It should be understood that the detailed description is presented herein for purposes of illustration only and is not intended to limit the scope of the application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

For a better understanding of the front under-guard of the present utility model, a vehicle to which the front under-guard is applied will be described.

As shown in fig. 1 and 2, in some embodiments of the present disclosure, a vehicle 10 is provided that includes a body 11 and a front under-guard 12. The front lower guard plate 12 includes a guard plate body 100 and a plurality of first reinforcing ribs 200. The shield body 100 includes a front end 110 and a rear end 120 spaced apart from the front end 110, and the shield body 100 includes a first crush portion 130 and a second crush portion 140, the first crush portion 130 and the second crush portion 140 being spaced apart from the front end 110 in a width direction of the front end 110. The plurality of first reinforcing ribs 200 are fixed to the front end portion 110 at intervals in the width direction of the front end portion 110, and are disposed between the first crush portion 130 and the second crush portion 140, and the longitudinal direction of the first reinforcing ribs 200 extends in the direction from the front end portion 110 to the rear end portion 120. The front lower fender 12 is fixedly connected to the vehicle body 11 such that a portion of the fender body 100 is provided at the bottom of the vehicle body 11 and a portion of the fender body 100 is provided at the front face of the vehicle body 11.

When the vehicle 10 is assembled, the front lower guard plate 12 is fixedly connected with the vehicle body 11, so that part of the guard plate body 100 is arranged at the bottom of the vehicle body 11, and part of the guard plate body 100 is arranged at the front face of the vehicle body 11 to form a decorative effect. And the front lower fender 12 reinforces the supporting strength of the front end portion 110 of the fender body 100 by providing a plurality of first reinforcing ribs 200 on the fender body 100.

In this way, the front lower fender 12 can be provided at the bottom of the vehicle 10 during running of the vehicle 10, and can resist stone impact to protect the internal components of the vehicle 10. When the front lower guard plate 12 collides with a pedestrian in front and the collision force is small (for example, low-speed collision), the front end 110 of the front lower guard plate 12 collides with the lower leg of the pedestrian, the front end 110 of the front lower guard plate 12 is not easily damaged, and the lower leg of the pedestrian is cut by being inserted into the front lower guard plate 12, so that the damage of the front lower guard plate 12 can be reduced, and the maintenance cost of the vehicle 10 can be reduced. When the collision force is large (for example, medium-high speed collision), the guard plate body 100 breaks at the first crumple portion 130 and the second crumple portion 140, so that the guard plate body 100 that collides with the lower leg of the pedestrian is partially folded, the contact area between the lower leg of the pedestrian and the guard plate body 100 is increased, the collision pressure is reduced, and further the serious injury (for example, bone fracture or ligament fracture) of the lower leg of the pedestrian caused by the excessive collision pressure can be avoided, thereby reducing the injury to the pedestrian in the accident.

It can be appreciated that when the front lower guard plate 12 collides with other objects, the guard plate body 100 can also break through the first crumple portion 130 and the second crumple portion 140 under a larger collision force, so that the part of the guard plate body 100 that collides with other objects is folded, so as to increase the contact area between other objects and the guard plate body 100, reduce the collision pressure, and reduce the damage of the objects.

The term "front end 110" is to be understood in a broad sense and generally extends toward the front of the vehicle, and includes at least one of a front end, a front end surface, and a front region with respect to a rear end and a center portion.

Further, the "width direction of the front end portion 110" should be understood in a broad sense, being disposed substantially in the same direction as the width direction of the vehicle 10.

The term "rear end portion 120" is to be understood in a broad sense and generally extends toward the rear of the vehicle, and includes at least one of a rear end, a rear end face, and a rear region with respect to the front end and the middle.

Optionally, the first crush portion 130 is directly in front of the main drive location of the vehicle 10. The second crush section 140 is directly in front of the passenger's seat of the vehicle 10.

It should be noted that the specific implementation of the first crush portion 130 may be varied. For example, the thickness of the first crush portion 130 is smaller than the average thickness of the apron plate body, and the first crush portion 130 is provided with crush slots. The first crush portion 130 is provided with crush holes or the like.

As shown in fig. 2, in some embodiments, the first crush portion 130 and/or the second crush portion 140 includes a strength weakening recess 101 open to the apron body 100. In this way, the strength of the shield body 100 at the first crumple zone 130 and/or the second crumple zone 140 is reduced by providing the strength weakening concave portion 101, so that the design strength of the first crumple zone 130 and/or the second crumple zone 140 can be easily achieved, and the manufacturing difficulty of the shield body 100 can be reduced.

The specific implementation of the strength weakening recess 101 may be varied. For example, in some embodiments, the strength-weakening recess 101 comprises at least one of a blind hole, a through hole, a groove. In this way, at least one of a blind hole, a through hole, and a groove is formed in the shield body 100 to reduce the strength thereof, thereby forming the first crumple zone 130 and/or the second crumple zone 140.

On the basis of any of the above embodiments of the strength-weakening concave portion 101, as shown in fig. 2, in some embodiments, the strength-weakening concave portion 101 includes a plurality of portions and is provided at intervals in the width direction of the front end portion 110 to the apron body 100. In this way, the plurality of strength weakened portions are disposed on the panel body 100 at intervals along the width direction of the front end portion 110 to form the corresponding first crush portion 130, so as to flexibly adjust the crush range of the first crush portion 130. And/or, the plurality of strength weakening portions are arranged on the guard plate body 100 at intervals along the width direction of the front end portion 110 so as to form corresponding second crumple portions 140, so that crumple ranges of the second crumple portions 140 can be flexibly adjusted.

On the basis of any embodiment, as shown in fig. 2, in some embodiments, the plurality of first ribs 200 includes a plurality of first ribs 210 and at least one second rib 220, the second ribs 220 are disposed between two adjacent first ribs 210, and the second ribs 220 are provided with notches 221 to form a crumple zone on the protection plate body 100. In this way, the cross-sectional area of the front lower guard plate 12 in the gravity direction can be increased by the arrangement of the first ribs 210 and the second ribs 220, so as to increase the compressive strength of the guard plate body 100 in the thickness direction, and improve the plate bearing capacity of the guard plate body 100, so as to better bear other devices. The second ribs 220 are disposed between two adjacent first ribs 210, and the second ribs 220 are provided with notches 221 to form crumple zones on the guard plate body 100. Furthermore, when the vehicle 10 collides with the guard plate body 100 of the region where the lower leg of the pedestrian is located right in front of the first reinforcing rib 200, and the collision force is large (for example, medium-high speed collision), the guard plate body 100 will be partially bent at the crumple zone formed by the second rib 220, so as to increase the contact area between the lower leg of the pedestrian and the guard plate body 100, reduce the collision pressure, and further avoid the serious injury (for example, bone fracture or ligament fracture) of the lower leg of the pedestrian caused by the excessive collision pressure, thereby reducing the injury to the pedestrian in the accident.

As can be appreciated, the first reinforcing rib 200 is disposed between the first crush portion 130 and the second crush portion 140, and the second rib 220 is disposed between two adjacent first ribs 210, so that the second rib 220 can be disposed at a distance from the first crush portion 130 and/or the second crush portion 140. In this way, when the front position of the front lower guard 12 collides with the pedestrian is between the right front of the first crumple portion 130 and the right front of the crumple zone, the first crumple portion 130 and the crumple zone are crumpled, so that the guard body 100 in this area is folded, to increase the contact area between the lower leg of the pedestrian and the guard body 100, and reduce the collision pressure. And/or, when the front position of the front lower guard 12 collides with the pedestrian is between the right front of the second crumple portion 140 and the right front of the crumple zone, the second crumple portion 140 and the crumple zone crumple, so that the guard body 100 in the area bends, the contact area between the lower leg of the pedestrian and the guard body 100 is increased, and the collision pressure is reduced.

It should be noted that the number of "crush zones" may be selected according to actual needs. For example, in some embodiments, at least two crush zones are disposed in the widthwise middle of the apron body 100. That is, at least two crumple zones are provided in the middle of the width direction of the vehicle 10. In this manner, it is advantageous to improve the collision test performance of the vehicle 10.

In addition, the specific locations of the "first crush section 130", "second crush section 140" and "crush zone" may be flexibly set according to actual needs.

For example, in some embodiments, the first crush portion 130 is disposed in the 1/4 impact zone of the vehicle 10 in the width direction and is disposed directly opposite the primary driver's seat. In this manner, it is advantageous to improve the collision test performance of the vehicle 10.

In some embodiments, the second crush section 140 is disposed in the 1/4 impact zone of the vehicle 10 in the width direction and is disposed directly opposite the passenger's seat. In this manner, it is advantageous to improve the collision test performance of the vehicle 10.

On the basis of any of the above embodiments, as shown in fig. 2, in some embodiments, the front lower protecting plate 12 further includes a buffering energy absorbing portion 300, where the buffering energy absorbing portion 300 is fixedly disposed on the protecting plate body 100 and disposed between the first reinforcing rib 200 and the rear end portion 120, and the buffering energy absorbing portion 300 is disposed near the first reinforcing rib 200. Thus, during the running of the vehicle 10, when the front lower fender 12 collides with a pedestrian in front, and the collision force is large (for example, medium-high speed collision), the fender body 100 breaks at the first crumple portion 130 and the second crumple portion 140, so that the part of the fender body 100 colliding with the calf of the pedestrian is folded, the contact area between the calf of the pedestrian and the fender body 100 is increased, the collision pressure is reduced, and further the serious injury (for example, bone fracture or ligament fracture, etc.) of the calf of the pedestrian caused by the excessive collision pressure can be avoided. And meanwhile, collapse energy absorption is realized in collision. When the collision force is applied after the first crumple zone 130 and the second crumple zone 140 crumple, the buffer energy absorbing portion 300 absorbs energy and deforms to further absorb collision energy, thereby improving the collision performance of the front lower fender 12.

Further, in some embodiments, the buffering and energy absorbing portion 300 includes a first buffering strip 310 and a second buffering strip 320 which are fixed to the guard plate body 100 in a crossing manner, wherein a length direction of the first buffering strip 310 is set along a width direction of the front end portion 110, and a length direction of the second buffering strip 320 extends along the width direction of the front end portion 110. In this manner, the first and second bumper strips 310 and 320 can be deformed by crossing to achieve the cushioning and energy absorption.

Specifically, when the front lower fender 12 collides with a pedestrian in front and the collision force is large (for example, a medium-high speed collision), the fender body 100 breaks at the first crumple portion 130 and the second crumple portion 140, so that the portion of the fender body 100 that collides with the lower leg of the pedestrian is folded to increase the contact area of the lower leg of the pedestrian with the fender body 100, reduce the collision pressure, and simultaneously realize crumple energy absorption in the collision. After the first crumple zone 130 crumples with the second crumple zone 140, the deformation of the first buffer strip 310 and the second buffer strip 320 arranged in a crossing manner continues to absorb the collision energy, so as to further improve the collision performance of the front lower guard plate 12.

In addition, the length direction of the first buffer strip 310 is along the width direction of the front end 110, and the length direction of the second buffer strip 320 is along the width direction of the front end 110, so that the sides of the first buffer strip 310 and the second buffer strip 320 are in contact with the lower leg of the pedestrian, the contact area is increased, and the broken parts of the first buffer strip 310 and the second buffer strip 320 can avoid the front of the lower leg of the pedestrian, thereby protecting the pedestrian and reducing the injury to the pedestrian in the accident.

Optionally, the first buffer strip 310 and the second buffer strip 320 are plate-shaped and are disposed perpendicular to the guard plate body 100. Thus, the cross-sectional area of the front lower guard plate 12 in the gravity direction can be increased, so that the compressive strength of the guard plate body 100 in the thickness direction can be increased, and the plate bearing capacity of the guard plate body 100 can be improved, so that other devices can be better borne.

Further, as shown in FIG. 2, in some embodiments, the cushioned energy absorber 300 further includes at least two connectors 330 that are secured to the apron body 100 at intervals. One end of the first buffer bar 310 is fixedly connected with one of the connectors 330, the other end is fixedly connected with the other connector 330, one end of the second buffer bar 320 is fixedly connected with one of the connectors 330, and the other end is fixedly connected with the other connector 330 to form at least two triangular buffer areas. In this way, the first buffer strip 310, the second buffer strip 320 and the connecting body 330 cooperate to form a triangular buffer area, so that a stable triangular structure is formed, and then the first buffer strip 310 and the second buffer strip 320 can deform and absorb more collision energy, and then collapse and break, so that the energy absorbing effect of the buffering energy absorbing part 300 can be improved.

In combination with the above embodiments, as shown in fig. 2, in some embodiments, the front lower panel 12 further includes a mounting portion 150 for mounting the impact beam, the mounting portion 150 and the buffering energy absorbing portion 300 are disposed at intervals along the direction from the front end portion 110 to the rear end portion 120, the front lower panel 12 includes a second reinforcing rib 400 fixedly disposed on the panel body 100, and a length direction of the second reinforcing rib 400 extends along the direction from the connector 330 to the mounting portion 150. In this way, the buffer energy absorbing portion 300, the mounting portion 150 and the second reinforcing rib 400 form another crumple energy absorbing structure to absorb energy generated by collision as completely as possible, so that the front lower guard plate 12 of the present application can protect pedestrians and also give consideration to collision performance.

Further, the mounting portion 150 and the second reinforcing rib 400 can function as a shank protective beam. And then compare with traditional front guard plate assembly, vehicle 10 of this application need not extra shank protection roof beam and carries out the energy-absorbing, is favorable to practicing thrift the cost.

Specifically, during the running of the vehicle 10, when the front lower fender 12 collides with a pedestrian in front, and the collision force is large (for example, a medium-high speed collision), the fender body 100 collapses and absorbs energy in the first collapsing portion 130 and the second collapsing portion 140, and then absorbs energy through the buffer energy absorbing portion 300. If there is a collision force, the mounting portion 150 and the second reinforcing rib 400 absorb energy and deform to further absorb collision energy, thereby improving the collision performance of the front under-panel 12.

In some embodiments, at least two second reinforcing ribs 400 are spaced apart in a group and are in one-to-one correspondence with the mounting portions 150.

On the basis of any of the above embodiments, as shown in fig. 2, in some embodiments, the guard plate body 100 further includes a decoration body 12a, where the decoration body 12a is fixedly disposed at the front end 110 and protrudes out of the guard plate body 100. Thus, when the vehicle 10 is assembled, the front under-fender 12 is fixedly connected to the vehicle body 11 such that a portion of the fender body 100 is provided at the bottom of the vehicle body 11 and the decorative body 12a is provided at the front face of the vehicle body 11, thereby forming a decorative effect. The front lower guard plate 12 further has a decorative function, and the vehicle 10 is more attractive in appearance when seen from the bottom of the vehicle under the lifter.

On the basis of any of the above embodiments, as shown in fig. 3, in some embodiments, the front lower fender 12 further includes a mounting portion 150 for mounting the impact beam, and the mounting portion 150 is spaced from the first reinforcing bead 200 in a direction from the front end portion 110 to the rear end portion 120. The mounting portion 150 includes a mounting hole 151, and a portion of the mounting hole 151 is disposed toward the rear end 120 and has a partially elliptical cone shape. In this way, the impact beam is easily mounted to the front lower fender 12 through the mounting hole 151. And a portion of the mounting hole 151 is disposed toward the rear end 120 and has a partially elliptical cone shape, so that it is possible to reduce or avoid the formation of vortex in the region of the mounting portion 150 during high-speed running, which is advantageous in improving the windage coefficient of the vehicle 10.

In some embodiments, the mounting holes 151 each have a 3mm play in the width direction (e.g., X direction) and the length direction (e.g., Y direction) of the shield body 100. In this way, even if there is a manufacturing error in the parts, it is still ensured that the fasteners (including but not limited to the screw assembly) and the mounting holes 151 do not have a misalignment, thereby achieving the fixation of the impact beam and the fender body 100.
