Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.
[0031] In the description of the present disclosure, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly specified.
[0032] From Figure 1 As can be seen, the air deflector 2 of the radiator of the vehicle engine is connected to the grille 1 of the vehicle, the edges of the air deflector 2 are each provided with a sealing device 3, and the air deflector 2 is sealingly connected with the grille 1 through the sealing device 3 to ensure good sealing between the grille 1 and the radiator, thereby reducing the air leakage rate.
[0033] It should be noted here that the vehicle grille 1 is located at the front side 13 of the vehicle, and the air deflector 2 is located at the rear side 14 of the grille 1, as shown in Figure 2 The sealing device 3 for the air deflector 2 of the utility model includes a connecting portion 31 of the air deflector 2 and a sealing strip 4 mounted on the connecting portion 31, and the connecting portion 31 is arranged at the front side edge of the air deflector 2.
[0034] In this embodiment, the connecting portion 31 is integrally formed with other parts of the air deflector 2, which can be injection molded by a single color injection molding machine, facilitating production. The connecting portion 31 and the air deflector 2 are hard rubber parts, which can be made of PP-GF30 (glass fiber reinforced polypropylene-glass fiber) material. The PP-GF30 material has good heat resistance, and the PP-GF30 material can maintain good performance stability, meeting the requirements of long-term use. Moreover, the PP-GF30 material has a relatively low cost, which can reduce the production cost of manufacturing. In other embodiments, the connecting portion 31 can be separately provided and fixed to the front side edge of the air deflector 2.
[0035] Specifically, from Figure 2 It can be clearly seen that the air deflector 2 has four panels 21 connected to form a rectangular frame as shown, and each panel 21 is provided with a connecting portion 31 (as Figure 3 shown) on the edge of the front side 13, that is, the connecting portion 31 is arranged along the edge of the front side 13 of the panel.
[0036] It should be noted that the air deflector 2 and the sealing device 3 have a first surface 11 and a second surface 12 opposite to each other. The first surface 11 of the connecting portion 31 is a flat surface, and the rear end of the first surface 11 extends a flange 35.
[0037] The connecting portion 31 is provided with a first protruding strip 32 and a second protruding strip 33 protruding from the second surface 12, the first protruding strip 32 is arranged on the front side of the connecting portion 31, the second protruding strip 33 is arranged close to the rear side of the connecting portion 31, and a first clamping groove 34 is formed between the first protruding strip 32 and the second protruding strip 33. The second protruding strip 33 and the flange 35 form a fixing space 36 on the rear side of the connecting portion 31.
[0038] As Figure 3 shown, the second protruding strip 33 is longer than the first protruding strip 32, the front edge of the air deflector 2 is clamped and fixed in the fixing space 36, the second protruding strip 33 is tightly fixed to the front side of the front edge of the air deflector 2, and the flange 35 is tightly fixed to the first surface 11 of the front edge of the air deflector 2, so that the connecting portion 31 is fixed to the front edge of the air deflector 2. The fixing mode can be welding, bonding, etc.
[0039] In other embodiments, the connecting portion 31 can be installed at other positions of the air deflector 2, that is, the flange 35 can be tightly fixed to the second surface 12 of the front edge of the air deflector 2, and can be set according to actual needs.
[0040] From Figure 3 the embodiments, it can be seen that the corners of the connecting portion 31 except the fixing space 36 are all rounded corners, and the corners of the fixing space 36 can have unlimited shapes, such as rounded corners, right angles, chamfered corners, etc., as long as they can adapt to the shape of the front edge of the air deflector 2.
[0041] From Figure 4 it can be seen that the sealing strip 4 has a sealing portion 5 located on the front side 13 and a clamping portion 41 located on the rear side 14.
[0042] As shown, the clamping portion 41 has a third clamping groove 44 close to the second surface 12 and a fourth clamping groove 45 close to the first surface 11. The rear side 14 edge of the third clamping groove 44 protrudes a third protruding strip 42 towards the first surface 11, and the rear side 14 edge of the fourth clamping groove 44 protrudes a fourth protruding strip 43 towards the second surface 12.
[0043] The third slot 44, the fourth slot 45, the third protrusion 42, and the fourth protrusion 43 form the snap-fit space of the connecting part 31, such as Figure 5 As shown, the connecting part 31 fits perfectly into the snap-fit space of the sealing strip 4.
[0044] Specifically, in combination Figure 3 , Figure 4 as well as Figure 5 As can be seen, the snap-fit portion 41 of the sealing strip 4 wraps around and fits the outer periphery of the connecting portion 31. The chamfer design of the connecting portion 31 allows the connecting portion 31 to fit the sealing strip 4 more closely and does not wear the sealing strip 4, thereby extending the service life of the sealing strip 4.
[0045] like Figure 5 As shown, in the direction of the front side 13 and the rear side 14 of the sealing strip 4, the sealing strip 4 wraps around the front end of the connecting part 31, and the fourth protrusion 43 of the sealing strip 4 abuts against the rear side 14 edge of the flange 35 of the connecting part 31, thereby fixing the position of the sealing strip 4 from the front and rear sides of the sealing strip 4.
[0046] In the direction of the first surface 11 and the second surface 12 of the sealing strip 4, that is, in the direction of the top and bottom of the sealing strip 4, the fourth groove 45 of the sealing strip 4 wraps around the first surface 11 and the flange 35 of the connecting part 31 from the top, the third groove 44 of the sealing strip 4 wraps around the first protrusion 32 of the connecting part 31 from the bottom, and the third protrusion 42 of the sealing strip 4 is embedded in the first groove 34 of the connecting part 31 from the bottom, thereby fixing the position of the sealing strip 4 from the top and bottom of the sealing strip 4.
[0047] Thus, the sealing strip 4 is fixed in four directions—the first surface 11, the second surface 12, the front side 13, and the rear side 14—by engaging with the connecting part 31. During installation, the sealing strip 4 can enter from both ends of the connecting part 31, slide along the connecting part 31, and bend according to the shape of the connecting part 31 to fit the connecting part 31, thereby achieving a seal at the edge of the air guide plate 2.
[0048] from Figure 4 It can also be seen that the sealing part 5 of the sealing strip 4 includes an elastic flange 51. In Figure 4 In one embodiment, the elastic flange 51 extends from the second surface 12 of the snap-fit portion 41 to the front side 13 and then extends obliquely towards the first surface 11, forming a concave deformation space 52 between the first surface 11 of the sealing strip 4 and the connecting portion 31.
[0049] In other embodiments, the position and orientation of the elastic flange 51 can be changed, that is, the elastic flange extends from the first surface 11 of the snap-fit portion 41 to the front side 13 and then to the second surface 12, forming a concave deformation space 52 between the second surface 12 of the sealing strip 4 and the connecting portion 31.
[0050] The air guide plate 2 is sealed to the grille 1 (e.g.) Figure 1 When shown), as Figure 6 As shown, the elastic flange 51 of the sealing portion 5 of the sealing strip 4 of the sealing device 3 abuts against the grille 1, and the elastic flange 51 fits the grille 1. The snap-fit portion 41 of the sealing strip 4 snaps into the connecting portion 31 of the air guide plate 2 (as shown). Figure 2 As shown, the elastic flange 51 is squeezed by the grille 1 and the air guide plate 2 on both sides, causing it to deform and compress the deformation space 52. This makes the elastic flange 51 fit the shape of the grille 1 more tightly, and makes the air guide plate 2 and the grille 1 more tightly sealed, thus playing a sealing role.
[0051] exist Figure 6 In one embodiment, the connection between the grille 1 and the sealing strip 4 is a plane. In other embodiments, the connection between the grille 1 and the sealing strip 4 can also be other shapes. By squeezing the elastic flange 51 of the sealing strip 4, the elastic flange 51 is made to fit the shape of the connection between the grille 1 and the air guide plate 2 more closely.
[0052] The sealing strip 4 is a soft rubber component, which can be made of TPV (thermoplastic vulcanizate) material. TPV material has high elasticity, allowing the elastic flange 51 to better fit the connection of the grille 1. Furthermore, TPV material has excellent wear resistance, thereby increasing the service life of the sealing device 3. The sealing strip 4 can also be produced by single-color injection molding, and its length can be cut according to actual needs, facilitating replacement.
[0053] The sealing device 3 of this utility model has a connecting part 31 and a sealing strip 4. The connecting part 31 is located on the front edge of the air guide plate. The sealing strip 4 is engaged with the connecting part 31 by a snap-fit method to form a solid whole, achieving excellent sealing effect. The sealing device has a simple structure and fewer restrictions on the shape of the grille and its peripheral fit. Various close-fitting sealing shapes can be formed by compressing the sealing strip 4. This sealing device can be applied to various types of grilles and air guide plates.
[0054] The connecting part 31 of the sealing device 3 of this utility model can be integrally formed with the air guide plate 2, and can be injection molded by a single-color injection molding machine, which facilitates production and reduces production costs. The sealing strip 4 is set separately and can be cut and assembled onto the air guide plates of different vehicle models according to different needs.
[0055] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
