[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] First, let me explain the terms used in this application:

[0043] Automotive crash beams: In the event of a collision, the crash beam initially absorbs the impact force, absorbing and dispersing the collision energy through its own structural deformation. It then transfers the force to other parts of the vehicle body, such as the longitudinal beams, to reduce damage to the main structural components. It typically consists of a main beam, an energy-absorbing box, and a mounting plate.

[0044] Radiator air deflector: Improves the backflow and sealing effect on the condenser, increases heat exchange efficiency, and enhances engine cooling.

[0045] Radiator: The heat dissipation component of the engine and air conditioning system.

[0046] Rigid connection: such as bolted connection, which prevents the two connected parts from moving relative to each other.

[0047] Flexible connections: such as engine rubber mounts, allow relative movement between two connected components. It should be noted that the flexible connections mentioned below refer to flexible connections.

[0048] As mentioned above, in order to improve the heat dissipation efficiency of vehicle engines, air deflectors are usually installed in front of the radiator to guide and seal the airflow, thereby increasing the airflow and volume to the radiator and improving heat exchange efficiency.

[0049] However, as car design continues to evolve, the front cabin space is gradually being compressed. At the same time, in order to meet the requirements of functionality, collision, safety and other aspects, more and more parts are integrated into the front cabin, which further exacerbates the occupation of the front cabin space.

[0050] In this context, the cross-sectional area of ​​the air deflector is forced to be reduced, resulting in insufficient rigidity and modal stability under various operating conditions. Furthermore, due to vehicle thermal management and aerodynamic requirements, the radiator cannot provide sufficient installation constraints for the air deflector. Simultaneously, the radiator, mounted on the subframe, experiences significant vibrations with changing road conditions, leading to substantial relative movement between the radiator and surrounding components (such as crash beams). Since the air deflector is directly mounted on the radiator, it also experiences significant relative movement with its surrounding components.

[0051] Existing air guide plates include a semi-enclosed air guide plate structure, which consists of an upper air guide plate and a lower air guide plate, respectively installed on the upper and lower parts of the radiator, and rigidly connected to the radiator. Specifically, the air guide plate and the radiator are fixed together by multiple bolts on each side, forming a rigid connection.

[0052] However, existing semi-enclosed air guide plate structures have a suspended section after installation. This suspended section is usually located in the middle of the air guide plate structure and is generally unrestrained. It should be noted that existing air guide plates are usually large in size but thin in thickness (small cross-sectional depth), with a small moment of inertia and poor structural rigidity. Therefore, if the suspended section is unrestrained, it is easy to cause insufficient modal characteristics of the air guide plate, which can easily lead to resonance. Resonance can also cause abnormal noise, affecting the durability and functionality of the air guide plate.

[0053] To address the aforementioned issues, this application provides a damping component, a wind deflector structure, and a vehicle. By effectively constraining the first and second suspended portions, a flexible connection between the first and second target components is achieved. It is understood that this flexible connection can be a flexible connection between two wind deflectors or a flexible connection between the wind deflector and surrounding automotive components. The design of the damping component allows for relative movement between the two target components while providing damping constraints, ensuring the stability of the connection, reducing vibration transmission, minimizing resonance and abnormal noise, and improving the durability and functionality of the entire vehicle.

[0054] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0055] The following will combine Figures 1 to 6 The embodiments of this application will be described below.

[0056] Reference Figures 1 to 4As shown in the embodiment of this application, a damping member 100 is provided for being disposed between a first target member 10 and a second target member 20. The first target member 10 includes a first fixed part 11 and a first suspended part 12, and the second target member 20 includes a second fixed part 21 and a second suspended part 22. The first fixed part 11 and the second fixed part 21 are fixed on the vehicle.

[0057] Optionally, the damping component 100 can be applied to components such as radiator air deflectors, body panels, and suspension systems of vehicles such as automobiles, trucks, and buses to reduce resonance, improve stability, and extend service life. For example, the first target component 10 and the second target component 20 can be the first air guide portion 210 and the second air guide portion 220 in the air guide structure 200, respectively.

[0058] It is understood that the first target component 10 and the second target component 20 can be combinations of the first air guide portion 210 and the second air guide portion 220 of the air guide structure 200, or combinations of the air guide structure 200 with surrounding automotive components (such as the anti-collision beam 310), or combinations applicable to other automotive components that have modal insufficiency due to their lack of self-constraint and are prone to resonance problems. No restrictions are imposed here.

[0059] Reference Figures 4 to 6 As shown, the damping member 100 includes a first connecting part 110 and a second connecting part 120, wherein the first connecting part 110 is provided with a first connecting structure 111, which is used to connect the first suspended part 12.

[0060] Optionally, the first connection structure 111 may include a hook, clip, slot, threaded hole or other fastening structure to ensure a stable connection with the first suspended part 12.

[0061] The second connecting part 120 is arranged along the axial direction of the first connecting part 110. The second connecting part 120 is provided with a second connecting structure 121, which is used to connect the second suspended part 22.

[0062] Optionally, similar to the first connecting structure 111, the second connecting structure 121 may include hooks, clips, slots, sockets, threads or other fastening structures to accommodate the shape and size of the second suspended portion 22.

[0063] Specifically, during installation, the first connecting part 110 is connected to the first suspended part 12 of the first target part 10 through its first connecting structure 111, while the second connecting part 120 is connected to the second suspended part 22 of the second target part 20 through its second connecting structure 121. This connection design can effectively constrain the suspended parts of the first target part 10 and the second target part 20, thereby reducing resonance.

[0064] Optionally, the material of the damping element 100 may have good elasticity and durability to adapt to vibration and temperature changes during vehicle operation. For example, the material of the damping element 100 may include rubber, plastic, elastic metal alloy, etc.

[0065] As can be seen, the damping component 100 provided in this application achieves a flexible connection between the first target component 10 and the second target component 20 by effectively constraining the first suspended part 12 and the second suspended part 22. It can be understood that this flexible connection can be a flexible connection between two air guides or a flexible connection between the air guide and the surrounding automotive components. The design of the damping component 100 allows relative movement between the two target components while providing damping constraints, ensuring the stability of the connection, reducing vibration transmission, reducing resonance and abnormal noise, and improving the durability and functionality of the entire vehicle.

[0066] Optional, combined Figure 2 and Figure 3 Two damping elements 100 may be provided, and both damping elements 100 are located near the middle of the connection surface between the first target element 10 and the second target element 20.

[0067] Optionally, the damping component is integrally molded.

[0068] In some embodiments, combined with Figure 1 and Figure 2 The damping component 100 is a rubber component.

[0069] The damping element 100 is made of rubber. The elastic properties of rubber allow the damping element 100 to deform when subjected to external forces, thereby absorbing and dispersing vibration energy. The rubber damping element 100 is mainly used between two target components (first target component 10 and second target component 20) on the vehicle. This design further reduces or eliminates resonance and abnormal noise caused by the suspended parts of the target components (first suspended part 12 and second suspended part 22) during vehicle operation.

[0070] In addition, the weather resistance and corrosion resistance of rubber ensure the stability and reliability of the damping component 100 during long-term use.

[0071] In some embodiments, combined with Figure 3 , Figure 5 and Figure 6 The first connecting structure 111 includes a fixing groove 1111, which is formed on the outer wall of the first connecting part 110 and is used to be engaged with the first suspended part 12.

[0072] Optionally, in actual design, the shape, size and position of the fixing groove 1111 can be designed according to the specific structure and size of the connection of the first suspended part 12 to ensure the locking effect and improve the connection stability.

[0073] In practical applications, firstly, the first connecting part 110 is aligned with the first suspended part 12 of the first target part 10 to ensure that the fixing groove 1111 matches the shape and size of the suspended part. Then, the damping member 100 is pushed into place by appropriate force so that the fixing groove 1111 is firmly locked on the suspended part.

[0074] Optionally, the mating point between the fixing groove 1111 and the first suspended part 12 may also be designed with an auxiliary fixing design, such as setting additional rubber gaskets, to further improve the stability of the connection.

[0075] As can be seen, the design of the fixing groove 1111 allows the damping element 100 to be firmly secured to the first suspended portion 12 of the first target element 10, thereby improving the stability and reliability of the connection. In addition, the design of the fixing groove 1111 simplifies the installation process of the damping element 100, reducing installation difficulty and cost.

[0076] In some embodiments, combined with Figure 4 and Figure 5 The first connecting part 110 has a first opening 110a, and the second connecting part 120 has a second opening 120a connected to the first opening 110a. The second opening 120a is for the second suspended part 22 to be inserted, and the second opening 120a constitutes the second connecting structure 121.

[0077] It is understood that the first port 110a is designed to be connected to the second port 120a. When the second suspended part 22 is inserted into the second port 120a, it can also pass through or penetrate the first port 110a.

[0078] Optionally, in some examples, the diameter of the first port 110a is larger than the diameter of the second port 120a, and the first connecting part 110 is designed to be located on the side of the second connecting part 120 facing the second suspended part 22. In this way, when the second suspended part 22 is inserted into the second port 120a, the first port 110a can provide guidance for the second suspended part 22, thus realizing the smooth insertion of the second suspended part 22.

[0079] In addition, the elastic properties of the rubber allow the first port 110a or the second port 120a to undergo moderate deformation during insertion to accommodate the shape and size differences between the first suspended portion 12 and the second suspended portion 22. This adaptability simplifies the installation process and improves the reliability and durability of the connection.

[0080] In practical applications, firstly, the first port 110a of the first connecting part 110 is aligned with the first suspended part 12 of the first target part 10 for initial positioning. Then, the second suspended part 22 of the second target part 20 is inserted through the first port 110a and moved axially to a preset position of the second port 120a, thus achieving a stable connection between the damping part 100 and the second suspended part 22. This design simplifies the installation process and improves the stability and adaptability of the connection.

[0081] In some embodiments, combined with Figure 5 The damping member 100 also includes a transition portion 130, which connects the first connecting portion 110 and the second connecting portion 120. The transition portion 130 is provided to taper from one end near the first connecting portion 110 to one end near the second connecting portion 120.

[0082] Understandably, the transition portion 130 is used to connect the first connecting portion 110 and the second connecting portion 120, and its shape and size can be designed to smoothly transition from the first connecting portion 110 to the second connecting portion 120. The gradually tapering design helps to provide better guidance and positioning during the connection process, and also enhances the connection stability between the damping member 100 and the second suspended portion 22.

[0083] Optionally, the transition section 130 is also designed to be made of rubber. The elasticity, weather resistance and corrosion resistance of rubber ensure the stability and reliability of the transition section 130 during long-term use.

[0084] In addition, the gradually tapering design of the transition section 130 helps to more effectively disperse and absorb vibration energy, reduce resonance and abnormal noise, and optimize the performance of the damping component 100 in terms of vibration reduction and noise reduction.

[0085] In some embodiments, combined with Figure 5 Multiple resistance elements 122 are provided along the axial direction on the inner wall of the second connecting part 120.

[0086] Optionally, the resistance element 122 can be designed in various shapes, such as protrusions, ribs, or corrugations, and can be selectively designed according to actual needs.

[0087] The resistance element 122 increases the friction between the damping element 100 and the second suspended part 22, thereby improving the stability of the damping element 100 during the connection process. In addition, during the vibration transmission process, the resistance element 122 can absorb and dissipate more vibration energy, reducing the generation of resonance and abnormal noise.

[0088] In addition, combined Figures 1 to 3 ,as well as Figure 6This application also provides an air guide structure 200, including: a damping member 100, a first air guide portion 210, and a second air guide portion 220 as described in any of the above possible embodiments. It is understood that the first air guide portion 210 and the second air guide portion 220 in this application embodiment can respectively correspond to the first target member 10 and the second target member 20 mentioned above.

[0089] The first air guide section 210 is provided with a first mating surface 211, which constitutes a first suspended section 12. The first mating surface 211 has an installation port 212 for accommodating the damping member 100. The installation port 212 is used for limiting the engagement with the first connecting structure 111. The installation section can be used to achieve a stable connection between the first suspended section 12 and the damping member 100.

[0090] The first connecting structure 111 can be a fixing groove 1111, and optionally, the fixing groove 1111 can be snapped into the mounting port 212.

[0091] The second air guide section 220 is provided with a second mating surface 221, which forms a second suspended section 22. An insert 222 is provided on the second mating surface 221 for insertion into the second connecting section 120. It can be understood that the insert 222 can be inserted into the second opening 120a to achieve the connection between the second suspended section 22 and the damping member 100.

[0092] Specifically, the first connecting part 110 of the damping component 100 is inserted into the mounting port 212 of the first air guide part 210, and a stable connection is achieved through limiting cooperation. Subsequently, the plug 222 of the second air guide part 220 is inserted into the second connecting part 120 of the damping component 100. During this process, the resistance element 122 on the inner wall of the second connecting part 120 will come into contact with the plug 222, increasing friction and connection stability.

[0093] Thus, in the improved air guide structure 200 of this application embodiment, the first air guide section 210 and the second air guide section 220 are flexibly connected by the damping member 100. The damping member 100 is used to absorb and dissipate energy during vibration transmission, reducing the generation of resonance and abnormal noise. Through the reasonable design of the damping member 100 and the structure of the first air guide section 210 and the second air guide section 220, the air guide structure 200 can effectively reduce the generation of wind noise and improve the comfort and service life of the vehicle.

[0094] In some embodiments, combined with Figure 6 The end of the plug 222 facing the damping member 100 is provided with a guide surface 222a.

[0095] Optionally, the guide surface 222a can be designed as a cone, arc, slope or any other shape that helps the insert 222 to smoothly enter the damping element 100, and the specific design can be selectively chosen according to actual needs.

[0096] The design of the guide surface 222a allows the insert 222 to be positioned more smoothly and accurately during insertion into the second connecting part 120 of the damping component 100. The guide surface 222a guides the insert 222 to smoothly enter the damping component 100, avoiding excessive resistance or damage to the damping component 100 during assembly, thereby enhancing the stability and assembly efficiency of the entire air guide plate structure 200.

[0097] In some embodiments, combined with Figure 6 The plug-in 222 is interference-fitted with the second connecting part 120. Specifically, the plug-in 222 is interference-fitted with the second connecting part 120 through the second port 120a.

[0098] Understandably, the outer diameter of plug 222 can be designed to be slightly larger than the inner diameter of the second port 120a to ensure an interference fit can be formed during assembly.

[0099] Thus, this design ensures that an appropriate interference fit can be formed between the plug-in 222 and the second connecting part 120 during the assembly process. The second connecting part 120 itself is made of elastic material. When the two are in an interference fit, the second connecting part 120 will generate an elastic compressive force on the plug-in 222, increasing the connection stability between the plug-in 222 and the second connecting part 120.

[0100] It is evident that the interference fit design can reduce the relative movement between the plug-in 222 and the damping component 100, enhance the stability and durability of the connection, and reduce the loosening of the assembly caused by vibration or external force by forming a tight fit.

[0101] In addition, this application also provides a vehicle including the damping element 100 in any of the above possible embodiments, and / or the air guide structure 200 in any of the above possible embodiments.

[0102] The vehicle provided in this application embodiment is designed with the aforementioned damping element 100 and / or air guide structure 200.

[0103] By effectively constraining the first suspended part 12 and the second suspended part 22, a flexible connection between the first target part 10 and the second target part 20 is achieved. It can be understood that this flexible connection can be a flexible connection between two air guides or a flexible connection between the air guide and the surrounding automotive parts. The design of the damping part 100 allows relative movement between the two target parts while providing damping constraints, ensuring the stability of the connection, reducing vibration transmission, reducing resonance and abnormal noise, and improving the durability and functionality of the whole vehicle.

[0104] Through the reasonable design of the damping component 100 and the structure of the first air guide 210 and the second air guide 220, the air guide plate structure 200 can effectively reduce the generation of wind noise and improve the comfort and service life of the vehicle.

[0105] In some embodiments, combined with Figure 1 The vehicle includes a crash beam 310 and an upper crossbeam 320 of the radiator. The first air guide 210 is rigidly connected to the radiator 30, and the second air guide 220 is rigidly connected to the crash beam 310 or the upper crossbeam 320 of the radiator.

[0106] Thus, when the first air guide section 210 and the second air guide section 220 are flexibly connected by the damping member 100, relative movement between them is allowed, and a certain degree of damping constraint is provided, enhancing the constraint effect on the suspended part of the air guide plate structure 200. Finally, it should be noted that other embodiments of this application will be readily apparent to those skilled in the art upon considering the specification and practicing the application disclosed herein.
