[0002] Vehicle-mounted cameras have been widely used in vehicles such as family cars or SUVs (sports utility vehicles). In the vehicle-mounted related technologies integrated in the rearview mirror of the vehicle, the vehicle-mounted camera generally includes a camera and a fill light arranged around the periphery of the camera, and the fill light is used to fill light for the camera. However, during the use of such a vehicle-mounted camera, the light emitted by the fill light may be emitted into the field of view of the camera, resulting in stray light in the image captured by the vehicle-mounted camera. Utility Model Content

[0003] In view of this, the utility model provides a camera test bracket to solve the problem of stray light that may appear in images taken by a vehicle-mounted camera in the related art.

[0004] The utility model provides a camera test bracket, comprising:

[0005] main body;

[0006] At least one shell is arranged on the main body, a first installation cavity and a second installation cavity are formed on the shell and are suitable for installing a camera, the second installation cavity is suitable for installing a fill light, a first light-transmitting portion is arranged at a position of the shell corresponding to the first installation cavity, and a second light-transmitting portion is arranged at a position of the shell corresponding to the second installation cavity, the first light-transmitting portion and the second light-transmitting portion are arranged on the same side of the shell, and the distance between the first installation cavity and the second installation cavity is adjustable;

[0007] The connecting structure is arranged on the main body and is located at one side of the shell body where the first light-transmitting part and the second light-transmitting part are arranged, and is suitable for connecting the single-sided mirror.

[0008] Beneficial effects:

[0009] The camera test bracket of the utility model comprises a first installation cavity for installing a camera and a second installation cavity for installing a fill light. Since the first installation cavity and the second installation cavity are arranged to be distance-adjustable, the operator can adjust the distance between the camera and the fill light by adjusting the distance between the first installation cavity and the second installation cavity, so as to avoid the fill light being too close to the camera, the light of the fill light being reflected on the one-way mirror and entering the camera, causing stray light to appear in the image taken by the camera, or the fill light range of the fill light and the field of view range of the camera overlapping too little, causing the fill light to fail to achieve a fill light effect.

[0010] In addition, the camera test bracket of the present invention allows the operator to adjust the distance between the camera and the fill light to find the optimal fill light position for the camera, thereby meeting the imaging requirements of the camera. Therefore, the camera test bracket of the present invention can be applied to a variety of cameras and fill lights and has a wide range of applications.

[0011] The one-way mirror can be used to simulate the lens of a rearview mirror, with the back side of the one-way mirror facing the first mounting cavity and the second mounting cavity. By setting it in this way, the reflective surface of the one-way mirror faces outward and can be used as the mirror surface of the rearview mirror. At the same time, the light from the outside world can also be partially transmitted, allowing the light information from the outside world to pass through the one-way mirror and the first light-transmitting port in turn and hit the lens and sensor of the camera to complete the photoelectric information conversion. After the test, the camera and the fill light can be configured on the rearview mirror of the car according to the measured optimal distance. The space of the rearview mirror can be used to install the on-board camera to reduce the space occupied in the car, and the camera can be prevented from being exposed to the outside and causing psychological pressure on the passengers.

[0012] Therefore, the camera test bracket of the present invention can ensure that the fill light can effectively fill in the camera and avoid the appearance of stray light in the image taken by the vehicle-mounted camera, and has a wide range of applications.

[0069] The connecting structure 6 is arranged on the main body 1 and is located at a side of the housing where the light-transmitting portion is provided, and is suitable for connecting the single-sided mirror 903 .

[0070] The camera test bracket of the present utility model comprises a first installation cavity 201 for installing a camera 901 and a second installation cavity 301 for installing a fill light 902. The first installation cavity 201 and the second installation cavity 301 are set to be adjustable in distance, and the operator can adjust the distance between the camera 901 and the fill light 902 by adjusting the distance between the first installation cavity 201 and the second installation cavity 301, so as to avoid the fill light 902 being too close to the camera 901, the light of the fill light 902 being reflected on the one-way mirror 903 and entering the camera 901, resulting in stray light appearing in the image taken by the camera 901, or the fill light range of the fill light 902 overlapping the field of view range of the camera 901 too little, resulting in the fill light 902 being unable to play a fill light effect.

[0071] In addition, the camera test bracket of the present invention allows the operator to adjust the distance between the camera 901 and the fill light 902 to find the optimal fill light position of the fill light 902 for the camera 901, thereby meeting the imaging requirements of the camera 901. Therefore, the camera test bracket of the present invention can be applied to a variety of cameras 901 and fill lights 902 and has a wide range of applications.

[0072] The single-sided mirror 903 can be used to simulate the lens of a rearview mirror. Preferably, the back side of the single-sided mirror 903 faces the first mounting cavity 201 and the second mounting cavity 301. By such an arrangement, the reflective surface of the single-sided mirror 903 faces outward and can be used as the mirror surface of the rearview mirror. At the same time, the light from the outside world can also be partially transmitted, thereby allowing the light information from the outside world to pass through the single-sided mirror 903 and the first light-transmitting port 202 in sequence and hit the lens and sensor of the camera 901 to complete the photoelectric information conversion. After the test is completed, the camera 901 and the fill light 902 can be configured on the rearview mirror according to the measured optimal distance, so that the space of the rearview mirror can be used to install the vehicle-mounted camera 901 to reduce the occupation of the space inside the vehicle, and the camera 901 can be prevented from being exposed to the outside and causing psychological pressure on the passengers.

[0073] Therefore, the camera test bracket of the present invention can ensure that the fill light 902 can effectively fill light for the camera 901 and avoid stray light in the image captured by the vehicle-mounted camera 901, and has a wide range of applications.

The first clamping plate 601 and the second clamping plate 602 are formed with a avoidance opening 603 at positions corresponding to the first installation cavity 201 and the second installation cavity 301. The one-way mirror 903 can be clamped between the first clamping plate 601 and the second clamping plate 602, and the avoidance opening 603 can prevent the connection structure 6 from blocking the light emitted by the fill light 902 and the light incident on the camera 901.

[0075] Preferably, a reinforcing rib 604 is formed on one side of the first clamping plate 601 away from the second clamping plate 602 .

Figure 3 As shown, the first sealing ring 401 is disposed on the end surface of the first light guide ring wall 203 away from the first installation cavity 201 . The second sealing ring 402 is disposed on the end surface of the second light guide ring wall 303 away from the second installation cavity 301 .

[0101] When a single-sided mirror 903 is arranged in front of the first light guide ring wall 203 and the second light guide ring wall 303, the first light guide ring wall 203 can be closely attached to the back side of the single-sided mirror 903 through the first sealing ring 401, and the second light guide ring wall 303 can be closely attached to the back side of the single-sided mirror 903 through the second sealing ring 402, so as to reduce the loss of light and play a buffering role between the shell and the single-sided mirror 903. Preferably, the first sealing ring 401 and the second sealing ring 402 are respectively bonded to the end faces of the first light guide ring wall 203 and the second light guide ring wall 303, which can prevent the first sealing ring 401 and the second sealing ring 402 from slipping due to external bumps, thereby affecting the sealing effect and even intervening in the field of view of the camera 901 or the fill light 902. In one embodiment, the first sealing ring 401 and the second sealing ring 402 are connected in an integrated manner, which can reduce the number of parts of the camera test bracket and help simplify the process of sticking the first sealing ring 401 and the second sealing ring 402 on the shell.

[0102] In one embodiment, a cable port 5034 is formed on the shell wall of the door body 5032 or the cover shell 5031. The camera 901 may optionally be formed with a fakra (FachkreisAutomobil, audio and video transmission connector) male end, and a fakra (FachkreisAutomobil, audio and video transmission connector) harness is suitable for connecting to the fakra male end and passing through the cable port 5034 to connect to an external imaging device.

[0103] In one embodiment, Fig.10 and Fig.11 As shown, the camera test bracket further includes a connection structure 6. The connection structure 6 is disposed on the main body 1 and is located on one side of the first mounting cavity 201 and the second mounting cavity 301. The connection structure 6 is suitable for connecting the single-sided mirror 903, and the lens of the camera 901 in the first mounting cavity 201 is suitable for facing the connection structure 6.

[0104] Next, the assembly process of the rearview mirror integrated with the vehicle-mounted camera 901 of the present invention is described:

[0105] First, a suitable number of support bars 7 are selected and inserted between the first clamping plate 601 and the second clamping plate 602 , and the one-way mirror 903 is inserted onto the support bars 7 .

[0106] Next, the camera 901 is installed into the first installation cavity 201, so that the front end of the lens of the camera 901 is close to the first light transmission port 202. The fill light 902 is set on the support frame 304, and then the door body 5032 is closed to form a closed space for installing the camera 901, simulating the closed space of the rearview mirror. Double-sided tape is pasted on the bottom surface of the first shell 501, and the first sealing ring 401 is pasted on the end surface of the first light guide ring wall 203 of the first shell 501, and the second sealing ring 402 is pasted on the end surface of the second light guide ring wall 303, so that the first light guide ring wall 203 and the second light guide ring wall 303 can be closely attached to the back side of the single-sided mirror 903 through the first sealing ring 401 and the second sealing ring 402 respectively.

[0107] It should be noted that the camera 901 and the fill light 902 may be respectively disposed in the first shell 501 and the second shell 502 , or both may be disposed in the first shell 501 .

[0108] When the camera 901 and the fill light 902 are respectively arranged in the first shell 501 and the second shell 502, the operator can simulate the optimal distance between the camera 901 and the fill light 902 by adjusting the distance between the first shell 501 and the second shell 502 to find the best fill light position of the fill light 902 for the camera 901, thereby meeting the imaging requirements of the camera 901 and providing a reference for the position design of the camera 901 and the fill light 902.

[0109] Finally, one end of the Fakra harness is connected to the Fakra male end of the camera 901 through the cable port 5034 , and the other end is connected to an external imaging device to realize the imaging simulation of the camera 901 .

[0110] In one embodiment, the fill light 902 is an infrared light board, and the one-way mirror 903 is an electrochromic lens. The electrochromic lens can change the reflectivity and transmittance of infrared light and visible light when powered on.

[0111] When working during the day, the camera 901 can be in RGB color mode, can collect visible light band information, and the electrochromic lens can be in a power-off state. At this time, the electrochromic lens has a high transmittance to visible light. The visible light projected on the human body during the day can pass through the electrochromic lens and effectively reflect to the camera 901, so that the light information passes through the lens of the camera 901 and hits the receptor, completing the photoelectric information conversion. The video information of the electrical signal can be transmitted to an external imaging device through the fakra harness, so that the user can see the color information of the object through the external imaging device.

[0112] When working at night, the camera 901 can be in IR (Infrared) mode and can collect information in the infrared band. At this time, the electrochromic lens can be powered on to reduce the reflectivity and transmittance of the electrochromic lens to visible light, and maintain a high transmittance to infrared light, thereby avoiding glare in the rearview mirror when the rear vehicle turns on the headlights to illuminate the front, and playing an anti-glare effect. The fill light 902 can be turned on at night and fill light for the camera 901. Similar to visible light imaging, the black and white information of the object can be seen through the peripheral device, so that the camera 901 can monitor the passengers of the whole vehicle during the day and at night.

[0113] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
