[0084] The conduit 26 is made of a hard material. At least one linkage rod 10 is provided between the guide ring 11 and the rotating ring 21. The selection of a hard material and the provision of the linkage rod 10 can improve the stability of the guide ring 11 when it rotates with the compression box 24 and the rotating ring 21 on the housing 15.

[0085] The multifunctional driving mechanism comprises:

[0086] An inner gear ring 17, wherein the inner gear ring 17 is fixedly connected to the support tube 5 via a positioning rod 39, and the inner gear ring 17 is concentric with the housing 15;

[0087] A rotating ring 21 is rotatably mounted on the housing 15 , and an outer gear ring 20 and a vertical plate 22 are fixedly mounted on the rotating ring 21 ;

[0088] A motor 18 is fixedly mounted on the housing 15 , and a driving gear 19 is fixedly mounted on the output shaft of the motor 18 and meshes with the outer gear ring 20 ;

[0089] A telescopic transmission shaft 16 is rotatably mounted on the vertical plate 22.

[0090] The multifunctional driving mechanism further comprises:

[0091] A driven frame 25 fixedly mounted on the push-pull rod 27, wherein a slider 28 is slidably mounted in the driven frame 25;

[0092] The driving handle 29 is fixedly mounted on the telescopic transmission shaft 16 , and a linkage shaft 36 rotatably connected to the slider 1 28 is fixedly mounted on one end of the driving handle 29 away from the telescopic transmission shaft 16 .

[0093] In this embodiment, the motor 18 is configured to cooperate with the driving gear 19 to drive the outer gear ring 20 to rotate, and the outer gear ring 20 can drive the rotating ring 21 to rotate. The rotating ring 21 can drive the telescopic transmission shaft 16 to rotate through the vertical plate 22, and the movable gear 23 is configured to cooperate with the inner gear ring 17, so that the telescopic transmission shaft 16 rotates around the housing 15 while the telescopic transmission shaft 16 can rotate on its own. The telescopic transmission shaft 16 rotates around the housing 15 and cooperates with the slider 2 30 to drive the movable frame 7 to move back and forth in the guide frame 6, and the slider 2 30 will move back and forth in the movable frame 7. The movable frame 7 can drive the scraping strip 8 to move back and forth. The spring 32 pulls the circular baffle, so that the guide rod 31 pushes the scraping strip 8 to always press on the windshield, and cooperates with the reciprocating movement of the scraping strip 8 to achieve the wiping process of fog.

[0094] The telescopic transmission shaft 16 can drive the driving handle 29 to rotate by rotating itself. The driving handle 29 can make the linkage shaft 36 rotate with the telescopic transmission shaft 16 as the axis, and the sliding block 28 and the driven frame 25 cooperate to drive the push-pull rod 27 to move back and forth. The push-pull rod 27 can drive the piston plate 37 to move back and forth in the compression box 24, so that the external air can be sucked into the compression box 24 through the air inlet 38, and the air in the compression box 24 can be sent into the guide ring 11 through the conduit 26. In this way, the guide ring 11 can be continuously filled with air during the defogging process. The air in the guide ring 11 can enter the housing 15 through the strip hole 34, thereby sending out the heat generated by the driving recorder body 9 when working, so that the hot air is sprayed onto the windshield in front of the driving recorder body 9 through the air jet hole 33, further improving the defogging effect, and the heat dissipation fins 35 are used to facilitate the heat dissipation of the driving recorder body 9, thereby improving the heat dissipation effect.

[0095] The coordinated arrangement of the support rod 14 and the support tube 5 facilitates the adjustment of the working position of the guide frame 6. Thus, after the mounting assembly is fixed to the windshield, the position of the guide frame 6 can still be adjusted to facilitate the pressing of the scraping strip 8 onto the windshield, which is more convenient. By rotating the fixing screw 2 13, the fixing screw 2 13 can be pressed onto the support rod 14, thereby achieving the fixation of the support rod 14.

[0096] In summary, the working principle of the present invention is:

[0097] In terms of equipment installation, the distance adjustment component and the shell 15 are firmly fixed on the adjustment box 1. This basic connection method provides a stable structure for the realization of subsequent functions; the bonding part 4 is fixed to the windshield of the car with double-sided tape. The use of double-sided tape has the characteristics of easy operation and fast installation, and can ensure a certain bonding strength, so that the equipment is firmly attached to the surface of the windshield; and the mounting base 3 and the adjustment box 1 are rotatably connected through the support shaft 2. This design is very flexible; in actual use, the driver can manually adjust the working angle of the adjustment box 1 according to his own needs and the angle of the vehicle windshield; since the driving recorder body 9 is installed on the adjustment The adjusting box 1 is on the hinged portion 1, so the change in the angle of the adjusting box 1 also achieves precise adjustment of the working angle of the driving recorder body 9, thereby ensuring that the driving recorder can record the road conditions in front of the vehicle at the best viewing angle. In order to fix the adjusting box 1 at a predetermined angle, the present invention adopts a method of rotating the fixing screw 12. When the fixing screw 12 is rotated, the end of the screw gradually presses the support shaft 2. As the pressure increases, the relative rotation between the support shaft 2 and the mounting base 3 is restricted, thereby achieving the locking of the angle of the adjusting box 1, ensuring that the driving recorder maintains a stable working angle during driving, and avoiding the deviation of the recording viewing angle due to factors such as vehicle bumps.

[0098] In realizing the defogger function, the present invention adopts a set of efficient mechanical transmission and gas circulation systems; the motor 18 serves as the power source of the entire defogger system, and provides the system with continuous and stable power output through the cooperation with the drive gear 19; when the motor 18 is running, it drives the drive gear 19 to rotate, and the drive gear 19 and the outer gear ring 20 are meshed with each other, thereby driving the outer gear ring 20 to perform circular motion; the rotation of the outer gear ring 20 drives the rotating ring 21 to rotate synchronously through the gear transmission relationship; the rotating ring 21 is connected to the telescopic transmission shaft 16 through the vertical plate 22, so that the rotation of the rotating ring 21 can drive the telescopic transmission shaft 16 to rotate around the shell 15; at the same time, the movable gear 23 is cooperated with the inner gear ring 17, so that the telescopic transmission shaft 16 can also rotate itself during the rotation around the shell 15; this composite motion mode is the key to realizing the defogger function;

[0099] When the telescopic transmission shaft 16 rotates around the housing 15, it is connected to the movable frame 7 through the slider 2 30; the slider 2 30 can slide back and forth in the movable frame 7 and cooperate with the guide frame 6, so that the movable frame 7 can move back and forth stably in the guide frame 6; when the telescopic transmission shaft 16 rotates, it drives the slider 2 30 to move, and the movement of the slider 2 30 in turn pushes the movable frame 7 to move up and down in the guide frame 6; the movable frame 7 is connected to the scraping strip 8, so that the reciprocating movement of the movable frame 7 can drive the scraping strip 8 to move back and forth on the surface of the windshield; in order to ensure that the scraping strip 8 can always fit tightly on the windshield, the present invention uses the pulling effect of the spring 32 on the circular baffle; the tension of the spring 32 is transmitted to the scraping strip 8 through the guide rod 31, so that the scraping strip 8 can be pressed against the windshield with appropriate pressure at any time; in this way, during the reciprocating movement of the scraping strip 8, the fog on the surface of the windshield can be effectively wiped clean, ensuring that the driving recorder body 9 has a clear front view;

[0100] At the same time, the rotation of the telescopic transmission shaft 16 also plays an important role; the telescopic transmission shaft 16 drives the driving handle 29 to rotate through its own rotation, and the driving handle 29 is connected to the linkage shaft 36, so that the linkage shaft 36 rotates with the telescopic transmission shaft 16 as the axis; the rotation of the linkage shaft 36 drives the push-pull rod 27 to reciprocate through the cooperation of the slider 28 and the driven frame 25; one end of the push-pull rod 27 is connected to the piston plate 37, and the piston plate 37 is located in the compression box 24; when the push-pull rod 27 reciprocates, it drives the piston plate 37 to reciprocate in the compression box 24; when the piston plate 37 moves backward, the space in the compression box 24 increases, the air pressure decreases, and the external air is sucked into the compression box 24 through the air inlet 38; when the piston plate 37 moves forward, the space in the compression box 24 decreases, the air pressure increases, and the gas in the compression box 24 is sent into the guide ring 11 through the conduit 26; through such reciprocating motion, the guide ring 11 can be continuously filled with gas;

[0101] The gas in the guide ring 11 enters the shell 15 through the strip holes 34. This process not only realizes the transmission of gas, but also has the important dual functions of heat dissipation and demisting. The driving recorder body 9 generates heat during operation. After the gas in the guide ring 11 enters the shell 15, it can take away the heat generated by the driving recorder body 9 during operation, and through heat exchange, the heat is discharged together with the gas. At the same time, these hot air are sprayed onto the windshield in front of the driving recorder body 9 through the air jet holes 33. The hot air can quickly increase the temperature of the windshield surface, reduce the condensation of water vapor in the air on the glass surface, and further improve the demisting effect. In addition, the heat dissipation fins 35 provided in the shell 15 can increase the contact area with the air, which is convenient for quickly dissipating the heat generated by the driving recorder body 9, ensuring that the driving recorder always remains in the appropriate operating temperature range during long-term operation, thereby improving the stability and service life of the equipment.

[0102] In terms of adjustment after equipment installation, the coordinated setting of the support rod 14 and the support tube 5 provides great convenience; after the installation assembly is fixed to the windshield by the adhesive portion 4, if it is found that the scraping strip 8 is not accurately pressed onto the windshield, or the position of the scraping strip 8 on the windshield needs to be adjusted, it can be achieved by adjusting the relative position of the support rod 14 and the support tube 5; during specific operation, the fixing screw 2 13 can be loosened first to allow the support rod 14 to move freely in the support tube 5; according to actual needs, the extension length and angle of the support rod 14 can be adjusted to achieve precise adjustment of the working position of the guide frame 6; when adjusted to the appropriate position, the fixing screw 2 13 is rotated so that the end of the fixing screw 2 13 is pressed onto the support rod 14, and the support rod 14 is fixed in the support tube 5 by friction, ensuring that the guide frame 6 and the scraping strip 8 connected thereto can be stably maintained in the predetermined working position, providing reliable guarantee for efficient demisting;
