Description

Technical Field

[0001] The present invention relates to the field of driving recorders, and in particular to a flameout power supply system and equipment for driving recorders. Background Art

[0002] As the number of cars continues to increase, car owners are paying more and more attention to vehicle safety. Traditional dashcams mainly record driving images while the vehicle is in motion, but their monitoring capabilities are often limited after the vehicle is turned off and parked. In order to make up for this shortcoming, dashcams with power supply functions after the engine is turned off have gradually appeared on the market. These devices can continue to work for a period of time after the vehicle is turned off, providing additional safety protection for car owners; However, after the engine is turned off, the camera of a traditional dash cam is usually kept on continuously, which not only accelerates battery consumption and shortens battery life, but also in most cases, the images recorded by the camera have no actual value, resulting in unnecessary waste of resources.

[0003] For example, the Chinese invention patent (application number: 201510643128.4) discloses a "power supply method and device for a driving recorder". Its specification discloses: the method includes: judging whether the vehicle has the start-stop function turned on; if so, after the vehicle stops, detecting whether the power supply of the driving recorder is the vehicle power supply; when the vehicle power supply is the power supply of the driving recorder, detecting whether the vehicle is triggered to start; if so, switching the power supply of the driving recorder from the vehicle power supply to the battery in the driving recorder. The embodiment of the present invention ensures the normal operation of the driving recorder when the vehicle is restarted, reducing the loss of monitoring video; the above patent can prove the defects of the prior art.

[0004] Therefore, we make improvements to this and propose a flameout power supply system and equipment for a driving recorder. Summary of the 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 should fall within the scope of protection of the present invention.

[0021] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] Example 1 Please refer to Figure 1 , a ignition-off power supply system for a driving recorder, wherein the power module of the driving recorder directly supplies power to the entire system from the vehicle power supply if the vehicle is in the starting state; if the vehicle is turned off, the power module switches to the backup power supply, and when the power is lower than a preset threshold, the power module sends a low-power reminder to the owner through a controller, suggesting that the owner charge the backup power supply as soon as possible; The collection module is responsible for capturing and recording information about the vehicle's external environment, including visual and auditory information. When the vehicle is turned off and the system is in monitoring mode, the collection module will continue to work to respond to possible security threats; The detection module sends a signal to the controller when the vehicle vibrates, thereby activating the collection module; The controller is responsible for processing the signals from each module, making decisions based on preset logic and algorithms, and then issuing corresponding commands to other modules; The reminder module is used to connect to the owner's mobile phone. When the vehicle is turned off and the collection module is triggered, the information is reminded to the owner's mobile phone; The control module controls the extension and rotation of the collection module to record the angle of the picture through the controller.

[0025] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the power module includes: Switch control unit, when the vehicle is turned off, switch the power supply of the collection module to the backup power supply; The backup power supply is used to provide power to the collection module by switching the control unit when the car is turned off. When the power is lower than the preset threshold, the backup power supply sends a low power reminder to the owner through the controller, reminding the owner to charge the backup power supply as soon as possible.

[0026] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, the collection module includes: The visual unit, when activated, captures the external image and stores the information in the storage unit. In standby mode, the collection module only maintains basic power management and communication functions, and the visual unit and the auditory unit are not activated to save power. The visual unit uses an image recognition algorithm to detect whether there is someone trying to break the window and enter the car in the image. If a potential threat is detected, the visual unit sends a signal to the control module through the controller to control the telescopic unit to quickly retract the collection module and turn off the recording function of the visual unit to protect the video data and save power at the same time. To identify potential security threats (such as someone trying to break into the car through the window), the following algorithms can be used: Edge detection algorithm: used to detect edge information in an image, which helps to identify the outline and shape of an object. For example, the Canny edge detection algorithm can be used; Object detection algorithm: used to identify specific objects (such as people, cars, etc.) in an image. You can use the YOLO (You Only Look Once) series of algorithms or the SSD (Single Shot MultiBox Detector) algorithm; The auditory unit is used to record audio information and store it in the storage unit, and to distinguish which side has the loudest sound while collecting audio, so as to locate the source of the attack, thereby rotating the visual unit through the controller and the control module, thereby changing the shooting angle of the recorded picture; The hearing unit adopts a multi-microphone array layout, which captures sound signals from different directions and converts them into electrical signals for transmission; the system integrates sound arrival time difference (TDOA) calculation and sound intensity analysis: Sound arrival time difference calculation: Utilize the limited propagation speed of sound waves to calculate the time difference between different microphones receiving sound signals and preliminarily determine the location of the sound source; Sound intensity analysis: Compare the sound signal strengths received by different microphones to further confirm the precise location of the sound source. Usually, the direction of the microphone with the highest sound intensity is the sound source. Combined with the fusion positioning algorithm, the final position of the sound source is determined through the optimization algorithm by comprehensively considering the time difference and intensity information; once the position is determined, the auditory unit immediately sends a signal to the steering unit through the controller, causing the visual unit to turn to the corresponding side for recording; The storage unit is used to store the information collected by the visual unit and the auditory unit; when the protection unit is activated, the video collected in this part is backed up to the device connected to the prompt module through the controller.

[0027] Further, such as Figure 3 and Figure 4 As shown, the control module includes: The telescopic unit sends a signal to the controller when the detection module detects that the vehicle is vibrated, and the controller causes the telescopic unit to extend the collection module; The steering unit uses the auditory unit to distinguish which side has the loudest sound, and then sends a control signal to the steering unit through the controller, so that the steering unit turns the visual unit to the corresponding side to record the picture; The protection unit, when the visual unit recognizes that someone wants to break the window to enter the car, the information is sent to the protection unit through the controller, and then the protection unit is activated. The protection unit informs the owner of the information through the controller and the prompt module. The protection unit causes the telescopic unit to retract the collecting module for protection, and turns off the detection vibration function of the detection module. The auditory unit collects external audio information and detects the sound volume. When the sound is in a relatively stable state for a long time, the collecting module is extended, and the steering unit is used to make the visual unit slowly look around and record the surrounding scenes, then the collecting module is retracted, the protection unit is turned off, and the detection vibration function of the detection module is turned on.

[0028] Example 2 The ignition-off power supply system of the driving recorder provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the reminder module includes: A reminder unit, used for collecting information sent by the controller and transmitting the information to the device connected to the device connection unit; The device connection unit is used to connect to the device used by the car owner and receive the information sent by the reminder unit, and remind the connected device of the information. When the information is the information for starting the collection module, a yellow reminder message is prompted on the screen of the connected device and a reminder sound is emitted; when the information is the information sent by the protection unit, a red reminder message is prompted on the screen of the connected device, and a continuous reminder sound is emitted for a certain period of time. During the prompt process, a close button and a view button are displayed on the screen. When the close button is selected, the reminder sound is turned off. When the view button is selected, the video collected by the collection module when the protection unit is activated is played on the screen of the car owner's device.

[0029] Further, such as Figure 3 As shown, the detection module includes: The vibration detection unit filters and identifies the vibration signal to distinguish between normal vehicle vibration and potential abnormal vibration (such as theft attempt); if it is identified as abnormal vibration, the detection module sends a trigger signal to the controller, starts the telescopic unit to extend the collection module to the outside, and records it through the collection module.

[0030] Example 3 The ignition-off power supply system of the driving recorder provided in Embodiment 1 or 2 is further optimized. Specifically, Figure 5 and Figure 6 As shown, a flameout power supply device for a driving recorder includes two installation boxes 1, wherein the installation box 1 is provided with a battery and a controller. When the vehicle is flameout, the power supply of a camera 5 is switched to the power supply inside the installation box 1 through the controller. A moving component 2 is provided inside the installation box 1, and an opening communicating with the inside of the installation box 1 is provided at the top of the installation box 1. A transmission component 3 is provided inside the opening, and a rotating component 4 is provided at the top of the transmission component 3. A camera 5 is provided at the front end of the rotating component 4. The camera 5 is electrically connected to the battery through the controller, and the battery provides power to the camera 5. The camera 5 records images. A vibration sensor is provided on the vehicle, and the vibration sensor is electrically connected to the controller. The two installation boxes 1 are installed upside down at the top of the interior of the vehicle, with the opening of the installation box 1 facing downward. The two installation boxes 1 are symmetrically arranged and located at the front and rear respectively, so that the two cameras 5 can respectively shoot the front and rear perspectives, thereby making the shooting perspective more comprehensive. At the same time, the car windows are used to protect the internal cameras 5 to prevent the cameras 5 from being damaged during the recording process. A protective component 6 is provided at the rear end of the rotating component 4, and a lighting lamp 7 is provided inside the protective component 6. A photoresistor is provided at the front end of the camera 5. The lighting lamp 7 is electrically connected to the battery inside the installation box 1 through the photoresistor. Under light, the electrons of the semiconductor material will be excited, so that the resistance value will decrease; in the absence of light or weak light, the resistance value will increase, and the lighting lamp 7 will provide lighting for the camera 5.

[0031] Further, such as Figure 5 and Figure 6As shown, the moving assembly 2 includes a No. 1 motor 21 fixed to the rear end of the installation box 1, and a moving platform 23 slidably connected to the inside of the installation box 1 is provided in front of the No. 1 motor 21. The No. 1 motor 21 is electrically connected to the controller. When the vehicle is in an off state, the vehicle is hit, knocked or vibrated, which will be detected by the vibration sensor, thereby controlling the No. 1 motor 21 to start and rotate the output end. Therefore, when some conditions occur in the vehicle, the camera 5 will be extended to the outside through the transmission assembly 3 and the rotating assembly 4 to record the external picture, avoiding unnecessary power consumption. A threaded rod 22 is fixedly provided at the output end of the No. 1 motor 21. When the No. 1 motor 21 is started, the threaded rod 22 is driven to rotate. The end of the threaded rod 22 passes through the moving platform 23 and is rotatably connected to the front end of the installation box 1. The threaded rod 22 is threadedly connected to the moving platform 23. When the threaded rod 22 rotates, the moving platform 23 is driven to move inside the installation box 1 through the thread. The transmission assembly 3 includes two mounting plates 31 respectively hinged to the front and rear of the top end of the moving platform 23, the mounting plates 31 are used to connect with the rotating assembly 4, one side of the mounting plate 31 is provided with a slide groove 32 connected to the other side of the mounting plate 31, and the interior of the slide groove 32 is provided with a support rod 33 fixedly connected to the mounting box 1. When the moving platform 23 moves forward and backward, the mounting plate 31 is driven to move backward. Since the support rod 33 slides inside the slide groove 32, the two mounting plates 31 are hinged to tilt and fold forward, thereby driving the rotating assembly 4 to retract downward.

[0032] Further, such as Figure 6 and Figure 7 As shown, the rotating assembly 4 includes a connecting box 41 hinged at the top of the two slide slots 32, a No. 1 gear 42 is provided for internal rotation of the connecting box 41, and a No. 2 gear 43 is meshed at the rear end of the No. 1 gear 42 and connected to the internal rotation of the connecting box 41. When the No. 2 gear 43 rotates, the No. 1 gear 42 is driven to rotate. The camera 5 is located at the top of the connecting box 41, and a connecting seat 45 is fixedly provided at the top of the No. 1 gear 42. The connecting seat 45 passes through the connecting box 41 and is fixedly connected to the bottom end of the camera 5. When the No. 1 gear 42 rotates, the camera 5 is driven to rotate through the connecting seat 45, thereby changing the shooting angle of the camera 5. A No. 2 motor 44 is provided at the rear end of the camera 5 and is fixedly connected to the connecting box 41. The No. 2 motor 44 drives the No. 2 gear 43 to rotate, and the output end of the No. 2 motor 44 passes through the connecting box 41 and is fixedly connected to the No. 2 gear 43.

[0033] Further, such as Figure 5 and Figure 8As shown, the protective assembly 6 includes a fixing plate 64 fixed to the rear of the top of the connecting box 41, and the top of the mounting box 1 is hingedly provided with a hinged plate 63 located behind the opening. When the connecting box 41 is retracted downward, the hinged plate 63 is hingedly flipped forward to cover the opening. The top of the hinged plate 63 is provided with a protective plate 61 hinged to the upper rear end of the fixing plate 64, and the front of the top of the opening is covered by the protective plate 61 to protect the camera 5 inside. A connecting groove 62 is provided at the bottom end of the protective plate 61, and the hinged plate 63 is slidably connected to the inside of the connecting groove 62. The sliding connection enables the protective plate 61 and the hinged plate 63 to have a telescopic function to cooperate with the change in the length of the protective assembly 6 when the connecting box 41 moves up and down. The lighting lamp 7 is arranged above the front end of the protective plate 61. When the connecting box 41 is extended, the lighting lamp 7 is exposed through the protective plate 61, so that the lighting lamp 7 can better provide lighting for the camera 5. When the connection box 41 is retracted, the protection plate 61 is covered again, so that the illuminating lamp 7 faces the inside of the opening, thereby protecting the illuminating lamp 7 inside.

[0034] The use process of the ignition-off power supply system and device of the driving recorder provided by the present invention is as follows: When the vehicle is hit or vibrated, the vibration sensor detects it and then controls the No. 1 motor 21 to start and drive the threaded rod 22 to rotate. The threaded rod 22 drives the moving platform 23 to move forward, so that the mounting plate 31 is guided by the support rod 33 inside the slide groove 32 to stand up the mounting plate 31, thereby driving the rotating component 4 to rise, and then driving the protective plate 61 to stand up through the hinge plate 63, and recording the external picture through the camera 5, and starting the No. 2 motor 44 to drive the camera 5 to rotate through the No. 2 gear 43 and the No. 1 gear 42, so as to adjust the shooting angle; when the brightness of the external environment is poor, the lighting 7 is used to provide brightness illumination for the camera 5.
