Description

[Technical field]

[0001] An aspect of the invention relates to a vehicle side structure including a longitudinally extending side portion, the side portion comprising a longitudinally extending first member and a longitudinally extending second member, the first member configured to face an interior side of the vehicle and the second member configured to face an exterior side of the vehicle, the first member and the second member attached to one another to form a substantially enclosed space. [Background technology]

[0002] In the design of a frame section for a self-propelled vehicle, there is a compromise between weight and strength. An advantageous approach to obtain a good compromise is to produce the frame section from one or more metal sheets formed into the required shape, for example into a hat shape.

[0003] In general, frame parts of a self-propelled vehicle are formed to have a certain rigidity since they may be subjected to various shocks from the outside. At the same time, some frame parts should be able to deform to absorb shocks when overloaded, for example, by a collision with an external object, for example, another vehicle, or a stationary object, for example, a tree. One example of a vehicle frame part that should be able to deform to absorb shocks while remaining rigid is the side sill structure of the vehicle. Summary of the Invention [Means for solving the problem]

[0004] The present inventors have realized that further improvements can be made to the vehicle side structure.

[0005] It is therefore an object of an embodiment of the present invention to provide an improved vehicle side structure.

The first member is configured to face an interior side of the vehicle. The second member is configured to face an exterior side of the vehicle. The first member and the second member are attached to each other to define a substantially closed space therebetween.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0054] 1, 2 and 6, the side portion 104 of the vehicle side structure 102 with the first embedment includes a first reinforcing member 118 and a second reinforcing member 120. Each reinforcing member 118, 120 extends in the same longitudinal direction 106. Each of the first and second reinforcing members 118, 120 is formed from a metal plate, such as a plate of aluminum or any other suitable material, which can be processed by press hardening. Each reinforcing member 118, 120 is smoothly corrugated in the longitudinal direction 106.

[0055] Each reinforcing member 118, 120 has a first leg 122, 124 extending transversely to the longitudinal direction 106. Each reinforcing member 118, 120 has a second leg 126, 128 extending transversely to the longitudinal direction 106. Each leg 122, 124, 126, 128 has a foot 130, 132, 134, 136 extending in the longitudinal direction 106. Each foot 130, 132, 134, 136 can be configured in a variety of ways. With reference to the first embodiment of Figures 1 to 6, each foot 130, 132, 134, 136 can be a curved portion at the end of the respective leg 122, 124, 126, 128. However, the foot can also be a straight portion at the end of the respective leg 122, 124, 126, 128.

[0056] 6, the foot 130 of the first leg 122 and the foot 134 of the second leg 126 of the first reinforcing member 118 are spaced apart from one another to form an interior space 158 between the first leg 122 and the second leg 126 of the first reinforcing member 118. The foot 132 of the first leg 124 and the foot 136 of the second leg 128 of the second reinforcing member 120 are spaced apart from one another to form an interior space 159 between the first leg 124 and the second leg 128 of the second reinforcing member 120.

[0057] The first leg 122 and the second leg 126 of the first reinforcing member 118 are joined at a first head section 138. The first head section 138 may also be referred to as a first head portion. The first leg 124 and the second leg 128 of the second reinforcing member 120 are joined at a second head section 140. The second head section 140 may also be referred to as a second head portion. "Joined" with respect to each head section 138, 140 and the first and second legs 122, 124, 126, 128 means that the two legs 122, 124, 126, 128, i.e., the first leg 122, 124 and the second leg 128, 128, are connected or attached to each other at the first or second head section 138, 140. The head section 138, 140 and legs 122, 124, 126, 128 of each reinforcing member 118, 120 can be described as forming a U-shape with the foot 130, 132, 134, 136 terminating in the U. Thus, each reinforcing member 118, 120 has a U-shaped cross-section, although other shapes are possible, such as a V-shaped cross-section.

[0058] Each leg 122, 124, 126, 128 is corrugated in the longitudinal direction 106 to form a smooth wave shape. Each leg 122, 124, 126, 128 may be corrugated along substantially its entire longitudinal extent or length. The corrugations of the first and second legs 122, 124, 126, 128 of each reinforcing member 118, 120 include ridges 142, 144, 146, 148 and grooves 150, 152, 154, 156. Each leg 122, 124, 126, 128 may include a plurality of ridges 142, 144, 146, 148, e.g., five ridges 142, 144, 146, 148 or more, and a plurality of grooves 150, 152, 154, 156, e.g., five grooves 150, 152, 154, 156 or more. The ridges 142, 144 and grooves 150, 152 of the first reinforcing member 118 extend from the first head section 138 of the first reinforcing member 118 to the respective feet 130, 134. The ridges 146, 148 and grooves 154, 156 of the second reinforcing member 120 extend from the second head section 140 of the second reinforcing member 120 to the respective feet 132, 136. Thus, each leg 122, 124, 126, 128 has a smooth corrugation. These innovative corrugations provide advantageous deformation of the vehicle side structure 102 to absorb impacts while maintaining or improving the stiffness and reinforcement of the vehicle side structure 102.

[0059] The first reinforcing member 118 is attached to the second reinforcing member 120. Thus, the first reinforcing member 118 and the second reinforcing member 120 are attached to one another. A foot 130 of the first leg 122 of the first reinforcing member 118 may be attached to a foot 132 of the first leg 124 of the second reinforcing member 120, such as by a mechanical locking structure, such as welding, adhesive, or rivets, or any other suitable fastening means. A foot 134 of the second leg 126 of the first reinforcing member 118 may be attached to a foot 136 of the second leg 128 of the second reinforcing member 120, such as by a mechanical locking structure, such as welding, adhesive, or rivets, or any other suitable fastening means. The feet 130, 134 may be attached to opposing feet 132, 136 in the longitudinal direction 106 along their entire longitudinal length or extent.

[0060] With reference to FIG. 6, the first reinforcing member 118 defines an interior space 158 between the first leg 122 and the second leg 126 of the first reinforcing member 118. The second reinforcing member 120 is at least partially located within the interior space 158 defined by the first reinforcing member 118. The second head section 140 is located within the interior space 158 defined by the first reinforcing member 118. However, the feet 132, 136 of the second reinforcing member 120 are located outside of the interior space 158 defined by the first reinforcing member 118. With reference to FIGS. 1, 2 and 6, the first reinforcing member 118 has a plurality of attachment tabs 157a-157g configured for attachment to the first and / or second members 108, 110, as disclosed in more detail below. A plurality of mounting tabs 157a-157g may be provided on the feet 130, 134 of the first stiffening member 118. In an alternative embodiment, the second stiffening member 120 may include the mounting tabs 157a-157g. The mounting tabs 157a-157g may be integral with the first stiffening member 118 (i.e., formed as a unit with the first stiffening member 118) and may be attached to the first stiffening member 118, such as by welding, adhesive, or mechanical locking structures such as rivets, or any other suitable fastening means.

[0061] 3 to 6, the vehicle side structure 102 includes a side portion 104 extending in a longitudinal direction 106. The side portion 104 has a first member 108 extending in the longitudinal direction 106. The side portion 104 has a second member 110 extending in the longitudinal direction 106. The first member 108 is configured to face an inner side 112 of a vehicle, e.g., a motor vehicle such as a passenger car. The second member 110 is configured to face an outer side 114 of the same vehicle. The first member 108 and the second member 110 are attached to each other to form a substantially closed space 116 therebetween. The first member 108 and the second member 110 may be attached to each other, e.g., by welding, adhesive, or a mechanical locking structure such as a rivet, or any other suitable fastening means. Each of the first and second members 108, 110 may be formed from a metal plate, for example an aluminum plate, that may be processed by press hardening. In the first embodiment shown, each of the first and second members 108, 110 is hat-shaped, but may also be U-shaped. It should be understood that one or more additional sections or one or more additional members may be placed between the first or second members 108, 110 and the inside 112 or outside 114 of the vehicle, especially when the vehicle is already assembled.

[0062] A first head section 138 of the first reinforcing member 118 faces one 108, 110 of the first and second members 108, 110, and a foot 130, 134 of the first reinforcing member 118 faces the other 108, 110 of the first and second members 108, 110. With reference to Figure 6, in the first embodiment shown, the first head section 138 of the first reinforcing member 118 faces the first member 108, and the foot 130, 134 of the first reinforcing member 118 faces the second member 110, although the reverse orientation is also possible.

Instead, there may be other members or units between them. The fact that the second head section 140 faces one 108, 110 of the first and second members 108, 110 and the foot 132, 136 of the second reinforcing member 120 faces the other 108, 110 of the first and second members 108, 110 does not necessarily mean that there is an open space between the second head section 138 or the foot 132, 136 and the first member 108 or the second member 110. Instead, there may be other members or units between them.

[0063] 6, the first and second reinforcing members 118, 120 are attached to at least one of the first and second members 108, 110, where the second reinforcing member 120 is indirectly attached to one of the first and second members 108, 110 via the first reinforcing member 118.

[0066] Advantageously, assembly of the side portion 104 may proceed by first attaching the first reinforcing member 118 and the second reinforcing member 120 to one another, followed by attaching them to one of the first and second members 108, 110, and then attaching the first member 108 and the second member 110 to one another. In an alternative embodiment, the first head section 138 may be attached to one of the first and second members 108, 110, for example to the first member 108.

[0067] 7, 8 and 12, the side portion 204 of the vehicle side structure 202 with the second embedment has a first reinforcing member 218 and a second reinforcing member 220. Each reinforcing member 218, 220 extends in the same longitudinal direction 206. Each reinforcing member 218, 220 is formed from a metal plate, such as a plate of aluminum or any other suitable material, which can be processed by press hardening. Each reinforcing member 218, 220 is smoothly corrugated in the longitudinal direction 206.

[0068] Each reinforcing member 218, 220 has a first leg 222, 224 extending transversely to the longitudinal direction 206.

Additionally, in alternative embodiments, each ridge 242, 244 of the first reinforcing member 218 may gradually increase in size from the foot 230, 234 toward the first head section 238 of the first reinforcing member 218. Corrugations having more protruding and less protruding ridges may optionally be applied to the first and / or second reinforcing members 118, 120 of the first embodiment of Figures 1-6.

[0088] In both the first and second embodiments disclosed above, the first reinforcing member 118;218 and the second reinforcing member 120;220 may be different in size, whereby the deformation behavior of the vehicle side structure for absorbing impact as well as the stiffness and reinforcement of the vehicle side structure can be further adjusted and adapted to a specific application. Advantageously, the head section 140;240 of the smaller reinforcing member 120;220 faces the first member 108;208.

[0089] The vehicle side structure 102, 202 can be used, for example, in an electric or hybrid vehicle, but of course also in a standard vehicle having only a combustion engine. The vehicle side structure 102, 202 can be configured to protect one or more batteries of the electric or hybrid vehicle. The vehicle side structure 102, 202 can be located on one or more sides of the battery.

[0090] Each of the described side portions 104;204 is advantageously used as a side sill portion 104;204. Thus, each of the described side portions 104;204 may be a side sill portion 104;204. The side sill portion 104;204 extends in the longitudinal direction 106;206 of the vehicle body and is provided on the side of the vehicle body. Advantageously, the side sill portion 104;204 is attached to one or more cross beams 184,186;284,286 of the vehicle body, for example two cross beams 184,186;284,286.

[0091] The features of the different embodiments of the vehicle side structure disclosed above can be combined in various possible ways to provide further advantageous embodiments. The present invention is not to be construed as being limited to the illustrated embodiments, but can be modified and altered in many ways by those skilled in the art without departing from the scope of the appended claims.
