[0019] Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

[0020] The use herein of the term “axial” and variations thereof refers to a direction that extends generally along an axis of symmetry, a central axis, or an elongate direction of a particular component or system. For example, axially extending features of a component may be features that extend generally along a direction that is parallel to an axis of symmetry or an elongate direction of that component. Similarly, the use herein of the term “radial” and variations thereof refers to directions that are generally perpendicular to a corresponding axial direction. For example, a radially extending structure of a component may generally extend at least partly along a direction that is perpendicular to a longitudinal or central axis of that component. The use herein of the term “circumferential” and variations thereof refers to a direction that extends generally around a circumference or periphery of an object, around an axis of symmetry, around a central axis, or around an elongate direction of a particular component or system.

[0021] Conventional industrial vacuums are typically powered by utility power (e.g., wall power) and the utility power is supplied to the industrial vacuum via a cable or power chord that connects between a wall outlet and the industrial vacuum. The requirement to supply conventional industrial vacuums with utility power restricts operation of the conventional industrial vacuums to locations that have available utility power, and limits how far the vacuum is able to operate from the wall outlet (e.g., limited by cable / power cord length). In addition, a user must continually manage the cable / power cord while operating the vacuum, which lowers operational efficiency.-3- 4900-0557-5560Atty. Dkt. No.: 016831-1992

[0022] The present disclosure provides a battery-powered industrial vacuum that includes a swappable battery pack, which removes the need to power the vacuum with utility power. Accordingly, a user may operate the vacuum in any location without a connection to a power cord.

[0023] FIGS. 1-5 show an exemplary embodiment of an industrial vacuum 100 that is fully electric and battery powered by a battery power system 101. The industrial vacuum 100 includes a chassis or frame 102, a pair of vacuum motors 104 coupled to the frame 102, a dock assembly 106 coupled to the frame 102, and a plurality of wheels 108. In some embodiments, the frame 102 is fabricated from a metal material. The frame 102 is coupled to and supported on the plurality of wheels 108, which enables the industrial vacuum 100 to travel, for example, by a user grasping a handle 109 coupled to the frame 102 and pushing the industrial vacuum 100 in a travel direction. The frame 102 includes a top cap or cover 110 that is coupled to and extends over a top side of the frame 102.

[0024] In the illustrated embodiment, the industrial vacuum 100 includes two of the vacuum motors 104 that are coupled to and supported on the cover 110. In some embodiments, the industrial vacuum 100 may include more (e.g., three or more) or less (e.g., one) of the vacuum motors 104. In some embodiments, the vacuum motors 104 may be DC motors that are powered by DC power. In general, when the vacuum motors 104 receive electrical power (e.g., DC power), the vacuum motors 104 rotate a fan or impeller and generate a negative pressure in a vacuum chamber within the frame 102, which generates suction and air flow into the vacuum chamber through a vacuum inlet 112. The vacuum inlet 112 extends outwardly through the frame 102 and is configured to connect to a hose or tube.

[0025] In general, the dock assembly 106 is configured to selectively and removably couple to, and electrically connect to, a swappable battery pack 114. The dock assembly 106 includes a battery dock 116 and a mounting bracket 118. The swappable battery pack 114 includes a battery connector that is configured to mate with a dock connector 120 on the battery dock 116, upon the swappable battery pack 114 being installed on the dock assembly 106. The swappable battery pack 114 and the battery dock 116 are further described in International Patent Application No. PCT / US2023 / 033002, filed on September 18, 2023, which is incorporated herein by reference in its entirety. A wiring assembly 121 (e.g., a wiring harness) is connected to the battery dock 116-4- 4900-0557-5560Atty. Dkt. No.: 016831-1992and is configured to provide electrical power and / or communication between the swappable battery pack 114 and the vacuum motors 104. Accordingly, when the swappable battery pack 114 is installed on the dock assembly 106 and connected to the dock connector 120, the vacuum motors 104 may be powered by the swappable battery pack 114 and generate suction at the vacuum inlet 112. In some embodiments, the battery power system 101 includes the dock assembly 106, the swappable battery pack 114, and the wiring assembly 121.

[0026] In the illustrated embodiment, the dock assembly 106 is coupled to a side (e.g., a lateral or left side) of the frame 102. In some embodiments, the dock assembly 106 may be coupled to another side of the frame 102 (e.g., a rear side under the handle). In general, the mounting bracket 118 facilitates coupling the battery dock 116, and thereby the swappable battery pack 114, to the frame 102. The mounting bracket 118 includes a dock-mounting surface 122, a pair of sidewalls 124, and one or more bracket flanges 126 (see, e.g., FIG. 3). The battery dock 116 is coupled to the dock-mounting surface 122 via one or more fastening elements (e.g., screws, bolts, etc.), so that the battery dock 116 is arranged laterally between the sidewalls 124 (see, e.g., FIG. 2). The sidewalls 124 extend perpendicularly outwardly from laterally opposing sides of the dockmounting surface 122.

[0027] In general, the one or more bracket flanges 126 of the mounting bracket 118 each couple to the frame 102 to secure the mounting bracket 118, and thereby the battery dock 116, to the frame 102. In the illustrated embodiment, the mounting bracket 118 includes a first mounting flange 128, a second mounting flange 130, and a third mounting flange 132. In some embodiments, the mounting bracket 118 may include more or less than three of the bracket flanges 126. The first mounting flange 128 and the second mounting flange 130 extend outwardly (e.g., downwardly from the perspective of FIGS. 1-3) from a bottom edge of the dock-mounting surface 122, in a direction that is generally parallel to the dock-mounting surface 122. The first mounting flange 128 and the second mounting flange 130 both engage an outer surface 134 of the frame 102, and one or more fastening elements (e.g., a screw, a bolt, etc.) extends through each of the first mounting flange 128 and the second mounting flange 130 and into the outer surface 134 to fasten the mounting bracket 118 to the frame 102. In some embodiments, the mounting bracket 118 may include one or the first mounting flange 128 or the second mounting flange 130.-5- 4900-0557-5560Atty. Dkt. No.: 016831-1992

[0028] The third mounting flange 132 extends outwardly from the bottom edge of the dockmounting surface 122, in a direction that is generally perpendicular to the dock-mounting surface 122 (e.g., in an opposite direction that the sidewalls 124 extend from the dock-mounting surface 122). The third mounting flange 132 engages a flange surface 136 of the frame 102, and one or more fastening elements (e.g., a screw, a blot, etc.) extends through the third mounting flange 132 and into the flange surface 136 to fasten the mounting bracket 118 to the frame 102.

[0029] In some embodiments, the third mounting flange 132 spaces the mounting bracket 118 from a side of the frame 102, so that a gap is arranged between the mounting bracket 118 and the frame 102 (see, e.g., FIG. 4), which aids in providing space to route the wiring assembly 121 from the dock assembly 106 to the vacuum motors 104, and the other components of the industrial vacuum 100 connected to the wiring assembly 121. For example, with reference to FIGS. 2 and 4-8, the wiring assembly 121 is in electrically coupled to the dock connector 120 of the battery dock 116 and is configured to supply electrical power and / or electrical communication (e.g., CAN communication) from the swappable battery pack 114 to the vacuum motors 104, and various other components of the industrial vacuum 100. Specifically, the wiring assembly 121 includes a first cable 138 that provides an electrical connection between high power terminals 140 (positive and negative terminals) of the dock connector 120, which electrically connect to the high power terminals of the swappable battery pack 114, when the swappable battery pack 114 is connected to the dock connector 120, and a power connector 142. From the power connector 142, the wiring assembly 121 includes a second cable 144 that is connected between the power connector 142 and a junction conduit box 146 (see, e.g., FIG. 7).

[0030] In some embodiments, the power connector 142 is a plug-in connector that includes a first connector body 148 that is connected to the first cable 138, and a second connector body 150 that is connected to the second cable 144 (see, e.g., FIG. 5). When the first connector body 148 is plugged into the second connector body 150, the power connector 142 provides and electrical connection between the first cable 138 and the second cable 144. In some embodiments, the first connector body 148 may be disconnected from the second connector body 150 to enable the dock assembly 106 to be removed from the frame 102, without requiring removal of the portions of the wiring assembly 121 that are downstream of the second cable 144. In other words, with the first-6- 4900-0557-5560Atty. Dkt. No.: 016831-1992connector body 148 disconnected from the second connector body 150, the first cable 138 and the dock assembly 106 may be removed from the frame 102 (e.g., to provide access to a filter for replacement or cleaning) and the second cable 144 (and the remaining portions of the wiring assembly 121) remains attached to the frame 102. Once the dock assembly 106 is reinstalled on the frame 102, the first connector body 148 can be reconnected to the second connector body 150, and the industrial vacuum 100 may be operated once again. Accordingly, the wiring assembly 121 only requires a single connector (i.e., the power connector 142 to be disconnected / connected) to facilitate removal of the dock assembly 106 for maintenance and cleaning.

[0031] The second cable 144 is routed from the power connector 142 to a cable gland 152 that is coupled to the cover 110 of the frame 102 (see, e.g., FIG. 8). The cable gland 152 is coupled to and extends through the cover 110, and includes an internal conduit or passageway through which the second cable 144 is routed into an internal chamber or volume within the frame 102. The junction conduit box 146 may be arranged within the internal chamber within the frame 102. After the junction conduit box 146, the wiring assembly 121 includes a first motor cable 154 that extends from the junction conduit box 146 and connects to one of the vacuum motors 104 (e.g., a first vacuum motor), and a second motor cable 156 that extends from the junction conduit box 146 and connects to another one of the vacuum motors 104 (e.g., a second vacuum motor). Accordingly, the wiring assembly 121, including the first cable 138, the second cable 144, the first motor cable 154, and the second motor cable 156, routes electrical power from the swappable battery pack 114 and the battery dock 116 to the vacuum motors 104.

[0032] As shown in FIGS. 7 and 8, the industrial vacuum 100 includes a battery power switch 158 that is configured to enable or disable the swappable battery pack 114 from outputting electrical power to the battery dock 116, and thereby to the wiring assembly 121 and the vacuum motors 104. In some embodiments, the battery power switch 158 is a double-pole, single throw switch. In the illustrated embodiment, the battery power switch 158 is mounted to a switch plate 160 that is coupled to the dock assembly 106. Specifically, the switch plate 160 extends between a rear surface 162 of the mounting bracket 118 (e.g., a surface opposite to the dock-mounting surface 122) and the frame 102 (see, e.g., FIG. 8). Each of the vacuum motors 104 includes a motor switch 164 (e.g., a first motor switch and a second motor switch) that is configured to enable-7- 4900-0557-5560Atty. Dkt. No.: 016831-1992or disable the respective one of the vacuum motors 104 from receiving electrical power. During operation, when the swappable battery pack 114 is installed on the battery dock 116 and connected to the dock connector 120, a user may flip the battery power switch 158 to a position where electrical power is provided from the high power terminals 140 to the first cable 138, through the power connector 142 and the second cable 144, and to the junction conduit box 146. Once a user switches the motor switch 164 on each of the vacuum motors 104, electrical power is provided from the swappable battery pack 114 to each of the vacuum motors 104, and the vacuum motors 104 operate to generate suction at the vacuum inlet 112. The industrial vacuum 100 may be operated, without the restrictions of requiring utility power and a power cord, until the job is complete or the swappable battery pack 114 reaches a low state of charge threshold and requires recharging. If the swappable battery pack 114 requires recharging, a user may manually disconnect the swappable battery pack 114 from the battery dock 116 and recharge the swappable battery pack 114, and / or replace the swappable battery pack 114 with another swappable battery pack 114 that is charged.

[0033] With reference to FIGS. 1-4 and 7, the wiring assembly 121 includes a grounding cable or wire 166 that extends between a grounding pin 168 on the frame 102 and the power connector 142. A grounding strap 170 is electrically connected to the grounding pin 168 and drags on a floor on which the industrial vacuum 100 travels to electrically ground the industrial vacuum 100 and prevent static buildup. The electrical ground provided by the grounding strap 170 is electrically connected to the frame 102 via the grounding pin 168, and to a motor housing on each of the vacuum motors 104 (see, e.g., FIG. 7).

[0034] As described herein, in an exemplary embodiment, the vacuum motors 104 directly receive electrical power (e.g., about 48V DC power) from the swappable battery pack 114. In some embodiments, as shown in FIG. 9, the electrical power from the swappable battery pack 114 may be supplied to a motor controller 172 and the motor controller 172 may provide electrical power (e.g., DC power or AC power) to the vacuum motors 104 and control operation thereof. In some embodiments, the vacuum motors 104 may be configured to operate on AC power, and the industrial vacuum 100 may include power electronics (e.g., a converter, an inverter, the motor controller 172, etc.) that converts the DC power from the swappable battery pack 114 to AC power.-8- 4900-0557-5560Atty. Dkt. No.: 016831-1992

[0035] According to an exemplary embodiment, the industrial vacuum 100 may include more than one of the swappable battery packs 114. FIGS. 10 and 11 show the industrial vacuum 100 including two of the swappable battery packs 114, with each of the swappable battery packs 114 being coupled to a side of the frame 102 by a dock assembly 106 (e.g., a first dock assembly with a first dock connector and a first mounting bracket, and a second dock assembly with a second dock connector and a second mounting bracket). The swappable battery packs 114 may be connected in parallel and provide electrical power to the vacuum motors 104. With the swappable battery pack 114 connected in parallel, the runtime (e.g., operational time without requiring recharge) of the industrial vacuum 100 may be extended. In some embodiments, with the inclusion of two of the swappable battery packs 114, the wiring assembly 121 may further include communication cables (e.g., CAN wires / cables, etc.) that provide communication between a battery management system (BMS) within each of the swappable battery packs 114 and a controller (e.g., a processor and at least one memory) that controls operation of the swappable battery packs 114 and / or the vacuum motors 104. Additionally, the industrial vacuum 100 may include busbars that receive electrical power from the parallel connection between the swappable battery packs 114.

[0036] As utilized herein with respect to numerical ranges, the terms “approximately,” “about,” “substantially,” and similar terms generally mean + / - 10% of the disclosed values. When the terms “approximately,” “about,” “substantially,” and similar terms are applied to a structural feature (e.g., to describe its shape, size, orientation, direction, etc.), these terms are meant to cover minor variations in structure that may result from, for example, the manufacturing or assembly process and are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains.
