Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a front assembly of a vehicle and the vehicle itself. Background Technology

[0002] Currently, according to the requirements of hybrid vehicles, the entire vehicle needs to be designed with both electric drive and fuel systems under the chassis, which directly increases the difficulty of the overall chassis layout. How to achieve the layout compatibility of the electric drive system and the fuel drive system brings many challenges and design requirements.

[0003] In the existing chassis layout of mass-produced hybrid vehicles, the hybrid drive assembly is located in front of the front subframe, and the muffler is located behind the rear electric drive assembly. The exhaust pipe connecting the hybrid drive assembly and the muffler starts from the front subframe, passes directly through the chassis, then goes around the left or right side of the battery, then around the fuel tank, across the rear axle and the rear electric drive assembly, and then connects to the muffler. Finally, the exhaust gas is guided out through the exhaust tailpipe.

[0004] From the perspective of the overall layout structure, since the exhaust pipe passes through the entire chassis, the left or right side of the battery must provide a passage to avoid the exhaust pipe. As a result, it is impossible to completely cover the left or right side of the chassis with the battery. Furthermore, due to the interference of the muffler system, it is impossible to completely separate the hybrid drive system. Consequently, the performance requirements of the fuel drive system and the pure electric drive system cannot be maximized. Utility Model Content

[0005] One objective of this utility model is to provide a front assembly for a vehicle to solve the problem in the prior art where the exhaust pipe passes through the entire chassis and affects the battery arrangement; the second objective is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A front assembly of a vehicle includes: a front hybrid drive assembly including an engine having an exhaust port; a cooling assembly including a radiator disposed at the front radiator of the front hybrid drive assembly for cooling the engine; and an exhaust assembly including a muffler having a muffler inlet communicating with the exhaust port, the muffler being disposed at the front of the front hybrid drive assembly and below the radiator.

[0008] Based on the aforementioned technical means, the muffler of the exhaust assembly is directly arranged in front of the front hybrid drive assembly and below the radiator. The exhaust pipe connecting the muffler and the engine exhaust port does not need to run through the entire chassis, thus minimizing the impact of the muffler on the chassis. Furthermore, there is no need to set up clearance passages on the left and right sides of the battery. The front end and left and right sides of the battery remain the same as those of the pure electric vehicle, providing more complete space for the battery to meet the control requirements for increasing battery capacity. It also avoids the risk of heat damage caused by the exhaust pipe under the chassis of existing hybrid vehicles bypassing the battery and fuel tank. It also achieves better oil-electric separation, reduces the disturbance of the muffler to the rear axle and rear drive system, and thus reduces the mutual interference between the two systems.

[0009] Furthermore, the projection area of ​​the muffler in the horizontal plane overlaps with the projection area of ​​the radiator in the horizontal plane. The area of ​​the overlapping area of ​​the radiator and the muffler in the horizontal plane is S1, the area of ​​the projection area of ​​the muffler is S2, and the area of ​​the projection area of ​​the radiator in the horizontal plane is S3, where S1 / S2 > S3×1%.

[0010] Based on the above technical means, by designing the muffler and radiator to overlap in the horizontal plane, the engine compartment structure and engine are minimized, thereby minimizing the impact on the overall vehicle structure.

[0011] Furthermore, the muffler has a muffler outlet, and the exhaust assembly also includes an exhaust tailpipe, one end of which is connected to the muffler outlet, and the other end of which is the exhaust tail port.

[0012] Based on the above technical means, the exhaust gas discharged from the engine exhaust port is effectively absorbed and reflected by the muffler, which significantly reduces the noise when the engine exhaust gas is discharged. The exhaust tailpipe further guides the flow of exhaust gas, which helps to optimize the flow path of exhaust gas and reduce the resistance encountered when exhaust gas is discharged, thereby improving the efficiency and power output of the engine.

[0013] Furthermore, there are two muffler outlets and two exhaust tailpipes, with each exhaust tailpipe corresponding to one of the two muffler outlets; one exhaust tailpipe is located on the left side of the muffler and the other exhaust tailpipe is located on the right side of the muffler; or, both exhaust tailpipes are located on the left side of the muffler; or, both exhaust tailpipes are located on the right side of the muffler.

[0014] Based on the aforementioned technical methods, using dual exhaust tailpipes can more effectively expel exhaust gases and reduce back pressure in the system. This helps improve engine efficiency and power output. Furthermore, by dispersing the exhaust gas flow path, the airflow density within a single pipe can be reduced, thereby improving overall exhaust efficiency and further enhancing engine performance. Two exhaust tailpipes can also help distribute noise more evenly, avoiding the noise concentration problem caused by exhaust from one side.

[0015] Furthermore, both a muffler outlet and an exhaust tailpipe are provided, with the exhaust tailpipe located on the left or right side of the muffler.

[0016] Based on the above-mentioned technical means, the use of a single exhaust tailpipe reduces material usage and production complexity, thereby reducing manufacturing costs. Furthermore, the elimination of an exhaust tailpipe and related components (such as connectors and brackets) helps to reduce the overall vehicle weight, which has a positive impact on improving fuel economy and performance.

[0017] Furthermore, the front assembly also includes a front axle and two front wheels, with the two front wheels corresponding to the two ends of the front axle, and the exhaust outlet located in front of the front axle.

[0018] Based on the above technical means, the exhaust tailpipe does not occupy the space behind the front axle, avoiding the exhaust tailpipe extending to the rear of the front axle and occupying the space in front of the battery, thus optimizing space utilization.

[0019] Furthermore, the exhaust outlet is located between the two front wheels, or the exhaust outlet is located on the outside of the front wheels.

[0020] Based on the aforementioned technical methods, the exhaust tailpipe is not directly exposed on the outside, which helps reduce damage to the tailpipe and the side of the vehicle body from external factors (such as mud, water, stones, etc.). The exhaust tailpipe is located on the side of the vehicle, facilitating its installation and simplifying subsequent maintenance.

[0021] Furthermore, the front assembly includes a front engine compartment, with the engine and radiator located inside the front engine compartment and the muffler located outside the front engine compartment.

[0022] Based on the aforementioned technical methods, with the engine and radiator located inside the front engine compartment, the airflow can be guided through the radiator using the front air intake grille, thereby more effectively reducing the engine's operating temperature. The radiator's proximity to the engine also helps shorten the coolant circulation path, improving the cooling system's response speed. Furthermore, as core powertrain components of the vehicle, the engine and radiator receive better physical protection within the front engine compartment, preventing damage from collisions or other external factors. Placing the muffler outside the front engine compartment, away from high-temperature sensitive components such as the engine and electronic equipment, reduces the risk of thermal interference and helps protect these components from overheating. Moreover, the muffler generates high-temperature exhaust gases during operation; placing it outside the front engine compartment prevents direct contact between the high temperatures and flammable liquids or materials within the compartment, reducing the potential fire risk.

[0023] A vehicle including the aforementioned front assembly.

[0024] Furthermore, the vehicle also includes a chassis, with the muffler of the front assembly located below the chassis and the radiator located above the chassis.

[0025] Based on the aforementioned technical methods, placing the muffler under the chassis frees up space in the front engine compartment, allowing for a more rational arrangement of the engine, transmission, battery pack, and electronic control system. It also avoids thermal interference or physical interference with the radiator or other high-temperature sensitive components. Since the muffler generates a significant amount of heat during operation, placing it under the chassis, away from the radiator and other electronic equipment, effectively reduces the adverse effects of heat radiation on the cooling and electrical systems. Placing the radiator above the chassis allows for better reception of oncoming airflow, improving cooling efficiency, especially at high speeds.

[0026] The beneficial effects of this utility model are:

[0027] Moving the muffler of the exhaust assembly to the front of the vehicle, directly at the very front of the hybrid drive assembly, minimizes the muffler's impact on the battery. The left and right sides and front of the battery can be arranged in the same layout as the pure electric vehicle. The chassis structure of the hybrid and pure electric vehicles is interchangeable, allowing them to be produced on the same production line. This enables a single production line to support the production of multiple models, reducing costs and improving production flexibility and efficiency. The muffler is also located below the radiator. Through the overlapping arrangement of the muffler and radiator's projection surfaces on the chassis, minimal disturbance to the engine compartment structure and engine is achieved. This fundamentally solves the problem of the exhaust pipe and front muffler affecting the front and left and right sides of the battery. Furthermore, it allows for front-mounted muffler placement without altering the existing engine compartment layout or engine structure. Attached Figure Description

[0033] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0035] This embodiment proposes a front assembly for a vehicle, which is part of the vehicle, such as... Figures 1-4 As shown, the front assembly includes: a front hybrid drive assembly 1, a cooling assembly, and an exhaust assembly 3. The front hybrid drive assembly 1 includes an engine with an exhaust port; the cooling assembly includes a radiator 201, which is located in front of the front hybrid drive assembly 1 and is used to cool the engine; the exhaust assembly 3 includes a muffler 301 with a muffler inlet that communicates with the exhaust port, and is located in front of the front hybrid drive assembly 1 and below the radiator 201.

[0036] Using the technical solution of this embodiment, the muffler 301 of the exhaust assembly 3 is directly arranged in front of the front hybrid drive assembly 1 and below the radiator 201. The exhaust pipe connecting the muffler 301 and the exhaust port of the engine does not need to run through the entire chassis, thus minimizing the impact of the muffler 301 on the chassis. Furthermore, there is no need to set up clearance passages on the left and right sides of the battery 6. The front end and left and right sides of the battery 6 remain the same as those of the pure electric vehicle, providing more complete space for the battery 6 to meet the control requirements for increasing the capacity of the battery 6. It also avoids the risk of heat damage caused by the exhaust pipe under the chassis of the existing hybrid vehicle bypassing the battery 6 and the fuel tank 8. It also achieves better oil-electric separation, reduces the disturbance of the muffler 301 to the rear axle 9 and the rear drive system, and thus reduces the mutual interference between the two systems.

[0037] Furthermore, the muffler 301 is positioned in front of the engine, which not only resolves the conflict between the muffler 301 and the battery 6 and reduces the impact of the muffler 301 on the fuel tank 8, but also frees up the chassis space behind the rear axle 9, the rear electric drive assembly 10 and the rear wheels 11, thereby increasing the vehicle's trunk space and providing users with more usable storage areas.

[0038] In this embodiment, as Figures 1 to 3 As shown, the projection area of ​​the muffler 301 in the horizontal plane overlaps with the projection area of ​​the radiator 201 in the horizontal plane. The area of ​​the overlapping area of ​​the radiator 201 and the muffler 301 in the horizontal plane is S1, the area of ​​the projection area of ​​the muffler 301 is S2, and the area of ​​the projection area of ​​the radiator 201 in the horizontal plane is S3, where S1 / S2 > S3 × 1%. By arranging the muffler 301 and the radiator 201 in an overlapping manner in the horizontal plane, minimal disturbance to the engine compartment structure and the engine is achieved, thereby minimizing the impact on the overall vehicle structure.

[0039] Furthermore, if 1% of the area of ​​S3 is very small, and S1 / S2 is less than or equal to S3×1%, it means that the radiator 201 and the muffler 301 do not overlap. This requires lengthening the engine compartment, which leads to an increase in the overall length of the vehicle or engine, increases the amount of material used and structural weight, and may also affect the layout of the cab and trunk, thereby affecting the chassis layout.

[0040] Therefore, by controlling S1 / S2 > S3×1%, the length of the engine compartment can be effectively shortened, which helps the whole vehicle to be more compact. It can also reduce the amount of materials used in structural components, brackets, and housings, which helps to reduce the weight of the whole vehicle. This, in turn, is conducive to vehicle lightweighting, space optimization, platform uniformity, and manufacturing cost control.

[0041] In this embodiment, as Figures 1 to 3 As shown, the muffler 301 has a muffler outlet, and the exhaust assembly 3 also includes an exhaust tailpipe 302. One end of the exhaust tailpipe 302 is connected to the muffler outlet, and the other end of the exhaust tailpipe 302 is the exhaust outlet. The exhaust gas discharged from the engine's exhaust port is effectively absorbed and reflected by the muffler 301, significantly reducing the noise when the engine exhaust gas is discharged. The exhaust tailpipe 302 further guides the exhaust gas flow, helping to optimize the exhaust gas flow path and reduce the resistance encountered when the exhaust gas is discharged, thereby improving the engine's efficiency and power output.

[0042] In this embodiment, as Figures 1 to 3As shown, there are two muffler outlets and two exhaust tailpipes 302, each corresponding to one of the two muffler outlets. One exhaust tailpipe 302 is located on the left side of the muffler 301, and the other exhaust tailpipe 302 is located on the right side of the muffler 301. Using dual exhaust tailpipes 302 allows for more efficient exhaust gas discharge and reduces back pressure in the system. This helps improve engine efficiency and power output. Furthermore, by dispersing the exhaust gas flow path, the airflow density within a single pipe can be reduced, thereby improving overall exhaust efficiency and further enhancing engine performance. The two exhaust tailpipes 302 also help distribute noise more evenly, avoiding noise concentration problems caused by exhaust from one side.

[0043] It is understood that in other embodiments, the two exhaust tailpipes 302 are located on the left side of the muffler 301, or on the right side of the muffler 301. The concentration of the two exhaust tailpipes 302 on the same side of the vehicle may simplify the layout design of the entire exhaust system, reduce the arrangement of pipes in different directions, and help reduce the complexity and cost in the production process.

[0044] It is understood that in other embodiments, both a muffler outlet and an exhaust tailpipe 302 are provided, with the exhaust tailpipe 302 located on the left or right side of the muffler 301. In this case, a single exhaust tailpipe 302 is used. The single exhaust tailpipe 302 reduces material usage and production complexity, thereby reducing manufacturing costs. Furthermore, reducing one exhaust tailpipe 302 and related components (such as connectors, brackets, etc.) helps to reduce the overall vehicle weight, which has a positive impact on improving fuel economy and performance.

[0045] In this embodiment, as Figures 1 to 3 As shown, the front assembly also includes a front axle and two front wheels 4. The two front wheels 4 are arranged one-to-one with the two ends of the front axle. The exhaust tailpipe is located in front of the front axle. The exhaust tailpipe 302 does not occupy the space behind the front axle, thus avoiding the exhaust tailpipe 302 extending to the rear of the front axle and occupying the front space of the battery 6, thereby optimizing the space utilization.

[0046] Furthermore, the muffler 301 is located entirely in front of the front wheel 4, and the exhaust tailpipe 302 does not cross the front wheel 4, which can provide more installation space for the battery 6 and improve the utilization of interior space.

[0047] In this embodiment, as Figures 1 to 3 As shown, the exhaust outlet is located between the two front wheels 4. The exhaust outlet is not directly exposed on the outside, which helps to reduce the damage to the tailpipe and the side of the vehicle body caused by external factors (such as mud, water, stones, etc.). The exhaust outlet can avoid the air intake of the vehicle's air conditioning system, which helps to avoid the air intake path of the passenger compartment, reduce the amount of exhaust gas entering the passenger compartment, ensure the air quality of the passenger compartment, and improve the safety performance of the vehicle.

[0048] It is understood that in other embodiments, such as Figure 4 As shown, the exhaust tail outlet is located on the outside of the front wheel 4, and the exhaust tailpipe 302 is located on the side of the vehicle, which facilitates the installation of the exhaust tailpipe 302 and makes subsequent maintenance and repair more convenient.

[0049] In this embodiment, the front assembly includes a front engine compartment, with the engine and radiator 201 located inside the front engine compartment, and the muffler 301 located outside the front engine compartment. The engine and radiator 201 being located inside the front engine compartment allows the front air intake grille to guide airflow over the radiator 201, thereby more effectively reducing the engine's operating temperature. The proximity of the radiator 201 to the engine also helps shorten the coolant circulation path, improving the cooling system's response speed. Furthermore, as core powertrain components of the vehicle, placing the engine and radiator 201 inside the front engine compartment provides better physical protection against damage from collisions or other external factors. Placing the muffler 301 outside the front engine compartment, away from high-temperature sensitive components such as the engine and electronic equipment, reduces the risk of thermal interference and helps protect these components from overheating. Additionally, the muffler 301 generates high-temperature exhaust gases during operation; placing it outside the front engine compartment prevents direct contact between high temperatures and flammable liquids or materials inside the compartment, reducing the potential fire risk.

[0050] In this embodiment, the exhaust assembly 3 also includes an exhaust pipe connecting the exhaust port and the muffler inlet. As part of the exhaust assembly 3, the exhaust pipe helps to exhaust high-temperature exhaust gases from the engine area and disperse them to other parts of the vehicle, preventing localized overheating and protecting surrounding components from damage. The effective combination of the exhaust pipe and the muffler 301 can significantly reduce exhaust noise by absorbing and reflecting sound waves. The reasonably arranged pipe length and diameter also affect the sound frequency, helping to further tune noise characteristics and provide a quieter driving experience.

[0051] It should be noted that the front hybrid drive assembly 1, muffler 301, radiator 201, etc. can be selected and applied based on the existing structure, or they can be optimized or redesigned according to the actual situation of vehicle space, performance, cost, etc., so as to meet the needs of different models, different power systems or different users.

[0052] This embodiment also proposes a vehicle including the aforementioned front assembly.

[0053] In this embodiment, the vehicle also includes a chassis. The muffler 301 of the front assembly is located below the chassis, and the radiator 201 is located above the chassis. Placing the muffler 301 below the chassis frees up space in the front engine compartment, allowing for a more rational arrangement of the engine, transmission, battery pack, electronic control system, etc., and preventing thermal interference or physical interference with the radiator 201 or other high-temperature sensitive components. The muffler 301 generates a significant amount of heat during operation; placing it below the chassis, away from the radiator 201 and other electronic equipment, effectively reduces the adverse effects of heat radiation on the cooling and electrical systems. Placing the radiator 201 above the chassis allows for better reception of oncoming airflow, improving cooling efficiency, especially at high speeds.

[0054] In this embodiment, the muffler 301 of the exhaust assembly 3 is moved forward to the front of the vehicle, directly positioned at the very front of the hybrid drive assembly 1, minimizing the impact of the muffler 301 on the battery 6. The left and right sides and front of the battery 6 can be arranged in the same layout as in a pure electric vehicle. The muffler 301 is also located below the radiator 201. Through the overlapping arrangement of the muffler 301 and the radiator 201 on the chassis projection surface, minimal disturbance to the engine compartment structure and the engine is achieved. This fundamentally solves the problem of the exhaust pipe and the front muffler 301 affecting the front of the battery 6 and the left and right sides of the battery 6. At the same time, it also solves the problem of achieving the front placement of the muffler 301 without changing the existing engine compartment structure layout and engine structure.

[0055] Furthermore, the muffler 301 and exhaust tailpipe 302 are positioned under the chassis near the front engine compartment. When arranging the exhaust tailpipe 302, it can be placed directly on either the left or right side of the vehicle, or on one side, depending on the requirements. Depending on the relative relationship between the exhaust tailpipe 302 and the front wheels 4, it can be placed inside the two front wheels 4, or outside. The specific arrangement of the exhaust tailpipe 302 needs to be designed based on the vehicle model, styling, and requirements.

[0056] Furthermore, the muffler 301 includes a muffler body and a muffler component. The axis of the muffler body extends along the left and right directions of the vehicle, and muffler outlets are provided on the left and right sides of the muffler body.

[0057] Furthermore, the vehicle also includes a chassis, which comprises a front subframe assembly 7. The front subframe assembly 7 includes a front subframe body 701 and a load-bearing beam assembly 702. The front subframe body 701 includes a front crossbeam 7011, a front left longitudinal beam 7012, and a front right longitudinal beam 7013. It is understandable that the front subframe assembly 7 can be selected and applied based on existing structures, or it can be optimized or redesigned according to the actual situation of vehicle space, performance, cost, etc., to meet the needs of different vehicle models, different powertrains, or different users.

[0058] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
