[0036] Besides styling and color, gaps and surface differences in a car's exterior are crucial factors affecting its aesthetics. The gap between the front bumper and hood is one of the most noticeable areas on a car's exterior, and ensuring that this gap and surface difference meet DTS (Design for Quality) and sensory quality requirements is a challenge for all OEMs. The surface difference between the front bumper and hood is ensured by the precision of the hood, bumper, and body components themselves. However, this gap has a long dimensional chain and large accumulated tolerances, resulting in significant deviations in the surface difference, making it difficult to meet DTS and sensory quality requirements. Generally, adjusting the hood's position can mitigate this, but this adjustment affects the surface difference between the hood and fenders. It's difficult to simultaneously address both gaps, often resulting in compromises and making adjustments very cumbersome.

[0037] In view of this, the present invention provides an automobile, Figures 1 to 10 The embodiments of the automobile provided by the present invention are as follows: since the present invention mainly focuses on the front bumper, other structures of the automobile are omitted, and reference can be made to the prior art.

[0038] like Figure 1 As shown, the present invention proposes an automobile comprising a front frame or crossbeam 1 (the front frame is shown in the figure), an engine hood (not shown in the figure), and a front bumper. The front bumper includes a front bumper body 3 and a decorative element 4 (three decorative segments 43 are shown in the figure). The decorative element 4 is used to cover the gap formed between the engine hood and the front bumper body 3. The front bumper body 3 is movably adjustable in the height direction of the automobile and is mounted on the front frame or crossbeam 1. The decorative element 4 is movably adjustable in the width direction of the gap and is mounted on the front bumper body 3, thereby making the gap and surface difference between the front bumper and the engine hood adjustable.

[0039] In the technical solution of the present invention, the position of the front bumper body 3 in the vehicle height direction can be adjusted to match the engine hood based on the position of the engine hood along the vehicle height direction. Then, based on the gap formed between the engine hood and the front bumper body 3, the position of the decorative part 4 in the width direction of the gap can be adjusted so that the decorative part 4 covers the gap formed between the engine hood and the front bumper body 3. During the entire adjustment process, it is not necessary to change the position of the engine hood, and it does not affect the gap surface difference between the engine hood and the fender. That is, the position of the front bumper in the vehicle height direction and the width direction of the gap can be adjusted separately according to the actual position of the engine hood, so as to realize the adjustment of the gap and surface difference between the front bumper and the engine hood, thereby making the adjustment of the gap and surface difference between the front bumper and the engine hood convenient.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, the vehicle also includes a transition bracket 2, which is movably and adjustable in the vehicle height direction and is mounted on the front frame or crossbeam 1. The front bumper body 3 is fixed to the transition bracket 2. Thus, the position of the front bumper body 3 in the vehicle height direction can be indirectly adjusted by adjusting the position of the transition bracket 2 in the vehicle height direction, making the adjustment more convenient.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the vehicle also includes a first positioning structure and a first fastening structure. The first positioning structure includes a first positioning part 21 and a first positioning mating part 11 respectively disposed on the transition bracket 2 and the front frame or crossbeam 1. The first positioning part 21 and the first positioning mating part 11 cooperate with each other to position the transition bracket 2 on the front frame or crossbeam 1 in the vehicle width direction and to adjust it relative to the front frame or crossbeam 1 in the vehicle height direction. The first fastening structure includes a first fastening part 22 and a first fastening mating part 12 respectively disposed on the transition bracket 2 and the front frame or crossbeam 1. The first fastening part 22 and the first fastening mating part 12 cooperate with each other to fasten the transition bracket 2 to the front frame or crossbeam 1 in the vehicle length direction. Thus, when the transition bracket 2 is installed on the front frame or crossbeam 1, the transition bracket 2 is fastened in the vehicle length direction, positioned in the vehicle width direction, and adjustable in the vehicle height direction, realizing that the transition bracket 2 is movably and adjustablely disposed on the front frame or crossbeam 1 in the vehicle height direction.

[0042] In one embodiment, one of the first positioning part 21 and the first positioning mating part 11 is a positioning hole 211, and the other is a positioning pin 111 passing through the positioning hole 211. The dimensions of the positioning hole 211 in the vehicle width direction are adapted to the dimensions of the positioning pin 111 in the vehicle width direction, and the dimensions of the positioning hole 211 in the vehicle height direction are larger than the dimensions of the positioning pin 111 in the vehicle height direction. Thus, the positioning pin 111 can move within the positioning hole 211 in the vehicle height direction, thereby realizing the position adjustment of the transition bracket 2 in the vehicle height direction. Specifically, the positioning hole 211 is an oblong hole, and the positioning pin 111 has a cross-shaped cross-section, which facilitates convenient adjustment of the dimensions of the positioning pin 111 by cutting or other methods.

[0043] The present invention does not limit the specific structure of the first fastening part 22 and the first fastening mating part 12. In one embodiment, the first fastening part 22 and the first fastening mating part 12 include two first through holes arranged opposite each other for fastening with a first threaded fastener. The diameter of the first through hole is larger than the outer diameter of the first threaded fastener. In this way, the transition bracket 2 is fastened in the length direction of the vehicle. In the width direction and the height direction of the vehicle, the first through hole has a margin, for example, the diameter of the first through hole is 10 mm and the diameter of the first threaded fastener is 6 mm. The first threaded fastener passes through the two first through holes to pre-fasten the transition bracket 2. Then, the position of the transition bracket 2 in the height direction is adjusted by the cooperation of the first positioning part 21 and the first positioning mating part 11. Finally, the transition bracket 2 is fixed under the joint action.

[0044] In one embodiment, such as Figures 6 to 9 The vehicle further includes a second positioning structure and a second fastening structure. The second positioning structure includes a second positioning part 31 and a second positioning mating part 41 respectively disposed on the decorative part 4 and the front bumper body 3. The second positioning part 31 and the second positioning mating part 41 cooperate with each other to position the decorative part 4 on the front bumper body 3 in the extension direction of the gap and to adjust it relative to the front bumper body 3 in the width direction of the gap. The second fastening structure includes a second fastening part 32 and a second fastening mating part 42 respectively disposed on the decorative part 4 and the front bumper body 3. The second fastening part 32 and the second fastening mating part 42 cooperate with each other to fasten the decorative part 4 to the front bumper body 3 in the vehicle height direction. Thus, when the decorative part 4 is installed on the front bumper body 3, the decorative part 4 is fastened in the vehicle height direction, positioned in the extension direction of the gap, and adjustable in the width direction of the gap, realizing that the decorative part 4 is movably and adjustablely disposed on the front bumper body 3 in the width direction of the gap.

[0045] In one embodiment, see details. Figure 7 and Figure 9 One of the second positioning part 31 and the second positioning mating part 41 is a positioning groove 311, and the other is a protruding tongue 411 that passes through the positioning groove 311. The protruding tongue 411 has a recessed insertion hole 412 in the thickness direction. The side wall of the positioning groove 311 has a protruding insertion part 312 that engages with the insertion hole 412. There are multiple positioning grooves 311 and protruding tongues 411. In the extension direction of the gap and in the width direction of the gap, the size of the positioning groove 311 is larger than the size of the protruding tongue 411. One of the protruding tongues 411 has a limiting block 413 protruding from its side wall, so that the protruding tongue 411 is positioned by the corresponding positioning groove 311 in the extension direction of the gap. Thus, the protruding tongue 411 with the limiting block 413 is engaged with the corresponding positioning groove 311 as a positioning point. Other positioning grooves 311 have a certain margin, and all protruding tongues 411 can slide within the positioning groove 311 along the width direction of the gap, thereby adjusting the position of the decorative piece 4. This allows the decorative piece 4 to be movably adjusted in the width direction of the gap and positioned on the front guard body 3. For example, as shown in Figure 8, the protruding tongue 411 with the limiting block 413 is located in the middle of multiple protruding tongues 411, serving as a positioning point, which facilitates the position adjustment of the decorative piece 4.

[0046] In one embodiment, such as Figure 6 and Figure 8 As shown, the second fastening part 32 and the second fastening mating part 42 include two opposing second through holes for inserting second threaded fasteners for fastening. The diameter of the two second through holes is larger than the outer diameter of the second threaded fastener, thus achieving fastening of the decorative part 4 in the vehicle height direction. In the vehicle width and vehicle height directions, the second through holes have a margin, for example, the diameter of the second through hole is 10mm and the diameter of the second threaded fastener is 6mm. The second threaded fastener passes through the two second through holes to pre-fasten the decorative part 4. Then, according to the front profile position of the engine hood, the decorative part 4 is adjusted to a suitable position by pushing and pulling in the width direction of the gap, and then fastened with the second threaded fastener to finally fix the decorative part 4.

[0047] In another embodiment, such as Figure 1As shown, the decorative component 4 includes multiple decorative segments 43 arranged sequentially along the extension direction of the gap. One of two adjacent decorative segments 43 is disposed inside the other decorative segment 43, and the two decorative segments 43 are slidably arranged along the extension direction of the gap. In this way, the multiple decorative segments 43 can be adjusted independently without affecting each other, resulting in a better fit. By adjusting the gap surface difference between the front bumper body 3 and the engine hood through the movement of multiple decorative segments 43, the front bumper body 3 will not undergo elastic deformation, and the curvature of the front bumper body 3's appearance surface will not be changed, thus ensuring the light and shadow effect of the front bumper body 3's appearance surface and guaranteeing the service life of the front bumper body 3.

[0048] To achieve sliding and positioning between the two decorative segments 43, in one embodiment, see details below. Figure 8 and Figure 10 A sliding fit structure is provided between two adjacent decorative segments 43. The sliding fit structure includes a sliding post 431 and a sliding groove 432 respectively disposed at one end of each decorative segment 43 that is close to each other. The free end of the sliding post 431 slides into the sliding groove 432 and is limited by the sliding groove 432 in the extension direction of the gap. In this way, when the decorative segment 43 is adjusted in the width direction of the gap, the decorative segments 43 can also generate relative displacement in the extension direction of the gap, avoiding elastic deformation of the decorative segments 43, avoiding unevenness at the overlap between the decorative segments 43, and ensuring the appearance and service life of the decorative part 4. For example, the decorative segment 43 can be provided in three sections. The middle section is mainly located at the front of the car, and the left and right sections extend to the left and right from the headlights. The overlap gap between adjacent decorative segments 43 is set according to the exterior styling lines of the car to ensure the overall appearance.

[0049] The adjustment method for the gap and surface difference between the front bumper and the hood based on the above-mentioned automobile structure is as follows:

[0050] 1. After the engine hood is assembled and adjusted to the appropriate position, the transition bracket 2 is adjusted to match the position of the engine hood in the vehicle height direction according to the position of the engine hood in the vehicle height direction, and then tightened with bolts.

[0051] 2. Assemble the left and right areas of the front bumper body 3 with the left and right fenders.

[0052] 3. Secure the front bumper body 3 to the transition bracket 2. (This invention does not limit the specific method of fixing the front bumper body 3 to the transition bracket 2; for details, please refer to...) Figure 6 and Figure 4 The transition bracket 2 is provided with a first mounting hole 23, and the front bumper body 3 is provided with a second mounting hole 33, which are fastened by inserting bolts.

[0053] 4. Based on the position of the front profile of the engine hood in the width direction of the gap, adjust the decorative piece 4 to a suitable position by pushing and pulling in the width direction of the gap, and then tighten it with screws.

[0054] 5. Finally, the lower area of ​​the front bumper body 3 is fastened to the bottom of the car using clips and bolts.

[0055] Compared with existing technical solutions, this technical solution has at least the following advantages:

[0056] 1. The position of the front bumper in the vehicle height direction and along the width direction of the gap can be adjusted individually according to the actual position of the engine hood to match the gap surface difference and make it meet the DTS and sensory quality requirements.

[0057] 2. When matching the gap between the hood and the front bumper, there is no need to adjust the position of the hood, and it does not affect the surface difference between the hood and the fender.

[0058] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
