Description

Technical Field

[0001] The invention relates to the field of automobile body structures, in particular to a front bumper mounting structure. Background Art

[0002] The front-end styling of the vehicles in the current patents is relatively flat. For some off-road vehicles with more protruding front-end styling, it is not easy to meet the leg shape requirements of GB or European pedestrian protection regulations, so the design limits the personalized styling; or a more costly method is used to meet the mandatory requirements of the regulations.

[0003] Chinese patent CN115257621A discloses a front energy-absorbing anti-collision beam assembly for protecting pedestrians in automobiles. Two metal energy-absorbing crossbeams are added to the anti-collision beam position, requiring additional parts. Chinese patent CN115214523A discloses a calf protection device, a front-end pedestrian protection device for a vehicle, and a vehicle. It proposes a calf protection bracket and a drive device. The calf protection bracket can actively drop down when encountering a pedestrian collision. It is particularly suitable for off-road vehicles. However, due to the addition of a drive device, the technology is relatively complex and the cost is correspondingly high. Chinese patent CN113147641A discloses a bumper mounting structure that is beneficial for pedestrian protection. It proposes a front center bracket with a hollow structure with a flanged middle. In addition to having installation strength, it can also effectively protect the pedestrian's calf and knees in the event of a low-speed collision between a car and a pedestrian. However, the front center bracket of this structure is large, occupies a large space, and is not compact enough.

[0004] The existing front-end structure of automobiles that meets pedestrian protection regulations is relatively complex, requires a large number of parts, and occupies a large space. At the same time, considering the special styling of off-road vehicles, it is necessary to propose a front protection installation structure and installation method that meets regulatory requirements.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] As shown in the figure, this embodiment provides a front bumper installation structure, including a middle bracket 101, an upper bumper 102, a lower bumper 103 and a vehicle body front end structure 200;

[0037] The middle bracket 101 is located in the middle of the upper support 102. Two extension shells (S in the figure) extend from the front end of the middle bracket 101. The two extension shells are symmetrical about the Y=0 plane of the vehicle, and the middle bracket 101 is a hollow "U"-shaped structure; Figure 7 As shown, the back of the middle bracket 101 is an annular groove structure, and a number of reinforcing ribs are provided in the annular groove for support. The shells on both sides of the middle bracket 101 have a tendency to bulge towards the front end, which maximizes the support strength on the basis of structural weakening.

[0038] Reference Figures 7 to 9 As shown, the middle bracket 101 is made of plastic, and the upper end surface 106 of the middle bracket 101 is provided with a mounting hole. The upper end surface 106 is fixedly connected to the middle bracket 105-1 on the upper part of the lower support 103 by bolts. The upper end surface of the middle bracket 101 extension shell is opened with a hole size of 75mm-10mm, which is used to weaken and cooperate with the Z-direction support, and the center line distance between the two symmetrical extension shells is 120mm. Figure 4 As shown, the upper surface of the extended shell of the middle bracket 101 is in contact with the structural surface 401 of the lower guard 103. It plays a Z-direction support role to prevent the front guard from being greatly deformed in the middle position.

[0039] The center of the upper guard 102 is U-shaped; this U-shaped structure offers excellent bending resistance. Clips are installed inside the center of the upper guard 102, spaced 110 mm apart. The upper end of the lower guard 103 is provided with slots, spaced 110 mm apart. These clips engage securely. When assembled, the two form a crossbeam with a cavity structure, offering excellent bending resistance.

[0040] A metal lower guard mounting bracket 201 is provided in the middle of the left and right ends of the front end structure 200. It is fixedly connected to the lower guard 103. A crash beam 202 is provided at the lower front end of the front end structure 200. The middle portion of the crash beam 202 has a mounting hole 204 for fixed connection to the middle bracket 101. A cross beam 203 is provided at the lower front end of the front end structure 200 for fixed connection to the lower guard 103.

[0041] The lower end face 107 and the lower side face 108 of the middle bracket 101 are both provided with mounting holes, wherein the lower end face 107 is fixed to the middle upper end face of the anti-collision beam 202 by bolts, and the lower side face 108 is fixed to the middle front end face 205 of the anti-collision beam 202 by bolts.

[0042] A lower buckle 104 is provided on the lower side of the lower protector 103 , and the lower buckle 104 is fixed to the crossbeam at the lower end of the vehicle body front end structure 200 .

[0043] Side brackets 105 are provided on both sides of the upper portion of the lower guard 103 for connecting to the lower guard mounting bracket 201 of the vehicle body front end structure 200. Lower guard 103 is provided with two side brackets 105 and two intermediate brackets 105-1, each 110 mm wide.

[0044] The key points of this embodiment are: the middle bracket 101 avoids the damage of the Y=0 and Y=100 leg types through special design, weakened extension shell and special distribution. At the same time, the extension shell can also play a Z-direction support role for the front guard. The lower end of the middle bracket 101 has 4 fixing points, which are fixed on the top and side of the anti-collision beam respectively. This structure allows the middle bracket 101 to have the ability to resist X-direction impact and have Z-direction support capability; the upper end of the front guard installation structure has four fixing points, two at both ends and two in the middle, and the upper end forms a certain cross-section. The crossbeam structure, the installation structures on the left and right sides of the upper end (i.e., the lateral brackets 105 of the lower guard) have a wider structure, which maximizes the X-direction impact resistance of the leg type and the maximum width. The two middle fixing points are fixed above the middle bracket. Because the middle bracket has the support capabilities in the X and Z directions, the two middle fixing points also have the support capabilities in the X and Z directions, which plays a beneficial role in the pedestrian protection leg type test; the front guard structure and installation method of the present invention can meet the leg type test requirements of the national and European pedestrian protection regulations, and at the same time meet the installation and use requirements.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
