[0042] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.
[0043] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0044] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.
[0045] In this application, the terms "connection," "combination," "coupling," and "installation" can 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 the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.
[0046] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values of the two endpoints. Relative terms may refer to 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. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.
[0047] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.
[0048] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.
[0049] Currently, some pruning machines require the machine to be placed on a flat surface when installing or removing the battery pack, and the user then installs or removes the battery pack from the side of the machine. The battery pack has a certain weight, making side installation or removal inconvenient and resulting in a poor user experience. Therefore, this application proposes a pruning machine that improves the convenience of battery pack installation and removal without changing the position of the battery pack connection point.
[0050] refer to Figure 1 The pruning machine provided in this embodiment is a unidirectional pruning machine, and the user typically walks in one direction to use the pruning machine. In some embodiments, the pruning machine may also be a bidirectional pruning machine. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, left, right, front, and back sides are shown.
[0051] like Figures 1 to 3 As shown, the pruning machine includes a housing assembly 100, a cutting assembly 200, a motor 300, and a battery pack 400. The housing assembly 100 constitutes the main body of the pruning machine, and its interior can form a receiving space. Other components, which will be described later, can be connected to the housing assembly 100, supported by the housing assembly 100, and housed or partially housed within the receiving space of the housing assembly 100. The housing assembly 100 can be separate, for example, formed by the joining of left and right housings, or it can be integral. The housing assembly 100 generally also has a grip or handle for the user to hold.
[0052] The cutting assembly 200 is the working part of the pruning machine that performs cutting operations. The cutting assembly includes a first blade 210, a second blade 220, and a blade support 230. The first blade 210 and the second blade 220 are connected above the blade support 230, and are positioned on the left and right sides of the pruning machine, respectively. The first blade 210 and the second blade 220 are mounted on the blade support 230. The first blade 210 and the second blade 220 extend along a first direction 101, and the second blade 220 reciprocates relative to the first blade 210 along the first direction 101. Figure 1 As shown, the first blade 210 and the second blade 220 are currently aligned on both sides, and the first direction 101 is the front-to-back direction of the pruning machine. The first blade 210 includes a first cutting edge 211, and the second blade includes a second cutting edge 221. Both the first cutting edge 211 and the second cutting edge 221 extend along the second direction 102. The second direction 102 is the vertical direction of the pruning machine, and the second direction 102 is perpendicular to the first direction 101.
[0053] Motor 300 is the prime mover of the pruning machine and can be housed within the housing assembly 100. When the shaft of motor 300 rotates, it can directly or indirectly drive the cutting assembly 200 to operate. Figure 1 Taking the pruning machine shown as an example, there is also a transmission component between the motor 300 and the cutting assembly 200. This transmission component may contain an eccentric mechanism, which can convert the rotational motion of the motor 300 shaft into the reciprocating motion of the first blade 210 and the second blade 220. Through the power transmission of the motor 300 and the transmission component, the first blade 210 and the second blade 220 move relative to each other to perform cutting. In some embodiments, the motor 300 is a DC motor.
[0054] The battery pack 400 is detachably coupled to the housing assembly 100, and the housing assembly 100 has a battery pack coupling portion 110 for coupling with the battery pack 400. The battery pack 400 can supply power to at least the motor 300, and can also supply power to other components or related circuits. Specifically, a drive circuit is provided between the battery pack 400 and the motor 300, and the power supplied by the battery pack 400 can be transferred to the motor 300 by the drive circuit through a DC bus. The battery pack 400 has a capacity of 56V or greater, and is a relatively large capacity battery pack. Optionally, the capacity of the battery pack 400 can be 60V. Optionally, the capacity of the battery pack 400 can be 65V. Optionally, the capacity of the battery pack 400 can be 72V.
[0055] The pruning machine also includes a handle assembly 500 for users to hold and use or carry the pruning machine. The handle assembly 500 includes a first handle 510 and a second handle 520. The first handle 510 is located in the middle of the pruning machine, and the second handle 520 is located at the rear of the pruning machine. A first grip portion 511 is formed on the first handle 510, and a second grip portion 521 is formed on the second handle 520. The first grip portion 511 and the second grip portion 521 extend substantially along a second direction 102, so that the user can hold the first grip portion 511 and the second grip portion 521 with their left and right hands respectively to use or carry the pruning machine. The handle assembly 500 also includes a connector 530 for connecting the second handle 520 to the pruning machine. That is, the first handle 510 is directly connected to the housing assembly 100 of the pruning machine, and the second handle 520 is connected to the housing assembly 100 of the pruning machine via the connector 530. Specifically, the first handle 510 is connected to the front cover 120 in the pruning machine housing assembly 100, and the second handle 520 is connected to the gearbox 130 in the pruning machine housing assembly 100 based on the connector 530.
[0056] like Figures 4 to 7As shown, the pruning machine has two working states: upright and sideways. The working plane includes a plane parallel to the horizontal plane and a plane at a certain angle to the horizontal plane. This application uses a working plane parallel to the horizontal plane as an example for specific explanation. Figure 4 and Figure 6 As shown, when the pruning machine is in the upright position, at least a portion of the housing assembly 100 is in contact with the working surface. At this time, the battery pack 400 is attached to the battery pack joint 110 on the housing assembly 100 from the side of the pruning machine in a direction substantially parallel to the working surface. Figure 8 and Figure 9 As shown, when the pruning machine is in a side-mounted position, it is supported to stand on the working plane. At this time, the angle M between the second direction 102 and the working plane (i.e., the horizontal plane) is greater than or equal to 45 degrees and less than or equal to 90 degrees. The battery pack 400 is attached to the battery pack connection portion 110 on the housing assembly 100 substantially along the second direction 102. Specifically, when the angle between the second direction 102 and the working plane is 90 degrees, the first cutting blade 211 and the second cutting blade 221 extend upwards substantially along a direction perpendicular to the working plane, and the battery pack 400 is attached to the battery pack connection portion 110 substantially along a direction perpendicular to the working plane. When the angle between the second direction 102 and the working plane is less than 90 degrees, the first cutting blade 211 and the second cutting blade 221 extend to the upper left or upper right along a direction with a certain angle to the working plane, and the battery pack 400 is attached to the battery pack connection portion 110 along a direction with a certain angle to the working plane. Optionally, the angle M between the second direction 102 and the working plane (i.e., the horizontal plane) can be 50 degrees. Optionally, the angle M between the second direction 102 and the working plane (i.e., the horizontal plane) can be 60 degrees. Optionally, the angle M between the second direction 102 and the working plane (i.e., the horizontal plane) can be 75 degrees.
[0057] like Figure 3 As shown, in the first direction 101, the first handle 510 and the second handle 520 are located on both sides of the battery pack 400, that is, the first handle 510 is located on the front side of the battery pack 400 and the second handle 520 is located on the rear side of the battery pack 400. This makes the center of gravity of the battery pack 400 located between the two handles after the battery pack 400 is connected to the battery pack connection part 110. This makes it more stable and less strenuous for the user to use or carry the pruning machine by holding the first handle 510 and the second handle 520 with their left and right hands respectively.
[0058] like Figure 5As shown, the battery pack coupling 110 has an opening 111 facing the environment, which can receive at least a portion of the battery pack 400 in the second direction 102. The battery pack 400 is coupled to the battery pack coupling 110 based on the opening 111, and the battery pack 400 has a portion that is exposed and protrudes from the battery pack coupling 110. Specifically, the opening 111 is formed jointly by the battery pack coupling 110 and the second handle 520, and the opening 111 faces upward. Figure 7 As shown, the uppermost part of the battery pack 400 protrudes beyond the battery pack joint 110, and both the left and right sides of the battery pack 400 protrude beyond the battery pack joint 110. Figure 5 As shown, the battery pack coupling portion 110 includes a length X1 along the second direction 102 and a length X2 along the first direction 101. The lengths X1 and X2 are not equal, specifically, the length X1 is greater than the length X2. That is, the battery pack 400 is coupled to the battery pack coupling portion 110 with its longer side along the second direction 102, thereby making it more stable and effortless for the user to use or carry the pruning machine by holding the first handle 510 and the second handle 520 with their left and right hands respectively.
[0059] When the pruning machine is in a side-mounted position, it is supported to stand upright on the working plane. Specifically, the pruning machine includes at least three support points, and the lines connecting any two of these three support points intersect each other, meaning the lines connecting the three support points form a triangle. Furthermore, the pruning machine may have four, five, six, or more support points. However, among these support points, there are always two support points furthest from each other along the first direction 101 and two support points furthest from each other along the third direction 103. The third direction 103 is the direction perpendicular to both the first direction 101 and the second direction 102 when the pruning machine is in a side-mounted position; that is, the third direction 103 is the left-right direction of the pruning machine. This application uses three support points on the pruning machine as an example for specific explanation: the three support points are the first support point A, the second support point B, and the third support point C.
[0060] The positional relationship between the first support point A, the second support point B, and the third support point C is described in detail below, with the explanation based on the perspective of the surfaces of the three support points in contact with the working plane:
[0061] In some embodiments, Figure 10a This is a schematic diagram showing the positions of the three support points in one embodiment. The first support point A is located at the foremost position, the second support point B is located at the rearmost position, and the third support point C is located between the two. In this configuration, the first support point A and the second support point B are the two support points furthest apart along the first direction 101, and the second support point B and the third support point C are the two support points furthest apart along the third direction 103.
[0062] In some embodiments, Figure 10b This is a schematic diagram showing the positions of the three support points in one embodiment. The first support point A is located at the foremost position, while the second support point B and the third support point C are both located at the rearmost positions. The line connecting the second support point B and the third support point C is parallel to the third direction 103. In this configuration, the first support point A and either the second support point B or the third support point C are the two support points furthest apart along the first direction 101, and the third support point C and the second support point B are the two support points furthest apart along the third direction 103.
[0063] In some embodiments, Figure 10c This is a schematic diagram illustrating the positions of the three support points in one embodiment. The first support point A is located at the foremost position, the second support point B is located at the rearmost position, and the third support point C is located between the two. The line connecting the first support point A and the second support point B is parallel to the first direction 101. In this configuration, the first support point A and the second support point B are the two support points furthest apart along the first direction 101, and the first support point A or the second support point B and the third support point C are the two support points furthest apart along the third direction 103.
[0064] In some embodiments, Figure 10d This is a schematic diagram showing the positions of the three support points in one embodiment. The first support point A is located at the foremost position, while the second support point B and the third support point C are both located at the rearmost positions. The line connecting the first support point A and the second support point B is parallel to the first direction 101, and the line connecting the second support point B and the third support point C is parallel to the third direction 103. In this configuration, the first support point A and the second support point B or the third support point C are the two support points furthest apart along the first direction 101, and the first support point A or the second support point B and the third support point C are the two support points furthest apart along the third direction 103.
[0065] Therefore, the sides of the triangle formed by the lines connecting the three support points can intersect both the first direction 101 and the third direction 103, or one side of the triangle can be parallel to the first direction 101, or one side of the triangle can be parallel to the third direction 103, or one side of the triangle can be parallel to the first direction 101 and the other side of the triangle can be parallel to the third direction 103.
[0066] The cutting assembly 200 also includes a leaf collector 240, which is connected to the other side of the blade support 230 that is not connected to the first blade 210 and the second blade 220. That is, the first blade 210 and the second blade 220 are located on one side of the blade support 230, and the leaf collector 240 is located on the other side of the blade support 230. In some embodiments, such as... Figure 7As shown, when the pruning machine is in a side-mounted position, the cutting assembly 200 abuts against the working plane, that is, the leaf collector 240 abuts against the working plane. In some embodiments, such as Figure 5 As shown, when the pruning machine is in a side-mounted position, the cutting component 200 does not contact the working plane, that is, the leaf collector 240 does not contact the working plane.
[0067] In some embodiments, when the pruning machine is in a side-mounted position and the cutting assembly 200 is not in contact with the working surface, all three support points are located on the handle assembly 500, that is, the first handle 510 includes at least one support point, and the connector 530 includes at least two support points. Figure 5 As shown, the first support point A is located on the first handle 510, and the second support point B and the third support point C are both located on the connector 530. Figure 4 for Figure 5 A diagram showing the pruning machine in its upright position. Figure 4 The positions of the first support point A, the second support point B, and the third support point C are... Figure 5 A schematic diagram corresponding to the support points in contact with the working plane. Connector 530 includes a first connector 531 and a second connector 532, which are connected. The included angle Q formed by the first connector 531 and the second connector 532 is greater than 0 degrees and less than 180 degrees, meaning the first connector 531 and the second connector 532 are not on a straight line. Optionally, the second support point B and the third support point C are located on the first connector 531 and the second connector 532, respectively. Optionally, the second support point B and the third support point C are located on the first connector 531 and at the connection point 533 between the first connector 531 and the second connector 532, respectively. Optionally, the second support point B and the third support point C are located on the second connector 532 and at the connection point 533 between the first connector 531 and the second connector 532, respectively. The positional relationships of the first support point A, the second support point B, and the third support point C are as described above in this application, and will not be repeated here.
[0068] In some embodiments, when the pruning machine is in a side-mounted position and the cutting assembly 200 abuts against the working surface, three support points are located on the handle assembly 500 and the cutting assembly 200, that is, the cutting assembly 200, the first handle 510, and the connector 530 each include at least one support point. Figure 7 As shown, the first support point A is located on the leaf collector 240, the second support point B is located on the connector 530, and the third support point C is located on the first handle 510. Figure 6 for Figure 7 A diagram showing the pruning machine in its upright position. Figure 6 The positions of the first support point A, the second support point B, and the third support point C are... Figure 7A schematic diagram corresponding to the support points in contact with the working plane. The positional relationships of the first support point A, the second support point B, and the third support point C are as described above in this application and will not be repeated here. Furthermore, the angle Q formed by the first connecting member 531 and the second connecting member 532 is not limited; the first connecting member 531 and the second connecting member 532 may or may not be on the same straight line.
[0069] When the angle M between the second direction 102 and the working plane (i.e., the horizontal plane) is greater than or equal to 45 degrees and less than or equal to 90 degrees, that is, when the pruning machine is in a side-mounted position, the first support point A, the second support point B, and the third support point C form a triangular support range S, and the projection of the pruning machine's center of gravity G onto the working plane lies within the triangular support range S. Specifically, the projection of the pruning machine's center of gravity G onto the working plane falling within the triangular support range S includes either the projection of the pruning machine's center of gravity G onto the working plane being located inside the triangle of the triangular support range S, or the projection of the pruning machine's center of gravity G onto the working plane being located on the side of the triangle of the triangular support range S. Since the above application defines the positional relationship of the three support points in various cases, the triangular support range S formed by the three support points includes corresponding multiple cases, which will not be elaborated here. Figures 10a to 10d This is a schematic diagram showing the projection of the center of gravity G of the pruning machine in some embodiments onto the working plane within the triangular support range S.
[0070] like Figure 4 and Figure 5 As shown, Figure 5 This is a schematic diagram illustrating three support points supporting a pruning machine placed on its side, as in one embodiment. When the battery pack 400 is not connected to the battery pack connection portion 110, the three support points can support the pruning machine to stand stably. Figure 5 Corresponding Figure 4 The projection of the pruning machine's center of gravity G onto the working plane lies within the triangular support range S. For example... Figure 6 and Figure 7 As shown, Figure 7 This is a schematic diagram illustrating three support points supporting a pruning machine placed on its side, according to one embodiment. After the battery pack 400 is attached to the battery pack joint 110, the three support points can support the pruning machine to stand stably. Figure 7 Corresponding Figure 6 The projection of the center of gravity G of the pruning machine onto the working plane is also within the triangular support range S. Therefore, when the pruning machine is in a side-mounted position, regardless of whether the battery pack 400 is connected to the battery pack connection part 110, the projection of the center of gravity G of the pruning machine onto the working plane is always within the triangular support range S, and the three support points can always stably support the pruning machine to stand on the working plane.
[0071] In some embodiments, along the first direction 101, the distance between the center of gravity G of the pruning machine and the foremost point of the pruning machine is a first distance D1, and the distance between the center of gravity G of the pruning machine and the rearmost point of the pruning machine is a second distance D2. The foremost point of the pruning machine is the foremost point of the cutting assembly 200, and the rearmost point of the pruning machine is the rearmost point of the second handle 520. The ratio of the second distance D2 to the first distance D1 is greater than or equal to 0.05 and less than or equal to 1. That is, the center of gravity G of the pruning machine is more biased towards the rear end or located in the middle of the machine along the first direction 101, allowing the pruning machine to stand stably on the working surface when in a side-mounted position.
[0072] Furthermore, as described above in this application, the first handle 510 and the second handle 520 are located on the front and rear sides of the battery pack joint 110, and the length X1 of the battery pack joint 110 is greater than the length X2. The longer side of the battery pack 400 is connected to the battery pack joint 110 along the second direction 102, which further improves the stability of the pruning machine standing on the working plane when it is in the side-lying state.
[0073] This application, by configuring the cutting assembly and handle assembly (or only the handle assembly) to a structure that allows the pruning machine to stand upright on the working plane when the cutting blade is perpendicular to or at an angle to the working plane, thus placing the pruning machine in a side-mounted position. This eliminates the need for users to insert the battery pack horizontally from the side of the pruning machine when it is upright. When the pruning machine is in the side-mounted position, users can easily install or replace the battery pack in a direction parallel to the extension direction of the cutting blade, i.e., perpendicular to the working plane, or vertically at an angle to the working plane. Furthermore, the weight of the battery pack itself can assist in its installation. For large-capacity battery packs, or in situations requiring frequent battery pack installation or replacement, the side-mounted position significantly improves the user experience.
[0074] Figure 11 The relative positions of the first handle 510 and the center of gravity G of the pruning machine in one embodiment are as follows: Figure 11 As shown, in a direction parallel to the third direction 103, the first handle 510 is located below the center of gravity G of the pruning machine. Specifically, whether the battery pack 400 is attached to the battery pack connection portion 110 or not, the first handle 510 is always located below the center of gravity G of the pruning machine. Furthermore, this application does not limit the relative position of the first handle 510 and the center of gravity G of the pruning machine; it is sufficient that the first handle 510 is connected to the front cover 120 and is located below the center of gravity G of the pruning machine in the third direction 103. The aforementioned vertical direction is based solely on… Figure 11The direction parallel to the third direction 103 is determined vertically. If from... Figure 1 From the perspective of the whole machine, the first handle 510 is always located to the right of the center of gravity G of the pruning machine.
[0075] Figure 12 In one embodiment of the pruning machine, the direction in which the battery pack 400 is attached to the battery pack attachment portion 110 is perpendicular to the extending directions of the first blade 210 and the second blade 220, that is, the direction in which the battery pack 400 is attached to the battery pack attachment portion 110 is perpendicular to the second direction 102. Figure 12 As shown, the center of gravity of the battery pack 400 is G1, and the center of gravity of the pruning machine is G. In a direction parallel to the second direction 102, the distance between the center of gravity G1 of the battery pack 400 and the center of gravity G of the pruning machine is D3, and the width of the gearbox 130 is D4. D3 is greater than 20% of D4. Optionally, D3 can be 23% of D4. Optionally, D3 can be 30% of D4. Optionally, D3 can be 50% of D4. Optionally, D3 can be greater than D4.
[0076] Figure 12 This is one embodiment in which the center of gravity G1 is located above the center of gravity G in a direction parallel to the second direction 102. Optionally, in a direction parallel to the second direction 102, the G1 of the battery pack 400 can be located below the center of gravity G, in which case D3 is still greater than 20% of D4. Optionally, the battery pack 400 can be tilted and connected to the pruning machine at a certain angle, that is, the battery pack connection part 110 is formed at a certain angle on the pruning machine, in which case D3 is still greater than 20% of D4. When the battery pack 400 is connected to the battery pack connection part 110 provided between the two handles, regardless of the specific setting position or setting angle of the battery pack connection part 110, after the battery pack 400 is connected to the battery pack connection part 110, the distance D3 between the center of gravity G1 of the battery pack 400 and the center of gravity G of the entire pruning machine is always greater than 20% of the width D4 of the gearbox 130.
