[0006] This utility model relates to an oil pan for an automotive engine assembly, comprising:

[0007] An oil pan, comprising a main body, a mounting plate, and a sealing gasket, wherein the mounting plate is fixed to the top of the main body, and the sealing gasket is fixed to the mounting plate;

[0008] The anti-damage component includes an anti-collision ring, a first groove, a first spring, a support plate, and a shock-absorbing pad. The anti-collision ring is wrapped around the four sides of the lower end of the main body. The first groove is opened at the lower end of the anti-collision ring. One end of the first spring is fixed to the top of the first groove. The support plate is fixed to the lower end of the first spring. The shock-absorbing pad is fixed to the lower end of the support plate.

[0009] Furthermore, the damage prevention component also includes a connecting pipe and a countersunk hole. The connecting pipe is welded to the lower ends of both sides of the main body, and the countersunk hole is opened on both sides of the anti-collision ring. The connecting pipe is inserted into the countersunk hole and fixed by screws.

[0010] Furthermore, the damage protection component also includes a slot, which is formed on the upper side of the anti-collision ring.

[0011] Furthermore, the oil pan also includes an oil drain pipe and a mounting hole. The oil drain pipe is fixed to the lower side of the main body and is snapped into the groove. The mounting hole is opened on the sealing gasket.

[0012] Furthermore, the outer edges of the support plate and the shock-absorbing pad match the outer edge of the lower end of the anti-collision ring.

[0013] Furthermore, it also includes a leak-proof component, which includes an edge, a connecting plate, and an outer ring edge.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the setting of anti-damage components, wraps the anti-collision ring around the lower end of the main body, allowing the connecting pipe to be inserted into the countersunk hole, and the screw passes through the countersunk hole and is fixed to the connecting pipe. When the lower end of the oil pan is impacted, it first collides with the shock-absorbing pad under the support plate, causing the first spring to be compressed. The shock-absorbing pad and the first spring absorb part of the vibration, and then the anti-collision ring absorbs part of the vibration. This setting can reduce the impact of external forces on the lower end of the oil pan main body and reduce the frequency of damage to the main body.

[0017] II. In this utility model, the sealing gasket is placed on the mounting plate by setting a leak-proof component, so that the connecting plate and the outer ring edge are locked on the edge. Then, the mounting plate is fixed to the lower end of the crankcase with bolts and tightened. As the car is used, the oil pan and the sealing gasket deform, and the connection of the mounting plate becomes loose. At this time, the second spring in the second groove extends, causing the sealing gasket to fit against the lower end of the crankcase. This setting can improve the sealing performance of the mounting plate connection and reduce the risk of oil leakage. Attached Figure Description
