Technical Field

[0001] This application relates to the field of energy storage technology, specifically to an energy storage robot, a charging device, 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 with autonomous mobility can solve these problems to some extent. However, due to the large size and weight of energy storage robots, and their limited degrees of freedom during movement, the automatic coordination between the energy storage robot and the charging device is usually relatively simple. The coordination between the charging module of the energy storage robot and the charging module of the charging device is not precise enough, resulting in low energy transfer efficiency and low charging efficiency for the energy storage robot.

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.

[0034] 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 large capacity for outdoor power use. Therefore, energy storage robots with autonomous mobility can solve these problems to some extent. However, due to the large size and weight of energy storage robots and their limited degrees of freedom during movement, the automatic coordination process between the energy storage robot and the charging device is usually relatively simple. The coordination between the charging module of the energy storage robot and the charging module of the charging device is not precise enough, resulting in low energy transfer efficiency and low charging efficiency for the energy storage robot. To solve this problem, this application provides an energy storage robot 100 ( Figure 1 As shown), charging device 300 ( Figure 1 (as shown) and energy storage system 1000 ( Figure 1 (As shown).

[0035] Please refer to this as well. Figure 1 The present application provides an energy storage system 1000 including an energy storage robot 100 and a charging device 300.

Please refer to [reference needed]. Figure 1 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 charging device 300 is a charging pile. The charging pile charges the energy storage robot 100 so that the energy storage robot 100 can move using electrical energy and perform power dispatching and utilization.

[0037] It should be noted that 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 embodiments below. 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 embodiments. It can be understood that the energy storage system 1000 includes at least the same beneficial effects as the energy storage robot 100 and / or the charging device 300. Therefore, for the beneficial effects of the energy storage system 1000, please refer to the beneficial effects of the energy storage robot 100 and / or the charging device 300 described below.

[0038] Please refer to this as well. Figure 1 and Figure 2 This application provides an energy storage robot 100. The energy storage robot 100 includes a body 10, a moving component 20, a battery module 30, a first charging module 40, and a connecting component 60. The moving component 20 is disposed on the body 10 and configured to move the body 10. The battery module 30 is mounted on the body 10 and electrically connected to the moving component 20. The battery module 30 is configured to provide electrical energy to the energy storage robot 100. The first charging module 40 is mounted inside the body 10 and electrically connected to the battery module 30. The first charging module 40 is configured to charge the battery module 30. The connecting component 60 is disposed on the body 10. The connecting component 60 includes a guide 61 and a connector 63. The guide 61 is configured to insert into a mating member 351 on the charging device 300 of the energy storage robot 100. The connector 63 is disposed on the guide 61 and configured to engage with the coupling 353 on the charging device 300 so that the energy storage robot 100 is connected to the charging device 300 and the first charging module 40 is engaged with the charging device 300 to charge the battery module 30.

[0039] Specifically, in the above embodiments, the energy storage robot 100 is a power distribution device integrating energy storage, autonomous movement, and intelligent control functions. The energy storage robot 100 can autonomously move to a target location according to 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 rechargeable battery modules, non-rechargeable battery modules, or charging structures (such as photovoltaic panels) installed within the energy storage robot 100, ensuring that the energy storage robot 100 has sufficient stored energy.

[0040] The body 10 is the main body of the energy storage robot 100, used to house and install other components of the energy storage robot 100 besides the body 100. In its normal use state when the energy storage robot 100 is placed on the ground, the side closer to the ground is the bottom. The material of the body 10 includes, but is not limited to, metal, plastic, or a combination of both. When the body 10 is made of metal, it has high structural strength, is not easily damaged, and provides better protection for other components housed within it, resulting in a long service life for the energy storage robot 100. When the body 10 is made of plastic, it is lighter and less expensive, giving the energy storage robot 100 a lightweight advantage.

[0041] The moving component 20 is a component in the energy storage robot 100 used to propel the robot 100. The moving component 20 is mounted on the body 10, typically at the bottom. The moving component 20 may include a drive element (not shown) and an actuator. The drive element is a power-providing component, such as a drive motor, internal combustion engine, or pneumatic motor. The actuator is a component for direct movement, such as tracks or wheels. The drive element is directly connected to the actuator and transmits power directly to the actuator to drive its movement, thereby enabling the moving component 20 to move the energy storage robot 100. The movement of the energy storage robot 100 by the moving component 20 can be, but is not limited to, translation, rotation, or a combination of translation and rotation. Furthermore, the mobile component 20 may also include a transmission component, which connects the driving component and the actuator. That is, the driving component is indirectly connected to the actuator through the transmission component. The driving component directly transmits power to the transmission component, and then transmits it to the actuator through the transmission component, so as to make the actuator move, thereby enabling the mobile component 20 to drive the energy storage robot 100 to move.

[0042] 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 energy storage robot 100 and can be electrically connected to other functional components such as the moving component 20 to provide them with power.

[0043] The first charging module 40 is used to charge the battery module 30. The first charging module 40 is located inside the body 10 to avoid the risk of short circuit due to water ingress. The first charging module 40 is electrically connected to the battery module 30 so that the first charging module 40 can store the received or generated electrical energy into the battery module 30 to replenish the power of the energy storage robot 100.

[0044] The connecting component 60 is used to connect the energy storage robot 100 to the charging device 300 for charging. Specifically, the connecting component 60 connects to the mating component 350 on the charging device 300 to achieve accurate docking between the energy storage robot 100 and the charging device 300. The connecting component 60 is disposed on the outer wall of the body 10, specifically at a position corresponding to the mating component 350 in the charging device 300. The guide member 61 is a structure in the connecting component 60 used to guide the process of the energy storage robot 100 engaging with the charging device 300 for charging the energy storage robot 100. The guide member 61 can be inserted into the mating component 351 in the mating component 350. In some embodiments, the guide member 61 is a guide post and the mating component 351 is a guide groove. The guide post can move in the guide groove so that the guide member 61 and the mating component 351 can move relative to each other and engage. In other embodiments, the guide member 61 is a guide groove, and the mating member 351 is a guide post. The guide post can slide in the guide groove so that the guide member 61 and the mating member 351 can move relative to each other and be inserted.

[0045] The connector 63 is a structure in the connecting assembly 60 used to further strengthen the connection between the energy storage robot 100 and the charging device 300 after the guide 61 and the mating member 351 are inserted. The connector 63 is disposed on the guide 61, specifically on the outer wall of the guide 61. After the guide 61 and the mating member 351 are inserted, the connector 63 can be aligned and engaged with the mating member 353 of the mating assembly 350 on the charging device 300. At this time, the energy storage robot 100 and the charging device 300 are connected through the engagement of the connector 63 and the mating member 353. The first charging module 40 and the charging structure in the charging device 300 (the second charging module 330, which will be described below) are aligned and engaged with each other. The first charging module 40 and the second charging module 330 interact to generate electrical energy to charge the battery module 30.

[0046] During the charging process of the energy storage robot 100 of this application, the connection component 60 and the mating component 350 on the charging device 300 are used to achieve an accurate and stable connection with the charging device 300. Specifically, the guide component 61 on the energy storage robot 100 is inserted into the mating component 351 on the charging device 300, and the connector 63 on the energy storage robot 100 is engaged with the connecting component 353 on the charging device 300. At this time, the energy storage robot 100 and the charging device 300 are precisely aligned, and the first charging module 40 of the energy storage robot 100 is precisely matched with the charging structure (second charging module 330) of the charging device 300. The energy transfer efficiency between the two is high, thereby improving the charging efficiency of the energy storage robot 100.

[0047] Please refer to Figure 1 and Figure 3 In some embodiments, the body 10 includes a sidewall 11, which faces the charging device 300 when the energy storage robot 100 is connected to the charging device 300. The first charging module 40 includes a first coil 41 and a first magnetic core 43. The first coil 41 is disposed on the sidewall 11. The first coil 41 is configured to sense the magnetic field generated by the charging device 300 to generate electrical energy and output it to the battery module 30. The first magnetic core 43 is disposed on the sidewall 11 and shields the first coil 41. The first magnetic core 43 is configured to guide the magnetic field to the first coil 41 and shield the magnetic field from propagating outwards from the first magnetic core 43.

[0048] Specifically, when the energy storage robot 100 is connected to the charging device 300 via the connecting component 60, the side wall 11 is the outer wall of the body 10 opposite to the charging device 300. As the energy storage robot 100 moves towards the charging device 300, the moving component 20 adjusts the positional relationship between the energy storage robot 100 and the charging device 300 so that the side wall 11 is opposite to the charging device 300. At this time, the side wall 11 is the wall closest to the charging device 300, thus placing the first charging module 40 on the side wall 11 allows the first charging module 40 to be closer to the charging structure in the charging device 300, thereby improving energy transfer efficiency.

[0049] The first coil 41 is a structure in the first charging module 40 used to sense the magnetic field generated by the charging device 300 and generate an induced current through electromagnetic induction to produce electrical energy. The material of the first coil 41 can be, but is not limited to, copper or aluminum. The first coil 41 is located on the side wall 11 and is situated within the magnetic field, storing the electrical energy converted from the magnetic field energy in the battery module 30. The first magnetic core 43 is a structure in the first charging module 40 used to guide and shield the magnetic field. The first magnetic core 43 is located on the side wall 11. Specifically, the first magnetic core 43 is close to the first coil 41 on the side away from the side wall 11 and shields the first coil 41 to separate it from other devices inside the energy storage robot 100. The first magnetic core 43 can guide the magnetic field generated by the charging device 300 to pass through the first coil 41 to a greater extent and maximize the generated induced current to improve energy transfer efficiency. At the same time, the first magnetic core 43 can shield the magnetic field, preventing the magnetic field from being transmitted outward from the first magnetic core 43 and affecting other devices inside the energy storage robot 100.

[0050] Therefore, the first charging module 40, through the first coil 41 and the first magnetic core 43, cooperates with the magnetic field generated by the charging device 300. On the one hand, the first magnetic core 43 guides the magnetic field and maximizes the induced current generated by the first coil 41. At this time, the first charging module 40 can replenish more electrical energy to the battery module 30, and the energy transfer efficiency of the energy storage system 1000 is relatively high. On the other hand, the first magnetic core 43 can shield the transmission of the magnetic field to other devices inside the energy storage robot 100, thus protecting other devices. The energy storage robot 100 can operate normally and has good safety performance.

[0051] Please refer to Figure 1 In some embodiments, the energy storage robot 100 further includes a positioning module 70. The positioning module 70 is disposed on the body 10 and configured to detect the real-time position of the energy storage robot 100. The moving component 20 moves the body 10 to a charging device 300 capable of charging the energy storage robot 100 based on the real-time position.

[0052] Specifically, the positioning module 70 is a module in the energy storage robot 100 used to detect the real-time position of the energy storage robot 100. The positioning module 70 is located on the body 10 to directly reflect the real-time position of the energy storage robot 100. In some embodiments, the positioning module 70 uses a Global Navigation Satellite System (GNSS) to receive satellite signals for positioning. GNSS can be, but is not limited to, Global Positioning System (GPS), GLONASS, Galileo Satellite Navigation System, or BeiDou Navigation Satellite System. In other embodiments, the positioning module 70 uses a cellular network for positioning, estimating the real-time position of the energy storage robot 100 by the strength or time difference of communication signals with nearby base stations. Furthermore, the positioning module 70 can also be used for navigation, tracking, and motion monitoring of the energy storage robot 100.

[0053] Understandably, the charging device 300 adapted to the energy storage robot 100 also has a positioning function. The energy storage robot 100 can internally store the position information of each charging device 300, and can also obtain the position information of each charging device 300 through communication with the cloud. Based on the real-time position provided by the positioning module 70 and the position of the charging device 300, the energy storage robot 100 controls the moving component 20 to move the body 10 to the charging device 300 that can charge the energy storage robot 100. Therefore, the energy storage robot 100 of this application can reach the location of the charging device 300 through the positioning module 70, and the energy storage robot 100 and the charging device 300 achieve initial positional coordination, facilitating more precise subsequent coordination.

[0054] Please refer to Figure 1 In some embodiments, the energy storage robot 100 also includes a camera 81 configured to acquire real-time images. The real-time images are used to identify the position of the mating part 351, and the moving component 20 moves the body 10 according to the position of the mating part 351 to align the guide 61 and the mating part 351.

[0055] Specifically, camera 81 is used to acquire images that include at least the charging device 300 to identify the position of the mating part 351, and further align the guide 61 and the mating part 351. Real-time images refer to the actual images of the charging device 300 captured by camera 81 at the moment of image acquisition, reflecting the relative positional relationship between the charging device 300 and the energy storage robot 100. In some embodiments, the real-time image only includes the charging device 300; in other embodiments, the real-time image includes both the charging device 300 and the energy storage robot 100. Camera 81 is mounted on the body 10, typically on the top of the body 10 or on a side other than the side wall 11, so that the captured real-time images clearly show the characteristics of the charging device 300, facilitating subsequent analysis and processing, and preventing camera 81 from interfering with the assembly process between the energy storage robot 100 and the charging device 300.

[0056] After the initial positioning of the energy storage robot 100 and the charging device 300 is achieved with the help of the positioning module 70, a more precise positioning is needed, specifically, the alignment of the guide 61 and the mating part 351. At this point, based on real-time images, the energy storage robot 100 can determine the specific position of the mating part 351. Therefore, the moving component 20 can further adjust the position of the body 10 according to the position of the mating part 351, so that the guide 61 and the mating part 351 are more precisely aligned and connected. The energy storage robot 100 controls the moving component 20 based on the real-time images provided by the camera 81, and the moving component 20 moves the body 10 to align the guide 61 and the mating part 351. Therefore, the energy storage robot 100 of this application can achieve a more precise positioning with the charging device 300 through the information provided by the camera 81, allowing for a more efficient subsequent charging process.

[0057] Please refer to Figure 2 and Figure 4 In some embodiments, the connector 63 is a magnetic element, and the mating element 353 is a magnetic element. A magnetic attraction force is generated between the connector 63 and the mating element 353, which drives the body 10 to move so that the guide 61 and the mating element 351 are aligned.

[0058] Specifically, the connector 63 is a magnetic structure and includes two poles with opposite magnetic properties. The connector 63 can be a single magnetic element, in which case its structure is relatively simple. Alternatively, the connector 63 can be an array of more than one magnetic element, in which case the magnetism of the connector 63 is stronger, allowing it to bond more tightly with other magnetic structures. The magnetic elements can be, but are not limited to, metallic magnetic materials or rare-earth magnetic materials, and the shape of each magnetic element can be, but is not limited to, a cube, cylinder, or sphere.

[0059] Correspondingly, the connector 353 is a magnetic component with opposite magnetic poles. The connector 353 can be a single magnetic component, in which case its structure is relatively simple. The connector 353 can also be an array of more than one magnetic component, in which case the magnetism of the connector 353 is stronger, allowing for tighter bonding with other magnetic structures. The magnetic component can be, but is not limited to, metallic magnetic materials or rare-earth magnetic materials, and the shape of each magnetic component can be, but is not limited to, a cube, cylinder, or sphere.

[0060] In the direction opposite to the connector 63 and the mating member 353, the magnetic poles on the opposite side of the connector 63 and the mating member 353 are opposite to those on the opposite side of the connector 63, so that a magnetic attraction force can be generated between them. The generated magnetic attraction force can drive the body 10 towards the mating member 353 in the direction of the force, that is, towards the charging device 300, so that the guide 61 can be more accurately aligned and inserted. The attraction force between the connector 63 and the mating member 353 pulls the energy storage robot 100, thereby realizing the alignment of the guide 61 and the mating member 351.

[0061] Therefore, the energy storage robot 100 of this embodiment can achieve more precise positioning between the energy storage robot 100 and the charging device 300 through the magnetic attraction between the connector 63 and the coupling 353, and the subsequent charging process can be carried out more efficiently.

[0062] In some embodiments, the energy storage robot 100 of this embodiment can achieve matching with the compatible charging device 300 by setting the magnetic pole distribution on the connector 63 and the magnetic pole distribution on the coupling 353, so as to avoid the energy storage robot 100 mismatched with the incompatible charging device 300, which would lead to failure to charge or even the risk of fire and explosion. For example, the magnetic poles on the opposite side of the connector 63 of the energy storage robot 100 and the coupling 353 of the compatible charging device 300 are N poles, and the magnetic poles on the opposite side of the coupling 353 of the compatible charging device 300 and the connector 63 are S poles. However, the magnetic poles on the opposite side of the coupling 353 of the incompatible charging device 300 and the connector 63 are N poles. In this case, the energy storage robot 100 can only be coupled with the compatible charging device 300, and in the case of mismatch, it will be unable to be coupled due to repulsive force. Therefore, the energy storage robot 100 can work accurately with the compatible charging device 300 to charge efficiently while avoiding fire and explosion.

[0063] Please refer to Figures 1 to 3In some embodiments, the guide member 61 includes a guide body 611 and at least two guide portions 613. In the engagement direction X between the guide member 61 and the mating member 351, the cross-sectional dimension of the guide body 611, cut by a plane perpendicular to the engagement direction X, gradually decreases. At least two guide portions 613 are disposed on the outer wall of the guide body 611 and are evenly distributed around the center of the guide body 611.

[0064] Specifically, the guide body 611 is the main body of the guide member 61, and it bears a significant amount of force during the insertion process between the guide member 61 and the mating member 351. The direction in which the guide member 61 and the mating member 351 are inserted is the engagement direction X. The guide body 611 can be cut into multiple sections by a plane perpendicular to the engagement direction X, and the size of each section represents the size of the guide body 611. Along the engagement direction X, the size of the cross-sections gradually decreases, meaning the outer contour size of the guide body 611 gradually decreases. Therefore, the guide body 611 will provide better guidance during the insertion process with the mating member 351.

[0065] The guide portion 613 is a structure used to further assist the guiding function of the guide body 611. In this case, the structure of the guide member 61 is relatively complex. The guide portion 613 reduces the possibility of misalignment or mis-insertion during the insertion of the guide member 61 and the mating member 351. There are at least two guide portions 613 to ensure that the guide member 61 can achieve force balance during the insertion of the guide member 61 and the mating member 351. This application uses the guide member 61 as a guide post and the mating portion 3513 as a guide groove as an example. The guide portion 613 is connected to the outer wall of the guide body 611. The guide portion 613 and the guide body 611 can be integrally formed, which simplifies the processing of the guide member 61 and increases its structural strength. Alternatively, the guide portion 613 and the guide body 611 can be separately formed. Specifically, the connection method between the guide portion 613 and the guide body 611 can be a detachable connection or a non-detachable connection. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of methods such as gluing, welding, and sintering. In this case, the connection between the guide portion 613 and the guide body 611 is more flexible. The guide portions 613 are evenly distributed around the center of the guide body 611, so that each guide portion 613 experiences uniform force during the insertion of the guide member 61 and the mating member 351. This results in better guiding effect of the guide member 61, and the guide member 61 is less prone to damage, leading to a longer service life for the energy storage robot 100.

[0066] Please refer to Figure 1 and Figure 5In some embodiments, the connector 63 includes a locking portion 631, an elastic portion 633, and a driving portion 635. The locking portion 631 is connected to the elastic portion 633 and is retractable relative to the guide body 611. The elastic portion 633 is disposed within the guide body 611 and provides an elastic force that causes the locking portion 631 to extend at least partially beyond the guide body 611. The driving portion 635 is disposed within the guide body 611 and abuts against the locking portion 631. The driving portion 635 is configured to drive the locking portion 631 back into the guide body 611.

[0067] Specifically, the locking part 631 is a structure in the connector 63 used to lock at least a portion of the structure of the coupling 353, thereby fixing the connector 63 and the coupling 353 together. The elastic part 633 is a device in the connector 63 used to provide an elastic restoring force for the movement of the locking part 631 relative to the guide body 611. The elastic part 633 may be, but is not limited to, a spring or a combination of one or more such as a leaf spring. When the elastic part 633 is a spring, it has the advantages of simple structure and low cost. When the elastic part 633 is a leaf spring, it has the advantage of high load-bearing capacity. One end of the elastic part 633 is connected to the locking part 631, and the other end is connected to the guide body 611 or the drive part 635. In its natural state without force, the elastic part 633 causes the locking part 631 to extend at least partially beyond the guide body 611 to engage with the coupling 353, while the relative position between the connecting assembly 60 and the engaging assembly 35 does not change.

[0068] Please refer to Figure 5 The locking part 631 is provided with a guide surface, and the mating part 351 is a groove capable of accommodating at least a portion of the locking part 631. During the insertion of the guide part 61 and the mating part 351, the guide surface abuts against at least a portion of the structure of the mating part 351, and the locking part 631 is subjected to force and moves towards the guide body 611 ( Figure 5 The elastic part 633 moves and compresses the locking part 631 in the Y1 direction, providing an elastic restoring force away from the guide body 611. After the guide member 61 and the mating member 351 are inserted, the locking part 631 is aligned with the mating member 351, and the locking part 631 has space to move toward the mating member 351. At this time, the elastic restoring force provided by the elastic part 633 causes the locking part 631 to extend relative to the guide body 611, specifically along the Y1 direction. Figure 5 The device moves in the Y2 direction, and the clamping part 631 engages with the mating part 351 to achieve a fixed connection between the energy storage robot 100 and the charging device 300.

[0069] The drive unit 635 is a structure used to drive the locking part 631 to retract into the guide body 611. Specifically, the drive unit 635 includes a drive body 6351 and a drive arm 6353. The drive body 6351 is connected to the drive arm 6353, and the drive body 6351 is used to drive the drive arm 6353 to move in a direction away from the outer wall of the guide body 611 (Y1 direction). Please refer to... Figure 5 The clamping part 631 has a corresponding protruding structure on the side near the drive body 6351, and the drive arm 6353 is connected to the protruding structure. When it is necessary to disconnect the energy storage robot 100 from the charging device 300, the drive body 6351 drives the drive arm 6353 to move away from the outer wall of the guide body 611 (Y1 direction), and the drive arm 6353 drives the clamping part 631 to retract into the guide body 611. The connection between the connector 63 and the mating part 351 is released.

[0070] In summary, the connector 63 can selectively connect or disconnect from the mating part 351 through the cooperation of the clamping part 631, the elastic part 633 and the driving part 635, so as to realize the fixed connection or disconnection between the energy storage robot 100 and the charging device 300, and the charging process of the charging device 300 to the energy storage robot 100 has good stability.

[0071] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the connector 63 is a magnetic element and is disposed on the guide 61. The coupling 353 is a magnetic element, and a magnetic attraction force is generated between the connector 63 and the coupling 353. The magnetic attraction force is used to fix the energy storage robot 100 to the charging device 300.

[0072] Specifically, in some implementations, such as Figure 2 As shown, the connector 63 is disposed at the end of the guide 61, and the coupling 353 is disposed at the bottom of the mating member 351. In this case, the connector 63 and the coupling 353 are opposite each other in the X-direction of the engagement of the guide 61 and the mating member 351, allowing for better engagement. In other embodiments, the connector 63 is disposed on the side of the guide 61, and the coupling 353 is disposed on the side of the mating member 351. In this case, the connector 63 and the coupling 353 are opposite each other in the Y1 direction (Y2 direction) of the guide 61 and the mating member 351, and their engagement can occur during the insertion process of the guide 61 and the mating member 351.

[0073] After the guide 61 and the mating part 351 are inserted, the connector 63 and the mating part 351 are aligned. The magnetic attraction between the connector 63 and the mating part 351 causes them to engage, thus achieving a fixed connection between the energy storage robot 100 and the charging device 300. Therefore, the energy storage robot 100 of this application can be fixedly connected to the charging device 300 through the magnetic attraction between the connector 63 and the mating part 353, and the charging process of the charging device 300 to the energy storage robot 100 has good stability. When the energy storage robot 100 needs to disconnect from the charging device 300 after charging is completed, it is only necessary to activate the moving component 20 to move the body 10 away from the charging device 300, which will disconnect the connection between the connecting component 60 and the mating component 350.

[0074] Understandably, connector 63 plays a role in both the alignment and fixation of the energy storage robot 100 and the charging device 300, thus maximizing the utilization of each structure in the energy storage robot 100. Furthermore, when the energy storage robot 100 needs to be disconnected from the charging device 300, the connection force can be released by changing the polarity of connector 63 or coupling 353.

[0075] Please refer to Figure 6 In some embodiments, the energy storage robot 100 further includes a pressure sensor 83. The pressure sensor 83 is disposed on and protrudes from the outer surface of the guide member 61, and is configured to detect the force applied to the guide member 61. When the force is within a preset pressure range, the moving component 20 stops; when the force exceeds the preset pressure range, the moving component 20 moves the body 10 to bring the force within the preset pressure range.

[0076] Specifically, pressure sensor 83 is a device used to detect the force exerted on at least a portion of the outer wall of guide member 61 during the insertion process of guide member 61 and mating member 351. The magnitude of the force measured by pressure sensor 83 can reflect the alignment of guide member 61 and mating member 351 during the insertion process. For example, if guide member 61 shifts to the left relative to mating member 351, the force on the left outer wall of guide member 61 increases, while the force on the right outer wall of guide member 61 decreases. Pressure sensor 83 is positioned on the outer surface of guide member 61, and it detects the force exerted on the outer wall of guide member 61 corresponding to its position. Therefore, the position of pressure sensor 83 is related to the force it can detect on guide member 61. Thus, pressure sensors 83 are evenly distributed on the outer surface of guide member 61 to more comprehensively reflect the alignment of guide member 61 and mating member 351 during the insertion process. In some embodiments, the pressure sensor 83 protrudes relative to the outer surface of the guide 61, enabling the pressure sensor 83 to detect the force acting on the outer wall of the guide 61 more quickly and sensitively. Of course, in other embodiments, the pressure sensor 83 may be embedded in the guide 61, with both outer surfaces flush.

[0077] The preset pressure range is the reasonable range of force exerted on the outer wall of the guide member 61 when the guide member 61 and the mating member 351 are aligned. The moving component 20 drives the body 10 to move so that the guide member 61 and the mating member 351 can be inserted. When the force is within the preset pressure range, the energy storage robot 100 determines that the guide member 61 and the mating member 351 are aligned, and the moving component 20 stops. When the force exceeds the preset pressure range, the energy storage robot 100 determines that the guide member 61 and the mating member 351 are not aligned. In this case, the energy storage robot 100 needs to control the moving component 20 to move the body 10 according to the specific pressure value. For example, if the guide 61 shifts to the left relative to the mating part 351, the force on the outer wall of the left side of the guide 61 increases and exceeds the pressure range, while the force on the outer wall of the right side of the guide 61 decreases and does not reach the pressure range. At this time, the moving component 20 drives the body 10 to move to the right, the force on the outer wall of the left side of the guide 61 decreases, and the force on the outer wall of the right side of the guide 61 increases. After both enter the pressure range, the energy storage robot 100 determines that the guide 61 and the mating part 351 are aligned, and the moving component 20 stops.

[0078] In summary, the energy storage robot 100 can accurately reflect the force at multiple locations on the outer surface of the guide 61 through the pressure sensor 83 set on the outer surface of the guide 61, so as to accurately analyze the alignment of the guide 61 and the mating part 351 during the insertion process. Then, by controlling the movement of the moving component 20, the insertion direction of the guide 61 and the mating part 351 is adjusted, thereby realizing the alignment of the energy storage robot 100 and the charging device 300.

[0079] In some implementations, the energy storage robot 100 also includes a photovoltaic module (not shown) mounted on the body 10. The photovoltaic module is electrically connected to the battery module 30 and is used to convert light energy into electrical energy to charge the battery module 30. The photovoltaic module may include monocrystalline silicon photovoltaic panels, polycrystalline silicon photovoltaic panels, and thin-film photovoltaic panels, etc. The photovoltaic module can move relative to the body 10 to change its light-receiving area. Specifically, the photovoltaic module includes a retracted state and an extended state. In the retracted state, at least a portion of the photovoltaic module is retracted into the body 10, or attached to the body 10, or otherwise configured to minimize the space occupied. In the extended state, the photovoltaic module is extended, and the light-receiving area of ​​the photovoltaic module is larger than that of the photovoltaic module in the retracted state.

[0080] Please refer to Figure 1 and Figure 2 Secondly, this application provides a charging device 300. The charging device 300 is used to charge the energy storage robot 100 described in any of the above embodiments. The charging device 300 includes a charging body 310, a second charging module 330, and a mating component 350. The second charging module 330 is installed within the charging body 310 and configured to cooperate with a first charging module 40 to charge the energy storage robot 100. The mating component 350 is disposed on the charging body 310 and includes a mating member 351 and a connecting member 353. The mating member 351 is configured to cooperate with a guide member 61, and the connecting member 353 is configured to cooperate with a connector 63, so that the energy storage robot 100 is connected to the charging device 300.

[0081] Specifically, in the above embodiments, the charging device 300 is a device that provides electrical energy to a device with energy storage function. For example, the charging device 300 can provide electrical energy to a new energy vehicle, an energy storage robot 100, or other energy storage devices. This application will describe the charging device 300 providing electrical energy to the energy storage robot 100 as an example. The charging device 300 provides electrical energy to the energy storage robot 100 by charging the battery module 30 in the energy storage robot 100.

[0082] The charging device 300 can charge the energy storage robot 100 via wired or wireless charging. When charging via wired connection, the robot 100 connects to a connector (not shown) on the charging device 300 (e.g., Type 1, Type 2, GB / T, or a custom interface). This method is simple, reliable, and relatively fast. When charging via wireless connection, the first charging module 40 of the robot 100 works in conjunction with the second charging module 330 (described later). The second charging module 330 generates a magnetic field that charges the battery module 30 of the robot 100 through the first charging module 40. At this time, the charging device 300 and the energy storage robot 100 do not need to contact each other, the energy storage robot 100 will not be worn, the energy storage robot 100 has a better appearance and a longer service life. This application takes the charging device 300 charging the energy storage robot 100 through wireless charging as an example.

[0083] The charging body 310 is the main body of the charging device 300, used to house and install other components of the charging device 300 besides the charging body 310 itself. The materials of the charging body 310 include, but are not limited to, metal, plastic, or a combination of both. When the charging body 310 is made of metal, it has high structural strength, is not easily damaged, and provides better protection for other components housed within it, resulting in a long service life for the charging device 300. When the charging body 310 is made of plastic, it is lighter and less expensive, giving the charging device 300 a lightweight advantage.

[0084] The mating component 350 is a component in the charging device 300 that mates with the connecting component 60 of the energy storage robot 100. The mating component 350 is disposed on the outer wall of the charging body 310, specifically at a position corresponding to the connecting component 60 of the energy storage robot 100. The mating member 351 is a structure in the connecting component 60 used to insert into the guide member 61. The insertion method is the same as in the above-described embodiment and will not be repeated here. The connecting member 353 is a structure in the mating component 350 used to further strengthen the connection between the energy storage robot 100 and the charging device 300 after the guide member 61 and the mating member 351 are inserted. The position of the connecting member 353 corresponds to that of the mating member 351; specifically, after the guide member 61 and the mating member 351 are inserted, the connecting member 353 is aligned with the connecting member 63. At this time, the energy storage robot 100 and the charging device 300 are connected by the connector 63 and the coupling 353. The first charging module 40 and the second charging module 330 are aligned and cooperate with each other, and the charging device 300 charges the battery module 30.

[0085] In the charging device 300 of this application, during the process of the energy storage robot 100 replenishing the battery module 30 with electrical energy through the first charging module 40, the energy storage robot 100 is connected to the charging device 300 through the connecting component 60 to achieve an accurate and stable connection between the energy storage robot 100 and the charging device 300. Specifically, the guide 61 on the energy storage robot 100 is inserted into the mating part 351 on the charging device 300, and the connector 63 on the energy storage robot 100 is engaged with the connecting part 353 on the charging device 300. At this time, the energy storage robot 100 and the charging device 300 are precisely aligned, and the first charging module 40 of the energy storage robot 100 and the second charging module 330 of the charging device 300 are precisely matched, resulting in high energy transfer efficiency between the two and high charging efficiency of the energy storage robot 100.

[0086] Please refer to Figure 1 and Figure 2 In some embodiments, the charging body 310 includes a side portion 311, which faces the side wall 11 of the energy storage robot 100 when the energy storage robot 100 is connected to the charging device 300. The second charging module 330 includes a second coil 331 and a second magnetic core 333. The second coil 331 is disposed on the side portion 311 and generates a magnetic field when energized. This magnetic field is used to magnetically induce a magnetic field with the first coil 41 of the first charging module 40. The second magnetic core 333 is disposed on the side portion 311 and shields the second coil 331. The second magnetic core 333 is configured to guide the magnetic field to the second coil 331 and shield the magnetic field from propagating outward from the second magnetic core 333.

[0087] Specifically, when the energy storage robot 100 is connected to the charging device 300 via the connecting component 60, the side portion 311 is the outer wall of the charging body 310 opposite to the energy storage robot 100. As the energy storage robot 100 moves towards the charging device 300, the moving component 20 adjusts the positional relationship between the energy storage robot 100 and the charging device 300 so that the side wall 11 is opposite to the side portion 311. At this time, the side portion 311 is the wall closest to the charging device 300 and the energy storage robot 100. Therefore, placing the second charging module 330 on the side portion 311 allows the first charging module 40 and the second charging module 330 to be closer together, thereby improving energy transfer efficiency.

[0088] The second coil 331 is a structure in the second charging module 330 used to generate a magnetic field. The material of the second coil 331 can be, but is not limited to, copper or aluminum. The second coil 331 is positioned on the upper part of the side portion 311. After the second coil 331 is energized, it generates a magnetic field around it. At this time, the first coil 41 is in this magnetic field and stores the electrical energy converted from the magnetic field energy in the battery module 30. The second magnetic core 333 is a structure in the second charging module 330 used to guide and shield the magnetic field. The second magnetic core 333 is positioned on the side portion 311. Specifically, the second magnetic core 333 is close to the second coil 331 on the side away from the side portion 311 and shields the second coil 331 to separate it from other devices inside the charging device 300. The second magnetic core 333 can guide the magnetic field generated by the charging device 300 to focus it more effectively in the direction of the energy storage robot 100, thereby maximizing the induced current generated by the first coil 41 and improving the efficiency of energy transfer. Meanwhile, the second magnetic core 333 can shield the magnetic field, preventing the magnetic field from propagating outward from the second magnetic core 333 and affecting other devices inside the charging device 300.

[0089] Therefore, the second charging module 330 generates a magnetic field through the second coil 331 to charge the battery module 30 using the first charging module 40. The second coil 331 also works with the second magnetic core 333 to guide and shield the magnetic field. On one hand, the second magnetic core 333 guides the magnetic field and maximizes the induced current generated by the first coil 41, thus providing more electrical energy to the battery module 30 and resulting in high energy transfer efficiency of the energy storage system 1000. On the other hand, the second magnetic core 333 can shield the magnetic field from transmission to other devices inside the charging device 300, protecting these devices and ensuring the charging device 300 operates normally with good safety performance.

[0090] Please refer to Figure 1 and Figure 2 In some embodiments, the mating member 351 includes a mating body 3511 and at least two mating portions 3513. In the mating direction X between the mating member 351 and the guide member 61, the cross-sectional dimension of the mating body 3511, when cut by a plane perpendicular to the mating direction X, gradually decreases. At least two mating portions 3513 are disposed on the inner wall of the mating body 3511 and are evenly distributed around the center of the mating body 3511.

[0091] Specifically, the mating body 3511 is the main body of the mating component 351, and it bears a significant amount of force during the insertion process between the mating component 351 and the guide component 61. The mating body 3511 can be cut into multiple sections by a plane perpendicular to the mating direction X, and the size of each section represents the dimensions of the mating body 3511. Along the mating direction X, the dimensions of the sections gradually decrease, meaning the inner contour dimensions of the mating body 3511 gradually decrease. Therefore, the mating body 3511 provides better guidance during the insertion process with the guide component 61.

[0092] The mating part 3513 is a structure used to further assist the guiding action of the mating body 3511 on the guide body 611. In this case, the structure of the mating part 351 is relatively complex. The mating part 3513 reduces the possibility of misalignment or mis-insertion during the insertion process of the mating part 351 and the guide body 61. There are at least two mating parts 3513 to ensure that the mating parts 351 can achieve force balance during the insertion process. The mating part 3513 is located on the inner wall of the mating body 3511. The mating part 3513 and the mating body 3511 can be a one-piece molding structure, which simplifies the processing of the mating part 351 and increases its structural strength. Alternatively, the mating part 3513 and the mating body 3511 can be a multi-stage molding structure, where the mating body 3511 is formed first, and then the mating part 3513 is machined on the side wall 11 of the mating body 3511. This allows for more flexible processing of the mating part 3513 and the mating body 3511. The mating parts 3513 are evenly distributed around the center of the mating body 3511 so that each mating part 3513 is subjected to uniform force during the insertion of the mating parts 351 and each corresponds to multiple guides 61. The guiding effect of the mating parts 351 is better, and the mating parts 351 are not easily damaged, and the service life of the charging device 300 is longer.
