Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle engine cases, and particularly relates to a case and a motorcycle engine. Background Art

[0002] The engine used in a motorcycle is an internal combustion engine, which utilizes the expansion work of fuel combustion in a limited space. The realization method is that the mixed gas generated by the mixture of fuel and air is ignited by a spark plug and then burns and expands to generate heat energy. The gas expands when heated, and is converted into mechanical energy through a mechanical device to compress and release the gas to do work externally.

[0003] In order to fix the components of the engine, some shells adapted to the components are usually used to fix both sides of the engine.

[0004] However, after the components of the engine are fixed, a protective shell is usually installed to provide a protective effect for the engine. However, the multi-layer reinforcement and protection will cause the heat generated by the engine not to be dissipated in time, resulting in a large accumulation of heat, which is then transferred to the outer shell. If a person touches it, burns will occur. Summary of the Utility Model

[0028] The following describes a box body and a motorcycle engine according to an embodiment of the present utility model with reference to the drawings.

[0029] The present utility model aims to provide an embodiment of a motorcycle engine. Specifically, with reference to Figures 1-3, the present utility model aims to provide an embodiment of a housing of a motorcycle engine. The housing of this embodiment mainly includes a housing 100 and a delivery pipe 130 disposed inside the housing 100. The delivery pipe 130 is arranged to gradually narrow from a wider end. A wind inlet hopper 110 is fixedly installed at the wider end of the delivery pipe 130, and the other end of the delivery pipe 130 communicates with the inside of the housing 100.

[0030] In some specific embodiments of the present utility model, the flowing air contacted by the vehicle body during movement can be inhaled through the delivery pipe 130. Thus, the air is delivered to the inside of the housing 100 to cool the components inside the housing 100.

[0031] In some specific embodiments of the present utility model, the wider end of the delivery pipe 130 can be positioned closer to the air inlet to increase the air intake volume. At the same time, the gradually narrowing inner diameter of the delivery pipe 130 can increase the air flow velocity.

[0032] Reference Figure 1 , in some specific embodiments of the present utility model, a muffler 140 can be fixedly installed at the end of the delivery pipe 130 away from the wind inlet hopper 110. The muffler 140 is used for wind whistle noise reduction, and an internal thread 180 is provided inside the wind inlet hopper 110.

[0033] In some specific embodiments of the present utility model, a wind inlet hopper 110 can be provided at one end of the delivery pipe 130 to significantly increase the air intake volume.

[0034] In some specific embodiments of the present utility model, the internal thread 180 can be used to increase the air flow travel distance, thereby increasing the air movement speed.

[0035] In some specific embodiments of the present utility model, a muffler 140 can be provided at the other end of the delivery pipe 130 to maximally eliminate the wind whistle sound when the air enters the inside of the housing 100.

[0036] In summary, first, through the delivery pipe 130 in this embodiment, external air can be delivered to the inside of the housing 100 to air-cool the devices inside the housing 100.

[0037] Secondly, by providing a wind inlet hopper 110 at one end of the delivery pipe 130, the air intake volume of the delivery pipe 130 can be increased. At the same time, the internal thread 180 provided inside the wind inlet hopper 110 can increase the air flow rate, thereby enhancing the heat dissipation effect.

[0038] Furthermore, by using the muffler 140, the wind whistle sound generated at the outlet can be maximally eliminated to achieve a silent effect.

[0039] Reference Figure 2, in some specific embodiments of the present utility model, both ends of the conveying pipe 130 can be communicated with the air inlet hopper 110 and the silencer 140. One end of the air inlet hopper 110 extends to the outside of the housing 100, and the opening position of the other end of the air inlet hopper 110 faces downward.

[0040] It is easy to understand that in this embodiment, by communicating the conveying pipe 130 with the air inlet hopper 110 and the silencer 140, air can smoothly enter the interior of the housing 100 through the conveying pipe 130 and the silencer 140 to dissipate heat from the components inside the housing 100.

[0041] In some specific embodiments of the present utility model, a limiting pipe 120 for limiting and fixing the conveying pipe 130 can be provided inside the housing 100. The limiting pipe 120 is opened from wide to narrow and is adapted to the conveying pipe 130.

[0042] Reference Figure 1 , it is easy to understand that in this embodiment, by providing the limiting pipe 120 inside the housing 100 and the path of the limiting pipe 120 from wide to narrow being the same as that of the conveying pipe 130, the conveying pipe 130 can be completely installed inside the limiting pipe 120, thereby completing the position fixing of the conveying pipe 130.

[0043] In some specific embodiments of the present utility model, a crankshaft rotation groove 200 for limiting the rotation of the crankshaft can be provided inside the housing 100, and the limiting pipe 120 is provided on one side of the crankshaft rotation groove 200.

[0044] It is easy to understand that in this embodiment, by setting the limiting pipe 120 as a semi-circular arc and arranging it near the outside of the housing 100, it can be avoided that after the conveying pipe 130 is installed, the rotation of the original crankshaft and the main and auxiliary shafts is affected.

[0045] In some specific embodiments of the present utility model, a reinforcing rib path 170 can be fixedly provided inside the housing 100. A plurality of positioning holes 150 are provided on the reinforcing rib path 170 for positioning and connecting the left and right boxes. A plurality of threaded installation grooves 160 are provided on the periphery of the housing 100 for connecting and fastening the left and right boxes.

[0046] It is easy to understand that in this embodiment, the strength of the housing 100 can be increased through the reinforcing rib path 170, and at the same time, a sealing ring can be added on its outside to increase the sealing performance of the housing 100. At the same time, the positioning holes 150 can enable the staff to first position the connection between the boxes through the positioning pins when installing the left and right boxes, avoiding deviation during subsequent screw fixation.

[0047] Secondly, the threaded mounting groove 160 provided on the peripheral side of the housing 100 enables the left and right boxes to be fixedly connected by screwing through the addition of fastening bolts.

[0048] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0049] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
