Description

Technical Field

[0001] This utility model relates to a plastic oil pan for a diesel engine, specifically a plastic oil pan with an integrated electric heater. Background Technology

[0002] In cold winter regions, there are instances where diesel engines fail to start due to excessively low temperatures. This is partly because the engine parts contract and deform under low temperatures, altering the gaps between them; and partly because engine oil changes its physical state at temperatures below -20 degrees Celsius, becoming more viscous and potentially leading to slow or absent fuel supply. Prolonged exposure to these low temperatures can cause wear on internal cylinder components, reducing their reliability.

[0003] To prevent the equipment from being in a low-temperature environment for extended periods, electric heating devices are often used. These devices include adhesive electric blankets and threaded electric heating rods. However, these electric heating devices are usually in direct contact with the plastic oil pan. During the heating process, this increases the risk of localized deformation of the plastic oil pan, which can lead to damage and oil leakage. Utility Model Content

[0004] To address the above problems, this utility model provides a plastic oil pan with an integrated electric heater. By placing the electric heater inside an insulating support frame, contact between the heater and the plastic oil pan body is avoided, thus reducing the risk of deformation of the plastic oil pan.

[0005] The technical solution adopted in this utility model is: a plastic oil pan with an integrated electric heater, characterized in that it includes a plastic oil pan body, an insulating support frame, and an electric heater. The electric heater is installed inside the plastic oil pan body via the insulating support frame, and the insulating support frame has an internal mounting cavity. The electric heater is wrapped with insulating glass wool and then installed inside the mounting cavity. Placing the electric heater inside the insulating support frame avoids contact with the plastic oil pan body, reducing the risk of deformation of the plastic oil pan. The outer shell of the insulating support frame is made of aluminum alloy, allowing for long-term contact with engine oil. Furthermore, the insulating support frame has a plate-like structure, increasing the contact area with the engine oil and improving the efficiency of converting electrical energy into heat energy. The insulating glass wool not only prevents electric sparks from leakage from the electric heater from igniting the engine oil but also effectively conducts the heat energy of the electric heater.

[0006] Preferably, the electric heater's wires pass through an aluminum alloy insulated support frame and a guide connector before being electrically connected to the auxiliary battery. The main battery and auxiliary battery are connected via an isolator, and the electric heater is controlled by the auxiliary battery, which can charge it while the vehicle is in motion. If the auxiliary battery is depleted, it will not affect the vehicle starting device controlled by the main battery, and the vehicle can start normally.

[0007] Preferably, the guide joint is fixedly mounted on the plastic oil pan body via a support block. The support block is integrally molded using injection molding and has its own internal thread to ensure a tight connection between the guide joint and the support block. Simultaneously, the support block has a pre-reserved sealing groove, which serves as the sealing mating surface for the rectangular sealing ring, preventing oil leakage from the internal thread of the support block.

[0008] Preferably, one end of the guide joint is connected to the insulating support frame via an external threaded connector, and the other end extends out of the plastic oil pan body through the support block. By setting the guide joint and the support block, an effective connection between the electric heater and the external power source (auxiliary battery) can be achieved.

[0009] Preferably, a rectangular sealing ring is provided between the guide joint and the support block to prevent oil leakage from the internal threads of the support block.

[0010] Preferably, the insulating support frame is positioned below the oil suction pipe, near the oil inlet. This allows for better heat exchange with the oil and improves heat exchange efficiency.

[0011] Preferably, the insulating support frame is arranged perpendicular to the oil suction pipe. This results in a simple and compact structure.

[0012] Preferably, the lugs at both ends of the insulating support frame are fixedly connected to the hexagonal flange nuts pre-embedded on the plastic oil pan body by hexagonal flange bolts, and the connection is tight and reliable.

[0013] Preferably, the electric heater has a built-in thermostat. This allows the driver to control the electric heater from inside the vehicle; the heating temperature and time are pre-set, and the engine oil in the oil pan can be heated simply by operating a switch.

[0014] The beneficial effects of this utility model are as follows: By placing the electric heater inside the insulating support frame, the electric heater is prevented from directly contacting the engine oil, thus eliminating the risk of electric sparks igniting the engine oil; insulating glass wool is installed between the insulating support frame and the electric heater, which can prevent electric sparks caused by leakage of the electric heater from igniting the engine oil, and can also effectively conduct the heat energy of the electric heater; a certain gap is maintained between the insulating support frame and the inner wall of the plastic oil pan body, reducing the damage caused by deformation of the plastic material due to heating; the outer shell of the insulating support frame is made of aluminum alloy material, which can be in contact with the engine oil for a long time, and the insulating support frame adopts a plate structure, which increases the contact area with the engine oil and improves the efficiency of electrical energy conversion into heat energy.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-2 As shown, this utility model discloses an integrated electric heater with a plastic oil pan, comprising a plastic oil pan body 1, an insulating support frame 2, and an electric heater 9. The electric heater 9 is mounted inside the plastic oil pan body 1 via the insulating support frame 2. The insulating support frame 2 is a plate-shaped hollow structure with an internal mounting cavity for mounting the electric heater 9. The electric heater 9 is wrapped with insulating glass wool 10 and then placed inside the mounting cavity of the insulating support frame 2. Placing the electric heater 9 inside the insulating support frame 2 avoids direct contact between the electric heater 9 and the plastic oil pan body 1, reducing the risk of deformation of the plastic oil pan body 1. The outer shell of the insulating support frame 2 is made of aluminum alloy, allowing for long-term contact with engine oil. The plate-shaped structure of the insulating support frame 2 increases the contact area with the engine oil, improving the efficiency of electrical energy conversion to heat energy. The insulating glass wool 10 prevents electrical sparks from the electric heater 9 from igniting the engine oil and effectively conducts the heat energy of the electric heater 9.

[0018] Combination Figure 4-5 As shown, in this embodiment, the wire 91 of the electric heater 9 passes through the aluminum alloy insulating support frame 2 and the guide connector 3 and is electrically connected to the auxiliary battery. The main battery and the auxiliary battery are connected through an isolator. The electric heater 9 is controlled by the auxiliary battery and can be charged while the vehicle is in motion. If the auxiliary battery is depleted, it will not affect the vehicle starting device controlled by the main battery, and the vehicle can start normally.

[0019] Furthermore, the guide joint 3 is fixedly mounted on the plastic oil pan body 1 via the support block 6. The support block 6 and the plastic oil pan body 1 are integrally molded using injection molding. The support block 6 has its own internal thread, which can ensure a tight connection between the guide joint 3 and the support block 6. At the same time, the support block 6 has a pre-reserved sealing groove, which serves as the sealing mating surface for the rectangular sealing ring 5, preventing oil leakage from the internal thread of the support block 6.

[0020] Furthermore, one end of the guide connector 3 is connected to the insulating support frame 2 via an external threaded connector (double-ended) 4, and the other end extends out of the plastic oil pan body 1 through the support block 6. By setting the guide connector 3 and the support block 6, the wire 91 of the electric heater 9 is led out of the plastic oil pan body 1, realizing the effective connection between the electric heater 9 and the external power source (auxiliary battery).

[0021] In this embodiment, the insulating support frame 2 is located below the oil suction pipe 11, near the oil suction port. The oil flows faster at the oil suction port, and placing the electric heater 9 here allows for better heat exchange with the oil, thus improving heat exchange efficiency.

[0022] Combination Figure 3 As shown, the insulating support frame 2 is vertically positioned relative to the oil suction pipe 11. Two support columns 15 are installed on the plastic oil pan body 1, directly below the lifting lugs at both ends of the insulating support frame 2. The support columns 15 and the plastic oil pan body 1 are made of the same material, plastic, and are integrally injection molded. Hexagonal flange nuts 7 are pre-embedded within the support columns 15 to enhance material rigidity. During installation, hexagonal flange bolts 8 are passed through the lifting lug holes at both ends of the insulating support frame 2 and threadedly connected to the pre-embedded hexagonal flange nuts 7 within the support columns 15. The connection is secure and reliable.

[0023] In this embodiment, the electric heater 9 is equipped with a thermostat, which can maintain a constant temperature and prevent overheating from causing failure of the sealed connection, while ensuring the power supply capacity of the battery.

[0024] This utility model features an integrated electric heater with a plastic oil pan, allowing the driver to control the heater from inside the vehicle. The heating temperature and time are pre-set; simply operating a switch heats the engine oil in the oil pan. This enhances the driver's experience while reducing engine component maintenance costs.
