Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts, and in particular relates to a radiator energy absorption structure, a front-end module having the same structure, and a vehicle. Background Technology

[0002] The radiator is a core component of a car's cooling system. It is typically installed at the front of the vehicle and is used to maintain the drive units (such as the engine) within a suitable operating temperature range. However, in high-speed collisions, such as frontal collisions, the rapid impact load can easily damage the radiator, compromising the vehicle's safety. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a radiator energy absorption structure, a front-end module thereon, and a vehicle, which can solve the problem that automobile radiators are easily damaged during high-speed collisions.

[0004] To achieve the above-mentioned technical objectives, the first aspect of this utility model provides a radiator energy-absorbing structure, including a lifting lug and an energy-absorbing block. The lifting lug is used to connect the radiator of a car and the front longitudinal beam of the car. The energy-absorbing block is located on the front side of the lifting lug and is used to absorb and disperse the load generated by the frontal collision when the car is involved in a frontal collision.

[0005] In one embodiment, the lifting lug includes a lifting lug body and an assembly portion disposed on the lifting lug body, and the energy-absorbing block includes a main body and a snap-fit ​​portion disposed on the main body. The energy-absorbing block is connected to the lifting lug by snapping the snap-fit ​​portion and the assembly portion.

[0006] In one embodiment, a slot extending along the thickness direction of the lug is formed in the assembly part, and a guide part and an abutment part are formed in the slot, wherein the guide part and the abutment part are connected or integrally formed.

[0007] In one embodiment, the extending directions of the guide portion and the abutment portion are perpendicular to each other.

[0008] In one embodiment, the energy-absorbing block further includes a clearance groove provided on the main body, the clearance groove and the snap-fit ​​portion being located on the same side of the energy-absorbing block.

[0009] In one embodiment, a snap-fit ​​protrusion is formed at one end of the snap-fit ​​portion away from the energy-absorbing block, protruding toward the assembly portion. When the snap-fit ​​portion is inserted into the slot, the guide portion abuts against the snap-fit ​​protrusion, causing the snap-fit ​​portion to elastically deform and swing toward the clearance groove.

[0010] In one embodiment, the energy-absorbing block further includes a limiting part located at the bottom of the clearance groove. When the energy-absorbing block is connected to the lifting lug, the bottom surface of the limiting part abuts against the top surface of the assembly part, and the snap-fit ​​protrusion abuts against the side of the abutting part away from the limiting part.

[0011] In one embodiment, the energy-absorbing block further includes a weight-reducing groove disposed on the main body.

[0012] A second aspect of this utility model provides a front-end module, including a heat sink and a heat sink energy-absorbing structure as described in the above technical solution, wherein the energy-absorbing block of the heat sink energy-absorbing structure is connected to the heat sink via the lifting lug.

[0013] A third aspect of this utility model provides a vehicle including a front bumper beam, a front longitudinal beam, and a front-end module as described in the above technical solution, wherein the front bumper beam is connected to the front-end module through the front longitudinal beam.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This invention, through the design concept of setting energy-absorbing blocks on the lugs used to connect the radiator and the front longitudinal beam of a car, allows the energy-absorbing blocks to absorb and disperse the load generated by the frontal collision by transferring the load generated by the collision to adjacent connecting parts (such as the lugs) and by absorbing the collision load through the collapse of their own shape (such as plastic deformation). This not only solves the problem that the radiator of a car is easily damaged in high-speed collisions, but also helps to improve the safety of the car. Attached Figure Description

[0036] The radiator is a core component of a car's cooling system. It is typically installed at the front of the vehicle and is used to maintain the drive units (such as the engine) within a suitable operating temperature range. However, in high-speed collisions, such as frontal collisions, the rapid impact load can easily damage the radiator, compromising the vehicle's safety.

[0037] To address the issue of car radiators being easily damaged during high-speed collisions, it is necessary to improve or optimize the existing component structure.

[0038] Example 1

[0039] Please see Figure 1 An embodiment of the first aspect of this utility model provides a radiator energy-absorbing structure, which includes a lug 1 and an energy-absorbing block 2. The lug 1 is used to connect the radiator of a vehicle to the front longitudinal beam of the vehicle. The energy-absorbing block 2 is installed on the front side of the lug 1, such as the directly front side of the lug 1, and is used to absorb and disperse the load generated by the frontal collision when the vehicle is involved in a frontal collision.

[0040] like Figures 2 to 4As shown, the hanger 1 includes a hanger body 11 and an assembly part 12 disposed on the hanger body 11. One end of the hanger body 11 is used to connect to the radiator of the vehicle, and the other end is used to connect to the front longitudinal beam of the vehicle. Specifically, the end of the hanger body 11 connected to the radiator of the vehicle has a first connecting hole 11a, and the other end connected to the front longitudinal beam of the vehicle has a second connecting hole 11b. The first connecting hole 11a and the second connecting hole 11b are used to engage with fastening elements (such as fastening bolts) to fix the hanger 1 to the radiator and the front longitudinal beam of the vehicle. It should be noted that the diameter of the second connecting hole 11b is larger than the diameter of the first connecting hole 11a. This facilitates the installation of vibration damping components (such as elastic damping components) in the second connecting hole 11b to improve the NVH (Noise, Vibration, Harshness) of the vehicle.

[0041] An assembly portion 12 is formed on the front side of the lifting lug body 11 for engaging with the energy-absorbing block 2. A slot 13 is formed within the assembly portion 12, and a guide portion 14 and an abutment portion 15 are formed within the slot 13. The slot 13 extends along the thickness direction of the lifting lug body 11. Specifically, the slot 13 is formed by the enclosure of a left side plate 12a, a right side plate 12b, and a front side plate 12c connected between the left side plate 12a and the right side plate 12b, all formed on the front outer surface of the lifting lug body 11. The length directions of the left side plate 12a and the right side plate 12b are the same as the thickness direction of the lifting lug body 11, and the end of the left side plate 12a is flush with the corresponding ends of the right side plate 12b and the front side plate 12c. Thus, when the front side plate 12c is connected to the front outer surface of the lug body 11 via the left side plate 12a and the right side plate 12b, the left side plate 12a and the right side plate 12b are arranged with a certain distance between them, thereby forming a groove 13 extending along the thickness direction of the lug body 11 on the front side. The guide portion 14 extends from the front outer surface of the lug body 11 along the thickness direction of the lug body 11, is in the shape of a protrusion, and is formed at the bottom of the groove 13. The abutment portion 15 extends from the front outer surface of the lug body 11 along the length direction of the lug body 11, is also in the shape of a protrusion, and is formed at the bottom of the groove 13. Preferably, one end of the guide portion 14 and the middle part of the abutment portion 15 are connected or integrally formed.

[0042] Furthermore, the lifting lug 1 also includes a reinforcing portion 16 to improve the structural strength of the lifting lug 1 itself. Specifically, the reinforcing portion 16 is formed on the upper surface of the lifting lug body 11 and is in the form of a rib. In some embodiments, there may be multiple reinforcing portions 16. In this first embodiment, there are two reinforcing portions 16, which are arranged opposite to each other along the width direction of the lifting lug body 11.

[0043] like Figure 2 , Figure 5 As shown, the energy-absorbing block 2 includes a main body 21 and a snap-fit ​​portion 22 provided on the main body 21. The main body 21 is rectangular, and the snap-fit ​​portion 22 is hook-shaped. Specifically, the snap-fit ​​portion 22 extends along the thickness direction of the main body 21, with one end connected to the top of the main body 21 and the other end being a snap-fit ​​protrusion extending towards the mounting portion 12, allowing the energy-absorbing block 2 to connect to the lifting lug 1 through the snap-fit ​​between the snap-fit ​​portion 22 and the mounting portion 12. It should be noted that, to achieve the connection between the energy-absorbing block 2 and the lifting lug 1, the main body 21 is provided with a clearance groove 23. The clearance groove 23 extends along the thickness direction of the main body 21, that is, extends vertically downwards, and the opening of the clearance groove 23 is located on the bottom outer surface of the main body 21. Preferably, the clearance groove 23 and the snap-fit ​​portion 22 are located on the same side of the energy-absorbing block 2. When the snap-fit ​​part 22 is inserted into the slot 13 in the vertical direction, the guide part 14 causes the snap-fit ​​part 22 to undergo elastic deformation and swing the snap-fit ​​part 22 into the clearance slot 23 to a certain angle.

[0044] Furthermore, the energy-absorbing block 2 also includes a limiting part 24. Specifically, the limiting part 24 is in the shape of a protrusion, formed at the bottom of the clearance groove 23, and extends along the thickness direction of the main body 21.

[0045] Furthermore, to reduce the mass of the energy-absorbing block 2 itself, the energy-absorbing block 2 also includes a weight-reducing groove 25. Specifically, the opening of the weight-reducing groove 25 is located on the bottom outer surface of the main body 21 and extends along the thickness direction of the main body 21. In some embodiments, there may be multiple weight-reducing grooves 25. In this first embodiment, there are eight weight-reducing grooves 25, which are equally spaced on the main body 21.

[0046] Thus, as Figure 6 , Figure 7 As shown, when the energy-absorbing block 2 is connected to the lifting lug 1, the front side plate 12c of the assembly part 12 is installed in the clearance groove 23, and the snap-fit ​​part 22 is installed in the snap-fit ​​groove 13. The top outer surface of the front side plate 12c abuts against the bottom surface of the limiting part 24, one end of the snap-fit ​​part 22 abuts against the bottom surface of the abutment part 15, and the rear outer end face of the energy-absorbing block 2 makes surface-to-surface contact with the front outer end face of the lifting lug 1. Preferably, the fit between the front side plate 12c and the clearance groove 23 is an interference fit. This facilitates the stable and reliable installation of the energy-absorbing block 2 on the lifting lug 1.

[0047] It is worth mentioning that when the energy-absorbing block 2 is engaged with the lifting lug 1 from top to bottom, the end of the engaging part 22 that abuts against the bottom surface of the abutting part 15 first comes into contact with the outer surface of the guide part 14, causing the engaging part 22 to elastically deform and move into the clearance groove 23. Figure 7As shown, during the clockwise swing, when the end of the engaging portion 22 passes the guide portion 14 and the abutment portion 15, it no longer bears the abutment action of clockwise swinging towards the clearance groove 23, and the engaging portion 22 has the potential energy to return to its original state. At this time, the engaging portion 22 will move outward from the clearance groove 23 as follows: Figure 7 The counterclockwise swing is shown to a certain angle so as to abut against the side of the abutment part 15 away from the limiting part 24. At the same time, the bottom surface of the limiting part 24 abuts against the top surface of the assembly part 12, that is, the bottom surface of the limiting part 24 abuts against the top surface of the front side plate 12c, thereby realizing the snap-fit ​​connection between the energy-absorbing block 2 and the lifting lug 1.

[0048] Example 2

[0049] like Figure 8 As shown, an embodiment of the second aspect of this utility model provides a front-end module, which includes a heat sink 3 and a heat sink energy-absorbing structure as described in Embodiment 1. The energy-absorbing block 2 of the heat sink energy-absorbing structure is connected to the heat sink 3 via a lifting lug 1, giving the front-end module high impact resistance.

[0050] It should be noted that the radiator 3 mentioned here is typically installed at the front of the car and works in conjunction with components such as the fan, water pump, and thermostat. Specifically, the radiator 3 can be composed of three parts: the radiator core, the water tank body, and the inlet / outlet pipes. The radiator core, the core component of the radiator 3, is usually composed of thin-walled copper pipes and aluminum fins, forming a channel for the flow of coolant (such as soft water) and facilitating heat exchange through contact with air. The water tank body, serving as the outer shell of the radiator 3, is usually made of plastic or metal and protects the radiator core, securing it to the vehicle's front air intake. The inlet / outlet pipes connect the radiator 3 to the drive unit (such as the engine), responsible for introducing coolant into the radiator core for cooling and returning the cooled coolant to the drive unit for circulation. This ensures that the drive unit operates within a suitable temperature range.

[0051] Example 3

[0052] like Figure 9 , Figure 10As shown, an embodiment of the third aspect of this utility model provides a vehicle including a front longitudinal beam 4, a front anti-collision beam 5, and a front-end module as described in Embodiment 2. The front anti-collision beam 5 is connected to the front-end module via the front longitudinal beam 4, giving the vehicle higher safety performance. It should be noted that, viewed from the length direction of the vehicle, the energy-absorbing block 2 is located between the front anti-collision beam 5 and the radiator 3, and is closer to the front anti-collision beam 5 than to the radiator 3. This causes the front anti-collision beam 5 and the front longitudinal beam 4 to form a first protective structure for the radiator 3, and the energy-absorbing block 2 and the hanger 1 to form a second protective structure for the radiator 3. Thus, in the event of a frontal collision, compared to the prior art, because the front end of the vehicle has two protective structures for absorbing and dispersing the load generated by the frontal collision, the problem of the radiator 3 being easily damaged in high-speed collisions can be solved.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
