Description

Technical Field

[0001] This invention relates to the field of garden equipment technology, and in particular to a lithium-ion battery-powered lawn mower for garden lawns. Background Technology

[0002] As an important part of urban greening, lawns not only beautify the urban environment but also provide a place for citizens to relax. However, as lawns are used for a long time, the grass grows too long and affects their appearance, so regular mowing is necessary to maintain their beauty.

[0003] Chinese patent CN102907211B discloses a lawn mower including a frame, wheels, a fixed blade, a rotary blade, and a push handle connected to the frame. Two wheels are located on both sides of the frame. The two ends of a rotary blade shaft pass through the side plates of the frame on both sides and are connected to the two wheels. A transmission mechanism is provided between each wheel and the rotary blade shaft. The fixed blade is fixedly connected to the side plate of the frame. The rotary blade is mounted on the rotary blade shaft and forms a shearing gap with the fixed blade. An adjustment mechanism is provided between the side plate of the frame and the rotary blade shaft. This adjustment mechanism can adjust the shearing gap by adjusting the position of the rotary blade shaft. Although the above patent can cut grass on lawns, the cutting width of the rotary blade and the fixed blade is a fixed value. However, when dealing with lawn areas of different sizes and complex shapes, the fixed cutting width becomes a major limitation. In narrow passages or along edges, excessively wide cutting widths make operation extremely inconvenient and may even prevent the job from being completed; while in large, flat areas, excessively narrow cutting widths result in low efficiency and fail to fully utilize the lawnmower's performance. This fixed cutting width makes the lawnmower lack flexibility in adapting to different lawn conditions, resulting in low adaptability and severely impacting overall mowing efficiency.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a lithium-ion battery lawnmower for garden lawns is proposed, which can flexibly adjust the width of the mowing, improve adaptability and overall mowing efficiency. Summary of the Invention

[0005] To overcome the limitation that the fixed mowing width becomes a major constraint when dealing with lawn areas of varying sizes and complex shapes, which makes the mower lack flexibility in adjusting to different lawn conditions and has low adaptability, seriously affecting the overall mowing efficiency, this invention provides a lithium-ion battery-powered lawn mower for garden lawns that can flexibly adjust the mowing width, thereby improving adaptability and overall mowing efficiency.

[0006] This invention is achieved through the following technical solution:

[0007] A lithium-ion battery-powered lawn mower for gardens includes a movable frame and a collection box fixed to the movable frame for collecting cut grass. An elastic cover is connected to the feed end of the collection box. A mounting plate penetrating the elastic cover is fixed to the collection box. Two telescopic plates are slidably connected to the mounting plate, with the front and rear telescopic plates slidably connected. The telescopic plates are fixedly connected to the elastic cover. Wheels are symmetrically rotatably connected to the telescopic plates. The mower also includes a cylinder fixed to the bottom of the mounting plate, with the end of the cylinder's telescopic rod fixedly connected to the telescopic plate. A housing is fixed to the bottom of the mounting plate. An electric rotating shaft is installed between the components, and a rotating frame is fixedly mounted on the electric rotating shaft. An electric cutter is slidably connected to the rotating frame for cutting the grass in the lawn. A triggering component is provided on the housing to drive the electric cutter to move. A slotted plate is symmetrically fixed to one of the telescopic plates and contacts the triggering component. The slotted plate is used to drive the triggering component to operate. The triggering component drives the electric cutter to move horizontally, so that the electric cutter can flexibly adjust the cutting width. A blowing component is provided between the telescopic plate and the electric rotating shaft to blow the cut grass into the collection box.

[0008] Further explanation: The triggering component includes a swing frame rotatably connected to the electric cutter, an n-shaped rod rotatably connected to the swing frame, the n-shaped rod being rotatably connected to the swing frame for driving the swing frame to move, an oblong hole symmetrically opened on the n-shaped rod, a movable tube slidably mounted on the housing, a trigger frame fixedly mounted on the movable tube, the end of the trigger frame being slidably connected to the oblong hole, and a contact rod symmetrically fixed to the movable tube and slidably connected to the slotted plate.

[0009] Further explanation: The blowing assembly includes a telescopic nozzle fixed between telescopic plates. The air outlet of the telescopic nozzle faces to the right and is used to blow air to move the cut grass. Both ends of the telescopic nozzle are connected to air outlet pipes. The tail end of the air outlet pipe passes through the mounting plate and communicates with the inside of the housing. A fan blade is fixedly mounted on the electric rotating shaft to blow air into the air outlet pipe. A suction pipe is symmetrically connected to the housing. The air outlet of the suction pipe is located below the fan blade. The tail ends of the suction pipes on the front and rear sides pass through the mounting plate. A fixed shell connected to the tail end of the suction pipe is fixedly connected to the collection box. A mesh plate is fixedly connected to the inside of the fixed shell to block the grass in the collection box. A pushing assembly is provided on the telescopic plate to push the grass to the right and into the elastic cover.

[0010] Further explanation: The feeding assembly includes a telescopic conveyor roller that rotates between the telescopic plates to drive the cut grass to move to the right, and a belt assembly is connected between the end of the telescopic conveyor roller and the axle of one of the wheels.

[0011] Further explanation: the feeding assembly also includes a telescopic guide plate fixed between the telescopic plates. The telescopic guide plate is located on the right side of the telescopic conveying roller and is inclined to guide the cut grass.

[0012] Further explanation: The lithium-ion lawn mower for garden lawns also includes a blocking component. The blocking component includes an intercepting frame rotatably connected to the inner side of the telescopic plate. The front intercepting frame and the rear intercepting frame are slidably connected to block stones in the lawn. An L-shaped block is fixed on the intercepting frame. A swing block is rotatably connected to the telescopic plate. A connecting spring connects the swing block and the L-shaped block. A drive component is provided between the swing block and the telescopic plate to drive the swing block to swing.

[0013] Further explanation: the drive assembly includes a button mounted on the swing block, the button corresponding to the L-shaped block, an electric push rod rotatably connected to the telescopic plate, the telescopic end of the electric push rod rotatably connected to the swing block, and the electric push rod and the button electrically connected through the control module.

[0014] To further explain, the lithium-ion lawn mower for garden lawns also includes a guide frame fixed to the inside of the collection box. The discharge end of the guide frame is fitted with a breathable collection bag for collecting the cut grass.

[0015] Further explanation includes a rubber sleeve that is fixedly mounted on the movable frame to increase friction with the hand.

[0016] Further explanation includes a protective cover fixed to the top of the mounting plate, with the upper part of the electric shaft located inside the protective cover, which can protect the upper part of the electric shaft.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By activating the cylinder, the front and rear telescopic plates move outward, and the electric cutter moves to the left in sync with the telescopic plates. The leftward movement of the electric cutter adjusts the mowing width. Once the mowing width is adjusted, the cylinder is closed, and the electric cutter begins to rotate clockwise and move in a circular motion to cut the grass on the lawn. In this way, by adjusting the positions of the telescopic plates and the electric cutter, the mowing width can be flexibly adjusted to adapt to different lawn conditions, thereby improving adaptability and overall mowing efficiency.

[0019] 2. Under the action of the telescopic nozzle and the telescopic conveying roller, the telescopic nozzle can spray air to blow the cut grass to the right, and the telescopic conveying roller reverses to push the cut grass into the elastic cover. The grass is then discharged into the collection box for collection. In this way, the cut grass can be collected and processed for subsequent processing.

[0020] 3. With the action of the interceptor, whenever the interceptor moves to the left, it can block and push away the stones on the lawn, preventing the stones on the lawn from colliding with the electric cutter and causing damage to the electric cutter, thus ensuring the safety of the electric cutter.

The slotted plate 9 is inclined and contacts the triggering component. The slotted plate 9 is used to drive the triggering component to operate. The triggering component drives the electric cutter 12 to move horizontally, so that the electric cutter 12 can flexibly adjust the cutting width. A blowing component is provided between the telescopic plate 4 and the electric rotating shaft 10. When the blowing component operates, it can blow the cut grass into the collection box 2.

[0033] Please see Figure 3 and Figure 4As shown, the trigger assembly includes a movable tube 13, a trigger frame 131, an n-shaped rod 132, a swing frame 133, and a contact rod 134. The swing frame 133 is rotatably connected to the upper left side of the electric cutter 12, and the n-shaped rod 132 is rotatably connected to the upper part of the rotating frame 11. The upper part of the n-shaped rod 132 is rotatably connected to the upper part of the swing frame 133. When the n-shaped rod 132 swings downward, it can drive the swing frame 133 to move. The lower part of the n-shaped rod 132 has symmetrically arranged waist-shaped holes 1321. The movable tube 13 is slidably fitted onto the lower part of the outer side of the housing 8. The trigger frame 131 is fixedly fitted onto the lower part of the outer side of the movable tube 13. The front and rear ends of the trigger frame 131 are slidably connected to the front and rear waist-shaped holes 1321 respectively. The upper part of the outer side of the movable tube 13 is symmetrically fixed to the left and right sides. The left and right contact rods 134 are slidably connected to the left and right side slotted plates 9 respectively.

[0034] Please see Figure 5 and Figure 6As shown, the blowing assembly includes a telescopic nozzle 14, an air outlet pipe 141, a fan blade 142, an air extraction pipe 143, a fixed housing 144, a mesh plate 145, and a pushing assembly. The telescopic nozzle 14 is fixedly connected between the lower left sides of the telescopic plates 4 on both the front and rear sides. The air outlet end of the telescopic nozzle 14 faces to the right. The telescopic nozzle 14 can blow air to blow the cut grass. Both the front and rear ends of the telescopic nozzle 14 are connected to the air outlet pipe 141. The tail ends of the air outlet pipes 141 on both the front and rear sides pass through the mounting plate 3 and communicate with the inside of the housing 8. The upper part of the electric rotating shaft 10 is fixed. The housing 8 is equipped with fan blades 142. When the fan blades 142 rotate, they blow air into the exhaust pipe 141. A suction pipe 143 is symmetrically connected to the upper right side of the housing 8, with its outlet located below the fan blades 142. The tail ends of the suction pipes 143 on both sides pass through the mounting plate 3. A fixed shell 144 is fixedly connected to the top of the collection box 2. The left side of the fixed shell 144 is connected to the tail ends of the suction pipes 143 on both sides. A mesh plate 145 is fixedly connected to the lower inner side of the fixed shell 144, allowing the collected air to pass through the mounting plate 3. The grass inside box 2 is blocked. A pushing assembly is located on the lower right side of the front and rear telescopic plates 4. When the pushing assembly operates, it can push the grass to the right into the elastic cover 6. The pushing assembly includes a telescopic conveying roller 146, a belt assembly 147, and a telescopic guide plate 148. The telescopic conveying roller 146 is rotatably connected between the lower right sides of the front and rear telescopic plates 4. When the telescopic conveying roller 146 reverses, it can drive the cut grass to the right. The front end of the telescopic conveying roller 146 is connected to the axle of the front right wheel 5. A belt assembly 147 is connected between the parts. The belt assembly 147 consists of a large pulley, a small pulley, and a flat belt. The large pulley is fixedly mounted on the axle of the wheel 5, and the small pulley is fixedly mounted on the front end of the telescopic conveyor roller 146. The flat belt is wound between the large pulley and the small pulley. A telescopic guide plate 148 is fixedly connected between the lower right side of the inner side of the telescopic plates 4 on both the front and rear sides. The telescopic guide plate 148 is located on the right side of the telescopic conveyor roller 146 and is inclined. The telescopic guide plate 148 can guide the cut grass.

[0035] First, the operator holds the movable frame 1, and then pushes the device onto the lawn using the movable frame 1 and wheels 5. The rubber sleeve 101 contacts the operator's hand, increasing friction and allowing the operator to grip the movable frame 1 more firmly. At this time, the electric cutter 12 contacts the grass on the lawn. Then, depending on the condition of the lawn, the left and right cylinders 7 are activated. The extension rods of the left and right cylinders 7 extend, respectively driving the front and rear extension plates 4 to move outward. The front and rear extension plates 4 drive the extension nozzle 14, extension conveyor roller 146, and extension guide plate 148 to extend. At the same time, the outward movement of the front extension plate 4 drives the straight perforated plate 9 to move forward. The forward movement of the straight perforated plate 9 drives the contact rod 134 to move downward. The downward movement of the contact rod 134 drives the movable tube 13 to move downward. The downward movement of pipe 13 causes the trigger frame 131 to move downward. The downward movement of trigger frame 131, through the oblong hole 1321, causes the n-shaped rod 132 to swing downward. The downward swing of n-shaped rod 132 causes the swing frame 133 to swing downward. The downward swing of swing frame 133 causes the electric cutter 12 to move to the left. The leftward movement of electric cutter 12 adjusts the width of grass cutting. Electric cutter 12 moves synchronously with the movement of the front and rear telescopic plates 4 to prevent the electric cutter 12 from colliding with the telescopic plates 4 after the position is adjusted, thus affecting the use of the telescopic plates 4. When the electric cutter 12 is adjusted to the required width of grass cutting, cylinder 7 is closed, and the front and rear telescopic plates 4 stop moving outward. At this time, the telescopic plates 4 are in the appropriate position for use. Telescopic spray pipe 14, telescopic material conveyor Roller 146 and telescopic guide plate 148 stop extending, front telescopic plate 4 stops driving the perforated plate 9 to move forward, perforated plate 9 stops driving contact rod 134 to move downward, contact rod 134 stops driving movable tube 13 to move downward, and electric cutter 12 stops moving to the left. Then, electric cutter 12 starts rotating forward, and electric shaft 10 starts rotating forward at the same time. Protective cover 102 protects the upper part of electric shaft 10 to prevent electric shaft 10 from being damaged by foreign debris, thus ensuring the safety of electric shaft 10 in use. The forward rotation of electric shaft 10 drives rotating frame 11 to rotate forward, and rotating frame 11 drives electric cutter 12 to perform circular motion. Electric cutter 12 rotates forward and moves in a circular motion to cut the grass on the lawn. The operator can then move the frame 1 to cut the grass. As wheel 5 propels the device to the left, the electric cutter 12 moves to the left for full mowing. During mowing, the front right wheel 5 reverses, causing the belt assembly 147 to reverse, which in turn causes the telescopic conveyor roller 146 to reverse. Simultaneously, the electric shaft 10 rotates forward, also causing the fan blade 142 to rotate forward. The fan blade 142 blows air into the air outlet pipe 141, which then discharges the air into the telescopic nozzle 14. The telescopic nozzle 14 blows the air to the right, where it contacts the cut grass. The air propels the cut grass to the right, where it contacts the telescopic conveyor roller 146. The telescopic conveyor roller 146 then reverses, pushing the cut grass to the right until it contacts the telescopic guide plate 148.The telescopic guide plate 148 guides the cut grass into the elastic cover 6. Simultaneously, the fan blade 142 rotates clockwise, drawing air from the fixed housing 144 and the collection box 2 through the exhaust pipe 143, creating a negative pressure in the collection box 2. This draws the grass out of the elastic cover 6, collecting it for subsequent processing. The mesh plate 145 blocks the grass in the collection box 2, preventing it from flowing through the fixed housing 144 into the exhaust pipe 143 and causing blockage, thus ensuring the normal operation of the exhaust pipe 143. This process is repeated to continuously cut and collect the grass on the lawn. Once all the grass on the lawn has been cut, the electric cutter 12 and the electric shaft 10 are turned off. The electric shaft 10 stops driving the rotating frame 11 to rotate clockwise, and the rotating frame 11 stops driving the electric cutter 12 to rotate in a circular motion. The electric shaft 10 also stops driving the electric cutter 12 to rotate in a circular motion. When the fan blade 142 rotates forward, air stops being discharged into the exhaust pipe 141, and the telescopic nozzle 14 stops expelling air. At the same time, the fan blade 142 stops evacuating air from the fixed housing 144 and the collection box 2 through the extraction pipe 143, thus stopping the device. The wheel 5 stops reversing, and the wheel 5 stops driving the telescopic conveying roller 146 to reverse. Then, the cylinders 7 on both sides are activated to drive the telescopic plates 4 on both sides to move inward and reset. The reset of the front telescopic plate 4 drives the straight hole plate 9 to move backward and reset. The reset of the straight hole plate 9 drives the contact rod 134 to move upward and reset. The contact rod 134 drives the trigger frame 131 to move upward and reset through the movable tube 13. The trigger frame 131 drives the n-shaped rod 132 to swing upward and reset through the waist-shaped hole 1321. The n-shaped rod 132 drives the electric cutter 12 to move to the right and reset through the swing frame 133. At the same time, the telescopic plate 4 drives the telescopic nozzle 14, the telescopic conveying roller 146, and the telescopic guide plate 148 to retract and reset. Thus, by adjusting the positions of the telescopic plate 4 and the electric cutter 12, the mowing width can be flexibly adjusted to suit different lawn conditions, thereby improving adaptability and overall mowing efficiency.

[0036] Please see Figure 7 and Figure 8As shown, the lithium-ion lawn mower for garden lawns also includes a blocking assembly installed between the left sides of the front and rear telescopic plates 4. The blocking assembly includes a blocking frame 15, an L-shaped block 151, a swing block 152, a connecting spring 153, and a drive assembly. The blocking frame 15 is rotatably connected between the lower left sides of the inner sides of the front and rear telescopic plates 4. The front blocking frame 15 and the rear blocking frame 15 are slidably connected. The blocking frame 15 can block stones in the lawn. The front side of the front blocking frame 15 and the rear side of the rear blocking frame 15 are both fixedly connected to the L-shaped block 151. The lower left side of the outer side of the front and rear telescopic plates 4 is rotatably connected to the swing block 152. The lower left side of the swing block 152 is connected to the front and rear sides respectively. A connecting spring 153 is connected between the lower right side of the L-shaped block 151 and the swing block 152. A drive assembly is provided between the swing block 152 and the telescopic plate 4. When the drive assembly is in operation, it can drive the swing block 152 to swing to the left. The drive assembly includes a button 154 and an electric push rod 155. A button 154 is installed on the lower left side of the swing block 152 on both the front and rear sides. The button 154 corresponds to the L-shaped block 151. An electric push rod 155 is rotatably connected to the lower left side of the outer side of the telescopic plate 4 on both the front and rear sides. The telescopic rod ends of the electric push rods 155 on both the front and rear sides are rotatably connected to the lower part of the swing block 152 on both the front and rear sides. The electric push rod 155 and the button 154 are electrically connected through a control module.

[0037] When the telescopic plates 4 on both sides move outward, they drive the front and rear interceptor frames 15 to move outward. When the telescopic plates 4 stop moving, they stop driving the front and rear interceptor frames 15 to move outward. When the operator pushes the device to the left, the telescopic plates 4 move to the left, driving the front and rear interceptor frames 15 to move to the left. The front and rear interceptor frames 15 move to the left and move within the grass. When the front and rear interceptor frames 15 move to the left and come into contact with stones in the grass, the interceptor frames 15 block the stones. As the stones are continuously blocked, the weight of the stones compresses the interceptor frames 15, causing them to swing to the right. The swing of the interceptor frames 15 to the right causes the L-shaped block 151 to swing to the right, compressing the connecting spring 153. When the L-shaped block 151 swings to the right, it interacts with the button 15. When contact is made, L-shaped block 151 presses button 154. Button 154 controls the electric push rod 155 to start via the control module. The telescopic rod of the electric push rod 155 quickly extends, causing the swing block 152 to swing rapidly to the left. The swing block 152, through the connecting spring 153, causes the interceptor frame 15 to swing to the left. The leftward swing of the interceptor frame 15 quickly pushes away the blocking stones, and the stones lose contact with the interceptor frame 15. Due to the action of the connecting spring 153, the interceptor frame 15 swings back to its original position. Subsequently, the telescopic rod of the electric push rod 155 shortens, causing the swing block 152 to swing back to the right. The swing block 152, through the connecting spring 153, causes the interceptor frame 15 to swing back to the right. At this time, the interceptor frame 15 is in its initial position and continues to block the stones on the lawn. When the telescopic plate 4 stops moving to the left, the telescopic plate 4 stops causing the interceptor frame 15 to move to the left. At the same time, when the telescopic plates 4 on both sides move inward to reset, the telescopic plate 4 causes the interceptor frames on both sides to move inward to reset, and then the grass in the collection box 2 is taken out for further processing. This prevents stones on the lawn from colliding with the electric cutter 12 and causing damage to the electric cutter 12, thus ensuring the safety of the electric cutter 12.

[0038] Please see Figure 9 As shown, the lithium-ion lawn mower for garden lawns also includes a guide frame 16 and a breathable collection bag 17. The guide frame 16 is fixed to the left side of the collection box 2, and the breathable collection bag 17 is snapped into the discharge end of the guide frame 16. The breathable collection bag 17 can collect the cut grass in a concentrated manner.

[0039] When the collection box 2 is under negative pressure, it creates negative pressure inside the breathable collection bag 17, which in turn creates negative pressure inside the guide frame 16. The grass inside the elastic cover 6 is drawn into the guide frame 16, and then into the breathable collection bag 17. The cut grass is collected in the breathable collection bag 17. After all the grass on the lawn has been cut, the door of the collection box 2 is pulled upwards to open, and the breathable collection bag 17 is removed from the guide frame 16 to empty the cut grass. After all the cut grass has been emptied, the breathable collection bag 17 is clipped back onto the guide frame 16. This makes it easier to collect the cut grass.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
