[0051] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.​

[0052] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium.

The first feature "below", "below" and "below" the second feature can be the first feature directly below or obliquely below the second feature, or it can only mean that the first feature is lower than the second feature in horizontal height.

[0054] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0055] The conductive slip ring, also known as brush, carbon brush or current collector ring, is an electromechanical element used to transmit power and signals in unlimited continuous rotary motion. The conductive slip ring is used to realize the electrical connection between the rotating part and the stationary part, and is applied to the scene that needs long-term rotation and needs stable transmission of energy or signal. The conductive slip ring is composed of a rotating part (rotor) and a stationary part (stator), the rotor is connected to the rotating structure of the device and moves with it, while the stator is connected to the energy or signal source of the fixed structure.

[0056] The cap-shaped conductive slip ring is named because its shape is similar to a hat, and has the characteristics of compactness and integration, and is suitable for multi-functional, high-performance, high-precision and multi-element continuous rotary motion scenes. In the security cloud platform product, the cap-shaped slip ring is used to connect the rotating camera and the fixed base, to ensure the stable transmission of power and signals in complex motion.

[0057] Since the working temperature range of the cap-shaped conductive slip ring is generally defined as-20℃ to 80℃, it can operate stably in normal or high temperature environment. However, when the device is started after long-time storage in low temperature environment (such as-40℃) (for example, the device is in a stationary state after power-on), the slip ring is prone to rotation jamming or even complete jamming. The related technology provides an automatic temperature compensator arranged in the interior of the conductive slip ring to solve the above problem. However, since the temperature detection device (such as a temperature sensor) and the heating device need to be integrated in the interior of the slip ring, the overall size of the slip ring is increased, especially for the application scenarios of the cap-shaped conductive slip ring and other high-integration and compact design application scenarios, the introduction of the additional device will destroy the original structure layout, increase the axial or radial occupied space, and it is difficult to meet the needs of the volume-sensitive fields such as security gimbals and precision medical devices.

[0058] In addition, under the internal power supply mode, the balance problem between the power consumption of the temperature compensator and the power transmission efficiency of the slip ring has not been fully solved, which may aggravate the heating of the slip ring or shorten its continuous working life. Therefore, how to ensure the reliable start and operation of the slip ring in low temperature environment, and at the same time, consider the structure compactness, low power consumption and long-term stability, is still a technical problem to be solved in the current conductive slip ring technical field.

[0059] Figure 1 is a partial sectional view of a camera provided by an embodiment of the present application. Figure 2 is Figure 1 is an enlarged view of part A in

[0060] Referring to Figure 1 and Figure 2 , the present application provides a camera, which can include a gimbal, a gun machine, a ball machine or a semi-ball machine, etc. for video monitoring. The camera includes a mounting assembly 10, a camera assembly 20, a slip ring assembly 30 and a heating component 40.

[0061] The mounting assembly 10 is used to mount the camera to a predetermined position, which can be a support, a wall or a ceiling, etc. A conversion circuit board 50 is arranged in the interior of the mounting assembly 10, which is used to realize signal conversion, connection and expansion and testing functions. For example, in an electronic device, the conversion circuit board can connect chips and control circuit boards, display screens and mainboards, sensors and controllers, etc.

[0062] The power supply line and the signal line introduced from the outside of the camera enter the interior of the mounting assembly 10 through the line concentration hole of the mounting assembly 10. The power supply line and the signal line are arranged along the pre-designed wiring groove in the interior of the mounting assembly 10, the power supply line is connected with the power supply interface on the conversion circuit board 50, and the signal line is connected with the corresponding signal interface on the conversion circuit board 50.

[0063] The camera assembly 20 is rotatably arranged on the mounting assembly 10 and can rotate relative to the mounting assembly 10 to perform image acquisition. A control circuit board 60 is arranged inside the camera assembly 20 and is used to control the operation of electromechanical elements in the camera assembly 20.

[0064] Figure 3 It is a structural schematic diagram of the slip ring assembly in the camera provided by the embodiment of the present application.

[0065] Referring to Figure 3 , the slip ring assembly 30 is a cap type conductive slip ring, which looks like a hat. The cap type conductive slip ring is provided with a flange 311, and is fixedly connected to the mounting assembly 10 through the flange 311. The slip ring assembly 30 can transmit current and data signals from the adapter circuit board 50 of the mounting assembly 10 to the control circuit board 60 of the camera assembly 20.

[0066] The slip ring assembly 30 comprises a slip ring shell 31, a stator structure 32 and a rotor structure 33.

[0067] The slip ring shell 31 is in a cylindrical shape and is fixedly connected to the mounting assembly 10 through the flange 311. The stator structure 32 is fixed on the inner wall of the slip ring shell 31 by screws, and an insulating gasket is arranged between the stator structure 32 and the slip ring shell 31 to prevent short circuit between the stator structure 32 and the slip ring shell 31. The lead-out wire of the stator structure 32 is connected to the adapter circuit board 50 through a lead-out hole (not shown in the figure) on the slip ring shell 31, and the lead-out hole is sealed by a rubber sealing sleeve. The outer diameter of the rotor structure 33 is slightly smaller than the inner diameter of the stator structure 32, so that the rotor structure 33 can be sleeved inside the stator structure 32 and coupled with the stator structure 32, and can rotate flexibly relative to the stator structure 32. The lead-out wire of the rotor structure 33 is connected to the control circuit board 60 through a terminal post at the top of the slip ring assembly 30. The terminal post and the lead-out wire of the rotor structure 33 are connected by welding, and the interface between the terminal post and the top of the slip ring assembly 30 is sealed by sealing glue.

[0068] The heating component 40 is arranged on the outer surface of the slip ring shell 31 and is used to provide heat for the stator structure 32 and the rotor structure 33. The heating component 40 is arranged on the outer surface of the slip ring shell 31 and is attached to the slip ring shell 31 by heat-conducting glue or the like, so as to ensure that heat can be effectively transmitted to the stator structure 32 and the rotor structure 33 inside the slip ring shell 31, prevent the electrical performance of the stator structure 32 and the rotor structure 33 from being reduced in a low-temperature environment, and prevent the slip ring assembly 30 from being stuck or dead during startup, so as to ensure that the camera can work normally in a cold environment.

[0069] The heating component 40 can also adopt a structure of a heating film, a heating resistor or a heating wire, etc. The heating film can be wrapped on the outer surface of the slip ring shell 31. The heating resistor can be sleeved on the outer surface of the slip ring shell 31. The heating wire can be spirally wound on the outer surface of the slip ring shell 31.

[0070] It can be understood that the camera provided by the embodiment of the utility model can provide heat for the stator structure 32 and the rotor structure 33 by arranging the heating component 40 on the outer surface of the slip ring shell 31, which can ensure that the heat is transmitted to the stator structure 32 and the rotor structure 33 inside the slip ring shell 31, prevent the electrical performance of the stator structure 32 and the rotor structure 33 from being reduced in a low-temperature environment, prevent the slip ring assembly 30 from being stuck or dead, and ensure that the camera can work normally in a cold environment. Moreover, the heating component 40 is arranged on the outer surface of the slip ring shell 31, which does not occupy the space inside the slip ring shell 31, does not need to additionally add a fixing support or adjust the structural layout inside the slip ring shell 31, can significantly reduce the overall size of the slip ring assembly 30 and the heating component 40, and can be applicable to the camera and other devices with high volume requirements, and meet the design requirements of miniaturization and light weight.

[0071] Meanwhile, the heating component 40 is arranged on the outer surface of the slip ring shell 31, and the heating component 40 is independent of the structure inside the slip ring shell 31, so that the heating component 40 can be individually disassembled and replaced when a fault occurs, without the need to disassemble the whole slip ring assembly 30, and the maintenance cost can be reduced.

[0072] Figure 4 is a structural schematic view of one embodiment of the heating component in the camera provided by the embodiment of the utility model.

[0073] Referring to Figure 4 In some embodiments of the utility model, the heating component 40 comprises at least one heating piece 41 and a connecting wire 42, the at least one heating piece 41 is wrapped on the outer surface of the slip ring shell 31, one end of the connecting wire 42 is connected with the heating piece 41, and the other end of the connecting wire 42 is arranged through the flange plate 311 of the slip ring shell 31 and is electrically connected with the adapter circuit board 50.

[0074] When the heating piece 41 comprises a heating film, at least one heating film is arranged, and two, three or four heating films can also be arranged. The heating film can be in a sheet shape or a film shape, and at least one heating film can be fixed on the outer surface of the slip ring shell 31 by high-temperature-resistant glue, so as to reduce the diffusion of heat to the non-target area of the slip ring shell 31 and reduce the invalid heat loss.

[0075] Meanwhile, a small metal clamp can be used to assist in fixing the edge part of the heating film, so as to ensure that the heating film will not be displaced during the operation of the slip ring.

[0076] When the number of heating films is set to two or more, the heating films are arranged along the axial direction of the slip ring housing 31 in sequence, and the heating power of each heating film is different. The heating power of each heating film can be determined according to the overall structure of the slip ring assembly 30 and the heat demand difference at different axial positions.

[0077] Figure 5 is an example of a heating component in a camera provided by an embodiment of the present application.

[0078] Referring to Figure 5 When the number of heating films is set to three, the three heating films are arranged along the axial direction of the slip ring housing 31 in sequence, and the three heating films are heating film A 411, heating film B 412, and heating film C 413.

[0079] When two heating films, i.e. heating film A 411 and heating film B 412, are arranged along the axial direction of the slip ring housing 31 in sequence, the heating film A 411 and the heating film B 412 are set to different heating powers, and the mutual combination can realize multi-stage temperature control. For example, the power corresponding to the heating film A 411 is W1, and the maximum heating temperature can be T1. The power corresponding to the heating film B 412 is W2, and the maximum heating temperature can be T2, wherein W1 < W2, and T1 < T2.

[0080] It can be understood that each heating film has an independent power input interface. The power input interface of the heating film A 411 is connected to the power control module outside the slip ring assembly 30 through a high-temperature-resistant connecting line. The connecting line can be routed along the pre-designed wiring groove on the surface of the slip ring housing 31, and the connecting point between the connecting line and the heating film is sealed by welding and insulating glue to prevent electric leakage. Similarly, the heating film B 412 and the heating film C 413 are also connected to the power control module in a similar manner, and the respective circuits are independent of each other.

[0081] When the heating element 41 includes a heating resistor, the heating resistor is configured in a cylindrical structure, such as a copper sleeve. The heating resistor sleeve is arranged outside the slip ring housing 31.

[0082] The size of the heating resistor is determined according to the outer diameter of the slip ring housing 31 and the heating demand. Assuming that the outer diameter of the slip ring housing 31 is D. In order to ensure good heat conduction between the heating resistor and the slip ring housing 31, the inner diameter of the heating resistor should be slightly larger than the outer diameter of the slip ring housing 31, so as to leave a certain amount of space between the heating resistor and the slip ring housing 31. The wall thickness of the heating resistor is determined according to the required resistance value and power. For example, if a higher heating power is required, a thicker wall thickness can be selected to increase the cross-sectional area of the heating resistor and reduce the resistance value, thereby increasing the power. The length of the heating resistor is determined according to the axial length of the slip ring and the requirements of the heating area.

[0083] When the heating element 41 comprises a heating wire, the heating wire is wound in a spiral manner to form a cylindrical structure. During winding, the spacing of the resistance wire is uniform to ensure the uniformity of heating. For example, a special winding machine can be used to wind the nichrome resistance wire on a cylindrical mold according to a predetermined spacing, and then the cylindrical structure is formed by taking it off the mold after winding is completed and is sleeved outside the slip ring shell 31.

[0084] In some embodiments of the present application, a layer of heat-conducting silicone grease can be applied between the heating resistance and the slip ring shell 31. The heat-conducting silicone grease has good heat-conducting performance and can effectively fill the tiny gap between the heating resistance and the slip ring shell 31, thereby improving the heat conduction efficiency.

[0085] In addition, the heating film, the heating resistance and the heating wire described above can also be mixed and arranged. For example, if the length of the slip ring shell 31 is limited and the number of heating films cannot be increased, a circle of hollow columnar heating resistances can be arranged around the slip ring shell 31 for heating. The connecting lines of the heating films and the heating resistances are connected to the adapter circuit board, and the heating is controlled through the adapter circuit board.

[0086] Continuing to refer to Figure 1 and Figure 2 In some embodiments of the present application, the camera further comprises a temperature detection unit 70, which is arranged on the adapter circuit board 50 and located close to the slip ring assembly 30. The temperature detection unit 70 is used to monitor the working temperature of the environment where the slip ring assembly 30 is located.

[0087] The temperature detection unit 70 can adopt a thermistor, which has the characteristic that the resistance value increases when the temperature rises, so that automatic temperature control can be realized without the need for additional complex temperature control devices. That is, the temperature detection unit 70 can comprise a PTC thermistor connected to a control circuit, and the control circuit is located on the adapter circuit board 50. The control circuit controls the working state of the heating element 41 by monitoring the environmental temperature of the slip ring assembly 30.

[0088] When the environmental temperature of the slip ring assembly 30 is lower than a preset value, the control circuit supplies power to the heating element 41, so that the heating element 41 starts heating to provide heat for the stator structure 32 and the rotor structure 33. When the environmental temperature rises to a certain value, the control circuit cuts off the power supply of the heating element 41, so that the heating element 41 stops heating.

[0089] In the embodiments of the present application, the temperature detection unit 70 is arranged to form a feedback regulation mechanism. The controller analyzes the feedback data of the temperature detection unit 70, and controls the corresponding heating element 41 to heat according to the feedback data of the temperature detection unit 70.

[0090] The camera provided by the embodiment of the utility model is powered on during working, the thermal resistance monitors the environment temperature of the slip ring assembly 30 in real time, the adapter circuit board 50 converts the thermal resistance resistance value into the working temperature T of the environment where the slip ring assembly 30 is located through the background configuration table.

[0091] When the detected working temperature T is greater than or equal to 0 DEG C, the heating part 41 does not start heating, and the thermal resistance continues to monitor the slip ring working temperature T in real time.

[0092] When the detected working temperature T is less than or equal to 0 DEG C, the heating part 41 starts heating, and at this time, the temperature control refinement logic judgment is entered:

[0093] When -20 DEG C is less than or equal to T and T is less than or equal to 0 DEG C, the heating film A 411 is started to perform primary heating.

[0094] When -40 DEG C is less than or equal to T and T is less than or equal to -20 DEG C, the heating film B 412 is started to perform secondary heating.

[0095] When T is less than or equal to -40 DEG C, the heating film A 411 and the heating film B 412 are started to perform tertiary heating.

For example, the adapter part can be a structure with a positioning pin and a positioning hole.

[0097] The first mounting shell 12 is connected with the top cover 11 and limits a first containing cavity 14 with the top cover 11. The connection mode of the first mounting shell 12 and the top cover 11 can be various forms of combinations. At the connection part, a sealing rubber strip can be used to ensure the sealing property of the connection. The sealing rubber strip can be mounted on the connecting edge of the first mounting shell 12 or the top cover 11, and when the two are connected, the sealing rubber strip is squeezed in the middle, thereby preventing dust, moisture and the like from entering the first containing cavity 14.

[0098] The adapter circuit board 50 is arranged in the first containing cavity 14 and can be fixed on the first mounting shell 12 through screws or clips. When the adapter circuit board 50 is fixed through screws, screw holes are designed in advance on the adapter circuit board 50, and corresponding screw columns are arranged on the first mounting shell 12.
