Description

Pruning machine

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 26, 2023 with application number 202310927779.0 and the Chinese patent application filed with the China Patent Office on April 22, 2024 with application number 202410491333.2, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of garden tools, and in particular to a pruning machine. Background Art

[0003] A pruning machine in the related art is usually used to prune branches and leaves. Existing pruning machines used to prune branches of shrubs or other plants are large in size and weight in order to be able to effectively prune branches or leaves. Under some working conditions, the user needs to turn the pruning machine to change the cutting direction of the pruning machine, so that the user can shape the branches or shrubs. For such heavy handheld garden tools, the size of the tool, the distribution of the tool weight and the setting of the handle become the key to the user's comfortable and safe operating experience. The pruning machines currently on the market often have a large moment of inertia when the user turns the pruning machine due to unreasonable tool size, weight distribution or handle setting, making the operation uncomfortable and unsafe. This section provides background information related to this application, which is not necessarily prior art.

[0046] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0047] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0048] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0049] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0050] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0051] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts.

In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0053] As shown in Figures 1 and 2, this embodiment provides a pruning machine 100. The pruning machine 100 is capable of neatly trimming the branches and leaves of shrubs or other plants using a reciprocating working assembly 200. The pruning machine 100 includes a main body 300 and a motor 210. The motor 210 is configured to drive the working assembly 200. At least a portion of the working assembly 200 protrudes from the main body 300. A mounting portion 301 is provided at one end of the main body 300. The mounting portion 301 is configured to connect to an energy device 302, such as a DC or AC power source. In this embodiment, the energy device 302 includes a battery pack 303, which is connected to the mounting portion 301. The vertical dimension a of a single battery pack 303 is greater than or equal to 45 mm and less than or equal to 75 mm. When the battery pack 303 is mounted on the mounting portion 301, the overall vertical dimension b of the mounting portion 301 and the battery pack 303 is greater than or equal to 61 mm and less than or equal to 85 mm. The battery pack 303 is mounted to the mounting portion 301 substantially parallel to the extension direction of the pruning machine 100. In this way, the battery pack 303 occupies less space in the vertical direction. In some embodiments, the direction in which the battery pack 303 is mounted to the mounting portion 301 can be horizontal, oblique, vertical, etc., which is not limited here.

[0054] As shown in Figures 1 to 3, the main body 300 includes a first grip portion 310. The first grip portion 310 is for the user to grasp. In this embodiment, the bladed portion of the working assembly 200 is greater than or equal to 200 mm in the front-to-back direction, and the main body 300 includes the first grip portion 310 and the second grip portion 320. The main body 300 has two portions for the user to grasp. The user can selectively grasp the first grip portion 310 and the second grip portion 320 with both hands, or grasp the first grip portion 310 or the second grip portion 320 with both hands. In some embodiments, the bladed portion of the working assembly 200 is less than 200 mm in the front-to-back direction, and the main body 300 includes the first grip portion 310 or the second grip portion 320. The main body 300 has a single portion for the user to grasp. The user can grasp the first grip portion 310 or the second grip portion 320 with both hands, or grasp the first grip portion 310 or the second grip portion 320 with one hand.

[0055] The main body 300 also includes a housing 330 that accommodates at least a portion of the motor 210. The pruning machine 100 also includes a transmission assembly 220 that connects the motor 210 to the working assembly 200. In this embodiment, the transmission assembly 220 includes a bevel gear. In some embodiments, the transmission assembly 220 also includes common transmission components such as planetary gears or spur gears. The housing 330 includes a motor housing 211 and a transmission assembly housing 221. The motor 210 is housed in the motor housing 211, and the transmission assembly 220 is housed in the transmission assembly housing 221. The transmission assembly housing 221 is located in front of the motor housing 211. In this embodiment, the motor housing 211 and the transmission assembly housing 221 have different shapes and sizes. The vertical dimension of the transmission assembly housing 221 is slightly smaller than that of the motor housing 211. This allows the smaller transmission assembly 220 to be accommodated in the smaller transmission assembly housing 221. This results in a compact housing 330, high space utilization, and a lightweight pruning machine 100. In some embodiments, the motor housing 211 and the transmission assembly housing 221 have the same shape and size, or the motor housing 211 is smaller than the transmission assembly housing 221. The housing portion 330 is located between the first grip 310 and the second grip 320. This allows a user to hold the first grip 310 and the second grip 320 with one hand, leaving a natural space between the two hands, which is ergonomic.

[0056] The maximum vertical dimension d of the first grip 310, the second grip 320, and the accommodating portion 330 is less than or equal to 83 mm. This makes the main body 300 compact in the vertical direction, and when a user rotates the pruning machine 100 about an axis extending in the front-to-back direction, the moment of inertia is low. The maximum vertical dimension e of the first grip 310 and the second grip 320 is greater than or equal to 38 mm and less than or equal to 50 mm. This provides a comfortable grip for the user, and the portion of the main body 300 that the user grips has a low moment of inertia. In some embodiments, the maximum vertical dimension d of the first grip 310, the second grip 320, and the accommodating portion 330 is less than or equal to 76 mm. In some embodiments, the maximum vertical dimension d of the first grip 310 and the accommodating portion 330 is less than or equal to 68 mm.

[0057] The pruning machine 100 includes a guard 230 mounted on the main body 300. The guard 230 is mounted at the intersection of the main body 300 and the working assembly 200 and is larger in the vertical direction than the main body 300. This protects the user's hands from being cut by the working assembly 200. The vertical dimension f of the pruning machine 100 is greater than or equal to 75 mm and less than or equal to 105 mm. The maximum vertical dimension of the pruning machine 100 occurs where the guard 230 is mounted on the main body 300. The guard 230 is lightweight and compact, and does not significantly affect the rotational inertia of the pruning machine 100.

[0058] In this embodiment, the front-to-back dimension g of the pruning machine 100 is greater than or equal to 800 mm and less than or equal to 1500 mm. The front-to-back dimension c of the working assembly 200 is greater than or equal to 390 mm and less than or equal to 610 mm. The front-to-back dimension h of the main body 300 is greater than or equal to 648 mm and less than or equal to 792 mm. In some embodiments, the front-to-back dimension g of the pruning machine 100 is greater than or equal to 1050 mm and less than or equal to 1450 mm. The front-to-back dimension c of the working assembly 200 is greater than or equal to 440 mm and less than or equal to 560 mm. The front-to-back dimension h of the main body 300 is greater than or equal to 698 mm and less than or equal to 742 mm. Part of the working assembly 200 is located within the main body 300, so there is some overlap between the working assembly 200 and the main body 300 in the front-to-back direction. However, the length of the pruning machine 100 is substantially equal to the sum of the lengths of the working assembly 200 and the main body 300.

[0059] When the pruning machine 100 is placed on a flat surface, the distance i between the top end of the first grip 310 and the flat surface is less than or equal to 67 mm. The distance j between the top end of the main body 300 and the flat surface is less than or equal to 86 mm. This makes the pruning machine 100 compact and space-saving during packaging and transportation.

[0060] The main body 300 includes a housing 304, which has a storage space formed inside. In this embodiment, the housing 304 is an integrally formed component. The first grip portion 310, the second grip portion 320, and the storage portion 330 are interconnected. In some embodiments, the housing 304 may be formed separately, and the first grip portion 310, the second grip portion 320, and the storage portion 330 may not all be interconnected.

[0061] The main body 300 is equipped with a switch 305 that controls the movement of the motor 210. The main body 300 includes the switch 305. The user controls the start and stop of the pruning machine 100 via the switch 305. The switch 305 has a release state, which stops the motor 210, and a press state, which starts the motor 210. When the user safely presses the switch 305, the motor 210 rotates, thereby driving the working assembly 200. When the user releases the switch 305, the motor 210 stops rotating, and the working assembly 200 stops moving. In this embodiment, the motor 210 can be an inner rotor or outer rotor brushless or brushed motor.

[0062] The working assembly 200 includes a first working member 201 and a second working member 202. The first working member 201 and the second working member 202 are two toothed blades extending substantially parallel to each other. A plane located at the center of the first and second working members 201, 202 and substantially parallel to the direction in which they extend is defined as the center plane 102. In the released state, at least a portion of the switch 305 is positioned below the center plane 102. The switch 305 includes a pressing surface 306. The pressing surface 306 is an inclined surface that facilitates the user placing their finger on the pressing surface and pressing the switch 305 with less effort. The pressing surface 306 is positioned below the center plane 102. This positioning of the pressing surface 306 ensures that when the user presses the switch 305 to operate the pruning machine 100, the user's finger is positioned below the center plane 102. In this embodiment, the second grip portion 320 is positioned behind the first grip portion 310, and at least a portion of the switch 305 is positioned on the second grip portion 320. There is one switch 305, which serves as a trigger. The switch 305 is configured to rotate about a switch axis 307, which is positioned above the center plane 102. The switch 305 vertically spans the center plane 102. This allows the user's hand to vertically span the center plane 102 when holding the pruning machine 100, meaning that the vertical position of the hand is substantially the same as that of the blade. The switch 305 has a lowermost end, and a distance k from the lowermost end of the switch 305 to the center plane 102 is greater than or equal to 14 mm and less than or equal to 50 mm. In some embodiments, at least a portion of the switch 305 is positioned on the first grip portion 310. Multiple switches 305 are also possible. The switch 305 can be a mechanical switch, an electromagnetic switch, a membrane switch, or the like, without limitation.

[0063] The battery pack 303 has a bottom end. After the battery pack 303 is installed in the mounting portion 301, the distance l from the bottom end of the battery pack 303 to the center plane 102 is greater than or equal to 14 mm and less than or equal to 50 mm. The accommodating portion 330 has a bottom end. The bottom end of the accommodating portion 330 is flush with the bottom end of the battery pack 303 in the vertical direction. In this way, the pruning machine 100 can be placed stably on a flat surface, supported by the accommodating portion 330 and the battery pack 303. Furthermore, when the pruning machine 100 is placed on a flat surface, because the bottom ends of the first grip 310 and the second grip 320 are higher than the bottom end of the accommodating portion 330, the user can easily pass their hand between the first grip 310 and the second grip 320 and the flat surface to pick up the pruning machine 100. In some embodiments, the bottom end of the accommodating portion 330 is flush with the bottom end of the mounting portion 301 in the vertical direction. In this way, when the battery pack 303 is not installed, the pruning machine 100 can also be placed stably on a flat surface.

[0064] The motor 210 has a motor center of gravity x, and the distance m between the center plane 102 and the motor center of gravity x in the vertical direction is greater than or equal to 0 mm and less than or equal to 40 mm. The distance between the center of gravity of the motor 210 and the working component 200 in the vertical direction is relatively small. In this embodiment, the motor 210 has a rotation axis, which is the center line of the motor 210. The motor 210 is arranged horizontally, and the rotation axis of the motor 210 extends basically along the extension direction of the working component 200. The motor accommodating portion 211 has a first center line 101, and the motor center of gravity x is located on the first center line 101. The distance between the rotation axis of the working component 210 and the center plane 102 of the blade is relatively small. In some embodiments, the motor 210 can be arranged vertically, and the rotation axis of the motor 210 extends basically perpendicular to the extension direction of the working component 200.

[0065] The vertical distance n between the center line 103 of the first grip 310 and the motor gravity center x is greater than or equal to 0 mm and less than or equal to 40 mm. The vertical distance between the first grip 310 and the center line of the motor 210 is small.

[0066] The vertical distance o between the centerline 104 of the second grip 320 and the motor's center of gravity x is greater than or equal to 0 mm and less than or equal to 40 mm. The vertical distance between the second grip 320 and the motor 210 is relatively small. In this embodiment, the vertical centerline 104 of the second grip 320 intersects the motor's center of gravity x, and the vertical distance o between the centerline 104 of the second grip 320 and the motor's center of gravity x is 0 mm.

[0067] The vertical distance q between the center of gravity p of the transmission assembly 220 and the center of gravity x of the motor is greater than or equal to 0 mm and less than or equal to 40 mm. The vertical distance q between the center of gravity p of the transmission assembly 220 and the center of gravity x of the motor is small.

[0068] The vertical distance s between the center of gravity r of the battery pack 303 and the center of gravity x of the motor is greater than or equal to 0 mm and less than or equal to 40 mm. The vertical distance between the center of gravity r of the battery pack 303 and the center of gravity x of the motor is relatively small. The vertical center lines of the motor 210, transmission assembly 220, first grip 310, second grip 320, battery pack 303, and motor housing 211 are relatively small. Regardless of the specific axis used by the user to rotate the pruning machine 100, when the user rotates the pruning machine 100 about an axis extending in the front-to-back direction, the moment of inertia is small, making the pruning machine 100 comfortable and safe to use.

[0069] The weight of the pruning machine 100 is greater than or equal to 2 kg and less than or equal to 3 kg. The weight of the battery pack 303 is greater than or equal to 420 g and less than or equal to 514 g. The pruning machine 100 includes a control device, which is housed in the housing 330. The weight of the control device is less than or equal to 125 g. The control device includes a printed circuit board (PCB). The combined weight of the working assembly 200, the transmission assembly 220, and the motor 210 is greater than or equal to 1.2 kg and less than or equal to 1.5 kg. The weight of the working assembly 200 is greater than or equal to 850 g and less than or equal to 1050 g. The weight of the motor 210 is greater than or equal to 120 g and less than or equal to 155 g. The weight of the transmission assembly 220 is greater than or equal to 240 g and less than or equal to 300 g. As shown in Figures 1 to 5, the projections of the working assembly 200, the transmission assembly 220, the motor 210, the switch 305, and the battery pack 303 in the front-to-back direction at least partially overlap. When a user rotates the pruning machine 100 about an axis extending in the front-to-back direction, the weight of the various components is relatively evenly and tightly distributed around the axis of rotation, resulting in a small moment of inertia. The vertical position of the pruning machine 100's center of gravity changes little, and the user will not suffer a wrist sprain due to a sudden shift in the pruning machine's center of gravity. The pruning machine 100 has a reasonable size, weight distribution, and handle configuration, making it comfortable and safe to use. In some embodiments, the center of gravity of the pruning machine 100 is located on the first grip portion 310. This ensures that when a user grips the first grip portion 310, the weight of the pruning machine 100 is essentially balanced between the front and back of the user's hand, making the pruning machine 100 comfortable to use both during rotation and in normal use.
