DETAILED DESCRIPTION

[0054] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0055] Please refer to Figures 1 to 14 The utility model provides a lawn mower, comprising a battery compartment 10, a machine cover 20, a mowing component 30, a wheel assembly 40, and a hand lever 50;

[0056] The battery compartment 10 is disposed inside the cover 20;

[0057] The cover 20 is arranged on the top of the mowing component 30;

[0058] The front and rear sides of the bottom of the mowing component 30 are arranged on the wheel assembly 40;

[0059] The handrail 50 is provided at the rear of the mowing component 30;

[0060] When the expansion battery is placed in the battery compartment 10, the expansion battery is electrically connected to the mowing component 30, and the expansion battery provides a working power source for the mowing component 30. The mowing component 30 performs a mowing action under the action of the working power source.

[0061] When the lawn mower needs to move, the operator applies a moving force through the hand lever 50 , and the mowing component 30 transmits the moving force to the wheel assembly 40 to perform the moving action.

[0062] In this embodiment, the battery compartment 10 is a cavity of conventional design, and the specific shape can be determined according to the shape of the expanded battery. For example, when the expanded battery is a rectangular structure, the interior of the battery compartment 10 is also correspondingly configured as a rectangular structure, and when the expanded battery is placed in the battery compartment 10, the interface of the expanded battery for providing electrical energy needs to be connected to the interface in the battery compartment 10 for receiving electrical energy. The cover 20 is a conventionally designed outer shell, and the specific shape and material can be selected according to actual needs. It is mainly used to protect the battery compartment 10 and other components inside the lawn mower as much as possible. The mowing component 30 adopts a conventional design and can perform mowing actions based on the electrical energy provided by the expanded battery. The bottom of the mowing component 30 spans the wheel assembly component 40, and its front and rear sides can be understood as the front and rear sides of the mowing component 30. The wheel assembly 40 adopts a conventional design and can be divided into two parts, front and rear. The front part is connected to the bottom front side of the mowing component 30, and the rear part is connected to the bottom rear side of the mowing component 30, thereby supporting the entire mowing component 30 and ensuring that the mowing actuator of the mowing component 30 can maintain a certain clearance from the ground. The handrail 50 adopts a conventional design. The tail of the mowing component 30 can be understood as the rear part. The handrail 50 is set at the tail of the mowing component 30 for easy operation. The handrail 50 is mainly used to manually provide driving power for the mower. It should be noted that due to the limited amount of electrical energy stored in the expanded battery, manually providing driving power through the handrail 50 will effectively increase the continuous operation time of the mower. In specific implementation, the expanded battery can be a 48V battery, that is, a battery that can provide 48V DC power to the outside. The mowing component 30 performs the mowing action under the action of the 48V operating voltage.

[0063] In one possible implementation, Figures 5 to 10 The mowing component 30 includes a grass discharge structure 31, a driving structure 32, and a mowing blade 33;

[0064] The handrail 50 is arranged above the tail of the grass-clearing structure 31;

[0065] The front and rear sides of the grass removal structure 31 are arranged on the wheel assembly 40;

[0066] The driving structure 32 is arranged on the upper side of the grass discharge structure 31 and passes through the grass discharge structure 31 to rotate the mowing blade 33 to be arranged on the lower side of the grass discharge structure 31;

[0067] When the capacity expansion battery is installed in the battery compartment 10 , the capacity expansion battery is electrically connected to the driving structure 32 .

[0068] In this embodiment, the grass removal structure 31, drive structure 32, and mowing blades 33 can all be conventionally designed. The drive structure 32 and mowing blades 33 are located on the upper and lower sides of the grass removal structure 31, respectively. The drive portion of the drive structure 32 must pass through the grass removal structure 31 to drive the mowing blades 33. The mowing blades 33 must maintain a certain clearance from the ground to prevent damage from bumps.

[0069] In one possible implementation, Figure 2 , the battery compartment 10 is provided with a battery interface 11;

[0070] The battery interface 11 is electrically connected to the driving structure 32 .

[0071] In this embodiment, the battery interface 11 needs to match the power supply interface of the expansion battery to facilitate the extraction of power from the expansion battery, thereby providing the operating voltage for the drive structure 32 through the expansion battery. In specific implementations, the expansion battery can be a 48V battery, that is, a battery that can provide 48V DC power to the outside. The battery interface 11 can be configured as a 48V positive and negative connector that matches the interface of the expansion battery.

[0072] In one possible implementation, Figures 9 to 11 , the driving structure 32 includes a driving motor 321, a radiator 322, and a motor support base 323;

[0073] The driving motor 321 is electrically connected to the battery interface 11;

[0074] The driving motor 321 and the radiator 322 are fixedly mounted on the motor support base 323;

[0075] The motor support seat 323 is arranged on the upper side of the grass removal structure 31;

[0076] The driving shaft of the driving motor 321 passes through the grass removal structure 31 to rotate the mowing blade 33 to be disposed on the lower side of the grass removal structure 31 .

[0077] In this embodiment, the drive motor 321 can adopt a conventional DC drive motor. The radiator 322 adopts a conventional model. The motor support seat 323 can be determined according to the specific implementation needs. In a specific embodiment, the drive motor 321 and the radiator 322 are fixed on the motor support seat 323. An opening is provided in the middle of the grass-removing structure 31, and a plurality of bolt holes are provided around the opening. A plurality of bolt holes can also be provided on the edge of the motor support seat 323, so that the motor support seat 323 can be fixed to the grass-removing structure 31 by a plurality of bolts. The drive shaft of the drive motor 321 extends to the lower side of the grass-removing structure 31 through the opening on the grass-removing structure 31. The mowing blade 33 is fixedly provided at the distal end of the drive shaft of the drive motor 321. When the drive motor 321 is working, the drive shaft and the mowing blade 33 rotate synchronously, thereby realizing the mowing action.

[0078] In one possible implementation, Figure 12 The bottom of the grass discharge structure 31 is provided with a concave grass discharge channel 311;

[0079] The grass discharge port 3111 of the grass discharge channel 311 is located at the rear of the grass discharge structure 31 .

[0080] In this embodiment, the grass discharge channel 311 is concave upward and surrounds the drive shaft of the drive motor 321, corresponding to the circular shape formed by the rotation of the mowing blade 33. When the mowing blade 33 is mowing, the cut grass will fly out of the grass discharge port 3111 in the direction of the mowing blade 33's rotation.

[0081] In one possible implementation, Figures 10 to 12 , the mowing component 30 further includes a fan impeller 34;

[0082] The fan impeller 34 is disposed on the driving shaft at a lower side of the grass removal structure 31 and is located above the mowing blade 33 .

[0083] In this embodiment, the fan impeller 34 can be a conventional model. By providing the fan impeller 34, it is easier to discharge the broken grass through the grass discharge channel 311 to the outside of the lawn mower.

[0084] In one possible implementation, Figures 1 to 6 、 Figures 12 to 14 A rear baffle 60 is provided on the upper side of the tail of the grass removal structure 31.

[0085] In this embodiment, the rear baffle 60 can be of conventional design. By disposing the rear baffle 60 on the upper side of the tail of the grass discharge structure 31, i.e., above the grass discharge port 3111, it can effectively prevent the broken grass discharged from the grass discharge port 3111 from flying upward, thereby reducing the adverse effects of the discharged broken grass on the operator.

[0086] In one possible implementation, Figure 4 、 Figure 6 、 Figure 11 The wheel assembly 40 includes a first wheel 401, a second wheel 402, a third wheel 403, a fourth wheel 404, a first wheel connecting shaft 405, and a second wheel connecting shaft 406;

[0087] The first wheel 401 and the second wheel 402 are arranged on both sides of the first wheel connecting shaft 405;

[0088] The third wheel 403 and the fourth wheel 404 are arranged on both sides of the second wheel connecting shaft 406;

[0089] The front and rear sides of the grass-removing structure 31 are sequentially arranged on the first wheel connecting shaft 405 and the second wheel connecting shaft 406 .

[0090] In this embodiment, the first wheel 401, the second wheel 402, the third wheel 403, and the fourth wheel 404 are all conventional wheels. The first wheel connecting shaft 405 and the second wheel connecting shaft 406 are both conventional wheel connecting shafts. In a specific embodiment, the operator applies a forward-moving force to the handrail 50, and the handrail 50 transmits the force to the first wheel connecting shaft 405 and the second wheel connecting shaft 406 respectively through the grass-removing structure 31. After receiving the forward force, the first wheel connecting shaft 405 and the second wheel connecting shaft 406 cause the first wheel 401, the second wheel 402, the third wheel 403, and the fourth wheel 404 to rotate forward, thereby achieving forward movement of the lawn mower. The principles of the lawn mower's backward movement, left turn, right turn, etc. are similar to those of forward movement and will not be repeated here.

[0091] In one possible implementation, Figure 6 and Figure 11 A front fender 70 is provided on the outer side of the first wheel connecting shaft 405.

[0092] In this embodiment, the front baffle 70 can be of conventional design. By providing the front baffle 70 on the outside of the first wheel connecting shaft 405, i.e., at the head of the lawn mower, foreign matter can be effectively prevented from entering the interior of the lawn mower from the front, thereby providing a certain degree of protection for the internal structure of the lawn mower.

[0093] In one possible implementation, Figure 8 The grass removal structure 31 has a first bayonet 312 at the bottom of the front side and a second bayonet 313 at the bottom of the rear side.

[0094] The first wheel connecting shaft 405 is engaged with the grass removal structure 31 through the first bayonet 312;

[0095] The second wheel connecting shaft 406 is engaged with the grass-removing structure 31 through the second bayonet 313 .

[0096] In this embodiment, the first bayonet 312 and the second bayonet 313 adopt a conventional bayonet design and are both arranged in pairs on the left and right sides of the grass-removing structure 31. The first bayonet 312 is arranged near the head of the grass-removing structure 31, i.e., the front side, and the second bayonet 313 is arranged near the tail of the grass-removing structure 31, i.e., the rear side. For example, the first bayonet 312 and the second bayonet 313 can be designed as semicircular notches, and the cross-section of the first wheel connecting shaft 405 and the second wheel connecting shaft 406 is a circle that matches the above-mentioned semicircular notches. The grass-removing structure 31 is connected to the first wheel connecting shaft 405 and the second wheel connecting shaft 406 through the first bayonet 312 and the second bayonet 313, thereby serving as the support structure of the entire lawn mower. The overall structure is simple and the implementation cost is low.

[0097] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
