Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a chassis and a vehicle. Background Technology

[0002] To meet the needs of customers with larger vehicle spaces, it is necessary to rationally design the front overhang length, rear overhang length, and wheelbase. That is, to increase interior space with a shorter front / rear overhang and a longer wheelbase. However, a shorter front overhang will lead to a reduction in space. Consequently, when arranging the same functional modules, the arrangement space between each functional module will inevitably become more compact. Furthermore, since each functional module requires a corresponding mounting bracket for its arrangement, it is not conducive to meeting the clearance requirements between functional modules, nor is it conducive to reducing the overall vehicle weight. Utility Model Content

[0003] The main purpose of this invention is to propose a chassis and vehicle that meets the clearance requirements between the front bumper and the cooling module, while reducing the overall vehicle weight.

[0004] To achieve the above objectives, the chassis proposed in this utility model includes:

[0005] Front subframe, including the front crossbeam;

[0006] A support mount, connected to the front side of the front crossbeam, is used to mount the front bumper; and

[0007] A cooling module is installed on the support mounting component.

[0008] In one embodiment, the support mounting member includes a first support portion and a second support portion. The first support portion is connected to the front subframe and is also connected to the cooling module. The second support portion is connected to the end of the first support portion away from the front subframe and is also connected to the front bumper.

[0009] In one embodiment, the cooling module is positioned above the first support portion.

[0010] In one embodiment, the bottom of the cooling module is provided with a positioning structure, and the first support portion is provided with a first positioning hole, into which the positioning structure is inserted.

[0011] In one embodiment, the edge of the first positioning hole is provided with a downwardly folded flange, and the flange is interference-fitted with the positioning structure;

[0012] And / or, the positioning structure is configured as a shock absorber.

[0013] In one embodiment, the front bumper has a connecting protrusion protruding toward the front subframe, the connecting protrusion being connected to the lower part of the second support by a fastening structure.

[0014] In one embodiment, the second support portion has a second positioning hole, and a nut is fixed on the side opposite to the connecting protrusion. The connecting protrusion has a connecting hole that mates with the second positioning hole, and a screw passes through the connecting hole and the second positioning hole and is threadedly connected to the nut.

[0015] And / or, the second support portion tapers away from the front subframe.

[0016] In one embodiment, the support mounting member further includes two folded portions disposed on opposite sides of the first support portion, the free ends of the folded portions extending downward;

[0017] And / or, the lower edge of the folded portion of the support mounting member gradually approaches the first support portion in a direction away from the front subframe;

[0018] And / or, in the left-right direction of the front subframe, there are two support mounts spaced apart.

[0019] In one embodiment, the front subframe includes a rear crossbeam arranged side-by-side with the front crossbeam, and a left longitudinal beam and a right longitudinal beam connecting the front crossbeam and the rear crossbeam, wherein the support mounting member is welded to the side of the front crossbeam opposite to the rear crossbeam.

[0020] This utility model also proposes a vehicle that includes the chassis described above.

[0021] In the technical solution of this utility model, while meeting the clearance requirements between the front bumper and the cooling module, the front bumper and the cooling module are mounted on the front side of the front crossbeam through a support mounting component. This not only minimizes the space occupied by the front bumper and the cooling module, allowing for a more reasonable design of the front overhang length and wheelbase, thus improving the vehicle's interior space, but also reduces the number of parts, lightens the overall vehicle weight, and lowers costs, and facilitates an increase in the vehicle's driving range, compared to the former where the front bumper and the cooling module are connected to the front subframe through their own connection structures.

[0041] To meet the needs of customers with larger vehicle spaces, it is necessary to rationally design the front overhang length, rear overhang length, and wheelbase. That is, to increase interior space with a shorter front / rear overhang and a longer wheelbase. However, a shorter front overhang will lead to a reduction in space. Consequently, when arranging the same functional modules, the arrangement space between each functional module will inevitably become more compact. Furthermore, since each functional module requires a corresponding mounting bracket for its arrangement, it is not conducive to meeting the clearance requirements between functional modules, nor is it conducive to reducing the overall vehicle weight.

[0042] To solve this technical problem, this utility model proposes a chassis that can be applied to vehicles, specifically electric vehicles and other vehicles that require a large interior space.

[0043] Please see Figures 1 to 9In one embodiment of this utility model, the chassis includes a front subframe 10, a support mounting member 20, and a cooling module 40. The front subframe 10 includes a front crossbeam 11. The support mounting member 20 is connected to the front side of the front crossbeam 11 and is used to mount the front bumper 30. The cooling module 40 is mounted on the support mounting member 20. In this way, the clearance requirements between the front bumper 30 and the cooling module 40 are reliably met, while the overall vehicle weight is reduced. As a result, the vehicle has a shorter front / rear overhang and a longer wheelbase, thereby increasing its interior space and improving the vehicle's ride comfort.

[0044] In the technical solution of this utility model, while meeting the gap requirements between the front bumper 30 and the cooling module 40, the front bumper 30 and the cooling module 40 are mounted on the front side of the front crossbeam 11 through the support mounting part 20. This not only reduces the space occupied by the front bumper 30 and the cooling module 40, allowing for a reasonable design of the front overhang length and wheelbase, and improving the vehicle's interior space, but also reduces the number of parts, lightens the overall vehicle weight, and lowers costs, as the front bumper 30 and the cooling module 40 share the support mounting part 20 for assembly on the front crossbeam 11. Compared to the front bumper 30 and the cooling module 40 being connected to the front subframe 10 through their respective connection structures, this also facilitates an increase in the vehicle's driving range.

[0045] It should be noted that the front overhang refers to the distance from the frontmost part of the vehicle to the front axle axis, the rear overhang refers to the distance from the rearmost part of the vehicle to the rear axle axis, and the wheelbase refers to the distance between the front and rear axle axes. The sum of these three distances is the total length of the vehicle. The front-to-rear direction of the vehicle is the direction from the front of the vehicle to the rear of the vehicle.

[0046] Please see Figure 4 In an embodiment of this utility model, the front subframe 10 includes a rear crossbeam 12 arranged parallel to the front crossbeam 11, and a left longitudinal beam 13 and a right longitudinal beam 14 connecting the front crossbeam 11 and the rear crossbeam 12. The support mounting member 20 is welded to the side of the front crossbeam 11 away from the rear crossbeam 12. It can be understood that the front subframe 10 is a full-frame frame, which helps to improve the overall strength of the front subframe 10. The support mounting member 20 is fixed to the side of the front crossbeam 11 away from the rear crossbeam 12 by welding, which can improve the connection strength between the support mounting member 20 and the front subframe 10 and ensure the assembly stability of the front bumper 30 and the cooling module 40 on the front subframe 10. Furthermore, since the support mounting member 20 protrudes from the front side of the front crossbeam 11 and extends towards the front bumper 30, it facilitates the connection between the front bumper 30 and the support mounting member 20. However, in other embodiments, the connection between the support mounting member 20 and the front crossbeam 11 is not limited to welding; the front subframe 10 only includes the front crossbeam 11, the left longitudinal beam 13 and the right longitudinal beam 14.

[0047] In this embodiment, two support mounting members 20 are spaced apart in the left-right direction of the front subframe 10, thus increasing the support points for the front bumper 30 and cooling module 40. This effectively improves the assembly stability and connection reliability of the front bumper 30 and cooling module 40 on the front subframe 10. Simultaneously, it reasonably distributes the forces generated by the front bumper 30 and cooling module 40 to the front crossbeam 11, allowing the front subframe 10 to further participate in supporting the front bumper 30 and cooling module 40, improving the support and force transmission effect of the support mounting members 20, and helping to extend the service life of the support mounting members 20. However, in other embodiments, only one support mounting member 20 is provided, or two or more support mounting members 20 are provided. The left-right direction of the front subframe 10 is the parallel direction of the left longitudinal beam 13 and right longitudinal beam 14, and the up-down direction of the support mounting members 20 is from the roof to the bottom of the vehicle.

[0048] Please see Figures 2 to 3 In an embodiment of this utility model, the support mounting component 20 includes a first support portion 21 and a second support portion 22. The first support portion 21 is connected to the front subframe 10 and is also connected to the cooling module 40. The second support portion 22 is connected to the end of the first support portion 21 away from the front subframe 10 and is also connected to the front bumper 30. This arrangement allows for a reasonable layout of the cooling module 40 and the front bumper 30, ensuring that the cooling module 40 is located behind the front bumper 30, thus guaranteeing the cooling effect of the cooling module 40 on the engine and the protective function of the front bumper 30 for the vehicle. The support mounting component 20 is an integral structural component, ensuring that it has good structural strength and rigidity, and reliably supports and connects the front bumper 30 and the cooling module 40, which helps to extend the service life of the support mounting component 20. The connection methods between the first support portion 21 and the front crossbeam 11 include, but are not limited to, welding, bonding, snap-fitting, and screw connection.

[0049] Optionally, in an embodiment of this utility model, the cooling module 40 is positioned above the first support portion 21. It is understood that the bottom of the cooling module 40 is connected to the first support portion 21, and the first support portion 21 reliably supports the cooling module 40. The top of the cooling module 40 can be fixed to the vehicle body by screws or other connecting structures, thereby improving the assembly stability of the cooling module 40 in the vehicle. In this process, the support mounting part 20 can assist in supporting the cooling module 40 before assembly, improving the connection efficiency and convenience between the cooling module 40 and the vehicle body. After assembly, it disperses the force generated by the cooling module 40, ensuring the stable assembly of the cooling module 40, and also helps to extend the service life of the support mounting part 20.

[0050] Specifically, in an embodiment of this utility model, the bottom of the cooling module 40 is provided with a positioning structure 41, and the first support portion 21 is provided with a first positioning hole 211. The positioning structure 41 is inserted into the first positioning hole 211. Thus, by inserting at least part of the positioning structure 41 into the first positioning hole 211, the cooling module 40 is supported and positioned above the first support portion 21, accelerating the assembly of the cooling module 40 on the front subframe 10. In addition, the edge of the first positioning hole 211 can abut against the cooling module 40 and / or the remaining part of the positioning structure 41, thereby increasing the effective contact area between the cooling module 40 and the support mounting member 20, and improving the support effect of the support mounting member 20 on the cooling module 40. The first positioning hole 211 can be directly formed on the first support portion 21, or the first support portion 21 can have an upwardly extending protrusion, and the first positioning hole 211 can be formed on this protrusion. However, in other embodiments, the positioning structure 41 is configured as a positioning hole, and the first support portion 21 has a positioning protrusion for inserting into the positioning hole.

[0051] Furthermore, in a further embodiment of this utility model, the edge of the first positioning hole 211 is provided with a downwardly folded flange 23, and the flange 23 is interference-fitted with the positioning structure 41; wherein, the flange 23 can extend along the edge of the first positioning hole 211 and form an annular flange 23. After the positioning structure 41 is inserted into the first positioning hole 211, the inner surface of the flange 23 is tightly fitted with the outer surface of the positioning structure 41, increasing the effective contact area, reducing the possibility of the positioning structure 41 coming out of the first positioning hole 211, and improving the positioning reliability between the positioning structure 41 and the first support part 21. However, in other embodiments, multiple flanges 23 are arranged at intervals along the circumference of the first positioning hole 211.

[0052] Optionally, in an embodiment of this utility model, the positioning structure 41 is configured as a shock absorber. The positioning structure 41 can be made of elastic materials such as rubber or silicone. Furthermore, the elastic deformation of the positioning structure 41 absorbs the impact force transmitted from the front subframe 10 and / or the front bumper 30 to the support mounting member 20, reducing vibrations transmitted to the vehicle body and improving the vehicle's driving stability and comfort. The elasticity of the positioning structure 41 also helps to achieve an interference fit between the positioning structure 41 and the flange 23.

[0053] Please see Figures 8 to 9 In an embodiment of this utility model, the front bumper 30 has a connecting protrusion 31 protruding toward the front subframe 10. The connecting protrusion 31 is connected to the lower part of the second support 22 by a fastening structure, thereby realizing the assembly of the front bumper 30 on the support mounting part 20. At the same time, it effectively reduces the risk of interference between the connecting protrusion 31 and the cooling module 40.

[0054] Specifically, in an embodiment of this utility model, the second support portion 22 has a second positioning hole 221, and a nut 51 is fixed on the side opposite to the connecting protrusion 31. The connecting protrusion 31 has a connecting hole 311 that mates with the second positioning hole 221. A screw 52 passes through the connecting hole 311 and the second positioning hole 221 and is threadedly connected to the nut 51. It can be understood that the nut 51 is pre-welded to the side of the second support portion 22 opposite to the connecting protrusion 31, that is, the nut 51 is located above the second support portion 22, and the threaded hole of the nut 51 is aligned with the second positioning hole 221. The connecting protrusion 31 is fitted to the lower surface of the second support portion 22, and the connecting hole 311 of the connecting protrusion 31 is aligned with the second positioning hole 221. The screw 52 passes through the connecting hole 311 and the second positioning hole 221 in sequence and is threadedly connected to the nut 51. However, in other embodiments, the fastening structure can also be a fastener provided on the connecting protrusion 31, which can be engaged in the second positioning hole 221.

[0055] Furthermore, while ensuring the connecting function of the second support part 22, the second support part 22 gradually tapers away from the front subframe 10, which can effectively reduce the material usage and weight of the support mounting part 20 and reduce costs.

[0056] Please see Figure 3 In an embodiment of this utility model, the support mounting member 20 further includes two folded portions 24 disposed on opposite sides of the first support portion 21. The free ends of the folded portions 24 extend downward, which can enhance the overall stability of the support mounting member 20 by increasing the local stiffness at the first support portion 21, thereby improving the load-bearing effect of the support mounting member 20 on the front bumper 30 and the cooling module 40. It can also reduce the possibility of interference between the folded portions 24 and the connecting protrusion 31, and ensure the close connection between the connecting protrusion 31 and the second support portion 22.

[0057] Wherein, the lower edge of the folded portion 24 of the support mounting member 20 gradually approaches the first support portion 21 in a direction away from the front subframe 10. This can optimize the stress distribution on the support mounting member 20, reduce excessive deformation or damage to the support mounting member 20 during the stress process, and / or reduce stress concentration at the connection between the first support portion 21 and the front crossbeam 11, such as at the weld, thereby reducing the risk of weld failure.

[0058] Optionally, in an embodiment of the present invention, the support mounting member 20 is further provided with an opening 212 located between the first positioning hole 211 and the front subframe 10. The opening 212 helps to enhance the strength and rigidity of the first support part 21 to a certain extent, while reducing the weight of the support mounting member 20.

[0059] This utility model also proposes a vehicle, which includes a chassis. The specific structure of the chassis is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
