Mode start internal combustion engine, can also using be separately provided mechanical compress elastic mechanism provide start power by the way of start internal combustion
Machine, due to second of technical scheme structure is relatively easy, be not required to set extra pressure inflatable device or load THR REV and
Bent axle can realize the keying of control valve, therefore preferred the latter by valve control machanism, i.e. the preferred side as the present invention
Case, the high speed drive of this piston swinging-arm internal combustion engine also include bent axle, and the diameter of axle portion of bent axle passes through linkage and rocking arm 2
Connection, it can realize that rocking arm 2 swings up and down, realizes the startup of internal combustion engine by electronic or driven by shaking bent axle rotation.
In order to ensure the firm axial movement of piston rod 1, ensure mistake of the rocking arm 2 in the firm axial movement of piston rod 1
Oscillating motion is avoided to interfere in journey, as a further improvement on the present invention scheme, as shown in Figure 1, Figure 2, shown in Fig. 8, described piston
Connection, described rocking arm 2 is fixedly mounted in the piston end surface for the internal combustion engine 3 that the both ends of connecting rod 1 are coaxially disposed with a pair respectively
It is connected, the chute that guide slide mechanism can be provided on rocking arm 2 and is arranged on by guide slide mechanism with piston rod 1
The connecting axle structure coordinated with chute on piston rod 1 or it is arranged on piston rod 1 and coordinates and be socketed in rocking arm
It is living during the firm axial movement of guide sleeve structure on 2, or the guiding Sliding Structures of other structures, i.e. piston rod 1
The link position of plug connecting rod 1 and rocking arm 2 can be oriented to pivot of the glide band motion rocker arm 2 around rocker arm shaft 21.
In order to prevent that oscillating motion interference occurs for rocking arm 2 during piston rod 1 from moving up and down, as entering for the present invention
One step improvement project, as shown in Figure 3, Figure 4, the internal combustion engine that the both ends of described piston rod 1 are coaxially disposed with a pair respectively are lived
The be hinged installation connection of the piston end surface of plug 3, and piston rod 1 includes the mutually hinged two sections connected as one in end, on
Lower two sections collectively constitute whole piston rod 1, and the articulated position of described rocking arm 2 and the two sections of piston rod 1 is coaxially cut with scissors
Connect in succession, i.e., piston rod 1 moves up and down swung up and down with motion rocker arm 2 during the two sections of piston rod 1 can be along same
The swing that left and right directions occurs for axle pin joint is stepped down, and then realizing prevents the oscillating motion of rocking arm 2 from interfering.
Oscillating motion band dynamic load is directly exported for the ease of rocking arm 2, scheme, described as a further improvement on the present invention
The swaying direction of rocking arm 2 be provided with connected transmission driving part, transmission driving part can be cam connecting shaft or
Person's lever connecting shaft or other attachment structures, rocking arm 2 can directly drive cam or lever by being driven driving part, enter
And realize and directly export oscillating motion band dynamic load.
Connecting rod 23 is connected for the ease of installation, scheme, described rocker arm shaft 21 stretch out as a further improvement on the present invention
To IC engine airframe, described connection swing arm 22 and connection connecting rod 23 are arranged at outside IC engine airframe.
The cylinder 4 that the high speed drive of this piston swinging-arm internal combustion engine is oppositely arranged using coaxial and cylinder mouth, passes through company
The up and down motion band motion rocker arm 2 for the piston rod 1 being connected between the internal combustion engine 3 of opposed cylinder 4 is on the center of rocker arm shaft 21
Lower swing, i.e., by internal combustion engine 3 up and down linear motion be changed into rocking arm 2 swing up and down motion or rocker arm shaft 21 it is non-whole
Circle circular motion, whole mechanism structure is relatively easy, it is possible to achieve the physical dimension of the shorter reciprocating member of size and tight
The arrangement to gather, and then can realize and reduce internal motivation consumption, while the opposed gas on the premise of rocking arm quantity is not increased
The structure of cylinder 4 not but not causes the load of rocking arm to increase, and is more beneficial for the direct conversion of internal motivation consumption, opposed gas on the contrary
Directly transmitted by piston rod 1 while a cylinder acting in cylinder 4 and consumed for the compression of opposite cylinder, so as to further real
Now reduce internal motivation consumption；Because axial direction of the piston rod 1 along internal combustion engine 3 is set, therefore piston rod 1 drives
Rocking arm 2 is smaller relative to the position off center of traditional crankshaft connecting rod system during swinging up and down, and then causes internal combustion engine
The lateral pressure of piston 3 is smaller, abrasion is smaller, and the shorter He of rocking arm 2 can be realized by the length and structure that rationally set rocking arm 2
The weight of lighter reciprocating motion parts, and then power performance when reduction internal consumption, raising fast state, so as to realize
Rocking arm 2 or the rocker arm shaft 21 being fixedly connected with rocking arm 2 drive such as plunger pump, reciprocating pneumatic equipment equipment；Bent axle is being set simultaneously
In the case of Crankshaft motion Starting mode, the required part of the high speed drive of non-piston swinging-arm internal combustion engine of bent axle
And transmission parts, bent axle can be set at an arbitrary position relative to rocking arm 2, set-up mode is more flexible, same additionally by bent axle
Power can be exported as ordinary internal combustion engine；Due to wobble gear rotating mechanism can be increased, therefore can be shaken by two pieces
The intermeshing travelling gear 24 additionally continuous rotation fortune of output is realized in the alternate intermittent of travelling gear 24 rotation on arm axle 21
It is dynamic, especially suitable for the internal combustion engine of the equipment such as plunger pump, reciprocating pneumatic equipment can be promoted.
