Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and more particularly to a radiator assembly mounting structure and vehicle. Background Technology

[0002] As people's living standards continue to improve, vehicles are no longer just a means of transportation. People's demands for car quality are constantly increasing, and vehicle comfort and safety have become key areas of competition among car companies.

[0003] When converting an EV model to a PHEV model, the radiator is mounted on the radiator frame on both sides, and the radiator frame is mounted on the longitudinal beams of the vehicle body on both sides. This results in a low dynamic stiffness (referring to the ability of a structure to resist deformation under specific dynamic disturbances) at the mounting points of the radiator on the radiator frame, leading to higher acceleration noise and affecting the overall vehicle comfort. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a radiator assembly mounting structure and vehicle to improve the dynamic stiffness of the mounting point of the radiator on the radiator frame, reduce the noise during vehicle acceleration, and improve vehicle comfort.

[0005] The first aspect of this application provides a radiator assembly mounting structure, including:

[0006] The main frame includes two main longitudinal beams;

[0007] The front subframe is connected to the main frame and has two secondary longitudinal beams;

[0008] A radiator assembly includes a radiator and a radiator frame, the radiator being mounted on the radiator frame, and the radiator frame being connected to two main longitudinal beams and two secondary longitudinal beams.

[0009] The radiator assembly mounting structure provided in this application has a front subframe connected to the main frame, and the front subframe has two secondary longitudinal beams. The radiator of the radiator assembly is mounted on the radiator frame, which is connected to both main longitudinal beams and also to the two secondary longitudinal beams. In other words, by optimizing the mounting method of the radiator frame, it is connected to both main longitudinal beams and the two secondary longitudinal beams of the front subframe. This reduces the relative distance between the mounting point of the radiator and the mounting point of the radiator frame, thereby increasing the dynamic stiffness of the mounting point of the radiator on the radiator frame. This improves the ability of the mounting point to resist deformation under specific dynamic disturbances, thus reducing noise during acceleration in vehicles with this radiator assembly mounting structure and improving vehicle comfort.

[0010] In some embodiments, the radiator assembly mounting structure further includes:

[0011] The mounting plate is provided in two parts, and the two mounting plates are respectively disposed at the front end of the two secondary longitudinal beams. The mounting plates are adapted to install the radiator frame.

[0012] The radiator frame is mounted on the sub-longitudinal beam via a mounting plate. Compared to directly fixing the radiator frame to the subframe, the mounting plate allows for easier adaptation to different fixing methods and positions of the radiator frame, simplifying its secure installation. For example, if the radiator frame is bolted, holes would need to be drilled in the sub-longitudinal beam, affecting its structural strength. With the mounting plate, the sub-longitudinal beam can be welded to the mounting plate, and holes can be drilled in the mounting plate itself, thus avoiding the need for drilling in the sub-longitudinal beam and ensuring its structural strength. Furthermore, the mounting plate can act as an extension of the sub-longitudinal beam to accommodate different radiator frame mounting positions. For instance, if the distance between two mounting positions of the radiator frame is greater than the distance between two sub-longitudinal beams in the left-right direction of the vehicle, it would be difficult to mount the radiator frame onto the sub-longitudinal beams. The mounting plate can then serve as an intermediate connector to link the radiator frame and the sub-longitudinal beams.

[0013] In some embodiments, the mounting plate includes a connecting portion connected to the heat sink frame, and a flange is formed at the circumferential edge of the connecting portion.

[0014] With this configuration, the mounting plate is connected to the secondary longitudinal beam via a connecting part, and the circumferential edge of the connecting part has a flange, which can improve the structural strength of the connecting part and the connection stability between the connecting part and the radiator frame.

[0015] In some embodiments, the connecting portion has a mounting area protruding toward the radiator frame, and the connecting portion has through holes in the mounting area for fasteners connecting to the radiator frame to pass through.

[0016] With this configuration, the connecting part has the aforementioned mounting area, which ensures the machining accuracy of the mounting area. For example, the mounting area has a mounting surface, which is small in area compared to the surface of the entire connecting part, thereby improving the planar accuracy of the mounting surface and ensuring a tight fit between the mounting surface and the radiator frame.

[0017] In some embodiments, the through hole is a strip-shaped hole extending in a vertical direction.

[0018] This design allows the vertical position of the radiator frame to be adjusted via the slotted holes, which helps to ensure that the left and right sides of the radiator frame are at the same vertical height.

[0019] In some embodiments, the mounting plate includes a mounting portion connected to the secondary longitudinal beam, the mounting portion covering the front opening of the secondary longitudinal beam.

[0020] With this configuration, the mounting plate is connected to the sub-longitudinal beam via the mounting section, and the mounting section seals the front opening of the sub-longitudinal beam. This prevents foreign objects on the road, such as stones, from entering the sub-longitudinal beam and causing abnormal noises during vehicle operation.

[0021] In some embodiments, the mounting portion is welded to the secondary longitudinal beam;

[0022] And / or, the mounting part is provided with a weight reduction hole.

[0023] By connecting the mounting section and the sub-longitudinal beam through welding, the structural strength of the sub-longitudinal beam can be avoided by drilling holes in it. Furthermore, the inclusion of weight-reducing holes helps reduce the weight of the mounting plate, thereby contributing to a reduction in the overall vehicle weight.

[0024] In some embodiments, the front subframe further includes a sub-crossbeam, the two ends of which are respectively connected to the two sub-longitudinal beams.

[0025] By incorporating a secondary crossbeam, which connects the two secondary longitudinal beams, the rigidity of the subframe can be improved, while also enhancing the vehicle's ability to withstand offset collisions.

[0026] In some embodiments, the secondary crossbeam includes two connecting segments and an intermediate segment located between the two connecting segments, the two connecting segments being respectively connected to the two secondary longitudinal beams, and the connecting segments extending obliquely downward from the connection point with the secondary longitudinal beams.

[0027] With this configuration, the sub-beam forms a structure that is high at both ends and low in the middle in the left-right direction of the vehicle. This not only avoids the radiator pipes and facilitates their arrangement, but also allows the sub-beam to buffer and absorb energy through deformation in offset collisions, thereby improving the vehicle's performance in offset collisions.

[0028] In addition, the aforementioned sub-beam also provides protection for the powertrain, preventing foreign objects from impacting it to a certain extent. Specifically, the sub-beam is located at the front of the powertrain, and its relatively low middle section provides some protection to the front of the powertrain.

[0029] A second aspect of this application provides a vehicle including a radiator assembly mounting structure as described in any of the preceding claims.

[0030] The vehicle has the beneficial effects of the aforementioned radiator assembly mounting structure. Attached Figure Description

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0045] The chassis is a crucial load-bearing component of a vehicle, typically consisting of two main longitudinal beams and multiple main crossbeams connecting the two main longitudinal beams. Most of the vehicle's components or assemblies are located on the chassis, such as the front suspension assembly, rear axle assembly, powertrain, and cargo box.

[0046] When converting an EV (Electric Vehicle) model to a PHEV (Plug-in Hybrid Electric Vehicle) model, the radiator assembly is also mounted on the two main longitudinal beams. The radiator assembly includes the radiator and the radiator frame. The radiator is mounted on the radiator frame on both sides, and the radiator frame is mounted on the two main longitudinal beams on both sides. This low radiator placement and relatively large distance between the radiator mounting point and the radiator frame mounting point result in low dynamic stiffness (the ability of a structure to resist deformation under specific dynamic disturbances), leading to higher acceleration noise and impacting overall vehicle comfort.

[0047] Based on this, some embodiments of this application provide a radiator assembly mounting structure that connects the radiator frame 32 of the radiator assembly 3 to the sub-longitudinal beam 21 of the front subframe 2 of the vehicle, thereby shortening the distance between the mounting point of the radiator 31 and the mounting point of the radiator frame 32, increasing the dynamic stiffness of the mounting point of the radiator 31 on the radiator frame 32, thereby helping to reduce noise and improve the overall comfort of the vehicle.

[0048] Reference Figures 1 to 6 Some embodiments of this application provide a radiator assembly mounting structure, including a main frame 1, a front subframe 2, and a radiator assembly 3.

[0049] The main frame 1 includes two main longitudinal beams 11.

[0050] The aforementioned front subframe 2 is connected to the main frame 1, and the front subframe 2 has two secondary longitudinal beams 21. The two secondary longitudinal beams 21 are spaced apart in the left-right direction of the vehicle, and the secondary longitudinal beams 21 extend along the front-rear direction of the vehicle.

[0051] The aforementioned radiator assembly 3 includes a radiator 31 and a radiator frame 32. The radiator 31 is mounted on the radiator frame 32, and the radiator frame 32 is connected to two main longitudinal beams 11 and two secondary longitudinal beams 21.

[0052] It should be noted that, referring to Figure 1 As shown, two main longitudinal beams 11 are spaced apart in the left-right direction of the vehicle, and the main longitudinal beams 11 extend along the front-rear direction of the vehicle. Among them, Figure 1 The direction indicated by the double-headed arrow X in the figure represents the front-to-back direction of the vehicle, which is also the front-to-back direction of the main longitudinal beam 11. Figure 1 The double-headed arrow Y in the diagram indicates the left-right direction of the vehicle, which is also the width direction of the main longitudinal beam 11.

[0053] Among them, reference Figure 2 The connection point between the radiator frame 32 and the main longitudinal beam 11 is located above the connection point between the radiator frame 32 and the secondary longitudinal beam 21. Compared with the radiator frame 32 being connected only to the main longitudinal beam 11, this can improve the installation stability of the radiator 31, thereby increasing the dynamic stiffness of the mounting point of the radiator 31 on the radiator frame 32.

[0054] The radiator assembly mounting structure provided in this application embodiment has a front subframe 2 connected to a main frame 1, and the front subframe 2 has two secondary longitudinal beams 21. The radiator 31 of the radiator assembly 3 is mounted on a radiator frame 32, which is connected to two main longitudinal beams 11 and simultaneously connected to the two secondary longitudinal beams 21. In other words, by optimizing the mounting method of the radiator frame 32, while connecting the radiator frame 32 to the two main longitudinal beams 11, it also connects the radiator frame 32 to the two secondary longitudinal beams 21 of the front subframe 2. This reduces the relative distance between the mounting point of the radiator 31 and the mounting point of the radiator frame 32, increasing the dynamic stiffness of the mounting point of the radiator 31 on the radiator frame 32. This improves the ability of the mounting point of the radiator 31 to resist deformation under specific dynamic disturbances, thereby reducing noise during vehicle acceleration and improving vehicle comfort.

[0055] Reference Figure 2 and Figure 5 The aforementioned secondary crossbeam 22 includes two connecting sections 221 and an intermediate section 222 located between the two connecting sections 221. The two connecting sections 221 are respectively connected to the two secondary longitudinal beams 21, and the connecting section 221 extends downward at an incline from the connection point with the secondary longitudinal beam 21.

[0056] Understandably, the sub-beam 22 forms a structure that is high at both ends and low in the middle in the left-right direction of the vehicle. This not only avoids the pipes of the radiator 31 and facilitates the arrangement of the pipes of the radiator 31, but also allows the deformation of the sub-beam 22 to buffer and absorb energy in the case of offset collision, thereby improving the vehicle's performance in offset collision.

[0057] Furthermore, the aforementioned sub-crossbeam 22 also provides protection for the powertrain, preventing foreign objects from impacting it to a certain extent. Located in front of the powertrain, the relatively low middle section 222 of the sub-crossbeam 22 provides some protection to the powertrain from the front. However, the height of the middle section 222 of the sub-crossbeam 22 is not necessarily better the lower it is; it is set at a reasonable height based on the actual vehicle model. This not only provides some protection for the powertrain but also allows the vehicle to adapt to more road conditions.

[0058] In addition, the aforementioned secondary crossbeam 22 is a tubular beam, which can be formed by bending it with a pipe bending machine and stamping it with a stamping die. It has a lower weight and lower cost.

[0059] For example, the aforementioned tube beam can be selected as having a diameter of 70 mm and a wall thickness of 1.2 mm. Of course, the diameter and wall thickness of the tube beam can also be selected according to actual needs. No specific restrictions are imposed here.

[0060] In addition, the connecting section 221 of the aforementioned tube beam is welded to the secondary longitudinal beam 21. In this way, the end edge of the tube beam can be bent by means of stamping, extrusion, etc., so that a curved weld can be formed after welding with the secondary longitudinal beam 21, which can increase the length of the weld and improve the connection strength between the tube beam and the secondary longitudinal beam 21.

[0061] In some embodiments, refer to Figures 4 to 6 The radiator assembly mounting structure also includes mounting plates 4. There are two mounting plates 4, which are respectively located at the front ends of the two secondary longitudinal beams 21. The mounting plates 4 are suitable for mounting the radiator frame 32.

[0062] Understandably, the radiator frame 32 is mounted on the secondary longitudinal beam 21 via the mounting plate 4. Compared to the radiator frame 32 being directly fixed to the secondary longitudinal beam 21, the mounting plate 4 can be used to adapt to the fixing method and position of the radiator frame 32, making it easier to fix the radiator frame 32.

[0063] For example, if the radiator frame 32 is fixed with bolts, holes would need to be drilled in the sub-longitudinal beam 21 to secure it, affecting the structural strength of the sub-longitudinal beam 21. However, by using the mounting plate 4, the sub-longitudinal beam 21 can be welded to the mounting plate 4, and holes can be drilled in the mounting plate 4, thus avoiding drilling holes in the sub-longitudinal beam 21 and ensuring its structural strength. Of course, the mounting plate 4 is designed as an extension structure of the sub-longitudinal beam 21 to adapt to the installation position of the radiator frame 32. For example, in the left-right direction of the vehicle, the distance between the two installation positions of the radiator frame 32 is greater than the distance between the two sub-longitudinal beams 21. In this case, it would be difficult to install the radiator frame 32 onto the sub-longitudinal beam 21. The mounting plate 4 can serve as an intermediate connector to achieve the connection between the radiator frame 32 and the sub-longitudinal beam 21.

[0064] Reference Figures 4 to 6 The mounting plate 4 mentioned above includes a mounting part 42 connected to the secondary longitudinal beam 21, and the mounting part 42 covers the front opening of the secondary longitudinal beam 21.

[0065] Understandably, the mounting plate 4 is connected to the sub-longitudinal beam 21 through the mounting part 42, and the mounting part 42 covers the front opening of the sub-longitudinal beam 21, so as to prevent foreign objects on the road, such as stones, from entering the sub-longitudinal beam 21 and causing abnormal noise during vehicle operation.

[0066] For example, the mounting portion 42 is provided with weight reduction holes 421. The provision of weight reduction holes 421 can help reduce the weight of the mounting plate 4, thereby helping to reduce the overall weight of the vehicle. The number and diameter of the weight reduction holes 421 can be set according to actual needs, and are not specifically limited here.

[0067] It should be noted that the setting of the weight reduction hole 421 will not affect the sealing of the front opening of the sub-longitudinal beam 21 by the mounting part 42. At this time, the diameter of the weight reduction hole 421 can be set relatively small, so as to achieve the effect of weight reduction while preventing foreign objects from entering the sub-longitudinal beam 21.

[0068] For example, the mounting part 42 is welded to the secondary longitudinal beam 21. By connecting the mounting part 42 and the secondary longitudinal beam 21 by welding, it is possible to avoid affecting the structural strength of the secondary longitudinal beam 21 by opening holes in it, and the connection strength between the mounting part 42 and the secondary longitudinal beam 21 can be improved.

[0069] The aforementioned secondary longitudinal beam 21 is a rectangular beam, and the mounting part 42 is welded to at least two sides of the rectangular beam. Specifically, refer to... Figure 6 The aforementioned mounting part 42 is welded to two opposite sides of the rectangular beam, thus forming two welds between the mounting part 42 and the rectangular beam.

[0070] Optionally, to enhance the connection strength between the mounting part 42 and the secondary longitudinal beam 21, the number of welded connections between the mounting part 42 and the rectangular beam can be increased, for example, the mounting part 42 can be welded to three or four sides of the rectangular beam. Alternatively, a reinforcing plate can be added between the mounting part 42 and the secondary longitudinal beam 21, with the reinforcing plate spaced circumferentially along the secondary longitudinal beam 21. Alternatively, a flange can be provided at the circumferential edge of the mounting part 42, ensuring a large contact area between the mounting part 42 and the secondary longitudinal beam 21. The flange is welded to the secondary longitudinal beam 21, thereby improving the connection strength between the mounting part 42 and the secondary longitudinal beam 21. Furthermore, the mounting part 42 can also have an extension extending into the secondary longitudinal beam 21, inserted into the secondary longitudinal beam 21 through the front opening of the secondary longitudinal beam 21, with the extension fitting against the inner wall of the secondary longitudinal beam 21. This also improves the connection strength between the mounting part 42 and the secondary longitudinal beam 21, allowing the mounting plate 4 to better support the radiator frame 32.

[0071] Reference Figures 4 to 6 The mounting plate 4 also includes a connecting part 41 connected to the heat sink frame 32, and a flange 411 is formed at the circumferential edge of the connecting part 41.

[0072] Understandably, the mounting plate 4 is connected to the secondary longitudinal beam 21 through the connecting part 41, and the connecting part 41 has a flange 411 at its circumferential edge, which can improve the structural strength of the connecting part 41 and improve the support stability of the connecting part 41 for the radiator frame 32.

[0073] The aforementioned flange 411 can be a whole extending circumferentially along the connecting portion 41, or it can include multiple segments, with the multiple flange segments spaced apart circumferentially along the connecting portion 41.

[0074] For example, refer to Figure 6 The connecting portion 41 has a mounting area 412 protruding toward the radiator frame 32, and the connecting portion 41 has a through hole 4121 in the mounting area 412 for fasteners connecting to the radiator frame 32 to pass through. In this case, the flange 411 extends away from the radiator frame 32, thus preventing the flange 411 from affecting the contact between the mounting area 412 and the radiator frame 32.

[0075] Understandably, the connecting part 41 has the aforementioned mounting area 412, which ensures the machining accuracy of the mounting area 412. For example, the mounting area 412 has a mounting surface, which is small in area relative to the surface of the entire connecting part 41, thereby improving the planar accuracy of the mounting surface and ensuring a tight fit between the mounting surface and the heat sink frame 32.

[0076] The fasteners mentioned above can be bolts, which pass through the through hole 4121 to connect the radiator frame 32. That is, the connecting part 41 and the radiator frame 32 are connected by bolts, making the radiator frame 32 detachable from the connecting part 41, which facilitates the installation and removal of the radiator frame 32. Moreover, in order to improve the stability of the bolt, a spring is provided between the bolt head and the connecting part 41.

[0077] Furthermore, the aforementioned through hole 4121 is preferably a strip-shaped hole extending vertically. This design allows adjustment of the vertical position of the radiator frame 32 via the strip-shaped hole, which helps to ensure that the left and right sides of the radiator frame 32 are at the same vertical height. Of course, the aforementioned through hole 4121 can also be configured as a strip-shaped hole extending horizontally, thus allowing adjustment of the horizontal position of the radiator frame 32 via the strip-shaped hole.

[0078] It should be noted that the aforementioned mounting plate 4 is a sheet metal part, with the connecting part 41 and the mounting part 42 integrally formed, resulting in high structural strength and ease of installation. The mounting area 412 of the connecting part 41 can be formed by stamping, thus creating a groove on the other side of the connecting part 41. This not only forms the mounting area 412, improving the machining accuracy of the mounting area 412, but also enhances the structural strength of the connecting part 41 by adding a bending structure, thereby improving the stability of the connecting part 41 in supporting the radiator frame 32.

[0079] In addition, refer to Figure 6 The connecting part 41 of the mounting plate 4 is located outside the mounting part 42. That is, in the left-right direction of the vehicle, the connecting part 41 is closer to the outside of the vehicle than the mounting part 42. Thus, the mounting point of the radiator frame 32 is extended outward by the mounting plate 4. At this time, the mounting plate 4 is equivalent to the extension of the sub-longitudinal beam 21 extending outward in the left-right direction of the vehicle. This allows the radiator frame 32 to be mounted on the sub-longitudinal beam 21 without adjusting the structure of the sub-longitudinal beam 21 or the structure of the radiator frame 32.

[0080] Furthermore, in the left-right direction of the vehicle, the overall width of the connecting part 41 is smaller than the overall width of the mounting part 42, ensuring the connection strength between the mounting plate 4 and the sub-longitudinal beam 21. In the height direction of the vehicle (i.e., the vertical direction), the overall length of the connecting part 41 is greater than the overall length of the mounting part 42. This not only improves the vertical structural strength of the connecting part 41, but also facilitates the arrangement of the through holes of the aforementioned vertically extending strip-shaped holes, thereby extending and expanding the sub-longitudinal beam 21 vertically to realize the installation of the radiator frame 32.

[0081] In some embodiments, the aforementioned front subframe 2 further includes a sub-crossbeam 22, the two ends of which are respectively connected to two sub-longitudinal beams 21.

[0082] Understandably, by setting up a sub-crossbeam 22, which connects the two sub-longitudinal beams 21, the rigidity of the front subframe 2 can be improved, and the vehicle's offset collision resistance can be improved.

[0083] Reference Figures 1 to 6 For example, a radiator assembly mounting structure is provided, which includes a main frame 1, a front subframe 2 and a radiator assembly 3.

[0084] The main frame 1 includes two main longitudinal beams 11. The main longitudinal beams 11 extend along the longitudinal direction of the vehicle, and the two main longitudinal beams 11 are spaced apart in the left-right direction of the vehicle. Figure 1 The direction indicated by the double-headed arrow X in the figure represents the front-to-back direction of the vehicle, which is also the front-to-back direction of the main longitudinal beam 11. Figure 1 The double-headed arrow Y in the diagram indicates the left-right direction of the vehicle, which is also the width direction of the main longitudinal beam 11.

[0085] The aforementioned front subframe 2 is connected to the main frame 1, and the front subframe 2 has two secondary longitudinal beams 21. The two secondary longitudinal beams 21 are spaced apart in the left-right direction of the vehicle, and the secondary longitudinal beams 21 extend along the front-rear direction of the vehicle.

[0086] The aforementioned radiator assembly 3 includes a radiator 31 and a radiator frame 32. The radiator 31 is mounted on the radiator frame 32, and the radiator frame 32 is connected to two main longitudinal beams 11 and two secondary longitudinal beams 21.

[0087] The above-mentioned radiator assembly mounting structure also includes mounting plates 4. There are two mounting plates 4, which are respectively located at the front end of the two secondary longitudinal beams 21. The mounting plates 4 are suitable for mounting the radiator frame 32.

[0088] The mounting plate 4 includes a mounting portion 42 connected to the secondary longitudinal beam 21, which covers the front opening of the secondary longitudinal beam 21. The mounting portion 42 has a weight-reducing hole 421 and is welded to the secondary longitudinal beam 21.

[0089] The aforementioned secondary longitudinal beam 21 is a rectangular beam, and the mounting part 42 is welded to at least two sides of the rectangular beam. Specifically, refer to... Figure 6 The aforementioned mounting part 42 is welded to two opposite sides of the rectangular beam, thus forming two welds between the mounting part 42 and the rectangular beam.

[0090] The mounting plate 4 includes a connecting portion 41 that connects to the heat sink frame 32, and a flange 411 is formed at the circumferential edge of the connecting portion 41. The flange 411 is an integral part extending circumferentially along the connecting portion 41.

[0091] The aforementioned connecting portion 41 has a mounting area 412 protruding toward the radiator frame 32, and a through hole 4121 is provided on the connecting portion 41 in the mounting area 412 for a fastener to be connected to the radiator frame 32 to pass through. The fastener may be a bolt, which passes through the through hole 4121 to connect to the radiator frame 32.

[0092] The aforementioned mounting plate 4 is a sheet metal part, with the connecting part 41 and the mounting part 42 integrally formed, resulting in high structural strength and easy installation.

[0093] The connecting portion 41 of the mounting plate 4 is located on the outside of the mounting portion 42. That is, in the left-right direction of the vehicle, the connecting portion 41 is closer to the outside of the vehicle than the mounting portion 42. Thus, the mounting point of the radiator frame 32 is extended outward by the mounting plate 4. At this time, the mounting plate 4 is equivalent to the extension of the sub-longitudinal beam 21 extending outward in the left-right direction of the vehicle. This allows the radiator frame 32 to be mounted on the sub-longitudinal beam 21 without adjusting the structure of the sub-longitudinal beam 21 or the structure of the radiator frame 32.

[0094] Furthermore, in the left-right direction of the vehicle, the overall width of the connecting part 41 is smaller than the overall width of the mounting part 42, ensuring the connection strength between the mounting plate 4 and the sub-longitudinal beam 21. In the height direction of the vehicle (i.e., the vertical direction), the overall length of the connecting part 41 is greater than the overall length of the mounting part 42. This not only improves the vertical structural strength of the connecting part 41, but also facilitates the arrangement of the through holes of the aforementioned vertically extending strip-shaped holes, thereby extending and expanding the sub-longitudinal beam 21 vertically to realize the installation of the radiator frame 32.

[0095] The aforementioned front subframe 2 also includes a sub-crossbeam 22, with both ends of the sub-crossbeam 22 connected to two sub-longitudinal beams 21 respectively. The sub-crossbeam 22 includes two connecting sections 221 and an intermediate section 222 located between the two connecting sections 221. The two connecting sections 221 are respectively connected to the two sub-longitudinal beams 21, and the connecting sections 221 extend downward at an angle from the connection point with the sub-longitudinal beams 21.

[0096] Among them, the secondary crossbeam 22 is made of tubular beam, which is low in cost and weight.

[0097] Other embodiments of this application provide a vehicle including a radiator assembly mounting structure as described in any of the above embodiments, thus having the beneficial effects of the radiator assembly mounting structure described in any of the above embodiments, which will not be repeated here.

[0098] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
