This structure effectively supports both ends of the camera assembly, thereby improving the stability of the camera device during use and reducing the possibility of image jitter. By providing a cable passage space on the connecting plate, a first cable passage channel on the first mounting plate, a second cable passage channel on the second mounting plate, and a cable passage hole on the cable shaft, some cables connected to the control circuit board can sequentially pass through the cable passage space, the first cable passage channel, and the cable passage hole, and connect to the camera assembly via electrical signals to control the camera assembly's operation. Other cables connected to the control circuit board can sequentially pass through the cable passage space and the second cable passage channel, and connect to the stator assembly via electrical signals to control the camera assembly's rotation. In this camera device, by providing the cable passage space, the first cable passage channel, the cable passage hole, and the second cable passage channel, the cable threading paths are dispersed. This eliminates the need for internal holes in the rotating shaft and reduces the number of cables required to pass through the cable passage holes.

[0035] With the development of science and technology, PTZ live streaming camera equipment has gradually become an indispensable device for people's leisure, entertainment, and daily office work. In actual production, researchers have found that most PTZ live streaming camera devices use a single-point support method to mount the camera component onto the bracket, that is, mounting the stator assembly onto the bracket, and then rotating the camera component onto the stator assembly. However, during use, camera devices mounted in this way are prone to axial or radial movement due to poor structural stability, causing image jitter. Furthermore, during cable routing, all cables need to be threaded through holes inside the shaft, which increases the difficulty of cable routing and assembly when there are many cables. Moreover, threading numerous cables through holes inside the shaft can easily lead to cable breakage due to wear when the camera component rotates, thus affecting signal transmission.

[0036] This utility model proposes a camera device, which aims to solve the technical problems of poor stability, difficulty in wiring, and easy damage of cables in camera devices used for live streaming on PTZ cameras.

[0037] Please see Figures 1 to 4In one embodiment of this utility model, the camera device includes a bracket 100, a mounting block 200, a wire guide spool 300, a stator assembly 400, a camera assembly 500, and a communication assembly. The bracket 100 is provided with a control circuit board. The mounting block 200 includes an integrally formed connecting plate 210, a first mounting plate 220, and a second mounting plate 230. The connecting plate 210 is disposed on the bracket 100 and has a wire guide space 211. The first mounting plate 220 and the second mounting plate 230 are spaced apart from the connecting plate 210. The first mounting plate 220 has a first wire guide channel 221 communicating with the wire guide space 211 and a first mounting hole 222 communicating with the first wire guide channel 221. The second mounting plate 230 has a second wire guide channel 231 communicating with the wire guide space 211 and a first mounting hole 222 communicating with the first wire guide channel 221. The second mounting hole 232 is connected to the second wire passage 231. The wire guide 300 is disposed in the first mounting hole 222 and has a wire guide hole 310 communicating with the first wire passage 221. The stator assembly 400 is disposed in the second mounting hole 232. One end of the camera assembly 500 is rotatably disposed in the stator assembly 400 and the other end of the camera assembly 500 is rotatably disposed in the wire guide 300. The communication assembly includes multiple cables 600, all of which are disposed on the control circuit board. Some cables 600 pass through the wire passage space 211, the first wire passage 221 and the wire guide hole 310 in sequence and are electrically connected to the camera assembly 500. Other cables 600 pass through the wire passage space 211 and the second wire passage 231 in sequence and are electrically connected to the stator assembly 400.

[0038] The technical solution of this utility model improves the stability of the camera device during use by mounting the camera assembly 500 on the U-shaped mounting block 200 to form a double-point support structure. Simultaneously, by optimizing the wiring path of the camera device, the difficulty of wiring is reduced, and the possibility of wear and breakage due to the large number of cables 600 is decreased. In this embodiment, the bracket 100 provides support, and the control circuit board mounted on it controls the rotation and operation of the camera assembly 500. The control circuit board transmits signals through the cable 600. The mounting block 200 is U-shaped. One end of the camera assembly 500 is rotatably mounted on the first mounting hole 222 of the first mounting plate 220 via the guide shaft 300, and the other end is rotatably mounted on the second mounting hole 232 of the second mounting plate 230 via the stator assembly 400, thus forming a double-point support structure. This structure effectively supports both ends of the camera assembly 500, thereby improving the stability of the camera device during use and effectively preventing image jitter. By providing a wire-passing space 211 on the connecting plate 210, a first wire-passing channel 221 on the first mounting plate 220, a second wire-passing channel 231 on the second mounting plate 230, and a wire-passing hole 310 on the wire-passing shaft 300, some cables 600 connected to the control circuit board can pass through the wire-passing space 211, the first wire-passing channel 221, and the wire-passing hole 310 in sequence, and be electrically connected to the camera assembly 500 to control the operation of the camera assembly 500; while other cables 600 connected to the control circuit board can pass through the wire-passing space 211 and the second wire-passing channel 231 in sequence, and be electrically connected to the stator assembly 400 to control the rotation of the camera assembly 500. In this camera device, the cable 600's threading path is dispersed by setting up a cable-passing space 211, a first cable-passing channel 221, a cable-passing hole 310, and a second cable-passing channel 231. This eliminates the need for internal perforations within the rotating shaft 510, optimizing the cable 600's threading path and reducing the difficulty of threading. Furthermore, using an independent cable-passing shaft 300 allows for larger diameter cable-passing holes 310, effectively preventing wear and breakage of the numerous cables 600 during cable threading. This camera device is applicable to technical fields such as pan-tilt-zoom camera equipment.

[0039] In one embodiment of this utility model, one end of the camera assembly 500 is provided with a rotating shaft 510 and a rotor 520. The stator assembly 400 includes a stator base 410 and a stator winding 420. The stator base 410 is disposed in the second mounting hole 232 and is rotatably connected to the rotating shaft 510 through a first bearing 511. The rotor 520 is arranged around the outside of the rotating shaft 510, and the stator winding 420 is arranged around the stator base 410 and disposed inside the rotor 520. In this embodiment, the stator base 410 is rotatably connected to the rotating shaft 510 through the first bearing 511, which can reduce the frictional force when the rotating shaft 510 rotates and ensure the stability of the rotating shaft 510 during rotation, thereby ensuring the stability of the camera assembly 500 during rotation. In a specific embodiment, there are two first bearings 511, which are spaced apart along the axial direction of the rotating shaft 510.

[0040] In one embodiment of this utility model, a locking member 512 is provided at the end of the rotating shaft 510 away from the camera assembly 500. The locking member 512 abuts against the end face of the stator base 410 opposite to the camera assembly 500. In this embodiment, by providing the locking member 512 at the end of the rotating shaft 510 away from the camera assembly 500, the position of the rotating shaft 510 can be restricted, preventing the rotating shaft 510 from separating from the stator base 410, thereby preventing the camera assembly 500 from separating from the stator base 410. In a specific embodiment, the locking member 512 includes a fastening nut and a sensing magnet. The fastening nut is threadedly connected to the end of the rotating shaft 510 away from the camera assembly 500, and the sensing magnet is installed on the fastening nut. A detection circuit board is provided on the stator base 410, and a Hall element is provided on the detection circuit board. The Hall element can sense the change in the magnetic field when the rotating shaft 510 drives the sensing magnet to rotate, thereby confirming the rotation angle of the camera assembly 500.

[0041] In one embodiment of this utility model, the stator assembly 400 further includes a fixing member 430, which passes through the stator base 410 and is connected to the second mounting plate 230. In this embodiment, the fixing member 430 is used to lock the stator base 410 to ensure that the stator base 410 is stably positioned when installed into the second mounting hole 232. In a specific embodiment, the fixing member 430 may be a bolt.

[0042] In one embodiment of this utility model, a first limiting block 540 is provided on the camera component 500 corresponding to the position of the spool 300, and a second limiting block 320 is provided on the spool 300. The first limiting block 540 can abut against both sides of the second limiting block 320. In this embodiment, the first limiting block 540 and the second limiting block 320 serve a limiting function; through the cooperation of the first limiting block 540 and the second limiting block 320, the rotation angle of the camera component 500 can be limited to prevent the user from rotating the camera component 500 excessively, which would cause the camera component 500 to fail to capture the desired image.

[0043] In one embodiment of this utility model, the other end of the camera assembly 500 is rotatably connected to the bobbin 300 via a second bearing 530, and lubricant is applied to the inner and outer surfaces of the first bearing 511, the inner surface of the second bearing 530, and the outer surface of the second bearing 530. In this embodiment, the rotatable connection of the other end of the camera assembly 500 to the bobbin 300 via the second bearing 530 reduces the frictional force when the camera assembly 500 rotates around the bobbin 300 and ensures the stability of the camera assembly 500 during rotation. By applying lubricant to the inner and outer surfaces of the first bearing 511, the inner and outer surfaces of the second bearing 530, and the camera assembly 500, respectively, the friction of the camera assembly 500 during rotation can be reduced, wear between the connecting parts can be reduced, and the service life of the camera device can be extended.

[0044] In one embodiment of this utility model, the thread guide 300 is provided with a stepped portion; one end of the second bearing 530 abuts against the side of the first mounting plate 220 facing the second mounting plate 230, and the other end abuts against the stepped portion. The camera device also includes a limiting plate 700 and a locking block 800. The limiting plate 700 is disposed on the side of the first mounting plate 220 away from the second mounting plate 230, and the locking block 800 passes through the limiting plate 700 and is connected to the thread guide 300. In this embodiment, by abutting the stepped portion of the thread guide 300 against the end of the second bearing 530 near the second mounting plate 230, and by connecting the locking block 800 through the limiting plate 700 to the thread guide 300, the thread guide 300 can be more securely and firmly installed in the first mounting hole 222, thereby ensuring that the installation of the thread guide 300 is reliable and secure. In one specific embodiment, the locking block 800 can be a bolt; during installation, the threaded end of the locking block 800 passes through the limiting plate 700 and is threadedly connected to the bobbin 300. Specifically, when the locking block 800 is tightened, it pulls the camera assembly 500 toward the first mounting plate 220, thereby balancing the visual gaps between the two ends of the camera assembly 500 and the two mounting plates, thus improving the aesthetics of the camera device.

[0045] In one embodiment of this utility model, the following are defined: A is the axial clearance between the first bearing 511 and the stator base 410 in the direction of the central axis of the rotating shaft 510; B is the axial clearance between the limiting plate 700 and the first mounting plate 220 in the direction of the central axis of the guide shaft 300; and C is the sum of the axial clearance of the first bearing 511, the axial clearance of the second bearing 530, and the deformation of the mounting block 200 in the direction of the central axis of the rotating shaft 510. Therefore, A > B, A + B > C. D is the radial clearance between the second bearing 530 and the guide shaft 300 in the radial direction of the guide shaft 300; E is the radial clearance between the second bearing 530 and the camera assembly 500 in the radial direction of the guide shaft 300; and F is the sum of the radial clearance of the first bearing 511, the radial clearance of the second bearing 530, and the deformation of the concentricity of the first mounting hole 222 and the second mounting hole 232. Therefore, E + D > F.

[0046] It should be noted that in this embodiment, the mounting block 200 is integrally injection molded from thermoplastic material, and it will undergo a certain degree of plastic deformation during cooling and solidification. This deformation will cause deviations in the axial length of the mounting block 200 and the camera assembly 500, as well as the concentricity of the first mounting hole 222 and the second mounting hole 232. In the case of a gapless design, the camera device is in a tight fit. However, when the axial length is small or large, the first bearing 511 and the second bearing 530 will be subjected to external pressure, causing misalignment of the inner and outer rings. If the deformation exceeds the clearance standard, the friction generated when the first bearing 511 and the second bearing 530 rotate will exceed the allowable driving force range for the drive motor to drive the camera assembly 500 to rotate. At this time, the camera assembly 500 will experience jamming or vibration. The camera device controls the relationship between the axial clearances A and B and the sum C of the axial clearances of the first bearing 511, the axial clearance of the second bearing 530, and the deformation of the mounting block 200 in the direction of the central axis of the rotating shaft 510; and the relationship between the radial clearances D and E and the sum F of the radial clearances of the first bearing 511, the radial clearance of the second bearing 530, and the deformation of the concentricity of the first mounting hole 222 and the second mounting hole 232. This allows it to absorb the axial and radial clearances of the first bearing 511 and the second bearing 530, as well as the deformation of the mounting block 200, ensuring smooth rotation of the first bearing 511 and the second bearing 530 when the rotor 520 assembly rotates, thereby preventing axial or radial vibration of the camera assembly 500 during rotation. Furthermore, by making the axial clearance A greater than the axial clearance B, when locking the locking block 800 on the wire-passing side, its fastening force can be used to clamp the limiting plate 700 and the wire-passing shaft 300, thereby pulling the camera assembly 500 towards the wire-passing side, so that the clearance of the camera assembly 500 on the motor side and the wire-passing side is balanced, thereby improving the aesthetics of the camera device.

[0047] In one embodiment of this utility model, a receiving groove 330 is provided at one end of the wire hole 310 near the first mounting plate 220. The receiving groove 330 is used to receive the cable 600, and the bottom surface of the receiving groove 330 is an arc-shaped surface. In this embodiment, by providing a receiving groove 330 with a smooth bottom surface at one end of the wire hole 310 near the first mounting plate 220 to receive the cable 600, the torsional force generated by the cable 600 due to its own torsion when the camera assembly 500 rotates can be reduced. At the same time, it can also prevent the limiting plate 700 from being pushed out due to the rebound of the cable 600, thus ensuring the aesthetic appearance of the camera device.

[0048] In one embodiment of this utility model, the mounting block 200 further includes a cover plate 240; the first end of the cover plate 240 covers the first mounting plate 220 and forms a first wire passage 221 with the first mounting plate 220; the second end of the cover plate 240 covers the second mounting plate 230 and forms a second wire passage 231 with the second mounting plate 230; the middle part of the cover plate 240 covers the connecting plate 210 and forms a wire passage space 211 with the connecting plate 210. In this embodiment, the mounting block 200 is an integrally formed structure, which can reduce the tolerances or gaps caused by the mutual cooperation between multiple components; the cover plate 240 is used to cover the cable 600 to improve the aesthetics of the camera device.

[0049] In another embodiment of this utility model, in conventional camera devices, due to the weight limitation of the camera assembly 500, the signal transmission of its lens module usually requires a long cable 600 to be transferred from the control circuit board of the bracket 100 to the camera assembly 500, resulting in a long transmission path. This camera device utilizes a dual-point support structure to support the camera assembly 500, which increases the weight of the camera assembly 500 that the mounting block 200 can support. Therefore, this camera device can integrate the part of the control circuit board that controls the operation of the camera assembly 500 into an adapter circuit board, directly mounting the adapter circuit board to the camera assembly 500, and transmitting signals to the lens module via the adapter circuit board. This reduces the number of cables 600 that need to be routed from the control circuit board to the camera assembly 500, and also shortens the signal transmission distance of the lens module to avoid signal loss. Specifically, the camera assembly 500 includes a housing, a lens module, and an adapter circuit board. The adapter circuit board is disposed in the housing and electrically connected to the control circuit board, and the lens module is disposed in the housing and electrically connected to the adapter circuit board.
