Description

Technical Field

[0001] The invention belongs to the technical field of vehicle driving recorders, and in particular relates to a hidden vehicle driving recorder and a power supply method. Background Art

[0002] A hidden dash cam is a driving recorder integrated into the original parts of the vehicle (such as the rain sensor housing). Its main features are concealed appearance, difficulty in being detected after installation, and integration with the overall style of the vehicle. Hidden dash cams are usually installed near the rearview mirror or rain sensor inside the vehicle. Their concealed appearance will not affect the overall beauty of the vehicle's interior. Due to their concealment, hidden dash cams are not easily discovered by outsiders, thereby reducing the risk of theft. At the same time, they can record the entire video of the vehicle's driving process, providing strong evidence for the determination of accident responsibility.

[0003] Problems with existing technologies: The defects of driving recorders are mainly reflected in the following aspects: Heating problem: Since the dashcam usually needs to work continuously, it generates a lot of heat. Long-term high-temperature operation may accelerate the aging of the internal components of the device and shorten its service life. Safety issues: When a vehicle windshield is severely shattered in a traffic accident, the shattered windshield is likely to damage the dashcam attached to it, causing the dashcam to be unusable; The problem of cumbersome evidence collection: Most dashcams will enter the recording state after the vehicle is started. When a traffic accident occurs, although the corresponding APP of some dashcams can lock the current video information, due to the long video length, it still takes a lot of time to obtain and intercept the video information in the important time period as evidence.

DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] like Figure 1-Figure 9As shown, a hidden driving recorder includes an original base plate 1 and a rain sensor housing 3. The original base plate 1 is installed inside the vehicle at the position of the head rearview mirror. The rain sensor housing 3 and the original base plate 1 form a detachable card and assembly. A cabin 301 is integrally provided in the middle of the inclined bottom end of the rain sensor housing 3, and a casing 4 for completing driving recording is detachably assembled on the inner side of the cabin 301. Inertial wind turbines 5 for heat dissipation are fixedly installed on both sides of the interior of the rain sensor housing 3, and a main control chip 6 is installed inside the casing 4.

[0023] See attached Figure 1-Figure 2 , Figure 5 A sensor 2 is fixedly installed in the middle of the original bottom plate 1, and an interface for powering the sensor 2 is provided on one side of the surface of the original bottom plate 1. The housing 4 is electrically connected to the interface and the power line in the vehicle through a low-voltage tapping line 404, and the sensor 2 and the housing 4 are powered by a power battery or a storage battery in the vehicle. A lens 401 is embedded at one end of the housing 4, a storage card 402 is detachably installed on one side of the housing 4, and a button 403 is fixedly provided on the other side of the housing 4.

[0024] According to the above structure, the rain sensor housing 3 is snap-fitted and assembled with the original bottom plate 1 in the car, and then the casing 4 is assembled with the rain sensor housing 3, so that the installation of the hidden driving recorder can be completed. The low-voltage tapping line 404 is used to connect the power supply to the recorder, and the lens 401 completes the video shooting. The storage card 402 in the card slot is used to store video information. The above descriptions are all prior art and will not be repeated here.

[0025] Embodiment 1: See attached Figure 1-Figure 2 , Figure 5 , single arc-edge protrusions 405 are fixedly provided on both side walls of the housing 4.

[0026] See attached Figure 5-Figure 6 The inner walls on both sides of the cabin 301 are penetrated with sliding grooves 305, and the single arc-edge protrusions 405 slide through the corresponding sliding grooves 305, the bottoms on both sides of the cabin 301 are provided with straight rail grooves 306, and the straight rail grooves 306 are slidably assembled with sliders 307, the sliders 307 are elastically and telescopically assembled with card plates 308, and the top of the card plate 308 is provided with a card slot for the single arc-edge protrusion 405 to be inserted, and a spring 309 is connected between the slider 307 and the inner wall of the cabin 301, and the spring 309 is in a stretched state.

[0027] See attached Figure 5-Figure 7The side walls on both sides of the interior of the cabin 301 are slidably assembled with wedge-shaped blocks 310 for temporarily fixing the slider 307, and the side walls of the cabin 301 are rotatably installed with a pry bar 311 located inside the rain sensor housing 3, one end of the pry bar 311 is connected to the corresponding wedge-shaped block 310, and a spring 2 312 is connected between the other end of the pry bar 311 and the side wall of the cabin 301, and the side walls of the cabin 301 are horizontally fixedly installed with a guide rod 313 located inside the rain sensor housing 3, and a counterweight slide 314 is slidably assembled on the outer surface of the guide rod 313, one end of the counterweight slide 314 is in contact with one end of the pry bar 311, and the end of the pry bar 311 close to the counterweight slide 314 is provided with a resistance protrusion 315 for temporarily resisting the counterweight slide 314.

[0028] According to the above structure, when a violent collision occurs at the front of the vehicle, the speed of the high-speed vehicle suddenly decreases. Under the action of inertia, the counterweight slider 314 moves and disengages from the resistance protrusion 315, and it directly squeezes the pry bar 311. The pry bar 311 directly rotates after being subjected to this stress, and its other end will directly pry the wedge block 310. The wedge block 310 will eventually disengage from the slider 307, and the slider 307 will immediately be released from the fixed state. Then, under the pull of the spring 1 309, the slider 307 will carry the housing 4 and move quickly away from the front of the vehicle, ensuring that the housing 4 is as far away from the accident location as possible, avoiding damage to the housing 4 by the broken windshield, and protecting the integrity of the recorder equipment as much as possible, thereby reducing the possibility of accidental loss of important video information.

[0029] The working principle of the present invention is as follows: after the rain sensor housing 3 is installed, the housing 4 is aligned with the inner side of the cabin 301, the single arc edge protrusion 405 is aligned with the sliding groove 305, and the housing 4 is slid and pushed to the limit position. During the process, the single arc edge protrusion 405 will be squeezed with the card plate 308, and the card plate 308 will first be retracted into the slider 307 until the single arc edge protrusion 405 is snapped into the corresponding card groove. This installation method is different from the traditional rain sensor housing 3 and housing 4 integrated structure. The difficulty of the installation operation is simplified through the step-by-step installation process, and at the same time, the accidental extrusion damage to the instrument body during installation is reduced; When a severe collision occurs at the front of the vehicle, the speed of the high-speed vehicle decreases suddenly. Under the action of inertia, the weight slider 314 moves and separates from the resistance protrusion 315, and directly squeezes the pry bar 311. The pry bar 311 rotates directly after being subjected to this stress, and the other end thereof directly pries the wedge block 310. The wedge block 310 eventually separates from the slider 307, and the slider 307 then leaves the fixed state. Then, under the pull of the spring 1 309, the slider 307 quickly moves away from the front of the vehicle with the housing 4. After an accident, when the driving recorder is not damaged and can be restored to use, it is only necessary to push the housing 4 again, and the housing 4 will carry the slider 307 to slide, and the slider 307 and the wedge-shaped block 310 will be squeezed until the slider 307 is re-stuck, and then it can be restored to use.

[0030] Embodiment 2: See attached Figure 2-Figure 3 Both side walls of the rain sensor housing 3 are provided with heat dissipation holes 302, a protective cover 303 is detachably assembled in the middle of the inclined top of the rain sensor housing 3, a fan housing 304 is fixedly installed on the inner wall of the rain sensor housing 3 and at the position of the heat dissipation holes 302, and fan blades are rotatably installed at both ends of the inside of the fan housing 304.

[0031] See attached Figure 3-Figure 4 The inertial wind turbine 5 includes a transmission shell 501, and the outer wall of one end of the transmission shell 501 is rotatably assembled with a wall rod 502, and a counterweight circular plate 504 is fixedly installed at the end of the wall rod 502 away from the center of rotation, and the outer wall of the transmission shell 501 is fixedly provided with a limit stopper 503 for limiting the rotation range of the wall rod 502, and the interior of one end of the transmission shell 501 is fixedly installed with a gear 1 506 fixedly connected to the wall rod 502, and the counterweight circular plate 504 utilizes the inertia of the vehicle during driving to drive the corresponding gear 1 506 to rotate, and a gear 2 507 meshing with the gear 1 506 is rotatably installed at one end of the interior of the transmission shell 501, and a gear 3 508 is coaxially fixedly assembled on one side of the gear 2 507.

[0032] See attached Figure 3-Figure 4 A movable gear 509 is movably assembled in the middle of the transmission shell 501, and separation guide grooves 505 for guiding the movement of the movable gear 509 are penetrated on both sides of the middle part of the transmission shell 501, and the movable gear 509 is detachably meshed with gear three 508. A flywheel 510 and a counterweight rotor 512 are rotatably assembled on the outer wall of the other end of the transmission shell 501, and the flywheel 510 axle extends to one end of the transmission shell 501 and is fixedly assembled with gear four 511, and gear four 511 is meshed with the movable gear 509, and the counterweight rotor 512 axle extends to one end of the flywheel 510 and is fixedly assembled with gear five 513, and gear five 513 is meshed with the flywheel 510, and the counterweight rotor 512 is connected to the fan blades inside the adjacent fan shell 304 through a sleeved belt 514.

[0033] According to the above structure, when the vehicle decelerates or accelerates, the counterweight circular plate 504 at the corresponding position will drive the corresponding gear 1 506 to rotate due to inertia, and the counterweight rotor 512 is finally driven to rotate through the meshing of gear 1 506 and gear 2 507, the meshing of gear 3 508 and movable gear 509, the meshing of movable gear 509 and gear 4 511, and the meshing of flywheel 510 and gear 5 513. After the speed adjustment of the gear set, the speed and number of revolutions of the counterweight rotor 512 are increased, and with the help of inertia, the counterweight rotor 512 will continue for a period of time. During the high-speed operation, the axle of the movable gear 509 moves along the separation guide groove 505 and separates from the gear three 508. The movable gear 509 is designed to ensure that the counterweight rotor 512 only rotates in one direction. Finally, the counterweight rotor 512 drives the fan blades inside the fan housing 304 to rotate at a high speed through the belt 514, thereby completing the cooling of the driving recorder. This cooling process does not require the installation of additional electrical components, and can be completed by utilizing the speed change process during the vehicle's driving process and inertia, without generating additional heat and power consumption.

[0034] The working principle of the present invention is as follows: when the vehicle decelerates or accelerates, the counterweight circular plate 504 at the corresponding position will drive the corresponding gear 1 506 to rotate due to inertia, and through the meshing of gear 1 506 and gear 2 507, the meshing of gear 3 508 and movable gear 509, the meshing of movable gear 509 and gear 4 511, and the meshing of flywheel 510 and gear 5 513, the counterweight rotor 512 is finally driven to rotate. After the speed regulation of the gear set, the speed and number of revolutions of the counterweight rotor 512 are improved. Also with the help of inertia, the counterweight rotor 512 will continue to operate at a high speed for a period of time. During its rotation, the axle of the movable gear 509 will move along the separation guide groove 505 and separate from the gear 3 508. The design of this movable gear 509 is used to ensure that the counterweight rotor 512 only rotates in one direction. Finally, the counterweight rotor 512 drives the fan blades inside the fan housing 304 to rotate at a high speed through the belt 514, thereby completing the cooling of the driving recorder.

[0035] Embodiment three: See attached Figure 8-Figure 9The main control chip 6 is internally provided with a sensor unit 601, an image recognition unit 602, a camera unit 603, a data processing unit 604 and a storage unit 605.

The storage unit 605 is used for storage and memory optimization, and the communication unit 606 is used for data transmission.

[0036] According to the above structure, refer to the attached Fig. 9 The driving recorder executes the camera command through the camera unit 603 when driving. When a driving accident occurs, the sensor unit 601 determines that the vehicle is hit, braked suddenly, the distance is too short, the lane of the front vehicle is deviated, and there are people in the front vehicle through the detection information of various sensors and the image recognition unit 602 through the image recognition information. The video information in the current shooting work will be processed by the data processing unit 604, and the video information will be saved as important video information; In the processing work of the data processing unit 604, the specific time T of the accident is first determined by the image acquisition time point determination unit 610, and within the total time length of the current driving record video, the video interception unit 611 intercepts a video segment of t1 time before time T and t2 time after time T, and the to-be-determined video generation unit 613 extracts the video segment and uses it as a separate video. The video time period adjustment unit 612 is given the ability to adjust the t1 time length and t2 time length data. When the APP authorizer logs in to the corresponding APP, the values ​​of t1 time length and t2 time length can be directly adjusted in the above-mentioned generated separate video to directly obtain the video information in the corresponding time period. If no adjustment is required, the authorizer can also directly use the separate video as important evidence information; In the above process, when a vehicle collides, brakes suddenly, the distance between vehicles is too short, the lane of the vehicle in front is deviated, or there is a person in the vehicle in front, the video information of the current shooting work is first saved as the key object, and then the video clips in the important time period before and after the accident are extracted from the total video. When the authorized person opens the corresponding APP, he can directly obtain the video information in the important time period, and can also obtain it by adjusting the before and after time. This greatly facilitates the process of video evidence collection, facilitates the operation of evidence collection, and shortens the time of evidence collection.

Within the total duration, the video capture unit 611 captures a video segment of t1 time before moment T and t2 time after moment T, and the video generation unit 613 extracts the video segment as a separate video. The video time period adjustment unit 612 is given the ability to adjust the t1 and t2 duration data.

In parking mode, the system will automatically determine whether to use the battery first based on the current power level and vehicle status. If the battery is sufficient and meets certain conditions (such as the vehicle is stationary and there is no external charging), the system will give priority to using the battery to power the parking mode.
