[Document No.] g07c5 / 08gk205486340sq201620047488 0【Publication date: August 17, 2016 [application date] January 19, 2016 [inventor] Li Jianneng [applicant] Shenzhen biteye Technology Co., Ltd The utility model discloses a tachograph and a vehicle containing the tachograph. The tachograph includes a power supply and a recorder body connected with the power supply. The recorder body includes: a rotating upper base, a rotating base which is rotationally connected with the rotating upper base, a shell connected with the rotating base, a first camera and a second camera installed on the shell, a first control PCB board assembly contained in the shell and a sensor lens. The power supply has a rechargeable battery. By setting the first camera and the second camera, the driving recorder of the utility model increases the shooting angle, expands the video protection range, and makes the image recording more comprehensive. By setting rechargeable battery, PCB board components and sensor lens, the dash cam can also start the video recording function to record the scene images of relevant accidents when the car is in the state of parking and flameout. The utility model relates to a vehicle auxiliary device, in particular to a tachograph and a vehicle containing the tachograph. Background technologyWith the popularity of cars and the construction of roads, inter city economic exchanges become more frequent, and driving has become a very common way of travel. Usually, in order to avoid the vehicle collision accident can not restore the truth and clarify the responsibility, people often install the dash cam at the front windshield of the vehicle. By means of this recorder, the images of vehicles in motion can be continuously photographed, so as to provide complete driving conditions in case of accidents, which can be used as evidence to restore the truth of the accident and clarify the responsibility. [0003] the operation mode of the existing tachograph is that the power is supplied to the tachograph when the vehicle is started. The dash cam stores the images or pictures taken by it as more than one image file at a fixed time interval, and writes them into the memory card of the dash cam. When the memory card is full, delete the earliest stored video files for repeated recording. [0004] when the vehicle is in the flameout state and there is no external power supply to the tachograph, the tachograph is in the shutdown state. If the vehicle is hit by external force or other vehicles, the image of collision or collision accident cannot be taken. If the driver of the hit vehicle is not at the scene, it is more difficult to clarify the accident responsibility. [0005] therefore, there are still deficiencies in the protection of existing tachographs for collision accidents after the vehicle is turned off or the tachograph is turned off. [0006] the traditional tachograph has the following defects: [0007] 1. The shooting angle is not wide enough, generally no more than 150 degrees. It can only record the image in front of the two a pillars of the car, but for the line with side impactThere is nothing to do. [0008] 2. It only has the function of recording the driving state, and can only record the driving state in recent hours. When a driving accident occurs, the driving data recorder can't store the driving state in time. If the driver or on-site personnel do not store it in time after the accident, the driving status may be deleted or covered. [0009] 3. It is impossible to record the collision image in parking state. If the vehicle is parked on the roadside and is hit by other external forces or other vehicles, the relevant images cannot be recorded. [0010] 4. With single function, it can only record driving images, which can be used as the basis for clarifying the responsibilities of both parties. [content of utility model] [0011] the purpose of the utility model is to overcome the shortcomings of the prior art, and provide a vehicle recorder with dual cameras and collision induction recording function. [0012] the purpose of the utility model is realized through the following technical scheme: [0013] a vehicle traveling data recorder, including a power supply and a recorder body connected with the power supply.

[0021] as a preferred scheme of the utility model, the power supply also includes a front cover and a back cover, and the front cover and the back cover are connected by a fixed nut and a fixed clip ring. [0022] as a preferred scheme of the utility model, the plug-in joint comprises a power supply positive contact piece, a fuse, a power negative contact piece and a compression spring which are connected in turn. [0023] a vehicle on which a tachograph with the above functional features is installed. [0024] compared with the prior art, the utility model has the following advantages: [0025] 1.

The tachograph 1 of the utility model can also be started when the vehicle is stopped and flameout by setting a rechargeable battery 110 on the power supply 100. [0037] in case of collision when the vehicle is stopped and flameout, the collision signal is received through the sensor lens 270 on the recorder body 200, and the power is supplied by the rechargeable battery 110, and the recording function of the recorder body 200 is activated, so that the first camera 240 and the second camera 250 installed on the housing 230 can shoot and record the image at that time. [0038] by setting the first camera 240 and the second camera 250, the driving recorder 10 of the utility model expands the recording angle range of the recorder body 200, so as to not only record the image in front, but also record the images on the left and right sides. [0039] due to the limitation of the angle of a single camera, the conventional tachograph can only capture a 150 degree image at most, but not the side image. The utility model can shoot the side image by setting a combination of the first camera 240 and the second camera 250, so that the side image can be shot and the whole driving record can be obtained The process is more comprehensive and the car can be better protected.

[background technology] [0002] with the development of urbanization and industrialization, people have become more and more dependent on the means of transportation, and drivers pay more and more attention to the protection of their own life and property. In addition to considering the performance and riding comfort of vehicles, they will also test whether the cars they want to buy provide enough safety protection devices or auxiliary devices. In this trend, automobile manufacturers or vehicle equipmentIn order to improve the safety of driving, designers have all racked their brains to develop various safety protection devices or auxiliary devices. However, there are still some problems to be solved in these safety protection devices or auxiliary devices. For example, when drivers change lanes or turn, they mostly use the rear-view mirror to judge whether there is an object. However, most of the rear-view mirrors have blind spots. Therefore, some vehicles are also equipped with detection devices for driving blind spots to improve driving safety 。 In the prior art, a driving dead angle detection system is disclosed. Several radars are installed on both sides of the vehicle to detect the objects in the dead corner area. However, the detection system can only provide local images for the driver's reference, and can not provide a complete panoramic image. At present, there are many GPS positioning systems that can be used by the driver to provide the current positioning information of the vehicle for the driver's reference, but these GPS positioning systems do not have the function of recording the driving path at any time. [0003] However, the above-mentioned devices operate independently. If consumers need a more complete driving auxiliary system, they need to install auxiliary devices with different functions, which is quite time-consuming and time-consuming. In case of an accident, only the data can be extracted from the above devices for analysis, which can not provide a complete and detailed analysis and restore the scene situation. Of course, the industry has also introduced traffic recording devices that can restore the scene, but most of these devices are wired connections. The wired connection inside or outside the vehicle undoubtedly brings disadvantages to the installation and the visual angle and beauty after installation.
