Description

Grass clipping collection device

[0001] This application claims priority to Chinese Patent Application No. 202422683148.1, filed on November 1, 2024, entitled "Grass Clipping Collection Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of lawn mowing machinery technology, and more specifically, to a grass clipping collection device. Background Technology

[0003] When a lawnmower is operating outdoors, it is necessary to clean the grass clippings in the grass collection box using the lawnmower's grass collection device or manually to prevent them from accumulating and affecting the next mowing session.

[0004] Existing grass collection devices all involve flipping the grass collection box in one direction to lift it up, allowing grass clippings to fall from the opening. However, lawnmowers have low chassis, and the grass collection device is also positioned low. The entire grass collection box needs to be flipped at a sufficient angle to achieve effective grass unloading. As the flipping angle increases, the center of gravity of the entire grass collection box also becomes relatively higher, making the entire lawnmower prone to tipping backward. Summary of the Invention

[0005] In view of this, this application provides a grass clipping collection device to enable unloading of grass with minimal change in the center of gravity, thereby reducing the risk of the lawnmower tipping over.

[0006] One embodiment of this application provides a grass clipping collection device. The grass clipping collection device includes a drive mechanism and a grass clipping collection basket. The grass clipping collection basket includes a connector, a mounting member, a first flip cover, and a second flip cover. The connector, mounting member, first flip cover, and second flip cover together form a grass clipping collection cavity. The connector is used to dock with a self-moving device and has a grass clipping inlet. The mounting member is located on one side of the connector. The first flip cover and second flip cover are rotatably disposed on opposite sides of the mounting member. The drive mechanism is disposed on the mounting member and is drively connected to the first flip cover and / or the second flip cover to drive the first flip cover and / or the second flip cover to unfold or fold. The grass clipping outlet of the grass clipping collection basket is formed when the first flip cover and / or the second flip cover is unfolded or folded. The grass clipping outlet faces the working surface of the self-moving device.

[0007] In the above embodiment, the first and second flaps of the grass clipping collection basket enclose a grass clipping collection cavity, and the first and second flaps are rotatably mounted on both sides of the mounting component. When the grass clipping collection basket needs to be unloaded, the first and / or second flaps are opened or folded by a drive mechanism, 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 opening or folding of the first and / or second flaps and faces the working surface of the self-moving device, it is not necessary for the entire grass clipping collection basket to be rotated at a large angle away from the working surface to unload the grass. The change in the center of gravity of the grass clipping collection basket is not significant, reducing the risk of the lawnmower tipping over during unloading.

[0008] In some embodiments of this application, the drive mechanism includes a first motor and a first transmission mechanism. The first motor is located inside the mounting component, and its motor output shaft is connected to the first transmission mechanism. The first transmission mechanism is connected to the first flip cover.

[0009] In the above embodiments, the first motor is located inside the mounting component to prevent the first motor and the first transmission mechanism of the drive mechanism from being exposed and thus affected by the external environment; the first transmission mechanism is connected to the first flip cover, and the first motor can drive the first flip cover to open or fold, thereby forming a straw discharge outlet for unloading straw.

[0010] In some embodiments of this application, the drive mechanism includes a second motor and a second transmission mechanism. The second motor is located inside the mounting component, and its motor output shaft is connected to the second transmission mechanism. The second transmission mechanism is connected to the second flip cover.

[0011] In the above embodiments, the first motor is located inside the mounting component to prevent the first motor and the first transmission mechanism of the drive mechanism from being exposed and thus affected by the external environment; the first transmission mechanism is connected to the first flip cover, and the first motor can drive the first flip cover to open or fold, thereby forming a straw discharge outlet for unloading straw.

[0012] In some embodiments of this application, the first transmission mechanism includes a first gear set, a first rotating shaft, and two first hinge members. A first motor and the first rotating shaft are respectively connected to the first gear set for transmission. One end of each of the two first hinge members is fixed to both ends of the first rotating shaft, and the other ends of each of the two first hinge members are respectively connected to both sides of the first flip cover.

[0013] In the above embodiment, a first gear set is used to transmit the power generated by the first motor to the first rotating shaft, thereby driving the first rotating shaft to rotate. Two first hinge members are further fixed to both ends of the first rotating shaft, and these two first hinge members are connected to both sides of the first flip cover. When the first rotating shaft rotates, the first hinge members rotate with the first rotating shaft, thereby driving the first flip cover to rotate. Using a gear mechanism to transmit power results in a compact structure, small footprint, and the forward and reverse rotation of the first gear set can drive the first flip cover to open or fold, allowing the grass clipping collection basket to return to its working state of collecting grass after unloading grass through the grass clipping outlet.

[0014] In some embodiments of this application, the second transmission mechanism includes a second gear set, a second rotating shaft, and two second hinge members. The second motor and the second rotating shaft are respectively connected to the second gear set for transmission. One end of each of the two second hinge members is fixed to both ends of the second rotating shaft, and the other ends of each of the two second hinge members are respectively connected to both sides of the second flip cover.

[0015] In the above embodiment, a second gear set is used to transmit the power generated by the second motor to the second rotating shaft, thereby driving the second rotating shaft to rotate. Two second hinges are further fixed to both ends of the second rotating shaft, and the two second hinges are connected to the two sides of the second flip cover. When the second rotating shaft rotates, the second hinges rotate along with the first rotating shaft, thereby driving the second flip cover to rotate. Using a gear mechanism to transmit power results in a compact structure, small footprint, and the forward and reverse rotation of the second gear set can drive the second flip cover to open or fold, allowing the grass clipping collection basket to return to its working state of collecting grass after unloading through the grass clipping outlet.

[0016] In some embodiments of this application, the mounting component includes a main body and a first hinge portion. The first hinge portion is disposed on the main body, and each end of the first hinge portion is provided with a first hinge groove. A first rotating shaft passes through the first hinge portion, and both ends of the first rotating shaft extend into the two first hinge grooves respectively.

[0017] In the above embodiments, the main body of the mounting component provides a position for mounting and fixing the drive mechanism and the first transmission mechanism. The first hinge part is used for mounting and fixing the first rotating shaft. Furthermore, the first hinge groove is provided at both ends of the first hinge part on the main body. On the one hand, it provides a position for accommodating and installing the two first hinge parts. On the other hand, it provides a space for the two first hinge parts to rotate, so that the first flap can open at a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0018] In some embodiments of this application, the mounting component includes a main body and a second hinge portion. The second hinge portion is disposed on the main body and has a second hinge groove at each end. The second rotating shaft passes through the first hinge portion and extends into the two second hinge grooves at both ends.

[0019] In the above embodiments, the main body of the mounting component provides a position for mounting and fixing the drive mechanism and the second transmission mechanism. The second hinge part is used for mounting and fixing the second rotating shaft. Furthermore, second hinge grooves are provided at both ends of the second hinge part on the main body. On the one hand, it provides a position for accommodating and installing the two second hinge parts. On the other hand, it provides a space for the two second hinge parts to rotate, so that the second flap can open at a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0020] In some embodiments of this application, the first flap includes a first top wall, a first bottom wall, and a first peripheral wall. The first bottom wall is configured to face the working surface. The first top wall and the first bottom wall are disposed opposite to each other. The first peripheral wall is connected between the first top wall and the first bottom wall. The second flap includes a second top wall, a second bottom wall, and a second peripheral wall. The second bottom wall is configured to face the working surface. The second top wall and the second bottom wall are disposed opposite to each other. The second peripheral wall is connected between the second top wall and the second bottom wall. A mounting member is disposed between the first top wall and the second top wall and is opposite to the first bottom wall and / or the second bottom wall. The first top wall and / or the second top wall are drive-connected to a drive 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 clipping outlet is formed.

[0021] In the above embodiment, the mounting component is positioned between the first and second top walls and opposite to the first and / or second bottom walls, making reasonable use of the space at the top of the grass clipping collection basket. When the first and / or second top walls are driven to rotate, they also move the first and / or second bottom walls, thus forming a grass clipping outlet. Simultaneously, the first (second) top wall is positioned at the height of the rotation point of the entire first (second) flap opening, increasing the rotation point height and thus improving unloading efficiency. 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 clipping outlet is formed, placing it at the bottom of the grass clipping collection basket. This prevents a significant shift in the center of gravity of the entire grass clipping collection basket during unloading, resulting in better unloading performance.

[0022] In some embodiments of this application, when the first bottom wall moves away from the second bottom wall, the side of the first bottom wall facing the grass clipping collection chamber is inclined relative to the working surface.

[0023] In the above embodiment, when the first flap is opened, the side of the first bottom wall facing the grass clipping collection chamber is inclined relative to the working surface, and the grass clippings in the grass clipping collection chamber can slide out of the grass clipping outlet along the first bottom wall. At this time, the inclined first bottom wall makes the grass unloading effect better.

[0024] In some embodiments of this application, when the second bottom wall moves away from the first bottom wall, the side of the second bottom wall facing the grass clipping collection chamber is inclined relative to the working surface.

[0025] In the above embodiment, when the second flap is unfolded, the side of the second bottom wall facing the grass clipping collection chamber is inclined relative to the working surface, and the grass clippings in the grass clipping collection chamber can slide out of the grass clipping outlet along the second bottom wall. At this time, the inclined second bottom wall makes the grass unloading effect better.

[0026] In some embodiments of this application, in the first flap and the second flap, at least the first bottom wall and the second bottom wall are in contact with each other, so that when the first bottom wall and the second bottom wall are relatively far apart, a grass clipping outlet is formed between the first bottom wall and the second bottom wall.

[0027] In the above embodiment, the first bottom wall and the second bottom wall are relatively far apart to form a grass clipping outlet for unloading grass. When the first bottom wall and the second bottom wall are connected, the grass clipping collection basket is in the state of collecting grass. Furthermore, the grass clipping outlet is formed when the first bottom wall and the second bottom wall are relatively far apart, thus avoiding interference when the first flap and / or the second flap rotate.

[0028] In some embodiments of this application, the first top wall has two first rotating connecting portions on the side facing the mounting member. The transmission mechanism of the drive mechanism includes a first rotating shaft and two first hinge members. One end of each of the two first hinge members is fixed to both ends of the first rotating shaft, and the other end of each of the two first hinge members is connected to the two first rotating connecting portions.

[0029] In the above embodiment, when the first rotating shaft is driven to rotate, the two first hinge members connected to the two first rotating connecting parts can drive the first flip cover to unfold.

[0030] In some embodiments of this application, the second top wall has two second rotating connecting portions on the side facing the mounting member. The transmission mechanism of the drive mechanism includes a second rotating shaft and two second hinge members. One end of each of the two second hinge members is fixed to both ends of the second rotating shaft, and the other end of each of the two second hinge members is connected to the two second rotating connecting portions.

[0031] In the above embodiment, when the second rotating shaft is driven to rotate, the two second hinge members connected to the two second rotating connecting parts can drive the second flip cover to unfold.

[0032] In some embodiments of this application, the mounting component includes a main body and a first hinge portion. The first hinge portion is disposed on the main body, and each end of the first hinge portion is provided with a first hinge groove. A first rotating shaft passes through the first hinge portion, and both ends of the first rotating shaft extend into the two first hinge grooves respectively. A first rotating connection portion extends into the first hinge groove to connect with a first hinge member.

[0033] In the above embodiments, the mounting component is located in the top space of the first flip cover, which increases the rotation point of the first top wall. As the mounting position of the drive mechanism and transmission mechanism, the mounting component also effectively improves the space utilization rate, making the entire grass clipping collection basket structure more compact.

[0034] In some embodiments of this application, the mounting member includes a main body and a second hinge portion. The second hinge portion is disposed on the main body, and each end of the second hinge portion is provided with a second hinge groove. A second rotating shaft passes through the second hinge portion, and both ends of the second rotating shaft extend into the two second hinge grooves respectively. A second rotating connection portion extends into the second hinge grooves to connect with a second hinge member.

[0035] In the above embodiments, the mounting component is located in the top space of the second flip cover, which increases the rotation point of the second top wall. As the mounting position of the drive mechanism and transmission mechanism, the mounting component also effectively improves the space utilization rate, making the entire grass clipping collection basket structure more compact.

[0036] In some embodiments of this application, the portion of the first rotating connection that connects to the first hinge extends toward the working surface and bends to form a first arc-shaped structure. The first arc-shaped structure overlaps the first hinge.

[0037] In the above embodiment, the first rotating connecting portion further forms a first arc-shaped structure, and the first arc-shaped structure overlaps the first hinge member. When the first flip cover is unfolded, the first rotating connecting portion will not detach from the mounting member, but will always be connected to the first hinge member to accommodate the larger angle of the first flip cover's swing.

[0038] In some embodiments of this application, the portion of the second rotating connection that connects to the second hinge extends toward the working surface and bends to form a second arc-shaped structure. The second arc-shaped structure overlaps the second hinge.

[0039] In the above embodiment, the second rotating connecting portion further forms a second arc-shaped structure, and the second arc-shaped structure overlaps the second hinge member. When the second flip cover is opened, the second rotating connecting portion will not detach from the mounting member, but will always be connected to the second hinge member to accommodate the larger angle of the second flip cover's swing.

[0040] One embodiment of this application provides a self-moving device, including a lawnmower and a grass clipping collection device, wherein the grass clipping collection basket is connected to the lawnmower.

[0041] In the above embodiments, the self-moving device includes a lawnmower and a grass clipping collection device. When the grass clipping collection device needs to unload grass, a grass clipping outlet is formed facing the working surface of the self-moving device by unfolding a first flap and / or a second flap. Since the formation of the grass clipping outlet does not involve the entire grass clipping collection basket flipping over, the center of gravity of the grass clipping collection basket changes little during the unloading process, and the grass clipping outlet facing the working surface of the self-moving device helps to improve unloading efficiency.

[0051] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0053] The terms “first,” “second,” “third,” and “fourth” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "located" on another component, it can be directly located on the other component or there may be an intervening component present.

[0055] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0056] This application provides a grass clipping collection device. The grass clipping collection device includes a drive mechanism and a grass clipping collection basket. The grass clipping collection basket includes a connector, a mounting member, a first flip cover, and a second flip cover. The connector, mounting member, first flip cover, and second flip cover together form a grass clipping collection cavity. The connector is used to dock with a self-moving device and has a grass clipping inlet. The mounting member is located on one side of the connector. The first flip cover and second flip cover are rotatably disposed on opposite sides of the mounting member. The drive mechanism is disposed on the mounting member and is drively connected to the first flip cover and / or the second flip cover to drive the first flip cover and / or the second flip cover to unfold or fold. The grass clipping outlet of the grass clipping collection basket is formed when the first flip cover and / or the second flip cover is unfolded or folded. The grass clipping outlet faces the working surface of the self-moving device.

[0057] The first and second flaps of the grass clipping collection basket enclose a grass clipping collection cavity, and are rotatably mounted on both sides of the mounting component. When the grass clipping collection basket needs to be unloaded, a drive mechanism drives the first and / or second flaps to unfold 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 unfolding or folding the first and / or second flaps and facing the working surface of the self-moving device, it is not necessary for the entire grass clipping collection basket to be rotated at a large angle away from the working surface to unload the grass. The change in the center of gravity of the grass clipping collection basket is not significant, reducing the risk of the lawnmower tipping over during unloading.

[0058] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0059] Please refer to Figures 1 to 3. One embodiment of this application provides a grass clipping collection device 100. The grass clipping collection device 100 includes a drive mechanism and a grass clipping collection basket 1. The grass clipping collection basket 1 includes a connector 13, a mounting member 14, a first flip cover 11, and a second flip cover 12. The connector 13, mounting member 14, first flip cover 11, and second flip cover 12 enclose a grass clipping collection cavity 101. The connector 13 is used to dock with a self-moving device and has a grass clipping inlet 102. The mounting member 14 is located on one side of the connector 13. The first flip cover 11 and the second flip cover 12 are rotatably disposed on opposite sides of the mounting member 14. The drive mechanism is disposed on the mounting member 14 and is drively 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 clipping outlet 103 of the grass clipping collection basket 1 is formed when the first flip cover 11 and / or the second flip cover 12 is unfolded or folded. The grass clipping outlet 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 clipping collection basket 1 enclose a grass clipping collection cavity 101, and the first flap 11 and the second flap 12 are rotatably mounted on both sides of the mounting member 14. When the grass clipping collection basket 1 needs to unload grass, the first flap 11 and / or the second flap 12 are driven to unfold or fold by the drive mechanism, thereby forming a grass clipping outlet 103 facing the working surface of the self-moving device. In this unloading process, since the grass clipping outlet 103 is formed by unfolding or folding the first flap 11 and / or the second flap 12 and facing the working surface of the self-moving device, it is not necessary for the entire grass clipping collection basket 1 to be flipped at a large angle away from the working surface to unload grass. The change in the center of gravity of the grass clipping collection basket 1 is not large, reducing the risk of the lawnmower tipping over during unloading.

[0061] In some embodiments, when the grass clipping collection device 100 unloads grass, the working surface of the self-moving device is the ground.

[0062] In some embodiments, the drive mechanism is mounted on the mounting member 14 and can be driven to the first flip cover 11 or the second flip cover 12, thereby driving the first flip cover 11 or the second flip cover 12 to unfold or fold, so as to unload the grass clipping collection basket 1. The drive mechanism can also be driven to the first flip cover 11 and the second flip cover 12 simultaneously, so that the first flip cover 11 and the second flip cover 12 unfold or fold synchronously to form a larger grass clipping outlet 103 and improve the grass unloading effect.

[0063] It can be understood here that "unfolding" refers to the state in which the entire first flap 11 and / or the entire second flap 12 are relatively far apart when unloading the hay, so that the entire hay clipping collection basket 1 is divided into two parts, as shown in Figure 3.

[0064] The folding design involves the first flap 11 and / or the second flap 12 being designed to be foldable. When unloading hay, the first flap 11 and / or the second flap 12 folds, changing their volume and creating a hay discharge outlet 103 between them. Both of these structures ensure that the hay discharge outlet 103 faces the working surface of the self-moving equipment.

[0065] In some embodiments, as shown in FIG4, the drive mechanism includes a first motor 21 and a first transmission mechanism 22. The first motor 21 is located inside 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 placed inside the mounting part 14 to prevent the first motor 21 and the first transmission mechanism 22 of the drive 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 open or fold, thereby forming the grass clipping outlet 103 for unloading grass.

[0067] In some embodiments, referring to FIG4, the drive mechanism includes a second motor 23 and a second transmission mechanism 24. The second motor 23 is located inside 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 placed inside the mounting part 14 to prevent the first motor 21 and the first transmission mechanism 22 of the drive 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 open or fold, thereby forming the grass clipping 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 clipping collection chamber 101. As shown in FIG1, the mounting member 14 is a plate-shaped structure, so the inner side of the mounting member 14 is the side facing the grass clipping collection chamber 101.

[0070] In some embodiments, the drive 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 unfold or fold through the first transmission mechanism 22, and the second motor 23 drives the second flip cover 12 to unfold or fold through the second transmission mechanism 24, so that the first flip cover 11 and the second flip cover 12 can be unfolded or folded simultaneously; it is understood that a single motor can also be used to provide power for the unfolding 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 hinge members 223. The first motor 21 and the first rotating shaft 222 are respectively connected to the first gear set 221 for transmission. One end of each of the two first hinge members 223 is fixed to both ends of the first rotating shaft 222, and the other end of each of the two first hinge members 223 is respectively connected to both 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, driving the first rotating shaft 222 to rotate. Two first hinge members 223 are further fixed to both ends of the first rotating shaft 222, and these two first hinge members 223 are connected to both sides of the first flip cover 11. When the first rotating shaft 222 rotates, the first hinge members 223 rotate along with the first rotating shaft 222, thereby driving the first flip cover 11 to rotate. Using a gear mechanism to transmit power results in a compact structure, small footprint, and the forward and reverse rotation of the first gear set 221 can also drive the first flip cover 11 to open or close, allowing the grass clipping collection basket 1 to return to its working state of collecting grass after unloading grass through the grass clipping 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 hinge members 243. The second motor 23 and the second rotating shaft 242 are respectively connected to the second gear set 241 for transmission. One end of each of the two second hinge members 243 is fixed to both ends of the second rotating shaft 242, and the other end of each of the two second hinge members 243 is respectively connected to both sides of the second flip cover 12.

[0074] The 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 hinge members 243 are further fixed to both ends of the second rotating shaft 242, and the two second hinge members 243 are connected to the two sides of the second flip cover 12. When the second rotating shaft 242 rotates, the second hinge members 243 rotate along with the first rotating shaft 222, thereby driving the second flip cover 12 to rotate. Using a gear mechanism to transmit power results in a compact structure, small footprint, and the forward and reverse rotation of the second gear set 241 can also drive the second flip cover 12 to open or fold, allowing the grass clipping collection basket 1 to return to its working state of collecting grass after unloading grass through the grass clipping outlet 103.

[0075] In some embodiments, when the drive mechanism includes a motor, the output shaft of the motor is driven by a driving gear that meshes with two driven wheels simultaneously, namely a first driven wheel and a second driven wheel. The first driven wheel is driven by a first rotating shaft 222, and the second driven wheel is driven by a second rotating shaft 242. An intermediate gear is then placed between the first driven wheel and the driving gear as an idler gear, or the idler gear is placed between the second driven wheel and the driving gear. In this way, a single motor can drive the first flip cover 11 and the second flip cover 12 to rotate or fold simultaneously.

[0076] Referring to Figure 5, 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 each end of the first hinge portion 1421 is provided with a first hinge groove 1431. A first rotating shaft 222 passes through the first hinge portion 1421, and both ends of the first rotating shaft 222 extend into the two first hinge grooves 1431.

[0077] The main body 141 of the mounting component 14 provides a position for mounting and fixing the drive mechanism and the first transmission mechanism 22. The first hinge part 1421 is used for mounting and fixing the first rotating shaft 222. Furthermore, the main body 141 provides a first hinge groove 1431 at both ends of the first hinge part 1421. On the one hand, it provides a position for accommodating and installing the two first hinge parts 223. On the other hand, it provides a space for the two first hinge parts 223 to rotate, so that the first flap 11 can open at a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0078] 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 groove 1432 is provided at both ends of the second hinge portion 1422. The second rotating shaft 242 passes through the first hinge portion 1421, and both ends of the second rotating shaft 242 extend into the two second hinge grooves 1432.

[0079] The main body 141 of the mounting component 14 provides a position for mounting and fixing the drive mechanism and the second transmission mechanism 24. The second hinge part 1422 is used for mounting and fixing the second rotating shaft 242. Furthermore, the second hinge groove 1432 is provided at both ends of the second hinge part 1422 on the main body 141. On the one hand, it provides a position for accommodating and installing the two second hinge parts 243. On the other hand, it provides a space for the two second hinge parts 243 to rotate, so that the second flap 12 can open at a larger angle, the grass unloading effect is better, and the overall structure is more compact.

[0080] In some embodiments, referring to Figures 1 to 3, the first flip cover 11 includes a first top wall 111, a first bottom wall 112, and a first peripheral wall 113. The first bottom wall 112 is configured to face the working surface. The first top wall 111 and the first bottom wall 112 are disposed opposite to each other. The first peripheral wall 113 is connected between the first top wall 111 and the first bottom wall 112. The second flip cover 12 includes a second top wall 121, a second bottom wall 122, and a second peripheral wall 123. The second bottom wall 122 is configured to face the working surface. The second top wall 121 and the second bottom wall 122 are disposed opposite to each other. The second peripheral wall 123 is connected between the second top wall 121 and the second bottom wall 122. A mounting member 14 is disposed 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 are drive-connected to a drive mechanism. When the first bottom wall 112 moves away from the second bottom wall 122 and / or the second bottom wall 122 moves away from the first bottom wall 112, a grass clipping outlet 103 is formed.

[0081] The mounting component 14 is positioned 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. This makes efficient use of the space at the top of the grass clipping collection basket 1. When the first top wall 111 and / or the second top wall 121 are driven to rotate, the first bottom wall 112 and / or the second bottom wall 122 can also be moved, thus forming the grass clipping outlet 103. Simultaneously, the first top wall 111 (second top wall 121) is positioned at the height of the rotation point when the entire first flap 11 (second flap 12) is unfolded, increasing the rotation point height and thus improving the grass unloading efficiency. When the first bottom wall 112 moves away from the second bottom wall 122 and / or the second bottom wall 122 moves away from the first bottom wall 112, the grass clipping outlet 103 is formed, placing it at the bottom of the grass clipping collection basket 1. This prevents a significant shift in the center of gravity of the entire grass clipping collection basket 1 during unloading, resulting in better unloading performance.

[0082] In some embodiments, as shown in Figures 1, 2, 6, and 7, the first peripheral wall 113 of the first flip cover 11 includes a first side plate 1131 and a second side plate 1132, and the second peripheral wall 123 of the second flip cover 12 includes a third side plate 1231 and a fourth side plate 1232. A connector 13 is configured to connect the second side plate 1132 and the fourth side plate 1232, and the connector 13 is also a plate-like structure. The first side plate 1131, the second side plate 1132, the third side plate 1231, the fourth side plate 1232, and the connector 13 together form the peripheral side wall of the entire grass clipping collection basket 1. Since the connector 13 is provided with a grass clipping inlet 102 and a structure for connecting to the self-moving device, the connector 13 is designed as a side wall of the grass clipping collection basket 1 for easy 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 clipping collection chamber 101 is inclined relative to the working surface.

[0084] When the first flap 11 is unfolded or folded, the side of the first bottom wall 112 facing the grass clipping collection chamber 101 is inclined relative to the working surface, and the grass clippings in the grass clipping collection chamber 101 can slide out of the grass clipping discharge outlet 103 along the first bottom wall 112. At this time, the first bottom wall 112 in an inclined state 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 clipping collection chamber 101 is inclined relative to the working surface.

[0086] When the second flap 12 is unfolded or folded, the side of the second bottom wall 122 facing the grass clipping collection chamber 101 is inclined relative to the working surface, and the grass clippings in the grass clipping collection chamber 101 can slide out of the grass clipping discharge outlet 103 along the second bottom wall 122. At this time, the inclined second bottom wall 122 makes the grass unloading effect better.

[0087] In some embodiments, in the first flap 11 and the second flap 12, at least the first bottom wall 112 and the second bottom wall 122 are in contact with each other, such 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 far apart to form a grass clipping outlet 103 for unloading grass. When the first bottom wall 112 and the second bottom wall 122 are connected, the grass clipping collection basket 1 is in the state of collecting grass. And when the first bottom wall 112 and the second bottom wall 122 are relatively far apart, the grass clipping outlet 103 is formed to avoid interference when the first flap 11 and / or the second flap 12 rotate.

[0089] In some embodiments, the first top wall 111 is provided with two first rotating connection portions 114 on the side facing the mounting member 14. The transmission mechanism of the drive mechanism includes a first rotating shaft 222 and two first hinge members 223. One end of each of the two first hinge members 223 is fixed to both ends of the first rotating shaft 222, and the other end of each of the two first hinge 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 hinges 223 connected to the two first rotating connecting parts 114 can drive the first flip cover 11 to unfold or fold.

[0091] In some embodiments, the transmission mechanism of the drive mechanism further includes a first gear set 221, the final output gear of the first gear set 221 being connected to the first rotating shaft 222 in a transmission connection.

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

[0093] When the second rotating shaft 242 is driven to rotate, the two second hinge members 243 connected to the two second rotating connecting parts 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, the final output gear of the second gear set 241 being drive-connected to 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 each end of the first hinge portion 1421 is provided with a first hinge groove 1431. A first rotating shaft 222 passes through the first hinge portion 1421, and both ends of the first rotating shaft 222 extend into the two first hinge grooves 1431. A first rotating connection portion 114 extends into the first hinge grooves 1431 to connect with the first hinge member 223.

[0096] Mounting component 14 is positioned in the top space of the first flip cover 11, which increases the rotation point of the first top wall 111. As the mounting position for the drive mechanism and transmission mechanism, mounting component 14 also effectively improves space utilization, making the entire grass clipping collection basket 1 structure more compact.

[0097] 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 disposed on the main body portion 141, and each end of the second hinge portion 1422 is provided with a second hinge groove 1432. A second rotating shaft 242 passes through the second hinge portion 1422, and both ends of the second rotating shaft 242 extend into the two second hinge grooves 1432. A second rotating connection portion 124 extends into the second hinge grooves 1432 to connect with the second hinge member 243.

[0098] Mounting component 14 is positioned in the top space of the second flip cover 12, which increases the rotation point of the second top wall 121. As the mounting position for the drive mechanism and transmission mechanism, mounting component 14 also effectively improves space utilization, making the entire grass clipping collection basket 1 structure more compact.

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

[0100] The first rotating connecting part 114 further forms a first arc-shaped structure 1141, and the first arc-shaped structure 1141 overlaps the first hinge member 223. When the first flip cover 11 is unfolded, the first rotating connecting part 114 will not fall off relative to the mounting member 14, but will always be connected to the first hinge member 223 to accommodate the larger angle of the first flip cover 11.

[0101] In some embodiments, the portion of the second rotating connection 124 that connects to the second hinge 243 extends toward the working surface and bends to form a second arcuate structure 1241. The second arcuate structure 1241 overlaps the second hinge 243.

[0102] The second rotating connecting part 124 further forms a second arc-shaped structure 1241, and the second arc-shaped structure 1241 overlaps the second hinge member 243. When the second flip cover 12 is unfolded, the second rotating connecting part 124 will not fall off relative to the mounting member 14, but will always be connected to the second hinge member 243 to accommodate the larger angle of the swing of the second flip cover 12.

[0103] One embodiment of this application provides a self-moving device (not shown in the figure), including a lawnmower (not shown in the figure) and a grass clipping collection device 100, with a grass clipping collection basket 1 connected to the lawnmower.

[0104] The self-moving device includes a lawnmower and a grass clipping collection device 100. When the grass clipping collection device 100 needs to unload grass, the first flap 11 and / or the second flap 12 unfold to form a grass clipping outlet 103 facing the working surface of the self-moving device. Since the formation of the grass clipping outlet 103 does not involve the entire grass clipping collection basket 1 flipping over, the center of gravity of the grass clipping collection basket 1 changes little during the unloading process. Furthermore, the grass clipping outlet 103 faces the working surface of the self-moving device, which helps to improve unloading efficiency.

[0105] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
