Accordingly, there is a need for an improvement in vehicle construction that overcomes the above-described problems.
Disclosure of utility model
The present utility model provides a vehicle structure that can increase the capability of the vehicle structure to withstand collision loads.
The present utility model provides a vehicle structure including: a frame structure including frame members that are respectively arranged on both sides of a vehicle in a width direction and extend in a front-rear direction of the vehicle; a bumper member disposed at an end portion of the frame structure in the front-rear direction and extending in the width direction; an assembly member disposed outside the frame structure in the width direction and extending in the front-rear direction, and extending obliquely toward the bumper member toward the inside of the vehicle in the width direction; a cross beam disposed on the frame structure; and an impact absorbing member disposed at an end of the cross member in the width direction and extending toward the assembly member, one end of the impact absorbing member being fixed to the cross member, the other end of the impact absorbing member being a free end, the other end of the impact absorbing member being closer to an outer side of the vehicle in the width direction than the frame structure, and the other end of the impact absorbing member being overlapped with the assembly member at a position in an up-down direction of the vehicle.
In an embodiment of the utility model, the end of the frame member is directed towards the bumper member, the end of the frame member is connected to the bumper member, the end of the assembly member is directed towards the bumper member, and the end of the assembly member is connected to the bumper member.
In an embodiment of the utility model, the vehicle structure further includes a connecting portion by which the end of the frame member and the end of the assembly member are connected to each other.
In an embodiment of the utility model, the connecting portion is located inside an outer end portion of the bumper member in the width direction.
In an embodiment of the present utility model, the other end of the impact absorbing member and an inner side surface of the assembly member in the width direction are opposed to each other.
In an embodiment of the utility model, the one end of the impact absorbing member is fixed to the frame structure together with the cross member.
In view of the above, in the vehicle structure of the present utility model, the impact absorbing portion is provided at the end portion of the cross member, and the impact absorbing portion has a free end that is inclined toward the assembly member outside the cross member. Accordingly, when the vehicle receives a large-area forward collision in the front-rear direction, the collision load can be prevented from being transmitted from the assembly member to the frame member via the impact absorbing member, and further, the frame member is prevented from being deformed in an unintended direction, so that the frame member can smoothly generate axial compression to well absorb the collision load when the collision occurs. Furthermore, the impact absorbing portion is fixed to the cross member, and the frame member can be formed as straight as possible, thereby facilitating the axial compression of the frame member. When the vehicle is subjected to offset small-area collision in the front-rear direction, collision load can be transmitted to the free end of the impact absorbing component through the assembling component, and then transmitted to the cross beam and the frame component through the impact absorbing component, in the process, the collision load acts on the cross beam along the width direction through the rotation of the impact absorbing component, and then the vehicle is enabled to generate displacement along the direction away from the collided object through the reaction force of the cross beam, so that the collided object is prevented from entering the vehicle body, and the effect of protecting passengers in the vehicle is achieved. Since the vehicle structure of the present utility model can increase the capability of the vehicle structure to withstand collision load as described above, no additional structural reinforcement and/or structural reinforcement is required, and the vehicle body can have a smaller weight.
In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description
FIG. 1 is a partial top view schematic illustration of a vehicle structure according to one embodiment of the utility model. Fig. 2 is a perspective view of a portion of the components of the vehicle structure of fig. 1. Fig. 3 is a side view of a portion of the components of the vehicle structure of fig. 2. Referring to fig. 1 to 3, the vehicle structure 100 of the present embodiment includes a frame structure 110, a bumper member 120, an assembly member 130, a cross member 140, and an impact absorbing member 150. The frame structure 110 includes two frame members 112 (for brevity, one of the frame members 112 is shown in the drawing), and the two frame members 112 are respectively disposed on both sides of the vehicle in the width direction (the direction parallel to the axial direction Y) and extend in the front-rear direction (the direction parallel to the axial direction X) of the vehicle. The bumper member 120 is disposed at an end portion of the frame structure 110 in the front-rear direction of the vehicle and extends in the width direction of the vehicle, and is connected to the frame structure 110 and the assembly member 130 by a connection structure 122. The axial direction X may be a forward direction or a backward direction of the vehicle, that is, the bumper member 120 may be a front bumper of the vehicle or a rear bumper of the vehicle, to which the present utility model is not limited.
The assembly member 130 is disposed outside 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 member 130 is curved and extends obliquely inward in the width direction of the vehicle toward the bumper member 120. The cross member 140 is disposed on the frame structure 110 and extends in the width direction of the vehicle. The impact absorbing member 150 is disposed at an end of the cross member 140 in the width direction of the vehicle and extends toward the assembly member 130. Specifically, one end 1501 of the impact absorbing member 150 is fixed to the cross member 140, and the other end 1502 of the impact absorbing member 150 is a free end. The other end 1502 of the impact absorbing member 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 member 150 in the up-down direction of the vehicle (direction parallel to the axial direction Z) overlaps the assembly member 130.
As described above, in the vehicle structure 100 of the present embodiment, the impact absorbing portion 150 is provided at the end of the cross member 140, and the impact absorbing portion 150 has the free end that is inclined toward the assembly member 130 outside the cross member 140. Accordingly, when the vehicle receives a large-area forward collision in the front-rear direction, the collision load L1 can be prevented from being transmitted from the assembly member 130 to the frame member 112 via the impact absorbing member 150, and further, the frame member 110 is prevented from being deformed in an unintended direction, so that the frame member 112 can smoothly generate an axial direction (a direction parallel to the axial direction X) compression to absorb the collision load L1 well when the collision occurs. In addition, the impact absorbing portion 150 is fixed to the cross member 140, and the frame member 112 can be formed as straight as possible, thereby facilitating the axial compression of the frame member 112. When the vehicle receives a small-area offset collision in the front-rear direction, the collision load L2 is transmitted to the free end of the impact absorbing member 150 via the assembly member 130, and is further transmitted to the cross member 140 and the frame member 112 via the impact absorbing member 150, and in this process, the collision load L2 is caused to act on the cross member 140 in the width direction by the rotation of the impact absorbing member 150 in the rotation direction R, and the vehicle is further caused to displace in a direction away from the collided object by the reaction force of the cross member 140, so that the collided object is prevented from entering the vehicle body, and the effect of protecting the occupant in the vehicle is achieved. Since the vehicle structure 100 of the present embodiment can increase the capability of the vehicle structure 100 to withstand the collision load as described above, no additional structural reinforcement and/or structural reinforcement is required, and the vehicle body can have a smaller weight.
Referring to fig. 1, in the present 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 is directed towards the bumper member 120, said end 1301 of the assembly member 130 being 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 undergoes a large-area forward collision in the front-rear direction, the frame member 112 can effectively generate an axial crush by the rotation of the impact absorbing member 150, and the assembly member 130 can effectively receive a collision force from the bumper member 120 to deform to absorb an impact.
The vehicle structure 100 of the present embodiment further includes a connecting portion 160. The end 1121 of the frame member 112 and the end 1301 of the assembly member 130 are connected to each other by a connection portion 160. Connecting the end 1121 of the frame member 112 and the end 1301 of the assembly member 130 to each other by the connecting portion 160 as described above allows the collision load of the bumper member 120 to be reliably distributed to the frame member 112 and the assembly member 130. Further, in the present embodiment, the connecting portion 160 is located inside 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 connecting portion 160. The connection portion 160 is schematically illustrated in fig. 1, and the connection portion 160 may be actually of various suitable connection structures, and may connect the end 1121 of the frame member 112 and the end 1301 of the assembly member 130 in various suitable manners, which is not limited by the present utility model.
Fig. 4 is a perspective view of a portion of the components of the vehicle structure of fig. 2 from another perspective. Referring to fig. 4, in the present embodiment, the other end 1502 of the impact absorbing member 150 and the inner side surface 130a of the assembly member 130 in the width direction of the vehicle face each other. Accordingly, when the vehicle receives a small-area collision with a misalignment in the front-rear direction, the other end 1502 of the shock absorbing member 150 and the inner side surface 130a of the assembly member 130 can be brought into contact with each other, so that the load when the assembly member 130 is deformed inward can be smoothly transmitted to the cross member 140 through the shock absorbing member 150. Further, the one end 1501 of the impact absorbing member 150 of the present embodiment is fixed to the frame member 112 of the frame structure 110 together with the cross member 140 by the fixing member 170. Specifically, the fixing member 170 is, for example, a screw lock member that passes through the one end 1501 of the impact absorbing member 150 and the cross member 140 and screw-locks the one end 1501 of the impact absorbing member 150 together with the cross member 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 member 140 and the frame member 112.
As described above, in the vehicle structure of the present utility model, the impact absorbing portion is provided at the end portion of the cross member, and the impact absorbing portion has the free end that is inclined toward the assembly member outside the cross member. Accordingly, when the vehicle receives a large-area forward collision in the front-rear direction, the collision load can be prevented from being transmitted from the assembly member to the frame member via the impact absorbing member, and further, the frame member is prevented from being deformed in an unintended direction, so that the frame member can smoothly generate axial compression to well absorb the collision load when the collision occurs. Furthermore, the impact absorbing portion is fixed to the cross member, and the frame member can be formed as straight as possible, thereby facilitating the axial compression of the frame member. When the vehicle is subjected to offset small-area collision in the front-rear direction, collision load can be transmitted to the free end of the impact absorbing component through the assembling component, and then transmitted to the cross beam and the frame component through the impact absorbing component, in the process, the collision load acts on the cross beam along the width direction through the rotation of the impact absorbing component, and then the vehicle is enabled to generate displacement along the direction away from the collided object through the reaction force of the cross beam, so that the collided object is prevented from entering the vehicle body, and the effect of protecting passengers in the vehicle is achieved. Since the vehicle structure of the present utility model can increase the capability of the vehicle structure to withstand collision load as described above, no additional structural reinforcement and/or structural reinforcement is required, and the vehicle body can have a smaller weight.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
