Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a wind vane, a front bumper assembly, and a vehicle. Background Technology

[0002] When a vehicle is traveling at high speed, wind generates drag in the direction of the vehicle's movement and lift in the direction of gravity, thus affecting the vehicle's range and driving stability. In related technologies, manufacturers have installed air blades on the front bumper to reduce air resistance. However, the design of these air blade structures is often flawed, leading to noise generation during driving and negatively impacting the vehicle's overall aerodynamic performance. Utility Model Content

[0008] According to an embodiment of the present invention, the air knife, with its first and second fixing parts arranged at intervals along the vertical direction on the extension section and used for connection to the vehicle body, provides auxiliary support to the extension section after the air knife is assembled onto the vehicle body. This reduces the swaying amplitude of the extension section during vehicle operation, improves the modal performance of the air knife, and helps reduce noise during vehicle operation. Furthermore, since the extension section of the air knife extends vertically, it can streamline the airflow at the front of the vehicle, thereby reducing wind resistance during vehicle operation.

[0016] In some embodiments, at least one of the first fixing part and the second fixing part includes a column, one end of which is connected to the extension section, and the other end of which is used to connect to the vehicle body.

[0017] In some embodiments, the air knife is provided with a plurality of buckles, some of which are provided on the main body section and are spaced apart along the left and right directions of the main body section, while other of the buckles are provided on the lower edge of the extension section.

[0019] According to the front bumper assembly of this utility model, since the first fixing part and the second fixing part are arranged at intervals along the vertical direction on the extension section, and the first fixing part and the second fixing part are used to connect with the vehicle body, when the air blade is assembled onto the vehicle body, the first fixing part and the second fixing part can provide auxiliary support for the extension section, thereby reducing the sway amplitude of the extension section during vehicle operation, improving the modal performance of the air blade, and helping to reduce noise during vehicle operation. In addition, since the extension section of the air blade extends along the vertical direction, it can sort the airflow at the front of the vehicle, thereby reducing wind resistance during vehicle operation. Therefore, the front bumper assembly of this utility model can reduce vibration noise during vehicle operation and optimize the aerodynamic performance of the entire vehicle.

[0039] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following is a reference appendix. Figures 1 to 7 This invention describes an embodiment of the air blade 100, a front bumper assembly, and a vehicle.

[0041] like Figures 1 to 4 As shown, the air knife 100 of this utility model embodiment includes: a main body section 101 and an extension section 102, the extension section 102 being disposed in the left-right direction of the main body section 101 (e.g., Figure 1 The extension section 102 extends along one side of the main body section 101 (in the length direction) and along the vertical direction of the main body section 101. The extension section 102 includes a first fixing part 1021 and a second fixing part 1022 for connection with the vehicle body. The first fixing part 1021 and the second fixing part 1022 are arranged at intervals along the vertical direction on the extension section 102.

[0042] It is understandable that the up, down, left, right, front, and back of the wind blade 100 is consistent with the up, down, left, right, front, and back of the vehicle.

[0043] According to an embodiment of the present invention, the air blade 100, with its first fixing part 1021 and second fixing part 1022 arranged at intervals along the vertical direction on the extension section 102, and the first fixing part 1021 and second fixing part 1022 used for connection with the vehicle body, provides auxiliary support to the extension section 102 after the air blade 100 is assembled onto the vehicle body. This reduces the swaying amplitude of the extension section 102 during vehicle operation, improves the modal performance of the air blade 100, helps reduce noise during vehicle operation, and enhances vehicle stability. Since the extension section 102 of the air blade 100 extends vertically, it can streamline the airflow at the front of the vehicle, thereby reducing wind resistance during vehicle operation. Therefore, the air blade 100 of this embodiment can reduce vibration noise during vehicle operation and optimize the aerodynamic performance of the entire vehicle.

[0044] It should be noted that there can be one or more first fixing parts 1021 and second fixing parts 1022.

[0045] For example, when the length of the extension segment 102 in the vertical direction is large, the number of the first fixing part 1021 or the second fixing part 1022 can be increased accordingly. When the length of the extension segment 102 in the vertical direction is small, the number of the first fixing part 1021 or the second fixing part 1022 can be reduced accordingly. This utility model does not limit this.

[0046] The extension section 102 of this utility model has two fixing points: a first fixing part 1021 and a second fixing part 1022. Compared with the "suspended extension section 102" solution, this enhances the structural strength of the extension section 102 and improves its resistance to deformation. When the vehicle scrapes or collides with an obstacle, the extension section 102 can effectively protect the vehicle. Furthermore, when the user manually presses or bends the extension section 102 of the air blade 100, the deformation of the extension section 102 is relatively small, which helps to improve the overall quality of the vehicle and enhance the user experience.

[0047] It is understandable that, such as Figure 5 As shown, the main body section 101 is generally located on the front side of the front bumper 200 of the vehicle body, and the extension section 102 is generally located on the left or right side of the front bumper 200. The extension section 102 of the air blade 100 can sort the airflow at the front of the vehicle, so that some of the airflow blows across the tires in a front-to-rear direction, thereby reducing the temperature of the tires during driving and improving the safety of vehicle driving.

[0048] like Figure 5 As shown, the inner wall of the extension section 102 is spaced apart from the outer wall of the front bumper 200 to form a guide channel 205. Thus, the airflow at the front of the vehicle can pass through the guide channel 205 and be guided to the tire position of the vehicle. On the one hand, this can reduce the resistance during vehicle driving, and on the other hand, it can lower the temperature of the tires and improve the safety of vehicle driving.

[0049] Optionally, such as Figures 2 to 4 As shown, the first fixing part 1021 is located above the second fixing part 1022. The first fixing part 1021 is spaced apart from the upper end of the extension section 102, and the second fixing part 1022 is spaced apart from the lower end of the extension section 102. It can be understood that the first fixing part 1021 and the upper edge of the extension section 102 have a certain distance, and the second fixing part 1022 and the lower edge of the extension section 102 have a certain distance. This reduces the adverse effects on airflow caused by the arrangement of the first fixing part 1021 and the second fixing part 1022. Furthermore, because the first fixing part 1021 and the upper edge of the extension section 102 have a certain distance, the extension section 102 of the air blade 100 can appear to be suspended in mid-air, improving the aesthetics of the air blade 100 after assembly with the front bumper 200.

[0050] like Figure 4 As shown, the vertical spacing of the extension segment 102 is A, and the spacing between the first fixing part 1021 and the upper edge of the extension segment 102 is B1, wherein 0.3 ≤ B1 / A ≤ 0.5. For example, B1 / A can be 0.3, 0.35, 0.4, 0.45, or 0.5.

[0051] The distance between the first fixing part 1021 and the second fixing part 1022 is B2, where 0.25 ≤ B2 / A ≤ 0.45. For example, B2 / A can be 0.25, 0.3, 0.35, 0.4, or 0.45.

[0052] The distance between the second fixing part 1022 and the lower edge of the extension section 102 is B3, where 0.15 ≤ B3 / A ≤ 0.35. For example, B3 / A can be 0.15, 0.2, 0.25, 0.3, or 0.35.

[0053] Through experimental research, the inventors of this utility model discovered that when B1, B2, B3 and A are designed according to the above parameters, the wind resistance during vehicle operation can be further reduced, while ensuring that the extension section 102 of the air knife 100 has a small vibration amplitude. This greatly reduces the noise caused by the vibration of the air knife 100 during vehicle operation, which is beneficial to improving the modal performance of the air knife.

[0054] In one example, B1 / A is 0.4, B2 / A is 0.35, and B3 / A is 0.25.

[0055] Optionally, such as Figures 2 to 4 As shown, the extension section 102 is provided with a third fixing part 1023 for connection with the vehicle body. The third fixing part 1023 is spaced apart from either the first fixing part 1021 or the second fixing part 1022 along the longitudinal direction of the extension section 102. It should be noted that the longitudinal direction of the extension section 102 is consistent with the longitudinal direction of the vehicle. Figure 1 As shown, the extension section 102 is a plate-like structure, and the extension section 102 extends along the front-rear direction of the vehicle. The thickness direction of the extension section 102 is roughly parallel to the left-right direction of the vehicle.

[0056] Understandably, the third fixing part 1023 can further strengthen the mounting structure of the extension section 102 to reduce the vibration amplitude of the extension section 102 during vehicle operation. On the other hand, since the third fixing part 1023 is spaced apart from either the first fixing part 1021 or the second fixing part 1022 along the front-rear direction of the extension section 102, the first fixing part 1021, the second fixing part 1022 and the third fixing part 1023 can be arranged in a generally triangular manner, which further improves the stability of the extension section 102 when mounted on the vehicle body.

[0057] For example, such as Figure 3 and Figure 4 As shown, the third fixing part 1023 includes a first locking hole 10231, which is provided on one side of the second fixing part 1022 along the front-back direction of the extension 102. For example, the first locking hole 10231 is provided on the front side of the second fixing part 1022 along the front-back direction of the extension 102.

[0058] On the one hand, the air blade 100 is engaged with the front bumper 200 of the vehicle body through the first locking hole 10231, which improves the ease of installation and removal of the air blade 100 and ensures the connection strength between the air blade 100 and the front bumper 200. On the other hand, since the first locking hole 10231 is located on one side of the second fixing part 1022 along the front-rear direction of the extension section 102, the disturbance of airflow caused by the engagement structure between the first locking hole 10231 and the front bumper 200 can be reduced. In other words, when the airflow flows through the guide channel 205, since the engagement structure between the first locking hole 10231 and the front bumper 200 is located on the front side of the second fixing part 1022, the airflow obstruction surface can be reduced, thereby reducing the flow resistance of the airflow.

[0059] For example, such as Figure 3 and Figure 4 As shown, the third fixing part 1023 also includes a first positioning hole 10232, which is provided on one side of the second fixing part 1022 along the front-rear direction of the extension 102. It can be understood that the first positioning post 207 on the front bumper 200 can be inserted into the first positioning hole 10232 to limit the installation of the air blade 100 in the Z-direction (up and down direction), thereby improving the ease of assembly of the air blade 100.

[0060] For example, the first positioning hole 10232 is provided on the front side of the second fixing part 1022 along the front-back direction of the extension 102, such as Figure 4 As shown, the first positioning hole 10232 is located between the second fixing part 1022 and the first locking hole 10231.

[0061] On the one hand, the air blade 100 is inserted into the front bumper 200 of the vehicle body through the first positioning hole 10232, which can improve the convenience of assembling and disassembling the air blade 100, while ensuring the connection strength between the air blade 100 and the front bumper 200. On the other hand, since the first positioning hole 10232 is located on one side of the second fixing part 1022 along the front-rear direction of the extension section 102, it can reduce the disturbance to the airflow and reduce the flow resistance of the airflow.

[0062] In some embodiments, such as Figure 3As shown, the extension section 102 includes an outer panel 112, an inner panel 122, and a frame 132. The main body section 101 is connected to the outer panel 112, the inner panel 122 is located inside the outer panel 112, and the frame 132 is located between the inner panel 122 and the outer panel 112. It can be understood that the extension section 102 has a three-layer structure consisting of the outer panel 112, the inner panel 122, and the frame 132. This improves the structural strength of the extension section 102, enhances its resistance to deformation, and reduces the amplitude of vibration during vehicle operation, thus reducing noise generation.

[0063] Optionally, the outer panel 112, inner panel 122, and frame 132 are all non-metallic components. For example, the outer panel 112, inner panel 122, and frame 132 can be plastic or carbon fiber components to reduce the overall weight of the vehicle.

[0064] like Figure 3 As shown, the outer panel 112 and the frame 132 can be connected by piercing welding. There can be multiple welding points on the outer panel 112 and the frame 132, which are arranged at intervals on the frame 132. The inner panel 122 and the frame 132 can be connected by adhesive bonding to ensure the overall appearance of the outer panel 112, inner panel 122 and frame 132 after assembly.

[0065] like Figure 3 As shown, the main body section 101 and the outer plate 112 are integrally formed parts. The structure of the main body section 101 can be designed according to the shape of the vehicle. This utility model does not limit the structure of the main body section 101.

[0066] For example, such as Figure 1 and Figure 2 As shown, the main body section 101 has a flange section 104 at one end away from the extension section 102. In the direction from front to back, the flange section 104 gradually extends upward at an angle. The flange section 104 is adapted to the front shovel or front bumper 200 of the vehicle.

[0067] Optionally, such as Figure 3 and Figure 4 As shown, at least one of the first fixing part 1021 and the second fixing part 1022 includes a nut 10211, which is disposed on the frame 132. The inner plate 122 has a mating hole 1221, which is arranged opposite to the nut 10211. It is understood that a threaded component passes through the front bumper 200 and is screwed into the nut 10211 to fix the air knife 100. For example, the threaded component can be a self-tapping screw.

[0068] For example, one of the first fixing part 1021 and the second fixing part 1022 is a box-shaped spring nut and the other is a U-shaped spring nut.

[0069] Optionally, such as Figure 1and Figure 2 As shown, the air knife 100 is provided with multiple clips 103. Some clips 103 are located on the main body section 101 and are arranged at intervals along the left and right directions of the main body section 101. Other clips 103 are located on the lower edge of the extension section 102. This can improve the reliability of the installation of the air knife 100 and the front bumper 200, and help reduce the number of threaded parts used, so as to facilitate the disassembly and assembly of the air knife 100.

[0070] In other embodiments, at least one of the first fixing part 1021 and the second fixing part 1022 includes a column (not shown) with one end connected to the extension section 102 and the other end connected to the vehicle body (front bumper 200). It is understood that the column is disposed on the inner wall surface of the extension section 102 and extends along the thickness direction of the extension section 102.

[0071] It is understood that one end of the column is connected to the inner wall of the extension section 102, and the other end of the column is connected to the front bumper 200, so that the inner wall surface of the extension section 102 and the outer wall surface of the front bumper 200 form a guide channel 205. The air knife 100 of this embodiment of the invention, by designing the first fixing part 1021 and the second fixing part 1022 as a column structure, facilitates the integration of the air knife 100 into any vehicle. During installation, only a hole needs to be drilled at the corresponding position on the front bumper 200, improving the flexibility of the air knife 100 installation.

[0072] like Figures 5 to 7 As shown, another embodiment of the front bumper assembly of the present invention includes: a front bumper 200 and a wind blade 100. The wind blade 100 is the wind blade 100 of the present invention. The wind blade 100 is disposed on the front bumper 200. The first fixing part 1021 and the second fixing part 1022 are both connected to the front bumper 200.

[0073] According to the front bumper assembly of this utility model, since the first fixing part 1021 and the second fixing part 1022 are arranged at intervals along the vertical direction on the extension section 102, and the first fixing part 1021 and the second fixing part 1022 are used to connect with the vehicle body, when the air blade 100 is assembled onto the vehicle body, the first fixing part 1021 and the second fixing part 1022 can provide auxiliary support for the extension section 102, thereby reducing the sway amplitude of the extension section 102 during vehicle operation, improving the modal performance of the air blade 100, and helping to reduce noise during vehicle operation. In addition, since the extension section 102 of the air blade 100 extends along the vertical direction, it can comb the airflow at the front of the vehicle, thereby reducing wind resistance during vehicle operation. Therefore, the front bumper assembly of this utility model can reduce vibration noise during vehicle operation and optimize the aerodynamic performance of the entire vehicle.

[0074] like Figure 5As shown, the inner wall of the extension section 102 is spaced apart from the outer wall of the front bumper 200 to form a guide channel 205. Thus, the airflow at the front of the vehicle can pass through the guide channel 205 and be directed to the tires, which reduces drag during vehicle operation and lowers tire temperature, thereby improving vehicle safety.

[0075] Optionally, such as Figures 5 to 6 As shown, the front bumper 200 is provided with a first support column 201 and a second support column 202. Both the first support column 201 and the second support column 202 are located within the airflow channel 205, and are connected to the first fixing part 1021 and the second fixing part 1022 in a one-to-one correspondence. It can be understood that both the first support column 201 and the second support column 202 abut against the inner panel 122, thereby allowing the inner wall surface of the extension section 102 to be separated from the outer wall surface of the front bumper 200 by the airflow channel 205. Under the abutment action of the first support column 201 and the second support column 202, the extension section 102 has stronger resistance to deformation and a more stable structure.

[0076] like Figure 7 As shown, both the first support column 201 and the second support column 202 are provided with through holes 2011, and the threaded parts pass through the through holes 2011 and are connected to the corresponding nuts 10211.

[0077] like Figure 7 As shown, at least one of the first support column 201 and the second support column 202 includes a windward portion 211. The windward portion 211 has an upper windward surface 2111 and a lower windward surface 2112. The upper windward surface 2111 and the lower windward surface 2112 are arranged in a vertical direction. The upper windward surface 2111 is located above the lower windward surface 2112. In the direction from the air outlet of the guide channel 205 to the air inlet of the guide channel 205, the distance between the upper windward surface 2111 and the lower windward surface 2112 gradually decreases.

[0078] For example, the front ends of the first support column 201 and the second support column 202 are both provided with a windward portion 211.

[0079] Understandably, the windward part 211 gradually tapers in the direction from the air outlet to the air inlet of the air guide channel 205, thereby reducing the resistance of the airflow when passing through the first support column 201 and the second support column 202, so as to further reduce wind resistance and increase vehicle speed.

[0080] In some embodiments, such as Figure 5 and Figure 6As shown, the front bumper 200 includes a bumper body 203 and a split plate 204. The split plate 204 is detachably connected to the bumper body 203, and a first support column 201 and a second support column 202 are disposed on the split plate 204. Figure 6 As shown, the split plate 204 can be the air curtain cover of the front bumper 200. Because the split plate 204 has a small structural size, it is convenient to form the first support column 201 and the second support column 202 on the split plate 204. Therefore, the front bumper assembly of this embodiment of the present invention, by designing the front bumper 200 with the above-described structure, can be easily manufactured.
