Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a side beam assembly and a vehicle. Background Technology

[0002] To meet the demands for lightweight vehicle bodies and improved safety, hot-expansion tube beams are increasingly being used in vehicle bodies to enhance body rigidity and safety performance. In these technologies, the hot-expansion tube beam is typically covered by sheet metal, and the cavity formed between the hot-expansion tube beam and the external sheet metal needs to be sealed to improve the NVH (noise, vibration, and harshness) properties of the body-in-white.

[0003] However, if the cavity between the hot gas expansion tube beam and the external sheet metal parts is completely sealed, the electrophoretic solution may not be able to enter the cavity during the electrophoresis process. This can lead to the outer wall of the hot gas expansion tube beam and the inner wall of the sheet metal parts covering the hot gas expansion tube beam being unable to contact the electrophoretic solution, thus failing to guarantee the integrity and quality of the electrophoresis. Utility Model Content

[0004] In view of this, the present invention provides a side beam assembly and carrier to solve the problem that the integrity and goodness of electrophoresis cannot be guaranteed after the cavity between the hot gas expansion tube beam and the external sheet metal parts is completely sealed.

[0005] In a first aspect, this utility model provides a side beam assembly, comprising:

[0006] The outer beam covers the outside of the inner beam, forming an outer cavity between them; the inner beam is hollow to form an inner cavity.

[0007] The internal sealing assembly is located within the internal cavity.

[0008] The external sealing assembly is located within the external cavity;

[0009] The inner sealing assembly and the outer sealing assembly have an original state before volume expansion and an expanded state after volume expansion; in the original state, the outer sealing assembly has at least a portion of a through-hole formed, which is adapted to conduct the outer cavity located on both sides of the outer sealing assembly; in the expanded state, the inner sealing assembly is adapted to seal at least one end of the inner cavity, and the outer sealing assembly is adapted to seal at least one end of the outer cavity.

[0010] Beneficial effects: Wind noise generated by high-speed vehicle travel can easily cause hollow noise in the inner and outer cavities. When the inner and outer sealing assemblies are in an expanded state, they can seal the inner and outer cavities, effectively reducing and isolating the hollow noise caused by wind noise at high speeds, thus improving the NVH performance and safety of the body-in-white. Furthermore, since the inner walls of the outer and inner beams need to be treated with electrophoresis to improve corrosion resistance, the complete seal formed after the expansion of the inner and outer sealing assemblies can prevent the electrophoresis solution from entering the cavities during the electrophoresis process. This can lead to a situation where the inner walls of the outer and inner beams cannot contact the electrophoresis solution, compromising the integrity and effectiveness of the electrophoresis process. Therefore, by forming a liquid passage through at least a portion of the outer sealing assembly, the liquid passage can connect the outer cavity to both sides of the outer sealing assembly in the original state before volume expansion, so that the electrophoretic liquid can enter the interior of the outer cavity, thereby ensuring the integrity and good performance of electrophoresis.

[0011] In one optional embodiment, the outer sealing assembly includes an outer skeleton and an outer adhesive layer. The outer skeleton is fitted around the outer periphery of the inner beam and is adapted to fix the outer adhesive layer at a predetermined position on the outer periphery of the inner beam.

[0012] Beneficial effects: The outer frame is fitted around the outer periphery of the inner beam, which makes it easy to fix the outer adhesive layer to the preset position on the outer periphery of the inner beam.

[0013] In one alternative embodiment, the outer sealing assembly further includes a first snap fastener, and the inner beam has a first mounting hole through it, the first snap fastener being adapted to fix the outer frame to the first mounting hole.

[0014] In one alternative embodiment, the inner sealing assembly includes: an inner skeleton and an inner adhesive layer, wherein the inner skeleton is at least partially disposed within the inner cavity;

[0015] Along the extension direction of the inner cavity, the inner adhesive layer is disposed on at least one side of the inner skeleton, and the inner skeleton is adapted to support the inner adhesive layer.

[0016] Beneficial effects: By placing the inner rubber layer inside the inner cavity, the inner cavity can be sealed more effectively after expansion, effectively reducing and isolating the air noise generated by wind noise during high-speed driving, thus improving NVH performance.

[0017] In one alternative embodiment, the inner sealing assembly further includes a second snap-fit, with a second mounting hole formed through the inner beam, the second snap-fit ​​being adapted to secure the inner frame to the second mounting hole.

[0018] In one alternative implementation, the inner skeleton includes:

[0019] The skeleton body is housed within the internal cavity;

[0020] The frame fitting part is formed by a partial extension of the frame body;

[0021] The inner beam has a through-hole for locking, and the frame locking part is suitable for inserting into the locking hole to limit the inner frame.

[0022] Beneficial effects: By setting the matching of the skeleton snap-fit ​​part and the snap-fit ​​hole, the inner skeleton can be easily positioned and installed into the inner cavity.

[0023] In one alternative embodiment, the inner frame further includes: a snap-fit ​​mounting portion formed on the frame body, wherein a second snap-fit ​​is disposed on the snap-fit ​​mounting portion to fix the inner frame to the second mounting hole.

[0024] In one alternative embodiment, the inner adhesive layer comprises:

[0025] The adhesive layer body is disposed within the inner cavity;

[0026] The adhesive layer snap-fit ​​part is formed by a partial extension of the adhesive layer body, and the adhesive layer snap-fit ​​part is suitable for inserting into the snap-fit ​​hole.

[0027] Beneficial effects: When the skeleton snap-fit ​​part is inserted into the snap-fit ​​hole, there may be assembly gaps. By forming a snap-fit ​​part with the inner rubber layer, the snap-fit ​​part can be inserted into the snap-fit ​​hole. After the inner rubber layer foams and expands, the snap-fit ​​part can completely fill the snap-fit ​​hole, thereby improving the sealing effect and enhancing NVH performance.

[0028] In one alternative embodiment, the outer adhesive layer comprises an integral ring structure.

[0029] Beneficial effects: The outer rubber layer adopts an integrated ring structure. Supported by the outer skeleton, the stability of this integrated ring structure is ensured, allowing for more effective sealing of the sheet metal cavity after expansion, thus enhancing the NVH (noise, vibration, and harshness) properties and safety performance of the body-in-white. Compared to using multiple separate outer rubber blocks, this reduces assembly difficulty and effectively ensures the integrity of the foam after foaming. It also effectively reduces and isolates the air noise generated by wind noise at high speeds, which can cause hollow noise in the outer cavity, thereby improving NVH performance.

[0030] Secondly, the present invention also provides a vehicle, including: a vehicle body, and a side beam assembly as described above disposed on the vehicle body.

[0031] In one optional embodiment, the vehicle includes a vehicle with A-pillars, B-pillars, and C-pillars arranged sequentially along the vehicle length direction. The inner beam is a tubular beam that extends from the region of the A-pillar away from the B-pillar along the vehicle length direction to the upper region of the B-pillar along the vehicle height direction. An inner sealing assembly and an outer sealing assembly are disposed in the region of the A-pillar away from the B-pillar along the vehicle length direction, and / or in the upper region of the B-pillar along the vehicle height direction.

[0032] In one optional embodiment, the vehicle includes a vehicle with A-pillars, B-pillars, and C-pillars arranged sequentially along the vehicle length direction. The inner beam is a tubular beam that extends from the region of the A-pillar away from the B-pillar along the vehicle length direction to the upper region of the C-pillar along the vehicle height direction. An inner sealing assembly and an outer sealing assembly are disposed in the region of the A-pillar away from the B-pillar along the vehicle length direction, and / or in the upper region of the C-pillar along the vehicle height direction.

[0053] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0054] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0055] According to an embodiment of the present invention, in one aspect, a side beam assembly is provided, comprising:

[0056] Outer beam 1 and inner beam 2, with outer beam 1 covering the outside of inner beam 2, forming an outer cavity 100 between outer beam 1 and inner beam 2; inner beam 2 is hollow inside to form an inner cavity 200;

[0057] The inner sealing assembly 4 is located within the inner cavity 200;

[0058] The outer sealing assembly 3 is disposed within the outer cavity 100;

[0059] The inner sealing assembly 4 and the outer sealing assembly 3 have an original state before volume expansion and an expanded state after volume expansion; in the original state, the outer sealing assembly 3 has at least a partially open area forming a liquid passage 31, which is adapted to connect the outer cavity 100 located on both sides of the outer sealing assembly 3; in the expanded state, the inner sealing assembly 4 is adapted to seal at least one end of the inner cavity 200, and the outer sealing assembly 3 is adapted to seal at least one end of the outer cavity 100.

[0060] In some embodiments, combined with Figure 2 As shown, the outer beam 1 includes a first outer beam plate 11 and a second outer beam plate 12, which together enclose the outer beam 1. In this embodiment, there is no contact between the outer beam 1 and the inner beam 2.

[0061] The inner sealing assembly 4 and the outer sealing assembly 3 have an original state before volume expansion and an expanded state after volume expansion. To facilitate understanding of the effects of the original state and the expanded state respectively, the technical contents related to the original state and the expanded state are described separately below.

[0062] First, regarding the expansion state after volume expansion.

[0063] Because wind noise generated by the vehicle at high speed can easily cause hollow noise in the inner cavity 200 and the outer cavity 100, sealing the inner cavity 200 and the outer cavity 100 can effectively reduce the occurrence of hollow noise.

[0064] In this embodiment, the inner sealing assembly 4 and the outer sealing assembly 3 may specifically include EVA foam material, which has good expansion properties when heated. Through experiments, heating the inner sealing assembly 4 can completely seal the inner cavity 200, and similarly, heating the outer sealing assembly 3 can completely seal the outer cavity 100. This effectively reduces and isolates the air noise generated by wind noise from high-speed driving, which causes humming noise in the inner cavity 200 and outer cavity 100, thus improving the NVH performance of the body-in-white.

[0065] By setting an inner sealing assembly 4 in the inner cavity 200, the inner cavity 200 can be better sealed after high-temperature foaming. Similarly, by setting an outer sealing assembly 3 in the outer cavity 100, the outer cavity 100 can be better sealed after high-temperature foaming, thereby providing better NVH performance and vehicle body safety performance.

[0066] Secondly, regarding the original state before volume expansion.

[0067] Since the inner walls of the outer beam 1 and inner beam 2 need to be treated with electrophoretic fluid to improve corrosion resistance, after the inner sealing assembly 4 and outer sealing assembly 3 expand in volume, the inner cavity 200 and outer cavity 100 form a complete seal. This can easily lead to the electrophoretic fluid being unable to enter the cavity during the electrophoresis process, resulting in the inner walls of the outer beam 1 and inner beam 2 being unable to contact the electrophoretic fluid, thus failing to guarantee the integrity and quality of the electrophoresis. Therefore, in this embodiment, a liquid passage hole 31 is formed through at least a portion of the outer sealing assembly 3. In the original state before the volume expansion, the liquid passage hole 31 can connect the outer cavity 100 to both sides of the outer sealing assembly 3, allowing the electrophoretic fluid to enter the interior of the outer cavity 100, thereby ensuring the integrity and quality of the electrophoresis, enhancing corrosion resistance, and effectively guaranteeing the vehicle body safety performance.

[0068] The specific production process of the side beam assembly in this embodiment can be carried out as follows: after assembly, it is first electrophoretic in the paint shop at room temperature, and then sent to the drying oven for high-temperature baking.

[0069] Electrophoresis is performed in the paint shop at room temperature. At this time, both the inner sealing group 4 and the outer sealing group 3 are in their original state before volume expansion, which facilitates the entry of the electrophoretic liquid into the interior of the outer cavity 100, thereby ensuring the integrity and good performance of the electrophoresis.

[0070] After being placed in a drying oven for high-temperature baking, the inner sealing assembly 4 and the outer sealing assembly 3 will expand due to heat, maintaining them in an expanded state. For example, the heating temperature can be 140℃~200℃, and the heating time can be 10min~30min.

[0071] As an optional implementation, at least a portion of the inner sealing assembly 4 can also be made through to form liquid passage holes, so that the electrophoretic liquid can flow into the inner cavity 200 formed inside the inner beam 2, thereby ensuring the integrity and good performance of the electrophoresis on the inner wall of the inner beam 2.

[0072] In some embodiments, combined with Figure 4 As shown, the outer sealing assembly 3 includes an outer frame 32 and an outer adhesive layer 34. The outer frame 32 is sleeved on the outer periphery of the inner beam 2, and the outer frame 32 is adapted to fix the outer adhesive layer 34 to a preset position on the outer periphery of the inner beam 2.

[0073] The outer adhesive layer 34 can be made of EVA foam material.

[0074] The outer frame 32 is fitted around the outer periphery of the inner beam 2, which can easily fix the outer adhesive layer 34 to a preset position on the outer periphery of the inner beam 2.

[0075] In this embodiment, the outer adhesive layer 34 can be annular, and the outer skeleton 32 is inserted inside the outer adhesive layer 34 so as to fix the outer adhesive layer 34 to the inner beam 2.

[0076] Optionally, in this embodiment, the outer adhesive layer 34 adopts an integrated annular structure. Supported by the outer frame 32, the stability of the integrated annular structure is ensured, allowing for more effective sealing of the sheet metal cavity after expansion, thus enhancing the NVH performance and safety of the body-in-white. Compared to using multiple separate outer adhesive blocks, this reduces assembly difficulty and effectively ensures the integrity of the foamed structure, effectively reducing and isolating the air noise generated by wind noise during high-speed driving that causes humming noise in the outer cavity 100, thereby improving NVH performance.

[0077] In some embodiments, combined with Figure 4 , Figure 6 , Figure 7 , Figure 9 As shown, the outer sealing assembly 3 also includes a first buckle 33, and the inner beam 2 has a first mounting hole 21 through it. The first buckle 33 is suitable for fixing the outer frame 32 to the first mounting hole 21.

[0078] In one implementation, the outer frame 32 is also provided with an outer frame buckle mounting hole suitable for the first buckle 33 to pass through. After the outer sealing assembly 3 is sleeved on the inner beam 2 and the outer frame buckle mounting hole is aligned with the first mounting hole 21, the first buckle 33 is simultaneously inserted into the outer frame buckle mounting hole and the first mounting hole 21, thereby fixing the outer frame 32 to the inner beam 2.

[0079] As another implementation, the outer frame 32 can be integrated with the first buckle 33. After the outer sealing assembly 3 is fitted onto the inner beam 2 and the first buckle 33 is aligned with the first mounting hole 21, the first buckle 33 is engaged into the first mounting hole 21, thereby fixing the outer frame 32 to the inner beam 2.

[0080] In this embodiment, the first buckle 33 is inserted from one side of the outer frame 32 toward the side of the inner beam 2.

[0081] In this embodiment, the outer periphery of the outer adhesive layer 34 matches the cross-sectional shape of the outer cavity 100, thereby ensuring the fit and improving the sealing effect.

[0082] In some embodiments, combined with Figure 6 As shown, the inner sealing assembly 4 includes: an inner skeleton 41 and an inner adhesive layer 42, wherein the inner skeleton 41 is at least partially disposed within the inner cavity 200;

[0083] Along the extending direction of the inner cavity 200, the inner adhesive layer 42 is disposed on at least one side of the inner skeleton 41, and the inner skeleton 41 is adapted to support the inner adhesive layer 42.

[0084] The inner adhesive layer 42 can be made of EVA foam material.

[0085] In this embodiment, the inner skeleton 41 is constructed as a sheet. By placing the inner skeleton 41 into the inner cavity 200, the inner sealing assembly 4 can easily seal the inner cavity 200.

[0086] In this embodiment, the outer periphery of the inner skeleton 41 matches the cross-sectional shape of the inner cavity 200, thereby ensuring a good fit and improving the sealing effect.

[0087] Along the extending direction of the inner cavity 200, the inner rubber layer 42 is disposed on one side of the inner frame 41, or the inner rubber layer 42 can be disposed on both sides of the inner frame 41. By disposing of the inner rubber layer 42 within the inner cavity 200, the inner cavity 200 can be more effectively sealed after expansion, effectively reducing and isolating the air noise generated by wind noise from high-speed vehicle travel that causes the inner cavity 200 to generate humming noise, thereby improving NVH performance.

[0088] In some embodiments, the inner sealing assembly 4 further includes a second snap fastener 43, and the inner beam 2 has a second mounting hole 22 formed through it. The second snap fastener 43 is adapted to fix the inner frame 41 to the second mounting hole 22.

[0089] In some embodiments, the inner frame 41 further includes a snap-fit ​​mounting portion 413 formed on the frame body 411, and a second snap-fit ​​43 passing through the snap-fit ​​mounting portion 413 to fix the inner frame 41 to the second mounting hole 22.

[0090] In this embodiment, the first buckle 33 is inserted from one side of the inner beam 2 toward the side of the inner frame 41.

[0091] In some embodiments, the inner skeleton 41 includes:

[0092] The skeleton body 411 is set inside the inner cavity 200;

[0093] The skeleton snap-fit ​​part 412 is formed by a partial extension of the skeleton body 411;

[0094] The inner beam 2 has a through-hole 23, and the frame locking part 412 is adapted to be inserted into the locking hole 23 to limit the inner frame 41.

[0095] By setting the skeleton snap-fit ​​part 412 and the snap-fit ​​hole 23 to cooperate, the inner skeleton 41 can be easily positioned and installed into the inner cavity 200.

[0096] Similarly, in some embodiments, the inner adhesive layer 42 includes:

[0097] The adhesive layer body 421 is disposed within the inner cavity 200;

[0098] The adhesive layer snap-fit ​​portion 422 is formed by a partial extension of the adhesive layer body 421, and the adhesive layer snap-fit ​​portion 422 is suitable for inserting into the snap-fit ​​hole 23.

[0099] In this embodiment, the inner skeleton 41 matches the shape of the inner adhesive layer 42.

[0100] Since there may be assembly gaps when the skeleton snap-fit ​​part 412 is inserted into the snap-fit ​​hole 23, by forming an adhesive snap-fit ​​part 422 in the inner adhesive layer 42, the adhesive snap-fit ​​part 422 is inserted into the snap-fit ​​hole 23. After the inner adhesive layer 42 foams and expands, the adhesive snap-fit ​​part 422 can completely fill the snap-fit ​​hole 23, thereby improving the sealing effect and enhancing NVH performance.

[0101] The side beam assembly provided in the embodiment of this utility model adopts a hollow outer beam 1 and inner beam 2, which is a lightweight structure and is lighter than other reinforcement structures. The inner sealing group 4 and the outer sealing group 3 are fixed to the inner beam 2 by snap-fit. The structure is modular and standardized, which is convenient for widespread application.

[0102] According to an embodiment of the present invention, another aspect provides a vehicle, including: a vehicle body, and a side beam assembly as described above disposed on the vehicle body.

[0103] In this embodiment, the vehicle includes an A-pillar 300, a B-pillar 400, and a C-pillar 500, which are arranged sequentially along the length of the vehicle. Specifically, the A-pillar 300 refers to the pillars on both sides of the vehicle's windshield, the B-pillar 400 refers to the pillar between the front and rear doors, and the C-pillar 500 refers to the pillars on both sides of the rear windshield. Alternatively, the C-pillar 500 may also refer to the pillar between the vehicle's triangular window and the rear door.

[0104] The vehicle length direction refers to the front-to-back direction of the vehicle.

[0105] In some embodiments, the inner beam 2 is a tubular beam that extends from the region of the A-pillar 300 away from the end of the B-pillar 400 along the vehicle length direction to the upper region of the B-pillar 400 along the vehicle height direction; the inner sealing assembly 4 and the outer sealing assembly 3 are disposed in the region of the A-pillar 300 away from the end of the B-pillar 400 along the vehicle length direction, and / or, are disposed in the upper region of the B-pillar 400 along the vehicle height direction.

[0106] In some other embodiments, the inner beam 2 is a tubular beam that extends from the region of the A-pillar 300 away from the B-pillar 400 along the length of the vehicle to the upper region of the C-pillar 500 along the height of the vehicle; the inner sealing group 4 and the outer sealing group 3 are disposed in the region of the A-pillar 300 away from the B-pillar 400 along the length of the vehicle, and / or in the upper region of the C-pillar 500 along the height of the vehicle.

[0107] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
