[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 8 A vehicle 100 according to an embodiment of the present invention is described.

[0038] Combination Figure 1-Figure 5 As shown, the vehicle 100 according to the utility model can mainly include: a bumper 10, an anti-collision beam 20 and an auxiliary mounting bracket. Among them, the anti-collision beam 20 is extended in the left-right direction and connected to the rear of the bumper 10, and the auxiliary mounting bracket assembly 30 includes: a first auxiliary mounting bracket 31 and a second auxiliary mounting bracket 32, the first auxiliary mounting bracket 31 is arranged in front of the anti-collision beam 20 and connected between the anti-collision beam 20 and the bumper 10, and the second auxiliary mounting bracket 32 ​​is arranged behind the anti-collision beam 20 and connected between the anti-collision beam 20 and the bumper 10.

[0039] Specifically, the bumper 10, as a component for protecting the vehicle 100, is arranged in front of the anti-collision beam 20 and connected to the anti-collision beam 20, so as to realize the installation setting of the bumper 10 on the vehicle 100, so that the bumper 10 is located at the front end of the vehicle 100, so that the bumper 10 can play a role in protecting the vehicle body and pedestrian safety.

[0040] Since the anti-collision beam 20 needs to meet the regulatory requirements for safe collision, the anti-collision beam 20 should shrink and absorb energy during the collision. Therefore, the thickness of the anti-collision beam 20 should not be designed to be too large, which will cause the anti-collision beam 20 to have a low stiffness. During the driving of the vehicle 100, the excitation from the road surface can easily cause the bumper 10 to twist around the length of the anti-collision beam 20, and even resonate and cause fatigue damage. It can be understood that the left and right direction is the extension direction of the anti-collision beam 20, that is, the length direction of the anti-collision beam 20. The twisting of the bumper 10 around the length of the anti-collision beam 20 is: the twisting of the bumper 10 around the left and right direction.

[0041] By setting up the auxiliary mounting bracket assembly 30, the first auxiliary mounting bracket 31 is set in front of the anti-collision beam 20 and connected between the anti-collision beam 20 and the bumper 10, and the second auxiliary mounting bracket 32 ​​is set behind the anti-collision beam 20 and connected between the anti-collision beam 20 and the bumper 10. In this way, the bumper 10 can establish a connection relationship both in front of and behind the anti-collision beam 20, so that a mutually pulling structural layout is formed between the bumper 10 and the anti-collision beam 20, and a sufficient and reliable connection relationship is established between the bumper 10 and the anti-collision beam 20. Therefore, without changing the size and structure of the anti-collision beam 20 to meet the safety collision, the torsion of the bumper 10 around the left and right directions can be suppressed, and the vibration mode of the bumper 10 can be improved.

[0042] Therefore, by setting the first auxiliary mounting bracket 31 in front of the anti-collision beam 20 and connecting between the anti-collision beam 20 and the bumper 10, and setting the second auxiliary mounting bracket 32 ​​behind the anti-collision beam 20 and connecting between the anti-collision beam 20 and the bumper 10, a mutually pulling structural layout can be formed between the bumper 10 and the anti-collision beam 20, so that without changing the size and structure of the anti-collision beam 20 to meet the safety collision, the torsion of the bumper 10 in the left and right directions can be suppressed, the vibration mode of the bumper 10 can be improved, and the driving performance of the vehicle 100 can be improved.

It is only necessary to make at least a part of the first plate portion 311 fit and connect and fix with the bumper 10, and make the lower end of the first plate portion 311 fit and connect and fix with the anti-collision beam 20, so as to realize the connection and fixation between the first auxiliary mounting bracket 31 and the bumper 10 and the anti-collision beam 20 respectively, and make the first auxiliary mounting bracket 31 be located on the upper front side of the anti-collision beam 20.

[0045] Optionally, in some embodiments of the present invention, combined with Figure 3 and Figure 4As shown, the second plate portion 312 is provided with a snap-fit ​​buckle 3121, and the bumper 10 is provided with a snap-fit ​​hole 112. The snap-fit ​​buckle 3121 and the snap-fit ​​hole 112 are snap-fitted to achieve the connection and fixation between the first auxiliary mounting bracket 31 and the bumper 10. In addition, a first through hole 3111 can be provided on the first plate portion 311, and a second through hole can be provided on the anti-collision beam 20. The first through hole 3111 and the second through hole correspond to each other and are connected and fixed by fasteners, so that the connection and fixation between the first auxiliary mounting bracket 31 and the anti-collision beam 20 can be achieved. The fasteners include but are not limited to bolts.

[0046] Of course, the connection between the second plate portion 312 and the bumper 10 , and the connection between the first plate portion 311 and the anti-collision beam 20 , may also be by other means such as welding, which are not specifically limited here.

[0048] Combination Figure 3 and Figure 5 As shown, an anti-collision beam reinforcement plate 21 is arranged on the rear side of the anti-collision beam 20, and the second auxiliary mounting bracket 32 ​​can mainly include: a third plate portion 321 and a fourth plate portion 322, the third plate portion 321 is extended in the up and down directions, one end of the fourth plate portion 322 is connected to the upper end of the third plate portion 321, and the other end of the fourth plate portion 322 is extended toward the front, the lower end of the third plate portion 321 is connected to a second connection portion 323 extending toward the rear, and the front end of the fourth plate portion 322 is connected to a third connection portion 324 extending upward, the second connection portion 323 is fitted and fixed to the bumper 10, and the third connection portion 324 is fitted and fixed to the anti-collision beam reinforcement plate 21.

[0049] In this way, the third plate portion 321, the fourth plate portion 322, the second connecting portion 323 and the third connecting portion 324 can form the overall structure of the second auxiliary mounting bracket 32, so that the second auxiliary mounting bracket 32 ​​can adapt to the relative position and distance between the bumper 10 and the anti-collision beam 20. It is only necessary to make the second connecting portion 323 fit and connect and fix with the bumper 10, and make the third connecting portion 324 fit and connect and fix with the anti-collision beam reinforcement plate 21, so as to realize the connection and fixation between the second auxiliary mounting bracket 32 ​​and the bumper 10 and the anti-collision beam 20 respectively, and make the second auxiliary mounting bracket 32 ​​be located on the rear lower side of the anti-collision beam 20.

[0050] Furthermore, a second reinforcing rib 325 can be provided on the third plate portion 321 and the fourth plate portion 322. The second reinforcing rib 325 is protrudingly provided and extends from the third plate portion 321 to the fourth plate portion 322, thereby improving the structural strength and rigidity of the second auxiliary mounting bracket 32, more stably and reliably suppressing the torsion of the bumper 10 in the left and right directions, and improving the vibration mode of the bumper 10.

[0051] Optionally, in some embodiments of the present invention, combined with Figure 3 and Figure 5 As shown, a third through hole 3231 may be provided on the second connection portion 323, and a fourth through hole may be provided on the bumper 10, and the third through hole 3231 corresponds to the fourth through hole and is connected and fixed by a fastener, thereby realizing the connection and fixation between the second connection portion 323 and the bumper 10. Also, a fifth through hole 3241 may be provided on the third connection portion 324, and a sixth through hole may be provided on the anti-collision beam reinforcement plate 21, and the fifth through hole 3241 corresponds to the sixth through hole and is connected and fixed by a fastener, thereby realizing the connection and fixation between the third connection portion 324 and the anti-collision beam reinforcement plate 21.

[0052] Of course, the connection and fixation between the second connection portion 323 and the bumper 10 , and the connection and fixation between the third connection portion 324 and the anti-collision beam reinforcement plate 21 , may also be other methods such as welding, which are not specifically limited here.

[0053] In this way, by optimizing the structures and installation positions of the first auxiliary mounting bracket 31 and the second auxiliary mounting bracket 32, it is possible to further ensure that a mutually pulling structural layout is formed between the bumper 10 and the anti-collision beam 20, so that a sufficient and reliable connection relationship is established between the bumper 10 and the anti-collision beam 20, thereby more stably and reliably suppressing the torsion of the bumper 10 in the left and right directions and improving the vibration mode of the bumper 10.

[0054] Combination Figure 1-Figure 3As shown, there are multiple first auxiliary mounting brackets 31, and the multiple first auxiliary mounting brackets 31 are arranged at intervals in the left-right direction. Specifically, by setting the number of first auxiliary mounting brackets 31 to be multiple, and arranging the multiple first auxiliary mounting brackets 31 at intervals in the left-right direction, the multiple first auxiliary mounting brackets 31 can be connected to the bumper 10 at different positions in the length direction of the anti-collision beam 20, which can not only increase the connection strength between the anti-collision beam 20 and the bumper 10, but also make the connection force evenly distributed in the left-right direction, thereby improving the connection stability and reliability between the anti-collision beam 20 and the bumper 10, avoiding the bumper 10 from twisting around the left-right direction, and meeting the vibration mode and fatigue requirements of the bumper 10.

[0055] Combination Figure 1-Figure 3 As shown, there are multiple second auxiliary mounting brackets 32, and the multiple second auxiliary mounting brackets 32 are arranged at intervals in the left-right direction. Specifically, by setting the second auxiliary mounting brackets 32 to be multiple, and arranging the multiple second auxiliary mounting brackets 32 at intervals in the left-right direction, the multiple second auxiliary mounting brackets 32 can be connected to the bumper 10 at different positions in the length direction of the anti-collision beam 20, which can not only increase the connection strength between the anti-collision beam 20 and the bumper 10, but also make the connection force evenly distributed in the left-right direction, thereby improving the connection stability and reliability between the anti-collision beam 20 and the bumper 10, avoiding the bumper 10 from twisting around the left-right direction, and meeting the vibration mode and fatigue requirements of the bumper 10.

[0056] In a specific embodiment of the present invention, there are four first auxiliary mounting brackets 31 and three second auxiliary mounting brackets 32 .

[0057] Combination Figure 1-Figure 3 as well as Figure 6 As shown, the vehicle 100 may further include: an energy absorption box 40 and a main mounting bracket 50, the energy absorption box 40 is connected to the rear of the anti-collision beam 20, the main mounting bracket 50 is at least partially arranged in front of the anti-collision beam 20, and the main mounting bracket 50 is connected between the bumper 10 and the energy absorption box 40.

[0058] Specifically, in order to meet the requirements of the safety collision of the anti-collision beam 20, the rigidity of the anti-collision beam 20 itself is designed to be relatively weak. By connecting the main mounting bracket 50 between the bumper 10 and the energy absorption box 40, one mounting point of the main mounting bracket 50 can be set on the energy absorption box 40 instead of on the anti-collision beam 20. Thus, without changing the size and structure of the anti-collision beam 20 to meet the safety collision, the installation stability of the bumper 10 is improved by optimizing the installation position of the main mounting bracket 50, and the mounting bracket between the anti-collision beam 20 and the bumper 10 is optimized and designed, so as to more stably and reliably suppress the torsion of the bumper 10 around the left and right directions and improve the vibration mode of the bumper 10. Among them, there are two energy absorption boxes 40 and two main mounting brackets 50, which correspond to each other.

[0059] Furthermore, combined with Figure 3 and Figure 6 As shown, an energy absorption box mounting bracket 41 is provided on the energy absorption box 40, and the main mounting bracket 50 may mainly include: a fifth plate portion 51, a sixth plate portion 52 and a seventh plate portion 53 which are connected in sequence, the sixth plate portion 52 is extended in the up and down directions, one end of the fifth plate portion 51 is connected to the upper end of the sixth plate portion 52, the other end of the fifth plate portion 51 is extended toward the rear, one end of the seventh plate portion 53 is connected to the lower end of the sixth plate portion 52, the other end of the seventh plate portion 53 is extended downward toward the rear, and the other end of the seventh plate portion 53 is connected to a fourth connecting portion 54 extending downward, the sixth plate portion 52 is fitted and fixedly connected to the bumper 10, the other end of the fifth plate portion 51 is fitted and fixedly connected to the energy absorption box mounting bracket 41, and the fourth connecting portion 54 is fitted and fixedly connected to the energy absorption box mounting bracket 41.

[0060] In this way, the fifth plate portion 51, the sixth plate portion 52, the seventh plate portion 53 and the fourth connecting portion 54 can form the overall structure of the main mounting bracket 50, so that the structure of the main mounting bracket 50 can conform to the positional relationship between the energy absorption box mounting bracket 41 and the bumper 10, which can not only facilitate the connection and fixation between the main mounting bracket 50 and the bumper 10 and the energy absorption box mounting bracket 41 respectively, but also enable the main mounting bracket 50 to avoid other components in the vehicle 100, thereby ensuring the normal operation of the main mounting bracket 50.

[0061] Specifically, the sixth plate portion 52 can be fitted with the bumper 10, and the sixth plate portion 52 can be connected and fixed to the bumper 10, thereby realizing the connection and fixation between the main mounting bracket 50 and the bumper 10, and the other end of the fifth plate portion 51 can be connected and fixed to the upper part of the energy absorption box mounting bracket 41, and the fourth connection portion 54 can be connected and fixed to the lower part of the energy absorption box mounting bracket 41, so that a triangular connection can be formed between the bumper 10 and the energy absorption box mounting bracket 41 through the main mounting bracket 50, which can improve the connection stability and reliability between the bumper 10 and the energy absorption box mounting bracket 41, thereby more stably and reliably suppressing the torsion of the bumper 10 around the left and right directions, and improving the vibration mode of the bumper 10.

[0062] Combination Figure 3 and Figure 6 As shown, the sixth plate portion 52 is also connected to a mounting portion 55 . There are two mounting portions 55 , which are respectively disposed on both sides of the sixth plate portion 52 in the left-right direction. The mounting portions 55 are fitted to and fixedly connected to the bumper 10 .

[0063] Specifically, by respectively arranging two mounting portions 55 on both sides of the sixth plate portion 52 in the left and right directions, the mounting portions 55 can also be used to connect and fix with the bumper 10, which not only increases the mounting points between the main mounting bracket 50 and the bumper 10, but also increases the contact area between the main mounting bracket 50 and the bumper 10, thereby optimizing the structure of the main mounting bracket 50, improving the connection strength between the main mounting bracket 50 and the bumper 10, ensuring the rigidity of the connection position between the main mounting bracket 50 and the bumper 10, and thereby more stably and reliably suppressing the torsion of the bumper 10 around the left and right directions, thereby improving the vibration mode of the bumper 10.

[0064] Optionally, in some embodiments of the present invention, combined with Figure 3 and Figure 6 As shown, a seventh through hole 56 may be provided on both the sixth plate portion 52 and the mounting portion 55, and an eighth through hole may be provided on the bumper 10.

[0065] Of course, the connection and fixation between the main mounting bracket 50 and the bumper 10, and the connection and fixation between the main mounting bracket 50 and the energy absorption box mounting bracket 41, can also be other methods such as welding, which are not specifically limited here.

[0066] Combination Figure 1-Figure 3 as well as Figure 7 , Figure 8 As shown, the vehicle 100 may further include: a frame 60 and a side mounting bracket 70, the frame 60 is located behind the anti-collision beam 20, the side mounting bracket 70 is extended in the left-right direction, there are two side mounting brackets 70 and they are spaced apart in the left-right direction, the side mounting bracket 70 includes: a first mounting plate 71 and a second mounting plate 72, the first mounting plate 71 and the second mounting plate 72 are both extended in the left-right direction, the first mounting plate 71 and the second mounting plate 72 are at least partially overlapped and connected and fixed, the first mounting plate 71 is connected to the bumper 10, and the second mounting plate 72 is connected to the frame 60.

[0067] Specifically, the frame 60 is located behind the anti-collision beam 20.

[0068] Furthermore, different from the prior art in which the side mounting bracket is set as a single plate, the present application makes the side mounting bracket 70 include a first mounting plate 71 and a second mounting plate 72, so that a first overlapping portion 711 can be set on the first mounting plate 71, and a second overlapping portion 721 can be set on the second mounting portion 55. The first overlapping portion 711 and the second overlapping portion 721 overlap each other and are connected and fixed. In this way, under the premise that the first mounting plate 71 is connected to the bumper 10 and the second mounting plate 72 is connected to the frame 60 to ensure the normal operation of the side mounting bracket 70, the first mounting plate 71 and the second mounting plate 72 are overlapped and connected, so as to improve the structural stiffness of the side mounting bracket 70 near the frame 60, thereby further suppressing the torsion of the bumper 10 around the front and rear directions and improving the vibration mode of the bumper 10.

[0069] Optionally, in some embodiments of the present invention, in combination with 7 and Figure 8 As shown, an eleventh through hole 712 can be provided on the first overlapping portion 711, and a twelfth through hole 722 can be provided on the second overlapping portion 721. The eleventh through hole 712 and the twelfth through hole 722 correspond to each other and are connected by fasteners, thereby realizing the connection and fixation between the first mounting plate 71 and the second mounting plate 72, so that the connection between the first mounting plate 71 and the second mounting plate 72 can be made simpler and more reliable, and the replacement of the first mounting plate 71 and the second mounting plate 72 can be facilitated. The fasteners include but are not limited to bolts.

[0070] Of course, the connection and fixation between the first mounting plate 71 and the second mounting plate 72 may also be by welding or other methods, which are not specifically limited here.

[0073] Combination Figure 7 As shown, the side mounting bracket 70 is provided with a first weight-reducing hole 73, and the circumferential edge of the first weight-reducing hole 73 is provided with a flange 731. Specifically, considering the split design of the side mounting bracket 70, the weight of the side mounting bracket 70 will increase compared with the prior art. By providing the first weight-reducing hole 73 on the side mounting bracket 70, the weight of the side mounting bracket 70 can be reduced, thereby achieving lightweighting of the side mounting bracket 70 and even the vehicle 100.

[0074] Furthermore, a flange 731 can be provided on the circumferential edge of the first weight reducing hole 73, and the flange 731 is provided in a protruding manner. This can reduce weight while improving the rigidity of the structure near the first weight reducing hole 73, thereby avoiding the loss of rigidity of the side mounting bracket 70 itself caused by the opening of the first weight reducing hole 73, and further improving the structural reliability of the side mounting bracket 70.

[0075] It should be noted that a second weight-reducing hole 3112 may be provided on the first auxiliary mounting bracket 31, a third weight-reducing hole 326 may be provided on the second auxiliary mounting bracket 32, and a fourth weight-reducing hole 58 may be provided on the main mounting bracket 50, thereby reducing the weight of the first auxiliary mounting bracket 31, the second auxiliary mounting bracket 32 ​​and the main mounting bracket 50, thereby achieving lightweighting of the vehicle 100, which will not be elaborated here.

[0076] Combination Figure 7As shown, the side mounting bracket 70 is provided with a third reinforcing rib 74. Specifically, by providing the third reinforcing rib 74 on the side mounting bracket 70, the third reinforcing rib 74 is protrudingly provided, so that the third reinforcing rib 74 can strengthen the structure of the side mounting bracket 70, thereby further improving the structural strength and structural rigidity of the side mounting bracket 70, and ensuring the connection stability and reliability between the bumper 10 and the frame 60.
