[0095] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0096] In order to solve the problems in the prior art, the present invention provides a camera system, which includes at least two camera assemblies, and the angles of the camera assemblies relative to the camera body are adjustable to achieve a larger shooting range in combination.

[0097] like Figure 1 to Figure 2 As shown, one embodiment of the present invention provides a camera system, comprising:

[0098] A camera body 1, the camera body 1 is formed into a cylindrical shape around a central axis L extending in the longitudinal direction, a first camera assembly 2 is hung at the bottom of the camera body 1, and a first optical axis of the first camera assembly 2 forms an angle with the central axis L;

[0099] The bolt bracket 3 extends horizontally and radially outward from the side wall of the camera body 1. The second camera assembly 4 is hung on the end of the bolt bracket 3 via the first transmission assembly 5 so as to have the freedom of horizontal rotation relative to the camera body 1 and the bolt bracket 3. The second camera assembly 4 includes a second camera base 41 and a second camera head 42 mounted on the second camera base 41.

[0100] The first transmission assembly 5 comprises:

[0101] A first bearing 51, the first bearing 51 rotates around the longitudinal direction, and the first bearing 51 rotatably connects the second camera base 41 to the bolt bracket 3;

[0102] A first damping assembly 52, the first damping assembly 52 is coaxially arranged with the first bearing 51, and the first damping assembly 52 comprises a first stationary portion 521 fixedly connected to the bolt bracket 3 and a first rotating portion rotating synchronously with the first bearing 51, and the first damping assembly 52 is used to provide a first damping force to limit the horizontal rotation of the first bearing 51, wherein the first stationary portion 521 and the bolt bracket 3 remain relatively stationary;

[0103] The first synchronous wheel 53, the second camera assembly 4 is driven by the first synchronous wheel 53 to rotate horizontally relative to the gun bracket 3;

[0104] The first rotating part includes: a screw 522 defining a first central axis, a first elastic sheet 523 and a plurality of first friction sheets 524 sleeved on the first central axis, a first rotating member 526 fastened to the first synchronous wheel 53, and a first adjusting nut / nut 525 threadedly matched with the outer surface of the first central axis 522, wherein the first stationary part 521 is sleeved on the first central axis 522, the first elastic sheet 523, the first friction sheet 524, and the first stationary part 521 are limited between the first rotating member 526 and the first adjusting nut / nut 525, the first rotating member 526 is fixedly connected to the first bearing 51, the first elastic sheet 523 has an elastic deformation amount along the axial direction of the first central axis 522, and the first damping force responds to the spacing between the first adjusting nut 525 and the first rotating member 526;

[0105] The first elastic piece 523 is isolated from the first adjusting nut 525 , the first stationary portion 521 , and the first rotating member 526 .

[0106] In this embodiment, the first transmission assembly 5 is constructed as follows: when the second camera assembly 4 rotates horizontally, the first rotating member 526 rotates horizontally synchronously around the first center axis under the drive of the first synchronous wheel 53. The horizontal rotation of the first rotating member 526 is limited by the first stationary part 521 that is stationary relative to the gun bracket 3 and is subjected to the longitudinal downward elastic force applied by the first spring piece 523, thereby damping the horizontal rotation of the second camera assembly 4.

[0107] In this embodiment, the first camera assembly 2 is hung at the bottom of the camera body 1, and the gun bracket 3 extends horizontally outward from the side wall of the camera body 1 to hang the second camera assembly 4. It may include a pair of gun brackets 3, which extend radially outward along a diameter direction of the camera body 1 to hang a pair of second camera assemblies 4. Each second camera assembly 4 is hung at the end of a gun bracket 3 via a first transmission assembly 5 to have the freedom of horizontal rotation relative to the camera body 1 and the gun bracket 3. The pair of second camera assemblies 4 can face different directions in the horizontal direction to form a larger horizontal field of view together with the first camera assembly 2.

[0108] The damping of the rotating joint part of the first transmission assembly 5 mainly provides a certain self-locking force to prevent the device from rotating freely when the power is off (the motor is not powered on), causing the camera image to shake. Therefore, the damping stability of the rotating joint part is very important.

[0109] Generally, the revolute joints with damping are mostly provided with a structure having an annular spring sheet, for example, Figure 4b In the form of the first shrapnel shown in , the annular shrapnel has an elastic deformation in the axial direction of the rotating joint, and generates friction by adjusting the extrusion of the nut, and the friction between the shrapnel and the rotating part in the rotating joint generates damping force. Usually, the shrapnel is generally installed between relatively rotating parts. Since the shrapnel participates in the rotation, there are problems such as wear and unstable damping force. In addition, different damping forces need to be adjusted when replacing cameras of different weights, which requires changing the type of shrapnel, compression amount, structural size, etc., resulting in poor adaptability and versatility of the rotating joint. Furthermore, the shrapnel of the traditional structure participates in both compression and friction, and its motion life, reliability, and stability are not high. After a long time, there are problems such as abnormal noise, weakened damping force, and jamming.

[0110] In this embodiment, the first transmission assembly 5 includes a first bearing 51 for providing a rotational connection and a first damping assembly 52 for providing a damping force. The outer retaining ring (fixed part) of the first bearing 51 is fixed to the bolt bracket 3 by screws, and the inner retaining ring (rotating part) of the first bearing 51 is fixedly connected to the second camera base 41 of the second camera assembly 4, so that when the inner retaining ring of the first bearing 51 rotates, the second camera base 41 is driven to rotate relative to the outer retaining ring. The first bearing 51 rotates around the longitudinal direction to realize the horizontal rotation of the second camera base 41 around the longitudinal direction.

[0111] The first damping assembly 52 includes a first stationary portion 521 fixedly connected to the bolt support 3 and a first rotating portion that rotates synchronously with the first bearing 51, wherein the structure of the first rotating portion is as follows: Figures 4a to 4c As shown, the first central shaft 522 provides a support center, which is formed in the shape of a circular shaft, and the first elastic piece 523 for providing a compressive deformation, the first friction plate 524 for providing friction damping, the first adjusting nut 525 for adjusting the compressive deformation, the first rotating member 526 for connecting with the first bearing 51, and the first stationary part 521 for providing a fixed support and damping fulcrum are all sleeved on the first central shaft 522, and the first elastic piece 523, the first friction plate 524, the first adjusting nut 525, and the first rotating member 526 all rotate synchronously with the first central shaft 522. The first adjusting nut 525 is threadedly connected to the outer surface of the first central shaft 522 to adjust the deformation of the first elastic piece 523.

[0112] The first stationary part 521 is fixedly connected to the bolt bracket 3 and is stationary, serving as a damping fulcrum. When the first rotating member 526 is driven by the first synchronous wheel 53 to rotate horizontally around the first center axis, the first damping force is provided to the first bearing 51 to limit its horizontal rotation by adjusting the contact friction between the first rotating part and the first stationary part 521.

[0113] In this embodiment, the first elastic sheet 523 is not in direct contact with the hard structures such as the first adjustment nut 525, the first stationary part 521, and the first rotating member 526, but is isolated from the hard structures by the wear-resistant first friction sheet 524 to avoid elastic failure caused by friction during the rotation process. The first elastic sheet 523 adjusts the locking force through the first adjustment nut 525, and the friction force is provided by the first friction sheet 524, that is, the rotation damping effect is provided, and the rotation damping effect is provided by the friction between the first rotating part and the first stationary part 521.

[0114] Specifically, Figure 3As shown, the bolt bracket 3 has a hollow cavity, the first transmission assembly 5 is located in the hollow cavity, and the second camera base 41 includes a second top box 411 located on the top thereof. The second top box 411 penetrates from the bottom surface of the bolt bracket 3 into the hollow cavity to be fixedly connected to the rotating part of the first bearing 51.

[0115] In this embodiment, if Figure 4c As shown, the first central axis 522 has a through hole penetrating along its axial direction, and the cable connected to the second camera 42 extends from the first central axis 522 into the hollow cavity.

[0116] The first transmission assembly 5 of this embodiment is formed as a wire-passing damping structure, and the first central axis 522 not only provides rotation support, but also provides a channel for the cable to pass through, and the cable for the second camera 42 can be directly extended into the hollow cavity of the gun bracket 3 through the through hole of the first central axis 522, and then extended into the camera body 1. Then the control mainboard for the second camera 42 can also be unnecessary to be arranged in the housing of the second camera 42, but transferred to the interior of the camera body 1 with a larger space.

[0117] In this embodiment, in the axial direction of the first central axis 522, the first stationary portion 521 is located between a pair of first friction plates 524. This ensures that both the upper and lower surfaces of the first stationary portion 521 can fully contact the friction surface. The first friction plate 524 is usually made of a material that is softer than a hard structure such as metal or plastic to provide greater friction and higher wear resistance.

[0118] like Figure 4b As shown, the outer surface of the first central shaft 522 has a first limiting notch 5221, and the first rotating member 526, the first elastic sheet 523 and the first friction sheet 524 all have limiting notches corresponding to the first limiting notch 5221, so as to rotate synchronously with the first central shaft 522. The first limiting notch 5221 is formed as a plane that is recessed inward along the circumferential surface of the first central shaft 522, so that the first rotating member 526, the first elastic sheet 523 and the first friction sheet 524 can rotate synchronously with the first central shaft 522 through the angle structure formed by the plane and the circumferential surface.

[0119] In this embodiment, in the axial direction of the first center axis 522, the first spring plate 523 is located between a pair of first friction plates 524 to ensure that the upper and lower surfaces of the first spring plate 523 are isolated from the hard structure, and only the part involved in the compression is protected by the first friction plate 524 without being subject to the friction of the hard structure.

[0120] In a specific example, if Figure 4cAs shown, the end of the first center axis 522 has a first step portion 5222 for limiting the first rotating member 526, and the first rotating member includes three first friction plates 524, and the three first friction plates 524 are respectively isolated between the first rotating member 526 and the first stationary portion 521, between the first stationary portion 521 and the first elastic plate 523, and between the first elastic plate 523 and the first adjusting nut 525.

[0121] Thus, each hard structure, namely, the first stationary portion 521 , the first rotating member 526 , and the first elastic sheet 523 , is clamped between a pair of first friction sheets 524 to be isolated from other hard structures.

[0122] Combination Figure 3 and Figure 4b As shown, the first stationary portion 521 includes: a central ring portion sleeved on the first central axis 522, and a pair of connecting arms 5211 extending radially outward from the central ring portion, and the pair of connecting arms 5211 are fixedly connected to the hollow cavity of the bolt bracket 3.

[0123] Among them, a first radial direction formed by a pair of connecting arms 5211 relative to the first central axis 522 and a second radial direction formed by the gun bracket 3 relative to the camera body 1 form an acute angle.

[0124] That is, the extension direction of the pair of connecting arms 5211 forms an acute angle with the extension direction of the bolt bracket 3, so as to reduce the space occupied by the connecting arms 5211 in the hollow cavity of the bolt bracket 3 and reduce the external dimensions of the bolt bracket 3.

[0125] like Figure 3 As shown, the first transmission assembly 5 includes:

[0126] A first synchronous wheel 53, the first synchronous wheel 53 is fixedly connected to the first bearing end cover 511 of the first bearing 51, so as to rotate synchronously with the first bearing 51;

[0127] The second camera assembly 4 includes: a first horizontal motor for driving the first bearing 51 to rotate around the longitudinal direction via the first synchronous wheel 53, and the first horizontal motor is installed in the hollow cavity.

[0128] The first horizontal motor for driving the second camera assembly 4 to rotate horizontally is not arranged inside the second camera 42, but is arranged in the hollow cavity of the gun bracket 3, which can help to reduce the volume of the second camera 42 and improve the heat dissipation effect of the second camera 42.

[0129] Figure 5 FIG. 2 is a partial schematic diagram of a second embodiment of a camera system of the present invention. Figure 2 and Figure 5As shown, the second camera assembly 4 is hung on the end of the gun bracket 3 via the first transmission assembly 5 so as to have the freedom of horizontal rotation relative to the camera body 1 and the gun bracket 3, and is installed on the second camera base 41 via the second transmission assembly 6 so as to have the freedom of pitch rotation relative to the camera body 1 and the gun bracket 3.

[0130] Wherein, the second camera base 41 comprises:

[0131] A second horizontal portion 412, a second top box 411 connected to the center of the second horizontal portion 412;

[0132] A pair of second side walls 413, the pair of second side walls 413 respectively extend longitudinally from the ends of the second horizontal portion 412, and the second camera 42 is installed between the pair of second side walls 413 via the second transmission assembly 6 to have the freedom of pitch and rotation relative to the camera body 1 and the bolt bracket 3;

[0133] Combination Figures 6a to 6c As shown, the second transmission assembly 6 includes:

[0134] A second bearing 61, the second bearing 61 rotates around a horizontal direction, and the second bearing 61 rotatably connects the second camera 42 to the second side wall 413;

[0135] A second damping assembly 62, the second damping assembly 62 comprises a second stationary portion 621 fixedly connected to the second bearing 61 and a second rotating portion fixedly connected to the second camera 42, the second damping assembly 62 is used to provide a second damping force to limit the pitch rotation of the second bearing 61, and the axial direction of the second stationary portion 621 extends in the horizontal direction;

[0136] A second synchronous wheel 63, through which the second camera 42 can pitch and rotate relative to the second side wall 413;

[0137] The second rotating part includes: a second elastic piece 622 and a plurality of second friction pieces 623 sleeved on the second stationary part 621, a second rotating member 624 rotating synchronously with the second camera 42, and a second adjusting nut 625 threadedly matched with the outer surface of the second stationary part 621, wherein the second elastic piece 622 and the second friction piece 623 are limited between the second rotating member 624 and the second adjusting nut 625, the second rotating member 624 is fixedly connected to the second camera 42, the second elastic piece 622 has an elastic deformation amount along the axial direction of the second stationary part 621, and the second damping force responds to the spacing between the second adjusting nut 625 and the second rotating member 624;

[0138] The second elastic piece 622 is isolated from the second adjusting nut 625 , the second stationary portion 621 , and the second rotating member 624 .

[0139] In this embodiment, the second transmission assembly 6 is constructed as follows: when the second camera 42 pitches and rotates, the second rotating member 624 synchronously pitches and rotates around the second center axis under the drive of the second synchronous wheel 63, and the pitch rotation of the second rotating member 624 is limited by the second stationary part 621 that is stationary relative to the second side wall 413 and is subjected to the horizontal inward elastic force exerted by the second elastic sheet 622, thereby damping the pitch rotation of the second camera 42.

[0140] The structure of the second transmission assembly 6 is similar to that of the first transmission assembly 5, both of which have a friction plate structure added, so that the second spring plate 622 does not directly contact the hard structures such as the second adjustment nut 625, the second stationary part 621, and the second rotating member 624, but is isolated from the hard structures by the wear-resistant second friction plate 623 to avoid elastic failure caused by friction during rotation. The second spring plate 622 adjusts the locking force through the second adjustment nut 625, and the friction force is provided by the second friction plate 623, that is, a rotation damping effect is provided, and the rotation damping effect is provided by the friction between the second rotating part and the second stationary part 621.

[0141] Among them, Figure 1 and Figure 5 As shown, the second camera 42 has a second housing, and the second transmission assembly 6 is located in the second housing.

[0142] The connection mode of the second transmission assembly 6 is different from that of the first transmission assembly 5. Specifically, the outer retaining ring (second stationary part) of the second bearing 61 is fixed to the second housing 421 through a vertical bearing pressure plate and screws, and the second stationary part 621 passes through the inner retaining ring (second rotating member 624) of the second bearing 61 and is pressed by the second synchronous wheel 63 and screws, so as to rotate synchronously with the second bearing 61.

[0143] The second damping assembly 62 includes a second stationary portion 621 fixedly connected to the second side wall 413 and a second rotating portion fixedly connected to the second housing 421 of the second camera 42 .

[0144] The difference in connection mode lies in the difference in connection mode of the second bearing 61. Specifically, the fixed portion of the second bearing 61 is connected to the second housing 421 to be rotated, and the rotating portion is connected to the second damping assembly 62. The fixed portion of the first bearing 51 is connected to the bolt bracket 3, and the rotating portion is connected to the second camera base 41 to be rotated.

[0145] Accordingly, the second transmission assembly 6 comprises:

[0146] A second synchronous wheel 63, the second synchronous wheel 63 is fixedly connected to the second bearing 61 to rotate synchronously with the second bearing 61;

[0147] The second camera assembly 4 includes a second vertical motor for driving the second bearing 61 to rotate around a horizontal direction via a second synchronous wheel 63 , and the second vertical motor is installed in the second housing.

[0148] The second vertical motor is installed in the second housing to drive the second bearing 61 to rotate around the horizontal direction via the second synchronous wheel 63, thereby realizing the pitch rotation of the second camera 42 relative to the camera body 1 and the gun bracket 3.

[0149] like Figures 6a to 6c As shown, the second stationary portion 621 has a second step portion 6211 protruding radially outward, and the second rotating portion includes three second friction plates 623, which are respectively isolated between the second step portion 6211 and the second rotating member 624, between the second rotating member 624 and the second elastic plate 622, and between the second elastic plate 622 and the second adjusting nut 625.

[0150] In this embodiment, in the axial direction of the second stationary portion 621, the second spring plate 622 is located between a pair of second friction plates 623 to ensure that the upper and lower surfaces of the second spring plate 622 are isolated from the hard structure, and only the part involved in the compression is protected by the second friction plate 623 without being subject to friction from the hard structure.

[0151] Thus, each hard structure, namely, the second step portion 6211 of the second stationary portion 621 , the second rotating member 624 , and the second elastic sheet 622 , is clamped between a pair of second friction sheets 623 to be isolated from other hard structures.

[0152] In a specific example, the outer surface of the second stationary part 621 has a second limiting notch 6212 , and the second rotating member 624 , the second elastic plate 622 and the second friction plate 623 all have limiting notches corresponding to the second limiting notch 6212 to rotate synchronously with the second stationary part 621 .

[0153] It can be seen from the above technical solution that in this embodiment, the first camera assembly 2 is hung at the bottom of the camera body 1, and the gun bracket 3 extends horizontally outward from the side wall of the camera body 1 to hang the second camera assembly 4. Among them, it can include a pair of gun brackets 3, and the pair of gun brackets 3 extend radially outward along a diameter direction of the camera body 1 to hang a pair of second camera assemblies 4. Among them, each second camera assembly 4 is hung on the end of a gun bracket 3 via the first transmission assembly 5, so as to have the freedom of horizontal rotation relative to the camera body 1 and the gun bracket 3. The pair of second camera assemblies 4 can face different directions in the horizontal direction to form a larger horizontal field of view together with the first camera assembly 2.

[0154] The first spring sheet 523 is not in direct contact with the hard structures such as the first adjustment nut 525, the first stationary part 521, and the first rotating member 526, but is isolated from the hard structures by the wear-resistant first friction sheet 524 to avoid elastic failure caused by friction during rotation. The first spring sheet 523 adjusts the locking force through the first adjustment nut 525, and the friction force is provided by the first friction sheet 524, that is, the rotation damping effect is provided, and the rotation damping effect is provided by the friction between the first rotating part and the first stationary part 521.

[0155] The second elastic sheet 622 is not in direct contact with the hard structures such as the second adjusting nut 625, the second stationary part 621, and the second rotating member 624, but is isolated from the hard structures by the wear-resistant second friction sheet 623 to avoid elastic failure caused by friction during the rotation process. The second elastic sheet 622 adjusts the locking force through the second adjusting nut 625, and the friction force is provided by the second friction sheet 623, that is, the rotation damping effect is provided, and the rotation damping effect is provided by the friction between the second rotating part and the second stationary part 621.

Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention, such as combination, division or repetition of features, should be included in the scope of protection of the present invention.
