Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an automobile. Background Technology

[0002] Besides styling and color, gaps in a car's exterior are also a significant factor affecting its appearance. The gap between the front bumper assembly and the hood is one of the most noticeable areas on a car's exterior, and ensuring that this gap meets DTS (Design for Quality) and sensory quality requirements is a challenge for all OEMs. The gap between the front bumper assembly and the hood is maintained 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 gap's size, making it difficult to meet DTS and sensory quality requirements.

[0012] In one embodiment, the middle bracket is provided with a first limiting hole, and the front bumper is provided with a first limiting pin corresponding to the first limiting hole. The first limiting pin extends along the X-axis direction, and the width of the first limiting hole along the Z-axis direction is adapted to the width of the first limiting pin along the Z-axis direction; and / or

[0013] The middle bracket is provided with a second limiting hole, and the front bumper is provided with a second limiting pin corresponding to the second limiting hole.

[0016] The anti-diving bracket is further provided with a second positioning hole, and the front bumper is provided with a second positioning pin corresponding to the second positioning hole. The second positioning pin extends in the Z-axis direction and is adapted to the second positioning hole; and / or

[0017] The anti-diving support also has a third positioning hole, and the middle support has a third positioning pin corresponding to the third positioning hole. The third positioning pin extends in the X-axis direction, and the third positioning hole and the third positioning pin are adapted to each other and / or

[0018] The anti-diving support also has a first threaded hole, which opens towards the X-axis. The middle support has a first fastening hole corresponding to the first threaded hole. A first threaded bolt passes through the first threaded hole and is connected to the first fastening hole. The diameter of the first threaded hole is larger than the outer diameter of the first threaded bolt; and / or

[0019] The anti-diving bracket is also provided with a second threaded hole, which opens in the Z-axis direction. The middle bracket and the front bumper are respectively provided with a second fastening hole and a third fastening hole corresponding to the second threaded hole.

This allows the front bumper assembly to be adjusted along the X-axis towards the front frame. Since the hood has a fixed closed state relative to the front frame, adjusting the relative position of the front bumper assembly and the front frame along the X-axis effectively adjusts the relative position of the front bumper assembly and the hood along the X-axis. This allows for the absorption of tolerances by moving the front bumper assembly, thereby adjusting the gap between the front bumper assembly and the hood and achieving precise control over the gap. Furthermore, the entire adjustment process does not require changing the position of the hood, and does not affect the surface difference between the hood and the fender. In other words, the position of the front bumper assembly along the X-axis can be adjusted independently based on the actual position of the hood, thus achieving convenient adjustment of the gap between the front bumper assembly and the hood.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0041] This utility model proposes an automobile.

[0042] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment of the present invention, the automobile includes a front frame 100, an engine hood, and a front bumper assembly 200. The engine hood is in a closed state that is fixed relative to the front frame 100. The front bumper assembly 200 is movably and adjustablely disposed on the front frame 100 along the X-axis direction to adjust the gap between the engine hood and the front bumper assembly 200.

[0043] The technical solution of this utility model is to movably adjust the front bumper assembly 200 along the X-axis direction to the front frame 100. In this way, the front bumper assembly 200 can be moved and adjusted along the X-axis direction towards the front frame 100. Since the hood has a fixed closed state relative to the front frame 100, the relative position of the front bumper assembly 200 and the front frame 100 in the X-axis direction can be adjusted to achieve the effect of adjusting the relative position of the front bumper assembly 200 and the hood in the X-axis direction. Thus, by moving the front bumper assembly 200, tolerances can be absorbed, and the size of the gap between the front bumper assembly 200 and the hood can be adjusted, thereby achieving the effect of controlling the gap accuracy between the front bumper 210 and the hood.

[0044] Secondly, the position of the hood does not need to be changed during the entire adjustment process, and the gap difference between the hood and the fender does not affect the gap difference. That is, the position of the front bumper assembly 200 in the X-axis direction of the car can be adjusted separately according to the actual position of the hood, so that the gap between the front bumper assembly 200 and the hood can be adjusted, making the gap adjustment between the front bumper assembly 200 and the hood convenient.

[0045] It should be noted that in this scheme, the X-axis direction refers to the front-to-back direction of the car, the Y-axis direction refers to the left-to-right direction of the car, and the Z-axis direction refers to the up-to-down direction of the car.

[0046] Optionally, the front bumper assembly 200 is provided with an adjustment hole 221, which is configured as an elongated hole extending along the X-axis. The front frame 100 is provided with a first fixing hole corresponding to the adjustment hole 221. The adjustment bolt 300 passes through the adjustment hole 221 and is connected to the first fixing hole. The width of the adjustment hole 221 along the Y-axis is adapted to the outer diameter of the adjustment bolt 300. It can be understood that the adjustment bolt 300 passes through the adjustment hole 221 and the first fixing hole. Since the width of the adjustment hole 221 along the Y-axis is adapted to the outer diameter of the adjustment bolt 300, the adjustment hole 221 can limit the displacement of the adjustment bolt 300 in the Y-axis direction. And since the adjustment hole 221 is configured as an elongated hole extending along the X-axis, it can be known that the opening direction of the adjustment hole 221 is the Z-axis direction. The adjustment bolt 300 passes through the adjustment hole 221 and is connected to the first fixing hole. The width of the adjustment hole 221 along the Y-axis is adapted to the outer diameter of the adjustment bolt 300. The adjusting bolt 300 passes through the adjusting hole 221 and the first fixing hole in the Z-axis direction, thereby restricting the displacement of the front bumper assembly 200 and the front frame 100 in the Z-axis direction. This ensures that the front bumper assembly 200 can only move in the X-axis direction. Once the front bumper assembly 200 is in the correct position, tightening the adjusting bolt 300 will secure the front bumper assembly 200 and the front frame 100. Therefore, the cooperation between the adjusting bolt 300 and the adjusting hole 221 and the first fixing hole 233 not only limits movement but also secures the assembly. Compared to solutions where the fastening and positioning structures are separate, this solution is simpler and saves on parts, thus reducing component costs and vehicle weight. Of course, this solution is not limited to this. In other embodiments, a movable groove can be provided in one of the front bumper assembly 200 and the front frame 100, and a movable rib adapted to the movable groove can be provided in the other. The length of the movable groove and the movable rib extends in the X-axis direction. When the gap between the front bumper assembly 200 and the hood is within a preset range, the front frame 100 and the front bumper assembly 200 are fixed by a fixing structure. The fixing structure can be a screwed structure or a welded structure, etc.

[0047] Optionally, the front bumper assembly 200 includes a front bumper 210 and an anti-submersion bracket 220 fixed to the front bumper 210. The anti-submersion bracket 220 overlaps the front frame 100, and an adjustment hole 221 is provided on the anti-submersion bracket 220. It can be understood that since the anti-submersion bracket 220 is fixed on the front bumper 210 and overlaps the front frame 100, the height between the front bumper 210 and the front frame 100 can be guaranteed. Since the hood has a fixed closed state relative to the front frame 100, the surface difference between the front bumper 210 and the hood can be guaranteed.

[0048] Since the adjustment hole 221 is located on the anti-submarine support 220, when the anti-submarine support 220 moves along the X-axis, it is equivalent to the front bumper assembly 200 moving along the X-axis.

[0049] Furthermore, the anti-submarine support 220 is also provided with a mounting through hole 222, and the front frame 100 is also provided with a second fixing hole corresponding to the mounting through hole 222. The mounting bolt 400 passes through the mounting through hole 222 and is connected to the second fixing hole. The diameter of the mounting through hole 222 is larger than the outer diameter of the mounting bolt 400. It can be understood that, since the diameter of the mounting through hole 222 is larger than the outer diameter of the mounting bolt 400, when the anti-submarine support 220 moves along the X-axis, the adjusting bolt 300 passing through the adjusting hole 221 and the first fixing hole can... To limit the displacement of the anti-diving bracket 220 in the Y-axis and Z-axis directions, the mounting bolt 400 can move along the X-axis within the mounting hole 222. Once the front bumper assembly 200 is in the correct position, tightening the mounting bolt 400 and adjusting bolt 300 will secure the anti-diving bracket 220 and the front frame 100, thus increasing the installation stability of the front bumper assembly 200 and the front frame 100.

[0050] Multiple mounting holes 222 are provided, which are located on both sides of the adjustment hole 221 in the Y-axis direction. This can improve the installation stability of the front bumper assembly 200 and the front frame 100, while also increasing the stability of the front bumper assembly 200 moving in the X-axis direction, and preventing the front bumper assembly 200 from tilting on both sides in the Y-axis direction.

[0051] Furthermore, the anti-submersion bracket 220 includes a mounting lug that extends along the X-axis direction, and an adjustment hole 221 and a mounting through hole 222 are provided at the free end of the mounting lug.

[0052] In this embodiment, two mounting lugs are spaced apart along the Y-axis, three mounting through holes 222 are provided, and one adjustment hole 221 is provided. The adjustment hole 221 is provided on the side of one mounting lug close to the other mounting lug. One mounting hole is provided on the mounting lug with the adjustment hole 221 and is spaced apart from the adjustment hole 221 along the Y-axis. The other two mounting through holes 222 are provided on the other lug and are spaced apart along the Y-axis. This can improve the installation stability of the anti-submersion bracket 220 and the front frame 100, while further increasing the stability of the movement of the anti-submersion bracket 220.

[0053] The free end of the mounting bracket is also equipped with a weight reduction notch, which can reduce the weight of the front bumper assembly by 200, thus contributing to the lightweighting of the vehicle.

[0054] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 Furthermore, the front bumper assembly 200 also includes a center bracket 230, and the anti-diving bracket 220 is fixed to the front bumper 210 through the center bracket 230, which can improve the strength of the connection between the front bumper 210 and the anti-diving bracket 220.

[0055] It should be noted that when installing the front bumper assembly 200, first install the center bracket 230 onto the front bumper 210, then install the anti-diving bracket 220 onto the front bumper 210, and finally connect the anti-diving bracket 220 and the front frame 100.

[0056] In one embodiment, the center bracket 230 is provided with a first limiting hole 235, and the front bumper 210 is provided with a first limiting pin 211 corresponding to the first limiting hole 235. The first limiting pin 211 extends along the X-axis direction, and the width of the first limiting hole 235 along the Z-axis direction is adapted to the width of the first limiting pin 211 along the Z-axis direction. It can be understood that by providing the first limiting hole 235 on the center bracket 230 and the first limiting pin 211 corresponding to the first limiting hole 235 on the front bumper 210, and by making the width of the first limiting hole 235 along the Z-axis direction adapted to the width of the first limiting pin 211 along the Z-axis direction, the relative displacement of the center bracket 230 and the front bumper 210 in the Z-axis direction can be limited by the first limiting hole 235 and the first limiting pin 211, thereby making the installation of the center bracket 230 and the front bumper 210 simpler.

[0057] It should be noted that in this embodiment, the width of the first limiting hole 235 in the Y-axis direction is greater than the width of the first limiting pin 211 in the Y-axis direction. This allows the first limiting pin 211, when placed in the first limiting hole 235, to limit the relative position of the middle bracket 230 and the front bumper 210 in the Z-axis direction, while also allowing for fine-tuning of the displacement of the middle bracket 230 and the front bumper 210 in the Y-axis direction. This reduces the probability of the middle bracket 230 deviating from the preset installation position due to installation and manufacturing errors. Of course, this solution is not limited to this. In other embodiments, the width of the first limiting hole 235 in the Y-axis direction can also be adapted to the width of the first limiting pin 211 in the Y-axis direction.

[0058] Furthermore, the center bracket 230 is also provided with a second limiting hole 236, and the front bumper 210 is provided with a second limiting pin 212 corresponding to the second limiting hole 236. The second limiting pin 212 extends along the X-axis direction, and the second limiting hole 236 is adapted to the second limiting pin 212. It can be understood that the second limiting hole 236 is provided on the center bracket 230, and the second limiting pin 212 adapted to the second limiting hole 236 is provided on the front bumper 210, and the second limiting pin 212 extends along the X-axis direction. In this way, during installation, the second limiting pin 212 is positioned such that the second limiting hole 236 is positioned within the center bracket 230. Hole 236 is aligned with the second limiting pin 212 and moves along the X-axis toward the front bumper 210, thereby placing the second limiting pin 212 inside the second limiting hole 236. Since the second limiting hole 236 is adapted to the second limiting pin 212, the second limiting hole 236 can restrict the lateral displacement of the second limiting pin 212, that is, restrict the lateral relative displacement of the front bumper 210 and the center bracket 230. Here, lateral refers to the direction perpendicular to the X-axis direction, such as, but not limited to, the Y-axis direction and the Z-axis direction.

[0059] It should be noted that the matching of the second limiting hole 236 and the second limiting pin 212 means that the width of the second limiting hole 236 matches the width of the radial cross-section of the second limiting pin 212. That is, the width of the second limiting hole 236 in the Y-axis direction matches the width of the radial cross-section of the second limiting pin 212 in the Y-axis direction, and the width of the second limiting hole 236 in the Z-axis direction matches the width of the radial cross-section of the second limiting pin 212 in the Z-axis direction. This achieves the effect of limiting the displacement of the front bumper 210 and the center bracket 230 in the Y-axis and Z-axis directions through the second limiting hole 236 and the second limiting pin 212.

[0060] In one embodiment, the center bracket 230 and the front bumper 210 are welded. Welding involves melting the metal materials through heat conduction and fusing them with other metal materials to form a strong metal connection. This connection method creates a large contact area on the connection surfaces of the front bumper 210 and the center bracket 230, thus giving them better robustness and shock resistance. Compared to other connection methods, such as riveting and bolting, welded connections will not loosen under heavy loads, vibration, or temperature changes, effectively enhancing the structural strength and stability of the front bumper 210 and the center bracket 230. Furthermore, the welded joint can be flush with the surfaces of the center bracket 230 and the front bumper 210, and the welded joint can have various shapes to meet the needs of different structures and shapes. Simultaneously, welding can repair and improve the surfaces of the center bracket 230 and the front bumper 210, enhancing their quality and smoothness, thus making them more aesthetically pleasing. Furthermore, welding eliminates the need for drilling holes in the center bracket 230 and the front bumper 210, saving labor and time without reducing the cross-sectional area of ​​the material, ensuring full material utilization. In addition, welding typically requires no auxiliary parts, resulting in a simple connection structure and a short force transmission path, further reducing the connection cost of the center bracket 230 and the front bumper 210.

[0061] Among them, at least two first limiting holes 235 are provided, and at least one first limiting hole 235 is provided on each side of the middle bracket 230 along the Y-axis direction, which can increase the positioning effect of the middle bracket 230 and the front bumper 210 in the Z-axis direction.

[0062] The second positioning hole 224 is located approximately in the middle of the middle bracket 230 along the Y-axis direction, and is located on the lower side of the middle bracket 230 along the Z-axis direction.

[0063] In this embodiment, the middle bracket 230 is provided with a first limiting hole 235 and a second limiting hole 236. The front bumper 210 is provided with a first limiting pin 211 corresponding to the first limiting hole 235 and a second limiting pin 212 corresponding to the second limiting hole 236. During installation, the Y-axis and Z-axis directions of the front bumper 210 and the middle bracket 230 are first positioned by the cooperation of the first limiting hole 235 and the first limiting pin 211, and the second limiting hole 236 and the second limiting pin 212. Then, the front bumper 210 and the middle bracket 230 are fixed by welding. This can reduce the probability that the actual installation position of the middle bracket 230 deviates from the preset installation position. Moreover, positioning the front bumper 210 and the middle bracket 230 first and then fixing the front bumper 210 and the middle bracket 230 can reduce the installation difficulty of the middle bracket 230 and improve the installation efficiency.

[0064] Reference Figure 2 , Figure 3 , Figure 4 and Figure 7 Optionally, the anti-diving support 220 is further provided with a first positioning hole 223, and the middle support 230 is provided with a first positioning pin 231 corresponding to the first positioning hole 223. The first positioning pin 231 extends in the X-axis direction, and the width of the first positioning hole 223 in the Z-axis direction is adapted to the width of the first positioning pin 231 in the Z-axis direction. It can be understood that the first positioning hole 223 is provided on the anti-diving support 220, and the first positioning pin 231 adapted to the first positioning hole 223 is provided on the middle support 230, and the first positioning pin 231 extends in the X-axis direction. During installation, the first positioning hole 223 is aligned with the first positioning pin 231 and moves towards the middle bracket 230 along the X-axis, thereby placing the first positioning pin 231 inside the first positioning hole 223. Since the width of the first positioning hole 223 along the Z-axis matches the width of the first positioning pin 231 along the Z-axis, the first positioning hole 223 can restrict the displacement of the first positioning pin 231 in the Z-axis direction, thereby restricting the displacement of the anti-submarine bracket 220, the middle bracket 230, and the front bumper 210 in the Z-axis direction.

[0065] Furthermore, the anti-diving bracket 220 is also provided with a second positioning hole 224, and the front bumper 210 is provided with a second positioning pin 213 corresponding to the second positioning hole 224. The second positioning pin 213 extends in the Z-axis direction and is adapted to the second positioning hole 224. It can be understood that the second positioning hole 224 is provided on the anti-diving bracket 220, and the second positioning pin 213 adapted to the second positioning hole 224 is provided on the front bumper 210, and the second positioning pin 213 extends in the Z-axis direction. In this way, during installation, the second positioning pin 213 is positioned in the Z-axis direction. The positioning hole 224 is aligned with the second positioning pin 213 and moves along the Z-axis towards the front bumper 210, thereby placing the second positioning pin 213 inside the second positioning hole 224. Since the second positioning hole 224 is adapted to the second positioning pin 213, the second positioning hole 224 can limit the lateral displacement of the second positioning pin 213, that is, limit the lateral relative displacement of the front bumper 210 and the anti-submarine support 220. Here, lateral refers to the direction perpendicular to the Z-axis direction, such as, but not limited to, the Y-axis direction and the X-axis direction.

[0066] Furthermore, the anti-diving support 220 is also provided with a third positioning hole 227, and the middle support 230 is provided with a third positioning pin 232 corresponding to the third positioning hole 227. The third positioning pin 232 extends in the X-axis direction, and the third positioning hole 227 and the third positioning pin 232 are adapted to each other. It can be understood that the third positioning hole 227 is provided on the anti-diving support 220, and the third positioning pin 232 adapted to the third positioning hole 227 is provided on the middle support 230, and the third positioning pin 232 extends in the X-axis direction. In this way, during installation, the third positioning pin 232 is used to ensure that the third positioning pin 232 is properly positioned. Hole 227 is aligned with the third positioning pin 232 and moved along the X-axis towards the middle bracket 230, so that the third positioning pin 232 is placed in the third positioning hole 227. Since the third positioning hole 227 is adapted to the third positioning pin 232, the third positioning hole 227 can restrict the lateral displacement of the third positioning pin 232, that is, restrict the lateral relative displacement of the front bumper 210 and the anti-diving bracket 220. Here, lateral refers to the direction perpendicular to the X-axis direction, such as, but not limited to, the Y-axis direction and the Z-axis direction.

[0067] Optionally, the anti-diving support 220 is further provided with a first threaded hole 225, which opens in the X-axis direction. The middle support 230 is provided with a first fastening hole 233 corresponding to the first threaded hole 225. A first threaded bolt 500 passes through the first threaded hole 225 and connects to the first fastening hole 233. The diameter of the first threaded hole 225 is larger than the outer diameter of the first threaded bolt 500. It can be understood that because the diameter of the first threaded hole 225 is larger than the outer diameter of the first threaded bolt 500, when the first threaded bolt 500 passes through the first threaded hole 225 and the first fastening hole 233 in the X-axis direction, the first threaded bolt 500... It can only limit the displacement of the anti-submersion bracket 220 and the middle bracket 230 in the X-axis direction, while the anti-submersion bracket 220 can be laterally displaced relative to the middle bracket 230. The lateral displacement refers to the direction perpendicular to the X-axis, such as but not limited to the Y-axis and Z-axis directions. This allows for fine adjustment of the lateral displacement of the anti-submersion bracket 220 relative to the middle bracket 230, improving the installation accuracy of the anti-submersion bracket 220 and the middle bracket 230. When the anti-submersion bracket 220 is adjusted to the preset installation position, the first bolt 500 is tightened. This reduces the probability that the actual installation position of the anti-submersion bracket 220 deviates from the preset installation position.

[0068] Optionally, the anti-diving bracket 220 also has a second threaded hole 226, which opens in the Z-axis direction. The middle bracket 230 and the front bumper 210 are respectively provided with a second fastening hole 234 and a third fastening hole corresponding to the second threaded hole 226. The second threaded bolt 600 passes through the second threaded hole 226 and is connected to the second fastening hole 234 and the third fastening hole. The diameter of the second threaded hole 226 is larger than the outer diameter of the second threaded bolt 600. It can be understood that since the diameter of the second threaded hole 226 is larger than the outer diameter of the second threaded bolt 600, when the second threaded bolt 600 passes through the second threaded hole 226, the second fastening hole 234, and the third fastening hole in the Z-axis direction, the second threaded bolt 600 can restrict the displacement of the anti-diving bracket 220, the middle bracket 230, and the front bumper 210 in the Z-axis direction, but cannot restrict the displacement of the anti-diving bracket 220, the middle bracket 230, and the front bumper 210. The lateral displacement of the anti-submarine support 220 and the middle support 230 and the front bumper 210 is limited. The lateral displacement refers to the direction perpendicular to the Z-axis, such as but not limited to the X-axis and Y-axis directions. However, due to the cooperation between the first bolt 500 and the first bolt hole 225 and the first fastening hole 233, the displacement of the anti-submarine support 220 and the middle support 230 in the X-axis direction is restricted. In addition, the middle support 230 is fixed to the front bumper 210. Therefore, the anti-submarine support 220 can be finely adjusted relative to the middle support 230 and the front bumper 210 in the Y-axis direction, thereby improving the installation accuracy of the anti-submarine support 220, the middle support 230 and the front bumper 210. When the anti-submarine support 220 is adjusted to the preset installation position and the second bolt 600 is tightened, the probability of the actual installation position of the anti-submarine support 220 deviating from the preset installation position can be reduced.

[0069] The second bolt 600 passes through the second bolt hole 226 and is connected to the second fastening hole 234 and the third fastening hole. In this way, the anti-diving bracket 220, the middle bracket 230 and the front bumper 210 can be fixed together as a whole by the second bolt 600, which can increase the installation stability of the anti-diving bracket 220, the middle bracket 230 and the front bumper 210.

[0070] It should be noted that "corresponding" in this solution refers to the matching relationship between the two. For example, the above-mentioned "the middle support 230 is provided with a first fastening hole 233 corresponding to the first screw hole 225" means that the first screw hole 225 and the first fastening hole 233 can both be used by the first screw bolt 500 during assembly, thereby realizing the connection function between the middle support 230 and the anti-submersion support 220.

[0071] In this embodiment, the first threaded bolt 500 is engaged with the first threaded hole 225 and the first fastening hole 233 for a tight-fitting positioning engagement; the second threaded bolt 600 is engaged with the second threaded hole 226, the second fastening hole 234 and the third fastening hole for a tight-fitting positioning engagement; the first positioning hole 223 is engaged with the first positioning pin 231; the second positioning hole 224 is engaged with the second positioning pin 213; and the third positioning hole 227 is engaged with the third positioning pin 232. This allows for the positioning and fixing of the anti-diving bracket 220, the middle bracket 230 and the front bumper 210 in the X-axis, Y-axis and Z-axis directions. This increases the installation stability of the anti-diving bracket 220, the middle bracket 230 and the front bumper 210 while reducing the probability that the actual installation position of the anti-diving bracket 220 deviates from the preset installation position.

[0072] It should be noted that the first bolt 500 and the second bolt 600 not only serve to secure the installation, but also to position the installation, thus improving the effectiveness of the installation and the accuracy of the installation position.

[0073] In this embodiment, there are two first positioning holes 223, which are respectively located on both sides of the anti-submersion bracket 220 in the Y-axis direction, so as to better position the displacement of the anti-submersion bracket 220 in the Z-axis direction.

[0074] Furthermore, the anti-submersion bracket 220 is provided with a positioning and mounting part extending in the Y-axis direction, and the first screw hole 225 and the first positioning hole 223 are spaced apart on the positioning and mounting part along the Y-axis direction.

[0075] There are two positioning and mounting parts, which are located on both sides of the anti-submersion bracket 220 in the Y-axis direction. Each positioning and mounting part has a first screw hole 225 and a first positioning hole 223.

[0076] Multiple second screw holes 226 are provided, and the multiple second screw holes 226 are spaced apart along the Y-axis on the anti-submarine bracket 220. This can increase the stability of the anti-submarine bracket 220, the middle bracket 230 and the front bumper 210 during installation.

[0077] It should be noted that the first positioning pin 231, the second positioning pin 213, the third positioning pin 232, the first limiting pin 211 and / or the second limiting pin 212 can be in the form of a sheet or a column. The specific shape of the first positioning pin 231, the second positioning pin 213, the third positioning pin 232, the first limiting pin 211 and / or the second limiting pin 212 is not limited here.

[0078] Furthermore, the gap between the hood and the front bumper assembly 200 is between 2.5mm and 4.5mm, which prevents the gap from being directly visible to the user from a normal visual angle, thus improving the overall refinement of the vehicle.

[0079] Optionally, the front frame 100 is equipped with a detachable assembly fixture 700. The assembly fixture 700 is used to push the front bumper assembly 200 along the X-axis towards the hood. It can be understood that by using the detachable assembly fixture 700 to push the front bumper assembly 200 along the X-axis towards the hood, and by positioning it using the assembly fixture 700, the assembly process dimensional chain between the front bumper assembly 200 and the hood can be minimized, avoiding errors from manual adjustment, thus minimizing assembly errors and increasing the accuracy of the gap adjustment between the front bumper assembly 200 and the hood. Of course, this solution is not limited to this; the front bumper assembly 200 can also be manually pushed along the X-axis towards the hood to adjust the gap width between the bumper assembly and the hood.

[0080] Reference Figure 9 and Figure 10 Furthermore, the assembly tool 700 is used to push the front bumper assembly 200 against the side near the hood. It can be understood that the gap between the front bumper assembly 200 and the hood is mainly caused by the gap between the front bumper assembly 200 and the hood. By directly using the assembly tool 700 to push the front bumper assembly 200 against the side near the hood, the accuracy of the gap adjustment between the front bumper assembly 200 and the hood can be improved.

[0081] Optionally, the assembly fixture 700 is provided with a sliding mechanism 710. The sliding mechanism 710 is provided with a sliding seat 711 and a gap block 712. The sliding seat 711 is provided with an adjustment recess 711a. The gap block 712 is slidably disposed in the adjustment recess 711a along the X-axis direction. The gap block 712 has a protrusion that protrudes laterally from the sliding seat 711. The side of the protrusion facing the sliding seat 711 is provided with an abutting recess 712a for abutting the hood. The side of the sliding seat 711 away from the gap block 712 is provided with a pushing recess 711b facing the gap block 712 for pushing the front bumper assembly 200. It can be understood that such a sliding mechanism 710 has a simple structure and is easy for the operator to control the assembly fixture 700, thereby increasing the efficiency of gap adjustment between the front bumper assembly 200 and the hood.

[0082] It is understandable that once the gap between the current bumper assembly 200 and the hood is adjusted, the assembly fixture 700 will be removed. This will reduce the weight of the car and help achieve lightweighting.

[0083] Furthermore, multiple sliding mechanisms 710 are provided, and the multiple sliding mechanisms 710 are spaced apart along the Y-axis direction. This can increase the uniformity of force on the front bumper assembly 200 and reduce the risk of the front bumper assembly 200 tilting or even deforming when pushed.

[0084] In this embodiment, there are three sliding mechanisms 710, which are spaced apart along the Y-axis. In other embodiments, there may be four or six sliding mechanisms 710. The specific number of sliding mechanisms 710 is not limited here.

[0085] The sliding mechanism 710 also includes adjustable shims. The relative dimensions of the gap block 712 and the sliding seat 711 are ensured by the adjustable shims. The position of the sliding mechanism 710 in the X-axis direction is aligned by the outer contour of the engine hood.

[0086] The assembly fixture 700 also includes a locking component 720. After the gap block 712 contacts the outer contour of the engine hood, the sliding mechanism 710 is fixed by the locking component 720, the front bumper assembly 200 is pushed to fit the sliding seat 711, and then the adjusting bolt 300 is tightened.

[0087] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
