Technical Field

[0001] The utility model relates to the technical field of automobile accessories, and particularly relates to a safety camera device for autonomous driving. Background Art

[0002] Autonomous driving, also known as driverless driving, means that a car can complete environmental perception and navigation and reach the destination smoothly without the control of a driver. The realization of autonomous driving depends on a variety of advanced technologies, including sensor technology, chip technology, operating system and network technology, etc. The camera devices for autonomous driving are one of the crucial sensors in autonomous vehicles. They are responsible for capturing high-definition images of the vehicle's surrounding environment and providing visual perception data for the autonomous driving system.

[0003] In the patent with the publication number of CN212022522U, a camera device for autonomous vehicles is disclosed, which includes a fixed block and a camera function body. A groove is formed on the rear surface of the fixed block, and first rotating shafts are rotatably installed on both sides inside the groove. Clips are fixedly installed on the surfaces of the first rotating shafts. An inclined block is fixedly installed on the front surface of the fixed block. A receiving groove is formed at the bottom end of the inclined block, and a baffle is inserted into the receiving groove. 3M glue is pasted on the top end of the inclined block. A second rotating shaft is fixedly installed on one side of the fixed block, and the camera function body is rotatably installed on the side surface of the second rotating shaft. A display screen is provided on the rear surface of the camera function body, and buttons are provided on one side of the display screen.

[0004] Since there is no protection measure for the camera function body in the above patent, in case of unexpected situations such as sudden car accidents, the camera function body will collide with the external environment and be damaged, resulting in data loss in the records. Therefore, we have designed a safety camera device for autonomous driving to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a safety camera device for autonomous driving to solve the problem that when unexpected situations such as sudden car accidents occur, the camera body collides with the external environment and is damaged, resulting in data loss in the records.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A safety camera device for autonomous driving includes an installation shell. Connecting blocks are provided on all four sides of the installation shell. An acceleration sensor is provided on the outer wall of the installation shell. Protection components are symmetrically provided on the installation shell. The protection components include a first controller, a rotating shaft, a rotating plate, a first motor and a first transmission belt. The first controller is arranged on the inner wall of the installation shell and is electrically connected to the acceleration sensor. The rotating shaft is arranged on the outer wall of the installation shell. The rotating plate is arranged on the outer wall of the rotating shaft. The motor is arranged on the inner wall of the installation shell, and the first motor is electrically connected to the first controller. The first transmission belt is arranged on the outer walls of the rotating shaft and the output shaft of the first motor. A camera component is arranged inside the installation shell.

[0007] The beneficial effects of this solution are as follows: By detecting whether a collision occurs during the vehicle's driving through an acceleration sensor, the signal is transmitted to the first controller, and then the first motor is started by the first controller, so that the first transmission belt drives the rotating shaft to rotate, and then the rotating plate is driven by the rotating shaft to rotate and cover the opening of the mounting shell, thereby cooperating with the mounting shell to protect the camera assembly, preventing the camera assembly from colliding with the external environment and being damaged, and causing data loss.

[0008] Preferably, as an improvement, the camera assembly includes two groups of bases. Each group of bases includes two mounting blocks. A first rotating rod is commonly provided between the two groups of bases. The outer wall of the first rotating rod is symmetrically provided with first connecting rods. At the opposite ends of the two first connecting rods, second rotating rods are provided. At the mutually approaching ends of the two second rotating rods, second connecting rods are provided.

A second controller is provided at the inner bottom of the mounting shell. The second controller is electrically connected to the acceleration sensor, and the second motor is electrically connected to the second controller.

[0009] The beneficial effects are as follows: By starting the second motor to drive the second transmission belt, the second connecting rod rotates around the second rotating rod, so that the camera body extends out of the mounting shell, thereby enabling the camera body to have a better shooting angle. When the second controller receives the signal from the acceleration sensor, the second motor drives the second transmission belt, so that the second connecting rod rotates around the second rotating rod, thereby driving the camera body to move towards the inside of the mounting shell, and finally the camera body is received into the mounting shell for protection.

[0010] Preferably, as an improvement, a cylinder is provided on the inner wall of the mounting shell. The output end of the cylinder is provided with a moving block, and the top of the moving block is respectively in contact with the two first connecting rods.

A third controller is provided on the outer wall of the support base. The third controller is electrically connected to the acceleration sensor, and the cylinder is electrically connected to the third connector.

[0011] The beneficial effects are as follows: By the cylinder pushing the moving block, the first connecting rod is lifted upwards, thereby increasing the height of the second connecting rod, which is beneficial to quickly extending the camera assembly out of the mounting shell.

[0012] Preferably, as an improvement, two first torsion springs are provided on the outside of the first rotating rod, and the two first torsion springs are respectively located between each group of bases. One end of the first torsion spring is connected to the mounting block, and the other end is connected to the first connecting rod.

[0013] The beneficial effects are as follows: The first torsion spring can reset the first connecting rod, and at the same time can play a shock-absorbing role for the first connecting rod, preventing the camera component from shaking in the installation shell and causing damage to the camera component.

[0014] Preferably, as an improvement, rotating blocks are symmetrically arranged on the outer wall of the camera body, and the two rotating blocks are respectively rotatably connected to the adjacent second connecting rods.

Disks are provided at the ends of the two second torsion springs away from the camera body, and the disks are slidably sleeved on the outer walls of the rotating blocks, and the disks are abutted against the first connecting rod.

[0015] The beneficial effects are as follows: By the second torsion spring squeezing the disk, the disk is caused to squeeze the outer wall of the second connecting rod, thereby fixing the camera body and increasing the stability of shooting.

[0016] Preferably, as an improvement, a plurality of protrusions are provided at the mutually remote ends of the two disks, and grooves matching the protrusions are respectively formed at the opposite ends of the two second connecting rods.

[0017] The beneficial effects are as follows: Through the mutual cooperation between the protrusions and the grooves, the disk and the second connecting rod can be more closely attached, further increasing the shooting stability of the camera body, and at the same time facilitating the adjustment of the shooting angle of the camera body.

[0018] Preferably, as an improvement, protective shells are symmetrically arranged on the outer wall of the installation shell, and the protective shells wrap the connection part of the first transmission belt and the rotating shaft.

[0019] The beneficial effects are as follows: By the protective shell wrapping the connection part of the first transmission belt and the rotating shaft, external interference with the transmission of the first transmission belt and the rotating shaft is prevented.

[0020] Preferably, as an improvement, the first motor is set as a double-output shaft motor, and the first transmission belt is respectively sleeved on the output shafts at both ends of the first motor and the outer wall of the rotating shaft.

[0021] The beneficial effects are as follows: By setting the first motor as a double-output shaft motor, the rotation stability of the rotating shaft can be increased.

[0022] Preferably, as an improvement, the highest point of the moving block is higher than the first rotating rod.

[0023] The beneficial effects are as follows: When the moving block moves in a direction away from the first rotating rod, the first connecting rod can quickly descend, thereby better protecting the camera component. BRIEF DESCRIPTION OF THE DRAWINGS

The first transmission belt 8 is sleeved on the outer walls of the rotating shaft 5 and the output shaft of the first motor 7. Protective shells 28 are symmetrically arranged on the outer wall of the mounting shell 1, and the protective shells 28 wrap the connection part of the first transmission belt 8 and the rotating shaft 5. A camera component is arranged inside the mounting shell 1.

[0032] The camera component includes two groups of bases, as Figure 3As shown, each group of bases includes two mounting blocks 9. A first rotating rod 10 is rotatably installed between the two groups of bases. Symmetrically arranged on the outer wall of the first rotating rod 10 are first connecting rods 11. Rotatably installed at the opposite ends of the two first connecting rods 11 are second rotating rods 12. Fixedly installed at the mutually approaching ends of the two second rotating rods 12 are second connecting rods 13. Rotatably installed at the ends of the two second connecting rods 13 away from the second rotating rods 12 is a camera body 14. Fixedly installed at the mutually remote ends of the two first connecting rods 11 is a second motor 15. A second drive belt 16 is tensioned between the output shaft of the second motor 15 and the second rotating rod 12. Fixedly installed on the inner bottom of the installation shell 1 is a second controller 17. The second controller 17 is electrically connected to the acceleration sensor 3, and the second motor 15 is electrically connected to the second controller 17.

[0033] As Figure 3 shown, fixed to the inner wall of the installation shell 1 is a cylinder 18. Fixed to the output end of the cylinder 18 is a moving block 19. The top end of the moving block 19 is in contact with the two first connecting rods 11 respectively, and the top view of the moving block 19 is in a U shape. Symmetrically fixed to the inner bottom of the installation shell 1 are support bases 20. A placement groove is provided at the top end of the support base 20 for supporting the second connecting rod 13. Fixed to the opposite ends of the support base 20 is a third controller 21. The third controller 21 is electrically connected to the acceleration sensor 3, and the cylinder 18 is electrically connected to the third controller 21.

[0034] As Figure 3 shown, two first torsion springs 22 are sleeved on the outer wall of the first rotating rod 10, and the two first torsion springs 22 are respectively located between each group of bases. One end of the first torsion spring 22 is fixedly connected to the mounting block 9, and the other end is fixedly connected to the first connecting rod 11.

[0035] The highest point of the moving block 19 is higher than that of the first rotating rod 10.

[0036] The specific implementation process is as follows:

[0037] The staff first use bolts to fixedly install the connecting block 2 on the outer wall of the installation shell 1 on the vehicle, thus completing the fixation of the installation shell 1. When the device needs to be used, first start the first motor 7 to drive the first transmission belt 8 to rotate, thereby driving the rotating shaft 5 to rotate, so that the rotating plate 6 fixed on the outer wall of the rotating shaft 5 opens the installation shell 1. Subsequently, start the cylinder 18 to push the moving block 19 forward, so that the first connecting rod 11 rotates around the first rotating rod 10, and the rear end of the first connecting rod 11 is lifted, and the second connecting rod 13 is lifted by driving through the second rotating rod 12, so that the camera body 14 between the second connecting rods 13 is lifted. At this time, the first torsion spring 22 undergoes a torsional deformation. Then start the second motor 15 to drive the second transmission belt 16 to rotate the second rotating rod 12, so that the second connecting rod 13 is further raised, thereby further increasing the shooting height of the camera body 14, and the camera body 14 extends out of the installation shell 1 for recording;

[0038] In case of dangerous situations such as car accidents, the acceleration sensor 3 receives signals and transmits them to the first controller 4, the second controller 17, and the third controller 21, so that the first controller 4, the second controller 17, and the third controller 21 respectively and simultaneously start the first motor 7, the second motor 15, and the cylinder 18. Start the second motor 15 to drive the second transmission belt 16 to rotate, so that the second connecting rod 13 rotates downward, thereby driving the camera body 14 to retract into the installation shell 1. Start the cylinder 18 to make the moving block 19 move backward, so that the first connecting rod 11 rotates into the installation shell 1 under the action of the first torsion spring 22, so that the second connecting rod 13 further descends, thereby increasing the speed of retracting the camera body 14. At the same time, the first motor 7 drives the rotating shaft 5 to rotate through the first transmission belt 8, so that the rotating plate 6 fixedly connected to the outer wall of the rotating shaft 5 moves toward the opening direction of the installation shell 1 and rotates to completely cover the opening of the installation shell 1. At this time, the installation shell 1 and the rotating plate 6 wrap the camera body 14 inside, thereby protecting the camera body 14 and preventing the camera body 14 from being damaged and losing recorded data.

[0039] Embodiment 2

[0040] The principle of Embodiment 2 is substantially the same as that of Embodiment 1, the difference being that: as Figure 4As shown, a rotating block 23 is symmetrically fixedly installed on the outer wall of the camera body 14, and the two rotating blocks 23 are rotatably connected to the adjacent second connecting rods 13 respectively, and a second torsion spring 24 is symmetrically fixedly installed on the outer wall of the rotating block 23. The second torsion spring 24 is sleeved on the outer wall of the rotating block 23, and a disk 25 is fixedly installed on the end of the two second torsion springs 24 away from the camera body 14, and the disk 25 is slidably sleeved on the outer wall of the rotating block 23, and the disk 25 abuts against the second connecting rod 13. A plurality of protrusions 26 are provided at the ends of the two disks 25 away from each other, and the protrusions 26 are arranged in an arc shape, and grooves 27 matching the protrusions 26 are provided at the opposite ends of the two second connecting rods 13.

[0041] When the staff rotates the camera body 14, the second torsion spring 24 will undergo torsion deformation. When the torsion deformation of the second torsion spring 24 reaches a limit, the disk 25 is rotated by the second torsion spring 24. The rotating disk 25, under the action of the protrusion 26, will engage with the groove 27 of the second connecting rod 13, thereby quickly fixing the camera body 14 and playing the role of quickly adjusting the shooting angle of the camera body 14.

[0042] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
