Description

[0001] This application is a division of a Chinese invention patent with an 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 field has received attention from all over the world. Both electric vehicles and energy storage stations have made great progress. At present, electric vehicles mainly include direct charging and quick-change types. Among them, the quick-change type is highly sought after because of its characteristics of electrification, networking, intelligence and sharing, which solves the current problems of electric vehicle charging endurance and battery life. However, the quick-change type requires the help of a battery swap station to achieve rapid battery replacement.

[0004] At present, battery swap stations mainly include battery swap rooms and charging rooms. Electric vehicles are parked in the battery swap rooms for battery swapping, and battery swap robots shuttle between the battery swap rooms and the charging rooms to achieve battery pack replacement between the battery swap rooms and electric vehicles. After the battery packs removed from the electric vehicle are transported to the charging room, the batteries will be transported to the battery transport device, which can move to the corresponding charging position on the battery rack and then place the batteries into the position, which makes the structure of the battery transport device more complicated.

[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, which in turn requires high design standards and manufacturing accuracy for the charging position.

[0025] 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 bearing portion.

[0026] In the present solution, the above-mentioned structural form is adopted. After the first belt moving mechanism completes the movement of the battery pack, the battery pack is statically carried on the carrying part by relatively lowering the first belt moving mechanism, thereby improving the positioning accuracy of the battery pack in the battery charging position and improving the carrying stability.

[0032] In the present 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.

[0033] 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.

[0034] 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 the battery pack is moved to the first arrival position, so that the battery pack can be reliably carried on the second belt moving mechanism.

[0035] 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;

[0036] The battery charging position also includes a second in-place sensor, which is disposed at one end of the second path close to the first electrical connector, and the second in-place sensor is used to detect whether the battery pack is located at the second in-place position.

[0037] 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.

[0038] Preferably, the second in-position sensor can generate a second signal when the battery pack is located at the second in-position position, and the second signal is used to control the second belt moving mechanism to stop running.

[0039] In the present solution, the above-mentioned structural form is adopted to improve the position accuracy of the second belt moving mechanism when driving the battery pack to stop at the electrical connection with the first electrical connector through closed-loop control, so as to prevent the battery pack from over-squeezing the second electrical connector and damaging the second electrical connector after moving too far.

[0044] 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.

[0045] 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.

After the second electrical connector on the battery pack is connected to the first electrical connector of the battery charging position, the second stop mechanism prevents the battery pack from being disengaged from the first electrical connector due to external factors through physical limiting, thereby ensuring charging safety and reliability.

[0051] Preferably, a ball bearing is provided on the upper surface of the bearing portion.

[0052] In this solution, the above-mentioned structural form is adopted to reduce the friction force 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.

[0053] A charging rack comprises the battery charging positions as described above, wherein the battery charging positions are arranged vertically, horizontally or in a horizontal and vertical array.

[0055] A charging room comprises the charging stand as described above.

[0056] 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, so as to simplify the structure of the battery transfer device for taking and placing the battery pack relative to the charging room, and make the position of the battery pack in each position body more accurate and controllable.

[0057] Preferably, there are two groups of charging racks, which are symmetrically arranged, and 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.

[0058] 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.

[0059] 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 groups 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.

[0060] A battery swap station, comprising:

[0061] Car loading platform;

[0062] The charging room as described above is arranged on one side or both sides of the vehicle carrying platform along the driving direction of the vehicle on the vehicle carrying platform;

[0063] A battery replacement device, wherein the 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.

[0064] In the 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, so as to simplify the battery transfer device for taking and placing the battery pack relative to the charging room, and make the position of the battery pack in each position body more accurate and controllable, thereby realizing the purpose of simplifying the battery swap station.

[0065] A battery replacement control method, which uses the battery charging position as described above, and the battery replacement control method includes:

[0066] Controlling the first belt moving mechanism to drive the battery pack to move along the first path;

[0067] 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.

[0068] The battery replacement control method moves the battery pack diameter by a first belt moving mechanism disposed in the storage body. Compared with the method of transporting the battery pack by an external battery transfer device, the position of the battery pack in the storage body is more accurate and controllable, and by controlling the start and stop of the first belt moving mechanism, various types of battery packs can be accurately positioned in the storage body.

[0069] Preferably, the battery charging compartment further comprises a first electrical connector disposed in the compartment body, and the first electrical connector is disposed on a first path;

[0070] The step of controlling the first belt moving mechanism to stop running and / or to 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 to descend relative to the bin body after the battery pack moves along the first path to the point where the second electrical connector on the battery pack is electrically connected to the first electrical connector.

[0071] The battery replacement control method drives the battery pack to move and dock with the first electrical connector through the first belt moving mechanism, thereby improving the positioning accuracy and docking reliability of the battery pack with the first electrical connector in the storage space body, and only needs 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 place in the storage space body.

[0072] Preferably, the battery charging position further comprises a first electrical connector and a driving mechanism disposed in the position body, the driving mechanism being connected to the first electrical connector, and the battery replacement control method further comprises:

[0073] When the battery pack moves to a position along the first path, the driving mechanism is controlled to drive the first electrical connector to approach the battery pack, so that the first electrical connector is electrically connected to the second electrical connector on the battery pack.

[0074] The battery replacement control method improves the positioning accuracy and docking reliability of the battery pack with the first electrical connector in the storage compartment 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 storage compartment body to adapt to storage compartment bodies in various spaces and improve applicability.

[0075] Preferably, the battery charging position further comprises a first electrical connector and a second belt moving mechanism provided in the position body, the first electrical connector being configured to be electrically connected to a second electrical connector on the battery pack, the second belt moving mechanism being used to carry the battery pack and to drive the battery pack to move along a second path, the second path extending to the first electrical connector in a direction different from the first path, and the battery replacement control method further comprises:

[0076] When the battery pack moves to a 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;

[0077] When the battery pack moves along the second path to electrically connect the second electrical connector to the first electrical connector, the second belt moving mechanism is controlled to stop running and / or to descend relative to the bin body.

[0078] The battery replacement control method moves the battery pack along different paths by simultaneously arranging a first belt moving mechanism and a second belt moving mechanism in the bin body. Compared with the method of transporting the battery pack using an external battery transport device, the positioning accuracy and docking reliability of the battery pack with the first electrical connector in the bin body are improved, and the method 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.

[0079] Preferably, the battery charging position further comprises a second stop mechanism which is liftably arranged in the position body, and the second stop mechanism is arranged on a side opposite to and away from the first electrical connector. The battery replacement control method further comprises:

[0080] 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.

[0081] 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.

[0082] The positive and progressive effects of the present invention are:

[0083] The battery charging bin, charging rack, charging room, battery swap station and battery swap control method achieve the purpose of transporting battery packs between the interior of the bin body and the battery entrance and exit by setting a first belt moving mechanism in the bin body, so as to simplify the battery transfer device for taking and placing the battery pack relative to the battery charging bin and make the position of the battery pack in the bin body more accurate and controllable.

[0110] Battery Pack 20 DETAILED DESCRIPTION

[0111] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0112] Example 1

[0113] 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 respectively 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, and 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 fully charged battery pack 20 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.

[0114] like Figure 2As shown, the charging room 200 in this embodiment includes two groups of charging racks 201, which 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 low-power battery pack 20 from the battery exchange device, 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 device. 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.

[0115] The specific structure of the battery charging compartment 10 is as follows Figure 3 As shown, it includes a bin body 1, a first belt moving mechanism 2 and a bearing part 3. The bin body 1 is used to accommodate the battery pack 20. A battery entrance and exit 11 is provided at one end of the bin body 1 close to the battery transport device 202 for the battery pack 20 to be moved in or out. A bottom plate 12 is provided on the lower surface of the bin body 1, and the first belt moving mechanism 2 and the bearing part 3 are both arranged on the bottom plate 12. In other embodiments, the bottom plate 12 may not be provided on the lower surface of the bin body 1, as long as a frame structure corresponding to the first belt moving mechanism 2 and the bearing part 3 is provided.

[0116] The first belt moving mechanism 2 is composed of two rows of pulleys. The belts on the pulleys are used to carry the battery pack 20 and can drive the battery pack 20 to move in the bin body 1 through the rotation of the driving wheel of the first belt moving mechanism 2. The path for the battery pack 20 to move through the first belt moving mechanism 2 is the first path A. The first path A extends from the battery entrance 11 to the side of the bin body 1 away from the battery entrance 11, so as to achieve the purpose of transporting the battery pack 20 between the inside of the bin body 1 and the battery entrance 11 through the drive of the first belt moving mechanism 2. Since the battery charging bin 10 has the function of moving the battery pack 20 from the battery entrance 11 into the bin body 1 and moving the battery pack 20 in the bin body 1 out of the battery entrance 11, the corresponding battery transport device 202 does not need to be provided with a cantilever extension structure such as a double extension mechanism for taking and placing the battery pack 20, thereby simplifying the structure of the battery transport device 202. At the same time, the position of the battery pack 20 in the bin body 1 can be adjusted by the first belt moving mechanism 2, and the setting of the first belt moving mechanism 2 also makes the positioning of the battery pack 20 in the bin body 1 more accurate and controllable. At the same time, by controlling the start and stop of the first belt moving mechanism 2, the accurate positioning of various types of battery packs 20 in the bin body 1 can be achieved, so that the battery charging bin 10 can be suitable for carrying various types of battery packs 20.

[0117] The bearing part 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 bearing part 3 is used to bear the battery pack 20 to share the weight of the battery pack 20 carried by the first belt moving mechanism 2 .

[0118] In this embodiment, Figure 5 and Figure 6 As shown, the first belt moving mechanism 2 can be raised and lowered relative to the bearing part 3. 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 bearing part 3 to avoid the friction between the bottom of the battery pack 20 and the bearing part 3 and generate greater resistance. After the battery pack 20 is moved into place, the height of the first belt moving mechanism 2 will be lower than the bearing part 3, so that most of the weight of the battery pack 20 directly acts on the bearing part 3, avoiding the first belt moving mechanism 2 from bearing the weight of the battery pack 20 for a long time, which can improve the durability of the first belt moving mechanism 2. At the same time, arranging the battery pack 20 on the bearing part 3 can also improve the positioning reliability of the battery pack 20 relative to the battery charging position 10. In other embodiments, if the various disadvantages caused by the long-term bearing of the battery pack 20 by the first belt moving mechanism 2 are not considered, the bearing part 3 may not be provided.

[0119] Among them, how the first belt moving mechanism 2 adjusts its height relative to the 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 prior art, so it will not be described in detail here.

[0120] like Figure 4 As shown, the battery charging position 10 also includes a first stop mechanism 71 and a first arrival sensor (not shown in the figure). The first stop mechanism 71 is also arranged on the surface of the bottom plate 12 of the position body 1. The specific position of the first stop mechanism 71 is arranged at one end away from the battery entrance and exit 11 along the first path A. The function of the first stop mechanism 71 is to stop the battery pack 20 at the first arrival position on the first path A, so as to accurately stop the battery pack 20 at the preset arrival position by means of physical limitation. The structure is simple and reliable. In this embodiment, the height of the first stop mechanism 71 in the non-stop state can be lower than the bottom surface of the battery pack 20, and when the battery pack 20 needs to be stopped, the first stop mechanism 71 rises so that the height is higher than the bottom surface of the battery pack 20, so as to achieve the purpose of physical limitation, so that the battery pack 20 stops accurately at the first arrival position. In other embodiments, the height of the first stop mechanism 7 can also be set to be fixed, that is, it remains in the stop state. At this time, the height of the first stop mechanism 71 is higher than the bottom surface of the battery pack 20.

[0121] The first in-position sensor is arranged on the first stop mechanism 71. The first in-position sensor is used to detect whether the battery pack 20 is located at the first in-position point. 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 point 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 point. The first signal is transmitted to the control motor of the first belt movement through a wire, so that the first belt moving mechanism 2 stops running. Through this closed-loop control method, the accuracy of the first belt moving mechanism 2 driving the battery pack 20 to stop at the first in-position point 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.

[0122] The battery charging compartment 10 also includes a first electrical connector 4, which is disposed on the compartment body 1 and has the function of docking with the second electrical connector on the battery pack 20 to enable the battery charging compartment 10 to charge the battery pack 20.

[0123] In this embodiment, Figure 3As shown, the first electrical connector 4 is arranged on the back side of the battery charging position 10, that is, the side away from the battery entrance and exit 11, and the number of the first stop mechanism 71 is two, which are respectively distributed on the left and right sides of the first electrical connector 4. When the battery pack 20 moves to the first arrival point driven by the first belt moving mechanism 2, the first electrical connector 4 can be electrically connected with the second electrical connector on the battery pack 20. In this embodiment, a second stop mechanism 72 can also be arranged in the position body 1, and the second stop mechanism 72 is specifically located between the first arrival point and the battery entrance and exit 11. When the first electrical connector 4 is electrically connected with the second electrical connector, the second stop mechanism 72 moves to the first path A to block the battery pack 20 from moving toward the battery entrance and exit, 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 limiting and preventing the battery pack 20 from escaping from the storage space body 1.

[0124] In other embodiments, the battery charging compartment 10 can be suitable for carrying and charging various types of battery packs. The so-called various types of battery packs refer to different types of battery packs having different lengths, widths, and heights. In this case, the second stop mechanism 72 can also move along the first path A, so that after the second stop mechanism 72 rises, the various types of battery packs can be physically limited.

[0125] 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:

[0126] 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 .

[0127] 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.

[0128] S13, when 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.

[0129] The above-mentioned battery replacement control method moves the battery pack 20 radially by the first belt moving mechanism 2 set in the storage space body 1, drives the battery pack 20 to move and dock with 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 storage space 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 types of battery packs 20 are moved into place in the storage space body 1.

[0130] 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 tightly positioned 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.

[0131] 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 for positioning contact with 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.

[0132] 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.

[0133] Example 2

[0134] This embodiment also provides a battery charging compartment, whose structure is substantially the same as that of the battery charging compartment provided in Embodiment 1, except that: Figure 8 and Fig. 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 entrance 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 not be directly connected to the first electrical connector 4.

[0135] The battery charging bin in this embodiment also includes a second belt moving mechanism 5 disposed on the bottom plate 12 of the bin body 1. The extension direction of the second belt moving mechanism 5 is perpendicular to the first belt moving mechanism 2. The second belt moving mechanism 5 is disposed 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. It can be seen from the figure that 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 second belt moving mechanism 5 until it is docked with the first electrical connector 4 to achieve the purpose of charging.

[0136] Specifically, in order to enable both the first belt moving mechanism 2 and the second belt moving mechanism 5 to drive the battery pack 20, the belt surfaces of the first belt moving mechanism 2 and the second belt moving mechanism 5 may be located at the same height but higher than the load-bearing portion 3. Alternatively, the belt surfaces of the first belt moving mechanism 2 and the second belt moving mechanism 5 and the load-bearing portion 3 are all located at the same height. In this case, in order to reduce the friction force on the surface of the load-bearing portion 3 and avoid the battery pack 20 from generating large friction with the surface of the load-bearing portion 3 when driven by the first belt moving mechanism 2 or the second belt moving mechanism 5, a ball bearing is provided on the upper surface of the load-bearing portion 3.

[0137] This embodiment provides a relative lifting scheme: 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.

[0138] How the first belt moving mechanism 2 adjusts its height relative to the second belt moving mechanism 5 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 in the prior art, so it will not be described in detail here. Of course, the lifting drive mechanism can also be set on the second belt moving mechanism 5 to make the second belt moving mechanism 5 rise and fall relative to the first belt moving mechanism 2.

[0139] In other embodiments, the battery charging compartment 10 may be suitable for carrying and / or charging various types of battery packs. The so-called various types of battery packs refer to that the length, width, and height of different types of battery packs may be different. At this time, the second stop mechanism 72 can also move along the first path A, so that after the second stop mechanism 72 rises, physical limiting of the various types of battery packs can be achieved.

[0140] 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:

[0141] 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 .

[0142] S22. After the battery pack 20 moves to a 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.

[0143] S23 . After the battery pack 20 moves along the second path B to electrically connect the second electrical connector to the first electrical connector 4 , the second belt moving mechanism 5 is controlled to stop running.

[0144] The above-mentioned battery replacement control method simultaneously sets the first belt moving mechanism 2 and the second belt moving mechanism 5 in the storage space body 1 to move the battery pack 20 along different paths, thereby driving the battery pack 20 to move and dock with the first electrical connector 4, thereby improving the position accuracy and docking reliability of the battery pack 20 in the storage space 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 storage space body 1.

[0145] The stop mechanism in this embodiment includes a first stop mechanism 71 and a second stop mechanism 72. The layout of the two stop mechanisms on the bottom plate 12 is as follows: Figure 8 As shown: the first stop mechanism 71 is arranged on the first path A, and the purpose is to stop the battery pack 20 at the first arrival point along the first path A. The second stop mechanism 72 is arranged on the second path B. After the first electrical connector 4 and the second electrical connector are in contact and electrically connected, the second stop mechanism 72 moves to the second path B and is used to stop the battery pack 20 from moving in the direction away from the first electrical connector 4. The purpose of setting the second stop 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 stop mechanism 71 and the second stop mechanism 72 can refer to the structures provided by the first stop mechanism 71 and the second stop mechanism 72 in Example 1.

[0146] In this embodiment, the first in-position sensor is arranged on the first stop mechanism, and can generate a first signal when the battery pack 20 is located at the first in-position position, and the first signal is used to control the first belt moving mechanism 2 to stop running, or to control the height of the first belt moving mechanism 2 to be lower than the second belt moving mechanism 5, or the two actions are performed simultaneously. The first signal is used as a basis to control the start and stop of the first belt moving mechanism 2 or to raise and lower it 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, and the purpose of precise control is achieved.

[0147] The first signal can also be used 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, so that the battery pack 20 is carried on the second belt moving mechanism 5, and the second belt moving mechanism 5 is started to move the battery pack 20.

[0148] In this embodiment, the battery charging position 10 also includes a second in-position sensor (not shown in the figure), which is arranged at one end of the second path B close to the first electrical connector 4. The function of the second in-position sensor is to detect whether the battery pack 20 is located at the second in-position point. The second in-position sensor is used to actively monitor the position of the battery pack 20, so as to timely obtain the timing of the battery pack 20 reaching the second in-position point under the drive of the second belt moving mechanism 5, and achieve the purpose of precise control. Specifically, the second in-position sensor can generate a second signal when the battery pack 20 is located at the second in-position point, and the second signal is used to control the second belt moving mechanism 5 to stop running, so as to stop the operation of the second belt moving mechanism 5 in time after the battery pack 20 moves into position. By means of closed-loop control, the position accuracy of the second belt moving mechanism 5 when driving the battery pack 20 to stop at the electrical connection with the first electrical connector 4 is improved, and the situation that the battery pack 20 over-extrudes the second electrical connector to damage the second electrical connector after moving too far is prevented.

[0149] Example 3

[0150] This embodiment also provides a battery charging compartment, whose structure is substantially the same as that of the battery charging compartment provided in Embodiment 2, except that: Fig.10 and Fig.11 As shown, the battery charging bin in this embodiment does not have a second belt moving mechanism 5. The battery charging bin includes a driving mechanism 6, which is also arranged on a side of the bin 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.

[0151] 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 in the direction closer to 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 with the second electrical connector on the battery pack 20.

[0152] In this embodiment, a second stopping mechanism 72 is also provided to support 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 .

[0153] Through the above structure, the driving mechanism 6 is provided to drive and change the position of the first electrical connector 4, so as to actively approach the battery pack 20 and electrically connect with the second electrical connector on the battery pack 20. This electrical connection method is simple and reliable, and can meet the purpose of electrically connecting with battery packs 20 of different models and specifications by adjusting the driving distance of the driving mechanism 6, and has good compatibility.

[0154] 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:

[0155] 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 .

[0156] 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 at the same time, the driving mechanism 6 is controlled to drive the first electrical connector 4 to approach the battery pack 20 so that the first electrical connector 4 is electrically connected to the second electrical connector on the battery pack 20.

[0157] The battery replacement control method improves the positioning accuracy and docking reliability of the battery pack 20 with the first electrical connector 4 in the storage compartment body 1 by controlling the driving mechanism 6 to drive the first electrical connector 4 to approach the battery pack 20. In addition, the scheme 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 storage compartment body 1, so as to adapt to storage compartment bodies 1 in various spaces and improve applicability.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
