MODE FOR CARRYING OUT THE INVENTION

[0022] In order to make the above objects, features, and advantages of the present application clearer and easier to understand, the following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings. As is clear, the described embodiments are only some of the embodiments of the present application, not all. In the following description, many specific details are described in order to provide a complete understanding of the present application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0023] In the field of vehicles, as shown in FIGS. 1 to 3, a camera 12 is incorporated in a pillar assembly 10 for an automobile. By collecting vehicle exterior image information with the camera 12, functions such as a face recognition function and a driving assistance function can be imparted to the vehicle, and the intelligent level of the vehicle can be improved.

[0024] The camera 12, which is incorporated into the automotive pillar assembly 10, needs to acquire external image information through the pillar trim 11. Since the camera 12 is located inside the pillar trim 11, condensation or frost on the pillar trim 11 may affect image acquisition by the camera 12.

[0025] Based on this, the present application provides, in several embodiments as shown in Figures 1 to 3, an automotive pillar assembly 10 including a pillar trim 11, a camera 12, and a heating unit 13. The pillar trim 11 has a light-transmitting viewing area 111 and a heating area 112. The camera 12 is positioned corresponding to the viewing area 111 and can capture an image of the viewing area 111 located on the side of the viewing area 111 away from the camera 12, through the viewing area 111. The heating unit 13 is located in the heating area 112 and the heat generated by the heating unit 13 can be transferred from the heating area 112 to the viewing area 111.

[0026] In one embodiment, as shown in Figure 3, the heating region 112 is provided around the transparent region 111. By providing the heating unit 13 around the transparent region 111, the heat generated by the heating unit 13 is gradually transferred from the surrounding area to the intermediate transparent region 111.

[0027] During use, the heating unit 13 located in the heating region 112 operates to generate heat, which is then transferred to the transparent region 111, raising its temperature. This solves the problem of frost and condensation forming in the transparent region 111. Therefore, the transparent region 111 maintains a good light transmission effect, ensuring that the camera 12 can always collect image information from outside the pillar trim 11.

[0028] In some embodiments, the pillar trim 11 is a glass trim, and the transparent area 111 is a portion of the glass trim. The glass trim is provided with a first ink layer 14, and since the first ink layer 14 does not cover the transparent area 111, the transparent area 111 has a transparent function. At least a portion of the first ink layer 14 is located in the heating area 112, thereby preventing the parts inside the heating area 112 from being seen from the outside of the vehicle. The heating unit 13 is located inside the heating area 112, the first ink layer 14 is provided on the inner surface of the glass trim, the heating unit 13 is provided in the first ink layer 14 of the heating area 112, and the first ink layer 14 shields the heating unit 13 inward.

[0029] The materials used for the glass trim vary. In one or more embodiments, the materials used for the glass trim may be the same or different. In exemplary embodiments, the glass trim may be glass (e.g., soda-lime glass, alkali aluminosilicate glass, alkali borosilicate glass and / or alkali aluminoborsilicate glass) or glass ceramic. Examples of suitable glass ceramics include Li2O-Al2O3-SiO2 (i.e., LAS) glass ceramics, MgO-Al2O3-SiO2 (i.e., MAS) glass ceramics, and glass ceramics containing a crystalline phase, the crystalline phase being one or more crystalline phases selected from mullite, spinel, α-quartz, β-quartz solid solution, petalite, lithium disilicate, β-spodumene, nepheline, and alumina. The glass trim can also be subjected to chemical strengthening, thermal strengthening, mechanical strengthening, or a combination thereof. In one or more embodiments, the glass trim is unstrengthened (meaning it is not strengthened by a chemical, thermal, or mechanical strengthening process, but may contain annealed material), and in one or more specific embodiments, the glass trim is thermally strengthened.

[0030] In another embodiment, the pillar trim 11 is a plastic trim, and the transparent region 111 of the plastic trim can transmit light rays and has a transparent function, so that the camera 12 can collect image information of the outside of the plastic trim through this region. The heating region 112 of the plastic trim may be a light-impermeable structure, and can shield components placed inside the heating region 112.

[0031] In one embodiment, as shown in Figure 3, the heating unit 13 includes a silver paste heating wire 131, which is distributed in a heating region 112. The silver paste heating wire 131 is located inside the heating region 112. In another embodiment, the heating unit 13 may include other devices capable of generating heat, and are not specifically limited herein.

[0032] In one embodiment, as shown in Figures 2 to 6, the heating unit 13 includes a silver paste heating wire 131, the pillar trim 11 is a glass trim, a first ink layer 14 and a second ink layer 15 are sequentially laminated in the heating region 112 of the glass trim, and the silver paste heating wire 131 is located between the first ink layer 14 and the second ink layer 15. The silver paste heating wire 131 is fixed to the heating region 112 of the glass trim by the two ink layers. The first ink layer 14 is sintered on the inner surface of the glass trim, and the second ink layer 15 is printed on the side of the first ink layer 14 away from the heating region 112, and the silver paste heating wire 131 is located between the two ink layers.

[0033] In this application, the outside of a component refers to the side facing the external space of the vehicle, and the inside refers to the side facing the internal space of the vehicle. The first ink layer 14 mainly serves a shielding function, and the second ink layer 15 protects the silver paste heating wire 131 and prevents dust and water vapor from adhering to the silver paste heating wire 131 due to its exposure to the outside.

[0034] Furthermore, as shown in Figures 1 and 2, the automotive pillar assembly 10 further includes a bracket 16, which is connected to the pillar trim 11. A portion of the bracket 16 is bonded to the side of the second ink layer 15 that is away from the first ink layer 14.

[0035] When the bracket 16 and the pillar trim 11 maintain their relative positions through adhesion, the second ink layer 15 is interposed between the silver paste heating wire 131 and the adhesive, preventing a reaction between the silver paste heating wire 131 and the adhesive.

[0036] For example, in one embodiment, an adhesive unit 161 is provided between the second ink layer 15 and the bracket 16. The adhesive unit 161 may be a PU adhesive (also called polyurethane resin) or a tape such as foamed double-sided tape. The bracket 16 is bonded to the side of the second ink layer 15 away from the glass trim by the PU adhesive, and the second ink layer 15 isolates the silver paste heating wire 131 from the PU adhesive, preventing the silver paste heating wire 131 from coming into contact with and reacting with the PU adhesive.

[0037] As shown in Figure 4, in one embodiment, a first ink layer 14 is provided on the inner surface of the heating region 112 of the glass trim, a second ink layer 15 is printed on the side of the first ink layer 14 away from the heating region 112, a silver paste heating wire 131 is located between these two ink layers, a bracket 16 is located at least partially on the side of the second ink layer 15 away from the first ink layer 14, and an adhesive unit 161 is provided between the bracket 16 and the second ink layer 15.

[0038] As shown in Figure 5, in another embodiment, the pillar trim 11 is a plastic trim, and the heating unit 13 includes a heating wire and an insulating film 132 sandwiching the heating wire, the insulating film 132 located in the heating region 112. The insulating film 132 is bonded to the heating region 112 of the pillar trim 11. An adhesive 162 is provided between the insulating film 132 and the pillar trim 11.

[0039] Alternatively, as shown in Figure 6, in another embodiment, the pillar trim 11 is a plastic trim, and the heating unit 13 includes a heating wire and an insulating film 132 sandwiching the heating wire, the insulating film 132 being integrally injection-molded to the plastic trim, and the insulating film 132 being located in the heating region 112.

[0040] In other words, if the pillar trim 11 is a plastic trim, the insulating film 132 and the plastic trim can be integrally connected by bonding or integral injection molding, and furthermore, the heating wire can be reliably positioned in the heating region 112 of the plastic trim.

[0041] As shown in Figures 5 and 6, the insulating film 132 includes a laminated inner film 1321 and an outer film 1322, with the heating wire positioned between the inner film 1321 and the outer film 1322. The outer film 1322 is attached to the plastic trim by bonding or integral injection molding.

[0042] Furthermore, as shown in Figures 5 and 6, a portion of the bracket 16 is located away from the plastic trim of the insulating film 132, the insulating film 132 is located inside the heating region 112, and the insulating film 132 and heating wire are fixed between the bracket 16 and the plastic trim. The inner layer film 1321 is located between the outer layer film 1322 and the bracket 16.

[0043] In this application, the heating wire may be a silver paste heating wire 131. In some embodiments, the silver paste heating wire 131 is sandwiched within an insulating film 132.

[0044] Furthermore, in some embodiments, as shown in Figures 1 and 2, the pillar trim 11 is located outside the bracket 16, and the heating unit 13 is located between the pillar trim 11 and the bracket 16.

[0045] As shown in Figure 2, a sealed space 163 is defined between the bracket 16 and the pillar trim 11, the transparent area 111 constitutes a part of the side wall of the sealed space 163, and the lens of the camera 12 is located in the sealed space 163.

[0046] The bracket 16 is partially connected in close contact with the pillar trim 11, and a portion of it protrudes away from the pillar trim 11, forming a sealed space 163 between the bracket 16 and the pillar trim 11.

[0047] In some embodiments, a portion of the heating region 112 also constitutes a portion of the side wall of the sealed space 163. Assuming that the heating region 112 is an annular region and the transparent region 111 is the region defined by the annular region, the portions near the inner edges of both the transparent region 111 and the heating region 112 constitute a portion of the side wall of the sealed space 163, and the outer edge portion of the heating region 112 is tightly connected to the bracket 16.

[0048] Furthermore, as shown in Figures 1 and 2, ventilation holes (not shown) are further provided in the portion of the bracket 16 that defines the sealed space 163, and the automotive pillar assembly 10 further includes a waterproof and breathable film 164 that shields the ventilation holes. Air can pass through the waterproof and breathable film 164 into the sealed space 163, while moisture is blocked from entering the sealed space 163, further preventing condensation in the transparent area 111.

[0049] Furthermore, when heat is generated by the heating unit 13, the gas in the surrounding space increases in temperature and expands in volume, allowing the waterproof and breathable film 164 to maintain the air pressure balance between the inside and outside, and further ensuring the reliability of the tight connection between the pillar trim 11 and the bracket 16.

[0050] In one embodiment, as shown in Figures 1 and 2, the heating unit 13 includes a heating wire. The bracket 16 is further provided with a first conductive terminal 165 and a second conductive terminal 166, which are electrically connected to both ends of the heating wire, respectively. The first conductive terminal 165 and the second conductive terminal 166 are used to connect to an external circuit and operate by supplying current to the heating wire.

[0051] Furthermore, an insulating sealing member 167 is provided at the position where the first conductive terminal 165 and the second conductive terminal 166 are located on the bracket 16, to serve as insulating protection and prevent short circuits between the first conductive terminal 165 and the second conductive terminal 166.

[0052] In some embodiments, as shown in Figure 3, the heating wire is arranged to extend in a reciprocating bend within the heating region 112, thereby ensuring that each part of the heating region 112 is heated uniformly and that heat diffuses uniformly from the outer periphery to the inner side of the transparent region 111.

[0053] Since the pillar trim 11 can be directly touched from outside the vehicle, in order to avoid causing burns due to the temperature of the transparent area 111 becoming too high when heat is generated by the heating unit 13, in some embodiments, the total length L of the heating wire, the wire diameter W of the heating wire, and the sheet resistance R of the heating wire are further specified. S , the distance D between any two adjacent wires formed after the heating wire is bent, the voltage U applied to the heating wire, and the power consumption P of the heating wire. Between the numbers It is limited to satisfy the following relationship: 45 ≤ K + M + N ≤ 70 Here, K=20.9, M=-0.0715L+103W+0.41D, and N=13.5U-5.86P-5.80Rs.

number

[0054] The above formula 45≦ K+M+N≦ 70 When the filling heating wire is activated, the maximum temperature of the pillar trim 11 is maintained at 45°C to 70°C, achieving defrosting and anti-fogging effects while preventing burn accidents.

[0055] The total length L of the heating wire is 850 mm to 1500 mm, the wire diameter W of the heating wire is 0.4 mm to 1.0 mm, and the sheet resistance R of the heating wire is S The resistance is 3 milliohms / □ to 20 milliohms / □, and the spacing D between any two adjacent wires formed after the heating wire is bent is 4 mm to 10 mm.

[0056] When the input voltage U of the heating wire is 10V to 24V, by limiting each parameter of the heating wire to the above range, heating area 112 The temperature can be maintained between 45°C and 70°C.

[0057] For example, in one embodiment, the heating wire is a silver paste heating wire 131, the total length L of the heating wire is 1013 mm, the wire diameter W of the heating wire is 0.5 mm, and the distance D between any two adjacent wires formed after the heating wire is bent is 4 mm. The comparative examples and embodiments in the "Heating Test Data Table" below show the temperature changes when parameters such as the total length L of the heating wire, the wire diameter W of the heating wire, and the distance D between two adjacent wires are changed, while the voltage and the material of the heating wire are constant.

[0058] [Table 1]

[0059] As can be seen from the comparison between Comparative Example 1 and Example 1 in the table above, if the total length L of the heating wire is too small, the power consumption is too high and the temperature at the highest point of the heating region 112 exceeds 70°C. As can be seen from the comparison between Comparative Example 2 and Example 1, if the distance D between any two wires after the heating wire has been bent back and forth is too small, the heat is superimposed and the temperature at the highest point of the heating region 112 exceeds 70°C. As can be seen from the comparison between Comparative Example 3 and Example 1, if the wire diameter W of the heating wire is too large, the resistance is too low, the power consumption is too high and the temperature at the highest point of the heating region 112 exceeds 70°C.

[0060] For temperature measurement, the specific temperature rise can be measured after applying power for 30 minutes in a normal temperature environment.

[0061] Furthermore, in several embodiments, a vehicle including the above-described automotive pillar assembly 10 is provided. The heating unit 13 of the heating region 112 of the automotive pillar assembly 10 operates to generate heat, and this heat is transferred to the transparent region 111 to raise the temperature of the transparent region 111. In addition, condensation and frost do not occur in the transparent region 111 even in complex environments, and the transparent region 111 is guaranteed to have a good light transmission effect. As a result, the camera 12 can capture an image of the other side of the transparent region 111 through the transparent region 111, and functions that depend on the camera 12 can operate normally.

[0062] In some embodiments, as shown in Figures 1 and 2, the automotive pillar assembly 10 further includes a harness 17, which is electrically connected between the heating unit 13 and the vehicle control module. The vehicle control module can automatically control the operation of the heating unit 13.

[0063] In one embodiment, both the first conductive terminal 165 and the second conductive terminal 166 are connected to one end of the harness 17, and the other end of the harness 17 is electrically connected to a vehicle control module.
