[0038] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.
[0039] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0040] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.
[0041] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, said acceptable deviation range being determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.
[0042] This application provides a vehicle 100, which can be a pure gasoline vehicle, a pure electric vehicle, a hybrid electric vehicle, etc. The vehicle 100 can also be a sedan, bus, truck, pickup truck, trailer, etc. The embodiments of this application do not specifically limit the type of vehicle 100.
[0043] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a body 10, which can be used to install components required for the vehicle 100, such as wheels 20 and doors 30. The wheels 20 are connected to the underside of the body 10 and are used to propel the vehicle 100 by their own rolling motion. The doors 30 are located on both sides of the body 10 in the width direction and form passageways for passengers to get on and off the vehicle.
[0044] In some embodiments, the vehicle body 10 further includes side panels 1, with one side panel 1 on each side of the vehicle body 10 in the width direction. Door openings can be provided in the side panels 1, and doors 30 can be installed at the door openings to form a passage for passengers to get on and off the vehicle.
[0045] In some implementations, see Figure 2 The side panel 1 of the vehicle 100 includes a reinforcing plate 11. The reinforcing plate 11 has a first door opening 111 and a second door opening 112. The portion of the reinforcing plate 11 with the first door opening 111 and the portion with the second door opening 112 are integrally formed.
[0046] In the above scheme, one of the first doorway 111 and the second doorway 112 is the front doorway of the vehicle 100, and the other is the rear doorway of the vehicle 100. The portion of the reinforcing plate 11 with the front doorway and the portion with the rear doorway are integrally formed. At this time, the reinforcing plate 11 is a one-piece structure, eliminating the overlapping part 126a required by the welding process in the prior art. This reduces the weight of the reinforcing plate 11, thereby reducing the weight of the side panel 1 and improving the lightweight of the vehicle body 10.
[0047] In some examples, the reinforcing plate 11 can be integrally formed using a stamping process. When the reinforcing plate 11 is integrally formed, on the one hand, the overlapping structure of the welding process can be eliminated, improving the lightweight of the vehicle body 10; on the other hand, since the reinforcing plate 11 is processed from a single sheet of material, the overall integrity of the reinforcing plate 11 is better, which can improve the support strength of the reinforcing plates 11 on both sides of the vehicle 100 for the roof, thereby improving the static pressure and collision performance of the roof.
[0048] It should be noted that the first door opening 111 and the second door opening 112 are arranged along the length of the vehicle body 10. The first door opening 111 can be a front door opening, and the second door opening 112 can be a rear door opening of the vehicle 100. Both the first door opening 111 and the second door opening 112 are used to install the door 30.
[0049] In some implementations, see Figure 2 The side panel 1 also includes an inner panel 12, which is located inside the reinforcing plate 11 and is stacked with the reinforcing plate 11. The inner panel 12 has a third doorway 121 and a fourth doorway 122. The third doorway 121 is opposite to the first doorway 111, and the fourth doorway 122 is opposite to the second doorway 112. The portion of the inner panel 12 with the third doorway 121 and the portion with the fourth doorway 122 are integrally formed.
[0050] In the above scheme, the inner panel 12 and the reinforcing plate 11 are stacked, which can improve the strength of the side panel 1. When the portion of the inner panel 12 with the third door opening 121 and the portion with the fourth door opening 122 are integrally formed, the inner panel 12 in the side panel 1 is also an integrally formed structure. This eliminates the original overlapping structure of the inner panel 12 and further improves the lightweight of the side panel 1 of the vehicle 100.
[0051] In some examples, the inner plate 12 is welded to the reinforcing plate 11.
[0052] In other examples, the inner plate 12 and the reinforcing plate 11 are connected by fasteners such as bolts.
[0053] In some examples, the inner panel 12 is integrally formed using a stamping process.
[0054] In some examples, the third doorway 121 and the first doorway 111 together form the front doorway of the vehicle 100, and the fourth doorway 122 and the second doorway 112 together form the rear doorway of the vehicle 100.
[0055] In some other embodiments, the portion of the inner panel 12 with the third door opening 121 and the portion with the fourth door opening 122 are welded together.
[0056] In some implementations, see Figure 2 The side panel 1 also includes an outer panel 13, which is located on the side of the reinforcing plate 11 facing away from the inner panel 12. The outer panel 13 has a fifth doorway 131 and a sixth doorway 132. The fifth doorway 131 is opposite to the first doorway 111, and the sixth doorway 132 is opposite to the second doorway 112. The portion of the outer panel 13 with the fifth doorway 131 and the portion with the sixth doorway 132 are integrally formed.
[0057] In the above scheme, the portion of the outer panel 13 with the fifth door opening 131 and the portion with the sixth door opening 132 are integrally formed, thus the outer panel 13 is an integrally formed structure. The outer panel 13 is provided on the side of the reinforcing plate 11 facing away from the inner panel 12, and the outer panel 13 adopts an integrally formed structure. This improves the overall strength of the side panel 1 on the one hand; on the other hand, since the outer panel 13 has no overlapping structure, it improves the aesthetic appearance of the side panel 1 of the vehicle 100.
[0058] Since the outer panel 13, reinforcing plate 11 and inner panel 12 forming the side panel 1 are all integrally molded structures, the processing steps of the side panel 1 and the corresponding inspection tools are reduced, thereby improving the lightweight and strength of the body 10 while reducing the production cost of the side panel 1.
[0059] In some examples, the outer panel 13 is integrally formed using a stamping process.
[0060] In some examples, the outer plate 13 and the reinforcing plate 11 are connected by welding.
[0061] In other examples, the outer plate 13 is connected to the reinforcing plate 11 by fasteners such as bolts.
[0062] In some examples, the first doorway 111, the third doorway 121 and the fifth doorway 131 together form the front doorway of the vehicle body 10, and the second doorway 112, the fourth doorway 122 and the sixth doorway 132 together form the rear doorway of the vehicle body 10.
[0063] In some embodiments, the first doorway 111 and the second doorway 112 are connected to form a first through doorway, the third doorway 121 and the fourth doorway 122 are connected to form a second through doorway, and the fifth doorway 131 and the sixth doorway 132 are connected to form a third through doorway. The first through doorway, the second through doorway, and the third through doorway are opposite each other.
[0064] In the above scheme, when the first doorway 111 and the second doorway 112 are connected, the third doorway 121 and the fourth doorway 122 are connected, and the fifth doorway 131 and the sixth doorway 132 are connected, then the front doorway and the rear doorway of the vehicle 100 are connected. At this time, one door 30 or two doors 30 can be set on one side of the vehicle 100 in the width direction, which improves the flexibility of the door 30 setting in the vehicle 100.
[0065] In some examples, a door 30 may be provided on one side of the vehicle in the width direction of the vehicle 100.
[0066] In other examples, two doors 30 may be provided on one side of the vehicle 100 in the width direction, wherein one door 30 is located in the first doorway 111 and the other door 30 is located in the second doorway 112, and the two doors 30 may be arranged in a double-opening manner.
[0067] In some implementations, see Figure 2 The portion of reinforcing plate 11 located on the side of the first doorway 111 facing away from the second doorway 112 is the first reinforcing portion 113, and the portion of reinforcing plate 11 located on the side of the second doorway 112 facing away from the first doorway 111 is the second reinforcing portion 114. The portion of inner plate 12 located on the side of the third doorway 121 facing away from the fourth doorway 122 is the first inner plate portion 123, and the portion of inner plate 12 located on the side of the fourth doorway 122 facing away from the third doorway 121 is the second inner plate portion 124. The portion of outer plate 13 located on the side of the fifth doorway 131 facing away from the sixth doorway 132 is the first outer plate portion 133, and the portion of outer plate 13 located on the side of the sixth doorway 132 facing away from the fifth doorway 131 is the second outer plate portion 134.
[0068] The first reinforcing portion 113, the first inner panel portion 123 and the first outer panel portion 133 form the A-pillar 14 of the vehicle 100, and the second reinforcing portion 114, the second inner panel portion 124 and the second outer panel portion 134 form the C-pillar 16 of the vehicle 100.
[0069] In the above scheme, since the second reinforcing part 114, the second inner panel part 124, and the second outer panel part 134 form the C-pillar 16 of the vehicle 100, and the portion of the reinforcing plate 11 located on the side of the second door opening 112 opposite to the first door opening 111 is the second reinforcing part 114, the portion of the inner panel 12 located on the side of the fourth door opening 122 opposite to the third door opening 121 is the second inner panel part 124, and the portion of the outer panel 13 located on the side of the sixth door opening 132 opposite to the fifth door opening 131 is the second outer panel part 134, it means that along the length direction of the vehicle body 10, the length of the reinforcing plate 11, the inner panel 12, and the outer panel 13 only extends to the C-pillar 16 of the vehicle 100, that is, it does not include the D-pillar or trunk of the vehicle 100, which can reduce the length of the side panel 1 and reduce its production cost.
[0070] In some examples, since the side panel 1 does not include the D-pillar or trunk, and the pickup truck 100 has no trunk and D-pillar, the side panel 1 can be applied to the pickup truck 100 to improve the lightweight and structural strength of the pickup truck 100 body 10.
[0071] In other examples, the side panel 1 can also be applied to a sedan or SUV vehicle 100, wherein structures such as the D-pillar or the trunk can be welded to the side panel 1.
[0072] In some implementations, see Figure 2 The portion of the reinforcing plate 11 located between the first doorway 111 and the second doorway 112 is the third reinforcing portion 115; the portion of the inner plate 12 located between the third doorway 121 and the fourth doorway 122 is the third inner plate portion 125; and the portion of the outer plate 13 located between the fifth doorway 131 and the sixth doorway 132 is the third outer plate portion 135. The third reinforcing portion 115, the third inner plate portion 125, and the third outer plate portion 135 together form the B-pillar 15 of the vehicle 100.
[0073] In the above scheme, a third reinforcing portion 115 is provided between the first doorway 111 and the second doorway 112, that is, the third reinforcing portion 115 is supported between the first doorway 111 and the second doorway 112 along the height direction of the vehicle 100, thereby improving the structural strength of the reinforcing plate 11. A third inner plate portion 125 is provided between the third doorway 121 and the fourth doorway 122, that is, the third inner plate portion 125 is supported between the third doorway 121 and the fourth doorway 122 along the height direction of the vehicle 100, thereby improving the structural strength of the inner plate 12. A third outer plate portion 135 is provided between the fifth doorway 131 and the sixth doorway 132, that is, the third outer plate portion 135 is supported between the fifth doorway 131 and the sixth doorway 132 along the height direction of the vehicle 100, thereby improving the structural strength of the outer plate 13.
[0074] When the third reinforcing part 115, the third inner panel part 125 and the third outer panel part 135 are connected to form the B-pillar 15 of the vehicle 100, the overall strength of the side panel 1 can be improved, thereby improving the safety performance of the vehicle 100.
[0075] In some examples, the B-pillar 15 of the vehicle 100 and the side panel 1 are integrally formed. For example, the third reinforcing part 115 is integrally formed with the reinforcing plate 11, the third inner panel part 125 is integrally formed with the inner panel 12, and the third outer panel part 135 is integrally formed with the outer panel 13.
[0076] In other examples, the B-pillar 15 of the vehicle 100 and the side panel 1 are spliced together. For example, the third reinforcing part 115 is welded to the reinforcing plate 11, the third inner panel part 125 is welded to the inner panel 12, and the third outer panel part 135 is welded to the outer panel 13.
[0077] In some other examples, a portion of the B-pillar 15 of the vehicle 100 is integrally formed with the side panel 1, while another portion is spliced and connected to the side panel 1. For example, the third reinforcing portion 115 is integrally formed with the reinforcing plate 11, the third inner panel 12 is welded to the inner panel 12, and the third outer panel 13 is welded to the outer panel 13.
[0078] In some implementations, see Figure 2 and Figure 3 The portion of the inner panel 12 located below the third doorway 121 and the fourth doorway 122 arches away from the reinforcing plate 11 to form a threshold 126, which is adapted to be directly connected to the floor 2 of the vehicle 100 or indirectly connected via a transition piece 3.
[0079] In the above scheme, the sill 126 is formed by the part located on the lower side of the inner plate 12 arching away from the reinforcing plate 11, and the floor 2 of the vehicle 100 is connected to the sill 126. The structure is simple and easy to process.
[0080] In some examples, the floor 2 of vehicle 100 is welded to the sill 126.
[0081] In other examples, the floor 2 of vehicle 100 is connected to the sill 126 by fasteners such as bolts.
[0082] It should be noted that in the above scheme, since the lower part of the inner panel 12 arches away from the reinforcing plate 11 to form a sill 126, and the arched lower part of the inner panel 12 forms a groove, when the floor 2 is connected to the sill 126, the welding tool needs to be inserted into the groove, that is, there should be no obstruction on the side of the groove facing away from the arch. At this time, the side panel 1 and the floor 2 of the vehicle 100 are suitable for a double-assembly connection process, which can be adapted to the existing double-assembly production line, that is, the floor 2 is first connected to the sill 126, and then the inner panel 12 is connected to the reinforcing plate 11.
[0083] In some implementations, see Figure 5 , Figure 6 and Figure 7 The sill 126 includes an overlap portion 126a, which is suitable for direct connection to the floor 2 via the overlap portion 126a or indirect connection to the floor 2 via a transition member 3. Connecting the floor 2 of the vehicle 100 to the overlap portion 126a of the sill 126 results in a simple structure that is easy to manufacture.
[0084] In some examples, see Figure 5 The upper surface of the sill 126 is an overlap 126a. The floor 2 of the vehicle 100 can be directly overlapped with the upper surface of the sill 126 and welded together. At this time, the floor 2 is located on the upper side of the sill 126.
[0085] In other examples, see Figure 6 The side of the sill 126 facing away from the reinforcing plate 11 is an overlapping part 126a. The floor 2 of the vehicle 100 can be overlapped with the side of the sill 126 and welded together. At this time, the floor 2 is located on the side of the sill 126.
[0086] In some examples, see Figure 7 The overlapping portion 126a of the threshold 126 is connected to the floor 2 via a transition piece 3. One side of the transition piece 3 is connected to the threshold 126, and the other side is connected to the floor 2. The transition piece 3 can be connected to the threshold 126 and the floor 2 by welding or by bolts.
[0087] In some examples, see Figure 8 The portion of the inner panel 12 located below the third doorway 121 and the fourth doorway 122 includes an extension 126b extending away from the reinforcing plate 11. The side panel 1 also includes a support plate 126c located below the inner panel 12 and connected to the reinforcing plate 11 and the extension 126b. The extension 126b and the support plate 126c form a sill 126, and the support plate 126c is used to connect to the floor 2 of the vehicle 100.
[0088] In the above solution, since the floor 2 is connected to the support plate 126c, and the upper side of the support plate 126c is the extension 126b of the inner panel 12, and there is no obstruction on the upper side of the extension 126b, the inner panel 12 and the reinforcing plate 11 can be connected simultaneously with the floor 2 and the support plate 126c. This adapts to existing single assembly production lines and improves the flexibility of connecting the side panel 1 and the floor 2.
[0089] In some examples, a portion of the floor 2 may be located between the extension 126b and the support plate 126c, and the extension 126b, the floor 2, and the support plate 126c may be welded together.
[0090] In other examples, a portion of the floor 2 is located on the side of the support plate 126c opposite to the extension 126b.
[0091] In some other examples, the floor 2 may be located on the side of the extension 126b opposite to the support plate 126c.
[0092] In some implementations, see Figure 4 The third doorway 121 and the fourth doorway 122 penetrate the lower edge of the inner panel 12. The side panel 1 also includes a threshold 126, which is located on the lower side of the inner panel 12. The threshold 126 blocks the lower openings of the third doorway 121 and the fourth doorway 122 and is fixedly connected to the inner panel 12. Along the thickness direction of the side panel 1, the threshold 126 is opposite to the reinforcing plate 11.
[0093] In the above solution, the sill 126 is located on the lower side of the inner panel 12 and blocks the third doorway 121 and the fourth doorway 122. Therefore, the sill 126 and the inner panel 12 are separate components. The sill 126 can be connected to the inner panel 12 first, or it can be connected to the floor 2 first. When the sill 126 is connected to the floor 2 first, the problem of obstruction during welding of the sill 126 to the floor 2 can be avoided. This improves the lightweighting of the vehicle body 10 while also enhancing the ease of connection between the sill 126 and the floor 2.
[0094] In some examples, the threshold 126 and the inner plate 12 can be connected by welding.
[0095] In other examples, the threshold 126 and the inner plate 12 can be connected by bolts.
[0096] In some examples, during the assembly of the body 10, the sill 126 can be connected to the floor 2 first, and then the sill 126 can be connected to the inner panel 12, which is applicable to single assembly production lines.
[0097] In some other examples, the threshold 126 may be connected to the inner panel 12 first, and then the floor 2 may be connected to the threshold 126.
[0098] In some examples, the threshold 126 is welded to the reinforcing plate 11.
[0099] In some implementations, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The portion of the reinforcing plate 11 opposite to the sill 126 arches away from the sill 126. In this way, a cavity is formed between the reinforcing plate 11 and the sill 126, and the portion of the reinforcing plate 11 opposite to the sill 126 is fitted to the sill 126, which can improve the structural strength of the sill 126 and enhance the safety performance of the vehicle 100.
[0100] In some examples, the cross-section of the cavity between the reinforcing plate 11 and the threshold 126 can be directional, circular, etc.
[0101] In some other embodiments, the portion of the reinforcing plate 11 opposite to the threshold 126 is fitted to the threshold 126.
[0102] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0103] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
