DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0026] It should be understood that the terms "include" and "comprising" used in the specification and claims of the present disclosure indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0027] It should also be understood that the terms used in this disclosure are only for the purpose of describing specific embodiments and are not intended to limit the disclosure. As used in this disclosure and claims, the singular forms of "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise. It should also be further understood that the term "and / or" used in this disclosure and claims refers to any combination of one or more of the associated listed items and all possible combinations, including these combinations.

[0028] As used in this specification and claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0029] In the field of existing surveillance camera equipment, a camera assembly with multiple rotating joints can provide a 360° surveillance field of view, thereby eliminating the blind spot problem that occurs when using a surveillance camera assembly with a single rotating axis, and can reduce the overall number of surveillance camera equipment actually used to a certain extent, so as to reduce the cost of use and maintenance. However, in existing surveillance camera equipment, the rotation drive device is often exposed due to more joints, which increases the failure rate. Or the space occupied by the camera assembly as a whole is too large, which makes it difficult to arrange and has poor aesthetics. In addition, various existing camera equipment for 360° monitoring often causes the internal wires to be tangled and pulled due to the rotation of the rotating assembly, resulting in reduced connection effect or even failure. In view of this, multiple embodiments of the present disclosure provide a monitoring assembly that achieves 360° blind spot-free monitoring with a simpler and more compact structure, and has better maintenance performance and reduced use costs.

[0030] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 3 , Figure 1 An exemplary perspective view of a monitoring assembly according to some embodiments of the present disclosure is shown. Figure 2 An exemplary exploded view of a monitoring assembly of some embodiments of the present disclosure is shown, Figure 3 An exemplary exploded view of a monitoring assembly of some embodiments of the present disclosure is shown.

[0032] In some embodiments of the present disclosure, a monitoring assembly is provided, including a base, a rotating assembly, and a swinging camera assembly. The rotating assembly includes a rotating drive mechanism and a support portion fixedly connected to the rotating drive mechanism, and the support portion has a through-going wire hole. The swinging camera assembly includes a swinging drive mechanism and a camera assembly fixedly connected to the swinging drive mechanism. The rotating drive mechanism is drivingly connected to the base to drive the support portion to rotate relative to the base, the swinging drive mechanism is drivingly connected to the support portion to drive the camera assembly to rotate relative to the support portion, and the rotating axis of the camera assembly is colinearly arranged with the axis of the wire hole.

[0033] As shown in the figure, in this embodiment, the monitoring assembly includes a rotating assembly 20, a swing camera assembly 10 and a base 30. The rotating assembly 20 includes a rotating drive mechanism 21 and a rotating frame 22 driven to rotate by the rotating drive mechanism 21, and the rotating frame 22 includes a support portion 221 extending axially parallel to the rotation output shaft 211 of the rotating assembly 20. The swing camera assembly 10 includes a swing drive mechanism 11, a swing frame 12 and a camera assembly 90, the swing drive mechanism 11 includes a swing body 112 and a swing output shaft 111 rotating relative to the swing body 112, the swing frame 12 is fixedly connected to the swing body 112, the support portion 221 extends into the inside of the swing frame 12, the swing output shaft 111 is fixedly connected to the support portion 221, and the camera assembly 90 is fixedly arranged on the swing frame 12, and the axial direction of the swing output shaft 111 is perpendicular to the axial direction of the rotation axis of the rotating assembly 20. The rotation drive mechanism 21 includes a rotation body 212 and a rotation output shaft 211. The rotation body 212 is fixedly connected to the rotation frame 22, and the rotation output shaft 211 is rotationally connected to the base 30. The base 30 is connected to the rotation frame 22 in a relatively rotatable manner. With the help of the base 30, the monitoring component can be installed on a fixed object such as a desktop or a wall.

[0034] Specifically, see also Figure 2 and Figure 4 , Figure 4An exemplary cross-sectional view of a monitoring assembly of some embodiments of the present disclosure is shown. In this embodiment, the interior of the rotating frame 22 is a hollow structure, and the rotating drive mechanism 21 is a rotating motor, wherein the motor main body of the rotating motor is a rotating body 212, and the output shaft of the rotating motor is a rotating output shaft 211 extending outward from one side of the rotating body 212. The rotating output shaft 211 extends toward the side away from the swing camera assembly 10 and is drivingly connected to the base 30. The rotating body 212 is fixed to the rotating frame 22 by a shape fit or a bolt connection inside the rotating frame 22. Thus, when the rotating output shaft 211 of the rotating drive mechanism 21 rotates, the rotating body 212 will rotate relative to the base 30 with the rotating frame 22. The support portion 221 extends from the side of the rotating frame 22 away from the base 30, and is roughly formed into a long strip. The end of the support portion 221 away from the base 30 is also provided with a connection bayonet for matching and connecting with the swing output shaft 111.

[0035] The interior of the swing frame 12 is also a hollow structure, and the swing drive mechanism 11 is arranged inside the swing frame 12, and the swing drive mechanism 11 is also a rotating motor. The swing body 112 of the swing drive mechanism 11 and the swing frame 12 are fixed to each other by means of shape matching or bolt connection, and its swing output shaft 111 extends in a direction perpendicular to the axis of the rotation output shaft 211. In this embodiment, the swing drive mechanism 11 has a mounting flange, which is fixedly connected to the inner wall of the swing frame 12 by bolts. The support portion 221 of the rotating frame 22 extends from the swing frame 12 to the inside of the swing frame 12 toward the side of the rotating frame 22, and the swing output shaft 111 extends into the connecting bayonet on the support portion 221 along the above-mentioned direction perpendicular to the axis of the rotation output shaft 211. Thus, when the swing output shaft 111 rotates relative to the swing body 112, the swing body 112 can rotate relative to the rotating frame 22 together with the swing frame 12, so that the camera assembly 90 installed on the swing frame 12 can adjust its angle along two mutually perpendicular rotation directions to achieve 360° rotation monitoring. And its structure is simple, without exposed joints or driving components, which reduces the difficulty of maintenance. In addition, in this embodiment, a flat mouth structure that matches the shape of the connecting bayonet is formed on the swing output shaft 111. It can be understood by those skilled in the art that the swing output shaft 111 can also be fixed to the support portion 221 by bolt connection or the like.

[0036] In this embodiment, the rotating frame 22, the swing frame 12 and the base 30 are all configured to have a circular cross-sectional outer contour, and the three are concentrically arranged along the axis. The diameters of the cross-sectional contours of the rotating frame 22, the swing frame 12 and the base 30 are the same, so that the whole forms a regular cylindrical appearance. As a result, the overall structure of the monitoring component is more compact, the required installation space is smaller, and because it has an arc-shaped outer contour as a whole, it is not easy to interfere with other objects such as cables when rotating. However, it can be understood by those skilled in the art that the present disclosure does not limit the specific external structure of the camera assembly 90. For example, the rotating frame 22, the swing frame 12 and the base 30 can also be configured to have a square or polygonal profile cross section.

[0037] Further, the rotating frame 22 includes a first guide portion 2112, and the swing frame 12 includes a second guide portion 1211. The first guide portion 2112 and the second guide portion 1211 are matched in shape and can slide and rotate with each other along the rotation direction of the swing output shaft 111. Specifically, in this embodiment, the first guide portion 2112 is the axial outer end surface of the swing frame 12 adjacent to the rotating frame 22, and correspondingly, the second guide portion 1211 is the axial outer end surface of the rotating frame 22 adjacent to the swing frame 12. The first guide portion 2112 is a concave arc surface, and the second guide portion 1211 is a convex arc surface. The arc surfaces of the first guide portion 2112 and the second guide portion 1211 are concentrically arranged. In addition, a guide groove 1212 is also arranged on the second guide portion 1211, and the guide groove 1212 passes through the axial outer end surface of the rotating frame 22, so that the support portion 221 can extend into the guide groove 1212 and connect with the swing output shaft 111. The guide groove 1212 is configured to extend along the direction of relative movement between the support portion 221 and the swing frame 12 , and its length is configured to prevent the swing frame 12 from interfering with the swing frame 12 when the swing frame 12 rotates relative to the support portion 221 .

[0038] It can be understood by those skilled in the art that, although the above describes a structure in which the first guide portion 2112 is set as a concave arc surface and the second guide portion 1211 is set as a convex arc surface, the present disclosure does not limit the actual shapes and matching relationship of the first guide portion 2112 and the second guide portion 1211. For example, in some embodiments not shown, the first guide portion is a convex arc surface, and the second guide portion is a concave arc surface, or the first guide portion is a spherical surface, and the second guide portion is a ball socket that matches the shape of the first guide portion, and the spherical surfaces or arc surfaces of the first guide portion and the second guide portion are coaxially or concentrically arranged, and it is only necessary to ensure that the first guide portion and the second guide portion are arranged to be able to rotate relative to each other in a shape-matched manner. Therefore, when the swing frame 12 rotates relative to the rotating frame 22, the adjacent parts of the two will be able to maintain a stable, large-area contact or overlap, reducing the width of the joint joint during the rotation process, thereby reducing the probability of cables or debris being caught in the joint gap when adjusting the angle. It also reduces the risk of debris or dust entering the interior of the monitoring component through the joint gap when stationary at a certain angle, thereby further reducing the cost of use and maintenance.

[0039] In addition, see again Figure 4 In this embodiment, a first channel 2210 and a wire hole 2213 are provided inside the support portion 221. The wire hole 2213 penetrates the support portion 221 in a direction parallel to the rotation axis of the swing frame 12, and a second channel 1110 is provided inside the swing output shaft 111. The first channel 2210 is communicated with the wire hole 2213, and the wire hole 2213 is communicated with the second channel 1110, so as to connect the wire from the first channel 2210 to the swing drive mechanism 11 through the second channel 1110. The first channel 2210 first extends from the inner surface of the axial end of the rotating frame 22 facing the swing frame 12 in a direction parallel to the rotation axis of the rotating frame 22 toward the swing frame 12, and the wire hole 2213 extends from the end of the support portion 221 away from the base 30 along the axial direction of the swing output shaft 111 of the swing drive mechanism 11 to the connecting bayonet. The swing output shaft 111 is hollow and defines a second channel 1110 extending along its axis, so that when the swing output shaft 111 is fixedly connected to the connecting bayonet, one axial end of the second channel 1110 is aligned with and connected to the wire hole 2213 at the end of the support portion 221, so that the wire hole 2213 is colinearly arranged with the rotation axis of the swing frame 12, and the other axial end of the second channel 1110 extends to the interior of the swing drive mechanism 11.

[0040] Thus, the wires used to drive and control the rotation of the swing drive mechanism 11 (as well as the wires used to control the driving camera assembly 90) can be introduced into the swing drive mechanism 11 through the first channel 2210, the wire hole 2213 and the second channel 1110 to be electrically connected to the corresponding electric control terminal. By setting the wire hole for passing the wire to be aligned with the rotation axis of the swing frame 12, when the swing frame 12 rotates, the relative position of the first channel 2210 and the swing output shaft 111 remains unchanged, and the wires in the first channel 2210 will only be twisted around its axial direction with the rotation of the swing body 112, and will not swing significantly along the rotation direction of the swing body 112. Thus, the risk of the wires being wound or pulled when the driving mechanism rotates can be reduced, and the connection effect of the connector can be ensured. Moreover, since the wires are hidden inside other components, the overall structure is more compact, which is conducive to the miniaturization of the device.

[0041] See also Figure 4 and Figure 5 , Figure 5 An exemplary stereogram of the base part assembly of the monitoring assembly of some embodiments of the present disclosure is shown, wherein some parts of the swing camera assembly 10 and the rotating assembly are removed to clearly show the internal structure. In this embodiment, the rotating assembly 20 also includes a driving gear 23 and a fixed gear 33, the driving gear 23 is fixedly connected to the rotating output shaft 211, the fixed gear 33 is fixedly arranged on the base 30, and the driving gear 23 and the fixed gear 33 are meshed with each other to transmit the drive. The rotating frame 22 has a rotating driving cavity 220 for accommodating the rotating body 212 inside, the bottom side of the rotating frame 22 cooperates with the base 30 in an axial limiting manner along the rotating output shaft 211, and a gear cavity 330 for accommodating the fixed gear 33 and the driving gear 23 is defined between the rotating frame 22 and the base 30.

[0042] Specifically, see also Figures 4 to 6 , Figure 6 An exemplary exploded view of the rotating assembly of the monitoring assembly of some embodiments of the present disclosure is shown. The rotating frame 22 includes a first shell 2201 and a second shell 2202 that are fixed to each other. The first shell 2201 is adjacent to the swing camera assembly 10, and is roughly in the shape of a hollow cylinder with one side open, while the second shell 2202 is roughly formed in the shape of a plate, and a snap-fit ​​structure 224 is provided on the side facing the first shell 2201, and the snap-fit ​​structure 224 is used to match the shape of the rotating drive mechanism 21 to be fixedly connected thereto. The size of the outer periphery of the second shell 2202 adjacent to the side of the first shell 2201 is set to form an interference fit with the size of the inner periphery of the radial side wall of the first shell 2201, thereby, the second shell 2202 can at least partially extend into the inner side of the first shell 2201, and be fixedly connected to the first shell 2201 by means of an interference fit.

[0043] The bottom of the first shell 2201 is also provided with a positioning bayonet 2201a, and the outer peripheral side of the second shell 2202 is provided with a positioning block 2202a protruding outward along its outer periphery. After the first shell 2201 and the second shell 2202 are sleeved and fixed to each other, the positioning block 2202a extends into the interior of the positioning block 2202a, and the positioning bayonet 2201a and the positioning block 2202a are matched in shape, thereby preventing relative rotation between the two. The first shell 2201 and the second shell 2202 jointly enclose a rotation drive cavity 220 for accommodating the rotation drive mechanism 21, thereby preventing the rotation drive mechanism 21 from being disturbed or contaminated by the outside world. In addition, in order to enhance the connection strength with the rotation drive mechanism 21, the second shell 2202 is also provided with a fixing hole aligned with the mounting threaded hole on the rotation drive mechanism 21, so as to further fix it with the help of bolts. In addition, on the outer peripheral side of the second shell 2202, there are multiple guide blocks 2202c protruding away from the base 30 toward the first shell 2201. One side of the guide block 2202c is coplanar with the outer peripheral side of the second shell 2202, and a guide surface inclined radially inward is formed on the end thereof away from the base 30. The guide surface is used to guide the first shell 2201 when it is sleeved on the outside of the second shell 2202 to facilitate installation and maintenance.

[0044] The base 30 is generally formed into a hollow cylinder with one side open, and the inner size and shape of the cylindrical side wall thereof correspond to the outer size and shape of the second shell 2202. Thus, when the rotating frame 22 and the base 30 are engaged with each other, the second shell 2202 at least partially extends into the inner part of the cylindrical side wall of the base 30, and the cylindrical side wall of the base 30, the axial end wall of the base 30 and the second shell 2202 define the gear chamber 330. A plurality of limiting protrusions 32 are provided on the inner surface of the cylindrical side wall of the base 30, and correspondingly, an inwardly concave annular limiting groove 222 is also provided on the outer peripheral surface of the second shell 2202. The plurality of limiting protrusions 32 can extend into the annular limiting groove 222 of the second shell 2202 and engage therewith, so that the rotating frame 22 can be axially limited relative to the base 30 and can rotate relative to each other.

[0045] In this embodiment, a plurality of release grooves 2202d are further provided on the cylindrical side wall of the base 30, and the plurality of release grooves 2202d penetrate the cylindrical side wall in the radial direction, and extend along the side of the cylindrical side wall axially away from the rotating frame 22 to the edge of the cylindrical side wall, and at least partially pass through the annular limiting groove 222 on the side facing the rotating frame 22. Thus, the annular limiting groove 222 and the corresponding cylindrical side wall portion are divided into a plurality of segments, and when the base 30 is docked with the rotating frame 22, due to the reduced structural strength of the plurality of segments, when the plurality of segments abut against the limiting protrusion 32, they can more easily deform radially to avoid the limiting protrusion 32, thereby further reducing the difficulty of installation and maintenance.

[0046] The rotary output shaft 211 of the rotary drive mechanism 21 is eccentrically arranged relative to the rotary axis of the rotary frame 22, and the second shell 2202 is provided with an output shaft hole 2202b penetrating the plate surface thereof, and the rotary output shaft 211 extends into the gear cavity 330 along the output shaft hole 2202b and is fixedly connected with the driving gear 23. The fixed gear 33 is fixedly arranged on the side of the axial end wall of the base 30 facing the rotary frame 22, and is arranged at the central part of the axial end wall. The driving gear 23 and the fixed gear 33 are gears meshing with each other. When the rotary output shaft 211 rotates, its rotational action causes the driving gear 23 to rotate around the fixed gear 33 on the outer periphery of the fixed gear 33, thereby driving the rotary frame 22 to rotate. At this time, the axle of the fixed gear 33 is the rotation axis of the rotating frame 22, and by setting the fixed gear 33 at the center of the base 30, the rotating frame 22 and the fixed gear 33 can rotate concentrically, reducing the lateral movement of the rotating frame 22 during rotation and reducing the probability of collision with external objects.

[0047] With the help of the gear cavity 330 formed by the second shell 2202 and the base 30, the gear transmission part of the monitoring component is enclosed and protected by the external shell. Therefore, after applying lubricants such as grease to the drive gear 23 and the fixed gear 33, the corresponding lubricant will be stably maintained in the gear cavity 330, reducing the risk of lubricant leakage or contamination, and also reducing the probability of external dust or debris contacting the gear meshing part, causing lubricant contamination or even gear jamming. In addition, compared with direct drive using the motor drive shaft, the use of gear transmission drive can adjust the transmission ratio, thereby obtaining greater torque or faster speed according to actual needs. And fixing the fixed gear 33 to the base 30 can make the force generated by the transmission mechanism during the transmission process directly borne by the base 30, making the rotating mechanism more stable.

[0048] Furthermore, a third channel 3310 extending along the axis of the rotating frame 22 and penetrating the base 30 is provided in the fixed gear 33, and a wire entry hole 2120 is provided on the rotating body 212, and the third channel 3310 is aligned with the wire entry hole 2120. The wires used to control the driving camera assembly 90, the wires used to drive the swing drive mechanism 11, and the wires used to drive the rotation drive mechanism 21 can all be introduced into the interior of the monitoring assembly with the help of the third channel 3310. Similar to the functions of the first channel 2210 and the second channel 1110, by setting the channel for passing the wire to be aligned with the axle of the fixed gear 33, when the rotating frame 22 rotates, the relative position of the fixed gear 33 and the wire entry hole 2120 on the rotating body 212 remains unchanged. It can reduce the risk of the wire being wound or pulled when the rotating frame 22 rotates, ensure the stable connection of the connector, and the structure is more compact, which is conducive to the miniaturization of the device.

[0049] Through the monitoring assembly disclosed in the present disclosure and in multiple embodiments, the drive and drive transmission mechanism structures of the various drive parts for adjusting the shooting angle of the camera assembly are simpler. In addition, by arranging the rotation drive mechanism for driving the rotating frame body to rotate in the rotating frame body, and arranging the support part of the rotating assembly in the swing frame body to drive the swing frame body to rotate, while completing 360° rotation monitoring, the active joint parts for driving are all hidden inside the structural parts, reducing the probability of failures such as jamming due to external influences, and reducing the difficulty and cost of maintenance.
