[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] When a vehicle is driving, it is often necessary to observe the traffic situation behind through the rear window. In order to prevent rain or dirty windows from affecting the rear view on rainy days, a wiper is provided on the rear window for cleaning the rear window.

[0030] However, the wipers are always exposed, resulting in greater wind noise and wind resistance during vehicle driving, affecting the driver's driving experience.

[0031] Embodiment 1

[0032] Reference Figure 1 and Figure 2 A first aspect of an embodiment of the present application provides a hidden wiper, comprising a mounting plate 1 and a window 2, wherein the mounting plate 1 is located on one side of the window 2. In this embodiment, the window 2 is the rear window of the vehicle, and the mounting plate 1 is a plate body under the rear window. The window 2 is sealed and connected to one side edge of the mounting plate 1.

[0033] The hidden wiper also includes a wiper body 3 , which includes a mounting shaft 31 and a wiper blade 32 . A mounting hole 11 is provided on the mounting plate 1 . The mounting shaft 31 is movably arranged in the mounting plate 1 , and the wiper blade 32 is arranged on the mounting shaft 31 .

[0034] Reference Figure 2 and Figure 3 , wherein, when the mounting shaft 31 is in an extended state, and when not working, the wiper blade 32 is in an initial position at the edge of one side of the window 2, the bottom surface of the wiper blade 32 is in the same plane as the surface of the window 2, and the wiper blade 32 returns to the initial position after the work is completed. The wiper blade 32 is always in contact with the surface of the window 2 during operation. When the mounting shaft 31 rotates, the wiper blade 32 can be driven to swing on the surface of the window 2 to clean the surface of the window 2. After the wiper blade 32 stops moving, it automatically returns to the initial position at the edge of one side of the window 2, which is convenient for subsequent retraction. After retraction, the wiper blade 32 is retracted to the bottom of the window 2 for easy hiding.

[0035] The first driving part 33 is used to drive the installation shaft 31 to reciprocate along the axial direction of the installation hole 11, so that the installation shaft 31 can be located in the installation hole 11, or at least a part of the installation shaft 31 can be located outside the installation hole 11;

[0036] Among them, the first driving part 33 is arranged in the mounting plate 1 and is connected to the mounting shaft 31 in transmission. When there is no need to clean the surface of the window 2, the first driving part 33 controls the mounting shaft 31 to be retracted, driving the wiper plate 32 to be retracted in the initial position, or when the window 2 needs to be cleaned, the mounting shaft 31 is controlled to be extended, driving the wiper plate 32 to be extended in the initial position.

[0037] When in the extended state, the second driving part 34 drives the mounting shaft 31 to rotate, thereby driving the wiper blade 32 to swing back and forth from the initial position, or rotating the wiper blade 32 to the initial position when stopping cleaning, so as to facilitate the extension and retraction of the wiper blade 32 by the first driving part 33.

[0038] The cover plate 4 is movably disposed on the mounting plate 1 , and when at least a portion of the mounting shaft 31 is located in the mounting hole 11 , the cover plate 4 shields the wiper body 3 .

[0039] Among them, when the wiper body 3 cleans the window 2, after the cover 4 is opened, the wiper body 3 can be raised and lowered, and when the wiper body 3 is cleaned, the wiper body 3 will not contact the cover 4. When the cover 4 covers the wiper body 3, the edge of the cover 4 is close to the edge of the window 2 and the surface of the mounting plate 1. At this time, the wiper body 3 is located under the cover 4, avoiding wind resistance and wind noise generated by the wiper body 3 when the vehicle is driving.

[0040] During the driving of the vehicle, the wiper body 3 is always located under the cover 4, and the wiper body 3 is in a retracted state. When the window 2 needs to be cleaned, the cover 4 is moved to expose the wiper body 3, and then the first driving part 33 is used to drive the mounting shaft 31 to slide upward, and the wiper body 3 is extended upward out of the cover 4, and then the second driving part 34 is used to drive the mounting shaft 31 to drive the wiper plate 32 to rotate, and the window 2 is cleaned. When the cleaning is completed, the wiper plate 32 is rotated to the original position, and then the wiper body 3 is retracted, and the cover 4 is driven to cover the wiper body 3. By hiding the wiper body 3 when not in use and covering the wiper body 3 with the cover 4, wind noise and wind resistance generated by the wiper body 3 are avoided, and the aesthetics of the vehicle is improved.

[0041] In some embodiments, the wiper body 3 further includes a mounting sleeve 12 , the mounting sleeve 12 is inserted into the mounting hole 11 , the mounting shaft 31 is slidably inserted into the mounting sleeve 12 , and a first sealing member 13 is provided between the mounting sleeve 12 and the mounting plate 1 .

[0042] Among them, the mounting shaft 31 is set to slide along the axial direction of the mounting sleeve 12, and the mounting shaft 31 is guided by the mounting sleeve 12, so that the wiper blade 32 slides along the axial direction of the mounting sleeve 12 when the wiper blade 32 is raised or lowered, and the mounting sleeve 12 and the mounting plate 1 are sealed and connected through the first sealing member 13, so that the sealing performance of the entire device is effectively improved, and rainwater is effectively prevented from entering the interior.

[0043] In some embodiments, the wiper body 3 also includes a wiper cap 35, which is disposed on the mounting shaft 31. When at least part of the mounting shaft 31 is located in the mounting hole 11, the wiper cap 35 can be sealed in the mounting hole 11. A bellows 15 is disposed between the wiper cap 35 and the first seal 13, and the bellows 15 is sealed and connected to the wiper cap 35 and the first seal 13.

[0044] The wiper cap 35 moves synchronously with the wiper blade 32. The wiper cap 35 is covered on the end of the mounting shaft 31, and a notch is opened on the side wall of the wiper cap 35. The wiper blade 32 extends out of the notch. When the wiper blade 32 swings, the wiper cap 35 rotates synchronously with the wiper blade 32 to prevent rainwater from entering from the mounting sleeve 12, thereby improving the sealing of the entire device.

[0045] At the same time, a second seal 14 coaxially arranged on the mounting shaft 31 is also provided in the wiper cap 35. The second seal 14 rotates relative to the mounting shaft 31. When the mounting shaft 31 rotates, the second seal 14 remains relatively still. One end of the bellows 15 is sealed with the second seal 14, and the other end is sealed with the first seal 13. The wiper cap 35 is covered on the bellows 15, and the bellows 15 closes the gap of the wiper cap 35. During the rotation of the wiper blade 32, the bellows 15 remains relatively still. During the operation of the wiper blade 32, the bellows 15 always covers the gap between the mounting shaft 31 and the mounting sleeve 12. Rainwater falls from the wiper cap 35 and the bellows 15 to prevent rainwater and other debris from entering, thereby improving the sealing of the entire device.

[0046] Reference Figure 2 and Figure 3 And through the telescopic structure of the bellows 15 itself, the bellows 15 is driven to telescope synchronously during the lifting and lowering process of the wiper body 3, thereby ensuring that the bellows 15 always covers the gap between the mounting shaft 31 and the mounting sleeve 12.

[0047] In other embodiments, the bellows 15 may also be a soft film made of other waterproof materials, which can always cover the gap between the mounting shaft 31 and the mounting sleeve 12 during the extension and retraction process of the wiper body 3 .

[0048] In some embodiments, the first driving unit 33 includes:

[0049] A rack 331, the rack 331 is fixedly arranged on the extending end of the installation shaft 31 along the length direction of the installation shaft 31;

[0050] The rack 331 is welded on the side wall of the installation shaft 31 along the axial direction of the installation shaft 31 , and the installation shaft 31 can be driven to move back and forth by driving the rack 331 to slide.

[0051] The gear 332 is rotatably arranged and meshes with the rack 331 for transmission connection;

[0052] Among them, the rotation axis of the gear 332 is perpendicular to the axial direction of the mounting shaft 31, and the rack 331 is driven to slide back and forth through the meshing transmission between the gear 332 and the rack 331. In other embodiments, the gear 332 may include one or more gears 332 to form a gear 332 group, thereby performing.

[0053] The first motor 333 , whose output shaft is transmission-connected with the gear 332 , is used to drive the rack 331 to slide via the gear 332 .

[0054] The first motor 333 is fixedly arranged below the mounting plate 1, and the output shaft of the first motor 333 is coaxially fixedly connected with the gear 332. The first motor 333 can be a servo motor. By controlling the forward and reverse rotation of the first motor 333, the gear 332 can be driven to reciprocate, thereby driving the mounting shaft 31 to extend and retract, thereby realizing the lifting and lowering of the wiper body 3.

[0055] In some other embodiments, the gear 332 may also be driven by other driving members, such as a motor pulley device, etc., and the first driving part 33 may also be other devices, such as a hydraulic cylinder, etc., to achieve reciprocating motion.

[0056] Reference Figure 2 In some embodiments, the hidden wiper further includes a third driving unit 41, the cover plate 4 is rotatably disposed on the mounting plate 1, and the rotation axis is perpendicular to the central axis of the mounting hole 11, the movable end of the cover plate 4 faces one side of the mounting hole 11, and the third driving unit 41 is used to drive the cover plate 4 to rotate.

[0057] Among them, the movable direction of the installation shaft 31 is nearly perpendicular to the surface of the window 2, and the initial position of the wiper body 3 is located at the edge of the window 2. Therefore, the cover plate 4 is rotated and set, and the movable end of the cover plate 4 contacts the window 2. When the cover plate 4 is flipped upward, a gap is exposed between the cover plate 4 and the window 2. The installation shaft 31 drives the wiper body 3 to rise and is exposed at the gap. At this time, the wiper plate 32 can be driven to start swinging by rotating the installation shaft 31, and it rotates out from the bottom of the cover plate 4 and starts cleaning along the surface of the window 2.

[0058] When the wiper body 3 is retracted, the wiper blade 32 returns to the initial position and leaves the window 2. The wiper blade 32 can be retracted by installing the shaft 31, and then the cover plate 4 is rotated toward the side close to the window 2 until the cover plate 4 fits against the edge of the window 2, so that the wiper body 3 can be covered.

[0059] In some embodiments, the third driving part 41 can be a second motor, which is disposed on the mounting plate 1 and is drivingly connected to the cover plate 4 . The cover plate 4 can be opened or closed by driving the second motor to rotate forward or reverse.

[0060] In other embodiments, the third driving unit 41 may also be driven by other means, such as by a motor gear 332 or a pulley, or a hydraulic cylinder may be provided on the mounting plate 1 to push the cover plate 4 to move, thereby realizing the opening and closing of the cover plate 4.

[0061] Reference Figure 1 and Figure 2 In some embodiments, the mounting hole 11 is disposed at a middle position of the mounting plate 1 on a side close to the window 2 .

[0062] Among them, the mounting hole 11 is opened in the middle position, and when the wiper body 3 is working, the wiper blade 32 swings with the mounting hole 11 as the center. When the wiper blade 32 is located at the edge of one side of the mounting hole 11, it is the actual position, and when it rotates to the edge of the other side, it is the end position. The wiper blade 32 can clean the window 2 by swinging between the two positions.

[0063] In some embodiments, a receiving groove 16 for receiving the wiper body 3 is provided on one side of the mounting plate 1 close to the window 2, and the mounting hole 11 is located at the bottom of the receiving groove 16. When the cover plate 4 is closed, the receiving groove 16 is covered and flush with the surface of other parts of the mounting plate 1.

[0064] The side of the mounting plate 1 close to the window 2 is recessed inward to form a receiving groove 16. When the wiper body 3 is in the retracted state, the wiper body 3 is located in the receiving groove 16. After the cover plate 4 covers the receiving groove 16, the cover plate 4 is flush with other positions of the mounting plate 1, effectively reducing the wind resistance and wind noise generated during the driving of the vehicle.

[0065] In some embodiments, the bottom of the receiving groove 16 is communicated with the outside.

[0066] Specifically, during the cleaning process, specifically during the cleaning process of rainwater when it rains, the wiper blade 32 is extended and swings back and forth on the surface of the window 2. After the rainwater is wiped off, the rainwater enters the receiving groove 16. Since the bottom of the receiving groove 16 is connected to the outside, the rainwater flows out directly, avoiding the accumulation of rainwater or entering the mounting plate 1, thereby improving the waterproofness of the entire device.

[0067] In some embodiments, when the cover plate 4 is closed, its edge is in contact with the surface of the window 2 .

[0068] During driving, the cover plate 4 fits against the vehicle body to prevent debris from entering the receiving groove 16 and reduce the wind resistance and wind noise. At the same time, when it rains and the cover plate 4 is not opened, rainwater is prevented from entering the receiving groove 16, further improving the sealing performance of the entire device.
