[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0051] Firstly, please see Figures 1 to 10 This application provides a vehicle window glass assembly 100. The vehicle window glass assembly 100 includes a glass body 1 and a cleaning device 2. The cleaning device 2 includes a transducer 21 disposed on the inner surface 101 of the glass body 1, and the transducer 21 is used to output vibrational mechanical energy to clean a local area of the glass body 1.
[0052] Understandably, the glass body 1 can be a single-layer structure or a multi-layer structure. A single-layer glass body 1 includes only one glass layer, while a multi-layer glass body 1 includes at least two glass layers. Optionally, the glass body 1 is a multi-layer structure, which allows it to have higher impact resistance. As an example, the glass body 1 is a windshield, such as a double-layer windshield. The glass body 1 includes two tempered glass layers and a polyvinyl butyral (PVB) interlayer film disposed between the two tempered glass layers. The toughness and adhesiveness of PVB can bind the fragments together when the glass breaks, preventing them from flying and injuring people, while maintaining a clear view. Furthermore, the glass body 1 can be a planar structure or a curved structure. The material of the glass body 1 can be ordinary glass or tempered glass.
[0053] Along the thickness direction of the glass body 1, the glass body 1 has two opposing surfaces, namely an inner surface 101 and an outer surface 102. Taking the application of the window glass assembly 100 on a vehicle 200 as an example, the inner surface 101 of the glass body 1 corresponds to the interior of the vehicle 200, and the outer surface 102 of the glass body 1 corresponds to the exterior of the vehicle.
[0054] The cleaning device 2 is used to clean the glass body 1. Specifically, the cleaning device 2 includes a transducer 21, which cleans the glass body 1. The transducer 21 is a device that converts electrical energy into mechanical vibration (e.g., ultrasound), so the output of the transducer 21 is vibrational mechanical energy. The transducer 21 is disposed on the inner surface 101 of the glass body 1. The vibrational mechanical energy output by the transducer 21 can activate the glass body 1 to vibrate. During the vibration of the glass body 1, dust, fog, or frost adhering to the surface of the glass body 1 can be shaken off, thereby cleaning the glass body 1. The transducer 21 is mainly used for targeted cleaning of local areas of the glass body 1. Compared with arranging a large number of transducers 21 on the glass body 1 to excite the entire glass body 1 for cleaning, this reduces the number of transducers 21 on the glass body 1, thereby reducing energy consumption. As an example, transducer 21 is used to clean a first region 104 on a local area of the glass body 1, that is, the first region 104 is a local area of the glass body 1. However, it should be noted that the number of transducers 21 in the window glass assembly 100 is not limited to one; it can also be two or three.
[0055] Furthermore, the transducer 21 is disposed on the inner surface 101 of the glass body 1. The transducer 21 can be directly disposed on the inner surface 101, or it can be indirectly disposed on the inner surface 101 through other components. Compared to the method of transmitting vibrational mechanical energy through a gap between the transducer 21 and the glass body 1, both direct and indirect disposal methods allow the vibrational mechanical energy output by the transducer 21 to be transmitted to the glass body 1 with less loss, thereby saving energy. In addition, the transducer 21's placement on the inner surface 101 of the glass body 1 can effectively eliminate frost and fog on the inner surface 101.
[0056] The vehicle window glass assembly 100 provided in this application embodiment cleans the surface of the glass body 1 by providing a transducer 21 on the inner surface 101 of the glass body 1 and using the transducer 21 to excite the glass body 1. This cleaning method is not only highly efficient but also produces good cleaning results. Furthermore, by providing the transducer 21 on the inner surface 101 of the glass body 1 and performing targeted cleaning on specific areas of the glass body 1, energy consumption is effectively saved.
[0057] In some embodiments, transducer 21 is an ultrasonic transducer. The ultrasonic transducer outputs ultrasonic waves. Ultrasonic waves are essentially a type of high-frequency mechanical vibration energy. As an example, ultrasonic waves are mechanical vibration energy with a frequency higher than 20,000 Hz. By utilizing the high-frequency vibration characteristics of ultrasonic waves, the efficiency and cleaning effect of cleaning the glass body 1 can be effectively improved. Optionally, the ultrasonic transducer is a piezoelectric transducer or a magnetostrictive transducer. A piezoelectric transducer converts electrical energy into mechanical vibration through the piezoelectric effect, while a magnetostrictive transducer converts electrical energy into mechanical vibration through the magnetostrictive effect. The shape of the ultrasonic transducer can be set according to requirements, for example, it can be elliptical or elongated.
[0058] In some implementations, please refer to Figure 2 and Figure 4 The cleaning device 2 also includes a first adhesive layer 22, which is disposed between the transducer 21 and the glass body 1. The transducer 21 is bonded to the glass body 1 through the first adhesive layer 22, thereby achieving a tight attachment of the transducer 21 to the glass body 1. This allows the vibrational mechanical energy output by the transducer 21 to be effectively transmitted to the glass body 1 after passing through the first adhesive layer 22, causing the glass body 1 to vibrate synchronously. It should be noted that the transducer 21 and the first adhesive layer 22 can be directly or indirectly bonded, but the glass body 1 and the first adhesive layer 22 are directly bonded.
[0059] In some implementations, please refer to Figure 2 The thickness of the first adhesive layer 22 is greater than or equal to 100 μm. This configuration ensures that the adhesive joint of the first adhesive layer 22 can withstand at least 1 million vibrations. For example, the thickness of the first adhesive layer 22 can be 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, 160 μm, 170 μm, 180 μm, 190 μm, or 200 μm.
[0060] In some implementations, please refer to Figures 5 to 8The cleaning device 2 also includes an amplitude modulator 23, which is disposed between the transducer 21 and the glass body 1, and is in direct contact with the transducer 21. The amplitude modulator 23 is an amplitude amplification device used to amplify the amplitude of the mechanical vibration generated by the transducer 21, and the amplified mechanical vibration is further transmitted to the glass body 1, causing the glass body 1 to vibrate. The mechanical vibration generated by the transducer 21 is amplified by the amplitude modulator 23, which can improve the energy output efficiency and cleaning effect. As an example, the amplitude modulator 23 is stacked with the transducer 21, with the amplitude modulator 23 located between the transducer 21 and the glass body 1, and the first adhesive layer 22 is disposed between the amplitude modulator 23 and the glass body 1. That is, the transducer 21, the amplitude modulator 23, the first adhesive layer 22 and the glass body 1 are distributed in sequence, the amplitude modulator 23 is directly bonded to the first adhesive layer 22, and the transducer 21 is indirectly bonded to the first adhesive layer 22 through the amplitude modulator 23.
[0061] In some implementations, please refer to Figures 1 to 8 The window glass assembly 100 also includes a base 3, which is supported on the inner surface 101 of the glass body 1. The cleaning device 2 is disposed within the base 3 and clamped between the glass body 1 and the base 3. The base 3 presses the cleaning device 2 onto the surface of the glass body 1, thus fixing the cleaning device 2 in place. As an example, the cleaning device 2 includes a transducer 21 and an amplitude modulator 23, and the base 3 presses and fixes the transducer 21 and the amplitude modulator 23 firmly onto the glass body 1.
[0062] In some implementations, please refer to Figure 8 The base 3 includes a cylindrical body 31 and a baffle 32 disposed within the cylindrical body 31. The cylindrical body 31 is supported on the inner surface 101 of the glass body 1. The cylindrical body 31 and the baffle 32 define a receiving cavity 302. The cleaning device 2 is disposed within the receiving cavity 302 and is clamped between the glass body 1 and the baffle 32. With the above arrangement, the cleaning device 2 is housed within the receiving cavity 302 of the base 3, and the base 3 covers the cleaning device 2. In addition to fixing the cleaning device 2, the base 3 can also protect the base 3. As an example, the cleaning device 2 includes a transducer 21, an amplitude modulator 23, and a first adhesive layer 22, all of which are disposed within the receiving cavity 302 of the base 3.
[0063] In some implementations, please refer to Figure 8 The window glass assembly 100 also includes a sealing ring 4, which surrounds the cleaning device 2 and is clamped between the base 3 and the glass body 1. The sealing ring 4 seals the gap between the base 3 and the glass body 1, so that when the transducer 21 drives the glass body 1 to vibrate, fine dust on the glass body 1 is less likely to enter the base 3, thus playing a dustproof role. As an example, the sealing ring 4 is clamped between the cylinder 31 of the base 3 and the glass body 1.
[0064] In some implementations, please refer to Figure 8 The window glass assembly 100 also includes a bracket 5, which is connected to the base 3. The bracket 5 is also used to connect to the center console 220 on the vehicle 200. The bracket 5 allows the base 3 to be fixed to the center console 220, improving the installation stability of the base 3. It should be noted that the bracket 5 is not limited to connecting to the center console 220 of the vehicle 200. In other embodiments, the installation position of the bracket 5 can be set according to specific needs. For example, the window glass assembly 100 can be applied to the vehicle 200, and the cleaning device 2 can be correspondingly arranged near the rearview mirror. The bracket 5 is used to connect to the rearview mirror or components near the rearview mirror.
[0065] In some implementations, please refer to Figure 8 The bracket 5 is L-shaped and includes a first sub-part 51 extending along a first direction and a second sub-part 52 extending along a second direction, the first and second directions intersecting. The first sub-part 51 is connected to the base 3, and the second sub-part 52 is used to connect to the center console 220. This arrangement facilitates the installation of the bracket 5. As an example, there are two brackets 5, which are spaced apart and distributed on the left and right sides of the base 3 to provide stable support for the base 3. Optionally, the bracket 5 is connected to the base 3 and the center console 220 by fasteners 53. As an example, the fasteners 53 are bolts, and there are multiple bolts, wherein the first sub-part 51 is connected to the base 3 by bolts, and the second sub-part 52 is also used to connect to the center console 220 by bolts. Of course, in other embodiments, the first sub-part 51 can be welded to the base 3, and the second sub-part 52 can be welded to the center console 220.
[0066] In some implementations, please refer to Figure 2 and Figure 8A first through-hole 201 is provided through the cleaning device 2. By providing the first through-hole 201, a portion of the glass body 1 can be exposed to the outside of the cleaning device 2 through the first through-hole 201, while this portion is surrounded by the cleaning device 2. This area can be cleaned by the transducer 21. Thus, when the window glass assembly 100 is installed on the vehicle 200, the first through-hole 201 can be configured to correspond to the optical sensor 210 (e.g., lidar) on the vehicle 200. The first through-hole 201 is used to avoid the signal acquisition optical path of the optical sensor 210, so that the optical sensor 210 can acquire information through the cleaned area on the glass body 1, reducing the interference of dust, frost, etc. on the glass body 1 on the detection results of the optical sensor 210. As an example, the cleaning device 2 includes a transducer 21, an amplitude modulator 23, and a first adhesive layer 22, with the first through-hole 201 penetrating through the transducer 21, the amplitude modulator 23, and the first adhesive layer 22. Of course, in other embodiments, the first through hole 201 may not be provided on the cleaning device 2. In this case, the optical sensor 210 can be aligned with the outer area of the cleaning device 2 and aligned with the first area 104 of the glass body 1.
[0067] In some implementations, please refer to Figure 2 and Figure 8 The window glass assembly 100 also includes a base 3 covering the cleaning device 2. A second through-hole 301 is provided through the base 3, corresponding to the first through-hole 201. The second through-hole 301 is provided to avoid obstruct the signal acquisition optical path of the optical sensor 210, and also to allow wiring to pass through, thereby supplying power to electrical components in the cleaning device 2, such as the transducer 21 or the amplitude modulator 23. As an example, the second through-hole 301 is provided through a baffle 32.
[0068] In some implementations, please refer to Figure 8 The window glass assembly 100 also includes a buffer ring 6, which is disposed at the edge of the outer surface 102 of the glass body 1 and extends circumferentially along the glass body 1. The buffer ring 6 is used to buffer the force between the glass body 1 and the external structure in contact with it, especially during the operation of the transducer 21, the buffer ring 6 can reduce the risk of collision between the glass body 1 and the external structure. As an example, the window glass assembly 100 is used to fix the vehicle frame 200 to the contact surface where the window glass assembly 100 makes rigid contact, the buffer ring 6 can make the mechanical energy of vibration of the glass body 1 caused by the transducer 21 less likely to affect the frame.
[0069] In some implementations, please refer to Figures 1 to 4The glass body 1 includes a first body 11 and a first glass sheet 12. A third through hole 103 is provided through the first body 11. The first glass sheet 12 is embedded in the third through hole 103. A transducer 21 is disposed on the inner surface of the first glass sheet 12 to clean it. When water mist, raindrops, dust, etc. adhere to the glass body 1, the transducer 21 is activated. The transducer 21 converts electrical energy into vibrational mechanical energy and transmits it to the first glass sheet 12. The first glass sheet 12 vibrates. The high-frequency and minute vibration causes cavitation or atomization on the surface of the first glass sheet 12, making it difficult for water mist, raindrops, dust, etc. to adhere to the surface of the first glass sheet 12, and thus dissipating from the air, thereby cleaning the first glass sheet 12. This method mainly uses the transducer 21 to apply vibration to the independent first glass sheet 12, thereby greatly saving energy consumption. It should be noted that the first body 11 can be a single-layer structure or a multi-layer structure. The shape of the third through hole 103 can be set according to requirements, such as a circle, rectangle or triangle. The shape of the first glass plate 12 is adapted to the shape of the third through hole 103, but the size of the first glass plate 12 is slightly smaller than the size of the third through hole 103, so as to ensure that the first glass plate 12 can be put into the third through hole 103.
[0070] In some implementations, please refer to Figure 2 The glass body 1 also includes a second adhesive layer 13 disposed within the third through hole 103. The second adhesive layer 13 is located between the first glass sheet 12 and the first body 11 to bond the first glass sheet 12 to the first body 11 and seal the gap between the first glass sheet 12 and the first body 11. The second adhesive layer 13 flexibly connects the first glass sheet 12 and the first body 11. The mechanical vibration energy output by the transducer 21 is transmitted to the second adhesive layer 13 through the first glass sheet 12, and the mechanical vibration energy is weakened at the second adhesive layer 13. In this way, the transducer 21 only cleans the first glass sheet 12. In addition, the second adhesive layer 13 fills the space between the first glass sheet 12 and the first body 11, which can also prevent moisture, dust and other impurities from entering.
[0071] In some implementations, please refer to Figure 3 The thickness of the first glass sheet 12 is less than the thickness of the first body 11. By thinning the first glass sheet 12, the transducer 21 applies vibration to the thinner first glass sheet 12, effectively reducing energy consumption and improving the cleaning effect on the first glass sheet 12.
[0072] In some implementations, please refer to Figure 2 and Figure 3The first body 11 has a multi-layer structure, comprising an inner glass layer 111, an intermediate interlayer 112, and an outer glass layer 113 stacked sequentially. The intermediate interlayer 112 bonds the inner glass layer 111 and the outer glass layer 113. A third through-hole 103 penetrates the inner glass layer 111, the intermediate interlayer 112, and the outer glass layer 113. A first glass sheet 12 is embedded in the outer glass layer 113, and the thickness of the first glass sheet 12 is less than or equal to the thickness of the outer glass layer 113. Understandably, the depth of the third through-hole 103 is comparable to the thickness of the first body 11, therefore the depth of the third through-hole 103 is greater than the thickness of the first glass sheet 12. When the transducer 21 is configured to be disposed on the inner surface of the first glass sheet 12, at least a portion of the cleaning device 2 extends into the third through-hole 103, which can limit the movement of the cleaning device 2.
[0073] Secondly, please refer to the figure. Figure 9 and Figure 10 This application provides a vehicle 200, including the aforementioned window glass assembly 100.
[0074] The vehicle 200 includes the aforementioned window glass assembly 100, and therefore the vehicle 200 has all the beneficial effects of the aforementioned window glass assembly 100, which will not be elaborated here.
[0075] In some implementations, please refer to Figure 9 and Figure 10 The vehicle 200 includes an optical sensor 210 disposed within the vehicle 200. The optical sensor 210 is configured to acquire environmental information outside the vehicle 200 through a localized area on a glass body 1 that is cleaned by a transducer 21. Specifically, while the optical sensor 210 is installed inside the vehicle 200, it is used to acquire environmental information outside the vehicle 200. The optical sensor 210 relies on light passing through the glass body 1, and more specifically, through a localized area on the glass body 1 cleaned by the transducer 21, to acquire information about the external environment of the vehicle 200. This method reduces interference from dust, rain, or frost on the glass body 1 on the acquisition process of the optical sensor 210, improving the reliability of the detection results. Optionally, the optical sensor 210 includes at least one of a camera and a lidar sensor.
[0076] As an example, the vehicle 200 may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific limitations in this regard.
