TECHNICAL FIELD

[0001] The application relates to the technical field of power generation equipment, in particular to a high-stability gasoline generator. BACKGROUND

[0002] The gasoline generator is widely used in various temporary or mobile power supply scenes due to its compact structure, rapid start and portability. However, in the actual use process, high-frequency vibration caused by engine combustion and mechanical operation easily leads to whole machine shaking, component loosening and even damage, affecting the service life and operation safety of the equipment.

[0003] In addition, when being transported or placed on a non-horizontal ground, if there is a lack of effective limiting and buffering structure, the generator is also prone to overturning or internal element displacement.

[0004] In the prior art, rubber pads or spring shock absorbers are usually arranged below the base to absorb vibration, but such a scheme is passive support and is difficult to balance the buffering in the vertical direction and the limiting in the horizontal direction; at the same time, the top lacks effective pressing structure and cannot prevent the generator body from jumping or deviating under severe working conditions.

[0005] Therefore, there is an urgent need for a gasoline generator support structure with reasonable structure, high stability, multi-directional buffering and reliable limiting function. SUMMARY

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Combined with appendix Figs. 1-3 As shown, a high-stability gasoline generator includes a generator body 1 and a base 2 located on the outside of the generator body 1. Two sets of inverted L-shaped side plates 3 are connected to the top of the base 2 on both sides. The long arm end of the L-shaped side plate 3 is connected to the base 2, and the short arm end is connected to an upper stabilizing plate 4 for pressing down the top of the generator body 1. A floating plate 5 is also connected to the top of the base 2. Multiple sets of floating support feet 6 are connected between the floating plate 5 and the top wall of the base 2. Multiple sets of upper support ridges 7 are formed on the top of the floating plate 5 along its length or width direction. The upper support ridges 7 are made of flexible material. A hollowed-out counterweight groove 8 is also provided in the middle of the base 2.

[0030] In one embodiment:

[0031] The upper stabilizing plate 4 is an arc-shaped plate or a flat plate, and its lower surface is provided with a flexible pressure pad 9. The hardness of the flexible pressure pad 9 is lower than the surface hardness of the generator body 1 shell. The floating support feet 6 are evenly arranged and there are no less than four sets.

[0032] In a specific implementation of the present invention, the floating support feet 6 are evenly arranged and there are no fewer than four sets. The floating support feet 6 include an outer rubber sleeve 10 and a partition 11 disposed in the middle of the outer rubber sleeve 10.

[0033] The upper and lower parts of the partition 11 are both connected to conical shock absorbers 12 disposed inside the outer rubber sleeve 10. The small diameter ends of the two conical shock absorbers 12 are connected to the partition 11, and the large diameter ends are connected to the top and bottom of the outer rubber sleeve 10, respectively.

[0034] The upper support protrusion 7 is made of any material among silicone, polyurethane or thermoplastic elastomer, with a Shore hardness of 30A to 70A.

[0035] In one embodiment:

[0036] The conical damping element 12 consists of several prismatic cells connected along the axial and circumferential directions to form a conical shape. The short arm end of the L-shaped side plate 3 is connected to the upper stabilizing plate 4 by an adjusting screw 13.

[0037] In one embodiment:

[0038] The upper support protrusions 7 are arranged parallel to each other and at equal intervals along the length of the floating plate 5. The distance between the center lines of two adjacent sets of upper support protrusions 7 is 20-50mm. The height of each set of upper support protrusions 7 is 3-8mm. The rhomboid cell is a hexagonal or quadrilateral honeycomb structure with a wall thickness of 0.8-2.0mm. The cell height gradually changes along the conical axis.

[0039] The two conical shock absorbers 12 are coaxially arranged, and their large-diameter ends are integrally formed with the top and bottom walls of the outer rubber sleeve 10, respectively, while their small-diameter ends are connected to the upper and lower surfaces of the partition plate 11 by vulcanization or in-mold injection molding.

[0040] In practical use, it includes a generator body 1 and a rectangular base 2 surrounding its outer side. A set of inverted L-shaped side plates 3 are fixedly connected to the top left and right sides of the base 2. The long arm end of the L-shaped side plate 3 is fixed to the base 2 by bolts, and the short arm end extends downward and is connected to a stabilizing plate 4, which is used to press the top of the generator body 1 from above to prevent it from jumping or lateral displacement during operation.

[0041] A floating plate 5 is provided at the top center of the base 2. The floating plate 5 is not rigidly connected to the base 2, but is elastically supported on the top wall of the base 2 by multiple sets of floating support feet 6.

[0042] In this embodiment, there are six sets of floating support feet 6, which are evenly distributed in the four corners and the middle area of ​​the floating plate 5, satisfying the requirement of "no less than four sets". Each set of floating support feet 6 includes an outer rubber sleeve 10, and a metal partition 11 is embedded in the middle of its interior.

[0043] A conical shock absorber 12 is connected to the upper and lower surfaces of the partition 11, respectively. The small diameter ends of the two conical shock absorbers 12 are connected to the partition 11, while the large diameter ends are connected to the top inner wall and bottom inner wall of the outer rubber sleeve 10, respectively, forming a symmetrical double-cone buffer structure.

[0044] In one embodiment, the conical damper 12 is composed of multiple prismatic cells continuously connected along the axial and circumferential directions, forming an overall conical honeycomb structure. These prismatic cells can be hexagonal honeycomb structures or quadrilaterals, with a wall thickness of 1.2 mm. The cell height gradually increases from the smaller end to the larger end along the conical axial direction, giving the damper a gradually varying stiffness characteristic during compression and effectively absorbing vibration energy of different frequencies.

[0045] The top surface of the floating plate 5 is integrally formed with multiple sets of upper support protrusions 7, which are arranged parallel and equidistantly along its length. The center-line distance between two adjacent sets of upper support protrusions 7 is 35mm, and the height of a single protrusion is 5mm. The upper support protrusions 7 are made of thermoplastic polyurethane material with a Shore hardness of 60A, which is a flexible material that can provide sufficient support while avoiding damage to the bottom of the generator body 1.

[0046] The upper stabilizing plate 4 is a flat plate, and a flexible pressure pad 9 is bonded to its lower surface. The pressure pad 9 is made of silicone material with a Shore hardness of 50A, which is lower than the hardness of the generator body 1 shell, to ensure that no scratches or stress concentration are generated when it is pressed.

[0047] The short arm end of the L-shaped side plate 3 is connected to the upper stabilizing plate 4 by an adjusting screw 13. The adjusting screw 13 passes through the short arm end and is threaded to the upper surface of the upper stabilizing plate 4. The user can adjust the vertical position of the upper stabilizing plate 4 by rotating the screw, thereby controlling the clamping force on the generator body 1. The base 2 has a hollow counterweight groove 8 in the middle, which can be used to embed cast iron blocks or other counterweights to lower the center of gravity of the whole machine and improve the anti-overturning ability on slopes or during transportation.

[0048] In use, place the generator body 1 on the floating plate 5, ensuring its bottom is flush with the upper support ridge 7; tighten the adjusting screw 13 to moderately press the flexible pressure pad 9 against the top of the generator; if necessary, add a counterweight in the counterweight slot 8. During operation, vibrations are transmitted to the floating plate 5 via the upper support ridge 7, and then efficiently attenuated by the double-cone damping element 12 within the floating support foot 6. Simultaneously, the L-shaped side plate 3 and the upper stabilizing plate 4 restrict horizontal and vertical displacement, achieving highly stable operation.

[0049] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0050] The working principle of this invention is as follows: When in use, the generator body 1 is placed on the floating plate 5, and its bottom contacts the flexible upper support protrusion 7 to form a buffer support surface.

[0051] The vibration generated during operation is transmitted to the floating plate 5 through the upper support protrusion 7, and then absorbed and attenuated by multiple sets of floating support feet 6: the upper and lower conical shock absorbers 12 inside the floating support feet 6 deform symmetrically on both sides of the partition plate 11, and dissipate vibration energy by using the elastic compression of the honeycomb prismatic cells to achieve efficient vibration reduction in the vertical direction; at the same time, the floating plate 5 can float slightly within the base 2 to isolate external impacts.

[0052] The top stabilizing plate 4 applies controllable pressure via adjusting screw 13, which, together with the flexible pressure pad 9, limits the vertical jump and lateral displacement of the generator body 1. The counterweight groove 8 in the middle of the base 2 can be used to add counterweights, lower the center of gravity, and enhance anti-overturning ability. The overall structure works synergistically to significantly improve the stability and safety of the gasoline generator during operation and movement.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
