DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5The utility model provides the following technical solutions: a driving recorder with conveniently adjustable angle, comprising a bracket 1, an adhesive sheet 3 is bonded to the upper side of the bracket 1, a rotating shaft 7 is rotatably connected to the lower side of the bracket 1, a connecting rod 2 is installed on the outer side of the rotating shaft 7, a camera 4 is connected to the lower end of the connecting rod 2, a display screen 5 is installed on the front side of the camera 4, and a camera 6 is installed on the rear side of the camera 4; a mounting groove 8 is provided inside the rotating shaft 7, a spring 9 is connected inside the mounting groove 8, a moving rod 10 is installed at the end of the spring 9, and a positioning wheel 11 is rotatably connected to the end of the moving rod 10; a fixing cover 12 is installed on the lower side of the bracket 1, and a positioning groove 13 is provided on the inner side of the fixing cover 12;

[0027] Furthermore, the moving rod 10 forms an elastic structure with the rotating shaft 7 through the spring 9, and the moving rod 10 is distributed at equal angles with respect to the transverse center line of the rotating shaft 7, so that the moving rod 10 can be flexibly retracted and extended, so that the positioning wheel 11 can smoothly cross the positioning groove 13 to move; the positioning wheel 11 and the positioning groove 13 are engaged with each other, and the connecting end of the positioning groove 13 is a smooth arc structure, and the positioning wheel 11 and the positioning groove 13 are used to position the angle-adjustable camera 4 to ensure its stability;

[0028] The bracket 1 is bonded to the front glass in the car through the adhesive sheet 3 to fix the driving recorder. The camera 6 shoots toward the front position, and the camera 4 is moved so that the connecting rod 2 rotates on the bracket 1 through the rotating shaft 7. The angle of the camera 4 is adjusted so that the camera 6 adapts to the size of the vehicle model and shoots toward the front position of the vehicle. When the connecting rod 2 rotates, the moving rod 10 can be driven to drive the positioning wheel 11 to rotate synchronously, and the positioning wheel 11 rolls in the positioning groove 13. When the positioning wheel 11 needs to cross the positioning groove 13, the moving rod 10 is squeezed to move. At the same time, the moving rod 10 squeezes and accumulates force on the spring 9, so that the positioning wheel 11 smoothly follows the rotation of the rotating shaft 7. When the position of the positioning wheel 11 corresponds to the position of the positioning groove 13, the spring 9 can drive the moving rod 10 to reset and move, thereby controlling the positioning wheel 11 to reset and get stuck in the positioning groove 13, limiting the rotating shaft 7, and thus limiting the angle-adjusted camera 4 to ensure its stability in use.

[0029] Furthermore, a heating wire 14 is connected to the rear side of the camera 4, and an injection assembly for assisting the camera 6 in defogger is arranged on the rear side of the camera 4; the injection assembly includes an air cylinder 15 and a limiting cylinder 19 installed on the rear side of the camera 4, an end of the air cylinder 15 is connected to an external heat-conducting column 16, an expansion airbag a17 is connected to the interior of the external heat-conducting column 16, an end of the expansion airbag a17 is connected to an internal heat-conducting column 18, an expansion airbag b20 is installed inside the limiting cylinder 19, an end of the expansion airbag b20 is connected to a connecting rod 21, and an end of the connecting rod 21 is connected to a piston 22;

[0030] Specifically, the heating wire 14 is sleeved on the outside of the air cylinder 15, and the opening of the air cylinder 15 faces the camera 6. The heating wire 14 can be used to heat the airflow in the air cylinder 15, and the heated airflow is sprayed to the position of the camera 6 to defog it; the inner heat-conducting column 18 and the outer heat-conducting column 16 are slidably connected, and the total length of the inner heat-conducting column 18 and the outer heat-conducting column 16 is greater than the shortest distance between the air cylinder 15 and the limiting cylinder 19, so that the inner heat-conducting column 18 can be moved out to contact the limiting cylinder 19 to conduct heat; the piston 22 is slidably connected to the air cylinder 15, and one end of the air cylinder 15 is slidably penetrated by a connecting rod 21, so that the connecting rod 21 can smoothly drive the piston 22 to move in the air cylinder 15 to extract and discharge the airflow;

[0031] When fog appears on the camera 6, the power supply of the heating wire 14 can be connected, and the heating wire 14 starts to heat up to defog the camera 6. At the same time, due to the heat of the heating wire 14, the air in the air cylinder 15 is heated and heated. At the same time, the heat on the air cylinder 15 is transferred to the outer heat-conducting column 16, and the gas in the expansion airbag a17 is heated and expanded, so that the expansion airbag a17 expands and pushes the inner heat-conducting column 18 to move until one end of the inner heat-conducting column 18 contacts the limiting cylinder 19, and cooperates with the heat conduction of the inner heat-conducting column 18 to transfer the heat to the limiting cylinder 19, and the gas in the expansion airbag b20 is heated. The expansion causes the expansion airbag b20 to expand and push the connecting rod 21 to move, thereby driving the piston 22 to move in the air cylinder 15, spraying hot gas to the camera 6, and assisting in accelerating the defogger of the camera 6. After the defogger is completed, the heating wire 14 can be powered off, and after cooling, the expansion airbag a17 and the expansion airbag b20 are reset and contracted, pulling the inner heat-conducting column 18 into the outer heat-conducting column 16, and pulling the connecting rod 21 to drive the piston 22 to reset and move, and the airflow is sucked into the air cylinder 15 for storage and use. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
