Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, the use of the azimuth terms "upper" and "lower" are defined based on the direction in which the relevant parts are actually used, for example: the upper surface of the second shell is provided with an avoidance groove for avoiding a crankshaft of the engine, wherein the upper surface refers to the surface of the second shell facing the engine body when the oil pan assembly is installed on the engine body; the lower surface of the second shell is provided with reinforcing ribs, wherein the lower surface refers to the surface of the second shell, which faces away from the engine body when the oil pan assembly is installed on the engine body; the oil storage chamber may be configured as a shell-like structure with an "upper side" opening, which means that the oil storage chamber is configured as a shell-like structure with an opening toward the engine body when the oil pan assembly is mounted on the engine body, i.e., the upper side here means the side close to the engine body.

In addition, in this disclosure, the terms "first," "second," etc. are used to distinguish one element from another without sequence or importance. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated.

Referring to fig. 1-3, in accordance with a first aspect of the present disclosure, an oil pan assembly is provided for mounting to an engine block, the oil pan assembly including a housing formed with a receptacle 200 to receive at least a portion of a muffler assembly.

The present disclosure is not limited to the specific structure of the case, and may include the first case 110 and the second case 210, which will be described below, or may add the third case 220 on the basis of the first case 110, the second case 210. The accommodation portion 200 may be an accommodation space formed inside the housing itself. Alternatively, the receiving part 200 may also be an open space formed by an external configuration of the case (e.g., surrounded by the first case 110 and the second case 210 or surrounded by the first case 110, the second case 210, and the third case 220, which will be mentioned later), to which the present disclosure is not limited, and specific structures of the case and the receiving part 200 will be described in detail later.

By using the above technical solution, the muffler assembly 420 is disposed in the accommodating portion 200, so that the integration level of components in the power cabin is high, the space utilization rate is high, and the space on the vehicle body for disposing the muffler assembly 420 is released. Second, compared to disposing the muffler assembly 420 at a position away from the engine (both at the front and rear ends of the vehicle, respectively), the tail pipe 430 does not need to extend from one end of the vehicle to the other end, shortening the length of the tail pipe 430, reducing the exhaust back pressure, improving the thermal efficiency of the engine, and being able to reduce the number of parts, and reducing the failure rate and cost of the whole vehicle. Further, if the muffler assembly 420 and the engine are integrated at the front end of the vehicle, the tail pipe 430 can complete the exhaust at the front end of the vehicle, and effectively "conceal" the exhaust (omitting the tail pipe at the rear side of the vehicle) in appearance, so that the hybrid vehicle tends to develop more electrically. Finally, when the oil pan assembly is used in a hybrid vehicle, the tail pipe 430 does not need to extend from one end of the vehicle to the other end via the chassis or the floor, so that a larger arrangement space can be reserved for the battery pack 500, which is beneficial to improving the cruising ability of the vehicle.

Referring to fig. 1, in an embodiment of the present disclosure, the housing may include a first housing 110 and a second housing 210, wherein the first housing 110 may be formed with an oil reservoir 100, and the oil reservoir 100 may be used to receive oil. The second housing 210 may be coupled to a side surface of the first housing 110 to enclose the receiving portion 200 with the first housing 110. The first housing 110 and the second housing 210 may form an included angle, for example, 90 °, 120 °, etc., so as to form the accommodating portion 200 at an included angle therebetween.

Referring to fig. 1, in the embodiment of the present disclosure, a bottom surface of the oil storage chamber 100 formed by the first housing 110 may be configured as a detachable cover 120, and an openable and closable oil drain port 121 may be provided on the cover 120. When the inside of the oil storage chamber 100 is required to be overhauled, the oil discharge port 121 is opened to discharge the engine oil in the oil storage chamber 100, and the cover 120 is detached. In the embodiment of the present disclosure, the cover 120 and the oil storage chamber 100 may be detachably connected through bolts and nuts, and in order to ensure that oil may not leak when the cover 120 is mounted on the oil storage chamber 100, a gasket may be interposed between the cover 120 and the oil storage chamber 100.

In order to measure the oil amount in the oil storage cavity 100 in real time and further obtain the oil amount in the engine, in the embodiment of the present disclosure, the oil pan assembly may further include an oil gauge 130 disposed in the oil storage cavity 100, and the present disclosure does not limit the type of the oil gauge 130, and may be an electronic oil gauge, or may also be an indication rod type oil gauge, etc.

In the embodiment shown in fig. 1, the receiving portion 200 may be disposed beside the oil storage chamber 100 and configured in an open structure to receive at least a portion of the muffler assembly. The "side" here is not limited to the left-right direction shown in fig. 1, but may be an up-down direction, an up-left direction, a down-right direction, or the like as long as it is disposed adjacent to the oil storage chamber 100. It should be noted that the above-mentioned "open" structure means that the accommodating portion 200 has at least one wall surface, or at least a part of the positions on one wall surface are in an open state, that is, the accommodating portion 200 is in a non-closed state, so as to be capable of adapting to muffler assemblies with different shapes and sizes. For example, in the embodiment shown in fig. 1, the receiving portion 200 may be configured as a three-face open receiving structure. In addition, in other embodiments, the receiving portion 200 may be configured to have one or both of the receiving structures with open end surfaces, which is not limited by the present disclosure.

Referring to fig. 1, the oil reservoir 100 may be constructed in a shell-like structure having an upper side opened for directly receiving oil of an upper side engine. In addition, in other embodiments, the upper end surface of the oil storage chamber 100 may be closed, the engine oil of the engine may fall onto the second housing 210, and a flow guiding groove is formed in the second housing 210, for example, a avoiding groove 211, which will be described below, may be directly used as the flow guiding groove, and the engine oil is further led into the oil storage chamber 100 through the flow guiding groove, where an oil inlet needs to be formed at a position of the oil storage chamber 100 communicating with the flow guiding groove.

Referring to fig. 1, in an embodiment of the present disclosure, the case may further include a third case 220 connected to an end of the second case 210 remote from the first case 110, wherein the first case 110, the second case 210, and the third case 220 are formed in an n-type structure to enclose the receiving part 200. In this case, the third housing 220 may be located at a cantilever end of the second housing 210 remote from the first housing 110, and the third housing 220 has a function of supporting the second housing 210 in addition to a function of enclosing the receiving portion 200. So designed, when assembling, at least part of the silencing assembly 420 can be arranged in the space surrounded by the first shell 110, the second shell 210 and the third shell 220, so that other spaces in the circumferential direction of the oil pan assembly are not required to be occupied, and the integration level and the space utilization rate in the power engine compartment are improved. In addition, this open structure is convenient to operate when arranging the muffler assembly 420, and does not require disassembly or assembly of the oil pan assembly itself.

In the embodiment of the present disclosure, the second housing 210 described above is used to form a connection with the engine block to mount the oil pan assembly to the bottom of the engine block. The present disclosure is not limited to the manner in which the second housing 210 is coupled to the engine block, and in some embodiments, may be by bolting. Further, in order to ensure the stability of the assembly of the oil pan assembly, in the embodiment of the present disclosure, the upper end surfaces of the first housing 110 and the third housing 220 may also have a connection relationship with the engine body, respectively. In addition, the third housing 220 is also used in an assembled relationship with other components within the power compartment, such as an electric motor, etc., and the present disclosure is not limited to the specific configuration of the third housing 220, which may be other structurally adapted designs that are assembled as desired.

In embodiments of the present disclosure, referring to fig. 3 and 4, the muffler assembly 420 may be partially located within the receiving portion 200, and another portion may extend outside of the receiving portion 200. Moreover, in other embodiments, the muffler assembly 420 may be entirely contained within the housing 200, as the disclosure is not limited in this regard.

The connection relationship among the first housing 110, the second housing 210 and the third housing 220 is not limited, for example, in some embodiments, the first housing 110, the second housing 210 and the third housing 220 may be integrally formed, so that the design is beneficial to reducing the assembly difficulty and the maintenance difficulty during production, and improving the use strength of the oil pan assembly. Moreover, in other embodiments, at least two of the first housing 110, the second housing 210, and the third housing 220 may be detachably coupled, such as by bolts or angle steel. By such design, only one of the first, second and third housings 110, 210 and 220 can be replaced when the other is damaged, thereby reducing maintenance costs, avoiding waste of parts, and facilitating transportation and storage. The present disclosure is not limited as to which two of the first housing 110, the second housing 210, and the third housing 220 are detachably connected, and for example, it may be that the first housing 110 and the second housing 210 are detachably connected, and the second housing 210 and the third housing 220 are integrally formed. Alternatively, the first housing 110, the second housing 210, and the third housing 220 may be detachably connected to each other.

Referring to fig. 1, in an embodiment of the present disclosure, upper end surfaces of the second housing 210, the first housing 110, and the third housing 220 may be flush. Because the oil pan assembly needs to be sealed and attached to the bottom of the engine body, the design is that when the oil pan assembly is assembled with the engine body, the flat upper surface is easier to be sealed and attached to the lower surface of the engine body. The assembly position of the bottom end of the engine body and the oil pan assembly is also generally configured to be flat, and the manner of mutually attaching the two flat structures is also more advantageous in terms of space utilization, i.e. in a limited space, the arrangement of the upper surface parallel and level can leave a larger accommodating space for the lower side of the second housing 210.

Since the oil pan assembly is required to be assembled at the lower side of the engine body having the rotating crankshaft positioned adjacent to the second housing 210, in order to prevent the second housing 210 from interfering with the rotation of the crankshaft, referring to fig. 1, in the embodiment of the present disclosure, the upper surface of the second housing 210 may be formed with a relief groove 211 for relieving the crankshaft of the engine so that the rotating crankshaft is not interfered by the second housing 210 when the engine is operated. In an embodiment of the present disclosure, the relief groove 211 may be a concave structure having an arc-shaped cross section. In addition, in other embodiments, the avoidance groove 211 may be other avoidance structures, such as a groove with a U-shaped cross section, which are adaptively formed on the upper surface of the second housing 210 according to the crankshaft envelope.

Since the first housing 110 is distant from the third housing 220, i.e., the length of the second housing 210 is long, in order to secure the use strength of the second housing 210, referring to fig. 1, in the embodiment of the present disclosure, the lower surface of the second housing 210 may be provided with the reinforcing ribs 212. The present disclosure is not limited to the shape of the reinforcing ribs 212, for example, in the embodiment of the present disclosure, the number of reinforcing ribs 212 may be plural, and the plurality of reinforcing ribs 212 may be configured in a "well" shape. Furthermore, in other embodiments, a plurality of ribs 212 may also be spaced apart from each other and arranged in parallel.

In order that the oil pan assembly may be closely fitted to the lower end surface of the engine body to prevent the engine oil from oozing out, referring to fig. 1, in the embodiment of the present disclosure, a position of the second housing 210 connected to the engine body and a position of the first housing 110 connected to the engine body may be provided with a sealing structure 300, respectively. The present disclosure is not limited to the sealing structure 300, and may be a gasket interposed therebetween. Alternatively, it may be a sealant applied therebetween.

According to a second aspect of the present disclosure, an engine is provided, including an engine body and the oil pan assembly described above, where the oil pan assembly is mounted at the bottom of the engine body, and since the engine has all the beneficial effects of the oil pan assembly described above, the description thereof is omitted here.

According to a third aspect of the present disclosure, there is provided a vehicle including a vehicle body, an exhaust system 400 and the engine described above, wherein the exhaust system 400 includes a front catalyst assembly 410, a muffler assembly 420 and a tail pipe 430 in gaseous communication in this order, and the muffler assembly 420 is at least partially disposed in the accommodating portion 200, and since the vehicle has all the advantages of the engine described above, the description thereof will not be repeated here.

Since the engine may be subject to engine shake during operation, decoupling of the engine and muffler assembly 420 is not required in order to ensure that the muffler assembly 420 may move with the engine, i.e., follow engine shake. In an embodiment of the present disclosure, the muffler assembly 420 may be fixedly connected to the engine. Specifically, referring to fig. 2, in an embodiment of the present disclosure, both sides of the muffler assembly 420 may be provided with fixing wings 800, respectively, and the fixing wings 800 may be provided with screw holes to enable the muffler assembly 420 to be assembled on the engine body by fixing bolts.

Since the exhaust gas discharged from the engine is high temperature gas, and the muffler assembly 420 is disposed adjacent to the oil storage chamber 100, when the high temperature exhaust gas enters the muffler assembly 420, heat thereof may generate a thermal damage risk to engine oil and components surrounding the muffler assembly 420 by means of heat radiation or heat transfer. To address this technical issue, in embodiments of the present disclosure, the outer surface of the muffler assembly 420 may be coated with a thermal insulating material to reduce the heat transferred outward by the muffler assembly 420. Similarly, the outer surface of the front catalytic assembly 410 may also be provided with insulation.

The present disclosure is not limited to insulating materials, and may be, for example, fiberglass wrapped around the outer surface of the front catalytic assembly 410 or the muffler assembly 420. Alternatively, in other embodiments, the aerogel insulation material (with low thermal conductivity and low acoustic impedance) coated on the outer surface of the front catalysis assembly 410 or the noise abatement assembly 420 can be used for achieving heat insulation, and can also play a role in silencing the noise abatement assembly 420, so that the overall vehicle noise design can be improved greatly.

The present disclosure is not limited in the kind of vehicle, for example, fig. 3 and 4 show a hybrid vehicle having a battery pack 500 in which an exhaust system 400 and an engine are located at the same side of the battery pack 500 in the length direction of the vehicle. By such design, the exhaust system 400 does not need to extend from one end of the vehicle, on which the engine is mounted, to the other end of the vehicle, on which the fuel tank 700 is mounted, i.e., the exhaust system 400 does not need to occupy the space of the chassis or floor of the vehicle, on which the battery pack 500 is arranged, so that the volume of the battery pack 500 can be increased, and the cruising ability of the vehicle can be improved. In addition, the vent system 400 does not need to extend to the battery pack 500 and the fuel tank 700, and the risk of the vent system 400 causing thermal damage to the battery pack 500 and the fuel tank 700 can be avoided.

Referring to fig. 3 and 4, in an embodiment of the present disclosure, a vehicle may include two rocker beams 600 symmetrically disposed on a body of the vehicle, wherein a battery pack 500 may be directly fixed between the two rocker beams 600. So that the torsional strength of the vehicle can be improved by the battery pack 500. Here, in the embodiment of the present disclosure, the battery pack 500 may be fixed to the threshold beam 600 by bolts. In addition, in other embodiments, the battery pack 500 may also be fastened to the threshold beam 600 by a snap fit, which is not limited by the present disclosure.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.

In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, the present disclosure does not further describe various possible combinations.

Moreover, any combination between the various embodiments of the present disclosure is possible as long as it does not depart from the spirit of the present disclosure, which should also be construed as the disclosure of the present disclosure.
