DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the above-mentioned objects, features, and advantages of the present application clearer and easier to understand, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, and are not all of the embodiments. In the following description, many specific details are set forth to provide a complete understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so 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 an automobile pillar assembly 10, and the camera 12 collects image information outside the vehicle, thereby providing the vehicle with functions such as face recognition and driving assistance, thereby improving the intelligence level of the vehicle.

[0024] The camera 12 incorporated in the automobile pillar assembly 10 needs to acquire outside image information through the pillar trim 11, and since the camera 12 is located inside the pillar trim 11, condensation or frost on the pillar trim 11 may affect image collection by the camera 12.

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

[0026] 3, the heating region 112 is disposed around the viewing region 111. The heating unit 13 is disposed around the viewing region 111, so that the heat generated by the heating unit 13 is gradually transferred from the periphery to the intermediate viewing region 111.

[0027] When in use, the heating unit 13 located in the heating area 112 operates to generate heat, which is then transferred to the viewing area 111 to raise the temperature of the viewing area 111, thereby solving the problem of frost and condensation in the viewing area 111, so that the viewing area 111 maintains good light transmission effect and ensures that the camera 12 can always collect image information outside the pillar trim 11.

[0028] In some embodiments, the pillar trim 11 is a glass trim, and the see-through region 111 is a portion of the glass trim. The glass trim is provided with a first ink layer 14, and the first ink layer 14 does not cover the see-through region 111, so that the see-through region 111 has a see-through function. At least a portion of the first ink layer 14 is located in the heating region 112, thereby preventing components inside the heating region 112 from being seen from the outside of the vehicle. The heating unit 13 is located inside the heating region 112, and 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 region 112, and the first ink layer 14 shields the heating unit 13 from the inside.

[0029] The glass trim may be made of a variety of materials. In one or more embodiments, the glass trim may be made of the same or different materials. In exemplary embodiments, the glass trim may be made of glass (e.g., soda-lime glass, alkali aluminosilicate glass, alkali-containing borosilicate glass, and / or alkali aluminoborosilicate glass) or glass-ceramic. Examples of suitable glass-ceramics include LiO-AlO-SiO-based (i.e., LAS-based) glass-ceramics, MgO-AlO-SiO-based (i.e., MAS-based) glass-ceramics, and glass-ceramics containing a crystalline phase, where the crystalline phase is 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 may also be chemically strengthened, thermally strengthened, mechanically strengthened, or a combination thereof. In one or more embodiments, the glass trim is unstrengthened (meaning that it has not been strengthened by a chemical, thermal, or mechanical strengthening process, but may include annealed material), and in one or more specific embodiments, the glass trim has been heat-strengthened.

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

[0031] 3, the heating unit 13 includes silver paste heating wires 131, which are distributed in the heating area 112. The silver paste heating wires 131 are located inside the heating area 112. In other embodiments, the heating unit 13 may include other devices capable of generating heat, which are not specifically limited herein.

[0032] In one embodiment, as shown in FIGS. 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 on the heating area 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 area 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 area 112, and the silver paste heating wire 131 is located between the two ink layers.

[0033] In this application, the outside of a part refers to the exterior side of the vehicle, and the inside refers to the interior side of the vehicle. The first ink layer 14 mainly performs 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] 1 and 2, the automobile pillar assembly 10 further includes a bracket 16, which is connected to the pillar trim 11. A portion of the bracket 16 is adhered to the side of the second ink layer 15 away from the first ink layer 14.

[0035] When the bracket 16 and the pillar trim 11 are held in relative position by adhesion, the second ink layer 15 is interposed between the silver paste heating wire 131 and the adhesive, preventing the silver paste heating wire 131 from reacting with 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 known as polyurethane resin) or a tape such as a foam double-sided tape. The bracket 16 is adhered 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 to prevent the silver paste heating wire 131 from contacting and reacting with the PU adhesive.

[0037] As shown in FIG. 4 , in one embodiment, a first ink layer 14 is provided on the inner surface of the heating area 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 area 112, a silver paste heating wire 131 is located between these two ink layers, at least a portion of a bracket 16 is located 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] 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 being located in the heating area 112. The insulating film 132 is adhered to the heating area 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 FIG. 6, in another embodiment, the pillar trim 11 is a plastic trim, the heating unit 13 includes a heating wire and an insulating film 132 sandwiching the heating wire, the insulating film 132 is connected to the plastic trim by integral injection molding, and the insulating film 132 is located in the heating area 112.

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

[0041] 5 and 6, the insulating film 132 includes an inner layer film 1321 and an outer layer film 1322 that are stacked together, and the heating wire is located between the inner layer film 1321 and the outer layer film 1322. The outer layer film 1322 is connected to the plastic trim by adhesion or integral injection molding.

[0042] 5 and 6, a portion of the bracket 16 is located on the side of the insulating film 132 away from the plastic trim, the insulating film 132 is located inside the heating region 112, and the insulating film 132 and the 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 the present 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 FIGS. 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 FIG. 2, an enclosed space 163 is defined between the bracket 16 and the pillar trim 11, the viewing area 111 forms a part of the side wall of the enclosed space 163, and the lens of the camera 12 is located in the enclosed space 163.

[0046] A portion of the bracket 16 is tightly connected to the pillar trim 11, and a further portion of the bracket 16 protrudes in a direction away from the pillar trim 11, forming an airtight 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 see-through region 111 is a region defined by the annular region, the see-through region 111 and the portions near the inner edges of the heating region 112 both 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] 1 and 2, a ventilation hole (not shown) is further provided in the portion of the bracket 16 that defines the sealed space 163, and the automobile pillar assembly 10 further includes a waterproof breathable film 164 that covers the ventilation hole. Air can pass through the waterproof breathable film 164 to enter the sealed space 163, but moisture is blocked from leaving the sealed space 163, further preventing condensation from forming in the viewing area 111.

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

[0050] 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 energize the heating wire to operate it.

[0051] In addition, an insulating seal member 167 is further provided at the position where the first conductive terminal 165 and the second conductive terminal 166 are provided on the bracket 16, which serves as an insulating protection member and prevents a short circuit between the first conductive terminal 165 and the second conductive terminal 166.

[0052] In some embodiments, as shown in FIG. 3, the heating wire is arranged to extend and bend back and forth in the heating area 112, thereby uniformly heating each part of the heating area 112 and diffusing heat uniformly from the outer periphery of the viewing area 111 to the inside.

[0053] Since the pillar trim 11 can be directly touched from the outside of the vehicle, when the heating unit 13 generates heat, in order to avoid the temperature of the viewing area 111 being too high and causing burns, in some embodiments, the total length L of the heating wire, the wire diameter W of the heating wire, the sheet resistance R of the heating wire, and the like are further set. 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 are limited to satisfy the following relationship: 45℃≦K+M+N≦70℃ Here, K = 20.9, M = -0.0715L + 103W + 0.41D, N = 13.5U - 5.86P - 5.80Rs,

number

[0054] When the heating wire that satisfies the above formula 45℃≦K+M+N≦70℃ is activated, the maximum temperature of the pillar trim 11 is maintained at 45℃ to 70℃, thereby achieving defrosting and anti-fogging effects and avoiding the occurrence of 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 is 3 milliohms / □ to 20 milliohms / □, and the distance 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, the temperature of the fluoroscopic region and the fluoroscopic region 111 can be maintained at 45°C to 70°C by limiting each parameter of the heating wire to the above range.

[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. Each comparative example and example in the "Heating Test Data Table" below shows how 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, when the voltage and the heating wire material are constant.

[0058] [Table 1]

[0059] As can be seen from a 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 heated area 112 exceeds 70°C. As can be seen from a comparison between Comparative Example 2 and Example 1, if the distance D between any two wires after bending the heating wire back and forth is too small, heat will overlap and the temperature at the highest point of the heated area 112 will exceed 70°C. As can be seen from a comparison between Comparative Example 3 and Example 1, if the wire diameter W of the heating wire is too large, the resistance will be small, the power consumption will be too high, and the temperature at the highest point of the heated area 112 will exceed 70°C.

[0060] Regarding temperature measurement, the specific temperature rise can be measured after applying electricity for 30 minutes in a room temperature environment.

[0061] Furthermore, in some embodiments, a vehicle is provided that includes the above-described automobile pillar assembly 10. The heating unit 13 in the heating area 112 of the automobile pillar assembly 10 operates to generate heat, which is transferred to the viewing area 111 to raise the temperature of the viewing area 111, ensuring that no condensation or frost forms in the viewing area 111 even in complex environments and that the viewing area 111 has a good light transmission effect, allowing the camera 12 to capture an image of the other side of the viewing area 111 through the viewing area 111 and enabling functions dependent on the camera 12 to operate normally.

[0062] 1 and 2, the automotive pillar assembly 10 further includes a harness 17 electrically connected between the heating unit 13 and a vehicle control module, which can automatically control the operation of the heating unit 13.

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