[0030] Please also read Figures 1 to 8 The bumper structure, bumper installation assembly and vehicle provided by the utility model are now described. The bumper structure includes a bumper body 1, and first clamping holes 2 are respectively provided on both sides of the bumper body 1, and the first clamping holes 2 are clamped with the first buckle 61 of the lower decorative plate 6;

[0031] The lower edge of the first clamping hole 2 is connected with a first pressing tongue 21 , which extends obliquely upward toward the center axis of the vehicle body, and the extended end of the first pressing tongue 21 presses against the bottom of the first buckle 61 .

[0032] Compared with the prior art, the bumper structure provided in the present embodiment is a bumper structure that realizes snap-fitting with the first snap 61 on the lower decorative panel 6 by setting the first snap hole 2 on the bumper body 1, and utilizes the first pressing tongue 21 connected to the lower edge of the second snap hole 4 to press against the bottom of the first snap 61 to prevent the first snap 61 from escaping from the first snap hole 2, which not only facilitates the snap-fitting between the first snap 61 and the first snap hole 2, but also ensures a reliable connection effect, effectively improves the installation efficiency, ensures the reliability of the connection between the bumper body 1 and the lower decorative panel 6, and helps to reduce the gap surface difference between the two.

[0033] In this embodiment, the first clamping hole 2 is simple and convenient to set, which effectively avoids the tediousness caused by opening a special-shaped hole in the component, and helps to reduce the component processing cost. The first pressing tongue 21 is set to effectively limit the first buckle 61 to the upper area of ​​the first clamping hole 2, avoiding the first buckle 61 from falling out, and improving the reliability of the clamping fit.

[0034] Specifically, the first pressing tongue 21 can be set as an ordinary plate-like component, and adopts a structure that extends obliquely toward the inner side of the vehicle body. The simple plate-like structure can realize the pressing effect on the bottom surface of the first buckle 61, thereby ensuring the stable and reliable position of the first buckle 61 in the first clamping hole 2, facilitating the structural forming of the first pressing tongue 21, and also facilitating ensuring the structural strength of the first pressing tongue 21, effectively avoiding the loosening of the first pressing tongue 21, and improving the reliability of the connection between the two sides of the bumper and the lower decorative panel 6.

[0035] The above structure not only simplifies the complexity of the first pressing tongue 21 , but also simplifies the overall structure of the mold for molding the bumper body 1 , which helps to reduce the consumption cost of the mold.

[0036] In some possible implementations, the above-mentioned characteristic bumper body 1 is adopted as follows Figures 4 to 5 , as shown in the structure. Figures 4 to 5 The side of the bumper body 1 is provided with a first clearance cavity 3 which is concavely arranged toward the central axis side of the vehicle body. The first clearance cavity 3 has a first guide wall 31 and a first upright wall 32. The first guide wall 31 extends obliquely from bottom to top toward the central axis side of the vehicle body. The first upright wall 32 is connected to the upper edge of the first guide wall 31. The first clamping hole 2 extends upward from the first guide wall 31 to the first upright wall 32. The extending end of the first pressing tongue 21 protrudes upward from the upper edge of the first guide wall 31.

[0037] In this embodiment, by setting the first clearance cavity 3 on the side of the bumper body 1, the portion of the upper edge of the lower decorative plate 6 provided with the first buckle 61 is effectively avoided, so that the upper edge of the lower decorative plate 6 can be effectively limited in the first clearance cavity 3, and the first buckle 61 is used to achieve a reliable connection with the first clamping hole 2, further improving the reliability of installation. At the same time, the setting of the above-mentioned first clearance cavity 3 can also form a smooth transition between the lower decorative plate 6 and the side of the bumper body 1 after the lower decorative plate 6 is installed, ensuring the external aesthetics of the structure.

[0038] The side wall of the first clearance cavity 3 is in the form of a combination of a first guide wall 31 and a first upright wall 32, so as to provide guidance for the insertion of the first clip 61. More importantly, the above-mentioned combination can make the extended end of the first pressing tongue 21 protrude from the upper edge of the first clamping hole 2 on the inner side of the vehicle body, so that the small swing amplitude of the first pressing tongue 21 reduces the difficulty of the insertion of the first clip 61, helps to improve the clamping efficiency of the first clip 61, and ensures that the first clip 61 is locked in position under the action of the first pressing tongue 21 after being inserted, so as to reduce the gap surface difference between the lower decorative panel 6 and the bumper body 1.

[0039] In some possible implementations, the above-mentioned characteristic bumper body 1 is adopted as follows Figure 1 , Figure 3 , Figure 4 and Figure 6 , as shown in the structure. Figure 1 , Figure 3 , Figure 4 and Figure 6 The bumper body 1 is provided with a plurality of second clamping holes 4 that penetrate from front to back. The second clamping holes 4 are used to clamp with the second buckle 62 of the lower decorative panel 6. The lower edge of the second clamping hole 4 is connected with a second pressing tongue 41. The second pressing tongue 41 extends obliquely upward toward the rear side of the vehicle body, and the extended end of the second pressing tongue 41 presses against the bottom of the second buckle 62.

[0040] In this embodiment, the middle part of the lower decorative panel 6 is clipped into the second clip hole 4 through the second clip 62, so that the middle part of the lower decorative panel 6 on both sides can be connected to the bumper body 1 at multiple points in the left and right directions of the vehicle body, ensuring the reliability of the connection between the two.

[0041] Specifically, both sides of the lower decorative plate 6 are respectively inclined outward and rearward, and combined with the middle area of ​​the lower decorative plate 6, the entire lower decorative plate 6 forms a structure covering the front and both sides of the bumper body 1. When the lower decorative plate 6 is installed to the lower front side of the bumper body 1, the second buckle 62 is aligned with the second buckle hole 4, and the lower decorative plate 6 is pushed backward to achieve the buckling of the second buckle 62 with the first buckle hole 2.

[0042] Afterwards, the two sides of the lower decorative panel 6 are opened outward to provide space for the first clip 61 to be inserted into the first clip hole 2. At the same time, the first clip 61 and the first clip hole 2 are made to correspond to each other, and the two sides of the lower decorative panel 6 are loosened. The first clip 61 is inserted into the first clip hole 2 toward the inner side of the vehicle body to achieve the snap-fitting of the first clip hole 2 and the first clip 61, so that the lower decorative panel 6 is reliably connected to the bumper body 1.

[0043] On the basis of the above structure, a second make way cavity 5 is provided on the front side wall of the bumper body 1 and is recessed inside the vehicle body. The second make way cavity 5 has a second guide wall 51 and a second upright wall 52. The second guide wall 51 extends obliquely from bottom to top toward the rear side of the vehicle body. The second upright wall 52 is connected to the upper edge of the second guide wall 51. The second clamping hole 4 extends from the second guide wall 51 to the second upright wall 52. The second pressing tongue 41 extends upward to protrude from the upper edge of the second guide wall 51.

[0044] The structure of the second clearance cavity 5 is the same as that of the first clearance cavity 3, and will not be described in detail here. The second clearance cavity 5 can also be provided to improve the clamping efficiency of the second buckle 62, ensuring that the second buckle 62 is locked in position under the action of the second pressing tongue 41 after being clamped, so as to reduce the gap surface difference between the lower decorative plate 6 and the bumper body 1.

[0045] In some possible implementations, the above-mentioned characteristic bumper body 1 is adopted as follows Figure 1 , Figure 3 and Figure 4 , as shown in the structure. Figure 1 , Figure 3 and Figure 4 A plurality of main weight-reducing holes 11 are provided on the front side wall of the bumper body 1. The main weight-reducing holes 11 are located below the second clamping hole 4, and the main weight-reducing holes 11 are arranged at intervals along the left-right direction.

[0046] In this embodiment, the main weight-reducing holes 11 are located on a large area on the front side of the bumper body 1. The main weight-reducing holes 11 are evenly distributed in the left and right directions, which can achieve uniform weight reduction, meet lightweight design requirements, and reduce material consumption.

[0047] Specifically, the main weight-reducing holes 11 can be in different shapes such as rectangle, circle or polygon, and the distance between two adjacent weight-reducing holes should be as equal as possible, which is convenient for processing and manufacturing the mold, and also convenient for the molding of the bumper body 1, ensuring the weight-reducing effect while avoiding strength attenuation caused by excessively large holes in local positions.

[0048] In some embodiments, the side of the bumper body 1 is further provided with a side weight-reducing hole 12, and the side weight-reducing hole 12 is located below the first clamping hole 2. By providing the side weight-reducing hole 12, the side area of ​​the bumper body 1 is reduced in weight, so that all parts of the entire bumper body 1 can be evenly reduced in weight. The side weight-reducing hole 12 can be arranged in shape according to the actual design position, and can be designed in different shapes such as triangle, rectangle, trapezoid or circle.

[0049] In some embodiments, the main lightening holes 11 and the side lightening holes 12 may be formed as follows: Figure 1 and Figure 3 , as shown in the structure. Figure 1 and Figure 3 The edges of the main weight-reducing hole 11 and the side weight-reducing hole 12 are respectively provided with reinforcing flanges 13 bent toward the inner side of the vehicle body, and the reinforcing flanges 13 are arranged perpendicular to the inner wall of the bumper body 1 .

[0050] In this embodiment, the reinforcing flap is arranged along the edge of the main weight-reducing hole 11 or the side weight-reducing hole 12 and is closed in a ring shape. The structure of the part of the bumper body 1 where the main weight-reducing hole 11 or the side weight-reducing hole 12 is provided can be reinforced. With minimal increase in material consumption, the overall strength of the structure is effectively improved, and a good reinforcement effect is achieved.

[0051] Based on the same inventive concept, an embodiment of the present application also provides a bumper mounting assembly, which includes a lower decorative panel 6 and a bumper structure. The lower decorative panel 6 is provided with a first clip 61, which is clipped into the first clip hole 2 of the bumper body 1.

[0052] In some possible implementations, the first buckle 61 is as follows: Figures 1 to 8 , as shown in the structure. Figures 1 to 8 The first buckle 61 extends horizontally toward the inside of the vehicle body, and the width of the extended end of the first buckle 61 in the front-to-rear direction gradually decreases. The extended end of the first buckle 61 is provided with an upwardly protruding snap-on portion 63, which can be snap-on to the inner side of the upper edge of the first snap-on hole 2.

[0053] The above-mentioned bumper assembly is configured with a first clip hole 2 on the bumper body 1 to achieve snap-fitting with the first clip 61 on the lower decorative panel 6, and utilizes a first pressing tongue 21 connected to the lower edge of the second clip hole 4 to press against the bottom of the first clip 61 to prevent the first clip 61 from escaping from the first clip hole 2, which not only facilitates the snap-fitting between the first clip 61 and the first clip hole 2, but also ensures a reliable connection effect, effectively improves the installation efficiency, ensures the reliability of the connection between the bumper body 1 and the lower decorative panel 6, and helps to reduce the gap surface difference between the two.

[0054] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, the vehicle comprising a bumper installation assembly. The bumper assembly on the vehicle is easy to install and has good installation reliability.
