The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0027] Please refer to Figs. 1 to 3 As shown, the present application provides a mounting structure of a front bumper 1 and a headlamp, which is used to connect the front bumper 1 to the headlamp. By connecting the front bumper 1 to the headlamp, the cantilever phenomenon of the front bumper can be solved, so that the front bumper 1 is better attached to the vehicle body, and the appearance and aerodynamic performance are improved.

[0028] In the embodiment of the present application, the mounting structure of the front bumper 1 and the headlamp includes a mounting bracket 2 and a headlamp bottom shell 3, and the front bumper 1 is connected to the headlamp bottom shell 3 through the mounting bracket 2. The headlamp bottom shell 3 is installed with the headlamp cover 4. The headlamp bottom shell 3 is provided with a glue groove 31, and at least one glue groove wall 32 forming the glue groove 31 includes a low-position supporting part 321 and a high-position extending part 322. The low-position supporting part 321 and the high-position extending part 322 are connected in a stepped manner, and an angle part 323 is formed between them. The mounting bracket 2 is supported on the low-position supporting part 321, and the angle part 323 can resist and limit the mounting bracket 2 when the mounting bracket 2 and the headlamp bottom shell 3 are installed. Wherein, the angle part 323 has an inner side surface 3231 and an outer side surface 3232, the inner side surface 3231 is a smooth curved surface connected between the low-position supporting part 321 and the high-position extending part 322, and the outer side surface 3232 is a cornered folding surface intersecting to form a corner.

[0029] The inner side surface 3231 is smooth, which does not affect the uniformity of the glue coating and the glue sealing performance of the headlamp bottom shell 3.

[0030] In some embodiments, the mounting bracket 2 is a separate component which is connected with the front bumper 1 and the headlamp bottom shell 3 respectively to realize the connection of the front bumper 1 and the headlamp bottom shell 3. In other embodiments, the mounting bracket 2 can also be integrated with the front bumper 1, that is, the mounting bracket 2 is a part of the structure of the front bumper 1.

[0031] Please refer to Fig. 2 and Fig. 3 In the embodiment, the glue groove 31 is surrounded by two glue groove walls 32. The two glue groove walls 32 are an upper glue groove wall and a lower glue groove wall, and the front bumper 1 is connected to the upper glue groove wall. The upper glue groove wall is provided with the low-position supporting part 321, the high-position extending part 322 and the corner part 323. The lower glue groove wall has a low-position wall 326 opposite to the low-position supporting part 321 and a high-position wall 327 extending from the high-position extending part 322, and the low-position wall 326 and the high-position wall 327 are connected by a smooth transition wall 328.

[0032] In the embodiment, the corner part 323 is formed on the upper glue groove wall because the upper glue groove wall needs to be matched with the mounting bracket 2 for installation. The lower glue groove wall is directly provided with the smooth transition wall 328, so that the structure of the lower glue groove wall is simple and the molding difficulty is reduced. Of course, in other embodiments, the front bumper 1 can be installed with the lower glue groove wall, or installed with the upper glue groove wall and the lower glue groove wall at the same time, and the lower glue groove wall can also be provided with the corner part 323.

[0033] In some embodiments, if the corner part 323 has the same structure design as the smooth transition wall 328, when the mounting bracket 2 is installed, a large gap will be formed between the mounting bracket 2 and the corner part 323, which affects the aerodynamic performance of the vehicle. In some embodiments, if the corner part 323 is directly made into a structure close to a right angle, although the problem of large assembly gap can be solved, but it will cause the corner in the glue groove 31 to be difficult to be filled with the adhesive, which affects the uniformity of the glue coating. The structure of the corner part 323 provided in the embodiment does not affect the uniformity of the glue coating and the glue sealing performance of the headlamp bottom shell 3.

[0034] Please continue to see Fig. 2 and Fig. 3 As shown in the figure, in the embodiment, the corner of the outer side surface 3232 of the corner part 323 includes a stop end surface 3234 perpendicular to the low support part 321, and a connecting surface 3235 connecting the stop end surface 3234 and the high extension part 322. The included angle between the stop end surface 3234 and the connecting surface 3235 is 80° to 100°. That is, the stop end surface 3234 and the connecting surface 3235 are arranged at a right angle or close to a right angle. The corner should be understood as at least two intersecting surfaces forming a clear corner structure, and the two intersecting surfaces forming the corner can be a plane or an arc surface, or other curved surfaces, which does not affect the overall corner structure. Of course, a small diameter fillet or bevel can be provided between the stop end surface 3234 and the connecting surface 3235 to prevent the sharp corner from scratching the assembler. It can be understood that the provision of the above-mentioned fillet or bevel does not mean that the stop end surface 3234 and the connecting surface 3235 do not form a corner structure that facilitates installation alignment and reduces assembly gap. In the embodiment, the mounting bracket 2 has a side wall surface matched with the stop end surface 3234, and the side wall surface is a vertical plane.

[0035] In the embodiment, the smooth curved surface of the inner side surface 3231 of the corner part 323 is a circular arc surface with a fillet radius of 5mm or more. By setting such a way, uniform and smooth glue coating can be achieved, and defects such as unevenness, overflow or bubble voids during glue coating can be prevented.

[0036] Please continue to see Fig. 2 and Fig. 3 As shown in the figure, the headlamp bottom shell 3 is a plastic injection molding part, and due to the different shapes of the inner side surface 3231 and the outer side surface 3232 of the corner part 323, especially the outer side surface 3232 forms a substantially vertical fold surface, so that a relatively thick plastic injection molding block is formed between the outer side surface 3232 and the inner side surface 3231. The relatively thick plastic injection molding block is prone to shrinkage and stress concentration. Therefore, further in the embodiment, the corner part 323 further includes a glue reduction groove 3233 arranged between the outer side surface 3232 and the inner side surface 3231. In this way, the injection molding area at the corner part 323 can be greatly reduced, which not only reduces the risk of injection molding shrinkage, reduces material consumption and production cost, but also effectively disperses stress concentration, further improves the quality control level of the glue coating process. In the embodiment, the glue reduction groove 3233 is formed in a triangular prism shape; in other embodiments, it can also be a cylindrical shape or other shapes.

[0037] Please see Fig. 3 Fig. 3As shown, further, the glue groove 31 is provided with a reinforcing protrusion 324 connected with the corner portion 323 and the smooth transition wall 328. The reinforcing protrusion 324 can enhance the structural strength of the corner portion 323 and the smooth transition wall 328, prevent the glue groove 31 from deforming, and improve the structural stability. In other embodiments, the reinforcing protrusion 324 can be connected with only one of the corner portion 323 or the smooth transition wall 328. The reinforcing protrusion 324 can be protruded inwardly into the glue groove 31. Of course, it can also be protruded outwardly from the glue groove 31, i.e., form a recess in the glue groove 31. The reinforcing protrusion 324 needs to be smoothly arranged to avoid hindering the flow of the adhesive applied in the glue groove 31.

[0038] The application also provides a vehicle comprising a front bumper 1, a headlamp assembly, and a mounting structure of the front bumper 1 and the headlamp as described in any of the above embodiments.

[0039] During installation, the front bumper 1 is mounted with the headlamp bottom shell 3 through the mounting bracket 2 supported on the low-position support portion 321, the edge of the mounting bracket 2 is in contact with the stop end surface 3234 of the corner portion 323 to define the installation position of the mounting bracket 2 on the headlamp bottom shell 3, and then the mounting bracket 2 and the headlamp bottom shell 3 are connected and fixed through screws, buckles, adhesives, or other connection methods.

[0040] As known from the above description of the specific embodiments, the mounting structure of the front bumper 1 and the headlamp provided by the application has the following advantages. At least one glue groove wall 32 forming a glue groove 31 is arranged to include a low-position support portion 321 and a high-position extension portion 322, the low-position support portion 321 and the high-position extension portion 322 are connected in a stepped manner, and an angle portion 323 is formed between the two. A mounting bracket 2 is supported on the low-position support portion 321, the corner portion 323 can limit the mounting bracket 2 when the mounting bracket 2 and the headlamp bottom shell 3 are installed, the corner portion 323 has an inner side surface 3231 and an outer side surface 3232, the inner side surface 3231 is a smooth curved surface transitionally connected between the low-position support portion 321 and the high-position extension portion 322, and the outer side surface 3232 is an angular folded surface intersecting to form an angle. In this way, the outer side surface 3232 can match the mounting bracket 2, play a role in installation limiting and reducing assembly gap, improve the assembly precision and aesthetic degree of the front bumper 1 and the headlamp bottom shell 3, the inner side surface 3231 does not affect the uniformity of the glue application, and does not affect the glue application sealing performance on the headlamp bottom shell 3.

[0041] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0042] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope.
