[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-5 The engine lower oil pan shown in the figure is resistant to high temperature and corrosion, comprising an oil pan cover body 1, a plurality of mounting edges 2 are fixedly connected to the side of the top of the oil pan cover body 1, an oil filling hole 3 is arranged in the middle of the bottom end of the oil pan cover body 1, a main oil plug 301 is sleeved inside the oil filling hole 3, and the main oil plug 301 is used to block the oil filling hole 3, and an oil outlet end surface 101 is arranged on one side inside the oil pan cover body 1, and the oil outlet end surface 101 is used to drain the oil body;

[0022] It should be noted that the designed oil pan cover body 1 is made of high-temperature resistant and corrosion-resistant material to prevent the oil inside the engine from burning, causing the coating to corrode and fall off inside the oil pan cover body 1, and the corroded coating to flow into the filter and clog it, affecting its normal use. The use of high-temperature resistant and corrosion-resistant material can effectively protect the interior from erosion and support the normal use of the engine.

[0023] Specifically, a sealing groove 201 is opened around the top of the mounting edge 2, and the sealing groove 201 is used to install a sealing ring. Threaded holes 202 are opened at the top of the mounting edge 2 and the side of the top of the oil pan cover body 1. An auxiliary oil groove 4 is set on the other side of the inside of the mounting edge 2. The auxiliary oil plug 401 is sleeved on the middle part of the bottom end of the auxiliary oil groove 4, and the auxiliary oil plug 401 is used to seal the auxiliary oil groove 4.

[0024] It should be noted that the designed sealing groove 201 is used to place the sealing ring. When the sealing ring is tightened with screws, the engine and the oil pan cover body 1 press the sealing ring against each other, so that the sealing ring effectively seals the oil pan cover body 1 to prevent oil leakage. Long-term installation of the sealing gasket will lead to difficulty in disassembly. The designed auxiliary oil groove 4 can facilitate the disassembly of the oil pan cover body 1.

[0025] Specifically, a threaded main oil cap 303 is fixedly connected to the middle of the bottom end of the main oil plug 301, and a threaded structure 302 is provided at the bottom end of the outer wall of the oil filling hole 3. The inner wall thread of the threaded main oil cap 303 is threadedly matched with the threaded structure 302. The threaded main oil cap 303 is used to push the main oil plug 301 to block the oil filling hole 3 through threaded matching.

[0026] It should be noted that the designed main oil plug 301 is in the form of a piston and is tightly plugged into the inner wall of the oil filling hole 3. The main oil plug 301 and the threaded main oil cover 303 are an integrated component. The thread on the inner wall of the threaded main oil cover 303 is threadedly matched with the threaded structure 302 at the bottom end of the outer wall of the oil filling hole 3, and the main oil plug 301 is fixed. When installing, first insert the main oil plug 301 into the inner wall of the oil filling hole 3, and use the threaded main oil cover 303 and the threaded structure 302 to twist each other to push the main oil plug 301 tightly to complete the installation.

[0027] Specifically, a strip texture 103 is provided on the top of the oil outlet end surface 101, and the strip texture 103 is used to guide the oil to flow into the oil filling hole 3. An oil storage tank 102 is provided at the bottom of the oil outlet end surface 101 and on the side of the oil filling hole 3. The oil storage tank 102 is used to precipitate and cool the oil. The bottom ends of multiple mounting edges 2 are all provided with a convex plate structure that exceeds the bottom edge of the oil bottom cover body 1, and the convex plate structure is used to guide the assembly of the lower oil pan.

[0028] It should be noted that the designed oil outlet end face 101 and the oil filling hole 3 are located at the same horizontal plane, and its main purpose is to facilitate drainage and control of oil volume. The texture trend of the strip texture 103 designed on the surface tends to the oil filling hole 3. When the oil flows into the oil outlet end face 101, the strip texture 103 guides the oil to flow to the oil filling hole 3, which is convenient for disassembly to draw out all the oil. The designed oil storage tank 102 is located at the oil filling hole 3. Its main purpose is to store the oil in the oil storage tank 102, and then enter the filter element for use after cooling and precipitating impurities.

[0029] Working principle of this utility model:

[0030] When installing the designed lower oil pan, align the installation position between the installation edge 2 and the quasi-threaded hole 202, and use screws to connect the engine and the oil pan cover body 1. The oil pan cover body 1 is made of high temperature resistant and corrosion resistant materials to protect the interior and prevent internal damage. The bottom end of the middle oil filling hole 3 is sleeved with a threaded main oil cap 303. When the threaded main oil cap 303 is sleeved, the main oil plug 301 in the middle of the top will be tightly sleeved on the inner wall of the oil filling hole 3 to block the oil filling hole 3. The inner wall of the threaded main oil cap 303 is threadedly matched with the threaded structure 302 at the bottom end of the outer wall of the oil filling hole 3 to block the bottom hole of the oil filling hole 3 and push the main oil plug 301 to tightly plug the oil filling hole 3. When draining the oil, loosen the threaded main oil cap 303 and pull out the main oil plug 301. The oil above the oil outlet end surface 101 will flow to the oil filling hole 3 along the route of the strip texture 103.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
