[0028] With the continuous development of technology, gimbals have been increasingly widely used in photography, videography, and security. Gimbals drive the shooting device to rotate through brushless motors. In related technologies, the main body of the brushless motor (stator and rotor) is usually installed inside the gimbal or directly exposed between the gimbal and the camera, resulting in a large size of the gimbal or a complex overall appearance and structure of the gimbal camera, which is not conducive to the application and installation of the gimbal camera.
[0029] This utility model proposes a shooting device, aiming to solve the technical problem of how to make the shooting device more compact.
[0030] In the embodiments of this utility model, such as Figures 1 to 3As shown, the shooting device includes:
[0031] Shooting device 10, the shooting device 10 includes a housing 11 and a lens module 12 installed in the housing 11, and a first mounting groove 111 is recessed on the outer surface of the housing 11;
[0032] Mounting gimbal 20 is used to fix it to an external structure. The mounting gimbal 20 has a first through hole 21 that communicates with its inner cavity. The first through hole 21 is opposite to the slot of the first mounting groove 111.
[0033] The first brushless motor 30 includes a first fixed base 31, a first stator 32, and a first rotor 33. The first fixed base 31 includes a first fixed plate 311 and a first connecting shaft 312 protruding from the first fixed plate 311. The first fixed plate 311 is installed in the inner cavity of the mounting gimbal 20. The first connecting shaft 312 extends out of the mounting gimbal 20 from the first through hole 21 and extends into the first mounting groove 111. The first stator 32 and the first rotor 33 are received in the first mounting groove 111. The first stator 32 is fixed to the first connecting shaft 312. The first rotor 33 is arranged around the first stator 32 and rotatably connected to the first connecting shaft 312. The first rotor 33 is fixedly connected to the first mounting groove 111 to drive the shooting device 10 to rotate.
[0034] In this embodiment, the shooting device 10 can form and record an image using optical imaging principles. The lens module 12 is installed inside the housing 11, which conceals and protects the lens module 12. A gimbal 20 is used to fix the shooting device 10 to an external structure, such as a drone or a head-mounted device. The shooting device 10 is mounted on the gimbal 20 via a first brushless motor 30, allowing the shooting device 10 to rotate relative to the gimbal 20. The user can then adjust the shooting angle of the shooting device 10 by controlling the first brushless motor 30.
[0035] The first stator 32 of the first brushless motor 30 is fixed to the first connecting shaft 312, and the first rotor 33 is rotatably connected to the first connecting shaft 312 via bearings. That is, the first rotor 33 can rotate relative to the first connecting shaft 312 and the first stator 32. Since the first rotor 33 is fixedly installed in the first mounting groove 111, its rotation can drive the imaging device 10 to rotate synchronously. The first mounting groove 111 can conceal and protect the first rotor 33 and the first stator 32.
[0036] The first stator 32 and the first rotor 33 are the larger parts in the first brushless motor 30. By housing the first stator 32 and the first rotor 33 in the first mounting slot 111 of the shooting device 10, the first stator 32 and the first rotor 33 do not need to occupy the internal space of the mounting gimbal 20, thereby reducing the overall volume of the mounting gimbal 20 and making it more compact. It also prevents the first brushless motor 30 from being directly exposed, making the overall appearance and structure of the shooting device simpler and more compact. Compared with installing the first stator 32 and the first rotor 33 in the mounting gimbal 20, installing the first stator 32 and the first rotor 33 in the first mounting slot 111 results in a smaller increase in the volume of the shooting device 10. That is, the volume of the shooting device 10 will not increase significantly, thus keeping the overall appearance of the shooting device simple and compact, which is convenient for the application and installation of the shooting device.
[0037] Specifically, such as Figures 1 to 3 As shown, the mounting gimbal 20 includes a fixed gimbal 22 and a movable gimbal 23. The fixed gimbal 22 is used to fix the gimbal to an external structure. The movable gimbal 23 is L-shaped and includes a connecting part 231 and a mounting part 232 connected at an angle. The connecting part 231 is rotatably mounted on the fixed gimbal 22. The shooting device 10 is located on the side of the connecting part 231 away from the fixed gimbal 22. The first fixing plate 311 is installed in the inner cavity of the mounting part 232. The first through hole 21 is opened in the mounting part 232. The rotation axis of the connecting part 231 is perpendicular to the rotation axis of the shooting device 10.
[0038] The shooting device 10 is located in the area semi-enclosed by the connecting part 231 and the mounting part 232. The movable gimbal 23 can rotate relative to the fixed gimbal 22, and the shooting device 10 can rotate relative to the movable gimbal 23. The rotation axis of the shooting device 10 is perpendicular to the rotation axis of the movable gimbal 23, so that the shooting device 10 can be controlled by dual-axis rotation, so that the shooting device 10 can have more selectable shooting angles.
[0039] In practical applications, such as Figures 2 to 3As shown, the connecting part 231 has a second mounting groove 233 recessed on the side facing the fixed gimbal 22. The fixed gimbal 22 has a second through hole 221 communicating with its inner cavity. The second through hole 221 is opposite to the groove opening of the second mounting groove 233. The shooting device also includes a second brushless motor 40. The second brushless motor 40 includes a second fixed base 41, a second stator 42, and a second rotor 43. The second fixed base 41 includes a second fixed plate 411 and a second connecting shaft 412 protruding from the second fixed plate 411. Plate 411 is installed in the inner cavity of the fixed gimbal 22. The second connecting shaft 412 extends out of the fixed gimbal 22 from the second through hole 221 and extends into the second mounting groove 233. The second stator 42 and the second rotor 43 are received in the second mounting groove 233. The second stator 42 is fixed to the second connecting shaft 412. The second rotor 43 is arranged around the second stator 42 and rotatably connected to the second connecting shaft 412. The second rotor 43 is fixedly connected to the second mounting groove 233 to drive the movable gimbal 23 to rotate.
[0040] The second stator 42 of the second brushless motor 40 is fixed to the second connecting shaft 412, and the second rotor 43 is rotatably connected to the second connecting shaft 412 via bearings. That is, the second rotor 43 can rotate relative to the second connecting shaft 412 and the second stator 42. Since the second rotor 43 is fixedly installed in the second mounting slot 233, its rotation can drive the imaging device 10 to rotate synchronously. The second mounting slot 233 can conceal and protect the second rotor 43 and the second stator 42.
[0041] The second stator 42 and the second rotor 43 are the larger parts in the second brushless motor 40. By housing the second stator 42 and the second rotor 43 in the second mounting slot 233 of the connecting part 231, the second stator 42 and the second rotor 43 do not need to occupy the internal space of the fixed gimbal 22, thereby reducing the overall volume of the mounting gimbal 20 and making the mounting gimbal 20 more compact. It also prevents the second brushless motor 40 from being directly exposed, so that the overall appearance and structure of the shooting equipment is simpler and more compact.
[0042] For example, such as Figure 2 and Figure 3As shown, the shooting device also includes a main control board 50 installed in the fixed gimbal 22. The second connecting shaft 412 is provided with a second wiring channel 413. One end of the second wiring channel 413 passes through the end of the second connecting shaft 412, and the other end passes through the second fixed plate 411. The bottom of the second mounting groove 233 is provided with a second wire hole 234, which connects the inner cavity of the connecting part 231 to the second wiring channel 413. The first brushless motor 30 also includes a first electrical connector 34. One end of the first electrical connector 34 is installed on the first fixed plate 311 and electrically connected to the first stator 32. The other end extends from the mounting part 232 along the connecting part 231, the second wire hole 234, and the second wiring channel 413 into the fixed gimbal 22 and is electrically connected to the main control board 50.
[0043] The main control board 50 supplies electrical energy to the first stator 32 and transmits control signals through the first electrical connector 34. A Hall sensor is installed on the first electrical connector 34 to detect the position of the first rotor 33. By obtaining the position of the first rotor 33, the main control board 50 can adjust the current supplied to the first stator 32 according to the position of the first rotor 33 to ensure the continuous rotation of the first rotor 33.
[0044] The first electrical connector 34 can be a flexible printed circuit board (FPC). The wiring path of the first electrical connector 34 is: mounting part 232 - connecting part 231 - second wiring hole 234 - second wiring channel 413 - fixed gimbal 22, and finally electrically connected to the main control board 50 inside the fixed gimbal 22. The second wiring hole 234 and the second wiring channel 413 pass through the rotation axis of the second rotor 43, so that the first electrical connector 34 will not affect the rotation process of the second rotor 43 after passing through the second wiring channel 413. In this way, the normal rotation of the second rotor 43 can be guaranteed, and the first electrical connector 34 can be effectively electrically connected to the main control board 50.
[0045] Specifically, such as Figure 2 and Figure 3 As shown, the first connecting shaft 312 is provided with a first wiring channel 313. One end of the first wiring channel 313 passes through the end of the first connecting shaft 312, and the other end passes through the first fixing plate 311. The bottom of the first mounting groove 111 is provided with a first wire-passing hole 112. The first wire-passing hole 112 connects the inner cavity of the outer shell 11 with the first wiring channel 313. The electrical connection wire of the lens module 12 extends from the inner shell 11 along the first wire-passing hole 112, the first wiring channel 313, the mounting part 232, the connecting part 231, the second wire-passing hole 234, and the second wiring channel 413 to the fixed gimbal 22 and is electrically connected to the main control board 50.
[0046] The main control board 50 is also used to provide power to the lens module 12 and transmit control signals. The wiring path of the electrical connection cable of the lens module 12 is: housing 11 - mounting part 232 - connecting part 231 - second wiring hole 234 - second wiring channel 413 - fixed gimbal 22, and finally electrically connected to the main control board 50 inside the fixed gimbal 22. The first wiring hole 112 and the first wiring channel 313 pass through the rotation axis of the first rotor 33, so that the electrical connection cable of the lens module 12 will not affect the rotation process of the first rotor 33 after passing through the first wiring channel 313. In this way, the normal rotation of the first rotor 33 and the second rotor 43 can be guaranteed, and the electrical connection cable of the lens module 12 can be effectively electrically connected to the main control board 50.
[0047] In practical applications, such as Figure 2 and Figure 3 As shown, the second brushless motor 40 also includes a second electrical connector 44. One end of the second electrical connector 44 is mounted on the second fixing plate 411 and electrically connected to the second stator 42, and the other end is electrically connected to the main control board 50.
[0048] The second electrical connector 44 is installed inside the fixed gimbal 22. The main control board 50 provides power to the second stator 42 and transmits control signals through the second electrical connector 44. A Hall sensor is installed on the second electrical connector 44 to detect the position of the second rotor 43. By obtaining the position of the second rotor 43, the main control board 50 can adjust the current supplied to the second stator 42 according to the position of the second rotor 43 to ensure the continuous rotation of the second rotor 43.
[0049] For example, such as Figure 2 and Figure 3 As shown, the mounting part 232 is provided with a first boss 235, and the first fixing plate 311 is fixedly connected to the first boss 235. The first boss 235 can improve the structural strength of the part connected to the first fixing seat 31 in the movable gimbal 23, thereby improving the installation stability of the first fixing seat 31 in the movable gimbal 23.
[0050] Specifically, such as Figure 2 and Figure 3 As shown, the fixed gimbal 22 is provided with a second protrusion 222, and the second fixing plate 411 is fixedly connected to the second protrusion 222. The second protrusion 222 can improve the structural strength of the part connected to the second fixing base 41 in the fixed gimbal 22, thereby improving the installation stability of the second fixing base 41 in the fixed gimbal 22.
[0051] In practical applications, the lens module 12 includes an imaging unit 121 and a lens 122. The lens 122 is detachably mounted on the imaging unit 121. The housing 11 has a camera hole. One end of the lens 122 away from the imaging unit 121 is located at the camera hole. The shooting device 10 also includes a protective cover 13. The protective cover 13 is detachably mounted on the camera hole. The protective cover 13 has a light-transmitting area corresponding to the lens 122.
[0052] By opening the protective cover 13, the lens 122 can be exposed to the camera hole, and the lens 122 can be removed from the imaging unit 121 to replace it with a lens 122 of different specifications. This allows users to replace the lens 122 according to their own needs, thereby improving the performance of the shooting device 10.
[0053] This utility model also proposes a surgical field imaging device, which includes a head-mounted support and an imaging device. The specific structure of the imaging device is as described in the above embodiments. Since this surgical field imaging device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The head-mounted support is for wearing on the human head, and the mounting gimbal 20 of the imaging device is fixedly mounted on the front side wall of the head-mounted support.
[0054] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model.
