Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and particularly to a camera housing assembly, a camera device, and an aircraft. Background Art

[0002] There are various types of cameras, and their basic working principles are 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 on the light-receiving surface of the imaging device (such as the target surface of an image pickup tube), and then the imaging device converts the light into electrical energy, that is, a "video signal" is obtained. Usually, a camera is installed on an aircraft to photograph the landing gear and the taxiway, providing auxiliary video monitoring for the takeoff and landing processes. The outside of the camera is equipped with a housing to protect the camera, and the inner cavity of the housing may accumulate water over a period of time, affecting the camera components, so it is necessary to actively drain the inner cavity of the housing in a timely manner.

[0003] In the related art, the process of draining the housing is relatively complex. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. In view of this, the embodiments of the present application expect to provide a camera housing assembly, a camera device, and an aircraft to simplify the drainage process of the housing.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0026] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "top", "bottom", "upper", and "lower" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the embodiments of the present application and simplifying the description. They do not indicate or imply that the referred device or element must have a specific orientation, be constructed, operated or used in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0027] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0029] In the related art, a camera module is installed inside a housing, and the housing is provided with a drain hole through which the liquid inside the camera housing assembly can flow to the outside. The drain hole can actively control the drainage process through a drain cover. In the case of needing to drain water, removing the drain cover can enable the liquid inside the camera housing assembly to drain from the drain hole to the outside. When a large amount of liquid accumulates inside the camera housing, the liquid will exert a large pressure on the drain cover. To prevent the drain cover from being flushed away by the liquid, the operator needs to carefully control the drain cover to reduce the situation where the drain cover is flushed away. Moreover, the drain cover is usually connected to the housing through fasteners. During the process of opening the drain cover, the operator needs to hold the drain cover by hand or find a suitable storage space to prevent the drain cover from being lost, and the drainage process is relatively complex.

[0030] In this application, the drain cover 500 can be tightly pressed against the drain part 200 through the first fastener 300 and the second fastener 400 to close the communication hole 200b. When the first fastener 300 is separated from the drain part 200 and the second fastener 400 switches from the first state to the second state, the drain cover 500 can open the communication hole 200b so that the liquid in the first chamber 100a can flow from the communication hole 200b to the outside. And the abutting part 200a can inhibit the second fastener 400 from being separated from the drain part 200, so that the drain cover 500 can be hung on the drain part 200.

[0031] This application intends to provide an aircraft, including a fuselage and a camera device, and the camera device is installed on the fuselage.

[0032] Exemplarily, the aircraft is an airplane.

[0033] Exemplarily, the aircraft further includes landing gears installed on the fuselage, and the landing gears can move relative to the fuselage. The camera device is installed at the bottom of the fuselage to photograph the landing gears.

[0034] This application intends to provide a camera device. Please refer to Figure 6 and Figure 7 , the 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 installed inside 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 the first connector 920 is used to be electrically connected 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 the second connector 940 is used to be electrically connected to the sealed socket.

[0035] Exemplarily, the first connector 920 and the second connector 940 are micro rectangular connectors.

[0036] Exemplarily, the main control board 910 and the power supply board 930 are arranged at intervals in the up and down direction.

[0037] Exemplarily, the up and down direction is as Figure 2 the direction shown by the arrow R1 in

[0038] In the solution of the embodiment of the present 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 supply board 930 respectively. The wires on the main control board 910 are used to transmit image signals. The power supply and image signals are routed through the corresponding connectors, which can improve the electromagnetic compatibility reliability and reduce the degree of mutual interference of electromagnetic signals, so that the camera module 900 is relatively stable during the working process.

[0039] The present application intends to provide a camera housing 100 assembly. Please refer to Figures 1 to 3 , the camera housing 100 assembly includes a housing 100, a drainage member 200, a first fastener 300, a second fastener 400 and a drainage cover 500. The housing 100 has a first chamber 100a and a drainage hole 100b, and the drainage hole 100b is used to communicate with the outside. The drainage member 200 is installed on the housing 100, the drainage member 200 is located in the first chamber 100a, the drainage member 200 has an abutting portion 200a and a communication hole 200b, the communication hole 200b is respectively communicated with the first chamber 100a and the drainage hole 100b, and the communication hole 200b is located between the first chamber 100a and the drainage hole 100b. The first fastener 300 is detachably installed on the drainage member 200, and the second fastener 400 is installed on the drainage member 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 relatively fixed to the drainage member 200. When the second fastener 400 is in the second state, the second fastener 400 can move relative to the drainage member 200, and the abutting portion 200a is used to prevent the second fastener 400 from separating from the drainage member 200. The drainage cover 500 is covered on the drainage member 200, and the drainage cover 500 can be fixed relative to the drainage member 200 under the fastening action of the first fastener 300 and the second fastener 400 to close the communication hole 200b. When the first fastener 300 is separated from the drainage member 200 and the second fastener 400 is in the second state, the drainage cover 500 can open the communication hole 200b to communicate the drainage hole 100b with the communication hole 200b.

[0040] Exemplarily, please refer to Figure 3, the drain cover 500 has a first pressing portion 500a and a second pressing portion 500b. The first fastener 300 and the second fastener 400 respectively penetrate through the first pressing portion 500a and the second pressing portion 500b. When the first fastener 300 is installed on the drain member 200, the first pressing portion 500a is clamped by the first fastener 300 and the drain member 200. When the second fastener 400 is in the first state, the second pressing portion 500b is clamped by the second fastener 400 and the drain member 200. The first pressing portion 500a can prevent the first fastener 300 from separating from the drain cover 500. When the first fastener 300 separates from the drain member 200 and the second fastener 400 is in the second state, the first fastener 300 can hang on the drain cover 500, thereby preventing the operator from having to hold the first fastener 300 to prevent it from being lost.

[0041] Exemplarily, the housing 100 is detachably connected to the fuselage, and the drain member 200 is detachably connected to the housing 100. When the housing 100 separates from the fuselage, the first chamber 100a is visible to the outside, so that the drain member 200 located in the first chamber 100a can be repaired or replaced.

[0042] Exemplarily, the material of the drain member 200 is stainless steel. The drain member 200 has a relatively high usage rate and can provide a relatively large connection strength for the first fastener 300 and the second fastener 400.

[0043] Exemplarily, the camera device further includes a camera cable 950, and the camera cable 950 is installed in the first chamber 100a.

[0044] In the solution of the embodiment of the present application, the drain cover 500 can be fixed relative to the drain member 200 by the first fastener 300 and the second fastener 400, so as to close the connecting hole 200b. When the first fastener 300 and the drain member 200 are separated from each other, and the second fastener 400 is in the second state, the drain cover 500 can be separated from the drain member 200, so that the drain hole 100b is connected 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 abutment portion 200a of the drain member 200 can inhibit the second fastener 400 from being separated 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, and the operator can realize the drainage process of the housing 100 without the need to take the drain cover 500 by hand. Furthermore, during the drainage process, the liquid in the first chamber 100a will exert a certain degree of 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, thereby reducing the drain cover 500 from being washed away by the liquid, thereby reducing the occurrence of accidents.

[0045] In one embodiment, please refer to Figure 3 The camera housing 100 assembly also includes a sealing ring 960, which is arranged around the circumference of 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 liquid inside the first chamber 100a from flowing out from the gap between the drain member 200 and the drain cover 500, thereby reducing the liquid leakage of the camera housing 100 assembly when it is not suitable for drainage.

[0046] In one embodiment, please refer to Figures 3 to 5 The drain member 200 has a first fastening groove 200c and a first connecting groove 200d which are connected to each other. The first fastening groove 200c is located on the side of the first connecting groove 200d away from the drain hole 100b, and the groove wall of the first fastening groove 200c is formed with a thread. The first fastener 300 is a screw, and the first fastener 300 can be threadedly connected with the first fastening groove 200c. The first connecting groove 200d extends to the end surface of the drain member 200 along the direction of the first fastening groove 200c toward the drain hole 100b. The drain member 200 is threadedly connected with the first fastener 300 bracket. The installation process of the first fastener 300 and the drain member 200 is relatively simple, and the connection strength between the first fastener 300 and the drain member 200 is relatively high, which can reduce the situation that the drain cover 500 is flushed open by the liquid in the first chamber 100a, and the drainage process is relatively controllable.

[0047] Exemplarily, when projected along the arrangement direction of the first fastening groove 200c and the first communication groove 200d, the projection area of the first fastening groove 200c is located within the projection area of the first communication groove 200d.

[0048] Exemplarily, referring 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 threads that can be threadedly connected to the first fastening groove 200c. Along the length direction of the first fastener 300, the first clamping portion 300a, the first connecting portion 300b, and the first threaded portion 300c are arranged in sequence. When projected along the length direction 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 radial dimension of the first connecting portion 300b is relatively small, which enables the first fastener 300 to move relative to the drain member 200 more smoothly when the first fastener 300 and the drain member 200 are disengaged from each other, thereby reducing interference between the first fastener 300 and the drain member 200. When the first fastener 300 and the drain member 200 are fixed to each other, the first clamping portion 300a and the drain member 200 jointly clamp the first pressing portion 500a. When the first fastener 300 and the drain member 200 are disengaged from each other, the first pressing portion 500a can block the first threaded portion 300c from moving in a direction away from the first fastening groove 200c along the first communication groove 200d.

[0049] Exemplarily, the first pressing portion 500a also has threads, and the first threaded portion 300c can pass through the threads of the first pressing portion 500a so that the first threaded portion 300c passes through the first pressing portion 500a and enters the first communication groove 200d. The first fastener 300 can also be detachably connected to the drain cover 500 through the threads of the first pressing portion 500a, so that the first fastener 300 can be replaced.

[0050] It can be understood that other embodiments of the present application do not limit the connection manner between the first fastener 300 and the drain member 200. Exemplarily, the first fastener 300 can be magnetically connected to the drain member 200, and the first fastener 300 can overcome the magnetic attraction force under the action of an external force to disengage the first fastener 300 from the drain member 200.

[0051] In one embodiment, referring to Figure 3 and Figure 5, the drain member 200 has a second fastening groove 200e and a second communication groove 200f that communicate with each other. The second fastening groove 200e is located on the side of the second communication groove 200f away from the drain hole 100b. The abutting portion 200a is located at one end of the second communication groove 200f away from the second fastening groove 200e. The groove wall of the second fastening groove 200e is formed with threads. 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 method 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 member 200 is relatively high, which can further reduce the situation where the drain cover 500 is washed open by the liquid in the first chamber 100a.

[0052] Exemplarily, please refer to Figure 3 , when projected along the arrangement direction of the second fastening groove 200e and the second communication groove 200f, the projection area of the second fastening groove 200e is located within the projection area of the second communication groove 200f. Along the direction of the second fastening groove 200e towards the second communication groove 200f, the second fastening groove 200e, the second communication groove 200f, the abutting portion 200a, and the drain cover 500 are arranged in sequence.

[0053] Exemplarily, please refer to Figure 3 , the second fastener 400 includes a second clamping portion 400a, a second connecting portion 400b, and a second threaded portion 400c that are 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 in sequence. When projected along the length direction of the second fastener 400, the projection area of the second connecting portion 400b is located within the projection areas of the second clamping portion 400a and the second threaded portion 400c. The radial dimension of the second connecting portion 400b is relatively small, which can enable the second fastener 400 to move relative to the drain member 200 more smoothly when the second fastener 400 is separated 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 portion 400a and the abutting portion 200a jointly clamp the second pressing portion 500b. When the second fastener 400 is in the second state, the abutting portion 200a can prevent the second threaded portion 400c from moving along the direction away from the second fastening groove 200e from the second communication groove 200f.

[0054] Exemplarily, both the second pressing portion 500b and the abutting portion 200a have threads, and the second threaded portion 400c can thread with the second pressing portion 500b and the abutting portion 200a so that the second threaded portion 400c enters the second communication groove 200f. The second fastener 400 can also be threaded to achieve the disassembly and connection of the second fastener 400 and the drain cover 500, so that the second fastener 400 can be replaced.

[0055] In one embodiment, please refer to Figure 1 , at least part of the structure of the housing 100 is an arc surface.

[0056] Exemplarily, the shape of the bottom surface of the housing 100 is streamlined.

[0057] Exemplarily, along the direction from top to bottom, the horizontal distance between the side wall of the housing 100 and the central axis of the housing 100 gradually decreases.

[0058] In the solution of the embodiment of the present application, at least part of the structure of the housing 100 is an arc surface. During the flight of the aircraft, the housing 100 will be subjected to a certain degree of wind resistance and transfer it to the fuselage. The arc surface can reduce the wind resistance received by the housing 100 and reduce the fuel consumption of the aircraft.

[0059] It can be understood that other embodiments of the present application do not limit the shape of the housing 100. Exemplarily, the shape of the housing 100 can be a cube.
