Description
Technical Field
[0001] This application relates to the field of energy storage technology, specifically to an energy storage robot and an energy storage system. Background Technology
[0002] When users are outdoors and need electricity, they typically choose outdoor power supplies. However, the weight of outdoor power supplies increases with the amount of stored energy, making it impossible to simultaneously meet the needs of convenience and high capacity for outdoor power use. Therefore, energy storage robots equipped with photovoltaic modules have autonomous power generation capabilities, which can solve the above problems to some extent.
[0003] However, photovoltaic modules that can generate sufficient power are large in size, which leads to a large space requirement for energy storage robots. Utility Model Content
[0004] This application provides an energy storage robot and an energy storage system.
[0005] This application provides an energy storage robot. The energy storage robot includes a body, a moving component, a battery module, and a photovoltaic module. The body has a receiving cavity. The moving component is disposed on the body. The moving component is configured to drive the body to move relative to a supporting surface. The battery module is housed in the body. The photovoltaic module is disposed on the body. The photovoltaic module is configured to convert solar energy into electrical energy. The photovoltaic module includes a photovoltaic element and a movable structure. The movable structure includes a lifting component and multiple folding components. The lifting component is configured to extend and retract in the height direction. The photovoltaic element is connected to the multiple folding components. The folding component includes a first end and a second end opposite to each other. The first end is connected to the lifting component. In the retracted state, the photovoltaic element is housed in the receiving cavity; in the unfolded state, the lifting component drives the photovoltaic element to rise from the receiving cavity to a predetermined lifting position in the height direction, and the folding components drive the photovoltaic element to unfold radially and protrude from the body, the radial direction being perpendicular to the height direction. The battery module is housed in the housing, and the photovoltaic module is electrically connected to the battery module and outputs electrical energy to the battery module.
[0006] In some embodiments, in the unfolded state, a plurality of the folding members unfold radially outward synchronously around the lifting member, and the folding members cause the photovoltaic element to be tensioned.
[0007] In some embodiments, in the retracted state, the plurality of folding members converge radially around the lifting member, causing the photovoltaic element to relax and retract.
[0008] In some embodiments, the folding member is foldable, and the movable structure further includes a connecting ring. The connecting ring is sleeved on the lifting member and is slidable along the height direction of the lifting member, and the portion of the folding member between the first end and the second end is connected to the connecting ring.
[0009] In some embodiments, the lifting member is provided with a first locking portion, and the connecting ring is provided with a second locking portion that cooperates with the first locking portion. When the first locking portion and the second locking portion are locked, the photovoltaic module maintains the unfolded state. When the first locking portion and the second locking portion are unlocked, the lifting member can extend and retract in the height direction, and the folding member can move in the radial direction.
[0010] In some embodiments, the lifting member further includes an unlocking part. The first locking part includes a pin hole; the second locking part includes a pin disposed on the connecting ring, and the pin is sleeved with an elastic element. When the first locking part and the second locking part are locked, the elastic element drives the pin to insert into the pin hole. When the first locking part and the second locking part are unlocked, the unlocking part pushes the pin away from the pin hole.
[0011] In some embodiments, the energy storage robot further includes a support assembly. The support assembly is foldably disposed on the body and configured to switch between a retracted state and a supported state. In the retracted state, the support assembly is spaced apart from the bearing surface; in the supported state, at least a portion of the support assembly is located outside the body and abuts against the bearing surface.
[0012] In some embodiments, the support assembly includes multiple support members. Each support member includes a main body, a rotating part, and a self-locking part. The rotating part connects the main body and the housing and rotates the main body relative to the housing to switch between the retracted state and the supported state. The self-locking part is coupled to the rotating part and the main body, and is electrically connected to the battery module and / or the photovoltaic module. When the battery module and / or the photovoltaic module powers the self-locking part, the self-locking part locks the rotating part and the main body; when the power to the self-locking part is de-energized, the self-locking part unlocks the rotating part and the main body.
[0013] In some embodiments, the energy storage robot further includes a counterweight assembly. The counterweight assembly is housed within the robot body and includes a counterweight component and a counterweight drive component, the counterweight drive component being configured to drive the counterweight component to move relative to the robot body.
[0014] In some embodiments, the adjustment assembly includes a first actuation unit, a bracket, a support platform, and a second actuation unit. The first actuation unit is disposed within the fuselage. The bracket is connected to the first actuation unit, and the bracket is at least partially located outside the fuselage, on one side where the top of the fuselage is located. The support platform is configured to support the photovoltaic module. The second actuation unit is disposed on the bracket and connected to the support platform. The first actuation unit is configured to drive the bracket to rotate relative to the fuselage, thereby causing the bracket to rotate the photovoltaic module and change the yaw angle of the photovoltaic module. The second actuation unit is configured to drive the support platform to rotate relative to the bracket, thereby causing the support platform to rotate the photovoltaic module and change the pitch angle of the photovoltaic module.
[0015] This application also provides an energy storage system. The energy storage system includes the energy storage robot and charging device described in any of the above embodiments, wherein the charging device is configured to provide electrical energy to the energy storage robot.
[0016] In the energy storage robot and system of this application, the photovoltaic element is housed in a receiving cavity when folded, reducing the volume of the photovoltaic module in the folded state. When the photovoltaic module needs to generate electricity, the lifting component lifts the photovoltaic element from the receiving cavity to a predetermined lifting position in the height direction, and the folding component causes the photovoltaic element to unfold radially and protrude from the body. The light-receiving surface area of the photovoltaic element outside the receiving cavity is increased, meeting the power generation requirements. Thus, while ensuring the power generation efficiency of the energy storage robot, miniaturization of the energy storage robot is achieved.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0025] When users are outdoors and need electricity, they typically choose outdoor power sources. However, the weight of outdoor power sources increases with the amount of stored energy, making it impossible to simultaneously meet the needs of convenience and high capacity for outdoor power use. Therefore, energy storage robots equipped with photovoltaic modules have autonomous power generation capabilities, which can solve the above problems to some extent. However, photovoltaic modules that provide sufficient power generation are large, resulting in a large space occupation for the energy storage robot. To solve this problem, this application provides an energy storage robot 100 (… Figure 1 and Figure 2 (as shown) and energy storage system 1000 ( Figure 6 (As shown).
[0026] Please see Figure 1 and Figure 2This application provides an energy storage robot 100. The energy storage robot 100 includes a body 10, a battery module 30, a moving component 50, and a photovoltaic module 90. The body 10 has a receiving cavity 101. The moving component 50 is disposed on the body 10. The moving component 50 is configured to drive the body 10 to move relative to a supporting surface. The battery module 30 is housed in the body 10. The photovoltaic module 90 is disposed on the body 10. The photovoltaic module 90 is configured to convert solar energy into electrical energy. The photovoltaic module 90 includes a photovoltaic element 91 and a movable structure 93. The movable structure 93 includes a lifting component 931 and multiple folding components 933. The lifting component 931 is configured to extend and retract in the height direction Z. The photovoltaic element 91 is connected to the multiple folding components 933. The folding component 933 includes a first end 9331 and a second end 9333 opposite to each other. The first end 9331 is connected to the lifting component 931. In the retracted state, the photovoltaic module 91 is housed in the receiving cavity 101. In the unfolded state, the lifting component 931 lifts the photovoltaic module 91 from the receiving cavity 101 to a predetermined lifting position in the height direction Z, and the folding component 933 unfolds the photovoltaic module 91 in the radial direction S and protrudes from the body 10, with the radial direction S perpendicular to the height direction Z. The battery module 30 is housed in the body 10, and the photovoltaic module 90 is electrically connected to the battery module 30, outputting electrical energy to the battery module 30.
[0027] The energy storage robot 100 is a power distribution device integrating energy storage, autonomous mobility, and intelligent control functions. The energy storage robot 100 can autonomously move to a target location based on the user's power demand and provide regular or temporary power supply. The energy storage robot 100 can be used, but is not limited to, in scenarios such as outdoor camping, dynamic energy management, emergency disaster relief, and microgrid support to address the power needs of areas without a power grid or with unstable power. The energy of the energy storage robot 100 can be provided by battery modules 30 (rechargeable or non-rechargeable battery modules) or power generation structures (such as wind turbine modules 80 and photovoltaic modules 90) installed within the energy storage robot 100, ensuring that the energy storage robot 100 has sufficient stored energy.
[0028] The housing 10 is a structure used to mount other components. The cross-sectional shape of the housing 10 can be, but is not limited to, circular, elliptical, rectangular, or other polygonal shapes, and the material of the housing 10 can be plastic or metal. When the housing 10 is made of plastic, it has good insulation performance, low cost, and light weight. When the housing 10 is made of metal, it has high strength, good wear resistance, and a long service life.
[0029] Battery module 30 is the core module of the energy storage robot 100, used for storing and releasing electrical energy. Depending on the different application scenarios of the energy storage robot 100, the energy storage robot 100 has different capacities, meaning the battery module 30 has different capacities. For example, in small household or commercial energy storage robots 100, the capacity of battery module 30 is typically from several kilowatt-hours to tens of kilowatt-hours. In industrial energy storage robots 100, the capacity of battery module 30 is typically from tens of kilowatt-hours to hundreds of kilowatt-hours. Battery module 30 is housed within the body 10 and can be electrically connected to other functional components. Battery module 30 can be a rechargeable battery module or a non-rechargeable battery module. When battery module 30 is a rechargeable battery module, the energy storage robot 100 can be charged via a charging device 300 (such as a charging pile) to replenish its electrical energy. When the battery module 30 is a non-rechargeable battery module, the energy storage robot 100 can replace the battery module 30 via the charging device 300 to replenish its power. The charging device 300 is a device that provides power to devices with energy storage functions. For example, the charging device 300 can provide power to new energy vehicles, the energy storage robot 100, or other energy storage devices. This application uses a charging pile as an example to illustrate the charging device 300. The charging device 300 provides power to the energy storage robot 100 by charging the battery module 30 in the energy storage robot 100, and also by replacing the battery module 30 in the energy storage robot 100 (battery swapping).
[0030] The moving component 50 is a module in the energy storage robot 100 used to drive the movement of the energy storage robot 100. The moving component 50 is disposed on the body 10 of the energy storage robot 100, typically on the bottom side of the body 10 (the side of the body 10 opposite to the bearing surface when the energy storage robot 100 is supported on the bearing surface). The moving component 50 includes a drive element (not shown) and moving parts. The drive element is a component that provides power, such as a drive motor, internal combustion engine, or pneumatic motor. The moving parts are components that drive the movement of the body 10, such as tracks or wheels. For example, the moving parts include tracks. Tracks are highly adaptable and can adapt to various terrains, including mud, rough, and uneven terrain; tracks have a high load-bearing capacity and can carry heavier weights; tracks have stronger traction and can travel on steeper slopes; tracks have a larger ground contact area and can provide more stable movement. For example, the moving component includes wheels. Wheels have less rolling friction, enabling higher speeds and greater flexibility, allowing for easier turning and U-turns. The moving drive component is directly connected to the actuator, transmitting power directly to the actuator to drive its movement, thereby enabling the moving component 50 to move the energy storage robot 100. The movement of the energy storage robot 100 driven by the moving component 50 can be, but is not limited to, translation, rotation, or a combination of translation and rotation. Furthermore, the moving component 50 may also include a transmission component connecting the moving drive component and the actuator. That is, the moving drive component is indirectly connected to the actuator through the transmission component, transmitting power directly from the moving drive component to the transmission component, which then transmits it to the actuator to move it, thereby enabling the moving component 50 to move the energy storage robot 100.
[0031] A photovoltaic module 90 is a component that converts light energy into electrical energy to charge a device electrically connected to it (such as a battery module 30). The battery module 30 and the photovoltaic module 90 can be directly connected via cables, or they can be connected through intermediate devices such as junction boxes or combiner boards. The photovoltaic module 90 can be a retractable or foldable structure, correspondingly including a retracted state and an extended state. The projected area of the photovoltaic module 90 in the XY plane when in the extended state is larger than the projected area of the photovoltaic module 90 in the XY plane when in the retracted state. There can be one or multiple photovoltaic modules 90.
[0032] The receiving cavity 101 is at least used to house the photovoltaic module 90 when it is in the retracted state. The photovoltaic element 91 is used to perform photoelectric conversion to generate electrical energy. The photovoltaic element 91 can be different types of solar energy conversion devices such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells. Among them, the photovoltaic element 91 of this application is a flexible photovoltaic element 91 such as a thin-film solar cell. The photovoltaic element 91 includes a light-facing side and a back-light side. The light-facing side is the side of the photovoltaic element 91 that faces the sun, and the light-facing side faces the sun to convert solar energy into electrical energy; the back-light side is the opposite side of the light-facing side of the photovoltaic element 91.
[0033] The lifting member 931 is used to extend and retract in the height direction Z to drive the photovoltaic module 90 out of or into the receiving cavity 101. The lifting member 931 is linked to the body 10 for connecting and securing multiple folding members 933. Exemplarily, the lifting member 931 is located at the top of the body 10 and can extend protrudingly in the height direction Z. The lifting member 931 includes multiple telescopic rods that can slide relative to each other. The telescopic rods can extend and retract in the height direction Z. In the unfolded state, the telescopic rods of the lifting member 931 extend away from the top of the body 10, and in the retracted state, the telescopic rods of the lifting member 931 retract towards the top of the body 10.
[0034] The first end 9331 of the folding member 933 is connected to the lifting member 931. Multiple folding members 933 are connected to the lifting member 931, and their projections on the XY plane are arranged radially. The folding member 933 is connected to the backlight surface. The folding member 933 is used to drive the photovoltaic element 91 to move relative to the body 10 to change the light-receiving area of the photovoltaic element 91. In the retracted state, the folding member 933 drives the photovoltaic element 91 to fold up, and the photovoltaic element 91 is housed within the body 10 and fits against the lifting member 931. The photovoltaic element 91 is housed within the receiving cavity 101 inside the body 10, which protects the photovoltaic element 91 from environmental factors (such as wind, sand, rain, and snow) or physical impacts, extends the service life of the photovoltaic element 91, and reduces the size of the energy storage robot 100.
[0035] like Figure 1 and Figure 2 As shown, in the unfolded state, the folding component 933 causes the photovoltaic component 91 to protrude relative to the body 10 and extend outward relative to the lifting component 931. The light-receiving area of the photovoltaic component 91 in the folded state is smaller than the light-receiving area of the photovoltaic component 91 in the unfolded state.
[0036] In the energy storage robot 100 of this application, the photovoltaic component 91 is housed in the receiving cavity 101 in the retracted state, reducing the volume of the photovoltaic module 90 in the retracted state. When the photovoltaic module 90 needs to generate electricity, the lifting component 931 lifts the photovoltaic component 91 from the receiving cavity 101 to a predetermined lifting position in the height direction Z, and the folding component 933 unfolds the photovoltaic component 91 in the radial direction S and protrudes from the body 10. The light-receiving surface area of the photovoltaic component 91 outside the receiving cavity 101 is increased, meeting the power generation requirements, thereby ensuring the power generation efficiency of the energy storage robot 100 while realizing the miniaturization of the energy storage robot 100.
[0037] Please see Figure 1 and Figure 2 In some embodiments, in the unfolded state, multiple folding members 933 unfold synchronously outward in the radial direction S around the lifting member 931, and the folding members 933 drive the flexible photovoltaic member 91 to be tensioned.
[0038] Specifically, Figure 2 Two folding members 933 are shown, located on opposite sides of the lifting member 931 in a radial direction S. When switching from the retracted state to the unfolded state, multiple folding members 933 extend synchronously with their second ends 9333 outward from the lifting member 931, centered on the lifting member 931, enabling a rapid transition of the photovoltaic module 90 from the retracted state to the unfolded state. As the folding members 933 unfold radially S, the flexible photovoltaic element 91 connected to them is stretched synchronously, gradually becoming taut from a relaxed or folded state. The taut flexible photovoltaic element 91 has a large light-receiving area, which improves the photoelectric conversion efficiency of the photovoltaic module 90.
[0039] Please see Figure 1 and Figure 2 In some embodiments, in the retracted state, multiple folding members 933 converge radially S around the lifting member 931, causing the flexible photovoltaic member 91 to relax and retract.
[0040] Specifically, when switching from the unfolded state to the retracted state, multiple folding components 933, centered on the lifting component 931, move their second ends 9333 towards the lifting component 931 simultaneously. The flexible photovoltaic component 91 connected to the folding component 933 loses the tension provided by the folding component 933, and the flexible photovoltaic component 91 relaxes from a taut state. In this way, the folding component 933 can quickly reduce the light-receiving area of the photovoltaic component 91, and can quickly switch the photovoltaic module 90 from the unfolded state to the retracted state. Thus, when the energy storage robot 100 encounters severe weather (such as strong winds), the photovoltaic component 91 can quickly reduce its light-receiving area, reduce the wind resistance of the energy storage robot 100, protect the photovoltaic component 91, and reduce the risk of damage.
[0041] Please see Figure 1 and Figure 2 In some embodiments, the folding member 933 is foldable, and the movable structure 93 further includes a connecting ring 935. The connecting ring 935 is sleeved on the lifting member 931 and is slidable along the height direction Z of the lifting member 931. The portion of the folding member 933 between the first end 9331 and the second end 9333 is connected to the connecting ring 935.
[0042] Specifically, a folding member 933 includes multiple telescopic portions that can be folded relative to each other. For example, in the case where a folding member 933 includes four telescopic portions that can be folded relative to each other, the telescopic portions are a first telescopic portion 9335, a second telescopic portion 9336, a third telescopic portion 9337, and a fourth telescopic portion 9338. The first telescopic portion 9335 is connected to the photovoltaic element 91. The opposite ends of the second telescopic portion 9336 are rotatably connected to the first telescopic portion 9335 and the third telescopic portion 9337, respectively. The opposite ends of the third telescopic portion 9337 are rotatably connected to the second telescopic portion 9336 and the fourth telescopic portion 9338, respectively. One end of the fourth telescopic portion 9338 is connected to the lifting rod 931. A connecting ring 935 is used to drive the folding member 933 to unfold or fold in the radial direction S. The middle portion of each folding member 933 between the first end 9331 and the second end 9333 is connected to the connecting ring 935. Exemplarily, the second telescopic portion 9336 and the fourth telescopic portion 9338 are connected to the connecting ring 935 via a connecting rod 937.
[0043] When the photovoltaic module 90 switches from the retracted state to the unfolded state, the connecting ring 935 slides upward along the lifting member 931 in the height direction Z. The connecting ring 935 causes the ends of the first telescopic part 9335, the second telescopic part 9336, the third telescopic part 9337, and the fourth telescopic part 9338 that are not connected to the lifting member 931 to move away from the lifting member 931. This causes the second end 9333 of the folding member 933 to extend away from the lifting member 931. The included angles between the first telescopic part 9335 and the second telescopic part 9336, between the second telescopic part 9336 and the third telescopic part 9337, and between the third telescopic part 9337 and the fourth telescopic part 9338 increase and approach 180°. The included angle between the fourth telescopic part 9338 and the lifting member 931 approaches 90°. This causes the photovoltaic module 91 to be tensioned and protrude from the body 10 to the unfolded state.
[0044] When the photovoltaic module 90 switches from the unfolded state to the retracted state, the connecting ring 935 slides downward along the lifting member 931 in the height direction Z. The connecting ring 935 drives the ends of the first telescopic part 9335, the second telescopic part 9336, the third telescopic part 9337, and the fourth telescopic part 9338 that are not connected to the lifting member 931 to approach the lifting member 931. This causes the second end 9333 of the folding member 933 to retract towards the lifting member 931. The included angles between the first telescopic part 9335 and the second telescopic part 9336, between the second telescopic part 9336 and the third telescopic part 9337, and between the third telescopic part 9337 and the fourth telescopic part 9338 decrease and approach 0°. The included angle between the fourth telescopic part 9338 and the lifting member 931 also approaches 0°. The folding member 933 releases the tension on the photovoltaic module 91, and the photovoltaic module 91 relaxes and retracts towards the lifting member 931.
[0045] The connecting ring 935 can drive multiple folding components 933 to move synchronously, avoiding interference or jamming caused by inconsistent movement between the folding components 933. In addition, the connecting ring 935 can ensure that the photovoltaic component 91 is subjected to uniform stress when it is unfolded or retracted, which helps to reduce local stress concentration in the flexible photovoltaic component 91 during repeated unfolding and retraction, and extends the service life of the photovoltaic component 91.
[0046] Please see Figure 2 and Figure 3 In some embodiments, the lifting member 931 is provided with a first locking part 9311, and the connecting ring 935 is provided with a second locking part 9351 that cooperates with the first locking part 9311. When the first locking part 9311 and the second locking part 9351 are locked, the photovoltaic module 90 remains in the unfolded state. When the first locking part 9311 and the second locking part 9351 are unlocked, the lifting member 931 can extend and retract in the height direction Z, and the folding member 933 can move in the radial direction S.
[0047] Specifically, the first locking part 9311 and the second locking part 9351 can be one or more, and are not limited in this application. This application describes one first locking part 9311 and one second locking part 9351 respectively. It is understood that the first locking part 9311 is located on the sliding path of the second locking part 9351. When the first locking part 9311 and the second locking part 9351 are locked, the photovoltaic module 90 can be maintained in the deployed state, preventing the photovoltaic module 90 from shaking under the action of external factors (such as wind, slight collisions or vibrations when the energy storage robot 100 moves), avoiding the photovoltaic module 90 from accidentally switching to the retracted state. The stable deployed state ensures that the photovoltaic module 91 can continuously receive sunlight, ensuring the photoelectric conversion efficiency of the photovoltaic module 90, and also avoids unnecessary relative movement and wear of the photovoltaic module 90 in the deployed state, reducing mechanical fatigue and helping to extend the service life of the photovoltaic module 90 and the support component 60.
[0048] Please see Figure 2 and Figure 3 In some embodiments, the lifting member 931 further includes an unlocking part 9313. The first locking part 9311 includes a pin hole 9315; the second locking part 9351 includes a pin 9353 disposed on the connecting ring 935, and an elastic member 939 is sleeved on the pin 9353. When the first locking part 9311 and the second locking part 9351 are locked, the elastic member 939 drives the pin 9353 to insert into the pin hole 9315. When the first locking part 9311 and the second locking part 9351 are unlocked, the unlocking part 9313 pushes the pin 9353 out of the pin hole 9315.
[0049] Specifically, when the photovoltaic module 90 switches from the retracted state to the unfolded state, the connecting ring 935 slides upward along the lifting member 931 in the height direction Z. During the sliding process, the elastic member 939 is in a compressed state and accumulates elastic potential energy. When the connecting ring 935 slides to the predetermined position of the unfolded state (i.e., the position of the first locking part 9311), the pin 9353 aligns with the pin hole 9315, the elastic potential energy accumulated by the elastic member 939 is released, and the pin 9353 is driven to insert into the pin hole 9315. In this way, the first locking part 9311 and the second locking part 9351 are locked, and the photovoltaic module 90 can maintain the unfolded state.
[0050] When the photovoltaic module 90 switches from the unfolded state to the retracted state, the unlocking part 9313 and the pin hole 9315 are opposite and spaced apart. Under the action of driving force, the unlocking part 9313 pushes the pin 9353, which has been inserted into the pin hole 9315, to overcome the elastic potential energy of the elastic member 939 and pushes the pin 9353 out of the pin hole 9315. The first locking part 9311 and the second locking part 9351 are unlocked.
[0051] Please see Figure 2In some embodiments, the energy storage robot 100 further includes a support assembly 60, which is foldably disposed on the body 10 and configured to switch between a retracted state and a supported state. In the retracted state, the support assembly 60 is spaced apart from the bearing surface. In the supported state, at least a portion of the support assembly 60 is located outside the body 10 and abuts against the bearing surface.
[0052] Specifically, the support component 60 is a module in the energy storage robot 100 that provides support for the robot. The folded state can be the state in which the support component 60 is located inside the body 10 and has difficulty or even cannot contact the bearing surface. The supported state can be the state in which at least a portion of the support component 60 is located outside the body 10 and can contact the bearing surface. It should be noted that when the energy storage robot 100 is moving smoothly, the support component 60 is in a folded state. In this state, the support component 60 is located inside the body 10. This reduces the forward drag of the energy storage robot 100, saves the energy required for its movement, and extends its endurance. Furthermore, compared to when the support component 60 is always outside the body 10, switching it to a folded state reduces interference and collisions between the support component 60 and external objects (such as obstacles on the support surface). This extends the service life of the support component 60 and prevents it from hindering the movement of the energy storage robot 100, thus improving its stability. Since the wind turbine 80 typically needs to rise to a certain height to capture wind energy, the support component 60 enhances the stability of the energy storage robot 100, preventing it from being blown over by the wind.
[0053] Please see Figure 2 In some embodiments, the support assembly 60 includes multiple support members 61. Each support member 61 includes a body portion 611, a rotating portion 613, and a self-locking portion 615. The rotating portion 613 connects the body portion 611 and the housing 10 and drives the body portion 611 to rotate relative to the housing 10, switching between a retracted state and a supported state. The self-locking portion 615 is coupled to the rotating portion 613 and the body portion 611, and is electrically connected to the battery module 30 and / or the photovoltaic module 90. When the battery module 30 and / or the photovoltaic module 90 energizes the self-locking portion 615, the self-locking portion 615 locks the rotating portion 613 and the body portion 611; when the power to the self-locking portion 615 is de-energized, the self-locking portion 615 unlocks the rotating portion 613 and the body portion 611.
[0054] The support assembly 60 includes a plurality of support members 61. For example, the support assembly 60 includes four support members 61, which are symmetrically distributed near the four corners of the body 10, thereby forming a large support surface after unfolding, preventing the energy storage robot 100 from shaking or overturning due to uneven bearing surface or external disturbances (such as strong winds).
[0055] The main body 611 is the structure in the support member 61 that abuts against the bearing surface and provides support. The end of the main body 611 that contacts the bearing surface may be provided with a wear-resistant, non-slip pad to increase friction with the bearing surface and ensure the reliability of the support. Under driving force, the rotating part 613 moves the main body 611 from a retracted state (closely attached to or housed within the body 10) to a supported state (extended and in contact with the bearing surface). The driving force can originate from a drive member housed within the energy storage robot 100.
[0056] The rotating part 613 is used to drive the main body 611 to rotate relative to the body 10. When it is necessary to switch the state of the support member 61, for example, from the storage state to the support state, the rotating part 613 rotates to drive the main body 611 to rotate synchronously around its connecting axis on the body 10, so that the end of the main body 611 away from the rotating part 613 contacts the bearing surface, thereby strengthening the support for the energy storage robot 100.
[0057] The self-locking part 615 is used to control whether the rotating part 613 can rotate. The self-locking part 615 is electrically connected to the battery module 30 and / or the photovoltaic module 90, and can receive electrical energy from the battery module 30 and / or the photovoltaic module 90. Exemplarily, the self-locking part 615 can be an electromagnetic brake or an electronically controlled locking pin, etc., and is not limited thereto. It is understood that the angle between the body part 611 and the bearing surface can change, whether in the stored state or the supported state. For example, the body part 611 can be at 90° or 30° with the bearing surface, that is, the body part 611 can rotate to multiple preset positions. The battery module 30 and / or photovoltaic module 90 supply power to the self-locking part 615. When energized, the self-locking part 615 locks the rotating part 613 and the main body 611, locking their position relative to the body 10 and preventing them from rotating. This allows the main body 611 to remain in a preset position, preventing displacement due to external forces and maintaining the stability of the energy storage robot 100 when stationary. When the battery module 30 and / or photovoltaic module 90 disconnects the power supply to the self-locking part 615, the self-locking part 615 unlocks the rotating part 613 and the main body 611, allowing them to rotate relative to the body 10. This allows the main body 611 to move to a preset position, thus switching between a storage state and a support state.
[0058] Please see Figure 4In some embodiments, the energy storage robot 100 further includes a counterweight assembly 70 housed in the body 10. The counterweight assembly 70 includes a counterweight 71 and a counterweight drive 73, the counterweight drive 73 being configured to drive the counterweight 71 to move relative to the body 10.
[0059] Specifically, the counterweight assembly 70 is used to adjust the center of gravity of the energy storage robot 100. A sliding groove 103 is provided inside the body 10. The sliding groove 103 can be arranged around the interior of the body 10, or it can be arranged along the length direction X and / or the width direction Y. This application illustrates two sliding grooves 103 extending along the length direction X and located on opposite sides of the width direction Y. A counterweight drive member 73 is provided on the counterweight 71 and can drive the counterweight 71 to be slidably accommodated within the sliding groove 103. There can be one or more counterweights 71, which is not limited in this application. The counterweight 71 is typically made of a high-density material, such as a steel block or a lead alloy block. The counterweight drive member 73 can control the direction and distance of movement of the counterweight 71, thereby changing the center of gravity of the energy storage robot 100.
[0060] Please see Figure 1 and Figure 5 In some embodiments, the adjustment assembly 40 includes a first actuation unit 41, a bracket 43, a support platform 45, and a second actuation unit 47. The first actuation unit 41 is disposed within the fuselage 10. The bracket 43 is connected to the first actuation unit 41, and at least partially extends outside the fuselage 10, located on the side where the top of the fuselage 10 is situated. The support platform 45 is configured to support the photovoltaic module 90. The second actuation unit 47 is disposed on the bracket 43 and connected to the support platform 45. The first actuation unit 41 is configured to drive the bracket 43 to rotate relative to the fuselage 10, thereby causing the bracket 43 to rotate the photovoltaic module 90 and change the yaw angle of the photovoltaic module 90. The second actuation unit 47 is configured to drive the support platform 45 to rotate relative to the bracket 43, thereby causing the support platform 45 to rotate the photovoltaic module 90 and change the pitch angle of the photovoltaic module 90.
[0061] The adjustment component 40 is used to support the photovoltaic module 90 and adjust its attitude angles. These attitude angles include roll angle, yaw angle, and pitch angle. The energy storage robot 100 can actively change the orientation of the photovoltaic module 90 based on the actual position of the sun in the sky (e.g., according to different times of day or different seasons of the year). On one hand, it can adjust the relationship between the photovoltaic module 91 and the angle of illumination based on real-time light intensity, improving the photoelectric conversion efficiency of the photovoltaic module 91. On the other hand, the adjustment component 40 can control the attitude angle of the photovoltaic module 91, improving the stability of the energy storage robot 100 in complex environments. For example, when the moving component 50 moves the energy storage robot 100, facing bumpy roads or inclined slopes, the adjustment component 40 can adjust the attitude angle of the photovoltaic module 91, thereby adjusting the center of gravity distribution of the energy storage robot 100, reducing the risk of rollover, and ensuring its smooth movement. In windy conditions, the adjustment component 40 can control the attitude angle of the photovoltaic component 91 to reduce or increase wind resistance, adapting to tailwind or headwind conditions. This not only helps maintain stability in windy conditions and prevents it from being overturned, but also regulates the driving acceleration and speed of the energy storage robot 100, keeping the acceleration and speed within the expected range, thus adapting to various complex working conditions.
[0062] The first actuation unit 41 is fixed inside the fuselage 10 and can rotate around its own axis (M1). The axis M1 of the first actuation unit 41 is parallel to the third direction Z. The bracket 43 is connected to the first actuation unit 41. The torque output by the first actuation unit 41 can drive the bracket 43 to rotate around the axis M1 of the first actuation unit 41. The torque output by the first actuation unit 41 is transmitted to the photovoltaic module 90 through the bracket 43, causing the photovoltaic module 90 to rotate around the axis M1 (vertical axis) of the first actuation unit 41 to change the yaw angle.
[0063] The second actuation unit 47 is fixed to the upper end of the bracket 43. The support platform 45 is fixed to the output end of the second actuation unit 47 on one side of the third direction Z, and supports the photovoltaic module 90 on the other side of the third direction Z. When the second actuation unit 47 outputs torque, the torque is transmitted to the photovoltaic module 90 through the support platform 45, causing the photovoltaic module 90 to rotate around the axis M2 (horizontal axis) parallel to the first direction X to change the pitch angle. In this way, the adjustment component 40 achieves yaw angle adjustment through the transmission between the first actuation unit 41, the bracket 43 and the photovoltaic module 90, and the adjustment component 40 achieves pitch angle adjustment through the transmission between the second actuation unit 47, the support platform 45 and the photovoltaic module 90. The first actuation unit 41 and the second actuation unit 47 are controlled independently and do not interfere with each other.
[0064] Please see Figure 6This application also provides an energy storage system 1000. The energy storage system 1000 includes an energy storage robot 100 according to any of the above embodiments and a charging device 300, wherein the charging device 300 is configured to provide electrical energy to the energy storage robot 100.
[0065] Specifically, in the above embodiments, the energy storage system 1000 is a system for storing, scheduling, and utilizing energy. The energy storage system 1000 includes an energy storage device (energy storage robot 100) for scheduling or utilizing energy, and an energy supply device for powering the energy storage robot 100. The energy storage system 1000 can be any system possessing the above functions, for example: the energy storage system 1000 is a cleaning system, the energy storage robot 100 is a cleaning robot, the energy supply device is a power supply base station, and the power supply base station supplies power to the cleaning robot so that the cleaning robot can move using electrical energy; the energy storage system 1000 is a logistics system, the energy storage robot 100 is a logistics robot, the energy supply device is a charging device, and the charging device supplies power to the logistics robot so that the logistics robot can move using electrical energy; the energy storage system 1000 is a new energy vehicle system, the energy storage robot 100 is a new energy vehicle, the energy supply device is a charging device, and the charging device supplies power to the new energy vehicle so that the new energy vehicle can move using electrical energy. This application takes the energy storage system 1000 as an example of a power dispatching system. In this case, the energy storage robot 100 is a mobile energy storage power source, and the power supply device is a charging device 300. The charging device 300 supplies power to the energy storage robot 100 so that the energy storage robot 100 can move using electrical energy and perform power dispatching and utilization.
[0066] It should be noted that the specific structure and properties of the charging device 300 in this embodiment are exactly the same as those of the charging device 300 in the above embodiment, and the specific structure and properties of the energy storage robot 100 in this embodiment are exactly the same as those of the energy storage robot 100 in the above embodiment, and will not be explained again here.
[0067] When the energy storage robot 100 arrives at the charging device 300, the charging device 300 can charge or replace the battery module 30 of the energy storage robot 100. Taking charging as an example, the charging device 300 can charge the energy storage robot 100 via wired charging or wireless charging. When the charging device 300 charges the energy storage robot 100 via wired charging, the energy storage robot 100 connects to the physical plug (such as Type 1, Type 2, GB / T, or a customized interface) of the charging device 300 through a connection device (not shown) or a guide device (not shown). In this case, the charging process of the charging device 300 to charge the energy storage robot 100 is simple, reliable, and fast. When the charging device 300 charges the energy storage robot 100 via wireless charging, both the energy storage robot 100 and the charging device 300 are equipped with induction coils. The induction coil of the charging device 300 generates a magnetic field and transfers energy to the energy storage robot 100 through the induction coil of the energy storage robot 100 to charge the battery module 30 of the energy storage robot 100. At this time, the charging device 300 and the energy storage robot 100 do not need to contact each other, so the energy storage robot 100 will not experience wear and tear, resulting in a better appearance and a longer service life. When the charging device 300 is swapping the battery for the energy storage robot 100, it directly replaces the battery module 30 with a fully charged one. This results in faster energy replenishment and a longer working time for the energy storage robot 100.
[0068] Since the energy storage system 1000 in this application embodiment includes an energy storage robot 100, it is understood that the energy storage system 1000 includes at least the same beneficial effects as the energy storage robot 100. Therefore, the beneficial effects of the energy storage system 1000 are described above with reference to the beneficial effects of the energy storage robot 100, and will not be repeated here.
[0069] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.
