Detailed Implementation

[0008] Before turning to the accompanying drawings, which specifically illustrate certain exemplary embodiments, it should be understood that this disclosure is not limited to the details or methods set forth in the specification or shown in the drawings. It should also be understood that the terminology used herein is for descriptive purposes only and should not be considered limiting.

[0009] In this document, the term "axial" and its variations refer to a direction that extends generally along the axis of symmetry, central axis, or elongation of a particular component or system. For example, an axially extending feature of a component may be a feature that extends generally along a direction parallel to the component's axis of symmetry or elongation. Similarly, the term "radial" and its variations refer to a direction that is generally perpendicular to the corresponding axial direction. For example, a radially extending structure of a component may extend at least partially along a direction perpendicular to the component's longitudinal axis or central axis. The term "circumferential" and its variations refer to a direction that extends generally around the circumference of an object or around the axis of symmetry, central axis, or elongation of a particular component or system.

[0010] Referring generally to the accompanying drawings, the replaceable battery packs described herein can be used in household products, including outdoor power equipment, backup generators, portable site equipment, or other suitable applications. Outdoor power equipment may include lawnmowers, ride-on tractors, snowplows, pressure washers, portable generators, tillers, wood splitters, zero-turn radius lawnmowers, push lawnmowers, wide-width push lawnmowers, ride-on lawnmowers, stand-up lawnmowers, aerators, blowers, edge grinders, lawn rakes, polishers, golf carts, and industrial vehicles (such as forklifts, multi-purpose vehicles, etc.). Outdoor power equipment may use, for example, a power source (e.g., a battery pack) to drive the equipment, such as the rotating blades of a lawnmower, the pump of a pressure washer, the auger of a snowplow, the alternator of a generator, and / or the drivetrain of the outdoor power equipment. Portable site equipment includes portable lighthouses, mobile industrial heaters, and portable light stands.

[0011] As used herein, "household chores product" means any type of equipment, machine, or vehicle that can be used to perform household chores (e.g., outdoor chores, indoor chores, lawn care, etc.). For example, a household chores product may include motors, pumps, actuators, compressors, and / or other devices electrically driven to operate a function of the household chores product to facilitate the performance of household chores. In some embodiments, household chores are tasks performed by a user or autonomously in or near a home, farm, agricultural facility, golf course, building, sidewalk, park, parking lot, forest, field, and / or lawn. In some embodiments, the household chores product transports an operator and performs the household chores. In some embodiments, the household chores product operates autonomously to perform household chores without requiring an operator to be on the household chores product or to physically / manually manipulate the household chores product.

[0012] In general, this disclosure describes various forms of household products or power equipment (e.g., outdoor and / or indoor) that include replaceable battery packs for powering, for example, motors, pumps, lighting assemblies, and / or fans. The household products or power equipment described herein are typically powered by internal combustion engines (ICEs), and retrofitting them to include replaceable battery packs, electric motors, and motor controllers offers several operational advantages. For example, operation no longer requires liquid hydrocarbon fuels and oils, reducing maintenance (e.g., no oil changes) and providing cleaner operation (e.g., no smoke or exhaust). In some cases, cleaner operation enables the power equipment or household product to be used indoors, which was previously impossible due to exhaust emissions. Furthermore, the inclusion of the battery pack eliminates the difficult starting associated with ICE startup and the vibration / noise associated with ICE operation. Additionally, the battery pack and electric motor controller enable instantaneous adjustable variable speed control (e.g., frequency-based AC motors typically operate at a single speed because wall power is a single frequency, while DC power supplied by a battery enables speed control), and the power equipment or household product may not include a clutch. Furthermore, the battery pack can provide instantaneous torque, and the electric motor / fan / pump powered by the battery pack can be tuned for optimal application performance.

[0013] Figures 1 to 7 A household product or power device 10 according to an exemplary embodiment is shown. In the illustrated embodiment, the household product or power device 10 is in the form of a punch 100. The punch 100 is powered by a replaceable battery pack 102, which is housed within a battery holder or mounting bracket 104. The battery mounting bracket 104 is attached to and supported by the body or housing 106 of the punch 100. Specifically, the housing 106 includes a housing surface 108 (e.g., a top or upper surface) that supports the battery mounting bracket 104, a motor mounting bracket 110, and a motor controller 112. The motor mounting bracket 110 supports and connects to an electric motor or household motor 114. In the illustrated embodiment, the motor controller 112 is connected to the housing surface 108. In some embodiments, the motor controller 112 may be connected to the battery mounting bracket 104.

[0014] Battery mounting bracket 104 is connected to battery docking connector 116. Specifically, battery docking connector 116 is connected to the inner surface 118 of battery mounting bracket 104. Battery docking connector 116 is configured to electrically connect to a connector on replaceable battery pack 102. When replaceable battery pack 102 is electrically connected to and secured by battery docking connector 116, replaceable battery pack 102 is configured to selectively supply power to motor controller 112 and electric motor 114 (e.g., in response to an ON / OFF switch being activated to the ON position). Generally, replaceable battery pack 102 supplies power to electric motor 114, and electric motor 114 provides rotational power to a plurality of punching teeth 120, which are actuated to punch holes in the ground through which puncher 100 travels. The design and characteristics of replaceable battery pack 102 and battery docking connector 116 are described in more detail in PCT / US2023 / 033002, owned by the applicant of this application, the entire contents of which are incorporated herein by reference.

[0015] In the illustrated embodiment, the punch 100 defines a central axis 122 extending longitudinally along the punch 100, and the battery mounting bracket 104 is laterally offset from the central axis 122. In other words, no part of the battery mounting bracket 104 intersects the central axis 122. In this way, for example, the battery mounting bracket 104 positions the replaceable battery pack 102 closer to the side of the punch 100, making it more ergonomic for the user to install and remove the replaceable battery pack 102.

[0016] The motor mounting bracket 110 arranges the electric motor 114 at an angle relative to the housing surface 108. Specifically, the motor mounting bracket 110 includes an inclined surface 124 on which the electric motor 114 is supported, and the inclined surface 124 defines an angle A between the inclined surface 124 and the housing surface 108. In some embodiments, angle A is an acute angle. In some embodiments, angle A is between about 5 degrees and about 40 degrees, or between about 10 degrees and about 30 degrees.

[0017] For details, please refer to the following: Figures 8 to 10The battery mounting bracket 104 includes a rear wall 126 having an inner surface 118 and an outer surface 119, a pair of side walls 128, a pair of inclined walls 130, and a bottom wall 132. Generally, when the replaceable battery pack 102 is mounted within the battery mounting bracket 104, the rear wall 126, side walls 128, inclined walls 130, and bottom wall 132 at least partially surround the replaceable battery pack 102. The inclined walls 130 extend laterally opposite sides of the bottom wall 132. Each inclined wall 130 is laterally inclined outward from the bottom wall 132 (e.g., at an acute angle greater than zero degrees and less than ninety degrees) and connects to a corresponding side wall 128. The side walls 128 extend in a direction generally perpendicular to the bottom wall 132. Each side wall 128, inclined wall 130, and bottom wall 132 is connected to the rear wall 126.

[0018] The battery mounting bracket 104 includes one or more mounting holes 134 extending through the rear wall 126 and the bottom wall 132. Generally, the mounting holes 134 formed in the rear wall 126 are used to connect a battery mating connector 116 to the battery mounting bracket 104, while the mounting holes 134 formed in the bottom wall 132 are used to connect the battery mounting bracket 104 to the housing surface 108. The battery mounting bracket 104 includes one or more cooling cutouts or windows 136 formed in the rear wall 126, side walls 128, and / or inclined walls 130. Generally, the cooling cutouts 136 allow airflow through the battery mounting bracket 104 to help cool the replaceable battery pack 102 during operation.

[0019] Figures 11 to 15 A household product or power device 10, categorized as a hole punch 200 according to an exemplary embodiment, is shown. The hole punch 200 is powered by a replaceable battery pack 102. The replaceable battery pack 102 is housed within a battery holder or mounting bracket 202. The battery mounting bracket 202 is attached to and supported by the body or housing 204 of the hole punch 200. Specifically, the housing 204 includes a housing surface 206 (e.g., an inner surface) supporting the battery mounting bracket 202, a motor mounting bracket 208, and a motor controller 210. The motor mounting bracket 208 supports and connects to an electric motor or household motor 212. In the illustrated embodiment, the motor controller 210 is connected to the housing surface 206. In some embodiments, the motor controller 210 may be connected to the battery mounting bracket 202 (e.g., connected to an outer surface 119).

[0020] Battery mounting bracket 202 connects to battery docking connector 116. Specifically, battery docking connector 116 connects to mounting surface 214 of battery mounting bracket 202. When replaceable battery pack 102 is electrically connected to and secured by battery docking connector 116, replaceable battery pack 102 is configured to selectively supply power to motor controller 210 and electric motor 212 (e.g., in response to an ON / OFF switch being activated to the ON position). Overall, replaceable battery pack 102 supplies power to electric motor 212, and electric motor 212 provides rotational power to a plurality of punching teeth 216, which are actuated to punch holes in the ground through which puncher 200 travels.

[0021] In the illustrated embodiment, housing 204 includes a cover or upper wall 218 with a battery cutout 220, through which at least a portion of the battery mounting bracket 202 and replaceable battery pack 102 (when mounted on battery mating connector 116) extends. In the illustrated embodiment, the battery mounting bracket 202 is connected to housing surface 206 and the sidewall 220 of housing 204. The battery mounting bracket 202 is arranged at an angle B relative to housing surface 206 or plane P1, and angle B is not a right angle. In other words, the mounting surface 214 of the battery mounting bracket 202 is not perpendicular to housing surface 206 or plane P1, and angle B can be an obtuse angle greater than about 90 degrees and less than about 135 degrees, or between about 100 degrees and about 120 degrees. Plane P1 intersects both axles along which the wheels of the punch 200 rotate.

[0022] The inclined arrangement of the battery mounting bracket 202 ensures that when the replaceable battery pack 102 is installed in or removed from the battery mounting bracket 202, the replaceable battery pack 102 is arranged at angle B (e.g., at angle B along the central axis extending longitudinally along the centerline of the replaceable battery pack 102 housing). Furthermore, the inclined arrangement of the replaceable battery pack 102 within the battery mounting bracket 202 makes the installation and removal of the replaceable battery pack 102 (e.g., accessing and passing through the battery cutout 220) more ergonomic for the user.

[0023] Figures 16 to 22 A household product or power device 10 as a blower 300 according to an exemplary embodiment is shown. The blower 300 is powered by a replaceable battery pack 102. The replaceable battery pack 102 is housed within a battery holder or mounting bracket 302. The battery mounting bracket 302 is attached to and supported by the body or housing 304 of the blower 300. Specifically, the housing 304 includes a housing surface 306 (e.g., a top or upper surface) supporting the battery mounting bracket 302, a motor mounting bracket 308, and a motor controller 310. The motor mounting bracket 308 supports and connects to an electric motor or household motor 312. In some embodiments, the motor controller 310 (e.g., in...) Figure 18 (Shown in dashed lines) is integrated into the electric motor 312. In some embodiments, the motor controller 310 (e.g., in...) is integrated into the electric motor 312. Figure 18 (shown in dashed line) is connected to and mounted on the outer surface of the battery mounting bracket 302 (e.g., the outer surface 119 of the rear wall 126 opposite to the inner surface 118).

[0024] Generally, the battery mounting bracket 302 may be similar in design and construction to the battery mounting bracket 104, with the same features identified by the same reference numerals unless otherwise described herein or presented in the accompanying drawings. The battery mounting bracket 302 is connected to a battery mating connector 116. Specifically, the battery mating connector 116 is connected to the inner surface 118 of the battery mounting bracket 302. When the replaceable battery pack 102 is electrically connected to and secured by the battery mating connector 116, the replaceable battery pack 102 is configured to selectively supply power to the motor controller 310 and the electric motor 312 (e.g., in response to an ON / OFF switch being activated to the ON position). Generally, the replaceable battery pack 102 supplies power to the electric motor 312, and the electric motor 312 provides rotational power to the fan 316, which rotates to output airflow through outlet 318.

[0025] In the illustrated embodiment, the battery mounting bracket 302 is arranged between the handle assembly 320 and the fan 316, and the electric motor 312 is arranged between the battery mounting bracket 302 and the fan 316.

[0026] Figures 20 to 22 One embodiment of the blower 300 is shown, wherein a motor controller 310 is mounted on and connected to an electric motor 312. Specifically, the motor controller 310 is mounted on the top side of the electric motor 312 (e.g., the side furthest from the ground where the blower 300 travels).

[0027] Figures 23 to 28 A household product or power device 10, as a blower 400, according to an exemplary embodiment, is shown. The blower 400 is powered by a replaceable battery pack 102. The replaceable battery pack 102 is housed within a battery holder or mounting bracket 402. The battery mounting bracket 402 is connected to and supported by a handle assembly 404 of the blower 400. Specifically, the handle assembly 404 includes: an upper portion 406 for a user to grip the handle assembly 404, a lower portion 408 connecting the handle assembly 404 to a housing or body 410 of the blower 400, and an intermediate portion 412 disposed between the upper portion 406 and the lower portion 408. The battery mounting bracket 402 is disposed at the connection between the lower portion 408 and the intermediate portion 412 and extends laterally between rods or bars extending along the intermediate portion 412.

[0028] The housing 410 supports the motor mounting bracket 414 and the motor controller 416. The motor mounting bracket 414 supports and connects to an electric motor or household motor 418. In the illustrated embodiment, the motor controller 416 (e.g., in...) Figure 23 , Figure 24 and Figure 26 (Shown in dashed lines) Connected to and mounted on the outer surface 119 of the battery mounting bracket 402 (e.g., the outer surface 119 of the rear wall 126 opposite the inner surface 118). The motor controller 416 may be encapsulated or covered on the outer surface 119 by a motor controller cover. The motor controller cover may include one or more cover holes, each cover hole aligned with a corresponding mounting hole 134 formed in the rear wall 126 to facilitate attachment of the motor controller cover to the battery mounting bracket 402 (e.g., using fasteners extending through the aligned, paired mounting holes 134 and cover holes 419).

[0029] Generally, the battery mounting bracket 402 may be similar in design and construction to the battery mounting bracket 104, with the same features identified by the same reference numerals unless otherwise described herein or shown in the accompanying drawings. The battery mounting bracket 402 is connected to a battery mating connector 116. Specifically, the battery mating connector 116 is connected to the inner surface 118 of the battery mounting bracket 402. When the replaceable battery pack 102 is electrically connected to and secured by the battery mating connector 116, the replaceable battery pack 102 is configured to selectively supply power to the motor controller 416 and the electric motor 418 (e.g., in response to an ON / OFF switch being activated to the ON position). Generally, the replaceable battery pack 102 supplies power to the electric motor 418, and the electric motor 418 provides rotational power to the fan 420, which rotates to output airflow through outlet 422.

[0030] In the illustrated embodiment, a battery mounting bracket 402 is arranged between the handle assembly 404 and the fan 420, and an electric motor 418 is arranged between the battery mounting bracket 402 and the fan 420. In the illustrated embodiment, the battery mounting bracket 402 connects to the handle assembly 404 such that the battery mounting bracket 402 is arranged at an angle C relative to the plane P2, where angle C is not a right angle. In other words, the inner surface 118 of the battery mounting bracket 402 is not perpendicular to the plane P2, and angle C can be an obtuse angle greater than about 90 degrees and less than about 135 degrees, or between about 100 degrees and about 120 degrees. The plane P2 intersects both axles along which the wheels of the blower 400 rotate.

[0031] The inclined arrangement of the battery mounting bracket 402 ensures that when the replaceable battery pack 102 is installed in or removed from the battery mounting bracket 402, the replaceable battery pack 102 is arranged at angle C (e.g., at angle C along the central axis extending longitudinally along the centerline of the replaceable battery pack 102 housing). Furthermore, the inclined arrangement of the replaceable battery pack 102 within the battery mounting bracket 402 makes the installation and removal of the replaceable battery pack 102 more ergonomic for the user.

[0032] Figures 29 to 31 A household product or power device 10, as a power rake or lawn rake 500, is shown according to an exemplary embodiment.

The battery mounting bracket 602 is integrated into or disposed on a motor housing or housing 604, which is connected to and supported by the body or housing 606 of the edge grinder 600. Specifically, the outer surface 608 (e.g., the top or upper surface) of the motor housing 604 forms the battery mounting bracket 602. A motor controller 610 and an electric motor or household motor 612 are at least partially encapsulated within the motor housing 604. In the illustrated embodiment, the motor controller 610 is connected to an inner surface 614 of the motor housing 604 (e.g., an inner surface arranged opposite the outer surface 608).

[0035] Motor housing 604 includes a bottom wall 616, a pair of side walls 618, a front wall 620, a rear wall 622, and a top wall 624 having an outer surface 608 and an inner surface 614. The bottom wall 616, side walls 618, front wall 620, rear wall 622, and top wall 624 combine to form a housing that encapsulates a motor controller 610 and at least partially encapsulates an electric motor 612 (e.g., a drive shaft may extend out of motor housing 604). In the illustrated embodiment, motor housing 604 is connected to housing 606 at a location generally between a pair of rear wheels 626 and a handlebar assembly 628, with a replaceable battery pack 102 arranged between the rear wheels 626 and the handlebar assembly 628.

[0036] A battery docking connector 116 is attached to the outer surface 608. When the replaceable battery pack 102 is electrically connected to and secured by the battery docking connector 116, the replaceable battery pack 102 is configured to selectively supply power to the motor controller 610 and the electric motor 612 (e.g., in response to an ON / OFF switch being activated to the ON position). Generally, the replaceable battery pack 102 supplies power to the electric motor 612, and the electric motor 612 provides rotational power to the abrasive 630, which rotates to grind the material beneath it.

[0037] In the illustrated embodiment, the outer surface 608 (e.g., the battery mounting bracket 602) is arranged at an angle D relative to the housing surface 636 of the housing 606 (e.g., the surface supporting the motor housing 604). Angle D is not a right angle. In other words, the outer surface 608 is not perpendicular to the housing surface 636, and angle D can be an obtuse angle greater than about 90 degrees and less than about 160 degrees, or between about 100 degrees and about 150 degrees.

[0038] The inclined arrangement of the battery mounting bracket 602 ensures that when the replaceable battery pack 102 is mounted on or removed from the battery mounting bracket 602, the replaceable battery pack 102 is arranged at an angle D (e.g., at an angle D along the central axis extending longitudinally along the centerline of the replaceable battery pack 102 housing). Furthermore, the inclined arrangement of the replaceable battery pack 102 on the battery mounting bracket 602 makes the installation and removal of the replaceable battery pack 102 more ergonomic for the user.

The first sidewall 718, the second sidewall 720, the intermediate wall 726, and the lower wall 727 at least partially encapsulate the electric motor 712.

[0041] The first sidewall 718 includes an inner surface 728 and an outer surface 730. A battery docking connector 116 is connected to the inner surface 728. When the replaceable battery pack 102 is electrically connected to and secured by the battery docking connector 116, the replaceable battery pack 102 is configured to selectively supply power to the motor controller 710 and the electric motor 712 (e.g., in response to an ON / OFF switch being activated to the ON position). Generally, the replaceable battery pack 102 supplies power to the electric motor 712, and the electric motor 712 provides rotational power to a trowel assembly 732 having one or more trowel blades 734, which rotates to smooth the material (e.g., concrete) beneath the trowel assembly 732.

[0042] In the illustrated embodiment, the motor controller 710 (e.g., in...) Figures 62 to 64 and Figures 69 to 70 (Shown in dashed lines) Attached to the outer surface 730 of the first sidewall 718. Specifically, the motor controller 710 is attached to the first sidewall 718 and enclosed within a motor controller housing 735, which is also attached to the first sidewall 718. In this way, for example, the battery housing 702 can serve as a universal housing, helping to support each of the replaceable battery pack 102, the motor controller 710, and the electric motor 712.

[0043] In the illustrated embodiment, the battery housing 702 arranges the replaceable battery pack 102 at an angle relative to the mounting plate 704 and the axis of rotation 736 (e.g., the axis around which the blade 734 rotates) defined by the polishing assembly 732. In the illustrated embodiment, the bottom wall 722 is arranged at an angle relative to the upper surface 706 of the mounting plate 704 such that an axis 738 perpendicular to the bottom wall 722 and extending along the centerline of the replaceable battery pack 102 defines an angle E between this axis and the upper surface 706. In the illustrated embodiment, angle E is not a right angle, and the bottom wall 722 is not perpendicular to the upper surface 706. In some embodiments, angle E may be an acute angle greater than about 0 degrees and less than about 90 degrees, or greater than about 10 degrees and less than about 80 degrees, or between about 20 degrees and about 70 degrees. The tilting orientation of the bottom wall 722 also defines an angle F between the axis of rotation 736 and the axis 738. In some embodiments, angle F is approximately equal to 90 degrees minus angle E. In some implementations, angle F can be an acute angle greater than about 0 degrees and less than about 90 degrees, or greater than about 10 degrees and less than about 80 degrees, or between about 20 degrees and about 70 degrees.

[0044] The inclined arrangement of the bottom wall 722 allows the replaceable battery pack 102 to be arranged at angle E or angle F when it is installed in or removed from the battery housing 702. Furthermore, the inclined arrangement of the replaceable battery pack 102 within the battery housing 702 makes the installation and removal of the replaceable battery pack 102 more ergonomic for the user.

[0045] Figures 48 to 51A household product or power device 10, as a power trowel 800 (e.g., a push-type power trowel), is shown according to an exemplary embodiment. Generally, the power trowel 800 is similar to the power trowel 700, with identical components identified using the same reference numerals unless otherwise described herein or shown in the accompanying drawings. The power trowel 800 is a different model from the power trowel 700, but uses a battery housing 702 to connect a replaceable battery pack 102, a motor controller 710, and an electric motor 712 to the power trowel 800. It should be understood that the type of motor controller or the rated power of the electric motor may vary depending on the power trowel model, but the design and characteristics of the battery housing 702 remain unchanged. In this way, for example, the battery housing 702 can serve as a retrofit kit for mounting electrical components (i.e., the replaceable battery pack 102, the motor controller 710, and the electric motor 712) to a power device previously or normally powered by an ICE.

[0046] Figure 52 A household product or power device 10, as a power trowel 900 (e.g., a push-type power trowel), according to an exemplary embodiment, is shown. Generally, the power trowel 900 is similar to the power trowel 700, with identical components identified by the same reference numerals unless otherwise described herein or shown in the accompanying drawings. The power trowel 900 is a different model from the power trowel 700, but uses a battery housing 702 to connect a replaceable battery pack 102, a motor controller 710, and an electric motor 712 to the power trowel 900.

[0047] Figures 53 to 55 A household product or power device 10 as a lighthouse 1000 according to an exemplary embodiment is shown. The lighthouse 1000 is powered by a replaceable battery pack 102 (e.g., one or more replaceable battery packs 102). The replaceable battery pack 102 is housed within a battery holder or housing 1002. The battery housing 1002 is supported on and connected to a base 1004 of the lighthouse 1000. Specifically, the battery housing 1002 is connected to a mounting surface 1006 (e.g., top or upper surface) of the base 1004. In some embodiments, a motor controller 1008 (e.g., in…) is also included. Figure 54 (shown in dashed line) Connected to battery housing 1002.

[0048] In some embodiments, the lighthouse 1000 includes one or more battery housings 1002 supported on a base 1004, each battery housing being configured to receive a replaceable battery pack 102. The battery housing 1002 includes a first sidewall 1010, a second sidewall 1012, a support 1014, and a bottom wall 1016. The first sidewall 1010, second sidewall 1012, support 1014, and bottom wall 1016 combine to form a receiving cavity for the replaceable battery pack 102. The support 1014 extends from the first sidewall 1010 to the second sidewall 1012 and includes one or more slits that facilitate increased airflow through the replaceable battery pack 102.

[0049] The first sidewall 1010 includes an inner surface 1018 and an outer surface 1020. A battery docking connector 116 is connected to the inner surface 1018. In some embodiments, a motor controller 1008 is connected to the outer surface 1020. When the replaceable battery pack 102 is electrically connected to and secured by the battery docking connector 116, the replaceable battery pack 102 is configured to selectively supply power to the lighting assembly 1022 of the lighthouse 1000. In some embodiments, the lighthouse 1000 may include an electric motor or electric actuator powered by the replaceable battery pack 102 and used to raise and lower the telescopic mast 1024 of the lighthouse 1000.

[0050] In the illustrated embodiment, the battery housing 1002 arranges the replaceable battery pack 102 at an angle relative to the mounting surface 1006. In the illustrated embodiment, the bottom wall 1016 is arranged at an angle relative to the mounting surface 1006 of the base 1004, such that an axis 1026 perpendicular to the bottom wall 1016 and extending along the centerline of the replaceable battery pack 102 defines an angle G between this axis and the mounting surface 1006. In the illustrated embodiment, angle G is not a right angle, and the bottom wall 1016 is not perpendicular to the mounting surface 1006. In some embodiments, angle G may be an acute angle greater than about 0 degrees and less than about 90 degrees, or greater than about 10 degrees and less than about 80 degrees, or between about 20 degrees and about 70 degrees.

[0051] The inclined arrangement of the battery housing 1002 ensures that the replaceable battery pack 102 is positioned at angle G when it is installed on or removed from the battery housing 1002. Furthermore, this inclined arrangement of the replaceable battery pack 102 on the battery housing 1002 makes installation and removal of the replaceable battery pack 102 more ergonomic for the user.

The right side wall 1116 and left side wall 1118 are each connected to and extend between the rear wall 1120 and the front wall 1122, and each of the right side wall 1116, left side wall 1118, and front wall 1122 includes one or more slits that facilitate increased airflow through the replaceable battery pack 102.

[0054] The rear wall 1120 includes an inner surface 1124 and an outer surface 1126. A battery docking connector 116 is connected to the inner surface 1124. In some embodiments, a motor controller 1114 is connected to the outer surface 1126. When the replaceable battery pack 102 is electrically connected to and secured by the battery docking connector 116, the replaceable battery pack 102 is configured to selectively supply power to the grinding assembly 1128 of the floor grinder 1100.

[0055] Figures 59 to 63A household product or power device 10, purportedly a concrete grinder 1200, is shown according to an exemplary embodiment.

In the illustrated embodiment, the motor controller 1226 is connected to and mounted on the outer surface 1216 of the battery mounting bracket 1202.

[0058] In the illustrated embodiment, the outer surface 1216 (e.g., battery mounting bracket 1202) is arranged at an angle H relative to the mounting surface 1220 of the housing 1210. The angle H is not a right angle. In other words, the outer surface 1216 is not perpendicular to the mounting surface 1220, and the angle H can be an obtuse angle greater than about 90 degrees and less than about 160 degrees, or between about 100 degrees and about 150 degrees.

[0059] The inclined arrangement of the battery mounting bracket 1202 ensures that the replaceable battery pack 102 is arranged at an angle H (e.g., at an angle H along the central axis extending longitudinally along the centerline of the housing of the replaceable battery pack 102) when it is mounted on or removed from the battery mounting bracket 1202.
