Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted camera technology, and in particular to a vehicle-mounted camera module structure. Background Art

[0002] At a time when road traffic safety is receiving much attention, traffic accidents caused by driver fatigue driving, distracted driving and other behaviors are common. In order to effectively reduce such risks, the driver monitoring system (DMS) came into being. It uses cameras, sensors and other equipment to monitor the driver's facial expressions, eye conditions, head movements, etc. in real time, and can accurately determine whether the driver is yawning, closing eyes for too long, looking away from the road and other fatigue or distraction conditions. With the gradual development of intelligent driving technology and the improvement of vehicle automation, DMS has become an important part of ensuring driving safety. By reminding drivers in time to avoid dangerous situations, it is playing an increasingly critical role in the field of automobile safety. The camera module structure is an important part of the driver monitoring system, which is used to monitor the driver's driving posture at all times. The A-pillar of the vehicle close to the driver is the best position for installing the camera module structure. The cross-section of the vehicle's A-pillar is usually a polygonal tubular structure. Various wiring harnesses, drain pipes, sealing strips and other components are also arranged inside the A-pillar, which makes the internal remaining space of the A-pillar small. Since the existing vehicle-mounted camera module structure is large in size and cannot be directly installed in the vehicle's A-pillar, the camera module structure can usually only be installed on the outer surface of the decorative cover wrapped around the outside of the A-pillar, which affects the overall appearance of the vehicle interior and to a certain extent blocks part of the driver's line of sight, resulting in an increase in the driving blind spot. Summary of the invention

[0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: to provide a vehicle-mounted camera module structure to solve the problem that the vehicle-mounted camera module in the prior art can usually only be installed outside the A-pillar due to its large size.

Therefore, the vehicle-mounted camera module structure of the above scheme can be installed in the A-pillar of the vehicle, without affecting the overall aesthetics of the interior of the vehicle and without blocking the driver's line of sight.

[0006] Furthermore, a first mounting cavity for mounting the front-end circuit board is formed on a side of the first mounting portion facing away from the first side wall of the A-pillar, the front-end circuit board is arranged in the first mounting cavity and is detachably connected to the shell, the first mounting cavity penetrates the first mounting portion in a direction away from the first side wall of the A-pillar to form a first window, a light-transmitting plate is provided on the first window cover, and a second mounting cavity for mounting the rear-end circuit board is formed on a side of the second mounting portion facing the second side wall of the A-pillar, the rear-end circuit board is arranged in the second mounting cavity and is detachably connected to the shell, the second mounting cavity is communicated with the first mounting cavity, and the second mounting cavity penetrates the second mounting portion in a direction toward the second side wall of the A-pillar to form a second window, and an end cover plate is provided on the second window cover.

[0007] Furthermore, the light-transmitting plate includes an infrared cover plate, a limiting boss is protruded on the infrared cover plate in a direction away from the first mounting portion, and a first mounting step for mounting the infrared cover plate is provided around the first window. When the infrared cover plate is mounted on the first mounting step, the surface of the infrared cover plate is flush with the surface of the first mounting portion. The infrared cover plate is bonded to the first step. When the housing is mounted on the A-pillar, a second mounting hole that cooperates with the limiting boss is opened on the decorative cover outside the A-pillar, and the limiting boss extends out of the decorative cover through the second mounting hole on the decorative cover.

[0008] Furthermore, a second mounting step for mounting the rear-end circuit board is provided in the second mounting cavity, a mounting column flush with the end surface of the second window is provided on the inner wall of the second mounting cavity, a threaded hole is provided on the mounting column, and when the end cover plate is placed on the end surface of the second window to cover the second window, the outer wall of the end cover plate is flush with the outer wall of the shell.

[0013] Furthermore, the housing is a metal housing, and the partition is a metal plate integrally formed with the housing. In addition to blocking infrared light, the metal partition can also reduce the heat at the lens and quickly transfer it to the housing for heat dissipation, thereby increasing the heat dissipation capacity and preventing the temperature at the lens from being too high, causing imaging distortion.

Therefore, the vehicle-mounted camera module structure of the above solution can be installed in the A-pillar 60 of the vehicle without affecting the overall aesthetics of the interior of the vehicle and blocking the driver's line of sight.

[0042] Combination Figure 3-Figure 7As shown, the first mounting portion 101 and the second mounting portion 102 are integrally formed to form the entire housing 10, and a first mounting cavity 1011 for mounting the front-end circuit board 21 is provided on a side of the first mounting portion 101 away from the first side wall 601 of the A-pillar 60, and the front-end circuit board 21 is arranged in the first mounting cavity 1011 and is detachably connected to the housing 10, and the first mounting cavity 1011 penetrates the first mounting portion 101 in a direction away from the first side wall 601 of the A-pillar 60 to form a first window 1012, and a light-transmitting plate is provided on the first window 1012. In this embodiment, the light-transmitting plate is an infrared cover plate 40, and the infrared cover plate 40 has good infrared transmittance, which is conducive to infrared monitoring, and a limiting boss 401 is convexly provided on the infrared cover plate 40 in a direction away from the first mounting portion 101.

When the infrared cover 40 is mounted on the first mounting step 1013, the surface of the infrared cover 40 is flush with the surface of the first mounting portion 101. In this embodiment, the infrared cover 40 is mounted on the first mounting step 1013 by bonding. When the entire housing 10 is mounted on the A-pillar 60, a second mounting hole 701 cooperating with the limiting boss 401 is provided on the decorative cover 70 outside the A-pillar 60. The limiting boss 401 extends out of the decorative cover 70 through the second mounting hole 701 on the decorative cover 70. Continue reading Figure 3-Figure 7 As shown, a second mounting portion 102 is provided with a second mounting cavity 1021 for mounting the rear end circuit board 22 on one side of the second mounting portion 102 facing the second side wall 602 of the A-pillar 60, and the rear end circuit board 22 is arranged in the second mounting cavity 1021 and is detachably connected to the shell 10, the second mounting cavity 1021 is communicated with the first mounting cavity 1011, and the second mounting cavity 1021 passes through the second mounting portion 102 in the direction of the second side wall 602 of the A-pillar 60 to form a second window 1022, and the second window 1022 is covered with an end cover plate 30, and a mounting lug 103 is provided on the outer wall of the shell 10 close to the light-transmitting plate, and a mounting hole three 1031 is provided on the mounting lug 103. After the shell 10 is inserted into the A-pillar 60, the entire shell 10 can be fixedly connected to the A-pillar 60 through the mounting hole three 1031 by screws.

[0043] like Figure 4As shown, a second mounting step 1023 for mounting the rear circuit board 22 is provided in the second mounting cavity 1021, and the height of the second mounting step 1023 is set so that when the rear circuit board 22 is mounted on the second mounting step 1023, the rear circuit board 22 does not protrude out of the second mounting cavity 1021, and a mounting column 1024 flush with the end surface of the second window 1022 is provided on the inner wall of the second mounting cavity 1021, and a threaded hole is provided on the mounting column 1024, and a threaded hole is provided on the end cover plate 30. 4, when the end cover plate 30 is covered on the end surface of the second window 1022 to cover the second window 1022 and the end cover plate 30 is fixedly connected to the shell 10 by screws, the outer wall of the end cover plate 30 is flush with the outer wall of the shell 10. In this solution, a threaded hole is provided on the second mounting step 1023, and a through hole matching the threaded hole on the second mounting step 1023 is provided on the rear end circuit board 22, and the rear end circuit board 22 can be mounted on the second mounting step 1023 by screws.

[0044] Combination Figure 5 As shown, the front circuit board 21 includes a first mounting circuit board 211 and a first connecting circuit board 212. The first mounting circuit board 211 is arranged parallel to the first side wall 601 on the A-pillar 60. One end of the first connecting circuit board 212 is electrically connected to the first mounting circuit board 211, and the other end of the first connecting circuit board 212 is electrically connected to the rear circuit board 22. The lens 31 and the photosensitive chip are both arranged on the first mounting circuit board 211. In this solution, the first connecting circuit board 212 preferably adopts a flexible circuit board. Of course, in some other embodiments, the first connecting circuit board 212 can also be implemented by a rigid circuit board or a circuit board combining rigidity and flexibility.

[0045] Continue reading Figure 5 The camera assembly also includes an infrared light 32 disposed on the first mounting circuit board 211. By disposing the infrared light 32, infrared imaging can be realized to monitor the driver in real time in a dark environment at night. A mounting groove 2111 is disposed on the first mounting circuit board 211. The mounting groove 2111 penetrates the first mounting circuit board 211 along the thickness direction of the first mounting circuit board 211. The infrared light 32 is located on one side of the mounting groove 2111, and the lens 31 is located on the other side of the mounting groove 2111. Figure 6As shown, a partition 1014 cooperating with the mounting groove 2111 is provided in the first mounting cavity 1011. When the first mounting circuit board 211 is installed in the first mounting cavity 1011, the partition 1014 is inserted into the mounting groove 2111 to isolate the infrared light emitting lamp 32 from the lens 31. Due to the isolation of the partition 1014, the partition 1014 blocks the infrared light emitted by the infrared light emitting lamp 32 to prevent the infrared light emitted by the infrared light emitting lamp 32 from directly irradiating the lens 31 and interfering with the real-time monitoring of the driver by the lens 31. The projection area of ​​the limiting boss 401 on the infrared cover plate in the direction of the first circuit board is sufficient to cover the infrared light emitting lamp 32 and the lens 31, so that the infrared light generated by the infrared light emitting lamp 32 can be emitted through the limiting boss 401 to the outside of the decorative cover 70 to irradiate the driver, and it can also ensure that the infrared light reflected from the outside can pass through the limiting boss 401 into the first mounting cavity 1011 and be captured by the lens 31. In this solution, the shell 10 can be made of metal such as aluminum and steel, preferably aluminum. The partition 1014 is a metal plate integrally formed with the shell 10. In addition to blocking infrared light, the metal partition 1014 can also reduce the heat at the lens 31 and quickly conduct it to the shell 10 for heat dissipation, thereby increasing the heat dissipation capacity to prevent the temperature at the lens 31 from being too high, causing imaging distortion.

[0046] Combination Figure 2 , Figure 6 As shown, the transmission component includes a power connection terminal 51 and a data connection terminal 52, both of which are electrically connected to the rear-end circuit board 22. The shell 10 is provided with a first bayonet 1025 and a second bayonet 1026 which are respectively engaged with the power connection terminal 51 and the data connection terminal 52. The power connection terminal 51 is used to supply power to the front-end circuit board 21 and the rear-end circuit board 22. The data connection terminal 52 is connected to an external vehicle-mounted processor for transmitting image information captured by the lens 31 to the vehicle-mounted processor for analysis and processing.

[0047] In the present solution, by setting the shell 10 for installing the camera component, circuit component and transmission component into a special-shaped structure that matches the shape of the vehicle's A-pillar 60, other components in the vehicle's A-pillar 60 are effectively avoided, and the vehicle-mounted camera module structure can be installed in the vehicle's A-pillar 60; by integrating the lens 31 and the infrared light emitting lamp 32 on a circuit board, the overall size of the module is effectively reduced, and it is convenient to install in the A-pillar 60; a metal partition 1014 is provided in the shell 10, and a mounting groove 2111 that cooperates with the partition 1014 is provided on the circuit board that integrates the lens 31 and the infrared light emitting lamp 32. The metal partition 1014 prevents the infrared light emitted by the infrared light emitting lamp 32 from interfering with the lens 31 while enhancing the heat dissipation effect on the environment of the lens 31, thereby improving the imaging quality.

[0048] The above embodiments only express the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
