Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a galvanized steel plate structural member and a vehicle. Background Art

[0002] In the field of automobile manufacturing, laser welding technology has become an important joining process. Especially in the manufacturing process of the outer panel of the automobile trunk lid, the application of this technology is becoming increasingly widespread. The trend of the continuous elongation and high brightness of automobile tail lights has further promoted the application demand of laser welding technology.

[0003] Laser welding has extremely high requirements for the precise control of the welding gap. Whether the gap is too large or too small, it will seriously affect the welding quality and may even lead to welding failure. In addition, the vehicle body structure uses steel plates. To reduce or prevent the possibility of steel plate rusting, a zinc layer is usually plated on the surface of the steel plate, thereby improving the corrosion resistance. When different components are joined by laser welding, high temperature will cause the galvanized layer to evaporate to form zinc vapor, resulting in the appearance of bubbles or false welding in the weld seam, affecting the stability of the welded connection of the steel plates. Therefore, it needs to be solved. Summary of the Utility Model

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] Reference will be made below to Figures 1-7 describe the galvanized steel sheet structural member 100 according to an embodiment of the first aspect of the present invention.

[0035] Referring to Figure 1 , Figure 2 and Figure 4 , the galvanized steel sheet structural member 100 according to an embodiment of the first aspect of the present invention includes a first component 1 and a second component 2. The first component 1 has a first connecting flange 11, and the second component 2 has a second connecting flange 21. The second connecting flange 21 is stacked with the first connecting flange 11 and the second connecting flange 21 is welded to the first connecting flange 11. The first connecting flange 11 can enhance the overall structural strength of the first component 1, and the second connecting flange 21 can enhance the overall structural strength of the second component 2. The second connecting flange 21 is stacked with the first connecting flange 11, which can make the overall structure of the first component 1 and the second component 2 compact, and the second connecting flange 21 is welded to the first connecting flange 11, which can make the connection between the first component 1 and the second component 2 simple and have strong stability.

[0036] By overlapping the first connecting flange 11 and the second connecting flange 21 and welding the second connecting flange 21 to the first connecting flange 11, the contact area between the first component 1 and the second component 2 can be increased, and thus the stability of the welded connection between the first component 1 and the second component 2 can be enhanced.

[0037] Wherein, a first convex structure 41 is formed on at least one of the first connecting flange 11 and the second connecting flange 21, and the first convex structure 41 is located between the first connecting flange 11 and the second connecting flange 21. The first convex structure 41 can enhance the structural strength of the first connecting flange 11 or the second connecting flange 21. By the first convex structure 41 being located between the first connecting flange 11 and the second connecting flange 21, there can also be a certain gap between the first connecting flange 11 and the second connecting flange 21. When the first connecting flange 11 and the second connecting flange 21 are welded, this part of the gap can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 due to high temperature, and thus the possibility of generating bubbles on the first component 1 or the second component 2 or occurring false soldering between the first connecting flange 11 and the second connecting flange 21 can be reduced or avoided, which is beneficial to improving the stability of the welded connection between the first component 1 and the second component 2.

[0038] For the galvanized steel structural member 100 according to an embodiment of the present invention, since a first convex structure 41 is formed on at least one of the first connecting flange 11 and the second connecting flange 21, and the first convex structure 41 is located between the first connecting flange 11 and the second connecting flange 21, when the first component 1 and the second component 2 are welded, the first convex structure 41 can make there be a certain gap between the first connecting flange 11 and the second connecting flange 21, and this part of the gap can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 due to high temperature, and thus the stability of the welded connection between the first component 1 and the second component 2 can be improved.

[0039] Refer to Figure 1 、 Figure 6 and Figure 7 According to some embodiments of the present invention, both the first connecting flange 11 and the second connecting flange 21 extend along a first direction (for example, along Figure 1extends in the e1 direction in it. The first convex structure 41 includes a plurality of first bosses 411 arranged at intervals along the first direction. The plurality of first bosses 411 arranged at intervals along the first direction can further improve the structural strength of the first connecting flange 11 or the second connecting flange 21, and the plurality of first bosses 411 can make there be a certain gap at multiple positions along the first direction between the first connecting flange 11 and the second connecting flange 21. When the first connecting flange 11 and the second connecting flange 21 are welded, these gaps can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 due to high temperature, and further reduce or avoid the possibility of bubbles generating on the first component 1 or the second component 2 or false soldering occurring between the first connecting flange 11 and the second connecting flange 21, thereby improving the welding quality between the first component 1 and the second component 2 and being beneficial to improving the stability of the welded connection between the first component 1 and the second component 2.

[0040] For example, the second connecting flange 21 is formed with the first convex structure 41. When the first component 1 and the second component 2 are welded, by welding and connecting with the first connecting flange 11 through a plurality of first bosses 411 arranged at intervals along the first direction, the stability of the connection between the first connecting flange 11 and the second connecting flange 21 can be enhanced, thereby being beneficial to enhancing the overall structural strength of the first component 1 and the second component 2; and, the plurality of first bosses 411 arranged at intervals along the first direction can make there be a certain gap at multiple positions along the first direction between the first connecting flange 11 and the second connecting flange 21. These gaps can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 during the welding process, and further reduce or avoid the possibility of bubbles generating on the first component 1 or the second component 2 or false soldering occurring between the first connecting flange 11 and the second connecting flange 21, thereby improving the stability of the welded connection between the first component 1 and the second component 2.

[0041] In the description of the present utility model, the meaning of "a plurality of" is two or more.

[0042] Refer to Figures 5-7, according to some embodiments of the present utility model, the thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21 is 0.1 mm to 0.3 mm. For example, the thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21 may be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, etc. By ensuring that the thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21 is not less than 0.1 mm, it can ensure that the gap between the first connecting flange 11 and the second connecting flange 21 allows the zinc vapor generated during the welding process to escape smoothly, reducing or avoiding the possibility of bubbles forming on the first component 1 or the second component 2 or poor welding occurring between the first connecting flange 11 and the second connecting flange 21; by ensuring that the thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21 is not greater than 0.3 mm, while enhancing the welding connection stability between the first connecting flange 11 and the second connecting flange 21, it can avoid the gap between the first connecting flange 11 and the second connecting flange 21 from being too large due to the excessive thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21. An overly large gap between the first connecting flange 11 and the second connecting flange 21 will reduce the welding connection stability between the first connecting flange 11 and the second connecting flange 21.

[0043] By the thickness dimension w1 of the first boss 411 in the stacking direction of the first connecting flange 11 and the second connecting flange 21 being 0.1 mm to 0.3 mm, it can ensure that the gap between the first connecting flange 11 and the second connecting flange 21 allows the zinc vapor generated during the welding process to escape smoothly, and can enhance the welding connection stability between the first connecting flange 11 and the second connecting flange 21.

[0044] Refer to Figure 6 and Figure 7, according to some embodiments of the present utility model, the extension length w2 of the first boss 411 in the first direction is 15 mm to 25 mm. For example, the extension length w2 of the first boss 411 in the first direction can be 15 mm, 18 mm, 21 mm, 23 mm, 25 mm, etc. By ensuring that the extension length w2 of the first boss 411 in the first direction is not less than 15 mm, when the first connecting flange 11 and the second connecting flange 21 are welded, the contact area between the first boss 411 and the first connecting flange 11 or the second connecting flange 21 can be ensured to be sufficient, thereby ensuring strong stability of the welded connection between the first connecting flange 11 and the second connecting flange 21; by ensuring that the extension length w2 of the first boss 411 in the first direction is not greater than 25 mm, it can be avoided that the gap between the first connecting flange 11 and the second connecting flange 21 is too large due to the excessive extension length w2 of the first boss 411 in the first direction, and too large a gap between the first connecting flange 11 and the second connecting flange 21 will reduce the connection stability between the first connecting flange 11 and the second connecting flange 21.

[0045] By ensuring that the extension length w2 of the first boss 411 in the first direction is 15 mm to 25 mm, when the first connecting flange 11 and the second connecting flange 21 are welded, the contact area between the first boss 411 and the first connecting flange 11 or the second connecting flange 21 can be ensured to be sufficient, thereby ensuring strong stability of the welded connection between the first connecting flange 11 and the second connecting flange 21.

[0046] Refer to Figure 6 and Figure 7 , according to some embodiments of the present utility model, the first boss 411 extends along the first direction, and the width w3 of the first boss 411 is 6 mm to 10 mm. For example, the first boss 411 extends along the first direction, and the width w3 of the first boss 411 can be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc. By ensuring that the width w3 of the first boss 411 is not less than 6 mm, when the first connecting flange 11 and the second connecting flange 21 are welded, the contact area between the first boss 411 and the first connecting flange 11 or the second connecting flange 21 can be ensured to be sufficient, thereby ensuring strong stability of the welded connection between the first connecting flange 11 and the second connecting flange 21; by ensuring that the width w3 of the first boss 411 is not greater than 10 mm, it can be avoided that the gap between the first connecting flange 11 and the second connecting flange 21 is too large due to the excessive extension length w2 of the first boss 411 in the first direction, and too large a gap between the first connecting flange 11 and the second connecting flange 21 will reduce the connection stability between the first connecting flange 11 and the second connecting flange 21.

[0047] The width w3 of the first boss 411 is 6 mm to 10 mm. When the first connecting flange 11 and the second connecting flange 21 are welded, it can ensure that the contact area between the first boss 411 and the first connecting flange 11 or the second connecting flange 21 is sufficient, thereby ensuring strong stability of the welded connection between the first connecting flange 11 and the second connecting flange 21.

[0048] Referring to Figure 6 and Figure 7 According to some embodiments of the present invention, the extension length w2 of the first boss 411 in the first direction is 15 mm to 25 mm; and, the first boss 411 extends along the first direction, and the width w3 of the first boss 411 is 6 mm to 10 mm. When the first connecting flange 11 and the second connecting flange 21 are welded, it can ensure that the contact area between the first boss 411 and the first connecting flange 11 or the second connecting flange 21 is sufficient, thereby ensuring strong stability of the welded connection between the first connecting flange 11 and the second connecting flange 21.

[0049] Referring to Figure 2 and Figure 4 According to some embodiments of the present invention, a plurality of first bosses 411 are formed on the first connecting flange 11 and arranged at intervals in the first direction. The distance between adjacent first bosses 411 on the first connecting flange 11 in the first direction is greater than the length of the first boss 411 in the first direction, which can make the first connecting flange 11 and the second connecting flange 21 between adjacent bosses fit well, reduce the possibility of dust and other impurities flowing into the inside of the galvanized steel structure member 100 through the gap between the first connecting flange 11 and the second connecting flange 21 between adjacent first bosses 411, and the first connecting flange 11 and the second connecting flange 21 between adjacent bosses fit tightly, which can make the overall structure of the first connecting flange 11 and the second connecting flange 21 after welding have strong strength.

[0050] Referring to Figure 2 and Figure 4 According to some embodiments of the present invention, a plurality of first bosses 411 are formed on the second connecting flange 21 and arranged at intervals in the first direction. The distance between adjacent first bosses 411 on the second connecting flange 21 in the first direction is greater than the length of the first boss 411 in the first direction, which can make the first connecting flange 11 and the second connecting flange 21 between adjacent bosses fit well, reduce the possibility of dust and other impurities flowing into the inside of the galvanized steel structure member 100 through the gap between the first connecting flange 11 and the second connecting flange 21 between adjacent first bosses 411, and the first connecting flange 11 and the second connecting flange 21 between adjacent bosses fit tightly, which can make the overall structure of the first connecting flange 11 and the second connecting flange 21 after welding have strong strength.

[0051] Reference Figure 2 and Figure 4 According to some embodiments of the present utility model, a plurality of first bosses 411 are formed on the first connecting flange 11 at intervals in the first direction, and the distance between adjacent first bosses 411 on the first connecting flange 11 in the first direction is greater than the length of the first boss 411 in the first direction; and, a plurality of first bosses 411 are formed on the second connecting flange 21 at intervals in the first direction, and the distance between adjacent first bosses 411 on the second connecting flange 21 in the first direction is greater than the length of the first boss 411 in the first direction. This can make the first connecting flange 11 and the second connecting flange 21 between adjacent bosses fit well, reduce the possibility of dust or moisture flowing into the interior of the galvanized steel structure member 100 through the gap between the first connecting flange 11 and the second connecting flange 21 between adjacent first bosses 411, and the first connecting flange 11 and the second connecting flange 21 between adjacent bosses are closely attached, which can make the overall structure of the first connecting flange 11 and the second connecting flange 21 after welding have strong structural strength.

[0052] Reference Figure 1 and Figure 3 According to some embodiments of the present utility model, the galvanized steel structure member 100 is the outer panel of the trunk lid of a vehicle. A first raised structure 41 is formed on at least one of the first connecting flange 11 of the first component 1 and the second connecting flange 21 of the second component 2, and the first raised structure 41 is located between the first connecting flange 11 and the second connecting flange 21. When the first component 1 and the second component 2 are welded, the first raised structure 41 can make a certain gap exist between the first connecting flange 11 and the second connecting flange 21. This part of the gap can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 due to high temperature, and further improve the welding connection stability between the first component 1 and the second component 2, thereby improving the overall structural strength of the outer panel of the trunk lid of the vehicle.

[0053] Reference Figure 1 、 Figure 2 and Figure 4 According to some embodiments of the present utility model, the galvanized steel structure member 100 further includes a third component 3. The second component 2 is connected between the first component 1 and the third component 3. The first component 1 is the upper outer panel of the trunk lid, the second component 2 is the taillight box, and the third component 3 is the lower outer panel of the trunk lid. Among them, the second component 2 further has a third connecting flange 22, the third component 3 has a fourth connecting flange 31, the fourth connecting flange 31 and the third connecting flange 22 are stacked and the fourth connecting flange 31 and the third connecting flange 22 are welded together. A second raised structure 42 is formed on at least one of the fourth connecting flange 31 and the third connecting flange 22, and the second raised structure 42 is located between the fourth connecting flange 31 and the third connecting flange 22.

[0054] The third connecting flange 22 can enhance the overall structural strength of the second component 2, and the fourth connecting flange 31 can enhance the overall structural strength of the third component 3. The fourth connecting flange 31 and the third connecting flange 22 are overlapped, which can make the overall structure of the second component 2 and the third component 3 compact. Moreover, the fourth connecting flange 31 and the third connecting flange 22 are welded together, which can make the connection mode between the second component 2 and the third component 3 simple and have strong stability. By overlapping the fourth connecting flange 31 and the third connecting flange 22 and welding the fourth connecting flange 31 and the third connecting flange 22 together, the contact area between the third component 3 and the second component 2 can be increased, and further the stability of the welded connection between the third component 3 and the second component 2 can be enhanced.

[0055] The second convex structure 42 can enhance the structural strength of the third connecting flange 22 or the fourth connecting flange 31. By the second convex structure 42 being located between the fourth connecting flange 31 and the third connecting flange 22, there can be a certain gap between the fourth connecting flange 31 and the third connecting flange 22. When the fourth connecting flange 31 and the third connecting flange 22 are welded, this part of the gap can facilitate the escape of zinc vapor generated by the fourth connecting flange 31 and the third connecting flange 22 due to high temperature. Furthermore, the possibility of generating bubbles on the third component 3 or the second component 2 or of occurring a false weld between the fourth connecting flange 31 and the third connecting flange 22 can be reduced or avoided, which is beneficial to improving the stability of the welded connection between the third component 3 and the second component 2, and thus the overall structural strength after welding the taillight box and the outer panel of the luggage compartment lid can be improved.

[0056] Refer to Figure 2 , according to some embodiments of the present utility model, both the third connecting flange 22 and the fourth connecting flange 31 extend along the first direction, and the second convex structure 42 includes a plurality of second convex platforms 421 arranged at intervals along the first direction. The plurality of second convex platforms 421 arranged at intervals along the first direction can further improve the structural strength of the third connecting flange 22 or the fourth connecting flange 31, and the plurality of second convex platforms 421 can make there be a certain gap at multiple positions along the first direction between the third connecting flange 22 and the fourth connecting flange 31. When the third connecting flange 22 and the fourth connecting flange 31 are welded, these gaps can facilitate the escape of zinc vapor generated by the third connecting flange 22 or the fourth connecting flange 31 due to high temperature, thereby improving the stability of the welded connection between the first component 1 and the second component 2.

[0057] Optionally, the thickness dimension of the second boss 421 in the stacking direction of the third connecting flange 22 and the fourth connecting flange 31 is 0.1 mm to 0.3 mm, which can ensure that the gap between the third connecting flange 22 and the fourth connecting flange 31 allows the zinc vapor generated during the welding process to escape smoothly, and can enhance the welding connection stability between the third connecting flange 22 and the fourth connecting flange 31.

[0058] Optionally, the extension length of the second boss 421 in the first direction is 15 mm to 25 mm. When the third connecting flange 22 and the fourth connecting flange 31 are welded, it can ensure that the contact area between the second boss 421 and the third connecting flange 22 or the fourth connecting flange 31 is sufficient, thereby ensuring strong stability of the welding connection between the third connecting flange 22 and the fourth connecting flange 31.

[0059] Optionally, the second boss 421 extends along the first direction, and the width w3 of the second boss 421 is 6 mm to 10 mm. When the first connecting flange 11 and the second connecting flange 21 are welded, it can ensure that the contact area between the first boss 411 and the third connecting flange 22 or the fourth connecting flange 31 is sufficient, thereby ensuring strong stability of the welding connection between the third connecting flange 22 and the fourth connecting flange 31.

[0060] Referring to Figure 2 , according to some embodiments of the present invention, the first protruding structure 41 and the second protruding structure 42 are both formed on the second component 2. Since the first component 1 is the outer panel of the trunk lid, the second component 2 is the taillight box, and the third component 3 is the inner panel of the trunk lid, compared with the first component 1 and the third component 3, the structure of the second component 2 is simpler. By forming the first protruding structure 41 and the second protruding structure 42 on the second component 2, the overall structure of the first protruding structure 41, the second protruding structure 42, and the second component 2 can be relatively simple, and thus it can facilitate the production and manufacturing of the first protruding structure 41, the second protruding structure 42, and the second component 2 as a whole.

[0061] For example, the first protruding structure 41 is integrally formed with the second component 2, and the second protruding structure 42 is integrally formed with the second component 2. To a certain extent, it can enhance the overall structural strength of the second component 2, and the assembly process between the first protruding structure 41, the second protruding structure 42, and the second component 2 can be omitted.

[0062] Referring to Figure 1 , the vehicle according to the second aspect embodiment of the present invention includes the galvanized sheet structural member 100 according to the above first aspect embodiment.

[0063] According to the vehicle of the embodiment of the present utility model, by providing the above-mentioned galvanized steel structural member 100, at least one of the first connecting flange 11 and the second connecting flange 21 of the galvanized steel structural member 100 is formed with a first protruding structure 41, and the first protruding structure 41 is located between the first connecting flange 11 and the second connecting flange 21. When the first component 1 and the second component 2 are welded, the first protruding structure 41 can make there be a certain gap between the first connecting flange 11 and the second connecting flange 21. This part of the gap can facilitate the escape of zinc vapor generated by the first connecting flange 11 or the second connecting flange 21 due to high temperature, and thus can improve the welding connection stability between the first component 1 and the second component 2.
