Description

Technical Field

[0001] The present application relates to the technical field related to new energy vehicles, and in particular to a front subframe structure. Background Art

[0002] With the continuous development of new energy vehicles and the diversity of market demand, more and more car companies are adopting a dual-energy strategy, that is, pure electric vehicles and extended-range vehicles are developed simultaneously on the same platform. There are differences in the performance development of pure electric vehicles and extended-range vehicles. Pure electric vehicles have larger battery packs and are developed according to the maximum layout. In order to fully protect the battery pack and pedestrians, pure electric vehicles are generally developed according to five-star safety requirements; extended-range vehicles have smaller battery packs, and the models are generally developed according to national standards.

[0003] The front subframe is an important component of the automobile chassis parts system, which is mainly used to connect the body, engine mount, suspension and other parts. At present, the front subframe of pure electric vehicles and the front subframe of extended-range vehicles need to be produced separately, which has a high production cost. Utility Model Content

[0004] In view of this, it is necessary to provide a front subframe structure that can solve the above technical problems.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A front subframe structure is applied to a pure electric vehicle or a range-extended vehicle, wherein the front subframe structure comprises a front frame assembly, a rear frame assembly and a suspension bracket, wherein the front frame assembly and the rear frame assembly are both arranged as an integrated structure;

[0007] When the front subframe structure is applied to the pure electric vehicle, the front frame assembly and the rear frame assembly are connected and are used together to carry the motor of the pure electric vehicle;

[0008] When the front subframe structure is applied to the range-extended vehicle, the frame rear assembly is connected to the suspension bracket and is used together to support the engine of the range-extended vehicle.

[0009] It can be understood that through the above-mentioned structural setting, when the front subframe structure is applied, the assembly of the front frame assembly and the rear frame assembly can be applied to pure electric vehicles, and the assembly of the rear frame assembly and the suspension bracket can be applied to extended-range vehicles, so that the front subframe structure can be adapted to both pure electric vehicles and extended-range vehicles, the front frame assembly and the rear frame assembly can be produced and prepared separately using molds, and the parts of the front subframe structure can be partially shared, and the production cost is relatively low; at the same time, since the front frame assembly and the rear frame assembly are both arranged as an integrated structure, the front frame assembly and the rear frame assembly can be prepared as a whole using corresponding molds during production, thereby reducing the production cost.

[0010] In one embodiment, a first longitudinal beam is formed on the front assembly of the frame, and a second longitudinal beam is formed on the rear assembly of the frame, and the first longitudinal beam can be plugged and matched with the second longitudinal beam;

[0011] Furthermore, the first longitudinal beam is connected to the second longitudinal beam.

[0012] It can be understood that the assembly of the front frame assembly on the rear frame assembly is specifically realized by plugging and fitting the first longitudinal beam on the front frame assembly with the second longitudinal beam on the rear frame assembly, so that the assembly connection between the front frame assembly and the rear frame assembly can be facilitated.

[0013] In one embodiment, the first longitudinal beam and the second longitudinal beam are plug-fitted to form a calf beam, and the front frame assembly and the rear frame assembly are transmission-connected via the calf beam.

[0014] It can be understood that by plugging and matching the first longitudinal beam and the second longitudinal beam to form the calf beam, the calf beam, the first longitudinal beam on the front frame assembly and the second longitudinal beam on the rear frame assembly can form a complete force transmission path, so that when the front frame assembly and the rear frame assembly are connected, the overall force balance can be effectively improved and the collision performance can be enhanced.

[0015] In one embodiment, the first longitudinal beam and the second longitudinal beam are connected by welding;

[0016] And / or, the first longitudinal beam and the second longitudinal beam are connected by a first connecting member.

[0017] It can be understood that the first longitudinal beam and the second longitudinal beam are connected by welding, which is beneficial to improve the firmness of the connection between the front frame assembly and the rear frame assembly; and / or the first longitudinal beam and the second longitudinal beam are connected by a first connecting member, which can facilitate the disassembly and assembly between the front frame assembly and the rear frame assembly.

[0018] In one embodiment, the front subframe structure also includes an anti-collision beam. When the front subframe structure is applied to the pure electric vehicle, the anti-collision beam is arranged on a side of the frame front assembly away from the frame rear assembly and is connected to the frame front assembly.

[0019] It can be understood that the anti-collision beam and the rear frame assembly are respectively arranged on two opposite sides of the front frame assembly, so that the anti-collision beam can protect the whole formed by the connection of the front frame assembly and the rear frame assembly, thereby improving the safety of the pure electric vehicle using the front subframe structure.

[0020] In one embodiment, the anti-collision beam abuts against the front assembly of the vehicle frame, and the anti-collision beam and the front assembly of the vehicle frame are connected by a second connecting member.

[0021] It is understandable that the anti-collision beam is connected to the front assembly of the vehicle frame by using the second connecting member, so that the assembly of the anti-collision beam on the front assembly of the vehicle frame can be facilitated.

[0022] In one embodiment, a mounting plane is formed on the front assembly of the vehicle frame, and the anti-collision beam can be attached to the mounting plane;

[0023] Wherein, the second connecting member can pass through the anti-collision beam and the installation plane in sequence and be threadedly connected to the front assembly of the frame.

[0024] It can be understood that the front assembly of the frame uses a mounting plane for the anti-collision beam to abut against, which can increase the contact area between the anti-collision beam and the front assembly of the frame, and improve the stability when the anti-collision beam and the front assembly of the frame are connected; and the second connecting member passes through the anti-collision beam and the mounting plane and is connected to the front assembly of the frame in a threaded manner, so that the assembly of the anti-collision beam and the mounting plane on the front assembly of the frame can be facilitated.

[0025] In one of the embodiments, a mounting groove is provided on the rear assembly of the frame, and the suspension bracket is partially inserted into the mounting groove and welded to the rear assembly of the frame.

[0026] It can be understood that by opening a mounting groove on the rear assembly of the frame, the suspension bracket can be easily mounted in the mounting groove; and the suspension bracket mounted in the mounting groove is welded to the rear assembly of the frame, which is beneficial to improve the connection strength when the suspension bracket is connected to the rear assembly of the frame.

[0027] In one embodiment, the rear frame assembly is provided with a plug-in interface, and the rear frame assembly can be plugged and matched with the front frame assembly through the plug-in interface;

[0028] Among them, the front subframe structure also includes a sealing plate, which is arranged corresponding to the plug-in interface. When the front subframe structure is applied to an extended-range vehicle, the sealing plate is arranged at the position where the corresponding plug-in interface is located and is connected to the rear assembly of the frame to cover the corresponding plug-in interface.

[0029] It can be understood that the plug-in interface on the rear assembly of the frame is covered by a sealing plate. In this way, when the current subframe structure is applied to extended-range vehicles, the sealing plate can seal the plug-in interface on the rear assembly of the frame to prevent foreign matter from entering the cavity of the rear assembly of the frame from the plug-in interface.

[0030] In one of the embodiments, a mounting bracket is formed on the frame rear assembly, and the mounting bracket is used to support the compressor.

[0031] Due to the application of the above solution, the present application has the following advantages compared with the prior art:

[0032] The front subframe structure for which protection is sought in the present application, through the above-mentioned structural setting, when the front subframe structure is applied, the assembly of the front frame assembly and the rear frame assembly can be applied to pure electric vehicles, and the assembly of the rear frame assembly and the suspension bracket can be applied to extended-range vehicles, so that the front subframe structure can be adapted to both pure electric vehicles and extended-range vehicles, the front frame assembly and the rear frame assembly can be produced and prepared separately using molds, and some commonality of the front subframe structure parts can be achieved, and the production cost is low; at the same time, since the front frame assembly and the rear frame assembly are both arranged as an integrated structure, the front frame assembly and the rear frame assembly can be produced as a whole using corresponding molds, thereby reducing the production cost.

[0047] It should be noted that when the front subframe structure 100 of the present application is applied to a pure electric vehicle, the front frame assembly 10 and the rear frame assembly 20 are assembled; when the front subframe structure 100 is applied to an extended-range vehicle, the rear frame assembly 20 is assembled with the suspension bracket 30, and the front frame assembly 10 is cancelled. In this way, rapid assembly according to different vehicle models can be achieved, and the rear frame assembly 20 can be partially universal.

[0048] like Figure 2 , Figure 3 As shown, in one embodiment, a first longitudinal beam 11 is formed on the front frame assembly 10, and a second longitudinal beam 21 is formed on the rear frame assembly 20. The first longitudinal beam 11 can be plugged and matched with the second longitudinal beam 21; and the first longitudinal beam 11 is connected to the second longitudinal beam 21.

[0049] like Figure 2 , Figure 3 As shown, in one embodiment, the first longitudinal beam 11 and the second longitudinal beam 21 are plugged together to form a calf beam 120, and the front frame assembly 10 and the rear frame assembly 20 are connected in transmission through the calf beam 120. In other words, the first longitudinal beam 11 and the second longitudinal beam 21 are plugged together to form the calf beam 120, so that the calf beam 120, the first longitudinal beam 11 on the front frame assembly 10 and the second longitudinal beam 21 on the rear frame assembly 20 can form a complete force transmission path, so that when the front frame assembly 10 and the rear frame assembly 20 are connected, the overall force balance can be effectively improved, and the collision performance can be improved.

[0050] like Figure 2 , Figure 3 As shown, in one embodiment, the first longitudinal beam 11 and the second longitudinal beam 21 are connected by welding; and / or, the first longitudinal beam 11 and the second longitudinal beam 21 are connected by a first connecting member (not shown). In other words, by connecting the first longitudinal beam 11 and the second longitudinal beam 21 by welding, it is beneficial to improve the firmness of the connection between the front frame assembly 10 and the rear frame assembly 20; and / or, the first longitudinal beam 11 and the second longitudinal beam 21 are connected by a first connecting member, which can facilitate the disassembly and assembly between the front frame assembly 10 and the rear frame assembly 20. Here, the first connecting member can be a connecting member such as a bolt or a screw. Of course, for those skilled in the art, the first longitudinal beam 11 can also be clamped to the second longitudinal beam 21, which will not be elaborated here.

When the front subframe structure 100 is applied to a pure electric vehicle, the anti-collision beam 40 is arranged on a side of the frame front assembly 10 away from the frame rear assembly 20 and connected to the frame front assembly 10. In other words, the anti-collision beam 40 and the frame rear assembly 20 are respectively arranged on two opposite sides of the frame front assembly 10, so that the anti-collision beam 40 can protect the whole formed by the connection of the frame front assembly 10 and the frame rear assembly 20, thereby improving the safety of the pure electric vehicle using the front subframe structure 100.

[0053] like Figure 1 As shown, in one embodiment, the anti-collision beam 40 abuts against the front frame assembly 10, and the anti-collision beam 40 and the front frame assembly 10 are connected by a second connecting member 41. In other words, the anti-collision beam 40 and the front frame assembly 10 are connected by the second connecting member 41, so that the assembly connection of the anti-collision beam 40 on the front frame assembly 10 can be facilitated. Here, the second connecting member 41 can be a connecting member such as a bolt or a screw.

When the front sub-frame structure 100 is applied to an extended-range vehicle, the sealing plate 50 is arranged at the position where the corresponding plug-in interface 22 is located and is connected to the rear frame assembly 20, so as to cover the corresponding plug-in interface 22. In other words, the plug-in interface 22 on the rear frame assembly 20 is covered by the sealing plate 50, so that when the front sub-frame structure 100 is applied to an extended-range vehicle, the sealing plate 50 can seal the plug-in interface 22 on the rear frame assembly 20, and prevent foreign matter from entering the cavity of the rear frame assembly 20 from the plug-in interface 22.
