Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera technology, and in particular to a camera housing assembly, camera device and aircraft. Background Technology
[0002] There are many types of cameras, but their basic working principle is the same: converting optical image signals into electrical signals for storage or transmission. When we photograph an object, the light reflected from the object is collected by the camera lens and focused onto the light-receiving surface of the imaging device (such as the target surface of a camera tube). The imaging device then converts the light into electrical energy, resulting in a "video signal." Typically, aircraft are equipped with cameras to film landing gear and runways, providing auxiliary video monitoring during takeoff and landing. While cameras are protected by an external casing, water can accumulate inside the casing over time, potentially affecting the camera components. Therefore, it is necessary to actively drain the water from the casing's interior regularly.
[0003] In related technologies, the process of draining water from the outer casing is quite complex. Utility Model Content
[0004] This invention aims to at least solve one of the technical problems existing in the prior art. In view of this, embodiments of this application aim to provide a camera housing assembly, a camera device, and an aircraft to simplify the drainage process of the housing.
[0005] To achieve the above objectives, one embodiment of this application provides a camera housing assembly, including:
[0006] The outer casing has a first chamber and a drain hole for communicating with the outside.
[0007] A drainage component is installed in the housing and located in the first cavity. The drainage component has an abutment portion and a connecting hole. The connecting hole communicates with the first cavity and the drainage hole respectively and is located between the first cavity and the drainage hole.
[0008] The first fastener is detachably installed on the drainage component;
[0009] A second fastener is installed on the drain component. The second fastener has a first state and a second state. When the second fastener is in the first state, the first fastener is fixed relative to the drain component. When the second fastener is in the second state, the second fastener is movable relative to the drain component. The abutment portion is used to prevent the second fastener from disengaging from the drain component.
[0010] A drain cover is provided on the drain component. The drain cover can be fixed relative to the drain component to close the connecting hole under the fastening action of the first fastener and the second fastener. When the first fastener is disengaged from the drain component and the second fastener is in the second state, the drain cover can open the connecting hole to make the drain hole communicate with the connecting hole.

[0012] In the embodiment of this application, the drain cover can be fixed relative to the drain member by a first fastener and a second fastener, thereby sealing the connecting hole. When the first fastener is disengaged from the drain member and the second fastener is in a second state, the drain cover can detach from the drain member, thereby allowing the drain hole to connect with the connecting hole, and the liquid in the first chamber can flow to the outside through the connecting hole and the drain hole in sequence. During the drainage process, the abutting part of the drain member can prevent the second fastener from disengaging from the drain member, so that the drain cover can be hung on the drain member by the second fastener, and the end of the drain cover facing the first fastener can be fully opened, so that the operator can achieve the drainage process of the outer shell without having to remove the drain cover by hand. Furthermore, during the drainage process, the liquid in the first chamber will exert a certain degree of pressure on the drain cover. When the drain cover is opened, the abutting part can limit the movement of the drain cover by the first fastener, reducing the possibility of the drain cover being blown away by the liquid, thereby reducing the occurrence of accidents.
[0013] According to some embodiments of this application, the drainage component has a first fastening groove and a first connecting groove that are interconnected. The first fastening groove is located on the side of the first connecting groove opposite to the drainage hole. The groove wall of the first fastening groove is threaded. The first fastener can be threadedly connected to the first fastening groove. The first connecting groove extends along the first fastening groove toward the drainage hole to the end face of the drainage component.
[0014] According to some embodiments of this application, the drainage component has a second fastening groove and a second connecting groove that are interconnected. The second fastening groove is located on the side of the second connecting groove away from the drainage hole. The abutment portion is located at one end of the second connecting groove away from the second fastening groove. The groove wall of the second fastening groove is threaded. When the second fastener is in the second state, the second fastener is threadedly connected to the second fastening groove.
[0015] According to some embodiments of this application, at least a portion of the outer casing has a curved surface.

Detailed Implementation
[0041] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0043] In the description of the embodiments of this application, the technical terms "first," "second," "third," etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.
[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0045] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.
[0046] In the description of the embodiments of this application, the technical terms "top", "bottom", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, operated or used in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.
[0047] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0049] In related technologies, the camera module is installed inside a housing with drainage holes, allowing liquid inside the camera housing assembly to flow to the outside. The drainage process can be actively controlled via a drainage cap; simply removing the cap allows the liquid inside the camera housing assembly to drain out. However, when a significant amount of liquid accumulates inside the camera housing, it creates considerable pressure on the drainage cap. To prevent the cap from being blown away, operators must carefully handle it to minimize the risk of it being dislodged. Furthermore, the drainage cap is typically fastened to the housing with fasteners, requiring operators to hold the cap in their hands or find suitable storage space to prevent loss, making the drainage process somewhat complex.
[0050] The drain cover 500 of this application can be pressed against the drain member 200 by the first fastener 300 and the second fastener 400 to seal the connecting hole 200b. When the first fastener 300 is disengaged from the drain member 200 and the second fastener 400 switches from the first state to the second state, the drain cover 500 can open the connecting hole 200b to allow liquid in the first chamber 100a to flow to the outside through the connecting hole 200b. The abutment portion 200a can prevent the second fastener 400 from disengaging from the drain member 200, thereby allowing the drain cover 500 to be hung on the drain member 200.
[0051] This application proposes to provide an aircraft, including a fuselage and a camera device, wherein the camera device is mounted on the fuselage.
[0052] For example, the aircraft is an airplane.
[0053] For example, the aircraft also includes landing gear mounted on the fuselage, which is movable relative to the fuselage. A camera device is mounted on the bottom of the fuselage to capture images of the landing gear.
[0054] This application intends to provide a camera device; please refer to [link / reference]. Figure 6 and Figure 7The camera device includes a camera housing 100 assembly, a camera module 900, a main control board 910, a first connector 920, a power board 930, and a second connector 940. The camera module 900 is mounted within the camera housing 100 assembly. The main control board 910 is electrically connected to the camera module 900. The first connector 920 is electrically connected to the main control board 910 and is used for electrical connection to a sealed socket. The power board 930 is electrically connected to the main control board 910. The second connector 940 is electrically connected to the power board 930 and is used for electrical connection to the sealed socket.
[0055] For example, the first connector 920 and the second connector 940 are micro rectangular connectors.
[0056] For example, the main control board 910 and the power supply board 930 are arranged at intervals in the vertical direction.
[0057] For example, the up and down direction is as follows Figure 2 The direction indicated by the middle arrow R1.
[0058] In the embodiment of this application, the camera device is provided with a first connector 920 and a second connector 940 which are electrically connected to the main control board 910 and the power board 930, respectively. The wires on the main control board 910 are used to transmit image signals. The power and image signals are routed through the corresponding connectors, which can improve electromagnetic compatibility reliability and reduce the degree of mutual interference between electromagnetic signals, thereby making the camera module 900 more stable during operation.
[0059] This application intends to provide a camera housing 100 assembly; please refer to [link / reference]. Figures 1 to 3The camera housing 100 assembly includes a housing 100, a drain component 200, a first fastener 300, a second fastener 400, and a drain cover 500. The housing 100 has a first chamber 100a and a drain hole 100b, the drain hole 100b being for communication with the outside. The drain component 200 is mounted on the housing 100 and located within the first chamber 100a. The drain component 200 has an abutment portion 200a and a connecting hole 200b, the connecting hole 200b communicating with both the first chamber 100a and the drain hole 100b, and is located between the first chamber 100a and the drain hole 100b. The first fastener 300 is detachably mounted on the drain component 200, and the second fastener 400 is mounted on the drain component 200. The second fastener 400 has a first state and a second state. When the second fastener 400 is in the first state, the first fastener 300 is fixed relative to the drain member 200. When the second fastener 400 is in the second state, the second fastener 400 can move relative to the drain member 200. The abutment portion 200a is used to prevent the second fastener 400 from separating from the drain member 200. The drain cover 500 is placed on the drain member 200. The drain cover 500 can be fixed relative to the drain member 200 to close the connecting hole 200b under the fastening action of the first fastener 300 and the second fastener 400. When the first fastener 300 is separated from the drain member 200 and the second fastener 400 is in the second state, the drain cover 500 can open the connecting hole 200b to allow the drain hole 100b to communicate with the connecting hole 200b.
[0060] For example, please refer to Figure 3 The drain cover 500 has a first clamping part 500a and a second clamping part 500b. A first fastener 300 and a second fastener 400 pass through the first clamping part 500a and the second clamping part 500b, respectively. When the first fastener 300 is installed on the drain component 200, the first clamping part 500a is clamped by the first fastener 300 and the drain component 200. When the second fastener 400 is in the first state, the second clamping part 500b is clamped by the second fastener 400 and the drain component 200. The first clamping part 500a can prevent the first fastener 300 from disengaging from the drain cover 500. When the first fastener 300 is disengaged from the drain component 200 and the second fastener 400 is in the second state, the first fastener 300 can be hung on the drain cover 500, thereby avoiding the need for the operator to hold the first fastener 300 to prevent it from being lost.
[0061] For example, the outer casing 100 is detachably connected to the body, and the drain component 200 is detachably connected to the outer casing 100. When the outer casing 100 is detached from the body, the first chamber 100a is visible to the outside, thereby enabling the drain component 200 located in the first chamber 100a to be repaired or replaced.
[0062] For example, the drain component 200 is made of stainless steel, the drain component 200 has a high degree of ease of use, and can provide greater connection strength for the first fastener 300 and the second fastener 400.
[0063] For example, the camera device also includes a camera cable 950, which is installed in the first chamber 100a.
[0064] In this embodiment, the drain cover 500 is fixed relative to the drain member 200 by the first fastener 300 and the second fastener 400, thereby sealing the connecting hole 200b. When the first fastener 300 is disengaged from the drain member 200 and the second fastener 400 is in a second state, the drain cover 500 can disengage from the drain member 200, thereby allowing the drain hole 100b to connect with the connecting hole 200b, and the liquid in the first chamber 100a can flow to the outside through the connecting hole 200b and the drain hole 100b in sequence. During the drainage process, the abutting portion 200a of the drain member 200 can prevent the second fastener 400 from disengaging from the drain member 200, so that the drain cover 500 can be hung on the drain member 200 by the second fastener 400, and the end of the drain cover 500 facing the first fastener 300 can be fully opened, so that the operator can achieve the drainage process of the outer casing 100 without having to manually remove the drain cover 500. Furthermore, during the drainage process, the liquid in the first chamber 100a will exert a certain pressure on the drain cover 500. When the drain cover 500 is opened, the abutment can limit the movement of the drain cover 500 through the first fastener 300, reducing the possibility of the drain cover 500 being blown away by the liquid, thereby reducing the occurrence of accidents.
[0065] In one embodiment, please refer to Figure 3 The camera housing 100 assembly also includes a sealing ring 960, which is circumferentially disposed around the connecting hole 200b. The sealing ring 960 is located between the drain member 200 and the drain cover 500. The sealing ring 960 can reduce the leakage of liquid inside the first chamber 100a from the gap between the drain member 200 and the drain cover 500, thereby reducing liquid leakage from the camera housing 100 assembly in cases where drainage is not suitable.
[0066] In one embodiment, please refer to Figures 3 to 5The drain component 200 has a first fastening groove 200c and a first connecting groove 200d that are interconnected. The first fastening groove 200c is located on the side of the first connecting groove 200d opposite to the drain hole 100b, and the groove wall of the first fastening groove 200c is threaded. The first fastener 300 is a screw that can be threadedly connected to the first fastening groove 200c. The first connecting groove 200d extends along the first fastening groove 200c toward the drain hole 100b to the end face of the drain component 200. The drain component 200 and the first fastener 300 bracket are threadedly connected. The installation process of the first fastener 300 and the drain component 200 is relatively simple, and the connection strength between the first fastener 300 and the drain component 200 is high, which can reduce the possibility of the drain cover 500 being blown open by the liquid in the first chamber 100a, and the drainage process is relatively controllable.
[0067] For example, when projected along the arrangement direction of the first fastening groove 200c and the first connecting groove 200d, the projection area of the first fastening groove 200c is located within the projection area of the first connecting groove 200d.
[0068] For example, please refer to Figure 3 and Figure 5 The first fastener 300 includes a first clamping portion 300a, a first connecting portion 300b, and a first threaded portion 300c that are interconnected. The first threaded portion 300c has a thread that allows it to be threadedly connected to the first fastening groove 200c. Along the length of the first fastener 300, the first clamping portion 300a, the first connecting portion 300b, and the first threaded portion 300c are arranged sequentially. Projected along the length of the first fastener 300, the projection area of the first connecting portion 300b is located within the projection areas of the first clamping portion 300a and the first threaded portion 300c. The first connecting portion 300b has a small radial dimension, which allows the first fastener 300 to move relatively smoothly relative to the drain member 200 when the first fastener 300 is disengaged from the drain member 200, thereby reducing interference between the first fastener 300 and the drain member 200. When the first fastener 300 and the drain component 200 are fixed together, the first clamping part 300a and the drain component 200 together clamp the first pressing part 500a. When the first fastener 300 and the drain component 200 are disengaged, the first pressing part 500a can prevent the first threaded part 300c from moving from the first connecting groove 200d in a direction away from the first fastening groove 200c.
[0069] For example, the first clamping part 500a also has threads, and the first threaded part 300c can pass through the threads of the first clamping part 500a to enter the first communicating groove 200d. The first fastener 300 can also be detachably connected to the drain cover 500 through the threads of the first clamping part 500a, thereby enabling the replacement of the first fastener 300.
[0070] It is understood that other embodiments of this application do not limit the connection method between the first fastener 300 and the drain component 200. Exemplarily, the first fastener 300 can be magnetically connected to the drain component 200, and the first fastener 300 can overcome the magnetic attraction under the action of an external force to disengage the first fastener 300 from the drain component 200.
[0071] In one embodiment, please refer to Figure 3 and Figure 5 The drain component 200 has a second fastening groove 200e and a second connecting groove 200f that are interconnected. The second fastening groove 200e is located on the side of the second connecting groove 200f opposite to the drain hole 100b, and the abutment portion 200a is located at the end of the second connecting groove 200f opposite to the second fastening groove 200e. The groove wall of the second fastening groove 200e is threaded. The second fastener 400 is a screw. When the second fastener 400 is in the second state, the second fastener 400 is threadedly connected to the second fastening groove 200e. The connection between the second fastener 400 and the second fastening groove 200e is simple, and the connection strength between the second fastener 400 and the drain component 200 is high, which can further reduce the possibility of the drain cover 500 being blown open by the liquid in the first chamber 100a.
[0072] For example, please refer to Figure 3 Projecting along the arrangement direction of the second fastening groove 200e and the second connecting groove 200f, the projection area of the second fastening groove 200e is located within the projection area of the second connecting groove 200f. Along the direction from the second fastening groove 200e to the second connecting groove 200f, the second fastening groove 200e, the second connecting groove 200f, the abutment part 200a, and the drain cover 500 are arranged sequentially.
[0073] For example, please refer to Figure 3The second fastener 400 includes a second clamping portion 400a, a second connecting portion 400b, and a second threaded portion 400c connected to each other. The second threaded portion 400c has threads that can be threadedly connected to the second fastening groove 200e. Along the length direction of the second fastener 400, the second clamping portion 400a, the second connecting portion 400b, and the second threaded portion 400c are arranged sequentially. Projected along the length direction of the second fastener 400, the projection area of the second connecting portion 400b is located within the projection area of the second clamping portion 400a and the second threaded portion 400c. The radial dimension of the second connecting portion 400b is small, allowing the second fastener 400 to move relatively smoothly relative to the drain member 200 when the second fastener 400 is disengaged from the drain member 200, thereby reducing interference between the second fastener 400 and the drain member 200. When the second fastener 400 is fixed to the drain member 200, the second clamping part 400a and the abutting part 200a together clamp the second pressing part 500b. When the second fastener 400 is in the second state, the abutting part 200a can prevent the second threaded part 400c from moving from the second communicating groove 200f in a direction away from the second fastening groove 200e.
[0074] For example, both the second clamping part 500b and the abutting part 200a are threaded, and the second threaded part 400c can enter the second communicating groove 200f by means of the threads of the second clamping part 500b and the abutting part 200a. The second fastener 400 can also be connected and disconnected from the drain cover 500 by means of threads, thereby enabling the replacement of the second fastener 400.
[0075] In one embodiment, please refer to Figure 1 At least a portion of the outer shell 100 has a curved surface.
[0076] For example, the bottom surface of the housing 100 has a streamlined shape.
[0077] For example, along the top-down direction, the horizontal distance between the sidewall of the housing 100 and the central axis of the housing 100 gradually decreases.
[0078] In the embodiments of this application, at least a portion of the outer shell 100 has an arc surface. During the flight of the aircraft, the outer shell 100 will be subject to a certain degree of wind resistance, which will be transmitted to the fuselage. The arc surface can reduce the wind resistance experienced by the outer shell 100 and reduce the fuel consumption of the aircraft.
[0079] It is understood that other embodiments of this application do not limit the shape of the housing 100. Exemplarily, the shape of the housing 100 may be a cube.
[0080] In one embodiment, please refer to Figure 6 and Figure 7 The camera housing 100 assembly also includes an isolator 600 connected to the housing 100. The isolator 600 and the housing 100 enclose a second chamber 600a, which is isolated from the first chamber 100a. The second chamber 600a is used to mount the camera module 900. The isolator 600 provides mounting space for the camera module 900 in the camera device and reduces the impact of liquid in the first chamber 100a on the camera module 900, making the camera module 900 more stable during operation.
[0081] For example, the camera module 900, the main control board 910, the first connector 920, the power board 930 and the second connector 940 are all located in the second chamber 600a.
[0082] For example, the isolator 600 is detachably connected to the housing 100.
[0083] In one embodiment, please refer to Figure 7 The housing 100 also has a camera hole 100c, which is used by the camera module 900 to take pictures of the outside world. The camera housing 100 assembly also includes a light-transmitting element 700 installed on the housing 100. The light-transmitting element 700 covers the camera hole 100c, and the side of the light-transmitting element 700 facing the outside world is curved.
[0084] For example, the material of the light-transmitting element 700 is glass.
[0085] In the embodiment of this application, the side of the light-transmitting element 700 facing the outside is curved. During the flight of the aircraft, the curved light-transmitting element 700 can further reduce the wind resistance encountered by the light-transmitting element 700. Furthermore, the curved light-transmitting element 700 can be well adapted to the curved shape of the outer shell 100, and the overall shape of the camera shell 100 assembly is relatively smooth.
[0086] In one embodiment, please refer to Figure 7 The camera housing 100 assembly also includes a heating element 710, which is installed inside the housing 100 and is used to heat the light-transmitting element 700.
[0087] For example, the heating element 710 is an indium tin oxide film, and the heating element 710 is attached to the side of the light-transmitting element 700 facing the second chamber 600a. The heating element 710 is connected to a wire for electrical connection to a power source.
[0088] In the embodiment of this application, the camera housing 100 assembly is further provided with a heating element 710 to heat the light-transmitting element 700. During the shooting process of the camera module 900, the heating element 710 can reduce the occurrence of water mist or ice on the surface of the light-transmitting element 700, resulting in better imaging quality of the camera module 900.
[0089] It is understood that other embodiments of this application do not limit whether the camera housing 100 assembly is provided with a heating element 710.
[0090] For example, the heating element 710 is used to keep the light-transmitting element 700 above 20°C.
[0091] For example, the light-transmitting element 700 is bonded to the housing 100 using aviation sealant HM304.
[0092] In one embodiment, please refer to Figure 3 The drain hole 100b is located at the bottom of the housing 100.
[0093] In the embodiment of this application, the drain hole 100b is located at the bottom of the housing 100. The liquid inside the first chamber 100a can be drained as cleanly as possible through the drain hole 100b, thereby reducing the situation where a lot of liquid remains inside the first chamber 100a and affects the operation of the camera module 900.
[0094] It is understood that other embodiments of this application do not limit the location of the drain hole 100b. Exemplarily, the drain hole 100b is located on the side of the housing 100.
[0095] In one embodiment, please refer to Figure 3 The length directions of the first fastener 300 and the second fastener 400 are parallel to the vertical direction. The arrangement directions of the first fastening groove 200c and the first connecting groove 200d, the length directions of the first fastener 300, the first connecting groove 200d, the first fastening groove 200c, the arrangement directions of the second fastening groove 200e and the second connecting groove 200f, the length directions of the second fastener 400, and the length directions of the second fastening groove 200e are all parallel to the vertical direction. The liquid in the first chamber 100a can flow relatively smoothly from the first chamber 100a to the connecting hole 200b under its own gravity, thus draining to the outside, resulting in high drainage efficiency.
[0096] In one embodiment, please refer to Figure 1 The camera housing 100 assembly also includes a flange 800, which is connected to the top surface of the housing 100 and surrounds the circumference of the housing 100.
[0097] For example, the housing 100 and the flange 800 are integrally formed structures.
[0098] For example, flange 800 is bolted to the fuselage.
[0099] In the embodiment of this application, the outer shell 100 can be installed on the fuselage of the aircraft via the flange 800. The flange 800 surrounds the circumference of the outer shell 100. During the operation of the aircraft, the flange 800 can fit well against the fuselage, which can reduce the gap between the fuselage and the camera outer shell 100 assembly. The sealing between the camera outer shell 100 assembly and the fuselage is good, thereby reducing the possibility of external liquids entering the first chamber 100a through the gap between the camera outer shell 100 assembly and the fuselage.
