[0037] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0038] like Figures 1 to 6As shown, the utility model provides an extended-range lawn mower, including a frame 10, a cutting device, a battery 11, a generator 12 and a fuel tank 13. The battery 11 supplies energy to the cutting device, the generator 12 is electrically connected to the battery 11, and the fuel tank 13 is connected to the oil inlet pipeline of the generator 12. The generator 12 is arranged on the frame 10, and a mounting bracket 14 is provided on the frame 10 to avoid the generator 12. The fuel tank 13 is arranged on the mounting bracket 14 to avoid the generator 12.

[0039] The vehicle frame 10 is provided with a mounting bracket 14 that avoids the generator 12, and the fuel tank 13 is arranged on the mounting bracket 14 to avoid the generator 12, effectively preventing the vibration of the generator 12 from being directly transmitted to the fuel tank 13. The vibration of the generator 12 needs to be transmitted to the mounting bracket 14 through the vehicle frame 10, and then transmitted to the fuel tank 13. The vibration of the generator 12 is greatly weakened during the transmission process, which greatly reduces the vibration received by the fuel tank 13, is beneficial to improving the stability of the fuel tank 13, and greatly reduces the fatigue strength of the fuel tank 13 and the mounting bracket 14, which is beneficial to ensuring the service life of the fuel tank 13, and can also reduce the occurrence of excessive fluctuations in the fuel in the fuel tank 13 due to vibration and overflow from the fuel tank 13. The fuel tank 13 is far away from the generator 12, and can also reduce the risk of the temperature of the fuel tank 13 rising due to the high temperature of the generator 12, thereby improving safety.

[0040] It should be noted that the extended-range lawn mower also includes a traveling mechanism, and the battery 11 also serves as the traveling mechanism.

[0041] In order to improve the stability of the fuel tank, the mounting bracket 14 is in the shape of a Chinese character "J". The generator 12 is located inside the mounting bracket 14 and is set at a certain distance from the mounting bracket 14. The generator 12 is located inside the Chinese character "J"-shaped mounting bracket 14, which can also make full use of the space on the frame 10, making the extended-range lawn mower structure more compact. The Chinese character "J"-shaped mounting bracket 14 can also form a multi-point support effect, thereby increasing the stability of the overall structure.

[0042] Specifically, the mounting bracket 14 includes a top plate 141, supporting side plates 142 located on either side of the top plate 141, and a supporting bottom plate 143 located at the bottom of the supporting side plates 142. The fuel tank 13 is mounted on the top plate 141, and the supporting bottom plate 143 is connected to the vehicle frame 10. The supporting side plates 142 are inclined upward from bottom to top toward the interior of the mounting bracket 14. The inclined supporting side plates 142 increase the supporting area and provide better stability for the fuel tank 13. This also allows the fuel tank 13 to utilize gravity to supply oil naturally when located above the generator 12, simplifying the oil circuit design and reducing the mechanical devices required for pumping.

[0043] In order to further reduce the vibration of the fuel tank 13, a shock-absorbing pad 15 is provided between the support base 143 and the frame 10. The shock-absorbing pad 15 can absorb and attenuate the vibration transmitted to the mounting bracket 14 by the generator 12 or other mechanical equipment, thereby further reducing the vibration of the fuel tank 13.

[0044] In order to further improve the installation stability of the fuel tank 13, a supporting cross plate 145 is also provided on the top plate 141 and is cross-set therewith. The supporting cross plate 145 and the top plate 141 form a supporting plane 146 for installing the fuel tank 13, which can provide more fixing points, making the fuel tank 13 more stable during installation and improving the stability of the fuel tank 13.

[0045] Among them, the supporting cross plate 145 includes a first part 1451 integrally formed with the top plate 141 and a second part 1452 detachably connected to the top plate 141. The second part 1452 is provided with an upwardly set limiting rib 144. The fuel tank 13 is installed within the range limited by the limiting rib 144 to ensure that the fuel tank 13 is installed within the predetermined range. The upwardly set limiting rib 144 can provide additional support to make the fuel tank 13 more stable after installation.

[0046] In order to improve the overall stability of the lawn mower, the fuel tank 13 and the generator 12 are arranged side by side behind the battery 11. The parallel arrangement can make the weight distribution of the fuel tank 13 and the generator 12 more even, which helps to improve the overall stability of the equipment and make full use of the limited space to make the equipment more compact as a whole.

[0047] To further protect the fuel tank 13, the range-extended lawn mower includes a protective cover 17 mounted on the mounting bracket 14. This cover prevents external objects from striking the fuel tank 13, reducing the risk of damage or fuel leaks. The protective cover 17 is detachably connected to the retaining ribs 144 for easy assembly and disassembly.

[0048] To facilitate future maintenance, support base plate 143 is removably mounted to frame 10 via bolts 16. Bolts 16 allow for quick and easy installation and removal of mounting bracket 14, facilitating separate maintenance of fuel tank 13 and generator 12. Specifically, support base plate 143 and shock-absorbing pad 15 are each provided with through-holes, while frame 10 is provided with threaded holes. Bolts 16 are sequentially connected through the two through-holes to the threaded holes in frame 10.

[0049] It is understood that in other embodiments, to further enhance the fuel tank's mounting stability, at least two mounting brackets are provided, all arranged along the front and rear sides of the vehicle frame. Multiple mounting brackets can more evenly distribute the load, effectively reducing vibration and shaking of the fuel tank, improving the tank's stability, and increasing the load capacity to accommodate heavier fuel tanks. The number of mounting brackets can be two, three, four, or any other suitable number.

[0050] It is understandable that in other embodiments, the mounting bracket may also be in a suitable shape such as a "T" shape, a "Z" shape, a ring shape, a grid shape, a multi-arm shape, etc., to provide stable support for the fuel tank.

[0051] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
