[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 7As shown, the vehicle protection plate assembly 100 of the embodiment of the present invention includes a front bumper lower guard plate 1 and a bottom guard plate 2, wherein the front bumper lower guard plate 1 includes a lower guard plate body 101, and the bottom guard plate 2 includes a bottom guard plate body 201. A first bending portion 102 is provided on one of the rear end of the lower guard plate body 101 and the front end of the bottom guard plate body 201, and a convex portion 202 is provided on the other of the rear end of the lower guard plate body 101 and the front end of the bottom guard plate body 201, which is convexly arranged and convexly arranged. On the projection plane orthogonal to the front and rear directions of the vehicle, the first bending portion 102 convexly projects upward, the convex portion 202 abuts against the first bending portion 102 in the up and down directions and is connected to the first bending portion 102, and the bottom surface of the lower guard plate body 101 and the bottom surface of the bottom guard plate body 201 smoothly transition.

[0032] A first bending portion 102 is provided on one of the rear end of the lower guard plate body 101 and the front end of the bottom guard plate body 201, and a protrusion 202 protruding upward is provided on the other of the rear end of the lower guard plate body 101 and the front end of the bottom guard plate body 201. It can be understood that the first bending portion 102 can be provided at the rear end of the lower guard plate, and the protrusion 202 is provided at the front end of the bottom guard plate body 201; or the first bending portion 102 is provided at the front end of the bottom guard plate body 201, and the protrusion 202 is provided at the rear end of the bottom guard plate body 201.

[0033] For example, Figure 4 and Figure 5 As shown, the first bending portion 102 is arranged at the rear end of the lower guard plate body 101, and the protrusion 202 is arranged at the front end of the bottom guard plate body 201. Since the first bending portion 102 is bent upwardly and the protrusion 202 is arranged to protrude upwardly, when the protrusion 202 is upwardly pressed against the first bending portion 102 and connected with the first bending portion 102, the first bending portion 102 and the protrusion 202 are both located on the upper side of the lower guard plate body 101 and the bottom guard plate body 201, avoiding the rear end of the lower guard plate body 101 and the front end of the bottom guard plate body 201 from overlapping and connecting to form a step structure, so that the bottom surface of the lower guard plate body 101 and the bottom surface of the bottom guard plate body 201 can smoothly transition. When the vehicle is driving, the air will not form turbulence and increase wind resistance due to unevenness at the overlap between the lower guard plate body 101 and the bottom guard plate body 201, thereby greatly reducing the wind resistance of the vehicle to save the energy consumption of the vehicle.

[0034] Therefore, the vehicle fender assembly 100 according to the embodiment of the present invention has advantages such as low wind resistance.

[0035] Optionally, the number of the first bending portions 102 and the protruding portions 202 are both multiple and one-to-one corresponding, and the first bending portions 102 are evenly spaced along the width direction of the vehicle, so that the force between the lower guard plate body 101 and the bottom guard plate body 201 is uniform after connection, which is beneficial to improving the connection stability between the lower guard plate body 101 and the bottom guard plate body 201.

[0036] In some embodiments, the first bent portion 102 is disposed at the rear end of the lower guard plate body 101, and the raised portion 202 is disposed at the front end of the bottom guard plate body 201. The first bent portion 102 has a first mounting hole 1021, and the raised portion 202 has a second mounting hole 2021. The first bent portion 102 and the raised portion 202 can be detachably connected by fasteners passed through the first mounting hole 1021 and the second mounting hole 2021.

[0037] like Figure 1 As shown, the first bending portion 102 and the protruding portion 202 can be detachably connected by bolts, or a spring nut can be provided on the first bending portion 102 to be connected with a screw, so that the structure between the first bending portion 102 and the protruding portion 202 is simple and the connection is convenient.

[0038] Optionally, the second mounting hole 2021 is a countersunk hole, which includes a large-diameter hole and a small-diameter hole, and the large-diameter hole is arranged closer to the bottom surface of the bottom guard plate body 201 than the small-diameter hole.

[0039] like Figure 2 As shown, when fasteners are used to connect the first mounting hole 1021 and the second mounting hole 2021, the fasteners can be passed through the small-diameter holes to connect with the first mounting hole 1021, and the bottom end of the fasteners can be placed in the large-diameter holes to prevent the fasteners from leaking out of the bottom surface of the bottom guard plate body 201 and causing an increase in wind resistance, which is further beneficial to reducing wind resistance and saving energy.

[0040] In some embodiments, a first reinforcing rib 103 is provided between the first bending portion 102 and the lower guard plate body 101 .

[0041] For example, Figure 4 As shown, there are multiple first reinforcing ribs 103, and the multiple first reinforcing ribs 103 are arranged at intervals along the width direction of the vehicle. Since the first bending portion 102 is a force-bearing position, stress concentration is prone to occur. The first reinforcing ribs 103 are arranged to strengthen and support the first bending portion 102, thereby preventing the first bending portion 102 from being deformed and losing its supporting function due to stress concentration.

[0042] In some embodiments, a second reinforcing rib 203 is provided between the protrusion 202 and the bottom guard plate body 201 .

[0043] For example, Figure 5 and Figure 6As shown, there are multiple second reinforcing ribs 203, and the multiple second reinforcing ribs 203 are evenly arranged around the protrusion 202. Since the protrusion 202 is a force-bearing position, stress concentration is prone to occur. By arranging the second reinforcing ribs 203, the protrusion 202 is strengthened and supported to prevent the protrusion from being deformed and losing its supporting function due to stress concentration.

[0044] In some embodiments, the front end of the bottom guard plate body 201 has an upwardly extending flange 204. In the front-to-rear direction of the vehicle, the flange 204 is provided with a first extension portion 205 extending toward the lower guard plate body 101. The first extension portion 205 stops downward on the lower guard plate body 101.

[0045] like Figure 5 and Figure 6 As shown, when assembling the bottom guard plate body 201, the first extension portion 205 can be first pressed downward against the lower guard plate body 101 to pre-assemble the bottom guard plate body 201, so as to adjust the relative position between the bottom guard plate body 201 and the lower guard plate body 101, thereby achieving rapid installation between the bottom guard plate body 201 and the lower guard plate body 101, which is beneficial to improving the assembly efficiency of the vehicle protective plate assembly 100 of the embodiment of the present invention.

[0046] In some embodiments, the rear end of the lower guard plate body 101 has a second bending portion 104 , and on a projection plane orthogonal to the front-rear direction of the vehicle, the second bending portion 104 protrudes upward, and the second bending portion 104 stops downward on the flange 204 .

[0047] like Figure 5 and Figure 6 As shown, when assembling the bottom guard plate body 201, the first extension part 205 can be firstly stopped downward on the bottom guard plate body 101, and then the second bent part 104 can be stopped upward on the flange 204, so that the first extension part 205 and the second bent part 104 can limit the bottom guard plate body 101 and the bottom guard plate body 201 in the up and down directions, so as to facilitate the rapid pre-assembly of the bottom guard plate body 101 and the bottom guard plate body 201, which is further conducive to improving the assembly efficiency of the vehicle protective plate assembly 100 of the embodiment of the present invention. In addition, after the connection between the bottom guard plate body 101 and the bottom guard plate body 201 is completed, it is also conducive to improving the assembly stability of the bottom guard plate body 101 and the bottom guard plate body 201.

[0048] Optionally, there are multiple first extension portions 205, and the multiple first extension portions 205 are arranged at intervals along the width direction of the vehicle, which is beneficial to increase the accuracy of the pre-positioning of the first extension portion 205 on the lower guard plate body 101, and further helps to improve the assembly efficiency of the vehicle protective plate assembly 100 of the embodiment of the present invention.

[0049] Optionally, there are multiple second bending portions 104, and the multiple second bending portions 104 are arranged at intervals along the width direction of the vehicle, which is beneficial to increase the accuracy of the pre-positioning of the first extension portion 205 on the lower guard plate body 101, and further helps to improve the assembly efficiency of the vehicle protective plate assembly 100 of the embodiment of the present invention.

[0050] In some embodiments, the vehicle protective plate assembly 100 of the embodiment of the present invention also includes a front bumper body 3, the rear end of the front bumper body 3 has a second extension portion 301, the second extension portion 301 extends along the front and rear direction of the vehicle toward the bottom guard plate body 201, the rear end of the bottom guard plate body 101 has a third extension portion 105, the third extension portion 105 extends along the front and rear direction of the vehicle toward the bottom guard plate body 201, the third extension portion 105 is located between the second extension portion 301 and the bottom guard plate body 201 in the up and down direction, and the second extension portion 301 is connected to the third extension portion 105.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, after the second extension part 301 and the third extension part 105 are connected to the vehicle guard plate assembly 100 of the embodiment of the present invention, the lower guard plate body 101 can be fixedly installed, and then the bottom guard plate body 201 can be assembled. Since the third extension part 105 is located between the second extension part 301 and the bottom guard plate body 201 in the up-down direction, when the bottom guard plate body 201 is installed, the third extension part 105 will not interfere with the bottom guard plate body 201, so that the lower guard plate body 101 is easy to install.

[0052] In some embodiments, the second extension portion 301 has a third mounting hole 3011 , and the third extension portion 105 has a fourth mounting hole 1051 . The second extension portion 301 and the third extension portion 105 can be detachably connected via fasteners passing through the third mounting hole 3011 and the fourth mounting hole 1051 .

[0053] For example, the second extension portion 301 and the third extension portion 105 may be detachably connected by bolts, or a leaf nut may be provided on the first extension portion 205 and connected to a screw, so that the second extension portion 301 and the third extension portion 105 have a simple structure and convenient connection.
