Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and in particular to a front bumper reinforcement structure. Furthermore, this invention also relates to a vehicle having this front bumper reinforcement structure. Background Technology

[0002] The non-load-bearing body is flexibly connected to the frame via rubber pads or springs. The frame is the foundation supporting the entire vehicle, bearing the various loads of the assemblies mounted on it. The body only bears the weight of the passengers and cargo; its auxiliary role in load-bearing the frame is not considered in the frame design. Besides the cushioning and shock absorption provided by the tires and suspension system, the flexible rubber pads also provide auxiliary cushioning, appropriately absorb torsional deformation of the frame, and reduce noise, thus extending the vehicle's lifespan and improving ride comfort. The chassis and body can be assembled separately and then combined, simplifying the assembly process and facilitating specialized collaboration.

[0003] The front bumper is mounted at the front of the vehicle and consists of the bumper frame and body panel. As a crucial anti-collision structure, the strength and stability of the front bumper's installation are paramount. However, due to an unreasonable design and connection method between the front bumper and the vehicle body, the connection stability is poor when installed. Especially when driving on bumpy roads, the front bumper is prone to swaying, which not only generates abnormal noises affecting comfort but also makes it susceptible to significant deformation in the event of a collision, thus compromising vehicle safety. Summary of the Invention

[0004] In view of this, the present invention aims to provide a front bumper reinforcement structure to improve the installation firmness and collision safety of the front bumper.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A front bumper reinforcement structure includes a bumper reinforcement bracket disposed at the rear end of the front bumper, and a connecting frame connecting the front end of the bumper reinforcement bracket to the front anti-collision beam; the bumper reinforcement bracket is arranged along the left-right direction of the vehicle, and one end of the bumper reinforcement bracket is connected to the energy-absorbing box connecting plate, and the other end is connected to the front bumper in the front-rear direction of the vehicle.

[0007] Furthermore, the connecting frame is tilted outwards from the rear of the vehicle.

[0008] Furthermore, the connecting frame includes a tubular body and connecting plates provided at both ends of the tubular body; the connecting plate at one end of the tubular body is connected to the bumper reinforcement bracket, and the connecting plate at the other end is connected to the front anti-collision beam.

[0009] Furthermore, the bottom of the bumper reinforcement bracket has a first connecting end that connects to the front bumper, and the first connecting end is arranged in a triangle with the two connecting plates; and / or, the bumper reinforcement bracket has a second connecting end that connects to the energy-absorbing box connecting plate, and the second connecting end is arranged in a triangle with the two connecting plates.

[0010] Furthermore, the top of the end of the bumper reinforcement bracket connected to the front bumper is provided with a sub-bracket; the sub-bracket protrudes towards the rear of the vehicle, and the sub-bracket is connected to the front bumper in the longitudinal direction of the vehicle.

[0011] Furthermore, the sub-bracket includes a main body and two side portions arranged opposite to each other on the upper and lower sides of the main body; the main body is connected to the front bumper.

[0012] Furthermore, the top of the bumper reinforcement bracket has an extension portion extending toward the rear of the vehicle; the extension portion is supported at the bottom of the front bumper, one of its side portions is supported at the bottom of the extension portion and connected to the extension portion, and the other side portion has a first flange, the first flange being connected to the bumper reinforcement bracket.

[0013] Furthermore, the bumper reinforcement bracket is provided with a mudguard bracket extending towards the rear of the vehicle, and the mudguard bracket is connected to the mudguard in the front-rear direction of the vehicle.

[0014] Furthermore, the edge of the bumper reinforcement bracket is provided with a second flange; and / or, the bumper bracket is provided with a reinforcing protrusion.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The front bumper reinforcement structure described in this invention connects one end of the bumper reinforcement bracket to the energy-absorbing box connecting plate, and the other end to the front bumper in the front-rear direction of the vehicle. A connecting frame is also connected between the bumper reinforcement bracket and the front anti-collision beam. This not only improves the installation firmness of the front bumper, but also disperses and transfers the side impact force borne by the front bumper to the energy-absorbing box and the front anti-collision beam, thereby improving collision safety.

[0017] Furthermore, the connecting bracket is tilted outwards, allowing the connecting bracket, bumper reinforcement bracket, and body longitudinal beams to be arranged in a roughly triangular pattern. This leverages the high stability of triangles to further enhance the bumper's installation security. The connecting bracket includes a tubular main body, providing good rigidity. Connecting plates at both ends of the tubular main body facilitate connection between the connecting bracket and the bumper reinforcement bracket and front anti-collision beam. The triangular arrangement between the first connecting end and the two connecting plates, and the triangular arrangement between the second connecting end and the two connecting plates, both utilize the stability of triangles to further improve the bumper's installation security and the dispersion and transmission of collision forces. The sub-bracket further enhances the connection strength of the front bumper in the longitudinal direction of the entire vehicle.

[0018] Secondly, the main body and side sections have a simple structure, making them easy to process and shape, facilitating the connection between the sub-support and the front bumper, and providing good connection strength. The extension section is supported on the front bumper, with one side of its portion supported at the bottom of the extension section. This enhances the connection strength between the bumper reinforcement bracket and the sub-support and the front bumper, thereby improving the support effect on the front bumper and effectively preventing the front bumper from swaying in the vertical direction of the vehicle.

[0019] Furthermore, by setting up mudguard brackets, mounting points can be provided for mudguard installation, while also limiting the mudguard's displacement in the lateral direction of the vehicle, thus preventing mudguard wobbling. The second flange and reinforcing protrusion both contribute to improving the structural strength of the bumper reinforcement bracket, thereby increasing the installation strength of the front bumper.

[0020] Meanwhile, another objective of the present invention is to provide a non-load-bearing vehicle body, wherein the non-load-bearing vehicle body is provided with the front bumper reinforcement structure as described above.

[0021] The vehicle body described in this invention has the same beneficial effects as the aforementioned front bumper reinforcement structure, and will not be repeated here. Attached Figure Description

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0043] In the description of this invention, it should be noted that the directional terms used in this embodiment, such as "up," "down," "left," "right," "front," and "rear," are defined based on the vehicle's vertical, horizontal, and longitudinal directions. Specifically, the vehicle's vertical direction is also the vehicle's height direction (Z-direction), the vehicle's longitudinal direction is also the vehicle's length direction (X-direction), and the vehicle's horizontal direction is also the vehicle's width direction (Y-direction).

[0044] Furthermore, in the description of this invention, unless otherwise explicitly defined, the terms "installation," "connection," "linking," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This embodiment relates to a front bumper reinforcement structure. In terms of overall structure, the bumper reinforcement structure includes a bumper reinforcement bracket 2 disposed at the rear end of the front bumper 1, and a connecting frame 4 connecting the front end of the bumper reinforcement bracket 2 to the front anti-collision beam 105. The bumper reinforcement bracket 2 is arranged along the left-right direction of the vehicle, with one end connected to the energy-absorbing box connecting plate 301, and the other end connected to the front bumper 1 in the front-rear direction of the vehicle.

[0047] Based on the above overview, an exemplary structure of the front bumper reinforcement structure described in this embodiment is as follows: Figures 1 to 3 As shown in the figure. Considering that the front bumper reinforcement structure is symmetrically arranged on the left and right sides of the vehicle, only the part of the structure on the left side of the vehicle is shown in the figure to highlight the bumper reinforcement structure. Similar to the prior art, the front bumper 1 in this embodiment includes a frame 101 and a skin 102 disposed on the outside of the frame 101, and the bumper reinforcement bracket 2 is specifically connected to the frame 101. Here, the connection method of the frame 101 and the skin 102 can refer to the prior art.

[0048] In this embodiment, the bumper reinforcement bracket 2 is plate-shaped, with a simple structure and easy processing. As a preferred embodiment, the bumper reinforcement bracket 2 is snap-fitted to the front bumper 1 in the front-rear direction of the vehicle. Figure 1 and Figure 7 As shown, the bumper reinforcement bracket 2 has a snap-fit ​​hole 209, and the frame 101 has a plastic clip 104. The connection between the outer end of the bumper reinforcement bracket 2 and the frame 101 is achieved by snapping the plastic clip 104 into the snap-fit ​​hole 209. To improve the snap-fit ​​efficiency between the plastic clip 104 and the snap-fit ​​hole 209, the frame 101 also has a positioning post 103 extending towards the rear of the vehicle, and the bumper reinforcement bracket 2 has a positioning hole 208 for inserting the positioning post 103.

[0049] In this embodiment, the bumper reinforcement bracket 2 in the snap-fit ​​state can abut against the frame 101 in the front-rear direction of the vehicle, thereby preventing the front bumper 1 from swaying in the front-rear direction of the vehicle and providing good connection strength. It also helps reduce abnormal noise caused by the bumper reinforcement bracket 2 swaying and impacting the frame 101. Of course, in this embodiment, the positions of the plastic clip 104 and the snap-fit ​​hole 209, as well as the positioning post 103 and the positioning hole 208, can be interchanged, as long as the usage requirements are met. In addition to using the plastic clip 104, other snap-fit ​​structures that can engage with the snap-fit ​​hole 209 can also be used.

[0050] like Figures 1 to 4 As shown, in this embodiment, the energy-absorbing box connecting plate 301 is connected to the vehicle frame, which has a longitudinal beam 9 located in the middle of the vehicle and extending along the longitudinal direction of the vehicle. The energy-absorbing box connecting plate 301 extends along the left-right direction of the vehicle and is connected to the front end of the longitudinal beam 9. The energy-absorbing box 3 is connected between the forward-facing side of the energy-absorbing box connecting plate 301 and the front bumper beam 105. To facilitate the connection between the longitudinal beam 9, the energy-absorbing box connecting plate 301, and the energy-absorbing box 3, a first connecting flange with an outward fold is provided at the front end of the longitudinal beam 9. The energy-absorbing box connecting plate 301 is connected to the longitudinal beam 9 by bolts passing through itself and the first connecting flange, and nuts screwed to the bolts. Preferably, the number of bolts and nuts used to connect the energy-absorbing box 3 and the energy-absorbing box connecting plate 301 are four each. Of course, in specific implementations, the number of bolts can be increased or decreased accordingly.

[0051] like Figure 1 , Figure 5 and Figure 8As shown, the inner end of the bumper reinforcement bracket 2 has a connecting portion extending into the vehicle along its length, which connects to the energy-absorbing box connecting plate 301. To facilitate the connection between the inner end of the bumper reinforcement bracket 2 and the energy-absorbing box connecting plate 301, the connecting portion is stacked with the energy-absorbing box connecting plate 301 in the longitudinal direction of the vehicle. Simultaneously, the connecting portion has three first connecting holes 206 arranged in a triangular pattern for better connection strength. The energy-absorbing box connecting plate 301 has first connecting mating holes corresponding to the first connecting holes 206. Bolts pass through the first connecting holes 206 and the corresponding first connecting mating holes and are screwed into the nuts, thus achieving the connection between the inner end of the bumper reinforcement bracket 2 and the energy-absorbing box connecting plate 301. The nuts here can be projection-welded nuts provided on the energy-absorbing box connecting plate 301. Of course, the number of first connecting holes 206 and first connecting mating holes can be increased or decreased according to usage requirements, in addition to the three shown in the figure.

[0052] In this embodiment, the bumper reinforcement bracket 2 is located between the rear end of the front bumper 1 and the energy-absorbing box connecting plate 301, which helps to improve the installation firmness of both ends of the front bumper 1 and enhance the durability of both ends of the front bumper 1, thereby meeting the off-road usage requirements of the vehicle.

[0053] As a preferred implementation method, such as Figure 2 and Figure 5 As shown, two second connecting flanges 204 folding towards the rear of the vehicle are provided at the middle of the bottom end of the bumper reinforcement bracket 2. The two second connecting flanges 204 are spaced apart along the left-right direction of the vehicle. The extension direction of the second connecting flanges 204 helps to guide the impact force on the bumper reinforcement bracket 2 from the bottom to the rear. The second connecting flanges 204 located near the longitudinal beam 9 are connected by bolts passing through themselves and the skin 102, and nuts screwed to the bolts. The second connecting flanges 204 located away from the longitudinal beam 9 are connected by bolts passing through themselves, the frame 101, and the skin 102, and nuts screwed to the bolts. By setting the second connecting flanges 204, not only can the structural strength of the bumper reinforcement bracket 2 be improved, but it can also be stacked with the frame 101 and skin 102 in the vertical direction of the vehicle, thereby helping to limit the movement of the bumper bracket in the vertical direction of the vehicle. Of course, the number of second connecting flanges 204 can be increased or decreased according to the usage requirements.

[0054] To further improve the structural strength of the front bumper 1, as a preferred embodiment, such as Figure 1 , Figure 5 and Figure 7As shown, the connecting frame 4 is tilted outwards from the rear of the vehicle. By setting the connecting frame 4, it can cooperate with the bumper reinforcement bracket 2 to further improve the connection strength of the front bumper 1 in the left-right direction of the entire vehicle. Furthermore, the outward tilt of the connecting frame 4 allows the connecting frame 4, the bumper reinforcement bracket 2, and the longitudinal beam 9 to be arranged in a roughly triangular pattern, utilizing the high stability of triangles to further improve the installation stability of the bumper. In addition, the setting of the connecting frame 4 creates a trapezoidal force transmission channel between the connecting frame 4, the bumper reinforcement bracket 2, the energy-absorbing box 3, and the front anti-collision beam 105. This not only provides high structural strength and stability but also facilitates the dispersion and transmission of collision forces on the front bumper 1.

[0055] like Figure 5 and Figure 7 As shown in the diagram, the connecting frame 4 in this embodiment includes a tubular body 401 and connecting plates at both ends of the tubular body 401. One connecting plate at one end of the tubular body 401 is connected to the bumper reinforcement bracket 2, and the other connecting plate is connected to the front anti-collision beam 105. The tubular body 401 provides good rigidity to the connecting frame 4. The connecting plates at both ends of the tubular body 401 facilitate connection between the connecting frame 4 and the bumper reinforcement bracket 2 and the front anti-collision beam 105. For clarity, the connecting plate connected to the front anti-collision beam 105 is referred to as the front connecting plate 402, and the connecting plate connected to the bumper reinforcement bracket 2 is referred to as the rear connecting plate 403. The front connecting plate 402 and the rear connecting plate 403 extend along the left-right direction of the vehicle, and their extension directions are opposite. The rear connecting plate 403 is connected to the bumper reinforcement bracket 2, and the front connecting plate 402 is connected to the front anti-collision beam 105.

[0056] In specific implementation, the front connecting plate 402 abuts against the front side of the front bumper beam 105 and is connected together by bolts passing through the front connecting plate 402 and the front bumper beam 105, and nuts screwed into the bolts. The rear connecting plate 403 abuts against the front side of the bumper reinforcement bracket 2. To facilitate the connection between the rear connecting plate 403 and the bumper reinforcement bracket 2, a third connecting hole 207 is provided on the bumper reinforcement bracket 2, and a third connecting mating hole is provided on the rear connecting plate 403. The rear connecting plate 403 and the bumper reinforcement bracket 2 are connected together by bolts passing through the third connecting hole 207 and the third connecting mating hole, and nuts screwed into the bolts. In addition, the wall thickness of the tubular body 401 is preferably 1.5 to 3 mm, for example, 2 mm, which provides high structural strength and is easy to arrange and implement. In this embodiment, the structure of the tubular body 401 and the connecting plates at both ends is simple, has high structural strength, and is easy to arrange and implement.

[0057] As a preferred implementation method, such as Figure 7As shown, the bottom of the bumper reinforcement bracket 2 has a first connecting end that connects to the front bumper 1, and the first connecting end and the connecting plate are arranged in a triangle. The two second connecting flanges 204 constitute this first connecting end, and one of the second connecting flanges 204, the front connecting plate 402, and the rear connecting plate 403 can be arranged in a triangle along the vehicle's height direction. The other second connecting flange 204, the front connecting plate 402, and the rear connecting plate 403 can also be arranged in a triangle along the vehicle's height direction. This utilizes the stability of the triangle to enhance the installation firmness of the front bumper 1. At the same time, the triangular arrangement also facilitates the dispersion and transmission of collision force between the bumper reinforcement bracket 2 and the connecting bracket 4 along the vehicle's front-to-back, left-to-right, and up-down directions to the front anti-collision beam 105, the energy-absorbing box 3, and the vehicle frame, thus achieving a better force dispersion effect.

[0058] Still refer to Figure 7 As shown, in this embodiment, the bumper reinforcement bracket 2 has a second connecting end that connects to the energy-absorbing box connecting plate 301, and the second connecting end is arranged in a triangle with the two connecting plates. This second connecting end is also the aforementioned connecting portion. Figure 7 As shown, the centers of the three first connecting holes 206 on the connecting part are arranged in a triangle with the two connecting plates in the horizontal direction. Furthermore, each of the first connecting holes 206 on the connecting part is arranged in a triangle with each of the two connecting plates. This triangular arrangement not only strengthens the installation stability of the front bumper 1, but also facilitates the dispersion and transmission of collision force between the bumper reinforcement bracket 2 and the connecting frame 4 along the front-rear and left-right directions of the vehicle, until it is transmitted to the front anti-collision beam 105, the energy-absorbing box 3, and the vehicle frame, thus achieving a better force dispersion effect.

[0059] In a preferred embodiment, a sub-bracket 5 is provided at the top of the end of the bumper reinforcement bracket 2 that is connected to the front bumper 1. The sub-bracket 5 protrudes towards the rear of the vehicle and is connected to the front bumper 1 in the longitudinal direction of the vehicle. By providing the sub-bracket 5, the connection strength between the front bumper 1 and the bumper reinforcement bracket 2 in the longitudinal direction of the vehicle is further improved.

[0060] Specifically, such as Figure 6 and Figure 9As shown, the sub-support 5 includes a main body 501 and two side portions arranged opposite each other on the upper and lower sides of the main body 501. The main body 501 is connected to the front bumper 1, thus making the sub-support 5 U-shaped, which is not only simple in structure but also has high strength. For ease of description, the side portion located at the top is referred to as the upper side portion 502, and the side portion located at the bottom is referred to as the lower side portion 503. The main body 501 and the side portions have a simple structure, are easy to process and form, facilitate the connection between the sub-support 5 and the front bumper 1, and have good connection strength.

[0061] Still combined Figure 6 and Figure 9 As shown, the main body 501 has a second connecting hole 506, and the frame 101 has a second connecting mating hole. The main body 501 and the frame 101 are connected together by bolts passing through the second connecting hole 506 and the second connecting mating hole, and by nuts screwed into the bolts. This helps to further strengthen the connection of the bumper reinforcement bracket 2 in the front-rear direction of the vehicle, thereby improving the installation strength of the front bumper 1.

[0062] In a preferred embodiment, the top of the bumper reinforcement bracket 2 has an extension portion 201 extending towards the rear of the vehicle. The extension portion 201 is supported at the bottom of the front bumper 1. An upper side portion 502 is supported at the bottom of the extension portion 201 and connected to it. The lower side portion 503 has a first flange 505, which is connected to the bumper reinforcement bracket 2. The first flange 505 abuts against the rear side of the bumper reinforcement bracket 2 and is welded to it.

[0063] like Figure 6 , Figure 8 and Figure 9 As shown, a third connecting flange 107 is provided on the frame 101 at the top of the outer end of the bumper reinforcement bracket 2, and a fourth connecting flange 106 is provided on the skin 102 overlapping the top of the third connecting flange 107. The third connecting flange 107 and the fourth connecting flange 106 are fixed together by bolts provided along the height direction of the vehicle and by a threaded connection between a spring nut provided on the third connecting flange 107. The extension portion 201 is supported at the bottom of the third connecting flange 107. The extension portion 201 is located between the third connecting flange 107 and the upper side portion 502 in the vertical direction of the vehicle, which helps to further prevent the front bumper 1 and the bumper reinforcement bracket 2 from moving in the vertical direction of the vehicle, thereby improving the support effect of the front bumper 1 and effectively preventing the front bumper 1 from swaying in the vertical direction of the vehicle.

[0064] like Figure 6 and Figure 9As shown in the figure, the bottom of the upper side portion 502 in this embodiment is provided with a downward-folding third flange 504, and the outer side of the third flange 504 abuts against the frame 101 in the installed state. Through the abutment between the upper side portion 502 and the extension portion 201, the connection between the first flange 505 and the bumper reinforcement bracket 2, and the abutment between the third flange 504 and the frame 101, the installation of the sub-bracket 5 and the bumper reinforcement bracket 2 in the vertical and horizontal directions of the vehicle can be limited, thereby improving the connection strength between the sub-bracket 5 and the bumper reinforcement bracket 2, as well as between the two and the frame 101.

[0065] In this embodiment, the sub-bracket 5, through the main body 501 and the first flange 505, can prevent the bumper reinforcement bracket 2 and the front bumper 1 from swaying in the front-rear direction of the vehicle. The upper side part 502 can prevent the bumper reinforcement bracket 2 and the front bumper 1 from swaying upward in the vertical direction of the vehicle. The third flange 504 can also prevent the bumper reinforcement bracket 2 and the front bumper 1 from swaying outward in the left-right direction of the vehicle, thereby improving the connection firmness of the bumper reinforcement bracket 2 and the front bumper 1.

[0066] Furthermore, to further improve the structural strength of the bumper reinforcement bracket 2, a second flange 210 is provided on the edge of the bumper reinforcement bracket 2, and a reinforcing protrusion 205 is also provided on the bumper bracket 2. In specific implementation, as a preferred arrangement, such as... Figure 9 As shown, the second flange 210 is provided on all edges of the entire bumper reinforcement bracket 2 except for the extension portion 201, and there are multiple reinforcing protrusions 205.

[0067] Preferably, one of the reinforcing protrusions 205 is located at the center of the bumper reinforcement bracket 2 in the height direction and extends along the left-right direction of the vehicle. This reinforcing protrusion 205 helps to improve the structural strength of the bumper reinforcement bracket 2 in the left-right direction of the vehicle, thereby improving the force transmission effect of the collision force in the left-right direction of the vehicle. In addition, corresponding to each second connecting flange 204, two reinforcing protrusions 205 extending from bottom to top are also provided on the bumper reinforcement bracket 2. These two reinforcing protrusions 205 can improve the structural strength of the bumper reinforcement bracket 2 in the vertical direction of the vehicle, thereby improving the force transmission effect of the collision force in the vertical direction of the vehicle.

[0068] In addition, in this embodiment, the second flange 201 can improve the structural strength of the bumper reinforcement bracket 2, making it less prone to deformation when bearing external forces, thus exhibiting higher structural strength and stability. It should be noted that the second flange 210 is only provided on a portion of the edge of the bumper reinforcement bracket 2; either the second flange 210 or the reinforcing protrusion 205 can be used, and this is a feasible approach. Furthermore, the number, shape, and extension direction of the reinforcing protrusions 205 can be customized according to usage requirements.

[0069] Still refer to Figure 8 As shown in the diagram, the bumper reinforcement bracket 2 in this embodiment is also provided with multiple weight-reducing holes 202 to reduce the overall weight, thereby reducing production costs. Furthermore, a fourth flange 203 is provided at the edge of the weight-reducing hole 202 to improve the structural strength at the weight-reducing hole 202 and facilitate processing and forming.

[0070] In a preferred embodiment, one weight-reducing hole 202 is located below the reinforcing protrusion 205 extending along the left-right direction of the vehicle, and this weight-reducing hole 292 extends along the left-right direction of the vehicle. The other weight-reducing hole 202 is located above one of the reinforcing protrusions 205 extending along the vertical direction of the vehicle, and this weight-reducing hole 202 also extends along the vertical direction of the vehicle. Both weight-reducing holes 202 are shaped to fit the spatial form of their respective locations, which helps ensure the structural strength of the bumper reinforcement bracket 2 and also reduces weight, thus providing good practicality. Of course, the position, shape, and specifications of the weight-reducing holes 202 can be determined according to usage requirements.

[0071] In a preferred embodiment, the bumper reinforcement bracket 2 is provided with a mudguard bracket 6 extending towards the rear of the vehicle. The mudguard bracket 6 is connected to the mudguard 7 in the longitudinal direction of the vehicle. By providing the mudguard bracket 6, an installation point can be provided for the mudguard 7, and the displacement of the mudguard 7 in the lateral direction of the vehicle can be limited, thereby preventing the mudguard 7 from shaking and deforming.

[0072] In specific implementation, refer to Figure 1 , Figure 5 as well as Figure 10 As shown, the front end of the mudguard bracket 6 has a front flange 601, and the rear end of the mudguard bracket 6 has a rear flange 602. The front flange 601 abuts against the rear side of the bumper reinforcement bracket 2 and is welded to the bumper reinforcement bracket 2. The rear flange 602 abuts against the top of the mudguard 7, and the two are connected together by a snap fastener 701. The bottom of the mudguard 7 is connected to the frame 101 by bolts and nuts. The structure of the front flange 601 and the rear flange 602 is simple, easy to process and form, and also facilitates the connection with the bumper reinforcement bracket 2 and the mudguard 7.

[0073] In addition, such as Figure 1 As shown, the front end of the splash guard assembly 8 on the vehicle is connected via bolts passing through itself and the mudguard 7, and nuts screwed into the bolts. The mudguard bracket 6 here provides a base for the installation of the mudguard 7 and the splash guard assembly 8, and has high connection strength. In a preferred embodiment, the front flange 601 and the rear flange 602 extend in opposite directions, making the mudguard bracket 6 Z-shaped, which further improves the robustness of the mudguard bracket 6 in the connected state.

[0074] In addition, the front end of the mudguard 7 and the rear end of the connecting frame 4 are respectively located on the front and rear sides of the bumper reinforcement bracket 2, and are spaced apart in the left and right direction of the whole vehicle. This arrangement makes the mudguard bracket 6 and the connecting frame 4 serve as the force transmission paths of the bumper reinforcement bracket 2, which is conducive to the dispersion and transmission of collision force.

[0075] In this embodiment, when the front bumper reinforcement structure receives the side impact force, the outer end of the front bumper 1 first transmits the impact force to the bumper reinforcement bracket 2, so that the impact force is transmitted from the outside to the inside along the left-right direction of the vehicle to the energy absorption box 3 and the longitudinal beam 9, and the impact force is dispersed and transmitted through the energy absorption box and the longitudinal beam 9. At the same time, the bumper reinforcement bracket 2 also disperses and transmits the impact force to the front anti-collision beam 105 through the connecting bracket 4, and then disperses and transmits the impact force to the mudguard 7 and the splash pad assembly 8 through the sub-bracket 5 and the mudguard bracket 6, respectively, so that the impact force is dispersed and transmitted to the rear of the vehicle, thereby reducing the damage of the side impact force to the front bumper 1 and improving the durability of the front bumper 1.

[0076] In this embodiment, the front bumper reinforcement structure connects one end of the bumper reinforcement bracket 2 to the energy-absorbing box connecting plate 301 and the other end to the front bumper 1 in the front-rear direction of the vehicle. The connecting bracket 4 connects the bumper reinforcement bracket 2 and the front anti-collision beam 105. This not only improves the installation firmness of the front bumper 1, but also disperses and transmits the side impact force borne by the front bumper 1 to the energy-absorbing box 3 and the front anti-collision beam 105, thereby improving the collision safety of the front bumper 1.

[0077] Furthermore, this embodiment also relates to a non-load-bearing vehicle body, which is equipped with the aforementioned front bumper reinforcement structure. The non-load-bearing vehicle body described in this embodiment has the same beneficial effects as the aforementioned front bumper reinforcement structure, and will not be repeated here.

[0078] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
