Description

Technical Field

[0001] The present application relates to the technical field of lawn mowing machinery, and in particular to a grass clippings collecting device. Background Art

[0002] When the lawn mower is operating outdoors, it is necessary to further use the lawn mower's grass collecting device or manual cleaning to clean the grass clippings in the grass collecting box to prevent accumulation and thus affect the next mowing.

[0003] Existing grass collection devices all tilt the grass collection box in one direction to lift it, allowing grass clippings to fall out of the opening. However, the mower chassis is low, and the grass collection device is also located low. The entire grass collection box needs to be tilted a sufficient angle to effectively unload the grass. As the tilt angle increases, the center of gravity of the entire grass collection box also increases, making the entire mower prone to tipping over. Utility Model Content

[0004] In view of this, the present application provides a grass clippings collection device, so that grass can be unloaded without much change in the center of gravity, thereby reducing the risk of the lawn mower tipping over.

[0005] One embodiment of the present application provides a grass clippings collection device. The grass clippings collection device includes a driving mechanism and a grass clippings collection basket. The grass clippings collection basket includes a connecting member, a mounting member, a first flap and a second flap. The connecting member, the mounting member, the first flap and the second flap together form a grass clippings collection chamber. The connecting member is used to dock with the self-moving device and is provided with a grass clippings inlet. The mounting member is provided on one side of the connecting member. The first flap and the second flap are rotatably provided on opposite sides of the mounting member. The driving mechanism is provided on the mounting member and is transmission-connected to the first flap and / or the second flap to drive the first flap and / or the second flap to expand or fold. The grass clippings outlet of the grass clippings collection basket is formed when the first flap and / or the second flap are expanded or folded. The grass clippings outlet faces the working surface of the self-moving device.

[0006] In the above-mentioned embodiment, the first flap and the second flap of the grass clipping collection basket enclose a grass clipping collection chamber, and the first flap and the second flap are rotatably arranged on both sides of the mounting member. When the grass clipping collection basket needs to be unloaded, the first flap and / or the second flap are driven by the driving mechanism to expand or fold, thereby forming a grass clipping outlet facing the working surface of the self-moving device. During this unloading process, since the grass clipping outlet is formed by the expansion or folding of the first flap and / or the second flap and faces the working surface of the self-moving device, the entire grass clipping collection basket does not need to be tilted a large angle away from the working surface to unload the grass. The center of gravity of the grass clipping collection basket does not change significantly, thereby reducing the risk of the lawn mower tipping over during unloading.

[0007] In some embodiments of the present application, the drive mechanism includes a first motor and a first transmission mechanism. The first motor is disposed inside the mounting member and its motor output shaft is connected to the first transmission mechanism.

[0012] In the above embodiment, a first gear set is used to transmit power generated by the first motor to the first rotating shaft, thereby driving the first rotating shaft to rotate. Two first hinged members are further fixed to each end of the first rotating shaft, and the two first hinged members are connected to the sides of the first flip cover. When the first rotating shaft rotates, the first hinged members rotate with the first rotating shaft, thereby driving the first flip cover to rotate. The use of a gear mechanism to transmit power is compact and space-saving. The forward and reverse rotation of the first gear set can also drive the first flip cover to expand or fold, allowing the grass collection basket to return to its working state after unloading grass through the grass discharge outlet.

[0013] In some embodiments of the present application, the second transmission mechanism includes a second gear set, a second rotating shaft, and two second hinged members. The second motor and the second rotating shaft are respectively in transmission connection with the second gear set. One end of the two second hinged members is respectively fixed to the two ends of the second rotating shaft, and the other ends of the two second hinged members are respectively connected to the two sides of the second flip cover.

[0014] In the above embodiment, the second gear set is used to transmit the power generated by the second motor to the second rotating shaft to drive the second rotating shaft to rotate. The two second hinging members are further fixed at the two ends of the second rotating shaft, and the two second hinging members are connected to the two sides of the second cover; when the second rotating shaft rotates, the second hinging members rotate with the first rotating shaft, thereby driving the second cover to rotate. The gear mechanism is used to transmit power, which is compact in structure, small in space occupation, and can drive the second cover to unfold or fold through the forward and reverse rotation of the second gear set, so that the grass clippings collection basket can be reset to the working state of collecting grass after completing the grass unloading through the grass clippings discharge outlet.

[0015] In some embodiments of the present application, the mounting member includes a main body portion and a first hinging portion. The first hinging portion is arranged on the main body portion, and the two ends of the first hinging portion are respectively provided with a first hinging groove. The first rotating shaft is arranged through the first hinging portion, and the two ends of the first rotating shaft respectively extend into the two first hinging grooves.

[0016] In the above embodiment, the main body portion of the mounting member provides a position for mounting and fixing the driving mechanism and the first transmission mechanism, and the first hinging portion is used for mounting and fixing the first rotating shaft. Further, the first hinging grooves are arranged at the two ends of the first hinging portion on the main body portion, which on the one hand provides a position for accommodating and mounting the two first hinging members, and on the other hand provides a rotating avoidance space for the two first hinging members, so that the first cover can be unfolded to a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0017] In some embodiments of the present application, the mounting member includes a main body portion and a second hinging portion. The second hinging portion is arranged on the main body portion, and the two ends of the second hinging portion are respectively provided with a second hinging groove. The second rotating shaft is arranged through the first hinging portion, and the two ends of the second rotating shaft respectively extend into the two second hinging grooves.

[0018] In the above embodiment, the main body portion of the mounting member provides a position for mounting and fixing the driving mechanism and the second transmission mechanism, and the second hinging portion is used for mounting and fixing the second rotating shaft. Further, the second hinging grooves are arranged at the two ends of the second hinging portion on the main body portion, which on the one hand provides a position for accommodating and mounting the two second hinging members, and on the other hand provides a rotating avoidance space for the two second hinging members, so that the second cover can be unfolded to a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0019] In some embodiments of the present application, the first flip cover includes a first top wall, a first bottom wall and a first peripheral wall. The first bottom wall is configured to be set toward the working surface. The first top wall and the first bottom wall are arranged opposite to each other. The first peripheral wall is connected between the first top wall and the first bottom wall. The second flip cover includes a second top wall, a second bottom wall and a second peripheral wall. The second bottom wall is configured to be set toward the working surface. The second top wall and the second bottom wall are arranged opposite to each other. The second peripheral wall is connected between the second top wall and the second bottom wall. Wherein, the mounting member is arranged between the first top wall and the second top wall and opposite to the first bottom wall and / or the second top wall. The first top wall and / or the second top wall are transmission-connected to the driving mechanism. When the first bottom wall moves away from the second bottom wall and / or the second bottom wall moves away from the first bottom wall, a grass clippings outlet is formed.

[0020] In the above-described embodiment, the mounting member is positioned between the first and second top walls and opposite the first and / or second bottom walls, effectively utilizing the space at the top of the grass collection basket. When the first and / or second top walls are driven to rotate, they also drive the first and / or second bottom walls to move, thereby forming a grass discharge outlet. Furthermore, the first (or second) top wall serves as the pivot point for the entire first (or second) flap to unfold, raising the pivot point height and thereby improving grass unloading efficiency. The grass discharge outlet is formed when the first bottom wall moves away from the second bottom wall and / or the second bottom wall moves away from the first bottom wall. This allows the grass discharge outlet to be located at the bottom of the grass collection basket. This prevents significant shifts in the center of gravity of the entire grass collection basket during grass unloading, resulting in a more efficient grass unloading process.

[0021] In some embodiments of the present application, when the first bottom wall moves away from the second bottom wall, a side of the first bottom wall facing the grass clippings collecting chamber is inclined relative to the working surface.

[0022] In the above embodiment, when the first flip cover is unfolded, the side of the first bottom wall facing the grass collection chamber is inclined relative to the working surface, and the grass in the grass collection chamber can slide out of the grass discharge outlet along the first bottom wall. At this time, the first bottom wall in an inclined state makes the grass unloading effect better.

[0023] In some embodiments of the present application, when the second bottom wall moves away from the first bottom wall, a side of the second bottom wall facing the grass clippings collecting chamber is inclined relative to the working surface.

[0024] In the above embodiment, when the second flip cover is unfolded, the side of the second bottom wall facing the grass collection chamber is inclined relative to the working surface, and the grass in the grass collection chamber can slide out of the grass discharge outlet along the second bottom wall. At this time, the second bottom wall in an inclined state makes the grass unloading effect better.

[0025] In some embodiments of the present application, in the first flip cover and the second flip cover, at least the first bottom wall and the second bottom wall are connected to each other, so that when the first bottom wall and the second bottom wall are relatively far apart, a grass clippings outlet is formed between the first bottom wall and the second bottom wall.

[0026] In the above embodiment, the first bottom wall and the second bottom wall are relatively distanced to form the grass residue discharge outlet, and when the first bottom wall and the second bottom wall are abutted, the grass residue collecting basket is in a state of collecting forage. When the first bottom wall and the second bottom wall are relatively distanced, the grass residue discharge outlet is formed, and interference is avoided when the first cover and / or the second cover rotates.

[0027] In some embodiments of the present application, the first top wall is provided with two first rotating connecting portions on the side facing the mounting member. The transmission mechanism of the driving mechanism includes a first rotating shaft and two first hinging members. One end of each of the two first hinging members is fixed to the two ends of the first rotating shaft, and the other end of each of the two first hinging members is connected to the two first rotating connecting portions.

[0028] In the above embodiment, when the first rotating shaft is driven to rotate, the two first hinging members connected to the two first rotating connecting portions can drive the first cover to unfold.

[0029] In some embodiments of the present application, the second top wall is provided with two second rotating connecting portions on the side facing the mounting member. The transmission mechanism of the driving mechanism includes a second rotating shaft and two second hinging members. One end of each of the two second hinging members is fixed to the two ends of the second rotating shaft, and the other end of each of the two second hinging members is connected to the two second rotating connecting portions.

[0030] In the above embodiment, when the second rotating shaft is driven to rotate, the two second hinging members connected to the two second rotating connecting portions can drive the second cover to unfold.

[0031] In some embodiments of the present application, the mounting member includes a main body portion and a first hinging portion. The first hinging portion is arranged on the main body portion, and the two ends of the first hinging portion are respectively provided with a first hinging groove. The first rotating shaft is arranged in the first hinging portion, and the two ends of the first rotating shaft respectively extend into the two first hinging grooves. The first rotating connecting portion extends into the first hinging groove to be connected to the first hinging member.

[0032] In the above embodiment, the mounting member is arranged in the top space of the first cover, which improves the rotating point of the first top wall. The mounting member serves as the mounting position of the driving mechanism and the transmission mechanism, which effectively improves the space utilization and makes the entire grass residue collecting basket structure more compact.

[0033] In some embodiments of the present application, the mounting member includes a main body portion and a second hinging portion. The second hinging portion is arranged on the main body portion, and the two ends of the second hinging portion are respectively provided with a second hinging groove. The second rotating shaft is arranged in the second hinging portion, and the two ends of the second rotating shaft respectively extend into the two second hinging grooves. The second rotating connecting portion extends into the second hinging groove to be connected to the second hinging member.

[0034] In the above embodiment, the mounting member is arranged at the top space of the second cover, which improves the rotation point of the second top wall, and the mounting member as the mounting position of the driving mechanism and the transmission mechanism also effectively improves the space utilization, so that the whole grass clippings collecting basket structure is more compact.

[0035] In some embodiments of the present application, the part of the first rotation connecting part connected with the first hinge member extends and bends towards the working surface side to form a first arc-shaped structure. The first arc-shaped structure overlaps the first hinge member.

[0036] In the above embodiment, the first rotation connecting part further forms a first arc-shaped structure, and the first arc-shaped structure overlaps the first hinge member. When the first cover is unfolded, the first rotation connecting part does not fall off relative to the mounting member, but is always connected with the first hinge member to adapt to the larger angle swing of the first cover.

[0037] In some embodiments of the present application, the part of the second rotation connecting part connected with the second hinge member extends and bends towards the working surface side to form a second arc-shaped structure. The second arc-shaped structure overlaps the second hinge member.

[0038] In the above embodiment, the second rotation connecting part further forms a second arc-shaped structure, and the second arc-shaped structure overlaps the second hinge member. When the second cover is unfolded, the second rotation connecting part does not fall off relative to the mounting member, but is always connected with the second hinge member to adapt to the larger angle swing of the second cover.

[0039] An embodiment of the present application provides a self-moving device, including a mower and a grass clippings collecting device, and the grass clippings collecting basket is connected to the mower.

[0040] In the above embodiment, the self-moving device includes a mower and a grass clippings collecting device. When the grass clippings collecting device needs to unload grass, the first cover and / or the second cover is unfolded to form a grass clippings discharge port towards the working surface of the self-moving device. Since the formation of the grass clippings discharge port is not the whole grass clippings collecting basket being turned over, the center of gravity of the grass clippings collecting basket changes less during the unloading process, and the grass clippings discharge port is towards the working surface of the self-moving device, which helps to improve the unloading efficiency.

[0051] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0053] Herein, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0054] It should be noted that when an element is considered to be “connected” to another element, it may be directly connected to the other element or there may be an intermediate element. When an element is considered to be “disposed on” another element, it may be directly disposed on the other element or there may be an intermediate element.

[0055] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0056] An embodiment of the present application provides a grass clippings collection device. The grass clippings collection device includes a driving mechanism and a grass clippings collection basket. The grass clippings collection basket includes a connecting member, a mounting member, a first flap and a second flap. The connecting member, the mounting member, the first flap and the second flap together form a grass clippings collection chamber. The connecting member is used to dock with the self-moving device and a grass clippings inlet is provided on the connecting member. The mounting member is provided on one side of the connecting member. The first flap and the second flap are rotatably provided on opposite sides of the mounting member. The driving mechanism is provided on the mounting member and is transmission-connected to the first flap and / or the second flap to drive the first flap and / or the second flap to expand or fold. The grass clippings outlet of the grass clippings collection basket is formed when the first flap and / or the second flap are expanded or folded. The grass clippings outlet faces the working surface of the self-moving device.

[0057] The first flap and the second flap of the grass clippings collection basket enclose a grass clippings collection chamber, and the first flap and the second flap are rotatably arranged on both sides of the mounting member. When the grass clippings collection basket needs to be unloaded, the first flap and / or the second flap are driven by the driving mechanism to expand or fold, thereby forming a grass clippings discharge outlet facing the working surface of the self-moving device. During this grass clippings discharge process, since the grass clippings discharge outlet is formed by the expansion or folding of the first flap and / or the second flap and faces the working surface of the self-moving device, the entire grass clippings collection basket does not need to be flipped a large angle away from the working surface in order to unload the grass. The center of gravity of the grass clippings collection basket does not change significantly, thereby reducing the risk of the lawn mower tipping over when unloading the grass.

[0058] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0059] See Figures 1 to 3One embodiment of the present application provides a grass clippings collection device 100. The grass clippings collection device 100 includes a driving mechanism and a grass clippings collection basket 1. The grass clippings collection basket 1 includes a connecting member 13, a mounting member 14, a first flip cover 11, and a second flip cover 12. The connecting member 13, the mounting member 14, the first flip cover 11, and the second flip cover 12 enclose a grass clippings collection chamber 101. The connecting member 13 is used to dock with a self-moving device and is provided with a grass clippings inlet 102. The mounting member 14 is provided on one side of the connecting member 13. The first flip cover 11 and the second flip cover 12 are rotatably provided on opposite sides of the mounting member 14. The driving mechanism is provided on the mounting member 14 and is transmission-connected to the first flip cover 11 and / or the second flip cover 12 to drive the first flip cover 11 and / or the second flip cover 12 to unfold or fold. The grass clippings outlet 103 of the grass clippings collection basket 1 is formed when the first flip cover 11 and / or the second flip cover 12 is unfolded or folded. The grass cuttings discharge port 103 faces the working surface of the self-moving device (not shown in the figure).

[0060] The first flap 11 and the second flap 12 of the grass collection basket 1 enclose a grass collection chamber 101, and the first flap 11 and the second flap 12 are rotatably arranged on both sides of the mounting member 14. When the grass collection basket 1 needs to be unloaded, the first flap 11 and / or the second flap 12 are driven by the driving mechanism to expand or fold, thereby forming a grass discharge outlet 103 facing the working surface of the self-moving device. During this unloading process, since the grass discharge outlet 103 is formed by the expansion or folding of the first flap 11 and / or the second flap 12 and faces the working surface of the self-moving device, the entire grass collection basket 1 does not need to be flipped a large angle away from the working surface to unload the grass. The center of gravity of the grass collection basket 1 does not change significantly, reducing the risk of the lawn mower tipping over during unloading.

[0061] In some embodiments, when the grass clippings collecting device 100 is unloading grass, the working surface of the self-moving device is the ground.

[0062] In some embodiments, a drive mechanism is disposed on the mounting member 14 and can be in transmission connection with the first flap 11 or the second flap 12, thereby driving the first flap 11 or the second flap 12 to expand or fold, thereby enabling the grass collection basket 1 to be unloaded. The drive mechanism can also be in transmission connection with both the first flap 11 and the second flap 12 simultaneously, so that the first flap 11 and the second flap 12 are simultaneously expanded or folded, forming a larger grass discharge outlet 103 and improving the grass unloading effect.

[0063] It can be understood that the unfolding means that when unloading grass, the entire first flip cover 11 and / or the entire second flip cover 12 are relatively separated, so that the entire grass collection basket 1 is divided into two. Figure 3 .

[0064] The folding structure is designed to be foldable. When unloading grass, the first flap 11 and / or the second flap 12 are folded, and the volume occupied by the first flap 11 and / or the second flap 12 changes, forming a grass discharge outlet 103 between the first flap 11 and the second flap 12. Both structures ensure that the grass discharge outlet 103 is facing the working surface of the self-propelled equipment.

[0065] In some embodiments, see Figure 4 The driving mechanism includes a first motor 21 and a first transmission mechanism 22. The first motor 21 is arranged on the inner side of the mounting member 14 and its motor output shaft is connected to the first transmission mechanism 22. The first transmission mechanism 22 is connected to the first flip cover 11.

[0066] The first motor 21 is arranged on the inner side of the mounting member 14 to prevent the first motor 21 and the first transmission mechanism 22 of the driving mechanism from being exposed and thus affected by the external environment; the first transmission mechanism 22 is connected to the first flip cover 11, and the first motor 21 can drive the first flip cover 11 to unfold or fold, thereby forming a grass clippings discharge outlet 103 for unloading grass.

[0067] In some embodiments, see Figure 4 The driving mechanism includes a second motor 23 and a second transmission mechanism 24. The second motor 23 is arranged on the inner side of the mounting member 14 and its motor output shaft is connected to the second transmission mechanism 24. The second transmission mechanism 24 is connected to the second flip cover 12.

[0068] The first motor 21 is arranged on the inner side of the mounting member 14 to prevent the first motor 21 and the first transmission mechanism 22 of the driving mechanism from being exposed and thus affected by the external environment; the first transmission mechanism 22 is connected to the first flip cover 11, and the first motor 21 can drive the first flip cover 11 to unfold or fold, thereby forming a grass clippings discharge outlet 103 for unloading grass.

[0069] In some embodiments, the inner side of the mounting member 14 refers to the side of the mounting member 14 facing the grass clippings collecting chamber 101. Figure 1 As shown in , the mounting member 14 is a plate-shaped structure, so the inner side of the mounting member 14 is the side thereof facing the grass clippings collecting chamber 101 .

[0070] In some embodiments, the driving mechanism includes a first motor 21, a first transmission mechanism 22, a second motor 23, and a second transmission mechanism 24; thus, the first motor 21 drives the first flip cover 11 to expand or fold through the first transmission mechanism 22, and the second motor 23 drives the second flip cover 12 to expand or fold through the second transmission mechanism 24, so that the first flip cover 11 and the second flip cover 12 can be expanded or folded at the same time; it can be understood that a single motor can also be used to provide power for the expansion or folding of the first flip cover 11 and the second flip cover 12.

[0071] In some embodiments, the first transmission mechanism 22 includes a first gear set 221, a first rotating shaft 222, and two first hinges 223. The first motor 21 and the first rotating shaft 222 are respectively in transmission connection with the first gear set 221. One end of the two first hinges 223 is fixed to the two ends of the first rotating shaft 222, and the other end of the two first hinges 223 is respectively connected to the two sides of the first flip cover 11.

[0072] A first gear set 221 transmits the power generated by the first motor 21 to the first rotating shaft 222, thereby driving the rotation of the first rotating shaft 222. Two first hinges 223 are further secured to each end of the first rotating shaft 222, and the two first hinges 223 are connected to the sides of the first flip cover 11. When the first rotating shaft 222 rotates, the first hinges 223 rotate along with the first rotating shaft 222, thereby driving the rotation of the first flip cover 11. The use of a gear mechanism to transmit power is compact and space-saving. The forward and reverse rotation of the first gear set 221 can also drive the first flip cover 11 to expand or retract, allowing the grass collection basket 1 to return to its working state for collecting grass after unloading grass through the grass discharge outlet 103.

[0073] In some embodiments, the second transmission mechanism 24 includes a second gear set 241, a second rotating shaft 242, and two second hinged members 243. The second motor 23 and the second rotating shaft 242 are respectively in transmission connection with the second gear set 241. One end of the two second hinged members 243 is fixed to the two ends of the second rotating shaft 242, and the other end of the two second hinged members 243 is respectively connected to the two sides of the second flip cover 12.

[0074] A second gear set 241 transmits the power generated by the second motor 23 to the second rotating shaft 242, driving the second rotating shaft 242 to rotate. Two second hinges 243 are further secured to each end of the second rotating shaft 242, which are connected to the sides of the second flip cover 12. When the second rotating shaft 242 rotates, the second hinges 243 rotate along with the first rotating shaft 222, thereby driving the second flip cover 12 to rotate. The use of a gear mechanism to transmit power is compact and space-saving. The forward and reverse rotation of the second gear set 241 can also drive the second flip cover 12 to expand or fold, allowing the grass collection basket 1 to return to its working state for collecting grass after unloading grass through the grass discharge outlet 103.

[0075] In some embodiments, when the drive mechanism includes a motor, the motor's output shaft is connected to a driving gear, which is meshed with two driven wheels: a first driven wheel and a second driven wheel.

The first hinge portion 1421 is disposed on the main body 141, and a first hinge groove 1431 is defined at each end of the first hinge portion 1421. The first rotation axis 222 passes through the first hinge portion 1421, and the ends of the first rotation axis 222 extend into the two first hinge grooves 1431.

[0077] The main body 141 of the mounting member 14 provides a location for installing and fixing the driving mechanism and the first transmission mechanism 22. The first hinge portion 1421 is used for installing and fixing the first rotating shaft 222. Further, first hinge grooves 1431 are provided at both ends of the first hinge portion 1421 on the main body 141. On the one hand, a location is provided for accommodating and installing the two first hinges 223. On the other hand, a rotation avoidance space is provided for the two first hinges 223, so that the first flip cover 11 can be unfolded at a larger angle, the grass unloading effect is better, and the overall structure can also be made more compact.

[0078] In some embodiments, the mounting member 14 includes a main body portion 141 and a second hinge portion 1422, the second hinge portion 1422 is arranged on the main body portion 141, and a second hinge groove 1432 is respectively provided at both ends of the second hinge portion 1422, the second rotating shaft 242 is passed through the first hinge portion 1421 and the two ends of the second rotating shaft 242 extend into the two second hinge grooves 1432 respectively.

[0079] The main body 141 of the mounting member 14 provides a location for installing and fixing the driving mechanism and the second transmission mechanism 24, and the second hinge portion 1422 is used for installing and fixing the second rotating shaft 242. Further, second hinge grooves 1432 are provided at both ends of the second hinge portion 1422 on the main body 141. On the one hand, a location is provided for accommodating and installing the two second hinges 243, and on the other hand, a rotation avoidance space is provided for the two second hinges 243, so that the second flip cover 12 can be unfolded at a larger angle, the grass unloading effect is better, and the overall structure can also be made more compact.

[0080] In some embodiments, see Figures 1 to 3The first cover 11 comprises a first top wall 111, a first bottom wall 112 and a first peripheral wall 113. The first bottom wall 112 is configured to be arranged towards the working surface. The first top wall 111 and the first bottom wall 112 are oppositely arranged. The first peripheral wall 113 is connected between the first top wall 111 and the first bottom wall 112. The second cover 12 comprises a second top wall 121, a second bottom wall 122 and a second peripheral wall 123. The second bottom wall 122 is configured to be arranged towards the working surface. The second top wall 121 and the second bottom wall 122 are oppositely arranged. The second peripheral wall 123 is connected between the second top wall 121 and the second bottom wall 122. The mounting 14 is arranged between the first top wall 111 and the second top wall 121 and opposite to the first bottom wall 112 and / or the second bottom wall 122. The first top wall 111 and / or the second top wall 121 is in driving connection with the driving mechanism. The first bottom wall 112 is moved away from the second bottom wall 122 and / or the second bottom wall 122 is moved away from the first bottom wall 112 to form the grass residue discharge outlet 103.

[0081] The mounting 14 is arranged between the first top wall 111 and the second top wall 121 and opposite to the first bottom wall 112 and / or the second bottom wall 122, which reasonably utilizes the space at the top of the grass residue collecting basket 1. When the first top wall 111 and / or the second top wall 121 is driven to rotate, the first bottom wall 112 and / or the second bottom wall 122 is moved to form the grass residue discharge outlet 103. Meanwhile, the first top wall 111 (the second top wall 121) is used as the height position of the rotation point when the entire first cover 11 (the second cover 12) is unfolded, which improves the height of the rotation point and thus improves the grass unloading efficiency. The first bottom wall 112 is moved away from the second bottom wall 122 and / or the second bottom wall 122 is moved away from the first bottom wall 112 to form the grass residue discharge outlet 103, so that the grass residue discharge outlet 103 is located at the bottom of the grass residue collecting basket 1. Thus, the grass unloading does not cause a large change in the center of gravity of the entire grass residue collecting basket 1, and the grass unloading effect is better.

[0082] In some embodiments, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the first peripheral wall 113 of the first cover 11 comprises a first side plate 1131 and a second side plate 1132, the second peripheral wall 123 of the second cover 12 comprises a third side plate 1231 and a fourth side plate 1232, the connecting member 13 is configured to connect the second side plate 1132 and the fourth side plate 1232, and the connecting member 13 is also a plate structure. The first side plate 1131, the second side plate 1132, the third side plate 1231, the fourth side plate 1232 and the connecting member 13 are collectively formed as the peripheral side wall of the entire grass residue collecting basket 1. Since the connecting member 13 is provided with the grass residue inlet 102 and the structure for connecting with the self-moving device, the connecting member 13 is designed as a side wall of the grass residue collecting basket 1, which facilitates replacement and disassembly.

[0083] In some embodiments, when the first bottom wall 112 moves away from the second bottom wall 122 , the side of the first bottom wall 112 facing the grass clippings collecting chamber 101 is inclined relative to the working surface.

[0084] When the first flip cover 11 is unfolded or folded, the first bottom wall 112 is inclined toward the grass collecting chamber 101 relative to the working surface, so that the grass in the grass collecting chamber 101 can slide out of the grass discharge outlet 103 along the first bottom wall 112. At this time, the inclined first bottom wall 112 makes the grass unloading effect better.

[0085] In some embodiments, when the second bottom wall 122 moves away from the first bottom wall 112 , the side of the second bottom wall 122 facing the grass clippings collecting chamber 101 is inclined relative to the working surface.

[0086] When the second flip cover 12 is unfolded or folded, the second bottom wall 122 is inclined toward the grass collecting chamber 101 relative to the working surface, and the grass in the grass collecting chamber 101 can slide out of the grass discharge outlet 103 along the second bottom wall 122. At this time, the second bottom wall 122 in an inclined state makes the grass unloading effect better.

[0087] In some embodiments, at least the first bottom wall 112 and the second bottom wall 122 of the first flip cover 11 and the second flip cover 12 are connected to each other, so that when the first bottom wall 112 and the second bottom wall 122 are relatively far apart, a grass clipping outlet 103 is formed between the first bottom wall 112 and the second bottom wall 122 .

[0088] The first bottom wall 112 and the second bottom wall 122 are relatively separated to form a grass discharge outlet 103 for unloading grass. When the first bottom wall 112 and the second bottom wall 122 are connected, the grass collection basket 1 is in a grass collecting state. When the first bottom wall 112 and the second bottom wall 122 are relatively separated to form the grass discharge outlet 103, interference is avoided when the first flip cover 11 and / or the second flip cover 12 rotate.

[0089] In some embodiments, two first rotating connection portions 114 are provided on the side of the first top wall 111 facing the mounting member 14. The transmission mechanism of the drive mechanism includes a first rotating shaft 222 and two first hinged members 223. One end of the two first hinged members 223 is fixed to the two ends of the first rotating shaft 222, and the other end of the two first hinged members 223 is connected to the two first rotating connection portions 114.

[0090] When the first rotating shaft 222 is driven to rotate, the two first hinged components 223 connected to the two first rotating connecting portions 114 can drive the first flip cover 11 to unfold or fold.

[0091] In some embodiments, the transmission mechanism of the driving mechanism further includes a first gear set 221 , and the final output gear of the first gear set 221 is in transmission connection with the first rotating shaft 222 .

[0092] In some embodiments, two second rotational connection portions 124 are provided on the side of the second top wall 121 facing the mounting member 14. The transmission mechanism includes a second rotation shaft 242 and two second hinged members 243. One end of the two second hinged members 243 is fixed to the two ends of the second rotation shaft 242, and the other end of the two second hinged members 243 is connected to the two second rotational connection portions 124.

[0093] When the second rotating shaft 242 is driven to rotate, the two second hinged members 243 connected to the two second rotating connecting portions 124 can drive the second flip cover 12 to unfold or fold.

[0094] In some embodiments, the transmission mechanism further includes a second gear set 241 , and the final output gear of the second gear set 241 is in transmission connection with the second rotating shaft 242 .

[0095] In some embodiments, the mounting member 14 includes a main body 141 and a first hinge portion 1421. The first hinge portion 1421 is disposed on the main body 141, and a first hinge slot 1431 is defined at each end of the first hinge portion 1421. The first rotation axis 222 passes through the first hinge portion 1421, and each end of the first rotation axis 222 extends into the first hinge slots 1431. The first rotation connection portion 114 extends into the first hinge slots 1431 to connect with the first hinge member 223.

[0096] The mounting member 14 is arranged in the top space of the first flip cover 11, which improves the rotation point of the first top wall 111. The mounting member 14 serves as the installation position of the driving mechanism and the transmission mechanism, which also effectively improves the space utilization and makes the entire grass clippings collection basket 1 more compact.

[0097] In some embodiments, the mounting member 14 includes a main body 141 and a second hinge portion 1422. The second hinge portion 1422 is disposed on the main body 141, and a second hinge slot 1432 is defined at each end of the second hinge portion 1422. A second rotation axis 242 passes through the second hinge portion 1422, and each end of the second rotation axis 242 extends into the second hinge slots 1432. The second rotation connector 124 extends into the second hinge slots 1432 to connect with the second hinge member 243.

[0098] The mounting member 14 is arranged in the top space of the second flip cover 12, which improves the rotation point of the second top wall 121. The mounting member 14 serves as the installation position of the driving mechanism and the transmission mechanism, which also effectively improves the space utilization and makes the entire grass clippings collection basket 1 more compact.

[0099] In some embodiments, the portion of the first rotating connection portion 114 connected to the first hinge 223 extends toward the working surface and bends to form a first arc-shaped structure 1141 . The first arc-shaped structure 1141 overlaps the first hinge 223 .

[0100] The first rotating connection portion 114 further forms a first arc-shaped structure 1141, and the first arc-shaped structure 1141 overlaps the first hinge 223. When the first flip cover 11 is unfolded, the first rotating connection portion 114 does not fall off relative to the mounting member 14, but remains connected to the first hinge 223, thereby accommodating a wider swing angle of the first flip cover 11.

[0101] In some embodiments, the portion of the second rotating connection portion 124 connected to the second hinge 243 extends toward the working surface and bends to form a second arc-shaped structure 1241 . The second arc-shaped structure 1241 is overlapped on the second hinge 243 .

[0102] The second rotating connection portion 124 further forms a second arc-shaped structure 1241, and the second arc-shaped structure 1241 overlaps the second hinge 243. When the second flip cover 12 is unfolded, the second rotating connection portion 124 does not fall off relative to the mounting member 14, but remains connected to the second hinge 243, allowing the second flip cover 12 to swing at a larger angle.

[0103] An embodiment of the present application provides a self-propelled device (not shown in the figure), including a lawn mower (not shown in the figure) and a grass clippings collecting device 100 , wherein a grass clippings collecting basket 1 is connected to the lawn mower.

[0104] The self-propelled device includes a lawn mower and a grass clipping collection device 100. When grass clipping collection device 100 needs to unload grass, the first flap 11 and / or the second flap 12 are unfolded to form a grass clipping outlet 103 facing the working surface of the self-propelled device. Because the formation of grass clipping outlet 103 does not require the entire grass clipping collection basket 1 to flip, the center of gravity of the grass clipping collection basket 1 changes little during the unloading process. Furthermore, grass clipping outlet 103 faces the working surface of the self-propelled device, which helps improve unloading efficiency.

[0105] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
