about a first axis. The housing 110 is configured as a structural member having an interconnected inner cavity 111 and a clearance opening 112. Furthermore, a first drive mechanism 210 is located in the inner cavity 111 and connected to the body module 300 via the clearance opening 112. This allows the first drive mechanism 210 to drive the housing 110 to rotate relative to the body module 300 about the first axis, thereby enabling the lens module 100 to rotate relative to the body module 300 about the first axis. Since the lens module 100 is driven to rotate relative to the body module 300 about the first axis by the first drive mechanism 210, the user does not need to manually drive the lens module 100, making it more convenient to drive and improving the user experience.

[0018] Furthermore, this structure, by placing the first drive mechanism 210 in the inner cavity 111, allows the first drive mechanism 210 to be placed in the lens module 100, thereby reducing the space occupied by the first drive mechanism 210 in the body module 300. This helps to avoid situations where the body module 300 cannot accommodate the first drive mechanism 210, making it difficult to drive the lens module 100 to rotate relative to the body module 300 around the first axis, which could easily affect the user experience.

[0019] In a further technical solution, the first drive mechanism 210 may include a first power source 211 and a first transmission component 212, and the body module 300 may include a second transmission component 310. The first power source 211 may be disposed in the inner cavity 111, the first transmission component 212 may be disposed in the inner cavity 111, and the second transmission component 310 may be opposite to the clearance opening 112, so that the first transmission component 212 passes through the clearance opening 112 and is connected to the second transmission component 310 for transmission. Specifically, the first power source 211 may be a motor, and the specific type of the first power source 211 is not limited in the embodiments of this application.

[0020] The first power source 211 can be connected to the first transmission component 212. The first power source 211 may include a first output shaft 217, which can be fixedly connected to the first transmission component 212 by means of threaded connection, snap-fit, etc., so that the first power source 211 can drive the first transmission component 212 to rotate. The first transmission component 212 can be connected to the second transmission component 310 through the clearance opening 112. The first power source 211 is used to drive the first transmission component 212 to rotate, so that the first transmission component 212 can drive the housing 110 to rotate around the first axis relative to the fuselage module 300 through the second transmission component 310. The first power source 211 can be connected to the fuselage module 300 in sequence through the first transmission component 212 and the second transmission component 310, so that the drive connection between the first drive mechanism 210 and the fuselage module 300 can be realized relatively easily.

[0021] Furthermore, when the fuselage module 300 includes the adapter plate 340 described below, the second transmission member 310 may be located on the side of the adapter plate 340 facing the housing 110. The second transmission member 310 may be connected to the adapter plate 340 by means of threaded connection, snap-fit, etc. This application embodiment does not limit this.

[0022] In one embodiment, the first transmission component 212 can be a first gear, and the second transmission component 310 can be a first arc-shaped rack. The first arc-shaped rack can extend around a first axis, so that the transmission connection between the first gear and the first arc-shaped rack can be realized through the mutual meshing between the first gear and the first arc-shaped rack, thereby achieving a more precise and efficient transmission.

[0023] Of course, in other embodiments, the first transmission member 212 can be a first sprocket, and the second transmission member 310 can be a first arc-shaped chain. The first arc-shaped chain can extend around the first axis, so that the transmission connection between the first sprocket and the first arc-shaped chain can be realized through the mutual meshing between the first sprocket and the first arc-shaped chain.

[0024] To facilitate the installation of the first power source 211 and the first transmission component 212, in one embodiment, the first drive mechanism 210 may further include a housing 214. The first power source 211 can be installed on the housing 214 by means of threaded connection, snap-fit, etc. The housing 214 can be at least partially disposed in the inner cavity 111. The housing 214 can be connected to the housing 110 by means of threaded connection, snap-fit, etc., so that the first power source 211 and the first transmission component 212 can be connected to the housing through the housing 214, thereby facilitating the connection between the first drive mechanism 210 and the housing 110.

[0025] In optional technical solutions, the fuselage module 300 may further include a limiting mating member 320, and the first drive mechanism 210 may further include a limiting trigger member 213. The limiting trigger member 213 may be disposed in the inner cavity 111 and may be opposite to the clearance opening 112, so that the limiting mating member 320 can trigger the limiting trigger member 213 through the clearance opening 112. Specifically, the limiting trigger member 213 may be a micro switch, and the specific type of the limiting trigger member 213 is not limited in the embodiments of this application.

[0026] In the specific operation, when the lens module 100 rotates to its limit angle relative to the body module 300 around the first axis, the limiting mating member 320 can extend into the inner cavity 111 through the clearance opening 112 to trigger the limiting trigger member 213. The lens module 100 can determine its first rotation stroke around the first axis relative to the body module 300 based on the limit angle, thereby minimizing the possibility of excessive rotation of the lens module 100 around the first axis relative to the body module 300, which could make it difficult for the first transmission member 212 to connect with the second transmission member 310, thus affecting the drive connection between the first drive mechanism 210 and the lens module 100. It should be noted that the first rotation stroke can correspond to the first rotation range of the lens module 100 around the first axis relative to the body module 300, and the embodiments of the present invention do not limit the specific angular value of the first rotation range.

[0027] Specifically, the direction of the first axis can be parallel to the horizontal direction. The lens module 100 can be rotated around the first axis relative to the body module 300 to adjust the tilt angle or elevation angle of the lens module 100. When the lens module 100 is rotated around the first axis relative to the body module 300 to the limit angle, the lens module 100 can be in a tilting state or a downward state. That is, the limit angle can be the maximum elevation angle or the maximum tilt angle of the lens module 100.

[0028] Furthermore, the limiting engagement member 320 can be provided at the end of the first arc-shaped rack, so that when the first gear moves to the end of the first arc-shaped rack, the limiting trigger member 213 can drive the limiting engagement member 320 to trigger. Since the first gear is located at the end of the first arc-shaped rack at this time, the first gear can roll fully along the first arc-shaped rack, so that the first arc-shaped rack can fully mesh with the first gear.

[0029] In the embodiments disclosed in this application, the camera device may further include a mounting base 400, which is also a basic component of the camera device and is used to provide mounting positions for other components of the camera device. The body module 300 may be disposed on the mounting base 400, that is, the mounting base 400 can provide a mounting position for the body module 300. The body module 300 may further include a connecting cover 330 and an adapter plate 340. The adapter plate 340 is rotatably disposed on the mounting base 400 about a second axis, and the connecting cover 330 may be disposed on the side of the adapter plate 340 facing away from the mounting base 400, so that the body module 300 is rotatably disposed on the mounting base 400 about the second axis, thereby allowing the body module 300 to rotate relative to the mounting base 400 about the second axis. Specifically, the connecting cover 330 may be connected to the adapter plate 340 by means of threaded connection, snap-fit, etc., and this embodiment of the application does not limit this.

[0030] The housing 110 is rotatably mounted on the connecting cover 330 about a first axis. The first drive mechanism 210 can pass through the clearance opening 112 and be driven to connect to the adapter plate 340. The first drive mechanism 210 is used to drive the housing 110 to rotate about the first axis relative to the connecting cover 330, so that the housing 110 rotates about the first axis relative to the body module 300, thereby enabling the lens module 100 to rotate about the first axis relative to the body module 300. The direction of the first axis may intersect with the direction of the second axis.

[0031] In this structure, since the body module 300 can rotate relative to the mounting base 400 around the second axis, and the housing 110 is rotatably disposed on the connecting cover 330 around the first axis, the body module 300 can drive the housing 110 to rotate relative to the mounting base 400 around the second axis. This allows the body module 300 to drive the lens module 100 to rotate relative to the mounting base 400 around the second axis. At the same time, the lens module 100 can rotate relative to the body module 300 around the first axis, and the direction of the first axis intersects the direction of the second axis. This allows the lens module 100 to achieve two-dimensional rotation, thereby enabling the lens module 100 to rotate more flexibly and to have a wider field of view, which is beneficial for enriching the application scenarios of the camera device.

[0032] Preferably, the direction of the first axis can be perpendicular to the direction of the second axis. This structure can prevent the lens module 100 from changing its rotation angle around the first axis when the body module 300 drives the lens module 100 to rotate around the second axis relative to the mounting base 400, and can also prevent the lens module 100 from changing its rotation angle around the second axis when the body module 300 drives the lens module 100 to rotate around the second axis relative to the mounting base 400. This avoids interference between the rotation of the lens module 100 around the first axis and the rotation of the lens module 100 around the second axis, thereby improving the accuracy of the rotation of the lens module 100. Specifically, the direction of the first axis can be parallel to the horizontal direction, and the direction of the second axis can be parallel to the vertical direction.

[0033] Optionally, the adapter plate 340 may include a second connecting shaft 343, and the mounting base 400 may be provided with a connecting hole 420. The second connecting shaft 343 is rotatably disposed in the connecting hole 420. The central axis of the second connecting shaft 343 and the central axis of the connecting hole 420 may both coincide with the second axis, so that the adapter plate 340 is rotatably disposed in the mounting base 400 about the second axis.

[0034] Specifically, the second connecting shaft 343 can be positioned and engaged with the connecting hole 420 along the second axis direction in a direction away from the mounting base 400. For example, a connector can be provided on the end face of the connecting hole 420 away from the adapter plate 340, and the connector can be fixedly connected to the second connecting shaft 343. In actual use, the user can fix the mounting base 400 to the ceiling by means of threaded connection, adhesive bonding, etc. In this case, the second axis direction can be parallel to the vertical direction. The second connecting shaft 343 can be positioned and engaged with the connecting hole 420 along the second axis direction in a direction away from the mounting base 400 to minimize the separation of the adapter plate 340 from the mounting base 400, which would cause the body module 300 to separate from the mounting base 400.

[0035] In one embodiment, the adapter plate 340 may include a limiting step 341, which may extend around the second axis and be distributed on the edge of the adapter plate 340. The mounting base 400 may include a limiting protrusion 410, which may be located on the side of the limiting step 341 facing the housing 110. The limiting protrusion 410 may contact the limiting step 341 in a direction away from the housing 110. The limiting protrusion 410 and the limiting step 341 may be distributed along the second axis, so that the limiting step 341 overlaps the limiting protrusion 410. This structure can minimize the possibility of the adapter plate 340 separating from the mounting base 400, which would cause the body module 300 to separate from the mounting base 400, and thus cause the body module 300 and the lens module 100 connected to the body module 300 to separate from the mounting base 400. This is beneficial to improving the stability of the camera device.

[0036] In practical use, when the user fixes the mounting base 400 to the ceiling, the second axis direction can be parallel to the vertical direction. In this case, the overlapping cooperation between the limiting protrusion 410 and the limiting step 341 further strengthens the connection between the body module 300 and the lens module 100 and the mounting base 400 in the second axis direction. This makes it less likely for the body module 300 and the lens module 100 to separate from the mounting base 400, thus preventing them from falling and injuring people or animals below the camera device, thereby improving the safety of the camera device. Furthermore, when the adapter plate 340 includes the second connecting shaft 343, even if the second connecting shaft 343 breaks, the cooperation between the limiting protrusion 410 and the limiting step 341 can still minimize the separation of the body module 300 and the lens module 100 from the mounting base 400.

[0037] Furthermore, the limiting step 341 may be provided with a plurality of spaced-apart clearance grooves 342, and there may be a plurality of limiting protrusions 410. The plurality of limiting protrusions 410 may be spaced-apart around the second axis. The plurality of limiting protrusions 410 may pass through the plurality of clearance grooves 342 one by one and be positioned on the side of the limiting step 341 facing the housing 110 by the relative rotation of the adapter plate 340 and the mounting base 400 around the second axis. That is, the plurality of clearance grooves 342 may be spaced-apart around the second axis, thereby making it easier to install the plurality of limiting protrusions 410 onto the side of the limiting step 341 facing the housing 110.

[0038] In other words, after the multiple limiting protrusions 410 pass through the multiple clearance slots 342 in a one-to-one correspondence, the fuselage module 300 can have an initial angle. At this time, the fuselage module 300 can be rotated around the second axis relative to the mounting base 400 by a certain angle, so that the adapter plate 340 rotates around the second axis relative to the mounting base 400 by a certain angle, and the multiple limiting protrusions 410 are respectively disposed on the side of the limiting step 341 facing the housing 110. This allows at least some of the multiple limiting protrusions 410 to be misaligned with the multiple clearance slots 342, so that the limiting step 341 can overlap on at least some of the multiple limiting protrusions 410.

[0039] In the specific operation, when the body module 300 rotates relative to the mounting base 400 around the second axis, at least some of the multiple limiting protrusions 410 can be misaligned with the multiple clearance grooves 342, so that at least some of the multiple limiting protrusions 410 can contact the limiting step 341 in the direction away from the housing 110. This structure, by setting multiple limiting protrusions 410, can more stably contact the limiting step 341 in the direction away from the housing 110, which helps to further reduce the risk of the body module 300 and lens module 100 separating from the mounting base 400 in the direction of the second axis, thereby helping to further improve the stability of the imaging device. In addition, in order to alleviate stress concentration, the multiple limiting protrusions 410 can be spaced apart and evenly distributed around the second axis, and the multiple clearance grooves 342 can be spaced apart and evenly distributed around the second axis.

[0040] It should be noted that the fuselage module 300 may have a second rotational stroke, which may correspond to a second rotational range of the fuselage module 300 relative to the mounting base 400 around the second axis. This embodiment of the invention does not limit the specific angular value of the second rotational range. When the fuselage module 300 rotates relative to the mounting base 400 around the second axis, the second rotational range can be designed so that it does not include the initial angle, thereby ensuring that the fuselage module 300 never rotates to the initial angle. This ensures that at least some of the multiple limiting protrusions 410 can be misaligned with the multiple clearance grooves 342, thereby ensuring that the limiting step 341 can engage with at least some of the multiple limiting protrusions 410.

[0041] In one feasible technical solution, the camera device may further include a second drive mechanism 220. The second drive mechanism 220 may be disposed on the mounting base 400 and may be drivenly connected to the adapter plate 340. The second drive mechanism 220 is used to drive the adapter plate 340 to rotate relative to the mounting base 400 around the second axis, so that the body module 300 rotates relative to the mounting base 400 around the second axis, thereby facilitating the rotation of the body module 300 around the second axis relative to the mounting base 400, so that the body module 300 can drive the lens module 100 to rotate relative to the mounting base 400 around the second axis.

[0042] For example, the fuselage module 300 may also include a fourth transmission component 350, and the second drive mechanism 220 may include a second power source 221 and a third transmission component 222 connected together. The second power source 221 is fixedly connected to the mounting base 400 by means of threaded connection or snap-fit, and the second power source 221 may include a second output shaft 223. The second output shaft 223 may be fixedly connected to the third transmission component 222 by means of threaded connection or snap-fit, so that the second power source 221 can drive the third transmission component 222 to rotate. The third transmission component 222 can be connected to the fourth transmission component 350. The second power source 221 is used to drive the third transmission component 222 to rotate, so that the third transmission component 222 can drive the fuselage module 300 to rotate around the second axis relative to the mounting base 400 through the fourth transmission component 350. That is, the second power source 221 can be connected to the fuselage module 300 in sequence through the third transmission component 222 and the fourth transmission component 350, so that the drive connection between the second drive mechanism 220 and the fuselage module 300 can be realized more conveniently.

[0043] Specifically, the third transmission member 222 and the fourth transmission member 350 can be connected by gear meshing. In this case, the third transmission member 222 and the fourth transmission member 350 can be the second gear and the third gear, respectively. Alternatively, the third transmission member 222 and the fourth transmission member 350 can be connected by pulley transmission. In this case, the third transmission member 222 and the fourth transmission member 350 can be the driving pulley and the driven pulley, respectively, and they can be connected by a transmission belt. Furthermore, the second power source 221 can be an electric motor; however, this application embodiment does not limit the specific type of the second power source 221.

[0044] In addition, when the body module 300 includes the adapter plate 340, the fourth transmission component 350 can be connected to the side of the adapter plate 340 away from the housing 110 by means of threaded connection, snap-fit, etc.

[0045] In one embodiment, the second power source 221 may further include a second power source body 224, a second seal 225, and a second sealing plate 226. The second power source body 224 may be fixedly connected to the second output shaft 223 by means of threaded connection, snap-fit, etc., so that the second power source body 224 can drive the second output shaft 223 to rotate. The second power source body 224 may be disposed in the mounting base 400, and the second output shaft 223 may extend out of the mounting base 400 and be connected to the third transmission component 222.

[0046] The second seal 225 and the second sealing plate 226 can be sleeved on the second output shaft 223, and the second sealing plate 226 can press the second seal 225 to the mounting base 400 so that the second seal 225 can seal with the second output shaft 223 and the mounting base 400 respectively, thereby minimizing the intrusion of moisture and other substances from outside the mounting base 400 into the mounting base 400 from between the second output shaft 223 and the mounting base 400 and affecting the normal operation of the second power source body 224.

[0047] Specifically, the second seal 225 can be a sealing ring, and the second sealing pressure plate 226 can be connected to the mounting base 400 by threaded connection or snap-fit, thereby pressing the second seal 225 to the mounting base 400. To facilitate the installation of the second seal 225, the mounting base 400 can be provided with a second mounting groove 430, in which the second seal 225 can be positioned, and the second sealing pressure plate 226 can seal the opening of the second mounting groove 430 to press the second seal 225 to the bottom wall of the second mounting groove 430.

[0048] In the embodiments disclosed in this application, the housing 110 may have at least one viewing window 113, and the lens module 100 may further include at least one lens. The lens may be disposed in the inner cavity 111 and correspond one-to-one with the viewing window 113 to facilitate the shooting function of the lens module 100. Furthermore, the housing 110 may also include an isolation portion 114, which may be disposed in the inner cavity 111 and divide the inner cavity 111 into a first sub-cavity 101 and a second sub-cavity 102. The second sub-cavity 102 may communicate with a clearance opening 112. The lens may be disposed in the first sub-cavity 101, and the first driving mechanism 210 may be disposed in the second sub-cavity 102. This structure can reduce the risk of dust and moisture entering the first sub-cavity 101 through the clearance opening 112 and easily affecting the internal environment of the first sub-cavity 101, thereby minimizing the impact on the normal operation of the lens. Additionally, when the first driving mechanism 210 includes a housing 214, the housing 214 may be connected to the isolation portion 114 by means of threaded connection, snap-fit, or other methods.

[0049] This application also discloses a camera device, which includes a lens module 100, a first drive mechanism 210, and a body module 300. The lens module 100 includes a housing 110, and the lens module 100 is rotatably disposed on the body module 300 about a first axis. The housing 110 has an inner cavity 111, and the first drive mechanism 210 is disposed in the inner cavity 111 and is drivenly connected to the body module 300. The first drive mechanism 210 is used to drive the housing 110 to pitch and rotate relative to the body module 300 about the first axis, thereby causing the lens module 100 to pitch and rotate relative to the body module 300 about the first axis. That is, the direction of the first axis can be parallel to the horizontal direction.

[0050] The first drive mechanism 210 includes a first power source 211 and a first transmission component 212 connected together. The first power source 211 can be connected to the first transmission component 212 by means of threaded connection, snap-fit, etc., so that the first power source 211 can drive the first transmission component 212 to rotate. The body module 300 includes a second transmission component 310 that meshes with the first transmission component 212 by a gear, so that the first power source 211 can drive the second transmission component 310 to rotate around a first axis by the gear meshing between the first transmission component 212 and the second transmission component 310. This allows the first drive mechanism 210 to drive the housing 110 to pitch and rotate around the first axis relative to the body module 300, and the first drive mechanism 210 to drive the lens module 100 to rotate around the first axis relative to the body module 300. This makes it easier to drive the lens module 100 to rotate, which is beneficial to improving the user experience. In addition, the housing 110 may also have a clearance opening 112 communicating with the inner cavity 111, through which the first transmission member 212 can pass and mesh with the second transmission member 310.

[0051] The second transmission member 310 is constructed as an upwardly protruding arc-shaped gear structure. The first transmission member 212 can be located below the second transmission member 310, and the first transmission member 212 can be located inside the second transmission member 310, that is, the first transmission member 212 can be located on the side of the second transmission member 310 facing the first axis. This structure allows the second transmission member 310 to avoid the lens module 100 while meshing with the first transmission member 212 gear, thereby improving the compactness of the camera device structure.

[0052] Furthermore, this structure, by placing the first drive mechanism 210 in the inner cavity 111, allows the first drive mechanism 210 to be placed in the lens module 100, thereby reducing the space occupied by the first drive mechanism 210 in the body module 300. This helps to avoid situations where the body module 300 cannot accommodate the first drive mechanism 210, making it difficult to drive the lens module 100 to rotate relative to the body module 300 around the first axis, which could easily affect the user experience.

[0053] Optionally, the body module 300 may further include an adapter plate 340, and the second transmission member 310 may be disposed within the space enclosed by the inner side of the adapter plate 340 and the outer side of the housing 110, thereby making full use of the space enclosed by the inner side of the adapter plate 340 and the outer side of the housing 110, which is beneficial to improving the compactness of the camera device structure. Specifically, the inner side of the adapter plate 340 may be the side of the adapter plate 340 facing the housing 110, and the space enclosed by the inner side of the adapter plate 340 and the outer side of the housing 110 may communicate with the inner cavity 111 through the clearance opening 112, so that the first transmission member 212 passes through the clearance opening 112 and meshes with the second transmission member 310.

[0054] Furthermore, the first drive mechanism 210 can be modularized to form an assembly with the fuselage module 300. Specifically, the first drive mechanism 210 can be a modular structure, that is, the components of the first drive mechanism 210 can be pre-assembled before the first drive mechanism 210 is installed into the inner cavity 111, so that the first drive mechanism 210 can be directly installed into the inner cavity 111, making the first drive mechanism 210 modularized to form an assembly with the fuselage module 300, thereby helping to reduce the complexity of installation.

[0055] In one embodiment, the first drive mechanism 210 may further include a limit trigger 213, which may be connected to the first transmission member 212. The limit trigger 213 may be connected to the first transmission member 212 through the housing 214, which enables the first transmission member 212 to drive the limit trigger 213 to pitch and rotate about the first axis relative to the body module 300.

[0056] When the first transmission member 212 drives the limit trigger member 213 to move from one end of the arc gear structure to the other end of the arc gear, the limit trigger member 213 can be subjected to physical pressure to generate an electrical signal, which is used to indicate the critical point of the camera device's pitch rotation to a preset angle. Specifically, the limit trigger member 213 can be disposed in the inner cavity 111 and can be opposite to the clearance opening 112. The limit trigger member 213 can be pressed by the limit fitting member 320 extending from the clearance opening 112 into the inner cavity 111 and subjected to physical pressure, thereby generating an electrical signal.

[0057] This structure allows the lens module 100 to determine its first rotational stroke relative to the body module 300 around the first axis based on the critical point, so as to avoid excessive pitch rotation of the lens module 100 relative to the body module 300 around the first axis, which could cause the first transmission component 212 to separate from the arc gear structure, thus making it difficult for the first transmission component 212 to mesh with the arc gear structure and affecting the drive connection between the first drive mechanism 210 and the lens module 100.

[0058] It should be noted that when the first transmission component 212 drives the limit trigger component 213 to move to one end of the arc gear structure or the other end of the arc gear, the limit trigger component 213 can be subjected to physical pressure to generate an electrical signal. In other words, the critical point can correspond to the maximum elevation angle or the maximum depression angle of the lens module 100.

[0059] In optional technical solutions, the first drive mechanism 210 may further include a housing 214, a first seal 215, and a first sealing pressure plate 216. When the first drive mechanism 210 includes a limit trigger 213, the limit trigger 213 can be fixed outside the housing 214 by means of threaded connection, snap-fit, or other methods.

[0060] The first power source 211 may include a first output shaft 217 and a first power source body 218 connected together. The first power source body 218 may be disposed inside the housing 214, and the first output shaft 217 may extend outside the housing 214 and be connected to the first transmission member 212. The first seal 215 and the first sealing plate 216 may both be disposed on the side of the first transmission member 212 facing the housing 214, and the first seal 215 and the first sealing plate 216 may both be sleeved on the first output shaft 217. The first sealing plate 216 can press the first seal 215 tightly against the housing 214, so that the first seal 215 can seal with the first output shaft 217 and the housing 214 respectively, thereby minimizing the intrusion of moisture from outside the housing 214 into the housing 214 from between the first output shaft 217 and the housing 214 and affecting the normal operation of the first power source body 218.

[0061] Specifically, the first sealing element 215 can be a sealing ring, and the first sealing pressure plate 216 can be connected to the outer shell 214 by means of threaded connection or snap-fit, thereby pressing the first sealing element 215 to the outer shell 214. In order to facilitate the installation of the first sealing element 215, a first mounting groove 219 can be provided on the outer shell 214. The first sealing element 215 can be positioned in the first mounting groove 219, and the first sealing pressure plate 216 can block the opening of the first mounting groove 219 to press the first sealing element 215 to the bottom wall of the first mounting groove 219.
