[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] See the figure below for reference Figure 1-Figure 4 A body side panel 100 according to an embodiment of the present invention is described. The body side panel 100 can be applied to a vehicle.

[0032] Combination Figure 1-Figure 3As shown, the vehicle body side 100 according to the embodiment of the utility model can mainly include: a side panel 10, a B-pillar inner panel 20, a metal reinforcement 60 and a filling structure 30, wherein the B-pillar inner panel 20 is arranged on the inner side of the side panel 10, and the B-pillar inner panel 20 is at least partially spaced from the side panel 10. Specifically, the B-pillar is the main supporting structure of the vehicle passenger compartment, and the side panel 10 is arranged on the outer side of the B-pillar inner panel 20, which can ensure the smoothness of the vehicle surface and help reduce the reverse airflow generated when the vehicle is driving. A gap is provided between the B-pillar inner panel 20 and the side panel 10, and a certain cavity structure can be formed in the vehicle body side 100. The cavity structure can absorb vibration and help improve the comfort in the vehicle passenger compartment. In the embodiment of the utility model, the cavity structure formed by the B-pillar inner panel 20 and the side panel 10 can provide a location for the filling structure 30 and the metal reinforcement 60. It should be noted that the inner side of the side panel 10 is the side of the side panel 10 close to the passenger compartment.

[0033] Furthermore, the metal reinforcement 60 is disposed between the side panel 10 and the inner panel of the B-pillar, which can not only strengthen the B-pillar of the vehicle, but also integrate hinges and mounting holes to facilitate the installation and connection of the vehicle door and other structures with the B-pillar.

[0034] Furthermore, a filling structure 30 is provided between the B-pillar inner panel 20 and the side panel 10. The filling structure 30 includes a frame member 31 and a foam member 32. The frame member 31 can provide a setting position for the foam member 32, so that the foam member 32 can be fixed at a preset position between the B-pillar inner panel 20 and the side panel 10 to fill the position between the B-pillar inner panel 20 and the side panel 10 that needs to be strengthened. The foam member 32 can foam and expand, and the expanded foam member 32 can be bonded to the B-pillar inner panel 20 and the side panel 10, so that the B-pillar inner panel 20 and the side panel 10 can be in contact with the foam member 32. The material of the foam member 32 in the embodiment of the utility model includes but is not limited to at least one of epoxy resin, foaming agent, curing agent and special additives, so that the foam member 32 can absorb vibration and isolate noise between the B-pillar inner panel 20 and the side panel 10. In addition, after the foaming member 32 is bonded to the B-pillar inner panel 20 and the side panel 10 , the airflow between the B-pillar inner panel 20 and the side panel 10 can be blocked, thereby reducing noise.

[0035] Furthermore, when the filling structure 30 is arranged between the side panel 10 and the inner panel of the B-pillar, the filling structure 30 and the metal reinforcement 60 at least partially overlap each other. In this way, not only can the filling structure 30 and the metal reinforcement 60 simultaneously play a supporting and reinforcing role between the inner panel of the B-pillar and the side panel 10, so as to improve the anti-top pressure and side collision capability of the vehicle B-pillar, but also after adding the filling structure 30, the size of the vehicle B-pillar can be prevented from increasing, thereby facilitating the structural compactness of the vehicle.

[0036] Furthermore, the foaming member 32 is at least partially bonded to the metal reinforcement 60 after foaming and expansion, which can enhance the connection reliability between the filling structure 30 and the metal reinforcement 60 between the B-pillar inner panel 20 and the side panel 10, thereby ensuring the structural reliability of the vehicle's B-pillar.

[0037] Combination Figure 1 and Figure 3 As shown, the width of one end portion of the filling structure 30 in the length direction is increased, and the end portion is arranged at the upper end of the B-pillar. This can improve the top compression resistance of the filling structure 30, enable the filling structure 30 to better bear the collision force, and thus further improve the collision safety of the vehicle.

[0038] With such arrangement, on the one hand, when a vehicle collides, the impact force is transmitted from the side panel 10 to the B-pillar inner panel 20 through the foam member 32, and the foam member 32 absorbs the impact force, which can reduce the force transmitted to the B-pillar inner panel 20, thereby improving the anti-collision ability of the B-pillar inner panel 20. Similarly, the overlapped portion of the metal reinforcement 60 and the filling structure 30 can allow part of the foam to absorb the impact force on the metal reinforcement 60, thereby improving the force bearing capacity of the metal reinforcement 60, and allowing the metal reinforcement 60 to resist greater impact force. In this way, the damage to the occupants in the vehicle when the vehicle collides can be reduced. On the other hand, the foam member 32 can also absorb the vibration caused by road excitation, which can effectively reduce the noise in the vehicle environment, thereby improving the comfort in the passenger compartment.

[0039] Furthermore, the filling structural member 30 can be arranged in the position of the body side panel 100 including but not limited to between the inner panel 20 of the B-pillar and the side panel 10 of the vehicle, between the inner panel of the A-pillar 40 and the side panel 10, and between the rocker beam 50 and the side panel 10. This can not only improve the rigidity and strength of the body side panel 100, but also isolate and reduce noise, which is beneficial to improving the NVH performance of the vehicle.

[0040] In the embodiment of the utility model, the filling structure 30 is a secondary injection molded part. After welding and assembly, painting and baking are performed to make the foaming part 32 foam and expand. The baking temperature includes but is not limited to 138°C, 139°C, 140°C, 141°C and 142°C, and the baking time includes but is not limited to 18 minutes, 19 minutes, 20 minutes, 21 minutes and 22 minutes.

[0041] Furthermore, compared with the body side 100 using a sheet metal structure in the prior art, the foam part 32 has a simple structure and is lighter in weight, which not only reduces the number of parts, saves development costs and shortens the development cycle, but also helps to improve the lightweight of the entire vehicle.

[0042] Combination Figure 1 and Figure 2 As shown, the portion of the metal reinforcement 60 that overlaps with the filling structure 30 is an overlap portion 61, which is located at the upper part of the metal reinforcement 60, and is located on the side of the filling structure 30 facing the side panel 10, and is bonded to the foamed expanded foam member 32. Specifically, the metal reinforcement 60 partially overlaps with the filling structure 30. In the embodiment of the utility model, the filling structure 30 is mainly used to improve the safety performance of the B-pillar facing top pressure and side collision, and the metal reinforcement 60 is not only used to strengthen the structural strength of the B-pillar, but also used to integrate the hinge and the installation hole.

[0043] Such arrangement, on the one hand, can ensure that the filling structure 30 partially overlaps with the metal reinforcement 60 so that the foam part 32 in the filling structure 30 can absorb the force on the metal reinforcement 60. On the other hand, it can prevent the lower end of the filling reinforcement from being too long, which not only avoids wasting the production materials of the filling structure 30, but also ensures the normal setting of the hinges and mounting holes on the metal structure.

[0044] Combination Figure 4 As shown, the frame member 31 is spaced from the B-pillar inner panel 20 and the side panel 10, and the spacing distance is D1. The thickness of the foam member 32 before foaming and expansion is D2. D1 and D2 satisfy the relationship: D1≥3mm, 2mm≤D2≤4mm. Specifically, the spacing distance between the frame member 31 and the B-pillar inner panel 20 is set to be not less than 3mm, and the thickness of the foam member 32 before foaming and expansion is set to be between 2mm and 4mm. In this way, when the frame member 31 is set between the B-pillar inner panel 20 and the side panel 10, the foam member 32 can be spaced from the B-pillar inner panel 20 to facilitate the assembly of the body side panel 100. If the spacing distance between the frame member 31 and the B-pillar inner panel 20 is set to be less than 3mm, it is easy to cause the spacing distance between the B-pillar inner panel 20 and the frame member 31 to be too small, which will not only make it difficult to assemble the filling structure 30 in the body side panel 100, but also reduce the vibration isolation and noise reduction ability of the body side panel 100. Likewise, the spacing between the frame member 31 and the side panel 10 is not less than 3 mm.

[0045] Furthermore, the thickness of the foaming member 32 in the embodiment of the utility model before foaming is between 2mm and 4mm. If the thickness of the foaming member 32 before foaming and expansion is less than 2mm, the structure of the foaming member 32 is too thin, so that after foaming and expansion, it is impossible to ensure that the foaming member 32 is fully bonded to the sheet metal structures such as the B-pillar inner panel 20, the side panel 10 and the metal reinforcement 60, which will affect the energy absorption effect of the filling structure 30 during collision. In addition, if the thickness of the foaming member 32 before foaming and expansion is more than 4mm, the structure of the foaming member 32 is too thick, which may cause the foaming member 32 to overflow and block the hole, which is easy to affect the assembly of other parts.

[0046] Furthermore, in the embodiment of the utility model, the distance between the foaming part 32 and the B-pillar inner panel 20 and the side panel 10 before foaming and expansion is set to D6, and the value of D6 includes but is not limited to 2.8 mm, 2.9 mm, 3.0 mm, 3.1 mm and 3.2 mm. In this way, the reliability of the adhesion between the foaming part 32 and the B-pillar inner panel 20 and the side panel 10 after foaming and expansion can be ensured, so as to ensure the effectiveness of the filling structural part 30 in improving the rigidity and strength of the vehicle body side panel 100.

[0047] According to the embodiment of the utility model, the foaming ratio of the foaming member 32 is Q, and Q satisfies the relationship: 150%≤Q≤350%. Specifically, by baking the foaming member 32 at a set baking temperature and baking time, the foaming ratio of the foaming member 32 can be between 150% and 350%, so that the foaming member 32 can be suitable for different vehicle models and different rigidity and strength requirements of the body side 100.

[0048] Combination Figure 4 As shown, the thickness of the frame member 31 is D3, and D3 satisfies the relationship: 2mm≤D3≤4mm. Specifically, when the frame member 31 is arranged between the B-pillar inner panel 20 and the side panel 10, it mainly provides support for the foam member 32. Therefore, the frame member 31 needs to have a certain rigidity and strength to ensure the structural reliability of the foam member 32 between the B-pillar inner panel 20 and the side panel 10. If the thickness of the frame member 31 is set to be less than 2mm, the structure of the frame member 31 is thin, and the rigidity and strength of the structure are weak, and the structural requirements of the vehicle body side panel 100 cannot be met. If the thickness of the frame member 31 is set to exceed 4mm, the weight of the frame member 31 increases, which is not conducive to the lightweighting of the entire vehicle. In this way, setting the thickness of the frame member 31 between 2mm and 4mm can not only ensure the structural reliability of the frame member 31, but also help to achieve lightweighting of the entire vehicle. In the embodiment of the present utility model, the material of the frame member 31 includes but is not limited to at least one of nylon and glass fiber, and the thickness of the frame member 31 can be determined according to the safety performance requirements of the whole vehicle and the baking simulation analysis results.

[0049] Combination Figure 3 As shown, a positioning hole 311 is provided on the frame member 31, and the positioning hole 311 is used for positioning and cooperating with the B-pillar inner panel 20 and the side panel 10. In this way, when the filling structure 30 is installed between the B-pillar inner panel 20 and the side panel 10, the frame member 31 can be accurately positioned between the B-pillar inner panel 20 and the side panel 10 through the positioning hole 311 to ensure the accuracy of the installation position of the filling structure 30, thereby improving the assembly convenience of the vehicle body side panel 100.

[0050] Combination Figure 3As shown, the positioning holes 311 include a main positioning hole 3111 and a secondary positioning hole 3112. The main positioning hole 3111 and the secondary positioning hole 3112 are arranged at intervals in the length direction of the frame member 31. The length of the frame member 31 is L1. The center distance between the main positioning hole 3111 and the secondary positioning hole 3112 is L2. L1 and L2 satisfy the relationship: L2 ≥ 2 / 3L1. Specifically, the center distance between the main positioning hole 3111 and the secondary positioning hole 3112 on the frame member 31 is set to be at least 2 / 3 of the overall length of the frame member 31. In this way, not only can the frame member 31 be quickly and accurately positioned with the B-pillar inner panel 20 and the side panel 10, but also the positioning reliability of the frame member 31 between the B-pillar inner panel 20 and the side panel 10 can be ensured, which is conducive to improving the installation accuracy of the frame member 31 between the B-pillar inner panel 20 and the side panel 10.

[0051] Combination Figure 3 As shown, the skeleton member 31 is provided with a leakage hole 312, and there are multiple leakage holes 312, and the multiple leakage holes 312 are arranged at intervals on the skeleton member 31. Specifically, the leakage holes 312 on the skeleton member 31 can not only avoid electrophoretic liquid accumulation during the vehicle production process, but also facilitate the flow of hot air when baking the foaming member 32. The multiple leakage holes 312 are arranged on the skeleton member 31, which can improve the leakage efficiency and gas flow efficiency, and thus ensure the safety during vehicle production. The multiple leakage holes 312 are arranged at intervals on the skeleton member 31, which can reduce the stress concentration on the skeleton member 31, which is conducive to ensuring the structural strength of the skeleton member 31.

[0052] Combination Figure 3 As shown, the leakage hole 312 includes but is not limited to a circular hole and a square hole. The diameter of the circular hole is set to D4, and D4 satisfies the relationship: 3mm≤D4≤5mm. If the diameter of the circular hole is set to be less than 3mm, the flow efficiency of the electrophoretic effluent or the hot air flow through the leakage hole 312 is low, and the safety during electrophoresis and baking cannot be guaranteed. If the diameter of the circular hole is set to exceed 5mm, the diameter of the leakage hole 312 is too large, which will affect the structural strength of the frame member 31. The side length of the square hole is set to D5, and D5 includes but is not limited to 4.8mm, 4.9mm, 5.0mm, 5.1mm and 5.2mm, which can ensure the leakage and gas leakage rates of the leakage hole 312.

[0053] Combination Figure 3As shown, the frame member 31 is provided with a welding portion 313, and the welding portion 313 is welded and fixed to the B-pillar inner plate 20 and the side panel 10. Specifically, the frame member 31 is connected to the B-pillar inner plate 20 and the side panel 10 by the welding portion 313. On the one hand, the installation method of the frame member 31, the B-pillar inner plate 20 and the side panel 10 can be simplified, which is conducive to improving the assembly efficiency of the filling structure 30 between the B-pillar inner plate 20 and the side panel 10. On the other hand, the connection strength of the frame member 31, the B-pillar inner plate 20 and the side panel 10 can be ensured, and the setting reliability of the filling structure 30 between the B-pillar inner plate 20 and the side panel 10 can be ensured, and the filling structure 30 can be effectively prevented from falling off during transportation. In addition, compared with the manual offline buckle installation method in the prior art, the use of a welding fixture to weld and assemble the frame member 31, the B-pillar inner plate 20 and the side panel 10 can make the matching accuracy of the parts higher, prevent wrong installation and missing installation, and help improve production efficiency.

[0054] In the embodiment of the present invention, the welding portion 313 includes but is not limited to a cold-rolled steel plate, and the thickness of the welding portion 313 includes but is not limited to 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm and 0.8 mm.

[0055] According to an embodiment of the utility model, at least one of the side panel 10 and the B-pillar inner panel 20 is provided with a mounting hole, and the foaming member 32 is spaced from the mounting hole. Specifically, when the foaming member 32 is used to bond the B-pillar inner panel 20 and the side panel 10, it is necessary to ensure that the foaming member 32 is arranged away from the mounting holes on the B-pillar inner panel 20 and the side panel 10, so as to prevent the foaming member 32 from blocking the mounting holes on the B-pillar inner panel 20 and the side panel 10 after foaming and expansion, and ensure the normal connection between the B-pillar inner panel 20 and the side panel 10. In an embodiment of the utility model, when the foaming rate of the foaming member 32 is between 150% and 350%, the distance between the mounting hole and the foaming member 32 in the foaming direction of the foaming member 32 is at least 15 mm.

[0056] Combination Figure 4 As shown, the frame member 31 is provided with grooves 3113, and there are multiple grooves 3113, and the multiple grooves 3113 are arranged at intervals on the frame member 31, and the foamed and expanded foamed member 32 is filled in the multiple grooves 3113. Specifically, the grooves 3113 on the frame member 31 can provide a stable and reliable setting position for the foamed member 32. In this way, when the foam glue is set on the frame member 31, it is not only convenient to find the position of the foamed member 32, which is conducive to improving the convenience of setting the foamed member 32, but also it can ensure that when the filling structural member 30 before foaming is set between the B-pillar inner panel 20 and the side panel 10, a suitable interval is maintained between the B-pillar inner panel 20 and the side panel 10, so that the assembly of the B-pillar inner panel 20 and the side panel 10 before foaming can be facilitated.

[0057] According to the embodiment of the utility model, the vehicle body side panel 100 can be applied to a vehicle. In the embodiment of the utility model, the filling structure 30 includes but is not limited to being applied between the upper section of the B-pillar inner panel 20 and the side panel 10, which can not only meet the collision performance requirements of the vehicle such as side collision and top pressure, but also help to improve the NVH performance of the vehicle. Furthermore, the parts of the B-pillar inner panel 20 can be reduced, which is conducive to saving development costs.

[0058] Filling structural members 30 can be provided between the B-pillar inner panel 20 and the side panel 10 of the body side panel 100, between the A-pillar 40 inner panel and the side panel 10, and between the door sill beam 50 and the side panel 10. After welding, the body side panel 100 is baked to allow the foaming member 32 in the body side panel 100 to foam and expand. The foaming rate of the foaming member 32 can be adjusted by adjusting the baking time and the baking temperature, and then the thickness of the foaming member 32 after foaming and expansion can be adjusted, so that the bonding reliability of the foaming member 32 with the A-pillar 40 inner panel, the B-pillar inner panel 20, the door sill beam 50 and the side panel 10 can be ensured. With such a configuration, the rigidity and strength of the body side panel 100 can be improved, and the damage to the occupants in the vehicle during a vehicle collision can be effectively reduced.
