[0034] Combined with attachment Figure 1 and attached Figure 2 The vehicle side panel reinforcement structure proposed in the present invention includes a main body 100, which is installed in a side panel cavity 200 to increase the structural strength of the side panel cavity 200. The main body 100 includes a first reinforcement member 110, a second reinforcement member 120 and a support member 130. One end of the first reinforcement member 110 is connected to the first body member 210, and the second reinforcement member 120 is connected to the second body member 220. The first body member 210 and the second body member 220 are connected to form the aforementioned side panel cavity 200. One end of the support member 130 is connected to the first reinforcement member 110 and the first body member 210, and the other end is connected to the second reinforcement member 120 and the second body member 220. The first reinforcement member 110, the support member 130 and the second body member 220 cooperate to form a first buffer cavity 200a, and the second reinforcement member 120, the support member 130 and the first body member 210 cooperate to form a second buffer cavity 200b.

[0035] The first reinforcement 110 is connected to the first body member 210 to increase the structural strength and bending stiffness of the first body member 210. The second reinforcement 120 is connected to the second body member 220 to increase the structural strength and bending stiffness of the second body member 220. The support member 130 is connected to the first and second body members 210, 220 at both ends to provide support. The first and second buffer chambers 200a, 200b provide a crumple zone for the first body member 210, reducing the likelihood of the first body member 210 intruding into the vehicle interior during a collision. When the first and second buffer chambers 200a, 200b collapse under the impact of a collision, the support member 130 and the second reinforcement 120 cooperate to prevent the second body member 220 from deforming, reducing the likelihood of the second body member 220 intruding into the vehicle interior. This helps to enhance the overall structural strength of the side panel chamber 200, thereby improving the collision safety of the vehicle.

[0036] For example, the main body 100 is made of aluminum alloy, which can have a certain structural strength.

[0037] For example, the first reinforcement member 110, the second reinforcement member 120 and the support member 130 are integrally formed, as shown in the attached Figure 4 As shown, the cross section of the main body 100 is S-shaped.

[0038] In one example, in conjunction with Figure 2 and attached Figure 3A first connecting rib 140 is provided in the first buffer cavity 200a. More specifically, a first connecting rib 140 is provided on a side of the main body 100 close to the first buffer cavity 200a. The first connecting rib 140 is connected to at least one of the first reinforcement 110 and the support member 130 to increase the structural strength and stability of the main body 100.

[0039] Optionally, as attached Figure 4 As shown, the first connecting rib 140 is arranged between the first reinforcement 110 and the support member 130, and is connected to both the first reinforcement 110 and the support member 130. Such an arrangement can increase the connection strength between the first reinforcement 110 and the support member 130, and ensure the supporting effect of the support member 130 on the first reinforcement 110. When the first body member 210 is subjected to a collision impact, the first connecting rib 140 can cooperate with the first reinforcement 110 and the support member 130 and play a supporting and anti-collision role, which is beneficial to improving the collision performance of the first body member 210, making it difficult for the first body member 210 to invade the first buffer cavity 200a, and can cooperate with the collapse buffering effect of the first buffer cavity 200a to reduce the collision energy transmitted to the second body member 220, making it difficult for the second body member 220 to invade the vehicle interior space.

[0040] Optionally, as attached Figure 3 As shown, a plurality of first connecting ribs 140 are distributed at intervals along the length direction of the main body 100 .

[0041] In one example, the first reinforcement member 110 is connected to the first body member 210 by adhesive bonding, as shown in the attached Figure 1 As shown, the first reinforcement 110 has a glue groove 111 at one end close to the first body part 210 . The glue groove 111 contains connecting glue for connecting the first reinforcement 110 and the first body part 210 .

[0042] Optionally, as attached Figure 1 As shown, a limiting rib 112 is protruded from one end of the first reinforcement 110 close to the first body part 210. The limiting rib 112 is located in the glue groove 111 and is used to cooperate with the connecting glue in the glue groove 111. The connecting glue adopts a glue strip. The limiting rib 112 can limit and clamp the connecting glue to ensure a firm connection between the connecting glue and the first reinforcement 110 and increase the structural stability of the first reinforcement 110.

[0043] Optionally, the limiting rib 112 and the first reinforcement member 110 are integrally formed.

[0044] In one example, in conjunction with Figure 1 and attached Figure 2A second connecting rib 150 is provided in the second buffer cavity 200b. More specifically, a second connecting rib 150 is provided on the side of the main body 100 close to the second buffer cavity 200b. The second connecting rib 150 is connected to at least one of the second reinforcement 120 and the support member 130 to increase the structural strength and stability of the main body 100.

[0045] When the first body part 210 is subjected to a collision impact, the second connecting rib 150 can cooperate with the second reinforcement 120 and the support member 130 to play a supporting and collision-resistant role, which is beneficial to improving the collision performance of the first body part 210, making it difficult for the first body part 210 to invade the interior of the second buffer cavity 200b, and can cooperate with the collapse buffering effect of the second buffer cavity 200b to reduce the collision energy transmitted to the second body part 220, making it difficult for the second body part 220 to invade the interior space of the vehicle.

[0046] Optionally, as attached Figure 4 As shown, the second connecting rib 150 is disposed between the second reinforcement member 120 and the support member 130 , and is connected to both the second reinforcement member 120 and the support member 130 .

[0047] Optionally, as attached Figure 1 As shown, a plurality of second connecting ribs 150 are distributed at intervals along the length direction of the main body 100 .

[0048] In a preferred example, the main body 100 includes both the first connecting rib 140 and the second connecting rib 150 mentioned above.

[0049] In one example, the second reinforcement member 120 is connected to the second body member 220 by adhesive bonding, as shown in the attached Figure 3 As shown, the second reinforcement 120 has a glue groove 111 at one end close to the second body part 220 . The glue groove 111 is used to set a connecting glue to connect the second reinforcement 120 to the second body part 220 through the connecting glue.

[0050] Optionally, as attached Figure 3 As shown, a limiting rib 112 is protruded from one end of the second reinforcement 120 close to the second body part 220. The limiting rib 112 is located in the glue groove 111 and is used to cooperate with the connecting glue in the glue groove 111. The connecting glue adopts a glue strip. The limiting rib 112 can limit and clamp the connecting glue to ensure a firm connection between the connecting glue and the second reinforcement 120 and increase the structural stability of the second reinforcement 120.

[0051] Optionally, the limiting rib 112 and the second reinforcement member 120 are integrally formed.

[0052] Optionally, the second reinforcement 120 is connected to the second body part 220 via a fastener 121 . The fastener 121 is a screw, which, together with the fixing effect of the connecting glue, can improve the connection quality between the second reinforcement 120 and the second body part 220 .

[0053] In one example, as shown in the attached Figure 1 As shown, side seals 160 are provided at both ends of the main body 100 along the length direction. The side seals 160 are connected to the first reinforcement 110, the second reinforcement 120 and the support member 130 along the length direction to increase the structural stability of both ends of the main body 100.

[0054] Optionally, the side sealing member 160 , the first reinforcement member 110 , the second reinforcement member 120 and the support member 130 are integrally formed.

[0055] Optionally, as attached Figure 1 As shown, a positioning member 161 is provided at at least one end of the main body 100 along the length direction. The positioning member 161 is protruded on the side sealing member 160. The positioning member 161 is used to connect with the first body member 210 and / or the second body member 220. A positioning groove that cooperates with the positioning member 161 is provided on the first body member 210 and / or the second body member 220. When the main body 100 is connected to the first body member 210 and the second body member 220, the positioning member 161 is accommodated in the positioning groove to achieve rapid positioning of the main body 100, which is beneficial to improving the installation efficiency of the main body 100.

[0056] Based on the above vehicle side reinforcement structure, as shown in the attached Figure 5 As shown, the present invention also proposes an A-pillar assembly, including an A-pillar outer panel 230, an A-pillar inner panel 240 and the aforementioned main body 100. The A-pillar outer panel 230 and the A-pillar inner panel 240 are connected to form the aforementioned side panel cavity 200, and the main body 100 is installed in the side panel cavity 200.

[0057] By arranging the main body 100 between the A-pillar outer panel 230 and the A-pillar inner panel 240, the overall structural strength and bending stiffness of the A-pillar can be increased, and the problem of excessive overall deformation of the A-pillar affecting the life safety of passengers in a vehicle collision, especially in an offset collision, can be avoided, thereby improving the collision safety of the A-pillar; the arrangement of the main body 100 can not only increase the bending strength of the A-pillar outer panel 230 and the A-pillar inner panel 240 through the first reinforcement 110 and the second reinforcement 120, but also can form the first buffer cavity 200a and the second buffer cavity 200b through the main body 100 to play a collision buffering role, which is beneficial to dispersing the collision energy transmitted to the A-pillar and protecting the life safety of the passengers.

[0058] The existing technology usually increases the cross-sectional area of ​​the A-pillar to ensure the strength of the A-pillar, but this method will cause the obstruction angle of the A-pillar to become larger, expand the blind spot of vision, cause the driver's vision to deteriorate, and affect driving safety. The first reinforcement member 110 and the second reinforcement member 120 are connected by the support member 130. The first reinforcement member 110 and the second reinforcement member 120 are respectively fitted with the A-pillar outer panel 230 and the A-pillar inner panel 240, so as not to occupy a large space. This can not only improve the strength of the A-pillar, but also prevent the size of the A-pillar from being too large. There is no need to increase the overall cross-sectional size of the A-pillar, thereby ensuring the driver's safe driving vision.

[0059] As attached Figure 5 As shown in the coordinate system in , the X, Y, and Z directions in the coordinate system are based on the vehicle coordinate system, where the X direction refers to the direction parallel to the driving direction of the car, that is, the front and rear direction, the Y direction refers to the width direction of the car, and the Z direction refers to the height direction of the car.

[0060] Several first connecting ribs 140 and second connecting ribs 150 are spaced apart along the length direction of the main body 100. When the vehicle is involved in a collision, it can ensure that the A-pillar is not easily bent or deformed in the length direction (roughly along the X direction). The cooperation between the support member 130 and the first connecting ribs 140 and the second connecting ribs 150 can also increase the structural strength of the A-pillar in the Y and Z directions, making the A-pillar less likely to break and providing good support.

[0061] In one example, as shown in the attached Figure 5 As shown, the main body 100 includes a first connecting segment 101 and a second connecting segment 102. The rear end of the first connecting segment 101 is connected to the front end of the second connecting segment 102. The second connecting segment 102 is located at the bending part of the side panel 270, and the second connecting segment 102 is arc-shaped. The strength of the second connecting segment 102 is greater than that of the first connecting segment 101.

[0062] Optionally, in combination with Figure 2 and attached Figure 3 The second connecting section 102 includes a third connecting rib 151, which is arranged in the first buffer cavity 200a, and the third connecting rib 151 is connected to at least one of the first reinforcement 110 and the support member 130. The third connecting rib 151 cooperates with the first connecting rib 140 to increase the strength of the second connecting section 102, so that the strength of the second connecting section 102 is greater than the strength of the first connecting section 101.

[0063] Optionally, in combination with Figure 1 and attached Figure 2The second connecting section 102 includes a third connecting rib 151, which is arranged in the second buffer cavity 200b and is connected to at least one of the second reinforcement 120 and the support member 130. The third connecting rib 151 cooperates with the second connecting rib 150 to increase the strength of the second connecting section 102, so that the strength of the second connecting section 102 is greater than that of the first connecting section 101.

[0064] Optionally, the third connecting rib 151 is a V-shaped rib to significantly improve the structural stability of the second connecting section 102 .

[0065] In a preferred example, the third connecting rib 151 is disposed in both the first buffer cavity 200 a and the second buffer cavity 200 b .

[0066] Since the span of the A-pillar is long, it is easy to bend and deform in a collision accident, affecting the stability of the vehicle side. Therefore, the strength of the second connecting section 102 is increased by the third connecting rib 151 to make its structure stable and not easily deformed to invade the space inside the vehicle, thereby ensuring the safety of the passengers.

[0067] In one example, in conjunction with Figure 2 and attached Figure 6 The A-pillar assembly proposed in the present invention also includes a reinforcing beam 170 arranged between the door inner panel 250 and the door window frame reinforcement plate 260. The door inner panel 250 and the door window frame reinforcement plate 260 are connected to form an accommodating cavity. The reinforcing beam 170 is installed in the accommodating cavity, and the reinforcing beam 170 is connected to at least one of the door inner panel 250 and the door window frame reinforcement plate 260. The reinforcing beam 170 is used to increase the structural strength of the door window frame side.

[0068] Optionally, as attached Figure 2 As shown, the reinforcement beam 170 is connected to the vehicle door window frame reinforcement plate 260 , for example, by riveting.

[0069] Optionally, a buffer gap is left between the reinforcement beam 170 and the door inner panel 250 .

[0070] In one alternative, the reinforcement beam 170 is a solid beam body. In another alternative, as shown in the attached Figure 6 As shown, the reinforcing beam 170 adopts a hollow beam body, and the reinforcing beam 170 includes a cavity 171. The cavity 171 is open at at least one end in the length direction of the reinforcing beam 170. The cavity 171 can play a role in collapse and buffering. When the vehicle collides, especially when an offset collision occurs, the door side is subjected to the collision impact, and the door window frame reinforcement plate 260 is not easily broken under the support of the reinforcing beam 170.

[0071] Optionally, a partition 172 is provided in the cavity 171, which extends along the length direction of the reinforcing beam 170 and divides the cavity 171 into at least two chambers. The partition 172 can ensure the structural stability of the reinforcing beam 170, and at least two chambers can absorb collision energy.

[0072] Optionally, the reinforcement beam 170 is made of an aluminum alloy profile beam.

[0073] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
