[0002] With the continuous development of science and technology, pan-tilt mechanisms are increasingly widely used in fields such as photography, imaging, and security. The pan-tilt mechanism uses a brushless motor to drive the rotation of the imaging device. In the related art, the imaging device used in combination with the pan-tilt mechanism is usually a small imaging device, which is lighter in weight and simpler in structure, making it easier to control and drive by the pan-tilt mechanism. In some application scenarios, the imaging device needs to capture high-resolution video images to express details, but the lens module of such a small imaging device is sealed in a housing and the lens cannot be replaced, so that users cannot replace lenses with different focal lengths, apertures, and light-gathering capabilities according to their own needs, which affects the use effect of the imaging device. Summary of the Invention

[0003] The main purpose of this application is to propose a photographing device that solves the technical problem of how to improve the use effect of a small photographing device.

[0004] In order to achieve the above object, the present application proposes an imaging device, which includes: a housing, the housing being provided with an attachment chamber and a shooting hole, the shooting hole being in communication with the attachment chamber; a lens module, the lens module being mounted in the mounting chamber, the lens module including a lens and an imaging unit, one end of the lens being positioned in the shooting hole and capturing an optical image through the shooting hole, and the other end of the lens being detachably connected to the imaging unit, making the lens replaceable; a protective cover, the protective cover detachably covering the photographing hole, the protective cover having a light-transmitting area corresponding to the lens;

[0005] In the technical solution of the photographic device of this application, the protective cover can be removed from the photographing hole to expose one end of the lens, and then the user can grasp or clamp the exposed end of the lens to remove it from the imaging unit and take it out of the mounting chamber through the photographing hole. After removing and removing the lens, the user can attach another lens to the imaging unit through the photographing hole and finally cover the photographing hole with the protective cover to achieve lens replacement. In this way, lens replacement is achieved by removing the lens from the imaging unit and removing the protective cover from the housing, so that the user can easily replace lenses with different focal lengths, apertures, and light-gathering capabilities according to their own needs, improving the use efficiency of the photographic device.

[0010] The present application proposes a photographing device 10 that solves the technical problem of how to improve the use effect of a small photographing device.

[0011] In an embodiment of the present application, as shown in Figures 1 to 5, the photographing device 10 includes: a housing 11, the housing 11 having a mounting chamber 113 and a photographing hole 114, the photographing hole 114 communicating with the mounting chamber 113; a lens module 12, the lens module 12 mounted on the mounting chamber 113, the lens module 12 including a lens 122 and an imaging unit 121, one end of the lens 122 positioned at the photographing hole 114 to capture an optical image through the photographing hole 114, the other end of the lens 122 detachably connected to the imaging unit 121 to enable replacement of the lens 122; a protective cover 13, the protective cover 13 detachably covering the photographing hole 114, the protective cover 13 having a light-transmitting area corresponding to the lens 122.

[0012] In this embodiment, the housing 11 forms the overall appearance structure of the photographing device 10, and the lens module 12 uses the optical imaging principle to form an image and record the image, where the lens 122 is used to capture the optical image through the photographing hole 114, and the imaging unit 121 is used to record the optical image.

[0013] The protective cover 13 provides dust protection and protection for the lens 122, and the light-transmitting area of ​​the protective cover 13 is a solid transparent area through which light can pass, and specifically, the light-transmitting area may be a piece of light-transmitting glass.

[0014] The protective cover 13 can be removed from the shooting hole 114, exposing one end of the lens 122 from the shooting hole 114. The user then grasps or clamps the exposed end of the lens 122 to remove it from the imaging unit 121, and then removes it from the mounting chamber 113 through the shooting hole 114. After removing and removing the lens 122, the user attaches another lens 122 to the imaging unit 121 through the shooting hole 114, and finally places the protective cover 13 over the shooting hole 114 to replace the lens 122. In this way, the lens 122 can be replaced by removing the lens 122 from the imaging unit 121 and removing the protective cover 13 from the housing 11. The user can easily replace lenses 122 with different focal lengths, apertures, and light-gathering capabilities according to their needs, thereby improving the usability of the photographing device 10.

[0015] The connection method between the lens 122 and the imaging unit 121 may be a fitting connection or a plug-in connection, and is not limited here, as long as the lens 122 and the imaging unit 121 are detachably connected.

[0016] 4, a connection hole 123 is formed in the imaging unit 121, and one end of the lens 122 is detachably fitted into the connection hole 123. By fitting the lens 122 into the connection hole 123, the fitting area between the lens 122 and the imaging unit 121 is increased, and the connection stability between the lens 122 and the imaging unit 121 can be improved.

[0017] For example, the fitting depth of the lens 122 and the connecting hole 123 is adjustable, allowing for focus adjustment of the lens 122. A focus-adjustable gap is formed between one end of the lens 122 located at the shooting hole 114 and the protective cover 13, and by changing the fitting depth of the lens 122 and the connecting hole 123, the gap between the lens 122 and the protective cover 13 can be adjusted, thereby adjusting the focal length of the lens 122. A user can remove the protective cover 13, manually adjust the focus of the lens 122, and then replace the protective cover 13 after completing the focus adjustment, thereby realizing the focus adjustment function of the photographing device 10 and further improving the usability of the photographing device 10.

[0018] The method for adjusting the fitting depth of the lens 122 and the connecting hole 123 may be to directly apply an acting force to the lens 122 in the depth direction of the connecting hole 123, or other methods may be used.

[0019] Specifically, a male thread is provided on the peripheral wall of the fitting portion of the lens 122 and the connection hole 123, and a female thread is provided on the hole wall of the connection hole 123. The lens 122 and the connection hole 123 are screwed together, so that the fitting depth of the lens 122 and the connection hole 123 can be adjusted by simply rotating the lens 122, thereby simplifying the focus adjustment process of the lens 122. Furthermore, the screw connection method simplifies the attachment and detachment method of the lens 122 and the connection hole 123, thereby improving the convenience of focus adjustment and attachment and detachment of the lens 122.

[0020] For example, as shown in Figures 3 and 5, the lens 122 protrudes from the shooting hole 114, the protective cover 13 includes a cover plate 131 and a side plate 132, the side plate 132 is connected to the periphery of the cover plate 131, the light-transmitting area is provided on the cover plate 131, the cover plate 131 faces the lens 122, and the side plate 132 surrounds the portion of the lens 122 protruding from the shooting hole 114.

[0021] After the protective cover 13 is removed from the shooting hole 114, the lens 122 protrudes from the shooting hole 114, allowing the user to easily grasp the lens 122 from outside the shooting hole 114 to adjust focus or remove the lens, improving user convenience. The thickness of the side plate 132 is greater than the length of the portion of the lens 122 protruding from the shooting hole 114, thereby ensuring a sufficient gap between the cover plate 131 and the lens 122 and allowing the shape of the protective cover 13 to fit the protruding portion of the lens 122, thereby ensuring the protective effect of the protective cover 13 on the lens 122.

[0022] Specifically, as shown in FIG. 5, the diameter of the shooting hole 114 gradually decreases from one end away from the mounting chamber 113 to the other end closer to the mounting chamber 113, thereby giving the shooting hole 114 a trumpet-like shape that widens outward. This provides a certain operating space for the user between the hole wall of the shooting hole 114 and the surrounding wall of the lens 122, further improving the convenience of focusing and removing the lens 122.

[0023] 2 to 5, the photographing device 10 further includes an attachment ring 14, which is disposed within the photographing hole 114 and surrounds the lens 122, and one end of the side plate 132 remote from the cover plate 131 is detachably connected to the attachment ring 14. Since the photographing hole 114 portion of the housing 11 is also subjected to force during the process of attaching and detaching the protective cover 13, the attachment ring 14 improves the structural strength of the photographing hole 114 portion of the housing 11, preventing the photographing hole 114 portion of the housing 11 from being easily damaged by repeated force due to repeated attachment and detachment of the protective cover 13, and improving the overall structural stability of the photographing device 10.

[0024] The connection method between the side plate 132 and the mounting ring 14 may be a fitting connection or a screw connection, and is not limited here, as long as the side plate 132 and the mounting ring 14 are detachably connected.

[0025] 3, an engaging claw 133 is provided at one end of the side plate 132 remote from the cover plate 131, and an engaging hole 141 that fits the engaging claw 133 is provided in the mounting ring 14, and the engaging claw 133 is detachably fitted into the engaging hole 141. In this way, the method for attaching and detaching the side plate 132 and the mounting ring 14 is simplified, and the process for attaching and detaching the protective cover 13 can be simplified.

[0026] In actual application, as shown in FIG. 3 , the side plate 132 is arranged in a square shape, and there are four engaging claws 133, which protrude from the four corners of the side plate 132, respectively. The mounting ring 14 includes an outer frame 142 and a ring body 143, and the outer frame 142 is connected to the hole wall of the shooting hole 114 at one end away from the mounting chamber 113. One end of the ring body 143 is connected to the outer frame 142 and the other end extends toward the inside of the mounting chamber 113. The outer frame 142 is arranged in a square shape, and the engaging holes 141 are opened in the outer frame 142. The number and positions of the engaging holes 141 correspond to the engaging claws 133, and each engaging claw 133 is detachably fitted into each engaging hole 141. By setting the number of engaging claws 133 and engaging holes 141 to four, the number of fitting and coupling positions between the protective cover 13 and the mounting ring 14 can be increased, improving the connection stability between the protective cover 13 and the mounting chamber 113. By providing four engaging claws 133 at the four corners of the rectangular side plate 132, the structural strength of the positions where the four engaging claws 133 are located can be increased, making it less likely for the side plate 132 to deform and improving the structural stability of the protective cover 13.

[0027] 6, the present application further provides a photographing device, which includes a pan-tilt mounting mechanism 20 and a photographing device 10, the specific structure of which can be referred to in the above embodiments, and the photographing device adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. Here, the pan-tilt mounting mechanism 20 is used to be fixedly mounted on an external structure, and the photographing device 10 is rotatably mounted on the pan-tilt mounting mechanism 20.

[0028] As shown in FIGS. 7 to 9, the present application proposes an imaging device that solves the technical problem of how to reduce the size of an imaging device.

[0029] In an embodiment of the present application, as shown in FIGS. 7 to 9, the photographing device includes: The photographing device 10 includes a housing 11 and a lens module 12 mounted in the housing 11, and a first mounting groove 111 is recessed on the outer surface of the housing 11; a mounting pan-tilt mechanism (20) for being fixedly mounted on an external structure, the mounting pan-tilt mechanism (20) having a first through-hole (21) communicating with its inner chamber, the first through-hole (21) facing the groove opening of the first mounting groove (111); a first brushless motor (30) including a first fixing base (31), a first stator (32) and a first rotor (33); the first fixing base (31) including a first fixing plate (311) and a first connecting shaft (312) protruding from the first fixing plate (311); the first fixing plate (311) being mounted in the inner chamber of the mounting pan-tilt mechanism (20); the first connecting shaft (312) protruding from the mounting pan-tilt mechanism (20) through the first through-hole (21) and extending into the first mounting groove (111); the first stator (32) and the first rotor (33) being accommodated in the first mounting groove (111); the first stator (32) being fixed to the first connecting shaft (312); the first rotor (33) surrounding the first stator (32) and rotatably connected to the first connecting shaft (312); the first rotor (33) being fixedly connected to the first mounting groove (111) to drive the photographic device (10) to rotate;

[0030] In this embodiment, the camera 10 uses optical imaging principles to form and record images, where the lens module 12 is mounted within a housing 11, which serves to shield and protect the lens module 12. The pan-tilt mounting mechanism 20 is used to secure the camera 10 to an external structure, such as a drone or a head-mounted support. The camera 10 is mounted to the pan-tilt mounting mechanism 20 via a first brushless motor 30, allowing the camera 10 to rotate relative to the pan-tilt mounting mechanism 20, and a user can adjust the shooting angle of the camera 10 by controlling the first brushless motor 30.

[0031] 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 a bearing, i.e., the first rotor 33 is rotatable relative to the first connecting shaft 312 and the first stator 32. Since the first rotor 33 is fixedly mounted in the first mounting groove 111, when the first rotor 33 rotates, the imaging device 10 rotates synchronously. The first mounting groove 111 serves to isolate and protect the first rotor 33 and the first stator 32.

[0032] The first stator 32 and the first rotor 33 account for a large volume proportion of the first brushless motor 30. By accommodating the first stator 32 and the first rotor 33 in the first mounting groove 111 of the photographing device 10, the first stator 32 and the first rotor 33 do not need to occupy the internal space of the mounting pan-tilt mechanism 20. This reduces the overall volume of the mounting pan-tilt mechanism 20, thereby realizing a more compact mounting pan-tilt mechanism 20. This also prevents the first brushless motor 30 from being directly exposed, making the overall external structure of the photographing device simpler and more compact. Compared to installing the first stator 32 and the first rotor 33 in the mounting pan-tilt mechanism 20, the increase in volume of the photographing device 10 due to installing the first stator 32 and the first rotor 33 in the first mounting groove 111 is relatively small. In other words, the volume of the photographing device 10 does not increase significantly. This allows the overall external appearance of the photographing device to be kept simple and compact, and makes it easier to install the photographing device in an application.

[0033] Specifically, as shown in Figures 7 to 9, the mounting pan-tilt mechanism 20 includes a fixed pan-tilt mechanism 22 and a movable pan-tilt mechanism 23, the fixed pan-tilt mechanism 22 is used for fixedly mounting on an external structure, the movable pan-tilt mechanism 23 is L-shaped, and the movable pan-tilt mechanism 23 includes a connection part 231 and a mounting part 232 connected at an angle to each other, the connection part 231 is rotatably mounted on the fixed pan-tilt mechanism 22, the photographing device 10 is located on the side of the connection part 231 away from the fixed pan-tilt mechanism 22, the first fixing plate 311 is mounted on the inner chamber of the mounting part 232, the first through-hole 21 is opened in the mounting part 232, and the rotation axis of the connection part 231 and the rotation axis of the photographing device 10 are perpendicular to each other.

[0034] The photographing device 10 is located within the area surrounded by the connection part 231 and the mounting part 232, the movable pan-tilt mechanism 23 is rotatable relative to the fixed pan-tilt mechanism 22, the photographing device 10 is rotatable relative to the movable pan-tilt mechanism 23, and the rotation axis of the photographing device 10 and the rotation axis of the movable pan-tilt mechanism 23 are perpendicular to each other, so that two-axis rotation control can be performed on the photographing device 10, and the photographing device 10 can have more selectable shooting angles.

[0035] In actual application, as shown in FIGS. 7 to 9, a second mounting groove 233 is recessed on the surface of the connecting part 231 facing the fixed pan-tilt mechanism 22, a second through-hole 221 communicating with the inner chamber of the fixed pan-tilt mechanism 22 is formed in the fixed pan-tilt mechanism 22, and the second through-hole 221 faces the groove opening of the second mounting groove 233. The photographing device further includes a second brushless motor 40, which includes a second fixing base 41, a second stator 42, and a second rotor 43. The second fixing base 41 includes a second fixing plate 411 and a second connecting shaft 412 protruding from the second fixing plate 411. The second fixed plate 411 is attached to the inner chamber of the fixed pan-tilt mechanism 22, the second connecting shaft 412 protrudes from the fixed pan-tilt mechanism 22 through the second through hole 221 and extends into the second mounting groove 233, the second stator 42 and the second rotor 43 are accommodated 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 is rotatably connected to the second connecting shaft 412, and the second rotor 43 is fixedly connected to the second mounting groove 233, so as to rotate the movable pan-tilt mechanism 23.

[0036] 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 a bearing, i.e., the second rotor 43 is rotatable relative to the second connecting shaft 412 and the second stator 42. Because the second rotor 43 is fixedly mounted in the second mounting groove 233, the second rotor 43 can rotate synchronously with the imaging device 10 when it rotates. The second mounting groove 233 can serve to isolate and protect the second rotor 43 and the second stator 42.

[0037] The second stator 42 and the second rotor 43 account for a large volume proportion of the second brushless motor 40, and by accommodating the second stator 42 and the second rotor 43 in the second mounting groove 233 of the connection part 231, the second stator 42 and the second rotor 43 do not need to occupy the internal space of the fixed pan-tilt mechanism 22, thereby reducing the overall volume of the mounted pan-tilt mechanism 20 and realizing a more compact mounted pan-tilt mechanism 20. This also prevents direct exposure of the second brushless motor 40, making the overall external structure of the photographic device simpler and more compact.

[0038] 7 to 9, the photographing device further includes a main control board 50 mounted in the fixed pan-tilt mechanism 22, the second connecting shaft 412 is provided with a second wiring passage 413, one end of the second wiring passage 413 passes through the end of the second connecting shaft 412, and the other end passes through the second fixing plate 411, the second mounting groove 233 has a second wiring through hole 234 at the bottom, and the second wiring through hole 234 is connected to the inner chamber of the connecting part 231. The first brushless motor 30 further includes a first electrical connection member 34, one end of which is attached to the first fixed plate 311 and electrically connected to the first stator 32, and the other end of which extends from the mounting portion 232, along the connection portion 231, the second wiring through hole 234 and the second wiring passage 413, into the fixed pan-tilt mechanism 22, and is electrically connected to the main control board 50.

[0039] The main control board 50 supplies power to the first stator 32 via the first electrical connection member 34 and transmits control signals, and a Hall sensor is attached to the first electrical connection member 34 and is used to detect the position of the first rotor 33. By obtaining the position of the first rotor 33, the main control board 50 adjusts the transport current to the first stator 32 based on the position of the first rotor 33, ensuring continuous rotation of the first rotor 33.

[0040] The first electrical connection member 34 may be a flexible circuit board (FPC), and the wiring path of the first electrical connection member 34 is from the mounting portion 232 to the connecting portion 231, the second wiring through-hole 234, the second wiring passage 413, and the fixed pan-tilt mechanism 22, and is finally electrically connected to the main control board 50 in the fixed pan-tilt mechanism 22. The second wiring through-hole 234 and the second wiring passage 413 pass through the rotation axis of the second rotor 43, so that the first electrical connection member 34 does not affect the rotation process of the second rotor 43 after passing through the second wiring passage 413, thereby not only ensuring the normal rotation of the second rotor 43 but also ensuring that the first electrical connection member 34 is effectively electrically connected to the main control board 50.

[0041] Specifically, as shown in Figures 7 to 9, a first wiring passage 313 is provided on the first connecting shaft 312, one end of the first wiring passage 313 penetrates the end of the first connecting shaft 312 and the other end penetrates the first fixing plate 311, a first wiring through hole 112 is opened at the bottom of the first mounting groove 111, the first wiring through hole 112 connects the inner chamber of the housing 11 with the first wiring passage 313, and the electrical connection wire of the lens module 12 extends from inside the housing 11 sequentially along the first wiring through hole 112, the first wiring passage 313, the mounting portion 232, the connection portion 231, the second wiring through hole 234 and the second wiring passage 413 to the fixed pan-tilt mechanism 22 and is electrically connected to the main control board 50.

[0042] The main control board 50 is also used to supply power and transmit control signals to the lens module 12. The electrical connecting line of the lens module 12 is routed from the housing 11 to the mounting portion 232, the connection portion 231, the second wiring through-hole 234, the second wiring passage 413, and the fixed pan-tilt mechanism 22, and is finally electrically connected to the main control board 50 in the fixed pan-tilt mechanism 22. The first wiring through-hole 112 and the first wiring passage 313 pass through the rotation axis of the first rotor 33, so that the electrical connecting line of the lens module 12 passes through the first wiring passage 313 without affecting the rotation process of the first rotor 33. This not only ensures the normal rotation of the first rotor 33 and the second rotor 43, but also ensures that the electrical connecting line of the lens module 12 is effectively electrically connected to the main control board 50.

[0043] In actual applications, as shown in Figures 7 to 9, the second brushless motor 40 further includes a second electrical connection member 44, one end of which is attached to the second fixing plate 411 and electrically connected to the second stator 42, and the other end of which is electrically connected to the main control board 50.

[0044] The second electrical connection member 44 is mounted within the fixed pan-tilt mechanism 22, and the main control board 50 supplies power to the second stator 42 and transmits control signals through the second electrical connection member 44. A Hall sensor is mounted on the second electrical connection member 44 and is used 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 transport current to the second stator 42 based on the position of the second rotor 43, ensuring continuous rotation of the second rotor 43.

[0050] As shown in Figures 10 to 13, the present application aims to propose a head-mounted support device that is highly portable and comfortable, and to solve the technical problem of how to improve the wearing comfort of a head-mounted support device.

[0051] In an embodiment of the present application, as shown in Figures 10 and 11, the portable and comfortable head-mounted support device includes: a front support device 10a, the front support device 10a is used to be worn on the forehead of a human body; a rear support device 20a, the rear support device 20a is used to be worn on the occipital region of a human body; a first connecting band 31a, the first connecting band 31a connecting the left end of the front support device 10a to the left end of the rear support device 20a; a second connecting band 32a, the second connecting band 32a connecting the right end of the front support device 10a to the right end of the rear support device 20a; and a third connecting band 33a, the third connecting band 33a connecting the upper side of the front support device 10a to the upper side of the rear support device 20a.

[0052] In this embodiment, the front support 10a is used to support and mount on the wearer's forehead, and the rear support 20a is used to support and mount on the wearer's occipital region. The front support 10a and the rear support 20a are connected via a first connecting band 31a, a second connecting band 32a, and a third connecting band 33a. A first connecting hole is provided at the left end of the front support 10a, and a second connecting hole is provided at the left end of the rear support 20a. The front end of the first connecting band 31a is connected to the first connecting hole, and the rear end is connected to the second connecting hole, thereby realizing the connection between the first connecting band 31a and the front support 10a and the rear support 20a. For the connection method between the second connecting band 32a and the third connecting band 33a and the front support 10a and the rear support 20a, please refer to the first connecting band 31a. The first connecting band 31a, the second connecting band 32a, and the third connecting band 33a are flexible connecting bands, and the lengths of the first connecting band 31a, the second connecting band 32a, and the third connecting band 33a are adjustable. The width of the third connecting band 33a can be set to 25mm to 30mm, which not only reduces the pressure exerted by the third connecting band 33a on the top of the wearer's head, but also allows the contact area between the third connecting band 33a and the wearer to be reasonably controlled.

[0053] The front wall of the front support device 10a can be used to attach an imaging device, allowing the wearer to wear the imaging device on their forehead to capture images of the surgical field. The front support device 10a and the rear support device 20a are connected to the first connecting band 31a, the second connecting band 32a, and the third connecting band 33a, simplifying the structure between the front support device 10a and the rear support device 20a and reducing the structural weight between the front support device 10a and the rear support device 20a. This not only ensures stable mounting of the head-mounted support on the wearer's head, but also reduces the weight of the head-mounted support device and improves wearing comfort.

[0054] Specifically, the radius of curvature of the rear side of the front support member 10a is 80 to 120 mm, and / or the radius of curvature of the front side of the rear support member 20a is 80 to 120 mm. Since the radius of curvature of the forehead and back of an adult's head is usually 80 to 120 mm, by setting the radius of curvature of the front support member 10a and the rear support member 20a to 80 to 120 mm, the fit between the front support member 10a and the rear support member 20a and the wearer's forehead and backhead can be improved, thereby improving wearing stability and comfort.

[0055] In practical application, the curvature of the rear side of the front support 10a is set to 120° to 160°, and / or the curvature of the front side of the rear support 20a is set to 120° to 160°. In this way, the front support 10a and the rear support 20a can be adapted to the curvature of the wearer's forehead and backhead, increasing the contact area between the front support 10a and the rear support 20a and the wearer's head, and further improving the wearing stability and comfort of the head-mounted support.

[0056] 12, the head-mounted support further includes a front flexible pad 41a, which is attached to the rear side of the front support 10a. The front flexible pad 41a may be a sponge pad or a silicone pad. The front flexible pad 41a is softer than the front support 10a and directly contacts the wearer's skin instead of the front support 10a, thereby improving the feel on the wearer's skin. The front flexible pad 41a can also be deformed to improve adhesion to the wearer's forehead, further improving the wearing stability of the head-mounted support.

[0057] 12, the head-mounted support further includes a rear flexible pad 42a, which is attached to the front side of the rear support 20a. The rear flexible pad 42a may be a sponge pad or a silicone pad. The rear flexible pad 42a is softer than the rear support 20a and comes into direct contact with the wearer's skin instead of the rear support 20a, thereby improving the feel on the wearer's skin. The rear flexible pad 42a can also be deformed to improve adhesion to the wearer's occipital region, thereby further improving the wearing stability of the head-mounted support.

[0058] For example, as shown in FIG. 11 , a mounting rack 21a is provided on the rear wall of the rear support 20a, and the mounting rack 21a is used to mount a control host or a mobile power supply. The control host or mobile power supply is used to electrically connect to the imaging device mounted on the front support 10a, thereby supplying power to the imaging device or controlling control signals. Mounting the control host or mobile power supply on the rear support 20a allows the control host or mobile power supply to be mounted on the head-mounted support, thereby improving the use efficiency of the head-mounted support. Furthermore, mounting the control host or mobile power supply on the rear support 20a can better balance the weight load on the wearer's forehead and occipital area, reducing strain on the wearer's neck.

[0059] 13, a connecting boss 11a is provided on the front wall of the front support 10a, and the head-mounted support further includes a first mounting seat 51 and a second mounting seat 52, which are switchably attached to the connecting boss 11a and are respectively used to mount different functional devices. The first mounting seat 51 and the second mounting seat 52 are detachably connected to the connecting boss 11a, with the first mounting seat 51 being used to mount a photographing device and the second mounting seat 52 being used to mount a lighting lamp, allowing the wearer to change between different mounting seats and install different functional devices according to their actual needs, further improving the usability of the head-mounted support.

[0060] 11 and 12, in actual application, a wiring groove 12a is recessed in the rear wall of the front support 10a, and a wiring hole 13a is opened in the front wall of the front support 10a, and the wiring hole 13a is connected to the wiring groove 12a. For example, when a photographing device is attached to the front wall of the front support 10a, the electrical connection wires of the photographing device extend through the wiring hole 13a into the wiring groove 12a. In this way, the wiring groove 12a functions to accommodate and shield the electrical connection wires, which not only prevents the exposure of the electrical connection wires from affecting the photographing field of view of the photographing device, but also prevents the electrical connection wires from being directly pinched between the front support 10a and the user's skin, ensuring a comfortable fit for the user.

[0061] The present application further provides a surgical field photography device, which includes a camera and a head-mounted support, the specific structure of which can be referred to in the above embodiments, and the surgical field photography device adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail herein, wherein the camera is attached to the front support 10a of the head-mounted support.

[0062] For example, the surgical field imaging device further includes a control host, which is attached to the rear wall of the rear support 20a of the head-mounted support and electrically connected to the imaging device. A user can control imaging with the imaging device through the control host. The surgical field imaging device further includes a pan-tilt mechanism, which is attached to the imaging device, and the control host can further control the rotation of the pan-tilt mechanism to adjust the imaging angle of the imaging device. In combination with the above embodiment of the mounting rack 21a, the control host is attached to the mounting rack 21a, thereby maintaining a constant relative position between the control host and the imaging device.

[0063] As shown in FIGS. 14 to 17, the present application further proposes a head-mounted support that solves the technical problem of how to improve the convenience of using a head-mounted support.

[0064] In an embodiment of the present application, as shown in Figures 14 and 15, the head-mounted support includes: a front support 10a, the front support 10a is used to be attached to the forehead of a human body; a rear support 20a, the rear support 20a is used to be attached to the occipital region of a human body; the front support 10a and the rear support 20a are connected via a connecting band 30a; and mounting seats 40a, the number of the mounting seats 40a is at least two, and each mounting seat 40a is attached to the front wall of the front support 10a in a switchable manner, and each mounting seat 40a is used to suitably attach a different functional device.

[0065] In this embodiment, the front support 10a is used to be supported and mounted on the wearer's forehead, and the rear support 20a is used to be supported and mounted on the wearer's occipital region. The front support 10a and the rear support 20a are connected via three connecting bands 30a, which include a first connecting band, a second connecting band, and a third connecting band. The first connecting band connects the left end of the front support 10a to the left end of the rear support 20a, the second connecting band connects the right end of the front support 10a to the right end of the rear support 20a, and the third connecting band connects the upper side of the front support 10a to the upper side of the rear support 20a. The first connecting band, the second connecting band, and the third connecting band are flexible connecting bands, and the lengths of the first connecting band, the second connecting band, and the third connecting band are adjustable. The width of the third connecting band is set to 25 mm to 30 mm, which reduces the pressure that the third connecting band exerts on the top of the wearer's head and allows for reasonable control of the contact area between the third connecting band and the wearer.

[0066] The number of mounting seats 40a is two, but may be three or more, and each mounting seat 40a is compatible with and attached to the front wall of the front support 10a, and each mounting seat 40a is adapted to accommodate different functional devices, such as a photographic device, a lighting lamp, or a magnifying glass.

[0067] A plurality of mounting seats 40a are selectively attached to the front support 10a, and different mounting seats 40a are provided for suitable attachment of different functional devices. In this way, by replacing the mounting seats 40a, the functional devices attached to the head-mounted support can be replaced. This allows the user to select the required functional device according to their actual needs and attach it to the corresponding mounting seat 40a. By attaching the mounting seat 40a to the front support 10a, the head-mounted support can interchangeably attach different functional devices, thereby improving the convenience of using the head-mounted support.

[0068] The mounting seat 40a is detachably connected to the front support 10a, and specifically may be a fitting connection or a plug connection, but is not limited thereto.

[0069] Specifically, as shown in Figures 15 to 17, a fixing groove 11b is opened in the front support 10a, a stopper rib 111a is protruding from the groove wall of the fixing groove 11b, a connection hook 41b is protruding from the mounting seat 40a, the connection hook 41b includes a connecting portion 411a and a locking portion 412a, the connection portion 411a connects the mounting seat 40a and the locking portion 412a, the connection hook 41b is detachably fitted into the fixing groove 11b, the locking portion 412a is provided between the stopper rib 111a and the groove bottom of the fixing groove 11b, and the locking portion 412a is in stopper contact with the stopper rib 111a.

[0070] The connection hook 41b is shaped like a "7," with the connection portion 411a connected to the mounting seat 40a and the locking portion 412a connected to the side of the connection portion 411a away from the mounting seat 40a. A stopper rib 111a is provided at the opening of the fixing groove 11b and protrudes from one groove wall of the fixing groove 11b. A locking space is formed between the stopper rib 111a and the groove bottom of the fixing groove 11b. When the connection hook 41b and the fixing groove 11b are mated, the connection hook 41b is located within the locking space and fits into the stopper rib 111a. The stopper rib 111a prevents the connection hook 41b from disengaging from the fixing groove 11b in the depth direction of the fixing groove 11b, thereby improving the connection stability between the mounting seat 40a and the front support 10a.

[0071] In actual application, as shown in Figures 15 and 16, a sliding groove 12b is further formed in the front support 10a, and the sliding groove 12b penetrates the fixed groove 11b. The width of the sliding groove 12b matches the width of the locking portion 412a, and the locking portion 412a slidably fits into the sliding groove 12b. The locking portion 412a can slide along the sliding groove 12b to the fixed groove 11b or can retreat from the fixed groove 11b to the sliding groove 12b.

[0072] When assembling the mounting seat 40a to the front support 10a, first, the connection hook 41b is placed in the sliding groove 12b, then the connection hook 41b is slid along the sliding groove 12b toward the fixing groove 11b until the locking portion 412a is inserted into the fixing groove 11b, and the locking portion 412a, which has entered the fixing groove 11b, is driven so as to abut against the stopper by the stopper rib 111a, thereby realizing the mounting and fitting of the connection hook 41b and the fixing groove 11b. When removing the mounting seat 40a, the connection hook 41b is slid along the fixing groove 11b toward the sliding groove 12b until the locking portion 412a is removed from the fixing groove 11b and inserted into the sliding groove 12b, and the connection hook 41b is released from the sliding groove 12b, thereby realizing the removal of the mounting seat 40a. By sliding the connection hook 41b, the mounting base 40a and the front support 10a can be attached and detached, which simplifies the process of attaching and detaching the mounting base 40a and the front support 10a and improves the convenience of attachment and detachment.

[0073] 15 to 17, a mounting boss 13b is protruded from the front wall of the support, and the fixing groove 11b and the sliding groove 12b are opened on the front end surface of the mounting boss 13b. The mounting boss 13b improves the structural strength of the mating portion between the front support 10a and the mounting seat 40a, prevents the front support 10a from being easily deformed or damaged after being subjected to mechanical stress generated in the process of attaching and detaching the mounting seat 40a, and can extend the overall service life of the head-mounted support.

[0074] The mounting boss 13b may be a circular boss, a square boss or a boss of another shape.

[0075] Specifically, as shown in FIG. 15, the mounting boss 13b is a circular boss, the sliding groove 12b and the fixing groove 11b extend in an arc shape, the shape and radial dimension of the mounting seat 40a correspond to the mounting boss 13b, and the extended shape of the connection hook 41b is compatible with the shapes of the sliding groove 12b and the fixing groove 11b.

[0076] The sliding groove 12b and the fixing groove 11b extend along the periphery of the front end surface of the mounting boss 13b, and when the connecting hook 41b slides from the sliding groove 12b into the fixing groove 11b or retreats from the fixing groove 11b into the sliding groove 12b, the mounting seat 40a undergoes rotational movement rather than linear movement. In this way, the space occupied by the movement of the mounting seat 40a during the attachment and detachment process is reduced, the trajectory of the attachment and detachment operation of the mounting seat 40a is simplified, and the convenience of attachment and detachment of the mounting seat 40a is further improved.

[0077] In actual application, there are two sets of sliding grooves 12b and fixing grooves 11b, and the two sets of sliding grooves 12b and fixing grooves 11b are spaced apart along the circumferential direction of the mounting boss 13b, and the number and positions of the connecting hooks 41b correspond to the sliding grooves 12b and fixing grooves 11b. The mounting seat 40a and the mounting boss 13b are connected to the two sets of connecting hooks 41b via the two fixing grooves 11b, which increases the connection positions between the mounting seat 40a and the mounting boss 13b and further improves connection stability.

[0078] For example, as shown in Figures 15 and 16, a raised portion 112a is provided protruding from the bottom of the fixing groove 11b, and the raised portion 112a presses the engaging portion 412a to fix it to the stopper rib 111a, thereby increasing the resistance when the connecting hook 41b is withdrawn from the fixing groove 11b. When the locking portion 412a passes over the raised portion 112a in the process of entering the fixing groove 11b, it must overcome the resistance of the raised portion 112a. After the locking portion 412a is fitted into the fixing groove 11b to a predetermined position, the raised portion 112a generates a pressing force against the locking portion 412a, so that the locking portion 412a is more tightly sandwiched between the raised portion 112a and the stopper rib 111a. In this way, the locking portion 412a is prevented from easily escaping from the fixing groove 11b. Even if the head-mounted support device is subjected to an impact force such as being dropped, the mounting base 40a will not easily come off the front support device 10a, thereby protecting the functional device attached to the mounting base 40a.

[0079] 16 and 17, a wiring hole 13a is provided in the center of the mounting boss 13b, and the wiring hole 13a penetrates the rear wall of the front support 10a. At least one mounting seat 40a has a wiring hole 42b that faces the wiring hole 13a. After the functional device is mounted on the mounting seat 40a, the electrical connection wires of the functional device can pass through the wiring hole 42b and the wiring hole 13a in sequence and extend to the rear side of the front support 10a, preventing the electrical connection wires from being exposed on the front side of the front support 10a and affecting the user's work.

[0080] In actual application, as shown in Figures 16 and 17, a wiring groove 12a is recessed in the area of ​​the rear wall of the front support 10a corresponding to the mounting boss 13b, and a wiring through-hole 141a is opened at the highest part of the groove wall of the wiring groove 12a. The wiring groove 12a serves to accommodate and isolate the electrical connection lines of the functional device, preventing the electrical connection lines from being directly pinched between the front support 10a and the user's skin, thereby ensuring a comfortable fit for the user.

[0081] The present application further provides a surgical field photography device, which includes a camera and a head-mounted support, the specific structure of which can be referred to in the above embodiments, and the surgical field photography device adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail herein, wherein the camera is mounted on one mounting seat 40a of the head-mounted support.

[0082] As shown in FIGS. 18 to 20, the present application further provides a head-mounted support that solves the technical problem of how to improve the use effect of a head-mounted support.

[0083] In an embodiment of the present application, as shown in Figures 18 to 20, the head-mounted support includes a front support 10a and a rear support 20a, the front support 10a is used to be attached to the front of the head, a wiring hole 13a is opened in the front wall of the front support 10a, a wiring groove 12a is recessed in the rear wall of the front support 10a, the wiring hole 13a passes through the wiring groove 12a, the front support 10a is used to attach a functional device, and the wiring hole 13a is used to extend the electrical connection wire of the functional device to the wiring groove 12a, and the rear support 20a is used to be attached to the back of the head, and the front support 10a and the rear support 20a are connected via a connection band 30a.

[0084] In this embodiment, the head-mounted support is used for the user to wear on the head, with the front support 10a being used to support and mount on the wearer's forehead and the rear support 20a being used to support and mount on the wearer's backhead. The front wall of the front support 10a is used to mount a functional device, allowing the wearer to wear the functional device on their forehead to assist with work. The functional device is electrically connected to a mobile power source or a control host via an electrical connection line. After the functional device is mounted on the front support 10a, the electrical connection line enters the wiring groove 12a through the wiring hole 13a, i.e., extends to the rear side of the front support 10a, and then extends from the rear side of the front support 10a until it is electrically connected to the mobile power source or the control host, with the remaining part of the electrical connection line still housed in the wiring groove 12a. The wiring groove 12a functions to accommodate and shield the electrical connection wires, preventing the electrical connection wires from being exposed and affecting the user's field of view or the field of view of the imaging device, and preventing the electrical connection wires from being directly pinched between the front support 10a and the user's skin, thereby ensuring comfort for the user.

[0085] For example, as shown in Figures 18 and 19, a mounting boss 13b is protruded from the front wall of the front support 10a, the mounting boss 13b is used to mount a functional device, the wiring hole 13a is opened in the mounting boss 13b, and the wiring groove 12a is opened in an area corresponding to the mounting boss 13b on the rear wall of the rear support 10.

[0086] The mounting boss 13b improves the structural strength of the mounting portion of the front support 10a for the supporting device and prevents the front support 10a from being easily damaged or deformed. The mounting boss 13b has a hollow structure, and the hollow portion is the wiring groove 12a, which increases the depth of the wiring groove 12a, increases the capacity of the wiring groove 12a, and improves the accommodation effect of the electrical connection wires.

[0087] 19 and 20, the wiring groove 12a has a groove bottom corresponding to the front end wall of the mounting boss 13b and groove walls corresponding to the peripheral wall of the mounting boss 13b, and the wiring hole 13a penetrates the groove bottom of the wiring groove 12a. The front end wall of the mounting boss 13b is used to mount a functional device, and after the functional device is mounted on the mounting boss 13b, its electrical connection wires can enter the wiring groove 12a from the groove bottom of the wiring hole 13a through the wiring hole 13a, thereby reducing the length of the electrical connection wires exposed from the wiring hole 13a and allowing more electrical connection wires to be fully accommodated within the wiring groove 12a.

[0088] 20, a wiring through-hole is provided in the wall of the wiring groove 12a, and the wiring through-hole penetrates the peripheral wall of the mounting boss 13b. After the electrical connection line enters the receiving groove through the wiring hole 13a, it extends from the wiring through-hole and protrudes from the receiving groove to be electrically connected to the mobile power supply or control host worn by the user or attached to the head-mounted support.

[0089] The number of wiring through holes may be one, two or more, and is not limited here.

[0090] 20 , the number of wiring through-holes is at least two, including a first wiring through-hole 121a and a second wiring through-hole 122a, where the first wiring through-hole 121a is located at the highest part of the groove wall of the wiring groove 12a and the second wiring through-hole 122a is located at the lowest part of the groove wall of the wiring groove 12a. The first wiring through-hole 121a and the second wiring through-hole 122a are arranged opposite each other in the vertical direction, and a user can select one of the first wiring through-hole 121a and the second wiring through-hole 122a to pass an electrical connection line through the wiring groove 12a and electrically connect to a mobile power supply or a control host. For example, when a user is wearing a mobile power supply or a control host, the electrical connection line passes through the wiring groove 12a via the second wiring through-hole 122a and extends downward, easily connecting electrically to the mobile power supply or control host worn by the wearer. When a user wears a mobile power supply or a control host on the rear support 20a, the electrical connection line passes through the first wiring through-hole 121a, extends around the headband, and electrically connects to the mobile power supply or the control host on the rear support 20a. In this way, the first wiring through-hole 121a and the second wiring through-hole 122a can meet different wiring needs of users and improve the convenience of using the head-mounted support.

[0091] For example, as shown in FIG. 19 , a mounting rack 40b is provided on the rear wall of the rear support 20a, and the mounting rack 40b is used to mount a control host or a mobile power supply. Mounting the control host or mobile power supply on the mounting rack 40b allows the control host or mobile power supply to be mounted on the head-mounted support, improving the use efficiency of the head-mounted support. Mounting the control host or mobile power supply on the rear support 20a also balances the load on the wearer's forehead and back, reducing the strain on the wearer's neck. The electrical connection line passes through the wiring through-hole and extends rearward to be electrically connected to the control host or mobile power supply, thereby facilitating an electrical connection between the control host or mobile power supply.

[0092] Specifically, the connection band 30a is provided with a wiring fixing structure for restraining the electrical connecting wires of the functional device, which can extend along the connection band 30a to the rear support 20a. The wiring fixing structure restrains the electrical connecting wires to the connection band 30a, restricting and protecting the electrical connecting wires, thereby keeping them close to the connection band 30a and preventing them from being easily caught.

[0093] In actual application, as shown in FIG. 18, the number of the connecting bands 30a will be multiple, including a first connecting band, a second connecting band, and a third connecting band, wherein the first connecting band connects the left end of the front support 10a to the left end of the rear support 20a, the second connecting band connects the right end of the front support 10a to the right end of the rear support 20a, and the third connecting band connects the upper edge of the front support 10a to the upper edge of the rear support 20a, and the wiring fixing structure is provided on the third connecting band.

[0094] When the head-mounted support device is worn on the user's head, the third connecting band is abutted against the top of the user's head, and the electrical connecting wire can be extended along the third connecting band to the rear support device 20a, i.e., via the top of the wearer's head to the rear support device 20a. In this way, the electrical connecting wire can be held in a high position, preventing the electrical connecting wire from being easily caught, and improving the stability of electrical conduction of the functional device.

[0095] The present application further provides a surgical field photography device, which includes a camera and a head-mounted support, the specific structure of which can be referred to in the above embodiments, and since this surgical field photography device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects caused by the technical solutions of the above embodiments, which will not be described in detail here, wherein the camera is mounted on the front support 10a of the head-mounted support, and the electrical connection wire of the camera extends through the wiring hole 13a of the head-mounted support and into the wiring groove 12a of the head-mounted support.

[0096] Specifically, the surgical field imaging device further includes a control host, which is attached to the rear support 20a of the head-mounted support, and the electrical connection wire of the imaging device extends along the connecting band 30a of the head-mounted support and is electrically connected to the control host. A user can control imaging with the imaging device through the control host. The surgical field imaging device further includes a pan-tilt mechanism, and the imaging device is attached to the pan-tilt mechanism, and the control host can further control the rotation of the pan-tilt mechanism to adjust the imaging angle of the imaging device. When combined with the above embodiment of the mounting rack 40b, the control host is attached to the mounting rack 40b, and the relative positions of the control host and the imaging device can be kept constant.

[0097] The voltage required for operation of a photography device (including the photography mechanism and pan-tilt mechanism) is usually greater than 5V (e.g., 9V, 12V), and when a power supply device (mobile power supply or adapter) is directly connected to the photography device to supply power, it outputs 5V by default, which does not reach the voltage required for operation of the photography device. The conventional solution is to install a battery in the control box of the photography device, and the power supply device charges the battery in the control box through an interface, which then powers the photography device, but this method increases the cost and weight of the control box.

[0098] 21 to 24, in response to the above problems of the camera control box, the applicant of the present application proposes a new camera control box circuit, which can effectively reduce the cost and weight of the camera control box. The camera control box circuit of the present application is mainly applied to the camera control box of a camera device.

[0099] In this embodiment, the camera control box circuit 100 includes a first Type-C interface 10b, a power output interface 20b, a first voltage step-down module 30b and a PD (Power Delivery) trick module 40c.

[0100] Here, the first Type-C interface 10b is used to electrically connect to the power supply device 200, which may be, for example, a mobile power supply, a power adapter, etc.

[0101] The power supply output interface 20b is electrically connected to the camera module 300 and is used to supply power for the operation of the camera module 300, where the camera module 300 includes parts such as a camera lens, a camera pan-tilt mechanism, etc.

[0102] The first step-down module 30b has an input end and an output end, the input end of the first step-down module 30b is electrically connected to the VBUS pin 11 of the first Type-C interface 10b, and the output end of the first step-down module 30b is electrically connected to the power supply output interface 20b.

[0103] The PD trick module 40c is electrically connected to the first Type-C interface 10b and performs protocol communication with the power supply device 200.

[0104] In the camera control box circuit 100 of this embodiment, an electrical connection between the PD trick module 40c and the first Type-C interface 10b is added, so that the PD trick module 40c performs protocol communication with the power supply device 200 through the first Type-C interface 10b to negotiate the PD protocol, and the power supply device 200 outputs a voltage exceeding 5V based on the PD protocol negotiated with the PD trick module 40c (i.e., the VBUS pin 11 of the first Type-C interface 10b outputs a voltage exceeding 5V). For example, the power supply device 200 outputs a voltage of 9V, 12V, 15V, 18V, 20V, etc. based on the PD protocol negotiated with the PD trick module 40c. In this way, the input end of the first step-down module 30b receives the voltage (such as 9V, 12V, or 15V) output by the power supply device 200 based on the PD protocol from the VBUS pin 11 of the first Type-C interface 10b, and further steps down the voltage received from the VBUS pin 11 of the first Type-C interface 10b to the operating voltage (e.g., 7.8V) required by the camera module 300, allowing the camera module 300 to operate normally.

[0105] The technical solution of the camera control box circuit 100 of this embodiment includes a first Type-C interface 10b electrically connected to the power supply device 200, a power supply output interface 20b electrically connected to the camera module 300, a first step-down module 30b and a PD trick module 40c, wherein the input end of the first step-down module 30b is electrically connected to the VBUS pin 11 of the first Type-C interface 10b, and the output end of the first step-down module 30b is electrically connected to the power supply output interface 20b, and the PD trick module 40c is connected to the first Type-C interface 10b, and performs protocol communication between the first Type-C interface 10b and the power supply device 200 via the PD trick module 40c, so that the power supply device 200 outputs a voltage exceeding 5V (such as 9V, 12V, or 15V) according to the negotiated PD protocol, and the input terminal of the first step-down module 30b receives an input voltage exceeding 5V, so that the first step-down module 30b steps down the received voltage and directly supplies it to the camera module 300 via the power output interface 20b, allowing the camera module 300 to operate normally. Compared with the prior art solution of adding a battery to the camera control circuit, the technical solution of this embodiment eliminates the need for a battery, reducing the cost and weight of the camera control box and the volume required for the camera control box, making the camera control box lighter and more compact, and more convenient to install and carry.

[0106] Here, the first step-down module 30b can be a step-down switching regulator, which can stabilize the voltage output from the output terminal of the first step-down module 30b and further stabilize the operation of the camera module 300. Here, the step-down switching regulator can be, for example, an MP9943GQ chip, but of course, it can also be another chip with the same function.

[0107] 22 and 23, in some embodiments, the camera control box circuit 100 further includes a power management module 50a, a main control chip 70, and a second step-down module 60.

[0108] Here, the power management module 50a includes a voltage input terminal 51a, an enable terminal 52a, a first voltage output terminal 53 that is always on, and a plurality of second voltage output terminals 54. When a voltage is input to the input terminal of the power management module 50a, the output terminal of the first voltage output terminal 53 outputs a voltage without being controlled by the enable terminal 52a.

[0109] The main control chip 70 includes a power control unit 71 and multiple power pins 72. The first voltage output terminal 53 is electrically connected to the power control unit 71 to supply power to the power control unit 71. The multiple power pins 72 are electrically connected to the multiple second voltage output terminals 54 in a one-to-one relationship. The power control unit 71 is electrically connected to the enable terminal 52a of the power pipeline module to control the output on / off of the multiple second voltage output terminals 54. In some embodiments, the multiple second voltage output terminals 54 output voltages of different magnitudes, for example, 0.9V, 1.5V, 1.8V, and 3.0V, which respectively supply power to different power supply pins 72 of the main control chip 70 and function as different power supplies (e.g., including core power, memory power, and IO port power).

[0110] The input end of the second step-down module 60 is electrically connected to the VBUS pin 11 of the first Type-C interface 10b, and the output end of the second step-down module 60 is electrically connected to the voltage input end 51a of the power management module 50a.

[0111] In the solution of this embodiment, the second step-down module 60 receives the voltage (e.g., 9V, 12V, etc.) output by the power supply device 200 according to the PD protocol from the VBUS pin 11 of the first Type-C interface 10b, steps down the received voltage to a specified voltage (e.g., 4.8V), and outputs it to the input terminal of the power management module 50a. After receiving the voltage output from the second step-down module 60, the power management module 50a outputs a predetermined voltage (e.g., 1.8V) from its first voltage output terminal 53 to the power control unit 71 of the main control chip 70. The power control unit 71 then starts to operate and outputs a corresponding signal to the enable terminal 52a of the power management module 50a, causing the power management module 50a to start outputting from each second voltage output terminal 54, which supplies voltage to each power supply pin 72 of the main control chip 70. Each power supply pin 72 of the main control chip 70 supplies power to each corresponding device component, thereby controlling the camera control box to start and operate normally.

[0112] Here, the power control unit 71 of the main control chip 70 controls the electrical signal at the enable terminal 52a of the power management module 50a to cause the power management chip to stop outputting each second voltage output terminal 54, thereby cutting off the power supply to each power supply pin 72 of the main control chip 70.

[0113] Here, the second step-down module 60 is a single-output step-down converter, such as a SY8623 chip, although other chips with the same functions may also be used. The power management module 50a may be an I2225 chip or other chips with the same functions.

[0114] Here, the main control chip 70 may adopt the SOC of the camera control box circuit 100, such as V39M.

[0115] In the technical solution of this embodiment, the voltage of the VBUS pin 11 of the first Type-C interface 10b is boosted to exceed 5V through the PD trick module 40c, but through the voltage step-down process of the second step-down module 60, the voltage is still reduced to the level required by the main control chip 70 and the power management module 50a, so as not to affect the normal operation of the main control chip 70 and the power management module 50a.

[0116] 23 , in some embodiments, the camera control box circuit 100 further includes a second Type-C interface 80, which is used to connect to an external device 400 (e.g., a writing device, a storage device, etc.). The main control chip 70 further includes a USB 2.0 unit 73, in which a VBUS pin 81 of the second Type-C interface 80 is electrically connected to the voltage input terminal 51a of the power management module 50a, and a D+ pin and a D− pin of the second Type-C interface 80 are electrically connected to the USB 2.0 unit 73 for data transmission with the USB 2.0 unit 73.

[0117] In this embodiment, an external device 400, such as a storage device or a writing device, is connected to the second Type-C interface 80 to transmit data to the USB 2.0 unit 73 of the main control chip 70, thereby enabling the writing device to write programs to the main control chip 70 or the transmission of data such as photo data and video data between the storage device and the camera control box. When the external device 400 is connected to the second Type-C interface 80 and no power supply device 200 is connected to the first Type-C interface 10b, the external device 400 can supply power to the power management module 50a via the VBUS pin 81 of the second Type-C interface 80, so that the power management module 50a can supply power to the main control chip 70 and related devices via the first voltage output terminal 53 and each second voltage output terminal 54, allowing the camera control box to normally transmit data.

[0118] In some embodiments, a diode is connected in series between the VBUS pin 81 of the second Type-C interface 80 and the voltage input terminal 51a of the power management module 50a, with the anode of the diode electrically connected to the VBUS pin 81 of the second Type-C interface 80, i.e., the diode provides unidirectional conduction between the VBUS pin 81 of the second Type-C interface 80 and the voltage input terminal 51a of the power management module 50a. This prevents the voltage stepped down by the second step-down module 60 from being output to the external device 400 through the VBUS pin 81 of the second Type-C interface 80 when the first Type-C interface 10b is connected to the power supply device 200 and the second Type-C interface 80 is connected to the external device 400, thereby maintaining a longer power supply time for the power supply device 200.

[0119] 24, in some embodiments, the PD trick module 40c includes an HUSB238 chip 41c, the XIN pin 411b of the HUSB238 chip 41c being electrically connected to the VBUS pin 11 of the first Type-C interface 10b, and the D+, D-, CC1, and CC2 pins of the HUSB238 chip 41c being correspondingly electrically connected to the D+, D-, CC1, and CC2 pins of the first Type-C interface 10b. The HUSB238 is a highly integrated USB PD power receiving device chip (PDSink, also known as a PD trick chip) with a transmittable rated power of up to 100W, compliant with PD3.0V1.3 and Type-CV1.4, and supporting charging protocols such as BC1.2DCP, CDP, and SDP.

[0120] In this embodiment, the HUSB238 chip 41c is powered via the VBUS pin 11 of the first Type-C interface 10b, and the HUSB238 chip 41c communicates and performs protocol negotiation with devices connected to the first Type-C interface 10b via the D+, D-, CC1, and CC2 pins. By using the HUSB238 chip 41c, the VBUS pin output of the first Type-C interface 10b can meet various voltage needs, and the required voltage can be set according to needs, thereby supporting the operation power supply of different camera modules 300.

[0121] In some embodiments, the ISET pin 412b of the HUSB238 chip 41c is grounded via a first resistor R1, which is a resistor for setting the current magnitude, i.e., the magnitude of the output current of the VBUS pin 11 of the first Type-C interface 10b. For example, the first resistor R1 may be 4.53 kΩ, 7.5 kΩ, 10.5 kΩ, 13.7 kΩ, 16.5 kΩ, 19.6 kΩ, or 22.6 kΩ, and the corresponding output current magnitudes of the VBUS pin 11 of the first Type-C interface 10b are 1.5 A, 1.75 A, 2 A, 2.25 A, 2.5 A, 2.75 A, and 3 A, respectively. In some embodiments, the VSET pin 413a of the HUSB238 chip 41c is grounded via a second resistor R2, which is a resistor for setting a voltage magnitude, i.e., setting the magnitude of the output voltage of the VBUS pin 11 of the first Type-C interface 10b. For example, the second resistor R2 may be 6.04 kΩ, 10 kΩ, 14 kΩ, or 17.8 kΩ, and the corresponding output voltage magnitudes of the VBUS pin 11 of the first Type-C interface 10b are 9 V, 12 V, 15 V, and 18 V, respectively. The user can selectively set the magnitudes of the first resistor R1 and the second resistor R2 according to specific power requirements. For example, if the first resistor R1 is selected to be 10.5 kΩ and the second resistor R2 is selected to be 10 kΩ, the output power of the VBUS pin of the first Type-C interface 10b is 24 W.

[0122] In some embodiments, the ISET pin 412b of the HUSB238 chip 41c may be set to a floating state, in which case the HUSB238 chip 41c identifies all PD protocols of the power supply device 200, and the VBUS pin 11 of the first Type-C interface 10b outputs a current based on the maximum output current that the power supply device 200 can output.

[0123] In some embodiments, the VSET pin 413a of the HUSB238 chip 41c may be set to a floating state, in which case the HUSB238 chip 41c will identify all PD protocols of the power supply device 200, and the VBUS pin 11 of the first Type-C interface 10b will output a voltage based on the maximum output voltage that the power supply device 200 can output. Of course, in other embodiments, the PD trick module 40c may include other model numbers of USB PD powered device chips.
