The upper hanging component 3 can enable the generator assembly 2 to have an X-direction buffer function, a Y-direction buffer function and a Z-direction buffer function relative to the internal combustion engine assembly 1.
The elastic legs 6 are used for elastically supporting the generator assembly 2 from the ground, and are usually four in number and also distributed in a rectangular shape. The elastic leg 6 includes a leg support 61, a lower leg 64 capable of extending and retracting in the Z direction relative to the leg support 61, and the bottom of the lower leg 64 is usually provided with a pressure plate or an elastic pressure foot for increasing the contact area. A leg spring 63 for driving the lower leg 64 to extend and retract downward is provided between the lower leg 64 and the leg bracket 61.
The Z-position of the leg support 61 relative to the moving frame 21 is adjustable and lockable in a fixed position. The concrete structure is as follows: the side of the leg support 61 is provided with a leg slot 611, and the movable frame 21 is connected to the leg slot 611 through a leg clip 62.

The position of the sliding sleeve 5 in the X direction relative to the moving frame 21 is adjusted between the sliding sleeve 5 and the moving frame 21 by the sliding sleeve adjusting screw 51. It should be noted that: the two sloping plates 52 are of the same size and are also positioned to correspond to the extent of extension of the two lower legs 64 of that side.
As can be seen from the above description, the lower end of the moving frame 21 is cushioned by the elastic legs 6 in the vertical (Z direction), and the extension degree of the elastic legs 6 can be adjusted.

The power input end of generator body 23 is equipped with connector two 8, the lateral part of connector two 8 be equipped with telescopic tooth plate 71 assorted fixed tooth plate 81, because telescopic tooth plate 71 adopts the retractable design, consequently the profile of conventional gear can't be designed to its profile, this has just led to telescopic tooth plate 71 and has some impact with fixed tooth plate 81 complex in-process, in order to improve this condition, the surface of this embodiment connector two 8 still is equipped with and links up with connector two 8 profile assorted cushion collar 82. It should be noted that: the outer contours of the fixed toothed plate 81 and the telescopic toothed plate 71 can be optimized properly, the profiles of the fixed toothed plate and the telescopic toothed plate are designed to be similar to the profiles of conventional gear teeth in the prior art, the impact transmitted between the fixed toothed plate and the telescopic toothed plate is reduced, the strength of the first connector 7 and the strength of the second connector 8 are improved as much as possible, and the damage caused by overlarge torque is avoided. When the generator assembly 2 and the internal combustion engine assembly 1 are in a combined state, the telescopic toothed plate 71 and the fixed toothed plate 81 are meshed.
The rubber sleeve and the elastic pad 15 at each position can be replaced by other buffer structures in the prior art, such as a spring, a torsion spring, and the like.
When not in use, as shown in fig. 1, the generator assembly 2 is separated from the engine assembly 1, the generator assembly 2 is located on the top of the engine assembly 1, and the generator assembly 2 cannot be separated from the top of the engine assembly 1 due to the elastic legs 6 and the locking device. The hook holder 35 is separated from the hook 36. The upper sliding bush 31 is located at the upper end of the middle cross beam 12 under the action of gravity. Furthermore, the lower sliding sleeve 41 is located at the uppermost end of the sliding slot 13, and the upper sliding sleeve 31 performs a unidirectional upward limiting effect on the generator assembly 2 through the action of the upper extending portion 42.
When power generation is needed, the generator assembly 2 is moved along the X direction, the lower connecting rod 44 is pulled out relative to the X-direction loop bar 24, the lower sliding sleeve 41 is positioned at the uppermost end of the sliding groove 13, so that the sliding of the generator assembly 2 above the fixed support can be guided, and when the X-direction loop bar 24 is pulled out to the maximum state, namely the stop 443 contacts with the end of the limiting groove 241, the generator assembly 2 moves downwards along the upright column until the clamping hook 36 is combined with the hanging buckle 32. The adjusting screw 51 is rotated to make the elasticity of the elastic supporting leg 6 and the upper sliding sleeve spring 34 approximately balanced, so as to ensure the balance of stress of each connecting and supporting part of the generator assembly 2.
When the generator assembly 2 moves to the lowest end, the bottom of the movable frame 21 and the bottom of the fixed bracket are supported by the X-direction elastic cushion 15. Furthermore, the lower sliding sleeve 41 is not yet moved to the lowest end of the sliding chute 13, so as to avoid the bottom of the sliding chute 13 from causing a rigid connection to the moving frame 21.
The telescopic toothed plate 71 adopts a telescopic design, so that the phenomenon that the telescopic toothed plate 71 abuts against the fixed toothed plate 81 cannot occur, and large radial compensation can be realized between the telescopic toothed plate 71 and the fixed toothed plate. During normal power generation, under the effect of centrifugal force, telescopic toothed plate 71 is in the state of stretching out completely, does not influence normal torque transmission.
Compared with the prior art, the generator assembly 2 and the internal combustion engine assembly 1 of the present embodiment are movably separated. The upper end of the movable frame 21 can realize three-way buffering and vibration absorption between the upper hanging assembly 3 and the fixed frame, and the lower end of the movable frame 21 can also realize three-way buffering and vibration absorption through the lower pull rod assembly 4, the elastic supporting leg 6 and the X-direction elastic cushion 15. The generator body 23 is connected with the power output shaft of the internal combustion engine 111 through the first connector 7 and the second connector 8, torque transmission is achieved through the first connector 7 and the telescopic toothed plates 71 capable of radially stretching, and when torque transmission is guaranteed, the phenomenon of tooth jacking when the two are combined radially is avoided.
On the other hand, because the vibration of the internal combustion engine 111 is difficult to transmit to the generator assembly 2, the vibration of the generator assembly is greatly reduced, and the service life of the electrical part of the generator is remarkably prolonged. The double-layer fixed support of the internal combustion engine assembly 1 also improves the volumes of the oil tank 121 and the water tank 112, which is beneficial to improving the endurance of the whole engine, and meanwhile, the internal combustion engine 111 is arranged at the bottom, so that the suction noise reduction material is convenient to arrange around the internal combustion engine 111. When in the non-operating state, the occupied space is smaller because of the stacked design.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
