[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0040] According to the first aspect of this application, see Figure 1The radiator assembly mounting structure 1 provided in the present invention is used for a vehicle, and includes a subframe 2 and a radiator assembly 3, wherein the radiator assembly 3 is rotatably mounted on the subframe 2; when the vehicle is hit, the radiator assembly 3 rotates relative to the subframe 2 to move away from the impact point of the vehicle.
[0041] Among them, the radiator assembly includes the fan assembly, intercooler, and condenser integration.
[0042] In this embodiment, the radiator assembly 3 is rotatably connected to the subframe 2. When impacted, the radiator assembly 3 rotates to move away from the impact point to prevent the radiator assembly 3 from being squeezed and damaged, thereby alleviating the technical problem in the prior art that the radiator assembly 3 of the radiator assembly mounting structure 1 is easily damaged when impacted.
[0043] In one embodiment, see Figure 1 and Figure 2 The radiator assembly 3 extends in the width direction of the vehicle relative to the rotation axis of the subframe 2.
[0044] The radiator assembly 3 rotates around a rotation axis, and the rotation axis extends along a first direction, which is a width direction of the vehicle.
[0045] The radiator assembly 3 is rotatably connected to the sub-frame 2 and rotates relative to the sub-frame 2 during an impact.
[0046] It can be understood that when a head-on collision occurs, the force direction of the radiator assembly 3 is roughly toward the length direction of the vehicle, so that the rotation axis of the subframe 2 extends along the width direction of the vehicle, which facilitates the radiator assembly 3 to rotate around the rotation axis when hit and deflect in the second direction (i.e., the height direction of the vehicle) to avoid and stay away from the impact point, thereby preventing the radiator assembly 3 from being squeezed and damaged.
[0047] It is understandable that when a side impact occurs, the rotation axis of the radiator assembly 3 is along the length direction of the vehicle and deflected along the second direction (i.e., the height direction of the vehicle) to avoid and move away from the impact point, preventing the radiator assembly 3 from being squeezed and damaged.
[0048] In one embodiment, see Figure 2 The radiator assembly 3 is rotatably connected to the subframe 2 at the rear mounting point 5 through a pin 9.
[0049] The radiator assembly 3 and the subframe 2 are both provided with shaft holes, and the pin shaft 9 passes through the shaft holes of the radiator assembly 3 and the subframe 2. A gasket can also be arranged between the radiator assembly 3 and the subframe 2, and the gasket is provided with a perforation for the pin shaft 9 to pass through.
[0050] It can be understood that the radiator assembly 3 and the subframe 2 are connected by the pin shaft 9 at the rear mounting point 5, which facilitates the rotational connection between the radiator assembly 3 and the subframe 2 and improves the rotational stability of the radiator assembly 3. By arranging a gasket between the radiator assembly 3 and the subframe 2, the rotational stability of the radiator assembly 3 can be further improved.
[0051] In one embodiment, see Figure 3 and Figure 4 , further comprising a first bracket 6 (ie, the first bracket) and a second bracket 4 (ie, the second bracket), the radiator assembly 3 being mounted on the first bracket 6 via the second bracket 4; wherein, when the vehicle is hit, the second bracket 4 is broken.
[0052] The first bracket 6 is directly or indirectly connected to the anti-collision beam assembly 7. For example, the first bracket 6 can be fixed to the anti-collision beam assembly 7 by bolts or the like.
[0053] The radiator assembly 3 includes a second bracket 4 , and the second bracket 4 is integrally formed and arranged at one end of the radiator assembly 3 close to the first bracket 6 .
[0054] It is understandable that the first bracket 6 is fixedly connected to the second bracket 4, the second bracket 4 is broken by the collision, and the radiator assembly 3 rotates relative to the subframe 2 toward the side away from the collision point, thereby preventing the radiator assembly 3 from being squeezed and damaged during the collision. For example, the first bracket 6 can be fixed to the second bracket 4 by means of a buckle, specifically, the first bracket 6 is provided with a protrusion to be inserted into the clamping hole of the second bracket 4. The first bracket 6 can also be fixed to the second bracket 4 by means of bolts.
[0055] In one embodiment, see Figure 3 The second bracket 4 includes a bracket body 41 (ie, the bracket body), and the bracket body 41 is provided with a weakened portion 42. When the vehicle is hit, the weakened portion 42 breaks.
[0056] The weakened portion 42 will break before the bracket body 41 during impact.
[0057] It can be understood that the weakened portion 42 is easier to break than the bracket body 41 during a collision, so that the second bracket 4 is easy to break at the weakened portion 42 during a collision. Under low-speed impact conditions, the formation of the weakened portion 42 can facilitate the breakage of the second bracket 4, allowing the radiator assembly 3 to detach from the first bracket 6 and move away from the impact point.
[0058] In one embodiment, the strength of the weakened portion 42 is less than the strength of the bracket body 41 .
[0059] It can be understood that the strength of the weakened portion 42 is less than the strength of the bracket body 41 , so that the weakened portion 42 is more likely to break.
[0060] In one embodiment, the ratio of the strength of the weakened portion 42 to the strength of the bracket body 41 is in a range of 0.7 to 0.8.
[0061] The ratio of the strength of the weakened portion 42 to the strength of the bracket body 41 may be any one of 0.7, 0.75, and 0.8.
[0062] It is understandable that the ratio of the strength of the weakened portion 42 to the strength of the bracket body 41 is less than 0.7, which makes the stiffness of the weakened portion 42 too low. When the vehicle encounters a bumpy road, the weakened portion 42 will break abnormally and the durability of the weakened portion 42 is poor.
[0063] It can be understood that the ratio of the strength of the weakened portion 42 to the strength of the bracket body 41 is greater than 0.8, so that the strength of the weakened portion 42 is close to that of the bracket body 41, and the second bracket 4 is not easy to break, or the breaking position is unclear, so that the radiator assembly 3 cannot move away from the impact point in time when a collision occurs.
[0064] In one embodiment, the cross-sectional area of the weakened portion 42 is smaller than the cross-sectional area of the bracket body 41 .
[0065] It can be understood that making the cross-sectional area of the weakened portion 42 smaller than the cross-sectional area of the bracket body 41 facilitates the weakened portion 42 to break under impact.
[0066] In one embodiment, the elongation of the weakened portion 42 is lower than the elongation of the bracket body 41 .
[0067] The weakened portion 42 and the bracket body 41 may be integrally formed.
[0068] The weakened portion 42 and the bracket body 41 may be made of the same material.
[0069] The material grade of the weakened portion 42 and the bracket body 41 is PA66.
[0070] It is understandable that by preparing the second bracket 4 by injection molding, the different elongation rates of the weakened portion 42 and the bracket body 41 can be achieved through the process.
[0071] It can be understood that by making the elongation of the material of the weakened portion 42 lower, the weakened portion 42 is made easier to break than the bracket body 41 .
[0072] In one embodiment, the thickness of the bracket body 41 is greater than the thickness of the weakened portion 42 .
[0073] It is understandable that, compared with the bracket body 41, by reducing the thickness of the weakened portion 42, the weakened portion 42 is more likely to break under impact, thereby causing the radiator assembly 3 to rotate toward the side away from the impact point, thereby preventing the radiator assembly 3 from being squeezed and damaged.
[0074] In one embodiment, the thickness of the weakened portion 42 is d, wherein 1 mm ≤ d < 1.5 mm.
[0075] The thickness of the weakened portion 42 may be any one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, and 1.4 mm.
[0076] It can be understood that the thickness of the bracket body 41 can be 1.5 mm, and the thickness of the weakened portion 42 needs to be smaller than the thickness of the bracket body 41. At the same time, the thickness of the weakened portion 42 cannot be less than 1 mm. When the thickness of the weakened portion 42 is less than 1 mm, the stiffness of the weakened portion 42 will be too low and the durability will be poor. When the car encounters a bumpy road, the weakened portion 42 will break abnormally.
[0077] In one embodiment, the critical fracture force of the weakened portion 42 ranges from 1000 Newtons to 1200 Newtons.
[0078] The critical fracture force refers to the critical value of the reaction force exerted on the weakened portion 42 during impact. When the reaction force is greater than or equal to the critical fracture force, the weakened portion 42 will fracture.
[0079] The critical breaking force of the weakened portion 42 may be any one of 1000 N, 1100 N, and 1200 N.
[0080] It can be understood that when an impact occurs, when the reaction force exerted on the weakened portion 42 is greater than or equal to the critical fracture force, the weakened portion 42 will fracture. The critical fracture force of the weakened portion 42 ranges from 1000 N to 1200 N. When the critical fracture force is lower than 1000 N, the weakened portion 42 may easily fracture abnormally on a bumpy road surface. When the critical fracture force is higher than 1200 N, the weakened portion 42 may not easily fracture, making the radiator assembly 3 easily squeezed and damaged during a low-speed impact.
[0081] In one embodiment, see Figure 3 A notch 8 is provided on the outer side of the weakened portion 42 .
[0082] The notch 8 and the weakened portion 42 are arranged opposite to each other.
[0083] It can be understood that, through the design of the notch 8 , the weakened portion 42 is easier to break than the bracket body 41 .
[0084] In one embodiment, the ratio of the depth of the notch 8 to the width of the bracket body 41 along the depth direction ranges from 1 / 8 to 1 / 6.
[0085] The ratio of the depth of the notch 8 to the width of the bracket body 41 along the depth direction may be any one of 1 / 8, 1 / 7, and 1 / 6.
[0086] It can be understood that when the ratio of the depth of the notch 8 to the width of the bracket body 41 along the depth direction is greater than 1 / 6, the stiffness of the weakened portion 42 is too low, the vehicle is prone to abnormal fracture when encountering a bumpy road surface, and the weakened portion 42 has poor durability; when the ratio of the depth of the notch 8 to the width of the bracket body 41 along the depth direction is less than 1 / 8, the second bracket 4 is not easy to break, or the fracture position is unclear, so that the radiator assembly 3 cannot move away from the impact point in time during an impact.
[0087] In this embodiment, the notch 8 is provided to form the weakened portion 42, so that the weakened portion 42 breaks when impacted, so that the radiator assembly 3 rotates toward the side away from the impact point when impacted, so as to avoid heat dissipation damage when impacted.
[0088] In one embodiment, see Figure 3 The second bracket 4 includes two notches 8 , and the two notches 8 are symmetrically arranged on two opposite sides of the weakened portion 42 .
[0089] It can be understood that the notches 8 are relatively and symmetrically arranged, which not only simplifies the manufacturing process, but also facilitates the weakened portion 42 to break when impacted.
[0090] In one embodiment, see Figure 1 , and also includes an anti-collision beam assembly 7, which is fixedly connected to the other end of the first bracket 6.
[0091] Among them, the anti-collision beam assembly 7 includes an anti-collision beam and an energy absorption box. The rear anti-collision beam extends along the width direction of the vehicle. The left and right ends of the rear anti-collision beam are connected to the energy absorption box. One end of the energy absorption box is connected to the subframe 2, and the other end of the energy absorption box is connected to the anti-collision beam.
[0092] Among them, the energy absorption box can include two U-shaped parts, the openings of the two U-shaped parts are arranged oppositely, the two U-shaped parts are symmetrically buckled up and down or symmetrically left and right, and are connected by welding. During welding, a shielding gas shielding welding method can be adopted, and the shielding gas can be carbon dioxide.
[0093] The two U-shaped parts can be connected by screws after being buckled symmetrically up and down or left and right.
[0094] Among them, reinforcing ribs may be arranged in the energy absorbing box, and the reinforcing ribs are arranged along the length direction of the energy absorbing box to improve the anti-deformation performance of the energy absorbing box.
[0095] Among them, multiple reinforcing ribs can be provided, and the multiple reinforcing ribs are arranged at equal intervals to improve the uniformity of the deformation resistance of the energy absorption box.
[0096] The structure of the reinforcing ribs may be a cavity-type rib structure or a sheet-like structure.
[0097] It is understandable that when the anti-collision beam is hit, the anti-collision beam will compress the energy absorbing box. After the energy absorbing box is crushed, it will drive the first bracket 6 and the second bracket 4 to break the second bracket 4.
[0098] The anti-collision beam assembly 7 and the other end of the first bracket 6 can be fixedly connected by bolts to make the connection more secure.
[0099] It can be understood that the anti-collision beam assembly 7 is fixedly connected to the first bracket 6, which is conducive to transmitting the impact force exerted on the anti-collision beam assembly 7 to the second bracket 4 through the first bracket 6, so that the impact force can be better transmitted to the second bracket 4, so as to cause the second bracket 4 to break.
[0100] In this embodiment, when a frontal collision occurs on the vehicle, the anti-collision beam assembly 7 can cause the entire vehicle to shift toward the side away from the collision object, avoiding or moving as far away from the collision object as possible, thereby reducing the degree of collision damage to the vehicle body and ensuring the personal safety of the front-seat passengers.
[0101] In one embodiment, see Figure 1 When the vehicle is in a normal state, the radiator assembly 3 is tilted relative to the plane where the length direction and the width direction of the subframe 2 are located. The normal state refers to a state without impact, such as a normal driving state or a normal parking state.
[0102] It can be understood that the tilted setting of the radiator assembly 3 can improve the heat dissipation capacity, increase the space utilization, and help reduce wind resistance.
[0103] In one embodiment, the angle between the radiator assembly 3 and the plane ranges from 40 degrees to 90 degrees.
[0104] The angle between the radiator assembly 3 and the plane may be any one of 40 degrees, 50 degrees, 60 degrees, 70 degrees, and 80 degrees.
[0105] It is understandable that when the angle between the radiator assembly 3 and the plane is less than 40°, the radiator assembly 3 is not easy to flip over to avoid the collision, and the radiator assembly 3 is more likely to be squeezed and damaged during the collision.
[0106] In this embodiment, the angle between the radiator assembly 3 and the plane is in the range of 40 degrees to 90 degrees, which is conducive to the radiator assembly 3 turning over and avoiding.
[0107] In one embodiment, the second bracket 4 includes at least one weakened portion 42 , and the weakened portion 42 is provided with a hole or a groove.
[0108] The depth of the groove accounts for 1 / 8 to 1 / 6 of the width of the bracket body 41 along the depth direction.
[0109] The depth of the groove may account for any one of 1 / 8, 1 / 7 and 1 / 6 of the width of the bracket body 41 along the depth direction.
[0110] It can be understood that by providing a hole or a groove in the weakened portion 42 , during a collision, the second bracket 4 is easily broken at the position where the hole or the groove is provided in the weakened portion 42 .
[0111] In one embodiment, see Figure 1 , Figure 4 , Figure 5 The radiator assembly 3 includes two second brackets 4 and two rear mounting points 5, wherein if any second bracket 4 breaks, the radiator assembly 3 drives the other second bracket 4 to break.
[0112] The two second brackets 4 may be symmetrically arranged so that the second brackets 4 can be broken when impacted.
[0113] The two rear mounting points 5 may also be symmetrically arranged, which is conducive to the radiator assembly 3 stably rotating around the rear mounting point 5 toward the side away from the impact point.
[0114] It can be understood that, taking a frontal collision at a speed of 10 km / h as an example, in a frontal collision at a speed of 10 km / h, both second brackets 4 break upon impact, and the radiator assembly 3 rotates around the rear mounting point 5 toward the side away from the impact point to complete the radiator assembly 3's avoidance of the impact.
[0115] It can be understood that, taking a single-sided side collision with a speed of 16 km / h and an overlap rate of 40% as an example, under the single-sided side collision test, any one of the two second brackets 4 breaks, causing the radiator assembly 3 to shift on the side of the broken second bracket 4, prompting the radiator assembly 3 to drive the other second bracket 4 to break, so as to achieve passive avoidance of the radiator assembly 3 when impacted.
[0116] The present application realizes that the rear mounting point 5 of the radiator assembly 3 is rotatably connected to the subframe 2, and the second bracket 4 breaks when impacted, and the radiator assembly 3 rotates around the rear mounting point 5, so as to achieve the radiator assembly 3 avoiding the impact point, prevent the radiator assembly 3 from being squeezed and causing leakage, reduce the degree of damage to the radiator assembly 3, reduce maintenance costs, and improve maintainability and maintenance economy.
[0117] In one embodiment, an anti-collision beam assembly 7 is further included. When the vehicle is hit, the radiator assembly 3 rotates toward a side away from the anti-collision beam assembly 7 .
[0118] In one embodiment, the radiator assembly 3 extends along the length direction of the vehicle relative to the rotation axis of the subframe 2 .
[0119] According to a second aspect of the present disclosure, a vehicle is provided, the vehicle comprising the radiator assembly mounting structure 1 of any of the above-mentioned embodiments, the vehicle having all the beneficial effects of the radiator assembly mounting structure 1 of any of the embodiments, which will not be described in detail in the present disclosure.
[0120] The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and the present disclosure does not make any specific limitation on this.
[0121] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

[0122] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0123] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.
[0124] The above are only preferred embodiments of the present application and do not constitute any form of limitation to the present application. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
