[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The invention provides a collision warning vehicle-mounted camera device for automatic driving of a vehicle.

[0054] For the first embodiment, please refer to Figures 1 to 3 In a first embodiment of the present invention, a collision warning vehicle-mounted camera device for automatic driving of a vehicle comprises:

[0055] A mounting mechanism 1, the mounting mechanism 1 comprising a mounting frame 11 and a transparent cover 12, the transparent cover 12 being fixedly mounted on the periphery of the mounting frame 11;

[0056] A control mechanism 2, wherein the control mechanism 2 is installed in the mounting frame 11;

[0057] A first camera module 3, wherein the first camera module 3 is mounted on the control mechanism 2, and the first camera module 3 is connected to the control mechanism 2 by signals;

[0058] A connecting mechanism 4, wherein the connecting mechanism 4 is rotatably mounted on the bottom of the control mechanism 2;

[0059] A second camera module 5, wherein the second camera module 5 is mounted on the connecting mechanism 4, and the second camera module 5 is connected to the control mechanism 2 by signals;

[0060] A rotating device 6 is installed on the control mechanism 2 , and is used to drive the connecting mechanism 4 to rotate and adjust on the control mechanism 2 . The rotating device 6 is connected to the control mechanism 2 by signals.

[0061] In this embodiment, the mounting frame 11 is equipped with a mounting structure and a wiring structure (not shown) for the assembly and cable connection of the mounting frame 11. The transparent cover 12 is arranged around the periphery of the mounting frame 11 and does not affect the normal image acquisition of the first camera module 3 and the second camera module 5.

[0062] In this embodiment, the first camera module 3 is a high-definition camera unit, which provides support for image capture within a fixed range; the second camera module 5 is a high-definition camera unit, which provides support for image capture within a movable range, and the second camera module 5 adjusts the image capture direction through the rotating device 6.

[0063] By equipping the first camera module 3 with the second camera module 5, it is possible to perform a fault self-check on the camera image of the first camera module 3 before the self-driving car starts. By comparing the captured images of the two, the first camera module 3 is analyzed after the comparison to see if there is a fault in the camera image, which facilitates the self-check of the first camera module 3 before use.

[0064] When the first camera module 3 fails and cannot provide image acquisition for the autonomous driving car, the second camera module 5 can replace the first camera module 3 to prevent the autonomous driving car from being unable to operate normally after the first camera module 3 on the autonomous driving car cannot be used, thereby providing support for stable image acquisition for the autonomous driving car;

[0065] When the first camera module 3 is in good working order, the second camera module 5 can adaptively adjust the camera direction of the second camera module 5 when the autonomous driving vehicle turns, so as to provide a turning field of view for the autonomous driving vehicle; the second camera module 5 can also adjust the direction of image acquisition according to application requirements, so as to be used for image acquisition and monitoring of the internal driving environment of the autonomous driving vehicle.

[0066] Please refer to Figure 2 and Figure 4 The control mechanism 2 includes a housing 21, a control module 22, a data comparison module 23 and a data analysis module 24. The housing 21 is fixed in the mounting frame 11, the control module 22 is fixed in the housing 21, and the data comparison module 23 and the data analysis module 24 are both signal-connected to the control module 22;

[0067] The first camera module 3 is connected to the control module 22 by signal, the second camera module 5 is connected to the control module 22 by signal, and the rotating device 6 is connected to the control module 22 by signal.

[0068] In this embodiment, a wiring terminal (not shown) is installed between the housing 21 and the mounting frame 11 for power supply and signal connection of the control mechanism 2 as a whole, so that the vehicle system can establish a signal connection with the control mechanism 2.

[0069] The data comparison module 23 is used to compare the similarity of the image clarity captured by the first camera module 3 and the second camera module 5 in the self-test mode; the data analysis module 24 is used to analyze whether the first camera module 3 has a fault based on the comparison result, so as to provide technical support for the safety of equipment operation.

[0070] When the first camera module 3 performs self-test:

[0071] First, the second camera module 5 is controlled by the rotating device 6 to rotate to the same image acquisition direction as the first camera module 3;

[0072] Simultaneously start the first camera module 3 and the second camera module 5, and compare and analyze the clarity and range of the images captured by the two;

[0073] If the clarity similarity is greater than or equal to 95%, it is determined that the first camera module 3 operates normally and has no faults;

[0074] If the clarity similarity is less than 95%, it is determined that the image of the first camera module 3 is faulty.

[0075] When the first camera module 3 self-checks and has no faults, the second camera module 5 can perform steering adjustment to expand the steering angle of the autonomous driving vehicle and can also be used to monitor the interior environment of the autonomous driving vehicle;

[0076] When the first camera module 3 self-detects a fault, the second camera module 5 remains in the image acquisition range of the first camera module 3 and cannot be used for steering; it is used to replace the first camera module 3 to perform image acquisition work for the driverless car.

[0077] Specifically, the second camera module 5 includes two usage modes:

[0078] In the camera self-check mode, the second camera module 5 provides support for the image self-check before the first camera module 3 is started; it is convenient for the first camera module 3 to self-check faults before use;

[0079] In the auxiliary viewing angle mode, the second camera module 5 increases the steering viewing angle range when the autonomous driving vehicle turns; and facilitates providing steering viewing angle support for the blind spot of the viewing angle of the first camera module 3 when the autonomous driving vehicle turns.

[0080] For details, please refer to Figure 5The rotating device 6 includes a driving member 61, a gear 62 and a ring gear 63. The driving member 61 is mounted on the housing 21. The shaft end of the driving member 61 passes through the housing 21 and is fixedly connected to the gear 62. The ring gear 63 is fixedly mounted on the connecting mechanism 4. The gear 62 is meshed with the ring gear 63.

[0081] The driving member 61 is connected to the control module 22 via a signal.

[0082] In this embodiment, the driving member 61 is a driving motor, and the shaft end of the driving member 61 is rotatably connected to the housing 21. The driving member 61 is used to drive the gear 62 to rotate. When the gear 62 rotates, it can drive the ring gear 63 to rotate. The ring gear 63 synchronously drives the connecting mechanism 4 to rotate, thereby adjusting and switching the visual direction of the second camera module 5, and providing power for switching the second camera module 5 in different modes.

[0083] Specifically, the second camera module 5 also includes an in-vehicle monitoring mode, and the second camera module 5 provides monitoring and safety surveillance for the user situation in the vehicle.

[0084] When the second camera module 5 does not need to expand the turning angle and self-check, the angle of view of the second camera module 5 can be controlled to switch to a state facing the interior of the autonomous driving vehicle, so as to monitor the user status of the main driver's seat or the co-driver's seat in the autonomous driving vehicle.

[0085] Provide safety monitoring support for the environmental safety of users inside autonomous vehicles to ensure the safety of passengers or drivers.

[0086] The working principle of the collision warning vehicle-mounted camera device for automatic driving of a vehicle provided in this embodiment is as follows:

[0087] A1, when it is necessary to perform a self-test on the first camera module 3, the driving member 61 is first started, the driving member 61 drives the gear 62 to rotate, the gear 62 drives the gear ring 63 to rotate, and the connecting mechanism 4 and the second camera module 5 are controlled to control the viewing direction until the viewing direction of the second camera module 5 is consistent with the viewing direction of the first camera module 3;

[0088] A2, during self-check, the first camera module 3 and the second camera module 5 are started, and two sets of picture acquisition data are obtained at the same time. The data comparison module 23 compares the two sets of picture acquisition data, and the data analysis module 24 analyzes the comparison results to determine whether the first camera module 3 has a fault;

[0089] S3, when the first camera module 3 fails, the second camera module 5 maintains the viewing angle direction of the self-check mode to replace the first camera module 3 to collect the automatic driving picture;

[0090] A4, when the first camera module 3 is not faulty, the second camera module 5 can choose to expand the steering angle or monitor the in-vehicle image according to the use requirements.

[0091] For the second embodiment, please refer to Figures 8 to 9 Based on the collision warning vehicle-mounted camera device for automatic vehicle driving provided by the first embodiment of the present invention, the second embodiment of the present invention proposes another collision warning vehicle-mounted camera device for automatic vehicle driving. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0092] Specifically, the difference of the collision warning vehicle-mounted camera device for automatic driving of a vehicle provided by the second embodiment of the present invention is that the connecting mechanism 4 includes a fixed tube 41, a telescopic member 42 and a lifting cover 43, the top of the fixed tube 41 is rotatably mounted on the bottom of the housing 21, the fixed part of the telescopic member 42 is fixed on the housing 21 through a connecting rod 211, the telescopic part of the telescopic member 42 is rotatably connected to the lifting cover 43, and the lifting cover 43 is slidably mounted on the fixed tube 41;

[0093] The second camera module 5 is mounted on the lifting cover 43 , and the lifting cover 43 is frictionally connected to the connecting portion of the fixing tube 41 .

[0094] In this embodiment, the telescopic member 42 is an electric telescopic structure, which is used to drive the lifting cover 43 to rise and fall relative to the fixed tube 41;

[0095] When the lifting cover 43 is retracted, the second camera module 5 is located within the range of the mounting frame 11, which facilitates switching between the camera self-check mode, the auxiliary viewing angle mode and the in-vehicle monitoring mode;

[0096] When the lifting cover 43 is unfolded, the second camera module 5 is located outside the mounting frame 11, providing a pancake mode for the autonomous driving vehicle, and providing a sentinel mode when the autonomous driving vehicle is in a closed state, for capturing surround images within the vehicle environment.

[0097] Please refer again Figure 8 A slide groove 411 is provided on the fixed tube 41 , a slider 431 is fixed on the lifting cover 43 , and the slider 431 is inserted into the slide groove 411 and is slidably connected with the fixed tube 41 .

[0098] The stability of the sliding connection between the lifting cover 43 and the fixed tube 41 is increased; the fixed tube 41 is ensured to stably drive the lifting cover 43 to rotate synchronously during rotation adjustment, and a stable power source is provided for the rotation adjustment of the second camera module 5.

[0099] Please refer again Figure 8 The collision warning vehicle-mounted camera device for automatic driving of a car also includes a cleaning mechanism 7, which includes a lifting member 71 and a brush plate 72. The lifting member 71 is installed in the mounting frame 11, and the brush plate 72 is fixed to the lifting part of the lifting member 71. The lifting member 71 is used to drive the brush plate 72 to rise and fall; the brush plate 72 is attached to the surface of the first camera module 3.

[0100] In this embodiment, the surface of the brush plate 72 is attached to the surface of the first camera module 3; when the brush plate 72 is retracted, it does not affect the normal operation of the first camera module 3; the lifting member 71 is used to drive the brush plate 72 to rise and fall, so that the brush plate 72 can wipe and clean the camera surface of the first camera module 3, which is used for automatic maintenance of the first camera module 3.

[0101] Specifically, the brush plate 72 is a double-sided cleaning structure, one side of which is attached to the first camera module 3, and the other side of which is attached to the surface of the transparent cover 12. It is convenient to clean and maintain the first camera module 3 and the transparent cover 12 while adjusting the brush plate 72, thereby extending the service life of the equipment.

[0102] In an optional implementation of the present embodiment, the lifting member 71 is an electric telescopic structure, the fixed end of the lifting member 71 is fixedly connected to the mounting frame 11, the telescopic part of the lifting member 71 is fixedly connected to the brush plate 72, and the lifting member 71 is used to directly drive the brush plate 72 to lift and lower.

[0103] In another optional implementation manner of the present embodiment, the lifting member 71 is an L-shaped connection structure, and the lifting cover 43 is sleeved on the bottom of the lifting member 71 and is rotatably connected.

[0104] In this embodiment, the bottom of the lifting member 71 is rotatably mounted on the top of the lifting cover 43 , and the lifting member 71 is arranged around the first camera module 3 . The lifting member 71 and the brush plate 72 can only be lifted and lowered on the first camera module 3 .

[0105] When the lifting cover 43 switches from the retracted state to the unfolded state, the lifting cover 43 can also synchronously drive the lifting member 71 and the brush plate 72 to rise and fall, thereby ultimately achieving adaptive cleaning and maintenance of the first camera module 3 while the second camera module 5 switches modes.

[0106] The working principle of the collision warning vehicle-mounted camera device for automatic driving of a vehicle provided in this embodiment is as follows:

[0107] like Figure 8 As shown, it may be defined that in the initial state, the second camera module 5 is in the self-checking mode, the lifting cover 43 is in the retracted state, and the brush plate 72 is in the retracted state;

[0108] Please refer to Figures 8 to 10 When the sentry mode of the second camera module 5 is needed, the telescopic member 42 is started, and the telescopic member 42 drives the lifting cover 43 to move downward, so that the lifting cover 43 switches from the retracted state to the deployed state;

[0109] When the lifting cover 43 is unfolded, the lifting cover 43 simultaneously drives the second camera module 5 to move downward and out of the range of the mounting frame 11, so that the second camera module 5 can be rotated and adjusted in all directions without blind spots in the sentinel mode, and is used for monitoring the all-round viewing angle of the autonomous driving car in the sentinel mode;

[0110] When the lifting cover 43 is unfolded, the lifting cover 43 also drives the lifting member 71 and the brush plate 72 to move downward. When the brush plate 72 moves downward, the first camera module 3 and the transparent cover 12 in a non-working state are adaptively cleaned and maintained, so as to facilitate adaptive maintenance of the equipment.

[0111] like Fig.10 As shown, the second camera module 5 is in the sentry mode, the lifting cover 43 is in the deployment mode, and the brush plate 72 is in the downward state.

[0112] Finally, under the action of the same driving power, the second camera module 5 is switched from the retracted state to the unfolded state, and the first camera module 3 and the transparent cover 12 are adaptively cleaned and maintained simultaneously.

[0113] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
