The deflector 201 is connected to the front side of the mounting member 101, and the positioning member 202 engages with a positioning hole in the bumper to achieve installation and positioning.

[0039] Compared with the prior art, the air dam structure provided by the application directly inserts the positioning piece 202 into the positioning hole during installation, and the clamping piece 103 is clamped and matched with the clamping hole, so that the mounting piece 101 is positioned with the bumper, and the preliminary connection of the air dam structure is completed. Then, the air dam structure is fixed and installed on the bumper by connecting the fixing module with the bumper. The scheme in the application does not need to find the positioning point again during installation, and the clamping piece 103 is clamped and matched with the clamping block at the same time, so that the air dam structure and the bumper are prevented from being separated, and the air dam structure does not need to be lifted when the fixing module is used to lock the air dam structure and the bumper, the installation efficiency is improved, one-person operation can be realized, and the labor cost is reduced. In addition, the clamping piece 103 is clamped and matched with the clamping hole, and can jointly act with the fixing module to increase the stability and firmness of the connection between the air dam structure and the bumper.

[0040] Optionally, the clamping piece 103 is distributed with a plurality of clamping pieces in the left-right direction, and the clamping piece 103 is arranged one-to-one with the clamping hole of the bumper. The plurality of clamping pieces 103 are clamped and matched with the corresponding clamping holes, respectively, so that the stability and firmness of the connection with the bumper are increased.

[0041] Optionally, the plurality of positioning pieces 202 distributed on the flow guide piece 201 in the left-right direction, the bumper has a plurality of positioning holes, and the positioning piece 202 is arranged one-to-one with the positioning hole. The plurality of positioning pieces 202 can improve the accuracy of positioning and avoid deviation in positioning.

[0042] Optionally, the mounting piece 101, the clamping piece 103, the flow guide piece 201 and the positioning piece 202 are integrated components.

[0043] In some embodiments, referring to Figure 4 The clamping piece 103 includes two clamping blocks that are mirror-symmetrically arranged based on a first plane as a reference plane, the first plane is perpendicular to the mounting piece 101, and the two clamping blocks form a spacing space in a 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 piece 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, the clamping body 1031 protrudes away from the side of 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 piece, as long as the two clamping blocks have a spacing space in the first path (perpendicular to the first plane) and can approach and move away from each other.

[0045] In the installation, the positioning member 202 is inserted into the positioning hole, and the clamping bodies 1031 on the two clamping blocks are pressed by the inner wall of the clamping hole to be close to each other, and then inserted into the clamping hole. After the clamping bodies 1031 completely pass through the clamping hole, the connecting bodies 1032 are inserted into the clamping hole, the clamping bodies 1031 are reset and abut against the bumper, thereby realizing the preliminary connection of the mounting member 101 and the bumper. The two clamping blocks have a spacing space, so that the two clamping bodies 1031 can be close to each other when the clamping bodies 1031 are inserted into the clamping hole, so as to realize that the two clamping bodies 1031 completely pass through the clamping hole and abut against the bumper. The scheme in the embodiment can realize pre-installation while positioning, improve the installation efficiency, and is convenient to operate, can realize single-person installation, and saves the labor cost.

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

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

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

[0049] In the process that the clamping body 1031 enters the clamping hole, the guide inclined surface 1033 abuts against the inner circumferential surface of the clamping hole, so as to reduce the friction resistance between the clamping body 1031 and the inner circumferential surface of the clamping hole, thereby facilitating the clamping body 1031 to pass through the clamping hole.

[0050] In some embodiments, please refer to Figures 2 to 3 The fixing module comprises a first connecting hole 102 arranged in the mounting member 101, the first connecting hole 102 is matched with a second connecting hole of the bumper, and a fixing member 105 is inserted into the first connecting hole 102 and the second connecting hole.

[0051] The fixing member 105 is inserted into the first connecting hole 102 and the second connecting hole, thereby realizing the connection of the mounting member 101 and the bumper. The scheme in the embodiment can quickly connect the mounting member 101 and the bumper, and has simple structure and convenient processing. The fixing member 105 can adopt a standard part, thereby reducing the production cost.

[0052] As a specific embodiment of the fixing module, the fixing member 105 comprises a bolt and a nut screwed with the bolt, the bolt is inserted into the first connecting hole 102 and the second connecting hole, and the nut is screwed with the bolt to lock the mounting member 101 with 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 embedded connection or integral locking of one part with another part, and is usually used for coupling of plastic parts, and the material thereof is usually composed of plastic material with certain flexibility. The biggest feature of the buckle connection is convenient installation and disassembly, and tool-free disassembly can be achieved. The buckle is composed of a positioning member 202 and a fastener. The positioning member 202 functions to guide the buckle to reach the installation position smoothly, correctly and quickly during installation. The fastener functions as follows: the detachable fastener is usually designed to be separated when a certain separation force is applied, and the two connecting parts are separated. Such buckle is often used to connect two parts that need to be frequently disassembled. The non-detachable fastener needs to be manually deflected to separate the two parts, and is often used for connection and fixation of parts that are not disassembled during use.

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

[0055] The air flow flows from the front to the flow guide body 2011, and since the bottom of the flow guide body 2011 is an arc-shaped flow guide surface, the air flow flows from the middle to the two sides, reducing the frontal wind resistance of the flow guide body 2011. The transition area 2012 makes the air flow flowing to the end of the flow guide body 2011 flow uniformly and stably to the side body 2013, reducing the resistance in the process of air flow flowing from the flow guide body 2011 to the side body 2013.

[0056] As a specific embodiment of the mounting member 101, referring to Figure 2 , the mounting member 101 comprises a body and a plurality of reinforcing bodies respectively arranged on both sides of the body, the body is connected with the flow guide body 2011, and the reinforcing bodies are connected with the side body 2013 or the transition area 2012.

[0057] The scheme in the embodiment can ensure the stability of the connection between the mounting piece 101 and the bumper, avoid interference of adjacent components of the mounting piece 101, and be easier to process.

[0058] It should be noted that the clamping piece 103 is arranged on the body, and the mounting module has a plurality of mounting modules, and the plurality of mounting modules are arranged on the body and the reinforcing body respectively.

[0059] In some embodiments, referring to Figure 5 , the bottom of the transition area 2012 is upwardly bent to form a spoiler 2012-1.

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

[0061] In some embodiments, referring to Figure 3 and Figure 7 , the mounting assembly 10 further comprises a limiting piece 104 arranged on the mounting piece 101, the limiting piece 104 abuts against the bottom of the bumper, and the mounting piece 101 and the bumper form a gap in the up-down direction.

[0062] The limiting piece 104 forms a gap after the mounting piece 101 is connected to the bumper, so that the airflow can pass through during the driving of the vehicle, and the mounting piece 101 and the bumper can be prevented from being rigidly collided, thereby improving the service life.

[0063] As a specific embodiment of the limiting piece 104, referring to Figures 2 to 3 , the limiting piece 104 comprises a first limiting strip, a second limiting strip and a third limiting strip connected in sequence, and the first limiting strip and the third limiting strip are symmetrically connected to two ends of the second limiting strip.

[0064] The scheme in the embodiment can increase the contact area between the limiting piece 104 and the bumper, and prevent the bumper from shaking after being connected to the mounting piece 101 due to the abutting force of the limiting piece 104.

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