[0002] In recent years, in order to achieve the goals of reducing fuel consumption, reducing environmental pollution and saving resources, the automotive industry is vigorously conducting research in two aspects: one is to improve aerodynamics; the other is to promote the lightweight of automobiles. The air dam of an automobile is a component that improves aerodynamic performance. The air dam is generally installed below the front end of a motor vehicle. The low ground clearance formed by the air dam allows the airflow that should flow into the bottom of the vehicle to flow out from both sides of the vehicle, avoiding high-speed airflow directly impacting the chassis to reduce the formation of vortices, improving the aerodynamic resistance of the vehicle when running at high speed, and improving the combustion efficiency of fuel.

[0003] Existing air dams are usually connected to the bumper with clips and have no positioning structure. During installation, multiple people are required to cooperate, with one person finding the positioning point and lifting the air dam, and the other using a connector to connect the air dam to the bumper. This method not only results in low installation efficiency, but also increases labor costs. Summary of the invention

[0038] Please also read Figures 1 to 5 The air dam structure, bumper assembly and vehicle provided by the present invention are now described. The air dam structure includes a mounting assembly 10 and a guide assembly 20. The mounting assembly 10 includes a mounting member 101 and a fixing module and a clamping member 103 respectively connected to the mounting member 101. The clamping member 103 is clamped with the clamping hole of the bumper to achieve pre-installation. The fixing module is detachably connected to the bumper. The guide assembly 20 includes a guide member 201 and a positioning member 202 provided on the guide member 201. The guide member 201 is connected to the front side of the mounting member 101. The positioning member 202 is plugged with the positioning hole of the bumper to achieve installation and positioning.

[0039] Compared with the prior art, the air dam structure provided by the present invention directly inserts the positioning member 202 into the positioning hole during installation, and the clamping member 103 is clamped and matched with the clamping hole to realize the positioning of the mounting member 101 and the bumper, and completes the preliminary connection of the air dam structure. Then, it is connected to the bumper through the fixing module to realize the fixed installation of the air dam structure on the bumper. The solution in the present invention does not need to re-find the positioning point during installation, and the clamping member 103 and the clamping block are clamped at the same time as the positioning to avoid the separation of the air dam structure and the bumper. When the air dam structure and the bumper are locked by the fixing module, there is no need to lift the air dam structure, which improves the installation efficiency, and can realize single-person operation and reduce labor costs. In addition, the clamping member 103 is clamped with the clamping hole, and can also work together with the fixing module to increase the stability and firmness of the connection between the air dam structure and the bumper.

[0040] Optionally, there are multiple clamping members 103 distributed along the left and right directions, and the clamping members 103 are arranged one by one corresponding to the clamping holes of the bumper. The multiple clamping members 103 are respectively clamped with the corresponding clamping holes, which increases the connection stability and firmness with the bumper.

[0041] Optionally, the guide member 201 has a plurality of positioning members 202 distributed along the left-right direction, the bumper has a plurality of positioning holes, and the positioning members 202 are arranged one-to-one with the positioning holes. Providing a plurality of positioning members 202 can improve the accuracy of positioning and avoid positioning deviation.

[0042] Optionally, the mounting member 101, the clamping member 103, the flow guide member 201 and the positioning member 202 are an integrated component.

[0043] In some embodiments, see Figure 4 The clamping member 103 includes two clamping blocks which are arranged in a mirror-symmetrical manner with the first plane as a reference plane. The first plane is perpendicular to the mounting member 101, and the two clamping blocks form a spacing space on the first path. The first path is perpendicular to the first plane. The clamping block includes a connecting body 1032 and a clamping body 1031. The connecting body 1032 is connected to the mounting member 101, and the connecting body 1032 is inserted into the clamping hole; the clamping body 1031 is arranged on the top of the connecting body 1032, and the clamping body 1031 protrudes to the side away from the other clamping block, and the clamping body 1031 abuts against the bumper.

[0044] It should be noted that the first plane can be any plane perpendicular to the mounting member, as long as the two clamping blocks have a spacing in the first path (perpendicular to the first plane) and can move closer to or farther from each other.

[0045] During installation, the positioning member 202 is plugged into the positioning hole, and the clamping bodies 1031 on the two clamping blocks are squeezed by the inner wall of the clamping hole and approach each other, and then inserted into the clamping hole. After the clamping body 1031 completely passes through the clamping hole, the connecting body 1032 is inserted into the clamping hole, and the clamping body 1031 is reset and abuts against the bumper, thereby realizing the preliminary connection between the mounting member 101 and the bumper. There is a spacing space between the two clamping blocks, so that when the clamping body 1031 is inserted into the clamping hole, the two clamping bodies 1031 can approach each other, so as to realize that the two clamping bodies 1031 completely pass through the clamping hole, thereby abutting against the bumper. The scheme in this embodiment can realize pre-installation while positioning, improve installation efficiency, and is easy to operate, and can realize single-person installation, saving labor costs.

[0046] As another specific implementation of the clamping member 103, please refer to Figure 4 The clamping member 103 further includes a reinforcing sheet disposed in the spacing space, and two sides of the reinforcing sheet are respectively connected to the two connecting bodies 1032 .

[0047] The solution in this embodiment can limit the two connecting bodies 1032 when the two clamping bodies 1031 are close to each other, so as to prevent the connecting bodies 1032 from being separated from the mounting member 101 due to deformation. At the same time, the reinforcement sheet can increase the connection stability between the two clamping blocks, so as to prevent the two clamping blocks from being damaged due to excessive deformation during installation.

[0048] In some embodiments, see Figure 4 The width of the engaging body 1031 on the first path gradually increases from top to bottom, so that a guiding inclined surface 1033 is formed on the side of the engaging body 1031 away from the other engaging block.

[0049] When the engaging body 1031 enters the engaging hole, the guiding inclined surface 1033 abuts against the inner peripheral surface of the engaging hole, thereby reducing the friction resistance between the engaging body 1031 and the inner peripheral surface of the engaging hole, making it easier for the engaging body 1031 to pass through the engaging hole.

[0050] In some embodiments, see Figures 2 to 3 The fixing module includes a first connecting hole 102 opened in the mounting member 101, the first connecting hole 102 is adapted to the second connecting hole of the bumper, and a fixing member 105 inserted into the first connecting hole 102 and the second connecting hole.

[0051] The fixing member 105 is inserted into the first connection hole 102 and the second connection hole, thereby realizing the connection between the mounting member 101 and the bumper. The solution in this embodiment can quickly connect the mounting member 101 to the bumper, and has a simple structure and convenient processing. The fixing member 105 can use a standard part, which reduces the production cost.

[0052] As a specific implementation of the fixing module, the fixing member 105 includes a bolt and a nut threadedly connected to the bolt, the bolt is inserted into the first connecting hole 102 and the second connecting hole, and the nut is threadedly connected to the bolt to lock the mounting member 101 to the bumper.

[0053] As another specific embodiment of the fixing module, the fixing member 105 is a plastic buckle. The buckle is a mechanism for embedding and connecting one part with another part or locking the whole part, and is usually used for connecting plastic parts. Its material is usually made of plastic material with a certain flexibility. The biggest feature of the buckle connection is that it is easy to install and disassemble, and can be disassembled without tools. The buckle is composed of a positioning member 202 and a fastener. The role of the positioning member 202 is to guide the buckle to reach the installation position smoothly, correctly and quickly during installation. The role of the fastener is: the detachable fastener is usually designed so that when a certain separation force is applied, the buckle will disengage and the two connecting members will separate. This buckle is often used to connect two parts that need to be disassembled frequently. Non-detachable fasteners require the fastener to be manually deflected before the two parts can be disassembled, and are mostly used for connecting and fixing parts that are not disassembled during use.

[0054] In some embodiments, see Figure 1 and Figure 3 The guide member 201 includes a guide body 2011 and two side enclosures 2013. The guide body 2011 is connected to the front side of the bumper. The guide body 2011 extends in the left-right direction. The thickness of the guide body 2011 in the up-down direction gradually increases from the middle to both sides, so that the bottom of the guide body 2011 forms an arc-shaped guide surface. The two side enclosures 2013 are respectively connected to the left and right sides of the guide body 2011. Each side enclosure 2013 is arranged at an angle with the guide body 2011 and extends to the rear side of the guide body 2011. The connection between the side enclosure 2013 and the guide body 2011 has an arc-shaped transition zone 2012.

[0055] The airflow flows from the front to the guide body 2011. Since the bottom of the guide body 2011 is an arc-shaped guide surface, the airflow flows from the middle to both sides, reducing the front wind resistance of the guide body 2011. The transition area 2012 allows the airflow flowing to the end of the guide body 2011 to flow toward the side enclosure 2013 evenly and stably, reducing the resistance of the airflow in the process of flowing from the guide body 2011 to the side enclosure 2013.

[0056] As a specific implementation of the mounting member 101, please refer to Figure 2 The mounting member 101 includes a main body and a plurality of reinforcing bodies respectively arranged on both sides of the main body. The main body is connected to the guide body 2011 , and the reinforcing bodies are connected to the side enclosure 2013 or the transition zone 2012 .

[0057] The solution in this embodiment ensures the stability of the connection between the mounting member 101 and the bumper, avoids interference between adjacent parts of the mounting member 101, and is easier to process.

[0058] It should be noted that the clamping member 103 is arranged on the main body, and there are multiple mounting modules, which are respectively arranged on the main body and the reinforcement body.

[0059] In some embodiments, see Figure 5 The bottom of the transition zone 2012 is bent upward to form a spoiler 2012-1.

[0060] The spoiler 2012-1 is bent upward, and when the airflow passes through this part, the velocity of the airflow can be increased, the wind resistance can be reduced, and the fuel consumption of the vehicle can be reduced during driving.

[0061] In some embodiments, see Figure 3 and Figure 7 The mounting assembly 10 further includes a stopper 104 disposed on the mounting member 101 , the stopper 104 abuts against the bottom of the bumper, so that a clearance is formed between the mounting member 101 and the bumper in the up-and-down direction.

[0062] The limiting member 104 forms a clearance gap after the mounting member 101 is connected to the bumper, which can allow airflow to pass through and avoid rigid collision between the mounting member 101 and the bumper during vehicle driving, thereby increasing the service life.

[0063] As a specific implementation of the stopper 104, please refer to Figures 2 to 3 The limiting member 104 includes a first limiting bar, a second limiting bar and a third limiting bar connected in sequence, and the first limiting bar and the third limiting bar are symmetrically connected to both ends of the second limiting bar.

[0064] The solution in this embodiment can increase the contact area between the limiting member 104 and the bumper, thereby preventing the bumper from shaking due to the abutment force of the limiting member 104 after being connected to the mounting member 101 .

[0065] Specifically, the first limiting strip and the third limiting strip are both arranged at an angle to the second limiting strip.

[0066] Based on the same inventive concept, the present invention also provides a bumper assembly. Figures 6 to 9 The bumper assembly includes any one of the air dam structures described above, a bumper body 30 connected to the mounting member 101 , and a lower air deflector 40 connected to the bumper body 30 .

[0067] The bumper assembly provided by the present invention adopts the above-mentioned air dam structure and has similar beneficial effects as the above-mentioned air dam structure, which will not be described in detail here.

[0068] In some embodiments, see Figure 8 The bottom of the bumper body 30 has a shielding rib 301, which is located in front of the air guide 201 and forms a shielding space between the shielding rib 301 and the air guide 201 in the front-to-back direction.

[0069] The shielding rib 301 can shield the connection between the air dam structure and the bumper body 30 to prevent leakage therefrom, which not only reduces the airflow entering therefrom and thus affects the stability of the connection, but also improves the overall aesthetics.

[0070] Based on the same inventive concept, the present invention also provides a vehicle, which includes any one of the above-mentioned bumper assemblies.

[0071] The vehicle provided by the present invention adopts the above-mentioned bumper assembly and has similar technical effects as the above-mentioned bumper assembly, which will not be described in detail here.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
