[0026] Please refer to Figures 1-5, an embodiment provided by the present utility model: a protection mechanism for a driving recorder, including a protection housing 1, a transmission mechanism 8 and a buffer mechanism 9. A fixed block 3 is fixedly connected to the top of the protection housing 1. A movable door 5 is rotatably arranged on the front end face of the protection housing 1. A transparent window 4 is fixedly arranged on the movable door 5. An installation cavity 6 is arranged inside the protection housing 1. A wire inlet hole 13 communicating with each other is opened on the rear end face of the installation cavity 6. A clamping plate 7 is movably arranged inside the installation cavity 6. Transmission mechanisms 8 are arranged at both ends of the clamping plate 7. The transmission mechanism 8 includes a fixed slot 801, and the fixed slot 801 is opened at both ends of the installation cavity 6. A first slide bar 802 is fixedly arranged inside the fixed slot 801. The outer wall of the first slide bar 802 is slidably connected with a first slider 804, and the first slider 804 is fixedly connected to the outer wall of the clamping plate 7 close to it. A first spring 803 is fixedly connected to one side of each of the two first sliders 804 away from each other. Clamping grooves 10 are opened on one side of each of the two clamping plates 7 close to each other. A driving recorder body 11 is installed inside the clamping groove 10;

[0027] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, when in use, when the driving recorder body 11 fails and needs to be disassembled and repaired, pull the two clamping plates 7 in the direction away from each other. When the two clamping plates 7 move to a suitable position, take out the driving recorder body 11 from the clamping groove 10, so as to complete the disassembly of the driving recorder body 11. When the driving recorder body 11 needs to be installed after being repaired, pull the two clamping plates 7 in the direction away from each other again. When the two clamping plates 7 move to a suitable position, place the driving recorder body 11 between the two clamping grooves 10, and then release the clamping plates 7. At this time, the elasticity of the first spring 803 can be utilized to drive the two clamping plates 7 to move in the direction close to each other until they are in contact with the outer wall of the driving recorder body 11 and clamp it effectively, so as to complete the installation of the driving recorder body 11. By facilitating the disassembly and assembly of the driving recorder body 11, the working efficiency of the driving recorder can be improved. At the same time, when the protection housing 1 shakes due to impact, the elasticity of the first spring 803 can also effectively slow down the shaking received by the driving recorder body 11, thereby improving the protection effect of the driving recorder body 11, and solving the problem that through the mutual cooperation of the anti-collision housing and multiple springs to achieve the protection effect, but when the driving recorder fails, it is not convenient to disassemble, repair and install, which will affect the working efficiency of the driving recorder.

[0028] On both sides of the installation cavity 6, buffer cavities 12 are provided. Inside the buffer cavities 12, a buffer mechanism 9 is arranged. The buffer mechanism 9 includes a movable plate 904, and the movable plate 904 is movably arranged inside the buffer cavity 12. On one side of each of the two movable plates 904 away from each other, a buffer rod 908 is fixedly connected, and one end of the buffer rod 908 penetrates through the buffer cavity 12 and is fixedly connected to the outer wall close to the protection plate 2. On one side of each of the two movable plates 904 close to each other, a first hinge block 905 is fixedly connected. On one side of each of the two first hinge blocks 905 close to each other, a connecting rod 906 is hinged. On one side of each of the two connecting rods 906 close to each other, a second hinge block 907 is hinged. On one side of each of the two second hinge blocks 907 close to each other, a second slider 902 is fixedly connected. The surface of the second slider 902 is movably penetrated by a second sliding rod 903. At one end of each of the two second sliders 902 away from each other, a second spring 901 is fixedly connected. Protection plates 2 are arranged on both sides of the protection housing 1;

[0029] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when in use, when being impacted, it will drive the protection plate 2 to move at this time. The movement of the protection plate 2 drives the buffer rod 908 to move. The movement of the buffer rod 908 drives the movable plate 904 to move. The movement of the movable plate 904 drives the first hinge block 905 to move. Through the mutual cooperation of the connecting rod 906 and the second hinge block 907, the movement of the first hinge block 905 drives the second slider 902 to slide on the second sliding rod 903. The sliding of the second slider 902 will squeeze the second spring 901 to cause the second spring 901 to deform. The elastic force of the second spring 901 can effectively reduce the impact force received by the protection plate 2, thereby reducing the shaking received by the protection housing 1, and further improving the protection effect of the driving recorder body 11.

[0030] Working principle: In this application, when the driving recorder body 11 malfunctions and needs to be disassembled and repaired, pull the two clamping plates 7 in the direction away from each other. When the two clamping plates 7 move to a suitable position, take out the driving recorder body 11 from the clamping groove 10, thus completing the disassembly of the driving recorder body 11. When the driving recorder body 11 needs to be installed after being repaired, pull the two clamping plates 7 in the direction away from each other again. When the two clamping plates 7 move to a suitable position, place the driving recorder body 11 between the two clamping grooves 10, and then release the clamping plates 7. At this time, the elasticity of the first spring 803 can be used to drive the two clamping plates 7 to move in the direction close to each other until they contact the outer wall of the driving recorder body 11 and effectively clamp and fix it, thus completing the installation of the driving recorder body 11. By facilitating the disassembly and assembly of the driving recorder body 11, the working efficiency of the driving recorder can be improved. At the same time, when the protective housing 1 shakes due to impact, the elasticity of the first spring 803 can also effectively reduce the shaking force received by the driving recorder body 11, thereby improving the protection effect of the driving recorder body 11. Secondly, when being impacted, it will drive the protective plate 2 to move at this time. The movement of the protective plate 2 drives the buffer rod 908 to move. The movement of the buffer rod 908 drives the movable plate 904 to move. The movement of the movable plate 904 drives the first hinge block 905 to move. The movement of the first hinge block 905 drives the second slider 902 to slide on the second slide rod 903 through the mutual cooperation of the connecting rod 906 and the second hinge block 907. The sliding of the second slider 902 will squeeze the second spring 901 to cause the second spring 901 to deform. The elasticity of the second spring 901 can effectively reduce the impact force received by the protective plate 2, thereby reducing the shaking received by the protective housing 1, and further improving the protection effect of the driving recorder body 11.
