Embodiments for Carrying Out the Invention

[0033] Hereinafter, in order to more clearly illustrate the technical problems to be solved by the present application, the technical solutions adopted, and the technical effects achieved, the technical solutions of the embodiments of the present application will be described in more detail with reference to the drawings. However, the described embodiments are only some embodiments of the present application, not all embodiments.

[0034] In the description of the present application, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in FIG. 1, and is only for facilitating the description of the present application and simplifying the description, and does not indicate or imply that the mentioned device or element must have a specific orientation and be configured and operated in a specific orientation. Also, terms such as "first", "second", etc. are only for distinguishing different structures or components, and cannot be understood as indicating or implying relative importance. "About" according to the present application means within a range of plus or minus 5% based on the original numerical value.

[0035] The present application relates to a power equipment applied to a power tool. The power equipment generally integrates a power supply device, an output assembly, and a control board including electronic elements, and is supported by a housing and attached to the power tool for use. In actual applications, the power equipment is often used instead of an engine and can be adapted to various power tools such as lawn mowers, snow blowers, trimmers, sprinklers, compressors, high-pressure washers, and woodworking machines, and plays an important role in many fields of gardening, construction, agriculture, and daily life.

[0036] As shown in FIG. 1, in one embodiment, the power equipment 10 includes an output assembly 100, a power supply device 300, and a housing 200 that supports the output assembly 100 . The output assembly 100 includes an output shaft 110 for outputting power, and the output shaft 110 is configured to be rotatable about a first axis 111. The power supply device 300 provides an energy source for the output assembly 100. In this embodiment, the power supply device 300 includes at least a first battery pack 310 and a second battery pack 320.

[0037] As shown in FIGS. 2 and 3, the housing 200 includes a pedestal 210. The pedestal 210 defines a bottom plane 211 that enables the power equipment 10 to be placed on a receiving plane 220, and the bottom plane 211 is parallel to the receiving plane 220. It should be noted that the receiving plane 220 may be a surface for fixing the power equipment 10 in a power tool, or a surface on which the power equipment 10 is placed on the power tool when the power equipment 10 and the power tool are used together. The pedestal 210 may be a mounting seat for removably attaching the power equipment 10 to the power tool, or a structure in the power equipment 10 for stabilizing the placement when the power equipment 10 drives the operation of the power tool. That is, the power equipment 10 according to the present application is a horizontal-axis power equipment.

[0038] The output shaft 110 does not protrude from the pedestal 210 and protrudes from the front side of the housing 200. In this embodiment, on the front side of the housing 200, Base what contacts the 210 is the side wall 230, and the output shaft 110 protrudes from the side wall 230. The distance between the output shaft 110 and the bottom plane 211 is 5 millimeters or more. Here, if the first axis 111 of the output shaft 110 intersects the bottom plane 211, the distance between the output shaft 110 and the bottom plane 211 is the distance from an end of the output shaft 110 close to the bottom plane 211 to the bottom plane 211. A through hole 231 is formed in the side wall 230 through which the output shaft 110 protrudes outside the housing 200 along the first axis 111.

[0039] If there is a substantially flat surface at the lowermost end of the pedestal 210 for placement on a power tool, the bottom plane 211 is a plane formed at the lowermost end of the pedestal 210. When the pedestal 210 is placed on a power tool by a structure such as a stand, a stringer, or a structure with a non-flat surface, it should be noted that the bottom plane 211 is a "virtual" plane formed at the lowermost end of the pedestal 210 that enables the power equipment 10 to be placed on the receiving plane 220.

[0040] In this embodiment, the power equipment 10 is provided with screw holes in the pedestal 210, and by passing screws through the screw holes, fixation with the power tool is realized. In some embodiments, the power equipment 10 may be fixed to the power tool via a positioning structure on the side wall 230, such as screws, fasteners, hooks, etc. In some embodiments, the power equipment 10 may be provided with fixing structures on both the pedestal 210 and the side wall 230 to achieve the fixing effect.

[0041] In one embodiment, the side wall 230 includes a front side wall 232 through which the output shaft 110 passes and projects outside the housing 200. The side wall 230 further includes a rear side wall 233 opposite to the front side wall 232, and a left side wall 234 and a right side wall 235 provided between the front side wall 232 and the rear side wall 233. In the embodiments shown in FIGS. 2 and 3, the left side wall 234 includes a first left side wall 2341, a second left side wall 2342, and a third left side wall 2343, and the right side wall 235 includes a first right side wall 2351, a second right side wall 2352, and a third right side wall 2353. The side wall 230 may be planar or curved, and may have an opening or be completely closed.

[0042] The output shaft 110 is inserted into the shaft hole of the power tool and drives the operating shaft of the power tool to rotate when the output shaft 110 rotates. When the power equipment 10 is a direct drive of the motor, the first axis 111 of the output shaft 110 coincides with the motor axis. When there is a transmission structure, such as a gear transmission or a belt transmission, in the power equipment, the output shaft 110 is a shaft that projects from the power equipment 10 and drives the power tool to move. It should be noted that an intermediate shaft may be separately added to the output shaft 110 to match power tools with different shaft holes.

[0043] As shown in FIGS. 4 and 5, between the first battery pack 310 and the second battery pack 320 is substantially symmetric with respect to a symmetry plane 330. The first battery pack 310 is provided on one side of the symmetry plane 330, and the second battery pack 320 is provided on the other side of the symmetry plane 330 symmetrically with respect to the first battery pack 310. There is a preset distance L interval between the first axis 111 of the output shaft 110 and the symmetry plane 330. The preset distance L is greater than zero. FIG. 5 is a front view when viewed directly in front of the structure of FIG. 4. In FIG. 5, the intersection line between the symmetry plane 330 and the plane of the paper where FIG. 5 is located forms a first intersection line 331, and the first axis 11 1 The distance between 1 and the first intersection line 331 is the preset distance L. In this embodiment, the first battery pack 310 is provided on the right side of the symmetry plane 330, and the second battery pack is provided on the left side of the symmetry plane 330.

[0044] In this embodiment, the first battery pack 310 is detachably attached to the housing 200 along the direction of the first straight line 311, and the second battery pack 320 is detachably attached to the housing 200 along the direction of the second straight line 321. The first straight line 311 is substantially parallel to the bottom plane 211, and the second straight line 321 is also substantially parallel to the bottom plane 211. That is, the removal directions of the first battery pack 310 and the second battery pack 320 are both substantially parallel to the bottom plane 211. Here, it should be noted that the "substantially parallel" mentioned in this article means that the included angle between the straight line and the plane may be 10 degrees or less. In this embodiment, the removal directions of the first battery pack 310 and the second battery pack 320 are both substantially parallel to the first axis 111 of the output shaft 110.

[0045] Figures 6a to 6k, 6m, 6n, and 6p disclose a plurality of embodiments of the present application. However, these figures are only some schematic diagrams related to the present application and do not cover all possibilities. The first battery pack (310a, 310b, 310c, 310d) has a plurality of arrangement methods, and the second battery pack (320a, 320b, 320c, 320d, 320e, 320f) also has a plurality of arrangement methods.

[0046] In one embodiment, the first straight line 311 of the first battery pack 310 is substantially parallel to the operating plane of the power equipment 10, and the second straight line 321 of the second battery pack 320 is substantially parallel to the operating plane. The operating plane is the plane defined when the power equipment 10 is placed on one operating surface. In one embodiment, the operating plane is, that is, the receiving plane 220 of the power tool. Therefore, the insertion and removal directions of the first battery pack 310 and the second battery pack 320 are both parallel to the operating plane.

[0047] In one embodiment, as shown in FIGS. 4, 6k, and 6m, the first battery pack 310 is provided above the output shaft 110, and the second battery pack 320 is also provided above the output shaft 110. There is a symmetry plane 330 between the first battery pack 310 and the second battery pack 320.

[0100] Regarding the outer diameter of the motor, it should be noted that when the motor 120 is an inner rotor motor, the outer diameter of the motor 120 is the diameter of the stator of the inner rotor motor, that is, the diameter of the stack. When the motor 120 is an outer rotor motor, the outer diameter of the motor 120 is the diameter of the rotor sleeve of the outer rotor motor. The outer diameter D1 of the motor 120 is 75 mm or more. In some embodiments, the outer diameter D1 may be 85 mm, 95 mm, 105 mm, 115 mm, 125 mm, 135 mm, or 145 mm.

[0101] The Ratio ratio of the diameter of the output shaft 110 to the outer diameter of the motor is 0.069 or more and 0.4 or less.

[0102] The total capacity of the power supply device 300 is the sum of the electrical capacities of all the battery packs of the power supply device 300. In this embodiment, when the power supply device 300 includes only one battery pack, the minimum value of the total capacity of the power supply device 300 is 2 Ah. In one embodiment, when the power supply device 300 includes two battery packs, the total capacity of the power supply device 300 may be 24 Ah. In one embodiment, when the power supply device 300 includes three battery packs and one of them is a backpack-type battery pack, the total capacity of the power supply device 300 may be 52 Ah. The product of the total capacity of the power supply device 300 and the maximum output power of the motor 120 is 1000 W·Ah or more.

[0103] In one example, the total capacity of the power supply device 300 is 2 Ah or more and 52 Ah or less. In one example, the power supply device 300 includes two battery packs, and the electrical capacity of each of these two battery packs is 10 Ah. In one example, the power supply device 300 may include two battery packs with different capacities. If the total capacity of the power supply device 300 is too large, the weight of the power supply device will be excessive, which may affect the portability of the power equipment 10.

[0104] The power supply device 300 may include different types of battery units (also called battery cells), that is, the power supply device 300 may include battery cells with one or more different characteristics. The battery cells may have different physical sizes (e.g., different diameters, different lengths, etc.), shapes (e.g., cylindrical, prismatic, etc.), chemical compositions (e.g., different lithium-based ones or other chemical compositions), operating characteristics (e.g., electrical capacity (Ah), temperature performance, nominal voltage, etc.), etc., and the battery cells may have various combinations of the above various characteristics. The chemical composition of the battery cells may be lithium batteries, lithium iron phosphate batteries, lithium carbon capacitor batteries, etc. The outer packaging of the battery cells may be a deformable structure. For example, when a chemical reaction occurs, the battery cells expand and deform. The first battery pack 310 includes the first battery cell 350, the second battery pack 320 includes a second battery cell (not shown), and the first battery cell and the second battery cell may have different materials or different shapes.

[0105] The first battery pack 310 and the second battery pack 320 may have different physical sizes, shapes, chemical compositions, operating characteristics, etc., or may have different combinations of these different characteristics.

[0106] In one embodiment, the first battery pack 310 includes a first battery cell 350 provided within the housing 200. The second battery pack 320 and the housing form a removable connection, and the housing 200 is formed with a battery pack coupling portion 340 to which the second battery pack 320 is removably attached.

[0107] As shown in FIG. 21, in one embodiment, between the first battery pack 310 and the second battery pack 320, one is fixed to the housing 200 of the power equipment 10, and the other is removably provided to the power equipment 10. The first battery pack 310 or the second battery pack 320 fixed to the housing 200 is defined as a "fixed battery pack", and the other removable one is called a "removable battery pack". The operator cannot remove or attach the "fixed battery pack" to the power equipment 10 by himself / herself. The "fixed battery pack" can be removed only when the operator removes the housing 200 of the power equipment 10 with a separate tool (such as a screwdriver, a driver, etc.) or when the housing of the power equipment 10 is damaged. For the "removable battery pack", in some embodiments, the operator can usually realize the removal of the "removable battery pack" only by operating the removal button on the power equipment 10. Therefore, when charging the "fixed battery pack", it is necessary to operate by inserting the charging power source into the port location of the power equipment 10.

[0108] In one embodiment, the first battery pack 310 is configured to be removable from the housing 200 to supply power to another power tool, and the housing 200 is formed with a battery pack coupling portion 340 to which the first battery pack 310 can be removably attached.

[0109] In one embodiment, the first battery pack 310 is attached to the housing 200, the second battery pack 320 is separable from the housing 200 of the power equipment 10, and is configured to be able to supply power to the power equipment 10 even when the second battery pack 320 is separated from the housing 200. The "separation" here refers to spatial separation, that is, mechanical separation. It should be noted that when the power equipment 10 is in an operating state, the electrical connection between the second battery pack 320 and the power equipment 10 is still maintained. In one embodiment, when the second battery pack 320 is placed outside the housing 200, the second battery pack can maintain an electrical connection with the housing.

[0110] In one embodiment, the power equipment 10 includes a control board 420, the control board 420 includes electronic components for controlling the motor 120, and the second battery pack 320 is configured to be connectable to the control board 420. In one embodiment, the second battery pack 320 can be carried and used by the user. In one embodiment, the power equipment 10 has a first coupling portion, the second battery pack 320 has a first mounting portion, and the first mounting portion of the second battery pack 320 can be mounted to the first coupling portion of the power equipment 10. In one embodiment, the first coupling portion is located at the top or side wall 230 of the power equipment.

[0111] In one embodiment, the second battery pack 320 has a second mounting portion, and the second mounting portion enables the second battery pack 320 to be mounted on a flat surface. This flat surface may be a surface located on the power tool, or a surface located on the power equipment 10, or a surface located outside the power tool, such as a wall near the power tool. In one embodiment, the second battery pack has a second mounting portion, and the second mounting portion can be suspended, slidably mounted, pivotally mounted, or pushably mounted. In one embodiment, the second mounting portion of the second battery pack may be mounted to the power equipment. In one embodiment, the second mounting portion of the second battery pack may be mounted to the power tool combined with the power equipment.

[0112] As shown in FIGS. 8 and 15, the motor 120 has an external air guiding passage 630, and the air guiding passage 630 dissipates heat from the motor 120. As shown in FIG. 15, the housing 200 of the power equipment 10 has an air inlet 610 and an air outlet 620. In this embodiment, the air inlet 610 and the air outlet 620 are located on both sides of a vertical plane passing through the first axis 111 of the output shaft 110.

[0113] As shown in FIG. 20, the battery pack coupling part 340 attaches the power supply device 300 to the housing 200, and the battery pack coupling part 340 has pole pieces so that an electrical connection is realized between the battery pack and elements such as the control board 420 inside the housing 200. The power equipment 10 includes a first locking assembly 710 and an auxiliary locking assembly 700. The first locking assembly 710 and the auxiliary locking assembly 700 jointly fix and attach the first battery pack 310 to the battery pack coupling part 340, so that the first battery pack 310 does not loosen or fall off from the housing 200 even under huge vibrations, and at the same time increases the anti-theft performance of the first battery pack 310. When the power equipment 10 further includes a second battery pack 320, the first locking assembly 710 can also prevent the second battery pack 320 from falling off.

[0114] Hereinafter, one embodiment of the first locking assembly will be introduced first. As shown in FIGS. 20 to 21, the first locking assembly 710 has at least a locking position and an unlocking position. In FIG. 20, the first locking assembly 710 is in the locking position, and in FIG. 21, the first locking assembly 710 is in the unlocking position. The first locking assembly 710 includes a locking hole 711, and the user needs to use a first unlocking tool to switch the first locking assembly 710 between the locking position and the unlocking position. When the first locking assembly 710 is in the locking position, the first locking assembly 710 restricts the movement of the first battery pack 310. When the first locking assembly 710 is in the unlocking position, the first locking assembly 710 does not restrict the movement of the first battery pack.

[0115] The first locking assembly 710 further includes a first end 712 and a second end 713. The first end 712 and the second end 713 are respectively located on both sides of the locking hole 711, and the connecting lines from the first end 712 and the second end 713 to the locking hole 711 respectively form substantially a straight line. When the first locking assembly 710 is in the unlocking position, neither the first end 712 nor the second end 713 blocks the insertion / removal path of the first battery pack 310 and the second battery pack 320. When the first locking assembly 710 is in the locking position, the first end 71 2 blocks one side of the first battery pack 310 so that the first battery pack 310 cannot be inserted or removed, and the second end 713 blocks one side of the second battery pack 320 so that the second battery pack 320 cannot be inserted or removed.

[0116] FIGS. 22 and 23 show another embodiment of the first locking assembly. The first locking assembly 720 includes a locking member 721 and a locking plate 722. In this embodiment, the locking plate 722 has one locking hole 7221, and the locking member 721 passes through the locking hole 7221 to fix the locking plate 722 to the housing 200. In one embodiment, the locking member 721 is an outer hexagonal screw. In some embodiments, the locking member 721 may further be an inner hexagonal screw or a Torx (Registered Trademark) screw. The user can tighten or loosen the locking member 721 with a common removal tool, such as a monkey wrench. One end of the locking member 721 is an operation head 7211, and the other end has a male screw 7212. The removal tool acts on the operation head 7211 to screw the locking member 721 in or out. Therefore, in this embodiment, the first unlocking tool is a wrench, and the wrench can be used to tighten or loosen an outer hexagonal screw that matches a common size. The wrench may be obtained by the user himself, or may be connected to the power equipment 10 for the user's convenience.

[0117] FIGS. 23 and 24 show two embodiments of the locking plate 722.

[0118] The locking plate 722 shown in FIG. 23 includes a first baffle plate 7222 and a second baffle plate 7223, and the first baffle plate 7222 and the second baffle plate 7223 block the edges of the two battery packs respectively. The locking plate 722 further includes a first connecting plate 7225 forming an included angle with the first baffle plate 7222 and a second connecting plate 7226 forming an included angle with the second baffle plate 7223. The first connecting plate 7225 and the second connecting plate 7226 are connected by a third connecting plate 7224, and the locking hole 7221 is located on the third connecting plate 7224. The first baffle plate 7222, the first connecting plate 7225, the third connecting plate 7224, the second baffle plate 7223 and the second connecting plate 7226 jointly form a concave shape.

[0119] The first locking assembly 730 in FIG. 24 includes a locking member 731 and a locking plate 732. The locking member 731 in FIG. 24 is substantially consistent with the requirements of the locking member 721 in FIG. 23, and will not be repeatedly described here. The locking plate 732 in FIG. 24 is elongate, and both ends of the locking plate 732 block the two battery packs simultaneously.

[0120] Regarding the first locking assemblies of the type from FIG. 20 to FIG. 24, their function is that they can better fix the power supply device 300 in a large vibration operating situation. In some operating situations, the power equipment 10 may vibrate violently and the body may also tilt, which may not necessarily provide sufficient locking force to lock the power supply device 300 only with the auxiliary locking assembly 700. Therefore, the first battery pack 310 and / or the second battery pack 320 may become loose or fall off, or the mechanical structures of the auxiliary locking assembly 700 and the battery pack coupling part 340 may be deformed and damaged.

[0121] In one embodiment, the first unlocking tool may be a "key" that is only compatible with the power equipment 10. Thus, when the first locking assembly 710 is in the locked position, without the first unlocking tool, the first battery pack 310 cannot be removed. In this way, the safety of the first battery pack 310 is ensured and it is difficult for the first battery pack 310 to be stolen. After the user uses the first unlocking tool to unlock the first locking assembly 710, by operating the auxiliary locking assembly 700, the first battery pack 310 can be quickly removed. The auxiliary locking assembly 700 is operated by a single button 701. There is no need to use an unlocking tool, and the user can remove the first battery pack 310 by pressing the button 701.

[0122] Figures 25 to 30 show one embodiment of the first unlocking tool 744.

[0123] The power equipment 10 further includes a second locking assembly 760. The second battery pack 320 is fixed to the power equipment 10 by the second locking assembly 760. The second locking assembly 760 has a locked position and an unlocked position. When the second locking assembly 760 is in the locked position, the second locking assembly 760 restricts the movement of the second battery pack 320. When the second locking assembly 760 is in the unlocked position, the second locking assembly 760 does not restrict the movement of the second battery pack 320.

[0124] As shown in Figure 25, the first unlocking tool 744 is similar in structure to a "key", and the first locking assembly 740 is similar in structure to a "keyhole". The first locking assembly 740 is provided on the housing 200 of the power equipment 10. The first unlocking tool 744 can drive the first locking assembly 740 to perform locking or unlocking operations so as to realize the attachment and detachment of the power supply device 300.

[0125] FIG. 26 is a schematic diagram when the first lock assembly 740 is in the locked position, FIG. 27 is a schematic diagram when the first lock assembly 740 is in the unlocked position, FIG. 28 is an exploded schematic diagram of the first lock assembly 740, FIG. 29 is a side sectional view of FIG. 26, and FIG. 30 is a side sectional view of FIG. 27.

[0126] The first lock assembly 740 includes a moving member 741, a fixing member 742, and an inserting member 743. One sliding groove 7411 is formed in the moving member 741. The fixing member 742 has a substantially right-angled triangle shape. One right-angled side 7422 of the fixing member 742 drives the inserting member 743 to move, and one hypotenuse 7421 of the fixing member 742 is inserted into the sliding groove 7411 to enable the movement of the fixing member 742 in the sliding groove 7411. In this embodiment, the sliding groove 7411 is a straight groove. In one embodiment, the sliding groove 7411 may be a spiral groove as long as there is a height difference between the upper and lower ends of the sliding groove 7411. As shown in FIG. 27, the power supply device 300 is provided with a lock port 746 for the first lock assembly 740 to lock or unlock. The inserting member 743 has a first groove 7431 for fitting with the fixing member 742, whereby the movement of the fixing member 742 can drive the movement of the inserting member 743. The driving member 743 further includes an overhanging portion 7432.

[0127] When the first unlocking tool 744 is inserted into the hole 7412 above the moving member 741 and pushed downward, the moving button 741 starts to move from the locked position shown in FIGS. 26 and 29. When the moving button 741 moves to the bottommost position downward, that is, the unlocked position shown in FIGS. 27 and 30, the overhanging portion 7432 is moved out of the lock port 746, thereby realizing the unlocking of the power supply device 300. There is a first elastic member 745 between the inserting member 743 and the power supply device 300, whereby the inserting member 743 can be automatically reset when the first unlocking tool 744 is taken out from the moving member 741.

[0128] FIG. 31 shows a specific embodiment of the first unlocking tool 751. The first unlocking tool 751 is connected to the power equipment 10 via the first connecting member 753. In one embodiment, the first connecting member 753 may be connected inside the power equipment 10 or may be connected outside the power equipment 10 via a hook or the like, thereby preventing the loss of the first unlocking tool 751. The power equipment 10 is provided with a third locking structure 752. When the first unlocking tool 751 is fitted to the third locking structure 752 and an operation is performed by the user, the power supply device 300 can be unlocked. For example, when the first unlocking tool 751 is fitted to the third locking structure 752 and pushed downward, the first battery pack 310 can be removed. In one embodiment, the first unlocking tool 751 is provided with a fitting structure, and the third locking structure 752 is provided with a receiving structure. When the fitting structure and the receiving structure are fitted, the third locking structure 752 can be driven to perform an unlocking operation, and the user's hand cannot directly unlock the third locking structure 752. The advantage of doing so is to prevent the power supply device 300 from accidentally escaping due to accidental contact or the like when the power equipment 10 operates in a complex operating situation. In some operating situations, the power supply device 300 is not parallel to the horizontal plane, or the mounting direction of the power supply device 300 and the output shaft 110 form an included angle. In this case, when the first unlocking tool 751 and the third locking structure 752 are separated, the escape of the power supply device 300 caused by the user accidentally triggering is prevented. The power equipment 10 may be provided with a storage space, such as a storage bin, for safely storing the first unlocking tool 751 for the user to use when needed.

[0129] It should be noted that the locking and unlocking methods of the various power supply devices 300 disclosed in FIGS. 20 to 31 can be used in combination. For example, the first locking assembly 710 and the first locking assembly 740 realize a double lock and can be used for locking the first battery pack 310 at the same time to prevent theft of the first battery pack 310.

[0130] In one embodiment, the power equipment 10 includes only one battery pack, i.e., the first battery pack 310. In one embodiment, the power equipment 10 includes the first battery pack 310 and the second battery pack 320. The first battery pack 310 is locked to the power equipment 10 by a first locking assembly, and the second battery pack 320 is locked to the power equipment 10 by a second locking assembly. The first unlocking tool can be used to unlock both the first locking assembly and the second locking assembly. In one embodiment, the power equipment 10 includes the first battery pack 310 and the second battery pack 320. Both the first battery pack 310 and the second battery pack 320 are locked to the power equipment 10 by a first locking assembly, and the first unlocking tool can unlock the first locking assembly and the second locking assembly simultaneously.

[0131] In connection with FIGS. 6k and 32, when viewed from the left side of the power equipment 10, the first battery pack 310 is removably attached to the power equipment 10 along a first straight line 311. In one embodiment, a first included angle α is formed between the first straight line 311 and the receiving plane 220, and the first included angle α is not less than 2 degrees and not more than 30 degrees. The installation of the second battery pack 320 is similar to that of the first battery pack 310. In this way, it is realized that an included angle is formed between the top surface 312 of the power supply device and the receiving plane 220. The advantage of doing so is that a drainage angle can be formed at the top of the power supply device 300 when it is raining, etc., so that water is not easily accumulated, and the service life of the power supply device is improved. On the other hand, when the battery pack is inclined, the user can save time when inserting and removing the battery pack.

[0132] Similarly, the top surface 312 of the power supply device 300 may be formed to form an included angle with the first straight line 311. When the first straight line 311 and the receiving plane 220 are substantially parallel, the top surface 312 and the receiving plane 220 are still held to form an included angle, thereby realizing a drainage effect equivalent to the above.

[0133] As shown in FIGS. 33 to 35, in order to extend the service life of the power supply device 300, it is necessary to consider heat dissipation in addition to drainage during the installation and use process of the power supply device 300. FIG. 35 is a partially enlarged view of the first region 201 in FIG. 34.

[0134] On the side of the housing 200, a first side wall 240 for enclosing the power supply device 300 is formed, and a heat dissipation part 241 is provided on the first side wall. The heat dissipation part 241 is composed of a plurality of heat dissipation grooves 242, and each heat dissipation groove 242 is covered by a top cover 243 so as to prevent rainwater from flowing into the heat dissipation groove 242 and immersing the power supply device 300. In addition, making the part of the housing 200 for placing the power supply device 300 have a structure that penetrates front and back can increase the air flow and further enhance heat dissipation. At the same time, making the part of the housing 200 for placing the power supply device 300 have a structure that penetrates front and back also facilitates the cleaning of the accommodation space of the power supply device 300, and all the dust generated when the power equipment 10 is attached to the power tool and operates can be easily removed.

[0135] As shown in FIGS. 34 and 36, on the top of the housing 200, a first top cover 250 for enclosing the power supply device 300 is formed. In one embodiment, the first top cover 250 is made of a material with a good heat dissipation effect of one type. For example, the first top cover 250 may be made of iron, and in this way, both the strength can be guaranteed and it has a fast heat dissipation rate.

[0136] In one embodiment, the first top cover 250 is made of two types of materials, which are the first material 251 and the second material 252 respectively. Among them, the first material 251 and the second material 252 have different heat dissipation capabilities, for example, different thermal conductivities. In one embodiment, since the second material 252 is closer to the power supply device 300, it has a higher thermal conductivity, and thus can help the power supply device dissipate heat quickly.

[0137] In addition, the first material 251 and the second material 252 may have different waterproof capabilities. For example, there are no holes on the surface of the first material 251, but several holes are provided in the second material 252. Thus, the first material 251 bears more waterproof functional effects, and the second material 252 bears more heat dissipation functional effects. The first material 251 is in direct contact with the external environment of the power equipment 10, and the second material 252 is closer to the power supply device 300. The heat of the power supply device 300 is absorbed by the second material 252 and then conducted to the first material 251, and then released to the surrounding environment by the first material 251.

[0138] Figures 32, 33, and 37 show another embodiment of the control device 500e.

[0139] As shown in FIG. 33, the control device 500e may be provided below the power supply device 300, or the control device 500e may be provided below at least one battery pack. The control device 500e includes a speed control element 510a, a main switch 511a, and a display interface 512a. The speed control element 510a, the main switch 511a, and the display interface 512a jointly form an observation interface 501a (see FIG. 32). In one embodiment, the observation interface 501a may be the side surface of the control device 500e with the largest area directly observable by the user. The user can observe parameters and information such as the rotation speed of the output shaft 110, the power amount of the power supply device 300, and the temperature of the power supply device 300 from the observation interface 501a. In one embodiment, the observation interface 501a includes at least the plane where the display interface 512a of the control device 500e is located.

[0140] There is a second included angle β between the observation interface 501a and the receiving plane 220, and the second included angle β is 10 degrees or more and 70 degrees or less. In one embodiment, the second included angle β is 10 degrees or more and 50 degrees or less. In some specific embodiments, the second included angle β may be 20 degrees, 30 degrees, or 40 degrees.

[0141] As shown in FIGS. 33, 37, and 38, the display interface 512a is located between the speed control element 510a and the main switch 511a. In this embodiment, the main switch 511a is provided with a keyhole 514, and the main key 513 is used to fit into the keyhole 514 of the main switch 511a so as to realize the switching of the power equipment 10 between different power positions. The main switch 511a has three power positions that are respectively set to "OFF", "ON", and "START" in the clockwise direction, and the user adjusts the operating state of the power equipment 10 by rotating the main key 513.

[0142] The control device 500e includes a switch control board 460, and the switch control board 460 is electrically connected to the main switch 511a. In this embodiment, the switch control board 460 is further electrically connected to the speed control element 510a and the display interface 512a. A hall plate 461 is provided on the switch control board 460. The hall plate 461 is electrically connected to the switch control board 460, and a hall element 462 is provided on the hall plate 461.

[0143] In one embodiment, instead of a hall sensor, a slide resistor may be used to control the magnitude of the rotational speed of the motor. For the power equipment 10 using a slide resistor, it is necessary to perform special waterproof sealing on the housing of the control device 500e. Therefore, from the perspective of waterproofing, the method of sensing using the hall element 462 does not require waterproof treatment and has more practicality.

[0144] As shown in FIG. 38, the speed control element 510a is a rotatable rotary knob, and a magnetic material 5101 is provided inside the speed control element 510a (the side close to the hall plate 461). The magnetic material 5101 rotates as the speed control element 510a rotates. FIGS. 40a and 40b show the state when the speed control element 510a is rotated at the first rotation speed, and FIGS. 41a and 41b show the state when the speed control element 510a is rotated at the second rotation speed. The hall element 462 senses different magnetic fluxes when the position of the magnetic material 5101 changes, feeds back the magnetic flux to the hall plate 461, and realizes the effect of adjusting the current.

[0145] The speed control element 510a further has a connection part 5102 (see FIG. 37). The connection part 5102 is used to connect to the control member 5001, and the control member 5001 may be a flexible rope, a wire, a rigid lever, or a combination of two or more of them. When the user pulls the control member 5001, one end of the control member 5001 pulls the connection part 5102 to rotate the speed control element 510a. In this embodiment, when the control member 5001 is pulled, the speed control element 510a rotates counterclockwise. That is, the user does not need to directly operate the speed control element 510a by hand and can adjust the angle, position, etc. of the speed control element 510a. Similarly, when the control member 5001 is pushed, the speed control element 510a rotates clockwise.

[0146] In this embodiment, the control device 500e includes one front cover plate 515. A main switch 511a is formed on the front cover plate 515, and the front cover plate 515 and the speed control element 510a are fitted together.

[0147] In connection with FIGS. 42 to 44, a damping material 5103 is attached between the speed regulating element 510a and the front cover plate 515. In one embodiment, the damping material 5103 is an O-ring. Due to the installation of the damping material 5103, when the speed regulating element 510a rotates, it is necessary to resist the resistance of the damping material 5103. In this way, the speed regulating element 510a can stop at the position where it is located when an external force on the speed regulating element 510a from the user's hand or the control member 5001 is removed due to the resistance of the damping material 5103.

[0148] As shown in FIG. 42, at least two rotational speeds, namely a first rotational speed 5151 and a second rotational speed 5152, are displayed on the front cover plate 515. The speed regulating element 510a controls the output rotational speed of the power equipment 10 to fall between the first rotational speed 5151 and the second rotational speed 5152. The speed regulating element 510a is further provided with an indicating portion, and the position where the indicating portion is combined is the current rotational speed. When the speed regulating element 510a is rotated to align the indicating portion at an arbitrary position between the first rotational speed 5151 and the second rotational speed 5152 and the hand or the control member 5001 is released, the speed regulating element 510a can be held at the current position due to the resistance provided by the damping material 5103, and the power equipment 10 outputs one rotational speed intervening between the first rotational speed 5151 and the second rotational speed 5152.

[0149] In connection with FIG. 43, the speed regulating element 510a has a first position regulating portion 5104, the front cover plate 515 has a second position regulating portion 5153, and the damping material 5103 is provided between the first position regulating portion 5104 and the second position regulating portion 5153. In this embodiment, the first position regulating portion 5104 is an engaging groove, and the second position regulating portion 5153 has a plurality of ribs for increasing friction.

[0150] In addition, in order for the speed control element 510a to be held at an arbitrary position, the present application provides a damping material 5103 to increase the frictional force between the speed control element 510a and the front cover plate 515, so that the power equipment 10 outputs one arbitrary rotational speed intervening between the first rotational speed 5151 and the second rotational speed 5152. That is, the rotational speed can be adjusted uniformly and smoothly. Other structures may be used to achieve this function in addition to the damping material 5103. In addition, the power equipment 10 may be configured to have a plurality of rotational speed positions so that the output rotational speed can only be adjusted between several fixed rotational speeds.

[0151] Now, returning to FIG. 38, the control device 500e further includes a wireless communication board 470 and a rear cover 480 for mounting the wireless communication board 470. A wireless communication unit 471 is provided on the wireless communication board 470, and an external device can communicate wirelessly with the wireless communication board 470 according to the Bluetooth (Registered Trademark) protocol or the Wi-Fi protocol. Therefore, the control device 500e integrates four functions: a power switch, a screen display, an output rotational speed adjustment, and wireless communication.

[0152] In connection with FIG. 45, the main switch 511a can control at least the start and stop of the motor 120. A power-on switch 5111 and a motor switch 5112 are provided in the main switch 511a. Hereinafter, the position shift operation of the main switch 511a will be described in detail. The main switch 511a has three positions, which are the "OFF" position, the "ON" position, and the "START" position, respectively. When the main switch 511a is adjusted to the "OFF" position, both the power-on switch 5111 and the motor switch 5112 are turned off. When the main switch 511a is adjusted to the "ON" position, the power-on switch 5111 is turned on and the motor switch 5112 is turned off. When the main switch 511a is adjusted to the "START" position, both the power-on switch 5111 and the motor switch 5112 are turned on.

[0153] When operation S111 is executed, the main switch 511a is adjusted from the "OFF" position to the "ON" position, and the power equipment 10 is immediately powered on, but the output shaft 110 does not rotate. When operation S112 is executed, the main switch 511a is adjusted from the "ON" position to the "START" position, and the output shaft 110 of the power equipment 10 immediately rotates. When operation S113 is executed, the main switch 511a is directly adjusted from the "START" position to the "OFF" position, the output shaft 110 of the power equipment 10 immediately stops rotating, and is powered off after the first preset time. In one embodiment, the first preset time may be 4 seconds, 5 seconds, or 6 seconds. When operation S114 is executed, the main switch 511a is adjusted from the "START" position to the "ON" position, and the output shaft 110 of the power equipment 10 immediately stops rotating, but is not powered off. When operation S115 is executed, the main switch 511a is adjusted from the "ON" position to the "OFF" position, and the power equipment 10 is powered off after the second preset time. The second preset time here may be the same as or different from the first preset time. In one embodiment, the second preset time may also be 4 seconds, 5 seconds, or 6 seconds. When operation S116 is executed, the main switch 511a is directly adjusted from the "OFF" position to the "START" position, the power equipment 10 is immediately powered on, and the output shaft 110 immediately rotates.

[0154] The display interface 512a may be made of LED, LCD, or other light-emitting materials, that is, the display interface 512a may be an LED display interface or an LCD display interface, etc. The display interface can display at least one of information such as the power amount of the power supply device, the total operating time of the power equipment, the Bluetooth connection information, the operating information of the power supply device, the output rotation speed of the power equipment, the temperature information of the power equipment, and the fault information of the power equipment.

[0155] One display mode of the display interface 512a is as shown in FIG. 46. The information shown on the display interface 512a includes power consumption 5121, total operating time 5122, Bluetooth connection icon 5123, power supply unit operation information 5124, output rotation speed 5125, overheat warning 5126, rotation jam warning 5127, fault code 5128, etc.

[0156] The top layer of the display interface 512a includes the total operating time 5122 and the Bluetooth connection icon 5123. The total operating time 5122 is the total operating time accumulated from the first operation of the power equipment 10 until now. The user can determine whether each component needs to be maintained or replaced based on the total operating time 5122. The Bluetooth connection icon 5123 is used to indicate whether the Bluetooth connection function of the power equipment 10 is turned on. For example, when the Bluetooth connection icon 5123 is lit, the power equipment 10 has the ability to connect to another mobile device via Bluetooth.

[0157] In the middle of the display interface 512a, power supply device operation information 5124 and power quantity 5121 are included. The power supply device operation information 5124 includes battery pack icons labeled "1" and "2", and is used to display the number of the battery pack of the currently power-supplying power supply device 300. For example, when the label "1" is lit, it indicates that the currently power-supplying is the first battery pack 310, and when the label "2" is lit, it indicates that the currently power-supplying is the second battery pack 320. That is, at the same time, only one battery pack may supply power, or two battery packs may supply power simultaneously. In one embodiment, the power quantity 5121 can display the power quantity of the currently power-supplying battery pack. In another embodiment, the user can select a certain battery pack and make the display interface 512a display the power quantity 5121 of the selected battery pack. The power quantity 5121 here can be expressed in the form of a percentage. For example, 40% means that the remaining power quantity (i.e., the available power quantity) of the selected battery pack is 40% of the full charge power quantity of the battery pack. The power quantity 5121 may also be expressed in the form of time. For example, by displaying "4h", it can indicate that the battery pack can still be used for another 4 hours under the current operating conditions.

[0158] The output rotation speed 5125 is used to display the rotation speed output when the power equipment 10 is operating. As shown in FIG. 46, the higher the scale value lit by the output rotation speed 5125, the greater the rotation speed of the output shaft 110. The output rotation speed 5125 is provided on the right side of the screen of the display interface 512a and is arranged in the vertical direction. Such an installation conforms to the observation habit of the human eye, and the rotation speed output by the output shaft 110 can be clearly seen.

[0159] The bottom layer of the display interface 512a is subject to maintenance and fault attention. When the overheat warning 5126 is lit, it alerts the user that the temperature of the power equipment 10 is too high. When the rotation stall warning 5127 is lit, it alerts the user that there is a rotation stall in the power equipment 10. The fault code 5128 is used to display the number of the occurred fault, and the user can search for the type of the fault occurred in the power equipment 10 according to the number.

[0160] Figure 47 is a functional schematic diagram of the control system of the power equipment 10. Among them, the power management board 410 is provided with a first controller 411, the control board 420 is provided with a second controller 421, and the switch control board 460 is provided with a third controller 463. In one embodiment, the first controller 411, the second controller 421, and the third controller 463 are MCU controllers. In other embodiments, the first controller 411, the second controller 421, and the third controller 463 may be CPU controllers, MPU controllers, DSP controllers, etc.

[0161] The power management board 410 is further provided with a power processing unit 412. The power processing unit 412 can selectively use one or two of the battery packs to discharge according to the high and low output voltages of the first battery pack 310 and the second battery pack 320. The power processing unit 412 can also determine whether the first battery pack 310 and the second battery pack 320 are in a normal state. The control board 420 is provided with a voltage conversion unit 422. The voltage conversion unit 422 is used to convert the voltage output by the power supply device 300 into the voltage that can be provided and is required for the switch control board 460 and the control board 420 to drive the startup of the motor 120. The control board 420 is further provided with a drive unit 423 that is electrically connected to the motor 120, thereby realizing the driving of the movement of the motor 120. The control board 420 is further provided with a filtering unit 424 that can filter electrical signals.

[0162] Associated with FIGS. 33, 48 and 49, Base above 210, Base At a position close to 210, a heat dissipation structure for dissipating heat from electronic components such as the motor 120, the power management board 410, and the control board 420 inside the power equipment 10 is further provided. The power equipment 10 is provided with at least two heat dissipation ports, namely the first heat dissipation port 650 and the second heat dissipation Opening 660. The first heat dissipation port 650 and the second heat dissipation port 660 are respectively provided on both the left and right sides of the power equipment 10. The two heat dissipation ports increase the heat dissipation space. The heat dissipation fins 640 are adjacent to the first heat dissipation port 650 and can enhance heat transfer. Thereby, while ensuring the strength of the housing 200, the heat dissipation and heat transfer functional effects of the housing 200 are increased.

[0163] Therefore, air flows into the power equipment 10 from the air inlet 610, dissipates heat from the motor 120, the power management board 410, the control board 420, and the control device 500e inside the housing 200, and then flows out from the first heat dissipation port 650 and the second heat dissipation port 660. In order to accelerate heat dissipation, a thermally conductive silicone rubber may be attached to the motor 120.

[0164] FIGS. 50 to 53 show Base more parameters of 210. Associated with FIGS. 13, 14 and 56, Base The distance along the front - rear direction of 210 is Base the width W1, and the distance along the left - right direction is Base the length L4. Base The ratio of the width W1 to the overall thickness W of the equipment Ratio is 0.3 or more and 0.6 or less. In some embodiments, Base The ratio of the width W1 to the overall thickness W of the equipment Ratio is about 0.4, 0.45 or 0.5. Base The ratio of the length L4 to the overall length L2 of the equipment Ratio is 0.4 or more and 0.7 or less. In some embodiments, Base The ratio of the length L4 to the overall length L2 of the equipment Ratio is about 0.5, 0.55 or 0.6.

[0165] In other words, project the power equipment 10 from top to bottom Base onto the plane where 210 is located, Base the area of 210 and the Base projection area of the power equipment 10 on 210 Ratio is 0.2 or more and 0.5 or less. In some specific embodiments, the Ratio may be 0.3, 0.35 or 0.4. Thereby, the space required for installing the power equipment 10 can be saved as much as possible, and the space utilization rate can be improved.

[0166] As shown in FIG. 51, Base 210 has four Opening 212, a second Opening 213, a third Opening 214 and a fourth Opening 215 respectively, Opening which are.

[0167] Base 210 has at least four openings 216 (see FIG. 51) for attaching the power equipment 10 to the power tool. These four openings 216 are the first opening 212, the second opening 213, the third opening 214 and the fourth opening 215 respectively. Among the four openings 216, the first opening 212 is Base located at the rearmost and leftmost sides of 210, and the second opening 213 is Base located at the rearmost and rightmost sides of 210, the third opening 214 is Base located at the foremost and rightmost sides of 210, and the fourth opening 215 is Base located at the foremost and leftmost sides of 210. The partial enlarged view of the third opening 214 is the first region 2141, and specifically refer to FIG. 52. The partial enlarged view of the second opening 213 is the second region 2131, and specifically refer to FIG. 53.

[0168] The first opening 212 and the third opening 214 present a closed circle, and the inner diameters of the first opening 212 and the third opening 214 are the first diameter d1, and the first diameter d1 is 10 mm or more and 10.1 mm or less.

[0169] The second opening 213 and the fourth opening 215 are in the shape of an open semi - circle. Taking the second opening 213 as an example, the second opening 213 has a semi - circular portion 2181, a first straight portion 2182, and a second straight portion 2183. The first straight portion 2182 and the second straight portion 2183 are substantially parallel, and the distance between the first straight portion 2182 and the second straight portion 2183 is substantially equal to the second diameter d2 of the semi - circular portion 2181, and the second diameter d2 is 10 mm or more and 10.1 mm or less.

[0170] Note that FIG. 51 shows only one arrangement method of the four openings 216. In one embodiment, the first opening 212 and the third opening 214 are in the shape of an open semi - circle, and the second opening 213 and the fourth opening 215 are in the shape of a closed circle. In one embodiment, among the four openings 216, at least one is in the shape of an open semi - circle, that is, there may be one, two, or three openings 216 in the shape of an open semi - circle. In one embodiment, among the four openings 216, at least one is in the shape of a closed circle, that is, there may be one, two, or three openings 216 in the shape of a closed circle.

[0171] To explain in a different way, Base The openings 216 in 210 can be divided into a closed opening 217 and an open opening 218. These openings 216 are for fitting with a mounting material (such as a screw), and thereby, Base 210 is used to attach the power equipment 10 to a power tool. The closed opening 217 may be in a shape such as a circle or a polygon, but the opening is in a completely closed shape. The open opening 218 means that there is no complete boundary formed in the opening.

[0172] In one embodiment, Base Among the multiple openings 216 of 210, there is at least one open opening 218. By doing so, when the user Base attaches 210, it is easier to align the multiple openings 216 with the attachment part of the power tool. In one embodiment, BaseAt least one closed opening 218 exists in a plurality of openings 216 of 210. The installation of the closed opening 218 is advantageous for maintaining the position to be stable after the power equipment 10 and the attachment part of the power tool are combined. More specifically, in one embodiment, Base If there are four openings 216 in 210, these four openings 216 may be two closed openings 217 and two open openings 218, or three closed openings 217 and one open opening 218, or three open openings 218 and one closed opening 217. By varying the number and position of the open openings 218 and the closed openings 217, different assembly difficulties and different assembly stabilities can be achieved.

[0173] Continuing to be associated with FIG. 51, for the open opening 218, that is, the second opening 213 and the fourth opening 215 in the embodiment of FIG. 51, the distance between the closed opening 217 and the open opening 218 is the distance between the center of the closed opening 217 and the center of the semi-circular portion 2181 of the open opening 218. In one embodiment, the distance between the first opening 212 and the second opening 213 and the distance between the third opening 214 and the fourth opening 215 are substantially the same, both being the first distance M1, and the first distance M1 is about 162 mm. The distance between the first opening 212 and the fourth opening 215 and the distance between the second opening 213 and the third opening 214 are substantially the same, both being the second distance M2, and the second distance M2 is about 75 mm. By doing so, the Base 210 mounting size of the power equipment 10 is maintained to be consistent with the mounting size of the conventional engine, and the user does not need to separately mount an intermediate plate, which is easy to mount.

[0174] In another embodiment, the Base 210 mounting size of is distinguished from the mounting size of the conventional engine, Base and the mounting size of the power tool combined with 210 also needs to be changed accordingly. In this case, the first distance M1 is 165 mm or more and 180 mm or less, and the second distance M2 is 80 mm or more and 90 mm or less.

[0175] As shown in FIGS. 54 and 55, the power equipment 10 may have various operating states, and in different operating states, the power equipment 10 has different center-of-gravity positions. When only the first battery pack 310 is attached to the power equipment 10, the center of gravity of the entire equipment is the first center of gravity G1. When only the second battery pack 320 is attached to the power equipment 10, the center of gravity of the entire equipment is the second center of gravity G2. When the first battery pack 310 and the second battery pack 320 are simultaneously attached to the power equipment 10, the center of gravity of the entire equipment is the third center of gravity G3. That is, the power equipment 10 has at least two operable states, and these two operable states have different center-of-gravity positions.

[0176] The power equipment 10 has an operating center of gravity G, and the operating center of gravity G is defined as the center of gravity of the entire equipment when the power equipment 10 can operate normally. The operating center of gravity G is the center of gravity of the entire equipment when the output shaft 110 is driven to rotate by the power supply device 300. The distance Y1 in the vertical direction between the operating center of gravity G and the first axis 111 is 14 cm or less. In one embodiment, the distance Y1 in the vertical direction between the operating center of gravity G and the first axis 111 is 12 cm or less. In one embodiment, the distance Y1 in the vertical direction between the operating center of gravity G and the first axis 111 is 10 cm or less. In one embodiment, the distance Y1 in the vertical direction between the operating center of gravity G and the first axis 111 is 8 cm or less. In some embodiments, the distance Y1 in the vertical direction between the operating center of gravity G and the first axis 111 is about 5 cm, 6 cm or 9 cm. When the operating center of gravity G of the entire equipment is low, it is advantageous for reducing the vibration during the operation of the power equipment 10, Base extending the life of 210, Base and it is also advantageous for preventing the screws at 210 locations from loosening or being damaged.

[0177] The distance X1 in the left-right direction between the operating center of gravity G and the first axis 111 is 10 cm or less. In one embodiment, the distance X1 in the left-right direction between the operating center of gravity G and the first axis 111 is 8 cm or less. In one embodiment, the distance X1 in the left-right direction between the operating center of gravity G and the first axis 111 is 6 cm or less. In some embodiments, the distance X1 in the left-right direction between the operating center of gravity G and the first axis 111 is about 2 cm, 4 cm, or 6 cm. When the operating center of gravity G of the entire equipment is closer to the output shaft 110 in the left-right direction, it is advantageous for maintaining the stability of the operation of the power equipment 10, reducing vibration, and promoting the stability of the output.

[0178] From the above, instead of the conventional engine, for the power equipment 10 that provides power to the power tool, the present application realizes that the operating center of gravity G during the operation of the power equipment 10 is close to the output shaft 110 that outputs power, and the distance between the center of the operating center of gravity G and the center of the output shaft 110 is 14 cm or less in the up-down direction and 10 cm or less in the left-right direction. Note that the description of the distance relationship between the operating center of gravity G and the first axis 111 above is not limited to the structural arrangement shown in FIG. 55, for example, the position, number, tilt angle of the power supply device 300, the control device 500e, and Base is not limited to only the position of 210, etc.

[0179] In connection with what is shown in FIGS. 34 and 56, around the output shaft 110, there is an output shaft mounting portion 160. The output shaft mounting portion 160 is used to fix the output shaft 110 to the input end of the power tool, and to prevent the output shaft 110 from loosening or falling off due to the shaking of the power equipment 10 when the output shaft 110 rotates. There are four mounting ports 165 on the output shaft mounting portion 160, and the four mounting ports 165 form a rectangular shape. As shown in FIG. 56, the four mounting ports 165 are the first mounting port 161, the second mounting port 162, the third mounting port 163, and the fourth mounting port 164 respectively. The distance between the first mounting port 161 and the second mounting port 162 is the third distance M3, and the third distance M3 is about 65.1 mm. The distance between the second mounting port 162 and the third mounting port 163 is equal to the third distance M3. In this way, the four mounting ports 165 form approximately a square. With such a size setting, the size of the output shaft mounting portion 160 becomes equal to that of a conventional engine, and the power equipment 10 can be directly used by replacing the conventional engine.

[0180] In another embodiment, the third distance M3 is 70 mm or more and 80 mm or less. Such a size setting is different from the mounting size of the output shaft of a conventional engine. In this case, the mounting size of the input end of the power tool combined with the power equipment 10 needs to be customized by the user.

[0181] As shown in FIGS. 57 and 58, on the Base 210 of the power equipment 10, a first relay board 260 can be mounted, and through the first relay board 260 BaseAttach 210 to the power tool. The first relay plate 260 can be fastened to the bottom surface 265 of the power equipment 10 by the first screw 261, and the bottom surface 265 may be provided with a plurality of first mounting ports 266 for receiving the first screw 261. The first relay plate 260 has a second mounting port 264 for receiving the second screw 262. In one embodiment, four second mounting ports 264 may be provided, and their arrangement method is consistent with the size parameters disclosed in FIGS. 57 to 56. In another embodiment, the second mounting port 264 may be provided with at least one circular hole and at least one long hole, which facilitates the positioning and mounting of the first relay plate 260.

[0182] Near the output shaft 110, the second relay plate 2 7 0 can be attached, and the second relay plate 270 is attached to the relay plate joint 272 by the third screw 271. There is no restriction on the screw arrangement when assembling the second relay plate 270 and the relay plate joint 272, and the second relay plate 270 may be screwed into the relay plate joint 272 by adopting the form of screw connection. Finally, a third mounting port 165a for connecting the output shaft 110 and a power tool to be compatible is formed on the second relay plate 270. The arrangement method and size of the third mounting port 165a meet the specific parameters disclosed in FIG. 56 in the foregoing text, and will not be repeatedly described here.
