[0034] Reference is made below to Figures 1-4 describe the front windshield assembly 100 according to an embodiment of the present utility model.
[0035] As Figure 3 shown, the front windshield assembly 100 according to an embodiment of the present utility model includes a front windshield 1 and a heating connector box body 2.
[0036] Specifically, as Figure 3 and Figure 4 shown, the surface of the heating connector box body 2 facing the front windshield 1 is a mounting surface 21. The mounting surface 21 is adhesively connected to the front windshield 1. The heating connector box body 2 is used to heat the front windshield 1. Among them, heating elements such as tungsten wires may be provided in the front windshield 1, and the heating connector box body 2 may be connected to the heating elements through a bus bar 3 to realize the heating of the front windshield 1.
[0037] In a specific embodiment, the windshield 1 is composed of multiple layers, and a heating element such as a tungsten wire can be embedded in the interlayer of the windshield 1. The heating element generates heat to heat the windshield 1 after being energized. A heating wire 4 and a connecting terminal are provided in the heating joint box body 2. The busbar 3 and the heating wire 4 are electrically connected in the heating joint box body 2 through the connecting terminal. The end of the heating wire 4 that is away from the connecting terminal extends from the heating joint box body 2 to connect to the vehicle power supply 5. The busbar 3 can be a heating joint copper foil, which is used to connect the heating element in the windshield 1 to the connecting terminal, so as to form a circuit transmission for heating the windshield 1.
[0038] The heating connector box body 2 can protect the electrical components and the connections of the electrical components therein, and prevent other components or impurities from interfering with or damaging the electrical components in the heating connector box body 2, thereby ensuring the stable operation of the circuit for heating the windshield 1, and further ensuring the stability of the heating function of the windshield 1 of the vehicle 200. By heating the windshield 1, the windshield 1 can be prevented from frosting, fogging or icing due to temperature differences, and the driving field of vision can be kept clear in cold or humid weather conditions, thereby improving driving safety and comfort.
[0039] In the prior art, a buckle is provided on the heating joint box body, and the heating joint box body is connected to the upper plate of the front enclosure for supporting the front windshield, and a mounting bracket for fixing the heating joint box body is provided on the upper plate of the front enclosure, and the heating joint box body and the mounting bracket are connected by a buckle. However, the installation space at the lower end of the front windshield is limited, and the above solution easily leads to problems such as difficulty in arranging the heating joint box body and difficulty in assembly.
[0040] In the present application, the heating joint box body 2 is bonded to the windshield 1, for example, PU glue can be applied to the mounting surface 21 of the heating joint box body 2, so that the mounting surface 21 is bonded to the inner surface of the lower end of the windshield 1 through the PU glue, so that the heating joint box body 2 and the windshield 1 can be tightly connected, and the connection stability can be ensured, thereby ensuring the stability of the heating function of the windshield 1 of the vehicle 200. At the same time, the connection structure such as the buckle can be omitted, thereby reducing the volume of the heating joint box body 2, and the space requirements for arranging and installing the heating joint box body 2 can be reduced, which can solve the problem that the installation space at the lower end of the windshield 1 is limited, resulting in the inability to arrange the heating joint box body 2 or the difficulty in installation, thereby improving the adaptability and versatility of the heating joint box body 2.
[0041] In addition, the heating joint box body 2 can be directly bonded to the front windshield 1 at the production plant, thereby reducing the assembly steps in the vehicle 200 assembly workshop. Moreover, the bonding connection operation is simple and low-cost, which can simplify the connection process between the heating joint box body 2 and the front windshield 1, and eliminate the production processes of manufacturing the above-mentioned buckles, mounting brackets and other components, thus improving the production and assembly efficiency and reducing the production and assembly costs.
[0042] For the front windshield assembly 100 according to the embodiment of the present invention, by adhesively connecting the mounting surface 21 of the heating joint box body 2 for heating the front windshield 1 to the front windshield 1, the connection stability between the heating joint box body 2 and the front windshield 1 can be ensured, thereby ensuring the stability of the function of heating the front windshield 1, preventing the front windshield 1 from frosting, fogging or icing, and further improving driving safety and comfort. At the same time, the occupied volume of the heating joint box body 2 can be reduced, and the installation and layout difficulty of the heating joint box body 2 can be lowered, thus improving the adaptability and versatility of the heating joint box body 2. In addition, the bonding connection operation is simple and low-cost, which can improve the production and assembly efficiency and reduce the production and assembly costs.
[0043] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the mounting surface 21 is provided with limiting ribs 22, and the limiting ribs 22 define a caulking space 23. By providing the limiting ribs 22, the area where the adhesive needs to be coated can be clearly indicated, the operation difficulty can be reduced, and thus the bonding efficiency can be improved. In addition, the limiting ribs 22 can confine the adhesive within the caulking space 23, preventing the adhesive from overflowing the mounting surface 21, thereby improving the connection stability between the heating joint box body 2 and the front windshield 1, and also being beneficial to improving the appearance aesthetics. An operator can coat an adhesive such as PU adhesive on the mounting surface 21 within the caulking space 23, and then press and paste the mounting surface 21 onto the inner surface at the lower end of the front windshield 1. At this time, the adhesive will fill the caulking space 23 and achieve a tight connection between the heating joint box body 2 and the front windshield 1 to ensure the connection stability.
[0044] It should be noted that the surface of the front windshield 1 close to the driving space inside the vehicle 200 is the inner surface, and the other surface opposite thereto is the outer surface.
[0045] During the specific bonding process of the heating joint box body 2 and the front windshield 1, the operator needs to first clean the bonding area of the front windshield 1 with a cleaning agent and apply a primer, then brush a primer and apply an adhesive such as PU glue on the mounting surface 21 within the caulking space 23 of the heating joint box body 2, then press the mounting surface 21 of the heating joint box body 2 towards the bonding area of the front windshield 1 and press it tightly, and finally let the bonded heating joint box body 2 and the front windshield 1 stand for several hours to cure the adhesive such as PU glue, so as to achieve the specific bonding connection between the heating joint box body 2 and the front windshield 1.
[0046] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the width of the limiting rib 22 is a, and it satisfies: 1 mm ≤ a ≤ 2 mm. If a < 1 mm, the structural strength of the limiting rib 22 cannot be guaranteed. If a > 2 mm, the width of the limiting rib 22 is too large, which will reduce the caulking space 23, resulting in a reduction in the adhesive between the heating joint box body 2 and the front windshield 1, and will also cause an increase in the weight of the heating joint box body 2, thus affecting the connection stability. Making 1 mm ≤ a ≤ 2 mm can not only ensure the structural strength of the limiting rib 22, but also ensure the size of the caulking space 23, avoid the heating joint box body 2 from being too heavy, and thus ensure the connection stability between the heating joint box body 2 and the front windshield 1.
[0047] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the height of the limiting rib 22 is d, and it satisfies: 0.2 mm ≤ d ≤ 0.5 mm. If d < 0.2 mm, the structural strength of the limiting rib 22 cannot be guaranteed, and the caulking space 23 will be reduced, resulting in a reduction in the adhesive between the heating joint box body 2 and the front windshield 1, thus affecting the connection stability. If d > 0.5 mm, the height of the limiting rib 22 is too large, which will cause the caulking space 23 to be too large, increase the amount of adhesive used, and cause an increase in cost. Making 0.2 mm ≤ d ≤ 0.5 mm can not only ensure the structural strength of the limiting rib 22, but also ensure that the size of the caulking space 23 is appropriate, thus ensuring the connection stability between the heating joint box body 2 and the front windshield 1 and controlling the cost.
[0048] In some embodiments of the present invention, as Figure 1 and Figure 2As shown, a fillet 24 is provided between the mounting surface 21 and the adjacent surface. The distance h between the limiting rib 22 and the edge of the mounting surface 21 excluding the fillet 24 satisfies: 1mm ≤ h ≤ 2mm. If h < 1mm, there is a risk that the limiting rib 22 coincides with the fillet 24, increasing the processing difficulty. If h > 2mm, the caulking space 23 will be reduced, resulting in a decrease in the adhesive between the heating joint box body 2 and the front windshield 1, thus affecting the connection stability. Making the distance between the limiting rib 22 and the edge of the mounting surface 21 excluding the fillet 24 appropriate is convenient for processing and can ensure the size of the caulking space 23, thereby ensuring the connection stability between the heating joint box body 2 and the front windshield 1.
[0049] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the limiting rib 22 includes a first rib 221 and a second rib 222. The first rib 221 extends along the length direction of the mounting surface 21 and is located at one end in the width direction of the mounting surface 21. The second rib 222 extends along the width direction of the mounting surface 21 and is located on one side of the first rib 221 in the width direction of the mounting surface 21. One end of the second rib 222 is connected to the first rib 221, and the second rib 222 is a plurality of spaced apart along the length direction of the mounting surface 21. The plurality of second ribs 222 and the first rib 221 together define the caulking space 23.
[0050] It can be understood that by setting the limiting rib 22 as the first rib 221 extending along the length direction of the mounting surface 21 and a plurality of second ribs 222 extending along the width direction of the mounting surface 21, it is convenient to define multiple caulking spaces 23 and ensure the size of the caulking space 23, thereby ensuring the connection stability between the heating joint box body 2 and the front windshield 1. At the same time, the extending direction of the limiting rib 22 is regular and the structure is simple, which is convenient for processing and can reduce the production cost.
[0051] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the length of the first rib 221 is c, and satisfies: 43mm ≤ c ≤ 45mm. If c < 43mm, the length of the first rib 221 is too short, which will reduce the caulking space 23, resulting in a decrease in the bonding area between the heating joint box body 2 and the front windshield 1, thus affecting the connection stability. If c > 45mm, the length of the first rib 221 is too long, and there is even a risk of exceeding the mounting surface 21, which will cause an increase in the weight of the heating joint box body 2 and increase the cost. Making 43mm ≤ c ≤ 45mm can not only ensure the size of the bonding area between the heating joint box body 2 and the front windshield 1, thereby ensuring the connection stability, but also ensure that the first rib 221 is within the mounting surface 21 and control the cost.
[0052] In some embodiments of the present utility model, such as Figure 1 and Figure 2 shown, the length of the second rib 222 is b, and it satisfies: 14 mm ≤ b ≤ 16 mm. If b < 14 mm, the length of the second rib 222 is too short, which will reduce the caulking space 23, resulting in a reduction in the bonding area between the heating joint box body 2 and the front windshield 1, thereby affecting the connection stability; if b > 16 mm, the length of the second rib 222 is too long, and there is even a risk of exceeding the mounting surface 21, which will cause an increase in the weight of the heating joint box body 2 and increase the cost. Making 14 mm ≤ b ≤ 16 mm can not only ensure the size of the bonding area between the heating joint box body 2 and the front windshield 1, thereby ensuring the connection stability, but also ensure that the second rib 222 is within the mounting surface 21 and control the cost.
[0053] The vehicle 200 according to an embodiment of the present utility model includes: the above-mentioned front windshield assembly 100.
[0054] The vehicle 200 according to an embodiment of the present utility model can ensure the connection stability between the heating joint box body 2 and the front windshield 1 by adhesively connecting the mounting surface 21 of the heating joint box body 2 for heating the front windshield 1 to the front windshield 1, thereby ensuring the stability of the function of heating the front windshield 1, preventing the front windshield 1 from frosting, fogging or icing, and further improving driving safety and comfort. At the same time, it can also reduce the occupied volume of the heating joint box body 2, reduce the installation and layout difficulty of the heating joint box body 2, and thus improve the adaptability and versatility of the heating joint box body 2. In addition, the adhesive connection operation is simple and the cost is low, which can improve the production and assembly efficiency and reduce the production and assembly cost.
[0055] In some embodiments of the present utility model, there are a plurality of heating joint box bodies 2 spaced apart in the left-right direction of the vehicle 200. The plurality of heating joint box bodies 2 can heat the front windshield 1 simultaneously in the left-right direction of the vehicle 200, which can enhance the heating effect of the front windshield 1, improve the temperature uniformity of the front windshield 1, and prevent problems such as frosting, fogging or icing in some areas of the front windshield 1, thereby further improving driving safety and comfort.
[0056] It should be noted that the left-right direction of the vehicle 200 is the width direction of the vehicle 200.
[0057] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.
