Abstract

This utility model relates to the field of video surveillance technology, providing a security camera rotating assembly and a camera. The security camera rotating assembly includes a camera bracket lower shell, a driving component, a ball bearing fixing bracket, a bearing, and a driven rotating component. The camera bracket lower shell provides a mounting base for the driving component, bearing, and driven rotating component. The camera bracket lower shell has mounting holes located in the middle of the lower shell. Since the outer ring of the bearing is fixedly connected to the camera bracket lower shell, the driven rotating component is prevented from being pushed out during assembly by fixing the first connecting part to the inner ring. The driven rotating component completely replaces the function of the bearing clamp, eliminating the need for a bearing clamp in the rotating assembly, simplifying its structure, and reducing manufacturing costs.

Description

Technical Field

[0001] This utility model relates to the field of video surveillance technology, and in particular to a security camera rotating assembly and camera. Background Technology

[0002] The horizontal rotation of dome cameras or pan-tilt cameras (hereinafter referred to as cameras) is mainly achieved through direct motor drive, motor plus gear transmission, motor plus pulley transmission, and motor plus worm gear transmission. Among them, direct motor drive is generally used in very low-cost cameras, but it is more prone to shaking and unstable rotation. Worm gear transmission is generally used in large industrial pan-tilt units. Ordinary cameras mostly use gear transmission or belt transmission solutions. The two solutions are similar, and the gears can be replaced with pulleys.

[0003] Bearings are typically added to gear drives to reduce friction and vibration. Generally, the outer ring of the bearing is fixed to a stationary part of the camera, such as the bracket or upper housing. The inner ring of the bearing mates with the moving part, usually through a gear and a bearing clamp, which are secured together with screws to clamp the inner ring. The ball mount is then fixed to the bearing clamp with screws. The transmission chain is: motor → motor-mounted gear → driven gear (mates with the bearing inner ring) → bearing clamp → ball mount → ball. For example, patent CN113418117B uses a bearing clamp and the inner ring of the bearing for transmission. However, cameras using this transmission method suffer from complex structures and high manufacturing costs. Utility Model Content

[0004] This invention provides a rotating component for a security camera to solve the problems of complex structure and high manufacturing cost in the existing technology.

[0005] This utility model provides a rotating assembly for a security camera, comprising:

[0006] The lower housing of the camera bracket is equipped with mounting holes;

[0008] A spherical fixing bracket is located below the lower shell of the camera bracket;

[0009] A bearing is fitted into the mounting hole, and the outer ring of the bearing is fixedly connected to the lower shell of the camera bracket.

[0010] The driven rotating component has a first connecting part on the side near the ball fixing bracket. The first connecting part is embedded in the inner ring of the bearing and connected to the ball fixing bracket. The first connecting part is fixedly engaged with the inner ring. The driven rotating component is connected to the driving component and is used to transmit the driving force output by the driving component to the ball fixing bracket.

[0011] According to the present invention, a rotating assembly for a security camera is provided, wherein the outer peripheral surface of the first connecting part is interference-fitted with the inner ring.

[0012] According to the present invention, a security camera rotating assembly is provided, wherein a plurality of first ribs are provided at circumferential intervals on the outer peripheral surface of the first connecting part, the first ribs extend along the central axis of the bearing, and the first connecting part is interference-fitted with the inner ring through the first ribs.

[0013] According to the security camera rotating assembly provided by this utility model, a guide slope is provided at the end of the first rib near the ball fixing bracket.

[0014] According to the security camera rotating assembly provided by this utility model, the thickness of the first rib gradually increases in the direction away from the spherical fixing bracket.

[0015] According to the present invention, a security camera rotating assembly is provided, wherein a plurality of first elastic buckles are provided at circumferential intervals on the outer peripheral surface of the first connecting part, and the first elastic buckles engage with the first side of the inner ring.

[0016] According to the present invention, a security camera rotating assembly is provided with a plurality of first connecting posts at one end of the first connecting part near the ball fixing bracket, and the first connecting posts are connected to the ball fixing bracket by fasteners.

[0017] According to the present invention, a security camera rotating assembly is provided, wherein the driven rotating member has a step on the side near the ball fixing bracket, the first side of the inner ring abuts against the ball fixing bracket, and the second side of the inner ring abuts against the step.

[0018] According to the present invention, a security camera rotating assembly is provided, wherein a plurality of second connecting parts are provided circumferentially at intervals on the side of the outer ring away from the spherical fixing bracket, and the second connecting parts are detachably connected to the lower shell of the camera bracket.

[0019] This utility model also provides a camera, including a camera sphere and the security camera rotating assembly described in any of the above claims, wherein the camera sphere is connected to a sphere fixing bracket.

[0020] The security camera rotating assembly provided by this utility model effectively solves the process problems in actual assembly by fixing the outer ring of the bearing (which is a stationary component) to the lower shell of the camera bracket and fixing the first connecting part on the driven rotating component to the inner ring of the bearing. This prevents the driven rotating component from being pushed out when installing the ball fixing bracket, ensuring smooth assembly. Since the driven rotating component completely replaces the function of the bearing clamp, there is no need for a separate bearing clamp or screws for fastening the bearing clamp. Therefore, the number of parts is reduced, the overall structure is simplified, and the complexity of the structure is reduced. This not only directly eliminates the material cost of the bearing clamp and screws, but also simplifies the assembly process and shortens the assembly time, thereby significantly reducing labor and time costs and ultimately reducing the overall manufacturing cost of the product.

[0034] Figure 1 This is a front view cross-sectional structural diagram of the security camera rotating assembly provided by this utility model. Figure 2 This is an exploded structural diagram of the rotating assembly of the security camera provided by this utility model. (See attached diagram) Figure 1 and Figure 2 As shown, the security camera rotating assembly includes a camera bracket lower housing 100, a driving component 200, a ball bearing fixing bracket 300, a bearing 400, and a driven rotating component 500. The camera bracket lower housing 100 provides a mounting base for the driving component 200, the bearing 400, and the driven rotating component 500. The camera bracket lower housing 100 is provided with a mounting hole 110, which is located in the middle of the camera bracket lower housing 100. The mounting hole 110 is a circular through hole, allowing the first connecting part 510 of the driven rotating component 500 to pass through the mounting hole 110 to the bottom of the camera bracket lower housing 100. The camera bracket lower housing 100 is located below the camera bracket upper cover and is detachably connected to the camera bracket upper cover. The camera bracket lower housing 100 and the camera bracket upper cover cooperate to form a mounting cavity, providing a closed environment for the driving component 200, the bearing 400, and the driven rotating component 500.

[0035] The drive unit 200 is disposed on the upper part of the lower housing 100 of the camera bracket and located within the aforementioned mounting cavity. The drive unit 200 is used to output driving force to drive the ball-mounted bracket 300 to rotate. The ball-mounted bracket 300 is located below the lower housing 100 of the camera bracket and is used to mount the camera ball 600.

[0036] The bearing 400 is embedded in the mounting hole 110, and its outer ring is fixedly connected to the lower housing 100 of the camera bracket, thus providing a stable and reliable mounting base for the entire rotating assembly. This effectively prevents unnecessary axial rotation or vertical movement of the outer ring, which is a stationary component, ensuring the stability of the camera during rotation. Furthermore, by directly fixing the outer ring of the bearing 400 to the stationary lower housing 100 of the camera bracket, the driven rotating component 500 can be directly embedded in and fixedly fitted to the inner ring of the bearing 400, simplifying the structure of the rotating assembly and reducing manufacturing costs.

[0037] The driven rotating member 500 is annular. A first connecting portion 510 is provided on the side of the driven rotating member 500 near the ball-fixed bracket 300, specifically at the bottom of the driven rotating member 500. The first connecting portion 510 has a hollow columnar structure and is coaxially arranged with the driven rotating member 500. The outer diameter of the first connecting portion 510 is smaller than the outer diameter of the driven rotating member 500. The first connecting portion 510 is embedded in the inner ring of the bearing 400 and connected to the ball-fixed bracket 300. The first connecting portion 510 is fixedly fitted to the inner ring. The driven rotating member 500 is connected to the driving member 200 and is used to transmit the driving force output by the driving member 200 to the ball-fixed bracket 300.

[0038] The security camera rotating assembly provided by this utility model, by fixing the outer ring of the bearing (which is a stationary component) to the lower housing 100 of the camera bracket, and by fixing the first connecting part 510 on the driven rotating part 500 to the inner ring of the bearing 400, prevents the driven rotating part 500 from being pushed out when installing the ball fixing bracket 300, thus ensuring smooth assembly. Since the driven rotating part 500 completely replaces the function of the bearing clamp, there is no need for a separate bearing clamp or screws for fastening the bearing clamp. Therefore, the number of parts is reduced, the overall structure is simplified, and the complexity of the structure is lowered. This not only directly eliminates the material costs of the bearing clamp and screws, but also simplifies the assembly process and shortens assembly time, thereby significantly reducing labor and time costs, and ultimately lowering the overall manufacturing cost of the product.

[0039] In one embodiment of this utility model, see reference Figure 2 As shown, the drive unit 200 includes a drive motor 210 and a driving rotating component 220. The drive motor 210 is fixed to the lower housing 100 of the camera bracket. The driving rotating component 220 is connected to the rotating shaft of the drive motor 210 and is connected to the driven rotating component 500. The connection between the driving rotating component 220 and the driven rotating component 500 can be a direct connection, such as a meshing connection; or it can be an indirect connection, such as a belt connection.

[0040] Furthermore, in order to facilitate the fixing of the drive motor 210, the lower housing 100 of the camera bracket is provided with at least two fixing posts 120. In this embodiment, the lower housing 100 of the camera bracket is provided with two fixing posts 120, which are symmetrically arranged on both sides of the drive motor 210. The drive motor 210 is connected to the fixing posts 120 by screws.

[0041] It should be noted that in this embodiment, the driven rotating component 500 is a driven gear, and correspondingly, the driving rotating component 220 is a driving gear. The driven gear and the driving gear mesh to achieve a direct connection. Of course, the driven rotating component 500 can also be a driven pulley, and correspondingly, the driving rotating component 220 can be a driving pulley. The driven pulley and the driving pulley are indirectly connected by a belt.

[0042] In one embodiment of this utility model, see reference Figure 2 As shown, the first connecting part 510 and the driven rotating part 500 are integrally formed. This arrangement not only simplifies the overall structure of the rotating assembly and reduces the number of parts, but also lowers material and assembly costs.

[0043] In one embodiment of this utility model, the outer peripheral surface of the first connecting part 510 is interference-fitted with the inner ring of the bearing 400; of course, the connection relationship between the first connecting part 510 and the inner ring of the bearing 400 is not limited to this, and other connection relationships can also be adopted. By making the outer peripheral surface of the first connecting part 510 interference-fitted with the inner ring of the bearing 400, the inner ring of the bearing 400 is fixed in the axial and radial directions, completely replacing the bearing clamping component and screws and other components that must be set separately to achieve the same function in the prior art. Not only is the number of components reduced, but the overall structure of the rotating assembly is also simplified, reducing material costs and the complexity of the assembly process, significantly shortening the assembly time, and greatly reducing the overall manufacturing cost of the camera.

[0044] Figure 3 This is a structural schematic diagram of the driven rotating component provided by this utility model. (See attached diagram) Figure 3 As shown, in one embodiment of this utility model, a plurality of first ribs 511 are provided circumferentially at intervals on the outer peripheral surface of the first connecting portion 510. The plurality of first ribs 511 are arranged at equal intervals. Of course, in some embodiments, the distance between two adjacent first ribs 511 may not be equal. The first ribs 511 protrude relative to the outer peripheral surface of the first connecting portion 510, so that the outer peripheral surface of the first connecting portion 510 does not contact the inner ring; only the first ribs 511 contact the inner ring. The first ribs 511 are located along the central axis of the bearing 400 (i.e.,...). Figure 3Extending vertically, the first connecting portion 510 is interference-fitted with the inner ring of the bearing 400 via a first rib 511. The interference fit between the first rib 511 and the inner ring of the bearing 400 has the following main effects:

[0045] First, the first rib 511 makes line contact with the inner ring of the bearing 400, which reduces the assembly force required to achieve the interference fit. Compared with the interference fit between the entire outer circumferential surface of the first connecting part 510 and the inner ring of the bearing 400, the contact between several first ribs 511 and the inner ring of the bearing 400 significantly reduces the friction area and interference amount, making the assembly process easier and reducing the requirements for assembly tools.

[0046] Secondly, it effectively reduces processing difficulty and manufacturing costs. Machining the entire outer periphery of the first connecting part 510 to micron-level precision is extremely difficult, increasing manufacturing costs; however, machining several independent first ribs 511 to the required precision is relatively easy. The non-contact area between two adjacent first ribs 511 provides a buffer space for manufacturing tolerances, reducing the requirements for processing precision and further lowering manufacturing costs.

[0047] Furthermore, the interference fit between the first rib 511 and the inner ring of the bearing 400 ensures that the driven rotating part 500 and the inner ring of the bearing 400 rotate synchronously as a whole. This enables the power of the driving part 200 to be transmitted to the ball fixed bracket 300 accurately and without loss, avoiding delays and positioning errors caused by gaps or slippage, and ensuring the smoothness and accuracy of the camera rotation.

[0048] In one embodiment of this utility model, a guide slope 512 is provided at one end of the first rib 511 near the sphere fixing bracket 300. Specifically, see [reference needed]. Figure 3 As shown, the guide slope 512 is inclined towards the inner ring of the bearing 400. The guide slope 512 reduces the overall outer diameter of the lower end of the first connecting part 510, facilitating its insertion into the inner ring of the bearing 400. During assembly, the guide slope 512 will first contact the inner ring of the bearing 400, forming a smooth transition. This effectively reduces the overall outer diameter of the lower end of the first connecting part 510, automatically correcting slight positional deviations and guiding the lower end of the first connecting part 510 smoothly into the inner ring of the bearing 400, ensuring proper assembly of the first connecting part 510 and the inner ring of the bearing 400.

[0049] In one embodiment of this utility model, the thickness of the first rib 511 gradually increases in the direction away from the ball fixing bracket 300, that is, the thickness of the upper end of the first rib 511 is greater than the thickness of the lower end. The thinner structure at the lower end of the first rib 511, combined with the guide slope 512, allows the first connecting part 510 to easily enter the inner ring of the bearing 400, with lower requirements for assembly precision. As the pressing proceeds, the interference gradually increases, and the assembly force increases steadily, avoiding the initial alignment difficulties in traditional straight cylindrical interference fits and improving assembly efficiency. In addition, this progressive locking method ensures the reliability and stability of the connection. The reliable self-locking achieved by relying on the taper of its own structure ensures that the driving torque can be transmitted in a timely manner, ensuring the smooth rotation and precise positioning of the camera.

[0050] It should be noted that the thickness of the first rib 511 refers to the dimension of the first rib 511 in the radial direction of the first connecting part 510.

[0051] In another embodiment of this utility model, the outer diameter of the first connecting part 510 gradually increases in the direction away from the ball fixing bracket 300, that is, the outer diameter of the upper end of the first connecting part 510 is greater than the outer diameter of the lower end of the first connecting part 510. This setting can also achieve the same locking effect as the previous embodiment.

[0052] In one embodiment of this utility model, a plurality of first elastic buckles (not shown) are spaced apart circumferentially on the outer peripheral surface of the first connecting part 510. Each first elastic buckle has the same structure, and the multiple first elastic buckles are arranged at intervals circumferentially. This arrangement enables the locking force to be evenly distributed circumferentially, ensuring the stability and concentricity of the connection. Preferably, a plurality of clearance holes are provided on the outer peripheral surface of the first connecting part 510. The clearance holes can be through holes or blind holes. The first elastic buckles are correspondingly disposed in the clearance holes. In the unstressed state, the first elastic buckles protrude relative to the outer peripheral surface of the first connecting part 510. The clearance holes provide the necessary clearance space for the first elastic buckles when pressed, ensuring that the first connecting part 510 smoothly enters the predetermined position of the inner ring of the bearing 400, and preventing damage to the first elastic buckles during the pressing process.

[0053] After the first connecting part 510 enters the inner ring of the bearing 400, the first elastic buckle contacts the inner surface of the inner ring. The elastic part of the first elastic buckle is squeezed and deformed, and the first elastic buckle enters the corresponding clearance hole, so that the first connecting part 510 can smoothly enter the inner ring. After the first connecting part 510 is installed in place, the first elastic buckle engages with the first side of the inner ring of the bearing 400 to lock the driven rotating part 500 with the inner ring, preventing the driven rotating part 500 from being pushed out when installing the ball fixing bracket 300, and ensuring the smooth progress of the assembly. This assembly method achieves the locking function of traditional pressure parts and screws at a very low cost, ensuring the smooth progress of the assembly.

[0054] In one embodiment of this utility model, see reference Figure 3 As shown, the first connecting part 510 is located at one end near the ball fixing bracket 300 (i.e. Figure 3 The lower end of the first connecting part 510 is provided with a plurality of first connecting posts 513, which are arranged at intervals along the circumference. In this embodiment, three first connecting posts 513 are provided, and the distance between any two adjacent first connecting posts 513 is equal. Of course, the number of first connecting posts 513 is not limited to three, and can be determined according to actual needs. The uniformly arranged first connecting posts 513 form a stable multi-point support plane, which can effectively prevent the ball fixing bracket 300 after connection from tilting or shaking.

[0055] The lower end of the first connecting post 513 protrudes relative to the lower end face of the first connecting part 510, forming an installation reference surface. This ensures precise positioning of the sphere fixing bracket 300 during installation. The upper end of the first connecting part 510 extends upward and connects to the inner surface of the first connecting part 510. Thus, the first connecting post 513 not only serves as a connector but also as a reinforcing rib, improving the structural strength and rigidity of this thin-walled component and enhancing its resistance to torsional and bending deformation, ensuring accurate power transmission. The lower end of the first connecting post 513 is connected to the sphere fixing bracket 300 by screws, thereby achieving a reliable connection between the first connecting part 510 and the sphere fixing bracket 300. This detachable connection method also simplifies the camera assembly or maintenance process and reduces the maintenance cost throughout its entire life cycle.

[0056] In another embodiment of this utility model, the spherical fixing bracket 300 is provided with a plurality of second elastic buckles (not shown). The plurality of second elastic buckles are arranged at equal intervals along the circumference so that the locking force is evenly distributed at the connection between the first connecting part 510 and the spherical fixing bracket 300, ensuring the stability and concentricity of the connection. Correspondingly, the outer circumferential surface of the lower end of the first connecting part 510 is provided with a plurality of slots. The plurality of slots are arranged at intervals along the circumference, and the plurality of slots are engaged with the plurality of second elastic buckles one by one, thereby realizing a reliable connection between the first connecting part 510 and the spherical fixing bracket 300. The connection method of snap-fit ​​engagement simplifies the complex tightening operation into a single pressing action, which greatly shortens the assembly time, improves the assembly efficiency, reduces the number of screws, and further reduces the production cost. By eliminating screws and their corresponding tapping process, not only are material costs directly saved, but labor costs are also reduced.

[0057] In another embodiment of this utility model, see Figure 4 As shown, a step 520 is provided on the side of the driven rotating component 500 near the ball fixing bracket 300, that is, a step 520 is provided at the bottom of the driven rotating component 500. The first side of the inner ring of the bearing 400 abuts against the ball fixing bracket 300, and the second side of the inner ring abuts against the step 520. In this way, the inner ring is clamped between the ball fixing bracket 300 and the step 520. This bidirectional clamping structure firmly locks the inner ring of the bearing 400 axially, which can effectively prevent the inner ring from moving when the camera rotates or is impacted, and ensure the stability of operation.

[0058] In another embodiment of this utility model, see Figure 2 As shown, three second connecting parts 410 are circumferentially spaced on the side of the outer ring of the bearing 400 away from the ball fixing bracket 300 (i.e., the upper side of the outer ring). The distance between any two adjacent second connecting parts 410 is equal. Of course, the number of second connecting parts 410 is not limited to this; there can be two, four, or more. The second connecting parts 410 are detachably connected to the lower housing 100 of the camera bracket. Specifically, three second connecting posts are provided on the outer wall of the mounting hole 110. The positions of the three second connecting posts correspond one-to-one with the positions of the three second connecting parts 410. The second connecting parts 410 are connected to the corresponding second connecting posts by screws. The detachable connection between the second connecting parts 410 and the lower housing 100 of the camera bracket simplifies the installation and disassembly of the bearing 400, providing convenience for the mass production and subsequent maintenance of the camera.

[0059] In another embodiment of this utility model, see Figure 3As shown, the driven rotating component 500 is provided with reinforcing ribs inside. Specifically, the reinforcing ribs include a first reinforcing rib 530 and a plurality of second reinforcing ribs 540. The first reinforcing rib 530 is disposed on the inner wall of the driven rotating component 500 and extends circumferentially. The first reinforcing rib 530 enhances the radial support force of the driven rotating component 500 and effectively prevents it from deforming when it is in interference fit with the bearing 400 or when it is subjected to radial load. Furthermore, the first reinforcing rib 530 serves as the main frame and provides a stable support foundation for the subsequent connection of the second reinforcing ribs 540.

[0060] Multiple second reinforcing ribs 540 are arranged at circumferential intervals and connected to the inner wall of the driven rotating member 500 and the first reinforcing rib 530. The second reinforcing ribs 540 are perpendicular to the first reinforcing ribs 530. The circumferentially distributed second reinforcing ribs 540 are equivalent to spokes, which uniformly transmit the stress generated by the driving torque from the inner wall to the entire structure, effectively preventing the component from twisting when transmitting torque. The connection between the second reinforcing ribs 540 and the first reinforcing ribs 530 forms an efficient "T" or "I" shaped cross-sectional structure, achieving maximum bending and torsional stiffness with minimal cross-sectional area.

[0061] In one embodiment of this utility model, see reference Figure 2 As shown, the inner wall of the mounting hole 110 is provided with a plurality of second ribs 130 at intervals along the circumference. The plurality of second ribs 130 are arranged at intervals along the circumference, and the distance between two adjacent second ribs 130 is equal. The second ribs 130 extend along the central axis of the bearing 400. The outer ring of the bearing 400 is interference-fitted or clearance-fitted with the lower housing 100 of the camera bracket through the second ribs 130, which prevents the outer ring, as a stationary part, from unnecessary rotation, while reducing the installation difficulty and high-precision machining.

[0062] It should be noted that if the lower housing 100 of the camera bracket is made of plastic, the outer ring is interference-fitted with the lower housing 100 of the camera bracket; if the lower housing 100 of the camera bracket is made of metal, the outer ring is clearance-fitted with the lower housing 100 of the camera bracket.

[0063] In one embodiment of this utility model, see further reading. Figure 2As shown, the thickness of the second rib 130 gradually decreases along the direction away from the ball fixing bracket 300, that is, the thickness of the upper end of the second rib 130 is less than the thickness of the lower end. Making the upper end of the second rib 130 thinner allows the bearing 400 to easily enter the mounting hole 110, reducing the requirement for assembly precision. As the bearing 400 continues to enter, the interference fit gradually increases, and the assembly force increases steadily, avoiding the initial alignment difficulties present in traditional straight-tube interference fits and improving assembly efficiency. Furthermore, this progressive locking method ensures the reliability and stability of the connection. The reliable self-locking achieved through the taper of its own structure guarantees the stability of the bearing 400. Preferably, the end of the second rib 130 away from the ball fixing bracket 300 is also provided with a guide slope, the function of which is the same as that of the guide slope in the above embodiment.

[0064] It should be noted that the thickness of the second rib 130 refers to the dimension of the second rib 130 in the radial direction of the mounting hole 110.

[0065] When the camera is working, its built-in drive motor 210 starts and outputs driving force. This driving force is first transmitted to the active rotating component 220 connected to the drive motor 210, causing the active rotating component 220 to start rotating. Then, the rotating active rotating component 220 transmits the rotation to the driven rotating component 500 through meshing. Then, the rotating driven rotating component 500 drives the ball fixing bracket 300 to rotate through the first connecting part 510. Then, the rotating ball fixing bracket 300 drives the camera ball 600 to rotate, finally completing the camera's rotation action.
