[0035] As shown in the figure, a passenger car automatic driving radar and camera wiper comprises: a mounting base 7, the mounting base 7 has a pivot seat and an axle seat arranged in front and back; a driving unit 13, the driving shaft of the driving unit 13 is installed on the axle seat; a main driving arm 8, the main driving arm 8 is connected to the driving shaft through a key, and the other end of the main driving arm 8 is installed with a connecting rod 1 through a rivet 10, and the other end of the connecting rod 1 is connected to the rear end of the first cross bar 4 through the rivet 10; a first vertical rod 2, the lower end of the first vertical rod 2 is pivotally connected to the pivot seat, and the middle section is pivotally connected to the first cross bar 4; The middle section of the rod 4; the second vertical rod 3, the lower end of the second vertical rod 3 is pivoted to the front end of the first cross rod 4; the second cross rod 5, the rear end of the second cross rod 5 is pivoted to the upper end of the first vertical rod 2, and the middle section is pivoted to the middle section of the second vertical rod 2; the third cross rod 6, the rear end of the third cross rod 6 is pivoted to the upper end of the second vertical rod 3; the wiper blade fixing support 11, the two ends of the wiper blade fixing support 11 are respectively pivoted to the front end of the third cross rod 6 and the front end of the second cross rod 5, and the wiper blade fixing support 11 is installed with a wiper blade 12; wherein, the mounting base 7 is installed close to the radar and the camera.

[0036] In one embodiment of the utility model, the radar and camera lenses are self-rotating, and can rotate by themselves. The entire lens bottom mounting plate surface is a car sheet metal, and the wiper is telescopically arranged on the lower side of the sheet metal. When working, it is extended close to the radar and camera lenses to complete the stop, and the lens can be rotated back and forth to clean. When the wiper is not needed, it only needs to be retracted to hide under the sheet metal to avoid affecting the work of the radar and camera.

[0037] Specifically, the mounting base 7 is a bottom support, and is provided with a pivot seat and an axle seat for convenient pivot connection at the front and rear, wherein the axle seat is installed with a driving shaft of the driving unit 13, and the main driving arm 8 is connected to the driving shaft through a key connection for driving.

[0038] The horizontal bar, the vertical bar and the connecting rod 1 are combined into a telescopic mechanism. First, the mounting base 7 is kept stationary, the driving unit 13 is connected to the main driving arm 8 through a spline and fixed on the mounting base 7, and the driving unit 13 rotates to drive the main driving arm 8 to rotate; the main driving arm 8 and the connecting rod 1 are connected by rivets 10, and the main driving arm 8 and the connecting rod 1 are tightened by a tension spring 9, and the main driving arm 8 drives the connecting rod 1 to rotate;

[0039] The connecting rod 1 and the first cross bar 4 are connected by rivets 10, and the connecting rod 1 pushes the first cross bar 4 to move.

[0040] The first cross bar 4 is also riveted together with the first vertical bar 2 and the second vertical bar 3 by rivets.

[0041] The first vertical rod 2 is also riveted together with the pivot seat of the mounting base 7 and the second cross rod 5 by rivets.

[0042] The second vertical rod 3 is also riveted together with the second cross rod 5 and the third cross rod 6 by rivets.

[0043] The second cross bar 5 and the third cross bar 6 are also riveted together with the scraper blade fixing support 11 by rivets 10 .

[0044] During the movement, the first cross bar 4 will push the first vertical bar 2 and the second vertical bar 3 to rotate around the axis of the rivet riveted between the first vertical bar 2 and the mounting base 7 .

[0045] The first vertical rod 2 rotates, driving the second horizontal rod 5 to move.

[0046] During the movement of the second cross bar 5 , the second vertical bar 3 and the scraper fixing support 11 are pushed to rotate around the axis of the rivet connecting the second vertical bar 3 and the first cross bar 4 .

[0047] The second vertical rod 3 rotates, driving the third horizontal rod 6 to move.

[0048] During the movement of the third cross bar 6 , the scraper blade fixing support 11 will be pushed to rotate around the axis of the riveted rivet between the scraper blade fixing support 11 and the second cross bar 5 .

[0049] All of the above parts form a retractable structure.

[0050] In addition, the wiper blade 12 is riveted to the blade fixing support 11 by rivets, and only one riveted joint in the middle is riveted, which is convenient for swinging back and forth to adapt to the curved lens surface. Further, the front end of the wiper blade 12 is set as an arc structure, which has stronger adaptability.

[0051] The invention of the radar wiper is that when the wiper cleans the dirt on the radar and camera surface, the telescopic structure can always keep the wiper blade 12 in close contact with the radar and camera surface. The function is implemented as follows: the part that pushes the first crossbar 4 to move is not driven by the main drive arm 8, but a connecting rod 1 is added between the main drive arm 8 and the first crossbar 4, and the two ends of the connecting rod 1 are riveted to the main drive arm 8 and the first crossbar 4 respectively by rivets 10, and the connecting rod 1 can rotate around the main drive arm 8 and the first crossbar 4 respectively, and the main drive arm 8 and the connecting rod 1 are tightened by the tension spring 9, and when the main drive arm 8 runs at a specified position, the wiper blade 12 is close to the radar and camera surface, and the main drive arm 8 stops running and remains motionless. When the wiper is working to scrape dirt, the tension spring 9 tightens the connecting rod 1, so that the connecting rod 1 continuously gives thrust to the first crossbar 4, so that the telescopic structure pushes the wiper blade 12, and always keeps the wiper blade 12 in close contact with the radar and camera surface.

[0052] In addition, to prevent the connecting rod 1 and the main driving arm 8 from rotating freely, the main driving arm 8 and the connecting rod 1 are tightened by the tension spring 9, so that the connecting rod 1 can only rotate around the axis of the rivet riveted between the connecting rod 1 and the main driving arm 8 in the tensioning direction of the tension spring. A buffering limit block 14 is added between the main driving arm 8 and the connecting rod 1. The limit block 14 has a limiting function, so that the connecting rod 1 and the main driving arm 8 maintain a minimum angle, so that the tension spring 9 is always in a tensioned state.

[0053] Preferably, the driving unit 13 is configured as a waterproof motor with high durability.

[0054] In addition, the main driving arm 8 has a backward curvature to enhance the pressure resistance and make the rotation more stable.

[0055] In summary, when the wiper of the utility model is working, the lifting mechanism composed of the driving unit, the horizontal rod and the vertical rod lifts and rotates the wiper blade to the surface of the radar and camera lens. When the wiper is not working, the telescopic mechanism retracts the wiper blade into the inside of the radar and camera; that is, it ensures that the surface of the radar and camera can be cleaned at any time by using the wiper when the surface is dirty, and it also ensures that the wiper can be retracted into the inside of the radar and camera when the radar and camera are in operation, so as to prevent the wiper from blocking the radar and camera and affecting the judgment of the radar and camera.
