[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.
[0034] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.
[0035] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0036] For ease of description, spatial relative terms can be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "front", "back", "facing", "height direction", "bottom", "longitudinal", "outside", "inside", "middle", "thickness direction", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will be subsequently oriented to "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include the orientation of the top and bottom. The mechanism can be oriented in addition (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.
[0037] "Small offset collision" refers to the edge of the colliding vehicle, including the left or right side of the bumper before the collision, including 40% small offset collision and 25% small offset collision, etc. The percentage refers to the overlap of the vehicle body width and the barrier. The smaller the overlap, the smaller the contact force area, and the higher the possible damage to the vehicle body and occupants. The general way to judge the quality of the vehicle body is to record and analyze the deformation of the vehicle body during and after the collision, and collect the injury values of various parts of the human body in combination with the dummy, so as to judge the body's ability to protect the occupants; "front" refers to the front direction of the vehicle, "rear" refers to the rear direction of the vehicle; "longitudinal" refers to the length direction of the vehicle.
[0038] At present, in order to improve the small offset collision performance of a vehicle, the relevant technology often meets the vehicle's small offset collision performance requirements by thickening the body sheet metal. Thickening the body sheet metal means that the weight of the entire vehicle needs to be increased, and the manufacturing cost of the entire vehicle will be increased.
[0039] In order to solve the technical problem of improving the small offset collision performance of the vehicle body without increasing the vehicle body weight and cost too much, the small offset collision structure of the vehicle body provided in the present application is provided with two reinforcements at the main path of small offset collision energy transmission (the junction of the front wheel cover and the door sill). The two reinforcements enhance the ability to withstand small offset collision energy transmission, thereby achieving the maximum absorption of small offset collision energy with minimum weight and cost investment, thereby improving the small offset collision performance of the vehicle body.
[0040] Below through Figures 1 to 6 The small offset collision structure of the embodiment of the present application is described in detail.
[0041] like Figures 1 to 6 As shown, the present application provides a small offset collision structure 30 of a vehicle body 100, wherein the vehicle body 100 includes a front wheel cover 10 and a door sill 20, wherein the front wheel cover 10 is arranged at the rear side of a front bumper 40 of the vehicle body 100, and the door sill 20 is arranged at the rear side of the front wheel cover 10, and the small offset collision structure 30 includes: two reinforcement members, wherein the two reinforcement members are respectively arranged at a side of the front wheel cover 10 facing the door sill 20, and a side of the door sill 20 facing the front wheel cover 10, and the front wheel cover 10 and the door sill 20 are connected by the two reinforcement members.
[0042] In this embodiment, the small offset collision structure 30 of the vehicle body 100 provided in the embodiment of the present application is provided with two reinforcements at the main path of small offset collision energy transmission (the junction of the front wheel cover 10 and the door sill 20). The two reinforcements enhance the ability to withstand small offset collision energy transmission, thereby achieving the maximum absorption of small offset collision energy with minimum weight and cost investment, thereby improving the small offset collision performance of the vehicle body 100.
[0043] Specifically, those skilled in the art can understand that the junction and connection point between the front wheel cover 10 and the door sill 20 are located in the main path of small offset collision energy transmission, and are also the main stress points of small offset collision energy transmission. When a small offset collision occurs to the vehicle body 100, the connection point between the front wheel cover 10 and the door sill 20 is prone to collapse. Therefore, the embodiment of the present application proposes to add two reinforcements to the weaker part of the small offset collision path L of the vehicle body 100. The two reinforcements make up for the defect of insufficient structural strength at the junction of the front wheel cover 10 and the door sill 20, thereby improving the overall small offset collision performance of the vehicle body 100.
[0044] In addition, the two reinforcements are arranged as a split structure, which can reduce the manufacturing difficulty and cost of the reinforcements compared to the reinforcements of the integrated structure. The two reinforcements can be connected to the vehicle body 100 and to each other by welding, riveting, screwing or clamping, thereby improving the connection reliability between the two reinforcements and the vehicle body 100 and to each other.
[0045] It should be noted that the embodiments of the present application do not limit the specific structure of the reinforcement because the specific structure of the reinforcement includes multiple embodiments. For example, the reinforcement includes structures such as reinforcement plates, reinforcement ribs or reinforcement rods. These structures all fall within the protection scope of the embodiments of the present application. The preferred embodiments of the reinforcement will be described below.
[0046] The specific implementation of the small offset collision structure 30 of the vehicle body 100 is described below through the preferred embodiment of the present application.
[0047] like Figures 1 to 6 As shown, in some embodiments, the two reinforcement members include a first reinforcement plate 31 disposed on the front wheel housing 10 and a second reinforcement plate 32 disposed on the rocker 20 , and the first reinforcement plate 31 and the second reinforcement plate 32 are distributed along the small offset collision path L.
[0048] In this embodiment, the first reinforcing plate 31 is arranged according to the structural contour of the front wheel cover 10, and the second reinforcing plate 32 is arranged according to the structural contour of the door sill 20, thereby improving the fit between the two reinforcing plates and the front wheel cover 10 and the door sill 20 and the force transmission efficiency, so that small offset collision energy can be evenly transmitted between the front wheel cover 10 and the door sill 20.
[0049] Specifically, the small offset collision path L described in the embodiment of the present application is distributed at the edge of the vehicle body 100, located at the wheel arch and the door sill 20, and is related to the collision percentage of the vehicle body 100 involved in the small offset collision. For example, the collision percentage of the vehicle body 100 includes 25% and 40%. When the collision percentage of the vehicle body 100 is 25%, the width of the first reinforcing plate 31 and the second reinforcing plate 32 covers 25% of the width of the edge of the vehicle body 100; when the collision percentage of the vehicle body 100 is 40%, the width of the first reinforcing plate 31 and the second reinforcing plate 32 covers 40% of the width of the edge of the vehicle body 100.
[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the first reinforcing plate 31 is distributed at the bottom of the front wheel cover 10 along the height direction of the front wheel cover 10, and the second reinforcing plate 32 is distributed at the bottom of the door sill 20 along the longitudinal direction of the door sill 20, and the first reinforcing plate 31 and the second reinforcing plate 32 are spliced into an L-shaped supporting structure.
[0051] In the present embodiment, the front wheel cover 10 is configured as an arch structure distributed along the height direction of the vehicle body 100, and the docking position between the front wheel cover 10 and the door sill 20 is a roughly vertical structure. The small offset collision energy is transmitted from top to bottom at this position to the bottom of the front wheel cover 10. In order to enable the first reinforcing plate 31 to absorb the small offset collision energy to the greatest extent, the embodiment of the present application proposes to distribute the first reinforcing plate 31 along the height direction of the front wheel cover 10 at the bottom of the front wheel cover 10, so that the first reinforcing plate 31 can absorb the small offset collision energy along the transmission path of the small offset collision energy.
[0052] Similarly, the door sill 20 is configured as a longitudinal structure distributed along the length direction of the vehicle body 100, and the docking position between the door sill 20 and the front wheel cover 10 is a longitudinal structure along the length direction of the vehicle body 100. The small offset collision energy is distributed along the front and rear direction of the vehicle body 100. In order to enable the second reinforcement plate 32 to absorb the small offset collision energy to the greatest extent, the embodiment of the present application proposes to distribute the second reinforcement plate 32 at the bottom of the door sill 20 along the longitudinal direction of the door sill 20, so that the second reinforcement plate 32 can absorb the small offset collision energy along the transmission direction of the small offset collision energy.
[0053] Meanwhile, the second reinforcing plate 32 is disposed at the bottom of the threshold 20 , which does not affect the normal use of the top of the threshold 20 . For example, the second reinforcing plate 32 will not trip the user's feet or affect the appearance of the threshold 20 .
[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the first reinforcing plate 31 is provided with an L-shaped slot 311 corresponding to the second reinforcing plate 32 , and the second reinforcing plate 32 is plugged into the L-shaped slot 311 and welded to the first reinforcing plate 31 .
[0055] In this embodiment, the first reinforcing plate 31 can position and snap-fit the second reinforcing plate 32 through the L-shaped slot 311, and the initial positioning between the first reinforcing plate 31 and the second reinforcing plate 32 is achieved through the L-shaped slot 311, and then the first reinforcing plate 31 and the second reinforcing plate 32 are fixed, thereby reducing the shaking of the first reinforcing plate 31 and the second reinforcing plate 32 during the fixing process.
[0056] Furthermore, the L-shaped slot 311 can be used to achieve docking of at least two sides of the first reinforcing plate 31 and the second reinforcing plate 32, thereby increasing the contact area between the first reinforcing plate 31 and the second reinforcing plate 32, improving the connection reliability between the first reinforcing plate 31 and the second reinforcing plate 32, and reducing the stress concentration phenomenon during the connection or force transmission process between the first reinforcing plate 31 and the second reinforcing plate 32.
[0057] like Figure 2 and Figure 3 As shown, in some embodiments, along the width direction of the vehicle body 100, the first reinforcing plate 31 has an edge portion 312 that exceeds the outer edge of the second reinforcing plate 32, and the first reinforcing plate 31 is provided with a notch on the inner side of the edge portion 312, and the edge portion 312 and the notch form an L-shaped slot 311.
[0058] In this embodiment, it can be understood by those skilled in the art that the width of the front wheel cover 10 is greater than the width of the door sill 20, and the outer edge of the front wheel cover 10 will protrude from the outer edge of the door sill 20, that is, a portion of the outer edge of the front wheel cover 10 is not connected to the door sill 20, and the first reinforcing plate 31 proposed in the embodiment of the present application covers this portion. On the one hand, the overall structural strength of the front wheel cover 10 can be improved, and on the other hand, the portion of the outer edge of the front wheel cover 10 protruding from the door sill 20 can form an L-shaped slot 311 with the inner notch, and the second reinforcing plate 32 is clamped through the L-shaped slot 311, thereby improving the connection reliability between the first reinforcing plate 31 and the second reinforcing plate 32.
[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the first reinforcing plate 31 and / or the second reinforcing plate 32 are configured as honeycomb plates, and the honeycomb plates are configured as an integrally formed structure.
[0060] In this embodiment, by configuring the first reinforcing plate 31 and / or the second reinforcing plate 32 as a honeycomb plate, the weight and cost of the first reinforcing plate 31 and / or the second reinforcing plate 32 can be further reduced, thereby improving the small offset collision performance of the vehicle body 100 without increasing the weight and cost of the vehicle body 100 too much.
[0061] like Figures 1 to 6As shown, in some embodiments, a plurality of honeycomb holes are formed inside the honeycomb panel, and the plurality of honeycomb holes are separated by a plurality of partitions, and the density of the plurality of honeycomb holes and / or the plurality of partitions is distributed according to the small offset collision path L.
[0062] In this embodiment, in order to improve the small offset collision performance of the vehicle body 100 without increasing the weight and cost of the vehicle body 100 too much, the embodiment of the present application proposes to distribute multiple honeycomb holes and / or multiple partitions along the small offset collision path L.
[0063] Specifically, at the junction of the front wheel cover 10 and the door sill 20, the small offset collision energy is vertically distributed along the height direction of the vehicle body 100, and the first reinforcement plate 31 is also vertically distributed along the height direction of the vehicle body 100. At this time, multiple honeycomb holes and / or multiple partitions are vertically distributed along the height direction of the vehicle body 100, and the density of the partition of the first reinforcement plate 31 facing the small offset collision path is relatively large, thereby improving the small offset collision performance of the first reinforcement plate 31 without increasing the weight and cost of the vehicle body 100 too much.
[0064] Similarly, at the junction of the door sill 20 and the front wheel cover 10, the small offset collision energy is longitudinally distributed along the length direction of the vehicle body 100, and the second reinforcement plate 32 is also longitudinally distributed along the length direction of the vehicle body 100. At this time, multiple honeycomb holes and / or multiple partitions are longitudinally distributed along the length direction of the vehicle body 100, and the density of the partition of the second reinforcement plate 32 facing the small offset collision path is relatively large, thereby improving the small offset collision performance of the second reinforcement plate 32 without increasing the weight and cost of the vehicle body 100 too much.
[0065] like Figures 1 to 8 As shown, in some embodiments, the plurality of honeycomb holes include edge honeycomb holes 321 located at the outer edge of the honeycomb panel, and middle honeycomb holes 322 located in the middle of the honeycomb panel, and the size of the edge honeycomb holes 321 is smaller than that of the middle honeycomb holes 322 .
[0066] In this embodiment, if Figure 7 and Figure 8As shown, during a small offset collision of the vehicle body 100, the side of the vehicle body 100 where the small offset collision occurs will tilt toward the other side of the vehicle body 100 (that is, the rear end of the vehicle body 100 will shift toward the side away from the collision object 200), causing the two reinforcing plates to tilt toward the other side of the vehicle body 100. When the two reinforcing plates tilt toward the other side of the vehicle body 100, the edges of the reinforcing plates will tilt to a position facing the small offset collision path L. At this time, the edges of the reinforcing plates will become the main load-bearing points of the small offset collision. Therefore, the embodiment of the present application proposes that the size of the edge honeycomb holes 321 is smaller, so that the peripheral partitions of the edge honeycomb holes 321 can withstand a larger small offset collision force, thereby improving the load-bearing capacity of the reinforcing plates and reducing the amount of intrusion of small offset collisions into the vehicle.
[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the reinforcement is provided with a mounting hole 301 penetrating the reinforcement along the thickness direction of the reinforcement, and the small offset collision structure 30 further includes a fastener, which penetrates the mounting hole 301 to detachably mount the reinforcement to the vehicle body 100 .
[0068] In this embodiment, the fasteners include bolts and rivets, and the reinforcement is fastened to the vehicle body 100 by the fasteners, which can not only improve the connection stability between the reinforcement and the vehicle body 100, but also reduce the stress concentration phenomenon between the reinforcement and the vehicle body 100.
[0069] Furthermore, when a reinforcement is damaged due to a small offset collision, the damaged reinforcement can be removed from the vehicle body 100 and then replaced with a new reinforcement, thereby improving the working reliability of the small offset collision structure 30.
[0070] like Figures 1 to 6 As shown, the second aspect of the present application provides a vehicle, the vehicle comprising a vehicle body 100 and the small offset collision structure 30 of the vehicle body 100 of the first aspect of the present application.
[0071] In this embodiment, the vehicle described in the embodiment of the present application has all the technical effects of the small offset collision structure 30 of the vehicle body 100 of the first aspect of the present application, which will not be described in detail here.
[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
[0073] In addition, the embodiments of the present application only illustrate the preferred distribution position of the small offset collision structure 30 of the vehicle body 100, and do not limit the distribution position of the small offset collision structure 30. For example, the small offset collision structure 30 of the vehicle body 100 can also be arranged between the rear wheel cover and the rear bumper. These embodiments all belong to the protection scope of the small offset collision structure 30 of the vehicle body 100 of the embodiments of the present application, and other embodiments of the small offset collision structure 30 of the vehicle body 100 will not be described one by one here.
[0074] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
