Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle engines, in particular to a housing structure of a motorcycle engine. Background Art

[0002] A motorcycle is a lightweight means of transportation that usually uses a gasoline engine, a diesel engine, and an electric motor as its main power source. Gasoline engines and diesel engines are both internal combustion engines, and the engine casing is mainly used to hold engine oil, protect structures, and install structures.

[0003] The application number is 202023058127.9, which is a motorcycle engine housing structure, including a side housing, a crankshaft hole, an intermediate block, a convex sleeve, a countershaft hole, a limiting protrusion, a mounting hole, an observation window, a screw hole, a box wall, a first rib plate, a second rib plate, an anti-corrosion coating, a sound-absorbing cotton layer and an outer shell. The beneficial effects of the utility model are as follows: the observation window is transparent, so that the internal working state can be clearly observed; two limiting protrusions are provided, so that the relative displacement of the corresponding shafts can be reduced during operation, which greatly reduces wear; the crankshaft hole and the countershaft hole are both machined on the semi-finished product after die-casting, so that the machined crankshaft hole and countershaft hole have higher precision; the interior of the sound-absorbing cotton layer is provided with rigid filling, so as to improve the sound insulation effect of the side housing; the outer ring of the box wall is provided with a plurality of connecting ears for fixing the side housing, and the mounting holes are respectively provided on the connecting ears, so as to facilitate the installation and disassembly between the side housings.

[0004] This technical solution facilitates observation of the oil level by providing a tempered glass window, but the oil will become dirty after being used for too long, and there will be some impurities such as metal debris inside, which will cause the tempered glass window to be easily covered by the oil stains, thereby affecting the observation of the oil level. Secondly, tempered glass is not indestructible, and when a motorcycle is running on the road for a long time, some flying gravel and sand can easily block the tempered glass or even cause long-term impact to cause the tempered glass to break. Secondly, the engine will generate a lot of heat when it is working, and when it stops, the temperature will drop rapidly due to the material and the setting of the cylinder cooling fins. After long-term use, the tempered glass is prone to bursting due to the influence of thermal expansion and contraction, which will cause oil leakage to pollute the environment or external dust and rainwater to enter the engine and affect the engine life. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a motorcycle engine housing structure to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a motorcycle engine casing structure, including an engine casing main body, a shell connected to one side of the top of the engine casing main body, a limit ring fixed at the lower part of the shell, a float bag is arranged inside the shell, and a magnetic ring is installed inside the float bag, a scale groove is opened on one side of the shell, a pointer passes through the lower part of one side of the shell, and a linkage seat is fixed on one side of the pointer.

[0007] By adopting the above technical solution, the outer shell is connected with the engine shell body. When the engine oil is loaded into the engine shell body, the engine oil will also enter the inner part of the outer shell. At this time, the float bag floats on the oil level and moves upward with the rise of the oil level. The floating of the float bag drives the magnetic ring to float upward. At this time, the magnetic ring attracts the linkage seat through magnetic attraction, so that the linkage seat and the pointer float up. The oil level is convenient to check by cooperating with the pointer and the scale groove. There is no need to rely on experience or plug and unplug the oil dipstick for checking. The operation is simple, convenient and time-saving. When the oil is discharged, the float bag moves downward with the drop of the oil level. Then the float bag is limited by the limit ring to prevent the float bag from blocking the passage for the oil to enter the outer shell, making it difficult for the oil to enter the outer shell later.

[0008] Furthermore, the linkage seat is made of medium carbon steel, and the linkage seat and the pointer are both slidably connected to the housing.

[0009] By adopting the above technical solution, the magnetic ring attracts the linkage seat through magnetic attraction, so that the linkage seat and the pointer float up, and the oil level is convenient to check through the cooperation between the pointer and the scale groove.

[0010] Furthermore, the float bag is slidably connected to the shell, and the float bag abuts against the limit ring.

[0011] By adopting the above technical solution, when the engine oil is discharged, the float moves downward as the oil level drops, and then the float is limited by the limit ring to prevent the float from blocking the channel for the engine oil to enter the housing, making it difficult for the engine oil to enter the housing later.

[0012] Furthermore, a cylinder block is fixed on the other upper side of the engine casing body, a casing cover is connected to the outer surface of the engine casing body, and crankshaft holes are provided on the outer surface of the casing cover and the back of the engine casing body.

[0013] By adopting the above technical solution, the arrangement of the cylinder body makes it easy to install and protect the piston, the arrangement of the shell cover and the engine shell body makes it easy to store engine oil and protect the crankshaft and connecting rod, and the arrangement of the crankshaft hole makes it easy for the crankshaft to pass through.

[0014] Furthermore, a bolt passes through the top of the shell, and a sealing gasket is arranged between the bolt and the shell, a groove is opened at the bottom end of the bolt, and a hook is connected to the top of the float bag.

[0015] By adopting the above technical solution, after the engine oil is drained, the staff can remove the bolts and the sealing gasket, and take out the float bag by hooking the hook, or take out the float bag by metal that can be adsorbed by a magnet or by using a magnet, so as to clean the metal debris adsorbed on the bottom of the float bag. After cleaning, the staff put the float bag and the sealing gasket back and tighten the bolts.

[0016] Furthermore, the diameter and height of the groove are greater than the length, width and height of the hook.

[0017] By adopting the above technical solution, the hook enters the groove after the float bag floats up, so as to prevent the bolt from pressing against the hook and making the float bag unable to continue to float up.

[0018] Furthermore, the bolt is threadedly connected to the housing, and the bolt abuts against the sealing gasket.

[0019] By adopting the above technical solution, after cleaning, the staff will put the float bag and the sealing gasket back and tighten the bolts. The setting of the sealing gasket prevents the oil from leaking from the gap between the outer casing and the bolts.

[0020] Furthermore, the sealing gasket is made of fluororubber material.

[0021] By adopting the above technical solution, the setting of the sealing gasket prevents the oil from leaking from the gap between the housing and the bolt, and the fluororubber has good oil resistance and is not easily affected by the oil.

[0022] Furthermore, a slide groove is provided on the inner wall of the shell, a slide block is fixed on the outer surface and the back of the linkage seat, and balls are passed through both sides of the slide block.

[0023] By adopting the above technical solution, when the linkage seat slides up and down, the slider and the slide groove are used for guidance to prevent the linkage seat and the pointer from being offset and falling off. At the same time, the rolling of the ball reduces the wear between the slider and the slide groove, thereby extending the service life of the structure.

[0024] Furthermore, the ball bearing is rollingly connected to the slider, and the slider is slidingly connected to the slide groove via the ball bearing.

[0025] By adopting the above technical solution, the wear between the slider and the slide groove is reduced by the rolling of the ball, thereby extending the service life of the structure.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is connected with the engine case body through the arrangement of the shell, the pointer, the scale groove, the limit ring, the float bag, the magnetic ring and the linkage seat. When the engine oil is loaded into the engine case body, the engine oil will also enter the shell. At this time, the float bag floats on the liquid level of the engine oil and moves upward with the rise of the engine oil level. The floating of the float bag drives the magnetic ring to float upward. At this time, the magnetic ring attracts the linkage seat through magnetic attraction, so that the linkage seat and the pointer float up. The oil level is convenient to check through the cooperation of the pointer and the scale groove, and there is no need to rely on experience or plug and unplug the oil dipstick for checking. The operation is simple, convenient, time-saving and labor-saving. When the engine oil is discharged, the float bag moves downward with the drop of the oil level, and then the float bag is limited by the limit ring to prevent the float bag from blocking the passage for the engine oil to enter the shell, making it difficult for the engine oil to enter the shell later. The engine oil level in the engine can be checked without using transparent materials, and the structure is stable and safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0036] The following describes an embodiment of the utility model based on its overall structure.

[0037] Embodiment 1:

[0038] A motorcycle engine housing structure, such as Figure 1-Figure 6 As shown, it includes an engine casing body 1, a shell 5 is connected to one side of the top of the engine casing body 1, and the shell 5 is communicated with the engine casing body 1. When the maintenance staff fills the engine oil into the engine casing body 1, the engine oil will also enter the shell 5; a limiting ring 10 is fixed at the lower part of the shell 5, and a floating bag 11 is arranged inside the shell 5. The floating bag 11 is slidably connected with the shell 5, and the floating bag 11 abuts against the limiting ring 10. The floating bag 11 is limited by the limiting ring 10 to prevent the floating bag 11 from moving down and blocking the passage for the engine oil to enter the shell 5, making it difficult for the engine oil to enter the shell 5; A magnetic ring 12 is installed inside the float 11, a scale groove 9 is opened on one side of the shell 5, and a pointer 8 runs through the lower side of the shell 5. The pointer 8 cooperates with the scale groove 9 to facilitate the staff to check the oil level without relying on experience or plugging and unplugging the oil dipstick for checking; a linkage seat 15 is fixed on one side of the pointer 8, and the linkage seat 15 is made of medium carbon steel material. The linkage seat 15 and the pointer 8 are both slidably connected to the shell 5. The floating of the float 11 drives the magnetic ring 12 to float up. At this time, the magnetic ring 12 attracts the linkage seat 15 through magnetic attraction, so that the linkage seat 15 and the pointer 8 float up.

[0039] See also Figure 1 and Figure 2 In the above embodiment, a cylinder block 3 is fixed on the other side of the engine casing body 1, a casing cover 2 is connected to the outer surface of the engine casing body 1, and crankshaft holes 4 are provided on the outer surface of the casing cover 2 and the back of the engine casing body 1, which are convenient for installing and protecting the engine crankshaft, piston, connecting rod and other structures.

[0040] Embodiment 2:

[0041] On the basis of the above-mentioned embodiment 1, although the oil level in the engine can be checked without using transparent materials by setting the housing 5, the pointer 8, the scale groove 9, the limit ring 10, the float 11, the magnetic ring 12 and the linkage seat 15, the structure is stable and safe; but the magnetic attraction of the magnetic ring 12 easily absorbs metal debris, and the float 11 is located inside the housing 5 and is difficult to remove and clean, resulting in easy accumulation of metal debris; now by setting the bolt 6, the sealing gasket 7, the hook 13 and the groove 14, it is possible to facilitate the cleaning of the metal debris that remains on the surface of the float 11 due to the magnetic attraction of the magnetic ring 12.

[0042] See also Figure 1 , Figure 3 , Figure 4 and Figure 5In the above embodiment, a bolt 6 is passed through the top of the housing 5, and the bolt 6 is threadedly connected to the housing 5 to facilitate the removal of the float 11; a sealing gasket 7 is arranged between the bolt 6 and the housing 5, and the bolt 6 abuts against the sealing gasket 7. The sealing gasket 7 is made of fluororubber material to prevent the oil from leaking from the gap between the housing 5 and the bolt 6; a groove 14 is opened at the bottom end of the bolt 6, and a hook 13 is connected to the top of the float 11. The float 11 is taken out by hooking the hook 13, or the float 11 is taken out by metal that can be adsorbed by a magnet or by using a magnet, so as to clean the metal debris adsorbed at the bottom of the float 11; the diameter and height of the groove 14 are greater than the length, width and height of the hook 13. After the float 11 floats, the hook 13 enters the inside of the groove 14 to prevent the bolt 6 from abutting against the hook 13 so that the float 11 cannot continue to float.

[0043] Embodiment three:

[0044] On the basis of the above-mentioned embodiment 1, although by setting the outer shell 5, pointer 8, scale groove 9, limit ring 10, float 11, magnetic ring 12 and linkage seat 15, the oil level in the engine can be checked without using transparent materials, and the structure is stable and safe; but the linkage seat 15 is attached to the inner wall of the outer shell 5 due to the influence of magnetic attraction, and the friction force is increased, causing the linkage seat 15 to be easily worn; now by setting the slide groove 16, the slider 17 and the ball 18, the wear can be reduced and the service life of the structure can be extended.

[0045] See also Figure 4-Figure 6 In the above embodiment, a slide groove 16 is provided on the inner wall of the housing 5, and sliders 17 are fixed to the outer surface and the back of the linkage seat 15. Balls 18 are passed through both sides of the slider 17. The balls 18 are rollingly connected to the slider 17. The slider 17 is slidingly connected to the slide groove 16 through the balls 18. The rolling of the balls 18 reduces the wear between the slider 17 and the slide groove 16, thereby extending the service life of the structure.

[0046] The implementation principle of the utility model is as follows: first, the housing 5 is connected with the engine housing body 1. When the maintenance staff fills the engine oil into the engine housing body 1, the engine oil will also enter the housing 5. At this time, the float 11 floats on the oil level and moves upward with the rise of the oil level. The float 11 floats up and drives the magnetic ring 12 to float up. At this time, the magnetic ring 12 attracts the linkage seat 15 through magnetic attraction, so that the linkage seat 15 and the pointer 8 float up. The pointer 8 cooperates with the scale groove 9 to facilitate the staff to check the oil level. There is no need to rely on experience or plug and unplug the oil dipstick for checking. The operation is simple, convenient, time-saving and labor-saving. After the float 11 floats up, the hook 13 enters the groove 14 to prevent the bolt 6 from pressing against the hook 13 so that the float 11 cannot continue to float up.

[0047] When the linkage seat 15 slides up and down, the slider 17 and the slide groove 16 are used for guidance to prevent the linkage seat 15 and the pointer 8 from being offset or falling off. At the same time, the rolling of the ball 18 reduces the wear between the slider 17 and the slide groove 16, thereby extending the service life of the structure;

[0048] When the engine oil is discharged, the float 11 moves downward as the oil level drops, and then the float 11 is limited by the limit ring 10 to prevent the float 11 from blocking the passage for the engine oil to enter the housing 5, making it difficult for the engine oil to enter the housing 5 later. After the engine oil is discharged, the staff can remove the bolt 6 and the sealing gasket 7, and take out the float 11 by hooking the hook 13, or take out the float 11 through metal that can be adsorbed by a magnet or using a magnet, so as to clean the metal debris adsorbed on the bottom of the float 11. After cleaning, the staff put the float 11 and the sealing gasket 7 back and tighten the bolt 6.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
