Where a unit "controller," "processor," "central processing unit," "CPU," or "MCU" is used to perform a particular function, unless otherwise specified, the function may be performed by a single unit or a plurality of units.
[0091] In this application, the terms "device", "module" or "unit" can be implemented in the form of hardware or software to achieve specific functions.
[0092] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).
[0093] The present application provides a power tool, which may be a machine with self-propelled function such as a lawn mower, a snow blower or a wheelbarrow. As an embodiment, referring to Figures 1 to 6, the power tool is a lawn mower 100. The lawn mower 100 includes a main unit 110, a handle assembly 120 and a passenger assembly 130. The main unit 110 includes a functional assembly, a main unit housing 111 and a travel assembly 112. The main unit housing 111 supports the functional assembly, and the travel assembly 112 is connected to the main unit housing 111. The handle assembly 120 is connected to the main unit 110, and the passenger assembly 130 is connected to the main unit 110. The passenger assembly 130 includes a passenger part 131 for supporting the user. When the entire machine is moving, the user can be located in the passenger part 131, and the lawn mower 100 drives the user forward without the user having to exert any effort.
[0094] In the case of a lawn mower 100, the functional component is a blade assembly for mowing grass, which is driven by a drive motor to rotate and achieve the cutting function. The lawn mower 100 of the present application is an improvement on a push-type lawn mower. By adding a passenger assembly 130, the user no longer needs to walk with the lawn mower 100. Instead, the user stands or sits on the passenger assembly 131, and the lawn mower 100 drives the user forward.
[0095] The manned assembly 130 can be connected to the rear of the host 110 to facilitate the user to hold the handle assembly 120. In some embodiments, the manned assembly 130 can also be connected to the left or right side of the host 110, and the handle assembly 120 can also be detachable.
[0096] In some embodiments, the manned portion 131 includes a seat on which the user can sit to increase comfort. In some embodiments, the manned portion 131 includes a pedal 1311 on which the user can stand to save space.
[0097] The power tool has a hand-push mode and a manned mode. When the power tool is in the hand-push mode, the manned component 130 is in a first state relative to the main unit 110. When the power tool is in the manned mode, the manned component 130 is in a second state relative to the main unit 110. In the hand-push mode, the user can stand on the ground and walk with the power tool holding the handle component 120. At this time, the manned component 130 is in the first state relative to the main unit 110 and will not interfere with the user's walking. In the manned mode, the manned component 130 is in the second state relative to the main unit 110, and the user can be located in the manned part 131, and the power tool drives the user to walk without the user having to exert any effort, saving time and effort. One difference between the hand-push mode and the manned mode is that in the hand-push mode, the user's feet need to touch the ground to walk, while in the manned mode, the user's feet do not need to touch the ground to walk.
[0098] In some embodiments, the manned portion 131 is foldable or rotatable to switch between a first state and a second state. As a feasible embodiment, the manned portion 131 includes a pedal 1311, which is foldable or rotatable relative to the main unit 110. Specifically, one end of the pedal 1311 is rotatably connected to the main unit housing 111, and the pedal 1311 can switch between a horizontal state and a vertical state. The pedal 1311 and the main unit housing 111 can be rotatably connected via a hinge assembly. When the pedal 1311 is in a horizontal state, the manned component 130 is in a second state relative to the main unit 110, and the user can stand on the pedal 1311. When the pedal 1311 is in a vertical state, the manned component 130 is in a first state relative to the main unit 110, and the user can stand on the ground and walk with the power tool. Since the pedal 1311 is in a vertical state, space is saved.
[0099] In some embodiments, the manned assembly 130 is detachable relative to the main unit 110. In the push mode, the manned assembly 130 is disassembled. By disassembling the manned assembly 130, space is saved and the storage of the manned assembly 130 is facilitated. In the manned mode, the manned assembly 130 is mounted to the main unit 110. The manned assembly 130 and the main unit 110 can be connected by pins, hooks, plugs and other components that are easy to disassemble. In some embodiments, when the power tool is in the push mode, the manned assembly 130 can also be mounted to the main unit 110. In some embodiments, when the power tool is in the push mode, the user can also hold the handle assembly 120 or other handles for the user to hold on to.
[0100] In some embodiments, the passenger assembly 130 has no power of its own, and the power for the lawn mower 100 to move comes from the travel assembly 112. The travel assembly 112 includes travel wheels 1121 and a travel motor. When in use, the travel motor drives the travel wheels 1121 to move, thereby driving the entire machine to move.
[0101] When the power tool is a lawn mower 100, the running wheels 1121 of the lawn mower 100 include a front wheel and a rear wheel, wherein the front wheel is a universal wheel for easy steering. The running motor is used to drive the rear wheel to rotate.
[0102] The power tool also includes a control device 100a for controlling the travel assembly 112. When the power tool is in a push mode, the passenger assembly 130 is in a first state relative to the main body 110, and the control device 100a receives user input from the handle assembly 120 to control the travel assembly 112. When the power tool is in a passenger mode, the passenger assembly 130 is in a second state relative to the main body 110, and the control device 100a receives at least user input from the passenger assembly 130 to control the travel assembly 112.
[0103] In push mode, the user can stand on the ground, holding the handle assembly 120 and walking along with the power tool. At this time, the passenger assembly 130 is in a first state relative to the main body 110 and does not interfere with the user's walking. The control device 100a receives the user's input to the handle assembly 120 to control the walking assembly 112. In passenger mode, the passenger assembly 130 is in a second state relative to the main body 110. The user can be positioned in the passenger section 131 and be driven by the power tool to walk. The control device 100a at least receives the user's input to the passenger assembly 130 to control the walking assembly 112.
[0104] In the manned mode, since the user is located in the manned part 131, it is convenient to operate the manned component 130. At this time, the user does not need to hold the handle component 120, so the control device 100a at least receives the user's input to the manned component 130 to control the walking component 112, which is convenient for user operation.
[0105] When the power tool is in passenger mode, the control device 100a is configured to receive user input on the handle assembly 120 to control the travel assembly 112. In passenger mode, the user is located in the passenger section 131 and can operate either the passenger assembly 130 or the handle assembly 120, providing the user with more options and improving the user experience.
[0106] In the push mode, the control device 100a is in a first control state when receiving user input from the handle assembly 120 to control the travel assembly 112. In the passenger mode, the control device 100a is in a second control state when receiving at least user input from the passenger assembly 130 to control the travel assembly 112. The control device 100a automatically identifies the passenger mode and the push mode to switch between the first control state and the second control state. The automatic identification of the passenger mode and the push mode by the control device 100a facilitates timely switching between the first control state and the second control state to meet user needs.
[0107] In some embodiments, the control device 100a includes a selection switch 150. The user switches between the manned mode and the push mode by operating the selection switch 150. The selection switch 150 has a pressed state and a raised state. In the pressed state, the power tool is in the manned mode, and in the raised state, the power tool is in the push mode.
[0108] The control device 100a is configured to control the walking component 112 to enter a forward mode, a backward mode, or a steering mode. In some embodiments, the control device 100a includes a mode button 140. By operating the mode button 140, the walking component 112 is configured to switch between a forward mode, a backward mode, and a steering mode. The mode button 140 can be provided on both the handle assembly 120 and the manned assembly 130 to facilitate the user to operate according to their own needs.

[0110] In some embodiments, the passenger assembly 130 includes a pedal 1311, which includes a pedal area 1311a. The pedal area 1311a is provided with a pressure sensor 1311b, and the power tool moves forward or backward according to the pressure value of the pressure sensor 1311b. As a feasible embodiment, the pedal area 1311a is divided into a front pedal area 1311a and a rear pedal area 1311a. When the pressure value of the front pedal area 1311a is greater than a first set value and the pressure of the rear pedal area 1311a is less than a second set value, the power tool moves forward. When the pressure value of the front pedal area 1311a is less than the second set value and the pressure of the rear pedal area 1311a is greater than the first set value, the power tool moves backward. The first set value is greater than the second set value.
[0111] Furthermore, the power tool can adjust its speed based on the pressure value of pressure sensor 1311b. In one achievable embodiment, the pedaling area 1311a is divided into a front pedaling area 1311a and a rear pedaling area 1311a. When the pressure value in the front pedaling area 1311a is greater than a first set value and less than a third set value, the power tool advances at a first speed. When the pressure value in the front pedaling area 1311a is greater than the third set value, the power tool advances at a second speed.
[0112] In some embodiments, the pedaling area 1311a includes at least a left pedaling area 1311a and a right pedaling area 1311a, and the power tool turns according to the pressure difference between the left pedaling area 1311a and the right pedaling area 1311a.

During the forward movement of the power tool, when the pressure value of the front pedaling area 1311a of the left pedaling area 1311a is greater than the pressure value of the front pedaling area 1311a of the right pedaling area 1311a, and the difference between the two is greater than or equal to a first set difference, the power tool turns left.
[0113] In some embodiments, the passenger assembly 130 includes a clamping rod 1312 connected to a torque sensor 1312a. The power tool steers based on the torque measured by the torque sensor 1312a. The clamping rod 1312 can be clamped between the legs and / or the feet. In one achievable embodiment, when the clamping rod 1312 is twisted to the left and the torque value is greater than a first set torque, the power tool steers to the left.
[0114] The pressure sensor 1311 b and the torque sensor 1312 a are both electrically connected to the control device 100 a , and the control device 100 a controls the travel component 112 by receiving pressure values and torque values.
[0115] In some embodiments, the passenger module 130 includes passenger wheels 132 , which support the passenger unit 131 . When the entire machine moves, the passenger wheels 132 are driven to move, thereby driving the passenger unit 131 to move.
[0116] In some embodiments, the passenger assembly 130 is powered, and the power for the lawn mower 100 to move can come from the travel assembly 112 or the passenger assembly 130. Specifically, the passenger assembly 130 includes passenger wheels 132 and a passenger motor 135. The passenger wheels 132 support the passenger section 131, and the passenger motor 135 is connected to the passenger wheels 132 to drive the passenger wheels 132. The passenger motor 135 drives the passenger wheels 132 to move, thereby driving the entire machine.
[0117] In some embodiments, the passenger travel motor 135 is a hub motor.
[0118] In some embodiments, two passenger travel wheels 132 are provided, spaced apart in the left-right direction, and a passenger travel motor 135 is provided for each passenger travel wheel 132. Steering can be controlled based on the speed difference between the two passenger travel motors 135. In one achievable embodiment, when the speed of the left passenger travel motor 135 is greater than the speed of the right passenger travel motor 135, and the speed difference between the two is greater than or equal to a first speed value, the power tool turns right.
[0119] When the passenger travel motor 135 is turned on to drive the passenger travel wheels 132, the travel motor of the travel assembly 112 is turned off to prevent interference. In some embodiments, the passenger travel motor 135 and the travel motor of the travel assembly 112 can be turned on at the same time, and a differential clutch transmission is used between the two to prevent interference.
[0120] The main unit 110 also includes a battery pack 110a, which is detachably connected to the main unit housing 111 to power at least the travel unit 112. The battery pack 110a is removable for easy charging. The battery pack 110a powers the travel motor of the travel unit 112, which drives the travel wheels 1121 of the travel unit 112.
[0121] In some embodiments, the battery pack 110a supplies power to the passenger travel motor 135. The passenger travel motor 135 and the travel assembly 112 share the battery pack 110a, reducing the number of components.
[0122] Typically, the battery pack 110a is housed within the main body housing 111. In the front-to-back direction, the distance between the battery pack 110a and the passenger module 130 is greater than or equal to 200 mm and less than or equal to 500 mm.

[0123] The main unit 110 includes a first electrical interface 113, and the passenger assembly 130 includes a second electrical interface 134 that is detachably connected to the first electrical interface 113. After the first electrical interface 113 and the second electrical interface 134 are connected, the battery pack 110a can power the passenger travel motor 135 and the pressure sensor 1311b on the passenger assembly 130.
[0124] When the first electrical interface 113 is connected to the second electrical interface 134 , the power tool is in the passenger mode. The control device 100 a can identify the push mode and the passenger mode by detecting the conductive state of the first electrical interface 113 and the second electrical interface 134 .
[0125] In other embodiments, the passenger module 130 includes a first power source 130a independent of the battery pack 110a. The first power source 130a powers the passenger travel motor 135. When the battery pack 110a, which is powering the travel module 112, runs out of power, the first power source 130a can be used to power the passenger travel motor 135 to drive the entire vehicle, thereby extending the vehicle's battery life.
[0126] The passenger assembly 130 includes a control assembly configured to control the forward, reverse, or steering movement of the passenger wheels 132.

The main body 110 includes a first electrical interface 113, and the passenger assembly 130 includes a second electrical interface 134 that is detachably connected to the first electrical interface 113. When the passenger assembly 130 is separated from the main body 110, the first electrical interface 113 and the second electrical interface 134 are disconnected. When the passenger assembly 130 is connected to the main body 110, the first electrical interface 113 and the second electrical interface 134 are electrically connected.
[0129] In some embodiments, the first electrical interface 113 is disposed at the rear end of the host 110 . The passenger module 130 is typically disposed at the rear end of the host 110 , and the second electrical interface 134 is disposed at the front end of the passenger module 130 .
[0130] In some embodiments, the first electrical interface 113 is plugged into the second electrical interface 134. The plugging and unplugging direction can be along the front-to-back, up-down, or left-to-right direction.
[0131] In some embodiments, the passenger assembly 130 includes a braking part, which is configured to control the braking of the walking assembly 112. When the user sits or stands on the passenger assembly 131, it is convenient to control the walking assembly 112. In some embodiments, the braking part is wirelessly connected to the walking assembly 112, and when the braking part is in a braking state, the walking assembly 112 is braked. The braking part can be a button or an operating lever. In some embodiments, the braking part is connected to the walking assembly 112, and the braking part includes a brake assembly, and the brake assembly includes a brake pedal and a drum brake. The brake pedal is provided on the passenger assembly 131 for the convenience of the user stepping on it, and the drum brake is provided on the walking assembly 112, and the brake pedal and the drum brake are connected by a brake connector.
[0132] The manned assembly 130 includes a pedal 1311 and a connecting assembly 133 connecting the mainframe 110 and the pedal 1311. The connecting assembly 133 is detachably connected to the mainframe 110. The connecting assembly 133 and the mainframe 110 can be connected by a pin assembly, a hook or a bolt assembly for easy installation and removal.
[0133] In the front-to-back direction, the distance between the main unit 110 and the pedal 1311 is greater than or equal to 800 mm and less than or equal to 900 mm. By setting an appropriate distance, the user is provided with operating space, which is convenient for steering and avoids the handle assembly 120 being too close to the user.
[0134] In some embodiments, the connecting assembly 133 is retractable to accommodate various user needs. In one conceivable embodiment, the connecting assembly 133 includes a hydraulic rod that is hydraulically driven to extend or retract to adjust the distance between the main unit 110 and the pedal 1311.
[0135] In some embodiments, the connection assembly 133 includes a connection plate 1331, the passenger portion 131 is disposed at the rear end of the connection plate 1331, and the front end of the connection plate 1331 is connected to the host 110. The connection plate 1331 can also be used as a shelf to facilitate the placement of some commonly used items.
[0136] As another embodiment, referring to Figures 7 to 12, the power tool is a snowplow 200. Snowplow 200 includes a main unit 210, a handle assembly 220, and a passenger assembly 230. Main unit 210 includes a snowplow assembly 210, a main unit housing 211, and a travel assembly 212. Main unit housing 211 supports snowplow assembly 210, and travel assembly 212 is connected to main unit housing 211. Handle assembly 220 is connected to main unit 210, and passenger assembly 230 is connected to main unit 210. Passenger assembly 230 includes a passenger section 231 for supporting a user. When snowplow 200 is in motion, the user can be positioned on passenger section 231, and the snowplow 200 drives the user forward without the user having to exert any effort.
[0137] The snowplow 200 of the present application is an improvement over a push-type snowplow. By adding a passenger unit 230, the user no longer needs to walk with the snowplow 200. Instead, the user stands or sits on the passenger unit 231, and the snowplow 200 drives the user forward. The snowplow 200 weighs greater than or equal to 40 kg and less than or equal to 100 kg.
[0138] The manned assembly 230 can be connected to the rear of the host 210 to facilitate the user to hold the handle assembly 220. In some embodiments, the manned assembly 230 can also be connected to the left or right side of the host 210, and the handle assembly 220 can also be detachable.
[0139] In some embodiments, the manned portion 231 includes a seat on which the user can sit to increase comfort. In some embodiments, the manned portion 231 includes a pedal 2311 on which the user can stand to save space.
[0140] Snowplow 200 has a push mode and a passenger mode. When in push mode, the passenger assembly 230 is in a first position relative to the main unit 210. When in passenger mode, the passenger assembly 230 is in a second position relative to the main unit 210. In push mode, the user can stand on the ground, holding onto the handle assembly 220, and walk along with the snowplow 200. In this position, the passenger assembly 230 is in the first position relative to the main unit 210, preventing interference with the user's movement. In passenger mode, the passenger assembly 230 is in the second position relative to the main unit 210, allowing the user to position themselves in the passenger unit 231 and be guided by the snowplow 200, eliminating the need for manual effort and saving both time and effort.
[0141] In some embodiments, the passenger assembly 230 is detachable from the main machine 210. When the snowplow 200 is in push mode, the passenger assembly 230 is detached from the main machine 210. This detachable passenger assembly 230 saves space and facilitates storage. In passenger mode, the passenger assembly 230 is attached to the main machine 210. The passenger assembly 230 and the main machine 210 can be connected using easily detachable components such as pins, hooks, and plugs.
[0142] When the snowplow 200 is in the push mode, the passenger assembly 230 is in a first position relative to the main body 210. When the snowplow 200 is in the manned mode, the passenger assembly 230 is in a second position relative to the main body 210. By switching the position of the passenger assembly 230, the passenger assembly 230 does not interfere with the user in the push mode, thus saving space.
[0143] In some embodiments, the passenger assembly 230 is foldable or rotatable to switch between a first position and a second position. As a feasible embodiment, the passenger section 231 includes a pedal 2311, which is foldable or rotatable relative to the main unit 210. Specifically, one end of the pedal 2311 is rotatably connected to the main unit housing 211, and the pedal 2311 can switch between a horizontal position and a vertical position. The pedal 2311 and the main unit housing 211 can be rotatably connected via a hinge assembly. When the pedal 2311 is in the horizontal position, the passenger assembly 230 is in the second position relative to the main unit 210, and a user can stand on the pedal 2311. When the pedal 2311 is in the vertical position, the passenger assembly 230 is in the first position relative to the main unit 210, and the user can stand on the ground and walk along with the snowplow 200. Since the pedal 2311 is in the vertical position, space is saved.
[0144] In some embodiments, the manned assembly 230 has no power of its own, and the power for the snowplow 200 to move comes from the walking assembly 212. The walking assembly 212 includes walking wheels 2121 and a walking motor. When in use, the walking motor drives the walking wheels 2121 to move, thereby driving the entire machine to move.
[0145] Snowplow 200 also includes a control device 200a for controlling travel assembly 212. In some embodiments, control device 200a receives user input from handle assembly 220 to control travel assembly 212. In other embodiments, when snowplow 200 is in push mode, control device 200a receives user input from handle assembly 220 to control travel assembly 212. When snowplow 200 is in passenger mode, control device 200a receives user input from at least passenger assembly 230 to control travel assembly 212.
[0146] In the manned mode, since the user is located in the manned part 231, it is convenient to operate the manned component 230. At this time, the user does not need to hold the handle component 220, so the control device 200a at least receives the user's input to the manned component 230 to control the walking component 212, which is convenient for user operation.
[0147] When the snowplow 200 is in passenger mode, the control device 200a is configured to receive user input on the handle assembly 220 to control the travel assembly 212. In passenger mode, the user is located in the passenger section 231 and can operate the passenger assembly 230 or the handle assembly 220, giving the user more options and improving the user experience.
[0148] In the push mode, the control device 200a is in a first control state when receiving user input from the handle assembly 220 to control the travel assembly 212. In the passenger mode, the control device 200a is in a second control state when receiving at least user input from the passenger assembly 230 to control the travel assembly 212. The control device 200a automatically distinguishes between the passenger mode and the push mode to switch between the first and second control states. The automatic distinction between the passenger mode and the push mode by the control device 200a facilitates timely switching between the first and second control states to meet user needs.
[0149] In some embodiments, the control device 200a includes a selection switch 250. The user switches between the manned mode and the push mode by operating the selection switch 250. The selection switch 250 has a pressed state and a raised state. In the pressed state, the snowplow 200 is in the manned mode, and in the raised state, the snowplow 200 is in the push mode.
[0150] The control device 200a is configured to control the walking assembly 212 to enter a forward mode, a backward mode, or a steering mode. In some embodiments, the control device 200a includes a mode button 240. By operating the mode button 240, the walking assembly 212 is configured to switch between a forward mode, a backward mode, and a steering mode. The mode button 240 can be provided on both the handle assembly 220 and the manned assembly 230 to facilitate the user to operate according to their own needs. In some embodiments, the control device 200a includes a voice receiving module. The voice receiving module receives voice to control the walking assembly 212 to switch between a forward mode, a backward mode, and a steering mode. The voice receiving module can be provided on both the handle assembly 220 and the manned assembly 230 to facilitate the user to operate according to their own needs.
[0151] The control device 200a is configured to adjust the speed of the walking component 212. In some embodiments, the speed of the walking component 212 can be adjusted by a speed adjustment button. In some embodiments, the speed of the walking component 212 can be adjusted by a voice receiving module.
[0152] In some embodiments, the passenger assembly 230 includes a pedal 2311, which includes a tread area 2311a. The tread area 2311a is equipped with a pressure sensor, and the snowplow 200 moves forward or backward based on the pressure value of the pressure sensor. In one achievable embodiment, the tread area 2311a is divided into a front tread area 2311a and a rear tread area 2311a. When the pressure value in the front tread area 2311a is greater than a first set value and the pressure in the rear tread area 2311a is less than a second set value, the snowplow 200 moves forward. When the pressure value in the front tread area 2311a is less than the second set value and the pressure in the rear tread area 2311a is greater than the first set value, the snowplow 200 moves backward. The first set value is greater than the second set value.
[0153] Furthermore, the snowplow 200 can adjust its speed based on the pressure value of the pressure sensor. In one practicable embodiment, the tread area 2311a is divided into a front tread area 2311a and a rear tread area 2311a. When the pressure value in the front tread area 2311a is greater than a first set value and less than a third set value, the snowplow 200 moves forward at a first speed. When the pressure value in the front tread area 2311a is greater than the third set value, the snowplow 200 moves forward at a second speed.
[0154] In some embodiments, the tread area 2311a includes at least a left tread area 2311a and a right tread area 2311a, and the snowplow 200 turns according to the pressure difference between the left tread area 2311a and the right tread area 2311a. As a feasible embodiment, the left tread area 2311a is divided into a front tread area 2311a and a rear tread area 2311a, and the right tread area 2311a is divided into a front tread area 2311a and a rear tread area 2311a. When the snowplow 200 moves forward, when the pressure value of the front tread area 2311a of the left tread area 2311a is greater than the pressure value of the front tread area 2311a of the right tread area 2311a, and the difference between the two is greater than or equal to a first set difference, the snowplow 200 turns left.
[0155] The pressure sensor and torque sensor are both electrically connected to the control device 200 a , and the control device 200 a controls the travel component 212 by receiving pressure values and torque values.
[0156] In some embodiments, the passenger assembly 230 includes passenger wheels 232 , which support the passenger portion 231 . When the entire machine moves, the passenger wheels 232 are driven to move, thereby driving the passenger portion 231 to move.
[0157] In some embodiments, the passenger assembly 230 is powered, and the power for the movement of the snowplow 200 can come from the travel assembly 212 or the passenger assembly 230. Specifically, the passenger assembly 230 includes passenger wheels 232 and a passenger motor. The passenger wheels 232 support the passenger section 231, and the passenger motor is connected to the passenger wheels 232 to drive the passenger wheels 232. The passenger motor drives the passenger wheels 232 to move, thereby driving the entire snowplow 200.
[0158] In some embodiments, the passenger travel motor is a hub motor.
[0159] In some embodiments, two passenger travel wheels 232 are provided, spaced apart in the left-right direction, and a passenger travel motor is provided for each passenger travel wheel 232. Steering can be controlled based on the speed difference between the two passenger travel motors. In one achievable embodiment, when the speed of the left passenger travel motor is greater than the speed of the right passenger travel motor, and the difference between the speeds is greater than or equal to a first speed value, the snowplow 200 turns right.
[0160] When the passenger travel motor is turned on to drive the passenger travel wheels 232, the travel motor of the travel assembly 212 is turned off to prevent interference.

[0166] In other embodiments, the passenger module 230 includes a first power source 230a independent of the battery pack 210a. The first power source 230a powers the passenger travel motor. When the battery pack 210a, which is powering the travel module 212, runs out of power, the first power source 230a can be used to power the passenger travel motor, thereby extending the vehicle's battery life.
[0167] The passenger assembly 230 includes a control assembly configured to control the forward, reverse, or steering movement of the passenger wheels 232.
