[0033] The present invention provides a flow guide structure. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The flow guide structure includes a main flow guide member 1 and two side flow guide members 2; the two side flow guide members 2 are respectively installed on the opposite side surfaces of the main flow guide member 1 and are respectively connected to the main flow guide member 1; a first air vent 3 is provided on the main flow guide member 1, and a second air vent 4 is provided on the side of each side flow guide member 2 away from the main flow guide member 1.

[0034] As an example, the flow-guiding structure includes a main flow-guiding member 1 and two side flow-guiding members 2; when installed, the main flow-guiding member 1 is arranged opposite to the working member (such as the radiator 8), and a first air vent 3 is provided on the main flow-guiding member 1, which is connected to the flow-guiding cavity in the main flow-guiding member 1, and air is taken in or out through the first air vent 3 to meet the use requirements of the working member. The two side flow-guiding members 2 are respectively installed on the opposite side surfaces of the main flow-guiding member 1 and are respectively connected to the main flow-guiding member 1, so that the width of the flow-guiding structure can be increased, thereby increasing the ventilation area and meeting the thermal management requirements. A second air vent 4 is provided on the side of each side flow-guiding member 2 away from the main flow-guiding member 1, and the second air vent 4 is connected to the flow-guiding cavity in the side flow-guiding member 2, and air is taken in and out through the two second air vents 4; in this way, the flow-guiding structure can take in and out air through the first air vent 3 and the two second air vents 4, which can increase the ventilation area, increase the ventilation volume, and meet the thermal management requirements.

[0035] In one embodiment, referring to Figure 1 A mounting hole 5 is respectively provided on the two opposite side surfaces of the main air guide member 1 , and the side air guide members 2 are installed in the mounting holes 5 .

[0036] As an example, during the design, a mounting hole 5 is provided on the two opposite side surfaces of the main guide member 1, and the mounting hole 5 is connected with the guide cavity in the main guide member 1; the side guide member 2 is installed in the mounting hole 5, which facilitates the installation of the side guide member 2. At the same time, the side guide member 2 is connected with the guide cavity in the main guide member 1, which can increase the ventilation area and the ventilation volume to meet the use requirements.

[0037] In one embodiment, referring to Figure 1 The flow guide structure also includes a sealing member 6, and a sealing member 6 is provided at the connection between the flow guide member 2 on each side and the main flow guide member 1.

[0038] As an example, the guide structure further includes a seal 6. During installation, a seal 6 is provided at the connection between each side guide 2 and the main guide 1. This can enhance the sealing performance of the connection between the side guide 2 and the main guide 1 and ensure ventilation. The seal 6 is made of sponge or other materials.

[0039] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 6 The side air guide 2 includes a first shell 21 and a second shell 22 ; the first shell 21 and the second shell 22 cooperate to form a air guide cavity connected to the main air guide 1 .

[0040] As an example, the side guide 2 includes a first shell 21 and a second shell 22; when installed, the first shell 21 and the second shell 22 cooperate, specifically the first shell 21 and the second shell 22 are both U-shaped shells, and the two U-shaped shells are connected to form a guide cavity; in this way, the guide cavity is connected to the guide cavity in the main guide member 1, which can increase the ventilation area and the ventilation volume to meet the use requirements.

[0041] In one embodiment, referring to Figure 1 and Figure 2 The diameter of the end of the guide cavity close to the main guide member 1 is smaller than the diameter of the end away from the main guide member 1.

[0042] As an example, during the design, the diameter of the end of the flow guide cavity close to the main flow guide 1 is smaller than the diameter of the end away from the main flow guide 1. This arrangement can reduce the space occupied by the side flow guide 2 on the basis of increasing the width of the flow guide structure, and avoid interference with other structures. In addition, when the flow guide cavity is used for air intake, the diameter of the end of the flow guide cavity close to the main flow guide 1 is the air outlet, and the diameter of the end away from the main flow guide 1 is the air inlet. This can increase the air intake area, increase the air intake volume, and meet the thermal management requirements. When the flow guide cavity is used for air discharge, the diameter of the end of the flow guide cavity close to the main flow guide 1 is the air inlet, and the diameter of the end away from the main flow guide 1 is the air outlet. This can increase the air outlet area, increase the air outlet volume, and improve the heat dissipation effect.

[0043] In one embodiment, referring to Figure 1 and Figure 2 The side guide 2 also includes a connecting structure 23; the connecting structure 23 includes a matching block 231 and a buckle 232; the block 231 is arranged on the first shell 21, and the buckle 232 is arranged on the second shell 22; or, the block 231 is arranged on the second shell 22, and the buckle 232 is arranged on the first shell 21.

[0044] As an example, the side deflector 2 also includes a connecting structure 23, which is used to assemble the first shell 21 and the second shell 22. The connecting structure 23 includes a block 231 and a buckle 232. During installation, the block 231 is positioned on the first shell 21, and the buckle 232 is positioned on the second shell 22. The block 231 and buckle 232 match, facilitating installation and removal of the first and second shells 21, 22. In another example, the block 231 is positioned on the second shell 22, and the buckle 232 is positioned on the first shell 21, which also achieves the aforementioned function.

[0045] The present invention provides a front vehicle body assembly, referring to Figure 1-6 , including a vehicle body 7, a radiator 8 and a guide structure; the radiator 8 is installed on the vehicle body 7, the main guide member 1 is installed on the radiator 8, and the side guide member 2 is installed on the vehicle body 7.

[0046] As an example, the anti-collision beam of the front vehicle body assembly is generally installed at the front end of the vehicle body 7. Due to the line limitation of the production line, there is no tooling for installing the anti-collision beam from top to bottom, and the anti-collision beam can only be installed front to back; if the width of the guide structure along the left and right directions of the vehicle is large, the anti-collision beam will interfere with the guide structure when installed front and back and cannot be installed. Therefore, it is necessary to limit the width of the guide structure so that sufficient safety distance is reserved between the two sides of the guide structure and the front and rear installation path of the anti-collision beam. However, the width of the guide structure cannot be too small. If it is too small, the ventilation area will be reduced, which does not meet the thermal management requirements. The front vehicle assembly in this example includes a vehicle body 7, a radiator 8, and an air guide structure. The air guide structure includes a main air guide 1 and two side air guides 2. During installation, the radiator 8 is mounted on the vehicle body 7, the main air guide 1 is mounted on the radiator 8, and the side air guides 2 are mounted on the vehicle body 7. A first air vent 3 is provided on the main air guide 1, communicating with the air guide cavity within the main air guide 1. Air enters or exits through the first air vent 3, meeting the requirements of radiator 8. The two side air guides 2 are mounted on opposite sides of the main air guide 1 and are connected to the main air guide 1. This increases the width of the air guide structure, thereby increasing the ventilation area and meeting thermal management requirements. A second vent 4 is provided on the side of each side guide 2, away from the main guide 1. This second vent 4 communicates with the guide cavity within the side guide 2, allowing air to enter or exit through the two second vents 4. This allows the guide structure to take in air through the first vent 3 and the two second vents 4, increasing the intake area and the air volume flowing into the radiator 8, thus meeting thermal management requirements. Furthermore, the caliber of the guide cavity at the end closest to the main guide 1 is smaller than that at the end further away from the main guide 1. This arrangement, while increasing the Y-axis length of the guide structure, reduces the space occupied by the side guide 2. Sufficient safety distance is reserved between the two sides of the guide structure and the path along which the anti-collision beam is installed, preventing interference with the anti-collision beam.

[0047] In one embodiment, referring to Figure 2 and Figure 6 The front assembly of the vehicle body also includes a fixing member 9, and a fixing support leg 24 is provided on the side deflector 2; the fixing member 9 is passed through the fixing support leg 24 and is connected to the vehicle body 7.

[0048] As an example, the front vehicle assembly also includes a fixing member 9. During installation, a fixing foot 24 is provided on the side deflector 2. The fixing member 9 is inserted into the fixing foot 24 and connected to the vehicle body 7, facilitating a secure installation of the side deflector 2 on the vehicle body 7. The fixing member 9 is formed using bolts or self-tapping screws. Specifically, the upper portion of the side deflector 2 is bolted to the vehicle body sheet metal, while the lower portion of the side deflector 2 is connected to the calf support with self-tapping screws.

[0049] In one embodiment, referring to Figure 5 The front body assembly also includes a decorative grille 10; the decorative grille 10 is installed on the body body 7, corresponding to the guide structure; the width of the guide structure is greater than the width of the decorative grille 10.

[0050] As an example, the front vehicle body assembly also includes a decorative grille 10, which is installed on the vehicle body 7 and corresponds to the air guide structure. While serving as a decorative feature for the entire vehicle, it can also effectively protect the air guide structure. The width of the air guide structure is greater than the width of the decorative grille 10, so that after the air guide structure is installed, it can block the holes on both sides of the decorative grille 10 to prevent leakage of the structure inside the cabin. In this example, due to the limitation of the production line, the existing air guide structure cannot be lengthened on both sides. By cooperating with the main air guide 1, two newly designed side air guides 2 are formed. Without destroying the shape, the new air guide structure can be used to block the internal structure, solving the problem of internal structure leakage on both sides of the decorative grille 10. It also increases the air intake area and the air intake volume of the radiator 8, meeting the thermal management requirements and achieving the required functions at the lowest cost.

[0051] An embodiment of the utility model provides an automobile, comprising a vehicle body front assembly.

[0052] As an example, an automobile includes a front body assembly, which includes a main body 7, a radiator 8, and an air guide structure. The air guide structure includes a main air guide 1 and two side air guides 2. During installation, the radiator 8 is mounted on the main body 7, the main air guide 1 is mounted on the radiator 8, and the side air guides 2 are mounted on the main body 7. A first air vent 3 is provided on the main air guide 1, which communicates with the air guide cavity within the main air guide 1. Air enters or exits through the first air vent 3 to meet the use requirements of the radiator 8. The two side air guides 2 are respectively mounted on opposite sides of the main air guide 1 and are respectively connected to the main air guide 1. This increases the width of the air guide structure, thereby increasing the ventilation area and meeting thermal management requirements. A second vent 4 is provided on the side of each side guide 2, away from the main guide 1. This second vent 4 communicates with the guide cavity within the side guide 2, allowing air to enter or exit through the two second vents 4. This allows the guide structure to take in air through three locations: the first vent 3 and the two second vents 4. This increases the air intake area and the air volume entering the radiator 8, meeting thermal management requirements. Furthermore, the diameter of the guide cavity at the end closest to the main guide 1 is smaller than that at the end further away from the main guide 1. This arrangement, while increasing the width of the guide structure, reduces the space occupied by the side guide 2. Sufficient safety distance is reserved between the two sides of the guide structure and the path along which the anti-collision beam is installed, preventing interference with the anti-collision beam.
