DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0037] The embodiment of the present invention provides a driving recorder, such as Figure 1-9 As shown, it includes a detachable shell 1, and a mounting bracket 3 capable of adjusting the mounting angle is installed on the upper end of the shell 1. A camera assembly 2, a main control board 12, a ventilation mechanism 6 and a temperature sensor 14 are arranged inside the shell 1. One end of the camera assembly 2 is installed on one side of the shell 1 through a focal length fine-tuning mechanism 5, and a through hole is opened on one side of the shell 1 for the other end of the camera assembly 2 to pass through. The ventilation mechanism 6 is installed on the other side of the shell 1, and one end of the ventilation mechanism 6 is electrically connected to a controller 10, and one end of the controller 10 is connected to a battery board 11. The ventilation mechanism 6 ventilates cold air or hot air according to the temperature value sensed by the temperature sensor 14, and the temperature sensor 14 is electrically connected to the controller 10. The main control board 12 is installed between the ventilation mechanism 6 and the camera assembly 2 through a supporting mechanism 9.

[0038] The battery panel 11 is used to power the temperature sensor 14 and the ventilation mechanism 6. The temperature sensor 14 senses the temperature value inside the housing 1 in real time, and transmits the sensed temperature value to the controller 10. The controller 10 controls the ventilation mechanism 6 to blow cold air or hot air according to the actual temperature value, so that the internal temperature of the housing 1 is maintained in a normal working range, that is, when the temperature is extremely low, hot air is passed through the inside of the housing 1 to heat the inside of the housing 1. When the temperature is extremely hot, cold air is passed through the inside of the housing 1 to cool the inside of the housing 1, so that the temperature inside the housing 1 is maintained within the normal room temperature range, thereby ensuring that the driving recorder can work normally in extremely hot or extremely cold environments.

[0039] After receiving the temperature value sensed by the temperature sensor 14, the controller 10 performs temperature value analysis and calculation processing, and controls the ventilation mechanism 6 to blow cold air or hot air according to the results of the analysis and calculation. The specific calculation process is as follows:

[0040] S1. Set the target temperature T0 to 10°C-35°C, and calculate the error An between the current temperature Ti and the target temperature T0. The error An calculation formula is: An=T0-Ti;

[0041] S2, calculate the output signal P of the controller out , the calculation formula is as follows:

[0042] P out =Kp*An+Ki*A2+Kd*A3,

[0043]

[0044] A2=A n-1 +A n-2 +……,

[0045]

[0046] A3=A n -A n-1 ,

[0047] Kd=Ki+A n *Δt,

[0048] Among them, Kp is the proportional coefficient, Ki is the integration time, Kd is the differential time, An is the error, A2 is the cumulative sum of historical errors, A3 is the difference between the current error and the previous error, and Δt is the sampling time interval;

[0049] S3, according to the output signal P of the controller 10 out Adjust the working power P of the ventilation mechanism 6 so that the temperature gradually approaches the target temperature T0. There are two situations:

[0050] S31. When the temperature value T1 sensed by the temperature sensor 14 is less than 10°C, An uses the minimum value of the target temperature T0 minus T1. If the value of An is between 0 and 20, the ventilation mechanism 6 needs to blow hot air, and the power is:

[0051] P=U 加热线圈 *I 加热线圈 +P out ;

[0052] S32. When the temperature value T1 sensed by the temperature sensor 14 is greater than 35°C, An uses the maximum value of the target temperature T0 minus T1. If the value of An is between -10 and 0, the ventilation mechanism 6 blows cold air with a power of:

[0053] P=m*U 制冷片 *I 制冷片 +P out , where m is the number of cooling plates 7 used.

[0054] like Figure 4 and Figure 6 As shown, the shell 1 includes a front shell 102 and a rear shell 101, the mounting bracket 3 is mounted on the upper end of the rear shell 101, the front shell 102 and the rear shell 101 are detachably connected via a snap-fit ​​mechanism, the camera assembly 2 and the focus fine-tuning mechanism 5 are located inside the front shell 102, the ventilation mechanism 6, the battery plate 11, the temperature sensor 14 and the controller 10 are all located inside the rear shell 101, and heat dissipation holes 4 are provided on opposite sides of the front shell 102. Through the setting of the snap-fit ​​mechanism, the front shell 102 and the rear shell 101 are detachably arranged, which is convenient for disassembling the shell 1 to install and maintain the electronic components inside it.

[0055] The clamping mechanism includes a protrusion 103 for fixing the upper and lower ends of the front shell 102, a T-block 104 is arranged on the lower surface of the protrusion 103, and a notch 105 for the protrusion 103 to enter is arranged at one end of the rear shell 101 close to the front shell 102, and a slot 106 for the T-block 104 to slide and insert is opened on one side of the notch 105. When the front shell 102 and the rear shell 101 are installed, one end of the T-block 104 is inserted from one end of the slot 106, and the front shell 102 is moved to align the front shell 102 with the rear shell 101, and the front shell 102 and the rear shell 101 are connected together, thereby improving the convenience of installing the front shell 102 and the rear shell 101.

[0056] like Figure 2As shown, the mounting bracket 3 includes two support plates 31 fixed to the upper end of the rear shell 101 and a protrusion 33 located between the two support plates 31, a suction cup 32 is fixed to the upper end of the protrusion 33, the protrusion 33 is rotatably connected to the support plate 31 by a pin shaft 35, and limiting components 34 for adjusting the rear limit of the inclination angle of the suction cup 32 are installed on the opposite sides of the protrusion 33, a plurality of limiting holes 36 are opened on the opposite side of the support plate 31, and the plurality of limiting holes 36 are arranged in a circular array with the center of the pin shaft 35 as the axis, and the limiting component 34 is located inside one of the limiting holes 36, and the suction cup 32 is manually moved to rotate around the pin shaft 35 to adjust the inclination angle of the suction cup 32, so that the suction cup 32 can be suitable for installation in different positions and can also be suitable for installation on different vehicle models, thereby improving the versatility of the driving recorder.

[0057] like Figure 3 As shown, the limit assembly 34 includes a limit column 341 with an arc-shaped end, and a compression spring 343 is fixed to the other end of the limit column 341. A mounting hole 342 for mounting the compression spring 343 and the other end of the limit column 341 is provided on one side of the protrusion 33, and a fixing hole 37 for mounting the pin shaft 35 is also provided on the protrusion 33. When the suction cup 32 is pried open, the limit column 341 is manually provided with a moving force so that the limit column 341 uses its arc surface to move one end of the limit column 341 out of one limit hole 36 and into the inside of the next limit hole 36. At the same time, the rebound force of the compression spring 343 is used to make the limit column 341 jam when entering another limit hole 36 from one limit hole 36. When the suction cup 32 is not subjected to external force, the limit column 341 is located inside the limit hole 36 to limit the position of the suction cup 32, thereby facilitating the adjustment of the tilt angle of the driving recorder according to actual usage requirements.

[0058] The camera assembly 2 is slidably mounted on the front shell 102. The camera assembly 2 can take photos or videos of the front of the vehicle while the vehicle is driving. The camera assembly 2 uses the existing technology in this field (such as the patent document application number 202211137524, which discloses a driving recorder and a control system for the driving recorder, and the camera device disclosed therein), so it will not be described in detail here.

[0059] like Figure 4 and Figure 5As shown, the focus fine-tuning mechanism 5 includes a folded edge 51 fixed to one end of the camera assembly 2 and a connecting plate 57 fixed to the inside of the front shell 102. The front shell 102 is provided with a moving hole for the other end of the camera assembly 2 to move. A toothed plate 53 is fixed to one side of the folded edge 51. The toothed plate 53 is slidably connected to the front shell 102 through a connecting mechanism, and there is a gap between the toothed plate 53 and the inner wall of the front shell 102. A rotating shaft 56 is rotatably installed on the connecting plate 57. A first motor 58 is installed at one end of the rotating shaft 56, and a gear 55 is installed at the other end of the rotating shaft 56. The gear 55 is meshed with the toothed plate 53. The other side of the folded edge 51 is connected to the inside of the front shell 102 through a telescopic rod 52. The rotating shaft 56 is driven to rotate by the first motor 58, so that the rotating shaft 56 drives the gear 55 to move on the toothed plate 53 to adjust the position of the toothed plate 53 on the connecting mechanism, thereby adjusting the length of the camera assembly 2 lens extending out of the front shell 102 to achieve the purpose of adjusting the focal length.

[0060] The connecting mechanism includes a fixed plate 54 fixed inside the front shell 102, and a sliding groove for the tooth plate 53 to slide is opened on the fixed plate 54. A stopper 59 is fixed to the end of the tooth plate 53 away from the folded edge 51. The setting of the stopper 59 can effectively prevent the tooth plate 53 from moving excessively. The fixed plate 54 provides a certain supporting force for the tooth plate 53, so that the camera assembly 2 can move smoothly.

[0061] like Figures 6 to 9As shown, the ventilation mechanism 6 includes a support cover 65 and a rotating shaft 62 installed in the middle of the support cover 65, a fan 61 is installed at one end of the rotating shaft 62, and a second motor 63 is installed at the other end of the rotating shaft 62. The base of the second motor 63 is installed on the inner wall of the rear shell 101, and an energy transfer component is arranged inside the support cover 65 on one side of which the rotating shaft 62 is installed. Refrigeration plates 7 are installed on the outer walls around the support cover 65, and an annular heating coil 8 is installed inside the support cover 65, and the heating coil 8 is located between the fan 61 and the energy transfer component. The temperature inside the housing 1 is determined by the average temperature of the electronic components inside the housing 1 when they are working normally, which is plus or minus 5°C. When the temperature inside the housing 1 is lower than the standard range, the controller 10 controls The heating coil 8 is heated to heat the energy transfer component, and the heating temperature does not exceed 35°C, because when the temperature exceeds 35°C, the semiconductor components inside the shell 1 may break down. At the same time, the second motor 63 is started, so that the fan 61 is driven to rotate by the second motor 63, and the energy transfer component is located at the air inlet end of the fan 61, so that the fan 61 fans out hot air to heat the inside of the shell 1 so that the electronic components inside the shell 1 can work normally. When the temperature inside the shell 1 is higher than the standard range, the controller 10 controls the refrigeration plate 7 to cool the energy transfer component to a low temperature. At the same time, the second motor 63 drives the fan 61 to rotate so that the fan 61 can fan out cold air, and the cold air is used to cool the inside of the shell 1 to ensure the normal operation of the electronic components inside the shell 1.

[0062] The energy transfer component includes a storage cavity located inside the support cover 65, and the interior of the storage cavity is filled with gel 64. The support cover 65 is cooled or heated by the refrigeration sheet 7 or the heating coil 8, and the heat is transferred to the gel 64 by the heat transfer effect, so that the gel 64 is in a cooled or warm state. Since the gel 64 is located at the air inlet end of the fan 61, the fan 61 can fan out cold air or hot air according to actual environmental requirements to ensure the stability of the driving recorder in extreme environments.

[0063] like Figure 6 As shown, the support mechanism 9 includes a plurality of cylinders and a stud fixed at one end of the cylinder, the other end of the cylinder is fixed to the inner wall of the rear shell 101, and a plurality of the cylinders are equidistantly installed on the edge of the main control board 12, one end of the stud passes through the main control board 12 and is threadedly connected with a nut 13, and the main control board 12 is provided with a screw hole for installing the stud. After the main control board 12 and the stud are installed, there is a gap between the main control board 12 and the fan 61, so that the wind fanned out by the fan 61 can pass through the gap between the main control board 12 and the camera assembly 2, thereby dissipating or cooling the main control board 12 and other electronic components.

[0064] Based on the above-described driving recorder, the present invention further proposes a control system for the driving recorder, including a temperature sensor 14 for real-time sensing of the temperature value inside the housing 1, a ventilation mechanism 6 capable of blowing cold air or hot air into the housing 1, a controller 10 for controlling the ventilation mechanism 6 to blow cold air or hot air according to the temperature value sensed by the temperature sensor 14, and a battery board 11 for powering the temperature sensor 14 and the ventilation mechanism 6, wherein the temperature sensor 14 and the ventilation mechanism 6 are both electrically connected to the controller 10, and the controller 10 is electrically connected to the battery board 11;

[0065] It also includes a main control board 12, a focus fine-tuning mechanism 5 and a camera assembly 2, wherein the camera assembly 2 is used to take photos or videos of the front of the vehicle when the vehicle is driving, and the main control board 12 is used to control the camera assembly 2 and the focus fine-tuning mechanism 5 to work or stop, so that the driving recorder can record the front video while driving.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
