Description

Technical Field

[0001] This invention relates to the field of vehicle components, and more particularly to a luggage compartment sheet metal structure and a vehicle, specifically to a luggage compartment sheet metal structure that can improve sealing performance, an assembly method, and a vehicle. Background Technology

[0002] The vehicle's trunk is located at the rear of the vehicle and consists of a trunk lid and a sheet metal structure, forming the basis for the overall design of the trunk.

[0003] Existing vehicle trunk sheet metal structures are typically formed by combining three metal plates: an outer rear plate, an inner rear plate, and a taillight support plate. The outer rear plate, inner rear plate, and taillight support plate each form a flange structure created by recesses extending from their respective main bodies towards the front of the vehicle. For example... Figure 1 As shown, to ensure the vehicle's aesthetics, the flange of the upper taillight support plate 30 and the flange of the lower outer rear plate 10 are smoothly connected. Figure 2 and Figure 3 As shown, the inner rear panel 20 is sandwiched between the outermost outer rear panel 10 and the innermost taillight support plate 30. At this time, a cavity 40 exists in the overlapping area of ​​the outer rear panel 10, the inner rear panel 20, and the taillight support plate 30. That is, the cavity 40 is formed in the overlapping area of ​​the flanges of the outer rear panel 10, the inner rear panel 20, and the taillight support plate 30, and this overlapping area is precisely the area used for welding and fixing the outer rear panel 10, the inner rear panel 20, and the taillight support plate 30. When this flange area is sealed with a sealing strip, it is not possible to completely prevent external dust or water from entering the vehicle interior through the cavity 40.

[0004] In the prior art, in order to prevent water from entering the cavity, the common method is to add foam blocks to block the cavity, or to adjust the position or size of each sheet metal piece. However, the above-mentioned existing methods will result in additional manufacturing costs and time costs. Summary of the Invention

[0032] Figure 4 This is a schematic diagram showing the flange area of ​​the sheet metal structure of a suitcase according to an embodiment of the present invention; Figure 5 This is a schematic diagram showing the inner side of the outer rear panel according to an embodiment of the present invention; Figure 6 This is a cross-sectional view showing a luggage sealing strip according to an embodiment of the present invention.

[0033] The luggage box sheet metal structure according to an embodiment of the present invention includes an outer rear panel 11, an inner rear panel 21, a taillight support plate 31, and a luggage box sealing strip 50.

[0034] Specifically, the outer rear panel 11 includes an integrally formed outer rear panel body 112 and an outer rear panel flange portion 111. The outer rear panel flange portion 111 is recessed from the edge of the outer rear panel body 112 toward the front of the vehicle, and its recess degree corresponds to the edge contour of the vehicle's trunk.

[0035] Furthermore, the outer rear plate flange portion 111 is divided along its edge into a first flange region 1111 and a second flange region 1112. Correspondingly, the outer rear plate body 112 is divided into a first body region 1121 and a second body region 1122, corresponding to the first flange region 1111. Referring to the accompanying drawings, the first flange region 1111 and the first body region 1121 are located in relatively lower areas of the outer rear plate 11, while the second flange region 1112 and the second body region 1122 are located in relatively upper areas of the outer rear plate 11.

[0036] The inner rear panel 21 is located inside the outer rear panel 11 and is joined to the outer rear panel 11. Specifically, the inner rear panel 21 includes an integrally formed inner rear panel body 212 and an inner rear panel flange portion 211. The inner rear panel flange portion 211 is recessed from the edge of the inner rear panel body 212 toward the front of the vehicle. Since the inner rear panel 21 overlaps and joins with the outer rear panel 11 inside the outer rear panel 11, the degree of recess of the flange portion of the inner rear panel 21 corresponds to the degree of recess of the outer rear panel 11, and the flange portion of the inner rear panel 21 overlaps and joins with the flange portion of the outer rear panel 11 in the first flange region 1111 of the outer rear panel 11.

[0037] The taillight support plate 31 is located inside the outer rear panel 11 and the inner rear panel 21, and is combined with the outer rear panel 11 and the inner rear panel 21. Specifically, the taillight support plate 31 includes an integrally formed taillight support plate body 312 and a taillight support plate flange portion 311. The taillight support plate flange portion 311 is formed from the edge of the taillight support plate body 312 and includes the integrally formed taillight support plate body 312 and recessed from the taillight support plate body 312 towards the front of the vehicle. The degree of recess corresponds to the outer rear panel flange portion 111 and the inner rear panel flange portion 211, so that the flange area in the luggage compartment sheet metal structure according to the embodiment of the present invention can correspond to the edge contour of the luggage compartment lid. Furthermore, the taillight support plate flange portion 311 and the outer rear panel flange portion 111 overlap and are combined in the second flange area 1112 of the outer rear panel 11.

[0038] Furthermore, the inner rear panel body 212 and the outer rear panel body 112 overlap and are joined together in the first main body area 1121 of the outer rear panel 11, and the taillight support plate body 312 and the outer rear panel body 112 overlap and are joined together in the second main body area 1122. In addition, as described above, the inner rear panel flange portion 211 and the outer rear panel flange portion 111 overlap and are joined together in the first flange area 1111, and the taillight support plate flange portion 311 and the outer rear panel flange portion 111 overlap and are joined together in the second flange area 1112. Therefore, the taillight support plate 31 and the outer rear panel 11 overlap and are joined together in a relatively upper position in the outer rear panel 11, and the inner rear panel 21 and the outer rear panel 11 overlap and are joined together in a relatively lower position in the outer rear panel 11.

[0039] Optionally, the taillight support plate body 312 may further include a taillight support plate extension portion extending from the second body region 1122 to the first body region 1121 of the outer rear panel 11. Since the inner rear panel 21 and the outer rear panel overlap in the first body region 1121, the portion of the taillight support plate body 312 extending into the first body region 1121 covers the inner rear panel 21, so that the area where the extension portion is located in the first body region 1121 is formed by the outer rear panel body 112, the inner rear panel body 212, and the taillight support plate body 312 overlapping.

[0040] Optionally, the inner rear panel body 212 may further include an inner rear panel extension portion extending from the first body region 1121 to the second body region 1122 of the outer rear panel 11. Since the taillight support plate 31 and the outer rear panel overlap and combine in the second body region 1122, the portion of the inner rear panel body 212 extending into the second body region 1122 is located between the outer rear panel body and the taillight support plate body, so that the area where the extension portion is located in the second body region 1121 is overlapped and combined by the outer rear panel body 112, the inner rear panel body 212 and the taillight support plate body 312.

[0041] Furthermore, since the inner rear panel flange portion 211 and the outer rear panel flange portion 111 overlap and are joined in the first flange region 1111, and the taillight support plate flange portion 311 and the outer rear panel flange portion 111 overlap and are joined in the second flange region 1112, the outer rear panel flange portion 111 region is always formed by only two overlapping plates, thus avoiding the presence of cavities as described in the prior art. Therefore, it is possible to prevent external water or dust from entering the vehicle body through cavities. Optionally, the width of the inner rear panel flange portion 211 can be smaller than the width of the outer rear panel flange portion 111.

[0042] In addition, according to an embodiment of the present invention, the luggage compartment sealing strip 50 is used to seal the integral flange area formed by at least one of the outer rear panel flange portion 111, the inner rear panel flange portion 211, and the taillight support bracket flange portion.

[0043] Specifically, the luggage compartment sealing strip 50 may include a sealing strip body 51 and a sealing portion 52 connected to the sealing strip body 51. The luggage compartment sealing strip 50 seals the flange area by inserting the flange area into the sealing portion 52. The sealing portion 52 may further include: a plurality of clamping portions 521 extending obliquely from the inner surface of the sealing portion 52 toward the sealing strip body 51, thereby clamping the flange area assembled to the luggage compartment sealing strip 50 and fixing it in the sealing portion 52 by clamping force and friction; and sealant 522 formed on the innermost side of the sealing portion 52. When the flange area is inserted into the innermost side of the sealing portion 52, the sealant 522 further seals the edge of the flange area, thereby ensuring the sealing performance of the luggage compartment sheet metal structure.

[0044] On the other hand, the present invention also provides a method for assembling a luggage box sheet metal structure according to the above embodiments. Specifically, the assembly method includes: step S1: firstly, welding the outer rear panel 11 and the inner rear panel 21 together to form a rear panel assembly; step S2: welding the rear panel assembly, which combines the outer rear panel and the inner rear panel 21, to the taillight support plate 31; and step S3: assembling the luggage box sealing strip 50 along a flange area formed by at least one of the outer rear panel flange, the inner rear panel flange, and the taillight support plate flange. The specific joining positions of the above assembly method are referred to the above embodiments and will not be described in detail again.

[0045] Furthermore, the present invention also provides a vehicle that includes a luggage compartment sheet metal structure according to an embodiment of the present invention, thereby ensuring the sealing performance of the luggage compartment sheet metal structure while saving adjustment time of the sheet metal and reducing the use of sealing foam.

[0046] In summary, the present invention provides a luggage compartment sheet metal structure, comprising: an outer rear panel, including an integrally formed outer rear panel body and an outer rear panel flange portion recessed from the outer rear panel body toward the front of the vehicle, wherein the outer rear panel flange portion is divided into a first flange area and a second flange area along its edge, and the outer rear panel body is divided into a first main body area corresponding to the first flange area and a second main body area corresponding to the second flange area; an inner rear panel, attached to the inner side of the outer rear panel, including an integrally formed inner rear panel body and an inner rear panel flange portion recessed from the inner rear panel body toward the front of the vehicle, wherein the inner rear panel flange portion overlaps with the first flange area of ​​the outer rear panel flange portion; a taillight support plate, located on the inner side of the outer rear panel, and including an integrally formed taillight support plate body and a taillight support plate flange portion recessed from the taillight support plate body toward the front of the vehicle, wherein the taillight support plate flange portion overlaps with the second flange area of ​​the outer rear panel flange portion; and a luggage compartment sealing strip, assembled along the edges of the outer rear panel flange portion, the inner rear panel flange portion, and the taillight support plate flange portion.
