Description

Technical Field

[0001] The present invention relates to the technical field of engines, and in particular to a crankcase reinforcement plate device. Background Art

[0002] The engine crankcase is the core structure at the bottom of the cylinder block for installing the crankshaft. It is the load-bearing and sealing component of the engine. The crankcase consists of an upper crankcase and a lower crankcase. The upper crankcase and the cylinder are cast as one piece, and the lower crankcase is stamped from thin steel plates or cast from aluminum alloy. An oil stabilizing baffle is installed inside to suppress oil shock. The lower crankcase is a removable sealed shell located at the bottom of the engine and is a core component of the lubrication system.

[0003] On steep slopes (whether ascending or descending a steep slope), the vehicle will tilt significantly. At this point, gravity forces the oil in the engine oil pan to flow and collect in the direction of the tilt (backward when ascending, forward when descending). The oil pump's suction port is typically located at the bottom center of the oil pan or slightly to the rear. When the vehicle's tilt is too steep, the oil that originally covered the suction port will flow to the low-lying area of ​​the oil pan, exposing the suction port to the air. As the oil pump continues to operate, it will begin to draw in a mixture of air and oil (foam) or even pure air, causing the oil pressure to drop sharply or return to zero. This prevents the internal engine parts from being lubricated promptly, and in severe cases, can lead to a lavalier failure, making the engine susceptible to mechanical failure. Summary of the Invention

[0004] The object of the present invention is to provide a crankcase reinforcement plate device to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solution: comprising a reinforcing plate, wherein a plurality of lower grooves are provided on the reinforcing plate, and an oil return hole is provided at the center of each of the lower grooves;

[0006] It also includes avoidance surfaces arranged on both sides of the oil return hole for motion envelope avoidance.

[0007] As a further description of the above technical solution:

[0008] Both sides of the lower groove are configured to be bowl-shaped, so as to guide the oil to flow back when the reinforcing plate is tilted.

[0009] As a further description of the above technical solution:

[0010] When the reinforcing plate is tilted, the bowl shape of the lower groove is configured to form a small oil pool.

[0011] As a further description of the above technical solution:

[0012] A guide groove is provided in the lower groove so that the splashed oil or the refluxed oil can return to the small oil pool when the reinforcing plate is tilted.

[0013] As a further description of the above technical solution:

[0014] The invention also includes a plurality of connecting pipes slidably arranged in each lower groove, and an offset component for driving the pipe openings of the connecting pipes to deflect, so that the pipe openings of the connecting pipes are always immersed in the oil.

[0015] As a further description of the above technical solution:

[0016] The offset assembly includes a pull rope fixed to one side of the connecting pipe, and the pull rope extends to the other side of the connecting pipe and is fixedly connected to the reinforcing plate.

[0020] A plurality of guide grooves are formed on the reinforcing plate, and a guide rod extending into the guide groove is fixedly connected to the bottom of the annular plate.

[0021] In the above technical solution, the crankcase reinforcement plate device provided by the present invention has the following beneficial effects:

[0022] The present invention improves the strength of the crankcase by arranging a reinforcing plate, and arranges a lower groove. When the vehicle tilts, part of the engine oil remains in the lower groove, ensuring that the oil pump stably pumps oil to lubricate engine parts, and can also prevent the engine oil from being lost, effectively preventing this part of the engine oil from flowing out of the oil suction port area too quickly and excessively, and "trapping" a part of the engine oil near the oil suction port to maintain the lowest oil level. Even if the vehicle tilts, the area surrounded by the reinforcing plate has a blocking effect, and the oil level therein drops much more slowly than other areas of the oil pan. The reinforcing plate can also be used for damping and separation, reducing the overall shaking amplitude and splashing height of the oil in the oil pan; keeping the oil level in the oil suction port area relatively stable to prevent air from mixing into the engine oil to form foam.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] See also Figure 1-Figure 5The present embodiment provides a crankcase reinforcement plate device, comprising a reinforcement plate 1, wherein the reinforcement plate 1 is provided with a plurality of lower grooves 11, each of which has an oil return hole 12 at its center; and avoidance surfaces 13 provided on both sides of the oil return hole 12 for motion envelope avoidance. The reinforcement plate 1 is provided to improve the strength of the crankcase. The lower grooves 11 are provided so that when the vehicle tilts, some engine oil remains in the lower grooves 11, ensuring that the oil pump stably pumps oil into the engine parts for lubrication. The device also prevents oil loss, effectively preventing this part of the engine oil from flowing out of the oil suction port area too quickly and excessively, and "traps" some of the engine oil near the oil suction port to maintain the minimum oil level. Even if the vehicle tilts, the oil level in the area enclosed by the reinforcement plate 1 drops much more slowly than in other areas of the oil pan due to the blocking effect. The reinforcement plate 1 can also serve as a damper and separator, reducing the overall sloshing amplitude and splash height of the oil in the oil pan; maintaining the relative stability of the oil level in the oil suction port area to prevent air from mixing with the oil and forming foam.

[0035] In an embodiment further provided by the present invention, the two sides of the lower groove 11 are arranged in a bowl shape, which is used to guide the oil backflow when the reinforcing plate 1 is tilted. The reinforcing plate 1 is designed to have a slope or a specific guide groove structure, which can more effectively guide the splashing oil or the returning oil to return to the "small oil pool" near the oil suction port first, thereby accelerating the recovery of the oil amount in the oil suction port area.

[0036] Furthermore, when the reinforcement plate 1 is tilted, the bowl-shaped lower groove 11 forms a small oil pool, creating a localized, deeper "oil pool" for the oil intake. As long as the tilt angle is within the design's allowable range (for example, increasing from 30 degrees to 40 degrees), this "oil pool" ensures the oil intake is always submerged in oil, preventing air from being drawn in.

[0037] Furthermore, a guide groove is provided in the lower groove 11, so that the splashed oil or refluxed oil returns to the small oil pool near the oil suction port when the reinforcing plate 1 is tilted, thereby accelerating the recovery of the oil volume in the oil suction port area.

[0038] In an embodiment further provided by the present invention, it also includes a plurality of connecting pipes 2 slidably arranged in each lower groove 11, and the bottom middle section of the connecting pipe 2 is configured as a retractable pipe mouth. When the reinforcing plate 1 rotates, the pipe mouth can be adaptively adjusted, and an offset component is used to drive the pipe mouth of the connecting pipe 2 to deflect, so that the pipe mouth of the connecting pipe is always immersed in the oil. When the engine tilts, the reinforcing plate 1 tilts synchronously, and the offset component is used to drive the connecting pipe 2 to move toward the tilted side, and at the same time, the pipe mouth of the connecting pipe 2 is driven to rotate toward the tilted side, ensuring that the pipe mouth is always immersed in the oil, thereby ensuring lubrication of the internal parts of the engine.

[0039] In the embodiment provided by the present invention, the offset assembly includes a pull rope 32 fixed to one side of the connecting pipe 2 , and the pull rope 32 extends to the other side of the connecting pipe 2 and is fixedly connected to the reinforcing plate 1 .

[0040] Specifically, the connecting pipe 2 is fixedly connected to an annular plate 31, and a plurality of guide rings 33 are provided at the bottom of the fixing plate. The pull ropes 32 pass through the guide rings 33 on the same side in sequence. Figure 5 As shown), by providing a guide ring 33, the pulling direction of the pull rope 32 is controlled so that when the pull rope 32 is pulled, the connecting pipe only rotates along the tilting direction of the reinforcing plate 1.

[0041] In the solution further provided by the present invention, a plurality of guide grooves are provided on the reinforcing plate 1, and a guide rod 34 extending into the guide groove is fixedly connected to the bottom of the annular plate 31. The guide groove is arranged in an inverted V shape, and the angle of the inclined surface is small. When the reinforcing plate 1 tilts, the guide rod 34 is ensured to move in the guide groove along the tilt direction of the reinforcing plate 1, and when the reinforcing plate 1 rotates to a horizontal state, the guide rod 34 automatically resets to the center.

[0042] When in use, the reinforcement plate 1 is bolted to the oil pan or the bottom of the engine body, located around the oil suction head (filter) of the oil suction pipe. The connecting pipe 2 is connected to the oil suction pipe of the oil pump. When the vehicle goes uphill or downhill, the engine will tilt, causing the oil in the oil pan to flow to one side, and the reinforcement plate 1 will tilt to one side at the same time.

[0043] Part of the engine oil will remain in the lower groove 11 on one side. When the reinforcing plate 1 is tilted, the guide rod 34 slides in the guide groove, driving the connecting pipe 2 to slide toward the tilted side.

[0044] When the connecting pipe 2 slides, since one end of the pull rope 32 is fixed, the connecting pipe 2 on the inclined side is pulled, causing the side of the connecting pipe 2 close to the inclined direction to be compressed, while the other side is stretched, so that the oil outlet of the connecting pipe is aligned with the small oil pool and immersed in the oil.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
