For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.
[0047] The technical solution of the present application is further explained below in conjunction with the accompanying drawings and through specific implementation methods.
[0048] like Figure 1 and Figure 2 As shown, this embodiment provides a pruning machine 100. The pruning machine 100 can trim the branches and leaves of shrubs or other plants neatly through the reciprocating working component 200. The pruning machine 100 includes a main body 300 and a motor 210. The motor 210 is configured to drive the working component 200 to move. At least part of the working component 200 is protruding outside the main body 300. A mounting portion 301 is provided at one end of the main body 300, and the mounting portion 301 is used to connect an energy device 302, such as a DC or AC power supply. In this embodiment, the energy device 302 includes a battery pack 303, and the mounting portion 301 is connected to the battery pack 303. The dimension a of a single battery pack 303 in the vertical direction is greater than or equal to 45 mm and less than or equal to 75 mm. After the mounting portion 301 is installed with the battery pack 303, the overall dimension b of the mounting portion 301 and the battery pack 303 in the vertical direction is greater than or equal to 61 mm and less than or equal to 85 mm. The battery pack 303 is installed on the mounting portion 301 substantially parallel to the extension direction of the pruning machine 100, so that the battery pack 303 occupies little space in the vertical direction. In some embodiments, the direction in which the battery pack 303 is installed on the mounting portion 301 can be horizontal, oblique, vertical, etc., which is not limited here.
[0049] like Figures 1 to 3As shown, the main body 300 includes a first grip portion 310. The first grip portion 310 is for the user to hold. In this embodiment, the length of the bladed portion of the working component 200 in the front-to-back direction is greater than or equal to 200 mm, and the main body 300 includes a first grip portion 310 and a second grip portion 320. The main body 300 has two parts for the user to hold, and the user can selectively use two hands to hold the first grip portion 310 and the second grip portion 320 respectively, or use two hands to hold the first grip portion 310 or the second grip portion 320 together. In some embodiments, the length of the bladed portion of the working component 200 in the front-to-back direction is less than 200 mm, and the main body 300 includes a first grip portion 310 or a second grip portion 320. The main body 300 has a total of one part for the user to hold, and the user can hold the first grip portion 310 or the second grip portion 320 with two hands together, or hold the first grip portion 310 or the second grip portion 320 with one hand.
[0050] The main body 300 further includes a receiving portion 330, which receives at least part of the motor 210. The pruning machine 100 further includes a transmission assembly 220 connecting the motor 210 and 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 parts such as planetary gears or spur gears. The receiving portion 330 includes a motor receiving portion 211 and a transmission assembly receiving portion 221. The motor 210 is received in the motor receiving portion 211, and the transmission assembly 220 is received in the transmission assembly receiving portion 221. The transmission assembly receiving portion 221 is located in front of the motor receiving portion 211. In this embodiment, the motor receiving portion 211 and the transmission assembly receiving portion 221 have different shapes and sizes. The size of the transmission assembly receiving portion 221 in the up-down direction is slightly smaller than the size of the motor receiving portion 211 in the up-down direction. In this way, the transmission assembly 220 with a smaller size is received in the transmission assembly receiving portion 221 with a smaller size. The receiving portion 330 has a compact structure, high space utilization, and the pruning machine 100 is light in weight. In some embodiments, the shape and size of the motor housing portion 211 and the transmission assembly housing portion 221 are the same, or the size of the motor housing portion 211 is smaller than the size of the transmission assembly housing portion 221. The housing portion 330 is located between the first grip portion 310 and the second grip portion 320, so that when the user holds the first grip portion 310 and the second grip portion 320 with both hands, a portion of space can be naturally left between the two hands, which is ergonomic.
[0051] The maximum dimension d of the first grip 310, the second grip 320, and the accommodating portion 330 in the vertical direction is less than or equal to 83 mm. In this way, the main body 300 is compact in size in the vertical direction, and when the user rotates the pruning machine 100 along an axis extending in the front-to-back direction, the moment of inertia is small. The maximum dimension e of the first grip 310 and the second grip 320 in the vertical direction is greater than or equal to 38 mm and less than or equal to 50 mm. In this way, the user can hold it comfortably, and the moment of inertia of the part of the main body 300 for the user to hold is small. In some embodiments, the maximum dimension d of the first grip 310, the second grip 320, and the accommodating portion 330 in the vertical direction is less than or equal to 76 mm. In some embodiments, the maximum dimension d of the first grip 310 and the accommodating portion 330 in the vertical direction is less than or equal to 68 mm.
[0052] The pruning machine 100 includes a shield 230, which is arranged on the main body 300. The shield 230 is installed at the intersection of the main body 300 and the working component 200 and is larger than the main body 300 in the vertical direction, so that the user's hands can be protected from being cut by the working component 200. The dimension f of the pruning machine 100 in the vertical direction is greater than or equal to 75 mm and less than or equal to 105 mm. The maximum dimension of the pruning machine 100 in the vertical direction appears at the position where the shield 230 is installed on the main body 300. The shield 230 is light in weight and small in size, and does not have much impact on the rotational inertia of the pruning machine 100.
[0053] In this embodiment, the dimension g of the pruning machine 100 in the front-to-back direction is greater than or equal to 800 mm and less than or equal to 1500 mm. The dimension c of the working assembly 200 in the front-to-back direction is greater than or equal to 390 mm and less than or equal to 610 mm. The dimension h of the main body 300 in the front-to-back direction is greater than or equal to 648 mm and less than or equal to 792 mm. In some embodiments, the dimension g of the pruning machine 100 in the front-to-back direction is greater than or equal to 1050 mm and less than or equal to 1450 mm. The dimension c of the working assembly 200 in the front-to-back direction is greater than or equal to 440 mm and less than or equal to 560 mm. The dimension h of the main body 300 in the front-to-back direction is greater than or equal to 698 mm and less than or equal to 742 mm. Part of the working assembly 200 is arranged in the main body 300, so the working assembly 200 and the main body 300 overlap to a certain extent in the front-to-back direction, but the body length of the pruning machine 100 is basically equivalent to the sum of the lengths of the working assembly 200 and the main body 300.
[0054] When the pruning machine 100 is placed on a plane, the distance i from the uppermost end of the first gripping portion 310 to the plane is less than or equal to 67 mm. The distance j from the uppermost end of the main body 300 to the plane is less than or equal to 86 mm. In this way, the pruning machine 100 has a compact structure and saves space during packaging and transportation.
[0055] The main body 300 includes a housing 304, and a receiving space is formed inside the housing 304. In this embodiment, the housing 304 is an integrally formed component. The first grip portion 310, the second grip portion 320 and the receiving portion 330 are interconnected. In some embodiments, the housing 304 can be formed separately, and the first grip portion 310, the second grip portion 320 and the receiving portion 330 are not all interconnected.
[0056] The main body 300 is provided with a switch 305 for controlling the movement of the motor 210. The user controls the start and stop of the pruning machine 100 through the switch 305. The switch 305 has a release state for stopping the movement of the motor 210 and a press state for starting the movement of the motor 210. When the user safely presses the switch 305, the motor 210 rotates, thereby driving the working component 200 to move. When the user releases the switch 305, the motor 210 stops rotating, thereby stopping the movement of the working component 200. In this embodiment, the motor 210 can be an inner rotor or outer rotor brushless or brushed motor.
[0057] The working assembly 200 includes a first working piece 201 and a second working piece 202. The first working piece 201 and the second working piece 202 are two toothed blades extending substantially in parallel. A surface located at the center of the first working piece 201 and the second working piece 202 and substantially parallel to the extension direction of the first working piece 201 and the second working piece 202 is defined as a center surface 102. In the released state, at least part of the switch 305 is arranged below the center surface 102. The switch 305 includes a pressing surface 306. The pressing surface 306 is an inclined surface, which is convenient for the user to place a finger on the pressing surface and press the switch 305 with less effort. The pressing surface 306 is arranged below the center surface 102. The pressing surface 306 is arranged below the center surface 102, so that when the user presses the switch 305 to operate the pruning machine 100, the user's finger operating the switch 305 is located below the center surface 102. In this embodiment, the second grip portion 320 is arranged behind the first grip portion 310, and at least part of the switch 305 is arranged on the second grip portion 320. There is one switch 305, and the switch 305 is a trigger. The switch 305 is arranged to rotate around the switch axis 307, and the switch 305 axis 307 is arranged above the center plane 102. The switch 305 crosses the center plane 102 in the vertical direction, so that when the user holds the pruning machine 100, the hand crosses the center plane 102 in the vertical direction, that is, the position of the hand in the vertical direction is basically the same as the position of the blade in the vertical direction. The switch 305 has a lowermost end, and the 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 part of the switch 305 is arranged on the first grip portion 310. There may also be multiple switches 305. The switch 305 may be a mechanical switch, an electromagnetic switch, a membrane switch, etc., which is not limited here.
[0058] The battery pack 303 has a lowermost end. After the battery pack 303 is installed on the mounting portion 301, the distance l from the lowermost 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 lowermost end. The lowermost end of the accommodating portion 330 and the lowermost end of the battery pack 303 are flush in the vertical direction. In this way, the pruning machine 100 can be stably placed on a plane with the support of the accommodating portion 330 and the battery pack 303. In addition, when the pruning machine 100 is placed on a plane, since the lowermost ends of the first grip portion 310 and the second grip portion 320 are higher than the lowermost end of the accommodating portion 330, the user can easily pass his hand through the first grip portion 310 and the second grip portion 320 and the plane to pick up the pruning machine 100. In some embodiments, the lowermost end of the accommodating portion 330 and the lowermost end of the mounting portion 301 are flush 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 plane.
[0059] 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 small. In the present 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 substantially 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, the motor 210, and the center plane 102 of the blade is small. In some embodiments, the motor 210 can be arranged vertically, and the rotation axis of the motor 210 extends substantially perpendicular to the extension direction of the working component 200.
[0060] 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.
[0061] The distance o between the center line 104 of the second grip 320 in the vertical direction and the center of gravity x of the motor 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 lines of the second grip 320 and the motor 210 in the vertical direction is small. In this embodiment, the center line 104 of the second grip 320 in the vertical direction intersects with the center of gravity x of the motor, and the distance o between the center line 104 of the second grip 320 in the vertical direction and the center of gravity x of the motor in the vertical direction is 0 mm.
[0062] The distance q between the center of gravity p of the transmission assembly 220 and the center of gravity x of the motor 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 p of the transmission assembly 220 and the center of gravity x of the motor in the vertical direction is small.
[0063] The distance s between the center of gravity r of the battery pack 303 and the center of gravity x of the motor 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 battery pack 303 and the center of gravity x of the motor in the vertical direction is small. The distance between the center lines of the motor 210, the transmission assembly 220, the first grip 310, the second grip 320, the battery pack 303 and the motor housing 211 in the vertical direction is small. Regardless of the specific axis used by the user to rotate the pruning machine 100, when the user rotates the pruning machine 100 around an axis extending in the front-to-back direction, the moment of inertia is small, and the pruning machine 100 is comfortable and safe to use.
[0064] The weight of the pruning machine 100 is greater than or equal to 2kg and less than or equal to 3kg. The weight of the battery pack 303 is greater than or equal to 420g and less than or equal to 514g. The pruning machine 100 includes a control device, which is accommodated in the accommodating portion 330. The weight of the control device is less than or equal to 125g. The control device includes a PCB board. The overall weight of the working assembly 200, the transmission assembly 220 and the motor 210 is greater than or equal to 1.2kg and less than or equal to 1.5kg. The weight of the working assembly 200 is greater than or equal to 850g and less than or equal to 1050g. The weight of the motor 210 is greater than or equal to 120g and less than or equal to 155g. The weight of the transmission assembly 220 is greater than or equal to 240g and less than or equal to 300g. Figures 1 to 5 As shown, 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 the user rotates the pruning machine 100 around an axis extending in the front-to-back direction, the weight of each part is relatively evenly and closely distributed around the rotation axis, the moment of inertia is small, and the position change of the center of gravity of the pruning machine 100 in the up-down direction is small, and the user will not sprain his wrist due to the sudden change of the center of gravity of the pruning machine 100. The size, weight distribution and handle setting of the pruning machine 100 are reasonable, and the pruning machine 100 is 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. In this way, when the user holds the first grip portion 310, the weight of the pruning machine 100 in front of the user's hand and behind the user's hand is basically balanced, and the pruning machine 100 is comfortable to use during rotation and normal use.
