Therefore, it is necessary to improve the vehicle structure to overcome the above-mentioned problems.

Utility Model Content

The utility model provides a vehicle structure, which can increase the ability of the vehicle structure to withstand collision loads.

The utility model provides a vehicle structure, comprising: a frame structure, comprising a frame component, the frame components are respectively arranged on both sides of the vehicle in the width direction and extend along the front-rear direction of the vehicle; a bumper component is arranged at the end of the frame structure in the front-rear direction and extends along the width direction; an assembly component is arranged on the outer side of the frame structure in the width direction and extends along the front-rear direction, and extends obliquely toward the bumper component toward the inner side of the vehicle in the width direction; a cross beam is arranged on the frame structure; and an impact absorbing component is arranged at the end of the cross beam in the width direction and extends toward the assembly component, one end of the impact absorbing component is fixed to the cross beam, the other end of the impact absorbing component is a free end, the other end of the impact absorbing component is closer to the outer side of the vehicle in the width direction than the frame structure, and the position of the other end of the impact absorbing component in the up-down direction of the vehicle overlaps with the assembly component.

In an embodiment of the present invention, the end of the frame component faces the bumper component, the end of the frame component is connected to the bumper component, the end of the assembly component faces the bumper component, and the end of the assembly component is connected to the bumper component.

In an embodiment of the present invention, the vehicle structure further comprises a connection portion, and the end of the frame component and the end of the assembly component are connected to each other through the connection portion.

In an embodiment of the present invention, the connection portion is located inwardly of an outer end portion of the bumper component in the width direction in the width direction.

In an embodiment of the present invention, the other end of the impact absorbing member and an inner side surface of the assembling member in the width direction are opposed to each other.

In an embodiment of the present invention, the one end of the impact absorbing component is fixed to the frame structure together with the cross beam.

Based on the above, in the vehicle structure of the utility model, an impact absorbing part is provided at the end of the crossbeam, and the impact absorbing part has a free end, and the free end is inclined toward the assembly component outside the crossbeam. Accordingly, when the vehicle is subjected to a large-area forward collision in the front-to-back direction, the collision load can be prevented from being transmitted from the assembly component to the frame component via the impact absorbing part, thereby preventing the frame component from being stretched and deformed in an unexpected direction, so that the frame component can smoothly produce axial extrusion to absorb the collision load well when the collision occurs. In addition, the impact absorbing part is fixed to the crossbeam, and the frame component can be formed into a straight line as much as possible, which is conducive to the axial extrusion of the frame component. Moreover, when the vehicle is subjected to a small-area offset collision in the front-to-back direction, the collision load can be transmitted to the free end of the impact absorbing part via the assembly component, and then transmitted to the crossbeam and the frame component via the impact absorbing part. In this process, the collision load acts on the crossbeam in the width direction through the rotation of the impact absorbing part, thereby causing the vehicle to be displaced in the direction away from the collision object through the reaction force of the crossbeam, thereby preventing the collision object from entering the interior of the vehicle body, thereby achieving the effect of protecting the passengers in the vehicle. Since the vehicle structure of the present invention can increase the ability of the vehicle structure to withstand collision loads as described above, there is no need to additionally provide structural reinforcement ribs and/or structural reinforcement members, and the vehicle body can have a smaller weight.

In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below and described in detail with reference to the accompanying drawings.

Detailed ways

FIG. 1 is a partial top view of a vehicle structure of an embodiment of the present utility model. FIG. 2 is a perspective view of some components of the vehicle structure of FIG. 1 . FIG. 3 is a side view of some components of the vehicle structure of FIG. 2 . Referring to FIG. 1 to FIG. 3 , the vehicle structure 100 of the present embodiment includes a frame structure 110, a bumper component 120, an assembly component 130, a cross beam 140, and an impact absorbing component 150. The frame structure 110 includes two frame components 112 (one of the frame components 112 is shown in the figure to make the figure more concise), and the two frame components 112 are respectively arranged on both sides of the vehicle in the width direction (parallel to the axial direction Y) and extend along the front-to-back direction of the vehicle (parallel to the axial direction X). The bumper component 120 is arranged at the end of the frame structure 110 in the front-to-back direction of the vehicle and extends along the width direction of the vehicle, and is connected to the frame structure 110 and the assembly component 130 through a connecting structure 122. The axial direction X may be the forward direction or the backward direction of the vehicle, that is, the bumper component 120 may be the front bumper of the vehicle or the rear bumper of the vehicle, and the present invention is not limited thereto.

The assembly component 130 is arranged on the outer side of the frame structure 110 in the width direction of the vehicle and extends in the front-rear direction of the vehicle. As shown in FIG. 1 , the assembly component 130 is curved and extends obliquely toward the bumper component 120 toward the inner side of the vehicle in the width direction. The cross beam 140 is arranged on the frame structure 110 and extends in the width direction of the vehicle. The impact absorbing component 150 is arranged at the end of the cross beam 140 in the width direction of the vehicle and extends toward the assembly component 130. Specifically, one end 1501 of the impact absorbing component 150 is fixed to the cross beam 140, and the other end 1502 of the impact absorbing component 150 is a free end. The other end 1502 of the impact absorbing component is closer to the outer side of the vehicle in the width direction than the frame structure 110, and the position of the other end 1502 of the impact absorbing component 150 in the up-down direction of the vehicle (the direction parallel to the axial direction Z) overlaps with the assembly component 130.

As described above, in the vehicle structure 100 of the present embodiment, the impact absorbing part 150 is provided at the end of the cross beam 140, and the impact absorbing part 150 has a free end, and the free end is inclined toward the assembly part 130 outside the cross beam 140. Accordingly, when the vehicle is subjected to a large-area forward collision in the front-to-back direction, the collision load L1 can be prevented from being transmitted from the assembly part 130 to the frame part 112 via the impact absorbing part 150, thereby preventing the frame part 110 from being stretched and deformed in an unexpected direction, so that the frame part 112 can smoothly generate axial (parallel to the axial direction X) extrusion when the collision occurs to absorb the collision load L1 well. In addition, the impact absorbing part 150 is fixed to the cross beam 140, and the frame part 112 can be formed into a straight line as much as possible, which is conducive to the axial extrusion of the frame part 112. Furthermore, when the vehicle is subjected to a small-area offset collision in the front-rear direction, the collision load L2 can be transmitted to the free end of the impact absorbing component 150 via the assembly component 130, and then transmitted to the cross beam 140 and the frame component 112 via the impact absorbing component 150. In this process, the collision load L2 acts on the cross beam 140 along the width direction through the rotation of the impact absorbing component 150 along the rotation direction R, and then the vehicle is displaced in a direction away from the collision object by the reaction force of the cross beam 140, so as to prevent the collision object from entering the interior of the vehicle body, thereby protecting the occupants in the vehicle. Since the vehicle structure 100 of this embodiment can increase the ability of the vehicle structure 100 to withstand the collision load as described above, it is not necessary to additionally set up structural reinforcement ribs and/or structural reinforcement members, and the vehicle body can have a smaller weight.

Please refer to FIG. 1 . In this embodiment, the end 1121 of the frame member 112 faces the bumper member 120, and the end 1121 of the frame member 112 is connected to the bumper member 120. That is, the end 1121 of the frame member 112 in the collision load direction is connected to the bumper member 120. Similarly, the end 1301 of the assembly member 130 faces the bumper member 120, and the end 1301 of the assembly member 130 is connected to the bumper member 120. That is, the end 1301 of the assembly member 130 in the collision load direction is connected to the bumper member 120. Accordingly, when the vehicle is subjected to a large-area forward collision in the front-rear direction, the frame member 112 can effectively generate axial compression through the rotation of the impact absorbing member 150, and the assembly member 130 can effectively receive the collision force from the bumper member 120 and deform to absorb the impact.

The vehicle structure 100 of the present embodiment further includes a connection portion 160. The end 1121 of the frame member 112 and the end 1301 of the assembly member 130 are connected to each other through the connection portion 160. By connecting the end 1121 of the frame member 112 and the end 1301 of the assembly member 130 to each other through the connection portion 160 as described above, the collision load of the bumper member 120 can be reliably distributed to the frame member 112 and the assembly member 130. Further, in the present embodiment, the connection portion 160 is located on the inner side of the outer end portion 1201 of the bumper member 120 in the width direction of the vehicle. Accordingly, the collision load from the bumper member 120 can be reliably transmitted to the frame member 112 and the assembly member 130 at the connection portion 160. FIG. 1 schematically illustrates the connection portion 160 . The connection portion 160 may actually be any suitable connection structure and connect the end 1121 of the frame component 112 and the end 1301 of the assembly component 130 in any suitable manner, and the present invention is not limited thereto.

FIG4 is a three-dimensional view of a part of the vehicle structure of FIG2 from another perspective. Referring to FIG4 , in this embodiment, the other end 1502 of the impact absorbing component 150 and the inner side surface 130a of the assembly component 130 in the width direction of the vehicle are opposite to each other. Accordingly, when the vehicle is subjected to a small-area offset collision in the front-to-back direction, the other end 1502 of the impact absorbing component 150 and the inner side surface 130a of the assembly component 130 can contact each other, so that the load when the assembly component 130 deforms inward can be smoothly and reliably transmitted to the crossbeam 140 through the impact absorbing component 150. In addition, the one end 1501 of the impact absorbing component 150 of this embodiment is fixed to the frame component 112 of the frame structure 110 together with the crossbeam 140 through the fixing member 170. Specifically, the fixing member 170 is, for example, a screw member, which passes through the one end 1501 of the impact absorbing member 150 and the cross beam 140 and screws and fixes the one end 1501 of the impact absorbing member 150 and the cross beam 140 to the frame member 112. Accordingly, the load transmitted to the impact absorbing member 150 via the assembly member 130 can be reliably distributed to the cross beam 140 and the frame member 112.

In summary, in the vehicle structure of the utility model, an impact absorbing part is provided at the end of the crossbeam, and the impact absorbing part has a free end, and the free end is inclined toward the assembly component outside the crossbeam. Accordingly, when the vehicle is subjected to a large-area forward collision in the front-to-back direction, the collision load can be prevented from being transmitted from the assembly component to the frame component via the impact absorbing part, thereby preventing the frame component from being stretched and deformed in an unexpected direction, so that the frame component can smoothly produce axial extrusion to absorb the collision load well when the collision occurs. In addition, the impact absorbing part is fixed to the crossbeam, and the frame component can be formed into a straight line as much as possible, which is conducive to the axial extrusion of the frame component. Moreover, when the vehicle is subjected to a small-area offset collision in the front-to-back direction, the collision load can be transmitted to the free end of the impact absorbing part via the assembly component, and then transmitted to the crossbeam and the frame component via the impact absorbing part. In this process, the collision load acts on the crossbeam in the width direction through the rotation of the impact absorbing part, thereby causing the vehicle to be displaced in the direction away from the collision object through the reaction force of the crossbeam, thereby preventing the collision object from entering the interior of the vehicle body, thereby achieving the effect of protecting the passengers in the vehicle. Since the vehicle structure of the present invention can increase the ability of the vehicle structure to withstand collision loads as described above, there is no need to additionally provide structural reinforcement ribs and/or structural reinforcement members, and the vehicle body can have a smaller weight.
