[0022] This utility model discloses an airtightness testing device for a vehicle-mounted camera. The receiving component has an internal testing chamber for holding the camera, which is filled with a colored liquid. The camera is completely submerged below the liquid surface. An air source is connected to the receiving component via a ventilation assembly. A pressure regulating component adjusts the pressure of the gas introduced into the testing chamber.

[0037] According to a first aspect of the present invention, an airtightness testing device for a vehicle camera is provided, which includes a receiving component 10, a ventilation component, and an air source.
[0038] The specific structure of the above-mentioned components of the vehicle-mounted camera airtightness detection device according to this embodiment will be described below.
[0039] In this embodiment, as Figure 1 and Figure 2 As shown, the receiving part 10 has a detection cavity 112 for holding the camera inside. The detection cavity 112 is filled with a colored liquid. The colored liquid in the detection cavity 112 can be water with added dye or water with added colored powder. The camera is completely submerged below the surface of the liquid to ensure that the liquid can completely submerge the camera and avoid the situation where the camera leaks due to the liquid not being able to reach it.
[0040] In this embodiment, as Figure 1As shown, the ventilation assembly is connected to the receiving part 10. Specifically, the ventilation assembly includes a pipe 21 connected to the detection chamber 112 and a pressure regulating component 22 disposed on the pipe 21. The pipe 21 can be a flexible hose, such as a rubber hose, or a rigid pipe, such as a steel pipe. The pressure regulating component 22 can be a pressure regulating valve, and the pressure regulation method can be manual or electronic. The air source is connected to the receiving part 10 via the ventilation assembly to introduce gas into the detection chamber 112. The air source can be a compressed air tank. The pressure of the gas introduced into the detection chamber 112 is regulated by the pressure regulating component 22. The gas applies pressure to the liquid. If the camera leaks, the liquid outside the camera will enter the internal cavity of the camera. Therefore, the generation of bubbles can indicate the location of the leak. After the camera is removed, it is possible to observe whether there is residual dye at the connection point between the two components in the camera. The detection is convenient and fast, and the test results are more intuitive and reliable, thereby ensuring the normal use of the camera.
[0041] It should be noted that in this embodiment, the camera only needs to be immersed in the liquid; it is not necessary to fill the detection chamber 112 with liquid, to avoid excessive pressure caused by the combined effect of gas and liquid pressure, which could damage the camera. In a preferred embodiment, the camera can be placed in the detection chamber 112 first, and then colored liquid can be introduced into it until the liquid level exceeds the top of the camera, thus saving detection costs.
[0042] In a preferred embodiment, the liquid contains fluorescent powder. When bubbles are found after pressurization, the camera is removed from the detection chamber 112, dried, and then disassembled. The location of the leak can be visually indicated by observing the inside of the camera and the connection point between the two components under a UV lamp.
[0043] It should be noted that when air bubbles are present, micropores or cracks may not be visible with ultraviolet light. Therefore, it is necessary to slice the part with an ultrasonic scalpel and reconstruct the leakage path using an integration method. Compared with existing detection devices and methods, the results of the vehicle-mounted camera airtightness detection device of this application are more informative.
[0044] It should be further noted that when the color in the liquid is a dye, it can be directly removed after pressurization and subjected to air slicing.
[0045] In this embodiment, a transparent area is provided on the receiving component 10 to form a viewing window, so that it is possible to directly observe from the outside of the receiving component 10 whether bubbles appear in the camera and the location of the bubbles when gas is introduced. The receiving component 10 can be formed as a transparent shell structure (e.g., a shell structure made of glass or plastic), or a viewing window can be formed on a local side wall of the receiving component 10 using a strip of transparent plate made of materials such as glass or acrylic.
[0046] In this embodiment, as Figure 2 As shown, a connecting hole 122 is provided on the receiving component 10, which connects the detection chamber 112 and the outside of the receiving component 10. Furthermore, the ventilation assembly also includes a connector 23 installed in the connecting hole 122. Both ends of the pipeline 21 on the gas delivery path are connected to the connector 23 and the gas source, respectively. Part of the connector 23 extends into the connecting hole, and part of the connector 23 extends out of the receiving component 10. The connector 23 is preferably a bent connector 23, which facilitates the spatial layout of the device when the pipeline 21 is a rigid pipe, and also facilitates the connection between the ventilation assembly and the receiving component 10.
[0047] In a preferred embodiment, such as Figure 2 As shown, connector 23 is sealed to the connecting hole 122 to ensure the sealing of the connection between connector 23 and the receiving part 10, and to ensure that the introduced gas can effectively pressurize the liquid in the detection chamber 112. In an optional embodiment, connector 23 and connecting hole 122 are interference-fitted. In another optional embodiment, a sealing ring is provided between connector 23 and connecting hole to achieve a sealed connection.
[0048] In this embodiment, as Figure 1 and Figure 2 As shown, the receiving component 10 includes a base 11 and a cover 12, which facilitates the insertion and removal of the camera from the detection chamber 112. The base 11 is located below the cover 12, and the detection chamber 112 is located on the base 11. The opening of the detection chamber 112 is located on the top of the base 11, and the base 11 is formed into a cylindrical structure. The cover 12 is detachably connected to the base 11 and the cover 12 can close the opening, so that the detection chamber 112 forms a closed cavity. The connecting hole 122, as described above, can be provided on the cover 12. The axis of the connecting hole 122 is vertically arranged, so that the pressure direction of the gas is vertically downward.
[0049] Furthermore, in this embodiment, a transparent area as described above is formed on the base 11.
[0050] Preferably, such as Figure 2 As shown, the thickness of the bottom wall of the base 11 is greater than the thickness of the side wall of the base 11, thus improving the stability of the support 10.
[0051] In a preferred embodiment, such as Figure 2 As shown, the vehicle-mounted camera airtightness testing device also includes a sealing element 30 sandwiched between the cover 12 and the base 11 to seal the gap between the cover 12 and the base 11, ensuring that the detection cavity 112 is not connected to the outside of the receiving component 10 after the cover 12 is installed on the base 11. The sealing element 30 can be an elastic sealing ring.
[0052] Preferably, the sealing element 30 is sandwiched between the cover 12 and the base 11 along the direction in which the gas enters the detection chamber 112. For example, when the pressure direction of the gas in the detection chamber 112 is vertically downward, the sealing element 30 is formed into a closed annular structure and is disposed on the top of the base 11. The side of the sealing element 30 away from the base 11 is pressed against the cover 12.
[0053] Furthermore, in this embodiment, as Figure 2 As shown, the circumferential edge of the cover 12 has a covering portion 121 extending toward the base 11. The covering portion 121 surrounds the circumferential sidewall of the top of the base 11, thereby improving the tightness of the assembly between the cover 12 and the base 11. Preferably, the covering portion 121 is threadedly connected to the outer wall of the base 11.
[0054] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, an outwardly extending support portion 111 is formed on the side wall at the bottom of the base 11. The support portion 111 is preferably formed in a ring structure to increase the contact area between the base 11 and the test platform or detection platform, ensuring the stability of the base 11 and preventing the support member 10 from tipping over during the testing process. Preferably, as shown... Figure 2 As shown, the thickness of the support 111 is the same as the thickness of the bottom of the base 11.
[0055] According to the present invention, the airtightness testing device for a vehicle-mounted camera has a testing chamber formed inside the receiving component for holding the camera. The testing chamber is filled with a colored liquid, and the camera is completely immersed below the liquid surface. The air source is connected to the receiving component through a ventilation component, and the pressure of the gas introduced into the testing chamber is adjusted by a pressure regulating component. If the camera leaks, the liquid outside the camera will enter the cavity inside the camera, and the resulting bubbles can indicate the location of the leak. After the camera is removed, it can be observed whether there is any residual colorant at the connection point between the two components inside the camera. If there is any residue, it indicates a leak. The detection is convenient and fast, and the test results are more intuitive and reliable, thereby ensuring the normal use of the camera.
[0056] The second aspect of this utility model provides a vehicle equipped with a camera that has been tested by an essential oil vehicle camera airtightness detection device. The camera's detection results are accurate and reliable, ensuring the normal use of the vehicle and improving its driving safety.
[0057] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
