Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an information acquisition component, a pillar assembly, and a windshield assembly. Background Technology

[0002] With the rapid development of new energy vehicles in recent years, information collection devices such as cameras have been applied to vehicles to provide information about the external environment and thus ensure driving safety. Cameras can be installed on the windshield, rear windshield, B-pillar, etc. When a vehicle is in inclement weather such as rain or frost, temperature changes in the external environment can cause fogging on the surface of the camera mounting hardware, such as the glass, preventing the information collection device from acquiring information about the external environment.

[0003] For cameras mounted on the windshield or rear windshield, traditional gasoline-powered vehicles can alleviate fogging issues through the air conditioning, but this is not an effective way to defrost them. Currently, defrosting can be achieved by heating the mounting components, but this method suffers from low heating efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an information acquisition component, a pillar assembly, and a windshield assembly. The information acquisition component has high heating efficiency and can quickly remove fog or frost from the mounting components.

[0005] This application embodiment provides an information acquisition component, which includes:

[0006] The mounting component has a viewing area, which is used to provide a window for the information acquisition device to collect information.

[0007] The heating wire is located on the side of the mounting component facing the information acquisition device and surrounds the viewing window area. The sheet resistance of the heating wire is 20 milliohms / □ to 1000 milliohms / □.

[0008] The information acquisition component provided in this application embodiment, on the one hand, avoids the problem of the heating wire interfering with the information acquisition device by surrounding the viewing window area, and at the same time reduces the impact of the light distortion of the heating wire on the information acquisition device, thus ensuring vehicle driving safety. On the other hand, by increasing the sheet resistance Rs of the heating wire to 20 milliohms / □ to 1000 milliohms / □, while keeping the power P of the heating wire constant, the length of the heating wire can be shortened, thereby reducing the number of times the heating wire surrounds the viewing window area. This makes the heat generated by the heating wire more concentrated around the viewing window area, and the heat from the heating wire is transferred to the viewing window area more quickly, thereby improving the heating efficiency of the heating wire. This enables the information acquisition component to quickly remove fog or frost from the installed parts.

[0009] In one possible implementation, the perimeter of the viewing area is C, the length of the heating wire is L, and L / C = 1 to 8.

[0010] In one possible implementation, L / C = 1 to 2.

[0011] In one possible implementation, the width of the heating wire is 1.0 mm to 20 mm.

[0012] In one possible implementation, the heating wire is made of silver paste, which includes an organic carrier and silver powder dispersed in the organic carrier.

[0013] In one possible implementation, the silver paste comprises 5%–20% organic carrier and 5%–70% silver powder by weight. By controlling the silver powder content in the silver paste to be between 5% and 70%, the amount of silver powder in the silver paste is reduced, thereby increasing the sheet resistance Rs of the prepared heating wire while ensuring the adhesion and weather resistance of the heating wire on the mounting component.

[0014] In one possible implementation, the silver paste further includes an insulating additive dispersed in an organic carrier. The insulating additive forms an insulating layer between the silver powder particles, hindering electron conduction, thereby increasing the sheet resistance Rs of the heating wire.

[0015] In one possible implementation, the insulating additive is nano-silica with a particle size of 50 nm to 100 nm, and the mass fraction of nano-silica in the silver paste is 2% to 5%. By adding nano-silica, a nanoscale insulating barrier can be formed between the silver powder particles, thereby improving the sheet resistance Rs of the heating wire.

[0016] In one possible implementation, the silver paste further includes a metal or compound, the metal having a higher resistance than the silver powder. The sheet resistance of the heating wire formed before the addition of the compound is Rs1, and the sheet resistance of the heating wire formed after the addition of the compound is Rs2, where Rs2 > Rs1. The mixing of these metals or compounds with the silver powder alters the conductivity mechanism of the silver paste, thereby increasing the overall resistance of the heating wire.

[0017] In one possible implementation, the thickness of the heating wire is 1μm to 20μm, which on the one hand helps to increase the sheet resistance Rs of the heating wire, and on the other hand ensures the stable conductivity of the heating wire.

[0018] In one possible implementation, the information acquisition component further includes a first shielding layer, which is disposed on the surface of the mounting member facing the information acquisition device and surrounds the viewing window area, with the heating wire disposed on the side of the first shielding layer away from the mounting member.

[0019] In one possible implementation, the information acquisition component further includes a power supply element and a connector, wherein the power supply element is electrically connected between the heating wire and the connector, and the connector is used for electrical connection to a power source.

[0020] The silver paste contains ≤70% silver powder by mass, and the power supply element is made of conductive adhesive. When the silver powder content in the silver paste is ≤70%, there will be adhesion issues between the heating wire and the power supply element, making it difficult to use solder for power supply. By using conductive adhesive for the power supply element, the adhesion between the heating wire and the power supply element can be improved, preventing the power supply element from detaching.

[0021] In one possible implementation, the information acquisition component further includes a second shielding layer, a connector, and an accessory. The second shielding layer is located on the side of the heating wire facing away from the mounting component and covers the heating wire. The connector is located on the side of the second shielding layer facing away from the mounting component and connects the second shielding layer and the accessory. By covering the heating wire with a second shielding layer, the silver paste can be prevented from undergoing qualitative changes, thereby improving the service life and heating effect of the heating wire.

[0022] In one possible implementation, the heating wire includes a first section, a middle section, and a second section. The middle section connects the first and second sections and is arranged around the viewing area. The line width of the first section is greater than that of the middle section, and the line width of the second section is greater than that of the middle section. This results in the power of the middle section being greater than that of the first section and the power of the middle section being greater than that of the second section. This allows the power of the heating wire to be mainly concentrated in the middle section surrounding the viewing area, concentrating more power in the heating wire around the viewing area. Consequently, the heat generated by the heating wire is more concentrated around the viewing area, and the heat is transferred to the viewing area more quickly, thereby improving the heating efficiency of the heating wire.

[0023] In one possible implementation, the middle section includes multiple turns of heating wires, all of which are arranged around the viewing window area.

[0024] The line widths of the multi-turn heating segments are all equal, or the multi-turn heating segments include an Nth turn and an (N+m)th turn. The Nth and (N+m)th turns are arranged sequentially in a direction away from the viewing window area. The line width of the Nth turn is less than the line width of the (N+m)th turn, where N ≥ 1 and N is a natural number, and m > 0 and m is a natural number. By setting the line width of the Nth turn to be less than that of the (N+m)th turn, the heating segments closer to the viewing window area are made thinner, resulting in greater power in these segments. This concentrates more power in the heating wire around the viewing window area, ensuring that the heat generated by the heating wire is more concentrated around the viewing window area, and that heat is transferred to the viewing window area more quickly, further improving the heating efficiency of the heating wire.

[0025] In one possible implementation, the information acquisition component includes a heating component, which includes a heating wire, a first insulating layer, a second insulating layer, and a connector. The heating wire is sandwiched between the first insulating layer and the second insulating layer. The first insulating layer is connected to the mounting component, the second insulating layer is located on the side of the first insulating layer away from the mounting component, and the connector is electrically connected to the heating wire.

[0026] The first insulation layer has a first clearance opening that penetrates the first insulation layer along its thickness direction. The second insulation layer has a second clearance opening that penetrates the second insulation layer along its thickness direction. The second clearance opening connects with the first clearance opening to form a clearance window, with the viewing area exposed relative to the clearance window. By clamping the heating wire between the first and second insulation layers to form a single unit, oxidation caused by contact with air is avoided, ensuring the lifespan and heating effect of the heating wire. Furthermore, by integrating the connector and heating wire into a single heating assembly, it can be adhered to the mounting component using an adhesive layer, enabling defrosting and defogging of the mounting component. This method is convenient and offers higher installation efficiency compared to using a separate heating wire.

[0027] This application embodiment also provides a column assembly, including a column and the above-mentioned information acquisition component, with the mounting component disposed on the column.

[0028] This application also provides a windshield assembly, including the above-mentioned information acquisition component, with the windshield as the mounting component. Attached Figure Description

[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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Please see Figure 1 and Figure 2 , Figure 1 This is a cross-sectional structural diagram of the information acquisition component 1 provided in the embodiments of this application. Figure 2 for Figure 1 The diagram shows the assembly structure in which the heating wire 700 in the information acquisition component 1 is arranged in a wrap-around manner on the mounting component 100.

[0052] The information acquisition component 1 provided in this application embodiment can be applied to a vehicle. The vehicle includes a frame and the information acquisition component 1, which is mounted on the frame. The information acquisition component 1 includes a mounting component 100, a bracket 300, and an information acquisition device 500.

[0053] Specifically, the mounting component 100 has a viewing area S1 and an edge area P1, with the edge area P1 surrounding the viewing area S1. The viewing area S1 serves as a window for the information acquisition device 500 to acquire information. The viewing area S1 has a light-transmitting effect; however, this does not mean that all types of light can pass through the viewing area S1 without obstruction or with low obstruction. In one embodiment, the viewing area S1 has high transmittance for visible light; in another embodiment, the viewing area S1 has high obstruction for visible light but high transmittance for infrared light. For example, the wavelength of visible light is 380nm to 780nm, and the wavelength of infrared light is 800nm ​​to 2100nm.

[0054] Mounting component 100 can be installed on a vehicle pillar, including but not limited to the A-pillar, B-pillar, C-pillar, and D-pillar. In this case, the pillar assembly includes the pillar and the information acquisition component 1, which forms part of the pillar assembly. The mounting component 100 can be made of glass or other materials such as plastic; this application does not limit this. In other embodiments, mounting component 100 can also be a windshield, such as the front or rear windshield of a vehicle. In this case, the windshield assembly includes the information acquisition component 1, which forms part of the windshield assembly. Mounting component 100 is made of glass. It is understood that when mounting component 100 is made of glass, the glass provides high visible light transmittance and good protective performance. It should be noted that the aforementioned "glass" includes tempered glass and laminated glass.

[0055] In one or more embodiments, the bracket 300 is mounted on one side of the mounting member 100 along the thickness direction and forms a receiving cavity with the mounting member 100. The information acquisition device 500 is disposed on one side of the mounting member 100 along the thickness direction and is located within the receiving cavity.

[0056] In one or more embodiments, the bracket 300 is mounted on one side of the mounting member 100 along the thickness direction, the information acquisition device 500 is disposed on the side of the bracket 300 away from the mounting member 100, the bracket 300 is provided with an opening, and the information acquisition head of the information acquisition device 500 is disposed in the opening and is disposed opposite to the viewing window area S1.

[0057] The information acquisition device 500 can acquire information from the outside of the vehicle through the viewing area S1 of the mounting member 100. For example, the information acquisition device 500 can be a camera with functions such as surround view, face recognition, driver assistance, and sentry mode.

[0058] Temperature variations in the external environment can cause fogging on the surface of the mounting component 100. Additionally, rain and frost can prevent the information acquisition device 500 from acquiring external image information, thus hindering the proper functioning of facial recognition, driver assistance, and other functions, impacting driving safety. For example, if the mounting component 100 is located on the B-pillar of the vehicle, the fog and frost cannot be cleared by the vehicle's internal air conditioning system, resulting in a loss of information acquisition capability for the information acquisition device 500.

[0059] To address the aforementioned issues, the information acquisition component 1 provided in this embodiment further includes a heating wire 700 and a power supply. The heating wire 700 is disposed on the side of the mounting component 100 facing the information acquisition device 500. The power supply is electrically connected to the heating wire to heat it, thereby removing fog and frost from the surface of the mounting component 100 using the heat generated by the heating wire 700. This prevents fog and frost from affecting the information acquisition by the information acquisition device 500, ensuring vehicle driving safety. For example, the heating wire 700 is made of silver paste. In this embodiment, the heating wire 700 is prepared by printing silver paste.

[0060] Depending on the arrangement of the heating wire 700 on the mounting member 100, it can be divided into a horizontal type and a surrounding type. In this embodiment, the heating wire 700 is arranged in a surrounding manner on the mounting member 100. Specifically, the heating wire 700 is located on the edge area P1 of the mounting member 100 and surrounds the viewing window area S1. The heating wire 700 includes a first segment 710, a middle segment 730, and a second segment 750. The middle segment 730 connects the first segment 710 and the second segment 750 and surrounds the viewing window area S1. The first segment 710 is used to electrically connect to the positive terminal of the power supply, and the second segment 750 is used to electrically connect to the negative terminal of the power supply, so that the heating wire 700 is electrically connected to the power supply, thereby enabling the heating wire 700 to generate heat. The middle segment 730 includes at least one ring of heating wire segment 701, and each ring of heating wire segment 701 surrounds the viewing window area S1.

[0061] See also Figure 3 , Figure 3 This is a schematic diagram illustrating a heating wire 700 arranged horizontally on the mounting member 100 in another embodiment. In other embodiments, when the heating wire 700 is arranged horizontally on the mounting member 100, at least a portion of the heating wire 700 is located within the viewing area S1 of the mounting member 100. The applicant has studied and analyzed the advantages and disadvantages of arranging the heating wire 700 in a wraparound manner and a horizontally traversing manner on the mounting member 100, and the summary is shown in Table 1.

[0062] Table 1 shows the advantages and disadvantages of using a wraparound or transverse arrangement for the heating wire 700 on the mounting component 100.

[0063]

[0064] See also Figure 4 , Figure 4 This is a schematic diagram illustrating the principle behind optical distortion caused by silver paste. Among them, Figure 4 (a) shows a schematic diagram of the glass mounting component 100 before it is bent and formed at high temperature. Figure 4 (b) shows a schematic diagram of the glass mounting component 100 after it has been bent and formed at high temperature.

[0065] Figure 4 Taking the example of the heating wire 700 being installed in a horizontal manner on the mounting component 100, the reason why the heating wire 700 made of silver paste will cause optical distortion is because silver reflects heat (such as along the...). Figure 4 (a) The direction of the dashed arrow in the image reflects heat, causing the local temperature T1 of the edge area P1 where the silver paste is printed to be lower than the temperature T2 of the unprinted window area S1. This local temperature difference leads to minute unevenness on the glass surface. Similar to the principle of a concave-convex lens, this unevenness causes defects such as ghosting and distortion in the image recognized by the information acquisition device 500. Figure 5 As shown, Figure 5 This is a schematic diagram showing different types of distorted images captured by the information acquisition device 500 when optical distortion occurs on the heating line 700. Among them, Figure 5 In the middle, (a) indicates barrel deformation, and (b) indicates needle pad distortion.

[0066] Combining Table 1 and Figure 4 Compared to the horizontal arrangement, when the heating wire 700 is arranged in a wraparound manner on the mounting component 100, on the one hand, the heating wire 700 will not enter the viewing window area S1 to interfere with the information acquisition device 500's information acquisition, thus avoiding the problem that the heating wire 700 would enter the viewing window area S1 to interfere with the information acquisition device 500's information acquisition when the heating wire 700 is arranged in a horizontal arrangement on the mounting component 100. On the other hand, the light distortion caused by the heating wire 700 is small, which is conducive to improving the acquisition effect of the information acquisition device 500.

[0067] Refer to Table 2. Figure 6 and Figure 7 Table 2 compares the heating effect when the heating wire 700 is installed in the mounting part 100 in a wrap-around manner and a cross-through manner. Figure 6 Simulation diagram of hot spot temperature and defrosting efficiency on mounting component 100 when heating wire 700 is arranged in a transverse manner. Figure 6 (a) shows a simulation diagram of the hot spot temperature on mounting component 100. Figure 6Figure (b) shows the simulation diagram of the defrosting efficiency of the mounting part 100 when heated by the heating line 700 for 6 min, 7 min, 8 min and 9 min respectively. Figure 7 Simulation diagram of hot spot temperature and defrosting efficiency on mounting component 100 when heating wire 700 adopts a wraparound design. Figure 7 (a) shows a simulation diagram of the hot spot temperature on mounting component 100. Figure 7 Figure (b) shows the simulation diagram of the defrosting efficiency of the mounting part 100 after heating on the heating line 700 for 12 min and 20 min respectively.

[0068] Table 2 compares the heating effects of heating wire 700 installed on mounting component 100 using a wraparound and transverse configuration.

[0069]

[0070] Combined with Table 2, Figure 6 and Figure 7 When the heating wire 700 is arranged in a wraparound manner, the defrosting rate of the viewing area S1 reaches 96.2385% after 6 minutes of heating. However, when the heating wire 700 is arranged in a wraparound manner, the defrosting rate of the viewing area S1 only reaches 42.1176% after 20 minutes of heating. It is evident that the heating efficiency is lower when the heating wire 700 is arranged in a wraparound manner on the mounting component 100 compared to the horizontal arrangement. The reasons are as follows: When the heating wire 700 is arranged in a wraparound manner, firstly, the heat generated by the heating wire 700 cannot directly reach the viewing area S1 and needs to be transferred to the viewing area S1 through heat transfer, thus the heating efficiency of the central viewing area S1 is lower. Secondly, although the heating wire 700 surrounds the viewing area S1 with multiple rings of heating wire segments 701, only the one or two rings of heating wire segments 701 closest to the viewing area S1 are actually effective. When the series current is equal, the longer the heating wire 700 is, the more power will be diverted to the heating wire segment 701 that is far away from the viewing window area S1. This causes the heating efficiency of the heating wire 700 to be wasted on the useless heating wire segment 701, thus preventing the power of the heating wire 700 from being concentrated on the one or two rings of heating wire segments 701 around the viewing window area S1, resulting in low heating efficiency of the heating wire 700.

[0071] Referring to Tables 1 and 2, to avoid optical distortion of the heating wire 700 in the viewing window area S1 of the mounting component 100, the heating wire 700 needs to be arranged in a wraparound manner on the mounting component 100. However, this wraparound arrangement results in low heating efficiency of the heating wire 700. Therefore, in the information acquisition component 1 provided in this application embodiment, the heating wire 700 is arranged in a wraparound manner on the mounting component 100, and the sheet resistance of the heating wire 700 is limited to 20 milliohms / □ to 1000 milliohms / □. This ensures that optical distortion of the heating wire 700 does not affect the information acquisition device 500's acquisition of information through the viewing window area S1, and also improves the heating efficiency of the heating wire 700. This allows the heating wire 700 to quickly remove fog or frost from the viewing window area S1, preventing the information acquisition device 500 from being obstructed by water mist, rain, or frost, enabling it to acquire information at any time and ensuring vehicle driving safety. The heating wire 700 provided in this application embodiment will be analyzed and explained in detail below. In this embodiment, the sheet resistance of the heating wire 700 is measured using the national standard GB / T 17473.3-2008 (Test Method for Sheet Resistance of Precious Metal Paste for Microelectronics Technology).

[0072] The power of the heating wire 700 affects the hot spot temperature of the mounting component 100 and the efficiency of defrosting and defogging the mounting component 100. The power P of the heating wire 700 satisfies:

[0073]

[0074] Where U represents the voltage applied across the heating wire 700, and R represents the resistance of the heating wire 700. The resistance R of the heating wire 700 satisfies:

[0075]

[0076] Where Rs represents the sheet resistance of heating wire 700, L represents the length of heating wire 700, and W represents the line width of heating wire 700.

[0077] Combining the analysis of formulas 1 and 2, it can be seen that the voltage U is usually the client input, and U is a fixed value. The applicant's research and analysis found that, while keeping the power P of the heating wire 700 constant, by increasing the sheet resistance Rs of the heating wire 700, the length of the heating wire 700 can be shortened. This avoids the problem of excessive turns in the heating wire segment 701 far from the viewing window area S1 when the heating wire 700 is long, which would lead to excessive power waste in the heating wire 700. As a result, the useful power in the heating wire 700 is concentrated around the viewing window area S1, thereby improving the heating efficiency of the heating wire 700.

[0078] For example, when the sheet resistance Rs of the heating wire 700 is 3 milliohms / □ to 20 milliohms / □, the length of the heating wire 700 is usually as high as 850mm to 1500mm, resulting in significant power waste. However, in this embodiment, by increasing the sheet resistance Rs of the heating wire 700 to 20 milliohms / □ to 1000 milliohms / □, the length of the heating wire 700 can be shortened while maintaining the same power P. Since the perimeter of the edge contour of the same viewing area S1 is fixed, the shorter the length of the heating wire 700, the fewer turns of the heating wire segment 701 around the viewing area S1. This facilitates a more concentrated power distribution around the viewing area S1, thereby improving the heating efficiency of the heating wire 700. For example, the perimeter of the viewing area S1 is C, and the length of the heating wire 700 is L, where L / C = 1 to 8, meaning the number of turns of the heating wire 700 around the viewing area S1 is approximately 1 to 8. For example, the length L of the heating wire 700 is < 850 mm. Here, the perimeter C of the viewing area S1 refers to the perimeter of the outer contour of the viewing area S1, that is, the perimeter of the contour of the viewing area S1 facing the heating wire 700. The length L of the heating wire 700 refers to the length of the inner contour of the heating wire 700, that is, the length of the contour of the heating wire 700 facing the viewing area S1. (See also...) Figure 8 and Figure 9 , Figure 8 for Figure 2 The diagram shows a new design for the heating wire 700 in the assembly structure shown. Figure 9 for Figure 8 The diagram shows the structure of part A in another embodiment of the assembly structure shown. Figure 9 In (a) heating wire 700, the first segment 710 and the second segment 750 adopt a rounded chamfer design; in (b) heating wire 700, the first segment 710 and the second segment 750 adopt a right-angle chamfer design; and in (c) heating wire 700, the first segment 710 and the second segment 750 adopt a rounded design. Figure 8 As shown, the inner contour of the heating wire 700 includes a starting point C1 and an ending point C2. The length L of the heating wire 700 refers to the length from the starting point C1 to the ending point C2 of the inner contour of the heating wire 700. Figure 9 As shown in (a), the starting point C1 of the inner contour of the heating line 700 is the connection point of the straight line portion connecting to the rounded chamfer in the inner contour of the first segment 710, and the ending point C2 is the connection point of the straight line portion connecting to the rounded chamfer in the inner contour of the second segment 750. Figure 9 As shown in (b), the starting point C1 of the inner contour of the heating line 700 is the connection point of the straight line portion connecting to the right-angle chamfer in the inner contour of the first segment 710, and the ending point C2 is the connection point of the straight line portion connecting to the right-angle chamfer in the inner contour of the second segment 750. Figure 9As shown in (c), the starting point C1 of the inner contour of the heating line 700 is the connection point of the straight line part that connects to the arc in the inner contour of the first segment 710, and the ending point C2 is the connection point of the straight line part that connects to the arc in the inner contour of the second segment 750.

[0079] In some embodiments, L / C = 1 to 2, meaning the heating wire 700 around the viewing window area S1 has approximately one turn. For example... Figure 8 In the heating wire 700 shown, L / C = 1.48. In other embodiments, L / C may also be 1.1, 1.2, 1.4, 1.6, 1.8, 1.9, 2, etc., and this application does not limit this.

[0080] Furthermore, according to Formula 2, if the line width W of the heating wire 700 is too large, the resistance of the heating wire 700 will decrease, resulting in excessive power and overheating of the heating wire 700. Therefore, when the sheet resistance Rs of the heating wire 700 is 3 milliohms / □ to 20 milliohms / □, the line width W of the heating wire 700 is usually designed to be relatively thin, ranging from 0.4mm to 1.0mm. However, since the sheet resistance Rs of the heating wire 700 in this embodiment is increased to 20 milliohms / □ to 1000 milliohms / □, the line width W of the heating wire 700 can be increased without causing the heating wire 700 to overheat, while keeping the power P of the heating wire 700 constant. For example, the line width W of the heating wire 700 is 1.0mm to 20mm.

[0081] The information acquisition component 1 provided in this application embodiment, on the one hand, avoids the problem of the heating wire 700 interfering with the information acquisition device 500's information acquisition by entering the window area S1 by setting the heating wire 700 around the window area S1, and at the same time reduces the impact of the light distortion of the heating wire 700 on the information acquisition device 500, thus ensuring the vehicle's driving safety. On the other hand, by increasing the sheet resistance Rs of the heating wire 700 to 20 milliohms / □ to 1000 milliohms / □, while keeping the power P of the heating wire 700 unchanged, the length of the heating wire 700 can be shortened, thereby reducing the number of times the heating wire 700 wraps around the window area S1. This makes the heat generated by the heating wire 700 more concentrated around the window area S1, and the heat from the heating wire 700 is transferred to the window area S1 faster, thereby improving the heating efficiency of the heating wire 700. This enables the information acquisition component 1 to quickly remove fog or frost from the mounting component 100.

[0082] Taking the heating wire 700 made of silver paste as an example, the silver paste includes an organic carrier and silver powder dispersed in the organic carrier. The organic carrier ensures the flowability and formability of the silver paste during screen printing. Exemplarily, the organic carrier includes, but is not limited to, at least one of a solvent, resin binder, dispersant, thickener, defoamer, and coupling agent. The silver powder generally has a purity ≥99.9% and is used to provide electrical conductivity. In this embodiment, the silver paste also includes glass powder, which forms a chemical bond with the mounting component 100 of the glass substrate after sintering, ensuring the adhesion of the heating wire 700 to the mounting component 100 and addressing sintering issues. To improve the sheet resistance Rs of the heating wire 700 from 20 milliohms / □ to 1000 milliohms / □, thereby improving the heating efficiency of the heating wire 700, the applicant has researched and provided the following methods:

[0083] I. Through research and analysis, the applicant discovered that silver powder is the main conductive component of silver paste. The higher the silver powder content in the silver paste, the better the conductivity and the lower the sheet resistance of the heating wire 700. By controlling the silver powder content and reducing its content in the silver paste, the sheet resistance Rs of the prepared heating wire 700 can be increased. However, if the silver powder content is too low, it will affect the adhesion of the silver paste to the mounting component 100, the weather resistance of the silver paste, and other properties. Therefore, it is necessary to appropriately reduce the proportion of silver powder in the silver paste.

[0084] The applicant's research found that when the sheet resistance Rs of the heating wire 700 is 3 milliohms / □ to 20 milliohms / □, the mass fraction of silver powder in the silver paste is typically 70% to 90%. In this application's embodiments, by controlling the mass fraction of silver powder in the silver paste to 5% to 70%, the sheet resistance Rs of the heating wire 700 can be achieved to be between 20 milliohms / □ and 1000 milliohms / □, while ensuring the adhesion and weather resistance of the heating wire 700 on the mounting component 100. Specifically, in some embodiments, the silver paste, by mass, comprises 5% to 20% organic carrier and 5% to 70% silver powder. In this embodiment, the silver paste, by mass, comprises 5% to 20% organic carrier, 5% to 70% silver powder, and 5% to 15% glass powder.

[0085] II. In some embodiments, the silver paste further includes an insulating additive dispersed in an organic carrier. This insulating additive may also be referred to as a resistance modifier. Exemplarily, the insulating additive includes at least one of an organic polymer and ceramic powder. The applicant has discovered that by adding an appropriate amount of insulating additive to the silver paste, these additives can form an insulating layer between the silver powder particles, hindering electron conduction, thereby increasing the sheet resistance Rs of the heating wire 700.

[0086] For example, the insulating additive is nano-silica with a particle size of 50nm to 100nm, and the mass fraction of nano-silica in the silver paste is 2% to 5%. By adding nano-silica, a nanoscale insulating barrier can be formed between the silver powder particles, thereby increasing the sheet resistance Rs of the heating wire 700 to 100 milliohms / □ to 300 milliohms / □. At this time, a coupling agent such as KH-570 is usually added to the silver paste to improve the wettability of the silver paste, thereby facilitating the improvement of the adhesion of the silver paste to the mounting component 100.

[0087] Third, in some embodiments, the silver paste further includes a metal or compound, wherein the resistance of the metal is greater than that of the silver powder. The sheet resistance of the heating wire 700 formed before the addition of the compound is Rs1, and the sheet resistance of the heating wire 700 formed after the addition of the compound is Rs2, where Rs2 > Rs1. When these metals or compounds are mixed with the silver powder, they alter the conductivity mechanism of the silver paste, thereby increasing the overall resistance of the heating wire 700. For example, the metal may be metallic nickel or metallic cobalt, and the compound may be silver nickelate.

[0088] For example, adding 3%-6% silver nickelate by mass to silver paste can increase the sheet resistance Rs2 of the fabricated heating wire 700 to 200 milliohms / □ to 500 milliohms / □, while simultaneously improving the performance of the Ni... 2+ The charge compensation effect of silver ions improves the sintering density of the heating wire 700.

[0089] For example, by adding 5% to 8% by mass of La.Sr.CoO ceramic powder to silver paste, the sheet resistance Rs2 of the fabricated heating wire 700 can be increased to 500 milliohms / □ to 1000 milliohms / □ through the electronic conductivity characteristics of the perovskite structure.

[0090] Fourth, the applicant also discovered that the thinner the silver paste printing thickness, the thinner the conductive layer formed by the silver paste, and the longer the relative side of the electron transport path, resulting in an increase in the resistance of the heating wire 700 and a corresponding increase in the sheet resistance Rs of the heating wire 700. However, excessively thin silver paste printing thickness may lead to discontinuities in the heating wire 700 circuitry or unstable conductivity. In this application embodiment, by controlling the thickness D of the heating wire 700 to be 1μm to 20μm, it is beneficial to improve the sheet resistance Rs of the heating wire 700 on the one hand, and to ensure stable conductivity on the other. In some embodiments, the thickness D of the heating wire 700 is 10μm to 20μm. In some embodiments, the thickness D of the heating wire 700 is 4μm to 10μm.

[0091] See also Figure 2 , Figure 8 and Figure 10 , Figure 10 for Figure 8The diagram shows a cross-sectional view of the assembled structure at point BB. Figure 8 The middle section 730 of the heating line 700 is only shown in a circle around the viewing window area S1, that is, the middle section 730 includes a circle of heating line segment 701.

[0092] like Figure 8 As shown, this embodiment of the application also adopts a newly designed pattern for the heating wire 700, wherein the line width of the first segment 710 is greater than that of the middle segment 730, and the line width of the second segment 750 is greater than that of the middle segment 730, i.e., a design style that is thick at both ends and thin in the middle. For example, the line width of the first segment 710 is 1mm to 10mm, the line width of the second segment 750 is 1mm to 10mm, and the line width of the middle segment 730 is 0.5mm to 4mm. In this embodiment, the length of the heating wire 700 is 205.249mm, the line width of the first segment 710 is 4.345mm, the line width of the second segment 750 is 4.345mm, and the line width of the middle segment 730 is 1.998mm.

[0093] According to Formula 2 above, the thicker part of the heating wire 700 has lower resistance, and the thinner part has higher resistance. Given the same series current, P = I... 2 As can be seen from R, the part with higher resistance has higher power. In this embodiment of the application, the line width of the first segment 710 of the heating wire 700 is greater than that of the middle segment 730, and the line width of the second segment 750 is greater than that of the middle segment 730. This makes the power of the middle segment 730 greater than that of the first segment 710, and the power of the middle segment 730 greater than that of the second segment 750. This ensures that the power of the heating wire 700 is mainly concentrated in the middle segment 730 surrounding the viewing window area S1, allowing more power in the heating wire 700 to be concentrated around the viewing window area S1. As a result, the heat generated by the heating wire 700 is more concentrated around the viewing window area S1, and the heat is transferred to the viewing window area S1 more quickly, thereby improving the heating efficiency of the heating wire 700.

[0094] like Figure 10 As shown, the mounting component 100 is further provided with a first shielding layer 210, which is located at the edge region P1 of the mounting component 100. The heating wire 700 is located on the side of the first shielding layer 210 away from the mounting component 100. For example, the first shielding layer 210 is a black ink layer, which can also be referred to as a black edge.

[0095] It is understood that in other embodiments, the intermediate segment 730 may include multiple heating line segments 701, all of which are arranged around the viewing window area S1. The line widths of the multiple heating line segments 701 are all equal, or the multiple heating line segments 701 may include an Nth heating line segment and an (N+m)th heating line segment, which are arranged sequentially in a direction away from the viewing window area S1. The line width of the Nth heating line segment 701 is less than the line width of the (N+m)th heating line segment 701, where N ≥ 1 and N is a natural number, and m > 0 and m is a natural number. For example, when N is 1 and m is 1, the line width of the first heating line segment 701 is less than the line width of the second heating line segment 701 in the direction away from the viewing window area S1. In this embodiment, by setting the line width of the Nth heating segment 701 to be less than that of the N+mth heating segment 701 along the direction away from the viewing area S1, the line width of the heating segment 701 near the viewing area S1 is made thinner, thereby increasing the power of the heating segment 701 near the viewing area S1. This concentrates more power in the heating line 700 around the viewing area S1, ensuring that the heat generated by the heating line 700 is more concentrated around the viewing area S1, and that the heat is transferred to the viewing area S1 more quickly, further improving the heating efficiency of the heating line 700.

[0096] The heating effect of the heating wire 700 provided in the above-described embodiment of this application will be specifically explained below with reference to the effect experiment.

[0097] Example 1 and Comparative Example 1:

[0098] Example 1 provides an assembly structure including a mounting component 100 and a heating wire 700. The mounting component 100 is made of glass, and the total area of ​​the glass is 46488.5 mm². 2 The heating wire 700 is arranged in a wraparound manner on the mounting component 100. Specifically, the heating wire 700 adopts... Figure 8 The design shown has a sheet resistance of 20 milliohms / □ to 1000 milliohms / □ for the heating wire 700, and a length of less than 850 mm.

[0099] Comparative Example 1 provides an assembly structure that differs from the assembly structure of Example 1 in that the first segment 710, the middle segment 730, and the second segment 750 of the heating wire 700 in Comparative Example 1 have the same wire width, the sheet resistance of the heating wire 700 is 3 milliohms / □ to 20 milliohms / □, and the length of the heating wire 700 is 850mm to 1500mm.

[0100] Hot spot simulation experiments and defrosting simulation experiments were conducted on the assembly structures of Example 1 and Comparative Example 1, respectively. The simulation diagram of the hot spot simulation experiment of the assembly structure of Example 1 is shown in Figure 1. Figure 11 As shown, the simulation diagram of the defrosting simulation experiment of the assembly structure in Example 1 is as follows. Figure 12 As shown, the simulation diagram of the hotspot simulation experiment of the assembly structure in Comparative Example 1 is as follows. Figure 13 As shown, the simulation diagram of the defrosting simulation experiment of the assembly structure in Comparative Example 1 is as follows. Figure 14 As shown. The hot spot simulation experiment involved heating the heating wire 700 in the assembly structure under a certain voltage and power. After 30 minutes, the highest hot spot temperature on the mounting component 100 was measured. In Example 1, the voltage of the heating wire 700 was 15V and the power was 6W; in Comparative Example 1, the voltage of the heating wire 700 was 15V and the power was 6.2W. The defrosting simulation experiment involved setting the frost layer thickness on the mounting component 100 to 0.55mm. The defrosting process on the mounting component 100 was tested at -18℃ after heating the heating wire 700 for 5 minutes, 10 minutes, and 15 minutes. Figure 12 and Figure 14 The medium color fill indicates the area where the frost has melted.

[0101] Through observation Figure 11 and Figure 13 In Example 1, the highest hot spot temperature on the mounting component 100 was 80.5°C, while in Comparative Example 1, the highest hot spot temperature on the mounting component 100 was 62.2°C. This was observed... Figure 12 and Figure 14 In the assembly structure of Example 1, the mounting component 100 completes 100% defrosting in 15 minutes, while in the assembly structure of Comparative Example 1, the mounting component 100 fails to complete 100% defrosting in 15 minutes. Experimental results show that, with slightly lower power, the heating wire 700 provided in this embodiment achieves a higher peak hotspot temperature on the mounting component 100 and a higher temperature in the central viewing window area S1. Using the heating wire 700 provided in this embodiment, the heat generated by the heating wire 700 enables the mounting component 100 to complete 100% defrosting in 15 minutes, thus improving the heating efficiency of the heating wire 700.

[0102] See also Figure 2 and Figure 15 , Figure 15 for Figure 1 The diagram shows a cross-sectional view of part of the information acquisition component 1 in the first application scenario.

[0103] The information acquisition component 1 in the first application scenario also includes a first shielding layer 210 and an electrical connector 400. The first shielding layer 210 is disposed on the edge region P1 of the mounting member 100 and surrounds the viewing window region S1. In this embodiment, the first shielding layer 210 is disposed on the surface of the mounting member 100 facing the information acquisition device 500. Exemplarily, the first shielding layer 210 is a black ink layer. A heating wire 700 is disposed on the side of the first shielding layer 210 away from the mounting member 100. The heating wire 700 is made of silver paste.

[0104] The electrical connector 400 includes a power supply element 410 and a connector 430. The power supply element 410 is electrically connected between the heating wire 700 and the connector 430, and the connector 430 is used for electrical connection to a power source to heat the heating wire 700 and generate heat. Exemplarily, the power supply element 410 is made of solder or conductive adhesive. When the mass fraction of silver powder in the silver paste is ≤70%, adhesion problems may exist between the heating wire 700 and the power supply element 410, making it difficult to power the power supply element 410 with solder. In this case, the power supply element 410 of the electrical connector 400 is connected to the connector 430 with conductive adhesive to improve the adhesion between the heating wire 700 and the power supply element 410 and prevent the power supply element 410 from detaching. Exemplarily, the connector 430 can be a wire harness or an FPC (Flexible Printed Circuit).

[0105] In the first application scenario, the heating wire 700 made of silver paste does not come into contact with the adhesive layer or primer layer that connects to the peripheral accessories in the vehicle. The silver paste is not prone to sulfidation or oxidation, so there is no need to add a shielding layer to the heating wire 700.

[0106] See Figure 16 , Figure 16 for Figure 1 The diagram shows a cross-sectional view of part of the information acquisition component 1 in the second application scenario.

[0107] The difference between the information acquisition component 1 in the second application scenario and the information acquisition component 1 in the first application scenario is that the information acquisition component 1 in the second application scenario also includes a second masking layer 230.

[0108] Specifically, the second shielding layer 230 is disposed on the side of the heating wire 700 opposite to the mounting member 100 and covers the heating wire 700. For example, the second shielding layer 230 is a black ink layer or a UV (Ultraviolet) curable adhesive layer. In the second application scenario, the vehicle also includes a connector 810 and an accessory 830. The connector 810 is disposed on the side of the second shielding layer 230 opposite to the mounting member 100 and connects the second shielding layer 230 and the accessory 830. The connector 810 can be an adhesive layer used to bond the accessory 830 to the second shielding layer 230. The connector 810 can also be a base coat used to enhance the adhesion of the accessory 830 to the mounting member 100. For example, the base coat material can be a polyurethane compound. For example, the accessory 830 can be a bracket, edge strip, nail post, etc.

[0109] In the second application scenario, the heating wire 700 made of silver paste makes interference contact with the adhesive layer or base coating layer connected to the surrounding accessories 830. The surrounding accessories 830 will precipitate substances that cause the silver paste to sulfide or oxidize. By covering the heating wire 700 with a second shielding layer 230, the silver paste can be prevented from undergoing qualitative changes, thereby improving the service life and heating effect of the heating wire 700.

[0110] See Figure 17 and Figure 18 , Figure 17 This is a schematic diagram of the structure of the heating assembly 900 provided in an embodiment of this application. Figure 18 for Figure 17 The diagram shows a cross-sectional view of the heating assembly 900 in a first application scenario. Figure 17 The dashed line represents the heating line 700 in perspective.

[0111] The information acquisition component 1 in this embodiment further includes a heating component 900. The heating component 900 includes a heating wire 700, a first insulating layer 910, a second insulating layer 930, and a connector 430. The heating wire 700 is sandwiched between the first insulating layer 910 and the second insulating layer 930. The connector 430 is electrically connected to the heating wire 700 and is used to connect to a power source to heat the heating wire 700 and generate heat. In this embodiment, the first insulating layer 910 has a first clearance opening 901 that penetrates the first insulating layer 910 along its thickness direction. The second insulating layer 930 has a second clearance opening 903 that penetrates the second insulating layer 930 along its thickness direction. In the assembled heating component 900, the first clearance opening 901 and the second clearance opening 903 communicate to form a clearance window 905.

[0112] The information acquisition component 1 also includes an adhesive layer 907, which is disposed on the surface of the first shielding layer 210 facing away from the mounting member 100. In the heating component 900, the first insulating layer 910 is bonded to the adhesive layer 907, thereby connecting the first insulating layer 910 to the mounting member 100. The second insulating layer 930 is located on the side of the first insulating layer 910 facing away from the mounting member 100. The viewing area S1 of the mounting member 100 is exposed relative to the avoidance window 905.

[0113] The heating assembly 900 provided in this embodiment of the application forms a whole by sandwiching the heating wire 700 between the first insulating layer 910 and the second insulating layer 930, which avoids oxidation of the heating wire 700 due to contact with air, thus ensuring the service life and heating effect of the heating wire 700. Furthermore, by integrating the connector 430 and the heating wire 700 into a single unit to form the heating assembly 900, it can be adhered to the mounting component 100 using the adhesive layer 907 during use, thereby achieving heating, defrosting, and defogging of the mounting component 100. This is convenient to operate and, compared to setting the heating wire 700 separately, the installation efficiency of the heating assembly 900 is higher.

[0114] See Figure 19 , Figure 19 for Figure 17 The diagram shows a cross-sectional structure of the heating component 900 in a second application scenario.

[0115] In the second application scenario, the connector 810 is located on the side of the second insulating layer 930 in the heating assembly 900 that is away from the mounting member 100, and is connected between the second insulating layer 930 and the accessory 830.

[0116] Because the heating wire 700 is sandwiched between the first insulating layer 910 and the second insulating layer 930 in the heating assembly 900, the heating wire 700 is not exposed. Therefore, in the second application scenario, even if the location on the mounting part 100 where the heating assembly 900 is installed needs to interfere with the accessory 830, there is no need to set an additional shielding layer to cover the heating wire 700, saving process steps.

[0117] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
