[0032] The front bumper of a car has decorative, heat dissipation and protective functions. A beautiful front bumper will give the car a better overall appearance. Therefore, when designing the appearance of a car, designers usually focus on the design of the front bumper. The structure of the front bumper of a car generally includes a bumper, a grille and wiring harnesses for powering various electrical accessories. Currently, the connection between the bumper and the grille is usually snap-on.

[0033] The inventor has observed and found that during the use of some mainstream models, the connection area between the bumper and the grille often sinks and deforms. The reason for this phenomenon is that the bumper and grille of this type of model are connected in an up-down clamping manner, that is, a flange is set at the edge of the bumper, and the bumper flange is clamped from top to bottom into the inner side of the grille. This clamping method will cause the length of the bumper flange entering the inner side of the grille to be shorter, resulting in insufficient strength of this part. During the use of the car, the grille will sink and deform due to the weight of the grille and other external forces. This deformation will seriously affect the appearance and texture of the car. Some technicians in the industry will lengthen the length of the bumper flange entering the inner side of the grille to solve the above problem, but the inventor has found that this improvement plan will reduce the grille opening air intake area. For some models, the opening air intake area is insufficient. If this improvement plan is adopted, it will cause poor heat dissipation of the car, causing the internal structure of the car to overheat while driving, which is easy to cause failures.

[0034] In view of the above-mentioned current situation, the utility model proposes a front bumper structure of an automobile, aiming to solve the problems in the above-mentioned technical background.

[0035] In order to solve the technical problem of the sinking and deformation of the flange of the bumper 1, the utility model proposes a front bumper structure of an automobile. In one embodiment of the utility model, please refer to Figures 1 to 3 The front bumper structure of an automobile includes a bumper 1 and a grille 2, wherein the grille 2 includes a grille outer side X and a grille inner side Y facing the automobile body; the grille 2 is provided with a mounting portion 21, and the bumper 1 is provided with a connecting portion 11, and the grille 2 is connected to the bumper 1 through the mounting portion 21 and the connecting portion 11; the mounting portion 21 includes a mounting hole 2111, and the size of the mounting hole 2111 is larger than the size of the connecting portion 11; the connecting portion 11 extends from the grille outer side X through the mounting hole 2111 into the grille inner side Y and is clamped with the mounting portion 21.

[0036] Specifically, during processing, installation areas for the bumper 1 and the grille 2 are reserved for both. The bumper 1 and the grille 2 are snap-fitted so that the grille 2 can be installed on the bumper 1. A connecting portion 11 is provided in the installation area of ​​the bumper 1, and a mounting portion 21 is provided in the installation area of ​​the grille 2. A mounting hole 2111 is formed in the mounting portion 21. In order to enable the connecting portion 11 to enter the mounting hole 2111, the size of the mounting hole 2111 is slightly larger than the size of the connecting portion 11. When the grille 2 is snap-fitted to the bumper 1, the connecting portion 11 extends itself into the mounting hole 2111, enters the inner side Y of the grille through the mounting hole 2111, and completes the snap-fitting with the mounting portion 21.

[0037] The technical solution provided by the utility model is to set a connecting portion 11 on the bumper 1 and a mounting portion 21 on the grille 2, so that the connecting portion 11 can extend from the outer side X of the grille into the inner side Y of the grille to be clamped with the mounting portion 21, and then the grille 2 is fixed on the bumper 1, so that the connecting area between the bumper 1 and the grille 2 no longer has a flange, shortening the length of the convex structure of the bumper connecting area, solving the problem of the flange edge length of the bumper 1 being too short, and the grille 2 itself has sufficient length in the upper and lower parts of the connecting area, so this installation method improves the strength of the connecting area between the bumper 1 and the grille 2 as a whole, thereby avoiding the problem of sinking and deformation at the flange of the bumper 1; in addition, since the technical solution provided by the utility model does not increase the length of the flange part of the bumper 1, it will not affect the opening air intake area of ​​the grille 2.

[0038] See also Figure 3In one embodiment of the utility model, the mounting portion 21 further comprises a clamping block 211, the clamping block 211 is formed with a mounting hole 21111, the connecting portion 11 comprises a connecting piece 111 extending into the mounting hole 2111 and a connecting head 112 arranged at one end of the connecting piece 111 near the inner side Y of the grille, the connecting head 112 comprises an undercut 1121, and the undercut 1121 abuts against the clamping block 211. Specifically, the part of the grille 2 surrounding the mounting hole 2111 is the clamping block 211, the thickness of the clamping block 211 is determined according to the design of different vehicle models, the connecting portion 11 extends from the bumper 1, comprises a connecting piece 111 and a connecting head 112, the connecting piece 111 and the connecting head 112 are integrally formed or welded, or even screwed; the connecting head 112 is provided with an undercut 1121, and the undercut 1121 abuts against the clamping block 211, so that the connecting portion 11 can be clamped with the mounting portion 21, so that the grille 2 can be clamped with the bumper 1.

[0039] In one embodiment of the present invention, the mounting portion 21 further includes a fixing block 212, which is disposed inside the mounting hole 2111, one end of the fixing block 212 is connected to the inner wall surface of the mounting hole 2111, and the other end of the fixing block 212 is in contact with the connecting piece 111. Figure 2 and Figure 3 After the connecting portion 11 and the mounting portion 21 are snapped together, the connecting piece 111 is located inside the mounting hole 2111. Since the thickness of the connecting piece 111 is smaller than the height of the mounting hole 2111, there is a gap between the two. This gap may cause the connecting piece 111 to move inside the mounting hole 2111, affecting the snap-in quality. Therefore, a fixing block 212 is provided inside the mounting hole 2111. One end of the fixing block 212 is connected to the inner wall surface of the mounting hole 2111, and the other end abuts against the connecting piece 111, so that the fixing block 212 can be pressed on the surface of the connecting piece 111, thereby fixing the connecting piece 111 and making the snap-in between the mounting portion 21 and the connecting portion 11 more stable.

[0040] Further, in an embodiment of the present invention, there are two fixing blocks 212, which are symmetrically arranged along the central axis of the mounting hole 2111, and the length of the connector 112 along the connecting line of the ends of the two fixing blocks 212 is less than the distance between the two fixing blocks 212. Figure 2Two fixing blocks 212 are arranged in the mounting hole 2111, and the ends of the two fixing blocks 212 are both in contact with the connecting piece 111. The two fixing blocks 212 are symmetrically arranged along the central axis of the mounting hole 2111. In the direction of the connecting line at the ends of the two fixing blocks 212, the connector 112 has a length that is smaller than the clear distance between the two fixing blocks 212, so that the connector 112 can pass through the gap between the two fixing blocks 212. Through the above arrangement, the connecting piece 111 can be installed more firmly, and the clamping quality of the mounting portion 21 and the connecting portion 11 is improved.

[0041] According to the embodiment of the utility model, a plurality of mounting portions 21 are arranged along the edge of the grille 2, and the connecting portion 11 is arranged at the edge of the bumper 1. The number of mounting portions 21 and connecting portions 11 is equal and they are arranged one-to-one. In actual situations, there are a plurality of mounting portions 21 and connecting portions 11, and the grille 2 can be installed on the bumper 1 only by cooperating with a plurality of mounting portions 21 and connecting portions 11. When the bumper 1 and the grille 2 are processed, in order to design an aesthetic and avoid blocking the air inlet of the grille 2, the connecting portion 11 is arranged at the edge of the bumper 1, and the mounting portion 21 is also arranged at the edge of the grille 2, and the setting positions of the connecting portion 11 and the mounting portion 21 correspond one-to-one to ensure that the two can be snap-fitted one-to-one.

[0042] In addition to the above structure, there are also wiring harnesses 3 in the front bumper structure of the car that supply power to various electrical accessories. These wiring harnesses 3 need to be combed and fixed during the automobile processing process. Currently, finished wiring harness clamps are often used to achieve this purpose. However, when using the finished wiring harness clamps, it is necessary to make matching holes on the grille 2, and then install the wiring harness clamps. Finally, the wiring harness 3 is installed in the wiring harness clamps and tied and tightened. The process is relatively complicated, and the finished wiring harness clamps have a certain cost. How to reduce this part of the cost is also a problem currently faced by some car companies.

[0043] See also Figure 4 Considering that the automobile front bumper structure also includes a wiring harness 3, in one embodiment of the utility model, the grille 2 also includes a wiring harness fixing member 22, and the wiring harness 3 is clamped to the wiring harness fixing member 22. The structure of the wiring harness fixing member 22 is shown in FIG. Figure 5 The wire harness fixing part 22 is installed on the grille 2, and the wire harness fixing part 22 includes a first fixing piece 221 and a second fixing piece 222. The first fixing piece 221 and the second fixing piece 222 are fixedly connected at one end close to the grille 2, and the first fixing piece 221 and the second fixing piece 222 form a fixing space 223. The other ends of the first fixing piece 221 and the second fixing piece 222 form an opening 224 connected to the fixing space 223.

[0044] Specifically, the wire harness fixing part 22 is integrally installed on the inner side Y of the grille. The wire harness fixing part 22 is integrally formed with the grille 2 or connected by welding, and can even be connected by screws. The wire harness fixing part 22 includes a first fixing piece 221 and a second fixing piece 222. One end of the first fixing piece 221 and the second fixing piece 222 are connected together so that the first fixing piece 221 and the second fixing piece 222 form a whole. The first fixing piece 221 and the second fixing piece 222 form a fixing space 223, and the fixing space 223 is used to fix the wire harness 3; the other end of the first fixing piece 221 and the second fixing piece 222 is formed with an opening 224 connected to the fixing space 223, and the wire harness 3 can enter the fixing space 223 through the opening 224, so that the wire harness 3 is fixed on the grille 2; in one embodiment, the wire harness fixing part 22 is integrally formed with the grille 2, which can reduce the workflow in the work of fixing the wire harness 3 and save the cost of using a wire harness clamp.

[0045] In one embodiment of the present invention, the size of the clamping space 223 gradually decreases from the middle of the clamping space 223 to both ends. Specifically, in order to fit the external shape of the wiring harness 3, the distance between the inner wall surfaces of the middle of the first clamping piece 221 and the second clamping piece 222 is the largest, and the distance between the inner wall surfaces of the two gradually decreases toward the two ends. At one end of the first clamping piece 221 and the second clamping piece 222 close to the grille 2, since the first clamping piece 221 and the second clamping piece 222 are connected together, the distance between the inner wall surfaces of the two is zero.

[0046] There are many forms of implementation of the wire harness fixing 22. In another embodiment of the present invention, the wire harness fixing 22 also includes a substrate. The first fixing piece 221 and the second fixing piece 222 are installed on the substrate near one end of the grille 2. The substrate can be installed on the grille 2 by welding or gluing, or by screws. This can avoid pre-reserving holes on the grille 2 and reduce the processing flow of the grille 2. At the same time, it also improves the flexibility of the installation of the wire harness fixing 2 and realizes flexible production.

[0047] In another embodiment of the utility model, the harness fixing member 22 also includes a base and a screw, the base is installed on the grille 2, the base is formed with a hole, and the inner wall surface of the hole is provided with a thread; the screw is fixedly connected to the base, and the first clamping piece 221 and the second clamping piece 222 are connected to the base through the base and the screw. The base can be integrally formed with the grille 2, and a hole is reserved, and the inner wall surface of the hole is provided with a thread for installing a matching screw; the first clamping piece 221 and the second clamping piece 222 are installed on the base near one end of the grille 2, the base is fixedly connected with the screw, and the screw cooperates with the preset thread in the base, so that the first clamping piece 221 and the second clamping piece 222 can be installed on the base, and the harness is fixed on the grille 2. Through this scheme, the first clamping piece 221 and the second clamping piece 222 of various sizes can be installed on the grille 2, so that it can be used to fix harnesses of different widths or diameters, thereby improving the applicability of the harness fixing member 22.

[0048] In the technical solution provided by the utility model, the automobile front bumper structure includes both the installation parts on the bumper 1 and the grille 2, namely the connecting part 11 and the installing part 21, and the wiring harness fixing part 22 installed on the inner side Y of the grille. The position of the wiring harness fixing part 22 on the inner side Y of the grille can be adjusted according to the routing of the wiring harness 3 of different vehicle models. In this way, the automobile front bumper structure in the utility model can solve the problem of the sinking and deformation of the bumper flange without affecting the opening air intake area of ​​the grille 2, and can also reduce the work flow of fixing the wiring harness 3, while saving the cost of using the wiring harness clamp.

[0049] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
