[0060] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present application are described in detail below.

[0061] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present application are described in detail below. Figures 1-7 The support assembly 200 according to the embodiments of the present application is described below.

[0062] Referring to FIG. 1, Figures 4-6 The support assembly 200 according to the first aspect of the present application includes:

[0063] The support body 100 is provided with an air guide structure 30 to realize the air guide function.

[0064] Specifically, in the prior art, an air guide structure is arranged on the front bumper to realize the air guide function. However, the front bumper is prone to interference with the air guide structure during installation, resulting in difficult installation. Moreover, there are problems of poor air guide effect and low air intake efficiency.

[0065] Therefore, the support assembly 200 needs to be optimized and designed. The support body 100 is provided with an air guide structure 30, that is, one air guide structure 30 can be arranged on the support body 100, or two air guide structures 30 and more than two air guide structures 30 can be arranged on the support body 100. In this way, at least one air guide structure 30 can play the role of air guide and can guide the airflow at the front end of the vehicle to the cooling module of the vehicle, thereby improving the cooling efficiency of the vehicle during driving.

[0066] Further, the support body 100 and the at least one air guide structure 30 together form an air inlet channel, which can increase the air inlet area and further increase the air inlet amount, thereby improving the air intake efficiency.

[0067] Therefore, the support body 100 is provided with at least one air guide structure 30, which can play the role of air guide and can guide the airflow at the front end of the vehicle to the cooling module of the vehicle, thereby improving the cooling efficiency of the vehicle during driving. In addition, the air inlet area can be increased, and the air inlet amount can be further increased, thereby improving the air intake efficiency.

[0068] According to some embodiments of the present application, as Figure 1 and Figure 6As shown, the air guide structure 30 has an air guide surface 33, which forms an angle a with the center axis of the vehicle width direction, and the air guide surface 33 gradually approaches the center axis of the vehicle width direction towards the rear end of the vehicle.

[0069] In this way, the air guide surface 33 can effectively guide the airflow and reduce air resistance. When the vehicle is running, the airflow in front can be more smoothly guided to the rear of the vehicle body through the air guide surface 33, which can reduce the generation of turbulence and vortex, thereby reducing air resistance, and can also guide the airflow at the front end of the vehicle to the cooling module of the vehicle.

[0070] According to some embodiments of the present application, the angle a satisfies the relationship: 61°≤a≤71°.

[0071] The optimal angle a of the air guide surface 33 and the center axis of the vehicle width direction can be set to 66°, so that not only the air inlet area can be increased, but also the formation of vortex can be effectively reduced, and the noise generated by airflow impact can be reduced, thereby improving the air inlet efficiency.

[0072] According to some embodiments of the present application, the support assembly (200) further comprises: a front end module, and the support body (100) is connected with the front end module. In this way, the support body (100) can provide support for the front end module, and the strength of the connection between the support body (100) and the front end module can be improved.

[0073] According to some embodiments of the present application, as shown in Figure 1 The support body 100 is arranged along the vehicle width direction, the air guide structure 30 is arranged on the upper two sides of the support body 100, and the air guide structure 30 is arranged inclined to the center axis of the vehicle width direction, so that the air guide function can be realized.

[0074] Specifically, the air guide structure 30 is arranged on the upper two sides of the support body 100, so that the air guide structure 30 on the upper two sides of the support body 100 and the support body 100 together form an air inlet channel, so that the air inlet area can be increased, the air inlet amount can be further increased, the air inlet efficiency can be improved, and the cooling efficiency of the vehicle during running can be improved.

[0075] Further, the air guide structure 30 is arranged inclined to the center axis of the vehicle width direction, that is, the lateral direction (left and right direction of the vehicle) of the vehicle, so that the angle of air inlet can be changed, and the airflow at the front end of the vehicle can be changed, thereby ensuring that the thermal management performance of the vehicle during normal running meets the standard.

[0076] Moreover, the air guide structure 30 is arranged on the support body 100, on the basis of improving the performance of pedestrian protection, air can be guided by the air guide structure 30 and the support body 100, so that the air inlet amount can be increased, and the purpose of combining pedestrian protection and vehicle thermal management performance can be achieved.

[0077] In addition, the air guide structure 30 is arranged obliquely relative to the center axis of the vehicle width direction, and the air guide structure 30 plays a role of guiding air, and can guide air to the cooling module of the vehicle, so that the air inlet amount at the cooling module can be increased, and the speed of the cooling module contacting air can be increased, so that the cooling efficiency can be improved.

[0078] According to some embodiments of the present application, as shown in Figure 1 The air guide structure 30 on both sides of the upper part of the support body 100 is symmetrically arranged relative to the center axis of the vehicle width direction.

[0079] Among them, the symmetrically arranged air guide structure 30 can ensure that the airflow is uniformly distributed on both sides, and can avoid the situation that one side airflow is too strong and the other side airflow is too weak, so that the vehicle can be uniformly cooled, and local overheating can be avoided. Moreover, the symmetrically arranged air guide structure 30 can also reduce the asymmetric stress caused by asymmetric airflow, so that the stability of the air guide structure 30 and the support body 100 as a whole can be improved.

[0080] According to some embodiments of the present application, as shown in Figure 1 The air guide structure 30 on both sides of the upper part of the support body 100 gradually approaches the rear of the vehicle.

[0081] Among them, the distance between the air guide structures 30 on both sides gradually decreases from the front end of the air guide structure 30 towards the vehicle to the rear end of the air guide structure 30 towards the vehicle, so that the air can be gathered, thereby preventing the diffusion of air.

[0082] According to some embodiments of the present application, as shown in Figure 1 The air guide structure 30 has an air guide surface 33, and the air guide surfaces (33) of the air guide structures (30) on both sides are arranged opposite to each other, and the shape formed by the intersection of the extension lines of the two air guide surfaces 33 is V-shaped.

[0083] Specifically, the V-shaped design can effectively guide the airflow to flow to the cooling module of the vehicle, and can better exchange heat, so that the cooling efficiency can be improved.

[0084] Moreover, the V-shaped design can reduce the turbulence phenomenon in the airflow, so that the noise generated by the vehicle during driving can be reduced.

Moreover, the plurality of first reinforcing ribs 32 are arranged in cross with each other, so that the support force can be provided to different directions of the air guide structure 30, and the strength of the air guide structure 30 in different directions can be improved, thereby the rigidity of the air guide body 31 can be ensured to be good in the normal driving state of the vehicle, and the air guide efficiency can be further ensured not to be affected.

[0087] According to some embodiments of the utility model, as shown in the drawings, Figure 1 The air guide structure 30 further comprises a first flange 34 connected to the bottom of the air guide body 31, and the first flange 34 is arranged in bending relative to the air guide body 31, and the air guide body 31 is arranged on the support body 100 through the first flange 34.

[0088] The first flange 34 is arranged, so that the contact area of the first flange 34 and the support body 100 can be increased, thereby the stress of the connecting position of the first flange 34 and the support body 100 can be reduced, and the connection of the first flange 34 and the support body 100 can be ensured to be more stable.

[0089] According to some embodiments of the utility model, as shown in the drawings, Figure 1 The first flange 34 is arranged with a mounting hole 341, and the first flange 34 is connected to the support body 100 through the mounting hole 341 by a fastener.

[0090] The fastener can be a bolt, the bolt can be fixedly connected with the support body 100 by penetrating the mounting hole 341 of the first flange 34, so that the connection of the first flange 34 and the support body 100 can be more stable and firm.

[0092] Specifically, the second flange 35 is arranged, so that the abutting area of the second flange 35 and the front end module can be increased, and the air guide structure 30 can abut against the front end module, thereby the air guide structure 30 can be more stable.

[0093] According to some embodiments of the utility model, the side of the support body 100 towards the rear of the vehicle is provided with a first mounting position 15, and the first mounting position 15 is used to mount the support body 100 and the bottom of the front end module.

[0094] The first mounting position 15 provides mounting space for the front end module, thereby reasonably utilizing the space and making the structure more compact.

[0102] In addition, the air guide structure mounting seats 193 are integrated with the support body 100, thereby ensuring that the air guide structure mounting seats 193 are more stably and firmly connected with the support body 100.

[0103] Further, the air guide structure 30 can be fixedly connected with the support body 100 through bolts, for example, two bolts are adopted, one of which is arranged through the first mounting hole 191, and the other is arranged through the second mounting hole 192, so that the fixed connection of the air guide structure 30 and the support body 100 can be realized.

[0104] In addition, the line connecting the first mounting hole 191 and the second mounting hole 192 forms an included angle α with the center axis in the vehicle width direction, by setting different included angles, different flow guide angles of the air guide structure 30 and the longitudinal center axis of the support body 100 can be formed, so that the vehicle front end airflow guide can be changed.

[0116] Specifically, the support body of the conventional front bumper is generally provided with an energy absorption part and a support part, the rigidity of the energy absorption part is small, and the energy absorption part can absorb the energy of the pedestrian collision by deformation when the pedestrian collides, but when subjected to other external impact, the energy absorption part is easy to tear and damage due to its small rigidity, and the energy absorption part also lacks support for the shins of the pedestrian, and there is a risk of knee ligament rupture when the pedestrian's legs collide.

[0117] Therefore, under the condition that the appearance of the small modified vehicle is not changed, the support body of the front bumper needs to be optimized, the support body 100 is mainly composed of a middle part 11, a side part 12 and an end part 13, and a plurality of second reinforcing ribs 20 are distributed at intervals in the middle part 11, the side part 12 and the end part 13, so as to provide support force for the middle part 11, the side part 12 and the end part 13, and increase the strength of the middle part 11, the side part 12 and the end part 13.

[0118] The average value b of the distance between the adjacent two second reinforcing ribs 20 in the side part 12 is greater than the average value a of the distance between the adjacent two second reinforcing ribs 20 in the middle part 11, that is, the rigidity of the side part 12 provided with the second reinforcing ribs 20 is relatively weak compared with the rigidity of the middle part 11 provided with the second reinforcing ribs 20, and when the pedestrian collides with the side part 12, the side part 12 can play a role of buffering and absorbing energy due to the relatively weak rigidity, so as to play a role of unloading the impact on the calf of the pedestrian, and also reduce the impact on the calf of the pedestrian.

[0119] Further, the side part 12 is connected to the two sides of the middle part 11, and when the side part 12 collides with the calf of the pedestrian, the rigidity of the middle part 11 is greater than the rigidity of the side part 12, so that the middle part 11 has high rigidity, and the impact energy is dispersed from the side part 12 to the middle part 11 instead of being concentrated in the side part 12, so as to reduce the stress concentration of the side part 12, avoid damage of the side part 12, and make the side part 12 play a supporting role on the calf of the pedestrian, thereby reducing the risk of fracture of the calf and rupture of the knee ligament of the pedestrian.

[0120] In addition, the average value b of the distance between the adjacent two second reinforcing ribs 20 in the side part 12 is greater than the average value c of the distance between the adjacent two second reinforcing ribs 20 in the end part 13, that is, the rigidity of the side part 12 provided with the second reinforcing ribs 20 is relatively weak compared with the rigidity of the end part 13 provided with the second reinforcing ribs 20, and when the pedestrian collides with the side part 12, the impact energy can be dispersed to the middle part 11 and the end part 13, and the impact force on the side part 12 can be further reduced, thereby avoiding damage of the side part 12. Since the rigidity of the side part 12 is relatively weak compared with the middle part 11 and the end part 13, the stress on the calf of the pedestrian can be buffered, thereby protecting the calf of the pedestrian, preventing damage of the middle part 11 and the end part 13, and reducing the cost of the support body 100 of the front bumper.

[0121] Further, the support body 100 has a variable rigidity structure as a whole, one part has relatively high support rigidity, and the other part has relatively low rigidity, so as to absorb the impact energy. In this way, the calf rebound can be advanced on the basis of appropriately increasing the support of the calf of the pedestrian, so as to reduce the extension of the medial ligament of the knee of the pedestrian and reduce the risk of rupture of the knee ligament of the pedestrian.

[0122] Specifically, the middle part 11 has high rigidity, which can reduce the vibration amplitude of the side part 12 under impact, thereby improving the stability of the whole, and can also change the natural frequency of the support body 100, reduce resonance, and reduce resonance, which can further improve the durability of the support body 100.

[0123] Therefore, the support body 100 of the front bumper has a variable rigidity structure, which can reduce the impact on the shank of the pedestrian, and can support the shank of the pedestrian, thereby reducing the risk of fracture of the shank and rupture of the knee ligament of the pedestrian, and can also change the natural frequency of the support body 100 and reduce resonance.

[0124] According to some embodiments of the present application, as shown in Figure 5 a satisfies the relationship: 10mm≤a≤25mm, and / or b satisfies the relationship: 30mm≤b≤45mm, and / or c satisfies the relationship: 10mm≤c≤25mm.

[0125] The average value a of the distance between the adjacent two second reinforcing ribs 20 in the middle part 11 is at least 10mm, and the average value b of the distance between the adjacent two second reinforcing ribs 20 in the side part 12 is at least 30mm. If the average value b of the distance between the adjacent two second reinforcing ribs 20 in the side part 12 is less than 30mm, the rigidity of the side part 12 will be larger, and when the shank of the pedestrian hits the side part 12, it cannot be buffered and absorbed, resulting in fracture of the shank of the pedestrian. When the middle part 11 and the side part 12 are of the same size, the number of second reinforcing ribs 20 in the middle part 11 is greater than that in the side part 12, so that the support rigidity of the middle part 11 is greater than that of the side part 12.

[0126] Further, the average value a of the distance between the adjacent two second reinforcing ribs 20 in the middle part 11 is at most 25mm, and the average value b of the distance between the adjacent two second reinforcing ribs 20 in the side part 12 is at most 45mm. The maximum value of a is less than the maximum value of b, that is, the density of the second reinforcing ribs 20 arranged in the middle part 11 is greater than that in the side part 12, so that the support rigidity of the middle part 11 can always be greater than that of the side part 12.

[0127] Similarly, the average distance between two adjacent second reinforcing ribs 20 in the end portion 13 is at least 10mm, and the average distance b between two adjacent second reinforcing ribs 20 in the side portion 12 is at least 30mm. If the average distance b between two adjacent second reinforcing ribs 20 in the side portion 12 is less than 30mm, the rigidity of the side portion 12 will be too large, and the calf of the pedestrian will not be able to be absorbed when it hits the side portion 12, resulting in a fracture of the calf of the pedestrian. When the end portion 13 and the side portion 12 have the same size, the number of second reinforcing ribs 20 in the end portion 13 is greater than that in the side portion 12. In this way, the support rigidity of the end portion 13 is greater than that of the side portion 12, which can improve the strength of the connection between the end portion 13 and other structures, thereby preventing the end portion 13 from falling off during the impact.

[0128] Further, the average distance c between two adjacent second reinforcing ribs 20 in the end portion 13 is at most 25mm, and the average distance b between two adjacent second reinforcing ribs 20 in the side portion 12 is at most 45mm. The maximum value of c is less than that of b, so that the support rigidity of the side portion 12 is always less than that of the end portion 13.

[0129] According to the specific embodiments of the utility model, referring to Figures 4-6 the maximum distance between two adjacent second reinforcing ribs 20 in the middle portion 11 and the maximum distance between two adjacent second reinforcing ribs 20 in the end portion 13 are both less than the minimum distance between two adjacent second reinforcing ribs 20 in the side portion 12.

[0130] Specifically, the rigidity of the middle portion 11 of the support body 100 is relatively large compared to that of the side portion 12 and the end portion 13, and the rigidity of the end portion 13 is relatively small compared to that of the side portion 12. In this way, the rigidity of the support body 100 from the middle portion 11 to the end portion 13 is distributed in a strong-weak-strong manner. In this way, the support body 100 can be optimized. The relatively strong rigidity of the middle portion 11 and the end portion 13 can resist deformation under external force, and can effectively maintain the overall stability and shape invariance of the support body 100 when subjected to lateral force or torque. The relatively weak rigidity of the side portion 12 can provide a certain flexibility, which can disperse stress concentration, thereby avoiding damage caused by local overload.

[0131] According to some embodiments of the utility model, referring to Figures 4-6 the distance between two adjacent second reinforcing ribs 20 in the side portion 12 is the same, or the distance between two adjacent second reinforcing ribs 20 located at the center of the side portion 12 is less than that between two adjacent second reinforcing ribs 20 located at the two ends of the side portion 12.

[0132] The plurality of second reinforcing ribs 20 in the side portion 12 are evenly spaced, so that the force distribution of the side portion 12 is more uniform, thereby preventing stress concentration of the side portion 12.

[0133] Alternatively, the distance between the two adjacent second reinforcing ribs 20 in the center of the side portion 12 is less than the distance between the two adjacent second reinforcing ribs 20 at the two ends of the side portion 12, that is, the side portion 12 can be further optimized, and the rigidity of the side portion 12 as a whole is distributed as weak-strong-weak in the transverse direction, so that the rigidity of the support body 100 changes in the transverse space, thereby reducing the risk of fracture of the tibia and rupture of the knee ligament of the lower leg of the pedestrian.

[0134] Specifically, the plurality of second reinforcing ribs 20 at the center of the side portion 12 are densely distributed, and the plurality of second reinforcing ribs 20 at the two ends of the side portion 12 are sparsely distributed relative to the plurality of second reinforcing ribs 20 at the center of the side portion 12, so that the rigidity of the center of the side portion 12 is greater than the rigidity of the two ends of the side portion 12, thereby further avoiding damage to the center of the side portion 12.

[0135] According to some embodiments of the present application, referring to Figures 4-6 , the distance between the two adjacent second reinforcing ribs 20 in the middle portion 11 is the same, and / or the distance between the two adjacent second reinforcing ribs 20 in the end portion 13 is the same.

[0136] The plurality of reinforcing ribs in the middle portion 11 are evenly spaced, so that the force on the middle portion 11 is more uniform, and the plurality of reinforcing ribs in the end portion 13 are evenly spaced, so that the force on the end portion 13 is more uniform.

[0137] According to some embodiments of the present application, referring to Figures 4-6 , the plurality of second reinforcing ribs 20 extend in the front-rear direction of the vehicle along the support body 100, and the plurality of second reinforcing ribs 20 are spaced apart in the length direction of the support body 100, and / or the plurality of second reinforcing ribs 20 are arranged on the bottom of the support body 100, and / or the upper portion of the support body 100 is formed with a smooth surface.

[0138] The plurality of second reinforcing ribs 20 extend in the front-rear direction of the vehicle along the support body 100, so that the rigidity of the support body 100 in the front-rear direction of the vehicle is increased, preventing the support body 100 from deforming in the front-rear direction of the vehicle. Moreover, the plurality of second reinforcing ribs 20 are spaced apart in the length direction of the support body 100, so that the rigidity of the support body 100 in the length direction is also improved.

[0139] Further, the plurality of second reinforcing ribs 20 are arranged at the bottom of the support body 100, i.e. the back of the support body 100 (the lower surface of the support body 100), so that the upper part of the support body 100 can form a smooth surface, thereby reducing the damping in the air inlet channel and ensuring smooth air intake.

[0140] In addition, the plurality of second reinforcing ribs 20 arranged at the bottom of the support body 100 can prevent the accumulation of foreign matter, water and oil in the grooves of the second reinforcing ribs 20, thereby preventing abnormal noise and stress concentration.

[0141] According to some embodiments of the present application, as shown in Figure 2 The cross-sectional shape of the support body 100 in the vehicle front-rear direction is V-shaped with the opening facing the rear of the vehicle.

[0142] The upper surface of the support body 100 and the lower surface of the support body 100 together form a V shape, thereby further reducing the damping in the air inlet channel and ensuring smooth air intake.

[0143] According to some embodiments of the present application, as shown in Figure 6 The size of the middle portion 11 in the lateral direction is d, which satisfies the relationship 200mm≤d≤230mm, and / or the size of the side portion 12 in the lateral direction is e, which satisfies the relationship 160mm≤e≤190mm, and / or the size of the end portion 13 in the lateral direction is f, which satisfies the relationship 260mm≤f≤300mm.

[0144] The size of the middle portion 11 in the lateral direction is in the range of 200mm to 230mm, the size of the side portion 12 in the lateral direction is in the range of 160mm to 190mm, and the size of the middle portion 11 in the lateral direction is greater than the size of the side portion 12 in the lateral direction, so that the middle portion 11 of the support body 100 has sufficient rigidity. Similarly, the size of the end portion 13 in the lateral direction is greater than the size of the side portion 12 in the lateral direction, and the size of the end portion 13 in the lateral direction is also greater than the size of the middle portion 11 in the lateral direction, so that the end portion 13 has sufficient rigidity, and the rigidity of the end portion 13 is greater than the rigidity of the side portion 12, and the rigidity of the end portion 13 is greater than the rigidity of the middle portion 11, thereby preventing the end portion 13 from falling during impact.

[0145] According to some embodiments of the present application, as shown in Figure 4As shown, the edges of the support body 100 include a front edge 16, a rear edge 17 and side edges 18 connected to the transverse sides of the front edge 16 and the rear edge 17, the side edges 18 are arranged in a bent manner relative to the front edge 16, and the side edges 18 are located outside the corresponding end portions 13, at least part of the side edges 18 are located inside the rearwardly extending extension line of the front edge 16, and / or the support body 100 is arranged symmetrically about the longitudinal center axis thereof.

[0146] The front edge 16 faces the front of the vehicle, the rear edge 17 faces the rear of the vehicle, the side edges 18 are arranged in a bent manner relative to the front edge 16, and at least part of the side edges 18 are located inside the rearwardly extending extension line of the front edge 16, so that the side edges 18 located outside the end portions 13 have a smaller curvature, for example, the curvature range of the side edges 18 can be set to 0.023 (rad / mm) to 0.036 (rad / mm), so that the support body 100 can better fit the internal gap of the lower skin of the front bumper, thereby improving the support of the vehicle to the lower leg of the pedestrian.

[0147] In addition, the support body 100 is arranged symmetrically about the center axis in the vehicle width direction, so that the stress balance of the support body 100 on both sides of the center axis in the vehicle width direction can be achieved, thereby avoiding deformation of the support body 100 due to uneven stress.

[0148] In addition, the support body 100 can cover the specified pedestrian protection leg impact test area, and provide full-range support for the lower leg of the pedestrian, thereby further reducing the risk of the lower leg of the pedestrian being involved in the vehicle bottom.

[0149] According to some embodiments of the present application, at least one of the support body 100 and the air guide body 31 is a plastic part.

[0150] The support body 100 can be arranged as a plastic part, or the air guide body 31 can be arranged as a plastic part, so that compared with a sheet metal structure having the same function, lightweight design can be achieved, thereby reducing the weight of the vehicle.

[0151] According to the air guide system of the second aspect of the present application, the support assembly 200 of the front bumper of the above embodiment is provided, wherein the support body 100 is arranged between the front bumper and the front end module, thereby increasing the support of the lower part of the vehicle front bumper to the lower leg of the pedestrian.

[0152] Further, the support body 100 matches the rigidity of the skin of the vehicle front bumper, and thus the support property of the vehicle front end to the shank of a pedestrian can be improved at the time of collision, and the shape of the support body 100 and the air guide structure 30 can be changed according to the actual situation. Further, the weight reduction can be achieved by reducing the thickness of the material, reducing the strength of the material, and reducing the weight of the support body 100 and the air guide structure 30.
