DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0017] Specific implementation examples Figure 1-3As shown, a telescopic hidden wiper comprises a mounting rod 2 matched with a rear glass 1 of a car and a first wiper blade 3 arranged on the mounting rod 2, a driving shaft 4 drivingly connected to a power output end of a driving motor is arranged on the mounting rod 2, a guide groove 5 and a telescopic rod 6 guiding and cooperating with the guide groove 5 are arranged on the mounting rod 2, a second wiper blade 7 is arranged on the telescopic rod 6, the telescopic rod 6 has the freedom to move along the guide groove 5 by means of a telescopic driving unit, the second wiper blade 7 is overlapped with the first wiper blade 3 left and right, in this embodiment, the first wiper blade 3 is located on the left side of the second wiper blade 7, the first wiper blade 3 is connected to the mounting rod 2 by means of a supporting frame, and the second wiper blade 7 is connected to the telescopic rod 6 by means of a supporting frame; by A guide groove 5 is added to the installation rod 2 of the wiper, and a telescopic rod 6 is arranged in the guide groove 6. A second wiper blade 7 is arranged on the telescopic rod 6 and overlapped with the first wiper blade 3 on the installation rod 2, and the overlapping length is greater than the extension distance of the telescopic rod 6; the telescopic drive unit controls the telescopic rod 6 to move along the guide groove 5 and extend or contract on the installation rod 2; when the telescopic rod 6 is extended, the first wiper blade 3 and the second wiper blade 7 increase the scraping area of the rear glass 1 of the vehicle, reduce the water droplets or dust remaining on the rear glass 1 of the vehicle, and increase the field of view of the rear glass 1 of the vehicle when the road is dusty or in rainy weather during driving; when the telescopic rod 6 is contracted, the first wiper blade 3 and the second wiper blade 7 will not interfere with each other.
[0018] When the upper end of the mounting rod 2 is at the highest point, the telescopic rod 6 is in a retracted state; the telescopic drive unit includes a pair of linkage components that are symmetrically arranged along the plane where the axis of the mounting rod 2 and the axis of the drive shaft 4 are located, and the axis of the drive shaft 4 coincides with the projection of the center line of the rear glass 1 of the automobile on the horizontal plane, that is, the drive shaft 4 is located in the middle position in the length direction of the rear glass 1 of the automobile, and the telescopic rod 6 is extended and retracted with the left and right swing of the mounting rod 2 by means of the linkage components, thereby increasing the scraping area on the left and right sides of the rear glass 1 of the automobile;
[0019] The linkage assembly 8 includes a push rod 10, a connecting shaft 11 and an articulated rod 12. The connecting shaft 11 is fixed to the vehicle body. Both ends of the articulated rod 12 are hinged to the push rod 10 and the connecting shaft 11 respectively. The connecting shaft 11 is arranged on the outside of the mounting rod 2. A first slide groove 13 is arranged on the telescopic rod 6 near the connecting shaft 11. The push rod 10 forms a guiding match with the first slide groove 13. The angle α between the axis of the articulated rod 12 and the axis of the telescopic rod 6 is an acute angle. When the telescopic rod 6 is in a retracted state, the push rod 10 contacts the upper end of the first slide groove 13. When the upper end of the mounting rod 2 is at the highest point, the telescopic rod 6 is in a retracted state. When the driving motor transmits power to the driving shaft 4, so that the driving shaft 4 drives the mounting rod 2 to swing to the left, the mounting rod 2 drives the telescopic rod 6 to swing to the left. The push rod 10 in the linkage assembly located on the left side of the mounting rod 2 is affected by the push rod 10 it receives. When the first slide groove 13 is pushed to move to the left, the hinged rod 12 rotates along the connecting shaft 11, and the push rod 10 moves upward relative to the mounting rod 2. The push rod 10 drives the telescopic rod 6 to move upward along the guide groove 5, so that the telescopic rod 6 is extended on the mounting rod 2, and the scraping length of the first wiper blade 3 and the second wiper blade 7 is increased, thereby increasing the scraping area of the left end of the rear glass 1 of the automobile. The push rod 10 on the right side of the mounting rod 2 is driven by the telescopic rod 6 to drive the hinged rod 12 on the same side to swing to the left along the connecting shaft 11, and the push rod 10 moves downward relative to the mounting rod 2. When the upper end of the mounting rod 2 is at the highest point and the telescopic rod 6 is in the contracted state, when the driving shaft 4 drives the mounting rod 2 to swing to the right, the push rod 10 on the right side drives the telescopic rod 6 to move upward along the guide groove 5. When the upper end of the mounting rod 2 returns to the highest point, the push rods 10 on the left and right sides are reset. This satisfies the large area scraping of the rear glass 1 of the automobile with a large length-to-width ratio, and does not interfere with the vehicle body at the upper end of the rear glass 1 of the automobile.
[0020] When the wiper is turned off, it automatically resets to the lowest point of its movement trajectory, that is, at the bottom of the left or right side of the car rear glass 1. At this time, the angle α between the axes of the two hinged rods 12 and the axis of the telescopic rod 6 becomes smaller, and the hinged rod 12 is folded and hidden at the bottom of one side of the car rear glass 1, which has little impact on the appearance of the car.
[0021] The mounting rod 2 is provided with a second slide groove 14 corresponding to the first slide groove 13, and the upper and lower ends of the push rod 10 form a guiding cooperation with the first slide groove 13 and the second slide groove 14 respectively. When the mounting rod 2 swings to one side and the telescopic rod 6 extends, the push rod 10 on the other side disengages from the first slide groove 13 on the telescopic rod 6 and is only guided by the second slide groove 14. When the telescopic rod 6 contracts, the push rod 10 can smoothly enter the first slide groove 13 guided by the second slide groove 14, so that the extension distance of the telescopic rod 6 can be increased at the same length, so that the layout can be more reasonable.
[0022] A wiper support seat 9 is provided on the vehicle body, the power output end of the drive shaft 4 passes through the wiper support seat 9 and is connected to the mounting rod 2, and the connecting shaft 11 is fixed to the wiper support seat 9 by means of a connecting rod, thereby fixing the connecting shaft 11 to the vehicle body and reducing the need to open new holes on the vehicle body.
