Description

Technical Field

[0001] This application relates to the technical field of vehicle engineering, and more specifically to a drive assembly and a vehicle. Background Technology

[0002] Currently, oil cooling is a common technology used in the industry to improve the power density of electric motors. In an oil-cooled system, an oil pump draws lubricating oil from an oil sump at the bottom of the housing and delivers it to components such as the reducer, motor stator, and motor rotor. This lubricates gears and bearings and cools the stator and rotor, resulting in higher drive efficiency, power, and torque. However, this also exposes the oil pump and related components to the bottom of the electric drive assembly. Potholes or obstacles on the road surface can damage the oil pump, thus requiring protection for the oil pump and related components. Utility Model Content

[0003] The purpose of this application is to provide a drive component and a vehicle.

[0004] This application provides a drive assembly, including: an oil pump assembly; a housing connected to the oil pump assembly; and a baffle assembly including a first baffle and a second baffle, wherein the first baffle and the second baffle are connected to both sides of the housing in the lateral direction, and the bottom sides of the first baffle and the second baffle in the vertical direction are both lower than the bottom side of the oil pump assembly in the vertical direction.

[0005] In one exemplary embodiment of this application, in the vertical direction, the end of the first baffle that is away from the housing and the end of the second baffle that is away from the housing are at the same height.

[0006] In one exemplary embodiment of this application, a portion of the first baffle extends outside the housing in the vertical direction, and / or a portion of the second baffle extends outside the housing in the vertical direction.

[0007] In one exemplary embodiment of this application, the housing includes a motor housing and a reducer housing, the motor housing and the reducer housing are connected, the first baffle and the oil pump assembly are both connected to the motor housing, and the second baffle is connected to the reducer housing.

[0008] In one exemplary embodiment of this application, the first baffle is detachably connected to the motor housing, and two first connection points are formed between the first baffle and the motor housing; and / or, the second baffle is detachably connected to the reducer housing, and two second connection points are formed between the second baffle and the reducer housing.

[0009] In one exemplary embodiment of this application, the first baffle forms a recessed area on the side opposite to the motor housing in the lateral direction, one first connection point is located in the recessed area, and another first connection point is located outside the recessed area.

[0010] In one exemplary embodiment of this application, the first baffle forms a first protrusion and a first plane on the side of the motor housing in the lateral direction. The first protrusion is correspondingly disposed with the recessed area, and the first plane is located on the periphery of the first protrusion. The baffle assembly further includes a reinforcing rib, which connects the sidewall of the first protrusion and the first plane on the side of the motor housing in the lateral direction.

[0011] In one exemplary embodiment of this application, the second baffle includes a first plate and a second plate. In the lateral direction, the width of the second plate is greater than the width of the first plate. The first plate is connected to the reducer housing, and the second plate extends in the vertical direction away from the reducer housing.

[0012] In one exemplary embodiment of this application, on the side opposite to the reducer housing in the lateral direction, the second plate protrudes from the first plate, and the second baffle further includes an inclined portion, which connects the first plate and the second plate.

[0013] This application also provides a vehicle including the aforementioned drive assembly.

[0014] This application discloses a drive assembly and a vehicle, which have the following advantages: A housing is connected to an oil pump assembly; a baffle assembly includes a first baffle and a second baffle, which are connected to the two sides of the housing in the lateral direction, and the bottom sides of both the first and second baffles in the vertical direction are lower than the bottom side of the oil pump assembly in the vertical direction. The housing houses components such as a motor stator, motor rotor, bearings, and a reducer. The oil pump assembly connected to the housing can pump lubricating oil to lubricate and cool the motor stator, motor rotor, bearings, and reducer. Because the oil pump assembly is located on the bottom side of the housing in the vertical direction, when potholes or obstacles appear on the road surface, its bottom side in the vertical direction is lower than the first and second baffles of the oil pump assembly, allowing it to preferentially contact the potholes and obstacles. The resulting collision sound and vibration are transmitted to the driver, enabling the driver to take deceleration or stopping measures in advance, thereby reducing the risk of potholes and obstacles further contacting the oil pump assembly. This design effectively protects the oil pump assembly through the baffle assembly.

[0030] Currently, oil cooling is a common technology used in the industry to improve the power density of electric motors. In an oil-cooled system, an oil pump draws lubricating oil from an oil sump at the bottom of the housing and delivers it to components such as the reducer, motor stator, and motor rotor. This lubricates gears and bearings and cools the stator and rotor, resulting in higher drive efficiency, power, and torque. However, this also exposes the oil pump and related components to the bottom of the electric drive assembly. Potholes or obstacles on the road surface can damage the oil pump, thus requiring protection for the oil pump and related components.

[0031] To address the aforementioned technical problems, this application provides a driver component, as described above. Figure 1 and Figure 2 The drive assembly includes an oil pump assembly 100, a housing 200, and a baffle assembly 300. The baffle assembly 300 includes a first baffle 310 and a second baffle 320 connected to the housing 200. The first baffle 310 and the second baffle 320 can protect the oil pump assembly 100.

[0032] In some implementations, refer to Figure 1 and Figure 2 The housing 200 is connected to the oil pump assembly 100. The baffle assembly 300 includes a first baffle 310 and a second baffle 320. The first baffle 310 and the second baffle 320 are connected to both sides of the housing 200 in the lateral direction Y. The bottom sides of the first baffle 310 and the second baffle 320 in the vertical direction Z of the housing 200 are both lower than the bottom side of the oil pump assembly 100 in the vertical direction Z. The housing 200 contains components such as a motor stator, a motor rotor, bearings, and a reducer. The oil pump assembly 100 connected to the housing 200 can pump lubricating oil to lubricate and cool the motor stator, motor rotor, bearings, and reducer. Since the oil pump assembly 100 is located on the bottom side of the housing 200 in the vertical direction Z, when potholes or obstacles appear on the road surface, the first baffle 310 and the second baffle 320 on the bottom side in the vertical direction Z are lower than the oil pump assembly 100, allowing it to preferentially contact the potholes and obstacles. The resulting collision sound and vibration will be transmitted to the driver, enabling the driver to take measures to slow down or stop in advance, thereby reducing the risk of potholes and obstacles further contacting the oil pump assembly 100. This design can effectively protect the oil pump assembly 100 through the baffle assembly 300.

[0033] In some implementations, refer to Figure 1 and Figure 2 The oil pump assembly 100 is connected to the bottom side of the housing 200 in the vertical Z direction. It utilizes gravity to assist in oil suction and optimizes oil circulation and structural compactness. Therefore, the first baffle 310 and the second baffle 320 are also located on the bottom side of the housing 200. Specifically, the oil pump assembly 100 includes an oil pump, an oil suction port, an oil sump, and a pump chamber. When the oil pump is working, it needs to draw oil from the oil sump into the pump chamber through the oil suction port. The oil pump assembly 100, located on the bottom side of the housing 200 in the vertical Z direction, can have its oil suction port directly close to the oil surface (or immersed in the oil). It reduces the oil suction resistance by utilizing gravity and reduces the "dry suction" phenomenon caused by excessively long oil suction paths or excessively high positions. The bottom of the housing 200 is typically an area where oil naturally accumulates. Positioning the oil pump assembly 100 at the bottom of the housing 200 shortens the suction line length, reduces pressure loss along the line, and improves pump efficiency. Simultaneously, the bottom position allows the housing 200's own structure to protect the oil pump, reducing the impact of external shocks, and facilitates direct integration with other components (such as filters and pressure valves) through the internal oil passages of the housing 200, simplifying the overall hydraulic / lubrication system layout. Therefore, it is necessary to position the first baffle 310 and the second baffle 320 on the bottom of the housing 200 in the vertical Z direction.

[0034] In some implementations, refer to Figure 1 and Figure 2In the vertical direction Z, the ends of the first baffle 310 and the second baffle 320 that are opposite to the housing 200 are at the same height. When the vehicle encounters potholes or obstacles while driving, the first baffle 310 and the second baffle 320 can simultaneously sense contact information at the same height. This symmetrical and coordinated arrangement greatly reduces the possibility of misjudgment by the driver due to feedback from one side, thereby significantly improving driving safety and driving comfort.

[0035] In some implementations, refer to Figure 1 and Figure 2 A portion of the first baffle 310 extends beyond the housing 200 in the vertical direction Z, and / or a portion of the second baffle 320 extends beyond the housing 200 in the vertical direction Z. The extension of the first baffle 310 and / or the second baffle 320 beyond the housing 200 is such that the bottom side of the first baffle 310 and / or the second baffle 320 in the vertical direction Z is lower than the bottom side of the oil pump assembly 100 in the vertical direction Z. Specifically, the height at which the first baffle 310 and the second baffle 320 extend beyond the housing 200 in the vertical direction Z can be determined according to the height of the oil pump assembly 100, and the distance between the bottom side of the first baffle 310 and the oil pump assembly 100, and the distance between the second baffle 320 and the oil pump assembly 100 can also be determined according to actual needs.

[0036] In some implementations, refer to Figure 1 and Figure 2 The first baffle 310 and / or the second baffle 320 are inclined. Specifically, taking the first baffle 310 as an example, one end of the first baffle 310 is connected to the housing 200, and the other end extends in the vertical direction Z while being inclined to the rear in the forward and backward direction X. Since vehicles mostly travel forward, when encountering potholes and obstacles while traveling forward, the inclined first baffle 310 and second baffle 320 can gradually come into contact with the potholes and obstacles, guiding the collision and contact and giving the driver more time to react. The second baffle 320 can also be arranged correspondingly to the first baffle 310 and can achieve the same and corresponding technical effect as the first baffle 310.

[0037] In some implementations, the forward / backward direction X is the vehicle's driving direction, the lateral direction Y is the vehicle's left / right direction, and the vertical direction Z is the vehicle's up / down direction. The forward / backward direction X, the lateral direction Y, and the vertical direction Z are all perpendicular to each other.

[0038] In some implementations, refer to Figure 1 and Figure 2The housing 200 includes a motor housing 210 and a reducer housing 220, which are connected. The first baffle 310 and the oil pump assembly 100 are both connected to the motor housing 210, and the second baffle 320 is connected to the reducer housing 220. The motor provides a power source for the oil pump assembly 100, which then transports the oil from the oil pump housing 200 to the motor stator, motor rotor, and reducer. Specifically, the oil pump assembly 100 is connected to the bottom of the housing 200 in the vertical Z direction. Since the motor housing 210 has a relatively small width in the horizontal direction, and the first baffle 310 and the second baffle 320 might interfere with the oil pump assembly 100, the second baffle 320 can be connected to the reducer housing 220 to facilitate the installation of the first baffle 310 and the second baffle 320.

[0039] In some implementations, refer to Figure 1 and Figure 2 The first baffle 310 is detachably connected to the motor housing 210, forming two first connection points 410 between the first baffle 310 and the motor housing 210; and / or, the second baffle 320 is detachably connected to the reducer housing 220, forming two second connection points 420 between the second baffle 320 and the reducer housing 220. This design facilitates production and assembly, allowing the first baffle 310 or the second baffle 320 to be removed during production, preventing them from causing inconvenience to assembly and manufacturing, and improving assembly efficiency. Simultaneously, the two connection points prevent the baffle from rotating when in contact with pits / obstacles, increasing the stability of the connection between the baffle and the housing 200. Specifically, the first baffle 310 can be provided only on the motor housing 210, or the second baffle 320 can be provided only on the reducer housing 220, or both can be provided simultaneously, depending on actual needs.

[0040] In one specific implementation, refer to Figures 3 to 5 On one side of the motor housing 210 in the lateral direction Y, a first locking hole 211 is formed, and a first baffle 310 has a second locking hole 314 corresponding to the first locking hole 211. There are two locking holes: the first locking hole 211 and the second locking hole 314. Figure 1 As shown, the drive assembly includes two first locking members 510, which are respectively inserted into corresponding first locking holes 211 and second locking holes 314. (Refer to...) Figure 6 and Figure 7 On the other side of the reducer housing 220 in the transverse Y direction, a third locking hole 221 is formed, and a fourth locking hole 324 corresponding to the third locking hole 221 is formed on the second baffle 320. There are two locking holes: the third locking hole 221 and the fourth locking hole 324. Figure 2As shown, the drive assembly includes two second locking members 520, which are respectively inserted into corresponding third locking holes 221 and fourth locking holes 324. Each corresponding first locking hole 211, second locking hole 314, and first locking member 510 form a connection point, thereby forming two first connection points 410. Each corresponding third locking hole 221, fourth locking hole 324, and second locking member 520 form a connection point, thereby forming two second connection points 420.

[0041] In some implementations, refer to Figure 3 The first baffle 310 forms a recessed area 311 on the side facing away from the motor housing 210 in the lateral direction Y. One first connection point 410 is located in the recessed area 311, and the other first connection point 410 is located outside the recessed area 311. This design allows at least one of the first connection points 410's first locking member 510 to be placed in the recessed area 311, thereby reducing the lateral installation space of the first locking member 510 and reducing the risk of interference between the mounting head of the first locking member 510 and other components. Specifically, the depth of the recess can be set according to the height of the head of the first locking member 510.

[0042] In some implementations, combined Figure 1 and Figure 2 The first locking member 510 and the second locking member 520 are bolts, and the first locking hole 211, the second locking hole 314, the third locking hole 221, and the fourth locking hole 324 are threaded holes. In other embodiments, the second locking hole 314 and the fourth locking hole 324 are configured as through holes, and the first locking member 510 and the second locking member 520 pass through the third locking hole 221 and the fourth locking hole 324 respectively and are threadedly connected to the first locking hole 211 and the second locking hole 314.

[0043] In some implementations, refer to Figure 4 The first baffle 310 has a first protrusion 312 and a first plane 313 on the side of the motor housing 210 in the transverse direction Y. The first protrusion 312 is correspondingly disposed with a recessed area 311, and the first plane 313 is located on the periphery of the first protrusion 312. The baffle assembly 300 also includes a reinforcing rib 330, which connects the sidewall of the first protrusion 312 and the first plane 313 on the side of the motor housing 210 in the transverse direction Y. The corresponding first protrusion 312 and recessed area 311 can increase the thickness of the first baffle 310, thereby increasing the structural strength of the first baffle 310. At the same time, in order to reduce the stress after the first protrusion 312 protrudes, the sidewall of the first protrusion 312 and the first plane 313 are connected by the reinforcing rib 330, which can increase the structural strength of the first protrusion 312.

[0044] In some implementations, refer to Figure 4 Multiple reinforcing ribs 330 are provided, and these ribs 330 are distributed at intervals along the circumference of the first protrusion 312. This allows for a more uniform distribution of the stress borne by the first protrusion 312, further enhancing its structural stability. Moreover, the arrangement of the multiple reinforcing ribs 330 can be flexibly adjusted according to the specific shape and stress conditions of the first protrusion 312 to better meet the structural strength requirements under different working conditions. The cross-sectional shape of the reinforcing ribs 330 can be designed as trapezoidal or triangular, etc. Different cross-sectional shapes of the reinforcing ribs 330 have different effects on stress distribution and structural strength enhancement, and can be selected according to actual needs.

[0045] In some implementations, refer to Figure 6 The second baffle 320 includes a first plate 321 and a second plate 322. In the transverse direction Y, the width of the second plate 322 is greater than the width of the first plate 321. The first plate 321 is connected to the reducer housing 220. The second plate 322 extends in the vertical direction Z away from the reducer housing 220. This structural arrangement gives the second baffle 320 a wider width in the transverse direction Y, enhancing its stability. Simultaneously, the extension of the second plate 322 in the vertical direction Z, since the second baffle 320 is the main part in contact with potholes and obstacles, further ensures its service life by increasing its thickness. The connection method between the first plate 321 and the reducer housing 220 can be welding, bolting, or other methods, selected according to the specific usage environment and requirements to ensure the strength and reliability of the connection.

[0046] In some implementations, refer to Figure 4 On the side facing away from the reducer housing 220 in the transverse Y direction, a second plate 322 protrudes from the first plate 321. The second baffle 320 also includes an inclined portion 323, which connects the first plate 321 and the second plate 322. This combination of protrusion and inclined portion 323 makes the second baffle 320 structurally more stable and better able to withstand external impacts and pressures. The design of the inclined portion 323 not only increases the overall strength of the second baffle 320, but also allows it to more effectively disperse stress when subjected to external forces, avoiding damage caused by localized stress concentration. At the same time, this structural form also helps to guide external impurities or liquids to slide down along the inclined portion 323, further reducing the possibility of them entering the reducer. In actual manufacturing, the angle and length of the inclined portion 323 can be adjusted according to specific needs to achieve the best structural effect and protective performance.

[0047] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
