Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts, and in particular to a radiator air guide structure and a vehicle having the same. Background Technology
[0002] Automotive radiators are used not only in gasoline-powered vehicles but also in new energy pure electric vehicles and hybrid electric vehicles. Radiator air deflectors are an indispensable component for improving radiator performance and reducing wind resistance. Currently, there are two types of radiator air deflectors on the market. One type uses PP material with ordinary injection molding, with sealing foam glued to the edges to seal with surrounding components such as bumpers and front-end modules. This method not only requires an additional foam installation step but also suffers from unreliable foam adhesion, frequently resulting in detachment and loss of sealing, thus reducing or eliminating the airflow guiding effect of the radiator air deflector. The other type uses PP+PVC material with a two-color injection molding process. The soft PVC absorbs tolerances and seals with surrounding components such as bumpers to prevent air loss and avoid increased wind resistance. The two-color injection molding process for PP+PVC material offers better reliability and sealing, but the mold cost and unit cost are higher. Utility Model Content
[0003] In view of this, the present invention provides a radiator air guide plate structure and a vehicle having the same, which not only ensures the sealing of the front edge of the air guide plate body and the front bumper air intake grille area, but also has a simple process and low production cost.
[0004] This utility model provides a radiator air guide plate structure, including an air guide plate body, a tongue, and a weakening groove. The air guide plate body is disposed on both sides of the radiator. The tongue is connected to one end of the air guide plate body near the air intake grille. The weakening groove is disposed on the air guide plate body and is disposed adjacent to the tongue. The weakening groove and the tongue are in contact with the inner walls of both sides of the air intake grille.
[0005] Furthermore, multiple tongues are provided, and the multiple tongues are spaced apart along the length direction of the air guide plate body, with a first gap formed between two adjacent tongues.
[0006] Furthermore, the weakening groove is arranged parallel to the tongue, and the weakening groove includes a first weakening groove and a second weakening groove, which are arranged on the inner and outer sides of the air guide plate body.
[0007] Furthermore, the opening of the first weakening groove faces the interior of the air guide plate body, the opening of the second weakening groove faces the exterior of the air guide plate body, and the bottoms of both the first and second weakening grooves are recessed towards the air guide plate body.
[0008] Furthermore, the weakening grooves are provided in multiple ways, and the multiple weakening grooves are spaced apart along the length direction of the air guide plate body. A second gap is formed between two adjacent weakening grooves, and the second gap is connected to the first gap.
[0009] Furthermore, the second gap is formed by two opposing first arc-shaped structures and second arc-shaped structures, with the opening of the first arc-shaped structure facing the second arc-shaped structure and the opening of the second arc-shaped structure facing the first arc-shaped structure.
[0010] Furthermore, the distance between the weakening groove and the tongue is 0-2mm.
[0011] Furthermore, the width of the tongue is 8-12mm, the length is 28-32mm, and the width of the first gap is 2.0-3.0mm.
[0012] Furthermore, the width of both the first weakening groove and the second weakening groove is 3-5mm, and the distance between the bottom of the first weakening groove and the bottom of the second weakening groove is 0.4-0.8mm.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0021] In the description of this utility model, it should be noted that the orientation or positional relationship indicated in this description is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the parts or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] Please refer to the following: Figure 1 and Figure 2 The present invention provides a radiator air guide plate structure, including an air guide plate body 10, a tongue 20, and a weakening groove 30. The air guide plate body 10 is disposed on both sides of the radiator. The tongue 20 is connected to one end of the air guide plate body 10 near the air intake grille, that is, the tongue 20 is connected to the front edge of the air guide plate body 10. The weakening groove 30 is disposed on the air guide plate body 10 and is adjacent to the tongue 20. The weakening groove 30 and the tongue 20 are fitted with the inner walls of both sides of the air intake grille to form a sealed area, which effectively guides the air entering through the air intake grille and delivers it to the radiator, thereby improving the heat dissipation efficiency of the radiator. This invention, by setting a tongue 20 and a weakening groove 30 on the front edge of the air guide plate body 10, which fits against the inner walls of both sides of the air intake grille, can ensure the sealing of the front edge of the air guide plate body 10 with the air intake grille area of the front bumper. Compared with the prior art, there is no need to add sealing foam, the sealing performance is stable, and the production cost is low. In addition, the setting of the weakening groove 30 enables the front edge of the air guide plate body 10 to have a deformation function, which can absorb the interference, as well as the tolerance of parts and assembly tolerances, avoiding the difficulty of assembly caused by interference from hard materials, or the front bumper being blocked.
[0023] Please refer to the following: Figure 3Multiple tongues 20 are provided, spaced apart along the length of the air guide plate body 10, which is equivalent to the Z-direction of the vehicle. Each tongue 20 is made of ordinary PP material and is injection molded to the front end of the air guide plate body 10, resulting in a simple and low-cost process. It should be noted that the size and shape of the front edge of the air guide plate body 10 can be determined based on the layout of the vehicle's front compartment and the shape of the inner wall of the front bumper radiator grille; similarly, the size and shape of the tongues 20 can be determined based on the size and shape of the front edge of the air guide plate body 10, facilitating interference between the tongues 20 and the inner wall of the air intake grille, ensuring the sealing between the front edge of the air guide plate body 10 and the front bumper air intake grille area. The width of each tongue 20 ranges from 8-12mm, preferably 10mm, and the length of each tongue 20 ranges from 28-32mm, preferably 30mm.
[0024] Furthermore, since multiple tongues 20 are spaced apart along the length of the air guide plate body 10, a first gap 40 is formed between adjacent tongues 20. Also, because the weakening groove 30 enables the front end of the air guide plate body 10 to deform, and because the degree of deformation varies in different areas of the front end of the air guide plate body 10, multiple tongues 20 are provided, spaced apart, to prevent mutual pulling between different areas of the front end of the air guide plate body 10 during deformation. This first gap 40 allows the tongues 20 adjacent to a certain area of the front end of the air guide plate body 10 to break when that area deforms. This facilitates the tongues 20's installation with the inner wall of the air intake grille, allowing them to conform well to the shape of the areas on both sides of the inner wall of the air intake grille, improving the sealing at the contact area. The width of the first gap 40 is between 2.0-3.0 mm, preferably 2.5 mm.
[0025] Please refer to it again. Figure 1 and Figure 2 , Figure 1 This is a front view of the air guide plate structure on one of the two sides of the radiator, that is, a view of the air guide plate structure from the outside in. Figure 2 This is an inside-out view of the air guide structure. The weakening groove 30 is arranged parallel to the tongue 20, and the distance between the weakening groove 30 and the tongue 20 is 0-2mm, preferably 1mm. The shape and position of the weakening groove 30 can ensure that the tongue 20 can deform well when subjected to interference, avoiding assembly difficulties caused by interference from hard materials, or the tongue 20 hitting the front bumper.
[0026] To further improve the accuracy of tongue 20 deformation, the weakening groove 30 is configured as a first weakening groove 31 and a second weakening groove 32. The first weakening groove 31 and the second weakening groove 32 are respectively located on the inner and outer sides of the air guide plate body 10 and are arranged symmetrically. Specifically, the opening of the first weakening groove 31 faces the inside of the air guide plate body 10, and the opening of the second weakening groove 32 faces the outside of the air guide plate body 10. The bottom of the first weakening groove 31 and the second weakening groove 32 are both recessed in the direction towards the air guide plate body 10, so that the tongue 20 can deform along the weakening groove 30 to the inner and outer sides of the air guide plate body 10. The width of the first weakening groove 31 is between 3-5 mm, preferably 4 mm, and the width of the second weakening groove 32 is also between 3-5 mm, preferably 4 mm. The distance between the bottom of the first weakening groove 31 and the bottom of the second weakening groove 32 is 0.4-0.8 mm, preferably 0.6 mm. That is, the thickness of the bottom material of the weakening groove 30 is preferably 0.6 mm.
[0027] Similarly, the weakening grooves 30 are arranged similarly to the tongue 20. Multiple weakening grooves 30 are also provided, spaced apart along the length of the air guide plate body 10. A second gap 50 is formed between two adjacent weakening grooves 30, and the second gap 50 communicates with the first gap 40. The function of the second gap 50 is the same as that of the first gap 40: to prevent different areas at the front end of the air guide plate body 10 from pulling on each other during deformation. This allows the tongue 20 adjacent to a certain area at the front end of the air guide plate body 10 to break apart when deformed, facilitating the tongue 20's installation with the inner wall of the air intake grille and ensuring it conforms well to the shape of the areas on both sides of the inner wall.
[0028] Furthermore, the second gap 50 is formed by two opposing first arc-shaped structures 51 and second arc-shaped structures 52. The opening of the first arc-shaped structure 51 faces the second arc-shaped structure 52, and the opening of the second arc-shaped structure 52 faces the first arc-shaped structure 51. Due to the arrangement of the arc-shaped structures 51, the length of each weakening groove 30 is shorter than the length of the corresponding tongue 20, which is more conducive to the deformation of the tongue 20.
[0029] As described above, the radiator air guide plate structure provided by this utility model, by setting tongues 20 and weakening grooves 30 on the front edge of the air guide plate body 10, can closely fit with the inner walls of both sides of the air intake grille, ensuring the sealing of the front edge of the air guide plate body 10 with the air intake grille area of the front bumper. Compared with the prior art, there is no need to add sealing foam, the sealing performance is stable, the material is ordinary PP material, injection molded, and the production cost is low. In addition, the setting of the weakening groove 30 enables the front edge of the air guide plate body 10 to have a deformation function, which can absorb the interference, as well as the tolerance of parts and assembly tolerances, avoiding the difficulty of assembly caused by interference of hard materials, or the front bumper being blocked. The setting of the first gap 40 and the second gap 50 can prevent the tongues 20 in different areas from being stretched during the deformation process.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
