Technical Field
[0001] The invention relates to the field of lawn mowing devices, and in particular to an intelligent remote-controlled all-electric lawn mowing robot. Background Art
[0002] As living standards continue to improve, people's requirements for living environment are also increasing, so lawn greening is becoming more and more important. Traditional types of mowing equipment mainly include backpack mowers, push mowers, etc.
[0003] However, most traditional mowing equipment requires manual assistance to operate, especially for large-scale mowing operations. Operators are tired from walking for a long time, and the mowing cost is high and the efficiency is low. Therefore, smart mowing robots have become a new development trend of mowing equipment. In terms of power source, most existing mowing equipment is powered by fuel, which has strong power and can effectively ensure the mowing effect, but there are environmental problems and safety hazards of fuel, as well as the disadvantage of additional weight.
[0004] With regard to the above-mentioned related technologies, most lawn mowing robots use cruise control, random collision and other methods to mow the grass. However, when mowing the grass in a natural environment, the mowing head of the lawn mowing robot is prone to collision with harder objects such as stones and trees, causing damage. Therefore, an electric lawn mowing robot is urgently needed to solve the above problems. Summary of the invention
[0005] In order to reduce the probability of a mowing head being damaged due to collision with external objects, the present application provides an intelligent remote-controlled fully electric mowing robot.

[0007] By adopting the above technical solution, the battery supplies power to the brushless motor, and the operator controls the brushless motor to work through the remote control component, so that the brushless motor drives the frame to move through the walking mechanism. When the frame moves, all mowing heads are driven to move through the support frame 1 and the support frame 2, and the brushless motor connected to the mowing head drives the mowing head to work, and then the mowing head is used to harvest. When harvesting lawns of different lengths, the support frame 1 is driven to move through the adjustment mechanism, and then the height of all mowing heads along the vertical direction is adjusted. When one end of the mowing head installed on any frame approaches a relatively solid object, the protection frame first contacts the object. At this time, the protection frame connected to the support frame 1 protects the corresponding mowing head and prevents the frame from approaching the object. When the protection frame connected to the support frame 2 contacts the object, if the frame continues to move forward, the support frame 2 drives the corresponding protection frame and the mowing head to rotate like the frame, and then avoids the object. At this time, the elastic member is deformed, thereby preventing the mowing head from directly colliding with external objects, protecting the mowing head, and reducing the probability of damage to the mowing head when working.
[0008] Optionally, the adjusting mechanism includes a rotating ring, a lifting frame and an adjusting cylinder. The lifting frame is rotatably connected to the frame vertically, a supporting frame is connected to one end of the lifting frame away from the frame and moves with the lifting frame, two parallel plates are fixedly connected to the lower end of the frame, a rotating rod is fixedly connected between the two plates, the rotating ring is sleeved on the outside of the rotating rod and is rotatably connected to the rotating rod, the adjusting cylinder is fixedly connected to the rotating ring, a support rod parallel to the rotating rod is fixedly connected to the lower end of the lifting frame, a connecting ring is fixedly connected to the output end of the adjusting cylinder, the support rod passes through the connecting ring and is rotatably connected to the connecting ring.
[0009] By adopting the above technical solution, the frame supports the rotating ring through the flat plate and the rotating rod, and the rotating ring position adjusting cylinder provides support. When the output end of the adjusting cylinder moves, the supporting rod is driven to move through the connecting ring, and then the lifting frame is pushed to move, so that the lifting frame drives the supporting frame to move vertically, which is convenient for the vertical adjustment of the mowing head.
[0010] Optionally, a mounting plate is provided on the upper end of support frame 1 and support frame 2, and the mowing head includes a connecting shaft, a connecting disk and a plurality of blades. The connecting shaft passes through the mounting plate and is rotatably connected to the mounting plate. The brushless motor is arranged at the upper end of the mounting plate and is used to drive the connecting shaft to rotate. The connecting disk is coaxially arranged at the lower end of the connecting shaft. The plurality of blades are circumferentially arranged along the connecting disk. The connecting disk is fixedly connected to a plurality of support plates along the circumference. The support plate is provided with a movable groove adapted to the blade. The blade is located in the movable groove. The support plate is vertically provided with a rotating shaft, which passes through the blade and is rotatably connected to the blade.
[0011] By adopting the above technical solution, under the support of the mounting plate, the brushless motor drives the connecting shaft to rotate when working, and the connecting shaft drives the connecting disk to rotate when rotating. The connecting disk drives the blade to move through the supporting plate and the rotating shaft, so that all the blades rotate around the connecting shaft. At this time, the blade drives the blade to open under the action of centrifugal force, and then mows the grass through the rotating blade. When the blade collides with a hard object, it rotates along the moving groove, and then avoids the hard object, which is beneficial to protect the blade.
[0012] Optionally, the protective frame includes two vertical plates and a baffle, the two groups of vertical plates are vertically arranged at the lower end of the mounting plate, and the spacing between the two mounting plates is smaller than the diameter of the mounting plate. An accommodating opening is opened at one end of the mounting plate close to the frame, the connecting plate and the blade are both located in the accommodating opening, and the baffle is vertically arranged between the two vertical plates.
[0013] By adopting the above technical solution, the two vertical plates cooperate to protect the connecting plate in the accommodating port and prevent hard foreign objects from approaching the connecting plate. The baffle blocks the gap between the two vertical plates along the horizontal direction, thereby reducing the probability of foreign objects passing through the two vertical plates and colliding with the connecting plate or the blade.
[0014] Optionally, the lower end of the mounting plate is fixedly connected to a support tube, the connecting shaft passes through the support tube and is rotatably connected to the support tube, the connecting plate is fixedly connected to one end of the support tube close to the support tube, the turntable has a plurality of movable openings along the circumferential direction, the lower end of the support tube is fixedly connected to a positioning ring, and the positioning ring is fixedly connected to a plurality of cutting blades along the circumferential direction.
[0015] By adopting the above technical solution, the support tube is conducive to improving the supporting stability of the mounting plate to the connecting shaft. When the connecting shaft rotates, it drives the turntable to rotate. When grass stems are wrapped around the outside of the connecting shaft, the turntable drives the grass stems to move through the moving port, so that the grass stems rotate around the connecting shaft and approach the cutting blade, so that the cutting blade cuts and divides the grass stems, which is conducive to reducing the probability of the grass stems affecting the rotation of the connecting shaft.
[0016] Optionally, the walking mechanism includes two driving wheels, a steering wheel, two walking motors and two gearboxes. The two driving wheels are located at the lower end of the frame and are rotatably connected to the frame. The two walking motors correspond to the two driving wheels respectively and are fixedly connected to one side of the frame close to the corresponding driving wheels. The gearbox is located between the driving wheels and the walking motors. The walking motors drive the driving wheels to rotate via the gearbox. A cross plate is fixedly connected to one end of the frame away from the supporting frame, and the cross plate is rotatably connected to a mounting frame for supporting the steering wheel along the transverse direction.
[0017] By adopting the above technical solution, the cross plate supports the steering wheel through the mounting frame, so that the steering wheel cooperates with the driving wheel to support the frame. When the travel motor drives the driving wheel to rotate through the gearbox, the driving wheel cooperates with the steering wheel to drive the frame to move.
[0018] Optionally, the cross plate is fixedly connected with a connecting tube along the vertical direction, and the upper end of the connecting tube is fixedly connected with an extension column, the mounting frame includes an adjusting frame and a rotating shaft, the rotating shaft is fixedly connected to the upper end of the adjusting frame, the steering wheel is located at the lower end of the adjusting frame and is rotatably connected to the adjusting frame, the rotating shaft passes through the connecting tube and is rotatably connected to the connecting tube, and the upper end of the rotating shaft is fixedly connected to a limiting disk, the extension column is provided with a rotating hole adapted for the limiting disk, the limiting disk is located in the rotating hole, and the height of the rotating hole along the axial direction is greater than the thickness of the limiting disk, a movable ring is provided at the lower end of the connecting tube, a shock-absorbing spring is provided between the movable ring and the adjusting frame, the shock-absorbing spring is sleeved on the outside of the rotating shaft, and one end of the shock-absorbing spring abuts against the movable ring, and the other end abuts against the adjusting frame.
[0019] By adopting the above technical solution, the horizontal plate supports the rotating shaft through the connecting pipe, so that the rotating shaft rotates around its own axis. When the rotating shaft rotates, the steering wheel is driven to rotate through the adjusting frame, so as to facilitate the adjustment of the steering wheel angle. When the rotating shaft rotates, the limit plate is driven to rotate, and the extension column limits the limit plate through the rotating hole, so that the limit plate has a movable space along the axis direction of the rotating hole. When the frame is vibrated, the steering wheel and the adjusting frame drive the rotating shaft to move along the axis direction. At this time, under the limiting action of the moving ring and the adjusting frame, the shock-absorbing spring slows down the vibration generated by the frame, which is conducive to reducing the vibration borne by the frame.
[0020] Optionally, a power box is fixedly connected to the upper end of the frame, the power box is located between the driving wheel and the steering wheel, the battery is located inside the power box, a shield is hinged on the upper end of the power box, a connecting bolt is provided between the shield and the power box, and the connecting bolt passes through the shield and is threadedly connected to the power box.

At this time, the protection frame connected to support frame 1 protects the corresponding mowing head and prevents the frame from approaching the object. When the protection frame connected to support frame 2 contacts the object, if the frame continues to move forward, support frame 2 drives the corresponding protection frame and the mowing head to rotate like the frame, and then avoids the object.

DETAILED DESCRIPTION
[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0030] The embodiment of the present application discloses an intelligent remote-controlled all-electric lawn mowing robot.
[0031] Example: Reference Figure 1 and Figure 2 An intelligent remote-controlled all-electric lawn mowing robot includes a frame 1, the frame 1 is provided with a walking mechanism, a support frame 1 21, a support frame 22, three groups of mowing heads 4, multiple groups of brushless motors 14 and batteries for providing power to the brushless motors 14.
[0032] Reference Figure 2 and Figure 3 The travel mechanism includes a steering wheel 62, two driving wheels 61, two travel motors 63 and two gearboxes 64. The two driving wheels 61 are respectively rotatably connected to the two sides of the frame 1, thereby supporting the frame 1. The steering wheel 62 is located at one end of the frame 1. The frame 1 is fixed with a transverse plate 15 in the horizontal direction, and a connecting pipe 151 is fixed with the transverse plate 15 in the vertical direction. The connecting pipe 151 is provided with a through hole in the vertical direction, and an extension column 152 is fixed to the upper end of the connecting pipe 151. The extension column 152 is provided with a rotating hole 153 connected with the through hole, and the diameter of the rotating hole 153 is larger than the diameter of the through hole.
[0033] Reference Figure 2 and Figure 3The frame 1 is provided with a mounting frame 16, which includes an adjustment frame 161 and a rotating shaft 162. The rotating shaft 162 is fixedly connected to the upper end of the adjustment frame 161, and the rotating shaft 162 passes through the through hole and is rotatably connected to the connecting pipe 151. The connecting pipe 151 supports and limits the rotating shaft 162 in the circumferential direction through the through hole, so that the rotating shaft 162 drives the adjustment frame 161 to rotate around its own axis. An opening is provided at the lower end of the adjustment frame 161, and the steering wheel 62 is located in the opening and is rotatably connected to the adjustment frame 161. When the adjustment frame 161 moves, the steering wheel 62 is driven to move.
[0034] Reference Figure 2 and Figure 3 A limit plate 163 is fixed on the upper end of the rotating shaft 162. The limit plate 163 is located in the rotating hole 153. When the rotating shaft 162 rotates, the limit plate 163 is driven to rotate along the rotating hole 153. The height of the rotating hole 153 along the axial direction is greater than the thickness of the limit plate 163, so that the limit plate 163 and the rotating shaft 162 have a movable space along the axial direction. A moving ring 154 is fixed on the lower end of the connecting tube 151. A damping spring 155 is provided between the moving ring 154 and the adjusting frame 161. One end of the damping spring 155 abuts against the adjusting frame 161, and the other end pushes the moving ring 154 to abut against the connecting tube 151.
[0035] Reference Figure 1 and Figure 3 , the shock absorbing spring 155 is in a compressed state, thereby pushing the adjustment frame 161 away from the cross plate 15. At this time, the steering wheel 62 and the driving wheel 61 cooperate to support the frame 1, so that the frame 1 remains horizontal. The two travel motors 63 are respectively installed on both sides of the frame 1 along the width direction. The driving wheels 61 correspond to the travel motors 63 one by one. The gearbox 64 is installed inside the frame 1. The driving wheels 61 correspond to the gearbox 64. The travel motor 63 drives the driving wheels 61 to rotate through the gearbox 64, so that the two driving wheels 61 cooperate to drive the frame 1 to move. When the frame 1 vibrates, the steering wheel 62 drives the rotating shaft 162 to move along the axial direction through the adjustment frame 161. At this time, the shock absorbing spring 155 slows down the frame 1, reducing the vibration borne by the frame 1.
[0036] Reference Figure 1 and Figure 2A power box 11 is installed at the upper end of the frame 1, and a battery is fixedly connected to the power box 11. The projection of the power box 11 on the plane is located on the side of the driving wheel 61 away from the support frame 21. The battery and the power supply 11 cooperate to provide a counterweight for the support frame 21, thereby improving the stability of the support frame 21 when the frame 1 moves. The battery is electrically connected to the travel motor 63 to provide electrical energy for the travel motor 63. A shield 12 is provided at the upper end of the battery box. The shield 12 is hinged to the power box 11. When the shield 12 and the power box 11 are closed, the battery is protected, which is conducive to reducing the impact of external objects on the battery. The shield 12 is provided with a plurality of connecting bolts 13, and the connecting bolts 13 pass through the shield 12 and are threadedly connected to the power box 11, thereby pushing the shield 12 to fit with the power box 11, thereby improving the connection stability between the shield 12 and the power box 11.
[0037] Reference Figure 1 The frame 1 is provided with a remote control component, which is used to control the operation of the travel motor 63. The operator sends a control signal by operating the remote control component. The control signal is transmitted to the travel motor 63 via WIFI or Bluetooth to control the travel motor 63. Under the control of the remote control component, the operator does not need to move synchronously with the frame 1 when driving the frame 1 to move, which is beneficial to reducing the work intensity of the operator.
[0038] Reference Figure 1 and Figure 4 , frame 1 (reference Figure 1 ) A support frame 1 21 is provided at one end away from the horizontal plate 15, and the support frame 1 21 is slidably connected with the frame 1 in the vertical direction. When the frame 1 moves, the support frame 1 21 is driven to move. Two groups of support frames 2 22 are provided at one end of the support frame 1 21 away from the frame 1. The two groups of support frames 2 22 are respectively located on both sides of the support frame 1 21, and the support frames 2 22 are both hinged to the support frame 1 21. An elastic member 23 is provided between the support frame 2 22 and the support frame 1 21. The elastic member 23 is a spring, one end of which is connected to the support frame 1 21, and the other end is connected to the support frame 2 22. When the support frame 2 22 rotates in the direction close to the frame 1, the spring is in a stretched state, and thus has a tendency to drive the support frame 2 22 to reset.
[0039] Reference Figure 1 and Figure 5The frame 11 is provided with an adjustment mechanism 33, which includes a rotating ring 31, a lifting frame 32 and an adjustment cylinder 33. The lifting frame 32 is rotatably connected to the frame 1 in the vertical direction. The support frame 121 is located at the end of the lifting frame 32 away from the frame 1. A mounting bolt is provided between the support frame 121 and the lifting frame 32. The mounting bolt passes through the adjustment frame 161 and the support frame 121 in sequence and is threadedly connected with a nut. Under the cooperation of the mounting bolt and the nut, the lifting frame 32 moves and drives the support frame 121 to move. Two flat plates 17 are fixedly connected to the lower end of the frame 1. The two flat plates 17 are parallel to each other, and a rotating rod 171 is fixedly connected between the two flat plates 17. The rotating rod 171 is parallel to the rotating axis 162 of the lifting frame 32. The rotating ring 31 is sleeved on the outside of the rotating rod 171 and is rotatably connected to the rotating rod 171. The adjusting cylinder 33 is fixedly connected to the rotating ring 31. The frame 1 provides support for the adjusting cylinder 33 through the flat plate 17 and the rotating rod 171, so that the adjusting cylinder 33 rotates around the rotating rod 171.
[0040] Reference Figure 1 and Figure 5 The output end of the adjusting cylinder 33 is fixedly connected with a connecting ring 331, and the lower end of the lifting frame 32 is fixedly connected with a supporting rod 321 parallel to the rotating rod 171, and the supporting rod 321 passes through the connecting ring 331 and is rotatably connected with the connecting ring 331. Under the cooperation of the supporting rod 321 and the connecting ring 331, when the output end of the adjusting cylinder 33 moves, the lifting frame 32 is driven to move, and then the lifting frame 32 drives the supporting frame 1 21 to move, and the vertical height of the supporting frame 1 21 is adjusted.
[0041] Reference Figure 1 and Figure 4 The lower ends of the support frame 1 21 and the support frame 2 22 are both provided with a mowing head 4, and the mowing head 4 includes a connecting shaft 41, a connecting plate 42 and a plurality of blades 43. The support frame 1 21 and the support frame 22 are both provided with a mounting plate 24, and a supporting tube 241 is fixed vertically to the mounting plate 24, and the connecting shaft 41 passes through the supporting tube 241 and is rotatably connected to the supporting tube 241. The mounting plate 24 supports the connecting shaft 41 through the supporting tube 241, so that the supporting tube 241 supports the connecting shaft 41 to rotate around its own axis.
[0042] Reference Figure 1 and Figure 4A brushless motor 14 is installed at the upper end of the mounting plate 24. The brushless motor 14 is also electrically connected to the battery and is controlled by the remote control assembly. The brushless motor 14 is used to drive the connecting shaft 41 to rotate. A connecting disk 42 is coaxially fixed to the lower end of the connecting shaft 41. When the connecting shaft 41 rotates, the connecting disk 42 is driven to rotate. A plurality of support plates 421 are fixed to the connecting disk 42 along the circumferential direction. When the connecting disk 42 rotates, the support plates 421 are driven to move. The support plates 421 are all provided with moving grooves 422 in the horizontal direction. The moving grooves 422 correspond to the blades 43 one by one. The blades 43 are located in the corresponding moving grooves 422 and are rotatably connected to the support plates 421. The support plates 421 are provided with a rotating shaft 423 in the vertical direction. The rotating shaft 423 passes through one end of the blade 43 and is rotatably connected to the blade 43. When the support plate 421 moves, the blade 43 is driven to move through the rotating shaft 423.
[0043] Reference Figure 1 and Figure 4 The rotating shaft 423 supports the blade 43, so that the blade 43 rotates around the rotating shaft 423 in the moving groove 422. When the connecting plate 42 rotates, the blade 43 extends away from the connecting shaft 41 under the action of centrifugal force, and the lawn is cut when the blade 43 rotates. When mowing, if the blade 43 collides with a hard object, the blade 43 rotates under the support of the rotating shaft 423, so that the blade 43 avoids the object, thereby protecting the blade 43. When the blade 43 is damaged, it is also convenient to replace the blade 43.
[0044] Reference Figure 1 and Figure 4 , a protection frame 5 is provided under all mounting plates 24, and the protection frame 5 includes two vertical plates 51 and a baffle 52. The two vertical plates 51 are parallel to each other, and the connecting plate 42 and the rotating shaft 162 are both located between the two vertical plates 51. The vertical plates 51 are provided with a receiving opening 511 adapted to the connecting plate 42 and the blade 43. When the connecting plate 42 rotates, the blade 43 is driven to move in the receiving opening 511. The two vertical plates 51 cooperate to protect the connecting plate 42 and the blade 43. When the vehicle frame 1 drives the connecting plate 42 to approach a tree or a stone, the vertical plates 51 collide with it first, thereby preventing the blade 43 from colliding with an external object.
[0045] Reference Figure 1 and Figure 4The baffle plate 52 is fixedly connected between the two vertical plates 51, and the two vertical plates 51 cooperate to support and position the baffle plate 52, and the baffle plate 52 blocks the gap between the two vertical plates 51, thereby preventing a relatively narrow hard object from passing through the two vertical plates 51 and colliding with the blade 43. When the protection frame 5 connected to the support frame 22 collides with an external object, the support frame 22 rotates toward the frame 1 and avoids it. At this time, the elastic member 23 is in a stretched state, thereby preventing the mowing head 4 from directly colliding with an external object and protecting the mowing head 4.
[0046] Reference Figure 1 and Figure 4 A positioning ring 242 is fixed to the lower end of the support tube 241, and a plurality of cutting blades 243 are fixed to the positioning ring 242 along the circumferential direction. A turntable 424 is coaxially fixed to the upper end of the connecting disk 42, and the turntable 424 is coaxially arranged with the positioning ring 242. The turntable 424 is provided with a plurality of moving openings 425 along the circumferential direction. When grass stems are wound around the outside of the connecting shaft 41 during mowing, the turntable 424 drives the grass stems to rotate through the moving openings 425, and the grass stems rotate and collide with the cutting blades 243. At this time, the cutting blades 243 cut the grass stems, causing the grass stems to break, thereby helping to reduce the probability of the grass stems affecting the rotation of the connecting shaft 41.
[0047] The implementation principle of the intelligent remote-controlled all-electric lawn mower robot in the embodiment of the present application is as follows: the operator controls the walking motor 63 through the control component, so that the frame 1 drives the support frame 1 21 and the support frame 2 22 to move, and drives the connecting shaft 41 to rotate, so that the connecting plate 42 drives all the blades 43 to rotate. When the height of the support frame 1 21 needs to be adjusted, the lifting frame 32 is driven to rotate by adjusting the cylinder 33, so that the lifting frame 32 drives the support frame 1 21 to move vertically, thereby adjusting the vertical height of the mowing head 4. When mowing, the protection frame 5 protects the connecting plate 42 and the blade 43, thereby preventing foreign objects from colliding with the blade 43 or the connecting plate 42. Since the grass stem has a certain elasticity, when the baffle 52 collides with the grass stem, it drives the grass stem to bend, and the frame 1 continues to move forward. After the grass stem is reset, it enters the side of the baffle 52 close to the blade 43, and the blade 43 cuts the grass stem. When the protection frame 5 connected to the support frame 22 collides with an external obstruction, the support frame 22 rotates toward the frame 1 under the action of the thrust and drives the elastic member 23 to deform, thereby making the mounting plate 24 and the mowing head 4 avoid the obstruction, reducing the probability of damage to the mowing head 4 during operation.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
