Description

[0001] This application is a divisional case of the Chinese invention patent with application date of March 4, 2021, application number 202110242098.1, and name “Battery Charging Space, Charging Rack, Charging Room, Battery Swap Station and Battery Swap Control Method”. Technical Field

[0002] The present invention relates to the field of battery replacement, and in particular to a battery charging position, a charging rack, a charging room, a battery replacement station and a battery replacement control method. Background Art

[0003] With the rapid development of new energy in recent years, the energy storage sector has garnered significant attention worldwide, with both electric vehicles and energy storage stations experiencing significant growth. Currently, electric vehicles primarily fall into two categories: direct-charging and quick-swap. Quick-swap vehicles are highly sought after due to their electrification, connectivity, intelligence, and sharing capabilities, addressing current challenges with battery life and battery life. However, quick-swap batteries require access to battery swap stations for rapid battery replacement.

[0004] Currently, battery swap stations primarily consist of a battery swap room and a charging room. Electric vehicles are parked in the battery swap room for battery swapping, and battery swap robots shuttle between the two rooms to swap battery packs between the two vehicles. After the battery packs are removed from the electric vehicle and transported to the charging room, they are moved to a battery transporter. This transporter moves to the corresponding charging bay on the battery rack and then places the battery into the bay, resulting in a relatively complex structure.

[0005] In addition, each charging position on the charging rack can only passively receive and send out batteries, and does not have the ability to actively adjust the position of the battery in the charging position, resulting in high positioning accuracy requirements for the charging position relative to the battery, and high design standards and manufacturing accuracy requirements for the charging position. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art of complex structure of battery transfer devices and high design standards and manufacturing precision requirements for charging positions, and to provide a battery charging position, a charging rack, a charging room, a battery swap station and a battery swap control method.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A battery charging station, comprising a station body, the station body being capable of accommodating a battery pack, the station body having a battery inlet and outlet for the battery pack to enter and exit the station body, the battery charging station further comprising a first belt moving mechanism disposed within the station body, the first belt moving mechanism being configured to carry the battery pack and capable of driving the battery pack to move along a first path, the first path extending from the battery inlet and outlet to a side of the station body away from the battery inlet and outlet;

[0009] The battery charging position further includes a first arrival sensor, the first arrival sensor being used to detect whether the battery pack is located at the first arrival position on the first path;

[0010] The battery charging station further comprises a bearing portion, wherein the bearing portion is located in the station body at a position offset from the first belt moving mechanism;

[0011] The first belt moving mechanism can be raised and lowered relative to the bin body;

[0012] The first arrival sensor can generate a first signal when the battery pack is located at the first arrival position, and the first signal is used to control the first belt moving mechanism to descend until the height of the first belt moving mechanism is lower than the height of the carrying portion.

[0013] This battery charging station utilizes a first belt conveyor mechanism within the station body to transport battery packs between the station body and the battery entrance and exit. This simplifies the structure of the battery transfer device used to access and place battery packs within the station body, while also enabling more precise and controllable positioning of battery packs within the station body. Furthermore, by controlling the start and stop of the first belt conveyor mechanism, precise positioning of various battery pack sizes within the station body can be achieved, making the battery charging station suitable for carrying and / or charging a wide variety of battery pack sizes.

[0014] The first positioning sensor actively monitors the battery pack's position, allowing timely detection of when the battery pack, driven by the first belt moving mechanism, reaches the first positioning point. Furthermore, after the first belt moving mechanism completes its movement of the battery pack, the first belt moving mechanism is lowered relative to the load-bearing portion, ensuring the battery pack remains stationary on the load-bearing portion. This improves the battery pack's positioning accuracy within the battery charging compartment and provides enhanced load stability.

[0015] Preferably, the battery charging position further includes a first stopping mechanism provided in the position body, the first stopping mechanism being located at an end of the first path away from the battery entrance and exit, and the first stopping mechanism being used to stop the battery pack at a first arrival point on the first path.

[0017] Preferably, the first in-position sensor is arranged on the first stopping mechanism.

[0018] In this solution, the above-mentioned structural form is adopted to achieve the purpose of actively monitoring the position of the battery pack through the first in-position sensor, so as to timely obtain the timing when the battery pack reaches the first in-position point driven by the first belt moving mechanism.

[0019] Preferably, the first arrival sensor can generate a first signal when the battery pack is located at the first arrival position, and the first signal is used to control the first belt moving mechanism to stop running.

[0021] Preferably, the battery charging position further comprises a first electrical connector provided in the position body, and when the battery pack is stopped at the first stop position by the first stopping mechanism, the first electrical connector can be electrically connected to the second electrical connector on the battery pack.

[0022] In this solution, the above-mentioned structural form is adopted to provide a more preferred structural setting solution, so that when the battery pack moves to the first arrival position in the battery charging position, the first electrical connector and the second electrical connector on the battery pack can be electrically connected, thereby simplifying the overall control of the battery charging position.

[0023] Preferably, the battery charging position also includes a second stopping mechanism provided in the position body, and the second stopping mechanism is located between the first arrival point and the battery entrance and exit. After the first electrical connector is electrically connected to the second electrical connector, the second stopping mechanism moves to the first path and is used to prevent the battery pack from moving toward the battery entrance and exit.

[0024] In this solution, the aforementioned structure is employed, with the provision of a second stop mechanism, to further enhance the battery charging compartment's ability to position the battery pack. After the second electrical connector on the battery pack is connected to the first electrical connector of the battery charging compartment, the second stop mechanism physically prevents the battery pack from becoming disengaged from the first electrical connector due to external factors, ensuring safe and reliable charging.

[0025] Preferably, the battery charging compartment further comprises a driving mechanism, wherein the driving mechanism and the first electrical connector are both located on a side of the compartment body adjacent to the battery inlet and outlet, and the driving mechanism is connected to the first electrical connector;

[0026] When the battery pack is stopped at the first arrival point by the first stopping mechanism, the driving mechanism can drive the first electrical connector to approach or move away from the battery pack along a second path.

[0027] In this solution, the aforementioned structure is employed, with a drive mechanism configured to actuate and change the position of the first electrical connector, enabling active proximity to the battery pack and electrical connection with the second electrical connector on the battery pack. This electrical connection method is simple and reliable, and by adjusting the drive distance of the drive mechanism, it can be electrically connected to battery packs of varying sizes and specifications, offering excellent compatibility.

[0028] Preferably, the first electrical connector is located on a side of the compartment body adjacent to the battery entrance and exit;

[0029] The battery charging position also includes a second belt moving mechanism provided in the position body, the second belt moving mechanism is used to carry the battery pack and can drive the battery pack to move along a second path, and the second path extends to the first electrical connector in a direction different from the first path.

[0030] In this solution, the above-mentioned structural form is adopted. After the battery pack is moved into the battery charging position by the first belt moving mechanism, the second belt moving mechanism is provided to further move the battery pack to dock with the first electrical connector.

[0031] Preferably, the first belt moving mechanism can be raised relative to the second belt moving mechanism to a height that is higher than that of the second belt moving mechanism;

[0032] The first belt moving mechanism can be lowered relative to the second belt moving mechanism to a height of the first belt moving mechanism lower than that of the second belt moving mechanism.

[0033] In this solution, the above-mentioned structural form is adopted, and the battery pack is switched between moving along the first path and moving along the second path by changing the height of the first belt moving mechanism relative to the second belt moving mechanism. The structure and control are simple, so that after the first belt moving mechanism completes the movement of the battery pack, the second belt moving mechanism can smoothly and reliably drive the battery pack to move.

[0034] Preferably, the first arrival sensor can generate a first signal when the battery pack is located at the first arrival position, and the first signal is used to control the height of the first belt moving mechanism to be lower than that of the second belt moving mechanism.

[0035] In this solution, the above-mentioned structural form is adopted to provide a more preferred lifting control solution for two belt moving mechanisms. The first belt moving mechanism is lowered only after moving the battery pack to the first arrival position, so that the battery pack can be reliably carried on the second belt moving mechanism.

[0036] Preferably, when the battery pack is located at the second arrival point on the second path, the second electrical connector is electrically connected to the first electrical connector;

[0037] The battery charging position further includes a second in-place sensor, which is disposed at one end of the second path close to the first electrical connector, and is used to detect whether the battery pack is located at the second in-place position.

[0038] In this solution, the above-mentioned structural form is adopted to achieve the purpose of actively monitoring the position of the battery pack through the second in-position sensor, so as to timely obtain the timing when the battery pack reaches the second in-position point under the drive of the second belt moving mechanism.

[0039] Preferably, the second arrival sensor can generate a second signal when the battery pack is located at the second arrival position, and the second signal is used to control the second belt moving mechanism to stop running.

[0040] In this solution, the above-mentioned structural form is adopted, and closed-loop control is used to improve the position accuracy of the second belt moving mechanism when driving the battery pack to stop at the first electrical connector for electrical connection, thereby preventing the battery pack from moving too far and causing excessive squeezing on the second electrical connector to damage the second electrical connector.

[0041] Preferably, the battery charging station further comprises a bearing portion, wherein the bearing portion is located in the station body at a position staggered from the first belt moving mechanism and the second belt moving mechanism;

[0042] The first belt moving mechanism can be raised and lowered relative to the bin body;

The first signal is also used to control the first belt moving mechanism to descend until the height of the first belt moving mechanism is lower than the height of the load-bearing portion.

[0044] In this solution, the above-mentioned structural form is adopted to provide a more preferred structural setting solution, so that the battery pack can be stationary after being moved to the first arrival position and be carried on the carrying part, thereby improving the position reliability of the battery pack relative to the battery charging position after it is moved into position within the position body.

[0045] Preferably, the second belt moving mechanism can be raised and lowered relative to the bin body, and the first signal is further used to control the second belt moving mechanism to rise until the height of the second belt moving mechanism is higher than or equal to the height of the bearing portion.

[0046] In this solution, the above-mentioned structural form is adopted to provide a more preferred structural setting solution, so that the battery pack can be carried on the carrying part after being electrically connected, thereby improving the position reliability of the battery pack relative to the battery charging position after it is moved into position within the position body.

[0047] Preferably, the battery charging station further comprises a bearing portion, wherein the bearing portion is located in the station body at a position staggered from the first belt moving mechanism and the second belt moving mechanism along the vertical projection direction;

[0048] The height of the bearing portion is flush with the first belt moving mechanism and the second belt moving mechanism, and the first signal is also used to control the operation of the second belt moving mechanism.

[0049] In this solution, the above-mentioned structural form is adopted, so that the first belt moving mechanism and the second belt moving mechanism can respectively drive the battery pack to move while the load-bearing part bears and shares the weight of the battery pack, and the structure of the battery charging position is relatively simple and the reliability is high.

[0050] Preferably, the battery charging position also includes a second stopping mechanism provided in the position body. After the first electrical connector is electrically connected to the second electrical connector, the second stopping mechanism moves to the second path and is used to prevent the battery pack from moving toward the first arrival point.

[0051] In this solution, the aforementioned structure is employed, with the provision of a second stop mechanism, to further enhance the battery charging compartment's ability to position the battery pack. After the second electrical connector on the battery pack is connected to the first electrical connector of the battery charging compartment, the second stop mechanism physically prevents the battery pack from becoming disengaged from the first electrical connector due to external factors, ensuring safe and reliable charging.

[0052] Preferably, a ball bearing is provided on the upper surface of the bearing portion.

[0053] In this solution, the above-mentioned structural form is adopted to reduce the friction on the surface of the load-bearing part, thereby avoiding large friction between the battery pack and the surface of the load-bearing part when the battery pack moves relative to the compartment body.

[0054] A charging rack comprises the battery charging positions as described above, wherein the battery charging positions are arranged vertically, horizontally or in a vertical and horizontal array.

[0055] The charging rack and each battery charging position thereof are equipped with a first belt moving mechanism in the position body to achieve the purpose of transporting the battery pack between the interior of the position body and the battery entrance and exit, thereby simplifying the structure of the battery transfer device for taking and placing the battery pack relative to the charging rack, and making the position of the battery pack in each position body more accurate and controllable.

[0056] A charging room comprises the charging stand described above.

[0057] The battery charging positions on the charging rack of the charging room are equipped with a first belt moving mechanism in the position body to achieve the purpose of transporting the battery pack between the interior of the position body and the battery entrance and exit, thereby simplifying the structure of the battery transfer device for taking and placing the battery pack relative to the charging room, and making the position of the battery pack in each position body more accurate and controllable.

[0058] Preferably, there are two groups of charging racks, which are symmetrically arranged. A battery transfer device is provided between the two groups of charging racks, and the battery transfer device is used to take and place battery packs relative to the charging racks.

[0059] In this solution, the above-mentioned structural form is adopted to provide a more preferred structural layout, which can maximize the number of batteries that can be carried in the charging rack without increasing the battery transfer device.

[0060] At the same time, since the battery charging positions on each charging rack can send battery packs in or out, the battery transfer device between the two sets of charging racks only needs to meet the purpose of moving battery packs between the battery charging positions, so that the structure of the battery transfer device can also be simplified accordingly.

[0061] A battery swap station, comprising:

[0062] Car loading platform;

[0063] The charging chamber as described above is arranged on one side or both sides of the vehicle loading platform along the direction of travel of the vehicle on the vehicle loading platform;

[0064] A battery replacement device is used to replace the battery pack relative to the vehicle, and the battery replacement device can shuttle between the charging room and the vehicle loading platform.

[0065] In this battery swap station, each battery charging position in the charging room thereof realizes the purpose of transporting the battery pack between the interior of the position body and the battery entrance and exit by setting a first belt moving mechanism in the position body, thereby simplifying the battery transfer device for taking and placing the battery pack relative to the charging room, and making the position of the battery pack in each position body more accurate and controllable, thereby achieving the purpose of simplifying the battery swap station.

[0066] A battery replacement control method, which uses the battery charging position described above, includes:

[0067] Controlling the first belt moving mechanism to drive the battery pack to move along the first path;

[0068] After the battery pack is moved into position along the first path, the first belt moving mechanism is controlled to stop running and / or to descend relative to the storage space body.

[0069] This battery replacement control method moves the battery pack diameter through a first belt moving mechanism set in the warehouse body. Compared with the method of using an external battery transfer device to transport the battery pack, it improves the position of the battery pack in the warehouse body to be more accurate and controllable, and by controlling the start and stop of the first belt moving mechanism, it can achieve precise positioning of various types of battery packs in the warehouse body.

[0070] Preferably, the battery charging station further comprises a first electrical connector disposed in the station body, wherein the first electrical connector is disposed on the first path;

[0071] The step of controlling the first belt moving mechanism to stop running and / or descend relative to the bin body after the battery pack moves into position along the first path includes: controlling the first belt moving mechanism to stop running and / or descend relative to the bin body after the battery pack moves along the first path so that the second electrical connector on the battery pack is electrically connected to the first electrical connector.

[0072] This battery replacement control method uses a first belt moving mechanism to drive the battery pack to move and dock it to the first electrical connector, thereby improving the positioning accuracy and docking reliability of the battery pack with the first electrical connector in the storage unit. In addition, it is only necessary to control the start and stop of the first belt moving mechanism to achieve electrical connection between the first electrical connector and the second electrical connector when various types of battery packs are moved into position in the storage unit.

[0073] Preferably, the battery charging station further comprises a first electrical connector and a drive mechanism provided in the station body, the drive mechanism being connected to the first electrical connector, and the battery replacement control method further comprises:

[0074] When the battery pack moves to a position along the first path, the driving mechanism is further controlled to drive the first electrical connector close to the battery pack, so that the first electrical connector is electrically connected to the second electrical connector on the battery pack.

[0075] This battery replacement control method improves the positioning accuracy and docking reliability of the battery pack with the first electrical connector in the bin body by driving the first electrical connector close to the battery pack through a driving mechanism, and provides more options for the installation of the first electrical connector in the bin body to adapt to bin bodies in various spaces and improve applicability.

[0076] Preferably, the battery charging station further comprises a first electrical connector and a second belt moving mechanism provided in the station body, wherein the first electrical connector is configured to be electrically connected to a second electrical connector on the battery pack, and the second belt moving mechanism is used to carry the battery pack and to drive the battery pack to move along a second path, wherein the second path extends to the first electrical connector in a direction different from the first path, and the battery replacement control method further comprises:

[0077] After the battery pack is moved into position along the first path, controlling the second belt moving mechanism to carry the battery pack and drive the battery pack to move along the second path;

[0078] When the battery pack moves along the second path so that the second electrical connector is electrically connected to the first electrical connector, the second belt moving mechanism is controlled to stop running and / or to descend relative to the bin body.

[0079] This battery replacement control method moves the battery pack along different paths by simultaneously setting a first belt moving mechanism and a second belt moving mechanism in the bin body. Compared with the method of using an external battery transfer device to transport the battery pack, it improves the position accuracy and docking reliability of the battery pack with the first electrical connector in the bin body, and is particularly suitable for the situation where the first electrical connector is installed on the adjacent side of the battery entrance and exit of the bin body.

[0080] Preferably, the battery charging position further includes a second stop mechanism that is liftably disposed within the position body, the second stop mechanism being disposed on a side opposite to and away from the first electrical connector. The battery replacement control method further includes:

[0081] When the second electrical connector on the battery pack is electrically connected to the first electrical connector, the second stopping mechanism is controlled to rise relative to the bin body to prevent the battery pack from retreating in a direction away from the first electrical connector.

[0082] This battery replacement control method improves the limiting ability of the battery pack by controlling the second stop mechanism to rise relative to the compartment body after the battery pack is docked to the first electrical connector, so as to avoid the battery pack from accidentally disengaging from the first electrical connector due to external force factors, thereby ensuring continuous charging.

[0083] The positive progress effect of the present invention is:

[0084] The battery charging position, charging rack, charging room, battery swap station and battery swap control method achieve the purpose of transporting battery packs between the interior of the position body and the battery entrance and exit by setting a first belt moving mechanism in the position body, so as to simplify the battery transfer device for taking and placing battery packs relative to the battery charging position, and make the position of the battery pack in the position body more accurate and controllable.

[0111] Battery Pack 20 DETAILED DESCRIPTION

[0112] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0113] Example 1

[0114] The present invention provides a battery swap station, which includes a vehicle loading platform 100, a charging room 200 and a battery swap device (not shown in the figure). Figure 1 As shown, the vehicle loading platform 100 is used for the vehicle 300 to enter and park. There are two charging rooms 200 in the battery swap station in this embodiment, which are distributed on both sides of the vehicle loading platform 100. The battery swap equipment can shuttle between the two charging rooms 200 and the vehicle loading platform 100. It is used to dismantle the low-power battery pack 20 on the vehicle 300 and transport the low-power battery pack 20 to the charging room 200 for charging. It is also used to transport the battery pack 20 that has completed charging in the charging room 200 to the battery swap point of the vehicle loading platform 100, and install the fully charged battery pack 20 on the vehicle 300.

[0115] like Figure 2As shown, the charging room 200 in this embodiment includes two groups of charging racks 201. The two groups of charging racks 201 are arranged symmetrically. A battery transfer device 202 is provided between the two groups of charging racks 201. After the battery transfer device 202 obtains the depleted battery pack 20 from the battery exchange equipment, it moves the battery pack 20 to the corresponding position of the charging rack 201 by ascending, or takes out the fully charged battery pack 20 from the corresponding position of the charging rack 201, and then delivers the battery pack 20 to the battery exchange equipment. This structural layout increases the corresponding number of battery transfer devices 202 and battery charging positions 10 on the charging rack 201 as much as possible without increasing the number of battery transfer devices 202, thereby increasing the number of battery packs 20 that can be carried in the charging rack 201. Among them, the charging rack 201 includes a plurality of battery charging positions 10 arranged in an array along the vertical direction.

[0116] The specific structure of the battery charging position 10 is as follows Figure 3 As shown, it comprises a storage unit 1, a first belt moving mechanism 2, and a load-bearing portion 3. The storage unit 1 is used to accommodate a battery pack 20. A battery access port 11 is provided at one end of the storage unit 1, near the battery transporter 202, for moving the battery pack 20 in and out. The lower surface of the storage unit 1 is provided with a base plate 12, upon which both the first belt moving mechanism 2 and the load-bearing portion 3 are mounted. In other embodiments, the lower surface of the storage unit 1 may not have a base plate 12, and a frame structure capable of supporting the first belt moving mechanism 2 and the load-bearing portion 3 may be provided.

[0117] The first belt moving mechanism 2 is composed of two rows of pulleys. The belts on the pulleys are used to carry the battery packs 20 and can drive the battery packs 20 to move within the storage body 1 through the rotation of the driving pulley of the first belt moving mechanism 2. The path along which the battery packs 20 are moved by the first belt moving mechanism 2 is a first path A. The first path A extends from the battery entrance 11 to the side of the storage body 1 away from the battery entrance 11. This is to achieve the purpose of transporting the battery packs 20 between the interior of the storage body 1 and the battery entrance 11 through the drive of the first belt moving mechanism 2. Because the battery charging storage body 10 has the function of moving the battery packs 20 from the battery entrance 11 into the storage body 1 and removing the battery packs 20 from the storage body 1 out of the battery entrance 11, the corresponding battery transporter 202 no longer needs to be provided with a cantilever extension structure such as a double extension mechanism for picking up and placing the battery packs 20, thereby simplifying the structure of the battery transporter 202. The first belt moving mechanism 2 can also be used to adjust the position of the battery pack 20 within the storage compartment body 1. This arrangement also allows for more precise and controllable positioning of the battery pack 20 within the storage compartment body 1. Furthermore, by controlling the start and stop of the first belt moving mechanism 2, precise positioning of various battery packs 20 within the storage compartment body 1 can be achieved, making the battery charging compartment 10 suitable for carrying a variety of battery packs 20.

[0118] The carrying portion 3 is distributed on both sides or in the middle of the first belt moving mechanism 2 along the width direction of the battery pack 20 so as to be staggered with the first belt moving mechanism 2. The function of the carrying portion 3 is to carry the battery pack 20 to share the weight of the battery pack 20 carried by the first belt moving mechanism 2.

[0119] In this embodiment, Figure 5 and Figure 6 As shown, the first belt moving mechanism 2 can be raised and lowered relative to the load-bearing portion 3. When the first belt moving mechanism 2 moves the battery pack 20, the height of the first belt moving mechanism 2 will be higher than the load-bearing portion 3, preventing the bottom of the battery pack 20 from rubbing against the load-bearing portion 3 and generating large resistance. After the battery pack 20 is moved into position, the height of the first belt moving mechanism 2 will be lower than the load-bearing portion 3, so that the majority of the weight of the battery pack 20 acts directly on the load-bearing portion 3, preventing the first belt moving mechanism 2 from bearing the weight of the battery pack 20 for a long time, thereby improving the durability of the first belt moving mechanism 2. At the same time, placing the battery pack 20 on the load-bearing portion 3 can also improve the positioning reliability of the battery pack 20 relative to the battery charging compartment 10. In other embodiments, if the various disadvantages caused by the first belt moving mechanism 2 carrying the battery pack 20 for a long time are not considered, the load-bearing portion 3 can also be omitted.

[0120] Among them, how the first belt moving mechanism 2 adjusts its height relative to the load-bearing part 3 is achieved in this embodiment by driving the first belt moving mechanism 2 to rise and fall as a whole through a lifting drive mechanism. The specific structure of the lifting drive mechanism can be referred to the existing technology, so it will not be described in detail here.

[0121] like Figure 4 As shown, the battery charging station 10 also includes a first stopping mechanism 71 and a first arrival sensor (not shown). The first stopping mechanism 71 is also located on the bottom plate 12 of the station body 1. It is specifically positioned along the first path A, away from the battery access port 11. The first stopping mechanism 71 functions to stop the battery pack 20 at the first arrival point along the first path A, physically securing the battery pack 20 at the predetermined arrival point. This structure is simple and reliable. In this embodiment, the first stopping mechanism 71 can be positioned below the bottom surface of the battery pack 20 when in the non-stopping state. When the battery pack 20 is to be stopped, the first stopping mechanism 71 rises to a height above the bottom surface of the battery pack 20, achieving physical retention and ensuring the battery pack 20 is precisely stopped at the first arrival point. In other embodiments, the height of the first stopping mechanism 71 can be set to a fixed position, i.e., maintained in the stopping state. In this case, the first stopping mechanism 71 is always above the bottom surface of the battery pack 20.

[0122] The first in-position sensor is provided on the first stopping mechanism 71. The first in-position sensor is used to detect whether the battery pack 20 is located at the first in-position position. The first in-position sensor is used to actively monitor the position of the battery pack 20 so as to timely obtain the timing when the battery pack 20 reaches the first in-position position under the drive of the first belt moving mechanism 2, thereby improving the control accuracy. Specifically, the first in-position sensor can generate a first signal when the battery pack 20 is located at the first in-position position. The first signal is transmitted to the control motor of the first belt movement through a wire, causing the first belt moving mechanism 2 to stop running. Through this closed-loop control method, the accuracy of the first belt moving mechanism 2 in driving the battery pack 20 to stop at the first in-position position can be improved, and a high degree of automation can be achieved. Among them, the first in-position sensor preferably adopts a non-contact induction sensor to avoid hindering the normal movement of the battery pack 20.

[0123] The battery charging position 10 also includes a first electrical connector 4, which is arranged on the position body 1. Its function is to dock with the second electrical connector on the battery pack 20 to enable the battery charging position 10 to charge the battery pack 20.

[0124] In this embodiment, Figure 3As shown, the first electrical connector 4 is arranged on the back side of the battery charging compartment 10, that is, the side away from the battery inlet and outlet 11, and the number of the first stopping mechanisms 71 is two, respectively distributed on the left and right sides of the first electrical connector 4. When the battery pack 20 is moved to the first arrival point driven by the first belt moving mechanism 2, the first electrical connector 4 can be electrically connected to the second electrical connector on the battery pack 20. In this embodiment, a second stopping mechanism 72 can also be provided in the compartment body 1. The second stopping mechanism 72 is specifically located between the first arrival point and the battery inlet and outlet 11. When the first electrical connector 4 is electrically connected to the second electrical connector, the second stopping mechanism 72 moves to the first path A to prevent the battery pack 20 from moving toward the battery inlet and outlet, that is, it plays the role of stopping the battery pack 20 from retreating. In this embodiment, the height of the second stopping mechanism 72 in the non-stop state needs to be lower than the bottom surface of the battery pack 20. When the battery pack 20 needs to be stopped, the second stopping mechanism 72 rises so that its height is higher than the bottom surface of the battery pack 20, thereby achieving the purpose of physical limitation and preventing the battery pack 20 from escaping from the storage space body 1.

[0125] In other embodiments, the battery charging compartment 10 can be adapted to accommodate and charge multiple battery pack sizes. The term "multiple battery pack sizes" refers to battery packs of varying lengths, widths, and heights. In this case, the second stop mechanism 72 can further move along the first path A, so that after the second stop mechanism 72 is raised, the multiple battery pack sizes can be physically positioned.

[0126] On this basis, this embodiment provides a battery replacement control method corresponding to the structure of the above-mentioned battery charging compartment 10, which specifically includes the following steps:

[0127] S11 , controlling the first belt moving mechanism 2 to start, so that the battery pack 20 carried on its surface moves along the first path A and enters the battery charging compartment 10 .

[0128] S12 . When the battery pack 20 moves along the first path A until the second electrical connector on the battery pack 20 is electrically connected to the first electrical connector 4 , the first belt moving mechanism 2 is controlled to stop running.

[0129] S13 . After the second electrical connector on the battery pack is electrically connected to the first electrical connector 4 , the second stopping mechanism is controlled to rise relative to the compartment body to prevent the battery pack from retreating in a direction away from the first electrical connector 4 .

[0130] The above-mentioned battery replacement control method moves the battery pack 20 radially through the first belt moving mechanism 2 set in the bin body 1, driving the battery pack 20 to move and dock to the first electrical connector 4, thereby improving the position accuracy and docking reliability of the battery pack 20 and the first electrical connector 4 in the bin body 1, and only needs to control the start and stop of the first belt moving mechanism 2 to achieve the purpose of electrically connecting the first electrical connector 4 with the second electrical connector on the battery pack 20 when various models of battery packs 20 are moved into place in the bin body 1.

[0131] To ensure the positioning effect of the first electrical connector 4 and the second electrical connector, after the first belt moving mechanism 2 drives the battery pack 20 to move so that the second electrical connector of the battery pack 20 is docked with the first electrical connector 4 of the battery charging compartment 10, the second stopping mechanism 72 is used to physically limit the battery pack 20 so that the first electrical connector 4 is precisely stopped and kept in close position with the second electrical connector to prevent the battery pack 20 from moving too far and excessively squeezing the first electrical connector 4, thereby damaging the first electrical connector 4 and / or the second electrical connector.

[0132] In addition, the second stop mechanism 72 can prevent the battery pack 20 from moving toward the battery inlet and outlet 11 and from leaving the compartment body 1 or causing the electrical connection to fail. In this embodiment, the second stop mechanism 72 is used to position the battery pack 20. Figure 7 As shown in the figure, it can be seen that the second stopping mechanism 72 contacts the battery pack 20 through the inclined surface 7a, so that during the rising process of the second stopping mechanism 72, it can also generate a force to drive the battery pack 20 to be pressed toward the first electrical connector 4, thereby improving the electrical connection effect of the battery pack 20.

[0133] In addition, after the first belt moving mechanism 2 drives the battery pack 20 to move to the position, the first belt moving mechanism 1 can also be relatively lowered so that the battery pack 20 is completely carried on the carrying portion 3 and maintained at the first arrival position.

[0134] Example 2

[0135] This embodiment also provides a battery charging compartment, the structure of which is substantially the same as that of the battery charging compartment provided in embodiment 1, except that: Figure 8 and Figure 9 As shown, in this embodiment, the first electrical connector 4 is disposed on a side of the compartment body 1 adjacent to the battery access port 11. Therefore, the first belt moving mechanism 2 cannot move the battery pack 20 so that the second electrical connector on the battery pack 20 can be directly connected to the first electrical connector 4.

[0136] The battery charging bin in this embodiment also includes a second belt moving mechanism 5 provided on the bottom plate 12 of the bin body 1. The extension direction of the second belt moving mechanism 5 is perpendicular to that of the first belt moving mechanism 2. The second belt moving mechanism 5 is provided between the two groups of pulleys of the first belt moving mechanism 2 to achieve the purpose of staggered arrangement with the first belt moving mechanism 2. The second belt moving mechanism 5 is used to carry the battery pack 20 and can drive the battery pack 20 to move along the second path B. As can be seen from the figure, the second path B in this embodiment is perpendicular to the first path A and extends to the location of the first electrical connector 4. Through this structural setting, after the battery pack 20 is moved into the first arrival point of the battery charging bin 10 by the first belt moving mechanism 2, the battery pack 20 is further moved along the second path B by the provided second belt moving mechanism 5 until it is docked with the first electrical connector 4 to achieve the charging purpose.

[0137] Specifically, to enable both the first and second belt moving mechanisms 2 and 5 to drive the battery pack 20, the belt surfaces of the first and second belt moving mechanisms 2 and 5 can be located at the same height, but higher than the load-bearing portion 3. Alternatively, the belt surfaces of the first and second belt moving mechanisms 2 and 5, as well as the load-bearing portion 3, can all be located at the same height. In this case, to reduce friction on the surface of the load-bearing portion 3 and prevent significant friction between the battery pack 20 and the load-bearing portion 3 when driven by the first or second belt moving mechanism 2 and 5, a ball bearing is provided on the upper surface of the load-bearing portion 3.

[0138] This embodiment provides a relative lifting solution: the first belt moving mechanism 2 can be lifted and lowered relative to the second belt moving mechanism 5. When the first belt moving mechanism 2 drives the battery pack 20 to move, the height of the first belt moving mechanism 2 will be higher than the second belt moving mechanism 5 to avoid the bottom of the battery pack 20 rubbing against the belt surface of the second belt moving mechanism 5 and generating greater resistance. After the battery pack 20 moves to the first arrival position, the height of the first belt moving mechanism 2 will be lower than the second belt moving mechanism 5, so that the battery pack 20 is carried by the second belt moving mechanism 5, so that the second belt moving mechanism 5 can drive the battery pack 20 to move along the second path B.

[0139] In this embodiment, the height adjustment of the first belt moving mechanism 2 relative to the second belt moving mechanism 5 is achieved by a lifting drive mechanism that drives the first belt moving mechanism 2 upward and downward as a whole. The specific structure of the lifting drive mechanism can be found in the prior art and will not be described in detail here. Of course, the lifting drive mechanism can also be installed on the second belt moving mechanism 5 to enable the second belt moving mechanism 5 to be raised and lowered relative to the first belt moving mechanism 2.

[0140] In other embodiments, the battery charging position 10 may be suitable for carrying and / or charging various types of battery packs. The so-called various types of battery packs refer to battery packs of different types that may have different lengths, widths, and heights. At this time, the second stop mechanism 72 may also move along the first path A, so that after the second stop mechanism 72 rises, physical limitation of various types of battery packs can be achieved.

[0141] On this basis, this embodiment also provides a battery replacement control method corresponding to the structure of the above-mentioned battery charging compartment 10, which specifically includes the following steps:

[0142] S21 , controlling the first belt moving mechanism 2 to start, so that the battery pack 20 carried on its surface moves along the first path A and enters the battery charging compartment 10 .

[0143] S22 . After the battery pack 20 moves to its position along the first path A, the first belt moving mechanism 2 is controlled to stop running, and the second belt moving mechanism 5 is controlled to carry the battery pack 20 and drive the battery pack 20 to move along the second path B.

[0144] S23 . After the battery pack 20 moves along the second path B and the second electrical connector is electrically connected to the first electrical connector 4 , the second belt moving mechanism 5 is controlled to stop running.

[0145] The above-mentioned battery replacement control method moves the battery pack 20 along different paths by simultaneously setting a first belt moving mechanism 2 and a second belt moving mechanism 5 in the bin body 1, driving the battery pack 20 to move and dock to the first electrical connector 4, thereby improving the position accuracy and docking reliability of the battery pack 20 in the bin body 1 and the first electrical connector 4, and is particularly suitable for the situation where the first electrical connector 4 is installed on the adjacent side of the battery entrance and exit 11 of the bin body 1.

[0146] The stopping mechanism in this embodiment includes a first stopping mechanism 71 and a second stopping mechanism 72. The layout of the two stopping mechanisms on the bottom plate 12 is as follows: Figure 8 As shown: the first stopping mechanism 71 is provided on the first path A, and its purpose is to stop the battery pack 20 at the first arrival point along the first path A. The second stopping mechanism 72 is provided on the second path B. After the first electrical connector 4 and the second electrical connector are in contact and electrically connected, the second stopping mechanism 72 moves to the second path B and is used to stop the battery pack 20 from moving in a direction away from the first electrical connector 4. The purpose of providing the second stopping mechanism 72 is to improve the reliability of the positioning and electrical connection of the battery pack 20 after the battery pack 20 is docked with the first electrical connector 4 along the second path B. The specific structures of the first stopping mechanism 71 and the second stopping mechanism 72 can refer to the structures provided by the first stopping mechanism 71 and the second stopping mechanism 72 in Example 1.

[0147] In this embodiment, the first in-position sensor is disposed on the first stop mechanism and generates a first signal when the battery pack 20 is at the first in-position position. This first signal is used to control the first belt moving mechanism 2 to stop, or to control the first belt moving mechanism 2 to be lower than the second belt moving mechanism 5, or to perform both actions simultaneously. The first signal is used as a basis for controlling the start and stop of the first belt moving mechanism 2, or to control its elevation relative to the second belt moving mechanism 5, so that the battery pack 20 can be reliably carried on the second belt moving mechanism 5, achieving the purpose of precise control.

[0148] This first signal also serves as a basis for driving the second belt moving mechanism 5 to rise relative to the first belt moving mechanism 2. After the first in-position sensor generates the first signal, the second belt moving mechanism 5 rises, allowing the battery pack 20 to be carried on the second belt moving mechanism 5, and the second belt moving mechanism 5 is activated to move the battery pack 20.

[0149] In this embodiment, the battery charging station 10 also includes a second in-position sensor (not shown). The second in-position sensor is positioned at one end of the second path B near the first electrical connector 4. The second in-position sensor detects whether the battery pack 20 is at the second in-position position. This second in-position sensor actively monitors the position of the battery pack 20, allowing timely detection of the timing when the battery pack 20 reaches the second in-position position under the drive of the second belt moving mechanism 5, thereby achieving precise control. Specifically, the second in-position sensor generates a second signal when the battery pack 20 is at the second in-position position. This second signal is used to control the second belt moving mechanism 5 to stop operation, thereby promptly stopping the operation of the second belt moving mechanism 5 after the battery pack 20 is moved into position. Through closed-loop control, the position accuracy of the second belt moving mechanism 5 when driving the battery pack 20 to stop at the point of electrical connection with the first electrical connector 4 is improved, preventing the battery pack 20 from excessively squeezing and damaging the second electrical connector after over-movement.

[0150] Example 3

[0151] This embodiment also provides a battery charging compartment, the structure of which is substantially the same as that of the battery charging compartment provided in embodiment 2, except that: Figure 10 and Figure 11 As shown, the battery charging compartment in this embodiment does not have a second belt moving mechanism 5. The battery charging compartment includes a driving mechanism 6, which is also arranged on the side of the compartment body 1 adjacent to the battery entrance and exit 11 and is connected to the first electrical connector 4. The driving mechanism 6 is a linear motion mechanism, which is used to drive the first electrical connector 4 to move in a direction away from or close to the battery pack 20.

[0152] After the battery pack 20 is stopped at the first arrival point by the first stopping mechanism 71, the driving mechanism 6 can drive the first electrical connector 4 to move along the second path B as in Example 2 toward or away from the battery pack 20, thereby replacing the second belt moving mechanism 5, and actively moving the first electrical connector 4 to achieve the purpose of approaching and electrically connecting to the second electrical connector on the battery pack 20.

[0153] In this embodiment, a second stopping mechanism 72 is also provided for supporting the battery pack 20 along the second path B, thereby improving the reliability of the connection between the battery pack 20 and the first electrical connector 4 .

[0154] With the above-described structure, the drive mechanism 6 is provided to drive and change the position of the first electrical connector 4, thereby actively approaching the battery pack 20 and electrically connecting with the second electrical connector on the battery pack 20. This electrical connection method is simple and reliable, and by adjusting the driving distance of the drive mechanism 6, it can meet the purpose of electrically connecting with battery packs 20 of different models and specifications, and has good compatibility.

[0155] On this basis, this embodiment also provides a battery replacement control method corresponding to the structure of the above-mentioned battery charging compartment 10, which specifically includes the following steps:

[0156] S31 , controlling the first belt moving mechanism 2 to start, so that the battery pack 20 carried on its surface moves along the first path A and enters the battery charging compartment 10 .

[0157] S32. After the battery pack 20 moves to its position along the first path A, the first belt moving mechanism 2 is controlled to stop running, and the driving mechanism 6 is controlled to drive the first electrical connector 4 close to the battery pack 20 so that the first electrical connector 4 is electrically connected to the second electrical connector on the battery pack 20.

[0158] This battery replacement control method improves the positioning accuracy and docking reliability of the battery pack 20 with the first electrical connector 4 in the bin body 1 by controlling the driving mechanism 6 to drive the first electrical connector 4 close to the battery pack 20. In addition, this solution of actively controlling the movement of the first electrical connector 4 to achieve docking provides more options for the installation of the first electrical connector 4 in the bin body 1, so as to adapt to bin bodies 1 in various spaces and improve applicability.
