Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0025] In the description of the embodiments of this application, the first direction X, the second direction Y, and the third direction Z are introduced to more clearly describe the vehicle trunk structure 100. The first direction X corresponds to the width direction of the vehicle 10, i.e., the left-right direction; the second direction Y is the length direction of the vehicle 10, i.e., the front-back direction; and the third direction Z is the height direction of the vehicle 10. In the description of this application, "front" refers to a position closer to the front of the vehicle 10, "rear" refers to a position closer to the rear of the vehicle 10; "up" refers to a position closer to the top of the vehicle 10, and "down" refers to a position closer to the bottom of the vehicle 10.

[0026] This application provides a vehicle trunk structure 100, which can significantly improve the rigidity of the panel in the trunk area, improve collision performance, and also ensure structural installation.

[0027] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The vehicle luggage compartment structure 100 of this application embodiment includes: panel body 110, first reinforcing member 120, second reinforcing member 130 and third reinforcing member 140.

[0028] The panel body 110, as the basic load-bearing component of the luggage compartment, adopts a large-area sheet metal structure. Its overall shape is roughly "U"-shaped and adapts to the installation space dimensions of the luggage compartment of vehicle 10. Its material can be high-strength steel or aluminum alloy, ensuring lightweight while providing basic load-bearing capacity. The panel body 110 has opposing upper surfaces 115 and lower surfaces 116. The upper surface 115 is used to connect with the third reinforcing member 140, while the lower surface 116 is used to assemble the first reinforcing member 120 and the second reinforcing member 130. Furthermore, the edges of the panel body 110 are provided with connecting edges adapted to the vehicle 10's body frame, allowing its overall structure to be stably integrated into the vehicle 10's body frame.

[0029] like Figure 2 and Figure 3 As shown, the first reinforcing member 120 can be configured as a long strip-shaped reinforcing beam structure, which can be fixed to the lower surface 116 of the panel body 110 by welding, bolting, or structural adhesive bonding. Please refer to the diagram. Figure 4 , Figure 5 and Figure 6 The cross-sectional shape of the first reinforcing member 120 can be approximately "U"-shaped or U-shaped, and this shape can form a first reinforcing cavity 150 with the lower surface 116 of the panel body 110. The first reinforcing member 120 can provide effective support for one side area of ​​the panel body 110.

[0030] The second reinforcing member 130 has a similar structure to the first reinforcing member 120 and can also be configured as a long strip-shaped reinforcing beam. It can be fixed to the lower surface 116 of the panel body 110 using the same connection method as the first reinforcing member 120. The second reinforcing member 130 and the first reinforcing member 120 are spaced apart along the first direction X. The spacing can be determined based on the width of the vehicle 10's trunk, ensuring it covers the main stress-bearing area of ​​the lower surface 116 of the panel body 110. The second reinforcing member 130 and the lower surface 116 of the panel body 110 form a second reinforcing cavity 160. The cross-sectional shape of this cavity is similar to that of the first reinforcing cavity 150, and is approximately U-shaped.

[0031] The third reinforcing member 140 covers the upper surface 115 of the panel body 110. The third reinforcing member 140 cooperates with the upper surface 115 of the panel body 110 to form a plurality of independent third reinforcing cavities 170. The plurality of third reinforcing cavities 170 are linearly arranged along the first direction X and are arranged as a whole between the projection areas of the first reinforcing cavity 150 and the second reinforcing cavity 160 on the panel body 110.

[0032] The vehicle's trunk structure 100 forms a multi-cavity structure through the cooperation of the panel body 110 with the first reinforcing member 120, the second reinforcing member 130, and the third reinforcing member 140. On one hand, the first reinforcing cavity 150, the second reinforcing cavity 160, and the multiple third reinforcing cavities 170 effectively improve the overall rigidity of the panel body 110, solving the technical problem of insufficient rigidity in large-area thin panels. Furthermore, the third reinforcing cavities 170 are arranged between the first reinforcing cavities 150 and the second reinforcing cavities 160, thus strengthening the central area of ​​the panel body 110 and preventing weak rigidity due to lack of support, resulting in a more uniform rigidity distribution. On the other hand, by setting multiple cavity structures, rigidity can be improved without increasing the thickness of the panel or reinforcing members, allowing for control of the overall weight while maintaining rigidity, meeting the lightweight requirements of the vehicle 10. Simultaneously, in the event of a collision, the cavity deformation can absorb collision energy, reducing the transmission of impact to the passenger compartment and improving collision safety.

[0033] like Figure 2 and Figure 6As shown, in some embodiments, the first reinforcing member 120 includes a first side portion 121, a second side portion 122, and a first main body portion 123. The first side portion 121 is a strip-shaped structure on the side of the first reinforcing member 120 closer to the second reinforcing member 130. It has at least a part that fits with the panel body 110, and the connection stability is improved through surface contact, so that the force between the first reinforcing member 120 and the panel body 110 can be evenly transmitted, reducing local stress concentration. The second side portion 122 is arranged at an interval from the first side portion 121 on the side away from the second reinforcing member 130 along the first direction X. That is, the second side portion 122 is a strip-shaped structure on the side of the first reinforcing member 120 farther from the second reinforcing member 130, and it has at least a part that fits with the panel body 110. The first main body portion 123 is arranged between the first side portion 121 and the second side portion 122 and is connected to both of them respectively. The first main body portion 123 protrudes downward along the third direction Z relative to the first side portion 121 and the second side portion 122, so that the cross-section of the first reinforcing member 120 is generally in a concave "ji" - shaped structure.

[0034] Correspondingly, the panel body 110 includes a first protruding portion 111 that protrudes toward the first main body portion 123 along the third direction Z. The first protruding portion 111 can be a protruding structure formed by stamping the panel body 110 itself, and its protruding direction is the same as that of the first main body portion 123, both protruding downward along the third direction Z. Thus, the first reinforcing cavity 150 formed by the first protruding portion 111 and the first main body portion 123 is generally in a U-shaped structural cavity as Figure 6 shown, which can effectively improve the structural strength of the cavity.

[0035] As Figure 2 and Figure 6 shown, in some embodiments, the first side portion 121 includes a first overlapping portion 124. The first overlapping portion 124 is used to overlap with the panel body 110. Specifically, the upper side surface of the first overlapping portion 124 close to the panel body 110 is closely fitted with the lower surface 116 of the panel body 110. The third reinforcing member 140 includes a second overlapping portion 141, and the second overlapping portion 141 corresponds to the first overlapping portion 124 along the third direction Z. The second overlapping portion 141, the panel body 110, and the first overlapping portion 124 are overlapped in sequence along the third direction Z. By forming a three-layer overlapping structure through the overlapping connection of the first overlapping portion 124, the panel body 110, and the second overlapping portion 141, the structural strength of the transition connection area on the side of the first reinforcing member 120 close to the second reinforcing member 130 can be improved.

[0036] In some embodiments, the third reinforcing member 140 further includes a second protruding portion 142 and a side suspended portion 143, both of which can be formed by a stamping and integral molding process on the third reinforcing member 140. The second protruding portion 142 is connected to one side of the second overlapping portion 141, and the side suspended portion 143 is connected to the side of the second protruding portion 142 away from the second overlapping portion 141.

[0037] Along the third direction Z, the second protruding portion 142 protrudes upward relative to the second overlapping portion 141 and the side suspended portion 143, that is, the protruding direction of the second protruding portion 142 is opposite to that of the first protruding portion 111, so that there is a preset gap between the lower surface of the second protruding portion 142 and the upper surface 115 of the first protruding portion 111, that is, the second protruding portion 142 is suspended above the first protruding portion 111. The second protruding portion 142 and the side suspended portion 143 are both located above the first protruding portion 111. The side suspended portion 143 is supported on one side by the second protruding portion 142 to form a suspended state and is integrally suspended above the first protruding portion 111. This can meet the installation requirements of the countermounting member, improve the structural strength of the third reinforcing member 140, and also enhance the lateral stability of the third reinforcing member 140.

[0038] In addition, the three-layer overlapping structure formed by the first overlapping portion 124, the panel body 110, and the second overlapping portion 141 is located on the right side (the side close to the second reinforcing member 130) of the suspended area formed by the second protruding portion 142 and the side suspended portion 143, which can effectively improve the structural stability and rigidity at the suspended area.

[0039] As Figure 2 and Figure 6 shown, in some embodiments, the second reinforcing member 130 includes a third side portion 131, a fourth side portion 132, and a second main body portion 133. The third side portion 131 and the fourth side portion 132 are support units on both sides of the second reinforcing member 130 for connecting to the panel body 110. Both are substantially strip-shaped structures extending along the second direction Y. At least part of the upper side surfaces of the third side portion 131 and the fourth side portion 132 are in contact with the lower surface 116 of the panel body 110. Among them, the fourth side portion 132 is arranged at an interval along the first direction X on the side of the fourth side portion 132 away from the first reinforcing member 120. The second main body portion 133 is arranged between the third side portion 131 and the fourth side portion 132 and protrudes downward along the third direction Z relative to the third side portion 131 and the fourth side portion 132.

[0040] Specifically, the third side portion 131, the fourth side portion 132, and the second main body portion 133 can be integrally formed on the second reinforcing member 130 by a stamping process. Its cross section is generally in the shape of a concave "ji" character as Figure 6 shown.

[0041] Correspondingly, the panel body 110 includes a third protrusion 112 that protrudes towards the second main body portion 133 along the third direction Z. The protrusion direction of the third protrusion 112 is consistent with that of the second main body portion 133, and it also protrudes downward along the third direction Z. Therefore, the second reinforcing cavity 160 formed by the third protrusion 112 and the second main body portion 133 is approximately U-shaped, which can effectively improve the strength and structural stability of the cavity structure.

[0042] like Figure 2 and Figure 6 As shown, in some embodiments, the third side portion 131 includes a third overlapping portion 134. The third overlapping portion 134 is used to overlap with the panel body 110. Specifically, the upper surface of the third overlapping portion 134 near the panel body 110 is in close contact with the lower surface 116 of the panel body 110. Correspondingly, the third reinforcing member 140 includes a fourth overlapping portion 148, which corresponds to the third overlapping portion 134 along the third direction Z. The fourth overlapping portion 148, the panel body 110, and the third overlapping portion 134 overlap sequentially. By stacking and connecting the third overlapping portion 134, the panel body 110, and the fourth overlapping portion 148 to form a three-layer overlapping structure, the structural strength of the transition connection area of ​​the second reinforcing member 130 near the first reinforcing member 120 can be improved.

[0043] Please refer to it again. Figure 5 In some embodiments, along the third direction Z, the first reinforcing cavity 150 has a first dimension H1, and the second reinforcing cavity 160 has a second dimension H2, wherein the second dimension H2 is greater than or equal to the first dimension H1. Specifically, when the second dimension H2 of the second reinforcing cavity 160 is greater than the first dimension H1 of the first reinforcing cavity 150, a height difference is formed between the second reinforcing cavity 160 and the first reinforcing cavity 150, which can effectively improve the structural strength and stability of the entire frame. Wherein, the first dimension H1 is the distance between the lower surface 116 of the first protrusion 111 and the upper surface of the first main body 123, and the second dimension H2 is the distance between the lower surface 116 of the third protrusion 112 and the upper surface of the second main body 133.

[0044] Please refer to it again. Figure 6 In some embodiments, the panel body 110 includes a fourth protrusion 113 and a fifth protrusion 114 connected to each other. The fourth protrusion 113 and the fifth protrusion 114 are located between the first reinforcing member 120 and the second reinforcing member 130. The fourth protrusion 113 protrudes downward along a third direction Z, and the fifth protrusion 114 is disposed on the side of the fourth protrusion 113 near the second reinforcing member 130, and in the opposite direction to the protrusion of the fourth protrusion 113, that is, the fifth protrusion 114 protrudes upward along a third direction Z.

[0045] Correspondingly, the third reinforcing member 140 includes a sixth protrusion 1412 and a seventh protrusion 1413 connected to each other. The sixth protrusion 1412 protrudes downward along the third direction Z, and the seventh protrusion 1413 is connected to the side of the sixth protrusion 1412 near the second reinforcing member 130. The protrusion directions of the sixth protrusion 1412 and the seventh protrusion 1413 are opposite, that is, the seventh protrusion 1413 protrudes in the third direction Z. The fourth protrusion 113 and the sixth protrusion 1412 are in contact, and a third reinforcing cavity 170 is formed on both sides of the contact position. That is, the lower surface 116 of the sixth protrusion 1412 is attached to the upper surface of the fourth protrusion 113, forming a third reinforcing cavity 170 on both sides, forming an inclined structural cavity, which can effectively strengthen the structural rigidity of the middle area of ​​the panel body 110.

[0046] The fifth protrusion 114 and the seventh protrusion 1413 come into contact, and a third reinforcing cavity 170 is formed on both sides of the contact position. That is, the upper surface of the fifth protrusion 114 is attached to the lower surface 116 of the seventh protrusion 1413, forming a third reinforcing cavity 170 on both sides, which also forms an inclined structural cavity, effectively strengthening the structural rigidity of the middle area of ​​the panel body 110.

[0047] Furthermore, along the first direction X, the aforementioned three-layer overlapping structure is provided on both sides of the fourth protrusion 113, the fifth protrusion 114, the sixth protrusion 1412 and the seventh protrusion 1413, which can further enhance the structural strength of the reinforced transition connection area and improve the strength of the entire vehicle luggage compartment structure 100.

[0048] Please refer to the following: Figure 7 and Figure 8 The second side portion 122 of the first reinforcing member 120 and the panel body 110 are both provided with concave and convex structures, and the two concave and convex structures are in contact with each other and form inclined structural cavities on both sides along the second direction Y at the contact position, which effectively strengthens the structural rigidity of the area.

[0049] like Figure 9 As shown, in some embodiments, along the second direction Y, the front end of the first reinforcing cavity 150 is provided with a first opening 151, and the rear end is closed. That is, along the second direction Y, the front end of the first reinforcing cavity 150 is in an open state, forming the first opening 151, and the rear end of the first reinforcing cavity 150 is tightly fitted with the lower surface 116 of the panel body 110 through the rear end extension structure of the first reinforcing member 120 to form a closed structure, so that the rear end of the first reinforcing cavity 150 forms a completely closed cavity structure. This can improve the structural strength of the collision contact area.

[0050] Please refer to it again. Figure 9, in some embodiments, the third reinforcing member 140 further includes a first front-end overhang portion 144, a first rear-end overhang portion 145, and a first contact portion 146. The first contact portion 146 and the side overhang portion 143 are arranged alternately along the second direction Y, and are both disposed between the first front-end overhang portion 144 and the first rear-end overhang portion 145; the first front-end overhang portion 144 and the first rear-end overhang portion 145 are respectively connected to the first contact portion 146. Specifically, both the first front-end overhang portion 144 and the first rear-end overhang portion 145 are翘曲 upward relative to the main body portion of the third reinforcing member 140, so as to be spaced apart from the panel body 110, forming a suspended area, which can further improve the structural stability.

[0051] As Figure 10 shown, in some embodiments, the first side portion 121 further includes at least one first bending portion 125. The first bending portion 125 and the first overlapping portion 124 are arranged alternately along the second direction Y. A fourth reinforcing cavity 180 is defined between each first bending portion 125 and the panel body 110. Correspondingly, the third reinforcing member 140 further includes at least one second bending portion 147. The second bending portion 147 and the second overlapping portion 141 are arranged alternately along the second direction Y. Each second bending portion 147 and each first bending portion 125 are disposed on opposite sides of the panel body 110 along the third direction Z, and a fifth reinforcing cavity 190 is defined between each second bending portion 147 and the panel body 110. The fourth reinforcing cavity 180 and the fifth reinforcing cavity 190 are correspondingly arranged and fastened together up and down, forming a plurality of "day" - shaped cavity structures as Figure 10 shown, and the transition area between the cavity and the overlapping position is smoothly transitioned in an arc - shaped step, improving the collision performance. Especially the cavity near the rear end tail can further improve the collision performance.

[0052] As Figure 11 shown, in some embodiments, the third side portion 131 further includes at least one third bending portion 135. The third bending portion 135 and the third overlapping portion 134 are arranged alternately along the second direction Y. A sixth reinforcing cavity 200 is defined between each third bending portion 135 and the panel body 110. The third reinforcing member 140 further includes at least one fourth bending portion 149. The fourth bending portion 149 and the fourth overlapping portion 148 are arranged alternately along the second direction Y. Each fourth bending portion 149 and each third bending portion 135 are disposed on opposite sides of the panel body 110 along the third direction Z, and a seventh reinforcing cavity 210 is defined between each fourth bending portion 149 and the panel body 110. The sixth reinforcing cavity 200 and the seventh reinforcing cavity 210 are correspondingly arranged and fastened together up and down, forming a plurality of "day" - shaped cavity structures as Figure 10 shown, and the transition area between the cavity and the overlapping position is smoothly transitioned in an arc - shaped step, improving the collision performance. Especially the cavity near the rear end tail can further improve the collision performance.

[0053] Please refer to it again. Figure 11 In some embodiments, the third reinforcing member 140 further includes a second front-end suspended portion 1410 and a second rear-end suspended portion 1411, with a fourth bending portion 149 and a fourth overlapping portion 148 both disposed between the second front-end suspended portion 1410 and the second rear-end suspended portion 1411; the second front-end suspended portion 1410 and the second rear-end suspended portion 1411 are respectively connected to the fourth overlapping portion 148. Specifically, the second front-end suspended portion 1410 and the second rear-end suspended portion 1411 are both curved upward relative to the main body of the third reinforcing member 140, thereby spacing them from the panel body 110 to form a suspended area, which can further improve structural stability.

[0054] like Figure 12 As shown, along the second direction Y, the front end of the second reinforcing cavity 160 is provided with a second opening 161, and the rear end is closed. That is, along the second direction Y, the front end of the second reinforcing cavity 160 is in an open state, forming the second opening 161, and the rear end of the second reinforcing cavity 160 is tightly fitted with the lower surface 116 of the panel body 110 through the rear end extension structure of the second reinforcing member 130 to form a closed structure, so that the rear end of the second reinforcing cavity 160 forms a completely closed cavity structure. This can improve the structural strength of the collision contact area.

[0055] Please refer to the following: Figure 13 and Figure 14 As shown, in the third direction Z, the orthographic projection of the third reinforcing member 140 partially overlaps with the orthographic projections of the first reinforcing member 120 and the second reinforcing member 130. The three form a frame structure beam, with an overall cross-section that is concave-convex, working together to enhance the structural strength of the suitcase.
