Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically an electric five-section rotary lawnmower. Background Technology

[0002] A rotary lawnmower is a device used for mowing lawns. It works by rotating a device consisting of several fixed-length blades arranged in a curved pattern on the surface of a cylinder, which cuts the grass against a fixed blade. Some lawns have slopes or uneven surfaces, requiring adjustment of the blade's cutting angle to conform to the grass and create a smoother surface. The blade must also automatically reset during this process to prevent uneven mowing. Furthermore, battery pack replacement is difficult because the heavy battery pack is usually too heavy for one person to lift onto the vehicle. Therefore, multiple people are typically needed to continuously mow the lawn, which is inconvenient.

[0003] Chinese patent CN119655048A discloses a pure electric new energy rotary lawnmower, including a frame, a drive system, a lithium battery power system, a control panel, and a mowing system. The frame adopts a modular design. The drive system is used to drive the frame and the mowing system. The lithium battery power system is used to improve the equipment's range and provide stable power output. The control panel is used by the operator to control the mowing speed and the rotation speed of the mowing blades. The mowing system is used to trim the corresponding lawn. The lithium battery power system consists of a lithium battery pack. The mowing system includes a front right rotary blade, a front left rotary blade, and a rear rotary blade. The front right and front left rotary blades are distributed on the left and right sides of the front end of the frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the lifting component of the multi-angle support mechanism to drive the self-swinging component to move towards the grass, the self-swinging component to drive the mowing and discharging mechanism to move towards the grass, the connecting frame of the self-swinging component to move towards the grass to drive the swing frame to move towards the grass, the swing frame to move towards the grass to drive the mowing and discharging mechanism to move towards the grass, the mowing and discharging mechanism is close to the grass, so that the swing frame follows the mowing and discharging mechanism to swing left and right and back and forth, and to trim the grass in the front and back and left and right directions. When swinging back and forth, the swing frame swings back and forth on the connecting frame, causing the guide rod to move. The movement of the guide rod causes the spring to undergo elastic deformation. The spring resets the back and forth swing of the mowing and discharging mechanism, so that it can move to fit the grass plane for easy grass trimming. This is beneficial for the equipment to fit the grass in the front and back and left and right directions for trimming. 2. The blades and curved brackets are used to trim weeds on the lawn. By rotating the threaded rod, the threaded rod moves on the threaded sleeve, allowing the curved bracket to rotate and adjust the gap between itself and the blades, thus better cutting the weeds. The cut weeds fall to the position of the spiral blades. The output shaft of the second drive motor rotates, driving the spiral blades to rotate. The spiral blades discharge the weeds to the left and right sides of the vehicle body, avoiding interference with subsequent trimming and facilitating the cleanup of the weeds. Open the sealed door, separate the battery pack connector from the vehicle body connector, pull out the sliding frame, and at the same time, the output end of the electric hoist extends. The auxiliary roller assists in the movement of the sliding frame. When the sliding frame moves to the ground, the roller moves to the end of the slot and is limited and cannot move further. The sliding frame, the box, and the ground form a triangle, which is relatively stable. At this time, loosen the straps on the battery pack, replace it with a new battery pack, tie the straps back on, and the output end of the electric hoist shortens, causing the sliding frame to move upward. The operator assists in moving the sliding frame into the box, connects the battery pack connector to the vehicle body connector, closes the sealed door, and locks the buckle to complete the battery pack replacement. This facilitates quick battery pack replacement. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to... Figure 1 The direction of the viewpoint.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 The electric five-section rotary lawnmower includes a vehicle body 1, and also includes: a multi-angle support mechanism 2, a mowing and discharge mechanism 3, and a battery pack quick-change mechanism 4. The vehicle body 1 is equipped with multiple multi-angle support mechanisms 2 for elastically conforming to the grass. The multi-angle support mechanisms 2 are equipped with a mowing and discharge mechanism 3 for continuously mowing and discharging broken grass to one side. The battery pack quick-change mechanism 4 is installed in the middle of the vehicle body 1 for quickly popping out and replacing the battery pack.

[0014] The multi-angle support mechanism 2 includes a lifting component and a self-swinging component. Multiple lifting components are installed on the lower side of the vehicle body 1, and the self-swinging component is installed at the output end of the lifting component.

[0015] The grass cutting and discharge mechanism 3 includes a grass cutting component and a discharge component. The grass cutting component is installed in the middle of the multi-angle support mechanism 2, and the discharge component is installed on one side of the multi-angle support mechanism 2.

[0016] The lifting assembly includes a swing frame 21, an electric push rod 22, and a torsion spring 23. One end of the swing frame 21 is rotatably connected to the lower side of the vehicle body 1 via a rotating shaft. The fixed end of the electric push rod 22 is rotatably connected to the lower side of the vehicle body 1 via a rotating shaft. The output end of the electric push rod 22 is slidably connected to the end of the swing frame 21 away from the vehicle body 1. The torsion spring 23 is sleeved on the rotating shaft of the swing frame 21. One end of the torsion spring 23 is fixedly connected to the swing frame 21, and the other end of the torsion spring 23 is fixedly connected to the vehicle body 1.

[0017] The extension of the output end of the electric push rod 22 of the lifting component of the multi-angle support mechanism 2 drives the swing frame 21 to rotate downward. At this time, the torsion spring 23 undergoes elastic deformation. The downward rotation of the swing frame 21 drives the self-swinging component to move towards the grass. The movement of the self-swinging component towards the grass drives the mowing and discharging mechanism 3 to move towards the grass. The mowing and discharging mechanism 3 starts to mow the grass. After mowing, the output end of the electric push rod 22 shortens, driving the swing frame 21 to rotate upward. At this time, the torsion spring 23 returns to its original position. The upward rotation of the swing frame 21 drives the self-swinging component to move away from the grass. The movement of the self-swinging component away from the grass drives the mowing and discharging mechanism 3 to move away from the grass, thus achieving lifting and lowering. The torsion spring 23 is used to assist in resetting the mowing and discharging mechanism 3. At the same time, it can prevent the mowing and discharging mechanism 3 from falling to the ground due to the failure of the electric push rod 22. Moving the machine to repair it at this time may cause the mowing and discharging mechanism 3 to be damaged by contact with the ground. This is beneficial for the automatic lifting and lowering of the mowing and discharging mechanism 3.

[0018] The self-oscillating assembly includes: a connecting frame 24, an oscillating frame 25, guide rods 26, and a spring 27. The connecting frame 24 is rotatably connected to the side of the oscillating frame 21 away from the vehicle body 1. The oscillating frame 25 is rotatably connected to the side of the connecting frame 24 away from the oscillating frame 21. One end of each guide rod 26 is rotatably connected to the connecting frame 24 via a pivot. The end of each guide rod 26 away from the connecting frame 24 is slidably connected to the oscillating frame 25. The spring 27 is sleeved on the guide rod 26. One end of the spring 27 is in close contact with the connecting frame 24, and the other end of the spring 27 is in close contact with the oscillating frame 25.

[0019] The downward rotation of the swing frame 21 drives the connecting frame 24 of the self-swinging assembly to move towards the grass. The movement of the connecting frame 24 towards the grass drives the swing frame 25 towards the grass. The movement of the swing frame 25 towards the grass drives the mowing and feeding mechanism 3 towards the grass. The mowing and feeding mechanism 3 is close to the grass, so that the swing frame 25 swings left and right and back and forth with the mowing and feeding mechanism 3. When swinging back and forth, the swing frame 25 swings back and forth on the connecting frame 24, causing the guide rod 26 to move. The movement of the guide rod 26 causes the spring 27 to undergo elastic deformation. The spring 27 resets the back and forth swing of the mowing and feeding mechanism 3, so that it can fit the grass plane when moving, which is convenient for mowing the grass.

[0020] The mowing assembly includes a rotary mowing assembly and a support assembly. The rotary mowing assembly is installed in the middle of the swing frame 25, and the support assembly is installed on one side of the swing frame 25.

[0021] The rotary mowing assembly includes: a blade 31, a first drive motor 32, an arc-shaped bracket 33, a threaded sleeve 34, and a threaded rod 35. The blade 31 is rotatably connected to the swing frame 25 via a rotating shaft. The first drive motor 32 is fixedly installed on the side wall of the swing frame 25, and the output shaft of the first drive motor 32 is fixedly connected to the rotating shaft of the blade 31. The two arc-shaped brackets 33 are symmetrically distributed on the left and right sides of the swing frame 25. The lower side of the arc-shaped bracket 33 is rotatably connected to the swing frame 25 via a rotating shaft. The threaded sleeve 34 is rotatably connected to the swing frame 25 via a rotating shaft. One end of the threaded rod 35 is threadedly connected to the threaded sleeve 34, and the end of the threaded rod 35 away from the threaded sleeve 34 is rotatably connected to the upper side of the arc-shaped bracket 33 via a rotating shaft.

[0022] The support assembly includes a support frame 36 and a guide wheel 37. The support frame 36 is fixedly mounted on the swing frame 25, and the guide wheel 37 is rotatably connected to the support frame 36 via a rotating shaft.

[0023] The discharge assembly includes a spiral blade 38 and a second drive motor 39. The spiral blade 38 is rotatably connected to the swing frame 25 via a rotating shaft. The second drive motor 39 is fixedly installed on the side wall of the swing frame 25, and the output shaft of the second drive motor 39 is fixedly connected to the rotating shaft of the spiral blade 38.

[0024] The swing frame 25 moves towards the grass, causing the mowing and feeding mechanism 3 to move towards the grass. The mowing and feeding mechanism 3 is close to the grass. The support frame 36 and guide wheel 37 of the mowing assembly move towards the grass. The guide wheel 37 contacts the grass, reducing the friction when the mowing and feeding mechanism 3 moves. The output shaft of the first drive motor 32 of the rotating mowing assembly rotates, causing the blade 31 to rotate. The rotation of the blade 31 cooperates with the arc-shaped bracket 33, allowing the grass on the grass to enter between the blade 31 and the arc-shaped bracket 33 and be cut. By rotating the threaded rod 35, the threaded rod 35 moves on the threaded sleeve 34, allowing the arc-shaped bracket 33 to rotate to adjust the gap between it and the blade 31, thereby better cutting weeds. The cut waste grass falls to the position of the spiral blade 38. The output shaft of the second drive motor 39 rotates, causing the spiral blade 38 to rotate. The rotation of the spiral blade 38 discharges the waste grass to the left and right sides of the vehicle body 1, avoiding affecting subsequent mowing and facilitating the cleaning of waste grass.

[0025] Example 2: In some embodiments, such as Figures 1-8In a preferred embodiment of this utility model, the battery pack quick-change mechanism 4 includes: an auxiliary replacement component and a drive component. The auxiliary replacement component is installed on the rear side of the vehicle body 1, and the drive component is installed on the auxiliary replacement component. The auxiliary replacement component includes: a housing 41, a sliding frame 42, rollers 43, and an auxiliary roller 44. The housing 41 is fixedly installed on the rear side of the vehicle body 1. The housing 41 has slots 45 on its left and right sides. The sliding frame 42 is slidably connected inside the housing 41. Multiple metal springs 46 are fixedly installed on the side wall of the housing 41 to limit the left and right directions of the sliding frame 42 inside the housing 41 to prevent shaking. The left and right sides of the sliding frame 42 are rotatably connected to rollers 43 through a rotating shaft. The rollers 43 are located on the side of the sliding frame 42 closest to the front side wall of the housing 41 and are located inside the slots 45, where they can roll. The auxiliary roller 44 is rotatably connected to the rear side of the housing 41 through a rotating shaft, and the rear side of the sliding frame 42 is located on the auxiliary roller 44.

[0026] The drive assembly includes an electric hoist 47, which is fixedly installed on the front side of the housing 41, and the output end of the electric hoist 47 is fixedly installed on the front side wall of the sliding frame 42.

[0027] The battery pack quick-change mechanism 4 further includes a sealing assembly, which is installed on the front side of the housing 41. The sealing assembly includes a sealing door 48 and a latch 49. The sealing door 48 is rotatably connected to the rear side of the housing 41 via a pivot, and multiple latches 49 are fixedly installed on the sealing door 48.

[0028] When replacing the battery pack, due to its weight, it is usually impossible for one person to lift it onto the vehicle body 1. Open the latch 49 of the sealing component of the battery pack quick-change mechanism 4, open the sealing door 48, separate the battery pack connector from the vehicle body 1 connector, pull out the sliding frame 42, and at the same time, the output end of the electric hoist 47 extends. The auxiliary roller 44 assists in the movement of the sliding frame 42. When the sliding frame 42 moves to contact the ground, the roller 43 moves to the end of the slot 45 and is limited and cannot move. The sliding frame 42, the housing 41 and the ground form a triangle, which is relatively stable. At this time, loosen the strap on the battery pack, replace it with a new battery pack, tie the strap back on, and the output end of the electric hoist 47 shortens, driving the sliding frame 42 to move upward. The operator assists the sliding frame 42 to move into the housing 41, connects the battery pack connector to the vehicle body 1 connector, closes the sealing door 48, and locks the latch 49 to complete the battery pack replacement. This facilitates quick battery pack replacement.
