Abstract
Description
Technical Field
[0001] This application belongs to the technical field of engines, specifically relating to an oil pan assembly. Background Technology
[0002] The lubrication system is a key system to ensure the normal operation of internal engine components. It uses engine oil to form an oil film on the outside of the internal engine components to reduce friction. Good lubrication can reduce wear on internal engine components, reduce fuel consumption, and improve power output efficiency. However, poor lubrication will aggravate wear on internal engine components, and in severe cases, it may even lead to cylinder scoring, bearing failure, and other problems.
[0003] However, since the temperature of the engine oil affects its viscosity, and the viscosity of the engine oil affects its flowability, when the vehicle is parked in cold weather, the engine oil in the oil pan has a higher viscosity due to the low ambient temperature. This results in poorer flowability, meaning that when the vehicle is cold-started, the engine oil in the oil pan needs a longer time to reach the various parts inside the engine that require lubrication. Before the engine oil reaches these parts, the movement of the parts lacks lubrication, resulting in dry friction, which accelerates the wear of the parts' surfaces and may even cause damage.
[0004] To reduce wear on parts and extend their lifespan, engines capable of preheating engine oil before a cold start have emerged. This is achieved by installing a heating film on the outside of the oil pan, which heats the oil pan and thus raises its temperature, thereby heating the oil inside. However, during oil preheating, the heating film must first transfer heat to the oil pan, which then transfers heat to the oil. This process results in heat loss, affecting preheating efficiency and extending the preheating time. Utility Model Content
[0005] This application provides an oil pan assembly to ensure efficient preheating of engine oil and reduce the time required for preheating the engine oil.
[0006] The technical solution adopted in this application is as follows:
[0007] An oil pan assembly, comprising:
[0008] An oil pan body, wherein the interior of the oil pan body has an oil-containing cavity;
[0009] A heating element is located in the oil chamber and is used to heat the engine oil located in the oil chamber.
[0010] An oil stirring assembly includes stirring blades and a drive unit. The stirring blades are located in the oil receiving chamber, and the drive unit is located outside the oil pan body. The output shaft of the drive unit extends into the oil receiving chamber and is connected to the stirring blades, so that the drive unit can drive the stirring blades to rotate to stir the oil in the oil receiving chamber.
[0011] By adopting the above technical solution, before a vehicle equipped with the oil pan assembly described in this application needs to be cold-started in cold weather, the vehicle is first powered on, and then the vehicle's battery supplies power to the heating element and the drive unit. This allows the heating element to heat the engine oil located in the oil chamber, while the output shaft of the drive unit drives the stirring blades to rotate, thus agitating the engine oil in the oil chamber. This results in more uniform heating of the engine oil in the oil chamber, improving the preheating efficiency of the engine oil and shortening the time required for preheating. Furthermore, compared to the prior art solution that uses a heating film to heat the oil pan, the heating element in this application directly heats the engine oil, greatly reducing heat loss and significantly improving the preheating efficiency of the engine oil. Moreover, due to the improved preheating efficiency, the waiting time required by the driver before a cold start is greatly shortened, improving the driver's experience and increasing the vehicle's operating efficiency.
[0012] Optionally, the heating element is a mesh-like heating wire, the outer contour of which is adapted to the shape of the oil-containing cavity.
[0013] By adopting the above technical solution, since the heating wire is mesh-like and its outer contour is adapted to the shape of the oil cavity, the heating area of the heating wire is increased, thereby improving the preheating efficiency of the oil in the oil cavity. At the same time, compared with the solution using a heating film in the prior art, it reduces the production cost of the oil pan assembly and allows the oil in the oil cavity to flow on both sides of the heating wire, so as to ensure the fluidity of the oil in the oil cavity.
[0014] Optionally, the heating wire has an insulating layer on its exterior, the thickness of which is less than the diameter of the heating wire.
[0015] By adopting the above technical solution, the heating wire has an insulating layer on the outside, which realizes the electrical isolation between the heating wire and the oil pan body, so as to prevent the heating wire from being electrically connected to the oil pan body; since the thickness of the insulating layer is smaller than the diameter of the heating wire, the heat generated by the heating wire can be quickly transferred to the oil in the oil chamber through the insulating layer, thereby improving the preheating efficiency of the oil.
[0016] Optionally, a support block is provided between the wall of the oil-containing cavity and the heating wire, the support block having a positioning groove, and the heating wire being located in the positioning groove.
[0017] By adopting the above technical solution, a support block is provided between the cavity wall of the oil-containing chamber and the heating wire, which supports the heating wire and creates a gap between the heating wire and the cavity wall of the oil-containing chamber. This prevents the heating wire from transferring heat to the oil pan body, ensuring that all the heat generated by the heating wire is transferred to the oil in the oil-containing chamber, thereby further improving the preheating efficiency of the oil. Furthermore, the support block has a positioning groove in which the heating wire is located, allowing for positioning of the heating wire and increasing the connection stability between the heating wire and the support block, thus ensuring the support effect of the support block on the heating wire.
[0018] Optionally, the support block is provided with a fixing frame, which is located outside the heating wire. One of the support block and the fixing frame is provided with a snap-fit hole, and the other of the two is provided with a snap-fit block that snaps into the snap-fit hole.
[0019] And / or, the oil pan body is ferromagnetic, and the support block is provided with a magnetic block on the side opposite to the heating wire that magnetically engages with the cavity wall of the oil-containing cavity.
[0020] By adopting the above technical solution, since the fixing bracket is set outside the heating wire, the heating wire can be fixed to the support block using the fixing bracket, thereby further increasing the connection stability between the heating wire and the support block, and further improving the support effect of the support block on the heating wire; since one of the support block and the fixing bracket is provided with a snap-fit hole, and the other of the two is provided with a snap-fit block that snaps into the snap-fit hole, when installing the fixing bracket, it is only necessary to snap the snap-fit block into the snap-fit hole, thereby reducing the installation difficulty of the fixing bracket and improving the assembly efficiency of the oil pan assembly.
[0021] Because the side of the support block away from the heating wire is equipped with a magnetic block that magnetically engages with the wall of the oil chamber, the support block is connected to the oil pan body to increase its stability, thereby increasing the support stability of the heating wire. On the other hand, the magnetic block can also be used to attract iron filings in the oil to prevent them from mixing in the oil and damaging the internal engine components, thus extending the service life of the internal engine components.
[0022] Optionally, the bottom of the oil pan body is provided with a protrusion protruding into the interior of the oil-containing cavity, and the interior of the protrusion forms a downward-facing mounting cavity, in which at least a portion of the drive member is located.
[0023] By adopting the above technical solution, since at least part of the drive component is located in the mounting cavity, on the one hand, the length of the drive component protruding from the bottom of the oil pan body is reduced to ensure the vehicle's passability; on the other hand, the mounting cavity can be used to position the drive component to increase its stability; and on the other hand, the height of the stirring blade can be raised so that the stirring blade is as close as possible to the middle position in the height direction of the oil pan body, thereby improving the stirring effect of the stirring blade on the oil in the oil chamber and further improving the preheating efficiency of the oil.
[0024] Optionally, the top of the protrusion has an oil guiding surface, the oil guiding surface has a central area and a side area surrounding the central area, and the oil guiding surface is inclined downward from the central area to the side area.
[0025] By adopting the above technical solution, since the top of the protrusion has an oil guiding surface, which is inclined downward from the center area to the side area, when the engine oil is changed, the engine oil adhering to the oil guiding surface can flow from the center area to the side area, so as to drain the engine oil in the oil chamber, thereby avoiding the situation of engine oil accumulating on the oil guiding surface.
[0026] Optionally, a support bracket is provided at the bottom of the oil pan body, at least a portion of which is located at the bottom of the drive member, so that the support bracket can apply a supporting force to the drive member toward the interior of the oil cavity.
[0027] By adopting the above technical solution, since at least part of the support bracket is located at the bottom of the drive component, the support bracket can be used to support the drive component, thereby fixing the drive component. At the same time, it can reduce the difficulty of fixing the drive component, and the support bracket can also protect the drive component to a certain extent to avoid damage caused by the drive component being impacted by external forces, thus ensuring the service life of the drive component.
[0028] Optionally, the support bracket has a connecting section that abuts against the oil pan body, and the bottom of the oil pan body is provided with a screw that passes through the connecting section, and the screw is threadedly connected to a nut located at the bottom of the connecting section.
[0029] By adopting the above technical solution, since the bottom of the oil pan body is provided with a screw that passes through the connecting section, and the screw is threadedly connected to a nut located at the bottom of the connecting section, the connecting section can be fixedly connected to the oil pan body using the screw and nut, thereby reducing the difficulty of fixing the support bracket, improving the fixing efficiency of the support bracket, and also increasing the connection stability between the support bracket and the oil pan body; in addition, compared with the solution of fixing the support bracket using bolts threaded to the bottom of the oil pan body, the screw solution in this application ensures the structural strength of the oil pan body.
[0030] Optionally, the oil pan assembly further includes a temperature sensor disposed in the oil chamber, the temperature sensor being used to detect the temperature of the engine oil located in the oil chamber.
[0031] By adopting the above technical solution, since a temperature sensor is installed in the oil chamber, the temperature of the oil in the oil chamber can be detected by the temperature sensor. Before the vehicle is started, the heating element and the drive element can be controlled to start based on the oil temperature detected by the temperature sensor. When the oil temperature reaches the set value, the heating element and the drive element can also be controlled to shut down based on the oil temperature detected by the temperature sensor.
[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0033] 1. The oil pan assembly of this application includes an oil pan body, a heating element, and an oil agitation assembly. The oil pan body has an internal oil-containing cavity, and the heating element is located within the oil-containing cavity to heat the engine oil within it. The oil agitation assembly includes stirring blades and a driving element. The stirring blades are located within the oil-containing cavity, and the driving element is located outside the oil pan body. The output shaft of the driving element extends into the oil-containing cavity and is connected to the stirring blades, enabling the driving element to drive the stirring blades to rotate and agitate the engine oil within the oil-containing cavity. Vehicles equipped with this oil pan assembly can be started in cold weather by first ventilating the vehicle... Electricity powers the vehicle's battery to supply power to the heating element and drive unit, enabling the heating element to heat the oil in the oil chamber. Simultaneously, the output shaft of the drive unit rotates the stirring blades, agitating the oil in the oil chamber. This results in more uniform heating of the oil, improving preheating efficiency and shortening the preheating time. Furthermore, compared to existing technologies that use a heating film to heat the oil pan, the heating element in this application directly heats the oil, significantly reducing heat loss and thus greatly improving preheating efficiency.
[0034] 2. The heating element in this application is a mesh-like heating wire. The outer contour of the heating wire is adapted to the shape of the oil cavity, thereby increasing the heating area of the heating wire and improving the preheating efficiency of the oil in the oil cavity. At the same time, compared with the heating film solution in the prior art, it reduces the manufacturing cost of the oil pan assembly and allows the oil in the oil cavity to flow on both sides of the heating wire to ensure the fluidity of the oil in the oil cavity.
[0035] 3. The heating wire in this application has an insulating layer on the outside, which realizes the electrical isolation between the heating wire and the oil pan body, so as to prevent the heating wire from being electrically connected to the oil pan body. The thickness of the insulating layer is smaller than the diameter of the heating wire, so that the heat generated by the heating wire can be quickly transferred to the oil in the oil chamber through the insulating layer, thereby improving the preheating efficiency of the oil.

[0044] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.
[0045] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.
[0049] Reference Figures 1 to 5 An oil pan assembly is disclosed, comprising an oil pan body 1, a heating element, and an oil stirring assembly 3. The oil pan body 1 has an oil receiving cavity inside. The heating element is located in the oil receiving cavity and is used to heat the oil in the oil receiving cavity. The oil stirring assembly 3 includes a stirring blade 31 and a driving element 32. The stirring blade 31 is located in the oil receiving cavity, and the driving element 32 is located outside the oil pan body 1. The output shaft of the driving element 32 extends into the oil receiving cavity and is connected to the stirring blade 31 so that the driving element 32 can drive the stirring blade 31 to rotate to stir the oil in the oil receiving cavity.
[0050] Before a vehicle equipped with the oil pan assembly described in this application needs to be cold-started in cold weather, the vehicle is first powered on, and the vehicle battery then supplies power to the heating element and the drive unit 32. This allows the heating element to heat the engine oil located in the oil chamber, while the output shaft of the drive unit 32 drives the stirring blade 31 to rotate, thus agitating the engine oil in the oil chamber. This results in more uniform heating of the engine oil in the oil chamber, improving the preheating efficiency of the engine oil and shortening the time required for preheating. Furthermore, compared to the prior art method of using a heating film located outside the oil pan to heat the oil pan, the heating element in this application directly heats the engine oil, greatly reducing heat loss and significantly improving the preheating efficiency of the engine oil. Moreover, due to the improved preheating efficiency of the engine oil, the waiting time required by the driver before cold-starting the vehicle is greatly shortened, thereby improving the driver's experience and the vehicle's operating efficiency.
[0051] In order to enable the vehicle's electronic control unit (ECU) to control the heating element and the drive element 32, both the heating element and the drive element 32 are electrically connected to the vehicle's relays, and the relays are electrically connected to the electronic control unit, so that the electronic control unit can control the relays to energize or de-energize the heating element and the drive element 32.
[0052] This application does not specifically limit the structure of the heating element; however, preferred embodiments are described below. Figure 1 and Figure 4 The heating element is a mesh-like heating wire 2, and the outer contour of the heating wire 2 is adapted to the shape of the oil cavity.
[0053] It is understandable that the heating element is a mesh structure made of interwoven heating wires 2, and the outer contour of the mesh structure is adapted to the shape of the oil cavity.
[0054] Since the heating wire 2 is mesh-like and its outer contour is adapted to the shape of the oil cavity, the heating area of the heating wire 2 is increased, thereby improving the preheating efficiency of the oil in the oil cavity. At the same time, compared with the existing technology that uses a heating film, it reduces the production cost of the oil pan assembly and allows the oil in the oil cavity to flow on both sides of the heating wire 2 to ensure the fluidity of the oil in the oil cavity.
[0055] Furthermore, refer to Figure 2 and Figure 3 The heating wire 2 has an insulating layer 21 on its outside, and the thickness of the insulating layer 21 is smaller than the diameter of the heating wire 2.
[0056] Because the heating wire 2 has an insulating layer 21 on its outside, the heating wire 2 is electrically isolated from the oil pan body 1, so as to prevent the heating wire 2 from being electrically connected to the oil pan body 1. Because the thickness of the insulating layer 21 is smaller than the diameter of the heating wire 2, the heat generated by the heating wire 2 can be quickly transferred to the oil in the oil chamber through the insulating layer 21, thereby improving the preheating efficiency of the oil.
[0057] This application does not specifically limit the material of the insulating layer 21. Preferably, the insulating layer 21 is made of plastic to ensure the shape stability of the mesh heating wire 2. In other embodiments, the insulating layer 21 may also be made of other materials, such as silicone rubber.
[0058] This application does not specify the installation method of the heating wire 2; preferably, refer to... Figure 2 and Figure 3 A support block 11 is provided between the wall of the oil-containing cavity and the heating wire 2. The support block 11 has a positioning groove 111, and the heating wire 2 is located in the positioning groove 111.
[0059] It should be noted that the heating wire 2 being located in the positioning groove 111 as mentioned above refers to the insulation layer 21 outside the heating wire 2 being located in the positioning groove 111.
[0060] Understandably, multiple support blocks 11 are spaced apart to ensure effective support for the heating wire 2.
[0061] Because a support block 11 is provided between the wall of the oil-containing cavity and the heating wire 2, the support block 11 can support the heating wire 2, creating a gap between the heating wire 2 and the wall of the oil-containing cavity. This prevents the heating wire 2 from transferring heat to the oil pan body 1, ensuring that all the heat generated by the heating wire 2 is transferred to the oil in the oil-containing cavity, thereby further improving the preheating efficiency of the oil. Since the support block 11 is provided with a positioning groove 111, the heating wire 2 is located in the positioning groove 111, which can then be used to position the heating wire 2, increasing the connection stability between the heating wire 2 and the support block 11, and thus ensuring the supporting effect of the support block 11 on the heating wire 2. Furthermore, by providing the positioning groove 111, the support block 11 and the heating wire 2 can be mutually restrained, increasing the stability of the support block 11 and preventing relative movement between the support block 11 and the heating wire 2.
[0062] Furthermore, refer to Figure 2 and Figure 3 The support block 11 is provided with a fixing frame 12, which is located outside the heating wire 2. One of the support block 11 and the fixing frame 12 is provided with a snap-fit hole 121, and the other is provided with a snap-fit block 112 that snaps into the snap-fit hole 121.
[0063] It should be noted that the aforementioned fixing frame 12 located outside the heating wire 2 refers to the fixing frame 12 being located outside the insulating layer 21 located outside the heating wire 2; a fixing cavity for accommodating the heating wire 2 is formed between the fixing frame 12 and the support block 11, so as to fix the heating wire 2 by applying a pressing force to the heating wire 2 in the direction close to the support block 11 using the fixing frame 12.
[0064] Since the mounting bracket 12 is located outside the heating wire 2, the heating wire 2 can be fixed to the support block 11 using the mounting bracket 12, thereby further increasing the connection stability between the heating wire 2 and the support block 11, and further improving the support effect of the support block 11 on the heating wire 2. Since one of the support block 11 and the mounting bracket 12 is provided with a snap-fit hole 121, and the other is provided with a snap-fit block 112 that snaps into the snap-fit hole 121, when installing the mounting bracket 12, it is only necessary to snap the snap-fit block 112 into the snap-fit hole 121, thereby reducing the difficulty of installing the mounting bracket 12 and improving the assembly efficiency of the oil pan assembly.
[0065] The better one is to refer to Figure 3 The fixing frame 12 has locking holes 121 on both sides, and the support block 11 has locking blocks 112 on both sides. After the fixing frame 12 is installed on the support block 11, the locking blocks 112 on both sides of the support block 11 engage with the locking holes 121 on both sides of the fixing frame 12 to increase the connection stability between the fixing frame 12 and the support block 11.
[0066] Furthermore, the fixing frame 12 is elastic, and the side of the snap-fit block 112 away from the wall of the oil cavity is provided with a guide surface. When the fixing frame 12 is installed, the opposite sides of the fixing frame 12 can deform in opposite directions under the action of the guide surface, so that the two sides of the fixing frame 12 avoid the snap-fit block 112. When the snap-fit hole 121 of the fixing frame 12 moves to the position of the snap-fit block 112, the fixing frame 12 returns to its original shape, so that the snap-fit block 112 is located in the snap-fit hole 121, thereby completing the assembly of the fixing frame 12.
[0067] Preferably, the fixing bracket 12 is made of plastic material so that the fixing bracket 12 has a certain elastic deformation capability, thereby reducing the difficulty of installing the fixing bracket 12.
[0068] The better one is to refer to Figure 2 and Figure 3 The distance between the two sides of the support block 11 gradually increases in the direction away from the heating wire 2. The shape of the fixing frame 12 is adapted to the shape of the support block 11 to reduce the installation difficulty of the fixing frame 12 and thus improve the fixing efficiency of the heating wire 2.
[0069] This application does not specifically limit the connection relationship between the support block 11 and the wall of the oil-containing cavity. Preferably, refer to... Figure 3 The oil pan body 1 is ferromagnetic, and the support block 11 is provided with a magnetic block 113 on the side opposite to the heating wire 2, which magnetically engages with the cavity wall of the oil chamber.
[0070] It is understandable that the oil pan body 1 is made of iron material so that the oil pan body 1 has ferromagnetism.
[0071] Since the support block 11 has a magnetic block 113 on the side opposite to the heating wire 2 that magnetically engages with the cavity wall of the oil chamber, the support block 11 is connected to the oil pan body 1, thereby increasing the stability of the support block 11 and thus increasing the support stability of the heating wire 2. On the other hand, the magnetic block 113 can also be used to attract iron filings in the engine oil, so as to avoid the situation where iron filings are mixed in the engine oil and cause damage to the internal parts of the engine, thereby extending the service life of the internal parts of the engine.
[0072] Preferably, the support block 11 is made of plastic material to reduce the production cost of the support block 11, and the magnetic block 113 is fixedly connected to the support block 11 to increase the connection stability between the support block 11 and the wall of the oil-containing cavity.
[0073] In other implementation examples, the support block 11 can also be fixedly connected to the cavity wall of the oil-containing cavity by adhesive bonding.
[0074] In other embodiments, the heating wire 2 can also be directly fixed to the wall of the oil-containing cavity by adhesive bonding or by fasteners.
[0075] In other embodiments, the heating element may also be a strip heating film or other structure capable of heating the oil.
[0076] This application does not specifically limit the positional relationship between the drive member 32 and the oil pan body 1. Preferably, the drive member 32 is located at the center of the oil pan body 1, thereby ensuring that the stirring blade 31 is also located at the center of the oil pan body 1, so as to ensure the agitation effect on the oil. In other embodiments, the drive member 32 may also be located on the side of the oil pan body 1, as long as it can ensure that the stirring blade 31 avoids contact with the heating wire 2 and the cavity wall of the oil receiving chamber.
[0077] This application does not specifically limit the structure of the drive component 32. Preferably, the drive component 32 is a motor to reduce the manufacturing cost of the oil pan assembly. In other embodiments, the drive component 32 may also be a pneumatic motor or other structure capable of driving the stirring blades 31 to rotate.
[0078] In a preferred embodiment, the stirring blade 31 includes a rotating disk and a plurality of stirring blades. The plurality of stirring blades are evenly spaced along the circumference of the rotating disk, and each stirring blade is fixedly connected to the rotating disk. The rotating disk is coaxially fixedly connected to the output shaft of the drive unit 32.
[0079] In a preferred embodiment, refer to Figure 1 and Figure 4 The bottom of the oil pan body 1 is provided with a protrusion 13 protruding into the oil cavity, and the interior of the protrusion 13 forms a downward-facing mounting cavity 131, in which at least a portion of the drive member 32 is located.
[0080] It is understandable that the drive unit 32 is located at the bottom of the oil pan body 1, and the protrusion 13 is provided with a through hole for the output shaft of the drive unit 32 to pass through.
[0081] Since at least a portion of the drive component 32 is located in the mounting cavity 131, on the one hand, the length of the drive component 32 protruding from the bottom of the oil pan body is reduced to ensure the vehicle's passability; on the other hand, the mounting cavity 131 can be used to position the drive component 32 to increase its stability; and on the other hand, the height of the stirring blade 31 can be raised so that the stirring blade 31 is as close as possible to the middle position in the height direction of the oil pan body, thereby improving the stirring effect of the stirring blade 31 on the oil in the oil chamber, and further improving the preheating efficiency of the oil.
[0082] Preferably, a sealing ring is provided between the wall of the through hole and the output shaft to seal the gap between the output shaft and the wall of the through hole, thereby increasing the sealing performance between the output shaft and the wall of the through hole.
[0083] Furthermore, refer to Figure 1 and Figure 4 The top of the protrusion 13 has an oil guiding surface 132, which has a central area and a side area surrounding the central area. The oil guiding surface 132 is inclined downward from the central area to the side area.
[0084] Since the top of the protrusion 13 has an oil guiding surface 132, which is inclined downward from the center area to the side area, when the engine oil is changed, the engine oil adhering to the oil guiding surface 132 can flow from the center area to the side area, so as to drain the engine oil in the oil chamber and avoid the accumulation of engine oil on the oil guiding surface 132.
[0085] This application does not specifically limit the shape of the oil guiding surface 132. Preferably, the oil guiding surface 132 is spherical to increase the oil guiding effect. In other embodiments, the oil guiding surface 132 may also be an inclined surface that slopes from the center to the side.
[0086] This application does not specify the fixing method of the driving component 32; preferably, refer to... Figure 1 , Figure 4 and Figure 5 The bottom of the oil pan body 1 is provided with a support bracket 14, at least a portion of which is located at the bottom of the drive member 32, so that the support bracket 14 can apply a supporting force to the drive member 32 toward the interior of the oil chamber.
[0087] Understandably, the drive component 32 is fixedly connected to the oil pan body 1 by the compression of the support bracket 14.
[0088] Since at least part of the support bracket 14 is located at the bottom of the drive member 32, the drive member 32 can be supported by the support bracket 14 to fix the drive member 32, which can also reduce the difficulty of fixing the drive member 32. In addition, the support bracket 14 can also protect the drive member 32 to a certain extent to avoid damage caused by the drive member 32 being impacted by external forces, thereby ensuring the service life of the drive member 32.
[0089] The better one is to refer to Figure 1 , Figure 2 and Figure 5 The support frame 14 is U-shaped, which simplifies the structural design of the support frame 14 and reduces the production cost of the support frame 14.
[0090] Furthermore, the support bracket 14 has a connecting section 141 that abuts against the oil pan body 1. The bottom of the oil pan body 1 is provided with a screw 15 that passes through the connecting section 141. The screw 15 is threadedly connected to a nut 151 located at the bottom of the connecting section 141.
[0091] It is understood that the support bracket 14 has connecting sections 141 on both sides that abut against the oil pan body 1. The bottom of the oil pan body 1 is provided with two screws 15 corresponding to the two connecting sections 141, and each connecting section 141 is provided with a hole for the screws 15 to pass through. Each screw 15 is threaded with a nut 151 located at the bottom of the connecting section 141.
[0092] Since the bottom of the oil pan body 1 is provided with a screw 15 passing through the connecting section 141, and the screw 15 is threadedly connected to a nut 151 located at the bottom of the connecting section 141, the connecting section 141 can be fixedly connected to the oil pan body 1 by means of the screw 15 and the nut 151, thereby reducing the difficulty of fixing the support bracket 14, improving the fixing efficiency of the support bracket 14, and also increasing the connection stability between the support bracket 14 and the oil pan body 1; in addition, compared with the solution of fixing the support bracket 14 by means of bolts threaded to the bottom of the oil pan body 1, the solution of using screw 15 in this application ensures the structural strength of the oil pan body 1.
[0093] In other embodiments, the drive unit 32 can also be fixedly connected to the oil pan body 1 using fasteners, for example, by using bolts to fix the connecting seat of the drive unit 32 to the oil pan body 1.
[0094] In a preferred embodiment, refer to Figure 1 The oil pan assembly also includes a temperature sensor 4 located in the oil chamber, which is used to detect the temperature of the engine oil in the oil chamber.
[0095] Since a temperature sensor 4 is installed in the oil chamber, the temperature of the oil in the oil chamber can be detected by the temperature sensor 4. Before the vehicle is started, the heating element and the drive element 32 can be controlled to start based on the oil temperature detected by the temperature sensor 4. When the oil temperature reaches the set value, the heating element and the drive element 32 can also be controlled to shut down based on the oil temperature detected by the temperature sensor 4.
[0096] Preferably, the temperature sensor 4 is connected to the vehicle's electronic controller so that the vehicle's electronic controller can control the heating element and the drive element 32 to be powered or de-powered according to the oil temperature signal emitted by the temperature sensor 4 via a relay.
[0097] This application does not specifically limit the location of the temperature sensor 4. Preferably, the temperature sensor 4 is located on the side of the protrusion 13 so that it can avoid contact with the stirring blade 31, ensuring the normal operation of both the stirring blade 31 and the temperature sensor 4, and also reducing the failure rate of the oil pan assembly. In other embodiments, the temperature sensor 4 can also be located at other positions in the oil chamber, as long as it can ensure that the temperature sensor 4 can detect the temperature of the oil in the oil chamber and avoid contact with the stirring blade 31.
