Description

Technical Field

[0001] This application relates to the field of surveillance camera technology, and in particular to a camera that can rotate 360 ​​degrees infinitely. Background Technology

[0002] With the development of technologies in fields such as security monitoring and intelligent robots, 360-degree unrestricted continuous rotation camera technology has become a user demand.

[0003] In related technologies, traditional flexible cables are commonly used to directly connect the rotating upper gimbal body to the fixed lower gimbal base. However, the aforementioned method and related devices using traditional flexible cables have the following problems: multiple rotations cause cable tangling (twisted wires), leading to risks of jamming, open circuits, and signal interruption, and making true 360-degree stepless rotation impossible. The stress and wear caused by the twisted wires can easily lead to malfunctions, reducing the overall reliability and lifespan of the product. In summary, existing cameras suffer from cable tangling during rotation, resulting in camera signal interruption and other problems. Utility Model Content

[0004] Based on this, this application proposes several embodiments of a camera that can rotate 360 ​​degrees infinitely, wherein at least one embodiment can solve the technical problem of cable entanglement when the camera rotates.

[0005] A camera capable of 360-degree stepless rotation includes:

[0006] Base;

[0007] The transmission assembly includes a first transmission component and a second transmission component that mesh with each other, with the bottom of the first transmission component fixed to the base.

[0008] The bottom buckle is sleeved on the first transmission component and has a gap between it and the first transmission component;

[0009] The driving component is mounted on the bottom buckle and connected to the second transmission component;

[0010] A slip ring assembly includes a stator and a rotor, the stator being fixedly connected to a base; the rotor is provided with a metal ring track for connecting to a cable, and a brush is provided between the stator and the rotor, the brush abutting against the metal ring track.

[0011] In one embodiment, the center of the base protrudes outward to form a through groove; the top end of the stator passes through the through groove, and the bottom end of the stator is connected to the base;

[0012] The slip ring assembly also includes an inner housing, the rotor is disposed inside the stator, and the brushes are disposed between the stator and the inner housing.

[0013] In one embodiment, the rotor is disposed in an inner housing; the inner housing has a groove, through which a positive or negative brush passes and abuts against a metal ring on the rotor.

[0014] In one embodiment, the metal ring is coaxially arranged with the rotor; one end of the metal ring is embedded in the rotor and connected to a cable, and the other end is arranged around the outer periphery of the rotor.

[0015] In one embodiment, the slip ring assembly has two metal ring channels spaced apart, one of which surrounds the middle of the rotor and the other surrounds the bottom of the rotor.

[0016] In one embodiment, the metal annular channel is an annular groove, and the metal annular channel is made of copper or aluminum.

[0017] In one embodiment, the slip ring assembly further includes a ball bearing and a bushing, the ball bearing being disposed between the inner housing and the rotor, and sleeved on the outer periphery of the rotor;

[0018] The bushing is located at the end of the rotor, and the cable passes through the bushing and connects to the metal ring.

[0019] In one embodiment, the outer periphery of the through groove is provided with an annular groove, and the bottom buckle is rotatably disposed within the annular groove;

[0020] The bottom buckle has a bowl-shaped structure, with a sloping surface on one side of the bottom of the bottom buckle, and one side of the annular groove is inclined relative to the bottom surface of the annular groove.

[0021] In one embodiment, both the first transmission component and the second transmission component are gears, the first transmission component has an axial through hole at its center, and the rotor passes through the through hole; a rolling bearing is provided between the bottom buckle and the first transmission component.

[0022] In one embodiment, the device further includes an upper housing, a camera body, and a control assembly, wherein the upper housing is mounted on the bottom buckle, and the camera body and the control assembly are mounted inside the upper housing.

[0023] The aforementioned 360-degree infinitely rotating camera uses a drive component to rotate a second transmission component. Since the first transmission component is fixed to the base, the second transmission component rotates relative to it. Simultaneously, the drive component is mounted on a bottom buckle, causing the bottom buckle to rotate synchronously with the second transmission component, thus achieving overall camera angle adjustment. The rotor of the slip ring assembly is rotatably mounted within the stator. Cables connect to the rotor, and brushes abut against the metal ring track. When the camera rotates, the cables rotate synchronously with the rotor, preventing entanglement and jamming. This ensures stable and continuous transmission of power and signals through the brushes and metal ring track, improving equipment reliability. Attached Figure Description

[0038] In related technologies, power and signals are transmitted through traditional connecting cables. However, when the camera rotates, the cables are prone to twisting, which may cause the cables to jam or break, affecting the reliability and lifespan of the camera rotation.

[0039] See Figure 1 , Figure 3 , Figure 4 As shown, Figure 1 A schematic diagram of the camera structure in one embodiment of this application is shown. Figure 3 A schematic diagram of the transmission assembly and slip ring assembly 50 in one embodiment of this application is shown. Figure 4 A cross-sectional schematic diagram of the transmission assembly and slip ring assembly 50 in one embodiment of this application is shown.

[0040] To solve the above-mentioned technical problems, one embodiment of this application provides a camera that can rotate 360 ​​degrees infinitely, including a base 10, a transmission component, a bottom buckle 30, a drive component 40, and a slip ring component 50, which realizes all-round, blind-angle-free monitoring, while avoiding the cable 61 from getting tangled during rotation, ensuring the continuous rotation of the camera and improving the usage effect.

[0041] In this embodiment, the transmission assembly includes a first transmission member 21 and a second transmission member 22 that mesh with each other. The bottom of the first transmission member 21 is fixed to the base 10. A bottom buckle 30 is sleeved on the first transmission member 21, with a gap between them. A drive member 40 is mounted on the bottom buckle 30 and connected to the second transmission member 22. The slip ring assembly 50 includes a stator 51 and a rotor 52. The stator 51 is fixedly connected to the base 10. The rotor 52 is provided with a metal ring channel 53 connected to a cable 61. A brush 62 is provided between the stator 51 and the rotor 52, and the brush 62 abuts against the metal ring channel 53.

[0042] The base 10 is made of plastic and has a circular structure. The center of the base 10 protrudes outward for mounting the transmission components.

[0043] The transmission assembly includes a first transmission component 21 and a second transmission component 22. The first transmission component 21 is a spur gear. The first transmission component 21 is fixed to the protruding part of the base 10. The second transmission component 22 is also a spur gear, but its diameter is smaller than that of the first transmission component 21. The second transmission component 22 meshes with the first transmission component 21 and is driven to rotate by the driving component 40.

[0044] The bottom buckle 30 is made of plastic, such as polycarbonate (PC). The bottom buckle 30 is designed as a bowl-shaped structure with a circular bottom. A through hole is provided in the middle of the bottom buckle 30. The bottom buckle 30 is fitted onto the outside of the first transmission member 21, with a gap between it and the first transmission member 21 to prevent interference with the rotation of the first transmission member 21.

[0045] The drive component 40 is a stepper motor. The drive component 40 is connected to the second transmission component 22 via a flexible coupling, causing the second transmission component 22 to rotate. Since the drive component 40 is mounted on the bottom buckle 30 and the first transmission component 21 is fixed, the second transmission component 22 rotates relative to the first transmission component 21, causing the bottom buckle 30 to rotate synchronously. The upper housing 70 of the camera is mounted on the bottom buckle 30, and the camera body 71 and control components 72 are installed inside the upper housing 70, thereby enabling the camera to rotate 360 ​​degrees and achieve all-around, blind-spot-free monitoring.

[0046] The stator 51 of the slip ring assembly 50 is made of engineering plastic. The stator 51 is fixedly connected to the interior of the base 10 by bolts. The rotor 52 of the slip ring assembly 50 is a rotating shaft 521, i.e., a bearing. The rotor 52 is rotatably mounted inside the stator 51, and can rotate simultaneously when the upper housing 70 and the bottom buckle 30 rotate with the second transmission member 22.

[0047] The rotor 52 is provided with a metal ring track 53 that connects to the cable 61. The metal ring track 53 is made of copper and its surface can be silver-plated to improve conductivity and wear resistance. The brush 62 is a silver-graphite brush, which is located between the stator 51 and the rotor 52 and abuts against the metal ring track 53 to achieve stable transmission of electrical energy and signals when the rotor 52 rotates.

[0048] In the specific implementation process, when the camera needs to be rotated to adjust the angle, the drive component 40 drives the second transmission component 22 to rotate. Since the first transmission component 21, which meshes with it, is fixed on the base 10, the second transmission component 22 can only rotate relative to the first transmission component 21. Because the drive component 40 is mounted on the bottom buckle 30, the bottom buckle 30 rotates with the second transmission component 22, achieving stepless rotation of the camera. Simultaneously, the rotor 52 is rotatably mounted inside the stator 51. The cable 61 is connected to the rotor 52, and the brush 62 abuts against the metal ring track 53 of the rotor 52. When the cable 61 rotates with the camera as a whole, the connection between the cable 61 and the rotor 52 rotates synchronously, preventing the cable 61 from tangling and jamming, and preventing interference to the cable 61 during camera rotation, ensuring optimal performance. Because the brush 62 and the metal ring track 53 always maintain contact, stable power and signal transmission is ensured, improving the overall performance.

[0049] The aforementioned camera, capable of 360-degree stepless rotation, drives the second transmission component 22 to rotate via the drive component 40. Since the first transmission component 21 is fixed to the base 10, the second transmission component 22 rotates relative to it. Simultaneously, the drive component 40 is mounted on the bottom buckle 30, causing the bottom buckle 30 to rotate synchronously with the second transmission component 22, thus achieving overall camera angle adjustment. The rotor 52 of the slip ring assembly 50 is rotatably mounted within the stator 51. The cable 61 connects to the rotor 52, and the brush 62 abuts against the metal ring track 53. When the camera rotates, the cable 61 rotates synchronously with the rotor 52, preventing entanglement and jamming. This ensures stable and continuous transmission of power and signals through the brush 62 and the metal ring track 53, improving equipment reliability.

[0050] Combination Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the base 10 provided in one embodiment of this application.

[0051] In some embodiments, the base 10 has a through groove 11 formed by the outward protrusion of its center; the top end of the stator 51 passes through the through groove 11, and the bottom end of the stator 51 is connected to the base 10. The slip ring assembly 50 also includes an inner housing 54, a rotor 52 disposed inside the stator 51, and a brush 62 disposed between the stator 51 and the inner housing 54.

[0052] Specifically, the center of the base 10 protrudes outward to form a through groove 11, so that the top of the slip ring assembly 50 can be inserted and extended.

[0053] The slip ring assembly 50 also includes a housing 511, which serves as the stator 51. Both the housing 511 and the inner housing 54 are made of engineering plastic. The top end of the housing 511 passes through the through groove 11, and the bottom end of the housing 511 is connected to the base 10 by bolts. The inner housing 54 is disposed inside the housing 511, with a gap between them. The positive brush 621 and the negative brush 622 are respectively disposed in the gap between the housing 511 and the inner housing 54.

[0054] Combination Figure 6 , Figure 7 As shown, Figure 6 This is a schematic diagram of the structure of the first transmission member 21 provided in one embodiment of this application. Figure 7 This is a cross-sectional schematic diagram of the slip ring assembly 50 provided in one embodiment of this application.

[0055] In some embodiments, the rotor 52 is disposed in the inner housing 54; a groove 541 is provided on the inner housing 54, and the positive brush 621 or the negative brush 622 passes through the groove 541 and abuts against the metal annular channel 53 on the rotor 52.

[0056] Specifically, the slip ring assembly 50 also includes a rotating shaft 521, which serves as the rotor 52 and can be made of stainless steel. The rotating shaft 521 is housed in the inner housing 54 and connected to the inner housing 54 via ball bearings 55, enabling flexible rotation.

[0057] A groove 541 is provided on the inner housing 54, through which the positive brush 621 and the negative brush 622 pass and abut against the metal ring 53. The shape and size of the groove 541 can be adjusted according to specific usage requirements, and will not be described in detail here.

[0058] In one embodiment, the metal ring 53 is coaxially arranged with the rotor 52; one end of the metal ring 53 is embedded in the rotor 52 and connected to the cable 61, and the other end is arranged around the outer periphery of the rotor 52.

[0059] Specifically, the rotating shaft 521 serves as the rotor 52, and the metal ring 53 is embedded within the rotating shaft 521, arranged coaxially with it, meaning the metal ring 53 extends along the length of the rotating shaft 521. One end of the metal ring 53 is connected to a cable 61 inside the rotating shaft 521, and the cable 61 is made of multi-strand copper wire. The other end of the metal ring 53 extends out of the rotating shaft 521 and surrounds its outer circumference to ensure good contact with the brush 62.

[0060] The area of ​​the metal ring track 53 on the outer periphery of the rotating shaft 521 is larger than the contact area between the brush 62 and the metal ring track 53, so as to ensure that the brush 62 can always contact the metal ring track 53 when the rotating shaft 521 rotates with the cable 61, thus ensuring the stable transmission of electrical energy and signals.

[0061] In one embodiment, the slip ring assembly 50 has two spaced-apart metal annular channels 53, one of which surrounds the middle of the rotor 52; the other surrounds the bottom of the rotor 52. The metal annular channels 53 are annular grooves 12 and are made of copper or aluminum.

[0062] Specifically, two metal annular channels 53 are spaced apart within the slip ring assembly 50. Each metal annular channel 53 is an annular groove 12, surrounding the center of the rotor 52, i.e., the rotating shaft 521. They are made of pure copper or pure aluminum and silver-plated to improve conductivity and wear resistance. The metal annular channel 53 is 3mm wide and 2.5mm deep. One metal annular channel 53 is connected to the positive electrode cable 611, and the other is connected to the negative electrode cable 612.

[0063] The brush 62 is elastic, which allows it to deform to a certain extent. This elastic force and deformation effect maintain close contact between the brush 62 and the metal ring channel 53.

[0064] The material, shape, and size of the metal ring 53 can be adapted to specific usage parameters, and will not be elaborated here.

[0065] In one embodiment, the slip ring assembly 50 further includes a ball bearing 55 and a bushing 56. The ball bearing 55 is disposed between the inner housing 54 and the rotor 52 and is sleeved on the outer periphery of the rotor 52. The bushing 56 is disposed at the top of the rotor 52, and the cable 61 passes through the bushing 56 and connects to the metal ring track 53.

[0066] Specifically, the ball bearing 55 is a deep groove ball bearing, and its inner diameter matches the diameter of the rotating shaft 521. The ball bearing 55 is placed between the inner housing 54 and the rotor 52, i.e. the rotating shaft 521, and is sleeved on the outer circumference of the rotating shaft 521 to ensure that the rotating shaft 521 rotates flexibly.

[0067] The bushing 56 is made of polytetrafluoroethylene. The bushing 56 is located at the top of the rotating shaft 521. The cable 61 passes through the bushing 56 and connects to the metal ring 53. The bushing 56 improves the wear resistance.

[0068] In one embodiment, an annular groove 12 is provided on the outer periphery of the through groove 11, and the bottom buckle 30 is rotatably disposed in the annular groove 12; the bottom buckle 30 has a bowl-shaped structure, and one side of the bottom of the bottom buckle 30 has a slope 31, and one side of the annular groove 12 is inclined relative to the bottom surface of the annular groove 12.

[0069] Specifically, an annular groove 12 is provided on the outer periphery of the through groove 11 of the base 10. One side of the annular groove 12 is inclined relative to the bottom surface of the annular groove 12 to adapt to the structure of the bottom buckle 30.

[0070] The bottom buckle 30 has a bowl-shaped structure, and its bottom is rotatably mounted in the annular groove 12 of the base 10. One side of the bottom of the bottom buckle 30 has an inclined surface 31, the angle of which is consistent with the inclination angle of the annular groove 12, ensuring that the bottom buckle 30 can rotate smoothly. At the same time, the rotational engagement between the inclined surfaces 31 can also limit the rotation process of the bottom buckle 30, preventing it from shifting and ensuring its rotational stability.

[0071] Combination Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the first transmission member 21 provided in one embodiment of this application. In some embodiments, the first transmission member 21 and the second transmission member 22 are both gears. The first transmission member 21 has an axial through hole 211 at its center, and the rotor 52 passes through the through hole 211. A rolling bearing 23 is provided between the bottom buckle 30 and the first transmission member 21.

[0072] Specifically, the first transmission component 21 is a spur gear. The center of the first transmission component 21 protrudes outward to form an axial through hole 211, through which the rotating shaft 521 passes. The second transmission component 22 is also a spur gear, and is located on one side of the first transmission component 21, mounted on an aluminum alloy bracket connected to the bottom buckle 30.

[0073] The rolling bearing 23 is an angular contact ball bearing. The inner diameter of the rolling bearing 23 matches the shaft diameter of the connection between the first transmission member 21 and the bottom buckle 30. It is positioned between the bottom buckle 30 and the first transmission member 21 to reduce rotational friction.

[0074] Combination Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the camera body 71 provided in one embodiment of this application. In some embodiments, it also includes an upper housing 70, a camera body 71, and a control component 72. The upper housing 70 is mounted on the bottom buckle 30, and the camera body 71 and the control component 72 are mounted inside the upper housing 70.

[0075] Specifically, the upper housing 70 is made of engineering plastic, such as polycarbonate. The upper housing 70 is fixedly installed on the bottom buckle 30 by a snap-fit ​​structure or bolts, ensuring a tight connection between the upper housing 70 and the bottom buckle 30.

[0076] The camera body 71 includes a CMOS sensor camera with functions such as autofocus and auto exposure. The camera body 71 is fixed inside the upper housing 70 by screws.

[0077] The control component 72 includes a main control chip, a storage module, and a communication module. The control component 72 is mounted inside the upper housing 70 via a circuit board, which employs a multi-layer design for excellent anti-interference capabilities.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
