Technical Field

[0001] The present application relates to the automotive field, and in particular to a front-end module and a vehicle. Background Art

[0002] In the related art, the radiator of the vehicle needs to be fixed in the front cabin by means of a mounting bracket. The mounting bracket of the current automobiles on the market is set as an integrated device, and the mounting bracket runs through the lower end of the entire radiator. The size is large, so that it occupies more space in the front cabin, and the space utilization rate of the front cabin is low. In addition, the mounting bracket is set as an integrated device, and the repair cost is high when the vehicle collides later. Utility Model Content

[0003] The purpose of the present application is to provide a front-end module and a vehicle, wherein the front-end module occupies a small space and has a low maintenance cost.

[0004] The first aspect of the present application provides a front-end module, comprising a first bracket, a second bracket and a radiator assembly. The first bracket and the second bracket are separately arranged, and along the height direction of the front-end module, the first bracket and the second bracket are arranged at intervals, and the radiator assembly is located between the first bracket and the second bracket.

[0005] The first bracket is used to fix the upper end of the radiator assembly to the vehicle frame. The second bracket includes two sub-brackets, which are separately arranged and spaced apart along the width direction of the front-end module. The two sub-brackets are used to fix the lower end of the radiator assembly to the vehicle frame.

[0006] The front-end module provided in this embodiment is applied to a vehicle, and the second bracket is divided into two sub-brackets, and the two sub-brackets are arranged on both sides of the radiator assembly along the width direction, and the lower end of the radiator assembly is fixed by the two sub-brackets. Compared with the related art that uses an integrated bracket that runs through the entire bottom of the radiator to fix the lower end of the radiator, the two sub-brackets are smaller in size and occupy less space in the front cabin, so that the space utilization rate of the front cabin is higher, which is convenient for the layout of other structures and pipelines in the front cabin.

[0007] In addition, the two sub-brackets are separately arranged, so if the vehicle collides, local repairs can be performed at a lower cost.

[0008] In some embodiments, the first bracket includes a main body, a first leg and a second leg, and the upper end of the radiator assembly is fixed to the frame through the main body. One end of the first leg and the second leg are connected to the side of the main body facing the second bracket, and the first leg and the second leg are arranged at an angle. One end of the first leg away from the main body is connected to the frame, and one end of the second leg away from the main body is connected to the frame.

[0009] By setting the first leg and the second leg, the first leg and the second leg are set at an angle, one end of the first leg and the second leg is connected to the main body, and the other ends of the first leg and the second leg are supported on the frame. The main body obtains two supporting forces through the first leg and the second leg, and the stability of the main body is higher, so that the radiator assembly can be fixed more firmly. In addition, the first leg and the second leg are set at an angle, and the structural strength is higher.

[0010] In some embodiments, the main body is provided with two first mounting parts, the two first mounting parts are located on the side of the main body facing the second bracket, and the two first mounting parts are arranged at intervals. The first mounting part includes a first mounting surface, and the first mounting surface is concavely provided with a positioning groove. The radiator assembly is provided with positioning protrusions at both ends along the width direction, and when the upper end of the radiator assembly is fixed to the first mounting part, the positioning protrusion is snapped into the positioning groove.

[0011] When fixing the radiator assembly to the main body, first insert the positioning protrusion into the positioning groove, and then use bolts to fix the radiator assembly to the main body. By providing the positioning protrusion and the positioning groove, it is convenient for operators to position, making the assembly speed faster and thus improving production efficiency. In addition, the outer side of the positioning protrusion abuts against the side of the positioning groove, which can prevent the main body and the radiator assembly from shaking severely and prevent the bolts from loosening.

[0012] In some embodiments, the first support leg and the second support leg are located between the two first mounting portions, and one end of the first support leg and the second support leg are connected to the middle portion of the body along the width direction.

[0013] It can be understood that one end of the first support leg and the second support leg are connected to the middle part of the main body along the width direction, so that the supporting force mainly acts on the middle part of the main body, and the stability of the main body is higher.

[0014] In some embodiments, the sub-bracket includes a mounting member and a connecting member, and the mounting member and the connecting member are fixedly connected. The connecting member is fixed to the vehicle frame, and the radiator assembly is fixed to two mounting members on both sides along the width direction of the front end module.

[0015] The mounting parts and the connecting parts are formed by sheet metal processing, and the mounting parts and the connecting parts are fixed by welding to form a sub-bracket. That is, the sub-bracket is processed separately, the structure is simple, and the processing cost is low. In addition, after the sub-bracket is processed, it can be directly fixed on the frame. That is, the sub-bracket is set as one piece with the frame, and when the radiator assembly is installed later, the radiator assembly can be fixed to the mounting parts, which reduces the installation process.

[0016] In some embodiments, the mounting member includes a fixing plate, the fixing plate includes a first surface and a second surface disposed opposite to each other. The fixing plate is provided with a mounting hole penetrating the first surface and the second surface, and the heat sink assembly is provided with connecting columns on both sides along the width direction of the front-end module, and the connecting columns are fixed to the mounting holes. The first surface faces the heat sink assembly, and a reinforcing plate is convexly provided on the second surface.

[0017] By providing the reinforcing plate, the structural strength of the sub-bracket is higher, so that the radiator assembly is fixed more firmly and has higher stability.

[0018] In some embodiments, the connector includes a first connecting plate and two second connecting plates. The two second connecting plates are respectively connected to opposite sides of the first connecting plate along the width direction, and the two second connecting plates are bent relative to the first connecting plate, and the bending directions of the two second connecting plates are the same. The end surface of one of the second connecting plates facing away from the other second connecting plate is laminated and fixed to the second surface, and the end surface of the first connecting plate facing away from the second connecting plate is fixed to the reinforcing plate.

[0019] It can be understood that the connecting member is U-shaped. When the sub-bracket is fixed to the frame, the connecting member wraps around the beam of the frame, and then the two second connecting plates are fixed to the beam using bolts. By setting the connecting member to be U-shaped, the connecting member can be more firmly fixed to the frame.

[0020] In some embodiments, the sub-bracket further includes a reinforcement member, one end of which is fixedly connected to a side of the reinforcement plate away from the fixing plate, and the other end of the reinforcement member is fixedly connected to a second connecting plate away from the fixing plate. By providing the reinforcement member, the structural strength of the sub-bracket is higher, so that the radiator assembly is fixed more firmly and has higher stability.

[0021] In some embodiments, the mounting member is provided with a weight-reducing hole, which passes through the first surface and the second surface. By providing the weight-reducing hole, the weight of the mounting member is reduced.

[0022] A second aspect of the present application provides a vehicle, comprising a frame and the front-end module provided in the first aspect of the present application, wherein the upper end of the radiator assembly is fixed to the frame via a first bracket, and the lower end of the radiator assembly is fixed to the frame via two sub-brackets.

[0023] The front-end module provided in the embodiment of the present application is provided by dividing the second bracket into two sub-brackets, the two sub-brackets are provided on both sides of the radiator assembly along the width direction, and the lower end of the radiator assembly is fixed by the two sub-brackets. Compared with the related art that uses an integrated bracket that runs through the entire bottom of the radiator to fix the lower end of the radiator, the two sub-brackets are smaller in size and occupy less space in the front cabin, making the space utilization rate of the front cabin higher and facilitating the layout of other structures and pipelines in the front cabin. In addition, the two sub-brackets are provided separately, and if the vehicle collides, local repairs can be performed, and the cost of repairs is lower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. For ease of understanding, the width direction of the front-end module is defined as the X-axis, the length direction of the front-end module is defined as the Y-axis, and the height direction of the front-end module is defined as the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. At the same time, the X-axis is the width direction of the vehicle, the Y-axis is the length direction of the vehicle, and the Z-axis is the height direction of the vehicle.

[0036] The directional terms such as "upper", "top", "lower", and "bottom" mentioned in the description of the embodiments of the present application are based on the Figure 1 The description of the orientation shown uses the positive direction of the Z axis as “up” and “top”, and the negative direction of the Z axis as “down” and “bottom”, which does not constitute a limitation on the front-end module 200 in actual application scenarios.

[0037] Please refer to Figure 1 The vehicle 1000 provided in the embodiment of the present application includes a frame 100 and a front-end module 200, wherein the front-end module 200 includes a first bracket 210, a second bracket 240 and a radiator assembly 290. The first bracket 210 and the second bracket 240 are separately arranged, and along the Z-axis direction, the first bracket 210 and the second bracket 240 are spaced apart, and the radiator assembly 290 is located between the first bracket 210 and the second bracket 240. The first bracket is used to fix the upper end of the radiator assembly to the frame. The second bracket 240 includes two sub-brackets 241, and the two sub-brackets 241 are separately arranged, and along the X-axis direction, the two sub-brackets 241 are spaced apart, and the two sub-brackets 241 are used to fix the lower end of the radiator assembly 290 to the frame.

[0038] Specifically, the vehicle frame 100 includes a front sub-frame 110, a front anti-collision beam 120 and a front cabin assembly 130. The front sub-frame 110 is located at the bottom, the front cabin assembly 130 is located on the side of the front sub-frame 110 facing the positive direction of the Z axis, and the front cabin assembly 130 is connected to the front sub-frame 110. The front anti-collision beam 120 is located on the side of the front sub-frame 110 facing the positive direction of the Z axis and on the side of the front cabin assembly 130 facing the negative direction of the Y axis, and the front anti-collision beam 120 is connected to the front cabin assembly 130.

[0039] Please refer to Figure 2 , Figure 3 and Figure 4 The first bracket 210 includes a main body 211. Along the X-axis direction, first fixing parts 212 are respectively provided on both sides of the main body 211. The first fixing parts 212 are plate-shaped. The first fixing parts 212 are fixed to the front cabin assembly 130 by bolts to fix the main body 211 to the front cabin assembly 130.

[0040] Please refer to Figure 2 , Figure 3 and Figure 5 Along the X-axis direction, first mounting portions 213 are respectively provided on both sides of the main body 211. The two first mounting portions 213 are located on the side of the main body 211 facing the second bracket 240, and the two first mounting portions 213 are spaced apart. The two first mounting portions 213 are located on both sides of the bottom of the main body 211, and the two first fixing portions 212 are located on both sides of the top of the main body 211.

[0041] The first mounting portion 213 is plate-shaped. The radiator assembly 290 includes a radiator 291 and two first mounting brackets 292. The first mounting brackets 292 are L-shaped brackets that can be formed by bending a sheet metal. Along the X-axis direction, the two first mounting brackets 292 are spaced apart on both sides of the radiator 291 along the width direction. One end of the two first mounting brackets 292 is fixedly connected to the upper end of the radiator 291, and the other end of the first mounting bracket 292 is fixed to the first mounting portion 213 by bolts to fix the upper end of the radiator 291 to the main body 211.

[0042] Please refer to Figure 6 and Figure 7 , along the X-axis direction, one of the sub-brackets 241 is fixed to one end of the front sub-frame 110 by bolts, and the other sub-bracket 241 is fixed to the other end of the front sub-frame 110 by bolts. The two sub-brackets 241 are separated and spaced apart along the X-axis direction. The lower end of the radiator assembly 290 is fixed to the two sub-brackets 241.

[0043] The front-end module 200 provided in this embodiment is provided by splitting the second bracket 240 into two sub-brackets 241, the two sub-brackets 241 are provided on both sides of the radiator assembly 290 along the width direction, and the lower end of the radiator assembly 290 is fixed to the front sub-frame 110 through the two sub-brackets 241. Compared with the related art in which the lower end of the radiator 291 is fixed by an integrated bracket running through the entire bottom of the radiator 291, the two sub-brackets 241 are smaller in size and occupy less space in the front cabin, so that the space utilization rate of the front cabin is higher and it is convenient for the layout of other structures and pipelines in the front cabin.

[0044] In addition, the two sub-brackets 241 are separately arranged, and if the vehicle 1000 collides, local repairs can be performed, and the cost of repairs is lower.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The first bracket 210 further includes a first leg 214 and a second leg 215. One end of the first leg 214 and the second leg 215 are connected to the side of the main body 211 facing the second bracket 240, and the first leg 214 and the second leg 215 are arranged at an angle, that is, the first leg 214 and the second leg 215 are located in the middle of the bottom of the main body 211. One end of the first leg 214 away from the main body 211 is connected to the frame 100, and one end of the second leg 215 away from the main body 211 is connected to the frame 100.

[0046] Specifically, when projected along the Y-axis direction, the first leg 214 and the second leg 215 are in an eight-shaped shape. Along the X-axis direction, the first leg 214 and the second leg 215 are connected to the side of the main body 211 facing the second bracket 240 at two ends that are closer to each other, and the first leg 214 and the second leg 215 are fixed to the front anti-collision beam 120 at two ends that are farther from each other by bolts.

[0047] It can be understood that the first leg 214 and the second leg 215 are supported on the front anti-collision beam 120, and the main body 211 obtains two supporting forces through the first leg 214 and the second leg 215, and the stability of the main body 211 is higher, so that the radiator assembly 290 can be fixed more firmly. In addition, the first leg 214, the second leg 215 and the front anti-collision beam 120 form a triangular structure, which makes the overall structural strength higher and the overall stability better.

[0048] In some embodiments, please refer to Figure 2 and Figure 5 The first mounting portion 213 includes a first mounting surface 216, and the first mounting surface 216 is concavely provided with a positioning groove 217. The heat sink assembly 290 has positioning protrusions 293 at both ends along the width direction. When the upper end of the heat sink assembly 290 is fixed to the first mounting portion 213, the positioning protrusions 293 are snapped into the positioning grooves 217.

[0049] Specifically, the first mounting surface 216 is one of the end surfaces in the thickness direction of the first mounting portion 213. The first mounting surface 216 faces the first mounting bracket 292, and the first mounting surface 216 is recessed with a positioning groove 217. The first mounting bracket 292 is provided with a positioning protrusion 293 protruding toward the first mounting surface 216. The positioning protrusion 293 is formed by bending a sheet metal, and the bending direction of the positioning protrusion 293 faces the positioning groove 217. When fixing the heat sink assembly 290 to the main body 211, the positioning protrusion 293 is first inserted into the positioning groove 217, and then the first mounting bracket 292 is fixed to the first mounting portion 213 with bolts.

[0050] By providing the positioning protrusion 293 and the positioning groove 217, it is convenient for the operator to position, so that the assembly speed is faster and the production efficiency is improved. In addition, the positioning protrusion 293 abuts the groove side of the positioning groove 217 to prevent the main body 211 and the radiator assembly 290 from shaking severely and preventing the bolts from loosening.

[0051] In some embodiments, please refer to Figure 2 The first support leg 214 and the second support leg 215 are located between the two first mounting portions 213 , and one end of the first support leg 214 and the second support leg 215 are connected to the middle of the body 211 along the width direction.

[0052] One end of the first support leg 214 and the second support leg 215 are connected to the middle part of the main body 211 along the width direction, and the supporting force acts on the middle part of the main body 211, so that the middle part of the main body 211 is supported and the main body 211 has higher stability.

[0053] In some embodiments, please refer to Figure 6 and Figure 7 The sub-bracket 241 includes a mounting member 242 and a connecting member 243, and the mounting member 242 and the connecting member 243 are fixedly connected. The connecting member 243 is fixed to the vehicle frame, and the radiator assembly 290 is fixed to two mounting members 242 on both sides along the width direction of the front end module 200.

[0054] The mounting member 242 and the connecting member 243 are formed by sheet metal processing, and the mounting member 242 and the connecting member 243 are fixed by welding to form the sub-bracket 241. That is, the sub-bracket 241 is processed separately, the structure is simple, and the processing cost is low. In addition, after the sub-bracket 241 is processed, it can be directly fixed on the front sub-frame 110. That is, the sub-bracket 241 is integrally arranged with the front sub-frame 110, and when the radiator assembly 290 is subsequently installed, the lower end of the radiator assembly 290 can be fixed to the mounting member 242, which reduces the installation process.

[0055] In some embodiments, please refer to Figure 7 , Figure 8 and Fig. 9 The mounting member 242 includes a fixing plate 244, and the fixing plate 244 includes a first surface 245 and a second surface 246 that are disposed opposite to each other. The fixing plate 244 is provided with a mounting hole 247 that penetrates the first surface 245 and the second surface 246. The heat sink assembly 290 is provided with connecting columns 294 on both sides along the width direction of the front-end module 200, respectively, and the connecting columns 294 are fixed to the mounting holes 247. The first surface 245 faces the heat sink assembly 290, and the second surface 246 is provided with a reinforcing plate 248 protruding therefrom.

[0056] The second surface 246 is provided with two reinforcing plates 248, which are located on both sides of the fixing plate 244 along the width direction. By providing the reinforcing plates 248, the structural strength of the sub-bracket 241 is higher, so that the radiator assembly 290 is fixed more firmly and has higher stability.

[0057] In some embodiments, please refer to Figure 8 and Fig. 9 The connecting member 243 includes a first connecting plate 249 and two second connecting plates 251. The two second connecting plates 251 are respectively connected to the two opposite sides of the first connecting plate 249 along the width direction, and the two second connecting plates 251 are bent relative to the first connecting plate 249. The bending directions of the two second connecting plates 251 are the same, and the second connecting plates 251 and the first connecting plate 249 form a 90-degree angle, that is, the two second connecting plates 251 and the first connecting plate 249 are connected in a U shape. The end face of one of the second connecting plates 251 facing away from the other second connecting plate 251 is laminated and fixed to the second surface 246, and the end face of the first connecting plate 249 facing away from the second connecting plate 251 is fixed to the reinforcing plate 248.

[0058] It can be understood that the connecting member 243 is U-shaped. When the sub-bracket 241 is fixed to the front sub-frame 110, the connecting member 243 wraps the beam of the front sub-frame 110, and then the two second connecting plates 251 are fixed to the beam using bolts. By setting the connecting member 243 to be U-shaped, the connecting member 243 can wrap the entire beam and fix it, and the connecting member 243 can be fixed to the frame more firmly.

[0059] In some embodiments, please refer to Figure 8 and Fig. 9 The sub-bracket 241 also includes a reinforcement member 252 , one end of which is fixedly connected to a side of the reinforcement plate 248 away from the fixing plate 244 , and the other end of the reinforcement member 252 is fixedly connected to a second connecting plate 251 away from the fixing plate 244 .

[0060] Specifically, the reinforcing plate 248 includes a first sub-plate 257 and a second sub-plate 258. The first sub-plate 257 and the second sub-plate 258 are connected along the length direction of the reinforcing plate 248. The first sub-plate 257 and the second sub-plate 258 can be integrally formed by sheet metal bending. In the direction away from the second sub-plate 258, the distance between the end surface of the first sub-plate 257 away from the fixed plate 244 and the fixed plate 244 gradually increases, that is, the end surface of the first sub-plate 257 away from the fixed plate 244 is an inclined surface. The end surface of the second sub-plate 258 away from the fixed plate 244 is parallel to the fixed plate 244.

[0061] The reinforcement member 252 includes a first reinforcement section 253, a second reinforcement section 254 and a third reinforcement section 255. Along the length direction of the reinforcement member 252, the second reinforcement section 254 is located between the first reinforcement section 253 and the third reinforcement section 255, and the first reinforcement section 253 and the third reinforcement section 255 are respectively connected to the two ends of the second reinforcement section 254. The extension direction of the first reinforcement section 253 and the third reinforcement section 255 is parallel to the fixed plate 244. Along the direction from the second sub-plate 258 to the first sub-plate 257, the distance between the end surface of the second reinforcement section 254 in the thickness direction and the fixed plate 244 gradually increases, that is, the second reinforcement section 254 is inclined relative to the fixed plate 244, and the second reinforcement section 254 is parallel to the end surface of the first sub-plate 257 away from the fixed plate 244.

[0062] It can be understood that the first reinforcement segment 253 and the third reinforcement segment 255 are bent relative to the second reinforcement segment 254, and the bending directions of the first reinforcement segment 253 and the third reinforcement segment 255 are opposite, that is, the reinforcement member 252 is Z-shaped.

[0063] The second reinforcing section 254 is welded and fixed to the end face of the first sub-plate 257 away from the fixed plate 244, and the third reinforcing section 255 is welded and fixed to the end face of the second sub-plate 258 away from the fixed plate 244. A gap is formed between the first reinforcing section 253 and the fixed plate 244, and the fixed plate 244, the reinforcing plate 248 and the first reinforcing section 253 enclose a U-shaped space, and the connecting member 243 is fixed in the U-shaped space. Among them, the first reinforcing section 253 is welded and fixed to the second connecting plate 251 away from the fixed plate 244.

[0064] By providing the reinforcing member 252, and welding and fixing the reinforcing member 252, the mounting member 242 and the connecting member 243 to each other, the sub-bracket 241 has a higher structural strength, so that the radiator assembly 290 is fixed more firmly and has higher stability.

[0065] In some embodiments, please refer to Figure 8 and Fig. 9 The mounting member 242 is provided with a weight-reducing hole 256, and the weight-reducing hole 256 passes through the first surface 245 and the second surface 246. By providing the weight-reducing hole 256, the weight of the mounting member 242 is reduced, so as to reduce the weight of the whole vehicle.

[0066] The embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
