[0002] In order to realize the richness of monitoring capability, a gimbal-mounted camera is developed on the basis of a common spherical camera, which can mount more cameras on the gimbal.

[0003] The conventional installation method is to mount the camera device on the gimbal using nuts or locking mechanisms, for example, it can be hung on both sides of the gimbal, for example, it can be locked at the end of the rotating shaft.

[0004] The conventional fixing method will cause load concentration, and the barrel of the camera device is prone to cracking after being subjected to vibration or torsional moment. When the weights on both sides of the gimbal are uneven, the overall stress of the gimbal-mounted camera is unbalanced, and the overall strength is also affected. In addition, cables are needed for communication between different cameras, and when the local or overall structural strength is insufficient, the safety protection of the cables is also threatened.

[0010] In some embodiments, the first group of screws is an even number of screws, and the first group of screws is evenly distributed in the circumference.

[0011] In this way, the load of the camera is evenly dispersed through the even number of screws, and the torque and shear force generated by the camera are evenly distributed to the multiple screw connections, avoiding stress concentration in local positions and causing the overall strength to decrease; the uniform stress can be maintained when the main shaft is rotated to different angles.

[0013] In this way, the torsional moment borne by the main shaft can be reduced, and the overall overturning moment can be reduced.

[0014] In some embodiments, the camera includes a barrel, the barrel being provided with a first opening and a second opening opposite in the first direction, the first opening being directed towards the mounting frame and exposing the main shaft in the projection in the first direction, the first set of screws being arranged around the first opening, and the second opening exposing the first set of screws in the projection in the first direction.

[0015] In this way, the first set of screws can be easily screwed through the second opening; the connection state of the camera and the main shaft can be controlled through the second opening and the first opening.

[0016] In some embodiments, the camera further includes a camera head, the field of view direction of the camera head intersecting the first direction; the barrel includes a reinforcing rib and four side walls arranged in a rectangle around the camera head, the first opening being provided in one side wall, the reinforcing rib extending from the first opening in the field of view direction, and the second opening being provided in another side wall, the second opening having a spacing from the edge of the another side wall.

[0017] In this way, the field of view direction can be tilted according to the rotation of the main shaft; the reinforcing rib helps to prevent the side walls of the barrel from being cracked or otherwise abnormal.

[0018] In some embodiments, the barrel includes a middle cavity, a first cover, a second cover, and a third cover, the extension direction of the middle cavity intersecting the first direction, the first opening and the second opening being provided in the middle cavity, the first cover being used to cover the second opening, and the second cover and the third cover being oppositely arranged in the extension direction of the middle cavity to block the middle cavity.

[0019] In this way, the components can form a closed cavity, which has better resistance to torsional force and shear force.

[0020] In some embodiments, one of the two cameras includes a thermal imaging camera head, and the thermal imaging camera head is arranged in the second cover; the other camera includes a visible light camera head and a support, and the visible light camera head is arranged in the middle cavity through the support.

[0042] Reference Figure 1 , Figure 1 A binocular camera in an embodiment of the present application is shown. In an exemplary embodiment, the binocular camera 1000 includes a mounting seat 1, a mounting frame 2, and a camera 3. The binocular camera 1000 can be provided with one camera 3 on the left and one camera 3 on the right. The binocular camera 1000 can also be attached with more cameras 3.

[0043] For the convenience of description, a space rectangular coordinate system XYZ is established, and the X-axis direction can be referred to as the left-right direction, the Z-axis direction can be referred to as the up-down direction, and the Y-axis direction can be referred to as the front-rear direction.

[0044] In combination Figure 2 and Figure 3 As shown, the mounting seat 1 can be a pan-tilt head. The mounting seat 1 includes a mounting shell 11 and a base 12. The mounting shell 11 is rotationally connected to the base 12, and the rotation axis can be along the Z-axis direction, so that the mounting shell 11 can rotate relative to the base 12 in the XY plane, and the mounting shell 11 can be rotated to different angles in space. The rotating action can be controlled by a driving device arranged in the mounting shell 11.

[0045] Exemplarily, the mounting seat 1 includes the mounting shell 11 and a main shaft 10 penetrating the mounting shell 11 in a first direction. The main shaft 10 is rotationally connected to the mounting shell 11 and can move with the mounting shell 11. When the mounting seat 1 is a pan-tilt head, as Figure 1As shown, the main shaft 10 can be in a position parallel to the X-axis direction. The main shaft 10 can also rotate with the mounting shell 11 to a position intersecting, for example, perpendicular to the X-axis direction. The binocular camera 1000 of the embodiment of the application can also realize other actions and can be kept in a selected posture.

[0046] The mounting frame 2 is arranged across the mounting base 1. The mounting frame 2 can be of an integral structure or can be assembled and fixed by multiple components. Referring to Figure 2 and Figure 3 , the mounting frame 2 includes two side plates 21 arranged opposite to each other at both ends of the main shaft 10 and capable of rotating with the main shaft 10. The mounting frame 2 can also include at least one top plate 22 fixed between the two side plates 21 and capable of transmitting force to synchronize the movement of the two side plates 21. The entire mounting frame 2 is fixed to the main shaft 10 and can rotate with the main shaft 10. The force at both ends of the main shaft 10 is transmitted not only by the main shaft 10 itself but also by the mounting frame 2, and the force at both ends of the main shaft 10 is more balanced.

[0047] The top plate 22 can have a spacing from the mounting shell 11 to ensure that the mounting frame 2 rotates with the main shaft 10 relative to the mounting base 1.

[0048] The two camera devices 3 are arranged opposite to each other in the mounting frame 2 along the first direction, and each camera device 3 is fixed to the corresponding side plate 21. The diameter of the main shaft 10 is difficult to design large due to the structural design, and the side plate 21 provides a larger mounting area for the camera device 3, which helps to reduce the force concentration of the camera device 3. By arranging the mounting frame 2, the force at both ends of the main shaft 10 is balanced, and the overall structural strength of the binocular camera 1000 is good.

[0049] The camera device 3 is connected to the corresponding side plate 21 by the corresponding first set of screws 1010 arranged around the main shaft 10. The binocular camera 1000 has a compact structure. The camera device 3 can pitch in the plane parallel to the Z-axis direction relative to the mounting shell 11 with the side plate 21 and the main shaft 10. When the camera device 3 rotates at different angles, the moment will be different, and the arrangement of the first set of screws 1010 disperses the connection points of the camera device 3 and the side plate 21, which helps to disperse the force, adapts to different use requirements, and prolongs the service life.

[0050] Referring to Figure 3 and Figure 4 , the first set of screws 1010 needs to be screwed into the first set of screw holes 2110 provided in the side plate 21, and the screw holes can be threaded holes. Alternatively, a screw rod is fixed to the side plate 21, and the camera device 3 is locked to the screw rod by a nut.

[0051] The first group of screws 1010 can be an even number of screws, and the number can be no less than six, for example, eight screws. The first group of screws 1010 can be evenly distributed circumferentially. The load of the camera 3 is evenly dispersed by an even number of screws, and the torque, shear force, etc. generated by the camera 3 is evenly distributed to the multiple screw connections, avoiding stress concentration in local positions and causing the overall strength to decrease; when turning to different angles, uniform stress can be maintained.

[0052] Referring to Figures 1 to 3 , the side plate 21 is connected to the main shaft 10 by the corresponding second group of screws 1020. Referring to Figure 4 , the side plate 21 can be provided with a second group of screw holes 2120, which can be vias. The second group of screws 1020 is an even number of screws, and the number can be no less than six, for example, six. The second group of screws 1020 is evenly distributed circumferentially.

[0053] Referring to Figure 1 , the center of gravity of the camera 3, the first group of screws 1010, and the second group of screws 1020 are coaxially arranged with the main shaft 10, specifically, the center of gravity of the camera 3 can be located on the extension line of the axis of the main shaft 10. When the main shaft 10 rotates, the center of gravity of the camera 3 can always be coaxial, and the first group of screws 1010 and the second group of screws 1020 balance the force and torque, which can reduce the torsional torque borne by the main shaft 10 and reduce the overturning torque of the binocular camera 1000 as a whole.

[0054] Referring to Figure 1 and Figure 5 , the camera 3 includes a barrel 31. Referring to Figure 6 and Figure 7 , the barrel 31 is provided with a first opening 301 and a second opening 302 opposite in the first direction, and the two openings are provided on the two side walls 3111 opposite to each other. The cross section of the barrel 31 can have a substantially rectangular outer contour, and can have other shapes. A portion of the outer wall surface of the barrel 31 facing the mounting frame 2 is a plane, which can better fit the side plate 21.

[0055] The first opening 301 is provided on the side wall 3111 facing the mounting frame 2, and the projection of the first opening 301 in the first direction exposes the main shaft 10, specifically, the second group of screws 1020. When mounting the barrel 31, a screwdriver can be used to pass through the second opening 302, and then each of the second group of screws 1020 is screwed at the first opening 301 to control the connection state of the camera 3 and the main shaft 10. The first opening 301 can be a rounded rectangle, which reduces the occupied area and is also beneficial to reduce stress concentration.

[0056] The barrel 31 can be provided with a third set of screw holes 3110, which can be through holes, for corresponding screwing of the first set of screws 1010. The third set of screw holes 3110 surrounds the first opening 301 with a spacing. The first set of screws 1010 surrounds the first opening 301, so that the force of the camera 3 is evenly transmitted to the side plate 21.

[0057] The projection of the second opening 302 along the first direction exposes the first set of screws 1010. As shown, the second opening 302 is larger than the first opening 301, making it easy to screw each of the first set of screws 1010 through the second opening 302. The second opening 302 can also be a rounded rectangle, or other smooth profile shape. Figure 7

[0058] The second opening 302 has a spacing from the edge of the side wall 3111 where it is located. When the adjacent side walls 3111 are connected by a circular arc, the second opening 302 has a spacing from the circular arc connection. The first opening 301 is smaller than the second opening 302, and the first opening 301 also has a spacing from the edge of the side wall 3111 where it is located.

[0059] Referring to Figure 1 , the camera 3 also includes a camera 32. Each camera 3 can include at least one camera 32, which can be of the same type or all be different types. Figure 1 In the embodiment shown, the field of view direction of the camera 32 can be along the Y-axis direction, of course, there will be changes after rotation. The field of view direction of the camera 32 intersects the first direction, for example, perpendicular.

[0060] Referring to Figure 5 , the barrel 31 includes a middle cavity 311, a first cover 312, a second cover 313, and a third cover 314. The components of the barrel 31 can be integrally formed, and the components can be fixed to each other by screwing, clamping, gluing, etc. The joint can be sealed, for example, to ensure waterproof and dustproof.

[0061] The side wall 3111 can be used to form the middle cavity 311. Figures 6 to 8 The structure of the middle cavity 311 is shown. The extension direction of the middle cavity 311 intersects the first direction, and the first opening 301 and the second opening 302 are provided in the middle cavity 311.

[0062] The first cover 312 is used to cover the second opening 302. The second opening 302 is provided with a fourth set of screw holes 3120, which can be threaded holes, for fixing the first cover 312 with corresponding screws. The second cover 313 and the third cover 314 are oppositely arranged along the extension direction of the middle cavity 311 to block the middle cavity 311. The second cover 313 can be referred to as a rear cover, and the third cover 314 can be referred to as a front cover. The camera direction of the camera 32 can be towards the front. The components of the barrel 31 can form a closed cavity, thereby better resisting torsional force and shear force.​

[0063] Referring to Figure 7 and Figure 8 The barrel 31 includes the reinforcing ribs 3112. The middle cavity 311 can include the reinforcing ribs 3112. Exemplarily, the middle cavity 311 includes a part of the reinforcing ribs 3112. The second cover 313 and the third cover 314 are respectively provided with other parts of the reinforcing ribs 3112. The reinforcing ribs 3112 of the barrel 31 can extend to the front and rear end faces, ensuring the structural strength of the entire barrel 31.

[0064] The reinforcing ribs 3112 can be arranged at the first opening 301, for example, wrapping the side edges of the first opening 301. The reinforcing ribs 3112 extend from the first opening 301 along the field of view direction, which helps to improve the strength of the side wall 3111 connected to the mounting frame 2 in the barrel 31, preventing the side wall 3111 from being broken or other abnormalities under uniform load.

[0065] Referring to Figure 8 The barrel 31 includes four side walls 3111 arranged in a rectangle, which can be used to constitute the middle cavity 311. In combination with Figure 1 The four side walls 3111 are arranged around the camera 32. The side wall 3111 in which the first opening 301 is arranged can be provided with reinforcing ribs 3112, and the side wall 3111 in which the second opening 302 is arranged can be provided with other reinforcing ribs 3112, so as to improve the overall structural strength.

[0066] In combination with Figure 1 The camera device 3 shown on the left can include a thermal imaging camera, and the thermal imaging camera is arranged on the second cover 313, i.e., the front cover, of the camera device 3. Figure 1 The camera device 3 shown on the right can include a visible light camera and a bracket 33, and the visible light camera is arranged in the middle cavity 311 of the barrel 31 through the bracket 33, for example, on the lower side wall 3111.

[0067] The binocular camera 1000 can be provided with a thermal imaging camera and a visible light camera, and can also be provided with other types of cameras 32. The binocular camera 1000 can realize at least two camera modes. According to different cameras 32, different connection modes can be arranged to ensure the structural reliability of each camera device 3, so as to ensure normal shooting.

[0068] The binocular camera 1000 further comprises a cable 1030. The two cameras 3 communicate through the cable 1030. The main shaft 10 has a through hole 101 through in the first direction. The cable 1030 is arranged in the through hole 101, so that one camera 3 can be electrically connected to the other camera 3 through the cable 1030. The cable 1030 can be protected by the main shaft 10, avoiding exposure of the cable 1030 outside the mounting seat 1 and the mounting frame 2, which is conducive to avoiding damage and avoiding electromagnetic interference of communication. The material of the main shaft 10 can be metal; the material of the mounting frame 2 and the material of the barrel 31 can also be metal.

[0069] When the binocular camera 1000 has an uneven overall weight bias, the mounting frame 2 cooperates with the main shaft 10 to improve the stress condition, so that the overall strength rises. The main shaft 10 and the two barrels 31 can be relatively stationary to a certain extent, and the cable 1030 is also relatively stationary in the main shaft 10 and the two barrels 31, avoiding the cable 1030 being twisted during the movement of the binocular camera 1000, ensuring reliable electrical connection and stable communication.

[0070] The main shaft 10 can be a segmented structure.

[0071] The technical features of the above disclosed embodiments can be combined in any manner.
