Description

Technical Field

[0001] This invention relates to the field of automotive air deflector technology, and in particular to an air deflector structure, installation method, and automobile. Background Technology

[0002] With the increase in families having two or three children, the demand for 6 / 7-seat cars has surged, with sales of large / mid-size six-seat SUVs skyrocketing by 90.9% year-on-year. The front fascia of these vehicles is also becoming larger, with taller bodies and greater ground clearance. This overall increase in vehicle size makes airflow management more challenging. The size of the air deflector must be compatible with the overall vehicle size. To accommodate large / mid-size six-seat SUVs, the air deflector also needs to be larger. However, larger air deflectors require more assembly space. Typically, the front bumper is installed after the air deflector, but a larger air deflector may interfere with the front bumper installation. Firstly, it may obstruct the view of the front bumper during installation, making it difficult to secure the bumper's fasteners. Secondly, the front edge of a larger air deflector may press against the worker's arm during bumper installation, affecting assembly and causing discomfort. Furthermore, larger air deflectors also present challenges in handling and positioning. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a wind deflector structure, installation method and automobile to solve the above problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, there is an air guide plate structure, the air guide plate including an integrally formed front air guide plate body and a rear air guide plate body, the front air guide plate body and the rear air guide plate body are connected by a connecting part, the thickness of the connecting part is less than the thickness of the front air guide plate body and the rear air guide plate body, so that the front air guide plate body can be flipped relative to the rear air guide plate body through the connecting part, and the top surfaces of the front air guide plate body and the rear air guide plate body are respectively provided with ear plates on one side close to each other, and the front air guide plate body and the rear air guide plate body are fixedly connected by the ear plates and fasteners.

[0005] As a further implementation, the front body of the air guide plate, the rear body of the air guide plate, and the connecting part are integrally injection molded using PP-T20. After the air guide plate is unfolded, the top surfaces of the front body, the rear body, and the connecting part of the air guide plate are flush.

[0006] As a further implementation, the bottom surface of the air guide plate is provided with a groove at the corresponding connection position to reduce the thickness of the connection, which is 0.7-0.9mm.

[0007] As a further implementation, the top surfaces of the front body and the rear body of the air guide plate are provided with reinforcing plates close to each other on one side, and multiple ear plates are provided on the reinforcing plates. The ear plates include front ear plates and rear ear plates respectively provided on the front body and the rear body of the air guide plate.

[0008] As a further implementation, the front ear plate and the rear ear plate are respectively provided, and the front ear plate and the rear ear plate are fixedly connected by a snap-fit ​​assembly.

[0009] As a further implementation, a vertical plate is provided on the rear side of the air guide plate body, and the vertical plate is provided with positioning holes and fixing holes.

[0010] As a further implementation, the edge of the air guide plate is provided with a sponge strip, which is broken at the end of the corresponding connecting part.

[0011] As a further implementation, the width of the front body of the air guide plate is less than the height difference between the air guide plate and the front bumper after installation.

[0012] Secondly, an installation method for an air guide plate structure, wherein the air guide plate is first fixedly connected to the main body of the vehicle body through the rear pillar, and then the front body of the air guide plate is allowed to hang down naturally by not setting any fixing parts at the ear plate, so as to provide a view for the installation of the front bumper. Then install and fix the front bumper. After the front bumper is fixed, flip the front body of the air deflector so that it is flush with the rear body of the air deflector. Connect the front ear plate on the front body of the air deflector and the rear ear plate on the rear body of the air deflector. Then use the clip assembly to pass through the ear plate to fix the front body of the air deflector and the rear body of the air deflector relative to each other.

[0013] Thirdly, a type of automobile, wherein the automobile body is equipped with an air deflector structure as described above, wherein the width of the front body of the air deflector is less than the height difference between the air deflector and the front bumper after installation.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention designs the air guide plate as a hinged flip structure in which the front body and the rear body of the air guide plate are integrally formed by a thin-walled connecting part. This allows the front body of the air guide plate to hang naturally relative to the rear body of the air guide plate before the front bumper is installed, effectively shortening the length occupied by the air guide plate in the front-rear direction (X direction) of the vehicle, providing workers with sufficient assembly operation space, solving the problem of large-sized air guide plates obstructing the front bumper installation view, and enabling workers to easily find and install the various fasteners of the front bumper.

[0015] 2. When the front body of the air guide plate of the present invention is installed on the front bumper, it is in a drooping state, and its front edge is far away from the worker's arm operation area. This avoids the problem of the worker's arm being hit and cut by the front edge of the air guide plate when pushing the front bumper forward, effectively protecting the worker's operation safety and improving the assembly comfort.

[0016] 3. The front and rear bodies of the air guide plate are integrally injection molded. The thickness of the connecting part is only 0.7-0.9mm and the width is about 5mm. This ensures that there will be no local glue shortage or breakage due to the thin wall during the integral injection molding process. It also allows the front body of the air guide plate to rotate around the connecting part within a certain range. The structure is simple and reliable, and no additional hinge parts are required, which reduces manufacturing costs and the number of parts.

[0017] 4. After the front body of the air guide plate is flipped and folded, the overall physical space can be effectively compressed by about 35%, which facilitates storage and transportation, reduces logistics costs, and at the same time increases the actual operating space of workers within the limited assembly operation space of the whole vehicle, ensuring that there is no contact with the surrounding parts of the vehicle body during the assembly process, and achieving smooth assembly operation.

[0018] 5. The front ear plate on the rear body of the air guide plate and the rear ear plate on the front body of the air guide plate are locked and fixed by a buckle assembly. After the air guide plate is unfolded and aligned, the relative positions of the two can be reliably locked to ensure the structural stability of the air guide plate during the operation of the vehicle and prevent the front body from accidentally flipping over due to vibration, airflow impact and other reasons.

[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Example 1 In a typical embodiment of the present invention, reference is made to Figures 1-5 As shown, an air guide structure is mainly used in the front compartment area of ​​large / medium-sized SUVs and other vehicles. It is installed at the front of the vehicle body and behind the front bumper to guide airflow to the radiator and at the same time achieve the sealing of the front compartment.

[0025] like Figure 1 and Figure 2 As shown, the overall structure of the air guide plate includes a front body 1, a rear body 2, a connecting part 3, a groove 4, a reinforcing plate 5, a rear ear plate 6, a front ear plate 7, a buckle assembly 8, a vertical plate 9, a positioning hole 10, a fixing hole 11, and sponge strips 12, 13, 14, and 15.

[0026] The front body 1 and the rear body 2 of the air guide plate are integrally injection molded structures, and are connected by a connecting part 3. The thickness of the connecting part 3 is less than the thickness of the front body 1 and the rear body 2 of the air guide plate, so that the front body 1 can be flipped relative to the rear body 2 of the air guide plate through the connecting part 3. In the unfolded state of the air guide plate, the top surfaces of the front body 1, the connecting part 3, and the rear body 2 of the air guide plate are flush with each other, forming a complete top surface of the air guide plate.

[0027] In an optional example, the front body 1 of the air guide plate, the rear body 2 of the air guide plate, and the connecting part 3 are integrally injection molded from PP-T20 (polypropylene with 20% talc filler).

[0028] It is understandable that PP-T20 material has good rigidity and toughness, which can ensure the overall structural strength of the air guide plate while enabling the connecting part 3 to have sufficient bending toughness in the thin-walled state, thereby realizing the flipping function of the front body 1 of the air guide plate.

[0029] like Figure 2 As shown, the connecting part 3 is a thin-walled plastic strip structure with a thickness of 0.7-0.9 mm and a width of approximately 5 mm. A groove 4 is provided on the bottom surface of the air guide plate at the position corresponding to the connecting part 3. The groove 4 is provided to ensure that the thickness of the connecting part 3 is less than the thickness of the front body 1 and the rear body 2 of the air guide plate, so that the thickness of the connecting part 3 reaches the aforementioned range.

[0030] If the thickness of the connecting part 3 is too large, the flipping resistance of the front body 1 of the air guide plate will be too large, and the front body 1 of the air guide plate will not be able to hang down smoothly and naturally; if the thickness is too small, local missing glue or breakage problems are likely to occur during the injection molding process, affecting the product yield.

[0031] After verification, a thickness range of 0.7-0.9mm can ensure the smooth flow of plastic melt during injection molding and avoid local missing glue, while also giving the connecting part 3 sufficient bending toughness, allowing the front body 1 of the air guide plate to freely rotate around the connecting part 3 within a certain angle range, realizing the conversion between the folded state and the unfolded state.

[0032] Since the front body 1 and the rear body 2 of the air guide plate are integrally formed through the connecting part 3, no additional hinge parts are required, which reduces the number of parts and lowers the manufacturing cost. At the same time, it avoids problems such as loosening and corrosion that may occur during long-term use of independent hinge parts, thus improving the structural reliability.

[0033] like Figures 1-3 As shown, reinforcing plates 5 are respectively provided on the top surfaces of the front body 1 and the rear body 2 of the air guide plate that are close to each other. The reinforcing plates 5 extend along the edges of the front body 1 and the rear body 2 of the air guide plate to enhance the structural strength of the area and prevent deformation or cracking during repeated flipping and locking.

[0034] Multiple ear plates are provided along the length of the reinforcing plate 5. The ear plate provided on the rear body 2 of the air guide plate is the rear ear plate 6, and the ear plate provided on the front body 1 of the air guide plate is the front ear plate 7. The front ear plate 7 and the rear ear plate 6 are in one-to-one correspondence in position. When the front body 1 of the air guide plate is flipped open and flush with the rear body 2 of the air guide plate, the front ear plate 7 and the rear ear plate 6 are connected to each other to form an ear plate combination structure into which the snap-fit ​​assembly 8 can be inserted.

[0035] The clip assembly 8 is a plastic clip structure that passes through the corresponding front ear plate 7 and rear ear plate 6 and locks in place, reliably fixing the front body 1 and rear body 2 of the air guide plate into one unit. The clip assembly 8 is evenly distributed along the length of the air guide plate to ensure that all positions are subjected to uniform fixing force after the air guide plate is unfolded, preventing relative displacement or flipping between the front body 1 and rear body 2 of the air guide plate due to vibration or airflow impact during vehicle operation.

[0036] In this embodiment, the front ear plate 7, the rear ear plate 6, and the buckle assembly 8 are provided in three sets. In other examples, the number of sets can be increased appropriately.

[0037] It should be noted that during the stage of installing the rear body 2 of the air deflector to the rear of the vehicle body and before the front bumper is installed, the clip assembly 8 is not installed between the front ear plate 7 and the rear ear plate 6. At this time, due to the thinness and low bending stiffness of the connecting part 3, the front body 1 of the air deflector will naturally hang downward relative to the rear body 2 of the air deflector under the action of gravity, thereby detaching the front body 1 of the air deflector from the installation area of ​​the front bumper, providing the worker with ample vision and operating space. After the front bumper is installed and fixed, the worker flips the front body 1 of the air deflector upward to a position flush with the rear body 2 of the air deflector, aligns it with the front ear plate 7 and the rear ear plate 6, and inserts the clip assembly 8 to complete the final fixation of the air deflector.

[0038] like Figure 1 As shown, a vertical plate 9 is provided on the rear side of the rear body 2 of the air guide plate. The vertical plate 9 extends upward along the rear edge of the rear body 2 of the air guide plate and is integrally formed with the rear body 2 of the air guide plate. The vertical plate 9 is provided with positioning holes 10 and fixing holes 11. The positioning holes 10 are used to cooperate with the positioning pins corresponding to the vehicle body to achieve precise positioning of the air guide plate during installation and prevent the air guide plate from shifting before the fixing bolts are tightened. The fixing holes 11 are used to pass through the fixing bolts to firmly fix the rear body 2 of the air guide plate to the vehicle body.

[0039] Specifically, fixing holes 11 are located at both ends of the upright plate, and positioning holes 10 are located near the middle of the upright plate. Through the cooperation of positioning holes 10 and fixing holes 11 on the upright plate 9, the rear body 2 of the air guide plate can be reliably fixed in the predetermined position in the front compartment of the vehicle body, ensuring the assembly accuracy and connection strength between the air guide plate and the vehicle body.

[0040] like Figure 1 As shown, the edge of the air guide plate is provided with a sponge strip 12. The sponge strip is made of slow-rebound EPDM (ethylene propylene diene monomer rubber) material, which has excellent elastic recovery performance and weather resistance. The sponge strip is fixed to the edge and specific positions inside the air guide plate body by adhesive, so as to achieve contact sealing between the air guide plate and the front bumper and body sheet metal.

[0041] The sponge strips are arranged at different edges of the air guide plate to cover all the seams around the air guide plate that need to be sealed. The sponge strips are broken at the ends of the corresponding connecting parts 3 to prevent them from crossing the area of ​​the connecting parts 3 and to prevent them from being pulled off or damaged when the front body 1 of the air guide plate is flipped.

[0042] The air guide plate is provided with openings in the middle and rear positions. The edges of the openings are also provided with sponge strips. The middle opening is provided with sponge strip 13, the rear opening is provided with sponge strip 14, and the rear edge of the air guide plate body is provided with sponge strip 15. The rear edge of the air guide plate body is used to seal with the rear beam through sponge strip 15.

[0043] The openings are designed to avoid the engine hood latch bracket and latch cable bracket, which are existing technologies. The sponge strip at the opening is used to achieve a tight seal with the corresponding structure.

[0044] By installing sponge strips at the openings, the relevant supports are effectively avoided, ensuring that the air guide plate can be installed smoothly. At the same time, a seal is formed between the edge of the opening and the support to prevent airflow from leaking out of the openings and to ensure the overall airtightness of the front compartment.

[0045] Understandably, the width of the front body 1 of the air deflector (i.e., the dimension of the front body 1 of the air deflector in the longitudinal direction of the vehicle) is less than the height difference between the air deflector and the front bumper after installation. Specifically, when the rear body 2 of the air deflector is fixed to the rear of the vehicle body and the front body 1 of the air deflector hangs down naturally, the lower edge of the front body 1 of the air deflector is located above the installation position of the front bumper and will not interfere with the front bumper. The worker can have a sufficient field of vision when installing the front bumper, and at the same time, the front edge of the front body 1 of the air deflector will not enter the worker's arm operating area, reducing installation discomfort.

[0046] In this embodiment, the assembly length of the rear body 2 of the air guide plate in the vehicle's front-to-back direction (X direction) is approximately 240 mm, while the total X-direction length of the air guide plate after unfolding is approximately 367.8 mm, which is about 34.7% shorter when folded compared to the unfolded state. This size design allows workers to easily complete the assembly in a small operating space when installing the fixing bolts on both sides of the air guide plate, significantly improving assembly efficiency and operational comfort.

[0047] Example 2 In a typical embodiment of the present invention, an automobile is provided, wherein the air guide plate structure described in Embodiment 1 is installed on the automobile body, and the width of the front body 1 of the air guide plate is less than the height difference between the air guide plate and the front bumper after installation.

[0048] The vehicle in this embodiment is a large / mid-size SUV, featuring a tall body, high ground clearance, and a wide front fascia. Due to its large size, the front cabin space is relatively spacious, but the size of the air deflector is also correspondingly increased. The air deflector's extended length in the vehicle's longitudinal direction (X-axis) reaches approximately 367.8 mm, and it covers most of the front cabin opening in the vehicle's width direction (Y-axis).

[0049] The air deflector structure is installed in the front compartment of the car, located behind the front bumper and in front of the radiator. The rear body 2 of the air deflector is positioned by engaging with the positioning pin in the front compartment of the vehicle through the positioning hole 10 on the upright plate 9, and then the fixing bolt is inserted through the fixing hole 11 to reliably fix the rear body 2 of the air deflector to the vehicle body. After the rear body 2 of the air deflector is fixed, its top surface forms a sealed contact with the upper edge of the front compartment of the vehicle body, its bottom surface forms a seal with the lower edge of the front compartment of the vehicle body through a sponge strip, and its side edges form a seal with the side sheet metal of the vehicle body through sponge strips. This divides the opening area of ​​the front compartment into an air guiding channel, guiding the airflow to the radiator.

[0050] In the vehicle of this embodiment, after the air deflector is installed, there is a certain height difference between the top surface of the air deflector and the lower edge of the front bumper. The width (front-rear dimension) of the front body 1 of the air deflector is designed to be smaller than this height difference. Specifically, when the rear body 2 of the air deflector is fixed to the vehicle body, the front body 1 of the air deflector naturally droops relative to the rear body 2 of the air deflector under the action of gravity. At this time, the lower edge of the front body 1 of the air deflector is located above the lower edge of the front bumper, that is, the entire front body 1 of the air deflector is located above the front bumper mounting area and will not interfere with the front bumper.

[0051] This design ensures that during the installation of the front bumper, workers can clearly see all the mounting points and smoothly push the front bumper into place. Because the front body 1 of the air deflector hangs naturally away from the worker's arm operating area, the worker's arm will not touch the front edge of the front body 1 of the air deflector when pushing the front bumper forward, avoiding the discomfort of the arm being scratched by the air deflector.

[0052] After the vehicle assembly is completed, the front body 1 of the air guide plate is locked and fixed to the rear body 2 of the air guide plate through the front ear plate 7 and the rear ear plate 6 via the buckle assembly 8, so that the air guide plate is in an unfolded and flush state. The rear body 2 of the air guide plate is reliably fixed to the vehicle body through the positioning holes 10 and fixing holes 11 on the upright plate 9, and the overall structure of the air guide plate has good stability during the operation of the vehicle.

[0053] Because the front body 1 and the rear body 2 of the air guide plate are locked together by multiple evenly distributed snap-fit ​​assemblies 8, each fixing point evenly bears the load from airflow impact and vibration, preventing the air guide plate from deforming due to airflow impact or the front body from accidentally flipping over during high-speed driving. At the same time, the setting of the reinforcing plate 5 enhances the structural strength of the front ear plate 7 and the rear ear plate 6 area, ensuring the reliability and durability of the snap-fit ​​assembly 8 connection.

[0054] In this embodiment, the vehicle achieves effective sealing of the front compartment through the air guide plate structure. The contact seal between the sponge strips around the air guide plate and the body sheet metal effectively blocks all gaps in the opening area of ​​the front compartment, preventing airflow leakage from non-air guide channels and ensuring the airflow guiding effect. A sponge strip is provided at the edge of the opening corresponding to the engine hood latch bracket position on the air guide plate. The sponge strip fits snugly against the latch bracket, achieving a seal at the opening and preventing airflow leakage. Similarly, a sponge strip is provided at the edge of the opening corresponding to the latch cable bracket position on the air guide plate. The sponge strip fits snugly against the latch cable bracket, achieving a seal at that location.

[0055] Through the combined effect of the above-mentioned multiple sealing measures, the sealing performance of the vehicle's front compartment in this embodiment is significantly improved, the heat dissipation efficiency is effectively improved, and the overall vehicle thermal management performance is optimized.

[0056] Example 3 In a typical embodiment of the present invention, an installation method for an air guide plate structure is provided. This installation method utilizes the air guide plate structure described in Embodiment 1 above to solve the problems of large-sized air guide plates obstructing the assembly view and cutting workers' arms at the front edge when installing the front bumper.

[0057] In the traditional assembly process of large / mid-size SUVs, the air deflector is usually installed before the front bumper; that is, the air deflector is fixed to the front compartment of the vehicle first, and then the front bumper is installed. However, for larger SUV models, the X-axis unfolded length of the air deflector can reach approximately 367.8mm, and the front edge of the front body 1 of the air deflector extends to the front of the front bumper mounting area, leading to the following two main problems: 1. Obstructing the installation view: After the front body 1 of the air guide plate is unfolded, its front edge is located in front of the front bumper installation area, which obstructs the worker's view of the front bumper installation fixing points, making it difficult for the worker to accurately find the fixing holes of the front bumper, affecting assembly efficiency and assembly quality.

[0058] Second, cutting workers' arms. When installing the front bumper, workers need to push the front bumper from front to back into place. During the pushing process, the worker's arm needs to go past the front edge of the front body 1 of the air guide plate. Moreover, the contact force between the worker's arm and the front edge of the air guide plate is relatively large when pushing the front bumper, which can easily cause discomfort or even cuts to the worker's arm, affecting the worker's operational safety and comfort.

[0059] The installation method of this embodiment utilizes the characteristic that the front body 1 of the air guide plate can be flipped relative to the rear body 2 of the air guide plate, so that the front body 1 of the air guide plate is in a drooping state before the front bumper is installed, thus fundamentally solving the above two problems.

[0060] The specific steps for installation are as follows: Step 1: Transfer and preparation of the air guide plate.

[0061] The air guide plate is removed from the storage area and transported to the assembly station. During transportation, the front body 1 of the air guide plate can be flipped and folded relative to the rear body 2, so that the air guide plate is in a folded state. The space occupied in the X direction is shortened from about 367.8mm to about 240mm, with a compression of about 34.7%. This effectively reduces the space occupied by the air guide plate during transportation and handling, reduces the difficulty of handling, and avoids collision and interference between the air guide plate and surrounding parts.

[0062] During the assembly station preparation stage, confirm that the front ear plate 7 and the rear ear plate 6 between the front body 1 and the rear body 2 of the air guide plate are in the corresponding positions, the buckle assembly 8 is in the uninstalled state, and the front body 1 of the air guide plate is in the state where it can be freely flipped.

[0063] Step 2: Positioning and fixing the main body behind the air guide plate.

[0064] The air guide plate is moved as a whole to the installation position in the front compartment of the vehicle. The positioning holes 10 on the upright plate 9 of the rear body 2 of the air guide plate are used to engage with the corresponding positioning pins in the front compartment of the vehicle to achieve the initial positioning of the air guide plate. After the positioning pins are inserted into the positioning holes 10, the position of the air guide plate in the width direction (Y direction) and height direction (Z direction) of the vehicle is precisely constrained, preventing the air guide plate from shifting before the fixing bolts are tightened.

[0065] After initial positioning, the fixing bolts are inserted through the fixing holes 11 to reliably fix the rear body 2 of the air guide plate to the front compartment of the vehicle. The fixing bolts are tightened to the specified torque to ensure that the connection strength between the rear body 2 of the air guide plate and the vehicle body meets the reliability requirements of the whole vehicle. At this time, the clip assembly 8 is not installed between the front body 1 of the air guide plate and the rear ear plate 6. Under the action of gravity, the front body 1 of the air guide plate hangs naturally downward relative to the rear body 2 of the air guide plate and is in a drooping state.

[0066] Step 3: Confirm the drooping status of the front body of the air guide plate.

[0067] After the rear body 2 of the air guide plate is fixed, ensure that the front body 1 of the air guide plate is in a natural hanging state. In the hanging state, the front body 1 of the air guide plate flips downward around the connecting part 3, and the lower edge of the front body 1 of the air guide plate is located above the installation position of the front bumper. The front body 1 of the air guide plate does not obstruct the installation view of the front bumper.

[0068] At the same time, it was confirmed that the front edge of the front body 1 of the air guide plate is far away from the normal operating area of ​​the worker's arm when it is hanging down, so that the worker's arm will not come into contact with the front edge of the front body 1 of the air guide plate when installing the front bumper. Since the width of the front body 1 of the air guide plate is less than the height difference between the air guide plate and the front bumper after installation, the lower edge of the front body 1 of the air guide plate will not be lower than the installation position of the lower edge of the front bumper after it is hanging down, and there will be no interference with the front bumper.

[0069] Step 4: Install and secure the front bumper.

[0070] With the front body 1 of the air deflector in a drooping state, the worker moves the front bumper from the front of the vehicle to the installation position and pushes it backward to the corresponding installation position on the vehicle body. Because the front body 1 of the air deflector is in a drooping state, the worker can clearly see each installation fixing point of the front bumper during the process of pushing the front bumper, and the field of vision is unobstructed, which facilitates accurate alignment.

[0071] When the worker's arm pushes the front bumper, since the front body 1 of the air guide plate has been flipped downwards, its front edge is not in the operating path of the worker's arm. The worker's arm will not come into contact with the front edge of the front body 1 of the air guide plate, which effectively avoids the risk of the arm being cut and improves the safety and comfort of the assembly operation.

[0072] After the front bumper is pushed into place, install the various fasteners of the front bumper, including fixing bolts and clips, in the prescribed assembly sequence to reliably fix the front bumper to the vehicle body.

[0073] Step 5: Flip and lock the front body of the air guide plate.

[0074] After the front bumper is installed and fixed, the worker flips the front body 1 of the air guide plate upward from its drooping state, making it flush with the rear body 2 of the air guide plate, with the top surface of the front body 1 and the top surface of the rear body 2 on the same plane. During the flipping process, the connecting part 3 bends and deforms, providing a hinge function for the flipping of the front body 1 of the air guide plate. At the same time, the elastic restoring force of the connecting part 3 provides a certain holding force for the front body 1 of the air guide plate, preventing it from drooping again due to vibration or accidental contact after being flipped into place.

[0075] After the front body 1 of the air guide plate is flipped to be flush with the rear body 2 of the air guide plate, the front ear plate 7 on the front body 1 and the rear ear plate 6 on the rear body 2 of the air guide plate are aligned. The worker inserts the buckle assembly 8 through the corresponding front ear plate 7 and rear ear plate 6 in sequence, and uses the locking structure of the buckle assembly 8 to reliably lock the front ear plate 7 and rear ear plate 6, thereby achieving relative fixation of the front body 1 and the rear body 2 of the air guide plate.

[0076] After the snap-fit ​​assembly 8 is installed, check that all snap-fit ​​assemblies 8 are fully locked in place, and confirm that there is no relative displacement between the front body 1 and the rear body 2 of the air guide plate, and that the air guide plate is in a fully extended and flush locked state. At this point, the installation of the air guide plate structure is complete.

[0077] The installation method in this embodiment utilizes the characteristic that the front body 1 of the air guide plate can be flipped relative to the rear body 2 of the air guide plate. Before installing the front bumper, the front body 1 of the air guide plate is in a drooping state, effectively solving the problem of large-sized air guide plates obstructing the installation view of the front bumper. After the front body 1 of the air guide plate is drooping, the length occupied by the air guide plate in the X direction is shortened from approximately 367.8 mm to approximately 240 mm, a reduction of approximately 34.7%. Workers can clearly see all the mounting points of the front bumper, significantly improving assembly efficiency and quality. It effectively avoids the problem of workers' arms being cut by the front edge of the air guide plate. After the front body 1 of the air guide plate is drooping, its front edge is far away from the worker's arm operating area, so the worker's arm will not come into contact with the front edge of the air guide plate when pushing the front bumper, significantly improving operational safety and comfort.

[0078] The entire installation process requires no additional special tooling or auxiliary equipment. The above effect can be achieved solely by the hinge flipping structure of the air guide plate itself, without increasing the cost of additional tooling and ensuring the consistency and repeatability of the assembly process.

[0079] When folded, the air guide plate facilitates storage and transportation, reducing logistics costs. At the same time, within the limited operating space of the assembly station, the folded air guide plate is less likely to interfere with surrounding parts, ensuring the smoothness of the assembly process.

[0080] The installation method described in this embodiment is not only applicable to the specific large / medium-sized SUV models mentioned above, but can also be extended to other models that require the front bumper to be installed after the air deflector, especially models with large air deflectors and limited front bumper installation space. By utilizing the core idea of ​​this installation method—that the front body of the air deflector flips down to provide operating space for the front bumper installation—and applying it to the air deflector design of different models, assembly difficulties can be solved from the product design stage, preventing assembly problems from being passed on to other workstations on the production line, effectively improving product design capabilities and production efficiency.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
