It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 4 Now, the front bumper assembly provided by the utility model is described. The front bumper assembly includes a front bumper body 20 and a front bumper lower grille; wherein, the front bumper body 20 is provided with an air inlet 200, and the front bumper lower grille includes a lower grille body 10, and the lower grille body 10 is provided with a plurality of connection points, each of which is spaced around the air inlet 200 of the front bumper body 20, and the lower grille body 10 and the front bumper body 20 are connected through each connection point; the upper boundary of the lower grille body 10 is partially extended to form a lifting part 100, and the lifting part 100 is fixed to the front bumper body 20, and the lifting part 100 is connected to the body sheet metal.

[0027] It should be noted that the above-mentioned connection points can all be card connections, or all be screw connections, or some card connections and some screw connections. Considering the convenience of disassembly and assembly and the connection stability, it is preferred to adopt a combination of some card connections and some screw connections.

[0028] The lifting portion 100 is actually a part of the lower grille body 10, or the lifting portion 100 is integrally formed on the lower grille body 10. Since the lower grille body 10 is the lowest component of the front bumper assembly, the lifting portion 100 is arranged at the upper boundary of the lower grille body 10. The lifting portion 100 is fitted and fixed to the front bumper body 20, which can improve the connection reliability between the lower grille body 10 and the front bumper body 20. At the same time, the lifting portion 100 is connected to the body sheet metal (specifically, it can be the front anti-collision beam of the body) with the help of the lifting portion 100, so as to form an upward support for the front bumper body 20, so as to avoid the front bumper body 20 sinking due to the bumps and vibrations of the vehicle and the appearance problem.

[0029] Compared with the prior art, the front bumper assembly provided in the present embodiment connects the lower grille body 10 and the front bumper body 20 as a whole through a plurality of connection points arranged around the air inlet 200, and connects the lower grille body 10 to the body sheet metal by utilizing the lifting portion 100 formed by the partial extension of the upper boundary of the lower grille body 10, thereby improving the assembly reliability of the lower grille body 10 and the front bumper body 20 and avoiding the phenomenon that the lower grille of the front bumper sinks and is misaligned due to vehicle bumps or vibrations; the lifting portion 100 and the lower grille body 10 are an integral structure, and there is no need to separately develop and produce a bracket between the lower grille body 10 and the body sheet metal, thereby reducing R&D and production costs, and also saving assembly time during assembly, thereby reducing assembly labor costs.

[0030] In some embodiments, such as Figure 2 and Figure 6 As shown, a sealing platform 13 is provided at the lower edge of the lower grille body 10 , and the sealing platform 13 abuts against the radiator guide plate along the front-rear direction of the vehicle body.

[0031] It should be explained that in order to avoid air leakage from the lower side of the radiator deflector, it is usually necessary to adopt a two-color injection molding process to process the radiator deflector, and a relatively soft material is used at the lower edge of the radiator deflector to form an extrusion seal with the surface of the front bumper body 20. Since the radiator deflector needs to adopt a two-color injection molding process, the mold development cost and material cost are relatively high. In order to save costs, this embodiment sets a sealing platform 13 at the lower edge of the lower grille body 10, and the flat surface of the sealing platform 13 is used to abut against the plate surface of the radiator heat conduction plate, so as to avoid downward air leakage, so that the air intake of the grille hole 121 is all guided to the radiator, thereby ensuring the heat dissipation efficiency. At the same time, there is no need to set a sealing structure for the radiator deflector, thereby reducing production costs.

[0032] For some possible implementations, see Figure 5 and Figure 6 The lower grille body 10 has a plurality of vertical ribs 12 spaced apart in the width direction of the vehicle body, and grille holes 121 are formed between adjacent vertical ribs 12 . Both ends of the lower grille body 10 each have at least one grille hole 121 with a sealing plate 122 therein.

[0033] Here, by providing the vertical ribs 12, on the one hand, the structural strength of the lower grille body 10 can be improved, and on the other hand, the area between the vertical ribs 12 can be used to form grille holes 121; considering that the lower grille body 10 is mainly used for ventilation and heat dissipation toward the radiator, and the radiator usually only occupies a part of the body width dimension close to the center axis of the body, of course, different vehicles have different requirements for heat dissipation and ventilation area, but the number of grille holes 121 can be opened based on the actual ventilation area requirements of the vehicle model, that is, grille holes 121 are provided between the vertical ribs 12 in the middle area of ​​the lower grille body 10, and closed grilles are used between the vertical ribs 12 at both ends of the lower grille body 10 (that is, grille holes 121 are not formed between the vertical ribs 12, but sealing plates 122 are provided between the vertical ribs 12 to block the grille holes 121). In this way, ventilation and heat dissipation of the radiator can be ensured, and the structural strength of the lower grille body 10 can be improved by using the overall structure formed by the connection of the vertical ribs 12 and the sealing plates 122. Compared with the method of increasing the thickness at both ends to increase the strength, the material cost can be greatly reduced.

[0034] For example, the vertical ribs 12 are V-shaped ribs or U-shaped ribs with the mouth extended backward, which can not only improve the structural strength of the vertical ribs 12, but also reduce the material and reduce the wind resistance. For the grille holes 121 provided with the sealing plates 122, the two sides of the sealing plates 122 can be connected to the two side edges of the mouth of the vertical ribs 12 to form an integral structure, thereby ensuring the structural strength.

[0035] For some examples, see Figure 5 The edges of the lower grille body 10 are provided with flanged ribs 11 that are folded toward the rear side of the vehicle body. The flanged ribs 11 are arranged along the border of the lower grille body 10, which can improve the structural strength of the edges of the lower grille body 10. Compared with the method of achieving structural reinforcement by increasing the thickness of the edge material, the material consumption can be reduced, which is not only conducive to reducing costs, but also conducive to reducing weight.

[0036] It should be noted that see Figure 2 and Figure 4 The front bumper assembly further includes a license plate mounting frame 30. The lifting portion 100 is connected to the front bumper body 20 via at least one fastener 40, and each fastener 40 is shielded at the rear side of the license plate mounting frame 30. The fastener 40 may be a screw or a rivet. The connection strength between the lifting portion 100 and the front bumper body 20 may be improved by the fastener 40. Specifically, three fasteners 40 distributed in a triangle may be used to fit and fix the lifting portion 100 on the front bumper body 20. In order to avoid the fasteners 40 being exposed and affecting the appearance of the front bumper body 20, each fastener 40 is shielded by the license plate mounting frame 30.

[0037] Based on the same inventive concept, Figures 1 to 7It is understood that the embodiment of the present application also provides a front bumper assembly, including a front bumper body 20, a license plate mounting frame 30 provided on the front bumper body 20, and the above-mentioned front bumper lower grille.

[0038] It should be noted that the front bumper assembly provided in this embodiment may also include an upper grille, and for currently common new energy vehicle models, the upper grille may not be provided.

[0039] Compared with the prior art, the front bumper assembly provided in the present embodiment adopts the above-mentioned front bumper lower grille, and can connect the lower grille body 10 to the body sheet metal by utilizing the lifting portion 100 formed by the local extension of the upper boundary of the lower grille body 10, thereby improving the assembly reliability of the lower grille body 10 and the front bumper body 20, and avoiding the phenomenon of the front bumper lower grille sinking and misalignment caused by vehicle bumps or vibrations; the lifting portion 100 and the lower grille body 10 are an integral structure, and there is no need to separately develop and produce a bracket between the lower grille body 10 and the body sheet metal, thereby reducing R&D and production costs, and at the same time, it can also save assembly time during assembly, thereby reducing assembly labor costs.

[0040] For some examples, see Figure 3 , Figure 4 and Figure 6 A plurality of first receiving grooves 101 are spaced apart on the supporting portion 100, and a plurality of first connecting seats 21 are provided on the front bumper body 20. Each first connecting seat 21 extends backward into each first receiving groove 101 respectively, and each first connecting seat 21 is screwed and fixed to the bottom wall of the corresponding first receiving groove 101 by a fastener 40.

[0041] The fastener 40 can specifically be a bolt, and the first connecting seat 21 extending backward is extended into the first accommodating groove 101 to realize the screw connection and fixation of the lifting part 100 and the front bumper body 20, which can avoid the appearance of connecting protrusions on the front surface of the front bumper body 20, thereby ensuring the surface quality of the front bumper body 20.

[0042] On the basis of the above, the license plate mounting frame 30 is shielded in front of each first connection seat 21, and the license plate mounting frame 30 is connected to at least one first connection seat 21. At the same time, the license plate mounting frame 30 is used to shield each first connection seat 21, so as to avoid the fastener 40 from being exposed and affecting the appearance and texture; on this basis, the license plate mounting frame 30 and the lifting part 100 can share the same first connection seat 21 for screw connection and fixation, thereby improving the compactness of the structure.

[0043] For example, see Figure 3 and Figure 6A plurality of second receiving grooves 102 are spaced apart around the edges of the lower grille body 10, and each second receiving groove 102 forms a connection point; a plurality of second connecting seats 22 are provided on the front bumper body 20, and each second connecting seat 22 extends backward into each second receiving groove 102 respectively, and each second connecting seat 22 is screwed and fixed to the bottom wall of the corresponding second receiving groove 102 by a fastener 40.

[0044] Here, the fastener 40 can be a bolt, and the rearward protruding second connecting seat 22 is extended into the second accommodating groove 102 to realize the screw fixation of the lower grille body 10 and the front bumper body 20. This can not only avoid the appearance of connecting protrusions on the front surface of the front bumper body 20, thereby ensuring the surface quality of the front bumper body 20, but also the screw fixation method is stable and reliable, which can avoid the connection misalignment between the lower grille body 10 and the front bumper body 20 caused by the bumps and vibrations of the vehicle.

[0045] For an example, see Figure 4 , Figure 6 and Figure 7 The lower grille body 10 is provided with a plurality of snap holes 103 at intervals around the edges thereof, and each snap hole 103 forms a connection point; the front bumper body 20 is provided with a plurality of snap buckles 23, and each snap buckle 23 is snapped into each snap hole 103 in a corresponding manner. Inserting the snap buckles 23 into the snap holes 103 to form snap-fit ​​can reduce the amount of fasteners 40 used, and can facilitate disassembly and assembly, thereby improving assembly efficiency.

[0046] It should be understood that in this embodiment, on the basis of the multiple clips 23 and the multiple clip holes 103 cooperating to snap-fit, multiple second connecting seats 22 and second accommodating grooves 102 can be added for screw fixation. Specifically, the four corner positions of the lower grille body 10 can be screwed and fixed, and the remaining edge positions surrounding the air inlet 200 can be connected with spaced snap-fit ​​points, thereby ensuring the connection stability and facilitating assembly.

[0047] Based on the same inventive concept, the present application also provides a vehicle, including the above-mentioned front bumper assembly.

[0048] Compared with the prior art, the vehicle provided in this embodiment adopts the above-mentioned front bumper assembly, and can use the lifting portion 100 formed by the local extension of the upper boundary of the lower grille body 10 to connect the lower grille body 10 with the body sheet metal, thereby improving the assembly reliability of the lower grille body 10 and the front bumper body 20, and avoiding the phenomenon of the lower grille of the front bumper sinking and misalignment caused by vehicle bumps or vibrations; the lifting portion 100 and the lower grille body 10 are an integrated structure, and there is no need to separately develop and produce a bracket between the lower grille body 10 and the body sheet metal, thereby reducing R&D and production costs, and at the same time, it can also save assembly time during assembly, thereby reducing assembly labor costs.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
