Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0030] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In addition, the terms "first", "second", and the like are only used to distinguish description, and cannot be understood as indicating or implying relative importance.

[0032] Please refer to Figure 1 , Figure 2 The embodiments of the present application provide an intelligent mowing robot 10, which can be used for mowing grass on a lawn.

[0033] Among them, the intelligent mowing robot 10 is mainly composed of a main body 11, a walking assembly 12 and a mowing assembly 13, the walking assembly 12 and the mowing assembly 13 are arranged on the main body 11, and the structures of the parts of the intelligent mowing robot 10 will be discussed in detail below.

[0034] The shape and structure of the main body 11 are not limited, and can refer to the prior art, for example, a frame structure, which mainly serves the functions of mounting components, support, connection, etc., and the main body 11 can accommodate batteries, control systems, cameras, etc. The main body 11 can accommodate various conventional structures of robots.

[0035] The walking assembly 12 is mainly used to drive the main body 11 and the mowing assembly 13 to move forward, and the number, style and structure of the walking assembly 12 are not limited, for example, the number of the walking assembly 12 is one, two, three, four, etc., and the walking assembly 12 can adopt a track type structure or a wheel type structure, etc.

[0036] In the embodiment, please refer to the drawings shown in Figure 3 , Figure 4 , the number of the walking assembly 12 is four, and the four walking assemblies 12 are distributed in a rectangular shape. Each walking assembly 12 can be independently controlled and worked, or can work cooperatively. In this way, it is similar to a Mecanum wheel vehicle, and can realize omnidirectional steering and walking. The structure of each walking assembly 12 can adopt but is not limited to the following scheme: the walking assembly 12 includes a walking wheel 120, a damping assembly 121 and a walking motor 122.

[0037] The walking wheel 120 can adopt a common roller, a Mecanum wheel, a spherical wheel, etc., and is used to contact and rotate with the ground.

[0038] The walking wheel 120 is rotatably arranged on one side of the main body 11, and can be directly connected with the main body 11 or indirectly connected with the main body 11 through other structures, for example, the walking wheel 120 and the main body 11 are connected through a parallel four-bar linkage mechanism 123. The parallel four-bar linkage mechanism 123 refers to that the walking assembly 12 further includes a mounting bracket and two connecting pieces which can be plate-shaped, rod-shaped, block-shaped, etc. The two ends of the connecting pieces are respectively hinged with the main body 11 and the mounting bracket, and the walking wheel 120 is rotatably supported on the mounting bracket. The main body 11, the mounting bracket and the two connecting pieces jointly constitute the parallel four-bar linkage mechanism 123. When the walking wheel 120 encounters an obstacle, it can be adjusted up and down, and at this time, the parallel four-bar linkage mechanism 123 works to ensure the direction of the walking wheel 120.

[0039] The damping assembly 121 is connected with the main body 11 and the parallel four-bar linkage mechanism 123, respectively. When the walking wheel 120 moves up and down, the damping assembly 121 can play a buffering role, so as to make the main body 11 as stable as possible and not shake.

[0040] The structure of the damping assembly 121 is not limited, and can refer to the prior art, for example, a spring type damping structure, a liquid type damping structure, a gas cylinder type damping structure, a friction type damping structure, etc. In the embodiment, the damping assembly 121 can also adopt the following scheme: the damping assembly 121 includes a connecting rod 124, a damping triangular piece 125, a damping telescopic rod 126 and a damping spring 127.

[0041] The connecting rod 124 is in a rod-like or long strip plate-like structure, etc. One end of the connecting rod 124 is hingedly connected with one of the connecting pieces of the parallel four-bar linkage, and the other end is hingedly connected with the damping triangular piece 125. One end of the damping telescopic rod 126 is hingedly connected with the main body 11, and the other end is hingedly connected with the damping triangular piece 125. In addition to being hingedly connected with the connecting rod 124 and the damping telescopic rod 126, the damping triangular piece 125 also needs to be hingedly connected with the main body 11.

[0042] The damping telescopic rod 126 can be elongated or shortened. The damping spring 127 is sleeved on the damping telescopic rod 126. The damping spring 127 can be a compression spring or a tension spring. The two ends of the damping spring 127 are respectively connected with the two ends of the damping telescopic rod 126.

[0043] When the walking wheel 120 bounces up and down, the parallel four-bar linkage mechanism 123 deforms, which can push or pull the connecting rod 124 to move. The connecting rod 124 pulls the damping triangular piece 125 to swing relative to the main body 11, thereby pulling the damping telescopic rod 126 to elongate or shorten. The damping spring 127 is stretched or compressed, thereby achieving damping.

[0044] It should be noted that the "damping triangular piece 125" in the present embodiment refers to the fact that the hinging shafts of the damping triangular piece 125, the connecting rod 124 and the damping telescopic rod 126 are distributed in a triangular shape. The damping triangular piece 125 does not necessarily have a triangular structure. The damping triangular piece 125 can also have a rectangular block structure or a disc structure, etc.

[0045] The walking wheel 120 is driven by the walking motor 122. The walking motor 122 can be a direct current motor, an asynchronous motor, a synchronous motor, etc. The walking motor 122 can be driven by a battery on the main body 11.

[0046] The transmission connection mode between the walking wheel 120 and the walking motor 122 is not limited. For example, the walking wheel 120 and the walking motor 122 can be directly transmission connected, i.e., the walking motor 122 is fixedly connected with the mounting frame, and the output shaft of the walking motor 122 is coaxially fixed with the rotating shaft of the walking wheel 120. The walking wheel 120 and the walking motor 122 can also be indirectly transmission connected through other transmission structures. In the present embodiment, the walking motor 122 is arranged on the main body 11, and the walking motor 122 and the walking wheel 120 are transmission connected through the universal joint coupling 128. In this way, the weight at the walking wheel 120 can be reduced, the energy loss is small, and the walking motor 122 is not prone to bouncing, thereby ensuring the working stability.

[0047] Specifically, the universal joint coupling 128 includes two transmission universal joints, which can realize variable-angle power transmission and change the position of the transmission shaft direction. The first end of the universal joint coupling 128 is rotationally supported on the main body 11 and is in transmission connection with the walking motor 122. The second end is fixedly connected with the rotating shaft of the walking wheel 120.

[0048] The connection mode of the first end of the universal joint coupling 128 with the walking motor 122 can be direct transmission connection, or indirect transmission connection through a belt pulley, a gear speed increaser, a gear speed reducer, a gear, a sprocket and chain mechanism.

[0049] The mowing assembly 13 is connected with the main body 11, and the mowing assembly 13 can be lifted. With the lifting of the mowing assembly 13, the intelligent mowing robot 10 can meet the mowing needs of different heights. Of course, the mowing assembly 13 can also not work.

[0050] The number of the mowing assembly 13 is not limited and can be one, two, three, four, etc. In the embodiment, the number of the mowing assembly 13 is two, and the two mowing assemblies 13 are arranged on both sides of the main body 11.

[0051] The structure of the mowing assembly 13 is as follows: please refer to Figure 5 、 Figure 6 The mowing assembly 13 includes a lifting frame 130, a cutter head 131, a mowing motor 132 and a flexible shielding assembly 133.

[0052] The shape and structure of the lifting frame 130 are not limited and can be cylindrical, frame structure, block structure, plate structure, etc. The lifting frame 130 is arranged on the main body 11 in a liftable manner. The connection relationship between the lifting frame 130 and the main body 11 is not limited. They can be directly connected in a sliding fit, or connected through a telescopic cylinder, etc. In the embodiment, two slide ways are arranged on both sides of the main body 11. The number of the slide ways is not limited and can be two, three, etc. A slide block 135 is correspondingly arranged on the lifting frame 130. The slide block 135 and the slide way can be one-to-one corresponding. One slide way can also be matched with two or more slide blocks 135.

[0053] The slide block 135 and the slide way are in sliding fit. Their matching mode can refer to the prior art. For example, the cross section of the slide block 135 and the slide way is T-shaped. The slide block 135 can slide up and down along the slide way, so that the mowing assembly 13 can be lifted relative to the main body 11.

[0054] The mowing motor 132 can be arranged on the lifting frame 130. The type of the mowing motor 132 is not limited and can be a direct current motor, an asynchronous motor, a synchronous motor, etc. The mowing motor 132 can be driven by a battery on the main body 11.

[0055] The cutter head 131 is located at the bottom of the lifting frame 130, and the cutter head 131 is in transmission connection with the output shaft of the mower motor 132. The two can be directly connected or indirectly connected. The cutter head 131 can be driven by the mower motor 132. When the cutter head 131 is driven by the mower motor 132 at high speed, the grass can be cut off. The connection mode of the cutter head 131 and the output shaft of the mower motor 132 is not limited, for example, welding, clamping, connecting through a threaded fastener, etc. Generally, the two can be connected in a detachable manner.

[0056] The style of the cutter head 131 is not limited and can refer to the prior art. For example, the cutter head 131 is provided with blades, saw blades, and grass cutting ropes, etc. Different types of cutter heads 131 can be replaced according to actual needs.

[0057] The bottom of the lifting frame 130 is provided with a shielding disc 134, and the cutter head 131 is located in the shielding disc 134. The connection mode between the lifting frame 130 and the shielding disc 134 is not limited, for example, the two can be integrally formed, welded, connected through a threaded fastener, etc. In this embodiment, the lifting frame 130 and the shielding disc 134 are detachably connected, which is convenient for maintenance and replacement of the cutter head 131 and other structures.

[0058] The style of the shielding disc 134 is not limited and can be a planar plate structure, a block structure, a cylindrical structure, etc. In this embodiment, the shielding disc 134 is in the shape of a stepped shaft.

[0059] There is a gap between the edge of the cutter head 131 and the inner surface of the shielding disc 134. Generally, the bottom end of the shielding disc 134 is lower than the bottom end of the cutter head 131. In this way, when the intelligent grass cutting robot 10 advances, even if it encounters an obstacle, the shielding disc 134 will contact the obstacle first. If the obstacle can enter the inside of the shielding disc 134, it is not easy to contact the obstacle because the cutter head 131 is higher, which can provide the first layer of protection.

[0060] The shielding disc 134 is located around or on one side of the cutter head 131. In this embodiment, the cross section of the shielding disc 134 is in the shape of an arc, that is, the shielding disc 134 only shields half of the cutter head 131 around, and the opening thereof faces the inner side of the main body 11. The two shielding discs 134 are oppositely arranged, and the openings of the two are opposite. Since the two grass cutting assemblies 13 are oppositely arranged, the grass splashed towards the inner side will be blocked by the other grass cutting assembly 13. Therefore, the middle part can not be covered by the shielding disc 134. In this way, the structure is more lightweight and easy to install.

[0061] The flexible shielding assembly 133 is used to form the second layer of protection. Specifically, the flexible shielding assembly 133 includes a plurality of hanging pieces. The number of the hanging pieces can be set according to needs. Generally, the more the number of the hanging pieces, the more secure the protection.

[0062] The hanging parts are hung on the bottom of the shielding disc 134, forming a structure similar to a curtain, and the hanging parts can sway. Of course, the hanging parts need to have a certain strength to block the splashing grass, which is relatively easy to meet. As long as the hanging parts can block the objects with a certain speed, the higher the strength, the better the blocking effect.

[0063] When the intelligent mowing robot 10 is walking, if it encounters an obstacle lower than the shielding disc 134, the hanging parts can sway to enable the mowing assembly 13 to pass smoothly; if the grass inside wants to splash from the bottom of the shielding disc 134, the hanging parts can block it, so that the splashing grass is left in the shielding disc 134, effectively protecting the safety of people around.

[0064] The structure of the hanging parts is not limited, for example, the hanging parts adopt a flexible rod structure or a structure similar to a bell, and in the embodiment, the hanging parts adopt a chain structure, that is, the hanging parts include at least two chain links that are sequentially sleeved, one of the chain links is hung on the bottom of the shielding disc 134, and the chain link is in a long circular or elliptical shape. In this way, the protection area of a single hanging part can be increased, and a better effect can be achieved through a limited number of hanging parts.

[0065] In addition, the mowing assembly 13 can be controlled to rise and fall through the lifting assembly 14, and the lifting assembly 14 is arranged on the main body 11.

[0066] The structure of the lifting assembly 14 is not limited, and in the embodiment, the lifting assembly 14 includes a lifting motor 140, a lifting pulley 141, and a lifting rope 142. The lifting pulley 141 is rotationally arranged on the main body 11, the output shaft of the lifting motor 140 is connected with a winch, and the lifting rope 142 is wound on the lifting pulley 141 and has two ends connected with the winch and the lifting frame 130, respectively. When the lifting motor 140 rotates in the forward direction, the winch can be driven to rotate, so that the lifting rope 142 is wound on the winch, and the mowing assembly 13 is lifted upward. When the lifting motor 140 rotates in the reverse direction, the winch can be driven to rotate, so that the lifting rope 142 is gradually separated from the winch, and the mowing assembly 13 falls under the action of gravity.

[0067] In other embodiments, the lifting assembly 14 can also adopt other structures, for example, the lifting assembly 14 includes a lifting motor 140 and a ball screw mechanism. The ball screw mechanism includes a screw and a nut. The screw is rotationally supported on the main body 11 and is arranged in the vertical direction. The screw is in transmission connection with the lifting motor 140. The nut is in threaded connection with the screw, and the nut is fixedly connected with the lifting frame 130. When the lifting motor 140 drives the screw to rotate around the center line thereof, the mowing assembly 13 can be lifted. Alternatively, the lifting assembly 14 includes a telescopic cylinder. The two ends of the telescopic cylinder are connected with the main body 11 and the lifting frame 130, respectively. The telescopic cylinder extends in the vertical direction. The telescopic cylinder can be elongated or shortened, so as to drive the mowing assembly 13 to rise and fall.

[0068] In addition, the lifting assembly 14 can further include a lifting plate 143 detachably connected with the lifting frame 130, and one end of the lifting rope 142 is fixedly connected with the lifting plate 143. In this way, the lifting assembly 14 and the mowing assembly 13 are more convenient and fast to disassemble and assemble.

[0069] In addition, the intelligent mowing robot 10 can further include a control system for controlling the actions of the walking motor 122, the mowing motor 132, the lifting motor 140 and the like, and the control system can be equipped with a remote controller, so that the user can remotely control the intelligent mowing robot 10 to work. Of course, the intelligent mowing robot 10 can also be provided with a camera, which can automatically identify, autonomously plan a route and autonomously mow grass through the built-in program.

[0070] The working method of the intelligent mowing robot 10 provided by the embodiment is as follows:

[0071] The user starts the intelligent mowing robot 10, which can be started by a key, a remote controller or an APP.

[0072] The walking motor 122 works to drive the walking assembly 12 to move, so that the intelligent mowing robot 10 moves forward.

[0073] After the intelligent mowing robot 10 reaches the specified position, the lifting motor 140 works to make the mowing assembly 13 fall to the specified height.

[0074] The mowing motor 132 works to drive the cutter head 131 to rotate at high speed, and the blades on the cutter head 131 can cut the grass.

[0075] The intelligent mowing robot 10 moves and mows at the same time to complete the mowing work of the lawn.

[0076] During the working process of the intelligent mowing robot 10, if a larger obstacle is encountered, the outer side of the shielding plate 134 will abut against the obstacle, and the obstacle cannot enter the shielding plate 134. At this time, the intelligent mowing robot 10 intelligently detours or the user removes the obstacle. If a smaller obstacle is encountered, the obstacle is lower than the bottom end of the shielding plate 134, and since the suspension piece can sway and deform, the obstacle can smoothly enter the inside. However, the height of the cutter head 131 is higher than the height of the bottom end of the shielding plate 134, and the obstacle will not contact the cutter head 131, so the obstacle will not damage the cutter head 131. The grass cut by the cutter head 131 has a certain initial speed, and when it wants to fly out from the bottom of the shielding plate 134, it will be blocked by the suspension piece, so that it can only be left inside and will not affect the surrounding people.

[0077] The above steps are not absolute sequence, can increase or decrease, modify, adjust sequence and the like according to needs, for example, if the lifting assembly 14 adopts other structure, the corresponding steps can be adjusted.

[0078] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
