[0002] As the front face of the vehicle, the bumper structure has extremely high appearance requirements. The factory requires that the appearance should not have defects such as large gaps, uneven surfaces, and misaligned feature lines. At the same time, due to regulatory requirements such as pedestrian protection, the bumper structure and fenders need to be structurally weakened and need to be sufficiently "soft". Therefore, the difficulty of controlling the appearance size of the vehicle bumper structure has increased significantly.

[0003] In the related art, during the process of matching the bumper structure with the fender, the bumper structure and the fender are matched by a bracket.

[0050] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a bumper structure in an embodiment of the present application is shown. Figure 2 Shows Figure 1A partial enlarged view of point A in the middle. The bumper structure 1 provided in one embodiment of the present application includes a bumper 11 and a bracket assembly 12. The bumper 11 is provided with a first through hole; the bracket assembly 12 includes a bracket 121, a fastener 122 and a connector 123; the bracket 121 is provided with a second through hole; the fastener 122 includes a fastening body and a head, the fastening body is connected to the head, the fastening body is used to penetrate the second through hole and the first through hole, connect the bracket 121 and the bumper 11, and the head is used to clamp the bracket 121 and one side of the bumper 11; the connector 123 is used to connect the bracket 121 and the external fender 2; when the fastening body penetrates the second through hole and the first through hole, the external force drives the bumper 11 to deform.

[0051] The bumper 11 is connected to the bracket 121 by the fastener 122 to form the bumper structure 1, and then the bumper structure 1 is connected to the fender 2 by the connector 123, thereby achieving connection among the bumper 11, the bracket 121 and the fender 2.

[0052] It should be noted that the bumper 11, as the front face of the vehicle, has extremely high requirements for appearance. At the same time, due to regulatory requirements such as pedestrian protection, the bumper 11 and the fender 2 need to be structurally weakened and need to be sufficiently "soft". Therefore, the difficulty of controlling the appearance size of the bumper 11 has increased significantly; on the other hand, with the development of vehicles, the shape of the bumper 11 has become more and more complex, and the configuration of large air ducts, complex headlight shapes, front surround cameras, active air intake grilles, and active air dams has increased, making the shape of the bumper 11 more complex. In the process of connecting the bumper 11 to the fender 2, the bracket 121 is required as a transition structure to achieve the connection between the bumper 11 and the fender 2. Since the structure of the bumper 11 is more complex, in the process of connecting the bumper 11 to the fender 2, the bracket 121 is used as a transition structure, so that the gap and surface difference between the bumper 11 and the fender 2 mainly come from the gap and surface difference between the bumper 11 and the bracket 121.

[0053] Since the present application first connects the bumper 11 and the bracket 121 during the process of installing the bumper 11 and the fender 2, and in the process of connecting, by controlling the diameter of the fastening body and the diameter of the second through hole within a certain ratio, under this size ratio, during the process of the fastening body penetrating the second through hole and the first through hole, the bumper 11 can be driven to deform by an external force, so that the shape of the bumper 11 and the bracket 121 are matched, and then the gap and face difference between the bumper 11 and the bracket 121 can be made to meet the production requirements. On the basis that the gap and face difference between the bumper 11 and the bracket 121 meet the production requirements, it can be easier to ensure that the gap and face difference between the bumper 11, the bracket 121 and the fender 2 meet the production requirements, so that the vehicle can be produced and manufactured normally.

[0054] Furthermore, since the diameter of the fastening body and the diameter of the second through hole are controlled within a certain ratio, under this size ratio, during the process of the fastening body penetrating the second through hole and the first through hole, the bumper 11 can be driven to deform by an external force, so that the bumper 11 matches the shape of the bracket 121, which can improve the gap and surface difference quality between the bumper 11 and the bracket 121, and further improve the gap and surface difference quality between the bumper 11 and the fender 2.

[0055] Similarly, since the gap and surface difference quality between the bumper 11 and the bracket 121 are improved, the gap and surface difference quality between the bumper 11 and the fender 2 are improved, the scrapping of structures such as the bumper 11, the bracket 121 and the fender 2 can be reduced, which is beneficial to the normal production and manufacturing of the vehicle.

[0056] In addition, since the shape of the bumper 11 can be adjusted in real time as needed during the installation and connection process of the bumper 11 and the bracket 121, on the one hand, the gap and surface difference between the bumper 11 and the bracket 121 can be adjusted online in real time to optimize the gap and surface difference and facilitate the adjustment of the operator; on the other hand, even if the bumper 11, the bracket 121 and the fender 2 still have a large gap and surface difference during the subsequent installation of the bracket 121 and the fender 2, the bracket 121 and the fender 2 can be directly disassembled, and the positional relationship between the bumper 11 and the bracket 121 can be readjusted by loosening the fastener 122, without the need to repair the bracket 121, thereby greatly reducing the time required for adjustment, improving the production efficiency of the vehicle, and facilitating the operation of the operator.

[0057] In addition, when the shape and shape of the bumper 11 are more complex, the present application does not need to design a bracket 121 with a more complex shape that matches the bumper 11, thereby reducing the design difficulty for designers and the installation difficulty for installers, making it easier for operators to operate.

[0058] In some embodiments, the bracket 121 is further provided with a third through hole, and the fender 2 is provided with a fourth through hole. Figure 2 , Figure 2 Shows Figure 1 A partial enlarged view of the center A. The connector 123 includes a connector body and a connector head, the connector body is connected to the connector head, the connector body is used to penetrate the third through hole and the fourth through hole, connect the bracket 121 and the fender 2, and the connector head is used to clamp the bracket 121 and one side of the fender 2; when the connector body penetrates the third through hole and the fourth through hole, the external force drives the contact surface between the bumper 11 and the bracket 121 to deform.

[0059] Specifically, in the process of installing the bumper 11 and the fender 2, the present application first connects the bumper 11 and the bracket 121, and in the process of connecting, the diameter of the fastening body and the diameter of the second through hole are controlled within a certain ratio. Under this size ratio, during the process of the fastening body passing through the second through hole and the first through hole, the bumper 11 can be driven to deform by an external force, so that the shape of the bumper 11 and the bracket 121 are matched, and then the gap and surface difference between the bumper 11 and the bracket 121 can meet the production requirements.

[0060] On the basis that the gap and face difference between the bumper 11 and the bracket 121 meet the production requirements, since the diameter of the connecting body and the diameter of the third through hole are controlled within a certain ratio, under this size ratio, during the process of the connecting body passing through the third through hole and the fourth through hole, the bumper 11 can be driven to deform by external force, so that the shapes of the bumper 11, the bracket 121 and the fender 2 match, and the gap and face difference between the bumper 11, the bracket 121 and the fender 2 can be further reduced, and finally the gap and face difference between the bumper 11, the bracket 121 and the fender 2 meet the production requirements, so that the vehicle can be produced and manufactured normally.

[0061] In addition, when the gap and surface difference between the bumper 11 and the bracket 121 meet the production requirements, but the gap and surface difference between the bumper 11, the bracket 121 and the fender 2 do not meet the production requirements, the bracket 121 and the fender 2 can be directly disassembled, and then, the third through hole and the fourth through hole are penetrated through the connecting body, and the bumper 11 is driven to deform again by external force, and the gap and surface difference between the bumper 11, the bracket 121 and the fender 2 are readjusted, so that the gap and surface difference between the bumper 11, the bracket 121 and the fender 2 meet the production requirements, and there is no need to return the bracket 121 to the factory for rework, which reduces the offline rework of the bracket 121 and facilitates the operation of the operator.

[0062] In some embodiments, there are multiple first through holes and two bracket components 12, namely a first bracket component 13 and a second bracket component 14. Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 2 Shows Figure 1 A partial enlarged view of point A in the middle. Figure 3 A structural schematic diagram of the bumper structure in one embodiment of the present application from another perspective is shown. Figure 4 Shows Figure 2 A partial enlarged view of point A in the middle. Figure 5 Shows Figure 2The first bracket assembly 13 includes a first bracket 131, a first fastener 132 and a first connector 133. The first bracket 131 is provided with a fifth through hole. The first fastener 132 includes a first fastening body and a first head. The first fastening body is connected to the first head. The first fastening body is used to penetrate the fifth through hole and one of the first through holes to connect the first bracket 131 and the bumper 11. The first head is used to clamp the first bracket 131 and one side of the bumper 11. The first connector 133 is used to connect the first bracket 131 and the fender 2. The second bracket assembly 14 includes a second bracket The second bracket 141, the second fastener 142 and the second connecting member 143, the second bracket 141 is provided with a sixth through hole, the second fastener 142 includes a second fastening body and a second head, the second fastening body is connected to the second head, the second fastening body is used to penetrate the sixth through hole and another first through hole, connect the second bracket 141 and the bumper 11, the second head is used to clamp the second bracket 141 and one side of the bumper 11; the second connecting member 143 is used to connect the second bracket 141 and the fender 2; the plane where the first bracket 131 is located is inclined with the plane where the second bracket 141 is located.

[0063] Specifically, during the installation of the bumper 11, the bracket 121 and the fender 2, a fifth through hole and one of the first through holes are penetrated through the first fastening body to connect the first bracket 131 and the bumper 11, and a sixth through hole and another first through hole are penetrated through the second fastening body to connect the second bracket 141 and the bumper 11, thereby ensuring that the gap and the surface difference between the bumper 11 and the first bracket 131 and the second bracket 141 meet the production requirements.

[0064] Furthermore, on the basis that the gap and the surface difference between the bumper 11 and the first bracket 131 and the second bracket 141 meet the production requirements, the first bracket 131 and the fender 2 are connected by the first connecting member 133, and the second bracket 141 and the fender 2 are connected by the second connecting member 143, so that the gap and the surface difference between the bumper 11, the first bracket 131 and the fender 2 meet the production requirements, and the gap and the surface difference between the bumper 11, the second bracket 141 and the fender 2 meet the production requirements.

[0065] It should be noted that due to the complex shape of the bumper 11 and the fact that the bumper 11 and the fender 2 are located at different positions on the vehicle, when connecting the bumper 11 and the fender 2, it is necessary to connect the bumper 11 and the fender 2 at multiple positions so that the bumper 11 and the fender 2 are firmly connected.

[0066] Since the plane where the first bracket 131 is located is inclined with the plane where the second bracket 141 is located, the bumper 11 and the fender 2 can be connected at multiple angles through the first bracket 131 and the second bracket 141 that are located in different planes. Therefore, on the basis that the gap and surface difference between the bumper 11 and the fender 2 meet the production requirements, a firm connection between the bumper 11 and the fender 2 can be ensured, thereby improving the stability and safety of the vehicle.

[0067] In some embodiments, there are multiple second fasteners 142 and multiple sixth through holes, and the multiple second fasteners 142 correspond one-to-one to the multiple sixth through holes, and the multiple sixth through holes correspond one-to-one to the multiple first through holes. Any second fastener 142 is used to penetrate the one-to-one corresponding sixth through holes and the first through holes to connect the second bracket 141 and the bumper 11; wherein the contact area between the second bracket 141 and the bumper 11 is greater than the contact area between the first bracket 131 and the bumper 11.

[0068] It should be noted that, due to the complex shape of the bumper 11 and the different positions of the bumper 11 and the fender 2 on the vehicle, when connecting the bumper 11 and the fender 2, it is necessary to connect the bumper 11 and the fender 2 at multiple positions to ensure a stable connection between the bumper 11 and the fender 2. However, due to the different connection positions between the bumper 11 and the fender 2, the contact area between the bumper 11 and the fender 2 is quite different.

[0069] When the contact area between the bumper 11 and the fender 2 is large, the bumper 11 needs to be connected to the fender 2 through a bracket 121 with a larger shape and size. Since there are multiple second fasteners 142 and multiple sixth through holes, multiple second fasteners 142 correspond to multiple sixth through holes one by one, and multiple sixth through holes correspond to multiple first through holes one by one, any second fastener 142 is used to penetrate the one-to-one corresponding sixth through holes and first through holes to connect the second bracket 141 and the bumper 11. The bumper 11 can be penetrated by multiple second fasteners 142. Multiple sixth through holes and first through holes are penetrated one by one, thereby improving the stability of the connection between the bumper 11 and the fender 2, and further improving the stability and safety of the vehicle.

[0070] In some embodiments, the support assembly 12 further includes a support member 124 and a stop member 125. Figure 4 , Figure 4 Shows Figure 2A partial enlarged view of point A in the middle. The support member 124 is connected between the bracket 121 and the bumper 11 to support the deformation of the bumper 11; the limit member 125 is connected between the bracket 121 and the bumper 11 to prevent the deformation of the bumper 11. Specifically, when the bumper 11 is driven to deform by an external force, since the support member 124 is connected between the bracket 121 and the bumper 11, the support member 124 can be used as a fulcrum to allow the bumper 11 to deform relative to the support member 124. On the one hand, the bumper 11 can be deformed into a desired shape relative to the support member 124 to avoid the bumper 11 from deforming into a shape and shape that is not required for production; on the other hand, the support member 124 can provide support for the bumper 11 to avoid the bumper 11 from being broken or damaged during the deformation process, thereby improving the reliability of the deformation of the bumper 11.

[0071] In addition, when the bumper 11 is deformed by an external force, since the stopper 125 is connected between the bracket 121 and the bumper 11, the stopper 125 can be used as a blocking structure to prevent the bumper 11 from deforming. On the one hand, the bumper 11 can be blocked during the deformation process and deformed into the shape and modeling required for production.

[0072] In some embodiments, there are multiple bracket assemblies 12, and the multiple bracket assemblies 12 are evenly distributed at the connection positions of the bumper 11 and the fender 2. Since the bumper 11 has a complex shape and the bumper 11 and the fender 2 are located at different positions of the vehicle, when connecting the bumper 11 and the fender 2, it is necessary to connect the bumper 11 and the fender 2 at multiple positions. Since the multiple bracket assemblies 12 are evenly distributed at the connection positions of the bumper 11 and the fender 2, the multiple connection positions of the bumper 11 and the fender 2 can be connected by the multiple bracket assemblies 12, so that the bumper 11 and the fender 2 can be firmly connected, which can improve the stability and safety of the vehicle.

[0073] In some embodiments, the fastener 122 is a bolt or a rivet. Specifically, in the process of fastening the body to penetrate the second through hole and the first through hole, since the fastener 122 is a bolt or a rivet, on the one hand, the ratio of the diameter of the bolt or the rivet to the diameter of the second through hole is 1: (1.2-1.5), and there is sufficient connection space between the bolt or the rivet and the second through hole and the first through hole. At this time, the bumper 11 can be driven to deform by an external force, so that the bumper 11 matches the shape of the bracket 121, so that the gap and the surface difference between the bumper 11 and the bracket 121 meet the production requirements; on the other hand, since the fastener 122 is a bolt or a rivet, the bumper 11, the bracket 121 and the fender 2 can be connected by bolts and nuts or riveted, thereby ensuring the tightness of the connection between the bumper 11, the bracket 121 and the fender 2, and the safety and stability of the vehicle can be guaranteed. In addition, since the fastener 122 is a bolt or a rivet, the connection between the bumper 11, the bracket 121 and the fender 2 can be simplified, which is convenient for the operator to install. At the same time, when the gap and surface difference between the bumper 11, the bracket 121 and the fender 2 do not meet the production requirements, the bumper 11, the bracket 121 and the fender 2 can be easily disassembled, which can reduce the offline rework process and improve production efficiency.

[0074] As an optional embodiment, the rivet is a blind rivet. Among them, the blind rivet is a type of rivet used for single-sided riveting, which is riveted using a special tool - a rivet gun (manual, electric, pneumatic). During riveting, the rivet core is pulled by a special rivet gun to expand the rivet body and play a riveting role. This type of rivet is particularly suitable for riveting occasions where it is inconvenient to use ordinary rivets (which must be riveted from both sides). Specifically, during the installation and connection of the bumper 11 and the bracket 121, the bumper 11, as the front face of the vehicle, has extremely high requirements for appearance. The use of blind rivets to connect the bumper 11 and the bracket 121, on the one hand, does not require nuts to be embedded on one side of the bumper 11 or the bracket 121, which can improve the appearance of the vehicle; on the other hand, since the use of blind rivets to connect the bumper 11 and the bracket 121, only one side of the bumper 11 or the bracket 121 needs to be operated, which can simplify the operation of the operator. At the same time, by only providing the blind rivets on one side of the bumper 11 or the bracket 121 , the space occupied by the components can be reduced, thereby improving the overall space utilization of the vehicle.

[0075] In some embodiments, the fastening body is a cylinder, and the ratio of the diameter of the fastening body to the diameter of the second through hole is 1:(1.2~1.5).

[0076] It should be noted that the above ratio is 1:(1.2~1.5), that is, the ratio is 1:1.2~1:1.5, that is, the minimum ratio of the diameter of the fastening body to the diameter of the second through hole is 1:1.2, and the maximum ratio of the diameter of the fastening body to the diameter of the second through hole is 1:1.5.

[0077] It should be noted that in the process of penetrating the second through hole and the first through hole in the fastening body, it is necessary to ensure that the diameter of the fastening body is smaller than the diameters of the second through hole and the first through hole so that the fastening body can penetrate the second through hole and the first through hole, otherwise the fastening body cannot penetrate the second through hole and the first through hole.

[0078] However, when the ratio of the diameter of the fastening body to the diameter of the second through hole is small, there is not enough connection space between the fastening body and the second through hole and the first through hole during the process of the fastening body penetrating the second through hole, resulting in that when the fastening body penetrates the second through hole and the first through hole, the external force cannot drive the bumper 11 to deform. When the ratio of the diameter of the fastening body to the diameter of the second through hole is large, when the fastening body penetrates the second through hole and the first through hole, the gap between the fastening body and the second through hole is large, resulting in insufficient strength when the fastening body is connected to the bracket 121 and the bumper 11, and the fastener 122 cannot normally connect the bracket 121 and the bumper 11.

[0079] Since the ratio of the diameter of the fastening body to the diameter of the second through hole is 1:(1.2~1.5), during the process of the fastening body penetrating the second through hole, there is sufficient connection space between the fastening body, the second through hole and the first through hole, and the external force can drive the bumper 11 to deform. At the same time, after the bumper 11 is adjusted to the desired shape and position, the fastening body and the head can work together to firmly connect the bracket 121 and the bumper 11.

[0080] Specifically, since the ratio of the diameter of the fastening body to the diameter of the second through hole is 1:(1.2~1.5), that is, in the process of the fastening body penetrating the second through hole and the first through hole, there is sufficient connection space between the fastening body and the second through hole and the first through hole, at this time, the bumper 11 can be driven to deform by an external force, so that the shape of the bumper 11 and the bracket 121 are matched, so that the gap and surface difference between the bumper 11 and the bracket 121 meet the production requirements.

[0081] In some embodiments, the connecting body is a cylinder, and the ratio of the diameter of the connecting body to the diameter of the third through hole is 1:(1.2-1.5). Since the ratio of the diameter of the connecting body to the diameter of the third through hole is 1:(1.2-1.5), that is, in the process of the connecting body penetrating the third through hole and the fourth through hole, there is sufficient connection space between the connecting body and the third through hole and the fourth through hole. At this time, the bumper 11 is deformed by the external force, so that the contact surface between the bumper 11 and the bracket 121 is deformed, and then matched with the shape of the fender 2, so that the gap and surface difference between the bumper 11, the bracket 121 and the fender 2 meet the production requirements.

[0082] A vehicle provided in one embodiment of the present application includes a vehicle body, a fender 2 and a bumper structure 1. Figure 6 and Figure 7 , Figure 6 A schematic structural diagram is shown in which the bumper structure and the fender are in a separated state in one embodiment of the present application. Figure 7 Shows Figure 6 A partial enlarged view of the center A. Part of the bumper structure 1 is connected to the vehicle body, and part of the bumper structure 1 is connected to the fender 2. The vehicle body is the main structure of the vehicle, used to support other parts of the vehicle, and at the same time, used to safely and reliably accommodate passengers to avoid being attacked by wind, sand, rain, snow and other weather. The bumper 11 is a safety device that absorbs and mitigates external impact and protects the front and rear parts of the vehicle body. In addition to maintaining the original protection function, the bumper 11 also pursues harmony and unity with the body shape and pursues its own lightweight. The fender 2 is the outer panel of the vehicle body that covers the wheels. It is named because the shape and position of this component on the old body resemble bird wings. According to the installation position, it is divided into the front fender 2 and the rear fender 2. The front fender 2 is installed at the front wheel, and the maximum limit space when the front wheel rotates and jumps must be guaranteed. Therefore, the designer will use the "wheel jump diagram" to verify whether the design size of the fender 2 is appropriate according to the selected tire model size.

[0083] Specifically, part of the bumper structure 1 is connected to the vehicle body, and part of the bumper structure 1 is connected to the fender 2. In the process of installing the bumper 11 and the fender 2, the bumper 11 and the bracket 121 are first connected, and in the process of connecting, the diameter of the fastening body and the diameter of the second through hole are controlled within a certain ratio. Under this size ratio, in the process of the fastening body penetrating the second through hole and the first through hole, the bumper 11 can be driven to deform by an external force, so that the bumper 11 matches the shape of the bracket 121, and then the gap and surface difference between the bumper 11 and the bracket 121 meet the production requirements, so that the vehicle can be normally produced and manufactured.

[0084] Furthermore, on the basis that the gap and face difference between the bumper 11 and the bracket 121 meet the production requirements, since the diameter of the connecting body and the diameter of the third through hole are controlled within a certain ratio, under this size ratio, during the process of the connecting body passing through the third through hole and the fourth through hole, the bumper 11 can be driven to deform by external force, so that the shapes of the bumper 11, the bracket 121 and the fender 2 match, and the gap and face difference between the bumper 11, the bracket 121 and the fender 2 can be further reduced, and finally the gap and face difference between the bumper 11, the bracket 121 and the fender 2 meet the production requirements, so that the vehicle can be produced and manufactured normally.

[0085] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
