Embodiment 1

[0032] Such as Figure 1 to Figure 3 as well as Figure 8As shown, a two-cylinder horizontally opposed engine provided in this embodiment includes a cylinder body 1 and a crankshaft 2; the cylinder body 1 includes a first cylinder 101 and a second cylinder 102, and the first cylinder 101 and the second cylinder The two cylinder blocks 102 are connected horizontally. The first cylinder body 101 is provided with a first casing 103, and the first casing 103 is provided with a first channel 104 that runs through it horizontally; the second cylinder body 102 is provided with a second casing 105, and the second casing 105 There is a second channel 106 extending transversely. Both ends of the crankshaft 2 are rotatably connected to the junction of the first cylinder body 101 and the second cylinder body 102 . The crankshaft 2 is provided with a first transmission gear 201 and a second transmission gear 202. The first transmission gear 201 and the second transmission gear 202 are l...

Embodiment 2

[0037] Such as Figure 4 and Figure 5 As shown, the components included in this embodiment and their connections are basically the same as in Embodiment 1, the difference is that the first connecting rod 203 and the second connecting rod 204 are rotatably connected to the crankshaft 2, and the first connecting rod 203 is provided with The first chisel 205 is arranged, the second connecting rod 204 is provided with a second chisel 206; the first cylinder 101 is provided with a first half oil storage chamber 112 on the side of the second cylinder, and the second cylinder 102 is A second half oil storage chamber 113 is provided on the side of the first cylinder body, and the first cylinder body 101 and the second cylinder body 102 are oppositely connected so that the first half oil storage chamber 112 and the second half oil storage chamber 113 form an oil storage chamber; Both the first throwing ruler 205 and the second throwing ruler 206 are located above the oil storage cham...

Embodiment 3

[0046] Such as Figure 6 As shown, the components included in this embodiment and their connections are basically the same as those in Embodiment 1 and Embodiment 2, except that the crankshaft 2 is provided with an oil return hole 212 in the axial direction, and the oil return hole 212 is connected to the first cylinder The inner cavity of the body 101 is connected; a rotational connection between the cylinder body 1 and the crankshaft 2 is provided with an annular groove 213 coaxial with the crankshaft 2, and the crankshaft 2 is provided with a through hole 214 for communicating with the oil return hole 212 and the annular groove 213 ; The first cylinder 101 is provided with an oil return passage 126 corresponding to the annular groove, and the oil outlet of the oil return passage 126 communicates with the annular groove 213 .

[0047] In this technical solution, the recovered engine oil is sent into the annular groove 213 through the oil return passage 126 for storage. In t...

Abstract

The invention discloses a double-cylinder horizontally opposed engine. The double-cylinder horizontally opposed engine comprises a cylinder block body and a crankshaft, wherein the cylinder block body comprises a first cylinder block and a second cylinder block, and the first cylinder block and the second cylinder block are horizontally and oppositely connected; a first shell is arranged on the first cylinder block, and a second shell is arranged on the second cylinder block; and the two ends of the crankshaft are both rotationally connected to a joint of the first cylinder block and the second cylinder block, the crankshaft is provided with a first transmission gear and a second transmission gear, the first transmission gear and the second transmission gear are located at the two sides of a rotational joint of one end of the crankshaft and the cylinder block body, the first transmission gear corresponds to a first channel, and the second transmission gear corresponds to a second channel. According to the technical scheme, the first transmission gear and the second transmission gear are reasonably arranged on the crankshaft, so that the design of the first cylinder block and the first shell and the design of the second cylinder block and the second shell are optimized in light weight, the weight of the cylinder block body is reduced, and the weight of the whole unmanned aerial vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a two-cylinder horizontally opposed engine. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. UAVs are divided into electric UAVs and oil-powered UAVs according to their driving methods. Among them, multi-rotor oil-powered UAVs have the advantages of flexible maneuverability, fast response, and low operation requirements, and are widely used in agricultural plant protection, forestry, etc. Fire monitoring, aerial photography, land surveying, post-disaster damage assessment and other tasks. [0003] At present, drone engines include single-cylinder, twin-cylinder, in-line, four-cylinder, electric start, EFI, ai...
